Abstract
The purpose of this study was to evaluate the retention rates of a fissure sealant placed using different adhesive protocols over 24 months. Twenty-four subjects with no restorations or caries received fissure sealants (Clinpro Sealant, 3M ESPE) placed using different adhesive protocols. A total of 292 sealants were placed as follows by two previously calibrated dentists using a table of random numbers (n=73): group I, acid-etch/without adhesive; group II, with a self-etch adhesive (Adper Easy Bond, 3M ESPE); group III, with an etch-and-rinse adhesive (Adper Single Bond 2, 3M ESPE); group IV, with acid + self-etch adhesive (Adper Easy Bond). Two other calibrated examiners independently evaluated the sealants at baseline and at six-, 12-, 18-, and 24-month recalls. Each sealant was evaluated in terms of caries formation being present or absent and retention using the following criteria: 1 = total retention, 2 = partial loss, and 3 = total loss. Pearson's χ2 test was used to evaluate differences in retention rates among the sealants for each evaluation period. At the end of 24 months, total retention rates were 57.5%, 27.4%, 84.9%, and 76.7% in the acid-etch, self-etch adhesive, etch-and-rinse adhesive, and acid + self-etch adhesive groups, respectively. Although there were no statistically significant differences between the retention rates among the adhesive protocols at 6 months ( p=0.684), significant differences were observed at the 12-, 18-, and 24-month evaluations. At 24 months, the lowest retention rates were observed in the self-etch group ( p<0.05). No caries development was observed in any of the groups. The retention rate of sealants placed using self-etch adhesive was poor compared with the other groups.

Abstract
This study evaluates hygiene practices on 53 dairy farms in the Jijel and Blida regions of Algeria. A survey questionnaire was drawn up covering milking conditions and cleaning of the equipment. In parallel, bacteriological analyses were carried out to estimate the rate, source and development of bacterial contamination in raw milk produced on the farm. In addition, screening was performed to detect the presence of inhibitor residues. The results of the survey revealed poor livestock conditions and milking practices that could explain the presence of bacteria in cow's milk. The bacteriological results showed that 76.1% of milk samples taken from cow udders complied with legal standards, compared with only 35.8% of milk samples taken from storage tanks. Moreover, bacterial inhibitors were detected in 28.8% of milk samples. These results showed that the hands of milkers, udders, teat cups, utensils, the water used during milking and the milking environment were all potential sources of milk contamination by the bacteria under investigation. These results suggest that, to improve the bacteriological quality of milk, there is a need to introduce a quality policy which places a premium on milk of high bacteriological quality and aims to generalise good hygiene practices throughout the dairy production chain.

Abstract
OBJECTIVE To compare the 24-month clinical performance of two different resin composites in class II slot restorations. METHODS AND MATERIALS Thirty-seven patients having at least two approximal carious lesions were enrolled in the study. A total of 116 teeth (58 pairs) were restored with either a silorane-based composite (Filtek Silorane) and its self-etch adhesive (Silorane Adhesive System, 3M ESPE) or a methacrylate-based packable resin composite (X-tra Fil) and its self-etch adhesive (Futurabond NR, VOCO GmbH) according to the toss of a coin. The restorations were evaluated at baseline and at six-, 12-, and 24-month recalls by two calibrated examiners according to the modified US Public Health Service criteria. The comparison of the two restorative materials for each category was performed with the Pearson chi-square test. Within group differences of the materials at different recall times were compared using the Cochran Q and Friedman tests. Bonferroni-adjusted McNemar test was used when significant difference was found (p<0.05). RESULTS After 24 months, no statistically significant differences were found between the two restorative materials for the criteria evaluated. CONCLUSIONS Both silorane- and methacrylate-based resin composites showed clinically acceptable performance in class II slot restorations after 24 months.

Abstract
The authors describe a survey and screening programme for staphylococcus. The study covers 14 dairy farms in the Algiers region, from which 203 samples of cows' milk were taken for bacteriological testing. The survey results show that poor husbandry conditions are the main cause of staphylococcus in cows' milk. Staphylococcus was found in the milk of 30% of the cows sampled. These results were influenced by a variety of factors, in that: the contamination rate rose with the number of pregnancies, age, and volume of milk output of the cow, as well as the bedding thickness; the milk contamination rate was greater when milking occurred outside a milking parlour and when it was performed by machine; higher rates of staphylococcus infection were found in the milk of cows at the end of lactation, in red and white breeds, and in those with cylindricalteats. Identification of the bacteria found (staphylococcus) showed that coagulase- negative staphylococci were present in 67.21% of samples, whereas coagulase- positive staphylococci were present in only 32.79%. The average count for the latter was equal to 0.54 x 10(4) colony-forming units per ml of Staphylococcus aureus. Seventy percent of the milk analysed was free from staphylococci and most of the bacteria identified were not pathogenic to consumers (coagulase- negative staphylococci); nevertheless, consuming fresh milk still presents a degree of risk.

Abstract
OBJECTIVE To establish the relationship between the use of acetaminophen and the frequency of asthma in Mexican children in 3 Mexican cities. METHODS Ours was a multicenter, observational, descriptive, cross-sectional study. Patients from 6 to 7 years of age participating in Phase Three B of the ISAAC (International Study of Asthma and Allergies in Children) living in the north of Mexico City, Victoria City, and Merida were included. After adjusting for confounders, we calculated the odds ratios (OR) for the presence of wheezing ever, wheezing in the last 12 months, asthma ever, and the use of acetaminophen in the first year of life and during the last 12 months. RESULTS The ORs for wheezing ever, wheezing in the last year, and asthma ever with respect to use of acetaminophen in the first year of life were not statistically significant (P > .05) in Mexico City, but they were significant in Victoria City (P < .05) and Merida (P < .05). The ORs (95% confidence intervals) for wheezing ever, wheezing in the last year, and asthma ever with respect to use of acetaminophen in the last year were 3.44 (2.96-4.0), 7.97 (5.89-10.78), and 6.10 (3.30-8.81) (P < .05) in Mexico City. Values forVictoria City were 1.36 (1.13-1.63), 3.80 (2.88-5.05), and 2.18(1.57-3.01) (P < .05). Those for Merida were 1.61 (1.40-1.85), 2.07 (1.73-2.48), and 1.53 (1.29-1.82) (P < .05). CONCLUSION The use of acetaminophen is associated with the presence of wheezing and asthma in 3 different cities in Mexico.

Abstract
OBJECTIVE To elaborate Mexican growth charts based on international methodology. DESIGN Data were obtained from the Mexican National Health Survey. The survey was stratified and probabilistic representative of all the country. SETTING Nationwide open population living in urban and rural areas. SUBJECTS Boys (8545) and girls (9983) from 10 to 18 years participating in the survey. METHODS Age, weight and height were recorded. Empirical percentiles were calculated and smoothed. Smoothed curves were approximated using least-mean square estimation. RESULTS Tables and figures for percentile values of weight, height and body mass index (BMI) for age, as well as percentile values of weight and BMI for height for both genders are presented. Regarding 50th BMI for age percentiles, Mexicans had higher levels than the Americans in the Centers for Disease Control and Prevention growth charts; Mexicans were lower but had similar weights than the Americans. Owing to the high BMI, the percentile corresponding to an overweight level (25 kg/m(2)) at 18 years was 74.5 in boys and 72.5 in girls, whereas obesity level (30 kg/m(2)) at 18 years was 97.3 and 97.4 in boys and girls, respectively. CONCLUSIONS The present growth charts are snapshots of a Mexican population. Because of the high median BMI compared to US and World Health Organization standards, we must be cautious in establishing an upper normal cutoff for clinical normality, not merely selecting the 85th and 95th percentiles as equivalents of overweight and obesity, respectively. Therefore, we proposed percentiles 74.5 in boys and 72.5 in girls as the action points of overweight as they are the percentiles corresponding to BMI 25 kg/m(2) at 18 years. SPONSORSHIP The survey was supported by the Mexican Minister of Health. Statistical analyses were sponsored by Dr Del-Rio-Navarro.

Abstract
BACKGROUND The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire allows users to find factors associated with allergic diseases, but thus far most of the studies on risk factors for allergic diseases have been devoted to asthma and not to rhinitis. OBJECTIVE To determine the main factors associated with symptoms of allergic rhinitis and rhinoconjunctivitis in school children and adolescents in northern Mexico City. PATIENTS AND METHODS A cross sectional, multicenter survey was conducted in northern Mexico City, in children aged 6-7 and 13-14 years. The survey instrument was the Phase Three B ISAAC questionnaire, which was validated and standardized in Spanish. RESULTS There were 4106 6-7-year-olds and 6576 13-14-year-olds. The total prevalence of diagnosis of allergic rhinitis was 4.6%. The prevalence of cumulative and current symptoms of rhinitis was considered high (>29%), but the prevalence of the diagnosis of allergic rhinitis was considered low (ranging from 3.4% to 5.6%). The prevalence of symptoms of rhinitis with conjunctivitis had intermediate values (ranging from 20.3% to 30.2%). Cumulative symptoms of allergic rhinitis, current symptoms of allergic rhinitis, and rhinoconjunctivitis were related to symptoms of current or cumulative asthma, symptoms of current or cumulative atopic eczema, and current use of paracetamol (odds ratio > 1, P < .05). CONCLUSION The present results support the concept of rhinitis and asthma as common chronic respiratory diseases, and this study also found a relation between paracetamol use and rhinitis in children.

Abstract
BACKGROUND Zinc (Zn), copper (Cu) and manganese (Mn) are involved in regulatory systems in the cell. Their role in neuromodulator activities and redox reactions has been implicated in the pathogenesis of neurological disorders. The aim of this study was to determine changes of Zn, Cu and Mn levels in brain tissue, blood and urine after experimental subarachnoid haemorrhage (SAH). The possible importance of these trace minerals on the pathogenesis of SAH was also discussed. METHOD Rats were divided into three groups; namely a SAH group, a control group and a normal group. Blood samples in the SAH group and normal saline in the control group were injected into the cisterna magna. No surgical procedures were performed on the normal group. Brain tissue, blood and urine samples were measured for trace minerals by atomic absorption spectrophotometry. Measurements were taken on days 3, 7 and 10 after the onset in the control and SAH groups, and on the first day in the normal group. FINDINGS The reduced blood Zn levels and increased Zn urine loss observed in the SAH group were conspicuously significant. Furthermore, significant changes in Mn levels were also seen at different stages of the trial in the SAH group. However, differences found in the Cu levels between the groups were not significant enough to explain the results. INTERPRETATION These results suggest that the low blood Zn levels seen throughout the stages, the low brain tissue Mn levels seen during the latter part of the trial, and the low blood Mn levels observed during the early stages, may all be related to an increased risk in experimental SAH in rats. These differences may have possible role in the pathogenesis of SAH, and further investigations into the reduced blood Mn levels observed during the study may lead to new insight into the treatment of SAH.

Abstract
BACKGROUND Asthma is an important childhood disease. Recent surveys of the International Study of Asthma and Allergies in Childhood (ISAAC) suggest that the prevalence of asthma is increasing but these surveys do not include any pulmonary tests to confirm the possible diagnosis of asthma. OBJECTIVE To compare bronchodilator reversibility with the albuterol test in symptomatic and asymptomatic 6-7-year-old children with asthma participating in the ISAAC survey and living in Mexico City. PATIENTS AND METHODS We performed an observational, descriptive, comparative, cross sectional study in children participating in phase 3b of the ISAAC study. According to the ISAAC questionnaire children were classified as asthma symptomatic or asymptomatic. Both groups had bronchodilator reversibility with the albuterol test, using the guidelines of the American Thoracic Society to confirm or rule out the diagnosis of asthma. RESULTS The asymptomatic group had a baseline FEV1 of 1.70 +/- 0.34 l/sec (mean +/- SD) and an endpoint FEV1 of 1.76 +/- 0.42 l/sec; in the symptomatic group the respective values were 1.51 +/- 0.41 l/sec and 1.57 +/- 0.44 l/sec (p < 0.05). A positive reversibility test was found in 13/136 (9.6 %) children in the asymptomatic group and in 22/112 (19.6 %) children in the symptomatic group (p < 0.05). CONCLUSION Because of its low sensitivity, bronchodilator reversibility cannot be considered a diagnostic tool to confirm diagnosis of asthma.

Abstract
BACKGROUND Previous studies have revealed the relationship between asthma and obesity, but the relationship with other markers of overweight and obesity has not yet been investigated. OBJECTIVE To establish the relationship between asthma symptoms and simple anthropometric indexes (BMI, waist circumference (WC), and waist-to-hip ratio (WHR)) as markers of overweight in an adult Hispanic population. METHODS The data were obtained from the PRIT (Prevalence of Cardiovascular Risks in General Hospital Workers) 2001 survey. The participants were workers at the Hospital General de México in Mexico City and included 135 men and 398 women aged 43.8 +/- 11.9 and 43.0 +/- 10.5, respectively. Odds ratios for asthma symptoms at different BMI, WC, and WHR cutoff points associated with excessive weight were calculated. The likelihood ratios for having asthma symptoms in participants with various cutoff values of BMI, WC, and WHR also were calculated. RESULTS Asthma symptoms were not related to anthropometric markers of overweight or obesity in men, while they were associated in women with WC cutoff levels of 80 and 85 cm, and BMI of 25 and 27 kg/m2. No level of WHR was related to asthma symptoms in women. In women, the likelihood ratio for asthma symptoms increased proportionally from WC levels of 73.5 cm up to 86 cm, while this risk increased significantly from BMI levels of 22 up to 29 kg/m2. CONCLUSION Overweight as assessed by BMI and WC (but not WHR) was related to asthma symptoms in women in the studied population.

Abstract
The aim of the study was to determine the chromium concentrations of soil and plant specimens taken from a rural area exposed to cement factory emissions and also to determine the blood concentrations and sensitivity conditions observed in humans residing in this rural area. The study was carried out in Cukurhisar, a town in Eskisehir-Turkey, between May 2000 and March 2001. Besides the 108 soil (36 for control) and plant specimens, which were taken from eight different directions from the cement factory, blood samples of the individuals residing in this area were taken from 258 subjects (258 for control) following a physical examination, and patch tests were also applied. The chromium concentrations of the soil and plant specimens taken from different places in different directions of the factory were higher than in the control areas. The physical examination of subjects did not reveal results different from those of the control group except for the diagnosis of contact dermatitis. The analyses of venous blood samples showed that chromium concentrations were found to be within the reference values given for both groups, but higher in the subjects (P<0.001). According to the results of patch tests, sensitivity to chromium was found to be more frequent for the subject group than the control group (P<0.05). According to these results, clinical tools revealed no toxic effects for the subjects, except contact dermatitis. However, sensitivity to patch tests showed that this subject group has been affected compared to the control group and that this effect increased with age.

Abstract
BACKGROUND Recurrent acute respiratory tract infections (RARTIs) in children are related to IgG subclass deficiencies. The aim of the trial was to evaluate the effect of OM-85 BV in the number of RARTIs as well as in the IgG subclass levels. METHODS This was a randomized, double-blind, placebo-controlled clinical trial. Patients of ages three to six years, having three or more documented ARTIs during the last six months with subnormal IgG subclass levels were included. Patients took either one capsule of OM-85 BV (3.5 mg) or placebo orally every day for ten consecutive days per month during three consecutive months. Patients were followed three further months without drug intake. IgG subclass levels were determined before and after treatment. RESULTS IgG4 levels diminished after the OM-85 BV treatment (-3 [-8.0, -1.0] median difference [95 % CI] p < 0.05 by Wilcoxon test). No other significant changes in IgG subclasses were observed. After six months the patients in the OM-85 BV group (n = 20) experienced 2.8 1.4 (mean SD) ARTIs, while the patients in the placebo group (n = 20) suffered 5.2 1.5 ARTIs (-2.4 [3.3, -1.5] mean difference [95 % CI] p < 0.001 by Student's t test). Three patients with OM-85 BV had gastrointestinal events related to drug administration, as well as three placebo patients. CONCLUSION This study demonstrated the clinical benefit of OM-85 BV in patients suffering from RARTIs and subnormal levels of IgG subclasses. This trial opens new perspectives in the research of the mechanism of action of OM-85 BV.

Abstract
BACKGROUND Several immunostimulants presume to prevent respiratory tract infections (RTIs) in children, but their efficacy is controversial. OBJECTIVES To compile the findings of the randomized, placebo-controlled trials (RCTs) on the prevention of acute respiratory tract infections (ARTIs) in children using immunostimulants, and to perform a meta-analysis. DATA SOURCES Medline, EMBASE databases, and register of Cochrane Acute Respiratory Infection Group. REVIEW METHODS We searched all the references of immunostimulants and selected papers referring to RCTs on the prevention of ARTIs in children. Papers were rated according to Jadad's instrument. We abstracted the number of ARTIs, and a one-tailed probability value (p) was abstracted for each trial. Effect of medication was determined as weighted mean +/- SE of percent reduction of ARTIs regarding ARTIs of placebo groups as 100%. RESULTS Four of five RCTs with Jadad's score > 3 showed significant reduction of ARTIs in immunostimulant groups. When only the trials reporting mean +/- SD and/or dispersion were considered (n = 16), the global weighted percent effect of immunostimulants showed a change of -42.64%, with 95% confidence intervals from -45.19% to -40.08%; i. e., the treated group presented about 60% of the mean number of ARTIs in the placebo group. CONCLUSIONS According to this meta-analysis and RCTs with Jadad's score > 3, immunostimulants are an effective treatment for the prevention of ARTI. Further high-quality RCTs are required to demonstrate the effect and the size of the effect of each individual immunostimulant.

Abstract
This study evaluated the safety and efficacy of the immunostimulatory agent OM-85 BV in 112 male car-factory workers who were highly susceptible to acute respiratory tract infections (ARTIs), each having experienced > or = 4 ARTIs during 1999. From January to March 2000, each worker received one capsule of OM-85 BV (7 mg) per day for 10 consecutive days each month. The patients were followed for a further 9 months. Mean number of ARTIs decreased from 8.2 +/- 2.1 per worker in 1999 to 5.3 +/- 2.9 in 2000; i.e. a difference of -2.9 (95% confidence intervals, -3.5 to -2.4). Similar effects were observed in men who had different job roles, and no adverse events were reported during drug administration. We concluded that OM-85 BV appears to be safe and effective in reducing the incidence of ARTIs in susceptible workers, although further double-blind, placebo-controlled clinical trials are required.

Abstract
OBJECTIVE To determine values of simple anthropometric measurements which are associated with the presence of type 2 diabetes mellitus, hypertension and dyslipidaemia and to assess anthropometric cut-off values for predicting the likelihood of these chronic conditions in a Mexican population. DESIGN AND SETTING The data were obtained from PRIT (Prevalence of Cardiovascular Risk Factors in General Hospital Workers) surveys from 1994 to 2000 adjusted to the structure of the overall Mexican population. SUBJECTS A total of 2426 men and 5939 women aged 38.99+/-7.11 and 39.11+/-14.25 y, respectively. MEASUREMENTS The optimal sensitivity and specificity of using various cut-off values of BMI (body mass index), WHR (waist-to-hip ratio), WC (waist circumference) and WTH (waist-to-height ratio) to predict type 2 diabetes mellitus (DM), hypertension (HT), or dyslipidaemia were examined by receiver operating characteristic curve (ROC) analysis. The likelihood ratios for having diabetes, hypertension and dyslipidaemia in subjects with various cut-off values of BMI, WHR, WC and WTH were calculated. Multiple step-wise logistic regression analysis was used to examine the independent relationship between the anthropometric indexes, age and smoking, and the odds ratio of having chronic conditions. RESULTS The BMI cut-off to predict DM, HT, or dyslipidaemia varied from 25.2 to 26.6 kg/m2 in both men and women. The optimal WC cut-offs were 90 cm in men and 85 cm in women. The WHR cut-off was about 0.90 in men and 0.85 in women, and the optimal WTH cut-off was 52.5 in men and varied from 53 to 53.5 in women. The cut-off levels for WC, WHR and WTH corresponded to the inflexion points in the likelihood ratio graphs. In the case of BMI likelihood ratio graphs, we found a significant increase in the risk for chronic conditions from 22 to 23 BMI levels in both genders. Logistic regression analyses disclosed that only BMI and age were included in all the models as well as the influence of smoking in DM and dyslipidaemia in men. CONCLUSION Although these results may not be readily applied to the rest of the Mexican population or to other Hispanic populations, they point to the necessity of similar studies with large randomized samples to find the cut-off levels for chronic conditions in different populations.

Abstract
BACKGROUND The use of short-acting beta2-agonists is associated with oral mucosa injuries that are probably provoked by decreased saliva flow and decreased concentrations of immunoglobulin (Ig)A in saliva. OBJECTIVES To explore the effect of salmeterol, alone or combined with beclomethasone, on the health of oral mucosa, as well as its effect on saliva flow and IgA concentration in saliva. METHODS Patients ranging in age from 6 to 15 years with moderate-persistent chronic asthma were enrolled. Patients received two 6-week treatments, one with salmeterol plus beclomethasone and the other with only salmeterol, with a 1-week washout period between treatments. Patients had oral cavity examinations and assessments of saliva flow, IgA in saliva, and total protein in saliva before the beginning and at the end of each treatment RESULTS The results of the baseline oral examinations were normal in all patients. The postsalmetrol (PS) examinations detected 13 patients with gingivitis and the postbeclomethasone-salmeterol (PBS) examinations disclosed 10 patients with gingivitis and 1 with lower-lip ulceration. Baseline saliva flow was 16.25 +/- 7.04 mm/minute (confidence interval [CI] 95% 13.67; 18.89), PS was 13.53 +/- 5.93 mm/minute (CI 95% 11.33; 15.73), and PBS was 16.57 +/- 5.54 mm/minute (CI 95% 14.51; 18.62). No statistical differences between the different assessments were found. Mean saliva IgA at baseline was 4.99 +/- 1.96 mg/dL (CI 95% 4.26; 5.71), PS IgA was 6.53 +/- 3.02 mg/dL (CI 95% 5.41; 7.65), and PBS IgA was 4.82 +/- 1.98 mg/dL (CI 95% 4.08; 5.56). PS IgA was significantly higher than the other two determinations (P < 0.05 by Bonferroni and Tukey tests). Baseline saliva IgA-to-protein ratio was 0.72 +/- 0.24 (95% CI 0.64; 0.80), PS IgA:protein ratio was 1.02 +/- 0.38 (95% CI 0.88; 1.16), and PBS IgA:protein ratio was 0.72 +/- 0.25 (95% CI 0.62; 0.82). PS IgA:protein ratio was significantly higher than the other two determinations (P < 0.05 by Bonferroni and Tukey tests). CONCLUSIONS In the present study it was demonstrated that salmeterol alone or in combination with beclomethasone induced injuries in the oral mucosa, but only salmeterol alone induced increases in the total and protein-adjusted IgA in saliva.

Abstract
BACKGROUND Acute respiratory tract infections (ARTIs) are among the main causes of morbidity and mortality in children. The bacterial extract OM-85 BV (bronchovaxom) has shown protective effect for ARTIs on children. We report a double-blind, placebo-controlled, parallel, prospective clinical trial to assess the safety and efficacy of two courses of OM-85 BV in the prevention of ARTIs in susceptible children during 12 months. METHODS Fifty-four susceptible children from 1 to 12 years of age living in the metropolitan area of Chihuahua City were selected. They were randomized to receive either OM-85 BV or placebo (one capsule a day for 10 days a month for 3 consecutive months) at the beginning of the trial and 6 months later with the same schedule. Patients were followed up for 12 months, including the administration period. The trial began in July 1997 and ended in April 1999. RESULTS The number (mean +/- SD) of ARTIs was 5.04 +/- 1.99 (median, 5.0) in the OM-85 BV group vs 8.0 +/- 2.55 (median, 8.0) in the placebo group, with a mean difference of - 2.96 (95% confidence interval [CI], - 4.22 to - 1.7). The number of antibiotic courses was 2.46 +/- 2.08 (median, 1.5) in the treatment group vs 4.46 +/- 2.08 (median, 4.0) in the control group, a difference of - 2.0 (95% CI, - 3.14 to - 0.86). The total duration of ARTIs was 35.23 +/- 17.64 days (median, 30.5 days) in the OM-85 BV group vs 60.75 +/- 25.44 days (median, 55.0 days) in the placebo group, ie, a difference of - 25.52 days (95% CI, - 37.56 to - 13.47 days), p < 0.001 by Student's t test and Mann-Whitney U test for all the items. Four patients in the OM-85 BV group had five adverse events. Only one episode of skin rash was related to the medication intake. Six patients in the control group had six adverse events. CONCLUSIONS OM-85 BV had a preventive effect on ARTI in the susceptible children for 12 months with an important reduction on the antibiotic requirements and the number of days of suffering ARTIs.

Abstract
OBJECTIVE To evaluate the weight gain after Sibutramine 10 mg daily discontinuation. To evaluate the effect of Sibutramine 10 mg daily in patients who were on a diet for 6 months. DESIGN After a double-blind, placebo-controlled, parallel, prospective phase for 6 months, the treatments were crossed over and the patients continued in double-blind observation for another 6-month period. SUBJECTS Forty out of 44 patients who were on Sibutramine and 42/44 who were on placebo switched the trial medication. All the patients were obese at the beginning of the trial (body mass index, BMI>30 kg/m(2)). During the first phase, the weight loss in the Sibutramine group was 7.52 kg (95% confidence intervals (95% CI) 6.15; 8.9) and that in the placebo group 3.56 kg (95% CI 2.41; 4.7) (using last observation carried forward (LOCF)). MEASUREMENTS Body weight, BMI, waist, medical history, assessment of hunger, satiety and diet compliance, standard laboratory assessments, blood pressure, heart rate and ECG. RESULTS Thirty out 40 patients in the Sibutramine/placebo (S/P) group and 32 out of 42 in the placebo/Sibutramine (P/S) group completed the second phase of the trial. During the second part of the trial the S/P gained 3.21 (95% CI 2.15; 4.26) kg, 1.21 (0.82; 1.59) kg/m(2), and 2.83 (1.55; 4.12) waist cm. The P/S group lost 1.62 (2.62; 0.61), 0.67 (1.09; -0.25) kg/m(2), and 1.85 (3.18; 0.53) waist cm. Eleven patients in the S/P group suffered 14 adverse events, mainly blood pressure increase (n=4); 19 patients in the P/S group had 29 adverse events, mainly dry mouth (n=8), constipation (n=5) and blood pressure increase (n=4). Only one P/S patient withdrew because of an adverse event. CONCLUSIONS After Sibutramine discontinuation patients had weight gain but they did not reach the baseline body weight. No significant adverse events presented after Sibutramine discontinuation. When Sibutramine was administrated to patients after 6 months of diet, the weight plateau was broken. Early Sibutramine administration had better effects than late post-diet administration. Sibutramine was well tolerated by the patients.

Abstract
OBJECTIVE The objective of this study was to compare the prevalence of overweight and obesity in the first Prevalencia de factores de nesso cardiovascular en Trabajadores survey (1994) with the prevalence of overweight and obesity observed in the second survey (1996). RESEARCH METHODS AND PROCEDURES For both surveys the following individual data were collected: age, sex, weight, height, and body mass index (BMI). The 1994 survey included 2383 people and the 1996 survey included 2759 people. The degree of BMI was classified according to the current World Health Organization definitions. The population was divided by gender and age group, and the prevalence of each level of overweight was calculated. Additionally, the prevalence of different cutoff levels of BMI was calculated by gender and age groups. RESULTS The global prevalence of age-adjusted overweight increased from 26.91% to 37.45%. This increase was observed in both genders but the men had a higher increase from 24.51% to 40.21%. Overweight was more frequent in men than in women in all age groups. Male overweight prevalence was higher in the 40- to 59-year-old group and > or = 60-year-old group. Female overweight prevalence was predominant in the 30- to 39-year-old, 40- to 49-year-old, and 50- to 59-year-old groups. Global prevalence of obesity (> or =30 kg/m(2)) changed from 13.8% to 17.2%. Particularly, global prevalence of obesity class I increased from 9.66% to 12.6%; in men this figure increased from 9.04% to 13.05% and in women from 9.9% to 12.71%. DISCUSSION Prevalence of overweight and obesity has increased significantly in the studied population. It is necessary to implement lifestyle modifications to prevent the increase of prevalence of overweight and obesity.

Abstract
Asthma morbidity and mortality has increased. One of the possible causes is the excessive use of beta agonists. The aim of this study is to compare the effects of six week treatment with beclomethasone alone (Ibec) or the combination of beclomethasone-salmeterol (Ibe + Isal) on serum potassium (K), CPK-MB and ECG in children suffering asthma. It was a prospective, randomised, open cross-over trial. Patients received either Ib2 (2 puff/12 hr, 100 micrograms per puff) or Ibe + Isal (B 2 puff/12 hr, 100 micrograms per puff and S 2 puff/12 hr, 25 micrograms per puff) with dose meter inhaler by 6 weeks, with a four-week wash-out period between the treatments. K, CPK-MB and ECG were assessed at baseline, and after each treatment period. There were 9 girls and 20 boys, aged 11 +/- 2.18 (mean +/- SD) years, baseline K was 4.57 +/- 0.43 mEq/l, after B K 4.38 +/- 0.39 IU and after BS K 4.38 +/- 0.40. The CPK-MB level were baseline 14.75 +/- 4.5, after B 20.10 +/- 6.9 and after BS 21 +/- 8.05 (p < 0.05). Baseline QTc was 0.416 +/- 0.02 msec, after B 0.425 +/- 0.027, and after BS 0.415 +/- 0.029. We conclude that the treatment of children with asthma with 400 micrograms per day of Ibec or concomitantly with 100 micrograms of Isal for 6 weeks does not alter the serum K+ or the QTc. However, the CPK-MB has a significant increment with both treatments but without clinical and/or ECG changes. We can't affirm that Ibec or Ibec plus Isal have a cardiotoxic side-effect by the only presence of high levels of CPK-MB. We agree that it is necessary a close follow up of these apparently asymptomatic patients not induce important cardiovascular changes although CPK-MB was increased.

Abstract
BACKGROUND Acute respiratory tract infections (ARTIs) are among the main causes of morbidity and mortality in children. The bacterial extract OM-85 BV has shown some protective effect for ARTIs in preschool children and a reduction in exacerbations of chronic bronchitis in adults. OBJECTIVES This trial reports results of a double-masked, placebo-controlled, parallel-group clinical study that assessed the efficacy and tolerability of OM-85 BV in the prevention of ARTIs in school girls living in an orphanage. METHODS Two hundred girls (age range, 6 to 13 years) living in an orphanage entered the trial. Participants were randomly allocated to receive either OM-85 BV or placebo for 10 consecutive days a month for 3 consecutive months. Patients were followed up for 6 months, including the administration period. The trial began in September 1996 and finished in March 1997. Primary end points were the type and number of infections. Secondary end points included when an infection occurred, time to clinical cure, severity of infection, absenteeism from school due to an ARTI, number of antibiotics or other drugs prescribed, and duration of concomitant drug treatment. RESULTS During the trial, patients in the OM-85 BV group experienced 143 ARTIs (135 upper ARTIs and 8 otitis episodes) and patients in the placebo group experienced 299 ARTIs (273 upper ARTIs, 1 lower ARTI, and 25 otitis episodes). The median number of ARTIs was 1.0 (0.0, 3.0; 5th percentile, 95th percentile) in the OM-85 BV group compared with 3.0 (2.0, 4.0; 5th percentile, 95th percentile) in the placebo group. This difference was statistically significant (P < 0.001). Participants who received OM-85 BV also showed significantly better results (P < 0.001) than participants who received placebo in terms of median duration of illness, median number of missed school days due to an ARTI, median number of antibiotic and drug courses, and median duration of concomitant treatment. There were significant differences (P < 0.05) in severity of ARTIs during month 4 of the trial, with patients receiving OM-85 BV showing less severe ARTIs than patients receiving placebo and shorter mean time to clinical cure from the second month to the fourth month. No adverse events related to the trial medications were reported. CONCLUSIONS OM-85 BV had a preventive effect on ARTIs in the school girls, with a reduction in the antibiotic requirements and the duration of ARTIs. Future studies are needed to further explore the role of OM-85 BV in the prevention of ARTIs.

Abstract
OBJECTIVE To evaluate the safety and efficacy of Sibutramine 10 mg per os, once a day in obese patients over a period of 6 months. DESIGN A monocenter, double-blind, placebo-controlled, parallel, prospective clinical trial. SUBJECTS 109 male and female obese patients (BMI>30 kg/m2) from 16 to 65 y entered the trial. MEASUREMENTS Body weight, body mass index (BMI), waist and waist/hip ratio, medical history, assessment of hunger, satiety and diet compliance, standard laboratory assessments, blood pressure, heart rate and ECG. RESULTS 40 out of 55 patients in the Sibutramine group and 44 out of 54 patients in the placebo group completed the trial. Using the method of last observation carried forward (LOCF), the weight loss in the Sibutramine group was 7.52 kg (95% confidence intervals (95% CI) 6.15; 8.9) and that in the placebo group was 3.56 kg (95% CI 2.41; 4.7). The BMI loss was 3.14 kg/m2 (95% CI 2.58; 3.69) in the Sibutramine group and 1.46 kg/m2 (95% CI 0.99; 1.93) in the placebo group. The waist reduction was 12. 51 cm (95% CI 9.25; 15.77) in the Sibutramine group and 3.26 cm (95% CI 1.38; 5.14) in the placebo group (P<0.05 by paired Student's t-test for all the intragroup comparisons). 32 Sibutramine patients had 45 adverse events, the most frequent adverse events in the Sibutramine group being dry mouth (n=19), increase in blood pressure (n=5), constipation (n=5) and tachycardia (n=5); 23 placebo patients had 29 adverse events, mainly increase in blood pressure (n=11) and dry mouth (n=10). Two Sibutramine patients withdrew from the trial due to adverse events. CONCLUSION Sibutramine induces significant loss of body weight, BMI and waist, but does not significantly affect cardiovascular function. Sibutramine was well tolerated by most of the patients.

Abstract
OBJECTIVE To evaluate the safety and efficacy of sibutramine 15 mg by mouth once per day in obese patients over a period of 6 months. RESEARCH METHODS AND PROCEDURES A monocenter, double-blind, placebo controlled, parallel, prospective clinical trial was carried out. Sixty-nine male and female obese patients (body mass index [BMI] > 30 kg/m2) aged 16 to 65 years entered the trial. RESULTS 22 of 35 patients in the sibutramine group and 9 of 34 patients in the placebo group completed the trial. The high dropout rate in the sibutramine group was due to adverse events in 3 cases, lack of efficacy (as judged by patients) in 7, loss to follow-up in 2, and an orthopedic device being worn in 1; in the placebo group the dropouts were ascribed to lack of efficacy (as judged by patients) in 17 cases and to loss to follow-up in 8 cases. Using the method of last observation carried forward, the weight loss in the sibutramine group was 10.27 kg (95% confidence intervals [95% CI] 7.66; 13.07) and 1.26 kg (95% CI 0.3; 2.23) in the placebo group. The BMI loss was 4.17 kg/m2 (95% CI 3.11; 5.22) in the sibutramine group and 0.53 kg/m2 (95% CI 0.13; 0.92) in the placebo group. The waist circumference reduction was 12.51 cm (95% CI 9.25; 15.77) in the sibutramine group and 3.26 cm (95% CI 1.38; 5.14) in the control group (p<0.05 by paired Student's t test for all the intragroup comparisons). Twenty-three sibutramine patients had 34 adverse events, the most frequent adverse events in the sibutramine group were upper respiratory tract infections (n = 6) and constipation (n = 6); 16 placebo patients had 21 adverse events. Three sibutramine patients withdrew their informed consent when they had adverse events. DISCUSSION The results show that sibutramine induces significant loss of body weight and waist circumference. Cardiovascular function was not significantly affected by sibutramine. Sibutramine was well tolerated by most of the patients.

Abstract
A 6-month double-blind, prospective, randomized, placebo-controlled trial was conducted to establish the safety and efficacy of OM-85-BV in the treatment of subacute sinusitis and in the following prevention of the respiratory tract infections in 56 children from 18 months to 9 years of age. In the subacute phase of the sinusitis the patients were given one OM-85-BV capsule (3.5 mg of bacterial extracts) (n = 26) or placebo (n = 30), daily for ten days; additionally both groups took amoxicillin/clavulanate 40/10 mg/kg daily in three divided doses for 21 days. For the following two months the patients took one OM-85-BV capsule or placebo, ten days a month. In the subacute phase the OM-85-BV group of patients improved sooner (5.56 +/- 4.98 vs 10 +/- 8.49 days) and had a shorter convalescence (15.38 +/- 8.91 vs 20.28 +/- 7.17 days). During the six month follow-up the patients in the OM-85-BV group had a lower number of infections (1.56 +/- 0.3 vs 2.22 +/- 0.43) and required a lower number of drug treatments (1.47 +/- 0.32 vs 1.94 +/- 0.42). One patient treated with OM-85-BV presented a mild rash which disappeared three days after the drug discontinuation. We conclude that OM-85-BV is safe at pediatric ages, as well as accelerates the cure and improvement of subacute sinusitis while it lowers the incidence of respiratory infections.

Abstract
Mepyramine-theophylline-acetate (MTA), a theophylline derivative combined with an antihistamine, is used to treat patients with asthma. A double-blind, randomized, prospective, parallel-group study was conducted to evaluate the efficacy and safety of MTA in the treatment of asthmatic crisis in children 2 to 6 years of age. Forty patients with mild-to-moderate asthma were admitted to the study. The MTA group received 8 mg/kg per day of MTA by mouth in three divided doses for 7 days. The other group received 50 microL/kg per day of placebo in three divided doses for 7 days. Salbutamol (albuterol) syrup was used as the rescue drug if manifestations of asthma persisted. Both the MTA group and the placebo group had similar demographic characteristics at baseline. Both groups showed improvement of the asthma symptoms (cough, dyspnea, hypoventilation, and wheezing), as evaluated by the investigators at days 3 and 7. Patient diary scores showed earlier improvements in the MTA group than in the placebo group. Both groups showed improvement in peak flow at days 3 and 7 (P = 0.005). The control group used more doses of salbutamol than the MTA group on days 2 through 6 and globally (mean +/- SD, 6.79 +/- 9.11 doses vs 1.29 +/- 2.23 doses). The improvements in the placebo group were thought to be due to salbutamol. Three MTA patients dropped out of the trial, one because the parents felt that the treatment was not effective and two because of gastrointestinal manifestations (epigastric discomfort and vomiting). In the placebo group, two patients dropped out. One patient had epigastric discomfort and the other had to be treated in the emergency department for an exacerbation of the asthma. We conclude that MTA may be a good therapeutic option for the treatment of asthmatic crisis in children 2 to 6 years of age.
