Introduction We present the case of a patient with penetrating penile injury caused by splintering floorboards in a gymnasium. Case presentation A 24‐year‐old man was brought to the emergency department of our hospital because of an unintentional penetrating penile injury sustained while playing volleyball at a gymnasium. He dove into the wooden floor to fly‐receive the ball. When sliding with his abdomen on the floor, a wooden splinter from the floorboard stuck from the base of his penis to near the glans penis. The splinter was gently removed without bleeding under local anesthesia. Conclusions Splintering floorboards in gymnasiums can cause serious trauma, including penile injuries. Health‐care workers and users of public facilities, such as gymnasiums, should be aware of the accident risk associated with wooden floors.

Purpose Osteoporosis is a well-known adverse effect of androgen deprivation therapy for prostate cancer. This study aimed to reveal the factors associated with the diagnosis of osteoporosis in prostate cancer patients undergoing androgen deprivation therapy. Methods This retrospective cross-sectional study included 106 prostate cancer patients treated with androgen deprivation therapy. Patients with bone metastasis at the initiation of androgen deprivation therapy and those with castration-resistant prostate cancer were excluded. Bone mineral density was measured at the lumbar spine and femoral neck using dual-energy X-ray absorptiometry. Osteoporosis was defined as bone mineral density equal to or below either −2.5 SD or 70% of the mean in young adults. The association between clinicopathological variables and bone mineral density or diagnosis of osteoporosis was investigated. Results Thirty-six (34%) patients were found to have osteoporosis. The incidence of osteoporosis increased in a stepwise manner depending on the duration of androgen deprivation therapy. Multivariate logistic regression analysis identified a longer duration of androgen deprivation therapy (months, odd’s ratio = 1.017, P = 0.006), lower body mass index (kg/m2, odd’s ratio = 0.801, P = 0.005) and higher serum alkaline phosphatase value (U/l, odd’s ratio 1.007, P = 0.014) as the factors independently associated with the diagnosis of osteoporosis. Eleven out of 50 (22%), 14 out of 35 (40%) and 11 out of 20 patients (55%) were osteoporotic in the patients with serum alkaline phosphatase values <238 U/l, 238–322 U/l and >322 U/l, respectively (P = 0.022). Conclusions Osteoporosis is common in prostate cancer patients undergoing androgen deprivation therapy; furthermore, its incidence increases depending on the duration of androgen deprivation therapy. Bone mineral density testing should be considered for all patients on androgen deprivation therapy, especially for those with a lower body mass index and higher serum alkaline phosphatase value.

Introduction There is a wide range of problems associated with ejaculation, including decreased semen volume, vaginal ejaculation problems, premature ejaculation, delayed ejaculation, hematospermia, and pain associated with ejaculation. However, there is no simple questionnaire that can comprehensively evaluate these ejaculatory functions. Objective In this study, we evaluated the overall ejaculation function of the patients in question using an originally developed ejaculation function score (Kimura and Shoji's Ejaculation Function Score). Methods We examined 20 patients who visited our sexual function outpatient clinic with a chief complaint of ejaculation. As a control group, we also examined 20 patients who had undergone vasectomy using the same score. The questionnaire consisted of the following five items (1) Awareness of sufficient momentum, (2) Pleasant sensation during ejaculation, (3) Presence of pain associated with ejaculation, (4) Presence of blood in semen, and (5) Perception of decreased semen volume. The total score was also evaluated. In addition, satisfaction with the current ejaculation was assessed. Results The mean age of the ejaculation disorder group was 43.5±15.1 years. The main complaints were decreased semen volume in 7 cases (35%), vaginal ejaculation disorder in 6 cases (30%), delayed ejaculation in 2 cases (10%), premature ejaculation in 2 cases (10%), lack of orgasm in 1 case (5%), and pain associated with ejaculation in 1 case (5%). The mean scores for each item were 1.5 for item 1, 1.8 for item 2, 3.0 for item 3, 3.0 for item 4, and 2.0 for item 5, resulting in a mean total score of 11.2. On the other hand, the mean age of the vasectomy group was 42.0±9.4 years, item 1 was 2.8, item 2 was 2.9, item 3 was 3.0, item 4 was 3.0, item 5 was 2.9, and the mean total score was 14.6. When the two groups were compared, significant differences were found except for items 3 and 4. There was also a significant difference in satisfaction of present ejaculation with mean scores of 1.3 and 2.9. As a result of examining the clinical severity and the total score, the total score of 5-6 was considered severe, 7-9 moderate, 10-13 mild ejaculation disorder, and 14-15 within the normal range. Conclusion Although our ejaculation function score is still in the developmental stage, we believe that it can be a screening tool for ejaculation function in practical medical care and self-assessment.
