Clinical profile of bronchiolitis in infants younger than 90 days in Saudi Arabia.

BACKGROUND: Bronchiolitis is a self-limiting disease of children caused by viral infections of the small airways with a wide spectrum of illness severity. Search of the literature reveals a need for refinement of criteria for testing for concomitant severe bacterial infections as well as appropriate therapeutic interventions for patients <90-day-old diagnosed with clinical bronchiolitis. We believe that a better understanding of the disease spectrum will help optimize health-care delivery to these patients. AIMS: The aim of this study was to determine the clinical profile at presentation, disease course and outcome of bronchiolitis in <3-month-old infants who presented to our Pediatric Emergency Department (PED) during one disease season. SETTINGS: Retrospective chart review during one bronchiolitis season, from November 1, 2011 to April 20, 2012. SUBJECTS: All <90-day-old infants presenting with clinical bronchiolitis presenting to Urban PED of a tertiary care university hospital during one bronchiolitis season. MATERIALS AND METHODS: A retrospective chart review based on computer records of all emergency department visits of infants less than 90 days with a clinical diagnosis of bronchiolitis, covering the period between November 1, 2011 and April 30, 2012. RESULTS: Out of the total of 1895 infants <90 days of age, 141 had a clinical diagnosis of bronchiolitis and 35 needed admission to hospital. Blood for culture was obtained from 47 infants, urine for culture was obtained from 46 infants and cerebrospinal fluid for culture was obtained from eight infants. One case of bacteremia was documented, but this was found to be a contaminant. No cases of meningitis occurred among these infants. However, one infant had a positive urine culture consistent with infection (Escherichia coli). CONCLUSION: Based on the results, it can be conclude that the risk of bacteremia or meningitis among infants <90 days of age with fever and bronchiolitis is low. The risk of urinary tract infection in this age group is also low, but it is higher than the risk for meningitis or bacteremia. Our data for admission and treatment guidelines are similar to those published from other countries.

Short-term late-generation antibiotics versus longer term penicillin for acute streptococcal pharyngitis in children.

BACKGROUND: The standard duration of treatment for children with acute group A beta hemolytic streptococcus (GABHS) pharyngitis with oral penicillin is 10 days. Shorter duration antibiotics may have comparable efficacy. OBJECTIVES: To summarize the evidence regarding the efficacy of two to six days of newer oral antibiotics (short duration) compared to 10 days of oral penicillin (standard duration) in treating children with acute GABHS pharyngitis. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2012, Issue 3) which contains the Cochrane Acute Respiratory Infections Group's Specialized Register, MEDLINE (January 1966 to March week 3, 2012) and EMBASE (January 1990 to April 2012). SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing short duration oral antibiotics to standard duration oral penicillin in children aged 1 to 18 years with acute GABHS pharyngitis. DATA COLLECTION AND ANALYSIS: Two review authors scanned the titles and abstracts of retrieved citations and applied the inclusion criteria. We retrieved included studies in full, and extracted data. Two review authors independently assessed trial quality. MAIN RESULTS: We included 20 studies with 13,102 cases of acute GABHS pharyngitis. The updated search did not identify any new eligible studies; the majority of studies were at high risk of bias. However, the majority of the results were consistent. Compared to standard duration treatment, the short duration treatment studies had shorter periods of fever (mean difference (MD) -0.30 days, 95% confidence interval (CI) -0.45 to -0.14) and throat soreness (MD -0.50 days, 95% CI -0.78 to -0.22); lower risk of early clinical treatment failure (odds ratio (OR) 0.80, 95% CI 0.67 to 0.94); no significant difference in early bacteriological treatment failure (OR 1.08, 95% CI 0.97 to 1.20) or late clinical recurrence (OR 0.95, 95% CI 0.83 to 1.08). However, the overall risk of late bacteriological recurrence was worse in the short duration treatment studies (OR 1.31, 95% CI 1.16 to 1.48), although no significant differences were found when studies of low dose azithromycin (10 mg/kg) were eliminated (OR 1.06, 95% CI 0.92 to 1.22). Three studies reported long duration complications. Out of 8135 cases of acute GABHS pharyngitis, only six cases in the short duration treatment versus eight in the standard duration treatment developed long-term complications in the form of glomerulonephritis and acute rheumatic fever, with no statistically significant difference (OR 0.53, 95% CI 0.17 to 1.64). AUTHORS' CONCLUSIONS: Three to six days of oral antibiotics had comparable efficacy compared to the standard duration 10-day course of oral penicillin in treating children with acute GABHS pharyngitis. . In areas where the prevalence of rheumatic heart disease is still high, our results must be interpreted with caution.

Short versus standard duration antibiotic therapy for acute streptococcal pharyngitis in children.

BACKGROUND: The standard duration of treatment for acute group A beta hemolytic streptococcus (GABHS) pharyngitis with oral penicillin is 10 days. Shorter duration antibiotics may have comparable efficacy. OBJECTIVES: To summarize the evidence regarding the efficacy of two to six days of newer oral antibiotics (short duration) compared to 10 days of oral penicillin (standard duration) in treating children with acute GABHS pharyngitis. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, issue 4), which contains the Acute Respiratory Infections Group's Specialized Register; the Database of Abstracts of Reviews of Effects (DARE); MEDLINE (1966 to October 2007); OLDMEDLINE (1950 to December 1965); and EMBASE (January 1990 to November 2007). SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing short duration oral antibiotics to standard duration oral penicillin in children aged 1 to 18 years with acute GABHS pharyngitis. DATA COLLECTION AND ANALYSIS: Two review authors scanned the titles and abstracts of retrieved citations and applied the inclusion criteria. We retrieved included studies in full and extracted data. Two review authors independently assessed trial quality. MAIN RESULTS: Twenty studies were included with 13,102 cases of acute GABHS pharyngitis. Compared to standard duration treatment, the short duration treatment had shorter periods of fever (mean difference (MD) -0.30 days, 95% CI -0.45 to -0.14) and throat soreness (MD -0.50 days, 95% CI -0.78 to -0.22); lower risk of early clinical treatment failure (OR 0.80, 95% CI 0.67 to 0.94); no significant difference in early bacteriological treatment failure (OR 1.08, 95% CI 0.97 to 1.20), or late clinical recurrence (OR 0.95, 95% CI 0.83 to 1.08). However, the overall risk of late bacteriological recurrence was worse in the short duration treatment (OR 1.31, 95% CI 1.16 to 1.48), although no significant differences were found when studies of low dose azithromycin (10mg/kg) were eliminated (OR 1.06, 95% CI 0.92 to 1.22). Three studies reported long duration complications with no statistically significant difference (OR 0.53, 95% CI 0.17 to 1.64). AUTHORS' CONCLUSIONS: Three to six days of oral antibiotics had comparable efficacy compared to the standard duration 10 day oral penicillin in treating children with acute GABHS pharyngitis. In countries with low rates of rheumatic fever, it appears safe and efficacious to treat children with acute GABHS pharyngitis with short duration antibiotics. In areas where the prevalence of rheumatic heart disease is still high, our results must be interpreted with caution.

Risk factors of spontaneous pneumothorax in Kuwait.

OBJECTIVES: To determine the risk factors of spontaneous pneumothorax (SP) in Kuwait. SUBJECTS AND METHODS: From January 2002 through December 2003, 254 consecutive cases with a diagnosis of SP were reviewed. Analyses of pneumothorax rates by age, sex, smoking, body mass index (BMI) and climatic conditions were evaluated. RESULTS: Of the 254 patients, 242 (95%) were male and 12 (5%) were female; a larger proportion of 180 (88%) were Kuwaitis and 74 (12%) were expatriates. Two hundred and eight (82%) episodes were regarded as primary SP and 46 (18%) as secondary SP. The mean age was 24.5 +/- 5.8 years for primary SP and 45.7 +/- 14.5 years for secondary SP. One hundred and ninety-six (77%) individuals were current smokers. BMI in primary and secondary SP was 19.3 and 22.4, respectively (p < 0.001). There was no relationship between SP and climatic conditions (a rise or fall in temperature, humidity or atmospheric pressure). However, a slight increase in SP occurred in July, probably the hottest month in Kuwait. CONCLUSIONS: The data indicate that the most important risk factors of SP in Kuwait are smoking, low BMI and the male gender.
