Diflunisal compared with naproxen in the treatment of osteoarthrosis of hip or knee: a double-blind trial.

A randomized double-blind trial was carried out in 20 patients with osteoarthrosis of the hip or knee to compare the efficacy and tolerance of treatment with diflunisal or naproxen. During the first 4 weeks, patients received either 250 mg diflunisal or 250 mg naproxen twice daily and this was increased by 250 mg daily in 5 patients on diflunisal and in 3 on naproxen for the second 4 weeks of the trial. The results of subjective assessments made before and at the end of Week 8 showed a trend in favour of diflunisal for improvement of symptoms, except for weight-bearing pain which was improved in only 1 patient in each group. More of the patients receiving diflunisal than naproxen considered treatment to have been satisfactory, and rated their response as equally as good as or better than previous medication. Diflunisal produced significantly high incidence of gastro-intestinal upsets, leading to the withdrawal of 2 patients at Week 4.

Giant, mushroom-shaped osteoma of the orbit originating from the maxillary sinus.

A 53-year-old woman had a six-month history of proptosis, pain, and decreased vision in the right eye. Skull X-ray films and polytomography demonstrated a giant, mushroom-shaped osteoma originating from the roof of the maxillary sinus and invading the orbit. The tumor was removed by a lateral orbital approach with prompt resolution of proptosis and pain, and recovery of normal vision and ocular motility. This patient is one of 34 patients with 38 paranasal sinus osteomas examined here in the last 25 years. Only six patients have had orbital symptoms or signs.

Bacterial endocarditis in England in the 1970's: a review of 70 patients.

The features of 70 cases of bacterial endocarditis are reported. Streptococcus viridans was the cause in 45 per cent, staphylococci in 27 per cent, and enterococci in 7 per cent. Rheumatic heart disease was the predisposing factor in less than one quarter of patients and in almost half there was no obvious pre-existing cardiac disease. Apart from cardiac murmurs and pyrexia, the classical features of infective endocarditis were uncommon, haematuria being observed in less than one-third. Most patients were over the age of 30, one-third more than 60 years of age and the peak incidence occurred in the seventh decade. The mortality was 34 per cent, being highest in infection caused by Staphylococcus aureus. Adverse prognostic features included cardiac failure, advanced age and peripheral embolization. One-third of infections were caused by bacteria resistant to penicillin.

Fetal bradycardia without fetal distress: case presentation and review of the literature.

A case of a term pregnancy with a persistent fetal heart rate of 65 to 80 beats/min is presented. Initially this was presumed to be due to congenital heart block. Subsequent fetal ECG revealed blocked atrial extrasystoles. Review of the literature showed 31 previously reported cases of heart block diagnosed in utero. A review of this literature is discussed and the importance of differentiating bradycardia due to heart block from bradycardia due to fetal distress is emphasized.

Nitrate reductase from anaerobically grown Rhizobium japonicum.

The activity of nitrate reductase in Rhizobium japonicum is controlled by oxygen tension, and not by nitrate. The enzyme from R. japonicum grown anaerobically in the presence of nitrate resembles that from bacteroids in having a molecular weight of about 69000 daltons; the enzyme from aerobically grown cells ahs a molecular weight of about 170000 daltons. Both types of enzyme have similar Km values, but differ in their sensitivity to KCN.

Response of osteoarthritis to ibuprofen or flurbiprofen.

Flurbiprofen and ibuprofen, two propionic acid derivatives with anti-inflammatory and analgesic activity, were compared in a double-blind multiclinic study in 195 patients with osteoarthritis of the peripheral joints. The patients were given 80 mg/day flurbiprofen or 1600 mg/day ibuprofen for six weeks. Pain, subjective evaluation and functional tests improved significantly in both groups. There were no statistically significant differences between the two treatments in any of the responses. Gastro-intestinal side-effects, generally mild, developed in 5-6% of the patients.
