Charcot arthropathy in the spine. Experience in our centre. About 13 cases. Review of the literature. / Artropatía de Charcot en el raquis. Experiencia en nuestro centro. A propósito de 13 casos. Revisión de la literatura.

Charcot arthropathy of the spine is a neuropathic affectation of the spine, it is considered rare, has a destructive and progressive evolution. It is usually due to a previous traumatic injury, but it has also been described as secondary to other infectious or tumoural processes. Initially, surgical treatment has always been considered for possible complications such as pain control and trunk instability. We present a series of 13 cases diagnosed with Charcot arthropathy at the Institut Guttmann, in which the following variables are described: aetiology (traumatic, infectious, iatrogenic), clinical features (pain, loss of trunk control, vegetatism, spasticity), interval of onset of the clinical features, location (L2-L3), treatment (surgical or conservative) and the evolution they presented, with the aim of evaluating conservative treatment as the first option, instead of surgery. In our sample, 61.5% (8/13) were treated surgically with posterior instrumentation (7/8), except for one case which was anterior and posterior; 38.5% (5/13) were treated conservatively and none required subsequent surgery. In conclusion, our line of action would initially be to consider conservative treatment, and to use surgery for cases in which the clinical evolution was not as expected, either due to poor pain control and/or limitation of mobility secondary to the deformity limitation of mobility secondary to the deformity of the trunk, or when the spinal involvement or the patient's symptoms are not tolerated and require a quicker and more aggressive solution.

In vitro nematicidal activity of two ferrocenyl chalcones against larvae of Haemonchus contortus (L3) and Nacobbus aberrans (J2).

The main goal of this work was to evaluate the in vitro biological activity of two ferrocenyl chalcones (FcC-1 and FcC-2) against Haemonchus contortus (third-stage larvae (L3)) and Nacobbus aberrans (second-stage juveniles (J2)). Both compounds were synthesized and characterized by usual spectroscopic methods and their molecular structures were confirmed by single-crystal X-ray diffractometry. Nematode strains were examined in terms of percentage mortality of H. contortus (L3) by the action of FcC-1, which showed an effectivity of 100% at a concentration of 342 µM in 24 h, with EC50 = 20.33 µM and EC90 = 162.76 µM, whereas FcC-2 had an effectivity of 72% at a concentration of 342 µM in 24 h, with EC50 = 167.39 µM and EC90 = 316.21 µM. The effect of FcC-1 against nematode phytoparasite N. aberrans showed a better percentage of 95% at a concentration of 342 µM, with EC50 = 7.18 µM and EC90 = 79.25 µM, whereas the effect of FcC-2 was 87% at 342 µM, with EC50 = 168 µM and EC90 = 319.56 µM at 36 h. After treatment, the scanning electron micrographs revealed deformities in the dorsal flank and posterior part close to the tail of H. contortus L3. They showed moderate in vitro nematicidal activity against H. contortus L3 and N. aberrans J2.
