BACKGROUND: Pain after upper abdominal surgery may cause shallow and rapid breathing, resulting in postoperative pulmonary complications. Intramuscular injection of narcotics may increase mortality and morbidity of pulmonary complications. Continuous epidural infusion of opioid with local anesthetic mixture may produce good analgesic action without hypoventilation and hypoxia. METHODS: Forty patients for upper abdominal surgery, chosen at random, were studied for postoperative pain relief. In grouop 1 (n=20), pain was managed by intramuscular injection with meperidine and in group 2 (n=20), it was managed by continuous thoracic epidural block with morphine and bupivacaine mixture. In both groups, pulmonary functions were assessed before operation, on the 1st postoperative day. the 2nd day and the 3rd day. RESULTS: In group 1 and 2, On the 1st postoperative day, FEV was 32.1% and 45.4% of the preoperative value, FVC was 31.9% and 42.4% and MEF was 34.4% and 46.7%, respectively(P<0.05). On the 2nd postoperative day, FEV was 38.6% and 54.8%(P<0.01), PEF was 31.7% and 42.5%, FVC was 37.1% and 49.8% and MEF was 43.2% and 59.6%(P<0.05). on the 3rd postoperative day, FEV was 46.3% and 68.7%, PEF was 38.7% and 54.4%, FVC was 43.8% and 63.1%(P<0.01) MEF was 56.1% and 69.7% of the preoperative value(P<0.05). CONCLUSIONS: As a result of pulmonary function test, we suggest that continuous epidural infusion of morphine with bupivacaine mixture will be an appropriate way of postoperative pain relief methods, with its potential effectiveness in aged, smoking, obese and debilitated patients with ventilatory dysfunction.

Peanut Hypersensitivity

BACKGROUND: Although urticaria is a common skin reaction pattern occuring at some time in the life of approximately 15% to 20% of the population, the exact prevalence of food-induced acute or chronic urticaria remains unknown. OBJECT: The purpose of this study was to determine the prevalence of specific food allergies in patients with urticaria and the potential utility of the skin prick test and CAP-RAST FEIA in the diagnosis of food allergy. METHODS: One hundred patients with urticaria were evaluated for food hypersensitivity by history, eosinophil count, IgE, skin prick test, CAP-RAST FEIA, and open food challenge test (OFCT). RESULTS: 1) The prevalence of specific food allergies in the study population was 35% in history and 8, 18 and 6% in prick, CAP-RAST FEIA and OFCT, respectively. 2) The frequent food allergens were milk, egg, peanut, and wheat. 3) There were no correlations between the duration of urticaria and prick test, CAP-RAST FEIA and OFCT results. 4) Serum IgE levels were correlated with the prick test and CAP-RAST FEIA results, but not the OFCT results. 5) According to the history, 35 patients with urticaria answered that their symptoms were related to food, and of the 35 patients, positive reactions to the prick test and CAP-RAST FEIA were observed in 6 and 10 patients, respectively. Among the other 65 patients who answered that there was no relation between urticaria and food, 2 patients reacted positively to the prick test and 8 patients showed positive result to CAP-RAST FEIA. CONCLUSION: In contrast to high prevalence of food history, the prevalence of food-induced allergic urticaria in Korean patients is only 6%. In contrast to the prick test, CAP-RAST FEIA provides a standardized measurement of food specific IgE antibodies, which may be more useful diagnostic test than prick test to diagnose food allergy in urticaria.

This study aimed to evaluate the effects of two ginsenoside Rb1 (G-Rb1) loaded films on oral wound healing. Two types of G-Rb1 films, G-Rb1 loaded carboxymethyl cellulose (GCMC) film and G-Rb1 loaded hyaluronic acid (GHA) film, were developed. A total of 36 Sprague-Dawley rats were divided into 3 groups: control, GCMC, and GHA. After wound formation on midpalate, the control group was left without treatment, whereas the experimental groups had films attached. The specimen was analyzed clinically and histologically after 7 and 21 days. For clinical analysis, the area of incompletely re-epithelialized wound was measured. For histological analysis, the distance between the margins of the wound (soft tissue gap) was measured and the percentage of the collagen-stained area on the specimen was calculated. In clinical and soft tissue gap analysis, the GCMC group presented improved healing compared to the GHA group and the control at day 7 (p < 0.05). And, both GCMC (9.74 ± 10.12%) and GHA groups (19.50 ± 14.47%) presented greater collagen-positive pixels compared to control (0.89 ± 1.60%) at day 7 (p < 0.05). However, there were no differences in these parameters among the groups on day 21. Therefore, G-Rb1 loaded films improved oral wound healing.

OBJECTIVES: This clinical study evaluated the effect of light activation on the whitening efficacy and safety of in-office bleaching system containing 15% hydrogen peroxide gel. MATERIALS AND METHODS: Thirty-three volunteers were randomly treated with (n = 17, experimental group) or without light activation (n = 16, control group), using Zoom2 white gel (15% H2O2, Discus Dental) for a total treatment time of 45 min. Visual and instrumental color measurements were obtained using Vitapan Classical shade guide and Shadepilot (DeguDent) at screening test, after bleaching, and 1 month and 3 month after bleaching. Data were analyzed using t-test, repeated measure ANOVA, and chi-squared test. RESULTS: Zoom2 white gel produced significant shade changes in both experimental and control group when pre-treatment shade was compared with that after bleaching. However, shade difference between two groups was not statistically significant (p > 0.05). Tooth shade relapse was not detected at 3 months after bleaching. The incidence of transient tooth sensitivity was 39.4%, with being no differences between two groups. CONCLUSIONS: The application of light activation with Zoom2 white gel system neither achieved additional whitening effects nor showed more detrimental influences.

BACKGROUDN: Docetaxel is a highly effective chemotherapeutic agent with proven efficacy for non-small cell lung cancer (NSCLC). However, myelosuppression can be a substantial concern when docetaxel is administered every 3 weeks. Weekly administration of low-dose docetaxel has demonstrated a comparable efficacy together with a distinct toxicity profile with reduced myelosuppression. We conducted a phase II study of weekly administration of docetaxel and cisplatin or carboplatin in patients with advanced NSCLC to evaluate efficacy and safety. METHODS: Twenty-nine patients with advanced or metastatic NSCLC who had not received prior treatment were enrolled in the study. The patients received intravenous infusions of docetaxel (35 mg/m2 on days 1, 8, 15) and cisplatin (75 mg/m2 on day 1) or carboplatin (AUC 6), followed by a week of rest. RESULTS: Twenty-six patients were assessable for efficacy and all patients were assessable for toxicity determination. The overall response rate of the regimen was 44.8%. The median survival was 11.3 months, and the 1-year survival rate was 37%. Of the hematologic toxicities, grade 3/4 neutropenia were observed in 12.6% of the patients, but there were no episodes of neutropenic fever. Non-hematologic toxicities were mild. CONCLUSIONS: With this weekly dosing regimen, although efficacy is comparable, myelosuppression is substantially less, and the overall tolerability profile is better than with dosing every 3 weeks.
