The Sound System of Ezha, Ethio-Semitic
Abstract: This article is devoted to present a descriptive account of Ezha phonology. The various speech sounds of the language are approached from the perspective of their individual articulatory characteristics and from the perspective of the ways in which they pattern together. A total of thirty three consonant and seven vowel phonemes are attested. In terms of phoneme clustering, Ezha sounds can assume four different patterns: Sonorant-Obstruent, Obstruent-Sonorant, Sonorant-Sonorant, and Obstruent-Obstruent …

Role of Aspirin on Keloid: A Case Report
Abstract: A keloid is a cutaneous mass that characteristically develops following dermal injury. Keloids extend beyond the borders of the original wound invading normal skin. Usually appear as firm nodules, often pruritic and painful, and generally do not regress spontaneously. Most often occur on the chest, shoulders, upper back, back of the neck, and earlobe. We report a case of excessive keloid formation in a 40-year-old female following itching in which …
