RESUMO

This case report discusses a 28-year-old patient who presented with a large expansile lesion of the right mandible. A maxillofacial CT showed a 6.7 x 9.1 x 7.6 cm right mandibular cystic mass containing an internal matrix of ground glass bone, representing a huge odontogenic keratocyte. Upon biopsy of the lesion, the specimen consisted of non-decalcified irregular fragments of cemento-osseous material, embedded in a minimally hemorrhagic, cellular fibrous tissue stroma, suggestive of central ossifying fibroma. This case presents an ossifying fibroma that far exceeds the average size of these masses, which typically range from 1.0 to 2.5 cm at its greatest dimension. The immense size of the lesion seen in this case is rarely encountered. This case also helps to emphasize the importance of timely diagnosis and complete resection of the lesion to prevent mass recurrence and possible malignant transformation.

RESUMO

Langerhans cell histiocytosis (LCH) is a rare proliferative disease of myeloid cells that can affect multiple organs and present with diverse clinical manifestations. The skeleton, skin and lymph nodes are commonly affected sites, while oral involvement is rare. LCH is currently classified by disease extent into single system and multisystem forms, and further categorized by risk organs. The purpose of this report is to describe the case of a six-month-old girl who presented with a chief complaint of feeding difficulties, premature eruption of the primary left maxillary second molar, expansion of the maxillary alveolar ridges and ulceration of the posterior maxillary oral mucosa. The diverse presentations of pediatric LCH in the literature are reviewed and the role of pediatric dentists and oral surgeons in helping to diagnose LCH is highlighted.

RESUMO

BACKGROUND: Routine preoperative laboratory testing is not recommended for American Society of Anesthesiologists classification 1 or 2 patients before low-risk ambulatory surgery. METHODS: The 2017 National Surgical Quality Improvement Program data set was retrospectively queried for American Society of Anesthesiologists class 1 and 2 patients who underwent low-risk, elective outpatient anorectal, breast, endocrine, gynecologic, hernia, otolaryngology, oral-maxillofacial, orthopedic, plastic/reconstructive, urologic, and vascular operations. Preoperative laboratory testing was defined as any chemistry, hematology, coagulation, or liver function studies obtained ≤30 days preoperatively. Demographics, comorbidities, and outcomes were compared between those with and without testing. The numbers needed to test to prevent serious morbidity or any complication were calculated. Laboratory testing costs were estimated using Centers for Medicare and Medicaid Services data. RESULTS: Of 111,589 patients studied, 57,590 (51.6%) received preoperative laboratory testing; 26,709 (46.4%) had at least 1 abnormal result. Factors associated with receiving preoperative laboratory testing included increasing age, female sex, non-White race/ethnicity, American Society of Anesthesiologists class 2, diabetes, dyspnea, hypertension, obesity, and steroid use. Mortality did not differ between patients with and without testing. The complication rate was 2.5% among tested patients and 1.7% among patients without tests (P < .01). The numbers needed to test was 599 for serious morbidity and 133 for any complication. An estimated $373 million annually is spent on preoperative laboratory testing in this population. CONCLUSION: Despite American Society of Anesthesiologists guidelines, a majority of American Society of Anesthesiologists class 1 and 2 patients undergo preoperative laboratory testing before elective low-risk outpatient surgery. The differences in the rates of complications between patients with and without testing is low. Preoperative testing should be used more judiciously in this population, which may lead to cost savings.
