Pneumocystis jirovecii Colonization in Preterm Newborns With Respiratory Distress Syndrome.

We describe the prevalence of Pneumocystis jirovecii in mother-infant pairs of very low birth weight newborns <32 weeks gestation. Molecular and microscopic methods were used for detection of P. jirovecii in patients' specimens. Pneumocystis DNA was detected in 8 nasopharyngeal aspirates (14%) of 56 newborns and in 7 oral washes (21%) of 34 mothers. Pneumocystis detection immediately after birth suggests the possibility of its transplacental transmission. Compared to noncolonized infants, more frequent occurrence of bronchopulmonary dysplasia was seen in colonized infants (P = .02), suggesting a potential clinical importance of this pathogen in abnormal lung development.

INTRODUCTION: Wady letalne prowadza do wewnatrzmacicznego zgonu plodu lub dziecka bezposrednio po urodzeniu lub we wczesnym okresie niemowlecym, bez wzgledu na zastosowane leczenie. W przypadku wad letalnych nie ma mozliwosci skutecznej pomocy dziecku, mimo postepu mi zeadsytcoysnoyw ania najnowoczesniejszej aparatury lub terapii. Rodzice, którzy decyduja sie na urodzenie dziecka z wada letalna moga byc objeci perinatalna opieka hospicyjna, która ma charakter kompleksowy. Polega ona na wsparciu ciezarnej w okresie przygotowania do porodu, w czasie porodu i po porodzie oraz na wsparciu jej rodziny oraz obejmuje udzielenie rodzicom pelnej informacji o chorobie ich dziecka. Opieka nad dzieckiem po urodzeniu jest nastawiona na ochrone przed uporczywa terapia i zapewnienie dziecku opieki paliatywnej. CEL: Wykazanie znaczenia perinatalnej opieki paliatywnej dla kobiet w ciazy, u których wyniki badan prenatalnych wskazywaly na ciezkie zaburzenie rozwojowe u plodu o potencjalnie letalnym rokowaniu oraz przedstawienie schematu postepowania wedlug modelu wewnatrzszpitalnego hospicjum perinatalnego. MATERIAL I METODY: Analiza retrospektywna objeto dokumentacje 67 pacjentek skierowanych do Programu RAZEM we Wroclawiu w latach 2014-2018 z powodu nieprawidlowych wyników badan prenatalnych (ultrasonograficznych lub/i genetycznych), które wskazywaly na ciezkie zaburzenie rozwojowe u plodu o potencjalnie letalnym rokowaniu. Dokonanoanalizy danych socjodemograficznych, danych klinicznych rozpoznania choroby u plodu, przebiegu ciazy i porodu, trybu postepowania w okresie prenatalnym, podczas porodu i po urodzeniu sie dziecka. WYNIKI: Do Programu zostalo skierowanych 67 kobiet w wieku 20-43 lat (srednio 31,2), które zglaszaly sie w okresie od 15 do 39 tygodnia ciazy (srednio w 25. tygodniu ciazy). Do opieki paliatywnej zakwalifikowano 57 kobiet, czyli 85% skierowanych do programu. Opieke paliatywna kontynuowano u 51 pacjentek, poniewaz 6 kobiet w trakcie procesu diagnostycznego zdecydowalo sie na zakonczenie ciazy (10,5%). Najczestszymi zaburzeniami u plodów byly aberracje chromosomowe, wady OUN i wady nerek. W 95% przypadków doszlo do obumarcia wewnatrzmacicznego plodu lub smierci noworodka. WNIOSKI: Perinatalna opieka paliatywna jest niezbedna forma opieki dla kobiet w ciazy, u których wyniki badan prenatalnych wskazuja na ciezkie zaburzenie rozwojowe u plodu o potencjalnie letalnym rokowaniu.

INTRODUCTION: Lethal defects lead to the intrauterine death of the fetus or the passing away of the child immediately after birth or in early infancy, regardless of the treatment used. In the case of lethal defects, it is not possible to effectively help the child, despite using the most modern equipment or medicines in the treatment or the progress made by medicine. Parents, who decide to continue the pregnancy, although the fetus has a lethal defect that cannot be cured, may be covered by perinatal hospice care, which is comprehensive and consists in supporting the pregnant woman during the prenatal time, during delivery and after delivery and support of her family, giving full information to the parents about their child's illness. Childcare after birth is focused on protecting the infant from persistent therapy and providing him with appropriate conditions. AIM: To demonstrate the role of perinatal palliative care for pregnant women in whom the results of prenatal tests pointed to a severe developmental disorder in the fetus with a potentially lethal prognosis, and to present a pattern of behavior for their hospitalization in the perinatal hospice. MATERIALS AND METHODS: The retrospective analysis included documentation of 67 patients referred to the RAZEM (TOGETHER) Program in Wroclaw in 2014-2018 due to abnormal results of (ultrasound and / or genetic) prenatal tests, which indicated a serious developmental disorder in the fetus with potentially lethal prognosis. Analysis was conducted of sociodemographic data, clinical data on fetal diagnosis, pregnancy and delivery, the procedure for prenatal delivery and postnatal birth. RESULTS: 67 women aged 20-43 years (mean 31.2) were referred to the RAZEM Program. Out of these, 57 women were enrolled for palliative care, which accounted for 85% of those referred to the program. Palliative care was continued in 51 patients, because 6 women decided to terminate their pregnancy during the diagnostic process (10.5%). The most common abnormalities in the fetuses were chromosomal aberrations, CNS defects and kidney defects. In 95% of the cases, intrauterine fetal death or neonatal death occurred. CONCLUSIONS: Perinatal palliative care is an indispensable form of care for pregnant women in whom the results of prenatal tests indicate a serious developmental disorder in the fetus with potentially lethal prognosis. The in-hospital model of a perinatal hospice is a beneficial form of care, as it ensures consistency and good communication in the team, which favourably affects its quality.

Individualization of treatment with gentamicin in neonates based on drug concentration in the blood serum.

OBJECTIVE: Aim: To evaluate how useful it is to make measurements of gentamicin concentrations in newborns' blood in order to optimize antibiotic therapy. PATIENTS AND METHODS: Material and methods: 73 newborns empirically treated with gentamicin, in doses consistent with the Neofax® guidelines. There were 152 measurements of maximum and minimum serum gentamicin concentrations. Samples were determined based on the chemiluminescence technique on the Siemens Advia Centaur analyzer. The concentrations of gentamicin that were measured were compared with various therapeutic ranges used in the literature. RESULTS: Results: According to the standards adopted in the University Hospital in Wroclaw, the maximum concentration was reached in 38.16% of all the children, while the minimum in 26.32%. In other children the concentrations were below or above the therapeutic range. According to the Neofax® guidelines, the intended maximum concentration was observed in 71.05% of the newborns, and the minimum in 32.89%. The minimum concentration of <2 mg/L was found in 93.42% of the newborns, while >2 mg/L was determined in 33.33%, despite a 48-hour dosing interval. These were premature babies (<28th week of gestational age) and 55.56% of them reached a maximum concentration of 5-12 mg/L. There was no significant correlation between maximum or minimum concentration and gestational age or body weight. CONCLUSION: Conclusions: 1. The dosage of gentamicin in newborns according to the Neofax® recommendations does not ensure achieving the intended serum antibiotic concentrations. 2. In order to optimize gentamicin therapy in newborns it is necessary to individualize the dose based on measurements of drug concentrations in the blood and pharmacokinetic calculations.

[Vegetarian diet in pregnancy and lactation - safety and rules of balancing meal plan in the aspect of optimal fetal and infant development]. / Dieta wegetarianska w ciazy i okresie laktacji ­ bezpieczenstwo i zasady bilansowania jadlospisu w aspekcie optymalnego rozwoju plodu i noworodka.

Pregnancy is a period of intense fetal development, as well as maternal physiological adaptation. During this period a varied diet is particularly important, as intake of macronutrients and micronutrients directly affects pregnancy outcome and the quality of breast milk. The dietary recommendations for pregnant women are indeed very similar to those for other adults, but with a few remarkable exceptions. Therefore, it is important to evaluate, monitor, and, when appropriate, make changes to improve maternal nutrition both before and during pregnancy and lactation, while respecting patients' choices. Growing interest of vegetarian diets needs to be included, as pregnant women may present with unique nutrient deficiencies. However, evidencebased reviews showed that "vegetarian diets can be nutritionally adequate in pregnancy and result in positive maternal and infant health outcomes". This statements is supported by worldwide nutrition specialists, though, the risk and consequences of nutrient deficiencies is emphasized. The nutritional adequacy of a vegetarian diet must be judged individually, not on the basis of what it is called, but on the type, amount, variety and bioavaliability of nutrients that are consumed. Special consideration is required for proteins, calcium, iron, zinc, vitamin B12 and omega-3 fatty acids. Moreover, following advices regarding micronutrients supplementation is essential. This article provides guidelines for counseling vegetarian patients in prenatal and postnatal care.

Congenital skin aplasia on the lower limb in a premature infant with ELBW--case report.

Aplasia cutis congenita (ACC) is usually located on the hairy scalp, on the vertex of the head, but can also occur in other locations, such as limbs, trunk. Congenital skin aplasia on the lower limb is very rare disorder. The exact etiopathogenesis is not known, but intrauterine conditions play a role in its development. ACC visually resembles an ulceration, with a smooth pink surface, which in most cases heals spontaneously. Depending on the wound size and whether signs of inflammation are present, the lesion may require local treatment. In the described case, surgical treatment was carried out because of the extreme prematurity of the infant. The outcome was satisfactory, causing no adverse impact on the child's development during the infancy.

Neonatal outcome from triplet interval delayed delivery: a case report.

In the past decades, we have observed a large increase in the number of multifetal pregnancies, which is mainly associated with the introduction of assisted reproductive techniques. Even though neonatal intensive care of very premature infants has improved significantly, the risk of mortality and long-term morbidity is still much higher among these newborns. A longer interdelivery period may reduce perinatal mortality and morbidity. The authors report the case of a delayed interval delivery in trichorionic, triamniotic triplet pregnancy. After the labor of the first fetus in the 22nd week of gestation, a 75-day interval was achieved before the delayed delivery. To save the surviving fetuses, the umbilical cord was ligated at the cervical level immediately after the first delivery. The patient received antibiotics, tocolytics, and corticosteroids. A baby boy who weighed 1750 g and a girl who weighed 1700 g were successfully delivered by cesarean section in the 33rd week of pregnancy. The babies were discharged home at the age of 28 days. A follow-up examination 20 weeks later showed that their neurological development was normal and without any major problems. The maternal postpartum course was uneventful; the patient stayed in hospital taking care of the babies.

Influence of sleep position experience on ability of prone-sleeping infants to escape from asphyxiating microenvironments by changing head position.

OBJECTIVE: Several studies have found that back- or side-sleeping infants who are inexperienced in prone sleeping are at much higher risk for sudden infant death syndrome (SIDS) when they turn to prone or are placed prone for sleep compared with infants who normally sleep prone. Moreover, such inexperienced infants are more likely to be found in the face-down position at death after being placed prone compared with SIDS infants who are experienced in prone sleeping. We hypothesized that lack of experience in prone sleeping is associated with increased difficulty in changing head position to avoid an asphyxiating sleep environment. METHODS: We studied 38 healthy infants while they slept prone. Half of these were experienced and half were inexperienced in prone sleeping. To create a mildly asphyxiating microenvironment, we placed infants to sleep prone with their faces covered by soft bedding. We recorded inspired CO2 (CO2I), electrocardiogram, and respiration, and we videotaped head movements. Also, we assessed gross motor development (Denver Development Scale). RESULTS: When sleeping prone, with their faces covered by bedding, all infants experienced mild asphyxia as a result of rebreathing. All aroused and attempted escape from this environment. Infants used 3 stereotyped head-repositioning strategies. The least effective was nuzzling into the bedding with occasional brief head lifts. More effective were head lifts combined with a head turn. Some infants, however, could turn only to 1 side, right or left. Infants who were inexperienced in prone sleeping had less effective protective behaviors than experienced infants. Infant age did not correlate with efficacy of protective behaviors. Infants who were experienced in prone sleep had advanced gross motor development compared with inexperienced infants. CONCLUSION: Infants who are inexperienced in prone sleeping have decreased ability to escape from asphyxiating sleep environments when placed prone. These observations potentially explain the increased risk associated with prone sleep in infants who are inexperienced. The increased occurrence of the face-down position in such infants is also potentially explained. These findings suggest that airway protective behaviors may be acquired through the mechanism of operant conditioning (learning).

Occurrence and mechanisms of sudden oxygen desaturation in infants who sleep face down.

OBJECTIVE: Infants who sleep prone and face down on soft bedding are particularly vulnerable for sudden infant death syndrome. It has been suggested that 1 mechanism of death in this situation involves rebreathing of expired air. Many infants tolerate rebreathing while lying prone face down for long periods with stable saturations. Others occasionally have rapid desaturations and may require intervention to terminate rebreathing. The present study had 3 objectives: 1) to determine the frequency of rapid desaturations in a large group of healthy infants, 2) to elucidate the mechanism of these desaturations, and 3) to determine the timing of these events during periods of rebreathing. METHODS: We studied respiratory tracings and videotapes of 56 healthy 1- to 6-month-old infants who were sleeping face down and rebreathing on soft bedding in our laboratory. We compared the frequency of desaturations during rebreathing and nonrebreathing periods. We measured respiratory frequency and apnea occurrence before desaturation and nonrebreathing control episodes. We also measured minute ventilation during steady state before desaturation and just before desaturation. RESULTS: There were 25 desaturation episodes in infants while rebreathing, occurring in 11 (19.6%) of the 56 infants. Episodes were significantly more frequent during rebreathing than during nonrebreathing periods. Three desaturation episodes reached <85%; 2 required intervention to terminate rebreathing. The respiratory frequency was not different between nonrebreathing control and desaturation episodes. Brief apneas were significantly more frequent preceding desaturation than control episodes (44% vs 4%). Just before episodes, there was a transient decrease in minute volume despite increasing inspired carbon dioxide in 3 episodes. There was evidence of partial or complete pharyngeal airway obstruction in 3 episodes. Thirty-six percent of all episodes were immediately preceded by behavioral arousal. CONCLUSIONS: Rebreathing in prone sleeping infants is associated with an increased frequency of episodic desaturations. Desaturation may result from respiratory pattern changes such as brief apneas often associated with evidence of behavioral arousal or failure to increase ventilation in the face of rising inspired carbon dioxide, also associated with behavioral arousal.
