Background: Each year more than 10 million people worldwide are burned severely enough to require medical attention, with clinical outcomes noticeably worse in resource poor settings. Expert clinical advice on acute injuries can play a determinant role and there is a need for novel approaches that allow for timely access to advice. We developed an interactive mobile phone application that enables transfer of both patient data and pictures of a wound from the point-of-care to a remote burns expert who, in turn, provides advice back.

Introduction: Low and middle income countries bear a disproportionate burden of paediatric morbidity and mortality. South Africa, a middle income country, has unacceptably high mortality in children less than 5 years of age. Many factors that contribute to the child mortality rate are time sensitive and require efficient access to emergency care.

Introduction: Physician perceptions about emergency medical services (EMS) are important determinants of improving pre-hospital care for cardiac emergencies. No data exist on physician attitudes towards EMS care of patients with ST-Elevation Myocardial Infarction (STEMI) in the Emirate of Abu Dhabi.

Objectives: To describe the perceptions towards EMS among physicians caring for patients with STEMI in Abu Dhabi.

Purpose: Critically ill or injured children require prompt identification, rapid referral and quality emergency management. We undertook a study to evaluate the care pathway of critically ill or injured children to identify preventable failures in the care provided.

Methods: A year-long cohort study of critically ill and injured children was performed in Cape Town, South Africa, from first presentation to healthcare services until paediatric intensive care unit (PICU) admission or emergency department death, using expert panel review of medical records and caregiver interview.

Objective: To compare CPR performance in two groups of paramedics who received CPR training from two different CPR training programmes.

Methods: Conducted in June 2014 at the Hamad Medical Corporation Ambulance Service, the national ambulance service of the State of Qatar, the CPR performances of 149 new paramedic recruits were evaluated after they had received training from either a traditional CPR programme or a tailored CPR programme. Both programmes taught the same content but differed in the way in which this content was delivered to learners.

Objectives: We undertook this study in Kenya to understand the community's emergency care needs and barriers they face when trying to access care, and to seek community members' thoughts regarding high impact solutions to expand access to essential emergency services.

Design: We used a qualitative research methodology to conduct 59 focus groups with 528 total Kenyan community member participants. Data were coded, aggregated and analysed using the content analysis approach.

Article Synopsis
  • Aloe vera has a history of traditional medicinal use and can affect the absorption of drugs, including indinavir.
  • This study aimed to separate the polysaccharide components of Aloe vera gel by molecular weight to see how they impact the metabolism of indinavir.
  • Results showed that all Aloe vera fractions altered the drug's metabolism and bioavailability, but these effects were not linked to specific components like aloverose or the molecular weight of the fractions.

Due to their inherent phototoxicity and inevitable environmental release, titanium dioxide nanoparticles (nano-TiO2) are increasingly studied in the field of aquatic toxicology. One of the particular interests is the interactions between nano-TiO2 and natural organic matter (NOM). In this study, a series of experiments was conducted to study the impacts of Suwannee River natural organic matter (SRNOM) on phototoxicity and particle behaviors of nano-TiO2.

Objective: To conduct a systematic review of emergency care in low- and middle-income countries (LMICs).

Methods: We searched PubMed, CINAHL and World Health Organization (WHO) databases for reports describing facility-based emergency care and obtained unpublished data from a network of clinicians and researchers. We screened articles for inclusion based on their titles and abstracts in English or French.

Background: In 2011, the Department of Health of the Western Cape Province, South Africa, requested a review of current burn services in the province, with a view to formulating a more efficient and cost-effective service. This article considers the findings of the review and presents strategies to improve delivery of appropriate burn care at primary and secondary levels.

Methods: Surveys were conducted at eight rural and urban hospitals, two outreach workshops on burn care, four regional hospitals and at least 60 clinics in Cape Town and in the Western Cape as far as Ladismith.

Background: Response time is viewed as a key performance indicator in most emergency medical services (EMS) systems.

Objective: To determine the effect of increased emergency vehicle numbers on response time performance for priority 1 incidents in an urban EMS system in Cape Town, South Africa, using discrete-event computer simulation.

Method: A simulation model was created, based on input data from part of the EMS operations.

Following human gaze in dogs and human infants can be considered a socially facilitated orientation response, which in object choice tasks is modulated by human-given ostensive cues. Despite their similarities to human infants, and extensive skills in reading human cues in foraging contexts, no evidence that dogs follow gaze into distant space has been found. We re-examined this question, and additionally whether dogs' propensity to follow gaze was affected by age and/or training to pay attention to humans.
