Turner Syndrome with Mosaicism of X Chromosome: A Case Report.

Turners' syndrome, although common, is a complex syndrome that requires a multidisciplinary team to manage it. If undiagnosed prenatally or in childhood, Turners' syndrome females often present later to gynaecologists with premature ovarian insufficiency or infertility as their primary presenting complaint. Timely diagnosis and management are key to improving health outcomes in women with Turners' syndrome, as it is associated with multiple comorbidities which left untreated will result in excess morbidity and mortality. We hereby present a case of a 20-year-old female diagnosed to have Turner's syndrome with mosaicism of the X chromosome to highlight the wide array of clinical presentations it can have. Keywords: case reports; infertility; sex chromosome aberrations; Turner syndrome.

Herlyn-Werner-Wunderlich Syndrome: A Case Report.

Herlyn-Werner-Wunderlich syndrome is a rare Mullerian and mesonephric ductal anomaly characterized by a triad of didelphys uterus, obstructed hemivagina, and ipsilateral renal agenesis complex. This entity is also known as obstructed hemivagina and ipsilateral renal anomaly. We present a case of a 24-year-old nulliparous female with Herlyn-Werner-Wunderlich who presented with dysmenorrhea and intermenstrual bleeding. The diagnosis was initially made through ultrasound and confirmed on magnetic resonance imaging. The nonspecific nature of symptoms and variability in presentation depending on the classification and type of Herlyn-Werner-Wunderlich syndrome often leads to misdiagnosis or a delay in diagnosis. Therefore, a high index of suspicion is required. Keywords: case reports; mesonephric ducts; mullerian ducts.

Subterahertz spin pumping from an insulating antiferromagnet.

Spin-transfer torque and spin Hall effects combined with their reciprocal phenomena, spin pumping and inverse spin Hall effects (ISHEs), enable the reading and control of magnetic moments in spintronics. The direct observation of these effects remains elusive in antiferromagnetic-based devices. We report subterahertz spin pumping at the interface of the uniaxial insulating antiferromagnet manganese difluoride and platinum. The measured ISHE voltage arising from spin-charge conversion in the platinum layer depends on the chirality of the dynamical modes of the antiferromagnet, which is selectively excited and modulated by the handedness of the circularly polarized subterahertz irradiation. Our results open the door to the controlled generation of coherent, pure spin currents at terahertz frequencies.
