Background The usage and attitudes towards medical marijuana in Cystic Fibrosis (CF) patients is unknown. Through the use of a survey we aim to clarify rates and reasons for use. Methods An anonymous survey was sent out to six centers in the Mid-Atlantic region of the United States. Use of and reason for medical marijuana was assessed, along with attitudes of the perceived utility of medical marijuana. Results A total of 637 surveys were sent out, and 193 surveys were returned (30.3% return rate). Three did not give consent, and one was empty, for a total of 189 completed surveys. 31 subjects (16.5%) reported having used marijuana for medical purposes in their lifetime, with 29 (15.4%) of these in the past year. The most used forms were edible and vaporized. The most common indications for usage were pain and stress. 28 out of 31 found marijuana to be a great deal effective for their symptoms. 21 of the 31 rated marijuana very important or important to their health. There were two reported side effects, both mild. Of 156 subjects who responded to the question if they would be interested in medical marijuana if available, 72 (46.2%) replied yes. Conclusion The use of marijuana for medical reasons was 15.4% in the past year in this sample CF population, although more expressed interest if it was available through prescription. Side effects were rare. CF physicians are going to have to familiarize themselves with advantages and disadvantages of medical marijuana as there is a great deal of interest within the community, and legalization becomes more common.

Introduction Fecal impaction is a common occurrence in the elderly, with the most common risk factor being chronic constipation. A common cause of chronic constipation that can be overlooked in the elderly is hypothyroidism. If left untreated, hypothyroidism can have life-threatening manifestations including myxedema coma. In this case report, we describe a rare case of myxedema coma with prodromal fecal impaction. Case description An 87-year-old female with a past medical history of colon cancer status post partial colectomy, stroke, and end stage renal failure (ESRD) requiring hemodialysis, presented to the emergency department with extreme rectal pain. She was found to have fecal impaction on abdominal x-ray and was manually disimpacted and discharged home. Five days later, she presented with altered mental status in the setting of a new active herpes zoster infection and possible pneumonia. She was hypothermic (95F) and hypoxic, needing supplemental oxygen (2 L nasal cannula). Her labs showed hyponatremia (133 mg/dL), hypoglycemia (43 mg/dL), an elevated TSH level (100.0 mIU/ml) and decreased free T4 level (0.9 ng/L). Her EKG showed first-degree AV block with low voltage QRS complexes and her chest x-ray demonstrated bilateral pleural effusions. A CT scan of her head did not show hemorrhage or stroke. Given her classic clinical presentation and lab work findings, myxedema coma was diagnosed and the patient was treated with levothyroxine and hydrocortisone, though she was later transitioned to hospice as per her wishes. Discussion Chronic constipation is a known etiology of fecal impaction and can be caused by many chronic conditions in the elderly including ESRD, immobility, and hypothyroidism. Fecal impaction is easily identified but the investigation for the etiology is often overlooked. In this case, we argue that patients with an initial presentation of fecal impaction or with severe and unexplained constipation may warrant screening for hypothyroidism as a manageable risk factor for fecal impaction. By doing so, early recognition and treatment of hypothyroidism may prevent potentially fatal patient outcomes such as myxedema coma. Presentation: Saturday, June 11, 2022 1:00 p.m. - 3:00 p.m.
