Benign familial fleck retina.
A family with a benign form of fleck retina is described. Seven out of 10 siblings were affected. The consanguinious parents were both normal. The fundi were massively invaded by lesions which appeared as discrete, bright white or yellow flecks situated well behind the retinal blood vessels. The macula was always free. Fluorescein studies revealed a healthy macula and retinal and choroidal bloo...
متن کاملthree cases of benign flecked retina syndrome
purpose: to present 3 rare cases of benign flecked retina syndrome. patients and finding: a 19-year-old female patient presented with fundus albipunctatus appearance in fundoscopy without night blindness and normal dark adaptation time on electeroretinography (erg). after 9 years of follow up, no change in visual acuity, erg, or other ophthalmologic examinations was seen. two members of her fam...

Let p be a prime, and let n > 1 and r be integers. In this paper we study Fleck’s quotient Fp(n, r) = (−p) X
متن کاملFleck Quotients and Bernoulli Numbers
Nowadays this result plays important roles in many aspects. Recently Sun and Wan investigated Fp(n, r) mod p in [SW2]. In this paper, using p-adic methods we determine (Fp(m, r) − Fp(n, r))/(m − n) modulo p in terms of Bernoulli numbers, where m > 0 is an integer with m 6= n and m ≡ n (mod p(p − 1)). Consequently, Fp(n, r) mod pordp(n)+1 is determined; for example, if n ≡ n∗ (mod p− 1) with 0 <...
متن کاملArith . POLYNOMIAL EXTENSION OF FLECK ’ S CONGRUENCE
Let p be a prime, and let f (x) be an integer-valued polynomial. By a combinatorial approach, we obtain a nontrivial lower bound of the p-adic order of the sum k≡r (mod p β) n k (−1) k f k − r p α , where α β 0, n p α−1 and r ∈ Z. This polynomial extension of Fleck's congruence has various backgrounds and several consequences such as k≡r (mod p α) n k a k ≡ 0 mod p n−p α−1 ϕ(p α) provided that ...
