Randomized Controlled Trial Clinical Trial
Controlled trial of adjuvant chemotherapy with cyclophosphamide, methotrexate, and fluorouracil for breast cancer.
327 patients with cancer of the breast and involvement of axillary lymph nodes were randomised, after total mastectomy and axillary clearance, to receive either no additional treatment or oral cyclophosphamide 80 mg/m2 on days 1-14, intravenous methotrexate 32 mg/m2 on days 1 and 8, and intravenous fluorouracil 480 mg/m2 on days 1 and 8 (CMF), which was repeated every 28 days for twelve cycles. There was a significantly longer relapse-free survival (RFS) in patients treated with CMF. ⋯ Dose of chemotherapy did not have a significant effect on RFS. Survival was not influenced by treatment.

Randomized Controlled Trial Clinical Trial
Anti-lipopolysaccharide immunotherapy in management of septic shock of obstetric and gynaecological origin.
Freeze-dried human plasma rich in anti-lipopolysaccharide (anti-LPS) immunoglobulin G was used to treat septic shock (systolic pressure less than or equal to 80 mm Hg, central venous pressure greater than or equal to 6 cm H2O) in obstetric and gynaecological patients. Mortality in conventionally treated patients was 9/19 (47.4%) compared with 1/14 (7.1%) in anti-LPS-treated patients. ⋯ The development of complications of septic shock was much reduced in the treated group. Anti-LPS thus appears significantly to reduce mortality and morbidity in septicaemia.

Randomized Controlled Trial Clinical Trial
Protection of infants against rotavirus diarrhoea by RIT 4237 attenuated bovine rotavirus strain vaccine.
A randomised, double-blind, placebo-controlled trial was conducted to evaluate the ability of RIT 4237 live attenuated bovine rotavirus (subgroup 1) vaccine strain to protect against natural rotavirus infection in children. 178 infants aged 8 to 11 months received a single oral dose of RIT 4237 vaccine or placebo and were followed up serologically and clinically during a subgroup 2 rotavirus epidemic. No side-effects attributable to the vaccine were observed. ⋯ The 2 children in the vaccine group with rotavirus diarrhoea were regarded as primary vaccine failures since they had no detectable serum antibody responses after vaccination. Vaccine prepared from RIT 4237 strain of attenuated bovine rotavirus thus seems to protect children against heterologous subgroup 2 rotavirus diarrhoea.

Randomized Controlled Trial Clinical Trial
Pancuronium prevents pneumothoraces in ventilated premature babies who actively expire against positive pressure inflation.
Preterm infants who were making expiratory efforts against ventilator inflation were randomised to be paralysed with pancuronium or to receive no paralysing agent during ventilation. Pneumothoraces developed in all 11 unparalysed babies but in only 1 of 11 (p less than 0.0004) of those managed with pancuronium, which had no serious side-effects. In 34 infants excluded from the trial because they were not breathing against the ventilator, no pneumothoraces developed.

Randomized Controlled Trial Clinical Trial
Effect of catheter tunnelling and a nutrition nurse on catheter sepsis during parenteral nutrition. A controlled trial.
In a three-year controlled trial of subcutaneous catheter tunnelling as a method of reducing total parenteral nutrition (TPN) catheter sepsis 99 silicone catheters (52 tunnelled, 47 untunnelled) were inserted into the subclavian (94%) or jugular (6%) veins under aseptic conditions. The influence of a nutrition nurse, who joined the nutrition team after 18 months, on catheter sepsis rate was also documented. Catheter sepsis was confirmed in 13 of 47 (28%) untunnelled catheters and only 6 of 52 (11.5%) tunnelled catheters (p less than 0.05). ⋯ There was no significant difference between tunnelled and untunnelled catheters in sepsis rates after the arrival of the nutrition nurse. Although 85% patients had concurrent internal sepsis, the pathogens implicated in catheter sepsis came from superficial sites in 16 of 19 cases (p less than 0.01). Rigorous aseptic nursing care is thus the most significant factor in the reduction of TPN catheter sepsis, but tunnelling can reduce sepsis rate when nursing care is suboptimum.
