Pharmacokinetics of rufloxacin once daily in patients with lower respiratory tract infections.

The pharmacokinetic properties of rufloxacin, a new quinolone antibacterial agent, were evaluated in ten patients with lower respiratory tract infections. Patients were given 400 mg of rufloxacin once a day for seven to nine days. Plasma concentrations of the drug were determined by high-performance liquid chromatography and bioassay at regular intervals during treatment. After the first administration, maximal plasma concentrations were 3.17 +/- 0.36 mg/l (mean +/- SEM) and were reached at 4.2 +/- 0.7 h. At the end of treatment peak plasma concentrations increased to 7.26 +/- 0.52 mg/l. Elimination half-life was 38.2 +/- 2.9 h, with a mean extent of accumulation of 2.96 +/- 0.30. Treatment was well tolerated, with no abnormalities noted during routine laboratory examinations. Two days after the last administration, measurable levels of rufloxacin were still observed in plasma, indicating that the long half-life of rufloxacin assures valuable antibacterial activity even after discontinuation of treatment.

Bacterial isolates and cigarette smoking in patients with chronic bronchitis: results from an Italian multicenter survey.

Patients who were cigarette smokers suffering exacerbations of chronic bronchitis were examined in eight outpatient clinics in five regions of Italy, three from the South (Campania, 82 patients; Sicily, 82 patients; and Puglia, 29 patients) and two from North (Lombardy, 33 patients; and Liguria, 50 patients). Haemophilus influenzae was the most frequently isolated bacterium in the patients' sputum (in 30% of the total group), followed by Streptococcus pneumoniae (in 20%), Staphylococcus aureus (in 25%), and Branhamella catarrhalis (in 7%). H. influenzae was the most common bacterium in the South (in 37%) and S aureus in the North (in 13%). Smoking index scores (number of cigarettes smoked daily x years of smoking) were 827 in patients in whom H influenzae was isolated; 691 in patients with S aureus; 599 in patients with S pneumoniae; 542 in patients with B catarrhalis; and 446 in patients in whom no isolates were found. Pulmonary function was most severely decreased in patients positive for H influenzae and S aureus. The results indicate an association between heavy cigarette smoking and lower respiratory tract infections that is influenced by regional differences.

[Non-endocrine growth retardation. Diagnostic and therapeutic indications].

We analyze the most frequent conditions of non endocrine short stature divided into two groups by phenotypic criterion (dysmorphic or not). Furthermore we consider the different causes of short stature in relation to the appearance of stunted growth. The most recent etiopathogenetic advances in knowledge and the main auxologic features of each kind are reported. In the end we evaluate the current therapeutical measures and we analyse the usefulness of non specific treatments.
