[Heat and vestibular stimulation].

In 1905 Barany analyzed the nystagmus that appears during the irrigation of the ear with cold and hot water, justifying the phenomenon due to convectives currents in the horizontal semicircular canal. This hypothesis has been widely accepted until doubt was casted on it by the experiences carried out in the Skylab. Of the various mechanisms that could be responsible for the vestibular stimulation in the caloric tests, those which entail convection currents or endolymph expansion would need--we think--thermal gradients very superior to those occurring during these tests, that according to our calculations--always pro such hypothesis--seem insufficient.

[Polymorphic reticulosis of the rhinopharynx].

"Malignant centrofacial granulomatosis" is an unusual but devastating spectrum of lymphoproliferative disorders that is now thought to include several entitites, such as polymorphic reticulosis or peripheral T-cell lymphoma. Characteristically there are destructive centrofacial lesions which often produce difficulties for the diagnostic to the clinician and pathologist. The case of a 71-year-old man diagnosed in our Department as polymorphic reticulosis sitting on the rhinopharynx is reported.

[Head-thrust test: its validity as a diagnostic clinical test].

The head-thrust test is presented as an ideal test to investigate the horizontal vestibulo-ocular reflex. We review its theoretical basis, and assess it as a diagnostic test with a 22 patient series. Its specificity accounts for 100% and the sensibility for 54%. Would this test substitute in the future the caloric test?

[Epithelial-myoepithelial carcinoma of smaller salivary gland].

The epithelial-myoepithelial carcinoma of salivary glands is rarely presented and it's considered as an intermediate grade tumor. Usually are located in the parotid gland, however sometimes occur on minor salivary glands. An epithelial-myoepithelial carcinoma sitting on a palatine minor salivary gland of long course is reported.

[Epithelioid amelanotic melanoma of the nose and paranasal sinuses].

Mucous melanomas are rare, representing 1-3% of melanomata and 3% of malignant nasosinusal tumors. The more usual location is the nasal cavity and paranasal sinuses. In early stages occur with a poor and unespecific features, which delays the diagnosis and worsen the prognosis. An amelanotic melanoma case is reported and bibliographic review of these tumors are made.

[The head-thrust test (HTT): physiopathological considerations and its clinical use in daily practice].

The basis of the head-thrust test is that when a head thrust is made in the horizontal plane, the ipsilateral semicircular channel (SCC) shows gaze stabilization because the homolateral SCC is completely inhibited. This test was studied by electronystagmography and the main parameters, the amplitude and latency of the compensatory ocular movements, were analyzed. The sensitivity, specificity, and positive and negative predictive value of this test were estimated in a series of 22 patients. The values were, respectively, 54, 100, 100 and 68%.

[Star-gait measured by craniocorpography: pattenrs, classification, physiopathological considerations and clinical utility].

The results of craniocorpographic recordings in the Babinski-Weil test are discussed, focusing on the star-shaped variant. The variants of star-shaped gait are defined as posterior, centered, advanced, forward, extreme, and lateral. In 22 healthy individuals and 60 patients, star-shaped gait was the most common deviation. Extreme star-shaped gait was the most frequent variant in the healthy subjects and the backward variant was the most frequent in the patient group.
