Background The Michigan Hand Questionnaire (MHQ) is widely used to assess the hand/wrist conditions. We translated the original version into Thai (Thai MHQ) and evaluated its psychometric properties. Methods After receiving permission, the original MHQ was translated and cross-culturally adapted to Thai following standard guidelines. Two hundred and seventeen patients who had hand/wrist injuries or disorders were included in the study. Internal consistency was evaluated using Cronbach’s alpha. Test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Spearman’s rank correlation among the subscales of Thai MHQ, Thai DASH and Thai EQ-5D-5L and also confirmatory factor analysis (CFA) were used to explore construct validity. The standardized response mean (SRM) was used to evaluate the responsiveness of the Thai MHQ. Results All subscales showed an acceptable Cronbach’s alpha (0.79–0.98). The test-retest reliability of each subscale was good (ICC = 0.83–0.95). In related dimensions, strong correlation was demonstrated between the Activities of daily living subscale of the Thai MHQ and the Common activities subscale in the Thai DASH (r = 0.77, P < 0.0001). For unrelated dimensions, a weak correlation was found between the Aesthetics subscale in the Thai MHQ and the Mobility subscale in the Thai EQ-5D-5L (r = − 0.13, P = 0.05). The Thai MHQ had strong correlation with Thai DASH (r = − 0.79, P < 0.0001) and Thai EQ-5D-5L (r = 0.63, P < 0.0001). CFA showed that the 6-factor model demonstrated an acceptable fit to the data. The SRM of the Thai MHQ was 0.78, indicating relatively large responsiveness. The MIC of Thai MHQ using distribution methods (SEM) was 5.2. Conclusions The Thai MHQ provides adequate internal consistency in all subscales as well as good construct validity and reliability for Thai patients and a relatively large standardized response mean at 2 months after treatment.

Acromion is a major associated structure of subacromial impingement syndrome, one of the most common diagnoses in chronic shoulder pain worldwide. The aims of this study are to study morphometry of acromion and to find risk group using acromial morphometry. Total samples were 392 scapulae. The samples were of both sexes, ranging from the age of 31 to 90. Acromion type and osteophytes were observed. Acromial parameters were measured. The relationships were analyzed among acromion type, acromial osteophyte, acromial parameters, age group, sex and side. Curved acromion had the highest prevalence in all age groups. Hooked acromion had the second highest prevalence since the age of 41. Hooked acromion prevalence was higher in male than in female. The highest prevalence of acromial osteophytes was on anteroinferior surface in all age group. The prevalence of acromial osteophytes on anteroinferior surface and acromial facet increased with age. In addition, acromion type was associated with only osteophytes on anteroinferior surface of acromion. Anterior one-third acromial thickness in the age of 31 to 50 was different from those of 51 to 90. There are differences between all parameters and sexes, but not side. General population with age above 50 and concerned male group with age above 40 who have chronic shoulder pain should be investigated for subacromial impingement syndrome. Surgical treatment is recommended because hooked acromion and osteophytes are mostly the root of problem.

Background In recent decades, cannabis has been widely used around the world for medical and recreational purposes, both legally and illegally. Aside from its therapeutic benefits, cannabis exhibits many adverse effects. Psychosis is one of the potentially harmful effects of cannabis. Case presentation A 23-year-old Thai man, who reported cannabis use for 2 years and discontinued for 3 months, restarted smoking two bongs (2 g equivalence) of cannabis. Two hours later, he had a penile erection, felt a severe persistent sharp pain in his penis, and reported that his glans looked distorted. Intending to eradicate the pain, he decided to trim the penile skin several times and completely amputated his penis himself using scissors. Cannabis-induced psychosis was diagnosed because symptoms began after cannabis use, without evidence of other substance abuse. To confirm the cannabis exposure, his urine immunoassay was positive for delta-9-tetrahydrocannabinol (Δ9-THC). The distal penis was deemed too dirty and fragile for reconstruction. Bleeding was controlled, penile stump irrigated and debrided, and scrotal urethrostomy was performed by a urologist. After admission and cannabis discontinuation, his delusion and hallucination subsided. Conclusions Cannabis-induced psychosis is an adverse effect of cannabis, which may lead to impaired judgement unexpected self-harm. A multidisciplinary team approach, including a primary care physician, an emergency physician, a urologist, and a psychiatrist, is essential when dealing with a patient with cannabis-induced psychosis and a urogenital injury.
