Classic markers detect the majority of cases of fragrance contact allergy. We recommend incorporating FM II in the Spanish baseline series, as in the European baseline series, and using a specific fragrance series to study patients allergic to a fragrance marker.

Varicella-zoster virus (VZV) pneumonia is one of the most serious complications of this infection in adults. The objective of this study was to analyze the epidemiological and clinical characteristics in a large sample of patients with VZV pneumonia. This was a 10-y retrospective, descriptive, observational study. We studied 46 patients with VZV pneumonia, 21 men and 25 women, with a mean age 36 +/-11 y. A contact with an index case was observed in 57%, 76 were active smokers, 6.5% consumed drugs and 2 women were pregnant. The symptoms were: fever (83%), cough (83%), dyspnoea (63%), pleuritic pain (70%), and haemoptysis (6%) and started 3-5 days after the onset of blisters, except in 11% in whom respiratory symptoms appeared first. Arterial blood gases showed a mean PO(2)/FiO(2) of 308 +/-101 and 30 patients had a PO(2) of <55 mmHg--11 of these (4%) were admitted to the ICU, 8 required mechanical ventilation. Comparison of patients in the ICU with those on the general ward showed differences in the duration of fever (6.1 +/- 4.2 vs 3.2 +/- 1.1 days, p <0.001), mean stay (16.8+/-9.3 vs 7.2+/-2.4 days, p <0.001) and complications such as acute renal failure (p = 0.01) and acute respiratory failure (p < 0.001). Despite the severity of disease, no patient died. Once diagnosed, 98% were treated with acyclovir, combined with steroids in 6 and with antibiotics in 3 complicated with bacterial pneumonia. The prevalence for the period was 0.33 cases/100,000 inhabitants/y. In conclusion, VZV pneumonia has a severe course and accounts for a high percentage of admissions to the intensive care unit. The absence of mortality may be related to early treatment with acyclovir. Smoking was a risk factor for VZV pneumonia.

Bullous congenital ichthyosiform erythroderma is an unusual type of inherited ichthyosis by mutations in the genes that encode K1 and K10. We report the case of a girl with typical clinical and histopathologic findings of bullous congenital ichthyosiform erythroderma, who was found to have a new mutation in KRT10 gene, Glu445Lys at position 445, affecting the 2B region of the KRT10 protein, the end of the rod domain, where many other keratin mutations associated with hereditary skin disease have been reported. This new mutation contributes to add to the catalog of bullous congenital ichthyosiform erythroderma mutations known.
