Tendinitis cálcica atraumática de tendón extensor común del dedo medio: un caso infrecuente de dolor metacarpofalángico / Atraumatic calcium tendonitis of common extensor tendon of the middle finger: a rare case of metacarpophalangeal pain

Calcific tendinitis is a pathology characterized by the deposits of periarticular hydroxyapatite. Its pathophysiology is not completely known. It is clinically characterized by important inflammatory changes with incapacitating pain. It most commonly affects the shoulder joint and it rarely affects the hand and wrist. Given the unusual nature of this localization, we present the clinical case of a woman who developed calcific tendinitis of the third metacarpophalangeal muscle. We present the clinical evolution of the case, the treatments carried out, and a review of the literature related to this unusual localization of calcific tendinitis.

Tumor de nervio periférico: una localización poco habitual / Peripheral nerve tumor: an unusual location

Benign tumors of peripheral nerves called Schwannomas or neurilemomas, correspond to a rare pathology, represent 5% of all tumors of the upper extremity, and affects, mainly, the ulnar nerve. The incidence of Schwannoma in the literature for the radial nerve is not clearly established given the infrequency of its presentation, there are only reports of isolated cases The following publication presents the case of a male patient with a radial nerve schwannoma. Clinically, presents increased painful volume on palpation, well delimited, of soft consistency in the distal third of the right arm of 3 years of evolution, without history of previous trauma, without irradiation, or paresthesia, with preservation of motor and sensory function of radial, median and ulnar nerve. Considering that the involvement of the radial nerve is very low frequency, a review is carried out in PubMed, in the last 10 years, there are only 9 studies, grouped in case reports and imaging studies for diagnosis.

Pulpotomía con biodentine comparado con formocresol en pacientes con dentición primaria / Biodentine versus formocresol for pulpotomy in primary teeth

RESUMEN: Introducción: En dentición primaria, la pulpotomía con formocresol ha sido convencionalmente utilizada para el tratamiento de caries cercanas a la pulpa. Sin embargo, la seguridad de este material ha sido cuestionada. Por otro lado, el biodentine ha sido propuesto como un biomaterial sustituto bioactivo de la dentina, pero no está clara su efectividad. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y una tabla GRADE para el resumen de los resultados. Resultados y conclusiones: Identificamos tres revisiones sistemáticas que en conjunto incluyeron dos estudios primarios, ambos correspondientes a ensayos aleatorizados. Concluimos que no se puede establecer con claridad si biodentine comparado con formocresol aumenta el éxito clínico y el éxito radiográfico en pulpotomía en pacientes con dentición primaria, debido a que la certeza de la evidencia existente ha sido evaluada como muy baja.

ABSTRACT: Introduction: Pulpotomy with formocresol is the main treatment protocol following carious pulp exposure in primary teeth, but many concerns have been raised regarding its safety. Biodentine has been proposed as a bioactive dentine substitute, but there is still uncertainty regarding its effectiveness. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified three systematic reviews including two studies overall, of which both were randomized trials. We are uncertain whether biodentine compared to formocresol for pulpotomy improves clinical and radiographic success, as the certainty of the evidence has been assessed as very low.
