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.

PURPOSE: The purpose of this study was to investigate the polymorphisms of the TNF-alpha promotor gene, its susceptibility to Kawasaki disease (KD) and to assess whether the TNF-alpha promotor gene polymorphism was related the risk of coronary artery lesions (CALs). METHODS: From January 2003 to January 2007, 51 children (30 boys and 21 girls) with KD and 48 children forming an age-matched control group were studied. DNA from the peripheral blood of all the children was sampled, and the DNA polymorphisms of the 5' flanking regions of the TNF-alpha promoter gene at position -308 [guanine (G) to adenine (A)] were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Then, the relationship between KD and the TNF-alpha promotor gene polymorphisms was evaluated. RESULTS: The A allele frequency of the -308 site of the TNF-alpha promotor gene was 17.6% (9/51) for children with KD and 6.8% (3/48) for the control group children, but this result was not statistically significant. Twenty-four patients experienced CALs within 60 days after the onset of symptoms. KD children with TNF-alpha -308 A allele had lower frequencies of CALs (12.5% versus 22.2%, P>0.05). CONCLUSIONS: The DNA polymorphism of the -308 site TNF-alpha gene was not associated with susceptibility to KD and a risk of CALs. Multicenter, large-scale randomized controlled trials are needed for further study.

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: Arteriovenous fistula at the wrist has remained the procedure of choice for long-term chronic hemod ialysis since its development by Brecia and Cimino in 1966. Thrombosis is the most common cause of early failure after arteriovenous fistula procedure, should be reconized preoperatively or intraoperatively, but no consensus exits regarding the ideal preoperative or intraoperative screening method for access surgery. We describe a simple intraoperative maneuver that can be used to detect proximal stenotic vein segments. METHODS: From September 1998 to September 1999, a total of 117 arteriovenous fistulas were performed for permanent hemodialysis in patients with chronic renal failure. Of them, a intraoperative evoked thrill test was performed in 61 patients (A group), in 56 patients (B group or control group) was not. RESULTS: Early failure rate (<30 days) was 12.5% in A group, 9.8% in B group or control group. In this study, the specificity and positive predictive value of the evoked thrill test was 100%, indicating that this maneuver is highly accurate in predicting early failure. CONCLUSION: Evoked thrill test is a simple and useful intraoperative method for improving the patency rate of autologous arteroiovenous fistula.
