Dear Editor,Dorsal pontine lesions may cause a variety of complex neuro-ophthalmic deficits,including horizontal gaze palsy(HGP),internuclear ophthalmoplegia,one-and-ahalf syndrome,abducens nerve palsy,skew deviation,...Dear Editor,Dorsal pontine lesions may cause a variety of complex neuro-ophthalmic deficits,including horizontal gaze palsy(HGP),internuclear ophthalmoplegia,one-and-ahalf syndrome,abducens nerve palsy,skew deviation,or any combination of these.Here we present a rare case of an adult patient who developed multiple complicated clinical manifestations after surgical removal of a pontine cavernous hemangioma(PCH).Our case highlights a single pontine lesion may involve complicated neural pathways and result in complicated symptoms and signs,in which abducens nerve palsy or skew deviation is easily missed when combined with HGP.展开更多
文摘Dear Editor,Dorsal pontine lesions may cause a variety of complex neuro-ophthalmic deficits,including horizontal gaze palsy(HGP),internuclear ophthalmoplegia,one-and-ahalf syndrome,abducens nerve palsy,skew deviation,or any combination of these.Here we present a rare case of an adult patient who developed multiple complicated clinical manifestations after surgical removal of a pontine cavernous hemangioma(PCH).Our case highlights a single pontine lesion may involve complicated neural pathways and result in complicated symptoms and signs,in which abducens nerve palsy or skew deviation is easily missed when combined with HGP.
文摘Hutch inson-G ilford早老症(HGPS)为一种极为罕见的遗传性疾病,发生率1/8000000,特征性表现为患儿以极快速度衰老,多数死于冠脉病变引起的心肌梗死或广泛动脉粥样硬化导致的卒中,平均寿命13岁。绝大多数HGPS病例病因为LMNA基因第11个外显子发生点突变(G608G),生成的突变lam in A由显性负效应造成细胞核结构和功能受损。目前该病已有几种动物模型,实验性治疗可以在体外将出泡的细胞核恢复正常。HGPS是研究衰老和心血管疾病机制的一个极好的模型。
