PURPOSE: We investigated the autonomic nervous and complex modulation of heart rate and peripheral blood volume, and linear and nonlinear coupling between heart rate and peripheral blood volume in full-term and preterm infants. METHODS: In twenty healthy preterm infants and twenty full-term infants at postconceptional age of 30-37 and 38-41 weeks each, we recorded electrocardiogram and photoplethysmogram simultaneously during sleep in the supine position. To evaluate the autonomic and complex modulation, we performed power spectral analysis and analysis of the univariate nonlinear determinism. To quantify degree of linear and nonlinear couple between heart rates and peripheral blood volume, analyses of cross spectrum and bivariate nonlinear determinism were performed respectively. RESULTS: In the analysis of heart rates, preterm infants had significantly lower normalized high-frequency power (20.3+/-7.7% vs 30.7+/-15.1%, P<0.05), higher low-to high-frequency power ratio (3.0+/-2.1 vs 1.9+/-1.6, P<0.05), and significantly lower univariate prediction error (2.9+/-1.3% vs 4.1+/- 2.8%, P<0.05) when compared to full-term infants. In the analysis of peripheral blood volume, they showed no significant differences. Cross spectrum in all frequency ranges showed no significant difference between them. But preterm infants showed a significantly higher bivariate nonlinear prediction error (4.8+/-3.8% vs 3.1+/-2.2%, P<0.05) and a lower statistical coupling index (16.6+/-10.4 vs 22.9+/-9.2, P<0.05) than full-term infants. CONCLUSION: Compared to full-term infants, the heart rates of preterm infants are less modulated by cardiac parasympathetic activity and less complex. Furthermore, their peripheral blood volume was less nonlinearly coupled to heart rate.

OBJECTIVE: This study is directed to determine whether the concentrations of serum amyloid A (SAA) in maternal serum could be used to predict a tocolytic failure in preterm delivery, by comparing with other factors associated with inflammation. METHODS: A total of 100 pregnant women from September, 2000 to August, 2001 received continuous prenatal care and underwent delivery in our hospital was enrolled in the study. Gestational age was ranged between 20 and 37 weeks. Subjects were divided into four groups (group I, no preterm labor and no premature rupture of membranes [n=38]; group II, premature rupture of membranes and no preterm labor [n=12]; group III, preterm labor and no premature rupture of membranes [n=34]; Group IV, preterm labor and premature rupture of membranes [n=16]). The levels of SAA, CRP, ESR, and WBC count were measured in maternal serum. RESULTS: SAA levles, CRP levels, and WBC count in patients with tocolytic failure were significantly higher than those in patients without tocolytic failure. SAA and CRP appeared to be significant factors by logistic regression analysis. From the ROC curve analysis of maternal SAA for the prediction of tocolytic failure, we set 6 mg/L as a cut-off value in this study. Sensitivity, specificity, positive predictive value, and negative predictive value were 76%, 72%, 47.5%, and 90%, respectively. As for CRP, 0.59 mg/dL was set as a cut-off value, and sensitivity, specificity, positive predictive value, and negative predictive value were 72%, 81.3%, 56.3%, and 89.7%, respectively. When cut-off values for both SAA and CRP were applied at the same time, sensitivity, specificity, positive predictive value, and negative predictive value were 60%, 92%, 71.4%, and 87.3%, respectively. CONCLUSION: This study showed that the measurement of maternal serum amyloid A may be a fast, non-invasive diagnostic method in the prediction of tocolytic failure in preterm delivery.

Extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) is usually indolent. Although it was reported recently that about 20-30% cases of MALT lymphoma presented with a disseminated disease at diagnosis, it was described as a disease localized at diagnosis and remaining stable for a prolonged period. However, only a few cases of MALT lymphoma involved the lung and gastrointestinal tract all at once. We report a case of a 73-year-old man with disseminated MALT lymphoma. He presented with non-productive cough, initial chest radiograph showed a nodule in the right lower lobe. The diagnosis of stage IV MALT lymphoma was made by CT scan, video-assisted thoracoscopic excisional biopy, gastrofiberscopic biopsy and bone marrow biopsy. The lymphoma involved the lung, stomach and bone marrow at the time of diagnosis. Because he refused chemotherapy, he discharged after Helicobacter pylori eradication without chemotherapy. Regular follow-up examination did not show any evidence of disease progression over 22 months.

Hyperreactio luteinalis(HL)referes to moderate to marked cystic bilateral enlargement of ovaries due to benign theca lutein cysts, usually related to hydatidiform mole or choriocarcinoma. After its first description by Berger in 1938, almost 53 cases of HL unassociated with trophoblastic disease have been reported in the literature. We encountered one such case in a 34 years old female which was incidentally diagnosed during cesarean section at term.

BACKGROUND: Venoveno bypass (VVB) has been used to achieve hemodynamic stability and decrease the incidence of renal dysfunction. However, VVB has many complications. The purpose of this study is to verify the safety of total clamping of the suprahepatic inferior vena cava (IVC) without VVB during orthotropic liver transplantation (OLT) in terms of anesthetic management. METHODS: Twenty-five patients without preoperative renal dysfunction who underwent primary OLT were enrolled in this study. Hemodynamic data and blood gas measurements were collected 1 hour after incision, 30 minutes after IVC total clamping and 30 minutes after reperfusion. Postoperative laboratory data, including blood urea nitrogen (BUN), creatinine (Cr) and glomerular filtration rate (GFR), were assessed at postoperative day (POD) 0-7, 30, 90, 180 and 1 year. RESULTS: Mean blood pressure was well maintained during IVC total clamping with infusion of inotropics. There was no case of severe acidosis (pH < 7.2) during the anhepatic period. The immediate postoperative Cr and GFR were not significantly different from those of the preoperative values. BUN increased from POD 1 and decreased after POD 6, while Cr increased at POD 90 only. CONCLUSIONS: In patients without preoperative renal dysfunction, when IVC was totally clamped, VVB does not need to be routinely performed to maintain hemodynamics during the anhepatic phase and renal function after OLT.

Anomalous right coronary artery arising from the left sinus of Valsalva is rare, but not protected from ather-osclerotic disease. Major factor determining successful angioplasty is the selection of the appropriate guiding catheter to provide optimal coaxial backup support. We report the first case of successful transradial stenting of an anomalous right coronary artery originating from the left sinus of Valsalva.

STATEMENT OF PROBLEM: In the partially edentulous patients, removable partial dentures have been working as a important treatment modality. Clasps, a kind of direct retainers, received some amount of stresses during the insertion and removal of partial denture on the abutment tooth. PURPOSE: The study is to investigate stresses of the different clasps. MATERIAL AND METHODS: In order to investigate the degree of stresses, maxillary partial edentulism (Kennedy Class II, modification 1) was assumed and removable partial dentures were designed on it with three kinds of metallic materials; cobalt-chromium alloy, type IV gold alloy and commercially pure (c.p.) titanium. Aker's clasp was applied on the left second molar, RPA (mesial rest-proximal plate-Aker's) clasp was on the left first premolar and wrought wire clasp was on the right first premolar. Three dimensional, non-linear, dynamic finite element analysis method was run to solve this process. RESULTS: 1. Cobalt-chromium alloy had the highest von Mises stress value and c.p. titanium had the lowest one irrespective of the types of clasps. 2. In the Aker's clasps, stress on the retentive tips was shown shortly after the appearance of stresses of the middle and minor connector areas. These time lag was much shorter in the RPA clasps than in the Aker's clasp. 3. In general, retentive tips of wrought wire clasps had much less amount of stress than other clasps. CONCLUSION: The amount of stress was the highest in the RPA clasp and the lowest in the wrought wire clasp, in general.

PURPOSE: To compare and analyze the clinical outcomes after the traditional mini-flap technique and a new modified mini-flap technique for pterygium surgery. METHODS: This is a retrospective, clinical outcome study of 39 eyes that received the existing mini-flap technique from January, 2004 to August, 2005, and 142 eyes that received the modified mini-flap technique from September, 2008 to December, 2010. We analyzed the recurrence rate of each mini-flap technique and the difference between the group that experienced recurrence and the group that did not. We also analyzed the difference between the group that received the mini-flap technique and the group that received the modified mini-flap technique. RESULTS: The recurrence rate of pterygium patients who received the mini-flap technique was 10.3% (4/39). The rate of those who received the modified mini-flap technique was 2.1% (3/142), which is statistically lower (p = 0.040). However, compared from the recurrence rate of 6.1% (3/49) that was reported in 2008, the recurrence rate of the modified mini-flap technique did not show any statistical significance (p = 0.165). From the comparison of demographic factors of the patients in each surgical technique group, in both recurred and not recurred group, the patient group in the modified mini-flap technique group whose pterygium was recurrd was the youngest (p < 0.001). CONCLUSIONS: The newly applied modified mini-flap technique is not only a safe method with low recurrence rate compared to the traditional mini-flap technique, but also a reliable surgical technique in both primary and recurred pterygium.
