Outcome of acute epididymo-orchitis: risk factors for testicular loss.

PURPOSE: Acute epididymo-orchitis (AEO) is a common urological condition characterised by pain and swelling of the epididymis which can affect men of any age. The aetiology and to some extent the management of the patient differ between paediatric and young and older adult groups. METHODS: A retrospective analysis was performed at the University Hospital Limerick from 2012 to 2016. Hospital In-Patient Enquiry (HIPE) data were obtained for all patients diagnosed with orchitis, epididymitis, epididymo-orchitis or testicular abscess over this 5-year period. RESULTS: 140 patients were identified, the age range was 0-89, median age 35.6. These were then split into 3 clinical groups, pre-pubertal (Group 1, 0-15-year-olds), sexually active young men (Group 2a, 16-35-year-olds) and men over 35 (Group 2b). Nine patients had an abscess on ultrasound investigation. There was a significant correlation between the presence of an abscess and the need for an orchidectomy (2 patients, P = 0.035). Two patients were reported as having an atrophic testis following AEO and both were in Group 2b. CONCLUSION: Overall, 7/131 (5%) patients had loss or atrophy of a testicle following an episode of AEO. Nineteen patients had further readmissions with AEO (14%).

COVID-19 vaccination is associated with a decreased risk of orchitis and/or epididymitis in men.

Vaccine hesitancy is a major public health obstacle to fighting the ongoing COVID-19 epidemic. Due to studies that show COVID-19 infection can affect sperm parameters and lead to orchitis, the public are concerned about the effect of the COVID vaccines on male reproduction. In this study, we investigated the association between COVID-19 vaccination and risk of developing orchitis and/or epididymitis outcomes in a cohort of men using a large, US-based, electronic health record database. After balancing for confounding variables, we found that receiving at least 1 COVID-19 vaccine is associated with a decreased risk of developing orchitis and/or epididymitis.

Ultrasound Imaging Findings of Acute Testicular Infection in Patients With Coronavirus Disease 2019: A Single-Center-Based Study in Wuhan, China.

OBJECTIVES: Coronavirus disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic, raising widespread public health concerns. Our team treated hospitalized patients with COVID-19 in Wuhan, where the outbreak first began, and we suspected that SARS-CoV-2 may cause testicular infection in male patients. We conducted this study to explore that observation. METHODS: We enrolled male patients with a confirmed diagnosis of COVID-19 and performed a bedside ultrasound (US) examination of the scrotum, focused on findings of acute inflammation such as tunica albuginea thickening, enlargement and heterogeneous echogenicity of the testis, epididymis, or both, an abscess, scrotal wall edema, and hydrocele. Then we compared the proportions of observed epididymo-orchitis in patients from different age groups and COVID-19 severity groups. RESULTS: A total of 142 patients with COVID-19 were enrolled in our study, and 32 (22.5%) patients had acute orchitis, epididymitis, or epididymo-orchitis on scrotal US imaging, according to the diagnosis criteria. The observed risk of acute scrotal infection increased with age, with the incidence reaching 53.3% in men older than 80 years. We also observed that men with severe COVID-19 had a significantly higher possibility of epididymo-orchitis compared to the nonsevere COVID-19 group (P = .037). CONCLUSIONS: This study shows US imaging evidence that SARS-CoV-2 may cause infection of the testis or epididymis, and the risk is worthy of the attention of clinicians.

Comparison between microsurgical varicocelectomy with and without testicular delivery for treatment of varicocele: A systematic review and meta-analysis.

The present study was conducted to assess the semen parameters, complications and clinical effect of microsurgical varicocelectomy with testicular delivery (TD) for treatment of varicocele. Relevant studies were collected and reviewed systemically from PubMed, Medline, Embase, Web of Science, China National Knowledge Infrastructure databases and the Cochrane Library and a meta-analysis was performed. Relative ratio (RR), standardised mean difference (SMD) and their 95% confidence intervals (CIs) were adopted to estimate the outcome measures. Eight articles and a total of 1,139 subjects including 487 patients with TD in microsurgical varicocelectomy and 652 patients without TD were enrolled in this meta-analysis. The pooled RR indicated that microsurgical varicocelectomy with TD increased the incidence of orchiepididymitis (RR = 4.36, 95% CI = 1.12-16.99, p = 0.034) and scrotal oedema (RR = 4.25, 95% CI = 2.40-7.54, p = 0.000) than microsurgical varicocelectomy without TD postoperatively. In conclusion, compared to microsurgical varicocelectomy without TD, TD to further ligate the gubernacular veins in microsurgical varicocelectomy results in a higher incidence of orchiepididymitis and scrotal oedema and take longer operation time. However, TD may not have any beneficial influences on semen parameters, serum testosterone, varicocele occurrence, wound infection and natural conception.

Large outbreak of mumps virus genotype G among vaccinated students in Norway, 2015 to 2016.

From 6 September 2015-May 2016, a large mumps outbreak occurred among vaccinated students in Norway. A case was defined as a person presenting with a clinical mumps infection, notified between 1 September 2015 and 30 June 2016. Confirmed cases had positive laboratory confirmation and probable cases had an epidemiological link; PCR-positive specimens were genotyped. A total of 232 cases were notified (230 confirmed) with median age of 23 years (range 4-81) and 61% were male. Of 68 (30%) confirmed cases that were genotyped, 66 were genotype G and associated with the outbreak. Cases that had received two doses of the measles-mumps-rubella (MMR) vaccine had reduced risk of hospitalisation (adjusted relative risk (aRR): 0.14; 95%CI: 0.03-0.57), mumps-related orchitis (aRR: 0.21; 95% CI: 0.08-0.55) and severe outcome (aRR: 0.25; 95% CI: 0.10-0.62) compared with those unvaccinated. A third dose of the vaccine was offered to approximately 1,300 fully vaccinated close contacts and subsequently reported cases decreased. This large outbreak, occurring among predominately vaccinated students, suggests the current genotype A vaccine offers suboptimal protection against mumps genotype G. We recommend maintaining high vaccination coverage and offering the vaccine to all unvaccinated individuals.

Prostatitis, other genitourinary infections and prostate cancer: results from a population-based case-control study.

PURPOSE: We relied on a population-based case-control study (PROtEuS) to examine a potential association between the presence of histologically confirmed prostate cancer (PCa) and history of genitourinary infections, e.g., prostatitis, urethritis, orchitis and epididymitis. PATIENTS AND METHODS: Cases were 1933 men with incident PCa, diagnosed across Montreal hospitals between 2005 and 2009. Population controls were 1994 men from the same residential area and age distribution. In-person interviews collected information about socio-demographic characteristics, lifestyle and medical history, e.g., self-reported history of several genitourinary infections, as well as on PCa screening. Logistic regression analyses tested overall and grade-specific associations, including subgroup analyses with frequent PSA testing. RESULTS: After multivariable adjustment, prostatitis was associated with an increased risk of any PCa (OR 1.81 [1.44-2.27]), but not urethritis (OR 1.05 [0.84-1.30]), orchitis (OR 1.28 [0.92-1.78]) or epididymitis (OR 0.98 [0.57-1.68]). The association between prostatitis and PCa was more pronounced for low-grade PCa (Gleason ≤ 6: OR 2.11 [1.61-2.77]; Gleason ≥ 7: OR 1.59 [1.22-2.07]). Adjusting for frequency of physician visits, PSA testing frequency or restricting analyses to frequently screened subjects did not affect these results. CONCLUSION: Prostatitis was associated with an increased probability for detecting PCa even after adjustment for frequency of PSA testing and physician visits, but not urethritis, orchitis or epididymitis. These considerations may be helpful in clinical risk stratification of individuals in whom the risk of PCa is pertinent.

Protective effect of vaccination against mumps complications, Czech Republic, 2007-2012.

BACKGROUND: In the Czech Republic, two-dose immunization against mumps achieves 98% coverage. The routine reporting detects mumps cases, clinical complications, and hospital admissions in unvaccinated but also in vaccinated individuals. Using surveillance data of patients with mumps we assessed the effectiveness of mumps vaccination on mumps clinical complications and hospitalization need. We also investigated the effect of the time since immunization. METHODS: We analysed data on incident mumps cases reported to the Czech national surveillance system in 2007-2012. Using a logistic regression model with adjustment for age, sex, year of onset, and the administrative region, the association between vaccination and the most frequent mumps complications and hospitalization was evaluated. The adjusted odds ratios (ORa) for mumps complications were compared between the vaccinated and non-vaccinated groups, reflecting the vaccine effectiveness (VEa) computed as VEa = (1-ORa) × 100. We estimated the risk of mumps complications by the time from vaccination. RESULTS: From total of 9663 mumps analysed cases 5600 (58%) occurred in males. The mean age at the disease onset was 17.3, median 16 years. Ninety percent of the study patients had no complications, while 1.6% developed meningitis, 0.2% encephalitis, and 0.6% pancreatitis. Mumps orchitis occurred in 659 (11.8%) male cases. In total, 1192 (12.3%) patients required hospitalization. Two doses of vaccine received by 81.8% cases significantly reduced the risk of hospitalization: ORa 0.29 (95% CI: 0.24, 0.35). Two doses showed statistically significant VEa 64% (95% CI: 46, 79) for meningitis, 93% (95% CI: 66, 98) for encephalitis in all cases, and 72% (95% CI: 64, 78) for orchitis in males. Vaccine effectiveness for orchitis declined from 81 to 74% and 56% in the most affected age groups 10-14, 15-19, and 20-24 years, respectively. Among 7850 two-dose recipients, the rate of complications rose from below 1 to 16% in categories up to 6 years and 24 and more years after the second dose, respectively. CONCLUSIONS: This study demonstrates a significant preventive effect of two-dose vaccination against mumps complications (orchitis, meningitis, or encephalitis) and hospitalization for mumps. The risk of complications increases with time interval from vaccination. Teenagers and young adults were the most affected age groups.

Estimating true hospital morbidity of complications associated with mumps outbreak, England, 2004/05.

Mumps outbreaks in highly vaccinated populations continue to be reported globally. Therefore, quantifying the burden of mumps morbidity accurately will be necessary to better assess the impact of mumps vaccination programmes. We aim to estimate the true morbidity resulting from mumps complications in terms of hospitalised orchitis, meningitis, oophoritis and pancreatitis in England during the outbreak in 2004/05. This outbreak in England led to a clear increase in hospitalisations coded to mumps for complications of orchitis in those born in the 1970s and 1980s and possibly for meningitis in those born in the 1980s. A simple statistical model, based on analysing time trends for diagnosed complications in hospital databases with routine laboratory surveillance data, found that the actual morbidity was much higher. There were 2.5 times (166 cases) more mumps orchitis cases in the 1970s cohort and 2.0 times (708 cases) more mumps orchitis cases in the 1980s cohort than complications coded to mumps in hospital databases. Our study demonstrated that the mumps outbreak in England 2004/05 resulted in a substantial increase in hospitalised mumps complications, and the model we used can improve the ascertainment of morbidity from a mumps outbreak.

ASSOCIATION OF MEAN PLATELET VOLUME AND THE MONOCYTE/LYMPHOCYTE RATIO WITH BRUCELLA-CAUSED EPIDIDYMO-ORCHITIS.

We evaluated the association between the mean platelet volume (MPV) and monocyte/lymphocyte ratio (MLR) with brucella-caused epididymo-orchitis to determine if they could be used to differentiate between brucella and non-brucella epididymo-orchitis. The charts of 88 patients with non-brucella and 14 patients with brucella epididymo-orchitis were retrospectively reviewed. Brucellosis was diagnosed by isolating Brucella spp from a blood culture or from a serum agglutination titer ≥ 1:160 along with accompanying clinical findings. The patients with brucella epididymo-orchitis were significantly more likely to have a lower MPV and a higher MLR than those with non-brucella epididymo-orchitis. Using a MPV cut-off level of less than 9.25 fl to differentiate brucella from non-brucella epididymo-orchitis gives a sensitivity of 78.6%, a specifity of 78.4%, a positive predictive value of 36.7% and a negative predictive value of 95.8%. Using a MLR cut-off level of greater than 0.265 to differentiate brucella from non-brucella epididymo-orchitis gives a sensitivity of 71.4%, a specifity of 65.9%, a positive predictive value of 25% and a negative predictive value of 93.5.%. MPV and MLR values may assist in differentiating between brucella and non-brucella epididymo-orchitis.

[EPIDIDYMO-ORCHITIS IN PREPUBERTAL CHILDREN--PREVALENCE, ETIOLOGY, SUGGESTED DIAGNOSIS ALGORITHM].

Gonadal inflammation (GI) is a common disease that may affect prepubertal boys. Neonates may suffer from bacterial infection due to congenital or aging processes affecting the urinary tract. This inflammatory process is also prevalent in prepubertal boys. However, in this group, the etiology, the needed imaging modalities and proper management have not yet been clearly defined. This manuscript will systematically review the various etiologies causing GI in pre-pubertal boys, discuss the proper imaging needed, and image interpretation and will provide treatment and follow-up recommendations.

Transvesical prostatectomy in the management of benign prostatic hyperplasia in a developing country.

CONTEXT: The surgical management of benign prostatic hyperplasia (BPH) is evolving away from open surgery. In developing countries however majority of cases are managed by transvesical prostatectomy (TP). AIMS: This study aims to describe our experience regarding the efficacy, complication profile and outcome of TP in the management of BPH in Nigeria. SETTINGS AND DESIGN: A descriptive, retrospective study carried out in three tertiary centers. SUBJECTS AND METHODS: Two hundred and ninety-seven patients were studied. Parameters examined included age, clinical features, investigations, type of postoperative bladder irrigation, prostate gland volume, duration of hospital stay, complications and outcome. STATISTICAL ANALYSIS USED: Simple means and percentages with SPSS 16. RESULTS: Mean age was 65.2 ± 6.8 years (range 47-93 years). Presentation with severe lower urinary tract symptoms only occurred in 76 patients (25.7%); acute urinary retention was seen in 106 patients (35.7%). Chronic urinary retention, impaired renal function and haematuria occurred in 47 (15.8%), 37 (12.5%), and 31 patients (10.4%) respectively. On comorbidity, 63 patients (21.2%) were hypertensive and 24 patients (8.1%) had diabetes mellitus. Two hundred and twenty three patients (75%) had indwelling catheters at the time of surgery. Preoperative urinary catheter duration was 1 week-35 months. Mean duration of hospital stay was 8.8 days. Complications were transient urinary incontinence 33 patients (11.1%), urinary tract infection 38 patients (12.7%), and acute epididymoorchitis 15 patients (5.1%). Clot retention occurred in 40 patients (13.5%). Mortality rate was 1%. CONCLUSIONS: TP remains useful in developing climes. There is a need to emphasize effective preoperative workup so as to limit morbidity. Emphasis on variety of techniques for hemostasis is necessary.

Mumps epidemiology in Germany 2007-11.

In Germany, mumps has been notifiable until 2013 only in the five Eastern federal states (EFS) of former East Germany. Due to different immunisation policies until 1990 and varying vaccination coverages thereafter, mumps incidences cannot be extrapolated to the 11 Western federal states (WFS). We studied mumps-related International Classification of Diseases (ICD-10) code diagnoses claimed through statutory health insurances between 2007 and 2011 to estimate countrywide mumps incidences in the outpatient sector, and compared them with case numbers from ambulatory notification data. Overall, 32,330 outpatient mumps cases were claimed. Annual incidence ranged between 9.3/100,000 and 11.8/100,000 and showed a significant decreasing trend. Compared with EFS, mumps incidence in WFS was higher and indicated a shift towards older age groups. Notified outpatient case numbers in EFS were 13-fold lower and from voluntary surveillance during an outbreak in the WFS Bavaria 8-fold lower than from insurance data (n=316 versus n=4,217 and n=238 versus 1,995, respectively). Of all notified cases with available information, 75.4% (EFS) and 57.6% (Bavaria) were unvaccinated; 6.8% (EFS) and 19.3% (Bavaria) required hospitalisation. In Germany, mumps is still endemic despite decades of vaccination, with considerable underreporting in the established notification systems.

Epidemiology of mumps, mumps complications, and mumps orchitis in Korea using the National Health Insurance Service database.

PURPOSE: To analyze the presentation of mumps and mumps orchitis using the National Health Insurance Service Database (NHISD). MATERIALS AND METHODS: Using information from the NHISD representing all cases of mumps in Korea, data regarding mumps orchitis were analyzed. The International Classification of Diseases, Tenth Revision, and Clinical Modification codes were used for diagnosis. The incidence estimates of the number of mumps cases were analyzed using the Statistical Analysis System (SAS) software. RESULTS: Based on the NHISD, 199,186 people were diagnosed with mumps, and males accounted for 62.3% cases. Teen males accounted for 69,870 cases, the largest number of patients diagnosed with mumps. The annual incidence of mumps increased every year (poisson regression, hazard ratio [HR] 1.026, 95% confidence interval [CI] 1.024-1.027; p<0.025). The risk of mumps was lower in females than that in males (poisson regression, HR 0.594, 95% CI 0.589-0.599; p<0.001). Of the 199,186 patients diagnosed with mumps, 3,872 patients (1.9%) had related complications. Among the mumps complications, the most diagnosed complication was mumps orchitis, which was seen in 41.8% of the males. Mumps orchitis cases accounted for less than 1.5% of the patients with mumps in minors under the age of 20 years and was somewhat higher in 2009 and 2013-2015. CONCLUSIONS: Among the complications related to mumps, meningitis was most common in females, while orchitis was dominant in males. Mumps orchitis also shows periodic outbreaks but is particularly prevalent in adults, which suggests the potential need for additional vaccination against mumps.

Testicular involvement of Brucellosis: A 10-year, multicentre study.

INTRODUCTION: The genito-urinary system is one of the most common areas of involvement in brucellosis. To present the epidemiological, clinical, and laboratory characteristics of patients with testicular involvement associated with brucellosis, together with the diagnostic and therapeutic approaches. METHODOLOGY: Patients followed up for brucellosis-related testicular involvement between January 2012 and November 2022 were included in the study. Brucellosis is defined as the production of Brucella spp. in cultures, or clinical symptoms together with the serum standard tube agglutination test titer of ≥ 1/160. Inflammation in scrotal Doppler ultrasonography was based on testicular involvement. RESULTS: A retrospective evaluation was made of the data of 194 patients with brucellosis-related testicular involvement. The rate of determination of testicular involvement in brucellosis was 2.57%. The most affected patients were determined in the 16-30 years age range. On presentation, brucellosis was in the acute stage in 83.7% of patients. The most common symptoms on presentation were swelling and/or pain in the testes (86.6%). In the patients where a spermiogram could be performed, oligospermia was determined in 41.7%, and aspermia in 8.3%. When the testicular involvement of brucellosis was evaluated, epididymo-orchitis was present at the rate of 55.7%, epididymitis at 27.3%, and testis abscess at 5.1%. CONCLUSIONS: Although epididymo-orchitis was the most frequently determined form of involvement in this study, there was also seen to be a significant number of patients presenting with epididymitis. Male patients presented with the clinical status of brucellosis should be questioned about swelling and pain in the testes to avoid overlooking testicular involvement.

Childhood infections, orchitis and testicular germ cell tumours: a report from the STEED study and a meta-analysis of existing data.

BACKGROUND: Similarities between the age-specific incidence pattern of testicular germ cell tumours (TGCTs) and the age-specific incidence pattern of cancers of viral origin prompted us to evaluate the relationship between common infections occurring during childhood or young adult life and TGCT using existing data from the US Servicemen's Testicular Tumor Environmental and Endocrine Determinants (STEED) case-control study. METHODS: TGCT cases diagnosed between 2002 and 2005 (n=767) were matched on age, race and serum draw date to at least one control (n=929). RESULTS: None of the infections evaluated were associated with TGCT risk. Further, a meta-analysis of mumps and mumps orchitis or orchitis infection did not support an association with TGCT (mumps pooled odds ratio (OR): 1.03, 95% confidence interval (CI): 0.89-1.20; mumps orchitis or orchitis pooled OR: 1.80, 95% CI: 0.74-4.42). CONCLUSION: Based on our evaluation of childhood and early life infections and meta-analyses of mumps and mumps orchitis and/or orchitis, TGCT does not appear to be associated with common childhood infections.

Frequency of epididymo-orchitis in hospitalized patients with acute scrotum at Shohadaye Ashayer Hospital, Khorramabad, Iran.

OBJECTIVE: To investigate the frequency of epididymo-orchitis in patients with acute scrotum. METHODS: In this five-year cross sectional study from March 2004 to June 2009, 83 patients who were hospitalized for acute scrotal pain at Shohadaye Ashayer Hospital in Khorramabad were investigated. First, urine analysis and urine culture tests were carried out followed by sonography if necessary. In cases of suspicious sexual activities, serologic tests and urethral secretion culture were also carried out. In patients whose response to treatment was unsatisfactory after 48 hours, brucellosis and tuberculosis were investigated. RESULTS: Out of 83 patients with epididymo-orchitis, there were positive urine cultures in 69 patients. In 52 (62.7%) of these patients, 30 were infected with E. Coli, 9 with Klebsiella, 8 with Pseudomonas, and 5 cases with Proteus, respectively. In 17 cases, tuberculosis and ischaemic orchitis were observed. CONCLUSION: Among common causes of epididymo-orchitis, rare causes such as tumour, tuberculosis, and brucellosis must be taken into consideration. In all these cases sufficient time for the follow-up should be taken into account.

Spermiogram part of population with the manifest orchitis during an ongoing epidemic of mumps.

INTRODUCTION: Incidence mumps infection has declined since the introduction of the inevitable MRP vaccination during the stage of childhood. In Bosnia and Herzegovina (BIH), from a period of February 2011 until today, there is an evident inclination of the recorded cases of the mumps infection. Orchitis usually occurs in between 3 to 10 days after the parotitis and is found with the post-puberty population. AIM: The aim of the study is to confirm the changes that occur during an early stage of the spermiogram and hormonal status, and after treated mumps orchitis, the patients treated in the Clinic for the Infectious Diseases. PATIENTS AND METHODS: Retrospectively, the analysis of 54 historical diseases was undertaken. During the research stage, the patients after being discharged have made an inquiry to our clinical consultancy units with final results of the spermiogram and hormone-FSH, LH and testosteron. The data analysis was processed with the SPSS program for Windows. RESULTS: the average length of the hospitalization period was in between 8 (medium) days, and average age M (mean) = 21,9 +/- 5,4 years. The speriogram of the treated patients was undertaken one month after the acute phase of the disease and has shown the following results: azoospermia with 14 patients (25,9%), oligospermia with 30 patients (55,6%) and normospermia with 10 patients (18,5%). During the hormonal status with 11 patients (20,4%), the results have shown the inclination of the value in FSH hormons, with 11 patients (20,4%), have shown the lesser value of the testosterons. CONCLUSION: The current study suggests that post-orhitis atrofia is expected within a period of 2-3 months after the infection, and thus, the monitoring on the patients' treatment would continue. The male infertility as a result of mumps ocrhitis is controversial and continues to be the thematic issue as well as the effect of orchitis on testicular endocrine function. Key words: epidemic, mumps

Impact of vaccine effectiveness and coverage on preventing large mumps outbreaks on college campuses: Implications for vaccination strategy.

Recent mumps outbreaks among highly vaccinated populations, including college students, have called into question the vaccine effectiveness (VE) of routine two-dose measles, mumps, and rubella (MMR2) immunization. We aimed to estimate the VE required for a novel vaccination strategy (e.g., MMR booster dose, novel vaccine) to prevent large mumps outbreaks on college campuses. Using mumps college outbreak data reported to the U.S. Centers for Disease Control and Prevention during 2016-2017, we estimated current MMR2 VE using the screening method and implemented a compartmental model of mumps transmission. We performed 2000 outbreak simulations, following introduction of an infectious person to a population of 10,000, over ranges of MMR2 vaccine coverage (VC) and VE (30.0-99.0%). We compared the impact of varying VC and VE on mumps and mumps orchitis case counts and determined VE thresholds that ensured < 5.0% and < 2.0% of the outbreak simulations exceeded 20 and 100 mumps cases. Median estimated MMR2 VE in reported mumps outbreaks was 60.5% and median reported MMR2 VC was 97.5%. Simulated mumps case count was more sensitive to changes in VE than in VC. The opposite was true for simulated mumps orchitis case count, though orchitis case count was small (mean <10 cases across simulations for VE near 60.5% and VC near 97.5%). At 97.5% VC, 73.1% and 78.2% VE were required for < 5.0% and < 2.0% of outbreaks, respectively, to exceed 100 mumps cases. Maintaining 97.5% VC, 82.4% and 85.9% VE were required for < 5.0% and < 2.0% of outbreaks, respectively, to exceed 20 cases. We conclude that maintaining current levels of MMR2 VC, a novel vaccination strategy aimed at reducing mumps transmission must achieve at least 73.1-85.9% VE among young adults to prevent large mumps outbreaks on college campuses.

The increasing incidence of mumps orchitis: a comprehensive review.

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.

Comparision of Brucella and Non-Brucella Epididymo-orchitis.

OBJECTIVE:  To find parameters for differential diagnosis between Brucella epididymo-orchitis (BEO) and non-brucella epididymo-orchitis (NBEO) cases with comparison of BEO and NBEO in terms of inflammatory markers, full urinalysis (FU) for pyuria, and abscess formation (AF). STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Agri State Hospital Urology and Infectious Disease Clinics, between January 2014 and  November 2017. METHODOLOGY: Data of the patients, who were diagnosed with epididymo-orchitis, were divided in BEO and NBEO groups on the basic of serum agglutination test. Parameters including age, white blood cell neutrophil, lymphocyte, monocyte, platelet, mean platelet volume, C-reactive protein (CRP), neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, platelet / lymphocyte ratio, and FU. The values were statistically compared. RESULTS: One hundred and thirty-eight (138) patients were found eligible for the study. Twenty-three (23) of these patients (16.66%) had BEO, and 115 (83.33%) had NBEO. BEO vs. NBEO cases were significantly different regarding mean age (26.17 ±8.15 vs. 48.53 ±21.78 years, p=0.0001) and frequency of pyuria (3,13.04%) vs. 89 (77.39%, p=0.001). However CRP values i.e. 6.07 ±6.59 vs. 6.07 ±5.85 mg/dl (p=0.999) was not significantly different. CONCLUSION: BEO cases are often younger and do not have pyuria or abscess formation. High frequency of pyuria was found in NBEO cases. CRP levels cannot be used in the differential diagnosis between BEO and NBEO cases. Key Words: Abscess formation, Brucella epididymo-orchitis, C-reactive protein, Orchiectomy, Pyuria.
