Right Pulmonary Artery Absence or Discontinuity in Ethiopian Toddler

BackgroundUnilateral pulmonary artery absence or discontinuity is a rare congenital abnormality. Its reported prevalence is 1 in 150,000 adults.Case PresentationA 22-month-toddler girl was referred from a general hospital for cardiac follow-up to our hospital after diagnosis of severe pulmonary hypertension was made. She presented with generalized body swelling, cough, fast breathing and high-grade fever of four days duration. She had repeated severe chest infections. Echocardiography and chest computed tomography revealed right pulmonary artery discontinuity. Acute care was given and chronic care was established.ConclusionPulmonary artery discontinuity is a rare anomaly. It should be considered in any child presenting with recurrent chest infections/pulmonary hypertension. Appropriate and timely diagnostic work up will avoid misdiagnosis.     

Diagnosing Hypertension by Intradialytic Blood Pressure Recordings

Background and objectives: The diagnosis of hypertension among hemodialysis patients by predialysis or postdialysis blood pressure (BP) recordings is imprecise and biased and has poor test-retest reliability. The use of intradialytic BP measurements to diagnose hypertension is unknown.Design, setting, participants, & measurements: A diagnostic-test study was done with interdialytic ambulatory BP as reference standard. Index BP recordings tested were: predialysis (method 1), postdialysis (method 2), intradialytic (method 3), intradialytic including predialyis and postdialysis (method 4), and the average of predialysis and postdialysis (method 5). Each index BP was recorded over six consecutive dialysis treatments.Results: There were differences among index BP measurements in reproducibility, bias, precision, and accuracy. Method 4 was the most reproducible (intraclass correlation coefficient = 0.70 for systolic and diastolic BP). All 5 measurement methods overestimated 44-h ambulatory systolic BP. Methods 2, 3, or 4 overestimated ambulatory systolic BP by only a small amount. Method 4 was the most precise and accurate. For diagnosis of hypertension, BP cut-point by method 4 of 135/75 mmHg, had a sensitivity of 90.4% and specificity of 75.9% for systolic BP (area under ROC curve 0.90). Median cut-off systolic BP of 140 mmHg from a single dialysis provides approximately 80% sensitivity and 80% specificity in diagnosing systolic hypertension; a median cut-off diastolic BP of 80 mmHg provides approximately 75% sensitivity and 75% specificity in diagnosing diastolic hypertension.Conclusions: Consideration of intradialytic BP measurements together with predialysis and postdialysis BP measurements improves the reproducibility, bias, precision, and accuracy of BP measurement compared with predialysis or postdialysis measurements.The diagnostic and prognostic significance of hypertension among hemodialysis patients continues to be debated (1,2). Whereas many have suggested that blood pressure (BP) recordings are of little value in managing cardiovascular risk (3,4), others have argued that BP control is important (2,5,6). The accurate measurement of arterial pressure is the essential first step in managing this cardiovascular risk factor, yet the diagnosis of hypertension in hemodialysis patients continues to be a vexing problem (7,8).Although home BP monitoring is a superior tool to diagnose hypertension, typically BP measurements obtained just before and after dialysis are used to diagnose and treat hypertension in hemodialysis patients (8,9). However, predialysis and postdialysis BP measurements are generally inaccurate estimates of ambulatory BP measurements (10). In the dialysis unit, BP measurements are obtained every 30 min during dialysis, primarily to ensure the hemodynamic stability of patients during treatment. But the BP measurements so obtained are usually ignored when making a diagnosis of hypertension. The utility of intradialytic BP measurements in diagnosing hypertension among hemodialysis patients therefore remains unknown.The purpose of our study was to evaluate the usefulness of intradialytic BP in diagnosing hypertension among hemodialysis patients. We measured the utility of intradialytic BP by comparing the dialysis-to-dialysis reproducibility and comparing the bias, precision, and accuracy of intradialytic BP measurements to the reference standard of interdialytic ambulatory BP recordings. Finally, we constructed receiver-operating characteristic (ROC) curves to determine clinically useful cut-points and to assess the diagnostic performance of intradialytic BP recordings.     

Borrelia in Ethiopian ticks

Two regions (Jimma and Dire Dawa) in Ethiopia were investigated for the presence of soft ticks. Although no Ornithodoros spp. ticks were collected during this survey, published records of their existence in Ethiopia were found. An overwhelming infestation of Argas persicus was revealed in a village located adjacent to Dire Dawa. These ticks primarily were feeding on poultry, but were also biting humans. Furthermore, hard ticks were collected from livestock and companion animals in these regions.Collected ticks were assessed for Borrelia by real-time PCR followed by conventional PCR and sequencing to identify species present. A. persicus ticks were found to carry B. anserina in 3 of 40 (7.5%) A. persicus tick pools, whilst hard tick pools yielded 2 of 16 (12.5%) positive for B. theileri. Collectively, these borrelial species and their tick vectors are likely to have an important economic impact of particular relevance to subsistence farmers in Ethiopia.     

Heteronormativity and ‘troubled’ masculinities among men who have sex with men in Addis Ababa

In most societies, heterosexuality is the dominant way of expressing sexuality and masculinity and those men outside of it are stigmatised and discriminated against. This paper explores the sexual lives of men who have sex with men and the personal and social conflicts that arise as they attempt to both live up to societal expectations and manage their sexual desires. It critically explores how an overriding heteronormativity structures and influences men's perception and understanding of sexuality and masculinity/femininity. The paper draws on data from 24 in-depth/life history interviews, one focus group discussion and ethnographic observation conducted between July 2006 and June 2007. The study reveals that powerful and dominating beliefs about heteronormativity and masculinity result in men who have sex with men dealing with a number of issues of personal conflict and contradiction resulting in uncertainty, resentment, ambivalence, worry and discomfort. Heteronormativity or the expectations of parents, community and society at large is far more influential on the sexuality of men who have sex with men than their own individual desires and needs. The paper concludes that there is little room for individuality for Ethiopian men who have sex with men with their sexual bodies ‘belonging’ to parents, families and to society at large.     

Pattern and Outcome of Traumatic Brain Injury,Addis Ababa,Ethiopia: A Cross-sectional Hospital-based Study

BackgroundTraumatic brain injury (TBI) is the leading cause of death and disability in young adults in the world. This study assessed clinical characteristics and in-hospital outcomes among traumatic brain injury patients presenting to Addis Ababa Burn, Emergency, and Trauma hospital.MethodsA cross-sectional hospital-based survey was conducted at AaBET hospital from January 01/2020 to April 30/2020. Data were collected using structured questionnaires from the trauma registry and patient chart. The collected data were analyzed using statistical software SPSS v 25.0.ResultsAmong the 304 traumatic brain injury patients, 75% were males with a mean age of 30.4 + 15.7, and 59.2% came from the Oromia region. Road traffic injury was responsible for 45% of the cases, of which pedestrian struck accounts for 52.2% of the cases. Only 50 (16.4%) patients arrived below 02 hours. 201 (66.1%) patients had mild traumatic brain injury the rest had moderate to severe traumatic brain injury. Skullbone fracture (linear, DSF, & BSF) was the most common (n=157, 63.1%) followed by intracerebral lesions (DAI, brain contusion, & ICH) (n=140, 56.5%). Forty-three (14.1%) patients were intubated. 45(14.8%) cases had a neurosurgical intervention. The mortality rate of severe, moderate, & mild TBI were 25%, 8.0% & 2.0% respectively with an overall mortality of 5.6%.ConclusionThis study showed road traffic injury was the commonest cause of traumatic brain injury which affected young age groups. There was a delayed presentation to AaBET hospital Emergency. The mortality rate was lower than other Ethiopian hospital studies.     

Costs of illness and coping strategies in a coffee-growing rural district of Ethiopia

The paper describes a cross-sectional household survey conducted in randomly-selected villages in rural Ethiopia to assess strategies of households for coping with financial and time costs of illness. Results of the survey showed that the average monthly household health expenditure was 32.87 Birr (about 4.1 US dollars [1 US dollar = 8 Birr at the time of study]). In addition, the average time lost due to illness was 9.23 days for the sick and 7.38 days for their caretakers. Monetary price was a significant (p<0.05) deterrent from visiting health facilities among households with no land or house, the divorced or widowed, and those with annual income less than 500 Birr (62.5 US dollars). The main strategies to cope with the financial costs of illness were waiver privileges, selling household assets, and using savings. Division of labour among household members was used for compensating for the loss of working time due to sickness. The findings of the study indicate that financial and time costs of illness seem to significantly contribute to the impoverishment of rural households.
