Article Synopsis
  • The study aimed to develop a non-contrast MRI/MRA protocol to evaluate kidney function and identify abnormalities in living kidney donors.
  • A total of 28 subjects underwent various imaging techniques, including pCASL and two MRA methods, to assess renal perfusion and visualize renal arteries.
  • The results indicated that the new protocol reliably assessed kidney function within 10 minutes, avoiding risks associated with contrast agents and radiation.

Aneurysmal rupture in the aortoiliac segment is a severe, life-threatening condition. Nowadays, in addition to surgical treatment, the implantation of a covered stent graft constitutes a feasible, minimally invasive treatment option. A novel approach is the add-on of transarterial aneurysm sac embolization with N-butyl-cyanoacrylate (NBCA).

Background: Multiple descriptive studies have been published on refracture patterns, particularly for forearm fractures. However, few large cohorts have been analyzed quantitatively including the odds of refracture, and with a comprehensive assessment of the possible predictive factors associated with refracture. This study aimed to assess the frequency and timing of upper extremity refracture in a large pediatric orthopaedics practice, and to evaluate the strength of association of various patient-level and fracture-related factors with refracture.

Article Synopsis
  • The study investigates the treatment options for pediatric ganglion cysts, comparing surgical and nonsurgical methods, including observation, aspiration, and orthosis, in terms of cyst resolution rates.
  • Results showed that surgical excision was the most effective treatment, achieving a cyst resolution rate of 73%, while observation alone had a 44% resolution rate, significantly higher than aspiration at 18%.
  • The findings indicate that nonsurgical interventions, such as aspiration and orthosis, do not significantly improve cyst resolution rates compared to observation alone, and highlight that older patients (over 10 years) tend to have lower resolution rates with observation.

When the lower frequency OH stretching fundamental of a water molecule is shifted to the 3500 cm spectral range by the solvation of a carbonyl compound, in this case a ketone, its infrared intensity is shared with a dark state. It is shown by chemical and isotope substitution for more than a dozen systems that the location of this resonance is remarkably substitution-independent. Harmonic and anharmonic model calculations support its assignment to a combination of the water bending overtone and in-plane water libration.
