Abstract
The differentiation of physiological pediatric flat feet and the pathological course as well as adequate initiation of therapeutic options represents a challenge the importance of which should not be underestimated. Fears and worries of parents and their insistence on inducement of therapeutic measures take center stage in the physician-patient relationship. The problem is that there are insufficient data from scientific studies dealing with the conservative treatment of flat feet in children. This paper intends to give a survey of the current status in the literature concerning indications and therapeutic success using insoles in the treatment of flat feet in children.

Abstract
This report is about a married couple who were admitted to hospital suffering from gastrointestinal complaints after eating mushrooms. With the suspicion of poisoning with Amanita phalloides treatment started with elimination of the toxins, symptomatic therapy and specific therapy with silibinin. After quantitative determination of the Amanita toxins the patients were immediately transferred to a university hospital.Poisoning by the death cap mushroom is responsible for acute hepatic and often also renal failure and is accompanied by a high mortality. Clinical symptoms follow a three-phase course with gastrointestinal complaints, an asymptomatic interval and finally the hepatorenal phase. Even in suspected cases of intoxication, treatment should be started by antidote therapy with silibinin.

Abstract
Abnormalities in connectivity are thought to contribute to the symptoms of schizophrenia. Accumulating evidence suggests that antipsychotic medication affects both subcortical and cortical grey and white matter volumes. The goal of this study was to investigate the effects of antipsychotic medication on two white matter tracts: a subcortical-cortical tract, the anterior and posterior limbs of the internal capsule; and a cortical-cortical tract, the corpus callosum. Magnetic resonance imaging was conducted on 10 chronic schizophrenia patients treated with typical antipsychotics and 20 healthy controls at baseline. Patients were switched to olanzapine and both groups were rescanned after 1 year. At baseline, the volume of the anterior limb of the internal capsule was 24% smaller in typical-treated patients than controls (p = 0.009). Patients treated with greater amounts of chlorpromazine-equivalent daily dosage had smaller anterior internal capsule volumes at baseline (r = -0.65, p = 0.04). At follow-up, after being switched to olanzapine, there were no significant differences between patients and controls. Patients with schizophrenia had a significant 25% increase in anterior internal capsule volume from baseline to follow-up compared with controls (p = 0.04). These effects were most prominent in the anterior limb of the internal capsule, which consists of fronto-thalamic pathways, and were not statistically significant in the posterior limb of the internal capsule or corpus callosum. Olanzapine may be effective in normalizing fronto-thalamic structural connectivity in schizophrenia.

Abstract
Ochronosis is a manifestation of the rare disease alkaptonuria. The most common presentations include pain in the lumbar spine region starting during the 3rd decade, spreading over the large joints. There exists no curative therapy for the disease at the moment. In the long-term the patients will be dependent on total joint arthroplasty.

Abstract
Epidemiological studies establish a link between Type 2 diabetes (T2DM) and Alzheimer's disease (AD), both leading causes of morbidity and mortality in the elderly. These diseases also share clinical and biochemical features suggesting common pathogenic mechanisms. Specifically, both are amyloidoses as they are characterized by fibrillar protein aggregates - amylin in T2DM pancreatic islets, and beta-amyloid (Abeta) and neurofibrillary tangles (NFTs) in AD brain. Amylin aggregation is associated with pancreatic beta-cell loss, and Abeta and NFT formation with neuronal cell loss. We discuss the possibility that amylin and Abeta exert their toxicity by similar mechanisms, with components of the pathocascades shared, and that therapies based on amyloidogenic properties are beneficial for both T2DM and AD.

Abstract
A case report of a metastatic caused loosening of a total hip arthroplasty one year after primary implantation is presented. A primary cancer was unknown at surgery. Due to suspected low-grade infection, a revision surgery was performed and the diagnosis of a metastatically caused loosening could be made. A bronchial carcinoma was identified as primary cancer. In spite of the rare incidence of the described metastatic loosening, the significance of a differential diagnostic strategy and the importance of a histological examination in revision surgery is depicted.

Abstract
A molecular cytogenetic study was performed on 48 infertile patients who were identified as carriers of balanced translocations (40 cases), inversions (6 cases) or insertions (2 cases) by means of banding cytogenetics. Cases with a Robertsonian translocation or pericentric inversion 2 or 9 were not included. In summary, 100 break-events occurred in these patients, and 90 different chromosomal regions were involved. Thus, this study confirmed the presence of abnormal karyotypes in a subgroup of patients seeking infertility treatment. Breaks were demonstrated to appear preferentially in GTG-light bands in these patients. Furthermore, the observed breakpoints were associated with genomic regions prone to instability due to the presence of segmental duplications. Nonetheless, further detailed molecular analysis will be necessary in the future to characterize the mechanisms and genetic basis for this phenomenon.

Abstract
AIM To compare ultrasound imaging to the anatomy of the acromioclavicular joint. METHODS 13 cadaveric acromioclavicular joints were examined by ultrasound (11 MHz linear array transducer) to determine the limits of the joint capsule and the width of the joint space. The results were compared to macroscopic sections. RESULTS Anatomical variations were observed. The joint space of one specimen was completely filled by fibrous tissue, leaving 12 specimens for a complete study. A hypoechoic meniscoid disc was attached to the superior joint capsule, resulting in a convex curvature of the cranial part. The mean sonographic width of the joint space was 3.9 mm +/- 1.7 mm standard deviation (SD). The mean distance of the joint capsule from the articular bone rim of the clavicle, the acromion, and from the middle of the joint space was 1.1 +/- 1.0 mm, 1.3 +/- 0.7 mm, and 2.1 +/- 0.9 mm, respectively. The distance from the joint space to the capsular insertion on the clavicle and on the acromion was 4.4 +/- 1.4 mm and 5.3 +/- 2 mm, respectively. The mean difference between ultrasound and anatomical measurements in the vertical (cranio-caudal) plane was 0.5 +/- 0.5 mm (SD), whereas the mean difference between measurements in the horinzontal (medio-lateral) plane was 1.3 +/- 1.1 mm (SD). CONCLUSION Due to low cost, safety and wide availability, sonography is suited for the evaluation of the acromioclavicular joint. However, when interpreting the results, errors in measuring, limitations in resolution of the system used, and the anatomy of the acromioclavicular joint and its anatomical variants have to be taken into consideration.

Abstract
The neuropathological hallmark shared between Alzheimer's disease (AD) and familial frontotemporal dementia (FTDP-17) are neurofibrillary tangles (NFT) which are composed of filamentous aggregates of the microtubule-associated protein tau. Their formation has been reproduced in transgenic mice, which express the FTDP-17-associated mutation P301L of tau. In these mice, tau aggregates are found in many brain areas including the hippocampus and the amygdala, both of which are characterized by NFT formation in AD. Previous studies using an amygdala-specific test battery revealed an increase in exploratory behavior and an accelerated extinction of conditioned taste aversion in these mice. Here, we assessed P301L mice in behavioral tests known to depend on an intact hippocampus. Morris water maze and Y-maze revealed intact spatial working memory but impairment in spatial reference memory at 6 and 11 months of age. In addition, a modest disinhibition of exploratory behavior at 6 months of age was confirmed in the open field and the elevated O-maze and was more pronounced during aging.

Abstract
Adrenomedullin (AM) levels are elevated in cardiovascular disease, but little is known of the role of specific receptor components. AM acts via the calcitonin receptor-like receptor (CLR) interacting with a receptor-activity–modifying protein (RAMP). The AM
1
receptor is composed of CLR and RAMP2, and the calcitonin gene–related peptide (CGRP) receptor of CLR and RAMP1, as determined by molecular and cell-based analysis. This study examines the relevance of RAMP2 in vivo. Transgenic (TG) mice that overexpress RAMP2 in smooth muscle were generated. The role of RAMP2 in the regulation of blood pressure and in vascular function was investigated. Basal blood pressure, acute angiotensin II–raised blood pressure, and cardiovascular properties were similar in wild-type (WT) and TG mice. However, the hypotensive effect of IV AM, unlike CGRP, was enhanced in TG mice (
P
<0.05), whereas a negative inotropic action was excluded by left-ventricular pressure–volume analysis. In aorta relaxation studies, TG vessels responded in a more sensitive manner to AM (EC
50
, 8.0±1.5 nmol/L) than WT (EC
50
, 17.9±3.6 nmol/L). These responses were attenuated by the AM receptor antagonist, AM
22-52
, such that residual responses were identical in all mice. Remaining relaxations were further inhibited by CGRP receptor antagonists, although neither affected AM responses when given alone. Mesenteric and cutaneous resistance vessels were also more sensitive to AM in TG than WT mice. Thus RAMP2 plays a key role in the sensitivity and potency of AM-induced hypotensive responses via the AM
1
receptor, providing evidence that this receptor is a selective target for novel therapeutic approaches.

Abstract
Preiser's disease--first described by Preiser in 1910--presents the rare avascular necrosis of the carpal scaphoid. There is no consensus with regard to cause and therapeutic procedure to this day. The initially postulated idiopathic origin of the disease is controversial and rare. It is mainly caused by trauma or repetitive microtrauma, but can also occur as a complication of drug therapy. The rare occurrence of necrosis of the carpal scaphoid following chemotherapy is presented. The treatment was resection of the scaphoid and mediocarpal arthrodesis. Clinical appearance, diagnostic work-up, and therapy of the disease are discussed.

Abstract
INTRODUCTION Ultrasound is useful in detecting acromioclavicular pathologies in cases of trauma, inflammations and degenerative changes in sports medicine. Many studies compare joint space and capsular dimensions of symptomatic and asymptomatic patients. However, no study has examined the reproducibility and reliability of these measurements. The aim of this study was to evaluate the reliability of ultrasonographic measurements in assessing the acromioclavicular joint. MATERIALS AND METHODS 27 acromioclavicular joints of 15 healthy subjects were examined by T1 weighted magnetic resonance imaging (MRI) to determine the normal limits of joint space (a) and joint capsule (b). These measurements were compared to standardised ultrasonographic (11 Mhz) measurements, which were repeated three times. RESULTS The mean difference between MRI and ultrasound measurements was 1.5 +/- 1.3 mm and 1.3 +/- 1.2 mm for distance a and b, respectively. Reproducibility of ultrasonographic measurements was high with a mean standard deviation of 0.3 +/- 0.2 mm and 0.4 +/- 0.3 mm for distance a and b, respectively. CONCLUSION Due to low costs, safety and wide availability ultrasonography is suited for the evaluation of the acromiocalvicular joint. However, when interpreting the results measurement errors, limitations in resolution of the system used, and the anatomy of the acromioclavicular joint and its anatomic variants have to be taken into consideration.

Abstract
Alzheimer's disease (AD) is a devastating neurodegenerative disease that affects more than 15 million people worldwide. Within the next generation, these numbers will more than double. To assist in the elucidation of pathogenic mechanisms of AD and related disorders, such as frontotemporal dementia (FTDP-17), genetically modified mice, flies, fish and worms were developed, which reproduce aspects of the human histopathology, such as beta-amyloid-containing plaques and tau-containing neurofibrillary tangles (NFT). In mice, the tau pathology caused selective behavioral impairment, depending on the distribution of the tau aggregates in the brain. Beta-amyloid induced an increase in the numbers of NFT, whereas the opposite was not observed in mice. In beta-amyloid-producing transgenic mice, memory impairment was associated with increased levels of beta-amyloid. Active and passive beta-amyloid-directed immunization caused the removal of beta-amyloid plaques and restored memory functions. These findings have since been translated to human therapy. This review aims to discuss the suitability and limitations of the various animal models and their contribution to an understanding of the pathophysiology of AD and related disorders.
