66 consecutive patients with a tumor confined to the cervical esophagus underwent surgical resection. The comparison between clinical and pathological TNM stage showed a clinical understaging in 30 patients. 25 of the 56 patients who had undergone curative resection had lymph node metastases: positive mediastinal and abdominal nodes were found in 8 (32%) and 0 cases, respectively. The mean survival after curative resection of the 10 evaluable patients with metastatic periesophageal, recurrent and/or paratracheal nodes was 22.4 months; of the 6 evaluable patients with positive mediastinal nodes it was 10.3 months; and of the 5 patients with positive deep latero-cervical nodes it was 5.8 months. The 2-year actuarial survival after curative resection (in the 53 operative survivors) was as follows (according to pathologic TNM staging): Stage I (n = 3) 100%, Stage IIA (n = 17) 30%, Stage IIB (n = 3) 33%, and Stage III (n = 30) 22%. The exact location of neoplastic recurrence after curative resection was documented in 13 cases; it was in the neck in 8 cases (61%); both neck and at a distance in 3 cases (23%) and only at a distance in 2 (16%). The clinical TNM staging of cervical esophageal cancer was not in agreement with the pathological findings in nearly 50% of the cases and is, therefore, inaccurate and unreliable both for therapeutic decision-making and for prognostic evaluations. Endoscopic ultrasound, which was not used in most of the patients studied here, may improve the accuracy of clinical TNM staging. The N classification, which defines only the cervical nodes as regional nodes, appears to be arbitrary since the pathological staging showed metastatic mediastinal nodes in 32% of the N + cases, with a survival comparable to that of patients with metastatic nodes only in the neck. The prognostic value of pathological TNM staging was not confirmed in the present study since only Stage I patients had a significantly better prognosis than patients in the other stages. This may be due to the small number of patients considered or to lymph node understaging caused by the fact that most patients did not undergo mediastinal lymphadenectomy through a thoracotomy or a sternum splitting.

The use of bethanecol has recently been proposed to improve the diagnostic accuracy of esophageal manometry in identifying the origin of symptoms in patients with non cardiac chest pain. In this study we report our experience in 30 patients who underwent esophageal functional studies. Despite its low diagnostic value, bethanecol test (two subsequential doses of 50 micrograms/kg) demonstrated an excellent safety profile, there were few side effects, and patients tolerance was good. The Holter electrocardiographic study showed an isolated case of transient atrioventricular block.

Cases of familial arrhythmogenic right ventricular dysplasia (ARVD) have been reported by many authors, and a genetic mechanism of transmission has been hypothesized. Both autosomal dominant and autosomal recessive mechanism of inheritance were suggest. We present a father and a daughter affected by arrhythmogenic right ventricular dysplasia, belonging to a family with many cases of sudden death. Both of them presented with an episode of ventricular tachycardia with left bundle branch block. The clinical diagnosis was made according to electrocardiographic, echocardiographic, angionuclear and hemodynamic criteria of ARVD. The familia analysis suggest an autosomal dominant mechanism of transmission.

Three manometric characteristics of the distal oesophageal sphincter (DOS; pressure, length below the respiratory inversion point, i.e., abdominal length, and overall length) were investigated in 10 healthy volunteers and in 66 patients with typical symptoms of gastro-oesophageal reflux (GOR) disease. The aim of the work was to correlate the DOS deficiency with symptoms, endoscopic oesophagitis and with specific patterns of GOR as determined by means of 24-hour oesophageal pH monitoring. The results showed that patients with and without GOR disease cannot be separated solely on the basis of the standard manometric test, even adopting more parameters besides the traditional DOS pressure measurement. A functional defect of the DOS may be hypothesized for those patients with an apparently normal DOS on standard oesophageal manometry.
