AbstractMan's need for artificial replacements to supply missing or lost body parts has probably existed as long as man himself. Body abnormalities or defects compromise appearance, function and render an individual incapable of leading a relatively normal life. Extraoral defects involving ear, eye, nose, finger and few others are commonly encountered. Prosthetic restoration of these facial defects is an ancient art, in which success has always been limited due to the unavailability of adequate materials or because the available materials do not fulfil the ideal requirements. The most accepted materials today are the silicones because of their better esthetics.This paper presents prosthetic rehabilitation of the distal phalynx of left index finger with custom-made silicone prosthesis.

ABSTRACT Amputation of a finger will have considerable functional and psychological impact on an individual. Although prosthetic rehabilitation incorporating implants is considered an ideal treatment option, the patient may not give consent due to apprehension toward surgical procedures. The ideal prosthesis should replace the missing part of the finger so precisely that it would not draw the attention of the observer. Fabrication of such a prosthesis will require great technical and artistic expertise. This paper presents a case of prosthetic rehabilitation of an amputated finger using a silicone finger prosthesis. How to cite this article Fernandez T, Harshakumar K, Ravichandran R.

And Function

Background: Each organ serves a specific function in the human body. Congenital absence or loss of even minor parts of it can pose extreme psychological trauma in addition to the functional impairment and esthetic issues encountered by the individual. Amputation of complete or a part of phalange of hand is frequently encountered either due to trauma or necrosis. Restoration of such defects become mandatory to improve general form and function combined with the esthetic requirements of the patient. It can either be done by microvascular reconstruction or prosthetic rehabilitation. The latter becomes the means of choice in cases where the former is either not possible, unavailable, unsuccessful, or unaffordable. Case Report: A case report has been presented of a 60 years old patient with an old traumatic partially amputated index finger. Treatment Plan: A custom-made glove-type prosthesis was fabricated using silicone elastomer. Conclusion: A ring is provided for better esthetics and special adhesive is recommended for retention of the prosthesis.

AbstractA self-generated touch feels less intense than an external touch of the exact same intensity. According to a prevalent computational theory of motor control, this attenuation occurs because the brain uses internal forward models to predict the somatosensory consequences of our movements using a copy of the motor command, i.e., the efference copy. These tactile predictions are then used to suppress the perceived intensity of the actual tactile feedback. Despite being highly influential, the core assumption of theory has never been tested; that is, whether the efference copy is necessary for somatosensory attenuation. A possible alternative hypothesis is that a predictable contact of two of one’s own body parts is sufficient. Using a psychophysical task, we quantified the attenuation of touch applied on the participants’ left index finger when the touch was triggered by the active or passive movement of the participants’ right index finger and when it was externally generated in the absence of any movement. We observed somatosensory attenuation only when the touch was triggered by the voluntary movement of the participants’ finger. In contrast, during the passive movement, the intensity of the touch was perceived to be as strong as when the touch was externally triggered. In both active and passive movement conditions, the participants showed the same discrimination capacity. Electromyographic recordings confirmed minimal activity of the right hand during the passive movement. Together, our results suggest that the efference copy is necessary for computing the somatosensory predictions that produce the attenuation of self-generated touch.

AbstractAction preparation involves widespread modulation of motor system excitability, but the precise mechanisms are unknown. In this study, we investigated whether intracortical inhibition changes in task-irrelevant muscle representations during action preparation. We used transcranial magnetic stimulation (TMS) combined with electromyography in healthy human adults to measure motor evoked potentials (MEPs) and cortical silent periods (CSPs) in task-irrelevant muscles during the preparatory period of simple delayed response tasks. In Experiment 1, participants responded with the left-index finger in one task condition and the right-index finger in another task condition, while MEPs and CSPs were measured from the contralateral non-responding and tonically contracted index finger. During Experiment 2, participants responded with the right pinky finger while MEPs and CSPs were measured from the tonically contracted left-index finger. In both experiments, MEPs and CSPs were compared between the task preparatory period and a resting intertrial baseline. The CSP duration during response preparation decreased from baseline in every case. A laterality difference was also observed in Experiment 1, with a greater CSP reduction during the preparation of left finger responses compared to right finger responses. MEP amplitudes showed no modulation during movement preparation in any of the three response conditions. These findings indicate cortical inhibition associated with task-irrelevant muscles is transiently released during action preparation and implicate a novel mechanism for the controlled and coordinated release of motor cortex inhibition.New & NoteworthyIn this study we observed the first evidence of a release of intracortical inhibition in task-irrelevant muscle representations during response preparation. We applied transcranial magnetic stimulation to elicit cortical silent periods in task-irrelevant muscles during response preparation and observed a consistent decrease in the silent period duration relative to a resting baseline. These findings address the question of whether cortical mechanisms underlie widespread modulation in motor excitability during response preparation.

Abstract Background Neonatal systemic vasculitis syndromes have been reported in infants born to mothers with systemic lupus erythematosus, Sjögren’s syndrome, Behҫet’s disease, cutaneous polyarteritis nodosa and anti-neutrophil cytoplasmic antibody-associated vasculitides. Here we report a novel association of a case of new-onset maternal seronegative inflammatory arthritis associated with a transient systemic vasculitis in a neonate. Case presentation In the first 24 h of life, a preterm Caucasian baby boy was noted to have blue discoloration to all four extremities. Despite antibiotics, fresh frozen plasma and anticoagulation, the discoloration remained, particularly in the left index finger. This was associated with fever and a maximum C-reactive protein (CRP) of 148 mg/L. Intravenous immunoglobulin (IVIG) was given with short-term improvement. Initial echocardiogram showed enlarged coronary arteries with normalization on repeat 1 week later. Clinical signs and symptoms responded to high dose oral steroid administration. MRI angiography (MRA) of the body and heart showed tortuosity of arteries in the upper and lower extremities with gadolinium uptake, suggestive of vasculitis. Autoantibody profile negative. Genetic panel for hereditary autoinflammatory diseases was negative as was whole exome sequencing performed on the trio. The baby was weaned off steroids by 5 months of age. A small distal autoamputation of the left index finger occurred. He was born to a 28-year-old woman who developed new onset severe symmetrical polyarthritis at 8 weeks gestation. This was presumed a reactive arthritis secondary to a dental infection. Infectious work up and autoantibodies were negative. She was treated with high dose prednisone for the remainder of her pregnancy. The mother was weaned off prednisone, treated with hydroxychloroquine for 8 months post-partum and remains in remission. A repeat MRA done at 1 year old showed mild residual tortuosities of the arteries in the forearms. The remainder of the medium and large vessels were within normal limits with no gadolinium enhancement to suggest active disease. The child is now 4 years old with normal growth and development. Conclusion This is a unique case of new-onset seronegative presumed reactive arthritis in a mother with the rare development of a successfully treated medium vessel vasculitis in an infant.

Background: Previous studies have highlighted the particular risk of radiation exposure to the surgeon’s hands with intraoperative fluoroscopy. Although evidence exists that shielding equipment for the hands reduces exposure, the extent of protection is not well understood. Therefore, we set out to determine the degree to which radiation exposure to the surgeon’s hands is decreased with hand-shielding products. Methods: An anthropomorphic model was positioned to simulate a surgeon sitting at a hand table. Thermoluminescent dosimeters were placed on the proximal phalanx of each index finger. The right index finger dosimeter was covered with a standard polyisoprene surgical glove (control arm), whereas the left index finger dosimeter was covered with commercially available hand-shielding products (study arm): lead-free metal-oxide gloves, leaded gloves, and radiation-attenuating cream. Mini fluoroscope position, configuration, and settings were standardized. The model was scanned for 15 continuous minutes in each test run, and each comparative arm was run 3 times. Results: The mean radiation dose absorbed by the control and variable dosimeters across all tests was 44.8 mrem (range, 30-54) and 18.6 mrem (range, 14-26), respectively. Each hand-shielding product resulted in statistically lower radiation exposure than a single polyisoprene surgical glove. Conclusions: The mean radiation exposure to the hands was significantly decreased when protected by radiation-attenuating options. Each product individually resulted in a statistically significant decrease in hand exposure compared with the control. We recommend that in addition to efforts to decrease radiation exposure, surgeons consider routine use of hand-shielding products when using mini c-arm fluoroscopy.

24 consistently right-handed male college students felt sets of four Braille symbols with either the right or the left index finger and identified by touch alone which two of the four symbols in each set were identical. During the task music was played to either the right ear, the left ear, both ears, or neither ear. Significantly fewer errors were made when the music was in the ear contralateral to whichever hand performed the task. The ipsilateral, binaural, and no-music groups did not differ significantly from each other. It is suggested that monaural music to the ear contralateral to the engaged hand led to reduced interhemispheric competition acting on the hemisphere controlling the hand. Such a facilitating effect may be of practical importance in tasks during which one hemisphere receives the bulk of the task-related sensory input and/or processes the final order from the brain to the task-related muscles.
