Wooden chest syndrome (WCS) describes a finding of fentanyl-induced skeletal muscle rigidity causing ventilatory failure. Known primarily to anesthesiology, pulmonary, and critical care fields, WCS is a rare complication that may affect patients of all ages if exposed to intravenous fentanyl, characterized by a patient’s inability to properly ventilate. Given the rise of synthetic opioid deaths across the United States in the past decade, an understanding of all of fentanyl’s effects on the body is necessary. In this article, we present a case of WCS in a patient with acute respiratory distress syndrome in a 61-year-old female.

Background Coronavirus disease 2019 (COVID-19) is a manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-COV2), which results in many different complications including left ventricular thrombi. Case summary We present a 30-year-old female presenting with chest pain and shortness of breath. Patient had an extensive history including heart failure with ejection fraction 15-20% and COVID-19 two months ago. Echocardiogram revealed a 3.3 cm x 1.7 cm left ventricular (LV) thrombus which was not present four months ago before her diagnosis of COVID-19. The LV thrombus embolized resulting in in an embolus extending from the distal infrarenal abdominal aorta to the common iliac arteries bilaterally. Repeat COVID pre-procedure was positive. She underwent bilateral femoral artery cutdown, bilateral iliac artery embolectomy, superficial femoral artery embolectomy and bilateral lower extremity fasciotomy. An extensive workup for the etiology of the LV thrombus turned out to be negative and COVID-19 was deemed to be the etiology of the thrombus. The patient was bridged from apixaban to warfarin and was successfully discharged within a few weeks. Discussion Hypercoagulability is a known complication of COVID-19 causing thrombi in various parts of the body including the LV. Early recognition with echocardiography, especially in patients with heart failure, and prompt treatment is key to avoid further complications such as embolization.

Cystocerebral syndrome is an often forgotten cause of delirium in elderly males, which is quite easily treated. We reviewed the current body of literature documenting cystocerebral syndrome and proposed a new mechanism of action explaining why all patients identified thus far have been male. Data was obtained from articles describing cases of cystocerebral syndrome, urinary retention, and confusion in addition to delirium via a PubMed database search. We reviewed all articles describing cases of cystocerebral syndrome via the PubMed database using the Medical Subject Headings (MeSH) keywords of "cystocerebral syndrome,” urinary retention and confusion," and "delirium and urinary retention or cystocerebral syndrome," and identified eight cases of cystocerebral syndrome including the original publication by Blackburn and Dunn. We found that all patients reported in the literature were males older than 70 years and often with concomitant benign prostatic hypertrophy (BPH) who presented with acute episodes of delirium that rapidly responded to bladder decompression. The authors seek to update the medical community regarding this uncommon phenomenon of delirium in elderly male patients. We also propose that the lack of female patients in the literature is reflective of their decreased intraurethral flow resistance as is currently being described in other avenues of research in the field of urodynamics.
