Abstract: Percutaneous absorption of hydrocortisone was studied in 18 children (aged from 6 weeks to 14 1/2 years) with atopic or seborrhoeic dermatitis, by measuring their serum cortisol before and after application of 1% hydrocortisone cream. Endogenous secretion of cortisol was suppressed with dexamethasone. A 24 h absorption test was performed on nine children. In six, percutaneous absorption was detected. The highest serum cortisol level was reached within the first 6 h. A 4 h absorption test was developed on the basis of the 24 h test. This short absorption test was performed on nine children, and in eight of them absorption of hydrocortisone was detected. The rise of serum cortisol ranged from 98 to 2669 nmol/l. The 2 h ACTH test was performed to evaluate the effect of previous treatment with topical glucocorticoids. Suppressed adrenocortical function was found in five of 13 children, and was associated significantly with high post-application serum cortisol levels. This occurred more often in infants with a severe skin disorder than in older children or in those with mild or moderate skin disease.
Which is the apt title for the abstract? option1: Effect of percutaneous absorption of hydrocortisone on adrenocortical responsiveness in infants with severe skin disease. option2: Technetium antimony sulfur colloid scintiscan in selective lymph node dissection for malignant melanoma.
answer:
Effect of percutaneous absorption of hydrocortisone on adrenocortical responsiveness in infants with severe skin disease.

Abstract: When dog lung lobes were perfused at constant arterial inflow rate, occlusion of the venous outflow (VO) produced a rapid jump in venous pressure (Pv) followed by a slower rise in both arterial pressure (Pa) and Pv. During the slow rise Pa(t) and Pv(t) tended to converge and become concave upward as the volume of blood in the lungs increased. We compared the dynamic vascular volume vs. pressure curves obtained after VO with the static volume vs. pressure curves obtained by dye dilution. The slope of the static curve (the static compliance, Cst) was always larger than the slope of the dynamic curve (the dynamic compliance, Cdyn). In addition, the Cdyn decreased with increasing blood flow rate. When venous occlusion (VO) was followed after a short time interval by arterial occlusion (AO) such that the lobe was isovolumic, both Pa and Pv fell with time to a level that was below either pressure at the instant of AO. In an attempt to explain these observations a compartmental model was constructed in which the hemodynamic resistance and vascular compliance were volume dependent and the vessel walls were viscoelastic. These features of the model could account for the convergence and upward concavity of the Pa and Pv curves after VO and the pressure relaxation in the isovolumic state after AO, respectively. According to the model analysis, the difference between Cst and Cdyn and the flow dependence of Cdyn are due to wall viscosity and volume dependence of compliance, respectively. Model analysis also suggested ways of evaluating changes in the viscoelasticity of the lobar vascular bed. Hypoxic vasoconstriction that increased total vascular resistance also decreased Cst and Cdyn and appeared to increase the vessel wall viscosity.

answer:
Pulmonary vascular compliance and viscoelasticity.

Abstract: Twenty-two patients with evidence of systemic vasculitis and peripheral neuropathy were clinically and electrophysiologically investigated in a retrospective study. Ten had a polyarteritis nodosa, 6 a probable polyarteritis nodosa, and 6 a Churg-Strauss syndrome. Nine patients presented clinically with mononeuropathy or mononeuropathy multiplex considered typical of ischemic involvement of peripheral nerve; nine had more diffuse neuropathy, two of them a symmetric polyneuropathy. EMG examination revealed more diffuse neuropathy than clinically predicted. Findings were of acute or subacute axonal neuropathy.
Which is the apt title for the abstract? option1: Peripheral neuropathy in systemic vasculitis: clinical and electrophysiologic study of 22 patients. option2: Gram-negative bacillary meningitis in the adult: review of 39 cases.
answer:
