Serotype distribution and antimicrobial resistance of invasive Streptococcus pneumoniae isolates among Croatian adults during a fifteen-year period (2005-2019).

Aim: To assess serotype distribution, antibiotic resistance, and vaccine coverage against Streptococcus pneumoniae causing invasive infections in Croatian adults from 2005 to 2019.

Methods: In this retrospective study, invasive pneumococcal strains were collected through a microbiological laboratory network with country coverage >95%. Capsular typing was performed with the Quellung reaction.

[Impact of a trauma network on mortality in patients with severe pelvic trauma].

Aim: To evaluate the impact of a regional trauma network on intra-hospital mortality rates of patients admitted with severe pelvic trauma.

Study: Retrospective observational study.

Patients: Sixty-five trauma patients with serious pelvic fracture (pelvic abbreviated injury scale [AIS] score of 3 or more).

[Exceptional medical circumstances: interest of an interhospital support strategy within the North Alps emergency trauma network].

The Northern French Alps Emergency Network (RENAU) has a main objective the improvement of the quality of the care in the field of the emergency medical treatment. With this French medical system, we developed a procedure allowing the detachment of a medical-surgical team of the university hospital to help general hospital team in the event of immediate vital emergency situation with untransportable patient. We reported the successful implementation of this support strategy for a 51-year-old patient arrived in a hospital of the network in extremely serious hemodynamic shock due to an important hemorrhagic pericardial effusion with tamponnade 1 day after percutaneous closure of the patent foramen ovale (PFO).

[Multidrug-resistant tuberculosis management in three French hospitals].

Introduction: Multidrug-resistant tuberculosis (MDR-TB) management is based on specific WHO guidelines.

Objectives: The authors report MDR-TB management, in three French hospitals.

Method: The authors retrospectively included patients with positive sample for multidrug-resistant Mycobacterium tuberculosis (isoniazid+rifampicin) from January 1, 2000 to December 31, 2005.

Mechanisms of macrolide resistance in clinical group B streptococci isolated in France.

Macrolide susceptibility was investigated in clinical group B streptococci obtained from neonates or pregnant women in 2000 in France. Of 490 consecutive isolates, 18% were resistant to erythromycin. The erm(B), erm(A) subclass erm(TR), and mef(A) genes were harbored by 47, 45, and 6% of these strains, respectively.

A YAC contig map of the human genome.

A yeast artificial chromosome library containing 33,000 clones with an average insert size of one megabase of human genomic DNA was extensively analysed by several different procedures for detecting overlaps and positional information. We developed an analysis strategy that resulted, after confirmatory tests, in a YAC contig map reliably covering about 75% of the human genome in 225 contigs having an average size of about ten megabases.

Mechanical ventilation with heated humidifiers or heat and moisture exchangers: effects on patient colonization and incidence of nosocomial pneumonia.

The contribution of ventilator circuit bacterial contamination to the occurrence of ventilator-associated pneumonia remains controversial. In a previous study, we found that the incidence of pneumonia was identical with ventilator circuit changes every 48 h and with no ventilator circuit changes. The present study prospectively assessed whether keeping ventilator circuits clean with a heat and moisture exchanger exhibiting antimicrobial barrier properties affects patient colonization and the incidence of nosocomial pneumonia in patients receiving mechanical ventilation for more than 48 h.

Prospective evaluation of the incidence of bacteremia after protected specimen brushing in ICU patients with and without pneumonia.

To test the hypothesis that the use of protected specimen brushing (PSB) via flexible bronchoscopy does not predispose to bacteremia in ICU patients, we prospectively performed aerobic and anaerobic blood cultures immediately following bronchoscopy with PSB. A total of 123 episodes in 68 consecutive patients with suspected pneumonia were analyzed. Blood cultures were negative in 110 cases (89 percent) and positive in 13 cases (11 percent) (p < 0.

Interaction between pepsin and acid secretion during fundic perfusion in cat and rabbit.

1. The effect of perfusion at pH 5.5 of a Heidenhain pouch on acid and pepsin secretion was studied in cats and rabbits.

Post-prandial lipase, pepsin and acid secretion of a Heidenhain pouch in the rabbit.

The kinetics of the gastric secretion of lipase, pepsin and acid were studied after a meal in Heidenhain-pouch rabbits. After a 24-h fast, feeding immediately stimulated (< 15 min) lipase (x 4.1) and later on pepsin (x 1.

Cholinergic and pentagastrin stimulation of the gastric secretions of acid, pepsin and lipase in the awake rabbit.

Acid, pepsin and lipase secretions were simultaneously studied in awake rabbits with a Heidenhain pouch during cholinergic (carbamylcholine 20 micrograms.kg-1 x h-1) or maximal pentagastrin stimulation (64 mu.kg-1 x h-1).

Variation of gastric lipase secretion in the Heidenhain pouch of the cat.

In the cat, gastric lipase secretion was equally but weakly stimulated by pentagastrin, a major stimulant of acid secretion, and by carbamylcholine, a major stimulant of pepsin secretion. Lipase was also stimulated by fresh liver, which induces a large blood gastrin release and not by canned food, which is a poor gastrin releaser. Lipase output always preceded that of acid an pepsin.

Mapping the whole human genome by fingerprinting yeast artificial chromosomes.

Physical mapping of the human genome has until now been envisioned through single chromosome strategies. We demonstrate that by using large insert yeast artificial chromosomes (YACs) a whole genome approach becomes feasible. YACs (22,000) of 810 kb mean size (5 genome equivalents) have been fingerprinted to obtain individual patterns of restriction fragments detected by a LINE-1 (L1) probe.

Pharmacokinetics of lomefloxacin in healthy volunteers: comparison of 400 milligrams once daily and 200 milligrams twice daily given orally for 5 days.

We evaluated the effect of repeated oral doses (5 days of treatment) on the kinetics of lomefloxacin in volunteers and compared the kinetics after two different regimens, i.e., 400 mg once daily and 200 mg twice daily.
