    Notes: Abstract Diagnosis of neuroborreliosis is often difficult since history and clinical presentation may be non-specific and serological tests may initially be negative. We therefore tested the polymerase chain reaction (PCR) for the detection of borrelial sequences in CSF and urine samples of consecutive children with neuroborreliosis seen in a single summer season. Four of eight children were negative in serum for antibodies toBorrelia burgdorferi. Two of eight children were PCR-positive in CSF and one other child was positive in urine. In two out of four children PCR was the only laboratory test confirming the clinical diagnosis. All children recovered after treatment with third generation cephalosporins. When seven of eight children were re-examined 6 months later all were healthy and antibodies toB. burgdorferi were detected in their serum. PCR may assist the paediatrician in establishing a diagnosis of neuroborreliosis; however, a negative result does not rule out neuroborreliosis. PCR is an adjunct, but no substitute for clinical judgement and serology.

    Notes: Abstract We report on a diode-laser-pumped cw Nd: YAG laser operating at a power level of 150 W. By using a transverse pump geometry, the radiation of 54 diode lasers with an output power of 10 W each is coupled into a Nd:YAG rod. In multimode operation, an optical slope efficiency of 32% and an optical to optical efficiency of 29% are obtained. In TEM00 operation, an output power of more than 30 W is realized with an optical to optical efficiency of 10%.
