Background and Objectives: Tonsillectomy is one of the most common operative procedures performed in children by otolaryngologists. However, many surgeons demand excessive fasting from their patients for the fear of pulmonary aspiration and postoperative bleeding after surgery. This study was performed to investigate the effect of early feeding after tonsillectomy on acute postoperative pain, vomiting and postoperative bleeding in children.Subjects and Method Data were collected via retrospective medical chart review. A total of 121 patients under the age of 12, who underwent tonsillectomy along with adenoidectomy in our hospital, were included in this study. The patients were divided into two groups according to the time of first water or liquid intake and first diet, respectively. Operation time, anesthesia time, state of appetite at the beginning of a soft diet, degree of postoperative pain, the requirement of intravenous analgesics and incidence of vomiting during hospitalization and incidence of postoperative bleeding were compared. Results: There was no significant difference in the degree of pain, the requirement of intravenous analgesics, the incidence of vomiting or postoperative bleeding according to the time of first water or liquid intake. In addition, there was no difference in the degree of appetite and pain, the requirement of intravenous analgesics, incidence of vomiting or postoperative bleeding according to the time of first diet. Conclusion Initiating feeding as early as possible after tonsillectomy does not appear to increase acute postoperative pain, vomiting or postoperative bleeding.

BACKGROUND: Ethyl cyanoacrylate is used as a component of adhesives used in the industrial, domestic, and medical fields. It is known to cause mucosal irritation, contact dermatitis and respiratory discomfort. However, reports of combined occupational asthma and rhinitis are rare, especially in Korea. We report a case of occupational asthma and rhinitis suspected to be caused by exposure to ethyl cyanoacrylate. CASE REPORT: A 36-year-old woman presented with rhinorrhea, cough, dyspnea and chest discomfort after exposure to ethyl cyanoacrylate adhesive at an assembly area of a plastic products manufacturing company. Nasal endoscopy revealed watery rhinorrhea and hypertrophy of nasal turbinates, which were compatible with rhinitis. The methacholine provocation test showed a positive result. Daily variability of peak expiratory flow increased on work days, but decreased during non-work days. Based on these findings, we diagnosed this case as a combination of occupational asthma and rhinitis suspected to be caused by exposure to ethyl cyanoacrylate. CONCLUSION: There needs to be increased awareness regarding occupational asth-ma and rhinitis caused by exposure to ethyl cyanoacrylate.

BACKGROUND: Darbepoetin alfa is a new erythropoietic agent with a three fold longer terminal half-life than recombinant human erythropoietin (r- HuEPO). The aim of this randomized, open-label study is to determine whether darbepoetin alfa is as effective as r-HuEPO for the treatment of anemia in hemodialysis patients when administered at a reduced dosing frequency. METHODS: A total 74 Korean hemodialysis patients receiving r-HuEPO therapy by either the intravenous (IV) or subcutaneous (SC) route were randomized to continue r-HuEPO or to receive an equivalent dose of darbepoetin alfa at a reduced dosing frequency. Patients receiving r-HuEPO once weekly changed to once every other week darbepoetin alfa, and those receiving r-HuEPO two or three times weekly changed to once-weekly darbepoetin alfa. The initial dose of darbepoetin alfa was based on the r-HuEPO dose at the time of entry into the study, using a formula equating the peptide mass of the two molecules (200 IU r-HuEPO=1 microgram darbepoetin alfa). The doses of r-HuEPO and darbepoetin alfa were titrated to maintain hemoglobin concentrations within -1.0 to +1.5 g/dL of patients' baseline values and within a range of 8.0 to 13.0 g/ dL for up to 20 weeks (16-week dose-titration period followed by a 4-week evaluation period). The primary end point was change in hemoglobin level between baseline and the evaluation period. RESULTS: The mean change in hemoglobin from baseline to the evaluation period was similar in the darbepoetin alfa (-0.03+/-0.19 g/dL) and r-HuEPO (0.27+/-0.20 g/dL) groups, and the difference between the two treatments was -0.30 g/dL (95% CI, -0.84 to 0.23). This was not a statistically significant or clinically relevant difference, despite the reduced frequency of darbepoetin alfa administration. The safety profiles of darbepoetin alfa and r-HuEPO were similar. CONCLUSION: This study suggests that darbepoetin alfa maintains hemoglobin as effectively as r- HuEPO, but with reduced dose frequency.

BACKGROUND AND OBJECTIVES: The so-called 'stress-induced cardiomyopathy' or takotsubo cardiomyopathy, mimicking acute myocardial infarction (AMI), has recently been reported, particularly in Japan. We prospectively studied the clinical characteristics of, for the first time with a Korean series, this novel syndrome. SUBJECTS AND METHODS: Eighteen patients, fore filling the inclusion criteria, were entered onto the study. The criteria for inclusion were: 1) no previous history of cardiac disease, 2) acute onset, 3) a regional wall motion abnormality in the left ventriculogram, typically in the apical segment, and 4) no significant stenosis in the coronary angiogram. RESULTS: The events preceding the condition included: emotional stress (N=7), acute illness (N=5), non-cardiac surgery or medical procedure (N=4) and accident (N=2). Chest pain, dyspnea, or nausea/vomiting were initially noted in 12 cases (66%). Pulmonary edema was demonstrated in 10 (56%), and cardiogenic shock in 4 (23%) of the patients. The peak creatinine kinase MB fraction was 69+/-136 IU/L. A T wave inversion was noted in all patients, whereas, a Q wave was noted transiently in only 1. The average left ventricular ejection fraction (LVEF) was 38+/-8% on the initial echocardiograms. On the left ventriculograms, 15 patients showed akinetic wall motion, or aneurysmal dilatation in the apical wall, however, notably in 3 patients in the mid-ventricular wall. The coronary vasospasm provocation tests were negative in all 10 patients tested. An intravascular ultrasonography showed no infarct-related plaques in the 4 patients examined. On a follow-up echocardiogram, the average LVEF was improved to 51+/-8%, and regional wall motion was normalized after 30+/-29 days following onset. CONCLUSION: We report, for the first time in a series of Korean patients, on a novel stress-induced cardiomyopathy with transient regional wall motion abnormality, mimicking AMI. The precise etiology remains to be elucidated in further studies.

Actinomycosis is an oppoturnistic infection of actinomyces, which are relatively avirulent endogenous oral commensals. After trauma or infection, they breach the normally protective mucosal barriers to invade adjacent soft tissue structures. Lesions routinely contain other bacteria, the normal resident flora at the site of primary infection, which act synergistically with actinomyces species to provoke this unique infection, which range from an acute suppurative process to a chronic fibrotic process. According to epidemic studies about pelvic actinomycosis, it should be significantly related to IUD(intrauterine device). It is accounted that IUD cause chronic intrauterine infection, tissue injury and act as nucleus for parasitic infestation. Here we present a case of pelvic actinomycosis related to IUD with brief review of the concerned literature.

Inflammatory pseudotumor is a infrequent, benign tumor that affects at all ages and involves the lung, gastrointestinal tract, and salivary gland. They are the most common, isolated, primary lesion of the lung in children, and usually present as circumscribed, peripheral, parenchymal tumors or endobronchial tumors, which may be usually static or increase slowly in size without causing symptoms. Surgical excision is the treatment of choice because of the location and benign nature of this lesion. The prognosis after resection is excellent. Other therapeutic modalities include radiation and steroid therapy. We experienced two cases of inflammatory pseudotumor of the lung parenchyme and endobronchus. We report these cases with a review of literatures.

Hepatitis B virus(HBV) infection has been suggested as the etiologic agent in membranoproliferative glomerulonephritis(MPGN), but the mechanism by which HBV infection leads to MPGN in human has not been established. To localize the HBV antigen and HBV-DNA in the kidney tissue, we examined paraffin sections of kidney biopsies which were positive for HBsAg by immunohistochemical study from 13 HBV carriers with MPGN (HBV-MPGN). Polymerase chain reaction(PCR) and in situ PCR(ISP) were used for the HBV DNA amplification and localization in kidney tissues. Primers used in PCR and ISP were from the S, C, and X HBV-DNA regions. Immunohistochemical study showed HBsAg deposits on the mesangium and glomerular capillaries. Arteriolar deposits were also occasionally observed. PCR for the S, C, and X regions were positive in 11 patients(85%), 11 patients(85%), and 9 patients (69%), respectively. The PCR findings were further confirmed by direct sequencing of PCR products and the amplification of HSP70 gene as a control. ISP showed the amplified HBV-DNA at the glomeruli and renal tubules. For S region, ISP was positive in 7 patients. For C and X regions, ISP was positive in 8 patients, respectively. 5 patients showed the positive signals for both the glomeruli and tubules, while 4 patients were positive at the tubules only. These 4 patients seemed to have the longer disease durations when compared to the other 5 patients (52.8 months vs. 11.8 months), but it was not statistically significant. In conclusion, the detection and the localization of HBV antigen and DNA in renal tissues indicate the presence of the complete virion in the kidney. These results suggest that HBV may infect the kidneys of HBV carriers with MPGN.

Churg-Strauss syndrome(allergic granulomatosis and angiitis) is a distinct entity composed of fever, eosinophilia, systemic vasculitis of multiple organ systems, and pathologically eosinophilic infiltration, granuloma and necrotizing vasculitis. In most cases it develops in patients with asthma, and renal involvement is characteristically mild and acute renal failure is rare in contrast to other systemic vasculitides. We report an unusual case of Churg-Strauss syndrome manifested by acute renal failure as well as fever, rash, eosinophilia, and nonfixed pulmonary infiltrates in a patient without history of asthma but with that of allergic contact dermatitis. Renal biopsy revealed interstitial eosinophil infiltration, glomerular, vascular and perivascular granulomas containing giant cells. Fever, eosinophilia, and acute renal failure improved immediately after prednisolone 1mg/kg/day demonstrating good response to steroid as in previous reports.

Most cases of acute renal failure induced by rifampin are due to acute tubulointerstitial nephritis and usually resolve spontaneously after discontinuation of rifampin. But there were a few reports that rifampin could cause crescentic glomerulonephritis. We present a 67 year-old male patient who has suffered from pulmonary tuberculosis and taken antituberculosis drugs including rifampin. The medication was interrupted two times because of anorexia and nausea. Azotemia, lower extremity edema and palpable purpura on both legs developed after administering antituberculosis drugs for two months. We performed the skin and kidney biopsy. The skin biopsy showed necrotizing vasculitis and kidney biopsy showed crescentic IgA nephropathy. He was tentatively diagnosed as rifampin induced rapidly progressive glomerulonephritis and underlying Henoch-Sch nlein purpura. The antituberculosis regimen was switched excluding rifampin and prednisolone was administered orally. His renal function was improved slowly over 4 months.

21-year-old male was admitted for evaluation of a mass shadow on chest film. On chest computed tomography showed 5 cm sized homogeneous low density based on the second thoracic vertebral body in the posterior mediastinum. The patient had been performed thoracic sympathectomy 6 months before admission and oxidized cellulose was used for hemostasis at that operation Surgical resection was performed and microscopic result was foreign body granuloma caused by oxidized cellulose. Oxidized cellulose is an absorbable sterile mesh and used to control capillary or venous bleeding. Although the manufacturer recommends its removal after hemostasis is achieved, in clinical practice it is usually left in situ to reabsorb spontaneously, usually with no untoward effect.
