摘要:

We surveyed 13 proven cases of neuro-otologic tumors to determine the value of audiometric and radiologic studies. Angle myelography was positive in 100% of cases tested. CT scan with intravenous enhancement was positive in 91% of cases tested. Stapedial reflex decay or tone decay was positive in 100% of cases tested. A practical management plan is suggested for follow-up of patients with vertigo, unilateral tinnitus, and hearing loss.

摘要:

The clinical course of implanted intraocular lenses is frequently complicated by the formation of deposits or “precipitates” on the lens surfaces. These lesions are related to the amount of inflammation in the eye, the use of pilocarpine, and the presence of lens cortex in extracapsular procedures. Corticosteroids cause the lesions to diminish or disappear. Similar lesions seen in the course of lens implantation in laboratory animals are found on histologic examination to be accumulations of inflammatory cells. In the chronic state the cells are macrophages, epithelioid cells, and giant cells, accompanied in the early stages by acute inflammatory leukocytes. The relationships between these cells, inflammation, the presence of the foreign body, and the chemistry of methyl methacrylate are difficult to sort out.

摘要:

Phlebography is a useful examination if a standardized technic is carefully used, and it can be relied upon to diagnose acute thrombophlebitis definitively or to rule it out. The 200 consecutive phlebograms reviewed produced no mortality or pulmonary embolism, and only minimal morbidity. Phlebograms are also useful in mapping before varicose vein surgery and in distinguishing the leg swelling of the postphlebitic state from that of lymphedema.

摘要:

Acalculous cholecystitis occurred in six patients after trauma and burns. The majority developed signs and symptoms similar to acute calculous cholecystitis. All were treated by cholecystectomy after traditional conservative treatment failed. All had either gangrenous changes or focal necrosis of the gallbladder. Postoperative recovery was uniform. Acalculous cholecystitis occurs in 0.5% of large series of injured or burned patients. Delayed recognition led to a high mortality, reported as 24% overall with 10% related to gallbladder disease. Although cholecystostomy has been advocated, it appears that holecystectomy, when feasible, affords the best overall results.

摘要:

The records of patients with primary gastric lymphoma and sarcoma treated at M. D. Anderson Hospital and Tumor Institute between 1945 and 1975 were reviewed. Weight loss, abdominal pain, nausea, and vomiting were the most common presenting symptoms, while palpable abdominal mass was the most common sign. The lymphomas were predominantly located in the distal portion of the stomach, in contrast to the sarcomas, which were commonly located in the body and the proximal portion of stomach. Curative gastric resection was performed in 96% of patients with lymphoma and in 67% of patients with sarcoma. Diffuse histiocytic lymphoma and leiomyosarcoma were the most common histologic types. Patients with lymphoma survived significantly longer than patients with sarcoma (median 75 vs 22 months,P= 0.009). Adjuvant radiotherapy seemed to improve the survival of patients with lymphoma, while curative gastric resection provided the only hope for long-term survival for patients with gastric sarcoma. The place of adjuvant chemotherapy after curative resection of gastric lymphoma and sarcoma remains to be investigated.

摘要:

Carcinoma of the esophagus is found more commonly in association with head and neck tumors, lye stricture, achalasia, and Barrett esophagus than in the general population. Our experience with these associated entities in a population of 680 patients with carcinoma of the esophagus is reviewed. Carcinoma of the esophagus has traditionally had a very poor prognosis which continues to the present. Routine periodic use of double contrast esophagography is advocated to screen populations containing these associated high-risk entities. This may ultimately increase survival through diagnosis of earlier stages of carcinoma of the esophagus.

摘要:

Morphologic type is not generally included in the study of cancer risk factors. In breast cancer, attention is being given to age at diagnosis. In this study cases were analyzed by morphologic type as well as age at diagnosis for occurrence of bilateral disease and for family history of breast cancer. Of the morphologic types which were more frequent in younger patients—lobular in situ, medullary, and intraductal comedo—only lobular in situ had an increased frequency of bilaterality (fourfold increase). Of these, only patients with intraductal comedo reported familial breast cancer more frequently than the average. Lobular infiltrating carcinoma is diagnosed more frequently in elderly patients and is associated with 2.6 times more bilaterality and increased familial risk. Diagnosis at age 45 to 54 is also associated with increased bilaterality, but the diagnosis of lobular carcinoma has much stronger association with bilaterality than early age at diagnosis. Because of the high risk of bilaterality in lobular neoplasia and in those with a family history of cancer occurring before the menopause, bilateral biopsies and subsequent screening for malignancy should be done in these women.
