Abstract Background HIV/AIDS is a major public health problem in Ethiopia. University students are often a young and sexually active group that is at risk of acquiring and transmitting HIV. We assessed risky HIV sexual behaviors and utilization of voluntary counseling and testing services among undergraduate students at Addis Ababa Science and Technology University, Ethiopia. Methods A cross-sectional study was conducted between May and June, 2013. Standardized semi-structured self-administered questionnaire was used to collect data. Simple random sampling technique was use to select departments from each school. All students in the selected departments were the study participants. Data were entered into EPI-Info and analyzed using SPPS statistical packages. P-value

Objective/background: The World Health Organization (WHO) declared tuberculosis (TB) as a global public health emergency and recommended directly observed treatment, short-course (DOTS) as a standard strategy to control the disease. In Ethiopia the strategy was started in 1992 as a pilot in the Arsi and Bale zone, Oromia Region. The DOTS strategy has been subsequently scaled up in the country and implemented at a national level reaching better coverage, although there are recognizable variations from region to region and district to district. The aim of this study was to assess the impact of the DOTS strategy on smear-positive pulmonary TB case findings and their treatment outcomes in the Afar Regional State, Ethiopia, from 2003 to 2012 and from 2002 to 2011, respectively. Methods: A health facility-based retrospective study was conducted. Data were collected and reported on a quarterly basis using the WHO reporting format for TB case findings and their treatment outcomes from all DOTS-implementing health facilities in all zones of the region to the Federal Ministry of Health. Results: A total of 34,894 of TB cases had been registered in the period from 2003 to 2012. Out of these, 11,595 (33.2%) were smear-positive pulmonary TB, 13,859 (39.7%) smear-negative pulmonary TB, and 9838 (28.2%) extrapulmonary TB. The case detection rate (CDR) of smear-positive pulmonary TB had increased from 18.3% to 37.2%, with the average value being 32% (standard deviation = 6.8) from the total TB cases to its peak of 39% in 2008. The treatment success rate (TSR) had an average value of 86.2% from 2002 to 2011 with its peak value being 96.5% in 2007. Moreover, the average values of treatment defaulter and treatment failure rate were 2.9% and 2.7%, respectively. Conclusion: The implementation for the DOTS strategy in the area improved the CDR of smear-positive TB, although it is unacceptably lower than the recommended WHO target of 70%. Additionally, the WHO target of 85% for TSR had already been achieved in the region. However, continued efforts should be in place to increase the CDR and maintain the high TSR registered.

OBJECTIVES:Quality of tuberculosis (TB) microscopy diagnosis is not a guarantee despite implementation of External Quality Assurance (EQA) service in all laboratories of health facilities. Hence, we aimed at evaluating the technical quality and the findings of sputum smear microscopy for acid fast bacilli (AFB) at health centers in Hararge Zone, Oromia Region, Ethiopia. METHODS:A cross-sectional study was carried out between July 8, 2014 and July 7, 2015.A pre-tested structured questionnaire was used to collect data. Lot Quality Assurance Sampling (LQAS) method was put into practice for collecting all necessary sample slides. Data were analyzed by using SPSS (Statistical Package for Social Sciences) version 20 software. P-value < 0.05 was considered as statistically significant. RESULTS:Of the total55 health center laboratories which had been assessed during the study period, 20 (36.4%) had major technical errors; 13 (23.6%) had 15 false negative results and 17 (30.9%) had 22 false positive results. Moreover, poor specimen quality, smear size, smear thickness, staining and evenness were indicated in 40 (72.7%), 39 (70.9%), 37 (67.3%), 27(49.1%) and 37 (67.3%) of the collected samples, respectively. False negative AFB findings were significantly associated with lack of Internal Quality Control (IQC) measures (AOR (Adjusted Odds Ratio): 2.90 (95% CI (Confidence Interval): 1.25,6.75) and poor staining procedures (AOR: 2.16(95% CI: 1.01, 5.11). CONCLUSIONS:The qualities of AFB smear microscopy reading and smearing were low in most of the laboratories of the health centers. Therefore, it is essential to strength EQA program through building the capacity of laboratory professionals.

Sepsis is one of the major causes and predictors of death in patients with visceral leishmaniasis (VL). Globally, incidence rate of sepsis ranged from 56–91 cases per 100 000 people, with a mortality rate of 30%. Incidence of sepsis has been raised due to aging of the population and the higher incidence of immunosuppressive conditions such as HIV, VL and others. The prevalence of sepsis was reported from 4.2% to 32.3% and 14.1% in VL and VL-HIV coinfected patients, respectively. The mortality rate of VL patients with sepsis is greater than 50%. Factors associated with sepsis in VL patients are immune suppression, pancytopenia, HIV co-infection, age 40 years old, indwelling of central venous lines and hospitalization. Although antimicrobial susceptibility patterns were not well reported, both Gram-positive and Gram-negative bacteria were isolated from patients with VL. So far, limited information is available on sepsis in VL, especially in VL-HIV coinfected patients. Therefore, further studies about sepsis prevalence, causative agents and their antibiotic patterns, and associated factors among VL and VL-HIV coinfected patients are necessary. This review provides information about bacterial sepsis in patients with VL.

Ten targeted health facilities supported by Damien Foundation (a Belgian Non Governmental Organization) and the National Tuberculosis (TB) Program in Conakry, Guinea.To uphold TB program performance during the Ebola outbreak in the presence of a package of pre-emptive additional measures geared at reinforcing the routine TB program, and ensuring Ebola infection control, health-workers safety and motivation.A retrospective comparative cohort study of a TB program assessing the performance before (2013) and during the (2014) Ebola outbreak.During the Ebola outbreak, all health facilities were maintained opened, there were no reported health-worker Ebola infections, drug stockouts or health staff absences. Of 2,475 presumptive pulmonary TB cases, 13% were diagnosed with TB in both periods (160/1203 in 2013 and 163/1272 in 2014). For new TB, treatment success improved from 84% before to 87% during the Ebola outbreak (P = 0.03). Adjusted Hazard-ratios (AHR) for an unfavorable outcome was alwo lower during the Ebola outbreak, AHR = 0.8, 95% CI:0.7-0.9, P = 0.04). Treatment success improved for HIV co-infected patients (72% to 80%, P

Bacteremia due to Shigella is rare. A 26-year-old HIV-negative male presented with a persistent high-grade fever of two months duration to the Leishmaniasis Research and Treatment Center of University of Gondar Hospital. He was anorexic and had lost significant weight (from 76 to 57 kg in 4 months, BMI = 17.2 kg/m2). He also complained of headache, chills, and rigor. In the last one year, he was experiencing a few episodes of acute bloody diarrhea, the last episode being two months ago. Microscopy from splenic aspiration showed Leishman-Donovan bodies with parasite load of +3. The blood culture showed Shigella species, but the stool was culture negative. The isolate was sensitive to most tested antibiotic discs, sulfamethoxazole, ceftriaxone, gentamicin, tetracycline, and norfloxacilin, except ampicillin. Therefore, requesting blood culture for identifying unexpected type of organisms causing infections in patients with underlying diseases like visceral leishmaniasis should be encouraged.
