Minimally invasive surgical procedures for the treatment of lumbar disc herniation.
In up to 30% of patients undergoing lumbar disc surgery for herniated or protruded discs outcomes are judged unfavourable. Over the last decades this problem has stimulated the development of a number of minimally-invasive operative procedures. The aim is to relieve pressure from compromised nerve roots by mechanically removing, dissolving or evaporating disc material while leaving bony structures and surrounding tissues as intact as possible. In Germany, there is hardly any utilisation data for these new procedures - data files from the statutory health insurances demonstrate that about 5% of all lumbar disc surgeries are performed using minimally-invasive techniques. Their real proportion is thought to be much higher because many procedures are offered by private hospitals and surgeries and are paid by private health insurers or patients themselves. So far no comprehensive assessment comparing efficacy, safety, effectiveness and cost-effectiveness of minimally-invasive lumbar disc surgery to standard procedures (microdiscectomy, open discectomy) which could serve as a basis for coverage decisions, has been published in Germany. ⋯ Conclusions that can be drawn from the results of the present assessment refer in detail to the specified minimally-invasive procedures of lumbar disc surgery but they may also be considered exemplary for other fields where optimisation of results is attempted by technological development and widening of indications (e.g. total hip replacement). Compared to standard technologies (open discectomy, microdiscectomy) and with the exception of chemonucleolysis, the developmental status of all other minimally-invasive procedures assessed must be termed experimental. To date there is no dependable evidence-base to recommend their use in routine clinical practice. To create such a dependable evidence-base further research in two directions is needed: a) The studies need to include adequate patient populations, use realistic controls (e.g. standard operative procedures or continued conservative care) and use standardised measurements of meaningful outcomes after adequate periods of time. b) Studies that are able to report effectiveness of the procedures under everyday practice conditions and furthermore have the potential to detect rare adverse effects are needed. In Sweden this type of data is yielded by national quality registries. On the one hand their data are used for quality improvement measures and on the other hand they allow comprehensive scientific evaluations. Since the year of 2000 a continuous rise in utilisation of minimally-invasive lumbar disc surgery is observed among statutory health insurers. Examples from other areas of innovative surgical technologies (e.g. robot assisted total hip replacement) indicate that the rise will probably continue - especially because there are no legal barriers to hinder introduction of innovative treatments into routine hospital care. Upon request by payers or providers the "Gemeinsamer Bundesausschuss" may assess a treatments benefit, its necessity and cost-effectiveness as a prerequisite for coverage by the statutory health insurance. In the case of minimally-invasive disc surgery it would be advisable to examine the legal framework for covering procedures only if they are provided under evaluation conditions. While in Germany coverage under evaluation conditions is established practice in ambulatory health care only ("Modellvorhaben") examples from other European countries (Great Britain, Switzerland) demonstrate that it is also feasible for hospital based interventions.

Cerebrovascular disorders are an important cause of mortality and chronic morbidity in children. Ischemic stroke is more common than cerebral venous thrombosis and hemorrhagic stroke in children. Several medical disorders have been associated with stroke in children, and a thorough evaluation of underlying causes is needed to determine the best treatment and prevention strategy. ⋯ Recommendations for secondary prevention are based on adult studies and the underlying pathophysiology of the stroke. Antiplatelet therapy (aspirin 1-5 mg/kg/day) is recommended in most children with a history of AIS. Although there is minimal evidence to support its use in children, anticoagulation may be indicated in AIS associated with extracranial arterial dissection, prothrombotic disorders, cardiac disease, severe intracranial stenosis, and recurrent AIS while on antiplatelet therapy.

In 2003, a multidisciplinary group of physicians formulated the first guidelines for the management of severe traumatic brain injury in infants and children. Initial treatment of these patients is focused on stabilization to prevent the occurrence of secondary insults such as hypotension and hypoxemia. However, this article focuses on the established and emerging therapies used in the intensive care unit management of intracranial hypertension--which represents the key target for contemporary therapy of this condition. ⋯ This includes first- and second-tier therapies. This article contains a brief synopsis of this critical pathway and discusses important new developments for the management of this condition. Key new developments include a better understanding of the optimal cerebral perfusion pressure target for intracranial pressure-directed therapy, with emerging evidence supporting the use of two therapeutic modalities, mild-moderate hypothermia and decompressive craniectomy.

Orf is a parapoxvirus infection of sheep and goats that causes blistering lesions on the lips, nostrils, udders or toes of affected animals. Human contact can cause transmission by direct inoculation. Human orf has typically been confined to rural settings. ⋯ The lesions resolved completely after 1 month without treatment. Although relatively rare and benign, this infection is probably under-reported and over-treated in this country. This case highlights the fact that urban physicians can expect to encounter once rare or solely rural-based infections with increasing frequency.

The treatment of childhood headaches requires a thorough investigation of the underlying etiology, including the use of standardized diagnostic criteria, and neurologic and comprehensive examinations. If secondary headaches are identified, the headaches should resolve with treatment of the underlying cause. ⋯ This includes acute therapy, preventative therapy, and biobehavioral therapy. All of these components need to be addressed in the treatment of childhood headaches, and clear goals of treatment must be discussed with the patient and parents.
