There has been a recent increase in mumps orchitis among pubertal and postpubertal males. These outbreaks can be attributed to a reduction in the uptake of measles-mumps-rubella (MMR) vaccine during the early to mid-1990 s in children who have now matured. The mumps virus is commonly associated with extra-salivary complications. Unvaccinated postpubertal males diagnosed with mumps virus frequently develop complications such as mumps orchitis. Therefore, it is important that urologists are familiar with the diagnosis, treatment and complications of this condition. Here we review the epidemiology, clinical presentation, diagnostic methods, treatment options and complications of mumps orchitis, as a complication of mumps virus, with particular emphasis on testicular atrophy, subfertility and infertility.

    • "The bilateral presentation and histopathology are compatible with late changes in severe mumps orchitis. This condition is not associated with testicular tumors (Davis et al., 2010). Zhang et al. (2013) suggest that the benign teratomas and dermoid cysts of the post-pubertal testis could in fact be late appearing pediatric teratomas. "

    ABSTRACT: Four cases are reported meeting the criteria of a pediatric (i.e., Type I) testicular germ cell tumor (TGCT), apart from the age of presentation, which is beyond childhood. The tumors encompass the full spectrum of histologies of pediatric TGCT: teratoma, yolk sac tumor, and various combinations of the two, and lack intratubular germ cell neoplasia/carcinoma in situ in the adjacent parenchyma. The neoplasms are (near)diploid, and lack gain of 12p, typical for seminomas and non-seminomas of the testis of adolescents and adults (i.e., Type II). It is proposed that these neoplasms are therefore late appearing pediatric (Type I) TGCT. The present report broadens the concept of earlier reported benign teratomas of the post-pubertal testis to the full spectrum of pediatric TGCT. The possible wide age range of pediatric TGCT, demonstrated in this study, lends credence to the concept that TGCT should according to their pathogenesis be classified into the previously proposed types. This classification is clinically relevant, because Type I mature teratomas are benign tumors, which are candidates for testis conserving surgery, as opposed to Type II mature teratomas, which have to be treated as Type II (malignant) non-seminomas.

    • "Although there have been several reports examining the resurgence in mumps, there have been few studies of the characteristics of postpubertal mumps and mumps orchitis in patients after MMR vaccination [7]. Park et al. [8] reported on an outbreak of mumps in vaccinated males, but they did not include a description of mumps orchitis. "

    ABSTRACT: Although the measles-mumps-rubella vaccination covers most children against mumps in Korea, the development of mumps has been reported. However, the clinical manifestations of mumps orchitis in postpubertal vaccinated patients have never been investigated. Herein we report the clinical features of mumps orchitis in postpubertal vaccinated patients. This study included a total of 62 postpubertal males who developed acute mumps orchitis from 2005 to 2010. The clinical manifestations such as the incubation period, febrile duration, and the mean duration of orchitis were retrospectively investigated. The laboratory and sonographic findings were also reviewed and compared with the features of previously reported cases of unvaccinated postpubertal mumps orchitis. The mean age of the 62 patients was 17.56 years (range, 15 to 29 years). All patients were serologically confirmed with acute mumps infection (positive immunoglobulin [Ig] M and negative or positive IgG). The mean incubation period was 5.39 days (range, 0 to 23 days), with a febrile duration of 1.8 days (range, 0.5 to 3 days), and a mean duration of orchitis of 4.96 days (range, 0 to 17 days). Sonography revealed unilateral orchitis in 58 patients (93.6%) and bilateral orchitis in only 6 (6.4%). In our study, mumps orchitis in postpubertal vaccinated patients showed a relatively shorter febrile duration. In addition, less scrotal swelling and a lower incidence of bilaterality were found upon physical examination and ultrasonography. In the future, additional long-term follow-up is needed to determine the features of mumps orchitis in postpubertal vaccinated males, and an additional booster vaccination should be considered.

    ABSTRACT: Measles, rubella, mumps and chicken pox are highly contagious viral infectious diseases that may cause potentially serious complications, in particular in immunocompromised patients, newborns and pregnant women. In Italy, vaccine coverage remains sub-optimal and outbreaks continue to occur with heavy impact on public health. Immunization is one of the most beneficial available public health measures to prevent serious illness, severe complications, disabling sequelae and deaths. Attenuated live virus vaccines have been commercially available since the '90s and their efficacy, safety and favourable cost-benefit ratio have been extensively documented.
