How to perform a gynaecological ultrasound in the paediatric or adolescent patient

Accuracy of doppler assessment of the uterine arteries for the diagnosis of pubertal onset in girls: a scoping review

The uterine artery pulsatility index (PI) assessed by Doppler ultrasound reflects the impedance to the blood flow in the vessel distal to the sampling point. We aimed to assess the accuracy of the uterine artery PI for the diagnosis of puberty in girls. A PRISMA-ScR-compliant scoping review was performed in the MEDLINE and Embase databases with the search terms "puberty" and "Doppler ultrasonography". Studies that included girls aged 0-18 years who underwent pelvic Doppler ultrasound with calculation of uterine artery PI were eligible. Ten studies comprising 1385 girls aged 1.2-18 years were included. The selected studies included participants from Italy, Brazil, Iran, Belgium and Denmark, and were published between 1996 and 2021. Six studies selected girls who were referred for evaluation of pubertal disorders, while four studies included only healthy girls. Nine studies found a significant difference in Doppler signal pattern and PI according to pubertal stage, with PI cutoff points ranging from 2.5 to 4.6 for the diagnosis of puberty, with a sensitivity of 77%-94%, specificity of 85%-100%, and accuracy of 79%-98%. Doppler assessment of the uterine arteries with PI calculation is a useful noninvasive tool in the diagnosis of pubertal onset in girls.

Anxiety Connected with Pelvic Ultrasound in Adolescents and Their Caregivers: Comparison of Transabdominal and Transrectal Approaches

STUDY OBJECTIVE

Transabdominal ultrasound (TAUS) is usually the first approach for diagnosis of reproductive tract complaints in all adolescents. However, there are instances when transrectal ultrasound (TRUS) is more feasible. Although TRUS is considered more invasive and distressing, evidence-based data are lacking. The aim of this study was to evaluate the level of anxiety in adolescents subjected to TAUS and TRUS and in their caregivers.

METHODS

In this cross-sectional study, data were prospectively gathered using 2 instruments: the adult or child version of the State and Trait Anxiety Inventory (STAI or STAIC) and a self-developed survey.

RESULTS

TAUS and TRUS are connected with high-level anxiety in patients and moderate anxiety in caregivers, as measured by the STAI/STAIC questionnaires. TRUS-related anxiety, fear, discomfort, and pain in adolescents are significantly higher compared with TAUS. The TRUS-related anxiety of caregivers, as well as the parent-estimated fear, discomfort, and pain of adolescents, is significantly higher compared with TAUS. Anticipated pain connected to TRUS is significantly higher than the post-exam, actually experienced pain. Pain and shame are the main reasons for adolescent anxiety connected with TRUS, whereas shame and unknown experience contribute to TAUS-related anxiety.

CONCLUSION

Given the high level of anxiety associated with both exams, additional support should be provided to patients scheduled for any pelvic ultrasound exam. Given the even higher level of adolescent anxiety related to TRUS, specialists should be encouraged to train in TAUS and make efforts to begin with this approach. Because increased caregiver anxiety could adversely affect a child's reactions, anxiety-reducing interventions should be oriented toward the caregivers as well as the patients.

Value of ultrasonography parameters in diagnosing polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrinopathy among women of reproductive age associated with hyperandrogenism, oligo-amenorrhea, and infertility. Symptoms and their severity vary among the individuals. If the manifestation is mild, PCOS may remain undiagnosed. In more severe cases, it results in a spectrum of symptoms of metabolic syndrome, insulin resistance, and cardiovascular diseases. The diagnosis is established after a physical examination and evaluating the patient's hormonal profile. In addition to these required methods, ultrasonographic assessment of the patient's ovaries is another non-invasive, cheap, and time-saving tool, making the examination more profound and leading to the correct diagnosis. Specific ultrasonographic parameters are used to tell the healthy and polycystic ovaries apart: the ovarian volume (OV), ovarian follicle count, follicle distribution pattern, ovarian stromal echogenicity, and the resistance and pulsatility indices assessed using the Doppler function. This review evaluated the selected articles and ascertained the ultrasonographic parameters that accurately predict PCOS. This systematic review showed that the most valuable ultrasonographic parameters in diagnosing PCOS are the OV and follicle number per ovary.
