We describe a case of infrarenal aortic hypoplasia in a 52-yr-old woman who presented with claudication. Computed tomographic angiography revealed an abrupt absence of the infrarenal aorta, with collateral flow reconstituting the iliofemoral systems. After a polytetrafluoroethylene graft was interposed between the aortic stump and the iliac bifurcation, the patient's claudication resolved.

Congenital central hypoventilation syndrome (CCHS) is a life-threatening disorder with apnea and cyanosis during sleep requiring immediate endotracheal intubation during the first day of life. The PHOX2B gene has been identified as the major gene involved in CCHS. This is the first report of a Korean neonate with CCHS confirmed to have a PHOX2B mutation with expanded alleles containing 20 polyalanine repeats that is a relatively small number compared to previous cases. The patient required intermittent ventilator support during sleep only and did not suffer from any other disorders of the autonomic nerve system. He consistently needs ventilator support during sleep and remains alive. Analysis of PHOX2B gene is useful for diagnosis and appropriate therapeutic intervention of CCHS patients.

Neonatal Medicine 2015;22(4):187-191
PURPOSE: Little research has been conducted on adverse drug reactions in neonates, particularly in Korea, where no studies have been reported. METHODS: We conducted a retrospectively study using medical records in a neonatal intensive care unit from August 1, 2013 to July 31, 2014. The adverse drug reactions were evaluated according to the Naranjo algorithm, World Health Organization-Uppsala Monitoring Centre, and the Korean adverse drug reaction algorithm. RESULTS: Of the 410 infants hospitalized during the study period, 57 cases of adverse drug reactions were reported in 40 infants (9.8%). The average gestational age was 28.4+/-4.3 weeks, the average birth weight was 1,184.1+/-622.0 g, and the adverse drug reactions were reported at an average of 21.0+/-29.7 days after birth. Causative agents were identified as electrolytes (36.8%), respiratory medication (14.0%), total parenteral nutrition (12.3%), lipid emulsion (10.5%), antibiotics (7.0%), non-steroidal anti-inflammatory drugs (NSAIDs, 7.0%), sedatives (7.0%), vaccine (3.5%), and an antiviral medication (1.8%). Of the 57 cases, 55 (96.5%) cases demonstrated meaningful adverse drug reactions, defined as those given a score of "possible or above" in all 3 adverse drug reaction algorithms. CONCLUSION: More emphasis is warranted in the field of neonatal adverse drug reactions.

PURPOSE : To evaluate the frequency of urinary tract anomalies in male neonates less than 3months old who presented with urinary tract infection(UTI) and to evaluate a appropriate imaging approach after first UTI. MATERIALS AND METHODS : During a period of 5 years, from March 1994 to February 1999, 65 male infants less than 3months old(range: 4-92 days, mean: 43 days) with UTI were evaluated. Ultrasound(US) and Voiding cystourethrogram(VCUG) were done in 60 patients. Due to refusal and technological problem, 5 patients were missed. 99mTc-dimercaptosuccinic acid renal scan (99mTc-DMSA renal scan) was recommended to most patients but performed in 40 patients. Renal scan was performed at least 3 months later after urinary tract infection. RESULTS : Urinary tract anomalies were found in 26 of 65 infants. Twenty-six had vesicoureteral reflux(VUR), two had both VUR and double ureter, two had both VUR and posterior urethral valve. In patients with VUR, eight had renal scar or renal atrophies. In case of renal scar or atrophy, grades of VUR were III or above. CONCLUSION : We suggest that US and VCUG should be routinely performed in infants(<3months)with first UTI. 99mTc-DMSA renal scan should be performed only when renal parenchymal damage was observed in US and VUR grade III or above in VCUG.

BACKGROUND: As life span is increasing, so is interest about adult disease. Especially the number of postmenopausal women has increased, and postmenopausal symptoms have become a important problem causing low quality of life. Hormone replacement therapy was introduced to overcome these problems. Authors investigated to evaluate the effect of hormone replacement therapy on the quality of life of postmenopausal women. METHODS: From April to June 1997, we surveyed 188 postmenopausal women (91 women were on hormone replacement therapy, and 97 women were in the controlled group in Sungnam Central Hospital) with COOP/WONCA chart Korean version. RESULTS: COOP/WONCA chart (Korean version) is composed of seven dimensions, among these four dimensions (change in health, overall health, daily activity and pain) were shown statistically significant difference between two groups. But three dimensions (social activity, physical fitness and feelings) were not shown to be statistically different. Total mean score of COOP/WONCA chart showed statistically significant difference. CONCLUSIONS: To improve the quality of life of postmenopausal women, primary care physician should consider hormone replacement therapy along with proper patient selection and periodic follow up.

We report a case of central venous stenosis due to a structural deformity caused by a tuberculosis-destroyed lung in a 65-year-old woman. The patient presented with left facial edema. She had a history of pulmonary tuberculosis, and the chest X-ray revealed a collapsed left lung. Angiography showed leftward deviation of the innominate vein leading to kinking and stenosis of the internal jugular vein. Stent insertion improved her facial edema.

We report a case of unintentional intraoperative awareness during sevoflurane-remifentanil anesthesia in a 26 years old woman undergoing elective minimal invasive mitral valvuloplasty. Cardioprotective effects of sevoflurane were clinically most apparent when administered throughout the surgical procedure. Also use of sevoflurane during cardiopulmonary bypass decreases incidence of awareness. Although awareness during cardiac anesthesia has been previously described with sevoflurane, the implication of this case is that unexpected awareness can occur in patients with sevoflurane during cardiopulmonary bypass on cardiac surgery. Therefore, more attention is needed to use sevoflurane during cardiopulmonary bypass.

BACKGROUND: The carotid intima-media thickness (IMT) have been known to be related to the degree of atherosclerosis and cardiovascular risk factors. The aim of this study was to elucidate the relationship of IMT and the hemodynamic changes during anesthetic induction. METHODS: Two hundred fourteen patients scheduled for general anesthesia were studied. The blood pressures and heart rates during anesthetic induction and endotracheal intubation were measured. IMT was measured at right common carotid artery using M-mode ultrasonography after anesthesia, RESULTS: Mean IMT of the patients was 0.611 +/- 0.146 (0.34-0.96) mm. IMT was significantly related with age, systolic blood pressure, the changes of blood pressure after induction, and the changes of blood pressure after intubation. IMT was not related for basal heart rate and the changes of heart rate during anesthetic induction and intubation. CONCLUSIONS: IMT is related with the magnitude of blood pressure decreasing during anesthetic induction and increasing during intubation. The further study is needed to evaluate the relationship of IMT and hemodynamic changes during other anesthetic practice.

Pulmonary placental transmogrification (PT) is a rare lung disease that takes on the histologic appearance of placental chorionic villi. We herein report a case of PT in a 66-year-old woman who presented with a single nodule on chest radiography performed during a routine health examination. She had no complaints of any symptoms. Chest radiography showed a focal ill-defined nodular opacity in the right lower lobe; chest computed tomography revealed a 17-mm lobulated, focal irregular mass with fissural retraction in the right lower lobe, suggestive of lung cancer. Pathology of a percutaneous needle aspiration biopsy revealed papillary structures resembling placental villi. These were lined by cytotrophoblast-like cells and syncytiotrophoblasts. This characteristic pathologic finding led to a diagnosis of PT. PT of the lung is found mainly in bullous or cystic lesions. However, this patient presented with a single nodule on chest radiography.

BACKGROUND: Interleukin-6 (IL6) is an important regulator of cellular hypertrophy through the gp130/Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) pathway. We tested the hypothesis that IL6 and its downstream gp130/JAK2/STAT3 pathway participated in high glucose (HG)–induced podocyte hypertrophy. METHODS: IL6 levels in the media and lysates of podocytes were measured by enzyme-linked immunosorbent assay. Western blots were performed to determine the protein expression levels of gp130/JAK2/STAT3 among podocytes cultured with normal glucose (NG), NG + mannitol, NG + recombinant IL6, HG, and HG + IL6-neutralizing antibodies (IL6NAb). Immunoprecipitation was examined to determine whether gp130 interacted with JAK2 in response to HG or IL6. Podocyte hypertrophy was verified using protein/cell counts and flow cytometry. RESULTS: IL6 levels were significantly increased in the media and lysates of podocytes cultured in HG compared with the NG groups. The nuclear phospho-STAT3/STAT3 ratio was increased by HG and NG + IL6 and was attenuated in the HG + IL6NAb groups, indicating that nuclear STAT3 was activated following JAK2 and cytosolic STAT3 activation in response to IL6 secreted by HG-stimulated podocytes. Immunoprecipitation showed increased phospho-JAK2 recruitment to gp130 in the HG and NG + IL6 groups, and the addition of IL6NAb in the HG group significantly abrogated these increases. Podocyte hypertrophy was significantly increased in the HG and NG + IL6 compared with the NG condition and was diminished by the addition of IL6NAbs to the HG group. CONCLUSION: IL6 might play a prominent role in the local activation of JAK2/STAT3 in podocyte hypertrophy under HG conditions. In vivo studies examining this pathway are warranted.
