Steps walked whilst at work, by University of the Free State medical registrars: an exploratory study

Background: Doctors may have physical disabilities affecting their mobility. If they wish to specialise, they need information regarding mobility requirements for various specialities to help them select an appropriate speciality. No research has been published on the differences in physical activity demands in different medical specialities. Objective: The aim of this study was to compare the physical activity of medical registrars from six specialist departments at a South African academic hospital. The inference was that those specialities where registrars walked the most would be more challenging for those with physical disabilities, thereby limiting mobility. Methods: The number of steps walked from 07:00 to 16:00 each day was measured, using Yamax CW-701 pedometers. Kruskall-Wallis tests were used to compare the steps taken in different specialities with the level of significance set at 0.05. Results: Twenty registrars participated in the study. Significant differences in the number of steps walked per day were observed between those from different specialities (p < 0.001). Surgery, paediatric and internal medicine registrars walked the most steps per day (median of 5 991, and 5 880, 5 489, respectively). Anaesthesiology and radiology registrars walked a median of 4 521 and 3 926 steps, respectively. Registrars in obstetrics and gynaecology walked the least steps (median of 1 918). There was considerable variation in steps between participants within a department, and for the same participants on different days. Conclusion: Registrars appeared to be more physically active in some medical specialities than others, in terms of mobility. The wide intra-speciality variation is probably related to differing daily duties. Future studies should include types of work duties (e.g. sedentary vs high physical mobility), cover more specialities, and include more participants.

The use of disinfection tunnels or disinfectant spraying of humans as a measure to reduce the spread of the SARS-CoV-2 virus

In endeavouring to mitigate the spread of the SARS-CoV-2 virus, a concerning practice of spraying individuals with disinfectant via so-called 'disinfection tunnels' has come to light. The Allergy Society of South Africa supports the World Health Organization in strongly condemning all human spraying, owing to lack of efficacy and potential dangers, especially to patients with coexisting allergic conditions

Tumours of the Chest in Children: A Review

Tumours of the chest in children constitute an array of pathology and clinical symptomatology. These tumours can be benign or malignant; cystic or solid; primary or as a result of secondary metastases. Collectively; tumours of the chest in children are very rare; the exact incidence of which is largely unknown globally. Non neoplastic lesions of the lung including bronchogenic cysts; sequestrations; congenital pulmonary airway malformations as well as infective and inflammatory disorders are 60 times more common than neoplastic causes.1 A tumour of the chest is considerably difficult to diagnose since patients can be asymptomatic for many years before symptoms evolve. Even more so; the symptoms are non-specific and can suggest more common and less sinister pathology. Clinically patients present with a variety of symptoms that depend largely on the location of the tumour.Airway tumours can be symptomatic or can present with chronic cough; wheeze; haemoptysis; atelectasis or persistent pneumonia. Secondary malignant parenchymal tumours are likely to be symptomatic from the primary lesion. Anterior mediastinal tumours can cause compression of the large airways or superior vena caval structures.It stands to reason that the physician needs to have a very high index of suspicion when dealing with these non-specific signs and symptoms. This article provides an approach to tumours of chest and reviews the common aetiology in the different compartments of the chest. The article will focus on common tumours of the airway; lung parenchyma; mediastinum; cardiac and chest wall pathology

Area characteristics and determinants of hospitalised childhood burn injury: a study in the city of Cape Town.

OBJECTIVES: To investigate the impact of local living circumstances on the level of childhood burn injuries. STUDY DESIGN/METHOD: This study was an ecological investigation encompassing the 634 residential areas of the city of Cape Town (about 668,900 children aged 12 years and younger). Fifteen socio-physical features of these areas that describe the population, household, dwelling types and services were considered using data from the 2001 census. Data of childhood burn injuries were gathered from the Red Cross Children's Hospital's register over 1999-2000 (n=923). Area features were synthesized into three main dimensions using factor analysis (principal axis method). Each dimension was split into three (exposure) levels, and the effect of each dimension on childhood burn injury was measured, compiling odds ratios with 95% confidence intervals and using the most favourable exposure level as the reference category within each dimension. RESULTS: The main dimensions of contextual exposure were defined as housing conditions (five variables), child dependency (three variables) and socio-economic barriers (three variables). Each aspect had a significant impact on the risk of burn injury, with increased levels of exposure leading to increased risk of burns. For housing conditions (Factor 1) and socio-economic barriers (Factor 3), a graded relationship was observed with noteably increased odds for increased levels of exposure. CONCLUSIONS: The occurrence of child burn injury is highly influenced by various features of the local environment. These features may be essential targets for sustainable childhood burn injury control and prevention programmes.
