Introducción: La listeriosis es una patología de baja incidencia, con síntomas leves y autolimitados en la población en general, sin embargo, la transmisión materno-fetal, puede generar cuadros graves en neonatos, manifestados como sepsis, meningitis, endocarditis, encefalitis, meningoencefalitis. El diagnóstico oportuno por clínica y datos de laboratorio en coyuntura con la terapéutica adecuada favorecen la resolución de la enfermedad. Caso clínico: Neonato prematuro tardío de 34 semanas, 6 días de edad gestacional, nació por cesárea iterativa, al nacimiento no vigoroso con líquido amniótico meconial pesado, requirió reanimación básica y avanzada. Evolución: Por los antecedentes natales se realizó estudio de infección, con reporte positivo y desarrollo en hemocultivos de Listeria Monocytogenes, diagnóstico de sepsis, meningitis y conjuntivitis, recibió antibiótico terapia intrave-nosa, completó tratamiento y presentó evolución clínica favorable. Conclusiones: En el presente caso la listeriosis de transmisión materno-neonatal tuvo una presentación grave con aspiración de líquido meconial que requirió intubación y soporte ventilatorio, el paciente desarrolló meningitis y conjuntivitis. En la placenta se presentó corionitis.
Introduction: Listeriosis is a low-incidence pathology with mild and self-limiting symptoms in the general population; however, maternal-fetal transmission can generate severe conditions in neonates, manifested as sepsis, meningitis, endocarditis, encephalitis, meningoencephalitis. Timely diagnosis by clinical and laboratory data in conjunction with adequate therapy favors the resolution of the disease. Clinical case: Late preterm neonate of 34 weeks, six days of gestational age, was born by repetitive cesarean section at non-vigorous birth with heavy meconium amniotic fluid and required basic and advanced resuscitation. Evolution: Based on the birth history, an infection study was carried out, with a favorable report and development of Listeria Monocytogenes in blood cultures, diagnosis of sepsis, meningitis, and conjunctivitis, received intravenous antibiotic therapy, completed treatment, and presented favorable clinical evolution. Conclusions: In the present case, the listeriosis of maternal-neonatal transmission had a severe presentation with the aspiration of meconium fluid that required intubation and ventilatory support; the patient developed meningitis and conjunctivitis. Chorionitis occurs in the placenta.

Neonates born through meconium-stained amniotic fluid (MSAF) may develop complications including meconium aspiration syndrome, persistent pulmonary hypertension of newborn and death. The approach to the resuscitation of these neonates has significantly evolved for the past few decades. Initially, under direct visualization technique, neonates with MSAF were commonly suctioned below the vocal cords soon after delivery. Since 2015, Neonatal Resuscitation Program (NRP®) of the American Academy of Pediatrics has recommended against "routine" endotracheal suctioning of non-vigorous neonates with MSAF but favored immediate resuscitation with positive pressure ventilation via face-mask bagging. However, the China neonatal resuscitation 2021 guidelines continue to recommend routine endotracheal suctioning of non-vigorous neonates born with MSAF at birth. This review article discusses the differences and the rationales in the approach in the resuscitation of neonates with MSAF between Chinese and American NRP® guidelines over the past 60 years.

OBJECTIVES@#To study the feasibility of tracheal intubation for meconium suction immediately after birth of nonvigorous neonates born through meconium-stained amniotic fluid (MSAF).@*METHODS@#A retrospective cohort study was performed on nonvigorous neonates born through MSAF who were admitted to the Department of Neonatology, Zhecheng People's Hospital. The neonates without meconium suction who were admitted from July 1, 2017 to June 30, 2018 were enrolled as the control group. The neonates who underwent meconium suction from July 1, 2018 to June 30, 2019 were enrolled as the suction group. The two groups were compared in terms of the mortality rate and the incidence rates of neonatal meconium aspiration syndrome (MAS), persistent pulmonary hypertension of the newborn, pneumothorax, and pulmonary hemorrhage.@*RESULTS@#There were 80 neonates in the control group and 71 in the suction group. There were no significant differences between the two groups in the incidence rates of MAS (11% vs 7%), persistent pulmonary hypertension of the newborn (5% vs 4%), pneumothorax (3% vs 1%), and death (0% vs 1%). Compared with the control group, the suction group had a significantly lower proportion of neonates requiring oxygen inhalation (16% vs 33%, P<0.05), noninvasive respiratory support (25% vs 41%, P<0.05) or mechanical ventilation (10% vs 23%, P<0.05) and significantly shorter duration of noninvasive ventilation [(58±24) hours vs (83±41) hours, P<0.05] and length of hospital stay [6(4, 8) days vs 7(5, 10) days, P<0.05].@*CONCLUSIONS@#Although tracheal intubation for meconium suction immediately after birth may shorten the duration of respiratory support for mild respiratory problems, it cannot reduce the incidence rate of MAS, mortality rate, or the incidence rate of serious complications in nonvigorous infants born through MSAF.

OBJECTIVES@#To study the clinical features of severe meconium aspiration syndrome (MAS) and early predicting factors for the development of severe MAS in neonates with meconium-stained amniotic fluid (MSAF).@*METHODS@#A total of 295 neonates who were hospitalized due to Ⅲ° MSAF from January 2018 to December 2019 were enrolled as subjects. The neonates were classified to a non-MAS group (n=199), a mild/moderate MAS group (n=77), and a severe MAS group (n=19). A retrospective analysis was performed for general clinical data, blood gas parameters, infection indicators, and perinatal clinical data of the mother. The respiratory support regimens after birth were compared among the three groups. The receiver operating characteristic (ROC) curve and multivariate logistic regression analysis were used to investigate predicting factors for the development of severe MAS in neonates with MSAF.@*RESULTS@#Among the 295 neonates with MSAF, 32.5% (96/295) experienced MAS, among whom 20% (19/96) had severe MAS. Compared with the mild/moderate MAS group and the non-MAS group, the severe MAS group had a significantly lower 5-minute Apgar score (P<0.05) and a significantly higher blood lactate level in the umbilical artery (P<0.05). Compared with the non-MAS group, the severe MAS group had a significantly higher level of interleukin-6 (IL-6) in peripheral blood at 1 hour after birth (P<0.017). In the severe MAS group, 79% (15/19) of the neonates were born inactive, among whom 13 underwent meconium suctioning, and 100% of the neonates started to receive mechanical ventilation within 24 hours. Peripheral blood IL-6 >39.02 pg/mL and white blood cell count (WBC) >30.345×109/L at 1 hour after birth were early predicting indicators for severe MAS in neonates with MSAF (P<0.05).@*CONCLUSIONS@#Meconium suctioning cannot completely prevent the onset of severe MAS in neonates with MSAF. The neonates with severe MAS may develop severe respiratory distress and require mechanical ventilation early after birth. Close monitoring of blood lactate in the umbilical artery and peripheral blood IL-6 and WBC at 1 hour after birth may help with early prediction of the development and severity of MAS.

RESUMEN El objetivo del estudio fue determinar la influencia del nacimiento por vía vaginal en comparación con el nacimiento por cesárea sobre el contenido de bacterias acidolácticas con características probióticas de los recién nacidos. Se evaluaron muestras de meconio de recién nacidos por vía vaginal y por cesárea que fueron debidamente enriquecidas, sembradas e incubadas. Las colonias resultantes fueron identificadas para ser sometidas a tolerancia de sales biliares, pH ácido y fermentación. Se obtuvo un mayor desa rrollo de colonias en meconio de nacidos por vía vaginal en comparación con los nacidos por cesárea (p<0,001). Se aislaron 48 cepas en total, siendo en su gran mayoría tolerantes a sales biliares y pH ácido; asimismo, la fermentación de lactosa en leche fue positiva. Este estudio respalda hallazgos previos que sustentan que el nacimiento por vía vaginal favorece al mayor, desarrollo de bacterias acidolácticas con características probióticas, en comparación con el nacimiento por cesárea, y destaca la presencia de bac terias del género Lactobacillus.
ABSTRACT The study's objective was to determine the influence of vaginal birth compared to cesarean birth on the content of lactic acid bacteria with probiotic characteristics from newborns. Vaginal and cesarean sec tion meconium samples of lactic acid were evaluated, which were duly enriched, seeded and incubated. The resulting colonies were identified to be subjected to bile salt tolerance, acid pH, and fermentation. A greater development of meconium colonies was obtained in those born vaginally compared to those born by caesarean section (p <0.001). A total of 48 strains were isolated, the majority being tolerant to bile salts and acid pH; likewise, the fermentation of lactose in milk was positive. This study supports previous findings that support vaginal birth favors the greatest development of lactic acid bacteria with probiotic characteristics, compared to cesarean birth, and highlights the presence of bacteria of the genus Lactobacillus.

INTRODUCCIÓN La peritonitis meconial (PM) es una peritonitis localizada o generalizada, aséptica, química o de cuerpo extraño; producto del paso de meconio a la cavidad peritoneal y esta correlacionada con la perforación prenatal del tracto digestivo. Se presenta en 1 de cada 30.000 recién nacidos (RN). El diagnostico ecográfico prenatal mejora los resultados perinatales, el hallazgo más frecuente es la ascitis. La PM requiere un tratamiento multidisciplinario urgente, la mayoría es de resolución quirúrgica. OBJETIVO Dar a conocer una patología infrecuente, que requiere un alto grado de sospecha diagnostica para otorgar un manejo perinatal específico y oportuno. Caso clínico Primigesta de 29 años sin antecedentes mórbidos, cursando embarazo controlado de 36+5 semanas. En control ecográfico se evidencia ascitis fetal. Se hospitaliza en alto riesgo obstétrico, descartando patología metabólica e infecciosa. A las 37 semanas por cesárea de urgencia, se obtiene RN con distensión abdominal y hepatomegalia. En laparotomía exploradora se evidencia asas intestinales indemnes. En re intervención se encuentra hernia de íleon distal perforada, se confecciona ostomia, evoluciona favorablemente y es dado de alta. DISCUSIÓN Es fundamental considerar la PM dentro de los diagnósticos diferenciales de ascitis fetal. Un diagnóstico oportuno mejora los resultados perinatales y permite prevenir posibles complicaciones.
INTRODUCTION Meconial peritonitis (PM) is localized or generalized peritonitis, aseptic, chemical or strange body; a product of meconium steps to the peritoneal cavity and is correlated with prenatal perforation of the digestive tract. It occurs in 1 in 30,000 newborns. Prenatal ultrasound diagnosis improves perinatal outcomes, the most frequent finding is ascites. PM requires urgent multidisciplinary treatment, most of cases need surgical resolution. OBJECTIVE To present an infrequent pathology, which requires a high degree of diagnostic suspicion to grant a specific and timely perinatal management. Clinical case Pregnant 29 years old woman without morbid history, 36 weeks of controlled pregnancy. Ultrasound control shown fetal ascites. He is hospitalized at high obstetric risk, ruling out metabolic and infectious pathology. At 37 weeks by emergency caesarean section, is obtained a baby boy with abdominal distension and hepatomegaly. In exploratory laparotomy there are undamaged intestinal handles. In re intervention it is noted herniated perforated distal ileum, ostomy is made. Patient evolves favourably and is discharged. DISCUSSION It is essential consider PM within the differential diagnoses of fetal ascites. An opportune diagnosis improves the perinatal results and could avoids possible complications.

PURPOSE: Meconium aspiration is assumed to be a risk factor for bacterial infection, and patients with meconium aspiration syndrome (MAS) are commonly treated with empiric antibiotics in clinical settings. However, little is known about the effectiveness of the empirical antibiotics treatment. Here, we compared the short-term clinical outcomes associated with empirical antibiotics treatment in non-ventilated cases of MAS. METHODS: A retrospective study was conducted on infants admitted with non-ventilated cases of MAS from March 2008 to September 2016. The infants enrolled in the study were divided into two groups based on the antibiotics treatment, and their clinical outcomes were compared. The incidence of sepsis during the hospitalization period and the incidence of delayed sepsis up to 3 months were evaluated. The effects of empirical antibiotic use on respiratory symptoms were evaluated, and the complications were compared. RESULTS: A total of 109 infants were evaluated, of which 61 (56.0%) received antibiotics and 48 (44.0%) did not receive antibiotics. No differences in clinical characteristics were noted between the two groups. However, the empirical antibiotics group showed a significantly higher mean of respiratory rates, C-reactive protein levels, and positive rates, as well as a significantly longer hospitalization period. In clinical outcomes, there were no differences in sepsis rates or respiratory support duration. Furthermore, there were no differences in complications. CONCLUSION: The empirical use of antibiotics did not affect the clinical outcomes in cases of non-ventilated MAS. The role of empirical antibiotics in these infants may need to be reevaluated.

PURPOSE: This study aimed to evaluate the clinical and radiologic findings suggestive of spontaneous intestinal perforation (SIP) in extremely-low-birth-weight infants (ELBWIs) with persistent gasless abdomen, and to investigate the usefulness of abdominal ultrasonography for the diagnosis of SIP. METHODS: In total, 22 infants with birth weights less than 1,000 g who showed persistent gasless abdomen on simple abdominal radiography were included. Perinatal, neonatal, and perioperative clinical findings were retrospectively reviewed, and the risk factors for intestinal perforation were evaluated. Abdominal sonographic findings suggestive of intestinal perforation were also identified, and postoperative short-term outcomes were evaluated. RESULTS: In total, eight of the 22 infants (36.4%) with gasless abdomen had SIP. The number of infants with patent ductus arteriosus who were treated with intravenous ibuprofen or indomethacin was significantly higher in the SIP group than in the non-SIP group (P<0.05). Greenish or red gastric residue, abdominal distension, or decreased bowel sound were more frequent in infants with SIP (P<0.05), in addition to gray or bluish discoloration of abdomen, suggestive of meconium peritonitis (P<0.05). Pneumoperitoneum on simple abdominal radiography was found in only one of the eight infants (12.5%) with SIP. Intramural echogenicity and echogenic extramural material on abdominal ultrasonography were exclusively observed in infants with SIP. Four infants (50%) with SIP died after surgical intervention. CONCLUSION: Intestinal perforation may occur in ELBWIs with gasless abdomen. As intramural echogenicity and extraluminal echogenic materials on abdominal ultrasonography are indicative of SIP, this technique could be useful for diagnosing SIP.

Waardenburg syndrome (WS) type IV is characterized by pigmentary abnormalities, deafness and Hirschsprung's disease. This syndrome can be triggered by dysregulation of the SOX10 gene, which belongs to the SOX (SRY-related high-mobility group-box) family of genes. We discuss the first known case of a SOX10 frameshift mutation variant defined as c.895delC causing WS type IV without Hirschsprung's disease. This female patient of unrelated Kuwaiti parents, who tested negative for cystic fibrosis and Hirschsprung's disease, was born with meconium ileus and malrotation and had multiple surgical complications likely due to chronic intestinal pseudo-obstruction. These complications included small intestinal necrosis requiring resection, development of a spontaneous fistula between the duodenum and jejunum after being left in discontinuity, and short gut syndrome. This case and previously reported cases demonstrate that SOX10 gene sequencing is a consideration in WS patients without aganglionosis but with intestinal dysfunction.

Meconium peritonitis as a cause of non-immune hydrops in neonates is rarely reported. Here we report such a rare occurrence. In our case, a routine antenatal scan at 25 weeks revealed isolated ascites. By 31 weeks of gestation, all features of hydrops were observed in scans. However, antenatal workup for immune and non-immune hydrops was negative. Subsequently, a preterm hydropic female baby was delivered at 32 weeks. She required intubation and ventilator support. An X-ray revealed calcification in the abdomen suggestive of meconium peritonitis. Ultrasound showed gross ascites, a giant cyst compressing the inferior vena cava, and minimal bilateral pleural effusion. Emergency laparotomy revealed meconium pellets and perforation of the ileum. Double-barrel ileostomy was performed, and the edema resolved and activity improved. The baby was discharged after 3 weeks. Ileostomy closure was done at follow-up. The baby is growing well.

The omphalomesenteric duct is a link between the primitive midgut and the yolk sac. Normally, the duct obliterates around 6 weeks of gestation, yet varying degrees of incomplete obliteration can take place in 1%–4% of infants. This study described the case of a newborn with a patent omphalomesenteric duct remnant fistula identified at birth with meconium in the umbilical cord. At birth, the infant presented meconium staining and meconium discharged within the umbilical cord. Physical examination and other examinations showed no other specific findings. The omphalomesenteric duct fistula was confirmed through the imaging study (abdominal ultrasonography, gastrografin enema). A surgery was carried out where the remnant was resected. The patient did well and was discharged soon after without complication.

BACKGROUND: Improvements in perinatal intensive care have improved survival of extremely-low-birth-weight (ELBW) neonates, although the risk of acute abdomen has increased. The differential diagnosis resulting in abdominal surgery can be categorized into necrotizing enterocolitis (NEC), spontaneous intestinal perforation (SIP), meconium-related ileus (MRI), and meconium non-related ileus (MNRI). The purpose of this study was to review our experience with abdominal surgery for ELBW neonates, and to evaluate characteristics and prognosis according to the differential diagnosis. METHODS: Medical records of ELBW neonates treated between 2003 and 2015 were retrospectively reviewed. RESULTS: Of 805 ELBW neonates, 65 (8.1%) received abdominal surgery. The numbers of cases by disease category were 29 for NEC, 18 for SIP, 13 for MRI, and 5 for MNRI. Ostoma formation was performed in 61 (93.8%) patients; primary anastomosis without ostoma was performed in 4 (6.2%). All patients without ostoma formation experienced re-perforation of the anastomosis site. Seven patients had 30-day postoperative mortality (6 had NEC). Long-term survival of the surgical and non-surgical groups was not statistically different. NEC was a poor prognostic factor for survival outcome (P = 0.033). CONCLUSION: Abdominal surgery for ELBW neonates is feasible. Ostoma formation can lead to reduced complications compared to primary anastomosis.

Abstract OBJECTIVE To analyze the adequacy of prenatal care in a Birth Center and the causes associated with maternal and newborn transfers to the hospital. METHODS Cross-sectional study of the care provided at the only Birth Center in Rio de Janeiro, from 2009 to 2014. Statistical analyzes were based on the χ2 test and Prevalence Ratio (PR). RESULTS Suitable prenatal care was predominant (42.8%) and there was no association (p = 0.55) with the transfers. Maternal transfer is caused by the ruptured amniotic sac (PR = 2.09, 95% CI 1.62-2.70) and altered fetal heart rates (PR = 3.06, 95% CI, 2.13-4.39). Newborn transfers are associated with the presence of meconium in the amniotic fluid (PR = 2.40, 95% CI 1.30-4.43); Apgar below 7 (PR = 5.33, 95% CI 2.65-10.73); and ventilatory assistance at birth (PR = 9.41, 95% CI 5.52-16.04). CONCLUSION Complications during intrapartum care are the causes associated with transfers.

Abstract Objective: to compare the use of non-invasive midwifery care technologies (TNICEO) with the use of traditional care model practices, having as parameters the presence of meconium in the amniotic fluid and its repercussion on the newborn's vitality. Method: a cross-sectional study with secondary data of 10,219 parturients who delivered by midwives between September 2004 and October 2016. Logistic regression was used to assess Apgar> 8 Odds Ratio in exposure to noninvasive midwifery care technologies when compared to traditional care. Results: there were higher percentages of light amniotic fluid and neonates with good vitality in parturients who used only TNICEO compared with those exposed only to traditional care. Conclusion: nurse midwives' provision of TNICEO and its use by women are efficient strategies to reduce unfavorable neonatal outcomes. Implications of practice: investments in the performance of these experts is important, as their know-how to make them not medicalized through TNICEO confirms a process of humanized, safe and quality care that meets official recommendations and contributes to the change in the care model.

RESUMEN Introducción: La peritonitis meconial (PM) corresponde a una inflamación del peritoneo por una reacción química estéril producida por la presencia de meconio, secundaria a una perforación intestinal in útero. Se expone un caso real de PM cuya relevancia está dada por la baja incidencia de esta enfermedad, siendo de aproximadamente 1 caso por cada 30.000 nacidos vivos. El presente trabajo tiene como objetivo dar a conocer la presentación clásica de la PM mediante una revisión actualizada de la literatura. Caso clínico: Paciente de 21 años, primigesta, cursando embarazo de 33 + 5 semanas, con antecedentes de hipotiroidismo gestacional, es derivada al servicio de urgencia maternal por hallazgo en ecografía realizada ese mismo día: Ascitis fetal, intestino hiperecogénico, sin alteraciones en eco-Doppler fetal, hospitalizándose a paciente para estudio. Los exámenes de laboratorio, incluidos VIH y VDRL, resultaron negativos y no esclarecían una etiología. Dado hallazgos ecográficos posteriores se logra orientar el diagnóstico hacia una PM, la cual se objetivó una vez interrumpido el embarazo a la semana 38+5. Discusión: La PM representa un desafío para el médico tanto en su diagnóstico como tratamiento, lo cual está dado en parte por su baja incidencia. El caso expone la presentación más clásica de la PM, en la cual se logró establecer la importancia del diagnóstico prenatal y como este influye en el pronóstico y manejo posterior. Existe acuerdo en adoptar una conducta expectante frente a la PM e incluso esperar el inicio del parto espontaneo, si no existen otras contraindicaciones.
ABSTRACT Introduction: Meconial peritonitis (MP) corresponds to an inflammation of the peritoneum due to a sterile chemical reaction produced by the presence of meconium, secondary to a intestinal perforation in utero. We present a real case of MP whose relevance is given by the low incidence of this disease, being approximately 1 case per 30,000 live births. The present work has as objective to present the classic presentation of the MP through an updated literature review. Clinical case: A 21-year-old woman, primigravous, with a pregnancy of 33 + 5 weeks, and a history of gestational hypothyroidism, is referred to the maternal emergency service due to the following finding on ultrasound performed that same day: Fetal ascites, hyperechogenic bowel, without alterations in fetal echo-Doppler. Patient is hospitalized for study. Laboratory tests, including HIV and VDRL, were negative and did not clarify an etiology. Given later sonographic findings, the diagnosis is oriented towards MP, which was observed once the pregnancy was interrupted at week 38 + 5. Discussion: MP represents a challenge for the physician both in diagnosis and treatment, which is partly due to its low incidence. The case presents the most classic presentation of the MP, in which it was possible to establish the importance of prenatal diagnosis and how it influences the prognosis and subsequent management. There is agreement to adopt an expectant behavior towards MP and even wait for the start of spontaneous birth, if there are no other contraindications.

PURPOSE: Meconium-related ileus is common in preterm infants. Without proper management, it can cause necrotizing enterocolitis and perforation requiring emergent operation. This study was conducted to describe the efficacy and safety of ultrasound-guided Gastrografin enema at bedside for preterm infants with meconium-related ileus. METHODS: Between March 2013 and December 2014, this study enrolled preterm infants with birth weight < 1,500 g, who were diagnosed with meconium-related ileus requiring ultrasound-guided Gastrografin enema refractory to glycerin or warm saline enemas. Gastrografin was infused until it passed the ileocecal valve with ultrasound guidance at bedside. RESULTS: A total of 13 preterm infants were enrolled. Gestational age and birth weight were 28.6 weeks (range, 23.9–34.3 weeks) and 893 g (range, 610–1,440 g), respectively. Gastrografin enema was performed around postnatal day 8 (range, day 3–11). The success rate was 84.6% (11 of 13 cases). Three of these 11 infants received a second procedure, which was successful. Among 2 unsuccessful cases, one failed to pass meconium while the other required surgery due to perforation. The time required to pass meconium was 2.8±1.5 hours (range, 1–6 hours). The time until radiographic improvement was 2.8±3.4 days (range, 1–14 days) after the procedure. CONCLUSION: Ultrasound-guided Gastrografin enema at bedside as a first-line treatment to relieve meconium-related ileus was effective and safe for very low birth weight infants. We could avoid unnecessary emergent operation in preterm infants who have high postoperative morbidity and mortality. This could also avoid transporting small preterm infants to fluoroscopy suite.

BACKGROUND: In this prospective cohort study, we investigated the association between fatty acid ethyl esters (FAEEs) in meconium as biomarkers of prenatal ethanol exposure and growth deficits, as birth outcomes, that constitute several of the key cardinal features of fetal alcohol syndrome. METHODS: A total of 157 meconium samples were collected from enrolled infants within 24 hours of birth, and nine FAEEs were quantified using liquid chromatography/tandem mass spectrometry. The relationships between cumulative concentrations of nine species of FAEEs in meconium and birth parameters of growth (age-sex-specific centiles of head circumference [HC], weight, and length) and respective and combined birth outcomes of growth deficits (HC ≤ 10th centile, weight ≤ 10th centile, and length ≤ 10th centile) were determined. RESULTS: Multivariate logistic regression analysis demonstrated that higher cumulative concentrations of meconium FAEEs correlated with elevated risks for HC and length, both, 10th percentile or less (adjusted odds ratio [aOR], 2.94; 95% confidence interval [CI], 1.12–7.74; P = 0.029) and HC and weight and length, all of them, 10th percentile or less (aOR, 3.27; 95% CI, 1.12–9.59; P = 0.031). CONCLUSION: The elevated cumulative FAEEs in meconium were associated with combined growth deficits at birth, specifically HC and length, both, 10th percentile or less, which might be correlated with detrimental alcohol effects on fetal brain and bone development, suggesting a plausible alcohol-specific pattern of intrauterine growth restriction.

Introducción: La cesárea tiene por objetivo la extracción del feto a través de la incisión de las paredes del abdomen y del útero. La tasa ideal de cesárea debe oscilar entre el 10% y el 15% según la Organización Mundial de la Salud. Las complicaciones en las pacientes que habían tenido más cesáreas demostraron una morbilidad mucho mayor que las que habían tenido menos cirugías. Gran parte de esta morbilidad se concentró con placenta previa o acreta y las múltiples adherencias. Objetivos: Determinar las características clínicas en gestantes cesareadas y hallazgos transoperatorios más frecuentes en el servicio de ginecología y obstetricia, del Hospital Regional de Coronel Oviedo, 2017. Materiales y método: Estudio observacional descriptivo, con muestreo no probabilístico de casos consecutivos. La población de estudio estuvo constituida por gestantes cesareadas de distintas edades del servicio de ginecología y obstetricia del Hospital Regional de Coronel Oviedo. Resultados: La población base estuvo conformado por 224 cesareadas, de los cuales, la mediana de edad fue de 26 años, el rango etario más frecuente fue entre 20 a 24 años; de unión libre, de procedencia urbana, con estudios primarios, edad gestacional de termino, nulíparas , que presentaron controles prenatales la mayoría, con diagnóstico preoperatorio ecográfico más frecuentes de desproporción cefalopélvica, con antecedente quirúrgico obstétrico de cesárea por primera vez, y con hallazgos transoperatorios más frecuentes de circular ceñido de cordón, líquido meconial y múltiples adherencias en orden de frecuencia. Conclusión: Como antecedentes quirúrgicos obstétricos se encontró la cesárea por primera vez con mayor frecuencia en el rango de edad de 20-24 años, con hallazgos transoperatorios más frecuentes, de circular ceñido de cordón, liquido meconial y múltiples adherencias en orden de frecuencia

La Peritonitis Meconial es una patología infrecuente con una incidencia de 1/35000 nacimientos. Se caracteriza por la presencia de una perforación intestinal con salida de meconio a la cavidad abdominal que ocasionará una peritonitis química estéril. El diagnóstico es prenatal con ecografía, con calcificaciones abdominales, ascitis fetal, dilatación intestinal, seudoquistes meconiales y polihidramnios. En su etiopatogenia se encuentra la obstrucción orgánica (vólvulo, atresia o íleo meconial), etiología viral (hepatitis, varicela, citomegalovirus, parvovirus) y fibrosis quística. En nuestro caso no fue posible determinar la causa de la perforación. El objetivo de este trabajo es conocer el manejo postquirúrgico y las complicaciones.
Meconium peritonitis is a rare disease with an incidence of 1/35000 births. It is characterized by the presence of intestinal perforation with meconium out of the abdominal cavity cause a sterile chemical peritonitis. The prenatal diagnosis is with ultrasound, abdominal calcifications, ascites, bowel dilatation, meconium pseudocysts and polyhydramnios. The phatogenesis includes certain conditions: organic obstruction (volvulus, atresia or meconium ileus), viral etiology (hepatitis, chicken pox, cytomegalovirus, parvovirus) and cystic fibrosis in rare cases. In our case it was not possible to determine the cause of the perforation. The aim of this study was to determine the postoperative management and complications.

Toxic metals and deficiency/excess of trace elements can have adverse effects on health. The aim of this study was to quantify toxic metals lead, cadmium and trace elements zinc, copper, aluminium [Al] and Iron [Fe] levels in pregnant women, cord blood and meconium of new-born infants from industrial zones of Karachi, Pakistan. Analytical research was performed from 20112012 in low socio-economic pregnant mothers and newborn infants from 20 towns near Sindh Industrial Trading Estates, Federal B industrial area and Korangi industrial areas, Karachi, where environmental pollution was anticipated. Blood samples of pregnant women [n = 416], cord blood [n = 309] and meconium [n = 309] were analyzed quantitatively for metals and trace elements. Results indicated that mothers residing in steel towns were found to have the highest levels of lead. Meconium contained high levels of toxic heavy metals and trace elements compared to cord blood and maternal blood. Maternal blood toxic metals were present in high quantities. Therefore, safety measures should be taken when industrial waste is disposed of in order to prevent population contamination
