Different treatment strategies in primary hyperparathyroidism during pregnancy.

Purpose: Primary hyperparathyroidism (PHPT) in pregnancy is rare enough and can be unrecognized because of nonspecific symptoms in most cases, but life-threatening complications for mother, fetus and neonate also occurs. PHPT requires frequent monitoring of the mother and fetus by a multidisciplinary team. Diagnostics and treatment approaches are limited and require individual risk-benefit assessment.

The Russian Registry of Chronic Hypoparathyroidism.

Introduction: Chronic hypoparathyroidism is a relatively rare disease associated with multicomponent medical therapy and various complications. The analysis of large databases of patients with chronic hypoparathyroidism is a necessary tool to enhance quality of medical care, as well as to determine the optimal clinical and therapeutic approaches, and prognostic markers of the disease.

The Aim: of this study is to estimate the clinical and biochemical profile, long-term complications, medical therapy and disease control of the patients with chronic postsurgical and non-surgical hypoparathyroidism.

Serum circulating miRNA-342-3p as a potential diagnostic biomarker in parathyroid carcinomas: A pilot study.

Objective: To compare the serum miRNA expression profiles between patients with benign and malignant parathyroid tumours.

Background: Despite recent advances in molecular biology, a histological tissue biopsy is still the method of choice used to diagnose most cancers. The preoperative cytology is not an applicable method for diagnosis of parathyroid cancer (PC); therefore, huge interest exists in terms of finding alternative methodologies to seek specific cancer biomarkers.

[Dynamic changes of renin-angiotensin-aldosterone system parameters after surgery of primary hyperparathyroidism].

Aim: To study an activity of the Renin-Angiotensin-Aldosterone System (RAAS) components in patients with primary hyperparathyroidism (PHPT) before and after parathyroidectomy (PTE).

Materials And Methods: A comparative study of patients with PHPT and control group. The first stage of the study included 56 patients with PHPT (group 1) before and on the third day after PTE.

Denosumab for management of severe hypercalcemia in primary hyperparathyroidism.

Hypercalcemic crisis is a severe but rare complication of primary hyperparathyroidism (PHPT), and data on denosumab treatment of patients with this disease is still very limited. The aim of this paper is to investigate the hypocalcemic effect of denosumab in PHPT patients with severe hypercalcemia when surgery should be delayed or is impossible for some reasons. We performed a retrospective study of 10 patients.

[Primary hyperparathyroidism in Russia according to the registry].

Background: There are no large-scale epidemiological studies on primary hyperparathyroidism (PHPT) in Russia. The high prevalence of the disease, the high risk of disability and death in this cohort of patients requires the study of the epidemiological and clinical structure of PHPT to determine the extent of medical care.

Aim: Evaluate the frequency of PHPT detection and characterize its clinical forms in Russia using an online registry.

Adrenocorticotropic hormone-producing pheochromocytoma: A case report.

Introduction: Cases of ectopic production of adrenocorticotropic hormone are considerably rare, but persistent in clinical practice. Extremely rare cases of ectopic production, such as via pheochromocytoma secretion, require special clinical attention and prior knowledge. It is important to understand the diagnostic algorithm for identifying ectopic sources of adrenocorticotropic hormone production.

[Surgical treatment of ACTH-ectopic syndrome].

ACTH-ectopic syndrome is a severe, multiple-symptom disease characterized by secretion of adrenocorticotropic hormone (ACTH) by ectopic tumor, increased release of adrenal cortical hormones and clinical picture of hypercorticism. Diagnosis and treatment of ACTH-ectopic syndrome is still difficult problem despite the achievements of modern medicine. There are several unresolved issues including optimal diagnostic algorithm, indications for various surgical procedures and their optimal dates.

Optimization of Eva Green real-time mPCR for differentiating C. jejuni/coli directly from feces.

Objective: To develop and optimize a rapid molecular method for diagnosing campylobacteriosis directly from a clinical fecal sample and at the same time for determining the most common causing agents - C. jejuni/coli.

Materials And Methods: 38 clinical fecal samples from hospitalized patients with diarrheal syndrome were tested using a rapid immunochromatographic test.

Multiplex PCR Assay for Identifi cation and Differentiation of Campylobacter jejuni and Campylobacter coli Isolates.

Introduction: Campylobacter spp. are important causative agents of gastrointestinal infections in humans. The most frequently isolated strains of this bacterial genus are Campylobacter jejuni and Campylobacter coli.
