PURPOSE: Pneumonia is a common complication of organophosphate poisoning and increases the incidence of respiratory failure and the duration of mechanical ventilator support. Therefore, we investigated the clinical characteristics of pneumonia as a complication of organophosphate insecticide poisoning and then determined the factors related to the development of pneumonia. METHODS: A retrospective study was performed on patients with organophosphate insecticide poisoning, who were treated at our hospital with medical records and chest radiograph of patients. From January 1, 2001, to July 31, 2004, eighty five patients were included in this study. RESULTS: 1) Thirty-two (71% of the patients developing pneumonia) patients developed pneumonia later than 48 hours from admission and twenty-five (55.6% of the patients developing pneumonia) patients developed pneumonia later than 48 hours after mechanical ventilatory support. 2) The mean onset of pneumonia resistant to initial empirical antibiotics was 4.8 days from admission, and that of susceptible pneumonia was 3.7 days from admission. 3) Patients with pneumonia as a complication needed larger doses of atropine and more 2-pralidoxime injections, as well as longer mechanical ventilatory support, ICU admission, and total hospital admission. CONCLUSION: Most Pneumonia in organophosphate poisoning patients were nosocomial pneumonia & ventilator-associated pneumonia. Thus, to reduce the incidence of pneumonia complication in organophosphate poisoning patients, Physicians must take measures, such as hand-washing and careful periodic drainage of tubing condensate, etc., to reduce the incidence of nosocomial pneumonia. In selecting empirical antibiotics for pneumonia complicating organophosphate poisoning patients, physicians should take regional prevalence of nosocomial pathogens into consideration. In late-onset ventilator-associated pneumonia, physicians must consider pneumonia caused by organisms resistant to commonly used empirical antibiotics.

Rheumatic fever with renal involvement is rarely seen. The prevalence is found to be low although it may differ by reporters. We report a case of rheumatic fever with IgA nephropathy. The patient was a 14-year-old male. The patient's chief complaint were fatigue and gross hematuria. On the physical examination, the pansystolic murmur (grade II) on the left lower sternal border was noted. Cardiomegaly was seen on chest X-ray and pulmonary vasculatures were increased. Prolonged PR intervals were found on EKG. Echocardiogram showed rheumatic carditis with grade mild to moderate MR, regurgitant shunt from LV to LA through anterior leaflet. On the laboratory findings, ESR, CRP and ASO were increased, C3, C4 and IgA were normal. On the urine analysis, gross hematuria was noted as RBC over 30/HPF and RBC dysmorphism 90%. On the immunofluoroscent microscope of renal biopsy, IgA deposit on mesangial matrix was noted.

To determine whether age, weight, height, vertebral column length, body mass index, or abdominal circumference might influence the distribution of sensory analgesia after epidural anesthesia, 100 women presenting for cesarean section were studied. All received 26 mg of 2.0% lidocaine mixed with 8.4% bicarbonate 1 ml/lidocaine 10 ml and 1:300,000 epinephrine, including 3 ml of test dose, through the epidural catheter inserted in L3-4 interspace. While the women lay supine on a horizontal operating table with the air bag under their right hip, 2, 5, 10, 20, and 30 minutes after injection, the cephalad extent of sensory analgesia (loss of sensation of sharpness to pin prick) was determined. Age (31.9+/-3.8 years), weight (69.2+/-9.3 kg), height (158.9+/-4,5 cm), vertebral column length (59.8+/-5.0 cm), body mass index (27.4+/-3.2 kg/m(2)), and abdominal circumference (103.5+/-10.2 cm) did not correlate with the maximum level of sensory analgesia. In conclusion, in parturients of age, weight, height, vertebral column length, body mass index and aMominal circumference of the above values, it is not necerrary to vary dose of injected local anesthetics with changes in any of the patient variables studied.

OBJECTIVES: This study was carried out to establish human embryonic stem cells derived from frozen-thawed embryos using mouse embryonic fibroblasts (mEFs), human fetal skin and muscle fibroblasts as feeder cells, and to identify the characteristic of embryonic stem cells. METHODS: When primary mEFs, human fetal skin and muscle fibroblasts were prepared, passaging on 4 days from replating could have effective trypsinization and clear feeder layers. Eight of 23 frozenthawed 4~8 cell stage embryos donated from consenting couples developed to blastocysts. Inner cell mass (ICM) was isolated by immunosurgery. ICM was co-cultured on mEFs, human fetal skin or muscle fibroblasts. The ICM colonies grown on mEFs, human fetal skin or muscle fibroblasts were tested the expression of stage specific embryonic antigen-3, -4 (SSEA-3, -4), octamer binding transcription factor-4 mRNA (Oct-4) and alkaline phosphatase surface marker. RESULTS: We obtained 1 ICM colony from 2 ICM co-cultured on mEFs as feeder cells and did not obtain any ICM colony from 6 ICM clumps co-cultured on human fetal skin or muscle fibroblasts. The colony formed on mEFs could be passaged 30 times every 5 days with sustaining undifferentiated colony appearance. When the colonies cultured on mEFs were grown on human fetal skin or muscle fibroblasts, the colonies could be passaged 15 times every 9 days with sustaining undifferentiated colony appearance. The colonies grown on mEFs and human fetal fibroblasts expressed SSEA-4 and alkaline phosphatase surface markers and positive for the expression of Oct-4 by reverse transcription-polymerase chain reaction (RT-PCR). The produced embryoid body differentiated spontaneously to neural progenitorlike cells, neuron-like cells and beating cardiomyocyte-like cells, and frozen-thawed embryonic stem cells displayed normal 46, XX karyotype. CONCLUSIONS: The human embryonic stem cells can be established by using mEFs and human fetal fibroblasts produced in laboratory as feeder cells.

BACKGROUND AND OBJECTIVES: Although electrical cardioversion (CV) is effective in restoring sinus rhythm (SR) in patients with atrial fibrillation (AF), AF frequently recurs in spite of antiarrhythmic medications. We investigated the predictors of failed CV and AF recurrence after successful CV. SUBJECTS AND METHODS: In 81 patients (M:F=63:18, 59.1+/-10.5 years old) with AF who underwent CV, clinical findings and pre-CV serologic markers were evaluated. RESULTS: During 13.1+/-10.6 months of follow-up, 8.6% (7/81) showed failed CV, 27.16% (22/81) showed early recurrence atrial fibrillation (ERAF; < or =2 weeks), 32.1% (26/81) had late recurrence atrial fibrillation (LRAF; >2 weeks), and 32.1% (26/81) remained in SR and had no recurrence (NR). Plasma levels of transforming growth factor beta (TGF)-beta were significantly higher in patients with failed CV than in those with successful CV (p=0.0260). Patients in whom AF recurred were older (60.4+/-9.0 years old vs. 55.3+/-12.5 years old, p=0.0220), and had lower plasma levels of stromal cell derived factor (SDF)-1alpha (p=0.0105). However, there were no significant differences in these parameters between ERAF patients and LRAF patients. CONCLUSION: Post-CV recurrence commonly occurs in patients aged >60 years and who have low plasma levels of SDF-1alpha. High plasma levels of TGF-beta predict failure of electrical CV.

Klinefelter's syndrome (KFS) is a gonosomal aberration disease that occurs in males, and is characterized by 47, XXY karyotype, hypogonadism and a lack of secondary sexual characteristics. A potential link between this hormonally deficient syndrome and autoimmune disease, particularly systemic lupus erythematosus (SLE), has been reported. On the other hand, KFS is rarely reported to be accompanied by rheumatoid arthritis (RA), and there are no Korean cases reported. We report the first Korean case of a KFS patient with sero-positive RA and discuss the role of the pathogenesis of RA with KFS.

BACKGROUND: The single-breath carbon monoxide diffusion capacity (DLCO) and the per unit alveolar volume (KCO; DLCO/VA) gave discordant values when there was an abnormal alveolar volume (VA). However, the clinical significance of the discordant values in patients with airflow limitation has not been examined. This study investigated the DLCO and KCO changes after improving the airflow limitation. METHOD: The baseline DLCO and KCO with lung volume were measured in patients with an airflow obstruction. The effective alveolar volume was measured using the single-breath CH4 dilution method. The patients divided into two groups according to the baseline values: (1) increased KCO in comparison with the DLCO (high discordance) (2) decreased or not increased KCO in comparison with the DLCO (low discordance). The diffusion capacity and lung volume were measured after treatment. RESULTS: There was no significant difference in the baseline lung volumes including the FEV1 and FVC between the two groups. The FEV1 and FVC were significantly increased in the high discordance group compared with the low discordance group after treating the airflow limitation. The DLCO and alveolar volume were significant higher in the high discordance group compared with the low discordance group while the TLC was not. CONCLUSION: The discordance between the DLCO and KCO could be translated into an airflow reversibility in patients with an airflow limitation

PURPOSE: To evaluate the results of five-pin external fixation, with the fifth pin stabilizing the distal radius articular fragment, for unstable distal radial fractures. MATERIALS AND METHODS: Twenty cases of unstable distal radial fractures were treated with five-pin external fixation (5-pin group). The fifth pin was inserted into the distal articular fragment and attached to the external fixation frame. Metacarpal pins were removed at sixth week in 12 cases and at third in 8 cases, and radial pins were removed at eighth or ninth week. The radiographic results of 5-pin group were compared with those of 20 cases of traditional four-pin external fixation (4-pin group). RESULTS: The postoperative radial inclination was 23.1 degrees in 5-pin group and 22.2 degrees in 4-pin group; while at last follow-up 21.8o and 15.1 degrees respectively. Postoperative volar tilt was 8.5 degrees and 7.3o; while at last follow-up 6.3 degrees and 0.1 degrees respectively. Postoperative radial shortening was 0.3 mm, 0.4 mm; while at last follow-up 1.1 mm and 2.1 mm respectively. In 5-pin group, there were no significant differences in results whether the metacarpal pins were removed at sixth or third week. CONCLUSION: Five-pin external fixation, with the fifth pin stabilizing the distal articular fragment, enhanced early motion of the wrist maintaining fracture stability in unstable fractures of the distal radius.
