Rhinosinusitis in children.

Clinical practice guidelines for the management of acute bacterial rhinosinusitis in children were published by the American Academy of Pediatrics in 2001. Changes in the antibiotic susceptibility patterns for the common pathogens causing both acute and chronic rhinosinusitis warrant a reevaluation and update of these recommendations. In addition, there was only a very brief discussion of chronic disease in this publication, with the conclusion that the pathogenesis and management of recurrent or prolonged infection were essentially unknown. Although there are still insufficient data in the literature to develop evidence-based clinical guidelines, a careful review of recent literature and the clinical experience of experts who manage pediatric chronic sinusitis are presented in an effort to provide some specific recommendations and to offer practical treatment options. Factors associated with chronic rhinosinusitis should be addressed individually and include environmental pollution, recurrent viral upper respiratory infections, allergic and nonallergic rhinitis, ciliary dyskinesia, cystic fibrosis, immunodeficiency, gastroesophageal reflux, and anatomic abnormalities.

Adherence issues related to the selection of antistaphylococcal or antifungal antibiotic suspensions for children.

To evaluate the palatability and cost as variables in the selection of antimicrobial suspensions to treat staphylococcal infections and oral thrush, 31 physicians and health care personnel randomly sampled 7 antistaphylococcal antibiotics and 2 antifungal agents, evaluating them in categories of appearance, smell, texture, taste, and aftertaste. Final scoring was then adjusted for cost. Overall taste (palatability) ranking of antistaphylococcal antibiotics, highest to lowest, was as follows: rifampin, cephalexin, EES, TMP/SMX, clindamycin with FLAVORx, linezolid, and clindamycin without FLAVORx. Fluconazole was superior to nystatin. Cost was considered a major factor if the medication was more than $60.00 for treatment of a hypothetical 2-year-old, 13-kg child.

Pertussis is eradication achievable?

We are now on the threshold of a major step in reducing the incidence of pertussis and its associated mortality and morbidity in young children. Assuring that vaccines are received in a timely fashion by all children and correcting the "missed opportunities" for providing this highly effective intervention are most critical. A plan for booster immunizations must be developed for older children and adults to offer further protection of young infants through the cocoon effect that this would create for them.

Health services for homeless adolescents.

This prospective review was designed to determine the effectiveness of a broad-spectrum health intervention program for homeless and runaway youth. Diagnosis, treatment, and counseling for drug use, sexually transmitted diseases (STDs), and other health issues were provided to all new admissions to a residential care facility during a 7(1/2)-year enrollment. Education was continued during a minimum follow-up period of 9 months based on the program entitled Bright Futures, previously developed and published by the National Center for Education in Maternal and Child Health. Fifty-four percent of the study residents had STDs on admission, and 9% developed new STDs after completing therapy and undergoing counseling. Drug dependence was reduced from 47% to 4%, and 46% achieved full-time or part-time employment. Sixty-three percent completed hepatitis B immunization with the 3-dose series. This experience suggests that an organized program of interventions in a residential care facility for homeless teenagers can significantly reduce drug dependence and STDs.

Culture-negative osteomyelitis.

OBJECTIVE: To examine the natural history, clinical manifestations, laboratory changes and outcomes of children with culture-negative osteomyelitis and to compare findings with cases of culture-positive infection treated during the same time period. DESIGN: Retrospective review of consecutive admissions for osteomyelitis during the 4-year period 1998 through 2001, with a minimum follow-up of 1 year. SETTING: A single urban children's hospital with a large orthopedic referral service. CLINICAL AND LABORATORY MEASURES: Age, gender, predisposing factors, clinical manifestations, maximum temperature, duration of pain, bone involved, laboratory changes, results of cultures from infected bone and blood and outcome after treatment. RESULTS: A total of 85 patients fulfilled study criteria, of whom 40 were culture-negative. Compared with culture-positive cases, culture-negative osteomyelitis patients were less likely to have antecedent trauma (P = 0.0357) and overlying skin changes (P = 0.0001), duration of pain and other symptoms was longer (P = 0.0396) and skeletal residua were rare. They were also older, with this difference approaching statistical significance (P = 0.0586). CONCLUSIONS: Children with culture-negative osteomyelitis present initially differently from culture-positive cases and can be managed as presumed staphylococcal disease with excellent long term results.

Patient, physician, and nurse satisfaction with antibiotics.

To prospectively evaluate patient (parent), physician, and nurse satisfaction with antibiotics, 12,102 children in 661 pediatric study centers throughout the United States with infections to be treated on an outpatient basis were followed with questionnaires completed by parents and with interviews of patients and their parents. Comprehensive surveys were also completed by participating pediatricians and their nursing staffs of which 11,913 (98.4%) contained adequate information for inclusion in an analysis. Data were combined and analyzed using standard statistical methods. Loracarbef was perceived as being superior to other antibiotics based on cost, palatability, and dosing intervals. Few differences were seen among most antibiotics based on treatment outcome or adverse events. All antibiotics studied offered acceptable efficacy and were well tolerated as judged by physicians, nurses, parents, and children. Slight differences might result in increased compliance for some patients.

Chronic sinusitis in children.

Clinical practice guidelines for the management of acute sinusitis in children have been published by the American Academy of Pediatrics. Of note is that in this document, a brief discussion of chronic disease concluded that the pathogenesis and management are essentially unknown. Although there are insufficient data in the literature to develop evidence-based clinical guidelines, a careful review of the literature and clinical experience of experts who manage pediatric chronic sinusitis is presented in an effort to develop specific recommendations and to offer practical treatment options. Factors associated with chronic sinusitis should be addressed individually and include recurrent viral upper respiratory infections, allergic and nonallergic rhinitis, ciliary dyskinesia, cystic fibrosis, immunodeficiency, and anatomic abnormalities. Bacteriology includes the 3 pathogens associated with acute disease i.e., Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis but with chronic sinusitis also includes Staphylococcus aureus, anaerobic bacteria, and fungi. Medical interventions discussed include endoscopic sinus surgery, saline nasal irrigation, intranasal decongestant therapy, intranasal steroids, and oral antibiotics. Clinical ranking without regard to side effects and cost suggests that endoscopic sinus surgery and antral irrigation have the highest probability of substantial symptom improvement. Other issues discussed include identification and management of gastroesophageal reflux disease (GERD), allergy, and immune deficiency.

Nasopharyngeal carriage and susceptibility patterns of Streptococcus pneumoniae in Kumasi, Ghana.

UNLABELLED: Penicillin resistant Streptococcus pneunmoniae poses an increasing problem in paediatrics, particularly in less developed countries. Outside of South Africa, little is known about S. pneumoniae susceptibilities in Sub-Saharan Africa. The objective of this study was to determine the prevalence of pneumococcal colonization and antimicrobial susceptibility among children in urban Ghana. METHODS: Nasopharyngeal pneumococcal colonization was examined in 311 children attending a polyclinic for sick children and an immunization clinic in Kumasi, Ghana. Isolates were tested for antibiotic susceptibility to penicillin, tetracycline, erythromycin, chloramphenicol, cefuroxime, cefotaxime, ceftriaxone, and trimethoprim-sulfamethoxazole. RESULTS: Over half (51.4%) of subjects were colonized with S. pneumoniae and 17% of isolates were resistant to penicillin, all demonstrating intermediate resistance. S. pneumoniae strains were also frequently resistant to trimethoprim-sulfamethoxazole and tetracycline, less so to chloramphenicol and cefuroxime and were almost uniformly sensitive to cefotaxime, cefriaxone and erythromycin. CONCLUSIONS: Our study shows a high rate of pneumococcal nasopharyngeal colonization and a concerning level of penicillin resistance although at a less alarming rate than seen in some other countries. Multiple antimicrobial resistance was also noted especially among drugs readily available and commonly used. These data impact treatment choices in pneumococcal disease. Vaccine may play an important role in disease limitation. An effort to curtail the misuse of antibiotics, by prescription and otherwise, may prevent further increases in resistance rates.
