Fifteen patients with very poor prognosis Hodgkin's disease in remission after MOPP/ABVD regimen, were treated with high-dose chemotherapy (HDC) and autologous marrow transplantation (ABMT) immediately after achieving complete remission (CR). Thirteen patients (86.6%) remain alive in unmaintained CR at a median time of 36 months (range 10-64 months) post-transplant. In the other two patients reasons for failure included relapse of Hodgkin's disease (one patient) and death due to interstitial pneumonitis secondary to carmustine therapy. These patients were compared with a historical control group consisting of 24 patients with the same poor prognostic factors, who achieved CR with MOPP/ABVD and did not receive other treatment. Eight out of 24 patients (33%) remain alive and well in unmaintained CR at a median time of 42 months (range 19-83 months). The administration of MOPP/ABVD combined with HDC and ABMT was not associated with an increased incidence of major toxicity. The results achieved support the early sequential treatment of a highly effective drug combination followed by HDC/ABMT that can substantially improve the likelihood of cure in these advanced stage very poor prognosis Hodgkin's disease patients. 相似文献

A patient with severe Evans syndrome received an allo-BMT from his HLA-identical sister on November, 2000. Full marrow and blood donor chimerism were achieved only after 5 donor lymphocyte infusions (DLI), and coincided with complete clinical remission and disappearence of auto-antibodies. Five years later, hemolytic anemia recurred with rapid increase of serum bilirubin to over 50 mg%: he responded to combined therapy, but died on day +17 from admission of an acute hemolytic uremic syndrome (HUS). All circulating blood cells, including erythrocytes, were 100% donor. Ex vivo cultured and expanded T and B cells from the peripheral blood were also 100% donor. The supernatants from B cell cultures, containing either IgM or IgG, did not react with a panel of erythrocytes. Thus in this typical autoimmune disease with a predominant B cell pathogenesis the donor immune system resulted “innocent of autoimmunity”. The persistence of long-lived recipient autoreactive plasma-cell lines in survival niches, still producing autoantibodies, may be hypothesized for this and similar cases. The postulated graft-versus-autoimmunity (GVA) effect was apparently not sufficient to eradicate autoimmunity in this patient. 相似文献

Background
Surgical treatment of hypopharyngeal cancers with extension to the retrocricoid region generally requires a circumferential pharyngolaryngectomy followed by a reconstruction of the removed segment of the upper digestive tract. Historically, many techniques have been used in order to achieve a safe and functional reconstruction. Jejunum interposition is generally considered the best reconstructive technique.Methods
This study examines the details of the surgical technique, the complications, the oncological and the functional results in a series of 29 consecutive patients submitted to circumferential pharyngoesophageal resection for advanced hypopharyngeal cancer followed by reconstruction with a free flap of jejunum.Results
Three of the transplants failed because of venous thrombosis. The overall success rate was 90%. There were no general complications. A good swallowing has been preserved in all our patients. All our patients where a phonatory prosthesis was positioned (20/29) were able to achieve speech following speech therapy and all were satisfied with their own capacity to communicate.Conclusions
The prognosis of hypopharyngeal tumours (18–40% at 5 years) remains poor, but jejunum autografts are being shown to be an excellent choice for the reconstruction of the cervical hypopharyngo-oesophagus offering the patient fast rehabilitation and a reasonable quality of survival. Our experience confirm that this kind of reconstruction is safe with a good results in improving oncologic controls and restoring a good quality of life. 相似文献6.

Dyslexia may be a development disturbance in which there are alterations in visual-spatial and visual-motor processing, while obsessive-compulsive disorder (OCD) is a psychiatric disease in which there are alterations in memory, executive function, and visual-spatial processing. Our hypothesis is that these disturbances may be, at least partially, the result of a crossed eye and hand preference. In the present study 16 controls, 20 OCD (DSM-IV criteria) and 13 dyslexic adults (Brazilian Dyslexia Association criteria) were included. All had a neurological examination, the Yale-Brown scale for obsessive-compulsive symptoms application and the Zazzó evaluation for laterality, abridged by Granjon. Results showed a right hand preference for 100% of controls, 84.6% of dyslexics, and 75% of OCD patients and a right eye preference for 73.3% of controls, 69.2% of dyslexics, and 35% of OCD patients. The left eye preference was significantly higher in OCD when compared with the two other groups (p = 0.01) and the left hand preference of OCD patients (25%) was also significant when compared to Brazilian population (4%) or British population (4.5%). It is possible that this crossed preference may be partially the reason for visual-spatial and constructive disturbances observed in OCD. 相似文献

Thrombosis of the arterial microanastomosis is the major reason for flap complications. Thrombus formation can occur rapidly at the site of anastomosis, or it may be delayed in developing, inducing secondary ischemia. The damaged endothelial cells and the exposed connective tissue play an important role in the molecular and cell mechanisms of coagulation and thrombosis. For this reason the early morphological changes in the endothelial cell layer after arterial microanastomoses in the rat were investigated. The results showed that the anastomotic site appeared completely sealed, with cut ends protruding into the vessel lumen. Extensive deendothelialized areas with fibrin deposition were visible between surgical microclamps on the inner surface of the artery. For this reason we believe that the damaged endothelium and exposed connective tissue elements are the primary cause of thrombin formation, platelet accumulation, and thrombosis at the anastomotic site. The reconstructive surgeon must employ a very meticulous microvascular technique to minimize damage to the vascular endothelium. 相似文献

Ultrasound (US) imaging of the spleen was considered of little use in the past and was performed only to distinguish between cystic and solid lesions. However, in the last decade due to experience acquired and the introduction of second-generation contrast agents, this technique has been re-evaluated as contrast-enhanced US (CEUS) allows detection and characterization of most focal lesions of the spleen with a high sensitivity and a good specificity. Gray-scale US presents a low specificity in splenic infarctions with a high rate of false negative cases, whereas specificity reaches 100 %, if the examination is performed using US contrast agents. Gray-scale US can provide a correct diagnosis in simple cysts, whereas CEUS is useful when cystic lymphangioma is suspected. In the study of splenic lesions, the most important problem is to differentiate between angioma, hamartoma, lymphoma, and metastasis. CEUS reaches a good specificity in the differentiation of benign from malignant splenic lesions, as hypo-enhancement in the parenchymal phase is predictive of malignancy in 87 % of cases. In conclusion, Gray-scale US and particularly CEUS are at present widely indicated in the study of focal splenic lesions. 相似文献
