RESUMEN
A disseminated Lactobacillus rhamnosus GG ATCC 53103 infection was suspected in a 6 day-old newborn with intrauterine growth restriction (IUGR) symptoms, treated empirically with antibiotics and given L. rhamnosus GG with the aim of preventing antibiotic-associated gastrointestinal complications. The level of C-reactive protein on day 5 compared with day 2 was increased in spite of negative urine and cerebrospinal fluid cultures. The blood sampled on day 6 was found to be positive for lactobacilli, and the isolate was pre-identified as L. rhamnosus or Lactobacillus casei on day 11. The strain identity was then verified as L. rhamnosus GG through PCR and 16S rRNA sequencing. Genotyping with the rep-PCR and AFLP methods confirmed the 100% genetic similarity for both the strain isolated from patient blood and the probiotic product. The newborn became touch-sensitive, cried a lot, had worsening laboratory test results, and increased inflammation parameters, but no fever was observed. After a further 9 days of antibiotic therapy, blood cultures became negative, and laboratory tests improved on day 25. The patient was discharged from the hospital after 27 days. IUGR with a possible link to L. rhamnosus GG bacteraemia might be a new potential risk group, beside patients with organ failure, immunocompromised status and dysfunctional gut barrier mechanisms, for which safe use of probiotics needs careful attention. Universally accepted or improved guidelines for the safer administration of probiotics in risk groups are urgently needed. This report should not discourage the use of probiotics, but should highlight the need for their careful use in IUGR patients.

Migraine in childhood is relatively common disease. Although clinical practice and scientific publications recognize frequent association of migraine and vestibular disorders, relationships have yet to be well defined. In present study the vestibular function was extensively tested in 20 children suffering from migraine. All the patients underwent complete neurootological examination including tonal threshold audiometry, testing of vestibulo-spinal reflexes--Romberg and Unterberger-Fukuda tests, Dix-Halpike test for BPPV, videonystagmography. On videonystagmography each patient was evaluated regarding: calibration, spontaneous nystagmus, gaze nystagmus, eye tracking test, optokinetic and positional nystagmus, and caloric testing. The same procedure have been performed regarding control group comprised of 15 healthy. All the patients with migraine presented abnormalities in vestibular testing. Analysis of the results showed that: functional state of structures forming both visuo-ocular and vestibulo-ocular structures was altered in all the migraine patients evaluated in the study, pathological findings suggest mainly central localisation of vestibular dysfunction in children suffering from migraine, the number of pathological VNG findings seems not to be correlated with the type of migraine.
