Minipuberty period of children with atopic dermatitis compared to healthy children.

Background/aim: Atopic dermatitis (AD) is an inflammatory, pruritic, noncontagious, chronic relapsing skin disease. Skin barrier abnormalities, excessive T helper 2 activity, and immune dysregulation are held responsible. Androgens have a negative effect on the integrity of the epidermal skin barrier, while estrogen has a positive effect.

Expanding the clinical and immunological phenotypes of PAX1-deficient SCID and CID patients.

Paired box 1 (PAX1) deficiency has been reported in a small number of patients diagnosed with otofaciocervical syndrome type 2 (OFCS2). We described six new patients who demonstrated variable clinical penetrance. Reduced transcriptional activity of pathogenic variants confirmed partial or complete PAX1 deficiency.

Factors that predict disease severity in atopic dermatitis: The role of serum basal tryptase.

Background: Increased numbers of mast cells that contain tryptase are found in lesional atopic dermatitis (AD) skin. The association of serum basal tryptase (sBT) with anaphylactic reactions and mast cell diseases has recently been shown in children with venom and food allergy.

Objective: We aimed to identify the risk factors that predict the severity of AD and the association of sBT levels with AD and disease severity.

CLINICAL FEATURES AND GENETIC ANALYSIS OF SIX PATIENTS WITH WISKOTT-ALDRICH SYNDROME REPORTING TWO NOVEL MUTATIONS: EXPERIENCE OF ERCIYES UNIVERSITY, KAYSERI, TURKEY.

Aim: The Wiskott-Aldrich syndrome (WAS) is an X-linked immunodeficiency characterized by micro-thrombocytopenia, eczema, and recurrent infections. We aimed to share our experience with six children with WAS, including two patients with two novel mutations.

Material And Method: We present phenotypical and laboratory description of six patients with WAS.

Increased Postexercise Lipoxin A4 Levels in Exhaled Breath Condensate in Asthmatic Children With Exercise-Induced Bronchoconstriction.

Background: Lipoxins could be potential modulators of inflammation in the lungs. To our knowledge, the role of exhaled breath condensate (EBC) lipoxin A4 (LXA4) in asthmatic children with exercise-induced bronchoconstriction (EIB) has not been investigated.

Objective: The aim of our study was to determine the involvement of EBC LXA4 in EIB.

The association of forced expiratory volume in one second and forced expiratory flow at 50% of the vital capacity, peak expiratory flow parameters, and blood eosinophil counts in exercise-induced bronchospasm in children with mild asthma.

Background: Exercise-induced bronchoconstriction (EIB), which describes acute airway narrowing that occurs as a result of exercise, is associated with eosinophilic airway inflammation, bronchial hyperresponsiveness. The forced expiratory volume in one second (FEV1) is the most commonly used spirometric test in the diagnosis of EIB in exercise challenge in asthma. Other parameters such as forced expiratory flow at 50% of the vital capacity (FEF50%) and peak expiratory flow (PEF) are used less often in the diagnosis of EIB.

An evaluation of serum paraoxonase together with arylesterase activities and oxidative stress in children with intractable epilepsy: a cross-sectional study.

Epilepsy is the most common chronic neurological illness in childhood and adolescence. The aim of this study was to investigate paraoxonase and arylesterase activities along with oxidative status parameters in children with intractable epilepsy. The study comprised 42 subjects with intractable epilepsy and a control group of 35 healthy subjects.

Hypomorphic homozygous mutations in phosphoglucomutase 3 (PGM3) impair immunity and increase serum IgE levels.

Background: Recurrent bacterial and fungal infections, eczema, and increased serum IgE levels characterize patients with the hyper-IgE syndrome (HIES). Known genetic causes for HIES are mutations in signal transducer and activator of transcription 3 (STAT3) and dedicator of cytokinesis 8 (DOCK8), which are involved in signal transduction pathways. However, glycosylation defects have not been described in patients with HIES.

The clinical features and genetic mutations of chronic granulomatous disease: results from a reference centre at middle Anatolia.

Aim: Chronic granulomatous disease (CGD) is a rare innate immune deficiency with neutrophil function disorder. In this retrospective study, we aimed to evaluate the clinical features of the patients with CGD.

Material And Method: We presented eight patients (6 boys, 2 girls) with CGD which were evaluated at Erciyes University Medical Faculty hospital between 1996 and 2012.

Severe congenital neutropenia in two siblings related to HAX1 mutation without neurodevelopmental disorders.

Severe congenital neutropenia (SCN) is a rare primary myelopoiesis disorder, characterized by reduced absolute neutrophil counts from birth, increased susceptibility to recurrent and life-threatening infections, and a preleukemic predisposition. Herein, we describe two siblings with SCN born from consanguineous parents who were referred for complaints of recurrent cutaneous infections, gingivitis, purulent otitis media, and both lower and upper respiratory tract infections. Bone marrow aspiration of one patient demonstrated a maturation arrest in the myeloid lineage at the promyelocyte-myelocyte stages.

Anaphylaxis Provoked by Bovine Gelatin Caused by Ingestion of Jelly Candy and Using Hair Gel.

Gelatin, a product obtained by the partial hydrolysis of collagen, is widely used in foods and pharmaceuticals. In the past, most commercially available vaccines, both live and inactivated, contained gelatin as a stabilizer, and allergic reactions to gelatin contained in measles, mumps, and rubella vaccine were reported. However, gelatin-allergy to foods was thought to be rare.

Autoimmune diseases detected in children with primary immunodeficiency diseases: results from a reference centre at middle anatolia.

Primary immunodeficiency diseases (PIDs) are a heterogeneous group of disorders that genetically affect distinct components of the immune system; thus, predispose individuals to recurrent infections, allergy, autoimmunity, and malignancies. In this retrospective study, autoimmune diseases (ADs), which developed during the course of PID in children, were discussed.Twenty-five patients were included in this study.

Hashimoto thyroiditis associated with ataxia telangiectasia.

Ataxia telangiectasia is a rare genetic disease characterized by neurological manifestations, infections, and cancers. In addition to these cardinal features, different autoimmune diseases can be seen in patients with ataxia telangiectasia. Although there were reports of positive autoimmune thyroid antibodies associated with ataxia telangiectasia, to our knowledge, we report the first cases of nodular Hashimoto thyroiditis in two patients with ataxia telangiectasia in the English medical literature.

A mutation of aspartoacylase gene in a Turkish patient with Canavan disease.

Canavan disease (CD) is an autosomal recessive inherited disorder characterized by spongy degeneration of the brain. The deficiency of aspartoacylase (ASPA), resulting in the accumulation of N-acetyl aspartic acid (NAA) in the brain, plays an important role in the pathogenesis of the disease. The cardinal features of this neurodegenerative disease are macrocephaly, mental retardation, and hypotonia.
