Large Language and Vision Assistant in Dermatology: A Game Changer or Just Hype?

The integration of artificial intelligence (AI) in healthcare, particularly in the field of dermatology, has experienced significant progress through the creation of advanced tools such as the Large Language and Vision Assistant (LLaVA). This comprehensive review examines whether LLaVA represents a significant breakthrough or merely a passing trend in dermatological practice. By incorporating both language and visual analysis capabilities, LLaVA aims to support enhanced diagnostic accuracy, patient engagement, and customized treatment planning, as evidenced by current research and case studies. However, its practical utility in a clinical setting remains a subject of debate. We explore the visual assistant chatbot's potential in improving diagnostic precision, especially in analyzing skin lesions and conditions that are visually complex. The tool's capacity to process and interpret dermatological images using advanced algorithms could aid clinicians in early detection and management of skin diseases. Furthermore, LLaVA's interactive nature potentially improves patient education and adherence to treatment protocols. Despite these advantages, there are noteworthy limitations and risks. The accuracy of LLaVA in handling atypical or rare dermatological cases is an area of concern. The tool's reliance on existing medical data raises questions about bias and the generalizability of its findings. Additionally, ethical considerations, such as patient data privacy and the potential for overreliance on AI in clinical decision-making, are critical issues that need addressing. This article aims to provide dermatologists with a comprehensive understanding of large language and visual assistant's capabilities and limitations. We discuss practical guidelines for its integration into research and clinical educational augmentation, ensuring that dermatologists can make informed decisions about employing this technology for the enhancement of patient care and treatment outcomes. The question remains: is LLaVA a game changer in dermatology, or is it just hype? This review endeavours to answer this, establishing a foundation for knowledgeable and efficient application of visual AI chatbots in dermatology practices.

Cutaneous Findings in Inborn Errors of Immunity: An Immunologist's Perspective.

Cutaneous manifestations are common in patients with inborn errors of immunity (IEI)/primary immunodeficiency and could be due to infections, immune dysregulation, or lymphoproliferative/malign diseases. Immunologists accept some as warning signs for underlying IEI. Herein, we include noninfectious/infectious cutaneous manifestations that we come across in rare IEI cases in our clinic and provide a comprehensive literature review. For several skin diseases, the diagnosis is challenging and differential diagnosis is necessary. Detailed disease history and examination play a vital role in reaching a diagnosis, especially if there is a potential underlying IEI. A skin biopsy is sometimes necessary, especially if we need to rule out inflammatory, infectious, lymphoproliferative, and malignant conditions. Specific and immunohistochemical stainings are particularly important when diagnosing granuloma, amyloidosis, malignancies, and infections like human herpes virus-6, human herpes virus-8, human papillomavirus, and orf. Elucidation of mechanisms of IEIs has improved our understanding of their relation to cutaneous findings. In challenging cases, the immunological evaluation may lead the approach when there is a specific primary immunodeficiency diagnosis or at least help to reduce the number of differential diagnoses. Conversely, the response to therapy may provide conclusive evidence for some conditions. This review raises awareness of concomitant lesions and expands the scope of the differential diagnosis of IEI and the spectrum of skin disease therapy by highlighting frequent forms of IEI-associated cutaneous manifestations. The manifestations given here will guide clinicians to plan for alternative use of diverse therapeutics in a multidisciplinary way for skin diseases.

A rare involvement in skin cancer: Merkel cell carcinoma with bone marrow infiltration in a kidney transplant recipient.

A 60-year-old man presented with a painless, rapidly growing, haemorrhagic pink nodule on the posterior of his thigh that had developed 1 month previously. He had a diagnosis of IgA nephropathy and had received a renal allograft 7 years before. An excisional biopsy was performed and the diagnosis of Merkel cell carcinoma (MCC) was made. No distant metastases was detected. 10 months after first presentation, due to the development of acute pancytopenia and concomitant FDG PET/CT findings compatible with disease progression, bone marrow biopsy was performed which revealed metastasis of MCC. Dermatologists and oncologists should be aware that MCC could potentially involve the bone marrow in organ transplant recipients. In the follow-up period, a complete blood count should be carried out; FDG PET/CT can be obtained to follow up the metabolic status of the disease and bone marrow biopsy should be performed if necessary.

Thermo-SPT: A new skin prick test evaluation framework based on low-cost, portable smartphone thermography.

BACKGROUND: Although the skin prick test (SPT) is a reliable procedure to confirm IgE-dependent allergic sensitization in patients, the interpretation of the test is still performed manually, resulting in an error-prone procedure for the diagnosis of allergic diseases. OBJECTIVE: To design and implement an innovative SPT evaluation framework using a low-cost, portable smartphone thermography, named Thermo-SPT, to significantly improve the accuracy and reliability of SPT outcomes. METHODS: Thermographical images were captured every 60 s for a duration of 0 to 15 min using the FLIR One app, and then analysed with the FLIR Tool® . The definition of 'Skin Sensitization Region' area was introduced to analyse the time-lapse thermal changes in skin reactions over several time periods during the SPT. The Allergic Sensitization Index (ASI) and Min-Max Scaler Index (MMS) formulae were also developed to optimize the identification of the peak allergic response time point through the thermal assessment (TA) of allergic rhinitis patients. RESULTS: In these experimental trials, a statistically significant increase in temperature was detected from the fifth minute of TA for all tested aeroallergens (all p values < .001 ). An increase was observed in the number of false-positive cases, where patients with clinical symptoms not consistent with SPT were evaluated as positive on TA assessment, specifically for patients diagnosed with Phleum pratense and Dermatophagoides pteronyssinus. Our proposed technique, the MMS, has demonstrated improved accuracy in identifying P. pratense and D. pteronyssinus compared with other SPT evaluation metrics, specifically starting from the fifth minute. For patients diagnosed with Cat epithelium, although not statistically significant initially, an increasing trend was determined in the results at the 15 min (ΔT (T15 - T0 ), p = .07 ; ASIT15 , p < .001 ). CONCLUSIONS: This proposed SPT evaluation framework utilizing a low-cost, smartphone-based thermographical imaging technique can enhance the interpretability of allergic responses during the SPT, potentially reducing the need for extensive manual interpretation experience as standard SPTs.

Diagnostic Role of Direct Immunofluorescence Assay in Determining The Etiology of Erythroderma: Experience in a Tertiary Referral Hospital.

Introduction: Erythroderma is a life-threatening dermatologic emergency which is characterized by diffuse erythema and exfoliation affecting more than 90% of the body surface area. Most common cutaneous diseases associated with erythroderma are systemic contact dermatitis, psoriasis, drug eruption and atopic dermatitis. Clinical-pathological correlation is used to determine the underlying disease. In addition, direct immunofluorescence (DIF) may provide significant clues for etiology of erythroderma especially in the case of autoimmune bullous skin diseases (ABSDs). Objectives: In our study, we aimed to analyze the demographic data, clinical pre-diagnoses, final diagnosis, histopathological and DIF examination findings, accompanying systemic signs and laboratory abnormalities of erythrodermic patients. Methods: We conducted a retrospective study of 31 erythroderma patients in a referral hospital between 2014 and 2021. Cutaneous biopsies were taken from all patients for H&E and DIF examination. Results: Average age was 54.6 ± 23 years, 48.4% of the patients were female (N = 15) whereas 51.6 % of the patients were male (N = 16). Average time between the onset of rash and biopsy was 18.8 days. DIF analysis showed immune deposits in 19.4% (N = 6) of the patients; whereas no immune deposits were detected in 80.6% (N = 25) of the patients. The most frequent final diagnosis was adverse cutaneous drug eruption followed by ABSDs. Conclusions: Our findings suggest that DIF may be used in conjunction with clinical-pathologic and clinical findings to reveal the associated skin diseases in erythrodermic patients. Erythrodermic patients presenting with clinical findings of ABSD should be considered for DIF examination.

Impact of COVID-19 Pandemic on Hidradenitis Suppurativa Patients: a Cross-Sectional Study From Tertiary Referral Hospital.

Introduction: Hidradenitis suppurativa (HS) is a chronic, disabling skin disorder which is characterized by recurrent attacks of nodule, abscess, sinus tract formation and scarring. Oral/topical antibiotics, oral retinoids and TNF-alpha inhibitors are used for the treatment of HS. Objectives: In the present study, we aimed to determine the prevalence of coronavirus disease 2019 (COVID-19) real-time polymerase chain reaction (real-time PCR) positivity and the presence of COVID-19 related symptoms in relation to the age, gender, body mass index, disease duration, treatment used for HS, treatment duration and smoking. Methods: We conducted a comparative, cross-sectional study of 178 patients diagnosed with HS in a referral hospital. Age, gender, smoking status, body mass index, treatment modalities used for HS, the presence of COVID-19 related symptoms, history of close contact to a person with COVID-19 and COVID-19 real time-PCR results were determined by a telephone questionnaire. Results: Sixty-three patients were female, whereas 115 patients were male. During COVID-19 pandemic, 94 out of 178 patients had COVID-19 related symptoms; COVID-19 real time-PCR test was performed in 109 (61.2%) patients. Thirty (27.5%) cases tested positive for COVID-19 whereas 79 (72.5%) tested negative. Conclusions: Patients having COVID-19 related symptoms were shown to have statistically significantly higher mean age compared to the ones who did not have any symptoms (P = 0.031). No statistically significant relationship was found COVID-19 real time-PCR positivity and the type of treatment administered for HS when categorized as tumor necrosis factor-alpha inhibitor, oral retinoid, topical antibiotic and oral antibiotic group (P > 0.05).

Role of work breaks in well-being and performance: A systematic review and future research agenda.

Recovery from work is a critical component for employees' proper functioning. While research has documented the beneficial effects of after-work recovery, it has focused far less on the recovery that happens while at work in the form of work breaks. In this review, we systematically review available empirical evidence on the relationship between work breaks and well-being and performance among knowledge workers. Doing so enables us to (a) integrate studies from multiple disciplines, (b) propose a conceptual framework for categorizing work breaks, and (c) provide a future research agenda for studying the role of work breaks in employee well-being and performance. Using Cochrane's guidelines, we review observational and intervention studies (N = 83). Based on the extant research, we propose that work breaks can be described and classified in terms of five features: initiator, duration, frequency, activities, and experiences. The result of our review is an integrative model that comprehensively captures the relationship between work breaks and well-being and performance outcomes, as well as the mechanisms and boundary conditions of these relationships. We conclude by proposing avenues for the future study and practice of work breaks. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The correlation between tumor thickness and aggressive histopathological pattern in Basal cell carcinoma.

BACKGROUND: The significance of tumor thickness is not clear in the prognosis of basal cell carcinoma. We aimed to identify the relationship between the tumor thickness and aggressive histopathological growth pattern in BCC. METHODS: We retrospectively reviewed 85 primary BCCs of 82 patients. A total of 78 (91.7%) tumor slides were available for review, 7 (8.2%) missing slides in archive could not to be re-evaluated. We recorded the histological subtype, ulceration, perineural invasion, and the tumor thickness. Tumors with infiltrative, micronodular, morpheaform and basosquamous features were classified as having an aggressive growth pattern. RESULTS: The aggressive growth pattern was determined in 21 (26.9%) tumors with a mean tumor thickness of 2.19 ± 0.71 mm (range, 0.9-3.40). The non-aggressive growth pattern was detected in 57 (73%) tumors and the mean tumor thickness was 1.76 ± 0.87 mm (range 0.50-4.40 mm). There was a statistically significant difference in the mean tumor thickness between the tumors with aggressive growth pattern and non-aggressive growth pattern (p = 0.033). CONCLUSION: Tumor thickness might have positive correlation with aggressive histological pattern. Measuring and reporting tumor thickness may be a more practical way to determine the pathological risk for BCC.

Dermatology consultation requests from a university hospital's pediatric and adult emergency departments: A 5-year retrospective analysis.

BACKGROUND: Unnecessary dermatology consultation requests from emergency departments (EDs) are a common occurrence worldwide. AIM: This study aimed to analyze the demographic and clinical characteristics of patients consulted to the dermatology department for dermatologic disorders by a university hospital's pediatric ED (PED) and adult ED (AED). MATERIALS AND METHODS: The electronic medical records of 2316 dermatology consultation requests from the PED and AED during a 5-year period were retrospectively reviewed. Patient demographic and clinical characteristics, dermatological diagnoses, and time of day of dermatology consultation requests from the PED and AED were retrospectively analyzed. RESULTS: The electronic medical records of 1845 consultation requests with complete data were included in the study. There were 969 (52.5%) consultation requests from the PED and 876 (47.5%) from the AED. Mean time from onset of dermatological symptoms to ED presentation was 31.6 d. Herpes zoster infections (18.5%), adverse cutaneous drug reactions (8.1%), and urticaria with angioedema (7.9%) were the most common skin disorders resulting in consultation requests from the AED, versus non-specific viral infections (9.2%), insect bites (8.3%), and atopic dermatitis (8.2%) from the PED. In all, 11.5% of ED patients that received dermatology department consultation required hospitalization due to dermatologic disorders. CONCLUSION: As patients commonly present to EDs with non-urgent dermatological diseases, ED physicians should receive training on common dermatological diseases so as to decrease the number of unnecessary dermatology consultation requests.

The effect of COVID-19 on patients with chronic spontaneous urticaria treated with omalizumab and antihistamines: A cross-sectional, comparative study.

INTRODUCTION: Chronic spontaneous urticaria (CSU) is defined as recurrent attacks of urticaria present for more than six weeks. The monoclonal anti-immunoglobulin E antibody, omalizumab, was approved for the treatment of CSU in patients who remain refractory to H1-antihistamines. Biologic agents are shown not to increase the risk of COVID-19 infection in different studies. OBJECTIVE: In the present study, we aimed to determine the prevalance of COVID-19 infection in relation to the age, gender, presence of other comorbidities, and treatment given for CSU. METHODS: We conducted a descriptive cross-sectional study of 233 patients diagnosed with CSU in a tertiary referral hospital. Demographical data, treatment given for CSU, the presence of COVID-19-related symptoms, history of close contact to a person with COVID-19 and COVID-19 real-time polymerase chain reaction (RT-PCR) results were determined via a telephone survey and checked from medical data records. RESULTS: One hundred sixty patients were female; whereas 73 were male. The mean age was 44.76. Out of 233 patients with chronic urticaria, 125 had symptoms related to COVID-19 infection. RT-PCR testing for COVID-19 was performed in 156 patients. Of 156 patients with COVID-19 RT-PCR test, RT-PCR result was positive in 15 cases. CONCLUSIONS: No statistically significant relationship was found between COVID-19 RT-PCR positivity and the type of treatment administered for chronic urticaria when the patients are divided into omalizumab ± oral antihistamines and only oral antihistamines treatment groups (p = 0.150). Omalizumab seems to be safe in the era of COVID-19.

Age and psoriatic arthritis are important predictors of biologic agent switch in psoriasis.

BACKGROUND: The demand of biologic switching is increasing for different reasons.We aimed to define reasons for switching biologics and possible predictors for switching risk,and to estimate data on drug survival. METHODS: 115 patients treated with biologics who switched to a second, third,and/or fourth biologic were eligible for this retrospective study.Patients were divided into 2 groups as switched once,and switched twice or more.Drug survival rates were calculated using the Kaplan-Meier method. RESULTS: All patients switched at least one, 36 patients switched twice, and 9 switched thrice. First-, second-, and third-line biologics were mostly switched due to secondary lack of efficacy for skin disease.Each unit increase in age decreased the risk of having ≥2 switches 4% (p=0.038,OR:0.964,95%CI:0.93-0.998),whereas PsA increased the risk of having ≥2 switches 2.69-fold (p=0.026,OR:2.69,95%CI:1.12-6.44).There was significant difference between biologics in terms of drug survival(p=0.001).Adalimumab had a lower drug survival compared to ustekinumab(p<0.001) and secukinumab(p=0.003) in transition from second-line biologic to third-line biologic. CONCLUSION: Switching biologics was most commonly due to secondary lack of efficacy for skin disease.Lower ages and the presence of PsA were associated with a higher need for switching in long-term.Ustekinumab and secukinumab are superior to adalimumab in clinical practice in terms of drug survival of second-line biologics.

The effect of the COVID-19 pandemic on dermatology consultation requests from adult and paediatric emergency departments.

AIM: This study aimed to determine the characteristics of dermatology consultation requests from the adult and paediatric emergency departments (EDs) of a university hospital during 8 months of the COVID-19 pandemic in 2020 and to compare them with the same 8 months of 2019. MATERIALS AND METHODS: Electronic medical records of dermatology consultation requests from adult and paediatric EDs between 15 March 2019 and 15 November 2019, and between 15 March 2020 and 15 November 2020 were retrospectively reviewed. RESULTS: The study included 495 consecutive dermatology consultation requests. In total, 283 (57%) consultation requests occurred in 2019, vs 212 (43%) between in 2020 during the COVID-19 pandemic. The number of consultation requests per day was significantly lower in 2020 (0.9 ± 0.1 per day) than in 2019 (1.15 ± 0.1 per day; P = .002), and was significantly lower in March, April and May 2020, as compared with March, April, and May 2019 (P = .004, P = .001, and P = .001, respectively). The median time from onset of dermatological symptoms to ED presentation was significantly longer in 2020 than in 2019 (4 days in 2019 vs 7 days in 2020; P < .001). Dermatological emergencies in 2019 and 2020 constituted 6.7% of all emergency presentations, with no significant difference between the 2 years (7.1% of all ED presentations in 2019, vs 6.1% in 2020; P = .795). CONCLUSION: COVID-19 restrictions and fear of COVID-19 infection might have discouraged patients from presenting to EDs because of skin problems; however, the easing of COVID-19 restrictions might lead to an increase in ED presentations, including non-urgent dermatological disorders. In order to reduce unnecessary use of EDs and prevent ED overcrowding, the general public should be educated about what constitutes a dermatological emergency.

Treatment of psoriasis with biologics in the early COVID-19 pandemic: A study examining patient attitudes toward the treatment and disease course.

BACKGROUND: Since March 2020, the coronavirus disease 2019 (COVID-19) pandemic has been ongoing all around the world with a wide range of clinical course including asymptomatic cases to severe and fatal respiratory tract disease. Patients on immunosuppressive treatments were predicted to be more susceptible to COVID-19. AIMS: It was aimed to assess treatment continuity, the course of psoriasis and the course and clinical features of COVID-19 in patients treated with biological agents for psoriasis at the early initial period of COVID-19 pandemic. PATIENTS/METHODS: Patients treated with biological agents for psoriasis at our institute were contacted by phone between 1 and 10 July 2020 and fulfilled a questionnaire about their continuity to psoriasis treatments, clinical course of psoriasis, and any suspicion/diagnosis of COVID-19. RESULTS: A total of 106 patients, 41 females and 65 males, were enrolled. Mean age of the patients was 46.1 ± 12.1 years (range: 19-77). Median duration of psoriasis was 18 years (min-max: 1 month-51 years). Twenty-four patients (22.6%) were using tumor necrosis alpha inhibitors (ETA:1, IFX:19, ADA:4), whereas 82 patients (77.4%) were using interleukin (IL) 12/23 or IL-17 inhibitors (UST:48, SECU:30, IXE:4). Seventy-six patients (71.7%) continued the treatment, whereas 30 patients (28.3%) interrupted the treatment voluntarily. Twenty out of 30 patients (66.6%) who interrupted the treatment had an exacerbation of psoriasis. None of the patients were diagnosed with COVID-19 in the study period. CONCLUSION: Patients with psoriasis who received biological therapy continued their treatment at a high rate during the early period of the COVID-19 pandemic. No COVID-19 diagnosis was made among patients whether they continued or discontinued treatment. Recurrence and exacerbation of psoriasis in a significant proportion of patients who interrupted treatment and absence of COVID-19 diagnosis in each group support the importance and safety of continuity of biological treatments for psoriasis in COVID-19 era.
