Desarrollo del dolor fetal y neonatal / Development of fetal and neonatal pain

Resumen: El dolor es el principal síntoma reportado a nivel mundial, es la principal causa de sufrimiento humano. Se considera que para que un individuo sienta dolor deben estar presentes: nociceptores, neurotransmisores del dolor, vías que llevan el estímulo al cerebro, el tálamo y conexión con la corteza. Por un tiempo se consideró que en esta etapa no se contaba con la madurez suficiente del sistema nervioso para sentir dolor; sin embargo, en la actualidad hay evidencia de que el feto presenta dolor; y su presencia altera el desarrollo del sistema nervioso. La presente revisión proporciona una visión actualizada de la ontogenia del dolor fetal y neonatal.

Abstract: Pain is the main symptom reported worldwide, it is the main cause of human suffering. It is considered that for an individual to feel pain, the following must be present: nociceptors, pain neurotransmitters, pathways that carry the stimulus to the brain, the thalamus and connection with the cortex. For a time it was considered that at this stage the nervous system was not mature enough to feel pain, however, there is currently evidence that the fetus has pain; and its presence alters the development of the nervous system. This review provides an updated view of the ontogeny of fetal and neonatal pain.

Frequency of Acid-Base Derangements Among the Neonates Admitted to the Intensive Care Unit

Background: Every year deranged acid-base physiology drives admission to a critical care arena for a vast number of neonates. The neonatal intensive care unit is a fundamental sector for the survival of high-risk newborns. The acid-base disorder must always be considered in the clinical setting. The clinician should, in most cases, be able to predict the type of acid-base imbalance before the blood gas is available. Arterial blood gases (ABG-s) are the gold standard for assessing the adequacy of oxygen delivery, ventilation, and pH. This study aimed to assess the frequency of acid-base derangements among neonates admitted to the intensive care unit. Material & Methods: This was an observational cohort study that was conducted in the Neonatal Intensive Care Unit (I.C.U.) of Dhaka Shishu Hospital, Dhaka, Bangladesh during the period from October 2009 to September 2010. In total 230 neonates admitted to the Neonatal Intensive Care Unit, after fulfilling the inclusion criteria were enrolled in this study as study subjects. For each baby, a detailed history was recorded in a questionnaire form (enclosed herewith) from the mother or other caregiver. It was filled up by the researcher himself containing history (including antenatal history), physical examinations and laboratory findings. Arterial blood gas analysis was done (in a clinical biochemistry laboratory using an automatic analyzer machine) for each neonate at admission and that report was recorded for this study. Results: Among the total study subjects, 127 newborn babies (55.2%) had acid-base imbalances. Mixed acidosis prevailed in the highest frequency (23.9%) Then metabolic acidosis cases were at 17.8% and respiratory acidosis was at 13.9%. Metabolic alkalosis and respiratory alkalosis were absent. Normal blood gas was observed in 44.3% of newborns. All the neonates with pH <7 were dead. After Chi-Square analysis (at df=1), we found a highly significant correlation between mortality outcome with pH <7.35, CO2 >45, HCO3 < 22 mol/l and Base deficit >-10. All modalities of acid-base imbalances were significantly associated with mortality. Conclusion: In this study, a significant number of neonates who were admitted to the intensive care unit, can develop acid-base derangement. Mixed acidosis was found in the highest frequency. Metabolic, respiratory and mixed acidosis all has a significant correlation with death in a NICU. Metabolic alkalosis and respiratory alkalosis were found absent at admission

Albúmina sérica predictor de resultados intrahospitalarios en pacientes admitidos a la UCIN del Hospital de la Mujer / Serum albumin predicator of intrahospital outcomes in patients admitted to the NICU of the women's hospital

INTRODUCCIÓN: En el estrés metabólico existe una sobreproducción proteica de reactantes positivos de la fase aguda y en el hígado, se frena la síntesis de otras proteínas, incluyendo la albúmina, denominadas Reactantes Negativos de la Fase Aguda. Los rangos de referencia precisos para la hipoalbuminemia patológica han resultado difíciles de determinar en los recién nacidos. MATERIAL Y MÉTODOS: Descriptivo de corte transversal en 494 recién nacidos. Se realizó un análisis exploratorio de los datos con estadística descriptiva mediante el paquete estadístico SPSS v.20. RESULTADOS: 494 neonatos fueron seleccionados, 39% fueron prematuros tardíos, 27% reportó hipoalbuminemia en sus diferentes grados que se correlacionaron con los días de internación en UCIN (p=0,0001), necesidad y tiempo en ventilador mecánico (p=0,001), con la mortalidad (p=0,001) y patología infecciosa (p=0,001). DISCUSIÓN: La incidencia acumulada de sepsis no confirmada por hemocultivo fue de 54%, La hipoalbuminemia tiene asociaciones importantes con la evolución y pronóstico en pacientes pediátricos. La PCR no tiene correlación en el estudio (p=0,232) y solo fue reactiva en 4 pacientes (0,8%). CONCLUSIONES: El nivel de albúmina sérica reportada en las primeras 24 horas de ingreso a la UCIN es un predictor para los resultados intrahospitalarios (tiempo y requerimiento de ventilación mecánica), mortalidad neonatal, sepsis neonatal y enfermedad de membrana hialina. Su determinación sérica debe ser incluida en la lista de exámenes de laboratorio solicitados a su admisión y la PCR al ingreso debe ser excluida por su pobre sensibilidad como sugiere la SIBEN.

INTRODUCTION: In metabolic stress, there is a protein overproduction of positive acute phase reactants and in the liver, the synthesis of other proteins, including albumin, called negative acute phase reactants is slowed down. Precise reference ranges for pathologic hypoalbuminemia have proven difficult to determine in neonates. MATERIAL AND METHODS: Descriptive cross section in 494 newborns. An exploratory analysis of the data with descriptive statistics was carried out using the statistical package SPSS v.20. RESULTS: 494 neonates were selected, 39% were late preterm, 27% reported hypoalbuminemia in its different degrees that correlated with the days of hospitalization in the NICU (p=0.0001), need and time on a mechanical ventilator (p=0.001), with mortality (p=0.001) and infectious pathology (p=0.001). DISCUSSION: The cumulative incidence of sepsis not confirmed by blood culture was 54%. Hypoalbuminemia has important associations with outcome and prognosis in pediatric patients. CRP does not correlate the study (p=0.232) and was only reactive in 4 patients (0.8%). CONCLUSIONS: Serum albumin level reported in the first 24 hours of NICU admission is a predictor for in-hospital outcomes (time and requirement of mechanical ventilation), neonatal mortality, neonatal sepsis, and hyaline membrane disease. Its serum determination should be included in the list of laboratory tests requested upon admission and the PCR upon admission should be excluded due to its poor sensitivity, as suggested by SIBEN.

Bacteriological profile and antibiotic susceptibility of blood culture from neonates in GMERS Medical College, Gandhinagar

Background: Neonatal sepsis refers to an infection involving bloodstream in newborn infants <28 days old. Neonatal sepsis contributes substantially to neonatal morbidity and mortality and is an ongoing major global public health challenge. Aim and Objectives: The objectives of this study were to study bacteriological profile and antibiotic susceptibility of blood culture from neonates in GMERS Medical College, Gandhinagar. Materials and Methods: For culture and antimicrobial susceptibility test, blood samples were taken from the suspected cases admitted in NICU. Total 271 blood culture positive NICU admitted patient with septicemia were taken in this study. Results: Total 271 septicemic neonates having blood culture positive septicemia, neonatal septicemia was predominantly caused by Gram-negative organism Klebsiella pneumoniae (40.60%). Among the all Gram-negative organisms, Piperacillin/Tazobactam was most sensitive drug followed by Meropenem. Moreover, for the all Gram-positive organism, vancomycin and linezolid were the most sensitive drugs. Conclusion: Neonatal septicemia is major cause of morbidity and mortality in India. Multiple antibiotic resistance among the isolates worsen the condition more. A high level of suspicions is needed on clinical ground for diagnosis. Judicious use of antibiotics should be promoted.

Screening status of neonatal fundus disease and its influencing factors in Longhua district, Shenzhen / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the screening status of neonatal fundus disease and the related influencing factors of common fundus retinal hemorrhage in Longhua District of Shenzhen, so as to provide references for the prevention, screening and intervention of neonatal fundus disease in clinical practice.METHODS: A total of 3 101 neonates who received fundus screening in the People's Hospital of Longhua, Shenzen from September 2019 to October 2022 were selected as research objects. The screening results were summarized, and the risk factors for neonatal retinal hemorrhage were analyzed by Logistic regression model.RESULTS: The detection rate of neonatal fundus abnormalities was 12.71%, and the detection rate of neonatal retinal hemorrhage was the highest(12.19%). The other types of fundus abnormalities included periretinal white focus, chromatosis, pigment shedding, choroid coloboma and nystagmus. Hemorrhage grade I accounted for the largest proportion of 378 neonates with retinal hemorrhage(75.66%). Follow-up found that different grades of retinal hemorrhage could be automatically absorbed over time without excessive intervention. Logistic analysis suggested that spontaneous delivery [OR=3.180, 95%CI(1.543～6.555)], twin pregnancy [OR=2.119, 95%CI(1.121～4.007)] and umbilical cord round the neck [OR=1.547, 95%CI(1.239～1.930)] were risk factors affecting neonatal retinal hemorrhage.CONCLUSION: Retinal hemorrhage is the most common type of fundus abnormalities in neonates. Spontaneous delivery, twin pregnancy and umbilical cord around the neck are risk factors of retinal hemorrhage. It is recommended that pay attention to the above factors and choose appropriate intervention means to avoid serious fundus complications.

Dynamic changes and influencing factors of vitamin K levels in neonates / 中国新生儿科杂志

Objective:To study the incidences of vitamin K 1 and K 2 deficiency (VKD) in umbilical cord blood (UBC) of neonates and the dynamic changes and influencing factors of serum vitamin K 1 levels after preventive vitamin K 1 supplementation. Methods:From January 2021 to June 2022, neonates born in the Obstetrics Department of our hospital were prospectively enrolled and the levels of vitamin K 1 and K 2 in UBC and serum vitamin K 1 levels at 14 d and 28 d after vitamin K 1 supplementation were measured. The neonates were assigned into hospitalization group and healthy group and further assigned into early-preterm, late-preterm and full-term groups based on gestational age (GA). The incidences of VKD of different GA were studied. Dynamic changes of vitamin K 1 levels were calculated. Multivariate logistic regression was used to analyze the influencing factors of vitamin K 1 levels in hospitalization group at 28 d. Results:A total of 100 neonates were included. 80 neonates were hospitalized, including 25 early-preterm, 25 late-preterm and 30 full-term. 20 were healthy full-term neonates. No significant differences existed in the incidences of VKD of different GA ( P>0.05), however, the overall incidences were high (82.0% and 84.0%, respectively). After preventive vitamin K 1 supplementation, the levels of vitamin K 1 in full-term and preterm groups at 14 d were higher than at birth and 28 d. The levels of vitamin K 1 in hospitalized full-term neonates at 14 d and 28 d were higher than hospitalized preterm neonates. The levels of vitamin K 1 at 28 d in healthy group was significantly higher than hospitalization group ( P<0.05). Multivariate logistic regression analysis showed that maternal complications during pregnancy ( OR=5.889, 95% CI 1.621-21.399, P=0.007) and neonatal antibiotic use ( OR=5.615, 95% CI 1.833-17.221, P=0.003) were risk factors and formula feeding ( OR=0.389, 95% CI 0.193-0.786, P=0.008) was a protective factor for VKD. Conclusions:VKD is common in neonates. The serum vitamin K 1 level increases significantly after preventive vitamin K 1 supplementation. The vitamin K 1 levels of hospitalized full-term neonates at 14 d and 28 d are higher than hospitalized preterm neonates. The levels of vitamin K 1 at 28 d in hospitalized neonates are influenced by feeding methods, maternal complications during pregnancy and neonatal antibiotic use.

Neonatal nonketotic hyperglycinemia: a case report and literature review / 中国新生儿科杂志

Objective:To study the phenotypes and genotypes of neonatal nonketotic hyperglycinemia (NKH).Methods:A neonate with severe NKH admitted to our hospital was retrospectively analyzed. Using keywords 'glycine cleavage enzyme', 'glycine decarboxylase', 'nonketotic hyperglycinemia' and 'glycine encephalopathy' (both in Chinese and English), multiple medical databases were searched until December 31, 2022. The clinical phenotypes and genotypes of neonatal NKH were summarized.Results:For our case, the neonate was lethargy and had no appetite on the second day of life, followed by recurrent seizures and irregular breathing, requiring mechanical ventilation. She died at 3 weeks of age. Two compound heterozygous variants were found in GLDC gene from whole exome sequencing , one was c.848C>G(p.A283G) of maternal origin and one was c.1607G>A(p.R536Q) of paternal origin. The former was a novel mutation. A total of 54 cases (including this case) were collected. The main clinical manifestations included poor feeding, decreased muscle tone, hiccups, progressive lethargy, irregular breathing, apnea and neonatal seizures. 42 cases (77.8%) had GLDC gene mutations, 9 cases (16.7%) had AMT gene mutations, 2 cases (3.7%) had LIAS gene mutations and 1 case (1.9%) had GCSH gene mutations. Conclusions:Neurological manifestations are most common in neonatal NKH with wide clinical variations. GLDC gene mutations are the predominant pathogenic mutations.

The correlation of bone metabolism biomarkers in newborn twins and their pregnant mothers / 中国新生儿科杂志

Objective:To study the correlation of bone metabolism biomarkers between newborn twins and their mothers during pregnancy.Methods:From January 1, 2018 to June 30, 2022, newborn twins with mild symptoms admitted to the neonatal department of our hospital were retrospectively reviewed. The clinical data of the twins and their mothers were collected, including bone metabolism biomarkers of the twins within 3 d after birth and their mothers within last month during pregnancy. The twins were assigned into different groups according to gestational age(GA), birth weight(BW), the relationship between BW and GA(appropriate for GA(AGA),small for GA(SGA) and large for GA(LGA), birth season, gender, and the mothers' age, ethnicity, pre-delivery body mass index (BMI), gestational BMI increase, number of births and chorionic properties. The correlations of bone metabolism biomarkers between the twins and their mothers were analyzed.Results:A total of 302 pairs of twins were included. The incidence of insufficient or deficient serum 25-(OH)D 3 was 97.4% among the mothers, and 87.7% among the twins. The levels of blood phosphorus ( r=0.262, P<0.001) and 25-(OH)D 3 ( r=0.239, P=0.002) in mothers were positively correlated with the twin with larger BW. No significant differences existed in 25-(OH)D 3 between genders, AGA,SGA and LGA, birth season, and mothers' age, ethnicity, pre-delivery BMI, gestational BMI increase and chorionic properties( P>0.05). 25-(OH)D 3 in the twins were positively correlated with BW and 25-(OH)D 3 of mothers before delivery ( P<0.05) and negatively correlated with number of births ( P<0.05). Conclusions:In most mothers and their newborn twins, 25-(OH)D 3 are insufficient or deficient. The levels of blood phosphorus and 25-(OH) D 3 are correlated between the newborns and their mothers. The lower the BW of the newborn, the more times the mother give birth and the lower the mother's pre-delivery 25-(OH)D 3 level, the lower the newborn's 25-(OH)D 3 level.

Clinical features and risk factors of pulmonary hemorrhage in extremely preterm infants / 中国新生儿科杂志

Objective:To study the clinical features and risk factors of pulmonary hemorrhage in extremely preterm (EPT) infants.Methods:From February 2018 to January 2022, EPT infants admitted to NICU of our hospital and diagnosed with pulmonary hemorrhage were retrospectively assigned into the observation group and those without pulmonary hemorrhage were assigned into the control group. Univariate analysis and multivariate logistic regression analysis were used to compare the clinical features and determine risk factors of pulmonary hemorrhage in EPT infants.Results:A total of 114 EPT infants were included, including 28 cases (24.6%) in the observation group with pulmonary hemorrhage and 86 cases in the control group. Pulmonary hemorrhage mainly occurred within the first week after birth. Univariate analysis showed that the observation group had higher incidences of following events than the control group: birth asphyxia, delivery room intubation, severe respiratory distress syndrome, hyperglycemia, thrombocytopenia, severe acidosis, shock, score for neonatal acute physiology with perinatal extension-Ⅱ (SNAPPE-Ⅱ) ≥37 and the highest lactate level. Birth weight was lower in the observation group than the control group ( P<0.05). Logistic regression analysis showed that SNAPPE-Ⅱ≥37, shock and hyperglycemia were risk factors of pulmonary hemorrhage ( OR=4.081, 4.610 and 3.355, respectively, all P<0.05). The incidences of mortality and intracranial hemorrhage in the observation group were higher than the control group. The duration of mechanical ventilation in the observation group was longer than the control group ( P<0.05). No significant differences existed in the duration of nasal continuous positive airway pressure, assist mechanical ventilation and total oxygen use, the incidences of grade Ⅱ-Ⅲ bronchopulmonary dysplasia, retinopathy of prematurity and the length of hospital stay ( P>0.05). Conclusions:SNAPPE-Ⅱ≥37, shock and hyperglycemia are early risk factors for pulmonary hemorrhage in EPT infants. EPT infants with pulmonary hemorrhage have higher incidences of mortality and intracranial hemorrhage, requiring longer periods of mechanical ventilation.

The early use of iNO in extremely premature neonates with refractory hypoxic respiratory failure / 中国新生儿科杂志

Objective:To study the early use of inhaled nitric oxide (iNO) as a rescue therapy in extremely premature infants (EPIs) with refractory hypoxic respiratory failure (HRF).Methods:Between January 2021 and December 2021, EPIs with refractory HRF receiving iNO within the first week of life in our NICU were enrolled. Their clinical characteristics and outcomes were retrospectively analyzed.Results:A total of 11 EPIs were included with 5 males and 6 females. The median gestational age (GA) was 24(22.6, 25.2) weeks. The median birth weight (BW) was 580(490, 770) g. The most common primary diagnoses were moderate/severe respiratory distress syndrome (RDS) (5/11) and early-onset sepsis (3/11). The median age starting iNO therapy was 6.5(4.5, 34.0)h and the median duration of iNO was 24(12, 36)h. The median iNO starting dose was 5(5, 8) ppm and the therapeutic range was 5-20 ppm. Therapeutic efficacy was defined as ≥30% FiO 2 reduction after 6 h of iNO treatment. The treatment was effective in 8 cases. The oxygenation index (OI) decreased more than 10% from baseline 1 h after initiation in 9 patients and in all 11 patients after 12 h of iNO. The reduction of OI was more prominent in EPIs with a higher OI at baseline. Of the 11 patients, 8 survived, 1 died and 2 abandoned further treatments. Conclusions:As an early rescue therapy for EPIs with refractory HRF, iNO can improve oxygenation without obvious short-term adverse effects.

Avaliação audiológica em bebês nascidos de mães que tiveram covid-19 no período gestacional / Audiological assessment in babies born to mothers who had covid-19 during gestation / Evaluación audiológica en bebés nacidos de madres que tenían covid-19 durante la gestación

Introdução: No final de dezembro de 2019, um grupo de casos inexplicáveis de pneumonia foi relatado em Wuhan, China. Alguns dias depois, o agente causador dessa misteriosa doença foi identificado como um novo coronavírus que se disseminou de forma rápida. As infecções maternas, contraídas antes ou durante a gravidez, podem ser transmitidas ao feto, durante a gestação (infecção congênita), durante o parto (infecção perinatal) e pela amamentação (infecção pós-natal) e podem causar danos ao feto ou ao recém-nascido. Objetivo: descrever a avaliação audiológica realizada em uma série de crianças cujas mães tiveram COVID-19, em sua forma leve, no período gestacional. Metodologia: Para a avaliação audiológica foram realizadas a anamnese e os exames de emissões otoacústicas por produto de distorção, nas frequências de 1,5 a 12KHz e pontencial auditivo de tronco encefálico por click. Resultados: A amostra foi composta por 47 recém-nascidos recém-nascidos. Os resultados dos testes das emissões otoacústicas evocadas por produto de distorção indicaram funcionalidade das estruturas avaliadas apontando normalidade da função coclear com nível de resposta adequado para a média de resultados obtidos até a frequência de 11kHz para a amplitude de resposta e para a relação sinal-ruído. Foi possível encontrar em toda a amostra a presença das ondas I, III e V na intensidade de 80dBHL e presença da onda V nas intensidades de 50 e 35dBHL bilateralmente. Conclusão: Não foi estabelecida uma correlação direta da infecção materna pelo vírus da covid-19 com os achados audiológicos nos recém- nascidos. Cabe mencionar que esse foi um estudo preliminar e que essas crianças precisam continuar em acompanhamento para investigação de futuros desfechos tardios no aparelho auditivo.

Introduction: In late December 2019, a cluster of unexplained pneumonia cases was reported in Wuhan, China. A few days later, the causative agent of this mysterious disease was identified as a new coronavirus that spread rapidly. Maternal infections, contracted before or during pregnancy, can be transmitted to the fetus during pregnancy (congenital infection), during childbirth (perinatal infection) and through breastfeeding (postnatal infection) and can cause harm to the fetus or newborn. -born. Objective: to describe the audiological evaluation carried out in a series of children whose mothers had COVID-19, in its mild form, during the gestational period. Methodology: For the audiological evaluation, anamnesis and distortion product otoacoustic emissions tests were carried out, at frequencies from 1.5 to 12KHz and brainstem auditory potential by click. Results: The sample consisted of 47 newborns. The results of the distortion product evoked otoacoustic emissions tests indicated functionality of the evaluated structures, pointing to normal cochlear function with an adequate response level for the average of results obtained up to a frequency of 11kHz for the response amplitude and the signal-to-noise ratio. . It was possible to find in the entire sample the presence of waves I, III and V at an intensity of 80dBHL and the presence of wave V at intensities of 50 and 35dBHL bilaterally. Conclusion: A direct correlation between maternal infection by the Covid-19 virus and audiological findings in newborns was not established. It is worth mentioning that this was a preliminary study and that these children need to continue being monitored to investigate future late outcomes with the hearing aid.

Métodos para la detección de cardiopatías congénitas en neonatos

Las cardiopatías congénitas conforman el grupo de las malformaciones innatas más comunes, siendo vital su detección temprana. Este estudio tuvo por objetivo caracterizar las publicaciones acerca de los métodos para la detección de cardiopatías congénitas en neonatos a partir de tres categorías: las características generales de las investigaciones, la información de los investigadores y la definición y características de las metodologías practicadas. Para tal efecto, y con ayuda de tablas dinámicas de MS Excel 16.52 y el software VOSviewer 1.6.17, se llevó a cabo una revisión sistematizada que permitió recopilar 63 artículos publicados entre 2010 y 2021 en Scopus, Web of Science y PubMed. Los hallazgos evidencian que la producción académica ha ido incrementándose desde el 2018, teniendo a Estados Unidos a la vanguardia de esta y siendo la ecocardiografía y la oximetría los procedimientos más estudiados. La comparación entre las metodologías advierte que la detección por oximetría es la más destacable, en cuanto a los factores evaluados. Esta investigación abre nuevas líneas de indagación en la materia con la finalidad de desarrollar y aplicar nuevas metodologías o perfeccionar las ya existentes para que se ajusten a las necesidades de la población.

Congenital heart disease is one of the most common innate malformations, and early detection is vital. The aim of this study was to characterize the publications on methods for the detection of congenital heart disease in neonates based on three categories: the general characteristics of the investigations, the information provided by the researchers, and the definition and characteristics of the methodologies used. For this purpose, and with the help of MS Excel 16.52 pivot tables and VOSviewer 1.6.17 software, a systematized review was carried out that allowed us to compile 63 articles published between 2010 and 2021 in Scopus, Web of Science and PubMed. The findings evidence that academic production has been increasing since 2018, with the United States being at the forefront of this and echocardiography and oximetry being the most studied procedures. The comparison between the methodologies warns that detection by oximetry is the most outstanding in terms of the factors evaluated. This research opens up new lines of investigation in the field with the aim of developing and applying new methodologies or improving existing ones to meet the needs of the population.

Presencia de dientes natales o neonatales en pacientes pediátricos con y sin labio y paladar hendido / Presence of natal or neonatal teeth in pediatric patients with and without cleft lip and palate

Objetivo: determinar la presencia de dientes natales y neonatales en pacientes pediátricos con/sin labio y paladar hendido, que han sido atendidos en un hospital de tercer nivel de 2019-2020, mediante la revisión de expedientes clínicos. Métodos: estudio retrospectivo, observacional descriptivo y revisión de expedientes de pacientes atendidos de 2019-2020. Resultados: en el hospital de tercer nivel se reportan 15 nacimientos por día, 5475 al año. De estos, se identificaron 110 bebés con dientes natales revisados en cuneros, 84 pacientes con labio y paladar hendido en consulta, con una relación de 1:50, mayor prevalencia en dientes inferiores centrales. Su manejo fue resuelto con extracciones en todos los casos, debido a la movilidad dental y el riesgo potencial en la alimentación por bronco aspiración del paciente. Conclusiones: los dientes neonatales y natales se encontraron con mayor frecuencia en pacientes de unidades de tercer nivel consultadas, posiblemente por ser centros de referencia. Se identificó confusión en el personal de salud respecto a la nomenclatura de los dientes que presentan los pacientes al nacer (dientes neonatales), además, se encontró una alta frecuencia de dientes natales en los pacientes estudiados en este caso. La relevancia se encuentra en que no hay estudios que definan la razón del porqué los pacientes nacen con dientes. La respuesta puede estar relacionada con un factor hormonal de la madre, aunque no se ha encontrado evidencia sobre esto. Mientras que los dientes neonatales

Objective: To determine the presence of natal and neonatal teeth in pediatric patients with/without cleft lip and palate who have been seen in a tertiary hospital from 2019-2020, by reviewing clinical records. Methods: Retrospective, descriptive observational study and review of patient records from 2019-2020. Results: In the third level hospital 15 births are reported per day, 5475 per year. Of these, 110 babies with natal teeth were identified in the nursery, 84 patients with cleft lip and palate were identified in consultation, with a ratio of 1:50, with a higher prevalence in lower central teeth. Their management was solved with extractions in all cases, due to tooth mobility and the potential risk in feeding by bronchial aspiration of the patient. Conclusions: Neonatal and natal teeth were found more frequently in patients in the tertiary level units consulted, possibly because they were referral centers. Confusion was identified among health personnel regarding the nomenclature of the teeth that patients present at birth (neonatal teeth), and a high frequency of natal teeth was found in the patients studied in this case. The relevance lies in the fact that there are no studies that define the reason why patients are born with teeth. The answer may be related to a hormonal factor of the mother, although no evidence on this has been found. While neonatal teeth occurred less frequently, there are no conclusive studies either.

Incidence of blood culture-related sepsis in neonates and antibiotics sensitivity of implicated organisms in a secondary healthcare facility in Ghana

Objective: We determined the incidence of blood culture-related sepsis, causative bacteria, and antibiotics sensitivity among newborn babies with suggestive signs of sepsis admitted at the Upper East Regional Hospital in Bolgatanga, Ghana. Design: Prospective cross-sectional study Setting: Newborn Care Unit of the Upper East Regional Hospital, Bolgatanga Participants: Neonates admitted to the Newborn Care Unit from August 2019 to August 2020 with signs of sepsis Main outcome measures: Organisms isolated from blood cultures and sensitivity of isolated organisms to antibiotics. Results: The study included two hundred and seventy-six (276) patients. Laboratory confirmed sepsis was 13.4% (37/276). Early onset sepsis was 3.3% (9/276), while late-onset sepsis was 10.1% (28/276). The most common clinical signs associated with positive culture cases were temperature instability (35.5%), poor feeding (14.5%), neonatal jaundice (11.3%), vomiting (9.7%), and respiratory distress (8.1%). Staphylococcus aureus and Staphylococcus epidermidis were the most common bacterial isolates (46% and 32%, respectively). There was no relationship between independent variables and blood culture confirmed sepsis. Antibiotics to which isolates were most resistant included flucloxacillin 4/4, penicillin 14/15, ampicillin 16/18, and tetracycline 23/28. Bacterial isolates were most sensitive to amikacin 16/16, levofloxacin 5/5, erythromycin 8/8, cefazolin 7/8, and ciprofloxacin 18/24. Conclusion: Late-onset sepsis is a common sepsis category, and the implicated microorganisms are resistant to commonly prescribed antibiotics.

Antibiotic safety among neonates and paediatrics in a public hospital: KwaZulu-Natal

Background: The World Health Organization (WHO) guidelines recommend the empiric treatment of infections before definitive treatment begins. However, ethical concerns limit the availability of clinical trials in neonates and paediatrics to fully ascertain the safety profile of antibiotics in these populations. Aim: This study aimed to quantify the use of antibiotics among neonates and paediatrics and commented on the use, rationale and appropriateness of antibiotics prescribed. Setting: A secondary level public sector hospital located in Durban, KwaZulu-Natal. Methods: Demographic and treatment information of neonates and paediatrics were collected retrospectively from January 2022 to June 2022. Data were obtained from patient files and extracted for analysis using Microsoft Excel®. Analytical and descriptive statistics were used to analyse patient demographics and treatment variables. Results: A total of 568 antibiotics, issued to 389 patients, were reviewed. Penicillins (40.1%), aminoglycosides (24.3%) and combination penicillin-beta-lactam inhibitors (23.3%) were identified as the most frequently prescribed antibiotics for inpatients. Most antibiotics prescribed to inpatients were for complications associated with pre-term birth (66.9%). Combination penicillin-beta-lactam inhibitors (34.7%), penicillins (29.5%) and cephalosporins (29.5%) were the most frequently prescribed antibiotics to outpatients. A correlation was found between the route of administration and the duration of therapy; the intravenous route (63.6%) was preferred over the oral route (36.4%) for administration. Conclusion: Many broad-spectrum antibiotics were prescribed, thus increasing the risk of resistance. Antibiotics were being prescribed according to the guidelines; however, there is still a need for therapeutic drug monitoring to ensure the continuation of rational drug use. Contribution: There was evidence of rational use of antibiotics in the public hospital (KwaZulu-Natal), in keeping with economic and availability factors.

Audit of emergency obstetric referrals at a Tertiary Center in Kano

Introduction: Maternal and perinatal deaths could be prevented if functional referral systems are in place to allow pregnant women to get appropriate services when complications occur. Methodology: The study was a 1-year retrospective study of obstetric referrals in Aminu Kano Teaching hospital, from 1st January to 31st December 2019. Records of all emergency obstetrics patients referred to the hospital for 1 year were reviewed. A structured proforma was used to extract information such as sociodemographic characteristics of the patients, indications for referral, and pre-referral treatment. The care given at the receiving hospital was extracted from the patients' folders. An Audit standard was developed and the findings were compared with the standards in order to determine how the referral system in the study area perform in relation to the standard. Results: There were total of 180 referrals, the mean age of the women was 28.5 ± 6.3 years. Majority (52%) of the patients were referred from Secondary Centres and only 10% were transported with an ambulance. The most common diagnosis at the time of referral was severe preeclampsia. More than half of the patients (63%) had to wait for 30 to 60 minutes before they see a doctor. All the patients were offered high quality care and majority (70%) were delivered via caesarean section. Conclusion: There were lapses in the management of patients before referral; failure to identify high risk conditions, delay in referral, and lack of treatment during transit to the referral centre.

Risk factors of red blood cell infusion in very low/ultra-low birth weight neonates with respiratory distress syndrome / 中国输血杂志

【Objective】 To investigate the risk factors of red blood cell transfusion frequency (fRBCT) toward newborns with very/extremely low birth weight (V/ELBW) who experienced 57 days, >2.75 days and >23.75 days. 【Conclusion】 Increased fRBCT may complicate V/ELBW NRDS newborns who experienced <32 weeks of gestational age with NEC, hematosepsis, BPD and ROP. Duration of hospital stay, invasive ventilation and IVN are relatively effective predictive indicators for whether such cases have undergone ≥3 red blood cell transfusions throughout their hospitalization.

The myocardial protection of HTK versus del Nido cardioplegia solutions in neonates with surgeries for transposition of the great arteries : A propensity score matching study / 中国胸心血管外科临床杂志

@#Objective    To compare and analyze the effect of myocardial protection between HTK and del Nido cardioplegia solutions in neonates with surgeries for transposition of the great arteries. Methods    The clinical data of 208 neonates with complete transposition of the great arteries in our institution from 2014 to 2020 were retrospectively analyzed. According to the cardioplegia solutions utilized in the operations, the patients were divided into two groups: a HTK group and a del Nido group. Propensity score matching was conducted to eliminate the biases. The cardiopulmonary bypass time, aortic cross-clamping time, total amount of cardioplegia solutions, transfusion frequency of cardioplegia, ICU stay time, mechanical support time, inotropic score, hospital stay, left ventricular ejection fraction, N-terminal proBNP and troponin I were compared and analyzed between the two groups after matching. Results    After 1:1 propensity score matching, a total of 54 patients were analyzed with 27 patients in each group. In the HTK group, there were 22 males and 5 females with a median age of 7.0 (2.0, 11.0) d. In the del Nido group, there were 23 males and 4 females with a median age of 8.0 (3.0, 11.0) d. A total of 3 children died after the surgery: 2 (7.4%) patients in the HTK group and 1 (3.7%) patient in the del Nido group. There was no significant difference in hospital mortality between the two groups (P=1.000). The total amount of cardioplegia solutions in the HTK group was significantly higher than that of del Nido group (P<0.001). Transfusion frequency of cardioplegia in del Nido group was significantly higher than that of the HTK group (P=0.043). There was no significant difference in the postoperative ICU time, mechanical support time, length of hospital stay, inotropic score, left ventricular ejection fraction, N-terminal B-type natriuretic peptide precursor or troponin I between the two groups (P>0.05). Conclusion    For neonates with surgeries for complete transposition of the great arteries, HTK cardioplegia solutions can provide effective and safe myocardial protection, which is similar to del Nido cardioplegia solutions.

Outcome of Early Versus Late Surfactant Therapy in Preterm Neonates with Respiratory Distress Syndrome at a Tertiary Care Centre

Background: Respiratory distress syndrome (RDS) or hyaline membrane disease (HMD), has been recognized as the most common co-morbidity of prematurity. Prematurity and RDS largely contribute to early neonatal morbidity and mortality. With adequate antenatal steroid and early continuous positive airway pressure, early surfactant therapy improve survival outcome.Material & Methods:Prospective interventional study included newborns with prematurity 28-36 weeks(GA) with clinical Respiratory distress syndrome and birth weight(BW)>650 gm. All subjects were preferably provided early surfactant therapy (within 2hours after birth). Surfactant (survanta) was delivered by INSURE technique (Intubate- Surfactant administration- Extubate) and only those who required further respiratory support were ventilated. Records on birth weight, gestational age, timing of therapy (early/late), sepsis, complications, and survival/death outcome were collected and data was analyzed using SSPS version 20 software.Results:Out of 76 neonates (42 male, 34 female), 46 received early surfactant therapy and 30 obtained it late; Although mortality was observed with both early(36.66%) and late therapy(63.33%), there was significantly higher survival with early therapy. higher mortality occurred in lower Birth weight(LBW) /Gestational age (GA) subgroups. Culture positive sepsis was found in 52.6% with higher association with late therapy . Hypotension was most common complication with late intervention , whereas there was no difference for pulmonary haemorrhage or apnea.Conclusion:Early surfactant administration improved survival with minimal complications in RDS except for extremely premature/LBW babies.

Study of Clinical and Outcome Profile of Neonatal Sepsis with Thrombocytopenia Patients Admitted at Tertiary health care Centre Nanded

Background: Thrombocytopenia is a frequent problem in neonatal sepsis and is among the most predic?ve, independent risk factors for sepsis-associated mortality. The present study was undertaken to correlate neonatal sepsis and thrombocytopenia in terms of severity, clinical course, organism specificity and outcome. Method: Total 384 neonates age <28 days with sepsis and thrombocytopenia were studied and analyzed with their clinical profile, symptoms, lab findings and outcomes. Results: Male babies (55.86%), age <72 hrs (80.35%), preterm (68.70%) and LBW babies (85.58%) were more prone to sepsis. Maternal fever (67.44%), foul smelling liquor (53.79%) and PROM >18 hrs (66.74%) make babies more prone to neonatal sepsis. The Commonest clinical features were not accepting feed (69.95%), lethargy (67.85%) and breathing difficulty (79.04%). Early onset sepsis (82.54%) and probable sepsis (40.26%) were more common and associated with preterm and LBW babies. Leucocytosis was seen in 64.57%, thrombocytopenia moderate degree 45.67% and severe degree 34.65%, MPV >12 69.11%, ANC <1800 47.50%, micro ESR >15 mm 72.16% and CRP posi?vity 28.60%. Severe degree thrombocytopenia (<50000) was more common with PROM >18 hrs (83.02%), maternal fever (83.09%) and gram-nega?ve organism(61.29%). Leucopenia (<4000) was more common with maternal fever (75.79%), proven sepsis (43.16%) and gram-nega?ve organism (70.31%). Severe degree thrombocytopenia (61.29%), leucopenia (70.31%) and mortality (64.51%) were more commonly associated with gram-nega?ve organism. Outcome was bad with severe degree of thrombocytopenia (62.32%), leucopenia (73.91%), and gram-nega?ve organism (64.51%). Conclusion: Proper antenatal mother care, hygiene and early evalua?on for illness can prevent early onset of sepsis in neonates. Severity of degree of thrombocytopenia directly propor?onal to the worst outcome.
