Prevalence and Factors Associated with Group A Rotavirus Infection Among Children with Acute Diarrhea in Mwanza, Tanzania.
Rotavirus infections frequently cause acute gastroenteritis in humans and are the most important cause of severe dehydrating diarrhea in young children in both developed and developing countries. This was a prospective cross-sectional, hospital-based study on 300 children ≤ 5 years with acute watery diarrhea who attended Bugando Medical Centre (BMC) and Nyamagana District hospital between May and November 2009. Stool specimens were tested for rotavirus infection using latex agglutination test. Data were cleaned and analyzed using SPSS 11.0. Of 300 children with acute watery diarrhea, 136 (45.3%) were female and the mean age was 12.63 months (SD = 10.4). Sixty-two (20.7%) children were found to have rotavirus infection. Of children with severe malnutrition three (37.5%) were infected with rotavirus. Fifty-two (84%) of children with rotavirus infection were below two years of age. Severe dehydration was present in 48 (16%) children of whom 12 (25%) were infected with rotavirus compared to 18 (16.6%) of 109 children with no dehydration. Living next door to a child with diarrhea was highly associated with rotavirus infection (43% versus 19%; p = 0.036). The mean hospital stay among children with rotavirus infection was 3.66 days versus 2.5 days for those without rotavirus (p = 0.005). Rotavirus infection is prevalent in Mwanza region and contributes to prolonged hospital stay. Proper education on hygiene to control diarrheal diseases among children should be emphasized. Extensive studies to determine the serotypes of rotavirus are warranted in the region before rotavirus vaccine is introduced
The KELT-South Telescope
The Kilodegree Extremely Little Telescope (KELT) project is a survey for new
transiting planets around bright stars. KELT-South is a small-aperture,
wide-field automated telescope located at Sutherland, South Africa. The
telescope surveys a set of 26 degree by 26 degree fields around the southern
sky, and targets stars in the range of 8 < V < 10 mag, searching for transits
by Hot Jupiters. This paper describes the KELT-South system hardware and
software and discusses the quality of the observations. We show that KELT-South
is able to achieve the necessary photometric precision to detect transits of
Hot Jupiters around solar-type main-sequence stars.Comment: 26 pages, 13 figure
The orbit space of groupoids whose -algebras are GCR
Let be second countable locally compact Hausdorff groupoid with a
continuous Haar system. We remove the assumption of amenability in a theorem by
Clark about GCR groupoid -algebras. We show that if the groupoid
-algebra of is GCR then the orbits of are locally closed.Comment: 1
Potential for medical error : incorrectly completed request forms for thyroid function tests limit pathologists' advice to clinicians
ArticleThe original publication is available at http://www.samj.org.zaBackground. Various publications have highlighted the significance of laboratory errors in the pre- and post-analytical phases and their impact on results. Thyroid-stimulating hormone (TSH) is a first-line thyroid function test and, if abnormal, reflex thyroxine (T4) or tri-iodothyronine (T3) testing is requested, depending on clinical and medication data provided. Interpretative comments are added to all TFT results. Objectives. In view of the paucity of articles describing such errors, we audited laboratory request forms requesting thyroid function tests (TFT), received from primary care clinics and regional hospitals at our laboratory. Design. We assessed 482 laboratory request forms for TFT from primary health care clinics for specific parameters. Results. A total of 482 forms were analysed. Medication/s used by the patient (74.5%) and doctor's contact number (65.1%) were the most commonly incomplete parameters. Of the 123 patients with medication details, 62 (50.4%) were on thyroxine. Conclusions. There are few studies examining the frequency and impact of incomplete laboratory forms on laboratory errors, and even fewer studies examining interpretative comments accompanying clinical biochemistry results. We studied how pre-analytical errors in completing request forms may lead to incorrect interpretative comments and inappropriate reflex testing, and so influence the quality of the post-analytical phase

An audit of 24-hour creatinine clearance measurements at Tygerberg Hospital and comparison with prediction equations
ArticleThe original publication is available at http://www.samj.org.zaBibliographyBACKGROUND: Internationally, clinical guidelines recommend the use of creatinine-based equations to estimate glomerular filtration rate (GFR) for assessment and follow-up of kidney disease. The routine use of 24-hour creatinine clearances (CrCl) is no longer advocated. Objectives. To examine the indications for requesting CrCl at Tygerberg Hospital, identify problems associated with the procedure, and evaluate the utility of the Cockcroft-Gault (CG) and Modification of Diet in Renal Disease (MDRD) equations with different levels of renal dysfunction in the ethnic groups of the Western Cape. Methods. A clinical audit of CrCl was performed. The estimated GFR as predicted by the modified CG and MDRD formulae was compared with CrCl in 252 patients, representing three local ethnic groups. MDRD formulae with and without the correction factor for black ethnic group (MDRD-B) were evaluated. Results. Problems with urine collection or data supplied were identified in one-third of CrCl requests, leading to unreliable results. The CG correlated best with CrCl in the group as a whole. The average absolute and percentage differences from CrCl in the different ethnic groups were as follows: coloured (mixed ethnicity) (N = 186) - CG 13.4 ml/min/1.73 m2 (18%), MDRD 16.8 ml/min/1.73 m2 (23%) and MDRD-B 27.9 ml/mim/1.73 m2 (37%); black (N = 21) - CG 14.8 ml/min/1.73 m2 (19%), MDRD 12.9 ml/min/1.73 m2 (17%) and MDRD-B 25.1 ml/min/1.73 m2 (33%); white (N = 45) CG 13.5 ml/min/1.73 m2 (19%), MDRD 15.3 ml/min/1.73 m2 (21%) and MDRD-B 24.8 ml/min/1.73 m2 (35%). Throughout the renal function levels (chronic kidney disease stages 1 - 5) CG correlated better with CrCl than MDRD. Conclusions. Possible reasons for poor correlations include a high prevalence of obesity, underweight and normal GFR in the study population. There is a need for further research, using a gold standard, into the accuracy of these prediction equations in our unique patient populations before firm recommendations can be made regarding their use. Until then CrCl will continue to be widely used. Greater efforts at patient and health care worker education are required to ensure proper collections.Publishers' Versio
