[Assessment of anesthesia methods in ophthalmologic surgery by patients, surgeons, and anesthesiologists]. / Bewertung von Narkoseverfahren in der Ophthalmochirurgie durch Patienten, Operateur und Anästhesisten.

BACKGROUND: The purpose of this study was to evaluate anesthesia methods in ophthalmic surgery in elderly people assessed by patients, surgeon, and anesthesiologist using subjective rating scales. PATIENTS AND METHODS: In a prospective, randomized study we compared in 52 (26 vs 26) elderly patients (ASA II and III, mean age 78.7+/-8.6 years) undergoing a cataract operation the satisfaction perceived by patients, surgeons, and anesthesiologists in relation to anesthesia methods [intravenous anesthesia (TIVA) vs balanced anesthesia (BA)] based on a score from 1=best to 6=worse. RESULTS: Patient satisfaction was better in the TIVA group (1.65) than in the patients treated with BA (2.57), p<0.001. Surgeons perceived no difference (BA 1.15/TIVA 1.07). Anesthesiologists preferred TIVA (TIVA 1.5/BA 3.23), p<0.001. CONCLUSION: In this study patients and anesthesiologists preferred TIVA. There was no difference between TIVA and BA as seen by the surgeon.

[Experiences with laser therapy in different forms of glaucoma with open and closed chamber angle]. / Erfahrungen mit der Lasertherapie bei verschiedenen Glaukomformen mit offenem und engem Kammerwinkel.

Results of laser treatment of open-angle and angle-closure glaucomas are communicated. Argon laser trabeculoplasty was performed in 78 eyes with open-angle glaucoma. The most favorable site for photocoagulation was the gone between the pigmented and nonpigmented trabecular meshwork. Forty-two eyes with angle-closure glaucoma were treated by argon laser gonioplasty. This method proved successful in chronic angle-closure glaucoma and for the prophylactic management of acute angle-closure glaucomas. A combination of argon laser gonioplasty and argon laser trabeculoplasty was used in 16 eyes. Both methods were found to be effective in treating certain forms of juvenile glaucoma. A further 11 eyes with acute angle-closure glaucoma were treated by Nd-YAG laser iridotomy, 9 of them successfully.

Proliferation characteristics of lymphoid cells of human bone marrow in health and in chronic renal failure.

Proliferation of bone marrow lymphoid cells of 8 healthy subjects and 7 patients with chronic renal insufficiency was compared using the cytophotometric measurement of the DNA content combined with 3H-thymidine labelling in vitro. In renal insufficiency the cells showed a marked decrease of the proliferation activity. This is apparent from the impaired labelling indices and accumulation of diploid and unlabelled cells. The data suggest that the lymphoid cell proliferation is affected by the same pathophysiological mechanism as that leading to impairment of red cell production. By subclassification according to cytoplasmic basophilia, this proliferation disturbance could be related to the basophilic and not to the pale type of lymphoid cells.
