The diagnosis of carcinoma in situ of urinary bladder is difficult in that the symptoms and cystoscopic findings are nonspecific. The cytology of urine could be helpful for diagnosis of carcinoma in situ of urinary bladder. We present a case of bladder washing cytology of carcinoma in situ. A 54-year-old man presented with dysuria for 1 year. Cystoscopic findings revealed multifocal reddish trabeculated lesions. The bladder washing cytology revealed rather uniform tumor cells which were singly scattered or forming syncytium in the clean background. The nuclei were round to oval with inconspicious nucleoli. The cystoscopic biopsy revealed typical histologic features of carcinoma in situ of urinary bladder.

Fine needle aspiration of the breast is an important diagnostic tool in malignant lesions, but is also useful in differentiation of inflammatory breast diseases mimicking carcinoma clinically and radiologically. Recently, the authors have experienced eight biopsy-proven cases of chronic inflammatory diseases of the breast, which consisted of 4 cases of duct ectasia, 2 cases of fat necrosis, and a case of tuberculous mastitis and granulomatous mastitis respectively, Their cytoiogic features mainly based on the components and the relative frequency of inflammatory cells were evaluated for differential diagnosis of chronic inflammatory breast diseases. The results are as follows ; 1. In cases of duct ectasia, varying amount of neutrophils, mononuclear leukocytes, histiocytes and multinucleated giant cells were intermixed with benign epithelial cell clusters. 2, Abundant fat tissue fragments were diagnostic for fat necrosis. Histiocytes and mononuclear cells were main components but not rich, and neutrophils and giant cells were infrequently observed. 3. Characteristic granulomas composed of epithelioid cells, mononuclear leukocytes and Langhans' type giant cells and lymphocytic infiltrates were conspicuous in tuberculous mastitis, and occasionally neutrophils, necrotic materials and epithelial cell clusters were found. 4. In granulomatous mastitis, epithelioid cell granulomas were also noted but numerous neutrophils and histiocytes were intermingled within or outside the granulomas.

In a six-year period(1988. 5-1994. 4), fine needle aspiration cytology(FNAC) of 322 pulmonary lesions from 296 patients were performed at Soonchunhyang University Hospital. Of these 322, malignancy was diagnosed cytologically in 139(43.2%), suspicious malignancy in 7(2.2%), negative in 164(50.8%), and insufficient material in 12(3.8%). Malignant lesions consisted of 54 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 18 cases of small cell carcinoma. They were verified by histologic examination in 70 cases. There were 2(0.6%) false positive cases due to florid bronchoalveolar hyperplasia and atypical bronchial epithelial cells associated with granulomatous lesion. The overall accuracy rate was 90%, the sensitivity 84.3% and the specificity 94.7%.

Metastatic tumors occur more frequently in the liver than in any other organ, Guided percutaneous fine-needle aspiration (FNA) of the liver is often recommended for confirmative diagnosis of the metastatic lesion, because of its simplicity, high yield, and reasonable safety. The authors studied retrospectively cytologic findings of 110 cases of metastatic tumors to the liver. The frequent primary sites were the stomach (23 cases), pancreas (19 cases), gallbladder (12 cases), and periampullary lesions (6 cases). Most of the metastases were carcinoma (106 cases). There were only 4 cases of sarcoma. The characteristic cytologic findings of FNA of meatastatic tumors were dirty background, abrupt change between hepatocytes and malignant cells, and desmoplasia. Some tumors displayed rather distinctive cytologic appearance that suggests primary sites. For example, the colonic adenocarcinoma showed tall columnar cells with a palisading arrangement, adenocarcinoma of gallbaldder showed focal squamous differentiation in some cases, and metastatic renal cell carcinoma and neuroblastoma showed also distinctive cytologic findings. Because the cytologic features of metastatic tumor are very similar to those of primary tumor, correct cytologic typing may be helpful in pursuit of an occult primary site of metastatic liver lesions, reducing extensive diagnostic investigation in poor prognostic patients.

BACKGROUND: Many Studies regarding hemodynamic changes by various vasodilators, such as nitroprusside, nifedipine, and hydralazine have been reported, however little data are available upon acute hemodynamic change due to captopril, an angiotensin converting enzyme inhibitor especially in chronic regurgitant valvular heart disease. Therefore the aim of this study is to evaluate the acute hemodynamic effects of sublingual captopril in patients with regurgitant valvular heart diseases. METHODS: Among the 9 patients enrolled in this study, 5 patients mitral regurgitation, 2 had aortic regurgitation, and 2 had both. Five had patients were male and 4 were female. Before, 15 minutes and 30 minutes after administration of 25mg of captopril via sublingual route, forward cardiac output was measured three times using Swan-Ganz catheter. Right and left cardiac catheterization were also done at each phase and measurement of pulmonary capillary wedge pressures, pulmonary artery pressures, right atrial pressures, aortic pressures, left ventricular pressures were done. RESULTS: 1) Heart rate, pulmonary capillary wedge pressures, cardiac output and cardiac indices left ventricular end-diastolic pressure, diastolic and mean aortic pressures, and diastolic pulmonary artery pressure showed no significant change after administration of sublingual captopril. 2) Systolic aortic pressure decreased significantly from basal value(130+/-35) to 15 minute value(126+/-39). 3) Systemic vascular resistance at 15 minute showed significant reduction as compared with basal value(from 1743+/-551 to 1642+/-491). Pulmonary vascular resistance at 30 minutes(254+/-193) was significantly lower than basal value(282+/-229). CONCLUSIONS: Reductions of systemic and pulmonary vascular resistance occurred relatively rapidly, however, acute effects on cardiac output and pulmonary capillary wedge pressures were not evident. Clinical implication of sublingual captopril in patients with regurgitant valvular heart diseases is worth evaluationg by more extensive hemodynamic studies.

PURPOSE: Simple closure, regardless of using an omental patch, continues to be the preferred option for many surgeons. It is a easy, quick and safe operation, and it can be applied to all situations by every surgeon. The purpose of this study was to investigate the feasibility of routinely using laparoscopic repair for treating perforated peptic ulcer. METHODS: A retrospective review was carried out on 68 consecutive patients who underwent patch repair for a perforated peptic ulcer; 11 underwent laparoscopic repair and 57 underwent open repair. Laparoscopic repair was performed by one surgeon at the same hospital between March, 2006 and February, 2009. Both groups were compared according to the Mann-Whitney U-test. A p value <0.05 was considered to be significant. RESULTS: Statistical significance (p<0.05) between two groups (laparoscopic vs. open) was present regarding to the postoperative morbidity (0 vs. 16 cases, respectively), the hospital stay (4.8 vs. 12.7 days, respectively), the postoperative day of resuming an oral diet (3 vs. 5.7 days, respectively). The mean operative time of laparoscopic repair (78 minutes) was shorter than that of open repair (82 minutes) but this was not statistically significant (p=0.81). We excluded using a pain scale or assessing the use of analgesics in this study because of the popularity of IV PCA (intravenous patient-controlled analgesia). CONCLUSION: Laparoscopic primary repair is a safe emergency procedure for treating perforated peptic ulcer patients.

PURPOSE: Leber's hereditary optic neuropathy (LHON) is caused by point mutations in mitochondrial DNA. The authors report a case of a middle-aged man with genetically confirmed LHON, combined with bilateral normal tension glaucoma (NTG). CASE SUMMARY: A 48-year-old man presented with complaints of decreased visual acuity in his left eye. His corrected visual acuity was 20/16 in the right eye and 20/63 in the left eye. The fundus photographs revealed a bilateral, superotemporal and inferotemporal retinal nerve fiber layer defect, corresponding to his visual field defect. The patient was diagnosed with bilateral NTG. After 2 months, the patient's corrected visual acuity in the left eye worsened to counting fingers and a central visual field defect was noticed in the Humphrey visual field test in the left eye. At 4 months after the initial visit, his corrected visual acuity in the right eye became 20/100, and the Goldmann visual field test demonstrated cecocentral scotoma. The fundus photographs showed a papillomacular bundle defect in his left eye. At 7 months after the initial visit, his visual acuity was hand movement in the right eye and a finger count in the left eye. A series of LHON gene mutation tests revealed a 11778 mitochondrial gene mutation, and the patient was diagnosed with LHON. CONCLUSIONS: Proper diagnosis of LHON might be disturbed by atypical manifestation of other optic nerve diseases, such as glaucoma. Therefore, suspecting LHON and checking for gene mutations as part of the work-up in patients with bilateral optic neuropathy is critical.

PURPOSE: To evaluate the results of the treatment of intercondylar fractures of the humerus using Y-plate. MATERIALS AND METHODS: The subjects were 17 patients with intercondylar fracture of humerus who were treated using the Y-plate. Nine cases were C1 type, 4 were C2 type, and the remaining 4 were C3 type. 11 subjects had accompanying fractures of another part of the body. The average age was 48.8. The average follow up period was 33 months. We used Mayo Elbow Performance Score and Risborough-Radin's rating score for each patient as the methods of rating. RESULTS: The average range of motion of the elbow was 105 degrees (50~150 degrees). According to Cassebaum's classification for elbow range of motion, 7 cases were rated very good, 1 cases were good, 4 cases were fair, and 1 cases were poor. According to Mayo Elbow Performance Score, 7 were excellent, 7 were good, 2 fair, and 1 poor. Of the 3 patients who were fair or poor in Mayo Elbow Performance Score, 2 were type C3 fractures, and all 3 had major accompanying fractures. No significant postoperative complications developed in all cases. CONCLUSION: The fixation with Y-plate can still be a relatively good modality of treatment for interconylar fractures of the humerus in selected cases, in spite of the known mechanical weakness of the Y-plate. The patients with severe intra-articular comminution showed relatively poor results. And we think that the age of the patient and the energy of the injury have more or less influence on the results of treatment.

PURPOSE: To evaluate marginal leakage of bulk fill flowable composite resin filling with different curing time by using microcomputed tomography technology. MATERIALS AND METHODS: 30 previously extracted human molars were randomly divided into 6 groups based upon restorative system and different curing time. Class II cavities (vertical slot cavities) were prepared. An individual metallic matrix was used to build up the proximal wall. The SonicFill or SureFil SDR flow was inserted into the preparation by using 1 bulk increment, followed by light polymerization for different curing times. The different exposure times were 20, 40, and 60 seconds. All specimens were submitted to 5,000 thermal cycles for artificial aging. Micro-CT scanning was performed by using SkyScan 1272. One evaluator assessed microleakage of silver nitrated solution at the resin-dentin interface. The 3D image of each leakage around the restoration was reconstructed with CT-Analyser V.1.14.4. The leakage was analyzed with the Mann-Whitney test. RESULTS: Significant differences were observed between the light curing times, but no significant differences were found between the bulk fill composite resins. Increasing in the photoactivation time resulted in greater microleakage in all the experimental groups. Those subjected to 60 seconds of light curing showed higher microleakage means than those exposed for 20 seconds and 40 seconds. CONCLUSION: Increasing the photoactivation time is factor that may increase marginal microlekage of the bulk fill composite resins. Further, micro-CT can nondestructively detect leakage around the resin composite restoration in three dimensions.
