[Bladder hemangioma. Presentation of a case and review of the literature].

The Authors report a case of hemangioma of the bladder, probable relapse of a similar neoplasia treated with endoscopic diathermy 28 years before, in a 34 year old patient. The clinical presentation, the localization, the subject's age, the therapy and the lesion's histological type recall the main features of this neoplasia. Contrary to all traditional concepts, the diagnosis was made after a biopsy, with no particular problems occurring during the examination. The localization in the bladder dome allowed a good surgical exeresis in a healthy tissue causing a further relapse to be unlikely despite the muscular invasion of the neoplasia.

[Pattern of vestibular reactions and sensory interactions in weightlessness (data of the experiment "Optokinesis")].

This paper presents results of studying spontaneous and evoked optokinetic, opto-oculomotor and vestibulo-oculomotor reactions in microgravity. The examinations were performed during the 7-day Soviet-Indian and 237-day Salyut-7 missions. During an early stage of adaptation to microgravity the following changes occurred: enhanced spontaneous activity of the eyes, including spontaneous nystagmus in one of the crewmembers, decline of the efficiency of saccadic pursuit (disappearance of saccades in the course of pursuit of a moving stimulus, decrease of the saccadic amplitude, emergence of correction microsaccades in response to fixation events), and decrease of the threshold of the optokinetic nystagmus. The compensatory counter-rotation of the eyeballs during head side-to-side movements with open eyes in dark glasses did not disappear but slightly decreased, being slightly accompanied by low-amplitude nystagmus. When rocking the head with open eyes, one of the cosmonauts showed a complete eye destabilization and other cosmonauts displayed high-amplitude nystagmus. In response to head rotation with open eyes they developed clonic nystagmus. Vestibular stimulation in the form of active head movements helped to normalize the pattern of opto-ocular responses.

[Characteristics of optokinetic, opto-oculomotor and vestibulo-oculomotor reactions in weightlessness].

Investigations of spontaneous and evoked optokinetic, optooculomotor, and vestibulooculomotor reactions in microgravity are described. The investigations were performed during the 7-day Soviet-Indian flight and during the 237-day Salyut-7 flight. At an early period of adaptation to microgravity spontaneous oscillations of the eyeballs were enhanced: spontaneous nystagmus (in one of the subjects), lower effectiveness of saccadic pursuit (saccade elimination during the pursuit of a moving target, decrease of saccade amplitude, appearance of corrective microsaccades during fixation turns and pursuit), decline of the optokinetic nystagmus threshold. Compensatory eye counterrotation, when the head moved from side-to-side in the frontal plane with eyes open and dark glasses on, did not disappear but attenuated slightly; it was followed by low amplitude nystagmus. When the head moved with eyes open, one of the crewmembers showed complete eye destabilization while others--high amplitude nystagmic oscillations. When the head turned around with eyes open, clonic nystagmus occurred.
