Challenging Diagnosis: Babesiosis With a Coincidental Intraabdominal Mass.

Babesiosis is a tick-borne disease caused by an intraerythrocytic parasite known as spp. Its clinical presentation is often nonspecific and can range from asymptomatic to life-threatening, depending on the host's immune status. This myriad of manifestations potentially overlaps with other familiar conditions such as hematologic malignancy.

The Heart Remembers: A Case of Cardiac Memory.

An 80-year-old male with a history of atrial fibrillation and a single-chamber ventricular pacemaker presented to the hospital for an elective colonoscopy. He experienced a transient episode of unresponsiveness with seizure-like activity before the procedure. This prompted him to get an EKG showing deep T-wave inversions (TWIs) in the precordial leads on a background of paced beats.

Crusted Scabies Induced Hypereosinophilic Syndrome.

Crusted scabies causes extensive hyperkeratotic skin lesions, crusting, and scaling and is common in elderly and institutionalized patients. We present a case of crusted scabies in a patient with encephalopathy and diffuse exfoliative erythroderma. After extensive workup, the patient's condition was attributed to hypereosinophilic syndrome due to crusted scabies.

Efficacy and safety of direct oral anticoagulant in morbidly obese patients with atrial fibrillation: systematic review and meta-analysis.

Aims: We conducted a systematic review and meta-analysis on three outcomes. We assessed the efficacy and safety of direct oral anticoagulants (DOAC) compared to vitamin K antagonists (VKA) in morbidly obese patients with atrial fibrillation (AF). We compared the efficacy and safety of DOAC in obese patients and non-obese patients with AF.

Autoimmune necrotizing myopathy after statin discontinuation.

We report a case of autoimmune necrotizing myopathy related to statin use in a 70-year-old woman who came to the hospital because of progressive lower extremity weakness. Laboratory, electromyography and muscle biopsy results were consistent with autoimmune necrotising myopathy. The patient was treated with intravenous immunoglobulin with improvement in muscle strength.

An Unusual Presentation of Severe Sepsis Due to Clostridium difficile Enteritis.

We report an atypical case of Clostridium difficile (C.difficile) infection in a 35-year male who presented to the hospital because of diffuse abdominal pain associated with nausea and vomiting. Patient denied diarrhea or hematochezia.

Does Right Ventricular Dysfunction Predict Mortality in Hemodynamically Stable Patients With Acute Pulmonary Embolism?

Background: Acute pulmonary embolism (APE) is directly responsible for 100,000 deaths annually. Right ventricular dysfunction (RVD) on admission is considered a poor prognostic factor in these patients, though existing evidence of its significance in predicting mortality in hemodynamically stable patients is still unclear. We attempted to clarify this association by doing a retrospective review.

Does Syncope Predict Mortality in Patients With Acute Pulmonary Embolism? A Retrospective Review.

Background: Acute pulmonary embolism (APE) is a potentially fatal disease with high mortality. Prior studies have shown an increased frequency of central localization of the clot, right ventricular dysfunction and elevated troponin in patients who present with syncope and APE. Existing evidence regarding mortality and length of hospital stay in these patients is unclear.

Salicylate-induced pulmonary edema--a near-miss diagnosis.

A 43-year-old white woman presented to the emergency department with confusion, agitation, and progressive dyspnea. Chest x-ray revealed pulmonary edema. Initial diagnostic considerations were pneumonia, pulmonary embolism, sepsis, central nervous system infection, substance toxicity, and heart failure.

Pneumocystis pneumonia during primary HIV infection: a case report and review of the literature.

More than 90% of cases of pneumocystis pneumonia (PCP) in adults occur in patients with chronic HIV infection with CD4 counts lower than 200 cells/ml. Even though primary HIV infection can cause transient profound CD4 lymphocytopenia, PCP is rarely reported during primary HIV infection. We report a case of a 26-year-old man who was diagnosed with PCP in the setting of primary HIV infection.

Life-threatening hypocalcemia associated with denosumab in a patient with moderate renal insufficiency.

Denosumab, a human monoclonal antibody to the receptor activator of nuclear factor-κB ligand, is a novel therapy to osteoporotic fracture and skeletal-related events in patients with bone metastases. Hypocalcemia is its known adverse effect, although it is generally mild and transient and usually occurs in patients with severe chronic kidney disease or end-stage renal disease. We reported a case 61-year-old woman who received a single dose of denosumab and developed severe symptomatic hypocalcemia associated with prolong QTc interval requiring hospitalization for intravenous calcium.
