The acceptability of insecticide treated mosquito nets among community members in Zimbabwe

A CAJM article on the advocacy of using treated mosquito nets in rural communities.Objectives: To assess the acceptability of insecticide treated mosquito nets (ITNs) among community members in Zimbabwe for the implementation of effective malaria intervention using ITNs. Design: A cross sectional study and longitudinal study were carried out using questionnaires, which were administered by health workers from rural health centres. Setting: Communities in rural areas from seven districts namely Bulilimamangwe, Chipinge, Gokwe, Hurungwe, Lupane, Mount Darwin and Uzumba Maramba Pfungwe (UMP) in Zimbabwe. Subjects: 1 576 community members who bought ITNs in the project areas. Main Outcome Measure: Acceptance of ITNs and price, reasons for wanting or not wanting nets; ITNs usage and washing pattern among respondents. Results: More than 90% of people said they bought the nets from the project in order to avoid mosquito bites and to prevent malaria. Quite a number of respondents (69%) gave the answer that they bought mosquito nets from the project because they were cheaper (Z$130 to Z$390) than the market price (Z$l 000) and more than half (58.3%) claimed that they could not afford to buy mosquito nets at the market price. The price was accepted by the majority as cheap or very cheap in Gokwe, Hurungwe, Mount Darwin, and UMP (92%, 82%, 98% and 90%, respectively). Other responses given for having bought nets were at health staff’ s-recommendation (71.3 %), and they were suffering from malaria (40.9%). The reasons for not having bought mosquito nets were that they had not suffered from malaria (55.5%), that they did not like to use a mosquito net (31.1%), did not know the efficacy of the net (21.6%), or there were not many mosquitoes at home (28.9%). The percentage of ITN use was very high (90 to 100%) amongst those who bought nets. The percentage of children under five years and pregnant women who were ITN users ranged from six to 24% to 2.8 to 9.7%, respectively. Percentage of “others” which means those above five years and not pregnant was more than 70% in all the districts. The washing pattern of ITNs in Chipinge showed that most of the mosquito nets (74.5%) were washed every three to five months. Conclusion: Acceptability of ITNs was very high based on reported utilisation of ITNs. It is recommended that rural communities should be sensitised on the importance of treated nets for malaria prevention, and advised to purchase mosquito nets whenever cash is readily available in each community

Giant Cell Arteritis Presenting as Small Bowel Infarction

Giant cell arteritis predominantly affects cranial arteries and rarely involves other sites. We report a patient who presented with small bowel obstruction because of infarction from mesenteric giant cell arteritis. She had an unusual cause of her obstruction and a rare manifestation of giant cell arteritis. In spite of aggressive therapy with steroids, she died a month later because of multiple complications. We discuss the diagnosis and management of small bowel obstruction and differential diagnosis of vasculitis of the gastrointestinal tract. We were able to find 11 cases of bowel involvement with giant cell arteritis in the English literature. This case report illustrates that giant cell arteritis can be a cause of small bowel obstruction and bowel infarction. In the proper clinical setting, vasculitides need to be considered early in the differential diagnosis when therapy may be most effective

Community coverage of an antimalarial combination of artesunate and amodiaquine in Makamba Province, Burundi, nine months after its introduction

BACKGROUND: In 2003, artesunate-amodiaquine (AS+AQ) was introduced as the new first-line treatment for uncomplicated malaria in Burundi. After confirmed diagnosis, treatment was delivered at subsidized prices in public health centres. Nine months after its implementation a study was carried out to assess whether children below five years of age with uncomplicated malaria were actually receiving AS+AQ. METHODS: A community-based study was conducted in Makamba province. Randomly selected households containing one or more children under five with reported fever onset within fourteen days before the study date were eligible. Case-management information was collected based on caregiver recall. A case definition of symptomatic malaria from observations of children presenting a confirmed malaria episode on the day of the survey was developed. Based on this definition, those children who had probable malaria among those with fever onset in the 14 days prior to the study were identified retrospectively. Treatment coverage with AS+AQ was then estimated among these probable malaria cases. RESULTS: Out of 195 children with fever on the day of the study, 92 were confirmed as true malaria cases and 103 tested negative. The combination of 'loss of appetite', 'sweating', 'shivering' and 'intermittent fever' yielded the highest possible positive predictive value, and was chosen as the case definition of malaria. Out of 526 children who had had fever 14 days prior to the survey, 165 (31.4%) were defined as probable malaria cases using this definition. Among them, 20 (14.1%) had been treated with AS+AQ, 10 with quinine (5%), 68 (41%) received non-malaria treatments, and 67 got traditional treatment or nothing (39.9%). Most people sought treatment from public health centres (23/99) followed by private clinics (15/99, 14.1%). The median price paid for AS+AQ was 0.5 US$. CONCLUSION: AS+AQ was the most common treatment for patients with probable malaria at public health centres, but coverage was low due to low health centre utilisation and apparently inappropriate prescribing. In addition, AS+AQ was given to patients at a price ten times higher than the subsidized price. The availability and proper use of ACTs should be monitored and maximized after their introduction in order to have a significant impact on the burden of malaria

Iron deficiency anaemia in adolescent athletes of the Vila Olímpica Fonndation of Manaus - AM

Considering the dearth of information with regard to the nutritional state of young athletes, were identified the prevalence of iron deficiency anaemia and its association with nutritional indicators of adolescent athletes participating in the Sport Initiation Program of the Vila Olímpica Foundation in Manaus -AM. A sample was made up of 194 voluntary adolescent male athletes classified as beginners, who participated in several different sports. Data collected was by verification of anthropometric measures (body weight, height, and skinfold thicknesses of triceps and subscapular skinfold), hemoglobin dosage utilizing a portable hemoglobinometer, HemoCue direct calorimetric method, and socioeconomic instrument. In the diagnosis of the nutritional states, we used Height-for-age- and Body Mass Index for the age indicators, adjusted cut-off points proposed by the WHO. The results showed that 9.4 % of the adolescents suffered from malnutrition, 8.2% overweight, and 4.6 obesity. The prevalence of iron deficiency anaemia found in the samples was 41.7%, with predominance in the lowest socioeconomic class. Although the prevalence of anaemia was high, the nutritional state of the adolescents did not influence these results, considering that the majority looked healthy. In view of these findings, we suggest that effective means be taken for nutritional education to minimize and/or control iron deficiency anaemia.Considerando a escassez de informações quanto ao estado nutricional de atletas jovens, identificou-se a prevalência de anemia ferropriva e sua associação com indicadores nutricionais de atletas adolescentes participantes do Programa de Iniciação Esportiva da Fundação Vila Olímpica de Manaus-AM. A amostra foi constituída por 194 atletas adolescentes do gênero masculino, voluntários, praticantes de diferentes modalidades esportivas classificados como iniciantes. A coleta dos dados foi realizada mediante verificação de medidas antropométricas (peso corporal, estatura e espessuras das dobras cutâneas tricipital e subescapular), dosagem de hemoglobina utilizando o hemoglobinômetro portátil (Sistema Hemocue) e instrumento socioeconômico. No diagnóstico do estado nutricional foram utilizados os indicadores Estatura para a Idade (E/I) e Índice de Massa Corporal para a idade (IMC/I), assumindo pontos de corte propostos pela OMS. Os resultados mostraram que 9,4% dos adolescentes apresentaram desnutrição, 8,2% sobrepeso e 4,6% obesidade. A prevalência de anemia ferropriva encontrada na amostra foi de 41,7%, com predominância na classe socioeconômica mais baixa. Embora a prevalência de anemia tenha sido elevada, o estado nutricional dos adolescentes não influenciou sobre este resultado, considerando que a maioria dos adolescentes apresentou-se eutrófica. Diante do exposto, sugere-se a adoção de medidas efetivas de intervenção e de educação nutricional visando à minimização e/ou o controle da anemia ferropriva
