The purpose of this study was to elucidate the prevalence rate of tbe concomitant; atopic diseases in the patients with allergic rhinitis and, concurrently, the incidence of the atopic diseases in the families of the patients. A total of 40 patients who were referred to the department of dermatology, Kang Nam St. Marys Hospital, for the confirmative examinations of allergic srhiniti were taken for this study. The results were as follows, 1. The prevalence rate of concomitant atopic dermatitis in the sample patients was 22.5% and that of concomitant bronchial asthma was 12. 5% The prevalence rate of concomitancy with both diseases was 2.5% and that of concomitancy with atopic dermatitis and/or bronchial asthma was 37.5%. 2. The frequency of the associated manifestations, in descending order, was allergic conjunctivitis (30%), urticaria or angioedema (25%), insect sting (22.5%), oral symptoms (5%), migrane or headache (5%), immediate drug reactions (2.5%) and gastrointestinal symptoms (2.5%).

BACKGROUND: In anesthesia for cesarean section, there is an increased incidence of maternal awareness because a light plane of general anesthesia is chosen for fetal safety and rapid recovery. Propofol may be the choice if smooth induction and rapid maternal recovery are desired. Authors tried to know that propofol has properties which suggest that it might be useful alternative to thiopental and enflurane. METHODS: Forty patients in ASA class I or II scheduled for cesarean section were allocated randomly to either propofol (n=20) (P) or thiopental-enflurane (n=20) (T-E) group. Anesthesia was induced with propofol 2 mg/kg IV and maintained by continuous infusion of propofol 8 mg/kg/hr in P group and was induced with thiopental 4 mg/kg IV and maintained by inhalation of 1 vol% enflurane in T-E group. All patients received vecuronium 0.1 mg/kg and 50% N2O-O2. Blood pressure, heart rate, Apgar score, umbilical arterial blood gas analysis and the incidence of maternal awareness using the isolated forearm technique (IFT) were evaluated. RESULTS: Diastolic pressure was decreased in P group than T-E group at 10 min after delivery. Heart rate was increased in P group than T-E group at immediate after extubation (p<0.05). For apgar score, umbilical artery gas analysis and maternal awareness there were not significant differences between two groups. CONCLUSIONS: In comparison with thiopental-enflurane, propofol infusion (8 mg/kg/hr) coupled with N2O was proved to be clinically satisfactory anesthesia for cesarean section with no adverse effects on both mother and neonate.

OBJECTIVE: Many evidences raise the possibility that the panic disorder (PD) patients with respiratory subtype (RS) may have characteristic structural abnormalities. We aimed to explore the structural differences between PD patients with and without the respiratory symptoms. METHODS: Patients with PD were recruited from the Department of Psychiatry at Korea University Anam Hospital. Respiratory subtype (RS) was diagnosed when at least 4 out of 5 of the following respiratory symptoms were present during the panic attack: fear of dying, chest pain/discomfort, shortness of breath, paresthesias, and a choking sensation. We acquired high-resolution MRI scans and used FreeSurfer to obtain a measure of cortical thickness for each patient. RESULTS: Cluster based analysis revealed significantly decreased cortical thickness in the left hemisphere in the caudal-middle-frontal, superior frontal, and posterior parietal areas in the RS group. No significant difference was observed in any of the limbic areas. CONCLUSION: Respiratory symptoms of panic disorder were associated with a reduction in cortical thickness in the left frontal and parietal areas. This finding leads to the assumption that the frontoparietal network is the crucial component in a larger cortical network underlying the perception of dyspnea in RS.

PURPOSE: We describe our successful experience using a capsular tension ring (CTR) and iris repair during cataract surgery in a patient with bilateral coloboma. METHODS: A 67-year-old woman had no history of trauma, but had zonular deficiency and inferonasal iris defects in both eyes. An extracapsular cataract extraction and intraocular lens (IOL) scleral fixation was performed in the left eye. A CTR was implanted in the right eye through a sclerocorneal incision. After the IOL was placed centrally in the capsular bag, two paracenteses were made at the limbus (5 o'clock and 7 o'clock). A long, straight needle was passed through the 7 o'clock paracentesis site into a angled, blunt tipped 27 gauge needle inserted from the 5 o'clock paracentesis. The two needles were pulled out at 5 o'clock. After inserting the long needle into the blunt tipped needle at 7 o'clock, both were passed back through the 7 o'clock paracentesis site. The needles were pulled out again at the 5 o'clock paracentesis site tied. Equal tension was used to tie both sides. RESULTS: Visual acuity improved to 20/20 in the right eye. CONCLUSIONS: Both capsular tension ring implantation and iris repair was successfully performed at the time of cataract surgery in a coloboma patient, which resulted in improvements in visual function and cosmesis.

The chronic myelogenous leukemic K562 cell line carrying Bcr-Abl tyrosine kinase is considered as pluripotent hematopoietic progenitor cells expressing markers for erythroid, granulocytic, monocytic, and megakaryocytic lineages. Here we investigated the signaling modulations required for induction of erythroid differentiation of K562 cells. When the K562 cells were treated with herbimycin A (an inhibitor of protein tyrosine kinase), ras antisense oligonucleotide, and PD98059 (a specific inhibitor of MEK), inhibition of ERK/MAPK activity and cell growth, and induction of erythroid differentiation were observed. The ras mutant, pZIPRas61leu-transfected cells, K562-Ras61leu, have shown a markedly decreased cell proliferation rate with approximately 2-fold doubling time, compared with the parental K562 cells, and about 60% of these cells have shown the phenotype of erythroid differentiation. In addition, herbimycin A inhibited the growth rate and increased the erythroid differentiation, but did not affect the elevated activity of ERK/MAPK in the K562-Ras61leu cells. On the other hand, effects of PD98059 on the growth and differentiation of K562-Ras61leu cells were biphasic. At low concentration of PD98059, which inhibited the elevated activity of ERK/MAPK to the level of parental cells, the growth rate increased and the erythroid differentiation decreased slightly, and at high concentration of PD98059, which inhibited the elevated activity of ERK/MAPK below that of the parental cells, the growth rate turned down and the erythroid differentiation was restored to the untreated control level. Taken together, these results suggest that an appropriate activity of ERK/MAPK is required to maintain the rapid growth and transformed phenotype of K562 cells.

BACKGROUND AND OBJECTIVES: To evaluate the feasibility and the short- and mid-term follow-up outcomes of endovascular stent-graft implantation in patients with Stanford type B aortic dissection. SUBJECTS AND METHODS: Twenty-eight patients with Stanford type B aortic dissection were evaluated. An aortogram was performed immediately after the procedure and a follow-up computed tomography (CT) scan was performed within one week, between 3 and 6 months, and annually thereafter. Clinical status was also evaluated at the same time. RESULTS: Endovascular stent-graft implantation at the target site was successful in 27 patients (96.4%). There were primary endoleaks in 6 patients and one case of procedure failure owing to migration of the stent-graft; and no procedure-related mortality. The number of patients with early complications requiring treatment was 2 (2/27, 4%). Fourteen patients experienced postimplantation syndrome (14/27, 52%). The average follow-up period was 22.1+/-17.5 months. Complete resolution or thrombosis of the false lumen was achieved in 14 patients and partial thrombosis was achieved in 10 patients. Operative treatments were required in three patients due to a progressing dissection or new dissection. There were no deaths and no instances of aneurysm or aortic rupture during the follow-up period. CONCLUSION: Endovascular stent-graft implantation for Stanford type B aortic dissection is a feasible, safe, and effective treatment modality. All patients who underwent surgery had a persisting leak. Therefore, regular evaluation of the aortic dissection and management of endoleaks were crucial for a favorable outcome in endovascular stent-graft implantation for a Stanford type B aortic dissection.

PURPOSE: This study was designed to evaluate whether magnetic resonance imaging (MRI) is appropriate for detecting early changes in the mandibular bone marrow and pulp tissue of rats after high-dose irradiation. MATERIALS AND METHODS: The right mandibles of Sprague-Dawley rats were irradiated with 10 Gy (Group 1, n=5) and 20 Gy (Group 2, n=5). Five non-irradiated animals were used as controls. The MR images of rat mandibles were obtained before irradiation and once a week until week 4 after irradiation. From the MR images, the signal intensity (SI) of the mandibular bone marrow and pulp tissue of the incisor was interpreted. The MR images were compared with the histopathologic findings. RESULTS: The SI of the mandibular bone marrow had decreased on T2-weighted MR images. There was little difference between Groups 1 and 2. The SI of the irradiated groups appeared to be lower than that of the control group. The histopathologic findings showed that the trabecular bone in the irradiated group had increased. The SI of the irradiated pulp tissue had decreased on T2-weighted MR images. However, the SI of the MR images in Group 2 was high in the atrophic pulp of the incisor apex at week 2 after irradiation. CONCLUSION: These patterns seen on MRI in rat bone marrow and pulp tissue were consistent with histopathologic findings. They may be useful to assess radiogenic sclerotic changes in rat mandibular bone marrow.

Subcutaneous and topical epinephrine are widely used for hemostasis during dermatologic procedure. There was substantial variation in the amount of systemic absorption on the basis of patient's general condition, blood supply of wounds. Increased or unpredictable absorption after topical administration may increase anesthetic and cardiovascular risks. There have been no reports about cardiovascular complications developed during laser resurfacing. We experienced a case of transient hypertension, cardiac arrhythmia and ST-depression during whole face resurfacing by Erbium-Yag laser due to application of high concentration epinephrine gauze on the face. The hypertension and arrhythmia were normalized in 2 minutes, and ST-depression was sustained for about 4 hours.
