The Prevalence of Scoliosis among Adolescent Chest Radiographs Obtained at Tikur Anbessa Specialized Hospital in 2019.

Background: Scoliosis is an abnormal side-to-side spinal curve of greater than or equal to 100 Cobb angle. It is the most common spinal deformity in children and adolescents. Epidemiological evidence about scoliosis is scarce in Africa, including Ethiopia. This study was aimed at determining the prevalence of scoliosis among adolescents and analysing its association with age and sex using plain chest radiographs obtained for non-spinal reasons in Tikur Anbessa Specialized Hospital. Method: All non-tilted, non-rotated, and non-poorly penetrated digital plain chest radiographs of adolescents aged 10 to 19 years obtained at Tikur Anbessa Specialized Hospital between January 1 and December 31, 2019, were measured for the coronal Cobb angle. The data were cleaned, coded, and entered into SPSS version 26 for analysis. Chi-square, and linear regression, and logistic regression analyses were also carried out to evaluate the effect of sex and age on scoliosis. Results: The Cobb angles of 1,369 posteroanterior chest radiographs of adolescents were measured. Thirty (2.2%, 95% CI: 1.4%, 3.0%) of these were found to have scoliosis. The mean coronal Cobb angle was 2.270±6.320. There was no statistically significant difference between the prevalence of scoliosis in boys (2.21%) and girls (2.17%) (X2=0.003, P=0.954). Likewise, age did not show any statistically significant difference in the prevalence of scoliosis (X2=2.655, P=0.265). Conclusion: This study revealed that incidental finding of adolescent scoliosis in plain chest radiographs is common. Further study using whole spine radiography should be carried out to determine the true general population prevalence of scoliosis in Ethiopia.

Effects of Nutritional Status on Neurodevelopment of Children Aged Under Five Years in East Gojjam, Northwest Ethiopia, 2021: A Community-Based Study.

Introduction: Scientific evidence regarding relationships between developmental status and nutritional status of children aged under five years old is scarce, particularly in Africa. Thus, the objective of the present study is to evaluate the relationships between nutritional status and developmental status among children aged under five in Gojjam, Ethiopia. Methods: A cross-sectional study was conducted on 390 child-mother pairs from December 1-30 2021. Developmental status, nutritional status and related data were collected using age and stage questionnaire 3rd edition (ASQ-3) and measurements of body dimensions and other physical characteristics. Body dimensions data was obtained by measurement of height and weight of children aged under five years. Logistic regression analysis was executed to identify factors related with poor child developmental status. Adjusted odds ratio (AOR) and 95% CI was estimated to reveal the strength of association and statistical significance were declared at p-value less than 5%. Results: The overall prevalence of developmental delay in the current study among under five years children was 22.6%. Moreover, in this study the prevalence of stunting, wasting and being underweight was 36.3%, 14.2% and 20.3%, respectively. Developmental delay among under-five children was significantly associated with experiencing repeated diseases during pregnancy (AOR: 2.43; 95% CI:1.38, 4.28), short birth interval (AOR: 2.78; 95% CI :1.52, 5.09), stunting (AOR: 2.61;95% CI: 1.41, 4.84), wasting (AOR: 3.68;95% CI: 1.61, 8.37) and being underweight (COR: 3.28;95% CI: 1.91, 5.63). Conclusion: The overall developmental delay prevalence among under-five children in the present study was 22.6%. The prevalence of stunting, wasting and being underweight was 36.3%, 14.2% and 20.3%, respectively. Maternal diseases, birth interval and nutritional status of children aged under five years were among the factors which revealed statistically significant associations with developmental delay of under-five children. We recommend the concerned body to work on improving maternal health status during pregnancy, to enable mothers to adequately space subsequent births, and to work on improving the nutritional status of women and children in the current study area in order to improve the developmental status of children aged under five.

Prevalence of neural tube defects at Debre Berhan Referral Hospital, North Shewa, Ethiopia. A hospital based retrospective cross-section study.

BACKGROUND: Neural tube defect (NTD) is a structural defect of the central nervous system of the developing embryo during the first month of developmental process. Most congenital malformations are potentially preventable cause of perinatal morbidity and mortality. Worldwide, around 10% of infant mortalities are due to nervous system defects. In Ethiopia there are limited published data regarding the prevalence and established preventive strategy of NTDs. The purpose of this study was to assess the prevalence of NTDs among pregnancy outcomes in Debre Berhan Referral Hospital (DBRH), Ethiopia. METHODS: Hospital based retrospective cross sectional, descriptive study was conducted on registration of all pregnancy outcomes from August 30, 2017 to August 30, 2019 at DBRH, Ethiopia. The collected data were checked for completeness and consistencies, and cleaned, coded and entered using Epi data version 4.2 and exported to Statistical Package for Social Sciences (SPSS) software version 20 for analysis. Variables were interpreted per 1000 pregnancies and those variables having p<0.05 was considered as statistically significant. RESULTS: The total prevalence of NTDs was 10.9 (95% CI 8.9 to 13.3) per 1000 pregnancies and the prevalence of each NTD type was anencephaly 5.6 (95% CI 4.2 to 7.4) per 1000 pregnancies, spina bifida 3.5 (95% CI 2.4 to 4.9) per 1000 pregnancies, encephalocele 1.1 (95% CI 0.6 to 2.0) per 1000 pregnancies, and both spina bifida and anencephaly 0.7(95% CI 0.3 to 1.4) per 1000 pregnancies. Among livebirths, aborted, stillbirths and medically terminated pregnancies (n = 8862), there were 50 anencephaly cases, 31 spina bifida cases, 10 encephalocele cases, and 6 cases affected by both spina bifida and anencephaly. CONCLUSION: The prevalence of NTDs in this study was among the highest globally reported. The total prevalence was 10.9 per 1000 pregnancies. Increased periconceptional folic acid use, counseling for women with certain medical illnesses at higher risk for NTDs, and early maternal screening for genetic factors are possible approaches to reduce in NTDs in the population.

Placental and Umbilical Cord Indices and Their Association with Fetal Distress in Hadiya Zone Public Hospitals, Southern Ethiopia: A Cross-Sectional Study.

BACKGROUND: The placenta and umbilical cord have been considered as significant contributors to the perinatal outcome and have contributed to some degree to neonatal mortality. The placenta has a very crucial role in normal fetal development. After about four weeks of gestation, the only link of the fetus to the placenta is the umbilical cord. Very little is known about placental and umbilical indices in Ethiopia. This study was aimed to determine placental and umbilical cord indices and their association with fetal distress in Hadiya zone public hospitals, southern Ethiopia. METHODS: This study included 249 placentae with the attached umbilical cord from normal singleton live birth with known gestational age. Bivariable and multivariable logistic regression was used, and variables with p < 0.25 in the bivariable analysis were entered into a multivariable logistic regression to identify the independent factors for the outcome variable. Odds ratios with 95% confidence were computed, and statistical significance was declared at p-value <0.05. RESULTS: Three-fourth (75.9%) of diameter of studied placenta was in normal range and 18.1%, 6.0% below and above normal range, respectively. About one-third (32.9%) of umbilical cords were short, 61.8% normal, and 5.2% long. Newborns with thin placenta [AOR = 3.43; 95% CI: 1.25, 9.40], short cord length [AOR = 3.43; 95% CI: 1.66, 7.09] and long cord length [AOR = 7.55; 95% CI: 2.07, 27.53] were significantly associated with fetal distress. CONCLUSION: In this study, deviation of umbilical cord length from the normal range and placental thickness were significantly associated with fetal distress. In addition, fetal distress was also associated with gestation age and sex of the newborn.

Evaluation of Antihyperglycemic Effect of Extract of Moringa stenopetala (Baker f.) Aqueous Leaves on Alloxan-Induced Diabetic Rats.

BACKGROUND: Diabetes is a serious metabolic disorder with complications that result in significant morbidity and mortality. Current drugs used for diabetes therapy are not free from side effects and do not restore normal glucose homeostasis. Therefore, the purpose of this study is to evaluate the antidiabetic effect of Moringa stenopetala (Baker f.) aqueous leaves extract. METHODS: Thirty rats of weight 90-150 gram were distributed to five groups (n= 6). Then labelled as diabetic control (DC), normal control (NC), extract treated (MS 250 and 500mg/kg), and glibenclamide treated (GL 5mg/kg). The experimental rats were induced by intra-peritoneal injection of Alloxan monohydrate at a dose of 180 mg/kg after dissolving in normal saline. Clinical biochemistry such as AST, ALT, ALP, urea, creatinine, and cholesterol, blood glucose level, histopathological and preliminary phytochemical screening were evaluated. RESULTS: Phytochemical tests revealed the presence of different secondary metabolites. Alkaloid, flavonoid, tannin, saponin, phytosteroids, phenols and terpenoids. Moringa stenopetala (Baker f.) leaves aqueous extract (250 and 500mg/kg) improved the body weight of rats, showed remarkable reduction in blood glucose concentration (P<0.05), and significantly decreased serum urea, creatinine, ALT, AST and ALP (P < 0.05). Levels of serum cholesterol remained unaltered in the experimental groups when compared with diabetic control. Histopathology of non-treated rats showed deterioration of insulin producing pancreas cells; nevertheless, ß-cells restoration was observed due to administration of Moringa stenopetala (Baker f.) aqueous leaves extract. CONCLUSION: It is possible to conclude that oral administration of Moringa stenopetala (Baker f.) aqueous leaf extracts (250mg/kg and 500mg/kg) for 28 days showed beneficial effects on antihyperglycemia, improved body weight and Alloxan damaged pancreatic ß-cells, and restored biochemical changes.

Estimation of Stature from Arm Span, Arm Length and Tibial Length among Adolescents of Aged 15-18 in Addis Ababa, Ethiopia.

BACKGROUND: Knowing the relationship between stature and different anatomical anthropometric parameters help forensic scientists, anatomists and clinicians to estimate standing height from mutilated remains of body parts in clinical practices and forensic investigations. It is a necessity when measuring height is unenviable due to certain medical conditions and in field studies. This study aims to estimate stature from arm span, arm length and tibial length among adolescents of age 15-18 in Ethiopia. METHODS: A school based cross-sectional study was carried out among 416 high school students in Addis Ababa, Ethiopia from May to June 2019. Stratified multi-stage sampling techniques were used to select the study participants. Anthropometric measurement including weight, height, arm span, arm length and tibial length was measured. Data entry was done by Epi-Data a version 4.4.3.1 and data analysis was carried out by Statistical Package for Social Sciences version 23. Regression models and multiplication factors were generated for estimation of height from anthropometric parameters. RESULT: From total participants 51.4% were females and 48.6% were males. The mean height of study participants was 164.36±8.89cm for males and 155.75±5.86cm for females. The correlation coefficients(R) of anatomical anthropometric measurements with height were: arm span (males R=0.843, females R=0.708), arm length (males R=0.806, females R=0.635), and tibial length (males R=0.738, females R=0.611). CONCLUSION: Stature predicted from arm span, arm length, and tibial length is a valid indicator of height. Arm span was appeared to be the best predictor of stature.

Attitude, Willingness, and Associated Factors in Organ Donation Among Health Professionals in Gondar, Northwest Ethiopia.

BACKGROUND: Organ transplantation is considered one of the greatest advances of modern science, and it has given many patients a renewed lease on life. The demand for organs far exceeds the supply. Health professionals are fundamental in the process of organ procurement. OBJECTIVE: To assess the attitude, willingness, and associated factors in organ donation among health professionals of Gondar, Ethiopia. METHODS: Our cross-sectional study was conducted among 382 randomly selected health professionals in Gondar using a self-administered questionnaire. Multivariable logistic regression analysis was applied to analyze the data. RESULTS: Among health professionals, 79.1% had favorable attitude toward organ donation and 74.6% were willing to donate their organs. After adjusting for covariates, the odds of having a favorable attitude about organ donation were 3.2 and 11.9 times higher in the professions of laboratory technologists and medical doctors, respectively. By keeping all other variables constant, attitude was found to be positively associated with awareness (adjusted odds ratio [aOR] 12.74, 95% confidence interval [CI] 3.71-43.8) and being a member of the Red Cross Association (aOR 5.24, 95% CI 1.46-18.96). Willingness was positively associated with awareness (aOR 6.25, 95% CI 2.0-19.53), a member of the Red Cross Association (aOR 5.09, 95% CI 1.5-17.22), a laboratory technologist (aOR 3.57, 95% CI 1.37-9.29), and a medical doctor (aOR 6.52, 95 % CI 1.93-22.01). CONCLUSIONS: The main findings indicated that the majority of health professionals in Gondar had a favorable attitude toward organ donation and were willing to donate their organs in times of need.

Neonatal and Maternal Complications of Placenta Praevia and Its Risk Factors in Tikur Anbessa Specialized and Gandhi Memorial Hospitals: Unmatched Case-Control Study.

BACKGROUND: Placenta praevia is a disorder that happens during pregnancy when the placenta is abnormally placed in the lower uterine segment, which at times covers the cervix. The incidence of placenta praevia is 3-5 per 1000 pregnancies worldwide and is still rising because of increasing caesarean section rates. OBJECTIVE: To assess and identify the risk factors and maternal and neonatal complications associated with placenta praevia. Method and Materials. Target populations for this study were all women diagnosed with placenta praevia transvaginally or transabdominally either during the second and third trimesters of pregnancy or intraoperatively in Tikur Anbessa Specialized and Gandhi Memorial Hospitals. The study design was unmatched case-control study. Data was carefully extracted from medical records, reviewed, and analyzed. Unconditional logistic regression analysis was performed using adjusted odds ratios (AOR) with 95% confidence intervals. RESULTS: Pregnancies complicated by placenta praevia were 303. Six neonatal deaths were recorded in this study. The magnitude of placenta praevia observed was 0.7%. Advanced maternal age (≥35) (AOR 6.3; 95% CI: 3.20, 12.51), multiparity (AOR 2.2; 95% CI: 1.46, 3.46), and previous history of caesarean section (AOR 2.7; 95% CI: 1.64, 4.58) had an increased odds of placenta praevia. Postpartum anemia (AOR 14.6; 95% CI: 6.48, 32.87) and blood transfusion 1-3 units (AOR 2.7; 95% CI: 1.10, 6.53) were major maternal complications associated with placenta praevia. Neonates born to women with placenta praevia were at increased risk of respiratory syndrome (AOR 4; 95% CI: 1.24, 13.85), IUGR (AOR 6.3; 95% CI: 1.79, 22.38), and preterm birth (AOR 8; 95% CI: 4.91, 12.90). CONCLUSION: Advanced maternal age, multiparity, and previous histories of caesarean section were significantly associated risk factors of placenta praevia. Adverse maternal outcomes associated with placenta praevia were postpartum anemia and the need for blood transfusion. Neonates born from placenta praevia women were also at risk of being born preterm, intrauterine growth restriction, and respiratory distress syndrome.

Histopathological Changes of Placenta Associated with Maternal Anaemia in Northeast Ethiopia: A Comparative Study.

BACKGROUND: Anaemia during pregnancy affects about half of all pregnant mothers in developing countries; it is the major causes of indirect maternal mortality. Anaemia can directly cause poor growth of fetus in utero due to inadequate oxygen flow to the placental tissue or it is indirect indicator of maternal nutritional deficiency. Mal-development of placenta is the leading cause of maternal and perinatal mortality and an important factor of fetal growth retardation. The aim of this study was to compare histopathological changes of placenta associated with maternal anaemia. METHODS: A comparative cross-sectional study was conducted from May-June, 2018 in Dessie Referral Hospital. A total of 66 placentas (33 anaemic and 33 non-anaemic) were collected after delivery. EPI data version 4.2.0 was used to enter the data while the data were analyzed by using SPSS version 22. Chi-square and one-way ANOVA were used to analyze the data. RESULTS: In pregnancies with maternal anaemia, 75.7% of anaemic placentas terminal villi vessels were increased in number, compared to 15.1% in non-anaemic (p=0.001). Placental calcification was 72.7% in anaemic groups compared to 54% in non-anaemic groups. However, it was insignificant (p=0.12). Intervillous space was wider in anaemic compared to non-anaemic groups (p<0.001). CONCLUSIONS: Chorionic villi capillaries were increased in number, and it was dilated in anaemic placenta, compared to non-anaemic. Intervillous space was significantly wider in anaemic placenta.

Prevalence and root causes of surgical site infection among women undergoing caesarean section in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Surgical site infection is a common complication in women undergoing Caesarean section and the second most common cause of maternal mortality in obstetrics. In Ethiopia, prevalence and root causes of surgical site infection post-Caesarean section are highly variable. This systematic review and meta-analysis estimate the overall prevalence of surgical site infection and its root causes among women undergoing Caesarean section in Ethiopia. METHOD: Systematic review and meta-analysis were conducted to assess the prevalence and root causes of surgical site infection in Ethiopia. The articles were searched from the databases such as Medline, Google Scholar and Science Direct. A total of 13 studies from different regions of Ethiopia reporting the prevalence and root causes of surgical site infection among women undergoing Caesarean section were included. A random effect meta-analysis model was computed to estimate the overall prevalence. In addition, the association between risk factor variables and surgical site infection related to Caesarean section were examined. RESULTS: Thirteen studies in Ethiopia showed that the overall prevalence of surgical site infection among women undergoing Caesarean section was 8.81% (95% CI: 6.34-11.28). Prolonged labor, prolonged rupture of membrane, presence of anemia, presence of chorioamnionitis, presence of meconium, vertical skin incision, greater than 2 cm thickness of subcutaneous tissue, and general anesthesia were significantly associated with surgical site infection post-Caesarean section. CONCLUSION: Prevalence of surgical site infection among women undergoing Caesarean section was relatively higher in Ethiopians compared with the report of center of disease control guideline. Prolonged labor, prolonged rupture of membrane, presence of anemia, chorioamnionitis, presence of meconium, vertical skin incision, greater than 2 cm thickness of subcutaneous tissue and/or general anesthesia were significantly associated with surgical site infection post-Caesarean section.

Acute and Subacute Toxicity of Methanol Extract of Syzygium guineense Leaves on the Histology of the Liver and Kidney and Biochemical Compositions of Blood in Rats.

Plant medicine is the oldest form of health care known to mankind. Syzygium guineense is one of the many species of Ethiopian medicinal plants which has a long history of use as remedies for various ailments such as dysentery, diarrhea, and hypertension. In many countries, herbal medicines and related products are introduced into the market without safety or toxicological evaluation. The aim of this study was to investigate the histopathological effect of 80% methanol extract of S. guineense on liver and kidney and blood parameters of rats. For acute toxicity study, rats were randomly divided into three groups (n=4). The control group received distilled water, while the experimental groups received a single dose of 2000 mg/kg and 5000 mg/kg 80% methanolic extract of S. guineense leaves per oral. For subacute toxicity study, the rats were randomly divided into three groups (n=6). The control group received distilled water, while the experimental groups received 500 mg/kg and 1500 mg/kg 80% methanol extract of S. guineense leaves orally for 28 days. At the end of the experiment, blood samples were collected for hematology and clinical chemistry evaluations. Gross pathology and histopathology of liver and kidneys were assessed. In the acute toxicity study, rats treated with 2000 mg/kg and 5000 mg/kg showed no toxicological signs observed on behavior, gross pathology, and body weight of rats. In the subacute toxicity study rats have showed no significant changes on behavior, gross pathology, body weight, and hematological and biochemical parameters, whereas both experimental groups had a lower blood glucose level compared with the control group (p < 0.05). There were no significant differences in the gross and histopathology of the liver and kidneys of experimental animals in extract exposed groups and their counterpart control. The 80% methanol extract of S. guineense does not produce adverse effects in rats after acute and subacute treatment. Before marketing a S. guineense leaf based remedy, subchronic and chronic toxicity evaluations need to be done.

Medical students' attitudinal changes towards cadaver dissection: a longitudinal study.

BACKGROUND: Recently, not only the medical school curriculum but also medical students' attitude towards cadaver-based learning of anatomy has changed. This investigation is therefore designed to analyse students' attitudes towards human cadaveric dissection before and after exposure to dissection. METHODS: A longitudinal survey was conducted among second year medical students in 2010 at the college of Medicine and Health Sciences, University of Gondar. All second year medical students (n=147) were included in the study where their attitudes were surveyed at three time points (one week prior to dissection session, a week after the initiation of dissection and eight weeks after the second survey). Three standardized and pretested questionnaires prepared in English were used to collected relevant data from the subjects. RESULTS: Out of the 147 students 85.7% were males. The subjects' age ranged between 18 and 23 with a mean and standard deviation of 19.5±1 years. This study has revealed that among majority of the students fear and nausea have decreased while their interest and excitement has increased on subsequent exposure to dissection (P<0.05). About 75% of students considered the dissection room as slightly or highly stressful. Smell of the cadaver and eye irritation as a result of the chemicals in it were the major aspects identified as making the dissecting room stressful. The result also showed that almost all (99%) considered cadaver dissection had very important educational value for anatomy learning. CONCLUSION: In the majority of the students fear and nausea had decreased while interest and excitement had increased on subsequent exposure to dissection. It also showed that chemical odour and eye irritations were the leading factors which create discomfort in the dissection room even though anatomical dissection by itself was not considered as a stressor. Thus, instructors are recommended to adequately prepare students mentally and emotionally before the commencement of the dissection session for an exciting and stress free anatomy learning though dissection.

Age at menarche and the menstrual pattern of secondary school adolescents in northwest Ethiopia.

BACKGROUND: Population studies on normal and dysfunctional characteristics of menstrual cycles are scarce in Ethiopia. In addition variability in menarcheal age and menstrual characteristics are common. Knowledge on this variability is necessary for patient education and to guide clinical evaluation. METHODS: A cross sectional study was conducted in two small towns called Dabat and Kola Diba, northwest Ethiopia between April and May 2007. Systematic sampling method was used to select 622 school girls from two secondary schools. A pretested questionnaire prepared in Amharic was used to gather data. Selected girls cooperated in answering the questionnaire in their classrooms under the supervision of the research team. Only 612 of the adolescent females were included in the final analysis, of which 305 were from Koladiba High School and 307 from Dabat. RESULTS: The age of the study subjects ranges between 14 and 19 with a mean (standard deviation) of 16.9 +/- 1 years. About 92.2% had attained menarche by the time the survey was conducted. The probit analysis of the status quo data yielded a median (CI) age at menarche of 14.8 (13.9-15.3) years. The average age at menarche by recall method was 15.8 +/- 1 years. The mean age at menarche was 0.3 years younger for urban females compared with rural ones (p < 0.001). A cycle length between 21 and 35 days was observed in 70.3% of the girls. The mean duration of flow was 4 +/- 1.3 days with a range of 2-7 days. The menstrual cycles were irregular in 42.8% of the subjects. The overall prevalence of dysmenorrhoea was 72% among these subjects. Premenstrual symptoms were present in 435 of the females (75.4%). The leading sources of menarcheal information to the adolescents were mothers (39.7%), followed by their friends (26.6%) and teachers (21.8%). CONCLUSION: In this study age of menarche was found to be delayed which is even higher than the findings indicated similar studies conducted in Ethiopia and other African countries. A significant number of students complain of abnormal menstrual cycle, dysmenorrhoea and premenstrual symptoms which call for appropriate counselling and management.
