[Cerebral adrenomyeloneuropathy as a late type of adrenoleukodystrophy: case report].

Adrenoleukodystrophy (ALD) is a hereditary disease related to abnormalities in the structure and function of peroxisomes. The nature of disorder arises from defective process of beta-oxidation of very-long-chain fatty acids and their accumulation in various organs. ALD may present as a few phenotypes urologic symptomatology of which depends on proportions of the brain, spinal cord and peripheral nerves affection. Below, we present a case (and its family) of a cerebral type of adrenomyeloneuropathy--a rare form of adrenoleukodystrophy, and discuss its clinical manifestation as well as biochemical, hormonal, electrophysiological, neuropsychological and magnetic resonance imaging (MRI) diagnostics.

Aspirin-induced urticaria--a clinical study.

This paper describes the clinical characteristics of patients with aspirin-induced urticaria. The group of 71 patients (49 women and 22 men), with a mean duration of symptoms of 32.5 years, underwent allergological, laryngological and histamine dihydrochloride inhalation tests. Nasal polyps were found in 2 patients (2.8%), atopic disease in 23 (32.3%) and at least one feature of atopy in 37 (51.9%). Forty-nine patients (69%) suffered from urticaria which was not associated with aspirin. In 22 patients, urticaria developed solely due to aspirin. Urticaria not associated with aspirin has been present from 2 weeks to 30 years before the onset of sensitivity to aspirin. The authors conclude that aspirin-induced urticaria results from two different concomitant phenomena, i.e. sensitivity to aspirin and urticaria not associated with ingestion of the drug.

Urticaria/angioedema-type sensitivity to aspirin and other nonsteroidal anti-inflammatory drugs. Diagnostic value of anamnesis and challenge test with acetylsalicylic acid.

The aim of this study was to determine the value of challenge tests with acetylsalicylic acid in the diagnosis of ASA-induced urticaria. The study was performed in 71 patients with suspected urticaria/angioedema-type sensitivity to ASA. Anamnesis confirmed sensitivity in 67 patients (94.4%) and showed that sensitive patients usually suffered from extensive urticaria (37 patients, i.e 55.5%) after ingestion of ASA. Eight patients (12%) reacted with loss of consciousness and 4 (6.0%) with edema of the larynx. Oral challenge test with acetylsalicylic acid was performed in 53 patients, in 49 (92.4%) of whom it was positive. Threshold doses of acetylsalicylic acid ranged from 40 to 300 mg. In 11 patients, the test was repeated and in 8 it was performed 3 times. It was observed that both the threshold acetylsalicylic acid doses and the time of appearance of sensitivity symptoms were variable. All ASA-sensitive patients reacted to indomethacin in a similar manner as to ASA. Paracetamol, on the other hand, was well tolerated by all 25 evaluated patients with urticaria/angioedema-type sensitivity to ASA.

Sensitivity to aspirin--methods of detection of sensitivity and inducing tolerance state to aspirin.

The paper deals with various methods of detection of bronchoconstrictor and urticaria/angioedema types of sensitivity to aspirin and other nonsteroidal anti-inflammatory drugs. The authors consider that anamnesis plays the major part in detection of sensitivity to these drugs. Oral challenge tests should be applied only with the use of acetylsalicylic acid administered at small, increasing doses at intervals not shorter than 24 h. Tolerance to aspirin is elicited using aspirin at 24 hour intervals, beginning with a threshold dose. The authors prefer, however, their own method where a subthreshold dose is the initial one. The protective role of sodium salicylate against aspirin-induced bronchoconstriction is also discussed.

[Aspirin tolerance in individuals with aspirin-induced urticaria-edematous lesions].

The study involved 22 individuals with aspirin-produced urticaria-edematous skin lesions. Hypersensitivity to aspirin was established with anamnesis showing such lesions on aspirin intake and oral test with aspirin. Threshold, provocative dose of aspirin was determined in all patients at the beginning of the study. Moreover, threshold provocative indomethacin dose was additionally determined in 12 patients. Tolerance to aspirin was produced by the oral administration of aspirin in increasing doses upto total dose 600 mg at a 24-hour intervals. Twelve patients were given 25 mg of indomethacin after 24 hours, and 50 mg of this drug after 48 hours. The patients tolerated indomethacin well during aspirin tolerance stage. The authors suggest that both urticaria-edematous and bronchial type of aspirin hypersensitivity are of the same pathogenetic origin.

Serum neutrophil chemotactic activity (NCA) during aspirin-induced bronchoconstriction.

In order to determine mast cell involvement in aspirin-induced bronchoconstriction, 16 aspirin-sensitive asthmatics and 18 control patients were studied for serum neutrophil chemotactic activity, using Nelsons method, before and after oral aspirin administration. A significant increase in NCA was observed in 6 aspirin-sensitive asthmatics during aspirin bronchoconstriction. In two persons the increase was lower. In the remaining 8 persons, no increase in NCA was observed during aspirin bronchoconstriction. None of the control patients exhibited an increase in NCA. The authors assume that, in some of the patients with aspirin-induced bronchoconstriction mast cells are really involved.
