ABSTRACT
Teratomas are benign germ cell tumors that usually found out of their anatomical origin. Teratomas usually are found in sacrococcygeal area, gonads, mediastinum, cervicofacial region and intracranial fossa. Spinal teratomas are rare. In this study we describe a case of conus medullaris teratoma which was diagnosed based on imaging studies. The patient underwent surgery. We did bilateral laminectomy. The mass lesion had an obvious and rigid attachment to the conus medullaris. The wall of the lesion was resected as much as possible, but total resection of the lesion’s wall could not be done due to changes in neural monitoring. Previous related studies are reviewed.
ABSTRACT
Our aim was to evaluate the frequency and risk factors of posttransplant diabetes mellitus [PTDM] at our kidney transplant center, and to compare graft and patient outcomes between the kidney recipients with and without PTDM. We studied 203 kidney transplant recipients with a negative history of diabetes mellitus before transplantation. We examined them for PTDM and made diagnosis on the basis of the American Diabetes Association criteria. Measurements of plasma glucose were carried out from 3 months to 24 months after transplantation. All data including recipient and donor demographics, cause of end-stage renal disease, cytomegalovirus and hepatitis C virus antibody tests, and patient and graft outcomes were assessed in relation to PTDM. High fasting plasma glucose was seen in 24 [11.8%], 19 [9.4%], 16 [7.9%], and 13 [6.4%] patients at 3, 6, 12, and 24 posttransplant months, respectively. Moreover, impaired glucose tolerance was seen in 17 [8.4%], 16 [7.9%], 17 [8.4%], and 19 [9.4%] patients at the corresponding times, respectively. Accordingly, 39 patients [19.2%] were diagnosed to have PTDM. The mean age of the kidney recipients with PTDM was 46.5 +/- 12.3 years as compared to 38.6 +/- 13.4 years in nondiabetic kidney recipients [P = .02]. The 5-year patient and graft survival rates were not significantly different between the kidney recipients with and without PTDM. This study showed that PTDM is a common metabolic disorder in our kidney transplant patients. We recommend a less diabetogenic immunosuppressive protocol, especially for our older recipients
