[Pourfour du Petit syndrome].

The Pourfour du Petit's syndrome is characterized by the unilateral appearance of mydriasis, lid retraction and exophthalmos. It suggests the existence of a localized oculosympathetic hyperactivity. It tends be to caused by injuries that suppose a stimulus of the sympathetics fibers at level of the proximal portion of the first dorsal root or in the cervical sympathetic chain. We report the clinical case of a young patient who developed a Pourfour du Petit's syndrome secondary to a small condrosarcoma of the proximal portion of the first rib. The observation of this syndrome is exceptional but its knowledge permits, by the great topographic value that possesses, a rapid identification of the causative injury.

[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.

[Benign amaurosis fugax].

In young patients episodes of amaurosis fugax usually correspond to processes not related with atherosclerosis of the extracranial vessels such as migraine, cardiac embolism, vasospasm, vasculitis, oral contraceptives or hematologic disease. In 11% of the cases, however, no cause can be found. These idiopathic cases generally have a benign course and their frequency decreases spontaneously allowing them to be described as benign amaurosis fugax. We describe four cases of amaurosis fugax in which no responsible cause was found despite extensive clinical, laboratory ultrasonographic and angiographic studies. The episodes progressively remitted. In these cases of benign amaurosis fugax the risk of a permanent deficit is exceptional and treatment is not necessary.

[Natural history of a bilateral carotid dissection].

The coexistence of arterial dissection in several cervical vessels is exceptional and is usually an accidental finding detected upon performance of an extensive angiographic examination in patients with unilateral manifestations. The absence of previous clinical manifestations related with asymptomatic vessel dissection impedes the knowledge of the time between the different dissections. The case of a bilateral carotid dissection (CD) is presented in which the clinical course permitted the authors to know the interval between both dissections. The patients initially presented manifestations of right CD and, at 15 days, an ictus due to left CD in which the presence of right unilateral asterixis was of note. The time span between both dissections was established as 12-15 days.
