The purpose of this study was to provide quantitative data describing the effect of rapid palatal expansion (RPE) on nasal airway resistance (NAR). RPE is an orthopedic procedure which is commonly used to widen the maxilla in skeletal Class III patients. 18 subjects (9 males and 9 females, mean age: 10 years 7 months) were selected from the Orthodontics in Yongdong Severance Hospital. Recordings of NAR were taken by active anterior method prior to expansion, immediately after desired maximum expansion, and after approximately 3 months and 6 months, and 1 year. All data was recorded and statistically processed with the SPSS program of IBM PC system. The results are as followings: 1. The average initial NAR of the subjects was 3.84cm H2O/LPS (SD +/- 1.34). It was greater than the average NAR of the normal subjects. 2. Among 18 subjects, 9 subjects showed reduction of NAR and 9 subjects showed no specific change of NAR after expansion. 3. An average reduction in NAR after immediately expansion was statistically significant at the 0.05 level. 4. The reduction appeared stable throughout the post treatment observation period of 1 year after expansion. From these results, it was suggested that RPE is a useful method to reduce NAR.

The role of surgical wire in the bone and joint surgery is very important. To get a maximum effect of the surgical wiring, the orthopaedic surgeon should not only select appropriate wire diameter but also apply adequate wiring technique. When strong fixation is required, wire loops are frequently untrustworthy. These are due to insufficient caliber or inadequate technique of wire thightening and/or twisting. The theoretical background for effective wiring technique and useful diameter in cerclage wiring is poor. Ultimate stress and stress at breaking point of different diameter of the wire was higher in 16G than 18G or 21G. Twist knot was stronger than knot twist. Wire holder was more effect than tensioner(york). Tension tightening with twist knot by wire holder have been found most suitable for internal fixation by surgical wire.

Postoperative total blindness was seen in a 48 year old male who had a laparotomy for traumatic perforation of intestine. General inhalation anesthesia of ether-oxygen-mask with semiclosed system was applied after initial ketamine administration. This unhappy ocular complication could be occur secondary to excessive prolonged external compression to eyeballs with mask or/and prolonged postoperative hypotension.

Liposarcoma is one of the most common soft tissue sarcomas that occurs in adults and is currently divided into five main subgroups: well-differentiated, myxoid, round cell, pleomorphic, and dedifferentiated. Primary mesenteric liposarcoma is extremely rare, and the treatment strategy is surgical resection with a wide free margin, often followed by radiation and adjuvant chemotherapy if distant metastasis is not detected. A 73-year-old male patient presented with lower abdominal distension. Abdominal CT scan revealed a large homogeneously enhancing mass lesion abutting the sigmoid colon and urinary bladder. At laparotomy, the solid mass measured 28x26x12 cm in size, was well-demarcated, and originated from the mesentery of the middle ileum. It was removed along with some small intestine (ileocecal valve upper 50-150 cm) and ileal mesentery because of adhesion. Histologically, the tumor proved to be pleomorphic liposarcoma. The patient did not undergo any adjuvant treatment following surgery, but he remains disease free until 33 months after surgery. Herein, we report a case of pleomorphic liposarcoma arising from small bowel mesentery.

Fabry's disease is a rare, inborn error, sex-linked disorder of glycosphingolipid metabolism with death occurring from myocardial or renal involvement at 4th or 5th decades. The primary metabolic defect lies in the deficient tissue activity of the enzyme alpha-galactosidase A which results in progressive accumulation of the specific neutral glycosphingolipids, cerebroside dihexoside(CDH) and cerebroside triihexoside(CTH), within the lysosomes of endothelial, perithelial and smooth muscle cells of the cardiovascular and renal systems predominantly. Clinical manifestations are sequelae of the anatomic and physiologic alterations produced by the progressive deposition of glycosphingolipid in the tissues. We report the first case of successful renal transplantation in a patient with Fabry's disease in Korea. The patient was a 33-year-old male. Fabry's disease was confirmed by measurement of serum alpha- galactosidase level and renal biopsy. Biopsy finding showed lamellar inclusion bodies on electron microscopy. Galactosidase activity was also markedly decreased. He has been well for 49 months.

About 90% of primary gastrointestinal lymphomas originate from the B-cell and less than 10% from the T-cell. In respect of anatomical location, the stomach is the most common site of gastrointestinal lymphomas followed by the ileum, colon, and rectum. However, esophagus and duodenal lymphomas are infrequently involved. Primary T-cell lymphoma of the duodenum is not common and peripheral T-cell lymphoma of the duodenum is very rare. In Korea, there has been no case report of peripheral T-cell lymphoma which simultaneously involved the stomach and duodenum. In this report, we present a case of primary peripheral T-cell lymphoma of the duodenum and stomach. A 63-year-old man was hospitalized complaining of weight loss of 15 kg and dyspepsia for 2 months. Esophagogastroduodenoscopy showed a large annular infiltrative lesion in the descending portion of the duodenum. At the posterior side of the upper body of the stomach, an ill-defined, broad, flat, and infiltrative lesion was also noted. Microscopic examination of the biopsy specimen showed that atypical bizzare lymphocytes infiltrated the mucosa of the duodenum and stomach. The lymphocyte was positive for CD3, CD5 and negative for CD20, CD23, and CD56 by immunohistochemistry. We made a diagnosis of primary peripheral T-cell lymphoma of the stomach and duodenum. We report a case of peripheral T-cell lymphoma of the stomach and duodenum with a review of the literature.

The purpose of this study was to estimate the national prevalence of childhood asthma and other allergic diseases in Korea, and to determine potential risk factors for the diseases. Stratified random samples of 42,886 were selected from 34 elementary (6-12 yr olds) and 34 middle schools (12-15 yr olds) nationwide, and 38,955 were in the final analysis. The Korean-translated modified version of the International Study of Asthma and Allergies in Childhood questionnaire was used in this cross-sectional survey. Twelve-month prevalences of the symptoms of asthma, rhinoconjunctivitis, and flexural eczema were 8.7%, 10.5%, 7.3% in 6-12 yr olds, and 8.2%, 10.0%, 3.9% in 12-15 yr olds, respectively. For allergic conjunctivitis, food allergy, and drug allergy, the prevalences in 6-12 yr olds were 11.2%, 6.5%, and 1.5%, respectively. Asthma and flexural eczema decreased significantly with age. Other significant risk factors were also noted. For 6-12 yr-old asthma, adjusted odds ratio (aOR) of body mass index was 1.21 with 95% confidence interval (CI) 1.0-1.48, aOR of passive smoking was 1.37 with 95%CI 1.24-1.51, aOR of carpet use was 1.28 with 95%CI 1.10-1.49. For 6-12 yr-old eczema, aOR of affluence was 1.22 with 95%CI 1.07-1.39. The control of obesity and passive smoking would be the most important preventive measures of allergic diseases.

Cyclooxygenase (COX)-1 and -2 expressions in the incisional wound healing of mouse skin were determined by immunohistochemistry and Western blot analysis. By Western blotting, compared to normal skin, COX-2 activity was increased at days 1, 4, 8, and 12 and was maximal at 4 day after incisional wound of mouse skin whereas COX-1 was barely detectable. In normal skin, COX-1 immunostaining was observed among the basal cells of epidermis whereas COX-2 immunostaining was detected in the more differentiated, suprabasal keratinocytes. At 1~4 days after wound, COX-2 staining was particularly prominent in the inflammatory cells, and at day 8, many macrophage-like cells were stained positively. COX-2 immunoreactive fibroblast, macrophage-like cells, and newly formed vascular endothelial cells were increased in number at 12 days after incision. These data suggest that COX-2 is constitutively expressed, just as is COX-1, in epidermis and is associated with keratinocyte differentiation. In addition, these findings support the well-established role for COX-2, the prostaglandins that they generate, as mediators of inflammatory response.
