Normoglycemic diabetic ketoacidosis should be suspected in pregnant women presenting nausea, vomiting, abdominal pain and anorexia. We report a 39 years old woman with a 32 weeks pregnancy who sought emergency care due to hyperemesis. She was hospitalized with the following diagnoses: pregnancy hypertension syndrome, gestational diabetes, morbid obesity and poor prenatal control. The evaluation of the feto-placental unit showed perception of fetal movements, non-reactive non-stress baseline record and a biophysical profile of 6/8. Fetal maturation was initiated. Laboratory tests showed a metabolic acidosis, a low pH, an increased Gap anion, elevated ketonemia and a blood glucose of 172 mg/dl. A diagnosis of normoglycemic diabetic ketoacidosis was formulated and treatment with hydration and regular insulin according to capillary blood glucose levels was started. An emergency caesarean section was performed. The newborn weighed 2.650 kg, had a length of 46 cm, was large for gestational age, had an Apgar score of 2.7, had perinatal asphyxia, convulsive syndrome and a possible congenital cardiopathy. Once the ketoacidosis was resolved during the immediate puerperium, slow acting insulin was initiated.

Cannabis-related ED visits are on the rise due to wider legalization and availability of marijuana, and habitual daily use is increasingly common. Cannabis abuse has long been associated with various short-term and long-term adverse reactions. One such reaction is cannabinoid hyperemesis syndrome: cyclical vomiting, nausea, and abdominal pain that only resolves with a warm bath or shower. Healthcare providers must understand the signs and symptoms of cannabinoid hyperemesis syndrome so the problem can be recognized early and patients avoid unnecessary testing.

Cannabinoid hyperemesis syndrome (CHS), a variant of cyclic vomiting syndrome, is an enigmatic and challenging clinical disorder. As cannabis legalization, use, and potency has increased worldwide over the past decade, so has the prevalence of CHS. These patients often require acute care and inpatient treatment for refractory emesis, electrolyte derangement, dehydration, acute renal failure, and injury to the upper gastrointestinal tract. Routinely-prescribed antiemetics are frequently associated with treatment failure in CHS, necessitating use of sedating agents such as benzodiazepines and antipsychotics. Hydrotherapy with hot water provides short-term symptomatic relief from acute episodes of CHS. The reasons for this may be from chronic and/or excessive cannabis use leading to abnormal stimulation of the hypothalamic-pituitary-adrenal axis (HPA) and sympathetic nervous system (SNS) in CHS patients. Overuse of cannabis may also lead to dysfunction of the endocannabinoid system, which is essential for allostasis of the autonomic nervous system after stress.

Cannabinoid hyperemesis syndrome (CHS) is an underrecognized diagnosis among adolescents. In the adult literature, it is characterized as nausea, vomiting, and abdominal pain in patients with chronic marijuana use. CHS is often refractory to the standard treatment of nausea and vomiting. Unconventional antiemetics, such as haloperidol, have been successful in alleviating symptoms; however, even 1 dose of haloperidol can lead to grave adverse effects, such as dystonia, extrapyramidal reactions, and neuroleptic malignant syndrome. The use of topical capsaicin cream to treat CHS has been well described in the adult literature. This treatment is cost-effective and is associated with few serious side effects. Here, we describe 2 adolescent patients with nausea, vomiting, and abdominal pain in the setting of chronic cannabis use whose symptoms were not relieved by standard antiemetic therapies, but who responded well to topical capsaicin administration in our pediatric emergency department. We also discuss the pathophysiology behind capsaicin's efficacy. These are the first reported cases in which capsaicin was successfully used to treat CHS in pediatric patients.

Cannabinoid hyperemesis syndrome (CHS) is a clinical entity in which marijuana users develop nausea, vomiting, and abdominal pain that improves with hot water bathing or cannabis cessation. Previous models suggest that CHS arises solely from the derangement of cannabinoid receptor type 1 signaling. However, involvement of transient receptor potential vanilloid subtype 1 (TRPV1) receptor, which is activated by marijuana, capsaicin, and heat, could fill gaps in existing models, including the enigmatic role of hot water bathing. We propose that chronic cannabis use decreases TRPV1 signaling and alters gastric motility, and we report the case of a CHS patient whose symptoms improved after topical capsaicin.

Cyclic vomiting syndrome (CVS) is a disorder characterized by episodes of nausea and vomiting lasting for 1-5 days followed by asymptomatic periods. The etiology of CVS is unknown, but it shares similar characteristics to migraine headaches. CVS is generally classified as having four phases: prodromal, acute/vomiting/hyperemesis, recovery, and remission/interepisodic. Current management strategies include trigger avoidance, abortive and prophylactic medication therapies, and supportive care. The goal of therapy for the remission phase is prophylaxis of further episodes. Antidepressant, antiepileptic, and antimigraine medications show an overall reduction or remission of CVS symptoms in more than 70% of patients. This article provides a summary of diagnostic strategies and reviews current management strategies for CVS.

Hyperemesis gravidarum is persistent vomiting, seen more often in the first trimester of pregnancy, when the patient is unable to maintain adequate hydration. Intractable vomiting can lead to severe electrolyte imbalance, which may cause electrocardiogram abnormalities. Occasionally, ventricular tachycardia can complicate a pregnancy. Although its occurrence usually indicates an underlying cardiac structural or arrhythmic abnormality, it may rarely occur in a pregnant patient with structurally normal heart. We report a rare case of ventricular tachycardia, secondary to hyperemesis induced hypomagnesemia and hypokalemia, in a pregnant patient with a structurally normal heart.

Despite current legal and medical controversies surrounding cannabinoids, it is a fact that emergency departments are seeing an increasing number of patients presenting with symptoms associated with the use of these drugs. This review outlines the pathophysiology of cannabinoids, the potential clinical findings associated with their use, and the current evidence for best-practice management of patients who present to the emergency department with signs of acute intoxication and chronic use. Differences between natural and synthetic cannabinoids are discussed, along with the latest evidence for diagnosing and managing patients presenting with the intractable vomiting of cannabinoid hyperemesis syndrome.Emerging treatments for cannabinoid hyperemesis syndrome are presented, including hot water bathing, early haloperidol administration, and topical capsaicin, in addition to an update on the legal status of medical cannabinoid substances.

The adverse effects of marijuana are well documented, as well as its positive therapeutic uses. Cannabis has traditionally been associated with an antiemetic action following acute ingestion and synthetic cannabinoids have an established use as antiemetics for chemotherapy induced nausea. However, there has been limited recognition of chronic cannabis use as a cause of cyclic vomiting syndrome. Cannabinoid hyperemesis was first identified by Allen er al in 2004. Compulsive bathing was also described as part of the clinical picture. This same syndrome has been confirmed a number of times in the medical literature in the interim. The condition has, to our knowledge, never been reported, in a psychiatric patient.
