PURPOSE: To describe the appearance and average thickness of the internal anal sphincter with anal endosonography in healthy Korean adults. MATERIAL AND METHODS: 184 subjects(male: 96, female: 88) with no history of anorectal disease or surgery were studied with anal endosonography. The average thickness of internal sphincter was meas ured at the mid-anal canal. For the internal sphincter, which is often asymmetric, the thickness of each 4 part(12, 3, 6 and 9 o'clock direction) were measured in left lateral decubitus position. RESULTS: The anal wall was well visualized in 5 layers(mucosa, submucosa, internal anal sphincter, intersphincteric plane, external anal sphincter) with anal endosonography. The anal endosonogram showed the internal anal sphincter as a homogenous, well-defined, hypoechoic, circular band, and slightly asymmetric. The average thickness of the internal anal sphincter in the area of mid-anal portion was 2.0 0.3 mm(range: 1~3 mm). There was no sexual difference; however, a significant positive correlation with age was found in average thickness of the internal anal sphincter. The correlation with lean body mass was not found. CONCLUSION: The internal anal sphincter is well-visualized, best defined structure by anal endosonography. Average thickeness of the sphincter in Korean appeared to be the same as in the Western.

Purpose:
To report a case of diffuse large B-cell lymphoma of the conjunctival fornix.Case summary: A 49-year-old man visited our clinic with redness and foreign body sensation in the right inferior conjunctival fornix that had begun 20 days previously. The patient had no pain, no fever, weight loss, and no past history of chronic disease. On slit lamp biomicroscopic examination, a large, salmon-colored, raised, well-defined, mass was detected in the inferior bulbar and fornix conjunctiva. We performed excision biopsy. The soft tissue lesion was 17 × 5 × 4 mm in size. Microscopic examination identified an area of small, mature mononuclear lymphocytes and an area of lymphocytes, such as large lymphoblasts with divided nuclei and conspicuous nucleoli. On immunohistochemical staining, the diffuse large B-cell lymphoma areas were positive for CD20 and Bcl-6, negative for CD3, CD5, and CD23, and the Ki-67 positive rate was relatively high. Finally, the patient was diagnosed with diffuse large B-cell lymphoma accompanying mucosal-associated lymphoid tissue lymphoma. There were no findings suggestive of metastasis invasion from other organs. The patient underwent immunochemotherapy after excisional biopsy. No recurrence has occurred over 1-year follow-up.
Conclusions
Although rare, diffuse large B-cell lymphoma should be considered in the differential diagnosis of conjunctival lymphomatous lesions.

PURPOSE: The ultimate goals of wound management are to avoid infection and to achieve a functional and cosmetically cceptable scar. The authors intended to determine the infection rate, as well as the patients, and the wounds, characteristics, associated with wound infection and with suboptimal appearance after traumatic wound management. METHODS: This prospective study was performed from Dec. 2002 to Aug. 2003 at Ewha Womans University Mokdong Hospital. Structured data sheets were completed at the times of the patient's Emergency Department visit and the Out Patient Department (OPD) follow-ups. Infection was determined at the time of follow-up, and a cosmetic score was determined at the time of suture removal. A multivariate analysis was used to determine the adjusted odds ratio (OR) of infection. RESULT: Of the 401 patients enrolled, infection was developed in 43 patients (10.7%). The characteristics associated with wound infection on multivariate analysis were age (adjusted OR per years, 1.024; 95% CI=1.010 to 1.037) and bite wounds (adjusted OR 8.645; 95% CI=2.753 to 27.150). A wound location on the head was associated with a lower risk of infection (adjusted OR 0.294; 95% CI=0.150 to 0.563). Suboptimal wound appearance increased with infection (p<0.0001). CONCLUSION: Both the patients and the wound's characteristics have influence on the likelihood of infection in cases of traumatic wounds. We found that increasing age, and bite wounds were associated with high risk of infection. Wound on the head were associated with lower risk of infection. Education were provided to patients. Efforts are needed.

The fetus is an unstable subject for an isolated physiological and biochemical study. To study the fetus in a controlled and stable environment, a trial was done using 12 goat fetuses. Extrauterine incubation system was devised using an extracorporeal membrane oxygenation system. The system consisted of a venous reservoir with a servo-controlled roller pump and a membrane oxygenator. The extra-corporeal circuit and membrane oxygenator were primed with the maternal whole blood of 200 mL. Fetal umbilical cords was exposed by Cesarean section. Fetal umbilical arterial blood was drained via the drainage cannula. The drained blood was perfused to the oxygenator by the roller pump. The highly oxygenated and decarboxylated blood was returned to an umbilical vein via the perfusion catheter. The blood flow rate was controlled manually using a roller pump. Fetal heart rate, blood pressure, and electrocardiogram were continuously recorded. Gas analysis of drained and perfused bood was performed hourly. With this system, the fetuses were able to survive under fairly stable physiological condition for periods of up to 34 hr. The extrauterine incubation system used in this study could therefore be a encouraging future experimental model in researching the artificial placenta for premature fetuses.

PURPOSE: inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO Withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. METHODS: Between January, 1998 and August, 1999 we sudied 10 patients who had rebound pulmonary hypertension(RPH) after iNO withdrawal. We completed the iNO in these patween the first the second trial of the weaning process. We tried to discover the differences between the first and second weaning process. We measured NO concentration at the start and just before NO withdrawal and during the period of weaning process. Moreover, to identify the iNO effects during the weaning of the iNO, we counted the degree of the change of PaO2/FiO2and mean PAP/SAP beween initial and at half of the initial NO concentration. RESULTS: Second weaning had a longer duration weaning process(11+/-0 cersus 5+/- hours, P<0.05), lower NO concentration just before NO withdrawal(2+/-.6 versus 4+/-ppm, P<0.05). In the change of the mean PAP/SAP and PaO2/FiO2as iNO was weaning from the initial iNO concentration to a half of the initial iNO concentration, the degree of increase in mean PAP/SAP(0.026+/-.07 versus 0.054+/-.07, P<0.05) and the degree of decrease in PaO2/FiO2(49+/-4 versus 65+/-2, P<0.05) were smaller in the second in the second weaning process than the first weaning process. CONCLUSION: A successful weaning of iNO can be performed with a low iNO concentration at the start and just before withdrawal and with the long duration iNO weaning process. Moreover, We speculate that the degree of change in the mean PAP/SAP and PaO2/FiO2at the half of the iNO weaning process are an indicator for the development of RPH.

Tumor necrosis factor (TNF) -alpha plays a major role in the pathogenesis of Kawasaki disease (KD), a systemic vasculitis primarily affecting young children. We performed this study to examine the serum levels of TNF-alpha and to investigate a possible relation to promoter polymorphism at positions -238 and -308 in KD patients in Korea. We obtained 48 paired serum samples from 24 patients in the acute and subacute stages of KD, and control sera from 12 age-matched children who were having routine blood samples taken before elective surgical procedures. Our studies showed a significant increase in serum levels of TNF-alpha measured in the acute stage of KD (24.1+/-9.4 pg/mL) compared to those in the subacute stage (11.8+/-5.8 pg/mL; p < 0.01) and normal controls (10.4+/-4.9 pg/mL; p < 0.01). Previous studies report that the presence of the A allele at positions -308 and -238 may be associated with higher TNF-alpha levels. However, our results showed that the frequency of the A allele at position -308 in the KD patients was the same as the controls (2 out of 24, 8.3% vs. 8.3%, odds ratio (OR) = 1.00), while the frequency of the A allele at position -238 in the KD patients was lower than the controls (0/24, 0% vs. 8.3%, OR=0.00) ; this difference though was not statistically significant. We concluded that although TNF-alpha levels were significantly elevated in the acute stage of KD, there was no significant difference in the frequency of the A allele at positions -238 and -308 between the KD and control groups in Korean patients.
