Purpose:
We report on the 10-year clinical hip function and radiologic outcomes of patients who underwent hip arthroplasty using a COREN stem.
Materials and Methods:
A consecutive series of 224 primary cementless hip arthroplasty implantations were performed using a COREN stem between 2009 and 2011; among these, evaluation of 128 hips was performed during a minimum follow-up period of 10 years. The mean age of patients was 65.4 years (range, 40-82 years) and the mean duration of follow-up was 10.8 years (range, 10-12 years). Evaluation of clinical hip function and radiologic implant outcomes was performed according to clinical score, thigh pain, and radiologic analysis.
Results:
Dramatic improvement of the mean Harris hip score (HHS) from 59.4 preoperatively to 93.5 was observed at the final follow-up (P≤0.01). Stable fixation was demonstrated for all implants with no change in position except for one case of Vancouver type B2 periprosthetic femur fracture. A radiolucent line (RLL) was observed in 16 hips (12.5%). Thigh pain was observed in only two hips (1.6%) at the final follow-up. There were no cases of osteolysis around the stem. The survival rate for the COREN stem was 97.7%.
Conclusion
Good long-term survival with excellent clinical and radiological outcomes can be achieved using the COREN femoral stem regardless of Dorr type.

PURPOSE: The purpose of this study was to analyze the patterns of failure and survival outcome in patients with brain metastases who received whole-brain radiotherapy (WBRT) with hippocampal avoidance (HA) using simultaneous integrated boost (SIB) on metastatic brain tumors. MATERIALS AND METHODS: We retrospectively reviewed 42 patients treated with HA-WBRT for brain metastases. A total of 25 Gy for whole brain and 35-55 Gy for gross tumors were delivered with 10 fractionations. Local tumor and intracranial progression were defined as a recurrence or tumor progression in SIB field and any recurrence or tumor progression within whole brain, respectively. Progression in HA zone was defined as the recurrence within the area expanded 5 mm from HA zone. RESULTS: Median follow-up duration was 10.0 months (range, 4.1 to 56.4 months). Intracranial progression was observed in 13 patients (31.0%) and the median duration from the start of HA-WBRT to progression was 10.6 months (range, 0.9 to 33.0 months). Local tumor progression and new metastasis outside SIB field occurred in 10 patients (23.8%) and nine patients (21.4%), respectively. There was no isolated hippocampal metastasis, except only one patient (2.4%) with multiple metastases inside and outside HA zone simultaneously. Median survival time and intracranial progression-free survival rate at 1 year were 19.4 months (95% confidence interval [CI], 9.6 to 29.2) and 71.5%, respectively, and those for overall survival were 26.5 months (95% CI, 15.4 to 37.5) and 67.9%, respectively. CONCLUSION: HA-WBRT was associated with low risk of new metastasis in HA region in the patients with brain metastases. These findings would serve as useful guidance on applying HA-WBRT in clinical practice.

PURPOSE: Deep infection after hip and knee arthroplasty is a serious complication and is difficult to treat due to its toxicity. The aims of our study were to find out the differences of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) infection after hip and knee arthroplasty focusing on clinical course and laboratory findings. MATERIALS AND METHODS: We retrospectively reviewed 61 staphylococcal infection cases after hip and knee arthroplasty (MSSA in 25 patients, MRSA in 36 patients). Vital signs, laboratory tests, microbiology and clinical courses were analyzed. The average follow-up period was 3.8 years (range, 2 to 10.1 years). RESULTS: At initial visit, MRSA group showed significant higher erythrocyte sedimentation rate, C-reactive protein (CRP) and neutrophil percentage. The average duration for the normalization of CRP was longer in MRSA group (MRSA: 36.7+/-25.1 days, MSSA: 24.7+/-13.6 days; P=0.008). The mean interval between staging operation was longer in MRSA group (MRSA: mean 8.7 weeks [range, 6.4 to 21.4 weeks], MSSA: mean 6.8 weeks [range, 6 to 13.1 weeks]; P=0.012). MRSA group (13.9%) revealed higher recurrence rate than MSSA group (4%). Two patients (5.6%) from MRSA group expired by sepsis. One limb amputation (2.7%) was carried out in MRSA group. CONCLUSION: MRSA infection after arthroplasty showed more toxic serologic parameter and poorer prognosis. Aggressive treatment should be considered for MRSA infection following arthroplasty.

PURPOSE: To identify the effect of insufficient lymph node dissection (LND) on the survival of patients with pT2 gastric cancer. MATERIALS AND METHODS: A total of 340 patients (120 patients with insufficient LND and others with D2 LND) who underwent gastrectomy for pT2 gastric cancer between January 2008 and December 2010 were included. RESULTS: The incidence of preoperatively diagnosed early gastric cancer was higher and there were fewer metastatic lymph nodes (LNs) in the insufficient LND group than the D2 group, but there was no survival difference between two groups (p=0.365). Among the 89 patients with metastatic LNs after D2 LND, 13 patients (14.6%) had metastatic LNs at selected N2 stations (#10, 11, or 12a), but none of these patients were in the pN1 category. One patient had five metastatic LNs at station #11p with no metastatic LNs at any other stations. The number of metastatic LNs was identified as the only risk factor for LN metastasis at selected N2 stations by logistic regression. CONCLUSION: If a patient has pN0 or pN1 category after insufficient LND for pT2 gastric cancer, the surgery can be regarded as secure. However, for patients with pN2 or pN3 category, more careful examination is required.

Antiphospholipid antibody syndrome (APS) is defined as the presence of lupus anticoagulant antibody or anticardiolipin antibody with vascular thrombosis or pregnancy complications. APS can be associated with autoimmune disease or infectious disease. APS has also been reported in conjunction with variety of solid and hematologic malignancies. There were some reports on APS which were accompanied by hematologic malignancy, but there was no report with solid malignancy in Korea. We experienced one case of secondary APS, which was diagnosed during pre-operative evaluation of thyroid cancer. This patient had prolonged aPTT (activate partial thromboplastin time) and decreased coagulation factors which were regarded as hemophilia at first. Although the precise mechanism of the relationship between APS and cancer has not been proven thoroughly, APS can be accompanied by various malignancies. So proper screening and early detection of malignancies in APS patients are recommended.

OBJECTIVES: The purpose of this study was to evaluate the efficacy and safety of magnesium sulfate and ritodrine hydrochloride in the management of preterm labor. METHODS: This study was undertaken to assess the clinical efficacy & safety of magnesium sulfate and ritodrine hydrochloride on 120 patients admitted with preterm labor from Jul. 1, 1996 to Dec. 31, 1998. RESULTS: 1. The incidence of preterm labor was showed 6.0~7.7% of total number of delivery. 2. The risk factors of the preterm labor were premature rupture of membrane, severe preeclampsia, previous preterm delivery, twin pregnancy, placenta previa, fetal anomaly, incompetent cervix, placental abruption, and uterine myoma in order, but 28.6% of preterm labor had no apparent risk factors. 3. The days gained in uterus was not statistically different between the magnesium sulfate group and the ritodrine group (p<0.05) but longer in the two groups than the control group. And the delivery time was also not statistically different between the magnesium sulfate group and the ritodrine group (p<0.01) but significantly increased in the two groups than the control group. 4. The rate of complete and incomplete success was similar as 12.5% and 35% (total success rate 47.5%) in the magnesium sulfate group, 7.5% and 45% (total success rate 52.5%) in the ritodrine group but only 2.5% and 27.5% (total success rate 30%) was showed in the control group. 5. The side effects were much more in the ritodrine group than the magnesium sulfate group. The patients requiring second-line therapy were similar in the both groups but the main cause was uncontrolled uterine contraction in the magnesium sulfate group, and intolerable side effects in the ritodrine group. 6. The pulse rate was not statistically different in magnesium sulfate group but markedly increased in ritodrine group (p<0.05). After managements of preterm labor, the serum potassium and ionized calcium level was significantly decreased in the two groups (p<0.05, p<0.01). CONCLUSION: There was not significantly different efficacy and safety of magnesium sulfate and ritodrine hydrochloride in the management of preterm labor.
