ABSTRACT
BACKGROUND: Case detection is an important part of TB control programmes. In 2007, the TB programme in Ghana join the WHO´s public-private partnership with community medicine outlet operators to increase referral of persons with presumptive TB for laboratory investigation. Information on factors likely to influence referral is scarce in Ghana. We assessed these factors among pharmacists and over-the-counter (OTC) medicine sellers.METHODS: In 2019-2020, we conducted computer-assisted telephone interviews among community pharmacists and OTC medicine sellers in the Eastern Region of Ghana. We used a structured questionnaire and collected data on respondents´ sociodemographics and professional characteristics. We used logistic regression to investigate characteristics associated with self-reported referral of presumptive TB cases.RESULTS: Of all respondents who completed the interviews, 68.7% (321/467) reported having ever referred a presumptive TB case and 72.1% (336/466) had received specific training. Associated factors of presumptive TB referral were having received specific training (OR 2.7, 95% CI 1.5-4.9); performing both dispensing and managerial functions (OR 2.8, 95% CI 1.4-5.5); operating from OTC shop (OR 6.2, 95% CI 1.6-23.4) and the availability of a TB laboratory within walking distance (OR 3.3, 95% CI 1.2-9.5).CONCLUSION: Interviewees largely support TB referral. However, a significant proportion does not follow the strategy closely. We recommend more specific TB training courses.

BACKGROUND: The aims of this study were to characterize the patients seeking acute care for injury and non-injury complaints in an urban Emergency Department in Ghana in order to 1) inform the curriculum of the newly developed Emergency Medicine resident training program 2) improve treatment processes, and 3) direct future community-wide injury prevention policies. STUDY DESIGN: A prospective cross-sectional survey of patients 18 years or older seeking care in an urban Accident and Emergency Center (AEC) was conducted between 7/13/2009 and 7/30/2009. Questionnaires were administered by trained research staff and each survey took 10-15 minutes to complete. Patients were asked questions regarding demographics, overall health and chief complaint. RESULTS: 254 patients were included in the sample. Participants' chief complaints were classified as either medical or injury-related. Approximately one third (38%) of patients presented with injuries and 62% presented for medical complaints. The most common injury at presentation was due to a road traffic injury, followed by falls and assault/fight. The most common medical presentation was abdominal pain followed by difficulty breathing and fainting/ blackout. Only 13% arrived to AEC by ambulance and 51% were unable to ambulate at the time of presentation. CONCLUSION: Approximately one-third of non-fatal adult visits were for acute injury. Future research should focus on developing surveillance systems for both medical and trauma patients. Physicians that are specifically trained to manage both the acutely injured patient and the medical patient will serve this population well given the variety of patients that seek care at the AEC.

BACKGROUND AND METHODS: Twenty-five thrombocytopenic patients underwent quantitative in vivo platelet kinetic studies using a scintillation camera and a computer-assisted imaging system. They fulfilled the criteria for chronic immune thrombocytopenia, and the object of the study was to evaluate platelet sequestration and destruction in the spleen. In this sense, the differences in the distribution of the radiolabelled platelets in the spleen and the liver, as well as the differences in the platelet mean life span (MLS) as computed by different methods were assessed. Serial images of the spleen pool, liver and heart were taken after reinjection of In-111-oxine labelled autologous platelets. RESULTS AND CONCLUSIONS: The spleen/liver ratio proved to be a more reliable index in indicating the splenectomy outcome that the Z index (see text). Platelet survival curves were analyzed using four mathematical models, and it was found that MLS estimation is model dependent. Thus, it seem advisable to apply at least two different methods when analyzing experimental data.

A transportable apparatus for isotope renography, which allowed deconvolution analysis, was used to study the prevalence and prognosis of abnormalities associated with urinary schistosomiasis. Before carrying out studies in a heavily infected community, observations were made in a non-endemic area to allow derivation of criteria for abnormality. Comparison of the findings in the two areas showed that changes suggesting urinary tract obstruction were more common in the endemic area in subjects between nine and 45 years but not in older subjects. Measurements of effective renal plasma flow showed renal function was impaired in the endemic area in subjects older than 17 years but not in younger subjects. In the endemic area the results of renography were unrelated to the urinary egg count of the subjects examined, but there was an improvement in the abnormal renograms in a group of subjects aged between nine and 20 years who were re-examined a year after treatment with metrifonate. Follow-up data about 316 subjects was obtained two years after renography. Nine subjects had died, including four of the five subjects with abnormalities suggesting both obstruction and over-all loss of renal function. These findings, which are comparable to the results of similar studies using radiological techniques, suggest urinary schistosomiasis may be a significant cause of mortality in adults in intensely infected communities.
