Background: Hypoxemia is a frequent complication after general anesthesia. It usually takes longer to recover in individuals with respiratory problems. Bakers may suffer from respiratory problems such as asthma. The objective of this study was to compare the occurrence of hypoxemia and duration of supplemental oxygen administration during recovery from general anesthesia in bakers and smokers. ...

Background:  The aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. Materials and Methods: The dose rate from a sample of 192 patients administrated by three different radioactivity of 131I (3.7, 5.55 and 7.4 GBq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three d...

pterygium is characterized by an elastic degeneration of the conjunctiva that extends across the limbos and invades the cornea. the recurrence rate is varied from 25-80% after primary closure to 6% with free conjunctival and iimbal grafts. several adjunctive therapies have been investigated for recurrent pte¬rygium. this article presents a 52-year-old athletic man who was seen for evaluation of...

Background The increasing use of ketamine as a potential rapid-onset antidepressant necessitates a better understanding of its effects on blood pressure and heart rate, well-known side effects at higher doses. For the subanesthetic dose used for depression, potential predictors of these cardiovascular effects are important factors influencing clinical decisions. Since ketamine influences the sy...

BACKGROUND The effects of gonadotrophin-releasing hormone agonist (GnRH-a) administered in the luteal phase remains controversial. This meta-analysis aimed to evaluate the effect of the administration of a single-dose of GnRH-a in the luteal phase on ICSI clinical outcomes. METHODS The research strategy included the online search of databases. Only randomized studies were included. The outcom...

The purpose of this study was to evaluate the acute effects of sublingual nifedipine (10 mg) on left ventricular systolic function (ejection fraction, peak ejection rate, time to peak ejection rate) and diastolic function (peak filling rate, time to peak filling rate, filling fraction during rapid filling) at rest and during exercise using radionuclide angiography in 17 patients with ischemic h...
