Although rare, fibroepithelial polyp of the ureter is the most common type of benign urinary tract mesodermal tumor. It may cause symptoms such as hematuria, dysuria, and flank pain or be asymptomatic. Here we report incidental intraoperative detection of a left ureteral fibroepithelial polyp during an elective gyno-oncological surgery for left-sided ovarian thecoma.A 13-year-old boy presented with acute kidney injury, abdominal discomfort, and distention secondary to urinary ascites. He had undergone a robotic-assisted laparoscopic excision of a urachal cyst 5 years prior to presentation. Further examination revealed decreased urine output, elevated serum creatinine, and hyperkalemia. He was diagnosed with rapidly progressive glomerulonephritis requiring hemodialysis. Further investigation of ascites fluid demonstrated significantly elevated creatinine consistent with urine. A computed tomography cystogram demonstrated an intraperitoneal bladder rupture. He underwent an emergent surgical cystorrhaphy with significant improvement.Delayed posthypoxic leukoencephalopathy is a rare condition that can occur following prolonged cerebral hypo-oxygenation and manifests as acute onset of neuropsychiatric symptoms after a period of apparent recovery. We describe a case of a 76-year-old man who presented after an unwitnessed fall of unknown duration with initial recovery followed by progressive neurocognitive decline resulting in dementia, dysphasia, and gait apraxia. Initial brain magnetic resonance imaging was unremarkable but repeated brain imaging revealed progressive leukoencephalopathy, which started as small foci of abnormal diffusion restriction in bilateral frontal lobes and gradually evolved over the next 3 weeks to diffuse signal changes in the white matter.After incurring bilateral tibial fractures and developing sizable hematomas at the trauma sites, a child experienced 4 days of fever with an elevated C-reactive protein level and sedimentation rate. As thrombotic and infectious etiologies were ruled out, the patient's febrile and inflammatory response was likely attributable to hematoma formation. Hematomas are a recognized cause of noninfectious fever. Local release of pyrogenic cytokines within the hematoma may be the source for elevation in temperature and inflammatory markers.A 53-year-old male mountain biker received a total artificial heart and remained in the cardiovascular intensive care unit for 56 days. To reduce functional decline caused by inactivity, he performed a six-session cycle ergometer exercise program in his hospital room. Traditional cardiac responses for exercise prescription were not applicable; therefore, a symptom-limited, monitored progression scheme in conjunction with recommendations for the artificial heart was implemented to modify duration and intensity. Over the six sessions, the patient improved his distance pedaled by 320% and functional capacity by 1 metabolic equivalent. He was subsequently discharged from the hospital and later successfully transplanted without readmission.Lemierre's syndrome (LS) is a pharyngeal infection complicated by infectious jugular vein thrombosis and septic emboli. Most commonly caused by Fusobacterium necrophorum, it may result in metastatic infection, especially when antibiotic treatment is delayed. Patients with LS are often healthy adults between 16 and 30 years who present with prolonged symptoms of pharyngitis, lateral neck pain, and fever. Other symptoms may include shortness of breath, tachycardia, and hypotension. When administered promptly, antibiotics can act as an effective treatment. However, complications may arise that require additional intervention. Herein, we report a case of LS in a young adult, complicated by severe pleural effusions that required surgical decortication.BRASH syndrome is a relatively novel clinical entity with profound bradycardia secondary to simultaneous metabolic derangement and drug toxicity. The syndrome is a clinical pentad of bradycardia, acute kidney injury, use of atrioventricular nodal blocking agents, shock, and hyperkalemia. It is widely underrecognized with selectively few reports, mainly in the elderly population. We present a 43-year-old woman on two oral atrioventricular blocking agents who presented with 1 week of increasing lethargy with rapid deterioration into cardiac arrest with subsequent shock postresuscitation. She was found to have hyperkalemia, metabolic acidosis, and acute kidney injury on arrival. Her initial electrocardiogram was remarkable for sinus arrest and junctional bradycardia. She was treated with a temporary pacemaker, renal replacement therapy, and potassium-lowering agents, with subsequent improvement resulting in conversion to normal sinus rhythm.Thrombotic complications such as venous thromboembolism, ischemic stroke, and myocardial infarction have emerged as causes of significant morbidity and mortality in patients infected with COVID-19. We present a 32-year-old man who developed a large saddle pulmonary embolus secondary to COVID-19 infection and underwent successful bilateral percutaneous pulmonary artery mechanical thrombectomy.Constrictive pericarditis is rare after cardiac surgery, with a time to presentation ranging from 82 days to 204 months. We report a 75-year-old man who underwent aortic valve replacement and developed constrictive pericarditis 21 years later. He underwent a pericardiectomy with pericardial stripping, which confirmed constrictive pericarditis and improved his symptoms.Acute bacterial pericarditis is rarely encountered in the modern antibiotic era. Purulent pericarditis is a serious form of bacterial pericarditis with high mortality. sirpiglenastat It can rapidly progress to cardiac tamponade, leading to hemodynamic instability, septic shock, and death if left untreated. Here we present a case of massive purulent pericarditis with cardiac tamponade that was successfully managed with intravenous antibiotics and drainage in a young immunocompetent man.Much research has focused on the association between the toxic metabolites of the tactical herbicide Agent Orange and several blood cancers, including systemic amyloid light-chain (AL) amyloidosis. Here we present a rare case of heart failure secondary to cardiac AL amyloidosis as a consequence of Agent Orange exposure. An elderly man was transferred to the intensive care unit for a suspected gastrointestinal bleed and decompensation of congestive heart failure. An echocardiogram suggested restrictive cardiomyopathy, and an abdominal fat pad biopsy confirmed amyloid involvement. The diagnosis of systemic AL amyloidosis was made following a free lambda to free kappa light chain ratio >31. Upon discussion with the patient, significant exposure to Agent Orange during deployment was affirmed. Subsequent care was taken over by the Veterans Affairs Medical Center.
