Epidemiology of chlamydial eye diseases in a mixed rural/urban population of West Germany

4260 conjunctival specimens of 2850 outpatients with keratoconjunctivitis of presumed infectious etiology were studied. Two thousand six hundred sixty-eight specimens (63%) revealed growth of bacteria, and 80 (2%) growth of fungi. One hundred ninety-nine specimens (5%) were McCoy cell culture or direct stain (monoclonal antibody or Giemsa) positive for Chlamydia trachomatis. two patients had a C. psittaci infection (ELISA techniques). In patients with keratoconjunctivitis of bacterial etiology, overall incidence of McCoy cell culture-proven chlamydial infections was 7%; in the 20 to 30-year age group it was 12.5%. Simultaneous infections of chlamydiae and other bacteria were seen in 34 patients. Since sensitive and specific tests to diagnose chlamydial infections are available, ophthalmologists may be able to prevent these infections by agent-specific antibiotic therapy.     

Improvement in men inpatients in an alcoholism rehabilitation unit: a week-by-week comparison

The Brief Symptom Inventory (BSI), a 53-item psychiatric symptom checklist, was administered to 57 alcoholic inpatients on days 2, 10, 18 and 26 of their 28-day stay in an alcoholism rehabilitation unit at a Veterans Administration hospital. The results of the test show a steady decline in the patients' psychiatric symptomatology from week 1 to week 4 with the most dramatic improvement evidenced between weeks 1 and 2.     

Treatment of Raynaud's syndrome with calcium entry blockers

The authors have presented the results of a 14-day open randomized trial of the efficacy of 3 calcium inlet blocking agents: nifedipine, verapamil and phendilin in 61 patients with Raynaud's syndrome. In the group of patients receiving 30-80 mg of nifedipine (20) there was a significant decrease in the frequency and expression of Raynaud's syndrome attacks, a positive effect of varying degree was noted in 19 patients. The drug raised slightly the skin and muscular blood flow and skin temperature. The use of 120-360 mg of verapamil in 21 patients caused no significant inhibition of Raynaud's syndrome and rise of hemocirculation. Phendilin (150-300 mg) though being comparable with nifedipine in efficacy, often produced side-effects resulting in the drug cancellation (8 out of 20). The efficacy of the calcium inlet blocking agents, especially nifedipine, for therapy of Raynaud's syndrome was emphasized.     

Activity of newer beta-lactam agents against clinical isolates of Bacteroides fragilis and other Bacteroides species.

The in vitro activities of beta-lactam antibiotics against Bacteroides fragilis and B. fragilis group isolates are presented. Clinical isolates from 1986 were compared with strains from 1979 to 1982. Imipenem, ticarcillin-clavulanic acid, and ceftizoxime were the most active agents. Cefotetan was equivalent to cefoxitin against B. fragilis but less active against B. fragilis group isolates. Enhancement of cefotaxime by its desacetyl metabolite was minimal.     

Endoscopic endonasal removal of an intra-suprasellar Rathke's cleft cyst: case report and surgical considerations.

An endoscopic endonasal approach was performed to remove an intra-suprasellar Rathke's cleft cyst. Rathke's cleft cyst are benign lesions, rarely diagnosed because they are often asymptomatic. To the best of our knowledge, at least 475 cases of Rathke's cleft cysts have been reported. They seem to arise from remnants of Rathke's pouch, an invagination of the stomodeum. A 52-year-old woman, complaining of bilateral frontal headaches, was operated on by using an endoscopic endonasal approach, for an intra-suprasellar tumor. The pre-operative diagnosis was non-functioning pituitary adenoma. Intra-operatively a creamy-coloured viscous tissue was found. After the removal of the cyst contents and of the capsule, the suprasellar structures were seen well. The chiasmatic cistern, the chiasm, the pituitary stalk and the pituitary gland were visualized with 0 and 30 degree endoscopes. The pathological findings showed a well-differentiated cuboidal epithelium. The diagnosis was Rathke's cleft cyst. No post-operative complications were observed. The endoscopic technique was particularly suitable in this case, both for the Rathke's cleft features and for an excellent outcome. The Rathke's cleft cyst was easily removed by suction and the cyst wall was entirely removed with curettes and pituitary punches. The hypophysis was distinguished from the cyst and was preserved. The surgical manoeuvres were all done under direct visual control. The absence of nasal packing and of breathing difficulties made comfortable the post-operative outcome. Thus, the endoscopic endonasal approach can be considered the favourite technique in case of either intra- and/or suprasellar Rathke's cleft cysts.
