Perioperative considerations in infantile neuroaxonal dystrophy
Summary Infantile neuroaxonal dystrophy is a rare neurological disorder that is universally fatal with life expectancy under 10 years. A 10‐year‐old boy with infantile neuroaxonal dystrophy and severe neuromuscular scoliosis underwent posterior spinal fusion following halo traction. He was successfully extubated to bilevel positive airway pressure on postoperative day 3 and discharged home on postoperative day 11. Infantile neuroaxonal dystrophy presents several perioperative challenges including concerns for difficult intubation and respiratory dysfunction. (Source: Pediatric Anesthesia)

Hydroxysafflor Yellow A Alleviates Lipopolysaccharide-Induced Acute Respiratory Distress Syndrome in Mice.
Abstract Hydroxysafflor yellow A (HSYA) is an effective ingredient of the Chinese herb Carthamus tinctorius L. The present study investigated the protective effect of HSYA on lipopolysaccharide (LPS)-induced acute respiratory distress syndrome in mice, and the underlying mechanisms involved. HSYA (14, 28, 56 mg/kg) was intraperitoneally injected to mice once daily from day 1 to 10 after LPS administration. HSYA attenuated the body weight loss, the augmented left index and the increase of pathologic changes in pulmonary inflammation caused by LPS. Treatment with HSYA also alleviated increased expressions of tumor...

TC2 C776G polymorphism studies in patients with oral cancer in the Polish population.
Authors: Malinowska K, Morawiec-Sztandera A, Majsterek I, Kaczmarczyk D Abstract The first signs of oral cancer may resemble developing infections in the mucous membranes, with throat cancer symptoms being similar to those of upper respiratory tract infections. This greatly hinders rapid diagnosis and treatment. Better knowledge of the changes occurring in the metabolism of folic acid can help in understanding the carcinogenesis affecting DNA methylation and genome stability. Polymorphisms in genes encoding enzymes involved in this pathway may influence enzyme activity and thereby interfere with the concentrations ...

Complete mesocolic excision an assessment of feasibility and outcome.
Authors: Bertelsen CA Abstract Surgery is the most important factor for radical treatment of colon cancer, and the long-term prognosis can be improved by improving the surgical treatment without increased risk of perioperative mortality. Complete mesocolic excision (CME), in which more extensive lymph node (LN) dissection is performed, has been shown in single-centre studies with historical controls to be associated with better oncological outcome. However, better evidence is needed. The main purpose of this PhD thesis was to investigate whether CME could be implemented in a colorectal surgical department in Denmar...

The Safety of Laryngeal Mask Airway-Assisted Bronchoscopy versus Standard Nasal Bronchoscopy
Background: The use of laryngeal mask airway (LMA) for fiberoptic bronchoscopy was first described in 1982. The LMA was found to be beneficial in operator view, flexibility, and also in maintaining stable oxygen saturation. Despite its advantages, the use of LMA has not become widespread.Objective: The aim of this paper was to evaluate the safety of LMA-assisted bronchoscopy compared to standard nasal bronchoscopy.Methods: We conducted a prospective randomized trial. The study group included 105 patients prospectively randomized to undergo either LMA-assisted (53 patients) or standard nasal bronchoscopy (52 patients). The ...

Children in Greenland: disease patterns and contacts to the health care system.
Conclusions In this first study of its kind, the health care contact pattern in Greenlandic children showed a relatively high hospitalisation rate and duration per admission, and a low primary health care contact rate. The overall contact rate and disease pattern resembled those in Denmark, except for tuberculosis screening. Adherence to the vaccination programme was low. These findings may be helpful for the organisation and dimensioning of the Greenlandic health care system for children.

Chronic obstructive pulmonary disease and atrial fibrillation: An unknown relationship.
Abstract Chronic obstructive pulmonary disease (COPD) is independently associated with atrial fibrillation (AF). Decreased oxygenation, hypercapnia, pulmonary hypertension, diastolic dysfunction, oxidative stress, inflammation, changes in atrial size by altered respiratory physiology, increased arrhythmogenicity from nonpulmonary vein foci commonly located in the right atrium, and respiratory drugs have been implicated in the pathogenesis of AF in COPD. The understanding of the relationship between COPD and AF is of particular importance, as the presence of the arrhythmia has significant impact on mortality, espec...

Suplatast tosilate protects the lung against hyperoxic lung injury by scavenging hydroxyl radicals.
Abstract Prolonged exposure to hyperoxia produces extraordinary amounts of reactive oxygen species (ROS) in the lung and causes hyperoxic lung injury. Although supraphysiological oxygen is routinely administered for the management of respiratory failure, there is no effective strategy to prevent hyperoxic lung injury. In our previous study, we showed that suplatast tosilate, an asthma drug that inhibits T helper 2 (Th2) cytokines, ameliorated bleomycin-induced lung injury and fibrosis through Th2-independent mechanisms. Because bleomycin also generates ROS, we hypothesized that suplatast tosilate might have antiox...

Forensic Considerations in Cases of Myotonic Dystrophy at Autopsy.
Abstract Myotonic dystrophy (DM) is a chronic, slowly progressive, autosomal-dominant disorder with delayed muscle relaxation after contraction, distal skeletal muscle weakness, and atrophy. It has a reduced life expectancy due predominantly to respiratory failure or sudden cardiac death. The mortality rate is approximately 7.3 times greater than the general population with a mean age at death of 53 years. Degeneration of the cardiac conduction system causes atrioventricular block, arrhythmias, and ventricular failure. A case of sudden death in a 44-year-old woman with DM type 1 is reported to demonstrate an alter...

Immunoglobulin (Ig)M antibodies to proteinase 3 in granulomatosis with polyangiitis and microscopic polyangiitis
Summary Anti‐neutrophil cytoplasmic antibodies (ANCA) appear to play an important role in the pathogenesis of ANCA‐associated vasculitis (AAV). However, ANCA alone are not sufficient to generate disease, and some evidence suggests that infectious triggers may serve as inciting events for AAV disease activity. Antibodies of the immunoglobulin (Ig)M isotype often serve as markers of recent infection, and IgM ANCA have been identified previously in patients with AAV, although the frequency and clinical relevance of IgM ANCA is not well established. We sought to characterize IgM ANCA more clearly by creating a novel enzyme...

Near-fatal Anorexia Nervosa in a Middle-aged Woman.

The management of this complex disease requires a team approach, and full recovery occurs only in 50% of patients. Endocrine and metabolic complications are commonly observed, the latter of which may even be life-threatening, and require prompt and proper management. Infections, albeit reported, are not usually a major clinical problem in these patients. We herein report the case of a seve...
