Even asymptomatic patients should be considered for surgery MJA The report by Delbridge et al in this issue of the Journal describes the changing clinical picture of primary hyperparathyroidism (PHPT) in patients referred for surgical treatment at Royal North Shore Hospital, Sydney, over the past 30 years. The most common presentation in the 1990s is in women over the age of 50 years with bone loss indistinguishable from that of postmenopausal or senile osteoporosis (31%). Patients with kidney stones still constitute 15%, and those with subtle but distressing symptoms of fatigue, depression or altered cognitive function constitute 20%. Delbridge et al have also observed an "exponential" increase in the number of cases referred for surgery over the past decade, reflecting contemporary epidemiological studies which have unearthed a virtual epidemic of PHPT among postmenopausal women it affects 2% to 3% of women in this age group. Even so, the absolute number of patients undergoing operation at Royal North Shore Hospital each year remains small when compared with the number expected by extrapolation from this prevalence. Presumably, this is due in part to underdiagnosis of PHPT, as well as continuing reluctance among physicians to refer patients for surgery unless they have marked hypercalcaemia or overt "bone or stone" disease.

Current contents list MJA Abstract Objective: To examine changes over the past three decades in the indications for, and outcomes of, surgery for primary hyperparathyroidism. Design: Survey of a prospective hospital database. Setting: Royal North Shore Hospital (a tertiary referral and university teaching hospital), Sydney, New South Wales, January 1962 to December 1996. Patients: All 733 patients who underwent neck exploration for primary hyperparathyroidism. Results: The annual number of parathyroidectomies increased virtually exponentially, from a mean of two in 1962-1969 to 73 in 1996. In the 1960s and 1970s, the most common indication for surgery was the presence of renal calculi (58% and 43%, respectively), but in the 1980s there was a marked increase in presentation of asymptomatic disease after biochemical screening (19%). In the 1990s, low bone mineral density detected by osteodensitometry has become the most common indication for surgery (31%). After initial operation, 11 patients (2%) had persistent hypercalcaemia, with five of these cured by reoperation an overall failure rate of 1%. Conclusions: Surgery for primary hyperparathyroidism has become increasingly common, with low bone mineral density replacing renal calculi as the most common indication for surgery. Neck exploration in experienced hands results in an overall cure rate of 99%.

Disease Injury Nutrition Poison ... Prevention Hyperparathyroidism Definition: excessive production of parathyroid hormone by the parathyroid glands. Causes, incidence, and risk factors: Hyperparathyroidism can be caused by enlargement of one or more of the parathyroid glands or in response to abnormally low calcium levels in the blood. The parathyroid glands are located at the front and base of the neck around the thyroid gland and produce parathyroid hormone . Parathyroid hormone regulates calcium, phosphorus, and magnesium balance within the blood and bone by maintaining a balance between the mineral levels in the blood and the bone. Excessive levels of parathyroid hormone disturbs this balance and results in increasing the blood calcium level by reabsorbing it from the bone and increasing absorption from the kidneys and intestines. The effects of abnormal calcium levels are seen in several body systems including the skeletal, gastrointestinal, renal , muscular, and central nervous system Related topics: Parathyroid related hypercalcemia Primary hyperparathyroidism Secondary hyperparathyroidism Tertiary hyperparathyroidism Review Date: 6/1/01 Reviewed By: Carlos Bernal-Mizrachi, M.D., Department of Endocrine and Metabolism, Washington University, St. Louis, MO.

Hyperparathyroidism What is hyperparathyroidism? Hyperparathyroidism is caused by overactive parathyroid glands. Overactive parathyroid glands produce high levels of parathyroid hormones, which, in turn, results in increased levels of calcium in the blood stream. The excess calcium released by the bones leads to osteoporosis and osteomalacia (both bone-weakening diseases). Another result of hyperparathyroidism is kidney stones, because of high levels of calcium excreted into the urine by the kidneys. Hyperparathyroidism is quite rare in children.

It is hoped that this article may be helpful.. Editor Primary hyperparathyrodism is a disorder of the parathyroid glands. Most people with this disorder have one or more enlarged, overactive parathyroid glands that secrete too much parathyroid hormone. In secondary hyperparathyroidism, a problem such as kidney failure makes the body resistant to the action of parathyroid hormone. This article focuses on primary hyperparathyrodism. What are the parathyroid glands? The parathyroid glands are four pea-sized glands located on the thyroid gland in the neck. Occasionally, a person is born with one or more of the parathyroid glands embedded in the thyroid, the thymus, or elsewhere in the chest. In most such cases, however, the glands function normally. Though their names are similar, the thyroid and parathyroid glands are entirely separate glands, each producing distinct hormones with specific functions. The parathyroid glands secrete parathyroid hormone (PTH), a substance that helps maintain the correct balance of calcium and phosphorus in the body.

Primary hyperparathyroidism is rare in children under the age of sixteen and uncommon in adolescents.1 While most cases of primary hyperparathyroidism in neonates and infants are caused by parathyroid hyperplasia, the majority of cases appearing during childhood and adolescence are caused by a parathyroid adenoma.2 A female Sudanese infant who has primary hyperparathyroidism due to parathyroid hyperplasia is presented. Results of workup, possible etiologies and review of the literature on primary hyperparathyroidism are presented. To our knowledge, this is the first case reported at this age in the Arab world. Case Report Laboratory investigations showed calcium level of 6 mmol/L (N = 2.1 to 2.6), phosphate 2.2 mmol/L (N = 0.8 to 1.4), magnesium 1.8 mmol/L, alkaline phosphatase 670, albumin 47 g/L, urine Ca/urine creatinine ratio 9.6 (N = 0.7), vitamin D level 43 (N = 20 to 120), serum parathyroid hormone (PTH) 285 (N = 5 to 45) with calcium level of 4.22, urine homovanillic acid (HVA) 0.3 mg/24 hours (N = up to 4.1). Vitamin D, PHT and HVA were done by Bioscientia Laboratories in Germany. The patient's father, mother and uncle had normal calcium levels. Electrocardiogram showed sinus tachycardia. Echocardiogram showed normal aortic arch. Abdominal and neck ultrasound, x-ray of both hands, and brain and neck computed tomography (CT) scans were also normal. Parathyroid scan (thallium scan) showed a hot area in the right lower parathyroid gland with suspicion of parathyroid adenoma.

echt home block II pathology parathyroid menu Primary Hyperparathyroidism Primary hyperparathyroidism results from disorders intrinsic to the parathyroid glands, and occurs in approximately 1 in 800 adults. The hypersecretion of parathyroid hormone results in hypercalcemia (34% of the clinical causes of hypercalcemia), hypophosphatemia, and excessive urinary excretion of calcium. The earliest clinical signs are neuromuscular weakness and fatigue and neuropsychiatric disturbances ranging from depression, anxiety and psychoses. Renal stones or nephrocalcinosis due to hypercalciuria are seen in 50 - 70% of patients, and is the most common clinical presentation. Reabsorption and remodeling of bone may result in osteitis fibrosa cystica, which is diagnostic of hyperparathyroidism. Soft tissue calcifications may occur in about 15 - 20 % of the cases, due to hypercalcemia. Remember: not all hypercalcemia is due to hyperparathyroidism. Nonparathyroid malignancy is the most common cause (35%) of hypercalcemia in hospitalized patients. Other causes include vitamin D excess (12%), hyperthyroidism (4%), milk alkali syndrome (4%), and immobilization (2.3%). Laboratory error may account for as much as 13.4% of elevated serum calcium levels. Other conditions with

Hyperparathyroidism is caused by overactive parathyroid glands. Overactive parathyroid glands produce high levels of parathyroid hormones, which, in turn, results in increased levels of calcium in the blood stream. The excess calcium released by the bones leads to osteoporosis and osteomalacia (both bone-weakening diseases). Another result of hyperparathyroidism is kidney stones, because of high levels of calcium excreted into the urine by the kidneys. Hyperparathyroidism is quite rare in children. What causes hyperparathyroidism? Causes of hyperparathyroidism include benign (non-cancerous) tumors on the parathyroid glands or enlargement of the parathyroid glands. What are symptoms of hyperparathyroidism? According to a recent study, children with hyperparathyroidism experience more severe symptoms than adults. The following are the most common symptoms of hyperparathyroidism in children. However, each child may experience symptoms differently. Symptoms may include: kidney pain (due to the presence of kidney stones) diminished bone density that causes bone pain aches and pains abdominal pain nausea vomiting fatigue excessive urination confusion muscle weakness The symptoms of hyperparathyroidism may resemble other conditions or medical problems. Always consult your child's physician for a diagnosis.

Hyperparathyroidism by Erin O'Donnell DVM The parathyroid gland helps regulate calcium levels in the blood. When calcium levels are low, the parathyroid gland released parathyroid hormone (PTH), which causes the release of calcium from the bones into the blood. The parathyroid gland is found very close to the thyroid gland, in the neck region. Primary hyperparathyroidism is a condition in which the parathyroid gland secretes too much PTH, and causes there to be too much calcium in the blood. Primary hyperparathyroidism is caused by a tumor or overgrowth of the parathyroid gland. Typically the animals who get primary hyperparathyroidism are middle aged to older dogs and cats. Five out of the seven reported cases of the disease in cats were in female Siamese cats. The signs of hyperparathyroidism are usually related to hypercalcemia (too much calcium in the blood), but are somewhat vague. Decreased appetite, lethargy, and depression are the most common signs. Some animals will drink lots of water and have to urinate often. Less frequently, owners may notice constipation, weakness, shivering, twitching, or vomiting. Many times there are no signs, and the increased blood calcium is found when the veterinarian checks a blood chemistry panel for another problem. There are several things that must be done to diagnose primary hyperparathyroidism. Hyperparathyroidism can be secondary to kidney problems and nutritional deficiencies, and certain cancers can produce a PTH-like hormone that has the same effect as PTH. These are important things for the veterinarian to be able to eliminate as causes for elevated blood calcium. The veterinarian may also need to ultrasound the neck to look for a parathyroid tumor.
