Modern rehabilitation is becoming more and more "social integration" instead of "going back to work". Therefore rehabilitation is also a matter in chronic disease and in old people. Parkinson patients are somewhat disabled in nearly every aspect of their life, although the extent is related to the stage of the disease. Moreover, symptoms do not respond equally to drug treatment, balance (with succeeding falls) and swallowing being special problems for anti-parkinsonian drug treatment, but also vegetative symptoms, dysarthria, motor skills etc. Apart from medication patients get relief also from adjuvant therapy like physiotherapy, occupational therapy, and speech therapy, which all can lead to improvement of quality of life. Rehabilitation needs team effort. Patient and family supporting groups (like Parkinson Disease Society and others) are an important factor for all needs of neurological rehabilitation.

The role of drug abuse as a risk factor for cerebrovascular events has been underestimated, particularly in patients with juvenile stroke. The drug most often associated with acute cerebrovascular events is cocaine. After cocaine hydrochloride abuse intracerebral hemorrhages or subarachnoid hemorrhages--predominantly caused by ruptured aneurysms or arteriovenous malformations--are by far the most frequently observed cerebrovascular complications, whereas on abuse with the alkaloidal form ("crack") intracranial hemorrhages and ischemic strokes are encountered with equal frequency. In most cases, the time interval between drug abuse and the cerebrovascular event is less than 3 hours. Several pathophysiological mechanisms are discussed as serving as triggers for the cerebrovascular event, either alone or in combination. No specific antidote to cocaine is known. Nevertheless drug screening (urine analysis) should be performed immediately to allow optimal management of patients with drug-associated acute cerebrovascular events, especially in cases with juvenile stroke.

Sixty-three headache patients (migraine: n = 28; tension-type headache: n = 35) who fulfilled the IHS criteria of 'drug abuse' were investigated by means of the Minnesota Multiphasic Personality Inventory (MMPI) and the Critical Flicker Frequency (CFF) analysis. The results were compared to those of 63 headache patients without drug abuse (matched-pair case-control study). With respect to the MMPI results, no statistically significant differences between patients with drug abuse and patients without drug abuse were found. However, patients with drug abuse showed significantly decreased CFF values compared to patients without drug abuse. This was true both for patients with migraine and for patients with tension-type headache. Thus, CFF analysis may serve as a useful method to differentiate between headache patients with drug abuse and those without drug abuse.

The various forms of treatment (drugs as well as non-drug therapy) of patients suffering from tension type headache are presented. Analgesics and non-steroidal antirheumatics are used in the management of episodic tension type headache, as well as acute exacerbation of chronic tension type headache. In view of the presumably multifactorial pathogenesis, a multidimensional therapeutic approach is required in patients with chronic tension type headache. Antidepressive drugs (thymoleptics) are usually prescribed as basic therapy. Additional implementation of non-drug therapeutic measures tailored to individual symptomatology is advisable, such as EMG biofeedback, other relaxation techniques, massage, physiotherapy and--in selected cases--psychotherapy or acupuncture.

The highly potent neurotoxins produced by Clostridium botulinum lead to botulism when ingested in appreciable amounts. However, botulinum toxin injections delivered intramuscularly in very small quantities can produce a therapeutically intended focal paresis while producing only negligible local or systemic side effects. Over the past several years, various neurological disorders, especially those involving increased muscle tone and/or abnormal movements, have been successfully treated with local botulinum A toxin injections. The success of this method has led to a general change in the management of blepharospasm, torticollis spasmodicus, hemifacial spasm, and other disorders. Treatment is usually effective for 4 to 12 weeks; if symptoms recur, the injections can be repeated over a period of several years, usually with the same success. Side effects depend on the site of the injections, and are rare at the optimal dosage and always reversible. For optimum therapeutic results, this treatment must be restricted to specialized centers.

Simulation free field hearing by head phones by means of digital filter technics was used to investigate directional hearing and audiocinetic vection in microgravity. Our data showed basic informations for the understanding of the reciprocal influence of vestibular and auditory inputs for dynamic orientation. The technical equipment of free field hearing simulation by headphones and the performed experiments are described in detail. Furthermore the new established technology is discussed in terms of the value in psychoacoustic research as well as in clinical practice.

This study presents the history and clinical findings in 80 patients suffering from tension-type headache diagnosed according to the criteria (group 2) proposed in 1988 by the Headache Classification Committee of the International Headache Society (IHS). The aim of this investigation was to evaluate the extent to which the symptomatology in our cases still corresponds with the clinical picture of tension headache described in the older literature. A positive family history of headache was obtained in 59% of the patients; mothers of headache patients were affected five times more often than fathers; a history of migraine was reported as frequently as tension-type headache in the families of the investigated patients. The first manifestation of headaches arose almost exclusively in the first four decades of life, whereby two peaks (15-20 and 35-40 years) were observed in patients with the episodic form. Headache in younger patients showed no distinct diurnal pattern; headache in older patients, however, predominantly occurred immediately after awakening from sleep or in the morning. Changes of weather and psychosocial stress were the most frequent precipitating factors; additionally, the premenstrual period, occupational stress, and sleep deprivation were precipitating factors in female patients. Bilateral pain was most often located in the occipital/nuchal, in the frontal, and the periorbital regions. Headache was usually described as pressing/tightening in quality. Difficulties in concentration and the need of rest were the most important associated symptoms. Photophobia, phonophobia and autonomic symptoms were less frequent and are probably partially drug-related and may also be due to the fact that the selected group of patients suffered from severe forms of headache. 33 of our 80 patients belonged to the subgroup "with disorders of pericranial muscles" (IHS criteria: groups 2.1.1., 2.2.1). A remarkable low percentage of patients, especially of the male sufferers, reported regular smoking and/or drinking habits. Oral contraceptives influenced neither frequency nor intensity of headache attacks. Signs of depressive disorders were present in 28% of the female patients. The differences in symptomatology of tension-type headache between patients with episodic and chronic forms, between female and male patients, and also between younger and elderly patients are documented and have to be taken into account in the diagnostik evaluation of this condition.

In this case report a 19-year-old girl suffering from hypereosinophilia with 3500 cells/mm3 and involvement of the right lung, lymph nodes, skin, serosa and heart is described. Within 10 days of admission an infiltration of the right upper lung lobe disappeared spontaneously and was diagnosed as transient eosinophilic lung infiltration according to Löffler. Both lymph node needle biopsy and several skin biopsies revealed merely general reactive changes whereas a bronchial lavage produced a significant number of eosinophilic granulocytes. Autoimmunologic or infectious-toxic disorders were ruled out as etiologic causes. Within 4 weeks after admission severe mitral and tricuspidal insufficiency as well as AV-block second grade and protodiastolic galloping rhythm developed in addition to progressing polyserositis. The echocardiographic pattern was in accordance with restrictive endocarditis. Due to the greatly reduced left ventricular ejection fraction cortisone (125 mg prednison equivalent) was tentatively administered as therapy. Within 2 weeks heart-, serosa- and lymph-node-findings became normal as well as the eosinophilic count, the scaling skin rash being only partly improved. After 10 months of continuous cortisone therapy (10 mg prednison equivalent) the patient was without evidence of disease. However in conclusion, it may be said that such pattern of findings suggests a hypereosinophilic syndrome with Löffler endocarditis with an unknown future course of disease although generally survival prognosis may not be too high.
