“Purpose of GANT61 reviewThe authors examine the differential diagnosis for gastrointestinal disorders that should be considered in individuals who present with nonspecific gastrointestinal and nutritional complaints suggestive of an eating disorder.Recent findingsThis review first identifies diseases with which eating disorders are often confused and then explores features in the history, physical examination, and laboratory studies, which can provide clues to the cause of the patient’s symptoms. In addition, it discusses the recommended evaluation and treatments for the gastrointestinal

diseases that most commonly mimic the presentation of eating disorders including Crohn disease (CrD), celiac disease, gastroesophageal reflux disease (GERD), and eosinophilic esophagitis (EoE).SummaryThe ubiquitous nature of the gastrointestinal complaints requires the clinician to consider a broad differential diagnosis when evaluating a patient for an eating disorder.”
“Oxygen is an essential element

of aerobic life, and oxidative metabolism represents a principal source of energy. Nevertheless, oxygen may also be toxic and mutagenic with the potential to cause damage through the production of reactive oxygen species (ROS). ROS generation can be considered a double-edged see more sword. Beneficial effects of ROS occur at moderate concentrations and involve physiological roles in cellular responses to noxia, as in defense against infectious agents, in the function

of a number of cellular signaling pathways and the induction of a mitogenic response. The overproduction of ROS and the insufficiency of an antioxidant mechanism results in oxidative stress (OS), a deleterious process and important mediator of damage to cell structures and tissues. Newborns, especially if preterm, are particularly susceptible to OS and damage due to increased generation of ROS, the lack of adequate antioxidant protection, and the inability to induce antioxidant defenses during the hyperoxic challenge at birth. Hence the “”Oxygen Paradox”": higher eukaryotic aerobic organisms cannot exist without oxygen and without OS, yet oxygen and ROS are dangerous to their existence. Originally, the oxygen paradox described that selleck chemical the injury was aggravated by giving oxygen after hypoxia. Today, we know this is caused by production of oxygen radicals. Therefore, it is mandatory in the handling of newborns to use oxygen as a medication when clinical surveillance indicates a need.”
“Objective: To evaluate whether pre-operative thyroiditis identified by ultrasound (US) could help predict the need for thyroid hormone replacement (THR) following thyroid lobectomy.

Methods: Data from patients who underwent thyroid lobectomy in 2006-2011, were not taking THR pre-operatively, and had >= 1 month of follow-up were reviewed retrospectively. THR was prescribed for relatively elevated thyroid-stimulating hormone (TSH) and hypothyroid symptoms.
