Randomized Double-Blind Crossover Study for Evaluating a Probiotic Mixture on Gastrointestinal and Behavioral Symptoms of Autistic Children.

Autism spectrum disorders (ASDs) represent a diagnostic challenge with a still partially uncertain etiology, in which genetic and environmental factors have now been assessed. Among the hypotheses underlying the involvement of biological and environmental factors, the gut-brain axis is of particular interest in autism spectrum disorders. Several studies have highlighted the related incidence of particular gastrointestinal symptoms (GISs) in children suffering from ASDs.

Students, Severe Illness, and Palliative Care: Results From a Pilot Study on a School-Based Intervention.

This study was aimed at piloting a school-based intervention on severe illness, within a project focused on spreading knowledge of palliative care among high school students (phases 0-2 Medical Research Council Framework). The intervention entailed the screening of a topic-related movie, 2 classroom meetings, and the development of a class-based multimedia production. Five classes from 5 high schools participated in this study, and a before-after evaluation was used to assess intervention feasibility and impact.

Prulifloxacin vs fosfomycin for prophylaxis in female patients with recurrent UTIs: a non-inferiority trial.

Introduction And Hypothesis: This multicentre, randomised, non-blinded, parallel group study is designed to assess the null hypothesis that a 3-month prophylactic schedule with fosfomycin is not inferior to prulifloxacin in reducing the number of urinary tract infection episodes during and after prophylaxis in female patients with recurrent urinary tract infections (rUTIs).

Methods: One hundred and fifty-two patients with rUTIs who were candidates for prophylaxis therapy were enrolled and randomised to prulifloxacin (group 1) or fosfomycin (group 2). The prophylaxis regimen included a single dose of fosfomycin (one 3-g cachet) per week, or a single dose (600 mg) of prulifloxacin (one tablet) a week for 12 weeks.

Role of phytotherapy associated with antibiotic prophylaxis in female patients with recurrent urinary tract infections.

Objective: Aim of this study is to evaluate the efficacy of a phytotherapic which includes Solidago, Orthosiphon and Birch extract (Cistimev®) in association with antibiotic prophylaxis in female patients affected by recurrent urinary tract infections (UTIr).

Materials And Methods: Patients affected by UTIr older than 18 years started a 3-months antibiotic prophylaxis (Prulifloxacin 600 mg, 1 cps/week or Phosphomicyn 1 cachet/week) according to antibiogram after urine culture. The patients were divided in 2 groups: Group A: antibiotic prophylaxis plus phytotherapy (1 cps/die for 3 months) and Group B: antibiotic prophylaxis alone.

[Immunological development in asymptomatic HIV infected children].

In HIV infected children, CD45+CD4+ T lymph. reconstitution has been related to efficient thymopoiesis. Because human thymus undergoes spontaneous involution at a relatively young age, institution of antiretroviral therapy early in the course of infection has been recommended.

[The evaluation of the physical characteristics of a volumetric computer tomograph].

Spiral or volumetric computed tomography (CT) is a new scanning technique which allows the scanning of body regions with a continuously rotating system based on the slip ring technology; the patient is also moved continuously, synchronously with data acquisition. The physical characteristics of spiral CT image acquisition were compared with those of conventional CT images. The modulation transfer function (MTF) has the same values for medium-resolution filters, but lower values for spiral CT for high-resolution and frequency-enhancement filters.

[Digital storage phosphor radiography. Doses and image quality].

Digital radiography (DR) based on storage phosphor technology is progressively replacing conventional screen-film system radiographic techniques (CR). However, many questions about image quality and dose reduction are still open. Thus, since DR spatial resolution is always lower than that of high quality screen-film images and image noise is conversely higher, for general radiography examinations especially, the signal-to-noise ratio is always lower with DR than with CR at the same dose level.

CT and chest radiography in the evaluation of adult respiratory distress syndrome.

CT is seldom employed in adult respiratory distress syndrome (ARDS), mostly due to problems in transporting and monitoring these severely ill patients. We reviewed the findings of 74 ARDS patients who underwent chest CT. Lung opacities were bilateral in almost all patients and dependent in most cases (86%).

[The detectability of osteoarticular lesions of the extremities on the television monitor].

The diagnostic accuracy of the light-box reading of conventional (film screen) radiographs of the extremities was compared with that of the same set of images displayed on a 1 k x 1 k interactive monitor after laser digitization. 389 alterations (23 nondisplaced fractures, 129 soft-tissue calcifications and 237 articular bone erosions), identified by two experienced radiologists on 66 conventional radiographs, were the reference standard. ROC statistical analysis was performed on 1,556 observations expressed by four readers.

[Detection of small bone lesions with digital radiography using storage phosphors].

To date, the skeletal imaging capabilities of digital radiography with storage phosphors have been poorly investigated, and the diagnostic accuracy of this technique has not been thoroughly assessed. To evaluate the performance of storage phosphor digital radiography we compared 66 conventional and 66 digital radiographs of small abnormalities of the extremities (fractures, erosions, calcifications). Conventional images were obtained with a low-speed screen-film system while digital ones were acquired with high-resolution (5 lp/mm max) phosphors and laser-printed on a 8" x 10" film.

[Digital radiography with phosphorus memory: verification of the centering of the patient in high-energy radiotherapy].

A digital radiographic system using storage phosphor detectors was employed in order to verify radiotherapy treatments with high energy photon beams (60Co-18 MV X-rays). The wide range linearity of the detectors and also the possibility of digital image post-processing allowed portal films to be obtained with sufficient contrast in all treatment techniques, particularly in the case of mantle fields. The use of digital radiography may become an easy and valuable procedure for therapy verification.

A radiologic study by CT scan of pineal size in cancer patients: correlation to melatonin blood levels.

Alterations in size of the pineal body and melatonin secretion have been observed in cancer patients. The present study was carried out to evaluate pineal dimensions in a group of cancer patients and their relation to melatonin blood levels. The study included 70 oncologic patients.

[Digital radiography in urography].

The clinical utility was evaluated of a computed radiographic system in urography. The system (FCR 101, Philips Medical Systems, Inc., Shelton, CT) is based on a photo-stimulatable phosphor screen (imaging plate) for X-ray image detection and storage.

[Digital radiography using light-emitting detectors. Operative principles and characteristics of images].

This paper briefly describes the technical features of a digital radiographic system based on the principle of scanning laser stimulated luminescence. Such aspects as the physics of the stimulable phosphor detector are dealt with, and image acquisition, processing, and hard-copy output. Automatic analysis of pixel histograms is described, in a qualitative way, together with contrast modifications and spatial filtering.

[Digital radiography with photo-emitting detectors. Technical note].

A specification on a digital radiography system which has been recently installed, based on the principle of scanning laser stimulated luminescence, is explained in short. We have just verified the possibility, among the many potential advantages, to produce good images at the lowest doses and insensitive to over and under exposure.

[Chondropathy of the patella. Clinico-radiologic study].

Totally 165 cases of chondromalacia patellae, taken from a series of 240 patients, are presented. The cause of the chondromalacia lies in imbalances, displacements, dysplasias of patellae and in femoro-tibial axial deviations. Overload is the constant intermediary between the different starting causes and the same final result.
