Abstract
In recent years, the legalization and social acceptability of cannabis use have increased in the United States. Concurrently, the prevalence of cannabis use has continued to rise, and cannabis products have diversified. There are growing concerns regarding the health effects of regular and high-potency cannabis use, and new research has shed light on its potentially negative effects. Here, we review evidence of the gastrointestinal (GI) effects of cannabis and cannabinoids. Dysregulation of the endocannabinoid system might contribute to various GI disorders, including irritable bowel syndrome and cyclic vomiting syndrome, and endocannabinoids have been found to regulate visceral sensation, nausea, vomiting, and the gut microbiome. Cannabis has been shown to have antiemetic properties, and the US Food and Drug Administration has approved cannabis-based medications for treating chemotherapy-induced nausea and vomiting. Yet, chronic heavy cannabis use has been linked to recurrent episodes of severe nausea and intractable vomiting (cannabinoid hyperemesis syndrome). Given the considerable heterogeneity in the scientific literature, it is unclear if cannabinoid hyperemesis syndrome is truly a distinct entity or a subtype of cyclic vomiting that is unmasked by heavy cannabis use and the associated dysregulation of the endocannabinoid system. The changes in cannabis legalization, availability, and public risk perceptions have outpaced research in this area and there is a need for robust, prospective, large-scale studies to understand the effects of cannabis use on GI health.

Abstract
BACKGROUND Amitriptyline (AT) is recommended as first-line prophylactic therapy in patients with cyclic vomiting syndrome (CVS). However, significant side effects limit its use and dosing is based on trial and error. Though the Clinical Pharmacogenetic Implementation Consortium (CPIC) Guidelines recommend dosing for AT based on CY2D6 and CYP2C19 genotype profile, this is not followed in clinical practice. METHODS This pilot study determined CYP2C19 and CYP2D6 genotypes and ascertained its association with adverse drug reactions (ADRs), clinical response, and serum concentration of AT and nortriptyline in a well-characterized cohort of adults with CVS. KEY RESULTS Of 46 subjects with CVS, age 33 ± 12 years, 61% female, 85% Caucasian, a third (33%) had normal CYP2C19 metabolizer status, while 4% were poor, and 43% were ultrarapid metabolizers. Most (61%) had normal CYP2D6 genotype while 9% were poor and 2% were ultra-rapid metabolizers. There was no statistically significant association between genotype and ADRs, clinical response or serum drug concentration. There was a trend towards significance between genotype and clinical response, with 64% of responders having normal CYP2D6 metabolism versus 36% of nonresponders (p = 0.06). ADRs were encountered in 46% of patients with 28% discontinuing the medication as a result. CONCLUSIONS AND INFERENCES A subset of patients with CVS have dysfunctional alleles of CYP2C19 and CYP2D6. Larger prospective studies to evaluate the clinical impact of pharmacogenomic testing in CVS are needed. This has the potential to optimize clinical management, predict ADRs and allow for personalized therapy.

Abstract
OBJECTIVES Cannabinoid hyperemesis syndrome (CHS) is a clinical condition of cyclic vomiting, nausea, and abdominal pain associated with chronic cannabis use. Despite increased recognition of CHS, there are limited details on cannabis use practices and symptoms over time. Understanding what happens in the period surrounding the ED visit, including any changes in symptoms and cannabis use practices following the visit, can help inform the development of patient-centered interventions around cannabis use disorder for patients with CHS. METHODS A prospective observational cohort (n=39) of patients with suspected CHS recruited from the Emergency Department (ED) at the time of a symptomatic cyclic vomiting episode was followed for three months. Disease progression, cannabis use practices, and health care utilization were monitored. RESULTS Participants reported high rates of persistent CHS symptoms (abdominal pain, nausea, or cyclic vomiting) in the two-week period immediately following an ED visit with a median duration of 7 days. Cannabis use frequency and quantity were reduced immediately after the ED visit, but most participants returned to pre-ED visit cannabis use patterns within a few days. Recurrent ED visits for cyclic vomiting were reported by 25% of participants who completed follow-up during the three month follow up period. CONCLUSIONS Participants continued to have ongoing symptoms after the ED visit, but most manage symptoms on their own and do not return to the ED. Longitudinal studies beyond three months are needed to better understand the clinical course of patients with suspected CHS.

Abstract
Jansen-de Vries syndrome (JdVS) is a neurodevelopmental condition attributed to pathogenic variants in Exons 5 and 6 of PPM1D. As the full phenotypic spectrum and natural history remain to be defined, we describe a large cohort of children and adults with JdVS. This is a retrospective cohort study of 37 individuals from 34 families with disease-causing variants in PPM1D leading to JdVS. Clinical data were provided by treating physicians and/or families. Of the 37 individuals, 27 were male and 10 female, with median age 8.75 years (range 8 months to 62 years). Four families document autosomal dominant transmission, and 32/34 probands were diagnosed via exome sequencing. The facial gestalt, including a broad forehead and broad mouth with a thin and tented upper lip, was most recognizable between 18 and 48 months of age. Common manifestations included global developmental delay (35/36, 97%), hypotonia (25/34, 74%), short stature (14/33, 42%), constipation (22/31, 71%), and cyclic vomiting (6/35, 17%). Distinctive personality traits include a hypersocial affect (21/31, 68%) and moderate-to-severe anxiety (18/28, 64%). In conclusion, JdVS is a clinically recognizable neurodevelopmental syndrome with a characteristic personality and distinctive facial features. The association of pathogenic variants in PPM1D with cyclic vomiting bears not only medical attention but also further pathogenic and mechanistic evaluation.

Abstract
INTRODUCTION Reddit hosts a large active community of members dedicated to the discussion of cannabinoid hyperemesis syndrome. We sought to describe common themes discussed and the most frequently mentioned triggers and therapies for cannabinoid hyperemesis syndrome exacerbations in the Reddit online community. METHODS Data collected from six subreddits were filtered using natural language processing to curate posts referencing cannabinoid hyperemesis syndrome. Based on a manual review of posts, common themes were identified. A machine learning model was trained using the manually categorized data to automatically classify the themes for the rest of the posts so that their distributions could be quantified. RESULTS From August 2018 to November 2022, 2683 unique posts were collected. Thematic analysis resulted in five overall themes: cannabinoid hyperemesis syndrome-related science; symptom timing; cannabinoid hyperemesis syndrome treatment and prevention; cannabinoid hyperemesis syndrome diagnosis and education; and health impacts. Additionally, 447 trigger and 664 therapy-related posts were identified. The most commonly mentioned triggers for cannabinoid hyperemesis syndrome episodes included: food and drink (n = 62), cannabinoids (n = 45), mental health (e.g., stress, anxiety) (n = 27), and alcohol (n = 22). Most commonly mentioned cannabinoid hyperemesis syndrome therapies included: hot water/bathing (n = 62), hydration (n = 60), antiemetics (n = 42), food and drink (n = 38), gastrointestinal medications (n = 38), behavioral therapies (e.g., meditation, yoga) (n = 35), and capsaicin (n = 29). DISCUSSION Reddit posts for cannabinoid hyperemesis syndrome provide a valuable source of community discussion and individual reports of people experiencing cannabinoid hyperemesis syndrome. Mental health and alcohol were frequently reported triggers within the posts but are not often identified in the literature. While many of the therapies mentioned are well documented, behavioral responses such as meditation and yoga have not been explored by the scientific literature. CONCLUSIONS Knowledge shared via online social media platforms contains detailed information on self-reported cannabinoid hyperemesis syndrome disease and management experiences, which could serve as valuable data for the development of treatment strategies. Further longitudinal studies in patients with cannabinoid hyperemesis syndrome are needed to corroborate these findings.

Abstract
BACKGROUND Aprepitant is a neurokinin-1 receptor antagonist, and recent guidelines by the American Neurogastoenterology and Motility Society recommend its use as prophylaxis in moderate-to severe cyclic vomiting syndrome (CVS). Data are limited to small studies in children. We aimed to determine its efficacy in adults with CVS. METHODS A retrospective review of CVS patients diagnosed using Rome criteria at a tertiary referral center was conducted. Drug response was defined as >50% reduction in symptoms and/or healthcare utilization. An intent-to-treat (ITT) analysis was conducted. KEY RESULTS Of 96 patients prescribed aprepitant, 26 (27%) were unable to start due to cost/lack of insurance coverage. Of 70 receiving therapy, mean age was 33 ± 11 years; 51 (73%) were female and 56 (80%) Caucasian. The majority (93%) were refractory to other prophylactic medications. Aprepitant was taken thrice weekly in 51 (73%), daily in 16 (23%) and a few times a month in 3 (4%) due to cost. Fifty (71.4%) had a global symptom response to aprepitant. There was significant reduction in the number of CVS episodes (14.5 ± 11.7 to 6.2 ± 8.0, p < 0.0001), emergency department visits (4.2 ± 7.7 to 1.8 ± 3.4, p = 0.006), and hospital admissions (1.6 ± 3.9 to 0.8 ± 2.1, p = 0.02) in patients treated with aprepitant. Seven (10%) discontinued the drug due to minor side effects. CONCLUSIONS AND INFERENCES Aprepitant is a safe and effective prophylactic medication in adults with refractory CVS. Adequate insurance coverage is a major barrier preventing its use.

Abstract
BACKGROUND Cyclic vomiting syndrome (CVS) is a disorder of gut-brain interaction (DGBI) characterized by recurrent episodes of nausea and vomiting. Most children outgrow their CVS symptoms and develop migraine headaches, but there are limited data in adults. We thus sought to determine the natural history of CVS in adults. METHODS We conducted a retrospective analysis of patients at a specialized tertiary care clinic. Frequency of CVS episodes, emergency department (ED) visits, and hospitalizations were recorded at the index visit and at follow-up. KEY RESULTS Of 455 CVS patients with complete data, mean age was 33 ± 13 years, 294 (65%) were female, and 392 (86%) were Caucasian. Mean duration of follow-up was 47.4 ± 37.2 months. There was a significant reduction in frequency of CVS episodes/year (18 to 6.8), ED visits (6.1 to 2), and hospitalizations (2.3 to 0.7) (all p-values < 0.001) but only 88 (19%) of patients had complete resolution of episodes at follow-up. On multivariable regression analysis, non-white race [0.33 (0.11-0.98) p = 0.01], comorbidity count [0.77 (0.62-0.95) p = 0.01], cannabis use [0.36 (0.2-0.65) p = 0.0007], and aprepitant use [0.2 (0.08-0.005) p < 0.001] were associated with a reduced odds of complete resolution of CVS episodes. Of note, 19 patients (4%) died. CONCLUSIONS AND INFERENCES While most adults with CVS improved with specialized care, in contrast to children, only a small subset (~1 in 5) had complete resolution of symptoms. Reasons for the effects of race, cannabis use, and comorbidity burden on outcomes in CVS are unclear and warrant further investigation.

Abstract
INTRODUCTION Cyclic vomiting syndrome is a chronic debilitating disorder of the gut-brain interaction and is characterized by recurrent episodes of nausea and vomiting.Recent studies indicate that it is common and affects 2% of the US population. Unfortunately, there is significant heterogeneity in the management of these patients in the medical community. This review article aims to bridge this gap and will review the epidemiology and etiology with a focus on management of CVS. AREAS COVERED This article reviews the epidemiology, and pathophysiology of CVS and impact on patients. It also discusses management based on recent guidelines based on which is intended for the busy clinician. A literature search was done using PubMed and key words "cyclic vomiting", "management", "etiology", and pathophysiology were used to identify articles of importance. EXPERT OPINION CVS is a complex, poorly understood disorder of gut-brain interaction (DGBI) and has a significant negative impact on patients, families and the healthcare system. Recent guidelines recommend a multidisciplinary approach to management using prophylactic therapy in moderate-severe CVS and abortive medication for acute flares. However more research is needed to better understand the pathophysiology and develop targeted therapies for CVS.

Abstract
Charles Darwin, the famous naturalist, suffered relapsing, debilitating illness for most of his adult life with a plethora of symptoms. The diagnosis favoured here for this illness is that of an adult-onset mitochondrial disorder due to a maternally inherited, pathological mitochondrial DNA mutation clinically manifesting as MELAS (mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes) syndrome. This diagnosis accounts for Darwin's primary symptoms; in addition, it accounts for the various unusual illnesses that afflicted his siblings and maternal (Wedgwood) ancestors. Symptoms of Darwin's illness may be related to dysfunction of cells with high energy requirements; this includes cells constituting the cardiac conduction system, cerebral endothelial cells, neurons, neuroepithelial cells of the vestibular apparatus, and, as proposed here, central and peripheral neuroendocrine cells. Although Darwin's episodes of sudden facial flushing, his nocturnal panic attacks, and his severe gastrointestinal symptoms are not readily explained, these symptoms may relate to neuroendocrine dysfunction, either an uncontrolled release of stimulatory hormone or impaired inhibitory control. It is also conceivable that the autonomic system had been involved. A study of Darwin's illness may benefit those who suffer from similar symptoms today.

Abstract
BACKGROUND Cyclic vomiting syndrome (CVS) is associated with psychosocial comorbidity and often triggered by stress. Since the current disease-centered care model does not address psychosocial factors, we hypothesized that holistic, patient-centered care integrating meditation and addressing psychosocial needs through a care coordinator will improve healthcare outcomes in CVS. METHODS We conducted a prospective randomized controlled trial: 49 patients with CVS (mean age: 34 ± 14 years; 81% female) were randomized to conventional health care (controls) or Integrative Health care (IHC) (27: controls, 22: IHC). The IHC group was assigned a care coordinator and received meditation with a certified instructor. Outcomes including psychological distress, coping strategies to manage chronic stress, cognitive symptom management, and Health-Related Quality of Life (HRQoL) were measured. KEY RESULTS In intention-to-treat analyses, patients receiving IHC showed significant improvement in multiple domains of coping including positive reframing, planning, and reduction in self-blame (p values ≤0.05), and physical HRQoL (p = 0.03) at 6 months. They also leaned toward spirituality/religion as a coping measure (p ≤ 0.02 at 3 and 6 months). Subgroup analysis of compliant patients showed additional benefit with significant reduction in psychological distress (p = 0.04), improvement in sleep quality (p = 0.03), reduction in stress levels (0.02), improvement in physical HRQoL (0.04), and further improvement in other domains of coping (p < 0.05). CONCLUSIONS AND INFERENCES An IHC model incorporating meditation and care coordination improves patient outcomes in CVS and is a useful adjunct to standard treatment. Studies to determine the independent effects of meditation and care coordination are warranted.

Abstract
OBJECTIVES To synthesize quantitative and qualitative data on pharmacologic interventions of pediatric cyclic vomiting syndrome and their effectiveness in disease management in the acute care setting. STUDY DESIGN Using keywords, 799 studies published up from December 1954 to February 2018 were extracted from MEDLINE via Pubmed, Embase via OVID, CINAHL via EBSCO, and Cochrane Controlled Trials Registry. Studies were evaluated for inclusion and exclusion by 2 independent reviewers using predetermined inclusion and exclusion criteria. RESULTS The search yielded 84 studies for full review, of which 54 were included in the systematic review. Studies were subsequently separated into 1 group of 6 case series studies containing quantitative data on sumatriptan, ondansetron, phenothiazines, prokinetic agents, carbohydrate, isometheptene, and aprepitant; 1 one group consisting only of qualitative studies containing expert recommendations. CONCLUSIONS Ondansetron has the most quantitative and qualitative evidence to support its inclusion in pediatric emergency department protocols as a rescue therapy. Sumatriptan and aprepitant are potential candidates for inclusion as abortive therapies. Qualitative data from retrospective studies and case reports are not applicable to a larger patient population. This report informs a need for controlled, prospective cohort studies and randomized, controlled trials to optimize current management protocols and to develop new medical interventions.

Abstract
Cannabis is commonly used in cyclic vomiting syndrome (CVS) due to its antiemetic and anxiolytic properties. Paradoxically, chronic cannabis use in the context of cyclic vomiting has led to the recognition of a putative new disorder called cannabinoid hyperemesis syndrome (CHS). Since its first description in 2004, numerous case series and case reports have emerged describing this phenomenon. Although not pathognomonic, a patient behavior called "compulsive hot water bathing" has been associated with CHS. There is considerable controversy about how CHS is defined. Most of the data remain heterogenous with limited follow-up, making it difficult to ascertain whether chronic cannabis use is causal, merely a clinical association with CVS, or unmasks or triggers symptoms in patients inherently predisposed to develop CVS. This article will discuss the role of cannabis in the regulation of nausea and vomiting, specifically focusing on both CVS and CHS, in order to address controversies in this context. To this objective, we have collated and analyzed published case series and case reports on CHS in order to determine the number of reported cases that meet current Rome IV criteria for CHS. We have also identified limitations in the existing diagnostic framework and propose revised criteria to diagnose CHS. Future research in this area should improve our understanding of the role of cannabis use in cyclic vomiting and help us better understand and manage this disorder.

Abstract
BACKGROUND This evidence review was conducted to inform the accompanying clinical practice guideline on the management of cyclic vomiting syndrome (CVS) in adults. METHODS We followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework and focused on interventions aimed at prophylactic management and abortive treatment of adults with CVS. Specifically, this evidence review addresses the following clinical questions: (a) Should the following pharmacologic agents be used for prophylaxis of CVS: amitriptyline, topiramate, aprepitant, zonisamide/levetiracetam, or mitochondrial supplements? (b) Should the following pharmacologic agents be used for abortive treatment: triptans or aprepitant? RESULTS We found very low-quality evidence to support the use of the following agents for prophylactic and abortive treatment of CVS: amitriptyline, topiramate, aprepitant, zonisamide/levetiracetam, and mitochondrial supplements. We have moderate certainty of evidence for the use of triptans as abortive therapy. We found limited evidence to support the use of ondansetron and the treatment of co-morbid conditions and complementary therapies. CONCLUSIONS This evidence review helps inform the accompanying guideline for the management of adults with CVS which is aimed at helping clinicians, patients, and policymakers, and should improve patient outcomes.

Abstract
Cyclic vomiting syndrome (CVS) is characterized by severe episodic emesis in adults and children. Cannabinoid hyperemesis syndrome is an increasingly recognized CVS-like illness that has been associated with chronic cannabis use. There are significant gaps in our understanding of the pathophysiology, clinical features, comorbidities, and effective management options of CVS. Recommendations for treating CVS are based on limited clinical data, as no placebo-controlled, randomized trials have yet been conducted. Diseases associated with CVS, including migraine, mitochondrial disorders, autonomic dysfunction, and psychiatric comorbidities, provide clues about pathophysiologic mechanisms and suggest potential therapies. We review our current understanding of CVS and propose future research directions with the aim of developing effective therapy. Establishing a multicenter, standardized registry of CVS patients could drive research on multiple fronts including developing CVS-specific outcome measures to broaden our understanding of clinical profiles, to serve as treatment end points in clinical trials, and to provide a platform for patient recruitment for randomized clinical trials. Such a robust database would also facilitate conduct of research that aims to determine the underlying pathophysiological mechanisms and genetic basis for CVS, as well as identifying potential biomarkers for the disorder. Soliciting government and industry support is crucial to establishing the necessary infrastructure and achieving these goals. Patient advocacy groups such as the Cyclic Vomiting Syndrome Association (CVSA), which partner with clinicians and researchers to disseminate new information, to promote ongoing interactions between patients, their families, clinicians, investigators, to support ongoing CVS research and education, must be an integral part of this endeavor.

Abstract
The increasing recognition of cyclic vomiting syndrome (CVS) in adults prompted the development of these evidence-based guidelines on the management of CVS in adults, which was sponsored by the American Neurogastroenterology and Motility Society (ANMS) and the Cyclic Vomiting Syndrome Association (CVSA). GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework was used and a professional librarian performed the literature search. The expert committee included the President of the CVSA who brought a patient perspective into the deliberations. The committee makes recommendations for the prophylaxis of CVS, treatment of acute attacks, diagnosis, and overall management of CVS. The committee strongly recommends that adults with moderate-to-severe CVS receive a tricyclic antidepressant (TCA), such as amitriptyline, as a first-line prophylactic medication and receive topiramate or aprepitant as alternate prophylactic medications. Zonisamide or levetiracetam and mitochondrial supplements (Coenzyme Q10, L-carnitine, and riboflavin) are conditionally recommended as alternate prophylactic medications, either alone or concurrently with other prophylactic medications. For acute attacks, the committee conditionally recommends using serotonin antagonists, such as ondansetron, and/or triptans, such as sumatriptan or aprepitant to abort symptoms. Emergency department treatment is best achieved with the use of an individualized treatment protocol and shared with the care team (example provided). The committee recommended screening and treatment for comorbid conditions such as anxiety, depression, migraine headache, autonomic dysfunction, sleep disorders, and substance use with referral to appropriate allied health services as indicated. Techniques like meditation, relaxation, and biofeedback may be offered as complementary therapy to improve overall well-being and patient care outcomes.

Abstract
A 14-year-old girl with a history of complex congenital heart disease in end-stage heart failure and with cyclic vomiting was admitted to our hospice program in 2012. Before hospice enrollment, she had required intermittent infusions of dexmedetomidine to abort cyclic vomiting episodes after cardiac catheterization procedures. Following a hospital admission in November 2013, she was discharged home in the care of our hospice on a continuous dexmedetomidine infusion. She remained on this infusion at varying doses (range of 0.1-0.38 mcg/kg/hour) for nearly three years, until her death in September 2016. This report describes the palliative use of dexmedetomidine in this patient and difficulties related to the use of this medication during the course of her care.

Abstract
OBJECTIVES Cannabis hyperemesis syndrome is characterized by bouts of protracted vomiting in regular users of cannabis. We wondered whether this poorly understood condition is idiosyncratic, like motion sickness or hyperemesis gravidarum, or the predictable dose-response effect of prolonged heavy use. METHODS Adults with an emergency department visit diagnosed as cannabis hyperemesis syndrome, near-daily use of cannabis for ≥6 months, and ≥2 episodes of severe vomiting in the previous year were age- and sex-matched to two control groups: RU controls (recreational users without vomiting), and ED controls (patients in the emergency department for an unrelated condition). Δ9-Tetrahydrocannabinol (THC), cannabinol (CBN), cannabidiol, and 11-nor-9-carboxy-THC concentrations in scalp hair were compared for subjects with positive urine THC. RESULTS We obtained satisfactory hair samples from 46 subjects with positive urine THC: 16 cases (age 26.8 ± 9.2 years; 69% male), 16 RU controls and 14 ED controls. Hair cannabinoid concentrations were similar between all three groups (e.g. cases THC 220 [median; IQR 100,730] pg/mg hair, RU controls 150 [71,320] and ED controls 270 [120,560]). Only the THC:CBN ratio was different between groups, with a 2.6-fold (95%CI 1.3,5.7) lower age- and sex-adjusted ratio in cases than RU controls. Hair cannabidiol concentrations were often unquantifiably low in all subjects. CONCLUSIONS Similar hair cannabinoid concentrations in recreational users with and without hyperemesis suggest that heavy use is necessary but not sufficient for hyperemesis cannabis. Our results underline the high prevalence of chronic heavy cannabis use in emergency department patients and our limited understanding of this plant's adverse effects.

Abstract
BACKGROUND Cyclic vomiting syndrome (CVS) is often triggered by stress. Patients report high degrees of psychological distress due to CVS, but there is limited data on factors associated with psychological distress. We sought to determine the degree of psychological distress and its correlation with clinical characteristics in CVS. METHODS The Brief Symptom Inventory (BSI), a validated tool to determine psychological distress, was administered prospectively to patients. The control population consisted of 719 normal subjects. Student's t test was used to compare means, and logistic regression analysis was performed to identify predictors of a GSI score ≥63, indicating high degrees of psychological distress. Scores for the regression predictors were calculated using the maximum likelihood estimate for the logistic regression model and was called the DAME score (depression, age 25-35, chronic marijuana use, and interepisodic GI symptoms). KEY RESULTS Of 87 patients, 60% were female, 92% were caucasian, and mean age was 37 years. Forty-one percent of patients had high degrees of psychological distress with the highest scores for somatization. Independent predictors of psychological distress included depression, young age (25-35 years), chronic marijuana use, and interepisodic dyspepsia (called the DAME score). A score of ≥7 accurately predicted psychological distress in >88% of patients. CONCLUSIONS & INFERENCES Psychological distress is common in CVS and can be predicted accurately using our proposed DAME score. Whether psychological distress is a cause or an effect of CVS needs to be determined. Addressing psychological distress can potentially improve overall healthcare outcomes in CVS.

Abstract
Cannabinoid hyperemesis syndrome (CHS) has become more prevalent with increasing cannabis use. CHS is often resistant to standard antiemetics. The objective of this study is to review the current evidence for pharmacologic treatment of CHS. Medline, PsycINFO, DARE, OpenGrey, Google Scholar, and the Cochrane Library were searched from inception to February 2017. Articles were selected and reviewed independently. Evidence was graded using Oxford Center for Evidence-Based Medicine guidelines. The search resulted in 1262 articles with 63 of them eligible for inclusion (205 human subjects). There were 4 prospective level-2, 3 retrospective level-3 studies, 12 level-4 case series, and 44 level-5 case reports. Among level-2 studies (64 subjects), tricyclic antidepressants (TCAs) and lorazepam were discussed as effective long- and short-term treatments, respectively, in two studies. Ondansetron, promethazine, diphenhydramine, and opioids were also mentioned, but the authors did not comment on their efficacy. Among level-3 studies (43 subjects), one reported effective treatment with antiepileptics zonisamide and levetiracetam, but not TCAs. Another reported favorable response to morphine, ondansetron, and lorazepam but did not specify the actual number of patients receiving specific treatment. Among the level-4 case series (54 subjects), benzodiazepines, haloperidol, and capsaicin were reported as helpful. For level-5 case reports (44 subjects), benzodiazepines, metoclopramide, haloperidol, ondansetron, morphine, and capsaicin were reported as effective. Effective treatments mentioned only once included fentanyl, diazepam, promethazine, methadone, nabilone, levomepromazine, piritramide, and pantoprazole. Hot showers and baths were cited in all level-4 and -5 articles as universally effective. High-quality evidence for pharmacologic treatment of CHS is limited. Benzodiazepines, followed by haloperidol and capsaicin, were most frequently reported as effective for acute treatment, and TCAs for long-term treatment. As the prevalence of CHS increases, future prospective trials are greatly needed to evaluate and further define optimal pharmacologic treatment of patients with CHS.

Abstract
The case of a 22 year old woman with cannabinoid hyperemesis syndrome (CHS) presenting as an eating disorder is described. The importance of recognizing chronic cannabis use as a cause of episodic vomiting is emphasized, given that CHS can be confused with self-induced purging and cyclic vomiting. This case was further complicated by the well-defined history of anorexia nervosa (binge-purge type), major depressive disorder, obsessive-compulsive disorder, migraine headache, and the initial denial of cannabis use. However, collateral history and a positive drug screen confirmed the diagnosis. The signs, symptoms and pathophysiological mechanisms of CHS are reviewed in light of clinical presentations that mimic eating disorder phenomenology complicated by addiction. Given the trend for increasing legalization of recreational marijuana as well as medical marijuana, CHS is an important and potentially complicating disorder that eating disorder clinicians need to be aware of. © 2016 Wiley Periodicals, Inc.

Abstract
Bohring-Opitz syndrome is a rare genetic condition characterized by distinctive facial features, variable microcephaly, hypertrichosis, nevus flammeus, severe myopia, unusual posture (flexion at the elbows with ulnar deviation, and flexion of the wrists and metacarpophalangeal joints), severe intellectual disability, and feeding issues. Nine patients with Bohring-Opitz syndrome have been identified as having a mutation in ASXL1. We report on eight previously unpublished patients with Bohring-Opitz syndrome caused by an apparent or confirmed de novo mutation in ASXL1. Of note, two patients developed bilateral Wilms tumors. Somatic mutations in ASXL1 are associated with myeloid malignancies, and these reports emphasize the need for Wilms tumor screening in patients with ASXL1 mutations. We discuss clinical management with a focus on their feeding issues, cyclic vomiting, respiratory infections, insomnia, and tumor predisposition. Many patients are noted to have distinctive personalities (interactive, happy, and curious) and rapid hair growth; features not previously reported.

Abstract
BACKGROUND Charles Darwin (CD), "father of modern biology," suffered from multisystem illness from early adulthood. The most disabling manifestation was cyclic vomiting syndrome (CVS). This study aims at finding the possible cause of CVS in CD. METHODS A literature search using the PubMed database was carried out, and CD's complaints, as reported in his personal writings and those of his relatives, friends, colleagues, biographers, were compared with various manifestations of mitochondrial disorders (MIDs), known to cause CVS, described in the literature. RESULTS Organ tissues involved in CD's disease were brain, nerves, muscles, vestibular apparatus, heart, gut, and skin. Cerebral manifestations included episodic headache, visual disturbance, episodic memory loss, periodic paralysis, hysterical crying, panic attacks, and episodes of depression. Manifestations of polyneuropathy included numbness, paresthesias, increased sweating, temperature sensitivity, and arterial hypotension. Muscular manifestations included periods of exhaustion, easy fatigability, myalgia, and muscle twitching. Cardiac manifestations included episodes of palpitations and chest pain. Gastrointestinal manifestations were CVS, dental problems, abnormal seasickness, eructation, belching, and flatulence. Dermatological manifestations included painful lips, dermatitis, eczema, and facial edema. Treatments with beneficial effects to his complaints were rest, relaxation, heat, and hydrotherapy. CONCLUSION CVS in CD was most likely due to a multisystem, nonsyndromic MID. This diagnosis is based upon the multisystem nature of his disease, the fact that CVS is most frequently the manifestation of a MID, the family history, the variable phenotypic expression between affected family members, the fact that symptoms were triggered by stress, and that only few symptoms could not be explained by a MID.

Abstract
Marijuana is the most widely used recreational drug in the US. Hyperemetic hydrophilic syndrome is a previously described but infrequently recognized condition of cannabinoid abuse with hyperemesis and obsessive hot showering. We present a 47-year-old male known marijuana addict with intractable abdominal pain who could not wait for physical examination, meal, or medication, because of obsessive compulsive warm baths. He had a history of epilepsy and addiction to marijuana, which he took on the day of admission. He presented to the hospital with a seizure, complicated by nausea, vomiting, and severe abdominal pain. His examination was unremarkable, except for mild epigastric tenderness. His laboratory and radiological tests were within normal limits, except for a positive urine drug screen for marijuana and opiates. He took himself immediately to the bathroom and remained under a hot shower with the exception of two 15-minute breaks for the rest of the day. He stated that it made him feel better than medication. Receiving medication and even eating was a problem because of this compulsive showering. Abstinence from marijuana during the hospital stay made the patient’s nausea and vomiting resolve significantly. Cannabinoid hyperemesis is a differential diagnosis among patients with intractable nausea, vomiting, and obsessive hot bathing. The syndrome is an unmistakable indication of marijuana addiction. A thorough history and observation is very valuable. Recognition of this entity will reduce unnecessary testing and utilization of health care resources.
