Although many methods have been developed to correct the aging process of the head and neck, the correction of nasolabial folds still remains a difficult area. The difficulty of correcting nasolabial fold is due to the anatomical location and the difference of aging process. From March 2000 to February 2001, the authors operated on 10 aging face patients using face lift with SMAS and FAME(Finger-assisted malar fat pad elevation) technique. The authors repositioned the SMAS-platysma flap posterosuperiorly and used finger dissection of the malar fat pad enabling a 3-dimensional correction and repositioning of the fat pad without detachment of the zygomatic ligament. The finger dissection of the malar fat pad attached to the skin enables a more anatomical correction of the malar fat pad with a more natural looking layer and longer lasting results in addition to decreased hematoma, edema and postoperative pain compared to previous methods.

OBJECTIVE: Our aim was to figure out whether volumetric gray-scale histogram difference between anterior and posterior cervix can indicate the extent of cervical consistency. METHODS: We collected data of 95 patients who were appropriate for vaginal delivery with 36th to 37th weeks of gestational age from September 2010 to October 2011 in the Department of Obstetrics and Gynecology, Korea University Ansan Hospital. Patients were excluded who had one of the followings: Cesarean section, labor induction, premature rupture of membrane. Thirty-four patients were finally enrolled. The patients underwent evaluation of the cervix through Bishop score, cervical length, cervical volume, three-dimensional (3D) cervical volumetric gray-scale histogram. The interval days from the cervix evaluation to the delivery day were counted. We compared to 3D cervical volumetric gray-scale histogram, Bishop score, cervical length, cervical volume with interval days from the evaluation of the cervix to the delivery. RESULTS: Gray-scale histogram difference between anterior and posterior cervix was significantly correlated to days to delivery. Its correlation coefficient (R) was 0.500 (P = 0.003). The cervical length was significantly related to the days to delivery. The correlation coefficient (R) and P-value between them were 0.421 and 0.013. However, anterior lip histogram, posterior lip histogram, total cervical volume, Bishop score were not associated with days to delivery (P >0.05). CONCLUSION: By using gray-scale histogram difference between anterior and posterior cervix and cervical length correlated with the days to delivery. These methods can be utilized to better help predict a cervical consistency.

Central anticholinergic syndrome is defined as an absolute or relative reduction in cholinergic activity in the central nervous system and has a wide variety of manifestations. It is associated with almost any drug given during anesthesia, except neuromuscular relaxants, and treated with the cholinesterase inhibitor physostigmine. The diagnosis of central anticholinergic syndrome is often made when symptoms resolve promptly after the administration of physostigmine. We present a case of a central anticholinergic syndrome diagnosed by treatment with physostigmine, in a patient who received closure of patent foramen ovale associated with stroke.

BACKGROUND: The adequate management of mild to moderate dilatation of the ascending aorta during cardiac operations remains controversial. In this study, we present the short-term outcomes of 90 patients undergoing ascending aortic wrapping with a Dacron graft during other cardiac operations. MATERIALS AND METHODS: From March 2008 to January 2011, 90 consecutive patients underwent treatment for ascending aortic aneurysm using the external wrapping technique during the concomitant procedure. The study group consisted of 49 male and 41 female patients with a mean age of 58.7+/-13 years. The primary cardiac surgical procedures were coronary artery bypass grafting (CABG) in 3, aortic valve replacement in 2, and aortic valvuloplasty in 85 patients (isolated in 62 and combined with CABG or mitral valvuloplasty in 23). The ascending aorta diameter was measured using a computed tomography scan within 4 weeks after surgery, and was compared with the preoperative value. RESULTS: The diameters of the ascending aorta wrapped with the Dacron graft were significantly reduced within a month after surgery from 46.4+/-4.3 mm to 33.0+/-3.5 mm (p<0.05). There was no early mortality or major surgical complication. During the mean follow-up period of 15.4+/-5.2 months, there was only one late death caused by septic multiorgan failure. CONCLUSION: Dacron wrapping of the ascending aorta offers excellent results with very low mortality and morbidity, and it can be regarded as a safe and effective method for the treatment of moderately dilated ascending aorta in selected patients.

PURPOSE: The concentration of soluble transferrin receptor (sTfR) is estimated as an iron parameter to evaluate erythropoiesis and iron status. The aim of our study is to evaluate the correlation between sTfR concentration and inflammatory parameters and to distinguish iron deficiency anemia from anemia of inflammation. METHODS: One hundred and forty-four infants younger than two years of age who visited Gyeongsang University Hospital for 7 years from 2000 to 2006 were enrolled. Patients who had hemoglobin (Hb) <11 g/dL and ferritin <12 mg/L were excluded. Routine hematologic lab, serum ferritin, sTfR, and inflammatory markers [C-reactive protein(CRP), interleukin-6(IL-6), and absolute neutrophil count (ANC)] were investigated. RESULTS: In all patients, the sTfR concentration showed a correlation with Hb, ferritin, MCV, and ANC, but not with CRP and IL-6. In multiple regression models, positive correlations were found between sTfR concentration and IL-6 (r=0.078, P=0.043), and negative correlations were found between sTfR concentration and ANC (r=-0.117, P=0.033) and MCV (r=-0.027, P=0.009). CONCLUSION: sTfR concentration was influenced by inflammatory parameters. Therefore, sTfR does not appear to be a useful parameter for discriminating between iron deficiency anemia and anemia of inflammation in infants.

BACKGROUND: Because of the heterogeneity of human mesenchymal stem cells (MSCs), methods for cell expansion in culture and the effects on gene expression are critical factors that need to be standardized for preparing MSCs. We investigated gene expression patterns of MSCs with different seeding densities and culture times. METHODS: Bone marrow-derived MSCs were plated at densities from 200 cells/cm2 to 5,000 cells/cm2, and the gene expression patterns were evaluated over time using a reverse-transcription polymerase chain reaction assay. RESULTS: The mRNA levels of factors that play a critical role in cell migration and tissue regeneration, such as podocalyxin-like protein (PODXL), alpha4-integrin, alpha6-integrin, and leukemia inhibitory factor (LIF), were higher in MSCs plated at 200 cells/cm2 than in MSCs plated at 5,000 cells/cm2. The mRNA levels of these factors gradually increased for 10 days and then decreased by day 15 in culture. MSCs seeded at 200 cells/cm2 that were cultured for 10 days expressed high levels of Oct-4 and Nanog. Indoleamine 2,3-dioxygenase, cyclooxygenase-1, and hepatocyte growth factor expression were upregulated in the presence of the proinflammatory cytokine interferon-gamma in these cells. CONCLUSION: We found differences in the gene expression patterns of MSCs under different culture conditions. MSCs from 10-day cultures seeded at a low density were efficiently expanded, expressed PODXL, alpha6-integrin, alpha4-integrin, and LIF, and maintained properties like stemness and immunomodulation. Therefore, ex vivo expansion of MSCs maintained for an adequate culture time after plating at low cell density can provide an effective regenerative medicinal strategy for cell therapies using MSCs.

BACKGROUND AND OBJECTIVES: The postoperative outcomes of patients with severe aortic regurgitation (AR) and a low ejection fraction (EF) were elucidated. SUBJECTS AND METHODS: The study group consisted of 201 consecutive patients that underwent corrective surgery for isolated AR. The clinical data of patients with a preoperative EF<50% (n=59, group I) and of patients with an EF> or =50% (n=142, group II) were compared. The clinical follow-up duration was 3.2+/-2.4 years. RESULTS: There was no operative mortality for patients in both groups. Group I patients showed significant improvement of the EF after surgery, from 41+/-6% to 53+/-12% (p<0.001) and the EF (53+/-12 vs 56+/-1%, p=0.09) at follow-up was not significantly different between patients in the two groups. The 5-year survival rate was 70.5+/-8.9% for group I patients and 88.0+/-3.5% for group II patients (p=0.06). The cumulative incidence of congestive heart failure at 5 years was significantly higher in group I patients (32.1+/-9.7% vs 8.5+/-3.1%, p=0.003). Independent determinants of development of congestive heart failure in group I patients were age [hazards ratio (HR)=1.1, 95% confidence interval (CI)=1.02-1.16, p=0.01] and EF (HR=0.82, 95% CI=0.69-0.97, p=0.02). The best cut-off value of the preoperative EF in predicting the development of congestive heart failure was 41.5%, with a sensitivity and specificity of 90.9% and 68.9%, respectively. CONCLUSION: A relatively high 5-year survival rate without operative mortality is anticipated in patients with reduced a preoperative left ventricular ejection fraction (LVEF) and the incidence of congestive heart failure was higher when compared to patients with a normal preoperative LVEF, which could be predicted by the level of the preoperative LVEF.
