Recently, new evidence-based recommendations have been introduced for diagnosing and managing otitis media with effusion (OME) in children. However, there are some difficulties to follow the general guidelines in the tertiary hospitals. The purpose is to evaluate the efficiency of antibiotics or antihistamines for treatment of children with OME in the tertiary hospital with a randomized prospective clinical study.
                Eighty-four children with OME who had been diagnosed in the tertiary hospital were randomized to receive 5 different medications for 2 weeks. We prescribed antibiotics (amoxicillin-clavulanate syrup) in Group I (n=16), antibiotics/steroids (prednisolone) in Group II (n=18), antibiotics/antihistamines (ebastine) in Group III (n=15), antibiotics/steroids/antihistamines in Group IV (n=17), and mucolytics (ivy leaf extract) in Group V (n=17) for control. We followed-up children every 2 weeks and evaluated the state of OME at 3 months.
                Thirty six (42.9%) of 84 children were resolved within average 6.9 weeks after the treatments. Thirty-six (42.9%) were treated with ventilation tube insertion and 12 patients (14.3%) were observed. There was no difference in the resolution rates of OME among the five different protocols (P>0.05). There was no difference in the resolution rates among groups who used steroids, antihistamines, steroids and antihistamines, or other medications to manage 42 children with allergies (P>0.05).
                In the tertiary hospital, the cure rate of children with OME was not as high as well-known, and antibiotics or anti-allergic medications were not more effective than control. We may, therefore, need any other guidelines which are different from the previous evidence-based recommendations, including early operation in the tertiary hospitals. A controlled clinical trial in children with acute infections of the lower respiratory tract was carried out to see whether or not treatment with ambroxol could bring about faster and better results. One hundred twenty children with acute lower respiratory tract infections were all given antibiotics plus, at random, either ambroxol (1.5-2.0 mg/kg body weight orally) or a placebo. The duration of the trial was ten days. All the patients in both groups were cured clinically. However, remission of the cough, of the chest pathological signs, as well as the improvement of the lung radiographical pictures were significantly more rapid in children treated with ambroxol than in those who received the antibiotic alone. Ambroxol was tolerated perfectly by all the children. To ascertain that antibiotics have no role in the management of bronchiolitis.
                Multicentre randomized control trial (RCT).
                Five purposively selected teaching hospitals in Bangladesh.
                Children under 24 months old with bronchiolitis.
                Children were randomized into three groups of therapeutic interventions: parenteral ampicillin (P-Ab), oral erythromycin (O-Ab) and no antibiotic (N-Ab) in adjunct to supportive measures.
                Clinical improvement was assessed using 18 symptoms/signs which were graded on a two-point recovery scale of 'rapid' and 'gradual', indicating improvement within 'four days' and 'beyond four days', respectively.
                Each intervention group consisted of 98 +/- 1 children having comparable clinico-epidemiological characteristics at the baseline. The trial revealed that most chesty features (features appearing to arise from chest, i.e. cough, breathing difficulty, wheeze, chest indrawing, tachypnoea, tachycardia, rhonchi and crepitation) demonstrated a gradual recovery, beyond 4th admission day and, not differing among the three intervention groups (p > 0.23, p < 0.62, p = 0.54, p < 0.27, p = 0.75, p = 0.76, p = 0.81, p > 0.98, respectively). Most non-chesty features (features appearing to arise away from chest, i.e. feeding/sleeping difficulties, social smile, restlessness, inconsolable crying, nasal flaring, fever and hypoxaemia) demonstrated a rapid recovery, within 4 days, remaining comparable among the three intervention groups (p < 0.07, p = 0.65, p = 0.24, p < 0.61, p = 0.22, p = 0.84, p = 0.29 and p = 0.96, respectively). However, nasal symptoms (runny nose and nasal blockage) also showed no difference among groups (p = 0.36 and p = 0.66, respectively). Thus, the dynamics of clinical outcome obviates that children not receiving antibiotics had similar clinical outcome than those who did.
                In hospital settings, managing bronchiolitis with only supportive measures but without antibiotics remains preferable. The purpose of the meta-analysis was to understand the antitussive effect of treatment with dextromethorphan hydrobromide, 30 mg, vs placebo over a 3-h treatment period in patients with cough due to uncomplicated upper respiratory tract infection (URTI), and to show that the computerized system for acquisition and analysis of cough sound was consistent and reproducible across the individual studies.
                The six studies used for the meta-analysis were randomized, double-blind, parallel-group, single-dose, placebo-controlled studies with a 3-h postdose cough evaluation period.
                One study was conducted in Durban, South Africa, and five studies were conducted in Bombay, India. Four studies took place in clinics, and two studies were in-home studies.
                Seven hundred ten adult patients with cough due to uncomplicated URTI who were otherwise healthy and who satisfied the inclusion/exclusion criteria for the meta-analysis. Measurements and results: For each patient, a standard baseline was calculated pretreatment, then a 3-h continuous cough recording was made after treatment was initiated. Five efficacy variables were measured in 30-min intervals: cough bouts, cough components, cough effort, cough intensity, and cough latency. The meta-analysis showed consistent results across most of the studies for each of the efficacy variables. It demonstrated significantly greater overall reductions in cough bouts, cough components, and cough effort, and an increase in cough latency for patients treated with dextromethorphan hydrobromide, 30 mg, vs those treated with placebo.
                The results of a meta-analysis of the six clinical studies show that the antitussive effect of a single dose of dextromethorphan hydrobromide, 30 mg, has been established. The consistent nature of the results shows that the computerized cough acquisition and analysis system is a valid and reproducible methodology for evaluating cough associated with URTI. 52 children with severe cough persisting for more than 10 days were randomized to treatment with amoxycillin/clavulanic acid or placebo in a prospective double-blinded study. Clinically suspected cases of pertussis were excluded, yet 12 (23%) of the children had laboratory verified pertussis infection. The nasopharyngeal colonization showed a predominance of Moraxella catarrhalis which was isolated in 37 (71%) children. Streptococcus pneumoniae and Haemophilus influenzae were isolated in 11 (20%) and 16 (30%) children, respectively. The antibiotic-treated group had a significantly better recovery in both the pediatrician's estimation (p = 0.02) and the independent parental judgement (p = 0.002). These findings are consistent with the view that Moraxella catarrhalis could be directly involved in the pathogenesis of persistent cough in children. To assess the effect of a tailored professional intervention, including academic detailing, on antibiotic prescribing for acute cough.
                In a cluster-randomized controlled before and after study 85 Flemish GPs included adult patients with acute cough consulting in the periods February-April 2000 and 2001. The intervention consisted of a clinical practice guideline for acute cough, an educational outreach visit and a postal reminder to support its implementation in January 2001. Antibiotic prescribing rates and patients' symptom resolution were the main outcome measures.
                Thirty-six of 42 GPs received the intervention and 35 of 43 GPs served as controls; 1503 patients were eligible for analysis. Only in the intervention group were patients less likely to receive antibiotics after the intervention [OR(adj) (95% CI)=0.56 (0.36-0.87)]. Prescribed antibiotics were also more in line with the guideline in the intervention group [1.90 (0.96-3.75)] and less expensive from the perspective of the National Sickness and Invalidity Insurance Institute [MD(adj) (95% CI)= Euro -6.89 [-11.77-(-2.02)]]. No significant differences were found between the groups for the time to symptom resolution.
                An (inter)actively delivered tailored intervention implementing a guideline for acute cough is successful in optimizing antibiotic prescribing without affecting patients' symptom resolution. Further research efforts should be devoted to cost-effectiveness studies of such interventions. To test the hypothesis that inhaled salbutamol or beclomethasone will reduce the frequency of cough in children with recurrent cough. A secondary aim was to determine if the presence of airway hyperresponsiveness (AHR) can predict the response.
                Randomised, double blind, placebo controlled trial.
                During a coughing phase, 43 children (age 6-17 years) with recurrent cough were randomised to receive inhaled salbutamol or placebo (phase I) for 5-7 days and then beclomethasone or placebo (phase II) for 4-5 weeks, and in a subgroup of children for 8-9 weeks. The children used an ambulatory cough meter, kept cough diaries, and performed the capsaicin cough sensitivity, hypertonic saline bronchoprovocation, and skin prick tests.
                Salbutamol or beclomethasone had no effect on cough frequency or score, irrespective of the presence of AHR.
                Most children with recurrent cough without other evidence of airway obstruction, do not have asthma and neither inhaled salbutamol nor beclomethasone is beneficial. The diagnosis and the treatment of community-acquired severe pneumonia is still a serious child health problem in developing countries. The aim of this study is to evaluate the effectiveness of two different antibiotic regimens in the empirical treatment of severe childhood pneumonia.
                We enrolled 97 infants (aged 2-24 months) with severe community-acquired pneumonia in a randomized-controlled trial of 10 days of treatment with penicillin G+chloramphenicol (n:46) or ceftriaxone (n:51). We evaluated the effectiveness of treatments with symptoms and some laboratory tests during and at the end of the study.
                The cure rates were similar in both groups and the antibiotic regimens in all patients were found effective (P< 0.001). The number of nurse rounds was much more in penicillin plus chloramphenicol group than ceftriaxone group.
                Both penicillin G plus chloramphenicol and ceftriaxone are effective in the empirical treatment of severe community pneumonia of young children. In spite of more nurse visits for antibiotic treatment, penicillin G+ chloramphenicol combination may be a cheaper alternative to ceftriaxone in the treatment of childhood pneumonia. The benefits of antibiotic treatment and a nasopharyngeal culture in children with longstanding cough were analysed in a prospective randomized open study. Clinically suspected pertussis was excluded. Of 40 children given erythromycin for 7 days, 35 (88%) recovered in one week, compared with 17/47 (36%) untreated (p < 0.0001). Erythromycin eliminated Moraxella catarrhalis from the nasopharynx in 21/31 children (68%), compared with spontaneous disappearance in 7/35 (20%) untreated controls (p < 0.001). Purulent bronchitis or otitis media occurred in 2 children (5%) in the treatment group and in 21 (45%) in the control group (p < 0.01). To evaluate the clinical role of isolated pathogens, the 47 untreated subjects were studied. Seven of 35 children harbouring M. catarrhalis recovered, compared with 8/12 in whom this bacterium was absent (p < 0.01). No correlation was found between the isolation of Haemophilus influenzae or Streptococcus pneumoniae and the clinical outcome. Children with persistent cough > 10 days may benefit from erythromycin treatment. M. catarrhalis in the nasopharynx indicates prolonged symptoms and increased risk of bacterial complications.
Antibiotics are likely to be beneficial in the treatment of children with chronic moist cough. This evidence is however limited by study quality, study design and sensitivity analysis data. The use of antibiotics however has to be balanced against their well known adverse events. Further well-designed RCTs using valid cough outcome measures are needed to answer this question conclusively.
