Infective Endocarditis in Hypertrophic Obstructive Cardiomyopathy After Etonogestrel Implant Removal.

The modified Duke criterion "predisposing heart condition" is poorly defined, and is based on outdated studies of the epidemiology of infective endocarditis (IE). Hypertrophic obstructive cardiomyopathy (HOCM) is not classified as a modified Duke criterion for the diagnosis of IE but is associated with a higher incidence of IE nonetheless. The presence of a cardiovascular implantable electronic device (CIED) is independently associated with an increased risk of IE. Patients with HOCM may be candidates for the implantation of an automated internal cardiac defibrillator (AICD) for the prevention of sudden cardiac death. Previous studies of the risk of IE in patients with HOCM did not make a distinction for patients with CIEDs. We present a case of a 25-year-old female with HOCM and an AICD for primary prevention, who presented with sudden right-sided hemiplegia, aphasia, dysarthria, and a low-grade fever. CT angiography demonstrated large vessel occlusion of the terminal left internal carotid artery and proximal middle cerebral artery (MCA), prompting emergent treatment with mechanical thrombectomy, which achieved full recanalization and full reperfusion. Cardioembolic stroke was suspected. She had no arrhythmias, a transthoracic echocardiogram showed new mitral valve vegetation. The etiology of the stroke was determined to be septic emboli from mitral valve subacute bacterial endocarditis and two blood cultures grew staph epidermidis. Ten days prior to presentation, she had undergone removal of an etonogestrel implant in her arm, and this was the suspected source of initial bacteremia and valvular seeding. She was treated with a six-week course of vancomycin with improvement and maintained on daily minocycline as long as the AICD were to remain in place. Our patient started developing symptoms of endocarditis after the removal of her etonogestrel implant, had no other recent procedures, and had good dentition. Hence, we maintain that this was the likely source of her initial bacteremia that led to valvular seeding and resultant IE. This is the first reported case of etonogestrel implant removal-related endocarditis. Further studies of the association between etonogestrel implant removal, transient bacteremia, and valvular seeding leading to IE are warranted. Clinicians should be reminded of the increased risk of IE in patients with HOCM. Identifying HOCM patients at higher risk for IE, i.e. dilated left atrium and/or CIEDs is easier to accomplish with current cardiac imaging techniques.

COVID-19 mRNA Vaccine-Associated Myocarditis Presenting as STEMI in a 48-Year-Old Male.

Myocarditis has been recognized as a rare complication of coronavirus disease 2019 (COVID-19) mRNA vaccinations. Young adult and adolescent males < 30 years of age are the most commonly affected group, with decreased incidence with older age. This is a case of a 48-year-old male who presented with chest pain and EKG findings of STEMI shortly after receiving the second dose of the Moderna COVID-19 mRNA vaccine. Emergent left heart catheterization revealed normal coronaries. Subsequently, the patient had rapid resolution of his symptoms and improvement in serum markers. The exact etiology factors to this new and rare phenomenon are yet to be fully understood. This patient did have a history of previous viral myocarditis 7 years ago; however, it remains unclear if this could be a predisposing factor to the development of mRNA vaccine-associated myocarditis.

Primary Pulmonary Choriocarcinoma Treated With Neoadjuvant Chemotherapy and Lobectomy: A Case Report.

Primary pulmonary choriocarcinomas (PPC) are a rare form of extragonadal germ cell tumors (GCT). They present as lung nodules and secrete beta-human chorionic gonadotropin (ß-HCG). This is a rare case of PPC that presented insidiously in a postmenopausal woman. Clinical suspicion arose due to markedly elevated serum ß-HCG and lung tumor biopsy immunohistochemical staining negative for markers of small cell and non-small cell carcinomas of the lung. The diagnosis of PPC was made after staining positive for markers of GCTs including ß-HCG in the absence of a primary tumor in the reproductive organs. The patient was treated with neoadjuvant vincristine, ifosfamide, and cisplatin (VIP) chemotherapy, followed by video-assisted thoracoscopic surgery (VATS) with lobectomy and mediastinal lymph node dissection. This is the first reported case of PPC treated with VIP induction chemotherapy. The patient initially had complete pathologic response and remission; however, she presented with relapse at a nine-month follow-up with new pulmonary nodules and metastatic disease to the brain.

Meropenem-Resistant Pandoraea Pneumonia in a Critically Ill Patient With COVID-19.

Among patients infected with respiratory viruses, primary coinfection or secondary bacterial pneumonia is common in the severely ill. Pandoraea are multi-drug resistant gram-negative bacilli that have been newly classified in the past 20 years. We present the first reported case of Pandoraea co-infection with SARS-CoV-2 infection. A critically ill gentleman with COVID-19 in acute respiratory distress syndrome (ARDS) requiring mechanical ventilation developed ventilator-associated bacterial pneumonia (VAP). Initial sputum cultures grew Pandoraea species, with subsequent cultures growing P. aeruginosa, and K. pneumoniae as well. The patient failed to improve despite several antibiotic regimens including meropenem. Send-out reference laboratory testing of the Pandoraea species showed susceptibility to amikacin, ciprofloxacin, levofloxacin, imipenem, and minocycline, but resistance to aztreonam, cefepime, ceftazidime, and meropenem. The patient had deteriorated to multi-organ failure by the time minocycline was initiated, and his family had transitioned him into hospice care. Carbapenems are vital agents in the treatment of VAP. Pandoraea species are often resistant to meropenem but often retain in-vitro sensitivity to imipenem-cilastin. Although mainly isolated from respiratory specimens of patients with cystic fibrosis, cases of infection in non-cystic fibrosis patients have been increasingly recognized. The presentation of this case aims to increase awareness of the high drug resistance of this rising species and reduce delays in treatment, especially in COVID-19 coinfection.

Fasting-Evoked En Route Hypoglycemia in Diabetes (FEEHD): An Overlooked Form of Hypoglycemia in Clinical Practice.

OBJECTIVE: Many patients with diabetes opt to fast for lab tests, especially for lipid profiles, thus missing breakfast. In parallel, recent studies and international guidelines have indicated that routine fasting for lipid panels may not be necessary. Missing breakfast while fasting for lab tests may invoke hypoglycemia, if patients are not properly instructed about adjusting diabetes medications on the night before or on the day of the lab test. Our group described this form of hypoglycemia and introduced the term FEEHD to refer to it (fasting-evoked en route hypoglycemia in diabetes). In a recently published small study, we reported a rate of occurrence of FEEHD of 27.1%. The objective of this study was to evaluate the rate of occurrence of FEEHD in another clinic. METHODS: Patients with diabetes were asked to complete a simple, 2-page survey inquiring about hypoglycemic events while fasting for labs in the preceding 12 months. RESULTS: A total of 525 patients completed the surveys out of 572 patients invited (91.8% response rate). A total of 363 patients with complete data were analyzed, with a mean age of 60.6 (SD 12.5) years. A total of 62 (17.1%) patients reported having experienced one or more FEEHD events in the prior 12 months. Of the 269 patients who were at higher risk of FEEHD (on insulin secretagogues or on insulin), 59 (21.9%) reported having experienced FEEHD. Only 33 of FEEHD patients (53%) recalled having contacted their provider regarding the events and only 22 (35%) indicated having received some sort of FEEHD prevention instructions. CONCLUSION: Our study shows a significant rate of occurrence of FEEHD in the real world (a clinical practice). FEEHD is especially dangerous, as patients often commute (drive) to and from the laboratory facility (potential risk of traffic accidents). Given study limitations, further studies are needed to assess prevalence of FEEHD in other settings and in the general populations.
