Many carcinomas have an active mononuclear cell infiltrates surrounding tumor. Various in vitro assays have shown that cellular constituents of peripheral blood mononuclear cells(PBMC) can alter growth of carcinoma cell line. Author compared the effects of normal fibroblasts on squamous cell carcinoma cell line(SCL-1) along with those of sctivated and/or nonactivated PBMC on SCI 1 using a skin equivalent system. This system prevents direct cellular contact by growing SCL-1 on an overlying Millicell-HA membrane and normal fibroblast or supernatants of PBMC in a lower chamber. Normal fibroblasts enhanced the outgrowth of SCL-1 and induced a more organized phenotype of SCL-1. Supernatants from nonstimulated PBMC suppressed outgrowth of SCL 1, and concanavalin A stimulated PBMC supernatants alterd rnorphology of cultured SCL-1 from a disorganized phenotype to a more organized phenotype. It is concluded that fibroblasts and PBMC may affect the growth and differentiation of SCL-1 via their mediators(cytokines)

Forytfour-year-old female inpatient, who was gravely ill, developed vesicobullae on the greenish patches surrounded by narrow red to brown halo in the left lower extremity. Two years ago, she had treated by surgical operation and radiation therapy for cervix cancer. Blood and bullous fluid cultures showed Pseudomonas aeruginosa. She developed gangrenous and mummificated skin lesions after septic shock therapy but died due to disseminated intravascular coagulation.

One hundred patients of osmidrosis were treated by surgical procedure at the Department of Dermatology, Wonkwang University Hospital. The methods of operative treatment were elliptical excision for 37(74), bipedicle incision with apocrine glancl undercutting for 14(28), and single incision wit.h apocrine gland undercutt,ing for 49 (98). The results were summarized as follows : 1. Of the 74 axillae treated by elliptical excision, one occurred recurrence, and 1.7 showed complication, hematoma in 6, infection and delayed union in 4, each necrosis and severe scar in one each, 2. Of the 28 axillae treated by bipedicle incision with apocrine gland undercutting, 6 showed complication; hematoma in 4, infection and delayed union in one each 3. Of t..he 98 axillae treated by single incision with apocrine gland undercutting, 5 showed complication, hematoma in 3, infection and delayed union in one each In conclusion, single incision with apocrine gland undercutting was found to be more excellent compared with the other surgical methods.

We herein report three cases of pararneatal urethral cyst, which developed on the male urethral meatus. These cysts occurred since birth or childhood, and did not interfere with urinary of sexual function. Histologically, these cysts were lined by pseudostratified columnar epithelium with variable thickness. No recurrence was evident after simple excision.

Predisposing factors for venous thrombosis can be identified in the majority of patients with established venous thromboembolism (VTE). However, an obvious precipitant may not be identified during the initial evaluation of such patients. In the present case, a 47-year-old female presented to the emergency department of our hospital after ingesting multiple drugs. She had no VTE-related risk factors or previous episodes, nor any family history of VTE. After admission to the intensive care unit sudden hypoxemia developed, and during the evaluation cerebral, renal, and splenic infarctions with pulmonary embolisms were diagnosed. However, the sources of the emboli could not be identified by transthoracic echocardiography or computed tomography angiography. Protein C deficiency was identified several days later. We recommend that hypercoagulable states be taken into consideration, especially when unexplained thromboembolic events develop in multiple or unusual venous sites.

In 1947, Liver described adenoid squamous cell carcinoma under the title of "adenoacanthoma of sweat gland". This tumor is not rare, but reported cases in literatures were relatively few. The tumor were frequently found in the sun-exposed skin; such as face, ear, neck etc.. The cases involving non-sun-exposed area, such as oral and labial mucosa, nosopharynx and vulva etc., were also reported. Therefore, the relation between the pathogenesis of adenoid squamous cell carcinoma and sun damage has been still debated. Immunohistochemical studies have recently suggested that this tumor is squamous cell carcinoma undergoing acantholysis. The authors experienced a case of adenoid squamous cell carcinoma of the vulva in a seventy-one year old female patient. She had suffered from itching sensation on vulva for 10 years, and palpable mass on vulva for 1 month. On gross examination, a pale gray pigmentation and erosion, was noted at the right labia major, the minor extending left labia major and minor. On microscopic examination, nests of atypical epithelial cells extending into the cornium showed an adenoid architecture. These were composed of a peripheral layers of cuboidal cell in a lacy pattern. And the glandular spaces contained dyskeratotic acantholytic tumor cells in central portion. Therefore we diagnosed this case as adenoid squamous cell carcinoma of the vulva.

PURPOSE: With the development of bipolar device, which complement the weak points of conventional monopolar device, TURP became more appliable in large volume prostate. We evaluated the possibility and effectivity of bipolar TURP in large volume prostate by analysing treatment results. MATERIALS AND METHODS: Total 78 male patients who received bipolar TURP in our center between April 2004 and December 2006, were divided into two groups based on prostate volume (>75g = large volume prostate group, <75g = control group). We compared each of age, prostate volume, resection volume, operation time, IPSS, Qmax, change of serum Na+ & hemoglobin, and perioperative complications. RESULTS: There was no statistical difference between preoperative IPSS and postoperative IPSS between the both groups. In preoperative status, Qmax was statistically higher in small volumed prostate group. But, after bipolar TURP, Qmax of each group were significantly improved, and statistical difference between the two groups were disappeared. Patient age, prostate volume, resection weight, hemoglobin down, hospitalization day, catheterized duration were statistically higher in the large volume prostate group. But, in the clinical aspect, these differences were acceptable. Immediate postoperative hematuria and hypothermia were more frequent in large volume prostate group. Long term complication rates were almost the same in two groups, and there was no TUR syndrome in both groups. CONCLUSION: Transurethral resection of large volume prostate (>75g) using bipolar device is as effective as of general (<75g) prostate hyperplasia. Bipolar TURP can be another therapeutic option of large volume prostate, which in the past indicated open prostatectomy, to escape from higher surgical morbidity.

Several evidences suggested that Toll-like receptor 9 (TLR9) plays an important role in atherosclerosis and neuroprotection but the association between the TLR9 and risk for stroke or outcomes after stroke has not been investigated. The aim of the present study was to investigate the association between TLR9 polymorphisms and the risk for ischemic stroke using a case-control study design. We also explored the correlation between the polymorphisms and outcomes after stroke. We enrolled consecutive Korean stroke patients and controls without history of stroke. Four polymorphisms, namely c.-1486T>C, c.-1237C>T, c.1174A>G, and c.2848G>A were examined using polymerase chain reaction followed by direct sequencing. Initially we examined 193 stroke patients and the same number of healthy adults who had no history of stroke as controls. Due to deviation from Hardy-Weinberg equilibrium of initial controls, we performed genetic analysis of two polymorphisms (c.1174A>G and c.2848G>A) for additional 165 controls. The genotype frequency of four polymorphisms did not differ significantly between stroke patients and controls in unadjusted analysis. The variant allele (C) in c.-1486 locus was associated with significantly increased chance of favorable functional outcome at three month after stroke (OR 2.32, 95% CI 1.02~5.26, p = 0.043).
