[Protocol of metabolic investigations in hereditary metabolic diseases].

The authors describe a laboratory investigations protocol to be used by pediatricians facing conditions suggestive of inherited metabolic disorders. This protocol includes: 1) an emergency screening to be systematically performed during the acute clinical phase; 2) samplings to be kept frozen for possible secondary specific investigations according to the results of the emergency screening. In addition a perimortem protocol is also presented, to be applied in every lethal situations in which an inherited metabolic disorder is suspected. The equipment required in order for the clinician to properly perform the different investigations is also described.

Human liver pathology in peroxisomal diseases: a review including novel data.

Results from electron microscopic morphometry, enzyme cytochemistry and immunolocalization in liver biopsies are reviewed. Emphasis is put on the following aspects: 1) relationship between peroxisomal size and enzyme concentration; 2) abnormal enlargement of peroxisomes in many congenital disorders with peroxisomal dysfunction; 3) normal localization of matrix enzymes in several patients with peroxisomal dysfunction, with the exception of catalase, which is mainly cytoplasmic; 4) ghost-like peroxisomes in the liver of several syndromes but not in nine cases labelled as Zellweger; 5) discrepancies between liver and cultured fibroblasts; 6) trilamellar, regularly spaced inclusions, large stacks of which are birefringent, indicate a peroxisomal dysfunction; their absence does not exclude it. The same rule holds for lipid in macrophages which is insoluble in acetone and n-hexane (after fixation). The chemical nature of these two storage materials remains unclear; and 7) proliferation of human peroxisomes is frequent in acquired liver diseases and drug toxicity, but is never accompanied by an increase in size, in contrast to the effect of the fibrates and phthalates in rat and mouse. Novel data from seven peroxisomal patients are included.

Human trifunctional protein deficiency: a new disorder of mitochondrial fatty acid beta-oxidation.

In this paper we report the identification of a new disorder of mitochondrial fatty acid beta-oxidation in a patient which presented with clear manifestations of a mitochondrial beta-oxidation disorder. Subsequent studies in fibroblasts revealed an impairment in palmitate beta-oxidation and in addition, a combined deficiency of long-chain enoyl-CoA hydratase, long-chain 3-hydroxyacyl-CoA-dehydrogenase and long-chain 3-oxoacyl-CoA thiolase. The recent identification of a multifunctional, membrane-bound beta-oxidation enzyme protein catalyzing all these three enzyme activities (Carpenter et al. (1992) Biochem. Biophys. Res. Commun. 183, 443-448; Uchida et al. (1992) J. Biol. Chem. 267, 1034-1041) suggested an underlying basis for this peculiar combination of three enzyme deficiencies. We show by means of size-exclusion chromatography that there is, indeed, a deficiency of the multifunctional beta-oxidation enzyme protein in this patient.

[Ciprofloxacin in the treatment of respiratory infections].

The authors evaluate the clinical efficacy and tolerability of the new wide-spectrum fluoroquinolone ciprofloxacin for management of respiratory tract infections. Of the 20 patients enrolled and treated with 500 mg ciprofloxacin tablets twice daily, 17 (85%) were completely cured, and tolerance was excellent in 19 (95%).
