AI Article Synopsis

  • Turner’s syndrome (TS) is a condition caused by the complete or partial absence of an X chromosome, affecting about 1 in 2200 live-born females, often diagnosed through karyotype analysis due to issues like pregnancy loss or IVF failures.
  • In a case involving a 32-year-old patient who underwent IVF after ICSI-PGD and was diagnosed with a 45X/46XX karyotype, a fetal anomaly (upper limb hemimelia) was detected at the 12-week scan, leading to the termination of that fetus.
  • The case highlights the increased risk of fetal anomalies in mosaic TS pregnancies, emphasizing the need for careful prenatal monitoring even with selected normal karyotype embryos.

Article Abstract

Turner's syndrome (TS) is depicted as a total or partial absence of X chromosome, and occurs in approximately 1/2200 of live born females. Generally, mosaic patients are diagnosed following karyotype analysis due to recurrent pregnancy loss, repeated in vitro fertilization (IVF) failure, and a history of malformed babies. The purpose of this case report is to show that even a selection of normal karyotype embryos can result in abnormalities for those with mosaic TS. A 32-year old patient who underwent IVF after ICSI-PGD, and was diagnosed with 45X/46XX karyotype. At the 12-week scan, one of the fetuses had an upper limb hemimelia in one arm, and feticide was applied to that fetus. The patient delivered a healthy, 2980 g female baby at the thirty-eighth week. In mosaic TS pregnancies (even those obtained by ICSI-PGD), fetal anomaly risk is high. Therefore, careful prenatal scanning is needed for these pregnancies.

the evolution of axillary management in breast cancer has witnessed significant changes in recent decades, leading to an overall reduction in surgical interventions. There have been notable shifts in practice, aiming to minimize morbidity while maintaining oncologic outcomes and accurate staging for newly diagnosed breast cancer patients. These advancements have been facilitated by the improved efficacy of adjuvant therapies.

the axillary reverse mapping (ARM) procedure aims to preserve the lymphatic drainage structures of the upper extremity during axillary surgery for breast cancer, thereby reducing the risk of lymphedema in the upper limb. Material and this prospective study included 57 patients with breast cancer who underwent SLNB and ARM. The sentinel lymph node (SLN) was identified using a radioactive tracer.

Evaluation of the Short-Term Restorative Care program: Effects on physical functioning.

Australas J Ageing

December 2024

School of Nursing, Centre for Healthcare Transformation, Faculty of Health, Queensland University of Technology, Brisbane, Queensland, Australia.

Objective: The Short-Term Restorative Care program is an 8-week multidisciplinary early intervention funded by the Australian Government that aims to reverse or slow the functional decline of older Australians. Despite the large investment of tax-payer money to fund the program, very little peer-reviewed literature exists examining the ability of the program to deliver on its aims.

Methods: This was a retrospective cohort study.

Purpose: This study aimed to explore the potential application of NAO in guiding patients through rehabilitative exercises using external audiovisual stimuli, focusing on temporospatial control in terms of range of motion (ROM), execution time and movement smoothness.

Methods: This is a preliminary analysis involving ten healthy volunteers and two patients with shoulder musculoskeletal disorders. The protocol was developed in two phases (III and IV) with different ROM limits and including flexion-extension (FE), external-rotation (ER) and internal-rotation (IR) exercises, performed at two speeds and both with and without NAO assistance.
