ABSTRACT

Wound botulism is a rare infectious disease that is becoming a frequent complication of parental drug use. Diagnosis is often difficult and based on clinical suspicion. We report the first Italian case of wound botulism due to intramuscular heroin injection in a 48-year-old man with an acute onset of slurred speech and dysphagia. The most considerable finding of electrophysiological study was the reduction in amplitude of compound muscle action potential which should be considered a useful initial electrodiagnostic sign in the clinical context of botulism. Alerting clinicians to botulism is crucial for a rapid diagnosis and appropriate treatment and thus decreasing mortality and complications.

ABSTRACT

The indications to the positioning of central venous catheters (CVCs) are various: parenteral nutrition, chemotherapy, infusion of large amount of fluids or blood products, chronic access for hemodialysis, invasive measurement of hemodynamic variables. Infection is the most important clinical complication associated with the use of CVC, both in terms of incidence and of gravity. Despite the efforts for the optimization of the materials that are more and more biocompatible, the presence of a foreign body in the organism is an ideal substratum for the microbial colonization. The Catheter-Related-Bloodstream-Infections (CRBI) involve a pro-longation of recovery stay, the increase in costs of hospitalization and an increase in morbidity and mortality. The infections are caused by: Staphylococcus aureus and Staphylococcus epidermidis (60%), other bacteria (Enterococ-cus faecalis and Faecium, Pseudomonas aeruginosa; 25%) and among fungi by Candida albicans and Parapsilosis (15%). In order to prevent the CRBI it's important to follow some behavioural norms, both during the positioning of the catheter and in the subsequent assistance to the patient. In case of CRBI it is fundamental to make a sure diagnosis with the positivity for the same pathogen of 2 hemocultures obtained from CVC and from a peripheral vein and then with the microbiological analysis of the tip of the catheter, in order to carry out the specific antibiotic therapy.

ABSTRACT

alpha-Amanitin is an amatoxin known to produce deleterious effects on the liver and the kidneys, when circulating in the blood. It is produced by a particular kind of mushroom called amanita phalloides. Therapeutic options employed to treat mushroom intoxication, such as haemodiaperfusion on activated charcoal, high dosages of penicillin G, oral charcoal, etc., very often failed to act properly and liver transplantation (when a graft is available) appeared to be the only solution. In recent years, as suggest by some authors, it has been postulated that the oxidant effects of alpha-amanitin could be counteracted by the use of antioxidants such as silibinin. High dosages of N-acetyl-cysteine (CAS 616-91-1, NAC), already used as antioxidant in paracetamol poisoning, were successfully used in our Intensive Care Unit (ICU) in the treatment of Amanita phalloides poisoning. In the last two years, 11 patients (mean age of 5-72 = 38.5) were treated for Amanita phalloides poisoning of various degrees, with a protocol (haemodiaperfusion on activated charcoal, high dosages of penicillin G, etc.) further comprehending NAC (fluimucil). All the patients recovered successfully but one (bearing precedent liver disease) needed liver transplantation. Daily monitoring of liver enzymes, creatinine, coagulation, LDH, blood and urinary alpha-amanitin were used to screen the progresses of the patients.

ABSTRACT

We studied 22 patients undergoing total intravenous anaesthesia for both abdominal and superficial surgery. Anaesthesia has been induced and maintained with propofol (1 mg/kg in 20 seconds; 10 mg/kg/h for 10 minutes; 8 mg/kg/h for 10 minutes; 6 mg/kg/h until the end of the operation) and alfentanil (15 mg/kg before the induction and boli of 10-30 mg/kg in the presence of insufficient surgical analgesia). All the patients have been intubated after the administration of vecuronium 0.1 mg/kg, and artificially ventilated with air and oxygen (FiO2 0.4). We observed: 1) haemodynamic stability after the intubation and during surgery; 2) easy control of surgical analgesia; 3) early postoperative recovery, with no correlation with the doses of propofol and alfentanil; 4) absence of postoperative respiratory depression; 5) intraoperative amnesia; 6) low incidence of postoperative side effects. We conclude that, by virtue of the pharmacokinetic characteristics of propofol and alfentanil, most limitations of total intravenous anaesthesia have been overcome.

ABSTRACT

We evaluated the ability of general, regional (interscalene block) and balanced anaesthesia (interscalene block supplemented by general anaesthesia) to manage the problems of shoulder surgery. Our results show that general anaesthesia is not adequate. Interscalene block provides intra and postoperative analgesia, allows an early realization of the postoperative rehabilitation programme and quickens the recovery of shoulder function. Therefore, interscalene block should routinely be performed. The positions of patient and surgeons cause the main disadvantages of anaesthesia with interscalene block alone, ad the control of airway of sedated patients is difficult and performing general anaesthesia in case of insufficient analgesia may be troublesome. Balanced anaesthesia, as compared to regional block alone, allows a safer control of respiration and an easier control of surgical analgesia.

ABSTRACT

We studied three groups of 30 patients each, undergoing minor orthopaedic surgery, anaesthetized with alfentanil (30 micrograms/kg bolus followed by an infusion of 0.3 micrograms/kg/min), thiopental 3 mg/kg and 70% N2O via facial mask. Patients in group I were treated, three minutes before induction, with vecuronium 0.02 mg/kg i.v., while those in group II were premedicated with diazepam 0.15 mg/kg i.m. 30-45 minutes before induction. Group III served as control. Muscular rigidity was evaluated clinically with a subjective score based on a scale of 0 (no rigidity) to 3 (severe rigidity). Diazepam did not give significant protection from muscular rigidity. Vecuronium administration did not significantly reduced the number of patients who became rigid, but significantly decreased the incidence of severe rigidity (p less than 0.005), the mean rigidity score (p less than 0.05) and the incidence of rigidity at the induction of anaesthesia (p less than 0.0005). We also observed a progressively increasing incidence of rigidity with increasing age (not significantly) and body weight (p less than 0.05 total rigidity, p less than 0.01 severe rigidity).

ABSTRACT

The authors have followed the course of the immunological cellular and humoral parameters in 12 patients in the Intensive Care Unit at the University Polyclinic of Messina having grave infections of the respiratory apparatus, for which an antibiotic therapy with azlocillin, semisynthetic penicillin was carried out; all this with the aim of pointing out any possible interferences with the already precarious immune system in such patients. The results obtained seem to exclude any immunodepressing activity by the molecule.
