Choriocarcinoma metastatic to both kidneys presenting with spontaneous renal hemorrhage: Case report.

INTRODUCTION: Choricocarcinoma is a highly malignant tumor. It metastasize commonly to the lungs. Metastasis to the kidney is uncommon, and bilateral metastasis is described rarely. Initial presentation with spontaneous bleeding of the renal metastatic tumor is scarce in the literatures. Here we present a case report of a choriocarcinoma patient with bilateral renal metastasis, presenting with spontaneous renal hemorrhage. CASE PRESENTATION: A 22 years old female presented to our emergency department with sudden onset of left flank pain. She has history of spontaneous abortion 02 years back with biopsy from the manual vacuum aspiration (MVA) showing molar pregnancy. Up on evaluation, patient was anemic. CT scan showed left renal bleeding tumor. Exploratory laparotomy and radical nephrectomy was done with the impression of bleeding renal cell carcinoma. The biopsy revealed choriocarcinoma. On her follow up, CT scan showed right renal and brain metastasis. She was given multi agent chemotherapy and her serum beta-hCG became undetectable after 01 year. DISCUSSION: Choriocarcinoma can be gestational or nongestational. The commonest route of metastasis is hematogenous. Presenting symptoms of renal metastasis can be hematuria, pain or more commonly incidental finding during work up. Choriocarcinoma is highly chemo sensitive. CONCLUSION: Bilateral renal metastatic choriocarcinoma is uncommon. Spontaneous renal hemorrhage as an initial presentation is even rare, and it can mimic a bleeding renal cell carcinoma. High index of suspicion is needed in a young women with recent history of spontaneous abortion.

Post catheterization Fournier's gangrene involving the entire anterior urethra: case report.

INTRODUCTION AND IMPORTANCE: Fournier's gangrene is necrotizing fasciitis involving the penis, scrotum, or perineal region. This is to report necrosis of the entire anterior urethra by necrotizing infection even though the involvement of the urethra by Fournier's is a very rare presentation. A high index of suspicion is important for early intervention. The main Mode of treatment for Fournier's gangrene is debridement. CASE PRESENTATION: This is a case report for a 58-year-old male patient who presented with penile and scrotal swelling after he was catheterized with NG tube for acute urinary retention. The physical finding shows swollen scrotum with ulcerated necrotic glans penis anteriorly. Laboratory result shows leukocytosis and urine analysis is positive for urinary tract infection and ultrasound shows bladder diverticula with normal prostate volume. He underwent debridement up to the level of membranous urethra and suprapubic catheterization was done. He was treated with antibiotics and wound care and finally, the wound closed. Post-operative cystourethrography was done 9 months later and we offered staged urethroplasty but he decided for permanent SPC. DISCUSSION: Fournier's gangrene is a fatal rapidly spreading infection that occurs in the perineal area. Involvement of urethra by necrotizing infection following catheterization is very rare presentation and diagnosis is mostly clinical. Once it is diagnosed the management is surgical debridement. CONCLUSION: Fournier's gangrene with urethral involvement is a very rare presentation and a high index of suspicion is important for early diagnosis and management. Following the standard procedural steps of catheterization is important to avoid this complication.

Isolated renal hydatid cyst.

INTRODUCTION AND IMPORTANCE: Hydatid disease, is a parasitic disease caused by the larval stage of the cestode Echinococcus granulosus. The Liver and lungs are the commonly affected organs but rarely kidney can be affected. Patient with primary renal hydatid may present with nonspecific symptoms or may be diagnosed incidentally. Imaging and serology are useful for diagnosis. The best therapy is surgery. CASE PRESENTATION: This case is reported to discuss a 35-year-old female presented with complaints of left side flank pain and swelling. The abdominal US and CECT show renal cyst, which was nonspecific. She underwent an open surgical exploration and cystectomy plus partial pericystectomy done. Post-operative serology test show Echinococcus IgG positive. Postoperatively, the patient had an uneventful recovery and discharged with Albendazole therapy for 8 weeks. CLINICAL DISCUSSION: Renal hydatid cyst is rare, accounting for less than 2 to 3 % of all hydatid disease. Renal hydatid cysts can remain asymptomatic for many years and then can be discovered incidentally. The diagnosis and staging of renal hydatid cysts rely heavily on imaging and serology. Hydatid disease is primarily treated surgically. CONCLUSION: A high index of suspicion should be maintained, especially in endemic areas, to ensure timely and accurate diagnosis of renal hydatid cyst. Surgical excision remains the treatment of choice, with appropriate preoperative and postoperative anthelminthic therapy. Long-term follow-up is crucial to monitor for recurrence and associated complications.

A case report on the atypical presentation of Renal tuberculosis as emphysematous pyelonephritis.

INTRODUCTION AND IMPORTANCE: Emphysematous pyelonephritis (EPN) is a severe acute necrotizing infection, that causes gas to build up in the collecting system, renal parenchyma, and perirenal tissues (Mahmood et al., 2020). Uncontrolled diabetes mellitus and urinary tract obstruction are the two main risk factors. We report the second case report of tuberculosis as a causative pathogen of EPN. CASE PRESENTATION: In this case report, a 60-year-old lady with poorly controlled type 2 diabetes was admitted to the emergency room due to left flank pain, a low-grade temperature, nausea, and vomiting. Emphysematous Pyelonephritis was diagnosed based on gas seen in the renal parenchyma on a CECT scan (EPN). She underwent conservative management, including the insertion of a nephrostomy tube and antibiotics. There is no growth detected in the nephrostomy drain's culture. She underwent a simple nephrectomy after deciding that she had not improved clinically after receiving conservative treatment. A biopsy of the specimen revealed a tuberculosis abscess. She received the proper care and made clinical progress over the course of a six-month anti-TB medication regimen. CLINICAL DISCUSSION: The majority of EPN patients are female (2:1) and diabetic (90 %) with a mean age of presentation of 55 years (El Rahman et al., 2011). The preferred method of diagnosis for EPN is CT (El Rahman et al., 2011). E. coli, Klebsiella, and Pseudomonas were the most prevalent species in many of the reported cases (Khaira et al., 2009). In contrast to prior investigations, we discovered a case of EPN caused by tuberculosis invasion. CONCLUSION: An essential lesson to learn from such cases is the importance of considering genitourinary tuberculosis when emphysematous pyelonephritis does not improve with conservative treatment, especially in areas with a high tuberculosis endemicity.

Epidemiological, Entomological, and Climatological Investigation of the 2019 Dengue Fever Outbreak in Gewane District, Afar Region, North-East Ethiopia.

Dengue Fever (DF) is an important arthropod-borne viral infection that has repeatedly occurred as outbreaks in eastern and northeastern Ethiopia since 2013. A cross-sectional epidemiological outbreak investigation was carried out from September to November 2019 on febrile patients (confirmed malaria negative) who presented with suspected and confirmed DF at both public and private health facilities in Gewane District, Afar Region, northeastern Ethiopia. Entomological investigation of containers found in randomly selected houses belonging to DF-positive patients was undertaken to survey for the presence of Aedes larvae/pupae. A total of 1185 DF cases were recorded from six health facilities during the 3-month study period. The mean age of DF cases was 27.2 years, and 42.7% of cases were female. The most affected age group was 15−49 years old (78.98%). The total case proportions differed significantly across age groups when compared to the population distribution; there were approximately 15% and 5% higher case proportions among those aged 15−49 years and 49+ years, respectively. A total of 162 artificial containers were inspected from 62 houses, with 49.4% found positive for Aedes aegypti larva/pupae. Aedes mosquitoes were most commonly observed breeding in plastic tanks, tires, and plastic or metal buckets/bowls. World Health Organization entomological indices classified the study site as high risk for dengue virus outbreaks (House Index = 45.2%, Container Index = 49.4%, and Breteau Index = 129). Time series climate data, specifically rainfall, were found to be significantly predictive of AR (p = 0.035). Study findings highlight the importance of vector control to prevent future DF outbreaks in the region. The scarcity of drinking water and microclimatic conditions may have also contributed to the occurrence of this outbreak.

Mycobacterium Tuberculosis and Nontuberculous Mycobacteria Isolates from Presumptive Pulmonary Tuberculosis Patients Attending A Tertiary Hospital in Addis Ababa, Ethiopia.

BACKGROUND: Mycobacterial infections are known to cause a public health problem globally. The burden of pulmonary disease from nontuberculous mycobacteria is reportedly on the rise in different parts of the world despite the fact that there is limited data about the disease in sub-Saharan Africa including Ethiopia. Hence, we aimed to assess the magnitude of M. tuberculosis and nontuberculous mycobacteria (NTM) among presumptive pulmonary tuberculosis patients attending St. Paul's hospital Medical College, Addis Ababa, Ethiopia. METHODS: A cross-sectional study was conducted from June to September 20/2016. Morning sputum specimens were collected, processed and cultured in Lowenstein Jensen medium and BACTEC MGIT 960 media. The nontuberculous mycobacteria were further confirmed and characterized by Genotype CM/AS assays. The socio-demographic, clinical and chest x-ray data were collected using a structured questionnaire. The data was analyzed using SPSS version 20. RESULTS: Out of 275 presumptive tuberculosis patients enrolled in the study, 29(10.5%) were culture positive for Mycobacteria. Of these, 3(10.3%) were found to be NTM and 26(89.6%) were Mycobacterium tuberculosis complex. Of the NTM, two were unidentified and one typed as M.peregrinum. There was no co-isolation of Mycobacterium tuberculosis complex and nontuberculous mycobacteria. Overall, 6(23.1%) Mycobacterium tuberculosis complex isolates were resistant to at least one anti-tuberculosis drug. Of these, two were multidrug resistant tuberculosis cases (7.7%) detected from previously treated patients. CONCLUSION: Relatively low magnitude of Mycobacterium tuberculosis complex and nontuberculous mycobacteria isolates were seen in the study area. Therefore, further study using a large sample size is needed to be done to consider nontuberculous mycobacteria infection as a differential diagnosis in presumptive pulmonary tuberculosis patients.

Perceived organizational culture and its relationship with job satisfaction in primary hospitals of Jimma zone and Jimma town administration, correlational study.

BACKGROUND: The concept of Organizational Culture (OC) which refers to the pattern of values, norms, beliefs, attitudes and assumptions may not be articulated through verbal language. However, it shapes the way people behave and the way things get done in an organization. The management of organizational culture is increasingly viewed as necessary part of health system reform. Major cultural transformation of an organization must be secured alongside structural and procedural changes in order to achieve desired quality and performances improvements in health systems. It is therefore essential to understand organizational culture, job satisfaction level of the health workers and the link between them. METHODOLOGY: Facility based cross sectional study was conducted in four primary hospitals of Jimma zone and town administration. A self-administered questionnaire was used to collect the data. The collected data were checked for completeness, entered and documented into Epi-data version 3.1 and Exported to SPSS version 21 for analysis. Finally descriptive statistics, Paired t-test and multiple linear regression analysis were used to assess the relationship between organizational culture and job satisfaction and the results were presented using tables and charts. RESULT: It was indicated from the finding that, the dominant existing organizational culture typology in the primary hospitals was Hierarchy culture (MS = 22.31, ±2.82).and the preferred organizational culture typology was Innovative culture (MS = 26.09, ±4.72). The health workers had low to medium level of job satisfaction where only (29.40%) of the health workers were very satisfied with their hospital physical working environment. Existing perceived clan culture had positive and significant correlation with health workers' satisfaction in relation to work relation dimension (r = .16, p < 0.002). CONCLUSION: while acknowledging all limitation of observational study we reached to the conclusion that an employees of the respective primary hospitals would prefer to work in environment characterized by innovative and clan culture and their satisfaction level is medium so that the managers should undertake major cultural transformation and must work to improve the job satisfaction level of health workers within their respective hospitals.

The effect of "universal test and treat" program on HIV treatment outcomes and patient survival among a cohort of adults taking antiretroviral treatment (ART) in low income settings of Gurage zone, South Ethiopia.

BACKGROUND: Through universal "test and treat approach" (UTT) it is believed that HIV new infection and AIDS related death will be reduced at community level and through time HIV can be eliminated. With this assumption the UTT program was implemented since 2016. However, the effect of this program in terms of individual patient survival and treatment outcome was not assessed in relation to the pre-existing defer treatment approach. OBJECTIVE: To assess the effects of UTT program on HIV treatment outcomes and patient survival among a cohort of adult HIV infected patients taking antiretroviral treatment in Gurage zone health facilities. METHODS: Institution based retrospective cohort study was conducted in facilities providing HIV care and treatment. Eight years (2012-2019) HIV/AIDS treatment records were included in the study. Five hundred HIV/AIDS treatment records were randomly selected and reviewed. Data were abstracted using standardized checklist by trained health professionals; then it was cleaned, edited and entered by Epi info version 7 and analyzed by STATA. Cox model was built to estimate survival differences across different study variables. RESULTS: A total of 500 patients were followed for 1632.6 person-year (PY) of observation. The overall incidence density rate (IDR) of death in the cohort was 3 per-100-PY. It was significantly higher for differed treatment program, which is 3.8 per-100-PY compared to 2.4 per-100-PY in UTT program with a p value of 0.001. The relative risk of death among differed cases was 1.58 times higher than the UTT cases. The cumulative probability of survival at the end of 1st, 2nd, 3rd, and 4th years was 98%, 90.2%, 89.2% and 88% respectively with difference between groups. The log rank test and Kaplan-Meier survival curve indicated patients enrolled in the UTT program survived longer than patients enrolled in the differed treatment program (log rank X2 test = 4.1, p value = 0.04). Age, residence, base line CD4 count, program of enrolment, development of new OIS and treatment failure were predicted mortality from HIV infection. CONCLUSION: Mortality was significantly reduced after UTT. Therefore, intervention to further reduce deaths has to focus on early initiation of treatment and strengthening UTT programs.

Essential in-vitro laboratory diagnostic services provision in accordance with the WHO standards in Guragae zone primary health care unit level, South Ethiopia.

INTRODUCTION: Laboratory services are crucial parts of the health system having a great contribution to disease prevention and management. The importance of accurate and reliable laboratory test results is less recognized in developing countries like Ethiopia where most medical decisions are based on clinical judgment. It is time for countries like Ethiopia to not only increase health care coverage but also improve access to essential diagnostic tests. Hence, this proposed study aims to assess essential in-vitro laboratory service provision in accordance with the WHO standards in Guragae Zone primary health care unit level, South Ethiopia. METHODS: Health institution-based cross-sectional study was carried out. 30% randomly selected primary health care units were recruited. Each facility was visited with a WHO checklist by a trained data collector to assess the availability of essential diagnostics service provision. The proportion of available in-vitro diagnostics services was calculated. Results were presented as percentages in tables and figures. RESULT: Twenty-one primary health care facilities located in Guragae Zone were assessed between May and July 2019. All surveyed facilities had major gaps in essential test availability. Among essential diagnostic tests listed with WHO like C-reactive protein, lipid profile, Amylase and Lipase, TroponinT/I, hepatitis B e-antigen, IgM-specific antibodies to hepatitis B core antigen, Glucose-6-phosphate dehydrogenase activity, and anti-HIV/p24 rapid test were not provided in any facilities. However, essential diagnostic services like urine dipstick testing, random blood sugar, smear microscopy, and few serological tests were provided at all primary health care units. All surveyed facilities had limited major laboratory equipment and consumables. CONCLUSION AND RECOMMENDATION: The present study shows limited access to essential laboratory tests at the primary health care level. Hence, the responsible body should invest to make essential tests accessible at the primary care unit level within the framework of universal health coverage in the study area. The fact that access to essential diagnostic tests is the first key step in improving quality of care; such study has its own efforts to enable the implementation of essential diagnostic lists, and improve access to diagnostics in the country.

An epidemiological study of visceral leishmaniasis in North East Ethiopia using serological and leishmanin skin tests.

BACKGROUND: In Ethiopia, visceral leishmaniasis (VL) is caused by Leishmania donovani. The estimated country-wide incidence of VL in Ethiopia is 3700-7400 cases/year. The balance between anthroponotic and zoonotic transmission is still unknown even though most authors believe that visceral leishmaniasis in East Africa is anthroponotic. Asymptomatic leishmania infections occur more frequently than clinically apparent visceral leishmaniasis cases. The aim of this study was to determine the prevalence of asymptomatic VL infection and assess the degree of exposure among residents in Raya Azebo Woreda villages where cases of VL were recently reported. METHODS: A community based cross-sectional survey was conducted in 2013 between 1st of May and 25th of July. A total of 1099 individuals living in 314 households were included in the study. Socio-demographic and clinical data were collected from each of the participants and venous blood was also collected for the detection of antibodies to visceral leishmaniasis using Direct Agglutination Test. Leishmanin skin test was performed to detect the exposure to the parasite. Data was entered into excel and exported to SPSS version 17 for statistical analysis. Chi-square and the corresponding p-values were used to determine the statistical significance of the proportions/ratios obtained from the cross tabulated data. A p-value < 0.05 was considered statistically significant. RESULT: A total of 1099 study subjects comprising 401 males and 698 females were included in the study. The overall positive leishmanian skin test and sero-prevalence rates respectively were 9.08% and 0.87%. The difference in LST positivity by age group and sero-prevalence by sex were statistically significant (P <0.01 and P<0.05 respectively). Out of the 9 sero-positive individuals, 7 had no history of travel to visceral leishmaniasis endemic areas out of Raya Azebo. CONCLUSION: In general our results suggest occurrence of VL in the study area is, very low. Our survey also indicates that due to the low incidence of the disease, and lack of awareness, some patients remain under diagnosed.

Impact of annual preventive mass chemotherapy for soil-transmitted helminths among primary school children in an endemic area of Gurage zone: a prospective cross-sectional study.

BACKGROUND AND AIM: School-based preventive mass chemotherapy has been a key component of Ethiopia's national plan for the control of soil-transmitted helminths. Without an impact evaluation on the impact of a deworming program on infection levels, it is unclear whether the deworming program warrants levels of environmental transmission of infection. This study aimed to determine the impact of annual preventive mass chemotherapy for soil-transmitted helminths among schoolchildren in an endemic area of Gurage zone, south-central Ethiopia. METHODS: A repeated school-based quantitative prospective cross-sectional method was employed. Data were collected from study participants selected using systematic sampling with probability proportional to size at baseline and after annual treatment. Fresh stool samples were collected and processed using the Kato─Katz technique at the Wolkite University parasitology laboratory. SPSS-21 was used for data management and analysis. Changes in parasitological variables after treatment were estimated. RESULTS: Overall, 41.1% prevalence and 22.3% mean geometric infection-intensity reduction were found. Reductions in prevalence of Schistosoma mansoni and hookworms were 13.2% and 15.3%, respectively. Similarly, decreases in prevalence were seen in Ascaris lumbricoides and Trichuris trichiura, representing 94.4% and 80.0% reduction rates, respectively, while 25.9% of the children had heavy S. mansoni (≥400 eggs per gram) infections at baseline, which were reduced to 4.5% after annual treatment. Geometric mean infection intensity-reduction rates for hookworms, A. lumbricoides, and T. trichiura were 80.8%, 20.2%, and 96.7%, respectively. CONCLUSION: Annual mass chemotherapy failed to clear soil-transmitted helminths completely in the present study. However, it resulted in a substantial reduction in overall prevalence and infection intensity. Therefore, other than deworming for school children, interventions such as access to improved personal hygiene and environmental hygiene in school should be emphasized to interrupt transmission.

Therapeutic efficacy of chloroquine for treatment of Plasmodium vivax malaria cases in Guragae zone southern Central Ethiopia.

BACKGROUND: Malaria continues to be a public health problem and important cause of morbidity and mortality in Ethiopia. Due to continuous interventions to combat malaria in endemic regions, a decline in malaria related deaths and morbidity has been registered. These gains, however, are threatened with the emergency of antimalarial drugs resistant strains of plasmodium parasites. This study aimed to determine therapeutic efficacy of chloroquine for treatment of Plasmodium vivax malaria cases in Guragae zone, southern central Ethiopia. METHODS: A one arm prospective study with recurrence of parasitaemia and clinical conditions of patients were evaluated on days 0, 1, 2, 3, 7, 14, and 28. Patients with Plasmodium vivax malaria mono infection and eligible for study inclusion criteria were recruited. SPSS-21 used for data analysis and management. Kaplan-Meier survival probability analysis was estimated. Mean geometric parasitaemia and average haemoglobin concentration were calculated. RESULTS: Among 87 total recruited subjects, 81 of them completed the 28 days follow up. More than half of (57.5%) the study participants had a history of fever and 42.5% of them had fever at the time of enrollment. The mean body temperature on day of recruitment was 38.2 °C and 36.8 °C on day 28. Geometric mean parasitaemia calculated on day of enrollment was 2270 parasites/µl of blood. Recurrence of parasitaemia was registered from two subjects during entire follow up. The mean haemoglobin concentration of study participants on day of enrolment was 11.8 g/ dl and 13.8 g/dl on day 28. CONCLUSION: This study registered a high chloroquine efficacy rate among the study participants. Therefore, chloroquine remains efficacious for the treatment of Plasmodium vivax malaria in the study area. However, there is a need to monitor chloroquine resistance by employing molecular tools for better evaluation of treatment outcome.

Fruit and vegetable contamination with medically important helminths and protozoans in Tarcha town, Dawuro zone, South West Ethiopia.

Background: Fresh vegetables supply the body with essential supplements. The consumption of raw vegetables and fruits are among the ways for transmission of intestinal parasitic organisms to human beings. This study was aimed at detecting the parasitic contamination in fresh vegetables sold at the central open-aired market of Tarcha town, Ethiopia. Methods: A total of 270 fresh vegetables and fruit samples were collected from the main market of Tarcha town during August 1, 2017-August 22, 2017. The samples were microscopically examined for detection of medically important parasites after washing with 500 mL normal saline and 24-hr sedimentation of the washing solution followed by centrifuging at 2000 g for 5 mins. After centrifugation, the supernatant was decanted leaving the sediment. Finally, the sediment was examined under a light microscope for protozoans and helminths worms. Results: Of the 270 fresh vegetable and fruit samples, 115 (42.6%) were found positive for intestinal parasites. A high level of contamination in fresh vegetable and fruit samples was recorded in cabbage 71.1% (32/45) while tomato was the least contaminated 24.4% (11/45). The identified medically important parasites were Entamoeba histolytica/dispar, Giardia intestinalis, Ascaris lumbricoides, Hymenolepis nana, Toxocara spp, Hymenolepis diminuta, and Cystoisospora belli. The most predominant parasite encountered was Ascaris lumbricoides (16.7%) whereas Cystoisospora belli (2.6%) the least detected. All of the vegetables and fruits that were contaminated were with more than one parasite species. A statistically significant association between the type of vegetables and the presence of parasites was also observed (p=0.002). Conclusion: This study has shown that fruits and vegetables which are sold in the study area are highly contaminated with medically important parasites. Fruits and vegetables sold in the study area may play a role in the transmission of intestinal parasitic infections to humans. Effective and comprehensive prevention measures should be taken to ensure food safety. Relevant bodies should work on addressing the issue of high rate of vegetable and fruit contamination in the study area.

Effect of iron deficiency anemia on HbA1c in diabetic patients at Tikur Anbessa specialized teaching hospital, Addis Ababa Ethiopia.

BACKGROUND: Hemoglobin A1C (HbA1c) is the predominant hemoglobin found in HbA1 fractions. A1c assay is the recommended assay for diagnosing diabetes and any condition that changes red cell turnover such as Iron deficiency Anemia (IDA), will lead to spurious A1C results. Therefore, the present study was aimed at determining the effect of IDA on HbA1c in diabetic patients attending Black Lion Specialized Teaching Hospital, Addis Ababa, Ethiopia. METHODS: A facility based comparative cross sectional study was conducted on 174 diabetic patients (87 with IDA and 87 without IDA) from April to July 2016. Socio demographic data and clinical conditions were collected using structured questionnaire. Venous blood was collected for performing Complete blood count (CBC) using Cell dyn 1800 hematology analyzer; Serum ferritin, performed by COBAS INTEGRA 400/800 Chemistry analyzer and HbA1c tests, performed by COBAS C 111 analyzer. Data was analyzed using SPSS version 21 software. Pearson's correlation, chi-square, and independent t-tests were calculated. The data was presented as mean ± SD. A P-value of < 0.05 was taken as statistically significant. RESULTS: Mean hemoglobin (Hgb), hematocrit (HCT), Mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC) were lower in IDA group compared to non-IDA diabetic patients. HbA1c (%) level was significantly lower in IDA group (6.18 ± 1.57) compared with the non-IDA diabetic patients (7.74 ± 1.81) (p < 0.05). CONCLUSION: HbA1c is significantly lower in diabetic patients with IDA compared to the non-IDA diabetic patients. Therefore, the authors believe that monitoring these patients using only HbA1c could be misleading, hence physicians and health care providers should take this into account before making any therapeutic decision. Detailed examination including large number of participants employing advanced laboratory techniques is recommended.

Visceral leishmaniasis in selected communities of Hamar and Banna-Tsamai districts in Lower Omo Valley, South West Ethiopia: Sero-epidemological and Leishmanin Skin Test Surveys.

BACKGROUND: Visceral leishmaniasis [VL] is a debilitating parasitic disease which invariably kills untreated patients. The disease is caused by Leishmania (L.) donovani or L. infantum, and transmitted by the bite of female phlebotomine sandflies. VL often remains subclinical but can become symptomatic with an acute/subacute or chronic course. Globally, the Eastern Africa region is one of the main VL endemic areas. The disease is prevalent in numerous foci within Eritrea, Ethiopia, Kenya, Somalia, Sudan South Sudan, and Uganda. In Ethiopia, the Lower Omo plain is one of the many VL endemic regions. OBJECTIVES: The objective of this study was to determine the prevalence of asymptomatic visceral leishmaniasisin Hamar and Banna-Tsamai districts of the South Omo plains where VL is becoming an emerging health problem of neglected communities. METHODS: A community based cross-sectional survey was conducted in 2013 between 25th of July and 14th of August. A total of 1682 individuals living in 404 households were included in the study. Socio-demographic and clinical data were collected from each of the participants and venous blood was also collected for the detection of antibodies to visceral leishmaniasis using Direct Agglutination Test. Leishmanin Skin Test was performed to detect the exposure to the parasite. RESULTS: The surveys included 14 villages located in areas where VL had been reported. In a study population of 1682 individuals, the overall positive leishmanian skin test and sero-prevalence rates respectively were 8.6% and 1.8%. A statistically significant variation in the rate of positive LST response was observed in different study sites and age groups. Positive LST response showed an increasing trend with age. The sero-prevalence rate also showed a statistically significant variation among different study sites. Higher rates of sero-prevalence were observed in children and adolescents. The LST and sero-prevalence rates in Hamar District exceeded significantly that of Banna-Tsamai District (10.7% versus 5.8% for LST; and 2.6% versus 0.7% for sero-prevalence). CONCLUSION: The prevalence of asymptomatic VL infection in Hamar and Banna-Tsamai districts during the study period in 2013 was low compared to rates previously reported in other endemic areas of Ethiopia. This could be due to the fact that the disease is emerging in Hamar and Banna-Tsamai districts. Based on records of a nearby Hospital, increasing numbers of active VL cases have been reported in these districts through the years 2006-2012, especially in Hamar District. Both districts are important destinations of tourism, and thus the importance of surveillance should be emphasized. Detailed epidemiological and entomological studies are recommended.

Parasitic contamination of raw vegetables and fruits collected from selected local markets in Arba Minch town, Southern Ethiopia.

BACKGROUND: One way that people get infected with intestinal parasites is through the consumption of contaminated vegetables and fruits. This study aimed at determining the prevalence and predictors of parasitic contamination of fruits and vegetables collected from four local markets in Arba Minch town, Southern Ethiopia. METHODS: A cross-sectional study was conducted from 1 to 21 September 2014 to determine the level of parasitic contamination of fruits and vegetables sold in Arba Minch town. A total of 360 samples of different types of fruits and vegetables were soaked in physiological saline, followed by vigorous shaking with the aid of a mechanical shaker for 15 minutes and then examined using the sedimentation concentration technique. RESULTS: Out of the 360 samples examined, 196 (54.4%) were contaminated with at least one type of parasite. Ascaris lumbricoides (20.83%) was the most frequently detected parasite and Isospora belli (3.06%) was the least frequently detected one. It was also observed that decreased parasitic contamination was significantly associated with washing the products before displaying it for selling (P < 0.001). CONCLUSIONS: The findings of this study provide evidence that there is a potentially high risk of acquiring parasitic infections from the consumption of raw vegetables and fruits in Arba Minch, Ethiopia. The authors believe that an effort should be made by the relevant bodies to reduce the rate of contamination of products with medically important parasites by educating the vendors and the community.
