ABSTRACT
BACKGROUND: The incidence of non melanoma skin cancers is closely correlated with age. The aim of this prospective study was to evaluate the prevalence of undiagnosed skin cancers among patients hospitalized in rehabilitation and long-term care units in a geriatric hospital. PATIENTS AND METHODS: All the patients, resident in four rehabilitation and long-term care units and for whom no dermatological advice had been given, were systematically examined by a dermatologist. Clinical data included patient age at the time of the study, gender, relevant historical information, skin phototype and description of the cutaneous lesions. Biopsies were performed for all lesions of suspicious appearance. RESULTS: Three hundred and six patients (79.4% women and 20.6% men aged from 55 to 103 years) were included in the study. Among all the patients, 69.3% were hospitalized for more than one year. Skin phototype was clear for 93.5% of the patients. Thirty-two out of 306 patients (10.5%) presented 42 suspicious lesions and these were diagnosed by histological examination as 16 basal-cell carcinomas, seven squamous cell-carcinomas and two in situ melanomas. Skin cancers were localised on the head and neck in 80% of cases. The prevalence of patients with skin cancers was 5.6% in this population. CONCLUSION: The prevalence of skin cancers among patients hospitalized in geriatric hospitals justifies improved training of geriatricians regarding early recognition and dermatological assessment of cutaneous tumours.

The article presents a case of spontaneous twisting and necrosis of the greater omentum in a 27-year old multipara. The pregnancy was terminated by Cesarean section, the necrotic omentum was removed. The authors did not find the reason for the disease.

The technique of scanning tunneling microscopy has been applied to topographic mapping of two optical surfaces: a ruled grating replica and a diamond-turned gold mirror. We have demonstrated the ability of the scanning tunneling microscope to measure surface topography of a ruled-grating replica over an area of 2 microm x 2 microm. Furthermore, surface structure on a diamond-turned gold mirror was observed that could not be detected by any other type of surface-sensitive microscope. These measurements yield information necessary for gaining a complete understanding of the diamond-turning process.
