Optic nerve evulsion is a devastating, uncommon cause of sudden visual loss following major head trauma. Less frequently, it is associated with pointed non penetrating orbital injuries with minimal ocular trauma. Possible mechanisms of injury include extreme rotation and forward displacement of the globe, penetrating orbital injury causing a backward, pull on the optic nerve, and sudden increase in intraocular pressure causing rupture of the lamina cribrosa. Funduscopic examination may reveal total or partial lack of the optic disc and variable degrees of intraocular hemorrhage. Fluorescein angiographic finding is variable, visually evoked potential often shows the delay in latency or the decrese in amplitude, Computed tomography or magnetic resonance imaging usually demonstrates an intact optic nerve sheath. We report a case of optic nerve evulsion which diagnosed by retinoscopic finding, fluorescein angiography, computed tomography, and clinical history. We present it with a review of the literature.

BACKGROUND: The bcl-2 is a newly known oncogene involved in tumorigenisis by blocking apoptosis or programmed cell death. Overexpression of bcl-2 protein has been detected in a variety of human malignancies. However, recent studies of the expression of bcl-2 protein in human melanoma and melanocytic nevus have been controversial. OBJECTIVE: The purpose of this study was to examine whether there are any differences in the expression of bcl-2 protein between melanocytic nevus and rnalignant melanoma. METHODS: Immunohistochemical analysis of bcl-2 protein expression was performed on the formalin-fixed, paraffin-embedded tissue sections of 22 melanocytic nevus and 29 malignant melanomas (20 primary and 9 metastatic) using anti bcl-2 monoclonal antibody with an avidin-biotin peroxidase complex procedure. RESULTS: The results were as follows. 1. The positive rate for bcl-2 protein was observed in 95.4% (21/22) of melanocytic nevus and 95.0% (19/20) of primary malignant melanomas. Therefore, there was no significant difference between the two groups in the positive rate for bcl-2 prtoein. 2. The percentage of stained cells and the staining intensity of bcl-2 protein were significantly increased in melanocytic nevus compared to malignant melanoma (p<0.05). 3. The positive rate for bcl-2 expression of metastatic malignant melanoma [44.4% (4/9)] was significantly decreased compared to that of primary malignant melanoma [95.0%(19/20) ] (p<0. 05). But, there was no significant difference betweeen tumor thickness and histological type of malignant, melanoma in the expression of bcl-2 protein. 4. In melanocytic nevus, immunoreactivity of bcl-2 protein gradually diminished or even disappeared towards the deep dermis. CONCLUSION: the bcl-2 expression was decreased in malignant melanoma compared to melanocytic nevus. It. suggests that the loss of bcl-2 expression may play a significant role in the progression and metastasis of malignant melanoma.

PURPOSE: To evaluate the safety and efficacy of repeat trabeculectomy with mitomycin C (MMC) in the management of previous failed trabeculectomy patients. METHODS: We retrospectively reviewed the medical records of 44 eyes of 41 glaucoma patients who had been followed up for at least 6 months after repeat trabeculectomy with MMC and analyzed the success rates according to clinical factors, cumulative success rates, risk factors for surgical failure and complications. Surgical success was defined as an intraocular pressure (IOP) of 21 mmHg or less regardless of glaucoma medications and loss of vision. RESULTS: Postoperative success was obtained in 34 (77.3%) out of 44 eyes after a mean follow-up period of 38.7 months. From Kaplan-Meier survival analysis, cumulative success rates after 6, 12, 24, and 36 months were 97.7%, 89.6%, 83.5%, and 80.1%, respectively. Success rates were significantly lower in eyes with preoperative IOP of 30 mmHg or more. Postoperative complications included transient hypotony in 7 eyes, choroidal detachment in 4, hyphema in 4, and cataract progression in 4. CONCLUSIONS: The success rates of repeat trabeculectomy may be lower than of primary trabeculectomy. However, considering the relatively high success rates and low complications of repeat trabeculectomy with MMC compared to the reported results of glaucoma drainage device implantation, repeat trabeculectomy with MMC is an effective and relatively safe surgical option as the secondary surgical procedure for previously failed trabeculectomy patients.

The pseudolymphoma syndrome that may mimic malignant lymphoma clinically and histopathologically has been described as a hypersensitivity reaction to anticonvulsant drugs. It consists of the triad of a fever, generalized rash and lyrnphadenopathy. In some cases, varying degrees of malaise, hepatosplenornegaly, abnormal liver function tests, arthralgias, eosinophilia and blood dyscriasias may also be present. We report a case of pseudolymphoma syndrome due to carbamazepine in a 47-year-old man. He had a diffuse edematous and erythematous patches, papules and vesicles associated with high fever, hepatosplenomegaly and lymphadenopathy. The histopathologic finding slowed a dense atypical mononuclear cell infiltrate of the upper dermis associated with Pautriers microabscess like structures and severe dermal edema. Laboratory findings revealed leukocytosis and an abnormal liver function test. Three weeks after the withdrawal of carbamazepine and treatment with oral prednisolone, his skin lesion and general condition markedly improved.

We described 2 patients with Marchiafava-Bignami disease, a neurological disorder associated with chronic alcohol consumption. Patient 1 expressed general weakness and confusion, while patient 2 expressed dysphagia and seizures. Lesions involving the corpus callosum were identified with T2 weighted MR imaging in which there was a hyperintensity in the splenium of patient 1 and in the entire corpus callosum of patient 2. While the conditions of both patients were improved by with nutritional support, they were left with cognitive impairment.

The paratertiary butylphenol formaldehyde resin(PTBP-FR) is commonly used in neoprene shoe adhesive to provide stability, durability, flexibility, and to stick quickly. We report here a case of allergic contact dermatitis in a 22-year-old female, who had well defined, pruritic, erythematous, and papulovesicular lesions on the lateral side of the left foot and ankle for 3 years. Patch test showed 2+(vesicular) reaction .to PTBP-FR(1% in petrolatum), a piece of leather shoes(as is), and a piece of leather watch strap(as is).
