Congenital syphilis presenting with granulomatous scalp nodules.

We describe a case of congenital syphilis in an adopted infant with a unique dermatologic presentation of scalp granulomas, along with lymphadenopathy, anemia, and elevated liver transaminases. To our knowledge, this cutaneous morphology has not been previously reported in the literature. This case highlights the varied clinical presentation of congenital syphilis and the diagnostic challenge it poses for clinicians, especially in the context of unknown prenatal history/unknown risk factors, or if syphilis is acquired during pregnancy after routine screening is performed.

Photo- and Thermocatalytic CO Methanation: A Comparison of Ni/AlO and Ni-Ce Hydrotalcite-Derived Materials under UV and Visible Light.

Catalysts derived from Ni/Al/Mg/Ce hydrotalcite were prepared via a co-precipitation method, varying the Ce/Al atomic ratio. All of the catalytic systems thus prepared were tested for CO methanation under dark and photocatalytic conditions (visible and ultraviolet) under continuous flow with the light intensity set to 2.4 W cm.

UV- and visible-light photocatalysis using Ni-Co bimetallic and monometallic hydrotalcite-like materials for enhanced CO methanation in sabatier reaction.

The CO catalytic reduction activities of four different Co-modified Ni-based catalysts derived from hydrotalcite-like materials (HTCs) prepared by co-precipitation method were investigated under thermal and photocatalytic conditions. All catalysts were tested from 473 to 723 K at 10 bar (abs). The light intensity for photocatalytic reactions was 2.

Development of High Temperature Water Sorbents Based on Zeolites, Dolomite, Lanthanum Oxide and Coke.

Methanation is gaining attention as it produces green methane from CO and H, through Power-to-Gas technology. This process could be improved by in situ water sorption. The main difficulty for this process intensification is to find effective water sorbents at useful reaction temperatures (275-400 °C).

Graphene-based versus alumina supports on CO methanation using lanthanum-promoted nickel catalysts.

The valorization of CO as a biofuel, transforming it through methanation as part of the power-to-gas (P2G) process, will allow the reduction of the net emissions of this gas to the atmosphere. Catalysts with 13 wt.% of nickel (Ni) loading incorporated into alumina and graphene derivatives were used, and the effect of the support on the activity was examined at temperatures between 498 and 773 K and 10 bar of pressure.

Eosinophilic cellulitis in response to BNT162b2 COVID-19 vaccination.

A 12-year-old boy presented with a 2-week history of persistent pruritic edematous plaques one day after he received the first dose of the BNT162b2 COVID-19 mRNA vaccine. A skin biopsy showed urticarial dermatitis with tissue eosinophilia consistent with a diagnosis of vaccine-associated eosinophilic cellulitis, with polyethylene glycol as a potential trigger.

Atypical keratosis pilaris-like lesions in a patient with Bethlem myopathy.

Bethlem myopathy is a collagen VI-related myopathy. Collagen VI is primarily not only associated with the extracellular matrix of skeletal muscle, but is also found in the skin, blood vessels, and other organs. Dermatologic findings described for Bethlem myopathy include follicular hyperkeratosis and abnormal scar formation, although clinical and histopathologic photographs remain elusive in the literature.

Allergic contact dermatitis to immobilization mask used in radiation therapy.

Thermoplastic masks made of polyester resin are used to immobilize patients receiving radiation therapy. We describe a case of allergic contact dermatitis (ACD) to a thermoplastic mask worn by a child receiving proton beam therapy for treatment of medulloblastoma. ACD to a thermoplastic mask in an adult was first reported in 2018.

A study of deactivation by HS and regeneration of a Ni catalyst supported on AlO, during methanation of CO. Effect of the promoters Co, Cr, Fe and Mo.

Energy storage from renewable sources is possible by chemical procedures, power to gas technology being a possible solution for long-term storage. In this work, CO methanation from a sulphur containing gas was studied, taking into account deactivation of the catalysts and a regeneration process. In order to improve the sulphur resistance of a standard nickel (13%) catalyst supported on alumina, transition metals like molybdenum (Mo), iron (Fe), cobalt (Co) or chromium (Cr), in different proportions (from 4 to 8 wt%) were added to the catalyst formulation.

Heterogeneous Catalyzed Thermochemical Conversion of Lignin Model Compounds: An Overview.

Thermochemical lignin conversion processes can be described as complex reaction networks involving not only de-polymerization and re-polymerization reactions, but also chemical transformations of the depolymerized mono-, di-, and oligomeric compounds. They typically result in a product mixture consisting of a gaseous, liquid (i.e.

Multicatalysis Combining 3D-Printed Devices and Magnetic Nanoparticles in One-Pot Reactions: Steps Forward in Compartmentation and Recyclability of Catalysts.

A tricatalytic compartmentalized system that immobilizes metallic species to perform one-pot sequential functionalization is described: a three-dimensional (3D)-printed palladium monolith, ferritic copper(I) magnetic nanoparticles, and a 3D-printed polypropylene capsule-containing copper(II) loaded onto polystyrene-supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (PS-TBD) allowed the rapid synthesis of diverse substituted 1-([1,1'-biphenyl]-4-yl)-1-1,2,3-triazoles.

Primary cutaneous aspergillosis at the site of cyanoacrylate skin adhesive in a neonate.

Primary cutaneous aspergillosis is a rare but potentially life-threatening disease. We present the case of a premature infant who developed primary cutaneous aspergillosis with Aspergillus niger at the site of a skin abrasion that had been treated with a purple-colored cyanoacrylate product. The infection was treated successfully with gentle debridement of the cyanoacrylate product, followed by intravenous voriconazole and topical fluconazole.

Pediatric penile porokeratosis: A case report.

We present what we believe to be the second case of pediatric penile porokeratosis and the youngest case reported. A 6-year-old boy presented with a pruritic, verrucous growth at the urethral meatus that recurred after two meatotomies. The diagnosis of porokeratosis was confirmed by biopsy.

Extensive orf infection in a toddler with associated id reaction.

Orf is a zoonotic parapoxvirus typically transmitted to humans by a bite from goats or sheep. We present an unusual case of multiple orf lesions on the fingers of a 13-month-old child who was bitten by a goat and subsequently developed progressive swelling, blistering, and necrotic papulonodules of the hand followed by an additional diffuse, pruritic, papular rash. A primary diagnosis of orf infection was confirmed using real-time polymerase chain reaction, and the diffuse eruption was clinically consistent with an id reaction.

Concurrent and longitudinal effects of maternal and paternal warmth on depression symptoms in children and adolescents.

The main aim of this study is to examine the concurrent and longitudinal effects of perceived affection of mothers and fathers separately on the self-reported symptoms of children's depression. Data were obtained from a 3-wave study of 535 families with children (41.3% boys) aged 9-15 years of age.

Sustainable hydrogen production from bio-oil model compounds (meta-xylene) and mixtures (1-butanol, meta-xylene and furfural).

In the present work m-xylene and an equimolecular mixture of m-xylene, 1-butanol and furfural, all of them bio-oil model compounds, were studied in steam reforming (SR) conditions. Three different nickel catalysts, which showed to be active in 1-butanol SR (Ni/Al2O3, Ni/CeO2-Al2O3 and Ni/La2O3-Al2O3), were tested and compared with thermodynamic equilibrium values. Tests were carried out at temperatures from 800 to 600°C at atmospheric pressure with a steam to carbon ratio (S/C) of 5.

"EB, or Not EB?" Neonatal Desquamative Impetigo in a Degloving Pattern.

We present the case of a 7-day-old boy with significant, rapidly spreading blistering and desquamation in a "degloving" pattern on the hands that mimicked epidermolysis bullosa but was ultimately diagnosed as bullous impetigo caused by a clinically aggressive strain of Staphylococcus aureus. Bullous impetigo is a desquamating condition caused by local release of S. aureus exfoliative toxin A and is more commonly seen in children.

Evaluation and treatment of acne from infancy to preadolescence.

Acne vulgaris is a common inflammatory skin condition affecting most individuals at some point during their lives. Although acne is more commonly seen in adolescents, it can be seen in younger patients as well. It can be useful to classify pediatric acne based on the age of presentation as infantile, mid-childhood, or preadolescent.
