Achenbach and Edelbrock teacher and parent checklists were used to develop a practical procedure to assist educators in determining if a boy with behavioral/emotional dysfunction in elementary school requires mental health referral or SED evaluation. SED, psychiatric outpatient, and general population Caucasian boys ages 6 to 11 years were compared. Appropriately, scores for the SED and the outpatient groups were pathological and significantly greater than scores for the general population group on both checklists, while SED scores were significantly higher than outpatient scores on the teacher checklist. Logistic regression analyses showed the Total Problem scales of both checklists to be the most efficient and economical scales for classification. Finally, probability tables were constructed to distinguish SED and outpatient boys from general population boys, and SED boys from outpatient boys.

Objectives: Obstructive sleep apnoea (OSA) may be more common in people with schizophrenia compared to the general population, but the relative prevalence is unknown. Here, we determine the relative prevalence of severe OSA in a cohort of men with schizophrenia compared to representative general population controls, and investigate the contribution of age and body mass index (BMI) to differences in prevalence. Methods: Rates of severe OSA (apnoea–hypopnoea index > 30) were compared between male patients with schizophrenia and controls from a representative general population study of OSA. Results: The prevalence of severe OSA was 25% in the schizophrenia group and 12.3% in the general population group. In subgroups matched by age, the relative risk of severe OSA was 2.9 ( p = 0.05) in the schizophrenia subjects, but when adjusted for age and BMI, the relative risk dropped to 1.7 and became non-significant ( p = 0.17). Conclusions: OSA is prevalent in men with schizophrenia. Obesity may be an important contributing factor to the increased rate of OSA.

Background: It has been suggested that limb circulation may be disturbed in patients with muscle cramps due to leg venous hypertension. The aim of this study was to examine the incidence and characteristics of muscle cramps from venous insufficiency. Patients and methods: The incidence and characteristics of muscle cramps, which were investigated by a questionnaire, were compared between 288 patients with incompetence of the long or short saphenous vein and 550 age-matched individuals from the general population. Results: The patient group showed a significantly higher incidence of muscle cramps in the last year than the general population group, 67% and 53%, respectively (p < 0.001). The incidence of calf cramps was significantly higher in the patient group than in the general population group, 91% and 75%, respectively (p < 0.001). Although most subjects reported symptoms occurring only at night, the incidence was significantly higher in the patient group than in the general population group, 78% and 52%, respectively (p < 0.001). There was no significant difference in the duration or severity of muscle cramps between the groups. The patient group showed a significantly higher incidence of more than 12 episodes per year than the general population group (p < 0.001). Conclusions: Muscle cramps in patients with varicose veins occur more frequently and more often at night and in the calf in comparison with those from the general population.

Abstract Objectives Patients with osteoarthritis and ankylosing spondylitis have lower cancer-related mortality than the general population. We examined risks of solid cancers at 16 sites in elderly patients with knee or hip osteoarthritis (KHOA) or ankylosing spondylitis. Methods In this population-based retrospective cohort study, we used US Medicare data from 1999 to 2010 to identify cohorts of persons with KHOA or ankylosing spondylitis, and a general population group without either condition, who were followed through 2015. We compared cancer incidence among groups, adjusted for age, sex, race, socioeconomic characteristics, geographic region, smoking and comorbidities. Results We studied 2 701 782 beneficiaries with KHOA, 13 044 beneficiaries with ankylosing spondylitis, and 10 859 304 beneficiaries in the general population group. Beneficiaries with KHOA had lower risks of cancer of the oropharynx, oesophagus, stomach, colon/rectum, hepatobiliary tract, pancreas, larynx, lung, and ovary than the general population. However, beneficiaries with KHOA had higher risks of melanoma, renal cell cancer, and cancer of the bladder, breast, uterus and prostate. Associations were similar in ankylosing spondylitis, with lower risks of cancer of the oesophagus, stomach, and lung, and higher risks of melanoma, renal cell cancer, and cancer of the renal pelvis/ureter, bladder, breast, and prostate. Conclusion Lower risks of highly prevalent cancers, including colorectal and lung cancer, may explain lower cancer-related mortality in patients with KHOA or ankylosing spondylitis. Similarities in cancer risks between KHOA and AS implicate a common risk factor, possibly chronic NSAID use.

Typhoid fever is one of the prevailing endemic diseases of Palestine. In 1925 and 1926 epidemic outbreaks of considerable magnitude occurred in various parts of the country (Kligler, 1927). As a part of a general programme of the study of the epidemiology of this disease, we have attempted to ascertain the incidence of typhoid carriers in a general population group. Owing to the large number of typhoid cases which occurred there in 1925 and 1926, Afule, a village of some 1200 inhabitants, was chosen as a desirable spot for such an investigation.

Out Of Pocket Costs

Medical out-of-pocket costs paid by patients can be problematic when it adversely affects access to care. Survey research involving patients with out-of-pocket expenses may have selection biases, so accurate estimates are unknown. During 2010–11, 419 participants from the QSkin Sun and Health Study (n=43794) had a confirmed diagnosis of either melanoma, prostate, breast, colorectal or lung cancer. These were matched to a general population group (n=421) and a group of high users of GP services (n=419). Medical fees charged and out-of-pocket medical expenses for Medicare services were analysed. Over 2 years, three-quarters of individuals with cancer paid up-front provider fees of up to A$20551 compared with A$10995 for the high GP user group and A$6394 for the general population group. Out-of-pocket expenses were significantly higher for those with cancer (mean A$3514) compared with the high GP-user group (mean A$1837) and general population group (A$1245). Highest expenses were for therapeutic procedures (mean A$2062). Older individuals, those with poor perceived health or private health insurance had the highest costs. Regardless of private insurance status, patients with one of the main five cancers pay significantly higher out-of-pocket costs for health care compared with those without cancer.

Teacher’S Report Form

Boys aged 6 to 11 years recommended for SED placement were investigated with the Teacher's Report Form and the parent Child Behavior Checklist to determine their severity of dysfunction in both school and home environments. Their scores were also compared with the scores of outpatient and inpatient groups of boys with psychiatric disorders, and a general population sample of boys, all groups from the same geographic area. The teacher ratings for the SED boys were generally mean T scores of 68 or greater, ranked highest among the four groups, and were significantly higher than the outpatient and general population groups. Their parents' ratings were generally mean T scores of 65 or greater, were second in severity to the ratings for the inpatient boys, and were significantly greater than the general population group. Thus, serious degrees of dysfunction were found for these SED boys in both environments.
