Abstract
Methotrexate has been used as an anti-inflammatory agent in chronic asthma. We evaluated the action of methotrexate in eight corticodependent severely asthmatic children (more than 10 mg of prednisone per day for at least one year). The patients (3 males and 5 females; aged 8 to 14 years) received a single weekly dose of 0.6 mg/kg methotrexate (maximum 25 mg) and folic acid (15 mg/day for 5 days in the week). The children were examined and had their pulmonary function test evaluated weekly. As the study progressed, the dose of prednisone was reduced and maintained till the next evaluation if the patient's symptoms were under control. After the 3rd month of treatment, we observed a significant reduction in the dose of prednisone and maintenance of the spirometric parameters. At the end of the trial, in 4 patients it was possible to reduce the basal prednisone dose 56% or more. In the remaining 4, one did not show any benefit and in the other 3, it was possible to obtain an average reduction of 40% of the basal prednisone dose. The total mean reduction was 55.9%. This oral corticoid reduction was not associated with clinical or pulmonary function deterioration, except in one patient. The patients were submitted to white blood cell count, hepatic transaminases, urine tests and other determinations at least once a month. There were no changes in biochemical tests. The side-effects were nausea, vomiting and abdominal pain. In conclusion, methotrexate given to severely corticodependent asthmatic children permitted a reduction in the daily intake of prednisone, reducing the severe side-effects of chronic corticotherapy.

Abstract
In order to study placental transfer of IgG subclasses, paired blood samples were collected from mothers and umbilical cord of preterm (N = 69) and full-term (N = 68) newborns. The full-term group was further divided into 3 subgroups: appropriate for gestational age (AGA, N = 43), large for gestational age (LGA, N = 13) and small for gestational age (SGA, N = 12), according to birth weight. IgG subclasses (IgG1, IgG2, IgG3 and IgG4) were measured by the single radial immunodiffusion technique using monoclonal antibodies. IgG1 and IgG3 newborn subclass concentrations (10.17 and 0.57 g/l, respectively) increased with increasing gestational age and reached maternal levels (IgG1 = 8.86; IgG3 = 0.67 g/l) during the 37th week of pregnancy. Low levels of these subclasses were found in premature newborns. IgG2 from newborns were always lower than maternal levels (P < 0.05). LGA and SGA newborns had equivalent levels of IgG1 and IgG2 compared with AGA. SGA newborns had higher levels of IgG3 and lower levels of IgG4 than LGA and AGA newborns.

Abstract
Patients during a mild to moderate acute attack of asthma (FEV1: 50 - 80% of predicted) were treated with Salmeterol MDI - 50mcg or Rotadisk - 50mcg or Salbutamol (MDI -200mcg). The children were followed by Spirometry, measuring FEV1 (basal) and after treatment: at 30 minutes, 60 minutes and thereafter every 60 minutes until 780 minutes, if the patients maintained the FEV1 above 80% of the predicted value and/or an increment of 20% in the VEF1 basal value. The Salmeterol group showed a significant bronchodilation at 60 minutes which was maintained in half of the patients up to 9 hours. This was not observed in the Salbutamol group: the peak bronchodilatation was observed at 30 minutes and the bronchodilation effect was observed in half of the patients up to 6 hours. There were no significant differences between both presentations of Salmeterol. This drug allowed a prolonged bronchodilator effect and is, according to the several consensus on management of asthma, an adequate option in the treatment of moderate to severe asthma.

Abstract
Thirty-seven separate episodes of acute bronchial asthma were studied in 21 asthmatic children. The bronchodilator, cardiovascular, and tremorigenic responses following administration of salbutamol (SAL), terbutaline (TER) and fenoterol (FEN) by closed-port intermittent nebulization were compared for a period of 8 hr. SAL was used at the maximum dose recommended by the manufacturer and TER and FEN at the average doses commonly used in children. Eleven acute attacks were treated with SAL, 12 with TER, and 14 with FEN. Pulmonary function was evaluated by clinical assessment and by the spirometric indices FEV1 and FEF25-75. Tremor was objectively measured, as well as heart rate (HR), respiratory rate, and blood pressure. The onset of bronchodilating effect occurred at 5 min for all three drugs and there were no differences in intensity and duration of bronchodilation between drugs. All three drugs caused rapid onset of tremor (5 min) and this tended to be more intense with SAL. There was a slight decrease in HR in the TER group, whereas SAL and FEN caused increase in HR, with mean values significantly greater than in the TER group from 5 to 30 min after drug administration. Our results indicate that the three short-acting beta 2-agonists studied are equally effective in treatment of acute bronchospasm by the inhaled route in children, in the doses used. Our findings imply that a dose of SAL twice as great as that commonly used by nebulization in children is equipotent to those usually employed for TER and FEN, as far as therapeutic effect is concerned, but it could generate more intense tremorigenic and tachycardic side effects.

Abstract
Fifty-five patients were skin-tested by Multi-Test (M) and needle prick test (NPT) to compare the reproducibility of the methods. We used 6 allergenic extracts: Dermatophagoides pteronyssinus, Dermatophagoides farinae, dog epithelium, cat pelt, American cockroach and mixed molds. A glycerosaline and a positive control (histamine 1 mg/ml) were performed in both methods. Statistically significant differences in histamine and Dermatophagoides farinae wheal reactions between the two methods (M > NPT) were found, with no differences with the other allergenic extracts. We concluded that the two methods are similar with respect to determining the immediate hypersensitivity, but the Multi-Test is better accepted by children.

Abstract
OBJECTIVE To determine the frequency and type of lesions of the temporomandibular joints (TMJ) as well as orthodontic alterations present in patients with juvenile rheumatoid arthritis (JRA). METHODS Twenty-six patients had their TMJ evaluated clinically and by high resolution computer tomography. The patients were also submitted to orthodontic evaluation. Children with isolated malocclusion were used as a control group. RESULTS Computer tomography detected TMJ alterations in 13 (50%) patients with JRA. Bilateral mild lesions were the most frequent. TMJ alterations were especially observed in young patients with JRA with the systemic and polyarticular type of onset. Worse functional class and corticosteroid therapy were also related to TMJ involvement. We observed orthodontic alterations in 18 patients with JRA (69%): midline deviation, convex facial profile. Class II molar relation, crowded lower anterior teeth, anterior open bite, and reduction in the maximum opening of the mouth. Severe TMJ lesions were correlated to cephalometric alterations, suggesting decreased mandibular growth.

Abstract
IL-4 is an essential mediator of IgE synthesis; it also upregulates the expression of the low affinity receptor for IgE (CD23) and its release in soluble form (sCD23). The involvement of IL-4 and sCD23 on the IgE synthesis control has been observed in experimental studies. IL-4 and sCD23 serum levels in asthmatic atopic children were determined in order to investigate a possible correlation between these factors and IgE levels. IL-4, total sCD23 and Dermatophagoides pteronyssinus specific IgE were determined in the serum of 19 asthmatic atopic children (aged 7 to 14) and in 13 age-matched controls. Since sCD23 may present an age-dependent variation, sCD23 and IL-4 serum levels were evaluated in 20 "wheezy babies." IL-4 serum levels were significantly higher in patients as compared to controls, whereas there was no significant difference between them concerning sCD23 levels. sCD23 levels were, however, significantly higher among "wheezy babies" as compared to atopic and nonatopic children. There was no correlation between IL-4 and sCD23 serum levels, nor between any of these factors and IgE levels in all groups. In conclusion, the enhanced IL-4 levels suggest that atopic patients have a preferential activation of Th2 subset. CD23 expression is markedly influenced by age.

Abstract
Forty seven children (6-14 years), with an acute mild or moderate attack of asthma (clinical score 3 or FEV1 > 50% of the predicted), were treated with terbutaline sulphate, by inhalation route with a dry powder inhaler (Turbuhaler - 0,5 mg - group T; N=27, or by a nebulizer 1% solution-in saline-compressed air (6 l/min.) group S; N=20. The children were evaluated at 5, 15, 25 and 30 minutes after the initial treatment. In both groups a significant fall of the clinical score (starting at 15 minutes) (p < 0.05) and a significant improvement of the FEV(1), VC and FEF25-75% (starting at 5 minutes), were observed (p < 0.05). There were no significant changes in heart rates, respiratory rates and blood pressure (p > 0.05). At the end of the first treatment, the number of patients with a FEV(1) < 80% was similar in both groups (T = 13/27 and S = 10/20). The same treatment was repeated, and all the children showed a marked improvement, except for one boy of the group T was hospitalized. In conclusion, children with mild or moderate acute attacks of asthma can be treated up to a week with an inhalation of dry powder, resulting in adequate bronchodilatation without important side effects.

Abstract
Adult female Wistar rats (90 days old; weight 180 to 220 grams) were submitted to different zinc deficient diets (Zn; severe = 2.6 ppm; mild = 9.0 ppm and normal diet = 81.6 ppm), during 6 weeks. After this time they were coupled with normal male Wistar rats. No differences regarding fecundity and sterility were observed between the groups. During pregnancy, part of the animals from severe and mild Zn deficient groups received the same diet and the others received normal diet. The animals from the group receiving normal diet, were divided into other 3: the first received severe, the second mild Zn deficient diet and the third normal diet. During the study we observed that animals submitted to a Zn deficient diet (acute or chronic) had tendency to lower weight gain, lower weight of the offspring, lower serum levels of Zn in maternal and newborn (pool) blood. A significant reduction in the number of alive newborns was observed in the group of animals submitted to severe Zn deficiency. These data reinforces that Zn is a very important trace element overall during pregnancy.

Abstract
In order to determine the etiologic agents involved in atopic diseases in Brazilian children, we have performed this multicentric study in 8 areas in Brazil. We have done prick tests with inhalants and food antigens and analyzed skin tests results, considering positive the wheal mean diameter 3 mm. 22,2% of skin tests were negative and the majority were positive to inhalants: D.pteronyssinus(Dpt) (66.6%) and D. farinae(Df) (66.0%), house dust extract (29.0%), dogs epithelium (19.2%), cat's epithelium (8.8%), feather (5.5%), molds (4.2%), Penicillium sp (2.2%) and Lollium perene (0.6%). We have had 9,1% of food positive tests: cow milk (5.2%), peanut (3.5%), corn (3.2%), cocoa and soya (2.2%), eggs and wheat (1.9%). We have concluded that the domestic mites are the most important agents involved in the etiology of atopic diseases in Brazilian children, and the extracts involved, in line with the sensitization of each geographical area.

Abstract
The prevalence of positive skin prick tests to the mite species Dermatophagoides pteronyssinus, D. farinae, Blomia tropicalis, Chortoglyphus arcuatus, Lepidoglyphus destructor and Aleuroglyphus ovatus was determined in 297 asthmatic adults and children living in seven cities of five Latin American countries. A standardized protocol and a common battery of extracts were used at each site. The mean wheal diameters were measured after 15 min, and those > or = 3 mm were considered positive. Sensitization to D. pteronyssinus varied from 60.7% in Cartagena to 91.2% in São Paulo; to D. farinae from 53.3% in Córdoba to 97.2% in Caracas; to A. ovatus from 26.6% in Bogotá to 71.2% in São Paulo; to B. tropicalis from 46.5% in Mexico City to 93.7% in São Paulo; to C. arcuatus from 33.3% in Mexico City to 75% in São Paulo; and to L. destructor from 30% in Mexico City to 76.2% in São Paulo. This study reported the results of skin test sensitivities in both children and adults. The studies from São Paulo and Córdoba were confined to children and thus could be compared; there was a significantly higher prevalence of cutaneous sensitivity to mite allergens in the children of São Paulo than in those of Córdoba (p < 0.001 for all mite species). Cutaneous sensitivity to mite allergens is very common in young and adult asthmatics in Latin America, in areas both at sea level and at high altitudes. Environmental control measures should be reinforced in the treatment of asthmatics in Latin America.

Abstract
We compared exposure and levels of IgE and IgG antibodies to inhalant allergens in 20 children with asthma and positive skin tests to Dermatophagoides pteronyssinus, living in São Paulo, to 20 control children without history of asthma or allergy and negative skin tests to D. pteronyssinus, D. farinae, and Blomia tropicalis. In 16/20 and 17/20 houses of asthmatic and control children, respectively, at least one sample was obtained which contained > 10 micrograms Der p I/g of dust. Serum IgE antibodies to D. pteronyssinus and Blomia tropicalis were > 200 RAST U/mL in 19/20 and in 16/20 asthmatic children, respectively. In the control group, IgE antibodies to either mite species were < 40 RAST U/mL in most cases. IgG anti-Der p I and anti-Der f I antibodies were detected in 17/20 asthmatics, as opposed to 3/20 controls. Neither cat nor cockroach allergens caused significant sensitization among asthmatic or control children. Although exposure to high levels of mite allergens was common in São Paulo, significant IgE and IgG antibody responses were detected only in children with asthma.

Abstract
OBJECTIVE OF THE STUDY To determine the maximal bronchodilator dose of procaterol and pirbuterol administered by inhalation with an without an aerochamber (Aerocâmera) to children with acute bronchial asthma attacks. TYPE OF STUDY Prospective. 18 children (6-15 years of age) with acute bronchial asthma attacks (FEV1 < 80% of the predicted value) received pirbuterol (N = 10) or procaterol (N = 8) by metered-dose inhaler, one puff every 5 minutes, for a total of five doses. During another acute attack, the same patient received the same medication with the aid of a spacer (Aerocâmera). Clinical evaluation and pulmonary function tests were performed 5 minutes after each inhaled dose. RESULTS For both drugs, maximal bronchodilation was obtained after the second dose. No significant side effects were observed even after procaterol doses of 50 micrograms or pirbuterol doses of 1000 micrograms. The results were unaffected by the use of the spacer. CONCLUSIONS The doses that induced maximal bronchodilation were 400 micrograms pirbuterol and 20 micrograms procaterol. Although the spacer did not change the results, it is a valuable aid for patients who have difficulty in using the metered-dose inhaler (M.D.I.).

Abstract
Thirty-five separate episodes of acute bronchial asthma were studied in 21 asthmatic children. The bronchodilator, cardiovascular, and tremorogenic responses following three modes of administration of salbutamol were compared: open continuous nebulization (ON), closed-port intermittent nebulization (CN), and oral route (OR), for a period of 8 hours. Eleven acute attacks were treated by ON, 11 by CN, and 13 by OR. Pulmonary function was evaluated by clinical assessment and by the spirometric indices FEV1 and FEF25-75. Tremor was objectively measured, as well as heart rate (HR), respiratory rate (RR), and blood pressure (BP). Fastest onset of bronchodilator action, maximal response, and longest duration were seen when the drug was administered by the CN. Onset of tremorogenic effect was registered at 5 minutes when salbutamol was used by CN and ON and at 30 minutes when used by OR. During the first 30 minutes, tremor was significantly greater when salbutamol was used by CN than by OR. There were minor cardiovascular effects, except regarding HR after CN, which was significantly greater than after OR, at 5 and 30 minutes. Our findings indicate the inhaled route as the most effective route for administration of salbutamol to treat acute bronchospasm in children. The use of CN is a good alternative to jet nebulizers, but the greater dose of drug effectively administered by this system can briefly cause more tremor and heart acceleration.

Abstract
Hereditary angioedema (HA) is caused by a quantitative or qualitative deficiency of C1 esterase inhibitor (C1 INH). We present a study of nine patients with HA belonging to two different families. The symptoms started before 10 years of age in most cases (78%). Facial edema (lips, eyes) and of the extremities (feet, hands) were the most frequent complaints. Three patients presented edema of the glottis and one of them underwent a tracheostomy twice. Laboratory tests, outside the acute crisis, revealed low levels of C4 in all patients. The serum levels of C1 INH were normal in seven patients; however, functional activity was not observed in any of them. After the use of a modified androgen (danazol), control of symptoms was observed in all patients, although functional activity was re-established in only five patients.

Abstract
The diagnosis of rheumatic fever (RF) continues to be a difficult one in Pediatrics, mainly because of the polymorphism of its clinical presentation and the lack of specific laboratory test. Among the Jones' major criteria, arthritis is the most frequent and the least specific. Ninety three children with RF who presented 117 flares of the disease were studied in the Department of Pediatrics, Escola Paulista de Medicina, between Dec. 1989 and Dec. 1991. The presence of arthritis was defined as an inclusion criterion. The diagnosis was based on history, physical and laboratory examinations (Modified Jones' Criteria). The mean age was 10 years and the sex ratio was 1 male: 1.4 female. In 45% of the flares, arthritis was the only major criterion. In 44% there were arthritis and carditis, in 7% arthritis and chorea and in 4% arthritis, carditis and chorea. In 64% of the flares the pattern of articular involvement was migratory and in 36% addictive. Polyarthritis and oligoarthritis were observed respectively in 64% and 36%. Monoarthritis was reported in 3%. The definitive diagnosis of RF with atypical articular involvement only was possible in the presence of carditis or chorea. The authors conclude that physicians should be aware of the atypical involvement observed in some cases of RF, specially when arthritis is the only major criterion.

Abstract
Serum and urine penicillin levels were determined in 11 children with rheumatic fever (RF) who were receiving benzathine penicillin G (BPG) prophylactically every 3 weeks and in 10 children without RF who received the drug for the treatment of other infections. The dose given was 600,000 units for children weighing less than 25 kg and 1,200,000 units for those with a weight above 25 kg. Blood and urine samples were collected from both groups before and on days 7, 14 and 21 after BPG administration. Our results showed that: minimum inhibitory concentrations (MICs) of BPG for group A beta-hemolytic streptococci were 0.02 IU/ml or 0.0125 microgram/ml; intramuscular BPG did not give adequate serum levels to block the growth of group A beta-hemolytic streptococci in approximately 24 and 62% of children included in the study on days 14 and 21 after its administration, respectively; BPG metabolism was similar in both groups and did not depend on the underlying disease; serum and urine levels did not vary according to sex and weight; and there was a small correlation between serum and urine levels.

Abstract
Sixteen children with moderate or severe bronchial asthma underwent a double-blind study receiving either ketotifen (K) or placebo (P) in order to verify the sparing effect of K on theophylline. The study lasted 18 weeks. Slow release theophylline was administered to all patients at a dose of 300 mg every 12 hours for the first six weeks of the study ("washout"). From the seventh week on, eight patients received K (1 mg, 2x/day) and the others P. The theophylline dose was maintained and reduced every 4 weeks to 200 mg and 100 mg. The initial clinical characteristics were identical in both groups. The serum levels of theophylline decreased below the ideal range (less than 10 mcg/ml) in groups K and P with a 100 mg dose of theophylline. However, in group K patients, fewer reported worsening of symptoms (number of days with cough and/or wheeze, altered daytime or nighttime peak expiratory flow rate and consumption of beta agonist) when compared to group P. Increased PC20 of methacholine only occurred in group K patients.
