Although exposure to indoor tanning has been established as a clear risk factor for skin cancer, sunbeds are still commonly used in Europe. Understanding the determinants of sunbed use in Europe is key to plan educational interventions, behavioural strategies and legislative measures, which should be tailored to subgroups with different risk profiles. Evidences show that the typical sunbed users in Europe are young-adult women, with intermediate skin type, a current employment and a medium/high socio-economic status.

Objective: This descriptive pilot study aimed at assessing the impact of art contemplation on patients' adaptation to hospital confinement and the factors influencing this effect.

Study Design: Artistic photographs were hung on the walls of the ward. Two hundred and thirty-nine (239) consecutive non-bed-constrained patients who stayed in the ward for at least 3 days (original number enrolled in study were males/females: 148/96, age 19-89 years; 5 patients declined to fill out questionnaires) participated in the study.

Objective: Sleep disorders are common and may coexist with a variety of diseases, including epilepsy, with important implications for the clinical management of the latter. Sleep fragmentation and deprivation, and hypoxia associated to sleep disordered breathing (SDB) may contribute to the occurrence of seizures. On the other hand, antiepileptic drugs may worsen SDB by reducing the muscle tone of the upper airways, and increasing the arousal threshold.

Objectives And Methods: To perform a video-polygraphic analysis of 11 cataplectic attacks in a 39-year-old narcoleptic patient, correlating clinical manifestations with polygraphic findings. Polygraphic recordings monitored EEG, EMG activity from several cranial, trunk, upper and lower limbs muscles, eye movements, EKG, thoracic respiration.

Results: Eleven attacks were recorded, all of them lasting less than 1 min and ending with the fall of the patient to the ground.

A study comparing actigraphy and polysomnography in the detection of leg movements was performed in a group of 35 patients with sleep disorders. Visual scoring used epochs of 5-second duration, and in each epoch, electromyographic activity of tibialis anterior muscle was classified in eight types on the basis of its duration and amplitude. Activity levels of the actigraphic data were logged in 5-second intervals and stored in memory for computer retrieval.

Mastocytosis is a heterogeneous group of disorders characterized by abnormal growth and accumulation of mast cells in skin, bone marrow, bone, gastrointestinal tract, liver, spleen and lymph nodes. Today, regarding its biological features, mastocytosis (with or without myeloid accompanying disorders) is considered to be a hematologic disease. The classification proposed by Metcalfe in 1991 is the most useful in caring for patients with mastocytosis.

A case of a 64-year-old man with eccrine carcinoma arising from hand skin is reported. At the time of diagnosis he showed bilateral pneumonic metastases. Although the patient underwent two systemic chemotherapy lines, he showed further progressive disease of the lung.

Objective: To evaluate the patients' individual characteristics predictive of the degree of respiratory effort developed during obstructive sleep apneas (OSAs).

Design: Prospective consecutive sample, collection of clinical and polysomnographic data.

Setting: University teaching hospital.

We tested the hypothesis that the awake ventilatory response to hypoxia and hypercapnia may contribute to the variability of respiratory effort developed in response to upper airway obstruction in obstructive sleep apnea syndrome. The polygraphic recordings of 38 patients diagnosed as having obstructive sleep apnea on the basis of an apnea+hypopnea index greater than 10 were examined. All subjects received hypoxic and hypercapnic ventilatory tests the day before the nocturnal polysomnography.

Apneas generally reappear in patients with obstructive sleep apnea (OSA) when treatment with continuous positive airway pressure (CPAP) is interrupted. However, a single-night treatment interruption may be associated with a lesser severity of sleep apneas than before treatment. We hypothesized that this decrease in severity of sleep apneas reflects changes in the respiratory response to upper airway obstruction.

The authors describe five consecutive patients with testicular non Hodgkin lymphoma, evaluate the clinical and histological characteristics and underline the importance of a chemotherapy approach both at diagnosis and at relapse. A review of the literature is carried on and particularly about the prognostic factors, the correlation with Ebstein Barr virus and the more recent integrated therapeutical approaches.

To test the hypothesis that respiratory effort during obstructive apneas contributes, together with hypoxemia and sleep fragmentation, to excessive daytime sleepiness, we investigated the relationship between daytime sleepiness and polysomnographic variables in 44 patients with obstructive sleep apnea (OSA). In all patients, daytime sleep propensity was assessed by an 11-item standardized self-questionnaire yielding a sleepiness score and by a modified sleep latency test yielding a mean sleep latency. Respiratory effort during apneas was evaluated by measuring esophageal pressure swings using an esophageal balloon.

Daytime sleepiness is one of the major symptoms of obstructive sleep apnea. However, its definition raises problems, since it may be based on either subjective feeling (evaluated by means of questionnaires or analog visual scales), physiological drive or need (inferred by a sleep latency) or on the concept of sleep propensity defined as the probability of falling asleep (measured by the occurrence of sleep in various circumstances of daily life). Data from the literature suggest that sleep fragmentation and hypoxemia, both related to sleep apneas, cause daytime sleepiness.

We investigated whether cephalometric measurements, nocturnal indices of negative intrathoracic pressure, or the frequency of sleep-related breathing disorders were related to the level of effective continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA). We examined 22 OSA patients who underwent two consecutive polysomnographic recordings, the first for diagnosis and the second for CPAP titration. Cephalometric measurements, spirometric data, and blood-gas analysis results were available for all subjects.

The prognostic value of the location of the breakpoint on chromosome 22 in patients with Ph1+ chronic myeloid leukaemia (CML) is still controversial. We analysed both DNA rearrangement and transcript type in a new continuous series of CML patients. By Southern blotting analysis, we found that, out of 72 patients, 43 had a 5' rearrangement and 29 a 3' one, of the 43 5'-rearranged patients, 35 carried an a2b2 transcript and eight an a2b3 one, while, of the 29 patients rearranged in the 3' part of the M-BCR area, 26 had an a2b3 transcript, one had an a2b2 transcript and two carried both types of transcript.

Background: Some reports in the recent literature have shown that the site of molecular rearrangement within the M-BCR area may have a prognostic value in Ph1 + CML patients. A number of studies have, however, failed to demonstrate this finding. Here we report the molecular rearrangements of 107 patients and their clinical follow-up.

The objective of the present experiments was to determine whether prevention or moderation of exercise acidosis would influence arterial blood oxygenation and exercise capacity in hypoxia. The effect of administration of 0.3 M NaHCO3 (3 ml/100 g) on maximum O2 uptake (VO2max) and arterial blood oxygenation was determined in rats acclimated to simulated altitude (370-380 Torr barometric pressure) for 3 wk (HxBic) and in normoxic littermates (NxBic).
