Patient: Male, 47Final Diagnosis: Pulmonic valve endocarditisSymptoms: Fever • myalgiaMedication: —Clinical Procedure: —Specialty: CardiologyObjective:Rare diseaseBackground:Infective endocarditis (IE) has a high mortality rate, even when treated with appropriate antibiotic therapy and surgical intervention. Right-sided endocarditis is in itself rare, with some studies reporting an incidence of 5–10%. The majority of these cases involve the tricuspid valve, and isolated pulmonary valve endocarditis (PVE) is an extremely rare entity affecting less than 2% of patients with infective endocarditis. Identification and early management are crucial to prevent long-term complications and reduce mortality.Case Report:We present a patient with a history of essential hypertension and no underlying valvular disease, who underwent dental cleaning and subsequently developed low-grade fever, myalgia, and malaise. This occurred during the flu season, and was initially diagnosed and treated as flu, without any improvement. The patient was later found to be bacteremic with S. mitis, with no identifiable source, and a normal transthoracic echocardiogram (TTE). He was later hospitalized, had a transesophageal echocardiogram, and was found to have a large pulmonic valve vegetation.Conclusions:This case presents an interesting and rare finding of endocarditis, isolated to the pulmonic valve, in an otherwise healthy individual with no predisposing risk factors. The lack of peripheral stigmata, as well as an unremarkable initial outpatient TTE, made the diagnosis more difficult. It should also be noted that current guidelines do not specifically address right-sided endocarditis, and do not specify the role of surgical intervention.

Background:Acute alcohol intoxication has been associated with cardiac arrhythmias but the electrocardiogram (ECG) changes associated with acute alcohol intoxication are not well defined in the literature.Objective:Highlight the best evidence regarding the ECG changes associated with acute alcohol intoxication in otherwise healthy patients and the pathophysiology of the changes.Methods:A literature search was carried out; 4 studies relating to ECG changes with acute alcohol intoxication were included in this review.Results:Of the total 141 patients included in the review, 90 (63.8%) patients had P-wave prolongation, 80 (56%) patients had QTc prolongation, 19 (13.5%) patients developed T-wave abnormalities, 10 (7%) patients had QRS complex prolongation, 3 (2.12%) patients developed ST-segment depressions.Conclusion:The most common ECG changes associated with acute alcohol intoxication are (in decreasing order of frequency) P-wave and QTc prolongation, followed by T-wave abnormalities and QRS complex prolongation. Mostly, these changes are completely reversible.

The incidence rate of chronic lymphocytic leukemia (CLL) in the United States is approximately 0.005%; men are at slightly higher risk than women. Bony involvement or pathological fracture rarely occurs in CLL, and it may be the initial presentation. An 85-year-old woman presented with acute respiratory failure secondary to pneumonia. Symptomatology included dyspnea. She was found to have pathological fracture of the femur caused by CLL. The diagnosis of CLL had been made 6 years previously, but the patient had refused therapy. On admission, the patient required endotracheal intubation, mechanical ventilation, and admission to the medical intensive care unit. Endotracheal intubation extubation was successful after 48 hours. The patient then complained of severe left knee pain. Bone radiograph and femoral computed tomography scan revealed acute pathological fracture of the left distal femur. There was no history of trauma. The fracture was stabilized with extension lock splint. Pathological fracture in patients with CLL is associated with hypercalcemia, Richter’s transformation, or multiple myeloma. This patient exemplifies the fact that pathological fracture can be caused by CLL in the absence of hypercalcemia, Richter’s transformation, or multiple myeloma and can be the initial presentation of CLL.

Although most intracardiac defects are congenital, a small fraction may be acquired during life. The Gerbode defect is an abnormal anatomical connection between the left ventricle and the right atrium. We describe herein a patient who initially underwent repair of tetralogy of Fallot (TOF). Years after TOF repair, he developed severe dyspnea. Extensive evaluation revealed that he had developed a Gerbode defect. Very few cases of acquired Gerbode defect have been previously reported. Management options are predominantly surgical interventions.

Infliximab therapy is associated with higher rates of active tuberculosis (TB), particularly extrapulmonary and disseminated forms with unusual symptoms. We report the case of a 66-year-old man with Crohn’s disease who developed TB mimicking lung cancer on imaging. He presented with cough and fever of 2 weeks’ duration shortly after starting infliximab. Computed tomography of the chest revealed a 7.0 × 3.2 cm2 pleural-based mass, highly suspicious for malignancy. Histopathological examination confirmed the diagnosis of TB. The mass disappeared after antitubercular treatment, and the patient recovered completely. A review of the literature suggests that TB masquerades as lung cancer clinically and radiologically. The classical lesions of TB are cavitatory with calcifications. Mass lesions without cavity or calcifications are rare and are mostly reported from regions endemic for TB. The majority of patients on infliximab therapy required biopsy for accurate diagnosis of TB because of its unusual presentation.
