Axillary lymph node dissection for intraductal breast carcinoma--is it indicated?

One hundred patients with intraductal breast carcinoma (DCIS) were treated with either mastectomy (49 patients) or radiation therapy (51 patients). All patients underwent axillary lymph node dissection (average number of nodes removed, 16) as part of their treatment. No patient had any positive axillary lymph nodes. There has been one recurrence in each treatment group (median follow-up, 27 months) and no deaths. Intraductal breast carcinoma has little potential for metastasis to axillary lymph nodes.

Hooked-wire-directed breast biopsy and overpenetrated mammography.

Six hundred fifty-three biopsies were performed for clinically occult, mammographically detected breast abnormalities. One hundred forty-seven cancers (22.5%) were found. Eighty-nine of those cancers (60.5%) were noninvasive. None of the in situ lesions had involved axillary lymph nodes. Of the 58 invasive cancers, only six (10.3%) had metastases to axillary nodes. Fifty-four patients (36.7%) were treated by mastectomy while 93 patients (63.3%) were treated conservatively, 20 by biopsy only, and 73 by lumpectomy, axillary node dissection, and radiation therapy. Only four patients (0.7%) had significant complications.

Renal vein leiomyosarcoma.

The third reported case of renal vein leiomyosarcoma is presented. Diagnosis was not made until exploratory celiotomy revealed a tumor originating from the left renal vein. The tumor was resected with margins of normal vein, and the patient was alive without recurrence 12 months after operation. Review of 65 cases of leiomyosarcoma originating in other retroperitoneal structures revealed a two-year survival rate of 20%. Therefore, we recommend consideration of postoperative adjunctive chemotherapy for renal vein leiomyosarcomas.

Blowhold cecostomy for cecal decompression.

Blowhole cecostomy is a method for achieving decompression of the distended cecum. Emphasis is placed on a McBurney-type incision, a watertight suture line joining bowel to muscle, and avoidance of opening the cecum until the suturing is done.

Caecal rupture due to colonic ileus.

Caecal rupture due to colonic ileus is rare and has a mortality rate of 43 per cent. Three new cases are presented and the 18 previously reported cases are reviewed. The disease has always occurred in association with another illness, has usually afflicted patients over the age of 55 and has only resulted when the caecum was at least 9 cm in diameter. The technique of 'blow-hole' caecostomy, a method for decompressing the distended caecum, is described.

Valley triage: an approach to mass casuality care.

Organizations prepared to respond to war, fire, flood, earthquake, or attack are essential for effective disaster control. "Valley Triage" the San Fernando Valley Medical Triage Team in Los Angeles, was formed to meet this need. The team is a mobile medical unit staffed by physicians and coordinated with civilian and military emergency services. It incorporates innovative means of communication, transportation, equipment, and training. The primary aim of Valley Triage is to provide on-site medical attention to disaster victims, and to coordinate their transfer to adequately staffed and equipped hospitals. Valley Triage offers a new approach to disaster management and can serve as a model for the development of other teams throughout the nation.

Autogenous vein bypass grafts: biological effects of mechanical dilatation and adventitial stripping in dogs.

To evaluate whether mechanical vein dilatation and stripping of adventitia at the time of harvest may adversely alter the long-term fate of autogenous vein grafts, dogs were subjected to reversed femoral vein interposition grafting with either normal veins, mechanically dilated veins, or adventitially stripped veins. Vein segments taken before grafting and veins exposed in situ but not grafted served as controls. Animals were killed at 3 months, and five vein segments in each category were evaluated for gross and microscopic changes. All grafts subjected to arterial interposition displayed marked neointimal proliferation and fibrosis of the media and adventitia. Notably, both dilated and stripped veins appeared to be similar and were indistinguishable from normal veins that had been subjected to arterial interposition for the same duration. Veins exposed in situ but not subjected to arterial flow remained essentially normal. Adverse alterations attributed to vein dilatation or adventitial stripping were not apparent and should not be invoked in the mechanism of graft failure at 3 months' duration.

Celiac artery obstruction after arteriography.

The first case of celiac artery obstruction due to selective arteriography is reported. Impairment of flow to liver and duodenum was present; but the patient recovered uneventfully with non-operative treatment. Management of this problem centers around observation, liver support, and putting the gut at rest. If non-operative treatment is failing, operation should be done, vascular reconstruction carried out, and the duodenum inspected to ensure its viability.
