Introduction: This study examined the remission probability and duration in chronic spontaneous urticaria (CSU) patients resistant to second-generation H1-antihistamines (sgAHs) undergoing omalizumab treatment.

Methods: This is a retrospective observational study of 176 adult CSU patients exhibiting a significant pruritus component (≥ 8) of the weekly urticaria activity score (UAS7) despite four daily sgAH tablets and starting omalizumab treatment with 300 mg every 4 weeks. After excluding 13 nonresponders, we analyzed 163 omalizumab responders (mean age 51.8 years, 74.4% female). The intervals between applications were increased. Discontinuation was considered for patients that remained asymptomatic on a gradually reduced dosage (to 150 mg every 12 weeks) without sgAHs.

Results: Omalizumab discontinuation was possible in 25.8% (42/163). The duration of omalizumab treatment before remission ranged from 7 to 63 months. Twenty-one patients (50.0%) maintained complete remission until the end of the observation period (September 2021) for 8 to 68 months. Of the relapsed patients, 71.4% (15/21) effectively controlled CSU with sgAHs. Six patients (28.6%; 6/21) required omalizumab reintroduction after 6 to 40 months of remission, responding favorably.

Conclusions: The study shows that a quarter of severe CSU patients achieve long-term remission. In addition, sgAHs effectively manage symptoms in a majority of relapsed cases, and those requiring omalizumab reintroduction respond favorably.

Introduction: Dermatomyositis (DM) is a group of autoimmune idiopathic inflammatory myopathies characterized by typical cutaneous signs and symptoms of muscle involvement. The diseases can be associated with cancer in the paraneoplastic syndrome, calcinosis, interstitial lung disease, other autoimmune connective tissue diseases (in overlap syndrome), and Raynaud's phenomenon.

Methods: Clinical and capillaroscopic data were gathered from 43 patients with DM. The diagnosis was based on the Bohan‒Peter and European League against Rheumatism / American College of Rheumatology (EULAR/ACR) classification criteria. In addition, nailfold capillaroscopy was performed in all patients.

Results: In our cohort, eight patients had overlap syndrome, six had paraneoplastic syndrome, eight presented with interstitial lung disease, and nine had calcinosis, two of whom also had a cancerous pathology. Raynaud's phenomenon was reported in 74% of patients. Upon nailfold capillaroscopy, 84% of patients presented giant capillaries, 81% ramified capillaries, and 70% both. The latter, notably giant ramified capillaries, could be considered specific for DM. The detection of prominent subpapillary venous plexuses was associated with pulmonary involvement. In contrast, alterations of the pericapillary spaces were associated with the severity and prognosis of DM.

Conclusions: Our results underline the usefulness of nailfold capillaroscopy in the diagnosis and prognosis of DM. Based on the results and literature data, specific nailfold capillaroscopy features should be included in DM diagnostic criteria.

Introduction: Melasma, a chronic acquired skin pigmentation disorder, is characterized by the presence of irregular-edged brown to gray-brown patches with a symmetrical distribution, primarily on sun-exposed areas such as the face. Topical hydroquinone (HQ) is the gold standard for melasma treatment but has numerous side effects. This study assesses the effectiveness of topical tranexamic acid (TA) as an alternative for melasma treatment.

Methods: In a double-blind, split-face, randomized controlled trial involving 20 subjects, the effectiveness of 3% TA versus 4% HQ cream was evaluated over 8 weeks. The modified melasma area and severity index (mMASI), melanin index, erythema index, and side effects were assessed. Subjective improvement was measured using the patient global assessment (PtGA).

Results: A significant decline in the mMASI score was observed at weeks 4 and 8 in both groups compared to baseline. There were no statistically significant differences in PtGA scores between the 3% TA group and the 4% HQ group.

Conclusions: Topical 3% TA is as effective and safe as 4% HQ for treating melasma in the Indonesian population, with potential advantages in terms of side-effect profiles.

Introduction: To date, there is no gold standard for identifying photoaging. This study investigates the correlation of photoaging profiles based on the Glogau scale and the dermoscopy photoaging scale (DPAS) in a coastal population.

Methods: An analytical cross-sectional study was conducted at Cilincing Municipal Health Center in Jakarta in October 2022. Individuals living in the coastal area, 20 years and older, with Fitzpatrick skin types III-V, and with a mean daily sun exposure of ≥ 3 hours were included. The Glogau scale and DPAS were assessed through history taking, physical examination, and dermoscopic examination. A Spearman correlation test was used to assess the correlation between the Glogau scale and DPAS.

Results: Thirty individuals with a mean age of 41.5 ± 11.5 years participated in the study. The median Glogau score was 3 (range: 2-4). The mean DPAS score was 28.5 ± 5.6. Lentigo, hypo-hyperpigmented macules, telangiectasia, deep wrinkles, and superficial wrinkles were observed in all subjects. There was a moderate positive correlation between the Glogau scale and DPAS (r = 0.536, p = 0.002).

Conclusions: The Glogau scale has a significant correlation with DPAS. DPAS can serve as a reliable, easy, practical, and fast diagnostic tool to assess the severity of aging.

Psoriasis is a chronic inflammatory disease that can often accompany human immunodeficiency virus (HIV) epidemics. Development of psoriasis in HIV patients is correlated with a decrease in CD4+ count. Significant variability in the clinical presentation of psoriasis makes it a challenging disease to diagnose. Furthermore, associated immunodeficiency complicates standard treatment with immunosuppressive and biological therapy. Articles that match the terms psoriasis and HIV were searched in MEDLINE and Embase and selected based on their relevance. Highly active antiretroviral therapy (HAART) is a medication regimen used to manage and treat HIV infection. In treating mild psoriasis in HIV-positive patients, topical agents combined with HAART are considered first-line therapy, followed by phototherapy. Second-line therapy includes oral retinoids, alone or combined. In treating challenging cases, apremilast has been used due to its lack of immunosuppressive effect. In case of progressive and refractory disease, limited data from studies suggest that immunosuppressive or biological therapy may be effective. Treatment of psoriasis in HIV patients remains a challenge, which is largely attributable to its complicated etiopathology and lack of an approved therapy option. In treating severe psoriasis, close collaboration with an infectious disease specialist is highly recommended. Further research is needed, preferably with an aim toward developing individualized therapy.

Spitz lesions represent a spectrum of melanocytic proliferations, and they include Spitz nevi, atypical Spitz tumors, and Spitz melanomas. Atypical Spitz tumors are intermediate melanocytic lesions with features between benign Spitz nevi and malignant Spitz melanomas. They often present a diagnostic challenge to pathologists and dermatologists alike because they can mimic melanoma, especially high-grade atypical Spitz tumors. Importantly, they present a relevant clinical management challenge because definite recommendations for their management and treatment have not yet been established. Here we present the case of a young patient with a high-grade atypical Spitz tumor along with the diagnostic procedure and further management. We also review potential pitfalls in the literature that should alert clinicians to the more aggressive potential of the lesion, such as some BRAF fusions.

Monkeypox virus (MPXV), originally endemic in West Africa (Clade II) and Central Africa (Clade I), has recently emerged worldwide and has reinforced the need for rapid and accurate MPXV diagnostics. This review presents and critically discusses the range of virological methods for laboratory diagnosis and characterization of MPXV as well as related lessons learned and practical experience gained from the 2022 Mpox global outbreak. Real-time PCR is currently considered the diagnostic gold standard and ensures accurate and timely confirmation of suspected Mpox cases based on suspicious skin lesions, and digital PCR improves the precision of MPXV DNA quantification. Whole genome sequencing reveals the diversity within the Clade IIb outbreak and highlights the role of microevolution in the adaptation of the virus to the human host. Continuous genomic surveillance is important for better understanding of human-to-human transmission and prevention of the emergence of variola virus-like strains. Traditional virological methods such as electron microscopy and virus isolation remain essential for comprehensive virus characterization, particularly in the context of vaccine and antiviral drug development. Despite the current challenges, serological tests detecting a range of anti-MPXV antibodies are important adjunct diagnostic and research tools for confirmation of late-presenting or asymptomatic MPXV cases, contact tracing, epidemiological studies, seroepidemiological surveys, and better understanding of the role of IgG and neutralizing antibodies in the immune response to infection and vaccination. A multidisciplinary approach combining advanced molecular techniques with traditional virological methods is important for rapid and reliable diagnosis, surveillance, and control of the outbreak.

Data on oral lesions of coronavirus disease (COVID-19) are conflicting, and there are few evidence-based data on oral lesions directly caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The aim of this case series and literature review is to determine the prevalence of oral lesions associated with COVID-19 in outpatients and identify oral manifestations that are likely associated with COVID-19. We present 15 patients that came for their first specialist examination to the Oral Medicine Outpatient Clinic, Dental Clinic, Split, Croatia between November 2020 and January 2024. Their medical and dental history was taken following CARE guidelines. The prevalence of oral lesions associated with SARS-CoV-2 was 1.42% during the 4-year follow-up period. The most common oral lesions were nonspecific erosions, stomatitis, salivary flow disorders (xerostomia, oligosialia), salivary gland diseases (sialadenitis, chronic sialadenitis), candidiasis, pigmentation, aphthae, burning mouth syndrome, and geographic and fissured tongue. The mean latency period was 25.1 days. The site most commonly affected was the tongue (61.5%). Oral lesions associated with COVID-19 occurred in middle-aged patients, with an equal distribution by sex. They presented in a mild form and did not correlate with the severity of the clinical picture of COVID-19.

Introduction: Chronic spontaneous urticaria (CSU) is characterized by persistent or recurrent pruritic lesions that last more than 6 weeks. Patients with CSU may experience sleep disturbances, particularly due to itching. Biological rhythms (chronotypes) are categorized as morningness, intermediate, and eveningness types. This study evaluates the relationship between sleep quality, chronotype, and disease severity in CSU patients.

Methods: The study included 53 CSU patients and 50 healthy controls. A sociodemographic data form was completed, and the disease severity was determined utilizing the Urticaria Activity Score over 7 days (UAS7). The Hospital Anxiety and Depression Scale (HADS), Insomnia Severity Index (ISI), and Pittsburgh Sleep Quality Index (PSQI) scales as well as the Morningness-Eveningness Scale (MEQ) were applied to the participants.

Results: The CSU group had a significantly higher body mass index (BMI) than that of the healthy control group. In terms of sleep and chronotype scales, compared to the control group, the CSU group had higher ISI scores as well as subscale scores on the PSQI subscales, with the exception of habitual sleep efficiency and total PSQI scores. There was no difference between MEQ scores. In the correlation analysis, the UAS7 and PSQI total scores were found to be correlated, whereas in the logistic regression analysis the estimated relative risk of BMI and PSQI total score for CSU was found to be 1.13 and 1.45, respectively.

Conclusions: When dealing with CSU patients, it is necessary to conduct a sleep quality assessment as part of a holistic evaluation.

A multidrug-resistant dermatophyte species recently arose in India, first described as terbinafine-resistant Trichophyton interdigitale and soon given a separate name: T. indotineae. Thanks to its treatment recalcitrance, person-to-person spread, and frequent travel, before long it was identified in many countries on all continents. We describe here the case of a boy with widespread, extremely pruritic, inflammatory dermatophytosis affecting his face, neck, trunk, and extremities, unsuccessfully treated for months with oral terbinafine and fluconazole and a range of topical antimycotics. Qualitative polymerase chain reaction of skin scrapings from his lesions identified a T. interdigitale complex fungus, highly probably T. indotineae due to conspecificity and antifungal resistance. Oral itraconazole, administered over 8 weeks, cleared the infection. Because the patient had not traveled outside the United Arab Emirates for months before the infection became obvious, it must have been acquired from a local source.
