[Cerebral calcifications: a clue for a diagnostic process in a nonspecific clinical case].

Coeliac disease is a gluten sensitive enteropathy, autoimmune in origin, which has been traditionally regarded as a gastrointestinal disease. Years later it has been reported an extraintestinal affection. A huge number of neurological syndromes of unknown cause had been initially described in association with coeliac disease, with total or partial response to a gluten free-diet. A specific kind of occipital cerebral calcifications in relation to coeliac disease has been also described, and sometimes it means the existence of a syndrome called "Gobby's Syndrome". We show a patient with a mild unknown coeliac disease, a woman who had occipital cerebral calcifications in a TAC cerebral, which was made because of her intractable migraines and that it lead to the diagnosis. The migraine disappeared after a gluten free-diet, like similar cases reported by literature. The fact of existing neurological symptoms associated to coeliac diseases opens a therapeutic window of opportunity because they would respond to a gluten free-diet.

[Stuttering as the only manifestation of a cerebral infarct].

A 53-year-old right-handed man acutely developed stuttering. On his examination there was blocks and repetitions exclusively on first syllables of words in conversational speech, improving in automatic tasks. There was neither aphasia, nor other neurological deficits. An MR imaging of the brain showed a circumscribed cortical infarct on the left precentral circunvolution. Cerebral angiography was consistent with atherosclerotic narrowing of the intracavernous segment of left internal carotid artery. Artery-to-artery embolism was the suggested mechanism for this stroke and the patient was treated with oral anticoagulants for six months. Stuttering improved progressively and the patient became asymptomatic a month after the stroke. Ictal acquired stuttering symptomatic of ischemic stroke without aphasia or other neurological deficit is exceptional. An small infarct on the left motor area as cause of isolated acquired stuttering adds new information about neural circuits involved in this phenomenon.

[The use of FD-6 monoclonal antibody in diagnosing and detecting the carriers of familial amyloidotic polyneuropathy type I].

Familial amyloidotic polyneuropathy type I (FAF-I) is caused by a specific genetic mutation that gives rise to a transthyretin anomaly whose presence in serum constitutes the biochemical marker for this disease. We studied the serum of 7 patients and 16 asymptomatic members of their immediate families using ELISA with FD-6 monoclonal antibody to detect the transthyretin anomaly. Positive results were found for the 7 patients, including the 2 patients whose disease was apparently sporadic, and 12 carriers were detected among the family members. This technique makes sural nerve biopsy unnecessary for establishing a diagnosis in patients whose clinical signs are consistent with FAP-I. Asymptomatic carriers are also detected, facilitating appropriate genetic counseling.

[Peripheral neuropathy in progressive systemic sclerosis].

We report a patient that developed a sensorimotor polyneuropathy more than a year before the appearance of the typical clinical signs of progressive systemic sclerosis. A sural nerve biopsy showed epineural vasculitis with involvement of the basal membrane of the endoneural vessels, without proliferation of the connective tissue.
