Neonatal urologic urgencies are any genitourinary condition during the 1st month of life that jeopardizes the gonads, the kidneys, or the life of the infant if there is a delay in either diagnosis or treatment. Since 1991, we have experienced 41 cases of neonatal urologic urgencies. Of 41 cases, 23 were detected prenatally. Male to female distribution was 29 to 12. The initial symptoms or signs at presentation were antenatal hydronephrosis in 21, fever in 10, scrotal mass in 5. The rest 5 were 1 abdominal mass, 1 cystic adrenal mass, 1 absence of kidney, 1 abnormal micturition and 1 jaundice. The final diagnosis were 1 neuroblastoma, 2 multicystic dysplastic kidney, 1 multicystic dysplastic kidney and contralateral UPJO, 2 unilateral transient hydronephrosis, 3 bilateral transient hydronephrosis, 1 unilateral renal hypoplasia and contralateral hydronephrosis, 1 unilateral and 2 bilateral UPJO, 1 renal agenesis, 5 complete duplicate ureter, 3 primary megaureter, 1 unilateral UVJ0, 2 unilateral and 9 bilateral VUR, 1 PUV, 1 congenital megalourethra with bilateral hydronephrosis, 1 acute epididymitis, 3 torsion of spermatic cord, 1 cystic teratoma. Surgical treatment was performed in 26 and conservative management in 15. Since it has been reported 2/3 of all infant deaths occur during the 1st year of life, especially most are during the neonatal period, we believe it is crucial that urologists be involved in the care of newly born infants and be alert to the clues of underlying genitourinary abnormalities or diseases because the least easily recognizable urologic abnormality may be the one that requires the most immediate attention in the neonate.

The optic canal fracture has been recognized as a clinical entity for quite sometime, and is, by no means, a rare condition. We were aware of it for last several years, and have collected five radiographically proved cases from the records. Interestingly enough, two of these patients were involved in motor-cycle accidents and revealed abrasion over the lateral end of the homolateral eye brow. Only one of these five patients had partial recovery of his vision.

The antimicrobial agents reduced infectious diseases significantly. However, antibiotic resistance has followed for almost every antimicrobial agent. Especially, Staphylococcus aureus was one of the most notorious for the multidrug resistance. Streptomyces sp. 681 has been selected for antibiotic-producing strain against methicillin-resistant Staphylococcus aureus (MRSA) from 1,000 strains of Actinomycetales which had been isolated from soil. In antimicrobial susceptibility test, all of the test strains were susceptible to vancomycin. However, most strains of Staphylococcus aureus were found to be resistant to methicillin. Ninety eight (75%) strains out of 129 strains showed multiple resistance pattern to more than 5 antimicrobial agents. The MIC values of the purified antibiotic (K-681) were 1-32 ug/ml against Gram-positive bacteria compared to >128 ug/ml against Grarn-negative bacteria or fungi. The MIC was 8 ug/ml for 90% of the 129 clinical isolates of S. aureus. The antibiotic showed no cytotoxicity against P 388, HeLa, and S180 at the concentration of 500 ug/ml.

In the present study, we investigated the differences in the levels of expression of virulence factors between blood isolates of Candida albicans and commensal strain isolated from the oral cavities of health volunteers, and correlations between virulence factors. Blood isolates of 33 and commenal isolates of 71 were characterized by putative virulence factors such as proteinase production (PROT), an ability to adhere to epithelial cells (ADH), cell surface hydrophobicity (CSH), phospholipase production (PLASE), and hyphal transition (GERM). In PROT, ADH, CSH, and PLASE, the means of expression of blood isolates were higher compared with those of commensal isolates, however statistical significance was only shown in CSH (p=0.036). On the contrary, mean expression of GERM of blood isolates was lower than that of commensal isolates. Of relationships between virulence factors, although a negative correlation of PROT with CSH was obtained, the correlation was relatively low (r=-0.316, p=0.001). These results suggest that higher expression of CSH is a more distinguishing character in virulent blood isolates of C. albicans and that the expression of virulence factors are independent.

Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

The fibrillar coat of Candida albicans is of interest as its significance in antigenicity, antiphagocytosis, and adherence to host tissues. The partial biochemical properties and ultrastructure of fibrillar coat induced by rabbit sera were examined. The induced fibrillar layer was destroyed by treatments of lyticase, proteinase K and dithiothreitol. The total protein concentration of fibrillar cell wall lysate was higher than that of non-fibrillar cell wall lysate, but the total sugar concentration was similar. On SDS-PAGE analysis, the protein profiles between in fibrillar cells and in non-fibrillar cells were shown to be different. In fibrillar cells, the major bands of cell wall lysate were 83, 66, 54, 47, 33, and 26 kDa in dithiothreitol-treated lysate. The proteins of 26 and 19 kDa were predominant in lyticase-treated lysate. Although the fibrillar thickness and protein amount of cell wall lysate were increased in according to the incubation time, the protein profiles did not changed. These results suggest that the proteins of 83, 66, 54, 47, 33, 26, and 19 kDa may be major constituents of fibrillar coat in C. albicans.

PURPOSE: This retrospective study was conducted to evaluate the value of adminstration of IV gadopentetate dimeglumine for MR imaging of tuberculous spondylitis. MATERIALS AND METHODS: The authors reviewed MR images both with and without contrast enhancement of 22 patients with tuberculous spondylitis. Evaluation of signal characteristics, enhancement patterns, and difference of delineation between pre- and postcontrast enhancement was made on 4 compartments the vertebral body, intervertebral disc, paravertebral space, and extradural space. RESULTS: The spinal tuberculous lesions revealed relatively low or isosignal intensity on T1-weighted image and high signal intensity on T2-weighted image. The tuberculous lesions of vertebral body showed enhancement of mixed pattern, and rim enhancement pattern was predominant in the other 3 compartment, suggesting abscess. The contrast enhanced MR image showed better demarcation of the extents of tuberculous lesions comparing with noncontrast image, especially at the vertebral body and intervertebral disc. The nature of tuberculous involvement was better visualized at the extradural space and paravertebral space on postcontrast image. CONCLUSION: We conclude Gd-DTPA enhanced MR image can give informations for more detailed delineation, extents, and nature of involvement in the tuberculous spondylitis.
