[The morphological and morphometric study of the segment of the labyrinth of the fallopian canal].

The study of the Fallopian canal with bone specimens can offer an exact and valuable information on the morphology of this duct and its close relations with neighbouring structures. The aim of this paper is to give an actualized compilation of the updated know findings, regarding the morphology and the morphometry of the first segment of the Fallopian canal. The study is based on 92 human temporal bones coming from skulls of adult subjects of both sexes. After a careful drilling work the whole length of the canal, that of the I.E.C. and the corresponding to the labyrinthine segment as well, were exposed and measured. The results allowed the AA. the macroscopical checking of the inversed ratio between the length and the calibre of the investigated canals. The labyrinthine portion of the facial canal is more narrow at its beginning (at the bottom of the I.E.C.) becoming broader as the duct approaches the first knee (geniculated ganglion) of the nerve.

Dexamethasone perfusion of the labyrinth plus intravenous dexamethasone for Ménière's disease.

Recent clinical and laboratory evidence indicates that Meniere's disease is an immune-mediated disease. Dexamethasone perfusion of the inner ear through the round window plus intravenous dexamethasone often will stop the dizzy spells, reduce the fullness and low-frequency tinnitus, and sometimes improve the hearing in patients with Meniere's disease. The dexamethasone must act mostly on the endolymphatic sac and, to a lesser extent, on the stria vascularis and spiral ligament, the known targets of immune response in the inner ear, to reduce the endolymphatic hydrops and restore the fluid dynamics of the endolymph. Despite the good results with streptomycin perfusion, the number of patients with further hearing loss is large, so dexamethasone perfusion with intravenous dexamethasone should be tried first. The initial response to dexamethasone perfusion plus intravenous dexamethasone has been very good, with very little risk of further hearing loss, and it holds great promise for the future.

The labyrinth of IDEA: school decisions on referred students with subaverage general intelligence.

A sample of 150 children referred to Student Study Teams was assessed with a psychometric battery. Behavioral and academic ratings were obtained from teachers. Forty-three children scored at or below 75 on the WISC-III. We examined schools' subsequent classification decisions to ascertain how schools dealt with low-IQ students with academic and behavioral problems. Schools reached decisions regarding 35 of the children: Only 6 were classified as having mental retardation, and 18, as having learning disabilities. Findings were discussed in terms of (a) decline in identification rates of mild mental retardation and (b) the extent to which school decisions adhere to the research criteria.

[Physiologic approach to promoting circulation in acute labyrinth ischemia. A new treatment concept].

BACKGROUND: One of the main factors of sudden hearing impairment, acute vestibular disturbance, and acute tinnitus is generally thought to be an acute labyrinthine ischemia of varying degrees. However, the scientific basis for this assumption has not yet been proven, and there is a great variety of treatment modalities. Recent circulation research and fundamental physiological considerations led to the development of a new concept of treatment of these diseases. METHODS: In order to enhance the labyrinthine blood circulation, physiological and physical methods were tested in 42 patients, especially with regard to patient compliance and in addition to conventional therapy. The methods tested included active circulation training. Finnish bath observing certain precautions, sequentially increased temperature bathing, massage, and fango therapy of the neck. RESULTS: The compliance of the patients to the new concept was good, in some cases even enthusiastic, either to the "total body" methods or to the local neck treatment. CONCLUSION: The principle of active and/ or passive stimulation of blood circulation in acute labyrinthine ischemia has been well accepted by all patients. A study including functional results is in preparation.

[Effect of psychostimulants on the relearning by rats of the avoidance direction in a U-shaped labyrinth].

The capacity of rats to relearning the direction of the avoidance in a U-shaped maxe was determined. Four traning sessions--each time in a new direction (to the right, or to the left) of running were conducted. D, 1-amphetamine given in low and medium doses (0.5 and 2 mg/kg) shortened the latent response periods and failed to influence the relearning of the animals. A high dose of the drug (5 mg/kg) led to reduction of the latency of the responses, but at the same time inhibited the reconstruction of the avoidance habit; this distinctly correlated with the intensification of space preference. Caffine (25 and 50 mg/kg) failed to influence the relearning of rats.

[Laser destruction of the labyrinth in Meniere's disease: rationale and results].

The authors suggest that Meniere's disease may arise as a psychovegetative syndrome with impairment of labyrinthine homeostasis. It is thought valid to distruct the cupular receptor of the horizontal bony semicircular canal by means of impulse neodymium laser radiation brought to the ampullare bone wall via quartz light guide. Short- and long-term effects of such laser treatment are available. This technique of laser destruction is symptomatic, aimed at relief of severe episodes of vertigo.
