The Workplace Health Promotion (WHP) programme in an Italian University Hospital.

INTRODUCTION: Description of the lifestyles of employees of the Siena University Hospital (Azienda Ospedaliera Universitaria Senese: AOUS), as assessed through a Workplace Health Promotion (WHP) project in the two-year period 2017-18; assessment of possible short-term effects of integrated health promotion interventions in the workplace, within the framework of the Tuscany WHP network, as applied in the AOUS and involving about 1,000 workers. METHODS: A cross-sectional study and a pre-post evaluation of data collected by means of anonymous questionnaires in two phases: before the beginning of the programme and after 12 months. RESULTS: Twelve months after the start of the programme regarding diet (consumption of fruit and vegetables) and physical activity, the positive effects that emerged were not statistically significant. No differences were observed between gender or professional categories. The employees' perception of the programme was satisfactory. CONCLUSIONS: Albeit within the methodological limits of the assessment, the results showed that the diffusion of some major risk factors for chronic diseases had not decreased after 12 months' exposure to the programme. However, monitoring of these risk factors needs to be continued over a longer period, in order to detect the appearance of the expected changes in the long term. Moreover, it is essential to continue monitoring by sex and professional category, in order to pick out any differences and, if possible, take remedial actions. Further studies, in collaboration with the pertinent physicians, are desirable, since integrating data collected during health surveillance with a limited set of indicators of general risk factors may help to promptly identify possible health needs among employees.

[Ultrasonography in acute diverticulitis of the colon: semiologic features]. / L'ecografia nella diverticolite acuta del colon: aspetti semeiologici.

To assess the ultrasonographic (US) patterns of acute colonic diverticulitis, we prospectively examined 21 patients. US was performed in all of them, CT in 13/21, contrast enema in 18/21 and endoscopy in 2/21 patients. US follow-up was carried out in 15/17 patients managed with conservative treatment. To analyze the US patterns of simple diverticula, we carried out an in vitro study of two surgical specimens with simple colonic diverticulosis. Wall thickening was seen in 21/21 cases, diverticula in 19/21, changes in pericolic fat in 11/21, local tenderness on gradual compression in 19/21 and changes in peristaltic activity in 21/21 cases. Even though diverticula may appear differently, we found 4 main patterns: round or linear hyperechoic pericolic outpouchings with no definite wall, usually with shadowing or reverberation artifacts (pattern 1), a saccular focus with a well-defined wall and various contents (pattern 2), a tubular structure with no content but with central linear echoes (pattern 3), and a flask-like or arrowhead-like hypoechoic focus (pattern 4). Patterns 1, 2 and 3 were shown in inflamed colic segments and in unaffected adjacent tracts, both in the acute phase and at follow-up, with no relevant morphological changes. In contrast, pattern 4 was observed in 10/19 patients, always in the acute phase and in affected colic tracts. The follow-up showed a decrease in size in 3 cases and a change to patterns 1, 2 or 3 in 7 patients. The authors believe pattern 4 to represent inflamed diverticula, while patterns 1, 2 and 3 indicate simple diverticula. Moreover the detection of diverticula and thickened wall segments does not necessarily indicate diverticulitis: thus, the diagnosis of this condition must rely on the presence of several signs, the most specific of which were, in our series, the flask-like and arrowhead-like patterns, presumptively expressing peridiverticular abscess.

[Radiological aspects of intestinal lipomas]. / Aspetti radiologici dei lipomi intestinali.

The radiological detection of intestinal lipomas is not unusual; however, in-depth studies of their radiological features have never been carried out, so far. Eighteen cases of intestinal lipoma were observed, out of different clinical histories. Through a careful survey of these cases, the authors describe the semiological characteristics of the lipomas, which were studied with radiographic contrast examinations of the small intestine and colon. In most cases the characteristics of the mass and--when present--the even more revealing features of its pedicle allowed the identification of such expansive lesions as lipomas. In some lesions detected by means of conventional methods CT proved extremely useful in diagnosing the nature of the lipomas. Such a diagnosis is extremely useful for it allows extensive surgery to be avoided and replaced with less extensive procedures--e.g. endoscopic removal of the lesion, or no specific treatment at all.

[The syndrome of solitary rectal ulcer. Problems of radiologic diagnosis]. / La sindrome dell'ulcera solitaria del retto. Problemi di diagnosi radiologica.

The authors review 7 cases of syndrome of the solitary ulcer of the rectum, examined with barium enema. The radiological signs of this syndrome, rarely described in literature, are compared with those observed in this series.
