  1. Physiological leucocytosis is common in neonates. Leukemoid reaction is defined as a variable degree of leucocytosis with immature precursors, similar to that occurring in leukaemia but because of other causes. Leukemoid reactions are well-recognised in the neonatal intensive care unit population and are associated with antenatal corticosteroids, Down's syndrome, chorioamnionitis, funisitis and perinatal infections. However, extreme hyperleucocytosis, exceeding a white blood cell count of 100×109/l is rare. In the 7-year period from 2005 to 2012 three premature infants in our hospital presented with extreme hyperleucocytosis. Since there were no signs of neonatal leukaemia, transient myeloid disorder or leucocyte adhesion defect, a leukemoid reaction owing to antenatal corticosteroids, chorioamnionitis and funisitis was diagnosed. No obvious complications of hyperleucocytosis were observed. Therapy was not necessary and the leucocytes normalised spontaneously. In other hand, should consider bdp. https://pediatrics.aappublications.org/content/pediatrics/116/1/e43.full.pdf
  2. Hello. I'm agree, it's a very interesting case to learn so much. Caput medusae is a rare neonatal finding. • Primary or secondary Budd-Chiari syndrome should be excluded in the neonatal period. • In contrast to adults with caput medusae from portal hypertension, this collateral abdominal circulation can be a benign variant. • If cardiac or venous malformations are ruled out, an expectant approach is indicated because the collateral veins will gradually involute in the first weeks after birth without sequelae. neoreview.soares2020.pdf
  3. hi: I completely agree with your arguments. and I am always asking myself and repeating the same questions of: where does the medicine go? in which immature musculature is it absorbed? for example.
  4. at the past year (2009 of course) we treat with laser or crytherapy almoust 100 premies with ROP stage 2 or 3 or plus disease or threshold, and yes we use avastin in 10 patients with ROP resistant to therapy, only 5 patients wet well... i think avastin therapy is promisourius antimonoclonal therapy but we need to study more... i sugest you: 1) Intravitreal bevacizumab for post laser anterior segment ischemia in aggressive posterior ROP.

RETINA, THE JOURNAL OF RETINAL AND VITREOUS DISEASES 2009, 29(4): 562-568. 6) Our Experience After 1765 Intravitreal Injections of Bevacizumab: The Importance of Being Part of a Developing Story. Seminars in Ophthalmology, 22:109–125, 2007. 7) INTRAVITREAL INJECTION OF BEVACIZUMAB (AVASTIN) FOR TREATMENT OF STAGE 3 RETINOPATHY OF PREMATURITY IN ZONE I OR POSTERIOR ZONE II. RETINA 28:831–838, 2008. 8) Efficacy of intravitreal injection of bevacizumab for severe retinopathy of prematurity: a pilot study. Br. J.

  5. some times it happens, but i am agree with the "work up sepsis"
  6. In my oppinion, i prescribe antibiotics, prothrombin time and parcial tromboplastyn time correction, also Na and K deficiencys, albuminum transfusion depends off the plasma levels. Usually, i don't recommend ETT because those babies has a vascular and perfusion stroke, and i try to shared this paper... STATE-OF-THE-ART Sclerema neonatorum: a review of nomenclature, clinical presentation, histological features, differential diagnoses and management. Journal of Perinatology (2008) 28, 453–460
  7. Hi, i from Guatemala, Central America, i work at Roosevelt Hospital (it's a pubblic institution), we attend about 70 newborns in NICU, and yes i speak spanish

  9. Hi, i don't miss this conference, i will stay at the marriot wardman park hotel, maybe we have a 99nicu meeting
  10. do you have any experience about the use of intravitreal injection of bevacizumab to treat ROP?
  11. we have similar problem with klebsiella pneumoniae resistant to imipenem "in vivo" but sensitive to meropenem "in vivo" and "in vitro", because it's producer a methaloenzymes
  12. do you have any experience about intravitreal avastin for ROP?
  13. do you have a guideline to lasser treatment in NICU? about sedation, turn off the lights, etc.
