We experienced a case of Ebstein's anomaly prenatally by fetal sonography. Ebstein's anomaly is a rare congenital heart defect characterized by abnormally downward displacement of the septal and posterior leaflets of the tricuspid valve. In the absence of tricuspid regurgitation, this condition may be completely asymptomatic. On the other hand, symptomatic newborns often develop life-threatening congestive heart failure. A 30-year-old multiparous woman was referred for the evaluation of fetal cardiac defect at 26th gestational week from a private clinic. Fetal ultrasonography showed markedly enlarged right atrium and downward displacement of tricuspid valve into the right ventricle. After discussion with the patient, the pregnancy was terminated and Ebstein's anomaly was confirmed by autopsy.

Total anomalous pulmonary venous confluence(TAPC), a rare cyanotic congenital anomaly of the heart especially in adult, is now diagnosed by echocardiography instead of cardiac catheterization with high sensitivity and specificity. The key points are identification of pulmonary veins, pulmonary venous confluence draining anomalously to the heart. RVDVO on M-mode, abnormal echo free space posterior to left atrium on 2D-echo are basic characteristics of TAPVC. Peak velocity and flow profile measurement on the doppler provide additional informations : obstruction and anomalous vessels. A case of 23 year old male with supracardiac type TAPVC diagnosed by echocardiography was corrected successfully by surgery.

A congenital ureteral valve is a rare disease, with the first case presented in 1887, since when, only 42 cases have subsequently been reported. From a review of the reported cases, this abnormality was often found to be associated with other urological disorders, such as vesicoureteral reflux, ectopic ureter, complete and incomplete duplication of the kidney, and contralateral renal atrophy. Here, the case of an adult patient with multiple congenital ureteral valves and renal atrophy is reported.

PURPOSE: To find the factors influencing the immediate and late outcome of replantation and revascularization of the digits, we carried out a prospective study from 1998 to 1999 with at least a 1-year followup. Traumatic total and subtotal amputations with inadequate circulation of the digits distal to the metacarpal head were included in the study. METHODS: This study was carried out as a prospective study from 1998 to 1999 with at least a 1- year followup. The relationship between age, sex, extent of injury, type of injury, ischemic time, regular smoking, level of injury, and survival rate were analyzed. There were 234 patients with 155 males (254 digits) and 79 females (129 digits). RESULTS: Successful operation was found in 203 patients (86.3%), 314 digits (82%). Although male patients seemed to have poorer survival rates than female, it should be noted that male patients had more severe injuries than female patients. All patients who were regular cigarette smokers were males. Cigarette smoking has been shown to cause cutaneous vasoconstriction, decrease the digital blood flow, and impair the wound healing. These two reasons might explain the lower survival rate in males than in females. Type of injury significantly affected the survival rate. The survival rate was very low in extensive crushed amputation (11.1% survival rate), followed by degloving (21.1% survival rate) and avulsion (64.7% survival rate) amputation. The level of injury also seemed to determine the survival rate as injury at Zone I (65% survival rate) resulted in a poor survival rate compared to the injury at Zone II, III, or IV (92%, 97.6%, or 90.9% survival rate). Ischemic time longer than 8 hours might lessen the survival rate. CONCLUSION: All patients who had successful replantation and revascularization were satisfied with the results even though they had rather poor hand movement. In single digital replantation, no patients needed reamputation, but all preferred to have their finger replanted than udergo a primary amputation. All could accommodate and adapt their injured digits to their work.

Since the initial description of allergic fungal sinusitis by Millar et al. in 1981, reported cases have been increasing. However, one case of allergic fungal sinusitis has been reported in Korea. The diagnosis can be established by demonstrating type I hypersensitivity reaction, nasal polyposis, characteristic CT scan, eosinophilic mucus without evidence of fungal invasion into sinus tissue, and a positive fungal stain or culture of sinus contents. The authors present a case which met the diagnostic criteria of allergic fungal sinusitis. This patient had nasal polyp and showed elevated level of total IgE, peripheral eosinophilia, positive MAST and strongly positive immediate skin reactivity to fungal antigens. On histologic examination, typical allergic mucin containing sheets of eosinophils, Charcot-Leyden crystals was found. Fungal hyphae were also found in the mucin content.

PURPOSE: To investigate the difference in blood loss between two injection methods, intravenous (IV) and intra-articular (IA) methods via drain tube. MATERIALS AND METHODS: A total of 183 patients who underwent total knee arthroplasty between October 2013 and March 2016 were included. The method of tranexamic acid (TXA) administration was intravenously injected before August 2015, and it was applied thereafter to the joint through a drainage tube post intra-articular suture. Our subjects were divided into the following groups: The intravenous unilateral (IVU), intravenous bilateral (IVB), intra-articular unilateral (IAU), and intra-articular bilateral (IAB) groups. Hemoglobin and hematocrit, drainage amount, transfusion frequency, mean transfusion volume, and blood loss, as well as complications were compared between the groups. RESULTS: Drainage amount was 558.08±296.29 ml in IVU, and 498.39±199.70 ml in IAU; there was less drainage in IAU than in IVU, but without significance (p=0.262). Moreover, the drainage amount was 1,110.39±396.23 ml in IVB and 827.14±282.47 ml in IAB, which was significantly lower in IAB (p=0.000). Transfusion frequency was 5 patients (10.0%) in IVU and 2 patients (4.5%) in IAU, but without significant difference (p=0.442). Moreover, the frequency was 16 patients (29.6%) in IVB and 1 patient (2.9%) in IAB, which was significantly lower in the IAB group (p=0.002). Mean transfusion volume was 44.80±144.71 ml in IVU and 21.80±106.86 ml in IAU, but without significant difference (p=0.389); the volume was 177.80±321.00 ml in IVB and 18.30±108.18 ml in IAB, with statistical significance (p=0.001). Blood loss was 1,318.70±724.20 ml in IVU and 963.28±454.03 ml in IAU, which was significantly lower in the IAU (p=0.006); blood loss was 1,837.40±699.70 ml in IVB, and 1,337.60±382.20 ml in IAB and it was significantly lower in IAB (p=0.000). Complications included deep vein thrombosis in one case in IVU. CONCLUSION: In TKA, IA injection of TXA significantly reduced blood loss compared with IV injection, especially in bilateral TKA.

Oxidative stress-induced neurodegeneration is one of several etiologies underlying neurodegenerative disease. In the present study, we investigated the functional role of histone methyltransferase G9a in oxidative stress-induced degeneration in human SH-SY5Y neuroblastoma cells. Cell viability significantly decreased on H2O2treatment; however, treatment with the G9a inhibitor BIX01294 partially attenuated this effect. The expression of neuron-specific genes also decreased in H2O2 -treated cells; however, it recovered on G9a inhibition. H2O2 -treated cells showed high levels of H3K9me2 (histone H3 demethylated at the lysine 9 residue), which is produced by G9a activation; BIX01294 treatment reduced aberrant activation of G9a.H3K9me2 occupancy of the RE-1 site in neuron-specific genes was significantly increased in H2O2 -treated cells, whereas it was decreased in BIX01294-treated cells. The differentiation of H2O2 -treated cells also recovered on G9a inhibition by BIX01294. Consistent results were observed when used another G9a inhibitor UCN0321. These results demonstrate that oxidative stress induces aberrant activation of G9a, which disturbs the expression of neuron-specific genes and progressively mediates neuronal cell death. Moreover, a G9a inhibitor can lessen aberrant G9a activity and prevent neuronal damage. G9a inhibition may therefore contribute to the prevention of oxidative stress-induced neurodegeneration.

PURPOSE: To perform comparative analysis between the results of internal fixation and hemiarthroplasty in unstable intertrochanteric fracture of osteoporotic bone. MATERIALS AND METHODS: From February 2003 to February 2006, 36 patients treated surgically for unstable intertrochanteric fractures were evaluated. The patient's age was older than 70 year old; the T-score of preoperative bone mineral density (BMD) was lower than -3.0; they were followed up for more than 1 year. The patient were divided into two groups. One group was treated with dynamic hip screw or proximal femoral nail (Group A, 23 cases), and the other group was treated with bipolar hemiarthroplasty (Group B, 13 cases). The two groups were compared in terms of hip joint function using Clawson classification and radiologically. RESULTS: Nonunion and fixation failure happened in 6 cases (26%) of gruop A. However, all patients in group B showed stable maintenance of implant. Recovery of hip joint function was found in 13 cases (43%) of group A, whereas 12 cases (93%) of group B recovered. CONCLUSION: Nonunion and failure of fixation happened more frequently in internal fixation than bipolar hemiarthroplasty, and the postoperative hip joint function was better in bipolar hemiarthroplasty than internal fixation. Therefore, bipolar hemiarthroplasty might be better operative treatment for unstable intertrochanteric fracture of osteoporotic bone.
