The prevalence of opioid misuse diagnostic codes in children with sickle cell disease.

Hospitalized patients with sickle cell disease (SCD) may use opioid medications for both acute and chronic pain management. Use of these medications may unintentionally generate diagnostic codes for opioid misuse including "opioid use," "opioid abuse," and "opioid dependence," which connote a behavioral problem or addiction. In this study, we sought to compare diagnostic codes for opioid misuse amongst hospitalized patients with and without SCD.

Novel insights into negative pressure wound healing from an in situ porcine perspective.

Negative pressure wound therapy (NPWT) is used clinically to promote tissue formation and wound closure. In this study, a porcine wound model was used to further investigate the mechanisms as to how NPWT modulates wound healing via utilization of a form of NPWT called the vacuum-assisted closure. To observe the effect of NPWT more accurately, non-NPWT control wounds containing GranuFoam™ dressings, without vacuum exposure, were utilized.

Sexual dimorphisms in three-dimensional masticatory muscle attachment morphometry regulates temporomandibular joint mechanics.

Temporomandibular joint (TMJ) disorders disproportionally affect females, with female to male prevalence varying from 3:1 to 8:1. Sexual dimorphisms in masticatory muscle attachment morphometry and association with craniofacial size, critical for understanding sex-differences in TMJ function, have not been reported. The objective of this study was to determine sex-specific differences in three-dimensional (3D) TMJ muscle attachment morphometry and craniofacial sizes and their impact on TMJ mechanics.

is a rod-shaped gram-negative obligate anaerobe; this organism, and other anaerobes, are usually not a part of the culture performed for a cerebrospinal fluid (CSF) sample. To date, four cases of meningitis in adults have been published. We report successful treatment of a case of primary meningitis due to in an otherwise healthy 72-year-old male.

Sub-clinical dose of bone morphogenetic protein-2 does not precipitate rampant, sustained inflammatory response in bone wound healing.

Large bone injuries, defects, and chronic wounds present a major problem for medicine. Several therapeutic strategies are used clinically to precipitate bone including a combination therapy delivering osteoinductive bone morphogenetic protein 2 (rhBMP-2) via an osteoconductive scaffold (absorbable collagen sponge [ACS], i.e.

How well do we manage the odontogenic keratocyst? A multicenter study.

Objective: The aim of this study was to answer the following clinical questions: Among patients treated for odontogenic keratocysts (OKCs), what is the overall 5-year disease-free rate, and what factors are associated with disease recurrence?

Study Design: We implemented a multicenter retrospective cohort study composed of patients presenting for the evaluation and management of previously untreated OKCs. The predictor variables were grouped into demographic, medical, radiographic, and operative categories. The primary outcome variable was time to lesion recurrence.

Perineurioma of the Tongue: A Case Report and Review of the Literature.

A perineurioma (PN) is a rare benign peripheral nerve sheath tumor derived from perineurial cells. Based on clinical and pathologic features, PNs can be classified into 2 major subtypes: intraneural PN (IPN) and the more common extraneural PN (EPN). EPNs and IPNs are extremely rare in the oral cavity, and there have been only 38 reported cases (21 EPNs, 17 IPNs).

Optimizing bone wound healing using BMP2 with absorbable collagen sponge and Talymed nanofiber scaffold.

Background: Bone is a highly vascularized and resilient organ with innate healing abilities, however some bone injuries overwhelm these attributes and require intervention, such as bone tissue engineering strategies. Combining biomaterials and growth factors, such as bone morphogenetic protein 2 (BMP2), is one of the most commonly used tissue engineering strategies. However, use of BMP2 has been correlated with negative clinical outcomes including aberrant inflammatory response, poor quality bone, and ectopic bone.

Perspective: Sistas In Science - Cracking the Glass Ceiling.

In this perspective, we describe our experience as women of color scientists from diverse backgrounds and similar struggles embarking upon the National Heart, Lung and Blood Institute-funded program called PRIDE (Programs to Increase Diversity among Underrepresented Minorities Engaged in Health-Related Research). Under the leadership of our mentor and friend, Betty Pace, MD, a renowned and successful African American physician-scientist, the PRIDE Program was designed to address the difficulties experienced by junior-level minority investigators in establishing independent research programs and negotiating tenure and full professor status at academic institutions. The strength of PRIDE's innovative formula was pairing us with external senior mentors and, importantly, allowing us to serve as peer mentors to each other.

Three-dimensional temporomandibular joint muscle attachment morphometry and its impacts on musculoskeletal modeling.

In musculoskeletal models of the human temporomandibular joint (TMJ), muscles are typically represented by force vectors that connect approximate muscle origin and insertion centroids (centroid-to-centroid force vectors). This simplification assumes equivalent moment arms and muscle lengths for all fibers within a muscle even with complex geometry and may result in inaccurate estimations of muscle force and joint loading. The objectives of this study were to quantify the three-dimensional (3D) human TMJ muscle attachment morphometry and examine its impact on TMJ mechanics.

Effect of Measurement Technique on TMJ Mandibular Condyle and Articular Disc Morphometry: CBCT, MRI, and Physical Measurements.

The study objective was to determine the 3-dimensional morphometry of the temporomandibular joint (TMJ) condyle and articular disc using cone-beam computed tomography (CBCT), magnetic resonance imaging (MRI), and physical measurements of the same joints using a repeated measures design and to determine the effect of the measurement technique on temporomandibular size and shape.

Materials And Methods: Human cadaveric heads underwent a multistep protocol to acquire physiologically meaningful measurements of the condyle and disc.

Testing a novel nanofibre scaffold for utility in bone tissue regeneration.

Many variables serve to alter the process of bone remodelling and diminish regeneration including the size and nature of the wound bed and health status of the individual. To overcome these inhibitory factors, tissue-engineered osteoconductive scaffolds paired with various growth factors have been utilized clinically. However, many limitations still remain, for example, bone morphogenetic protein 2 (BMP2) can lead to rampant inflammation, ectopic bone formation, and graft failure.

Involvement of calvarial stem cells in healing: A regional analysis of large cranial defects.

Large craniofacial defects present a substantial clinical challenge that often requires the use of osteoconductive matrices and osteoinductive cues (i.e., bone morphogenetic proteins [BMP2]) to augment healing.
