The introduction of assays for the intact parathyrin (parathyroid hormone) has dramatically improved the diagnosis and follow-up of patients with primary hyperparathyroidism. However, in some patients with mild or intermittent hypercalcaemia, when plasma concentrations of intact parathyrin may be within the normal reference concentrations, the diagnosis of primary hyperparathyroidism may still be

It is not known whether thyroid surgery evokes changes in calcium metabolism. We therefore studied 6 patients operated upon with hemithyroidectomy for benign thyroid diseases, preoperatively and at 3 months and 1 year postoperatively. We measured changes in serum levels of intact parathyroid hormone (PTH), vitamin D metabolites, ionized calcium, phosphate, osteocalcin, thyroid hormones and bone de

Primary hyperparathyroidism (pHPT) is associated with a right-shifted relation between parathyroid hormone (PTH) secretion and calcium. However, it is also possible that a decreased suppressibility of PTH secretion by calcium is important for maintaining hypercalcemia in pHPT. We therefore compared the suppression of serum levels of intact PTH induced by a 1.5-gram oral calcium load in patients wi

Primary hyperparathyroidism (pHPT) is associated with osteopenia. However, the individual variation in recovery in bone mass after surgery is large. Therefore, modes of prediction of the increase in bone mass after parathyroid surgery were investigated. Preoperatively and at one year after surgery bone mineral content (BMC) in the distal radius was measured with single photon absorptiometry techni

AL-Karama dam, the second largest dam in Jordan, was constructed in the Jordan valley area in the year 1979. Currently, the dam holds about 72% of its designed storage capacity with total dissolved solids concentration of 2.2%. The dam water was designed to irrigate 100 km2 of new reclaimed areas and to provide drinking water for more than 30,000 residences. In this work, solar desalination system

Unilateral neck exploration for primary hyperparathyroidism (pHPT) of old and high risk patients can be safely performed under local anesthesia, provided there is a correct preoperative side localization of the enlarged parathyroid gland. We performed large vein sampling and measured intact parathyroid hormones (PTH) with a new, highly sensitive immunoradiometric assay. The method was used before

Patients with primary hyperparathyroidism are often elderly with cardiovascular disease and in some an operation might be hazardous owing to anaesthetic complications. A technique for operation for primary hyperparathyroidism under local anaesthesia is described. The method uses a unilateral approach. Seventeen consecutive patients operated on under local anaesthesia were compared with a group of

OBJECTIVE: To clarify the association between primary hyperparathyroidism and cortical osteopenia.DESIGN: Open study.SETTING: Department of Surgery, University of Lund, Sweden.SUBJECTS: 38 patients with primary hyperparathyroidism.OUTCOME MEASURES: Correlation between bone density (measured by single photon absorption) and age; sex; serum concentrations of parathyroid hormone and ionised calcium;

To improve the sensitivity of thallium-technetium subtraction scintigraphy for preoperative localization procedure of enlarged parathyroid glands in primary hyperparathyroidism, we administered calcitonin intramuscularly 4 hours before the scintigraphy in 14 consecutive patients. Injection of calcitonin reduced plasma levels of ionized calcium from 1.47 +/- 0.10 mmol/l to 1.41 +/- 0.09 mmol/l (p l

Background Psychological stress is an independent risk factor for cardiovascular disease (CVD), but the mechanism by which stress is associated with CVD is not entirely understood. Although genetic factors are implied in both stress responsivity and cardiovascular reactivity, no studies to date have investigated their interactions with stress for cardiovascular end points. The objective was to elu

Background Psychological stress is a modifiable risk factor for health outcomes and can be managed through coping mechanisms. Biological and behavioral hypotheses have been proposed to explain the association between stress coping strategies and cancer outcomes. Methods The Japan Public Health Center-based study asked questions on coping behaviors in its 10-year follow-up survey. 55,130 subjects a

The association between alcohol intake and colorectal cancer (CRC) may vary secondary to single nucleotide polymorphisms (SNPs) in two pathways related to alcohol intake. 375 cases of CRC were identified among 38 373 Japan Public Health Center-based prospective Study (JPHC Study) participants who had returned a baseline questionnaire, reported no diagnosis of any cancer and provided blood samples.

Aims: Coping strategies may be significantly associated with health outcomes. This is the first study to investigate the association between baseline coping strategies and cardiovascular disease (CVD) incidence and mortality in a general population cohort. Methods and results: The Japan Public Health Center-based prospective Study asked questions on coping in its third follow-up survey (2000- 04).

Background: Non-participants to psychosocial studies have been shown to have higher mortality, and mortality differs between partial and complete responders to psychosocial questionnaires. Yet, there is very little information available directly linking survey response status with completing suicide. Methods: The study population consisted of the participants of the Japanese Public Health Center-b

Purpose: Cross-sectional studies have shown an association between different coping styles and suicidal behavior. It is unknown whether there is any prospective association between coping behaviors and suicide in the general population. Methods: The study population consisted of participants of the Japanese Public Health Center-based Prospective Study. In the 10-year follow-up questionnaire, subje

We present a few-cycle high-repetition rate optical parametric amplifier for multiphoton PEEM experiments on semiconductor nanowires. This parametric amplifier is also used for the generation of high-order harmonics at 200kHz for future atto-PEEM experiments.

Located in the southeastern parts of the Baoulé Mossi domain of the West African Craton, the Birimian terrane in Ghana is known to consist of predominantly juvenile crust emplaced during the Eburnean orogeny. Here we present novel coupled zircon U-Pb and Lu-Hf isotope data from nine Birimian granitoids intruding different domains from northwestern, western and southeastern Ghana. Sub-chondritic e(
