Authors experienced a rare adenocarcinoma arising in presacral sacrococcygeal teratoma in a adult and herein reported. The patient was a 52 year old female admitted because of lower abdominal pain for 5 to 6 months. Past and familial history were unremarkable. On rectal examination a mass was palpated 3 cm above the anal verge. The large bowel was displaced by an extrinsic mass but there was no evidence of intrinsic tumor lesion on barium enema, CT was done and showed a large presacral tumor attached to the sacrum. Clinical impression was sacrococcygeal teratoma. Resected tumor mass was a relatively well circumscribed cystic mass, measuring 11 x 11 cm and the cystic content was previously evacuated. Inner surface showed ragged appearance, and focal nodular solid area was noted. On microscopic examination, the tumor revealed the derivatives of three germ layers and main components were tissues of respiratory tract. Sections from the solid area showed a well differentiated adenocarcinoma and with stromal, capsular and perineural invasion. Borderline malignant epithelial lesions are also noted suggesting the pathogenesis and progression of this tumor. There was no recurrence for one year after surgery in the follow up.

We present an ultrastructure of an incidentally found renomedullary interstitial tumor also called as medullary fibroma in a 77 year-old female who had a metastatic adenocarcinoma of colon to the ureter. This tumor was a small and grayish white nodule in renal medulla, measuring 0.4 x 0.4 cm. Microscopically the tumor composed of spindle cells, with some vacuolation and intercellular collagen fibers. The electron microscopic observation of the spindle cells reveal that nuclei are spindle to oval shape and cytoplasm contain abundant rough endoplasmic reticulum, polyribosome without microfilaments and cisterna like structures supporting that the renomedullary interstitial cell tumor is renal interstitial cell origin than fibroblasts.

A spinal epidural hemangioma is rare. In this case, a 51 year-old female patient had low back pain and right thigh numbness. She was initially misdiagnosed as having a ruptured disc with possible sequestration of granulation tissue formation due to the limited number of spinal epidural hemangiomas and little-known radiological findings. Because there are no effective diagnostic tools to verify the hemangioma, more effort should be put into preoperative imaging tests to avoid misdiagnosis and poor decisions).

PURPOSE: We studied the result and cilincal significance of transscleral fixation of posterior chamber lens in complete vitrectomized eyes without capsular support. METHODS: We evaluated 30 aphakic eyes of 30 patients and according to the cause of pars plana vitrectomy, there were 9 eyes for intraocular foreign body, 8 eyes for lens dislocation, 8 eyes for retinal detachment, 3 eyes for vitreous hemorrhage, 2 eyes for endophthalmitis. RESULTS: The postoperative best-corrected visual acuity group was intraocular foreign body group and the group of lens dislocation, vitreous hemorrhage, retinal detachment, and endophthalmitis were in the descending order of visual acuity. The most common postoperative early complication was temporary hypotony and the others were hyphema, and temporary increased IOP. The most common postoperative late complication was exposed scleral fixation suture and the others were vitreous hemorrhage, cystoid macular edema, subluxation of intraocular lenses, retinal detachment. CONCLUSIONS: We experienced many postoperative temporary hypotony patients, but all cases were improved in short term period. The complication related to scleral fixation in vitrectomized eyes was imposed to smaller than the scleral fixation in vitreous support. But, in fact the development of retinal detachment or vitreous incarceration complication in the vitrectomized eye was not different from the eyes having vitreous support.

PURPOSE: We studied the result and clinical significance of anterior chamber lens implantation in completely vitrectomized eyes without capsular support. METHODS: We evaluated 15 aphakic eyes of 15 patients. According to the cause of pars plana vitrectomy, there were 6 eyes for lens dislocation, 5 for intraocular foreign body, and 4 for rhegmatogenous retinal detachment. RESULTS: The final available postoperative best-corrected visual acuity was 0.5 or better in 9 eyes (60%). No statistically significant difference was noted in preoperative and postoperative IOP. The average of postoperative astigmatism was 1.14 +/- 0.79D. The most common early complication was temporary increase in IOP, but we could control IOP within normal limit with transient treatment. The postoperative late complications were glaucoma, IOL decentration and cystoid macular edema, but serious postoperative complications such as bullous keratopathy and retinal detachment were not found. CONCLUSIONS: The anterior chamber IOL implantation appears to be well tolerated and represents a simple alternative to transscleral fixation of a posterior chamber IOL in completely vitrectomized aphakic eyes.

BACKGROUND: Cell cycle deregulation plays a major role in chemical multistage carcinogenesis.Therefore, the evaluation of cell cycle proteins is important. METHODS: In order to induce carcinogenesis in the rat urinary bladder, 0.05% N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN)was administered to male Sprague-Dawley rats for 30 weeks. Expressions of cyclin D1, A, E, and B1 were examined by immunohistochemical stainings. RESULTS: Urothelial cell hyperplasia appeared at 5 weeks, followed by papilloma at 10 weeks. Superficial carcinoma was observed at 20 weeks, and invasive carcinoma developed in 40% (4/10) of the rats at 30 weeks. Expressions of cyclin D1 and A increased sequentially from normal mucosa throughhyperplasia, papilloma, and carcinoma (p<0.01). Expressions of cyclin D1, B1 and cyclin Ewere higher in invasive carcinomas than in superficial carcinomas (p<0.01). In contrast, therewas no significant difference in the expression of cyclin B1 between hyperplasia, papillomaand superficial carcinoma. CONCLUSIONS: The present results indicate the important roles of cyclin D1 and A in the development of BBN-induced urothelial carcinoma of rats. Aberrantexpression of cyclin B1 and E may contribute to the progression from superficial to invasivebladder cancer rather than tumorigenesis.

Cumulative trauma disorders were surveyed in a cross-sectional study of 100 male ship yard workers and 43 male office workers. And baseline checklist for risk assessment of cumulative trauma disorders was applicated in a ship making process. Cases of cumulative trauma disorders were defined using physical examinations and electronic diagnostic methods. Data on demographics, individual factors (medical condition), work organization and psychosocial aspects of work were obtained by questionnaire. Association between the above factors and cumulative trauma disorders were assessed by multiple logistic regression models. 29(29 %) participants of male shipyard workers and 4(9.2 %) study subjects of male office workers met our case definitions for cumulative trauma disorders. The myofascial pain syndrome of neck muscles(12 % of participants) and carpal tunnel syndrome(5 % of participants) were the major two medical conditions in shipyard workers. The odds of male shipyard workers for cumulative trauma disorders to male office workers was 3.15 after adjustment of age(95 % C.I. :2.25-5.44). And the variables such as duration of present job, HIVD condition, and surges in workload were associated at least one of the cumulative trauma disorders in the final models (p<0.05) . This study indicates that work related upper extremity musculoskeletal disorders are relatively common among shipyard workers, and shows that the psychosocial factors is not likely to be related to the occur rences of these disorders in heavy workers. Also we developed baseline checklist for risk assessment of cumulative trauma disorders. The checklist was unique in that its expected users were industrial hygienists and occupational healthing nurses who did not have much ergonomic background and in that it was targeted to Korean workers in various types. As the first application of the checklist, shipyard workers were evaluated.
