Prevalence of the Different Types of Palmar Creases Among Medical and Dental Students in Addis Ababa, Ethiopia
No full textBACKGROUND: Studies have suggested that identification of aberrant palmar creases may give clues for an early and noninvasive method of diagnosis of certain disease conditions. Toward this purpose, awareness of the normal variants of palmar creases must be first recognized. Accordingly, this study aimed to investigate the patterns of palmar creases in healthy Ethiopian population among Medical and Dental Students in Addis Ababa.SUBJECTS AND METHODS: Right and left palm pictures from 318 (177 females and 141 males) participants were taken using a mobile camera, and evaluated qualitatively. Observations were analyzed by Fisher's exact test, and significance levels for comparisons were set at p<0.05.RESULTS: Aberrant creases were observed in 13.8% of the palms. Simian crease was the most common among the aberrant crease types, followed by Suwon and Sydney. Palmar creases with two and three points of origin were significantly more common, respectively, in males and the females. Minor variants as accessory to the radial longitudinal crease and middle longitudinal crease were also observed.CONCLUSION: This study suggests that aberrant crease types at the observed frequencies may not be indicative of known disease conditions as they occurred in apparently healthy Ethiopians. However, the results of this study, besides revealing the patterns of palmar creases among Ethiopians, could give a baseline for studies aimed at diagnosis of disease conditions based on palmar crease configurations. Further qualitative and quantitative studies of palmar creases in wider populations with various conditions, including ethno-geographic factors, are recommended
Precancerous lesions of the cervix and its determinants among Ethiopian women: Systematic review and meta-analysis.
No full textIntroductionPrecancerous lesions of the cervix are changes in cervical cells that make them more likely to develop into cancer. Understanding the prevalence and determinants of the precancerous lesions of the cervix among women helps to take an action like vaccination programs, improving screening coverage, and close management and follow-up which could decrease the morbidity and mortality caused by cervical cancer.Materials and methodsThe international databases, PubMed/MEDLINE, Web of Science, EMBASE, CINAHL, Google Scholar, Science Direct and Cochrane Library and unpublished reports were systematically searched. Two authors independently extracted all necessary data using a standardized data extraction format. STATA 14 statistical software was employed to analyse the data. The Cochrane Q test statistics and I2 tests were used to assess the heterogeneity between the studies. A random-effect model was computed to estimate the pooled prevalence of precancerous lesions of the cervix in Ethiopia. Determinants of the precancerous lesion of cervix (early initiation of sexual intercourse, multiple sexual partners, and history of sexually transmitted infection) were analysed.ResultsThirteen studies fulfilled the inclusion criteria and included in the meta-analysis. The I2 test result showed high heterogeneity (I2, 93.2%, p = ConclusionThe pooled prevalence of the precancerous lesions of the cervix among Ethiopian women was 9.43%. It was associated with having multiple sexual partners and a history of sexually transmitted infections

No full textBackground: Greulich and Pyle standards are the most widely used age estimation standards all over the world. The applicability of the Greulich and Pyle standards to populations which differ from their reference population is often questioned. This study aimed to assess the reliability of Greulich and Pyle (GP) method for determination of age of children at Debre Markos Referral Hospital, East Gojjam Zone, Ethiopia. Subjects and Methods: Hospital based cross sectional study design was applied to children who came to Debre Markos Referral Hospital from May to October 2015 and fulfilled the inclusion criteria of the study. The data was analyzed using SPSS version 20 and medcalc version 15 softwares. Significance was set at α = 0.05. Results: A total of 108 radiographs were analyzed. Chronological age in most of the children was under estimated. The mean under-estimation was 11.8 months in the female sample and 8.7 months in the male sample. Greulich and Pyle method became inapplicable for the sample at 16 years for females and 16.5 years for males and later. Delay in skeletal maturation was observed in both sexes, but the females in the sample matured earlier than the males. Conclusion: The findings of this study suggest against the applicability of GP atlas which were not directly applicable to an East Gojjam Zone population. Large scale studies should be planned and nationwide guideline, and atlas which can easily be used throughout the country should be developed. Keywords: Chronological age, bone age, Greulich and Pyl
