Abstract

  • INTRODUCTION: Invasive squamous cell carcinoma (SCC) may present clinically with or without a horn.
    OBJECTIVE: To compare invasive SCC with or without horn presentation by anatomic site, tumor diameter, depth, and grade of differentiation.
    MATERIALS AND METHODS: The above characteristics of invasive SCC with or without horns were compared using a logistic regression model adjusted for potential confounders.
    RESULTS: There were 7.0% horns (n = 116) and 93.0% nonhorns (n = 1,550) in 1,666 cases. The median tumor diameter was 6 mm for horns, and 8 mm for nonhorn cases, p < .001. The median depth of invasion was 0.8 mm for horn cases and 1.3 mm for nonhorns, p < .001. Most cases were well-differentiated SCC for both horns (n = 102, 87.9%) and nonhorns (n = 1,265, 81.6%) p = .07. Horn cases had a borderline significant shift to well differentiation with moderate differentiation in 11.2% of cases (n = 13) and poor differentiation in 0.9% (n = 1).
    CONCLUSION: Horns presented on invasive SCC with reduced tumor diameters and reduced invasion depths compared to nonhorns. Horns presenting on invasive SCC were usually well differentiated. However, moderate and even poor differentiation can occur within a horn base.
  • Photodynamic Therapy2016-06-26 11:19:20 AM
      imageBACKGROUND: The American Society of Dermatologic Surgery (ASDS) periodically develops consensus documents for its members concerning various aspects of dermatologic surgery. Advances in photodynamic therapy (PDT) have been many and PDT use has been established in a variety of skin conditions.
    OBJECTIVE: The ASDS board of directors proposed a committee of experts in the field to develop consensus documents on different treatments. An expert panel reviewed the literature on PDT and discussed the findings. The consensus was reached with evidence-based recommendations on different clinical applications for PDT.
    PATIENTS AND METHODS: This consensus document includes discussions regarding PDT, including different photosensitizers and various light source activators, historical perspective, mechanism of action, various therapeutic indications and expected outcomes, pre- and post-care, and management of adverse outcomes.
    RESULTS: Photodynamic therapy is highly effective for pre-cancerous lesions, superficial nonmelanoma skin cancers, inflammatory acne vulgaris and other conditions. New protocols including laser mediated PDT significantly improve results for several indications.
    CONCLUSION: The ASDS consensus document on PDT will be helpful for educating members on safe and effective PDT for a variety of indications.

  • Basosquamous Carcinoma2016-06-26 11:18:56 AM
    Controversy, Advances, and Future Directions.BACKGROUND: Basosquamous carcinoma is a rare cutaneous neoplasm that has caused considerable controversy as to its classification, pathogenesis, and management.
    OBJECTIVE: To review and summarize current literature on the definition, pathogenesis, incidence, and management of basosquamous carcinoma.
    MATERIALS AND METHODS: Through December 2015, an electronic search of the Pubmed database was performed using combinations of basosquamous carcinoma and metatypical basal cell carcinoma as search terms.
    RESULTS: A selection of 39 publications including case reports and series, retrospective studies, and systematic reviews of the literature were included. Descriptions of the definition of basosquamous carcinoma, clinical behavior, histopathological characteristics, current treatment therapies, and future advances are summarized.
    CONCLUSION: This systematic review provides a comprehensive overview of the current understanding of basosquamous carcinoma. Further study is required to elucidate the mechanisms driving the formation of this aggressive tumor.

  • Use of Porcine Xenografts in Dermatology Surgery2016-06-26 11:18:45 AM
    The Mayo Clinic Experience.BACKGROUND: Knowledge regarding the use of xenografts in cutaneous surgery is limited.
    OBJECTIVE: We sought to better understand the utility, outcomes, and complications of porcine xenograft applications in cutaneous surgery.
    METHODS AND MATERIALS: A single center, retrospective study of patients with porcine xenograft applications was completed. Characteristics of tumors, surgical procedures, resulting wound beds, follow-up care, and final length of follow-up were determined, and statistical analysis was conducted.
    RESULTS: Of 225 porcine xenograft placements in 220 patients, the majority of tumors were nonmelanoma skin cancers (89%) and similarly divided between the head (excepting nose/ear), nose, ear, and extremities. Both Mohs and standard excision resulted in a 5.7 cm2 mean area of surgical defect, with the majority closed by porcine xenograft only (84.1%), and healing by secondary intention (97.3%). The area of surgical defect and topical antibiotics contributed to increased length of time to final follow-up.
    CONCLUSION: The data represent the largest series of biologic dressings in cutaneous surgery and demonstrate the applicability and safety of porcine xenografts. We recommend consideration of porcine xenografts in the appropriate clinical context, to augment secondary intention.

  • Mitochondrial dysfunction induced by mitochondria-related [beta]-amyloid (A[beta]) accumulation2016-06-26 11:18:35 AM
    Frontal cortical mitochondrial dysfunction and mitochondria-related [beta]-amyloid accumulation by chronic sleep restriction in mice.Mitochondrial dysfunction induced by mitochondria-related [beta]-amyloid (A[beta]) accumulation is increasingly being considered a novel risk factor for sporadic Alzheimer’s disease pathophysiology. The close relationship between chronic sleep restriction (CSR) and cortical A[beta] elevation was confirmed recently. By assessing frontal cortical mitochondrial function (electron microscopy manifestation, cytochrome C oxidase concentration, ATP level, and mitochondrial membrane potential) and the levels of mitochondria-related A[beta] in 9-month-old adult male C57BL/6J mice subjected to CSR and as an environmental control (CO) group, we aimed to evaluate the association of CSR with mitochondrial dysfunction and mitochondria-related A[beta] accumulation. In this study, frontal cortical mitochondrial dysfunction was significantly more severe in CSR mice compared with CO animals. Furthermore, CSR mice showed higher mitochondria-associated A[beta], total A[beta], and mitochondria-related [beta]-amyloid protein precursor (A[beta]PP) levels compared with CO mice. In the CSR model, mouse frontal cortical mitochondrial dysfunction was correlated with mitochondria-associated A[beta] and mitochondria-related A[beta]PP levels. However, frontal cortical mitochondria-associated A[beta] levels showed no significant association with cortical total A[beta] and mitochondrial A[beta]PP concentrations. These findings indicated that CSR-induced frontal cortical mitochondrial dysfunction and mitochondria-related A[beta] accumulation, which was closely related to mitochondrial dysfunction under CSR.

  • Seizures during the intraoperative monitoring of motor evoked potentials (MEPs) elicited by electrical brain stimulation2016-06-26 11:18:30 AM
    OBJECTIVE The purpose of this study was to investigate the incidence of seizures during the intraoperative monitoring of motor evoked potentials (MEPs) elicited by electrical brain stimulation in a wide spectrum of surgeries such as those of the orthopedic spine, spinal cord, and peripheral nerves, interventional radiology procedures, and craniotomies for supra- and infratentorial tumors and vascular lesions. METHODS The authors retrospectively analyzed data from 4179 consecutive patients who underwent surgery or an interventional radiology procedure with MEP monitoring. RESULTS Of 4179 patients, only 32 (0.8%) had 1 or more intraoperative seizures. The incidence of seizures in cranial procedures, including craniotomies and interventional neuroradiology, was 1.8%. In craniotomies in which transcranial electrical stimulation (TES) was applied to elicit MEPs, the incidence of seizures was 0.7% (6/850). When direct cortical stimulation was additionally applied, the incidence of seizures increased to 5.4% (23/422). Patients undergoing craniotomies for the excision of extraaxial brain tumors, particularly meningiomas (15 patients), exhibited the highest risk of developing an intraoperative seizure (16 patients). The incidence of seizures in orthopedic spine surgeries was 0.2% (3/1664). None of the patients who underwent surgery for conditions of the spinal cord, neck, or peripheral nerves or who underwent cranial or noncranial interventional radiology procedures had intraoperative seizures elicited by TES during MEP monitoring. CONCLUSIONS In this largest such study to date, the authors report the incidence of intraoperative seizures in patients who underwent MEP monitoring during a wide spectrum of surgeries such as those of the orthopedic spine, spinal cord, and peripheral nerves, interventional radiology procedures, and craniotomies for supra- and infratentorial tumors and vascular lesions. The low incidence of seizures induced by electrical brain stimulation, particularly short-train TES, demonstrates that MEP monitoring is a safe technique that should not be avoided due to the risk of inducing seizures.
  • Hemangiomas of the cavernous sinus2016-06-26 11:18:17 AM
    Gamma Knife radiosurgery for hemangioma of the cavernous sinus: Journal of Neurosurgery, Ahead of Print.
    OBJECTIVE Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. A direct microsurgical approach usually results in massive hemorrhage and incomplete tumor resection. Although stereotactic radiosurgery (SRS) has emerged as a therapeutic alternative to microsurgery, outcome studies are few. Authors of the present study evaluated the role of SRS for CSH. METHODS An international multicenter study was conducted to review outcome data in 31 patients with CSH. Eleven patients had initial microsurgery before SRS, and the other 20 patients (64.5%) underwent Gamma Knife SRS as the primary management for their CSH. Median age at the time of radiosurgery was 47 years, and 77.4% of patients had cranial nerve dysfunction before SRS. Patients received a median tumor margin dose of 12.6 Gy (range 12–19 Gy) at a median isodose of 55%. RESULTS Tumor regression was confirmed by imaging in all 31 patients, and all patients had greater than 50% reduction in tumor volume at 6 months post-SRS. No patient had delayed tumor growth, new cranial neuropathy, visual function deterioration, adverse radiation effects, or hypopituitarism after SRS. Twenty-four patients had presented with cranial nerve disorders before SRS, and 6 (25%) of them had gradual improvement. Four (66.7%) of the 6 patients with orbital symptoms had symptomatic relief at the last follow-up. CONCLUSIONS Stereotactic radiosurgery was effective in reducing the volume of CSH and attaining long-term tumor control in all patients at a median of 40 months. The authors’ experience suggests that SRS is a reasonable primary and adjuvant treatment modality for patients in whom a CSH is diagnosed.

    BACKGROUND: Laser pretreatment of skin can be used to enable drugs used in dermatology to penetrate the skin to the depth necessary for their effect to take place.
    OBJECTIVE: To compare the permeation of tranexamic acid after conventional non-fractionated ablative Er:YAG and CO2 laser pretreatment in a laser-aided transdermal delivery system.
    MATERIALS AND METHODS: An erbium-doped yttrium aluminium garnet (Er:YAG) and a CO2 laser were used to pretreat dorsal porcine skin. Scanning electron microscopy was used to examine disruption of the skin surface. Confocal laser scanning microscopy was used to determine the depth of penetration of a reporter molecule (fluorescein isothiocyanate) into the skin. A Franz diffusion assembly was used to examine fluency-related increases in transdermal delivery of transexamic acid.
    RESULTS: Transdermal delivery of tranexamic acid increased as Er:YAG laser fluency increased. Transdermal delivery was higher when CO2 laser pretreatment was used than when Er:YAG laser pretreatment was used, but a “ceiling effect” was present and increasing the wattage did not cause a further increase in delivery. CO2 laser pretreatment also caused more extensive and deeper skin disruption than Er:YAG laser pretreatment.
    CONCLUSION: For conventional, non-fractionated ablative laser pretreatment, the Er:YAG laser would be an optimal choice to enhance transdermal penetration of transexamic acid.

Mohamed, Kate A. Hutcheson, Emma B. Holliday, Nikhil G. Thaker, Erich M. Sturgis, Merrill S. Kies, X. Ronald Zhu, Radhe Mohan, Steven J. Frank
    BackgroundOwing to its physical properties, intensity-modulated proton therapy (IMPT) used for patients with oropharyngeal carcinoma has the ability to reduce the dose to organs at risk compared to intensity-modulated radiotherapy (IMRT) while maintaining adequate tumor coverage. Our aim was to compare the clinical outcomes of these two treatment modalities.MethodsWe performed a 1:2 matching of IMPT to IMRT patients. Our study cohort consisted of IMPT patients from a prospective quality of life study and consecutive IMRT patients treated at a single institution during the period 2010–2014. Patients were matched on unilateral/bilateral treatment, disease site, human papillomavirus status, T and N status, smoking status, and receipt of concomitant chemotherapy. Survival analyzes were performed using a Cox model and binary toxicity endpoints using a logistic regression analysis.ResultsFifty IMPT and 100 IMRT patients were included. The median follow-up time was 32months. There were no imbalances in patient/tumor characteristics except for age (mean age 56.8years for IMRT patients and 61.1years for IMPT patients, p-value=0.010). Statistically significant differences were not observed in overall survival (hazard ratio (HR)=0.55; 95% confidence interval (CI): 0.12–2.50, p-value=0.44) or in progression-free survival (HR=1.02; 95% CI: 0.41–2.54; p-value=0.96). The age-adjusted odds ratio (OR) for the presence of a gastrostomy (G)-tube during treatment for IMPT vs IMRT were OR=0.53; 95% CI: 0.24–1.15; p-value=0.11 and OR=0.43; 95% CI: 0.16–1.17; p-value=0.10 at 3months after treatment. When considering the pre-planned composite endpoint of grade 3 weight loss or G-tube presence, the ORs were OR=0.44; 95% CI: 0.19–1.0; p-value=0.05 at 3months after treatment and OR=0.23; 95% CI: 0.07–0.73; p-value=0.01 at 1year after treatment.ConclusionOur results suggest that IMPT is associated with reduced rates of feeding tube dependency and severe weight loss without jeopardizing outcome. Prospective multicenter randomized trials are needed to validate such findings.

  • Radiotherapy and immune checkpoints inhibitors for advanced melanoma2016-06-26 11:31:52 AM

    Author(s): Andrea Riccardo Filippi, Paolo Fava, Serena Badellino, Chiara Astrua, Umberto Ricardi, Pietro Quaglino
    IntroductionThe therapeutic landscape of metastatic melanoma drastically changed after the introduction of targeted therapies and immunotherapy, in particular immune checkpoints inhibitors (ICI). In recent years, positive effects on the immune system associated to radiotherapy (RT) were discovered, and radiation has been tested in combination with ICI in both pre-clinical and clinical studies (many of them still ongoing). We here summarize the rationale and the preliminary clinical results of this approach.Materials and methodsIn the first part of this review article, redacted with narrative non-systematic methodology, we describe the clinical results of immune checkpoints blockade in melanoma as well as the biological basis for the combination of ICI with RT; in the second part, we systematically review scientific publications reporting on the clinical results of the combination of ICI and RT for advanced melanoma.ResultsThe biological and mechanistic rationale behind the combination of ICI and radiation is well supported by several preclinical findings. Retrospective observational series and few prospective trials support the potential synergistic effect between radiation and ICI for metastatic melanoma.ConclusionRT may potentiate anti-melanoma activity of ICI by enhancing response on both target and non-target lesions. Several prospective trials are ongoing with the aim of further exploring this combination in the clinical setting, hopefully confirming initial observations and opening a new therapeutic window for advanced melanoma patients.

    Background and purposeThe aim of this study was to develop and validate a method to select head and neck cancer patients for adaptive radiotherapy (ART) pre-treatment. Potential pre-treatment selection criteria presented in recent literature were included in the analysis.Materials and methodsDeviations from the planned parotid gland mean dose (PG ΔDmean) were estimated for 113 head and neck cancer patients by re-calculating plans on repeat CT scans. Uni- and multivariable linear regression analyses were performed to select pre-treatment parameters, and ROC curve analysis was used to determine cut off values, for selecting patients with a PG dose deviation larger than 3Gy. The patient selection method was validated in a second patient cohort of 43 patients.ResultsAfter multivariable analysis, the planned PG Dmean remained the only significant parameter for PG ΔDmean. A sensitivity of 91% and 80% could be obtained using a threshold of PG Dmean of 22.2Gy, for the development and validation cohorts, respectively. This would spare 38% (development cohort) and 24% (validation cohort) of patients from the labour-intensive ART procedure.ConclusionsThe presented method to select patients for ART pre-treatment reduces the labour of ART, contributing to a more effective allocation of the department resources.

    Background and purposeCurrently, there is no consensus on dose prescription in image guided adaptive brachytherapy (IGABT) in locally advanced cervical cancer. The purpose of this study was to provide evidence based recommendations for tumor dose prescription based on results from a multi-center patient series (retroEMBRACE).Materials and methodsThis study analyzed 488 locally advanced cervical cancer patients treated with external beam radiotherapy±chemotherapy combined with IGABT. Brachytherapy contouring and reporting was according to ICRU/GEC-ESTRO recommendations. The Cox Proportional Hazards model was applied to analyze the effect on local control of dose-volume metrics as well as overall treatment time (OTT), dose rate, chemotherapy, and tumor histology.ResultsWith a median follow up of 46months, 43 local failures were observed. Dose (D90) to the High Risk Clinical Target Volume (CTVHR) (p=0.022, HR=0.967 per Gy) was significant for local control, whereas increasing CTVHR volume (p=0.004, HR=1.017 per cm3), and longer OTT (p=0.004, HR=1.023 per day) were associated with worse local control. Histology (p=0.084), chemotherapy (p=0.49) and dose rate (p=1.00) did not have significant impact on local control. Separate analyses according to stage of disease showed that dose to CTVHR, residual gross tumor volume (GTVres), and Intermediate Risk CTV (CTVIR) has significant impact on local control.ConclusionCTVHR dose of ⩾85Gy (D90) delivered in 7weeks provides 3-year local control rates of >94% in limited size CTVHR (20cm3), >93% in intermediate size (30cm3) and >86% in large size (70cm3) CTVHR. CTVIR and GTVres dose of ⩾60Gy and ⩾95Gy (D98) leads to similar local control. A dose of 5Gy (CTVHR) is required to compensate an increase of OTT by one week. Increased CTVHR volume by 10cm3 requires additional 5Gy for equivalent local control.

  • Human Foramen Magnum Area and Posterior Cranial Fossa Volume Growth in Relation to Cranial Base Synchondrosis Closure in the Course of Child Development.2016-06-26 11:29:07 AM

    Abstract

    BACKGROUND: To date, no study has confronted the evolution of the foramen magnum area (FMA) and the posterior cranial fossa volume (PCFV) with the degree of cranial base synchondrosis ossification.
    OBJECTIVE: To illustrate these features in healthy children.
    METHODS: The FMA, the PCFV, and the ossification of 12 synchondroses according to the Madeline and Elster scale were retrospectively analyzed in 235 healthy children using millimeter slices on a computed tomography scan.
    RESULTS: The mean FMA of 6.49 cm2 in girls was significantly inferior to the FMA of 7.67 cm2 in boys (P < .001). In both sexes, the growth evolved in a 2-phase process, with a phase of rapid growth from birth to 3.75 years old (yo) followed by a phase of stabilization. In girls, the first phase was shorter (ending at 2.6 yo) than in boys (ending at 4.33 yo) and proceeded at a higher rate. PCFV was smaller in girls (P < .001) and displayed a biphasic pattern in the whole population, with a phase of rapid growth from birth to 3.58 yo followed by a phase of slow growth until 16 yo. In girls, the first phase was more active and shorter (ending at 2.67 yo) than in boys (ending at 4.5 yo). The posterior interoccipital synchondroses close first, followed by the anterior interoccipital and occipitomastoidal synchondroses, the lambdoid sutures simultaneously, then the petro-occipital and spheno-occipital synchondroses simultaneously.
    CONCLUSION: The data provide a chronology of synchondrosis closure. We showed that FMA and PCFV are constitutionally smaller in girls at birth (P <= .02) and suggest that a sex-related difference in the FMA is related to earlier closure of anterior interoccipital synchondroses in girls (P = .01).

  • Reversible Edema-Like Changes Along the Optic Tract Following Pipeline-Assisted Coiling of a Large Anterior Communicating Artery Aneurysm.2016-06-26 11:29:00 AM
    Reversible Edema-Like Changes Along the Optic Tract Following Pipeline-Assisted Coiling of a Large Anterior Communicating Artery Aneurysm.Aneurysmal volume expansion after endovascular treatment is caused by intra-aneurysmal thrombosis in the early postembolization period. Although postembolization mass effect on cranial nerves and other adjacent structures has been previously reported, we are unaware of reports involving the anterior visual pathway. A 66-year-old woman with a 2-week history of blurred vision without headache was found to have a large, unruptured anterior communicating artery aneurysm. One month after endovascular treatment of the aneurysm with coiling and flow diversion, the patient developed decreased vision in her right eye and a left homonymous hemianopia. Magnetic resonance imaging demonstrated compression of the right optic nerve, chiasm, and edema of the right optic tract. The patient was treated with a course of high dose corticosteroids, and over the course of several weeks, her vision improved and the optic tract edema resolved. We alert clinicians to this rare but potentially reversible visual complication of endovascular treatment of intracranial aneurysms.

  • Congenital Tonic Pupils Associated With Congenital Central Hypoventilation Syndrome and Hirschsprung Disease.2016-06-26 11:28:46 AM
    Congenital Tonic Pupils Associated With Congenital Central Hypoventilation Syndrome and Hirschsprung Disease.:Autonomic dysfunction can be associated with pupillary abnormalities. We describe a rare association of tonic pupils, congenital central hypoventilation syndrome, and Hirschsprung disease in a newborn with a mutation in the PHOX2B gene, a key regulator of neural crest cells. Hirschsprung disease is characterized by the congenital absence of neural crest-derived intrinsic ganglion cells. Tonic pupils may result from an abnormality of the ciliary ganglion, another structure of neural crest origin. The close association of these conditions in this child suggests a common abnormality in neural crest migration and differentiation.

    Neodymium-Doped Yttrium Aluminium Garnet Laser Treatment of Pediatric Venous Malformation in the Oral CavityimageBACKGROUND: Treatment of venous malformations in the orofacial region remains a challenge. Laser therapy is an alternative treatment in inoperable cases.
    OBJECTIVE: To retrospectively evaluate the effectiveness and complications associated with neodymium-doped yttrium aluminium garnet (Nd:YAG) laser treatment of oral venous malformations.
    MATERIALS AND METHODS: A total of 10 children (mean age: 7.3 years; range: 10 months-15 years) with oral venous malformation were treated with Nd:YAG laser during 2005 to 2013. Clinical improvement, including degree of color lightening and size reduction, and treatment complications, including dyspigmentation, textural change, and scarring were evaluated.
    RESULTS: Color clearing of 51% to 75% and >75% was seen in 25% and 45% of patients, respectively. Size reduction of 25% to 50%, 51% to 75%, and >75% was observed in 30%, 15%, and 45% of patients, respectively. Mild and moderate scarring was observed in 15% and 5% of cases, respectively.
    CONCLUSION: Nd:YAG laser is a promising alternative treatment in pediatric patients with inoperable venous malformations in the oral cavity. Mild to moderate scarring was the most common complication.

    CONCLUSION: For conventional, non-fractionated ablative laser pretreatment, the Er:YAG laser would be an optimal choice to enhance transdermal penetration of transexamic acid.

    Continuous Wave Potassium Titanyl Phosphate Laser Treatment is Safe and Effective for Xanthelasma Palpebrarum: BACKGROUND: Although not an accepted standard treatment, the 532-nm continuous wave potassium titanyl phosphate (CW-KTP) laser might be a powerful device to treat xanthelasma palpebrarum (XP).
    OBJECTIVE: To determine the safety and efficacy of CW-KTP laser treatment for XP.
    MATERIALS AND METHODS: Between January 2013 and January 2015, 30 consecutive patients with XP were treated with a 532-nm CW-KTP laser (spot size: 0.9 mm, power: 5.0 W, fluence: 36–38 J/cm2, pulse width: 46 milliseconds, frequency: 2.0 Hz, passes per session: 3). In a retrospective study design, safety and efficacy data were collected and analyzed.
    RESULTS: Overall, 29/30 (97%) of patients had an excellent cosmetical result. Downtime was 1 week with crusted lesions. Although slight hypopigmentation was common, only 1/30 (3%) patients had hypopigmentation that was more than expected. Recurrences (13/30; 43%) were frequent, so that yearly maintenance therapy was warranted. No major side effects were noticed.
    CONCLUSION: Continuous wave KTP laser therapy is safe and highly effective for XP, although regular follow-up treatments are often necessary to maintain the achieved cosmetic results.
  • Aging in the Male Face:2016-06-26 11:27:31 AM
     Intrinsic and Extrinsic FactorsBACKGROUND: Gender is one of the most significant factors that influence facial anatomy and behavior, both key factors in the aging process.
    OBJECTIVE: To review male facial anatomy, physiology, and behavior and how it contributes to sexual dimorphism in facial aging.
    METHODS: A MEDLINE search was performed for publications on gender differences in facial anatomy, aging, cutaneous physiology, and behavior.
    RESULTS: There are differences in both intrinsic and extrinsic aging factors in men. Men have a thicker epidermis and dermis with more active cutaneous appendages including hair growth. Male skin has a reduced antioxidant capacity and increased ultraviolet-induced immunosuppression. The male face is larger and has a unique square shape with less subcutaneous soft tissue, especially at the medial cheek. Men are also more prone to smoking and exhibiting poor sun-protective behavior. The differences in intrinsic and extrinsic aging factors contribute to poor facial aging in men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss.
    CONCLUSION: This review provides insight into the factors contributing to accelerated male facial aging. Understanding gender differences in aging will help physicians tailor cosmetic treatments for men and minimize extrinsic aging factors.
  • Triple combination therapy (TCT) with the active pharmaceutical ingredients hydroquinone 5%, tretinoin 0.03%, and dexamethasone 0.03% is often used for skin-lightening2016-06-26 11:27:18 AM
      imageBACKGROUND: Quality-switched (QS) laser therapy is a safe and well-established treatment option for removing solar lentigines. Triple combination therapy (TCT) with the active pharmaceutical ingredients hydroquinone 5%, tretinoin 0.03%, and dexamethasone 0.03% is often used for skin-lightening.
    OBJECTIVE: This prospective, open-label trial compares the efficacy and safety of a QS Ruby laser (QSRL) and a TCT in the treatment of solar lentigines.
    METHODS: In total, 15 patients with symmetrically distributed solar lentigines on the back of both hands were included. The lesions on the back of the right hand were treated in one or 2 sessions with a QSRL, the ones on the back of the left hand with a TCT for 7 weeks accompanied by UV protection. Clinical results were evaluated 4 weeks, 8 weeks, and 20 weeks after baseline.
    RESULTS: Treatment with QSRL provided significant lightening (p = .01) compared with TCT. Both procedures were generally well-tolerated. Comparing the side effects, the laser produced significantly more crusting and hyperpigmentation than the TCT.
    CONCLUSION: Both QSRL and TCT were capable in reducing solar lentigines in Fitzpatrick skin Type I to IV with an acceptable side effect profile. The QSRL provides faster, superior, and long lasting lightening compared with TCT.
  • Motor Unit Number Estimation Based on High-Density Surface Electromyography Decomposition2016-06-26 11:27:15 AM
    Motor unit number estimation (MUNE) techniques are clinically useful by estimating the number of functioning motor units in a muscle, which can serve as a biomarker for the progression of motor neuron diseases or neuromuscular disorders. Various MUNE methods have been developed since the incremental counting technique was introduced in 1971 (McComas et al., 1971). The main limitation with the incremental counting technique is the problem known as “alternation”, which leads to an erroneous overestimation of the MUNE.

  • Effects of chronic neck-shoulder pain on normalized mutual information analysis of surface electromyography during functional tasks2016-06-26 11:27:15 AM
    Neck and shoulder pain is a common problem that affects a large number of people worldwide (Van Tulder et al., 2007). This problem is exacerbated by the escalating use of electronic devices such as smartphones and portable tablet computers (Berolo et al., 2011). The research concerning the etiology of chronic neck-shoulder pain has mainly focused on the study of muscle activation in the postural muscles such as cervical erector spinae (CES) and upper trapezius (UT) muscle (Visser and van Dieën 2006).

  • Reversed cortical over-activity during movement imagination following neurofeedback treatment for central neuropathic pain2016-06-26 11:27:15 AM
    Central neuropathic pain (CNP) is a frequent secondary consequence of spinal cord injury (SCI), affecting about 40% of patients (Siddall et al. 2003). Although CNP is caused by an injury to the somatosensory system (Haanpää et al. 2011) it can show first symptoms years after SCI. Neuroimaging studies have demonstrated changes in the resting state brain activity in the presence of CNP, which is reflected in increased thalamo-cortical coherence in the theta band (Stern et al. 2006, Sarnthein and Jeandmond 2008), as well as increased resting state EEG power and a dominant alpha frequency shift towards lower frequencies (Stern et al.

  • What is the optimal task difficulty for reinforcement learning of brain self-regulation?2016-06-26 11:27:15 AM
    Neurofeedback and brain-interface technology are being increasingly applied in fields of research aiming to restore upper-limb functionality in stroke survivors. Greater gains are currently being achieved by subacute (Pichiorri et al. 2015) than by chronic patients (Ang et al. 2014). On the basis of the neurophysiological correlates of motor imagery (Kaiser et al. 2011) and motor cortex excitability (Takemi et al. 2013; Kraus et al. 2016a), such as modulation of β-power (15-30 Hz), these devices may provide an effective backdoor to the motor system (Sharma 2006; Bauer et al.

  • Intradural extramedullary spinal tumor2016-06-26 11:22:18 AM
    Improved patient quality of life following intradural extramedullary spinal tumor resection: Journal of Neurosurgery: Spine, Ahead of Print.

    OBJECTIVE Resection significantly improves the clinical symptoms and functional outcomes of patients with intradural extramedullary tumors. However, patient quality of life following resection has not been adequately investigated. The aim in this retrospective analysis of prospectively collected quality of life outcomes is to analyze the efficacy of resection of intradural extramedullary spinal tumors in terms of quality of life markers. METHODS A retrospective review of a single institutional neurosurgical administrative database was conducted to analyze clinical data. The Oswestry Disability Index (ODI), visual analog scale (VAS) for pain, and the EQ-5D-3 L descriptive system were used to analyze quality of life preoperatively, less than 1 month postoperatively, 1–3 months postoperatively, 3–12 months postoperatively, and more than 12 months postoperatively. RESULTS The ODI scores increased perioperatively at the < 1-month follow-up from 36 preoperatively to 47. Relative to preoperative values, the ODI score decreased significantly at 1–3, 3–12, and > 12 months to 23, 17, and 20, respectively. VAS scores significantly decreased from 6.1 to 3.5, 2.4, 2.0, and 2.9 at the < 1-month, 1- to 3-, 3- to 12-, and > 12-month follow-ups, respectively. EQ-5D mobility significantly worsened at the < 1-month follow-up but improved at the 3- to 12-and > 12-month follow-ups. EQ-5D self-care significantly worsened at the < 1-month follow-up but significantly improved by the 3- to 12-month follow-up. EQ-5D usual activities improved at the 1- to 3-, 3- to 12-, and > 12-month follow-ups. EQ-5D pain and discomfort significantly improved at all follow-up points. EQ-5D anxiety and depression significantly improved at 1- to 3-month and 3- to 12-month follow-ups. CONCLUSIONS Resection of intradural extramedullary spine tumors appears to significantly improve patient quality of life by decreasing patient disability and pain and by improving each of the EQ-5D domains.

  • Re-irradiation stereotactic body radiotherapy for spinal metastases2016-06-26 11:22:18 AM
    a multi-institutional outcome analysis: Journal of Neurosurgery: Spine, Ahead of Print.

    OBJECTIVE This study is a multi-institutional pooled analysis specific to imaging-based local control of spinal metastases in patients previously treated with conventional external beam radiation therapy (cEBRT) and then treated with re-irradiation stereotactic body radiotherapy (SBRT) to the spine as salvage therapy, the largest such study to date. METHODS The authors reviewed cases involving 215 patients with 247 spinal target volumes treated at 7 institutions. Overall survival was calculated on a patient basis, while local control was calculated based on the spinal target volume treated, both using the Kaplan-Meier method. Local control was defined as imaging-based progression within the SBRT target volume. Equivalent dose in 2-Gy fractions (EQD2) was calculated for the cEBRT and SBRT course using an α/β of 10 for tumor and 2 for both spinal cord and cauda equina. RESULTS The median total dose/number of fractions of the initial cEBRT was 30 Gy/10. The median SBRT total dose and number of fractions were 18 Gy and 1, respectively. Sixty percent of spinal target volumes were treated with single-fraction SBRT (median, 16.6 Gy and EQD2/10 = 36.8 Gy), and 40% with multiple-fraction SBRT (median 24 Gy in 3 fractions, EQD2/10 = 36 Gy). The median time interval from cEBRT to re-irradiation SBRT was 13.5 months, and the median duration of patient follow-up was 8.1 months. Kaplan-Meier estimates of 6- and 12-month overall survival rates were 64% and 48%, respectively; 13% of patients suffered a local failure, and the 6- and 12-month local control rates were 93% and 83%, respectively. Multivariate analysis identified Karnofsky Performance Status (KPS) < 70 as a significant prognostic factor for worse overall survival, and single-fraction SBRT as a significant predictive factor for better local control. There were no cases of radiation myelopathy, and the vertebral compression fracture rate was 4.5%. CONCLUSIONS Re-irradiation spine SBRT is effective in yielding imaging-based local control with a clinically acceptable safety profile. A randomized trial would be required to determine the optimal fractionation.

  • Retro-odontoid pseudotumors are considered to be associated with atlantoaxial instability in patients with rheumatoid arthritis (RA)2016-06-26 11:22:18 AM
    Factors associated with retro-odontoid soft-tissue thickness in rheumatoid arthritis: Journal of Neurosurgery: Spine, Ahead of Print.

    OBJECTIVE Increasing soft-tissue mass posterior to the odontoid process causes spinal cord compression. Retro-odontoid pseudotumors are considered to be associated with atlantoaxial instability in patients with rheumatoid arthritis (RA), but the exact mechanism by which these lesions develop has not been elucidated. The purpose of this study was to identify the relationships between retro-odontoid soft-tissue (ROST) thickness and radiological findings or clinical data in patients with RA. METHODS A total of 201 patients with RA who had been followed up at the outpatient clinic of the authors’ institution were enrolled in this study. ROST thickness was evaluated on midsagittal T1-weighted MRI. The correlations between ROST thickness and radiographic findings or clinical data on RA were examined. The independent factors related to ROST thickness were analyzed using stepwise multiple regression analysis. RESULTS The average thickness of ROST was 3.0 ± 1.4 mm. ROST thickness showed an inverse correlation with disease duration (r = −0.329, p < 0.01), Steinbrocker stage (r = −0.284, p < 0.01), the atlantodental interval (ADI) in the neutral position (r = −0.326, p < 0.01), the ADI in the flexion position (r = −0.383, p < 0.01), and the ADI in the extension position (r = −0.240, p < 0.01). On stepwise multiple regression analysis, ADI in the flexion position and Steinbrocker stage were independent factors associated with ROST thickness. CONCLUSIONS Although the correlations were not strong, ROST thickness in patients with RA was inversely correlated with ADI and Steinbrocker stage. In other words, ROST thickness tends to be smaller as atlantoaxial instability and peripheral joint destruction worsen.

  • Repetitive transcranial magnetic stimulation for rehabilitation of poststroke dysphagia2016-06-26 11:22:18 AM
    A randomized, double-blind clinical trial.:
    http:--linkinghub.elsevier.com-ihub-imag
    Authors: Du J, Yang F, Liu L, Hu J, Cai B, Liu W, Xu G, Liu X

    Abstract

    OBJECTIVE: This randomized, sham-controlled, double-blind study was conducted to investigate the effects of high-frequency versus low-frequency repetitive transcranial magnetic stimulation (rTMS) on patients with poststroke dysphagia during early rehabilitation.

    METHODS: Forty patients with poststroke dysphagia were randomized to receive five daily sessions of sham, 3-Hz ipsilesional, or 1-Hz contralesional rTMS. Swallowing function, the severity of stroke and functional disability, and cortical excitability were examined before, immediately after five daily sessions, as well as the first, second, and third month after the last session.

    RESULTS: At baseline, no significant differences between groups were observed in terms of demographic and clinical rating scales. However, a significantly greater improvement in swallowing function as well as functional disability was observed after real rTMS when compared with sham rTMS, which remained 3 months after the end of the treatment sessions. In addition, 1-Hz rTMS increased cortical excitability of the affected hemisphere and decreased that of the non-affected hemisphere; however, 3-Hz rTMS only increased cortical excitability of the affected hemisphere.

    CONCLUSION: rTMS (both high and low frequency) improved swallowing recovery in patients with poststroke dysphagia, and the effects lasted for at least 3 months.

    SIGNIFICANCE: rTMS appears to be a beneficial therapeutic modality for patients with dysphagia during the early phase of stroke.

    Abstract

    A palatal augmentation prosthesis (PAP) is used to facilitate improvement in the speech and swallowing functions of patients with tongue resection or tongue movement disorders. However, a PAP’s effect is limited in cases where articulation disorder is severe due to wide glossectomy and/or segmental mandibulectomy. In this paper, we describe speech outcomes of a patient with an articulation disorder following glossectomy and segmental mandibulectomy. We used a palatal plate (PP) based on a PAP, along with an artificial tongue (KAT). Speech improvement was evaluated by a standardized speech intelligibility test consisting of 100 syllables. The speech intelligibility score was significantly higher when the patient wore both the PP and KAT than when he wore neither (p=0.013). The conversational intelligibility score was significantly improved with the PP and KAT than without PP and KAT (p=0.024). These results suggest that speech function can be improved in patients with hard tissue defects with segmental mandibulectomy using both a PP and a KAT. The nature of the design of the PP and that of the KAT will allow these prostheses to address a wide range of tissue defects.

  • Esophageal atresia (EA),Severe respiratory morbidity and gastroesophageal reflux (GER) symptoms2016-06-26 11:22:18 AM
    Physiological Studies at 7 Years of Age in Children Born with Esophageal Atresia.:
    http:--http://ift.tt/1SvbKVd
    Authors: Olbers J, Gatzinsky V, Jönsson L, Friberg LG, Abrahamsson K, Sillén U, Gustafsson P

    Abstract

    OBJECTIVE: For many years, esophageal atresia (EA) has been curable by surgery. However, severe respiratory morbidity and gastroesophageal reflux (GER) symptoms remain a problem in many patients. The purpose of this study was to describe respiratory and esophageal morbidity, esophageal function, and lung function, including the small airways, in patients with the most common type of the malformation (EA with a distal fistula).

    METHODS: The study comprised 26 children undergoing surgery for EA, who had performed respiratory and esophageal function studies at the age of 7 years in a follow-up program. The study design was retrospective analysis of both these 7-year functional investigations and esophageal and respiratory morbidity from birth to the age of 7 years, as documented in medical records. Pulmonary function was evaluated mainly by spirometry and multiple breath washout (MBW), whereas esophageal function was evaluated by 24-hour pH studies.

    RESULTS: We found a high prevalence of both respiratory (69%) and esophageal (62%) morbidity between birth and 7 years among the EA children. Examination with MBW (peripheral airway function) revealed few abnormal results, whereas spirometry revealed high airway obstruction in half the children, which also correlated well with overall respiratory symptoms (p = 0.047), as well as recurrent pneumonias (p = 0.035). However, no association with GER symptoms was found. In addition, 46% of the children had GER according to pH measurements, which were correlated to clinical GER symptoms but not to respiratory symptoms.

    CONCLUSION: This study confirms a high prevalence of respiratory and esophageal morbidity. In terms of respiratory function, the high proportion with a spirometric abnormality indicated an associated developmental delay/dysfunction in the central airways, whereas the peripheral airways appeared to have normal function at this age. Tracheomalacia may explain the spirometric abnormalities, but this need to be studied in more detail.

  • Sleep Stage Coordination of Respiration and Swallowing2016-06-26 11:22:18 AM
    A Preliminary Study.:

    Dysphagia. 2016 Jun ;

    Authors: Okuno K, Nohara K, Takai E, Sakai T, Fleetham JA, Ayas NT, Lowe AA, Almeida FR

    Abstract

    Swallowing is an important physiological response that protects the airway. Although aspiration during sleep may cause aspiration pneumonia, the mechanisms responsible have not yet been elucidated. We evaluated the coordination between respiration and swallowing by infusing water into the pharynx of healthy young adults during each sleep stage. Seven normal subjects participated in the study. During polysomnography recordings, to elicit a swallow we injected distilled water into the pharynx during the awake state and each sleep stage through a nasal catheter. We assessed swallow latency, swallow apnea time, the respiratory phase during a swallow, the number of swallows, and coughing. A total number of 79 swallows were recorded. The median swallow latency was significantly higher in stage 2 (10.05 s) and stage 3 (44.17 s) when compared to awake state (4.99 s). The swallow latency in stage 3 showed a very wide interquartile range. In two subjects, the result was predominantly prolonged compared to the other subjects. There was no significant difference in the swallow apnea time between sleep stages. The presence of inspiration after swallowing, repetitive swallowing, and coughing after swallowing was more frequent during sleep than when awake. This study suggests that the coordination between respiration and swallowing as a defense mechanism against aspiration was impaired during sleep. Our results supported physiologically the fact that healthy adult individuals aspirate pharyngeal secretions during sleep.

    Paraneoplastic Dermatomyositis Associated with Metastatic Seminoma.

    Case Rep Urol. 2016;2016:7050981

    Authors: Yoshie H, Nakazawa R, Usuba W, Kudo H, Sato Y, Sasaki H, Chikaraishi T

    Abstract

    We report the first case in Japan of paraneoplastic dermatomyositis with pure seminoma, a tumor that extremely rarely accompanies dermatomyositis. The patient presented to the hospital with muscle weakness and erythema and was diagnosed with dermatomyositis from skin biopsy. Routine radiological screening revealed testicular tumor and massive lymph node metastases. We initially performed orchiectomy along with conventional immunotherapy. However, muscle weakness gradually worsened, and he eventually showed dysphagia and forced respiration and became bedridden. Although he seemed close to being too unstable to tolerate further treatment, we started carefully adjusted chemotherapy comprising 4 courses of etoposide plus cisplatin, which proved highly successful. Lymph node metastases completely disappeared and swallowing and respiration fully normalized after completing chemotherapy. We believe that this clinical success was due to our decision to initiate chemotherapy even in such a weak patient.

  • Per-oral endoscopic myotomy (POEM)2016-06-26 11:22:18 AM
    Reduced postoperative pain scores and narcotic use favor per-oral endoscopic myotomy over laparoscopic Heller myotomy.:

    Surg Endosc. 2016 Jun ;

    Authors: Docimo S, Mathew A, Shope AJ, Winder JS, Haluck RS, Pauli EM

    Abstract

    INTRODUCTION: Per-oral endoscopic myotomy (POEM) is a less invasive therapy for achalasia with a shorter hospitalization but with similar short- and long-term outcomes as a laparoscopic Heller myotomy (LHM). Previous literature comparing POEM to LHM has focused primarily on postoperative outcome parameters such as complications, dysphagia scores and gastro-esophageal reflux severity. This study specifically compares postoperative pain following POEM to pain following LHM, the current gold-standard operation.

    METHODS: A retrospective review of all patients undergoing POEM or LHM for achalasia was performed from 2006 to 2015. Data collection included demographics, comorbidities, length of stay (LOS) and pain scores (arrival to the recovery room, 1 h postoperative, average first 24 h and upon discharge). Statistical analysis was performed using Student’s t test and Chi-square test.

    RESULTS: Forty-four POEM patients and 122 LHM patients were identified. The average age (52.2 ± 20.75 vs 50.9 ± 17.89 years, p = 0.306) and BMI (28.1 ± 7.62 vs 27.6 ± 7.07 kg/m(2), p = 0.824) did not differ between the POEM and LHM groups, respectively; however, the American Society of Anesthesiology scores were higher in the POEM patients (2.43 ± 0.62 vs 2.11 ± 0.71, p = 0.011). There were no differences in rates of smoking, diabetes, cardiac disease or pulmonary disease. The average pain scores upon arrival to the recovery room and 1 h postoperatively were lower in the POEM group (2.3 ± 3.014 vs 3.61 ± 3 0.418, p = 0.025 and 2.2 ± 2.579 vs 3.46 ± 3.063, p = 0.034, respectively). There was no difference in the average pain score over the first 24 h (2.7 ± 2.067 vs 3.29 ± 1.980, p = 0.472) or at the time of discharge (1.6 ± 2.420 vs 2.09 ± 2.157, p = 0.0657) between the POEM and LHM groups. After standardizing opioid administration against 10 mg of oral morphine, the POEM group used significantly less narcotics that the LHM group (35.8 vs 101.8 mg, p < 0.001) while hospitalized. The average LOS for the POEM group was 31.2 h and 55.79 for the LHM group (p < 0.0001). At discharge, fewer POEM patients required a prescription for a narcotic analgesic (6.81 vs 92.4 %, p < 0.0001).

    CONCLUSION: POEM demonstrated significantly less postoperative pain upon arrival to the recovery room and 1 h postoperatively. To achieve similar pain scores during the first 24 h and at discharge, LHM patients required more narcotic analgesic administration. Despite a significantly shorter LOS, fewer POEM patients require a prescription for narcotic analgesics compared to LHM. POEM is a less painful procedure for achalasia than LHM, permitting earlier hospital discharge with little need for home narcotic use.

  • RET protein is overexpressed in oral squamous cell carcinoma2016-06-26 11:22:18 AM
    Rearranged during transfection (RET) protein has been identified as a molecular therapeutic target in multiple types of cancer. Amongst these cancers are papillary thyroid, non-small cell lung (NSCLC), breast, pancreatic and prostate cancer, and tumours related to MEN2 syndrome.1 Tumours harboring RET oncogenic aberrations are successfully treated with various multikinase inhibitors in clinical setting, e.g. cabozantinib and vandetanib. RET oncogenic aberrations include RET protein overexpression, RET gene fusions, copy-number changes and RETpoint mutations.2

  • Patients with chronic cold urticaria may benefit from doxycycline therapy2016-06-26 11:22:18 AM

    Abstract

    Chronic cold urticaria (ColdU) is a rare but severe and potentially life-threatening form of chronic urticaria characterized by the development of wheal and flare type skin reactions or angioedema after skin exposure to cold1. Extensive cold contact (e.g. swimming in cold water) and low trigger thresholds (i.e. wheal responses to temperatures of 20°C or higher) may lead to systemic reactions including anaphylactic shock2.

    Retromolar foramen: an anatomical study with clinical considerations: The retromolar canal and foramen, an anatomical variation in the mandibular retromolar area, houses and transmits neurovascular elements that may innervate the mandibular third molar and associated tissues. These structures have been implicated in local anaesthetic failure, loss of sensation in the normal distribution of the buccal nerve, and local haemorrhage during surgery. Examination of 885 dry mandibles showed that 70 had a retromolar foramen (8%). There were no significant differences between groups according to age, sex, or ancestry.

  • Impact of midface and upper face fracture on bite force, mandibular mobility, and electromyographic activity2016-06-26 11:22:18 AM
    Impact of midface and upper face fracture on bite force, mandibular mobility, and electromyographic activity: This study evaluated the bite force, electromyographic activity, and mandibular mobility in patients undergoing surgery for facial fracture treatment that required a coronal approach. Ten men were divided into two groups: group I, coronal approach with pre-auricular extension (n=4, average age 34.5 years); group II, coronal approach (n=6, average age 24.8 years). The maximum bite force was measured using a dynamometer and mandibular mobility using a calliper. The electromyographic activity of the right masseter (RM), left masseter (LM), right temporal (RT), and left temporal (LT) muscles was evaluated using a Myosystem-Br1 apparatus.

  • Skin Pretreatment With Conventional Non-Fractional Ablative Lasers Promote the Transdermal Delivery of Tranexamic Acid2016-06-26 11:33:27 AM
    image
    BACKGROUND: Laser pretreatment of skin can be used to enable drugs used in dermatology to penetrate the skin to the depth necessary for their effect to take place.
    OBJECTIVE: To compare the permeation of tranexamic acid after conventional non-fractionated ablative Er:YAG and CO2 laser pretreatment in a laser-aided transdermal delivery system.
    MATERIALS AND METHODS: An erbium-doped yttrium aluminium garnet (Er:YAG) and a CO2 laser were used to pretreat dorsal porcine skin. Scanning electron microscopy was used to examine disruption of the skin surface. Confocal laser scanning microscopy was used to determine the depth of penetration of a reporter molecule (fluorescein isothiocyanate) into the skin. A Franz diffusion assembly was used to examine fluency-related increases in transdermal delivery of transexamic acid.
    RESULTS: Transdermal delivery of tranexamic acid increased as Er:YAG laser fluency increased. Transdermal delivery was higher when CO2 laser pretreatment was used than when Er:YAG laser pretreatment was used, but a “ceiling effect” was present and increasing the wattage did not cause a further increase in delivery. CO2 laser pretreatment also caused more extensive and deeper skin disruption than Er:YAG laser pretreatment.
    CONCLUSION: For conventional, non-fractionated ablative laser pretreatment, the Er:YAG laser would be an optimal choice to enhance transdermal penetration of transexamic acid.

    Continuous Wave Potassium Titanyl Phosphate Laser Treatment is Safe and Effective for Xanthelasma Palpebrarum: BACKGROUND: Although not an accepted standard treatment, the 532-nm continuous wave potassium titanyl phosphate (CW-KTP) laser might be a powerful device to treat xanthelasma palpebrarum (XP).
    OBJECTIVE: To determine the safety and efficacy of CW-KTP laser treatment for XP.
    MATERIALS AND METHODS: Between January 2013 and January 2015, 30 consecutive patients with XP were treated with a 532-nm CW-KTP laser (spot size: 0.9 mm, power: 5.0 W, fluence: 36–38 J/cm2, pulse width: 46 milliseconds, frequency: 2.0 Hz, passes per session: 3). In a retrospective study design, safety and efficacy data were collected and analyzed.
    RESULTS: Overall, 29/30 (97%) of patients had an excellent cosmetical result. Downtime was 1 week with crusted lesions. Although slight hypopigmentation was common, only 1/30 (3%) patients had hypopigmentation that was more than expected. Recurrences (13/30; 43%) were frequent, so that yearly maintenance therapy was warranted. No major side effects were noticed.
    CONCLUSION: Continuous wave KTP laser therapy is safe and highly effective for XP, although regular follow-up treatments are often necessary to maintain the achieved cosmetic results.

    OBJECTIVE: To review male facial anatomy, physiology, and behavior and how it contributes to sexual dimorphism in facial aging.
    METHODS: A MEDLINE search was performed for publications on gender differences in facial anatomy, aging, cutaneous physiology, and behavior.
    RESULTS: There are differences in both intrinsic and extrinsic aging factors in men. Men have a thicker epidermis and dermis with more active cutaneous appendages including hair growth. Male skin has a reduced antioxidant capacity and increased ultraviolet-induced immunosuppression. The male face is larger and has a unique square shape with less subcutaneous soft tissue, especially at the medial cheek. Men are also more prone to smoking and exhibiting poor sun-protective behavior. The differences in intrinsic and extrinsic aging factors contribute to poor facial aging in men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss.
    CONCLUSION: This review provides insight into the factors contributing to accelerated male facial aging. Understanding gender differences in aging will help physicians tailor cosmetic treatments for men and minimize extrinsic aging factors.
  • Triple combination therapy (TCT) with the active pharmaceutical ingredients hydroquinone 5%, tretinoin 0.03%, and dexamethasone 0.03% is often used for skin-lightening2016-06-26 11:20:36 AM
      imageBACKGROUND: Quality-switched (QS) laser therapy is a safe and well-established treatment option for removing solar lentigines. Triple combination therapy (TCT) with the active pharmaceutical ingredients hydroquinone 5%, tretinoin 0.03%, and dexamethasone 0.03% is often used for skin-lightening.
    OBJECTIVE: This prospective, open-label trial compares the efficacy and safety of a QS Ruby laser (QSRL) and a TCT in the treatment of solar lentigines.
    METHODS: In total, 15 patients with symmetrically distributed solar lentigines on the back of both hands were included. The lesions on the back of the right hand were treated in one or 2 sessions with a QSRL, the ones on the back of the left hand with a TCT for 7 weeks accompanied by UV protection. Clinical results were evaluated 4 weeks, 8 weeks, and 20 weeks after baseline.
    RESULTS: Treatment with QSRL provided significant lightening (p = .01) compared with TCT. Both procedures were generally well-tolerated. Comparing the side effects, the laser produced significantly more crusting and hyperpigmentation than the TCT.
    CONCLUSION: Both QSRL and TCT were capable in reducing solar lentigines in Fitzpatrick skin Type I to IV with an acceptable side effect profile. The QSRL provides faster, superior, and long lasting lightening compared with TCT.

  • Décolleté aging includes skin dyspigmentation, laxity, and visible wrinkling2016-06-26 11:20:02 AM
    Validated Assessment Scales for Décolleté Wrinkling and Pigmentation: BACKGROUND: Décolleté aging includes skin dyspigmentation, laxity, and visible wrinkling. The development of globally accepted scales for the assessment of décolleté aging is essential for aesthetic research and patient evaluation.
    OBJECTIVE: To develop a set of grading scales for the objective assessment of décolleté aging criteria and establish the reliability and validity of these scales.
    MATERIALS AND METHODS: To describe age-related changes to the décolleté, 3 photonumeric grading scales were created and validated: décolleté wrinkles—at rest, décolleté wrinkles—dynamic, and décolleté pigmentation—at rest. Thirteen aesthetic experts rated photographs of the décolleté of 50 women at rest and at dynamic “hand-to-elbow” positions in 2 validation sessions. Responses were analyzed to assess interrater and intrarater reliability.
    RESULTS: Interrater and intrarater reliability were both “almost perfect” (≥0.81, intraclass correlation coefficient and weighted kappa) for décolleté wrinkles—dynamic, summary score for décolleté, and estimated age. Reliability was “substantial” (0.61–0.80) for all other décolleté assessments. There was high correlation between all décolleté scales, estimated age, and estimated aesthetic treatment effort.
    CONCLUSION: Consistent outcomes between raters and by individual raters at different time points confirm the reliability of the décolleté grading scales, indicating that they will be a valuable tool for use in clinical research and practice.
  • Scalp Basal Cell Carcinoma2016-06-26 11:19:53 AM
    Review of 2,202 Cases: BACKGROUND: Increases in the incidence of basal cell carcinoma (BCC) in women, younger age groups and in aggressive scalp subtypes in younger women have been reported.
    OBJECTIVE: To describe lesion and patient characteristics in scalp BCC.
    MATERIALS AND METHODS: Retrospective audit of scalp BCCs from 3 pathology laboratories in Adelaide, South Australia, January 2009–December 2013.
    RESULTS: Scalp BCC was 2.6% of all BCC. Of 2,202 patients with scalp BCC, 62% were male and 78% were >60 years. Histologic subtypes included nodular (55%), mixed (30%), and superficial (8%). The concordance between biopsy and excision was 83% for division into nonaggressive and aggressive subtypes. The incomplete excision rate was 16%. Aggressive subtypes were larger and had perineural invasion (PNI) in 8.5% and incomplete excision in 26%.
    CONCLUSION: Basal cell carcinoma on the scalp was less common. Men and the elderly had the majority of cases, with no predilection for women, including aggressive histologic subtypes in younger women. Aggressive subtypes were associated with increased size, incomplete excision, and PNI. A preliminary biopsy assisted division into aggressive and nonaggressive histologic subtypes. Incomplete excision rates were higher and increased in aggressive histologic subtypes and PNI. Mohs surgery or wider margins are suggested in these cases.

    Human Foramen Magnum Area and Posterior Cranial Fossa Volume Growth in Relation to Cranial Base Synchondrosis Closure in the Course of Child Development.





    Abstract

    BACKGROUND: To date, no study has confronted the evolution of the foramen magnum area (FMA) and the posterior cranial fossa volume (PCFV) with the degree of cranial base synchondrosis ossification.
    OBJECTIVE: To illustrate these features in healthy children.
    METHODS: The FMA, the PCFV, and the ossification of 12 synchondroses according to the Madeline and Elster scale were retrospectively analyzed in 235 healthy children using millimeter slices on a computed tomography scan.
    RESULTS: The mean FMA of 6.49 cm2 in girls was significantly inferior to the FMA of 7.67 cm2 in boys (P < .001). In both sexes, the growth evolved in a 2-phase process, with a phase of rapid growth from birth to 3.75 years old (yo) followed by a phase of stabilization. In girls, the first phase was shorter (ending at 2.6 yo) than in boys (ending at 4.33 yo) and proceeded at a higher rate. PCFV was smaller in girls (P < .001) and displayed a biphasic pattern in the whole population, with a phase of rapid growth from birth to 3.58 yo followed by a phase of slow growth until 16 yo. In girls, the first phase was more active and shorter (ending at 2.67 yo) than in boys (ending at 4.5 yo). The posterior interoccipital synchondroses close first, followed by the anterior interoccipital and occipitomastoidal synchondroses, the lambdoid sutures simultaneously, then the petro-occipital and spheno-occipital synchondroses simultaneously.
    CONCLUSION: The data provide a chronology of synchondrosis closure. We showed that FMA and PCFV are constitutionally smaller in girls at birth (P <= .02) and suggest that a sex-related difference in the FMA is related to earlier closure of anterior interoccipital synchondroses in girls (P = .01).

  • Reversible Edema-Like Changes Along the Optic Tract Following Pipeline-Assisted Coiling of a Large Anterior Communicating Artery Aneurysm.2016-06-26 11:20:41 AM
    Reversible Edema-Like Changes Along the Optic Tract Following Pipeline-Assisted Coiling of a Large Anterior Communicating Artery Aneurysm.Aneurysmal volume expansion after endovascular treatment is caused by intra-aneurysmal thrombosis in the early postembolization period. Although postembolization mass effect on cranial nerves and other adjacent structures has been previously reported, we are unaware of reports involving the anterior visual pathway. A 66-year-old woman with a 2-week history of blurred vision without headache was found to have a large, unruptured anterior communicating artery aneurysm. One month after endovascular treatment of the aneurysm with coiling and flow diversion, the patient developed decreased vision in her right eye and a left homonymous hemianopia. Magnetic resonance imaging demonstrated compression of the right optic nerve, chiasm, and edema of the right optic tract. The patient was treated with a course of high dose corticosteroids, and over the course of several weeks, her vision improved and the optic tract edema resolved. We alert clinicians to this rare but potentially reversible visual complication of endovascular treatment of intracranial aneurysms.

    Congenital Tonic Pupils Associated With Congenital Central Hypoventilation Syndrome and Hirschsprung Disease.:Autonomic dysfunction can be associated with pupillary abnormalities. We describe a rare association of tonic pupils, congenital central hypoventilation syndrome, and Hirschsprung disease in a newborn with a mutation in the PHOX2B gene, a key regulator of neural crest cells. Hirschsprung disease is characterized by the congenital absence of neural crest-derived intrinsic ganglion cells. Tonic pupils may result from an abnormality of the ciliary ganglion, another structure of neural crest origin. The close association of these conditions in this child suggests a common abnormality in neural crest migration and differentiation.

    Neodymium-Doped Yttrium Aluminium Garnet Laser Treatment of Pediatric Venous Malformation in the Oral CavityimageBACKGROUND: Treatment of venous malformations in the orofacial region remains a challenge. Laser therapy is an alternative treatment in inoperable cases.

    OBJECTIVE: To retrospectively evaluate the effectiveness and complications associated with neodymium-doped yttrium aluminium garnet (Nd:YAG) laser treatment of oral venous malformations.

    MATERIALS AND METHODS: A total of 10 children (mean age: 7.3 years; range: 10 months-15 years) with oral venous malformation were treated with Nd:YAG laser during 2005 to 2013. Clinical improvement, including degree of color lightening and size reduction, and treatment complications, including dyspigmentation, textural change, and scarring were evaluated.

    RESULTS: Color clearing of 51% to 75% and >75% was seen in 25% and 45% of patients, respectively. Size reduction of 25% to 50%, 51% to 75%, and >75% was observed in 30%, 15%, and 45% of patients, respectively. Mild and moderate scarring was observed in 15% and 5% of cases, respectively.

    CONCLUSION: Nd:YAG laser is a promising alternative treatment in pediatric patients with inoperable venous malformations in the oral cavity. Mild to moderate scarring was the most common complication.

Thirteen aesthetic experts rated photographs of the décolleté of 50 women at rest and at dynamic “hand-to-elbow” positions in 2 validation sessions. Responses were analyzed to assess interrater and intrarater reliability.

    RESULTS: Interrater and intrarater reliability were both “almost perfect” (≥0.81, intraclass correlation coefficient and weighted kappa) for décolleté wrinkles—dynamic, summary score for décolleté, and estimated age. Reliability was “substantial” (0.61–0.80) for all other décolleté assessments. There was high correlation between all décolleté scales, estimated age, and estimated aesthetic treatment effort.

    CONCLUSION: Consistent outcomes between raters and by individual raters at different time points confirm the reliability of the décolleté grading scales, indicating that they will be a valuable tool for use in clinical research and practice.

  • Scalp Basal Cell Carcinoma2016-06-26 11:11:13 AM
    Review of 2,202 Cases: BACKGROUND: Increases in the incidence of basal cell carcinoma (BCC) in women, younger age groups and in aggressive scalp subtypes in younger women have been reported.

    OBJECTIVE: To describe lesion and patient characteristics in scalp BCC.

    MATERIALS AND METHODS: Retrospective audit of scalp BCCs from 3 pathology laboratories in Adelaide, South Australia, January 2009–December 2013.

    RESULTS: Scalp BCC was 2.6% of all BCC. Of 2,202 patients with scalp BCC, 62% were male and 78% were >60 years. Histologic subtypes included nodular (55%), mixed (30%), and superficial (8%). The concordance between biopsy and excision was 83% for division into nonaggressive and aggressive subtypes. The incomplete excision rate was 16%. Aggressive subtypes were larger and had perineural invasion (PNI) in 8.5% and incomplete excision in 26%.

    CONCLUSION: Basal cell carcinoma on the scalp was less common. Men and the elderly had the majority of cases, with no predilection for women, including aggressive histologic subtypes in younger women. Aggressive subtypes were associated with increased size, incomplete excision, and PNI. A preliminary biopsy assisted division into aggressive and nonaggressive histologic subtypes. Incomplete excision rates were higher and increased in aggressive histologic subtypes and PNI. Mohs surgery or wider margins are suggested in these cases.

    Invasive Squamous Cell Carcinoma: A Comparison of Tumors With or Without Horn Presentation Based on Age, Sex, Anatomic Site, Tumor Diameter, Depth of Invasion, and Grade of Differentiation in 1,666 Cases




    Abstract

    INTRODUCTION: Invasive squamous cell carcinoma (SCC) may present clinically with or without a horn.
    OBJECTIVE: To compare invasive SCC with or without horn presentation by anatomic site, tumor diameter, depth, and grade of differentiation.
    MATERIALS AND METHODS: The above characteristics of invasive SCC with or without horns were compared using a logistic regression model adjusted for potential confounders.
    RESULTS: There were 7.0% horns (n = 116) and 93.0% nonhorns (n = 1,550) in 1,666 cases. The median tumor diameter was 6 mm for horns, and 8 mm for nonhorn cases, p < .001. The median depth of invasion was 0.8 mm for horn cases and 1.3 mm for nonhorns, p < .001. Most cases were well-differentiated SCC for both horns (n = 102, 87.9%) and nonhorns (n = 1,265, 81.6%) p = .07. Horn cases had a borderline significant shift to well differentiation with moderate differentiation in 11.2% of cases (n = 13) and poor differentiation in 0.9% (n = 1).
    CONCLUSION: Horns presented on invasive SCC with reduced tumor diameters and reduced invasion depths compared to nonhorns. Horns presenting on invasive SCC were usually well differentiated. However, moderate and even poor differentiation can occur within a horn base.


  • Photodynamic Therapy2016-06-26 11:08:19 AM
     A Clinical Consensus Guide:

      imageBACKGROUND: The American Society of Dermatologic Surgery (ASDS) periodically develops consensus documents for its members concerning various aspects of dermatologic surgery. Advances in photodynamic therapy (PDT) have been many and PDT use has been established in a variety of skin conditions.

    OBJECTIVE: The ASDS board of directors proposed a committee of experts in the field to develop consensus documents on different treatments. An expert panel reviewed the literature on PDT and discussed the findings. The consensus was reached with evidence-based recommendations on different clinical applications for PDT.

    PATIENTS AND METHODS: This consensus document includes discussions regarding PDT, including different photosensitizers and various light source activators, historical perspective, mechanism of action, various therapeutic indications and expected outcomes, pre- and post-care, and management of adverse outcomes.

    RESULTS: Photodynamic therapy is highly effective for pre-cancerous lesions, superficial nonmelanoma skin cancers, inflammatory acne vulgaris and other conditions. New protocols including laser mediated PDT significantly improve results for several indications.

    CONCLUSION: The ASDS consensus document on PDT will be helpful for educating members on safe and effective PDT for a variety of indications.

Neck and shoulder pain is a common problem that affects a large number of people worldwide (Van Tulder et al., 2007). This problem is exacerbated by the escalating use of electronic devices such as smartphones and portable tablet computers (Berolo et al., 2011). The research concerning the etiology of chronic neck-shoulder pain has mainly focused on the study of muscle activation in the postural muscles such as cervical erector spinae (CES) and upper trapezius (UT) muscle (Visser and van Dieën 2006). from #ORL via xlomafota13 on Inoreader http://ift.tt/28T1FTR via IFTTT

Reversed cortical over-activity during movement imagination following neurofeedback treatment for central neuropathic pain

Αλέξανδρος ΣφακιανάκηςστοOtoRhinoLaryngology by Alexandros G.SfakianakisΠριν από 21 δευτερόλεπτα
Central neuropathic pain (CNP) is a frequent secondary consequence of spinal cord injury (SCI), affecting about 40% of patients (Siddall et al. 2003). Although CNP is caused by an injury to the somatosensory system (Haanpää et al. 2011) it can show first symptoms years after SCI. Neuroimaging studies have demonstrated changes in the resting state brain activity in the presence of CNP, which is reflected in increased thalamo-cortical coherence in the theta band (Stern et al. 2006, Sarnthein and Jeandmond 2008), as well as increased resting state EEG power and a dominant alpha frequ... περισσότερα »

A Formulation Study of 5-Aminolevulinic Encapsulated in DPPC Liposomes in Melanoma Treatment

Alexandros G. SfakianakisστοMelanoma by Alexandros G. SfakianakisΠριν από 4 ώρες
Photodynamic therapy (PDT) is a widely used technique for epithelial skin cancer treatment. 5-aminolevulinic acid (5-ALA) is a drug currently used for PDT and is a hydrophilic molecule at its physiological pH, and this limits its capacity to cross the stratum corneum of skin. Since skin penetration is a key factor in the efficacy of topical 5-ALA-mediated PDT, numerous strategies have been proposed to improve skin penetration. Yet this problem is still ongoing. The results of a previous study showed a low rate of 5-ALA encapsulated in liposomes (5.7%) that were 400 nm in size. In ... περισσότερα »
