    Congenital absence of pain

    No full text
    A 16-yr-old boy had congenital absence of pain sensitivity and no impairment of other sensory modalities. Routine electrophysiologic investigation showed no abnormalities. The threshold and latency of electrically elicited corneal reflex and cortical potentials evoked by tooth pulp stimulation were normal, but suprathreshold electric stimulation of corneal mucrosa and dental pulp, as well as electric stimulation of dorsal roots, did not elicit pain. The total CSF opioid activity was raised. However, naloxone hydrochloride administration failed to reverse the analgesia. The axon reflex to intradermal injection of histamine dihydrochloride was absent. Cutaneous nerve branches showed unspecific changes affecting part of unmyelinated axons. Most of the unmyelinated as well as the myelinated axons were normal. We consider the case an example of congenital indifference to pain

    Skin picking disorder in 97 Italian and Spanish Cri du chat patients

    Skin picking (SP) disorder is characterized by recurrent SP resulting in skin lesions. Several studies estimated its prevalence as approximately 2\u20134 % of the general population. It is also present in a high percentage of patients with intellectual and developmental disabilities, such as Cri du chat (CdC) syndrome, a rare genetic disorder caused by variable size deletions of the short arm of chromosome 5. The aim of this study was to evaluate, in 97 patients with CdC syndrome, the following data: frequency of SP, patient's age at onset, type, and topographic\u2013anatomic distribution of the lesions presented. The results show that 85% of patients confirm a SP disorder, usually concentrated on the hands, fingers, and the face, with onset between 6 and 10 years of age, regardless of patient's sex. Evidence for early appearance of SP behavior, high prevalence in stressful circumstances, and efficacy of distracting actions immediately suggest the possibility that proper parental information about SP behavior and parental education concerning the methods to deal with this problem may result in its efficient reduction already in childhood
