[Giant lipoma of the thigh: report of a case].

The clinical findings and surgical management of a 58 years old woman with a large lipoma of the thigh are reported. Giant lipomas of the thigh, infrequently observed, are of interest because causing functional limitation and lymphedema, due to their tendency to recur after surgical removal and their potential hazard of malignant transformation. Specific diagnostic tools are discussed. Surgical excision is the first-choice treatment of a giant lipoma of the thigh.

[Functional results of experimental autologous transplantation of the pancreas].

The autotransplant of the left lobe of the pancreas in the latero-cervical region has been successfully performed in 38 adult beagles with a mean cold ischemia time of 52 minutes. Juice volume and amylase, protein and bicarbonate outputs were resumed postoperatively as soon as 6 hours. A single case of thrombosis of the mesenteric vein occurred; all other pancreatic grafts showed good histological vitality at 30 days. This procedure of autografting is proposed as a valid experimental model for the pathophysiologic study of acute pancreatitis.

[Inequalities in mortality in the Italian longitudinal studies].

The article presents some of the most relevant results on inequalities in mortality, obtained by the two Italian longitudinal studies carried out in Turin, and Tuscany (in Leghorn and Florence). The two studies share the same methodology. Each database contains census data, information from population register and from death certificates. The authors approach this issue not in an analytical way (as they did in the works cited in the reference list), but answering some questions, relevant both from a scientific and a political point of view. How big are the health inequalities in Italy? Are the health inequalities in Italy increasing or decreasing? Are the health inequalities due to absolute or to relative deprivation? Does the mortality profile of the Italian population express the presence of old or new health inequalities? Can the health inequalities be reduced? The study's results prove that the health inequalities in Italy are deep and strictly related to individuals' position in the social fabric. Facing the other questions the authors focus only in the Turin data. From the 1970's to the 1990's the health inequalities in Turin have increased, despite of general improvement of population's health condition and the progressive reduction of the size of deprived groups. Turin data support both the hypotheses on the source of health inequalities, using long term unemployment as absolute deprivation's indicator, and status' inconsistency as (a row) indicator of relative deprivation. The growth of drug-related causes of death (AIDS and overdose) shows that in the Turin and--quite reasonably--Italian population old and new health inequalities live together. The essay closes offering evidence on the possibility to reduce health inequalities. For this purpose the authors analyses the Turin trend of avoidable deaths and infant and adolescent mortality.

[Deprivation and mortality: a deprivation index suitable for geographical analysis of inequalities].

UNLABELLED: FOREGROUND: A national deprivation index suitable for geographical analysis of inequalities in health is not yet available in Italy, although the link between deprivation and health has been clearly demonstrated in our country in a number of studies. OBJECTIVES: 1) To describe a deprivation index in Italy at municipal level, based on the percentage of selected census variables (simple components) 2) To analyse general mortality according to deprivation categories at municipal level in Italy 3) To measure the size of ecological bias using the Turin Longitudinal Study. SETTING: Italy (1-2), Turin (3). MATERIALS: 1) 1991 census data base at municipal level 2) General mortality in Italy by municipality and age bands in 1990-92. 3) Turin Longitudinal study 1991-1995. METHODS: 1) Percentages of selected indicators of inequalities for all the 8.100 Italian municipalities present at 1991 census were calculated. Factorial analysis were performed in order to help in selecting the most valuable ones. The final choice led to five indicators (low education, unemployment, rented occupier housing, no indoor bathroom, lone parent with childhood). A simple additive index was computed using the method of the sum of normal standard deviates of each component 2) Correlation of indexes with mortality was performed; SMR for each deprivation category were computed; 3) Computation of the index at different levels: individual (one million individuals), census ward (3657 wards), statistic zone (92 statistic zones), two neighborough levels (23 and 10 neighboroughs) was conducted; differential analysis was performed for each level and index category, allowing for comparison among results, adjusting for age. MAIN RESULTS: Increasing deprivation was significantly associated with mortality from all causes: there was up to a 20 percent increase in mortality between the highest and lowest quintile. The relationship was linear with no apparent threshold. The slope of the relationship between deprivation and mortality varied among regions. Differentials in inequalities measured by individual and census tract level resulted to be very small; ecological bias arises when larger areas are taken into account. CONCLUSIONS: An area based measure of deprivation has proved a valuable tool in examining differentials in death and is likely to prove of continuing value to health authorities in planning the delivery of health care.

[Social differences and indicators of perceived health, chronic diseases, disability and life style in the 1994. ISTAT national health interview survey].

In this paper social differences in health, analysed by different dimensions (perceived health, chronic diseases, functional deficits and disability) and social differences in lifestyle, in particular smoking habit and use of health services for the prevention of some female tumours, are described. The study is based on the data collected in the National Interview Survey on Health Status and Use of Health Care Services, conducted by ISTAT in the 1994. The analysis has been performed separately for males and females, computing Prevalence Rate Ratios (PRR) standardized by age. Educational level and social class, based on Schizzerotto's classification, have been used as determinants of differences in health and lifestyle. Unfavourable perception of health status and most of chronic diseases, referred as diagnosed by a doctor, show an increasing prevalence with decreasing educational level. Less striking differences are observed in the occurrence of injuries and in the restriction of daily life activities caused by diseases. A lower educational level corresponds to a regular increase in the proportion of disabled subjects. Females show higher differences than males in overweight and underweight prevalences in favour of more educated. Smoking habit shows an inverse correlation with education in males and a direct correlation in females, while attempts to quit smoking are more common among more educated individuals. Among women, the tendency to use screening tests for the prevention of some tumours is directly proportional to the educational level. Similar findings were obtained using the social class, with small bourgeoisie and working class showing similar excess risks, compared to bourgeoisie. This study found significant social inequalities in health status and in lifestyle in Italian population in 1994. The discussion argues that in absence of preventive interventions on disadvantaged groups of the population an increase of social differences in health is predictable.

[Cholelithiasis in men. Observations on a case series of surgically treated 3,047 patients].

Age and clinical presentation as acute cholecystitis have widely been found to be predictors of outcome after cholecystectomy. Recently, male gender has been cited in several studies as a possible prognostic factor. A single Institution cholecystectomy registry (3.047 cases between 1959-1997) comprising 966 (31.7%) men and 2.81 (68.3%) women was retrospectively analysed. Men experienced significantly higher rate of major complications (5.3% vs 3.2%; p < 0.01) and mortality (1.55% vs 0.62%; p < 0.03). By logistic regression analysis, it was found that male gender, acute cholecystitis, respiratory and cardiovascular system disease were significantly related to postoperative morbidity. Age older than 65 years, male gender, respiratory and cardiovascular diseases were factors negatively affecting operative mortality.

[Shift work and health].

Shiftwork, in particular night work, causes disruption of biological rhythms, perturbation of social and family life, with a negative influence on performance efficiency, health and social well-being. Deterioration of health can manifest in the short-term as sleep disorders, jet-lag syndrome and accidents; in the long term there is an increased risk of gastrointestinal, psychoneurotic and cardiovascular diseases, and impairment of the female reproductive function. The evaluation of a worker's fitness for shift and night work should be strictly connected with a careful job analysis, as the primary requisite is to arrange shift schedules according to ergonomic principles and to assure suitable compensative measures. Occupational health physicians should advise shiftworkers about proper coping strategies and carefully evaluate health disorders with absolute or relative contraindications. Health checks should be aimed at detecting early signs of intolerance and their frequency should be set in relation to specific working conditions, individual characteristics, and social factors known to influence tolerance to shift work.

[Air pollution and daily mortality in Turin, 1991-1996].

A time series study was carried out to assess the relationship between the air pollutants measured by the air quality monitoring network and daily mortality in Turin, Italy. We used TSP, SO2, NO2, O3, and CO concentrations measured from 1-1-1991 to 31-12-1996 at three stations of the city network, chosen to represent different, typical circumstances of exposure to air pollution in the town. The analysis was performed by robust Poisson regression model including loss smoothing functions to allow for long-time trend, seasons, temperature and relative humidity. Dummy variables for the days of the week and holidays were also included. The relative risk of death for a unit increase in the pollutant concentration either during the same day (lag 0) in the previous ones (lag up to 5) was computed. The unit increase was 50 micrograms/m3 for TSP, SO2, NO2, O3, and 2 mg/m3 for CO. The average daily number of deaths for natural causes was 21. The relative risks for total mortality were 1.04 for TSP (lag 1), 1.10 for SO2 (lag 2), 1.06 for NO2 (lag 1), 1.01 for O3 (lag 0), 1.03 for CO (lag 1). The relative risks were 1.05 for TSP (lag 0), 1.12 for SO2 (lag 2), 1.07 for NO2 (lag 1), 1.03 for O3 (lag 0), 1.03 for CO (lag 1) for cardiovascular mortality, and 1.08 for TSP (lag 2), 1.20 for SO2 (lag 2), 1.12 for NO2 (lag 2), 1.03 for O3 (lag 2), 1.05 for CO (lag 2) for respiratory mortality.

[Social differences in cancer incidence, fatality, and mortality in Turin].

INTRODUCTION: The study of social differences in health is today focused on determinants. The knowledge of determinants is useful for the definition of policies to tackle inequities. The aim of this paper is to analyse the social distribution of cancer incidence, fatality and mortality in the city of Turin during the 80's and to estimate the amount of inequality produced within the health system. SOURCES OF DATA: The social distribution of the risk of death in Turin during 1981-1989, estimated from the Turin Longitudinal Study, is compared with incidence and fatality during approximately the same time period. RESULTS: Among men, the relative risks for all cancer sites, among social classes, appear to confirm the hypothesis of a multiplicative model of incidence and fatality. In particular, colo-rectal, prostatic, bladder cancers and lymphoma and leukaemia show relative risks similar to the expected ones. Cancers of larynx, lung and stomach seem to be less coherent. Among women, colon-rectum, lung, breast and lymphoma and leukaemia show coherent results, whereas relative risks for uterus are far from the expected. DISCUSSION: The coherence with the expected values of the social distribution of mortality suggests the adequacy of the multiplicative model for the provision of mortality from incidence and fatality. Therefore it is possible to state that the portion of inequality in health originated within the health system is big enough to suggest the need to put the equity in the access to health services in the agenda of interventions.

[Aging of the working population in the European Union].

The working population over 50 years of age will grow considerably during the next 15 years. After 2010, the number of retired people over 65 years of age will be almost double that of 1995, with a strong impact also on working conditions and the labour market. Work ability is a dynamic process that changes, through its components, throughout life and is the result of the interaction between individual resources (including health, functional capacity, education and skills), working conditions, and the surrounding society. Work ability creates the basis for the employability of an individual, which can be supported by a number of actions (e.g. legislation on work and retirement) and social attitudes (e.g. age discrimination). Consequently, the prevalence of limitations in work ability varies significantly according to how it is evaluated and the frequency of work disability can vary considerably in different times, locations and populations. The Work Ability Index, created and used in a Finnish 11-year longitudinal study, has been proved a useful practical tool for the assessment of workers' fitness and a good predictor of work disability. Measures able to restore, maintain or promote work ability depend on the current work status and the needs of the target groups, and must concentrate on work content, physical work environment and the work community. The actions targeted towards the individual, on the other hand, concentrate on strengthening the health status and functional resources of the workers and developing professional expertise and skills. Correctly targeted and integrated measures improve work ability of ageing workers and therefore lead to improved work quality, increased productivity and also improved quality of life and well-being. They also have positive long-term effects on the "third age", when the worker retires.

[Work capacity and aging].

Maintaining a good work ability depends on satisfactory health and employment status, which is supported by suitable working conditions and correct life styles. From the biological perspective, ageing means a foreseeable progressive and overall deterioration of the various physiological systems, but not of such a kind and severity to consider most people over 50 as too old or unfit for work, as has been shown by several studies that assessed work ability not only in terms of biological age, but of functional age and actual work output. From the physio-pathological perspective, we can observe either illnesses associated with the passage of time or age-related changes that might precipitate diseases, as well as environmental changes that modulate ageing and developmental changes that accelerate or retard ageing. From the practical point of view, it should taken into account that job demands often do not follow the natural biological and functional changes of the individual, consequently the relative work load can be higher in older workers. On the other hand, ageing also means a professional growth in terms of strategic ability, shrewdness, wisdom and experience. The high interindividual variability of physical, mental and social conditions that is observed with the increase in age makes it necessary to adopt flexible and personally tailored measures, as shown by recent surveys in some European countries aimed at reducing age discrimination and work disability, and at promoting work ability by means of actions directed towards both improvement of work organisation and support of psycho-physical conditions of older workers.

[Layered and mass sutures in the closure of median laparotomies].

A retrospective comparison of 2830 patients with midline abdominal incision closures was made. Dehiscences, infections, hernias were compared examining continuous mass closures (group A) versus interrupted mass closures (group B) and interrupted layered sutures (group C). The three groups were well matched for known risk factors for each of the above complications. Mass closures produced a significant higher number of infections (p = 0.0006) and hernias (p = 0.0001). There was no significant difference in the rate of dehiscences in the three suture groups (p = 0.07). A significant correlation was found in all three groups between the incidence of infections and that of outcoming incisional hernias. In the current study layered closure of the of the midline abdominal wounds yielded better results when compared with both running mass and interrupted mass closures. The knowledge of these findings might help when choosing the procedure to close a midline abdominal incision.

[Ambulatory closed surgery for the treatment of pilonidal sinus].

Pilonidal disease (PD) is a common chronic disorder of the sacrococcygeal region afflecting young people. Despite several methods for treating PD have been described, the management remains controversial. Recent reports have advocated different surgical approaches such as open or closed technique, but recurrence plagues all forms of therapy. We conducted this case review to evaluate the validity of an outpatient closed technique in the treatment of chronic pilonidal disease. Between January 1997 and July 1999, 65 consecutive patients with quiescent chronic PD were electively treated by surgical excision of the cyst and primary closure. There were 47 men (72%) and 18 women (28%) in this study. Patients ranged in age from 14 to 47 years, the average age being 21 years. The median healing time was 8 days and the median time to return to full work was 20 days (range 10-25). Infection and recurrence rates were 1.5% and 4.6% respectively. There was no correlation among recurrence rate, postoperative infection, or prior surgery. Cyst excision and primary closure is a safe, low cost operation with a very high long-term success rate and a negligible rate of complications. It can successfully be performed under local anaesthesia in an outpatient facility.

[Carcinoma of the male breast. Prognostic factors and outcome of surgical treatment].

A retrospective study was made on 18 male patients with breast carcinoma treated at the Department of Surgery "Pietro Valdoni" of the University "La Sapienza" of Rome, Medical School. Demographics, pathology, stages, and treatment were determined from clinical reports. All patients but one underwent modified radical mastectomy. The length of follow up averaged 57.5 months. Five years actuarial survival rate was 62%. In the current study the Authors suggest that the clinical, prognostic and treatment features of breast carcinoma in men are similar to those reported in literature for post-menopausal women.
