IntroductionRespiratory failure is a life threatening complication of Guillain Barré syndrome (GBS). There is no consensus on the specific treatment for this subset of children with GBS.MethodsThis was a prospective randomized study to compare the outcome of intravenous immunoglobulin (IVIG) and plasma exchange (PE) treatment in children with GBS requiring mechanical ventilation. Forty-one children with GBS requiring endotracheal mechanical ventilation (MV) within 14 days from disease onset were included. The ages of the children ranged from 49 to 143 months.Randomly, 20 children received a five-day course of IVIG (0.4 g/kg/day) and 21 children received a five-day course of one volume PE daily. Lumbar puncture (LP) was performed in 36 patients (18 in each group).ResultsBoth groups had comparable age (p = 0.764), weight (p = 0.764), duration of illness prior to MV (p = 0.854), preceding diarrhea (p = 0.751), cranial nerve involvement (p = 0.756), muscle power using Medical Research Council (MRC) sum score (p = 0.266) and cerebrospinal fluid (CSF) protein (p = 0.606).Children in the PE group had a shorter period of MV (median 11 days, IQR 11.0 to 13.0) compared to IVIG group (median 13 days, IQR 11.3 to 14.5) with p = 0.037.Those in the PE group had a tendency for a shorter Pediatric Intensive Care Unit (PICU) stay (p = 0.094).A total of 20/21 (95.2%) and 18/20 (90%) children in the PE and IVIG groups respectively could walk unaided within four weeks after PICU discharge (p = 0.606).There was a negative correlation between CSF protein and duration of mechanical ventilation in the PE group (p = 0.037), but not in the IVIG group (p = 0.132).ConclusionsIn children with GBS requiring MV, PE is superior to IVIG regarding the duration of MV but not PICU stay or the short term neurological outcome.The negative correlation between CSF protein values and duration of MV in PE group requires further evaluation of its clinical usefulness.Trial RegistrationClinicaltrials.gov Identifier NCT01306578

In utero exposure to chemotherapy during the second and third trimesters of pregnancy carries minimal morbidity to the unborn fetus.

In children with DR-HD, NS is a safe rehydration fluid with a satisfactory rate of Na(+) drop and relatively low incidence of morbidity and mortality. Judicious use of IVE should be exerted and closer monitoring should be guaranteed for children requiring large volumes for IVE and for those showing rapid initial drop of serum Na(+) to avoid neurological complications and poor outcome.

The aim of the study is to characterize markers of apoptosis in children with acute lymphoblastic leukemia (ALL) in relation to treatment outcome of the disease. The study was performed on 34 children with ALL and 39 healthy children as a control group. Apoptosis was assessed by cell morphology; DNA fragmentation; ELISA and RT-PCR for CD95, CD95L, BcL-2 and nuclear factor-kappa B (NF-kappaB); and flow cytometry for CD95, CD40, CD49d and CD11a. Apoptosis was significantly lower in patients than controls. Apoptosis detected by CD95 ligand was significantly lower in cases with no remission after treatment than those who achieved remission. Anti-apoptotic factors: CD40, BcL-2, and NF-kappaB were all found to be higher in cases than controls and in cases with no remission than those achieved remission. CD49d was significantly lower in cases than controls, and significantly lower in cases with who did not achieve remission. CD11a levels were similar in the various groups. Delayed apoptosis of ALL cells is genetically controlled either directly or indirectly by a network of oncogenes and tumor suppressor genes. CD40 appeared to stimulate both T and B lineage and is considered the most potent influencer and predictor of resistance to therapy. Inhibitors for the activity of CD40, Bcl-2 and NF-kappaB as well as stimulants to CD95 could have a potential therapeutic benefit.
