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.     

甲状腺机能亢进危象：附14例临床分析

本文报道14例甲亢危象,其发病率为4.5％,其发病与感染、劳累、情绪激动及同位素治疗有关。指出同位素治疗甲亢初期应服用抗甲状腺药物,讨论了淡漠型危象的有关问题。     

原发性甲状腺功能亢进症合并甲状腺癌18例分析

目的：探讨原发性甲状腺功能亢进症（甲亢）合并甲状腺癌（甲癌）的诊断和治疗。方法：回顾分析1990年1月于2000年1月手术治疗18例甲亢合并甲癌患者的临床资料，结果：微小癌占83％（15／18）。术前彩超检查15例，14例发现可疑结节；13例行癌侧叶全切除和对侧叶次全切除术，5例行双侧叶次全切除术，其中3例同时行颈淋巴结清扫术，1例二次行颈淋巴结清扫术。随访16例，平均随访7年，1例死于癌肺转移，余者仍存活，结论：术前常规彩超检查发现可疑结节有助于术中冰冻切片病理检查，手术治疗应兼顾甲亢和甲癌。     

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。     

跟腱反射时间测定评价甲状腺功能的探讨

对103名甲状腺功能正常者,89例甲状腺功能亢进症(甲亢)患者,10例甲状腺机能减退症(甲低)患者,分别测定了跟腱反射时间并与放免测定血清T_3、T_4相比较。结果:甲状腺功能正常者符合率为100％,甲亢符合率为83％,甲低符合率为90％。认为,跟腱反射时间测定对甲状腺功能的判断比较淮确,并且方法简便易行。
