BackgroundIn spite of the availability and accessibility of HIV testing opportunities and efforts, people are being late to test in the course of HIV infection. Late diagnosis leads to late anti-retroviral therapy initiation which in turn results in poor treatment outcome and prognosis of the disease. The aim of this study was to determine the prevalence and predictors of late HIV diagnosis among HIV-infected patients in South Tigray Zone, Ethiopia.MethodsA facility based cross sectional study was conducted among HIV positive patients from February 1-30, 2014 in Southern Tigray, Ethiopia. Multistage sampling technique was employed to select the study participants. Data were collected by reviewing patient medical card and interviewing using structured questionnaire. Data were entered using Epi-Data version 3.1 and analyzed using SPSS version 20.0. Both bivariate and multivariate logistic regressions were modeled to evaluate the association of predictors with late diagnosis of HIV infection.ResultsOut of 789 study participants, 68.8 % of them were late for HIV diagnosis. Feeling healthy (65.7 %), fear of stigma and discrimination (32.4 %) and using traditional treatment (1.5 %) were reported as the main reasons for late HIV diagnosis. Use of Khat [AOR = 3.27, 95 % CI (1.75, 6.13)], bed ridden functional status [AOR = 2.66, 95 % CI (1.60, 4.42)], ambulatory functional status [AOR = 1.56, 95 % CI (1.03, 2.35)] and Muslim religion [AOR = 2.26, 95 % CI (1.13, 4.49)] were significantly associated with late presentation for HIV diagnosis.ConclusionsHigh prevalence of late HIV diagnosis was recorded in Southern Tigray Zone, Ethiopia. Public health educations and campaigns targeted at improving early diagnosis and prognosis of people living with HIV/AIDS in Southern Tigray, Northern Ethiopia should be underway.

Introduction. Irrational prescribing is a major cause for irrational drug use. Bad prescribing habits lead to ineffective and unsafe treatment, exacerbation or prolongation of illness, distress and harm to the patient, and higher costs. Incidence of irrational prescribing practice cannot be reduced without a critical intervention by assessing the causes. Objectives. The objective of this study was to assess drug prescription pattern, using WHO prescribing indicators, in OPD at Mekelle General Hospital (MGH) Methodology. The study was conducted at Mekelle General Hospital (MGH), Mekelle, Northern Ethiopia, from December 2016 to April 2017. A descriptive cross-sectional, retrospective hospital-based study design was used to assess prescriptions at OPD in MGH from 01 January to 31 December 2016. A systematic random sampling technique was used to select prescriptions at the time of data collection. Result. 384 prescriptions were analyzed. 751 medications were prescribed from which 679 (90.4%) were with their generic name, 225 (58.6%) prescriptions contained antibiotics, 162 (42.2%) prescriptions were encountered with injection, and 648 (86.3%) encountered from the hospital list of medicine. Conclusion. In general, average number of drugs per encounter, generic prescribing, and the use of EDL/formulary of the hospital to prescribe drugs reviewed in this study were totally out of the recommended values and hence inappropriate. The study also revealed overprescribing of both antibiotics and injections.

Introduction. Irrational medicine use is a global problem, and one of its manifestation is inappropriate prescribing that occurs when medicines are not prescribed in accordance with the guideline. Objective. The aim of the study was to assess prescription completeness and drug use pattern of the hospital using the WHO core drug use indicators. Methods. 1000 prescriptions were collected retrospectively from prescriptions written for 1 year from outpatient pharmacies of the hospital. Exit interview was employed to assess patient care indicators. The health facility indicators were checked by assessing the presence of drug formulary and availability of key medicines at the facility. Data were analyzed using SPSS version 20. Results. It was found that only name of the patients was filled in all the prescriptions. Other informations were below the standard. The average number of drugs per prescription was 1.65. Percentages of encounter by generic name, with antibiotic and injections, were 85.78%, 41%, and 25%, respectively. The percentage of drugs prescribed from an essential drug list was 98.48%. The mean consultation time and dispensing time were 14.49 and 2.16 minutes, respectively. More than half patients had knowledge on drug dispensed to them (68%). The percentage of drugs actually dispensed was 65%, but none of the drugs dispensed were adequately labelled. A copy of EDL and 84% of the key drugs were available in the hospital. Conclusion. From the results of our study, it can be concluded that all prescriptions were not complete, and except the average number of drugs prescribed per encounter, the other drug use pattern indicators were out of the WHO recommendation. Therefore, effective intervention program, like training, for promotion of rational drug use practice was recommended.

Ensete ventricosum (Welw.) cheeseman which belongs to the family of Musaceae is one of the main sources of starch in Ethiopia. This study aimed at evaluating epichlorohydrin cross-linked enset starch as a drug release sustaining excipient in microsphere formulations of theophylline. Extracted enset starch was cross-linked using epichlorohydrin as a cross-linking agent. The effect of cross-linker concentration, cross-linking duration, and cross-linking temperature on the degree of cross-linking and release rate of microspheres prepared by emulsion solvent evaporation method was investigated using the two-level full factorial design. Accordingly, the concentration of epichlorohydrin and duration of cross-linking were the most significant factors affecting both the degree of cross-linking and drug release rate. Thus, the effects of these two factors were further studied and optimized using the central composite design. As per the numerical method of central composite design, the optimal points were obtained at epichlorohydrin concentration of 13.70% and cross-linking time of 3.82 h. Under these optimal conditions, the model predicts the degree of cross-linking of 74.70% and drug release rate of 28.00 h1/2. The validity of these optimal points was confirmed experimentally. The microspheres of the optimum formulation also exhibited minimum burst release with sustained release for 12 h. Besides, the optimized formulation followed the Higuchi square root kinetic model with non-Fickian diffusion release mechanism. The finding of this study suggested that cross-linked enset starch can be used as an alternative drug-release-sustaining pharmaceutical excipient in microsphere formulation.
