Framingham risk assessment in Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with a known association with obesity [1]. Evidence of an association between metabolic syndrome and HS has been reported [2]. The Framingham Risk Score (FRS) [3] is a gender-specific algorithm used to estimate an individual's 10-year cardiovascular risk. Despite limitations of its use, it remains one of the most widely used risk assessment tools. Patients scoring less than 10% are considered to be at low risk, those between 10% and 20% are at moderate risk and those scoring 20% or more are considered to be at high risk.

Incidence of Facial Nerve Canal Dehiscence in Primary and Revision Cholesteatoma Surgery

Abstract

The aim of this retrospective study was to determine the incidence of facial canal dehiscence (FCD) in primary and revision cholesteatoma surgery in a tertiary referral center. Moreover, our second goal was to identify association between FCD and other intra-operative pathological findings in a group of patients with cholesteatoma surgery. Inclusion criteria were primary and revision canal wall up and canal wall down tympanomastoidectomy in patients who suffers from chronic otitis media (COM) with cholesteatoma. An exclusion criterion was charts with in adequate documentation. In addition tympanoplasty cases were excluded due to evaluate both tympanic and mastoid segments of facial nerve canal. Preoperative clinical data and intra-operative findings were documented in a formatted questionnaire. We found the incidence of FCD in COM surgery was 18%. There was no difference between the primary and revision surgeries regarding its incidence. In addition, there was association between some preoperative or intra-operative findings of COM, such as middle fossa dural dehiscence, external auditory canal polyp, facial nerve paralysis, labyrinthine fistula, and FCD. In conclusions we found that there was no difference between primary and revision surgeries regarding the incidence of FCD. Surgeons should consider effective measures to prevent intra-operative facial nerve trauma in COM surgeries.

The cosmetic and dermatological potential of keratin hydrolysate

Summary

Background

Although keratin hydrolysates have become established as standard components in hair and nail cosmetics, studies on the moisturizing effects of keratin hydrolysates do not appear among contemporary literature.

Objectives

To test if adding keratin hydrolysate into an ointment base increases hydration of the skin and improves skin barrier function, or diminishes trans-epidermal water loss.

Methods

Formulations were prepared containing 2%, 4%, and 6% keratin hydrolysates (based on weight of the ointment base). The moisturizing properties of keratin hydrolysates were tested by measuring skin hydration, trans-epidermal water loss and skin pH; measurements were carried out at intervals of 1, 2, 3, 4, 24, and 48 h. Testing was conducted on 10 women.

Results

As regards hydration, adding 2% keratin hydrolysate to the ointment base is optimal, as an increase of 14%-23% occurs in hydration of the stratum corneum. For trans-epidermal water loss, adding 4% KH to the ointment base is preferential, as this triggers a 26%-46% decrease in trans-epidermal water loss.

Conclusions

Keratin hydrolysate acts as a humectant (it binds water from lower layers of the epidermis to the stratum corneum) as well as an occlusive (it reduces trans-epidermal water loss). The highly favorable properties of keratin hydrolysates are attributed to the wide distribution of keratin hydrolysates molecular weights; low-molecular weight fractions easily penetrate the SC, while high-molecular weight fractions form a protective film on the epidermis. Adding keratin hydrolysates to the ointment base did not cause phase separation even after 6 mo storage.

Comparison of hair removal efficacy and side effect of neodymium:Yttrium-aluminum-garnet laser and intense pulsed light systems (18-month follow-up)

Summary

Background

Photothermal destruction of hair shaft melanin with intense pulsed light (IPL) and neodymium:yttrium-aluminum-garnet (Nd:YAG) laser has become an effective treatment of hair removal.

Aims

Our aim was to compare efficacy, satisfactory levels, safety, and side effects of Nd:YAG and IPL in hair reduction.

Methods

This was a prospective randomized intrapatient, right-left, assessor-blinded comparison of Nd:YAG vs IPL. There were 38 volunteers recruited. Seven sessions were performed. Hair count, efficacy, and side effects were compared before and after each treatment and 6 months after the last treatment. In respect of 12 volunteers, we have examined the reduction in hair after 18 months.

Results

Initially, there was no significant difference between the numbers of hair follicles. There was significant hair reduction after each treatment on the Nd:YAG-treated side. The hair reduction became significant after the third treatment with IPL. Comparison of the efficacy of the two devices on each visits showed no significant difference. There was statistically lower pain score on the IPL-treated side and statistically higher erythema, burning sensation, and edema on the Nd:YAG-treated side. Statistically lower side effect score was observed on the IPL-treated side. Eight months after the last treatment, there was significant hair reduction both on the Nd:YAG and on the IPL-treated side, and there was no difference between the efficacy. The patient satisfaction scores were higher with the IPL.

Conclusion

Unwanted hair can be reduced by both systems safely and effectively; however, IPL has less side effects and higher satisfaction scores.

Inclusion criteria were primary and revision canal wall up and canal wall down tympanomastoidectomy in patients who suffers from chronic otitis media (COM) with cholesteatoma. An exclusion criterion was charts with in adequate documentation. In addition tympanoplasty cases were excluded due to evaluate both tympanic and mastoid segments of facial nerve canal. Preoperative clinical data and intra-operative findings were documented in a formatted questionnaire. We found the incidence of FCD in COM surgery was 18%. There was no difference between the primary and revision surgeries regarding its incidence. In addition, there was association between some preoperative or intra-operative findings of COM, such as middle fossa dural dehiscence, external auditory canal polyp, facial nerve paralysis, labyrinthine fistula, and FCD. In conclusions we found that there was no difference between primary and revision surgeries regarding the incidence of FCD. Surgeons should consider effective measures to prevent intra-operative facial nerve trauma in COM surgeries.

Author(s): M. Pulido-Moran, P. Bullon, J.M. Morillo, M. Battino, J.L. Quiles, MCarmen Ramirez-Tortosa
ObjetiveTo examine the insulin resistance measured by surrogate indices in subjects with and without periodontitis and to find out any correlation among dietary intake with insulin resistance.DesignFifty-five patients were recruited to participate in this cross-sectional study. Insulin resistance measured by the homoeostasis model assessment (HOMA-IR) and the quantitative insulin sensitivity check index moreover glycaemia, creatinine, uric acid, high density lipoproteins, low density lipoproteins, very low density lipoproteins and triglycerides among others. True periodontal disease was elucidated through the examination of probing pocket depth, clinical attachment level, recession of the gingival margin and gingival bleeding. The statistical analyses used were the student's T-test for independent variables, Kolmogorov-Smirnov if variations were homogeneous; if not, the Mann-Whitney U Test was applied instead. Correlations between variables were assessed using Pearson's correlation coefficients. True periodontal disease was confirmed through the greater values of probing pocket depth, clinical attachment level, gingival margin and gingival bleeding in the periodontitis group in comparison with non-periodontitis group.ResultsInsulin resistance was evidenced by the greater values of HOMA-IR as well as by the lower quantitative insulin sensitivity check index values in the periodontitis group. Fasting insulin, glucose, uric acid, creatinine, low density lipoproteins, triglycerides and very low density lipoprotein levels were significant higher in periodontitis group. Pearson's correlations did not show any association among diet data and insulin resistance parameters in periodontitis patients.ConclusionA putative systemic relationship between insulin resistance and periodontitis exists but it does not seem conceivable any effect of diet over such relationship.

ObjectiveThis study aims to analyze the salivary peptidome/proteome of edentulous subject with respect to dentate control subjects.DesignUnstimulated whole saliva, collected from 11 edentulous subjects (age 60–76 years) and 11 dentate age-matched control subjects, was immediately treated with 0.2% aqueous trifluoroacetic acid and the acidic soluble fraction analyzed by High Performace Liquid Chromatography-Mass Spectrometry. The relative abundance of the salivary peptides/proteins was determined by measuring the area of the High Performace Liquid Chromatography-Mass Spectrometry eXtracted Ion Current peaks which is linearly proportional to peptide/protein concentration under identical experimental conditions. Levels of salivary peptides/proteins in the two groups were compared by the nonparametric Mann-Whitney test to evidence statistically significant differences.ResultsLevels of cystatin A, S-glutathionylated, S-cystenylated, S-S dimer derivatives of cystatin B and S-glutathionylated derivative of SPRR3, were found significantly higher in edentulous subjects with respect to dentate controls. The major peptides and proteins typically deriving from salivary glands did not show any statistically significant differences.ConclusionsCystatin A, S-glutathionylated, S-cystenylated, S-S dimer derivatives of cystatin B and S-glutathionylated derivative of SPRR3, which are mainly of intracellular origin and represent the major constituents of the cornified cell envelope are a clue of inflammation of mucosal epithelia.

Expression of odontogenic ameloblast-associated protein in the dental follicle and its role in osteogenic differentiation of dental follicle stem cells

Publication date: Available online 5 February 2017
Source:Archives of Oral Biology
Author(s): Shaomian Yao, Chunhong Li, Michael Beckley, Dawen Liu
ObjectiveOdontogenic Ameloblast-Associated Protein (ODAM) is encoded by a secretory calcium-binding phosphoprotein cluster gene, which generally plays an important role for mineralization. Dental follicle (DF) is essential in regulating bone formation for tooth eruption. This study aims to reveal ODAM expression in the DFs of developing and erupting molars, and to determine the possible role of ODAM.DesignDFs were collected from human third molars and rat mandibular molars for gene expression assessment and for establishment of cell cultures. RT-PCR and western blot were conducted to determine ODAM expression. Over- or silencing expression of ODAM in the dental follicle stem cells (DFSCs) was done by transfecting the cells with ODAM plasmid or siRNA to evaluate ODAM effects on osteogenesis.ResultsRat DFs weakly expressed ODAM at early-postnatal days, but a chronological increment of ODAM expression from days 1 to 11 was observed. Differences in expression of ODAM were seen in the human DFs of different individuals. In vitro, ODAM was expressed in DFSCs, but almost no expression in DF-derived fibroblast-like cells. Forcing the DFSCs to overexpress ODAM accelerated osteogenesis, whereas continuously silencing the ODAM in the DFSCs reduced osteogenesis only at 2 weeks of osteogenic induction.ConclusionsODAM is differentially expressed in the DFs of different age molars. Its expression is coincident with the increased bone formation of tooth crypt during tooth eruption in rat DFs. Increase of ODAM expression may accelerate osteogenic differentiation of DFSCs. Thus, ODAM expression in the DF may regulate bone formation for timely tooth eruption.

ObjectiveSaliva plays a pivotal role as an antioxidant system, and saliva antioxidant levels are reduced in patients with periodontal disease. Recently, a biochemical test able to determine saliva antioxidant levels was proposed as predictive for oral cavity diseases, but it was not clinically tested. In this preliminary study, we evaluated the relationships between Periodontal Screening and Recordings characteristics of patients and saliva antioxidant levels measures.DesignThirty-nine patients (12 men, 27 women; mean age, 46 years, SD 17) patients attending the dental hygiene unit of a Private Clinic underwent a Periodontal Screening and Recordings examination and a saliva antioxidant levels measurement using a biochemical commercial test. The results of the clinical periodontal examination were compared to those obtained by the saliva test.ResultsApproximately 70% of patients showed a low saliva antioxidant levels value, while the other patients had Optimal/Normal values. Thirteen patients (33%) resulted positive to Periodontal Screening and Recordings test. Using Periodontal Screening and Recordings values as gold standard, the saliva antioxidant levels test correctly classified 52.6% of patients; sensitivity was 84.6%, specificity was 36%.ConclusionsThe saliva antioxidant levels test had a good sensitivity when compared to the gold standard; this finding corroborates the hypothesis that alterations of the oral antioxidant levels are related to periodontal disease. The reduced specificity shows that saliva antioxidant levels test could detect alterations predisposing to periodontal disease before clinically evident aspects.

American Thyroid Association Awards Research Grant

Supported by ThyCa: Thyroid Cancer Survivors' Association, Inc. Research Grant to Trevor Angell, MD, Brigham and Women's Hospital and Harvard Medical School

The American Thyroid Association (ATA) has awarded 85 thyroid research grants totaling over $2.2 million since the inception of the Research Fund. In addition, the ATA rigorously manages the selection of research projects and distribution of over $1.8 million generously donated to the ATA specifically for research grants from ThyCa: Thyroid Cancer Survivors' Association, Inc. (ThyCa) and Bite Me Cancer.  For information on other research grants underway and funded by the ATA, see http://ift.tt/2l3TSGC.

The ATA has awarded a 2016 ThyCa Research Grant to Trevor Angell, MD, Instructor in the Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston MA, for his project entitled "Assessment of Circulation Immune Suppressor Cells for Predicating Treatment Response in Follicular Cell Derived Thyroid Carcinoma." The goal of this prospective study is to determine whether changes in the levels of myeloid derived suppressor cells (MDSC) in the peripheral blood of patients with thyroid cancer before and after therapy can serve as a predictive biomarker for response to treatment.

MDSCs are a type of immune cell that prevents the body's anti-tumor immune cells from doing their job and destroying cancer. Dr. Angell has proposed that MDSCs, which are rare in healthy individuals but tend to accumulate when cancer is present, can be used for personalized risk assessment and to monitor an individual's response to treatment in patients with papillary or anaplastic thyroid cancer. The ability to use changes in MDSC levels as a biomarker for disease progression and therapeutic drug response would give clinicians valuable information to guide treatment decisions.

Dr. Angell says, "After initial diagnosis and treatment for thyroid cancer, many patients worry about the possibility of residual cancer, cancer recurrence, or progression of their disease. Thanks to scientific investigators and organizations such as the American Thyroid Association, there have been tremendous advances in predicting the course of thyroid cancer, but there continue to be many cases with uncertainty. Novel method to provide individualized risk assessment would help clinicians and patients better understand and treat thyroid cancer. We are excited to investigate MDSC measurement as a promising biomarker for cancer behavior, and gratefully acknowledge both the ATA and ThyCa for providing essential research grants and being passionate advocates for scientific exploration, innovation, and improved patient care."

ThyCa: Thyroid Cancer Survivors' Association, Inc. has provided funding in support of 60 special research grants totaling $1,680,000 focused on thyroid cancer and medullary thyroid cancer since 2003. ThyCa supported three research grants in 2016 and three renewing grants; and plans are underway for similar support in 2017. ThyCa is a member of the ATA Alliance for Patient Education. Find out more at www.thyca.org.

Bite Me Cancer (BMC) is our newest grant funder supporting five thyroid cancer grants since 2014 for a total of $143,750. BMC will be supporting a new thyroid cancer grant in 2016 and one renewing grant. BMC is a member of the ATA Alliance for Patient Education. Find out more at www.bitemecancer.org.

PurposeImmunosuppressed solid organ transplant recipients (SOTRs) have an increased risk of developing cutaneous squamous cell carcinomas (cSCCs) with metastatic potential. This study sought to determine the rate of regional lymph node involvement in a large cohort of solid organ transplant patients with cutaneous head and neck squamous cell carcinoma.Materials and MethodsA retrospective chart review was performed on solid organ transplant patients with head and neck cutaneous squamous cell carcinoma treated at a tertiary academic medical center from 2005 to 2015.Results130 solid organ transplant patients underwent resection of 383 head and neck cutaneous squamous cell carcinomas. The average age of the patient was 63. Seven patients (5%) developed regional lymph node metastases (3 parotid, 4 cervical lymph nodes). The mean time from primary tumor resection to diagnosis of regional lymphatic disease was 6.7 months. Six of these patients underwent definitive surgical resection followed by adjuvant radiation; one patient underwent definitive chemoradiation. 6 of the 7 patients died of disease progression with a mean survival of 15 months. The average follow up time was 3 years (minimum 6 months).ConclusionsSolid organ transplant recipients with cutaneous squamous cell carcinoma of the head and neck develop regional lymph node metastasis at a rate of 5%. Regional lymph node metastasis in this population has a poor prognosis and requires aggressive management and surveillance.

Author(s): Nicholas L. Deep, Amy E. Glasgow, Elizabeth B. Habermann, Matthew L. Carlson
BackgroundPrimary melanoma of the external ear (PMEE) is rare and therefore well-suited for large population-based registry analysis. The objective of this study was to utilize the Surveillance, Epidemiology, and End Results (SEER) set of cancer registries to determine the incidence, treatment, and survival characteristics of PMEE.MethodsA retrospective cohort analysis of SEER data from 2004 to 2013 identified all cases of PMEE stage I-IV by AJCC 7th edition guidelines were extracted. Population-based incidence was calculated. Cancer-specific survival data by stage was assessed using Kaplan-Meier analysis and the relative effects of tumor characteristics were analyzed with Cox regression models.ResultsA total of 5481 patients were analyzed (mean age 66.7years, 86.5% male, 93.6% non-Hispanic white). The incidence of PMEE was 1.91 per 100,000 persons-per-year. At diagnosis, 68.1% were stage I, 15.2% were stage II, 4.7% were stage III, 1.5% were stage IV, and 10.8% were unknown. The five-year overall and cancer-specific survival was 78.8% and 90.0%, and, according to AJCC stage, was 85.7% and 95.3% for stage I (n=2287), 64.6% and 81.1% for stage II (n=453), 50.8% and 57.0% for stage III (n=154), 17.2% and 20.5% for stage IV (n=34), and 71.0% and 87.1% for unknown stage (n=330), respectively. The multivariable Cox model identified tumor characteristics that were independently associated with survival.ConclusionsThis is the first study to characterize the epidemiology, presentation and outcome of PMEE using the SEER registries. Older age, increasing Breslow thickness, stage, presence of ulceration, positive lymph nodes and distant metastasis each independently predicted time to cancer-specific death.

The objective of this systematic review was to examine the effect of orthognathic surgery (OS) on the temporomandibular joint and oral function. Electronic databases were systematically searched for studies published until October 2015. Articles were assessed against predefined inclusion criteria. The included papers were divided into four groups based on the type of OS performed. The following items were recorded: quality of evidence using the Oxford Centre for Evidence-Based medicine (CEBM) criteria, number of patients, presence/absence of controls, mean age at treatment, follow-up time, clinical examination findings, bite force, use of the Helkimo Index and Research Diagnostic Criteria for Temporomandibular Disorders, imaging findings, and patient questionnaire results. A total of 4669 articles were identified; 76 relevant articles were included in the review. These studies assessed a total 3399 patients and 380 controls, with a mean age of 25.4 years. The great variety of OS techniques, examination techniques, diagnostic criteria, and imaging techniques used in the articles studied, as well as the quality of the study designs, made it difficult to compare studies and to draw conclusions. However, looking at the different aspects studied in general, it can be stated that OS seems to have little or no harmful effect on the TMJ and oral function (level of evidence: levels II, III, and IV).

The objectives of this study were to evaluate the efficacy of additional cone beam computed tomography (CBCT) imaging on decreasing the risk of inferior alveolar nerve (IAN) injury during third molar removal in patients at high risk and to assess the surgical outcomes. The study sample included patients considered at high risk for IAN injury based on panoramic radiography (PAN) evaluation. The primary predictor was the type of imaging method (PAN only or with additional CBCT). The other variables were demographic and anatomical/radiographic factors. The primary outcome variable was IAN injury. The secondary outcome variables were the preoperative surgical plan and surgical results including IAN exposure and duration of surgery. The sample comprised 122 patients (139 teeth) aged 18–48 years. Postoperative temporary IAN injury was present in three (4.2%) cases in the CBCT group and 11 (16.4%) in the PAN group at 7 days after surgery. However, none of the patients had a permanent IAN injury at the 6-month follow-up. Additional CBCT imaging was not superior to PAN in reducing IAN injury after third molar surgery during long-term follow-up. Nonetheless, CBCT may decrease the prevalence of temporary IAN injury and improve the surgical outcomes in high-risk patients.

The effects on craniofacial growth of two different soft palate repair techniques in two-stage palatoplasty were investigated. This was a retrospective, cross-sectional cohort study of 68 children with non-syndromic, complete unilateral cleft lip and palate. Thirty-four patients were treated with the modified Furlow method (F-group) and the remaining 34 with the Widmaier–Perko method (P-group). Craniofacial growth was assessed by analyzing 12 angular and 12 linear measurements on lateral cephalograms. Composite facial diagrams from the two groups were compared with those of a control non-cleft group. Angular and linear measurements did not differ significantly between the two groups, implying that the craniofacial morphology was not affected by the difference in soft palate repair technique. However, small differences in anterior nasal spine and posterior nasal spine were found in cleft patients compared with controls. These findings suggest that the modified Furlow and Widmaier–Perko methods have a similar impact on craniofacial growth. Considering speech function, the modified Furlow method provides better craniofacial growth and speech function. However, the long-term effects of both methods on craniofacial growth after growth cessation remain to be determined.

Myopericarditis and Pericardial Effusion as the Initial Presentation of Systemic Lupus Erythematosus

Myopericarditis with a pericardial effusion as the initial presenting feature of SLE is uncommon. We report an unusual case of myopericarditis and pericardial effusion with subsequent heart failure, as the initial manifestation of SLE. The timely recognition and early steroid administration are imperative in SLE-related myopericarditis with cardiomyopathy to prevent the mortality associated with this condition.

Cooccurrence of Metastatic Papillary Thyroid Carcinoma and Salmonella Induced Neck Abscess in a Cervical Lymph Node

Cervical lymph node metastasis is common in patients with papillary thyroid carcinoma (PTC). Salmonella species are rarely reported as causative agents in focal infections of the head and neck. The cooccurrence of lymph node metastasis from PTC and a bacterial infection is rare. This report describes a 76-year-old woman with a cervical lymph node metastasis from PTC and Salmonella infection of the same lymph node. The patient presented with painful swelling in her left lateral neck region for 15 days, and neck ultrasonography and computed tomography showed a cystic mass along left levels II–IV. The cystic mass was suspected of being a metastatic lymph node; modified radical neck dissection was performed. Histopathological examination confirmed the presence of PTC in the resected node and laboratory examination of the combined abscess cavity confirmed the presence of Salmonella Typhi. Following antibiotic sensitivity testing of the cultured Salmonella Typhi, she was treated with proper antibiotics. Cystic lesions in lymph nodes with metastatic cancer may indicate the presence of cooccurring bacterial infection. Thus, culturing of specimen can be option to make accurate diagnosis and to provide proper postoperative management.
