Truncus arteriosus is characterized by a single arterial vessel arising from the base of the heart and giving origin to the systemic, pulmonary and coronary circulation. To evaluate the incidence, types, and associated anomalies, 18cases of truncus arteriosus diagnosed by angiocardiography, were reviewed and were compared with other reports. Ten of them were confirmed by operation. The overall incidence of truncus arteriosus was 0.127%. Accordin to Collett and Edwards classification. Type I was encountered in 11cases(61%), type II in 4cases(22%), and type III in 3cases(17%), All the patients had subtruncal ventricular septal defects. Eight patients showed truncal valve regurgitation and valve stenosis was noted in one case. A right aortic arch was present in 9 cases. Associated anomalies were atrial septal defect(8cases), patent ductus arteriosus(3cases), coarctation of the aorta(2cases), isolation of the left subclavian artery(2 cases), and right aortic arch with an aberrant left subclavian artery(1case). Truncus arteriosus is an uncommon congenital cardio vascular malformation. In the group of cases which we encountered, type I was the most common anomaly. Frequently associated anomalies were right aortic arch, incompetent truncal valve and atrial septal defect.

We report a case of ciliated hepatic foregut cyst which was incidentally found in a 64 year-old man. The cyst, 6 cm in diameter, was unilocular, solitary and was located in the medial segment of left lobe, just below the Glisson's capsule. Microscopically, the cyst wall consisted of 4 layers; pseudostratified ciliated columnar epithelium, subepithelial loose connective tissue, smooth muscle bundles and an outermost fibrous capsule. Although cartilage or subepithelial sero-mucous glands were absent, the morphologic features of the cyst correspond with those of an incomplete form of brochogenic cyst.

Fibrotic lesions occurring in the corpus cavernosum are usually cases of Peyronie's disease that originate from the tunica albuginea, or they are the fibrotic result of inflammatory processes. The lesion involving the corpus cavernosum, but not tunica albuginea is rare. We present here a case of fibrotic nodule arising in the corpus cavernosum with the sonographic and magnetic resonance imaging features. A 38-year-old man complained a small nodular mass in the left corpus cavernosum at the level of penoscrotal junction without abnormal curvature of the organ. We performed ultrasonography and magnetic resonance imaging to determine exactly what the lesion was. The lesion was removed and it was pathologically found to be a localized fibrotic nodule of the corpus cavernosum with some narrow-channeled vascular structures.

BACKGROUND: In anesthesia for cesarean section, thiopental sodium is regarded as the standard induction agent. Propofol, 2,6 di-isopropyl phenol, is a relatively new intravenous anesthetic agent and has been used for induction and maintenance of general anesthesia or total intravenous anesthesia. Propofol has properties which suggest that it might be useful alternative to thiopental. METHODS: Forty patients (ASA physical status 1,2) scheduled for cesarean section were randomized to either propofol (n=20) or thiopental group (n=20). In thiopental group anesthesia was induced with thiopental 4-5 mg/kg intravenously and maintained by inhalation of enflurane and nitrous oxide. In propofol group anesthesia was induced with propofol 2 mg/kg intravenously and maintained by continuous infusion of propofol 6-10 mg/kg/hr and inhalation of nitrous oxide. RESULTS: Systolic and mean arterial pressure were increased significantly in both groups at 1 min after intubation, but degree of increase were less in propofol group. There was no significant difference in diastolic pressure in both groups. Heart rate was increased significantly in both groups at afterinduction, but degree of increase were less in propofol group. The Apgar scores of the neonates and blood gas analyses of umbilical vein were not significantly different in both groups. Maternal recovery from anesthesia was quicker in propofol group. CONCLUSIONS: A propofol infusion coupled with nitrous oxide was proved to be clinically satisfactory anesthesia for cesarean section with no adverse effect on both mother and fetus. Conclusively, propofol would be an excellant alternative to thiopental sodium and inhalation anesthetic in general anesthesia for cesarean section.

Dermatomyositis is characterized by progressive, symmetric, proximal muscle weakness and a nonsuppurative inflammatory myopathy of unknown etiology involving predominantly skeletal muscles. It is also characterized by typical skin lesions. Interstitial lung disease has a poor prognosis when it is associated with dermatomyositis. Organizing pneumonia is a disease in which granulation tissue fills the lumina of terminal and respiratory bronchioles and extends into the distal airspaces. The cryptogenic nature of the process is appreciated in that organizing pneumonia patterns of injury can be seen in secondary forms of the disease (secondary organizing pneumonia). Organizing pneumonia has been reported to occur in 5~10% in dermatomyositis-polymyositis patients. Anti-histidyl tRNA synthetase antibody (anti-Jo-1) is a predictive disease marker that is reported to occur in up to 70% of patients. We describe a 49-year-old male dermatomyositis patient who presented with organizing pneumonia and was found to have negative anti-Jo-1 antibody.

BACKGROUND: Foremost fine hairs in the frontal hairline region are critical in hair transplantation for hairline correction (HTHC) in women. However, there are few studies on a nonsurgical revisionary method for improving an unnatural foremost hairline with thick donor hairs resulting from a previous HTHC. OBJECTIVE: To investigate the efficacy and safety of using a hair removal laser (HRL) system to create fine hairs in Asian women with thick donor hairs. METHODS: Through a retrospective chart review, the HRL parameters, hair diameter (measured with a micrometer before and after the procedures), subjective results after the procedures, adverse effects, and the number of procedures were investigated. The reduction rate of the hair diameter was calculated. RESULTS: Twenty-four women who received long-pulse Neodymium-Doped:Yttrium Aluminum Garnet therapy after HTHC were included. The parameters were as follows: delivered laser energy, 35~36 J/cm2; pulse duration, 6 ms; and spot size, 10 mm. The mean number of laser sessions was 2.6. The mean hair diameter significantly decreased from 80.0+/-11.5 microm to 58.4+/-13.2 microm (p=0.00). The mean rate of hair diameter reduction was -25.7% (range, -44.6% to 5.7%). The number of laser sessions and the hair diameter after the procedures showed a negative correlation (r=-0.410, p=0.046). Most of the patients (87.5%) reported subjective improvement of their hairlines. Most complications were transient and mild. CONCLUSION: HRL can be an alternative method for creating fine hairs and revising foremost hairline in Asian women with thick donor hairs.

BACKGROUND/AIMS: Gout is a common inf lammatory arthritis triggered by the crystallization of uric acid in the joints. Serum uric acid levels are highly heritable, suggesting a strong genetic component. Independent studies to confirm the genetic associations with gout in various ethnic populations are warranted. We investigated the association of polymorphisms in the ABCG2 and SLC2A9 genes with gout in Korean patients and healthy individuals. METHODS: We consecutively enrolled 109 patients with gout and 102 healthy controls. The diagnosis of gout was based on the preliminary criteria of the America College of Rheumatology. Genomic DNA was extracted from whole blood samples. We identified single nucleotide polymorphism (SNP) changes in the ABCG2 and SLC2A9 genes using a direct sequencing technique. rs2231142 in ABCG2 and rs6449213 and rs16890979 in SLC2A9 and nearby regions were amplified by polymerase chain reaction. RESULTS: Patients with gout had significantly higher A/A genotype (29.3% vs. 4.9%, respectively) and A allele (52.8% vs. 26.5%, respectively) frequencies of rs2231142 in ABCG2 than did controls (chi2 = 29.42, p < 0.001; odds ratio, 3.32; 95% confidence interval, 2.11 to 5.20). We found novel polymorphisms (c.881A>G and c.1002+78G>A) in the SLC2A9 gene. The univariate logistic regression analysis revealed that the c.881A>G and c.1002+78G>A SNPs were significantly higher in patients than in controls. CONCLUSIONS: We demonstrated a significant association between rs2231142 in the ABCG2 gene and gout and identified novel SNPs, c.881A>G and c.1002+78G>A, in the SLC2A9 gene that may be associated with gout in a Korean population.
