Background: This work is aimed at comparing mucinous colorectal adenocarcinomas (MUC) and non-mucinous colorectal adenocarcinomas (non-MUC), and at verifying the existence of two different subgroups of MUC, in terms of clinicopathological features, chromosomal alterations, and outcome, in a geographical area where mucinous colorectal cancer resulted as being very frequent.
Methods: One hundred and fifty-six unselected patients who underwent curative colorectal resection for sporadic colorectal cancer over a 4-year period were evaluated for histological classification as to MUC and non-MUC subtype, for microsatellite instability (MSI) using six microsatellite markers, and for the presence of p27, Fhit, and cyclooxygenase-2 (Cox-2). Molecular data, immunohistochemical results, recurrence frequency, and patient survival were analyzed statistically in relation to histological subtypes.
Objective: Our aim was to identify early predictors of poor neurodevelopmental outcome and of subsequent epilepsy in very early preterm and late preterm newborns with neonatal seizures.
Study Design: Fifty-one preterm infants with gestational age (GA)
Objective: To investigate whether changes in tubuloglomerular feedback (TGF) dependent upon the tubular effects of buffering anions affect the renal haemodynamic response to L-arginine in healthy (control) individuals and patients with essential hypertension.
Methods: Mean arterial pressure (MAP), glomerular filtration rate (GFR), renal blood flow (RBF) and fractional excretion of sodium (FENa), chloride (FECl) and lithium (FELi) were measured in 10 control individuals and 10 hypertensive patients during two 3-h infusions of 0.012 mmol/kg per min L-arginine buffered with either HCl or citric acid.
Background: Rates of cardiovascular morbidity and mortality are greater in heavy alcoholics than in either teetotallers or light-to-moderate drinkers.
Objective: On the assumption that factors leading to atherosclerotic damage remain operative even after long-term alcohol withdrawal, we studied the possible mechanisms of raised cardiovascular risk in former heavy alcoholics.
Methods: Forty-two apparently disease-free, normotensive alcoholics detoxified for 37.
Background: The role of the loss of p27 protein expression in the oncogenesis of colorectal cancer is still in debate. In this study, we prospectively examined the immunohistochemical expression of p27 in 108 consecutive colorectal cancers, and we analysed the relationship with the results, the clinicopathological data, microsatellite instability (MSI) and other genetic alterations of tumours.
Methods: Unselected patients (108) who underwent curative colorectal resection for sporadic colorectal cancer in a three-year period were evaluated for MSI using 6 microsatellite markers, and for the presence of p27, p53, Fhit, Mlh1 and Msh2 proteins by means of immunostaining.
An association between Graves' disease (GD) and chronic hepatitis C (C-HC) has been observed both in the presence and the absence of recombinant interferon-alpha (rIFN-alpha) treatment. rIFN-alpha-induced GD is characterized by suppressed thyroid-stimulating hormone levels; normal or elevated free triiodothyronine (FT3) and free thyroxine (FT4) values; the presence of thyroid peroxidase antibodies, antithyroglobulin antibodies, and thyroid receptor antibodies; and high iodine thyroid uptake. In contrast, GD developed during C-HC without rIFN-alpha is less clearly defined.

The aim of this study is to report the electrophysiological features of patients showing typical AVNRT induced through SDNC.
Methods And Results: Among 461 consecutive patients with typical AVNRT submitted to radiofrequency catheter ablation (RFCA), seven patients (1.
Objective: Treatment with interferon (IFN) of patients affected by chronic hepatitis C (CH-C) may produce alterations in thyroid function, such as hypothyroidism, Graves'-like hyperthyroidism and destructive thyrotoxicosis (DT). IFN-induced DT is characterized by suppressed serum TSH levels, normal or elevated FT4 and FT3 concentrations, with the presence or absence of thyroid peroxidase antibodies and antithyroglobulin antibodies, the absence of thyroid receptor antibodies and radioactive iodine uptake suppressed or <5%.
Design: IFN-induced DT is a mild clinical disease, because thyroid-destructive processes last for a short time and involve a small portion of the gland.
Background: Stimulated sympathetic nervous system, renin-angiotensin-aldosterone system, vasopressin, and cortisol are thought to affect blood pressure in early withdrawal of alcoholics. Hyperactivity of sodium-retaining systems with consequent volume expansion also could interact with sodium sensitivity as previously found in long-term withdrawing alcoholics.
Methods: To investigate this hypothesis, blood pressure and sodium balance were measured during the first 8 days of withdrawal in 18 chronic alcoholics on a 150 mM Na diet.
The stability over a 12-year period of several coronary heart disease (CHD) risk factors was evaluated in 348 individuals who had remained healthy following baseline measurements made of the same variables in 1981. CHD risk factors evaluated were fasting and post-glucose challenge (120-minute) plasma glucose and insulin concentrations, plasma triglyceride (TG), low-density lipoprotein (LDL) and high-density lipoprotein (HDL) concentrations, and the ratio of LDL/HDL cholesterol concentrations. Approximately 40% to 60% of individuals in the highest CHD risk quartile (or lowest in the case of HDL cholesterol concentrations) in 1981 were still at highest risk in 1993.
