Combined treatment with fractional carbon dioxide laser, autologous platelet-rich plasma, and narrow band ultraviolet B for vitiligo in different body sites: A prospective, randomized comparative trial

Summary

Background

Multiple treatment options are introduced in treatment of vitiligo but the response is unsatisfactory.

Objective

In this prospective, randomized, comparative trial, we studied the effect of combined treatment with fractional carbon dioxide (CO₂) laser, platelet-rich plasma (PRP) injection, and narrowband ultraviolet B (NB-UVB) for stable nonsegmental vitiligo regarding repigmentation grade, patient's satisfaction, and side effects.

Methods

Eighty adult patients with localized nonsegmental vitiligo were enrolled in this study. The patients were randomly categorized to receive 4 lines of treatment; fractional CO₂ laser, PRP, combined fractional CO₂ laser and PRP, and combined fractional CO₂ laser and NB-UVB. The treatment period was 2 months. Patients were clinically evaluated 3 months after the last treatment. Outcome was evaluated by 5-point scale for repigmentation, 10-point visual analog scale for patient's satisfaction, and side effects.

Results

Laser and PRP group achieved the best results regarding repigmentation and patient's satisfaction. Sixty percent of the patients developed repigmentation >50% and 40% of patients developed repigmentation >75%. In laser and NB-UVB group, 5% developed repigmentation >75% and 25% developed repigmentation >50%. Only 10% of patients developed repigmentation >75% in laser group and only 20% of patients developed repigmentation >75% in PRP group.

Conclusions

Combination of fractional CO₂ laser with PRP injection is a promising treatment for vitiligo, followed by combination of fractional CO₂ laser with NB-UVB phototherapy. Both fractional CO₂ laser and PRP injection gave poor results if they received alone.

Tubo-ovarian abscess infected by Salmonella typhi

We report a case of a tubo-ovarian abscess infected with Salmonella enterica serotype typhi. A 19-year-old Nepalese woman presented to a hospital in Kathmandu with lower abdominal pain, constipation, fever and a non-healing, suppurative surgical wound from an emergency caesarian section performed 2 months previously at 37 weeks of pregnancy. She also had an exploratory laparotomy for an appendix perforation with peritonitis at 25 weeks of gestation. Her wound infection did not respond to cloxacillin and she had an exploratory laparotomy, and a tubo-ovarian abscess was found from which S. typhi was isolated. She had a bilateral salpingo-oophorectomy and responded to 14 days of chloramphenicol. A tubo-ovarian abscess is a rare complication of enteric fever.

Solitary biceps muscle metastasis from breast cancer

Although direct muscle invasion by carcinoma is well recognised, skeletal muscle metastases are rare. Breast cancer very rarely metastasises to skeletal muscles. We present a case of breast cancer that metastasised to the biceps muscle. The woman developed breast cancer in 1990 and then developed axillary subcutaneous metastasis in 2001. In 2015, she presented with pain in the left forearm extending to the hand. Initial imaging showed no abnormalities, but the positron emission tomography-CT scanning revealed a hot spot in the left biceps muscle. Additionally, the nerve conduction study showed feature of carpal tunnel syndrome. The hot spot was deemed inconclusive in the view of normal CT and MRI scans, and the patient was treated with carpal tunnel decompression. A few months later, the patient developed a lump in the left biceps muscle, which appeared to be a metastatic lesion from her primary breast cancer. The patient was treated with radiotherapy and responded satisfactorily.

Topical ayurvedic ointment-induced chemical injury presenting as bilateral acute keratitis

A 40-years-old female patient was referred to the cornea clinic as a probable case of bilateral keratitis. The patient had a history of headache followed by acute onset of redness, pain and discharge from both eyes for 15 days. The patient was diagnosed as bilateral keratitis by the first contact physician and was started on topical antibiotics, cycloplegics and lubricating eye-drops. At presentation, both eyes had visual acuity of perception of light, conjunctival congestion, limbal blanching, diffuse corneal oedema and epithelial defect. A detailed history revealed application of Vicks VapoRub [topical ayurvedic analgesic which contains (per 100 g of product) menthol (2.82 g), camphor (5.25 g) and eucalyptol (1.49 mL) and excipients include thymol (0.1 g), turpentine oil (5.57 mL), nutmeg oil (0.54 mL), cedar wood oil and petrolatum)] on the forehead and eyelids for headache several times over 2–3 days before the onset. The patient further confirmed the accidental application of the ointment in the eyes. A provisional diagnosis of acute chemical injury with Vicks VapoRub was made and treatment with topical antibiotic, cycloplegic, steroid, lubricant and vitamin C was started. On follow-up, both eyes showed gradual resolution of corneal oedema and epithelial defect. Visual acuity improved in the left eye to 6/60 with no change in right eye due to corneal haze.

Vermiform appendix within incisional hernia

The vermiform appendix (whether inflamed or not) within a hernia is very rare occurrence. We present the unprecedented case of a normal appendix found within a Pfannenstiel incisional hernia. A diagnostic laparoscopy was performed as appendicitis was suspected. However, the tip of a normal appendix was visualised within a previous Pfannenstiel incision. Laparoscopic appendicectomy was carried successfully and the patient was discharged. The patient later returned for a successful elective laparoscopic incisional hernia repair.

Association of sickle cell haemoglobinopathies with dental and jaw bone abnormalities

Abstract

Objective

To estimate the association between sickle cell anaemia or trait with dental and jaw bone abnormalities.

Subjects And Methods

Subjects (n=369) were allocated to three groups: sickle cell anaemia, trait and control. Dental shape, number, size and position and changes in pulp chamber, root and periapex were analysed by intra-oral periapical radiographs. Integrity of lamina dura, quality of cancellous bone and bone trabeculation were also evaluated. Prevalence ratios (PR) were calculated (α=0.05).

Results

Sickle cell anaemia had higher prevalence (PR:8.31) and number of teeth (PR:13.40) with external resorption; higher number of teeth with pulp calcification; partial and total loss of lamina dura and higher prevalence of changes in trabecular structure of maxilla (PR:6.45) and mandible (PR:5.34). Sickle cell trait showed higher prevalence (PR:1.26) and higher number of teeth (PR:1.98) with partial loss of lamina dura; higher number of teeth with hypercementosis, changes in shape, size, periapex, total loss of lamina dura and higher prevalence of changes in mandibular trabecular bone (PR:1.43).

Conclusion

Pulp calcification and external resorption of the root were the most frequent dental alterations in sickle cell anaemia group, while in trait was higher frequency of changes in shape, size, periapex and root. Jaw bone changes were most prevalent in both homozygous and heterozygous subjects.

Genetic variants of microRNA processing genes and risk of non-syndromic orofacial clefts

Abstract

Objective

MicroRNAs (miRNAs) processing genes play important roles in the craniofacial development. The aim of the present study was to explore the associations between single nucleotide polymorphisms (SNPs) of miRNA processing genes with the risk of non-syndromic orofacial clefts (NSOC).

Methods

We genotyped 12 potentially functional SNPs from seven miRNA processing genes (GEMIN3, DROSHA, DGCR8, GEMIN4, PIWIL1, XPO5, and DICER) in a case-control study of 602 NSOC cases and 605 controls.

Results

Two SNPs were associated with the susceptibility of CL/P: rs10719 in DROSHA led to an increased risk of cleft lip with or without palate (CL/P) (GA/AA: P=0.024, OR=1.33, 95% CI=[1.04, 1.70]; GG+GA/AA: P=0.037, OR=1.29, 95% CI=[1.02, 1.63]), while rs493760 in DROSHA (CC/TT: P=0.049, OR=0.58, 95% CI=[0.34, 0.99]) could reduce the risk of CL/P. In addition, rs10719 (A)-rs493760 (C) haplotype contributed to a decreased risk of CL/P (OR=0.77, 95% CI=[0.63, 0.94]), whereas the rs10719 (G)-rs493760 (C) haplotype contributed to the increased risk of cleft palate only (CPO) (OR=2.70, 95% CI=[1.15, 6.35]). However, there was no difference observed in these SNPs after the Bonferroni correction.

Conclusion

Taken together, our results provided the potential evidence that rs10719 and rs493760 might contribute to the risk of CL/P, and suggested potential genetic basis and mechanisms of CL/P. The lack of association between these SNPs and CPO might be due to the limited sample size of CPO subgroup.

Susceptibility of partially-desalivated rats to erosive tooth wear by calcium-supplemented beverages

Abstract

Objectives

To investigate the susceptibility of partially-desalivated rats to erosive tooth wear (ETW); the anti-erosive effect of a calcium-supplemented beverage; and the quantification of ETW by micro-computed tomography (micro-CT).

Methods

The study population consisted of thirty-eight rats, divided into partially-desalivated (n=19) and normal salivary flow (n=19). They were randomly allocated into 3 subgroups (n=6-7): A-diet soda, B-diet soda+calcium, C-water (control). Solutions were provided ad-libitum for 28 days, and the rats were euthanized afterwards. Each left hemi-mandible was scanned using micro-CT for enamel volume (3 molars) calculation. Visual analysis of photographs of the lingual surface of 1^st molars was performed independently by 3 blinded examiners. Data were statistically analysed (α=0.05).

Results

Micro-CT revealed no significant differences between partially-desalivated or normal groups. Rats consuming A had more enamel loss than those consuming B or C, which did not differ from each other. For visual analysis, desalivation did not affect ETW. Rats consuming C showed the lowest ETW, followed by B and then A, for both partially-desalivated and normal rats. Spearman correlation between the two ETW quantification methods was -0.65.

Conclusions

Partial desalivation did not increase ETW. Ca-containing beverage prevented ETW. Micro-CT quantified ETW, although it was not as sensitive as visual analysis.

Cutaneous lupus erythematosus. Quality of life and related factors in a cohort of 260 patients of A Coruña, Spain

Abstract

Dermatological disease has a significant impact on quality of life (QoL). However, information is scarce for cutaneous lupus erythematosus (CLE) in this regard. Thus, the manifestation of and co-morbidities associated with CLE were assessed in the current study to determine factors predictive of QoL impairment. A descriptive cross-sectional study was performed on predominantly Caucasian patients with CLE, recruited at our institution between April 2013 and August 2016 (α = 0.050; precision ± 6.5%).

Comparison of pyoderma gangrenosum and hypertensive ischemic leg ulcer Martorell in a Swiss cohort

Abstract

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis presenting with painful and sterile skin ulcerations (1). Its aetiology remains largely unknown although an autoinflammatory background seems possible. Several comorbidities as well as triggering factors such as surgery, trauma or pharmacological therapies have been associated with the development of PG (2). Different topical and systemic treatments are recommended for PG, most commonly topical steroids or calcineurin inhibitors as well as systemic steroids, dapsone, infliximab and others, as well as by our group and others canakinumab and ustekinumab (3, 4).

PurposeCraniosynostosis may lead to hampered fetal head moulding and birth complications. To study the interaction between single suture craniosynostosis and delivery complications, an international, multicentre, retrospective cohort study was performed.Materials and MethodsAll infants born between 2006 and 2012 in the Netherlands and Sweden with sagittal or metopic suture synostosis were included. All births were included as a reference population. The primary outcome measure was rate of medically assisted labour. The secondary outcomes included method of conception, term of birth and fetal position.ResultsWe included 152 trigonocephaly patients, 272 scaphocephaly patients and 1.954.141 controls. A higher rate of assisted reproductive technology (ART) was found in patients with trigonocephaly (13%) and scaphocephaly (7%) compared to controls (3%, p<0.001). Scaphocephaly resulted in more postterm births (8% vs 4%, p<0.001). Trigonocephaly patients showed more preterm births (11% vs 6%, p<0.001), breech position was more frequent (10% vs 4%, p=0.003) and labour was more often induced. Rate of assisted delivery, including cesarean section, was significantly higher in both patient groups.ConclusionsScaphocephaly leads to more postterm births and an increased rate of cesarean sections. Trigonocephaly is related to ART, and in addition higher rates of breech position and cesarean section are found. Prenatal detection of single suture craniosynostosis could improve perinatal care.

Trends in antibiotic prescribing by dental practitioners in Germany

Publication date: Available online 19 August 2017
Source:Journal of Cranio-Maxillofacial Surgery
Author(s): Frank Halling, Andreas Neff, Paul Heymann, Thomas Ziebart
PurposeTo analyze the structure of antibiotic prescriptions by dentists in Germany during a time-period of four years in relation to medical antibiotic prescriptions.Materials and methodsWe collected nationwide data from all statutory health insurances on dental prescriptions of systemic antibiotics from 2012 to 2015. The annual reports of the "Research Institute for Local Health Care Systems" (WIdO, Berlin) provided the basis for this longitudinal data base analysis. The types of antibiotics, the number of prescriptions and the prescribed 'defined daily doses' (DDD) were analyzed. The results were compared to antibiotic prescriptions of German physicians.ResultsAn average of 8.8% per year of all antibiotic prescriptions are issued by dentists. The mostly prescribed antibiotic is amoxicillin. The share of amoxicillin on all dental prescriptions increased from 35.6% in 2012 to 45.8% in 2015 (p<0.01). About three-quarters of all dentally prescribed DDD can be attributed to amoxicillin and clindamycin. On the part of the physicians the proportion of clindamycin is 18fold lower than in the dental field.ConclusionsDental and medical antibiotic prescriptions in Germany show statistically significant differences regarding the shares of the prescribed antibiotics. In an international comparison the high proportion of Clindamycin in Germany is noticeable.

Author(s): Thiago Hoffman Jonasson, Rafael Zancan, Lucas de Azevedo Oliveira, Ana Claudia Fonseca, Marcela Claudino da Silva, Allan Fernando Giovanini, João Cesar Zielak, Melissa Rodrigues de Araujo
PurposeLow-level laser therapy (LLLT) can increase bone metabolism, cell proliferation, and maturation, and reduce inflammation, while platelet concentrate (PC) assists bone healing process by releasing proteins and growth factors. Here, we evaluated the efficacy of combined LLLT and PC therapy in the healing of critical-size bone defects.Materials and MethodsCalvarial critical-size defects 5 mm in diameter were made in 48 Wistar rats. Bones were removed, milled, and used as autogenous bone grafts. Animals were randomized into four groups: LP (LLLT+PC), PC, L (LLLT), and C (control, autogenous graft only). Animals were sacrificed at day 30 and 60 post-surgery. Specimens were submitted to radiographic (digital and conventional), histological, histomorphometric, and immunohistochemical analyses.ResultsDigital radiography was shown to be a better image analysis method compared with conventional radiography. Histological analysis demonstrated a significant difference in bone formation between animals in group L (p=0.049) at day 60 than in other groups. Higher rates of inflammatory infiltrates and fibrosis were observed in the LP and PC groups at days 30 and 60, whereas the groups not receiving PC showed a higher rate of bone maturity. The inflammatory processes were reduced in the animals in the L group, together with new bone formation and maturation. Groups L and C had higher scores of positive osteocalcin immunostaining in bone and extracellular matrix.ConclusionsLLLT reduces inflammation and contributes to increased bone formation. PC treatment was shown to maintain connective tissue and to induce fibrosis during bone repair. Combined LLLT and PC treatment did not improve bone repair.

Determining the fate of cranial sutures after surgical correction of non-syndromic craniosynostosis

Publication date: Available online 19 August 2017
Source:Journal of Cranio-Maxillofacial Surgery
Author(s): So Young Kim, Hyung-Jin Shi, So Young Lim
Purpose"Secondary craniosynostosis" (SCS) refers to a loss of sutures after corrective vault reconstruction. There are no prior studies that comprehensively review SCS in various types of non-syndromic craniosynostosis. We assessed idiopathic and iatrogenic SCS using 3-dimensional computed tomography (3D CT). We also performed a systematic review to estimate the overall incidence of SCS in each craniosynostosis type, and to characterize its clinical features.Materials and MethodsWe retrospectively reviewed the CT images of patients who underwent surgical correction of craniosynostosis for all types of craniosynostosis between August 1999 and December 2015. A literature search of the Medline and Ovid databases was conducted in October 2016 using the search term "secondary craniosynostosis."ResultsIn our series, iatrogenic SCS was observed in all patients who had manipulated normal patent sutures to variable extents. Three (17.6%) cases of idiopathic SCS developed on sagittal sutures, and were confirmed with a 12-month follow-up CT. In a pooled analysis of 10 articles, overall SCS developed in 123 of 1205 patients (10.2%). Iatrogenic SCS cases made up 87 of 1205 cases (7.2%), whereas 38 (3.1%) were idiopathic. Idiopathic SCS most commonly developed at the bi-coronal suture (n = 32, 84.2%), followed by the sagittal suture (n = 4, 10.5%) and uni-coronal suture (n = 1, 2.6%).ConclusionThis is the first review not only to describe SCS in all types of non-syndromic craniosynostosis, but also to classify SCS into iatrogenic and idiopathic types based on the underlying pathogenesis.

Regulatory T cell subsets in patients with medulloblastoma at diagnosis and during standard irradiation and chemotherapy (PBTC N-11)

Abstract

Background

We evaluated circulating levels of immunosuppressive regulatory T cells (T_regs) and other lymphocyte subsets in patients with newly diagnosed medulloblastoma (MBL) undergoing surgery compared to a control cohort of patients undergo craniectomy for correction of Chiari malformation (CM) and further determined the impact of standard irradiation and chemotherapy on this cell population.

Methods

Eligibility criteria for this biologic study included age 4–21 years, patients with CM undergoing craniectomy (as non-malignant surgical controls) and receiving dexamethasone for prevention of post-operative nausea, and those with newly diagnosed posterior fossa tumors (PFT) undergoing surgical resection and receiving dexamethasone as an anti-edema measure. Patients with confirmed MBL were also followed for longitudinal blood collection and analysis during radiotherapy and chemotherapy.

Results

A total of 54 subjects were enrolled on the study [22-CM, 18-MBL, and 14-PFT]. Absolute number and percentage T_regs (defined as CD4⁺CD25⁺FoxP3⁺CD127^low/−) at baseline were decreased in MBL and PFT compared to CM [p = 0.0016 and 0.001, respectively). Patients with MBL and PFT had significantly reduced overall CD4⁺ T cell count (p = 0.0014 and 0.0054, respectively) compared to those with CM. Radiation and chemotherapy treatment in patients with MBL reduced overall lymphocyte counts; however, within the CD4⁺ T cell compartment, T_regs increased during treatment but gradually declined post therapy.

Conclusions

Our results demonstrate that patients with MBL and PFT exhibit overall reduced CD4⁺ T cell counts at diagnosis but not an elevated proportion of T_regs. Standard treatment exacerbates lymphopenia in those with MBL while enriching for immunosuppressive T_regs over time.

Conidiobolomycosis: An Unusual Fungal Disease—Our Experience

Abstract

Conidiobolomycosis is a rare mycotic disease caused by Conidiobolus coronatus. Very few cases have been reported in English literature. Often it is clinically misdiagnosed as soft tissue tumour. A prospective case study was done from 2006 to 2015 in a tertiary care hospital of West Bengal, India. The objectives of our study were to describe the epidemiological and clinical features and treatment of Conidiobolomycosis to prevent disfigurement. Patients clinically suspected to be suffering from Conidiobolomycosis were subjected to biopsy followed by histopathological and mycological examinations. Then they were treated with oral saturated solution of potassium iodide along with other drugs. Total six cases were histopathologically proved to be suffering from Conidiobolomycosis. Fungus was isolated and identified in one case. Complete resolution was seen in five patients. Conidiobolomycosis should be brought into mind as differential diagnosis of subcutaneous swelling in the rhinofacial region.

A Successfully Treated Case of Gastrointestinal Stromal Tumor Causing Severe Anemia and Localized Peritonitis Showing Angina Pectoris Resulting in Watershed Cerebral Infarction

Ischemic stroke following acute myocardial infarction is a rare but a serious complication. Because the pathophysiology of stroke is dynamic, it is often hard to identify the cause of stroke. Here, we present the case of a 75-year-old man with ischemic stroke following angina pectoris caused by severe anemia and localized peritonitis due to gastrointestinal stromal tumor of small intestine. On admission, he showed consciousness disturbance, fever, and left hemiplegia. The electrocardiogram on admission showed ST-segment depression in V2 to V6 which was normalized 4 hours later. The ultrasound cardiogram showed the mild hypokinesis in the apical portion of left ventricle which was also normalized later. The magnetic resonance imaging and angiography showed ischemic stroke in watershed area between right anterior and middle cerebral arteries area and stenosis of distal portion of right middle cerebral artery. The computed tomography of abdomen showed a mass of small intestine. We decided to perform curative surgery after transfusion and successfully resected the mass of the small intestine, which was revealed to be a gastrointestinal stromal tumor (GIST). This is a successfully treated case of GIST in which the complicated pathophysiology of watershed cerebral infarction following angina pectoris might be clearly revealed.

Author(s): Sinan Uluyol, Omer Ugur, Ilker Burak Arslan, Ozlem Yagiz, Murat Gumussoy, Ibrahim Cukurova
IntroductionCanal wall down (CWD) tympanomastoidectomy is commonly used to treat advanced chronic otitis media or cholesteatoma. The advantages of CWD mastoidectomy are excellent exposure for disease eradication and postoperative control of residual disease; its disadvantages include the accumulation of debris requiring life-long otological maintenance and cleaning, continuous ear drainage, fungal cavity infections, and the occurrence of dizziness and vertigo by changing temperature or pressure.ObjectiveTo evaluate whether cavity-induced problems can be eliminated and patient comfort can be increased with mastoid cavity reconstruction.MethodsIn total, 11 patients who underwent mastoid cavity reconstruction between March 2013 and June 2013 comprised the study group, and 11 patients who had dry, epithelialized CWD cavities were recruited as the control group. The study examined three parameters: epithelial migration, air caloric testing, and the Glasgow Benefit Inventory (GBI). Epithelial migration, air caloric testing, and the GBI were studied in the study and control groups.ResultsThe epithelial migration rate was significantly faster in study group (1.63±0.5mm/week) than control group (0.94±0.37mm/week) (p=0.003, p<0.05). The mean slow component velocity of nystagmus of the study group (13.33±5.36°/s) was significantly lower when compared to control group (32.11±9.12°/s) (p=0.018). The overall GBI score was −7.21, and the general subscale, physical and social health scores were −9.71, −21.09, and +20.35, respectively in the control group. These were +33.93, +35.59, +33.31, and +29.61, respectively in the study group. All but the social health score improved significantly (0.007, 0.008, 0.018, and 0.181, respectively).ConclusionsCavity reconstruction improves epithelial migration, normalizes caloric responses and increases the quality of life. Thus, cavity rehabilitation eliminates open-cavity-induced problems by restoring the functional anatomy of the ear.

Hypermetabolic Thyroid Incidentaloma on Positron Emission Tomography: Review of Laboratory, Radiologic, and Pathologic Characteristics

Introduction. Incidental hypermetabolic thyroid lesions on Positron Emission Tomography have significant clinical value and may harbor malignancy. In this study we evaluated laboratory, radiologic, and pathologic characteristics of incidental hypermetabolic thyroid lesions. Materials and Methods. We evaluated 18 patients prospectively with various malignancies and hypermetabolic thyroid incidentaloma. The thyroid function tests, ultrasound assessment, and guided FNA biopsy were performed on all cases. Results. We included 9 male and 9 female patients with mean age of 51 years. Most common malignancy was colon cancer. Metabolic activity quantification using maximum standard uptake value demonstrated range between 1.4 and 65.4 with mean value of 9.4. We found highest metabolic activity in patients with lung adenocarcinoma, B-cell lymphoma, and colon adenocarcinoma. On ultrasound exam most thyroid lesions were of solid, hypoechoic, noncalcified nature with either normal or peripheral increased vascularity. FNA biopsy report was benign in 15 cases and malignant or highly suggestive for malignancy in 3 other cases. Two of the three malignant cases demonstrated metabolic activity higher than average SUV max. Conclusion. Most thyroid hypermetabolic incidentalomas are benign lesions, while higher values of SUV max are in favor of malignancy. This mandates further evaluation of incidentally found thyroid hypermetabolic lesions on routine PET/CT scans.

BackgroundIgG4-related disease (IgG4-RD) is a systemic fibro-inflammatory condition affecting various organs and has a diverse clinical presentation. Fibrosis and accumulation of IgG4+ plasma cells in tissue are hallmarks of the disease and IgG4-RD is associated with elevated IgG4 serum levels. However, disease pathogenesis is still unclear and these cellular and molecular parameters are neither sensitive nor specific for diagnosis of IgG4-RD.ObjectiveWe here sought to develop a flowcytometric gating strategy to reliably identify blood IgG4+ B-cells to study their cellular and molecular characteristics and investigate their contribution in disease pathogenesis.MethodsSixteen patients with histologically confirmed IgG4-RD, 11 patients with sarcoidosis and 30 healthy individuals were included for 11-color flowcytometric analysis of peripheral blood for IgG4-expressing B cells and T-helper (Th) subsets. In addition, detailed analysis of activation markers and chemokine receptors was performed on IgG4-expressing B cells and IgG4 transcripts were analyzed for somatic hypermutations.ResultsCellular and molecular analyses revealed increased numbers of blood IgG4+ memory B-cells in patients with IgG4-RD. These cells showed reduced expression of CD27 and CXCR5 and increased signs of antibody maturation. Furthermore, IgG4-RD patients, but not patients with sarcoidosis, had increased numbers of circulating plasma blasts and CD21^low B-cells, as well as Th2 and regulatory T-cells, indicating of a common disease pathogenesis in IgG4-RD.ConclusionThese results provide new insights into the dysregulated IgG4 response in patients with IgG4-RD. A specific "peripheral lymphocyte signature" observed in patients with IgG4-RD, could support diagnosis and treatment monitoring.

Granulomatosis with Polyangiitis with Myocarditis and Ventricular Tachycardia

Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a pulmonary-renal syndrome affecting small and medium sized blood vessels. The disease has a prevalence in studies ranging from 3 to 15.7 cases per 100,000, with a noted increasing incidence and prevalence in more recent studies. Pulmonary manifestations include hemorrhage, lung cavitary lesions, and pulmonary fibrosis. Within the kidney, GPA is known to cause rapidly progressive pauci-immune crescentic glomerulonephritis. Rare and severe cardiovascular manifestations include pericarditis, arrhythmias, myocarditis, and aortic valve disease. Our patient is a 43-year-old female with typical pulmonary and renal lesions from GPA and also acute myocarditis, multiple episodes of ventricular tachycardia, and a severe reactive thrombocytosis.

Manifestation of atopic dermatitis-like skin in TNCB-induced NC/Nga mice is ameliorated by topical treatment of substance P, possibly through blockade of allergic inflammation

Abstract

Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by intense pruritus and eczematous lesion. In this study, topically applied substance P (SP) significantly alleviated AD-like clinical symptoms in 2, 4, 6-trinitrochlorobenzene (TNCB)-induced dermatitis in NC/Nga mice. This effect was nullified by pre-treatment of the neurokinin-1 receptor (NK-1R) antagonist CP99994. SP treatment significantly reduced the infiltration of mast cells and CD3-positive T cells as well as inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and thymic stromal lymphopoietin (TSLP), in AD-like skin lesions and decreased the levels of IgE and thymus and activation-regulated chemokine in serum. This SP-induced alleviation of allergic inflammatory responses was also confirmed as reduced activation in the axillary lymph nodes (aLN) and spleen, suggesting the systemic effect of SP on immune responses in TNCB-induced NC/Nga mice. Furthermore, SP-mediated TSLP reduction was confirmed in human keratinocyte culture under pro-inflammatory TNF-α stimulation. Taken together, these results suggest that topically administered SP may have potential as a medication for atopic dermatitis.

Over-expression of p53 explains isotretinoin′s teratogenicity

Abstract

The precise molecular basis of retinoid embryopathy is yet unknown. This hypothesis predicts that isotretinoin (13-cis retinoic acid), the prodrug of all-trans retinoic acid (ATRA), exaggerates neural crest cell (NCC) apoptosis via upregulation of the pro-apoptotic transcription factor p53, the guardian of the genome. Increased p53 signaling is associated with Treacher Collins-, CHARGE-, and fetal alcohol syndrome, which exhibit dysmorphic craniofacial features resembling retinoid embryopathy. In addition, developmental studies of NCC homeostasis in the zebrafish support the pivotal role of p53. Translational evidence implies that isotretinoin-stimulated over-activation of p53 during embryogenesis represents the molecular basis of isotretinoin′s teratogenicity.

Regression of Diffuse B-cell Lymphoma of the Leg with Intralesional Gentian Violet

Abstract

In this case report, a patient of Primary Cutaneous Diffuse B-cell lymphoma, leg type was treated with intralesional gentian violet as she was judged to be too medically fragile for conventional chemotherapy due to advanced age and multiple serious comorbidities. Gentian violet (Crystal violet/ hexamethyl pararosaniline) is a triphenylmethane dye. It has been shown to have an inhibitory effect on NADPH oxidase, an enzyme family which is found in abundance in reactive oxygen driven tumors such as melanoma and lymphoma. We hypothesize that intralesional gentian violet treatment caused signaling changes in the lymphoma which allowed for immune clearance of the lymphoma. Complete resolution of the patient's lesion was noted on a follow up visit.

In vitro and in vivo models to investigate the pathomechanisms and novel treatments for pemphigoid diseases

Abstract

Pemphigoid diseases (PD) are a subgroup of rare acute or chronic autoimmune skin disorders characterized and caused by autoantibodies directed against distinct structural components of the dermal-epidermal junction. Binding of autoantibodies to their targets leads to the formation of blisters and erosions in patients. PDs comprise eight disorders for which the molecular target antigens have been identified. First, we review the available in vitro and ex vivo models for analysis of distinct aspects of the pathogenesis of PDs. This includes the binding of autoantibodies to skin sections, the analysis of blister formation capability and skin complement activation as well as investigation of neutrophil and keratinocyte activation. In addition to this, several animal models of PD have been developed during the last decades. These animal models have greatly contributed to our current understanding of the pathogenesis of PDs. We summarize spontaneously arising PD in animals and the induction of PD by transfer of (auto)-antibodies, transfer of (auto)-antigen specific lymphocytes and by immunization. In combined use, these models allow dissecting all aspects of PD pathogenesis, e.g. loss of tolerance, autoantibody production and inflammatory skin processes that lead to blister formation. Overall, we aim to foster translational biomedical research, to deepen our understanding of PD pathogenesis and to develop novel treatments for patients suffering from these life-threatening and difficult-to-treat autoimmune diseases.

Cytotoxic anti-melanoma drugs suppress the activation of M2 macrophages

Abstract

Together with regulatory T cells (Tregs), tumor-associated macrophages (TAMs) play roles in maintaining the tumor microenvironment. Though cytotoxic anti-melanoma drugs such as dacarbazine (DTIC), nimustine hydrochloride (ACNU), and vincristine (VCR) have been used for the treatment of malignant melanoma as adjuvant therapy in Japan, the detailed mechanisms of their immunomodulatory effects are not fully understood. Since the majority of TAMs are alternatively activated M2 macrophages that favor tumor development, the aim of this study was to elucidate the immunomodulatory effects of these reagents on human monocyte-derived M2 macrophages. First, mRNA expressions and protein production of immune checkpoint molecules, PD-L1, and chemokines by CD163⁺ CD206⁺ M2 macrophages derived from peripheral blood mononuclear cells were investigated to determine the immunomodulatory effects of DTIC, ACNU, and VCR. DTIC and VCR significantly decreased PD-L1 mRNA expression, which was confirmed by flow cytometry. Moreover, the mRNA expression and production of CCL22 were significantly decreased by DTIC, which suggested that DTIC might suppress the recruitment of Tregs in the tumor site. Furthermore, the decreased expression of PD-L1 and production of CCL22 were validated in vivo, using the B16F10 mouse melanoma model, leading to abrogation of the suppressive function of T cell proliferation. The present report suggests one of the possible anti-melanoma mechanisms of DAV combination chemotherapy for melanoma patients.

Eosinophils as putative therapeutic targets in bullous pemphigoid

Abstract

Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering skin disease and is characterized by the presence of autoantibodies directed against the hemidesmosomal proteins BP180 and BP230 that can be detected in the skin and serum of BP patients. Histologically, the dermal infiltration of eosinophils is obvious. The objective of this review is to present evidence that eosinophils play a key role in the pathogenesis of BP. Eosinophils, together with cytokines and chemokines regulating their production, recruitment and activation, are abundantly present in lesional skin, in blisters and in peripheral blood of patients with BP. Recently, using a cryosection model, eosinophils were demonstrated to induce dermal-epidermal separation in the presence of BP antibodies. Thus, eosinophils and their products, as well as mediators regulating their function, present promising targets for the treatment of BP.

Towards the development of a RNAi-based topical treatment for psoriasis: Proof-of-concept in a 3D psoriasis skin model

Abstract

RNA interference has emerged as a powerful tool for therapeutic gene silencing, as it offers the possibility to silence virtually any known pathology-causing gene. However, in vivo delivery of RNAi molecules is hampered by their unfavorable physicochemical characteristics and susceptibility to degradation by endogenous enzymes. To overcome these limitations, we recently developed an elastic liposomal formulation, called DDC642, as topical delivery system of therapeutic RNAi molecules for skin disorders. In this study, we validated the therapeutic efficacy of DDC642-encapsulated RNAi molecules in the treatment of psoriasis using three different in vitro models: a standardized keratinocyte monolayer culture, psoriasis-induced keratinocytes and a psoriasis reconstructed skin model. Four genes (IL22RA1, KRT17, DEFB4 and TSLP), known to be upregulated in psoriatic lesions, and thereby key players in psoriasis pathogenesis were selected. Moreover, the possibility of using a combined siRNA therapy in the topical treatment of psoriasis was explored. Results indicate a successful gene silencing of each different target, both at mRNA and protein level. Additionally, siRNA-DDC642 treatment resulted in a reduced expression of specific psoriasis markers, indicating their potential in future therapeutic approach. The examined siRNA combination (i.e. simultaneous knockdown of KRT17, DEFB4 and TSLP) showed an enhanced reduction in TSLP expression, whereas the decrease in K17 protein expression was impaired in psoriatic keratinocytes. Although the here examined siRNA combination could still be further improved, our study proved already in vitro the clinical potential of targeting multiple genes at once, each playing a different role in a complex disease such as psoriasis.

Profiling Cancer Risk in Oral Potentially Malignant Disorders – a Patient Cohort Study

Abstract

Background

Oral potentially malignant disorders harbour variable and unpredictable risk for squamous carcinoma development. Whilst current management strategies utilise histopathological diagnoses, dysplasia grading and targeted intervention for 'high risk' lesions, clinicians are unable to predict malignant potential.

Methods

Detailed, retrospective clinico-pathological analysis of potentially malignant lesions undergoing malignant transformation, from a 590 patient cohort treated by interventional laser surgery and followed for a mean of 7.3 years, was undertaken. Clinical outcome was documented at study census date (31 December 2014).

Results

99 patients (16.8%) developed cancer: 71 (12%) seen 'unexpectedly' upon excision and 28 (4.8%) progressing to malignancy at a median of 87.3 months post-surgery. 30 'unexpected' excisions were micro-invasive (42.3%) arising primarily in severely dysplastic precursors (75%) at ventro-lateral tongue and floor of mouth sites (54.5%); 1 patient (1.4%) had a cancer-related death, whilst 58 (81.7%) were disease free. 19 of 28 'progressive' cancers (67.9%) arose at new sites, with erythroleukoplakia a significant predictor of malignancy (p=0.0019). 9 (32.1%) developed at the same precursor site, with 6 (77.7%) on the ventro-lateral tongue and floor of mouth. 3 (10.7%) were micro-invasive, 9 patients (32.1%) died from metastatic disease and 12 (42.9%) were disease free (p<0.001).

Conclusion

Squamous carcinoma may arise at the site of a precursor lesion as transformation or new-site development via field cancerisation. Whilst interventional surgery facilitates early diagnosis and treatment of occult disease, thus reducing risk from same-site transformation, new-site cancer is a significant long-term risk for potentially malignant disorder patients.

Artepillin C as a targeting survivin molecule in oral squamous cell carcinoma cells in vitro: a preliminary study

Abstract

Background

Survivin, a member of the inhibitor of apoptosis family, is overexpressed in most human tumors, but undetectable in normal adult tissues. It is a promising target molecule in cancer treatment, since interference in its function promotes apoptosis. Artepillin C, a major, biologically active ingredient of Brazilian propolis, possesses anticancer activity against several cancer cells with different tissue origins. However, little is known about its bioactivity on oral squamous cell carcinoma cells or its effect on survivin expression. The aim of this study was to investigate the cytotoxic and anti-survivin activities of artepillin C in oral squamous cell carcinoma cells.

Methods

HSC-3 human oral squamous cell carcinoma cells were treated with varying doses of artepillin C for up to 72 hours. Cell viability was measured by WST-1, and the cytotoxic effects of artepillin C on HSC-3 cells were quantified with flow cytometry. The survivin levels were determined by ELISA.

Results

Artepillin C exhibited dose- and time-dependent cytotoxic effects on HSC-3 cells. Flow cytometric analysis showed that 22% of untreated HSC-3 cells underwent spontaneous cell death, whereas 77.32% of the cells were killed in response to the highest dose of artepillin C at 72 hours. Survivin expression was reduced in treated cells.

Conclusions

HSC-3 cells are vulnerable to artepillin C in a dose- and time-dependent manner. HSC-3 cell death induced by artepillin C, at least in part, was a result of a decrease in survivin levels.

Prelingual Deafness: An Overview of Treatment Outcome

Abstract

Prelingually deaf child is one who is either born deaf or who lost his or her hearing early in childhood, before acquiring language. A child with subnormal hearing acuity suffers from consequences of hearing loss compounded by impaired speech development. The period from birth to 3 years of life is critical for the development of speech and language, therefore, there is need for early identification and assessment of hearing loss and early rehabilitation in children. 40 patients were evaluated clinically, radiologically and audiologically to assess the degree of patient's handicap. The modes of treatment included use of hearing aid in patients with moderate, moderately-severe, severe or profound HL and cochlear implantation in patients with profound HL. Each patient was followed for 18 months and results were calculated in terms of speech perception (CAP) and language (REELS) development of the patient. Out of the 40 patients, 60% (n = 24) were females and 40% (16) were males. 50% (n = 20) patients had PSNHL, 32.5% (n = 13) had SSNHL, 10% (n = 4) had MSSNHL and 7.5% (n = 3) had MSNHL. 30% (n = 12) of patients had significant radiological findings. Among the hearing aid users patients with PSNHL got no benefit at the end of 18 months whereas the patients with cochlear implantation had significant improvement. Also the patients managed at a younger age (<3 years) had a significantly better outcome then those managed later. Early identification of hearing loss, that is followed by immediate and appropriate intervention results in better language, speech, and social-emotional development when compared to children treated at a later age.

Effect of a 12-methacryloyloxy-dodecyl-pyridinium-bromide–containing adhesive with different post types on the long-term bond strength to dentin

The use of matrix metalloproteinase (MMPs) inhibitors, such as 12-methacryloyloxy-dodecyl-pyridinium-bromide (MDPB), might improve the adhesion of glass-fiber (GF) and polyfiber (PF) posts to root dentine. This study assessed the effect of an MDPB-containing adhesive on the long-term bond strength of GF or PF posts to bovine dentine. Bovine endodontically treated roots were randomly divided into six groups, according to the post type and adhesive system used, as follows: GF serrated post + MDBP-free adhesive; GF serrated post + MDPB-containing adhesive; GF smooth post + MDBP-free adhesive; GF smooth post + MDPB-containing adhesive; PF post + MDBP-free adhesive; PF post + MDPB-containing adhesive. Specimens were stored in water for 6 months, thermocycled (500 cycles wk⁻¹), and submitted to the pull-out test and failure pattern analysis. The cement–dentin interface was evaluated using scanning electron microscopy. The pull-out data were analyzed using anova and Tukey's test (α = 0.05). No significant interaction between the type of post and the adhesive system was found. Polyfiber posts showed lower bond strength than GF posts, whether serrated or smooth, and the bond strength of the serrated and smooth GF posts was not significantly different. Adhesive failures were predominant in all groups. The type of retainer influenced the bond strength, and MDPB-containing adhesive did not improve the long-term bond strength of posts to dentine.

Author(s): Remzi Dogan, Erol Senturk, Orhan Ozturan, Yavuz Selim Yildirim, Selahattin Tugrul, Aysenur Meric Hafiz
ObjectiveThe aim of this study is to evaluate the effects of these two methods (Nasal corticosteroids (NCS) and radiofrequency (RF) application) on conchal contractility utilizing objective rhinologic measurement parameters.Methods82 patients were presented with the complaint of nasal obstruction and diagnosed with inferior turbinate hypertrophy and were included in the study. Patients in Group 1 received NCS for 12weeks. Patients in Group 2 were administered RF to their inferior turbinates. Acoustic rhinometry and rhinomanometry tests with and without decongestant were performed.ResultsIn the evaluation of the contractility difference of rhinometry parameters, there was not a significant difference among pre and postoperative acoustic rhinometric parameters in Group 1. Whereas in Group 2, postoperative contractility difference was significantly decreased compared to preoperative values.In the evaluation of the contractility difference of rhinomanometric parameters, no significant difference was found between pre and postoperative values in Group 1. However, postoperative contractility difference was significantly decreased compared to preoperative values in Group 2 in terms.ConclusionBecause the RF procedure produces fibrosis in the vascular tissues, inferior turbinates do not have a shrinking response to decongestant administration. Administration of NCS administration maintains the contractility function compared to RF application.
