    Notes: Summary ¶ The authors report a rare case of primary intracranial malignant schwannoma of the trigeminal nerve occuring in a 30-year-old woman without von Recklinghausen's neurofibromatosis (VRNF). The tumour arose from the intracranial part of the left trigeminal nerve, without skull base destruction. The tumour was partially removed operatively, followed by focal 50Gy irradiation, but unfortunately the tumour showed rapid regrowth. A second operation was attempted, but she died of cerebral infarction soon after operation. Histologically, the original tumour was characterized by the presence of foci of extremely high cellularity, pleomorphism and mitosis in an otherwise typical benign schwannoma. Immunohistochemically, the tumour cells were positive for S-100 protein even in the atypical areas, suggesting the tumour to be of Schwann cell origin. However, the recurrent tumour was composed of undifferentiated spindle cells, which were negative for S-100 protein.  Thus, it is possible to consider that the S-100 protein expression could reflect the degree of differentiation of Schwann cells. Furthermore, the postoperative irradiation might have exacerbated the malignant progression in the present case.

    Notes: Abstract An unusual case of the simultaneous occurrence of prostate cancer and IgE myeloma is reported. A 74-year-old man with urinary disturbance and elevated serum prostate-specific antigen level, of 7.4 ng/ml, showed Bence-Jones protein in the urine. Immunoelectrophoresis of the serum showed elevation of IgE kappa monoclonal protein. Radical prostatectomy was performed as a curative therapy for T1c, Gleason 3-2 prostate cancer. The patient has remained free of progression of both the myeloma and the prostate cancer for 26 months after the initial diagnosis.

    Notes: Abstract Cytogenetic, molecular cytogenetic, and molecular studies of prostate cancer have produced a large volume of data about chromosomal loci that are aberrant in prostate cancer. The cumulative data on prostate cancer reveal allelic losses on chromosome arms 2q, 3p, 5q, 6q, 7q, 8p, 9p, 10p, 10q, 11p, 11q, 12p, 13q, 16q, 17p, 17q, 18q, and 21q, but there is a great deal of variability between studies. In most cases, the frequency of allelic loss is higher in metastatic tissues or hormone-refractory tumors than in primary tumors. There also seem to be discrepancies in the genetic findings depending on methods employed. Molecular genetic studies, using polymerase chain reaction (PCR) analysis of microsatellite markers, demonstrated allelic loss at 7q31.1, whereas fluorescence in situ hybridization analysis showed a gain at the same region. Com-mon sites of allelic loss that are consistently observed by various methods seem to exist on chromosome arms 8p, 10q, 13q, and 16q. PTEN/MMAC1 has been identified on 10q23.3 and was found to be frequently mutated in advanced prostate cancer. Other regions are also considered to harbor genes associated with the development and progression of prostate cancer, and these could be included in the diagnostic methods for the substaging of prostate cancer.

    Value of free-to-total prostate-specific antigen ratio for detection and staging of prostate cancer (2000)

    Notes: Abstract Background. We aimed to evaluate the clinical usefulness of measurement of the free-to-total (F/T) ratio of prostate-specific antigen (PSA) for the differentiation of prostate cancer from benign prostate hyperplasia (BPH) and for the staging of prostate cancer. Values for PSA density (PSAD) and PSAD adjusted to the transition zone volume (PSAD-T) were also evaluated in patients with mildly elevated PSA levels (4.1–10 ng/ml). Methods. Total and free PSA and the F/T ratio were determined in 80 men with prostate cancer and 48 men BPH before treatment. PSA levels were measured with a chemiluminescent enzyme immunoassay. Results. Patients with prostate cancer had a significantly lower F/T ratio than those with BPH. A cut-off value of 14% for the F/T ratio provided a positive predictive value of 81.6% and a negative predictive value of 65.4%. The F/T ratio did not differ between patients with clinically localized and metastatic prostate cancer. In patients with a PSA value of 4.1–10 ng/ml, a cut-off value of 14% for the F/T ratio provided a sensitivity of 66.7% and a specificity of 76.2%. Sixty percent of the missed cancer in patients with an F/T value of 14% or more could be rescued using the PSAD value. Conclusion. Measurement of the F/T PSA ratio has good sensitivity and specificity in distinguishing prostate cancer from BPH, especially in patients with a PSA level of 4.1–10 ng/ml. However, compared with serum PSA level, the F/T PSA ratio is not valuable for the clinical staging of prostate cancer.

    Notes: Abstract  Balloon digits were found in two neonates with congenital constriction ring syndrome. The affected digits were the right long finger and right great toe. They were surgically treated at the age of 10 and 9 days, respectively. Morphologic improvement was dramatic after surgery. In cases with extensive enlargement, severe cyanosis, redness, and no subsidence of edema within several days after birth, early operative treatment may be necessary to maintain digit viability and prevent autoamputation due to circulatory embarrassment. It can also be helpful to prevent fibrosis of the subcutaneous tissue. Pathologic examination revealed marked proliferation of fibrous tissue and lymphatic vessels.

    Notes: Abstract  Rationale: Selective drugs are required to test the hypothesis whether antipsychotic effects may be induced or modulated by 5HT2A receptor antagonism. M100907 (previously known as MDL 100,907) is a highly selective 5HT2A antagonist in clinical development. Objective: To test if the suggested clinical dose of 20 mg M100907 daily induces high 5HT2A receptor occupancy in patients with schizophrenia. Methods: The 5HT2A receptor occupancy was determined in two patients with schizophrenia treated with M100907, 20 mg once a day. Positron emission tomography (PET) with 11C-labeled M100907, was performed prestudy and under steady state conditions. Clinical ratings were performed weekly. Results: Clinical treatment with M100907, 20 mg daily induced a very high 5HT2A receptor occupancy in the frontal cortex of both patients (〉90%). M100907 was well tolerated. One patient improved minimally and one patient became minimally worse during treatment. Conclusions: The results confirm that an oral dose of 20 mg per day ensures adequate 5HT2A receptor occupancy for clinical proof of concept. The sample is too small to allow conclusions about the clinical effect.

    Notes: Abstract  Acoustic schwannoma is a slow-growing tumor and usually occurs in adult patients. We report a rare pediatric case of acoustic schwannoma with high proliferative potential. A 10-year-old boy was diagnosed as having a right cerebellopontine angle tumor. The tumor was subtotally resected. Histological examination revealed a typical acoustic schwannoma with a few mitotic figures. Chromosomal analysis showed no abnormality on the long arm of chromosome 22 associated with neurofibromatosis type 2. The lesion regrew rapidly as an acoustic schwannoma, necessitating subtotal resection on three occasions and CyberKnife radiosurgery. The immunohistochemical MIB-1 staining indices of the specimens obtained at the first, second, and third operations were 2.3%, 4.6% and 14.7%, respectively. The immunohistochemical proliferative potential of acoustic schwannoma is discussed.

    Notes: Abstract: We conducted a cross-sectional study of the effects of soybean protein intake on bone mineral density and biochemical markers in 85 postmenopausal Japanese women. Nutrients in the diet of postmenopausal Japanese women visiting the osteoporosis unit, including subjects with normal lumbar spine bone mineral density (L2–4 BMD), were investigated by questionnaire, and the calculated daily energy, protein, soy protein and calcium intake were obtained. L2–4 BMD was measured with dual-energy X-ray absorptiometry, and assays done of serum alkaline phosphatase (ALP) and serum intact osteocalcin (IOC) as bone formation markers and urinary pyridinoline (UPYR) and urinary deoxypyridinoline (UDPYR) as bone resorption markers. Soy protein intake was significantly associated with the Z-score for L2–4 BMD (r= 0.23, p = 0.038) and UDPYR (r =−0.23, p = 0.034). Stepwise multiple regression analyses showed that soy protein intake is significantly associated with the Z-score for L2–4 BMD (β= 0.225, p = 0.04) and UDPYR (β=−0.08, p = 0.03) among four nutritional factors. These results suggest that high soy protein intake is associated with a higher bone mineral density and a lower level of bone resorption, but further studies are needed to confirm the causal dynamic mechanisms.
