概括
区分ABCA4和PRPH2相关的视网膜疾病可能具有挑战性. 这项研究确定了关键的成像特征,比如ABCA4的周节省和PRPH2的黄斑缩,有助于临床诊断.
科学领域:
- 眼科医生 眼科 眼科
- 医学遗传学 医学遗传学
- 视网膜成像分析分析
背景情况:
- 与ABCA4和PRPH2相关的视网膜疾病具有重叠和异质的表型,使得临床区分变得困难.
- 识别不同的临床和成像特征对于准确诊断和管理这些遗传性视网膜疾病至关重要.
研究的目的:
- 识别和比较与ABCA4相关的和PRPH2相关的视网膜疾病患者之间的特定检查和成像发现.
- 确定某些特征是否可以预测患有这些疾病的患者的遗传基因型.
主要方法:
- 一个单一中心的患者队列的回顾性分析,该队列的患者在ABCA4或PRPH2中具有致病变异的分子确认.

Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
