Is the EEG cyclic alternating pattern a true autonomous entity? Analytic study in a case of post-traumatic coma with good prognosis.

The cyclic alternating pattern (CAP) characterizes stage-II coma according to Fischgold and Mathis. Its evolution and prognostic value are still uncertain. An analytic investigation of CAP and its components (phase A of greater arousal and phase B of lesser arousal) was conducted on a patient with post-traumatic coma who completely recovered. The relationships between this type of pattern and the stages of physiologic sleep were investigated during four prolonged night recordings taken at regular intervals. The evolution of CAP in post-traumatic coma is compared with the development of CAP observed in Creutzfeldt-Jakob disease. The hypothesis is suggested that CAP may be related to other cyclic phenomena, especially the Lundberg B-type CSF pressure waves. According to this assumption, in a coma with CAP, mechanisms for the organization of arousal, which are not known but persist up to the threshold of death, could still be acting. In sleep these same mechanisms are supposed to be integrated with others, more sophisticated and less resistant to pathogenic injuries.

Facial myokymia in the course of a pontine tumor.

A patient with facial myokymia, suffering from an infiltrating grade II astrocytoma originating within the pons with vegetations invading the cerebellopontine angle, was studied clinically and electromyographically from 1973 to 1979. The myokymias started in the muscles of the right side of the face and later spread to the left side. The latter point is worth noting because the myokymias of the left side were detectable by EMG but not by inspection. They preceded clinical and instrumental evidence of a contralateral spread of tumoral damage to the brainstem. From the physiopathogenetic angle they point up the importance of a mechanism of hyperexcitability and release of the facial motoneuronal pool. The results of the EMG study suggest that the persistence of myokymia, its association with an ingravescent neurogenic impairment of the facial musculature and its polymorphism in the course of pontine tumors are more reliable features than their discontinuity and rhythmicity.

Transient hemiballismus and subclavian steal syndrome. Case report.

Transient hemiballismus was observed in a 74-year-old man, displaying subclavian steal syndrome. Such a correlation has not been previously reported in the literature. In this case, transient hemiballismus seemed to depend on hemodynamic factors, but other mechanisms possibly explaining early recovery of the hyperkinesias are discussed. In particular, stress is laid upon the role of preexisting pathological changes of the central nervous system (diffuse cerebral atrophy) associated to the "releasing" lesion.

Multiple disseminated pyogenic granuloma.

A 15-month-old baby girl with extensive skin burns developed within the burned areas multiple lesions with the clinical and histological characteristics of granuloma pyogenicum. These lesions seem to differ from those reported by others as pyogenic granuloma with multiple satellites.

Squamous cell carcinoma of the nail bed.

A case is presented of squamous cell carcinoma developed from carcinoma in situ of the nail bed of the first finger in a 79-year-old patient. Stress is laid upon the importance of the differential diagnosis. Surgery is considered the treatment of choice for this uncommon condition.

[Scleroatrophying and degenerative keratodermic genodermatosis of the extremities].

A case of a picture described by Huriez et al. under the title of scleatrophying and keratodermic genodermatosis of the limbs usually degenerative is presented. In the genealogic study it was observed that seven out of the sixteen members that belonged to this primary family group were affected or probably affected and it is stressed that one of them died from metastasis of spinocellular epithelioma.

[Keratodermic genodermatosis with hydrocystomas, miliary cysts, xanthelasmas, nail and dental dystrophies, and basal cell epitheliomas].

Two cases of a condition including palms and soles keratoderma, ectodermal dysplasias and basal cell epitheliomas are reported by the authors, with clinical, genetical and pathological data. The condition is called Keratodermal Genodermatose with hydrocystomas, milium cysts, xanthelasma, dental and nail dysplasias and basal cell epitheliomata (Borda's syndrome).
