Fatal tumour pulmonary embolism.

A 30-year-old female with no significant past medical history was referred to our facility with sudden onset of shortness of breath. She had a low clinical probability for pulmonary thromboembolism and a computed tomography angiogram showed enlarged pulmonary arteries but no in situ thrombi. She developed recurrent episodes of hypotension and hypoxia, and was transferred to the intensive care unit where she died despite active resuscitation.

Correlation of Mutations with Minimal Inhibitory Concentration of Rifampin and Rifabutin in in an HIV/AIDS Endemic Setting, South Africa.

Treatment of tuberculosis (TB) and HIV co-infections is often complicated by drug-to-drug interactions between anti-mycobacterial and anti-retroviral agents. Rifabutin (RFB) is an alternative to rifampin (RIF) for TB regimens and is recommended for HIV patients concurrently receiving protease inhibitors because of reduced induction of CYP3A4. This study sought to determine the proportion of RFB susceptible isolates among RIF-resistant strains in a high HIV prevalence setting in South Africa.

Additional Layers of Violence: The Intersections of Gender and Disability in the Violence Experiences of Women With Physical Disabilities in South Africa.

South Africa has unprecedented levels of violence and many South African women are exposed to violence during their lifetime. This article explores how gender and disability intersect in women's experiences of violence during their lifetime. Repeat in-depth qualitative interviews with 30 physically disabled women in Cape Town reveal that women with physical disabilities are exposed to various forms of violence, and shows how their impairments shape their violence experiences.

Comparison of the effectiveness of three retinal camera technologies for malarial retinopathy detection in Malawi.

The purpose of this study was to test the suitability of three available camera technologies (desktop, portable, and i-phone based) for imaging comatose children who presented with clinical symptoms of malaria. Ultimately, the results of the project would form the basis for a design of a future camera to screen for malaria retinopathy (MR) in a resource challenged environment. The desktop, portable, and i-phone based cameras were represented by the Topcon, Pictor Plus, and Peek cameras, respectively.

Anxiety Sensitivity in School Attending Youth: Exploratory and Confirmatory Factor Analysis of the 18-Item CASI in a Multicultural South African Sample.

Anxiety sensitivity (AS) is a risk factor for the development of anxiety disorders in youth. To date, the applicability of the Childhood Anxiety Sensitivity Index (CASI) in youth from a low or middle income country (LMIC) setting on the African continent has not been assessed. A representative sample of 1149 secondary school learners from 29 schools in Cape Town, South Africa, participated in the study.

Mediastinal granulomatous lymphadenitis in a population at risk for HIV and tuberculosis.

Background: Granulomatous inflammation on transbronchial needle aspirates from mediastinal lymph nodes is an infrequent yet important finding. We determined associations between cytomorphological features and underlying aetiology in an area of high prevalence of HIV-infection and tuberculosis.

Methods: We identified cases with granulomatous inflammation on mediastinal aspirates from January 2003 to July 2010.

Phosphoproteomics analysis of a clinical Mycobacterium tuberculosis Beijing isolate: expanding the mycobacterial phosphoproteome catalog.

Reversible protein phosphorylation, regulated by protein kinases and phosphatases, mediates a switch between protein activity and cellular pathways that contribute to a large number of cellular processes. The Mycobacterium tuberculosis genome encodes 11 Serine/Threonine kinases (STPKs) which show close homology to eukaryotic kinases. This study aimed to elucidate the phosphoproteomic landscape of a clinical isolate of M.

MT-CYB mutations in hypertrophic cardiomyopathy.

Mitochondrial dysfunction is a characteristic of heart failure. Mutations in mitochondrial DNA, particularly in MT-CYB coding for cytochrome B in complex III (CIII), have been associated with isolated hypertrophic cardiomyopathy (HCM). We hypothesized that MT-CYB mutations might play an important causal or modifying role in HCM.

Stents and stone disease.

The use of stents in renal stone disease is relatively new. The main advantage is reduced pressure in the renal collecting system during times of infected obstructed collecting systems, surgery or obstructing stones. As much pain relieve theses stents offer when indicated, equally much morbidity is caused when stent materials interface with the human urothelium in terms of symptoms, perforations and the "forgotten stent".

Volumetric structural magnetic resonance imaging findings in pediatric posttraumatic stress disorder and obsessive compulsive disorder: a systematic review.

Objectives: Structural magnetic resonance imaging (sMRI) studies of anxiety disorders in children and adolescents are limited. Posttraumatic stress disorder (PTSD) and obsessive compulsive disorder (OCD) have been best studied in this regard. We systematically reviewed structural neuroimaging findings in pediatric PTSD and OCD.

An evaluation of commercial fluorescent bead-based luminex cytokine assays.

The recent introduction of fluorescent bead-based technology, allowing the measurement of multiples analytes in a single 25-50 microl sample has revolutionized the study of cytokine responses. However, such multiplex approaches may compromise the ability of these assays to accurately measure actual cytokine levels. This study evaluates the performance of three commercially available multiplex cytokine fluorescent bead-based immunoassays (Bio-Rad's Cytokine 17-plex kit; LINCO Inc's 29-plex kit; and RnD System's Fluorokine-Multi Analyte Profiling (MAP) base kit A and B).

Pediatric anesthesia in developing countries.

Purpose Of Review: To highlight the problems faced in developing countries where healthcare resources are limited, with particular emphasis on pediatric anesthesia.

Recent Findings: The fact that very few publications address pediatric anesthesia in the developing world is not surprising given that most anesthetics are provided by nonphysicians, nurses or unqualified personnel. In compiling this article information is drawn from pediatric surgical, anesthetic and related texts.

Using two flaps to achieve aesthetic autologous breast mound reconstruction.

Breast mound reconstruction can be a particularly difficult procedure in patients who have delayed reconstruction. A technique in which two flaps are used is described. The lateral thoracodorsal flap is used to create a breast pocket, and the latissimus dorsi flap is used to fill this breast pocket.

Surface mapping of peripheral nerves in children with a nerve stimulator.

Defining anatomical landmarks may be difficult in the growing child. With the aid of a peripheral nerve stimulator, the path of many superficial peripheral nerves can be 'mapped' prior to skin penetration by stimulating the motor component of the peripheral nerve percutaneously with a 2-3.5 mA output.
