METHODS: We tested thyroid function and thyroid antibodies and performed an ophthalmologic examination and neck ultrasound in two patients with autoimmune hypothyroidism converted to GD during a follow-up of several years. CASE REPORTS: The first case is a 33 year-old woman with hypothyroidism due to Hashimoto's thyroiditis (HT)...

BACKGROUND: Fractionated stereotactic radiotherapy (FSRT) is a common modality used to treat pituitary adenomas with good control rates. It is currently unknown whether FSRT should be performed early or delayed until progression occurs. OBJECTIVE: We compared FSRT in treating non-functional pituitary adenomas (NFPA) as an adjuvant (ADJ) or on-progression (PRG) therapy. METHODS: A retrospective review of patients who underwent FSRT for a NFPA between January 2004 to December 2022 at a single institution was performed...

OBJECTIVES: Continuity of care measures are widely used to evaluate the quality of health care delivery, but which visits are included vary across studies. Our objective was to determine how the provider specialties included affect continuity values, year-to-year stability, and association with emergency department (ED) visits. STUDY DESIGN: Retrospective study of Alabama Medicaid administrative data. METHODS: We included beneficiaries with diabetes who had at least 3 outpatient visits in each of 2018 and 2019 (N = 9578)...

The hypothalamic peptide growth hormone-releasing hormone (GHRH) stimulates the secretion of growth hormone (GH) from the pituitary through binding and activation of the pituitary type of GHRH receptor (GHRH-R), which belongs to the family of G protein-coupled receptors with seven potential membrane-spanning domains. Splice variants of GHRH-Rs (SV) in human tumors and other extra pituitary tissues were identified and their cDNA was sequenced. Among the SVs, splice variant 1 (SV1) possesses the greatest similarity to the full-length GHRH-R and remains functional by eliciting cAMP signaling and mitogenic activity upon GHRH stimulation...

Finasteride and dutasteride, synthetic 5α-reductase inhibitors (5ARIs) are recommended in many guidelines for the treatment of benign prostatic hyperplasia/lower urinary tract symptoms and alopecia despite a variety of side effects like sexual, neurological, psychiatric, endocrinological, metabolic and ophthalmological dysfunctions and the increased incidence of high grade prostate cancer. The sexual side effects are common during the use of the drug but in a small subgroup of patients, they can persist after stopping the drug...

PURPOSE: This review analyzed the top 100 most-cited thyroid eye disease (TED) papers. METHODS: In November 2022, Scopus was searched for the most highly cited TED works since inception. For each paper, journal of origin and impact factor, corresponding author country and specialty affiliation, citation count, publication year, database-affirmed study funding, and open-access status were extracted. RESULTS: A total of 76 primary and 24 secondary articles were published between 1969 and 2021 across 29 journals, with a median (range) of 186...

Pituitary apoplexy is a rare entity, which is characterized by severe neurological, ophthalmological, and endocrinological complications, with acute adrenal crisis being a major concern. The diagnosis of pituitary apoplexy is challenging, particularly in cases where it coexists with bacterial meningitis, leading to a diagnostic dilemma and delay in treatment. We report a case of a 23-year-old female diagnosed with pituitary apoplexy with concurrent bacterial meningitis.

PURPOSE: Congenital aniridia is a severe malformation of almost all eye segments. In addition, endocrinological, metabolic, and central nervous systems diseases may be present. In order to develop better treatment options for this rare disease, an aniridia center must be established. The purpose of this work is to summarize ophthalmic findings of aniridia subjects examined at the Department of Ophthalmology, Saarland University Medical Center in Homburg. METHODS: Our retrospective single-center study included patients who underwent a comprehensive ophthalmic examination through the head of the KiOLoN ("Kinderophthalmologie", Orthoptics, Low Vision and Neuroophthalmology) Unit of the department between June 2003 and January 2022...

BACKGROUND: Around 1.2 to 3.1% of thyroid malignancies are due to metastasis. Among them, cutaneous malignant melanomas constitute 4% of malignancy metastasized to the thyroid. Uveal melanoma is uncommon, and its metastasis to the thyroid has only rarely been reported. Hereby, we describe an unusual case of uveal melanoma metastasized to the thyroid and discuss the concept of correct diagnosis. Case Report . During a routine ophthalmological examination, an 86-year-old Caucasian female was found to have retinal detachment secondary to choroidal melanoma...

INTRODUCTION: Turner syndrome association with multi-organ system comorbidities highlights the need for effective implementation of follow-up guidelines. We aimed to assess the adequacy of care with international guidelines published in 2007 and 2017 and to describe the phenotype of patients. METHODS: In this multicenter retrospective descriptive cohort study, we collected growth and pubertal parameters, associated comorbidities, treatment, and karyotype in patients diagnosed at age <18 years between 1993 and 2022...

PURPOSE: Although Rathke cleft cysts (RCC) are benign lesions of the sellar region, recurrence is frequent after surgical treatment. Nuclear translocation of ß-catenin (NTßC), a key effector of the wnt-signaling pathway that is responsible for cell renewal, has been shown to act as a proto-oncogene and is considered to be a potential risk factor for increased recurrence in RCC. In this study, we analyzed a surgically treated cohort into patients with and without NTßC expression in order to identify clinical and imaging differences and further evaluate the risk of recurrence...

The COVID-19 pandemic has changed many aspects of people's lives, including not only individual social behavior, healthcare procedures, and altered physiological and pathophysiological responses. As a result, some medical studies may be influenced by one or more hidden factors brought about by the COVID-19 pandemic. Using the literature review method, we are briefly discussing the studies that are confounded by COVID-19 and facemask-induced partiality and how these factors can be further complicated with other confounding variables...

PURPOSE: Central Serous Chorioretinopathy (CSCR) is a prevalent ocular disease classified in the pachychoroidal spectrum with an elevated morbidity. Although the pathogenesis is yet unclear, mineralocorticoid-mediated pathways seem to be implicated. Primary hyperaldosteronism (PA) is a relatively frequent, albeit underdiagnosed, cause of hypertension, and has a specific therapy. A previous study assessed the prevalence of CSCR-like signs in a cohort of patients diagnosed with PA and found signs in seven out of thirteen PA patients...

Lymphocytic hypophysitis (LH) is a primary inflammatory disorder of the pituitary gland and infundibulum that commonly manifests in both mass effect and endocrinologic symptoms. Although the exact pathophysiology remains unclear, it has been increasingly linked to an autoimmune process. Complications arise by two separate mechanisms. Inflammation in the sella can lead to headaches and visual field defects. Pituitary inflammation and, chronically, fibrosis interfere with the gland's hormone-secreting capacity, often resulting in various endocrinopathies such as polyuria, polydipsia, amenorrhea, and others...

OBJECTIVE: To observe the distribution characteristics of peripheral blood inflammatory indexes and retinal macular area optical coherence tomography (OCT) imaging biomarkers in patients with diabetic retinopathy (DR) with or without diabetic nephropathy (DN), in order to seek clinical biomarkers that can predict the development of DR and DN. METHODS: A total of 169 inpatients with DR who visited the ophthalmology department of the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from October 2020 to June 2022 and had complete clinical data were collected, and the patients with DR were divided into two major groups, DR and DR/DN, according to whether they had DN, and then further divided into four subgroups, Non-proliferative DR(NPDR), proliferative DR(PDR), NPDR/DN and PDR/DN, according to the stage of DR...

PURPOSE: The aim of this study was to evaluate peripapillary, macular microvascular structure, and retinal nerve fiber layer (RNFL) thickness profile in children with Graves Ophthalmopathy (GO). MATERIAL AND METHODS: Thirty-six eyes of 18 children with GO were prospectively compared with 40 eyes of 20-age and sex-matched controls. The severity and activity of the disease were evaluated according to the criteria of the European Group on Graves' Ophthalmopathy (EUGOGO) and Clinical Activity Score (CAS)...

BACKGROUND: ChatGPT, a large language model, has shown good performance on physician certification examinations and medical consultations. However, its performance has not been examined in languages other than English or on nursing examinations. OBJECTIVE: We aimed to evaluate the performance of ChatGPT on the Japanese National Nurse Examinations. METHODS: We evaluated the percentages of correct answers provided by ChatGPT (GPT-3.5) for all questions on the Japanese National Nurse Examinations from 2019 to 2023, excluding inappropriate questions and those containing images...

Camurati-Engelmann disease (CED) causes bone pain, muscle weakness, and cranial nerve symptoms due to abnormal thickening of the long bones of the limbs and the cortex of the skull. The pathophysiology of CED is a gain-of-function variant of transforming growth factor beta 1 ( TGFB1 ). The ophthalmological symptoms of CED are usually caused by increased intracranial pressure and optic canal stenosis. Here, we report the case of a patient in whom prednisolone was effective against papilledema caused by CED. In this case, when papilledema was observed in both fundi, the patient showed increased bone pain, fever, and elevated CRP and ALP levels...

To analyze the perioperative course and clinical outcome of patients with large (lPA) and giant (gPA) pituitary adenoma who underwent endoscopic endonasal transsphenoidal surgery (EETS) using either two-dimensional (2D-E) or three-dimensional (3D-E) endoscopic systems. Single-center retrospective study of consecutive patients with lPA and gPA who underwent EETS between November 2008 and January 2023. LPA were defined as ≥ 3 cm and < 4 cm in diameter in at least one dimension and a volume of ≥ 10ccm; gPA were defined as larger than 4 cm in diameter and with a greater volume than 10ccm...

Blood urea nitrogen (BUN) is an indicator of renal function and catabolic status in human body. Diabetic retinopathy (DR) is a major microvascular complication of diabetes mellitus (DM) and a serious threat to the vision of diabetic patients. We included 426 type 2 diabetic patients who visited the endocrinology department of Guangdong Provincial People's Hospital and received an ophthalmology consultation from December 2017 to November 2018. The outcome was the probability of DR in participants. Multivariable logistics analysis was used to confirm the relationship between BUN and the probability of DR...
