Diagnostic accuracy of Point Of Care UltraSound (POCUS) in clinical practice: A retrospective, emergency department based study.

AIMS: Point-of-care ultrasound (POCUS) is the acquisition and interpretation of ultrasound imaging at the bedside to solve specific clinical questions based on signs and symptoms of presentation. While several studies evaluated POCUS diagnostic accuracy for a variety of clinical pictures in the emergency department (ED), only a few data are available on POCUS diagnostic accuracy performed by physicians with different POCUS skills. The objective of this research was to evaluate the diagnostic accuracy of POCUS compared to standard diagnostic imaging in the ED. MATERIALS AND METHODS: This was a retrospective study conducted in the ED of a third-level university hospital. Patients who underwent cardiac, thoracic, abdominal, or venous lower limb POCUS and a standard imaging examination between June 2021 and January 2022 were included. RESULTS: 1047 patients were screened, and 844 patients included. A total of 933 POCUS was included (102, 12.09%, cardiac; 466, 55.21%, thoracic; 336, 39.8%, abdominal; 29, 3.44%, lower limb venous POCUS), accounting for 2029 examinations. POCUS demonstrated 96.6% (95% CI 95.72-97.34) accuracy, 47.73 (95% CI 33.64-67.72) +LR, 0.09 (95% CI 0.06-0.12) -LR. +LR was greater than 10 for all investigations but for hydronephrosis (5.8), and -LR never exceeded 0.4. CONCLUSIONS: POCUS exhibited high diagnostic accuracy for virtually all conditions when performed by emergency department physicians.

Reproductive outcome in patients treated and not treated for idiopathic early puberty: long-term results of a randomized trial in adults.

OBJECTIVE: To evaluate the adult reproductive outcome in girls with early puberty who participated in a previous random study. STUDY DESIGN: A total of 22 subjects treated with triptorelin 3.75 mg every 4 weeks (group 1), 18 subjects not treated (group 2), and 22 age-matched normal volunteers (control group) underwent a physical examination, serum hormone level determination, and pelvic ultrasonography. RESULTS: The characteristics of menstrual cycles, serum hormone levels, and ultrasound results did not differ significantly among the 3 groups examined. The mean ovarian volume and the uterine volume tended to increase in the subjects of group 2, but the differences were not significant. The percentage of subjects who reported being sexually active at the time of the examination was greater in the 2 groups with previous early puberty than in the controls (76% of cases in group 1, 72% in group 2, and 59% in the control group). CONCLUSIONS: Neither early puberty nor its treatment seems to significantly affect the normal adult function of the pituitary-gonadal axis.
