OBJECTIVES: The purposes of this clinical study were 1) to assess 5-year survival rates in 195 patients with locally invasive cervical cancer(stage Ia-IIb) treated by surgery, neoadjuvant chemotherapy+surgery and postoperative radiation in selected cases, 2) to evaluate the prognostic factors affecting the survival rate, and 3) to get helpful information for the better treatment. METHODS: A retrospective analysis was conducted of 195 patients. They were diagnosed and operated on during the period of Jan. 1988 - Dec. 1993 in Dept. of OB/Gyn, Pusan Paik Hospital, Inje Medical School. The 5-year survival rates were estimated using the Kaplan-Meier method, and prognostic factors were assessed using Wilcoxon test. RESULTS: The 5-year survival rates for FIGO stages Ia, Ib, IIa, and IIb were 100, 86.1, 76.9, and 81.1%, respectively. Factors that affect the 5-year survival rates were clinical stage(P=0.0001), cell type(small cell vs other, P=0.0001), depth of invasion(< or = 5 mm vs >5 mm, P=0.0013), tumor size(< or = 3 cm vs >3cm, P=0.0035), and lymph node metastasis(0 vs 1 vs more than 2, P=0.0001). There was no difference in 5-year survival rates between without neoadjuvant chemotherapy group and with neoadjuvant chemotherapy group which had poor prognostic factors. The predicted recurrence rate of the postoperative radiation group showed a lower 5-year survival rate than the no postoperative radiation group(P=0.0001). CONCLUSIONS: We conclude that the factors affecting the prognosis were FIGO stage, cell type, depth of invasion, tumor size, and lymph node metastasis, and speculated that the survival rates could be improved by using neoadjuvant chemotherapy for more advanced locally invasive cases properly.

Journal of Korean Neurosurgical Society 2013;53(5):305-308
Myositis ossificans (MO) is a benign condition of non-neoplastic heterotopic bone formation in the muscle or soft tissue. Trauma plays a role in the development of MO, thus, non-traumatic MO is very rare. Although MO may occur anywhere in the body, it is rarely seen in the lumbosacral paravertebral muscle (PVM). Herein, we report a case of non-traumatic MO in the lumbosacral PVM. A 42-year-old man with no history of trauma was referred to our hospital for pain in the low back, left buttock, and left thigh. On physical examination, a slightly tender, hard, and fixed mass was palpated in the left lumbosacral PVM. Computed tomography showed a calcified mass within the left lumbosacral PVM. Magnetic resonance imaging (MRI) showed heterogeneous high signal intensity in T1- and T2-weighted image, and no enhancement of the mass was found in the postcontrast T1-weighted MRI. The lack of typical imaging features required an open biopsy, and MO was confirmed. MO should be considered in the differential diagnosis when the imaging findings show a mass involving PVM. When it is difficult to distinguish MO from soft tissue or bone malignancy by radiology, it is necessary to perform a biopsy to confirm the diagnosis.

The Korean Journal of Laboratory Medicine 2008;28(2):136-143
BACKGROUND: To determine whether nitric oxide (NO) could inhibit activation of platelets stored in a cold or frozen state, we measured platelet P-selectin expression and platelet-bound fibrinogen in platelet-rich plasma (PRP) with S-nitrosoglutathione (GSNO) (Sigma, USA) by flow cytometry. METHODS: PRP was prepared by centrifuging venous blood collected in a 3.2% sodium citrate tube from 10 healthy donors. It was aliquotted into 4 groups (no cryoprotectant, GSNO, GSNO/dimethyl sulfoxide [DMSO] [Sigma], and DMSO), and stored at room, cold and freezing temperatures for 24 hrs. We performed a flow cytometric analysis of all specimens stained with FITC-fibrinogen and PE-CD62P monoclonal antibodies (Becton Dickinson, USA). The results were compared according to the storage temperature and agonist among 4 groups. RESULTS: GSNO inhibited significantly the activation of frozen platelets, but not in the presence of DMSO. GSNO was also shown to preserve the aggregability of frozen platelets because in the presence of GSNO the delta percent change of P-selectin expression and fibrinogen binding of frozen platelets increased significantly irrelevant to DMSO. CONCLUSIONS: GSNO inhibited the activation of frozen platelets and preserved the platelet aggregability; therefore, it may be used as a protectant for platelet cryopreservation.

To present CT and clinical features of active tuberculomas, we analyzed retrospectively CT findings of 14 tuberculomas (n=14) in 13 patients which appeared as solitary pulmonary nodules on plain radiographs and evaluated the response of tuberculomas to antituberculous chemotherapy. Nine tuberculomas (64%) were ovoid in shape and 10 (72%) showed smooth margin. Twelve(86%) tuberculomas were shown as low density lesions on unenhanced or enhanced CT scans. Calcification and cavitation were noted in three (21%) and eight (57%) tuberculomas respectively. Seven (50%) tuberculomas were accompanied by satellite nodules. Acid-fast bacilli (AFB) was positive in all tuberculomas in sputum, lavage fluid, or percutaneous transhoracic needle aspiration (PTNA). Smear and culture of lavage fluid and PTNA aspirate were superior to the detection of AFB than sputum examination. Follow-up study with antituberculous chemotherapy in 14 tuberculomas resulted in complete disappearance in three, decrease in size in seven, and no visible change in the remaining four. These observations suggest that tuberculomas are well-defined, ovoid, and low-density nodules containing calcifications and/or cavitations. Tuberculomas are relatively indolent even with threatment.

BACKGROUND/AIMS: Gabexate, a protease inhibitor, has been known to prevent pancreatic damage following ERCP. We conducted a prospective and randomized study to assess the preventive effect of gabexate. Methods: Of the 96 patients enrolled, 46 were treated with gabexate and 50 with placebo. The groups were similar with regard to sex, age, body-mass index, and the final diagnosis of ERCP. RESULTS: 24 patients (25.0%) had elevated pancreatic-enzyme levels; the frequency was similar in the two groups (P=0.48). Mean serum amylase value at 4 hours after ERCP was similar in patients with elevated basal level (220.5+/-43.2 U/L) and those with normal basal level (170.4+/-31.2 U/L). After the procedures, serum amylase values were lower in the gabexate group (137.1+/-19.8 U/L) than in the placebo group (212.0+/-50.4 U/L). The differences were not significant in the mean levels of amylase between the groups for any of imaging of the pancreatic ducts (pancreatic-duct imaging, 201.5+/-49.4 U/L, bile-duct imaging, 153.7+/-30.0 U/L). But in the patients with pancreatic duct imaging, serum amylase values were significantly higher in the placebo group (295.0+/-97.6 U/L) than in the gabexate group (112.0+/-10.6 U/L)(p<0.05). CONCLUSIONS: Prophylactic treatment with gabexate does not reduce pancreatic damage related to ERCP, but only in the patients with pancreatic duct imaging there were the significant differences between in the gabexate group and in the placebo group.

Although rare, acute subdural hematoma (ASDH) may occur after burr hole trephination (BHT) for chronic subdural hematoma (CSDH). It usually occurs in the hemisphere ipsilateral to the burr hole site and rarely in the hemisphere contralateral to the burr hole site. On computed tomography (CT), SDH is usually crescent-shaped and occasionally lentiform or biconvex, which can be misdiagnosed as epidural hematoma (EDH). In rare cases, ASDH may resolve spontaneously and rapidly. Here, we report a case of rapid spontaneous resolution of contralateral lentiform ASDH after BHT for CSDH in a patient with brain atrophy. A 55-year-old man developed left CSDH 2 months after traumatic brain injury. Left BHT was performed, and a lentiform hematoma, presumed to be EDH, was found in the right frontal region on the CT scan acquired immediately after BHT. On the CT scan acquired 12 hours later, the lentiform hematoma disappeared and spread along the hemisphere. It was presumed to be ASDH. To prevent contralateral ASDH after BHT, slow decompression and minimal gentle or no irrigation should be performed during BHT, particularly in patients with brain atrophy.

BACKGROUND: Cyclosporine has a narrow therapeutic window and many serious side effects. The new oral microemulsion cyclosporine is known to have better absorption profile than non-microemulsion cyclosporine. The purpose of this study was to confirm above finding in stable renal transplant patients and also to compare correlation between AUC0-4 and C0, C2. METHODS: We checked the absorption profile of microemulsion cyclosporine group (N=15, ME group) and non-microeulsion cyclosporine group (N=15, NE group). All Patients had received renal transplantation at least 12 months before. Blood sampling for cyclosporine level was drawn before and at 1, 2, 3 hour after the cyclosporine morning dose (respectively C0, C1, C2 and C3). AUC0-4 was calculated with the formula: 256+C1+0.9xC2+1.4xC3. Age, sex, body weight, serum creatinine and cyclosporine dose were not different between ME group and NE group, but duration after transplantation was significantly higher in NE group (4.7+/-0.8 versus 3.0+/-1.9 year, p<0.05). RESULTS: AUC0-4 in ME group was significantly higher than NE group (2, 816+/-721 versus 2, 055+/-658 ng.h/mL, p<0.05). AUC0-4/dose, Cmax and Cmax/ dose were significantly higher in ME group. But these statistical differences were not consistent in both sexes. The difference of absorption profile between ME and NE group existed only in the female sex. In ME group, C1 correlated best with AUC0-4 (C0: r=0.493, C1: r=0.911, C2: r=0.906, C3: r= 0.789) and in NE group, C2 was the best (C0: r= 0.064, C1: r=0.958, C2: r=0.980, C3: r=0.912). CONCLUSION: Microemulsion cyclosporine is more bioavailable than non-microemulsion cyclosporine in stable renal transplant patients. C2 is better single time point marker for therapeutic drug monitoring in stable renal transplant patients than C0.
