Mutation in the p53 suppressor gene is the most common genetic alteration found in human cancers including primary brain tumors. Ki-67 labeling index(LI) is known to be a marker of proliferating activity. The purpose of this study was to verify whether an immunohistochemical expression of p53 antibody and Ki-67 LI could be related to different clinicopathologic parameters including histologic grade, size, invasiveness and recurrence of the brain tumors. Materials were based on the 147 surgically resected brain tumors during the last two years. Of the 147 brain tumors, there were 35 astrocytic tumors, 35 meningiomas, 10 oligodendrogliomas, 7 craniopharyngiomas, 5 dysembryoplastic neuroepithelial tumors, 4 medulloblastomas, 5 ependymomas, 23 pituitary adenomas, 9 schwannomas, and 14 other brain tumors. The p53 expression and Ki-67 LI were higher in malignant brain tumors including astrocytic tumors, medulloblastoma, PNET and gliosarcoma. The p53 positivity was correlated with histologic grades and tumor recurrence. The brain tumors with a high Ki-67 LI(>6%) also showed a close relationship to a higher histologic grading, radiological invasiveness and recurrence. There was no evident correlation with the age and tumor size with p53 expression and Ki-67 LI. These results suggest that p53 overexpression and high proliferation potential of the tumor cells are associated with the higher histologic grade and aggressive clinical course in the central nervous system tumors.

The measurement of intraocular pressure (IOP) is influenced by the parameters of corneal thickness, corneal curvature, and corneal astigmatism. LASIK changes these parameters and may influence measurements of IOP. IOPs of 62 eyes were analysed before LASIK and 6 months after LASIK and the correlation coefficient between IOP and corneal thickness & corneal curvature was determined. Preoperative and postoperative IOP after 6months follow-up was 13.03 +/- 3.26 mmHg, 9.26 +/-1.69 mmHg respectively. Postoperative IOP was significantly decreased as compared to preoperative one. There was a tendency that showed the low IOP was related to the decrease of corneal thickness & corneal curvature. Each correlation coefficient was r=0.563, r=0.646 respectively but the coefficient`s influence was not determinable. The decrease of corneal thickness and curvature showed a constant relation to the lowered IOP, therefore it should be taken in account in the patient evaluation.

Canaliculitis is an uncommon condition. It is often difficult to diagnose because of its chronicity and its multitude of clinical presentations. We reviewed the nature, the diagnosis and therapy of six patients of chronic lacrimal canaliculitis. Bacteriologic investigation showed one case of E. coli, one case of alpha-hemolytic streptococcus, two of coagulase-negative staphylococcus and no growth to be seen in two cases. On dacryocystography, canalicular diverticulum were found in three cases. Five patients were treated with conservation therapy and one case improved with surgical treatment. Canaliculitis can be diagnosed by clinical features and dacryocystography. Conservative therapy should take priority to surgical treatment.

Lower lid retraction can be caused by many etiologies but few require surgical intervention except for cosmetic reasons and exposure deratitis due to lagophthalmos. We report three lower lid retraction patients who underwent lower lid reconstruction was due to congenital etiology or was secondary to excessive inferior rectus muscle recession or lower lid blepharoplasty due to orbital neurofibroma. All three patients found their results satisfactory and showed no severe side effects during the follow-up period. It is suggested that the use of scleral spacer combined with lateral canthoplasty be an effective surgical procedure for correction of lower lid retraction.

We report two cases of angiokeratoma circumcriptum. One of them was 20 year- old male, who had multiple dark erythematous 0.5 cm to 2 cm sized keratotic papules and nodules surrounding irregular shaped erythema scattered or grouped on the right lower leg. The other case was 36 year-old male, who had Q. 7 cm sized dark erythematous papules and 2 cm sized dark brown colored nodule with central ulceration on the medial part of the left upper thigh, The two patients had skin lesions at birth. Histopathologic finding disclosed markedly dilated vessels containing many red blood cells mainly in the papillary dermis, which in some, were surrounded by elongated rete ridge. Cavernous hemangioma like lesion was present in the lower dermis and subcutaneous fat in case 2.

PURPOSE: To report the clinical data and visual outcomes after treatment of patients with dysthyroid optic neuropathy (DON). METHODS: We retrospectively reviewed the medical records and orbital images of 40 patients (65 eyes) with DON and analyzed the visual outcomes after treatment with intravenous steroids pulse therapy, radiotherapy and orbital decompression. RESULTS: The study included 21 men and 19 women, with 10 (25%) being diabetic patients. Visual field test results revealed defects in 88.7% of DON eyes; afferent pupillary defects in 63.2%; reduced color vision in 78.5%; and abnormal visual evoked potentials in 84%. Orbital imaging showed moderate to severe apical crowding in 95% of the orbits and intracranial fat prolapse in 24.2%. Median best corrected visual acuity improved from 0.4 to 1.0 after one year of treatment (p < 0.001). We noted more improvement in vision with the use of decompressive surgery than with non-surgical methods (p < 0.05). Recurrences occurred in 7 patients who had not received orbital radiotherapy. CONCLUSIONS: Visual field defects and apical crowding seen on orbital imaging were the most sensitive indicators for the detection of DON. Treatment with intravenous steroids pulse therapy, radiotherapy and orbital decompression effectively improved visual outcomes in cases of DON.

p27kip1, a cyclin dependent kinase inhibitor, has been recognized as a negative regulator of cell cycle. To investigate the role of p27kip1 on progression of cancer and apoptotic pathway, we analyzed p27kip1 expression using immunohistochemical stain in 40 cases of prostatic adenocarcinoma and apoptotic index by TUNEL method in 30 cases of prostatic adenocarinoma. Both were correlated with Gleason grade and Gleason score. Loss of p27kip1 expression was more frequent in prostatic adenocarcinomas of higher score (Gleason score 7 to 10) (60.7%) than in those of lower score (Gleason score 4 to 6) (33.3%) (p<0.05). The value of mean apoptotic index of carcinoma was 1.13+/-0.26, 1.80+/-0.91, 2.06+/-0.79, and 2.12+/-0.82 in grade 2, 3, 4, and 5, respectively, and was positively correlated with grade of carcinoma (p<0.05). Mean apoptotic index of higher Gleason score (score 7 to 10; 2.05+/-0.63) was also significantly increased than in lower Gleason score (score 4 to 6; 1.34+/-0.39) (p<0.05). Mean apoptotic index in cases with and without p27kip1 expression was 1.92+/-0.86 and 1.89+/-0.81, respectively (p>0.05). These results suggest that loss of p27kip1 expression and increased apoptotic index may be the morphologic markers to predict the behavior of prostatic adenocaricnoma. The role of p27kip1 on apoptotic pathway seems to be meager in this study and needs further study.

I think endoscopic retrograde cholangiopancreatography (ERCP) is a very highly advanced upper endoscopic procedure, and is an uncomfortable procedure that requires adequate sedation for its successful conduction. But, The optimum method for sedation for endoscopic procedures is not known. Propofol has a faster recovery time than traditional sedative agents, but may be associated with increased complication rates. Dexmedetomidine is a highly selective alpha2 adrenoceptor agonist that has many advantages over other sedatives. In addition to producing sedative, analgesic, and anxiolytic effects, it provides respiratory stability. When patients are treated with appropriate analgesics, sedation with dexmedetomidine for ERCP would be safe and associated with better outcomes than sedation with other sedatives.

In attempting to ellucidate the mechanism of action of CCl4 toxicity on the liver, the histobgical and histochemical studies were carried out, at the cellular or ultrastructural level, rats were given a single oral dose of 1.25 ml/kg of CCl4 one hour after cervical spinal cordotomy. Hepatic lesions induced by CCl4 administration such as the fatty change of hepatic cells and the sinusoidal congestion were abolished by cordotomy. The decreased activities of adenosine triphosphatase and alkaline phosphatase in the hepatic cells and bile canaliculi of the poisoned animals were restored to a large extent by the operation. Cordotomy also prevented some liver cell changes as seen by the electron microscope in the CCl4-intoxicated rats. It is evident that the hepatotoxic effects of carbon tetrachloride can be inhibited or prevented by cervical cordotomy.
