    Notes: The coherent anti-Stokes Raman scattering (CARS) and coherent Stokes Raman scattering (CSRS) line shapes near the 1350 cm−1 region of acridine in the T1 state were recorded in the various resonance (ω1 frequency) conditions over the Tn←T1 absorption band in the n-heptane solution at room temperature. The ω1 frequency dependencies of CARS and CSRS line shapes of the T1 signal at 1368 cm−1 were simulated well on the basis of the theoretical χ(3) expression. On the other hand, the ω1 frequency dependence of the line shape of the extra resonance (ER) signal observed at 1335 cm−1 in CSRS, showing no obvious change of the line shape by changing the ω1 frequencies, could not be simulated at all on the basis of the similar expression. The discrepancy of the ER line-shape simulation was discussed.

    Notes: During the course of diamond growth by dc plasma chemical vapor deposition, characteristics of the plasma have been measured by means of the Langmuir single probe method and emission spectrometry. For the source gas system of hydrogen and methane (gas ratio: CH4/H2=2/100, total gas pressure: 2.66×104 Pa), it is revealed that the statistical temperatures of hydrogen atoms and electrons in the positive column of the plasma are obtained to be 4.8×103–5.3×103 K and 1×105–1.1×105 K, respectively. The amount of ionized species is fairly small. By calculating the equilibrium constant of gas molecules in these gas temperature ranges, it is found that molecules over 99% H2 and CH4 are decomposed to the neutral H and C atoms.

    Notes: Abstract The patient was a 47-year-old male, who visited Hidaka Hospital with a chief complaint of swelling in the right inguinal region and the scrotum. With a diagnosis of a right spermatic cord tumor, right high orchiectomy was performed. Since an inflammatory type of malignant fibrous histiocytoma (MFH) was diagnosed from histopathological findings, chemotherapy and radiation therapy were performed as postoperative treatment. Malignant fibrous histiocytoma with the primary focus of the spermatic cords is a rare disease. To our knowledge, this is the 20th case of MFH of the spermatic cord in Japan (the 42nd in the world) and it is the second case of inflammatory type of MFH in Japan.

    Notes: Abstract Background: It is important to establish a procedure with which to confirm the preservation of the cavernous nerves during nerve-sparing radical surgery. For this purpose, we examined changes in intracavernous pressure (ICP) following electrical stimulation of the neurovascular bundle (NVB) with respect to the continuity of the cavernous nerves.Methods: Six cases of radical prostatectomy and eight cases of radical cystoprostatectomy were examined. In all cases, prior to prostate removal, electrical stimulation of the site where the NVB was determined to run was performed and the changes in ICP measured. In eight cases, ICP changes were also measured following prostate removal.Results: Prior to prostate removal, ICP changes could be measured in all 28 sides of 14 cases. These changes were classified into two patterns: stimulation-related increases of convex waveform (t1) were observed in 24 sides (85.7%); and waveforms with reversed type (t2), which was thought to be an incomplete type t1, were observed in four sides (14.3%). There were no ICP changes following non-sparing or incomplete sparing of NVB macroanatomically. Of five sides where the NVB was supposedly completely preserved macroanatomically, ICP changes consisted of type t1 on three sides, t2 on one side and type t2 or no change on a single side. All measurements were obtained within 10 min. Neither electrical stimulation nor measurement of ICP caused any adverse effects.Conclusion: Intraoperative stimulation of the NVB while monitoring ICP changes provides a simple and reliable method of accurately evaluating the preservation of the cavernous nerves.

    Notes: Abstract A case of sarcomatoid transitional cell carcinoma of the renal pelvis is reported. It was distinguished from carcinosarcoma by immunohistochemical study. The tumor was difficult to distinguish from a renal parenchymal tumor in imaging studies because it originated from a duplicated renal pelvis.

    Notes: The goal of this study was to evaluate the correlation between increments of penile tumescence and penile rigidity measured by the erectometer and the RigiScan, respectively.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:Nocturnal penile tumescence (NPT) was measured in 25 volunteers (mean age, 49.5 years). The erectometer and the RigiScan were used simultaneously for a total of 47 nights. We studied the correlation between maximum penile circumferential changes determined by the erectometer and penile rigidity patterns measured by the RigiScan.〈section xml:id="abs1-4"〉〈title type="main"〉Results:Maximum circumferential changes during NPT measured by the erectometer were well correlated to those determined by the RigiScan (correlation coefficient, 0.719). In addition, penile circumferential changes measured by the erectometer corresponded well to the penile rigidity pattern determined by the RigiScan (P = 0.0001). Specifically, maximum penile circumferential changes of more than 30 mm and less than 10 mm had 70% positive predictive value and 100% negative predictive value for predicting the normal rigidity pattern, respectively.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Penile circumferential changes measured by the erectometer were well correlated to penile rigidity measured by the RigiScan, particularly when the increments were larger than 30 mm or less than 10 mm. These results suggested that the erectometer was a useful tool to estimate the penile rigidity patterns of the RigiScan.

    Notes: Background: It is important to preserve the neurovascular bundle (NVB) during nerve-sparing surgery. This article presents the preliminary results of our monitoring system for the postoperative preservation of erectile function.Methods: In 15 patients undergoing radical prostatectomy and 20 patients undergoing radical cystoprostatectomy, intraoperative electrical stimulation along the NVB was performed to measure changes in intracavernous pressure before and after prostate removal. Seven of the radical prostatectomy patients and eight of the radical cystoprostatectomy patients underwent nerve-sparing surgery. Postoperative erectile function was evaluated in 25 patients not receiving adjuvant hormonal therapy.Results: The NVB was judged to be preserved at least on one side electrophysiologically in 14 of 15 patients. Pathologically, three patients had pT3 cancer. Postoperatively, sufficient erectile function was demonstrated using the International Index of Erectile Function 5 in three patients, nocturnal penile tumescence in three patients, and a questionnaire or an interview in three patients. The other patients were incompletely erectile. None of the 11 patients not receiving adjuvant hormonal therapy, in whom NVB was not preserved, were erectile.Conclusion: If the successful criterion of nerve-sparing surgery is defined as a change in intracavernous pressure of 4 cm H2O or more being observed at least unilaterally, and the successful criteria of erectile function preservation includes being sufficiently erectile as revealed by an interview, the sensitivity of our system was 69.2% (9/13) and the specificity was 100% (12/12). Neither adverse reactions to the measurement, nor inadequacy of cancer excision accompanying NVB sparing, were observed. These results suggest that our system can predict postoperative erectile function fairly accurately.

    Notes: Aim: Vitamin D acts as an antiproliferative agent against prostate cells. Epidemiological study has shown that a low level of serum vitamin D concentration is a risk factor for prostate cancer. Vitamin D acts via vitamin D receptor (VDR), and an association of genetic polymorphisms of the VDR gene has been reported. In the current study, we examined the association of VDR gene polymorphisms with familial prostate cancer in a Japanese population.Methods: We performed a case–control study consisting of 81 familial prostate cancer cases and 105 normal control subjects. Three genetic polymorphisms (BsmI, ApaI and TaqI) in the VDR gene were examined by the restriction fragment restriction length polymorphism method.Results: Overall, there was no significant association of the VDR gene polymorphisms with familial prostate cancer risk in the cases and control subjects. However, a weak association between BsmI or TaqI genotypes and cancer risk was observed in subjects under 70 years of age. Stratification of cases by clinical stage or pathological grade did not show significant association between the VDR gene polymorphisms and prostate cancer risk.Conclusion: In the present study, we could not confirm any significant association between VDR gene polymorphisms with familial prostate cancer risk in a Japanese population. Further large-scale case–control studies are warranted to confirm the importance of VDR gene polymorphisms in familial prostate cancer.

    Notes: Abstract We present here a hook that can be used to free both hands from holding the endoscope during endourological procedures. We made the hook from a wire hanger, and thus, it is a convenient, cheap and easy tool to make using this everyday item. As this hook makes the insertion of the endoscope into the urethra easier, it allows urologists to perform endourological procedures, which require the handling of biopsy forceps, a basket wire and lithotripsy probes, unassisted.
