This report presents an extremely rare case of -rearranged primary central mucoepidermoid carcinoma (MEC) of the mandible that was discovered as an incidental finding. Our review of the literature identified 36 cases of rearranged intraosseous lesions of the jaw (30 central MECs, 5 odontogenic cysts with mucous prosoplasia, and 1 glandular odontogenic cyst). Given the therapeutic indications for a diagnosis of MEC (a malignant neoplasm), rearrangement should be confirmed in suspected cases of central MEC.

Objectives: Acinic cell carcinoma of salivary gland harbours recurrent and specific chromosomal rearrangement [t(4;9)(q13;q31)], resulting in the translocation of secretory calcium-binding phosphoprotein gene cluster at 4q13 to nuclear receptor subfamily 4 group a member 3 at 9q31. This upregulates the transcription factor nuclear receptor subfamily 4 group A member 3, which can be detected by immunohistochemistry. The purpose of this pilot study is to evaluate the performance of nuclear receptor subfamily 4 group A member 3 immunostaining on whole-slide acinic cell carcinoma tissue, in comparison with discovered on GIST-1 immunostaining.

Objective: Secretory carcinoma (SC) of salivary gland is a recently described low-grade malignant neoplasm of the salivary gland, characterized by rearrangement of the ETV6 gene. SC of salivary gland shares striking morphologic, immunophenotypic, and molecular similarity to SC of breast.

Study Design: We report the clinicopathologic features of 4 ETV6-rearranged SCs of minor salivary gland and histopathologic diagnostic considerations.

Background: Research on the sexual behaviors of African American youth has primarily focused on associated risks, with a dearth of studies examining a fuller representation of African American adolescents' sexual lives. This study explored the range of messages African American adolescents receive from family members regarding sexual behavior and sexual relationships.

Methods: Participants were 52 sexually experienced African American youth (male = 32, female = 20) between the ages of 15 and 17 recruited from community-based organizations in the United States.

Background: Wake Up Safe is a quality improvement initiative of the Society for Pediatric Anesthesia that contains a deidentified registry of serious adverse events occurring in pediatric anesthesia. The aim of this study was to describe and characterize reported medication errors to find common patterns amenable to preventative strategies.

Methods: In September 2016, we analyzed approximately 6 years' worth of medication error events reported to Wake Up Safe.

We examined the potential for increasing the reach of HIV testing to African American youths through the dissemination of oral-HIV testing. From 2012 through 2013 we examined the perceptions of alternatives to pharmacy dissemination of SITs in African American youths (5 focus groups) and service providers (4 focus groups), and conducted an ethnographic study of pharmacies (n = 10). Participants perceived significant advantages to delivering SITs through community health and services for adolescents (e.

An 18 year old male presented with worsening headaches, pain with ocular movement and swelling that involved the left anterior periorbital and frontal sinus region. Radiographic images revealed a polypoid bony mass of mixed radiodensity extending into the left and right frontal sinuses. Histologic examination of the resection material resulted in the diagnosis of an osteoma with osteoblastoma-like features, an osteoma variant that has zones indistinguishable from an osteoblastoma.

In 2006, the Quality and Safety Committee of the Society for Pediatric Anesthesia initiated a quality improvement project for the specialty of pediatric anesthesiology that ultimately resulted in the development of Wake Up Safe (WUS), a patient safety organization that maintains a registry of de-identified, serious adverse events. The ultimate goal of WUS is to implement change in processes of care that improve the quality and safety of anesthetic care provided to pediatric patients nationwide. Member institutions of WUS submit data regarding the types and numbers of anesthetics performed and information pertaining to serious adverse events.

There is a dearth of research regarding the influence of family members on adolescent dating. This study explored messages that African American adolescents received from family members regarding dating attitudes, norms and behaviors. Qualitative interviews were conducted with sexually experienced urban African American heterosexual adolescents (N = 51) between the ages of 15-17.

Surgical safety has emerged as a significant global public health concern with reported mortality rates varying tremendously between developing and industrialized countries. This manuscript reviews some of the challenges encountered in providing safe anesthesia care in the humanitarian space; identifies the difficulties with providing high-quality education in developing countries; and describes how audits and quality improvement databases enhance our understanding of the nature and causes of harm to patients to inform the development of strategies for improvement.

Carbon dioxide embolism is a rare but potentially fatal complication of laparoscopic surgery. The most common cause is inadvertent injection of carbon dioxide into a large vein or solid organ during initial peritoneal insufflation. We describe a case of carbon dioxide embolism in a 13-year-old boy during an elective laparoscopic cholecystectomy, caused by injection of carbon dioxide into a large paraumbilical vein.

Unlabelled: Economic considerations suggest that it is desirable to keep operating rooms fully used when staffed, but the optimum utilization of an operating room (OR) is not known. We created a simulation of an OR to define optimum utilization. We set operational goals of having cases start within 15 min of the scheduled time and of having the cases end no more than 15 min past the scheduled end of the day.

We undertook to explore the validity of pain measurement tools for use in children in the postoperative period. The general approach was to determine the extent to which a measurement tool conformed with the clinical expectations about pain in the postoperative period; namely, that pain is low prior to surgery, increases following surgery, decreases with pain medication and decreases over time following surgery. In children aged 6 months to 3 years, we evaluated the CHEOPS and Observer pain scales.
