Pseudolymphoma tattoo-induced.

Tattooing has become more and more popular in today's society. The most common dermatological tattoo complications are represented by hypersensitivity reaction to tattoo pigments like irritant and allergical contact dermatitis, development of lichenoid areas and granulomatous responses, such as sarcoid granulomas or foreign body granulomas. Less frequently patients developing discoid lupus erythematous have been reported.

Electrophysiological study of neurologically asymptomatic HIV1 seropositive patients.

EEGs, brainstem auditory evoked potentials (BAEPs) and auditory event-related potentials (ERPs) were recorded from 33 individuals infected with the human immunodeficiency virus, type 1 (HIV1+ patients: 13 CDC Class II or III; 20 Class IV). All were neurologically asymptomatic, non-demented, and had a past history of intravenous drug abuse. Sixteen age- and sex-matched normals and 10 HIV1- former drug addicts served as controls.

Electrophysiologic study of HIV-1 + patients without signs of peripheral neuropathy.

HIV-1 seropositive patients have a high frequency of nervous system diseases, and asymptomatic abnormalities are frequently detected. We studied 124 neurologically asymptomatic HIV-1 seropositive subjects and 23 normal control subjects by nerve conduction studies. No alterations were detectable in the asymptomatic stages of infection (CDC groups II and III), while subclinical peripheral nervous system (PNS) impairment was detected in symptomatic HIV-1 stages (CDC group IV).

Peripheral and central nervous system anomalies in HIV-1 infection: an electrophysiological study.

This study explored the neurophysiological changes in 87 HIV1+ (20 AIDS, 24 ARC, 24 LAS and 19 AC) patients showing no clinical evidence of neurological impairment. Tracing somatosensory responses by recording SEPs from upper and lower limbs, we found a slowing of both peripheral and central nerve conduction. Peripheral alterations occurred in virtually all patients of the AIDS group.

Neurological involvement in group iv HIV-positive patients. Neurophysiological and clinical data.

Spinal and cortical SEP responses were recorded during tibial and median nerve stimulation in 58 HIV+ subjects (8 IV/C1, 24 IV/C2 & IV/A, 11 III and 15 II), all asymptomatic from a neurological point of view. The electrophysiological features were compared with clinical assessment and serum HIV markers for purposes of prognosis and therapy. In group IV we observed a slowing of conduction along the afferent pathway in the spinal tracts and afferent ways to the cortex.
