Bilateral optic nerve edema presenting as initial manifestation of thyroid eye disease

A 48-year-old smoker with a history of hyperthyroidism treated 10 years prior to presentation with radioactive iodine ablation of the thyroid gland presented to his ophthalmologist with a 2-week history of transient loss of vision in the right eye occurring for 1 to 2 hours each morning. He denied ocular pain, diplopia or change in the prominence of one or both eyes. Examination revealed 2 mm of relative proptosis on the right, bilateral temporal flare and lower lid retraction. There was minimal upper lid retraction and no evidence of lid lag. Ocular motility was full. Dilated fundoscopic examination revealed bilateral optic nerve edema, right more than left. CT of the orbit demonstrated enlargement of the extraocular muscles bilaterally with marked enlargement of the right medial rectus and left inferior rectus muscles resulting in crowding at the orbital apex bilaterally. Laboratory testing revealed the patient to be hyperthyroid. The patient was treated with high dose oral steroids followed by orbital radiation. Hyperthyroidism was managed by the patient’s primary care physician. Visual symptoms rapidly improved with oral steroids and orbital radiation. Optic nerve edema completely resolved. Repeat CT imaging demonstrated a reduction in the enlargement of the extraocular muscles with relief of bilateral optic nerve compression.     

肿瘤坏死因子与甲状腺细胞凋亡及相关蛋白的检测和表达的意义

目的　探讨肿瘤坏死因子 a(TNF a)诱导Graves病甲状腺细胞凋亡与相关蛋白表达在Graves病 (GD)发病关系中的意义。方法　采用免疫组织化学S P方法检测 5 0例Graves病患者TNF a,并检测对照组对Fas表达的影响。采用原代细胞培养方法进行细胞培养 ,细胞培养液中的sFas含量采用ELISA法检测。Fas/sFasmRNA检测采用半定量RT PCR法。结果　含有TNF aGD组细胞凋亡率为 92 6 % ,显著高于对照组的凋亡率 (36 0 % ) (P <0 0 1)。其含有TNF aGD组甲状腺细胞sFas、Fas/sFasmRNA含量与对照组比较差异有显著意义 (P <0 0 1)。结论　TNF a诱导Graves病甲状腺细胞凋亡及凋亡相关蛋白sFas、Fas/sFasmRNA有一定水平的表达 ,这些改变可能是TNF a破坏甲状腺细胞的重要机制之一。     

Paracentral Corneal Dellen： A Rare Sign of Graves Ophthalmopathy

Purpose:To report a rare sign, paracentral corneal dellen that developed in a middleaged female patient with Graves ophthalmopathy.Methods:A paracentral corneal dellen developed in the left eye in a 42-year-old woman who was diagnosed as Graves ophthalmopathy. The patient had remarkable upper eyelid retraction, upper eyelid lag and upward motility restriction. The Graves ophthalmopathy was classified as Grade Ⅳ according to NOSPECS classification.Results:Local artificial tear film and 0.3％ Tobramycin eye drops were administered to both eyes.Twenty-four hours later, the left corneal dellen disappeared.Conclusions:Graves ophthalmopathy can lead to paracentral corneal dellen because of severe upper eyelid retraction and upward motility restriction of the eye in spite of the lack of lagophthalmos. Artificial tear drop and antibiotic eye drop therapy helped even though the patient did not have corneal exposure. Eye Science 2003;19:174-175.     

汉族、哈萨克族Graves病患者血清CoL IV、LN和HA测定分析

用放免法(单克隆抗体)测定汉、哈萨克族Graves病未经治疗患者66例及正常对照组55例血清中Ⅳ型胶原(CoLⅣ)、板层素(IN)和透明质酸(HA),结果Graves病患者血清CoLⅣ、LN浓度明显升高,HA浓度明显降低,与正常对照组相比均有显著性差异(分别P<0.001、P<0.05、P<0.05),汉族与哈萨克族患者之间、对照组之间相比均无显著性差异(P>0.05),它反映了Graves病患者体内基底膜合成和分解代谢紊乱。     

Graves病患者血甲状旁腺激素、钙、磷、碱性磷酸酶基础值的观察

对照观察了28例Graves病患者及29名正常人血浆甲状旁腺激素、(PTH)血钙、血磷、碱性磷酸酶的基础值。Graves病组血碱性磷酸酶明显高于对照组,而PTH、钙、磷无显著差异。Graves病组血钙>2.75mmol/L者占21%,与某些文献大致相符。正常组血钙与PTH基础值间呈负相关,而Graves病组该两值间无相关,提示Graves病时血钙浓度的平衡调节中PTH以外的因素如甲状腺激素等可能对其影响较大。     

131Ⅰ治疗Graves病剂量探讨

目的　探讨1 31 Ⅰ治疗Graves病时 ,不同的剂量计算方法与治愈率以及治疗后并发症的关系。方法　在计算治疗Graves病所需1 31 Ⅰ时 ,分别采取不同的两种计算方法 ,观察两者治愈率及并发症的发生情况 ,并做多因素对比分析。结果　治疗组较对照组 1次治愈率提高约 12 % ,近期甲状腺功能减退延续为永久性甲状腺功能减退者亦明显减少 ,治疗效果明显优于后者。结论　1 31 Ⅰ治疗剂量计算时 ,既要有公式的规范性 ,又要有根据具体情况调节的灵活性 ,即可明显提高治疗效果     

GraVes眼病炎性活动期与静止期血清sICAM-1水平的研究

目的:研究可溶性细胞间粘附因子-1(sICAM-1)在Graves眼病(GO)炎性活动期与静止期的水平差异及其与各项甲状腺功能指标的关系。方法:将GO炎性活动期与静止期患者,Graves病(GD)无眼病患者及正常对照,分为A、B、C、D四组,抽取空腹静脉全血,测血清sICAM-1,各组间进行比较。并分析各组sICAM-1与FT3、FT4、TG、TM的相关关系。结果:①A、B、C组患者血清sICAM-1均明显高于正常对照组(P<0.05)。A组患者sICAM-1水平最高,与B组及C组患者相比有统计学差异(P<0.01);②前三组各组内sICAM-1与FT3、FT4成直线相关关系,与TG、TM成直线相关关系;③GO炎性活动期患者sICAM-1与GO评分成正相关。结论:血清sICAM-1水平可作为反映GO活动性评判的免疫指标,长期监测sICAM-1可预示GD进展为临床活动性眼病的可能性。     

心理因素的应激对GraVes癌患者免疫系统的影响

目的探讨社会心理因素的应激对Graves病患者的免疫系统的影响.方法采用定式问卷,统一指导语和填表方法及有关评定量表评分,并以放射免疫法,对40例患者测定IgG、IgA、IgM及C3、C4、IL-2、I1-6与40例正常健康者对照.结果病例组IgG、IgA及IL-6显著高于正常对照组,而C3、C4及IL-2显著低于对照组.患者的抑郁分与IgG、IgA及IL-6呈明显正相关,与IL-2呈显著负相关.结论因为IgA及IL-6是疾病的危险因子,C4及IL-2是疾病的保护因子,所以社会心理因素的应激可以通过Gra-ves病患者的免疫系统而影响疾病.
