Bitches with dystocia most often present with clinical signs of uterine inertia (UI). The aetiology of myometrial dysfunction in most of these cases is still not elucidated. We compared blood ionized calcium (iCa) and glucose concentrations in bitches diagnosed with primary UI (PUI, n = 14), secondary UI (SUI, n = 6) or obstructive dystocia (OD, n = 6), and we described their haematology profiles. Bitches diagnosed with UI had a patent birth canal and delivered no puppies yet (PUI) or only part of the whole litter (SUI)...

We report a case of severe generalised muscle weakness in a 66-year-old man who underwent revision of left knee arthroplasty. On postoperative day 1, he developed non-focal muscle weakness and shortness of breath which progressed over a 6-hour period. Serum phosphorus level was severely low at 0.5 mg/dL, along with mild degree of hypokalaemia, hypocalcaemia and hypomagnesaemia. His symptoms completely resolved after emergent phosphorus replacement. The authors believe this case is of educational interest to physicians as generalised muscle weakness is an uncommon presentation of severe hypophosphataemia...

BACKGROUND: Multiple myeloma is characterised by monoclonal paraprotein production and osteolytic lesions, commonly leading to skeletal-related events (spinal cord compression, pathological fracture, or surgery or radiotherapy to affected bone). Denosumab, a monoclonal antibody targeting RANKL, reduces skeletal-related events associated with bone lesions or metastases in patients with advanced solid tumours. This study aimed to assess the efficacy and safety of denosumab compared with zoledronic acid for the prevention of skeletal-related events in patients with newly diagnosed multiple myeloma...

OBJECTIVES: To investigate whether saliva formulations with reduced calcium (Ca) and inorganic phosphorous (Pi) concentration would affect dental erosion caused by hydrochloric acid (HCl). METHODS: Enamel and root dentine bovine slabs were embedded, polished and measured for surface Knoop microhardness (SMH). After reference areas were created, specimens were exposed to HCl solution (0.01M; pH 2; 120s) and immersed in artificial salivas (6h) containing three different Ca/Pi concentrations (n=15), which simulate serum conditions of normo-, mild- or severe hypocalcaemia...

BACKGROUND: Hypoparathyroidism, the most common complication after thyroid surgery, leads to hypocalcaemia and significant medical problems. An RCT was undertaken to determine whether intraoperative parathyroid gland angiography with indocyanine green (ICG) could predict postoperative hypoparathyroidism, and obviate the need for systematic blood tests and oral calcium supplementation. METHODS: Between September 2014 and February 2016, patients who had at least one well perfused parathyroid gland on ICG angiography were randomized to receive standard follow-up (measurement of calcium and parathyroid hormone (PTH) on postoperative day (POD) 1 and systematic supplementation with calcium and vitamin D; control group) or no supplementation and no blood test on POD 1 (intervention group)...

Brugada phenocopies (BrPs) are clinical entities that differ in etiology from true congenital Brugada syndrome but have identical electrocardiographic (ECG) patterns. Hyperkalemia is known to be one of the causes of BrP. The aim of this study was to determine the clinical characteristics and evolution of hyperkalemia-induced BrP. Data from 27 cases of hyperkalemia-induced BrP were collected from the International Registry at Data were extracted from publications. Of the 27 patients included in the analysis, 18 (67%) were male; mean age was 53 ± 15 years (range 31 to 89)...

AIMS: To determine the effects of oral Ca bolus administration in the early postpartum period of cows on milk yield and composition, blood metabolites, early-lactation health status, and reproductive performance. METHODS: Multiparous Holstein dry cows with a mean parity of 3.1 (SD 0.35) were fed a diet with a positive dietary cation-anion difference (DCAD) prior to calving. They were randomly assigned to receive no treatment (Control; n=33) or two oral Ca boluses (n=33, 45 g of Ca per bolus); one was administered after calving (Day 0) and the second 24 hours (± 30 minutes) later...

This case report describes an individual with brain calcifications, cognitive decline, motor dysfunction, and hypocalcaemia. Exome sequencing revealed a previously reported variant in the CASR gene and a variant of uncertain significance in PDGFRB. The clinical phenotype is likely explained by the CASR variant, but we discuss how the PDGFRB variant could also participate in the phenotype.

BACKGROUND: Osteoporosis is highly prevalent in the heart and lung transplant population. Given high rates of concurrent renal impairment, there is increasing use of denosumab in this population. However, denosumab may be associated hypocalcaemia, particularly in patients with chronic kidney disease (CKD). AIM: This study sought to explore the risk of hypocalcaemia in a heart and lung transplant cohort prescribed denosumab for osteoporosis. METHODS: We performed a retrospective database review of all surviving heart and lung transplant recipients who had received denosumab for osteoporosis between January 2012 and November 2015...

The UK Registry of Endocrine and Thyroid Surgeons (UKRETS) has been operated by the British Association of Endocrine and Thyroid Surgeons (BAETS) and Dendrite Clinical Systems Ltd. in a web-based electronic format since 2004. Data on over 90,000 endocrine procedures have been collected to date. Analysis of those cases undergoing bilateral thyroid resections in the interval July 2010 to June 2015 demonstrates that hypocalcaemia remains the commonest complication of thyroid surgery. After first-time total thyroidectomy, 23...

Hypocalcaemia following thyroid surgery is common and is associated with significant short and long term morbidity. Damage to or devascularisation of parathyroid glands is the predominant underlying mechanism; although other factors such as hungry bone syndrome may occasionally contribute to it in the immediate post-operative period. The reported incidence of post-surgical hypocalcaemia and/or hypoparathyroidism (PoSH) varies significantly in the literature; the variation thought to be at least partly due to differences in the definitions used...
