Wooden Chest Syndrome: A Case Report of Fentanyl-Induced Chest Wall Rigidity.

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.

Severe acute respiratory syndrome coronavirus 2-induced acute aortic occlusion: a case report.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 infection can lead to a constellation of viral and immune symptoms called coronavirus disease 2019. Emerging literature increasingly supports the premise that severe acute respiratory syndrome coronavirus 2 promotes a prothrombotic milieu. However, to date there have been no reports of acute aortic occlusion, itself a rare phenomenon. We report a case of fatal acute aortic occlusion in a patient with coronavirus disease 2019. CASE REPORT: A 59-year-old Caucasian male with past medical history of peripheral vascular disease presented to the emergency department for evaluation of shortness of breath, fevers, and dry cough. His symptoms started 5-7 days prior to the emergency department visit, and he received antibiotics in the outpatient setting without any effect. He was found to be febrile, tachypneic, and hypoxemic. He was placed on supplemental oxygen via a non-rebreather mask. Chest X-ray showed multifocal opacifications. Intravenous antibiotics for possible pneumonia were initiated. Hydroxychloroquine was initiated to cover possible coronavirus disease 2019 pneumonia. During the hospitalization, the patient became progressively hypoxemic, for which he was placed on bilevel positive airway pressure. D-dimer, ferritin, lactate dehydrogenase, and C-reactive protein were all elevated. Severe acute respiratory syndrome coronavirus 2 reverse transcription polymerase chain reaction was positive. On day 3, the patient was upgraded to the intensive care unit. Soon after he was intubated, he developed a mottled appearance of skin, which extended from his bilateral feet up to the level of the subumbilical plane. Bedside ultrasound revealed an absence of flow from the mid-aorta to both common iliac arteries. The patient was evaluated emergently by vascular surgery. After a discussion with the family, it was decided to proceed with comfort-directed care, and the patient died later that day. DISCUSSION: Viral infections have been identified as a source of prothrombotic states due to direct injury of vascular tissue and inflammatory cascades. Severe acute respiratory syndrome coronavirus 2 appears to follow a similar pattern, with numerous institutions identifying elevated levels of thrombotic complications. We believe that healthcare providers should be aware of both venous and arterial thrombotic complications associated with coronavirus disease 2019, including possible fatal outcome.

Cystocerebral Syndrome: An Updated Review and a New Proposed Mechanism for an Often Forgotten Cause of Delirium.

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.

Efficacy of antibacterial envelope in prevention of cardiovascular implantable electronic device infections in high-risk patients: A systematic review and meta-analysis.

BACKGROUND: Limited evidence is available to determine the efficacy of an antibacterial enveloped (AE) cardiovascular implantable electronic device (CIED). OBJECTIVE: To assess if the use of antibacterial enveloped devices in high-risk patients are associated with lower chances of major CIED infections and mortality compared to non-enveloped devices. METHODS: A comprehensive literature search on multiple databases was performed. The relative odds ratio (OR) of major CIED infection and mortality was calculated using a random-effect model. RESULTS: A total of six studies consisting of 11,897 patients, were included; 5844 with an AE-CIED and 6053 with conventional CIED. In the pooled cohort, patients with AE-CIED had a 66% lower odds of major CIED infection (OR 0.34, 0.13, 0.86, CI 95%, p = 0.02) compared to CIED. Propensity matched analysis showed a 71% lower odds of major infection in the AE-CIED group (OR 0.29, 95% CI 0.10-0.82, p = 0.02). Stratified analysis based on the type of study (retrospective vs. prospective) and duration of follow up (6 months vs. greater than six months) also showed numerically lower infection odds in the AE-CIED. Similarly, the relative odds of mortality were lower in patients with AE-CIED (OR 0.55, 95% CI 0.16-1.91, p = 0.34) compared to CIED patients; however, this difference was statistically non-significant. CONCLUSION: In high-risk patients, AE-CIED might offer lower odds of CIED infections. It has numerically lower (45%) but statistically non-significant odds of mortality if used in conjunction with the standard infection prevention protocol. More large scale studies and long-term follow-ups are required to validate our findings.

A Rare Case of Bleeding Epiphrenic Esophageal Diverticulum From Arteriovenous Malformations.

Epiphrenic esophageal diverticula (EED) is a rare condition that usually presents with dysphagia in patients with a known motility disorder. In this article, we present a unique case of EED presenting with hemoptysis with clinical workup negative for any pulmonary pathology. Esophagogastroduodenoscopy revealed arteriovenous malformations within the EED successfully managed with argon plasma coagulation (APC), leading to a resolution of the patient's symptoms.
