A brain mass in a patient with Behcet's disease: a case report.

Introduction: This case report describes an uncommon presentation of Behcet's disease which manifested as neuro-Behcet's disease. Although it is not the first reported case in the medical literature, it is a possible differential in a patient presenting with a brain tumor. Since the diagnosis of neuro-Behcet's disease depends largely on the clinical picture and medical history, it should be considered prior to opting for invasive diagnostic methods.

Obesity surgery and Ramadan: a prospective analysis of nutritional intake, hunger and satiety and adaptive behaviours during fasting.

Background: Fasting for religious or lifestyle reasons poses a challenge to people who have undergone bariatric surgery. A total fast (abstaining from all forms of nourishment including liquids) during long summer days puts these patients at risk of dehydration and poor calorie and nutrient intake.

Methods: We undertook telephone surveys of 24-h food recall, hunger and satiety scores, medication use, adverse symptoms and depression scores on a fasting day in Ramadan and a non-fasting day subsequently.

Influence of cold on stress ulceration and on gastric mucosal blood flow and energy metabolism.

"Ice-cold" gastric lavage is an important part of the treatment of bleeding from stress ulceration. The purpose of this study was to find out if cooling modifies ischemic injury of the gastric mucosa. Four series of experiments were performed in rabbits.

Mechanism of stress ulcer. Influence of alpha-adrenergic blockade on stress ulceration and gastric mucosal energy metabolism.

In previous reports from this laboratory, it has been proposed that stress ulceration results from a severe gastric mucosal energy deficit due to shock-induced mucosal ischemia. In the experiments described in this report, the hypothesis was further tested by studying stress ulceration and gastric mucosal energy metabolism in rabbits subjected to hemorrhagic shock with or without the concomitant administration of an alpha-adrenergic blocking agent. Our data show that stress ulceration and gastric mucosal energy deficits are significantly less severe when shock is combined with alpha-adrenergic blockade.

Influence of hyperglycemia on survival after hemorrhagic shock.

Terms such as "insulin resistance" and "glucose intolerance" applied to shock-induced hyperglycemia suggest that this state may prejudice survival. However, our data indicate that posthemorrhage hyperglycemia improves short-term survival. Rabbits, either fed until the experiment or fasted for 24 hours, were shocked by rapid removal of 25% of their blood volume (BV) measured by 131IHSA.
