The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.

PURPOSE: The purpose of our study is to evaluate the diagnostic significance of clinical findings, WBC count, ESR, CRP, simple X-ray, ultrasonography and bone sanning in neonates. MATERIALS AND METHODS: From January 1995 to May 1998, we have experienced 14 cases of pyogenic osteomyelitis and pyogenic arthritis in neonates. The mean age of patients was 16.7 days and the involved sites were 6 cases of pyogenic arhtritis of hip, 5 cases of pyogenic arthritis of hip with proximal femur osteomyelitis, 2 cases of pyogenic arthritis of shoulder with proximal humerus osteomyelitis and 1 case of proximal tibia osteomyelitis. RESULTS: The most frequent clinical signs were local swelling and pseudoparalysis of involved extremity. Laboratory findings showed that elevated ESR was in 11/14 (79%), positive CRP in 6/8 (75%), leukocytosis in 6/14 cases (43%). Abnomal findings in simple X-ray was in 7/13 (54%), positive bone scanning findings in 3/8 (37.5%), positive ultrasonographic findings in 11/11 cases (100%). CONCLUSIONS: ITherefore we concluded that careful physical examination and ultrasonography were important for early diagnosis of bone or joint infection in neonates

Early MRI and arthroscopic findings were compared to evaluate the efficacy of the former for patients, who upon physical examination, were diagnosed with possihle acute ACL tears. MRI, taken between 1-21 days after injury, had to reveal complete ACL tears and arthroscopic surgery should have taken place 3-12 weeks after the injury for patients of this prospective study. Fifty such cases were initially catagorized according to five MRI patterns. Types I to V were separated by the following ACL tear characteristics: Enlarged and diffusely increased in signal, horizontally oriented, non-visualized, discontinuous and vertically oriented. The cases were then divided into two groups of arthroscopic findings; Group A included cases of complete ACL tearing and group B included those with intact or minimally torn ACLs. Of MRI types I through V, there were 31, 9, 5, 4, and I cases of each respectively. 37 cases resulted in complete ACL tears (21 type I, 6 type II, 5 type III, 4 type IV and 1 type V) and 13 cases were catagorized into group B, 10 of which had pattern type I and 3 of which had pattern type II. As result, types III, IV and V had a 100% Positive Predictive Value (PPV) whereas types I and II together had a 67% PPV vaiue. Division of the cases into the five pattern types in early MRI proved valuble for possible cases of acute ACL tears. MRI pattern types III, IV and V were correlated with definite complete ACL tears. However, caution must be taken for types I and II, the majority of the cases, for which there exists a significant possibility for misdiagnosis and consequently unnecessary arthroscopic surgery.

Local anesthesia for arthroscopic procedure of the knee is an increasinglv popular technique that avoids the use of general anesthesia and the associated risks of respiratory depression, aspiration, and postoperative sedation. Many authors, for example McGinty etc., Martin, Yoshiya etc., advocated local anesthesia as safe and efficient method for arthroscopic procedures of the knee. We performed arthoroscopy of the knee under local anesthesia on 150 patients for diagnostic and operative purposes between January l993 and December l996. The technique of local anesthesia that we used was that 20cc of 0.5%; bupivacaine with I:200,000 epinephrine was injected into superolateral portal of the knee joint and additional 10-20cc ot 1% lidocaine into the arthroscopic portals. Pnevmatic tourniquet wa, not applied in all cases. We analysed the 150 cases and the results were as follows; The diagnostic arthroscopy was performed in 50 cases and the operative arthroscopy was in 100 cases. The duration ot local anethesia was from 4 hours to 12 hours, with an average of 6 hours. In 35 cases arthroscopy was performed as outpatient procedure and average hospital stay excluding other problem was 5 days. No complication related to systemic toxicity by local anesthetics was observed. Conclusively arthroscopy of the knee under local anesthesia is safe and effective procedure to avoid the risks of general anesthesia but patients selection is very important.

This study assessed preoperative quality of life (QoL) of gastric cancer patients exposed to inconsistent illness information by pre-post-operative stage discordance. The impact of information-stressors on patients’ QoL was investigated to determine information processing as a potential target for QoL management. Early-stage gastric cancer (EsGC) and late-stage gastric cancer (LsGC) groups based on their final stage were categorized by the consistency of preoperative staging information that was being shared. Those with consistent preoperative staging information were rated as EsGC (n=1,420) and LsGC (n=153) controls. EsGC and LsGC patients with misdirected information about their LsGC and EsGC were categorized as EsGC/iLsGC (n=32) and LsGC/iEsGC (n=55), respectively. Preoperative QoL data was obtained using EORTC QLQ-C30 and -STO22. QoL outcomes of EsGC/iLsGC and LsGC/iEsGC were compared with those of the EsGC and LsGC controls. QoL outcomes of the EsGC/iLsGC group matched that of EsGC control, but were significantly better than those of LsGC control on multiple scales including global health status/QoL, physical/role/social-functioning, and ten symptom scales/items. On the other hand, QoL outcomes of LsGC/iEsGC group were significantly better than those of LsGC control on multiple scales (global health status/ QoL, physical/role-functioning, and nine symptom scales/items) while they roughly matched with those of EsGC control. Intensified information-stressors did not exacerbate QoL beyond the influence of the patients’ medical condition, while de-intensified information-stressor improved QoL. Fear of negatively impacting QoL should not prevent the sharing of stressful illness information. As the de-intensified information- stressor improves QoL, information processing is recommended as a potential target for QoL management in cancer patients.

Serum C-reactive protein(sCRP) is an acute-phase reactant that exhibiting negative correlation with serum albumin concentration. It was reported that sCRP is an independent predictor of survival in both hemodialysis and peritoneal dialysis patients, and an acute phase inflammation could be preceded by protein catabolism, hypoalbuminemia, anorexia and even atherosclerotic cardiovascular disease. We have evaluated serum biochemical parameters including albumin and prealbumin, Kt/Vurea, nPCR, SGA score, anthropometric parameters and diet history in 30 ESRD patients maintained on chronic hemodialysis subdivided by sCRP concentration. Upon comparing the two subgroups[high CRP group(sCRP >or= 0.4mg/dL), n=15 vs. normal CRP group (sCRP<0.4mg/dL), n=15], high CRP group showed significantly lower levels of hemoglobin(9.3+/- 0.7 vs. 9.8+/-0.6g/L, p<0.05), hematocrit(28.3+/-2.3 vs 29.8+/-1.696, p<0.05), creatinine(9.6+/-3.1 vs. 12.2+/-2.5mg/dL, p<0.05), prealbumin(20.9+/-5.0 vs. 25.8+/-6.4mg/dL, p< 0.05), SGA score(5.0+/-1.2 vs. 5.9+/-0.7, p<0.05), and percent of patients who have higher nPCR than protein intake(85.7 vs. 28.6%, p<0.05). Ferritin was significantly higher in high CRP group(503.1+/-205.7 vs. 323.3+/-186.6, p<0.05). There were no differences in age, sex, duration of hemodialysis, prevalence of diabetic nephropathy and cardiovascular disease, Kt/Vurea, nPCR, residual renal function, amount of protein intake and other nutritional parameters. In conclusion, there was higher probability of malnutrition, anemia and protein catabolism in hemo-dialysis patients with elevated sCRP concentration.

PURPOSE: Peritoneal recurrence is one of the most common patterns of recurrence after gastric cancer surgery and it has a poor prognosis despite all efforts. The aim of this study is to evaluate the prognostic impact of early postoperative intraperitoneal chemotherapy (EPIC) after surgery with curative intent for macroscopically serosa-invading gastric cancer patients. MATERIALS AND METHODS: The records of 245 patients under the age of 70 were reviewed. These patients were suffering from macroscopically seroa-invading gastric cancer and they underwent curative surgery from 1995 to 2004 at the Kyungpook National University Hospital, Daegu, Korea. The overall survival, gastric cancer-specific survival, complications, and patterns of recurrence were compared between the patients who were treated with EPIC and those who were not. RESULTS: EPIC was administered to 65 patients, and the remaining 180 patients did not receive this treatment. The 5-year overall and gastric cancer-specific survival rates for the EPIC group were 47.4% and 53.1%, respectively, and those for the non-EPIC group were 26.7% and 29.7%, respectively (p=0.012 for overall survival and p=0.011 for gastric cancer-specific survival). The rates of peritoneal recurrence for the EPIC group and the non-EPIC group were 18.5% and 32.2%, respectively (p=0.038). There were no significant differences in the morbidity or mortality between the two groups. Based on a multivariate analysis of the factors with prognostic significance in univariate analyses, EPIC, pathological lymph node metastasis, differentiation, and the extent of gastric resection were independent prognostic factors. CONCLUSION: The use of EPIC to treat gastric cancer patients with macroscopic serosal invasions resulted in better survival rate by reducing the risk of peritoneal recurrence.
