Asian J Androl 2022 Jun 10. Epub 2022 Jun 10.

Department of Ultrasound, Zhongshan Hospital, Fudan University, Institute of Ultrasound in Medicine and Engineering, Shanghai 200032, China.

The purpose of this study was to evaluate the diagnostic performance of multiparametric ultrasound (mpUS; grayscale US, color Doppler US, strain elastography, and contrast-enhanced US) in the assessment of testicular lesions with negative tumoral markers. MpUS imaging data, patient age, serum tumor markers, scrotal pain, cryptorchidism, and related clinical information were retrospectively collected for patients who underwent mpUS examination between January 2013 and December 2019. Histologic results or follow-up examinations were used as the reference standard. Read More

Role of Testicular Scintigraphy in the Assessment of Viability of Undescended Testis: Potential Pitfalls and Complementary Role of 18F FDG PET/CT.

Clin Nucl Med 2022 Jul 29;47(7):e496-e497. Epub 2022 Apr 29.

From the Departments of Nuclear Medicine.

Abstract: Doppler ultrasonography and testicular scintigraphy are sensitive techniques to detect the adequacy of blood flow to testicular tissue. Because Doppler ultrasonography is an operator-dependent imaging modality, it can result in equivocal findings. Testicular scintigraphy proves to be more accurate in such cases, but it may be inconclusive on occasion. Read More

Persistent Mullerian Duct Syndrome: A Rare Case of an Adult Infertile Male with Bilateral Cryptorchidism.

J Reprod Infertil 2021 Jul-Sep;22(3):216-219

- Department of Urology, Grant Government Medical College and Sir JJ Hospital, Mumbai, India.

Background: Persistent mullerian duct syndrome (PMDS) is a very rare form of internal male pseudohermaphroditism in individuals who are phenotypically males with 46 XY karyotypes harboring internal female reproductive organs which are Mullerian derivatives. It occurs as a defect in the genes coding for the Mullerian inhibiting substance (MIS) or the anti Mullerian hormone (AMH) receptor, ultimately leading to failure of regression of Mullerian ducts.

Medical examination revealed a 46XY karyotype, a primary amenorrhea and an appropriate testosterone increase after HCG stimulation test. The patient was diagnosed then with a 46,XY disorder of sex development with androgen insensitivity syndrome, but then he missed subsequent appointments. Read More

Andrology 2022 02 27;10(2):262-269. Epub 2021 Sep 27.

DEFE, Univ Toulouse, Université Toulouse III, Paul Sabatier, INSERM, Toulouse, France.

Background: Congenital unilateral absence of vas deferens has been diagnosed in fertile and normozoospermic males and is associated with the risk of unilateral renal absence or cystic fibrosis transmembrane conductance regulator mutations; but no prediction model currently exists to diagnose this condition.

Transl Pediatr 2021 Jun;10(6):1748-1754

Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, China.

Arboleda-Tham syndrome (OMIM#616268) is a newly named neurodevelopmental disorder, which is an autosomal dominant hereditary disease characterized by genetic variants. The clinical manifestations include global developmental delay, primary microcephaly, and craniofacial dysmorphism, as well as more varied features such as feeding difficulties, cardiac defects, and ocular anomalies. Currently, due to restricted knowledge of Arboleda-Tham syndrome and less specific pathological manifestations, it is difficult to diagnose at the early stages of the disease. Read More
