Item The Role of Street Food Vendors in the Transmission of Enteric pathogens in Accra(Ghana Medical Journal, 1999-03) Mensah, P.; Owusu-Darko, K.; Yebooh-Manu, D.; Ablordey, A.; Nkrumah, F.K.; Kamiya, H.The role of street food vendors in the transmission of diarrhoeal pathogens was evaluated by assessing their knowledge on the definition of diarrhoea and transmission of diarrhoeal pathogens. Stool and blood cultures as well as the Widal test was carried to deter· mi ne their carrier status on a number of bacterial enteropathogens. All the vendors were female which emphasises the Important role women play in the provision of food through street food vending activities. They provide useful Service to the community by selling food to school children. market women, traders and workers. The level of education of these females was low and this reflected in their knowledge on the definition.. causes and transmission of enteric pathogens. Their personal hygiene was however good but the environment was often littered with garbage. A number of diarrhoeal pathogens were isolated from 66(37.5%) of these individuals. Salmonella '\P was isolated from 6(3.4%), Shigella from 2(1. 1%). Enteropathugenic E.coli (EPEC) from 59 (33.5%) and enteroaggressive E.coli (EPEC) from 34( 19.3%). Mixed enteric infection was common: seventeen had two different bacteria. Six had three and one had four different bacteria and another one had five. A total of 176 blood samples were cultured for bacteria and out of these only 1(0.6%) tested positive for Pasteurella gallinarium. In the Widal test only 153 serum samples were tested for antibodies to S typhi and 15(9.8%) titre of 1:80 to the somatic antigen. These were positive according to the manufacturers specifications but comparison with the stool and blood culture results showed that only one subject among this group actually had confirmed S typhi infection The screening of food handlers for enteric pathogens may be difficult to monitor SO food and personal hygiene education is recommended. Although the effectiveness of the Widal as a diagnostic tool for typhoidfever was not included in the initial objectives. the study showed that the Widal test cannot be used in isolation from laboratory results. This is even more difficult in the absence of a National Cut-Off Point. A survey to provide such data is also obviousItem Intrathecal chemoprophylaxis in the prevention of central nervous system relapse in burkitt's lymphoma(1985-07) Nkrumah, F.K.; Neequaye, J.E.; Biggar, R.A retrospective review of patients treated for endemic Burkitt's lymphoma in Ghana was undertaken to evaluate the efficacy of intrathecal (IT) chemoprophylaxis in preventing central nervous system (CNS) relapse. Patients treated before 1974 received no IT chemoprophylaxis and those treated between 1974 and 1979 received IT methotrexate in addition to systemic chemotherapy. In patients presenting with facial disease only (Stages I-II), there was no significant difference in the frequency of CNS relapse between those receiving IT chemoprophylaxis and those not receiving any. CNS relapse was, however, significantly reduced in patients presenting with abdominal disease (Stage III) who received IT chemoprophylaxis in addition to systemic combination therapy. This was associated with an improved survival.Item Use of buffy-coat smears in the diagnosis of septicaemia in children(1983-12) Nkrumah, F.K.; Neequaye, J.E.; Twum- Danso, K.Gram-stained buffy-coat smears from venous and capillary blood samples in 105 children suspected of septicaemia were examined for the presence of bacteria and the results compared with blood culture isolates. Gram-positive and Gram-negative bacteria were identified in 18 venous (44%) and 19 capillary (46%) buffy-coat preparations in 41 instances where bacterial organisms were isolated from the blood cultures. It is concluded that the examination of buffy-coat smears for bacteria in children suspected of septicaemia is a useful adjunct to blood cultures and, in areas where no facilities exist for culture of blood, may be a simple and rapid method of establishing the diagnosis of bacteraemia in suspected patients.Item A review of salmonella group G septicaemia in children at the korle bu teaching hospital (1973-1978).(1980) Neequaye, J.E.; Twum- Danso, K.; Nkrumah, F.K.Item Clinical features of Burkitt's lymphoma: The African experience.(IARC Scientific Publications, 1985) Nkrumah, F.K.; Olweny, C.L.Item Iron, folate and vitamin B12 in severe protein-energy malnutrition.(Central African Journal of Medicine, 1988) Nkrumah, F.K.; Nathoo, K.J.; Sanders, D.M.Item Aplastic anaemia in Zimbabweans.(Central African Journal of Medicine, 1987) Mukiibi, J.M.; Paul, B.; Nkrumah, F.K.Item The cytokine balance in severe malarial anemia [5] (multiple letters).(Journal of Infectious Diseases, 1999) Kurtzhals, J.A.L.; Akanmori, B.D.; Quarm Goka, B.; Adabayeri, V.; Nkrumah, F.K.; Behr, C.; Hviid, L.; Othoro, C.; Udhayakumar, V.Item Fever in Africa and WHO recommendation.(Lancet, 1997) Dunyo, S.K.; Koram, K.A.; Nkrumah, F.K.Item A longitudinal study of malaria infection, morbidity and antibody titres in infants of a rural community in Ghana.(Transactions of the Royal Society of Tropical Medicine and Hygiene, 1995) Akanmori, B.D.; Afari, E.A.; Sakatoku, H.; Nkrumah, F.K.
