Review[Immune-mediated / inflammatory and hereditary neuropathies - overview and diagnostic algorithm].
This paper is a practical survey of immune-mediated, inflammatory and hereditary neuropathies along with recommendations for diagnostic procedures. The large group of immune-mediated, inflammatory neuropathies includes the Guillain-Barré syndrome and chronic-inflammatory demyelinating polyradiculoneuropathy and their subtypes, vasculitic, paraneoplastic and paraproteinemic neuropathies as well as neuropathies resulting from connective tissue disorders. ⋯ Research into the genetic causes has made significant progress in the last 20 years; up to now more than 80 genes mutated in hereditary neuropathies have been identified. Besides classification into axonal, demyelinating or intermediate neuropathies based on electroneurography, distinguishing between sensorimotor, pure motor and (autonomous) sensory neuropathies as well as consideration of particular clinical features and ethnic origin can be helpful in orientating molecular genetic analysis.

In order to protect non-smokers, the federal states of Germany have adopted a law that provides for extensive smoking bans. In many of these federal laws, acute psychiatric facilities are treated as an exception. Therefore, it is often up to the institutions themselves to develop and enforce regulations. The aim of this study was to evaluate the situation in acute psychiatric facilities. ⋯ Currently, the issue of smoking in psychiatric facilities does not receive enough attention. The physical and mental health of psychiatric patients would benefit from a smoke-free policy. In order to achieve this, psychiatric staff and patients need appropriate support.

Review Comparative Study[Web-based field studies on diagnostic classification and code assignment of mental disorders: comparison of ICD-11 and ICD-10].
The German Society for Psychiatry, Psychosomatics and Psychotherapy (DGPPN,) conducted a comprehensive field study (principal investigator WG) funded by the German Federal Ministry of Health in cooperation with 4 other German medical societies in the field of mental health (DGPM, DGPPR, DeGFS, DGfS) * to support WHO's development of the ICD-11 (Chapters 6 and 17). The objective of the web-based field study was to compare ICD-10 and ICD-11 (beta draft) for selected mental disorders, regarding consistency, accuracy and assessment of utility. The first study (TP1) focused on the diagnostic classification and the second (TP2) on assignment of diagnostic codes. ⋯ This may be a result of the greater complexity for coding use of the ICD-11 (e. g., due to 'post-coordination'), as well as greater familiarity with the ICD-10 system (which German clinicians currently use) and lack of practice with the new ICD-11 codes and tools. In spite of this, users assessed the ICD-11 system as more useful than the ICD-10, in part also because of ICD-11's more systematic and comprehensive coding tools. In addition, time needed for coding improved with practice, indicating need for intense education and training initiatives when ICD-11 is adopted and implemented into clinical practice.

Review[Stroke Mimics and Stroke Chameleons: Differential Diagnosis of Stroke].
The analysis of misdiagnosis of stroke has become increasingly relevant because of the time pressure in the thrombolytic treatment of ischemic strokes. Within the narrow time window of thrombolysis, a false-positive stroke diagnosis can lead to a faulty and potentially dangerous thrombolysis. The terms "Stroke Mimic" (SM = false-positive stroke diagnosis) and "Stroke Chameleon" (SC = false-negative stroke diagnosis) have been introduced for misdiagnosis in this field. ⋯ The rate of SC during the stages of treatment drops from about 50 % in the preclinical stage to about 2-5 % in stroke units. The rates of SM and SC are inversely linked: a reduction in the SM rate leads to a more critical diagnosis of stroke, thus increasing the number of underdiagnosed stroke cases as SC, and vice versa. While SM rarely lead to the legal consequences of treatment error, SC often give rise to accusations of medical errors.

Review[Hope for Huntington's disease patients: first clinical gene silencing study in progress].
Huntington's disease (HD) is an autosomal-dominant inherited neurodegenerative disorder, characterized by motor, psychiatric and cognitive symptoms for which as yet no causal treatment is available. It has a prevalence of 1 : 10 000 in Germany. Its cause is a mutation in the Huntington gene (CAG-repeat). ⋯ One way to achieve gene silencing is the use of antisense oligonucleotides (ASO) that bind to pre-mRNA. Since August 2015, a first clinical trial with ASO (study drug: IONIS-HTTRx) in early manifest HD patients is in progress (NCT02519036). Results from this study could lead to a first causal treatment option in HD.
