Management of chondroblastoma: retrospective review of 28 patients   总被引:3,自引:0,他引:3  
Background This study retrospectively reviewed 28 patients who presented with chondroblastoma in our hospital during the period March 1986 to February 2006. We investigated factors associated with local recurrence of the tumors after surgery. Methods We recorded the patients' sex and age, the location of the pathology, imaging studies (status of growth plate and activity of lesions), histological findings, and treatment outcomes. Results Pain was the presenting symptom in all patients. The tumors were generally located in the epiphyses or apophyses of long bones, especially in the proximal humerus (9 patients), proximal tibia (7 patients), and proximal femur (5 patients). Our preferred treatment method was generally aggressive curettage of the lesion followed by bone grafting. There was local recurrence in six patients. A secondary aneurysmal bone cyst was present in two patients. Conclusion Aggressive curettage and bone grafting resulted in local control in most patients. Tumor recurrence was not statistically associated with age, sex, growth plate status, tumor location, or tumor activity. The only parameter associated with increased local recurrence was previous surgery for chondroblastoma in the same location.  相似文献

Short-segment Hirschsprung's disease and idiopathic megacolon are clinically similar. In addition to histological examinations, manometric studies were found to be useful in differentiating between these two forms of megacolon. Anorectal myectomy is not only effective in treating short-segment Hirschsprung's disease but also in a number of patients with idiopathic megacolon. Anorectal myectomy should be considered in patients suspected of having short-segment Hirschsprung's disease and also for idiopathic megacolon, if medical and psychiatric measures fail.  相似文献

A 5-year-old child sustained blunt trauma to the cervical trachea.Diffuse subcutaneous emphysema of the neck and thorax developedrapidly. Anaesthesia was induced with halothane through a face-pieceand the patient breathed spontaneously until the lesion hadbeen evaluated. This course is advocated in the management ofsuch injuries.  相似文献

A patient who suffered 30 per cent third-degree burns about one week after becoming pregnant was treated with Sulfamylon (mafenide) and silver nitrate for 20 weeks until abortion. Pathological examination of the fetus showed no abnormalities, suggesting that Sulfamylon and silver nitrate are safe drugs for the treatment of burns sustained in the first trimester of pregnancy.  相似文献

A patient with ileal conduit and recent dilation of the left upper collecting system had flexible fiberoptic endoscopy of the ileal loop. The entire lumen of the intestinal conduit and the ureteroileal anastomosis were visualized. In addition retrograde pyelography and direct vision biopsy of a tumor in the ureter were performed.  相似文献

Abstract: Generally, the incidence of peritonitis in maintenance peritoneal dialysis programs is calculated as a percentage of the total number of treatments or as the number of episodes per patient-months. Both statistical methods give the wrong impression that peritonitis is seldom observed. However, peritonitis is still the major and unsolved challenge to successful long-term peritoneal dialysis. The lack of a standard and homogeneous definition of peritonitis is another critical point that prevents a rational interpretation of the published experiences. In the present study, dialysate cell counts of > 1,100 cells/mm3 were assumed to be the first sign of peritoneal infection. As long as more signs and symptoms are required for recognizing peritonitis (fever, abdominal pains, positive cultures), the statistical probability of making such a diagnosis shows the characteristics of a Poisson distribution. It is concluded that in long-term peritoneal dialysis, the currently used statistical methodology for evaluation of the incidence of peritonitis, including the clinical definition of this complication, is misleading. Dialysate cell counts appear to be the more sensitive sign for early diagnosis of peritonitis.  相似文献

Five semen characteristics (count, motility, normal forms, bovine cervical mucus penetration, and ATP) were evaluated in patients attending the infertility clinic. Multiple regression analysis indicated that the only characteristic independently affecting ATP concentration was sperm count, whereas motility and percent normal forms had no additional contribution to ATP level. Penetration into bovine cervical mucus did not depend on ATP levels. Comparison of semen characteristics in the same group between patients who have impregnated their wives and those who have not indicated that with respect to count, motility, morphology, and ATP the only sperm characteristic independently predicting fertility was motility. ATP measurements have limited value in the evaluation of semen quality.  相似文献

Cleft sternum is a rare disturbance of unknown origin in the normal central midline fusion. Three cases of upper cleft sternum are reported here, one associated with a pericardium to the skin sinus tract. Surgical correction of this anomaly in the neonatal period is advised, whether the infant is symptomatic or not. Simple closure of the defect during the first month of life avoids the more complex reconstruction necessary in older children.  相似文献

Juvenile breast hypertrophy in a 12-year-old girl was treated by bilateral reduction mammoplasty (amputation type) with free transplantation of the areolae and nipples and removal of 8,200 g of breast tissue. Eleven months later, subcutaneous mastectomy with subpectoral tissue expander insertion was performed due to recurrent enlargement of the breasts, with removal of an additional 5,000 g. Three months later, silicone prostheses replaced the tissue expander, with reconstruction of areolae and nipples. One year later, a good result was observed and the breasts have been satisfactorily reconstructed.  相似文献

The peritoneum has been classically considered to be an inert passive membrane. Previous studies demonstrated the presence of fixed anionic charges at the level of the peritoneal microvasculature and the subserosal interstitium. The present study describes the selective distribution of fixed anionic charges in the mesothelial cell plasmalemma and organelles as well as in the submesothelial basal lamina of rat and mice visceral, parietal and diaphragmatic peritoneum. These data support the idea that the peritoneum should be considered a negatively charged biological dialyzing membrane with selective capabilities. Therefore, transperitoneal transfer of charged solutes cannot be analyzed just on the basis of their molecular weight, size and shape.  相似文献
