The objective of this meta-analysis was to determine with cross-sectional and cohort trails whether the use of pacifier increases the risk of early weaning from exclusive breastfeeding before six months of age or cessation of breastfeeding from any breastfeeding before 24 months of age. Additionally, the effect of the age for starting pacifier use on breastfeeding duration was analyzed in the cohort trails. The Medline database was searched (1980 to 2006) with "breastfeed, breastfeeding, or breast feed" and "pacifier, dummy, or soother" as individual keywords.

Background: The aim of this experimental study was to investigate the early effects of interleukin-10 (IL-10) and interleukin-1beta antagonist (anti-IL-1beta) against cellular damage, inflammatory reactivity, lipid peroxidation (LPO), and myeloperoxidase (MPO) activity induced by spinal cord ischemia reperfusion injury (IRI).

Methods: Thirty-two single strain female Albino rats were divided into four groups: control (sham-operated), IRI-alone, IL-10-treated (100 mug/kg), and anti-IL-1beta-treated (1 mg/kg) groups after IRI. IRI was induced by balloon occlusion of the aorta and simultaneous hypovolemia during occlusion.

The goal of this cross-sectional observational study was to determine the incidence of pineal gland calcification (PGC), to investigate the interaction of PGC and aging, and to compare the incidence of PGC among the populations living in Turkey. In a prospective study the rate of PGC on CT scans of 1376 individuals in six referral centers from different regions of Turkey was investigated, with emphasis on effects of climatological parameters and aging on PGC. It was found that the incidence of PGC increased rapidly after first decade and the increase remains gradual thereafter, higher in males than in females for all age groups.

Purpose: To assess the frequency of complications specifically related to local anesthetic infiltration prior to transrectal ultrasound (TRUS)-guided prostate biopsy.

Methods: A total of 200 patients receiving 10 cm(3) (5 cm(3) on each side) of 2% lidocaine injected around the periprostatic nerve plexus under TRUS guidance before prostate biopsy were included. Various complications presumed to be associated with local anesthesia were noted during and after the biopsy procedure.

Background: The purpose of this study was to investigate the effect of EPO on LPO, on ultrastructural findings, and on antiapoptotic bcl-2 and survivin gene expressions after TBI. The authors also compared the activity of EPO with that of MPSS.

Methods: Wistar rats were divided into 6 groups: sham-operated, control, moderate TBI-alone (300 g/cm), TBI + EPO-treated (1000 IU/kg), TBI + MPSS-treated (30 mg/kg), and TBI + vehicle-treated (0.

Inherent abnormalities of myelin have been suggested in the pathogenesis of multiple sclerosis (MS). We investigated myelin in acute disseminated encephalomyelitis (ADEM) patients by magnetic resonance spectroscopy (MRS) and cerebrospinal fluid (CSF) analysis for citrulline, a marker of immature myelin. A citrulline peak was observed in the normal appearing white matter of 7/15 patients and of 1/10 age-matched neurological controls (p=0.

Purpose: To evaluate diffusion changes in the brain parenchyma at the operation site during the first 24 hours following surgery.

Materials And Methods: The study group consisted of 52 patients, 39 who had tumor resection surgery and 13 who had epilepsy surgery. Early postoperative magnetic resonance imaging (MRI) included diffusion-weighted imaging (DWI) and routine contrast-enhanced cranial MRI, together with T2* weighted images on a 3T system.

The distress thermometer (DT) is a useful measure of psychological distress in cancer patients. Our objective was to investigate distress impact on oncology patients in Turkey and determine the optimal cut-off score on the DT for identifying clinically significant distress. One hundred and eighty two cancer patients completed the DT, Problem List (PL), and Hospital Anxiety and Depression scale (HADS), The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30 version 3.

Rhinitis is a common problem with important comorbidities. In order to search the association between rhinitis, allergic phenotypes and other risk factors in Turkish children, a parental questionnaire about allergic diseases and risk factors, and skin prick test (SPT) with 13 inhalant allergens were performed in a population-based sample of 2774 children aged 9-11 yr. Bronchoprovocation testing with hypertonic saline (HS)and total IgE analysis were limited to a subsample of 350 children.

The purpose of this study was to investigate the duration of monitoring, number of seizures recorded, and date and time of occurrence of seizures in different patient groups during video-EEG monitoring (VEEGM). Patients with partial or psychogenic seizures who were admitted to our VEEGM unit between September 1996 and March 2002 were retrospectively evaluated. Duration of monitoring, date and time of occurrence of seizures were identified in each patient.
