RESUMEN
Sixteen percent of patients referred for cardiology evaluation are found to have no cause for palpitations. Studies show that hypertension intricately influences "heart rate" and "contractility,?" the key components of "palpitation." While the prevalence of hypertension is 22.4% in 18-39-year-olds, the relationship between palpitations and hypertension remains unknown in this age group. In our study, we assessed the incidence and prevalence of hypertension over 5 years in 18-40-year-olds referred for palpitations who had no known arrhythmic cause for palpitations between January 1, 206 and December 31, 2017. We found that over a period of 2.2 (0.7-4.1) years, an additional 56% patients were diagnosed with stage 1 (65/130) and stage 2 (28/130) hypertension, increasing the prevalence from 16% at the start of the study period to 72% at the end of the study period (p < .0001). Hypertensive patients were obese (BMI: 29 [24-36] kg/m2 vs. 25 [22-31] kg/m2; p = .03), used nonsteroidal anti-inflammatory drugs (NSAIDs) (62 vs. 35%; p = .04), had a stronger family history of hypertension (55 vs. 4%; p < .0001) and exhibited higher systolic (124[120-130] mmHg vs. 112[108-115] mmHg; p < .0001) and diastolic (80[76-83] mmHg vs. 72[69-75] mmHg; p < .0001) blood pressures. Hypertension is commonly diagnosed in 18-40-year-old predominantly white female patients referred for palpitations without a known arrhythmic cause. The possibility of untreated hypertension causing palpitations in this cohort needs further evaluation.

Hyperkalemia refractory to standard temporization measures can be life-threatening, and urgent hemodialysis is often utilized as a final resort. Our patient presented with hyperkalemia that was multifactorial in etiology, with acute kidney injury complicated by adrenal insufficiency. Her hyperkalemia was refractory to temporization and excretion agents, and hemodialysis was being considered. Given a recent infection, surgery, and borderline hypotension with low adrenocorticotropic hormone, there was a concern for adrenal insufficiency. However, a full investigation for secondary adrenal insufficiency via magnetic resonance imaging could not be conducted as the patient suffered from claustrophobia. Continued concern for adrenal insufficiency prompted the initiation of intravenous hydrocortisone, and the patient's hyperkalemia resolved within 24 hours. While suspected adrenal insufficiency is already a basis for stress-dose steroids in the setting of pathologies such as severe sepsis, clinicians should have a low threshold for considering refractory hyperkalemia alone as an indication for stress-dose steroids. When dialysis is being considered as an option, this treatment modality should be given even more consideration. Adopting this practice may not only lead to improved mortality from hyperkalemia but also lead to fewer patients being exposed to the risks of dialysis.
RESUMEN
CONTEXT: Diabetic ketoacidosis (DKA) is an endocrine emergency that can occur in people with diabetes. Its incidence is estimated to be 220,340 hospital admissions each year. Treatment algorithms include fluid resuscitation, intravenous (IV) insulin infusion, and scheduled electrolyte and glucose monitoring. The misdiagnosis of DKA in the setting of hyperglycemic emergencies results in overtreatment and unnecessary increases in healthcare utilization and costs. OBJECTIVES: The aims of this study were to determine how often DKA is overdiagnosed in the context of other acute hyperglycemic emergencies, to describe the baseline characteristics of patients, to determine the hospital treatments for DKA, and to identify the frequency of endocrinology or diabetology consultation in the hospital setting. METHODS: A retrospective chart review was conducted utilizing charts from three different hospitals within a hospital system. Charts were identified utilizing ICD-10 codes for admissions to the hospital for DKA. If the patient was over 18 and had one of the diagnostic codes of interest, the chart was reviewed for further details regarding the criteria for DKA diagnosis as well as admission and treatment details. RESULTS: A total of 520 hospital admissions were included for review. DKA was incorrectly diagnosed in 28.4â¯% of the hospital admissions reviewed, based on a review of the labs and DKA diagnostic criteria. Most patients were admitted to the intensive care unit (ICU) and treated with IV insulin infusion (n=288). Consultation of endocrinology or diabetology occurred in 40.2â¯% (n=209) of all hospital admissions, and 128 of those consults occurred in ICU admissions. The diagnosis of DKA was incorrect in 92 of the patients admitted to the medical surgical unit (MSU) and in 49 of patients admitted to the ICU. CONCLUSIONS: Almost one third of hospital admissions for hyperglycemic emergencies were misdiagnosed and managed as DKA. DKA diagnostic criteria are specific; however, other diagnoses like hyperosmolar hyperglycemic syndrome (HHS), hyperglycemia, and euglycemic DKA can make an accurate diagnosis more complicated. Education directed at improving the diagnostic accuracy of DKA among healthcare providers is needed to improve diagnostic accuracy, ensure the appropriate use of hospital resources, and potentially reduce costs to the healthcare system.

Ethyl chloride is a common topical anesthetic. However, when abused as an inhalant, effects can range from headaches and dizziness to debilitating neurotoxicity requiring intubation. While previous case reports describe the short-term reversible neurotoxicity of ethyl chloride, ours show chronic morbidity and mortality outcome. During the initial evaluation, it is essential to consider the rising trend of commercially available inhalants being used as recreational drugs. We present a case of a middle-aged man presenting with subacute neurotoxicity due to repeated abuse of ethyl chloride.
RESUMEN
Diabetic ketoacidosis (DKA) with hypernatremia is an atypical metabolic derangement that warrants additional consideration in choosing IV fluids. Our patient, a middle-aged male with a history of insulin-dependent diabetes mellitus type 2 and hypertension, presented with DKA and hypernatremia in the setting of poor intake, community-acquired pneumonia (CAP), and COVID-19. DKA and hypernatremia led to a meticulous approach to fluid resuscitation, where a crystalloid solution was the choice in treating and preventing exacerbation of either condition. Successful treatment of these conditions requires understanding the unique pathophysiology, which demands further research on management.
RESUMEN
INTRODUCTION: Dofetilide suppresses atrial fibrillation (AF) in a dose-dependent fashion. The protective effect of AF against QTc prolongation induced torsades de pointe and transient post-cardioversion QTc prolongation may result in dofetilide under-dosing during initiation. Thus, the optimal timing of cardioversion for AF patients undergoing dofetilide initiation to optimize discharge dose remains unknown as does the longitudinal stability of QTc . The purpose of this study was to evaluate the impact of baseline rhythm on dofetilide dosing during initiation and assess the longitudinal stability of QTc-all (Bazzett, Fridericia, Framingham, and Hodges) over time. METHODS: Medical records of patients who underwent preplanned dofetilide loading at a tertiary care center between January 2016 and 2019 were reviewed. RESULTS: A total of 198 patients (66 ± 10 years, 32% female, CHADS2 -Vasc 3 [2-4]) presented for dofetilide loading in either AF (59%) or sinus rhythm (SR) (41%). Neither presenting rhythm, nor spontaneous conversion to SR impacted discharge dose. The cumulative dofetilide dose before cardioversion moderately correlated (r = .36; p = .0001) with discharge dose. Postcardioversion QTc-all prolongation (p < .0001) prompted discharge dose reduction (890 ± 224 mcg vs. 552 ± 199 mcg; p < .0001) in 30% patients. QTc-all in SR prolonged significantly during loading (p < .0001). All patients displayed QTc-all reduction (p < .0001) from discharge to short-term (46 [34-65] days) that continued at long-term (360 [296-414] days) follow-ups. The extent of QTc-all reduction over time moderately correlated with discharge QTc-all (r = .54-0.65; p < .0001). CONCLUSION: Dofetilide initiation before cardioversion is equivalent to initiation during SR. Significant QTc reduction proportional to discharge QTc is seen over time in all dofetilide-treated patients. QTc returns to preloading baseline during follow-up in patients initiated in SR.

Diabetic ketoacidosis (DKA) and hyponatraemia associated with beer potomania are severe diagnoses warranting intensive care level management. Our patient, a middle-aged man, with a history of chronic alcohol abuse and insulin non-compliance, presents with severe DKA and severe hyponatraemia. Correcting sodium and metabolic derangements in each disorder require significant attention to fluid and electrolyte levels. Combined they prove challenging and require an individualised approach to prevent the overcorrection of sodium. Furthermore, management of these conditions lends to the importance of understanding the pathophysiology behind their hormonal and osmotic basis.
