Fish tank granuloma not associated to Mycobacterium marinum but to Microbacterium paraoxydans.

Fish tank granuloma has traditionally been associated with Mycobacterium marinum. We report the case of a 54 old-year woman that worked in a freshwater fish pet store and developed a skin ulcer in a hand finger with a suppurative granuloma secondary to Microbacterium paraoxydans. This is a bacterial fish pathogen, rarely observed in human infections.

Fabrication of Chemofluidic Integrated Circuits by Multi-Material Printing.

Photolithographic patterning of components and integrated circuits based on active polymers for microfluidics is challenging and not always efficient on a laboratory scale using the traditional mask-based fabrication procedures. Here, we present an alternative manufacturing process based on multi-material 3D printing that can be used to print various active polymers in microfluidic structures that act as microvalves on large-area substrates efficiently in terms of processing time and consumption of active materials with a single machine. Based on the examples of two chemofluidic valve types, hydrogel-based closing valves and PEG-based opening valves, the respective printing procedures, essential influencing variables and special features are discussed, and the components are characterized with regard to their properties and tolerances.

Adult long-term health-related quality of life of congenital hydrocephalus patients.

Object: Congenital hydrocephalus has a major impact on the lives of patients and their relatives, as well as their long-term neurological development and social integration. The aim of this study was to assess the self-reported health-related quality of life (HRQOL) of patients after reaching adulthood.

Methods: A total of 31 patients who required CSF shunt treatment for congenital hydrocephalus within the 1st year of life (between 1963 and 1987) agreed to undergo a structured SF-36 self-assessment.

Adult long-term outcome of patients after congenital hydrocephalus shunt therapy.

Introduction: Even though shunt surgery has been an established and widely accepted treatment for congenital hydrocephalus for five decades, long-term follow-up and functional outcome data is rare.

Patients And Methods: Sixty-nine patients were examined after congenital hydrocephalus had been treated between 1971 and 1987 at the Department of Pediatric Surgery (University of Leipzig) within the first 12 months of life. Median age of patients was 32 years (range 25-42 years).
