Síndrome del túnel tarsiano: a propósito de un caso
1995
El Síndrome del túnel tarsiano está causado por el atrapamiento del nervio tibial posterior o sus ramas a nivel del retináculo flexor en el tobillo. Se describe un caso de síndrome de túnel tarsiano causado por un quiste sinovial. El paciente refería dolor desde hacía 1 mes a nivel retromaleolar irradiado a planta del pie y primer dedo. Al mes de iniciado los síntomas se apreció una tumoración a nivel retromaleolar. Se exponen los hallazgos EMG, ecografía y R.M.N. Cuando la causa de esta entidad es una lesión ocupante de espacio, está indicada la cirugía, siendo el pronóstico mejor cuanto más precoz es la intervención. Tarsal tunnel syndrome is an entrapment neuropathy caused by compression…
Parálisis del nervio interóseo posterior tras luxación posterolateral de codo
1998
Se presenta un infrecuente caso clínico de parálisis del nervio interóseo posterior en asociación con luxación de codo. La discusión argumenta sobre la patogenia y bases anatómicas que pueden justificar esta asociación. We report an uncommon case of posterior interosseus nerve palsy in association with an elbow dislocation. The authors discuss about the mechanism and anatomical basis of this lesion.
Osteoma osteoide de localización escapular: descripción de un caso
2012
Presentamos el caso de un paciente, con dolor en el hombro de predominio nocturno y que diagnosticamos como Osteoma Osteoide localizado en la escápula izquierda. El tratamiento con salicilatos no fue efectivo para mejorar el dolor y se procedió a la resección abierta y cauterización de la lesión. El resultado fue satisfactorio y actualmente el paciente permanece asintomático. We report a case of a patient with pain worse at night, located at the elbow. Osteoid Osteoma of the scapula was diagnosed. Pain was not relieved by Salycilates. Open surgical treatment and cauterization were the treatment elected in our case. Pain regressed inmediatly after surgery and the patient was asimptomatic sin…
Microstructural assessment of rodent behavior in the hole-board experimental assay
2010
The aim of the present methodological article was to assess whether a microstructure of hole-exploratory activity can be demonstrated in rats tested in the hole-board, an experimental assay widely used to study anxiety-related behaviors in rodents. Six never properly described hole exploratory behavioral components were identified: active-dip, static-dip, rapid-dip, circular-sniff, point-sniff and central-sniff. Results, assessed by means of descriptive and multivariate approaches, reveal a complex microstructural organization of these behavioral elements. The hypothesis of an important role of the relationships between point-sniff and head dipping activities, in anxiety-related hole explor…
Der Supinatorfettkörper bei Frakturen des Ellbogengelenkes
1989
The position of the supinator fat pad is regarded as a valuable sign in fractures of the elbow. In our patients the pad was visible in 277 out of 337 cases (82%). The sign was positive in only 27 out of 55 proximal fractures of the radius (sensitivity 0.49). There was no correlation between the severity of the fracture and the sign. There was marked variation in the distance between the pad and the radius, depending on age, build and projection. Our results indicate that the sign is not suitable for the diagnosis of fracture of the elbow.
Fine adaptive control of precision grip without maximum pinch strength changes after median nerve mobilization
2020
ABSTRACTFine dexterity critically depends on information conveyed by the median nerve. While the effects of its compression and vibration are well characterized, little is known about longitudinal tension and excursion. Using a force-sensitive manipulandum, a numeric dynamometer and Semmes-Weinstein monofilaments, we examined the adaptations of precision grip control, maximum pinch strength and fingertips pressure sensation threshold before and immediately after the application of longitudinal tension and excursion mobilizations applied on the median nerve. Grip (GF) and load (LF) forces applied by the thumb, index and major fingers were collected in 40 healthy young participants during thr…
Intravenous Regional Anesthesia
1988
Intravenous regional anesthesia was first described by Bier in 1908. The technique fell into disuse until 1963, when Holmes revived the technique by substituting lidocaine for procaine (see Sect. V. D, “Choice and Dosage of Agents”).
Smart switching in feedforward control of grip force during manipulation of elastic objects
2017
AbstractSwitching systems are common in artificial control systems. Here, we suggest that the brain adopts a switched feedforward control of grip forces during manipulation of objects. We measured how participants modulated grip force when interacting with soft and rigid virtual springs when stiffness varied nearly continuously between trials. We identified a sudden phase transition between two forms of feedforward control that differed in the timing of the synchronization between the anticipated load force and the applied grip force. The switch occurred several trials after a threshold stiffness level. These results suggest that in the control of grip force, the brain acts as a switching c…
Papular-purpuric gloves-and-socks syndrome : presentation of a clinical case
2007
Papular-Purpuric Glove-and-Sock Syndrome is a rare, infectious disease, of viral etiology, characterized by the presence of pruritus, edema and symmetrical erythema, very well defined at the wrists and ankles with a gloves-and-socks distribution. Other areas can be affected, with a moderate erythema appearing in cheeks, elbows, knees, armpits, abdomen, groin, external genitalia, internal face of the thighs and the buttocks. Erosions, small ulcers, enanthema and blisters can be observed in the oral cavity and lips, and less frequently in other mucous membranes. Complications are rare, although they can be severe, 50% of the published cases are related with the Parvovirus B19. Due to its oral…
Una causa inusual de dolor en el pulgar: : osteoma osteoide de la falange proximal del pulgar
2018
Osteoid osteoma located in the hand is a rare clinical entity that is often confused with other bone diseases such as osteomyelitis, enchondroma or intraosseous epidermoid cyst. At the level of the hand, the diagnosis is not always obvious, given that the clinical and radiographic findings are usually unusual. Definitive treatment usually requires surgical resection of the lesion by curettage or block excision. We describe the clinical case of a 16-year-old adolescent patient with an osteoid osteoma of uncommon location at the level of the proximal phalanx of the thumb and without the clinical and typical radiographic appearance of the same, which made it difficult to diagnose it, as well a…
