Abstract Purpose Repeat surgery in patients with primary hyperparathyroidism (pHPT) is associated with an increased risk of complications and failure. This stresses the need for optimized strategies to accurately localize a parathyroid adenoma before repeat surgery is performed. However, evidence on the extent of required diagnostics for a structured approach is sparse. Methods A retrospective single-center evaluation of 28 patients with an indication for surgery due to pHPT and previous thyroid or parathyroid surgery was performed. Diagnostic workup, surgical approach, and outcome in terms of complications and successful removement of parathyroid adenoma with biochemical cure were evaluated. Results Neck ultrasound, sestamibi scintigraphy, C11-methionine PET-CT, and selective parathyroid hormone venous sampling, but not MRI imaging, effectively detected the presence of a parathyroid adenoma with high positive predictive values. Biochemical cure was revealed by normalization of calcium and parathormone levels 24–48h after surgery and was achieved in 26/28 patients (92.9%) with an overall low rate of complications. Concordant localization by at least two diagnostic modalities enabled focused surgery with success rates of 100%, whereas inconclusive localization significantly increased the rate of bilateral explorations and significantly reduced the rate of biochemical cure to 80%. Conclusion These findings suggest that two concordant diagnostic modalities are sufficient to accurately localize parathyroid adenoma before repeat surgery for pHPT. In cases of poor localization, extended diagnostic procedures are warranted to enhance surgical success rates. We suggest an algorithm for better orientation when repeat surgery is intended in patients with pHPT.

The article is devoted to one of the actual medical and social problems — primary hyperparathyroidism, the late diagnosis of which leads to the development of severe complications and an increased risk of premature death. Unlike developed countries, where 80% of cases are represented by mild forms of the disease, in the Russian Federation this indicator does not exceed 30%, while 70% are manifest forms. Widespread awareness of doctors of various specialties in the diagnosis of parathyroid adenoma is necessary for the timely detection of the disease. The article reflects the main stages of the study of the disease, the pathogenesis of the clinical manifestations of primary hyperparathyroidism, the classic symptoms of which are changes in the target organs of the parathyroid hormone — bone tissue, urinary system and gastrointestinal tract, is considered. Bone disorders are the most common manifestation of hyperparathyroidism and are characterized by increased bone metabolism with a progressive decrease in bone mineral density. Typical changes in the kidneys include nephrolithiasis and nephrocalcinosis, causing the formation of renal failure. Gastrointestinal signs of hyperparathyroidism are erosion and ulcers of the stomach and duodenum, prone to bleeding, recurrent pancreatitis. Diagnosis of the disease is based on laboratory results, characterized by elevated levels of calcium and parathyroid hormone in the blood. Visualization of the paradenomas in most cases is provided by ultrasound and scintigraphy. Removal of parathyroid adenoma is the most effective treatment. A clinical case of a severe form of the disease is presented, indicating an urgent need to take measures to solve the problem of primary hyperparathyroidism.

Summary Primary hyperparathyroidism requires a surgical approach to achieve a long-term cure. However, post-surgical recurrence significantly complicates the management of this condition. A number of causes for recurrent disease are well understood and several diagnostic modalities exist to localise the culprit parathyroid adenoma although none of them is efficacious in localisation of the recurrent lesion. In this case report, we highlight a novel causative mechanism and describe a unique diagnostic sequence that enabled curative treatment to be delivered. Learning points In the case described herein, we describe a novel location for a parathyroid adenoma causing recurrent PHPT. The case elucidates well the difficulties presented by such cases in terms of surgical planning and show the utility of PVS in such cases. Based on this case, we make the following recommendations: Meticulous care must be taken to prevent seeding of adenomatous tissue during primary excision. To consider the use of PVS in patients with discordant imaging in the setting of recurrent/persistent PHPT as a method to localise the causative adenoma. Same day PVS and surgery is a viable option for patients who either represent an anaesthetic risk or who are extremely anxious about the prospect of two separate procedures. Disordered calcium homeostasis is an important but forgotten cause of dysphagia which can be extremely debilitating for affected patients.

High Index Of Suspicion

Parathyroid glands, minute endocrine glands, located in posterior aspect of thyroid glands secrete parathormone which plays an important role in maintaining calcium homeostasis in the body. The superior and inferior parathyroid glands originate from the 4th and 3rd branchial pouches respectively and migrate to occupy their normal positions in relation to the thyroid gland.1 Hyperparathyroidism is defined as hyper functioning of parathyroid gland and can be primary, secondary or tertiary. Primary hyperparathyroidism is due to parathyroid gland proliferative disorders which include parathyroid adenoma, parathyroid hyperplasia, parathyroid carcinoma or in association with other conditions in MEN syndrome. In more than 90 % patients, primary hyperparathyroidism is caused by a single parathyroid adenoma. Very rarely double parathyroid adenomas are seen. Secondary Hyperparathyroidism is caused in response to any chronic hypocalcaemic conditions like renal failure, gastrointestinal malabsorption, dietary rickets & drugs, like phenytoin, phenobarbital & laxative. Prolonged secondary hyperparathyroidism leads to tertiary hyperparathyroidism due to autonomous secretion. The clinical presentation of hyperparathyroidism is classically described as kidney stones, abdominal groans, painful bones, psychic moans, and fatigue overtones. In the initial course of the disease, the patients present with vague symptoms of fatigue, muscle and joint pain, frequent urination, nausea, constipation, and decreased appetite. If high index of suspicion is maintained, they can be conveniently diagnosed by routine blood tests which show increased calcium levels. However, in India still majority of people are diagnosed when they present with palpable neck mass, skeletal manifestations or deranged renal function. We hereby present 5 cases of parathyroid adenoma managed at our centre over a period of 2 years. P

The volume of parathyroid adenoma is related to presurgical PTH and 25OH-D3, but not calcium levels at patients with primary hyperparathyroidism

Abstract Objective: The aim of this meta-analysis was to investigate the association between malnutrition assessed by the controlling nutritional status (CONUT) score and all-cause mortality in patients with heart failure. Design: Systematic review and meta-analysis. Settings: A comprehensively literature search of PubMed and Embase databases was performed until 30 November 2020. Studies reporting the utility of CONUT score in prediction of all-cause mortality among patients with heart failure were eligible. Patients with a CONUT score ≥2 are grouped as malnourished. Predictive values of the CONUT score were summarized by pooling the multivariable-adjusted risk ratios (RR) with 95 % CI for the malnourished v. normal nutritional status or per point CONUT score increase. Participants: Ten studies involving 5196 patients with heart failure. Results: Malnourished patients with heart failure conferred a higher risk of all-cause mortality (RR 1·92; 95 % CI 1·58, 2·34) compared with the normal nutritional status. Subgroup analysis showed the malnourished patients with heart failure had an increased risk of in-hospital mortality (RR 1·78; 95 % CI 1·29, 2·46) and follow-up mortality (RR 2·01; 95 % CI 1·58, 2·57). Moreover, per point increase in CONUT score significantly increased 16% risk of all-cause mortality during the follow-up. Conclusions: Malnutrition defined by the CONUT score is an independent predictor of all-cause mortality in patients with heart failure. Assessment of nutritional status using CONUT score would be helpful for improving risk stratification of heart failure.
