[Isolated ACTH deficiency and transient GH deficiency. Presentation of a case].

In a 46 year old man, who arrived at our observation suffering for three months from considerable increasing weakness and progressive impairment of libido, we documented a condition of secondary hypocorticism due to an isolated ACTH deficiency associated with a reduced somatotropin reserve, the last improved after treatment with corticosteroids. We found low serum levels of ACTH and cortisol, good response of adrenal glands to corticotropin depot, normalization of the clinical board during glucocorticoid replacement. Stimulating test with CRH (corticotropin releasing hormone) did not cause a response in ACTH, suggesting the presence of primitive damage of the hypophyseal corticotroph cells.

[Tannin and gallic acid as marker of exposure to hardwood dust].

The total tannin concentration was determined, using two different SPF methods, in 35 dust powdered wood species, both hard and softwood. Using direct reading-method (280 nm) the concentration varied from 2485 mg/g for Swedish pine to 35,843 mg/g for European oak (quercus robur, hardwood). The data obtained with the second method (Folin-Chocalteau) were well correlated (y = 0.9885x + 4.3373; r = 0.84; n=35) with the data obtained with the first method. The measured concentrations are usually higher in hardwood than softwood tested. Finally, a simple HPLC-DAD method was tested for gallic acid (GA), recently proposed as a marker for oak dust.
