Perioperative surgical stress makes various metabolic and endocrinologic changes that may influence the postoperative outcome. These changes, so-called, "surgical stress responses" ar hyperglycemia, lipolysis, negative nitrogen balance due to proteolysis, and changes in the hormonal secretion, e.g. increased release of ACTH, prolactin, cortisol, catecholamine, and so on. To prevent these stress responses, many studies reported some kinds of effective methods. In these study we used general anesthesia combined with epidural blockade with local anesthetic(bupivacaine) and narcotic(fentanyl) mixture via epidural catheter for the total abdominal hysterectomy and the postoperative pain control(group II). We measured serum prolactin and cortisol concentrations by time-resolved fluoroimmunoassay and glucose concentrations by routine glucose oxidase method and scored the degree of postoperative pain and compared the results with those of group I, given general anesthesia during surgery and nalbuphine intramuscular injection for postoperative pain control. The results were as follows. 1) Serum prolactin concentrations were increased during the operation in both groups. 2) Serum cortisol concentrations were increased during and after the operation in both groups but were normalized sooner in group II. 3) Serum glucose concentrations were increased during and after the operation but were normalized sooner in group IL 4) The three measurements showed significant differences between the two groups during and on the first postoperative day. 5) The pain scores were significantly lower in group II untill the third postoperative day. According to the results, we concluded that serum prolactin concentration could be as much valuable index to surgical stress response as serum cortisol concentration and that the method of epidural blockade combined with general anesthesia for the surgery and postoperative pain control via epidural route could prevent or alleviate the stress response more effectively.

PURPOSE: To demonstrate and evaluate the value of MRI findings of the TSH(Thyroid-Stimulating Hormone, TSH, Thyrotropin)-secreting pituitary adenoma. MATERIALS AND METHODS: The authors reviewed retrospectively the MR images of 4 patients with TSH-secreting pituiatary adenoma. Evaluation of the anatomical location, signal characteristics, enhancement patterns, size, shape and circunferential changes were made. RESULTS: No characteristic common MR findings in size, shape, signal intensity, and circumferential changes of TSH-secreting pituiatary adenoma waere observed among 4 cases(size; 5x7 mm to 10x11 mm, shape;ovoid to round, signal intensity;high in 1 case on T1 and T2WI, isosignal intensity in the other 3 cases, circumferential change; stalk deviation in 1 case, no stalk deviation in 3 cases). But, the tumors were centrally located at the anterior pituitary gland and showed relatively homogeneous signal intensity on MR images of all 4 patients. CONCLUSION: We conclude that centrally-located mass at the anterior pituitary gland with homogeneous signal intensity on MR image may be suggestive of the TSH-secreting pituitary adenoma, although the MR findings are not specific for the disease.

PURPOSE: A pancreaticoduodenectomy is the procedure of choice for managing a periampullary malignancy. This is a complex procedure accompanied with some morbidity. In order to improve postoperative clinical results, we tried to apply a binding pancreaticojejunostomy and Endo GIA stapler during pancreaticoduodenectomy. According to the clinical outcomes, compare this trial with a conventional procedure. METHODS: We evaluated retrospectively clinical results of 30 patients who had received pancreaticoduodenectomy from Jan. 2003 to Dec. 2004 in the Pusan National University Hospital. These cases were divided into two groups; Group I comprised of 16 patients receiving this procedure and Group II comprised of 14 patients receiving conventional procedure. RESULTS: There were some differences in the mean operation time and the amount of blood loss between two groups, but significant difference only in an aspect of blood loss (P=0.042). Postoperative complications were as these: Group I, pancreatic fistula was in 12.5%, intraabdominal bleeding in 6.2%, wound infection in 12.5%; Group II, pancreatic fistula was in 35.7%, intraabdominal bleeding in 21.4%, wound infection & intraabdominal abscess in 7.1%. In Group I, there was a lower morbidity rate than in Group II, but there was a significant difference in the development of a pancrea-tic fistula as a pancreatic parenchymal texture (P=0.021). CONCLUSION: Although there was a small number of cases, it appears that a pancreaticoduodenectomy with the application of a binding pancreaticojejunostomy and Endo GIA stapler can produce good results, also need to get more clinical results.

Two cases of spontaneous remission in acute promyelocytic leukemia are reported. They had precedent febrile episodes and subsequent resolution of all clinical and hematological abnormalities occurred after supportive care including administration of various antibiotics. Their remissions lasted for 12 and five months respectively, when they relapsed.

Positron emission tomography(PET) is a diagnostic method that creates high resolution, 3-Dimentional tomographic images of the distribution of positron emitting radionuclides in human body. Computed tomography(CT) and magnetic resonance imaging(MRI) are routinely used to delineate the presence and extent of primary and metastatic oral and maxillofacial malignancy. Because the CT and MRI criteria for malignancy depend upon morphology, these imaging techniques have limitations in their ability to identify malignant tissue when fascial planes are distorted or destroyed. PET has the advantage of imaging metabolic changes that appear to be linked to malignancy. Recently, PET has shown promise in the early detection of primary and metastatic oral and maxillofacial canter and has been used to evaluate the tumor response to chemotherapy and radiotherapy. We report cases of diagnosis of oral and maxillofacial cancers and review the literatures to determine whether PET is effective in identifying oral and maxillofacial tumors.
