[Simplified anesthesia protocol for cataract surgery under topical anesthesia: one year retrospective study].

Introduction: The reduced supply of anesthesiologists in the hospital setting calls for a reconsideration of anesthesia management for ophthalmology patients. Therefore, a simplified management protocol has been designed through close collaboration between the involved specialists for cataract surgery under topical anesthesia (anesthetic eye drops or sub-Tenon's injection).

Materials And Methods: At the conclusion of the visit confirming the need for surgery, the surgeon completes a questionnaire designed to elicit a history of the presence of diabetes mellitus (type I or II), prior organ transplantation, chronic renal insufficiency requiring dialysis, communication difficulties, psychiatric disorders, allergy and/or a complex cataract.

Effects of fluctuating moisture and temperature regimes on the persistence of quiescent conidia of Isaria fumosorosea.

Conidia of Isaria fumosorosea were submitted to three regimes of temperature and moisture to simulate microclimatic conditions which prevail in temperate (43% RH and 28 degrees C to 98% RH and 15 degrees C), subtropical (75% RH and 35 degrees C to 98% RH and 25 degrees C), and arid areas (13% RH and 40 degrees C to 33% RH and 15 degrees C) with daily fluctuating cycles. Germination, conidial viability, and virulence to Spodoptera frugiperda larvae were less affected after 20 days exposure under temperate cycling conditions than under arid and subtropical conditions. Exposure of conidia for 20 days to constant nocturnal simulated conditions of any tested regime weakly affected conidial persistence, whereas diurnal conditions exerted the most detrimental effects of high temperatures.

[Comparison of two methods of cryoconservation of sperm when in very small numbers].

Objective: In case of severe oligozoospermia or following testicular biopsy in case of azoospermia, fertilization remains possible by intracytoplasmic sperm injection (ICSI). However, if there are only a few spermatozoa available to be preserved for a delayed ICSI, these gametes must be cryopreserved according to a specific method. We have found that, using the straw classical technique, less than 2 sperm were recovered at thawing when 20 sperm were frozen and no sperm were available following freezing-thawing of only 1 to 10 sperm per straw.
