RESUMO

UNLABELLED: Deficiency of vitamin D (25-OHD) is a health problem among prematurely born women and their newborns independently of the geographical location of the country. OBJECTIVES: To study serum levels of vitamin D in patients born before 32 weeks and their newborns at birth. To analyse the socio-demographic factors, complications of pregnancy and their relationship with vitamin D status of women. PATIENTS AND METHODS: The study has been carried out in the University hospital "Maichin dom" Sofia for the period August 2013-January 2014. 35 women who gave birth before 32 gestational week and their 41 newborns with birth weight < 1500g have been investigated. The serum level of vitamin D (25-OH D) in mother-infant pairs at birth and 8 weeks of age in infants has been investigated. The ECLIA method has been used. Serum levels of vit D (25-OHD) have been estimated as sufficient:(> 30 ng/ml), insufficient (21-29ng/ml) and deficient (< 20 ng/ml). RESULTS: At delivery according to their vit D (25- OHD) serum levels 63% of the mothers are defficient /12.61 ± 4.8 ng/ml/, 28.5% are insufficient/26.66 ± 2.59/and only 8.5%/40.4 ± 8.48/sufficient with normal levels of vitamin D. For newborns data are respectively 32%/ 20.08 ± 3.69/-deficient, 49%/27.39 ± 2.70/- insufficient and 19 %- sufficient/41.6 + 10/ There is a positive correlation between mother's and children's serum levels of vitamin D (25- OHD). Statistical significant differences are observed in the levels of vitamin D and the presence of infection and preeclampsia in the mothers. During the period of the study there were no seasonal variations in vit D (25-OHD) serum levels of mother-baby pairs. All newborns received Vit D3 1334 IU/daily from 20th day of age. At eight weeks of age sufficient levels of vitamin D have 70% of the children, but 30% of the newborns remains with inadequate supplementation/27.09 ng/ml/. CONCLUSION: 91.5% of mothers are with insufficient serum levels of vitamin D (25OHD) at birth, and a deficit is present in 63% of all women. Only in 8.5% of the women had normal values. This implies more effective monitoring and vitamin D prophylaxis during pregnancy.

RESUMO

BACKGROUND: The progress in the perinatology improved the survival rate of the infants with extremely low birth weight and gestational age. Among the most immature of them the frequency of bronchopulmonary dysplasia (BPD) remains high.. The use of different diagnostic criteria for BPD makes comparing the results difficult. AIM: To evaluate the frequency of BPD by birth weight and gestational age according to the new diagnostic criteria, and to identify the risk factors for development the disease. METHODS: 563 very low birth weight infants (<1500 g) were admitted to NICU from 01.01.2008 to 30.06.2010. 485 survived more than 28 days and were included in this study. BPD was diagnosed if supplemental 02 for the first 28 days was necessary. 02-requirements at 36 gestational weeks (gw) determine the severity level. RESULTS: 26,8% from the infants were with supplemental 02 in the first 28 d of life, but only the half of them 13,6% were with 02 > 21% at 36 gw (the classical diagnostic criteria for BPD). 10,9% were with moderate BPD, 2,7% - with severe BPD. The frequency of BPD decreased progressively from almost 100% at 23 gw or birth weight < 600 g to single cases after the 31 gw and birth weight > 1200 g. Mild or moderate BPD was more likely if gestational age was > 27 gw. The need for ventilatory support increased from 1,5 (+2,8) days (no-BPD group) to 50,2 (+/-20,1) days (severe BPD), p<0.05. Significant postnatal risk factors for developing BPD were patent ductus arteriosus - diagnosed in 25,4%; pneumothorax - in 3% of the BPD infants, compared with 1,7% and 0,5% among the infants without BPD respectively, p<0. 05. Sepsis and pulmonary hemorrhage were found slightly more frequently in the BPD group too (p>0, 05). The use of antenatal steroids was found to be a protective factor - 45% of the BPD infants had received antenatal steroids compared with 55% of those without BPD (p=0.05). CONCLUSION: According to the new diagnostic criteria, the frequency of BPD was about 2 times higher compared to the classical definition. Main risk factors were found to be ELBW, ELGA; additional risk carried the need for prolonged ventilatory support, patent ductus arteriosus and air leak syndrome.

RESUMO

UNLABELLED: The use of assisted reproduction technologies is undoubtedly successful in the treatment of sterility. However it sets up numerous of issues for the obstetricians and neonatologists. AIMS: To evaluate the incidence, the specific problems and the neonatal outcome of newborns with very low birth weight (VLBW) <1500 g born from pregnancies after in vitro fertilization (IVF). METHODS: The study enrolled all 563 VLBW infants admitted in the NICU of the "Maichin Dom" hospital from 01.01.2008 to 30.06.2010. 119 (21.1%) of them were conceived with assisted reproduction technology (IVF- group), and 444 (78.9%) were conceived naturally (control group). All infants were followed up till their discharge home or death. Poor outcome measures were in hospital neonatal death or morbidities with long term sequels: severe congenital malformations, bronchopulmonary dysplasia, severe brain injuries (intraventricular haemorrhages gr. Ill-IV periventricular leucomalacia), retinopathy of prematurity gr. Ill-V. RESULTS: There were no significant differences in terms of mean birth weight (BW) and gestational age (GA) between the groups (1170 g and 1173 g, 29,8 and 30,0 weeks of gestation respectively). Intrauterine growth retardation (BW of <10 percentile for GA) was observed in 42% in the IVF-group, versus 38.5% (NS) The frequency of the babies from multiple pregnancies was significantly higher in the IVF-group: 88.2% versus 27.5%, and the triplets were 48% versus only 0.9% in the control group. In the IVF-babies more active obstetric approach was carried out: caesarean section in 85% versus 57%, and completed antenatal corticosteroid course in 80% versus 41% in the control group. There were no significant differences of in hospital neonatal mortality rate - 14.3% in the IVF-group versus 14.9%; congenital malformations or severe morbidities at discharge - 22.7% versus 27.5%, discharged in good health - 63% versus 57.6%. CONCLUSIONS: The major problems of VLBW-newborns after IVF result from the higher incidence of multiple pregnancies with their corresponding risks. Nevertheless, strict pregnancy follow-up, more frequently use of antenatal steroids, cesarean delivery such as intensive neonatal resuscitation ensure a clinical outcome and prognosis which do not differ from the naturally conceived VLBW-newborns.

RESUMO

UNLABELLED: AIM AND TASKS: The major gene regulating erythropoietin /EPO/ synthesis is hypoxia induced factor/HIF/. Proceeding from the assumption that the transfusions /HT/ remove hypoxia due to anemia and inactivate HIF, the aim of the study was to show the decreased activity of erythropoiesis after HT MATERIALS AND METHODS: PATIENTS: 40 premature infants <34 g.a. and birth weight < 1400 g with anemia of prematurity. We analyzed: Hb /g/I/, Ht%, Thrx 10(9)/I, Ret%, 24-48 hours and 7-10 days after HT The dynamics of changes of blood lactate /mmol/l/level after HT was used as an indirect index of relative hypoxia/activated HIF/. The changes of Hb /g/l/ and Ht% determined the need of haemotransfusions. RESULTS: After HT along with the increase of Hb from 89, 7+/-10,0 to 119+/-13,3, there was significant decrease in Ret % from 2,4+/-1,1 to 1,4+/-0,5 7-10 day after HT There was also a reduction of Thr from 391,5+/-131,5 to 250, 7+/-57,2 and blood lactate in mmol/l from 2,5+/-1,1 to 1,5+/-0,7. The study showed that 7-10 days after HT the values of Hb and Ht decreased to baseline levels, that required new transfusion. CONCLUSION: Transfusion of packed red blood cells in patients with anemia of prematurity suppresses erythropoiesis, which is demonstrated by the significant reduction in reticulocyte count. The decreased level of blood lactate after HT shows elimination of the relative hypoxia that is required for hypoxia- induced expression of HIF and erythropoietin synthesis.

RESUMO

UNLABELLED: Blood lactate at birth as result of activated anaerobic glycolysis is a marker of perinatal asphyxia. AIM: To evaluate the dynamics of blood lactate, pH and base excess (BE) as a tool for assessing the severity of fetal hypoxia and predicting neonatal outcome. METHODS: 79 neonates (> or = 34 gestational weeks) were included and followed up until discharge: 43 with pathologic fetal hearth rate patterns and/or 1-minute Apgar score < 7 ("asphyxia group"); 36 without obstetric or clinical signs of asphyxia (control group). Samples from umbilical artery (u.a.), capillary blood at 2h and 12-24 h after birth were analyzed for blood lactate, pH and BE. RESULTS: Lactate value (u.a.) was significantly higher (5.3 +/- 3.4 mmol/l), pH and BE were lower (7.29 +/- 0.05 and -14.1 +/- 5.9 mmol/l) in the "asphyxia group" compared to the control group (2.7 +/- 1.2 mmol/l, 7.29 +/- 0.05 and -5.9 +/- 3.3 respectively). The 2 h lactate-values increased significantly in infants with asphyxia (6,.7 +/- 4.7) compared to the controls (3.2 +/- 1.1), the 12-24 h values were reduced in the main group (4.6 +/- 1.5) and without changes in the controls (3.2 +/- 0.88). Values of pH and BE at 2 h and 12-24 h increased progressively in both groups without significant differences between them. Hypoxic-ischemic encephalopathy (HIE) stage II-III was observed in infants with u.a. pH < 7.05, BE < -15 if u.a. lactate was high and progressively increased in next 2 h. CONCLUSIONS: High u.a. lactate values correlate with low pH and BE and is a reliable tool for assessing the severity of fetal asphyxia. Increasing lactate concentration after birth is better predictor of severe HIE.

RESUMO

AIM: The main aim of the trial is to determine the frequency of respiratory distress syndrome / RDS/ and disorders of coagulation in infants of mothers with thrombophilia. MATERIALS AND METHODS: In 51 newborns of mothers with thrombophilia were evaluated the presence of respiratory distress and maternal-fetal infection /MFI/. The children were divided in two groups: Group I--16 newborns of mothers with thrombophilia and Group II--15 healthy children. We analyzed Hb, Ht, Er, Thr, prothrombin index /INR/, activated partial thromboplastin time /aPTT/ in both groups. RESULTS: The analysis of Hb, Ht, Er, Thr showed no evidence of anemia or coagulopathy with platelet consumption. In 64.7% of children was observed respiratory distress syndrome during the first days, 21.5% had severe respiratory distress /RD/, that required intubation and assisted ventilation. Only in 10/19.6%/ children with RDS there were data proving MFI/high CRP and positive microbiological samples/. There was no significant difference in the INR value in Group I/1.5 +/- 0.3/ and group II/1.6 +/- 0.1/. The children of mothers with thrombophilia had significantly more shortened aPTT/35, 1s +/- 4.2/ compared with the control group: aPTT/43.9 +/- 4,4/. CONCLUSION: The high incidence of RDS and shortened aPTT indicate that maternal thrombophilia is a risk factor for thrombosis in newborns. MFI that are accompanied with activated PAI also lead to thrombosis, especially in children in Neonatal Intensive Care Units. These results point out that there should be prevention of other risk factors for thrombosis such as dehydration and placement of central venous catheters.

RESUMO

UNLABELLED: Osteopenia of prematurity is a metabolic bone disease of premature infants with birth weight < 1500 g and gestational age < 32 weeks. Sub-optimal bone matrix, poor skeletal support and an increased risk of fractures characterized the disease. Its importance is determined by relatively high frequency--between 30-70% of infants at risk, multifactorial etiology and impact on early and late morbidity of the newborns. The prevention and treatment of bone disorders are important aspects of the care of preterm babies. OBJECTIVE: To identify of the risk factors, to determine early diagnostic criteria and to create a prevention program for osteopenia in infants with very low and extremely low birth weight. MATERIALS AND METHODS: The prospective study includes 39 preterm babies with birth weight below 1500 gr. and < 32 g. w who were admitted to the NICU from September 2011-January 2012. Bone metabolism was monitored by calcium, phosphate and alkaline phosphatise at 2-weeks intervals. Vitamin D levels of the neonates were registered at birth, and at 8th week. PTH was measured at the second and the 8th weeks. RESULTS: The following biochemical abnormalities were found. Hypophosphatemia in two weeks (P < 1,6 mmol/l), a gradual increase in phosphorus levels and normalization at eight weeks of age. There was a significant positive correlation between 25OHD/phosphorus at eight weeks/r = 0.353/. Significantly elevated levels of parathyroid hormone in eight weeks, correlating with low levels of vitamin D (negative correlation between 25OHD/parathormone r = -0.581). Blood levels of calcium and alkaline phosphatase were in normal limits. IN CONCLUSION: Risk factors for osteopenia are: the low gestational age and low levels of vitamin D at birth. Biochemical markers of osteopenia are: changes in levels of parathyroid hormone, phosphorus and vitamin D at eight weeks of age. Prevention includes: early supplementation of vitamin D in the risk neonates with individual dose adjustment. Upon biochemical evidence of osteopenia treatment should begin in the second week of life with supplementation of phosphorus, and vitamin D 1320 IU/daily and appropriate physiotherapy.

RESUMO

UNLABELLED: Normal foetal growth depends on sufficient mother's vit D intake. Premature birth interrupts vit D and mineral mother-to-foetus transfer and leads to vit D deficiency and disturbs newborn mineral bone metabolism. OBJECTIVES: To determine vit. D plasma levels in mothers and their very low birth weight- (VLBW) newborns and the prevalence of vit D deficiency in this population, to investigate seasonal variation and analyse babies' vit D levels from birth to the 8 postnatal week. PATIENTS AND METHODS: The study has been carried out in the University hospital "Maichin dom" Sofia for the period 09.2011-01.2012 and there have been investigated 32 women and their 39 VLBW infants as a target group. 25-OHD level has been measured in maternal and newborn cord blood samples. The ECLIA method has been used. 25-OHD level has been tested second time at eight weeks of age in 34 infants. According to the maternal vit D levels the patients have been divided into 3 groups: Group. 1--vit D reference range level (> 30 ng/ml); Group. 2--vit D insufficiency (21-29 ng/ml), Group. 3--vit D deficiency (< 20 ng/ml). RESULTS: Low Vit. D levels have been estimated in 62.5% of mothers' group. Nevertheless, only 38.6% of all babies have been Vit. D deficient. In 61.4% of them vit D has been in normal range (32.4-35.7 ng/ml). A significant positive correlation between maternal and infants' vit D level at birth has been established (r = 0.516; p = 0.002). There have been found a significant seasonal dependence of vit D level at birth in the group too: vit D plasma levels have been estimated higher in September-October group compared to those in November-January group. Most of the blood samples in winter months showed lower vit. D levels than the autumn group. At 8 weeks of age 67.6% of the babies have been with vit D insufficiency. There has been a significant positive correlation between 25-OHD levels at birth and at weeks (r = 0.425; p = 0.012). CONCLUSION: Vit. D insufficiency has been found in 62.5% of the mothers at birth. Maternal vit. D deficiency is a significant risk factor for neonatal vit D deficiency. There is a clear seasonal dependency with a significantly lower 25-OHD level in the mothers and their VLBW babies in winter months.

RESUMO

The Turner syndrome, karyotype 45,X0 in the classical form, often remains undiagnosed until significant growth retardation is presented and sexual maturation at the puberty fails to occur. The girls are as a rule with normal IQ. We report a case of an infant of a 24 years mother after two spontaneous abortions and one birth of a normal boy. The newborn girl is with IUGR, after birth we establish edema of the feet, prominent ears and systolic murmur. The echocardiography diagnoses cardiac malformation--bicuspid aortic valve and sub aortic obstruction. The chromosomal analysis shows karyotype 45,X0. We discuss the methods for prenatal and early postnatal diagnosis. In utero and in the neonatal period there are symptoms that make the diagnosis Turner syndrome probable so that chromosomal analysis should be made to confirm it. Looking for other malformations (heart, kidney, endocrine) is necessary. The early diagnosis makes possible the beginning of appropriate hormonal treatment to achieve normal growth and to induce puberty.

RESUMO

OBJECTIVES: The aim of the study is to establish the influence of r-hu-EPO treatment for anemia of prematurity on changes in blood count values and the number of inevitable blood transfusions in premature infants. STUDY DESIGN: The study includes 148 newborn babies--birth weight < or =1400 g, gestational age < or =34 g.w. They were divided in 2 groups: group I--treated with r-hu-EPO 1000 E/kg/week and Fe++ 3-6 mg/kg/day from week 3 after birth; group II--controls, treated only with transfusions of red blood cells. The changes in blood count values (Hb, Ht, Ery, Ret) from day 15-25 until day 60-70 were followed and analyzed, as well as the number of inevitable blood transfusions. RESULTS: A significant increase in Hb and Ht values was established with r-hu-EPO treated babies. At day 60-70 mean values of Hb are: in r-hu-EPO group 111.1 +/- 11.06 g/l; in control group 99.20 +/- 10.77 g/l (p < 0.001). At the end of the period Ht is 32.02 +/- 3.28% in babies treated with r-hu EPO versus 29.10 +/- 2.87% with controls (p < 0.005). Ret count is significantly higher from day 25-30 in r-hu-EPO group (5.16 +/- 3.23%) versus controls (2.75 +/- 1.33%). Mean number of inevitable blood transfusions in r-hu-EPO treated group is significantly lower (2.06 +/- 1.62) versus controls--3.75 +/- 1.95 (p < 0.001). CONCLUSION: r-hu EPO treatment has effect on changes in Hb, Ht, Ret and reduces the number of inevitable blood transfusions for anaemia of prematurity.

RESUMO

High risk newborn babies, admitted and treated at the Intensive care units often have to be started on intravenous nutrition--total or partial. The guidelines which we propose are adapted to the specific needs of the various groups of critically ill newborns--daily intake of liquids and essential nutritional substances according the day of life and the birth weight, as well their variations depending on the clinical condition and the morbidity of the baby.

RESUMO

UNLABELLED: The main cause of anaemia of prematurity is low erythropoietin levels. A few years ago hypoxia-inducible factor/HIF/gene transcriptor was established, regulating not only the synthesis of erythropoietin /EPO/, but also other growth factors as well as enzymes of anaerobic glycolysis, activated by hypoxia. OBJECTIVES: The aim of the study is to establish in clinical practice the role of hypoxia, respectively, activated HIF during treatment with erythropoietin by analyzing variations in hematological values; to examine blood lactate levels as an indicator of activated HIF and anaerobic glycolysis with Hb values 110-120 g/l; to analyze the number and impact of red blood cells transfusions on different categories of babies. STUDY DESIGN; The study includes 112 premature infants born before 34 weeks of gestation and below 1400 g. 90 babies, treated with EPO (700-1000 E/kg weekly dose in 2-3 applications, for 2-4 weeks), values of Hb g/l, Ht%, Ret%, Platelets 109/l were followed and compared. Treated babies were divided in two groups: group I--treatment (starting at Hb below 106 g/l, Ht less than 31%); group II--late prophylaxis (starting at Hb > or = 106 g/l, Ht > or = 31%). Blood lactate was examined in 22 non oxygen dependent premature babies without EPO treatment, with Hb 110-120 g/l, Ht 29-32%. RESULTS: We found that in group II during the first 7-10 days Hb decreases to 105.6 (+/- 9.4) g/l, rising up afterwards to 113.5 (+/-11.0) g/l at day 25-30. Ret reach maximal values at day 15-20 when Hb drops below 110 g/l and Ht below 31%. In group I at day 25-30 of treatment is observed a rise in Hb up to 117.3 (+/-11.3) and of Ht up to 32.7% (+/- 2.6) and no decrease of Hb and Ht values during the first 7-10 days, while Ret rise up to maximal values 6.5% (+/- 3.6) at day 7-10. With Hb levels of 116.4 (+/- 4.6) g/l we found an increase in blood lactate levels up to 2.6 (+/- 0.7) mmol/l as an indicator of relative hypoxia and activated HIF. Mean number of blood transfusions in group I is 3.01(+/- 1.7), versus 2.15 (+/- 1.7) in group II (statistically non-significant). In 29 infants in group II treatment was started at Hb 110-120 g/l and the mean number of red blood cell transfusion is 1.8 (1.5)--statistically significant difference with group I. In 32% from the treated infants we found platelets count rising above 500 x 109/l. CONCLUSIONS: The presence of hypoxia at low levels of Hb and Ht leads to more rapid activation of erythropoiesis. Nevertheless, these babies need more red blood cell transfusions due to clinical symptoms of hypoxia. Normoxia after red blood cell transfusion leads to decrease of reticulocytes count by 30% and platelets by 35% in spite of treatment. The presence of relative hypoxia with Hb 110-120 g/l u Ht 31-32% is optimal for starting treatment with EPO--levels, low enough for activation of HIF and high enough to avoid blood transfusions.

RESUMO

UNLABELLED: Newborn infants with birth weight 1500 g and less (VLBW/ELBW) have higher nutritional needs, but enteral feeding is often insufficient or impossible. Parenteral nutrition (PN) as an important component of intensive care with them minimizes the risk of nutritional deficiency. OBJECTIVE: To evaluate the safety and efficacy of early PN administration in VLBW/ELBW infants. STUDY DESIGN: The prospective study includes 23 newborn babies with birthweight below 1500 g who were admitted to the NICU from 01.03. to 20.04. 2009. With all babies a PN was started from the first day of life with dextrose and amino acid solutions, adding lipid solutions in gradually increasing quantity on the second day. During the first 20 days of life for each baby were calculated on a daily basis the exact quantities of energy and the essential nutritional substances as well as the balance among them. All babies were followed up for weight gain, presence or absence of complications, related with parenteral nutrition as well as for: blood sugar, acid-base status, total serum protein, electrolytes, urea, triglycerides, billirubin, alkaline phosphatase, ASAT ALAT RESULTS: We found that due to the small infusion volumes during the first days, the minimal daily needed nutrition levels are reached at day 4-5. Nutritional intake at day 7-10 in most children is enough for growth. A positive mean weight gain for the whole group 6.6 g/kg/d (SD 6.2) is observed. Negative weight gain during the first 20 days is observed only with two critically ill babies with substantial reduction of infusion volume. In 9 babies a transient increase in urea levels was observed during the first week, 5 babies had an increase in triglycerides as a symptom of bad lipid tolerance. In 7 babies on prolonged total PN an increase in alkaline phosphatase is observed. Conclusions. Early and sufficient PN in newborn babies below 1500 g guarantees the daily intake of energy and essential nutritive substances for adequate growth and is a basic component of intensive therapy. It should be corresponding to the nutritional needs as well as to the clinical condition; matching the severity of complications and carried under strict laboratory control.

RESUMO

UNLABELLED: The illness severity by admission in NICU reflects the intensity of the therapy, the prognosis for the newborn and the hospital costs. Using the CRIB (Clinical Risk Index for Babies) as an objective and easy method for measuring the illness severity in the first 12 h of life allows assessing the risk of death until discharge. AIM: To apply the CRIB for assessing the illness severity and to investigate its prognostic value for life and risk of permanent disabilities among very low birthweight (VLBW) and gestational age (VLGA) infants. METHODS: The study includes the inborn babies in the Specialized Obstetrics & Gynaecology Hospital "Maichin dom" with birthweight < 1500g and gestational age < 32 weeks of gestation, who are admitted in the NICU for 2 periods: I group--250 newborns in the period 01.2002-06.2004 and II group--186 newborns in the period 07.2004-06.2006. The CRIB is estimated based on data collected in the first 12 h of life. An analysis was made about the prognostic value of the CRIB score and the outcome. Criteria for outcome are: the in hospital mortality rate and disabilities such as severe intraventricular hemorrhages (IVH gr. III and IV), chronic lung disease (CLD) and retinopathy of prematurity (ROP). RESULTS: We establish that the CRIB score is significantly higher among the infants who died--12.7%/13% in the I / II period compared with survivors--6.2% / 5.7% (P < 0.001). The mortality rates raise progressively with the CRIB score: among the newborns with CRIB 0-5 they are 2.9% / 2.6% and reaches up to 78.6% / 90% when the CRIB is > 15. The infants with permanent disabilities were with significantly higher CRIB scores too: 11.7 / 11.4% among the infants with IVH III-IV compared to 6.2 / 5.2 without; 9.6 / 10.1 among infants with CLD compared to 5.7 /5.2 without; 10.1 / 10 among infants with ROP compared to 5.5 / 5.1 without. CONCLUSIONS: The CRIB score is useful and easy to apply early and objective prognostic criterion about the risk of in hospital death and permanent disabilities among VLBW newborns. It can be used as a basis for comparing the results of the different NICUs too.

RESUMO

AIM: The aim of the present study is to define criteria for erythropoietin therapy of hyporegeneratory anemia in premature newborns according to hemoglobin (Hb) and hematocrit (Hct) concentration, and reticulocyte count (Ret). MATERIALS AND METHODS: The prospective study includes two groups of 20 newborns with anemia of prematurity, body weight at birth below 1500 grams and gestation age below 33 gestation week. The newborns in the first group have been treated with beta-erythropoietin for four weeks--750-1000 E/kg weekly dose, divided q48h. Hb, Hct and Ret have been monitored and compared with that of control group newborns. The therapy of newborns in the control group consisted of blood transfusions. RESULTS: The hematological parameters in the newborns from the first group have been increased permanently after the first week of therapy, with Ret being most sensitive to the therapy. In the second group of newborns, due to blood transfusions, transient increase of Hb and Hct, and decrease of Ret have been observed in next days after the blood transfusions. CONCLUSIONS: The erythropoietin therapy of hyporegeneratory anemia in preterm newborns leads to rise in Hb, Hct and Ret. The therapy with blood transfusions suppresses erythropoiesis. This leads to decrease in Ret and transient rise in Hb, Hct and erythrocytes. That's why each blood transfusion leads to another one.

RESUMO

The pharmacokinetics of Gentamycin administered to 22 infants intravenously at currently recommended doses (2-2.5 mg every 24 h for infants less than 7 days of life and 28 g.a. and 12 h for infants 32 g.a). The results showed a statistically significant relation between half-life and postconsiptional age and direct correlation between total body clearance and postconsiptional age. These pharmacokinetics data were used to calculate a new dosage schedule for preterm infants. Ondoing therapeutic drug monitoring is essential to tailor the dosage to the individual patient. Gentamycin.

RESUMO

Prematurely born infants with intraventricular haemorrhage (IVH) suffer significant morbidity and mortality, particularly those infants with high grade haemorrhage. The more premature infants have a higher incidence, experiencing more severe IVH. The etiology of IVH is clearly multifactorial. Prevention, both prenatal and postnatal. These include efforts to prevent preterm delivery. Postnatally, the importance of optimal resuscitation and neonatal care practices is stressed, particularly those which minimize cerebral blood flow fluctuation. 130 premature infants of less than 32 weeks gestation with a very low birth weight (VLBW) and extremely low birth weight (ELBW) were studied. They were divided in four groups: group I (n=35) received Indocid; group II (n=42) received Indocid and Phenobarbital; group III (n=53) received Indocid and Phenobarbital; surfactant. These three groups were compare to a reference group (n=45). Newborns from the main group were given Indocid 0.1 mg/kg from 6-12 h of life and during next three days, Phenobarbital 5 mg/kg first five days after delivery and surfactant in the first 4 hours of life according to the protocol provided with the specific surfactant replacement product. Cerebral netrasaund in 24 hours, day 3, 5 and 10 of life and follow up till one year age were performed. We found that IVH/PVH percentage is lowest in newborns from group III, followed by newborns from group II and group I.

RESUMO

Considering the high mortality and serios morbilidy associatent with neonatal infections. A competent diagnostic marker also needs to have reasonably high specificity. Good evidence exists to support the use of CRP measurements in conjunction with other established diagnostic tests (such as a white blood cell (WBC) count with differential and blood culture) to establish or exclude the diagnosis of sepsis in full-term or near-term infants. Sepsis was suspected within the first 3 days after birth in. There were 20% early-onset and 53% late-onset episodes of proven sepsis. CRP had sensitivities of 39.4% and 64.6% for proven or probable sepsis and 35.0% and 61.5% for proven sepsis in early-onset and late-onset episodes, respectively. To compare the clinical informative value of and C-reactive protein (CRP) plasma concentrations in the detection of infection and sepsis and in the assessment of severity of sepsis. PCT is a better marker of sepsis than CRP. The course of PCT shows a closer correlation than that of CRP with the severity of infection and organ dysfunction. Diagnostic markers are useful indicators of neonatal bacterial infections C-reactive protein (CRP), procalcitonin (PCT) Intralevcin 6, 8 are early sensitive markers of infection.

RESUMO

In utero gangrene of an extremity because of an arterial thrombosis is rare. More than 20% of the reported cases concern infants of diabetic mothers (IDM) with poor control of diabetes. Changes in coagulation related to deviation of clotting factors and low plasminogen activity may be the cause. We report a case of an IDM who presented at birth with upper extremity gangrene. The Dopplersonography has shown missing pulsations and thrombosis of a.brachialis sin, which was confirmed after amputation of the arm on the 5th day. The postoperative period was complicated by septicaemia, necrotising enterocolitis and disseminated intravasal coagulation resulting in the baby's death 10 days after birth.
