PAK has a striking similarity to LM/LMM in clinical and dermatoscopic features, thus representing a diagnostic challange. All dermatoscopic findings except black blotches were observed in PAK. As dermatoscopic diagnosis of a pigmented skin lesion cannot be based on the presence of a single criterion, we may conclude that histopathology still remains the gold standard for correct diagnosis.
Both sodium hydroxide and phenol are effective agents giving high success rates, but sodium hydroxide causes less postoperative morbidity and provides faster recovery.
Calibre persistent labial artery (CPLA) is defined as a primary arterial branch that penetrates into the submucosal tissue without division or decrease in diameter. It usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a varix, haemangioma, venous lake, mucocele or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. The most frequently used method to confirm the diagnosis of CPLA has been excisional biopsy, which carries the risk of profuse bleeding. Angiography, another invasive method, has also been used. Here, we report a case of a 20-year-old woman with a 5-year history of multiple CPLA lesions involving both upper and lower lips. In this case, the diagnosis was made clinically and confirmed by Doppler ultrasonography, which is a noninvasive and simple diagnostic tool.
The existing regional prevalance studies conducted in Turkey have indicated that the real number of Behçet's patients in our country is markedly higher than the number of registered patients. Therefore the National Behçet's Disease Commity and Surveillance System was founded by our research group in December 1999.
Aim: To investigate the prevalence and clinical characteristics of vitiligo after allogeneic hematopoietic cell transplantation (AHCT). Methods: The development of vitiligo was analyzed among 421 patients who underwent AHCT in Ibni Sina Hospital (University of Ankara) between 1988 and 2004. Results: Among 421 patients, we describe 6 with generalized vitiligo occurring after AHCT for chronic myelogenous leukemia. Five of them had severe chronic graft-versus-host disease (GVHD). Vitiligo was accompanied by alopecia areata and acquired ichthyosis in 2 patients with GVHD. Conclusion: Melanocyte destruction caused by the autoimmune reactions triggered by chronic GVHD as well as a genetic predisposition might have played a role in the development of vitiligo in our patients. These data support the hypothesis that vitiligo is an autoimmune entity.
OBJECTIVE. Sodium hydroxide matricectomy is a successful method for the treatment of ingrown toenails. This study was designed to evaluate the optimal sodium hydroxide application period providing high success rates with minimal postoperative morbidity.MATERIALS AND METHODS. Sixty-six patients with 225 ingrown nail edges were treated in three groups receiving 30-second, 1-minute, and 2-minute applications of sodium hydroxide. Each patient was reviewed postoperatively for pain, drainage, and tissue damage. The median long-term follow-up period was 14 months.RESULTS. The success rate of the therapy was 70.9% in the first group, 92.7% in the second group, and 94.4% in the third group. In all groups, about half of the patients experienced minimal pain within 48 hours following the operation, but only in the third group, 20% of the patients had minimal pain, which continued about 1 week. Drainage and tissue damage were minimal or mild in all groups and disappeared within 3 weeks in the first and second groups but were prolonged to 6 weeks in the third group.CONCLUSION. The success rate of 30-second application is significantly lower than 1-minute and 2-minute applications. Although the success rates of the latter two procedures are similar, the prolonged healing time is the disadvantage of the 2-minute application. We conclude that 1-minute application of 10% sodium hydroxide is simple, safe, and highly effective for the treatment of ingrown nails.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
