Oral Secondary Syphilis.

Secondary syphilis develops in approximately 25% of patients infected with the spirochete bacterium Treponema pallidum. It typically develops several weeks to several months after the primary infection, which is recognized by a painless chancre. Secondary syphilis is characterized by systemic symptoms, such as malaise and fever as well as a maculopapular rash involving the trunk and extremities including the palms and soles.

Multimodality imaging evaluation of an uncommon entity: esophageal heterotopic pancreas.

A 25-year-old male was referred to the Radiology Department with new onset of right upper quadrant and epigastric abdominal pain. He had no past medical or surgical history. Physical exam was unremarkable.

Sudden cardiac death associated with methylone use.

The rise in popularity of "bath salts" as safe alternatives to MDMA (3,4-methylenedioxymethamphetamine), methamphetamine, and other illicit substances has resulted in increased scrutiny of the contents and toxicology associated with these products. We report a case of sudden death related to the synthetic cathinone methylone (3,4-methylenedioxy-N-methylcathinonmethylone) in a previously healthy 19-year-old man. Although several fatal case reports have been published involving methylone and other synthetic cathinones, this is the first reported case of sudden cardiac death associated with methylone use.

Antibiotic therapy for pediatric deep neck abscesses: a systematic review.

Objective: To evaluate the current evidence regarding the safety and efficacy of medical management for deep neck abscesses in children.

Data Sources: Pubmed and Embase databases accessed 3/27/2012.

Review Methods: An a priori protocol defining inclusion and exclusion criteria was developed to identify all articles addressing medical therapy of pediatric deep neck abscesses where details regarding diagnostic criteria, specifics of medical therapy and definitions of failure were presented.

Paranasal sinus mucocele.

Paranasal sinus mucoceles are epithelium-lined cystic masses usually resulting from obstruction of sinus ostia. They most frequently occur in the frontal and ethmoid sinuses. While ophthalmologic symptoms are most common, patients also report rhinological or neurological complaints.

External auditory osteoma.

External auditory canal (EAC) osteomas are rare, benign bony neoplasms that occur in wide range of patients. While chronic irritation and inflammation have been suggested as causal factors in several cases, significant data is lacking to support these suspicions. Symptoms are rare and can include hearing loss, vertigo, pain and tinnitus.

Posterior remodeling of medial clavicle causing superior vena cava impingement.

Injuries involving the sternoclavicular region resulting in posterior displacement of the medial clavicle are rare, and those that occur prior to fusion of the medial epiphyseal growth plate are more often a result of physis fracture, rather than sternoclavicular joint dislocation. Medial clavicular physis fractures initially are treated by closed reduction with the expectation of normal osseous repair and remodeling. We report a case of a previously fractured medial clavicle physis that abnormally remodeled, was reinjured, and resulted in posterior displacement with superior vena cava impingement and brachioplexopathy.
