The author experienced a case of orbital meningioma, which originated in the right orbit of a 16-year-old Korean boy. At his first visit, loss of vision and proptosis in the right eye were complained. On ophthalmoloic examination the right eye had the visual acuity of zero, the limited eyeball movement to all directions, straight forward proptosis of 22 mm, and pale optic disc. The left eye was normal. Kronlein operation was performed because the tumor seemed to be localized within the right orbit without any evidence of intracranial extension. Histologic examination confirmed the lesion to be mixed type meningioma.

On 2,372 ophthalmic patients that received ocular examination and treatment by the author's medical service intended for doctor less farming and island villages, analyses were done according to disease entity, age, sex and district. The results were as follows: 1. Of the 2,372 patients, male was 384 (25.4%) and female 1,129 (74.6% and total 1,513 in farming districts, male 356 (41.4%) and female 503 (58.6%) and total 859 in island districts. Female far outnumbered male. 2. The most common ocular disease is pterygium (458 of 1,513, 30.3%) in farming districts and chronic catarrhal conjunctivitis (249 of 859, 29.0%) in island districts. 3. Of the pterygium patients, male was 77 (16.8%) and female 381 (83.2%) of 458 (30.3%) in farming districts, male 37 (30.3%) and female 85 (69.7%) of 122 (14.2%) in island districts. There was predominantly high incidence in farming districts, female and the age groups of the fifth and sixth decade. 4. In the nasolaorimal duct obstruction patients, male was 16(17.2%) and female 77(82.8%) of 93 (6.1%) in farming districts, male 12 (27.3%) and female 32 (72.7%) of 44 (5.l%) in island districts. There was no significant difference of the incidence in both districts, but mostly they were female and the age group from the fifth to seventh decade. 5. Of the cataract patients, male was 20 (24.7%) and female 61 (75.3%) of 81 (5.4%) in farming districts, male 10 (38.5%) and female 16 (61.5%) of 26 (3.0%) in island districts. There showed significant high incidence over age 50. 6. In the glaucoma patients, male was 3 (33.3%) and female 6 (66.7%) of 9 (0.6%) in farming districts, male 2 (40.0%) and female 3 (60.0%) of 5 (0.6%) in island districts. 7. Of the trachoma patients, male was 2 (28.6%) and female 5 (71.4%) of 7 (0.5%) in farming districts, male 24 (42.9%) and female 32 (57.1%) of 56 (6.5%) in island districts. Island districts and female were more predominant. 8. Of the 694 cases that required operation, only 287 (41.4%) received surgical procedures and on concerning to pterygium which was the majority, operations were done in 208 (35.9%) of cases.

We examined visual acuity and refractive state of 1,522 children (904 boys and 618 girls) in the 6th grade of the primary school in the center of Kwangju city, and of 1,318 children(711 boys and 607 girls) in the outskirts. To evaluate environmental factors, the statistical comparative study in two groups about visual acuity and refractive state including the data from the questionnaires answered by parentr was done. The results were as follows: 1. The incidence of subnormal visual acuity was 20.5%. It was higher in girls (25.9%) than in boys (16.3%), and higher in the school in the center (22.7%) of the city than in the outskirts (17.9%). Especially, in girls, it was significantly low in the outskirts (21.4%) comparing to the center (30.3%). 2. In the relationship between the incidence of subnormal visual acuity and posture, the incidence was higher in the children who have a poor carriage during studying(24.6%) than in the children who have a fine carriage (19.9%) and it was markedly higher in girls (30.7%) than in boys (19.7%). 3. The incidence of subnormal visual acuity was higher in the children who maintained inadequate distance from the TV set (24.1% ) than in the children who maintained adequate distance (19.6%), and it was higher in girls (31.3%) than in boys (17.8%). 4. The incidence of subnormal visual acuity was similar in the children who had balanced diet (21.6%)and the children who had one-sided diet (22.8%). 5. Refractive state of the eyes with subnormal visual acuity was myopic in 17.0%, hyperopic in 3.0% and mixed astigmatic in 0.3%. The incidence of myopic eyes was higher in girls (21.3%) than in boys (13.8%). 6. Occurrence of the eyes which returned from abnormal refractive state to emme tropia by instillation of 5% homatropine solution was similar in boys (5.2%) and girls (6.9%) and the eyes were considered to be pseudomyopic.

Carcinoid tumors of the intestinal tract are uncommon neoplasms thought to arise from argentaffin cells in the base of the intestinal crypts. Carcinoid tumors of other sites have since been reported with increasing frequency. We experienced one case of rectal carcinoid tumor and the other case of stomach carcinoid turnor. A 52-year-old male patient was admitted to the hospital because of right upper abdominal discomfort. On the CT scan, multiple low density masses were noticed. Sigmoidoscopy revealed the whitish yellow ulcerofungating mass which had vague margin. And a 31-year-old male patient was admitted to the haspital because of hematemesis. On the gastrofiberscopic examination, an ovoid shallow ulcer crater which had elevated margin, smooth tapered fold and vissible vessel was noticed on the anterior wall side of the high body. The biopsy specimen in both these cases showed carcinoid cells. 24h urine 5-HIAA of these cases was negative. Awareness of carcinoid tumor in differential diagnosis of hepatic metastasis and of gastric ulcer is necessary.

Among the sympathetic blocks used to treat various symptoms and diseases, including sympathetic dysfunction in pain clinics, a stellate ganglion block (SGB) is one of the easiest to apply. However, it is difficult to evaluate the effects of SGB due to the subjective nature of patient-reported data. A 26-year-old female, who presented with symptoms of coldness and sweating on both hands, received SGB 25 times on each side over a 2-month period. The effects of SGB were followed up using a cold stress test with thermography. Although the symptoms appeared again after 6 months, the recovery rate of the palmar temperature after the cold stress test improved significantly and was maintained for 18 months.

PURPOSE: This study was conducted to compare the cumulative survival rates (CSRs) and the incidence of postloading complications (PLCs) between a bone-level internal connection system (ICS-BL) and an external connection system (ECS). METHODS: The medical records of patients treated with either a ICS-BL or ECS between 2007 and 2010 at Asan Medical Center were reviewed. PLCs were divided into two categories: biological and technical. Biological complications included >4 mm of probing pocket depth, thread exposure in radiographs, and soft tissue complications, whereas technical complications included chipping of the veneering material, fracture of the implant, fracture of the crown, loosening or fracture of the abutment or screw, loss of retention, and loss of access hole filling material. CSRs were determined by a life-table analysis and compared using the log-rank chi-square test. The incidence of PLC was compared with the Pearson chi-squared test. RESULTS: A total of 2,651 implants in 1,074 patients (1,167 ICS-BLs in 551 patients and 1,484 ECSs in 523 patients) were analyzed. The average observation periods were 3.4 years for the ICS-BLs and 3.1 years for the ECSs. The six-year CSR of all implants was 96.1% (94.9% for the ICS-BLs and 97.1% for the ECSs, P=0.619). Soft tissue complications were more frequent with the ECSs (P=0.005) and loosening or fracture of the abutment or screw occurred more frequently with the ICS-BLs (P<0.001). CONCLUSIONS: Within the limitations of this study, the ICS-BL was more prone to technical complications while the ECS was more vulnerable to biological complications.

BACKGROUND: Administering extracorporeal membrane oxygenation (ECMO) to critically ill patients with acute respiratory distress syndrome has substantially increased over the last decade, however administering ECMO to patients with hematologic malignancies may carry a particularly high risk. Here, we report the clinical outcomes of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO. METHODS: We performed a retrospective review of the medical records of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO at the medical intensive care unit of a tertiary referral hospital between March 2010 and April 2015. RESULTS: A total of 15 patients (9 men; median age 45 years) with hematologic malignancies and severe acute respiratory failure received ECMO therapy during the study period. The median values of the Acute Physiology and Chronic Health Evaluation II score, Murray Lung Injury Score, and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score were 29, 3.3, and -2, respectively. Seven patients received venovenous ECMO, whereas 8 patients received venoarterial ECMO. The median ECMO duration was 2 days. Successful weaning of ECMO was achieved in 3 patients. Hemorrhage complications developed in 4 patients (1 pulmonary hemorrhage, 1 intracranial hemorrhage, and 2 cases of gastrointestinal bleeding). The longest period of patient survival was 59 days after ECMO initiation. No significant differences in survival were noted between venovenous and venoarterial ECMO groups (10.0 vs. 10.5 days; p = 0.56). CONCLUSIONS: Patients with hematologic malignancies and severe acute respiratory failure demonstrate poor outcomes after ECMO treatment. Careful and appropriate selection of candidates for ECMO in these patients is necessary.

PURPOSE: Developments in micro/macrostructures of implants and surgical techniques brought out stable outcomes of implant dentistry. The aim of this study was to evaluate the distributions of implant patients, the types of implanted sites, and the success or survival rates of various implant systems and to analyze the implant placement done at each specificintraoral site and situation. MATERIALS AND METHODS: The data of dental implantations collected between 1992 and 2006 at the Department of Periodontology in 00000 University Hospital were analyzed. RESULTS: 1. Largest part of the patients were at the age of 40s and 50s in bothgender who lost their teeth mostly by periodontaldiseases and caries at the posterior intraoral sites as major ones. Bone densities of type II(mandible) and III(maxilla) were likely to be seen with quantity of type B. Lengths of the implants between 10 and 15 mm and wide platform took the largest part. 2. Survival rates of Implantium(R)(98.8%), Xive(R)(100%) and ITI TE(R)(100%) were high when Frialit-2(R) showed 82%(poor bone density area) or 87.2%(combined with additional therapy). IMZ(R) had lowest cumulative survival(67.5%) and success rate(49.4%) amongst all. 3. Replacement with 2 wide or 3 regular platforms showed no significant differences in survival rate and marginal bone loss atmandibular posterior area. In single restoration of mandibular second molar, 5-year success rate of machined surface Branemark(R)(70.37%) was lower than that of rough surface ITI(R) SLA(100%). 4. Replacement of single tooth in anterior area showed high survival rate of 94.5%. 5. The success rates of Branemark Ti-Unite and ITI SLA at posterior maxilla with poor bone density both showed stable outcomes. 6. 10-year cumulative survival rate of implants with maxillary sinus augmentation by lateral window approach appeared to be 96.60%. Low survival rate(75%) was shown when there were more than two complications combined. Height of grafted bone remained stable above the implant apex. CONCLUSIONS : Rough surfaced implants showed stable outcomes in most of the situation including poor bone density and additional therapy combined.

Bone morphogenetic proteins have been shown to possess significant osteoinSductive potential, but in order to take advantage of this effect for tissue engineering, carrier systems are essential. Successful carrier systems must enable vascular and cellular invasion, allowing BMP to act as a differentiation factor. The carrier should be reproducible, non-immunogenic, moldable, and space-providing, to define the contours of the resulting bone. The purpose of this study was to review available literature, in comparing various carriers of BMP on rat calvarial defect model. The following conclusions were deduced. 1. Bone regeneration of ACS/BMP, beta-TCP/BMP, FFSS/BMP, FFSS/beta-TCP/BMP, MBCP/BMP group were significantly greater than the control groups. 2. Bone density in the ACS/BMP group was greater than that in beta-TCP, FFSS, FFSS/beta-TCP carrier group. 3. Bone regeneration in FFSS/BMP group was less than in ACS/BMP, beta-TCP/BMP, MBCP/BMP group. However, New bone area of FFSS/beta-TCP/BMP carrier group were more greater than that of FFSS/BMP group. ACS, beta-TCP, FFSS, FFSS/beta-TCP, MBCP were used for carrier of BMP. However, an ideal carrier which was reproducible, non-immunogenic, moldable, and space-providing did not exist. Therefore, further investigation are required in developing a new carrier system.
