Preliminary Evidence of the Efficacy of Nitric Acid Treatment in Onychomycosis

Onychomycosis is the main cause of toenail disorders and is produced by a fungal infection. It is becoming more prevalent because of new lifestyles and immunosuppression statuses. The therapeutic approach to onychomycosis is under considerable study because of the lengthy treatments that require strong patient commitment, the limited efficacy of treatments, the inclusion of active substances that can be hepatotoxic and cause pharmacological interactions, and/or the questionable efficacy of treatments due to a lack of clinical trials. This study responds to the demand for rapid treatment with minimal pharmacological interactions. Methods: The efficacy of nitric acid 60% treatment in patients with onychomycosis was monitored and studied. The antifungal efficacy of nitric acid was measured by microbiological culture before and after treatment and the clinical evolution of nail dystrophy was quantitatively measured by monitoring with the Onychomycosis Severity Index (OSI). Results: The results show that, with the protocol used, nitric acid 60% painlessly cured 40% (microbiologic cure) of the cases treated, and in all cases, clinical improvement was observed (p = 0.011). Conclusions: The treatment with nitric acid 60% is as efficient as conventional treatments, requires less patient compliance of the treatment and produces no pharmacological interactions, providing alternative treatment in the case of hepatotoxicity.

Dyskeratosis congenita: rare case report of Syria

ABSTRACT Dyskeratosis congenita (DC) is an inherited disease characterized by the triad of abnormal skin pigmentation, nail dystrophy and mucosal leukoplakia. Non-cutaneous abnormalities (dental, gastrointestinal, genitourinary, neurological, ophthalmic, pulmonary and skeletal) have also been reported. Bone marrow failure (BMF) is the main cause of early mortality, with an additional predisposition to malignancy. DC results from an anomalous progressive shortening of telomeres resulting in DNA replication problems inducing replicative senescence. Men are more affected than women are and X-linked recessive, autosomal dominant and autosomal recessive forms of the disease are recognized. There are no targeted therapies for DC. Patients treated with androgens had a hematological response. We herein describe case of a 32-year-old man, presented with several characteristic systemic features of this condition, including the classic triad of lesions, dysplastic bone marrow, epiphora and liver cirrhosis with grade I esophageal varices. Therefore, a prophylactic propranolol was started in additional to danazol. Three-week later, the patient had subsequent increases in his platelet, red cell and white cell counts.

Equivocal Longitudinal Melanonychia in a 3-Year-Old Caucasian Girl: Rapid Evolution and Fading during Digital Dermoscopy Follow-Up

<b><i>Introduction:</i></b> Nail matrix nevi (NMN) in pediatric patients manifest as longitudinal melanonychia (LM) and can share clinical, dermoscopic, and histopathological characteristics with subungual melanoma. Equivocal findings in childhood LM may reflect dynamic processes during the natural life cycle of NMN in children. <b><i>Case Presentation:</i></b> We present a case of a heavily pigmented LM with equivocal clinical and dermoscopic findings in a 3-year-old Caucasian girl, which exhibited signs of evolution, maturation, and almost complete involution within a short time period during digital follow-up, attributed to the natural course of NMN. <b><i>Discussion/Conclusion:</i></b> Considering the rarity of subungual melanoma in childhood, our case underlines the significance of clinical and digital dermoscopy follow-up in the evaluation of childhood LM in order to avoid unnecessary biopsies and potential permanent nail dystrophy.

A Single Nail Dystrophy as a Unique Manifestation of Sarcoidosis: A Case Report

Sarcoidosis with nail involvement is rare and most commonly affecting plural digits. Nail changes are frequently an indication of systemic disease and underlying bone involvement, thus complete clinical evaluation with bone and thorax radiological examination is a necessity in suspected cases. We report a case of onychodystrophy with osseous involvement of only one finger as unique manifestation of sarcoidosis, which is very rare.

Congenital Malalignment of the Great Toenail, the Disappearing Nail Bed, and Distal Phalanx Deviation: A Review

<b><i>Importance:</i></b> Congenital malalignment of the great toenail (CMGT) is an idiopathic deviation of the nail apparatus. CMGT predisposes patients to recurrent stress forces, microtrauma, and secondary complications. The purpose of this study was to review the current published photographs to determine the relationship between variants of CMGT and the disappearing nail bed (DNB). <b><i>Observations:</i></b> A search in PubMed and Google using the terms congenital malalignment of the great toenail, disappearing nail bed, and lateral nail deviation was performed. Of the 53 photographs found in a total of 35 articles, 23 were disqualified due to low picture resolution or poor angle. The remaining 30 photographs were evaluated. Pure nail malalignment with associated dystrophy and DNB was found in 22 of 30 photographs. Four of 30 cases demonstrated pure deviation of the distal phalanx, with nail dystrophy but minimal DNB. The remaining 4 cases demonstrated a combination of toe deviation and nail unit deviation with varying degrees of DNB. <b><i>Conclusions and Relevance:</i></b> DNB was associated with all forms of pure CMGT. Moreover, a variant of malalignment of the distal phalanx was noted in 8 photographs. This has potential implications for further studies and treatment to correct secondary complications.
