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.

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.

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.

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.

We report a case of posttraumatic intestinal stenosis (PIS), an uncommon sequela of blunt abdominal trauma, in which injury to the mesentery and bowel wall results in later focal ischemic stricture of that segment. We present CT images at the time of trauma and 3 weeks later when clinical signs of intestinal obstruction occurred. At surgery, a stenotic small bowel loop was found adjacent to a healed defect in the mesentery. Histologic examination of the resected segment showed mucosal and submucosal ischemia with mucosal ulceration, mural inflammation, and fibrosis. PIS subsequent to a mesenteric tear should be included in the differential diagnosis for a patient with a history of blunt abdominal trauma and signs of intestinal obstruction.

Several reports have described the usefulness of tumor markers detected in pancreatic juice for diagnosis of pancreatic cancer. We performed this study to evaluate the usefulness of tumor markers in pure pancreatic juice collected by duodenoscopic cannulation of pancreatic duct before and after injection of secretin. From April 1993 to July 1995, 8 cases of pancreatic cancer, 5 cases of benign pancreatic lesions, and 5 cases of benign biliary diseases without pancreatic lesion were involved. CEA and CA 19-9 immunoreactivity were measured by radioimmunoassay. Concentrations of CA 19-9 in pure pancreatic juice were significantly higher in patients with pancreatic cancer(median value; 3582, range 88.4-10410 IU/ml) than in control patients(median value 231, range 30.4-682 IU/ml)(p<0.05). Concentrations of CEA in pure pancreatic juice were not significantly different between patients with pancreatic cancer(median value: 6,5, range 1.0-152ng/ml) and control patients(median value: 4.0, range 1-17.2 ng/ml)(p>0.05). There was no significant correlation between levels of CA19-9, CEA in pancreatic juice and those levels in serum. The amounts of juice collected by duodenoscopic cannulation in patients with pancreatic cancer were 1.5+/- 0.9ml during 5 minutes before infusion of secretin, 11.3+/- 3.9ml, 10.8+/- 4.0ml, 10.6+/- 4.0ml in 5 minute interval after infusion of secretin. These results indicated that measurement of CA19-9 in pure pancreatic juice may be used as a marker for pancreatic cancer. Adequate amount of pancreatic juice was collected by duodenoscopic cannulation for evaluation of tumor marker, enzyme studies and cytology.

Journal of the Korean Surgical Society 2003;65(3):210-216
PURPOSE: Despite radical lymph node dissections and combined resections, experiences of recurrent gastric carcinomas are not infrequent. The prognosis of a recurrent gastric carcinoma has not improved despite the considerable recent progress in their treatment. This study was designed to investigate the correlation between the clinicopathological characteristics and recurrence patterns in gastric cancer following a curative resection. METHODS: The medical records of 1, 163 patients, who had undergone curative resection for primary gastric cancer, in Department of Surgery, Keimyung University School of Medicine, between January 1990 and December 1996, were retrospectively reviewed. The clinicopathological characteristics, relationship of each factor with the pattern of recurrence and the rate of recurrence were analyzed. RESULTS: Recurrent gastric cancer was confirmed in 350 patients (30.09%). The mean time interval to recurrence was 20.41+/-15.94 months. Of the patients with a recurrence, 231 (66.0%), 109 (31.1%) and 10 (2.9%) were early (0~2 years), intermediate (2~5 years) and late (more than 5 years) recurrences, respectively. 180 (51.4%), 90 (25.7%), 51 (14.6%) and 29 (8.3%) were peritoneal, loco-regional, distant and mixed recurrences, respectively. The recurrence patterns after a curative resection for a gastric carcinoma were related to the tumor location, differentiation, N-category and TNM stage. In a multivariate analysis, the size of tumor, Borrmann's classification, T-category, N-category, vascular invasion and Stage were found to be independent prognostic factors for a recurrence. CONCLUSION: Most recurrences of gastric carcinomas, following a curative resection, were found within 24 months. Therefore, the close follow up, with clinicopathological factors, is very important during this period, and might facilitate the early detection of a recurrence.
