Multiple tooth loss can cause disharmonious occlusial plane, loss of vertical dimension and deflection of mandibular movement. Therefore, restoring proper vertical dimension and occlusion in the centric relation is an important treatment goal. Implant-assisted removable partial denture is a recently used clinical technique, because it increases patient satisfaction by improving retention, support, and stability of conventional denture. The objective of this article is to present a case report describing the fabrication of treatment denture and implant assisted removable partial denture using previously placed implants for a patient with partial loss of posterior support and anterior stop.

Purpose: To analyze the intraocular pressure (IOP) lowering effect, prognostic factors, and complications that occurred after iStent inject® or XEN® implantation in South Korea. Methods: We retrospectively analyzed 83 eyes with glaucoma who were followed-up for more than 6 months after iStent inject® or XEN® implantation alone or combination with cataract surgery. The success of surgery was defined as an IOP ≤21 mmHg and IOP reduction ≥20% from preoperative IOP. Results: The average IOP drop rate for 6 months after surgery was 33.80% for iStent inject® (group A, 24 eyes), 24.91% for XEN® (group B, 15 eyes), 20.47% for combined iStent inject® and cataract surgery (group A-1, 32 eyes), and 30.39% for combined XEN® and cataract surgery. The cumulative success rate of 6 months after surgery was 45.5% ± 11.2% for group A, 52.8% ± 15.4% for group B, 51.9% ± 9.0% for group A-1, and 83.3% ± 10.8% for group B-1. The difference in success rates between groups A and B was not statistically significant (p = 0.574), and also between groups A-1 and B-1 (p = 0.079). Conclusions iStent inject® and XEN® both have a significant effect on lowering IOP, regardless of combining cataract surgery. XEN® implantation led to a statistically significant reduction in IOP lowering medications.

PURPOSE: The goal of this study was to evaluate the clinical anitplaque and antigingivitis effects of a mouthrinse containing cetylpyridinium chloride (CPC), triclosan and dipotassium glycyrrhizinate (DPZ) in patients with gingivitis and mild periodontitis. METHODS: Thirty-two subjects were randomized into 2 groups. The test group used a mouthrinse containing 0.05% CPC, 0.02% triclosan and 0.02% DPZ, while the control group used a placebo mouthrinse. At baseline, 2 weeks and 4 weeks, the papillary bleeding index (PBI), Turesky-Quigley-Hein plaque index (PI) and Loe-Silness gingival index (GI) were assessed. During the experimental period, the patients used the mouthrinse for 30 seconds, 4 to 5 times/day (10 mL/time) within 30 minutes after toothbrushing. RESULTS: No adverse effects appeared in either the experimental or the control group. Regarding PBI, PI and GI values, statistical significance was detected between values at baseline and 2 weeks for both groups (P<0.05). In the experimental group, statistically significantly lower values were detected at 4 weeks compared to at 2 weeks. However, in the control group, no statistically significant difference was detected between the values at 2 weeks and 4 weeks. Additionally, the mean value after 4 weeks for the control group was slightly higher than the mean value after 2 weeks for the control group. CONCLUSIONS: This study for 4 weeks demonstrated that mouthrinses containing CPC, triclosan and DPZ may contribute to the reduction of supragingival plaque and gingivitis.

Because sublingual region is well-vascularized and sublingual artery is passed throughout this region, it should be careful not to perforate lingual cortex when placing dental implant on mandible. A 83-years-old male complained severe sublingual hematoma, hemorrhage and dyspnea came our outpatient department. He had received dental implant placement in the same day. He needed hemostasis and airway control. If soft tissue of sublingual region and the artery are injured, it may result in life-threatening excessive hemorrhage. In dental implant surgery, especially mandible, we should recognize the accurate shape of mandible and anatomy of sublingual region. It is important to stop anticoagulant agent before surgery. When a patient has airway obstruction, the operator should manage airway quickly.

BACKGOUND: The elderly have increased sensitivity to opioids and anesthetics. The hemodynamic effects of propofol- remifentanil during induction are not known in the elderly. This study was designed to compare two different remifentanil administration methods during propofol-remifentanil induction and tracheal intubation in the elderly. METHODS: Forty patients, ages over 65 years were enrolled. Anesthesia was induced with propofol 1 mg/kg and remifentanil. In Group T (TCI : target controlled infusion), remifentanil 3.5 ng/ml were infused until laryngoscopy and tracheal intubation. In Group R (rapid infusion), infusion were stopped when effect-site concentration reaches 5.0 ng/ml. Mean arterial pressure (MAP) and heart rate (HR) were recorded before induction (baseline), after remifentanil reaches its target effect-site concentration, after administration of propofol, 1 minute before intubation, 1 minute after intubation and 3 minute after intubation. RESULTS: In both groups, MAP decreased significantly after induction and then increases significantly after intubation (P < 0.05). In Group R, MAP decreased earlier and was significantly lower than that of Group T (P < 0.05) before intubation. HR shows no significant changes between groups. CONCLUSIONS: In these two methods, there are no severe hemodynamic compromise during induction and tracheal intubation in the elderly. However, lesser degree of hypotension occurs in Group T. So we conclude that TCI method can provide better hemodynamic stability than rapid infusion method.

PURPOSE: We investigated the effect of VEGF usage and the method of surgery on the vascularization rate of the porous orbital implant (Medpor(R)). METHODS: Thirty six Newzealand white rabbits were randomized into 2 groups according to the method of surgery (evisceration and intrascleral implantation and evisceration and retroscleral implantation). Each group was subdivided into two groups, a group treated with VEGF, and the other without VEGF treatment. The degree of vascularization was observed in the four groups at 1, 2, 4 weeks by using cryofilm transfer kit (Finetec, Tokyo, Japan). The implant was sliced at the equator with cryomicrotome and stained with Hematoxylin and Eosin, Masson's trichrome and reticulin. The sample was observed to assay the degree of fibrovascular ingrowth with light microscope. RESULTS: The group in which VEGF was used and the implant was inserted retrosclerally (n=9) showed significantly higher vascularization rate than the other three groups (P<0.05). Vascularization rate of the implant was significantly higher in the group in which VEGF was used (n=18). The rate was 83.6% compared to 64.2% in the control group (P<0.05). Different methods of surgery also showed significant difference. The rate of vascularization was 64.8% in the intrascleral inserted group (n=18) compared to 82.9% in the retroscleral inserted group (P<0.05). However, there was no difference in the vasculariztion rate at different time of observation (p>0.05). CONCLUSIONS: After using VEGF or inserting the implant retrosclerally, the vascularization of the implant was significantly incresed.

OBJECTIVE: The authors present experience of treatment on the patients who suffered from epileptic seizures with ischemic stroke in their childhood. METHODS: We reviewed the clinical characteristics, neuroimaging findings, and electroencephalographic records of thirteen patients who suffered from seizures with stroke in childhood. Ten patients were improved to be seizure-free or to fall into only rare seizures with appropriate anticonvulsant medication. Three of these patients showed medical intractability in spite of appropriate multi-drug therapy, so they were carefully evaluated to consider the candidate for epilepsy surgery based on our sophisticated presurgical studies. Surgical intervention was performed in these selected 3 cases according to intracranial recordings with subdural grids, who had focal electroencephalographic abnormalities in diffuse cortical lesions. RESULTS: The series included 8 women and 5 men with ages at seizure onset ranging from 3 to 38 years (mean 14.3 years). Cerebral ischemia was caused by various life threatening early insults including febrile convulsion, difficult delivery, viral meningoencephalitis, near drowning, and severe dehydration. Simple partial seizure with or without secondary generalization was most commonly noted. Magnetic resonance image revealed a wide variation in size, shape, and location of the infarcted areas. Major vascular territory and watershed area infarction involving diffuse cerebral cortex was a powerful cause of post-stroke seizure. Excellent clinical result was achieved even in the patients who underwent surgery. CONCLUSION: Control of late onset seizures related to childhood cerebral infarction is not a trivial one, because of its wide, sometimes multilobar territories. However, enthusiastic medical trial as well as comprehensive surgical consideration is essential for better seizure control related to quality of life.

PURPOSE: Relapsing polychondritis is a progressive inflammatory disorder of unknown cause affecting predominantly the cartilage of the ears, nose, and tracheobronchial tree as well as internal structures of the eyes and nose. Episcleritis is the most common ocular manifestation. We experienced a case of relapsing polychondritis with episcleritis and it's treatment. Therefore, we report this case with literature review. METHODS: Seventy-year-old woman presented with ocular pain and redness in right eye which had developed one week before. She had bilateral auricular chondritis, vertigo, saddle nose deformity, polyarthritis and respiratory difficulty. Relapsing polychondritis was diagnosed by typical clinical features. RESULTS: The patient was started on systemic steroid therapy and 0.1% dexamethasone in the right eye four times daily as well as oral ibuprofen 600 mg four times daily, which were slowly tapered off over the next four weeks with the resolution of the episcleritis.
