BACKGROUND: Temporal hollowing is a common complication following surgical dissection in the temporal region. Our objectives were to: (1) review and clarify the temporal soft tissue relationships - supplemented by cadaveric dissection - to better understand surgical approach variations and elucidate potential etiologies of postoperative hollowing; (2) identify if there is any evidence to support a surgical approach that prevents hollowing through a systematic review. METHODS: Cadaveric dissection was performed on six hemi-heads...

Using morphological, histological, and TEM analyses of the cranium, we provide a detailed description of bone and suture growth in zebrafish. Based on expression patterns and localization, we identified osteoblasts at different degrees of maturation. Our data confirm that, unlike in humans, zebrafish cranial sutures maintain lifelong patency to sustain skull growth. The cranial vault develops in a coordinated manner resulting in a structure that protects the brain. The zebrafish cranial roof parallels that of higher vertebrates and contains five major bones: one pair of frontal bones, one pair of parietal bones, and the supraoccipital bone...

REVIEW
Rahul Gosain, YaoYao Pollock, Dharamvir Jain
Aging poses an unique opportunity to study cancer biology and treatment in older adults. Breast cancer is often studied in young women; however, much investigation remains to be done on breast cancer in our expanding elderly population. Diagnostic and management strategies applicable to younger patients cannot be empirically used to manage older breast cancer patients. Lack of evidence-based data continues to be the major impediment toward delivery of personalized cancer care to elderly breast cancer patients...

Brazil's Pharma market is a dynamic and promising one. It ranks within the top ten market. There are peculiar hurdles that patentees have to overcome, such as, a two-tier examination, a serious backlog at the Brazilian Patent and Trademark Office. Several measures to accelerate examination have been adopted given the meager number of Examiners.

BACKGROUND: Trauma activation and/or leveling criteria are designed to balance the potential harm to individual patients from undertriage (UT) of severe injuries versus overutilization of resources from overtriage (OT) of lesser injuries. The American College of Surgeons (ACS) recommends an acceptable UT rate ≤5% and OT 25%-50%. To improve UT or OT, an intervention was performed to (1) improve accuracy in following established leveling criteria and (2) modify activation criteria in an evidence-based manner to better identify severely injured children...

BACKGROUND: Cleft lip represents one of the most common birth defects in the world. Although the timing of cleft lip repair is contingent on a number of factors, the "rule of 10s" remains a frequently quoted safety benchmark. Initially reported by Wilhelmsen and Musgrave in 1966 and modified by Millard in 1976, this rule referred to performing surgery once patients had reached cutoffs in weight, hemoglobin, and age/leukocyte count. Despite significant advances in both surgical and anesthetic technique, the oft-quoted "rule of 10s" has not been systematically investigated since its inception...

REVIEW
Regan F Williams, Israel Fernandez-Pineda, Ankush Gosain
Pediatric sarcomas are a heterogeneous group of tumors accounting for approximately 10% of childhood solid tumors. Treatment is focused on multimodality therapy, which has improved the prognosis over the past two decades. Current regimens focus on decreasing treatment for low-risk patients to decrease the long-term side effects while maximizing therapy for patients with metastatic disease to improve survival. Pediatric sarcomas can be divided into soft tissue sarcomas and osseous tumors. Soft tissue sarcomas are further delineated into rhabdomyosarcomas, which affect young children and nonrhabdomyosarcomas, which are most common in adolescents...

BACKGROUND: Attempted separation of craniopagus twins has continued to be associated with devastating results since the first partially successful separation with one surviving twin in 1952. To understand the factors that contribute to successful separation in the modern era of neuroimaging and modern surgical techniques, the authors reviewed and analyzed cases reported since 1995. METHODS: All reported cases of craniopagus twin separation attempts from 1995 to 2015 were identified using PubMed (n = 19)...

In this study polymeric micelles formed from poly(poly(ethylene glycol) methyl ether methacrylate)-block-poly(methyl methacrylate) (P(PEGMEMA75)-b-PMMA80) block copolymer of approximately 25nm in diameter were used to encapsulate the model drug, Nile Red, with a loading efficiency of 0.08wt% and a chemotherapeutic drug, doxorubicin (DOX), with an efficiency of 2.75wt%. The release of DOX from the micelles was sufficient to be cytotoxic to human colon carcinoma cells, WiDr, while Nile Red and the unloaded micelles were found not to be cytotoxic when exposed to the cells at polymer concentrations up to 200μg/mL...

BACKGROUND: Surgical wound classification (SWC) communicates the degree of contamination in the surgical field and is used to stratify risk of surgical site infection and compare outcomes among centers. We hypothesized that by changing from nurse-directed to surgeon-directed SWC during a structured operative debrief, we will improve accuracy of documentation. METHODS: An institutional review board-approved retrospective chart review was performed. Two time periods were defined: initially, SWC was determined and recorded by the circulating nurse (before debrief, June 2012-May 2013) and allowing 6 mo for adoption and education, we implemented a structured operative debriefing including surgeon-directed SWC (after debrief, January 2014-August 2014)...

Expression of Nodal, a Transforming Growth Factor-beta (TGF-β) related growth factor, is associated with aggressive melanoma. Nodal expression in adult dysplastic nevi may predict the development of aggressive melanoma in some patients. A subset of pediatric patients diagnosed with giant or large congenital melanocytic nevi (LCMN) has shown increased risk for development of melanoma. Here, we investigate whether Nodal expression can help identify the rare cases of LCMN that develop melanoma and shed light on why the majority of these patients do not...

Pulmonary hypertension (PH) in the setting of left-sided valvular heart disease is common, and significantly increases the risk of perioperative morbidity and mortality in patients undergoing aortic and/or mitral valve surgery. Minimally invasive valve surgery is associated with a decreased incidence of perioperative complications, and a faster recovery, when compared with conventional sternotomy. In the present study, the outcomes of 569 patients with PH who underwent minimally invasive aortic and/or mitral valve surgery were analysed...

Cluster of differentiation 1c (CD1c)-dependent self-reactive T cells are abundant in human blood, but self-antigens presented by CD1c to the T-cell receptors of these cells are poorly understood. Here we present a crystal structure of CD1c determined at 2.4 Å revealing an extended ligand binding potential of the antigen groove and a substantially different conformation compared with known CD1c structures. Computational simulations exploring different occupancy states of the groove reenacted these different CD1c conformations and suggested cholesteryl esters (CE) and acylated steryl glycosides (ASG) as new ligand classes for CD1c...

Plastic surgery research using large databases has increased dramatically over the past 20 years. With the magnitude and breadth of information available in these databases, researchers are able to more easily answer a wide variety of research questions. This study sought to provide a comprehensive comparative analysis of the relevant databases for plastic surgery research. Database information, data collection methods, acquisition details, and variable availability were collected for 19 large databases. Examples of potential future research utility were ascribed to each database based on this comprehensive analysis...
