Introduction: Sarcoidosis is a multisystem granulomatous disorder. It commonly causes mild hypercalcemia in up to 10–20% of the cases and renal involvement can be a feature. Presentation with severe symptomatic hypercalcaemia (>3.5 mmol/l) and acute kidney injury is rare. We present an interesting case.Case: A 58 year old female was referred to the emergency department by her general practitioner with a one month history of polyuria, generalised wea...

Introduction: Glycated haemoglobin (HbA1c) is used to measure glycaemic control in patients with diabetes, and accuracy depends on normal erythrocyte lifespan. Dapsone causes spuriously low HbA1c results by reducing erythrocyte lifespan through haemolysis and methaemoglobin formation, which interferes with the liquid-chromatography method used to measure HbA1c. Dapsone-induced haemolysis (DIH) is mostly reported in patients with glucose-6-phosphate dehydrogenase (G6PD) deficie...

Introduction: Hyponatraemia following surgery is usually due to a mismatch between fluid input and output peri- and post-operatively. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is another important cause of hyponatraemia, commonest cause being medications, and intrathoracic and intracranial infections and neoplasia. SIADH has been reported to occur after pituitary surgery but rarely after other types of surgery. We present a severe case of SIADH-related h...

Introduction: Idiopathic hypogonadotrophic hypogonadism (IHH) with normal sense of smell is a complex and rare disease entity characterised by insufficient gonadotropin releasing hormone (GnRH) neuronal action on an intact hypothalamo–pituitary–gonadal axis. IHH has an incidence of 1–10 in 100 000 live births with a variable mode of inheritance and five-fold male predominance. Gene mutations have been discovered of which 10–40% of the familial cases are due...

Objective: To investigate osteoporosis features in elder patients in Moscow populationMaterials and Methods: It was a retrospective study, during which we analyzed the data of 192 outpatients admitted to our Centre. In the focus of our attention was patients’ past medical history and T-criteria values assessed by DEXA-scan. The statistical analysis was performed using Prism 8 Version 8.0.1 (145). Statistically significant were differences with P...

Background and aim: The role of derangements of nitric oxide (NO) metabolism in the pathogenesis of complications of type 1 diabetes mellitus (T1D) is not sufficiently clear. There is little data on simultaneous measurements of NO metabolites nitrite and nitrate (NO2/NO3) in urine and serum in T1D. Data about the measurement of NO production by electronparamagnetic spectroscopy (EPR) in whole blood in T1D were never published. To fill this gap we have cha...

Context: Osmotic stimulus or stress results in release of vasopressin. Animal studies have shown that inflammatory parameters such as interleukin-6 (IL-6) and interleukin-8 (IL-8) increase in parallel, mainly in central brain regions. Whether osmotic stimulation leads to an inflammatory response in humans is unknown. We therefore investigated the influence of osmotic stimulation on the inflammatory system in healthy volunteers.Method: In this prospective...

Background: Metabolic syndrome (MetS) and peripheral endothelial dysfunction (PED) are both independently associated with an increased risk of cardiovascular disease (CVD). PED provides prognostic information beyond that provided by conventional risk factors. However, the association between MetS and PED remains uncertain. We evaluated the association between MetS and PED.Methods: We performed a retrospective analysis of patients who were referred to May...

Topicality: Thyroid nodules are detected by palpation in 4–8% of the adult population and in ultrasound in 10–41%. However, most of them (90%) are benign tumors and require monitoring. Indications for surgery are compression symptoms and/or hyperthyroidism, as well as cosmetic issues. One of the severe complications of the operation is intraoperative damage of the recurrent laryngeal nerve.Research objective: Minimize the risk of damage to the ...

Introduction: Hyponatremia is the most prevalent electrolyte disturbance in hospitalized patients. Seasonal variation with higher incidence of profound hyponatremia during summer months has been described for patients in the emergency department setting. Whether this observation is also true among medical inpatients is unknown. This study aimed at analyzing the seasonal incidence of hyponatremia as well as sex and age specific differences among medical inpatients.<p class=...
