We reviewed the knee radiographs of 68 cases of arthroscopically-proven discoid lateral meniscus to evaluate usefulness of plain radiographs in diagnosing discoid lateral meniscus. The subject included 42 cases of complete type and 26 cases of incomplete type discoid lateral meniscus. Knee radiographs of 70 cases which had no pathology of the meniscus in knee arthroscopy were used as controls. We excluded patients who had a significant history of trauma and who were under 16 years of age or over 60 to avoid measuring radiographs of skeletally immature or degenerative knees. The absolute values and relative normalized values of specific knee dimensions such as a squared-off appearance of the lateral femoral condyle, widened femorotibial joint space, cupping of the lateral tibial plateau, obliquity of the lateral tibial plateau articular surface, high fibular head and hypoplasia of the Iateral intercondylar spine in discoid lateral meniscus and normal controls were compared. Among these dimensions, high fibular head and widened lateral tibiofemoral joint space showed statistically significant difference between the discoid lateral meniscus group and normal control group. We suggest that these findings could be useful in screening lateral discoid meniscus in plain radiographs.

Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

OBJECTIVE: The aim of this study was to identify human papilloma virus(HPV) infection in cervical lesions by using polymerase chain reaction in situ hybridization(PCR-ISH) and to compare the results of PCR-ISH with conventional in situ hybridization(ISH) METHODS: Forty-seven randomly chosen neutral-buffered formalhyde-fixed cervical biopsies in which cervical intraepithelial neoplasia and invasive cervical cancer had been diagnosed were tested for HPV DNA by PCR-ISH and ISH. The method of PCR-ISH includes deparaffinization of specimens, PCR amplification of DNA, in situ hybridization and detection of amplified products. RESULTS: The positivity rate of ISH was 36% for all biopsies and 26%, 40% for CIN and invasive cancer respectively. By using PCR-ISH the positivity was 80%, 84% respectively. All PCR-ISH positive cases were ISH positive and no ISH positive was PCR-ISH negative. CONCLUSION: In our study HPV DNA, undetectable by standard in situ hybridization, was detectable by PCR in situ hybridization. Our study shows that PCR in situ hybridization is highly sensitive method for detection of HPV in cervical neoplastic specimens with morphological evidence.

Background : It has been suggested that thrombospondin (TSP) is a p53-dependent negative regulator of tumor angiogenesis. TSP expression and localization in hepatocellular carcinomas (HCCs) and its association with overexpression of p53 protein were investigated. Methods : TSP-1 and -2 expressions were examined in 40 HCC specimens by immunohistochemical staining and in 4 HCC cell lines by Western blotting. In addition, p53 protein expression and microvessel density (MVD) were correlated with the TSP expression. Results : Strong immu- nopositivity for TSP-1 was observed in fibroblasts, vascular endothelial cells, and some vas- cular smooth muscle cells of the stroma in 18 cases (45%), and in tumor cells in 3 cases (7.5%) of 40 cases of HCC. Immunoreactivity for TSP-2 was observed in only the sinusoidal lining cells of the tumor in 15 cases (46%), and in tumor cells in 2 cases (6%) of 32 cases of HCC. TSP-1 expression was inversely correlated with MVD (p=0.028), but TSP-2 expression did not show any correlation with MVD. Although p53 was overexpressed in 17 cases, there was no significant correlation between TSP and p53 expressions. None of the HCC cell lines expressed TSP-1 or -2. Conclusions : These findings indicate that TSP-1 is mainly derived from nonparenchymal cells, and may decrease tumor angiogenesis in HCC.

A 24-year-old pregnant woman started to have severe hyperemesis gravidarum at 6 weeks' gestation. Six weeks later, dizziness, ataxia, visual disturbance, diplopia and confusion were developed. On admission, she presented ophthalmoplegia, nystagmus, deaeased tendon reflex, intention tremor, ataxia, confusion and memory disturbance. She was diagnosed to Wernicke-Korsakoff syndrome and 100mg of thiamine was administered intravenously daily till 28 weeks gestation and then intramuscularly. Her ocular symptns, together with neurological signs, were gradually improved. Memory disturbance slightly improved but remained at the time of delivery. The case will be presented in more details with a brief revie of literatures.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.
