Visual acuity and contrast sensitivity screening with a new iPad application

2016

We present a new iPad application (app) for a fast assessment of Visual Acuity (VA) and Contrast Sensitivity (CS) whose reliability and agreement was evaluated versus a commercial screening device (Optec 6500). The measurement of VA was programmed in the app in accordance with the Amblyopia Treatment Study protocol. The CS was measured with sinusoidal gratings of four different spatial frequencies: 3, 6, 12 and 18 cpd at the same contrast values of the Functional Acuity Contrast Test (FACT) included in the Optec 6500. Forty-five healthy subjects with monocular corrected visual acuities better than 0.2 logMAR participated in the agreement study. Bland-Altman analyses were performed to assess…

Vitellogenesis inhibition in Oncopeltus fasciatus females (Heteroptera: Lygaeidae) exposed to cadmium

2005

Abstract Newly moulted females of the insect Oncopeltus fasciatus were exposed to cadmium (Cd) dissolved in the drinking water (50–400 mg l −1 Cd) for 5 days. Cd exposure delayed ovarian maturation and inhibited egg production. Exposure to Cd, moreover, decreased hemolymph levels of the two major vitellogenin polypeptides of O. fasciatus , VG1 and VG2, in a concentration-dependent way, probably by a reduction in their synthesis. The ovarian levels of VG1 and VG2 were also decreased in Cd-exposed females. It was next investigated whether Cd effects might be a consequence of the endocrine disruption of vitellogenin synthesis, which is controlled by juvenile hormone (JH). JH replacement therap…

Correlation of Vertebral Absolute Axial Rotations in CAD 3D Models of Adolescent Idiopathic Scoliosis Non-Invasively Diagnosed

2019

This paper presents preliminary results on non-invasive optical diagnosis of patient with adolescent idiopathic scoliosis (AIS) with recently developed tool ScolioSIM. This tool generates intrinsic and extrinsic indicators of the spinal deformity and 3D CAD (Computer-aided Design) deformity model based only on a digitalized dorsal surface of the examined patient. Our primary focus in this paper are absolute axial rotations (AAR) of each vertebra in AIS patients and their correlations. Clinical relevance of this research is high, as we intend to avoid traditional methods which rely on highly complicated reading and measuring of AARs on planar x-ray films, as these methods involve ionizing ra…

Global health training in paediatric residency programs: the Italian experience

2015

Osservatorio Nazionale Specializzandi Pediatria (ONSP) is an Italian association of residents in paediatrics, and one of its interests is to support paediatric training in developing countries. In 2014, for this purpose, ONSP performed a survey with the aim of describing interest, participation, resources, and obstacles of residents who are involved in global health training within paediatric residency programs. Once the final data were known, an informative brochure was produced for publicizing the results of this survey and the projects that Italian Pediatric Schools have activated in developing countries. 35 of 38 paediatric residency schools (92%) participated in the survey. 67% of them…

Inferior mesenteric vein as initial landmark for laparoscopic medial to lateral dissection of descending colon - a video vignette

2017

The root of the inferior mesenteric artery is an important area where autonomic nerves are close by, the dissection can be hard and laborious in order to avoid nerve damage; and the separation of mesocolon and retroperitoneum in this area can sometimes be difficult. The inferior mesenteric vein dissection is an alternative option as the first step during medial to lateral approach of laparoscopic left mesocolon mobilisation, as we have shown in this video based on two real cases and two anatomical cadaveric dissection.

Predictors of individual adaptation to high-volume or high-intensity endurance training in recreational endurance runners

2015

The aim of this study was to investigate factors that can predict individual adaptation to high-volume or high-intensity endurance training. After the first 8-week preparation period, 37 recreational endurance runners were matched into the high-volume training group (HVT) and high-intensity training group (HIT). During the next 8-week training period, HVT increased their running training volume and HIT increased training intensity. Endurance performance characteristics, heart rate variability (HRV), and serum hormone concentrations were measured before and after the training periods. While HIT improved peak treadmill running speed (RSpeak ) 3.1 ± 2.8% (P < 0.001), no significant changes occ…

2014

It has been claimed that endoscopic calcaneoplasty offers some advantages over open techniques in the surgical treatment of Haglund’s deformity due to reduced postoperative complications like stiffness and pain. Bony over-resection places patients at risk of these complications. The resulting question with regard to the quantitative differences of the extent of the bone removed using these two techniques has not yet been answered. The purpose of the study was to determine the resection volume of calcaneal bone for open and endoscopic surgical techniques.
