Sex Cord-Gonadal Stromal Tumor of the Rete Testis

A 34-year-old tetraplegic patient with suppurative epididymitis was found on follow-up examination and ultrasonography to have a testicular mass. The radical orchiectomy specimen contained an undifferentiated spindled sex cord-stromal tumor arising in the rete testis. Testicular sex cord-stromal tumors are far less common than germ cell neoplasms and are usually benign. The close relationship between sex cords and ductules of the rete testis during development provides the opportunity for these uncommon tumors to arise anatomically within the rete tesis. This undifferentiated sex cord-stromal tumor, occurring in a previously unreported location, is an example of an unusual lesion mimicking an intratesticular malignant neoplasm

Musculoskeletal pain, a possible indicator of central sensitization, is positively associated with lower urinary tract symptom progression in community dwelling older men.

BackgroundMusculoskeletal pain, a possible marker of central sensitization, is associated with higher prevalence of lower urinary tract symptoms (LUTS) among older men. We investigated whether musculoskeletal pain is associated with LUTS progression.MethodsParticipants were 5,569 men age ≥65 years enrolled in the prospective, multicenter Osteoporotic Fractures in Men (MrOS) Study. Self-reported musculoskeletal pain within 12 months before baseline was categorized as any pain and multi-location pain. Pain interference within 4 weeks of baseline was assessed with the SF-12 questionnaire. LUTS were assessed repeatedly with the American Urological Association Symptom Index (AUA-SI). Men with severe LUTS at baseline were excluded. LUTS progression was defined as the first occurrence of a ≥4-point AUA-SI increase during a two-year follow-up interval. Incidence rate ratios (IRR) and 95% confidence intervals (CI) were estimated using multivariable pooled logistic regression.ResultsLUTS progression was 37% higher among men with any musculoskeletal pain compared to men without pain (IRR 1.37, 95%CI: 1.21,1.54). Positive associations were also observed between LUTS progression and pain at 1 (IRR 1.31, 95%CI: 1.13,1.48) and ≥2 locations (IRR 1.42, 95%CI: 1.24,1.60). Compared to men without pain interference, men with quite a bit/extreme pain interference were most likely to experience LUTS progression (minimal interference IRR 1.15, 95%CI: 1.03,1.26; moderate interference IRR 1.28, 95%CI: 1.11,1.45; quite a bit/extreme interference IRR 1.47, 95%CI:1.22,1.71).ConclusionsAmong men initially without severe LUTS, musculoskeletal pain is associated with an increased risk of LUTS progression. Studies using validated measures of central sensitization and LUTS progression among men are warranted

Lower urinary tract symptoms are associated with musculoskeletal pain among older men: Preliminary evidence for central sensitization as a mechanism?

AimsFeatures of central sensitization (CS) are present in almost all chronic pain conditions, including painful urinary conditions and back pain. Recently CS was proposed as a mechanism of nonpainful lower urinary tract symptoms (LUTS). Using musculoskeletal pain as an indicator of CS, we investigated whether the prevalence of musculoskeletal pain is greater among community-dwelling men with moderate or severe LUTS compared to those with mild LUTS.MethodsWe conducted a cross-sectional study of 5966 men ≥65 years who attended the Osteoporotic Fractures in Men Study baseline visit. LUTS were assessed with the American Urological Association Symptom Index (AUA-SI) and categorized as none/mild (0-7), moderate (8-19), or severe (≥20). Self-reported back, neck, hip, or knee pain within the 12 months before baseline was categorized as any pain and multilocation pain. We tested our hypothesis using odds ratios (OR) and 95% confidence intervals (CI) estimated from multivariable logistic regression models.ResultsThe adjusted odds of any pain were higher among men with moderate (OR 1.49, 95% CI: 1.29-1.72) and severe LUTS (OR 1.76, 95% CI: 1.28-2.40) compared to those with no/mild LUTS. The adjusted odds of pain at ≥ 2 locations were 69% higher among men with moderate (OR 1.69, 95% CI: 1.45-196) and more than double among men with severe LUTS (OR 2.24, 95% CI: 1.62-3.10) compared to men with no/mild LUTS.ConclusionsMusculoskeletal pain, especially at multiple locations, is associated with greater LUTS severity among older men. CS may represent a novel shared mechanism of pain and LUTS
