Specific immunotherapy (SIT) in the treatment of allergic rhinitis.
Allergic rhinitis (AR) exhibits a prevalence of approx. 20% in Germany and causes enormous costs in the health care system. Specific immunotherapy (SIT) is considered to be the only potentially causal therapy for AR and mainly administered by two routes, subcutaneous (SCIT) and sublinguale (SLIT). SIT promises a reduction of symptoms and the need for medication in patients with AR. ⋯ The effectiveness of SIT in patients with AR is not equally proven for all SIT administration forms and allergens. For SCIT and SLIT with grass pollen allergens short and medium-term effectiveness can be regarded as proven. These therapy forms should be used if the indication is appropriate and if no contraindications are present. Also SCIT and SLIT with other seasonal allergens such as tree pollen allergens can be an effective treatment option, but used with a certain restraint due to insufficient data especially in the case of SLIT. For SIT with house dust mite allergens and further perennial allergens no consistent proof of effectiveness are to be determined from the available information. Further research addressing non-grass pollen-associated SIT, allergen and manufacturer specific evaluations as well as asthma prevention is needed. Due to the lack of evidence the use of SIT can not be seen proven as cost effective. To provide such evidence further health economic studies with a long term follow-up are needed. The informed consent of the patients is an important ethical requirement within the use of SIT.

Outpatient pulmonary rehabilitation - rehabilitation models and shortcomings in outpatient aftercare.
The chronic obstructive pulmonary disease (COPD) and the bronchial asthma are widespread diseases. They need long-lasting and sustainable rehabilitation. ⋯ Out-patient pulmonary rehabilitation is as effective as in-patient pulmonary rehabilitation. But there is a critical shortage of out-patient pulmonary rehabilitation supply in Germany. Domains for further research are the evaluation of models for integrated care, the length, frequency and content of training programmes, psychiatric assessments and the cost-effectiveness of out-patient pulmonary rehabilitation.

Comparison of tools for assessing the methodological quality of primary and secondary studies in health technology assessment reports in Germany.
HEALTH CARE POLICY BACKGROUND: Findings from scientific studies form the basis for evidence-based health policy decisions. ⋯ There are different, design-specific tools available which can be preferred for quality assessment, because of its wider coverage of substantive elements of internal validity. To minimise the subjectivity of the assessment, tools with a detailed and precise operationalisation of the individual elements should be applied. For health economic studies, tools should be developed and complemented with instructions, which define the appropriateness of the criteria. Further research is needed to identify study characteristics that influence the internal validity of studies.

Effectiveness of pharmaceutical therapy of ADHD (Attention-Deficit/Hyperactivity Disorder) in adults - health technology assessment.
Attention-Deficit/Hyperactivity Disorder (ADHD) is a mental disorder. Symptoms include hyperactivity, lack of attentiveness, and frivolousness. This disorder always begins in childhood, but can remain through adulthood. ADHD affects all areas of life and limits the quality of life due to its symptoms and the high rate of associated disorders that can develop. An established form of therapy is using stimulant medications, most commonly, containing Methylphenidate as the active ingredient. However, in Germany this ingredient is not approved for adults suffering from ADHD. Therefore, many adults cannot obtain appropriate medication to treat this disorder. ⋯ Medical treatment, particularly including Methylphenidate and Atomoxetine, proves to have a positive effect. In order to attain an optimal drug response, dosing must be determined on an individual basis. There is a need of high-quality studies that directly compare various agents - an aspect which is relevant to medical effectiveness of a therapy. No definite statement can be made about the cost-effectiveness of the medical treatment of ADHD in adults. More health economic studies are therefore required. Apart from the unquestionable mental indication, it is already recommended by health economic reasons to establish the conditions for an adequate treatment with these medicaments also for adults.

The importance of growth factors for the treatment of chronic wounds in the case of diabetic foot ulcers.
Ulcers as a result of diabetes mellitus are a serious problem with an enormous impact on the overall global disease burden due to the increasing prevalence of diabetes. Because of long hospital stays, rehabilitation, often required home care and the use of social services diabetic foot complications are costly. Therapy with growth factors could be an effective and innovative add-on to standard wound care. ⋯ There are indications of an advantage for the add-on therapy with growth factors in diabetic foot ulcers concerning complete wound closure and the time to complete wound healing. Further more studies of high methodological quality with adequate sample sizes and sufficient follow-up periods are necessary also investigating patient-relevant parameters like the health-related quality of life, the acceptance and tolerance of the intervention in addition to clinical outcomes.
