[Chondrosarcoma of the hand arising from multiple enchondromas: a case report]. / Chondrosarkom an der Hand bei multiplen Enchondromen: ein Fallbericht.

Malignancy occurs more often in multiple enchondromas than in solitary enchondromas. In the hands the rate is about 14%. We amputated the third ray of the hand in a young man with recurrence of an enchondroma. The histology showed a low grade chondrosarcoma. The patient had no tumour recurrence or metastasis in the following 5 years. We describe the evaluation as well as the treatment and outline the literature.

Consumption of whole grain food and its determinants in a general Italian population: Results from the INHES study.

BACKGROUND AND AIMS: Whole grain (WG) food consumption is associated with lower risk of cardiovascular disease, cancer and neurological diseases. The aim of this study was to assess the consumption of WG food and its major demographic, socioeconomic, psychosocial and behavioral determinants in a general Italian population. METHODS AND RESULTS: Data were from the Italian Nutrition & Health Survey (INHES), a telephone-based survey established in 2010-2013 including 9422 participants aged ≥5 years from all over Italy. WG food intake was assessed by the European Food Propensity Questionnaire and included bread, pasta, breakfast cereals, biscuits and WG soups. WG consumption was categorized as none, occasional (<1 time/week) and regular (≥1 time/week). Overall, 26.9% of the sample reported a regular consumption of WG food (27.2% of adults aged 20-97 y, and 21.9% of children/adolescents aged 5-19 y). In both age-groups, the major food source contributing to total WG intake was WG bread followed by WG pasta. Among adults, greater consumption of WG was associated with healthier lifestyle (e.g. sport activity), and higher educational level. Eating meals outside of the house in adults, and spending >2 h/day watching TV in children/adolescents were inversely associated with WG intake. CONCLUSIONS: The percentage of WG consumers in Italy in 2010-2013 appears to be quite low and still below that recorded in other countries of Europe where consumption is frequently over 50 percent. WG consumption is likely to be influenced by socioeconomic status and is associated with a number of psychosocial factors, meal patterns and eating-related behaviors.

Impact of combined healthy lifestyle factors on survival in an adult general population and in high-risk groups: prospective results from the Moli-sani Study.

BACKGROUND: There is poor knowledge on the association between combined lifestyles with mortality risk among individuals at high risk, and little is known on the biological mechanisms that could be on the pathway. METHODS: Longitudinal analysis on 22 839 individuals from the Moli-sani Study (Italy, 2005-2010). Among them, we identified 5200 elderly individuals (≥65 year), 2127 subjects with diabetes and 1180 with cardiovascular disease (CVD) at baseline. A healthy lifestyle score (HLS) was calculated, allocating 1 point for each of the following: abstention from smoking; adherence to Mediterranean diet; physical activity; absence of abdominal obesity. Hazard ratios (HR) with 95% confidence intervals (95%CI) were calculated by multivariable Cox regression and competing risk models. RESULTS: During 8.2 years of follow-up, 1237 deaths occurred. In the general population, adherence to all four healthy lifestyles, compared with none or 1, was associated with lower risk of all-cause (HR = 0.53; 95%CI:0.39-0.72), CVD (HR = 0.54; 0.32-0.91), cancer (HR = 0.62; 0.39-1.00) and mortality from other causes (HR = 0.39; 0.19-0.81). A 1-point increase in HLS was associated with 20%, 22% and 24% lower risk of total mortality among the elderly, in subjects with diabetes or CVD, respectively. Traditional (e.g. blood lipids), inflammatory (e.g. C-reactive protein) and novel biomarkers (e.g. markers of cardiac damage) accounted for up to 24% of the association of HLS with all-cause mortality risk in the general population. CONCLUSIONS: The impact of combined four healthy lifestyles on survival was considerable, both in the general population and among high-risk subgroups. Inflammatory and novel biomarkers of CVD risk explained a substantial proportion of this association.

Learning by counting blood platelets in population studies: survey and perspective a long way after Bizzozero.

Platelet count represents a useful tool in clinical practice to discriminate individuals at higher risk of bleeding. Less obvious is the role of platelet count variability within the normal range of distribution in shaping the individual's disease risk profile. Epidemiological studies have shown that platelet count in the adult general population is associated with a number of health outcomes related to hemostasis and thrombosis. However, recent studies are suggesting a possible role of this platelet index also as an independent risk factor. In this review of adult population studies, we will first focus on known genetic and non-genetic determinants of platelet number variability. Next, we will evaluate platelet count as a marker and/or a predictor of disease risk and its interaction with other risk factors. We will then discuss the role of platelet count variability within the normal distribution range as a contribution to disease and mortality risk. The possibility of considering platelet count as a simple, inexpensive indicator of increased risk of disease and death in general populations could open new opportunities to investigate novel platelet pathophysiological roles as well as therapeutic opportunities. Future studies should also consider platelet count, not only platelet function, as a modulator of disease and mortality risk.

Mediterranean-type diet is associated with higher psychological resilience in a general adult population: findings from the Moli-sani study.

BACKGROUND/OBJECTIVE: Psychological resilience is a measure of stress coping ability and has been associated with favourable health outcomes. While evidence on the relationship of dietary habits with a number of psychosocial conditions is available, there is lack of studies on their association with psychological resilience in a general adult population. SUBJECTS/METHODS: Cross-sectional analysis on 10 812 subjects recruited within the cohort of the Moli-sani study (2005-2010). Psychological resilience was measured by the 25-item Connor-Davidson Psychological Resilience Scale. Food intake was recorded by the EPIC food frequency questionnaire and adherence to Mediterranean diet was appraised by both a Greek Mediterranean diet score and an Italian Mediterranean Index. Empirically derived dietary patterns were obtained by principal factor analysis. Multivariable linear regression analysis (95%CI) was used to test the association between dietary scores and psychological resilience. RESULTS: Higher adherence to Mediterranean-type diets or consumption of a vegetable-based dietary pattern (obtained from principal factor analysis) were positively associated with psychological resilience (ß=0.43; 95%CI: 0.19-0.66, ß=0.92; 0.69-1.16, and ß=1.18; 0.93-1.44, for Greek Mediterranean diet score, Italian Mediterranean Index and the 'Olive oil and vegetables pattern', respectively). Dietary polyphenol or antioxidant intakes and greater variety in fruit and vegetable consumption were also positively associated with psychological resilience, while the associations with Western-like diets were weak. CONCLUSIONS: In conclusion, Mediterranean diet, vegetable-based dietary patterns and better diet quality were all positively associated with higher psychological resilience, whereas Western-type diets were not.

Association of pasta consumption with body mass index and waist-to-hip ratio: results from Moli-sani and INHES studies.

BACKGROUND/OBJECTIVES: Pasta as a traditional component of Mediterranean diet (MeD) in Italy has not been studied in detail in the management of body weight. This study aimed at evaluating the association of pasta intake with body mass index (BMI) and waist-to-hip ratio, in two large epidemiological datasets. SUBJECTS/METHODS: A total of 14 402 participants aged ⩾35 years randomly recruited from the general population of the Molise region (Moli-sani cohort) and 8964 participants aged >18 years from all over Italy (Italian Nutrition & HEalth Survey, INHES) were separately analyzed. The European Prospective Investigation into Cancer and Nutrition (EPIC)-food frequency questionnaire and one 24-h dietary recall were used for dietary assessment. Weight, height, waist and hip circumference were measured in Moli-sani or self-reported in INHES. Residuals methodology corrected for either total energy intake or body weight was used for the analysis of pasta intake. RESULTS: Higher pasta intake was associated with better adhesion to MeD in both genders (P for both<0.001). In the Moli-sani study, after multivariable analysis, pasta-energy residuals were negatively associated with BMI in women but not in men (ß-coef=-0.007, P=0.003 for women and ß-coef=-0.001, P=0.58 for men). When pasta intake-body weight residuals were used, pasta intake was significantly and negatively associated with BMI in crude and multi-adjusted models (including adhesion to MeD) in both genders and Moli-sani and INHES studies (for all ß-coef<0, P<0.05). In the Moli-sani study, pasta-body weight residuals were significantly and negatively associated with waist and hip circumference and waist-to-hip ratio (for all ß-coef<0, P<0.05). CONCLUSIONS: As a traditional component of MeD, pasta consumption was negatively associated with BMI, waist circumference and waist-to-hip ratio and with a lower prevalence of overweight and obesity.

Flavonoid and lignan intake in a Mediterranean population: proposal for a holistic approach in polyphenol dietary analysis, the Moli-sani Study.

BACKGROUND/OBJECTIVES: The objective of this study is to extract and assess data on the dietary intake of flavonoids and lignans in a healthy free-living Mediterranean population, using newly updated harmonized European Union food composition data. This work also aimed at analyzing in a holistic way the total content of the diet in major classes of polyphenols. SUBJECTS/METHODS: Six thousand nine hundred and eighty-one men and 7048 women (aged ⩾ 35 years) of the Moli-sani cohort, randomly recruited from the general population, were analyzed. The European Prospective Investigation into Cancer (EPIC) and Nutrition-Food Frequency Questionnaire was used for dietary assessment. The polyphenol content of each food group was evaluated using Eurofir BioActive Substances in Food Information System and the United States Department of Agriculture food composition tables (FCTs), when data were missing. Flavonol, flavone, flavanone, flavanol, anthocyanin, isoflavone and lignan intakes were calculated and polyphenol antioxidant content (PAC) score (-28, 28) constructed, to assess the total content of the diet in these nutrients. RESULTS: Seasonal and citrus fruits, leafy, grain, pod and root vegetables, and onions and garlic accounted for different proportions (11-70%) of the total intake of different polyphenols. Within the Moli-sani population, men or older, or no/former smokers, or physically active or obese/overweight individuals presented higher consumption of flavonoids, lignans and PAC score (P for all <0.01). Multiple regression analysis showed that PAC score and its seven components were positively associated with Mediterranean diet (MeD) adherence in both genders (ß-coefficient >0, P<0.001). In addition, 1 unit increase in PAC score was associated with 7.1-7.8% increase in the likelihood of high MeD adherence (P<0.001). CONCLUSIONS: The intake of flavonoids and lignans in an European Union population was calculated using harmonized European Union FCT data. In addition, a holistic approach in dietary analysis of polyphenol intake was proposed.

[Factitious disorder and self-mutilation in hand and plastic surgery]. / Artifizielle Störungen und selbstverletzendes Verhalten in der Hand- und Plastischen Chirurgie.

Self-mutilation in the context of factitious disorder can lead to prolonged and complicated treatment in every medical field. Because of a prevalence of 1-5% in hospitalised patients, it is important to be aware of this disorder to protect patients from self- and foreign-induced harm. Often the patient history gives important hints. The different manifestations of this disorder, the specific doctor-patient relationship, several techniques of confrontation and current treatment are presented. Clinical cases from the fields of hand and plastic surgery are presented.

[Intramedullary Kirschner wire osteosynthesis in treatment of distal metacarpal fractures]. / Die intramedulläre Kirschner-Drahtosteosynthese zur Behandlung distaler Metakarpalfrakturen.

The intramedullary Kirschner wire fixation of distal metacarpal fractures reported by Foucher et al. combines the known advantages of intramedullary implants with a reduction of iatrogenic soft tissue trauma. We applied this minimal invasive internal fixation technique in 38 patients with fractures dislocated by more than 20 degrees and/or with rotatory deformity. After opening the intramedullary cavity from the base of the respective metacarpal bone and after fracture reduction, two pre-bent Kirschner wires were intramedullary inserted in an orthograde fashion. The pre-bent distal end of the wire in the form of a hockey club allows an additional closed reduction of the displaced distal fracture fragment. Intraoperative complications did not occur. A fixation in a plaster splint followed for one week only. The elastic fixation of the wires working as springs is stable enough to allow physiotherapeutic exercises. After the third postoperative week, the intensity of physical exercise was increased. 36 of the 38 patients were followed. With one exception, all fractures were healed in a proper position. The wires were removed under local anaesthesia on an outpatient basis after six to eight weeks and full mobility of the fingers was achieved in 34 patients at that time. Complications included one redislocation and one distal wire perforation.

Release of anti-inflammatory mediators after mechanical trauma correlates with severity of injury and clinical outcome.

Excessive synthesis of proinflammatory cytokines [tumor necrosis factor (TNF)-alpha and interleukin (IL)-1 beta] after trauma has been correlated with poor outcome. Recently, naturally occurring inhibitors of TNF-alpha and IL-1 beta have been characterized such as soluble TNF receptors (sTNFRs) and IL-1 receptor antagonist (IL-1ra). The present study was undertaken to determine whether injury results in a rise of circulating sTNFRs and IL-1ra. If so, whether plasma levels of these anti-inflammatory mediators correlate with severity of injury and clinical outcome of these patients. Injured patients (n = 213) showed significantly increased sTNFR and IL-1ra plasma levels throughout the observation period of 14 days, compared with healthy volunteers (n = 127). Patients with severe injury (Injury Severity Score > 16 points) revealed higher levels (p < 0.05) of sTNFRs and IL-1ra than patients with minor trauma (Injury Severity Score < or = 16 points). Patients who died from injury demonstrated increased (p < 0.05) sTNFR p55 and IL-1ra plasma levels, compared with survivors. Thus, anti-inflammatory mechanisms are activated after trauma dependent on severity of injury. Because increased plasma levels of anti-inflammatory reacting proteins portended poorly for patient survival, these mediators may contribute to prediction of outcome after severe injury.

[Increased plasma level of Type I (p55) and Type II (p75) TNF-receptors following trauma]. / Erhöhte Plasmaspiegel der löslichen TNF-Rezeptoren (sTNFRs) Typ I (p55) und Typ II (p75) nach Trauma.

Excessive synthesis and release of proinflammatory cytokines following trauma have been correlated with poor outcome of injured patients. TNF-alpha seems to play a pivotal role as trigger for the induction of systemic inflammation. Recently, two naturally occurring inhibitors of TNF-alpha, soluble TNF-receptors (sTNFRs) p55 and p75, have been characterized. The present study was undertaken to determine whether severe trauma increases circulating sTNFRs dependent on severity of injury. Injured patients (n = 190) revealed significantly increased plasma levels of both sTNFRs throughout the observation period of 21 days compared to healthy volunteers (n = 125). Patients with severe injury (ISS > 16 pts; n = 130) revealed higher (p < 0.0001) levels of sTNFRs on day of admission than patients with minor trauma (< or = 16 pts; n = 60). Thus, anti-inflammatory mechanisms are activated during the posttraumatic course dependent on severity of injury.

Increased release of soluble tumor necrosis factor receptors into blood during clinical sepsis.

OBJECTIVES: To examine the kinetics of altered soluble tumor necrosis factor receptors (sTNFRs) released in patients with severe sepsis, their correlation with the morbidity and mortality of these patients, and the role of endotoxin to induce cleavage of sTNFRs. DESIGN: Soluble TNFR levels in plasma obtained from 40 patients with severe sepsis (mean [+/- SD] Acute Physiology and Chronic Health Evaluation [APACHE] II score, 27.9 +/- 7.0 points) on days 0, 1, 3, 5, and 10 after sepsis diagnosis were measured using specific enzyme-linked immunological binding assays and compared with levels in 75 control patients without infection. In addition, an ex vivo model consisting of lipopolysaccharide stimulation of human whole blood as a relevant physiological milieu was used. Blood from patients with sepsis and control patients was incubated in the presence or absence of lipopolysaccharide (1 mg/L) for 0, 1, 2, 4, 8, and 24 hours. Plasma levels of sTNFRs from both groups were determined using the enzyme-linked immunological binding assays. RESULTS: In patients with sepsis, plasma levels of both sTNFRs were markedly (P < .01) increased during the whole observation period, compared with those of control patients, and correlated (P < .001) with the simultaneously obtained APACHE II and multiple organ failure scores, as well as with mortality. Although incubation of whole blood with lipopolysaccharide increased the release of sTNFR p55 and p75 in both groups, sTNFR concentrations in blood from control patients remained low compared with those of patients with severe sepsis, despite stimulation of whole blood with a maximum lipopolysaccharide concentration. CONCLUSIONS: These data indicate that an enhanced release of sTNFRs during severe sepsis is not solely induced by endotoxin. Since the degree of increased sTNFR levels portended poorly for patient survival, elevated sTNFR levels may represent a good marker for severity of sepsis, thus predicting outcome.

[The medical record at the center of medical informatics]. / Die Krankengeschichte im Zentrum der medizinischen Informatik.

Several areas in medical institutions, particularly the technical and administrative ones have been governed by computers for a long time. The proper medical work field (diagnosis, treatment, follow-up, correspondence and billing) however has hitherto mostly been ignored by data processing. We describe an electronic medical record introduced 4 years ago. All aspects of medical practise and all the specialists involved in patient care are integrated in the electronic document. In the center is a medical base of knowledge adaptable to all specialties as well as an expert system for direct control of the data entered by all concerned persons.
