Abstract
A new S2k AWMF guideline for the treatment of idiopathic facial palsy has been published. An accurate differential diagnosis is indispensable as 25-40% of all facial palsy cases are of non-idiopathic origin. It is explicitly recommended to treat patients with idiopathic facial palsy with steroids. Steroids favour a complete recovery, decrease the risk of synkinesis, autonomic sequelae and contractures. Adjuvant antiviral therapy cannot be recommended. On current data there is not sufficient evidence that the combination of steroids with antiviral drugs has a benefit for the patients. Even when not supported by randomized trials, adjuvant symptomatic therapy to protect the cornea and to avoid complications is recommended. There is no scientific evidence that physical therapy has any benefit but it should be taken into account because of psychological reasons. A benefit of acupuncture has not been proven. If eye closure remains incomplete as result of defective healing, one therapeutic option is lid loading of the upper eye lid. Moreover, in case of severe persistent palsy, several well-established microsurgical nerve and muscle plasty procedures are available.

Abstract
To present two patients with Miller Fisher syndrome (MFS) recurrence after 35 and 44 years and review of the literature on recurring MFS. All identified cases with recurrent MFS were evaluated. Age, gender, clinical features of first and recurrent MFS, course of disease, laboratory findings, therapy and outcome were transformed into tables. Twenty-eight patients (16 men, 12 women; mean age at the first episode 34 years (range 13-57 years); mean age at the latest episode 47 years (range 21-66 years) with a total of 70 MFS episodes were identified. Twenty-one patients had a single recurrence, five patients had two recurrences, one patient had four recurrences and one patient had seven recurrences. The mean interval between attacks was 9.45 years (3 months to 44 years). In 76% of the initial episodes and in 81% of the recurrent episodes, an infectious disease preceded MFS. Additional facial and bulbar symptoms and autonomic disturbances were frequent findings. Cerebrospinal fluid (CSF) and electrodiagnostic findings were unspecific. If tested, autoantibodies against GQ1b had been positive in all episodes. In about half of the patients, immunotherapy was applied. The outcome was favourable in most patients. Recurrence of MFS is a rare quite uniform condition with a mostly favourable prognosis.

Abstract
OBJECTIVE The aim of the study was to assess the occurrence and the frequency of chemosensory dysfunction in patients with polyneuropathy (PNP). METHODS We performed a prospective observational study. Olfactory function was assessed using the standardized 'Sniffin' Sticks' test to measure odor threshold for phenyl ethyl alcohol, odor discrimination, and odor identification. Gustatory function was assessed using the standardized 'taste strips' test. In addition, we assessed etiology, neurophysiology, and severity of the PNP, and the patients' comorbidities and medication. RESULTS A total of 53 consecutive patients were enrolled (15 women, 38 men; mean age 61 years); 27 of them (51%) exhibited olfactory dysfunction and 23 of them (43%) gustatory dysfunction. Patients with diabetic PNP had significantly lower taste scores than patients with inflammatory, genetic, or idiopathic PNP. In addition, odor identification was negatively correlated with PNP severity. CONCLUSION The applied bedside tests are useful to detect chemosensory dysfunction in patients with PNP. Chemosensory dysfunction is quite frequent in these patients.

Abstract
OBJECTIVES In a pilot study we found a correlation of the clinical outcome with adhesion molecule (AM) concentrations in ventricular cerebrospinal fluid (CSF) but not in serum in patients with intracerebral haemorrhage. We now determined the time course of AM concentration in CSF and serum after basal ganglia haemorrhage (BGH) in order to further uncover pathogenetic mechanisms. MATERIALS AND METHODS We included 11 patients with acute BGH and ventricular tamponade in which an extraventricular drainage had been applied to treat ventricular ballonade. Paired CSF and serum samples were obtained within 8 h after onset of BGH, as well as on the consecutive days 2, 4, 6, and 8, respectively. The concentrations of soluble ICAM-1 (sICAM-1) and VCAM-1 (sVCAM-1) in CSF and serum were measured by enzyme-linked immunosorbent assay. Moreover, we determined blood volume and perifocal oedema by a semi-automated planimetry technique from initial cranial computed tomography scans. RESULTS sICAM-1 and sVCAM-1 levels in CSF were highest within the first hours after onset of BGH, then decreased significantly (P < 0.005 and <0.05, respectively) on day 2 and slightly increased thereafter. Furthermore, BGH volume was significantly correlated with the concentrations of sICAM-1 (r = 0.63, P < 0.05) and sVCAM-1 (r = 0.66, P < 0.05) in ventricular CSF but not in serum. CONCLUSIONS Our results might indicate that the local inflammatory reaction is pronounced early after onset of BGH and appears to be restricted to the central nervous system. Moreover, AM concentrations measured early after BGH onset correlated stronger with radiological and clinical data than follow-up measurements.

Abstract
Like with many sensory abilities a reduction of taste and smell occurs during aging. Since there are hints to an additional reduction in dementing diseases, we assessed 52 patients, 26 women and 26 men, who were presented to a memory clinic, using the Sniffin' Sticks, Whole Mouth and Taste Strip Tests. While smoking, alcohol consumption, intake of drugs and sex exerted only minor impact, age and the severity of cognitive impairment were of major importance. There was a moderate but significant correlation between the severity of dementia, taste and smell, even if the age effect was partialled out. Notably, patients with Parkinson syndrome showed worse taste and smell abilities than those without. Here the differences were indeed marked enough to play a possible role in making the diagnosis. This exploratory study confirms a mild reduction of gustatory function in dementing diseases over and beyond that of normal aging which--in addition to a reduction of smell--seems to be especially marked in Parkinson syndromes.

Abstract
In caring for patients with taste disorders, the clinical assessment should include complete examination of the cranial nerves and, in particular, gustatory testing. Neurophysiological methods such as blink reflex and masseter reflex allow the testing of trigeminofacial and trigeminotrigeminal pathways. Modern imaging methods (MRI and computed tomography) enable the delineation of the neuroanatomical structures which are involved in taste and their relation to the bony skull base. From a neurological point of view, gustatory disorders can result from damage at any location of the neural gustatory pathway from the taste buds via the peripheral (facial, glossopharyngeal and vagal nerve) and central nervous system (brainstem, thalamus) to its representation within the cerebral cortex. Etiopathogenetically, a large number of causes has to be considered, e.g. drugs and physical agents, cerebrovascular disorders including dissection of the carotid artery and pontine/thalamic lesions, space-occupying processes - in particular tumors compressing the cerebellopontine angle and the jugular foramen of the skull base - head trauma and skull base fractures, isolated cranial mononeuropathy (e.g. Bell's palsy) or polyneuropathy, epilepsy, dementia, multiple sclerosis and major depression. In addition to this, aging can also lead to diminished taste perception. Due to the broad differential diagnostic considerations, it is essential to look for additional, even mild, neurological signs and symptoms. Treatment must relate to the underlying cause. Zinc may be tried in idiopathic dysgeusia.

Abstract
Neck pain is frequent and can be a symptom of numerous differential diagnoses with quite different diagnostic and therapeutic consequences. A 37-year-old woman reported acute neck pain aggravated by movements of the cervical spine and head and by swallowing. Clinical examination showed pronounced neck stiffness. T2-weighted MRI demonstrated high-intensity edema and effusion localized prevertebrally in the area of the superior part of the longus colli muscle. Computed tomography of this region demonstrated prevertebral calcification leading to the diagnosis of retropharyngeal tendinitis. Nonsteroidal antiphlogistic drugs led to rapid improvement of clinical signs and symptoms. Retropharyngeal tendinitis should be considered in patients with acute neck pain.

Abstract
OBJECTIVE To investigate the frequency of acute stroke in patients with a recent travel history and to analyse risk factors, stroke patterns and presence of a patent foramen ovale (PFO) in this patient group. DESIGN One-year prospective observational study. SETTING Single-centre study. METHODS Enrolling all patients presenting with a first cerebral ischaemia and complementing the usual history with a standardised travel history. RESULTS Of 338 patients with acute stroke, 42 had a positive travel history (PTH) (12.4%). Patients with a PTH were significantly younger (56.6 (SD 13) years) than patients (66.9 (13.2) years, p = 0.0001) with a negative travel history (NTH). Frequency of PFO in the PTH group (13; 44.8%) was significantly higher than in the NTH group (7; 10.8%) (p = 0.0001), even after patients were dichotomised into two age groups (younger and older than median of all PATIENTS 31% v 6.1%, p = 0.007 and 13.8% v 4.6%, p = 0.022, respectively). PTH patients had fewer stroke risk factors (2.2 (1.4) v 3.3 (1.6), p = 0.0001) and a different risk profile with a lower frequency of diabetes (11.9% v 31.4%, p = 0.009), hypertension (52.4% v 78.7%, p = 0.0001), atrial fibrillation (7.1% v 22%, p = 0.025) and others (16.7% v 38.9%, p = 0.005). In contrast, PTH patients had significantly more cardioembolic (35.7% v 19.3%, p = 0.023) and cryptogenic strokes (50% v 19.9%, p = 0.0001) and more often ischaemia in the territory of the posterior cerebral artery (29.6% v 6.3%, p = 0.0001). CONCLUSIONS The finding that more PTH patients had a PFO and a cardioembolic stroke pattern but that fewer had other typical stroke risk factors led to the hypothesis that PFO is a risk factor for economy class stroke syndrome.

Abstract
OBJECTIVES A review is given on various methods, preconditions and pitfalls of apnea testing for the diagnosis of brain death. MATERIALS AND METHODS An extensive medical data base search was implemented by information gathered from books and our own experience with more than 2000 apnea tests. RESULTS While testing for apnea (AT) is considered indispensable worldwide, recommendations and handling differ. Rather than relying on elapsed time, a specific target value for the partial arterial pressure of carbon dioxide (PaCO2) should be aimed at being the maximum physiological stimulus for respiration. Methodological points are elaborated upon in detail for apneic oxygenation and hypoventilation. CONCLUSION AT is an indispensable element of diagnosing brain death. Although with proper handling and adequate precautions AT is safe, it should be performed as a last resort. An international agreement on target values for the PaCO2 is desirable.

Abstract
Modern stroke care requires urgent initiation of treatment. Thus, rapid recognition of cerebrovascular incidents by medical laypersons is mandatory. Accordingly, public knowledge of stroke warning signs and adequate action is very important. Little is known about the level of knowledge among the general public and use and effect of various sources of information. In first aid training programs conducted by the St. John Ambulance in Bavaria, participants were questioned if and from what source they already got information about stroke. Additionally they were asked to list stroke warning signs and to describe what a stroke is. Altogether 532 subjects filled out the questionnaire; 419 stated that they already had heard something about stroke (53.7% male, mean age 29.4 years). Sources of information were: personal experience with affected patients (30.1%), TV/radio (22.1%), newspaper (18.4%) and relatives/friends (17.2%). Subjects with prior information listed significantly more warning signs/symptoms compared with those without previous information (1.76 vs. 0.63; p<0.01). Participants using the source "TV/radio" named fewer warning signs than those using the sources "newspaper" or "affected patients" (p<0.01). Prior information was effective in enhancing knowledge about stroke. However, we found significant differences related to the source of information. Since experiences gathered from personal contact with affected patients were stated most frequently, leading to better knowledge than information gained from mass media, subsequently acute care and rehabilitation would be a good opportunity for providing information about stroke to proxies and visitors of the patients.

Abstract
In the treatment of dysgeusia, the use of zinc has been frequently tried, with equivocal results. The aim of the present randomized clinical trial, which involved a sufficiently large sample, was therefore to determine the efficacy of zinc treatment. Fifty patients with idiopathic dysgeusia were carefully selected. Zinc gluconate (140 mg/day; n=26) or placebo (lactose; n=24) was randomly assigned to the patients. The patients on zinc improved in terms of gustatory function (p <0.001) and rated the dysgeusia as being less severe (p <0.05). Similarly, signs of depression in the zinc group were less severe (Beck Depression Inventory, p <0.05; mood scale, p <0.05). With the exception of the salivary calcium level, which was higher in the zinc patients (p <0.05), no other significant group differences were found. In conclusion, zinc appears to improve general gustatory function and, consequently, general mood scores in dysgeusia patients.

Abstract
The authors investigated 17 patients with idiopathic intracranial hypertension (IIH), correlating laser scanning tomography of the optic nerve with CSF opening pressure. The decrease in papilla volume and papilla height showed a linear correlation with the opening pressure of the CSF (r = 0.59, p < 0.001; r = 0.63, p < 0.001). If the CSF opening pressure is higher than 20 cm water, an increase of 5 cm water CSF pressure corresponds to a papilla volume increase of 0.95 mm3 as well as a papilla height increase of 0.34 mm.

Abstract
Computed tomography (CT) is the standard method of brain imaging in acute stroke. To an experienced examiner, nonenhanced CT will exclude hemorrhage and may indicate early ischemic signs. Reliable description of an ischemic area and the underlying vascular disease is not possible in the acute phase but is possible, particularly within the first hours, when therapeutic decisions on matters such as systemic thrombolysis are to be made. For such rapid decision-making, imaging must provide more information. Novel, contrast-enhanced CT techniques can provide this information. Perfusion CT (CTP) can show brain perfusion, allowing one to distinguish between reversible and irreversible damage in an ischemic area. Also, CT angiography (CTA) can detect occlusion or stenosis in the relevant vasculature. Using a modern, multislice CT scanner, it is now possible to combine these modalities of imaging. In a fast protocol for emergency evaluation, all three methods can be performed and evaluated to provide the crucial information within 15 min. In the first 102 patients examined within 6 h of symptom onset using this protocol, multimodal CT contributed substantially to therapeutic decisions, even though there are some limitations in these methods.

Abstract
BACKGROUND AND OBJECTIVE Stroke care in Germany has substantially improved during the last decade. One column of modern stroke care is the institution of stroke unit which allows rapid diagnosis and treatment. The aspect of admission of nonstroke patients to a stroke unit is poorly evaluated. The aim of this study is to evaluate the number of patients who are admitted to a national stroke unit but do not suffer from stroke. Furthermore, we related the proportion of nonstroke referrals to the different referral modes. PATIENT AND METHODS Observational study recording all suspected stroke referrals with regard to final diagnosis and type of referral during a 12-month period (1.8.2002-31.7.2003). RESULTS 462 patients were admitted by 4 routes: 74 by paramedics or by self-presentation, 138 by emergency physicians, 144 by primary care doctors, and 106 were transferred from other hospitals. 88 patients (19 %) finally revealed no acute stroke. The most common nonstroke diagnoses were seizure (20 %), dissociative disorders (14 %), cranial nerve disorders (11 %), hypoglycaemia (8 %) and transient global amnesia (7 %). There was no significant difference among the proportion of nonstroke patients referred by ambulance paramedics and self-presentation (15 %), emergency physicians (21 %), primary care doctors (15 %) and interhospital transfer (24 %) [p = 0.222, X (2)-test according to Pearson]. CONCLUSION Due to the fact that a number of clinical neurological conditions mimic acute stroke, misdiagnosis of stroke is common. We advocate that all stroke patients are seen early in the course of the disease by a neurologist. An alternative could be that in stroke units of internal medicine hospitals patients are seen by a consulting neurologist. Alternatively, telemedicine might be used and the neurologist on duty of a neurological stroke unit could be consulted.

Abstract
HISTORY AND CLINICAL FINDINGS A 61-year-old man was admitted to hospital because of right-sided hypaesthesia. Additionally he reported a brief speech disturbance some weeks before. Neurological examination indicated right-sided sensomotoric hemiparesis and left-sided upper quadrant anopia. 6 years ago recurrent transient ischaemic attacks (TIA) was diagnosed caused by paradoxical embolism through a persistent foramen ovale (PFO). The PFO was closed with a 45 mm Sideris button occluder device. After this, he reported no symptoms of cerebral ischaemia and he did not take any antiplatelet therapy. INVESTIGATIONS Transesophageal echocardiography (TEE) showed a left atrial thrombus attached to the occluder. Cerebral computed tomography revealed infarction in regions supplied by the right posterior cerebral artery and left media cerebral artery. As additional risk factor for thrombosis a heterozygous factor V Leiden mutation was diagnosed. DIAGNOSIS Multiple cerebral infarctions caused by a thrombus attached to an occluder system 6 years after interventional closure of persistent foramen ovale in a patient with heterozygous factor V Leiden mutation. TREATMENT AND COURSE The patient was anticoagulated (phenprocoumon) and the thrombus gradually dissolved. CONCLUSION A thrombosis on a Sideris occluder device may cause cerebral infarctions even years after transcatheter closure of a PFO.

Abstract
A 76-year old woman was admitted because of severe gait ataxia and dysarthric speech that had worsened over the last 24 h. The patient was initially suspected of having repeated transitory ischemic attacks (TIAs) as her daughter reported a similar episode that had happened 3 weeks prior to admission. The onset of spontaneous twisting, choreoathetotic movements of both hands and arms and worsening of symptoms one hour after admission together with a history of lithium therapy lead to the correct diagnosis and appropriate treatment.

Abstract
We report a 57-year-old woman with neuroborreliosis presenting with headache, shoulder muscle pain and double vision. MRI demonstrated enhancement of the right third and sixth cranial nerves. A 3D MP-RAGE sequence was used to perform multiplanar reformations to show this more graphically. The patient was free of symptoms 1 month after completion of therapy, when thickening and contrast enhancement of the nerves were less pronounced.

Abstract
After 1 week of flu-like illness, a 64-year-old man developed rapidly progressive mononeuritis multiplex involving the right arm and both legs. Serologic studies identified Coxiella burnetii as the cause of the febrile disease (Q fever). Fourteen days doxycycline treatment (200 mg daily) induced rapid and complete recovery. After 6 months, flu-like symptoms, weakness and hypalgesia of the right leg reappeared. Antibody titers again identified Q fever. Doxycycline was re-established and induced prompt recovery. Q fever has been associated with various neurologic complications such as meningoencephalitis, cerebellitis, optic neuritis or polyneuroradiculitis. This is the first report on Q fever related mononeuritis multiplex. Prolonged antibiotic treatment may be required to prevent relapsing infection from the resistant bacterium.

Abstract
To assess further the psychometric features of neuropsychological deficit screening (NDS), three groups of patients (41 demented, 23 not demented but cognitively impaired, and 50 controls) were examined and the results compared with two older tests, the Mattis dementia rating scale (MDRS) and the mini mental status test (MMST). As a result, the discriminating ability of NDS (modified for this study) was comparable to both other tests without surpassing them in either demented or cognitively impaired groups. An abbreviated version allowed for an improvement in economy without sacrificing discriminating properties. The advantage of NDS thus lies in the diversity of functions assessed, while its screening power is comparable to the two other tests used for comparison.

Abstract
Intra-arterial (i.a.) and transcutaneous (t.c.) blood gas monitoring were compared with in vitro blood gas analysis (abg) during apnoea testing for the determination of brain death in a prospective observational study. All three methods were used simultaneously in 19 patients in whom brain death was suspected. Brain death was confirmed in each case adhering to the recommendations of the Scientific Advisory Board of the German Federal Chamber of Physicians which demand a PCO2 of at least 60 mmHg. In vitro parameters ranged from 23.2 to 80.4 mmHg (PCO2), 52.7 to 509.9 mmHg (PO2), and 7.072 to 7.591 (pH). The intra-individual correlations between both monitoring methods (rPCO2=0.958, rPO2=0.859) and between each of them and abg (r>0.960) were high. Absolute deviations from abg for the corrected as well as uncorrected measurements were similar for both methods, except with regard to group bias where an advantage for the i.a. values emerged. Since many of the i.a. measurements failed and the disposable i.a. probes cost much more than the t.c. electrodes, the i.a. technique at present holds no advantage over t.c. measurements in testing for apnoea in suspected brain death except where simultaneous monitoring of pH and temperature are desired.

Abstract
A 37 year old man presented with a 15 year history of ulcerative colitis. On examination he had weakness of the right arm, slurred speech and progressive confusion, followed by a rapid deterioration of consciousness and motor functions resulting in coma, tetraparesis and bilateral Babinski responses. Magnetic resonance imaging of the brain and spinal cord revealed multiple hyper- and hypointense white matter lesions. Clinical symptoms, history and neuroradiological findings led to the diagnosis of an ulcerative colitis-associated CNS disorder. An autoimmune vasculitic process may have played an important pathophysiological role, considering the vasculitic changes observed by skin biopsy as well as the rapid clinical improvement following immunosuppressive therapy with corticosteroids and azathioprine. During a follow up period of more than one year we observed continuous and complete recovery of neurologic symptoms.

Abstract
Patients with left stroke (n = 17), right stroke (n = 16), and dementia (n = 17) and healthy controls (n = 15) were asked to recognize familiar handwriting among 10 handwritten texts. All healthy controls and 96% of the left-brain-damaged patients were able to recognize the familiar handwriting, but only 44% of the right-brain-damaged and 41% of the dementia patients (none if Mini-Mental Status Test score was <18, n = 5) were able to do so. The authors conclude that the recognition of handwriting is a special skill that is independent of other verbal and lexical tasks.

Abstract
Strokes have been known since ancient times. Today, stroke is the second most frequent cause of death and the most frequent cause of invalidity. In about 80% of cases, stroke is caused by cerebral ischemia and in about 20% by intracerebral hemorrhage, subarachnoidal hemorrhage, venous thrombosis and other cerebrovascular diseases. The brain is one of the most richly perfused tissues and depends fundamentally on the supply of oxygen and glucose. In order to assure adequate cerebral blood flow, the brain is capable of autoregulation through the interaction of diverse autoregulatory mechanisms (myogenic, neurogenic and metabolic factors, blood viscosity, renin-angiotensin-system and endothelium). Reduction of cerebral blood flow below the threshold of about 25 ml/100 g x min leads to an impairment of the functional metabolism and later to impairment of the structural metabolism. Pathophysiologically, a large number of isolated pathobiochemical processes (loss of energy, lactate acidosis, excitating amino acid release, ion balance disorders, calcium overload, free radical release, etc.) start to interfere with each other. Delayed edema and inflammation lead to secondary brain damage. Apoptosis is probably induced by ischemia and can cause secondary deterioration. The basic principles in the treatment of ischemia are firstly the rapid restoration of cerebral blood flow (lysis, carotid endarterectomy) and secondly--following infarction--a limitation of brain damage (preservation of ischemic but not necrotic brain tissue, prevention of secondary complications). Stroke treatment requires profound diagnostic and therapeutic expertise and interdisciplinary cooperation of neuroradiologists, neurosurgeons, vascular surgeons and cardiologists. Stroke can best be managed in special "stroke units", which have now been established in nearly all parts of Germany. Beside acute management of stroke and neurological rehabilitative treatment, emphasis has to be laid on primary (public information, education, treatment of risk factors) and secondary prophylaxis (treatment with antiaggregants, anticoagulants, a. o.).
