To evaluate the diagnostic performance of waist to height ratio (WHtR) to screen for cardiovascular risk factors (CVRF) and metabolic syndrome (MetS) among Saudis. ⋯ Between June 2013 and August 2014, a cross-sectional study of 3,063 adult Saudis of both genders from King Khalid Hospital, Riyadh, Saudi Arabia was conducted. Using the "WHO STEPwise Surveillance-Instrument V2.1", which uses sequential steps including questionnaires and anthropometric and biochemical measurements of MetS and CVRF. Waist to height ratio validity in defining central obesity, MetS, and CVRF were tested using receiver operating characteristic curve (ROC), sensitivity, specificity, positive and negative predictive values, and accuracy. Using multivariate regression analyses for adjustment of confounders as age and gender were applied to compute adjusted odds ratios (aOR). Results: The diagnostic potential of WHtR was excellent for central obesity (area under the curve [AUC] = 0.98), and MetS (AUCs = 0.86); it was good for CVRF ≥2 (AUCs = 0.79) and was satisfactory for dyslipidemia (AUCs = 0.66). The sensitivities and negative predictive values exceeded 85% for diagnosing central obesity, diabetes, and hypertension. Adjusted odds ratios for age and gender showed that WHtR ≥0.50 significantly increased the risk of diabetes, hypertension, and ≥2 CVRF by almost 4-fold, and increased the risk of dyslipidemia by 2-fold. Conclusion: Waist height ratio showed a good diagnostic performance for CVRF and MetS among Saudis. Furthermore, WHtR ≥0.5 increased the risk of dyslipidemia, diabetes mellitus and hypertension.

To quantify the prevalence of primary dysmenorrhea, study its associated factors, and to assess its effect on the quality of life of female medical students. ⋯ Most female medical students suffer from primary dysmenorrhea, which adversely affects their quality of life and academic performance. Caffeine consumption demonstrated a significant association with primary dysmenorrhea. Periodical awareness programs to minimize the consequences of primary dysmenorrhea should be introduced.

To determine whether distance from a cochlear implant (CI) center can influences the ages of presentation and intervention for CI, which thus may influence CI outcomes in Saudi Arabia. ⋯ In Saudi Arabia, distance from CI center does not have a significant effect on age of presentation for CI intervention.

Chylopericardium is a rare clinical condition in which chyle leaks into the pericardial space owing to lymphatic system derangement. It can be idiopathic or occur secondarily to another clinical condition. Optimal management is accomplished through surgical intervention to impede leaks and drain fluid. ⋯ Since the patient was asymptomatic, she was treated conservatively with diet changes, pericardial drainage, and a pericardial window procedure. This type of case risks being misdiagnosed as tuberculosis, especially in countries where tuberculosis is endemic. In such cases, assessing pericardial fluid for chyle is crucial.
