Trichotillomania Prevalence in an Arab Middle Eastern Population.

Aim: Trichotillomania (TTM) (hair-pulling disorder) is a relatively rare psychiatric condition. We are aware of no studies of this disorder in Arab Middle Eastern populations. We examine the prevalence and correlates of TTM in a community sample of individuals living in a large port city in western Saudi Arabia. Methods: An observational cross-sectional study of 511 adults aged 18 years or over living in Jeddah, Saudi Arabia, was conducted. After inquiring about demographic information and self-reported psychiatric disorders, the Massachusetts General Hospital Hair-Pulling Scale (MGH-HPS) was administered to assess symptoms of TMM. Results: A total of 9 of 511 participants (1.8%) scored above the cutoff for suspected TTM on the MGH-HPS, whereas 203 (39.7%) had a history of hair-pulling. Those with suspected TTM were more likely to be female (2.8% vs 0.4% in males, P = 0.047) and somewhat more likely to have a history of obsessive-compulsive disorder (OCD) (6.7% vs 1.5%, P = 0.093). Hair pulling was also more common in unmarried, not living with family, and unemployed. Among those with a history of hair-pulling, the most frequent locations were from the face (62.7%), head (55.7%), and legs (15.3%). Conclusions: While a history of hair-pulling is common in this community sample (40%), suspected TTM is much less prevalent (<2%), although not rare by any means. When present, the condition is more common in women and possibly in those with OCD.

Determining the Site of Upper Airway Narrowing in Snorers Using a Noninvasive Technique.

Background In this study, we aimed to determine the site of obstruction if surgical treatment is considered. Flexible nasopharyngoscopy is an invasive procedure currently used for the assessment of snoring and the level of obstruction. Here, we examine the role of Somnoscreen™ plus, a noninvasive cardiorespiratory polysomnographic device, in identifying the site of obstruction in patients presenting with snoring. Methodology This cross-sectional study was conducted in the Sleep Research Center at King Abdulaziz University Hospital. Polysomnography was conducted using Somnoscreen™ plus. All participants underwent flexible nasopharyngoscopy after polysomnography. Results Nasopharyngoscopy revealed that the most common site of obstruction was the nose and the soft palate (35.4%), followed by the soft palate alone (25%). Somnoscreen revealed that the site of obstruction was the nose and the soft palate in 18 (37.5%) patients and the nose alone in 16 (33.3%) patients. However, distal obstructions were not detected using Somnoscreen. The concordance of nasopharyngoscopy and Somnoscreen was 52.9%. However, it showed a discrepancy in identifying distal obstructions, which Somnoscreen™ plus failed to detect. Conclusions Somnoscreen appears to be sensitive for identifying proximal airway obstructions. The audio signal recordings can potentially be used as a tool to detect the site of airway obstruction in snoring; however, further studies are needed.
