Abstract
In the present study, we report a consanguineous Kuwaiti pedigree with pseudo-dominant inheritance of a recessive KRT16 variant in which homozygotes had focal nonepidermolytic palmoplantar keratoderma accompanied by ragged periungual hyperkeratosis. The key value of this submission is that we believe we have identified the first autosomal recessive inherited skin disorder resulting from pathogenic variants in the keratin 16 gene, KRT16. Our findings expand both the genetic basis and phenotypic expression of inherited KRT16-related disorders.

Abstract
We report a 16-year-old adolescent girl with Down syndrome who developed a slowly progressive papulonodular eruption in the inguinal area. Skin biopsy for histopathology showed foci of bony trabeculae with osteoblasts and calcium deposition in the deeper dermis. An association of such lesions with Down syndrome, and the site of involvement, has not been reported previously.

Abstract
Cutaneous tuberculosis (CTB) is an uncommon form of extra-pulmonary tuberculosis accounting for ≤2% of mycobacterium tuberculosis cases and is more often reported from developing countries. Tuberculid, a cutaneous hypersensitivity reaction to mycobacteria or its fragments, is a another rare cutaneous manifestation seen in association with tuberculosis of other organ systems including tuberculous lymphadenitis, pulmonary tuberculosis, etc. Co-occurrence of a tuberculid with CTB is extremely rare. Herein we report a childhood case of lupus vulgaris, a type of CTB, associated with an atypical presentation of tuberculid.

Abstract
CEDNIK syndrome is a rare autosomal recessive syndrome characterized by cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma of which 25 cases from 19 families have been reported to date. It is a progressive neurodegenerative disorder caused by the loss-of-function pathogenic variant of the SNAP29 gene encoding a member of the SNARE family of proteins. We describe two female siblings from a Syrian parent-related family with CEDNIK syndrome due to homozygous pathogenic variant in SNAP29 [c.223delG(p.Val75Serf*28)]. Palmoplantar keratoderma, reported as a cardinal sign in CEDNIK syndrome, was absent in both patients as of the last follow-up, and one of our patients had a verrucous venous malformation, a finding that has not been previously reported.

Abstract
The ASACUSA collaboration produces a beam of antihydrogen atoms by mixing pure positron and antiproton plasmas in a strong magnetic field with a double cusp geometry. The positrons cool via cyclotron radiation inside the cryogenic trap. Low positron temperature is essential for increasing the fraction of antihydrogen atoms which reach the ground state prior to exiting the trap. Many experimental groups observe that such plasmas reach equilibrium at a temperature well above the temperature of the surrounding electrodes. This problem is typically attributed to electronic noise and plasma expansion, which heat the plasma. The present work reports anomalous heating far beyond what can be attributed to those two sources. The heating seems to be a result of the axially open trap geometry, which couples the plasma to the external (300 K) environment via microwave radiation.

Abstract
Rubella virus (RuV) has recently been found in association with granulomatous inflammation of the skin and several internal organs in patients with inborn errors of immunity (IEI). The cellular tropism and molecular mechanisms of RuV persistence and pathogenesis in select immunocompromised hosts are not clear. We provide clinical, immunological, virological, and histological data on a cohort of 28 patients with a broad spectrum of IEI and RuV-associated granulomas in skin and nine extracutaneous tissues to further delineate this relationship. Combined immunodeficiency was the most frequent diagnosis (67.8%) among patients. Patients with previously undocumented conditions, i.e., humoral immunodeficiencies, a secondary immunodeficiency, and a defect of innate immunity were identified as being susceptible to RuV-associated granulomas. Hematopoietic cell transplantation was the most successful treatment in this case series resulting in granuloma resolution; steroids, and TNF-α and IL-1R inhibitors were moderately effective. In addition to M2 macrophages, neutrophils were identified by immunohistochemical analysis as a novel cell type infected with RuV. Four patterns of RuV-associated granulomatous inflammation were classified based on the structural organization of granulomas and identity and location of cell types harboring RuV antigen. Identification of conditions that increase susceptibility to RuV-associated granulomas combined with structural characterization of the granulomas may lead to a better understanding of the pathogenesis of RuV-associated granulomas and discover new targets for therapeutic interventions.

Abstract
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.

Abstract
Abstract
Background
Medical education should equip students with the necessary skills to support the diverse population they treat and work with and be confident to act as an ally for patients and colleagues. We found there to be a gap for a diversity module in the curriculum at Oxford University.
Method
We created a diversity training session for over 300 medical students aiming to;
The course consisted of a series of talks conducted by a senior lecturer on diversity, doctors, patients, and students, followed by small-group case-based teaching facilitated by a final-year medical student and a junior doctor. All facilitators underwent training by a senior lecturer on diversity. The cases encouraged students to reflect on their own personal biases and enact how they would confront discrimination on the wards. Students completed a survey before and after the session, rating self-confidence on six key learning points.
Results
91.4% students agreed the session was useful to their medical training. There was a significant increase in students who felt confident implementing all learning points: defining key terms (post-session: 95.4%, pre-session: 82.3%); understanding health inequalities (post-session: 93%, pre-session: 54.6%); awareness of personal bias (post-session: 87.9%, pre-session: 70%); partaking in allyship (post-session: 95%, pre-session: 89.5%); and being an active bystander (post-session: 91.4%, pre-session: 45.9%). 79.3% felt confident to challenge acts of discrimination (33.6% pre-session).
Conclusions
This session educates and empowers students to challenge acts of discrimination. We recommend the implementation of similar sessions at all medical schools.

Abstract
Autosomal recessive congenital ichthyosis (ARCI) is a rare and heterogeneous skin cornification disorder presenting with generalized scaling and varying degrees of erythema. Clinical manifestations range from lamellar ichthyosis (LI), congenital ichthyosiform erythroderma (CIE) through the most severe form of ARCI, Harlequin ichthyosis (HI). We used homozygosity mapping, whole-exome and direct sequencing to delineate the relative distribution of pathogenic variants as well as identify genotype-phenotype correlations in a cohort of 62 Middle Eastern families with ARCI of various ethnic backgrounds. Pathogenic variants were identified in most ARCI-associated genes including TGM1 (21%), CYP4F22 (18%), ALOX12B (14%), ABCA12 (10%), ALOXE3 (6%), NIPAL4 (5%), PNPLA1 (3%), LIPN (2%) and SDR9C7 (2%). In 19% of cases, no mutation was identified. Our cohort revealed a higher prevalence of CYP4F22 and ABCA12 pathogenic variants and a lower prevalence of TGM1 and NIPAL4 variants, as compared to data obtained in other regions of the world. Most variants (89%) in ALOX12B were associated with CIE and were the most common cause of ARCI among patients of Muslim origin (26%). Palmoplantar keratoderma associated with fissures was exclusively a result of pathogenic variants in TGM1. To our knowledge, this is the largest cohort study of ARCI in the Middle-Eastern population reported to date. Our data demonstrate the importance of population-tailored mutation screening strategies and shed light upon specific genotype-phenotype correlations.

Abstract
The current COVID-19 pandemic is caused by the SARS-CoV-2 coronavirus. The initial recognized symptoms were respiratory, sometimes culminating in severe respiratory distress requiring ventilation, and causing death in a percentage of those infected. As time has passed, other symptoms have been recognized. The initial reports of cutaneous manifestations were from Italian dermatologists, probably because Italy was the first European country to be heavily affected by the pandemic. The overall clinical presentation, course and outcome of SARS-CoV-2 infection in children differ from those in adults, as do the cutaneous manifestations of childhood. In this review, we summarize the current knowledge on the cutaneous manifestations of COVID-19 in children after thorough and critical review of articles published in the literature and from the personal experience of a large panel of paediatric dermatologists in Europe. In Part 1, we discussed one of the first and most widespread cutaneous manifestations of COVID-19, chilblain-like lesions. In this part of the review, we describe other manifestations, including erythema multiforme, urticaria and Kawasaki disease-like inflammatory multisystemic syndrome. In Part 3, we discuss the histological findings of COVID-19 manifestations, and the testing and management of infected children for both COVID-19 and any other pre-existing conditions.

Abstract
BACKGROUND Autoimmune bullous diseases (AIBD) are rare among children. The data describing the overall spectrum and prognosis of pediatric AIBD (pAIBD) are scarce, and there are no established treatment guidelines. OBJECTIVES The present study examined the spectrum, clinical characteristics, and long-term prognosis of pAIBD in a tertiary care pediatric dermatology unit. METHODS Retrospective records of all pAIBD cases (<18 years) registered over a span of 28 years were analyzed. RESULTS Records of 23 cases of pAIBD, including 16 boys and 7 girls, were reviewed. They constituted 8.5% of total AIBD patients from all age groups. Ninety-one percent of patients were of Arab ethnicity. Linear IgA bullous dermatosis was the most prevalent AIBD followed by bullous pemphigoid, bullous lupus erythematosus, and pemphigus variants (pyostomatitis-pyodermatitis vegetans and neonatal pemphigus). The mean age of onset and diagnosis was 6.4 and 7.7 years, respectively. Systemic treatments, including systemic corticosteroids and dapsone, were required in most cases. Intravenous immunoglobulin G (IVIG) was also utilized as second-line therapy. The mean follow-up period was 76 months with 90% of the patients in complete remission. CONCLUSIONS AIBD pose a great challenge among children both in diagnosis and treatment. This study highlights the ethnic variability and underscores the need for additional similar, international studies to achieve a better understanding of the burden related to pAIBD and help establish treatment guidelines.

Abstract
Autosomal recessive congenital ichthyosis (ARCI) manifests with generalized scaling often associated with generalized erythema. Mutations in at least 13 different genes have been reported to cause ARCI. Acral peeling skin syndrome (APSS) is a rare autosomal recessive disorder manifesting with peeling over the distal limbs and dorsal surfaces of hands and feet. APSS is mostly due to mutations in TGM5, encoding transglutaminase 5. Both ARCI and APSS are fully penetrant genetic traits. Here, we describe a consanguineous family in which one patient with mild ARCI was found to carry a homozygous mutation in ALOXE3 (c.1238G > A; p.Gly413Asp). The patient was also found to carry a known pathogenic homozygous mutation in TGM5 (c.1335G > C; p.Lys445Asn) but did not display acral peeling skin. Her uncle carried the same homozygous mutation in TGM5 but carried the ALOXE3 mutation in a heterozygous state and showed clinical features typical of APSS. Taken collectively, these observations suggested that the ALOXE3 mutation suppresses the clinical expression of the TGM5 variant. We hypothesized that ALOXE3 deficiency may affect the expression of a protein capable of compensating for the lack of TGM5 expression. Downregulation of ALOXE3 in primary human keratinocytes resulted in increased levels of corneodesmosin, which plays a critical role in the maintenance of cell-cell adhesion in the upper epidermal layers. Accordingly, ectopic corneodesmosin expression rescued the cell-cell adhesion defect caused by TGM5 deficiency in keratinocytes as ascertained by the dispase dissociation assay. The present data thus provide evidence for phenotypic suppression in a human hereditary skin disorder.

Abstract
Tractional remodeling of collagen fibrils by fibroblasts requires long cell extensions that mediate fibril alignment. The formation of these cell extensions involves flightless I (FliI), an actin-binding protein that contains a leucine-rich-repeat (LRR), which binds R-ras and may regulate cdc42. We considered that FliI interacts with small GTPases and their regulators to mediate assembly of cell extensions. Mass spectrometry analyses of FliI immunoprecipitates showed abundant Ras GTPase-activating-like protein (IQGAP1), which in immunostained samples colocalized with FliI at cell adhesions. Knockdown of IQGAP1 reduced the numbers of cell extensions and the alignment of collagen fibrils. In experiments using dominant negative mutants, cdc42 activity was required for the formation of short extensions while R-ras was required for the formation of long extensions. Immunoprecipitation of wild-type and mutant constructs showed that IQGAP1 associated with cdc42 and R-ras; this association required the GAP-related domain (1004–1237 aa) of IQGAP1. In cells transfected with FliI mutants, the LRR of FliI, but not its gelsolin-like domains, mediated association with cdc42, R-ras, and IQGAP1. We conclude that FliI interacts with IQGAP1 and co-ordinates with cdc42 and R-ras to control the formation of cell extensions that enable collagen tractional remodeling.

Abstract
PURPOSE Localized autosomal recessive hypotrichosis (LAH) has been associated with pathogenic variants in DSG4, encoding a desmosomal protein as well as in LIPH and LPAR6, encoding respectively lipase H, which catalyzes the formation of 2-acyl-lysophosphatidic acid (LPA), and lysophosphatidic acid receptor 6, a receptor for LPA. LPA promotes hair growth and differentiation. In this study we aimed at delineating the genetic basis of LAH in patients without pathogenic variants in these three genes. METHODS Variant analysis was conducted using exome and direct sequencing. We then performed quantitative reverse transcription polymerase chain reaction (RT-qPCR), immunofluorescence staining, immunoblotting, enzymatic, and coimmunoprecipitation assays to evaluate the consequences of potential etiologic variants. RESULTS We identified homozygous variants in C3ORF52 in four individuals with LAH. C3ORF52 was found to be coexpressed with lipase H in the inner root sheath of the hair follicle and the two proteins were found to directly interact. The LAH-causing variants were associated with decreased C3ORF52 expression and resulted in markedly reduced lipase H-mediated LPA biosynthesis. CONCLUSION LAH can be caused by abnormal function of at least three proteins which are necessary for proper LPA biosynthesis.

Abstract
BACKGROUND Epidermolysis bullosa (EB) is a clinically and genetically heterogeneous blistering skin disease, but in countries such as Kuwait, there are very limited data on the clinical and molecular pathology of EB. To improve understanding of EB in Kuwait, we report the experience of a local tertiary referral center over a 17.5 year period (January 2000-June 2017) in establishing clinical and molecular diagnoses. METHODS Review of hospital records and diagnostic reports. Individual cases were diagnosed by combinations of clinical assessment, skin biopsy (immunohistochemistry and transmission electron microscopy), Sanger sequencing of EB genes, and whole exome sequencing. RESULTS Fifty-four families with EB were registered with the clinic over this period, 41 of whom (84 patients) participated in diagnostic studies. Thirty-seven of these 41 families had consanguineous marriages; 34 had recessive forms of EB, while only seven had dominant subtypes. Recurrent mutations were observed in epidermal dystonin, transglutaminase 5, and type VII collagen. CONCLUSIONS The prevalence of EB in Kuwait is approximately three times that of internationally cited rates with an over-representation of autosomal recessive variants. Establishing the molecular basis of EB in Kuwait with accurate diagnostic subtyping provides a basis for determining healthcare requirements and improving patient management of EB.

Abstract
BACKGROUND/OBJECTIVES Allogeneic hematopoietic stem cell transplantation (HSCT) is a treatment option for many life-threatening disorders in children. Chronic graft-versus-host disease (cGVHD) is a significant complication of HSCT, and its treatment is challenging. Skin is the most common organ affected in cGVHD, with protean manifestations posing a challenge in diagnosis and management. The objective was to have a better understanding of the spectrum of chronic cutaneous GVHD (cc-GVHD) in children. METHODS Hospital records of 14 children with cc-GVHD, registered over 9 years, were reviewed. RESULTS All the patients had received HSCT from related donors. Median duration between HSCT and onset of cc-GVHD was 7.5 months. Eighty-six percent of the patients had a prior history of aGVHD, and 14% had de novo onset of cc-GVHD. Of 14 patients, 71% had classic cc-GVHD. Overlap syndrome was observed in 29%. Tandem occurrence of multiple morphologies was noticed in 6 (43%) patients. Of classic cc-GVHD, lichen planus-like cc-GVHD was most common (57%) followed by scleroderma-like (29%) and poikiloderma (7%). Rare variants included eczema-like (14%) and psoriasis-like (7%) cc-GVHD. Mucosal involvement was seen in 78.6% of the patients, nail involvement in 50%, and hair abnormalities in 43%. After a median follow-up of 4.8 years, complete remission was observed in 50% and mortality in 14%. CONCLUSION The study signifies the diverse nature of cc-GVHD and indicates the need for multicenter surveys including larger number of patients to have proper insight into and develop treatment guidelines for cc-GVHD in children.

Abstract
Inherited retinal diseases are thought to be the leading cause of sight loss in the working age population. Mutations found in the RPGR and CHM genes cause retinitis pigmentosa (RP) and choroideremia, respectively. In the first instance, an X-linked family history of visual field loss commonly raises the suspicion of one of these two genes. In choroideremia, the classic description of a white fundal reflex secondary to the widespread chorioretinal degeneration was made over a hundred years ago in Caucasians. But, it is not so obvious in heavily pigmented fundi. Hence, the clinical diagnosis of CHM in non-Caucasian patients may be challenging in the first stages of the disease. Here we report a case of a Southeast Asian gentleman who has a family history of X-linked retinal degeneration and was found to have a confirmed in-frame deletion of 12 DNA nucleotides in exon 15 of the RPGR gene. Later in life, however, his fundal appearance showed unusual areas of circular pigment hypertrophy and clumping. He was therefore tested for carrying a disease-causing mutation in the CHM gene and a null mutation was found. Since gene therapy trials are ongoing for both of these conditions, it has now become critically important to establish the correct genetic diagnosis in order to recruit suitable candidates. Moreover, this case demonstrates the necessity to remain vigilant in the interpretation of genetic results which are inconsistent with clinical features.

Abstract
Hepatoprotective Mongolian prescription II (MPII), a mixture of 18 different medicinal herbs, significantly inhibited the growth of human liver cancer cell lines Huh-7 and HepG2 in vitro with different concentrations; MPII (6mg/mL) inhibited cell proliferation by 80.48%. MPII induced apoptosis in both cell lines, which was observed by light microscopy and flow cytometry. MPII-induced apoptosis and G0/G1 cell cycle arrest were quantified by Annexin V-FITC/PI staining and flow cytometry. At the molecular level, MPII induced caspase-3, caspase-8, caspase-9, and cytochrome c gene expression. In vivo, MPII dramatically inhibited human liver tumor growth in a xenograft model in Kunming mice with no apparent cytotoxicity to the hosts. Apoptotic genes (Bcl-2 and Bax) are up-regulated, suggesting that the ratio of Bcl-2/Bax was statistically significant, indicating that the drugs had affected the expression of apoptosis genes, especially on induce apoptosis gene Bax. We also observed an attenuated effect when MPII was used in combination with chemotherapy drug 5-fluorouracil (5-FU). The mice treated with 5-FU alone did not show a concentration-dependent effect, but 5-FU in combination with MPII displayed concentration-dependent effects on liver cancer cells. Our study suggests that MPII works by inducing apoptosis and cell cycle arrest, and has the potential to be a powerful anticancer agent.
