Topesthesia, the recognition of tactile stimulation location on the skin, can be severely affected by neurological injuries, such as stroke. Despite topesthesia being crucial for manipulating objects and interacting with the environment during activities of daily living, deficits cannot be quantitatively captured with current clinical assessments and are, as a consequence, not well-understood. The present work describes a novel automated assessment tool for tactile mislocalization in neurological patients with somatosensory deficits. We present two cases of ischemic stroke patients, describe their tactile localization deficits with the automated assessment, and compare the results to a standard manual clinical assessment. Using the automated assessment tool, it was possible to identify, locate, precisely quantify, and depict the patients' deficits in topesthesia. In comparison, the clinical assessment was not sensitive enough and some deficits would remain undetected due to ceiling effects. In addition, an MRI structural analysis of the lesion supported the existence of somatosensory deficits. This novel and quantitative assessment may not only help to raise awareness of the implications of deficits in topesthesia, but would also allow monitoring recovery throughout the rehabilitation process, informing treatment design, and objectively evaluating treatment efficacy.

A 58-year-old female exhibited the onset of symmetrical sensory abnormalities of the face and extremities. The neurological examination revealed normal muscle strength with abated or absent tendon reflexes. The patient experienced symmetrical glove- and stocking-type pinprick sensations in the distal extremities and a loss of temperature sensation, but had normal proprioception and vibration senses and joint topesthesia. The lumbar puncture showed protein cell separation at the fifth week after the onset of symptoms. At the same time-point, the electrophysiological examination showed demyelination changes involving the trigeminal nerve and the somatic motor nerve. Needle electromyography revealed normal results. The clinical symptoms ceased progression at the fourth week after symptom onset, and began to improve from the sixth. This case was considered to be sensory Guillain-Barré syndrome, which was characterized by its cranial nerve involvement.

The present study was so designed to evaluate the change of topesthesia based on the degree of resorption of deciduous teeth and the grade of root formation of permanent teeth. A total 12315 teeth (6140 deciduous teeth and 6175 permanent teeth) from 311 boys and 364 girls, whose ages ranged from 3.9 to 17.2 years (average 8.3 years) were examined. After taking dental X-rays, 20 g of pressure was applied on the axially direction on each tooth, and then the child was requested with his index finger to identify which tooth was perceived to be pressed. A specially designed tooth pressing device was used. For reference, the measurement of the root surface was made on an extracted tooth using a digital image analyzer (MAGISCAN-IIA). The followings were the results obtained in the present study. 1) The topesthesia of the teeth was found to be more accurate in mesially located teeth than in distally located teeth. Some children falsely indicated the mesially located teeth. 2) The topesthesia of deciduous teeth was increased more as the resorption of the teeth was progressed. 3) The topesthesia of the permanent teeth decreased as the root formation developed. 4) Negative correlation was noticed between the topesthesia and amounts of the root surface remaining. (Correlation coefficient of upper jaw -0.94, lower jaw -0.89).

Due to the loss of topesthesia and to the impairment of the vasomotorium in the paralyzed area, patients suffering from tetraplegia have a high risk from pressure sores. Bed sores respond successfully to therapy if, on observing the relevant basic nursing procedure--requiring in particular that the damaged areas of skin be consistently relieved from pressure by means of special positioning of the patient--the sores are subjected to intensive cleansing via surgical and/or enzymatic débridement, and are conditioned with the synthetic skin substitute Epigard. This is achieved as a result of therapeutic procedure followed in a series of methodical steps. Specific treatment with antibiotics before conditioning the wounds supplements these measures and facilitates the spontaneous healing of the lesions or, in the case of larger bed sores, the optimal preparation of the wound bed prior to skin grafting and plastic surgery.
