The European Academy of Andrology (EAA) ultrasound study on healthy, fertile men: An overview on male genital tract ultrasound reference ranges.

BACKGROUND: So far, male genital tract color-Doppler ultrasound (MGT-CDUS) was not standardized. Recently, the European Academy of Andrology (EAA) published the results of a multicenter study assessing the CDUS characteristics of healthy-fertile men (HFM) to obtain normative parameters. OBJECTIVES: To report the EAA US study (i) standard operating procedures (SOPs) for assessing MGT-CDUS, (ii) main MGT-CDUS normative parameters, and (iii) compare the EAA and previously published "normal" CDUS values. METHODS: A cohort of 248 HFM (35.3 ± 5.9 years) was studied, evaluating MGT-CDUS before and after ejaculation following SOPs. RESULTS: SOPs for MGT-CDUS assessment are summarized here. All subjects underwent scrotal CDUS and 188 men underwent transrectal ultrasound before and after ejaculation. The main CDUS reference ranges and characteristics of the HFM-MGT are reported here. The mean testicular volume was ∼17 mL. The lower limit for right and left testis was 12 and 11 mL, defining testicular hypotrophy. The upper limit for epididymal head, body, tail, and vas deferens was 11.5, 5, 6, and 4.5 mm, respectively. Testicular and epididymal arterial reference ranges are reported. The EAA varicocoele classification is reported. CDUS-varicocoele was detected in ∼37% of men. Prostate mean volume was ∼25 mL, while lower and upper limits were 15 and 35 mL, defining hypotrophy and enlargement, respectively. Prostate arterial reference ranges are reported. Prostate calcifications and inhomogeneity were frequent; midline prostatic cysts were rare and small. Ejaculatory duct abnormalities were absent. The upper limit for periprostatic venous plexus was 4.5 mm. Lower and upper limits of seminal vesicles (SV) anterior-posterior diameter were 6 and 16 mm, defining hypotrophy or dilation, respectively. Seminal vesicle volume and ejection fraction reference ranges are reported. SV-US abnormalities were rare. Deferential ampullas upper limit was 6 mm. A discussion on the EAA and previously published "normal" CDUS values is reported here. CONCLUSIONS: The EAA findings will help in reproductive and general male health management.

The European Academy of Andrology (EAA) ultrasound study on healthy, fertile men: Prostate-vesicular transrectal ultrasound reference ranges and associations with clinical, seminal and biochemical characteristics.

BACKGROUND: Transrectal ultrasound (TRUS) parameters are not standardized, especially in men of reproductive age. Hence, the European Academy of Andrology (EAA) promoted a multicenter study to assess the TRUS characteristics of healthy-fertile men (HFM) to establish normative parameters. OBJECTIVES: To report and discuss the prostate and seminal vesicles (SV) reference ranges and characteristics in HFM and their associations with clinical, seminal, biochemical parameters. METHODS: 188 men (35.6 ± 6.0 years) from a cohort of 248 HFM were studied, evaluating, on the same day, clinical, biochemical, seminal, TRUS parameters following Standard Operating Procedures. RESULTS: TRUS reference ranges and characteristics of the prostate and SV of HFM are reported herein. The mean PV was ∼25 ml. PV lower and upper limits were 15 and 35 ml, defining prostate hypotrophy and enlargement, respectively. PV was positively associated with age, waistline, current smoking (but not with T levels), seminal volume (and negatively with seminal pH), prostate inhomogeneity, macrocalcifications, calcification size and prostate arterial parameters, SV volume before and after ejaculation, deferential and epididymal size. Prostate calcifications and inhomogeneity were frequent, while midline prostatic cysts were rare and small. Ejaculatory duct abnormalities were absent. Periprostatic venous plexus size was positively associated with prostate calcifications, SV volume and arterial peak systolic velocity. Lower and upper limits of SV anterior-posterior diameter after ejaculation were 6 and 16 mm, defining SV hypotrophy or dilation, respectively. SV total volume before ejaculation and delta SV total volume (DSTV) positively correlated with ejaculate volume, and DSTV correlated positively with sperm progressive motility. SV total volume after ejaculation was associated negatively with SV ejection fraction and positively with distal ampullas size. SV US abnormalities were rare. No association between TRUS and time to pregnancy, number of children or history of miscarriage was observed. CONCLUSIONS: The present findings will help in better understanding male infertility pathophysiology and the meaning of specific TRUS findings.

The European Academy of Andrology (EAA) ultrasound study on healthy, fertile men: clinical, seminal and biochemical characteristics.

BACKGROUND: Infertility affects 7%-12% of men, and its etiology is unknown in half of cases. To fill this gap, use of the male genital tract color-Doppler ultrasound (MGT-CDUS) has progressively expanded. However, MGT-CDUS still suffers from lack of standardization. Hence, the European Academy of Andrology (EAA) has promoted a multicenter study ("EAA ultrasound study") to assess MGT-CDUS characteristics of healthy, fertile men to obtain normative parameters. OBJECTIVES: To report (a) the development and methodology of the "EAA ultrasound study," (b) the clinical characteristics of the cohort of healthy, fertile men, and (c) the correlations of both fertility history and seminal features with clinical parameters. METHODS: A cohort of 248 healthy, fertile men (35.3 ± 5.9 years) was studied. All subjects were asked to undergo, within the same day, clinical, biochemical, and seminal evaluation and MGT-CDUS before and after ejaculation. RESULTS: The clinical, seminal, and biochemical characteristics of the cohort have been reported here. The seminal characteristics were consistent with those reported by the WHO (2010) for the 50th and 5th centiles for fertile men. Normozoospermia was observed in 79.6% of men, while normal sperm vitality was present in almost the entire sample. Time to pregnancy (TTP) was 3.0[1.0-6.0] months. TTP was negatively correlated with sperm vitality (Adj.r =-.310, P = .011), but not with other seminal, clinical, or biochemical parameters. Sperm vitality and normal morphology were positively associated with fT3 and fT4 levels, respectively (Adj.r = .244, P < .05 and Adj.r = .232, P = .002). Sperm concentration and total count were negatively associated with FSH levels and positively, along with progressive motility, with mean testis volume (TV). Mean TV was 20.4 ± 4.0 mL, and the lower reference values for right and left testes were 15.0 and 14.0 mL. Mean TV was negatively associated with gonadotropin levels and pulse pressure. Varicocoele was found in 33% of men. CONCLUSIONS: The cohort studied confirms the WHO data for all semen parameters and represents a reference with which to assess MGT-CDUS normative parameters.

Role of hemodialysis with high cut-off membranes in a patient with a non-recognized leishmaniasis.

BACKGROUND: We report here a case of a woman affected by fever, weight loss, splenomegaly, and leucopenia associated with trombocytopenia, transferred to the intensive care unit with acute kidney injury and septic shock. METHODS: Patient was treated with high cut-off continuous veno-venous hemodialysis (HCO-CVVHD). RESULTS: During treatment, the patient experienced a stable improvement in the hemodynamic, pulmonary function and tissue perfusion parameters. After 48 h of treatment, significant reductions in SOFA score (from 12, before starting the procedure, to 6) and in serum inflammatory mediators (as IL-6, from 599-568 pg/ml) were observed. Leishmania infection was identified as responsible of the septic condition only 48 h after removing hemodialysis. Antiprotozoal therapy was begun and the patient discharged. CONCLUSIONS: By supporting the renal function and reducing systemic inflammation, HCO-CVVHD could be a useful bridge therapy. This procedure allowed the medical team to gain sufficient time to diagnose the type of infection and begin an etiological therapy.

[Severe recurrent intrahepatic cholestasis in systemic AL amyloidosis without obvious liver involvement: unexplained hepatic toxicity or a case of misdiagnosed liver amyloidosis?]. / Colestasi intraepatica in corso di amiloidosi sistemica AL senza evidenza istologica di un coinvolgimento epatico: un caso di epatopatia tossica o una mancata diagnosi di amiloidosi epatica?

We report the case of a 50-year-old woman who was admitted to the hospital for acute abdominal pain with nephrotic proteinuria, rapidly progressive renal failure, and moderate anemia. Laboratory tests showed mild Bence Jones (λ) proteinuria with negative serum immunofixation and a mild increase in λ free light chains. A bone marrow biopsy and a fat tissue aspirate showed multiple myeloma and amyloidosis. Because of the end-stage renal disease, the patient began regular dialysis treatment and was started on bortezomib 1.3 mg/m2 plus dexamethasone 40 mg on days 1, 4, 8 and 11 of 21-day cycles. Ten days later she complained of a new episode of abdominal pain with jaundice. A CT scan and an MRI scan ruled out all secondary causes of cholangitis including cancer. Acute intrahepatic cholestasis due to amyloid deposition was then hypothesized. After 4 well tolerated cycles of bortezomib and dexamethasone, blood tests showed a complete hematological response with full reversal of cholestasis. After three months, a new episode of abdominal pain occurred and this time the patient was operated on and found to have an intestinal volvulus. Because of the jaundice, a transjugular liver biopsy was performed showing no evidence of amyloid deposits. Two months later the patient died of septic shock. Although no autopsy was performed and the ultimate cause of the cholestasis could not be ascertained, amyloidosis remains the major culprit in this unfortunate case.
