    Cell surface hydrophobicity and the orientation of certain bacteria at interfaces (1973)

    Notes: Summary Individual cells of Flexibacter aurantiacus CW7 and Hyphomicrobium vulgare ZV580 orientate themselves perpendicularly to the interface in air-water, oil-water and solid-water systems. Electrostatic phenomena probably are not involved in this orientation, since no evidence was found of any localized distribution of positively-charged ionogenic groups on the bacterial surface. It is suggested that the orientation results from a relatively hydrophobic portion of each cell being rejected from the aqueous phase of the system. This property also may be related to the formation of rosettes by these bacteria. Electron micrographs of thin sections of cells sorbed to araldite blocks show that the cell proper is not in contact with the solid surface, but is anchored to it by extracellular adhesive material. The extracellular materials may be of a polysaccharide nature.

    Fluid flow through dural puncture sites (1989)

    Notes: Leakage of artificial cerebrospinal fluid through human dura was measured in vitro after puncture by spinal needles. Fluid loss tailed off in all cases and ceased within 5 minutes in 10% of punctures made with a 22-gauge needle, 28% made with a 26-gauge and 65% made with a 29-gauge needle (p 〈 0.05). The fluid loss was not reduced by alignment of the bevel of the needle parallel to the longitudinal direction of the fibres. Whitacre point needles of 22 gauge produced lower fluid loss than a 22-gauge Quincke point needle inserted across the fibres (p 〈 0.05). Leakage rate was related to needle size, but not related to the alignment of a Quincke point. Little or no leakage occurred with 29-gauge needles.

    Pretreatment with controlled-release morphine for pain after hysterectomy (1996)

    Notes: In a double-blind randomised study, two dosing regimens for controlled-release morphine tablets were compared against placebo to ascertain the extent of prophylactic postoperative pain control in 51 women undergoing abdominal hysterectomy. One group of patients received controlled-release morphine every 12 h for 2 days before surgery, a second group received a single dose of controlled-release morphine 2h before surgery and a third group received placebo. Patient-controlled analgesia system demands were compared for the first 38 h after surgery and 10-point pain scores and McGill pain questionnaires were compared for the first 6 postoperative days and at 6 weeks after surgery. During the first 2 days after surgery, patients reported high levels of pain which were similar in all groups. Pain scores on the third and fourth postoperative days were significantly lower in those who had a single pre-operative dose of controlled-release morphine compared with placebo and those who had been treated with morphine every 12 hfor 2 days (p = 0.043 and 0.024 for third and fourth day respectively). Patient-controlled analgesia demands were also fewer and less variable in those patients receiving the single dose of morphine 2h before surgery. The study shows a beneficial analgesic effect of a single pre-operative dose of morphine, but shows no benefit for a more prolonged pre-operative dosing regimen.
