Objectives:To create a food frequency questionnaire specifically designed to capture the dietary habits of Saudis and test its validity and reliability.Methods:This investigation is a longitudinal, test-retest study conducted in King Saud University, Riyadh, Kingdom of Saudi Arabia between December 2015 and March 2016. A list of 140 food items was included in the questionnaire where a closed-ended and open-ended approach was used. Regarding past year food frequency consumption and 24 hours dietary recall, body weight and height were collected. Internal consistency, test-retest reliability, completeness of the food list, and criterion validity were assessed.Results:One-hundred and thirty eight participants were interviewed to complete the 24 hours dietary recall and the constructed questionnaire. Approximately 85% of the food items reported in the dietary recall were covered in the food frequency questionnaire. The association of body mass index with meats (regression coefficients: 2.28) and dairy products consumption frequency was statistically significant (regression coefficients: 2.31). A high overall reproducibility rate of the questionnaire was detected (Pearsons’ correlation coefficient: 0.78 p<0.001).Conclusion:The developed questionnaire has a high reliability and reasonable validity, and suitable for use in nutritional epidemiological investigations in Saudi Arabia.

IntroductionProstatic cysts are uncommon and usually asymptomatic. In most cases, these cysts are found incidentally by imaging. In some cases, these cysts can be symptomatic and missed for years.Case reportWe report the case of a 36-year-old male patient presented with a 3-year history of weak urine stream, dysuria, frequency and urgency. Ultrasound, computed tomography and magnetic resonance imaging demonstrated a prostatic cyst measuring 1.5*1.2 cm occupying the bladder outlet and causing obstruction. Transverse incision of the cyst provided a satisfactory resolution of the patient’s complaint.ConclusionIncision of a symptomatic midline anterior prostatic cyst is a safe and effective management option with no potential risk of retrograde ejaculation.
