Recognition of nuts and seeds in children with/without food allergies and their mothers: A reflection of culinary culture.

BACKGROUND: Nuts and seeds are among the leading causes of food allergy. Effective food allergy management hinges on the ability to identify and avoid relevant foods. AIM: To evaluate the nut/seed recognition ability in both children and mothers. METHODS: Primary caregivers (mothers) and their children (6-18 years old) with/without food allergies were shown photographs of nuts/seeds, and their products with visible/hidden allergens to assess their ability to recognize accurately. RESULTS: A total of 196 children and 184 mothers participated. The median ages of the children and mothers were 7.6 (6.8-10) and 37.8 (33.1-41.5) years, respectively. Over 75% of the children/adolescents and over 90% of the mothers accurately identified the kernel forms of nuts/seeds, except pine nuts. Walnuts, hazelnuts, almonds, and cashews were the most accurately recognized kernel forms by both populations. Generally, the kernel forms were recognized 5-20% more accurately than their in-shell forms, followed by products with visible and hidden forms, respectively. Some Turkish culinary-specific products with visible/hidden allergens were recognized as frequently as the kernel/in-shell forms by both study groups. Although there was a similar recognition pattern between study groups and subgroups (nut/seed allergy, other food allergy, controls), higher rates of recognition were found in mothers than in their children and adolescents than in schoolchildren. CONCLUSION: In Eastern Mediterranean region, nuts and sesame seeds are highly recognized by both mothers and their children. Accurate identification of these foods is likely a culinary feature, but not the result of increased awareness. More information is needed on whether this ability reduces the risk of exposure.

Clinical, genetic characteristics and treatment outcomes of children and adolescents with osteogenesis imperfecta: a two-center experience.

BACKGROUND: Osteogenesis imperfecta (OI), is a heritable, heterogeneous connective tissue disorder, characterized by fragile bones. There are conflicting results about genotype-phenotype correlations and efficiency of bisphosphonate treatment in this disorder. AIM: We aimed to evaluate the clinical, genetic characteristics, and long-term follow-up results of children and adolescents with OI. MATERIALS AND METHODS: A two-center retrospective study was conducted using demographic, clinical, and genetic data obtained from the medical records of the patients. RESULTS: Twenty-nine patients (62% male, median age; 3.6 years) with OI diagnosis from 26 families were included in the study. Thirteen different variants (nine were novel) were described in 16 patients in COL1A1, COL1A2, and P3H1 genes. Our siblings with homozygous P3H1 variants had a severe phenotype with intrauterine and neonatal fractures. Twenty-two patients were treated with bisphosphonates (17 of them with pamidronate, five with alendronate) with a median duration of 3.0 (1.6-4.8) years. Eleven patients (50%) suffered from fractures after the treatment. Haploinsufficiency variants in COL1A1 caused a milder skeletal phenotype with less fracture count and better treatment outcomes than structural variants. When compared with the anthropometric measurements at the initial diagnosis time, height Z-scores were lower on the last clinical follow-up (p = 0.009). CONCLUSIONS: We could not find an obvious genotype-phenotype correlation in Turkish OI patients with COL1A1 or COL1A2 variants. Treatment with pamidronate was effective in reducing fracture counts, without any long-term adverse effects.

Cutaneous manifestations of obesity in Turkish children: A comparative study.

BACKGROUND: Cutaneous changes in obese adults have been investigated in numerous studies, but this issue has not been adequately investigated in children. OBJECTIVES: We aimed to determine the prevalence of skin manifestations in children with obesity by comparing them to normal-weight children. METHODS: A cross-sectional study was conducted between June 2017 and January 2019 in which 82 children with obesity and 86 normal-weight healthy control children were enrolled. Study participants had detailed full-body skin examinations performed by the same dermatologist; mycological and Wood's lamp examinations were performed when necessary. Sociodemographic and anthropometric measurements of the participants were recorded. RESULTS: Striae distensae were the most common skin manifestation in children with obesity; striae were significantly higher in the obese than in the control group (72% vs. 26.7%, p < .001). The anatomical distribution of the striae distensae in the groups differed significantly. Striae distensae were most commonly observed on the buttocks in the control group, while the thighs were the most common site in the obese group. Acanthosis nigricans (63.4% vs. 3.5%, p < .001), acrochordons (17.1% vs. 1.2%, p < .001), keratosis pilaris (32.9% vs. 17.4%, p = .021), intertrigo (11% vs. 0%, p = .001), folliculitis (31.7% vs. 5.8%, p < .001), seborrheic dermatitis (12.2% vs. 3.5%, p = .035) and facial erythema (7.3% vs. 0%, p = .012) were found to be statistically significantly more common in the obese group compared to the control group. CONCLUSIONS: Obesity in children is associated with numerous cutaneous manifestations. Further study is needed to identify whether weight loss can reduce skin manifestations in obese children.

The treatment journey of children with moderate to severe atopic dermatitis in Türkiye: unmet needs.

BACKGROUND: Atopic dermatitis (AD) substantially burdens individuals, families, and healthcare systems. We aimed to document the treatment journey of pediatric patients with moderate-to-severe AD in a referral center based in our country. METHODS: This retrospective study reviewed patients aged 1-18 years diagnosed with AD, seeking systemic treatment recommendations from the "pediatric allergy and dermatology multidisciplinary team meeting". RESULTS: Over the 14-month study period, 30 (12.5%) of 240 AD patients were evaluated in the pediatric dermato-allergy team meetings. The median age of the patients was 13.66 years (Q1-Q3: 7.94-17.27), of whom 60% were male. The median annual healthcare visits for AD were 4 (Q1-Q3: 1.00-8.75). Among the study group, 70% were sensitized to aeroallergens, and admission markers included total IgE (median: 1980 IU/mL, Q1-Q3: 794.50-5446), and eosinophil counts (median: 650, Q1-Q3: 275-1275). All patients utilized intermittent and/or continuous topical corticosteroids (CS), with 56.6% employing short-term/long-term topical tacrolimus. Over the past two years, systemic CSs were utilized in 93.3% of the patients, whereas 57.1% received more than one course. Approximately 43.3% of the patients agreed to receive systemic cyclosporine treatment, with only 30.8% benefiting and 3.3% reporting adverse effects (hypertrichosis and cellulitis). Three patients self-funded dupilumab, all benefiting without adverse effects. Omalizumab, mycophenolate mofetil and narrow-band  ultraviolet (UV) treatments were used in one patient each, with limited benefit observed. Health insurance did not grant approval for a Janus kinase inhibitor for one patient. CONCLUSIONS: Managing moderate to severe AD is complex and costly, considering disease heterogeneity, comorbidities, care pathways, and health system challenges. Addressing the unmet needs should be a priority in Türkiye's healthcare systems.

The many faces of pediatric urticaria.

Urticaria is a common disease that can affect individuals of all age groups, with approximately one-quarter of the population experiencing it at least once in their lifetime. Lesions characterized by erythema and itchy hives can appear anywhere on the body. These can vary in size ranging from millimeters to centimeters, and typically clear within 24 h. About 40% of patients with urticaria have accompanying angioedema, which involves localized deep tissue swelling. Urticaria usually occurs spontaneously and is classified into acute and chronic forms, with the latter referring to a condition that lasts for more than 6 weeks. The prevalence of chronic urticaria in the general population ranges from 0.5% to 5%, and it can either be inducible or spontaneous. The most common form of pediatric urticaria is acute and is usually self-limiting. However, a broad differential diagnosis should be considered in children with urticaria, particularly if they also have accompanying systemic complaints. Differential diagnoses of pediatric urticaria include chronic spontaneous urticaria, chronic inducible urticaria, serum sickness-like reaction, urticarial vasculitis, and mast cell disorders. Conditions that can mimic urticaria, including but not limited to cryopyrinopathies, hyper IgD syndrome, Periodic Fever, Aphthous Stomatitis, Pharyngitis and Adenitis (PFAPA), Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPs), and Schnitzler syndrome should also be considered. The many faces of pediatric urticaria can be both easy and confusing. A pragmatic approach relies on clinical foresight and understanding the various forms of urticaria and their potential mimickers. This approach can pave the way for an accurate and optimized diagnostic approach in children with urticaria.
