Hyperfibrinogenemia and metabolic syndrome in type 2 diabetes: a population-based study.
BACKGROUND: It has been hypothesized that fibrinogen clusters with several components of the metabolic syndrome, thus increasing its cardiovascular risk. The aims of the present study were to assess in a large population-based cohort of patients with type 2 diabetes (1) variables associated with fibrinogen and (2) the relationship between hyperfibrinogenemia, a number of components of the metabolic syndrome, and coronary heart disease (CHD). METHODS: We identified a cross-sectional, population-based cohort of 1574 patients with type 2 diabetes using multiple sources of ascertainment. Components of the metabolic syndrome were hypertension (systolic blood pressure > or = 160 mmHg and/or diastolic blood pressure > or = 95 mmHg and/or treatment with antihypertensive drugs), dyslipidemia (tryglicerides >2.82 mmol/l and/or HDL-cholesterol <1.03 mmol/l), hyperuricemia (uric acid >416 micromol/l) and increased albumin excretion rate (AER > or = 20 microg/min). RESULTS: Fibrinogen increases with age, HbA(1c), smoking, hypertension and a number of components of the metabolic syndrome, even after adjustment for confounders. Prevalence of CHD increases linearly across quartiles of fibrinogen (from 26.1 to 40.6%, p=0.046). However, in logistic regression, after adjustment for both confounders and known risk factors for CHD, the role of fibrinogen is no more significant, whereas ORs for HbA(1c) between 6.8 and 8.8% and >8.8% vs values <6.8% are, respectively, 1.91 (95% CI 1.36-2.69) and 1.56 (1.07-2.27). CONCLUSIONS: This population-based study shows that fibrinogen increases with age, HbA(1c), smoking, hypertension and a number of components of the metabolic syndrome, independent of major confounders. We also found that poor blood glucose control was associated with CHD.

Lipoplastics of legs: our experience with a new cannula compared with classical technique.
The Authors compare the results obtained between two groups of patients suffering from leg lipodystrophy, who were subjected to a reducing lipoplasty. In the first group, surgeons made use of a new sort of cannula, deprived of the classical grip, whereas in the second group, they employed the traditional probe. The best results, achieved with the first group, prove this new operating system is really effective, particularly on legs, for the following reasons: (1) Higher precision and better control of the instrument (2) Swan-neck cannula abolition (3) Opportunity to operate with both hands (4) Halved operating time (5) No tiredness after the operation.

Liposculpture with ultrasound: biomedical considerations.
The authors, after a careful review of the scientific literature and on the basis of biophysical concepts with their own experience, conclude that high-intensity ultrasounds (US) are responsible for some biological lesions, which are partly unknown. US can cause burns and skin necrosis; thus, our employment of this technique must be correct, justified, and practiced very carefully and shrewdly and its advantages versus traditional liposuction must be reviewed.

Localized pigmented villonodular synovitis of the knee.
Pigmented villonodular synovitis (PVNS) is a well-recognized lesion that may affect any joint but is frequently found in the knee. It is a rare condition, especially in the localized form, and is still cause for discussion regarding to its pathogenesis and treatment. We report four cases of localized PVNS each one presenting with different clinical signs and symptoms. In one of our cases, a pedunculated mass and villous-like projections of the surrounding synovium were associated. Each case was studied with magnetic resonance imaging, treated arthroscopically, and the diagnosis confirmed by histological examination. Arthroscopy is an effective tool for both diagnosis and treatment.

Liver pathology in cytomegalovirus infection associated with hepatitis B virus.
A retrospective study was carried out in 56 patients to establish the association of cytomegalovirus (CMV) with active or inactive hepatitis B virus (HBV) infection as a possible risk factor in the development of severe liver disease. Patients with positive CMV serology and active or inactive HBV infection had elevated alanine aminotransferase activity and had a relatively high incidence of more severe lesions (chronic hepatitis and active cirrhosis). In the absence of CMV, only one case of cirrhosis was identified compared with seven cases of hepatic fibrosis. By analogy with hepatitis C virus, CMV may bring about activation of the host inflammatory response against hepatocytes following HBV infection, resulting in the development of severe hepatitic disease.

Elevated alanine aminotransferase in blood donors: role of different factors and multiple viral infections.
Many different aetiological agents stimulate alanine aminotransferase (ALT) production. Viral markers and other aetiologies were investigated in 2166 individuals, randomly selected from 10,000 consecutive blood donors. Elevation of ALT was found in 10.8% of subjects. Grouping donors according to ALT level and correlating with, respectively, hepatitis B core antibody (HBcAb), cytomegalovirus antibody alone, or associated with HBcAb, showed similar findings (high ALT 11.1%, normal 11.6%; high 85.4%, normal 81.4%; high 10.2%, normal 11.0%, respectively). Hepatitis C virus (HCV) antibody was found to be significantly associated with elevated ALT levels (high 1.7%, normal 0.26%). Other causes of ALT elevation were alcohol abuse (17%), obesity (25%) and dyslipidaemia (38%), but in 11% there was no obvious aetiology. Although HCV is a rare cause of elevated ALT in blood donors, it seems to be the only virus, among those tested, to account for liver damage. This may be due to the non-protective role of HCV antibody, the low specificity of ALT, or the pathogenic role of uninvestigated viruses.

The role of substance P in cerebral ischemia.
Tackykinins are involved in the inflammatory process of a large number of diseases. The role of the tachykinins in ischemic brain injury was evaluated by the serum levels of Substance P (SP), one of the most known tachykinins and detected by a competitive enzyme immunoassay. The study was performed in 15 human females and 3 human males with typical manifestation of complete stroke (12 cases) or transient ischemic attack (6 cases). The mean SP level in the serum of patients with transient ischemic attack (0.53+/-0.25 ng/ml) and of patients with complete stroke (0.31+/-0.14 ng/ml), showed significantly higher values than in controls (0.10+/-0.02 ng/ml). Moreover, in transient ischemic attack, the SP values were significantly higher than in cerebral complete stroke. But SP levels, based on the timings of classification of patients (i.e. before 12 hours: 0.34+/-0.15 ng/ml vs. 12 to 24 hours: 0.26+/-0.11 ng/ml) with brain injury, did not show any significant difference. Both values anyway were significantly higher than in controls. Our original results demonstrate the SP increase during cerebral ischemia. Further studies are necessary to verify if SP has an effective physiopathological role in the neurological ischemic damage, or if it is only a concomitant phenomenon. Our data, if confirmed, will be particularly important, not only to improve the knowledge of cerebral ischemic injury, but also for diagnosis and therapeutic approaches.

Integrin beta2-chain (CD18) over-expression on CD4+ T cells and monocytes after ischemia/reperfusion in patients undergoing primary percutaneous revascularization.
beta2-integrin subunit (CD18) plays an essential role in leukocyte recruitment and adhesion in sites of endothelial injury. We analyzed the surface expression of CD18 on T lymphocytes and monocytes in a series of patients presenting acute coronary syndrome (ACS) who underwent primary percutaneous intervention (PCI) for coronary artery revascularization. We found that basal CD18 expression on peripheral blood-derived CD4+ (but not CD8+) T lymphocytes was significantly increased in ACS patients as compared with age-matched healthy volunteers. During primary PCI, a significant increase in CD18 molecule density was detected immediately after balloon deflation (reperfusion) on both CD4+ T cells and monocytes obtained from the right atrium (RT) as compared with basal values. These data suggest that upregulation of CD18 molecules plays an important role in local recruitment of CD4+ T cells and monocytes to the site of endothelial damage after ischemia/reperfusion, therefore being responsible, at least in part, for the inflammatory-mediated complications associated with primary PCI.

Prevention of atopic diseases in high risk babies (long-term follow-up).
Several studies have demonstrated that dietary and environmental manipulations in the first months of life have a protective effect on the development of allergic diseases in babies "at risk" of atopy. We have prospectively followed up 174 "high risk" infants who underwent dietary and environmental manipulations, such as exclusive breast-feeding for the first 6 months of life, supplemented if necessary with soy-protein formula (Isomil, Abbott), delayed weaning beyond the 6th month of life, and rigorous environmental manipulations for the elimination of house-dust mite and passive smoking. The low prevalence of atopic disease (10%) and the trivial course of the allergic manifestations in this "at risk" population confirm the effectiveness of this preventive program. Moreover, this study demonstrates that the incidence of atopic dermatitis peaks at 6 months, and decreases until it disappears. Food allergy appears only at 6 months and may disappear later. The incidence of asthma peaks at 6 and 36 months and decreases at low levels in the intervals. Allergic rhinitis develops not sooner than 36 months.

Hepatitis C virus: a high risk factor for a second primary malignancy besides hepatocellular carcinoma. Fact or fiction?
PURPOSE: Second primary malignancies occur more and more often. But the hepatocellular carcinoma (HCC) linked to a second primary cancer is not frequent. MATERIALS AND METHODS: A retrospective study focused on a second primary cancer was performed in 37 patients with HCC, aged between 46 and 81 years, 27 males and 10 females. RESULTS: 5 out of them (13.5%), 3 males and 2 females, developed a second primary neoplasm before or after HCC. In 3 cases the second malignancy was a carcinoma of the kidney, of the breast, and the prostate. The fourth patient had a Hodgkin's lymphoma before HCC. The last and most unlucky case, besides HCC, had a basal cell carcinoma, a colorectal cancer, and a bladder carcinoma. The common data of these 5 patients were the presence of anti-HCV antibodies and the positivity of the HCV RNA polymerase reaction. One patient was also HBV positive. CONCLUSION: Considering that a large number of virus has been found linked to human cancers, our results brought us to hypothesize that HCV could have played an important role not only in the development of HCC but of the second primary malignancy too. This is likely favoured by constitutional or acquired biological and molecular alterations. Tumor suppressor genes alterations have been reported to be frequently linked to cancers of kidney and breast, of colorectal and skin, of prostate, and lymphoemopoietic tissue. Now just these organs are involved in our patients in addition to the liver. Our results, if confirmed, are of a relevant interest, considering that world-wide HCC is constantly increasing for the spreading of the virus risk-factors.

Sensitivity of serum tumor markers CEA and CA 15-3 in breast cancer recurrences and correlation with different prognostic factors.
The aim of this study was to evaluate the correlation between serum tumor markers CEA and CA 15-3 in breast cancer (BC) patients with disease relapse and different prognostic parameters at first operation. Sixty-two women (median age 55 years, range 35-83 years) who had undergone curative surgery for pT1-2 pN0-1 M0 breast cancer developed local recurrences, distant metastases or contralateral BC during a median relapse time of 53 months (range 25-149 months). Sensitivity of CEA, CA 15-3, and CEA + CA 15-3 together was 40.3%, 41.9% and 59.7%, respectively. No correlation (p = NS) was found between tumor markers sensitivity and type of recurrence, surgical procedure, histologic subtypes and hormone receptors rate. CEA significantly (p < 0.01) correlated with the size of the tumor and axillary node status and CA 15-3 with the age of the patients. In conclusion, CEA and CA 15-3 should be considered complementary in detecting BC recurrences but their sensitivity is low and independent of the majority of the prognostic parameters that may be considered before relapse.

Serum tryptase in allergic rhinitis: effect of cetirizine and fluticasone propionate treatment.
PURPOSE: A specific reaction against several kinds of inhalant allergens characterizes allergic rhinitis. Mast cells play a crucial role in the allergic inflammation releasing histamine and other mediators. Tryptase is considered to be a specific marker of mast cell activation. This study was devoted to evaluate the serum tryptase in allergic rhinitis and to evaluate the effect of cetirizine and fluticasone propionate on mast cell activation. 13 subjects, suffering from perennial allergic rhinitis induced by Dermatophagoides pteronyssinus, were studied. MATERIALS AND METHODS: Tryptase serum levels were detected by the fluoroenzymeimmunoassay (Pharmacia & Upjohn AB, Uppsala, Sweden). Blood samples were taken four times: before starting the study, after two weeks of 10 mg cetirizine treatment once a day, after two weeks of wash-out, and again after 15 days of 100 micrograms intranasal fluticasone propionate therapy twice a day. RESULTS: In allergic rhinitis, the basal values of serum tryptase (M +/- SD: 6.1 +/- 2.4 micrograms/l) were significantly higher than in controls (M +/- SD: 3.0 +/- 1.2 micrograms/l). After the antihistamine treatment, tryptase values (M +/- SD: 4.4 +/- 1.8 micrograms/l) decreased significantly (p < 0.001). After the stop of antihistamine treatment, tryptase levels increased (M +/- SD: 5.5 +/- 2.6 micrograms/l, p < 0.001). After the topical corticosteroid treatment, tryptase values decreased again significantly (M +/- SD: 4.5 +/- 3.1 micrograms/l, p < 0.04). CONCLUSIONS: All these data seem to confirm the effective action of cetirizine and fluticasone propionate on tryptase serum levels. While the action of corticosteroid is well known, the action of cetirizine is still to define, considering the recent reports on anti-inflammatory effect of the second generation of H1 receptor antagonists. Further studies are necessary to understand if the pharmacological effect on tryptase is a specific one of cetirizine, or if it is common to other anti-H1 molecules.

Serum tryptase in allergic rhinitis: effect of cetirizine treatment.
Activated mast cells release a large range of potent mediators of allergic inflammation, including proteases. The tryptase serum levels were evaluated in 13 subjects suffering from allergic perennial rhinitis. Moreover the effects of cetirizine treatment on serum tryptase were studied using the UniCap™ tryptase fluoroenzymeimmunoassay. In allergic patients the serum tryptase values (M±SD: 6.1 ± 2.4 μg/L) were significantly (p < 0.02) higher than the values detected in controls (3.0 ± 1.2 μg/L). In allergic rhinitis, after antihistamine treatment, tryptase values (4.4 ± 1.8 μg/L) decreased significantly (p < 0.001). After two weeks from the cetirizine stop, the tryptase levels increased again (5.5 ± 2.6 μg/l). The results demonstrate that mast cells are constantly activated in perennial allergic rhinitis. The antihistamine treatment is effective in reducing the tryptase release from mast cells, but the mechanism of action of cetirizine is still to understand.

[Is it possible to improve survival in patients with Klatskin tumors?].
BACKGROUND: This retrospective study was undertaken to evaluate if a high resectability rate could improve the long-term outcome of patients with proximal bile duct cancer. METHODS: Between 1985 and 2001, 50 patients (34 males and 16 females) with proximal bile duct cancer were treated. The tumor site were classified according to Bismuth-Corlette's classification: 9 lesions (18%) were Bismuth type I, 23 lesions (46%) type II, 12 lesions (24%) Type IIIa, 5 lesions (10%) type IIIb and only 1 resected tumor (2%) was type IV. Thirty-six patients (72%) were considered suitable for surgery, while 14 underwent non surgical palliative procedures. Twenty patients had bile duct resection only. Ten patients had Roux-enY cholangiojejunostomy with two or three divided segmental hepatic ducts; in ten, the cholangiojejunostomy was performed with 4 or 5 divided segmental hepatic ducts. Thirteen patients had bile duct resection plus hepatectomy. Despite the curative intention of the operation, only in 19 (52.7%) patients did the histopathological examination reveal tumor-free margins. RESULTS: There was no operative mortality. Overall 1-year, 3-year and 5-year survival of the entire surgical group was 61%, 22.5% and 9% respectively. In the 19 patients treated with curative intent the survival at 1,3, and 5 years was 66%, 30% and 15%, respectively, while in the palliative group it was 45%, 15% and 0%, respectively. CONCLUSION: Only margins free from tumor may guarantee an improvement in long-term outcome. Increasing resectability improves survival and could offer a chance of better 5-year survival.

An unusual association of malignant melanoma and small cell lung cancer: case report. An eleven-year-follow-up.
The authors report the case of a patient affected by malignant melanoma and small cell lung cancer. After having underlined the rareness of this pathological association, reviewing the most recent literature, the description of the clinical case aims at opening a discussion on how the surgical treatment performed, associated to chemotherapy, brought to an unhoped-for success, also helped by an unexpected combination of events that were absolutely out of any protocol. Eleven years later, at the present follow-up, the patient shows a complete remission of both diseases.
