Second-generation immigrant children: health prevention for a new population in terms of vaccination coverage and health assessment.

BACKGROUND: In recent years the total number of foreigners taking up residence in Italy is increasing: the number of children born in Italy to foreign parents currently account for 15% of all babies born in the country. This population is generally referred to as "second-generation immigrants". We evaluated the health conditions of this particular population by investigating the vaccination coverage and auxological data in a group of foreign children living in a foster care setting and by comparing them to those regarding a group of foreign children living with their own parents. METHODS: This study was conducted in a foster care association in Rome. The Pediatric Unit of "A. Gemelli" Hospital, Rome, provided all data for comparison. Two groups of children (group 1: 60 children from a foster care association; group 2: 91 children living with their parents; group 3: 112 healthy controls) with similar characteristics were taken into consideration. RESULTS: There were statistical differences between groups: the administration rate of hexavalent vaccine was significantly higher in group 2 than in group 1 (84.6% vs. 65.0%) (P<0.01); the administration rate of measles, mumps and rubella vaccine, again, was significantly higher in group 2 compared to group 1 (69.0% vs. 47.5%) (P<0.05); the administration rate of heptavalent pneumococcal vaccine, however, was higher in group 1 (21/60; 35.0%) than in group 2 (20/91; 21.9%) (P>0.05), although the administration rate of serogroup C meningococcal vaccine was lower in group 1 (10/60; 16.7%) compared to group 2 (17/91; 18.7%) (P>0.05). As for auxological parameters, there were no statistical differences between groups. CONCLUSIONS: The data presented in this study seem to suggest the need for a special health programme to be promoted by the Italian National Health System in order to address the needs of the particular risk group of second-generation immigrant children. Vaccination coverage should be especially boosted, and pediatricians should have a key role in terms of awareness raising and education of immigrant families.

A twenty-year retrospective study of pediatric tuberculosis in two tertiary hospitals in Rome.

BACKGROUND: Tuberculosis (TB) is among the top 10 causes of child death worldwide. Nevertheless, childhood disease has been neglected by tuberculosis control programs. METHODS: This was a retrospective study of patients < 16 years of age diagnosed with active TB in 2 tertiary hospitals in Rome (Italy), between 1990 and 2009. RESULTS: Two hundred fourteen cases of active tuberculosis were identified (132 definite, 82 probable). Pulmonary involvement was the most common form (75.5%), followed by lymphadenopathy (15.4%) and central nervous system TB (11%). Fever (51.86%) and cough (40%) were the most common presenting symptoms. A total of 23.4% of children were asymptomatic on admission. Sensitivities of the tuberculin skin test and the quantiferon test were 93.4% and 97%, respectively. Both tests performed in 52 children agreed in 49 cases (94%). Sensitivities for culture, Ziehl-Neelsen staining and polymerase chain reaction were 58%, 25% and 66.3%, respectively. The adult source case was identified in 28% of cases. History of contact with a patient with active TB was associated with pulmonary TB (P = 0.0014), whereas negative history of contact was associated with lymph node (P = 0.0064) and central nervous system TB (P = 0.05). CONCLUSIONS: Our study emphasizes the difficulty in managing children with suspected TB, because the absence of constitutional symptoms cannot exclude TB, and bacteriologic confirmation is the exception. Immunologic diagnosis can be a valuable tool to identify TB-infected children because the quantiferon test showed high sensitivity in all age groups. This is of primary importance because early identification of children with latent tuberculous infection and appropriate chemoprophylaxis represent, to date, the most important tool to reduce the burden of TB.

Maternal and neonatal characteristics of an immigrant population in an Italian hospital.

OBJECTIVE: The objective of this study was to evaluate clinical and epidemiological characteristics of the maternal and neonatal immigrant population and to compare it with the Italian population in the Agostino Gemelli Hospital (Rome). METHODS: This study was a prospective population-based study. We compared 595 newborns from immigrant mothers with 2413 newborns from Italian mothers. Neonatal characteristics included in this study were sex, gestational age, birth weight, Apgar score, transfer to pathology units, minor pathologies, and type of breastfeeding at discharge. Maternal characteristics included nationality, age, parity, type of delivery, twin birth, and pathology during the pregnancy. RESULTS: Immigrant newborns comprised 20% of the total births included in the study. No statistically significant differences were found between immigrant and Italian newborns in gestational age, birth weight, or Apgar score. Immigrant newborns were transferred to the Paediatric Infectious Disease Unit more frequently than Italian newborns, had a significantly higher incidence of hyperbilirubinemia and a higher rate of exclusive and prevalent breastfeeding at discharge. Immigrant mothers came predominantly from Eastern Europe, were younger and had caesarean sections less frequently than Italian mothers. CONCLUSION: No significant differences in biological and clinical characteristics or in medical practice were found between groups, except for a higher frequency of neonatal hyperbilirubinemia and an inclination among immigrant mothers toward breastfeeding.

An uncommon presentation for a severe invasive infection due to methicillin-resistant Staphylococcus aureus clone USA300 in Italy: a case report.

BACKGROUND: Methicillin resistant Staphylococcus aureus (MRSA) has been considered for many years a typical nosocomial pathogen. Recently MRSA has emerged as a frequent cause of infections in the community. More commonly, community-acquired (CA)-MRSA is a cause of infections of the skin and soft-tissues, but life-threatening infections such as necrotizing pneumonia and sepsis can occasionally occur. CASE PRESENTATION: This report describes an uncommon presentation of invasive CA-MRSA infection in an adolescent without known risk factors. The presentation was typical for bacterial meningitis, but the clinical findings also revealed necrotizing pneumonia. Following the development of deep venous thrombosis, the presence of an inherited thrombophilic defect (factor V Leiden) was detected. The patient was successfully treated with an antibiotic combination including linezolid and with anticoagulant therapy. CA-MRSA was isolated from both cerebrospinal fluid and blood. The isolates were resistant to oxacillin and other beta-lactam antibiotics and susceptible to the other antibiotics tested including erythromycin. Molecular typing revealed that the strains contained the Panton-Valentine leukocidin genes and type IV SCCmec, and were ST8, spa type t008, and agr type 1. This genetic background is identical to that of the USA300 clone. CONCLUSION: This report highlights that meningitis can be a new serious presentation of CA-MRSA infection. CA-MRSA strains with the genetic background of the USA300 clone are circulating in Italy and are able to cause severe infections.

Candida albicans endocarditis diagnosed by PCR-based molecular assay in a critically ill pediatric patient.

A young Down's syndrome patient developed tricuspid valve endocarditis several years after undergoing surgical closure of a congenital ventricular septal defect. Fungal etiology was established by PCR amplification of the Candida albicans ERG11 gene. Although antifungal therapy was administered, surgical replacement of the infected valve was required to eliminate the infection.
