. Trichophyton gypseuni Bodin 1902 or any ot its many variants has not been recorded in India as yet. It is the cause of the small-spored ectothrix trichophytosis in man. Being of animal origin it produces more inflammatory reactions than other ringworm fungi. In children.?It causes the ringworm of the scalp (Tinea capitis) often producing the condition called the 1 kerion ' in which the affect...

Somatic sensation comprises four main modalities, each relaying tactile, thermal, painful, or pruritic (itch) information to the central nervous system. These input channels can be further classified as subserving a sensory function of spatial and temporal localization, discrimination, and provision of essential information for controlling and guiding exploratory tactile behaviours, and an affe...

It has been known for some time that populations of cutaneous and muscle afferents can provide short-latency facilitation of motoneuron pools. Recently, it has been shown that the input from individual low-threshold mechanoreceptors in the glabrous skin of the hand can modulate ongoing activity in muscles acting on the fingers via spinally mediated pathways. We have extended this work to examin...

Tactile corpuscle-like bodies (TCLBs) are specialized mechanoreceptors found in the dermal papilla of glabrous skin. They normally not gastrointestinal (GI) mucosa. There has been an increase incidental detection GI mucosa due to widespread use colonoscopy procedures. However, TCLB's clinical implications tract remain unknown. We present a case 74-year-old man who was noted have TCLBs rectosigm...

The successful treatment of thirteen cases of herpes simplex ofthe skin with 5-iodo-2'-deoxyuridine (5IDU) was reported by Hall-Smith, Corrigan, and Gilkes (1962), and a further series of 22 cases by Jackson (1963). The effects of 5IDU in 43 cases of herpetic keratitis in rabbits compared with an unspecified number of controls have been reported favourably by Kaufman, Nesburn, and Malony, (1962...

Active, self-touch and the passive touch from an external source engage comparable afferent mechanoreceptors on the touched skin site. However, touch directed to glabrous skin compared to hairy skin will activate different types of afferent mechanoreceptors. Despite perceptual similarities between touch to different body sites, it is likely that the touch information is processed differently. I...

The capacities of humans and monkeys to discriminate between the frequencies of mechanical sinusoids delivered to the glabrous skin of the hand have been measured in psychophysical experiments. The 2 primates have similar capacities; they make discriminations with Weber fractions that change little over the frequency range from 20 to 200 Hz. The discriminatory capacities are similar whether sti...

We show that the affective experience of touch and the sight of touch can be modulated by cognition, and investigate in an fMRI study where top-down cognitive modulations of bottom-up somatosensory and visual processing of touch and its affective value occur in the human brain. The cognitive modulation was produced by word labels, 'Rich moisturizing cream' or 'Basic cream', while cream was bein...

The glabrous skin of the monkey's hand was stimulated with a waveform that indented the skin at a rate of 0.4 mm/sec, held the skin steadily or nearly steadily indented for 12 sec or longer, and then retracted back to the starting position. Recordings were made of activity in single afferent fibers in response to these stimuli. The average discharge frequency of 21 slowly adapting mechanorecept...

1. Single unit impulses were recorded with percutaneously inserted tungsten needle electrodes from the median nerve in conscious human subjects. 2. A sample of 334 low threshold mechanoreceptive units innervating the glabrous skin area of the hand were studied. In accordance with earlier investigations, the units were separated into four groups on the basis of their adaptation and receptive fie...
