Synchronous Antithyroid Drug-Induced Agranulocytosis and Fournier Gangrene
2018
ABSTRACT: Objective: Antithyroid drugs (ATDs) such as thioimidazoles (e.g., methimazole, also called thiamazole, and carbimazole) and propylthiouracil are commonly used for the treatment of hyperthyroidism. A life-threatening reaction is agranulocytosis with an incidence of 0.1 to 0.5%. There are very few cases in the literature showing that the intake of ATDs finally led to sepsis with accompanying tissue necrosis.Methods: We present an unusual case of severe symptomatic agranulocytosis with sudden development of Fournier gangrene in a patient who was treated with ATDs for hyperthyroidism due to Graves disease.Results: A 69-year-old female was referred to our hospital with fever and a sore…
Phenotypic variation in hyperandrogenic women influences the findings of abnormal metabolic and cardiovascular risk parameters.
2005
In hyperandrogenic women, several phenotypes may be observed. This includes women with classic polycystic ovary syndrome (C-PCOS), those with ovulatory (OV) PCOS, and women with idiopathic hyperandrogenism (IHA), which occurs in women with normal ovaries. Where other causes have been excluded, we categorized 290 hyperandrogenic women who were seen consecutively for this complaint between 1993 and 2004 into these three subgroups. The aim was to compare the prevalence of obesity, insulin resistance, and dyslipidemia as well as increases in C-reactive protein and homocysteine in these different phenotypes with age-matched ovulatory controls of normal weight (n = 85) and others matched for body…
Transient hypothyroidism during lactation arrests myelination in the anterior commissure of rats. A magnetic resonance image and electron microscope …
2018
Thyroid hormone deficiency at early postnatal ages affects the cytoarchitecture and function of neocortical and telencephalic limbic areas, leading to impaired associative memory and in a wide spectrum of neurological and mental diseases. Neocortical areas project interhemispheric axons mostly through the corpus callosum and to a lesser extent through the anterior commissure (AC), while limbic areas mostly project through the AC and hippocampal commissures. Functional magnetic resonance data from children with late diagnosed congenital hypothyroidism and abnormal verbal memory processing, suggest altered ipsilateral and contralateral telencephalic connections. Gestational hypothyroidism aff…
Specific mutations of the RET proto-oncogene are related to disease phenotype in MEN 2A and FMTC.
1994
We have analysed 118 families with inherited medullary thyroid carcinoma (MTC) for mutations of the RET proto-oncogene. These included cases of multiple endocrine neoplasia types 2A (MEN 2A) and 2B (MEN 2B) and familial MTC (FMTC). Mutations at one of 5 cysteines in the extracellular domain were found in 97% of patients with MEN 2A and 86% with FMTC but not in MEN 2B patients or normal controls. 84% of the MEN2A mutations affected codon 634. MEN 2A patients with a Cys634 to Arg substitution had a greater risk of developing parathyroid disease than those with other codon 634 mutations. Our data show a strong correlation between disease phenotype and the nature and position of the RET mutatio…
Gestational diabetes and the metabolic syndrome: Can obesity and small, dense low density lipoproteins be key mediators of this association?
2013
Gestational diabetes mellitus (GDM) represents a condition of glucose intolerance with first appearance or recognition at the time of a pregnancy, associated with an inadequate pancreatic response to the advanced insulin resistance of the later stages of pregnancy, and accompanied by enhancing β-cell mass and secretion of insulin. Women who had GDM exhibit a higher risk for later advent of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). Additionally, previous GDM has been proposed as independently correlated with higher risk for development of atherosclerosis in a healthy population, similar to the metabolic syndrome (MetS) and independently of the presence of established…
The importance of diagnosing the Polycystic Ovary Syndrome
2000
The polycystic ovary syndrome (PCOS) is an extremely common disorder that occurs in 4% to 7% of women of reproductive age. Although PCOS is known to be associated with reproductive morbidity and increased risk for endometrial cancer, diagnosis is especially important because PCOS is now thought to increase metabolic and cardiovascular risks. These risks are strongly linked to insulin resistance and are compounded by the common occurrence of obesity, although insulin resistance and its associated risks are also present in nonobese women with PCOS. Women with PCOS are at increased risk for impaired glucose tolerance, type 2 diabetes mellitus, and hypertension. Cardiovascular disease is believ…
Regulated Proteolysis of RAGE and AβPP as Possible Link Between Type 2 Diabetes Mellitus and Alzheimer's Disease
2009
Epidemiological studies have linked type 2 diabetes mellitus (T2DM) with an increased risk of developing Alzheimer's disease (AD). In T2DM, the elevated blood glucose level promotes formation of advanced glycation end products (AGEs). The receptor for AGEs (RAGE) is a type I membrane-protein and is also able to import amyloid-beta (Abeta) from the blood across the blood-brain-barrier into the brain. Oligomeric Abeta peptides disturb synaptic function in the brain and are believed to contribute to the development of AD. Abeta peptides are released from the amyloid-beta protein precursor (AbetaPP) after sequential proteolysis by beta- and gamma-secretases but alpha-secretase-mediated cleavage…
ONE-TROCAR VIDEO-ASSISTED STRIPPING TECHNIQUE FOR USE IN THE TREATMENT OF LARGE OVARIAN CYSTS IN INFANTS
2010
Abstract Background Management of ovarian cysts in infants is controversial; it can be conservative or surgical, and the management is determined by the cyst's size and sonographic features. Methods A surgical approach using a 10-mm umbilically placed operative laparoscope was taken in 3 female infants with antenatally diagnosed large, simple ovarian cysts. The contents of the cysts were partially aspirated and the cyst walls were stripped off the remaining ovarian parenchyma. No intraoperative or postoperative complications were recorded. Conclusions The one-trocar video-assisted stripping technique for large ovarian cysts in infants appears to be an ovarian-tissue-preserving procedure, an…
Determinants of elevated carbohydrate antigen 125 in patients with severe symptomatic aortic valve stenosis referred for transcatheter aortic valve i…
2018
Elevated carbohydrate antigen 125 (CA125) predicts adverse outcome after transcatheter aortic valve implantation (TAVI). While known underlying pathophysiological mechanisms of elevated CA125 include serosal effusions and inflammatory stimuli, clinical determinants associated with elevated CA125 in patients referred for TAVI remain unknown. Therefore, we investigated clinical, laboratory and echocardiographic determinants of elevated CA125 in patients with severe aortic valve stenosis referred for TAVI.This study includes 650 patients with severe aortic stenosis referred for TAVI. Baseline CA125 was determined by an immunoassay and dichotomized (elevated versus normal) based on the manufact…
Effects of empagliflozin on CA125 trajectory in patients with chronic congestive heart failure
2021
INTRODUCTION: We aimed to evaluate the trajectory of two surrogates of fluid overload -antigen carbohydrate 125 (CA125) and amino-terminal pro-brain natriuretic peptide (NT-proBNP)- after the addition of oral empagliflozin to usual care in a cohort of patients with chronic heart failure (CHF) and type 2 diabetes (T2D). METHODS AND RESULTS: From October 2015 to February 2019, 60 ambulatory patients with CHF and T2D were retrospectively included. The primary endpoint was to assess the longitudinal trajectory of plasma levels of CA125 and NT-proBNP after empagliflozin initiation. Changes in quantitative variables were evaluated using linear mixed regression. Median CA125 and NT-proBNP at basel…
