Telemedicine in Nail Psoriasis: Validation of a New Tool to Monitor (In-Person, In-Picture, and In-Video) Nail Psoriasis Severity in Patients with Concurrent Onychophagia and Onychotillomania.
INTRODUCTION
Since during the COVID-19 pandemic nail psoriasis was evaluated exclusively with teledermatology, dermatologists started to face the difficulty in rating it concurrent with other onycopathies (i.e., onychotillomania and onychophagy). Thus, we aimed to improve the existing severity scores and verify the value in different clinical settings (i.e., in person vs. teledermatology (video or picture)).
METHODS
This multicenter prospective observational study evaluated patients with nail psoriasis and screened them for onychophagy or onychotillomania in telemedicine from May 2020 to January 2021. For therapeutic purposes patients with nail psoriasis were followed and rated with the Nijmegen-Nail psoriasis Activity Index tooL (N-NAIL) for 9 months; at the same time, N-NAIL and a new dedicated index that monitor also the changes in nail dimension (Galeazzi-(G) N-NAIL) were tested for accuracy. We assessed inter- and intraobserver agreement for the three different settings (in person, video, and pictures).
RESULTS
In our cohort of 382 patients with nail psoriasis after a clinical and dermatoscopic assessment we found 20 (5.24%) patients with onychophagy and 17 (4.45%) patients with onychotillomania. Analysis of the impact of nail psoriasis on patients revealed that onycholysis and crumbing, followed by subungual hyperkeratosis, were the clinical signs that prevalently bothered patients. N-NAIL score displayed moderate intra- and interobserver agreement. Over the 9 months follow-up, N-NAIL vs. GN-NAIL displayed a solid correlation at all the examined time points, i.e., baseline and after 3, 6, and 9 months.
CONCLUSION
We created a new tool, the GN-NAIL capable of efficiently scoring nail psoriasis severity in complex cases, such as patients with onychotillomania and onychophagy, and monitor response to treatment during the COVID-19 pandemic.

BACKGROUND
Dermoscopy has emerged as a useful diagnostic tool to evaluate skin lesions, including psoriasis. We aimed to compare the clinical examination and digital dermoscopy findings of nail involvement in patients with psoriatic nails.
METHODS
This study included 60 patients with clinically diagnosed psoriasis. The nail findings and NAPSI were evaluated clinically and via dermoscopy, and then the severity of the disease was calculated using PASI criteria.
RESULTS
About 32 patients were males, with a median PASI score of 4.4, and pitting and subungual hyperkeratosis were the most common findings. The clinical and dermoscopic examination had a moderate diagnostic resemblance regarding onycholysis, subungual hyperkeratosis, and leukonychia. The resemblance between the two methods for the diagnosis of leukonychia in patients with a duration of disease <2 years (Kappa = 0.59) and 2-6 years was moderate (Kappa = 0.48), and for 6 years< was perfect (Kappa = 0.62). The resemblance for the diagnosis of subungual hyperkeratosis and onycholysis in subjects with a duration of disease <2 years was slight, and for 2-6 years and 6 years< were moderate. The resemblance between the NAPSI score by the two methods was also moderate (95%CI -0.89-0.81, < 0.001).
CONCLUSION
Dermoscopy is an efficient, supportive, and non-invasive method providing a better diagnosis of nail psoriasis.

Subungual Onycholemmal Cyst (SOC) is a rare nail abnormality with different clinical presentations which can mimic different nail malignancies, such as melanoma, SCC, or glomus tumor. It is necessary for dermatologists and dermatopathologist to be aware of this pathology to make the proper diagnosis and treatment. SOC is a rare nail abnormality which affects the dermis of the nail bed. SOC has different clinical presentations, including onychodystrophy, ridging, clubbing, thickening, pigmentation, or even normal appearance. It can mimic different nail malignancies, such as melanoma, SCC, or glomus tumor. In this report, we describe a 54-year-old man with unilateral second right finger nail onychodystrophy and onycholysis for 1 year. He did not have any history of recent trauma, pain, or bleeding. It was completely resected by surgery. Nail biopsy can contribute to the early diagnosis of SOC and improvement of treatment outcomes.

This report describes the clinical, onychoscopic, nail clipping, and histopathologic features of a malignant onychopapilloma. A 71-year-old male presented to our outpatient clinic for a stable, asymptomatic lesion on his left middle finger that had been present for 2 years. Prior nail clipping histopathology showed nail plate thinning with subungual abnormal onychocytes. Clinical examination revealed a 2-mm-wide streak of longitudinal xanthonychia extending to the proximal nail fold, with distal hyperkeratosis and onycholysis. Onychoscopy showed irregular longitudinal nail plate ridging with scattered punctate hemorrhagic foci. An excisional nail unit biopsy demonstrated cellular atypia of the nail bed epithelium, matrix metaplasia, longitudinal abnormal onychocytes, increased Ki-67 staining, and negative HPV immunoperoxidase staining, confirming the diagnosis of malignant onychopapilloma.

INTRODUCTION
Onychopapilloma most commonly presents as longitudinal erythronychia, but diagnosis may be challenging in some cases due to varied clinical presentations. Most patients with onychopapillomas do not report associated pain but instead more commonly report functional interference.
CASE REPORT
We present a case of a 74-year-old female with a 5-year history of splitting and lifting of the right thumbnail, accompanied by nail sensitivity and intermittent painful throbbing. Clinical examination was significant for a less than 1 mm red line with distal onycholysis. Love's test and a cold test performed with ice pack were negative. X-ray of the right thumb was negative for erosion or exostosis. Nail biopsy was performed, and dermatopathology was consistent with onychopapilloma with a concomitant traumatic neuroma.
CONCLUSION
We report a case of onychopapilloma with a concomitant traumatic neuroma. Subungual neuromas are extremely rare and have not previously been associated with onychopapilloma. Our case supports the expansion of the differential diagnosis for a painful nail and demonstrates the importance of diagnostic confirmation with biopsy and histopathology.

Observational Study
INTRODUCTION
Leprosy is a chronic granulomatous infectious disease, mainly affecting the skin and peripheral nerves, caused by the obligate intracellular bacteria Mycobacterium leprae. The disease has been discussed in several review articles in recent research, but as far as we know, only a few have addressed the effects of leprosy on nails, especially those who examine the dermoscopic features of nails in leprosy patients.
PURPOSES
We aimed to document nail changes in leprosy patients and identify any particular findings through dermoscopic examination.
METHOD
This was an observational study conducted in the Dermatology and Venereology Clinic of Hasan Sadikin Hospital, West Java, Indonesia, from March 2023 through May 2023. All patients have established cases of leprosy, and the diagnosis is based on clinical and bacteriological examinations. Recruitment was done through total sampling. Dermoscopic examination of all fingernails and toenails was performed at 10x magnification using a handheld dermatoscope (Heine DELTA 20 T Dermatoscope) in polarized mode without the linkage fluid to document the dermoscopic features.
RESULT
Of a total of 19 patients, 15 had nail changes due to leprosy. Out of 15 patients, 13 patients were male. Patients below 25 years old had more nail changes. Most of the patients had a duration of disease greater than two years. Both fingers and toes were involved in nine patients. In this study, the most common dermoscopic feature found was the longitudinal ridge. Other dermoscopic features found in this study were transverse lines, onycholysis, longitudinal melanonychia, leukonychia, subungual hemorrhage, subungual hyperkeratosis, anonychia, and onychorrexis.
CONCLUSION
Nail changes are found in leprosy patients and have a wide variety of clinical appearances. A dermoscopy should be performed to assess nail changes in leprosy.

Pemphigus vulgaris (PV) mainly causes blistering of the skin and mucous membranes, with nail unit involvement being rare. Nail involvement may serve as an indicator of disease severity. We present a case of a 20-year-old male with PV who had both cutaneous and nail findings, with nail changes corresponding with disease severity. The patient with biopsy-confirmed PV, on prednisone and mycophenolate, presented to the emergency department with an acute flare of PV and severe mandibular pain and lymphadenopathy. At follow-up in our outpatient department, the physical examination was significant for onychomadesis and onycholysis of the fingernails. Prednisone and mycophenolate dosages were increased, and rituximab infusions were initiated. Bullae and mucosal lesions resolved on the follow-up, and nail changes improved. This case appends an unusual perspective to the limited literature on PV-associated nail changes, especially in younger patients. It advocates for meticulous history taking and physical examination and supports a correlation between nail symptoms and PV disease severity.

Onychopapilloma is an uncommon benign tumor of the nail bed and the distal matrix. Objectives: We aimed to investigate the clinical and pathological features of onychopapilloma in Taiwan. We conducted a retrospective analysis of 12 patients with histopathologically proven onychopapilloma in a medical center in southern Taiwan from 2017 to 2023. This case series consisted of 5 men and 7 women aged 29 to 38, with a mean age of 41.25 years. The clinical features were as follows: distal subungual hyperkeratosis (100%), longitudinal erythronychia (50%), longitudinal leukonychia (50 %), distal onycholysis (41%), and distal nail plate fissuring (41%). The duration of the disease varied greatly, ranging from 1 month to several years. Most patients were asymptomatic (58%), while some presented tenderness (41%). Fingernail involvement was more prevalent than toe involvement, with the thumb being the most commonly affected site. Most of the patients presented with a solitary onychopapilloma. None of the seven patients who underwent surgery and were available for follow-up experienced recurrence. This study highlights that longitudinal erythronychia and leukonychia emerged as the predominant clinical presentations of onychopapilloma. Furthermore, our findings suggest that surgical excision appears to be an effective method for onychopapilloma.

Clinics (Sao Paulo, Brazil) 2024To compare the efficacy and safety of larotrectinib with those of infigratinib in adult glioma patients with tyrosine kinase alterations.
OBJECTIVES
To compare the efficacy and safety of larotrectinib with those of infigratinib in adult glioma patients with tyrosine kinase alterations.
METHODS
Patients received oral infigratinib 125 mg (IN cohort, n = 125) or oral larotrectinib (LB cohort, n = 105) until unacceptable toxicity or disease progression.
RESULTS
Duration of treatment was longer in the LB cohort than in the IN cohort (8 [9.5-6.25] months vs. 5.5 [6-5.25] months, p < 0.0001). Patients with partial responses (p = 0.0424) and overall survival (p = 0.03) were higher in the IN cohort than those in the LB cohort. The number of patients with disease progression was higher in the LB cohort (p = 0.0015). All the patients reported diarrhea, fatigue, vomiting, constipation, and decreased appetite. Patients in the IN cohort reported hyperphosphatemia, hyperlipasemia, stomatitis, dry skin, alopecia, dyspepsia, onycholysis, palmar-plantar erythrodysesthesia, nail disorders, and dry eyes. Patients in the LB cohort reported upper respiratory tract infections, pyrexia, cough, anemia, bacterial/viral infections, conjunctivitis, urinary tract infections, headaches, ataxia, dizziness, and muscle tremors. A total of 30 (24 %) and 40 (38 %) patients from the IN and the LB cohorts died at the follow-up of 18 months (p = 0.03). Patients who received bevacizumab initial therapy had higher overall survival (p = 0.048).
CONCLUSIONS
Infigratinib has higher efficacy and overall survival than larotrectinib but has higher adverse effects in the management of both glioma and tyrosine kinase alterations after failure of initial therapies. Initial bevacizumab therapy is associated with a higher overall survival.
