This study is a clinical review of two groups of patients. Group I was composed of 97 patients who were submitted to negative appendectomy under the impression of acute appendicitis and, group II was 45 patients who received conservative treatment with the same impression at the department of surgery, Dae Rim Saint Mary's Hospital, from January 1, 1994 to August 31, 1996.The purpose of this study is to identify possible factors for the decision of operation or conservative treatment in the patients with suspected appendicitis and so to decrease unnecessary operation. Clinical characteristics of the patients were compared between two groups by the method of comparison of means(X test). The following results were obtained; 1) The incidences of group I and group II among the patients in the state of suspicious appendicitis were 97 of 1,004 cases(9.7%) and 45 of 1,004 cases(4.5%) respectively. 2) The number of female patients was 1.5 times more than male in both groups(p<0.05). 3) In group I the number of patients under 30 years of age was more than that of patients above 30 years of age(p<0.05) and in group II the highest incidence was shown in the patients in forth decades. 4) Symptoms over 3 days were more frequent in group I(31%) and in group II those within 12 hours were prominent(42.2%). 5) Gastrointestinal symptoms of anorexia, nausea and vomiting were more frequent in group I than group II. 6) Body temperature over 37.5 degrees C appeared in 15% of patients in group I and 11% in group II, but this difference showed no statistical significance and there was no sex difference. 7) RLQ rebound tenderness was manifested in 60% of patients in group I and 37.7% in group II, this difference has statistical significance(p<0.05). Migration pain to RLQ appeared in 12% of patients in group I aand 17.7% in group II(p>0.05) 8) Leukocytosis above 10,000/mm3 appeared in 44% of patients in group I and 53.3% in group II(p>0.05). 9) In admission route, the patients via ER was 2 times more than those of OPD in group I and in group II that was 5 times more than this.

BACKGROUND: We evaluated the role and effects of prolotherapy in patients presenting with lower back pain and detected sacral asymlocation, by retrospectively analyzing the results of prolotherapy performed at our institute. METHODS: Twenty-three patients with referred pain in the lower back rather than distinct radiculopathy, were detected to have sacral asymlocation by simple X-ray from May 2004 through July 2005. The patients were treated with prolotherapy and manipulation by the Ongley's method around the lumbosacral junction, iliolumbar ligament, and sacroiliac joint. They were treated for approximately one to two week intervals, and during this period were rechecked by X-ray and evaluated using the visual analogue scale (VAS). RESULTS: A total of 23 patients were included in the study (10 male and 13 female), and the average age was 41 years. The average VAS at the time of visit was 8.5, the average treatment time was 4.7 days, and the average VAS after treatment was 2.1. CONCLUSIONS: Back pain, and associated leg and buttock pain, originate from several causes. In these case analyses, instability around the lumbosacral area and sacral asymlocation might have been important causes of patient back pain and associated buttock and leg pain. We therefore applied prolotherapy as well as manipulation techniques devised by Ongley to these patients, and obtained good results.

OBJECTIVES: The purpose of this study was to evaluate the effect of adhesive luting on the fracture resistance of zirconia compared to that of a composite resin and a lithium disilicate glass ceramic. MATERIALS AND METHODS: The specimens (dimension: 2 mm × 2 mm × 25 mm) of the composite resin, lithium disilicate glass ceramic, and yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) were prepared. These were then divided into nine groups: three non-luting groups, three non-adhesive luting groups, and three adhesive luting groups, for each restorative material. In the non-luting groups, specimens were placed on the bovine tooth without any luting agents. In the non-adhesive luting groups, only zinc phosphate cement was used for luting the specimen to the bovine tooth. In the adhesive luting groups, specimens were pretreated, and the adhesive luting procedure was performed using a self-adhesive resin cement. For all the groups, a flexural test was performed using universal testing machine, in which the fracture resistance was measured by recording the force at which the specimen was fractured. RESULTS: The fracture resistance after adhesive luting increased by approximately 29% in the case of the composite resin, 26% in the case of the lithium disilicate glass ceramic, and only 2% in the case of Y-TZP as compared to non-adhesive luting. CONCLUSIONS: The fracture resistance of Y-TZP did not increased significantly after adhesive luting as compared to that of the composite resin and the lithium disilicate glass ceramic.

Although basic mechanisms of atopic dermatitis remain largely speculative, many studies on pathogenesis suggest the importance of food and inhalent allergens. To evaluate the frequency of food and house dust mite hypersensitivity and differences in this frequency according to ages, we measured the levels of specific IgE antibodies to egg white, egg yolk, milk, soy, and house dust mites in 119 children with atopic dermatitis. The results showed that 53% of patients had positive RAST to any one kind of allergens. The frequency of food and house dust mite hypersensitivity were 34.5%, 30.3 %, respectively. Among allergens, house dust mites and egg white are the most prevalent allergens in all atopic dermatitis patients. The Prevalence of egg white is most common under the age of 2 years, but those of house dust mites are the dust mites are the highest in the ages of 5-12 years. In conclusion, we recommend an egg restriction diet in atopic dermatitis patients who are less than 2 years old when their symptoms do not improve with general skin care.

PURPOSE: This study was to investigate how the crestal module design could affect the level of marginal bone stress around dental implant. MATERIALS AND METHODS: A submerged implant of 4.1 mm in diameter and 10 mm in length was selected as baseline model (Dentis Co., Daegu,Korea).A total of 5 experimental implants of different crestal modules were designed (Type I model : with microthread at the cervical 3 mm, Type II model : the same thread pattern as Type I but with a trans-gingival module, Type III model: the same thread pattern as the control model but with a trans-gingival module, Type IV model: one piece system with concave transgingival part, Type V model: equipped with beveled platform). Stress analysis was conducted with the use of axisy mmetric finite element modeling scheme. A force of 100 N was applied at 30 degrees from the implant axis. RESULTS: Stress analysis has shown no stress concentration around the marginal bone for the control model. As compared to the control model, the stress levels of 0.2 mm areas away from the recorded implant were slightly lower in Type I and Type IV models, but higher in Type II, Type III and Type V models. As compared to 15.09 MPa around for the control model, the stress levels were 14.78 MPa, 18.39 MPa, 21.11 MPa, 14.63 MPa, 17.88 MPa in the cases of Type I, II, III, IV and V models. CONCLUSION: From these results, the conclusion was drawn that the microthread and the concavity with either crestal or trans-gingival modules maybe used in standard size dental implants to reduce marginal bone stress.

Acute normovolemic hemodilution is widely used to conserve blood and to minimize the need for homologous blood transfusion during operation. To evaluate the effects of aeute isovolemic hemodilution on hemodynamics and oxygen transport, pulmonary artery catheter and radial artery catheter were introduced in 8 patients in whom maxillofacial or Wertheim's operation were performed. Blood(estimated from allowable blood loss) was withdrawn from radial artery, and simultaneously replaced by intravenous administration of 5% plasmanate and Hartmann solution. Acute isovolemic hemodilution decreased the hematocrit level from 33.2+/-3.7% to 29.6+/-2.9%. Cardiac output increased significantly, which was associated with decreased systemic vaacular resistance. Oxygen transport and oxygen consumption increased despite a decrease in oxygen carrying capacity. Heart rate, mean arterial perssure, mean pulmonary arterial pressure, central venous pressure, and pulmonary capillary wedge pressure did not change significantly during hemodilution. The results indicate that blood perfusion and oxygenation to tissue were well maintained in the hemodilution of the magnitude used in this study. Therfore it could be concluded that acute isovolemic hemodilution is a safe and relatively simple method of conserving blood and minimizing homologous blood transfusion.
