Demographic and Clinical Features and Factors Affecting the Quality of Life of Patients With Hidradenitis Suppurativa: A Cross-sectional Study.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder with well-known adverse effects on quality of life (QoL). Improving patients' QoL has become an important objective of treatment. OBJECTIVE: The purpose of this study was to evaluate the demographic and clinical characteristics and factors affecting the QoL of patients with HS. MATERIALS AND METHODS: One hundred seventy-six patients with HS aged between 18 and 65 years were included in the study. The patients' demographic and clinical characteristics, treatments, and comorbidities were recorded. The disease stage was determined based on the Hurley staging system. The Dermatology Life Quality Index (DLQI) was used to evaluate QoL. RESULTS: Mean DLQI scores were significantly higher in patients with advanced Hurley stages, lesions in the gluteal region and legs, and with more than 2 affected areas ( p < .001). Correlations between patient-reported treatment outcomes and clinical characteristics of the patients were assessed. Findings of this study indicate the existence of a potential "window of opportunity" for laser epilation and wide local surgical excision, similar to anti-tumor necrosis factor therapy. CONCLUSION: Timely and appropriate treatment can only be provided for patients with HS by evaluating objective disease severity measures and subjective patient data in combination.

Efficacy of Long-Pulsed Nd:YAG Laser for Classic Kaposi's Sarcoma: A Dermoscopic Study.

INTRODUCTION: Classic Kaposi's sarcoma (CKS) is a chronic and indolent skin tumor. Because CKS has a low mortality rate but can have a significant impact on quality of life, it is important to choose safe, long-term treatments with minimal side effects. OBJECTIVES: The aim was to assess the efficacy of long-pulsed Nd:YAG laser therapy in treating CKS based on clinical and dermoscopic observations. METHODS: Forty-two nodular lesions from three CKS patients (stage 4) were treated using a long-pulsed Nd:YAG laser with a spot size ranging from 3 to 7 mm, a fluence of 200-250 j/cm2, and a pulse duration lasting between 10 and 20 milliseconds in one or two sessions. Patients were photographed clinically and dermoscopically before the procedure, immediately after the procedure, and at 1, 6, and 12 months after the procedure. RESULTS: All participants displayed significant clinical and dermoscopic improvements, and all lesions healed within 2-3 weeks, resulting in only minor atrophic scars. No instance of recurrence was found among any of the patients during the 1-year follow-up. CONCLUSIONS: Nd:YAG laser therapy may prove to be an effective therapeutic alternative for both early and advanced-stage CKS, specifically in instances of stubborn cutaneous lesions or patients receiving systemic therapy. The treatment results in quick improvement, typically within 2-3 weeks, and is well tolerated. Nd:YAG laser therapy could provide potential benefits for HIV-positive patients as it is free from immunosuppression, easy to apply to recurring lesions, and demonstrates overall effectiveness and safety.

Comparison of phenotypic features in patients with single vs multiple primary cutaneous melanomas: a prospective single-center study.

BACKGROUND: There is sparse data regarding total body nevus count (TBNC), nevus count in specific locations, phenotypic factors, anthropometric indices, sunburn, and the relation to multiple primary cutaneous melanomas (MPCM) development. We aim to compare these variables in a cohort of patients diagnosed with single primary melanoma (SPM) and MPCM with histologic diagnoses of melanoma in situ, superficial spreading, and nodular melanoma in our clinic. METHODS: Prospective observational studies for the evaluation of nevus counts in biopsy-proven melanoma patients from 2017 to 2020 at Ankara University were conducted. Age, gender, family history of melanoma, increased sun exposure, nonmelanoma skin cancers (NMSC), height, sunburn history, TBNC, and nevi count in specific anatomical locations were evaluated by multivariate logistic regression analysis. RESULTS: A total number of 156 patients consisting of 22 MPCM and 134 SPM were included. Mean TBNC for SPM vs MPCM patients were 96.87 (SD ± 124.71) vs 247.00 (SD ± 261.58), respectively (P < 0.0001). TBNC was correlated to the left arm, trunk, lower extremity, and head and neck nevus counts but not with the right arm nevus count. Multiple regression analysis showed that having more than 10 nevi on the head and neck area is associated with MPCM (OR, 3.882 [95% CI, 1.084-13.899]). TBNC and nevus count in specific locations were found to be significantly higher in MPCM. CONCLUSION: The risk of MPCM was associated with having ≥10 nevi on the head and neck.

Superficial Acral Fibromyxoma.

Superficial acral fibromyxoma is a rare, benign, slow-growing, soft-tissue tumor commonly located in the acral regions, with a predilection for the great toe, developing from the nail unit. Because of its nonspecific features and rarity, clinical diagnosis is difficult. In this article, we present a case of superficial acral fibromyxoma located in the nail unit with new dermatoscopic and radiologic findings that have not been previously reported in the literature.

Basosquamous carcinoma and melanoma collision tumor in a child with xeroderma pigmentosum.

Xeroderma pigmentosum (XP) is a rare autosomal recessive genodermatosis associated with hypersensitivity to ultraviolet radiation (UVR), being due to defects involving the nucleotide excision repair pathway. Patients with XP are prone to develop multiple cutaneous neoplasms including non-melanoma skin cancers and melanoma. Collision tumors in patients with XP have been reported in the literature including the following lesions, actinic keratosis, basal cell carcinoma, squamous cell carcinoma, and in situ melanoma. Herein, we present a rare collision tumor composed of melanoma and basosquamous carcinoma in a 13-year-old XP patient and describe the dermoscopic features.

Clinical and Sociodemographic Characteristics of Ingrown Nails in Children.

BACKGROUND: Ingrown nail is a condition frequently seen in children and adolescents, the pain from which can affect their daily living activities and school performances. The purpose of this study was to determine the clinical and sociodemographic characteristics of ingrown nails in children. METHODS: The clinical and sociodemographic characteristics of patients aged 0 to 18 years presenting with ingrown nail were evaluated retrospectively from clinic records. RESULTS: Sixty-two patients aged 3 to 18 years (mean age, 15 years; male to female ratio, 1.06) were enrolled. A total of 175 ingrown nails were evaluated (all of them were in the halluces, 54.3% of them were on the lateral margin). A positive family history of ingrown nail was present in 15.7%. High prevalences of incorrect nail cutting (72.1%), trauma (36.1%), poorly fitting shoes (29%), hyperhidrosis (12.9%), obesity (9.7%), and accompanying nail disorders (9.7%) were determined among the patients. CONCLUSIONS: This study revealed the clinical and sociodemographic characteristics of ingrown nails in children. These data will be useful in preventing the occurrence of ingrown nail by revealing and then eliminating predisposing factors.

Clinical and Sociodemographic Characteristics of Patients with Ingrown Nails.

BACKGROUND: Ingrown nail is a common health problem that significantly affects daily life due to its painful nature. The purpose of this study was to reveal the clinical and sociodemographic characteristics of ingrown nails. METHODS: The clinical and sociodemographic characteristics of patients older than 18 years presenting with ingrown nail were investigated. RESULTS: Two hundred six patients aged 18 to 77 years (mean age, 39 years; female to male ratio, 1.45) were included in the study. A total of 729 lesions were evaluated (718 ingrown nails were on the feet and 11 were on the fingers). A family history of ingrown nail was present in 7.6% of the participants. Of the 206 patients, 26.7% were treated with surgical methods for ingrown nails previously and experienced recurrence. Ingrown toenails were in the hallux in 81.3% of patients, and 52% were on the lateral margin. Incorrect nail-cutting habits (73.5%), poorly fitting shoes (46.2%), excessive angulation of the nail plate (35.8%), obesity (34.1%), trauma to the feet (24.3%), pregnancy (23.8% of women), hyperhidrosis (16.8%), and lateral deviation of the nail plate (9.9%) were closely associated with ingrown nails. CONCLUSIONS: This study revealed the clinical and sociodemographic characteristics of ingrown nails. The study data will be useful in preventing the development of ingrown nail and recurrences after treatment by identifying and then eliminating conditions establishing a predisposition to it.

Hidradenitis suppurativa: Clinical characteristics and determinants of treatment efficacy.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder that causes a significant decline in quality of life. There are numerous treatment options; however, real-life data on the efficacy of these treatments is limited. This study was performed in two centers to describe clinical characteristics and assess treatment outcome in a cohort of 139 patients with HS. Data on demographic and clinical characteristics, Hurley stage and comorbidities were collected from patient charts and evaluated retrospectively. Treatment response was measured with HS clinical response index (HISCR). Mean body mass index was 27.8±4.88. Inflammatory comorbidities were present in 23%. Among first-line drugs systemic doxycycline resulted in 60% HISCR followed by rifampicin-clindamycin combination (46.4%). Isotretinoin had the lowest HISCR (30.7%) in this group. For second-line therapies, all acitretin treated patients achieved response and patients treated with tumor necrosis factor alpha (TNF-α) inhibitors had the highest HISCR. Currently recommended first-line therapies have moderate efficacy in HS. Acitretin appears to be a reasonable alternative for the highly effective TNF-α inhibitors in patients with severe and resistant HS. Overall, these results support that excessive inflammatory response play an important role in pathogenesis of HS.

Lichen sclerosus associated with Nd:YAG laser therapy.

Laser is the most efficient and popular method in hair removal. The most common side effects of laser assisted hair removal are pain, erythema, edema, hypopigmentation, hyperpigmentation, blistering, crusting, erosions, purpura, folliculitis, and scar formation ( 1 ). Herein, for the first time we describe a case of lichen sclerosus (LS) following hair removal with long pulsed 1064 nm Nd:YAG laser therapy.

Risk Factors and Frequency of Ingrown Nails in Adult Diabetic Patients.

The present study evaluated the properties of nails, frequency of ingrown nails in patients with type 2 diabetes mellitus (DM), risk factors for developing ingrown nails, and effect of diabetic polyneuropathy and vasculopathy on the development and outcome of ingrown nails. Our 6-month epidemiologic prospective study included 300 patients with type 2 DM attending a DM outpatient clinic for routine examinations. The general characteristics and foot changes of the study population were investigated. Diabetic polyneuropathy and vasculopathy were evaluated using a biothesiometer, monofilament tests, and arterial Doppler ultrasonography. The frequency of ingrown nails was 13.6%. Multivariate analysis with logistic regression showed that body mass index (odds ratio [OR] 1.077, 95% confidence interval [CI] 1.007 to 1.15; p = .03), previous trauma (OR 2.828, 95% CI 1.017 to 7,867, p = .042), a weak dorsalis pedis pulse (OR 2.72, 95% CI 1.17 to 6.30, p = .02), trimming type (OR 2.3, 95 CI 1.06 to 4.98), p = .35), onychogryphosis (OR 9.036, 95% CI 2.34 to 34.87, p = .001), and subungual hyperkeratosis (OR 4.3, 95% CI 1.99 to 9.3, p = .001) were predictive variables for ingrown nails in our population. The incidence of onychomycosis was significantly greater in patients with ingrown nails (p = .032) than in patients without ingrown nails. The nail curvature ratio was greater in the patients with ingrown nails than in the group with normal nails. Arterial Doppler ultrasound examinations showed peripheral arterial disease in 19 patients (46.9%) with ingrown nails. The prevalence of ingrown nails was greater in the patients with DM than in the healthy population. Our results indicate that nail type, nail morphology, and diabetic vasculopathy affect the formation and evolution of ingrown nails.

Long-Term Follow-Up Results of Topical Imiquimod Treatment in Basal Cell Carcinoma.

BACKGROUND: Imiquimod 5% topical cream is approved for treatment of superficial basal cell carcinoma (BCC). Data on the long-term efficacy and usage in other BCC subtypes are scarce. OBJECTIVE: Evaluation of long-term safety and efficacy of topical imiquimod treatment in various BCC subtypes and locations, with individualized treatment duration. MATERIALS AND METHODS: Histopathologically confirmed BCCs treated solely with topical imiquimod were identified retrospectively and included in this study. Clinical and histopathologic tumor clearances were the primary end point. After treatment was concluded, patients were examined every 3 to 6 months. RESULTS: In total, 24 BCC samples from 22 patients (F:M = 9:13; mean age: 73.5 years, SD: 10.767) were evaluated. The majority of the lesions were located in the head and neck area (83%). Mean treatment duration until complete clearance was 15.7 ± 6.9 weeks (6-28 weeks). Imiquimod was discontinued in 3 lesions, due to either clinically or histopathologically insufficient response. During follow-up, 2 lesions recurred, at 42 and 50 months after treatment. During a mean follow-up time of 72.7 (SD = 9) months, 79.1% of the lesions were cured without local recurrence. CONCLUSION: Although imiquimod is only approved for superficial BCC, treatment success was high among the study patients with various histological subtypes, with good long-term cosmetic results.

Long-term results of rituximab-intravenous immunoglobulin combination therapy in patients with epidermolysis bullosa acquisita resistant to conventional therapy.

BACKGROUND: Epidermolysis bullosa acquisita (EBA) is a rare subepidermal bullous disease. Long-term remission in this disease is difficult using current treatments, unlike that in patients with other autoimmune bullous diseases. OBJECTIVE: We retrospectively evaluated the effectiveness and side effects of rituximab-intravenous immunoglobulin (IVIg) combination treatment in five patients with EBA resistant to conventional treatment. PATIENTS AND METHODS: Rituximab (375 mg/m2) was administered for four consecutive weeks to four patients, and their treatment continued with IVIg at a dose of 2 g/kg/month. One patient received two cycles of rituximab for three consecutive weeks, IVIg in the fourth week, followed by monthly IVIg administrations as in the other patients. RESULTS: The total number of IVIg therapy cycles ranged from 10 to 26 (mean 19.4). Mean skin involvement, mucosal involvement, and disease severity scores decreased after a mean follow-up of 22.6 months (range, 10-28 months). In an analysis performed during months 24-28, the number of CD19-positive B cells was found to be below the normal reference range in four patients. LIMITATIONS: This was a retrospective study with a limited number of patients. CONCLUSION: Rituximab-IVIg combination treatment seems to be effective and safe for treating patients with EBA resistant to conventional treatments.

Development of poorly differentiated invasive squamous cell carcinoma in giant Bowen's disease: a case report with dermatoscopy.

Bowen's disease (BD) is an in situ form of squamous cell carcinoma (SCC), often occurring in the chronically UV-damaged skin of elderly people. The risk of progression of BD to invasive SCC varies between 3% and 5%, and one-third of invasive tumors may metastasize. Herein we discuss the dermatoscopic findings of a case of giant Bowen's disease, which progressed to poorly differentiated invasive SCC.
