[Changes in the risk profile and the development of hypertension in the population of Plzen 1987-1989 and 1995-1996]. / Zmeny rizikového profilu a vývoj hypertenze v plzenské populaci mezi lety 1987-1989 a 1995-1996.

OBJECTIVE: To evaluate risk factors and the general risk profile in a longitudinally followed-up cohort of the Plzen population. MATERIAL AND METHODS: The investigation was made in a cohort of 332 men and 280 women selected from the epidemiological study PILS II (Plzen longitudinal study) examined in 1987-1989 and 1995-1995. Both investigations adhered to the standard protocol. Anamnestic data were assessed, anthropometric parameters (BMI). Blood pressure (BP) was assessed by means of a mercury sphygmomanometer using the standard procedure, biochemical parameters were examined from a blood sample on fasting in the routine laboratories of the Faculty Hospital Plzen. Changes of individual factors were evaluated by the paired Wilcoxon test and chi 2 group test resp. The global coronary risk was calculated by means of logistic coefficients from the Framingham study. RESULTS: In the cohort which aged on average by 7.6 years the number of smokers decreased in men by 8.1% and by 3.6% in women. The blood pressure increased significantly in both sexes, there was an increase in the number of hypertensive subjects by 26.8% in men and 21.7% in women. In men there was a significant decrease of non-HDL cholesterol, in women, there was a significant increase of subjects with diabetic dyslipidaemia. The total coronary risk (Framingham score) increased after standard transposition to the age of 60 years only by 0.5% in men and women, which reflects the risk due to increased BP. The standard of treatment of hypertension was quite unsatisfactory. When using criteria SBP > or = 140 and/or DBP > or = 90 mm Hg during the second examination 71% of the patients remained without treatment. The number of subjects not aware of hypertension declined from 54% to 19.3% of subjects. A favourable indicator was the finding that there was a decline of hypertensive subjects with a high coronary risk (> or = 20% from ca 11 to 6%). CONCLUSION: During the investigation period in the cohort which to a certain extent represents the Plzen population a certain improvement of the risk profile occurred in particular as regards smoking and disorders of the lipid spectrum, however not as regards the prevalence and treatment of hypertension. Despite the favourable development in the Czech population in the investigated cohort, obviously at the expense of poor control of hypertension, the average coronary risk did not improve.

[Transmyocardial laser revascularization of the myocardium and coronary reconstruction without extracorporeal circulation]. / Transmyokardiální laserová revaskularizace myokardu a koronární rekonstrukce bez pouzití mimotelního obehu.

The authors report their experience with myocardial revacularization using transmyocardial laser revascularization combined with aortocoronary reconstruction without the use of extracorporeal circulation. The discussion section addresses indications for the procedure, operative tactics, the benefits and limitations of the above technique.

[Quality of life after complex tibial reconstruction]. / Lebenszufriedenheit nach komplexen Unterschenkelrekonstruktionen.

58 patients following Gustilo IIIB open tibial fractures, treated by serial debridements, osteosynthesis and microvascular free tissue transfer were investigated after an average of 6 years. Assessment of life satisfaction was done by means of a proven valid and reliable test instrument (FLZ-"Fragen zur Lebenszufriedenheit"). Further specific questions on treatment satisfaction, aesthetic result, occupation and income were added to this questionnaire. Significant discrepancies of the items recreational activities, income, occupation and partnership, productivity, mobility and pain were evaluated in comparison to available data of healthy west german population. The calculated global index of life satisfaction and health differed significantly from the established index of west german population. Although specific aspects like aesthetic result, donor site morbidity, pain and even function were critically judged, 91% of the patients were satisfied with the long term result of the treatment. None of the patients thought that an initial amputation probably might have been a better solution. The postrehabilitation employment rate was 64%. Limb salvage of Gustilo IIIB fractures by means of a multidisciplinary treatment protocol is able to afford useful and satisfying long time results. However, an impairment of quality of life, at least in specific items has to be considered.
