Glutaraldehyde is commonly used as a biocide to disinfect delicate instruments such as dental instruments, to treat warts, hyperhidrosis and bullous diseases and as a preservative in various materials. Contact sensitivity to glutaraldehyde may not be detected, because it is not included in the standard screening chemicals recommended in the screening tests. We report a case of allergic contact dermatitis caused by Wydex(2% glutaraldehyde). A 54-year-old female made a visit to our departrnent with eczematous dermatitis of both hands, neck and face. She worked as a cleaner in delivery room and newborn nursery, and had developed the dermatitis 1 month after Wydex' containing 2% glutaraldehyde had been to clean the rooms. She had no family or personal history of atopy or contact dermatitis. Patch tests with Korean Standard(KS-1000) and Wydex were performed, and patch tests with 2% glutaraldehyde, 0.2% gluteraldehyde and rubber mix followed. The positive results were, Wydex 2% ++, 0.2% +, 0.02% + and. glutaraldehyde 2% aq. +, 0.2% aq. + on day 2 and day 4. We confirmed that the skin lesions had been caused by Wydex . The symptoms were eradicated after she changed her work environment and there has been no evidence of recurrence.

STATEMENT OF PROBLEM: Use of custom tray and tray adhesive is clinically recommended for elastomeric impression material. However there is not clear mention of drying time of tray adhesive in achieving appropriate bonding strength of tray material and impression material. PURPOSE: This study is to investigate an appropriate drying time of tray adhesives by evaluating tensile bonding strength between two types of polyvinylsiloxane impression materials and resin tray, according to various drying time intervals of tray adhesives, and with different manufacturing company combination of impression material and tray adhesive. MATERIAL AND METHODS: Adhesives used in this study were Silfix (Dentsply Caulk, Milford, Del, USA) and VPS Tray Adhesive (3M ESPE, Seefeld, Germany) and impression materials were Aquasil Ultra (monophase regular set, Dentsply Caulk, Milford, Del, USA) and Imprint II Garant (regular body, 3M ESPE, Seefeld, Germany). They were used combinations from the same manufacture and exchanged combinations of the two. The drying time was designed to air dry, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes. Total 240 of test specimens were prepared by auto-polymerizing tray material (Instant Tray Mix, Lang, Wheeling, Il, USA) with 10 specimens in each group. The specimens were placed in the Universal Testing machine (Instron, model 3366, Instron Corp, University avenue, Nowood, MA, USA) to perform the tensile test (cross head speed 5 mm/min). The statistically efficient drying time was evaluated through ANOVA and Scheffe test. All the tests were performed at 95% confidence level. RESULTS: The results revealed that at least 10 minutes is needed for Silfix-Aquasil, and 15 minutes for VPS Tray Adhesive-Imprint II, to attain an appropriate tensile bonding strength. VPS Tray Adhesive-Imprint II had a superior tensile bonding strength when compared to Silfix-Aquasil over 15 minutes. Silfix-Aquasil had a superior bonding strength to VPS Tray Adhesive-Aquasil, and VPS Tray Adhesive-Imprint II had a superior tensile bonding strength to Silfix-Imprint II at all drying periods. CONCLUSION: Significant increase in tensile bonding strength with Silfix-Aquasil and VPS Tray adhesive-Imprint II combination until 10 and 15 minutes respectively. Tray adhesive-impression material combination from the same company presented higher tensile bonding strength at all drying time intervals than when using tray adhesive-impression material of different manufactures.

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by sudden-onset headache with focal neurologic deficit and prolonged but reversible multifocal narrowing of the distal cerebral arteries. Stroke, either hemorrhagic or ischemic, is a relatively frequent presentation in RCVS, but progressive manifestations of subarachnoid hemorrhage, intracerebral hemorrhage, cerebral infarction in a patient is seldom described. We report a rare case of a 56-year-old woman with reversible cerebral vasoconstriction syndrome consecutively presenting as cortical subarachnoid hemorrhage, intracerebral hemorrhage, and cerebral infarction. When she complained of severe headache with subtle cortical subarachnoid hemorrhage, her angiography was non-specific. But, computed tomographic angiography showed typical angiographic features of this syndrome after four days. Day 12, she suffered mental deterioration and hemiplegia due to contralateral intracerebral hematoma, and she was surgically treated. For recurrent attacks of headache, medical management with calcium channel blockers has been instituted. Normalized angiographic features were documented after 8 weeks. Reversible cerebral vasoconstriction syndrome should be considered as differential diagnosis of non-aneurysmal subarachnoid hemorrhage, and repeated angiography is recommended for the diagnosis of this under-recognized syndrome.

We have performed recession of all 4 rectus muscle in 8 eyes with neovascular or absolute glaucoma. The visual acuity of these eyes ranged fram no light perception to recognition of hand motion. As the purpose of surgery was to destroy all anterior ciliary arteries from the rectus muscles, after performing 2mm recessions on all 4 rectus muscles we applied cryotherapy on the oclera from he original rite to the mear insertion site. The cases were followed up for periods ranging from 3 to 19 months, with an average of 10.3 months. At the end of follow-up periods, we observed a statistically significant drop (p<0.05) in the intraocular pressure level, from the preoperative leveI of 49.8 +/- 7.9 mmHg (mean +/-SD) to 36.6 +/- 18.1 mmHg without any additional medical therapy. However, the decreases were not notable. In the treatment of neovascular glaucoma for absolute glaucoma, we have found that simultaneous disruption of all anterior ciliary arteries through anterior segment ischemia will not result in a satisfactory decrease in postoperative intraocular pressure.
