BACKGROUND AND OBJECTIVES: High-dose intravenous immunoglobulin (IVIG) (2 g/kg) is usually given in the treatment of Kawasaki disease (KD). According to the authors' experience, however, medium-dose immunoglobulin (1 g/kg) was also effective in the majority of patients. We performed a retrospective clinical study to validate effectiveness of the medium-dose regimen in treatment of KD. SUBJECTS AND METHODS: A total of 274 patients with KD who were treated with medium-dose immunoglobulin at Bundang Jesaeng General Hospital from July 1998 to October 2007 were enrolled. RESULTS: Medium-dose immunoglobulin was given once in 220 patients (group A; 80.3%) and twice or more in 54 patients (group B; 19.7%). Age and gender distributions, duration of fever before treatment, hemoglobin concentrations, and white blood cell and platelet counts did not differ significantly between the two groups (p>0.05). Concentrations of C-reactive protein, aspartate aminotransferase, alanine aminotransferase, and bilirubin were significantly higher in group B (p<0.005). Coronary arterial lesions (CAL) were found in 51 patients (23.2%) in group A and in 26 patients (48.1%) in group B during the acute stage, and in 14 patients (6.4%) in group A and in 11 patients (20.4%) in group B during the convalescent stage (p<0.005, respectively). A giant aneurysm was found in one patient in each group (0.5% in group A and 1.9% in group B; p<0.005) during the follow-up period. CONCLUSION: A single infusion of medium-dose immunoglobulin was effective in 80% of patients with KD. About 20% of patients required two or more infusions of medium-dose immunoglobulin, who had higher concentrations of C-reactive protein, aspartate aminotransferase, alanine aminotransferase and bilirubin. The authors think that the medium-dose regimen proffers an advantage over the high-dose regimen in view of cost-effectiveness.

BACKGROUND: Simvastatin belongs to the statin family, whose members have immunomodulatory activities. Ezetimibe have synergetic effects when co-administered with simvastatin. In several case reports, alopecia totalis and alopecia universalis were successfully treated with simvastatin/ezetimibe, suggesting that this combination could be a new efficient therapy for recalcitrant alopecia areata (AA). OBJECTIVE: To verify the efficacy of the simvastatin/ezetimibe combination therapy for recalcitrant AA and investigate the relationship between various treatment responses and prognostic factors. METHODS: This prospective open study was performed in patients with recalcitrant AA with the bald surface exceeding 75%. All patients took simvastatin (40 mg) and ezetimibe (10 mg) daily. The extent of hair regrowth expressed as percentage of the bald area was used to evaluate the effectiveness of the therapy. RESULTS: Of 14 enrolled patients, 4 patients (28.6%) were judged as responders showing regrowth of 30% to 80% after 3 months of treatment. The mean age of onset in non-responders was significantly lower than in responders. The total score of prognostic factors, calculated as a sum of factors related to poor prognosis, was much lower in responders than in non-responders. CONCLUSION: The remission rate in this study was unsatisfactory. However, since the recruited patients had not responded to any other treatments for AA, simvastatin/ezetimibe can still be considered as an alternative treatment for recalcitrant AA. The total scores of the prognostic factors were statistically different between responders and non-responders. These results can be used to predict the outcome of treatment with simvastatin/ezetimibe and anticipate prognosis.

BACKGROUND: Management of atopic dermatitis (AD) involves the regular use of emollients together with topical steroids or calcineurin inhibitors for acute flares. However, the long-term use of oral medications in young children may have certain limitations. Wet wrap dressing (WWD) is an interesting alternative therapy for the short-term control of severe or refractory flares, thus avoiding the use of systemic treatments. OBJECTIVE: This study aimed to compare the efficacy between WWD and topical steroid agents and to control and estimate the utility of WWD in pediatric AD. METHODS: A total of 40 patients with mild-to-severe AD (eczema area and severity index of ≥3) aged <13 years were included in this study. Twenty patients were treated with WWD using two layers of cotton bandages or garments (Tubifast™), and the remaining were applied with topical steroid agents without cotton bandages. Improvement in severity of atopic dermatitis was evaluated using the eczema area and severity index (EASI). Improvement in skin barrier dysfunction was evaluated by measuring the transepidermal water loss (TEWL). We compared the two groups after 1 week of treatment using analysis of covariance and t-test. Furthermore, we surveyed the study groups using a questionnaire to estimate the utility of WWD and its adverse effects as well as to evaluate subjective outcomes of WWD. RESULTS: There were significant reductions in the mean EASI (−6.3, 95% confidence interval [CI]: −7.5 to −5.1, p=0.013) and TEWL (−26.7, 95% CI: −31.2 to −22.3, p=0.002) after 1 week of WWD treatment compared with the mean EASI (−4.0, 95% CI: −5.2 to −2.9) and TEWL (−15.4, 95% CI: −19.8 to −10.9) of the control group. Results of patient self-assessment and scores in the visual analogue scale (VAS) for pruritus were improved in both groups, but the differences were not statistically significant. Usefulness of WWD as an alternative therapy for the conventional therapy was satisfactory. CONCLUSION: This study is meaningful in that it estimates both the subjective and objective efficacy of WWD. In view of these findings, WWD showed superior therapeutic effects than conventional steroid application in the treatment of AD in children, with good compliance of patients and parent-caregivers.

Background:
Although alopecia areata (AA) is usually diagnosed based on the patient’s clinical manifestations, histologic features are the key to establishing the correct diagnosis. Moreover, it is possible to know about the progression of AA through understanding the various histologic characteristics of AA. Many studies have reported a lot of literatures related to AA, but studies investigating the correlation between histologic features and prognosis have not yet been reported.
Objective:
This study aimed to establish the histologic features of AA in scalp biopsy specimens and sought to correlate between histopathologic features and clinical prognosis.
Methods:
The pathology archives of Kyung Hee University Hospital at Gang-dong were searched for AA in the diagnostic field from the period of 2006 to 2016. The biopsy specimens were sectioned by Tyler technique. A total of 464 patients were included in the analysis.
Results:
There were reduction of anagen hair count according to the severity of AA, and a higher percentage of telogen ratio and vellus hair counts were observed in the alopecia totalis and alopecia universalis. Total hair counts (9.9) including miniaturized hairs were decreased prominently at more than 5 years of current duration. There was a high ratio of peribulge lymphocytic infiltration (45%) in patients with ophiasis and acute diffuse type and those with total alopecia showed prominent small portions of follicular miniaturization (27%).
Conclusion
These histopathologic features mentioned above may shed light on the understanding of disease progression of AA, which have various clinical aspects. Using these histologic features, we will be able to predict the efficacy for therapy and prognosis of AA.

BACKGROUND: Clinic-based blood pressure measurements may lead to untoward results in the management of hypertension. Masked hypertension (MH) has been shown to be related to a poor prognosis due to its hidden nature. The purpose of this study is to present the clinical predictors of MH in elderly patients over 65 years with well-controlled clinic blood pressure (CBP) and to evaluate the gap, the 'mask effect' (negative white-coat effect), between CBP and home blood pressure (HBP). METHODS: The BPs of 1,019 treated hypertensive patients were measured by a doctor at an out-patient clinic and by patients themselves at home. Clinical parameters for MH were analyzed in 511 patients with well-controlled CBP (45.6% men, mean age 57.1+/-9.0 years). RESULTS: Among the patients over 65 years (n=113, 46.8% men, mean age 68.4+/-7.3 years) and with well-controlled CBP, the prevalence of MH was 26.5% (30 patients). In multivariate-adjusted analysis, the risk of MH increased with physical inactivity (odds ratio [OR], 2.942; 95% confidence interval [CI], 1.039-8.329; p=0.042), use of beta-blocker (OR, 4.242; 95% CI, 1.528-11.785; p=0.06) and systolic clinic BP (OR, 1.083; 95% CI, 0.017-1.154; p=0.013). Furthermore, HBP correlated well with CBP (r=0.329; p<0.001) and further with degree of ME (r=0.723; p<0.001). CONCLUSION: In looking for MH, it would be useful to carefully assess patients taking beta-blockers, having higher CBP, and who are physically inactive by using self-monitoring home or ambulatory BP monitoring.

BACKGROUND/AIMS: The aim of this study was to evaluate the diagnostic accuracy of 64-multidetector CT (MDCT) cholangiography for determining the causes of distal common bile duct (CBD) obstruction. METHODS: Two hundred fifty consecutive patients underwent 64-MDCT for diagnosing the clinical and biochemical signs of bile duct obstruction. The causes of bile duct obstruction were assessed by the pre- and post-enhanced axial and coronal multiplanar reformation images of 64-MDCT. The results were compared with ERCP, biopsy and surgery. RESULTS: The sensitivity and specificity of MDCT for CBD stones were 96.1% and 84.9%, respectively. In seven patients, The CBD stones in 7 patients could not be detected on MDCT. Eleven patients with stones in the distal CBD, as detected on MDCT, had no stones seen on ERCP. For malignant obstruction, the sensitivity and specificity of MDCT were 97.0% and 98.6%, respectively. Three patients who were diagnosed with periampullary cancers on MDCT were disclosed to have severe papillitis on ERCP. One patient who was diagnosed with CBD stone by MDCT was disclosed to have ampullary cancer. The overall accuracy of MDCT for determining the causes of biliary obstruction was 90.5%. CONCLUSIONS: MDCT cholangiography is a non-invasive method with relatively high sensitivity and high specificity for diagnosing the causes of distal CBD obstruction.

The esophagus or stomach can be perforated during diagnostic upper endoscopy in 0.03 to 0.1 percent. Instrumentation injury, as a whole, is probably the most common single cause of all cases of esophageal perforation. Most of the esophageal perforation result from either therapeutic maneuvers(dilation, sclerotherapy, foreign-body removal etc.) or underlying esophageal lesion(such as strictures or diverticular or neoplasm). Endoscopic perforation of the esophagus may be obvious immediately or within a few hours. Cervical pain, subcutaneous emphysema, fever, tachycardia, and characteristic radiographic appearances make the diagnosis easy, but some distal esophageal injuries are subtler, An immediate esophagogram should be obtained if peirforation is suspected. To select an appropriate course of management, precise delineation of location and the extent of perforation is necessary. The esophageal perforation can be managed conservatively by close observation, esophageal rest, and antibiotic coverage, but the mortality rate of medical treatment is near 12%. Causes of death are sepsis and multisystem organ failure. So we report a case of esophageal perforation by an endoscopic biopsy.

BACKGROUND/AIMS: In order to determine the malignant potential of gallbladder adenoma for progression to carcinoma, we evaluated the histopathologic features of adenoma and adenoma-related lesions on cholecystectomized specimens. METHODS: Among 1,847 cholecystectomized specimens, 63 specimens from 26 benign adenomas, 9 carcinomas in situ (CIS), and 28 invasive carcinomas were selected. A pathologist reviewed all specimens and selected benign adenomas, CIS in the adenoma, and adenoma residue in invasive carcinomas. Adenomas and adenoma-related lesions were classified according to morphology (tubular, tubulopapillary, and papillary) and the consisting epithelium (biliary, pyloric metaplasia, and intestinal metaplasia). The age and the size of the benign adenomas and carcinomas in the adenoma were also compared. RESULTS: Adenoma and adenoma-related lesions were found in 34 out (1.8%) of all resected gallbladder. Among 9 CIS and 28 invasive carcinomas, adenoma-related lesions were detected in 7 and 1 case, respectively. All eight carcinomas arising in the adenoma were well-differentiated solitary tumors. The diameters of the carcinomas in the adenoma were, on average, larger than that of the benign adenomas (1.8 cm vs. 0.9 cm, p=0.01). The patients with carcinomas in the adenoma were, on average, older than those with benign adenomas, although the difference was insignificant (57 years vs. 47 years, p=0.09). The morphology and consisting epithelium did not differ between the benign adenomas and carcinomas in the adenoma. The malignant transformation occurred in 23.5% of adenomas. CONCLUSIONS: Gallbladder adenoma is a rare disease, although malignant transformation occurs frequently. Adenoma is a precancerous lesion and the adenoma-carcinoma sequence is one of the gallbladder cancer carcinogenesis.
