Review[Health risks of obesity. Significance of the regional distribution of adipose tissue].
This review concentrates on recent prospective studies concerning evaluation of the health risk of obesity with special reference to the impact of the distribution of the adipose tissue. Analysis of the data indicates that adipose tissue localized to the abdominal region (especially intraabdominal fat) is associated with an enhanced risk profile including elevated levels of triglycerides and insulin, low levels of high density lipoprotein-cholesterol and elevated blood pressure. Abdominal obesity, determined by the waist/hip ratio, was associated with cardiovascular disease, premature death and non-insulin demanding diabetes mellitus. ⋯ In conclusion, obesity and the abdominal localization of adipose tissue seem to be two separate entities with different pathogenesis and clinical consequences. The abdominal obesity is the type which is predominantly associated with enhanced health risks. These associations may result in an altered strategy of treatment of the obese population.

[Serum concentration of lidocaine and its active metabolite monoethylglycinexylidine during fiberoptic bronchoscopy under local anesthesia].
Fiberoptic bronchoscopy was performed in local anaesthesia with lidocaine in 16 patients. Serum concentrations of lidocaine and its active metabolite monoethylglycinexylidide (MEGX) were measured at regular intervals up to 120 min. after administration. Lidocaine was administered as aerosol in the upper respiratory tract and as solution in the bronchial tree. ⋯ The highest median S-MEGX concentration, 1.7 mumol/l, was measured 120 min. after administration. The highest individual S-MEGX was 3.5 mumol/l. The highest, although insignificant, correlation coefficients were found between lidocaine dose expressed in mg/kg body weight and S-lidocaine and S-MEGX.
