Pattern of Isolated Fatal Mechanical Injury in Homicidal Deaths: A Cross-Sectional Study

Mechanical Injury among Medicolegal Cases in the Department of Emergency in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction

A medico-legal issue arises whenever an injured person visits a hospital. Therefore, all physicians who treat such patients have a legal duty to accurately document injuries as part of medical treatment. The study aimed to find out the prevalence of mechanical injury among medicolegal cases in the Department of Emergency in a tertiary care centre.

Methods

A descriptive cross-sectional study was conducted among patients admitted to the Emergency Department of a tertiary centre from May 2018 to April 2020 after obtaining ethical approval from the Institutional Review Committee (Reference number: 356). Convenience sampling method was used among patients who met the eligibility criteria. All relevant data were extracted using hospital records. Point estimate and 95% Confidence Interval were calculated.

Results

Out of 3486 medicolegal cases registered in the Department of Emergency, 856 (24.55%) (28.37-29.96 at 95% Confidence interval) were cases of mechanical injuries. Males 616 (71.96%) outnumbered females for all types of mechanical injuries. Road Traffic Accident 527 (61.56%) was the leading cause of injury and lacerations 351 (29.52%) were the most common pattern of injury. The majority 628 (73.36%) of the injuries were simple in nature.

Conclusions

The prevalence of mechanical injuries among medicolegal cases was similar in our study compared to other studies done in similar settings. The majority of the injuries were caused by traffic accidents, which could have been prevented if a safe system approach to road safety was followed.

Stem cells differentiation into insulin-producing cells (IPCs): recent advances and current challenges

Type 1 diabetes mellitus (T1D) is a chronic disease characterized by an autoimmune destruction of insulin-producing β-pancreatic cells. Although many advances have been achieved in T1D treatment, current therapy strategies are often unable to maintain perfect control of glycemic levels. Several studies are searching for new and improved methodologies for expansion of β-cell cultures in vitro to increase the supply of these cells for pancreatic islets replacement therapy. A promising approach consists of differentiation of stem cells into insulin-producing cells (IPCs) in sufficient number and functional status to be transplanted. Differentiation protocols have been designed using consecutive cytokines or signaling modulator treatments, at specific dosages, to activate or inhibit the main signaling pathways that control the differentiation of induced pluripotent stem cells (iPSCs) into pancreatic β-cells. Here, we provide an overview of the current approaches and achievements in obtaining stem cell-derived β-cells and the numerous challenges, which still need to be overcome to achieve this goal. Clinical translation of stem cells-derived β-cells for efficient maintenance of long-term euglycemia remains a major issue. Therefore, research efforts have been directed to the final steps of in vitro differentiation, aiming at production of functional and mature β-cells and integration of interdisciplinary fields to generate efficient cell therapy strategies capable of reversing the clinical outcome of T1D.
