Perinatology is a dynamically developing field of medicine. The progress of technology in recent decades has made it possible to recognize birth defects very early, including those which are lethal or genetically determined. In many clinical situations, it is no longer possible to work alone to reach a definitive diagnosis, plan treatment or predict the clinical course of the affected fetus/newborn. There is a need for teamwork, which ensures the proper, early care starting in the fetal period, not only in the delivery room or NICU. This paper discusses the ethical foundations of creating interdisciplinary teams, taking as an example the Interdisciplinary Team for Fetal Malformation at the Institute of Mother and Child in Warsaw, which has been active for 25 years, and presents how it works in practice. On the basis of the clinical cases that are examined, practical guidelines were formulated for both the work of medical teams and the way parents are informed about the clinical situation of their child and about sharing the care after the birth of the child. A document was also proposed with information on prenatal diagnosis, decisions made by the interdisciplinary team regarding the mother and child, as well as the conclusions resulting from discussions with parents.

An abnormal presentation of the central nervous system in a fetus during a screening examination is an indication for extended diagnosis, the aim of which is to explain the character of such an anomaly (a congenital defect, destructive effect of intrauterine infection or abnormality with reasons that are difficult to explain). Knowledge of normal development sequence of the fetal brain, which is discussed in this paper, is the basis for correct interpretation of imaging findings. Together with the increase in survival of preterm neonates, a high risk of early brain damage is still a problem in this extremely immature population. Therefore, imaging examinations become necessary. The paper presents intrauterine and postnatal risk factors of early brain damage as well as classification of such lesions, of hemorrhagic and hypoxic-ischemic etiology. The diagnosis of the cerebellum damage, which is currently believed to be a significant cause of autism, is emphasized. The evolution of lesions over time is also presented. Moreover, the elements of diagnosis important for prognosis are stressed. The standards of imaging examinations of the central nervous system include the schedule of ultrasound examinations and provide indications for extended diagnosis with the use of magnetic resonance imaging.

Aim of Study: 1. prospective record of infections; 2. prevention of nosocomial infections by providing current data about infections, which are significant for making therapeutic decisions., Material and Methods: Recorded infections: early-onset sepsis (congenital), late-onset sepsis (acquired in hospital), necrotising enterocolitis (NEC), pneumonia. Infections were diagnosed and qualified on the basis of definitions of infections based on the National Nosocomial Infections Surveillance (NNIS) criteria, developed by CDC, USA, including modifications of German Neo-KISS programme. Infection control was realised as a part of common research project of "Polish Neonatology Network", appointed by the decision of the Minister of Science and Higher Education no. 669/E-215/BWSN- 0180/2008 dated 20.05.2008 r. The study was conducted by 6 Polish neonatology units, Microbiology Chair of Jagiellonian University Collegium Medicum and Institute of Theoretical and Applied Computer Science. Infants with birth weight lower than 1500 g were qualified for the study., Results: Between 1.01.2009 and 31.12.2009, 910 patients were registered, i.e. 19.1% of VLBW infants born in that period. The conducted analysis showed significant differences between centres in gestational age, birth weight, hospitalisation, use of invasive procedures, antibiotics and parenteral feeding. Cumulative morbidity rate was 68.5% total. Blood infection (sepsis) was the most commonly observed type of infection: 268 cases - 43.1% of all recorded forms of infection. Pneumonia was diagnosed in 242 cases, 38.8% total. NEC constituted 12.7% studied infections (79 cases). Apart from NEC, the risk of other forms of infection differed between centres. Dominant etiologic factor of all infections were Gram-positive cocci, which constituted 565 isolated microorganisms. Among them coagulase-negative staphylococci (CNS) were the most common (41.7%), while Staphylococcus aureus was fourth most frequent etiologic factor of infections (6.3% total)., Conclusions: 1. Introduction of unified definition and criteria for diagnosing infections and the use of morbidity rates enables comparative analysis of epidemiology of infections in neonatal intensive care units. 2. Due to significant differences observed between prophylactic and therapeutic procedures in various units, it is essential to propose Polish recommendations regarding control over etiology of infections and use of invasive procedures, such as intravenous catheters and ventilation. 3. It is essential to undertake action leading to fully rational antibiotic therapy, because overuse of antibiotics leads to bacterial resistance and increases incidence of infections.

Aim: To determine the risk of various forms of infections appearing in very low birth weight newborns (VLBW) during the period of 30 days after surgical treatment in hospitals which have perinatal care departments with neonatal intensive care units that form the Polish Neonatology Surveillance Network (PNSN)., Material and Methods: Continuous prospective monitoring of infections was carried out from January 1st to December 31st 2009 in six neonatal intensive care units which form the Polish Neonatal Surveillance Network. (PNSN). 910 newborns with very low birth weight (VLBW) were included in the study programme. 91 (10%) of this group underwent 118 surgical interventions. 12 newborns needed two or more surgeries. The most common procedure was the closure of persistent ductus artesiosus (PDA) and photocoagulation of vascular damage in the eye fundus., Results: In the period of 30 days after surgery the following were diagnosed: in 3 newborns - necrotizing enterocolitis (NEC), in 22 newborns - sepsis (BSI) and in 54 newborns - pneumonia (PNEU). Symptoms of BSI and PNEU were on average observed on the 10th day after surgical intervention, while in the case of NEC on the 17th day. The highest incidence of infection (148.4%) was observed after PDA closure and in connection with introducing a drain into the pleural cavity through the intercostal space. The incidence of PN EU (37.3%) was twice as high as the incidence of BSI (18.6%). Surgical procedure was a factor significantly increasing the risk of infection and morbidity (RR 2.1, P<001) In our investigations there was no case of the local infection of a surgical site. 11 newborns died (mortality was 12.1%). The most common bacterial strains found in our investigation were coagulase-negative Staphylococcus and Escherichia Coli., Conclusions: Taking into consideration the fact that surgical procedure in VLBW-newborns significantly increases the risk of pneumonia and to a minor degree the risk of NEC and BSI, further detailed investigation in the field of perisurgical epidemiology is needed in order to elaborate a more deeply oriented and more effective strategy of infection prevention in the group of VLBW newborns.

Aim: The study presents the results of the analysis of antibiotic consumption and its direct costs in selected neonatal units., Material and Methods: Data were collected retrospectively (the year 2007) in five hospitals, during the pilot phase of the Polish Neonatal Network . Antibiotic consumption was assessed using the Defined Daily Dose (DDD). The costs were assessed as the costs of purchase of one DDD., Results: The study included 11 922 children hospitalized in the period from 1.01 to 31.12.2007. In this group, 731 infants have birth weight < 1500 grams (from 2.2% to 64.2% in individual units, median--7.3%). The mean consumption of antibacterial drugs was 48.52 DDD/1 000 person-days (P-D) of stay among the entire study population (median--42,52), and varied from 23.13 to 85.82 DDD/1,000 P-D. However, this difference has not been statistically significant. The most commonly used group of antibiotics were beta-lactams--in four out of five units the percentage of its usage ranged from 48.71% to 74.67%. Next group were aminoglicosides--in one unit its usage reached 56.97% and in other ranged from 5.01% to 22.53%. Glycopeptides and macrolides were also used in every unit of the studied group. The usage of glycopeptides ranged from 1.7% to 10.81% and of macrolides from 1.32% to 15.71%. Different kinds of antibiotics were used occasionally. The differences of costs of purchase of one DDD between hospitals were greater and varied from 17,64 PLN/ DDD to 84,58 PLN/ DDD (average costs). A considerable range of costs index values was also noted for different groups of antibiotics. The costs of purchase of one DDD of beta-lactams varied from 19.54 PLN/ DDD to 68.35 PLN/ DDD; for aminoglicosides the cost varied from 4.61 PLN/ DDD to 122.9 PLN/ DDD, for glycopeptides--from 31.40 PLN/ DDD to 283.13 PLN/ DDD and in case of macrolides: from 12.05 PLN/ DDD to 90.77 PLN/ DDD. This differentiation of the cost of purchasing a single defined daily dose, taking into account the specific groups of antibiotics, did not have the characteristics of statistical significance., Conclusions: As expected, the antibiotic regimens in the studied wards were similar. This is due to a homogeneous population of hospitalized patients. However, the differences of costs of purchase of antibiotics observed in the study, indicate the considerable variety of the treatment patterns in Polish neonatology units and the need to develop and implement recommendations of effective pharmacotherapy for patients in intensive neonatal care units and the implementation of a unified model of infections surveillance.

Aim of Study: Analysis of prevalence and degree of intraventricular haemorrhages in preterm infants treated at the Institute of Mother and Child in Warsaw between 2005-2009.The results were compared with a similar analysis conducted between 1998-2002 in an effort to find an answer to the question regarding definite changes or trends of changes in this pathology over time., Material and Methods: The studied population comprised 350 infants born at 22-34 weeks of gestation, hospitalised between 2005-2009. These infants were compared with 354 infants treated between 1998 and 2002. Haemorrhages was diagnosed on the basis of repeated ultrasounds performed in a standard manner, through the fontanelle, according to classic rules. MR imaging was performed as required. The extent of haemorrhage was classified in stages 1 to 4. In deceased infants the stage of haemorrhage was verified on the basis of autopsy results., Results: The investigations carried out between 2005 and 2009 showed haemorrhages in 174 infants (49.7%). Extensive stage 3 haemorrhages were diagnosed in 45 infants (12.9%),and grade 4 in 35 infants (10,0%). 40 infants (11,4%) died during hospitalization. Autopsy was conducted in 26 deceased infants (65%); in 18 cases (69%) the diagnosis was confirmed and in no case was the diagnosis regarding the extent of haemorrhage changed. Studies carried out in the period 1998-2002 revealed haemmorhages in 248 infants (70%), including stage 3 in 67 infants (19%), and stage 4 in 34 infants (10%). 93 infants died during hospitalisation. Prevalence of all types of peri- intraventricular haemorrhages (PVH/IVH) is currently significantly lower, but the prevalence of extensive haemorrhages of grade 4 has not decreased. The number of deaths has decreased by half, although at present more infants with grade 4 haemorrhages survive. Comparison of prevalence of (PVH/IVH) of all grades in both cohorts of infants born up to 34 weeks of gestation in different periods, i.e. 1998-2002 and 2005-2009, shows a statistically significant decrease. However, the comparison of prevalence of extensive IVH of grade 4, does not show a statistically significant decrease. The percentage of women with threatened pregnancy who recieved corticotheraphy was 64.2%. This is still definitely too low., Conclusions: 1. Statistically significant decrease in the prevalence and the severity of peri-intraventricular haemorrhage in the analysis carried out between 2005 and 2009 is a positive conclusion. A negative finding is the fact that the incidence of IV degree intraventricular haemorrhage, does not show a falling trend. 2. A fall in the number of deaths in the population of premature infants born in our Department can be the result of significantly improved medical care in the compared groups. 3. In both cohorts still insufficient percentage of pregnant women receiving prenatal corticosteroids in cases of high risk pregnancy, could be linked with unsatisfactory prophylactie perinatal care. This could lead to lack of improvement in the incidence of IV degree intraventricular haemorrhage. 4. The existing data base in Poland on the incidence of PVH/IVH in the risk group, is insufficient for comparison with European Union Countries data in the EuroNeoNet. The significance of this pathology on individual, social and economic levels, creates a need to carry out periodical analysis, at regional level, concerning its incidence, causes and effects.

Adequate vitamin D intake and its status as well outdoor physical activity are important not only for normal bone development and Ca-P metabolism, but for optimal function of many organs and tissues throughout the body. Due to documented changes in dietary habits and physical activity level, both observed in growing children and adults, the prevalence of vitamin D insufficiency is continuously increasing. National Consultants and experts in this field established the Polish recommendations for prophylactic vitamin D supplementation in infants, toddlers, children and adolescents as well as in adults, including pregnant and lactating women based on current literature review. Taking into consideration pleyotropic vitamin D action and safety aspects serum 25-hydroxyvitamin D (25-OHD) level of 20-60 ng/ml (50-750 nmol/l) in children and 30-80 ng/ml (75-200 nmol/I) in adults is considered as optimal. Sunlight exposure inducing vitamin D production in the skin is main endogen source of vitamin D in the body but sunscreens may reduce skin synthesis by 90%. In Poland, skin synthesis is effective only from April to September so other sources of vitamin D such as diet and supplements play an important role. All newborns should be supplemented with 400 IU/d of vitamin D beginning from the first few days of life and continue during infancy. In formula fed infants vitamin D intake from the diet should be taken into account. In preterm infants higher total vitamin D intake (400-800 IU/day) is recommended till 40 weeks post conception. Total vitamin D intake in children and adolescents required from all sources (diet and/or supplements) should be 400 IU/d between October and March and throughout the whole year in case of inadequate vitamin D skin synthesis during the summer months. In overweight/obese children supplementation with higher dosage of vitamin D up to 800-1000 IU/d should be considered. Adults require 800-1000 IU/d of vitamin D. In pregnant and lactating women such supplementation is recommended in case of inadequate intake from diet and/or skin synthesis supplementation. Monitoring of serum 25-OHD level to define optimal dosage should be considered.

Appropriate state procurement system for vitamin D is important not only for the proper functioning of the skeletal, maintaining calcium and phosphorus homeostasis, but also for a number of other organs and tissues in our body. In connection with the change in lifestyle including dietary habits change, the widespread use of UV filters and less outdoor activity, observed an increase in the percentage of vitamin D deficiency, both in population and developmental age and adults. Based on the results of recent scientific research team of experts provides recommendations for preventive Polish supply of vitamin D in infants, children, adolescents and adults, including pregnant women and nursing mothers.

Adequate vitamin D intake and its status are important not only for bone health and Ca-P metabolism, but for optimal function of many organs and tissues throughout the body. Due to documented changes in dietary habits and physical activity level, both observed in growing children and adults, the prevalence of vitamin D insufficiency is continuously increasing. Basing on current literature review and opinions of National Consultants and experts in the field, polish recommendations for prophylactic vitamin D supplementation in infants, toddlers, children and adolescents as well as in adults, including pregnant and lactating women have been established.

Study was carried out from June to November 2008 in the group of newborn babies hospitalized at the highly specialized hospital. Twenty-six clinical isolates of ESBL-positive rods were collected from 24 patients. Infections incidence was confirmed on the level 3.4/1000 patientdays (pds), among infection dominated blood infection (41%) and pneumonia (31%). All isolates were analyzed for the presence of genes of the resistance (bla)SHV, (bla)TEM i (bla)CTX-M by the multiplex PCR amplification. Isolates were genotyped by PFGE. All isolates were characterized by the presence of the (bla)CTX-M gene. The most of ESBL-positive strains were polyclonal. Three endemic clones of the bacteria were distinguished (among Enterobacter and Klebsiella) which could be moved between patients. Appearing of infection among hospitalized newborn babies showed no relation with the frequency isolation of strains with ESBL phenotype during the period of the study at hospital. The dissemination of ESBLs is due to clonal spread or plasmid dissemination among or between species.

In this paper we outline the aims and methods of the Polish National Programme for Standardisation of Clinical Practice in Neonatology and Paediatric Intensive Care, with special reference to infants with low and extremely low birth weight. The aim of this Programme is to adjust the diagnostic and therapeutic procedures to the latest guide lines and recommendations. The first stage consisted of a national level survey in order to identify the diversity of procedures implemented in Medical University Clinical Departments, Neonatology Units and Paediatric Intensive Care Units. The survey also served to confront the legitimacy of the used procedures with the current clinical knowledge and research. It is planned to repeat the survey 24 months after the implementation of the latest recommendations with the aim to assess the impact of the Programme on clinical practice. Partial stages of the Programme were started since 2006. The survey is coordinated by an independent statistics unit. The recommendations are developed on published standards.

Recent literature concerning the epidemiology and the risk factors of cerebral palsy was reviewed. This search indicates that the prevalence of CP has stabilized in the last few years. Some studies have shown its tendency to decrease, especially in the group of preterm babies born later than 27 weeks of gestation. The important finding is that improvement of the survival rate in the VLBW infants does not increase CP morbidity. Other diagnostic procedures are discussed but head ultrascan remains the golden standard in CP diagnosis during the first 12 months of life, followed by MRI in the second year of life. The first part of this paper is a comparison between the epidemiological studies EPICURE and EPIPAGE from England and France and the Polish regional programme PREMATURITAS. In this study long-term development of preterm infants was evaluated. In all three studies the prevalence of CP was similar, but in the Polish programme the incidence of tetraplegia was highest. The principal factor behind this difference are more frequent changes in the head scan in the Polish study, in form of periventricular leucomalacia (PVL III degree) and IV grade intraventricular haemorrhage (IVH IV grade).

Unlabelled: The aim of the study was to analyse the data concerning infections in neonatal units and to assess the facilities for bacteriological diagnosis., Material: This national programme included 273 neonatal departments of which 175 were level I of referral, 72 departments were level II of referral, 26 units were level III of referral and 28 were paediatric intensive care departments., Method: was by use of anonymous questionnaires sent to the 273 neonatal departments. The questionnaire consisted of 15 questions concerning hospital infection, their diagnosis and treatment. Questions were standardized in a previous pilot study.The results are presented in 20 tables. They present bacteriological data routinely collected in the neonatal department, diagnostic criteria and antibiotic treatment., Conclusions: there is a need to introduce continous supervision concerning neonatal unit infections, which consists of coordinated and uniform procedures for material collection and pathogen identification.

Objective: The aim of this prospective study was to evaluate whether a change in the standard of newborn care for respiratory insufficiency by widely introducing more aggressive use of nasal continuous airway pressure (nCPAP) and including Infant Flow technology would result in satisfactory outcomes., Design: Prospectively defined analysis., Setting: Fifty-seven secondary and tertiary care neonatal centers in Poland., Patients: Patients were 1,299 newborns., Interventions: None., Measurements and Main Results: We carried out a prospectively defined analysis of 1,299 newborns included in the program between August 1, 2003, and April 30, 2005. The inclusion criterion was the occurrence of symptoms of respiratory failure irrespective of its etiology. Respiratory support was provided with the use of the Infant Flow Advance Driver. The analysis was made on data from prospectively designed questionnaires completed following each infant's treatment. Infants were placed into categories based on clinical indication for use. The primary end point was avoiding tracheal intubation. A high rate of acceptance of the new practice was observed across the substantial demographic and clinical diversity of newborns. Tracheal intubation was avoided in 78% of infants treated electively with nCPAP. Of those being weaned from mechanical ventilation, 61.2% were successfully weaned. Related complications were low (1.4% pneumothorax, 12% nasal injuries)., Conclusions: The new method of nCPAP with Infant Flow was adopted as standard practice in Poland. We monitored its safety and effectiveness over a 2-yr period and found it to be safe and effective as implemented. Additional research is still needed to determine the optimum patient population, strategy for use, and devices.

Conjoined twins are the rarest type of monozygotic, monochorionic, monoamniotic twins--incidence about 1:50000 - 1:100000. A conjoined twin pregnancy is a very special pathology in obstetrics and usually ends prematurely. 40% of twins are stillborn, while 35% die within 24 hours after delivery. The development of ultrasonography and in the last years also MRI, allows earlier detection and diagnosis of fetal malformation and enables precise evaluation of the anatomy, type of malformation and how the twins are conjoined. Chances of survival and way of delivery depends on the degree of fusion of the organs and possibilities of surgical separation. Obstetric care for a women with conjoined twins does not differ from that in a normal twin pregnancy, but the newborns require special medical care after delivery. We would like to stress the diagnostic problems and the difficult decisions that we encountered. The degree of conjoinment in this case excluded surgical separation of the twins. A multidisciplinary team of experts decided to end the pregnancy at 31 wks by cesarean section. Delivery at a later term could increase the risk of uterine rupture and surgical complications.

Aim: Complex evaluation of the development of infants until the end of the second year of life, including neurological and sensory development. A prospective cohort study., Population and Methods: 1) 264 premature babies born between 24 and 32 weeks of gestation during the period 1st of Oct 1998 and 30th of Sept 1999 in the region of Warsaw. 2) Age of examination at: 4th, 8th and 12th month of postconceptional age and 18th and 24th month of calendar age. 3) Neurological examination according to modified Denver's test, including the development of motor skills, coordination of vision and movement, speech and social contacts. Final division of development into: normal, uncertain and pathological. 4) Cerebral palsy was diagnosed according to the definition and classification proposed by the European Commission in 2002. 5) Retinopathy of prematurity (ROP): back of the eye (Fison's speculum) examination conducted from the 30th day of life, and follow-up depending of the escalation of changes. In cases of diagnosed ROP, stage 3 or 4 laser photocoagulation was performed. 6) Hearing examination: behavioral evaluation, in cases of uncertain or abnormal results ABR (auditory brain stem response) was carried out., Results: 162 children participated in the examination at the age of 2, which comprises 87% of the study population. While evaluating motor and sensory development of study population at 2 years of age, normal development was seen among 88% of children, cerebral palsy of different types (with majority of serious cases) was diagnosed in 8% of children and 2 children were blind. Uncertain development was stated for 4% of children, and 1 of them was deaf. 20% of children experienced delay in speech development and hyperactivity. Among babies born before 28th week of gestational age, 2-3 times higher percentage of 3rd stage of retinopathy of prematurity (ROP) was stated in comparison with developed countries. Nevertheless, no case of blindness was observed in this group of children, which may prove effective screening and effective therapy. At the same time 65% of children with 3rd stage ROP have some problems with vision (squint, short sightedness). The incidence of bronchopulmonary dysplasia-BPD (16%) and chronic lung disease (CLD) (11%) were relatively low. However, the percentage of hospitalization among children with CLD under the age of 2, which was caused by respiratory problems, was 37% compared to 28% of children in which CLD was not diagnosed., Conclusions: 1) The incidence of cerebral palsy in our study is not different from the results of other authors and was the highest among babies born before 29 weeks of gestation. 2) In the cerebral palsy group, higher incidence of tetraplegia was found, which may be connected with higher prevalence of hemorrhagic changes (IVH grade III or IV) and hypoxic -- ischaemic changes (PVL). 3) A relationship was found between cranial ultrasound (US) at 40 weeks of postconceptional age after PLV and the child's motor development at 2 years of age: normalization in the US was connected with correct development. 4) Incidence of ROP grade 3 was stated to be three times higher compared to other authors. No case of blindness was stated, which proves effectiveness of screening and treatment procedures. 5) Only one case of deafness due to congenital malformation was found. 6) The incidence of bronchopulmonary dysplasia (BPD) and chronic lung disease (CLD) was comparable to data from developed countries. However, the percentage of hospitalization for all respiratory problems among children with CLD under the age of 2 was twice as high as in the remaining population. 7) Developmental disorders such as: hyperactivity, delay of speech and vision problems (strabismus and short sightedness) indicate the need for continued evaluation of this group of children up to school age (5-7).

Unlabelled: AIM OF THIS PAPER: To present the opinions of doctors and nurses on the limitations of resuscitation and treatment of extremely premature newborns., Material and Methods: Anonymous questionnaire studies were carried out in 342 doctors and 1194 nurses from 6 provinces of Poland. The authors compared the answers of doctors and nurses as well as the answers form different provinces. The results were processed using the Chi2 test, with the significance level p<0.05., Results: The will to resuscitate the neonate, regardless of its birth weight was declared by 29% of the physicians and 49% of the nurses, regardless of the gestational age - by 21% of the physicians and 47% of the nurses. Resuscitation of an extremely immature, asphyctic newborn was declared by 71% of the physicians and 59% of the nurses. Limitation of therapy after diagnosing severe intracranial hemorrhage is declared by 67% of the physicians and 45% of the nurses. 37% of the doctors and 30% of the nurses would comply with parents' will when deciding about resuscitation. 44% of the physicians and 31% of the nurses declare taking parents' decision into account in the matter of abandoning resuscitation., Conclusions: 1. There is a higher percentage of persons convinced about the necessity of resuscitation of every newborn, regardless of its maturity, among the nurses than among the doctors. 2. Among the nurses there are more persons, who are sceptical about saving the extremely premature newborns born with asphyxia, whereas among the doctors there are more persons inclined to stop therapy in case of a severe intracranial hemorrhage. 3. The most controversial are problems concerning the consideration of parents' will in decision about whether to continue or abandon resuscitation, but physicians are more apt to regard parents' will in resuscitation in some situations. 4. The analysis of the questionnaire points to the need for deeper knowledge of the present mortality rates of the extremely immature newborns and further development of the surviving ones among the physicians and nurses.

Aim: To assess the efficacy and safety of early treatment with ibuprofen (IBU) and indomethacin (INDO) of patent ductus arteriosus in preterm infants. Prospective study with blind trial., Material and Methods: We studied 35 preterm infants (19 treated with INDO, 16 IBU) (gestation age <33 and birth weight < 1500 g), who had an echocardiographicaly confirmed patent ductus arteriosus (PDA). The infants were randomly assigned in two groups to receive INDO (0.2-0.2-0.2 mg/kg) or IBU (10-5-5 mg/kg) in first 72 hours of life (average 2 days of life). The rate of ductal closure, the need for surgical ligation, side effects, complications, and the infants clinical course were recorded., Results: The rate of ductal closure was similar in two groups (15/19, 80% INDO; 11/16, 69% IBU). 27 infants (15 INDO, 12 IBU) were treated per protocol (3 doses). For remaining 8 infants we stopped treatment due to side effects. In the IBU group the main reason to stop treatment was pulmonary hemorrhage (3/16, 19%) and pulmonary hypertension (1/16, 6%), but in the INDO group it was increased serum creatinine and urea nitrogen concentrations (3/19, 16%) and intraventricular hemorrhage (IVH IV) grade (1/19 5%). In IBU group vs. INDO, urine output decreased (p=0.02), but never before below the level of oliguria (defined as urine output below 1 ml/kg/h). Risk of necrotizing enterocolitis (NEC) grade II was similar in two groups, but only patients treated with INDO showed intestinal perforations (p=ns). They received also postnatal hydrocortisone and we showed near significant tendency (p=0.06) for intestinal perforation in patients treated with INDO and hydrocortisone. There were no significant differences with respect to IVH or PVL between the groups., Conclusions: The efficacy of ibuprofen and indomethacin in PDA treatment is similar. Treatment of ibuprofen and indomethacin may cause transient renal dysfunction: diminished urine output and increase of serum creatinine and urea nitrogen concentrations. Indomethacin, especially with concomitant treatment with hydrocortisone, may increase the risk of intestinal perforation.

Severe developmental impairment in children born as extremly prematures include cerebral palsy, subnormal cognitive function, deafness and blindness. The rate of severe disabilities range from 5 to 30%. This article reviews what is known about early brain injury and its developmental sequel.

Unlabelled: The aim of the study was to evaluate the influence of the neonatal diet on bone mineralization. We studied 21 neonates (M-10, F-11) in gestational age 27-35 weeks with body birth weight ranging from 860 to 1800 g (mean 1343 g). 12 children received breast milk with fortifier (BMF--group 1) and 9 children were fed with hydrolysate formulas (group 2). The feeding was modified after child body weight reached 3500 g. The bone mineral density measured by densitometry (DPX) technique and body weight gain were evaluated., Results: Mean TBBMD (total body bone mass density--g/cm2) at week 40 of postconceptual age in group 1 was 0.450 +/- 0.021 and in group 2 0.457 +/- 0.049. At 3rd month TBBMD was respectively 0.496 +/- 0.034 and 0.478 +/- 0.016, and at 6 month of corrected age 0.546 +/- 0.055 and 0.564 +/- 0.021. The differences were not statistically significant. There were no differences in body weight gain between both groups. At month 7-9 of corrected age body weight were 8650 g and 8475 g respectively., Conclusion: We did not demonstrate the differences in TBBMD and body weight gain between children fed with breast milk and BMF or hydrolysate formulas in the first months of life. The low number of children does not allow to generalize this conclusion.
