Hereditary prolidase deficiency in 2 sisters with therapy-resistant leg ulcers

Two sisters with hereditary prolidase deficiency are presented. Recurrent and painful leg ulcers are the predominant feature.     

Significance of duodenogastric reflux in the pathogenesis of primary stomach cancer

Duodenogastric reflux has often been discussed as a causative factor in the pathogenesis of gastric carcinoma. The author's clinical examinations of 135 patients with primary cancer of the stomach revealed slight increase in duodenogastric reflux. Yet, apart from these findings, no correlations were found to exist between reflux incidence and tumour localisation nor between histological tumour type and tumour size.     

Knee ligament injuries in adolescents. Eight year follow-up of conservative management

We have reviewed 32 patients who sustained a substantial knee ligament injury during adolescence when their knee epiphyses were open. They were all treated non-operatively and re-examined and evaluated in detail after an average of eight years. There were 25 Grade II partial tears and seven Grade III complete tears. After Grade II injuries the functional results were excellent or good, though static instability had not improved from the initial post-traumatic examination. The long-term results of Grade III injuries were poor, because of chronic functional instability, with continuous symptoms and some post-traumatic osteoarthritis. The results of non-operative treatment for Grade III ligament injuries were not acceptable.     

Disposition and pharmacokinetics of [14C]finasteride after oral administration in humans.

The disposition of [14C]finasteride, a competitive inhibitor of steroid 5 alpha-reductase, was investigated after oral administration of 38.1 mg (18.4 microCi) of drug in six healthy volunteers. Plasma, urine, and feces were collected for 7 days and assayed for total radioactivity. Concentrations of finasteride and its neutral metabolite, omega-hydroxyfinasteride (monohydroxylated on the t-butyl side chain), in plasma and urine were determined by HPLC assay. Mean excretion of radioactivity equivalents in urine and feces equaled 39.1 +/- 4.7% and 56.8 +/- 5.0% of the dose, respectively. The mean peak plasma concentrations reached for total radioactivity (ng equivalents), finasteride, and omega-hydroxyfinasteride were 596.5 +/- 88.3, 313.8 +/- 99.4, and 73.7 +/- 11.8 ng/ml, respectively, at approximately 2 hr; the mean terminal half-life for drug and metabolite was 5.9 +/- 1.3 and 8.4 +/- 1.7 hr, respectively. Of the 24-hr plasma radioactivity, 40.9% was finasteride, 11.8% was the neutral metabolite, and 26.7% was characterized as an acidic fraction of radioactivity. Binding of [14C]finasteride to plasma protein was extensive (91.3 to 89.8%), with a trend suggesting concentration dependency (range 0.02 to 2 micrograms/ml). Little of the dose was excreted in urine as parent (0.04%) or omega-hydroxyfinasteride (0.4%). Urinary excretion of radioactivity was largely in the form of acidic metabolite(s)--18.4 +/- 1.7% of the dose was eliminated as the omega-monocarboxylic acid metabolite. Finasteride was scarcely excreted unchanged in feces. In humans, finasteride is extensively metabolized through oxidative pathways.(ABSTRACT TRUNCATED AT 250 WORDS)     

Diagnostic value of 24-hour simultaneous EEG and ECG monitoring of patients with heart diseases and atypical consciousness disorders]

In 24 patients with diagnostically not clear, short, recurrent episodes of consciousness disturbances and heart diseases and/or a history of arrhythmia simultaneous 24-hour recording was done of eeg and ecg. In the differential diagnosis epilepsy was considered, especially since in most cases routine eeg records demonstrated slight episodic changes. During 24-hour recording in 8 cases typical episodes of consciousness disturbances developed but in none of them these episodes were associated with arrhythmia which ruled out their cardiogenic origin. In 2 cases EEG recording served for establishing the diagnosis of partial complex seizures, 2 patients had hyperventilation syncope, one had TIA, in the remaining 3 cases absence of eeg and ecg changes during these episodes and coexistence of anxiety neurosis suggested functional origin. So the combined 24-hour eeg+ecg recording made possible establishing of diagnosis in 1/3 of these patients, enabling adequate treatment to be instituted.
