SUMMARYA seroepidemiological study of Brucella infections in multiple livestock species in the Borana pastoral system of Ethiopia was performed between December 2007 and October 2008. A cross-sectional multi-stage sampling technique was employed to select 575 cattle, 1073 camels and 1248 goats from the target populations. Sera were collected from the animals, and serially tested using Rose Bengal test and complement fixation test. Overall prevalence and prevalence with respect to explanatory variables were established, and potential risk factors for seropositivity were analysed using a multivariable logistic regression. The results showed that 8·0% (95% CI 6·0–10·6), 1·8% (95% CI 1·1–2·8) and 1·6% (95% CI 1·0–2·5) of the tested cattle, camels and goats, respectively, had antibodies to Brucella antigen. Positive reactors were found in 93·8% of the villages with more frequent detection of positive cattle (93·3%) than camels (56·3%) and goats (37·5%). Risk factors identified for cattle were: keeping more livestock species at household level (OR 4·1, 95% CI 1·9–8·9), increasing age of the animal (OR 2·8, 95% CI 1·3–6·0) and wet season (OR 3·3, 95% CI 1·6–6·9). Increase in household-level species composition (OR 4·1, 95% CI 1·2–14·2) and wet season (OR 3·7, 95% CI 1·5–9·1) were found to be risk factors for seropositivity in camels and goats, respectively. Existence of more than one seroreactor animal species in most villages and association of increased livestock species composition with seropositivity may add more credence to the possibility of cross-species transmission of Brucella infections. Although no attempt to isolate Brucella spp. was made, our results suggest that cattle are more likely maintenance hosts of Brucella abortus which has spread to goats and camels. This should be substantiated by further isolation and identification of Brucella organisms to trace the source of infection and transmission dynamics in various hosts kept under mixed conditions. In conclusion, the present study suggests the need for investigating a feasible control intervention and raising public awareness on prevention methods of human exposure to brucellosis.

Background: Infections with Hepatitis B Virus (HBV) and Hepatitis C virus (HCV) are worldwide public health problem. Thisis related to the continued occurrence of new infections and the presence of a large reservoir of chronically infected persons. Objective:To determine the frequency of risk factors (causes of transmission) for HBV and HCV infections in hospitalized patients of CMH, Lahoreand Sheikh Zayed hospital, Lahore. Design: Descriptive (cross sectional). Setting: The study was carried out in CMH, Lahore and SheikhZayed hospital, Lahore from January, 2012 to July, 2012. Methods: The patients were selected by consecutive (non-probability)sampling technique. The data was collected through questionnaire. Informed written consent was obtained SPSS version 16.0 was usedto calculate the descriptive statistics. Results: Out of total of 100 subjects, 50 were cases and 50 were controls. Out of 50 cases, 26%were HBV positive and 74% were HCV positive with female preponderance. The history of injections was very high in both the groups,making a total of 64% (14% HBV; 16% HCV) the important contributors for different types of hepatitis were blood transfusion (HBV =10%; HCV = 28%; controls = 14%). Surgical procedures (4% HBV, 28% HCV; 8% controls). History of piercing in the last six months(HBV = 6%; HCV = 22% and control = 8%). History of dental procedures in the last six months was higher in HCV patients (18% HCV and4% HBV). History of HBV or HCV positive patients or relatives at home. (HBV 18%; HCV 36%; control 30%). Conclusions: In Pakistan thereis an urgent need to raise the public awareness about importance of properly screened blood transfusion, use of disposable needles andusing new blades for shaving and haircuts especially at barber shops. In our study, the important contributors for different types ofhepatitis were blood transfusion, surgical procedures and history piercing in the last 6months.

Background. Iodine deficiency has serious effects on body growth and mental development. This study assessed availability of adequately iodized salt at household level and associated factors in Gondar town, northwest Ethiopia. Methods. Community based cross-sectional study was carried out among households in Gondar town during August 15–25, 2012. Multistage sampling technique was used. Data were collected using a pretested and structured questionnaire by a face-to-face interview technique. Bivariate and multivariate analyses were performed to check associations and control confounding. Results. A total of 810 participants were participated. The availability of adequately iodized salt (≥15 parts per million) in the study area was 28.9%. Multivariate analysis showed that using packed salt (AOR (95% CI) = 9.75 (5.74, 16.56)), not exposing salt to sunlight (AOR (95% CI) = 7.26 (3.73, 14.11)), shorter storage of salt at household (AOR (95% CI) = 3.604 (1.402, 9.267)) and good knowledge of participants about iodized salt (AOR (95% CI) = 1.94 (1.23, 3.05)) were associated with availability of adequately iodized salt at household level. Conclusions. Availability of adequately iodized salt at household level was very low. Hence, households should be sensitized about importance of iodized salt and its proper handling at the household level.

Aim The study was conducted to determine the prevalence of hydatidosis, to identify the association between expected risk factors and occurrence of the disease, to investigate economic importance and to evaluate fertility and viability of the hydatid cyst in cattle slaughtered at the abattoir. Materials and Methods A cross-sectional study, which involves both ante-mortem and post-mortem examination, was conducted at Nekemte municipal abattoir from November 2015 to March 2016. Results A total of 355 local cattle breed was randomly sampled and examined for the presence of hydatid cysts in the organs of the animals using the standard meat inspection procedures, 66 (18.6%) animals were found harboring hydatid cysts. Statistical analysis showed that there was a significant difference (p<0.05) between the prevalence of bovine hydatidosis in all risk factors with exception of sex of the animals. Among 207 hydatid cysts recorded, 93 (44.92%) were from lungs, 65 (31.40%) from livers, 4 (1.93%) from heart, 3 (1.44%) from kidney, 1 (0.48%) from spleen and 41 (19.8%) were in two organs from lung and liver. Fifty-seven (57) of these 207 cysts were randomly selected and subjected to fertility and viability test which revealed 19 (33.33%) as fertile, 25 (43.86 %) sterile and 13 (22.81%) calcified. Viability test proved 7 (12.28%) of 19 fertile cysts as viable and 12 (21.05%) of 19 fertile cysts as non-viable. Viability of cysts in different organs revealed that 5 (16.1%) and 2 (10%) of cysts from lungs and liver, respectively. The estimated financial loss during the study period both due to condemnation of organs and an in direct carcass weight loss from hydatidosis was 2,190,143.52 ETB. Conclusion The results of this study revealed that bovine hydatidosis was an economically important disease of cattle which need serious attention for prevention and control actions in and around Nekemte. Hence, establishment of well-equipped standardized abattoirs, prohibition of backyard slaughter, creation of public awareness, deworming and control of stray dogs are of paramount importance.

Smear Positive Pulmonary Tuberculosis

Objective: To evaluate risk factors having significant effect on mortality of smear positive Pulmonary Tuberculosis (PTB) inpatients. Methods: A descriptive cross-sectional study was conducted at Ojha Institute of Chest Diseases, Dow University Hospital Ojha Campus, Karachi. One hundred and seventy (170) inpatients of smear positive PTB confirmed by Acid Fast Bacilli (AFB) smear, aged between 13-80 years were enrolled by using consecutive sampling technique while patients with drug resistant Tuberculosis (TB) and extra pulmonary TB were excluded from the study. Selected patients were interviewed for collecting demographic data and risk factor data by using a standard questionnaire. Results: Out of 170 PTB inpatients, mortality was observed in 23 (13.5%) patients among which male patients were 12 (52.2%), and female were 11 (47.8%). Mortality was significantly associated with increasing age (p=0.003), socioeconomic status (p=0.019), anemia (p=0.03), Chronic Liver Disease (CLD) (p=0.005), Diabetes Mellitus (DM) (p=0.001), Human Immunodeficiency Virus (HIV) (p=0.007), Hypertension (HTN) (p=0.006), recurrent TB (p=0.001), and smoking (p=0.001). Conclusion: Increasing age, poverty, smoking history, and presence of comorbidities like DM, CLD, HIV, hypertension, and anemia are associated with higher mortality in smear positive PTB cases. doi: https://doi.org/10.12669/pjms.35.5.919 How to cite this:Hameed S, Zuberi FF, Hussain S, Ali SK.

BACKGROUND: Rheumatic Heart Disease (RHD) is a disease of developing countries where it inflects significant burden dis-proportionality. We investigated the role of socio-economic and environmental risk factors for RHD. METHODS:· This was descriptive cross-sectional conducted at Pakistan Institute of Medical Sciences Islamabad by including the patients coming to cardiology out door patient department through convenient sampling technique. Study was approved from ethical committee of Pakistan institute of Medical Sciences Islamabad and written consent was taken prior to start the interview. RESULTS: In this study, the average age of patient with rheumatic heart disease was 29.4 years, male predominance of patients was observed. 67% of subjects had income below Rs. 20,000. Average BMI of subjects was 22.4±4.04. It was observed that 75.25 % of people lived in houses with an area of less than 5 marla. Average area of house was found to be 5.12±2.8 marla. Overcrowding was noticed in 60.8 % of the subjects. CONCLUSION: There is a high prevalence of RHD and Acute Rheumatic Fever (ARF) in Pakistan. The major findings of this study were that Overcrowding, poor hygienic conditions, low socio-economic status, are major risk factors for RHD. In order to address this alarming situation, platforms like Pakistan Pediatric Cardiac Society and Pakistan Pediatric Association need to be mobilized for health promotion regarding awareness of the disease.

Food Of Animal Origin

Background. Salmonella has been recognized as a major cause of food-borne illness associated with the consumption of food of animal origin. The present cross-sectional study was conducted from December 2017 to May 2018 in Ambo and Holeta towns to assess the prevalence, risk factors, and antimicrobial susceptibility patterns of nontyphoidal Salmonella isolates from raw beef samples from abattoirs, butchers, and restaurants in Ambo and Holeta towns, Oromia region, Ethiopia. Methods. A total of 354 beef samples were collected from abattoirs, butchers, and restaurants. Salmonella isolation and identification were carried out using standard bacteriological methods recommended by the International Organization for Standardization. Antimicrobial susceptibility testing was performed using the disk diffusion method. Besides, a structured questionnaire was used to collect sociodemographic data and potential risk factors for contamination of meat. Chi-square tests and logistic regression were used for data analyses. Results. Of the total 354 meat samples examined, 20 (5.7%, 95% confidence interval (CI): 3.5–8.6) were positive for Salmonella. Two serotypes belonging to S. typhimurium (11 isolates) and I:4,5,12: i:- (9 isolates) were identified. The Salmonella detection rate in abattoirs, butchers, and restaurants was 4.2% (5/118), 8.5% (10/118), and 4.2% (5/118), respectively. The antimicrobial susceptibility test showed that 40%, 30%, and 20% of the Salmonella isolates were resistant to azithromycin, amoxicillin, and ceftriaxone, respectively. The odds of Salmonella isolation when meat handlers are illiterate were 7.8 times higher than those when they are educated to the level of secondary and above ( P = 0.032 ). Similarly, the likelihood of Salmonella isolation was 6.3 and 7.6 times higher among workers of butcher and restaurants, respectively, who had no training ( P = 0.003 ) and no knowledge ( P = 0.010 ) on food safety and hygiene. Conclusions. The study showed widespread multidrug-resistant Salmonella isolates in the study areas. Therefore, raw meat consumption and indiscriminate use of antimicrobial drugs should be discouraged. Provision of food safety education for meat handlers and further surveillance of antimicrobial-resistant isolates are suggested.

Background. Schistosomiasis is one of the Neglected Tropical Diseases in Ethiopia, and its burden may show variations from time to time across different regions. Thus, this study was aimed at determining the prevalence, intensity, and associated risk factors of Schistosoma mansoni (S. mansoni) among schoolchildren in Northwest Ethiopia. Methods. A school-based cross-sectional study was conducted. A multistage sampling technique was used to select the study participants. Stool specimens were collected and examined using two-slide Kato-Katz method. Data were analyzed using SPSS version 20 software. Multivariate logistic regression analysis was used to identify risk factors. p values less than 0.05 were taken as statistically significant. Result. A total of 786 schoolchildren were participated in this study. The prevalence of S. mansoni was 33.5%. The mean egg count of the parasite among the infected study participants was 523.665 eggs per gram (epg) of stool. Thirty-seven, 42, and 21 percent of the study participant’s infection were due to light, moderate, and heavy infection intensities, respectively. Age of 8-11 years old ( AOR = 1,687 , 95 % CI = 1.163 , 2.892 ), 5th-8th grade level ( AOR = 2.280 , 95 % CI = 1.348 , 3.856 ), residing in Chuahit District ( AOR = 95.559 , 95 % CI = 12.945 , 705.419 ), and using untreated water for domestic supply ( AOR = 1.724 , 95 % CI = 1.457 , 2.148 ) were found to be risk factors for S. mansoni infection. Conclusion. High prevalence of S. mansoni and relatively higher proportion of moderate intensity of infection in this study imply that schistosomiasis is still one of the major public health problems in Northwest Ethiopia. It is also highlighted that study sites, provision of water supply, age, and grade level of the schoolchildren were identified as a risk factors for the disease.

In Ethiopia, Iodine Deficiency Disorder has been recognized as a serious public health problem for the past six decades. In 2011, an estimated <br /> 12 million school-age children were living with inadequate iodine, and <br /> 66 million people were at risk of iodine deficiency. One out of every <br /> 1000 people is a cretin mentally handicapped, due to a congenital thyroid deficiency, and about 50000 prenatal deaths are occurring annually due to iodine deficiency disorders. Only 5.7% of the households were using iodized salt in Dire Dawa city Administration, which is below the legal requirement.This study assessed availability of adequately iodized salt at household level and associated factors in Dire Dawa town, East Ethiopia. Community based cross-sectional study was carried out among households in Dire Dawa town during March 16-26, 2015. Multistage sampling technique was used. Data were collected using a pretested and structured questionnaire by a face-to-face interview technique. Bivariate and multivariate analyses were performed to check associations and control confounding. A total of 694 participants were participated. The availability of adequately iodized salt (≥15 parts per million) in the study area was 7.5% (95% CI; 5.6-9.5). Multivariate result showed that health information about iodized salt (AOR=8.96, 95% CI; 4.68-17.16) (p=0.03), good knowledge about iodized salt (AOR=9.23, 95% CI; 3.34-25.5) (p=0.01) and using packed salt (AOR=3.99, 95% CI; 1.48-10.73) (p=0.006) were associated with availability of adequately iodized salt at household level. Availability of adequately iodized salt at household level was very low.  Hence, households should be sensitized about importance of iodized salt and its proper handling at the household level.
