BACKGROUND: The 2005 Bethesda Conference Guidelines advise patients with long QT syndrome against competitive sports. We assessed cardiac event rates during competitive and recreational sports, and daily activities among treated long QT syndrome patients. METHODS AND RESULTS: Long QT syndrome patients aged ≥4 years treated with anti-adrenergic therapy were included. Demographics included mechanism of presentation, corrected QT interval pretreatment, symptom history, medication compliance, and administration of QT-prolonging medications...

Lynch syndrome (LS) is an autosomal dominant disorder, with high penetrance that affects approximately 3% of the cases of colorectal cancer. Affected individuals inherit germline mutations in genes responsible for DNA mismatch repair, mainly at MSH2, MLH1, MSH6 and PMS2. The molecular screening of these individuals is frequently costly and time consuming due to the large size of these genes. In addition, PMS2 mutation detection is often a challenge because there are 16 different pseudogenes identified until now...

PURPOSE: To measure changes in the choroidal vascularity index (CVI) in chronic Vogt-Koyanagi-Harada (VKH) disease during a recurrent anterior uveitis attack. METHODS: Forty VKH patients and 40 normal controls were included in this study. Choroidal images were recorded before and during a recurrent anterior uveitis attack, as well as after appropriate treatment. CVI was measured by the binarization technique using ImageJ software (Bethesda, MD). RESULTS: The CVI was 0...

Objective: To evaluate the diagnostic efficacies of BRAF(V600E) testing and Bethesda system for reporting thyroid cytopathology (BSRTC) in thyroid nodules with thyroid imaging reporting and data system (TIRADS) category 4 and 5. Methods: A total of 187 thyroid nodules in 187 patients underwent the examinations of ultrasound-guided fine needle aspiration cytology (FNAC) and BRAF(V600E) mutation were analyzed retrospectively. Receive operating characteristic (ROC) curve was used to investigate the diagnostic values of both methods and the clinical application of BRAF(V600E) combined with BSRTC was evaluated...

BACKGROUND: The reclassification of noninvasive follicular variant of papillary thyroid carcinoma as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) has created diagnostic and management issues for thyroid fine-needle aspiration (FNA). In response to these challenges, the authors' laboratory adopted a NIFTP policy including 1) stringent criteria (requiring pseudo-inclusions, papillae, and/or psammoma bodies) for a malignant diagnosis of papillary carcinoma to limit false-positive results due to NIFTP and 2) the use of explanatory notes in cases with cytomorphologic features suggestive of possible NIFTP to encourage lobectomy over thyroidectomy...

Commensal organisms appear to play significant roles in normal homeostasis as well as in the pathogensis of HIV infection in a number of different organ systems. On November 17th and 18th 2016, leading researchers from around the world met to discuss their insights on advances in our understanding of HIV and the microbiome at the NIH in Bethesda.

OBJECTIVE: To explore the potential preoperative ultrasonography (US) and cytopathological features to avoid total thyroidectomy in NIFTP CONTEXT: Recently, it has been proposed that that non-invasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP) be classified as tumors, rather than cancer. PATIENTS: A total of 142 surgically proven follicular variant papillary thyroid carcinomas (FVPTCs; 45 NIFTP, 97 non-NIFTP; mean size: 20.4±11.0 mm, range: 10...

Background Retinal pigment epithelium (RPE) tears are a typical complication of vascular pigment epithelium detachment in age-related macular degeneration (AMD). During proactive intense anti-VEGF therapy, stabilisation or improvement of function may occur. With the new method of OCT angiography (OCT-A), retinal vessels and flow density can be quantified. This pilot study investigates changes in the choriocapillars (CC) in areas with increasing FAF in OCT following an RPE-tear. Methods In six eyes with an RPE-tear, prospectively initially and every three months thereafter, multimodal imaging was performed, including fundus autofluorescence (FAF) (HRA2, Heidelberg Engineering, Heidelberg, Deutschland) and OCT-A (RTVue XR Avanti, SSDA-Modus, Angiovue, Optovue, Freemont, CA, USA)...

INTRODUCTION: The vaginal flora of healthy adult women of reproductive age group constitutes predominantly Lactobacilli which inhibits the growth of other microorganisms (by maintaining acidic pH). The vaginal microflora is altered in favour of anaerobes in women using Intra Uterine Contraceptive Device (IUCD). Also, it can cause morphologic changes in both squamous and endocervical columnar cells. Similarly, the prevalence of vaginal lactobacilli is reduced among women using diaphragm-spermicide or spermicide alone...

OBJECTIVES: It is difficult to establish a diagnosis of the follicular variant of papillary thyroid carcinoma (PTC) using fine-needle aspiration cytology (FNAC). Preoperative features on ultrasound (US) imaging are different between follicular PTC and classic PTC. This study developed a risk score system to differentiate follicular PTC from classic PTC and to correlate the risk score of follicular PTC with its FNAC categories and pathologic features. METHODS: The US features, FNAC results, and pathologic reports of 156 follicular PTC nodules and 152 classic PTC nodules from 296 patients with PTC along with their clinical characteristics were reviewed retrospectively...

BACKGROUND: Genetic counselling and testing for Lynch syndrome (LS) have recently been introduced in several Latin America countries. We aimed to characterize the clinical, molecular and mismatch repair (MMR) variants spectrum of patients with suspected LS in Latin America. METHODS: Eleven LS hereditary cancer registries and 34 published LS databases were used to identify unrelated families that fulfilled the Amsterdam II (AMSII) criteria and/or the Bethesda guidelines or suggestive of a dominant colorectal (CRC) inheritance syndrome...

BACKGROUND: Persistent high-risk human papillomavirus (HR-HPV) infection is associated with the development of anogenital cancers, particularly in men living with HIV (MLWH). We describe the prevalence of anogenital HPV infection, abnormal anal cytology and anogenital warts (AGWs) in MLWH in Johannesburg, and explore whether HPV infection and receipt of antiretroviral treatment is associated with detection of abnormal anal cytology and AGWs. METHODS: We enrolled a cohort of 304 sexually-active MLWH ≥18 years, who completed a questionnaire and physical examination...

OBJECTIVE: To determine if the addition of an anterior superior iliac spine (ASIS) osteotomy to the lateral window, when combined with the anterior intrapelvic (AIP) surgical approach, would improve visualization of the iliopectineal eminence and allow for predictable and safe clamp application. METHODS: Ten lateral window approaches to the iliac fossa were developed in conjunction with the AIP approach on 10 fresh-frozen cadaveric pelvi. A calibrated digital image was taken from the surgeon's optimal viewing angle in order to capture the visualized osseous surface of the false pelvis with emphasis on the iliopectineal eminence...

Objectives: Reporting benign-appearing endometrial cells (nEMCs) in Papanicolaou (Pap) smears of women 40 years and older, introduced in The Bethesda System 2001, may be interpreted as an abnormal finding and lead to unnecessary endometrial biopsies. To our knowledge, this is the first study on the negative predictive value (NPV) of this cytology finding. Methods: An 11-year database with 1,036,629 Pap test reports and 121,079 surgical pathology reports identified reports of nEMCs in women 40 years and older with follow-up endometrial histopathology within 6 months...
