Nasal challenges with pollen grains represent one of the techniques of provocation. However, the clinical criteria of positivity are not clearly established. Nasal challenges with increasing numbers of orchard-grass pollen grains were performed in 60 patients allergic to grass pollens and 20 normal subjects. Before any challenge, the nose was washed three times with saline and then lactose, and 50, 150, 450, 1350, and 4050 orchard-grass pollen grains were insufflated into the nostrils until a symptom score of 5 was reached. This score was mainly based on major symptoms of allergic rhinitis, for example, rhinorrhea, nasal obstruction, sneezes, and to a lesser extent, on minor symptoms, such as pruritus, conjunctivitis, and pharyngitis. Nasal secretions were obtained after each challenge by lavage. Histamine was titrated by a radioimmunoassay with a monoclonal antibody against acylated histamine. Prostaglandin D2 (PGD2) was assayed with an enzyme immunoassay with a polyclonal antibody against PGD2 methoxamine. None of the normal subjects had a symptom score greater than 2; 55/60 patients had a positive challenge. The release of PGD2 was significantly (p less than 0.001, Kruskal-Wallis test) correlated with a symptom score of 5; 74.5% of patients had a significant release of PGD2 in nasal secretions. In contrast, although 58.2% of patients had a release of histamine in nasal secretions when the challenge was positive, the correlation with symptom scores was not significant. PGD2 in nasal secretions increased 3.7-fold after a positive nasal challenge.(ABSTRACT TRUNCATED AT 250 WORDS)

We report three cases of dengue with cutaneous signs that were observed in three women returning from Asia (and that were confirmed by serology). The exanthem has common characteristics: progressive appearance beginning on thewer limbs, macula-type elementary lesion associated with purpura, evolution in one single upward spread, confluent lesions with intervals of healthy skin, palmoplantar affection, disappearance of the eruption in an average of ten days, association with conjunctivitis in three cases, pharyngitis in two, epistaxis in two and haematuria in one. The lesions spread to the trunk in one patient only and another patient had pruritus. None of the patients showed signs of a state of shock. According to WHO and, despite the existence of haemorrhages and of a purpura, the three cases reported here cannot be considered as being dengue haemorrhagic fever due to the absence of hemoconcentration. The two types of cutaneous signs observed during the fever are described and their physiopathology is discussed.

One hundred and twenty five children (median age 8.71 years) suffering from perennial allergic rhinitis were treated in a randomized, double-blind, parallel group study comparing azelastine nasal spray 0.14 mg/nostril twice daily (0.56 mg/day) and placebo nasal spray. Medication was given for a period of 6 weeks which followed a 2 week placebo washout period in all patients. Subjects were aged between 5 and 12 and were skin prick positive to either house dust mites and/or cat or dog dander. Concomitant anti allergic treatment was not permitted during the study. Severity of rhinitis symptoms was scored daily by the child or his/her parents on a diary card using a visual analogue scale (VAS) for each evaluated symptom: 0, absent-100, could not be worse. Mean weekly scores were calculated. Symptoms evaluated were: sneezing, nasal blockage, nasal itch and rhinorrhea. In addition, at each clinic visit the investigator evaluated symptoms using a verbal score of 0, no symptom-3, severe. Compared to the baseline, for each of the six study weeks, the reduction in the VAS scores for all four symptoms was statistically greater for the azelastine group compared to the placebo group. The investigator's assessment at clinic visits bore out these results. Both azelastine nasal spray and placebo were well tolerated, no serious adverse events were reported. During the treatment phase of the study a total of 36 adverse events were reported by 25 patients (azelastine 10, placebo 15). The most frequently occurring events were pharyngitis (azelastine 5, placebo 3), cough (azelastine 3, placebo 1) and bronchitis (azelastine 1, placebo 3). In conclusion, azelastine has been shown to be effective in the treatment of perennial rhinitis in children aged 5-12 years and to be superior to placebo in the relief of all symptoms assessed, namely sneezing, nasal blockage, nasal itch and rhinorrhea.

The aim of this study is to evaluate the prevalence of dermo-respiratory symptoms from lung-function spirometer values and serum IgE levels in farmers who have been exposed to pesticides in the United Arab Emirates (E.A.U.). The study was a comparison of 98 farmers with 98 non-farmers, the two groups were equivalent in age, sex and selected regions--the town of Al-Ain and in the Emirates of Dubai, Sharjah and Fujairah. Most of the farmers were illiterate or poorly educated (p < 0.0001). Most lived in prefabricated houses (50.5%). Use of chemical substances (70.9%) and a mixture of pesticides by the farmers (60.2%) was very high. The results revealed that the farmers had a very high prevalence of chronic dermo-respiratory symptoms. These differences are statistically significant when compared with the reference group, particularly for the following symptoms: cough (p < 0.003), pharyngitis (p < 0.0003), bronchitis (p < 0.02), asthma (p < 0.008), respiratory insufficiency (p < 0.006), pneumonia (p < 0.003), dyspnea (p < 0.006), nasal catarrh (p < 0.001), sinusitis (p < 0.05), pharyngeal irritation (p < 0.01), nasal irritation (dryness, sneezing and secretions) (p < 0.005), ocular irritation (p < 0.05), cutaneous pruritus (p < 0.002), and contact dermatitis (p < 0.02). The spirometer tests (all parameters together) measured in the farmers were significantly reduced by comparison with the reference group. In conclusion, the authors suggest that a high prevalence of dermo-respiratory symptoms, supported by reduced spirometer tests and high serum IgE, is associated with exposure to pesticides. These results are clearly useful for establishment of work-related reduced exposure in the future.

Alefacept belongs to the new generation of drugs applied in the treatment of psoriasis. It is an immunomodulatory recombinant, fully human lymphocyte function associated antigen-3/immunoglobulin G1 fusion protein (LFA-3-Ig) CD2 antagonist that targets memory-effector T cells by binding CD2 on the T cell surface. It blocks the interactions of leukocyte functional antigen (LFA)-3 with CD2 interaction. This drug is used to treat moderate-to-severe chronic plaque psoriasis and there was conducted a pilot study of psoriatic arthritis. It was observed that Alefacept had reduced peripheral-blood memory effector T-lymphocyte (CD45RO+) counts, cells which are responsible for sustaining the disease. Pharyngitis, dizziness, increased cough, nausea, pruritus, myalgia, chills, injection site inflammation, and accidental injury were recorded. So far, in the conducted trials no generalised immunosuppression or increased risk of infection or malignancy were observed. The possibility of increased risk of infections and malignancies must be considered because of reduced lymphocyte counts.

Primary Epstein-Barr virus (EBV) infection is often asymptomatic before five years of age, whereas it is more likely to be symptomatic in older children, adolescents and young adults. The classic triad of symptoms including fever, pharyngitis and lymphadenopathy is well known, but the spectrum of clinical manifestations associated with EBV infection is large and continues to expand, including increasing atypical presentations. This article presents the case of a five-year-old female in which only a protracted and severe itch, resistant to antihistamines, caught the attention of the girl's parents, thus allowing the diagnosis of EBV. Furthermore, EBV related splenomegaly and mild hepatitis as well as thrombocytopenia had an atypical prolonged course.

Caterpillar dermatitis (lepidopterism) is a disease that is caused by butterflies, moths and their caterpillars. Clinical signs and symptoms vary from itchy skin lesions to conjunctivitis, pharyngitis, malaise and anaphylactic reactions. We present the case of two brothers with typical skin lesions of leptidopterism. The older boy showed skin lesions after playing with caterpillars in the garden, whereas his younger brother was affected without direct contact to the caterpillars but only by playing with his brother. As the mother could show two caterpillars, lepidopterism could easily be diagnosed. Under a local therapy with a medium potent corticosteroid cream and a non-sedating orally administered antihistamine, all skin lesions as well as itching disappeared within 1 week.

The adverse effects profile of levetiracetam in epilepsy is still being fully described. We recently published a Cochrane Review evaluating the effectiveness of levetiracetam, added on to usual care, in treating drug-resistant focal epilepsy. The five most common adverse effects were reported and analysed with no scope for reporting any less common adverse effects than those. Here, we report and analyse the remaining adverse effects (including the five most common). These were (in decreasing order of frequency) somnolence; headache; asthenia; accidental injury; dizziness; infection; pharyngitis; pain; rhinitis; abdominal pain; flu syndrome; vomiting; diarrhoea; convulsion; nausea; increased cough; anorexia; upper respiratory tract infection; hostility; personality disorder; urinary tract infection; nervousness; depression; aggression; back pain; agitation; emotional liability; psychomotor hyperactivity; pyrexia; rash; ECG abnormalities; decreased appetite; nasal congestion; irritability; abnormal behaviour; epistaxis; insomnia; altered mood; anxiety; bloody urine; diplopia; dissociation; memory impairment; pruritis; increased appetite; acne; and stomach discomfort. Only somnolence and infection were significantly associated with levetiracetam. When adverse effects pertaining to infection were combined, these affected 19.7% and 15.1% of participants on levetiracetam and placebo (relative risk 1.16, CI 0.89-1.50, Chi(2) heterogeneity p = 0.13). Somnolence and infection further retained significance in adults while no single adverse effect was significant in children. This review updates the adverse effects profile data on levetiracetam use by empirically reporting its common and uncommon adverse effects and analysing their relative importance statistically using data from a group of trials that possess low Risk of Bias and high Quality of Evidence GRADE scores.
