[Appendicitis: microbial interactions and new pathogens].

The Authors present an exhaustive review on microbial agents of appendicitis by means of literature and personal research data. Thus, a detailed analysis is made on common autochthonous agents and their pathogenetic interactions and on less common exogenous bacterial, viral, mycotic, protozoan and helminthic agents with emphasis to the role of Yersinia enterocolitica. In fact this bacterium seems responsible for 3% to 8% of cases in accordance with literature and personal research data (more detailed, Y. enterocolitica has been isolated in 3.8% of 208 inflamed appendices from both pediatric and adults surgical florentine patients). At the end, the pathogenetic role of "new" other bacteria, like Buttiauxella agrestis, Aeromonas hydrophila, Arizona, Streptococcus lactis, is debated on the basis of a personal study.

Oxygen tension monitoring in uremic patients during hemodialysis treatment.

The aim of this study was to evaluate the influence on cerebral and cutaneous vascular regions of PaO2 reduction during acetate dialysis, by monitoring conjunctival oxygen tension (PcjO2) and transcutaneous oxygen tension (PtcO2) during hemodialysis (HD) treatment. The study was performed on 23 patients with end-stage renal disease in chronic HD. All patients underwent dialytic treatment with cuprophan membranes and acetate containing dialysate. PcjO2 and PtcO2 were recorded and PaO2 and arterial carbon dioxide tension (PaCO2) were also measured. Results of the study show that hypoxemia during acetate dialysis with cuprophan membranes is not accompanied by changes of PcjO2 and therefore by changes in cerebral oxygenation. Moreover, PtcO2 remains constant during dialysis treatment. Furthermore, maintenance of normal oxygen tension at the conjunctival level is not obtained at the expense of the peripheral region of the skin.

[Clinical evaluation of the efficacy of Ro 15-1788, Anexate after balanced intravenous anesthesia with flunitrazepam and fentanyl].

Benzodiazepines are widely used as neuroleptics in anaesthesia, but they give rise to drowsiness at the end of surgery. Anexate is an imidazobenzodiazepine with specific antagonistic activity for benzodiazepines. We have administered 0.2 mg i.v. of the drug to 20 adult patients after anaesthesia with tiopentale (250 mg), pancuronium bromide (0.07 mg.kg-1), flunitrazepam (2 mg) and fentanyl (0.10 mg); after the first dose fentanyl was administered (0.10 mg) about every 30 minute. Analgesia was supplemented with nitrous oxide 66%. Blood pressure and heart rate did not changes significantly after Anexate; respiratory volume increased significantly in all cases (ANOVA P less than 0.001). Consciousness was rapidly resumed in all cases and patients demonstrated to be oriented in time and space soon after Anexate. In 14 out of 20 patients drowsiness reappeared after about 30 minute and further doses of 0.1 mg of the drug (to a maximum of 0.4 mg in some cases) were necessary. Side effects were rare and slight, their occurrence depending on the speed of administration. In our opinion a total dose of 0.3 to 0.4 mg Anexate is need to fully antagonize the sedative effect of 2 mg flunitrazepam.
