Miller-Dieter syndrome consists of severe type I lissencephaly, abnormal facial appearance, and sometimes other birth defects. Lissencephaly is a brain malformation manifested by a smooth cerebral surface, thickened cortical mantle, and microscopic evidence of incomplete neuronal migration. It comprises the agyria-pachygyria spectrum of malformation, thus excluding polymicrogyria and other cortical dysplasia. Type I lissencephaly results from abnormal migration between about 10 and 14 weeks gestaion. The brain is often small, and the ventricle is enlarged posteriorly The corpus callosum may be small or absent. The structural pattern of the cerebral hemispheres and ventricles is distintly immature, reminiscent of fetal brain. The superficial cellular layer resembles an immature cortex, with some separation into zones similar to layers III, V, and VI of normal cortex, although the cell population is decreased. In 1963 Miller described a malformation syndrome in a brother and sister with postnatal growth deficiency, craniofacial defects, and serious abnormalities of neurologic function. Autopsy at 3 and 4month of age, respectively, revealed lissencephaly. Subsequently, Dieker reported four additional patients with this disorder and referred to it as the 'lissencephaly syndrome'. We have experienced a case with this syndrome. Then we report this rare case with brief review of literature.

The purpose of this study is to evaluate the diagnostic accuracy of various quantitative indices for the differentiation of benign from malignant primary soft tissue tumors by FDG-PET. A series of 32 patients with a variety of histologically or clinically confirmed benign (20) or malignant (12) soft tissue lesions were evaluated with emission whole body (5min/bed position) PET after injection of [18F]FDG. Regional 20min transmission scan for the attenuation correction and calculation of SUV was performed in 16 patients (10 benign, 6malignant) followed by dynamic acquisition for 56min. Postinjection transmission scan for the attenuation correction and calculation of SUV was executed in the other 16 patients (10 benign, 6 malignant). The following indices were obtained : the peak and average SUV (pSUV, aSUV) of lesions, tumor-to-background ratio acquired at images of 51 min p.i. (TBR51), tumor-to-background ratio of areas under time-activity curves (TBRarea) and the ratio between the activities of tumor ROI at 51 min p.i. and at the time which background ROI reaches maximum activity on the time-activity curves (T51/Tmax). The pSUV, aSUV, TBR51, and TBRarea, in malignant lesions were significantly higher than those in benign lesions. We set the cut-off values of pSUV, aSUV, TBR51, TBRarea and T51/Tmax for the differentiation of benign and malignant lesions at 3.5, 2.8, 5.1, 4.3 and 1.55, respectively. The sensitivity, specificity and accuracy were 91.7%, 80.0%, 84.4% by pSUV and aSUV, 83.3%, 85.0%, 84.4% by TBR51, 83.3%, 100%, 93.8% by TBRarea and 66.7%, 70.0%, 68.8% by Tsl/Tmax. The time-activity curves did not give additional information compared to SUV or TBR. The one false negative was a case with low-grade fibrosarcoma and all four false positives were cases with inflammatory change on histology. The visual analysis of FDG-PET also detected the metastatic lesions in malignant cases with comparable accuracy. In conclusion, all pSUV, aSUV, TBR51, and TBRarea are useful metabolic semi-quantitative indices with good accuracy for the differentiation of benign from malignant soft-tissue lesions.

PURPOSE: Although the pudendal nerve terminal motor latency (PNTML) is normally used, there is no definite test that accurately reflects the function of the pudendal nerve. This study was undertaken to determine the relative accuracy of the various methods in measuring the function of the pudendal nerve. METHODS: Thirty one female patients (age 51.3+/-15.7) with a defecation disorder (constipation 20, fecal incontinence 11) were evaluated prospectively using a neurophysiologic test and balloon reflex manometry. Five parameters such as the right and left PNTML, anal mucosal electrosensitivity, latency and the amplitude of the rectoanal contractile reflex (RACR) were analyzed statistically for their correlation. RESULTS: There was no significant inter-test correlation among the parameters. However, the intra-test correlations between the parameters such as the right and left PNTML (r=0.9629, P<0.001)/latency and the RACR amplitude (r= -0.3770, P=0.0366) were found to be significant. CONCLUSION: The accuracy of these tests in evaluating the pudendal neuropathy could not be determined. However, because it can be assumed that a measurement of the RACR in addition to RNTML is technically accurate, it there will need to be more study for it to be used as an alternative to a PNTML measurement.

Malignant melanoma of the urinary bladder is very rare, 7 cases were reported in the literature. The tumor shows early metastasis with poor prognosis. Treatment measures include surgical extirpation, radiotherapy and chemotherapy but the results were bad.Herein, we report a case of malignant melanoma of the urinary bladder in a 45-year-old man which was managed by transurethral resection and combination chemotherapy.

The purpose of this present study was to investigate the effect of autogenous bone with histological evaluation of regenerated bone after sinus elevation. The study involved genaral healthy 6 patients participated in this study and were treated with 2-stage sinus elevation procedures using a combination of demineralized freezeddried bone allograft (DFDBA) and coralline calcium carbonate with or without autogenous bone. At 6months after sinus elevation, bone specimens were obtained and stained with Hematoxylin-Eosin for light microscopic evaluation. The results of this study were as follows : 1. Autogenous bone grafts present trabecular patterns at 6 months in test groups, consist of woven bone and lamellar bone, but more compact than control groups. 2. Resorption of bone graft particles, osteoblast-like cells, newly formed osteoid tissue were observed at 6 months in test groups, but seems to be more frequently than control groups. 3. New osteoid tissue was formed from the surface of graft materials and gradually expanded around them. 4. The appearance of connective tissue around graft materials was densely formed, but more prominent in test groups than control groups. 5. Bone graft particles were resorbed incompletely and slight inflammatory infiltrate, newly formed capillaries, and adipocytes were observed. From the above results, autogenous bone is effective in bone regeneration after sinus elevation, could provide favorable conditions in implant placement.
