Rhabdomyolysis is an acute skeletal muscle disorder characterized by altered integrity of the cell membranes of muscle fiber cells. It can be related to a variety of factors: muscular trauma, muscle enzyme deficiencies, infections, drugs, toxins, alcohol ingestion, endocrinopathies and electrolyte imbalances such as hypokalemia. We report the case of a 46-year-old woman admitted to the Emergency Department for frequent episodes of vomiting associated with food intake in the last two weeks, general muscular weakness and myalgia. Physical examination on admission was unremarkable, except for a symmetrical and dominantly proximal muscular weakness of all four extremities. Blood pressure was 116/70 mmHg with a sinus bradycardia (53 beats/min) on the electrocardiogram. Laboratory tests showed a metabolic alkalosis with marked hypokalemia (K+= 1.9 mEq/l) and elevation of muscular enzymes (myglobin= 993 ng/ml, troponin T= 0,10 ng/ml e CK= 1113 U/l). No symptoms of recurrent rhabdomyolysis were reported, patient denied alcohol consumption and there was not clinical evidence of hyperthyroidism. A iatrogenic etiology could not be excluded for certain because patient was in therapy with lansoprazole (Naranjo algorithm 3/13) but, revealing medical history that she underwent a laparoscopic adjustable gastric banding for the treatment of a severe obesity, we focused our attention on hypokalemia, due to persistent vomiting. Fasting, administration of metoclopramide and infusion of potassium chloride resulted in steady improvement of clinical conditions and normalization of electrolyte imbalance. At the clinical follow-up of three months, after partial deflation of the gastric banding, the patient was asymptomatic with muscular enzymes and potassium levels in the normal range. Authors discuss the pathophysiologic mechanisms of these alterations.

A 56-year-old woman with obesity and poorly controlled diabetes mellitus presented with a two-day history of abdominal fullness and vomiting. No fever, flank pain or dysuria was present. On admission, her blood urea nitrogen concentration was 74 mg per deciliter and the serum creatinine concentration was 3.5 mg per deciliter. Laboratory data revealed an elevated white blood cell count (11.72 x 10(3)/ml), blood sugar (826 mg/dl), pyuria (WBC 30-50/HPF) and negative urine ketone. A plain abdominal radiograph revealed right renal stones and localized air accumulation at the left upper abdominal area.

The worldwide prevalence of obesity continues to increase, with devastating implications for overall health. Epidemiological trends indicate the primary contributors are environmental (e.g., increased caloric intake, lack of exercise), although the evidence is surprisingly equivocal. Increased body mass index (BMI) is associated with an increase in all-cause mortality and in diseases related to this increasing mortality rate, such as diabetes mellitus, cardiovascular disease, and cancer, including those of the gastrointestinal system. Some of these associations are even more pronounced when obesity is measured by waist-to-hip ratio, a marker of visceral adipose tissue, versus BMI. Higher BMI is related to increased risk of developing gall stones, and obese patients experience GI symptoms, such as vomiting and diarrhea, more often compared with those of normal body mass. Although the exact cause remains uncertain, these symptoms may be connected to eating habits or to changes in gastrointestinal motility.

Epigenetic influences on the fetus's genotype have been shown to occur during intrauterine life. Experimentally imposed extracellular dehydration in pregnant rats (a model for human hyponatremia caused by gravidic vomiting) brings about a dramatic enhancement of salt appetite not only in the dam, but also in offspring when they reach adulthood. This phenomenon has been verified in human newborn infants and adults whose mothers experienced nausea and/or vomiting during pregnancy. Alcohol consumption during pregnancy enhances its palatability for the offspring. Ingestion of olfactory test substances like anise or carrot by the mother during pregnancy gives rise to a preference for the same testants in the offspring. Under- or overnutrition in the pregnant mother appears to play a role in reprogramming the postnatal regulation of both feeding and fat reserves in offspring. Both maternal under- and overnutrition during pregnancy predispose the offspring to later development of obesity and type 2 diabetes mellitus. A careful examination of the systems concerned with the regulation of food intake, and the neurosubstances involved in such regulation, reveals some of the mechanisms by which maternal nutritional status can affect the offspring and their food-related behaviors.

The discovery of the endocannabinoid signalling system, that is, of cannabinoid receptors, their endogenous ligands, known as endocannabinoids, and of endocannabinoid anabolic and catabolic enzymes, raised several questions regarding the physiopathological role of these mediators. Several of these questions were answered by investigating alterations in the levels of the most studied endocannabinoids, anandamide (AEA) and 2-arachidonoylglycerol (2-AG), in tissues of animal models of disorders, and in bioptic samples and biological fluids (cerebrospinal fluid and blood) of human volunteers. Subsequently, the pharmacological effects of synthetic compounds that selectively target the cannabinoid CB(1) and CB(2) receptors, and endocannabinoid anabolic and catabolic enzymes, established cause-effect relationships between pathological alterations in endocannabinoid levels and the symptoms and progress of several disorders, including emesis, obesity, metabolic disorders, hepatic diseases, pain, inflammation and neurological and neuropsychiatric disorders. These new developments are discussed in this second review on the endocannabinoids, together with the results of pre-clinical and clinical studies on the potential therapeutic use of plant-derived cannabinoids and synthetic agents that manipulate pharmacologically the action at cannabinoid receptors or the tissue levels of AEA and 2-AG.

There is only limited community-based practice safety information available regarding antidepressant use in pediatric patients. This study identifies the factors associated with incident neuroendocrine-related metabolic, digestive, and sexual/reproductive adverse events in children and adolescents treated with antidepressants. A retrospective cohort design evaluating Medicaid medical and pharmacy claims between January, 1996 and December, 2005 was employed for 11970 children and adolescents prescribed an antidepressant medication, and a random sample of 4500 children not treated with psychotropic medications. Incident obesity/weight gain, Type 2 diabetes mellitus, and dyslipidemia were more likely for those prescribed selective serotonin reuptake inhibitors (SSRIs) (OR = 1.49; 1.37; 1.44), whereas Type 2 diabetes mellitus and dyslipidemia were more likely for those prescribed weight-inducing antidepressants (ORs = 1.26; 1.24), and those with pre-existing endocrinopathies (ORs = 3.96; 1.90), controlling for the effects of co-prescribed mood stabilizers or antipsychotics. Incident nausea/vomiting was less likely for those taking SSRIs (OR = 0.78). Females and children under 12 years of age were more likely to develop these adverse effects. Practitioners need to carefully consider the neuroendocrine- related adverse effects of SSRI antidepressant agents in particular, especially in individuals with comorbid endocrine conditions, and those co-prescribed other classes of psychotropic medications.

A temporary non-surgical approach for treatment of obesity is the gastric balloon that serves as an alternative procedure for many patients with frustrated diet attempts. Deflation and displacement of the balloon resulting in acute intestinal obstruction and subsequent surgical intervention is a rare complication. A BioEnterics Intragastric Balloon was endoscopically implanted in a 35-year-old female with a body mass index (BMI) of 28 kg/m(2). The procedure succeeded without complications, and weight loss was effective during the first 6 months. One year after balloon implantation, the patient presented with abdominal cramps and vomiting due to ileal obstruction. Since endoscopic efforts to remove the deflated and displaced balloon failed, emergency laparotomy and enterotomy were necessary. Vascularization of the dilated small bowel was compromised, but recovered after decompression. Patients' postoperative course was uneventful. The gastric balloon model can be associated with major complications and should be used critically. Removal of the balloon should be assured not later than 6 months when weight loss decreases.

Omental torsion is an underdiagnosed cause of abdominal pain in children. It resembles appendicitis, and the diagnosis is often made surgically. We review the presentation, treatment, and outcomes in the largest reported series to date. We recorded demographics, diagnostics, treatment, and histopathology in 18 children with omental torsion between May 2000 and 2007. We found a 4:1 male to female ratio and 85 per cent met criteria for obesity based on Centers for Disease Control and Prevention body mass index-for-age growth chart calculations. Fourteen of 18 (78%) presented with right lower quadrant pain concerning for appendicitis and seven of 18 (39%) with fever, nausea, or vomiting. Mild leukocytosis was found in 78 per cent of patients. All but one was taken to surgery with a diagnosis of appendicitis. Partial omentectomy, either open (50%) or laparoscopic (50%), was performed in all cases. The appendix, resected in 17 patients, was grossly normal. However, 30 per cent of specimens had histopathologic findings of appendicitis. Hospital discharge, after symptom resolution, averaged 33 hours. Surgeons should have a high index of suspicion for omental torsion when evaluating obese children for right lower quadrant pain. Both surgical approaches provide the diagnosis and treatment with minimal morbidity and rapid recovery. We advocate simultaneous appendectomy because appendicitis is often encountered with the torsion.

Practical strategies are available for primary care physicians to monitor psychiatric and medical outcomes as well as treatment adherence in patients with bipolar disorder. Current depressive symptoms can be assessed with tools like the 9-item Patient Health Questionnaire or Beck Depression Inventory. Lifetime presence or absence of manic or hypomanic symptoms can be assessed using the Mood Disorder Questionnaire (MDQ). These measures can be completed quickly by patients prior to appointments. Sensitivity of such ratings, particularly the MDQ, can be increased by having a significant other also rate the patient. Clinicians should also screen mood disorder patients for psychiatric comorbidities that are common in this population such as anxiety and substance use disorders. While patients with bipolar disorder may commonly be nonadherent with prescribed medication regimens, strategies that can help include having frank discussions with the patient, selecting medication collaboratively, adding psychotherapy with a psychoeducation element, monitoring appointment-keeping, using patient self-reports of medication-taking, enlisting the aid of significant others, and measuring plasma drug levels. Medical monitoring is needed to assess the safety and tolerability of psychotropic medications. All of the approved medications for bipolar disorder have at least 1 boxed warning for serious side effects, but are also associated with other common management-limiting side effects such as sedation, tremor, unsteadiness, restlessness, nausea, vomiting, diarrhea, constipation, weight gain, and metabolic problems. Routine monitoring is particularly needed for obesity, metabolic syndrome, and cardiovascular disorders, which lead to high rates of medical morbidity and mortality in patients with bipolar disorder. Monitoring protocols such as the one recommended by the American Diabetes Association for patients taking second-generation antipsychotics can be used for regular assessment.

The objective of this study was to determine whether obesity prevalence and weight-related behaviors (e.g., diet, physical activity) differ among students enrolled in 2-year community/technical colleges and those attending 4-year colleges/universities. This information could inform the development of intervention strategies. Through an existing surveillance system of Minnesota postsecondary education institutions, survey data were collected from 16,539 students from 27 campuses (14 two-year college campuses, 13 four-year college/university campuses; 2007-2008), including self-reported physical activity, media use, dietary patterns, weight control behaviors, height, and weight. Unadjusted analyses indicated that students enrolled in 2-year colleges, particularly females, had a higher prevalence of overweight/obesity, lower levels of physical activity, more television viewing, higher intakes of soda, fast food, and diet pills compared to students attending 4-year colleges (P < 0.05). Females attending 4-year colleges were more likely to engage in certain unhealthy weight control behaviors (taking diet pills, binge eating, self-induced vomiting) compared to females attending 2-year institutions. Among male students there were fewer differences between 2-year and 4-year colleges. Controlling for sociodemographic factors (e.g., race/ethnicity, age), most disparities in prevalence estimates remained, though many were attenuated. Overall, few young adults engage in weight-related behaviors consistent with national recommendations. Two-year college students may represent a particularly at-risk group. Disparities between 2- and 4-year college students exist beyond the sociodemographic differences in these populations. Effective weight-related interventions are needed for young adults, particularly females attending 2-year colleges and all males attending postsecondary institutions.
