BACKGROUND: Recently, the molecular pathologic investigation for clonality in lymphomas has been introduced and has gained a role in the diagnosis of lymphomas. In fact, the clonality test using TCRGR phenomenon has been done by Southern blot analysis (SBA) and polymerase chain reaction (PCR) for molecular pathologic diagnosis of T cell lymphomas. However, it is difficult to perform SBA with paraffin embedded specimens or with samples of small skin biopsies. OBJECTIVE: We investigated the efficacy of PCR amplification of TCR gene in paraffin em-bedded cutaneous T cell lymphomas. METHODS: Iii this study, the clonality was assessed by polymerase chain reaction (PCR) analysis of T cell receptor gamma (TCR) gene from the DNA extracts obtained from paraffin em-bedded tissues (PET) of malignant T cells, B cell lymphomas, and benign cutaneous T cell proliferative disorders. Heteroduple-x-analyses were also performed to rule out the false positives. RESULTS: Among the total of 62 cases analyzed, monoclonality was observed in 4 out of 10 mycosis fungoides, 7 out of 9 cutaneous T cell lymphomas excluding mycosis fungoides, 1 out of 3 angiocentric lymphomas, 2 out of 2 lymphomatosis papulosis, 1 out of 7 large plaque parapsoriasis, and 1 out of 2 T cell lymphomas in other organs. No monoclonality was observed in 9 inflammatory cutaneous diseases, 5 small plaque parapsoriasis, 4 cutaneous B cell lymphomas, and 11 B cell lymphomas in lymph nodes. CONCLUSION: The results suggest that the PCR method and heteroduplex analysis used in this study were not only practical but also efficacious for the diagnosis of cutaneous T cell lymphomas using tissues embedded in paraffins.

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.

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.

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: 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.

OBJECTIVE: To investigate the incidence of actinomyces-like organisms in routine cervical smears of Korean women and to evaluate its association with the development of pelvic inflammatory disease (PID) in these women. METHODS: The results of cervical smears between 2011 and 2012 at a single university hospital were searched. If positive for actinomyces-like organisms, the medical record of the patient was searched and development of PID was followed. If the data were not available in the medical record, the patient was contacted by telephone. RESULTS: The incidence of actinomyces-like organisms in cervical smears was 0.26% (52/20,390). Forty-two women (80.8%) were intrauterine device (IUD) users: the copper-IUD in 25 women and the levonorgestrel-releasing intrauterine system in 13 women (type unknown in 4 women). The majority (71.4%, 30/42) of the IUD users maintained the IUD. Prophylactic antibiotics were prescribed to 12 women. Two continuous IUD users were later diagnosed with PID, but these cases were not pelvic actinomycosis. CONCLUSION: It would be a reasonable option to choose the expectant management for asymptomatic women who incidentally showed actinomyces-like organisms in their cervical smear.

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 AND OBJECTIVES: Kawasaki disease is an acute systemic vasculitis of which pathogenesis suspected is caused by immune dysregulation. The goal of this study is to evaluate the activation pattern of T helper cell type 1 (Th1) and T helper cell type 2 (Th2) in patients with Kawasaki disease. SUBJECTS AND METHODS: Prospective study of 60 patients (male 36, female 24) with diagnosis of Kawasaki disease were enrolled. One hundred and eighty blood samples from these patients were collected according to the different clinical stages {before initial intravenous immunoglobulin (IVIG), 5 days after initial IVIG, 2 months after initial IVIG}. The plasma level of Th1 cytokines; interferon-gamma (IFN-gamma) & interleukin (IL)-2 and Th2 cytokines; IL-4 & IL-10 were measured by enzyme-liked immunosorbent assay. RESULTS: In all patients, the plasma level of Th1 cytokines (IFN-gamma, IL-2) and Th2 cytokines (IL-4 and IL-10) were markedly elevated during the acute stage of Kawasaki disease. Since then, the plasma level of all these cytokines decreased significantly along with the process of clinical stages. Regardless of the existence of coronary artery lesion or no response to initial IVIG treatment, there were no significant differences between them. CONCLUSION: These data suggest that both Th1 and Th2 cells may be activated simultaneously during the acute stage of Kawasaki disease. Further studies are therefore required to establish the difference of activation pattern of T helper cells between Kawasaki disease and other inflammatory diseases.

Korean Journal of Pediatrics 2015;58(11):434-439
PURPOSE: Kawasaki disease involves acute febrile systemic vasculitis that can cause a variety of symptoms by affecting various organs. Here, we aimed to evaluate the prevalence, causes, and prognosis of sensorineural hearing loss (SNHL) occurring in children with Kawasaki disease. METHODS: Patients who were diagnosed with Kawasaki disease and received inpatient treatment in the Pediatrics Department at one of three university hospitals in Daegu city from February 2012 to September 2012 were enrolled in the study. The clinical features, hematological results, echocardiography results, audiometry results, and aspirin and salicylic acid serum levels of the patients were evaluated. RESULTS: Of the 59 children enrolled in the study, three showed mild bilateral SNHL on audiometry tests conducted after 48 hours of defervescence; these patients demonstrated normal patterns of recovery on follow-up tests 8 weeks later. Aspirin serum levels were significantly higher in the SNHL group after 48 hours of afebrile condition with high dose aspirin intake (P=0.034). However, no significant differences were found in other laboratory tests or for fever duration (P>0.05). Upon echocardiography, coronary artery abnormality was observed in 9 cases, but none of these patients showed hearing loss. CONCLUSION: The results indicate that SNHL in children with Kawasaki disease might occur during treatment of the acute phase; this SNHL usually involves mild bilateral hearing loss and recovers naturally. However, this study suggests that determination of the causes and clinical implications of hearing loss in Kawasaki disease requires long-term follow-up studies with more cases.
