Introduction: In city hospitals, subway-related traumatic amputations are a frequent pattern of injury, however there is a paucity of literature on this specific injury pattern. The purpose of this study was to describe the epidemiology of subway-related traumatic amputations, as well as compare them to non-subway traumatic amputations.
Patients And Methods: Retrospective review was performed at a single Level-1 trauma center in a metropolitan area.

Chopart's amputation is a limb length-preserving amputation that retains function but often suffers from stump ulcerations. We report a case of a 68-year-old male patient with poorly controlled type 2 diabetes mellitus and peripheral arterial disease who underwent left Chopart's amputation, presenting subsequently with nonhealing ulcers at the Chopart stump and heel for >1 year. Total contact casting was initiated, resulting in rapid wound healing without further interventions.

Our study aimed to compare the outcomes of two-stage revision of CP and CN PJI using the standardized Musculoskeletal Infection Society (MSIS) outcome reporting tool. We retrospectively reviewed 138 patients who were diagnosed with PJI and indicated for two-stage revision total knee arthroplasty (rTKA).

In this regard, genomic studies of chromatin states within cancerous tissues have the potential to uncover novel aspects of tumor biology and unique mechanisms associated with disease phenotypes and outcomes. The degree to which chromatin state differences occur in accordance with breast cancer features has not been established.

Experimental testing in space is difficult and expensive. However, reducing buoyancy by decreasing ambient pressure is a possible approach to simulate on-earth the burning behavior inside spacecraft environments.

Spacecraft smoke detectors will ideally detect smoke generated by oxidative pyrolysis (such as smoldering) in order to allow the maximum time for the crew to respond before a larger flaming fire develops. An experiment on the International Space Station (ISS) characterized smoke from overheating common spacecraft materials.

Moreover, experimental testing in spacecraft environments can be difficult and expensive, so using ground-based tests to inform microgravity tests is vital. Reducing buoyancy effects by decreasing ambient pressure is a possible approach to simulate a spacecraft environment on earth.

Sterilization and synthetic polymers that degrade in a commensurate fashion with wound healing have been the most significant improvements in these age-old devices. However, the constricting loop of a traditional suture and subsequent ischemia ("approximate, don't strangulate") still account for the most common cause of wound dehiscence-necrosis.

Design: Retrospective chart review.
Setting: Military, hospital-based, sleep center.
Background: Compliance with continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA) is highly variable. Recent studies suggest that the initial experience with CPAP may determine long-term success. We hypothesized that administration of a hypnotic medication to new CPAP users would facilitate acclimation and increase usage.

They are also capable of shifting tissues differentially along the suture to redistribute tensile and compressive forces.
View Article and Find Full Text PDFBackground: Suture knots present several disadvantages in wound closure, because they are tedious to tie and place ischemic demands on tissue. Bulky knots may be a nidus for infection, and they may extrude through skin weeks after surgery. Needle manipulations during knot-tying predispose the surgeon to glove perforation.

A retrospective analysis of 828 patients with significant midface or mandibular fractures was undertaken to illustrate the multisystem nature of traumatic injuries associated with fracture of the facial skeleton, covering the period from 1985 to 1994. Special emphasis was placed on determining associated injuries sustained as well as epidemiological information. The experience presented differs from other large series in the literature in that the predominant mechanism of injury is motor vehicle accidents (67%) rather than assaults.

A genetic predisposition to resistance (R)/susceptibility (S) has been demonstrated for cowdriosis in certain goal lines. In order to identify genetic markers of R/S and to follow their transmission to the offspring, 4 groups of sires and dams were crossbred in 1991, 1992, and 1993: Rr, RS, SR, and SS. The offspring were challenged at the age of six months with subsequent challenge of the S parent.

Twelve immunocompromised patients illustrating three patterns of infection were treated recently at the Duke University Medical Center. These groups comprised (I) locally aggressive infections, (II) indolent infections, and (III) cutaneous manifestations of systemic infection.

Simply increasing the number of elements used in the reconstruction process throughout the domain is generally an unsatisfactory method to achieve higher resolution because additional multiview data are required. Here a new series-expansion reconstruction procedure, based on isoparametric finite-element concepts, is described.

Diagnoses included pansynostosis (7), craniofrontonasal dysplasia (8), and Apert (24), Crouzon (15), and Pfeiffer (15) syndromes. All patients underwent primary fronto-orbital advancement-calvarial vault remodeling procedures at less than 18 months of age (mean 6.

As the first of a two-part series, 104 patients with isolated craniofacial synostosis were retrospectively analyzed. Diagnoses included bilateral coronal (10), unilateral coronal (57), metopic (29), and sagittal synostosis (8).
