The treatment of patients with severe periodontitis should be proceeded step-bystep through an accurate diagnosis of each patients’ individual tooth and with a strategic treatment plan. Implant-supported fixed prosthetic restoration has the advantage of high patient satisfaction and stable vertical dimension compared to the removable partial denture. However, multiple teeth defect areas lacking hard tissue may be disadvantageous in aesthetic failure and longer treatment time. In addition, it takes a certain period of time to manufacture and install a conventional fixed prosthesis, and during this process, the provisional prosthesis must satisfy the mechanical, biological, and aesthetic requirements of teeth. The purpose of this article is to describe the fabrication of implant-supported fixed prosthesis through a step-by-step approach in a partially edentulous patient.

Background:
Robot-assisted laparoscopic radical prostatectomy is an advanced and popular surgical technique. However, increased intracranial pressure which is caused by CO2 pneumoperitoneum and Trendelenburg position is the main cerebrovascular effect. Measurement of optic nerve sheath diameter using ocular ultrasound is a noninvasive and reliable method for the assessment of intracranial pressure. The primary endpoint of this study was to identify whether low blood pressure regulation has any benefit in attenuating an increase of optic nerve sheath diameter during robot-assisted laparoscopic radical prostatectomy.
Methods:
Optic nerve sheath diameter and cerebral oxygen saturation were measured at baseline (supine position), one and two hours after pneumoperitoneum and Trendelenburg position respectively, and after return to supine position in normal (n = 27) and low blood pressure groups (n = 24).
Results:
Mean optic nerve sheath diameter values measured at one and two hours after pneumoperitoneum and Trendelenburg position were significantly increased compared to the baseline value (P < 0.001 in normal blood pressure group; P = 0.003 in low blood pressure group). However, the mean optic nerve sheath diameter and cerebral oxygen saturation measured at any of the time points as well as degrees of change between the two groups did not show any significant changes. The peak values of optic nerve sheath diameter in normal and low blood pressure groups demonstrated 14.9% and 9.2% increases, respectively.
Conclusions
Low blood pressure group demonstrated an effect in maintaining an increase of optic nerve sheath diameter less than 10% during CO2 pneumoperitoneum and Trendelenburg position.

BACKGROUND: Serum eosinophil cationic protein(ECP) level has been proposed as a indirect marker of eosinophilic inflammation of the airway in bronchial asthma. OBJECTIVE: To evaluate serum ECP against indirect clinical markers of disease, we compared bronchial obstruction, bronchial hyperresponsiveness and peripheral blood eosinophil counts, total IgE with serum ECP levels in patients with bronchial asthma and normal controls. METHOD: Fourty-two patients with bronchial asthma and twenty-six normal controls were enrolled. Measurement were made by spirometry, inhalation challenge with methacholine, peripheral blood eosinophil counts, total IgE and FEIA(fluoroenzymatic immunoassay) of serum ECP RESULT: Serum ECP levels were significantly higher in asthmatic patients than normal controls(p<0.0,5). Serum ECP levels were correlated with peripheral blood eosinophil counts(p<0.01, r=0.544) and bronchial hyperresponsiveness(PC,)(p<0.01, r=-0.456) in patients with bronchial asthma. Serum ECP levels were correlated with degree of bronchial obstruction(FEV, % to predicted value, FEV1/FVC%) in total subjects, but not in asthmatic patients. CONCLUSION: Serum ECP level may be used as indicator of disease activity in bronchial asthma and be helpful in differentiation between normal person and asthmatic patients on simple serological method. Further studies on the changes of serum ECP levels according to disease course and therapeutic responses are needed.

Temporomandibular Joint (TMJ) dislocation due to tongue cancer operation has a potential risk factor in that it may become a chronic anterior dislocation. In this regard, the treatment methods of TMJ dislocation are more complicated than that of the usual manual reduction therapy. To prevent the reduction procedure from becoming more complicated, clinicians should check the TMJ status afterward the head and neck operations. But, even with caution, chronic dislocation can happen. To restore normal jaw relation in these patients, one can be treated by manual reduction, open surgery under general anesthesia, and by fastening of additional intermaxillary fixations. Here we report two successfully treated cases of TMJ dislocations due to tongue cancer operation, one treated by the conservative method, and the other by the open surgery method.

The branchio-oto-renal (BOR) syndrome is a clinically and genetically heterogeneous disease entity which is characterized by the association of preauricular pits, branchial cleft anomaly, hearing loss and various renal anomalies. The incidence of BOR syndrome is approximately 1 : 40,000 and its genetic pattern of transmission is autosomal dominant. Hearing loss is the most common feature of BOR syndrome and is reported in almost 90% of affected individuals. EYA1, the human homologue of the Drosophila eyes absent gene, has been shown to cause BOR syndrome. We report, with a review of literatures, a female patient with BOR syndrome.

BACKGROUND: Obtaining a venous blood sample from infants and children can be a painful and traumatic procedure. It has been suggested that capillary blood samples can serve as substitutes for venous blood samples to diagnose anemia. However, few data exist about the correlation between the laboratory results obtained using capillary and venous blood samples. This study was performed to determine if the results from the LC-178CRP(TM) are the same as the results from a conventional hematology analyzer using venous blood. METHODS: After informed consent was obtained, paired venous and capillary blood sample were collected simultaneously from 104 children (M : F=50 : 54). The capillary blood was analyzed using the LC-178CRP(TM), and venous blood was analyzed using an automatic hematology analyzer. The following were compared from capillary and venous samples: CBC, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), red cell distribution width (RDW), and platelet count. The results were analyzed by Pearson's correlation and the Bland Altman Plot method. RESULTS: The hemoglobin values were similar between the two groups of samples and had a high coefficient correlation (r=0.877). White blood cells, hematocrit, MCV, and MCH also had a significant correlation between capillary and venous blood samples. Based on the Bland-Altman method, the agreement between the two methods was considered good. CONCLUSION: The hematologic results from the capillary blood had a close correlation with the conventional venous method, including white blood cell count, and hemoglobin, MCV, and MCH levels. The LC-178CRPtrade mark should be considered as an alternative for venous blood sampling for the tested parameters in children.

Backgound: The placement of stents in coronary arteries has been shown to reduce acute closure and restenosis in comparison to balloon angioplasty. However, clinical use of intracoronary stents is impeded by the subacute stent thrombosis and hemorrhagic complications associated with the anticoagulant regimen. It's known that the complete stent deployment with high pressure inflation and new antiplatelet agents are effective in reduction of subacute thrombosis and hemorrhage. So we evaluated initial results (success and complication rate) after high pressure-stent deployment with new anticoagulation protocol. METHODS: One hundred and ninety one patients with 201 lesions were treated with 231 stents of various types. The high pressure balloon inflation and antiplatelets agents were used in all cases. Final high pressure balloon inflation guided by IVUS were performed in 23 consecutive cases with incomplete stent deployment according to angiographic findings. RESULTS: 1) The indications of stenting (n=210) were De novo in 124 (59%), bailout procedure in 57 (27%), suboptimal result after PTCA in 19 (8%), and restenosis after PTCA in 14 (6%). The location of lesions were LAD in 101, RCA in 67, circumflex in 28, ramus intermedius in 3, and LMT artery in 2 lesions. Angiographic morphologic characteristics were type A in 2, type B in 158 (B1: 57, B2: 101), and type C in 22 lesions. 2) The angiographic and clinical success rate was 96% (192/201) and 92% (186/201) respectively. 3) In angiographic analysis, the baseline average reference vessel dirmeter was 3.33+/-0.35 mm. Baseline minimum lumen diameter (MLD) was 0.58+/-0.29 mm, with baseline percent diameter stenosis of 82.86+/-8.64%. The final stent diameter was 3.37+/-0.29 mm, with mean final percent stenosis of 0.63+/-8.25. The mean MLD after stenting was significantly increased (p<0.001). The mean MLD within stent increased 14%, from 2.91+/-0.39 mm at the nominal balloon inflation (inflation pressure=7 atm) to 3.37+/-0.29 mm at high pressure balloon inflation (inflation pressure <0A65B>12atm) (p<0.001). The length of lesions in GR I (cook), GR II, and Micro II stents were significantly longer than ones in PS, Cordis, Wiktor, Nir (p<0.001). 4) In intravascular ultrasound analysis, the mean lumen CSA at the tightest point within stent increased 11%, from 8.4+/-2.4 mm2 at the intial intravascular ultrasound to 9.4+/-2.1 mm2 at the final intravascular ultrasound (p<0.001). 5) The procedural and postprocedural complications were 2 acute closures associated with AMI and emergent CABG, 1 subacute closure which was revascularized by bail out stenting, 5 major hemorrhage requiring transfusion associated with 1 CVA and 2 metabolic acidosis induced by acute renal failure, and 5 death. CONCLUSION: The high pressure stent deployment procedure and new anticoagulation protocol associating tidopidine and aspirin without coumadin or prolonged heparin infusion allow us to obtain an acceptably low subacute thrombosis or bleeding complication rate. These results are encouraging and allow a wide use of coronary stenting.

Tuberous sclerosis is a rare multisystem syndrome characterized by hamartomatous tumors of the brain, skin, viscera, and eye. The diagnostic triad for this disease, proposed by Vogt, included epilepsy, mental retardation, and adenoma sebaceum. In eyes, retinal hamartomas and optic nerve phacoma are observed over 50% and hypopigmented areas of peripheral retina and iris are often found. We introduce an 18-year old girl with adenoma sebaceum of the face, history of epilepsy and insignificant mental retardation status. She also had a retinal hamartoma in her right eye, optic nerve phacoma in her left eye, shagreen patch on lumbosacral area, angiomyolipoma of both kidneys, periventricular subependymal nodules and calcified cortical nodule of occipital lobe of brain.
