Trapped Rotablation Wire Causing Longitudinal Stent Deformation

Longitudinal stent deformation is a recently described complication of percutaneous coronary intervention. It can lead to serious adverse outcomes. The precipitating mechanisms and treatment strategies have been described. We report a case of longitudinal stent deformation that occurred with the removal of a trapped rotablation guide wire.     

Management of traumatic arterio-venous fistulas,experience in Armed Forces General Hospital,Addis Ababa

In Armed Forces General Hospital from March to December 1999, 53 patients were operated for Arterio-venous fistula. All were males, their age ranging from 19 to 46 years, average 27 years. The diagnosis of arterio-venous fistulas was established clinically. The pathological distribution of the lesions were: 23(43.4%) Arterio-Venous aneurysm; 11(20.75%) Arterio-Venous fistula, 19(35.85%) Arterial false aneurysms. The anatomical location was: 15 femoral, 10 Tibial, 6 poplitial, 6 brachial, 4 Axilláry, 1 ulnar, 7 external carotid and 1 occipital. The types of surgical procedures performed were: 29 (54.72%) excision of the arterio-venous fistula and aneurismal sac with arterial restoration by end to end anastomosis and/or saphenous vein graft, 16(30.19%) by excision of arteriovenous fistula and quadriple ligation of small vessels, 8(15.09%) excision of the false aneurismal sac and lateral repair of the artery (lateral arterioraphy). During the post operative period the patients were followed for three months, and we had the following results based on the clinical outcome criteria; 37(69.81%) excellent, 15(28.3%) good and 1(1.89%) fair.     

Kangaroo mother care: a randomized controlled trial on effectiveness of early kangaroo mother care for the low birthweight infants in Addis Ababa, Ethiopia

A randomized controlled trial was conducted over a 1-year period (November 2001-November 2002) in Addis Ababa to study the effectiveness of early Kangaroo mother care before stabilization of low birthweight infants as compared with the conventional method of care. There were 259 babies weighing less than 2000 g during the study period and a total of 123 (47.5 per cent) low birthweight infants were included in to the study. Sixty-two infants were enrolled as Kangaroo Mother Care (KMC) and the remaining 61 were Conventional Method of Care (CMC) cases. The demographic and socioeconomic characteristics for both groups were comparable. The mean age at the time of enrollment was 10 and 9.8 h for KMC and CMC, respectively (p>0.05 with 95 per cent confidence interval). The mean birthweight was 1514.8 g (range 1000-1900 g) for KMC and 1471.8 g (range 930-1900 g) for CMC (p>0.05 with 95 per cent CI) and the mean gestational age was 32.42 and 31.59 weeks for KMC and CMC cases, respectively. Fifty-eight per cent of KMC and 52 per cent of CMC cases were on i.v. fluid. Twenty-one of 62 (34 per cent) of KMC and 23/61 (37 per cent) of CMC babies were on oxygen through nasopharyngeal catheter. The mean age at exit from the study was 4.6 days for KMC and 5.4 days for CMC. Ninety-one per cent and 88 per cent of babies in KMC and CMC were discharged from the study in the first 7 days of life, respectively. The study showed that 14/62 (22.5 per cent) of KMC vs. 24/63 (38 per cent) CMC babies died during the study (p<0.05 and CI of 95 per cent.) The majority of deaths occurred during the first 12 h of life. Survival for the preterm low birthweight infants was remarkably better for the early kangaroo mother care group than the babies in the conventional method of care in the first 12 h and there after. More than 95 per cent of mothers reported that they were happy to care for their low birthweight babies using the early Kangaroo mother method. It was recommended to study the feasibility and effectiveness of Kangaroo mother care at the community level.     

Pneumocystis jiroveci pneumonia and other pulmonary infections in TB smear-negative HIV-positive patients with atypical chest X-ray in Ethiopia

Pneumocystis pneumonia (PCP) has been considered a rare disease in sub-Saharan Africa. However, a rising prevalence has been noted recently. The objective of this study was to determine the relative prevalence of PCP and other pulmonary opportunistic diseases in patients infected with HIV in Ethiopia. 131 consecutive patients with respiratory symptoms and atypical chest X-ray, who were sputum smear-negative for AFB and seroreactive for HIV, underwent clinical evaluation and investigation for Pneumocystis jiroveci and Mycobacterium tuberculosis from sputum and bronchoalveolar lavage (BAL), and fungal and bacterial pathogens from BAL alone. Bacterial infections, Pneumocystis pneumonia (PCP) and pulmonary tuberculosis (PTB) occurred in 44 (33.6%), 39 (29.7%) and 31 (23.7%) patients, respectively. Pulmonary Kaposi sarcoma and non-specific interstitial pneumonitis occurred in 4 patients each. In a multivariate regression model, predictors of PCP were typical chest X-ray and low CD4 count while purulent sputum predicted bacterial infection. The sensitivity of physicians and chest X-ray diagnosis was particularly low for PTB and bacterial infections. We conclude that chronic bacterial infection and Pneumocystis pneumonia are important differential diagnoses in HIV-infected, smear-negative PTB patients presenting with atypical chest X-ray. We therefore need to escalate the use of preventive and highly active antiretroviral (HAART) treatment in order to prevent a PCP epidemic.     

H-type tracheoesophageal fistula

We are reporting a case of a newborn infant who was admitted to the Neonatal unit of the Tikur Ambessa Hospital. The baby was diagnosis to have H-type tracheoesophageal fistula. The patient presented with choking, coughing and sneezing during breast-feeding. The definitive diagnosis was made by Fluoroscopy guided Barium swallow X ray at the age of 21 days. Surgical intervention was done and the baby was discharged in good condition.     

Adverse birth outcomes and associated factors among mothers who delivered in Bale zone hospitals,Oromia Region,Southeast Ethiopia

ObjectiveAdverse birth outcomes, which include stillbirth, preterm birth, low birthweight, congenital abnormalities, and stillbirth, are the leading cause of neonatal and infant mortality worldwide. We assessed adverse birth outcomes and associated factors among mothers who gave birth in Bale zone hospitals, Oromia, Southeast Ethiopia.MethodsWe used systematic random sampling in this cross-sectional study. We identified factors associated with adverse birth outcomes using bivariate analysis and multivariable logistic regression analysis.ResultsThe proportion of adverse birth outcomes among participants was 21%. Of 576 births, 70 (12.2%) were low birthweight, 49 (8.5%) were preterm birth, 45 (7.8%) were stillbirth, and 18 (3.1%) infants had congenital anomalies. Inadequate antenatal care (adjusted odds ratio [AOR] = 6.58, 95% confidence interval [CI] 3.25–13.32), multiple pregnancy (AOR  =  4.74, 95% CI 1.55–14.45), premature rupture of membranes in the current pregnancy (AOR = 2.31, 95% CI 1.26–4.21), hemoglobin level  < 11 g/dL (AOR = 3.22, 95% CI 1.85–5.58), and mid-upper arm circumference less than 23 cm (AOR = 5.93, 95% CI 3.49–10.08) were all significantly associated with adverse birth outcomes.ConclusionsApproximately one in five study participants had adverse birth outcomes. Increasing antenatal care uptake, ferrous supplementation during pregnancy, and improving the quality of maternal health services are recommended.     

Ultrasound evaluation of abdominal masses in Ethiopian child patients

The aim of this study was to assess the pattern of abdominal masses and evaluate the value of ultrasound in paediatric abdominal masses. We used a cross-sectional study of abdominal masses in children attending a university teaching hospital. The common abdominal masses were: Wilms' tumour, 12 (14.8%); lymphoma, 11 (13.6%); appendiceal mass/abscess, 11 (13.6%); neuroblastoma, 7 (8.6%); TB, 6 (7.4%); hydronephrosis, 5 (6.2%); abdominal wall abscess, 6 (7.4%); hydatidcyst, 4 (4.9%); mesenteric cyst, 3 (3.7%); and intussusceptions, 3 (3.7%). Identification of a purely cystic mass was suggestive of benign lesion (odds ratio [OR] = 118, P = 0.0001) and masses found in the <5 years age group tend to be malignant (OR = 2.77). The most common sites of origin were kidneys, retroperitoneal extra renal and gastrointestinal tract. The overall diagnostic accuracy of ultrasound was 88.9%.
