Digital Papillary Adenocarcinoma Is HPV-42-Associated and BRAFV600E Negative: Perspectives for Diagnostic Practice

Digital papillary adenocarcinoma (DPAC) is a rare, low-grade sweat gland carcinoma primarily found on the hands, fingers, or toes and predominantly affecting males. Distinguishing DPAC from benign sweat gland tumors can be challenging. We present the case of a 52-year-old patient with a progressive tumor on the finger initially misdiagnosed as a viral wart. Histological examination revealed a cytologically basophilic sweat gland tumor with tubular structures, papillary protrusions, and a characteristic immunohistochemical staining pattern for CK 7 and Actin. HPV-42 positivity and molecular analysis confirmed the diagnosis of DPAC. HPV-42 has been strongly associated with DPAC. Additionally, p16 positivity and BRAFV600E negativity were observed. These findings aid in the differential diagnosis of acral sweat gland tumors and guide clinical management, including with respect to the potential for recurrence and metastasis.

Investigation of Effectiveness of Nowarta110 Against Murine Malignant Melanoma in an Implanted Animal Model.

Melanoma is a prevalent and severe disease, making the development of new treatments essential. Nowata110 has demonstrated significant therapeutic efficacy in phase II clinical study against plantar warts. It has shown promising anti-cancer effects in both in vitro and in vivo studies using HPV-16 and HPV-18-induced cervical cancer models. This study evaluated the effectiveness of Nowarta110 in murine melanoma-implanted animals. Nowata110 is a novel compound composed of colloidal silver and fig extract. Male and female immunodeficient C(Cg)-Cd 79 atm 1 (cre) and immunocompetent BALB/c mice were used. Murine melanoma cancer cells (B16-F10) were implanted subcutaneously in experimental animals. Once the top cross-sectional area of tumors reached a minimum of 5 mm2 and approximately 4 mm depth, mice were anesthetized and treated with Nowarta110 intravenously or intratumorally. Control mice received no treatment. In non-treated immunodeficient mice, tumor growth progressed over five weeks, whereas Nowarta110-treated mice drastically reduced tumor volume until five weeks after treatment was initiated. Similarly, in untreated BALB/c mice, tumor growth persisted over five weeks. However, Nowarta110-treated mice exhibited a notable reduction in tumor size. Although intravenous administration of Nowarta110 did not result in complete tumor regression in immunodeficient mice, it did lead to reduced tumor growth. In BALB/c immunocompetent mice, intravenous treatment generally stalled tumor progression. Intratumoral and intravenous administration of Nowarta110 effectively treated murine melanoma in immunodeficient and immunocompetent mice. The Nowarta110 antitumoral efficacy was more pronounced in immunocompetent mice treated intravenously than immunodeficient mice. Clinical studies to examine the efficacy of Nowarta110 in human melanoma and skin cancers are warranted.

The emerging role of photodynamic therapy in the treatment of cutaneous infections.

Cutaneous infections pose ongoing challenges to standard treatments due to resistance and limited efficacy. Photodynamic therapy (PDT) emerges as a promising supplement or an alternative to address complicated cases. In this review, we comprehensively review PDT's safety and efficacy in treating cutaneous infections. A PubMed systematic review with search terms for PDT treatment, hair, skin, and nail infections. There were a total of 43 studies on the use of PDT in cutaneous infections which discussed the treatment of viral (N.=20), bacterial (N.=11), fungal (N.=9), and protozoal (N.=3) infections. There is evidence for using PDT, mostly 5-aminolevulinic acid (5-ALA) and methyl aminolevulinate (MAL), in the treatment of cutaneous infections. Most evidence for viral infections involved treatment with 5-ALA PDT in condyloma acuminatum (CoAc), verruca vulgaris, and molluscum contagiosum. In bacterial infections, 5-ALA and MB PDT have been used to achieve complete remission in refractory Pseudomonas and atypical mycobacteria infections without recurrence. In onychomycosis, MAL PDT achieved a 40.9% cure rate and MB PDT showed a 77.8-100% cure rate with no reports of recurrence. Parasitic infections, such as leishmaniasis have also been successfully treated with both 5-ALA and MAL PDT. PDT is a promising treatment option for cutaneous infections, with growing evidence for its utility in treating cutaneous bacterial, viral, fungal, and parasitic infections, particularly those that fail standard treatments. Side effects were mostly limited to localized pain with good outcomes and low recurrence rates.

Local Hyperthermia for Warts Treatment.

Warts, benign epidermal proliferations, are a direct result of human papillomavirus (HPV) infection, specifically targeting the keratinocytes within the stratum corneum of the skin. The development of warts is the most common clinical manifestation of HPV, with plantar warts, condylomata acuminata, and common warts being the most frequently observed types. These growths can be unsightly and sometimes painful, affecting the quality of life for those afflicted. Although various treatments are available, ranging from topical medications to surgical procedures, the quest for a treatment that is both safe and effective while minimizing invasiveness continues. This is particularly crucial for populations with heightened risk factors, such as immuno-compromised individuals. In the clinical need for minimally invasive treatments, local hyperthermia has emerged as a promising therapeutic strategy for wart management. As demonstrated in various studies, local hyperthermia is effective as a standalone treatment, offering a valuable alternative for patients seeking less intrusive therapeutic options.

Pediatric genital warts successfully treated with photodynamic therapy

Genital warts (GWs) are the most common sexually transmitted infections worldwide, caused by the human papillomavirus (HPV). In adults, the primary mode of transmission is through sexual contact, whereas in children it can occur through skin-to-skin or skin-to-mucosa contact and be sexual or non-sexual. The increasing prevalence of GWs in children has renewed the interest in therapeutic management which still presents a unique challenge, being influenced by many variables including size, quantity, and location of warts, as well as the presence of comorbidities. Photodynamic therapy (PDT) has already shown encouraging results in treating viral warts in adult patients, but its use is still not standardized in the pediatric population. On this topic, we report the case of an otherwise healthy 5-year-old child affected by GWs, successfully treated with three sessions of PDT with 10% 5-aminolaevulinic acid (ALA), at one-month intervals. Our case is paradigmatic of the potentiality of PDT to treat difficult lesions in a pediatric setting.

Application of Photodynamic Therapy with 5-Aminolevulinic Acid and Fractional CO2 Laser for the Management of Recalcitrant Plantar Warts

SignificancePlantar warts, benign lesions on the soles of the feet, are caused by the human papillomavirus (HPV) infecting keratinocytes. Complete eradication of these warts is challenging, often leading to recurrences. This study evaluates the combined clinical efficacy of topical 5-aminolevulinic acid (5-ALA) photodynamic therapy (PDT) and fractional carbon dioxide (CO2) laser treatment for recalcitrant plantar warts. ApproachData from 10 patients with recalcitrant plantar warts were analyzed. Initially, thickened hyperkeratotic tissue was removed using a super-pulsed CO2 laser. This was followed by fractional laser application, after which a 20% 5-ALA cream was applied occlusively for 4 hours. Patients then received He-Ne laser irradiation for 30 minutes at an energy density of 100 mW/cm², with treatments spaced 4 weeks apart. ResultsThe study included 10 participants aged 24 to 53 years (mean age: 33.4 ± 8.09 years). In total, 40 lesions were treated across 1 to 9 PDT sessions, with an average of 5.2 ± 2.86 sessions per patient. Complete clearance was achieved in 3 patients (30%), 4 patients (40%) showed an excellent response (≥80% improvement), while 2 patients had a partial response. One patient (10%) showed <50% improvement. The overall clearance rate was 70% (28 out of 40 lesions). Aside from temporary pain during the procedure and mild erythema post-treatment, one patient developed localized proliferative scarring. After a one-year follow-up, only one patient experienced recurrence. ConclusionsThe combination of 5-ALA PDT and fractional CO2 laser therapy shows promise as an effective and safe alternative for treating persistent plantar warts.

Knowledge and Awareness of Dental Students Regarding Human Papillomavirus and Oral Cancer in Saudi Arabia.

This study aimed to evaluate the knowledge and awareness of dental students and interns in Saudi Arabia regarding human papillomavirus and oral cancer using a cross-sectional web-based survey. A cross-sectional survey was undertaken to assess the knowledge of dental students and dental interns regarding oral cancer and awareness of human papillomavirus (HPV) in public and private dental schools in Saudi Arabia. The survey included 18 questions grouped into three sections. The responses were analyzed for variations between dental students and interns, among males and females, and those attending private or public colleges. The Chai-square test assessed the correlation between participants' demographic data and their knowledge/awareness of oral cancer and HPV. A total of 451 dental students and dental interns responded. The results show that dental students at private and public dental schools in Saudi Arabia are generally knowledgeable regarding knowledge of oral cancer and awareness of human papillomavirus. The dental interns exhibited significantly superior knowledge compared to the undergraduate dental students (p<0.05), particularly in the areas of identifying the most common location of oral cancer and recognizing the signs and symptoms of oral cancer (76.5% versus 65.1% correct answers). The dental interns showed a significant difference and better awareness (p<0.05) than dental students regarding HPV having a relationship with AIDS and HPV causing common warts. Dental students and interns in this study presented a good but less than optimal knowledge and awareness regarding HPV and its prevention. Improving education courses and training for dental students in Saudi Arabia is crucial for improving their knowledge and awareness regarding oral cancer and HPV infection.

Investigation of the Efficacy of Nowarta110 in the Treatment of HPV-16 and HPV-18 Oncogenically-transformed Human Cells and Cancer-implanted Animal Models.

Cervical cancer is the third leading cause of cancer-related death in women worldwide. Nearly all cases of cervical cancer are due to infection with human papillomavirus (HPV). Nowata110 has shown breakthrough therapeutic efficacy in phase II clinical study against plantar warts, with no reported side effects. This study evaluated the effectiveness of Nowarta110 in killing cultured HPV-transformed cancer cells and its anti-cancer effects in mice, using both vaginally engrafted and subcutaneously implanted animal cancer models. Nowata110 is a novel compound composed of colloidal silver and fig extract. The cytotoxic properties of Nowarta110 were evaluated on HPV-16 and HPV-18-transformed human cancer cells (ARPE-19/HPV-16 and HeLa cells, respectively). The therapeutic potential of Nowarta110 in vivo was evaluated following the engraftment of ME-180 epidermoid carcinoma cells in the mouse vagina or their subcutaneous implantation. Nowarta110 treatment was initiated when the tumor reached an approximate volume of 65 mm3 Results: Our data showed that HPV16-expressing human retinal pigmented epithelial cells are susceptible to Nowarta110-induced cell death, with a reduction in cell viability observed at 1% Nowarta110 and a complete absence of viable cells at 5% Nowarta110. In HPV18-expressing HeLa cells, Nowarta110 caused significant and rapid cell death at a dose of 5%, whereas lower doses of 1% did not produce the same effects. The results from animal studies indicated that Nowarta110 effectively induced tumor regression in both the intravaginal and subcutaneous tumor models. Nowarta110 effectively induced cell death in HPV-16 and HPV-18-transformed human cancer cells. It also effectively induced tumor regression in mouse models with intravaginally engrafted or subcutaneously implanted cancer cells. Considering the high prevalence of HPV-induced cervical dysplasia and cancer and the lack of treatment, clinical studies to promote the implementation of Nowarta110 are warranted.

Overview of the human papilloma virus: types and its treatment

The human papillomavirus (HPV) is the most prevalent sexually transmitted disease in the United States and one of the most common causes of sexually transmitted infections (STDs) globally. Warts are cutaneous and occasionally mucous lesions brought on by HPV, with 2-20% of elementary school students getting them. There are three types of warts: non-genital warts, flat warts, and plantar warts. Non-genital warts are hyperkeratotic, exophytic, dome-shaped papules or plaques commonly associated with HPV-1, 2, 4, 27, or 57. Flat warts appear as flesh-coloured, erythematous to brown, or hyperpigmented smooth papules with a flat top and a diameter of 2 to 5 mm. Plantar warts, also known as verrucae plantaris, are cutaneous lesions on the plantar aspect of the foot that result from a human papillomavirus infection of keratinocytes (HPV).Genital warts are transmitted through sexual contact, while autoinoculation and vertical transfer do occasionally happen. After engaging in sexual activity with an infected partner, about 70% of people experience anogenital warts. Treatment for HPV includes imiquimod cream formulations, photodynamic treatment (PDT), green tea, chemical cautery, fluorouracil cream, cryotherapy, and surgical treatment. Common warts are hyperkeratotic, exophytic, dome-shaped papules or plaques commonly found in fingers, dorsal surfaces of hands, knees, or elbows. Flat warts are flesh-coloured, erythematous to brown, or hyperpigmented smooth papules with a flat top and a diameter of 2 to 5 mm. Plantar warts are unique in their location and appearance, primarily affecting high-pressure locations on the palms and soles and are uniquely linked to HPV type 1.

Effects of the COVID-19 pandemic on inpatient dermatosurgery in Germany : Retrospective evaluation of the surgical cases from nine dermatology clinics

Currently, only little data is available on the impact of the COVID-19 pandemic on inpatient dermatosurgical care in German dermatological clinics. Aretrospective analysis of all dermatosurgical cases that were treated in inpatient setting in nine German dermatological clinics in four federal states in 2019, 2020 and 2021 was performed. The diagnoses were recorded using the ICD-10codes. In addition, demographic data such as age, gender and the length of inpatient stay were analysed. In 2019, 2020 and 2021, a total of 10,739, 9185 and 9828 dermatosurgical inpatients were treated respectively. Thus, the reduction of inpatient dermatosurgical cases was 14.5% in 2020 and 8.5% in 2021 compared to 2019. Inpatient surgical treatment of melanoma decreased by 10.1% of cases in 2020. This decrease was only 1.4% in 2021 compared to 2019. The number of inpatient surgeries performed for benign lesions such as melanocytic nevi or viral warts reduced sharply in both pandemic years. Our data show for the first time how inpatient care for the entire spectrum of dermatosurgical diseases developed during the COVID-19 pandemic in Germany. After the initial marked decline in inpatient dermatosurgical cases in 2020, there was less difference in 2021 compared to 2019. This trend can be interpreted as an indication that there is still astrong need for inpatient dermatosurgical care that cannot yet be met on an outpatient basis.

Conventional versus daylight photodynamic therapy for recalcitrant hand warts: Efficacy, safety and recurrence

BackgroundAcral warts appear as skin-colored, verrucous, hyperkeratotic papules most located on the dorsal hands, distal fingers, subungual skin, and feet. Conventional photodynamic therapy (C-PDT) has shown a good efficacy and safety profile in patients with viral warts, in both adults and children, with a good cure rate and excellent cosmetic results in front of few and light side effects. The efficacy of daylight photodynamic therapy (DL-PDT) has not yet been evaluated. Objectivesto investigate and assess the short- and long-term efficacy of PDT using 10 % aminolevulinic acid (ALA) in the treatment of multiple verrucae vulgaris of the hands. The second endpoint was to compare the efficacy and safety of C-PDT versus DL-PDT. Materials and methods68 patients (38 males and 30 females) aged between 6 and 80 years, affected by hand warts, were divided into two arms: group A was treated with C-PDT, and group B was treated with DL-PDT. Patients underwent treatments three times at 1-month intervals. The response was assessed 3 months after the last session (W24) and 1 year after the last session (W52) and scored as excellent (75–100 % reduction of total wart count), partial (74−25 % reduction), and none (< 25 % reduction or no response). Any adverse events occurring during or after ALA application or irradiation as well as pain intensity were recorded at each visit. Results48 patients (70.6 %) achieved excellent response at W24, while 6 patients (8.8 %) had a partial response and 14 (20.6 %) were resistant to treatment. Patients treated with DL-PDT were less likely to have an excellent response (66.7 %) than patients treated with C-PDT (73.7 %), although not statistically significant. Among patients with excellent or partial response (n=54), 37 % (n=20) had warts relapse at W52. Both treatment modalities were well tolerated, with transient pain as the main side effects. ConclusionPDT is effective in the treatment of verrucae vulgaris of the hands. An overall response rate of 70.6 % of excellent response was achieved. While C-PDT showed a trend towards better outcomes, DL-PDT offered a more patient-friendly approach, particularly in terms of comfort and compliance.

Detection of human papillomavirus in plantar warts and its impact on outcome.

Cutaneous warts are caused by human papillomavirus (HPV) infection. Distinguishing plantar warts from clavus and tylosis can be difficult. A less-invasive method of examining these lesions is necessary. Previously, we collected data on 90 patients with warts and related diseases to explore differentiation methods using HPV typing of tissue from the wart surface. In that study, 21 patients were diagnosed as cases with plantar warts, however, 10 of those 21 cases showed HPV-negative by polymerase chain reaction analysis, causing some ambiguity, thus their outcomes should be confirmed. To assess the role of HPV typing in clinical practice, we followed up these 21 cases (11 HPV-positive and 10 HPV-negative) and analyzed their outcomes. The HPV-positive group included HPV1a (one case), HPV27 (four cases), HPV57 (three cases), and HPV65 (three cases). The median age of the 21 patients was 43 years, that of the 11 HPV-positive cases was 37 years, and that of the 10 HPV-negative cases was 44 years. The sex ratios (male:female) of the HPV-positive and HPV-negative groups were 6:5 and 2:8, respectively. All 21 patients were treated with liquid nitrogen after surface keratin removal, concomitant with salicylic acid topical plaster or oral administration of Yokuinin. The longest follow-up period was 548 days. Kaplan-Meier analysis was performed to assess the healing rate according to HPV-positivity. The healing rate in HPV-positive cases was significantly higher than in HPV-negative cases (P = 0.001). Although the sample size was small, the results suggest HPV typing using non-invasive surface materials facilitates accurate diagnosis and prevents prolonged treatment of plantar warts.

Clinical cases of verruciform epidermodysplasia of Lewandovski—Luts

Data from the medical literature and own observations of veruciform epidermodysplasia of Lewandovski — Luts (VEDLL) indicate that there are many issues that need to be resolved or clarified. They relate, in particular, to carrying out genetic research — in order to prove the phenomenon and regularities of heredity of dermatosis. The detection of a benign neoplastic formation in one of our patients — esophageal leiomyoma — obliges doctors to carefully examine patients with VEDLL, even without complaints about disorders of one or another body system. Does such a case not suggest the possibility of neoplastic transformation of a benign nature and not only from the side of the skin (papillomas and warts)? Can HPV for VEDLL cause, in addition to skin carcinoma, the occurrence of internal organ tumors? An important task of dermatologists is the early detection of patients among children, who often have common forms of wart-like efflorescences. It can be assumed that in some patients, the disease is latent for some time and manifests itself only under the influence of adverse factors (inadequate insolation, stress, etc.). The issues of VEDLL require practicing dermatovenereologists not only to conduct clinical and differential diagnosis of wart-like dermatoses but also to carry out laboratory tests to identify dermatosis (biopsy, cytology, PCR), which will allow for more frequent detection of VDLL. Since the rarity of VEDLL does not contribute to the accumulation of a sufficient amount of results on the detection of pathogenetic factors of dermatosis, particularly immunological ones, the treatment problem remains relevant. It is necessary to conduct permanent monitoring of the development of VEDLL to identify early signs of neoplastic transformation and determine predictors, that is, prognostic parameters, and introduce methods for their determination.

Needling Technique (with or without Cryotherapy) versus Cryotherapy Alone in Treatment of Multiple Plantar Warts

Abstract Background Plantar warts are common benign tumors caused by human papilloma virus (HPV) infection of the epidermal cells with an estimated annual incidence of 14%. Needling, a novel therapeutic approach, stimulates the immune system resulting in clearance of even untreated lesions, in several patients. Introduction of human papilloma virus infected keratinocytes into the subcutaneous layer may facilitate a desired immune response. On the other hand, Cryotherapy, an inexpensive and simple traditional provider administered procedure using liquid nitrogen in a spray or cryoprobe, is frequently used in many countries as a first line of treatment of plantar warts. Objective To evaluate the efficacy and safety of immunotherapeutic modality (needling) versus locally destructive modality (cryotherapy), as well as combination of both immunotherapeutic modality and locally destructive modality (cryotherapy) in treatment of multiple plantar warts. Methods This is a randomized therapeutical prospective clinical study included 60 patients aged from 19 to 55 years with planter warts (&amp;gt;2) who haven't received treatment for the condition within the previous month, divided into 3 groups, 20 patients per group, one group subjected to needling procedure, another group subjected to cryotherapy and the third group subjected to a combination treatment of both needling and cryotherapy. Results Regarding patients' satisfaction, there was a statstical significant difference between the 3 studied groups as regard patients' satisfaction (median/range), being higher in cryotherapy and combined treatment groups than in needling group. This is the rapid effect of cryotherapy in warts treatment which shows higher scores in the 8th week. Also, not all patients are satisfied with needling since it is not commonly used as cryotherapy, which makes patients question its efficacy especially when used alone. As it is a painful procedure that has to be performed with local anesthetic which consumes a lot of time. Regarding reported side effects of our study, patients of needling group experienced pain, mild bleeding and mild infection. While patients of cryotherapy group experienced pain, blistering, infection and high recurrence rates. Patients of the combination treatment group experienced pain, mild bleeding and blistering. Conclusion Combining cryotherapy (locally destructive method) and needling (immunotherapeutic method) provides promising results as it combines benefits of cryotherapy, being rapid, safe and shows rapid response together with benefits of needling, being an immuno-stimulant that provides effective, long lasting, minimally invasive, low-cost treatment with excellent safety profile and low recurrence rates for treatment of plantar warts.

Hypericin Mediated Photodynamic Therapy (HY-PDT) versus Methylene Blue Mediated Photodynamic Therapy (MB-PDT) in Treatment of Common Warts: A Comparative Study

Abstract Background Many therapeutic modalities are available for the treatment of warts, but no single therapy is universally effective. Warts can resolve, recur, shrink, or grow despite therapy. Aim of the Study to compare between the efficacy and safety of topical hypericin (HY)-mediated photodynamic therapy (PDT) and methylene blue (MB)-mediated PDT in the treatment of common warts. Patients and Methods The study included 40 patients subdivided into two groups (20 patients each). Group one (MB group) patients were treated with topical MB/IPL PDT. Group two (Hypericin group) patients were treated with topical HY/IPL PDT. Patients were assessed using digital photography and dermoscopic examinations. Results MB-mediated PDT group showed that there was significant difference regarding the decrease of size of warts before versus after MB-mediated PDT. HY- mediated PDT group showed that there was a significant difference regarding the decrease of size and number of warts before versus after HY-mediated PDT. There was better response with HY-mediated PDT compared to MB-mediated PDT without statistical significance. Conclusion Both HY and MB-mediated PDT are effective in clearing common warts. Hypericin is a promising photosensitizer alternative that has a potential efficacy for clearing wart by PDT.

Variable clinical presentation of hypomorphic DCLRE1C deficiency from childhood to adulthood.

In this study, we aimed to report long-term follow-up of our pediatric and adult patients with DCLRE1C (DNA cross-link repair 1C) hypomorphic mutation who were diagnosed leaky severe combined immunodeficiency (SCID). Eighteen patients (13 children and five adults), aged between 6 and 29 years were included. Clinical and immunological features, including immunoglobulin levels, T and B cells, natural killer cell subsets, regulator T (Treg) cell ratios/markers, and cytokines, were assessed before and after hematopoietic stem cell transplantation (HSCT) and compared with healthy controls. Recurrent infections (78%) and skin manifestations (61%) such as granulomatous skin lesions, warts, and vitiligo were the most common clinical findings. Autoimmune diseases were observed in 33% and malignancy in 17%. Most patients had low serum IgA and B- and T-cell lymphopenia at the first admission. Recent thymic emigrants (RTE), Tnaive, Bnaive, CD56dimCD16+ cell ratios were significantly lower in the patients than in control; however, follicular helper T TFH and Th1 [interferon gamma (IFN-γ)] cell ratios were significantly higher than the control. Although, Treg ratio and its functional receptors tend to be high but not significant. Eleven patients (61.1%) were treated with HSCT. Median follow-up times of transplant patients was 56 (9-67) months. Patients with hypomorphic DCLRE1C mutations may present with variable clinical and laboratory findings at different ages. Our study showed a helper T (Th)1-dominant immune response before and after HSCT. Increased IFN-γ and TFH cells ratio could be a reason of chronic inflammation and autoimmunity developing before and after HSCT. Long-term follow-up of these patients after HSCT will help to better understand the disease and its pathophysiology.

Epidemiological Characteristics of Patients with Plantar Warts: a Single-center Retrospective Study

Background: Plantar wart is a common dermatologic disease encountered in outpatient clinics. Clinical trials for the treatment of plantar warts have been conducted, but only a few studies have focused on the epidemiological factors of plantar warts. Objective: This study aims to analyze the epidemiological factors for plantar warts in Korean individuals at a single institution. Methods: We retrospectively reviewed the electronic medical records of patients with plantar warts at Chosun University Hospital from January 2019 to December 2022. Results: A total of 176 patients were included in this retrospective study. Plantar warts are more common in younger ages, and men tend to have higher rates of plantar warts than women (M:F = 3:1). The patients showed a higher incidence of plantar warts during winter (29.0%), of which 74.4% were urban residents. 6.3% of patients had warts after trauma. Plantar warts were also observed in 66 of the 504 household members of the patients. The most common locations of wart lesions were in the forefoot (73.3%), followed by the toes (60.8%), midfoot (22.2%), and heel (18.2%). Moreover, the location of the lesions was almost equal, most often on the right side (34.7%), followed by the bilateral (33.5%) and left sides (31.8%). Conclusion: This study offers valuable information about the epidemiological factors of plantar warts in South Korea. These contents will be used for lifestyle education to prevent the recurrence of plantar warts.

Congenital ichthyosis is associated with cutaneous infections in a case-control study of 2260 patients.

Evidence of congenital icthyosis association with cutaneous infections is limited to case reports. We conducted a nested case-control study assessing congenital ichthyosis associations with cutaneous infections using a large national database. Congenital ichthyosis patients vs. controls had higher odds of onychomycosis, tinea corporis, verruca vulgaris, and tinea pedis.

A pilot study on the efficacy of 10600 nm carbon dioxide laser ablation in treatment of eyelid margin lesions.

Eyelid margin lesions cause discomfort by impeding both central and peripheral vision, depending on their position on the eyelids, thus hindering everyday routines. However, surgical excision, radiofrequency, electrocautery, and cryosurgery are employed for treatment, although they are complicated and have functional limitations. Carbon dioxide (CO2) lasers were used to assess the efficacy, safety, and patient satisfaction with CO2 laser ablation in managing eyelid margin lesions. This is a pilot study of patients with eyelid margin lesions presented to a private clinic in urban Gujarat between June 2020 and June 2023. All patients were treated with a 10600 nm CO2 laser with a power of 1-2 W in continuous mode. The eyelid lesions were classified into three categories based on their size: Small (1-3 mm), medium (4-6 mm), and large (7-10 mm). The clinical response was assessed by the treating physician at week 1 and week 4, and categorized as excellent (complete clearance of lesion), moderate (>50%), or poor (<50%). Patients were asked to rate their level of satisfaction on a three-point scale at the end of the follow-up period: Dissatisfied, somewhat satisfied, or very satisfied. Ten patients of all females with six of them having compound melanocytic nevi, two of them each had cystic hidradenoma, and one each had cyst of zeis and verruca vulgaris. Six of them had small lesions, two had medium, and two had large lesions. The clinical response grading of physicians at both 1 week and 4 weeks was excellent, and the patient satisfaction questionnaire yielded excellent outcomes. The ablative CO2 laser is an excellent device used for the treatment of eyelid margin lesions, particularly when performed by an expert and skilled dermatologist. The application of this treatment approach has proven to be very beneficial and shows excellent results in terms of both the esthetic appearance and structural function of the eyelids.
