Benign Evolution of Complex Regional Pain Syndrome (CRPS) Type 1 in Patients Treated with Intravenous Neridronate: A Single-Center Real-Life Experience.

Objective: To investigate the long-term effects of intravenous neridronate treatment in patients with complex regional pain syndrome type 1 (CRPS) in a real-life setting.

Methods: We conducted a retrospective study on consecutive CRPS patients treated at our hospital from February 2018 to July 2023. All were treated within three months of the onset of CRPS symptoms.

Osteitis condensans ilii: prevalence and characteristics of a neglected mimic of sacroiliitis.

Objectives: Osteitis condensans ilii (OCI) is a benign condition characterised by triangular sclerosis of the iliac bone which may mimic radiographic sacroiliitis. Prevalence is estimated between 0.9 and 2.

General Relativity from Scattering Amplitudes.

Weoutline the program to apply modern quantum field theory methods to calculate observables in classical general relativity through a truncation to classical terms of the multigraviton, two-body, on-shell scattering amplitudes between massive fields. Since only long-distance interactions corresponding to nonanalytic pieces need to be included, unitarity cuts provide substantial simplifications for both post-Newtonian and post-Minkowskian expansions. We illustrate this quantum field theoretic approach to classical general relativity by computing the interaction potentials to second order in the post-Newtonian expansion, as well as the scattering functions for two massive objects to second order in the post-Minkowskian expansion.

[Fanconi's anemia type Estren-Dameshek. A case report (author's transl)].

A clinical, hematological and cytogenetical study has been carried out in a patient with Fanconi's anemia. The absence of phenotypical alterations at clinical and instrumental surveyor suggested a frame in a variant type Estren-Dameshek. The genetical problem between the classical and variant form is not yet established.
