Endoscopic ultrasonography in the diagnosis of gastrointestinal amyloid deposits: clinical case report.

A case of systemic amyloidosis of the digestive tract is described here, with particular attention to the endoscopic ultrasonography aspects, characterized by a wide-spread thickening of the stomach and rectum walls, with loss of the normal layer structure of the mucosa and submucosa. Endoscopic ultrasonography, especially in pseudotumoral forms, may contribute to the differential diagnosis from neoplastic lesions, in which the wall thickening appears to be localized and accompanied by parietal infiltration.

Comparison between echo-guided fine-needle aspiration cytology and microhistology in diagnosing pancreatic masses.

Echo-guided fine-needle aspiration biopsy of pancreatic masses is a well-established diagnostic procedure. However, there is no consensus as to the superiority of cytology or microhistology. We compared the results of cytology and microhistology in 50 consecutive patients who underwent fine-needle aspiration biopsy for pancreatic masses. Aspirates were positive for malignant disease in 42 patients; the other eight had chronic focal pancreatitis. In the 42 cases of cancer, cytology provided conclusive results in 40 (95.2%); sampling was inadequate in two. Microhistology proved accurate in 30 cases (71.4%); insufficient tissue was obtained in 12, giving a statistically significant difference in favor of cytology (P < 0.01). In the eight patients with benign disease both techniques ruled out malignancy; in five microhistology gave further indications confirming suspected chronic pancreatitis (fibrosis, lymphocyte and histiocyte-cell infiltrate). Our results show that cytology is the method of choice in diagnosing pancreatic carcinoma. Microhistology can be a useful adjunct in patients with suspected chronic pancreatitis.

[Hydatid choleperitoneum: a rare complication of hepatic hydatid disease].

The authors report their experience relative to hydatid choleperitoneum which is a rare complication of hydatid hepatic disease (one case of 236 operated). They underline how such pathology constitutes a clinic and anatomopathological case, well characterized and different from those offered by other complications of this hepatic disease. They draw attention moreover on how preoperative diagnosis is often difficult and consequently how the surgical therapeutic technique requires a very careful examination of anatomic relations of the lesion and recognize, as a chiefly foundation, a radical treatment of hepatic disease and whenever possible, the removal of the pseudomembrane of encystment.

[Tracheostomy: indications, techniques, and complications].

The authors report their experience relative to 46 tracheostomies performed over a 10-year period. In 6 cases the indication for a tracheostomy was a post-traumatic respiratory failure; in 20 cases a chronic respiratory insufficiency, in 6 cases a malignant neoplasm of the larynx; in 10 cases a postoperative respiratory insufficiency; in 4 cases for tongue and/or neck wounds. The authors stress the importance of a correct indication, the use of large volume-low pressure cuffs and an appropriate surgical technique to prevent complication of tracheostomy.
