    阿那曲唑是一种内分泌调节剂,用于治疗绝经后乳腺癌人群中的雌激素敏感性乳腺癌。阿那曲唑以其副作用而闻名,其中包括骨质疏松症的风险增加。然而,文献中以案例研究形式出现的证据表明,由于使用该药物,一些潜在的眼部副作用。在我们的研究中,一名使用阿那曲唑的66岁女性患有严重的双侧乳头水肿,停药后缓解.越来越多的证据表明阿那曲唑的使用及其对眼睛健康的影响导致有害的副作用,比如乳头水肿。
    Anastrozole is an endocrine-modifying agent used in the treatment of estrogen-sensitive breast cancer in the postmenopausal breast cancer population. Anastrozole is known for its side effect profile which includes an increased risk of osteoporosis. However, emerging evidence in the literature in the form of case studies demonstrates several potential ocular side effects due to the use of the medication. In our study, a 66-year-old female using anastrozole suffered severe bilateral papilledema that resolved after cessation of the medication. There is a growing body of evidence demonstrating the use of anastrozole and its impact on ocular health leading to deleterious side effects, such as papilledema.

    由黄体生成素释放激素激动剂(LHRHa)引起的化学烧伤是一种罕见的不良反应,在现有文献中尚未有充分记载。在这个案例报告中,我们报道了一次皮下注射戈舍瑞林后出现的部分厚度烧伤.据我们所知,这是文献中对戈舍瑞林引起的化学烧伤的首次描述。必须强调早期识别和治疗LHRHa相关皮肤反应的重要性,以确保最佳的肿瘤管理和患者舒适度。
    A chemical burn resulting from luteinizing hormone-releasing hormone agonists (LHRHa) is a rare adverse effect that has not been well-documented in prior literature. In this case report, we report a partial-thickness burn that developed following a single subcutaneous injection of goserelin. To our knowledge, this is the first description of goserelin-induced chemical burn in the literature. The importance of early identification and treatment of LHRHa-associated cutaneous reactions must be highlighted to ensure optimal oncologic management and patient comfort.

    来曲唑是一种口服芳香化酶抑制剂,用于治疗绝经后妇女的激素受体阳性乳腺癌。它通过抑制雄激素向雌激素的转化而起作用,从而降低体内的雌激素合成。我们报告了一名绝经后妇女因来曲唑治疗乳腺癌而出现双侧囊样黄斑水肿(CME)的病例。一名62岁的女性在过去6个月中表现为无痛的逐渐进行性双侧视力下降。她以前的眼部病史并不引人注目。她的病史以乳腺癌而闻名,为此她接受了化疗,然后进行了乳房切除术,辅助激素治疗,和放射治疗。该患者在过去4½年中一直服用来曲唑。在介绍时,右眼的最佳矫正视力为0.4,左眼为0.5。眼底检查显示明显的双侧CME。光学相干断层扫描和眼底荧光血管造影证实了诊断。在与治疗肿瘤学家讨论来曲唑相关性黄斑病变的可能性后,停用来曲唑,并对患者进行重新评估.当随后停止来曲唑时,观察到黄斑水肿的减少和轻度视觉改善。虽然来曲唑的眼部副作用很少见,对于存在视觉障碍的患者,建议进行全面的眼科评估,以便及时进行干预.
    Letrozole is an oral aromatase inhibitor used in the treatment of hormone receptor-positive breast cancers in postmenopausal women. It acts by inhibiting the conversion of androgens to estrogen thereby lowering the estrogen synthesis in the body. We report a case of bilateral cystoid macular edema (CME) in a postmenopausal woman on letrozole for breast cancer. A 62-year-old female presented with painless gradually progressive bilateral diminution of vision for the past 6 months. Her previous ocular history is unremarkable. Her medical history is known for carcinoma of the breast for which she underwent chemotherapy followed by mastectomy, adjuvant hormonal therapy, and radiotherapy. The patient had been on letrozole for the past 4½ years. At presentation, the best corrected visual acuity in the right eye was 0.4 and 0.5 in the left eye. Fundus examination revealed significant bilateral CME. Optical coherence tomography and fundus fluorescein angiography confirmed the diagnosis. After discussing the possibility of letrozole-related maculopathy with the treating oncologist, letrozole was discontinued and the patient was reassessed. Reduction of macular edema and mild visual improvement was observed when letrozole was subsequently stopped. Although ocular side effects are rare with letrozole, a comprehensive ophthalmic evaluation is recommended for patients who present with visual disturbances for prompt intervention.

    大多数因21-羟化酶缺乏症而患有非经典先天性肾上腺增生(NC-CAH)的儿童无症状,除非出现高雄激素血症的症状,否则不需要皮质醇替代疗法。目前的做法是用氢化可的松治疗有症状的儿童,目的是抑制肾上腺雄激素的过量产生,而与儿童内源性皮质醇的产生水平无关。一旦接受氢化可的松治疗,即使是皮质醇产生正常的儿童也需要压力剂量。一些患有NC-CAH的儿童可能会出现过早的肾上腺素,增长加速,和先进的骨龄,但没有生殖器男性化和正常内源性皮质醇产生的迹象。在这些情况下,氢化可的松治疗的替代疗法,不影响下丘脑-垂体-肾上腺轴,但是目标是增加雌激素的产生及其对骨成熟的影响,可以考虑。芳香化酶抑制剂(AIs),阻止雄激素芳香化为雌激素,已在身材矮小的男性中使用标签外,以延迟骨骼成熟,并作为经典CAH儿童的辅助治疗。从未报道过将AI用作NC-CAH儿童的单一疗法。我们介绍了三名青春期前女性儿童,他们在骨龄晚期后诊断为NC-CAH,接受阿那曲唑单药治疗。早期的肾上腺素,没有生殖器男性化的迹象,和正常峰值皮质醇响应ACTH刺激测试。骨龄z评分归一化,三个人都达到或超过了目标高度。在NC-CAH和正常肾上腺皮质醇产生的儿童中,阿那曲唑的单一疗法可以有效地减缓骨骼成熟并改善身高结果。
    Most children with non-classic congenital adrenal hyperplasia (NC-CAH) due to 21-hydroxylase deficiency are asymptomatic and do not require cortisol replacement therapy unless they develop symptoms of hyperandrogenemia. The current practice is to treat symptomatic children with hydrocortisone aimed at suppressing excess adrenal androgen production irrespective of the child\'s level of endogenous cortisol production. Once on hydrocortisone therapy, even children with normal cortisol production require stress dosing. Some children with NC-CAH may present with premature adrenarche, growth acceleration, and advanced bone age, but with no signs of genital virilization and normal endogenous cortisol production. In these cases, an alternative therapy to hydrocortisone treatment that does not impact the hypothalamic-pituitary-adrenal axis, but targets increased estrogen production and its effects on bone maturation, could be considered. Aromatase inhibitors (AIs), which block the aromatization of androgen to estrogen, have been used off-label in men with short stature to delay bone maturation and as an adjunct therapy in children with classic CAH. The use of AI as a monotherapy for children with NC-CAH has never been reported. We present three pre-pubertal female children with a diagnosis of NC-CAH treated with anastrozole monotherapy after presenting with advanced bone age, early adrenarche, no signs of genital virilization, and normal peak cortisol in response to ACTH stimulation testing. Bone age z-scores normalized, and all three reached or exceeded their target heights. Monotherapy with anastrozole can be an effective alternative in slowing down bone maturation and improving height outcomes in children with NC-CAH and normal adrenal cortisol production.

    目的:描述一名镰状细胞病患者,血栓前疾病,在造血干细胞移植之前,为了保存生育能力而进行了成功的胚胎冷冻保存。
    方法:报告一例成功的促性腺激素刺激和胚胎冷冻保存的案例,使用芳香化酶抑制剂来曲唑维持低血清雌二醇,以降低镰状细胞病(SCD)和视网膜动脉血栓形成史计划造血干细胞移植(HSCT)患者的血栓形成风险。在HSCT之前,患者接受来曲唑(每天5mg)以及预防性依诺肝素,同时使用拮抗剂方案进行促性腺激素刺激以保持生育能力。取卵后,来曲唑再继续治疗一周.
    结果:患者在促性腺激素刺激期间的血清雌二醇峰值浓度为172pg/mL。回收10个成熟卵母细胞,冷冻保存总共10个胚泡。由于疼痛,患者在取卵后需要止痛药和静脉输液,但在预定的术后第一天随访中有显着改善。在刺激期间或其后6个月未发生栓塞事件。
    结论:干细胞移植治疗SCD的应用正在增加。我们成功地使用来曲唑在促性腺激素刺激期间与预防性依诺肝素一起维持低血清雌二醇,以减少血栓形成的风险。这种方法将使计划通过干细胞移植进行明确治疗的患者有机会安全地保持其生育能力。
    OBJECTIVE: To describe a patient with sickle cell disease, a prothrombotic disorder, who underwent successful embryo cryopreservation for the purposes of fertility preservation prior to hematopoietic stem cell transplant.
    METHODS: To report a successful case of gonadotropin stimulation and embryo cryopreservation using the aromatase inhibitor letrozole to maintain low serum estradiol to minimize thrombotic risk in a patient with sickle cell disease (SCD) and history of retinal artery thrombosis planning hematopoietic stem cell transplant (HSCT). The patient was given letrozole (5 mg daily) as well as prophylactic enoxaparin while undergoing gonadotropin stimulation with an antagonist protocol to preserve fertility prior to HSCT. After the oocyte retrieval, letrozole was continued for one additional week.
    RESULTS: The patient\'s peak serum estradiol concentration was 172 pg/mL during gonadotropin stimulation. Ten mature oocytes were retrieved and a total of 10 blastocysts were cryopreserved. The patient required pain medication and intravenous fluids after oocyte retrieval due to pain but had significant improvement at the scheduled post-operative day one follow-up. No embolic events occurred during stimulation or 6 months thereafter.
    CONCLUSIONS: The utilization of definitive treatment for SCD with stem cell transplant is increasing. We successfully used letrozole to maintain low serum estradiol during gonadotropin stimulation along with prophylactic enoxaparin in a patient with SCD to minimize her risk of thrombosis. This approach will allow patients planning definitive treatment with stem cell transplant the opportunity to preserve their fertility safely.

    Globally, breast cancer is the most frequently diagnosed malignancy among women; it is also one of the leading causes of cancer mortality among females. The most common sites for metastases are the lungs, bones, liver, and brain. Breast cancer is recognized as one of the most common primary sites of metastatic lesions in the ovaries and is often associated with multiple extra-ovarian metastases. Here, we report a case of occult breast cancer metastases to the ovaries with a down-regulated hormonal immunohistochemistry profile after endocrine therapy, encountered incidentally after oophorectomy.

    Primary mucinous carcinoma of the skin (PMCS) is a rare malignant neoplasm of the sweat glands that has an incidence of 1 per 150,000 population. Because of the lack of typical characteristics, it is often misdiagnosed as an epidermoid cyst, pilomatrixoma, or chalazion before resection, with subsequent enucleation performed unintentionally. We present a case of a 51-year-old patient with PMCS in the upper eyelid that was successfully treated at our hospital. Additionally, we reviewed the literature and discussed the diagnosis, primary and adjuvant therapy, and follow-up procedure.

    Hyperparathyroidism-jaw tumor (HPT-JT) is an autosomal dominant disorder responsible for benign and/or malignant tumors. Affected women often present life-threatening menorrhagia that leads to the identification of uterine tumors, and experience miscarriages and infertility. Overall though, fewer data concerning gynecological pathologies related to HPT-JT syndrome are available. We report the case of a 32-year-old woman with HPT-JT syndrome, referred for recurrent vaginal bleeding, with a history of repeated endometrial polyps and infertility. We also review the literature that explores medical options for these women.

    BACKGROUND: Treatment with aromatase inhibitors (AI) is a potential novel treatment in patients with congenital adrenal hyperplasia (CAH) and advanced bone age (BA), to increase near adult height (NAH). Not much is known about the efficacy of AI treatment in CAH and how AI treatment will influence the management of corticosteroid treatment.
    METHODS: At the age of 6 years and 3 months, a boy with salt-losing CAH presented with a BA 7 years in advance. Treatment with an AI (exemestane) was initiated to decelerate bone maturation. We continued the standard dosage of corticosteroid treatment. Precocious puberty was treated with 4 years of gonadotropin-releasing hormone agonist, while AI treatment was continued until attainment of NAH. His NAH 177.7 cm (-0.8 SDS) was considerably higher than his predicted adult height of 151.3 cm (-4.6 SDS) at the start of AI treatment. The higher serum androgen levels during AI treatment did not result in short adult stature.
    CONCLUSIONS: This report shows that AI treatment can adequately decelerate bone maturation, causing predicted adult height to increase significantly in patients of CAH with accelerated bone maturation. We suggest continuing the same corticosteroid dosage during AI treatment and accepting higher serum androgen levels.
