Evaluation and follow-up of patients diagnosed with hypophysitis: a cohort study.

Objective: Primary hypophysitis might be challenging to diagnose, and there is a lack of evidence regarding optimal treatment strategies due to rarity of the disease. We aim to investigate the clinical features and compare the outcomes of different management strategies of primary hypophysitis in a large group of patients recruited on a nationwide basis.

Design: A retrospective observational study.

Subacute THYROiditis Related to SARS-CoV-2 VAccine and Covid-19 (THYROVAC Study): A Multicenter Nationwide Study.

Context: The aims of the study are to compare characteristics of subacute thyroiditis (SAT) related to different etiologies, and to identify predictors of recurrence of SAT and incident hypothyroidism.

Methods: This nationwide, multicenter, retrospective cohort study included 53 endocrinology centers in Turkey. The study participants were divided into either COVID-19-related SAT (Cov-SAT), SARS-CoV-2 vaccine-related SAT (Vac-SAT), or control SAT (Cont-SAT) groups.

Relationship between glycosylated hemoglobin and vitamin B12 deficiency anemia.

Objective: Previous studies showed that vitamin B12 deficiency anemia causes a false increase in glycosylated hemoglobin (HbA1c) and that HbA1c decreases with B12 treatment. However, no study has been conducted on how much an increase in hemoglobin (Hgb) level causes a decrease in HbA1c level after treatment.

Methods: The study included 37 patients who were not diagnosed with diabetes, did not use anti-diabetic drugs, were pre-diabetic according to HbA1c level, and were diagnosed with vitamin B12 deficiency anemia in the patient group and 40 healthy volunteers of similar age and gender characteristics in the control group.

A Hypothesis Regarding Neurosecretory Inhibition of Stress Mediators by Colchicine in Preventing Stress-Induced Familial Mediterranean Fever Attacks.

Familial Mediterranean fever (FMF) is a monogenic autoinflammatory disease characterized by recurrent episodes of fever and serositis. Colchicine (Col) has a crucial role in the prevention of amyloidosis and FMF attacks. The effect of Col on innate immune cells is based on the inhibition of the microtubule system.

Hypercalcemia in IgG4-related disease: coincidental or associated? Case based review.

Immunoglobulin (Ig) G4-related disease (IgG4RD) is a chronic autoimmune disorder characterized by dense lymphoplasmacytic infiltrations and fibrosis of storiform pattern. The most typical manifestations include major salivary or lacrimal gland involvement, autoimmune pancreatitis, and retroperitoneal fibrosis. While the increase in IgG4 is the typical feature of the disease, hypercalcemia has been rarely reported in IgG4RD so far, only one of these cases has been shown parathyroid gland involvement (isolated involvement).

Evaluation of hyperferritinemia causes in rheumatology practice: a retrospective, single-center experience.

Hyperferritinemia may develop due to various reasons such as inflammation, infection, or malignancy. The purpose of the study to explore the prevalence and to figure out the causes of general hyperferritinemia and extreme hyperferritinemia as detected through the ferritin measurements requested by the rheumatology department. Adult patients at the age of 18 years and older with at least one serum ferritin level measurement at or above 500 ng/mL as requested by the rheumatology department between January 2010 and December 2019 were evaluated retrospectively.

Cytopathology-histopathology correlation and the effect of nodule diameter on diagnostic performance in patients undergoing thyroid fine-needle aspiration biopsy.

Introduction: Although thyroid fine-needle aspiration biopsy (FNAB) is established to have a good overall sensitivity and specificity, various outcomes have been reported on its performance in large nodules. The aim of the study was to evaluate the diagnostic performance of FNAB and the effect of the nodule diameter on its diagnostic performance.

Materials And Methods: The outcomes of a total of 7319 patients who underwent FNAB over the course of 5 years were analyzed retrospectively and 648 patients who had undergone post-FNAB thyroidectomy or lobectomy were included in the study.

Familial Mediterranean fever: the molecular pathways from stress exposure to attacks.

FMF is an autoinflammatory disease characterized by recurrent attacks and increased IL-1 synthesis owing to activation of the pyrin inflammasome. Although knowledge of the mechanisms leading to the activation of pyrin inflammasome is increasing, it is still unknown why the disease is characterized by attack. The emergence of FMF attacks after emotional stress and the induction of attacks with metaraminol in previous decades suggested that stress-induced sympathoadrenal system activation might play a role in inflammasome activation and triggering attacks.

The acromegaly registry of ten different centers in Turkey.

Objectives: To describe biochemical and clinical features, and therapeutic outcomes of acromegaly patients in Turkey.

Methods: Retrospective multicenter epidemiological study of 547 patients followed in 10 centers of the Turkish Acromegaly registry.

Results: A total of 547 acromegaly patients (55% female) with a median age of 41 was included in this study.

Hyperkalemia in type 4 renal tubular acidosis associated with systemic lupus erythematosus.

Renal tubular acidosis (RTA) is a normal anion gap metabolic acidosis that manifests with insufficiency of hydrogen ion excretion or bicarbonate (HCO) reuptake as a result of renal tubular dysfunction independent of glomerular filtration rate. Hypokalemic RTA subtypes co-existing with autoimmune diseases particularly appear in Sjogren's syndrome, but rarely in systemic lupus erythematosus (SLE). Type 4 RTA associated with hyperkalemia is very rare during the course of SLE and hence has been scarcely reported in the literature.

What is the optimal time for measuring glucose concentration to detect steroid-induced hyperglycemia in patients with rheumatic diseases?

Objective: Corticosteroids may cause hyperglycemia and diabetes mellitus (DM). Development of DM during long-term steroid use has been well studied; however, data regarding the short-term effects of steroid therapy are scarce. In this study, we aimed to detect the actual time of short-term steroid-induced hyperglycemia in patients without previous impaired glucose metabolism, and the ideal time (which day and in relation to meals) of glucose measurement.

Parathyroid hormone in washout fluid seems to be superior to cytology for localization of the lesion in MIBI-negative patients with primary hyperparathyroidism.

Background/aim: Primary hyperparathyroidism (PHPT) is characterized by increased calcium (Ca) and parathyroid hormone (PTH) levels. Surgical removal of the culprit hyperfunctioning parathyroid gland is the preferred treatment. In this study, we aimed to determine whether PTH-washout or cytological examination of suspicious lesions was superior in MIBI-negative patients diagnosed with PHPT.

Evaluation of Incidental Thyroid Nodules in Cancer Patients.

Objective: Frequency of thyroid cancer in incidental thyroid nodules identified by imaging techniques in cancer patients is higher than that in the normal population. In the retrospective study, we have both investigated the incidence of thyroid cancer in incidentally identified nodules and compared the imaging techniques to determine whether there is any difference between them in detection of malign nodules.

Methods: A total of 7319 patients who underwent thyroid fine-needle aspiration biopsy (FNAB) were included in the study.

Which type 2 diabetes mellitus patients should be screened for subclinical Cushing's syndrome?

Objective: Diabetes or impaired glucose tolerance are common in patients with Cushing's syndrome (CS). In this study we investigated the incidence of subclinical Cushing's syndrome (SCS) in type 2 diabetic patients with poor and good metabolic control and the relationship between blood glucose and cortisol levels.

Design: A total of 400 type 2 diabetes mellitus (T2DM) patients (Group A, HbA1c ≥8%, n=250; Group B, HbA1c ≤6.

ASSESSMENT OF DIASTOLIC DYSFUNCTION, ARTERIAL STIFFNESS, AND CAROTID INTIMA-MEDIA THICKNESS IN PATIENTS WITH ACROMEGALY.

Objective: Early diagnosis and treatment of cardiovascular diseases, the most frequent cause of morbidity and mortality in acromegaly, may be an efficient approach to extending the lifespan of affected patients. Therefore, it is crucial to determine any cardiovascular diseases in the subclinical period. The study objectives were to determine markers of subclinical atherosclerosis and asses heart structure and function.

A novel truncating AIP mutation, p.W279*, in a familial isolated pituitary adenoma (FIPA) kindred.

Familial isolated pituitary adenomas (FIPA) constitute 2-3% of pituitary tumours. AIP is the most commonly mutated gene in FIPA. We herein report a novel germline mutation of the AIP gene in a family with FIPA.

Adrenal crisis while on high-dose steroid treatment: what rheumatologist should consider?

Steroid treatment is commonly recommended for autoimmune disorders in rheumatology practice. While adrenal crisis may occur upon existence of an inducing factor in patients with known or unknown adrenal insufficiency as well as in those with a suppressed hypothalamic-pituitary-adrenal (HPA) axis due to chronic steroid use, addisonian crisis rarely develops in patients on supraphysiological doses of steroid and, when emerged, it might be very difficult to recognize. Here, we present a patient who developed adrenal crisis while receiving high-dose methylprednisolone treatment due to retroperitoneal fibrosis and we also discuss possible mechanisms with a brief literature review.

Markers of Subclinical Cardiovascular Disease in Nonfunctional Adrenal Incidentaloma Patients without Traditional Cardiovascular Risk Factors.

Data regarding cardiovascular risk in patients with non-functional adrenal incidentaloma (NFAI) are limited. The objectives of this study are to investigate markers of subclinical cardiovascular disease like carotid intima media thickness (CIMT), pulse wave velocity (PWV), augmentation index (AIx), soluble CD40 ligand (sCD40L) and leptin levels in NFAI patients without traditional cardiovascular risk factors and healthy control group. This study involved 35 patients with NFAI (11 males, 24 females; mean age, 52.

An unusual case in endocrinology practice: Suture granuloma.

Objective: Suture granuloma, the rare complication of thyroidectomy, results from the use of nonabsorbable suture materials. Despite its typical ultrasound images and benign course, it carries utmost importance in the diff erential diagnosis of lymph nodes, recurrent nodules, and recurrence in the case of thyroid cancers. Subject and Results.

Parathyroidectomy in asymptomatic primary hyperparathyroidism reduces carotid intima-media thickness and arterial stiffness.

Objective: Although an International Workshop has suggested that cardiovascular assessment in asymptomatic primary hyperparathyroidism (PHPT) patients is not necessary, improvements in risk factors of subclinical atherosclerosis have been shown following parathyroidectomy. The objectives of this study were to determine whether parathyroidectomy in asymptomatic PHPT patients causes any change in carotid intima-media thickness (CIMT), arterial stiffness [pulse wave velocity (PWV)] and soluble CD40 ligand (sCD40L) levels.

Design: Prospective study evaluating female patients diagnosed with asymptomatic PHPT in a single centre over a 6-month period.

Subcutaneous NPH Insulin for Severe Hypertriglyceridemia in a Pregnant Patient with Type V Hyperlipoproteinemia: a Case Report.

An increase in triglyceride levels in familial hyperlipidemia during pregnancy has been reported. Severe hypertriglyceridemia can lead to complications such as acute pancreatitis, preeclampsia, maternal and fetal complications. Because of the teratogenic effects associated with fibrate therapy in pregnancy, alternative treatment strategies such as insulin as a rapid and potent activator of lipoprotein lipase are required during pregnancy.
