PURPOSE: The purpose of this study was to describe the anglographic finding and clinical result of transarterial embolotherapy(TAE) in patients with injuries of renal artery branches by blunt trauma. MATERIALS AND METHODS: The study was based on retrospective analysis of seven cases, in which TAE was attempted for the control of traumatic renal arterial bleeding. All procedures were performed via the transfemoral approach. TAE was performed with stainless steel coil in two cases, Gelfoam in one case, and Gelfoam and stainless steel coil in four cases. RESULTS: Angiographic findings of vascular injuries were pseudoaneurysm in four cases, extravasation in two cases and arteriocalyceal fistula in one case. All procedures were performed successfully without complication. CONCLUSION: Pseudoaneurysm is a common anglographic finding in patients with injury of renal artery branches and TAE is considered a safe and effective method for treating such cases.

OBJECTIVE: To evaluate the degree of streptococcal colonization in Korean pregnant women. METHODS: The study comprised of 153 singleton pregnant women who visited Severance Hospital for delivery, and their neonates. Specimens for GBS culture were collected by a sterile cotton swab from lower vagina and cervix of pregnant women, and from ear canal and throat of neonates. They were first cultured for 48 hours in Todd-Hewitt broth and then subcultured onto Tryptose blood agar plates(Difco). Group B streptococci were confirmed by the presence of beta-hemolysis and a positive reaction with Phadebact group B Streptococci reagent(Karo Biodiagnostics AB, Huddinge, Sweden). RESULTS: The prevalence of positive cultures in pregnant women and neonates were 2.61%(4/153) and 0%(0/4), respectively. In the study population there was a case of suspicious group B streptococcual sepsis in an infant whose mother was colonized. CONCLUSIONS: In our study the GBS colonization rate in Korean pregnant women was significantly lower than that of other countries. The reason for this difference may be associated with a racial differences, or social factors such as socio-economic status or a life style.

Annuloaortic ectasia, cystic medial degeneration of the afflicted aortic wall leading to progressive dilatation, is often accompanied by Marfan's syndrome. Some portions of intimal flap is commonly demonstrated along the aorta in the noninvasive diagnosis of aortic dissection. We report the first case of circumscribed aortic dissection developed in a 28 year old obese non-Marfanoid patient. He was transferred after thrombolytic therapy at a community hospital because of severe chest pain and ST segment elevation. Transthoracic echocardiography showed markedly dilated aortic root, moderate amount of pericardial effusion, mild aortic regurgitation in spite of normal regional wall motion of left ventricle. Intimal flap, characteristic of aortic dissection, was not seen with computed tomography. Intimal tear was demonstrated just above aortic valve only by transesophageal echocardiography. Two parallel intimal tear and small circumscribed dissection was demonstrated by autopsy.

BACKGROUND: Adipose-derived stem cells (ASCs) are mesenchymal stem cells that have recently been applied to tissue repair and regeneration. Keratinocytes and dermal fibroblasts play key roles in cutaneous wound healing. OBJECTIVE: We investigated the paracrine effects of ASCs on HaCaT cells (i.e., immortalized human keratinocytes) and human dermal fibroblasts to explore the mechanism of the effects of ASCs on cutaneous wound healing. METHODS: HaCaT cells and primary cultured human dermal fibroblasts were treated with 50% conditioned medium of ASCs (ASC-CM). Viability, in vitro wound healing, and fibroblast-populated collagen lattice contraction assays were conducted, and reverse transcription-polymerase chain reaction (RT-PCR) for the type I procollagen alpha1 chain gene was performed. RESULTS: The proliferation of HaCaT cells and fibroblasts was increased by ASC-CM in the viability assay. ASC-CM promoted in vitro wound healing of HaCaT cells and increased the contraction of the fibroblast-populated collagen lattice. RT-PCR showed that the transcription of the type I procollagen alpha1 chain gene in fibroblasts was upregulated by ASC-CM. CONCLUSION: The stimulatory effect of ASC on cutaneous wound healing may be partially mediated by paracrine effects of ASCs on other skin cells. Application of ASCs or ASC-derived molecules could be an innovative therapeutic approach in the treatment of chronic wounds and other conditions.

The numb chin syndrome (NCS) is characterized by chin or lower lip numbness restricted to the distribution of the mental nerve (the distal trigeminal nerve). The authors report a patient whose initial symptom of tumor recurrence was unilateral numbness of the chin. A 65-year-old male was admitted because of paresthesia around the left chin and left lower lip. Neurologic examination revealed hypesthesia on the left side of chin, lower lip and buccal mucous mem-brane. Bone scan (Tc-99m MDP) showed focal hot uptakes on the left mandible and left first rib. Brain CT with bone window setting showed a focal osteolytic lesion in the bone marrow of the left mandibular canal without destruction of bone cortex. Both coronal T1 weighted image and axial T2 weighted image showed focal low signal intensities on the left ramus. The pathophysiologic mechanism could be understood by identification of the pathologic focus.

From May, 1975 to August, 1986, we experienced 21 patients with ruptured aneurysm of the sinus of Valsalva. 1) Their ages ranged from 15 to 52 years with a mean age of 26.7 years, and 14 patients were male and 7 patients were female. Among 18 cases of which aneurysms occurred on the right sinus of Valsalva, 15 cases (83%) ruptured into the right ventricle, 1 case (6%) ruptured into the right atrium and 2 cases (11%) ruptured into the pulmonary artery. All 3 cases of which aneurysms occurred on the noncoronary sinus ruptured into the right atrium. 2) Clinical symptoms consisted of dyspnea (95%), palpitation (81%), chest pain (43%), orthopnea (33%), cough (14%), hemoptysis (5%), oliguria (5%), and fever (5%). In all patients continuous heart murmur was audible. Hepatomegaly (48%), pulmonary basal rale (14%), and pretibial pitting edema (19%) were also observed. 3) In all patients diagnosis was made with cardiac catheterization and angiography, and confirmed by operation excetpt one case. 4) Among 20 patients who had been performed corrective surgery, ventricular septal defect was observed in 16 patients (85%), aortic insufficiency in 5 patients (25%), pulmonary infundibular stenosis in 1 patient (5%), patent foramen ovale in 1 patient (5%), and tricuspid insufficiency in 1 patient (5%). Ventricular septal defect was observed in all 16 patients whose aneurysms of the right coronary sinus of Valsalva ruptured into the right ventricle and the pulmonary artery. 5) All patients survived operation, and no postoperative complication was found except 1 patient to whom reoperation was performed because of postoperative aortic insufficiency and detachment of the patch closure for ventricular septal defect. There was symptomatic improvement in all patients.
