PURPOSE: To report the clinical outcomes of a volar plate reinforcing technique with free tendon grafts after sesamoid excision for the surgical treatment of subsesamoid arthritis of the metacarpophalangeal (MCP) joint of the thumb. MATERIALS AND METHODS: Eleven consecutive patients that underwent sesamoid excision and volar plate reinforcement using a palmaris longus free tendon graft were enrolled. There were 7 males and 4 females, with an average age of 46 (range, 30-56 years). Post-traumatic arthritis after a hyperextension injury of the thumb was present in 9 patients. Two patients had idiopathic arthritis. All patients were evaluated by objective and subjective criteria, the mean follow-up duration was 19 months (range, 12-35 months). RESULTS: The results were satisfactory overall (3 excellent, 7 good, 1 poor). The mean grip strength and pinch strength significantly improved from 63.0% and 51.3%, respectively, preoperatively, to 84.9% and 88.9%, postoperatively. The mean range of motion for the MCP joint was -5.9/50.9 degrees. The mean DASH and MHQ scores showed significant improvement compared to the preoperative scores. CONCLUSION: The early clinical results suggest that the described technique is a safe and effective option for subsesamoid arthritis of the MCP joint of the thumb.

PURPOSE: To report a case of inadvertent anterior chamber and cornea stromal injection with high dose antibiotics and steroids during cataract operation. METHODS: During cataract operation on a 78 year-old female patient, high dose gentamicin (20 mg/0.5 ml) and dexamethasone (2 mg/0.5 ml) were inadvertently injected into the anterior chamber and cornea stroma when making cornea edema for sealing of the incision sites. Anterior chamber irrigation with balanced salt solution (BSS) was immediately administered. On postoperative day one, extensive cornea edema was noted, and best-corrected visual acuity was 0.2. Descemet's membrane folds were observed around the corneal incision sites. Topical 5% NaCl and 1% prednisolone were started. RESULTS: Four weeks postoperatively, corneal edema began to reduce significantly. At four months postoperatively, corneal edema fully resolved, and best-corrected visual acuity was 0.8. However, some Descemet's membrane folds still remained, and a decrease in the number of endothelial cells was noted by specular microscope. CONCLUSIONS: In this case involving anterior chamber and cornea stromal injection with high dose antibiotics and steroids, immediate anterior chamber irrigation with balanced salt solution seemed an appropriate management, and the patient's long-term visual acuity appears good. To prevent such mistakes, precise labeling of all solutions and use of different syringe needles should be considered.

BACKGROUND: Cardiac tamponade is associated with the expiratory increase and the expira-tory decrease in left ventricular filling flow. With Doppler echocardiography, we analyzed the respiratory variations of mitral and tricuspid inflows, and pulmonary and hepatic venous flows in patients with cardiac tamponade. METHODS: Respiratory hemodynamic changes in mitral and tricuspid inflows and pulmonary and hepatic venous flows were evaluated using Doppler echocardiography in 13 patients (6 men and 7 women; mean age 51+/-13 years) with large pericardial effusion and clinical cardiac tamponade, and compared the results with those of 11 control subjects (3 men and 8 women, mean age 53+/-13 years). Doppler examination was repeated after pericardiocentesis in 6 patients. RESULTS: Peak velocity of early diastolic mitral inflow (E velocity) decreased during inspiration compared with expiratory increase; the mean percentage change was 40%. Peak velocity of late diastolic mitral inflow (A velocity) decreased 13% during inspiration. E/A ratio decreased 31% during inspiration. Deceleration time (DT) and isovolumic relaxation time (IVRT) increased by 26% and 44%, respectively, during inspiration. But respiratory variations of tricuspid inflow were opposite to those of mitral inflow. Tricuspid E velocity increased during inspiration and decre-ased during expiration. The mean percentage change was 123%, which was larger than thte 40% of mitral inflow. The most characteristic findings of pulmonary venous flow during respiration were the expiratory increases of peak diastolic velocity (DV) and diastolic time-velocity integral (D-TVI). The mean percentage changes of peak systolic velocity (SV), DV and D-TVI during respiration were 27%, 45% and 53% respectively. In contrast, the SV and DV of hepatic venous flow increased during inspiration and decreased during expiration. The respiratory variations of peak systolic reverse flow velocity (SR) and peak diastolic reverse flow velocity (DR) were opposite to those of SV and DV. DR notably increased during expiration, and the mean percentage change was 61%. The ratio of RFI (Inspiratory reverse flow integral) to FFI (forward flow integral) of the tamponade group was 270%. The mean percentage changes of each parameters decreased after pericardiocentesis. CONCLUSION: Patients with cardiac tamponade showed inspiratory increases of diastolic tri-cuspid filling flow and hepatic forward flow. Expiratory increases included diastolic mitral filling flow, pulmonary venous systolic and diastolic flow, and hepatic venous reverse flow. Such res-piratory variations decreased after pericardiocentesis.

BACKGROUND/AIMS: There have been only few studies on the population-adjusted seroprevalence of HBV and HCV and on the change of them for more than 10 years in Korea. Therefore, this study was performed to evaluate them at a single health center in Daegu and Gyeongbuk province considering the population composition ratio. METHODS: We analyzed the seromarkers of HBV and HCV of 6,237 randomly sampled adults who had received health screening at the health promotion center in Dongsan hospital during the periods from year 1997 to 1999 (Period A) and from 2007 to 2009 (Period B). RESULTS: The seroprevalences of HBsAg, anti-HBs, anti-HBc and anti-HCV were 4.8%, 70.2%, 47.4%, and 0.5%, respectively. There is no difference in the seroprevalence of HBsAg between period A and B. However, downward tendency of prevalence through A to B from 6.8% to 4.5% could be found in 40s, and upward tendency from 4.7% to 6.8% in 50s. As for the seroprevalence of anti-HCV, although there was no difference through A to B, for 50s, it decreasd from 2.0% to 0.3% (p=0.007). However, for 60s, it increased as much as decreasd for 50s. CONCLUSIONS: The seroprevalence of HBsAg in Daegu/Gyeongbuk province was 4.8% and showed no difference through the time period of 10 years. The seroprevalence of anti-HCV was 0.5% and also showed no difference through the time periods.

PURPOSE: To investigate biomechanical properties of the cornea using a dynamic Scheimpflug analyzer according to age. MATERIALS AND METHODS: In this prospective, cross-sectional, observational study, participants underwent ophthalmic investigations including corneal biomechanical properties, keratometric values, intraocular pressure (IOP), and manifest refraction spherical equivalent (MRSE). We determined the relationship of biomechanical parameters and ocular/systemic variables (participant's age, MRSE, IOP, and mean keratometric values) by piecewise regression analysis, association of biomechanical parameters with variables by Spearman's correlation and stepwise multiple regression analyses, and reference intervals (RI) by the bootstrap method. RESULTS: This study included 217 eyes of 118 participants (20–81 years of age). Piecewise regression analysis between Corvis-central corneal thickness (CCT) and participant's age revealed that the optimal cut-off value of age was 45 years. No clear breakpoints were detected between the corneal biomechanical parameters and MRSE, IOP, and mean keratometric values. Corneal velocity, deformation amplitude, radius, maximal concave power, Corvis-CCT, and Corvis-IOP exhibited correlations with IOP, regardless of age (all ages, 20–44 years, and over 44 years). With smaller deformation amplitude and corneal velocity as well as increased Corvis-IOP and Corvis-CCT, IOP became significantly increased. We provided the results of determination of confidence interval from RI data using bootstrap method in three separate age groups (all ages, 20–44 years, and over 44 years). CONCLUSION: We demonstrated multiple corneal biomechanical parameters according to age, and reported that the corneal biomechanical parameters are influenced by IOP.

The cDNA nucleotide sequence of genome segment B encoding the VP1 protein was determined for the aquatic birnavirus GC1 isolated from the rockfish Sebastes schlegeli in Korea. The VP1 protein of GC1 contains a 2,538 bp open reading frame, which encodes a protein comprising 846 amino acid residues that has a predicted MW of 94 kDa. The sequence contains 6 potential Asn-X-Ser/Thr motifs. Eight potential Ser phosphorylation sites and 1 potential Tyr phophorylation site were also identified. GC1 contains the Leu-Lys-Asn (LKN) motif instead of the typical Gly-Asp- Asp (GDD) motif found in other aquatic birnaviruses. We also identified the GLPYIGKT motif, the putative GTPbinding site at amino acid position 248. In total, the VP1 regions of 22 birnavirus strains were compared for analyzing the genetic relationship among the family Birnaviridae. Based on the deduced amino acid sequences, GC1 was observed to be more closely related to the infectious pancreatic necrosis virus (IPNV) from the USA, Japan, and Korea than the IPNV from Europe. Further, aquatic birnaviruses containing GC1 and IPNV have genogroups that are distinct from those in the genus Avibirnaviruses and Entomo-birnaviruses. The birnavirusstrains were clustered into 5 genogroups based on their amino acid sequences. The marine aquatic birnaviruses (MABVs) containing GC1 were included in the MABV genogroup; the IPNV strains isolated from Korea, Japan, and the USA were included in genogroup 1 and the IPNV strains isolated primarily from Europe were included in genogroup 2. Avibirnaviruses and entomobirnaviruses were included in genogroup 3 and 4, respectively.
