PURPOSE:Recent studies proposed that polyunsaturated fatty acids (PUFA) of the omega6 series (linoleic acid, LA) compared to the omega 3 series (linolenic acid, LNA) may be a potent promoters of adipogenesis during the gestation/lactation period. Increased ratio of LA/LNA may stimulate adipose tissue development during gestation/lactation period and may subsequently lead to chilhood obesity. The purpose of this study is to evaluate fatty acids composition of the breast milk in Korean lactating women and to analyze the relationship between LA/LNA and the body weight gain of the infants. METHODS:Fifty eight healthy postpartum lactating women and their healthy 58 breast feeding infants were studied. At 11.3+/-3.9 days of postpartum, breast milk were taken and analyzed by gas-liquid chromatography with one-step methylation method. RESULTS:The total fat contents in breast milk were 3.2+/-1.3%. The total fat contents in breast milk were not related to maternal BMI or Kaup index of infants. The percentage of PUFA was 24.9+/-6.0%. Among these PUFA, the percentage of LA and LNA was 20.3+/-5.8% and 2.2+/-0.8%, respectively. LA/ LNA ratio was 10.2+/-2.5. There were no significant correlations between LA/LNA ratio and infant weight gain during the first 2 months of life. CONCLUSION: Short term weight gain of infant was not related to the LA/LNA ratio in the breast milk. Further studies on the long term effects on fat percent and body weight of infants would be needed.

3-Methylcrotonyl-CoA carboxylase(MCC) is a biotin-dependent enzyme involved in the leucine metabolism. We describe a patient with MCC deficiency who manifested with Reye syndrome-like illness with status epilepticus, metabolic acidosis, hypoglycemia, hyperammonemia, elevated liver enzymes and neurologic impairments after a viral gastroenteritis and then suffered from Lennox-Gastaut syndrome. Urinary organic acid analysis revealed increased excretions of 3-hydroxyisovaleric acid and 3-methylcrotonylglycine. This patient was managed with a leucine restriction diet and supplementation of biotin and carnitine, which was not so effective. He suffered from neurologic sequelae such as Lennox-Gastaut syndrome, motor and cognitive impairements.

PURPOSE: To evaluate the patterns of preoperative pulmonary function tests(PFTs) and their correlation with postoperative pulmonary impairment in patients with adolescent idiopathic scoliosis(AIS), who had orthopaedic operation with or without rib resection thoracoplasty. METHODS: The case records and radiographs of 79 patients(12, boys and 67, girls) of a mean age of 13.3 years(7-15 years) with AIS who underwent orthopaedic operations at the author's institute between 1997 and 2003 were reviewed. RESULTS: The average preoperative coronal Cobb measurement was 56 (range, 32-81 ). Thirty-one patients(39%) had normal values of of PFTs. Forty five patients(57%) with severe scoliosis(Cobb's angle 65-90 ) showed mild to moderate decrease on PFTs with FVC(73%), FEV1(79%), FEV25-75%(58 %). The severity of Cobb's angle were correlated with the decrease in FVC, FEV1, FEV25-75%(P< 0.05). Forty-three patients had thoracoplasty. Twenty-two(51%) of them had pleural effusions. Eleven patients among them had chest tube inserted postoperatively. But, none of the patients had any increased requirement of postoperative ventilatory support. The incidence of postoperative pulmonary effusion in patients with thoracoplasty was a 17-fold increase, compared to the patients without thoracoplasty(O.R.=17, chi-squared-test, P<0.05). CONCLUSION: The fall in FVC and FEV1 of patients with mild to moderate scoliosis(Cobb's angle, below 65 ) was mild and was unlikely to be of clinical significance. It appeared that patients with severe AIS had mild to moderate restrictive patterns with reduced lung volumes. Performance of the thoracoplasty was the important risk factor for postoperative pulmonary complications in patients underwent surgical operation.

We observed a very rare case of primary lung cancer producing alpha-fetoprotein (AFP). A 70-year-old male with a history of smoking 50 packs per year was diagnosed with large cell carcinoma of the lung. The clinical stage was T2bN3M0 (IIIB), and serum AFP was 23,247 ng/mL. There was no evidence of metastasis to the liver, scrotum or other organs. While undergoing chemotherapy for 1 year, as the cancer progressed the AFP value steadily increased. The patient died of respiratory failure due to pneumonia 12 months after being diagnosed with lung cancer.

A 5-year-old Korean boy was admitted with dyspnea, intermittent cyanosis and finger clubbing. He was diagnosed to be suffering measles pneumonia 3 years ago. Plain radiograph showed collapse of the right lung, mediastinal shifting and infiltration on both lower lung fields. High resolution computerized tomography revealed a central bronchiectasis with mosaic hyperinflation. All of the clinical information indicated that the severity of illness score was 4 of bronchiolitis obliterans (BO). The bronchoalveolar lavage cellular profile showed predominant neutrophilia. BO with finger clubbing has been rarely reported previously in childhood. We report a case of BO with finger clubbing in children with regard to clinical presentation of measles complicated pneumonia.

Paragonimiasis is an infectious disease caused by consumption of raw or improperly cooked freshwater crab or crayfish contaminated with Paragonimus metacercariae. The incidence of the disease has markedly decreased, but it is still a lung disease that requires a differential diagnosis in endemic areas such as Korea and Japan. It is commonly found in the lung but has also been found as extrapulmonary infestations, such as cerebral, spinal, subcutaneous, abdominal, urinary, and gynecological infestations. We report a rare case of ectopic paragonimiasis involving the breast with pleural effusion that was initially misdiagnosed as tuberculous pleurisy and a breast abscess.

PURPOSE: To determine the usefulness of carbon dioxide(CO2) indirect portography during TIPS procedure. MATERIALS AND METHODS: We evalvated eight patients who had undergone TIPS due to variceal hemorrhage or ascites caused by portal hypertension. All patients but one with complete situs inversus underwent wedged right hepatic venography for visualization of the portal vein using CO2. For CO2 indirect portal venography, 50cc of CO2 was injected by hand without prior injection of a small amount of CO2. In three patients a 5-F angiographic catheter was wedged into the right hepatic vein, and in the other five a 9-F sheath from a Ring 's transjugular access set was adjunctively wedged into the right hepatic vein over the 5-F catheter. The time required for portal vein puncture was defined as the time between the indirect portal venography procedure and the first procedure after successful portal vein puncture. RESULTS: All patients successfully underwent TIPS without any immediate complication. The portal vein was visualized by CO2 in 7 of 8 patients (87.5 %). Two of three patients who underwent indirect portography with only a 5-F catheter wedging demonstrated opacification of the right portal vein; in the remaining patient the portal venous system was not visualized. Of the five patients who underwent indirect portography with an adjunctive 9-F sheath wedged in the right hepatic vein, four showed opacification from the peripheral to the main portal vein, and in the other, the only right peripheral portal vein was opacified. The mean time for portal vein puncture was 20.5 minutes. CONCLUSION: For visualization of the portal venous system during TIPS procedure, the use of CO2 indirect portography is feasible.

Citrobacter species is a gram-negative bacilli that can cause opportunistic infections in immunocompromised hosts. Citrobacter braakii refers to the genomospecies 6 of the Citrobacter freundii complex. There are no detailed studies on infections caused by this newly identified specific genetic species in Korea. We herein report a case of a patient with hepatocellular carcinoma who, after undergoing transcatheter arterial chemoembolization, developed biloma which later progressed to C.braakii sepsis and did not respond to treatment. To our knowledge, this is the first reported case in Korea on C. braakii infection resulting in septic shock in a patient with malignancy in Korea.

BACKGROUND: Despite major progress in stem cell therapy, our knowledge of the characteristics and tissue regeneration potency of long-term transported cells is insufficient. In a previous in vitro study, we established the optimal cell transport conditions for amniotic fluid stem cells (AFSCs). In the present study, the target tissue regeneration of long-term transported cells was validated in vivo. METHODS: For renal regeneration, transported AFSCs were seeded on a poly(lactide-co-glycolide) scaffold and implanted in a partially resected kidney. The target tissue regeneration of the transported cells was compared with that of freshly harvested cells in terms of morphological reconstruction, histological microstructure reformation, immune cell infiltration, presence of induced cells, migration into remote organs, expression of inflammation/fibrosis/renal differentiation-related factors, and functional recovery. RESULTS: The kidney implanted with transported cells showed recovery of total kidney volume, regeneration of glomerular/renal tubules, low CD4/CD8 infiltration, and no occurrence of cancer during 40 weeks of observation. The AFSCs gradually disappeared and did not migrate into the liver, lung, or spleen. We observed low expression levels of proinflammatory cytokines and fibrotic factors; enhanced expression of the genes Wnt4, Pax2, Wt1, and Emx2; and significantly reduced blood urea nitrogen and creatinine values. There were no statistical differences between the performance of freshly harvested cells and that of the transported cells. CONCLUSION: This study demonstrates that long-term transported cells under optimized conditions can be used for cell therapy without adverse effects on stem cell characteristics, in vivo safety, and tissue regeneration potency.
