The effect of a mannose binding protein on macrophage interactions with Candida albicans.

A soluble mannose binding protein (MBP), obtained from rabbit serum, was found to inhibit phagocytosis of Candida albicans by bone marrow derived, cultured murine macrophages. During in vitro incubation of yeast with lymphocyte-free macrophage populations uptake of the yeast was significantly reduced at MBP concentrations of 5 micrograms/ml. A similar reduction in yeast phagocytosis was produced by dextrose, d-fucose, l-fucose, d-mannose and alpha-methyl-d-mannoside but required saccharide concentrations of 25-50 mg/ml.

The utility of preoperative electrocardiograms in the ambulatory surgical patient.

To determine the utility of preoperative screening electrocardiograms (ECGs) among ambulatory surgery patients, we reviewed the charts of 751 consecutive adult patients who underwent ambulatory surgery. Data were collected on demographic characteristics, coexisting medical problems, American Society of Anesthesiologists physical status score, preoperative ECG results, adverse intraoperative cardiovascular events, and postoperative cardiovascular complications. In our study population of relatively healthy outpatients, preoperative ECGs were abnormal in 42.

Arthroscopic surgery of the knee under local anesthesia.

This report delineates the efficacy of local anesthesia in the performance of arthroscopic surgery of the knee. A retrospective review of 500 cases revealed that only three required administration of general anesthesia to successfully complete the procedure. A prospective study comparing fentanyl, midazolam, and fentanyl/midazolam combinations as intravenous supplements was performed.

Unanticipated admission to the hospital following ambulatory surgery.

We conducted a case-control study to identify clinical and demographic risk factors for admission to the hospital following ambulatory surgery. Of 9616 adult patients who underwent ambulatory surgery at a university-affiliated hospital between 1984 and 1986, one hundred were admitted. The most common reasons for admission were pain (18), excessive bleeding (18), and intractable vomiting (17).

Clindamycin enhances murine delayed-type hypersensitivity and anti-candidal activity.

The contact sensitivity response of mice to dinitrofluorobenzene (DNFB), as determined by an epicutaneous painting and subsequent ear challenge assay, was enhanced by clindamycin administration. The optimal augmentation effect of clindamycin required its simultaneous administration at the time of DNFB skin sensitization. Clindamycin also was found to boost both in-vitro and in-vivo murine response to experimental infection with Candida lusitaniae.
