Intramural Hematoma and Retroperitoneal Hematoma Following a Routine Colonoscopy: An Uncommon Complication of a Common Procedure.

Colonoscopy is used worldwide for screening colon cancer. Routine colonoscopy is considered a safe procedure with relatively fewer adverse events. We present a case of intracolonic and retroperitoneal hematoma following a routine colonoscopy. This case highlights an uncommon life-threatening complication of a common procedure. A 50-year-old female presented with abdominal pain and syncopal episode following an uneventful screening colonoscopy. CT abdomen revealed intracolonic and retroperitoneal hematoma. This eventually led to exploratory laparotomy and right hemicolectomy after failure of conservative management. Clinicians need to be aware of the potentially life-threatening complications associated with colonoscopy for overall safety of colonoscopy.

A Case Report of Flecainide Toxicity With Review of Literature.

Flecainide is an anti-arrhythmic drug with a narrow therapeutic index. Flecainide toxicity is rare, but the mortality is high. This case demonstrates the use of intravenous fat emulsion therapy in conjunction with intravenous sodium bicarbonate treatment for flecainide toxicity. A 50-year-old male with atrial fibrillation and taking flecainide 75 mg twice daily presented to Emergency Department after ingesting 1125 mg of flecainide, in a suicide attempt. An electrocardiogram (ECG) on arrival showed bradycardia, wide QRS complex, prolonged QTc interval. Treatment for flecainide poisoning with intravenous sodium bicarbonate was initiated. On day two, the patient had a cardiac arrest secondary to ventricular tachycardia. After successful defibrillation, the patient had persistent bradycardia and hypotension. Administration of a 20% lipid emulsion bolus, followed by continuous infusion for three hours, resulted in conversion to normal sinus rhythm. This case illustrates the successful treatment of flecainide toxicity with intravenous fat emulsion therapy. To our knowledge, this is the second case that used fat emulsion without concomitant extracorporeal life support. Due to its low prevalence and the fact the lipid emulsion is often used in conjunction with other treatments, there are no randomized clinical trials on the isolated efficacy of lipid infusion. The best treatment is unknown. Given its high mortality, early detection and treatment are paramount.

COVID-19 Coinfection with Mycobacterium abscessus in a Patient with Multiple Myeloma.

BACKGROUND: Coronavirus disease (COVID-19) is a worldwide pandemic causing multiple fatalities and morbidities worldwide. We report a case of severe pneumonia causing acute respiratory distress syndrome due to a coinfection with SARS-CoV-2 and Mycobacterium abscessus in an elderly patient with multiple myeloma in Florida, USA. Case Presentation. An 84-year-old male with a medical history significant for multiple myeloma not in remission was sent to the emergency department to rule out COVID-19 infection prior to continuing his chemotherapy sessions. At presentation, he had nonspecific mild symptoms and an unremarkable physical examination. He had significant blood test findings including serum lactate dehydrogenase 373 U/L, high sensitive C-reactive protein 17.40 mg/l, and ferritin 415 ng/ml. Xpert-SARS-CoV-2 was positive. Chest radiograph revealed patchy areas of interstitial infiltrates in mid to lower lung zones. During his hospitalization course, his oxygenation deteriorated, requiring mechanical intubation. Repeat chest radiograph showed worsening bilateral infiltrates. He was started on broad-spectrum antibiotics and eventually weaned off mechanical intubation and extubated. On the 11th day of admission, he was found to be bradycardic and in shock, and he was reintubated. His labs showed worsening inflammatory markers along with kidney dysfunction to the point of requiring renal replacement therapy. He received both convalescent plasma and remdesivir for treatment of COVID-19 pneumonia. Eventually, repeat blood cultures came back positive for the growth of acid-fast beaded bacilli. While awaiting final culture and sensitivity reports, his antibiotics were upgraded to cover possible nocardia infection. Repeat blood and sputum cultures resulted in growth of AFB bacilli Mycobacterium abscessus 1 week after. CONCLUSIONS: This case report highlights the importance of keeping a broad differential and considering multiple coinfections, including atypical ones during this COVID-19 pandemic, such as the one that was discussed above, Mycobacterium abscessus, in order to provide goal-directed therapy.

A Case of Plasmodium falciparum Malaria Treated with Artesunate in a 55-Year-Old Woman on Return to Florida from a Visit to Ghana.

BACKGROUND Malaria is the infection caused by inoculation with the mostly obligate intraerythrocytic protozoa of the genus Plasmodium. Severe malaria manifests as multiple organ dysfunction with high parasitemia counts characterized by coma, stupor, and severe metabolic acidosis. Physicians in the United States do not frequently encounter patients with malaria, and the drugs are only available through the Centers for Disease Control and Prevention, which makes the management of this disease somewhat complicated. In 2019, the marketing of quinine for malaria was discontinued. In May 2020, the US Food and Drug Administration approved the use of intravenous artesunate for the treatment of adults and children with severe malaria. This case report describes a case of Plasmodium falciparum malaria in a 55-year-old woman who returned home to Florida from a visit to Ghana. CASE REPORT A previously healthy 55-year-old woman with no significant past medical history presented to the Emergency Department (ED) of a hospital in south Florida due to cyclic fever for 7 days. The patient's family reported mental status changes since symptom onset. The patient had returned from a 10-day trip to Ghana 18 days prior to admission. On arrival to the ED, the patient appeared lethargic and within hours was in respiratory distress. She was intubated and mechanically ventilated in the ED for acute hypoxemic respiratory failure. A malaria smear was positive with 25% parasitemia, and a diagnosis of severe malaria was made, consistent with P. falciparum infection complicated by multi-organ failure. Infectious disease consultation was obtained and an infusion of intravenous (IV) quinidine and IV doxycycline was emergently started due to the anticipated delay in obtaining artesunate. During the second day of admission, the patient had QTc prolongation, so quinidine was switched to IV artesunate. The parasitemia and acidosis started improving by the third day of therapy. CONCLUSIONS Given that artesunate is more effective, easier to dose, and more tolerable than quinidine, it is now the treatment of choice for severe malaria in the United States.

Alcoholic Hepatitis: A Common Disease with Uncommon Presentation.

Alcoholic liver disease is one of the leading causes of hepatitis, cirrhosis, liver failure, and hepatic carcinoma. Alcoholic hepatitis refers to the acute onset of symptomatic hepatitis. We describe a patient who presented with alcoholic hepatitis with direct hyperbilirubinemia, elevated alkaline phosphatase (ALP), and hypertriglyceridemia. All the imaging and laboratory work excluded obstructive causes, and liver biopsy confirmed the diagnosis. Alcoholic hepatitis is a common condition, but some unusual presentations can lead one to think of uncommon pathologies. This case reflects that alcoholic hepatitis can present with high levels of triglycerides as well as a cholestatic pattern with direct hyperbilirubinemia and ALP without an obvious obstruction cause.
