A 22 year old male with hemophilia B was scheduled for the correction of a right subtrochanteric femur fracture. Plasma concentration of coagulation factor IX in this patient was 50% of the normal level and the partial thromboplastin time was 57 seconds on the first day of hospital administration. We started the intravenous administration of facnyne injection (factor IX) 11 days before the operation when his plasma concentration was 20%. His plasma concentration was 40% on the operation day. The operation and general anesthesia were accomplished safely without severe hemorrhage or major complication. He received facnyne injection continuously until the 5th postoperative day: 25-43% of his plasma concentrations of factor IX was maintained. He had no problem with postoperative care.

BACKGROUND AND OBJECTIVES: Evaluation of right ventricular dysfunction in patients with pulmonary hypertension is useful for clinical management and it has prognostic implications. The purpose of this study was to evaluate the impact of pulmonary hypertension on the regional strain of the right ventricle and to assess the correlation between pulmonary arterial (PA) pressure and right ventricular (RV) strain. SUBJECTS AND METHODS: A total of fiftyone patients with chronic obstructive lung disease were classified into two groups on the basis of the presence of normal PA pressure (group I, PA pressure<35 mmHg, n=22) or high PA pressure (group II, PA pressure(35 mmHg, n=29), as estimated by the peak tricuspid regurgitation velocity on Doppler echocardiography. The left ventricular (LV) ejection fraction and RV fractional area change were assessed by conventional echocardiography, and the strain values were obtained from the RV, the LV free wall and the septum. RESULTS: The baseline characteristics were similar in both groups except for the peak PA pressure (group I: 30.2+/-3.9 mmHg, group II: 44.4+/-7.5 mmHg, p<0.00001). Group II had statistically reduced basal RV strain (-%) (20.3+/-7.1) compared to group I (24.1+/-6.7, p=0.033). The basal RV strain correlated with the PA pressure (r2=0.269, p=0.004). CONCLUSION: RV strain could determine regional RV dysfunction in patients with pulmonary hypertension.

Percutaneous endoscopic gastrostomy (PEG) has become a widely used and safe method for long-term enteral feeding in patients who are unable to tolerate oral feeding. Although a number of complications can occur following PEG placement, most of these complications are not life threatening. Serious complications occur rarely after this procedure and they include peritonitis, visceral perforation, major gastrointestinal bleeding, and necrotizing fasciitis. An esophageal perforation following PEG placement is very rare and predisposing factors include Zenker's or epiphrenic esophageal diverticuli, esophageal strictures, and mass lesions. We recently experienced a case of distal esophageal perforation following a PEG tube change. The predisposing esophageal perforation factor in this case was uncertain, and we successfully treated the patient with surgical intervention.

BACKGROUND: Hemoglobin dilution occurs after acute blood loss, by shifting extravascular blood components into the intravascular space, providing the theoretical possible to calculate amount of blood loss by comparing this difference.Assessing blood loss during the operative procedure is crucial to provide appropriate treatment, however there are few objective standards by which to make this assessment.In this study, we used the hemoglobin dilution method to predict blood loss following an operative procedure. METHODS: During the year 2007, 96 patients who had undergone lumbar spinal fusion surgery were enrolled in this study.On a retrospective basis, we investigated the weight, height, intraoperative blood loss, hemoglobin change, and the amount of transfused erythrocytes by reviewing anesthetic notes from the surgery. On the basis of these data, we calculated estimated blood loss by using Nadler's formula. RESULTS: The majority of study participants were female and average age was 60.1 yrs.We observed 2.3 g/dl decrement of postoperative hemoglobin, and estimated blood volume was 3,599 ml. Estimated blood loss was 853.7 ml, and observed blood loss was 1,070 ml, thus creating 217.1 ml difference.Analysis showed a moderate degree of correlation between observed and estimated values and a correlation coefficient of 0.49. We obtained regression equations of y = 0.828x + 363.5. CONCLUSIONS: Estimated blood loss was underestimated compared to observed values, by 20%, and this discrepancy is was attributed to ethnic differences. To predict a precise estimated blood loss, attempts to make a modified formula targeted to the Korean population are required.

BACKGROUND: Laparoscopic cholecystectomy and gynecologic pelviscopy need to induce pneumoperitoneum to allow visualization of the operative field, but the former requires a head-up position whereas the latter needs a Lithotomy-Trendelenburg position. The authors observed hemodynamic changes using an esophageal doppler monitor in both cases. METHODS: Eight females planned for laparoscopic cholecystectomy were assigned to Group 1 and 10 females for gynecologic pelviscopy were assigned to Group 2. Thiopental (5 mg/kg) and vecuronium (0.1 mg/kg) were used to induce general anesthesia. 50% O2-N2O and 1.5 vol.% isoflurane were used to maintain anesthesia. Mechanical ventilation was used with a tidal volume of 10 ml/kg and a respiratory rate of 12 breaths per minute. Mean arterial pressure, heart rate, end-tidal CO2 and peak airway pressure were measured and cardiac output, corrected flow time, and peak velocity were monitored using an esophageal doppler monitor in each group after inducing anesthesia, CO2 inflation, position change, and CO2 deflation. RESULTS: Mean arterial pressure increased in each group while changing position. No significant changes in the heart rate were observed in each group. End-tidal CO2 increased in each group after changing position, and remained elevated even with position reversal and deflation. Peak airway pressure was elevated in each group after CO2 inflation and increased more so with changing posture in group 2 (post inflation: 18.5 +/- 1.4 cmH2O, after position change: 21.4 +/- 2.0 cmH2O). Cardiac output and cardiac index were reduced after the induction of pneumoperitoneum in each group, and reduced more on changing posture in group 2 (CO: 5.9 +/- 2.0 L/min vs. 4.4 +/- 1.5 L/min, CI: 3.7 +/- 1.4 L/min/m2 vs. 2.7 +/- 1.1 L/min/m2). Stroke volume also reduced after changing posture in each group. Corrected flow time was not changed, but peak velocity decreased after CO2 inflation in each group (group 1: 97.4 +/- 30.0 cm/s vs. 78.9 +/- 27.3 cm/s, group 2: 111.9 +/- 14.1 cm/s vs. 88.3 +/- 12.6 cm/s). CONCLUSIONS: The Lithotomy-Trendelenburg position can augment the hemodynamic changes resulting from pneumoperitoneum. Therefore, additional caution is required in patients with cardiovascular disease who are undergoing gynecologic pelviscopy.

BACKGROUND: Abnormalities of the left ventricular (LV) diastolic dysfunction are common in patients with end-stage renal disease (ESRD). Recently, Doppler tissue imaging (DTI) has been introduced as a method to evaluate diastolic function or myocardial relaxation by measuring mitral annulus velocity during diastole. This study was undertaken to assess resting diastolic function and diastolic functional reserve during exercise in ESRD patients starting dialysis treatment. METHODS: Mitral inflow velocities by Doppler echocardiography and septal mitral annular velocities by DTI were measured at rest and during supine bicycle exercise in 22 new ESRD patients and 23 age- and sex-matched subjects with normal renal function as a control. RESULTS: LV end-diastolic and end-systolic dimensions, septal thickness, and left atrial volume index were significantly higher in patients with ESRD compared with those of controls (p<0.01). LV ejection fraction was significantly lower in ESRD group (p<0.05). There were no significant differences in mitral inflow velocities (E, E/A, DT) between the two groups except A velocity, which was significantly higher in ESRD group (p<0.01). However, early diastolic mitral annular velocity (E') at rest (5.3+/-1.3 cm/sec vs. 6.5+/-1.5 cm/sec, p=0.013) and augmentation of E' with exercise (deltaE') were significantly lower in ESRD group compared with controls (at 25W exercise, 1.3+/-1.6 cm/sec vs. 4.0+/-3.0 cm/sec, p=0.002; at 50W exercise, 3.3+/-2.3 cm/sec vs. 6.5+/-5.3 cm/sec, p=0.030). CONCLUSION: Unlike conventional mitral inflow parameters, longitudinal resting diastolic function and diastolic functional reserve during exercise assessed by DTI were significantly reduced in ESRD patients starting dialysis treatment.

BACKGOUND: The late referral to nephrologist was founded as independent risk factor of poor survival in hemodialysis patients. Patients referred lately are prone to initiate dialysis urgently through temporary catheter and the use of catheter increase the incidence of catheter related complications. But patients' survival may be influenced by multiple and more complex factors beside referral pattern and use of catheter. So we planed to evaluate the effect of referral pattern on patients' survival and related factors. METHODS: This analysis included 629 incident hemodialysis patients in single center. Demographical, clinical, laboratory data were collected retrospectively. Early referral was defined as first nephrology visit over 3 months prior to initiation of dialysis. Clinical characteristics were compared between early (ER) and late referral groups (LR). Survival analysis and Cox models were performed to assess the relationship of referral pattern and mortality. Significant differences were defined as p value less than 0.05. RESULTS: ER included 269 patients and their mean age, male proportion were not different from those of LR. In ER, pre-dialysis education program and nutritional counseling were offered much more than LR and lesser catheter usage, higher serum albumin at the initiation of dialysis. ER survived longer but in Cox models, only older age, presence of diabetes, lower serum albumin at the initiation of dialysis were independent risk factor for death (odds ratio 1.047, 1.547, 0.615, respectively) CONCLUSION: Although early referral decrease catheter use at the initiation and urgent hemodialysis, classical risk factors such as old age, presence of diabetes, nutritional status at the initiation are more important in patients prognosis.

OBJECTIVE: The Purpose of this study was to evaluate monochorionicity as a risk factor for adverse perinatal outcomes in spontaneously conceived twins. METHODS: Using an established database, the study included pregnant women with spontaneously conceived twin gestations between January 1998 and December 2002. From a total of 1145 twin deliveries, 371 spontaneous twin pregnancies were observed in Department of Obstetrics and Gynecology in Samsung Cheil Hospital and Women's Healthcare Center. Chorionicity was established by histologic examination and divided into two groups, monochorionic (diamnionic and monoamnionic) twins (MC) and dichorionic diamnionic twins (DC). The obstetric and neonatal outcomes were compared between the two groups. RESULTS: There were 176 MC and 195 DC twin deliveries following natural fertilization. The incidence of intrauterine growth restriction was significantly higher (16.4% vs. 5.4%, P<.001) in MC twins. However, there were no statistically significant differences in the frequency of antepartum or intrapartum complications such as preterm delivery, preeclampsia, placenta previa and gestational diabetes mellitus between the two groups. In addition, there were no statistically significant difference in the frequency of neonatal complications, congenital anomalies, Apgar scores, perinatal mortality, morbidity and duration of neonatal intensive care unit admission. CONCLUSION: When compared with DC twin group, MC twin group is more likely to have a higher incidence of intrauterine growth restriction in natural fertilization. However, monochorionicity is not a risk factor for adverse obstetric outcomes, perinatal mortality and morbidity in spontaneously conceived twins in our study.

OBJECTIVE: To evaluate planned pregnancy rate and associated factors related planned pregnancy. METHODS: We surveyed 1,396 cases from May 2002 to December 2002. The cases were derived from the Maternity school. They filled out questionnaire including planned pregnancy, medico-social-economic status. Then, we assessed the planned pregnancy rate with associated medico-social-economic state, through the prospective study. RESULTS: The planned pregnancy rate is 51.4%. The major factor which affected the planned pregnancy rate is the income of the family. The association with the planned pregnancy rate and the parity, age, and educational attainment of the women are not statistically significant. In unplanned group, exposure to alcohol, X-ray and medication is significantly increased in early pregnancy. CONCLUSION: The planned pregnancy can prevent induced abortion and reduce the birth defects due to early exposure to teratogen. Therefore it is important to make an effort to raise the planned pregnancy rate.

Antiviral activity against Influenza virus of 14 Lactobacillus species isolated from food was monitored. Lactobacillus species were isolated from traditional Korean fermented food. Each live Lactobacillus was administered into the nasal cavity of SPF 6-week-old BALB/c mice. After the Lactobacillus treatment, Influenza virus (A/NWS/33/H1N1) was inoculated to each mouse. Clinical signs and mortality was monitored for 21 days. Each Lactobacillus strain showed various level of antiviral activity against Influenza virus. As a result of this study, this mouse experiment model, including intranasal treatment of live Lactobacillus species, could be effective model in evaluating immunomodulatory response of probiotics against respiratory viruses.
