Abstract
Human hantavirus (serotype Puumala) infections are prevalent throughout Europe. The bank vole is the main reservoir of the Puumala virus (PUUV). Between 2001 and 2006, the annual incidences in Germany ranged from 0.1 to 0.5 per 100,000 inhabitants. About half of the cases were reported from the state of Baden-Württemberg (BW) in southwest Germany. In 2007, 1,089 PUUV infections were reported from BW. This reflects an incidence of 10.1:100,000, which is more than 11 times higher than the mean incidence of the previous 6 years. Spatial analysis highlights incidences up to 90:100,000 in the most affected district. The winter season 2006/2007 showed an all time high in reported mean temperature. The previous summer and autumn led to a beech mast year, resulting in favourable feed conditions for bank voles in the winter season 2006/2007. The causes of the observed increase in PUUV infections in 2007 cannot be restricted to known cycles in the bank vole population. Favourable feed conditions, a mild winter and an early onset of spring may have influenced bank vole population size as well as human exposure to infectious rodent excretions. Further epidemiologic studies are necessary to better understand the interaction between environmental factors, occurrence of Puumala virus in bank voles and the risk for human disease.

Abstract
INTRODUCTION The optical coherence tomography (OCT) Visante provides easy, high-resolution observation free of contact with the cornea and anterior segment. We present the progression of a neurotrophic corneal ulcer treated with amniotic membrane grafts studied with this system. METHODS A 71-year-old patient with facial nerve paresis secondary to vestibular schwannoma surgery presented with a neurotrophic perforated corneal ulcer. Since medical treatment had failed, we performed an amniotic membrane graft. The OCT Visante was used for follow-up for 2 months. RESULTS Progression was slow but the perforation eventually closed. Cicatrization of the corneal ulcer was followed with the OCT Visante to document the healing process and corneal thickness. CONCLUSION Optical coherence tomography Visante provides easy visualization and high-resolution documentation with no contact with the healing corneal ulcerations.

Abstract
The spallation of 56Fe in collisions with hydrogen at 1A GeV has been studied in inverse kinematics with the large-aperture setup SPALADIN at GSI. Coincidences of residues with low-center-of-mass kinetic energy light particles and fragments have been measured allowing the decomposition of the total reaction cross section into the different possible deexcitation channels. Detailed information on the evolution of these deexcitation channels with excitation energy has also been obtained. The comparison of the data with predictions of several deexcitation models coupled to the INCL4 intranuclear cascade model shows that only GEMINI can reasonably account for the bulk of collected results, indicating that in a light system with no compression and little angular momentum, multifragmentation might not be necessary to explain the data.

Abstract
Bronchoscopy is the most important diagnostic procedure for the work-up of central bronchial processes and parenchymal lung diseases, such as lung cancer, pneumonias or diffuse lung diseases. Recent progress - ultrasound, navigation systems or ultrathin bronchoscopes - was made to achieve a better yield in the diagnosis of peripheral and peribronchial lesions. Bronchial recanalisation by thermal ablation or stenting is mainly performed with rigid instruments; these procedures as well as brachytherapy in local anaesthesia should be restricted to specialized centers. If pleuracentesis does not provide the etiology of pleural effusion, thoracoscopy in local anaesthesia is the method of choice. The procedure does not only provide a definite diagnosis for almost all of the patients, it also allows the immediate option for talcum poudrage in case of pleural malignancy.

Abstract
Hemodialysis patients develop metabolic acidosis due to their impaired excretion of daily produced protons (H+). The following report will show a rare case of severe metabolic alkalosis (predialysis pH 7.52, base excess (BE) +17) in a hemodialysis woman caused by self-provoked upper gastrointestinal H+ losses based on an eating disorder. Treatment with a proton pump inhibitor resulted in the normalization of acid/base homeostasis (predialysis pH 7.40, BE +1.6).

Abstract
The idiom renal osteodystrophy (ROD) represents a heterogeneous pattern of bone disturbances caused by chronic renal insufficiency and concomitant diseases. For the clinical decision of therapy it is most important to differentiate between high and low or adynamic turnover ROD because the therapeutically consequences of these two ends of the ROD spectrum are fundamentally different. Bone histology remains the gold standard for the exact classification of ROD. Serological markers of bone metabolism are not suited for the accurate nomenclature of ROD but are useful for the sequential follow up of ROD after a clear diagnosis has been made. Similarly, radiological diagnosis of ROD using dual energy X-ray absorptiometry (DEXA) or quantitative computer tomography scan (q-CT) is inaccurate and thus more suited for the routine follow up of established disease. Besides mineralization, bone strength and the rate of fractures are strongly determined by the architecture of the bone matrix. This information, however, is also only available on bone biopsy sections and cannot be estimated by non-invasive diagnostic methods. In summary, bone biopsy should be used more liberally for correct classification of bone disease. The sequential follow up and guidance of therapy success can be performed by non-invasive procedures such as biochemical bone marker determination in blood. X-ray imaging and densitometry is suitable only for sequential evaluation of osteoporosis.

Abstract
Background Lurcher mice suffer from a complete Purkinje cell (PC) loss in the first four postnatal weeks. Parallel to this degeneration, GABAergic synapses in the deep cerebellar nuclei (DCN), the major recipient of the inhibitory PC projection, increase synaptic conductance. Here, we further investigated this phenomenon, using real-time RT-PCR to assess GABAA receptor subunit gene expression during PC degeneration. Results We observed a specific reduction in γ2 subunit gene expression, while α1–5, β1–2, γ1,3 and δ subunits were unaffected. We made two further specific findings. First, the difference in gene expression was shown in tissue from DCN only. Neither the hippocampus nor coronal sections through the forebrain showed such effects. Furthermore, the involvement of different levels of corticosterone, a possible humeral trigger for differences in gene expression, could be excluded. Second, like the known potentiation of GABAergic synapses, the γ2 down-regulation was present only after the onset of degeneration at p14. The difference in γ2 mRNA expression, however, appeared transient, since it was no longer detectable in adult Lurcher mice. Conclusion In conclusion, the down-regulation of γ2 subunits may be related to differences in synaptic efficacy and, as such, may reflect the initial phase of adaptive responses of DCN tissue to massive GABAergic deafferentation. Its transient course, however, does not support the idea that modulations in GABAergic transmission are at the basis of the well-known DCN-based functional benefit of Lurcher mice present throughout their life.

Abstract
OBJECTIVE The intercycle FSH signal that initiates follicular recruitment and marks the functional onset of the menstrual cycle is of small amplitude and while it commonly occurs on cycle day 3, this often varies. Hence, its identification and measurement in serum (sFSH) requires serial daily samplings. We attempted to determine whether urine measurements of FSH (uFSH) could offer a non-invasive alternative, using a model where the intercycle FSH signal is controlled by timely use of exogenous E2. PATIENTS AND METHODS Pilot prospective trial in 21 infertile women having received E2, from day 25 of the previous cycle until the 1st Friday after menses. Blood and first void urine samples were collected, starting on the last day of E2 (baseline) for assessing FSH and creatinin. A sonogram was performed for identification of maturing follicles (>12 mm). RESULTS uFSH and uFSH/Cr showed good correlation with sFSH (R = 0.52 and 0.63, P < 0.0001 and P < 0.0001, respectively). In 15/21 patients who had an intercycle sFSH elevation, this was confirmed by uFSH elevation, both occurring within 2-4 days after stopping E2. In all these women, the sonogram showed evidence of impending ovulation. The amplitude of the uFSH signal was on average 3 times higher than its sFSH counterpart. In 6/21 women, no intercycle FSH elevation was detected and no ovulation occurred. DISCUSSION AND CONCLUSION Our results show that the intercycle FSH signal can easily be identified and measured in urine. This novel approach permits more precise assessments of ovarian physiology than with blood measurements.

Abstract
Isotopic effects in the fragmentation of excited target residues following collisions of 12C on (112,124)Sn at incident energies of 300 and 600 MeV per nucleon were studied with the INDRA 4pi detector. The measured yield ratios for light particles and fragments with atomic number Z < or = 5 obey the exponential law of isotopic scaling. The deduced scaling parameters decrease strongly with increasing centrality to values smaller than 50% of those obtained for the peripheral event groups. Symmetry-term coefficients, deduced from these data within the statistical description of isotopic scaling, are near gamma = 25 MeV for peripheral and gamma < 15 MeV for central collisions.

Abstract
BACKGROUND Given the encouraging results on early restenosis rate with drug-eluting coronary stents, both safety and 6 months outcomes of PCI with sirolimus-eluting stents (SES) in acute myocardial infarction are scarce. METHODS AND RESULTS Fifty consecutive patients with acute myocardial infarction were subjected to acute PCI with SES and compared to 50 matched control patients who received a bare metal stent (BMS). All patients were followed over 6 months; in addition repeat angiography was obtained in 88.0% of SES and 92.0% of BMS patients. As a result of matching both groups were similar with regard to demographic, clinical, and infarction characteristics, as well as procedural data and adjunctive medication. SES diameter was 3.0 +/- 0.1 versus 3.3 +/- 0.5 mm with BMS, while the length of stented segment was 24 +/- 11 mm with SES versus 16 +/- 8 mm with BMS (p<0.05). No subacute stent thrombosis occurred in either group. At 6 months, all-cause mortality was 2.0% with SES, and 4.0% with BMS (n. s.); reinfarction rate was 2.0% in both groups, but binary restenosis rate (4.0 versus 18.0%; p<0.05) and target vessel revascularization (TVR) were improved with SES (2.0 versus 16.0%; p<0.05) resulting in lower MACE rate of 6.0 versus 22.0% with BMS (p<0.05). CONCLUSION Placement of SES with PCI for myocardial infarction is feasible and as safe as BMS; 6-month outcome is superior with SES due to the lower rate of both angiographic restenosis and TVR.
