Long-term safety and efficacy of topical cyclosporine in 156 children with vernal keratoconjunctivitis.

Vernal keratoconjunctivitis (VKC) is a chronic and potentially sight-threatening disease. Topical corticosteroids (Cs) seem to be the only effective treatment for this condition, although severe side effects may occur owing to their prolonged use. More recently, cyclosporine (Cyc) eye drops have been reported as a valid alternative, but so far such treatment has only been successfully experimented for a short time and in small numbers of patients.

Defective FOXP3 expression in patients with acute Kawasaki disease and restoration by intravenous immunoglobulin therapy.

Objectives: The aims of this study were: 1) to investigate forkhead box P3 (FOXP3) expression in patients with Kawasaki disease (KD), exploring possible differences during the acute phase and after defervescence; 2) to evaluate a possible association of the FOXP3 single nucleotide polymorphism (SNP) 543 (SNP ID: rs2232367) with KD.

Methods: FOXP3 expression was evaluated on 8 children with KD and 15 healthy children by flow cytometry and Real-Time polymerase chain reaction (RT-PCR). FOXP3 SNP 543 was genotyped by denaturing high-performance liquid chromatography (DHPLC) and sequencing on DNA samples from 58 additional children with KD and 114 healthy donors.

Macrophage migration inhibitory factor -173 polymorphism and risk of coronary alterations in children with Kawasaki disease.

Objective: To investigate the possible relationship between MIF -173 polymorphism and susceptibility to, and severity of, Kawasaki disease (KD) in a cohort of Italian patients.

Methods: Sixty-nine patients (43 F, 26 M, median age 29 months, range 3-135 months) with KD and 60 sex-matched healthy caucasian children were genotyped for MIF-173. Typing of the MIF gene -173 G/C was performed by PCR and restriction fragment length polymorphism.

Incidence and clinical significance of reactive thrombocytosis in children aged 1 to 24 months, hospitalized for community-acquired infections.

The aims of this study were to identify demographic, clinical and laboratory characteristics associated with reactive thrombocytosis useful for clinical management and to evaluate potential complications of this condition in a cohort of children selected for they young age as at high risk of reactive thrombocytosis. Retrospective analysis of medical records of 239 children among 902 aged 1-24 months, hospitalized during a 12-month period, and discharged with a diagnosis of infectious disease was performed. One hundred and nineteen children out of 239 (49.

Molecular detection methods and serotyping performed directly on clinical samples improve diagnostic sensitivity and reveal increased incidence of invasive disease by Streptococcus pneumoniae in Italian children.

The aims of this study were to evaluate the incidence of invasive pneumococcal disease (IPD) in Italian children and perform serotyping by PCR-based assays directly on clinical samples. A 1-year paediatric (0-14 years) population-based surveillance study was designed to evaluate the incidence of IPD in the province of Florence, Italy, by cultural and molecular methods. Among 92 children (80 with pneumonia, 8 with meningitis/sepsis, 4 with arthritis), 4 cases of IPD were diagnosed both by culture and real-time PCR and 18 cases exclusively by molecular methods.

Allergen specific nasal challenge to latex in children with latex allergy: clinical and immunological evaluation.

There are no data concerning the significance of allergen specific nasal challenge to latex (ASNCL) in the pediatric population and the effect of mometasone furoate nasal spray (MFNS), topic corticosteroid exerting a potent anti-inflammatory activity in children with latex allergic rhinitis. The aims of this study are: to investigate the clinical and immune pathological effects of ASNCL in children with latex allergy; to study the effects of MFNS pre-medication on the clinical and immune pathological effects of ASNCL in children with latex allergy. Thirteen children: 6 male and 7 female, mean (SD) age 9.

Vertical hepatitis C virus transmission is not related to mother-child class-1 HLA concordance.

Mother-child human leukocyte antigen (HLA)diversity is protective for vertical transmission of some viruses. The aim of this study is to evaluate the role of mother-child HLA diversity on hepatitis C virus (HCV) vertical transmission. Forty consecutive HCV infected and 46 consecutive control uninfected children born to HCV-RNA positive mothers were evaluated for HLA class-1 type concordance with their mothers.

Cost of varicella-related hospitalisations in an Italian paediatric hospital: comparison with possible vaccination expenses.

Objective: The aims of the study were to evaluate the economic burden of hospitalisations due to varicella in an Italian paediatric hospital during a 1-year period and to compare the data with potential expenses projected for a varicella mass vaccination programme.

Research Design And Methods: An observational, retrospective, cohort study was designed to measure hospital admission costs in a cohort of paediatric patients with varicella in a 12-month period. A cost comparison with a vaccination programme planned to prevent varicella in a whole birth cohort was performed.

Eyelash length in children with vernal keratoconjunctivitis: effect of treatment with cyclosporine eye drops.

The upper eyelashes in vernal keratoconjunctivitis (VKC) patients have been reported to be longer than in healthy age- and gender-matched subjects. Eyelash length positively correlated to the severity of the disease and negatively to the employment of cyclosporine eye drops, suggesting that specific humoral factors could be involved in both ocular inflammation and elongation of the eyelashes. The aim of the present study is to evaluate a possible relationship between eyelash length and the duration of topical cyclosporine treatment.

Diagnostic value of three different latex extracts.

The diagnosis of latex allergy is made on clinical history, but a confirmatory skin prick test (SPT) or a serological assay based on a commercial latex extract is always recommendable. Different raw materials can be used in the preparation of commercial latex extracts. Such extracts can consequently show both different qualitative profiles and a different diagnostic potential.

Sublingual immunotherapy with a latex extract in paediatric patients: a double-blind, placebo-controlled study.

Background: Natural rubber latex (NRL) allergy remains an important allergic disease triggering urticaria, asthma, angioedema and anaphylaxis. Specific immunotherapy can help to solve problems related to NRL allergy. So far, no controlled clinical trials have been performed in children suffering from NRL allergy.

Long eyelashes in a case series of 93 children with vernal keratoconjunctivitis.

Objective: Vernal keratoconjunctivitis (VKC) is a chronic conjunctivitis that affects children mainly in temperate areas, with exacerbations in spring and summer. Eyelashes provide natural protection for the eyes from sunshine, wind, and foreign bodies. These factors induce a worsening of signs and symptoms in VKC, whereas mechanical protection of the eyes produces relief.

Atopy and serum eosinophil cationic protein in 110 white children with vernal keratoconjunctivitis: differences between tarsal and limbal forms.

Background: A predominance of Th2 response has been suggested in vernal keratoconjunctivitis (VKC), and a high prevalence of IgE-sensitized (IgE-S) patients has been reported (positive skin prick test or serum-specific-IgE). Palpebral and bulbar VKC are considered to be expressions of the same disease and only occasional racial and histopathological differences are described between the two forms. Tear levels of eosinophil cationic proteins have been correlated with the severity of ocular symptoms; however, there is no published study that demonstrates the presence of serum markers of disease activity.
