[The participatory approach to injury prevention appeared to be an useful tool of safety education and ergonomic improvement]. / Ergonomia partecipativa come strumento per la vigilanza sugli infortuni.

Participatory techniques have been adopted in vigilance of Civitavecchia's port activities, in order to control and remove injury causes. Injuries were studied by small participatory groups of port workers. As an example, seafastening operations were analyzed. The project team encouraged the workers to design ergonomic measures, or to modify work organization. Workers made suggestions and presented their points of view, that were reported to management for implementation.

[Radiological mass screening in pulmonary cancer. Is it useful in improving the prognosis?]. / L'esame radiologico di massa nel carcinoma polmonare. E utile per migliorare la prognosi?

The diagnostic usefulness and practical possibilities of mass X-ray screening in lung cancer is examined. On the basis of the literature and personal experience, the conclusion is cautiously pessimistic, in agreement with what has recently been stated by Lemoine, Corda and others.

[Multiple hepatic abscesses: a pediatric case report]. / Ascessi epatici multipli: descrizione di un caso in età pediatrica.

The Authors describe the case of an immunologically healthy 14 year old boy presenting a hepatic infection with multiple abscesses. This case is of particular interest because of its rarity in Pediatrics. Probable etiologies, pathogenic mechanisms and treatments are discussed. The Authors underline the usefulness of ultrasonography as a diagnostic tool and as a non-invasive means of following the course of the disease.

[Screening of urologic pathology in newborns with prenatal and postnatal echography]. / Screening delle patologie urologiche nel neonato con ecografia prenatale e postnatale.

We compared the results, by prenatal ultrasonography, effected on 2592 foetus at the 15th-25th-35th weeks of gestation with the ones, made by postnatal ultrasonography, effected the 5th day of life on 2539 infants born from pregnancies previously monitored. We considered the obstructive and not obstructive malformations. The prenatal ultrasonography put in evidence 19 cases of urological pathology, which is 0.75%. The postnatal research established the truth of 14 cases, which is 0.55%; 7 cases underwent a precocious surgical operation. Percentage of positive false is 0.2%. The postnatal ultrasonography made evident 30 cases which can be considered pathological: 25 uropathy obstructive cases and 5 uropathy not-obstructive cases; 3 of them underwent precocious surgical operation. The result is 44 pathological cases (1.74% of infants). We also considered an heterogeneous group of non-nephro-urological anomalies (0.47%), a casual medical report of this research; in particular, 10 cases of surrenal hematoma and 1 case of neuroblastoma. The Authors remark that it's useful to complete the prenatal ultrasonographic research with another postnatal ultrasonographic research, particularly in the nephro-urological pathology; and they hope this system can be much more diffuse.

Role of magnetic resonance imaging in the staging of gastrointestinal neoplasms.

A concise review is presented of the current applications and techniques of magnetic resonance imaging (MRI) in the field of diagnostic imaging of oncologic disease of the gastrointestinal tract, with a summary of the diagnostic possibilities of MRI in the various types of tumor pathology of the gastrointestinal tract. We conclude with a review of the specific situations in which MRI presents distinct advantages over other diagnostic imaging methods (such as computed tomography and ultrasound).

[Laryngeal malignant schwannoma in a 9-year-old boy: report of a clinical case]. / Schwannoma maligno della laringe in un bambino di 9 anni: descrizione di un caso clinico.

A case of malignant schwannoma of the larynx in a 9 year old boy is reported. The lesion recurred 29 months later with the same histological pattern. The malignant peripheral nerve sheath tumours of the larynx are rare and are almost exceptional in paediatric age. The Authors discuss the main differential diagnosis of spindle cell paediatric tumors of the laryngeal region.
