당뇨병은 혈액 속에 포도당이 높아져 이에 따른 각종 합병증 때문에 심각한 후유증을 초래할 수 있는 질환이다. 이 중에서 신장 합병증은 중요한 당뇨병 합병증 가운데 하나이다. 당뇨병성 신증은 거의 모든 당뇨병환자에게서 나타난다. 당뇨병성 신증의 마지막은 신장 기능이 거의 다 망가져 혈액투석이나 복막투석을 받는 말기신부전 환자의 가장 흔한 원인이 바로 당뇨병이므로 당뇨병의 신장 합병증을 줄이는 것이 환자의 삶의 질과 직결되는 문제라 할 수 있다. 신장합병증은 초기에는 증상이 잘 나타나지 않아 항상 주의가 필요하다. 신장이 손상되기 시작하면 단백뇨가 계속 나오고 혈압이 오르며 빈혈이 발생하고 몸이 붓는다. 이런 현상은 포도당의 대사물질이 사구체에 쌓이기 때문이다. '사구체'란 신장 안에서 오줌을 거르는 일을 하는 모세혈관 조직으로 일단 손상되면 회복되지 않고 진행되며 이 상태를 그대로두면 결국 더 이상 신장에서 혈액의 노폐물을 걸러내지 못하는 만성 신부전증으로 진행하게 되는 것이다.

Background: Pneumonectomy for inflammatory lung disease has been of major concern because of its associated morbidity and mortality, particularly with respect to pleuropneumonectomy. The purpose of this study is to evaluate the surgical outcomes, and identify the risk factors contributing to postoperative complications in patients undergoing pleuropneumonectomy. Material and Method: Ninety-eight patients underwent pneumonectomy for benign inflammatory lung disease were retrospectively analyzed. Pleuropneumonectomy (Group A) was done in 48 patients and standard pneumonectomy (Group B) was done in 50 patients. Clinical characteristics, postoperative complications were examined and compared between 2 groups. In pleuropneumonectomy group, postoperative risk factors affecting morbidity were evaluated. Result: There was one in-hospital death. Twenty-three major postoperative complications occurred in 21 patients (21.4%). The common complications were empyema and bronchopieural fistula (BPF) in 8 (8.4%), re-exploration due to bleeding in 8. At least one postoperative complication occurred in 14 of 48 patients from Group A (29.2%) and in 7 of 50 patients from Group B (14%). In Group A, empyema and BPF encountered in 6 and re-exploration for bleeding in 6 were the most common complication. In univariate analysis, right pneumonectomy, completion pneumonectomy, large amount of blood loss (>1,000 mL), and intrapleural spillage were risk factors contributing to postoperative complications in Group A. In multivariate analysis, intrapleural contamination during operation was a risk factor of postoperative complication. Conclusion: The morbidity and mortality rates of pneumonectomy for chronic inflammatory lung disease are acceptably. However, we confirm that pleuropneumonectomy is a real technical challenge and a high-risk procedure and technically demanding. Meticulous surgical techniques are very important in preventing serious and potentially lethal complications.

고혈압과 당뇨병은 성인에서 흔히 볼 수 있는 만성 질환으로서 특히 두 가지 질환을 함께 가지고 있는 경우가 많다. 고혈압과 당뇨병은 둘 다 심장질환, 뇌혈관질환, 신장질환 및 망막질환의 위험 인자로서 조기에 합병증을 발생시켜 유병률과 사망률을 증가시킨다. 통계에 의하면 당뇨병을 가지고 있는 사람은 없는 사람에 비해서 두 배 이상 고혈압이 발생하고 당뇨병 환자의 1/3에서 결국 고혈압이 발생하는데 특히 50세 이전에는 여자보다 남자에서 많이 발생하며, 50세 이후에는 남자보다 여자에서 많이 발생한다. 또한 백인에서 보다 흑인에서 두 가지 병을 가지고 있는 경우가 두 배 이상 많으며 경제적으로 빈곤할 수록 많이 발생한다고 한다. 당뇨병 환자에서는 고혈압이 유병률이나 사망률을 증가시키는 가장 중요한 요인인데 그 이유는 고혈압의 합병증, 즉 관동맥질환, 뇌졸중, 말초혈관질환, 신장질환 등의 발생과 성인 시력장애의 가장 흔한 원인으로 인정되고 있기 때문이다. 또한 당뇨병 환자에서도 고혈압 발생이 두 배로 많은데 당뇨병의 유형 및 기간, 신장질환 유무, 연령, 성별 및 인종에 따라 관련이 있다고 한다. 두 가지 질병이 다 같이 유사한 합병증을 일으켜 표적 장기에 손상을 주므로 두 질환을 가지고 있으면 이러한 합병증의 발병을 더욱 앞당기게 된다.

Purpose : The purpose of this study was to examine the clinical courses and long-term outcomes of children with Allagille syndrome in Korea, and to evaluate the prognostic potentials of identified variables. Methods : We reviewed the clinical manifestations and outcomes of 30 children with Alagille syndrome, investigated from 1984 to 2006 until the end of this study (defined as death or last visit; mean follow-up : 5 years). Results : Cholestasis occurred in 100 percent, cardiovascular abnormalities in 83.3 percent, butterfly vertebrae in 30.0 percent, posterior embryotoxon in 43.3 percent, and a characteristic facial appearance in 100 percent. At study conclusion, of these 30 patients, eight had died (26.7 percent); six related to Alagille syndrome. Five patients died of a liver disease complication. Liver transplantation was carried out in five of the 30 patients (16.7 percent) and one of these died due to hyperacute rejection. At age two, cholestasis improved in 17 of the 30 patients. Those who had severe cholestasis at 2 years of age tended to have a complication, such as liver cirrhosis or liver transplantation, or to have died. Conclusion : Hepatic complications account for the most mortalities in patients with Alagille syndrome. Careful and complete assessments should be made in children who have cholestasis at 2 years of age. Further investigations of more cases are required.

Puroose: This study evaluated the late rectal complications in cervix cancer patients following treatment with external beam radiotherapy (EBRT) and high dose rate intracavitary radiation (HDR ICR). The factors affecting the risk of developing late rectal complications and its incidence were analyzed and discussed. Materials and Methods: The records of 105 patients with cervix cancer who were treated with radical radiotherapy using HDR ICR between July, 1995 and December, 2001 were retrospectively reviewed. The median dose of EBRT was 50.4Gy $(41.4{\sim}56.4 Gy)$ with a daily fraction size of 1.8Gy. A total of $5{\sim}7$ (median: 6) fractions of HDR ICR were given twice weekly with a fraction size of $4{\sim}5 Gy$ (median: 4Gy) to A point using an Ir (Iridium)-192 source. The median dose of ICR was 24 Gy $(20{\sim}35 Gy)$. During HDR ICR, the rectal dose was measured in vivo by a semiconductor dosimeter. The median follow-up period was 32 months, ranging from 5 to 84 months. Results: Of the 105 patients, 12 patients (11%) developed late rectal complications: 7 patients with grade 1 or 2, 4 patients with grade 3 and 1 patient with grade 4. Rectal bleeding was the most frequent chief complaint. The complications usually began to occur $5{\sim}32$ (median: 12) months after the completion of radiotherapy. Multivariate analysis revealed that the measured cumulative rectal BED over 115 Gy3 (Deq over 69 Gy) and the depth (D) of a 5 Gy isodose volume more than 50 mm were the independent predictors for late rectal complications. Conclusion: With evaluating the cumulative rectal BED and the depth of a 5 Gy isodose volume as predictors, we can individualize treatment planning to reduce the probability of late rectal complications.

Purpose: Although high-dose-rate intracavitary radiotherapy (HDR ICR) has been used in the treatment of cervical cancer, the potential for increased risk of late complication, most commonly in the rectum, is a major concern. We have previously reported on 136 patients treated with HDR brachytherapy between 1995 and 1999. The purpose of this study is to upgrade the previous data and confirm the correlation between late rectal complication and rectal dose in cervix cancer patients treated with HDR ICR. Materials and Methods: A retrospective analysis was peformed for 222 patients with cevix cancer who were treated for curative intent with external beam radiotherapy (EBRT) and HDR ICR from July 1995 to December 2001. The median dose of EBRT was 50.4 (30.6$\~$56.4) Gy with a daily fraction size 1.8 Gy. A total of six fractions of HDR ICR were given twice weekly with fraction size of 4 (3$\~$5.5) Gy to A point by Iridium-192 source. The rectal dose was calculated at the rectal reference point using the barium contrast criteria. in vivo measurement of the rectal dose was peformed with thermoluminescent dosimeter (TLD) during HDR ICR. The median follow-up period was 39 months, ranging from 6 to 90 months. Results: Twenty-one patients (9.5$\%$) experienced late rectal bleeding, from 3 to 44 months (median, 13 months) after the completion of RT. The calculated rectal doses were not different between the patients with rectal bleeding and those without, but the measured rectal doses were higher in the complicated patients. The differences of the measured ICR rectal fractional dose, ICR total rectal dose, and total rectal biologically equivalent dose (BED) were statistically significant. When the measured ICR total rectal dose was beyond 16 Gy, when the ratio of the measured rectal dose to A point dose was beyond 70$\%$, or when the measured rectal BED was over 110 Gy$_{3}$, a high possibility of late rectal complication was found. Conclusion: Late rectal complication was closely correlated with measured rectal dose by in vivo dosimetry using TLD during HDR ICR. If data from in vivo dosimetry shows any possibility of rectal bleeding, efforts should be made to reduce the rectal dose.

Cardiovascular disease (CVD) has been identified as one of the most important factors influencing the long-term prognosis of patients with chronic kidney disease (CKD). However, in pediatric CKD, the clinical importance of CVD tends to be overlooked due to the lack of typical manifestations of CVD in this population. The literature has identified several traditional risk factors of CVD that originate from CKD, including hypertension, diabetes mellitus, dyslipidemia and obesity, in addition to new and non-traditional risk factors including anemia, secondary hyperparathyroidism, oxidative stress and inflammation. In cases of pediatric CKD, cardiovascular disease is usually restricted to subclinical manifestations such as left ventricular hypertrophy, thickening of intimal media on the carotid artery and calcification of the coronary artery. Therefore, risk factors of CVD in pediatric CKD patients should be closely monitored.
