Pancuronium(bromide) is used because of its relaxing effect on striated muscles and usually requires artificial respiration. A 52-year-old woman suffered from long-standing "generalized dystonia", which had become resistant to conventional therapy. Therefore, an anesthetist established a permanent medication scheme with pancuronium using a PCA pump. This pump had been controlled by the patient herself ensuring an acceptable quality of life with broad personal autonomy. Finally, the woman was found dead in her flat by a member of a home nursing service. The infusion hose showed a fixed knot and further blocking by a clamp. The autopsy findings were non-specific, except for the presence of opioid tablets in the colon. Toxicological analyses showed 72ng/ml pancuronium and 21 ng/ml oxycodone (therapeutic) in the femoral venous blood. The range of published pancuronium levels varies from approx. 80 to 2,000 ng/ml. Thus it had to be assumed that the pancuronium level was too low (72 ng/ml) so that symptoms of dystonia recurred. Based on extensive literature research, the described case can be qualified as unique. The therapy concept had been innovative, sufficient and effective for more than 10 years. It allowed the patient to enjoy a maximum of autonomy. Ultimately, death was due to the blocked pancuronium infusion. The relatively low pancuronium level had provoked the dystonia to return with generalized spasms also involving the respiratory muscles resulting in respiratory arrest. During the police investigations, two previous suicide attempts came to light.

The purpose of this study was to assess whether alexithymia is a risk factor for autonomic dysregulation in cervical dystonia (spasmodic torticollis, ST). Alexithymia was assessed by an authorized German version of the TAS-20. In a first step, we recruited 10 ST-patients with high alexithymia scores (> 62; M = 69.2, SD = 3.0) and compared them with 10 ST-patients with low alexithymia scores (< 35; M = 28.7, SD = 4.3) on physiological and subjective responses to a cognitive and an emotional laboratory stressor. High-alexithymic ST-patients generally showed increased levels of autonomic arousal (higher SCL, more NS.SCF and lower T; 0.016 /= 57 vs. low

Dystonia is a rare neurological complication after peripheral trauma. Incidence and pathophysiology of post-traumatic dystonia are not known. Predisposing factors are sympathetic reflex dystrophia, pre-existing movement disorders or a family history of movement disorders. The main diagnostic goal is to exclude other causes of secondary dystonia. Objective criteria for posttraumatic dystonia are not established, and therefore differentiation from psychogenic dystonia frequently remains difficult. Careful psychiatric examination is obligatory. Clinical criteria are consistency of the symptoms over time and the presence of symptoms compatible with organic dystonia. Polygraphic EMG examinations provide objective correlates of the movement disorder, but exact EMG criteria for the diagnosis of dystonia have yet to be established.

We report on a case of a female who had developed a fixed flexion contracture of the 4th and 5th fingers of the right hand which was painless and at-rest right in the beginning at the age of 19. By means of neurographical examinations a hereditary neuropathy with liability to pressure palsies was established in her and her mother, which had clinically manifested with symptoms of the ulnar nerve at the affected hand. The dystonic symptoms did not show any progression within ten years follow-up. A remarkable feature of the course was the twice repeated occurrence of short, sudden and complete remissions immediately following invasive diagnostic procedures. The thorough discussion of differential diagnostic aspects and the analysis of the familiar situation and psychodynamics of the patient resulted in the diagnosis of a psychogenic hand dystonia.

Dystonic movements and other dyskinesias often cause diagnostic difficulties due to their complex symptomatology. Namely focal dystonias are frequently misdiagnosed as conversion reactions. Idiopathic dystonias are generally considered a nonstructural (neurobiochemical) disorder of the basal ganglia. Many case reports, however, have dealt with patients presenting with "atypical" dystonia whose symptoms were relieved by psychotherapy or hypnosis. We present the histories of two young women exhibiting focal dystonia emerging for the first time under circumstances of profound emotional trouble. We discuss the general difficulties in the diagnosis of dystonic movement disorders and review the criteria for the diagnosis of "psychogenic dystonia". The basal ganglia integrate limbic, proprioceptive and sensorimotor inputs to create emotionally and functionally appropriate voluntary movements. Therefore, the traditional dichotomy "psychogenic-somatogenic" appears to be inappropriate when applied to extrapyramidal movement disorders. In a psychosomatic understanding, the assumption of a psychogenic "trigger" for a somatic movement disorder does not mean a contradiction.

30 patients with writer's cramp were examined by a neurologist and a psychiatrist. The syndrome was frequently associated with a postural tremor. We found no evidence for a peripheral causation. Electromyographical recordings showed co-contractions of agonists and antagonists as well as individual patterns of increased muscle activity during writing. CT and MRI scans were normal in most patients. The psychiatric examination revealed a history of situational stress at the onset of the disease and also some abnormalities in the biography and personality traits. Since the latter findings were not consistently present we have no evidence that the disease is a neurotic manifestation. We consider it likely that secondary psychoreactive processes may have some significance in the individual patient.
