PURPOSE: We investigated the clinical course of infants with congenital heart disease (CHD) who experienced thyroid dysfunction within 100 days of birth. METHODS: We performed retrospective medical reviews of 54 CHD patients (24 male patients) who underwent a thyroid function test (TFT) between January 2007 and July 2016. Data were collected on birth history, diagnosis of CHD, underlying chromosomal or genetic abnormalities, medication history, surgery, ventilator care, and exposure to iodine contrast media (ICM). Results of neonatal screening tests (NSTs) and TFTs were reviewed. RESULTS: A total of 36 patients (29 transient, 7 permanent) showed thyroid dysfunction. Among the seven patients with permanent hypothyroidism, three had an underlying syndrome, three showed abnormal NST results, and one was admitted to the intensive care unit for macroglossia and feeding cyanosis. We found that infants with transient thyroid dysfunction had a lower birth weight and were more commonly exposed to thyroid disrupting medication and/or ICM. However, these risk factors were not significant. A total of 8 patients with a history of ICM exposure showed thyroid dysfunction. Excluding 3 patients with elevated thyroid stimulating hormone before ICM exposure, 5 patients recovered from transient thyroid dysfunction. CONCLUSIONS: We observed thyroid dysfunction in two-thirds of CHD infants (53.7% transient, 13.0% permanent) who had risk factors and received TFT screening within 100 days, despite normal NSTs. Further studies with larger sample sizes are required to revise the criteria for TFT screening in CHD infants.

PURPOSE: We wanted to evaluate the cerebral metabolites in patients with chronic renal failure (CRF) and who were undergoing hemodialysis by performing proton MR spectroscopy and we wanted to evaluate the correlation between the changes in the cerebral metabolite ratios and the duration after starting the initial hemodialysis. MATERIALS AND METHODS: Proton MR spectroscopy was performed in 15 patients with CRF and who were undergoing hemodialysis and in ten healthy volunteers. The changes in N-acetylaspartate (NAA), choline-containing compounds (Cho), myo-inositol (Myo), glutamine/glutamate complex (Glx), and creatine (Cr) were analyzed. MR spectroscopy was performed before and after hemodialysis. RESULTS: For the patients with CRF before hemodialysis, the Cho/Cr ratio in the gray matter (p<0.001) and the Myo/Cr ratio in both the gray and white matter (p<0.01) were significantly elevated compared with those in the control subjects. For the patients with CRF after hemodialysis, their Cho/Cr ratios were significantly reduced in both the gray and white matter compared with that before hemodialysis (p<0.05). There was a significant positive correlation between the Cho/Cr ratio and serum Cr in the gray matter of CRF patients after hemodialysis (r=0.54, p<0.05). The cerebral metabolite ratios were not significantly correlated with the duration after starting the initial hemodialysis. CONCLUSION: The cerebral metabolite patterns are significantly different between the patients with CRF and who are undergoing hemodialysis and the normal controls. The cerebral metabolite ratios are not significantly correlated with the duration after starting the initial hemodialysis.

The biological interpretation of two-dimensional (2D) gel electrophoresis experiments is a key step toward understanding the functions of biological systems. We here present a web-based integrated database, called 2DSpotDB, for the management of proteome data derived from several pathogens. The 2DSpotDB was established as a part of the management of a pathogen proteome project at the Korea National Institute of Health. The goals of the 2DSpotDB implementation are to store and define important pathogen genes, retrieve information obtained by 2D polyacrylamide gel electrophoresis and mass spectrometry, and create an integrated system to provide pathogen proteome information for biological scientists. This database currently contains 14 gels and information on 387 protein spots, among which 329 proteins were identified and annotated.

Balloon dilatation has been applied in treatint of various pathologic narrowing of the hollow viscus. It is now accepted as very effective modality especially in treating esophageal stenosis obviating surgical procedure. We performed 128 balloon dilatations in 29 patients with the number of dilatations in each patient ranging from once to 12 times. The age distribution of the patients was from 3 weeks to 6 years, with the median age of 3 months. Twenty nine patients consisted of 25 postoperative esophageal strictures (21 esophageal atresia with tracheoesophageal fistula, 1 congenital esophageal stenosis, 2 tracheobronchial remnant, and 1 congenital esophageal stenosis with esophageal atresia), 2 achalasia, 1 congenital esophageal stenosis, and 1 corrosive esophagitis. We had successful dilation in 22 patients, who showed subsequent relief of symptoms and improvement in the diameter of stenotic segment. In 4 patients, esophageal perforation occurred during the procedure, one requiring emergency thoracotomy and the other threeconservative management. Seven patients had no improvement in stenotic sites after several balloon dilatations. Failed cases were congenital stenosis, achalasia, corrosive esophagitis and four postoperative strictures. We believe that balloon dilatation is the procedure of choice in the treatment of postoperative esophageal stricture in infants and children and is a safe method as the perforation which can complicate the procedure could be managed conservatively.

Intradiploic epidermoid cysts, like epidermoid cysts in other cranial locations, are rare. Approximately 100 intradiploic epidermoids have been reported, involving all of the cranial bones in proportion to their relative sizes1). Over half erode through both tables of the cranium, creating variably sized areas of unprotected brain beneath the soft tumor. We report a case of an intradiploic epidermoid cyst of the right parietal bone that was found after minor head trauma.

A narrow internal auditory canal (IAC) with duplication is a rare anomaly of the temporal bone. It is associated with congenital sensorineural hearing loss. Aplasia or hypoplasia of the vestibulocochlear nerve may cause the hearing loss. We present an unusual case of an isolated narrow IAC with duplication that was detected by a CT scan. In this case, the IAC was divided by a bony septum into an empty stenotic inferoposterior portion and a large anterosuperior portion containing the facial nerve that was clearly delineated on MRI.

Chylous leakage is an extremely rare complication of surgery for breast cancer. We experienced a case of chylous leakage after axillary lymph node dissection. A 38-year-old woman with invasive ductal carcinoma in the left breast underwent a modified radical mastectomy after four cycles of neoadjuvant chemotherapy. The postoperative serosanguinous drainage fluid became "milky" on the fourth postoperative day. After trying conservative management, we re-explored the axilla and ligated the lymphatic trunk. Although the success of many cases supports conservative management, timely surgical intervention represents an alternative in cases where leakage persists or where the output is high.
