Multiple milia in a newborn with congenital malformations: oral-facial-digital syndrome type 1

Nanda A, Sharaf A, Alsaleh QA

Pediatr Dermatol, 2011 4 22;27(6):669-70.
PMID: 21510010

Oral-facial-digital syndrome type 1 (OMIM #311200) is an X-linked dominant, developmental disorder. Among the 13 described clinical variants of oral-facial-digital syndrome, oral-facial-digital syndrome type 1 is of significance to dermatologists due to presence of congenital milia and hypotrichosis, not described in other variants. Since oral-facial-digital syndrome type 1 is genetically a distinct entity, awareness of these features help to clinically delineate this from other variants.
Fulltext A Prospective Survey of Skin Manifestations in Children With Inborn Errors of Immunity From a National Registry Over 17 Years

Al-Herz W, Zainal M, Nanda A

Front Immunol, 2021;12:751469.
PMID: 34659256 DOI: 10.3389/fimmu.2021.751469

Background and Objectives: Reports on skin manifestations in inborn errors of immunity (IEI) are based on retrospective analysis, small series, or isolated case reports. The present prospective study aimed to determine the spectrum of skin manifestations in children with IEI and their relevance to specific molecular defects.
Materials and Methods: The data were obtained from the Kuwait National Primary Immunodeficiency Disorders Registry during the period of 2004-2020.
Results: A total of 313 pediatric cases of IEI, 71% diagnosed at molecular level, were registered with a cumulative follow-up period of 29,734 months. Skin manifestations were seen in 40.3% of the patients, and they were among the presenting manifestations in 33%. Patients with skin manifestations were older at both onset and diagnosis ages of IEI symptoms, but this was statistically significant for the latter only. The diagnosis delay was significantly longer in patients with skin manifestations. There was a statistically significant association between having skin manifestations and IEI category, being more common in patients with complement deficiencies, combined immunodeficiencies, and diseases of immune dysregulation. There was no statistically significant association between having skin manifestations and both gender and survival. Skin infections were the most frequent manifestations followed by eczema and autoimmune associations. Among IEI with more than 10 cases, skin lesions were a consistent finding in dedicator of cytokinesis 8 (DOCK8) deficiency, hyper IgE syndrome, ataxia-telangiectasia, and recombination activation gene (RAG)1 deficiency.
Conclusions: Skin manifestations are common in IEI patients, and they had significant diagnosis delay and referral to specialists. Improvement of awareness about IEI is needed among pediatricians and dermatologists.
Congenital yellow nail syndrome: a case report and its relationship to nonimmune fetal hydrops

Nanda A, Al-Essa FH, El-Shafei WM, Alsaleh QA

Pediatr Dermatol, 2010 Sep-Oct;27(5):533-4.
PMID: 20807364 DOI: 10.1111/j.1525-1470.2010.01259.x

Yellow nail syndrome (YNS) is an uncommon disorder characterized by a triad of nail dystrophy, lymphedema, and pleural effusion. It is rare in children and congenital occurrence of YNS has been very rarely described. We report a 2-year-old Arab boy having congenital yellow nail syndrome with mild facial dysmorphism and bilateral conjunctival pigmentation born to consanguineous parents. One of his older siblings had died of nonimmune fetal hydrops (NIFH). The case supports the genetic basis of yellow nail syndrome with a possible relationship to nonimmune fetal hydrops.

A total of 80 Kuwaiti children with alopecia areata (AA), without clinical evidence of thyroid disease, were screened for the presence of thyroid abnormalities, and 50 unrelated children with AA were tissue typed for human leukocyte antigen (HLA) class I and class II antigens. Thyroid abnormalities were detected in 14 children (17.5%). Among these, 11 children (14%) had thyroid autoantibodies. These observations highlight the significance of screening for thyroid abnormalities in children with chronic, recurrent, and/or extensive disease. The Kuwaiti children with AA were observed to have a significant association with HLA B21 (OR 18.850, 95% CI 4.404-80.677), B40 (OR 6.767, 95% CI 1.818-25.181), and HLA B12 (OR 4.833, 95% CI 1.198-19.505) antigens. These findings differed from those reported elsewhere.

Zein, a protein-based biopolymer derived from corn, has garnered attention as a promising and eco-friendly choice for packaging food due to its favorable physical attributes. The introduction of electrospinning technology has significantly advanced the production of zein-based nanomaterials. This cutting-edge technique enables the creation of nanofibers with customizable structures, offering high surface area and adjustable mechanical and thermal attributes. Moreover, the electrospinning process allows for integrating various additives, such as antioxidants, antimicrobial agents, and flavoring compounds, into the zein nanofibers, enhancing their functionalities for food preservation. In this comprehensive review, the various electrospinning techniques employed for crafting zein-based nanofibers, and we delve into their enhanced properties. Furthermore, the review illuminates the potential applications of zein nanofibers in active and intelligent packaging materials by incorporating diverse constituents. Altogether, this review highlights the considerable prospects of zein-based nanocomposites in the realm of food packaging, offering sustainable and innovative solutions for food industry.

Congenital leukaemia (CL) is a rare malignancy that accounts for < 1% of cases of childhood leukaemias. Leukaemia cutis (LC) refers to cutaneous infiltration with leukaemic cells, and is seen in 30-50% of CL cases. It may precede, follow or occur simultaneously with leukaemia. If left untreated, the prognosis is usually poor, but early diagnosis and treatment may result in a favourable prognosis. We report a case of congenital leukaemia cutis with a progressive, violaceous papulonodular eruption (a 'blueberry muffin' rash), which had been noted at birth, as a presenting sign of acute myeloid leukaemia (AML), which on investigation was classified as AML, FAB M2 type with a t(8; 21)(p11;q22) chromosomal defect. The patient had a favourable response to AML chemotherapy.

Biosynthesis of silver and other metallic nanoparticles is one of the emerging research area in the field of science and technology due to their potentiality, especially in the field of nano-biotechnology and biomedical sciences in order to develop nanomedicine. In our present study, Penicillium decumbens (MTCC-2494) was brought from Institute of Microbial Technology (IMTECH) Chandigarh and employed for extracellular biological synthesis of silver nanoparticles. Ag-NPs formation was appeared with a dark brown color inside the conical flask. Characterization of Ag-NPs were done by UV-Spectrophotometric analysis which showed absorption peak at 430 nm determines the presence of nanoparticles, Fourier transform infrared (FT-IR) spectroscopic analysis, showed amines and amides are the possible proteins involved in the stabilization of nanoparticles as capping agent. Atomic force Microscopy (AFM) confirmed the particle are spherical, size was around 30 to 60 nm and also the roughness of nanoparticles. Field emission scanning electron microscopy (FE-SEM) showed the topology of the nanoparticles and were spherical in shape. The biosynthesis process was found fast, ecofriendly and cost effective. Nano-silver particle was found to have a broad antimicrobial activity and also it showed good enhancement of antimicrobial activity of Carbenicillin, Piperacillin, Cefixime, Amoxicillin, Ofloxacin and Sparfloxacin in a synergistic mode. These Ag-NPs showed good anti-cancer activity at 80 μg·mL(-1)upon 24 hours of incubation and toxicity increases upon 48 hours of incubation against A-549 human lung cancer cell line and the synergistic formulation of the antibiotic with the synthesized nanoparticles was found more effective against the pathogenic bacteria studied.
