Significance of PSA Screening in Niigata, Japan: Survey of Actual Status of New Cases of Prostate Cancer.

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.

Conservative management of bilateral traumatic testicular dislocation in a 10-year-old boy.

A 10-year-old boy fell from a one-meter-high Jacuzzi ladder in a hot spring facility, landing in a straddle position, and injured his perineum. He visited the emergency room of our hospital immediately after the injury. Magnetic resonance imaging (MRI) revealed a tear of the corpus spongiosum urethra, and compression due to a hematoma. With the hematoma spreading to the scrotum, the testes became inverted and dislocated to the inguinal region on both sides. Without surgery or interventions, the testes descended into the scrotum on the third day after the injury before fibrillation and scarring began. Testicular dislocation by injury is rare and encountered exclusively in children. It is generally treated with surgery to retain testicular function. We selected conservative management, as our patient had a closed injury without testicular torsion, and the testicular dislocation was associated with compression by hematoma, which could possibly recover with regression of the hematoma.

Ventricular Rhythm and Hypotension in a Patient with Pheochromocytoma-induced Myocardial Damage and Reverse Takotsubo Cardiomyopathy.

A 33-year-old woman experienced near-syncope at a hospital. Electrocardiography revealed an intermittent ventricular rhythm. The echocardiogram at admission indicated mild hypokinesis and severe diffuse hypokinesis with reverse takotsubo cardiomyopathy on the following day. The patient experienced abdominal pain on the admission day, and computed tomography identified a large left adrenal mass. Her catecholamine levels increased remarkably on the third day. The wall motion improved on the twelfth day. The tumor was successfully resected and the patient was diagnosed with an ectopic pheochromocytoma. The ventricular rhythm with myocardial damage and hypotension induced by the reverse takotsubo cardiomyopathy masked the characteristic symptoms of pheochromocytoma.

Influence of hot flashes on quality of life in patients with prostate cancer treated with androgen deprivation therapy.

BACKGROUND: We surveyed patients with prostate cancer treated with androgen deprivation therapy to examine the influence of hot flashes on quality of life (QOL). METHODS: Fifty-five outpatients with prostate cancer (M0, 39; M1, 16) treated with androgen deprivation therapy (castration, 15; castration and antiandrogen, 40) were enrolled in this study. Mean duration of androgen deprivation therapy was 21 months (2-91 months). The patients were still being treated with androgen deprivation therapy at the time of the survey. The functional assessment of cancer therapy (FACT) was used as a QOL questionnaire for outpatients with prostate cancer treated with androgen deprivation therapy. Hot flash assessments were used to document the number and severity (mild, moderate, and severe) of daily hot flashes. The patients prescribed fluvoxamine maleate were reassessed for hot flashes 2 weeks after the prescription. RESULTS: Thirty-two of the 55 patients (58.2%) suffered from hot flashes. Hot flashes deteriorated the physical well-being subscale of QOL in patients with prostate cancer treated with androgen deprivation therapy (P = 0.043). There was a significant relationship between the desire to be treated for hot flashes and the hot flash assessments (P = 0.038). Fluvoxamine maleate was significantly effective in reducing hot flashes (P = 0.001). CONCLUSIONS: Hot flashes had adverse effects on the patients' physical status and deteriorated the patients' QOL. New treatment options such as fluvoxamine maleate might help simplify the often difficult management of hot flashes in patients with prostate cancer treated with androgen deprivation therapy.

Renography as a measure of renal and neobladder function in patients with ileal bladder substitution.

INTRODUCTION: Using renography, we evaluated the function of both the kidneys and neobladder of 20 patients who underwent ileal bladder substitution. METHODS: The patients were measured for renal and neobladder function with renography using 99mTc MAG3. Renal function was assayed in every renal unit using O'Reilly patterns. Voiding function was estimated using radioisotope counts for the reservoir. RESULTS: Thirty-two of 37 renal units had normal renograms. Five renal units showed non-obstructive renograms. The percentage of total residual urine (RU) in the reservoir was 30% and more in 6 patients, 10-30% in 8, and <10% in 6. In 7 of 12 patients, the data on estimated RU correlated with the data on measured RU. However, in 5 patients, the data on estimated RU increased more in quantity than the data on RU measured at another time. CONCLUSIONS: In patients with bladder substitution the functions of both the kidneys and neobladder could be evaluated in a single renography.
