Most presentations of conjunctivitis are acute. Studies show that uncomplicated cases resolve within 14 days without medication. However, antibiotic prescription remains standard practice. With antimicrobial resistance becoming a public health concern, we undertook this study to assess antibiotic prescription patterns in managing acute conjunctivitis in an eye hospital in Ghana. We recorded 3708 conjunctivitis cases; 201 were entered as acute conjunctivitis in the electronic medical records (January to December 2021). Of these, 44% were males, 56% were females, 39% were under 5 years, 21% were children and adolescents (5–17 years) and 40% were adults (≥18 years). A total of 111 (55.2%) patients received antibiotics, of which 71.2% were appropriately prescribed. The use of antibiotics was more frequent in children under 17 years compared to adults (p < 0.0001). Of the prescribed antibiotics, 44% belonged to the AWaRe “Access” category (Gentamycin, Tetracycline ointment), while 56% received antibiotics in the “Watch” category (Ciprofloxacin, Tobramycin). Although most of the antibiotic prescribing were appropriate, the preponderance of use of the Watch category warrants stewardship to encompass topical antibiotics. The rational use of topical antibiotics in managing acute conjunctivitis will help prevent antimicrobial resistance, ensure effective health care delivery, and contain costs for patients and the health system.

Antimicrobial Resistance (AMR) and Healthcare Associated Infections (HAIs) are major global public health challenges in our time. This study provides a broader and updated overview of AMR trends in surgical wards of Mulago National Referral Hospital (MNRH) between 2014 and 2018. Laboratory data on the antimicrobial susceptibility profiles of bacterial isolates from 428 patient samples were available. The most common samples were as follows: tracheal aspirates (36.5%), pus swabs (28.0%), and blood (20.6%). Klebsiella (21.7%), Acinetobacter (17.5%), and Staphylococcus species (12.4%) were the most common isolates. The resistance patterns for different antimicrobials were: penicillins (40–100%), cephalosporins (30–100%), β-lactamase inhibitor combinations (70–100%), carbapenems (10–100%), polymyxin E (0–7%), aminoglycosides (50–100%), sulphonamides (80–100%), fluoroquinolones (40–70%), macrolides (40–100%), lincosamides (10–45%), phenicols (40–70%), nitrofurans (0–25%), and glycopeptide (0–20%). This study demonstrated a sustained increase in resistance among the most commonly used antibiotics in Uganda over the five-year study period. It implies ongoing hospital-based monitoring and surveillance of AMR patterns are needed to inform antibiotic prescribing, and to contribute to national and global AMR profiles. It also suggests continued emphasis on infection prevention and control practices (IPC), including antibiotic stewardship. Ultimately, laboratory capacity for timely bacteriological culture and sensitivity testing will provide a rational choice of antibiotics for HAI.

Introduction: Intestinal parasites have an insidious impact on human health. In response to high parasite frequencies in Northwest Ethiopia, mass drug administration (MDA) is provided for school children using albendazole/mebendazole (since 2007) and praziquantel (since 2015). The study objective was to assess trends and seasonal patterns of intestinal parasite infections in a context of MDA. Methodology: This was a descriptive study collecting routine data from laboratory registers in two health centres in Denbia district, Amhara region. Stool test results (wet-mount direct microscopy) from patients attending these centres between 2013 and 2018 were included. Frequencies of different parasite species were evaluated within and across the years and stratified by age and gender. Results: From a total of 8002 stool test results, the overall parasite frequency was 53.3%; this proportion remained constant. The most frequently diagnosed soil-transmitted helminths (STH) were Ascaris lumbricoides (16.9%) and hookworm (3.9%). STH frequency varied over the years, but was similar at the beginning (20.0%) and the end (22.0%) of the six-year period. STH infections were more frequent in winter (December-February; 20.4%) than in other seasons (16.0%). The most frequently diagnosed protozoa were Entamoeba histolytica/dispar (18.5%) and Giardia lamblia (12.2%). The frequency of Giardia steadily increased from 9.6% in 2013 to 15.3% in 2018. E. histolytica/dispar peaked in summer and G. lamblia in autumn. Conclusions: Trends in routine laboratories may be a proxy for a status quo in the community. These findings suggest that higher MDA coverages and/or interventions beyond MDA are needed to reduce intestinal parasite-related morbidity.

Introduction: Timely and appropriate management of snakebites in the tropics is a lifesaver. Many snakebite patients are being bitten in remote rural areas and do not manage to get in due time to healthcare facilities. This study assessed the clinical features and the risk factors associated with treatment outcomes of snakebite patients admitted at two hospitals in the Northwest of Ethiopia. Methodology: In a retrospective cohort study, routinely collected data from 250 patients’ medical charts at University of Gondar Hospital and Metema Hospital, between September 2012 and August 2020, were reviewed. Results: The median age of the snakebite cases was 24 years (95% CI = 22-26), with 80.8% male patients. At admission 148/250 patients presented in Clinical stage 1 or 2 (local symptoms only) and 73.7% presented more than 12 hours after the bite, 80.2% received antibiotics and 79.0% antivenom. The median duration of hospitalization was 3 days (95% CI = 3-4); 72% of the patients recovered and were discharged, 10.8% died and 0.5% underwent an amputation. On logistic regression analysis, residence in rural areas (AOR = 2.52, 95 % CI = 1.2-5.3), sign of bacterial superinfection on the bite site (AOR = 4.69. 95% CI = 1.4-15.4), clinical stage 3 or 4 with systemic symptoms or toxic signs at admission (AOR = 4.84, 95% CI = 1.3-18.0) and no treatment with antivenoms (AOR = 6.65, 95% CI = 1.6-27.7) were associated with bad outcome (death, amputation and/or referred/ went against medical advice). Conclusions: Timely presentation at early clinical stage, appropriate clinical management and availability of antivenoms are cornerstones to reduce snakebite morbidity and mortality.

This study evaluated the effectiveness of an electronic system for managing individuals with drug-sensitive pulmonary tuberculosis in the Kyrgyz Republic. This cohort study used programmatic data. The study included people registered on the paper-based system in 2019 and 302 people registered on both the electronic and the paper-based systems between June 2021 and May 2022. The data from the 302 individuals were used to assess the completeness of each form of record and the concordance of the electronic record with the paper-based system. This study showed that for most variables, the completeness and concordance were 85.3–93.0% and were lowest for nonmandatory fields such as medication side effects (26.8% vs. 13.6%). No significant difference was observed in the time taken from symptom onset to diagnosis and treatment initiation between the two systems. However, the electronic system had a significantly higher percentage of subjects who initiated treatment on the day of diagnosis (80.3% vs. 57.1%). The proportion with successful outcomes was similar in both groups, but the electronic system had a significantly lower proportion of individuals with outcomes that were not evaluated or recorded (4.8% vs. 14.3%, p < 0.001). This study highlights the potential advantages and gaps associated with implementing an electronic TB register system for improving records.

Introduction: Schistosomiasis is one of the Neglected Tropical Diseases in Ethiopia. Since 2015, yearly school-based mass drug adminishation (MDA) using praziquantel has become the major control strategy. This study aimed to assess trends of Schistosoma mansoni infection in a high-endemic area in Northwest Ethiopia. Methodology: Data were extracted from routine laboratory logbooks at two health centers in West Dembia district, Amhara region, for the period 2013-2018. Wet-mount direct microscopy was used to diagnose intestinal parasites. Chi-square test was used to compare proportions of S. mansoni-positive results before and after the start of MDA with praziquantel, across sex, age groups, and seasons. Results: Data of 8002 stool tests was extracted. The proportion of S. mansoni progressively decreased from 9.6% in 2013 to 4.1% in 2018 in the overall patient population and from 20.3% in 2013 to 8.8% in 2018 in school-aged children. However, a declining trend of S. mansoni was observed before the launch of MDA and remained constant after the start of the MDA. The positivity rate was significantly higher in males and in the 5-14 years age group. S .mansoni infection in school aged children showed significant seasonal variation. Conclusions: The declined trend of S. mansoni positivity rate is encouraging and may be related to the existence of intervention packages. Although the timing of MDA was related with low positivity rate of S. mansoni infection, it has not resulted in the expected beneficial effect. Therefore, the district health office should work on both MDA and other interventions.
