    Notes: An infusion of propofol was compared with intravenous boluses of diazepam as sedation for minor oral surgery under local anaesthesia in 12 healthy patients who had elective bilateral surgical extraction of lower third molars; the patients served as their own controls. Plasma catecholamine, vasopressin and cortisol concentrations were determined from repeated blood samples. The total administered dose of propofol was 3.93 (SD 1.34) mg/kg and of diazepam 0.28 (SD 0.07) mg/kg. No cardiovascular depression or airway problems occurred. Other side effects were also rare but some discomfort on injection was frequent with propofol. Recovery times were faster after propofol than after diazepam as assessed by the Maddox wing and visual analogue scales. Propofol also provided better amnesia compared to diazepam at the time of the extraction of the teeth. Eight of the 12 patients subjectively preferred propofol sedation. There was no hormonal stress response in either group.

    Comparison of propofol and thiopentone for induction of anaesthesia for elective Caesarean section (1989)

    Notes: Propofol 2.5 mg/kg was compared with thiopentone 5 mg/kg as an induction agent for elective Caesarean section. Thirty-two healthy women with cephalopelvic disproportion were included in an open randomised study. The placental transfer of propofol was also studied in 10 other mothers given a single dose of 2.5 mg/kg. The induction characteristics and haemodynamic response to propofol and thiopentone were similar. Side effects were rare with both agents, but propofol caused more discomfort on injection compared to thiopentone. Recovery times were shorter after propofol as evaluated by time to orientation, recovery scoring after anaesthesia and measurements with the Maddox wing. Rapid placental transfer and significant fetal uptake were detected for propofol. There was no significant neonatal depression as assessed by Apgar scores and blood gas analyses. Propofol appears to be a suitable alternative to thiopentone as an induction agent for anaesthesia in elective Caesarean section.

    Comparison between propofol and thiopentone for induction of anaesthesia in children (1988)

    Notes: Propofol 2.5 mg/kg was compared with thiopentone 5 mg/kg in a randomised open study, as an induction agent in paediatric anaesthesia. One hundred and twenty children who were to undergo elective surgery were included in the study. Both propofol and thiopentone produced a rapid and smooth induction with a low incidence of side effects. A similar decrease (10%) in mean arterial pressure was observed with both agents, hut propofol showed better suppression of the haemodynamic response to tracheal intubation. Respiratory upsets occurred less frequently with propofol than with thiopentone, but propofol frequently induced discomfort on injection. Both agents provided satisfactory and controllable induction of anaesthesia and no major adverse reactions occurred during or after anaesthesia. We conclude that propofol is a useful alternative as an induction agent in children.

    Orbits of short period comets captured from the Oort cloud (1996)

    Notes: Abstract Oort cloud comets occasionally obtain orbits which take them through the planetary region. The perturbations by the planets are likely to change the orbit of the comet. We model this process by using a Monte Carlo method and cross sections for orbital changes, i.e. changes in energy, inclination and perihelion distance, in a single planet-comet encounter. The influence of all major planets is considered. We study the distributions of orbital parameters of observable comets, i.e. those which have perihelion distance smaller than a given value. We find that enough comets are captured from the Oort cloud in order to explain the present populations of short period comets. The median value of cos i for the Jupiter family is 0.985 while it is 0.27 for the Halley types. The results may explain the orbital features of short period comets, assuming that the active lifetime of a comet is not much greater than 400 orbital revolutions.

    Notes: Abstract A patient who had had been treated by surgery for spinal echinococcosis in a Mediterranean country emigrated to northern Europe. After surgery, the echinococcosis disseminated and he developed chronic lytic and sinus-draining hydatid disease of the left hip and neuromuscular weakness of the left lower extremity. Seventeen years after the spinal surgery, he was referred to our hip service for a possible total hip replacement (THR) after receiving adequate chemotherapy against echinococcosis for nearly 3 years. Because of the poor results reported by others, we decided against THR; two of the four previous patients described in the current literature who had THR died due to complications.

    Plasma endotoxin and cytokine levels in neutropenic and non-neutropenic bacteremic patients (1995)

    Notes: Abstract Plasma endotoxin, tumor necrosis factor-α (TNF-α), interleukin 1β (IL-1β), interleukin 1 receptor antagonist (IL-1ra), and interleukin 6 (IL-6) concentrations in 69 bacteremic patients were compared with those in 54 nonbacteremic patients suffering from suspected bacterial infections. Only three (11%) of the 27 patients with gram-negative bacteremia showed detectable levels of endotoxin. TNF-α was detected in 6% of the bacteremic patients and in none of the nonbacteremic patients. Median IL-6 levels were significantly higher in bacteremic than in nonbacteremic patients (55 vs. 0 pg/ml, p=0.0008). IL-6 concentrations were similar in neutropenic and non-neutropenic bacteremic patients (median 55 vs. 74 pg/ml). In contrast, neutropenic bacteremic patients had significantly lower concentrations of tIL-1ra than non-neutropenic bacteremic patients (250 vs. 1,950 pg/ml, p〈0.0001). Patients with fatal bacteremia had significantly higher concentrations of IL-6 and IL-1ra than the survivors (median, 450 vs. 40, p=0.012 and 7,600 vs. 420 pg/ml, p=0.0075, respectively). Determinations of endotoxin or TNF-α in patients with suspected bacteremia failed to offer clinically relevant data on the prognosis of these patients. IL-6 levels correlated with both the presence of bacteremia and the risk of death. Granulocytopenic patients with bacteremia had lower levels of circulating IL-1ra than patients with normal granulocyte counts, and these levels correlated with poor outcome.

    Notes: Abstract The first case of cholangitis in whichStomatococcus mucilaginosus was cultured from bile is reported. A 64-year-old male became icteric and was shown to have gallstones in the gallbladder and a common bile duct stone which was removed endoscopically. As the patient remained icteric for a month thereafter the gallbladder with stones was removed. No common bile duct stone was shown by cholangiography perioperatively. The liver biopsy revealed cholangitis andStomatococcus mucilaginosus was grown from the bile. The patient was cured by cholecystectomy without any antimicrobial therapy.

    Notes: Abstract A cluster of seven febrile and severely neutropenic patients who developedClostridium tertium septicemia during a 13-month period is described. The patients had received third generation cephalosporins for 7 to 13 days (mean 9 days) at the timeClostridium tertium was isolated from blood cultures. Two patients had perirectal and one patient pericaecal cellulitis. The organism was also isolated from bronchial secretions in one patient. No patient had diarrhea. Five of six strains tested were resistant to clindamycin (MIC 2–8 µg/ml), and six of seven strains moderately resistant to penicillin (MIC 1–4 µg/ml). In one patientClostridium tertium grew from blood cultures although metronidazole had been administered for two days. Six patients recovered on antibiotic therapy. In view of the unusual susceptibility pattern ofClostridium tertium, an accurate diagnosis of infection with this organism is important for the choice of an appropriate antimicrobial treatment.
