Response to pharmacologic treatments may identify groups of disorders with a common pathophysiology. The authors applied a treatment-response model, based on four classes of antidepressants (tricyclic types, monoamine oxidase inhibitors, serotonin uptake inhibitors, and atypical agents), to the medical literature. The model identified eight disorders that may share a pathophysiologic abnormality: major depression, bulimia, panic disorder, obsessive-compulsive disorder, attention deficit disorder with hyperactivity, cataplexy, migraine, and irritable bowel syndrome. Phenomenologic and family studies support this grouping. If the model is validated, this family of disorders, which the authors term "affective spectrum disorder," would represent one of the most prevalent diseases in the population.

The highly evolutionarily conserved serotonin transporter (SERT) regulates the entire serotoninergic system and its receptors via modulation of extracellular fluid serotonin concentrations. Differences in SERT expression and function produced by three SERT genes and their variants show associations with multiple human disorders. Screens of DNA from patients with autism, ADHD, bipolar disorder, and Tourette's syndrome have detected signals in the chromosome 17q region where SERT is located. Parallel investigations of SERT knockout mice have uncovered multiple phenotypes that identify SERT as a candidate gene for additional human disorders ranging from irritable bowel syndrome to obesity. Replicated studies have demonstrated that the SERT 5'-flanking region polymorphism SS genotype is associated with poorer therapeutic responses and more frequent serious side effects during treatment with antidepressant SERT antagonists, namely, the serotonin reuptake inhibitors (SRIs).

Convincing healthy people that they are sick and require medicines can enormously expand the market. Disease mongering can turn ordinary ailments like baldness into medical problems, consider risk factors such as hypertension and osteoporosis as diseases and frame prevalence estimates to increase potential markets. In Asia, conditions like erectile dysfunction, male pattern baldness, attention deficit hyperactivity disorder and irritable bowel syndrome, and the drugs to treat them, are widely promoted. Fairness creams and traditional medicines are also widely used. The cost of disease mongering to the individual and the community is expected to be high. Some authors have argued that medicalisation of illnesses may not be a problem and the real problem may be the lack of medicines. Doctors will play a key role in combating disease mongering. Disentanglement from the pharmaceutical industry and development of a capacity for critical analysis are required. Educating patients and empowering them to make decisions are important. Several initiatives have been undertaken to combat disease mongering. Initiatives at the level of the patient and the physician are especially important. Studies on the extent and knowledge of disease mongering among doctors and medical students, and their economic and social consequences are urgently required.

Guanylate cyclase-C (GC-C) is a transmembrane receptor activated by bacterial heat-stable enterotoxins and by the endogenous hormones guanylin and uroguanylin. GC-C plays key roles in the regulation of intestinal fluid and electrolyte homeostasis. This is highlighted by several recently identified human mutations in GUCY2C, the gene encoding GC-C, which leads to the respective gain or loss of function of GC-C, resulting in profound effects on gastrointestinal function. However, a wealth of recent studies indicates GC-C signalling extends to a multitude of diverse additional functions. Recent pre-clinical and clinical studies demonstrate a novel first-in-class GC-C activating peptide, Linaclotide, provides effective relief from constipation and abdominal pain in patients with chronic constipation and constipation-predominant Irritable Bowel Syndrome. Accumulating evidence also suggests GC-C plays protective roles in mucosal barrier function, tissue injury and inflammation, whilst GC-C signalling is a key regulator of intestinal cell proliferation and apoptosis. Finally, recently identified extra-intestinal GC-C signalling pathways make novel contributions to the regulation of food intake and symptoms associated with Attention Deficit Hyperactivity Disorder. Consequently, these findings provide GC-C expression and its associated mutations as potential diagnostic markers for disease. They also provide current and future therapeutic potential for GC-C signalling within and outside the gastrointestinal tract.

Food is essential for life. Yet, poor food choices may cause poor health. Dietary manipulation is frequently integrated into the management of common chronic pediatric conditions. Parents seek dietary information to have more control over child's condition and to avoid side effects of medicine. This article reviews selected diets for a few common pediatric disorders including eczema, attention deficit hyperactivity disorder, headache and migraine, non-celiac gluten sensitivity, and irritable bowel syndrome.

Melatonin is a hormone secreted by the pineal gland at night. This hormone has many physiological functions, the main one being to synchronise individuals' biological rhythms. Exogenous melatonin has the same chronobiotic action, even at small doses (0.125mg). In addition, a sleep-inducing (soporific) action appears to occur in a dose-effect relationship, i.e. as the dose increases. In psychiatric disorders, these two effects could have interesting applications in clinical practice. The French institute of medical research on sleep (SFRMS) appointed a group of experts to conduct a consensus conference to study the indications of melatonin and the conditions of its prescription. An account of the conclusions on adult psychiatric disorders (presented orally at the Congress on Sleep in Marseille, 23 November 2017) is given here. Exogenous melatonin proves to be useful among patients with a stabilized psychiatric disorder or in remission, to prevent relapse in case of associated complaints of insomnia, poor quality sleep or delayed sleep phase syndrome. During acute phases, melatonin could be used as an adjuvant treatment when there are insomnia symptoms, in mood disorders (bipolar disorder, major depressive disorder, seasonal affective disorder), in attention deficit hyperactivity disorder (ADHD), in peri-surgical anxiety and in schizophrenia. In somatoform disorders, melatonin is a possible treatment for painful symptoms in fibromyalgia, irritable bowel syndrome, functional dyspeptic syndrome and temporomandibular joint dysfunction.
