Current studies have not conclusively demonstrated an objective and consistent marker of an aberrant stress response; an effect of such a stress response on reproductive outcome; or a benefit of counseling on reproductive outcome in such patients.

Intubation of the airway can lead to laryngotracheal injury, resulting in extubation failure from upper airway obstruction (UAO). A number of factors can help to identify patients who are at greatest risk for postextubation UAO. Three randomized controlled trials demonstrate that prophylactic corticosteroids decrease the risk for postextubation UAO and probably the need for re-intubation.

A total of 450 stool samples were collected from inpatient and outpatient clinics of Pediatric Department, Minia University Hospital, Minia District, Egypt. Two groups of patients were studied, including 200 immunosuppressed and 250 immunocompetent children. Stool samples were subjected to wet saline and iodine mounts. A concentration technique (formol-ether sedimentation method) was carried ou...

The indications for robot-assisted laparoscopic surgery in Urology are expanding as surgical experience with robotic surgery mounts. We describe our experience of performing a laparoscopic robot-assisted excision of a pelvic leiomyosarcoma in an adult.

Phototoxic retinopathy in rats is characterized by a progressive loss of the outer retinal layers. During the neural degenerative phases, a sequence of vascular change occurs. Whole mounts of ink-injected retinal vessels and flat mounts of trypsin-digested retinal vessels show areas of capillary nonperfusion and acellularity and enlargement of retinal capillaries in the deep bed. When the photo...

T H E structure of the mammalian blastocyst has generally been studied on whole mounts in fluid, or on sections of embedded preparations. If the blastocyst of the rabbit is split open and mounted flat, however, the intact cells in their correct topographical relationships may be examined under the high powers of the microscope. This technique, which is quick and simple, may be employed in cytol...

Anthrax causes profound inflammation and systemic shock. A recent study has shown that anthrax lethal toxin represses the transcriptional activity of the glucocorticoid receptor, which is a crucial component of the body's defenses against inflammation. The study reports evidence that lethal toxin blocks the glucocorticoid receptor by inhibiting the p38 mitogen-activated protein kinase pathway. ...
