1/14. Documented hyperparathyroidism of thirty-six years' duration.The fascinating history of the first Memorial Hospital patient who was diagnosed as having hyperparathyroidism is reviewed. The illness presented as a cystic mass in a femur in 1929, which was treated with radiation. When the patient was first seen at Memorial Hospital in 1931, the diagnosis of osteitis fibrosa cystica was made; serum calcium was 14 mg/100 ml. In 1932, 6 years after Mandl performed the first parathyroidectomy ever for osteitis fibrosa cystica, this patient's neck was explored, and a right hemithyroidectomy was done, with removal of two normal parathyroid glands. The parathyroid tumor was finally located and partially removed in 1937 after a second failure at neck exploration in 1936. Correspondence between Dr. Edward D. Churchill at the massachusetts General Hospital and Dr. Bradley Coley at Memorial Hospital indicated the concern at that time about uncontrollable tetany, which had been fatal in some contemporary cases and which had led to the practice of only partially removing the tumor. Following this, the patient was observed with documented hypercalcemia and chemical evidence of hyperparathyrodism until age 79. The physical and chemical abnormalities over the years up to and including her last exam are presented. The case is important not only from the historical viewpoint, but because it lends a perspective to long-term parathyroid disease, which is becoming less appreciated in this day of the routine serum calcium by SMA-12 screening. The question of partial parathyroidectomy for adenoma or hyperplasia is reviewed, and the question of observation of patients with mild hypercalcemia who probably have parathyroid tumors is discussed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/14. An unusual cause of hypercalcemia in polycythemia vera: parathyroid adenoma.In this paper we describe a patient with polycythemia vera (PV), who presented with hypercalcemia due to a parathyroid adenoma. In November 1999, the patient was admitted to our hospital with meteorism and constipation. Her physical examination revealed plethora and hepatosplenomegaly. Laboratory data revealed hyperparathyroidism in addition to PV: Rbc 8 x 10(6)/mm3, Hct 63.7%, serum calcium 13.4 mg/dl, serum phosphorus 1.2 mg/dl, albumin 4.25 mg/dl, and alkaline phophatase activity 433 U/l. Intact parathyroid hormone level (iPTH) was 376 pg/ml (n.v.12-72 pg/ml). Twenty-four hour urinary calcium excretion was higher than normal (900 mg). A parathyroid adenoma was detected with Tc-99m sesta-MIBI scanning under the left lobe of the thyroid gland and an ultrasonographic examination of the neck also supported the diagnosis. The patient was recommended for surgery. The histopathological examination confirmed the diagnosis. Postoperatively, iPTH dropped to 53.4 pg/ml at the 15 th minute and to 33.5 pg/ml at the first hour. The calcium level was 7.5 mg/dl one hour after the operation. Five days later, Hct was 40.8%. This case represents a rare association between PV and primary hyperparathyroidism, and may provide evidence for a causal link between PTH and polycythemia vera in our patient. In conclusion, this case indicates that the differential diagnosis of hypercalcemia and polycythemia vera should also include the possibility of a parathyroid tumor in addition to malignancy.- - - - - - - - - - ranking = 12.677323560359keywords = physical examination, physical (Clic here for more details about this article) |
3/14. Unusual presentation of a giant parathyroid adenoma: report of a case.Parathyroid adenomas account for most cases of primary hyperparathyroidism (1 degrees HPT). Certain symptoms and biochemical abnormalities alert the surgeon to their presence, since these benign tumors are rarely evident on physical examination. Moreover, because they are usually very small, preoperative localization using sestamibi scanning or ultrasonography is required to avoid bilateral neck exploration. Parathyroid adenomas rarely attain huge proportions. We report a case of a parathyroid adenoma measuring 8 x 5 x 3.5 cm and weighing 110 g; to our knowledge the greatest mass reported in the literature. Interestingly, despite its huge size it did not cause many of the hypercalcemic symptoms usually associated with larger adenomas, but rather it manifested with symptoms of local pressure, another unusual property of this atypical tumor.- - - - - - - - - - ranking = 12.677323560359keywords = physical examination, physical (Clic here for more details about this article) |
4/14. Primary hyperparathyroidism presenting with musculoskeletal manifestations in a young patient: a case report.A 21 year old female patient was admitted to Tikur Anbessa Hospital with a diagnosis of primary hyperparathyroidism secondary to parathyroid adenoma. Her predominant presentation was with an anterior neck mass, diffuse osteoporosis and myopathy. The diagnosis was suggested by her clinical symptoms, physical findings, Laboratory studies and radiological survey. The tissue biopsy was also compatible with of the diagnosis. The parathyroid gland was removed surgically and the patient improved significantly. Primary hyperparathyroidism is extremely rare in young patients and presentation with myopathy is even more rare. Routine determination of serum calcium and phosphorus is recommended in patients with such presentations.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/14. Acute relapsing pancreatitis in primary hyperparathyroidism with hypercalcemia aggravated after aspiration cytology: report of a case.In 1957, Cope and his associates first noted 2 cases of pancreatitis associated with primary hyperparathyroidism. They emphasized the association of hyperparathyroidism and pancreatitis. Since then pancreatitis has become a diagnostic clue to primary hyperparathyroidism. We report herein a 39-year-old woman who had suffered from acute relapsing pancreatitis 3 times in the past 2 years. hypercalcemia persisted throughout the course. A movable mass 3 x 3 cm in diameter was noted over the right thyroid area on physical examination. A hypoechogenic mass 3.5 x 2.7 x 1.4 cm was found between the right lobe of the thyroid and the carotid artery. Because of a persistently high serum level of Ca2 , normal saline and furosemide were infused; the serum Ca2 decreased gradually. After aspiration of the suspected mass, the serum level of Ca2 increased from 8.7 mg/dL to 18 mg/dL. Because of the impression of parathyroid adenoma, surgery was performed and a 3 x 2.5 x 1.5 cm well-encapsulated mass was excised without difficulty. Pathologic examination revealed a well-encapsulated parathyroid adenoma. This case reveals that primary hyperparathyroidism maybe one of the causes of pancreatitis, and aspiration cytology, although it may be helpful for the diagnosis, can aggravate the hypercalcemia.- - - - - - - - - - ranking = 12.677323560359keywords = physical examination, physical (Clic here for more details about this article) |
6/14. Primary hyperparathyroidism mimicking vaso-occlusive crises in sickle cell disease.We report a case of bone pain associated with primary hyperparathyroidism in a patient with sickle cell disease. A 17-year-old girl with sickle cell disease (SS phenotype) was seen for bilateral knee and back pain. She had had recurrent severe vaso-occlusive crises and acute chest syndrome in the course of her disease. In the last 2 years, she had frequent visits to the emergency department for severe bone pain. She complained of long-standing fatigue and lethargy. Her physical examination was normal. hydroxyurea treatment, as well as and long- and short-acting narcotics were given, with little improvement in symptoms. Poor compliance with medication, family dysfunction, and potential narcotic addiction were felt to be significant contributors to the patient's symptoms. She was incidentally found to have an extremely elevated total calcium level of 3.19 mmol/L (range: 2.25-2.76) with an ionized calcium level of 1.9 mmol/L (range: 1.15-1.35). phosphorus level was 0.82 mmol/L (range: 0.90-1.50), alkaline phosphatase level was elevated at 519 U/L (range: 10-170), and parathyroid hormone level was extremely high at 1645 pg/mL (range: 10-60). Her renal function was normal. ultrasonography of the neck and a Sestamibi scan revealed a single left inferior parathyroid adenoma adjacent to the thyroid lobe. There was no evidence of an underlying multiple endocrine neoplasia. The patient was diagnosed with primary hyperparathyroidism. Fluid hydration, hydrocortisone, calcitonin, and bisphosphonates were initiated for acute hypercalcemia management before surgical excision of the left parathyroid adenoma. On review of previous blood work, a borderline calcium level of 2.72 was present 18 months before this admission. Two years postsurgery, she has normal renal function, calcium, and parathyroid hormone levels. The weekly visits to the emergency department for pain episodes decreased to 1 every 2 months within the first few months after her surgery. The decrease in pain episodes, even if it coincided with the treatment of primary hyperparathyroidism, may still reflect the natural evolution of sickle cell disease in this patient. However, the high morbidity associated with primary hyperparathyroidism was successfully prevented in this patient. Primary hyperparathyroidism is rare in childhood. In a recent study, it occurred more commonly in female adolescents and was because of a single adenoma, as in our patient. Significant morbidity, mainly secondary to renal dysfunction, was because of the delay in diagnosis after the onset of symptoms (2.0-4.2 years), emphasizing the need for a rapid diagnosis. Sickle cell disease affects approximately 1 of every 600 blacks in north america. Acute episodes of severe vaso-occlusive crisis account for > 90% of sickle cell-related hospitalizations and are a significant cause of morbidity in patients. There is no known association between sickle cell disease and primary hyperparathyroidism, and this case is most probably a random occurrence. However, as emphasized by this case report, pain may also be a harbinger of other disease processes in sickle cell disease. Because management may vary, we suggest that care providers consider the diagnosis of vaso-occlusive crisis as the diagnosis of exclusion and that other etiologies for pain be envisaged in this patient population, especially in the presence of prolonged pain or unusual clinical, radiologic, or biological findings.- - - - - - - - - - ranking = 12.677323560359keywords = physical examination, physical (Clic here for more details about this article) |
7/14. Metastatic calcifications and severe hypercalcemia in a patient with parathyroid carcinoma.Primary hyperparathyroidism is rarely produced by parathyroid carcinoma. We present the case of a 63-yr-old man who was admitted due to recent onset of constipation, weakness and progressive lethargy. At physical examination, a left cervical mass was palpated. Marked hypercalcemia (serum calcium 25 mg/dl) (6.22 mmol/l) complicated by renal insuficiency (serum creatinine 4.4 mg/dl) (388 micromol/l) was found, but both were unresponsive to conventional therapy and hemofiltration. autopsy examination showed a carcinoma of the upper left parathyroid gland, multiple foci of metastatic calficications in the vessel walls and parenchyma of both lungs and kidneys, and the myocardium, which contributed to multi-organ failure and death. In addition to describing the clinical presentation, we review the mechanism of metastatic calcifications as well as the role of renal function and hyperphosphatemia, and the basis for therapy of hypercalcemic crisis.- - - - - - - - - - ranking = 12.677323560359keywords = physical examination, physical (Clic here for more details about this article) |
8/14. Parathyroid carcinoma: clinical presentation and treatment.Parathyroid tumors account for only a small percentage of all head and neck neoplasms. The overwhelming majority of these are parathyroid adenomas that result in primary hyperparathyroidism. From 0.5% to 4% of hyperparathyroid patients, however, will be found to have a parathyroid carcinoma. In this paper, the authors relate their recent experience with such a patient and with two other such cases. Parathyroid carcinoma patients usually present with striking hyperparathyroidism and hypercalcemia, with the resultant related symptoms being more severe than those associated with parathyroid adenomas. Parathyroid carcinomas also tend to be large and may be detectable by current imaging techniques. The surgical appearance of these lesions is also distinct; the tumors are frequently multilobulated, gray-tan in color, quite firm, and often invasive. These physical findings are important since frozen section diagnosis may be difficult. The final histologic diagnosis depends on the presence of mitotic figures and capsular and vascular invasions. Preoperative medical problems, surgical approach, and prognostic factors are also discussed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
9/14. Neuropsychiatric disorders in primary hyperparathyroidism.This is a report of two middle-aged women whose diagnosis of PHPT was made on hypercalcemia during treatment of depression and paranoid state, leading to the surgical confirmation of parathyroid adenoma. After the operation, their mental symptoms disappeared as the blood level of calcium was depressed in both cases, and there has been no recurrence for 12 and 18 months, respectively. In Case, 1 antipsychotics were effective, though transiently, for the mental symptoms other than physical ones. In Case 2, levodopa and hypercalcemia might have acted synergistically. Abnormal metabolism of magnesium was not noted in either case. A preoperative EEG showed the presence of sporadic slow waves in Case 1 and low voltage activity in Case 2. After the operation, the EEG showed an improvement to regular hypersynchronous alpha activity in both cases. The mechanism involved in the appearance of mental symptoms and EEG findings in hypercalcemia were discussed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
10/14. carcinoma of the parathyroid gland: is it overdiagnosed? A report of three cases.The true incidence of carcinoma of the parathyroid gland is probably about 1 percent of cases of primary hyperparathyroidism. Overreporting may occur if the diagnosis is based on histologic appearances alone because the histologic criteria are less than definitive. carcinoma of the parathyroid gland, if diagnosed early and treated with adequate surgical excision, is associated with a satisfactory long-term prognosis. However, the possibility of distant metastases or locally recurrent disease is not necessarily excluded by a prolonged interval of disease-free status, and the physician should continue to follow the patient on a regular basis by physical examination and routine serum calcium analysis.- - - - - - - - - - ranking = 12.677323560359keywords = physical examination, physical (Clic here for more details about this article) |
