Antimicrobial susceptibility pattern of Helicobacter pylori strains isolated from adult dyspeptic patients in Tikur Anbassa University Hospital, Addis Ababa, Ethiopia

Presently, there is no published information on the antimicrobial susceptibility pattern of H. pylori strains in Ethiopia to guide the choice of drug for therapy. Therefore, it is becoming clinically relevant to test the in vitro susceptibility of H. pylori clinical isolates prior to treating patients. Susceptibility testing was performed on 50 clinical H. pylori isolates obtained from adult dyspeptic patients referred to the gastrointestinal (GI) Clinic of Tikur Anbassa University Hospital. Five antibiotics were evaluated, by using the Episolmeter test (E-test). The antibiogram of 50 H. pylori clinical isolates showed that all strains were sensitive to clarithromycin, erythromycin and tetracycline, while 38/50 (76%) and 3/50 (6%) of the strains were resistant to metronidazole and amoxicillin, respectively. Infection by metronidazole or amoxicillin resistant H. pylori is an important factor leading to treatment failure. Testing of all H. pylori clinical isolates to metronidazole and amoxicillin is recommended. If it is not possible to perform susceptibility tests on each clinical isolate, a program to survey the prevalence of resistance should be implemented in a given area or population. When treatment of H. pylori infection is indicated in dyspeptic patients, the potential availability, simplicity of use, safety and low cost of the antimicrobial agents have to be taken into account.     

Hopane-type saponins from the seeds of Glinus lotoides

Four new hopane-type saponins, glinusides F, G, H, and I (1-4), and the known succulentoside B (5), as well as the two known flavones 5,7,4'-trihydroxyflavone-6,8-di-C-glucoside (vicenin-2) and 5,7,4'-trihydroxyflavone-8-C-sophoroside (vitexin-2' '-O-glucoside), were isolated from the seeds of Glinus lotoides growing in Ethiopia. On the basis of the spectroscopic data analysis, including 2D NMR and HRESIMS, the new structures were characterized as 3beta-O-beta-D-xylopyranosyl-6alpha-O-beta-D-xylopyranosyl-16beta-O-beta-D-xylopyranosyl-22-hydroxyhopane (1), 3beta-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-6alpha,16beta-dihydroxy-22-O-alpha-L-rhamnopyranosylhopane (2), 3beta-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyl-6alpha-O-beta-D-xylopyranosyl-16beta-hydroxy-22-O-alpha-L-rhamnopyranosylhopane (3), and 3beta-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-d-xylopyranosyl-6alpha-O-beta-D-xylopyranosyl-16beta-O-beta-D-xylopyranosyl-22-hopane (4).     

Extracranial meningioma of the scalp: case report

A 70-year-old man was admitted with a swelling on the left parietal region, which had grown progressively but slowly for three years. During the last six months the swelling increased in size relatively faster. The lesion was excised totally and sent for pathological examination. The histologic diagnosis was classical meningothelial meningioma. The specimen included some fragments of the skull, however, there was no evidence of an intracranial origin of the tumor. Eighteen months after surgery there was no evidence of recurrence or neurological deficit. Even though primary extracranial meningioma is a rare neoplasm, it should be included in the differential diagnosis of soft tissue tumors above all in the head and neck region.     

Prevalence and associated factors of depression among patients with HIV/AIDS in Hawassa,Ethiopia, cross-sectional study

Background

Globally, 350 million people are affected by depression and 800,000 people die due to suicide every year due to depression. People living with HIV/AIDS face different challenges, including HIV-related perceived stigma, lack of social support and also depression. This study aimed to assess prevalence and factors associated with depressive symptom among people living with HIV/AIDS attending Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia.

Methods

Hospital-based cross-sectional study was implemented in 2016. A total of 401 HIV-positive patients who had regular visit at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia were included in the study. Systematic random sampling technique was used to recruit study participants. Patient Health Questionnaire item nine (PHQ-9) was used to assess depressive symptoms. In addition to this, Oslo social support scale and HIV perceived stigma scale were used to assess social support and HIV-related perceived stigma, respectively.

Results

A total of 401 study participants were included in the study, giving a response rate of 96.2%. The mean age of the respondents was 38 years (SD?±?10.23). This study revealed that 48.6% of HIV-positive patients had depression. Patients who had poor social support [AOR?=?2.53, (95% CI 1.70, 9.13)], HIV-related perceived stigma [AOR?=?2.83, (95% CI 1.78, 4.48)] and CD4 cell count?<?200 [AOR?=?3.89, (95% CI 1.02, 14.83)] were more likely to have depression as compared to individuals who had good social support, no perceived HIV stigma and CD4 cell count?>?200, respectively.

Conclusion

Having poor social support, HIV-related perceived stigma and low CD4 cell count (<?200) had statistically significant association with depressive symptom. Training of health workers in ART clinics and availing manuals on assessing mental health issues is useful to screen and treat depression among HIV patients.

     

Development of the ventral body wall in the human embryo

Migratory failure of somitic cells is the commonest explanation for ventral body wall defects. However, the embryo increases ~ 25‐fold in volume in the period that the ventral body wall forms, so that differential growth may, instead, account for the observed changes in topography. Human embryos between 4 and 10 weeks of development were studied, using amira ^® reconstruction and cinema 4D^® remodeling software for visualization. Initially, vertebrae and ribs had formed medially, and primordia of sternum and hypaxial flank muscle primordium laterally in the body wall at Carnegie Stage (CS)15 (5.5 weeks). The next week, ribs and muscle primordium expanded in ventrolateral direction only. At CS18 (6.5 weeks), separate intercostal and abdominal wall muscles differentiated, and ribs, sterna, and muscles began to expand ventromedially and caudally, with the bilateral sternal bars fusing in the midline after CS20 (7 weeks) and the rectus muscles reaching the umbilicus at CS23 (8 weeks). The near‐constant absolute distance between both rectus muscles and approximately fivefold decline of this distance relative to body circumference between 6 and 10 weeks identified dorsoventral growth in the dorsal body wall as determinant of the ‘closure’ of the ventral body wall. Concomitant with the straightening of the embryonic body axis after the 6th week, the abdominal muscles expanded ventrally and caudally to form the infraumbilical body wall. Our data, therefore, show that the ventral body wall is formed by differential dorsoventral growth in the dorsal part of the body.     

Preterm Neonatal Mortality and its predictors in Tikur Anbessa Specialized Hospital,Addis Ababa,Ethiopia: a retrospective cohort study

BackgroundPreterm neonatal death is a global problem. In Ethiopia, it is still high, and the trend in reduction is slower as compared to child mortality. Preterm neonatal birth is the leading cause. The magnitude and associated factors are also not well documented. Therefore, this study aimed to estimate the incidence of mortality and its predictors among preterm neonates in Tikur Anbesa Specialized Hospital (TASH).MethodsAn institution-based retrospective cohort study was conducted among 604 preterm neonates admitted to Tikur Anbesa Specialized Hospital. Data were collected by reviewing patient charts using systematic sampling with a checklist. The data entry was done using EpiData version 4.2, and analysis was done using Stata Version 14.1. Kaplan-Meier and log-rank tests were used to estimate the survival time and to compare it. Cox proportional hazard was also fitted to identify major predictors. Hazard Ratios (HRs) with 95% Confidence Intervals (CI) were used to assess the relationship between factors associated with the occurrence of death. Finally, statistical significance was declared at p-value < 0.05.ResultsIn this study, a total of 604 patient charts were reviewed; of these, 571 met the inclusion criteria and were recruited to the study. A total of 170(29.7%) preterm neonates died during the follow-up period. The median follow-up time of preterm neonate under the cohort was 21 days (IQR: 4, 27). The incidence rate was 39.1 per 1000-person day. Rural residency (AHR: 1.45 (95% CI: 1.1,4.8)), Maternal diabetic Mellitus (AHR:2.29 (95%CI: 1.43,3.65), neonatal sepsis (AHR:1.62 (95% CI: 1.11,2.37), respiratory distress (AHR:1.54 (95% CI:1.03, 2.31), extreme prematurity (AHR:2.87 (95% CI:1.61, 5.11), and low APGAR score (AHR:3.11 (95% CI:1.79, 5.05) was found to be predictors.ConclusionThe rate of preterm neonatal mortality is still an important problem. Having maternal gestational Diabetic Mellitus, neonatal sepsis, respiratory distress, and low Apgar score were major predictors for preterm neonatal mortality. Therefore, efforts have to be made to reduce the incidence of death and for timely management of mothers with Diabetic Mellitus. Healthcare professionals should also work on early diagnosis and treatment of preterm neonate with sepsis, respiratory distress, and low Apgar score.     

Efficacy of fascia iliaca compartment nerve block as part of multimodal analgesia after surgery for femoral bone fracture

BACKGROUND: Fascia iliaca compartment nerve block(FICNB) has been an established technique for postoperative analgesia after surgery for femoral bone fracture. FICNB is technically easy, effective for postoperative pain control after operation for femoral bone fracture and decreases the complications induced by systemic analgesic drugs. The severity of postoperative pain is affected by genetics, cultural and social factors across the world. In this study we assessed the efficacy of fascia iliaca compartment nerve block when it is used as part of multimodal analgesia after surgery for femoral bone fracture.METHODS: An institution-based case control study was conducted from September, 2013 to May, 2014. All patients who had been operated on under spinal anesthesia for femoral bone fracture were included. The patients divided into a FICNB group(n=20) and a control group(n=20). The FICNB group was given 30 mL of 0.25% bupivacaine at the end of the operation. Postoperative pain was assessed within the f irst 24 hours, i.e. at 15 minutes, 2 hours, 6 hours, 12 hours and 24 hours using 100 mm visual analogue scale(VAS), total analgesic consumption, and the time for the f irst analgesic request.RESULTS: VAS pain scores were reduced within the f irst 24 hours after operation in the FICNB group compared wtih the control group. VAS scores at 2 hours were taken as median values(IQR) 0.00(0.00) vs.18.00(30.00), P=0.001; at 6 hours 0.00(0.00) vs. 34.00(20.75), P=0.000; at 24 hours 12.50(10.00) vs. 31.50(20.75), P=0.004; and at 12 hours(17.80±12.45) vs.(29.95±12.40), P=0.004, respectively. The total analgesic consumption of diclofenac at 12 and 24 hours was reduced in the FICNB group, and the time for the fi rst analgesic request was signifi cantly prolonged(417.50 vs. 139.25 minutes, P=0.000).CONCLUSIONS: A single injection for FICNB could lead to postoperative pain relief, reduction of total analgesic consumption and prolonged time for the fi rst analgesic request in the FICNB group after surgery for femoral bone fracture. We recommend FICNB for analgesia after surgery for femoral bone fracture and for patients with femoral bone fracture at the emergency department.     

Neonatal gastrointestinal surgical emergencies: a 5- year review in a teaching hospital Addis Ababa, Ethiopia

OBJECTIVE: A five year retrospective review of medical records of newborns admitted for gastrointestinal surgical emergencies was done. This study was intended to see the pattern of presentation, mode of intervention and surgical outcome of these cases and for provision of feed-back to the surgeon-pediatrician team who are involved in the care of such newborns. METHODS: The study included cases admitted to the Neonatal Unit of the Department of Pediatrics and Child Health, Tikur Anbessa Specialized Hospital, Addis Ababa, during the period of January 1, 1997 to December 31, 2001. RESULTS: A total of 60 cases admitted during the above-mentioned period were reviewed. Thirty-six (60%) were males, 23 (38%) were females, while one newborn had ambiguous genitalia. Imperforate anus has accounted for 27 (45%) of the 60 cases; jejunoileal atresia and esophageal atresia with or without tracheoesophageal each accounted for 12 (20%) cases; while 9 (15%) had other lesions. Of the 60 cases surgical intervention was performed on 43 (72%) newborns. Of the 12 newborns with esophageal atresia with or with out tracheoesophageal fistula. only one newborn was discharged alive; 7 out of 12 newborns with jejunoileal atresia died, 4 cases discharged improved while the outcome for 1 newborn was not known. Of the newborns with imperforate anus, 8 (47%) of the 17 with the high type and 1 (10%) of the 10 with low-type died CONCLUSION: Early diagnosis, availability of diagnostic service and prompt surgical intervention with optimal pre- and post-operative care are necessary to increase survival of newborns with such problems.
