Knowledge and practices of radiographers regarding infection control in radiology departments in Malawi.

INTRODUCTION: Adherence to standard infection control precautions (SICP) by radiographers is critical in combating healthcare associated infections (HAIs). Therefore, radiographers need to have adequate knowledge and practices of infection control if they are to contain the magnitude of HAIs. METHODS: Purposive, all-inclusive sampling was used to recruit 62 radiographers from four government referral hospital in Malawi. Radiographers' knowledge and practices of infection control were determined using a self-administered questionnaire. Data collection was carried out in January 2017. Descriptive (e.g. mean and standard deviation) and inferential (Chi2 test) statistics were generated using an MS Excel VBA application. RESULTS: The majority of the respondents (84%) were between 20 and 39 years of age. The study results revealed that radiographers in the four hospitals had mean infection control score (percentage) of 76.8 ± 12.6 for knowledge and a mean infection control score of 65.3 ± 16.1 for practice. A slight significant association between age and knowledge (p < 0.05; Cramer's V 0.26) was found in that radiographers between 40 and 59 years of age (majority of the sample) obtained higher knowledge scores than those 20-39 years of age. CONCLUSION: Given the results, further training is required regarding infection control among radiographers in radiology departments in Malawi. A guideline for infection control, specifically contextualised to be used by radiographers in radiology departments in Malawi, should be developed and implemented to enhance adherence to SICP in these departments.

Transverse colon volvulus in children: A case series and a review of the literature.

Volvulus of the transverse colon is very rare in children. Three cases that occurred in a short time span are described and the scarce literature is reviewed. All patients presented with colonic obstruction and in all three the condition was diagnosed at laparotomy, as CT-scanning is not an available option in either of the two institutions. The transverse colon had not become gangrenous but was resected after detorsion for redundancy. The postoperative course was complicated and relaparotomy had to be performed for reobstruction in all cases. Only if the 'reverse' bean sign is recognized on the preoperative plain abdominal radiograph this rare diagnosis can be suspected.

Chemical safety of cassava products in regions adopting cassava production and processing--experience from Southern Africa.

The cassava belt area in Southern Africa is experiencing an unforeseen surge in cassava production, processing and consumption. Little documentation exists on the effects of this surge on processing procedures, the prevailing levels of cyanogenic glucosides of products consumed and the levels of products commercially available on the market. Risk assessments disclose that effects harmful to the developing central nervous system (CNS) may be observed at a lower exposure than previously anticipated. We interviewed farmers in Zambia and Malawi about their cultivars, processing procedures and perceptions concerning cassava and chemical food safety. Chips, mixed biscuits and flour, procured from households and markets in three regions of Zambia (Luapula-North, Western and Southern) as well as products from the Northern, Central and Southern regions of Malawi, were analyzed for total cyanogenic potential (CNp). Processed products from Luapula showed a low CNp, <10 mg HCN equiv./kg air dried weight, while samples from Mongu, Western Province, exhibited high levels of CNp, varying from 50 to 290 mg HCN equiv./kg. Even the lowest level is five times higher than the recommended safety level of 10mg/kg decided on for cassava flour. Our results call for concerted efforts in promoting gender oriented processing technologies.
