Treatment Options for Cyclic Vomiting Syndrome: A Real-World, Single-Center Experience with Systematic Literature Review and Meta-Analysis.

The optimal therapeutic management of cyclic vomiting syndrome (CVS) remains elusive. The objective of this study was to document our clinical experience in the Pediatric Department of San Marco Hospital and to survey the literature on pediatric CVS treatment, aiming to update the guidance on the most effective treatment strategies for this not-so-uncommon condition. Data from 70 patients with CVS, admitted to our Pediatric Department between September 2011 and December 2021, were aggregated and included in the study. A systematic review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The quality of the included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool and the A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2) method. Treatment responses, as observed both in the literature and in our own experience, are variable. In our cohort, topiramate demonstrated superiority over other pharmacological treatments, exhibiting an efficacy of 85% in the patients treated. A universally accepted treatment protocol for pediatric CVS has yet to be established. The efficacy of first-line treatments is generally suboptimal, suggesting that topiramate might serve as a safe and effective primary therapeutic option for pediatric CVS.

Thrombotic events in children and adolescent patients with SARS-CoV-2 infection: a systematic review with meta-analysis on incidence and management.

OBJECTIVES: The present paper aimed to study the available literature on the hypercoagulability state of pediatric patients affected by COVID-19, and the current management of thrombosis in these patients, considering that no guidelines have been published since now in this age group. METHODS: N 244 titles were screened using the selected MESH words, 180 abstracts and 120 full texts were read, 12 articles were included, and four were analyzed by meta-analysis. RESULTS: Over 1128 COVID-19 positive patients, nearly half of them developed inflammatory sequelae, and 7.35% (40 patients over 544 who developed MIS-C) had thrombotic events. Less than 50% of patients with inflammatory disease were under anticoagulant prophylactic treatment, and doses of anticoagulant protocols vary from different centers. Thrombotic events prevented after the start of unfractionated heparin (UFH) therapy, even if 1.06% (4 patients) died. Only two patients presented complications after anticoagulant treatment, with non-fatal bleeding after UFH treatment. No other complications were reported. No difference in the incidence of thrombotic events between patients under prophylactic low molecular weight heparin (LMWH) and those without was found in meta-analysis (p = 0.32). CONCLUSIONS: Little is known on the incidence and management of hyper coagulopathy in pediatric COVID-19 infection. Further studies have to clarify this topic.

Pulse Oximetry Saturation (Spo2) Monitoring in the Neonatal Intensive Care Unit (NICU): The Challenge for Providers: A Systematic Review.

BACKGROUND: In the neonatal intensive care unit (NICU), maintaining an oxygenation level that avoids both hypoxemia and hyperoxemia is challenging. Pulse oximetry has become fundamental for noninvasive monitoring of saturation of peripheral oxygen (Spo2) in preterm newborns. PURPOSE: The aim of this systematic review is to determine Spo2 target values in order to avoid hypoxemia or hyperoxemia and complications arising from these. METHOD AND SEARCH STRATEGY: For this systematic review, articles were audited from 2010 to 2020 using the PRISMA guidelines. PubMed, MEDLINE, Google Scholar, and Scopus databases were used, and search terms were related to use of pulse oximetry in the NICU. RESULTS: The result showed that 12 of 20 (60%) studies focused on target values but without a unanimous agreement on values, although 5 of 12 studies (41.66%) suggested a lower value target of 85% and 4 of 12 studies (33.33%) recommended 95% as the higher target value. Other authors showed no difference in the incidence of adverse events comparing different target values and focused the importance more on the fluctuation of the value than on the target value itself. IMPLICATION FOR PRACTICE: Reaching a balance in the oxygen administration so as to avoid potential complications associated with hypoxemia or hyperoxemia is a challenge for the clinicians. IMPLICATION FOR RESEARCH: Further studies on fluctuation of Spo2 comparing different starting targets could better clarify the role of fluctuations and the absolute target values.Video Abstract available at:https://journals.na.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?autoPlay=false&videoId=49.

Observational study on the efficiency of Neonatal Emergency Transport in reducing mortality and morbidity indexes in Sicily.

In these last 25 years, the Neonatal Emergency Transport (NET) service has been widely improved in Italy. To date, all National areas are covered by a NET service; 53 NET centers have been activated in all the Italian territory. Herein, the authors present an observational study to evaluate the rate of infantile mortality after introduction of NET in Sicily, and to study the efficiency of this service in reducing these rates of mortality in vulnerable neonates, transported from primary care birth centers to tertiary facilities to undergo to specialized NICU assistance. All neonates who required an emergency transport by NETS were included. No exclusions criteria were applied. Demographic and regional infantile mortality data, expressed as infant mortality rate, were selected by the official government database (ISTAT- National Statistic Institute- http://www.istat.it ). All data were respectively divided into three groups: data concerning transport, clinical condition, and mortality of the transported patients. We transported by NET 325 neonates. The analysis of the infant mortality rate (per 1.000 live births) in Catania from 2016 to 2018 was reduced compared to the same rate calculated before NETS activation (4.41 index before 2016 vs 4.17 index after 2016). These data showed an increase in other provinces (Enna, Caltanissetta, and Agrigento). 61% of neonates showed a respiratory disease. During the study period the proportion of neonates with a Mortality Index for Neonatal Transportation-MINT < 6 has been reduced, while there was an increase of neonates with higher Transport Risk Index of Physiologic Stability-TRIPS score results. The slight decrease of infantile mortality in Catania during the first three years after introduction of NET follows the same trend of all Italian territories, showing the importance of this service in reducing infantile mortality.

Monogenic Syndromes with Congenital Heart Diseases in Newborns (Diagnostic Clues for Neonatologists): A Critical Analysis with Systematic Literature Review.

Congenital heart disease (CHD), the most common major congenital anomaly, is associated with a genetic syndrome (chromosomal anomalies, genomic disorders, or monogenic disease) in 30% of patients. The aim of this systematic review was to evaluate if, in the neonatal setting, clinical clues that orient the diagnostic path can be identified. For this purpose, we revised the most frequent dysmorphic features described in newborns with CHD, comparing those associated with monogenic syndromes (MSG) with the ones reported in newborns with genomic disorders. For this systematic review according to PRISMA statement, we used PubMed, Medline, Google Scholar, Scopus database, and search terms related to CHD and syndrome. We found a wide range of dysmorphisms (ocular region, ears, mouth, and/or palate and phalangeal anomalies) detected in more than half of MSGs were found to be associated with CHDs, but those anomalies are also described in genomic rearrangements syndromes with equal prevalence. These findings confirmed that etiological diagnosis in newborns is challenging, and only the prompt and expert recognition of features suggestive of genetic conditions can improve the selection of appropriate, cost-effective diagnostic tests. However, in general practice, it is crucial to recognize clues that can suggest the presence of a genetic syndrome, and neonatologists often have the unique opportunity to be the first to identify abnormalities in the neonate.

Neonates Born to COVID-19 Mother and Risk in Management within 4 Weeks of Life: A Single-Center Experience, Systematic Review, and Meta-Analysis.

OBJECTIVE: The new coronavirus infection from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been recognized as a global public health emergency, and neonates may be more vulnerable due to their immature immune system. The first aim of this study was to report our experience on the management of neonates from mothers with SARS-CoV-2 infection focusing on a 28-day follow-up since birth. The second aim is to assess how many data on neonatal outcomes of the first month of life are reported in literature, performing a systematic review and meta-analysis. STUDY DESIGN: We report our experience based on routine management of neonates born to mothers with SARS-CoV-2 infection and follow-up until 28 days of life. RESULTS: In our experience at discharge, 1/48 (2.08%) of entrusted (mother refusing personal protective equipment) and none of separated presented positive nasopharyngeal swab (p = NS). All babies show good outcome at 28 days of life. The literature data show that the percentage of positive separated infants is significantly higher than the percentage of infants entrusted to positive mothers with appropriate control measures (13.63 vs. 2.4%; p = 0.0017). Meta-analysis of studies focused on follow-up showed a 2.94% higher risk of incidence of SARS-CoV-2 infection in entrusted newborns than in separated newborns (95% confidence interval: 0.39-22.25), but this was not significant (p = 0.30). CONCLUSION: A vertical transmission in utero cannot be totally excluded. Since in newborns, the disease is often ambiguous with mild or absent symptoms, it is important to define the most efficient joint management for infants born to COVID-19 positive mothers, being aware that the risk of horizontal transmission from a positive mother, when protective measures are applied, does not seem to increase the risk of infection or to affect the development of newborns from birth to first four weeks of life, and encourages the benefits of breastfeeding and skin-to-skin practice. KEY POINTS: · Entrusting the newborn to the positive mother does not increase the risk of infection.. · Our follow-up shows that newborns have good growth and outcome at one month of life.. · Applying protective measures we suggest breastfeeding and skin-to-skin practice..

Neurodevelopmental outcomes of neonatal non-epileptic paroxysmal events: a prospective study.

AIM: To report on psychomotor development and outcomes in term born neonates with non-epileptic paroxysmal events (NEPEs). METHOD: From October 2017 to March 2019 we enrolled 38 consecutive term born neonates (22 males, 16 females; aged between 0-28d), born at the University Hospital San Marco in Catania, Italy, with NEPEs. We performed the Hammersmith Neonatal Neurological Examination scale (at enrolment), the Hammersmith Infant Neurological Examination (HINE) scale (at age 3, 6, 9, and 12mo), and the Griffiths scale (at age 12mo). RESULTS: The age at onset of first paroxysmal manifestations ranged from birth to 4 days. We recorded a suboptimal global score in 18 out of 38 patients at enrolment and in 10 out of 38 patients at age 3 months (>70% of these infants were male); all events disappeared within 6 months of life. At age 6, 9, and 12 months, all infants scored within normal values on the HINE and Griffiths scale. INTERPRETATION: Patients with NEPEs achieve neurodevelopment optimal scores within their first year of life. WHAT THIS PAPER ADDS: Neonates experiencing non-epileptic paroxysmal events (NEPEs) can be examined with the Hammersmith Neonatal Neurological Examination, Hammersmith Infant Neurological Examination, and Griffiths scale at follow-up. Newborn infants with NEPEs achieve optimal scores within the first year of life.

Diagnostic Clue in a Neonate with Amniotic Band Sequence.

Amniotic band syndrome (ABS) is a set of congenital malformations that mainly affect the limbs and more rarely the skull, face, chest, and abdomen. Two main hypotheses have been proposed to explain the nature of the disorder: an intrinsic and extrinsic factor. We report a newborn with ABS presenting with several malformations involving both hands and foot. In this case, the malformative event localized at the hands and right foot without involvement of any other internal organs and is asymmetric which leads us to suppose the extrinsic factor as cause of the ABS.

Prehypertension in adolescents with cardiovascular risk: a comparison between type 1 diabetic patients and overweight subjects.

BACKGROUND: Adolescents with type 1 diabetes and obesity present higher cardiovascular risk and ambulatory blood pressure measurements (ABPM) has been shown to predict vascular events, especially by identifying the nondipper status. The aim of our observational cross-sectional study conducted in adolescents with type 1 diabetes, overweight subjects and healthy controls was to assess mean blood pressure parameters to identify subclinical cardiovascular risk. METHODS: The study included adolescents patients with type 1 diabetes followed in our Pediatric Department in University of Catania between January 2011 and 2013. A total of 60 patients were enrolled, and 48 (32 male and 16 female) completed the study. For each subject we performed systolic and diastolic Ambulatory Blood Pressure Measurements (ABPM) during wakefulness and sleep recording blood pressure every 30 min for 24 h with the Tonoport V/2 GE CardioSoft V6.51 device. We compared the data of patients with those of overweight subjects and healthy controls. RESULTS: ABPM revealed no significant difference between type 1 diabetic patients and overweight subjects in 24 h Systolic, 24 h Diastolic, Day-time Systolic, Night-time systolic and Day-time Diastolic blood pressure values but significantly different values in Night-time Diastolic blood pressure values (p < 0.001). We found significant differences between type 1 diabetic patients and healthy controls in all 24 h Systolic (p < 0.001), 24 h Diastolic (p < 0.01), Day-time Systolic (p < 0.01), Night-time Systolic (p < 0.001), Day-time Diastolic (p < 0.05) and Night-time Diastolic (p < 0.001) blood pressure values. We detected hypertension in 12/48 (25%) type 1 diabetic patients and in 10/48 overweight subjects (p = 0.62; OR 1.2; CI 0.48-3.29), whereas no-one of healthy controls presented hypertension (p < 0.001). We observed nondipper pattern in 40/48 (83.3%) type 1 diabetic patients, in 33/48 (68.8%) overweight subjects (p = 0.094; OR 2.27; CI 0.85-6.01), and in 16/48 (33.3%) of healthy controls (p < 0.001; OR 10; CI 3.79-26.3). CONCLUSIONS: ABPM studies might help to define a subset of patients at increased risk for the development of hypertension. In evaluating blood pressure in type 1 diabetes and overweight subjects, ABPM should be used since a reduced dipping can indicate incipient hypertension.

Sputum high mobility group box-1 in asthmatic children: a noninvasive sensitive biomarker reflecting disease status.

BACKGROUND: The monitoring of asthma is based mainly on clinical history, physical examination, and lung function test evaluation. To improve knowledge of the disease, new biomarkers of airway inflammation, including high mobility group box-1 (HMGB1), are being developed. OBJECTIVE: To evaluate sputum HMGB1 levels in children with stable, off-therapy, allergic asthma and to evaluate the relation between HMGB1 levels and lung function parameters. METHODS: Fifty children with asthma (28 boys and 22 girls, median age 11.56 ± 1.41 years) and 44 healthy children (22 boys and 22 girls, median age 11.07 ± 2.12 years) were enrolled. Sputum HMGB1 was assessed in the cohort study. Lung function (predicted percentage of forced expiratory volume in 1 second [FEV1%] and forced expiratory flow between 25% and 75% [FEF25%-75%]), serum total IgE levels, and asthma severity by validated Global Initiative for Asthma criteria were recorded. RESULTS: Sputum HMGB1 levels were higher in children with asthma than in healthy controls (100.68 ± 10.03 vs 9.60 ± 3.76 ng/mL, P < .0001). Sputum HMGB1 levels also were positively related to total IgE levels in children with asthma (r = 0.6567, P < .0001). An inverse and strict correlation between sputum HMGB1 levels and pulmonary function indices also were observed in children with mild (FEV1%, r = -0.86544, P < .0001; FEF25%-75%, r = -0.53948, P < .05), moderate (FEV1%, r = -0.99548, P < .0001; FEF25%-75%, r = -0.48668, P < .05), and severe (FEV1%, r = -0.90191, P < .0001; FEF25%-75%, r = -0.66777, P < .05) asthma. CONCLUSION: The present study provides evidence that sputum HMGB1 is a sensitive biomarker of allergic asthma in children because it was increased and correlated directly with asthma severity and inversely with lung function indices.

Heart involvement in children and adults with cystic fibrosis: correlation with pulmonary indexes and inflammation markers.

BACKGROUND: Cardiovascular involvement in Cystic Fibrosis (CF) is a not rare condition, although the prevalence of subclinical pulmonary hypertension (PH) and cardiac dysfunction is not known in the early stages of CF progression. The aim of our study was to assess cardiac involvement in children and adults affected by cystic fibrosis compared with healthy subjects of same age using echocardiography. METHODS: Fifty-five patients, 25 adults and 30 children completed the study. We assessed FEV1 (Forced Expiratory Volume in one second), and carried out colour Doppler-echocardiography evaluating ejection fraction (EF) measurement of left ventricle, tricuspid annular plane systolic excursion (TAPSE) of right ventricle and pulmonary artery pressure (PAP). We compared the auxological, respiratory and cardiologic data with those of 16 adults and 34 children of the same age. RESULTS: We discovered significantly different values of PAP between patients and controls in both children (p = 0.0001, r=- 0.62) and adults (p=0.0001, r=- 0.63), whereas the EF and TAPSE showed significantly different values in only adults (p=0.0023 and p=0.0194 respectively). We found in both children and adults with CF an inverse correlation between PAP and FEV1 (p=0.000, p=0.001), Erythrocyte Sedimentation Rate (ESR) and FEV 1 (p=0.015, r=- 0.43; p=0.009, r=- 0.51), and highly sensitive C-reactive protein (hs-CRP) and FEV 1 (p=0.007, r=- 0.48; p=0.001, r=- 0.60). In adults we also detected direct correlation between PAP and hs-CRP (p=0.008, r=0.51) and PAP and ESR (p=0.009, r=0.51). CONCLUSIONS: In paediatric-aged CF patients there are already early signs of potential heart impairment, represented by an increase of pulmonary blood pressure, and in adult age the systolic function of right ventricle may be impaired. We hypothesise that such cardiac impairments may gradually arise due to preceding chronic inflammation related to prior degeneration of lung function and thus it is very important to keep patients clinically stable and address chronic inflammation as early as possible in the progression of CF.

Effects of Sustained Lung Inflation, a lung recruitment maneuver in primary acute respiratory distress syndrome, in respiratory and cerebral outcomes in preterm infants.

BACKGROUND: Sustained Lung Inflation (SLI) is a maneuver of lung recruitment in preterm newborns at birth that can facilitate the achieving of larger inflation volumes, leading to the clearance of lung fluid and formation of functional residual capacity (FRC). AIM: To investigate if Sustained Lung Inflation (SLI) reduces the need of invasive procedures and iatrogenic risks. STUDY DESIGN: 78 newborns (gestational age≤34 weeks, weighing≤2000 g) who didn't breathe adequately at birth and needed to receive SLI in addition to other resuscitation maneuvers (2010 guidelines). SUBJECTS: 78 preterm infants born one after the other in our department of Neonatology of Catania University from 2010 to 2012. OUTCOME MEASURES: The need of intubation and surfactant, the ventilation required, radiological signs, the incidence of intraventricular hemorrhage (IVH), periventricular leukomalacia, retinopathy in prematurity from III to IV plus grades, bronchopulmonary dysplasia, patent ductus arteriosus, pneumothorax and necrotizing enterocolitis. RESULTS: In the SLI group infants needed less intubation in the delivery room (6% vs 21%; p<0.01), less invasive mechanical ventilation (14% vs 55%; p≤0.001) and shorter duration of ventilation (9.1 days vs 13.8 days; p≤0.001). There wasn't any difference for nasal continuous positive airway pressure (82% vs 77%; p=0.43); but there was less surfactant administration (54% vs 85%; p≤0.001) and more infants received INSURE (40% vs 29%; p=0.17). We didn't found any differences in the outcomes, except for more mild intraventricular hemorrhage in the SLI group (23% vs 14%; p=0.15; OR=1.83). CONCLUSION: SLI is easier to perform even with a single operator, it reduces the necessity of more complicated maneuvers and surfactant without statistically evident adverse effects.

Assessment of coronary artery intimal thickening in patients with a previous diagnosis of Kawasaki disease by using high resolution transthoracic echocardiography: our experience.

BACKGROUND: Kawasaki disease (KD) is a generalized systemic vasculitis of unknown etiology involving medium and small size blood vessels, particularly the coronary arteries. In these vessels a progressive stenosis may result from active remodeling with an intimal proliferation and neoangiogenesis. The aim of our study was to assess, by using high-resolution transthoracic 2D Echocardiography, if subjects with a previous diagnosis of Kawasaki disease after several years show a coronary intimal thickening, suggestive of a persistent cardiovascular risk. METHODS: We assessed measurement of thickening, inner diameter and outer diameter of coronary arteries using 2D Echocardiography (Philips E 33 with multy-frequency S8-3 and S12-4 probes) and examining the proximal portion of left main coronary artery just above the aortic valve with parasternal short axis view. RESULTS: We found a significant intimal thickening in patients with previous Kawasaki disease compared to healthy controls. In particular, we noticed that also subjects not suffering from coronary impairment in acute phase have higher values of thickening than healthy controls, and this wall thickening may confer a higher cardiovascular risk. CONCLUSIONS: Therefore we concluded that the assessment of coronary artery thickening by high-resolution transthoracic 2D Echocardiography may become an essential instrument to evaluate late cardiovascular risk in subjects with a diagnosis of Kawasaki disease in childhood.

Rhabdomyomas and tuberous sclerosis complex: our experience in 33 cases.

BACKGROUND: Rhabdomyomas are the most common type of cardiac tumors in children. Anatomically, they can be considered as hamartomas. They are usually randomly diagnosed antenatally or postnatally sometimes presenting in the neonatal period with haemodynamic compromise or severe arrhythmias although most neonatal cases remain asymptomatic. Typically rhabdomyomas are multiple lesions and usually regress spontaneously but are often associated with tuberous sclerosis complex (TSC), an autosomal dominant multisystem disorder caused by mutations in either of the two genes, TSC1 or TSC2. Diagnosis of tuberous sclerosis is usually made on clinical grounds and eventually confirmed by a genetic test by searching for TSC genes mutations. METHODS: We report our experience on 33 cases affected with rhabdomyomas and diagnosed from January 1989 to December 2012, focusing on the cardiac outcome and on association with the signs of tuberous sclerosis complex. We performed echocardiography using initially a Philips Sonos 2500 with a 7,5/5 probe and in the last 4 years a Philips IE33 with a S12-4 probe. We investigated the family history, brain, skin, kidney and retinal lesions, development of seizures, and neuropsychiatric disorders. RESULTS: At diagnosis we detected 205 masses, mostly localized in interventricular septum, right ventricle and left ventricle. Only in 4 babies (12%) the presence of a mass caused a significant obstruction. A baby, with an enormous septal rhabdomyoma associated to multiple rhabdomyomas in both right and left ventricular walls died just after birth due to severe heart failure. During follow-up we observed a reduction of rhabdomyomas in terms of both number and size in all 32 surviving patients except in one child. Eight patients (24,2%) had an arrhythmia and in 2 of these cases rhabdomyomas led to Wolf-Parkinson-White Syndrome. For all patients the arrhythmia spontaneously totally disappeared or was reduced gradually. With regarding to association with tuberous sclerosis, we diagnosed tuberous sclerosis clinically in 31 babies (93,9%). CONCLUSION: Rhabdobyomas are tumors with favorable prognosis because they frequently do not cause symptoms and they often regress in numbers and size. Nevertheless, due to frequent association with tuberous sclerosis complex and the resulting neurological impairment, the prognosis can result unfavorable.
