Article Synopsis
  • The study establishes reference values for the posterior tibial nerve (PTN) cross-sectional area (CSA) in South Africa to aid in diagnosing tarsal tunnel syndrome (TTS).
  • Ultrasound measurements were taken from 112 participants, and results showed that age and body mass index (BMI) significantly influence PTN measurements.
  • The recommended CSA reference value for normal PTN is set at 0.10 cm, applicable to all racial groups in South Africa, while suggesting that racial factors need further investigation.

Background: Schistosomiasis is a parasitic disease that is transmitted by skin contact with waterborne schistosome cercariae. Mass drug administration with praziquantel is an effective control method, but it cannot prevent reinfection if contact with cercariae infested water continues. Providing safe water for contact activities such as laundry and bathing can help to reduce transmission.

Background: An essential concept that all radiographers are required to implement is the use of techniques and the provision of protective devices to minimize radiation to patients and staff. Methods to achieve this could include good communication, immobilization, beam limitation, justification for radiation exposure, shielding, appropriate distances and optimum radiographic exposures factors.

Purpose: The aim of this study was to assess the availability and utilization of radiation protection and safety measures by medical imaging technologists (MITs) in Rwandan hospitals.

Introduction: Simulation based learning (SBL) has been used in diagnostic radiography for teaching and learning purposes. However, the method of offering the SBL opportunities has not been placed in the context of whether the experiences provide the student with a real life simulation. Moreover, in the light of the current staff shortages and healthcare issues in South Africa, placing students into the clinical practice without sound grounding in the application of theory into practice would be unfair to the student and patients.

A systematic review was performed to categorize the hERG (human ether-a-go-go-related gene) liability of antihistamines, antipsychotics, and anti-infectives and to compare it with current clinical risk of torsade de pointes (TdP). Eligible studies were hERG assays reporting half-minimal inhibitory concentrations (IC50). A "hERG safety margin" was calculated from the IC50 divided by the peak human plasma concentration (free C ).

Introduction: Spontaneous reporting systems (SRSs) are pivotal for signal detection, especially for rare events with a high drug-attributable component, such as torsade de pointes (TdP). Use of different national SRSs is rarely attempted because of inherent difficulties, but should be considered on the assumption that rare events are diluted in international databases.

Objective: The aim was to describe TdP-related events associated with antipsychotics, H1-antihistamines and anti-infectives in three national SRSs (in Italy, Germany and France) and highlight potential signals of torsadogenicity through a combined literature evaluation.
