ABSTRACT
Age-related changes in the lower eyelid are noticed by patients as bags or circles under the eye, a tired look, and a flattened face. Lower eyelid blepharoplasty, in which the excess skin and/or orbital fat is excised and repositioned, is mainly performed for aesthetic reasons rather than the correction of functional abnormalities. Favorable outcomes for the combination of these approaches have been reported, but the most suitable surgical technique is still debated. This systematic narrative review deals with the indications, preoperative considerations, operative techniques, and complications of several different surgical approaches to lower eyelid blepharoplasty.

AIMS: Considering individual variability in regards to the effects of orthokeratology (ortho-k) on myopia progression and controversies regarding the precise underlying mechanism, the aim of this study was to investigate several ocular measurements associated with axial length (AL) growth in children wearing ortho-k lenses. METHODS: In this retrospective chart review, medical records of 53 Chinese children who wore ortho-k lenses over the course of 12 months were reviewed. Baseline variables included age at initiation of ortho-k wear, refractive error (spherical equivalent, SE), central corneal thickness (CCT), and flat and steep keratometry of corneal principal meridians. The change of anterior chamber depth (ACD) and the change of crystalline lens thickness (CLT) between baseline and the 12-month follow-up were also analyzed. The contributions of all analyzed variables to AL change were assessed using univariate and multivariate regression analyses. RESULTS: Initially, the results of paired t-test showed that CLT and AL were significantly increased after 12 months of ortho-k wear compared with that at baseline (P = 0.001 and < 0.001). The ACD did not change significantly after 12 months compared with that at baseline (P = 0.491). Subsequently, univariate analyses showed that a reduced rate of AL elongation was found in children who were older age at initiation of ortho-k wear (P = 0.028), had greater SE (higher degree of myopia) at baseline (p = 0.006), had thicker CCT at baseline (P = 0.04), and had greater increase of CLT (P = 0.001) in 12 months. At last, only greater SE (higher degree of myopia) and greater increase of CLT were associated with smaller increases of AL in multivariable analyses, (P = 0.003 and 0.001). CONCLUSIONS: Both CLT and AL were significantly increased in children with overnight ortho-k wear after 12 months of follow-up. Greater baseline SE and greater increase of CLT were associated with less increase in AL during ortho-k wear in children with myopia.

BACKGROUND: Osteoarthritis (OA) is a debilitating disease process, affecting mobility and overall health of millions. Current treatment is for symptomatic relief and discovery of approaches to halt or reverse damage is imperative. Deletion of developmental endothelial locus-1 (Del1) has been shown to increase severity of OA in knockout mice. We examined the intracellular pathways involved in the ability of DEL1 to protect chondrocytes from apoptosis and anoikis and hypothesized that it functioned via integrin signaling. MATERIALS AND METHODS: Primary human chondrocytes were treated with various inducers of apoptosis, including anoikis, in the presence of added DEL1 or bovine serum albumin as control. Various inhibitors of integrin binding were examined for their effect on DEL1 activity. Downstream signaling pathway components were detected by immunoblotting. RESULTS: The addition of DEL1 protected chondrocytes from multiple inducers of apoptosis as measured by cell survival, terminal deoxynucleotidyl transferase dUTP nick end labeling and caspase 3/7 assays (P < 0.05). The effect of DEL1 was blocked by RGD peptides and by antibodies directed to integrin αVß3, but not by controls or antibody to integrin α1 (P < 0.05). Treatment with DEL1 promoted ERK and AKT activation when cells were attached, but only AKT activation under conditions of anoikis. CONCLUSIONS: DEL1 protected chondrocytes from apoptosis in response to activators of either the intrinsic or extrinsic pathways, and to anoikis. This effect was mediated primarily through integrin αVß3. This represents a therapeutic target for therapies to prevent cartilage degeneration in OA.

OBJECTIVE: Gender dysphoria is estimated to occur in over 1 million people in the United States. With decreasing stigma regarding the transgender population, it is likely more patients will seek medical and surgical gender transition as parts of their treatment. However, otolaryngologists may lack training in gender-confirming surgery. This study aims to determine the current state of transgender-related education in the United States otolaryngology training programs and to evaluate trainee perceptions regarding the importance of such training. METHODS: A cross-sectional survey was performed among the United States otolaryngology training programs. A representative sample of 22 training programs divided within 4 US Census regions completed a cross-sectional 9-question survey between March and May 2017. Respondents were queried regarding demographics, transgender curricular exposure (didactic and/or clinical), and perceived importance of training in transgender patient care. RESULTS: A total of 285 trainees responded (69.3% response rate). Thirty percent of respondents reported education on or direct exposure to transgender care during residency. Among those with experiences in gender-confirming surgery, more than half were exposed to facial (masculinization or feminization) or pitch alteration surgery. Overall, the majority of respondents believed training in gender-confirming surgery is somewhat important and 63.2% supported incorporation of transgender patient care in existing subspecialty fellowship training. CONCLUSION: Less than one-third of otolaryngology trainees are exposed to transgender patient care. The majority of trainees endorsed the importance of residency and subspecialty fellowship training in gender-confirming surgery. To better serve the transgender population, formal didactics on gender-confirming surgery should be offered.

OBJECTIVE: To compare the prevalence of disruptive behavior problems between preschool-aged children with hearing loss and normal hearing. STUDY DESIGN: Cross-sectional study. SETTING: Tertiary academic center. PATIENTS: Caregivers of children (2-5 yr old) with normal hearing (NH) (nâ=â39), hearing loss using hearing aid(s) (HA) (nâ=â29), or cochlear implant(s) (CI) (nâ=â21). INTERVENTION(S): Demographic information and a mental health history were obtained. Child behavior and language development were assessed. MAIN OUTCOME MEASURE(S): The Young Child-Diagnostic Interview Schedule for Children-IV and the MacArthur-Bates Communication Development Inventory III. RESULTS: Distributions of race, socioeconomic status, insurance status, and parental home situation (single versus two parent family) were similar across all groups. Parents of children with hearing loss were significantly more likely to report behavior problems (HAâ=â41%, CIâ=â38%) than parents of NH children (10%; pâ=â0.002). Children with hearing loss were significantly more likely to meet diagnostic criteria for oppositional defiant disorder (HAâ=â48%, CIâ=â48%) than NH children (23%; pâ=â0.02). More NH children (8%) than hearing impaired children (0%) had accessed mental health services (pâ=â0.08). NH children were found to have more advanced language development than hearing-impaired children (pâ<â0.01), but controlling for Communication Development Inventory III percentiles, the observed behavioral differences remained. CONCLUSION: Controlling for language development, children with hearing loss have higher prevalence of and impairment from disruptive behaviors than their NH peers. These children are less likely to receive appropriate behavioral interventions. Further research is warranted to investigate the impact of disruptive behaviors on speech and hearing rehabilitation. Methods to improve access to effective behavioral interventions in this population are needed.

OBJECTIVE: We identified significant expression of the matricellular protein, DEL1, in hypertrophic and mature cartilage during development. We hypothesized that this tissue-specific expression indicated a biological role for DEL1 in cartilage biology. METHODS: Del1 KO and WT mice had cartilage thickness evaluated by histomorphometry. Additional mice underwent medial meniscectomy to induce osteoarthritis, and were assayed at 1 week for apoptosis by TUNEL staining and at 8 weeks for histology and OA scoring. In vitro proliferation and apoptosis assays were performed on primary chondrocytes. RESULTS: Deletion of the Del1 gene led to decreased amounts of cartilage in the ears and knee joints in mice with otherwise normal skeletal morphology. Destabilization of the knee led to more severe OA compared to controls. In vitro, DEL1 blocked apoptosis in chondrocytes. CONCLUSION: Osteoarthritis is among the most prevalent diseases worldwide and increasing in incidence as our population ages. Initiation begins with an injury resulting in the release of inflammatory mediators. Excessive production of inflammatory mediators results in apoptosis of chondrocytes. Because of the limited ability of chondrocytes to regenerate, articular cartilage deteriorates leading to the clinical symptoms including severe pain and decreased mobility. No treatments effectively block the progression of OA. We propose that direct modulation of chondrocyte apoptosis is a key variable in the etiology of OA, and therapies aimed at preventing this important step represent a new class of regenerative medicine targets.

BACKGROUND: Facial feminization surgery encompasses a broad range of craniomaxillofacial surgical procedures designed to change masculine facial features into feminine features. The surgical principles of facial feminization surgery can be applied to male-to-female transsexuals and anyone desiring feminization of the face. Although the prevalence of these procedures is difficult to quantify, because of the rising prevalence of transgenderism (approximately one in 14,000 men) along with improved insurance coverage for gender-confirming surgery, surgeons versed in techniques, outcomes, and challenges of facial feminization surgery are needed. This review is designed to critically appraise the current facial feminization surgery literature. METHODS: A comprehensive literature search of the Medline, PubMed, and EMBASE databases was conducted for studies published through October of 2014 with multiple search terms related to facial feminization. Data on techniques, outcomes, complications, and patient satisfaction were collected. RESULTS: Fifteen articles were selected and reviewed from the 24 identified, all of which were either retrospective or case series/reports. Articles covered a variety of facial feminization procedures. A total of 1121 patients underwent facial feminization surgery, with seven complications reported, although many articles did not explicitly comment on complications. Satisfaction was high, although most studies did not use validated or quantified approaches to address satisfaction. CONCLUSIONS: Facial feminization surgery appears to be safe and satisfactory for patients. Further studies are required to better compare different techniques to more robustly establish best practices. Prospective studies and patient-reported outcomes are needed to establish quality-of-life outcomes for patients. However, based on these studies, it appears that facial feminization surgery is highly efficacious and beneficial to patients.

INTRODUCTION: The possibility of an HIV/AIDS epidemic in southeastern Europe (SEE) is not improbable. Thus, an understanding of the current issues surrounding HIV/AIDS care, specifically antiretroviral therapy (ART) adherence, in countries within SEE is critical. This study was conducted to determine the ART adherence characteristics of Albania's HIV-positive population. METHODOLOGY: This cross-sectional study reports initial demographic and adherence characteristics of patients receiving HIV/AIDS treatment in Albania. Retrospective review of pharmacy medications dispensed supplemented reported adherence behavior. Further, an adherence index was utilized to explore adherence more thoroughly. RESULTS: Patient-reported adherence and pharmacy review showed adherence levels of 98.9±4.4% and 97.7±4.7%, respectively. Assessment by adherence index revealed an index level of 91.7±6.7. Factors associated with a score of < 95 on the adherence index were: being partnered (OR = 0.29, 95% CI = 0.09 - 0.98), history of depression (OR = 0.24, 95% CI = 0.08 - 0.76), increased number of barriers to care (OR = 0.80, 95% CI = 0.66 - 0.97), and increased number of current social and medical needs (OR = 0.72, 95% CI = 0.58 - 0.91). CONCLUSIONS: Interventions aimed at reducing barriers to care, addressing current medical and social needs, and treating mental health issues may help improve adherence to ART in patients with HIV/AIDS in Albania. With little known about HIV/AIDS in SEE, this study provides guidance on how SEE countries can help prevent a possible rise in the prevalence of HIV given the close link of ART adherence and spread of HIV.

Though the HIV/AIDS epidemic in Southeastern Europe is one of low reported prevalence, numerous studies have described the pervasiveness of medical providers' lack of knowledge of HIV/AIDS in the Balkans. This study sought to culturally adapt an instrument to assess medical providers' knowledge of and attitudes towards HIV/AIDS in Albania. Cultural adaptation was completed through development of a survey from previously validated instruments, translation of the survey into Albanian, blinded back translation, expert committee review of the draft instrument, focus group pre-testing with community- and University Hospital Center of Tirana-based physicians and nurses, and test-retest reliability testing. Blinded back translation of the instrument supported the initial translation with slight changes to the idiomatic and conceptual equivalences. Focus group pre-testing generally supported the instrument, yet some experiential and idiomatic changes were implemented. Based on unweighted kappa and/or prevalence adjusted bias adjusted kappa (PABAK), 20 of the 43 questions were deemed statistically significant at kappa and/or PABAK ≥0.5, while 12 others did not cross zero on the 95% confidence interval for kappa, indicating their probable significance. Subsequently, an instrument to assess medical providers' knowledge of and attitudes toward HIV/AIDS for an Albanian population was developed which can be expanded within Albania and potentially to other countries within the Balkans, which have an Albanian-speaking population.

The transcriptome of ataxic muscles from alpha-tocopherol transfer protein deficient (ATTP-KO), 23-month old, mice was compared with that of their normal littermates. Genes encoding sarcolipin (sln) and ubiquitin carboxyl-terminal hydrolase (uchl1) were over-expressed (> or =10-fold) in ataxic muscles. SLN is a 3.2 kDa membrane protein that binds to sarcoplasmic reticulum calcium ATPase, regulates Ca(+ +) transport and muscle relaxation-contraction cycles. UCHL1 is a 24.8 kDa member of proteosome proteins; it is over-expressed in myofibrillar myopathy and is associated with neurodegenerative diseases. Furthermore, six additional transcripts, three encoding thin-filament proteins and three encoding Ca(+ +) sensing proteins that participate in contraction-relaxation cycle, and eight transcripts that encode members of lysosomal proteins were also over-expressed in ataxic muscles. These observations suggest that chronic alpha-tocopherol (AT) deficiency activates critical genes of muscle contractility and protein degradation pathways, simultaneously. The magnitude of induction of sln and uchl1 was lower in asymptomatic, 8-month old, ATTP-KO mice and in 8-month old mice fed an AT-depleted diet. These studies suggest sln and uchl1 genes as novel targets of AT deficiency and may offer molecular correlates of well documented descriptions of neuromuscular dysfunctions in AT-deficient rodents. Since the neuromuscular deficits of ATTP-KO mice appear to be similar to those of patients with ATTP mutations, it is suggested that over-expression of sln and uchl1 may also contribute to AT-sensitive ataxia in humans.
