Observational Study
Lactated Ringer's solution and risk of hyperkalemia in patients with reduced kidney function.
Emerging evidence supports the superiority of balanced crystalloids such as Lactated Ringer's (LR) compared to normal saline but concerns for the development of hyperkalemia have limited its use. Although LR inherently contains potassium, there exists a paucity of evidence to suggest that LR could potentiate hyperkalemia. To address this, we evaluated the effect of LR on serum potassium in patients with reduced kidney function who are at risk of developing hyperkalemia. ⋯ LR use was not independently associated with the development of hyperkalemia in patients with reduced kidney function.

Review Case Reports
Romosozumab used to treat a patient with cystic fibrosis-related osteoporosis.
Bone disease is a known complication of cystic fibrosis (CF). To date, there have been no reports on the effectiveness of romosozumab, monoclonal antibody to sclerostin, to treat CF-related bone disease. We report a case of a 46-year-old premenopausal female with CF-related bone disease and multiple fractures who was treated with romosozumab. ⋯ Of the currently available anti-resorptive or anabolic osteoporosis medications, only bisphosphonates have been studied in individuals with CF. This report highlights that romosozumab may be an effective alternative treatment modality in selected patients with CF at high risk for fractures. Further studies are warranted to evaluate the efficacy and safety profile of romosozumab in people with CF.

Review Case Reports
Synthetic cannabinoids and ST elevation myocardial infarction: A case report and systematic review of the literature.
Synthetic cannabinoids cannot be detected on a standard urine drug screen (UDS), making them a convenient drug of abuse. We report the first case of ST elevation myocardial infarction (STEMI) in a young patient due to coronary artery thrombosis secondary to synthetic cannabinoid use and concurrent COVID-19 infection. A 38-year-old previously healthy male developed severe chest pain and was found to have anterior STEMI and COVID-19 infection. ⋯ He only required supportive care for COVID-19. A comprehensive literature search revealed 34 additional cases of STEMI with synthetic cannabinoid use; majority were males (97%) with mean age of 29 years. 29 patients (85.3%) underwent coronary angiography and majority had left anterior descending artery (LAD) involvement (55%), with 13 (44.8%) undergoing stent placement. We highlight STEMI as a potentially lethal complication of synthetic cannabinoids; prompt angiography may be lifesaving.

Review Case Reports
Mimicking the mimicker: Necrotizing sarcoid granulomatosis.
Necrotizing sarcoid granulomatosis (NSG) is a rare disease that shares similarities with pulmonary vasculitides and sarcoidosis. This is a report of two cases of NSG with a review of literature. The first case is a 33-year-old black female with a one-year history of malaise and cough. ⋯ Pathology often shows necrotizing granulomatous vasculitis, distinguishing it from classical sarcoid. Laboratory markers for vasculitis like neutrophil cytoplasmic antibodies and antibodies against myeloperoxidase and proteinase 3 are negative or only low titers. NSG responds well to immune-suppression, most commonly with glucocorticoids.

Diuretics are amongst the most prescribed medications in both the inpatient and outpatient settings. They are used extensively in diverse disease states including heart failure, acute and chronic kidney disease, cirrhosis, and diseases of excess capillary permeability such as sepsis, malignancy, and malnutrition. All are characterized by total body sodium overabundance which commonly manifests as edema. ⋯ These complications frequently limit the correction of hypervolemia, resulting in continued patient suffering and frustration for the clinician. In this review, we employ a case-based approach to discuss three common challenges encountered during diuretic therapy: diuretic resistance that characterizes the nephrotic syndrome, diuretic-induced metabolic alkalosis, and diuretic-associated hyponatremia. We empower the clinician to effectively meet these challenges by providing a mechanistic understanding of these complications and their solutions.
