Molecular analysis of cutaneous yeast isolates in the mycobiota of children with atopic dermatitis.

The skin of patients with atopic dermatitis (AD) has a greater diversity of mycobiota. An observational, prospective, cross-sectional, analytical, and comparative study was conducted involving 80 patients with AD Group (ADG) and 50 individuals without AD (wADG) in a tertiary hospital in Brazil. Skin scale samples were collected from the frontal, cervical, fossae cubital, and popliteal regions and identified using molecular biology techniques. The results showed that 47.5% of ADG had identified yeasts compared to 0% of wADG (P < .001). The yeasts Rhodotorula mucilaginosa and Candida parapsilosis were the most abundant. The probability of colonization increased with age, showing values of 40% at 60 months and 80% at 220 months (P = .09). The cervical region (12.5%) was colonized to the greatest extent. Our findings revealed that positive mycology was not more probable when the scoring of atopic dermatitis or eczema area and severity index value increased (P = .23 and .53, respectively). The results showed that the sex, age, and different population types directly affected the composition of the mycobiota in the population analyzed. A higher frequency of colonization and greater diversity of yeast species were detected in the cutaneous mycobiota of children with AD.

Atopic dermatitis (AD) is a skin disease that can be colonized by microorganisms. We evaluated patients with and without the disease and found a higher frequency of colonization by Rhodotorula mucilaginosa and Candida parapsilosis on the skin of children with AD.

Blau syndrome-the skin as a warning sign.

Blau syndrome is an autosomal dominant chronic inflammatory disease, which may begin with skin manifestations in the first months of life, alerting physicians to the diagnosis. This case reports a patient diagnosed jointly by pediatric dermatology and rheumatology consultants at two years of age.

Vitamin D supplementation and severity of atopic dermatitis: pre-post assessment.

BACKGROUND/OBJECTIVES: There is evidence that vitamin D (VD) supplementation may help in the management of atopic dermatitis (AD). The aim of this study was to assess the influence of VD supplementation on the severity of AD. METHODS: Pre-post interventional study with prospective data collection in patients younger than 14 years. The severity of AD was determined through SCORAD (SCORing Atopic Dermatitis) and classified as mild (SCORAD < 25), moderate (≥25 and <50), and severe (≥50). Skin prick test was performed in all patients. Serum VD levels were classified as sufficient (≥30 ng/mL), insufficient (29 to 21 ng/mL), and deficient (≤20 ng/mL); and those with inadequate levels received oral supplementation of VD for 3 months, and were reassessed after treatment. RESULTS: A total of 152 patients were included. Patients with sufficient vitamin levels had lower SCORAD values (p = 0.04). Further, 116 patients (76.3%) received VD supplementation and after 3 months, VD levels were significantly higher (35.9 ng/mL) compared to baseline levels (23.7 ng/mL, p < 0.001). At the same time, a reduction in the SCORAD index was observed (19.4 before vs 12.3 after supplementation, p < 0.001). Considering other factors that could influence the decrease in AD severity after VD supplementation, female gender was associated with a worse treatment response (p = 0.02). CONCLUSION: Vitamin D supplementation could be an adjuvant in reducing the severity of atopic dermatitis.

Mental disorders and atopic dermatitis in children and adolescents.

INTRODUCTION: Some authors point to a relationship between mental disorders (MD) and atopic dermatitis (AD), but few determine which MD these are, and none of them evaluate the impact of AD on their healthy siblings. AIM: To determine which MD affect children and adolescents with AD and compare it with the risk of their healthy siblings. MATERIAL AND METHODS: This is a cross-sectional, prospective study with the application of a risk assessment instrument for Mental Disorders in paediatric patients with AD and their siblings from September 2016 to June 2018. The evaluation instrument used to assess the risk of MD was the Child Behaviour Checklist (CBCL). The Wilcoxon-Mann-Whitney, Pearson's χ2 test with Yates correction and Fisher's exact test were used, considering a significance level of 5%. RESULTS: The risk of MD in participants with AD was 63.0%, and in the healthy siblings, 36.0% (p < 0.01). The risk was higher in participants with AD when compared to their siblings for the syndromes "Sleep Problems", "Thought Problems" and "Somatic Complaints". Parental concerns on socialization/bullying were also more frequent for participants with AD when compared to siblings. CONCLUSIONS: Children and adolescents with AD present a high risk of MD, and their healthy siblings also present impairment in their mental health. In both cases, this impairment is higher than the one expected in the Brazilian general paediatric population (24.6%) and global paediatric population (22.4%).

Colorimetric analysis of images in the follow-up of infantile hemangiomas.

BACKGROUND/OBJECTIVES: Infantile hemangiomas (IH) are common vascular tumors that appear early in life, have a rapid proliferative phase and slowly involute. There are no standardized ways to evaluate the regression of these lesions. We propose a colorimetric analysis of photographs to allow a more precise determination of IH treatment response and involution. METHODS: Patients 1-10 months of age with superficial or mixed IH were included. The lesions were managed with 0.5% topical timolol ophthalmic solution. Patients were followed for 16 weeks with 6 evaluations each. Photographic images were taken with a red and green circle placed beside each hemangioma. The photographs were treated as to equalize the size, color, and brightness among them based on the colors of the two circles. A grading scale was established based on the color of the patient skin (0) and the color of the hemangioma at the beginning of treatment (100) by pixel analysis using Adobe Photoshop® software. RESULTS: A total of 17 patients 1 to 10 months of age were included, of whom 16 were girls (94%). Fourteen lesions were superficial, and 3 were mixed IH. The median time prior to initiation of treatment was 105 days (44-232). All lesions showed some degree of clearing. The mean of lightening of color intensity observed was of 45% (17%-74%) over the period of follow-up. CONCLUSIONS: The colorimetric analysis of the digital images allowed an accurate and objective evaluation of IH clearing.

Metabolomic profiling suggests systemic signatures of premature aging induced by Hutchinson-Gilford progeria syndrome.

INTRODUCTION: Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare genetic disorder. HGPS children present a high incidence of cardiovascular complications along with altered metabolic processes and an accelerated aging process. No metabolic biomarker is known and the mechanisms underlying premature aging are not fully understood. OBJECTIVES: The present work aims to evaluate the metabolic alterations in HGPS using high resolution mass spectrometry. METHODS: The present study analyzed plasma from six HGPS patients of both sexes (7.7 ± 1.4 years old; mean ± SD) and eight controls (8.6 ± 2.3 years old) by LC-MS/MS in high-resolution non-targeted metabolomics (Q-Exactive Plus). Targeted metabolomics was used to validate some of the metabolites identified by the non-targeted method in a triple quadrupole (TSQ-Quantiva). RESULTS: We found several endogenous metabolites with statistical differences between control and HGPS children. Multivariate statistical analysis showed a clear separation between groups. Potential novel metabolic biomarkers were identified using the multivariate area under ROC curve (AUROC) based analysis, showing an AUC value higher than 0.80 using only two metabolites, and tending to 1.00 when increasing the number of metabolites in the AUROC model. Taken together, changed metabolic pathways involve sphingolipids, amino acids, and oxidation of fatty acids, among others. CONCLUSION: Our data show significant alterations in cellular energy use and availability, in signal transduction, and lipid metabolites, adding new insights on metabolic alterations associated with premature aging and suggesting novel putative biomarkers.

Majocchi granuloma on a child's face.

Majocchi granuloma (MG) is a rare dermal and subcutaneous fungal infection. We report a rare case of MG on the face of a six-year-old child caused by Trichophyton mentagrophytes after long term use of topical corticosteroids and other inadequate topical medications. He was treated with griseofulvin 25 mg/kg/day for 35 days unsuccessfully and successful treatment was obtained with terbinafine.

Multifocal Congenital Hemangiopericytoma.

Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported.

Serum Vitamin D Levels Not Associated with Atopic Dermatitis Severity.

BACKGOUND/OBJECTIVES: The objective of the current study was to determine the relationship between serum vitamin D levels and the severity of atopic dermatitis (AD) in a Brazilian population. METHODS: This was a cross-sectional study of patients younger than 14 years of age seen from April to November 2013. All patients fulfilled the Hanifin and Rajka Diagnostic Criteria for AD diagnosis. Disease severity was determined using the SCORing Atopic Dermatitis index and classified as mild (<25), moderate (25-50), or severe (>50). Serum vitamin D levels were classified as sufficient (≥30 ng/mL), insufficient (29-21 ng/mL), or deficient (≤20 ng/mL). RESULTS: A total of 105 patients met the inclusion criteria. Mild AD was diagnosed in 58 (55.2%) children, moderate in 24 (22.8%), and severe in 23 (21.9%). Vitamin D deficiency was observed in 45 individuals (42.9%). Of these, 24 (53.3%) had mild AD, 13 (28.9%) moderate, and 8 (17.7%) severe. Insufficient vitamin D levels were found in 45 (42.9%) individuals; 24 (53.3%) had mild AD, 9 (20.0%) moderate, and 12 (26.7%) severe. Of the 15 individuals (14.2%) with sufficient vitamin D levels, 10 (60.7%) had mild AD, 2 (13.3%) moderate, and 3 (20.0%) severe. The mean vitamin D level was 22.1 ± 7.3 ng/mL in individuals with mild AD, 20.8 ± 6.5 ng/mL in those with moderate AD, and 21.9 ± 9.3 ng/mL in those with severe AD. Variables such as sex, age, skin phototype, season of the year, and bacterial infection were not significantly associated with vitamin D levels. CONCLUSION: Levels of 25-hydroxyvitamin D were deficient or insufficient in 85% of the children, but serum vitamin D concentrations were not significantly related to AD severity.

Nappy (diaper) rash: what else besides irritant contact dermatitis?

Nappy (diaper) rash is a common cutaneous disorder of infancy, and diverse dermatoses may affect this region. To perform a differential diagnosis can be challenging. We present four cases to emphasise the importance of clinical diagnosis.

Open season: select the best 'beast' for each skin lesion.

Animal bites can cause skin lesions that suggest other conditions, and therefore diagnosis can be a challenge. Four cases of skin injuries caused by arthropods are presented below.

WhatsApp and atopic dermatitis: a clinical trial.

OBJECTIVE: To evaluate the effect of text messages with information about atopic dermatitis (AD) on the quality of life (QoL) of children and their caregivers and on the severity of the disease. METHODS: Researcher-blinded randomized controlled clinical trial. The experimental group (EG) received messages about AD and the control group (CG) about general health. A total of 56 children under 15 years of age and their caregivers, allocated to the CG and EG, were assessed on admission, after one month, and after four months. Improvement in QoL was measured by the Children's Dermatology Life Quality Index (CDLQI), the Infants' Dermatitis Quality of Life Index (IDQOL), and the Dermatitis Family Impact Questionnaire (DFIQ), and improvement in the severity of AD by the Scoring of Atopic Dermatitis (SCORAD) and the Eczema Area and Severity Index (EASI). RESULTS: Median age was of nine years, 33 (58.9 %) were girls. The CG and EG had similar results, except for the higher frequency of mild AD in the CG and moderate/severe AD in the EG-these severity categories were kept grouped together. Regarding mild and moderate/severe AD in the EG, the SCORAD score decreased (p = 0.03 and p < 0.001). The EASI in both groups showed a significant reduction (mild AD: CG: p = 0.01, EG: p = 0.04; moderate/severe AD: CG: p = 0.05, EG: p = 0.02). The QoL of children and caregivers improved only in the EG (p = 0.01). Intergroup analysis showed no differences. CONCLUSION: The improvement in the severity of AD in both groups suggests the positive effects of educational interventions in general, not only those specific to the disease.

Let's Play? A Board Health Game Development and Validation for Children with Atopic Dermatitis.

Objective: Several health games have been developed for pediatric patients in recent years but few for children with atopic dermatitis (AD). As this chronic disease requires changes in daily habits, this study aimed to develop and validate the content of a board health game for children with AD. Material and Methods: This is a content development and validation study of DermatrilhaTM, a board health game about AD. The instrument aims to promote interactions between children with AD and health care providers and offers the exchange of experiences, feelings, and knowledge about the disease in a playful way. The five stages of development of the board game were (a) planning, (b) development, (c) preparation of content validation questionnaires, (d) evaluation by a committee of experts, and (e) pretest with the target audience. Results: The expert committee group consisted of 20 professionals: 5 physicians specialized in pediatric dermatology, 5 psychologists specialized in health psychology, 5 designers with experience in illustration, and 5 early childhood educators. The target audience consisted of 25 children aged 7-12 years with AD. The evaluation of the expert committee found 0.95 in the general content validity index and 0.92 in the target audience, thus exceeding 0.80 in all items. Conclusion: The board health game Dermatrilha has proven to be a psychoeducational tool for the therapeutic education of children with AD, enabling the exchange of experiences, feelings, and knowledge about the disease among peers and health care providers.

What the skin of 341 premature newborns says - a transversal study.

OBJECTIVES: Determine the frequency of dermatological diagnoses in preterm newborns up to 28 days of life and associated perinatal factors. METHOD: a cross-sectional analytical study with a convenience sample and prospective data collection, was conducted between November 2017 and August 2019. Overall, 341 preterm newborns who had been admitted to a University hospital - including those admitted to the Neonatal Intensive Care Unit - were evaluated. RESULTS: 61 (17.9%) had less than 32 weeks gestational age (GA), with a mean GA and birth weight of 33.9 ± 2.8 weeks and 2107.8 ± 679.8g (465 to 4230g), respectively. The median age at the time of evaluation was 2.9 days (4 h to 27 days). The frequency of dermatological diagnoses was 100% and 98.5% of the sample had two or more, with an average of 4.67+1.53 dermatoses for each newborn. The 10 most frequent diagnoses were lanugo (85.9%), salmon patch (72.4%), sebaceous hyperplasia (68.6%), physiological desquamation (54.8%), dermal melanocytosis (38.7%), Epstein pearls (37.2%), milia (32.2%), traumatic skin lesions (24%), toxic erythema (16.7%), and contact dermatitis (5%). Those with GA< 28 weeks showed more traumatic injuries and abrasions, whereas those with ≥ 28 weeks had physiological changes more frequently, and those with GA between 34-366/7 weeks, had transient changes. CONCLUSION: Dermatological diagnoses were frequent in our sample and those with higher GA showed a higher frequency of physiological (lanugo and salmon patch) and transient changes (toxic erythema and miliaria). Traumatic lesions and contact dermatitis were among the 10 most frequent injuries, reinforcing the need to effectively implement neonatal skin care protocols, especially in preterm.

Randomized trial with soaps - what happens to a newborn baby's skin?

OBJECTIVE: Evaluate the effectiveness of a children's soap with physiological pH in maintaining cutaneous pH and moisture of the newborn (NB)'s skin after the first bath. METHODS: Randomized, controlled and double-blind clinical trial in a rooming-in of a tertiary maternity hospital in southern Brazil with 204 newborns > 34 gestational weeks. Gestational and obstetric history was evaluated, and newborns were randomized into two groups according to the product applied in the bath: the control group (CG), which used common liquid soap with pH 7.0 and experimental group (EG), which used children's liquid soap with pH 5.8. Evaluation was made immediately before and after bath with skin pH measurement, corneometry and clinical parameters (erythema, scaling and moisture), on the forehead, abdomen and thigh. RESULTS: There was no difference between groups regarding gestational, obstetric and family history (p > 0.05). In CG, skin pH increased in the abdomen and thigh (p < 0.05). In EG there was an improvement in clinical parameters after bathing with: increased moisture, less erythema and less scaling (p < 0.05). On the forehead, there was a significant increase in pH after bathing (p < 0.001) similar in both groups, although no use of soap. There was no difference in corneometry between groups after bathing. CONCLUSION: Children's liquid soap with physiological pH maintained the acidic skin pH and moisture of the newborn's skin after the first bath, which reinforces the importance of using products with physiological pH in the hygiene of newborns. Registration number RBR-9ky84vd.

Parry Romberg disease with En Coup de Sabre Scleroderma: Effect of tocilizumab on periodontal bone inflammation.

Parry Romberg disease and En Coupe de Sabre Scleroderma are frequently associated disorders that affect the face and can cause severe aesthetic and functional impairment. Systemic immunosuppression is the gold standard of first-line treatment in the pediatric rheumatology standpoint although it is often delayed in the pediatric dermatology clinics and more often used in cases of refractory neurological impairment. We report on a case with dental root resorption and severe periodontal bone inflammation detected on magnetic resonance imaging, which was successfully treated with the anti-IL-6 agent tocilizumab.

Educational intervention and atopic dermatitis: impact on quality of life and treatment.

BACKGROUND: Educational intervention (EI) could improve understanding of atopic dermatitis (AD) and adherence to treatment, decreasing severity, and improving quality of life (QoL). OBJECTIVE: This study aims to evaluate the influence of an EI on the severity of the disease and on the QoL in children with AD. METHODS: A controlled clinical trial was performed, including children up to 14 years of age with AD. Patients were allocated into control group (CG), which received usual guidelines on AD during the outpatient visit, and a study group (SG) that, in addition to the usual guidelines, participated in the EI. The severity of AD was assessed by Scoring Atopic Dermatitis (SCORAD) and Eczema Area and Severity Index (EASI). QoL was assessed by the Children's Dermatology Life Quality Index and the Dermatitis Family Impact Questionnaire. RESULTS: Twenty-seven participants were included in the CG and 21 in the SG. There was a decrease in the median value for the QoL of children in the SG after the intervention (p = 0.04), as well as in the caregiver's (p = 0.04). In the CG, the median QoL of children and caregivers remained unaltered, for caregivers the median value for the QoL was equal throughout first and second evaluation (p = 0.32). In the SG, EASI values decreased after the intervention (p = 0.04), as well as SCORAD (p = 0.04). The CG did not show any decrease in the values of EASI (p = 0.88) scores nor of SCORAD scores (p = 0.82). CONCLUSION: The EI rendered a decrease in severity of the disease and improvement in the QoL of patients and their caregivers.

An inflammatory reaction surrounding molluscum contagiosum as possible manifestation of immune reconstitution inflammatory syndrome in HIV infection.

Highly active antiretroviral therapy can restore specific immune responses and control of microorganism infections in human immunodeficiency virus-positive patients. This immune recovery may cause an inflammatory reaction to microbial and autoimmune antigens known as immune reconstitution inflammatory syndrome. We describe a clinical case with an intense inflammatory response surrounding molluscum contagiosum after highly active antiretroviral therapy. The clinical and laboratory findings suggested that the reaction was due to immune reconstitution inflammatory syndrome occurring during a period of immune recovery in a child with acquired immune deficiency syndrome.

Laboratorial atopy markers in children with human immunodeficiency virus.

Changes in immune system functions are one of the most important consequences of human immunodeficiency virus (HIV) infection. Studies have reported a higher prevalence of disease mediated by immunological hypersensitivity mechanisms in HIV-positive patients. This study aims to observe how immunological changes in HIV-infected children interfere in atopy determinants. Fifty-seven HIV-positive children were studied between June 2004-August 2005 to evaluate the possible modifications in atopy diagnosis from prick test environmental allergen reactivity. Patients were subjected to two evaluations: on both occasions, atopic and non-atopic groups were correlated with immunological (CD4+ and CD8+ lymphocyte concentrations and serum levels of IgA, IgM, IgG and IgE) and viral parameters (HIV viral load). The percent atopy was 20.05 in the first and 29.82 in the second evaluation and atopy was diagnosed in patients without immunosuppression or with moderate immunosuppression. Six patients changed from a negative to a positive atopy profile. One patient with a decreased CD4+ T lymphocyte concentration failed to demonstrate prick test positivity between evaluations. Multivariate analysis showed that the variables associated with atopy diagnosis included a personal history of allergic diseases as well as elevated IgE for age and elevated IgE levels. Atopy development in HIV-infected children seems to be modulated by genetic and environmental factors as well as immunological condition.
