TL;DR: The effects of rimonabant treatment in obese patients with cardiovascular risk factors to usual obesity pharmacological treatment is compared.
Abstract: Rimonabant is the first CB1 receptor inhibitor available in the Brazilian market. This new drug has been approved for the treatment of obese or overweight patients associated with cardiovascular risk factors. In this article it is compared the effects of rimonabant treatment in obese patients with cardiovascular risk factors to usual obesity pharmacological treatment.

TL;DR: Patients with eating disorders present with various gastrointestinal disturbances such as postprandial fullness, abdominal distention, abdominal pain, gastric distension, and early satiety, with altered esophageal motility sometimes seen in patients with anorexia nervosa.
Abstract: The two most clinically serious eating disorders are anorexia nervosa and bulimia nervosa. A drive for thinness and fear of fatness lead patients with anorexia nervosa either to restrict their food intake or binge-eat then purge (through self-induced vomiting and/or laxative abuse) to reduce their body weight to much less than the normal range. A drive for thinness leads patients with bulimia nervosa to binge-eat then purge but fail to reduce their body weight. Patients with eating disorders present with various gastrointestinal disturbances such as postprandial fullness, abdominal distention, abdominal pain, gastric distension, and early satiety, with altered esophageal motility sometimes seen in patients with anorexia nervosa. Other common conditions noted in patients with eating disorders are postprandial distress syndrome, superior mesenteric artery syndrome, irritable bowel syndrome, and functional constipation. Binge eating may cause acute gastric dilatation and gastric perforation, while self-induced vomiting can lead to dental caries, salivary gland enlargement, gastroesophageal reflux disease, and electrolyte imbalance. Laxative abuse can cause dehydration and electrolyte imbalance. Vomiting and/or laxative abuse can cause hypokalemia, which carries a risk of fatal arrhythmia. Careful assessment and intensive treatment of patients with eating disorders is needed because gastrointestinal symptoms/disorders can progress to a critical condition.

TL;DR: The endocannabinoid system has important physiological functions not only in the central nervous system but also in peripheral tissues, and the pharmacological modulation of the over-activity of this system could be useful in the treatment of the metabolic syndrome.
Abstract: Cannabis sativa (also known as marijuana) has been cultivated by man for more than 5,000 years. However, there was a rise in its use in the 20th century for recreational, religious or spiritual, and medicinal purposes. The main psychoactive constituent of cannabis, whose structure was identified in the 1960's, is Δ9-tetrahydrocannabinol. On the other hand, the discovery of cannabinoid receptors and their endogenous agonists took place only very recently. In fact, the first cannabinoid receptor (CB1) was cloned in 1990, followed 3 years later by the characterization of a second cannabinoid receptor (CB2). Since the 19th century, the use of cannabis has been reported to stimulate appetite and increase the consumption of sweet and tasty food, sometimes resulting in significant weight gain. The recent description of the endocannabinoid system, not only in the central nervous system but also in peripheral tissues, points to its involvement in the regulation of appetite, food intake and energy metabolism. Consequently, the pharmacological modulation of the over-activity of this system could be useful in the treatment of the metabolic syndrome. The endocannabinoid system has important physiological functions not only in the central nervous system but also in peripheral tissues. The activation of central CB1 receptors, particularly in hypothalamic nuclei and in the limbic system, is involved in the regulation of feeding behavior, and especially in the control of the intake of palatable food. In the periphery, cannabinoid receptors are present in adipocytes, skeletal muscle, gastrointestinal tract and liver, modulating energy metabolism.

TL;DR: The objective was to report the increased awareness of eating disorders and that it is likewise important to recognize that organic pathology (achalasia) can cause symptoms that may mimic an eating disorder and lead to misdiagnosis.
Abstract: Eating disorders are commonly considered diagnoses in young women who present with unexplained weight loss and vomiting. Our objective was to report the increased awareness of eating disorders and that it is likewise important to recognize that organic pathology (achalasia) can cause symptoms that may mimic an eating disorder and lead to misdiagnosis. Two case reports are presented and a review of the existing literature is provided. In the first patient, initial diagnosis of nonclassified eating disorder based on a pubertal conflict was made, and 3.5 years later diagnosis of primary achalasia was established. Atypical bulimia nervosa was initially suspected in the other case, but diagnosis of achalasia was established at an early stage of evaluation. The exclusion of organic disease must be a priority, even if a psychotherapeutic intervention may be needed in the global care of eating disorder patients. Esophageal achalasia should be considered in anyone presenting with difficulty swallowing or dysphagia, even if other features suggest anorexia nervosa or bulimia nervosa.

TL;DR: Increased awareness of achalasia in ED treatment settings can help facilitate detection of achalasia, thereby reducing treatment delay, and reduce treatment delay.
Abstract: Introduction Achalasia is a rare oesophageal motility disorder characterized by physical, behavioural and psychosocial features that are strikingly similar to eating disorders (ED). Method A literature search of PubMed and Google Scholar identified 36 cases of achalasia from 11 countries misdiagnosed as ED between 1980 and 2013. Results On average, the typical misdiagnosed case was an 18-year-old female with an average weight loss of 16.2 kg. Vomiting behaviour in achalasia was distinguished by occurring after both solids and liquids, occurring in public, and worsening at night or while lying down, and was associated with pain relief. Manometric investigations of oesophageal functioning in clinical ED samples are few and have shown little evidence of dysmotility. Discussion Achalasia and ED share numerous clinical features including weight loss and vomiting. Pain associated with swallowing difficulties may lead to an increasingly restricted pattern of eating and food avoidance. Increased awareness of achalasia in ED treatment settings can help facilitate detection of achalasia, thereby reducing treatment delay. © 2014 The Authors.

TL;DR: The clinical case of a 46-year-old woman with a long-term delusion of triplet pregnancy, and recurrent vomiting is presented, illustrating the difficulty of establishing clinical-surgical diagnoses in psychotic patients.
Abstract: Abnormal eating behaviour among psychiatric patients is associated with several psychiatric conditions, but may also be caused by a comorbid physical condition. Clinical assessment of a psychiatric patient is often challenging, which contributes to an increased rate of undiagnosed medical conditions and an increased mortality rate. We present the clinical case of a 46-year-old woman with a long-term delusion of triplet pregnancy, and recurrent vomiting. She experienced intense weight loss and eventually faced a life-threatening situation due to achalasia, which was incidentally discovered on a chest X-ray during her second psychiatric hospitalization, after several other tests, including upper digestive endoscopy, returned normal results. After a successful laparoscopic Heller's myotomy, her digestive symptoms greatly improved. This report illustrates the difficulty of establishing clinical-surgical diagnoses in psychotic patients, as some delusions seem to explain clinical complaints, masking and delaying the diagnosis of comorbid conditions.
