The Children's Special Health Care Services Advisory Committee is an advisory group that includes stakeholders in the delivery of care for children with special health-care needs. An emphasis has purposely been placed on consumer participation to ensure adequate voice and balance with other provider, legislative, and bureaucratic interests. The Advisory Committee has assumed an aggressive and complete role in reviewing and recommending every aspect of the program. As a result of this active co-ownership, the program has repeatedly survived threats of serious budget cuts and reductions to its base. Agreement between providers and consumers on values, structure, and operational needs has been reached. A win-win approach has been possible, not only in the planning and growth of the program but also in the policy arena, legislatively, and with the administration.

[Correlation between electronystagmographic findings and results of transcranial Doppler ultrasonography of vertebrobasilar arterial system in patients with vertigo].

The purpose of the study was the determination of correlations between the results of electronystagmographic (ENG) investigations and the blood flow velocity in the vertebrobasilar arterial system measured by Doppler ultrasonography in patients with vertigo. The studied material comprised 68 patients (39 women and 29 men) aged 34-68 years (mean 52.4 years). ENG findings included unilateral hyporeflexia in 25 cases (37.7%), bilateral hyporeflexia in 15 (22.0%) and unilateral canal failure in 8 (11.9%). Doppler USG with neck rotation test showed normal flow velocity in 15 cases (22.0%) and pathological velocity in the remaining 53 cases (78.0%). These results showed that bilateral hyporeflexia is found usually in bilateral failure of vertebral arteries and unilateral hyporeflexia and unilateral canal failure were found with unilateral vertebral artery failure on the same side.

Sesquiterpene lactones. Part XIII. Cytotoxic activity of eupatolide and eupatoriopicrin on human and animal malignant cells in tissue culture in vitro.

The activity was determined in tissue culture of KB, HeLa human tumor cells. RK normal animal and EAC-E4 Ehrlich ascites carcinoma cells. Eupatolide (EUP) and eupatoriopicrin (EUPP) show similar cytotoxic activity (ED50 from 0-5 to 1-3 mug/ml), dependent on the cell strain used. In plate test EUP and EUPP give inhibition zones of 18--19 mm. EUPP exerts progressively destructive influence on EAC-E4 cells in the conditions of Miyamura test. The decrease in EUPP activity was noted in aqueous (pH = 9) and acetone solutions.

[The effect of degenerative cervical spine lesions and blood flow velocity in vertebrobasilar system in Doppler measurement].

The purpose of the study was to establish the effect of degenerative lesions of cervical vertebrae on blood flow velocity in the vertebrobasilar system measured by means of Doppler phenomenon using Transpect--TCD device according to generally accepted principles. The study was carried out in 20 healthy controls and 40 individuals with these lesions (aged 16-60 years). It was found that blood flow velocity in this arterial system is highly variable individually. In patients with degenerative changes pathological reduction of this velocity was found in this system which is an unquestionable evidence of the influence of these lesions on blood flow in vertebral arteries.

[The effect of the neck rotation test on auditory evoked brainstem potentials in healthy subjects].

The purpose of the study was to assess the effect of neck rotation test on the pattern of brainstem auditory evoked potentials in healthy subjects. The study was carried out on 40 healthy subjects aged 19-26 years using a Neuromatic 2000 C device of Dantec, by the generally accepted method. The records were taken with the patient in lying position with head in neutral position and during head rotation through 60 degrees to the right and then to the left side. A click stimulus was fed into the tested ear, its frequency was 10 Hz and it was repeated 2000 times. The filters used were 100 Hz-2 kHz. The records obtained during neck rotation showed that the latency times of various waves were slightly prolonged on the side of the rotation (but were still within normal limits), while on the contralateral side they were similar to those in normal position. Moreover, neck rotation to the right or to the left side caused a bilateral slight shortening of the latency time (in absolute values) between waves I-III, at the expense of slight prolongation of this time between waves III-V which was still within the variability range of the normal values.
