Adult presentation of a rare mitochondrial tRNA Val gene mutation-an expanding clinical phenotype.

Background And Purpose: Late-onset mitochondrial disorders are diagnostically challenging with significant heterogeneity in disease presentation. A case is reported of a 67-year-old gentleman who presented with a 3-month history of seizures, recurrent encephalopathy, ataxia and weight loss, preceded by recent initiation of haemodialysis for end-stage chronic kidney disease.

Methods: Extensive work-up including serological, cerebrospinal fluid, magnetic resonance imaging and electroencephalography was performed.

Metastatic and locally aggressive BCC: Current treatment options.

The treatment of locally advanced and metastatic BCC presents a significant clinical challenge. Treatment options have evolved recently to include the use of hedgehog inhibitors Vismodigib and Sonidigib and immunotherapy with Cemiplimab.

The prognostic significance of nodal ratio on breast cancer recurrence and its potential for incorporation in a new prognostic index.

Axillary nodal status is an inherent part of prognostic tools such as the Nottingham Prognostic Index (NPI). Literature suggests that nodal ratio is a stronger predictive parameter than the total number of positive nodes sampled. Studies also note improved survival in node-negative patients with a larger proportion of nodes excised.

Hydrocolloid dressing in pediatric burns may decrease operative intervention rates.

Introduction: Partial-thickness scalds are the most common pediatric burn injury, and primary management consists of wound dressings to optimize the environment for reepithelialization. Operative intervention is reserved for burns that fail to heal using conservative methods. Worldwide, paraffin-based gauze (Jelonet) is the most common burn dressing; but literature suggests that it adheres to wounds and requires more frequent dressing change that may traumatize newly epithelialized surfaces.

Mesenchymal stem cell secretion of chemokines during differentiation into osteoblasts, and their potential role in mediating interactions with breast cancer cells.

Over 70% of patients with advanced breast cancer will develop bone metastases for which there is no cure. Mesenchymal Stem Cells (MSCs) and their derivative osteoblasts are subpopulations of cells within the bone marrow environment, postulated as potential interacting targets for disseminating cancer cells because of their ability to secrete a range of chemokines. This study aimed to investigate chemokine secretion throughout MSC differentiation into osteoblasts and their effect on the breast cancer cells.

Five years' experience of transverse groin incision for femoral artery access in arterial reconstructive surgery: parallel observational longitudinal group comparison study.

Vertical groin incisions (VGIs) have been used to access femoral vessels, but reports allude to wound complications. Our aim was to compare VGI with transverse groin incision (TGI) for femoral artery exposure. Over a 5-year interval, 196 patients with 284 femoral artery exposures for supra- and infrainguinal procedures were studied.
