BACKGROUND: Esmolol is a short acting sympathetic beta receptor antagonist, and it was successfully applied to induced hypotension. Esmolol lowers blood pressure by decreasing cardiac output, and does not cause vasodilation. This property of esmolol may help to decrease bleeding during induced hypotension. In this study, we tried to elucidate the effect of esmolol on induced hypotension for total hip arthroplasty. METHOD: Twenty patients receiving total hip arthroplasty were randomly divided to two groups. Esmolol group (10 patients) received esmolol as a hypotensive agent, and sodium nitroprusside (SNP) group (10 patients) received SNP as a hypotensive agent. We measured arterial blood gas analysis, vital sign, amounts of bleeding, amounts of transfusion and administered fluid, and various laboratory findings. RESULTS: Induced hypotension was successfully performed in either esmolol and SNP group. Heart rate increased by SNP, and decreased by esmolol. There were no statistically significant differences between the two groups in amounts of bleeding, amounts of transfusion or administered fluid, and laboratory findings. Arterial oxygen tension was relatively constant in esmolol group, but decreased in SNP group. CONCLUSION: Esmolol can be used as a single hypotensive agent during induced hypotension without significant side effects during total hip arthroplasty.

Splenosis is the autotransplantation of fragmented splenic tissue that occurs as a result of traumatic splenic rupture or a routine splenectomy. Generally, splenic implants are numerous and located within the peritoneal cavity; peritoneum, omentum and abdominal viscera, and occasionally on extra-abdominal surfaces. Splenic implants are rarely clinically significant and are incidental found during an abdominal operation, but occasionally mimics primary or metastatic tumors, as seen on radiological studies. Herein, the case of a patient in whom multiple abdominal masses were identified as splenosis, but the initial radiographic finding was that of carcinomatosis peritonei.

A choriocarcinoma is a rapidly invasive, widely metastatic, human chorionic gonadotropin (HCG)-producing neoplasm, which are usually intrauterine and gestational. A primary gastric choriocarcinoma is very rare, and its pathogenesis is still uncertain. A 56-year old man presented with gastrointestinal bleeding and a gastric mass, clinically suspicious of a gastric adenocarcinoma. Thus, a radical subtotal gastrectomy and lymph node dissection, with a reconstruction, was performed. The resected specimen was found to be a Borrmann type I tumor, and a histological examination showed it to be a primary gastric choriocarcinoma, with an associated adenocarcinoma and a syncytiotrophoblast, which was immunostained by human chorionic gonadotropin (HCG). The serum HCG level, on the 7th postoperative day, was found to be 2, 775 mIU/ml. Chemotherapy was administered two months after surgery, as the patient refused chemotherapy during the immediate post operative period. At that time, the tumor rapidly recurred and disseminated to the liver. The patient died three months after the initial diagnosis.

PURPOSE: The present study assessed the diagnostic significance of digital infrared thermal imaging (DITI) in determining the inflammatory state of patients with nonspecific orbital inflammation. METHODS: The present study included 11 patients diagnosed with nonspecific orbital inflammation between December 2009 and March 2011 and who were followed-up for more than 6 months. All patients were all diagnosed based on computed tomography (CT), magnetic resonance image (MRI) and tissue biopsy. The grade of eyelid swelling was classified as 5 and severe compared with the temperature of location. The temperature of the upper eyelid, caruncle, medial conjunctiva, lateral conjunctiva, lower eyelid, cornea and lateral orbit were measured with DITI. RESULTS: When comparing the normal eye with the diseased eye in patients with nonspecific orbital inflammation, the temperature of the upper eyelid and cornea were statistically significant (p = 0.003, p = 0.038, respectively, Mann-Whitney test). The correlation between the grade of eyelid swelling and the temperature of location was most highly related in the temperature of the upper eyelid (Spearman's correlation coefficient, r = 0.55, p = 0.008) and cornea (Spearman's correlation coefficient, r = 0.45, p = 0.037). CONCLUSIONS: DITI may aid in evaluating the inflammatory state of nonspecific orbital inflammation. In particular, the temperature of the upper eyelid and cornea can be very useful indicator. Future studies, including larger study population are necessary in order to confirm DITI as a diagnostic tool which can assess the results of medical treatment by comparing temperature before and after treatment.

Objective:
The objective of this study is to assess the efficacy and safety of repeated sodium polynucleotide (Conjuran Ⓡ ) treatments in patients with knee osteoarthritis. Methods: The study was conducted by retrospectively examining 45 patients who repeated the treatment course of 5 injections of Conjuran Ⓡ twice within 6 months. For each course, pain reduction by the change of 100-mm Weight-Bearing-Pain Visual-Analog-Scale was compared with before administration until 6 months after administration. Improvement by Clinical Global Impression (CGI) and Patient Global Impression (PGI) were also investigated, as well as adverse reactions.
Results:
Pain analysis after administration of Conjuran Ⓡ confirmed that VAS decreased by 51.6% until 6 months (p<0.001), and after that the effect was lost and was repeat for the 2 nd course. In the 2 nd , VAS continued to decrease by 58.7% compared to before the 1 st course (p<0.001). Analysis of CGI, 88.9% of patients improved after the 1 st and 84.4% of patients improved after the 2 nd . In the PGI results, symptoms improved in 86.7% of patients after the 1 st and 82.2% after the 2 nd . No significant adverse event was reported.
Conclusion
The safety and efficacy results of patients receiving Conjuran Ⓡ for 2 nd treatment courses were similar to those for 1 st treatment course. In addition, the effect lasts for up to 6 months after administration, and the pain reduction effect is lost thereafter, so it is recommended to apply it at 6-month intervals if additional treatment is needed. Conjuran Ⓡ is an intra-articular injection that is effective in reducing knee pain and can be used repeatedly without adverse reactions.

BACKGROUND: The purpose of this study was to clarify whether the patients' age is an independent prognostic factor in curatively resected gastric adenocarcinoma. METHODS: Clinicopathologic information was reviewed for consecutive patients undergoing curative gastrectomy for gastric cancer during 6-year period (Jan. 1996-Dec. 2001) at the Keimyung University School of Medicine at Daegu. Overall survival was examined by the Kaplan-Meier method, and multivariate analysis by Cox proportional hazards was used to identify whether age had independent prognostic significance for survival. RESULTS: The patients were divided into two groups: 838 patients (72.4%) with age of less than 65 years old, and 320 patients (27.6%) with age more than 65 years old. In these two groups, there were statistically differences in WHO classification, Lauren classification, vascular invasion, T stage, total stage, operational morbidity and mortality, and overall survival rate. The 5-year overall survival rate of age less than 65 years old was 87.8%, and 83.0% of age more than 65 years old (p=0.019). Multivariate Cox regression analysis revealed that age was an independent prognostic factor to predict overall survival in curatively resected gastric cancer (p=0.038). However, after excluding cases who died within 1 month after gastric resection, overall survival rate was significantly different between two groups (p=0.050), but Cox regression analysis showed that age was not an independent prognostic factor (p=0.054). CONCLUSION: The age is not an independent prognostic factor in curatively resected gastric cancer patients, and survival differences are due to an increased operative mortality in elderly patients.

Journal of Gastric Cancer 2011;11(3):189-193
The natural course of untreated patients with signet ring cell carcinoma of the stomach remains poorly understood while assumptions have been made to distinguish it from other types of gastric cancer. A 74-year-old Korean woman was diagnosed with early gastric cancer with signet ring cell histology and refused surgery. A satellite lesion was identified 46 months after the initial diagnosis. The patient finally agreed to undergo distal subtotal gastrectomy 53 months following the initial diagnosis. Postoperative histological examination of both lesions confirmed signet ring cell carcinoma associated with submucosal invasion. There was no evidence of lymph node metastasis.

PURPOSE: To report the clinical results of a planned vitrectomy, laser photocoagulation and gas tamponade for the treatment of serous macular detachment associated with optic disc pit. However, laser photocoagulation was performed on a postoperative outpatient basis for subretinal fluid. CASE SUMMARY: A 13-year-old women presented with central visual disturbance in the left eye. Her best-corrected visual acuity (BCVA) was 0.16. On ophthalmic examination, the patient was diagnosed with optic disc pit combined with serous macular detachment. After 3 months, the serous macular detachment increased and visual acuity decreased to 0.1. Pars plana vitrectomy combined with complete posterior vitreous detachment was performed. After intravitreal injection of perfluorodecalin, internal drainage of the subretinal fluid using the back flush needle around the optic disc pit was performed, but the fluid was not drained. The planned intraoperative photocoagulation was not performed due to a large serous macular detachment. Gas tamponade was performed and a facedown position was maintained for 1 week followed by laser photocoagulation. The subretinal fluid was completely absorbed and visual acuity was improved. In addition, recurrence was not observed throughout the follow-up period.
