Abstract
Hypothyroidism is a highly prevalent endocrine complication in chronic kidney disease (CKD) patients. A large body of evidence has shown that there is a bidirectional relationship between thyroid dysfunction and kidney disease, yet there are many remaining gaps in knowledge in regards to the clinical management of CKD patients with hypothyroidism, including those receiving hemodialysis and peritoneal dialysis. Given that hypothyroidism has been associated with many deleterious outcomes including a higher risk of (1) mortality, (2) cardiovascular disease, (3) impaired health-related quality of life, and (4) altered body composition in both non-CKD and CKD patients, future research is needed to establish the appropriate screening, diagnosis, and treatment approaches in these populations.

Abstract
PURPOSE OF REVIEW Hypothyroidism is a highly prevalent endocrine disorder in the end-stage renal disease (ESRD) population, yet many cases may remain latent and undiagnosed. RECENT FINDINGS Epidemiologic data show that there is a nearly five-fold higher prevalence of hypothyroidism in advanced chronic kidney disease (CKD) patients vs. those without CKD. Given that the metabolism, degradation, and excretion of thyroid hormone and its metabolites, as well as the regulation of the hypothalamic-pituitary-thyroid axis may be altered in ESRD, certain considerations should be made when interpreting thyroid functional tests in these patients. Growing evidence shows that hypothyroidism and other thyroid functional test derangements are associated with higher risk of cardiovascular disease, worse patient-centered outcomes, and survival in the advanced CKD population, including those with ESRD. Although limited data examining treatment of hypothyroidism suggests benefit, further studies of the efficacy and safety of thyroid hormone supplementation, including clinical trials and rigorous longitudinal observational studies are needed to inform the management of thyroid dysfunction in CKD. SUMMARY Given the high burden of hypothyroidism in ESRD patients, and potential ill effects on their cardiovascular health, patient-centered outcomes, and survival, further research is needed to inform the optimal management of thyroid dysfunction in this population.

Abstract
PURPOSE OF REVIEW Hypothyroidism is highly prevalent in chronic kidney disease (CKD) patients, including those receiving dialysis. This review examines potential mechanistic links between thyroid and kidney disease; current evidence for hypothyroidism as a risk factor for de novo CKD and CKD progression; and studies of thyroid functional disorders, cardiovascular disease, and death in the CKD population. RECENT FINDINGS Epidemiologic data have demonstrated an incrementally higher prevalence of hypothyroidism with increasing severity of kidney dysfunction. Various thyroid functional test abnormalities are also commonly observed in CKD due to alterations in thyroid hormone synthesis, metabolism, and regulation. Although the mechanistic link between thyroid and kidney disease remains unclear, observational studies suggest that hypothyroidism is associated with abnormal kidney structure and function. Previously thought to be a physiologic adaptation, recent studies show that hypothyroidism is associated with higher risk of cardiovascular disease and death in CKD. SUMMARY A growing body of evidence suggests that hypothyroidism is a risk factor for incident CKD, CKD progression, and higher death risk in kidney disease patients. Rigorous studies are needed to determine the impact of thyroid hormone replacement upon kidney disease progression, cardiovascular disease, and mortality, which may shed light onto the causal implications of hypothyroidism in CKD.

Abstract
Iodide mumps, or contrast-induced acute sialadenitis, is characterised by rapid, painless enlargement of the salivary glands, following the use of iodinated contrast dye. The underlying mechanism of this adverse reaction is not completely understood. It could be due to an idiosyncratic reaction or related to deposition of iodide in the ductal systems of the salivary glands causing blockage and inflammation. With increasing renal dysfunction, the elimination half-life of the iodine-containing contrast dye gets prolonged. The course of iodine-induced sialadenitis is usually benign, and rapid resolution of symptoms is expected without definite treatment. The symptomatic management includes treatment with a parenteral non-steroidal anti-inflammatory drug (NSAID), steroids and dialysis. However, the role of steroids has been found to be controversial in previously published case reports. Pancreatic mumps and transient thyroid dysfunction were also reported in patients following iodinated contrast administration; the aetiology of this is thought to be similar to iodide-induced sialadenitis.

Abstract
Iodide mumps is an uncommon condition induced by iodide-containing contrast. We present the first reported case of iodide mumps in mainland China, which occurred after carotid artery intervention.The patient, a 65-year-old Chinese male, had a history of dizziness, hypertension, diabetes, and right arm weakness. He had no history of allergies and had never previously received iodide-containing contrast. The patient's kidney function and other laboratory findings were normal. He underwent stenting of the left internal carotid artery (LICA) opening and received approximately 250 mL of a nonionic contrast agent (ioversol). Approximately 5 hours after angioplasty, bilateral local swellings were noted near the mandible; the masses were moderately firm and nontender.Iodide mumps was diagnosed in the patient. Intravenous dexamethasone (10 mg) was administered. The submandibular glands had shrunk by 11 hours after angioplasty, and they gradually became softer. The mandibular salivary glands had completely recovered by 5 days after surgery.Iodide mumps represents a rare late reaction to iodine-containing contrast media. This condition can occur in any patient receiving any iodinated contrast agent and may recur upon repeated exposure, but self-resolution can be expected within 2 weeks. All clinicians who use contrast media or iodide should be aware of this condition.

Abstract
CONTEXT Thyroid hormone production is dependent on adequate iodine intake. Excess iodine is generally well-tolerated, but thyroid dysfunction can occur in susceptible individuals after excess iodine exposure. Radiological iodinated contrast media represent an increasingly common source of excess iodine. OBJECTIVE This review will discuss the thyroidal response after acute exposure to excess iodine; contrast iodine-induced thyroid dysfunction; risks of iodine-induced thyroid dysfunction in vulnerable populations, such as the fetus, neonate, and patients with impaired renal function; and recommendations for the assessment and treatment of contrast iodine-induced thyroid dysfunction. METHODS Data for this review were identified by searching PubMed, Google Scholar, and references from relevant articles from 1948 to 2014. CONCLUSIONS With the increase in the use of computed tomography scans in the United States, there is increasing risk of contrast-induced thyroid dysfunction. Patients at risk of developing iodine-induced thyroid dysfunction should be closely monitored after receiving iodinated contrast media and should be treated as needed.

Abstract
Radiocontrast media (RCM) are medical drugs used to improve the visibility of internal organs and structures in X-ray based imaging techniques. They may have side effects ranging from itching to a life-threatening emergency, known as contrast-induced nephropathy (CIN). We define CIN as acute renal failure occurring within 24-72 hrs of exposure to RCM that cannot be attributed to other causes. It usually occurs in patients with preexisting renal impairment and diabetes. The mechanisms underlying CIN include reduction in medullary blood flow leading to hypoxia and direct tubule cell damage and the formation of reactive oxygen species. Identification of patients at high risk for CIN is important. We have reviewed the risk factors and procedures for prevention, providing a long list of references enabling readers a deep evaluation of them both. The first rule to follow in patients at risk of CIN undergoing radiographic procedure is monitoring renal function by measuring serum creatinine and calculating the eGFR before and once daily for 5 days after the procedure. It is advised to discontinue potentially nephrotoxic medications, to choose radiocontrast media at lowest dosage, and to encourage oral or intravenous hydration. In high-risk patients N-acetylcysteine may also be given.
