BACKGROUND: Standard diagnostic testing for HIV infection has traditionally relied on a high sensitivity HIV antibody screening test using an enzyme-linked immunosorbent assay (ELISA) followed by a high specificity antibody confirmatory test such as a Western Blot. Recently several of the screening assays have been enhanced with an ability to identify p24 antigen thereby narrowing the diagnostic window. OBJECTIVES: To explore the implications of enhanced HIV screening methods that may be leading to HIV misdiagnoses...

BACKGROUND: Pediatric oncologists are often faced with situations in which parents or guardians refuse recommended treatment for curable childhood cancer. Deciding how to proceed in such situations is an ethical dilemma. The aim of this article is to consider optimal approaches when parents are strongly against oncological treatment, potentially compromising their childrens rights for health care and to the chance for cure. CASES: In this paper, we report two cases of treatment refusal from our department and the impact of such decisions on the children themselves...

BACKGROUND: The standard postsurgical options for low-grade gliomas include watchful waiting or radiotherapy depending on the risk factors for recurrence. The use of chemotherapy for the treatment of this disease is generally controversial, although the recently published results of the first of two large randomized phase III clinical trials (RTOG 9802 a EORTC 22033-26033), focusing on the evaluation of chemotherapy for the upfront treatment of newly diagnosed low-grade gliomas, are reassuring in this respect...

#6
Kevin Woo, Jennifer Kasaboski
Prevention and treatment of pressure injuries (PI) is a standard benchmark for quality of care, performance, risk reduction, and patient safety. Foam dressings are designed to wick away a large volume of exudate with minimal lateral movement to prevent periwound skin maceration; this renders foam dressings a popular choice for the treatment of chronic wounds with high to moderate amounts of exudate. In addition, multi-layer foam dressings may have added benefits to alleviate pressure and minimize shear as the dressing materials slide against each other...

INTRODUCTION: The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. Recently, over-sewing has been proposed as a cost-effective and helpful method for reinforcing the staple line. The purpose of this study was to report our initial experience with LSG comparing over-sewing over the entire staple line with the upper-third staple line. MATERIALS AND METHODS: All obese patients seen at Negrar Sacro Cuore, Don Calabria Hospital were entered into our prospective database and were retrospectively evaluated...

BACKGROUND: Prior studies have observed similar health-related quality of life (HRQL) in revisions and nonrevision (NR) patients following adult spinal deformity (ASD) correction. However, a novel comparison approach may allow better comparisons in spine outcomes groups. OBJECTIVE: To determine if ASD revisions for radiographic and implant-related complications undergo a different recovery than NR patients. METHODS: Inclusion: ASD patients with complete HRQL (Oswestry Disability Index, Short-Form-36 version 2 (SF-36), Scoliosis Research Society [SRS]-22) at baseline, 6 wk, 1 yr, 2 yr...

Aims: To test the hypothesis that patients with ischaemic cardiomyopathy (ICM) and non-ischaemic cardiomyopathy (NICM) have different torsion and strain parameters, and compare to healthy, age-matched controls. VINDICATE investigated efficacy of high-dose vitamin D on patients with heart failure (HF) secondary to left ventricular (LV) systolic dysfunction of any aetiology. It is important to differentiate ICM and NICM as treatment and prognosis varies significantly. Cardiovascular magnetic resonance (CMR) reliably determines aetiology of HF and tissue tagging techniques are recognized as the reference standard measures of strain and torsion...

Background: Inhaled tobramycin is important in the treatment of Pseudomonas aeruginosa ( Pa ) infections in cystic fibrosis (CF). However, despite its use it fails to attenuate the clinical progression of CF lung disease. The bactericidal efficacy of tobramycin is known to be concentration-dependent and hence changing the dosing regimen from a twice-daily (q12h) inhalation to a once-daily (q24h) inhaled double dose could improve treatment outcomes. Objectives: To predict local concentrations of nebulized tobramycin in the airways of patients with CF, delivered with the small airway-targeting Akita ® system or standard PARI-LC ® Plus system, with different inspiratory flow profiles...
