Sensory Profile of Children and Adolescents with Autism Spectrum Disorder and Tip-Toe Behavior: Results of an Observational Pilot Study.

Atypical sensory processing is frequently reported in persons with autism spectrum disorders (ASD), and it is one of the described diagnostic criteria for ASD. There is also mounting literature supporting the presence of motor impairments in individuals with ASD. Among these motor signs, tip-toe behavior (TTB) is a possible clinical finding, but its etiology is not clearly understood.

The use of polytetrafluoroethylene to facilitate the vascular access in recurrent melanoma to limbs.

Introduction: Melanoma with recurrent loco-regional metastases to limbs often makes difficult a second surgical approach because of the adhesions affecting the vascular access. Our aim was to evaluate whether the placement of a polytetrafluoroethylene (PTFE) membrane around vessels might facilitate a surgical re-approach.

Presentation Of Case: We reported a case of a 64-year-old male with a melanoma on the left foot who developed in transit metastases after LND.

[Volvolus in an adult patient due to intestinal malrotation. Case report and review of literature].

Intestinal malrotation is a rare cause of bowel obstruction in adults and it could create a perplexing situation for surgeons not familiar with this pediatric pathology. Symptomatic patients present either acutely with bowel obstruction and intestinal ischemia with a midgut or cecal volvolus, or chronically with vague abdominal pain. Several modalities can be used to describe the intestinal abnormality such as barium X-ray, computer tomography scans, angiography and sometimes also the explorative laparotomy.

Comparison of Allevyn Adhesive and Biatain Adhesive in the management of pressure ulcers.

Objective: The primary objective was to assess dressing delamination and the ensuing potential consequences during wear and/or removal, as well as the effect of residue remaining in the ulcer following foam breakdown.

Method: In this prospective multicentre study, 32 patients with a grade II or III pressure ulcer were randomised to receive either Allevyn Adhesive or Biatain Adhesive dressing. The performance of the dressings was assessed over seven dressing changes or a maximum of six weeks.

Cell proliferation, migration and CAM-dependent neurite outgrowth as developmental in vitro endpoints for screening teratogenic potential: Application to valproic acid and related analogues of varying potency.

The in vivo teratogenic potential of valproic acid (VPA) and related teratogenic and non-teratogenic analogues has been correlated with their effects on specific in vitro endpoints of cell proliferation, migration and CAM-dependent neurite outgrowth, as these events are common to crucial epochs of development. The (+/-)-2-n-propyl-4-pentynoic acid [(+/-)-4-yn-VPA] and S-2-n-propyl-4-pentynoic acid [S(-)-4-yn-VPA] analogues increased the incidence of neural tube defects in mouse embryos exposed to a single dose, whereas the E-2-n-propyl-2-pentenoic acid (E-2-en-VPA) analogue and R-2-n-propyl-4-pentynoic acid [R( + )-4-yn-VPA] enantiomer were without effect. VPA and related analogues tested exerted comparable G1 phase antiproliferative effects in C6 glioma and limb bud cells in a dose range of 0-3 mM; however, their relative potency did not correlate with in vivo teratogenicity.
