Cultural Adaptation and Validation of an Arabic Version of the Modified Harris Hip Score.

Context Although the Modified Harris Hip Score (MHHS) is used worldwide, it has not been translated into Arabic or validated for use among Arabic populations. Aim This study aimed to translate the MHHS into Arabic and to culturally adapt and validate the Arabic version. Design A cross-sectional study of the MHHS was performed. Methods The MHHS was translated into Arabic using forward-backward translation. A total of 183 adults who could speak and read Arabic completed the questionnaire. Cronbach's alpha was used to assess internal consistency with respect to the total and subscale scores. Pearson's correlation coefficient was used to evaluate associations between the total scores, and the subscales and intersubscales. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC). The Kaiser-Meyer-Olkin value was determined before principal component analysis to evaluate the validity of the construct and the reliability of the data, and correlations among the score items were estimated. Results All the participants understood the questions. The ICCs for the total score, function subscale, and pain subscale were 0.936, 0.936 and 0.893, respectively. Cronbach's alpha was acceptable for the total score (0.792) and good for the function subscale (0.895). The total score and the function (r = 0.976; p < 0.001) and pain (r = 0.971; p < 0.001) subscales correlated significantly. Regarding score validity, all the MHHS items correlated with the total score (p < 0.001). Conclusions The reliability and validity of the Arabic version of the MHHS was demonstrated. The MHHS can be used to assess hip pathology among adults in Saudi Arabia.

Characteristics and recurrence of pterygium in Saudi Arabia: a single center study with a long follow-up.

BACKGROUND: This study described the clinical features of patients with pterygium and analyzed the recurrence rate of conjunctival autografting alone, conjunctival autografting combined with intraoperative mitomycin C, and amniotic membrane grafting. METHODS: A retrospective cohort study of primary pterygium was conducted between January 2017 and February 2020. Factors associated with pterygium severity and recurrence were analyzed by univariate analysis and logistic regression models. RESULTS: The study included 292 patients with an average age of 53.3 ± 14.1 years, while the number of operated cases was 94. Pterygia involving the cornea were observed in 55 % of the cases. The overall rate of recurrence for the three procedures was 17 %. The average time of recurrence was 14.2 ± 11.9 months, with 37 % of the recurrences occurring after the first year. The only factor associated with a significant risk of recurrence was dry eye disease in both univariate (p = 0.021) and multivariate analysis (p = 0.026). The recurrence rates following conjunctival autografting with and without mitomycin C were 15.6 and 15.8 %, respectively. The recurrence rate following the amniotic membrane graft was  twofold (OR= 2.02)  (27 %) that following the conjunctival autograft (15.8 %). CONCLUSIONS: The only factor associated with the recurrence of pterygium was dry eye disease. More than one-third of recurrences developed after the first year, which stresses the importance of a long follow-up. The recurrence rate in our study following conjunctival graft was slightly higher compared to the literature mainly due to differences in study areas, populations, and follow-up periods.

Impact of critical care medicine publications from intensive care department at King Abdulaziz Medical City, Riyadh in the last two decades.

INTRODUCTION: The volume and quality of biomedical research publications from an institution are considered adequate indicators of the quality of medical care in that institute. King Abdulaziz Medical City (KAMC), Riyadh, Kingdom of Saudi Arabia (KSA), is one of the oldest and most distinguished medical centers in the country. METHODS: In this study, we analyzed the number of publications from the Critical Care Unit of the hospital in the past two decades, from 1996 to 2016. The research publications were evaluated on various parameters. Moreover, the impact of their study on global medicine was determined. RESULTS: Our results indicate a steady progression in the number of publications from the institute in the past two decades. An average of 17.3 papers was published each year during this time. Out of the 283 publications from KAMC included in this study, the majority of the publications were original articles, 61 were review articles, 66 were multicenter trial studies and 28 were randomized control trials. The citation profile of the publications was good indicating global impact of the studies. CONCLUSION: The global impact of research as evaluated through published manuscripts in KAMC is overall good. This was deduced from both the increase in the number of publications each year and also the quality of papers as evidenced by the citation index of the papers published between 1996 and 2016.
