The rivastigmine patch is the first transdermal treatment for Alzheimer disease (AD). By providing continuous delivery of drug into bloodstream over 24 hours, may offer benefits superior to those oral administration. This study compared efficacy, safety and tolerability patches with capsules placebo. IDEAL (Investigation transDermal Exelon in ALzheimer's disease) was a 24-week, double-blind, double-dummy, placebo- active-controlled study. Patients AD were randomized placebo or one three...

Eine nach Fujita modifizierte Methode der Uvulopalatopharyngoplastik wird mit 17 Operationsskizzen ausführlich geschildert. Ohne die Velummuskulatur zu tangieren, nur überschüssige Schleimhaut des Velums und Uvula reseziert. Auch Musculus uvulae weitgehend geschont, so dass keine Komplikationen beim Schluckakt Phonieren beobachtet wurden, wie bei 70 Patienten gezeigt werden konnte. Auf Probleme Intubation von Patienten, wegen chronischer Rhonchopathien zur UPPP kommen, eingegangen. Diese...

Background Musculoskeletal diseases affect 1.71 billion people worldwide, impose a high biopsychosocial burden on patients, and are associated with economic costs. The use of digital health interventions is promising cost-saving approach for the treatment musculoskeletal diseases. As physical exercise best clinical practice in diseases, that provide exercises could have highly positive impact but evidence lacking. Objective This systematic review aims to evaluate patients concerning...

<h3>In Reply.</h3> —We agree with Dr Haan and colleagues that single proton emission computed tomography (SPECT) brain imaging should not be used to estimate dementia severity in Alzheimer's disease (AD). Dementia is a clinical diagnosis, assessments, including cognitive tests, are the appropriate way measure severity. Our report<sup>1</sup>indicated widespread decreases cerebral perfusion, especially parietal region, were characteristic biological correlates of AD. Despite this association,...

The hypotheses that Swedish patients with four or more primary tumours [including at least one cutaneous malignant melanoma (CMM)] harbour an increased number of CDKN2A (formerly p16) germline mutations, and this group show a predisposition to other tumours, e.g. nonmelanoma skin cancer (NMSC), were studied descriptively. So far the mutation 113insArg explains all CDKN2A-associated CMM in ethnic Swedes.All which was CMM, from Southern Regional Tumour Registry, between 1958 1999, included...

Four of five patients with brain metastases from melanoma had increased lofetamine I 123 uptake in the region tumor deposits. A comparison group no clinical or radiologic evidence involvement and 46 47 without malignant but known tumors other histologic types normal decreased iofetamine tumor. An exception was one patient whose metastatic small cell lung cancer to showed focally uptake. These findings suggest that certain such as are capable selectively binding because specific chemical...

Lung scan data from a series of 45 patients receiving thrombolytic therapy were reviewed to determine if any pattern on the pretherapy perfusion lung scans could be identified that predicted response therapy. A segmental appearance (complete or nearly complete absence in whole segment very large subsegment) was correlated with amount improvement obtained 24 hours after start As group, had more reduction score than nonsegmental (P less .005). However, correlation between and favorable not...
