[Q]: Abstract: The chronic effects of dietary protein on renal structure and function were studied in rats with normal and reduced renal mass. Control rats with two kidneys were compared with unilaterally nephrectomized rats, and with one and one-third nephrectomized rats obtained by unilateral nephrectomy and infarction of one-third of the remaining kidney. Rats at each level of renal mass were maintained on chow containing either 6% or 40% protein content. Separate cohorts of rats were studied four and eight months after ablation and institution of these dietary regimens. At both time intervals and at all levels of renal mass, rats fed the high protein diet had higher average values for GFR than comparable animals fed the low protein chow. Within each of the dietary regimens the animals with loss of renal mass developed greater prevalences of sclerotic glomeruli by eight months. Furthermore, at each level of initial renal mass, rats eating the high protein diet had a greater prevalence of sclerotic glomeruli than those on the low protein diet. Similarly, rats on the high protein diet had greater rates of protein excretion than those on the low protein diet at each degree of ablation. The prevalence of sclerosed glomeruli increased between four and eight months in each group. Thus, the extent of renal injury as manifested by proteinuria and glomerular sclerosis was directly related to the degree of initial loss of renal mass, and dietary protein restriction retarded these manifestations of injury across a wide range of initial renal mass.(ABSTRACT TRUNCATED AT 250 WORDS)

[Q]: Abstract: Hemoperfusion through Amberlite XAD-4 resin column has been shown to effectively remove sedative-hypnotics, analgesics and other drugs causing acute intoxication. There is no appreciable clinical toxicity and dramatic shortening of coma time and possible decrease in mortality may be achieved. Thrombocytopenia and clotting may be diminished by pre-perfusion coating with 2.5% albumin. Albumin coating may facilitate the repeated use of hemoperfusion without any complications. More recently, resin hemoperfusion has been used for procainamide, N-acetylprocainamide and theophylline intoxication achieving exceptionally high clearance rates.

[Q]: Abstract: We examined the results of the Northwest Regional Screening Program (NWRSP) over its first 10 years to determine whether the detection of hypopituitary hypothyroidism is a justified advantage of the primary thyroxine (T4)-supplemental thyroid-stimulating hormone (TSH) screening strategy, and to determine whether all such infants will be detected by this screening approach. Between May 1975 and May 1985, the NWRSP screened 850,431 infants, detecting 192 infants with primary hypothyroidism (1:4429) and eight with hypopituitary hypothyroidism (1:106,304). In 11 additional infants, TSH deficiency, not detected by the screening program, was diagnosed on recognition of clinical features over the same period. Thyroid hormone treatment was begun in seven of the 11 infants prior to obtaining the screening sample results because of clinical symptoms of hypopituitarism, including hypoglycemia, persistent jaundice, microgenitalia, diabetes insipidus, midface hypoplasia, cleft lip or palate, or abnormalities of vision. The other four infants were not detected despite clinical features of hypopituitarism (in retrospect) and low serum T4 with TSH concentration below assay sensitivity on at least one screening sample. The most accurate assessment of total cases comes from Oregon, where all cases of congenital hypopituitarism are referred to our center; we estimate a frequency of 1:29,000. In our experience, a combination of newborn T4-supplemental TSH screening measurements and recognition of clinical features of hypopituitarism is the optimal strategy for detecting infants with congenital hypopituitary hypothyroidism.
