A language-based sum score for the course and therapeutic intervention in primary progressive aphasia.

Background: With upcoming therapeutic interventions for patients with primary progressive aphasia (PPA), instruments for the follow-up of patients are needed to describe disease progression and to evaluate potential therapeutic effects. So far, volumetric brain changes have been proposed as clinical endpoints in the literature, but cognitive scores are still lacking. This study followed disease progression predominantly in language-based performance within 1 year and defined a PPA sum score which can be used in therapeutic interventions.

A randomized controlled comparison of seclusion and mechanical restraint in inpatient settings.

Objective: No evidence is available on the relative restrictiveness of seclusion and mechanical restraint, although guidelines recommend use of the least restrictive intervention. This study compared the restrictiveness of these interventions from patients' point of view.

Methods: Data were collected from three general psychiatric admission units in South Germany.

Prediction of duration and success rate of unrelated hematopoietic stem cell donor searches based on the patient's HLA-DRB1 allele and DRB1-DQB1 haplotype frequencies.

Rapid identification of a matched unrelated donor is essential for patients in need of hematopoietic SCT. We carried out a retrospective evaluation of 549 unrelated donor searches (UDSs), which were completed in 2005 for 23 German transplant centers. On the basis of the patient's HLA-DRB1 allele and DRB1-DQB1 haplotype frequencies, UDSs were divided into four groups with different search success probability predictions.

Feasibility of randomized controlled trials on seclusion and mechanical restraint.

Background: In psychiatry seclusion and mechanical restraint are most commonly used in the management of violence and self-directed aggression. Both interventions are considered as efficacious and indispensable. Yet, these measures can have deleterious effects on patients.

Congenital dyserythropoietic anemia type I (CDA I): molecular genetics, clinical appearance, and prognosis based on long-term observation.

Congenital dyserythropoietic anemia type I (CDA I) is a rare autosomal recessive disorder with ineffective erythropoiesis and iron overloading. More than 100 cases have been described, but with the exception of a report on a large Bedouin tribe, these reports include only small numbers of cases, and no data on the lifetime evolution of the disease are available. Since 1967, we have been able to follow 21 cases from 19 families for up to 37 years.
