Abstract
Andermann syndrome is a rare autosomal recessive disorder characterized by agenesis of the corpus callosum (ACC), progressive motor-sensory neuropathy, mental retardation and facial features. We report on two siblings with the clinical picture of a demyelinating hereditary motor and sensory neuropathy (HMSN), where only the presence of ACC in the younger brother pointed to the diagnosis of Andermann syndrome. Mutation analysis of the KCC3 (SLC12A6) gene showed a compound heterozygous mutation; a maternal missense mutation c.1616G>A (p.G539D) and a paternal splice mutation c.1118+1G>A in both siblings. We hypothesize that mutations of the KCC3 gene may result in non-syndromic childhood onset HMSN.

Abstract
BACKGROUND Ketamine is a non-competitive antagonist at N-methyl-D-aspartate (NMDA) receptors and reduces neuronal injury after cerebral ischemia by blocking the excitotoxic effects of glutamate. However, cerebral regeneration by means of endogenous neurogenesis may be impaired with blockade of NMDA receptors. The effects of S(+) ketamine on post-ischemic neurogenesis are unknown and investigated in this study. METHODS Thirty-two male Sprague-Dawley rats were randomly assigned to the following treatment groups with intravenous S(+) ketamine anesthesia: S(+) ketamine 0.75 mg/kg/min with or without cerebral ischemia and S(+) ketamine 1.0 mg/kg/min with or without cerebral ischemia. Eight non-anesthetized, non-ischemic animals were investigated as naïve controls. Forebrain ischemia was induced by bilateral common carotid artery occlusion in combination with hemorrhagic hypotension. 5-bromo-2-deoxyuridine (BrdU) was injected intraperitoneally for seven consecutive post-operative days. BrdU-positive neurons in the dentate gyrus and histopathological damage of the hippocampus were analyzed after 28 days. RESULTS The number of new neurons was not affected by S(+) ketamine in the absence of cerebral ischemia. The ischemia-induced increase in neurogenesis was reduced by high-dose S(+) ketamine. Cell death of ischemic animals did not vary between low- and high-dose S(+) ketamine. CONCLUSION While low concentrations of S(+) ketamine allow an ischemia-induced increase in the number of new neurons, high S(+) ketamine concentrations block the post-ischemic increase in newly generated neurons. This effect is irrespective of the extent of other histopathological damage and in line with studies showing that NMDA receptor antagonists like MK-801 inhibit neurogenesis after cerebral ischemia.

Abstract
Impulse oscillometry (IOS) is a computer-supported method for the measurement of complex mechanical airway characteristics. The aim of this study was to evaluate the applicability of IOS in the diagnosis of obstructive airway diseases in comparison to the standard methods of spirometry, pneumotachymetry, and bodyplethysmography. 244 patients (age 61.5 +/- 13.6 years; 61 % men) with bronchial asthma (n = 65) and chronic obstructive pulmonary disease (COPD) (n = 179) were retrospectively analysed. By means of body plethysmography (Srtot < 120%pred) an obstruction was diagnosed in 94%, by pneumotachymetry (FEV1 < 80%pred) in 78 %, and by IOS depending on the parameter chosen in 87-94% of patients. Mild and medium obstructions could be identified by means of all IOS parameters except for R20: severe obstructions, however, were better detected by means of the frequency-dependent resistance FDR and reactance at 5 Hz, X5. The parameters R5, X5, and Zrs, however, showed a tendency to underestimate the degree of obstruction. Bronchial obstruction can reliably be diagnosed by IOS when, in cases of severe obstruction, more complex parameters like FDR and X5 are included. The parameters of the standard methods (body plethysmography and pneumotachymetry) show relatively low correlations due to the different measurement methods not only in comparison to IOS but also to one another. In summary, IOS is a convenient method for patients with a low dependency on cooperation for the evaluation of obstructive airway diseases complementary to the established standard methods and, in addition, is useful as a sensitive screening tool for the early detection of bronchial obstruction.

Abstract
BACKGROUND In vivo animal experiments have shown that the cytoskeleton plays a crucial role in case of structural changes after an induced retinal detachment. This study attempts to clarify whether a retinal organ culture could serve as an in vitro model for retinal detachment and thus represent an alternative to animal experiments. The main focus of this publication lies on the early cytoskeletal changes after retinal detachment. MATERIALS AND METHODS Porcine retinas were mounted on special carriers, cultured for one or two weeks and examined by standard immunohistological (vimentin, GFAP, alpha-tubulin), as well as electron microscopical procedures. RESULTS The cytoskeletal changes revealed similar spatio-temporal pattern compared with in vivo induced retinal detachments. In addition, it was shown that microtubules might play a crucial role in the early phase of gliosis, i. e., prior to a subretinal invasion by Müller cell extensions. CONCLUSIONS The presented organ culture model will be used to unravel the largely unknown initial reactions of retinal gliosis, focusing on subcellular changes localised at the outer limiting membrane. The intracellular transport system of microtubules might play a key role in these processes.

Abstract
Diseases of the lung are one of the main causes of morbidity and mortality in the elderly. The risk of respiratory infections is increased due to structural changes, malnutrition, co-morbidity, and a variety of other factors. Bacterial and viral pathogens cause acute bronchitis and exacerbations of chronic bronchitis (AECB). Community acquired pneumonias (CAP) show a different spectrum of pathogens and clinical course in comparison to nosocomial pneumonias (hospital acquired pneumonia, HAP). Institutionalised patients are at risk of a health care associated pneumonia (HCAP), with often a different spectrum of pathogens in comparison to CAP and HAP. Elderly patients with cerebrovascular disease and impairment of swallowing or cough reflexes often suffer from aspiration pneumonias. The mortality is highest in the elderly, comorbid, and immunocompromised patient with nosocomial pneumonia. Important preventive measures include influenza and pneumococcal vaccination, avoidance of immobility, oral hygiene, and sufficient nutrition.

Abstract
Cervical cancer is often the most common cancer among women in developing countries, yet current screening efforts have not been effective in reducing incidence and mortality rates in these settings. In an effort to increase knowledge about screening participation in low-resource settings, this study sought to identify key factors affecting women's participation in a cervical screening program in north central Peru. We studied women who were exposed to various health promotion educational activities and compared a total of 156 women who sought screening between July 2001 and October 2003 with 155 women who did not. Results from logistic regression identified four significant predictors of screening: higher relative wealth, knowing other screened women, seeking care from a health facility when sick and satisfaction with services at the health facility. When we restricted our analysis to women who had experienced screening in the past, two additional predictors emerged: having a husband who was supportive of screening participation and attending an awareness-raising session. These results have important programmatic value for tailoring outreach efforts for women and indicate that different strategies may be required to best reach women who have never been screened.

Abstract
Bipolar disorders are being diagnosed with increasing frequency in children and adolescents, resulting in a need for nurses in a wide variety of settings to be aware of symptom presentation and treatment options. Symptoms can be conceptualized in a developmental context based on the Diagnostic and Statistical Manual (DSM-IV TR) criteria. Symptoms of mania can be distinguished from other disorders, including Attention Deficit Hyperactivity Disorder, even when these disorders co-occur. Treatment options can include single or combination psychopharmacologic therapy, using a variety of mood stabilizers, atypical antipsychotic agents and subsequent treatment of residual ADHD symptoms. Additionally, therapeutic interventions for the child and family are important. While additional research is needed, appropriate treatment of pediatric bipolar disorders can lead to significant improvements in functioning and development.

Abstract
BACKGROUND Lissencephaly is a neuronal migration disorder leading to absent or reduced gyration and a broadened but poorly organized cortex. The most common form of lissencephaly is isolated, referred as classic or type 1 lissencephaly. Type 1 lissencephaly is mostly associated with a heterozygous deletion of the entire LIS1 gene, whereas intragenic heterozygous LIS1 mutations or hemizygous DCX mutations in males are less common. METHODS Eighteen unrelated patients with type 1 lissencephaly were clinically and genetically assessed. In addition, patients with subcortical band heterotopia (n = 1) or lissencephaly with cerebellar hypoplasia (n = 2) were included. RESULTS Fourteen new and seven previously described LIS1 mutations were identified. We observed nine truncating mutations (nonsense, n = 2; frameshift, n = 7), six splice site mutations, five missense mutations, and one in-frame deletion. Somatic mosaicism was assumed in three patients with partial subcortical band heterotopia in the occipital-parietal lobes or mild pachygyria. We report three mutations in exon 11, including a frameshift which extends the LIS1 protein, leading to type 1 lissencephaly and illustrating the functional importance of the WD domains at the C terminus. Furthermore, we present two patients with novel LIS1 mutations in exon 10 associated with lissencephaly with cerebellar hypoplasia type a. CONCLUSION In contrast to previous reports, our data suggest that neither type nor position of intragenic mutations in the LIS1 gene allows an unambiguous prediction of the phenotypic severity. Furthermore, patients presenting with mild cerebral malformations such as subcortical band heterotopia or cerebellar hypoplasia should be considered for genetic analysis of the LIS1 gene.

Abstract
BACKGROUND Invasive pulmonary aspergillosis (IPA) remains a life-threatening condition despite systemic antifungal therapy. OBJECTIVES This retrospective analysis investigated whether additional bronchoscopic instillation of amphotericin B (amB) would improve efficacy of antifungal treatment in patients with haematological malignancies suffering from IPA. METHODS Twenty patients (40.6 +/- 14.2 years, 14 male) with preceding chemotherapy, bone marrow or stem cell transplantation complicated by severe IPA who did not respond sufficiently to systemic antifungal therapy were additionally treated by repeated bronchoscopic instillations of amB solution (91 instillations, on average 4.6 +/- 2.2 instillations per patient over a period of 24.1 +/- 21.0 days). Therapeutic response to this combined treatment regimen was monitored by chest X-ray and CT scan. RESULTS The mean infiltration sizes during systemic antifungal therapy alone (mean duration 11.9 +/- 9.9 days) did not change significantly. However, after additional bronchoscopic instillation of amB solution infiltration sizes were reduced significantly (p < 0.05). A total resolution of infiltrates was seen in 3 and a partial reduction in 13 of 20 patients. Mean duration of total antifungal treatment was 50.1 +/- 24.0 days. The mean follow-up period was 34.1 +/- 31.2 months. The IPA-related mortality rate was 18.8% (3 of 16 patients). CONCLUSIONS Additional bronchoscopic instillation of amB may improve the efficacy of systemic antifungal therapy in patients with haematological malignancies complicated by severe IPA. Bronchoscopic instillation of amB should be considered as an additional treatment option in cases with IPA unresponsive to systemic therapy.
