The results of treatment of 7 patients with extensive hepatic hemangiomas are analysed. In 6 patients the diagnosis was established before the operation. The liver was resected in 4 patients. One patients with malignant degeneration of the hemangioma was inoperable, in another the hemangioma was not removed because of his old age, and still in another because the process had spread. The authors conclude that in large hemangiomas of the liver in young and middle-aged patients resection of the organ is indicated, especially if there is a destruction cavity and a rapid growth of hemangioma. The operation is not indicated in capillary, surface hemangiomas of a small size, old age of the patient, extension of the process in to the main vascular structures of the other hepatic lobe. 相似文献

A method for the prevention of thrombotic complications with heparin was developed during examination of 30 elderly and old-aged patients who underwent operation for gastric carcinoma. It was established that the therapeutic activity of heparin in plasma is maintained for 6 hours after a single subcutaneous injection of 5,000 u. Four injections of this dose of heparin ensures its continuous therapeutic activity for 24 hours in elderly oncological patients. Heparin prevention in a daily dose of 20,000 u is safe from the standpoint of hemorrhagic complications. Under clinical conditions, control of plasma heparin activity may be accomplished by means of activated partial thromboplastin time. 相似文献

In an effort to evaluate whether differences exist in the hypothalamic-pituitary-thyroid axis of depressed children, a thyrotropin releasing hormone (TRH) stimulation test was administered to 55 prepubertal subjects who were divided into three groups matched for age and sex: a depressed group (endogenous N = 15, nonendogenous N = 15), a psychiatric nondepressed control group (N = 16), and a normal control group (N = 9). Each subject was tested at two dosages of TRH, 2 micrograms/kg and 7 micrograms/kg. Increasing age and female sex were positively correlated with a greater thyroid stimulating hormone (TSH) response. TSH response to TRH was examined with subjects reclassified by severe suicidal ideation, severe aggression, and parental history of alcoholism. Results of this study are contrasted with the adult psychiatric literature. 相似文献

Long-term cognitive deficits in patients after surgery on aneurysms of the anterior communicating artery. 总被引:4,自引:2,他引:2 下载免费PDF全文

The long term recovery of a series of 27 patients who had undergone rupture and repair of an aneurysm of the anterior communicating artery was assessed using a number of neuropsychological measures. Testing took place 12 to 84 months post surgery. On the basis of the results from tests of intellect, memory, and conceptual learning, three subgroups of patients were identified: those with persuasive cognitive defects, those with evidence of residual frontal lobe damage and those who showed no evidence of dysfunction. The occurrence of cerebral vasospasm was the most consistent predictor of long term cognitive deficit. 相似文献

Pilomatrixoma are neoplasms of the hair cortical cells. They are most common during the first two decades of life and, usually, involve the head, neck, and upper extremities. These tumors may be encountered during aspiration biopsy of subcutaneous masses, and are, occasionally, confused with other neoplasms, particularly squamous cell carcinomas and epidermal inclusion cysts. The cytologic features of three such neoplasms are presented, and the characteristics that differentiate them from other benign and malignant lesions of the skin are discussed. The presence of two cell populations, the anucleated shadow cells and the basaloid cells, which lack nuclear features of malignancy, is fairly specific for pilomatrixoma. In addition, the specimens obtained from aspiration may be misinterpreted as originating from a hyperplastic lymph node in view of the intense chronic inflammatory and foreign body reaction seen in the background. Calcific deposits that lack lamellations, unlike psammoma bodies, help in establishing the definitive diagnosis of these benign neoplasms. 相似文献

Thirteen patients with a malignant germ cell tumor of the ovary have been treated with a combination of vinblastine, bleomycin, and cisplatin (VBP). In 12 patients a complete remission was reached, which was maintained in 10 of these patients. One patient with large tumor residues and a partial remission became CR after surgery. The tumor recurred in 2 patients after 6 and 27 months. Overall, 11 of these patients are in long-term remission, from 14 to 84 months after the start of treatment. VBP is an effective treatment for malignant germ cell tumors of the ovary, even in patients with large tumor residuals. 相似文献

This case report demonstrates how extracting a maxillary deciduous canine affects the eruption path of a labially displaced ectopically erupting permanent canine. A long-term follow-up is presented, and the biologic mechanisms are discussed. 相似文献
