The effect of pre-eclampsia on coagulation and fibrinolysis in newborns is still under investigation. We have evaluated several coagulation and fibrinolysis parameters in umbilical cord blood of 20 newborns from pre-eclamptic women and of 40 newborns from normotensive women with similar gestational age. Additionally, the presence of factor V Leiden and prothrombin G20210A mutation in cord blood has been assessed. Neonates from pre-eclamptic women exhibited significantly lower birth weight (2.48 +/- 0.92 versus 2.88 +/- 0.68 kg, P < 0.05) and were more frequently admitted to the neonatal intensive care unit (45 versus 20%, P < 0.01) as compared with neonates from normotensive women. Cord blood protein C antigen and activated protein C resistance mean levels were slightly higher in the group of neonates from pre-eclamptic mothers. Fibrinogen levels were lower in this group as compared with control newborns (132.17 +/- 46.97 versus 156.08 +/- 49.58 mg%, P < 0.02), and unrelated to birth weight. No significant differences between cases and controls were found in plasminogen activator inhibitor-1 or tissue plasminogen activator cord blood levels. Heterozygous prothrombin 20210A was found in three newborns from normotensive mothers, whereas no factor V Leiden mutation was found in either group. In conclusion, pre-eclampsia seems to have only mild effects on coagulation and fibrinolytic factors in the cord blood of newborns. Since no excess of common polymorphisms predisposing to thrombosis was found in newborns from pre-eclamptic mothers, it is unlikely that the carriership status of these genetic defects of newborns influences the adverse pregnancy/neonatal outcomes.

The aim of this case-control study was to determine whether unplanned resuscitation using a laryngeal mask airway (LMA) is suitable for neonates delivered by elective cesarean section, a procedure known to carry a risk of inadequate physiological response to birth with a consequent adverse respiratory outcome. During a 3-year period, from January 1998 to December 2000, all newborns delivered by elective cesarean section at term were compared with the next infant born vaginally in the same maternity unit (level III center). The two groups were matched for gestational age >37 weeks. The requirement for resuscitation with positive-pressure ventilation (PPV) using either the LMA or an endotracheal tube (ETT), together with the occurrence of an adverse neonatal outcome, was recorded and analyzed in the cesarean section and vaginal delivery groups. During this time 1,284 at-term elective cesarean sections were performed. 3% (n = 43) of the cesarean section deliveries and 1.4% (n = 18) of the vaginal controls required PPV resuscitation by LMA or ETT, a significant difference (OR 1.26; 95% CI 2.38-5.1; p < 0.01). Of the cesarean section group requiring resuscitation, 30 neonates were managed with the LMA and 13 with the ETT, while in the control vaginal delivery group the numbers were 13 and 5, respectively. LMA use accounted of about 70% of the overall PPV resuscitations and was associated with a successful outcome in 42 of 43 cases. One case was unsuccessfully managed with the LMA, and the ETT subsequently used was effective. Moreover, the probability for the LMA-resuscitated newborns of both cesarean and vaginal groups to have a <5 Apgar score at 1 and 5 min, neonatal intensive care unit admission, and respiratory insufficiency requiring oxygen and intermittent mandatory ventilation was statistically lower than for the ETT group (p < 0.01). In conclusion, infants born by elective cesarean section at term are at increased risk of requiring PPV resuscitation as compared with those born by vaginal delivery. We have shown that about 70% of the neonates who required PPV resuscitation after elective cesarean section and vaginal delivery were arbitrarily treated with LMA by the attending anesthesiologist, without adverse negative respiratory outcome., (Copyright 2004 S.

Unlabelled: Upper gastrointestinal bleeding--UGB-, as a complication, is well studied at intensive care units (ICU), but is less known in non ICU settings., Objectives: To determine incidence and risk factors of this entity at clinical hospitalization., Materials and Methods: A case-control study of patients with gastric ulcer disease diagnosed by endoscopy who presented with melena and hematemesis. Ten controls were taken for each case, matching sex, age and prophylaxis for gastric hemorrhage. Demographic data and other know risks factors were analyzed., Result: We found ten bleeding case among 35070 discharges (incidence: 2.8/10000 discharges). Mortality was not increased but the number of transfusion was higher in the bleeding group. We found an assocciation betwen UGB and systemic inflammatory response syndrome--SIRS-(OR: 9.22 IC 95% 2.98-28.17) and diabetes (OR: 7.8 IC 95% 2.3-26.8). The rest of the factors studied did not rich a statistical significance., Conclusions: UGB during clinical hospitalization is a rare complication that requires an increased staying at hospital and a great number of transfusions. It may be probably associated in a positive way with diabetes and SIRS.

A 66 years female, who was since last year under astenia, arthralgias, pimply lesions in spread plates and tests showing eritrosedimentation over 100 mm, anemi, leucocitosis with neutrofilia, policlonal hypergammaglobulinemia, slight proteinuria and IgE on 900. This patient was sporadically treated with corticoids. When made the medical consult had lost 34lb., was under anorexy, as well as dyspepsia. Hemoglobyn 6.9 gr/dl, leucocytes 20000/mm3, neutrofils at 90%, proteinogram the same as former, with hypoalbuminemia. She was taking prednisona, 16 mg/day. When examined showed depress of conscience, astenia, and dermic lesions already quoted. 4 cm nonpainful right axillary adenopaty adhered to deep planes. Medulogram with increased iron, hyperegenerative. Ganglionar biopsia: linfoid hyperplasic process linked to inmune response. Toracoabdominal tomography with adenomegalia in torax and retroperitoneo. Skin biopsia: neutrofilic vasculitis. The patient suspends the 16 mg of prednisona and fever as well as generalized adenopatias come up. After laying aside other ethiologies, and understanding as Castleman Multicentric disease, it is started to supply prednisona 1 mg/kg of weight with a clinical and biochemical fast and outstanding response. After 7 months it was progressively suspended the esteroids and 60 days later, the process fall back; for that, corticoids are restarted, with a good evolution. The illness of Castleman although it is not very frequent, it should be considered as differential diagnosis in those clinical cases that are accompanied with important general commitment, linphadenopaties and respons to steroid therapy.

Leukemoid reaction in low-birth-weight (LBW) infants is a rare, recently documented phenomenon, implicated in the sequence of multiorgan inflammatory diseases of preterm infants. The aim of the present paper is to establish whether a neonatal leukemoid reaction is related to bronchopulmonary dysplasia (BPD) development in LBW infants. The design was a case-controlled, retrospective study of all premature infants (born 40,000/mm 3. The relation between BPD occurrence and WBC counts was studied by Bayesian analysis, dividing WBC counts in 5 progressive bands of 10,000 WBC/mm 3, starting from <10,000 to >40,000/mm 3. Five of 50 BPD infants studied demonstrated WBC counts >40,000/mm 3, with an incidence of 10%, while no control preterm infants presented neonatal leukemoid reaction; the estimated number difference is statistically significant ( p <0.001). There was no other significant association demonstrated between maternal or neonatal variables and leukemoid reaction, including chorioamnionitis, sepsis, and the use of antenatal steroids. Our findings provide further data for the identification of prematures exposed to pro-inflammatory cytokines in utero; the injury responsible for BPD in a subset of prematures may begin with a transient leukemoid reaction.
