BACKGROUND Human cystic echinococcosis (hydatidosis) continues to be an essential cause of morbidity and mortality in many parts of the world. METHODS We studied hydatid cyst pattern in hospitalized adult patients from 2003 to 2012 in Mashhad and Neyshabour, northeast of Iran. RESULTS Overall, 1342 patients, 711 females (53%) and 631 males (47%) diagnosed as infected with hydatid cyst were ...

INTRODUCTION The aim of this study was to investigate the relative influence of genetic and environmental factors on children's leisure time exercise behavior through the classic twin design. METHODS Data were taken from The Netherlands Twin Register. The twins were 7 (n = 3966 subjects), 10 (n = 3562), and 12-yr-olds (n = 8687), with longitudinal data for 27% of the sample. Parents were aske...

Search results for nucleon decays p→e^{+}X, p→μ^{+}X, n→νγ (where X is an invisible, massless particle) as well as dinucleon decays np→e^{+}ν, np→μ^{+}ν, and np→τ^{+}ν in the Super-Kamiokande experiment are presented. Using single-ring data from an exposure of  273.4  kton·yr, a search for these decays yields a result consistent with no signal. Accordingly, lower limits on the partial lifetimes...

The objective of this study was to assess the influence of age on the efficacy and toxicity of methotrexate in rheumatoid arthritis. Four hundred and sixty-nine patients were separated according to the age of onset of methotrexate treatment; before 65 yr (group 1, n = 416) and after 65 yr (group 2, n = 53). No difference was found in the evolution of clinical and biological parameters between t...

purpose: to evaluate the role of anxiety in idiopathic acute anterior uveitis. methods: in this case-control study, three groups including 30 patients with uveitis, 30 patients with conjunctivitis, and 30 healthy controls were enrolled for estimating the anxiety level by employing zung anxiety assessment and a structured clinical interview. t test and chi square test were used for statistical a...

Sarcoidosis may be affected by sex, race, and age. A Case Control Etiologic Study of Sarcoidosis (ACCESS) enrolled 736 patients with sarcoidosis within 6 mo of diagnosis from 10 clinical centers in the United States. Using the ACCESS sarcoidosis assessment system, we determined organ involvement for the whole group and for subgroups differentiated by sex, race, and age (less than 40 yr or 40 yr...

For determination of the incidence of renal events in autosomal dominant polycystic kidney disease (ADPKD) all patients who had ADPKD and attended nephrology/urology clinics in Newfoundland in 1981 were identified, and members of 18 families who were at 50% risk for inheriting ADPKD were followed prospectively for 22 yr, including research clinics at 6-yr intervals. Time to hypertension treatme...

Sometimes, the clinical findings and the results of the gonadotropin-releasing hormone (GnRH) stimulation test are inconsistent in girls with early breast development and bone age advancement. We aimed to investigate the factors predicting positive results of the GnRH stimulation test in girls with suspected central precocious puberty (CPP). We reviewed the records of 574 girls who developed br...
