A case of esophagopleural fistula after pleuropneumonectomy is reported. A 59 years old male underwent right pleuropneumonectomy due to tuberculous empyema. The postoperative small esophagopleural fistula was confirmed by esophagogram and was initially managed by a conservative treatment. There was a persistent fistula on follow up esophagogram, therefore we planned the next treatment modality for obstruction of the fistula. For poor general conditions and arrhythmia, an esophageal stent was applied as a non-surgical method. At first, a covered-form stent was inserted, but it migrated to the stomach after 3 months. By using an uncovered-form stent, a complete obstruction of the esophagopleural fistula was achieved.

Partial anomalous pulmonary venous connection is frequently found in any ASD(atrial septal defect) patients. These patients are usually symptomatic, therefore, easily diagnosed as just simple ASD. We experienced a case of a 37-year-old female patient with ASD in which the left upper pulmonary vein was connected to SVC by the left inominate vein. The patient was diagnosed as simple ASD previously. During cardiac catheterization, we found a meaningful oxygen saturation step up between the SVC and its upper portion. Angiogram confirmed PAPVC. The surgical correction of anastomosis of PAPVC with left atrial appendage and direct closure of ASD were done. The patient was discharged 15 days later.

The purpose of this study is to obtain information of simple and effective methods for the pos-tlaminectomy pain control, and to reduce the consumption of supplemental analgesic drugs and side effects. In a double blind study, 75 patients scheduled for lumbar laminectomy were randomly divided into five groups according to the epidurally instilled drugs, such as, morphine 2mg,Group M2; morphine 3mg,Group M3; methylprednisolone 80 mg, Group D; morphine 2mg plus methylprednisolone 80mg, Group M2D; normal saline as a control Group C. All of the drugs were prepared in 2ml normal saline solution. The following items were recorded in the postoperative period: Pain score using visual analogue scale(VAS) at 6, 12, 24, 48 hours after the operation; the episode of supplemental systemic analgesic; the need for postoperative urethral catheterization; any evidence of respiratory depression; pruritus; nausea and vomiting. The results were as follows. I) VAS score were not significantly different between control group and group M2(p>0.05), but usually less in the group M2 and supplemental analgesic consumption was significantly less in the group M2 than in the control group. 2) VAS score were less in the group M3 than in the group M2 and significantly less than in the control group at 6 hour after operation and also supplemental analgesic consumption was significantly less in the group M3. 3) Group D revealed similar VAS score with group M2 at 6 and 12 hour but significantly lower VAS score at 24 and 48 hour after operation than group M2. 4) VAS score were the most significantly less in the group M2D at 6,12,24,48 hour after operation than in the control group and supplemental analgesic consumption was significantly less in the group M2D. 5) Side effects were not significantly different among all groups. These findings suggest that epidurally instilled morphine 3mg, or methylprednisolone 80mg or both before the closure of the laminectomy wound is effective, simple and safe method for the post-laminectomy pain control and reducing supplemental intramuscular analgesics without specific complication.

Spinal fixation using pedicle screws has recently been the focus of increased attention, but the adequate size of pedicle screw and maximum percentage fill as related to the pedicle diameter and are not well known. The objects of this study were to determine the ideal ratio among pedicle, drill and screw diameter, and to determine the maximum percentage fill of the screw without significant decrease of pull-out strength. The materials used for the experiments were 376 thoracic pedicles obtained from the 38 young pigs, and the diameters of pedicles ranged from 3.0 to 8.5mm. After 40% to 100% drilling as compared to pedicle diameter, screws were inserted carefully, and measurements were taken of the outer pedicle changes and pull-out strengths, and adequate drill and screw sizes as related to the diameters of given pedicles were determined. It was found that pull-out strength was the strongest after 60% drill, and the larger the drill diameter, the smaller the holding power, and the larger the screw diameter, the greater the holding power. Maximum pull-out strength was seen at 80-90% fill with 60% drill. After sequentially drilling each pedicle with increasingly larger drill bits, larger screws could be inserted with pedicle changes such as expansion, cutout, split fracture, and comminuted fracture. after larger drilling up to 100%, pedicle screws with diameters smaller than 115% of measured pedicle diameters could be safly inserted without fracture and significant decrease of pull-out strength. It is concluded that effective percentages of drill and screw diameters to the pedicle diameter are 60% and 80-90% respectively, and pedicle screw up to 115% of measured pedicle diameter can be safely inserted into pedicle without significant decrease of pull-out strength. It is thought that fresh pedicle has elasticity and larger screw can be inserted to the pedicle with strong holding after larger drilling.

PURPOSE: The current TNM staging system for papillary thyroid cancer (PTC), which is based on tumor diameter, may not precisely reflect the true tumor burden. Therefore, we investigated whether preoperative tumor volume might more accurately reflect tumor burden and predict prognosis in patients with T1N0 PTC than preoperative tumor diameter. MATERIALS AND METHODS: We retrospectively reviewed data from 1,659 patients with T1N0 PTC, and after exclusion, a total of 1,081 patients were ultimately included. Tumor volume (V) was calculated for all patients using preoperative ultrasonography, and patients were grouped according to tumor diameter (T1a vs. T1b) and tumor volume (V1a vs. V1b). The recurrence-free survival (RFS) rates were then compared for these groups. RESULTS: The mean follow-up time was 66.12±28.75 months, and 97.2% of the cohort experienced RFS. The optimal volume cut-off was defined as 0.545 cm³. There were no differences in RFS rates between T1a/T1b groups (all ages) and V1a/V1b groups (< 45 years of age). However, ≥ 45-year-old patients in the V1b group had a significantly poorer RFS rate than those in the V1a group. These results were confirmed by multivariate analysis. CONCLUSION: Our results indicate that preoperative tumor volume may be more useful for predicting prognosis than tumor diameter in ≥ 45-year-old patients with T1N0 PTC.

Hypertensive intracerebral hemorrhage is one of the most common cause of death in Korea and usually considered as a monophasic event. But recently acute expansion of the hematoma within an hour to a day, has been reported as a cause of severe neurological deterioration and death. To know the incidence and risk factors of acute expansion of the hematoma in hypertensive intracerebral hemorrhage, the authors retrospectively analysed 96 hypertensive intracerebral hemorrhage patients who were admitted to Minjoong hospital from January 1997 to December 1998. Neurological examination with Glasgow Coma Scale and first computed tomography (CT) scan were performed as soon as possible after arrival. Then second CT scan was performed within an hour to a day before the operation. Blood sample was taken within an hour for routine laboratory examination including liver function and coagulation test. The amount and shape of hematoma on CT scans were carefully measured to know whether acute expansion was occurred or not. The patients who have acute expansion of the hematoma were 15 patients (15.6%). Expansion of the hematoma was not correlated with sex, age, site, shape, or amount of hematoma statistically. But thalamic hematoma in location, irregular shape of hematoma, or large amount of hematoma has a tendency of acute expansion. The time of onset to arrival, initial systolic pressure, liver dysfunction and history of heavy alcohol drinking were correlated with acute expansion statistically (p<0.05). The shorter the time of onset to arrival and the higher initial systolic pressure, the more the incidence of acute expansion of the hematoma significantly. Acute expansion of the hematoma was significantly increased with the severity of liver dysfunction and history of heavy alcohol drinking. The levels of glutamic oxaloacetic transaminase (GOT), alkaline phosphatase, gamma-glutamyl transpeptidase (gamma-GTP) and platelet (PLT) count were meaningful indices of hematoma expansion.

PURPOSE: The Gleason score is an important predictor of outcome that is used in conjunction with clinical stage and prostate-specific antigen to guide clinical decision making. The prostate biopsy Gleason grade frequently differs from the radical prostatectomy grade. The aim of this study was to determine the risk factors of Gleason upgrading in patients with low-risk prostate cancer after radical prostatectomy. MATERIALS AND METHODS: We retrospectively analyzed the medical records of 146 patients who underwent radical prostatectomy between 1998 and 2008 in two hospitals of Jeonbuk province in Korea. Pathological Gleason score upgrading was defined as an increase in the Gleason score from < or =6 to > or =7 between the biopsy and radical prostatectomy specimen. Pretreatment clinical and pathological parameters were used to identify predictors of pathological upgrading. RESULTS: Of the total 146 patients, 51 (34.9%) were upgraded postoperatively. Small prostate volume (p=0.008), abnormality on the digital rectal examination, and positive surgical margin (p=0.001) were significantly and positively associated with upgrading after radical prostatectomy. A total of 17 of 65 patients with low-risk prostate cancer (26.2%) were upgraded postoperatively. Small prostate volume (<30 ml) was significantly (p=0.026) and positively associated with upgrading after radical prostatectomy in patients with low-risk prostate cancer. CONCLUSIONS: Overall, 26% of patients with low-risk disease were upgraded postoperatively. Small prostate volume was associated with an increased risk for pathological upgrading after radical prostatectomy. These conclusions should be kept in mind when making treatment decisions for men with low-risk prostate cancer.

Since Wands et al. reported for the first time in 1975 the reactivation of the hepatitis B virus in hematologic disease patients who had been receiving chemotherapy, the efficacy of chemotherapy and immunosuppressants has improved. As a result, the frequency of the reactivation of hepatitis B is increasing. Reported herein is a case of a non-Hodgkin lymphoma patient in her 70s who was suspected to have had HBsAg negative/anti-HBs negative occult HBV infection. The patient experienced fulminant hepatitis caused by the reactivation of hepatitis B, and died three months after the R-CHOP regimen was completed. In the HBsAg negative plus HBV DNA-negative case, there were few instances of viral activation of HBV. In this case, antiviral therapy was needed when the patient was confirmed to have become HBV DNA positive through regular monitoring, but its necessity is often overlooked, unlike the preemptive antiviral treatment in the HBsAg positive cases.
