Article Synopsis
  • Post-mortem computed tomography (PMCT) is a valuable technique in forensic medicine for assessing head gunshot injuries, particularly through signs like vault bevelling to help identify entry and exit wounds.
  • A new study tested the cutaneous hyperdense rim sign, which could indicate entry wounds, showing high specificity (97%) but moderate sensitivity (63%) when analyzed in 64 cases of gunshot wounds.
  • The research found a significant correlation between the hyperdense rim sign and the presence of powder residues or bullet wipe, supporting its potential as an effective tool for determining gunshot entry wounds alongside other forensic methods.

Article Synopsis
  • Chronic kidney disease affects over 10% of the global population and significantly impacts the health and financial stability of those undergoing hemodialysis, especially in Ethiopia where research on predictors of survival time is limited.* -
  • A study conducted in Addis Ababa assessed the time to death and its predictors among 370 hemodialysis patients from 2017 to 2022, utilizing data analysis methods like Kaplan-Meier and Cox-proportional regression.* -
  • The results revealed a median survival time of 47 months, with age 64 and above, catheter vascular access, and cardiovascular disease identified as significant predictors of increased mortality risk in this patient group.*

Background: Female Genital Mutilation (FGM) is defined as any procedure that involves damage to the female external genitalia. This practice is majorly prevalent in Sudan, as it is estimated that over 12 million Sudanese women are circumcised. This study uncovers rural females' knowledge and insights about FGM domestically.

Success of psychosocial interventions in reducing aggressive challenging behaviour is likely to be related not only to mechanistic aspects but also to therapeutic and system factors. The study aims to examine the facilitators and barriers that influence whether psychosocial interventions for aggressive challenging behaviour in adults with intellectual disabilities lead to positive change. We conducted 42 semi-structured interviews with adults with intellectual disabilities who display aggressive challenging behaviour, family/paid carers, and professionals engaged in or delivering a psychosocial intervention across the UK.

Background: Intensive support teams (ISTs) are recommended for individuals with intellectual disabilities who display behaviours that challenge. However, there is currently little evidence about the clinical and cost-effectiveness of IST models operating in England.

Aims: To investigate the clinical and cost-effectiveness of IST models.

Background: Adults with intellectual disabilities often display behaviour that challenges that is a result of biological differences, psychological challenges, and lack of appropriate social support. Intensive Support Teams (IST) are recommended to support the care needs of this group and avoid hospitalisation. However, little attention has been paid to the perspectives of stakeholders who manage, work in, or use ISTs.

Background: Medication related problem (MRP) is an event occurring, as a result, the medication therapy that actually or potentially interferes with desired health outcomes. Evidences reported that the prevalence of MRPs may result in a high burden of morbidity and decrease patients' quality of life. The problem is more significant among patients with chronic kidney disease (CKD) as a decline in kidney function and increase number of medications required to treat kidney disease and its complications.

On the evening of November 13, 2015, the city of Paris and its surroundings was hit by a series of attacks committed by terrorist groups, using firearms and explosives. The final toll was 140 people deceased (130 victims and 10 terrorists or their relatives) and more than 413 injured, making these attacks the worst mass killings ever recorded in Paris in peacetime. This article presents the forensic operations carried out at the Medicolegal Institute of Paris (MLIP) following these attacks.

Corn, sorghum and wheat grains are used as livestock feed in the world. Identification of black aspergilli associated with these grains is necessary to make sure of the safety of the grains because its occurrence is an indicator of mycotoxin production. Forty-five isolates were isolated from the samples collected from Upper Egypt's markets and identified morphologically based on colony color, conidia, stipe and vesicle size and molecularly by using β-tubulin and calmodulin genes.

We encountered a 47-year-old woman, at 35 weeks of gestation, carrying triplets, who attended the hospital with severe pre-eclampsia and at admission had eclamptic fit followed by cardiac arrest. Cardiopulmonary resuscitation was started when she did not respond to initial measures; resuscitative hysterotomy was started on the site of collapse immediately, within 4 min postarrest, to deliver the triplets within 5 min postmaternal cardiac arrest. Timely decision of resuscitative hysterotomy done primarily to restore maternal cardiac output due to a grossly gravid uterus saved the mother and the triplets.

Introduction: The aim of this study was to assess the agreement between postmortem computed tomography (PMCT) and autopsy in detecting traumatic head injuries.

Materials And Methods: Consecutive cases of death that underwent both unenhanced PMCT and conventional autopsy were collected from our institution database during a period of 3 years and reviewed retrospectively. PMCT images were reviewed for the presence of fractures (cranial vault, skull base, facial bones and atlas/axis) and intracranial hemorrhage.

Background: Developing countries are now experiencing the epidemiologic transition, whereby the burden of chronic diseases, like metabolic syndrome, is increasing. However, no study had previously been conducted to show the status of metabolic syndrome among outpatients of Jimma University Teaching Hospital. Therefore, this study was designed to determine the prevalence of metabolic syndrome and associated factors among adult (≥20 years) patients.

The number of cases of acquired angioedema related to angiotensin converting enzyme inhibitors induced (ACEI-AAE) is on the increase, with a potential concomitant increase in life-threatening attacks of laryngeal edema. Our objective was to determine the main characteristics of ACEI-AAE attacks and, in doing so, the factors associated with likelihood of hospital admission from the emergency department (ED) after a visit for an attack.A prospective, multicenter, observational study (April 2012-December 2014) was conducted in EDs of 4 French hospitals in collaboration with emergency services (SAMU 93) and a reference center for bradykinin-mediated angioedema.

Background: Combination drug therapy is often used to achieve optimal analgesia in surgery. Paracetamol can be used as one component of an analgesic regime following hepatic resection.

Objective: This study was designed to investigate paracetamol and its metabolites by proton NMR spectroscopy in patient urine and to assess whether N-acetyl-p-benzoquinone imine (NAPQI, a hepatotoxic metabolite) formation is increased after liver resection.
