The objective of this work was to describe the epidemiological, clinical and paraclinical aspects of viral hepatitis B and c in the internal medicine department of Kara University Hospital. Method: this was a retrospective descriptive study carried out in the Internal Medicine department of Kara University Hospital, over a period of 3 years from March 2020 to April 2023. It included all patients seen in consultation or hospitalized for hepatitis viral B and/or C. Results: A total of 57 patients were included in our study. The average age was 44.30 years ± 16.75 and the M/F sex ratio was 1.38. Married people were in the majority 63.2%. The circumstances of the discovery of viral hepatitis B and C were dominated by abdominal pain in 35.1% of cases and hepatomegaly in 29.8% of cases and in 33.3% of cases, it was during screening voluntary. Patients with viral hepatitis B only accounted for 64.9% of cases;those with only viral hepatitis C represented 31.6% of cases and 3.5% of cases had HVB/HCV co-infection. We recorded 36.8% complications including 52.4% liver cirrhosis and 47.6% hepatocellular carcinomas. During the evolution, there were 03 deaths. Conclusion: the prevalence of hepatitis B and C virus carriage in patients followed in internal medicine at Kara University Hospital is high. It is therefore essential to put in place treatment and prevention strategies against these viruses.展开更多

USLE was governed by five factors include soil erodibility factor (K), rainfall and runoff erodibility index (R), crop/vegetation and management factor (C), support practice factor (P) and slope length-gradient factor (LS). In the past, K, R and LS factors are extensively studied. But the impacts of factors C and P to outfall Total Suspended Solid (TSS) and % reduction of TSS are not fully studied yet. Therefore, this study employs Buffer Zone Calculator as a tool to determine the sediment removal efficiency for different C and P factors. The selected study areas are Santubong River, Kuching, Sarawak. Results show that the outfall TSS is increasing with the increase of C values. The most effective and efficient land use for reducing TSS among 17 land uses investigated is found to be forest with undergrowth, followed by mixed dipt. forest, forest with no undergrowth, cultivated grass, logging 30, logging 10^6, wet rice, new shifting agriculture, oil palm, rubber, cocoa, coffee, tea and lastly settlement/cleared land. Besides, results also indicate that the % reduction of TSS is increasing with the decrease of P factor. The most effective support practice to reduce the outfall TSS is found to be terracing, followed by contour-strip cropping, contouring and lastly not implementing any soil conservation practice.展开更多

The Revised National TB Control Programme (RNTCP) has introduced universal drug susceptibility testing (UDST) for all diagnosed TB cases in 2018. We conducted this study to know the advantage of implementing UDST when compared to selective testing existent in 2017 on key diagnostic cascade parameters and to identify the challenges in the implementation of UDST. Methods: The study was conducted in two districts of Karnataka, India during January 2017-December 2018. The quantitative part consisted of before-and-after design and the qualitative part consisted of descriptive design. Results: In 2017 (during selective testing/“before” period) out of the 2440 TB patients, 80 (3%) were diagnosed with Isoniazid and Rifampicin resistance patients;in contrast in 2018 (during UDST/“after” period) of the 5129 TB patients 258 (5%) were diagnosed with Isoniazid and Rifampicin resistance. However, the proportion of eligible patients tested for rifampicin resistance during the “after” period was 60% when compared to 100% during the “before” period and median turnaround time for testing was also longer during the “after” period when compared to the “before” period (32.5 days vs 27.5 days). Major reasons for these two gaps were found to be difficulties in collecting sputum specimens and transportation. Conclusion: The rollout of UDST has led to a three-fold increase in a number of DR-TB cases detected in the region. There is a need for the programme to increase the proportion tested for DST by increasing the laboratory capacity and address the challenges in sputum collection and transportation.展开更多
