RESUMO
Meningitis due to Staphylococcus aureus is extremely rare, with an annual incidence of 1-3%. In this report, we present a rare case involving meningitis, an infected graft, and an infected fluid collection with two forms of S. aureus in a patient who received a bovine brain graft status post-decompression and suboccipital craniectomy with C1 laminectomy and duraplasty for Chiari malformation. The treatment approach included surgical debridement and graft retention, followed by an extended course of antibiotic treatment with oxacillin and rifampin. The patient successfully completed 12 weeks of total antibiotic therapy and was transitioned to suppressive therapy indefinitely with cefadroxil. This case highlights the importance of prompt identification and treatment of S. aureus meningitis due to the high mortality associated with this disease.
RESUMO
Since the onset of the COVID-19 pandemic, to date, around 385 million cases have been diagnosed worldwide leading to an estimated 5.7 million death toll. Mass vaccination campaigns have been conducted to control the spread of infection with the most commonly used vaccines being Pfizer-BioNTech and Moderna. However, the adverse effects of vaccination have not yet been fully investigated. Of concern are some serious cardiovascular events such as myocarditis, pericarditis, or perimyocarditis development post-vaccination. Hemorrhagic pericardial effusion has not been reported. However, we report a case of myopericarditis with a hemorrhagic pericardial effusion that developed two weeks following BNT162b2 mRNA COVID-19 vaccination. We performed a complete workup identifying the underlying cause that did not yield any significant findings. Our patient was treated with colchicine and ibuprofen, and he made a full recovery. A follow-up cardiovascular magnetic resonance imaging (CMR) showed no signs of active inflammation.
RESUMO
We present a novel case of recurrent brain abscesses found to be the result of a silent congenital right-to-left extracardiac shunt, a persistent left superior vena cava draining into the left atrium. The patient's brain abscess was evacuated surgically and treated with antibiotics, and his shunt was subsequently repaired. The case suggests that attention should be paid to evaluation for shunt physiology allowing for bypass of the pulmonary circulation in those with recurrent brain abscesses.
RESUMO
Corynebacterium is a rare cause of prosthetic joint infections (PJIs) and infection after fracture fixation (IAFF). We present a case of a patient who developed Corynebacterium jeikeium-associated IAFF three weeks after his fracture fixation. Due to its slow-growing nature, surgical cultures remained negative after 72 hours and grew only on day 5. We highlight that physicians should have Corynebacterium-associated infection in their differential in such cases, especially when the cultures remain negative after 72 hours. We also review the literature of PJI and implant-associated infection with C. jeikeium and discuss the antibiotic resistance patterns and some microbiological considerations associated with C. jeikeium.
RESUMO
Endocarditis and cardiac device infection due to Mycobacterium fortuitum is a rare entity in the hospital settings. We report a case of pacemaker infection and native valve endocarditis due to Mycobacterium fortuitum, which was associated with tricuspid valve vegetation. two days after admission with fever, chills, body aches and swelling around her pacemaker, the patient's pacing system was surgically removed. The patient was then discharged at day 16 after surgery and treated with a multidrug regimen of azithromycin, levofloxacin, imipenem/cilastatin, and amikacin for six weeks followed by trimethoprim/sulfamethoxazole plus doxycycline for a further three months.
RESUMO
Raoultella species are a group of gram-negative, non-motile bacilli commonly isolated from the environment. The group was considered a member of the genus Klebsiella until the late 1990s. Raoultella planticola is a rare cause of human infections. We report the first case of liver abscess caused by this organism. The patient was successfully treated with appropriate antimicrobials combined with operative drainage.
RESUMO
UNLABELLED: Babesia is known to be prevalent in the Eastern United States and other temperate countries but the prevalence of babesia is not well known in the tropical malaria-endemic countries because of the higher prevalence of malaria. A 72-year-old Hispanic male from Ecuador presenting with increasing left lower quadrant abdominal pain and distention for one year. He experienced nausea, vomiting, diarrhea, fever, chill, and myalgias. He reported 9 kg weight loss over the last two months. Patient moved to Chicago recently from Ecuador where he worked at a banana plantation and had frequent exposure to many insects and animals. Vital signs were normal but patient appeared chronically ill. Mild tenderness to palpation over the left side of the abdomen with marked splenomegaly, measuring 16 cm below the costal margin. Laboratory results with no leukocytosis hemoglobin 7.8 × 10(9)/L; and platelet count, 55 × 10(9)/L. Sodium was 128 mmol/L. Labs showed elevated LDH, ESR and ferritin values. The haptoglobin was low with a positive Combs test. CT abdomen showed moderate splenomegaly with large patchy, wedge-shaped hypodense area in posterior mid and upper spleen suggesting splenic infarction. Rapid malaria screening was negative, but a peripheral smear identified plasmodium species in more than 0.5% of red blood cells. Treatment with atovaquone and proguanil started. Two weeks later, molecular testing revealed Babesia DNA. This report details a case of babesiosis in a patient coming from a malaria-endemic region. The initial workup and blood work highly suggested a plasmodium infection. However the polymerase chain reaction confirmed the diagnosis of a Babesia microti. LEARNING OBJECTIVES: We report the first case of human Babesiosis in previously healthy individual from Ecuador.
RESUMO
A 25-year-old male with no past medical history presented with 1 day of chest pain. The patient had exercised with high intensity for a bodybuilding competition. He had fever, malaise, sore throat, and cough 1 week before presentation. He was tachycardic and tachypneic. Cardiac examination was unremarkable. Electrocardiogram showed diffuse ST segment elevation. Laboratory results showed leukocytosis, creatinine kinase 3078 unit/L, and troponin I 78.06 ng/mL. Coronary angiography revealed no occlusion. Echocardiogram showed ejection fraction of 45% with global hypokinesis. The next day, the patient became dyspneic, hypoxic, and hypotensive. Chest X-ray showed pulmonary edema requiring intubation for respiratory failure. Inotropic support and intra-aortic balloon pump were started. A viral panel was ordered and antibody titer of coxsackievirus B type 4 was ≥1:640. On obtaining further history, it was found that he took liothyronine 75 mcg daily for 3 weeks. Thyroid-stimulating hormone was 0.015 U/mL and free T3 was 4.4 ng/mL. Burch-Wartofsky score was 75. Methimazole and hydrocortisone were started. Cardiac magnetic resonance imaging showed diffuse myocardial inflammation and edema. There was multifocal dense epicardial and midmyocardial necrosis in all segments. The patient was discharged on metoprolol and enalapril. The patient was instructed to refrain from supplements.
