Techniques of peripheral nerve repair.

Nerve injuries extend from simple nerve compression lesions to complete nerve injuries and severe lacerations of the nerve trunks. A specific problem is brachial plexus injuries where nerve roots can be ruptured, or even avulsed from the spinal cord, by traction. An early and correct diagnosis of a nerve injury is important. A thorough knowledge of the anatomy of the peripheral nerve trunk as well

Review of The theater of trauma: American modernist drama and the psychological struggle for the American Mind.

Reviews the book, The theatre of trauma: American modernist drama and the psychological struggle for the American mind by M. Cotsell (2005). The author's main thesis is that American modernist dramaturgy was mostly propelled by representations of trauma and the ensuing dissociation, contrary to the usual interpretation that it was powerfully influenced by Freudian Oedipal theory of infantile sexua

SPECT findings in children with specific language impairment.

Findings from 99mTc-HMPAO SPECT measurements at rest in a group of 19 school-age children with specific language impairment (SLI) were compared to a group of 12 children with attention-deficit hyperactivity disorder (ADHD). The regional cerebral blood flow (CBF) distributions were different in the two groups. Children with SLI showed significantly lower CBF values in the right parietal region and

Liquid-target laser-plasma source for X-ray lithography

We describe a compact and practically debris-free laser-plasma x-ray source suitable for proximity lithography. The source is based on a microscopic fluorocarbon continuous liquid jet droplet target, generating high-brightness lambda=1.2-1.7 nm x-ray emission with similar to 5% conversion efficiency. This target type has the advantages of producing only negligible amounts of debris, and being rege

Rho-guanine nucleotide exchange factors during development: Force is nothing without control.

The development of multicellular organisms is associated with extensive rearrangements of tissues and cell sheets. The driving force for these rearrangements is generated mostly by the actin cytoskeleton. In order to permit the reproducible development of a specific body plan, dynamic reorganization of the actin cytoskeleton must be precisely coordinated in space and time. GTP-exchange factors tha

A prospective evaluation of the diagnostic value of video capsule endoscopy in patients initially classified as irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome (IBS) is characterized by chronic gastrointestinal dysfunction in the absence of detectable organic disease. The recently developed technique, video capsule endoscopy (CE), has been shown to be much more sensitive than traditional enterography in detecting mucosal changes in the small intestine. This study was performed to see if any earlier, not detectable by

Early development of retinal subtypes in long-term cultures of human embryonic retina.

Purpose: To study early signs of neuronal and glial differentiation in the human embryonic retina. Materials and Methods: 6.5-to 8-week-old human embryos were obtained from elective abortions. The neuroretinas were kept in culture as full-thickness sheets for 7-42 days. Results: The control retinas consisted of a neuroblast cell layer and a thin marginal zone. Most explants displayed presence of r

Neighborhood deprivation and inequities in coronary heart disease among patients with diabetes mellitus: A multilevel study of 334,000 patients.

We used multilevel models to investigate whether the odds of coronary heart disease (CHD) is higher in patients with diabetes mellitus (DM) living in deprived neighborhoods versus those living in wealthy neighborhoods. The Swedish nationwide prescription register was used to identify 334,000 patients aged 30 years and older with DM. The OR of CHD was significantly higher among patients with DM liv

The value of debridement and Vacuum-Assisted Closure (V.A.C.) Therapy in diabetic foot ulcers.

BACKGROUND: Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatme

The first successful eccentric correction

This paper presents a new procedure for assessing off-axis refractive errors; in this case, oblique astigmatism. By using photorefraction to objectively measure the off-axis refraction, it is possible to identify and provide eccentric correction that results in better image quality for the preferred retinal location (PRL) or the trained retinal location (TRL). This paper describes the case of a 56

Upper-body morbidity after breast cancer: incidence and evidence for evaluation, prevention, and management within a prospective surveillance model of care.

The purpose of this paper is to review the incidence of upper-body morbidity (arm and breast symptoms, impairments, and lymphedema), methods for diagnosis, and prevention and treatment strategies. It was also the purpose to highlight the evidence base for integration of prospective surveillance for upper-body morbidity within standard clinical care of women with breast cancer. Between 10% and 64%

Clinicopathological concordance in dementia diagnostics.

OBJECTIVE: Accurate distinction between dementia subtypes is important for patient care and pharmacological treatment. Continuing systematic comparisons of clinical and neuropathological dementia diagnoses may provide a basis for further improvement of the diagnostic procedure. The purpose of this study was to investigate concordance between clinical dementia diagnosis and neuropathological findin

Blood transfusion after cardiac surgery: is it the patient or the transfusion that carries the risk?

Background: The transfusion of red blood cells (RBCs) after cardiac surgery has been associated with increased long-term mortality. This study reexamines this hypothesis by including pre-operative hemoglobin (Hb) levels and renal function in the analysis. Methods: A retrospective single-center study was performed including 5261 coronary artery bypass grafting (CABG) patients in a Cox proportional

Role of neutrophils in the activation of trypsinogen in severe acute pancreatitis.

The relationship between inflammation and proteolytic activation in pancreatitis is an unresolved issue in pancreatology. The purpose of this study was to define the influence of neutrophils on trypsinogen activation in severe AP. Pancreatitis was induced by infusion of taurocholate into the pancreatic duct in C57BL/6 mice. For neutrophil depletion, an anti-Gr-1 antibody was administered before pa
