The treatment of fractures in children and adolescents must be based on an adequate knowledge of the physiology of the growing skeleton. Treatment failures usually do not result from technical deficiencies, but rather from a misunderstanding of the special considerations applying to the treatment of fractures in this age group. ⋯ The main requirements for the proper treatment of fractures in children and adolescents are the immediate alleviation of pain and the provision of effective treatment (either in the hospital or on an outpatient basis) to ensure the best possible outcome, while the associated costs and effort is kept to a minimum. Further important goals are a rapid recovery of mobility and the avoidance of late complications, such as restriction of the range of motion or growth disorders of the fractured bone. To achieve these goals, the treating physician should have the necessary expertise in all of the applicable conservative and surgical treatment methods and should be able to apply them for the proper indications.

Primary brain tumors are among the ten most common causes of cancer-related death. There is no screening test for them, but timely diagnosis and treatment improve the outcome. Ideally, treatment should be provided in a highly specialized center, but patients reach such centers only on the referral of their primary care physicians or other medical specialists from a wide variety of fields. An up-to-date account of basic knowledge in this area would thus seem desirable, as recent years have seen major developments both in the scientific understanding of these tumors and in clinical methods of diagnosis and treatment. ⋯ Modern neuroradiological imaging, in particular magnetic resonance imaging, can show structural lesions at high resolution and provide a variety of biological and functional information, yet it is still no substitute for histological diagnosis. Gross total resection of gliomas significantly improves overall survival. New molecular markers can be used for prognostication. Chemotherapy plays a major role in the treatment of various different kinds of glioma. The median survival, however, generally remains poor, e.g., 14.6 months for glio-blastoma.

Hypothyroidism and hypocalcemia are common after thyroid and parathyroid surgery. In this article, the authors provide clinically-oriented recommendations to help surgeons, general practitioners, internists, and endocrinologists give their affected patients adequate hormone replacement therapy. ⋯ Effective treatment requires an appropriate choice of medication and an understanding of its pharmacokinetics as well as of the possible effects of the patient's underlying disease, comorbidities, and other medications on its absorption and metabolism.

Regression analysis is an important statistical method for the analysis of medical data. It enables the identification and characterization of relationships among multiple factors. It also enables the identification of prognostically relevant risk factors and the calculation of risk scores for individual prognostication. ⋯ The performance and interpretation of linear regression analysis are subject to a variety of pitfalls, which are discussed here in detail. The reader is made aware of common errors of interpretation through practical examples. Both the opportunities for applying linear regression analysis and its limitations are presented.

Review Meta Analysis
Midclavicular fracture: not just a trivial injury: current treatment options.
Conservative treatment was long recommended for midclavicular fractures because of the excellent results that were reported in the 1960's and 70's. Recently, however, the rucksack bandage has received competition from surgical treatment. The spectrum of operations ranges from classic plate osteosynthesis to intramedullary techniques and angle-stable implants. ⋯ In any case of midclavicular fracture, the type of fracture should be precisely analyzed and an individual treatment strategy should be developed in view of the patient's particular situation. Current studies show with a high level of evidence (level 1) that patients with dislocated fractures benefit from surgery.
