Overall prognosis in younger patients with colorectal carcinoma.

Aim: Prognosis of colorectal cancer in younger patients is a controversial issue. While survival after curative resection seems not worse than in older patients, few data are available about the overall survival of younger patient with colorectal cancer irrespective of receiving a curative treatment or not. In this study we have reviewed our experience with patients under 45 years of age affected by colorectal cancer.

Thyroid carcinoma in intrathoracic goiter.

Introduction: Most cases of intrathoracic goiter can be managed by cervical incision alone. A thoracic approach may be needed when adhesions or an anomalous blood supply are present or carcinoma is suspected.

Patients And Methods: Only 44 patients out of 5263 operated on for goiter needed a thoracic incision.

Ritodrine sulphation in the human liver and duodenal mucosa: interindividual variability.

The beta2-adrenoceptor agonist ritodrine has a bioavailability of 30% due to its presystemic metabolism and sulphation is an important metabolic route. The interindividual variability in the rate of ritodrine sulphation in 100 specimens of human liver and duodenum is reported. The final concentrations of ritodrine were 2 mM (duodenum) and 20 mM (liver).

(-)-salbutamol sulphation in the human liver and duodenal mucosa: interindividual variability.

1. Salbutamol as a beta 2-adrenergic agonist used in the treatment of lung obstructive disease and premature labour. It has a bioavailability of 50% and sulphation is the main route of its metabolism.

[Colorectal carcinoma in the elderly. Assessment of prognostic factors].

Between 1976 and December 1992 a total of 80 patients aged 80 or over underwent surgery for colorectal cancer at the Surgical Clinic of Pisa University. Twelve patients died, 18 presented non-lethal complications and 48 had a normal postoperative recovery. The type of surgery did not appear to be correlated with mortality.
