We report a caae of hepatic and intestinal infestation with paragonimus wewstermani complicating abscess formation. The pathway by which the paragonimus westermani reaehea liver and intestine is not well understood. However, there was possiblity that it may become lodged in other organs that the lung because of polonged larval migrations through the diaphragm or into various sites in the abdomen. The patient, 52-year-old female gave a history of having reyeatedly consumed raw crabs. An x-ray film of the chest showed clear lunga Skin test for paragonimus-westermani was positive. Abdominal ultrasonogram showed enlargement of the liver with multiple hypoechoic lesiona ERCP revealed multiple ie lesions in the right lobe of the liver. Abdaminal CT showed multifocal abscess cavities with slight rim enhancements. Above meetioned diagnostic procedures suggested liver abscess or hepatoma. Then, an exploratory laparotomy was done for a definite diagnosis, Frozen biopsy, from liver and surgically exe mass from ileocecal region revealed extrpulmonary paragnomiasis involving liver and cecum. Thus, the patient was treated with prasiquantel. Three months later, abdominal ultrasonogram demonstrated slight enlargement of the liver but no evidence of abnormal mass like lesions.

STATEMENT OF PROBLEM: Many dental clinicians are concerned about immediate loading of inserted implants. However, there have been few clinical studies surveying the success rates of immediate loading, based on Korean implant systems. PURPOSE: The aim of this study was to evaluate the outcome of immediate functional loading of the implant (SinusQuick(TM) EB, Neobiotech Co., Seoul, Korea) in partially edentulous maxilla or mandible. MATERIAL AND METHODS: Total 15 implants were placed. Within 2 weeks after implant insertion, provisional implant-supported fixed partial dentures were delivered to the patients. Quantitatively, marginal bone loss was measured at the time of immediate loading, after 3-months of continued loading and at the last follow-up. The mean follow-up period was 4.8 months. RESULTS: Mean marginal bone loss from implant surgery to early loading, 3-months follow-up and last follow-up was 0.03 +/- 0.07 mm, 0.16 +/- 0.17 mm and 0.29 +/- 0.19 mm. No implant failed up to 6 months after insertion, resulting in a 100% survival rate. CONCLUSION: Immediate loading exhibited high success rate in partial edentulism for up to 6 months. Well-controlled long term clinical studies with large sample size are necessary to confirm this finding.

BACKGROUND AND OBJECTIVES: We checked traditional and high-level precordial electrocardiogram (ECG) leads in patients who had undergone right ventricular outlet obstruction (RVOT) reconstruction surgery and evaluated the effect of ECG lead position on their QRS duration. SUBJECTS AND METHODS: We enrolled 34 patients who had undergone surgery for congenital heart disease with RVOT obstruction and who had received followed up care that included recorded ECG at a pediatric cardiac out-patient clinic. The control group included 29 patients who did not have hemodynamically significant intracardiac abnormality. We recorded traditional standard 12-leads ECG from the 4th intercostals space, and moved the precordial leads to the 3rd and 2nd intercostals spaces, and recorded ECGs repeatedly. RESULTS: In all groups, there was no significant difference of mean QRS duration and QTc interval between traditional standard 12-leads ECGs and ECGs at higher intercostals spaces. There was no significant difference of ECG parameters between groups. In the control group, the degree of the change between the 4th intercostals space (ICS) QRS and 3rd ICS QRS was significant (p=0.031), and although, it was insignificant, ECGs at the 3rd ICS showed decreased QRS duration in group 1 (V1: 3rd ICS 119.21+/-21.53 msec vs. 4th ICS 122.80+/-31.78 msec. V2: 3rd ICS 113.68+/-19.43 msec vs. 4th ICS 118.24+/-19.16 msec). CONCLUSION: Although the positional change of ECG leads did not result in a significant effect on measuring QRS duration after surgery, ECG leads at the 3rd ICS rather than at the 4th ICS may cause alteration of ECG readings. Therefore, we suggest that ECGs should be recorded in as accurate a position as possible.

Plastic bronchitis is a rare disorder characterized by the formation of extensive, obstructing endobronchial casts. It is associated with asthma and complex cardiac defects such as those requiring the Fontan procedure. The treatment of plastic bronchitis comprises conventional therapy involving spontaneous expectoration and bronchoscopic removal and specific therapy with several new drugs. Herein, we describe the cases of 2 patients diagnosed with plastic bronchitis accompanied with a different underlying disease, which were treated with inhaled corticosteroid and low-dose oral clarithromycin.

PURPOSE: We evaluated the characteristics of patients with Kawasaki disease (KD) who presented with only fever and cervical lymphadenopathy on admission, and compared them with the characteristics of those who presented with typical features but no cervical lymphadenopathy. METHODS: We enrolled 98 patients diagnosed with KD. Thirteen patients had only fever and cervical lymphadenopathy on the day of admission (group 1), 31 had typical features with cervical lymphadenopathy (group 2), and 54 had typical features without cervical lymphadenopathy (group 3). RESULTS: The mean age (4.3+/-2.1 years) and duration of fever (7.5+/-3.6 days) before the first intravenous immunoglobulin (IVIG) administration were highest in group 1 (P=0.001). Moreover, this group showed higher white blood cell and neutrophil counts, and lower lymphocyte counts after the first IVIG administration as compared to the other groups (P=0.001, P=0.001, and P=0.003, respectively). Group 1 also had a longer duration of hospitalization and higher frequency of second-line treatment as compared to groups 2 and 3 (group 1 vs. group 2, P=0.000 and P=0.024; group 1 vs. group 3, P=0.000 and P=0.007). A coronary artery z score of >2.5 was frequently observed in group 1 than in group 3 (P=0.008). CONCLUSION: KD should be suspected in children who are unresponsive to antibiotics and have prolonged fever and cervical lymphadenopathy, which indicates that KD is associated with the likelihood of requiring second-line treatment and risk of developing coronary artery dilatation.

BACKGROUND: Endoscopic Ultrasonography(EUS), a combination of endoscopy and ultrasonography is one of the most useful tools for diagnosis of digestive system diseases. EUS is useful in staging the primary tumor invasion and regional lymph node metastasis because of its ability to image the gut wall and adjacent structures in unique detail. We performed a study preoperatively for assessing the accuracy and limitation of EUS in gastric carcinoma. METHODS: In 75 patients(Male 54, Female 21, Mean age 62.3 years) with a gastric carcinoma confirmed by endoscopic biopsy, we performed EUS preoperatively. The results were compared with the postoperative histopathologic staging. RESULTS: 1) In assessing the depth of tumor invasion, EUS accuracy on depth of invasion was 76.0% and overstaging and understaging were 14.7% and 9.3%, respectively. 2) In assessing the lymph node metastasis, the accuracy rate of EUS was 65.3%. A rate of false-positive diagnosis was 27.3%, and a rate of false-negative diagnosis was 24.5%.3) In assessing the incidence of lymph node metastasis for each T stage, the involve rate was 10.5% in pT1, 36.4% in pT2, 95.7% in pT3, 100% in pT4. CONCLUSIONS: EUS is the most accurate diagnostic methods presently available to determine tumor infiltration depth and lymph node metastasis.

Pediatric Allergy and Respiratory Disease 2010;20(1):17-22
PURPOSE: Despite the appropriate antibiotic therapy, some patients with pneumonia do not show a significant clinical improvement. One of the important factors associated with the aggravation of pneumonia is the inflammatory response of the patient. The use of intravenous immunoglobulin (IVIG) to regulate inflammation in severe pneumonia may be beneficial. We evaluated the therapeutic effect of IVIG as an add-on therapy in patients whose pneumonia did not respond to the initial antibiotic therapy. METHODS: This study was conducted from January 2006 to March 2009 on 14 patients admitted with pneumonia who showed persistent fever and progressive worsening of radiographic findings in spite of appropriate empirical antibiotic therapy. Immunoglobulin was administrated on the 3rd to 10th admission days (6th days on average). RESULTS: The median age was 67 months (range 16-102 months), and 8 were female. All children received ampicillin+sulbactam+macrolide, or cefotaxime+macrolide. Acute Mycoplasma infection occurred in 64% (9/14) of the patients. The collapse and/or consolidation of the lobe was found in 50% (7/14) of the patients on chest radiograph. After IVIG administration, all patients became afebrile within 24 hrs, and their C-reactive protein and radiographic findings showed a significant improvement in several days. CONCLUSION: Prompt IVIG therapy may be beneficial to patients with pneumonia who did not respond to the initial antibiotic therapy, especially when the use of corticosteroids is contraindicated.

PURPOSE: Either gated myocardial perfusion SPECT or attenuation corrected SPECT can be used to improve specificity in the diagnosis of coronary artery disease. We investigated in this study whether gating or attenuation correction improved diagnostic performance of rest/stress perfusion SPECT in patients having intermediate pre-test likelihood of coronary artery disease. MATERIALS AND METHODS: Sixty-eight patients underwent rest attenuation-corrected T1-20l/dipyridamole stress gated attenuation-corrected Tc-99m-MIBI SPECT using an ADAC vertex camera (M:F=29:39, aged 59+/-12 years, coronary artery stenosis> or =70%. one vessel: 13, two vessel: 18, three vessel: 8, normal: 29). Using a five-point scale, three physicians graded the post-test likelihood of coronary artery disease for each arterial territory (1 normal, 2: possibly normal 3:equivocal, 4: possibly abnormal, 5: abnormal). Sensitivity, specificity and area under receiver-operating-characteristic curves were compared for each operator between three METHODS: (A) non-attenuation-corrected SPECT; (B) gated SPECT added to (A); and (C) attenuation-corrected SPECT added to (B). RESULTS: When grade 3 was used as the criteria for coronary artery disease, no differences in sensitivity and specificity were found between the three methods for each operator Areas under receiver- operating-characteristic curves for diagnosis of coronary artery disease revealed no differences between each modality (p>005). CONCLUSION: In patients at intermediate risk of coronary artery disease, gated SPECT and attenuation-corrected SPECT did not improve diagnostic performance.

Journal of the Korean Pediatric Society 2002;45(2):208-213
PURPOSE: The major cause of cardiac dysfunction, after open heart surgery for congenital heart disease, is perioperative myocardial injury. Cardiac troponin I is found only within the myocardial cell, so it can be used as a biochemical marker of the myocardial injury. We performed this study to evaluate the worth of cardiac troponin I as a biochemical marker reflecting the extent of perioperative myocardial injury and recovery. METHODS: Thirty-four patients who had undergone elective open heart surgery of congenital heart disease(CHD) from April to July 2001 were enrolled in this study. We measured types of CHD, serial cardiac troponin I(baseline 1 day before operation, postoperative day 1, 2, 3, 7), duration of cardiopulmonary bypass(CPB), aortic cross clamping(ACC), intubation and postoperative hospital stay. RESULTS: Compared with the baseline before operation, there was a significant, increase of cardiac troponin I on the postoperative day 1 and a significant gradual decrease on the day 2, 3, 7. The levels of cardiac troponin I were the highest in the transposition of great artery(TGA) repair on the postoperative day 1 and high in the tetralogy of Fallot(TOF), atioventricular septal defect (AVSD), ventricular septal defect(VSD) and atrial septal defect(ASD) repair with decreasing sequence. The longer duration of CPB, ACC and intubation, the higher of cardiac troponin I, but there were no significant correlations between cardiac troponin I levels and duration of hospital stay. CONCLUSION: Because there was significant increases or decreases of cardiac troponin I according to the perioperative time and types of the congenital heart disease, it is a worthy biochemical marker which reflects the extent of perioperative myocardial injury and recovery after open heart surgery.
