    Abstract: Up to 10% of patients with low back pain develop chronic low back pain. By definition, this is a pain that has persisted for longer than three months. Patients with chronic low back pain suffer from a disease, which has serious effects on the psycho-social and physiological integrity of the persons concerned. Pain syndromes of the lumbar region are among the greatest health care system problems in industrialised countries with direct and indirect annual costs of 150 to 250 billion Swiss francs. Despite intensive treatment some patients remain symptomatic. Out of it results a complaint-driven functional under-utilisation, which leads to an alleviation of the performance and increased inactivity – the beginning of a vicious circle. A multimodal treatment concept including physio- and psychotherapy, supported by a targeted medicamentous therapy, normally improves physical functions and achieves a significant discomfort reduction. If resistance to therapy persists, it is suggestive to consider precociously minimal-invasive or invasive therapeutic options.

    Abstract: Dissection of extra- and intradural arteries is a common cause of cerebral insult in younger patients ( 〈 45 years). In patients with corresponding craniocervical injury and symptoms (carotidynie, ipsilateral headache, partial Horner syndrome, cranial nerve palsy) arterial dissection is always to be considered. Essential in diagnosing arterial dissection is the verification of the intramural hematoma and morphologic changes in the vessel (stenosis, pseudoaneurysm) by means of CT/CTA (acute phase) or MRI/MRA (subacute phase). These patients need to be monitored in an intensive care unit setting. The acute therapy includes anticoagulation or inhibition of thrombocyte aggregation. We present two cases with delayed cerebral infarction due to traumatic extra- and intradural arterial dissection after a motor vehicle accident. To perform primary diagnostic quickly and adequately may avoid permanent neurological deficit in these patients.

    Abstract: Acute low back pain is a very common symptom. Up to 90% of all adults suffer at least once in their life from a low back pain episode, in the majority of cases a nonspecific lumbago. They are, with or without sciatica, usually selflimited and have no serious underlying pathology and subside in 80–90% of the concerned patients within six weeks. Beside a sufficient pain medication and physiotherapy, reassurance about the overall benign character and the favourable prognosis of the medical condition should be in the centre of the therapeutic efforts. A more thorough assessment is required for selected patients with warning signs, so called „red flags” findings, because they are associated with an increased risk of cauda equina syndrome, cancer, infection, or fracture. These patients also require a closer follow-up and, in some cases, an urgent surgical intervention. Among patients with acute nonspecific mechanical low back pain, imaging diagnostic can be delayed for at least four to six weeks, which usually allows the medical condition to improve. From a therapeutic viewpoint, there is enough evidence for the effectiveness of paracetamol, nonsteroidal anti-inflammatory drugs, skeletal muscle relaxants, heat therapy, physiotherapy, and the advice to stay „active”. A complete relief and protection represent an out-dated concept, because the deconditioning is stimulated and the return to the workplace is needlessly delayed. Spinal manipulative therapy may provide short-term benefits in certain patients. In a multimodal therapeutic concept, the patient education should focus on the natural history of an acute back pain episode, the overall good prognosis, and recommendations for an effective treatment.

    Abstract: Acute low back pain is one of the most frequent reason for an emergency or primary care physician visit. Up to 90% of all adults will experience an episode of back pain at some point during their lifetime. Although the majority of patients have uncomplicated benign presentation and 80– 90% recover within 4 to 6 weeks, there is a small subset who has an underlying potential life-threatening etiology. Among them are aortic dissection, ruptured abdominal aortic aneurysm, vertebral osteomyelitis, spinal epidural abscess and the cauda equina syndrome (CES). The latter entails a compression of the nerve roots of the cauda equina. These patients usually present posttraumatically with the clinical triad of saddle anesthesia, bowel or bladder dysfunction and muscular weakness of the lower extremeties. A delayed diagnosis can result in a significantly increased morbidity. Therefore, early diagnosis and the initiation of the appropriate therapeutic steps are essential. A thourough anamnesis and physical examination are leading to the suspected diagosis. Below, clinical presentation, diagnosis and relevant treatment of the CES are discussed.

    Abstract: The lumbar spinal stenosis (LSS) is defined as a narrowing of the spinal canal together with neuronal and vascular structures via circumjacent bone and soft tissue. In patients aged over 65 years, the LSS is among the most frequent causes of lumbago, either with or without sciatica. The prevalence will continue to augment because of the increased life expectancy. The leading symptom is neurogenic claudicatio with lumbogluteal or sciatic pain, which occurs while walking and leads to a limitation of the walking distance. Its typical constellation of symptoms including subjective leg weakness is leading to the tentative diagnosis. Nowadays, the imaging technique of choice for the diagnosis is magnetic resonance imaging. A conservative treatment is initially sufficient in most cases. The indication for surgery is given, if the pain and limitation of walking distance are not tolerable any more. Additional fusion should be taken into account, when degenerative spondylolisthesis or other pathomorphological alterations result in an instability. Conservative and surgical therapeutic goals imply pain relief, amelioration of the physical functionality, mobility and general quality of life.

    Abstract: Normal pressure hydrocephalus (NPH) is characterized by the classic triad of symptoms including gait disturbance, urinary incontinence, and dementia. Gait impairment represents the cardinal symptom. NPH is associated with a radiological verifiable ventriculomegaly in the absence of elevated cerebrospinal fluid (CSF) pressure. Because many patients do not present with classical clinical and radiological findings, its diagnosis and management represents a challenge for the general practitioner, neurologist and neurosurgeon. Various supplemental preoperative tests, including lumbar CSF tap test or CSF outflow resistance determination, can improve the accuracy of predicting a response to surgical intervention. CSF shunt results in significant symptoms in the majority of appropriately evaluated patients. The following article discusses clinical aspects, diagnosis and current therapeutic options.

    Abstract: Malignant gliomas, among others the glioblastoma multiforme, are the most frequent brain tumors. The glioblastoma itself represents the most unfavorable tumor. In Switzerland, about 450 humans contract a glioblastoma each year. The median survival time is under 12 months, thus the prognosis is dismal despite a combination of surgery, radiotherapy and chemotherapy. Surgical resection presents the major constituent in the management of patients with a glioblastoma. Postoperative radio- and chemotherapy have beneficial effects on the survival time and quality of life. Surgical removal of glioblastomas is challenging due to their infiltrative growth pattern. Therefore, the target extent of resection can only be achieved partially. For some time now, a new in Germany developed method is used in the Neurosurgical Clinic of the Cantonal Hospital in St. Gallen: The 5-ALA-guided microsurgical resection method allows a targeted and secure surgical resection of the tumor. A preoperative administered substance colors the tumor and makes it better visible for the neurosurgeon. Consequently, the healthy brain tissue can be better distinguished from the tumor. This permits not only a larger complete surgical resection of the tumor but also minimizes the resection of healthy tissue.

    Abstract: Zusammenfassung. Ziel der Arbeit war die Untersuchung der Rolle von Depression und Bewegungsangst-Kognitionen (“fear-avoidance beliefs”) für die Bereitschaft zur Aufnahme und zur Beibehaltung körperlicher Aktivität bei Patienten mit Rückenschmerz. In die Sekundäranalyse einer randomisierten, kontrollierten Interventionsstudie gingen Daten von N = 1378 Patienten mit vorwiegend akuten Rückenschmerzen ein (58 % weiblich, mittleres Alter 49 Jahre). Personen mit hoher Depressivität und gleichzeitig starken “fear-avoidance beliefs” zeigten den niedrigsten Aktivitätsumsatz zur Baseline (kcal/Woche). Bedeutsamster Prädiktor für den Aktivitätsumsatz nach sechs bzw. 12 Monaten war neben der Baseline-Aktivität eine hohe Selbstwirksamkeitserwartung zur Baseline; Rückfälle in Inaktivität wurden v.a. durch geringe Selbstwirksamkeit und geringe wahrgenommene Vorteile von Bewegung vorhergesagt. Weder Depressivität noch Bewegungsangst erwiesen sich als bedeutsame Prädiktoren für körperliche Aktivität bzw. Rückfall in Inaktivität nach sechs bzw. 12 Monaten. Vergleichsweise stabile Konstrukte wie Depressivität oder Bewegungsangst-Kognitionen sind offenbar wenig geeignet, die Bereitschaft zur Aktivität oder tatsächliche Aktivität vorherzusagen. Es wird angeregt, verstärkt die Bedeutung von kognitiven und affektiven Aspekten situativer Entscheidungsprozesse für die Ausübung körperlicher Aktivität zu thematisieren.

    Abstract: Several studies indicate that the frontal cortex is sensitive to the toxic effects of alcohol. Recent studies of our group revealed an impairment of alcohol dependent subjects in object alternation. One major problem of these studies is that they all used object alternation embedded in a spatial presentation and with two spatially arranged response buttons: a left and a right hand response key. The deficit in alternation tasks may be due to problems in processing these spatial features. We investigated 24 detoxified alcohol dependent patients, who were in a long term treatment program, and 28 control subjects matched for intelligence and age, using a new object alternation paradigm avoiding confounding of spatial effects. The results indicate that object alternation is impaired in long term alcohol dependent patients without amnesic syndrome, even when no differential spatial response is afforded. We suggest that internal control on a cognitive level, as well as on a behavioral level, may be a fundamental problem in addiction and might be related to ventromedial and orbitofrontal dysfunction.
