Abstract
Potato wart disease is caused by the obligate fungal pathogen Synchytrium endobioticum. DNA extraction from compost, purified spores and crude wart tissue derived from tuber galls of infected potatoes often results in low S. endobioticum DNA concentration or highly contaminated with DNA coming from other microorganisms and the potato host. Therefore, Illumina sequencing of these samples generally results in suboptimal recovery of the nuclear genome sequences of S. endobioticum. A hybridization-based target enrichment protocol was developed to strongly enhance the recovery of S. endobioticum DNA while off-target organisms DNA remains uncaptured. The design strategy involved creating a set of 180,000 molecular baits targeting both gene and non-gene regions of S. endobioticum. The baits were applied to whole genome amplified DNA samples of various S. endobioticum pathotypes (races) in compost, from purified spores and crude wart tissue samples. This was followed by Illumina sequencing and bioinformatic analyses. Compared to non-enriched samples, target enriched samples: 1) showed a significant increase in the proportion of sequenced bases mapped to the S. endobioticum nuclear genome, especially for crude wart tissue samples; 2) yielded sequencing data with higher and better nuclear genome coverage; 3) biased genome assembly towards S. endobioticum sequences, yielding smaller assembly sizes but higher representation of putative S. endobioticum contigs; 4) showed an increase in the number of S. endobioticum genes detected in the genome assemblies. Our hybridization-based target enrichment protocol offers a valuable tool for enhancing genome sequencing and NGS-based molecular detection of S. endobioticum, especially in difficult samples.

Abstract
Epidermodysplasia verruciformis (EV) is a rare inherited immune disease characterized by pityriasis versicolor-like macules, hyperpigmented or hypopigmented warty papules and irregular reddish-brown plaques, mainly on the face, neck and extremities. Some therapeutic options include medications, lifestyle changes, ALA-PDT, surgery and so on. But there is no cure for EV and thus the clinical management is challenging. We report a case of EV that was refractory to multiple therapies and achieved an encouraging result with a combination therapy of surgery and 5-aminolevulinic acid photodynamic therapy (ALA-PDT).

Abstract
BACKGROUND AND AIMS Sexually transmitted infections (STIs) are a significant global public health challenge due to their high incidence rate and potential for severe consequences when early intervention is neglected. Research shows an upward trend in absolute cases and DALY numbers of STIs, with syphilis, chlamydia, trichomoniasis, and genital herpes exhibiting an increasing trend in age-standardized rate (ASR) from 2010 to 2019. Machine learning (ML) presents significant advantages in disease prediction, with several studies exploring its potential for STI prediction. The objective of this study is to build males-based and females-based STI risk prediction models based on the CatBoost algorithm using data from the National Health and Nutrition Examination Survey (NHANES) for training and validation, with sub-group analysis performed on each STI. The female sub-group also includes human papilloma virus (HPV) infection. METHODS The study utilized data from the National Health and Nutrition Examination Survey (NHANES) program to build males-based and females-based STI risk prediction models using the CatBoost algorithm. Data was collected from 12,053 participants aged 18 to 59 years old, with general demographic characteristics and sexual behavior questionnaire responses included as features. The Adaptive Synthetic Sampling Approach (ADASYN) algorithm was used to address data imbalance, and 15 machine learning algorithms were evaluated before ultimately selecting the CatBoost algorithm. The SHAP method was employed to enhance interpretability by identifying feature importance in the model's STIs risk prediction. RESULTS The CatBoost classifier achieved AUC values of 0.9995, 0.9948, 0.9923, and 0.9996 and 0.9769 for predicting chlamydia, genital herpes, genital warts, gonorrhea, and overall STIs infections among males. The CatBoost classifier achieved AUC values of 0.9971, 0.972, 0.9765, 1, 0.9485 and 0.8819 for predicting chlamydia, genital herpes, genital warts, gonorrhea, HPV and overall STIs infections among females. The characteristics of having sex with new partner/year, times having sex without condom/year, and the number of female vaginal sex partners/lifetime have been identified as the top three significant predictors for the overall risk of male STIs. Similarly, ever having anal sex with a man, age and the number of male vaginal sex partners/lifetime have been identified as the top three significant predictors for the overall risk of female STIs. CONCLUSIONS This study demonstrated the effectiveness of the CatBoost classifier in predicting STI risks among both male and female populations. The SHAP algorithm revealed key predictors for each infection, highlighting consistent demographic characteristics and sexual behaviors across different STIs. These insights can guide targeted prevention strategies and interventions to alleviate the impact of STIs on public health.

Abstract
BACKGROUND It has been reported that programmed death-ligand 1 (PD-L1) is highly expressed in cells during viral infection, which helps the virus escape host immunity. However, the relationship between human papillomavirus (HPV) and PD-L1 in condyloma acuminatum and whether they participate in immunosuppression have not been reported. In this paper, we aimed to explore the expression and significance of PD-L1 in condyloma acuminatum. METHODS The expression of PD-L1 in the wart of condyloma acuminatum patients and the foreskin of healthy individuals was evaluated. Lentivirus transfection was used to introduce the HPV11-E7 gene into HaCaT cells to investigate whether HPV infection could affect the expression of PD-L1. The successfully constructed HPV11-E7 HaCaT cells were cocultured with Jurkat cells, and Jurkat cell apoptosis and proliferation as well as the Jurkat cell cycle were evaluated by flow cytometry and cell counting kit-8 (CCK-8) assays. RESULTS PD-L1 was highly expressed in keratinocytes of genital warts. Through the construction of a cell model, we found that HPV11-E7 could upregulate the expression of PD-L1 in HaCaT cells. Furthermore, HPV11-E7 HaCaT cells can promote the apoptosis of Jurkat cells, inhibit the proliferation of Jurkat cells and mediate the cell cycle arrest of Jurkat cells through the PD-1/PD-L1 signalling pathway. CONCLUSIONS HPV infection may upregulate PD-L1 expression in the keratinocytes of genital warts and participate in the inhibition of local T-cell function.

Abstract
The Korean Association of Urogenital Tract Infection and Inflammation and the Korea Disease Control and Prevention Agency regularly update, revise, and develop new content for the Korean sexually transmitted infection (STI) guidelines. These professional bodies respond to changing epidemiological trends and evolving scientific evidence, and consider advances in laboratory diagnostics and research. The principal recommendations of the 2023 Korean STI guidelines in terms of viral infection follow: 1) If genital herpes recurs more than 4-6 times annually, suppressive therapy with acyclovir 400 mg orally 2 times/day or famciclovir 250 mg orally 2 times/day or valacyclovir 500 mg orally once a day (for patients with <10 episodes/year) or valacyclovir 1 g orally once daily (for patients with ≥10 episodes/year) is recommended to prevent recurrence; 2) molecular human papillomavirus (HPV) testing is not recommended as a routine test for STI status, nor for determination of HPV vaccination status; and 3) patients should inform their current sexual partners about anogenital warts because the types of HPV that cause such warts can be passed to partners. These guidelines will be updated every 5 years and will be revised when new knowledge on STIs becomes available and there is a reasonable need to improve the guidelines. Physicians and other healthcare providers can use the guidelines to assist in the prevention and treatment of STIs.

Abstract
Off-label prescription in paediatric patients is common, where some studies indicate that dermatological conditions are more prone to off-label treatment. This is the first study to analyse the prevalence of off-label prescription in paediatric dermatology consultation. This retrospective observational study was performed using the medical records of paediatric patients who were evaluated in a paediatric dermatological consultation in Pontevedra University Hospital, Pontevedra, Spain. Of the 468 patients reviewed, 186 prescriptions were issued and 51.10% were off-label prescription drugs. The dermatological conditions for which off-label prescription was most common were atopic dermatitis (29.0%), followed by warts (12.9%) and infantile haemangiomas (11.8%). With respect to drugs, topical tacrolimus (23.7%) was the most frequently prescribed off-label drug. The main reason for prescribing an off-label drug was for a disease not included on the label (62.4%), followed by issuing it at a lower age than authorized (55.9%). There was a significant association between a higher percentage of off-label prescription and younger age (p < 0.001), and the treatment of vitiligo, infantile haemangiomas and warts (p < 0.001). Likewise, the off-label prescription was significantly more common in the case of topical terbinafine, timolol, desloratadine and topical salicylic acid (p < 0.001). To conclude, off-label prescription is predominant in paediatric dermatology, as observed in 51.1% of our patients.

Abstract
BACKGROUND Spectrophotometric intracutaneous analysis (SIAscopy) is a non-invasive computerized method that provides insights beyond dermoscopic examination. This study aimed to show the various findings of the plantar verrucae with the SIAscopy evaluation, which displays the chromophores of the skin, melanin, hemoglobin, and collagen. METHODS Plantar verrucae lesions scanned using SIAscopy, and their color, total melanin, dermal melanin, collagen, and blood views were recorded on a computer. These SIAgraphs were examined individually and compared to dermoscopic literature findings. RESULTS The results of color view were in conformity with dermoscopic findings reported in the literature. Among the findings detected for the first time by a SIAscopic examination, a white halo around the vessel in view of total melanin, effacement in the keratinized areas, and whitening in the vascular areas were noted. There was a mottled collagen condensation, which was believed to be induced by dermal papillomatosis in the lesions in the view of collagen, and consequently, as a result of remittent light reflections due to the collagen structure in this area. There was a clarification in the vascular structures that were noticed in the color view in the blood view. It was noted that vascular structures that have not yet been thrombosed under the thickened epidermis could not be detected in color view. CONCLUSION Our study reveals that SIAscopy, a rapid, non-invasive, and easy-to-use examination method similar to dermoscopy, can also diagnose other skin diseases, particularly pathogenetic processes that induce epidermal and papillary dermis changes, apart from pigmented lesions.

Abstract
Skin warts are ubiquitous, self-limiting, benign neoplasms caused by human papillomaviruses (HPV). Several studies have investigated the prevalence and diversity of HPV types in the three main types of skin warts: common, plantar, and flat warts. Using different methodological approaches and diverse populations, several HPV types were detected in skin warts, but often the etiological link remained unconfirmed. This review addresses recently improved multiple strategies for investigating the presence of HPVs in skin warts, covering proper sampling techniques for HPV testing, choice of molecular method(s) for HPV detection, and assignment of the etiological causality of the tested skin wart to a causative HPV type using cellular viral load estimation. These novel approaches provide useful insight into the range of HPV types causing skin warts and support a refined understanding of their etiology. In addition, we conducted a literature review of the main studies examining HPV prevalence and genotype distribution in common warts, plantar warts, and flat warts. Finally, HPV type-specific histopathological patterns in skin warts are briefly discussed.

Abstract
Treatment of anogenital warts (AGWs) is challenging. Candida antigen immunotherapy has been proven to be a safe and relatively effective therapeutic modality; nevertheless, some patients may experience a partial or no response. Combining Candida antigen with other immunotherapies has been proposed to improve the cure rate. Immunotherapy with human papillomavirus (HPV) vaccines has been tried with conflicting outcomes. This study aimed to assess the efficacy and safety of intralesional Candida antigen, either alone or in combination with intralesional bivalent or quadrivalent HPV vaccines, for treating multiple AGWs. Eighty patients with multiple AGWs were included and randomly assigned to four equal groups: group A treated with intralesional Candida antigen only; group B treated with intralesional bivalent HPV vaccine (Cervarix) and Candida; group C treated with intralesional quadrivalent HPV vaccine (Gardasil) and Candida; and group D (control) treated with intralesional saline. Complete clearance of lesions was detected in 40%, 20%, and 60% of patients in Candida monotherapy, Cervarix/Candida, and Gardasil/Candida groups, respectively, whereas 40%, 60%, and 20% of patients in the three groups, respectively, showed partial response. Only 10% of the control group had a partial response. Therapeutic outcomes were significantly better in the three treatment groups compared to the control group, with no statistically significant difference between the Candida monotherapy group and the combination groups, but the response was significantly better in the Gardasil/Candida group than in the Cervarix/Candida group. No statistically significant difference was found between the studied groups regarding the development of side effects. Moreover, no recurrence was detected in any of the groups throughout the 3-month follow-up period. Based on our results, combining intralesional HPV vaccines with Candida antigen immunotherapy may have no significant benefit for treating multiple AGWs. Candida antigen may be recommended as a relatively effective and inexpensive therapeutic modality. The combination of Gardasil and Candida was also effective but very expensive. The results of the Cervarix/Candida combination were unsatisfactory. This clinical trial was registered and approved prospectively by the ethical review board at Faculty of Medicine, Zagazig University.

Abstract
INTRODUCTION The impact of skin diseases on quality of life varies widely, and some can have an impact similar to that of asthma or cystic fibrosis. MATERIAL AND METHODS We conducted a cross-sectional, observational and descriptive study with the aim of describing the degree to which quality of life was affected in paediatric patients managed in a dermatology clinic by means of the Children's Dermatology Life Quality Index (CDLQI). RESULTS In our study, the skin disease with the greatest impact on quality of life was atopic dermatitis, chiefly on account of symptoms like pruritus and insomnia. It was followed by acne, mainly due to the associated negative feelings (shame, sadness, etc.). Quality of life in patients with viral warts and molluscum contagiosum was mostly affected by the treatment, chiefly based on cryotherapy. Most patients with nevi or café-au-lait spots did not have a decreased quality of life, although up to one third of them had negative feelings in relation to their skin disease. DISCUSSION Atopic dermatitis was the common skin disease that caused the greatest impairment in quality of life in our sample, although other diseases also had an impact on different dimensions of quality of life. We ought to underscore the recommendation to use less painful treatments than cryotherapy for viral warts and molluscum contagiosum, as the impairment in quality of life in paediatric patients with these conditions was mainly due to the treatment.

Abstract
Quaternary climatic cycles strongly affected the genetic diversification and ranges of organisms, shaping current genetic structures and distribution patterns. Urodeles provide ideal examples for exploring these dynamics over time and across space. In this study, we integrated a phylogeographic approach and ensemble species distribution modeling (eSDM) to infer the historical demography and distribution patterns of the Vietnam warty newt, Paramesotriton deloustali. Mitochondrial data revealed two groups, West and East, which diverged approximately 1.92 million years ago (Mya). Diversification was likely driven by change in the climate during early stages of the Pleistocene, with increasing monsoon and drought intensities. Biogeographic analysis indicated that the newt's current distribution formed as a result of vicariance events. In addition, the two groups occupy distinct ecological niches. Demographic reconstruction showed signs of expansion in the effective population sizes of the two major groups beginning around 0.11 and 0.15 Mya, respectively. However, eSDM showed fluctuating predicted distributions during the last interglacial, last glacial maximum, mid-Holocene, and present. Mountain systems in northern Vietnam are likely to have served as climatic refuges and to have played a crucial role in safeguarding species from the effects of climate change.

Abstract
BACKGROUND IFN-ε is essential in combating viral infections, particularly in epithelial cells and protected mucosal tissues. Its protective effects have been demonstrated against HSV2, Zika virus, HIV and SARS-COV2. However, the specific expression and role of IFN-ε in skin keratinocytes and HPV infection are still not fully understood and require further investigation. OBJECTIVE In this study, we aimed to investigate the functions and expression mechanism of IFN-ε in keratinocytes during HPV infection and the progression of condyloma acuminata. METHODS Keratinocytes isolated from biopsied CA warts and normal skins samples were analyzed by MeRIP-seq analysis. IFN-ε and WTAP in CA warts and normal skins were analyzed by immunostaining and qPCR. RESULTS In this study, we identified IFN-ɛ was markedly upregulated in CA warts and HPV-infected keratinocytes. IFN-ɛ expression also showed negatively correlation with the size of CA warts (R=-0.4646, P = 0.009). IFN-ɛ suppressed the susceptibility of HPV infection directly. m6A analysis reveals WTAP is a key m6A writer promoting the m6A modification of IFNE mRNA. CONCLUSION Our research suggests that IFN-ɛ is an important Type I IFN cytokine involved in the development of genital warts. Furthermore, we found that HPV infection affects the m6A modifications of IFNE through a mechanism dependent on WTAP. This study provides insights into the innate immune response of the host to HPV infection and may contribute to the development of future strategies for regulating innate immunity to treat genital warts.

Abstract
Subepidermal calcified nodule (SCN) is a clinical form of idiopathic calcinosis cutis, which commonly affects children, and presents as yellowish-white lesions involving the face. It is often misdiagnosed for other disorders like warts and molluscum contagiosum and treated by ablative procedures. In such a scenario, lack of histopathological examination makes it difficult to reach the correct diagnosis. We here report a case of SCN which was diagnosed after an excisional biopsy. Further, histopathological finding of dermal calcium deposits must prompt the clinician to rule out other disorders leading to calcinosis cutis, before labelling the case as SCN.

Abstract
SIGNIFICANCE STATEMENT Nuclear exclusion of the cotranscription factor YAP, which is a consequence of activation of the Hippo signaling pathway, leads to FSGS and podocyte apoptosis. Ajuba proteins play an important role in the glomerular filtration barrier by keeping the Hippo pathway inactive. In nephrocytes from Drosophila melanogaster , a well-established model system for podocyte research, Ajuba proteins ensure slit diaphragm (SD) formation and function. Hippo pathway activation leads to mislocalization of Ajuba proteins, decreased SD formation, rearrangement of the actin cytoskeleton, and increased SD permeability. Targeting the kinases of the Hippo pathway with specific inhibitors in the glomerulus could, therefore, be a promising strategy for therapy of FSGS. BACKGROUND The highly conserved Hippo pathway, which regulates organ growth and cell proliferation by inhibiting transcriptional cofactors YAP/TAZ, plays a special role in podocytes, where activation of the pathway leads to apoptosis. The Ajuba family proteins (Ajuba, LIM domain-containing protein 1 (LIMD1) and Wilms tumor protein 1-interacting protein [WTIP]) can bind and inactivate large tumor suppressor kinases 1 and 2, (LATS1/2) two of the Hippo pathway key kinases. WTIP, furthermore, connects the slit diaphragm (SD), the specialized cell-cell junction between podocytes, with the actin cytoskeleton. METHODS We used garland cell nephrocytes of Drosophila melanogaster to monitor the role of Ajuba proteins in Hippo pathway regulation and structural integrity of the SD. Microscopy and functional assays analyzed the interplay between Ajuba proteins and LATS2 regarding expression, localization, interaction, and effects on the functionality of the SD. RESULTS In nephrocytes, the Ajuba homolog Djub recruited Warts (LATS2 homolog) to the SD. Knockdown of Djub activated the Hippo pathway. Reciprocally, Hippo activation reduced the Djub level. Both Djub knockdown and Hippo activation led to morphological changes in the SD, rearrangement of the cortical actin cytoskeleton, and increased SD permeability. Knockdown of Warts or overexpression of constitutively active Yki prevented these effects. In podocytes, Hippo pathway activation or knockdown of YAP also decreased the level of Ajuba proteins. CONCLUSIONS Ajuba proteins regulate the structure and function of the SD in nephrocytes, connecting the SD protein complex to the actin cytoskeleton and maintaining the Hippo pathway in an inactive state. Hippo pathway activation directly influencing Djub expression suggests a self-amplifying feedback mechanism.

Abstract
Dermatosurgery was long considered an isolated, and not always important, discipline within dermatology. As a therapeutic option, it was considered either the gold standard of first-line therapy, for example in basal cell carcinoma surgery and treatment of early-stage melanoma, or the last option, for instance in the treatment of warts. The fact that a profound change has taken place and that dermatosurgery is now an integral, equal, sometimes leading and always significant component of dermatology will be demonstrated in this review using three examples from geriatric dermatology, the treatment of hidradenitis suppurativa (acne inversa), and melanoma therapy. This review is supplemented by a section on the most important technique in dermatosurgery: microscopic (micrographic) surgery or Mohs Surgery.

Abstract
BACKGROUND AND OBJECTIVE HPV (human papillomavirus) is the virus most often responsible for sexually transmitted infections. The burden of HPV-related diseases on hospital resources represents a major public health problem. The objective of this study was to quantify the lifetime economic burden of HPV-related diseases based on hospital resources from the perspective of National Health Service (NHS) in England. METHODS Patients' data were extracted, anonymised and aggregated by NHS digital from Hospital Episode Statistics (HES) database of patients admitted in 2015 and followed for three years. Data on hospitalizations were identified according to the International Classification of Diseases (ICD-10 CM). Health Resource Group (HRG) tariffs and National Reference Costs were used to estimate the hospitalization costs of anal, cervical, genital, oropharyngeal cancers as well as anogenital warts and cervical dysplasia. RESULTS A total of 19,296 hospitalized patients were included in the estimation model, (39% was male and 61% female. At admission, the average age was 60 and 50 years old, respectively). Life-time costs per patients diagnosed with oropharyngeal cancer were £16,911 (£17,142 for male and £16,334 for female), penile cancer £12,539, vaginal cancer £12,676, anal cancer £13.773 (£12,590 for male, £14,525 for female). Cervical cancer accounted for £12,721, whereas cervical dysplasia for £3932. Resource used for hospitalized patients with anogenital warts was equal to £872 (£884 and £856 for men and women, respectively). On average, outpatient accounted for 39% of the total lifetime costs. CONCLUSION The results of this study highlight that a substantial amount of resources is utilized for the treatment of HPV-related diseases at hospital level in England. These measures have the potential to inform policy decisions to ensure an optimal use of the NHS resources.

Abstract
Online sexual health services potentially transform modes of engagement with service users. We report findings from an in-depth interview study with users of a photo-diagnosis service offered by an established UK-based online sexual health service (SH:24). Adopting a sociomaterial theoretical perspective, we analyse the interviews for descriptions of health care with and through the affordances offered by SH:24. We focus on how the interactions of service users and clinicians with nonhuman agents opened or closed off capacities for better health and wellbeing. Our findings explore navigating online and in-person service options; digitising bodies; temporal affordances; the tension between anonymous and personalised care; configuring digital privacy; and when automated care is not enough. We conclude that emerging practices of care within digital health services delivered by more-than-human collaborations reconfigure experiences of diagnosis and treatment and require detailed attention to understand how they create and close down opportunities to improve or maintain health.

Abstract
Ingenol mebutate (IM) is highly effective in the treatment of human papillomavirus (HPV)-induced anogenital warts (AGW) leading to fast ablation within hours. However, the exact mode of action is still largely unknown. We performed dermoscopy, in vivo confocal microscopy (CLM), histology, immunohistochemistry, and immunofluorescence to gain insights in mechanisms of IM treatment in AGW. In addition, we used in vitro assays (ELISA, HPV-transfection models) to further investigate in vivo findings. IM treatment leads to a strong recruitment of neutrophils with thrombosis of small skin vessels within 8 h, in a sense of immunothrombosis. In vivo and in vitro analyses showed that IM supports a prothrombotic environment by endothelial cell activation and von Willebrand factor (VWF) secretion, in addition to induction of neutrophil extracellular traps (NETosis). IM superinduces CXCL8/IL-8 expression in HPV-E6/E7 transfected HaCaT cells when compared to non-infected keratinocytes. Rapid ablation of warts after IM treatment can be well explained by the observed immunothrombosis. This new mechanism has so far only been observed in HPV-induced lesions and is completely different from the mechanisms we see in the treatment of transformed keratinocytes in actinic keratosis. Our initial findings indicate an HPV-specific effect, which could be also of interest for the treatment of other HPV-induced lesions. Larger studies are now needed to further investigate the potential of IM in different HPV tumors.

Abstract
PURPOSE To report the relative incidence of excised pediatric eyelid lesions and describe the correlation between the clinical and pathology diagnosis. METHODS This was a retrospective analysis of 137 consecutive pathology-confirmed eyelid lesions excised at a U.S. quaternary children's hospital system. Chalazion was excluded from this study. RESULTS Benign non-cystic epithelial lesions comprised 48.2% of all excised lesions, followed by mesenchymal (14.6%) and cystic (10.2%) lesions. The most common lesions were molluscum contagiosum (21.9%) and verruca vulgaris (19.0%). Hispanic White race represented 62.0% of cases, followed by non-Hispanic White (23.3%) and Black (8.8%). There were no malignant lesions. A specific preoperative clinical diagnosis was attempted in 70.1% of cases. Of these, 60.4% had a matching histopathology. CONCLUSIONS The authors report a higher proportion of molluscum contagiosum and verruca vulgaris when compared to the literature; these differences may suggest geographic variance, management preference, or a general increase in incidence. Correlation with pathology showed the clinical diagnosis of eyelid lesions can be challenging even for ophthalmologists. However, malignancy in pediatric eyelid lesions is rare and submission for histopathology may be safely omitted, except in cases with atypical features or suspicion for syndromic disease. The decision for surgery should be methodically approached and take into consideration the most likely diagnosis, natural history of the disease, sociopsychological impact, anesthesia risk, and resource burden.

Abstract
Gain-of-function (GOF) mutations in CXCR4 cause WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome, characterized by infections, leukocyte retention in bone marrow (BM), and blood leukopenias. B lymphopenia is evident at early progenitor stages, yet why do CXCR4 GOF mutations that cause B (and T) lymphopenia remain obscure? Using a CXCR4 R334X GOF mouse model of WHIM syndrome, we showed that lymphopoiesis is reduced because of a dysregulated mesenchymal stem cell (MSC) transcriptome characterized by a switch from an adipogenic to an osteolineage-prone program with limited lymphopoietic activity. We identify lymphotoxin beta receptor (LTβR) as a critical pathway promoting interleukin-7 (IL-7) down-regulation in MSCs. Blocking LTβR or CXCR4 signaling restored IL-7 production and B cell development in WHIM mice. LTβR blocking also increased production of IL-7 and B cell activating factor (BAFF) in secondary lymphoid organs (SLOs), increasing B and T cell numbers in the periphery. These studies revealed that LTβR signaling in BM MSCs and SLO stromal cells limits the lymphocyte compartment size.

Abstract
Genital warts are caused by several strains of Human Papilloma Viruses. Although asymptomatic in most cases, they can be psychologically and physically distressing for patients. Recently, intralesional immunotherapy using different antigens—such as Bacille Calmette–Guerin vaccine, candida antigen and measles, mumps, and rubella (MMR) vaccine—have shown promising efficacy in the treatment of genital warts. We report two cases in Omani males who presented to the Dermatology Department at Barka Polyclinic with recalcitrant genital warts that resolved completely with intralesional injection of the MMR vaccine.

Abstract
Given the ubiquity of leukopenia and sinopulmonary infections in childhood, differentiating patients with inborn errors of immunity (IEI) from otherwise healthy patients can be challenging. The diagnostic complexity is further exacerbated in disorders with wide phenotypic variability such as warts, hypogammaglobulinemia, infections, and myelokathexis (WHIM) syndrome. However, using a Sherlock approach with careful attention to details in the patient's medical history and physical examination coupled with a comprehensive family history can heighten the index of suspicion for underlying IEI. Subsequent iterative and deductive reasoning incorporating results from laboratory interrogation, response (or lack thereof) to standard therapy, and emergence of new symptoms can further aid in a timely diagnosis of IEI. Herein, we detail a WHIM syndrome kindred with marked phenotype variability, identified after the presentation of a child with intermittent neutropenia and sinopulmonary infections. The complexity of this kindred highlights the utility of an interspecialty, collaborative Sherlock approach to diagnosis, and care. In addition, the genetic underpinnings, diagnostic approaches, clinical features, supportive care options, and management of WHIM syndrome are reviewed.

Abstract
UNLABELLED Potato wart disease is considered one of the most important quarantine pests for cultivated potato and is caused by the obligate biotrophic chytrid fungus Synchytrium endobioticum. This review integrates observations from early potato wart research and recent molecular, genetic, and genomic studies of the pathogen and its host potato. Taxonomy, epidemiology, pathology, and formation of new pathotypes are discussed, and a model for molecular S. endobioticum-potato interaction is proposed. TAXONOMY Currently classified as kingdom: Fungi, phylum: Chytridiomycota, class: Chytridiomycetes, order: Chytridiales, family: Synchytriaceae, genus: Synchytrium, species: Synchytrium endobioticum, there is strong molecular support for Synchytriaceae to be transferred to the order Synchytriales. HOSTS AND DISEASE SYMPTOMS Solanum tuberosum is the main host for S. endobioticum but other solanaceous species have been reported as alternative hosts. It is not known if these alternative hosts play a role in the survival of the pathogen in (borders of) infested fields. Disease symptoms on potato tubers are characterized by the warty cauliflower-like malformations that are the result of cell enlargement and cell multiplication induced by the pathogen. Meristematic tissue on tubers, stolons, eyes, sprouts, and inflorescences can be infected while the potato root system seems to be immune. PATHOTYPES For S. endobioticum over 40 pathotypes, which are defined as groups of isolates with a similar response to a set of differential potato varieties, are described. Pathotypes 1(D1), 2(G1), 6(O1), and 18(T1) are currently regarded to be most widespread. However, with the current differential set other pathogen diversity largely remains undetected. PATHOGEN-HOST INTERACTION A single effector has been described for S. endobioticum (AvrSen1), which is recognized by the potato Sen1 resistance gene product. This is also the first effector that has been described in Chytridiomycota, showing that in this fungal division resistance also fits the gene-for-gene concept. Although significant progress was made in the last decade in mapping wart disease resistance loci, not all resistances present in potato breeding germplasm could be identified. The use of resistant varieties plays an essential role in disease management.

Abstract
The skin is the largest organ in the human body, and it acts as the barrier between the world and our bodies. As such, it is constantly being exposed to infections, irritants, and allergens. Approximately one-third of primary care visits involve at least one skin complaint. This may manifest as a rash, a lesion, pruritis, pigment changes, or textural abnormalities. Whatever the presentation, it is important to know the common causes of these skin abnormalities and the appropriate management. Just as important as management is the ability to set expectations for patients, as many common skin conditions can be difficult to treat and may take significant time to resolve. This article will highlight some of the most common skin lesions we see in pediatric patients. [Pediatr Ann. 2022;51(1):e2-e5.].

Abstract
OBJECTIVES To evaluate the feasibility and acceptability of a pilot, free, online photodiagnosis service for genital herpes and warts with postal treatment delivered by a specialist digital sexual health service. SETTING An online sexual health service available free of charge in South East London, UK. PARTICIPANTS Routinely collected data from 237 users of the pilot service during the study period and qualitative interviews with a purposive sample of 15 users. INTERVENTION A pilot, free, online photodiagnosis service for genital herpes and warts with postal treatment delivered by a specialist digital sexual health service. PRIMARY AND SECONDARY OUTCOME MEASURES Proportion of users who successfully uploaded photographs and the proportion diagnosed, treated and referred to face-to-face clinical services. User experience of this service. RESULTS The service was accessed by 237 users during the study period with assessment possible for 86% of users based on the photographs provided. A diagnosis of genital herpes or warts was made for 40.5% and 89.6% were subsequently treated through the service. Eighteen per cent were diagnosed as normal/not needing treatment and 42% were signposted to clinic for further clinical assessment.Qualitative data showed that users felt able and willing to provide genital images for diagnosis. Those who were treated or reassured expressed high satisfaction with the service, valuing the convenience, discreetness and support provided. However, users, particularly those who required referral to other services requested more personal and detailed communication when a clinical diagnosis is given remotely. CONCLUSIONS Findings suggest that online photodiagnosis was feasible and acceptable. However, effective and acceptable management of those who require referral needs careful remote communication.

Abstract
BACKGROUND Warts are viral cutaneous infections caused by human papilloma virus (HPV), presented by verrucous growth over the skin surface. The immune response is considered to play a crucial role in HPV clearance. It depends on intact cellular immunity including natural killer (NK) cell and cytotoxic T cells. It has been clarified that T-helper (Th) 1 cytokines (interleukin (IL)-2, interferon-γ, and tumor necrosis factor-a) and IL-17 are involved in HPV clearance. IL-22 is one of IL-10 family of cytokines produced by NK cells, Th1, Th17, and Th22 cells. In the skin, IL-22 reduces keratinocyte cornification and enhances keratinocyte production of antimicrobial peptides. IL-22 overexpression has been demonstrated in various viral infections and skin inflammatory disorders. AIM The aim of this study was to assess serum levels of IL-22 in patients with warts and its association with their different clinical characteristics. METHODS The study included 20 patients with warts and 20 control subjects. Serum concentration of IL-22 was measured by enzyme-linked immune sorbent assay. RESULTS Serum levels of IL-22 were significantly higher in patients with warts than in control subjects (P < .001). The levels were significantly higher in patients with recurrent warts after prior treatment than in patients with first-time warts (P = .007). Moreover, a significant positive correlation was detected between serum levels of IL-22 and the number of warts (P = .017). CONCLUSION Serum level of IL-22 was elevated in patients with warts. Thus, IL-22 may have a crucial role in the antiviral immune response against this infection.

Abstract
BACKGROUND The aim of this study was to present several cases of benign and malignant nipple lesions and contribute to diagnosis and differential diagnosis. METHODS A retrospective study was conducted on 13 patients. All of the patients were evaluated by ultrasonography, and 11 of them had pathological results. We analyzed the clinical and sonographic features. RESULTS There were 3 malignant lesions, 7 benign lesions, and 3 congenital nipple dysplasia, listed as follows:Malignant lesions (n = 3, 23%): Paget's disease (PD, n = 3, 23%). All of the patients with PD showed unilateral nipple erosion, discharge, and pain. The ultrasound showed abundant blood flow (n = 3, 23%); 2 patients (n = 2, 15%) had microcalcifications.Benign lesions (n = 7, 54%): Adenoma of the nipple (n = 2, 15%). One patient (n = 1, 8%) had nipple erosion and discharge. Two patients (n = 2, 15%) had a palpable nodule in the nipple. The ultrasound of both patients (n = 2, 15%) showed regular-shaped, clear border nodule with abundant blood flow (n = 2, 15%).Leiomyoma of the nipple (n = 1, 8%): This male patient was characterized by unilateral nipple enlargement and pain. The ultrasound showed a regular nodule with absent blood flow.Plasma cell mastitis (n = 2, 15%): Two patients showed unilateral nipple inversion and pain. One patient (n = 1, 8%) showed swollen and redness. The 2 patients showed a lesion in the gland around the nipple present as an irregular shape and unclear boundary hypoechoic mass.Nipple wart (n = 2, 15%): Two patients showed a unilateral soft exogenous neoplasm. Both of the patients showed a hypoechoic wart; the echo was similar to the nipple, the border was clear, and had no blood flow in the wart.Nipple Dysplasia (n = 3, 23%): Accessory nipple (n = 3, 23%). Two patients (n = 2, 15%) had accessory nipples in the subcoastal area, 1 patient (n = 1, 8%) in the areolar. All of the patients' sonographic features were the same as the nipple.The positive predict value (PPV) of the clinical symptoms: Erosion and discharge are both 75% (P < 0.05). The PPV of the US manifestations: irregular shape, indictinct margin, abundant blood flow, microcalcification, thicken skin in diagnosing malignant lesions are 60%,60%,60%,100%,100%, respectively (P < 0.05). CONCLUSIONS The characteristic sonographic features together with clinical symptoms contribute to the diagnosis of nipple lesions.

Abstract
Squamous cell carcinoma of the vulva may develop in association or independently of HPV infection. The relationship between pathogenesis, classification, immunohistochemical profile and prognosis has been studied in the literature with some discrepancies. The aim of this study was to observe the classical association of keratinizing carcinomas with the absence of HPV infection and warty and basaloid carcinomas with the presence of this virus. Therefore, we reviewed the clinic, morphology, and immunophenotype of 39 cases. The tumors were histologically classified into classic keratinizing squamous carcinoma (30), warty (5) and basaloid (4). In the statistical analysis, diffuse expression with p16 was significantly associated with younger age (p = 0.0025), presence of high-grade intraepithelial lesion (p < 0.0001), koilocytosis (p = 0.02), and morphological subtype (p = 0.02), and was inversely associated with the expression of p53 (p < 0.0001) and the presence of lichen sclerosus (p = 0.0051). It is curious that 4 keratinizing carcinomas of the cases studied presented coexpression of p16 and p53. Only one warty tumor was negative for p16 and positive for p53, and 9 keratinizing tumors were positive for p16 and negative for p53. Although these findings show that the use of hematoxylin and eosin could correctly define tumors associated with HPV, we strongly suggest the performance of immunohistochemistry, especially in squamous keratinizing classic carcinomas in young patients with a history of HPV.

Abstract
The obligate biotrophic chytrid species Synchytrium endobioticum is the causal agent of potato wart disease. Currently, 39 pathotypes have been described based on their interaction with a differential set of potato varieties. Wart resistance and pathotyping is performed using bioassays in which etiolated tuber sprouts are inoculated. Here, we describe an alternative method in which aboveground plant parts are inoculated. Susceptible plants produced typical wart symptoms in developing but not in fully expanded aboveground organs. Colonization of the host by S. endobioticum was verified by screening for resting spores by microscopy and by molecular techniques using TaqMan polymerase chain reaction and RNAseq analysis. When applied to resistant plants, none of these symptoms were detectable. Recognition of S. endobioticum pathotypes by differentially resistant potato varieties was identical in axillary buds and the tuber-based bioassays. This suggests that S. endobioticum resistance genes are expressed in both etiolated "belowground" sprouts and green aboveground organs. RNAseq analysis demonstrated that the symptomatic aboveground materials contain less contaminants compared with resting spores extracted from tuber-based assays. This reduced microbial contamination in the aboveground bioassay could be an important advantage to study this obligate biotrophic plant-pathogen interaction. Because wart resistance is active in both below- and aboveground organs, the aboveground bioassay can potentially speed up screening for S. endobioticum resistance in potato breeding programs because it omits the requirement for tuber formation. In addition, possibilities arise to express S. endobioticum effectors in potato leaves through agroinfiltration, thereby providing additional phenotyping tools for research and breeding.

Abstract
WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome is a genetic autoimmune disorder that results from gain-of-function mutations in the gene encoding chemokine receptor CXCR4. A previous study characterized a patient with WHIM who underwent a chromothriptic event that resulted in spontaneous deletion of the WHIM allele in a single hematopoietic stem cell and subsequent cure of the disease. In this issue of the JCI, Gao et al. extend this work and show that Cxcl4-haplosufficient bone marrow has a selective advantage for long-term engraftment in murine WHIM models. Moreover, successful engraftment occurred without prior conditioning of recipients. Together, these results have important implications for improving hematopoietic stem/progenitor cell transplant not only for patients with WHIM but also for all patients who may require the procedure.

Abstract
Fine morphology of the frontal filaments (FFs) at all nauplius stages of two barnacle species (Verruca stroemia and Hesperibalanus hesperius) has been investigated by scanning electron microscopy. FFs have been detected at the second nauplius stage and persist during all stages. FFs contain a wide proximal and a fine distal parts, but they are not actually separated as segments of the limbs, and the area between them looks like a single cuticular crease. Apical and subapical pores have been found at the top of each FF in the larvae of both species, which may indicate the chemoreceptor function of these organs.

Abstract
The novel human papillomavirus type 154 (HPV154) was characterized from a wart on the crena ani of a three-year-old boy. It was previously designated as the putative HPV type FADI3 by sequencing of a subgenomic FAP amplicon. We obtained the complete genome by combined methods including rolling circle amplification (RCA), genome walking through an adapted method for detection of integrated papillomavirus sequences by ligation-mediated PCR (DIPS-PCR), long-range PCR, and finally by cloning of four overlapping amplicons. Phylogenetically, the HPV154 genome clustered together with members of the proposed species Gammapapillomavirus 11, and demonstrated the highest identity in L1 to HPV136 (68.6%). The HPV154 was detected in 3% (2/62) of forehead skin swabs from healthy children. In addition, the different detection sites of 62 gammapapillomaviruses were summarized in order to analyze their tissue tropism. Several of these HPV types have been detected from multiple sources such as skin, oral, nasal, and genital sites, suggesting that the gammapapillomaviruses are generalists with a broader tissue tropism than previously appreciated. The study expands current knowledge concerning genetic diversity and tropism among HPV types in the rapidly growing gammapapillomavirus genus.
