Nosocomial infections in a developing Middle East hospital.

The prevalence and pattern of nosocomial infections in a new hospital in the United Arab Emirates is presented. During an 18-month period in which there were 6,544 discharges, 379 nosocomial infections occurred in 310 patients, representing an attack rate of 4.7%. The commonest site of infection was the urinary tract which accounted for 42.2% of the total. This was followed by surgical wound infections, cutaneous infections, bloodstream infections, lower and upper respiratory infections, infected burns and gastrointestinal infections. The most common organisms were Escherichia coli (22.7% of isolates), Pseudomonas species (17.5%) and Staphylococcus aureus (16.7%). Escherichia coli was the most common cause of urinary tract infections and bacteremia; Staphylococcus aureus was the most common cause of surgical wound and cutaneous infections. There was only one Serratia marcescens infection. We observed a high incidence of Pseudomonas infections, particularly of the urinary tract, and Staphylococcal surgical wound and other cutaneous infections, but otherwise our data are similar to nosocomial infection data from US hospitals.

Central compartment pressure monitoring following clubfoot release.

Thirty-nine clubfeet undergoing primary soft tissue release for idiopathic clubfoot deformity had intrinsic compartment pressure monitoring for 36 h after surgery. This was done to determine whether pressures might be elevated to levels, and for durations, such that an intrinsic compartment syndrome might develop. Two groups were identified: in group 1 (23 feet) pressures were never elevated to > 20 mm Hg; in group 2 (16 feet) pressures > 30 mm Hg for a duration of at least 12 h were found. In a subgroup of group 2 (4 of 16 feet), pressures were > 50 mm Hg for at least 12 h. There was no statistical correlation between pressure recordings and surgeon, tourniquet time, severity of deformity, extent of release, and type of cast used. Thus 40% of feet are at risk of developing pressures that could cause an intrinsic compartment syndrome.

Interpleural analgesia in the treatment of severe thoracic postherpetic neuralgia.

Effective, long-lasting pain relief was produced in 26 patients suffering from severe thoracic postherpetic neuralgia by intermittent administration of local anesthetics into the pleural space through a percutaneously placed interpleural catheter. The duration of treatment varied from seven to 21 days. During this period, 30 ml of 0.5% bupivacaine with epinephrine (5 micrograms/ml) were injected every 24 hours. The injections were continued for three days after the patients were pain free or had reached an analgesic plateau. All patients achieved good to excellent pain relief. During a follow-up period of five to 15 months, their level of pain has not increased from the level achieved at the end of the treatment program.
