OBJECTIVE To review the 2004 treatment guidelines provided by the American Academy of Pediatrics (AAP) and the American Academy of Family Physicians (AAFP) regarding the treatment of otitis media in pediatric patients. DATA SOURCES A MEDLINE search, restricted to English-language articles about pediatric patients, was conducted (1966–May 2005) using the key words acute otitis media (AOM), guideline, observation therapy, and vaccination. Additional references were located through review of the bibliographies of cited articles. STUDY SELECTION AND DATA EXTRACTION Studies related to the fundamental basis of the updated guidelines and articles addressing current issues related to otitis media infection were included. DATA SYNTHESIS Otitis media affects many children in the US. Concerns have been raised about the proper treatment of AOM in the face of increasing drug resistance among primary pathogens responsible for infection. Some countries have chosen to observe patients for a designated period of time prior to initiation of antibiotic therapy. The AAP and AAFP have updated the treatment guidelines for otitis media to include the option of observation therapy, recommendations for dosing of various antibiotic regimens and their place in therapy, and the importance of initial pain management. CONCLUSIONS Updated treatment guidelines for otitis media have been developed in an effort to properly treat children while decreasing current resistance rates for common organisms that cause AOM. In the future, the therapeutic outcomes of observation therapy related to both the incidence of drug resistance and the possibility of increased complications related to otitis media will need to be evaluated in the US.

Objective To review the epidemiology, pathogenesis, mycology, clinical presentation, and pharmacotherapy of tinea capitis, and describe the role of newer antimycotic agents. Data Sources A MEDLINE search restricted to English-language articles published from 1966 through 1996 and journal references were used in preparing this review. Data Extraction The data on mycology, pharmacokinetics, adverse effects, and drug interactions were obtained from controlled studies and case reports appearing in the literature. Both open-label and comparative studies were evaluated to assess the efficacy of antimycotics in the treatment of this infection. Data Synthesis Griseofulvin is the drug of choice in the treatment of tinea capitis. Newer agents with greater efficacy or shorter treatment durations continue to be explored. Ketoconazole, the first azole studied for efficacy in tinea capitis, has not demonstrated any clinical advantage over griseofulvin in several controlled clinical trials. Itraconazole is effective, but the available data are limited to case reports and a single uncontrolled study. Terbinafine similarly has shown promise in the treatment of tinea capitis, but the oral formulation was only recently approved in the US. Existing studies reflect the results in infection with pathogens not seen in the US. Both itraconazole and terbinafine achieve high concentrations in the hair and stratum corneum that persist for several weeks following drug administration. This may enable shorter courses of therapy; however, comparative studies need to be conducted in the US. Conclusions Tinea capitis remains the most common dermatophyte infection in young urban children. Oral antifungal therapy is required for effective treatment, often for several months. The combination of griseofulvin with a selenium sulfide shampoo continues to be the mainstay of therapy until more experience is gained with the newer antimycotics.

Objective: To investigate the effectiveness of valproate in the prevention of migraine headaches. The drug has been approved by the FDA for migraine prophylaxis in addition to its primary use in seizure control. Data Sources: A MEDLINE search (1988–1995) of the English-language literature pertaining to the use of valproate for prophylaxis of migraine headaches was performed. Additional literature was obtained from reference lists of pertinent articles identified through the search. Study Selection and Data Extraction: All articles were considered for possible inclusion in the review. Pertinent information was selected for discussion. Data Synthesis: Results of five clinical studies carried out worldwide were reviewed: a historical study of 22 patients from Denmark and studies of 32 patients in Israel, 43 patients in Denmark, 75 patients in California, and 117 patients in the US. Eleven patients (50%) were free of headache in the first study. The number of migraine attacks decreased from 15.5 to 8.8 in the second study, whereas patients treated with valproate reported 3.5 days with migraine versus 6.1 for patients receiving placebo in the third study. Efficacy rates of 85% and 61% were seen for patients with frequent migraine and transformed migraine, respectively, in the fourth study, and 48% of patients treated with divalproex compared with 14% of patients receiving placebo showed at least a 50% reduction in migraine headache frequency in the fifth study. Conclusions: Approximately half of the patients were shown to experience roughly a 50% reduction in the number of migraine attacks or days with migraine headaches; thus, valproate appears to provide a therapeutic alternative for patients who do not respond to or cannot tolerate beta-receptor blockers, tricyclic antidepressants, or calcium-channel blockers for prophylaxis of migraine headaches.

OBJECTIVE: To reconcile conflicting reports of antibiotic efficacy for otitis media with effusion in children. DATA SOURCES: English-language MEDLINE search (“antibiotics” and “otitis” media with effusion“) from January 1980 through December 1990. Current Contents 1990, consultation with experts, and references from review articles, textbook chapters, and retrieved reports. STUDY SELECTION: Randomized clinical trials with concurrent controls (placebo or no drug), and children with at least one ear not violated by tympanocentesis. Ten of the initial 82 articles were selected after blind review of the methods sections. DATA EXTRACTION: We independently evaluated each trial using 20 measures of internal and external validity, then extracted treatment and control responses for an end point of all affected ears free of effusion at the first posttreatment assessment. DATA SYNTHESIS: Pooled analysis of 1325 children yielded a rate difference of 22.8% (95% CI, 10.5 to 35.1) that was minimally affected by interstudy quality differences, and was unlikely to represent publication bias. Variations in trial outcomes were not attributable to chance, study design, or choice of drug, but were inversely related to the control group natural cure rate. Children with chronic bilateral effusions not related to a recent episode of acute otitis media tended to have lower natural cure rates, and a more favorable response to therapy. CONCLUSIONS: Antibiotics have a clinically and statistically significant impact on the resolution of otitis media with effusion. The association between outcome and natural cure rate has important implications for the design and interpretation of future trials.

OBJECTIVE: To review new pharmacologic agents approved for use in the management of rheumatoid arthritis (RA). DATA SOURCES: A MEDLINE search (1966–January 2000) was conducted to identify English-language literature available on the pharmacotherapy of RA, focusing on celecoxib, leflunomide, etanercept, and infliximab. These articles, relevant abstracts, and data provided by the manufacturers were used to collect pertinent data. STUDY SELECTION: All controlled and uncontrolled trials were reviewed. DATA EXTRACTION: Agents were reviewed with regard to mechanism of action, efficacy, drug interactions, pharmacokinetics, dosing, precautions/contraindications, adverse effects, and cost. DATA SYNTHESIS: Traditional pharmacologic treatments for RA have been limited by toxicity, loss of efficacy, or both. Increasing discoveries into the mechanisms of inflammation in RA have led to the development of new agents in hopes of addressing these limitations. With the development of celecoxib, a selective cyclooxygenase-2 inhibitor, the potential exists to minimize the gastrotoxicity associated with nonsteroidal antiinflammatory drugs. Leflunomide has been shown to be equal to or less efficacious than methotrexate, and may be beneficial as a second-line disease-modifying antirheumatic drug (DMARD). The biologic response modifiers, etanercept and infliximab, are alternatives that have shown benefit alone or in combination with methotrexate. However, they should be reserved for patients who fail to respond to DMARD therapy. Further studies should be conducted to evaluate the long-term safety and efficacy of these agents as well as their role in combination therapy. CONCLUSIONS: Celecoxib, leflunomide, etanercept, and infliximab are the newest agents approved for RA. Clinical trials have shown that these agents are beneficial in the treatment of RA; however, long-term safety and efficacy data are lacking.

OBJECTIVE: To familiarize readers with a potentially new class of compounds for treating asthma. Background information on leukotrienes is provided in addition to an indepth review of pertinent clinical trials. DATA SOURCES: Information was obtained from controlled clinical trials, abstracts, and review articles identified through a MEDLINE search of English-language articles. STUDY SELECTION: Emphasis was placed on early clinical trials that showed some benefit with these compounds as well as more recent studies using newer agents that produced more promising results. DATA EXTRACTION: Information regarding leukotriene biochemistry was extracted from basic science research and data from human studies were evaluated by the authors according to patient selection, study design, methodology, and therapeutic response. DATA SYNTHESIS: Leukotrienes have a pathophysiologic role in asthma. Two distinct but pharmacologically similar classes of leukotriene inhibitors are currently being clinically evaluated. These are leukotriene receptor antagonists and 5-lipoxygenase inhibitors. Early clinical trials with these agents yielded unfavorable results primarily because of lack of drug potency and selectivity, poor patient tolerance, and possibly the route of administration. Subsequent studies with more potent and selective agents have further implicated leukotrienes as biochemical mediators in asthma and, consequently, have shown promising clinical outcomes with respect to pulmonary function testing and patient tolerance. CONCLUSIONS: Advancements in the pathogenesis of asthma are beginning to define a role for the leukotrienes. Although more studies are needed to assess the efficacy of leukotriene inhibitors, recent clinical trials using leukotriene-receptor antagonists and 5-lipoxygenase inhibitors indicate a potential for the expansion of therapeutic regimens currently used in the treatment of asthma.

OBJECTIVE: To review the literature and provide recommendations for the development and dissemination of written medication information to patients and their care providers. DATA SOURCES: A MEDLINE search (1966–1997) of the English-language literature was performed to identify articles pertaining to the development or use of written medication information. A search of the Internet was conducted by using Yahoo as the guide and “medication information” as the search term. Additional resources were obtained through texts, bibliographies, and catalogs from medical publishers. DATA EXTRACTION: Reports documenting the creation and use of written medication information systems were reviewed, as well as studies of readability and reading skills assessment. Examples of materials available for purchase by laypeople and healthcare providers were also examined. DATA SYNTHESIS: Current statistics support the widespread availability of written medication information for patients and care providers. The goal set forth by the Food and Drug Administration of having 75% of patients receive written information by the year 2000 appears achievable. However, there are still many issues to address. Content is not standardized, and materials are frequently written at reading levels higher than that of the average patient. The development and use of resources requiring only minimal reading skills and an increase in the availability of materials written in Spanish are needed. CONCLUSIONS: Written medication information provides a useful addition to counseling by healthcare professionals. A wide variety of prepared materials is available, as well as resources for those interested in developing tools for a specific patient, population, or setting. Healthcare professionals should be aware of the limitations of some resources. Content and readability must be appropriate for the intended audience for these tools to serve a useful role in patient education.

Abstract Objectives.—To review the literature for conditions, diseases, and disorders that affect activity of the contact factors, and further to review the literature for evidence that less than normal activity of any of the contact factors may be associated with thrombophilia. Data Sources.—MEDLINE search for English-language articles published from 1988 to 2001 and pertinent references contained therein, as well as search of references in recent relevant articles and reviews. Study Selection.—Relevant clinical and laboratory information was extracted from selected articles. Meta-analysis was not feasible because of heterogeneity of reports. Data Extraction and Synthesis.—Evidence for association of altered levels of the contact factors and thrombophilia was sought. A wide variety of disorders is associated with decreased activity of the contact factors; chief among these disorders are liver disease, hepatic immaturity of newborns, the antiphospholipid syndrome, and, for factor XII, being of Asian descent. These disorders are more common than homozygous deficiency. The few series and case reports of thrombophilic events in patients homozygous for deficiency of contact factors are not persuasive enough to support causality. The apparent association between levels consistent with heterozygosity (40%–60% of normal) of any of the contact factors (but especially factor XII) in persons with antiphospholipid antibodies appears to be due to falsely decreased in vitro activity levels of these factors, which are normal on antigenic testing. The apparent association with thrombosis is better explained by the antiphospholipid syndrome than by the modest reduction of the levels of contact factors. Conclusions.—Presently, it is not recommended to measure activity of contact factors during routine evaluation of patients who have suffered venous or arterial thromboembolism or acute coronary syndromes.

Objective To describe a case of isoniazid-associated psychosis and review the incidence of this adverse effect. Data Sources Information about the patient was obtained from the medical chart. A MEDLINE search of the English-language literature published from 1950 to 1992 was conducted and Index Medicus was manually searched for current information. Study Selection All case reports describing isoniazid-associated psychosis were reviewed. Data Extraction Studies were evaluated for the use of isoniazid, symptoms of psychosis, onset of symptoms, and dosage of isoniazid. Data Synthesis The case report is compared with others reported in the literature. The incidence of isoniazid-associated psychosis is rare. Conclusions The mechanism of isoniazid-associated psychosis is uncertain. It appears that isoniazid was associated with the psychosis evident in our patient and in the cases reviewed.

Therapeutic Equivalency

OBJECTIVE: To review the recent literature on the approved uses of enoxaparin, dalteparin, ardeparin, and tinzaparin and the evidence for therapeutic equivalence. DATA SOURCES: A MEDLINE search (1993–January 2001) was conducted to identify English-language literature available on enoxaparin, dalteparin, ardeparin, and tinzaparin. STUDY SELECTION: All controlled trials evaluating low-molecular-weight heparins (LMWHs) versus standard therapy powered to detect a significant difference were reviewed. DATA EXTRACTION: Agents were reviewed with regard to safety and efficacy. DATA SYNTHESIS: As a class, LMWHs have chemical, physical, and clinical similarities. LMWHs have greater bioavailability, longer half-lives, a more predictable pharmacologic response, possible improved safety, and similar or greater efficacy compared with unfractionated heparin (UFH). Because of this, enoxaparin, dalteparin, ardeparin, and tinzaparin are being considered as alternatives to UFH or warfarin, and there is potential for therapeutic interchange. Evaluation of clinical trials is limited because of differing diagnostic methods, drug administration times, dose equivalencies, and outcome measurements. CONCLUSIONS: Only 1 trial has evaluated 2 LMWHs in a direct comparison in the same study. There is insufficient evidence for determining the therapeutic equivalence of LMWHs.
