This cross sectional study was carried out in SSMC for a period of one year from July 2007 to June 2008 to evaluate rK39 based ELISA and KAtex tests for diagnosis of Kala-azar. Total 150 patients were selected clinically. For this study rK39 ICT was regarded as confirmatory test according to national guideline. Among 150, total 100 cases were confirmed to be positive for Kala-azar by rK39 ICT test. Age and sex matched 25 healthy persons each from endemic and non-endemic area were taken as control. Among the 100 sero confirmed cases KAtex was positive in 87 (sensitivity of 87%) while ELISA was positive in 98 cases (sensitivity 98%). Among the 50 controls none were positive by KAtex test while 1 (one) ELISA test was positive resulting in specificity of these tests 100% and 98% respectively. The result of the study clearly showed superiority of rK39 antigen based ELISA in respect of sensitivity and KAtex in respect of specificity.KYAMC Journal Vol. 6, No.-1, Jul 2015, Page 574-578

Background: Early diagnosis of Kala-azar is of prime importance to reduce the transmission of the disease. Objective: The purpose of the present study was to evaluate KAtex test for the diagnosis of Kala-azar. Methodology: This cross sectional study was carried out in Department of Microbiology at Sir Salimullah Medical College, Dhaka for a period of one year from July 2007 to June 2008. Patients were selected clinically form all age and sex group hailing from endemic region of Mymensingh in a semi purposive manner excluding those who have already started taking medicine or refused to participate in the study.  Blood and urine samples were collected from the patients admitted in Sir Salimullah Medical College, Dhaka, Mymensingh Medical College and Bhaluka Health Complex, Mymensingh.  Result: Among 150 of the clinically selected patients, total 100 cases were confirmed to be positive for Kala-azar by rK39 ICT test. Age and sex matched 25 healthy persons each from endemic and non-endemic area was taken as control. Among the 100 sero-confirmed cases KAtex was positive in 87 (sensitivity of 87%). Among the 50 controls none were positive by KAtex test resulting in specificity of these tests 100% and 98% respectively. Conclusion: KAtex test has high sensitivity and specificity for the diagnosis of Kala-azar patients at endemic region of Bangladesh.Bangladesh J Infect Dis 2014;1(1):8-11

The sera from 120 boars from 3 farrow-to-finish swine herds in Serbia were examined for Salmonella spp. antibodies in a cross-sectional study using an ELISA test. A total of 120 blood serum samples from boars imported from Denmark were examined. All boars were seronegative to Salmonella during the import, while after one year Salmonella spp. seroprevalence ranging from 0% to 45% was found in 3 herds using two tests in the time span of one year. Only on one farm during the import in 2011, after a year boars were still seronegative. A year later on the same farm, in boars imported in 2012 the seroprevalence was 30%. Seroprevalence of Salmonella spp. in boars tested on all farms was 24,17%.

Spontaneous Subarachnoid Hemorrhage

Background: In evaluation of non-traumatic subarachnoid hemorrhage CT angiography (CTA) has 97-98% sensitivity and near 100% specificity. Objective: This study was conducted to evaluate the CTA findings of CT positive non traumatic subarachnoid hemorrhage. Methodology: This is an observational cross sectional study performed in Neurology department of National Institute of Neurosciences and Hospital, Dhaka over one year period (January 2019 to December 2019). Total 87 CT positive subarachnoid hemorrhage cases were purposively included in this study. All CT positive patients underwent CTA of Cerebral vessels for further evaluation. The angiography were evaluated by competent neuro-radiologists blinded about the study. Result: Among 87 patients, 40.2% were male and 59.8% were female. The average age was 53.33±11.1 years. Among the studied patient the source of bleeding was found 78.16% aneurysmal and 21.84% non-aneurysmal. 85.30% patients had single aneurysm and 14.70% had multiple aneurysm. The highest number of patient had Acom aneurysm (41.17%) followed by MCA (22.05%), ICA (13.23%), ACA (7.35%) and vertebral artery (1.14%) in order of frequency. Among the multiple aneurysm group most of the patients had combination of Acom, MCA and ICA aneurysm. Conclusion: From this study, we can conclude that CTA can be used as the primary diagnostic tool in evaluation of spontaneous SAH.

Background:Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by multisystem inflammatory lesions affecting many organ systems in the body. Familial Mediterranean fever (FMF) is an autosomal recessive disease of chronic autoimmune inflammation characterized by frequently relapsing self-limiting fever and inflammation that may be localized in peritoneum, pleura, joint or skin.1Previous studies have described the similarity of clinical symptoms of FMF among SLE patients. However, the literature on this topic is inconsistent and based mostly on case reports.2-4Objectives:To examine the proportions of coexistence of FMF among SLE patients compared to the general population. We hypothesized that the proportion of FMF among SLE patients is higher than the general population.Methods:This cross-sectional study used the Clalit Health Services database, the largest Health Maintenance Organization in Israel, serving 4,400,000 members. SLE patients were compared to age- and sex-matched controls. Chi- was used for univariate analysis.Results:The study included4886 SLEpatients and 24430 age- and sex-matched controls. The SLE group had a significantly higher proportion of FMF patients compared to non-SLE controls (0.68% and 0.21% respectively; p < 0.001).Table 1.

Populations At Risk

AbstractThe prevalence of anti-hepatitis E virus (HEV) antibodies has a high heterogeneity worldwide. South American data are still scarce. The aim of this study was to evaluate the prevalence of HEV in populations at risk in comparison to blood donors (BD). A cross-sectional study was carried out in adults of different risk populations including crack users (CK), residents in a low income area (LIA), cirrhotic (CIR) and liver transplant patients (LT) compared with BD. The WANTAI HEV ELISA test was used and real-time PCR (in-house for screening and ALTONA as confirmatory test) for HEV RNA screening. A total of 400 participants were included. Anti-HEV IgG was positive in 19.5% of the total sample, reaching the highest rate in the CIR group, 22.5%, followed by CK, LT, and LIA (20%, 18.7%, and 17.5%, respectively). The prevalence found in BD individuals was of 18.7% (p = NS). Anti-HEV IgM was positive in only 1.5% of the sample (6/400). No blood or stools samples were positive for HEV RNA. The seroprevalence reported is among the highest rates ever found in Brazil. Considering the intense diagnostic investigation, data show that HEV circulation is more common that might be expected in our country.

Brucellosis is an important bacterial zoonotic disease causing significant economic loss in dairy industries worldwide including Bangladesh. But limited studies are devoted to determine the prevalence of brucellosis in goat in all districts of Bangladesh. Therefore, a cross-sectional study was undertaken to determine the seroprevalence of brucellosis in Black Bengal goats in Nilphamari Sadar and Kishoreganj upazillas of Nilphamari district of Bangladesh using Rose Bengal Test (RBT) as screening test and I-ELISA as confirmatory test. A total of 154 sera samples from Black Bengal goats were collected from Nilphamari district. Epidemiological data on the selected Black Bengal goats were collected using a structured questionnaire. The overall seroprevalence of brucellosis was found to be 2.59% in Black Bengal goats. A significantly (p<0.01) higher prevalence of brucellosis was found in Black Bengal goats with the history of previous abortion (33.33%). An insignificant (p>0.05) but higher prevalence of brucellosis was found in adult Black Bengal goats (>24 months) than young. The prevalence was relatively higher in cross-bred than pure Black Bengal goats, in female than male and in pregnant than non-pregnant Black Bengal goats. The result of the study will provide baseline data for control of brucellosis in goat in Bangladesh.DOI: http://dx.doi.org/10.3329/bjvm.v10i1-2.15646
