This is a retrospective study on clinical course and treatment response of patients with thyroid hot nodule, referred to nuclear medicine department of Shariati Hospital from 1360 to 1377. From the total 58 patients with average age of 43 yr and incidence peak of 40 yr, 81% were female and 19% were male. 64% of the patients were thyrotoxic and 36% were euthyroid at presentation. Thyrotoxi...

Background: Acute drug poisoning remains an important public health problem and represents the second most frequent accidental disease in children. In this study, we identified epidemiological and clinical features of children admitted for acute drug poisoning and related factors associated with suicidal poisoning. Methods: We conducted a retrospective study in the Department of Pediatrics, ...

Limited research has described clinical outcomes that are associated with the type of vascular access in pediatric patients who receive maintenance hemodialysis. This retrospective cohort study examined prevalent pediatric patients who were aged 12 to <18 yr and identified in the 2000 ESRD Clinical Performance Measures Project as receiving in-center hemodialysis. Vascular access type as of Dece...

Variance components for greasy fleece weight in Rambouillet sheep were estimated. Greasy fleece weight was modeled either as repeated measurements on the same trait or as different traits at different ages. The original data were separated according to the age of the ewe at shearing into three classes; 1 yr, 2 and 3 yr, and older than 3 yr. An animal model was used to obtain estimates of geneti...

The Patagonian slab window has been proposed to enhance the solid Earth response ice mass load changes in overlying Northern and Southern Icefields (NPI SPI, respectively). Here, we present first regional seismic velocity model covering entire north-south extent of window. A slow anomaly uppermost mantle indicates warm temperature, low viscosity, possibly partial melt. Low velocities just below...

hemorheology specialists believe that athletes of different sport fields have different hemorheological patterns. the aim of this study was to investigate the effect of sport field on hemorheological variables following acute aerobic exercise. athletes were divided into three groups of 15 subjects (endurance runners: mean±sd: age 24.6±5.2 yr, bf% 6.8±1.6, bmi 21±1; football players: age 22.5±1....

BACKGROUND Evidence from randomized trials on the effects of screening for prostate cancer (PCa) on disease-specific mortality accumulates slowly with increasing follow-up. OBJECTIVE To assess data on PCa-specific mortality in the Rotterdam section of the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial. DESIGN, SETTING, AND PARTICIPANTS A randomized controlled trial...

BACKGROUND Shorter estrogen exposure from puberty onset to peak bone mass attainment may explain how late menarche is a risk factor for osteoporosis. The influence of menarcheal age (MENA) on peak bone mass, cortical, and trabecular microstructure was studied in 124 healthy women aged 20.4 +/- 0.6 (sd) yr. METHODS At distal radius, areal bone mineral density (aBMD) was measured by dual-energy...

BACKGROUND An increasing number of elderly patients are treated for aneurysmal subarachnoid hemorrhage. Given that elderly age is associated with both poor outcome and an increased risk of hydrocephalus, we sought to investigate the interaction between age and hydrocephalus in outcome prediction. METHODS We enrolled 933 consecutive patients treated for subarachnoid hemorrhage between 2002 and...
