AIMS To describe a large series of children with anoxic-epileptic seizures (AES)--that is, epileptic seizures induced by syncopes. METHODS Retrospective case-note review in a tertiary paediatric neurology unit. For all 27 children seen with a definite diagnosis of AES between 1972 and 2002, a review of clinical histories, videotapes, and EEG/ECG studies was undertaken. Main outcome measures w...

OBJECTIVES/HYPOTHESIS To report the preliminary results of the Ototronix MAXUM middle ear implant for treatment of severe high-frequency sensorineural hearing loss. STUDY DESIGN Case series with chart review. METHODS Six consecutive ears with severe high-frequency sensorineural hearing loss (≥75 dB HL at 2, 3, and 4 kHz) and poor aided word recognition performance (≤60% single words) underw...

OBJECTIVE Urinary iodine concentration is the prime indicator of nutritional iodine status and is used to evaluate population-based iodine supplementation. In 1994, WHO, UNICEF and ICCIDD recommended median urinary iodine concentrations for populations of 100- 200 micro g/l, assuming the 100 micro g/l threshold would limit concentrations <50 micro g/l to </=20% of people. Some scientists felt t...

A surface EMG technique is described which was developed to provide an objective measure of paraspinal muscle function in patients with LBP. The device, referred to as a Back Analysis System (BAS) records changes in spectral and amplitude parameters from 6 EMG electrodes during a series of fatiguing isometric tasks that rely on visual force-feedback. Changes in the EMG median frequency, a fatig...

OBJECTIVE To identify the frequency and median duration of breast-feeding in children aged 0-24 months in the city of Ouro Preto, Brazil. METHODS A cross-sectional study was carried out to identify the median duration of breastfeeding in children aged 0-24 months. A sample of 229 children from 1800 households was drawn by clusters at three different occasions and stratified according to the a...

PURPOSE To investigate the process of fatigue in orbicularis oris muscles by analyzing the median frequency of electromyographic signal and the referred fatigue time, according to the breathing mode and the facial pattern. METHODS The participants were 70 children, aged 6 to 12 years, who matched the established criteria. To be classified as 36 nasal-breathing and 34 mouth-breathing children,...

BACKGROUND Localized sites of high frequency during atrial fibrillation (AF) are used as target sites to eliminate AF. Spectral analysis is used experimentally to determine these sites. The purpose of this study was to compare dominant frequencies (DF) with AF cycle length (AFCL) of unipolar and bipolar recordings. METHODS AND RESULTS Left and right atrial endocardial electrograms were record...
