Publication Open Access Frequency and risk factors for secondary malignancies in patients with mycosis fungoides(2016-08-01) EMIROGLU, NAZAN; CENGIZ, F. P.; BAHALI, A. Gulsel; Su, O.; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEMycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma (CTCL), has an incidence of 6.4 per million people [1]. Patients with CTCL have an increased risk of the development of secondary malignancies, particularly lymphomas [2,3]. We conducted a 20-year population-based cohort study to assess the risk factors of secondary cancers in MF patients from our center.Publication Open Access Acne located on the trunk, whey protein supplementation: Is there any association?(2017-03-05) CENGIZ, FATMA PELİN; Cevirgen, Cemil; EMIROGLU, NAZAN; Gulsel, Bahali; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; ONSUN, NAHIDEWhey protein is a source of protein that was isolated from milk. Whey proteins are composed of higher levels of essential amino acids. The role of diet in acne etiology has been investigated for several years. It was established that milk and milk products can trigger acneiform lesions, and recent evidence supports the role of whey protein supplements in acne. Herein, we report 6 healthy male adolescent patients developing acne located only to the trunk after the consumption of whey protein supplements for faster bodybuilding. This is the first observation which specified the location of acneiform lesions among bodybuilders. In our opinion, a trendy and common health problem is beginning among adolescents in the gyms.Publication Metadata only Dermoscopic Evolution of Pediatric Nevi(2019-10-01T00:00:00Z) CENGİZ, Fatma Pelin; Yilmaz, Yaren; EMİROĞLU, Nazan; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; ONSUN, NAHIDEBackground: The incidence of pediatric melanoma is very rare. Dermoscopic features help to distinguish pediatric melanoma and common nevi. Objective: To study the evolution of dermoscopic findings in benign nevi in childhood through serial observation and photography. Methods: We examined 504 melanocytic lesions in 100 patients. From each participant, dermoscopic images of the nevi from 4-year dermoscopic follow-up were obtained, including randomly selected nevi. Results: The most common dermoscopic patterns were homogeneous (193 nevi; 38.3%), globular (92 nevi; 18.3%), and reticular (86 nevi; 17.1%). Dermoscopic pattern changes were detected in 27% of patients aged 2 similar to 10 years and in 20% of patients aged 11 similar to 16 years. The main pattern changes consisted of the transition from homogeneous to globular-homogeneous (16%), from homogeneous to reticular-homogeneous (12%) and from globular to globular-homogeneous (10%). Although 257 of the 504 nevi (51.0%) have stable duration without size changes, 169 of the 504 nevi (33.5%) were enlarged, and 78 of the 504 nevi (15.5%) had become smaller. Conclusion: These results contrast with the prevailing view that dermoscopic patterns in pediatric nevi are usually characterized by globular patterns and that melanocytic nevi generally undergo a characteristic transition from a globular pattern to a reticular pattern. Fifty one percent of patients did not exhibit a size change. While 33% of patients had symmetrical enlargement, 15% of patients had involution. Therefore, enlargement is a common dermoscopic change in pediatric nevi, and is not a specific sign of pediatric melanoma.
