Chronic vomiting of unclear etiology has been given a number of names over time. For many years, it was known as "psychogenic" vomiting because a psychiatric etiology was considered the most likely cause. More recently, the concepts of cyclic vomiting syndrome (CVS) and functional vomiting (FV) have been proposed to better explain this perplexing phenomenon. CVS is a dramatic clinical syndrome characterized by intense episodes of vomiting lasting over a period of days but alternating with periods of intense quiescence. FV, as defined by the Rome II diagnostic criteria, is vomiting of at least 3 months, which need not be consecutive, in the preceding year with at least three separate vomiting episodes in a week. It is found in the absence of obvious metabolic, structural, or psychiatric disorders which could explain the vomiting (Table 1). It will be the purpose of this article to review the history of chronic vomiting from a nomenclature perspective. Methodologic limitations of early studies will be described as well as more contemporary reviews that used updated methodologic approaches to describe this perplexing problem.

“…The hindbrain contains the essential motor circuit for producing the emetic reflex (Miller et al, 1994b; Smith et al, 2002), and four neural pathways are known to project to this circuit (Horn, 2008; Horn, 2014): (1) vagal afferents from the gastrointestinal tract, sensitive to mechanical and chemical perturbations, e.g., food poisoning (Hu et al, 2007); (2) input to the VeN from the middle ear, e.g., motion sickness (Yates et al, 1998); (3) AP, an area with a low blood-brain barrier, sensitive to circulating toxins (Miller et al, 1994a); and (4) descending input from the forebrain, potentially responsible for psychogenic or learned emetic responses (Muraoka et al, 1990; Roscoe et al, 2011). An additional possibility, arguably not “normal” sensory activation of of the emetic circuit, would be stimulus actions on the internal components of the emetic system.…”

Role of the abdominal vagus and hindbrain in inhalational anesthesia-induced vomiting

The incidence of postoperative nausea and vomiting (PONV) can be as high as 80% in patients with risk factors (e.g., females, history of motion sickness). PONV delays postoperative recovery and costs several hundred million dollars annually. Cell-based assays show that halogenated ethers (e.g., isoflurane) activate 5-HT3 receptors, which are found on gastrointestinal vagal afferents and in the hindbrain - key pathways for producing nausea and vomiting. This project evaluated the role of the vagus and activation of the hindbrain in isoflurane-induced emesis in musk shrews – a small animal model with a vomiting reflex, which is lacking in rats and mice. Sham-operated and abdominal vagotomized shrews were exposed to 1 to 3% isoflurane to determine effects on emesis; vagotomy was confirmed by lack of vagal transport of the neuronal tracer Fluoro-Gold. In an additional study, shrews were exposed to isoflurane and hindbrain c-Fos was measured at 90 min after exposure using immunohistochemistry. There were no statistically significant effects of vagotomy on isoflurane-induced emesis compared to sham-operated controls. Isoflurane exposure produced a significant increase in c-Fos-positive cells in the nucleus of the solitary tract and vestibular nuclei but not in the area postrema or dorsal motor nucleus. These results indicate that the abdominal vagus plays no role in isoflurane-induced emesis and suggest that isoflurane activates emesis by action on the hindbrain, as shown by c-Fos labeling. Ultimately, knowledge of the mechanisms of inhalational anesthesia-induced PONV could lead to more targeted therapies to control PONV.

“…In one study, 72% TB patients had severe/moderate level of anxiety and depression according to Hospital Anxiety and Depression Scale (HADS) and 22% TB patients with co-morbid anxiety and depression showed multi drug-resistance (15). In another, it is mentioned that habitual postprandial and irregular vomiting is mostly related to major depression (16). Therefore, significant improvement in the patient's general condition under the anti-depressant treatment established the diagnosis.…”

Psychogenic Vomiting Considered as Co-Morbidity With Tuberculosis in Adolescents

A twelve-year-old girl with disseminated Tuberculosis was complicated by psychogenic vomiting and multiple drugs' adverse effects. She was admitted to our hospital, complaining of fever, cough and abdominal pain. Diagnosis of TB was obtained by abdominal CT-scan and open liver biopsy. During the anti-TB treatment, hepatitis, hemolytic anemia and pancreatitis occurred due to some drugs' side effects In addition, her main complaint was of persistent nausea which made all probable somatic basis ruled out, since she did not also show response to routine antiemetic treatment. As a result, the patient's depression as well as the appropriate response to anti-depressant therapy helped us in confirming the diagnosis of psychogenic vomiting.
