Respiratory syncytial virus (RSV) lower respiratory tract infections are considered to be a serious disease in centres such as the Sophia Children's Hospital (Rotterdam, the Netherlands), but as more benign infections in others such as the Geneva Children's Hospital (Switzerland). To assess the clinical severity of RSV infections at the two sites, 151 infants primarily admitted with a virologically confirmed RSV infection were studied prospectively (1994-5) and retrospectively (1993-4) (55 infants in Geneva and 96 in Rotterdam). Parameters of RSV morbidity which were more severe in Rotterdam during the two winter seasons were apnoea (1.8 v 23.9%), the rate of admission to the intensive care unit (3.6 v 28.1%), mechanical ventilation (0 v 7.3%), and length of stay in hospital (6.8 v 9.1 days). In Geneva higher respiratory rates (59.2 v 51.2), more wheezing (65.5 v 28.8%), and more retractions (81.8 v 63.3%) were recorded. Fewer infants younger than 4 months (54.9 v 68.7%), but more breast fed infants (94.1 v 38.5%), were admitted in Geneva, although the morbidity parameters remained different after correction for these two variables in multivariate analyses. Thus unidentified local factors influence the pattern and severity of RSV infection and may affect the results of multicentre prophylactic and therapeutic studies. [ABSTRACT FROM AUTHOR]

A young man presented with recent-onset non-specific symptoms like headache, sleepiness and weight loss, interfering with normal daily life. Physical and biochemical irregularities were absent. Because extensive examination by neurologist and psychiatrist including brain imaging did not reveal any clues, the complaints were initially considered psychosomatic. As the symptoms deteriorated with ongoing weight loss, the patient was re-admitted to the hospital. Again, extensive additional investigation did not reveal any abnormalities. Because of previous exposition to the woods Lyme serology was determined. Surprisingly, it appeared to be a remarkable presentation of acute Lyme neuroborreliosis which was successfully treated with ceftriaxon. Clinicians must be aware of the fact that this severe illness can present without any typical symptoms. [ABSTRACT FROM AUTHOR]
