Late testicular relapse two decades after primary extragonadal germ cell tumor with uncommon metastases: a case report.

Background: Extragonadal germ cell tumor (EGCT) is a relatively rare condition, reportedly representing 3-7% of all germ cell tumors. We report a patient who had metachronous testicular tumor with uncommon metastases 20 years after primary retroperitoneal EGCT treatment, along with a corresponding literature review.

Case Presentation: A 49-year-old Japanese man visited our department in November 2017 with chief complaints of indolent right scrotum enlargement and a right inguinal mass.

Influence of Genetic Polymorphisms and Concomitant Anxiolytic Doses on Antidepressant Maintenance Doses in Japanese Patients with Depression.

To prevent recurrent depression, patients should ideally continue treatment for >6 months with the antidepressant dose that effectively suppressed acute depressive symptoms. However, there are inter-individual differences in the antidepressant doses required to achieve response and maintenance. Therefore, this study was conducted to examine the role of clinical features, including genetic polymorphisms, on the antidepressant dose required for maintenance therapy in 82 Japanese patients with depression.

Genotype distributions and allele frequencies of possible major depressive disorder-associated single nucleotide polymorphisms, cyclic adenosine monophosphate response element binding protein 1 rs4675690 and Piccolo rs2522833, in a Japanese population.

It is known that the onset of major depressive disorder (MDD) would be associated with genetic factors. To investigate the susceptibility to psychiatric disorders, e.g.
