BACKGROUND: Our purpose was to assess the utility of prenatal triple-marker (alpha- fetoprotein (AFP), beta-human chorionic gonadotropin (hCG) and unconjugated estriol (uE3) testing for chromosomal abnormalities in women with Down syndrome screen-positive results. METHODS: Total 1,082 women between 15 and 21 weeks' gestation received second trimester Down syndrome risk evaluation by triple marker testing. AFP, beta-hCG and uE3 were measured by Coat-A-Count(R) IRMA (Diagnostic Products Corporation, LA, USA), The risk for Down syndrome was calculated using a commercially available software program (AFP Expert; Benetech Medical System, Toronto, Canada) by use of a Down syndrome risk cutoff value(1:270 at midtrimester). Karyotypes were reviewed for 32 (54.2%) of these patients who received prenatal chromosome analysis. RESULTS: Fifty nine (5.5%) patients of the 1,082 women screened were identified as positive. Two chromosome abnormalities (47,XYY and 46,XX, int (9) ) were found in the 32 patients who underwent prenatal chromosome analysis (6.3%). Any cases on the abnormal serum tests torn out not to be associated with trisomy 21. CONCLUSIONS: Although triple marker screen appears to be an effective method detecting chromosome abnormalities there is a high false positive rate. Therefore, new screening test that reduce false positive rate is need to be introduced.

The gene encoding F protein of CBP-1 strain, a heat-stable Newcastle disease virus (NDV) isolated from the diseased pheasants in Korea, was characterized by reverse transcription-polymerase chain reaction (RT-PCR), nucleotide and amino acid sequences. Virus RNA was prepared from the chorioallatoic fluid infected with NDV CBP-1 virus and cDNA was amplified by RT-PCR, cloned and sequenced to analyze. The PCR was sensitive as to detect the virus titer above 25 hemagglutination unit. 1.7kb (1,707bp) size of the cDNA was amplified and cloned into BamHI site of pVL1393 Baculo transfer vector. The nucleotide sequences for F protein were determined by dye terminator cyclic sequencing using four pairs of primers, and 553 amino acid sequences were predicted. In comparison of the nucleotide sequence of F gene of CBP-1 with those of other NDV strains, the homology revealed 88.8%, 98.5% and 98.7% with Kyojungwon (KJW), Texas GB and Beaudette C strains, respectively. As the deduced 553 amino acid sequences of F protein of CBP-1 were compared with those of other NDV strains, the homology appeared 89.9%, 98.7% and 98.9% with KJW, Texas GB and Beaudette C strains, respectively. The putative protease cleavage site (112-116) was R-R-Q-K-R, indicating that CBP-1 strain is velogenic type. The amino acid sequences include 6 sites of N-asparagine-linked glycosylation and 13 cysteine residues. These data indicate that the genotype of CBP-1 strain is more closely associated with the strains of Texas GB and Beaudette C than KJW strain.

Meibomian gland adenocarcinoma is a rare neoplasm which may be overlooked until it spreads into the orbit. We have experienced a case of meibomian gland adenocarcinoma which spread into the orbit, and performed orbital exenteration. Two months later, the patient had a recurrence at the superolateral margin of the orbit that surgically excised. The radiation therapy with total dose of 5000 rads over a period of one month was performed and the tumor mass was regressed. There was no evidence of recurrence at 12 months after radiation therapy.

We report two patients with Hallervorden-Spatz disease, who were diagnosed by same MR findings of marked low signal intensity in the globus and substantia nigra. They presented with ataxic and spastic gait, intention tremor, delayed mental development, and dysarthria. They were 7 year-old male and 8 yea r-old female siblings, who were healthy until 3 years of age when they suffered from progressive symptoms. T2-weighted images showed marked low signal intensity in the globus pallidus and substantia nigra indicating an increased irondeposition, and it might suggest Hallervorden-Spatz disease.

Acrodermatitis enteropathica(AE) which starts in early infancy after weaning is a rare hereditary chronic disorder of zinc absorption. AE is characterized by alopecia, diarrhea and skin lesions localized to periorificial areas and acrally on the extremities. However, recent reports presented Transient Symptomatic Zinc Deficiency(TSZD) in preterm infants. TSZD is clinically similar to AE and skin lesions rapidly heals after zinc supplementation. When the treatment was withheld, no recurrence was seen. We experienced a TSZD case in a cow's milk fed, preterm infant, so We report it with a brief review of literature.
