ABSTRACT
BACKGROUND: The therapeutic role of pelvic lymph node dissection (PLND) during radical prostatectomy (RP) for prostate cancer is not established. In clinical practice, PLND is primarily performed in cases of high-risk prostate cancer. The detection of lymph node metastasis plays a crucial role in determining the need for subsequent treatments. This study aims to evaluate the prognosis of prostate cancer patients with lymph node involvement (LNI) by stratifying them based on postoperative prostate-specific antigen (PSA) levels to identify biomarkers that can guide postoperative treatment strategies. METHODS: Analysis was conducted on 383 patients, selected from 572 initially eligible, who underwent RP with LNI across 33 Japanese Urological Oncology Group institutions from 2006 to 2019. Patients were grouped according to postoperative PSA levels and salvage treatments received. Follow-up focused on castration resistance-free survival (CRFS), metastasis-free survival (MFS), and overall survival (OS). RESULTS: In the persistent PSA group (PSA ≥ 0.1 ng/mL), CRFS and MFS were significantly shorter compared to the non-persistent PSA group (PSA < 0.1 ng/mL), and there was a tendency for shorter OS. In the persistent PSA group, patients with postoperative PSA values above the median (PSA ≥ 0.52 ng/mL) showed shorter CRFS and MFS. Furthermore, in the PSA ≥ 0.52 group, androgen deprivation therapy (ADT) plus radiotherapy (RT) combination had prolonged CRFS and MFS compared with ADT alone. CONCLUSIONS: This study provides valuable insights into stratifying patients based on postoperative PSA levels to tailor postoperative treatment strategies, potentially improving the prognosis of prostate cancer patients with LNI.
ABSTRACT
OBJECTIVE: The "Summary of Japanese clinical practice guidelines for Bell's palsy (idiopathic facial palsy) - 2023 update edited by the Japan Society of Facial Nerve Research" aims to review the latest evidence regarding the treatment of Bell's palsy and to provide appropriate recommendations. METHOD: Regarding the treatment of Bell's palsy, a guideline panel identified key clinical questions using an analytic PICO framework. The panel produced recommendations following the standards for trustworthy guidelines and the GRADE approach. The panel considered the balance of benefits, harm, and preferences when making recommendations. RESULTS: The panel identified nine key clinical questions: systemic (high/standard dose) corticosteroids, intratympanic corticosteroids, systemic antivirals, decompression surgery, acupuncture, physical therapy, botulinum toxin, and reanimation surgery. CONCLUSION: These guidelines strongly recommend systemic standard-dose corticosteroids for the clinical management of Bell's palsy. Other treatments are weakly recommended due to insufficient evidence. The absolute risk reduction of each treatment differed according to the disease severity. Therefore, physicians and patients should decide on treatment based on the disease severity.
ABSTRACT
BACKGROUND: This study aimed to create a prognostic model to predict disease recurrence among patients with lymph node involvement but no prostate-specific antigen (PSA) persistence and to explore its clinical utility. METHODS: The study analyzed patients with lymph node involvement after pelvic lymph node dissection with radical prostatectomy in whom no PSA persistence was observed between 2006 and 2019 at 33 institutions. Prognostic factors for recurrence-free survival (RFS) were analyzed by the Cox proportional hazards model. RESULTS: Among 231 patients, 127 experienced disease recurrence. The factors prognostic for RFS were PSA level at diagnosis (≥ 20 vs. < 20 ng/mL: hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.09-2.52; P = 0.017), International Society of Urological Pathology grade group at radical prostatectomy (RP) specimen (group ≥ 4 vs. ≤ 3: HR, 1.63; 95% CI 1.12-2.37; P = 0.010), pathologic T-stage (pT3b/4 vs. pT2/3a: HR, 1.70; 95% CI 1.20-2.42; P = 0.0031), and surgical margin status (positive vs. negative: HR, 1.60; 95% CI 1.13-2.28; P = 0.0086). The prognostic model using four parameters were associated with RFS and metastasis-free survival. CONCLUSION: The prognostic model in combination with postoperative PSA value and number of lymph nodes is clinically useful for discussing treatment choice with patients.

OBJECTIVE: This study aimed to reveal the efficacy of physical therapy for patients with peripheral facial palsy. METHODS: A literature search was conducted using PubMed, Ichushi-Web, and Cochrane Central Register of Controlled Trials. Published randomized controlled trials comparing the physical therapy versus placebo/non-treatment for peripheral facial palsy such as Bell's palsy, Ramsay Hunt syndrome, and traumatic facial palsy were included for meta-analysis. The primary outcome was non-recovery at the end of the follow-up. Non-recovery was defined according to the authors' definition. The secondary outcomes were the composite score of the Sunnybrook facial grading system and sequelae (presence of synkinesis or hemifacial spasm) at the end of the follow-up. Data was analyzed using Review Manager software and pooled risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) were calculated. RESULTS: Seven randomized controlled trials met the eligible criteria. The data on non-recovery from four studies was obtained and included 418 participants in the meta-analysis. Physical therapy might reduce non-recovery (RR = 0.51 [95% CI = 0.31-0.83], low quality). Pooling the data of composite score of the Sunnybrook facial grading system from three studies (166 participants) revealed that physical therapy might increase the composite scores (MD = 12.1 [95% CI = 3.11-21.0], low quality). Moreover, we obtained data on sequelae from two articles (179 participants). The evidence was very uncertain about the effect of physical therapy on reduction of sequelae (RR = 0.64 [95% CI = 0.07-5.95], very low quality). CONCLUSION: The evidence suggested that physical therapy reduces non-recovery in patients with peripheral facial palsy and improves the composite score of the Sunnybrook facial grading system, whereas the efficacy of physical therapy in reducing sequelae remained uncertain. The included studies had high risk of bias, imprecision, or inconsistency; therefore, the certainty of evidence was low or very low. Further well-designed randomized controlled trials are needed to confirm its efficacy.

OBJECTIVES: To compare the therapeutic features and oncological outcomes of robot-assisted radical prostatectomy (RARP) with those of open radical prostatectomy (ORP) or laparoscopic radical prostatectomy (LRP) in lymph node (LN) positive prostate cancer patients in a retrospective observational multi-institutional study. PATIENTS AND METHODS: We evaluated the clinical results of 561 patients across 33 institutions who underwent RARP, LRP, or ORP and who were diagnosed with LN-positive prostate cancer during RP with pelvic LN dissection (PLND). We determined the following survival outcomes: metastasis-free survival, overall survival, cancer-specific survival, and biochemical recurrence-free survival. The Kaplan-Meier method, log-rank test, and Cox proportional hazards regression model were used to evaluate the effect of treatment on oncological outcomes. Statistical significance was set at P < 0.05. RESULTS: There was no significant difference for any of the survival outcomes between the three surgical groups. However, RARP achieved a greater LN yield compared to that of ORP or LRP. When the extent of PLND was limited to the obturator LNs, the number of removed LNs (RLNs) was comparable between the three surgical groups. However, higher numbers of RLNs were achieved with RARP compared to the number of RLNs with ORP (P < 0.001) when PLND was extended to the external and/or internal iliac LNs. CONCLUSION: RARP, LRP, and ORP provided equal surgical outcomes for pN1 prostate cancer, and the prognosis was relatively good for all procedures. Increased numbers of RLNs may not necessarily affect the oncological outcome.

The treatment for lymph node involvement (LNI) after radical prostatectomy (RP) has not been established. This study aimed to reveal the outcomes of various management strategies among patients with LNI after RP. Retrospectively, 561 patients with LNI after pelvic lymph node dissection (PLND) with RP treated between 2006 and 2019 at 33 institutions participating in the Japanese Urological Oncology Group were investigated. Metastasis-free survival (MFS) was the primary outcome. Patients were stratified by prostate-specific antigen (PSA) persistence after RP. Cox regression models were used to analyze the relationships between clinicopathological characteristics and survival. Survival analyses were conducted using the Kaplan-Meier method and log-rank test with or without propensity score matching. Prognoses, including MFS and overall survival, were prominently inferior among patients with persistent PSA compared with those without persistent PSA. In multivariate analysis, androgen deprivation therapy (ADT) plus radiotherapy (RT) was associated with better MFS than ADT alone among patients with persistent PSA (hazard ratio = 0.37; 95% confidence interval = 0.15-0.93; p = 0.034). Similarly, MFS and overall survival were significantly better for ADT plus RT than for ADT alone among patients with persistent PSA after propensity score matching. This study indicated that PSA persistence in LNI prostate cancer increased the risk of poor prognoses, and intensive treatment featuring the addition of RT to ADT might improve survival.

We aimed to compare the outcomes of high-dose-rate brachytherapy (HDR-BT) boost and external beam radiation therapy (EBRT) alone for high-risk prostate cancer. This was a single-center, retrospective and observational study. Consecutive patients who underwent initial radical treatment by HDR-BT boost or EBRT alone from June 2009 to May 2016 at the Niigata University Medical and Dental Hospital, Japan were included. A total of 96 patients underwent HDR-BT boost, and 61 underwent EBRT alone. The prescription dose of HDR-BT boost was set to 18 Gy twice a day with EBRT 39 Gy/13 fractions. The dose for EBRT alone was mostly 70 Gy/28 fractions. The high-risk group received >6 months of prior androgen deprivation therapy. Overall survival, biochemical-free survival, local control and distant metastasis-free survival rates at 5 years were analyzed. The incidence of urological and gastrointestinal late adverse events of Grade 2 and above was also summarized. In the National Comprehensive Cancer Network (NCCN) high-risk calssification, HDR-BT boost had a significantly higher biochemical-free survival rate at 5 years (98.9% versus 90.7%, P = 0.04). Urethral strictures were more common in the HDR-BT boost group. We will continuously observe the progress of the study patients and determine the longer term results.

PURPOSE: This study aims to investigate the utility of prostate-specific antigen (PSA) screening by conducting an all-case survey of newly diagnosed prostate cancer patients at Niigata Prefecture, Japan. PATIENTS AND METHODS: Depending on whether patients were subjected to screening, information was prospectively collected on all prostate cancer patients newly diagnosed between October 1, 2019, and September 30, 2020, at all institutions in Niigata Prefecture where urologists performing prostate biopsy routinely work and differences in clinical parameters were investigated. RESULTS: PSA was measured in 478 out of 1332 patients (35.8%) as part of a community health screening. The rate of metastatic carcinoma (M1) in all patients was 14.9%. When patients were divided into three categories of population-based screening (community health screening and workplace health screening), opportunistic screening (PSA measurements at complete medical check-ups or on patient request), and testing triggered by clinical symptoms or findings, the proportion of metastatic cancer was 4.5%, 3.7%, and 30.6%, respectively, demonstrating that the number of distant metastases was significantly lesser in all patients who underwent screening. CONCLUSION: The one-year all-case survey of newly diagnosed prostate cancer patients demonstrated that PSA screening significantly contributed to the early diagnosis of current prostate cancer in Japan.
ABSTRACT
Organic light-emitting diodes (OLEDs) using a liquid organic semiconductor (LOS) are expected to provide extremely flexible displays. Recently, microfluidic OLEDs were developed to integrate and control a LOS in a device combined with microfluidic technology. However, LOS-based OLEDs show poor-colour-purity light emissions owing to their wide full width at half maximum (FWHM). Here we report liquid/solution-based microfluidic quantum dots light-emitting diodes (QLEDs) for high-colour-purity light emission. Microfluidic QLEDs contain liquid materials of LOS for a backlight and QDs solutions as luminophores. The microfluidic QLED exhibits red, green, and blue light emissions and achieves the highest light colour purity ever reported among LOS-based devices for green and red lights with narrow FWHMs of 26.2 nm and 25.0 nm, respectively. Additionally, the effect of the channel depth for the luminophore on the peak wavelength and FWHM is revealed. The developed device extends the capabilities of flexible microfluidic OLEDs-based and QDs-based displays.
ABSTRACT
BACKGROUND: Descending necrotizing mediastinitis is a potentially fatal polymicrobial infection that often leads to dysphagia after treatment. Such dysphagia is likely the result of fibrosis and scarring from inflammatory changes in the fascial space. A case is presented in which the mechanism of dysphagia was verified using two-dimensional analysis of the muscle lengths of the suprahyoid and infrahyoid muscles. CASE: A 57-year-old woman presented with a hyoid and laryngeal movement disorder with pharyngeal residue secondary to descending necrotizing mediastinitis. To treat this disorder, the chin-down maneuver was performed, and it immediately improved hyoid and laryngeal elevation and reduced pharyngeal residue at the epiglottic valleculae and pyriform sinus. Analysis of the mechanism of these improvements revealed that combined head and neck flexion, compared with neck flexion, decreased the distance between the origin and insertion (DOI) of the sternohyoid muscle (SM) and increased the muscle contraction rate and the maximum contraction duration of the geniohyoid muscle (GM) during swallowing. DISCUSSION: In the present case, the patient had restrictions in extension of the SM that applied resistance to GM contraction. Compensation of this condition was achieved by combined head and neck flexion, which decreased the DOI of the SM, thereby improving the contractile function of the GM.
ABSTRACT
OBJECTIVE: To estimate the outcomes of high-dose-rate brachytherapy combined with hypofractionated external beam radiotherapy in prostate cancer patients classified as very high risk by the National Comprehensive Cancer Network. METHODS: Between June 2009 and September 2015, 66 patients meeting the criteria for very high-risk disease received high-dose-rate brachytherapy (2 fractions of 9 Gy) as a boost of external beam radiotherapy (13 fractions of 3 Gy). Androgen deprivation therapy was administered for approximately 3 years. Biochemical failure was assessed using the Phoenix definition. RESULTS: The median follow-up period was 53 months from the completion of radiotherapy. The 5-year biochemical failure-free, distant metastasis-free, prostate cancer-specific and overall survival rates were 88.7, 89.2, 98.5 and 97.0%, respectively. The independent contribution of each component of the very high-risk criteria was assessed in multivariable models. Primary Gleason pattern 5 was associated with increased risks of biochemical failure (P = 0.017) and distant metastasis (P = 0.049), whereas clinical stage ≥T3b or >4 biopsy cores with Gleason score 8-10 had no significant impact on the two outcomes. Grade 3 genitourinary toxicities were observed in two (3.0%) patients, whereas no grade ≥3 gastrointestinal toxicities occurred. CONCLUSIONS: The present study shows that this multimodal approach provides potentially excellent cancer control and acceptable associated morbidity for very high-risk disease. Patients with primary Gleason pattern 5 are at a higher risk of poor outcomes, indicating the need for more aggressive approaches in these cases.

BACKGROUND: Steep Trendelenburg position (ST) during robot-assisted radical prostatectomy (RARP) poses a risk of increase in intraocular pressure (IOP) in men receiving robot-assisted radical prostatectomy (RARP). The aim of the study was to identify clinicopathological factors associated with increased IOP during RARP. METHODS: We prospectively studied 59 consecutive prostate cancer patients without glaucoma. IOP was measured at 6 predefined time points before, during and after the operation (T1 to T6). RESULTS: Compared with T1, IOP decreased after beginning of anesthesia(T2) (by - 6.5 mmHg, p < 0.05), and increased 1 h after induction of pneumoperitoneum in the steep Trendelenburg position (ST) (T3) (+ 7.3 mmHg, p < 0.05). IOP continued to increase until the end of ST (T4) (+ 10.2 mmHg, p < 0.05), and declined when the patient was returned to supine position under general anesthesia (T5) (T1: 20.0 and T5: 20.1 mmHg, p above 0.05). The console time affected the elevation of IOP in ST; IOP elevation during ST was more prominent in men with a console time of ≥4 h (n = 39) than in those with a console time of < 4 h (n = 19) (19.8 ± 6.3 and 15.4 ± 5.8 mmHg, respectively, p < 0.05). Of the 59 patients, 29 had a high baseline IOP (20.0 mmHg or higher), and their IOP elevated during ST was also reduced at T5 (T1: 22.6 and T5: 21.7 mmHg, p above 0.05). There were no postoperative ocular complications. CONCLUSIONS: Console time of < 4 h is important to prevent extreme elevation of IOP during RARP. Without long console time, RARP may be safely performed in those with relatively high baseline IOP.

We describe the kinetics of excimer electrogenerated chemiluminescence (ECL) of a liquid pyrene derivative, 1-pyrenebutyricacid 2-ethylhexylester (PLQ) dissolved in a molecular solvent, acetonitrile (MeCN), and an ionic liquid, triethylpentylphosphonium bis(trifluoromethanesulfonyl)imide ([P2225][TFSI]). Pyrene was also used for comparison. To discuss the kinetics of the excimer ECLs, the photophysical and electrochemical properties and electronic states of PLQ and pyrene were revealed. The photoluminescence (PL) spectra, rate constants for the radiative transitions, and redox potentials of PLQ and pyrene dissolved in MeCN and [P2225][TFSI] suggest that as a solvent, [P2225][TFSI] behaves more polar than MeCN. By analyzing the PL decay curves, the rate constants to form the excimer were determined to be on the order of 109 and 107 M-1 s-1 in MeCN and [P2225][TFSI], respectively, which were limited by the diffusion. For neat PLQ (1.6 M), a delay of 0.3-0.4 ns for the excimer emission compared to the monomer emission was observed. It is likely that the delay corresponds to the timescale for arranging the conformation to form the excimer. The ECL of PLQ was generated by applying a square wave voltage to produce the radical anion and cation, and on the ECL spectra, the excimer emission was more prevailed compared to the PL spectra. Kinetic analysis for the electron transfer reaction between the radical ions based on Marcus theory indicates that the electron transfer is limited by the diffusion of the radical ions. Moreover, the electron transfer distance (det) between the radical cation and anion to generate excited states was calculated with a framework of the theory. Kinetically, the electron transfer can take place at det < â¼11 Å in MeCN and det < â¼12 Å in [P2225][TFSI]. The density functional theory (DFT) and time-dependent DFT calculations show that the potential energy curve of the excimer against the distance between the pyrene rings reaches a minimum at 3.50 Å. This suggests that through the electron transfer, the process of the direct formation of the monomer S1 state followed by the excimer formation is more prevailed than that of the direct excimer formation.
ABSTRACT
We herein report an unusual case of brain metastasis from prostate cancer during androgen deprivation therapy and post-docetaxel and definitive local therapy. The brain metastasis was surgically resected followed by Whole-brain radiation therapy. Postoperatively, his PSA again decreased to an undetectable level and remained undetectable with no evidence of new or recurrent disease.
ABSTRACT
OBJECTIVE: Post-stroke hemiplegic patients with a spastic clenched fist deformity that was caused by upper motor neuron syndrome often have problems with hygiene and nursing. Botulinum toxin-A (BTX-A) had been given for treatment of such patients to relieve spasticity by targeting finger joint muscles, such as the flexor digitorum superficialis and flexor digitorum profundus. However, some of these patients do not have satisfactory outcomes. Therefore, we aimed to examine the clinical efficacy and outcome of BTX-A treatment that targeted the upper lumbrical muscles (ULM) in patients with spastic clenched fist deformity caused by stoke. METHODS: Chronic stroke patients with spastic clenched fist deformity who received BTX-A treatment were evaluated retrospectively. We obtained data from medical records before and at 4 weeks after BTX-A injection to the ULM. The clinical data and outcome measures analyzed included range of motion, the Modified Ashworth Scale, the numeric graphic rating scale for pain, and 2 items from the disability assessment scale (ease of cleaning palm and trimming nail). RESULTS: Wilcoxon signed rank test showed that BTX-A treatment significantly improved all measures. CONCLUSION: BTX-A therapy to the ULM provided satisfactory outcomes in improving spastic clenched fist.

ABSTRACT Purpose: The purposes of the present study were to evaluate growth rate of nonfunctioning adrenal incidentalomas (AIs) and their development to hormonal hypersecretion on follow-up. Materials and methods: A retrospective study was conducted from the electronic medical records. A total of 314 patients were diagnosed with adrenal tumors between 2000 and 2016. After excluding patients who had overt adrenal endocrine disorders or whose adrenal tumors were clinically diagnosed as metastatic malignancies, we investigated 108 patients with nonfunctioning AIs including characteristics, the treatment, the way of follow-up and pathology. Results: Fifteen patients received immediate adrenalectomy because of the initial tumor size or patient's preference. Pathological examination revealed malignancy in 2 patients. In the remaining 93 patients, radiological examinations were performed periodically. Tumor enlargement of ≥ 1.0cm was observed in 8.6% of the patients who were followed up as nonfunctioning AIs with a median follow-up period of 61.5 months (range: 4-192). Eleven patients underwent adrenalectomy. On the pathological examinations, all of the tumors, which showed a size increase, were diagnosed as benign tumors. Regarding the followed up patients without adrenalectomy, only 2.4% of the patients had tumor enlargement during the prolonged follow-up. Furthermore, none of the patients developed hormonal hypersecretion or clinical signs such as obesity, glucose intolerance or poorly controlled hypertension. Conclusions: Tumor enlargement of AIs did not correlate with malignancy. The value of repeat radiological and hormonal examinations may be limited in the long-term follow-up of patients whose AIs are not enlarged.

INTRODUCTION: Adverse events with enzalutamide widely used for men with castration-resistant prostate cancer are of interest. CASE PRESENTATION: A 76-year-old man developed castration-resistant prostate cancer. He received 160 mg of enzalutamide daily. On the 13th day after treatment, severe thrombocytopenia was observed (platelet count: 1.9 × 104/µL). Normal coagulation and fibrinolytic systems suggested thrombocytopenia induced by enzalutamide. Enzalutamide was withdrawn immediately, and platelet count uneventfully recovered to 7.0 × 104/µL and 28.8 × 104/µL 9 and 30 days after discontinuation, respectively. He restarted enzalutamide therapy without thrombocytopenia recurrence. However, 81 days after restarting enzalutamide, he experienced a seizure. There were no significant findings from brain computed tomography, which suggested that the seizure was also an enzalutamide-associated adverse event. CONCLUSION: Thrombocytopenia may occur early following enzalutamide therapy, and blood analysis within 2 weeks after treatment may facilitate its management. Enzalutamide-induced thrombocytopenia, complicated by seizure, has not been reported.
ABSTRACT
BACKGROUND: Mirror feedback rehabilitation is effective in preventing the development of oro-ocular synkinesis following severe facial palsy. However, we do not have effective maneuvers to prevent the deterioration of oculo-oral synkinesis. We developed a new method of biofeedback rehabilitation using tape for the prevention of oculo-oral synkinesis. OBJECTIVE: The aim of the present study was to investigate the efficacy of taping feedback rehabilitation. METHODS: Twelve consecutive patients with peripheral facial nerve palsy who developed synkinesis were divided into 2 groups. Six patients were treated with the new training method, and the remaining 6 patients were treated with conventional therapy as controls. In the experiment group, tape was placed around the mouth, and the patient was instructed to close the eyes so that no movements of the mouth would be perceived from sensations of the taped skin. After 4 weeks of training, facial movements were recorded and movie images were graded for mouth synkinesis using the revised Sunnybrook facial grading system by examiners blinded to patient grouping. RESULTS: Mouth corner contraction during eye closure was significantly weaker in the experimental group than in the control group. CONCLUSIONS: Our new feedback method could help prevent the deterioration of oculo-oral synkinesis.

OBJECTIVE: To verify the feasibility and effectiveness of a newly developed modified jaw opening exercise (MJOE) in post-stroke patients with pharyngeal residue who completed a sixweek exercise regimen. DESIGN: Double-blind, randomized, controlled trial. PARTICIPANTS: 16 patients with stroke-related dysphagia. INTERVENTIONS: Participants were allocated to an intervention group (MJOE: one set of five repetitions at 80% maximum voluntary contraction (MVC) for 6 seconds) or a control group (isometric jaw closing exercise: one set of five repetitions at 20% MVC for 6 seconds). Each group performed four sets a day, five times a week, for a total of six weeks. MAIN OUTCOME MEASURES: A videofluorographic swallowing study was performed before and after exercise. The distance between the mental spine and the hyoid bone (DMH) and hyoid displacement (HD) were measured. RESULTS: Twelve participants completed the study. No pain in the temporomandibular joint and/or anterior region of the neck occurred during the exercise period. In the intervention group (N=6), a decrease in DMH where anterior HD ended and an increase in anterior HD were seen. In the control group (N=6), no changes were seen. CONCLUSIONS: MJOE is feasible without any adverse events in poststroke patients, and it promotes anterior HD during swallowing.
