A paraffinoma is a type of inflammatory lipogranuloma that develops after the injection of an artificial mineral oil, such as paraffin or silicon, into the foreskin or the subcutaneous tissue of the penis for the purpose of penis enlargement, cosmetics, or prosthesis. The authors experienced a case of macro-paraffinoma associated with sexual dysfunction, voiding dysfunction, and pain caused by ...

We have reviewed 15 patients with infected total knee replacements after removal of the prosthesis, rigorous debridement, antibiotic irrigation, and prolonged systemic antibiotics. Infection was permanently eradicated in all patients; they were left with a functioning limb, on which they could walk with either a caliper (8 patients), a simple splint (3), crutches, or sticks. Three were disappoi...

Today, often ankle’s active prosthesis is used for transtibial amputated people’s walking, because these prostheses have some advantages such as increasing power and decreasing metabolism. In most of active prosthesis in order to create a movement or increase the force at the push-off, electrical actuators are used like a motor. In cases where a higher-power motor is necessary, the capacity, we...

Collagen, a unique connective tissue protein finds extensive application as prosthesis, artificial tissue, drug carrier, cosmetics and leather industry. This work has been undertaken to stabilize collagen using oxazolidine zirconium oxalate crosslinking agents. It found that both imparts thermal stability collagen, exhibits marked rise in the peak temperature when compared native tanned collage...

Due to various reasons, a person who is missing one eye may experience psychological as well excruciating suffering. Enucleation and evisceration surgery are the most often used methods remove sick or injured eye. The patient fitted with bespoke implant into orbital tissues after surgeon removes In order keep socket from looking hollow depressed, this replaces volume. Once has stabilized, prost...

The objective of the project described in this paper is the development of a cybernetic prosthesis, replicating as much as possible the sensory-motor capabilities of the natural hand. The human hand is not only an effective tool but also an ideal instrument to acquire information from the external environment. The development of a truly human-like artificial hand is probably the most widely kno...

We developed and tested a brain-computer interface for control of an artificial speech synthesizer by an individual with near complete paralysis. This neural prosthesis for speech restoration is currently capable of predicting vowel formant frequencies based on neural activity recorded from an intracortical microelectrode implanted in the left hemisphere speech motor cortex. Using instantaneous...

Dentures which included a reservoir for dispensing artificial saliva were constructed for a trial group of patients with oropharyngeal cancer seen in the postirradiation period. The tumors were apparently under control, but the patients were suffering from xerostomia. Details of the design, construction, and use of such a device are presented. The subject of postirradiation xerostomia in the ed...

The paper describes a new method and system, designed for application to upper extremity prosthesis. Artificial limb with our new system is robot arm controlled by EMG signals and monitored and corrected by set of ultrasonic sensors. The control system used to control robotic arms measured EMG signals from muscles and the signal from the ultrasonic sensors detect obstacles in the robot's motion...

The electrical stimulation of the optic nerve is investigated, as an approach to the development of a microsystems-based visual prosthesis. Non-linear prediction models, i.e. artificial neural networks, for phosphene localisation are used and show promising results. The prediction error is reduced up to 20% in comparison with linear statistical models and the error standard deviation is restrai...
