Arterial macrocirculation following ultraviolet irradiation of venous blood in patients with arterial occlusive disease

The influence on macrocirculatory parameters by ultraviolet irradiation of autologous venous blood was controlled in 5 patients. The ultraviolet irradiation did not show any positive effect on different sizes of blood supply. Therefore, as a conclusion the recommendation is given in every case at first to attempt the possibilities of a reconstruction of the arterial vascular system before the use of this therapy.     

Internal medicine treatment of pleural empyema

We made a retrospective analysis with regard to the bacteriology and to the therapy of all patients with pleural empyema who were treated in the district lung hospital from 1. 1. 1982-31. 12. 1986. 92 patients had a non-specific empyema, only 3 patients had a specific empyema. All patients were aspirated repeatedly with physiological saline solution instillation and antimicrobic drug instillation in the pleural cavity. This daily aspiration and lavage was successfully in 65 patients. This method was ineffective in 30 patients. We treated 7 patients of this group by the closed drainage (rubber-tube drain), in 4 patients successfully. 3 patients had to be treated by a surgical operation. An insufficient obliteration of the cavity of empyema occurred also in 23 patients of this group. A systematic daily aspiration for a longer time led to regression of the cavity in 4 cases, whereas a surgical operation was necessary in 19 patients. We consider the daily aspiration and lavage as an effective method in patients in early acute stages of empyema.     

Reference values for nucleosides and nucleobases in cerebrospinal fluid of children

Disturbances in the metabolism of purines and pyrimidines in neurologically affected patients can be reflected by aberrant concentrations of nucleosides and nucleobases in cerebrospinal fluid (CSF). However, normal values, especially for children at different ages, are lacking. We collected 1000 specimens of CSF from subjects ranging in age from newborn to 18 years, who were undergoing a diagnostic lumbar puncture for several clinical indications. Of these, 78 samples could be used retrospectively as a reference according to our criteria. The analyses were performed with a modified HPLC procedure. None of the substances shows age-dependency except uridine and uric acid. Uridine increases with age, and uric acid increases with age in boys older than 12 years.     

Faecal lipids in familial adenomatosis coli

Faecal sterols and bile acids from six patients with familial adenomatosis coli (FPC) and 61 healthy men were analysed preoperatively. Faecal concentrations and secretion of neutral sterols, plant sterols, and degradation products of cholesterol were identical in the two groups. No increase was found in the faecal bile acid excretion, and the distribution of individual bile acids was normal in FPC. The results suggest that the development of adenomas in FPC is not associated with abnormal cholesterol and bile acid excretion.     

Modification of hemorheologic parameters by beta-receptor blockers with special reference to propranolol and talinolol

There are no systematic and complex investigations regarding the hemorheologic action of the betablockers propranolol and talinolol. The results on the other ones are contradictory. On the basis of a critical survey of the literature, in-vitro-experiments and studies in animals (rats) and humans may conclude that there are no remarkable deteriorations of rheological parameters in the therapeutic dose range. This is valid for diseases only where the haemodynamic regulation doesn't prevail.     

Gallstones and previous cholecystectomy in 77- to 78-year-old women in an urban population in Sweden

A randomly selected sample of 120 women, born in 1906-1907 and living in the city of Gothenburg, were invited to an ultrasound examination for gallstone disease. One hundred and nine subjects participated in the study, and among these, 24% gave a history of a previous cholecystectomy, 27% had gallstones, and 49% had no stones in the gallbladder. Among the women with stones in the gallbladder only 35% had associated symptoms. The design of the study enabled a comparison among women with no stones in the gallbladder, with gallstones, and with a previous cholecystectomy. Women with gallstones, previous or present, had a higher body weight, body mass index, skinfold thickness, and serum triglyceride level than subjects without gallstones.     

Prognostic value of various staging and grading systems in proximal colon cancer.

OBJECTIVE: To compare the ability of various methods of staging and grading to predict survival in proximal colon cancer. DESIGN: Retrospective study. SETTING: University hospital, Finland. SUBJECTS: 153 patients with primary proximal colon cancer. MAIN OUTCOME MEASURES: Staging by four classification systems, grading by two grading systems, and survival analysis based on Kaplan-Meier survival curves. RESULTS: In all staging systems the survival curves of different stages differed significantly from each other. The modified Dukes' classification was still the best predictor of survival. Grade of tumours had no significant effect on long term survival, but short term survival was affected adversely by the presence of anaplastic tissue. Tumours with no mucin had a worse prognosis than those that produced mucin. All staging methods were superior to either of the histological grading systems tested as prognosticators. Tumour depth correlated with the operator's clinical impression of radicality of operation, and also predicted survival. CONCLUSION: The clinicopathological modified Dukes' staging system was the most powerful prognosticator in proximal colonic cancer and its use in clinical practice should continue. Even a small amount of anaplastic tissue (> or = 5%) had an adverse effect on short term survival.     

Local status of the urinary stoma--the relation to peristomal skin complications

Sixty-six patients with uretero-ileostomy were investigated with special regards to local status of the urinary stoma, i.e. stomal site, length, size/shape, and peristomal skin. Each variable was defined. In reports from other centres there has been a lack of definitions making it difficult to compare results from different studies. One fifth of our patients had inadequately located stomas and 85% had stomas shorter than 1 cm. The peristomal skin status was assessed according to CPS, Classification of Peristomal Skin. Eight per cent of the patients exhibited severe erythematous/erosive lesions and one fifth pseudoverrucose lesions. The relation between skin lesions and local status of the urinary stoma was analyzed. Patients with inadequately located stomas were more likely to show severe erythematous/erosive lesions and there was a tendency towards patients with stomas shorter than 1 cm, more frequently exhibiting pseudoverrucose lesions.
