ABSTRACT
OBJECTIVE: Demand for erectile dysfunction treatments has increased not only in elderly patients but also in young patients. Reports indicate that frequent causes of erectile dysfunction in Japan are organic disorders in elderly patients and psychogenetic disorders in young patients. METHODS: We defined patients under the age of 40 as young erectile dysfunction patients, and those over 65 as elderly erectile dysfunction patients. We divided these two groups and conducted a retrospective comparative study based on medical questionnaires. We selected 215 cases of patients under the age of 40, and 176 cases of patients over the age of 65, and created a group of young patients and a group of elderly patients. We implemented the erectile hardness score, Sexual Health Inventory for Men, and sexual encounter profile questions 2 and 3 as the patient's daily clinical journal. RESULTS: The median age of young patients was 36 years, and that of elderly patients was 70 years. With respect to Sexual Health Inventory for Men, the average score was a significantly higher score in the young patients (9.26 vs 7.10, P < 0.001). Concerning erectile hardness score, young patients showed significantly higher scores in erectile hardness score (3.15 vs 2.06, P < 0.001). In terms of sexual encounter profile question 2, 50.9% of young patients responded "yes," but 24.3% of elderly patients responded, thus indicating a significantly higher score in young patients. In terms of sexual encounter profile question 3, 6.1% of young patients responded "yes," and 0.7% of elderly patients responded "yes," indicating a significantly higher in young patients. CONCLUSIONS: The results showed that many young patients with erectile dysfunction were able to perform insertion, but were unable to maintain erection.

OBJECTIVES: To investigate the correlation between the Erection Hardness Score and both erectile function and metabolic and lifestyle factors. METHODS: This study included 548 men who underwent a complete standard medical checkup at Yokohama Shin-midori General Hospital between 1 July 2016 and 31 August 2018, and answered the question about erectile hardness. The following variables were evaluated: age, erectile hardness on the Erection Hardness Score, erectile function on the Sexual Health Inventory for Men, current medical history (diabetes, hypertension, dyslipidemia, heart disease, stroke), metabolic risk factors (abdominal circumference, hyperglycemia, high blood pressure, lipid abnormality) and lifestyle factors. First, to examine the correlation between erectile hardness and erectile function, the mean Sexual Health Inventory for Men score by Erection Hardness Score grade was determined for each age group. Then, an analysis was carried out to examine the association between erectile hardness and age, current medical history, metabolic risk factors, and lifestyle factors. RESULTS: In each age group, a lower Erection Hardness Score grade was associated with a lower mean Sexual Health Inventory for Men score. Lipid abnormality, diabetes and age were independent risk factors for decreased erectile hardness. CONCLUSIONS: Erection Hardness Score is a useful tool that can easily and accurately assess erectile function in the settings of medical checkups and clinical practice. Diabetes and lipid abnormality affect erectile hardness.

(Objective) Enzalutamide is an oral androgen-receptor inhibitor that prolongs survival in men with castration-resistant prostate cancer (CRPC). We retrospectively evaluated clinical efficacy and safety of enzalutamide in CRPC. (Patients and methods) We reviewed clinical records of 73 patients who had received enzalutamide for the CRPC at Showa University and affiliated 7 hospitals. Enzalutamide was given at a dose of 160 mg/day, but some patients were treated at lower dose because of there age or poor performance status. Prostrate-specific antigen (PSA) response, prior docetaxel use and the previously administered agents were evaluated retrospectively. (Results) The median patients age was 77 years, the median Gleason score was 9 and the median PSA level at baseline was 26.9 ng/ml. The patients who had prior docetaxel use were 29 (39.7%) and the median of total docetaxel dose was 460 mg/body. The median number of total prior treatments (anti-androgens, Estramustine and steroid) was 3. Twenty seven (61.4%) patients with docetaxel-naïve achieved over 50% reduction of PSA level from baseline, but only 7 (24.1%) in patients previously treated with docetaxel. The most common adverse events included fatigue (24.7%), anorexia (24.7%) and the nausea (16.4%). We found a small proportion of responders to enzalutamide experienced a PSA flare. (Conclusion) Our results of the use of Enzaltamide for CRPC were similar with previous reports. PSA flare was found in some patients with CRPC who responded to enzaltamide. It should be noted that this possible PSA flare phenomenon.
