Sporadic reports of hypernatremic dehydration in breastfed newborn infants have appeared in medical literature for at least 3 decades. We report the first case of hypernatremic dehydration resulting from inadequate breast-feeding in Korea. A 14-day old baby, born to a mentally retarded mother, was transferred to our hospital with a body weight loss of 460 g since birth(17%) and a serum sodium(Na) level of 179 mEq/L, after initial hydration at another hospital. On admission, a cardiac murmur was heard and an enlarged liver was palpated. Cardiac ultrasonogram revealed ventricular septal defect and ostium secundum atrial septal defect. During hydration, a seizure-like attack developed. Serum Na decreased to 135 mEq/L on the 5th day of admission. Brain ultrasonography and brain magnetic resonance image revealed no remarkable abnormalities. Electroencephalography was normal. She suffered from prerenal azotemia, hyperglycemia and disseminated intravascular coagulation at admission but was treated successfully. Heart failure was also controlled with dobutamine, diuretics and digoxin.

Hughes-Stovin Syndrome is an exceedingly rare combination of distal pulmonary arterial aneurysm and deep vein thrombosis, mostly found in young patients. There are striking similarities between the vascular manifestation of Behçet's disease and Hughes-Stovin Syndrome. It has been suggested that they may have a similar pathogenesis. Most patients died of massive hemoptysis due to rupture of aneurysm. Recently we have experienced the first case of Hughes-Stovin Syndrome in Korea. A 37 year old male patient was admitted because of recurrent hemoptysis and intermittent fever. He had a history of recurrent aphthous ulcers and erythema nodosum-like skin rash, But no other findings of Behcet's disease was found. Angiography showed multiple pulmonary arterial aneurysm and deep vein thrombosis in Right lower extremity. Histologic examination of specimens of open lung biopsy revealed leukocytoclastic angiitis. Pulmonary arterial aneurysms were successfully treated by coil embolization and he is in good condition with corticosteroid and cyclophosphamide therapy.

Percutaneous vertebroplasty consists of the percutaneous injection of polymethylmethacrylate (PMMA) cement into a collapsed vertebral body in order to obtain pain relief and mechanically strengthen the vertebral body. This procedure is now extensively used in treating osteoporotic vertebral compression fracture. It is an efficient treatment, but it is not free of complications. Most complications after vertebroplasty are associated with PMMA leakage. Pulmonary embolism of PMMA is rare, but this can occur when there is a failure to recognize venous migration of cement early during the procedure. We encountered a case of a patient with asymptomatic pulmonary embolism because of PMMA after percutaneous vertebroplasty. Chest X-ray and CT scanning revealed numerous tubular branching opacities that corresponded to the pulmonary vessels at the segmental and subsegmental levels.

일시적 혹은 단기간의 심폐보조는 여러 형태의 심부전에서 널리 이용되어 왔다. 이 중 체외막산소화장치는 고식적 치료에 반응없는 환자에서 주로 사용되는데, 소아에서는 자주 이용되어 왔으나 성인에서는 그 적응증이 명확하지 않았으며 결과도 만족스럽지 못했다. 환자는 승모판 협착증을 가진 32세의 여자로 제왕절개술후 발생한 폐부종으로 내원하였다. 내원시 환자는 쇽상태로 강심제, 폐혈관확장제, 이뇨제등에 반응이 없었다. 우측 대퇴정-동맥캐뉼라를 통하여 14시간동안 체외막산소화장치를 이용하였으며, 환자상태는 가동 즉시 호전을 보였다. 이후 양측판막치환술을 시행하였고 수술 후에도 체외막산호화장치를 지속하였다. 체외막산호화장치는 수술시간을 포함하여 모두 62시간동안 가동하였으며, 이탈(weaning)은 안정된 혈류역학, 호전된 폐부종, 기저질환의 교정등을 통하여 성공적으로 이루어졌다. 환자는 판막수술 후 30일째 특별한 합병증없이 퇴원하였다.

Various anomalous origins of the vertebral arteries (VAs) have been reported. However, anomalous origins of the bilateral VAs arising directly from the aortic arch are extremely rare. We encountered a 60-year-old male who developed sudden-onset right hemiparesis with an incidentally discovered rare origins of the bilateral VAs from aortic arch. CT angiography demonstratedt he right VA originating from the aortic arch distal to the left subclavian artery and left VA originating from the aortic arch between the left common carotid artery and the left subclavian artery. The possible embryological mechanism of this variant was also reviewed. If the VA can not be found in the usual position during the procedure, a rare variant of the VA with anomalous origin should be considered. Understanding these variations is important to avoid unexpected events during endovascular procedures or surgery.

Purpose : The aim of this study is to look for the possible efficacy of postoperative external irradiation for incompletely resected meningiomas. Methods and Materials : From August 198: to January 1997, forty-four patients with intracranial meningioma were treated by postoperative external irradiation. Of the 44 meningiomas, 18 transitional, 13 meningotheliomatous, 6 hemangiopericytic, 4 atypical, 2 fibroblastic and 1 malignant meningioma were identified. We classified all patients into two groups by the histology. The benign group was consisted of the meningotheliomatous, transitional and fibroblastic types. The malignant group was consisted of the atypical, hemangiopericytic and malignat types. In the means of surgery, 37 patients were resected incompletely and 7 patients were managed by biopsy only. After surgery, all patients were received postoperative external irradiation. Radiotherapy was deliverd using Co-60 or 4 MV photon beam to a total dose of 50 to 65 Gy (mean dose 57.4 Gy) with a 1.8 to 2 Gy per fraction. The median follow-up was 48 months (range : 21 $\~$ 101 months). Multivariate analysis of the Influence by age, sex, location, histology and radiation dose on local control has been done using Cox's proportional hazard model. Results : 5-year local control rate was 93.8$\%$ for the benign histology and 51.8$\%$ for the malignant histology (p=0.0110) and overall local control rate at 5 years was 87.4$\%$. The analysis of the prognostic factors, such as age, sex, location, and radiation dose were not significant except for the histology. Conclusion : Adjuvant postoperative external irradiation appears to be significantly improved local control in the patients with incompletely resected meningiomas.

We report an unusual case of left atrial auricular abscess which was successfully treated by surgical resection, treatment with antibiotics and mediastinal irrigation. A 9-year-old female patient with previous history of urinary tract infection was admitted because of persistent fever. Echocardiography and magnetic resonance imaging revealed massive pericardial effusion and a mass lesion at the left upper cardiac border. Pericardiocentesis isolated Staphylococcus aureus on culture. The patient underwent mass removal under cardiopulmonary bypass. The mass was located within the left atrial auricular wall with fibropurulent abscess formation inside. Postoperative mediastinal irrigation was performed. Pathologic examination of the mass showed organized thrombi with chronic fibrosing mural endocarditis. She discharged on the 21st postoperative day without complication.

A 69-year-old man was admitted due to blood-tinged sputum. The preoperative examination revealed 5${\times}$2.8cm sized nodular mass on left upper lobe of the lung. The patient underwent left upper lobectomy and radical Iymph node dissection under impression of lung cancer. Postoperative pathologic examination revealed as primary choriocarcinoma of the lung. The patient expired at postoperative 58 days despite meticulous postoperative care. We planned on immediate adjuvant chemotherapy but was delayed due to postoperative pneumonia and the choriocarcinoma progressed rapidly. Primary choriocarcinoma is an extremely rare clinical entity in lung cancer with no established therapeutic guidelines available. We report a case of the primary pulmonary choriocarcinoma which was diagnosed postoperatively.

We have experienced a case of pleural aspergillosis. A 50 year old female complained of malaise, anorexia, coughing with sputum, and right sided pleuritic chest pain of two weeks' duration. About ten years ago, she had been treated for pulmonary tuberculosis with medication. Chest radiography showed right pyopneumothorax with cavitation in the rig t upper lung and Chest computed topography revealed right loculated pyopneumothorax with cavity formation suggesting bronchopleural fistula. Decortication and wedge resection with pleurectomy were performed. The postoperative course was satisfactory and has been in good condition up to now. Pleural aspergillosis is a very rare and potentially life-threatening disease, but we have had good results without significant complications by treatment with systemic antifungal drugs and surgical operation.

Coronary restenosis is still regarded as Achilles' Hill of interventional cardiology despite relentless efforts of many investigators. Recent experimental and clinical studies have suggested that both gamma and beta radiation can reduce restenosis after angioplasty. Currently, intracoronary brachytherapy for the prevention of restenosis has become a new evolving treatment modality in interventional cardiology. This report discusses a physical aspect of gamma and beta radiation, initial clinical results and delivery systems used in intracoronary brachytherapy. We shall take a brief overview of methods and their advantages in intra-coronary brachytherapy. Future work should provide further insight for the best way of treating restenosis.
