Sexually transmitted infections in male prison inmates. Prevalence, level of knowledge and risky behaviours.

Data on the prevalence of sexually transmitted infections (STIs) and risk factors among incarcerated people are few and data about STIs awareness among inmates are even lacking. This study aimed to assess prevalence of STIs, risky behaviours and STIs level of knowledge in male inmates of the Casa Circondariale-Genova Marassi, the main penitentiary in Genoa, Italy. Between January and June 2019, 662 inmate medical records were retrospectively examined to obtain clinical and laboratory data about STIs. To investigate the inmate level of knowledge of STIs and their risky behaviours, 111consenting participants answered, anonymously, a written questionnaire. One hundred and twenty-two patients had at least one infectious disease when entered the prison: HIV (1.8%), HBV (2.7%), HCV (12.5%) and syphilis (1.3%). When asked to select from a list of diseases which ones they thought to be sexually transmitted, only 12% of the inmates answered correctly; most of them ignored which body fluids are at risk for HIV transmission, which STIs can induce tumors and if any vaccination exists to prevent STIs. Substance abuse was common among inmates that frequently exchanged needles for injecting drugs. To reduce the STIs incidence, it is necessary to target high-risk populations: everyone entering a prison should be offered a systematic screening of all STIs, including those currently neglected. Since STIs knowledge among inmates is poor and risky behaviours are diffuse, informative interventions in prison may provide an opportunity to educate such a high-risk population.

Prevalence of diffuse idiopathic skeletal hyperostosis among elderly subjects referred for radiological investigation in tertiary hospital at Oman / 대한해부학회지

Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by calcification of different entheseal sites including the anterior longitudinal ligament of the spine. There is no documented information about DISH in Oman. This study determined the prevalence of DISH and associated factors among elderly subjects in a national tertiary care referral hospital in Oman. This retrospective study reviewed chest X-rays of all patients aged more than 50 years, referred to the radiology department of Sultan Qaboos University Hospital in the year 2016, based on the Resnick's criteria. The prevalence was expressed as proportions across age groups and sex. Chi-square test and logistic regression analysis was done to determine the association of the age and sex with DISH. A total of 1305 chest X-rays of patients were reviewed. The overall prevalence of DISH was 10%, with male to female ratio of 1.56:1. The odds ratio for males and increasing age were 1.63 (95% confidence interval [CI], 1.12–2.3; P<0.05) and 1.34 (95% CI, 1.14–1.58; P<0.001) respectively. The prevalence increased with age to maximum of 13% in the age group of ≤80. The pre-stage DISH prevalence was 9.3% and more frequently observed among males. Prevalence of DISH in the national tertiary care referral center in Oman is lower than in Jewish population, almost similar to Japanese, but higher than in Koreans. DISH prevalence is positively associated with age and sex. It is necessary to take appropriate precautionary measures to target the ageing population in Oman, especially elderly males.
