RESUMEN
AIM: The study assessed the relationship between vitamin D status in infants and the presence of allergic and/or respiratory disorders. MATERIALS AND METHODS: The study cohort comprised 81 hospitalized infants presenting at the Pediatric Clinic, University Clinical Center Kragujevac, Serbia, between January 2011 and June 2016. RESULTS: The age of the infants ranged from 29 days to 12 months. All infants received prophylactic doses of vitamin D3 of 400 IU/daily until the end of the first year of life regardless of whether they are fed with adapted infant formula (n = 20) or breast milk (n = 37) or concurrently both (n = 24), up to the 5th month of life. The mean level of plasma 25(OH)D was 29.65 ng/mL. Hypovitaminosis D (mean serum level of 25(OH)D < 30 ng/mL) was found in n = 38 infants of which 6 presented with severe vitamin D deficiency (level below 10 ng/mL), 13 presented with vitamin D deficiency (level between 10 and 20 ng/mL) and 19 had vitamin D insufficiency (levels between 20 and 30 ng/mL). The median vitamin D serum level in infants with allergic disease (n = 16) was 32.35 ng/mL and in infants with respiratory disease (n = 65) 28.99 ng/mL. CONCLUSION: Daily vitamin D3 supplementation with 400 IU in infants until the end of the first year of life is too low to provide optimal defense against respiratory and/or allergic conditions.

In children, the incidence of Legionnaires' disease (LD) is unknown, hospital-acquired LD is associated with clinical risk factors and environmental risk, and children with cell-mediated immune deficiency are at high risk of infection. Both newborns were born in the same delivery room; stayed in the same hospital room where they were cared for, bathed, and breastfed; were male; were born on time, with normal birth weight, and with high Apgar score at birth; and survived this severe infection (L. pneumophila, serogroup 2-15) but with different clinical courses. In neonate 1, bleeding in the brain, thrombosis of deep pelvic veins, and necrosis of the lungs, which left behind cystic and cavernous changes in the lungs, were found, while neonate 2 suffered from pneumonia alone. The only difference in risk factors for LD between these two newborns is the number of days of illness until the start of azithromycin treatment (sixth versus the third day of illness). We suggest that a change in the guidelines for diagnosing and treating community-acquired pneumonia and hospital-acquired pneumonia in newborns is needed in terms of mandatory routine testing for Legionella pneumophila. Early initiation of macrolide therapy is crucial for the outcome of LD in the newborn.

Background and Objectives: Although vitamin D insufficiency or deficiency is prevalent in children with allergic diseases, recommendations for supplementation dosing regimens are imprecise and variable in the literature, because clinical trials aiming to determine optimal doses were scarce in the past. This study aimed to investigate supplementation of vitamin D3 that may achieve therapeutically effective but not toxic serum levels in a subpopulation of children with allergic diseases and concomitant hypovitaminosis D. Materials and Methods: The retrospective, observational study with a cross-sectional design included 94 children suffering from allergic diseases and having vitamin D deficiency/insufficiency who were prescribed high-dose vitamin D3 supplementation by a pediatrician for at least 6 weeks and not more than 9 weeks. Serum levels of the major metabolite of vitamin D (25-(OH)D) were determined in all children twice: before and two weeks after the end of vitamin D3 supplementation. Results: An increase in serum level of the 25-(OH)D after supplementation was significant. However, if the subjects had higher serum levels of the 25-(OH)D before the supplementation, and if the supplementation lasted 8 instead of 6 weeks, the absolute increase in serum level of the 25-(OH)D was lower. Patients taking corticosteroids as inhalation or intranasally had a more intense effect of vitamin D3 supplementation, i.e., the absolute increase in levels of 25-(OH)D was higher than in patients not using such medication. Conclusions: Vitamin D deficiency and insufficiency in children with allergic diseases can be treated with maximal recommended doses of vitamin D3 for a short period of time, especially if they were prescribed with inhalation or intranasal corticosteroids.

BACKGROUND: Atopic dermatitis is a major public health issue worldwide, but data on trends in prevalence in children in European countries are sparse. The aim of this study was to assess the trends in the prevalence of atopic dermatitis in children under 5 in the Central, Eastern, and Western European sub-regions from 1990 to 2019. METHODS: In this study, a descriptive, observational epidemiological method was applied. In addition, an ecological study design was used. Joinpoint regression analysis was used to assess trends. RESULTS: A total of 118 million (54 million males and 64 million females) prevalent cases of atopic dermatitis in children under 5 were reported in European countries in 1990-2019. More than half of all cases of atopic dermatitis in children under 5 in Europe were recorded in the Western European sub-region. The highest prevalence rates of atopic dermatitis in children under 5 were observed in the Eastern European sub-region, with the highest rates in both males and females recorded in Estonia (equally at about 15,000 per 100,000), followed by the Russian Federation (equally at about 12,000 per 100,000). Moreover, the lowest prevalence rates were reported in the Eastern European sub-region (equally at about 5000 per 100,000 in Romania and Latvia). A sex disparity in the prevalence and trends of atopic dermatitis in children under 5 was observed. A significantly increased trend in atopic dermatitis prevalence in children under 5 was recorded in the Eastern European sub-region from 1990 to 2019 (by +0.3% per year in males and by +0.1% per year in females). Conversely, in the Western and Central European sub-regions, trends in the prevalence of atopic dermatitis in children under 5 slightly decreased (about -0.1% per year). The Pearson coefficient showed a significant negative correlation between the prevalence of atopic dermatitis in children under 5 and the Human Development Index in most countries in the Eastern European sub-region, while a significant positive correlation was reported between the prevalence and HDI in high-income countries in the Western European sub-region. CONCLUSIONS: High prevalence rates and mostly stable trends during the last three decades make atopic dermatitis still a major health issue in children under 5 in European countries.
RESUMEN
When hypostatic pneumonia is present at the same time as COVID-19 pneumonia, the clinical course is almost always prolonged (prolonged-COVID-19) due to persistent inflammation, long-term anti-inflammatory syndrome, followed by immune exhaustion, i.e., by immunosuppression and catabolic syndrome. In the immunosuppression phase, viral reactivation can be accompanied by a secondary infection, which, in this case, is pulmonary tuberculosis. Pulmonary tuberculosis in post-COVID-19 patients and in patients with spastic quadriplegic cerebral palsy does not have a typical clinical course nor laboratory, radiological, immunological, microbiological, or fiberbronchoscopic pathohistological confirmation. Due to this, the treatment of pulmonary tuberculosis was not carried out on time, postponed after the unsuccessful treatment of sepsis, post-COVID-19, and other accompanying viral (adenovirus, RSV) and bacterial (streptococcus viridans) infections. The treatment of pulmonary tuberculosis was possible only "ex juvantibus" (trial) post-COVID-19. It becomes imperative to search for a new, more precise and reliable diagnostic test for the detection of tuberculosis bacillus.
RESUMEN
Legionnaires' disease is an atypical pneumonia caused by inhaling small droplets of water containing the bacterium Legionella spp. In newborns, it is a rare event, usually associated with water births and the use of air conditioning systems or air humidifiers. A nosocomial outbreak of Legionnaires' disease in the maternity ward of a secondary-care hospital in Arandjelovac, Serbia is described.Two male newborns were found to be infected with Legionnella pneumophila. On Days 7 and 6 of life, respectively, they were transferred to a tertiary-care hospital with signs of severe pneumonia which was radiologically confirmed. L. pneumophila was detected in tracheal secretions from both infants by RT-PCR, and its antigens were also positive in urine samples. The source of infection in the secondary-care hospital was the internal hot water heating system, and the main contributory factor to the emergence of the infection was the low temperature of the hot water which did not kill the bacteria during the available exposure time.These two cases highlight the importance of being cautious about possible Legionnaires' disease in maternity wards with outdated or irregularly maintained internal water supply systems. The adoption of official guidelines for the control and regular maintenance of water supply systems, including the multidisciplinary cooperation of all relevant parties, forms the basis for direct monitoring for Legionella and the prevention of new outbreaks.Abbreviations: BCYE: buffered charcoal yeast extract agar; GVPC: glycine vancomycin polymyxin cycloheximide agar; LD - Legionnaires' disease; TR-PCR: Reverse transcription polymerase chain reaction.

This study aimed to provide additional information on the influence of perinatal factors on fecal (f)-calprotectin values in preterm infants. Calprotectin was determined from the first spontaneous stool (analyzed on the Alegria device by using the enzyme-linked immunosorbent assay [ELISA] method) obtained from neonates at a mean age of 3.41 ± 2.44 days of life. We analyzed 114 subjects who had a body weight of 1847.67 ± 418.6 g and were born at a gestational age of 32.6 ± 2.43 weeks, without intestinal and other congenital anomalies or any diseases other than those related to premature birth. The values of f-calprotectin are in a positive correlation with female subjects, intrauterine growth restriction, significant ductus arteriosus, enteral feeding intolerance, postnatal prolonged use of broad-spectrum antibiotics, and values ââof bicarbonates (analyzed in a sample of capillary arterial blood). Measurement of f-calprotectin in the first 7 days after birth can help to early detect the intestinal distress or early staging of necrotizing enterocolitis in premature infants.
RESUMEN
INTRODUCTION: Urban life is often followed by immune dysfunction and loss of immune tolerance in the youngest children. OBJECTIVE: The study aimed to determine optimal time efficiency of a synbiotic (5 x 109 Lactobacillus acidophilus Rosell-52, Bifidobacterium infantis Rosell-33, Bifidobacterium bifidum Rosell-71) in controlling respiratory infections and wheezing disease. METHODS: We randomly selected a group of children younger than five years, hospitalized earlier, and classified them into three groups. RESULTS: The incidence of respiratory infection before the study was once a month, while after a three-month supplementation with the synbiotic children rarely suffered from respiratory infections, and the state was maintained after six-month and nine-month supplementations with the synbiotic. The decreased incidence of respiratory infections was followed by a falling incidence of concomitant wheezing. A significant increase in tIgA serum was observed in all groups for only three months, the increase being the highest in children with recurrent respiratory infections accompanied by wheezing. After a nine-month administration of the synbiotic, total IgE serum was lower in all groups of patients. CONCLUSION: The optimal duration of administration of the synbiotic containing three probiotic cultures to provide effective control of the frequency of respiratory infections was three months, and six months were required to establish control of the frequency of wheezing. This synbiotic is useful for immunomodulation in children and is well-tolerated in young children.

Introduction: The consequences of autologous and allogeneic stem cell transplantation (stem cells of hematopoiesis), applied in adults and children suffering from leukemia or some other malignant disease, are well-known and sufficiently recognizable in pediatric clinical practice regardless of the indication for the treatment. However, the efficacy of fetal stem cell transplantation is unrecognizable when the indications are psychomotor retardation and epilepsy. Case Outline: With the exception of neurological psychiatric problems, a boy aged 9.5 years was in good general health before transplantation with allogeneic fetal stem cells. The main aim of allogeneic fetal stem cell transplantation was treatment of psychomotor retardation and epilepsy. After 13 months of treatment, he was admitted to hospital in a very serious, life-threatening condition due to sepsis and severe pleuropneumonia. The humoral immunity in the boy was adequate, unlike cellular immunity. The immune imbalance in terms of predominance of T-suppressor lymphocytes contributes to delayed and late development of sepsis and severe pleuropneumonia. The boy still shows the same severity of psychomotor retardation, dyslalia, epilepsy, strabismus and amblyopia. Conclusion: Implementation of fetal stem cell therapy for unconfirmed indications abuses the therapeutic approach, harms patients, misleads parents, and brings financial harm to the healthcare system of any country, including Serbia.

INTRODUCTION: Cystic fibrosis (CF) is a multisystemic autosomal recessive disease most frequently recognized by characteristic respiratory and/or digestive manifestations. Exceptionally rare, as is the case with the infant we are presenting, the initial sign of the disease can be nutritional deficiency dermatitis (NDD). CASE OUTLINE: A three-month-old male infant of young and healthy non-consanguineous parents, born at term after the first uneventful pregnancy, was hospitalized due to atopic dermatitis (AD)-like skin changes, failure to thrive and normochromic anemia (Hb 60 g/L). As exclusively breast-fed, failure to thrive was attributed to hypogalactia and skin changes to nutritional allergy, so that, besides exclusion of cow's milk protein and other highly allergenic foods in mother's diet, hypoallergenic milk formula was added to the child's diet. However, dietetic measures were without effect, and the child was re-hospitalized at age 4.5 months, this time in the condition of severe malnutrition with hypoproteinemic edemas, extensive dermatitis, moderate hepatosplenomegaly and recurrent normochromic anemia (Hb 57 g/L). After plasma-free erythrocyte transfusion, correction of hypoalbuminemia and two-week parenteral and semi-elementary nutrition resulted in gradual recovery of the child, also including the resolution of skin changes. Having in mind the clinical course of the disease, as well as the response to applied therapeutic measures, CF was suspected as the cause of the child's problems, which was also confirmed by a high level of sweat chlorine (92 mmol/L) and DNA analysis (deltaF508/deltaF508). CONCLUSION: Our experience indicates that NDD, as the initial manifestation of CF, should be also kept in mind in differential diagnosis of the infant's AD-like changes.

Subcutaneous fat necrosis of newborns is a transient, benign process in full- term or postmature neonates. It is associated with perinatal distress. Newborn stress inhibits immature enzyme system, which already has relative inability to desaturate saturated fatty acids. It leads to fat crystillisation and necrosis. Skin biopsy revealed necrotic focus and crystallisation in fat cells. Hypercalcemia may be a potential complication.
