[Percutaneous pigtail catheter drainage of peripheral breast abscesses]. / Il drenaggio percutaneo con catetere pigtail degli ascessi mammari a localizzazione periferica.

Almost all peripheral non-lactational breast abscesses are staphylococcal in origin and so percutaneous drainage can be a valid alternative to surgical incision. Percutaneous drainage was performed in eight patients with one or more abscesses. A pigtail catheter was inserted only in foci greater than 3 cm. The results were good in 9 out of 10 purulent collections; one recurrence was observed in the smallest focus. All patients but one underwent local anesthesia and were managed as outpatients.

Diabetic fibrous breast disease: a clinical entity that mimics cancer.

Three typical cases of fibrous mastopathy associated with diabetes mellitus are described. The histological change is a connective-tissue overgrowth with vasculitis and some proliferation of duct epithelium. The clinical changes are indistinguishable by physical or radiographic findings from malignancy. In young patients with long-standing diabetes the presence of one or more suspicious clinical and imaging findings can suggest the presence of this lesion but a surgical biopsy or, at least, a close follow-up is required.

[Unilateral edema of the breast secondary to congestive heart failure. Report of 2 cases]. / Edema monolaterale della mammella secondario ad insufficienza cardiaca congestizia. Osservazione di due casi.

This report describes two cases of diffuse unilateral edema and skin thickening of the breast, that mimics an inflammatory carcinoma, caused by congestive heart failure. The clue to the correct diagnosis of congestive enlargement of the breast is the presence of 'pitting' edema, which is not found in malignant breast edema. Resolution of the breast enlargement usually occurs when the heart failure is properly treated.

Progressive pneumoperitoneum in the management of giant incisional hernias: a study of 41 patients.

Forty-one patients (17 men and 24 women) were treated with progressive pneumoperitoneum before repair of giant incisional hernias. The pneumoperitoneum was induced using nitrous oxide gas and a laparoscopic insufflator, and was topped up every other day for a mean of 5.5 days with a total injection of 23.2 litres of nitrous oxide. The pneumoperitoneum was well tolerated in 30 patients, caused a mild temporary pain in 10 patients and a sharp pain in one patient; no serious side-effects occurred. All the patients underwent surgery to repair their hernias, 40 patients were available for follow-up for a mean of 25.3 months, only two hernias recurred both within 4 months of the operation.

Prognostic correlations of operable carcinoma of the rectum.

Various histologic factors correlated to survival were studied in 124 patients radically operated on for rectal carcinoma in order to establish valid prognostic criteria. The total survival rate after five years was 63 percent, while in stage B1 it was 89 percent, in B2, 61 percent, and in C1, 47 percent (P less than 0.05). With regard to histotype, the survival was 83 percent in the papillary subtype of adenocarcinoma, while in the tubular subtype it was 62 percent, and 29 percent in the mucinous type (P = not significant). Vascular invasion negatively affected survival (41 percent); however, when there was no invasion, the prognosis was better (71 percent) (P less than 0.01). In evaluating histologic grading and lymphoglandular reactivity, the difference in survival rates was not statistically significant. The marked peri- and intratumoral lymphocytic infiltration gave a very good prognosis (92 percent) contrary to when reactivity was moderate (59 percent) or even absent (51 percent) (P less than 0.01). Finally, the expanding type tumor, with reference to Ming's classification of gastric carcinoma, had a much better prognosis (75 per cent) than the infiltrative type (40 percent) (P less than 0.01).
