Second branchial cleft anomaly with an ectopic tooth: a case report.

Branchial cleft cysts, sinuses, and fistulas are the most common congenital lateral neck lesions in children. They arise as a result of an abnormal development of the branchial arches and their corresponding ectoderm-lined branchial clefts. Of these diverse anomalies, second branchial cleft lesions are the most common, accounting for approximately 95% of all branchial arch pathologies.

Postpartum vertigo and superior semicircular canal dehiscence syndrome.

Background: Superior semicircular canal dehiscence is a recently described cause of imbalance, hearing loss, and tinnitus. Symptoms may begin after abrupt changes in intracranial or middle ear pressure.

Case: This patient presented with a 6-year history of imbalance, hearing loss, and pulsatile tinnitus beginning when she was pushing during labor.

Clinical features and treatment of retropharyngeal abscess in children.

Objective: To characterize presentation, treatment, and outcomes of pediatric retropharyngeal abscess (RPA) and determine optimal treatment.

Study Design: Retrospective cohort.

Subjects And Methods: Chart review of 162 pediatric patients with RPA.

Differential prognostic impact of comorbidity.

Purpose: Cancer patients with concurrent comorbid conditions have worse outcomes than patients with no comorbidities. We hypothesized that the prognostic impact of comorbidities would be greatest for patients with cancers associated with a long natural history and least in patients with aggressive cancers.

Patients And Methods: Using the Barnes-Jewish Hospital Oncology Data Services cancer registry, we grouped 11,558 patients with breast, lung, colon, or prostate cancer by morphologic stage at diagnosis and then determined the 1-year overall survival rate for each group.

The epidemiology of bronchioloalveolar carcinoma over the past two decades: analysis of the SEER database.

Bronchioloalveolar carcinoma of the lung (BAC) is a subtype of adenocarcinoma of the lung. Although traditionally grouped with other non-small cell lung carcinomas (NSCLC), BAC has unique morphological features and clinical behavior such as bilateral lung involvement, indolent course and lack of association with smoking. Some epidemiologic studies report a significant increase in the incidence of BAC.
