Clinical importance of tumour markers in the diagnosis of squamous-cell carcinoma of the esophagus.

In order to evaluate the diagnostic value of three tumour markers, CEA, CA 19-9 and TA4-scc, 50 patients affected by squamous-cell carcinoma of the esophagus were studied together with 70 normal controls and 22 patients affected by benign esophageal pathologies. The three tumour markers were assessed in all patients and data were evaluated statistically in order to reveal their sensitivities, specificities and diagnostic values. It was concluded that further studies should be carried out on the marker TA4-scc given its high specificity and sensitivity towards esophageal neoplasias at a relatively early stage.

Gastric angiography: data for oesophagogastroplasty.

A report is presented on an angiographic study of the gastric arterial system conducted on 20 human stomachs taken from cadavers during routine autopsies. The aim of the study was to define the anatomical bases for the supply of blood to the isoperistaltic gastric tubule in oesophagogastroplasty operations. The study reveals that on its own the right gastroepiploic artery cannot ensure adequate vascularisation of the gastric fundus. The importance of pressuring the right hand section of the vascular arch along the small curve was also noted and is due to the constant presence of major anastomoses at antral level with the right gastroepiploic artery. The study also revealed the constant presence of a direct intramural anastomotic circulation between the right and left gastroepiploic arteries.

Respiratory function during oxygen administration in chronic obstructive pulmonary disease.

Patient with severe chronic obstructive pulmonary disease (COPD) can develop respiratory muscle weakness and fatigue. Arterial hypoxemia can predispose to this condition. To assess whether O2 administration improved respiratory muscle function and respiratory pattern in COPD 11 patients with chronic hypoxemia were examined. Each patient was first submitted to respiratory function studies, including lung volumes, in normal and recumbent position, respiratory frequency, Ti/Te, Ti/Tot, maximal inspiratory and expiratory pressures (Pimax, Pemax) and arterial gas analysis breathing room air. All these tests were repeated during oxygen Administration through a nasal cannula. The arterial PO2 improved from 50 +/- 7 mmHg to 81 +/- 28 mmHg but the breathing pattern, Pimax and Pemax as well as lung volumes remained unchanged. It is concluded that oxygen, in short term administration, doesn't influence respiratory pattern and muscle function.

Cardiac arrhythmias following lung resection in patients treated and untreated with digitalis prophylaxis.

Cardiac arrhythmias and failure following lung resection in patients treated and untreated with digitalis prophylaxis have been evaluated. In 82 patients without digitalis (1st group) 11% tachyarrhythmias and 5.7% cardiac failures were noted. In 100 patients treated with digitalis (2nd group) 7% arrhythmias and no cardiac failures were registered. Among cardiac complications only one death in the first group was observed. The mean period of incidence of arrhythmias appears dilated in the digitalis group (3rd vs. 5th postoperative day) and this could be attributed to the early suspension of the drug.
