We have experienced a case of 13 ring chromosome in a 40-month-old girl who demonstrated psychomotor retardation with delayed speech, growth retardation, hearing loss(left), microcephaly, trigonocephaly with flat occiput, hypertelorism, epicanthal folds, microophthalmia, broad prominamt nasal bridge, high arched palate, micrognathia, large auricles and other anomalies. Cytogenetic studies of peripheral blood lymphocytes with differential staining of chromosomes revealed 46, XX, r13. Her parents' karyotypes were normal. We reported the case with the review of the associated literatures.

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

PURPOSE: To compare the efficacy and safety of ultrasound guided automated gun biopsy with fine needle aspiration biopsy of focal liver lesions. MATERIALS AND METHODS: We performed 32 automated gun(19.5G Autovac Biopsy Needle) biopsies and 27 fine needle aspiration(22G Westcott Style Biopsy Needle) biopsies in 48 patients with malignant focal liver lesion under the guidance of ultrasound. We compared the "positive for malignancy rate" and "pathologic diagnosis rate" of both methods with final diagnosis, and the rate of complications. RESULTS: The "positive for maiignancy rate" of automated gun biopsy and needle aspiration are 84.4%(27/32) and 66.7%(18/27) respectively(p=0.11). The "pathologic diagnosis rate" are 84.4%(27/32) and 55.6%(15/27) with significant statistical difference(p<0.05). And there is no difference of the rates of significant complications. CONCLUSION: When compared with the fine needle aspiration biopsy, ultrasound-guided automated gun biopsy is safe and more effective method for malignant focal liver lesion.

The purpose of this study was to perform the radiographic measurements and temporomandibular joint evaluation in mandibular asymmetry. For this study, thirty-two patients who have mandibular asymmetry were selected and submentovertex, panoramic and lateral corrected tomographic radiagraphs were taken. Horizontal and vertical analysis using various landmarks on these radiographs were performed. Also radiographic and clinical evaluation of temporomandibular joint were obtained. Ther results were as follows ; 1. On the submentovertex radiograph, the mean distance of Pogonion to midline was 5.0(+/-)3.8mm. 2. The mean distance of Pogonion to Gonion between the deviated and the contra-lateral side(P<0.001). 3. The distance difference of Pogonion to Gonion between the deviated and the contra-lateral side was significantly realated to the degree of asymmetry(P<0.001). 4. On panoramic radiagraph,the condylar height of the contral-lateral side was significantly longer than the one of the deviated side(P<0.001). 5. On lateral corrected tomogram, bony of temporomandibular joint was observed in 11 condyles of the deviated side and 9 condyles of the contra-lateral side. Erosion and ostephyte were the most common changes in both the deviated and the contra-lateral sides.

PURPOSE: To analyze the possible association between magnetic resonance imaging signal intensity of temporo-mandibular joint disk and posterior attachment, and the type and extent of disk displacement, disk configuration, effusion and clinical signs in patients with internal derangement. MATERIALS AND METHODS: Magnetic resonance images of the 132 temporomandibular joints of 66 patients with temporomandibular joint displacement were analyzed. The clinical findings were obtained by retrospective review of the patients' records. The type and extent of disk displacement, disk configuration and effusion were evaluated on the proton density MR images. The signal intensity from the anterior band, posterior band and posterior attachment were measured on MR images. The associations between the type and extent of disk displacement, disk configuration, effusion and clinical signs and the MR signal intensity of disk and posterior attachment were statistically analyzed by student's t-test. RESULTS: Of 132 joints, 87 (65.9%) showed anterior disk displacement with reduction (ADR) and 45 (34.1%) showed anterior disk displacement without reduction (ADnR). The signals from posterior attachments were lower in joints with ADnR than those of ADR (p<0.05). The results showed statistically significant (p<0.05) association between the type and extent of disk displacement and disk configuration, and decreased signal intensity of posterior attachment. There were no statistical associations between pain, noise and limited mouth opening, and signal intensity of disk and posterior attachment. Conclusions : The average signal from posterior attachment was lower in joints with ADnR than that of ADR. The type and extent of disk displacement and disk configuration appeared to be correlated with the signal intensity from posterior attachment.

Tufted hair follliculitis is a localized, inflammatory and exudative disease of the scalp characterized by a tufted appearance of the scalp hairs emerging from single follicular openings, and may result in permanent and irreversible scarring alopecia. We report two cases of tufted hair folliculitis in a 53-year-old woman and a 47-year-old man. They had several areas of scarring alopecia with multiple bundles of hairs emerging from single follicular orifices. Histopathologic findings were typical for tufted hair folliculitis. The patients were treated successively with oral antibiotics and with topical application of clindamycin.
