Assessment and management of asthma exacerbations in an emergency department unit.

BACKGROUND: The Pediatric Respiratory Assessment Measure (PRAM) score is a useful tool for the assessment of asthma exacerbations in children. This study aimed to estimate the risk of hospitalization in children, assessed with the PRAM score and having mild-moderate asthma exacerbation, who were treated with salbutamol delivered via a metered-dose inhaler and spacer (MDI/S). METHODS: The study population consisted of children aged 3-16 years with mild-moderate asthma exacerbations. All children received 1mg/kg prednisolone p.o. (max 40 mg) and 4-6 puffs of salbutamol via MDI/S. RESULTS: Fifty patients participated in the study. Admission was associated positively with the initial PRAM score (OR: 18.91, CI: 2.42-123.12, P = 0.005) and negatively with the improvement in PRAM score (OR: 0.52, CI: 0.01-0.78, P = 0.032). CONCLUSION: PRAM is a reliable tool that can be used effectively to estimate the asthma exacerbation severity.

Angiotensin-converting-enzyme insertion/deletion polymorphism, ACE activity, and COVID-19: A rather controversial hypothesis. A case-control study.

Accumulating data has shown a contribution of the renin-angiotensin system in COVID-19 pathogenesis. The role of angiotensin-converting enzyme (ACE) insertion (I)/deletion (D) polymorphism as a risk factor in developing COVID-19 disease comes from epidemiological data and is controversially discussed. We conducted a retrospective case-control study and assessed the impact of ACE I/D genotype in COVID-19 disease prevalence and severity. In 81 COVID-19 patients explicitly characterized and 316 controls, recruited during the first wave of COVID-19 pandemic, ACE I/D genotype, and ACE activity were determined. A generalized linear model was used and Poisson regression analysis estimated the risk ratios (RRs) of alleles and genotypes for disease severity. DD patients had almost 2.0-fold increased risk (RR: 1.886, confidence limit [CL] 95%: 1.266-2.810, p = 0.0018) of developing a more severe disease when contrasted to ID and II individuals, as did D allele carriers compared to I carriers (RR: 1.372; CL 95%: 1.051-1.791; p = 0.0201). ACE activity (expressed as arbitrary units, AU/L) was lower in patients (3.62 ± 0.26) than in controls (4.65 ± 0.13) (p < 0.0001), and this reduction was observed mainly among DD patients compared to DD controls (3.97 ± 0.29 vs. 5.38 ± 0.21; p = 0.0014). Our results demonstrate that ACE DD genotype may predispose to COVID-19 increased disease severity via a mechanism associated, at least in part, with the significant fall in their ACE activity. Our findings suggest a more complex pattern of synergy between this polymorphism and ACE activity in COVID-19 patients compared to healthy individuals and set the grounds for large-scale studies assessing ACE genotype-based optimized therapies with ACE inhibitors and angiotensin receptor blockers.

The role of respiratory syncytial virus- and rhinovirus-induced bronchiolitis in recurrent wheeze and asthma-A systematic review and meta-analysis.

INTRODUCTION: Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis. RSV-induced bronchiolitis has been associated with preschool wheeze and asthma in cohort studies where the comparison groups consist of healthy infants. However, recent studies identify rhinovirus (RV)-induced bronchiolitis as a potentially stronger risk factor for recurrent wheeze and asthma. AIM: This systematic review and meta-analysis aimed to compare the associations of RSV- and RV-induced bronchiolitis with the development of preschool wheeze and childhood asthma. METHODS: We performed a systematic search of the published literature in five databases by using a MeSH term-based algorithm. Cohort studies that enrolled infants with bronchiolitis were included. The primary outcomes were recurrent wheeze and asthma diagnosis. Wald risk ratios and odds ratios (ORs) were estimated, along with their 95% confidence intervals (CIs). Individual and summary ORs were visualized with forest plots. RESULTS: There were 38 studies included in the meta-analysis. Meta-analysis of eight studies that had data on the association between infant bronchiolitis and recurrent wheeze showed that the RV-bronchiolitis group were more likely to develop recurrent wheeze than the RSV-bronchiolitis group (OR 4.11; 95% CI 2.24-7.56). Similarly, meta-analysis of the nine studies that had data on asthma development showed that the RV-bronchiolitis group were more likely to develop asthma (OR 2.72; 95% CI 1.48-4.99). CONCLUSION: This is the first meta-analysis that directly compares between-virus differences in the magnitude of virus-recurrent wheeze and virus-childhood asthma outcomes. RV-induced bronchiolitis was more strongly associated with the risk of developing wheeze and childhood asthma.

Takayasu arteritis in an adolescent with Crohn's disease.

Crohn's disease (CD) and Takayasu arteritis (TA) are two distinct clinical entities. Τhe likelihood of both diseases coexisting is low, and although CD co-occurs with all types of vasculitis, TA is the most common subtype. Herein, the case of a 15-year-old female, diagnosed with TA following an initial diagnosis of CD, is reported. A review of the literature, including a systemic review of the case reports and case series of children and adolescents up to the age of 21, with both CD and TA, follows the case description. In total, 28 cases of TA and CD were retrieved. The median age of patients was 14.8 years, they were mostly females (72%) and the median time between the two diagnoses was 3.7 years. In the majority of cases, CD was diagnosed first and TA followed. Computed tomography angiography and magnetic resonance angiography were the preferred imaging modalities to assist diagnosis.

Metabolic syndrome in Greek women with polycystic ovary syndrome: prevalence, characteristics and associations with body mass index. A prospective controlled study.

PURPOSE: The aim of this study was to estimate the prevalence, to evaluate the characteristics of the metabolic syndrome (MetS) in Greek women with polycystic ovary syndrome (PCOS) and to investigate the correlation of MetS with body mass index (BMI). METHODS: In a prospective controlled study, 230 Greek female patients with PCOS and 155 age-matched healthy controls were enrolled. Diagnosis of PCOS was based on the revised criteria of Rotterdam. Both groups were examined for MetS. Diagnosis of MetS was based on the revised criteria of International Diabetes Federation (IDF). RESULTS: The prevalence of the MetS was 12.6 %, nearly sevenfold higher than the controls. Elevated fasting plasma glucose (7.0 vs. 1.9 %) and elevated triglycerides (10.4 vs. 3.2 %) were more frequent in the PCOS cohort (p < 0.05). Women with PCOS presented statistically higher BMI in comparison with the controls (p < 0.001). Subsequently, the prevalence of MetS was estimated in three groups: normal, overweight and obese subdivided according to BMI. The latter two groups showed significant differences compared with the healthy controls (24.5 vs. 8.8 %, p = 0.050). CONCLUSION: In conclusion, this study showed high prevalence of MetS and increased BMI in Greek PCOS women. In addition, it demonstrated the higher prevalence of MetS in obese PCOS women in comparison with the controls. These results are placing them at increased risk for cardiovascular disease and diabetes in the future and underline the necessity of periodic screening, appropriate diet and exercise program.

Human Placental LRP5 and Sclerostin are Increased in Gestational Diabetes Mellitus Pregnancies.

INTRODUCTION: The low-density lipoprotein receptor-related protein 5 (LRP5) and its inhibitor sclerostin, are key components of bone metabolism and potential contributors to type 2 diabetes mellitus susceptibility. This study aims at evaluating the expression of placental LRP5 and sclerostin in pregnancies with gestational diabetes mellitus (GDM) and investigate possible associations with umbilical sclerostin concentrations and clinical outcomes in mothers and their neonates. METHODS: Twenty-six GDM-mothers and 34 non-GDM mothers of Caucasian origin and their neonates admitted in a gynecology and obstetrics department of a university hospital were included in this study. Demographic data and maternal fasting glucose concentrations (24-28 weeks of gestation) were retrieved from the patients' medical records. Placental LRP5 was determined by immunohistochemistry (IHC) and Western blotting analysis; placental sclerostin was determined by IHC. Umbilical serum sclerostin concentrations were measured by ELISA. RESULTS: Placental sclerostin IHC intensity values were positively correlated with LRP5 values as detected either by IHC (r = 0.529; P < .001) or Western blotting (r = 0.398; P = .008), with pregestational maternal body mass index values (r = 0.299; P = .043) and with maternal fasting glucose concentrations (r = 0.475; P = .009). Placental sclerostin and LRP5 were significantly greater in GDM compared with non-GDM placentas (histo-score: 65.08 ± 17.09 vs 11.45 ± 2.33, P < .001; 145.53 ± 43.74 vs 202.88 ± 58.65, P < .001; respectively). DISCUSSION: Sclerostin and LRP5 were detected in human placentas. The overexpression of placental sclerostin and LRP5 values in GDM compared with non-GDM pregnancies, as well as the positive association of placental sclerostin values with pregestational maternal body mass index and maternal fasting glucose concentrations may indicate the development of an adaptive mechanism in face of maternal hyperglycemia.

A dedicated surveillance network for congenital toxoplasmosis in Greece, 2006-2009: assessment of the results.

BACKGROUND: Toxoplasmosis is caused by infection with the protozoan parasite Toxoplasma gondii. Acute infections in pregnant women may be transmitted to the fetus and cause severe illness. The purpose of this study was to establish a dedicated surveillance network (DSN) for congenital toxoplasmosis (CT) in Greece, in order to assess the birth prevalence of CT. METHODS: A DSN of thirty clinicians was established for reporting CT cases from hospitals throughout Greece. The clinicians were selected on the basis that there was a high possibility the suspected cases would be referred to them from district hospitals or private clinics. Suspected cases of CT were reported on a monthly basis with a zero reporting card during a surveillance period from April 2006 to December 2009. A questionnaire was sent for any suspected case to record information including demographic parameters, clinical signs and symptoms and laboratory results. Serological and molecular confirmation of cases was performed by the Pasteur Hellenic Institute. All newborns suspected of CT received treatment and were serologically and clinically followed up for one year. RESULTS: The monthly response rate reached 100%, although only after reminders sent to 65% of the participant physicians. Sixty-three suspected CT cases were recorded by the DSN during the study period including fourteen confirmed and seven probable cases. Ten cases (47.6%) presented with symptoms at birth. Chorioretinitis was the most prominent manifestation, occurring in five symptomatic CT cases (50%). No other symptoms appeared by the end of the one year clinical follow up. No case was recorded by the existing surveillance system of the Hellenic Center of Disease Control and Prevention (HCDCP) during the same time period. Birth prevalence was estimated at 0.45, 0.51 and 0.51 per 10,000 births for 2007, 2008 and 2009 respectively. The incidence rate of symptomatic CT at birth was estimated at 0.10 cases per 10,000 births per year in Greece (for the period 2007-2009). CONCLUSION: The DSN for CT proved to be more sensitive than the classical notification system, easy in application and very efficient in reporting rare diseases such as CT. Similar DSNs could be used to provide useful information on other rare diseases.

Erythromelalgia in an Adolescent Female.

Erythromelalgia is a disabling syndrome of paroxysmal vasodilation affecting the feet, hands and face characterised by patient's cooling behaviour to achieve symptom relief. It can be primary or secondary and although a rare disorder it has been described in children and adolescents. We describe the case of a 14-year-old female diagnosed with primary erythromelalgia successfully treated with aspirin, amitriptyline, and carbamazepine.

Cerebral venous sinus thrombosis in the setting of COVID-19 vaccination: a systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Cerebral venous sinus thrombosis (CVST) has been reported as a rare adverse event in association with thrombosis-thrombocytopenia syndrome (TTS) following COVID-19 vaccination. METHODS:  We performed a systematic review and meta-analysis of investigator-initiated registries including confirmed CVST cases, with the aim to calculate (1) the odds ratio of TTS-CVST versus non-TTS-CVST after vector-based vaccines and (2) after non-vector-based vaccines, (3) the in-hospital mortality ratio of TTS-CVST compared to non-TTS-CVST; and (4) the dependency or death at discharge among TTS-CVST compared to non-TTS-CVST cases. RESULTS: Two eligible studies were included in the meta-analysis, comprising a total of 211 patients with CVST associated with COVID-19 vaccination. Vector-based COVID-19 vaccination was associated with a higher likelihood of TTS-associated CVST than with non-TTS-CVST (OR: 52.34, 95% CI 9.58-285.98). TTS-CVST was also associated with higher likelihood of in-hospital mortality (OR: 13.29; 95% CI 3.96-44.60) and death or dependency at discharge compared to non-TTS-CVST (OR: 6.70; 95% CI 3.15-14.26). TTS-CVST was recorded with a shorter interval between vaccination and symptom onset [Mean Difference (MD):-6.54 days; 95% CI - 12.64 to - 0.45], affecting younger patients (MD:-9.00 years; 95% CI - 14.02 to - 3.99) without risk factors for thromboses (OR:2.34; 95% CI 1.26-4.33), and was complicated more frequently with intracerebral hemorrhage (OR:3.60; 95% CI 1.31-9.87) and concomitant thromboses in other sites (OR:11.85; 95% CI 3.51-39.98) compared to non-TTS-CVST cases. CONCLUSIONS: TTS-CVST following COVID-19 vaccination has distinct risk factor profile, clinical phenotype and prognosis compared to non-TTS-CVST. Further epidemiological data are required to evaluate the impact of different treatment strategies on outcome of TTS-CVST cases following COVID-19 vaccination.

Poor Adherence to the Screening-Based Strategy of Group B Streptococcus Despite Colonization of Pregnant Women in Greece.

Group B streptococcus (GBS) is a leading cause of serious neonatal infections. Maternal GBS colonization is associated with early- and late-onset neonatal disease (EOD/LOD). In Greece, a screening-based strategy is recommended, in which concurrent vaginal-rectal cultures should be obtained between 36 0/7 and 37 6/7 weeks' gestation. We sought to examine the level of adherence to the GBS screening guidelines and estimate the prevalence of GBS colonization among pregnant women. Although in Greece the screening-based strategy is followed, we also examined known EOD risk factors and linked them to GBS colonization. A cross-sectional study of 604 women postpartum in three hospitals and maternity clinics was conducted. Following written informed consent, data were collected via a short self-completed questionnaire and review of patients' records. In 34.6% of the enrolled pregnant women, no culture had been taken. Of the remaining, 12.8% had proper vaginal-rectal sample collections. The overall maternal colonization rate was 9.6%. At least one risk factor for EOD was identified in 12.6% of participants. The presence of risk factors was associated with positive cultures (p = 0.014). The rate of culture collection did not differ between women with or without an EOD risk factor. Adherence to a universal screening of pregnant women with vaginal-rectal cultures was poor. Despite probable underestimation of GBS carrier status, almost 1 in 10 participants were GBS positive during pregnancy. Screening of women with risk factors for EOD should, at least, be prioritized to achieve prevention and prompt intervention of EOD.

Cerebral Venous Sinus Thrombosis and Thrombotic Events After Vector-Based COVID-19 Vaccines: A Systematic Review and Meta-analysis.

BACKGROUND AND OBJECTIVES: There is accumulating evidence supporting an association between the thrombosis and thrombocytopenia syndrome (TTS) and adenovirus vector-based vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Yet TTS and TTS-associated cerebral venous sinus thrombosis (CVST) remain poorly characterized. We aim to systematically evaluate the proportion of CVST among TTS cases and assess its characteristics and outcomes. METHODS: We performed a systematic review and meta-analysis of clinical trials, cohorts, case series, and registry-based studies with the aim to assess (1) the pooled mortality rate of CVST, TTS-associated CVST, and TTS and (2) the pooled proportion of patients with CVST among patients with any thrombotic event and TTS. Secondary outcomes comprised clinical characteristics of patients with postvaccination thrombotic event. This meta-analysis is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was written according to the Meta-analysis of Observational Studies in Epidemiology proposal. RESULTS: Sixty-nine studies were included in the qualitative analysis comprising 370 patients with CVST out of 4,182 patients with any thrombotic event associated with SARS-CoV-2 vector-based vaccine administration. Twenty-three studies were included further in quantitative meta-analysis. Among TTS cases, the pooled proportion of CVST was 51% (95% confidence interval [CI] 36%-66%; I 2 = 61%). TTS was independently associated with a higher likelihood of CVST when compared to patients without TTS with thrombotic events after vaccination (odds ratio 13.8; 95% CI 2.0-97.3; I 2 = 78%). The pooled mortality rates of TTS and TTS-associated CVST were 28% (95% CI 21%-36%) and 38% (95% CI 27%-49%), respectively. Thrombotic complications developed within 2 weeks of exposure to vector-based SARS-CoV-2 vaccines (mean interval 10 days; 95% CI 8-12) and affected predominantly women (69%; 95% CI 60%-77%) under age 45, even in the absence of prothrombotic risk factors. DISCUSSION: Approximately half of patients with TTS present with CVST; almost one-third of patients with TTS do not survive. Further research is required to identify independent predictors of TTS following adenovirus vector-based vaccination. REGISTRATION INFORMATION: The prespecified study protocol has been registered in the International Prospective Register of Ongoing Systematic Reviews PROSPERO (CRD42021250709).

Children and Adolescents With SARS-CoV-2 Infection: Epidemiology, Clinical Course and Viral Loads.

BACKGROUND: There is limited information on severe acute respiratory syndrome virus 2 (SARS-CoV-2) infection in children. METHODS: We retrieved data from the national database on SARS-CoV-2 infections. We studied in-family transmission. The level of viral load was categorized as high, moderate, or low based on the cycle threshold values. RESULTS: We studied 203 SARS-CoV-2-infected children (median age: 11 years; range: 6 days to 18.4 years); 111 (54.7%) had an asymptomatic infection. Among the 92 children (45.3%) with coronavirus disease 2019 (COVID-19), 24 (26.1%) were hospitalized. Infants <1 year were more likely to develop COVID-19 (19.5% of all COVID-19 cases) (P-value = 0.001). There was no significant difference between viral load and age, sex, underlying condition, fever and hospitalization, as well as between type of SARS-CoV-2 infection and age, sex, underlying condition and viral load. Transmission from a household member accounted for 132 of 178 (74.2%) children for whom the source of infection was identified. An adult member with COVID-19 was the first case in 125 (66.8%) family clusters. Child-to-adult transmission was found in one occasion only. CONCLUSIONS: SARS-CoV-2 infection is mainly asymptomatic or mild during childhood. Adults appear to play a key role in spread of the virus in families. Most children have moderate or high viral loads regardless of age, symptoms or severity of infection. Further studies are needed to elucidate the role of children in the ongoing pandemic and particularly in light of schools reopening and the need to prioritize groups for vaccination, when COVID-19 vaccines will be available.

Hepatotoxicity in an Adolescent with Black Iced Tea Overconsumption.

Tea is the most widely consumed beverage after water in the world. The consumption of iced tea has increased in Western countries and spiked among teenagers for enjoyment, freshening up and alertness. A teenager presented with symptoms of hepatitis. Liver ultrasound revealed sludge in the gallbladder. Laboratory investigations excluded all known causes of hepatotoxicity. Detail nutritional history revealed that the patient had been drinking 1.5-2 liters of black iced tea per day for the last three months. He was immediately advised to stop drinking any tea. Gradually all symptoms disappeared and two months after discontinuation of the tea, all liver enzymes returned to normal and the sludge in the gallbladder disappeared. This case report underlines the importance of a meticulous assessment of a child's dietary behavior when investigating a case of hepatotoxicity and raises awareness about the potential side effects of tea overconsumption.

Hypovitaminosis D in Healthy Pregnant Women and their Newborns in Greece.

BACKGROUND/OBJECTIVES: The aim of this work was to evaluate the current vitamin D status in healthy pregnant women and their newborns living in Greece and assess possible associations between 25(OH)D and anthropometric features of their fetuses and newborns. MATERIALS & METHODS: 81 healthy women were monitored during pregnancy. Biochemical markers related to bone metabolism, 25(OH)D and PTH levels were measured in serum samples of mothernewborn pairs at 1st trimester of pregnancy and at delivery in mothers, in cord blood and at the 3rd day of life of newborns. RESULTS: Maternal 25(OH)D levels at the 1st trimester of pregnancy (22.6±9.2ng/ml) were significantly higher than those at delivery (19.2±9.2ng/ml) (p<0.001). Furthermore, umbilical 25(OH)D levels (21.3±9.3ng/ml) were higher than maternal at delivery (p=0.005) and neonatal levels (19.4±10.4 ng/ml) (p=0.021). Only 57.3% of the mothers at the first trimester and 46.7% at delivery as well as 55.8% of the fetuses and 38.5% of the neonates had adequate vitamin D levels (25(OH)D≥30ng/ml). A significant positive correlation was found between fetal femur length at the 22nd week of gestation and maternal 25(ΟΗ)D at the 1st trimester of pregnancy (r=0.36, p=0.048) while body length was significantly higher in newborns whose mothers had sufficient 25(OH)D levels (51.5±2.1cm) compared with those whose mothers had insufficient or deficient 25(OH)D levels at delivery (50.6±2.0cm) (p=0.047). CONCLUSION: The study confirms inadequate levels of vitamin D in pregnant women in Greece associated with inadequate vitamin D levels of their fetuses and newborns.

Adherence to pneumococcal conjugate vaccination schedule and uptake rate as compared to the established diphtheria-tetanus-acellular pertussis vaccination in Cyprus.

BACKGROUND: Pneumococcus is a common cause of invasive and non-invasive infections in children. In areas with high vaccination coverage, universal infant vaccination with conjugated pneumococcal vaccine (PCV) has significantly decreased the incidence of vaccine type nasopharyngeal carriage and invasive pneumococcal disease. The aim of this study is to examine immunization coverage rate and timely administration of the recently introduced PCV and compare to the established diphtheria-tetanus-acellular pertussis vaccine (DTaP) with similar schedule. METHODS: A stratified random sample of healthy infants and children 6-36 months of age were recruited. Demographic data were collected from parents. Among enrolled children, immunization status for DTaP and PCV was noted from the child's health booklet. RESULTS: Of 1105 children enrolled in the study, 586 (53%) were vaccinated in the private sector and the rest in the public sector. A significant higher proportion of children vaccinated at the private sector were fully vaccinated for PCV (71% versus 58%, p < 0.05) while no difference in the DTaP coverage was observed. Conversely, the compliance to the recommended vaccination schedule was much higher in the public sector for the first and second dose of PCV and second dose of DTaP. The overall, timely administration was higher for the DTaP vaccine when compared to PCV (p < 0.05). Moreover, adherence to the program was higher for the firstborn child of the family while significant differences were observed between different geographic regions. Interestingly, co-administration of DTaP and PCV was observed in only 2% of the children. CONCLUSION: In children residing in Cyprus, vaccination coverage and adherence to PCV vaccination schedule are significantly lower compared to the established DTaP vaccine. There is an urgent need for increasing the overall vaccination coverage as well as improving the adherence to vaccination schedule. Possible interventions are proposed.

Childhood Visceral Leishmaniasis: Distinctive Features and Diagnosis of a Re-emerging Disease. An 11-year Experience From a Tertiary Referral Center in Athens, Greece.

BACKGROUND: Visceral leishmaniasis (VL) remains a public health issue in Greece. The aim of this study was to describe the clinical and epidemiologic characteristics of pediatric VL in our region as well as to evaluate the laboratory findings and the diagnostic techniques that are applied. METHODS: We retrospectively reviewed the medical records of all children diagnosed with VL in an 11-year period at a tertiary public hospital in the region of Athens. Demographic features, clinical information and laboratory findings were accessed. RESULTS: A total of 43 cases were recorded during 2005-2015. Median age of the patients was 3.7 years. Pallor (100%), fever (98%), hepatosplenomegaly (55.8%) and appetite loss (32.6%) were the most common presentations of the disease. The predominant laboratory abnormalities were anemia (100%), thrombocytopenia (90.7%), elevated inflammatory markers (86.1%) and decreased albumin/globulin (A/G) ratio (72.1%). Four patients developed secondary hemophagocytic lymphohistiocytosis syndrome, whereas in 3 others abdominal ultrasound showed splenic nodules. Bone marrow aspiration detected Leishmania parasites in 92.7% of cases and the rapid rK39 strip test indicated anti-Leishmania antibodies in 97.1% of children. In addition, all patients in whom indirect immunofluorescent antibody test was implemented had positive results. CONCLUSIONS: VL still affects children in our area. Fever, splenomegaly, anemia and appetite loss are the typical findings in children. Noninvasive techniques (immunofluorescent antibody test, rK39) in combination with bone marrow microscopy are useful in the diagnosis of pediatric VL.

OC35 - Child Friendly Healthcare Initiative, implementation project in a paediatric department in Greece.

UNLABELLED: Theme: Accreditation and quality improvement. INTRODUCTION: Child Friendly Healthcare Initiative (CFHI) aims to improve quality of experience and health care given to children and families by improving realisation of children's rights and reducing unnecessary fear, anxiety and suffering during and because of health care. AIM: To present results of preliminary CFH assessment. METHODS: Implementation was initiated in a paediatric department of a University Hospital in Athens, Greece, consisting of a 37-bed ward, Outpatient Clinic and Emergency Department. For the preliminary assessment of the CFHI tool No1, which is for parents-caregiverschildren and health workers, this was translated into Greek. 112 parents-caregivers and six children were interviewed by an independent interviewer. In total, 24 health workers - 5 paediatricians, 11 residents and 8 nurses - responded to the CFHI tool No 1. RESULTS: Issues highlighted were mostly about CFH Standard 3 and Standard 7. Suggestions for improvement in all Standards were suggested. CONCLUSIONS: Preliminary assessment revealed the quality of care needs improvement. The next step is the training health workers, planning and making improvements.

Nasopharyngeal Pneumococcal Carriage among Healthy Children in Cyprus Post Widespread Simultaneous Implementation of PCV10 and PCV13 Vaccines.

The objective of the study was to describe the incidence of pneumococcal nasopharyngeal carriage, serotype distribution and antibiotic resistance profile of pneumococcal nasopharyngeal isolates in healthy children aged 6 to 36 months following the implementation of conjugate vaccines. A nasopharyngeal swab was collected from 1105 healthy children following a stratified random sampling between September 2013 and April 2014. Demographics, vaccination status and data on possible risk factors were recorded. Isolates were serotyped and tested for antibiotic susceptibility. The nasopharyngeal carriage rate was 25.3%. Among 1105 children enrolled, 393 had received PCV13 and 685 PCV10. The prevailing isolated serotypes were: 23A (14.3%), 15A (8.9%), 6C (8.6%), 23B (7.5%), 19A (5.4%) and 15B (5%). The proportion of non-vaccine serotypes, PCV10 serotypes, PCV13 additional serotypes (3, 6A, 19A) was 76.8%, 2.1% and 10.4% respectively. Although children, who were fully or partially vaccinated with PCV13, were 63% less likely to be colonized with additional PCV13 serotypes compared to those vaccinated with PCV10, the difference is not significant (95%Cl = 0.14-1.02, p = 0.053). The highest antibiotic non-susceptible rates were found for erythromycin (28.2%) and penicillin (27.9%). The overall multidrug resistance rate was 13.2%, with serotypes 24F (4/6), 15A (14/25) and 19A (6/15) being the main contributors. Carriage rate was similar between children vaccinated with PCV10 or PCV13. The high incidence of 15A serotype which is also multidrug resistant should be underlined. Ongoing surveillance is needed to monitor the dynamics on nasopharyngeal carriage.

Enteral L-arginine supplementation for prevention of necrotizing enterocolitis in very low birth weight neonates: a double-blind randomized pilot study of efficacy and safety.

BACKGROUND: Necrotizing enterocolitis (NEC) is the most common acquired gastrointestinal disease in premature infants and has high mortality and morbidity. Endothelial nitric oxide is an important regulator of vascular perfusion and is synthetized from the amino acid L-arginine. Hypoargininemia is frequently observed in preterm neonates and may predispose them to NEC. Our objective was to determine the effect of enteral L-arginine supplementation on the incidence and severity of NEC in very low birth weight (VLBW) neonates. MATERIALS AND METHODS: We conducted a parallel blind randomized pilot study, comprising VLBW neonates with birth weight ≤1500 g and gestational age ≤34 weeks. VLBW neonates were randomly assigned to receive enteral L-arginine supplementation (1.5 mmol/kg/d bid) between the 3rd and 28th day of life or placebo. Diagnosis and classification of NEC were done according to modified Bell's criteria. RESULTS: Eighty-three neonates were randomized to the arginine (n = 40) or placebo (n = 43) group. No adverse effects were observed in neonates receiving L-arginine supplementation. The incidence of NEC stage III was significantly lower in the arginine-supplemented group (2.5% vs 18.6%, P = .030). CONCLUSIONS: Enteral L-arginine supplementation of 1.5 mmol/kg/d bid can be safely administered in VLBW neonates from the 3rd to the 28th day of life. Enteral L-arginine supplementation appears to reduce the incidence of stage III NEC in VLBW infants. Larger studies are needed to further evaluate the effect of L-arginine supplementation in preventing NEC in VLBW infants.
