Introduction: Cannabinoid hyperemesis syndrome (CHS) is a paradoxical side effect of cannabis use. Patients with CHS often present multiple times to the Emergency Department (ED) with cyclical nausea, vomiting and abdominal pain, and are discharged with various misdiagnoses. CHS studies to date are limited to case series. We examined the epidemiology of CHS cases presenting to two major urban Tertiary Care Centre EDs. Methods: Using explicit variables, trained abstractors, and standardized abstraction forms, we abstracted data for all adults (18-55 years) with a presenting complaint of vomiting, and/or a discharge diagnosis of vomiting and/or cyclical vomiting, during a 2-year period. Inter-rater agreement was measured using a kappa statistic. Results: We identified 494 cases: mean age 31 years; 36% male; only 19.4% of charts specifically reported cannabis use. Among the regular cannabis users (>3 times per week), 43% had repeat ED visits for similar complaints. Interestingly, of these patients, 92% had bloodwork done in the ED, 92% received IV fluids, 89% received anti-emetics, 27% received opiates, 19% underwent imaging, 8% were admitted to hospital, and 8% were referred to the Gastroentorology service. Inter-rater reliability for data abstraction was kappa = 1. Conclusion: This study suggests CHS may be an overlooked diagnosis for nausea and vomiting, a factor which can possibly contribute to unnecessary investigations and treatment in the ED. Additionally, this indicates a lack of screening for CHS on ED history, especially in quantifying cannabis use and eliciting associated symptoms of CHS.

Introduction: Cannabinoid Hyperemesis Syndrome (CHS) in pediatric patients is poorly characterized. Literature is scarce, making identification and treatment challenging. This study's objective was to describe demographics and visit data of pediatric patients presenting to the emergency department (ED) with suspected CHS, in order to improve understanding of the disorder. Methods: A retrospective chart review was conducted of pediatric patients (12-17 years) with suspected CHS presenting to one of two tertiary-care EDs; one pediatric and one pediatric/adult (combined annual pediatric census 40,550) between April 2014-March 2019. Charts were selected based on discharge diagnosis of abdominal pain or nausea/vomiting with positive cannabis urine screen, or discharge diagnosis of cannabis use, using ICD-10 codes. Patients with confirmed or likely diagnosis of CHS were identified and data including demographics, clinical history, and ED investigations/treatments were recorded by a trained research assistant. Results: 242 patients met criteria for review. 39 were identified as having a confirmed or likely diagnosis of CHS (mean age 16.2, SD 0.85 years with 64% female). 87% were triaged as either CTAS-2 or CTAS-3. 80% of patients had cannabis use frequency/duration documented. Of these, 89% reported at least daily use, the mean consumption was 1.30g/day (SD 1.13g/day), and all reported ≥6 months of heavy use. 69% of patients had at least one psychiatric comorbidity. When presenting to the ED, all had vomiting, 81% had nausea, 81% had abdominal pain, and 30% reported weight loss. Investigations done included venous blood gas (30%), pregnancy test in females (84%), liver enzymes (57%), pelvic or abdominal ultrasound (19%), abdominal X-ray (19%), and CT head (5%). 89% of patients received treatment in the ED with 81% receiving anti-emetics, 68% receiving intravenous (IV) fluids, and 22% receiving analgesics. Normal saline was the most used IV fluid (80%) and ondansetron was the most used anti-emetic (90%). Cannabis was suspected to account for symptoms in 74%, with 31% of these given the formal diagnosis of CHS. 62% of patients had another visit to the ED within 30 days (prior to or post sentinel visit), 59% of these for similar symptoms. Conclusion: This study of pediatric CHS reveals unique findings including a preponderance of female patients, a majority that consume cannabis daily, and weight loss reported in nearly one third. Many received extensive workups and most had multiple clustered visits to the ED.

ABSTRACTBackground:Within the emergency department (ED) patient population there is a subset of patients who make frequent visits. This chart review sought to characterize this population and identify strategies to reduce frequent ED visits.Methods:Frequent use at an urban tertiary care centre was defined as 15 or more visits over 1 year. The details of each visit—demographics, entrance complaint, discharge diagnosis, arrival method, Canadian Triage and Acuity Scale (CTAS) score, and length of stay—were analyzed and compared to data from the entire ED population for the same period.Results:Ninety-two patients generated 2,390 ED visits (of 25,523 patients and 44,204 visits). This population was predominantly male (66%) and middle-aged (median 42 years), with no fixed address (27.2%). Patients arrived by ambulance in 59.3% of visits with less acute CTAS scores than the general population. Substance use accounted for 26.9% of entrance complaints. Increased lengths of stay were associated with female gender and abnormal vital signs, whereas shorter stays were associated with no fixed address and substance use (p< 0.05). Admissions were lower than the general population, and women were twice as likely as men to be admitted (p< 0.05). Patients left without being seen in 15.8% of visits.Conclusions:High-frequency ED users are more likely to be male, younger, and marginally housed and to present secondary to substance use. Although admissions among this population are low, the costs associated with these presentations are high. Interventions designed to decrease visits and improve the health of this population appear warranted.

Background Acquiring a reliable estimate of glomerular filtration rate (eGFR) at the emergency department (ED) is important for clinical management and for dosing renally excreted drugs. However, renal function formulas such as CKD-EPI can give biased results when serum creatinine (SCr) is not in steady-state because the assumption that urinary creatinine excretion is constant is then invalid. We assessed the extent of this by analysing variability in SCr in patients who visited the ED of a tertiary care centre. Methods Data from ED visits at the University Medical Centre Utrecht, the Netherlands between 2012 and 2019 were extracted from the Utrecht Patient Oriented Database. Three measurement time points were defined for each visit: last SCr measurement before visit as baseline (SCr-BL), first measurement during visit (SCr-ED) and a subsequent measurement between 6 and 24 hours during admission (SCr-H1). Non-steady-state SCr was defined as exceeding the Reference Change Value (RCV), with 15% decrease or 18% increase between successive SCr measurements. Exceeding the RCV was deemed as a significant change. Results Of visits where SCr-BL and SCr-ED were measured (N = 47,540), 28.0% showed significant change in SCr. Of 17,928 visits admitted to the hospital with a SCr-H1 after SCr-ED, 27,7% showed significant change. More than half (55%) of the patients with SCr values available at all three timepoints (11,054) showed at least one significant change in SCr over time. Conclusion One third of ED visits preceded and/or followed by creatinine measurement show non-stable serum creatinine concentration. At the ED automatically calculated eGFR should therefore be interpreted with great caution when assessing kidney function.

Abstract Background Cannabinoid Hyperemesis Syndrome (CHS) in paediatric patients is poorly characterized. Identification and treatment of adolescents presenting to the emergency department (ED) for suspected CHS is challenging. Given the paucity of literature on paediatric CHS and the recent legalization of cannabis, it is important to gain a better understanding of this disorder. Objectives The objective of this study was to describe demographics and ED visit data of paediatric patients presenting to the ED with suspected CHS. Design/Methods A retrospective chart review was conducted of paediatric patients (12-17 years) with suspected CHS presenting to one of two tertiary-care EDs; one paediatric (annual census 38,500) and one paediatric and adult (annual census 60,000) between April 2014-March 2019. Charts were selected based on discharge diagnosis of abdominal pain or nausea/vomiting with positive cannabis urine screen, or discharge diagnosis of cannabis use, using ICD-10 codes. Patients with confirmed or likely diagnosis of CHS were identified and data including demographics, clinical history, and ED investigations/treatments were recorded by a trained research assistant. Results A total of 242 patients met criteria for review. Thirty-nine were identified as having a confirmed or likely diagnosis of CHS (mean age 16.2, SD 0.85 years with 64% female), 87% were triaged as either CTAS-2 or CTAS-3 and 80% of patients had cannabis use frequency/duration documented. Of these, 89% reported at least daily use, the mean consumption was 1.30g/day (SD 1.13g/day), and all reported ≥6 months of heavy use. Sixty-nine percent of patients had at least one psychiatric comorbidity. When presenting to the ED, all had vomiting, 81% had nausea, 81% had abdominal pain and 30% reported weight loss. Investigations done included venous blood gas (30%), pregnancy test in females (84%), liver enzymes (57%), pelvic or abdominal ultrasound (19%), abdominal X-ray (19%), and CT head (5%). Eighty-nine percent of patients received treatment in the ED with 81% receiving anti-emetics, 68% receiving intravenous fluids, and 22% receiving analgesics. Normal saline was the most used intravenous fluid (80%) and ondansetron was the most used anti-emetic (90%). Cannabis was suspected to account for symptoms in 74% (with 31% of these given the formal diagnosis of CHS). Sixty-two percent of patients had another visit to the ED within 30 days (59% of these for similar symptoms). Conclusion This study of paediatric CHS reveals unique findings including a preponderance of female patients, a majority that consume cannabis daily, and weight loss reported in nearly 1/3rd. Many received extensive workups and most had multiple clustered visits to the ED.

Background: Peripartum hysterectomy is a life-saving procedure resorted to when conservative measures fail to control obstetric haemorrhage. Several predisposing factors, suboptimal care and lack of infrastructure may lead to this emergency procedure. We wanted to find out factors associated with peripartum hysterectomy and the adverse maternal outcomes at our centre.Methods: A retrospective case series analysis of 40 cases of peripartum hysterectomy performed over a period of 5 years from January 2010 to December 2014 at Government Medical College Hospital, Thrissur, Kerala was done.Results: The incidence of peripartum hysterectomy was 0.29%. The most common indication for peripartum hysterectomy was hysterectomy was uterine atony (50%). Thirty-five women (88%) were between 20 and 35 years. Most of the subjects were unbooked. There were two maternal deaths (case fatality rate of 5%) following peripartum hysterectomy during this period. All the subjects required blood transfusion.Conclusions: Prompt performance hysterectomy before the patient’s clinical condition deteriorates is the key to success. The incidence of adherent placenta is increasing, so every effort should be taken to reduce the caesarean section rates globally.

Background. Chronic cannabis use has become prevalent with decriminalization, medical prescription, and recreational legalization in numerous US states. With this increasing incidence of chronic cannabis use a new clinical syndrome has become apparent in emergency departments and hospitals across the country, termed Cannabinoid Hyperemesis (CH). CH has been described as cyclical vomiting and abdominal pain in the setting of chronic cannabis use, which is often temporarily relieved by hot showers. CH presents a diagnostic challenge to clinicians who do not have a high clinical suspicion for the syndrome and can result in high costs and resource utilization for hospitals and patients. This study investigates the expenditures associated with delayed CH evaluation and delayed diagnosis. Methods. This is a retrospective observational study of 17 patients diagnosed with CH at three medical centers in the United States from 2010 to 2015, consisting of two academic centers and a community hospital. Emergency department (ED) costs were calculated and analyzed for patients eventually diagnosed with CH. Results. For the 17 patients treated, the total cost for combined ED visits and radiologic evaluations was an average of $76,920.92 per patient. On average these patients had 17.9 ED visits before the diagnosis of CH was made. Conclusion. CH provides a diagnostic challenge to clinicians without a high suspicion of the syndrome and may become increasingly prevalent with current trends toward cannabis legalization. The diagnosis of CH can be made primarily through a thorough history and physical examination. Awareness of this syndrome can save institutions money, prevent inappropriate utilization of healthcare resources, and save patients from unnecessary diagnostic tests.

Objectives Radiological balloon dilatation of lower oesophageal strictures is common practice. Other than some early reports from our own centre, there is little published regarding radiological dilatation of pharyngeal and upper oesophageal strictures and less still on radiological balloon dilatation of post-total laryngectomy and pharyngolaryngectomy neo-pharyngeal strictures. Standard practise is bouginage under general anaesthaesia. The objective of this study is to assess the efficacy of radiological balloon dilatation for the treatment of dysphagia secondary to neopharyngeal strictures in patients who have undergone laryngectomy. Methods A tertiary care centre case series of 20 consecutive patients (17 males and 3 females aged 40 to 84) with pharyngeal stricture and dysphagia post-total laryngectomy or pharyngolaryngectomy who underwent balloon dilatation of the stricture under radiological guidance. Maintenance of swallowing was the main outcome measure. Results 5 patients gained relief of their dysphagia with 1 balloon dilatation only. 9 patients required more than 1 dilatation to maintain swallowing. 2 patients had balloon dilatation procedures and stent insertion for palliative relief of dysphagia from known recurrent malignant disease. 3 patients failed to maintain swallowing with repeat dilatations. No patients suffered any significant complications such as perforation. Conclusions Balloon dilatation is minimally invasive and less traumatic than rigid pharyngoscopy with bouginage dilatation. It is well tolerated. It may be repeated frequently and can successfully relieve strictures of the pharynx in patients who have undergone total laryngectomy or pharyngolaryngectomy.

Abstract Background Malaria and HIV are two important public health issues. However, evidence on HIV-Plasmodium vivax co-infection (HIV/PvCo) is scarce, with most of the available information related to Plasmodium falciparum on the African continent. It is unclear whether HIV can change the clinical course of vivax malaria and increase the risk of complications. In this study, a systematic review of HIV/PvCo studies was performed, and recent cases from the Brazilian Amazon were included. Methods Medical records from a tertiary care centre in the Western Brazilian Amazon (2009–2018) were reviewed to identify HIV/PvCo hospitalized patients. Demographic, clinical and laboratory characteristics and outcomes are reported. Also, a systematic review of published studies on HIV/PvCo was conducted. Metadata, number of HIV/PvCo cases, demographic, clinical, and outcome data were extracted. Results A total of 1,048 vivax malaria patients were hospitalized in the 10-year period; 21 (2.0%) were HIV/PvCo cases, of which 9 (42.9%) had AIDS-defining illnesses. This was the first malaria episode in 11 (52.4%) patients. Seven (33.3%) patients were unaware of their HIV status and were diagnosed on hospitalization. Severe malaria was diagnosed in 5 (23.8%) patients. One patient died. The systematic review search provided 17 articles (12 cross-sectional or longitudinal studies and 5 case report studies). A higher prevalence of studies involved cases in African and Asian countries (35.3 and 29.4%, respectively), and the prevalence of reported co-infections ranged from 0.1 to 60%. Conclusion Reports of HIV/PvCo are scarce in the literature, with only a few studies describing clinical and laboratory outcomes. Systematic screening for both co-infections is not routinely performed, and therefore the real prevalence of HIV/PvCo is unknown. This study showed a low prevalence of HIV/PvCo despite the high prevalence of malaria and HIV locally. Even though relatively small, this is the largest case series to describe HIV/PvCo.

AbstractIntroduction:Chorda tympani injury as a complication of middle-ear surgery has been extensively studied with regard to its effects upon taste. However, the chorda tympani also carries parasympathetic fibres to the salivary glands of the oral cavity. To date, little has been reported about the effect of chorda tympani section upon salivary function.Setting:Tertiary care centre.Material and methods:We report a case series of three patients with bilateral chorda tympani lesions. Chorda tympani function was assessed using ‘taste strips’ and unstimulated sialometry. A careful history of oral symptoms was taken.Results:All patients showed transient or permanent bilateral ageusia of the anterior two-thirds of the tongue, and a decreased resting salivary flow rate. In addition, all patients suffered from transient or persistent, distressing xerostomia.Conclusion:Taste disorders may occur after middle-ear surgery but they are mostly transient, even when the chorda tympani nerves are sectioned bilaterally. In contrast, bilateral chorda tympani lesions may lead to severe, persistent and distressing xerostomia. Based on this neglected aspect of chorda tympani function, we emphasise the importance of preserving the chorda tympani whenever possible.
