Free flap reconstruction of complex defects has revolutionized cancer and trauma treatment and offers a reliable and efficient method for reconstructing tissue defects. We analyzed the donor, flap, and systemic complications in an aging group and in a group of younger patients to identify whether age is an important factor in complication rates. This study was a retrospective review of the medical records of 43 consecutive patients who underwent free flap reconstructions. Patients were divided into two groups according to age (group A: younger than 60 years, group B: 60 years or older). We analyzed the free flap types and donor site, flap, and postoperative systemic complications. Statistical analyses were performed to determine the influence of age on complication rate. Donor site complications developed in three cases in group A and in three cases in group B. Flap complications occurred in 17 cases in group A and in 5 cases in group B. Systemic complications occurred in two cases in group A and in five cases in group B. Age did not have a statistically significant impact on free flap complications, and old age was not a risk factor for free flap surgery. 相似文献

Previous reports of a solitary metastatic hepatocellular carcinoma have been rare. Because this tumor has a different treatment modality and prognosis, an accurate differential diagnosis is essential. Here we report a rare case of a solitary chest wall metastasis from unknown primary site of hepatocellular carcinoma. It involves a 51-year-old man who was admitted to our hospital because of a palpable left upper chest wall mass. The mass was resected and pathologic examination confirmed a diagnosis of metastatic hepatocellular carcinoma. Despite our investigation, no evidence was found that indicated the primary origin of the hepatocellular carcinoma. Four months later, the patient was admitted again because of spinal cord compression at the third and fourth thoracic vertebrae. Emergent decompressive laminectomy was performed and microscopic features revealed the same pathology as the initial chest wall mass resected 4 months earlier. After one year, a follow-up abdominal computed tomography (CT) still revealed no evidence of primary hepatocellular carcinoma. 相似文献

Well-differentiated epithelial thyroid cancer management in the Asia Pacific region: a report and clinical practice guideline. 总被引:1,自引:0,他引:1

CONTEXT: Thyroid cancer is among the 10 most common malignancies in populations in the Asia Pacific region, where access to various relevant health care resources varies widely. OBJECTIVE: An expert consensus conference was held to define regional patterns of practice and guidelines for optimal management of well-differentiated epithelial thyroid carcinomas. RESULTS: Practice patterns vary from country to country, as would be anticipated form their variety of ethnic and racial populations, health care systems, economies, and cultures. Thyroid cancer care is provided by a number of medical and surgical specialists, usually including endocrinologists. The thyroid surgical skills, experience, and outcomes vary widely in the region. Radioiodine is available, to a greater or lesser extent, is almost all countries. Laboratory services for thyroid function monitoring are universally accessible; thyroglobulin assays are available in most countries. Recombinant thyrotropin is approved for use in only two countries, but can be accessed in some others on a "named patient" compassionate need basis. Access to advanced imaging, for exampke, positron emission tomography (PET) scanning, is limited to a few countries. CONCLUSIONS: In light of these realities, appropriate strategies for initial treatment and postoperative monitoring of patients with thyroid cancer have been defined, and these are presented and discussed. 相似文献

Primary effusion lymphoma (PEL) is a recently recognized disease that occurs most often in immunosuppressed patients, either with human immunodeficiency virus (HIV) or in the posttransplantation setting, and it occasionally occurs in nonimmunosuppressed patients. Patients present with lymphomatous effusions in serous cavities--pleura, pericardium, or peritoneum--without any identifiable tumor mass. PEL rarely responds to systemic chemotherapy, and the prognosis is poor, with a median survival time of less than 6 months for most cohorts. A standard treatment for PEL has not yet been identified. We describe a patient with HIV-seronegative PEL who relapsed after combination chemotherapy and then underwent successful treatment with high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT). The treatment was well tolerated, and the patient has been in remission for 12 months after HDC and ASCT. 相似文献

To investigate shear stress-induced platelet activation, the cone-plate viscometer or the Couette rotational viscometer has been widely used. In a previous report, it was shown that shearing platelet-rich plasma using a Couette rotational viscometer could lead to an increase in pH by CO(2) release. However, any clear mechanism has not been provided. In this study, we examined whether shearing cell free plasma only using a cone-plate viscometer can also induce pH increase and studied the underlying mechanism of shear-induced pH increase by directly measuring total CO(2) (T(CO(2))) and CO(2) tension (P(CO(2))). When human plasma was sheared using a cone-plate viscometer, the pH of the human plasma increased time- and shear rate-dependently. Although T(CO(2)) of human plasma was not affected, P(CO(2)) was decreased by shearing, indicating that the decreased P(CO(2)) is associated with a pH increase of plasma. In addition, the pH of bicarbonate-containing suspension buffer was also shown to be increased by shearing; suggesting that the platelet studies using suspension buffers containing bicarbonate could be affected similarly. The effects of pH changes on shear stress-induced platelet activation were also investigated in the same in vitro systems. While shear stress-induced platelet aggregation was not affected by the pH changes, P-selectin expression was significantly increased in accordance with the pH increase. In conclusion, shear stress using a cone-plate viscometer induces pH increase in plasma or bicarbonate-containing suspension buffer through a P(CO(2)) decrease and the pH changes alone can contribute to platelet activation by enhancing shear stress-induced P-selectin expression. 相似文献

Cardiac resynchronization therapy (CRT) has been proven its value in adult patients with congestive heart failure of low ejection fraction and wide QRS duration. Contrast to adult patients, CRT has been rarely applied for young patients. We report on a 9-yr-old boy with progressive left ventricular (LV) dilatation and dysfunction following chronic VVI pacemaker therapy for congenital complete atrioventricular block associated with maternal anti-SSA/Ro and SSB/La antibody. His LV dysfunction was improved after epicardially established CRT. 相似文献
