Pediatric Dental Clinic-Associated Outbreak of Mycobacterium abscessus Infection.

Background: Mycobacterium abscessus is an uncommon cause of invasive odontogenic infection.

Methods: M abscessus-associated odontogenic infections occurred in a group of children after they each underwent a pulpotomy. A probable case-child was defined as a child with facial or neck swelling and biopsy-confirmed granulomatous inflammation after a pulpotomy between October 1, 2013, and September 30, 2015.

Operative management of choanal atresia: a 15-year experience.

Objective: To analyze factors affecting 15-year surgical outcomes of choanal atresia repair.

Design: Case series.

Setting: Tertiary care pediatric hospital.

Viral response to chemotherapy in endemic burkitt lymphoma.

Purpose: Some EBV-directed therapies are predicted to be effective only when lytic viral replication occurs. We studied whether cyclophosphamide chemotherapy induces EBV to switch from latent to lytic phases of infection in a series of EBV-associated Burkitt lymphomas.

Experimental Design: Children with first presentation of an expanding, solid maxillary or mandibular mass consistent with Burkitt lymphoma underwent fine-needle aspiration just prior to the initiation of cyclophosphamide therapy and again 1 to 5 days later.
