Workplace- and Residence-Associated Leptospirosis: A Case Report and Review of Current Literature.

Leptospirosis is a zoonotic infection most commonly occurring in tropical regions through contact with water or soil contaminated with animal urine. In New York, approximately one to three cases occur annually, the majority occurring through workplace exposure to animal reservoirs. In cases of the more severe presentation of leptospirosis, Weil's disease, it is important to identify the infection promptly to allow for early antibiotic initiation as well as early initiation of daily dialysis in cases in which it is necessary.

Azithromycin-Induced Liver Injury in an Asthma Exacerbation Patient With Autoimmune Features.

Drug-induced liver injury (DILI) is one of the leading causes of acute liver failure in the United States. Antimicrobials are the most common class of drugs implicated in this pathology. Although azithromycin has been documented as a relatively safe drug, one of its rare and potentially fatal side effects is DILI.

Brown Tumor With Spine Involvement at Multiple Levels in a Hemodialysis Patient.

Brown tumor of the bone or osteitis fibrosa cystica is a rare manifestation of hyperparathyroidism, most seen nowadays in association with secondary and tertiary hyperparathyroidism. Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are the major culprits of secondary hyperparathyroidism (sHPTH). CKD is known to cause phosphate retention and a decrease in 1,25-dihydroxyvitamin D and ionized calcium levels, which in turn trigger the PTH secretion.

Recurrent Rhabdomyolysis Induced by Severe Hypothyroidism.

Hypothyroidism is frequently associated with myalgias, muscle stiffness, easy fatigability, and occasionally some degree of myopathy with mildly elevated muscle enzymes. Rarely, hypothyroidism may be complicated by rhabdomyolysis, the rapid destruction of skeletal muscle with myoglobin, creatine kinase, urate, and electrolytes release into the circulation. Recurrent cases of rhabdomyolysis are uncommon as most patients experience only one episode of rhabdomyolysis in their lifetime.

A Rare Case of Vagus Nerve Schwannoma Presenting as a Neck Mass.

BACKGROUND Vagus nerve schwannoma is a benign neoplasm that usually presents as an asymptomatic slow growing mass, and its presentation as a neck mass is rare. The diagnosis can be difficult to make and complete surgical excision is challenging due to the proximity of the vagus nerve fibers from which it originates. The most common symptom associated with vagus nerve schwannoma arising in the neck is hoarseness due to vocal cord palsy.
