We studied 94 consecutive patients (age 15 or over) to investigate which aspects of the history and clinical findings help to distinguish seizures from synope and related conditions. Clonic movements or automatism observed by an eyewitness classified an event as a seizure. The seizure group consisted of 41 patients and the syncope group of 53 patients. The(More)
There is evidence in the literature that the decrease of mean power frequency (MPF) during exercise is greater as a muscle becomes more fatigued. After strenuous exercise this phenomenon can last several days. It is usually assumed, however, that the MPF has a good reproducibility. In this study the reproducibility of the MPF of the surface electromyogram(More)
A total of 82 patients (74 girls, 8 boys) are presently participating in an international multicentre trial for treatment of central precocious puberty (CPP) with a slow release gonadotropin-releasing hormone (GnRH) agonist depot preparation: Decapeptyl-Depot (DD). Of these patients, 53 (3 boys) were previously untreated (group 1) and 29 (5 boys) have been(More)
Of 195 cases of juvenile Huntington disease gathered from case descriptions, the sex, age at onset, duration of disease, clinical type, sex of the affected parent, as well as sex, mean age at onset and at death of adult cases in the same pedigrees were noted when available, and the data were investigated for evidence of relationships between different(More)
Remodeling of the left ventricle after myocardial infarction can be documented by calculation of left ventricular volume and mass, using endocardial and epicardial tracings of multilevel multiphase short-axis cine magnetic resonance (MR) imaging series. We assessed left ventricular volume and mass from 8 slices and during 12 phases of the cardiac cycle in(More)
The sensitivity and specificity of urinary cytology in the detection of urothelial tumours using voided urine and applying simple smear preparation and staining techniques have been assessed. Of the 2704 patients under investigation 207 had urothelial tumours. The first urine analysis was positive in 66% of the patients with urothelial carcinoma; an(More)
Of a total study group of 99 patients 56 received intrapleural BCG in three different dosages (5 patients 16×106, 25 patients 32×106, and 26 patients 64×106 culturable particles) following resection treatment for lung cancer. This study group was compared with an historical control population, very closely matched with regard to age, sex, stage of disease,(More)
We found that the distribution of the lipophilic chemotherapeutic agento,p′-DDD (mitotane) among serum (lipo)proteins was altered in hypertriglyceridemia, with relatively moreo,p′-DDD accumulating in the chylomicron and very-low-density lipoprotein (VLDL) fraction. Intralipid, an artificial chylomicron emulsion, or isolated VLDL could extracto,p′-DDD from(More)
Spirometry and krypton-81m lung scans were performed in 17 patients before lobectomy was carried out for bronchogenic carcinoma to determine whether post-operative spirometric values could have been predicted from the pre-operative data. The patients were followed up at 3, 6 and 12 months post-operatively for lung function testing. It emerged from this(More)
The ability of technetium-99m-labelled polyclonal human immunoglobulin G (99mTc-IgG) scintigraphy to predict joint destruction in patients with rheumatoid arthritis (RA) was investigated in this study. The progression of radiographically determined joint destruction in wrists, hands and feet was compared with the results of physical and laboratory(More)
