PURPOSE: Present study has been undertaken to determine the distribution of various renal diseases causing asymptomatic hematuria in children and to evaluate the benefit of doing renal biopsy in these children. METHODS: Study population consisted of 146 children with asymptomatic primary hematuria who had been admitted to the pediatric department of Kyungpook National University Hospital for the past 4 years from 1999 to 2002. In 122 out of 146 cases, renal biopsy was performed percutaneously and in 24 out of 146 cases, diagnosed as idiopathic hypercalciuria, oral calcium loading test was performed. RESULTS: The age(mean+/-SD) at onset or discovery of hematuria of the 146 children included in this study was 8.0+/-3.2 years and the proportion of boys and girls was 54.8% and 45.2%, respectively. In 76 out of 146 cases(52%), asymptomatic hematuria was first diagnosed by school urinalysis screening. The proportion of histopathologic findings based on 122 biopsies was as follows : Thin Glomerular Basement Membrane(TGBM) 73 cases(50%); IgA nephropathy 20 cases(14%); Alport syndrome 6 cases(4%); Membranous Glomerulonephropathy(MGN) 4 cases(3%); Membranoproliferative Glomerulonephritis(MPGN) 2 cases(1%); IgA nephropathy with TGBM 3 cases(2%); "normal" glomeruli 14 cases(10%). Twenty four cases (16%) were diagnosed as idiopathic hypercalciuria. During follow-up periods, 15% of 146 cases became hematuria-free and renal function did not deteriorate in any cases. CONCLUSION: Unless hematuric children manifest poor prognostic indicators for renal survival, we would recommend long term regular follow-up prior to a renal biopsy.

Human papillomavirus(HPV) has implicated in the development of cervical cancer. Several studies has suggested a strong correlation between HPV 16, 18 and cervical intraepithelial neoplasia(CIN). For detecting and typing HPV DNA in cervical tissues, recently the chemiluminescent molecular hybridization assay method has been widely used. This study was performed to determine the usefulness of hybrid capture assay for detecting high-risk HPV in cervical epithelial cells, and to compare the correlation among cervical cytology, biopsy finding and HPV infection, and to determine whether the addition of the hybrid capture assay to cytologic test would improve the ability to identify significant lesions. This study included 267 patients who visited the colposcopic clinic of the department of obstetrics and gynecology, Chonbuk University Hospital from May, 1997 to October 199S. Pap smears hybrid capture assays, and colposcopically directed biopsy were performed concurrently on al1 women. The results obtained were as follow; l. Using hybrid capture assay, the detection rate of high-risk HPV of all patients was 37.1%(99/267). There was no statistical significance in the detection rate of HPV between the age groups. 2. The false negative rate of Pap Smear was 53.3% and showed significant discrepancies between the cytologic and histologic diagnosis. 3. According to the cytologic diagnosis, the detection rates of high-risk HPV were 7.1% in normal, 25.3% in ASCUS or LSIL, and 61.6% in HSIL. In each cytologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 4. According to the histologic diagnosis, the detection rates of high-risk HPV were 0.1% in normal, 11.1% in CIN I, and 72.7% in CIN II or CIN III. In each histologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 5. According to the comparison of histologic diagnosis between positive and negative results of high-risk HPV test due to each cytology, there was no statistical significance in the incidence rate of cervical neoplasia, Above results suggest that high-risk HPV test using hybrid capture assay may be a useful method in supplement the pitfalls of cervical cytology. This test might also have prognostic value in the management of patients with CIN.

PURPOSE: To evaluate the long-term therapeutic efficacy and durability of lamivudine in Korean children with chronic hepatitis B. METHODS: A total of 48 children (31 male and 17 female; age, 1~18 years, mean, 8 years) with chronic hepatitis B who received lamivudine for at least six months from March 1999 to September 2004 were followed for a mean period of 29 months (8~66 months) at Department of Pediatrics, Kyungpook National University Hospital in Korea. Response to treatment was defined as the normalization of ALT and HBV DNA levels, and HBeAg seroconversion after the initiation of treatment. RESULTS: Twenty nine (60%) among the 48 children treated with lamivudine responded and nine (19%) children lost HBsAg during therapy. ALT and HBV DNA level had normalized in 94% one year after the initiation of treatment. Kaplan-Meier estimates of cumulative HBeAg seroconversion rates over the years were 13% (0.5 year), 34% (1 year), 50% (1.5 years), 68% (2 years), 79% (2.5 years) and 90% at 3 years respectively. Above all, among the 22 children treated before the age of seven, loss of HBsAg occurred in eight (36%), which showed superior rate of HBsAg loss (p=0.002 vs age >7). CONCLUSION: Long-term treatment of lamivudine improved the rate of HBeAg seroconversion in Korean children with chronic hepatitis B. After three years' observation, most of treated children have sustained HBeAg clearance. We believe that lamivudine should be tried as the first therapeutic option for children with chronic hepatitis B in immune clearance phase.

OBJECTIVES: Family members are often cancer patients’ primary source of social and emotional support and make a major contribution to how well patients manage their illness. We compared the prevalence of depression in the family members of cancer patients and the general population. METHODS: This study used the data from the fourth, fifth, and sixth rounds of the Korea National Health and Nutrition Examination Survey. The variable of interest was the presence of a cohabitating cancer patient in the family and the dependent variable was the presence of diagnosed depression. RESULTS: The odds of having medically diagnosed depression in those with a cohabitating cancer patient in the family were significantly higher than among those who did not have cancer patients in their families (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.12 to 2.17; p=0.009). The OR for females was 1.59, and this increase was statistically significant (95% CI, 1.09 to 2.31; p=0.02). CONCLUSIONS: We need to invest more effort into diagnosing and managing depression in the family members of cancer patients. This will have an impact both on their quality of life and on the well-being of patients, as supporters and caregivers play an instrumental role in helping patients manage their illness.

BACKGROUND: Several kinds of stents have shown their safety and efficacy to treat acute or subacute closure after balloon angioplasty as well as to reduce restenosis rate. However, one of the limitations of stents is difficult to deploy especially in tortuos vessels, lesions at a bend, and distal to previously deployed stents. The Micro stent II, which was one of the most recently developed stents, ia a rapid-exchage balloon expandable stainless steel stent with a zigzag design connected with a continuous single weld in each 3mm segments. It scores over excellent trackability and optimum radio-opacity. Therefore, it is easy to operate and feasible in tortuous, distal lesions and variety of lesion lengths. We report our experiences with Micro-II stent implanatation in the first 76 patients at Tonsei cardiovascular center to assess its safety and efficacy in patients with complex coronary anatomy and clinical results in the first months. METHODS: Between January 1996 and July 1996, eighty-six Micro-II stent were implanted in the coronary arteries of 76 patients(male 65.8%, age 59+/-10 year). Forty-five patients had unstable angina, the others had stable angina(17pts), acute myocardial infarction(14pts). RESULTS: 1) Indication of stenting was de novo 51(59.3%), suboptimal result 25(29.1%), restenosis 1(1.2%) and 9(10.4%) of lesions were stented in bail out situation. 2) Single stent were implanted in 76(88.4%)lesions, overlapping stent in 10(11.6%)lesions. Among overlapping stents, the second stent with Micro-II stent and with another kind of stent were 4.6%, 7.0%, respectively. 3) Procedure related complication including a subacute closure was occurred in 1(1.2%) patient who had distal dissection and 45% residual stenosis. In 12(14%) lesions, preistent dissection has been noticed after stent impantation. 4) Angiographic success(defined as a residual stenosis of <30% without major dissection) was achieved in 82 of 86 attempts(95.3%). The procedual success rate(defined as a residual stenosis of <30% without occurrence of major clinical events within 4 weeks after procesure) was 96.1%(73/76 patients). Angiographic success and procedural success rate in calcified lesion were 100% and 100%, respectively. Angiographic success and procedural success rate in more than 45` angulated lesion were 97% and 100%, respectively. 5) The mean minimal luminal diameter of the target lesions was increased from 0.42+/-0.40mm before stent implantation to 2.93+/-0.50mm(p<0.001). The percentage of diameter stenosis was reduced from 86.49+/-13.04% to 1.40+/-7.11%(p<0.001) after stent implantation. CONCLUSION: Coronary stenting with AVE Micro-II stent can be safety performed and is particularly beneficial in tortuous and calcified arteries. There was a high tendency for peristent dissection which need to special consideration to avoid. Follow-up data is needed to assess mid and term patency. Coronary artery disease .

A radiation recall reaction refers to an inflammatory reaction at previous irradiated areas subsequent to the administration of a variety of pharmacological agents. The skin is the major site of radiation recall reactons with the muscle and internal organs being less commonly affected. These reactions usually occur days to weeks after exposure to the causative agents. We report a case of gemcitabine-induced radiation recall dermato-myositis the developed in a female patient with a metastatic non-small cell lung cancer. She had received a palliative radiation therapy of 3900 cGy to the metastatic lesion on the femur shaft prior to chemotherapy. The pain, swelling and erythema of the left thigh resolved after the cessation of gemcitabine and the use of a systemic steroid.

This study evaluated the possibility of the 3-dimensional attachment of human periodontal ligament fibroblasts to a periodntally involved root surface after an EDTA treatment in vitro. The human PDL fibroblasts were isolated from the middle third of the root of periodontally healthy teeth extracted for orthodontic reasons. The cells were cultured in a medium containing Dulbecco's modified Eagle medium supplemented with 10% fetal bovine serum at 37degrees C in humidified air containing 5% CO2. Eight single-rooted teeth were obtained from patients diagnosed with periodotitis. After scaling and root planing, four teeth were etched with 24% ethylenediaminetetracetic acid (EDTA) for two minutes (Experimental group). The other four teeth were not treated with EDTA and were used as the control group. The human PDL fibroblasts were placed in the total root surface and cultured for 4 weeks. The teeth were fixed in 2.5% glutaraldehyde in PBS before preparation for the scanning electron microscopy (SEM) examination. The human PDL fibroblasts showed a healthy morphology on the root surfaces treated with EDTA (Experimental group) and a relatively unhealthy appearance on the treated root surfaces (Control group). This suggests that EDTA favorably affects the 3-dimensional attachment of human PDL fibroblasts cultured on the root surfaces, which may play an important role in periodontal healing and regeneration.

Clinicians must be able to recognize post-extraction complications and treat them in a timely manner; complications that may potentially be life-threatening require special attention. Although arteriovenous malformation (AVM) is a very rare disorder, it may induce life-threatening hemorrhage during surgical intervention in the pertinent site. The present article examines the diagnosis and treatment modalities of AVM based on the case of a patient who was diagnosed with AVM with continuous bleeding after tooth extraction and who was successfully treated.
