..Our results are probably related mainly to earlier sunscreens of low SPF. They substantiate the hypothesis that sunscreen use, by permitting more time sunbathing, is associated with melanoma occurrence...

..A decrease in the intraoperative parathyroid hormone (PTH) level predicts long-term operative success...

..A variety of clinical and biochemical variables may be associated with hypocalcemia after surgery for parathyroid adenoma...

..Metabolic abnormalities in pHPT may include urate. We therefore evaluated the metabolic arteriosclerotic risk profile in pHPT with special focus on the role of urate...

..However, the technique alone does not reliably predict multiglandular disease. Potentially the failure rate in scan-directed parathyroidectomy could increase, with up to 10% of patients without ioPTH...

..Thus patients operated on for parathyroid adenoma with postoperatively elevated serum PTH levels showed decreased peripheral sensitivity to PTH...

..Because many pHPT patients have low oral calcium intake and a vitamin D deficiency, it would be of interest to evaluate the role of postoperative calcium/vitamin D supplements...

..Furthermore, the influence of surgery on biochemical variables associated with pHPT was analyzed...

..An increased risk for recurrent disease is postulated for some of the patients who do not normalize their PTH levels postoperatively, and long-term surveillance of these patients is suggested...

..Furthermore, the serum calcium concentration does not reflect disease severity in pHPT...

..A sufficient decline in levels of parathyroid hormone measured intraoperatively (ioPTH) precludes early and late surgical failures...

..To compare unilateral and bilateral neck exploration for primary hyperparathyroidism in a prospective randomized controlled trial...

..Thus, we adopted a policy of postoperative supplements with calcium and vitamin D after parathyroid surgery. In this study, we investigated if this policy enhanced the postoperative increase in bone density...

..We report the surgical treatment of a consecutive series of scan negative patients with the intention of unilateral parathyroid exploration with the aid of intraoperative quick PTH (qPTH)...

..In a recent study, we could not find an increased incidence of involuntary childlessness. The aim of this study was to evaluate this issue further...

..In conclusion, serum levels of 25-hydroxyvitamin D3 and PTH were independently associated with a history of bone fractures in pHPT. These variables should be considered when evaluating patients for parathyroid surgery...

..The aim of this study was to compare patient outcome in both groups at a median follow-up of 7.3 years after operation...

..Low intraoperative PTH levels during thyroid surgery are therefore a feasible predictor of postoperative hypocalcemia...

..All patients had free T4 and T3 levels within normal range preoperatively...

..The coexistence of hyperthyroidism and primary hyperparathyroidism (pHPT) has been reported. We have questioned whether hypercalcemia or surgical trauma contribute to transient hyperthyroidism following parathyroid surgery...

..04 for both). To our knowledge this is the first description of the histopathological features of CMMs from families with mutations in the CDKN2A gene...

....

..These changes were not due to parathyroid insufficiency. Instead, our results imply increased parathyroid sensitivity to calcium and possibly reduced peripheral sensitivity to PTH...

..Instead, the results imply there is diminished calcium absorption and increased bone turnover with cortical bone remineralization...

..The aim of this study was to determine the prevalence of male infertility after bilateral mesh repair...

..The results based on histopathological re-examinations and those based on tumour registry data were essentially the same...

..8 mm) in 1985 (P = 0.01) and 1989 (P = 0.002) compared with 1965. The incidence of melanomas with inflammation increased significantly (P = 0.04), as did age at diagnosis (P = 0.005)...

..To compare long-term patient outcome in a prospective randomized controlled trial between unilateral and bilateral neck exploration for primary hyperparathyroidism (pHPT)...

..No difference was seen in overall complications. However, 2 recurrences did occur after 1 year in the TEP group...

..An increased risk was related to commercial exposure and to exposure during the winter. The results substantiate the hypothesis that exposure to sunbeds might increase the risk of developing malignant melanoma...

..To our knowledge, no previous study has evaluated the HS dissection technique in a homogenous group of patients with Graves' disease undergoing total thyroidectomy...

..g. nonmelanoma skin cancer (NMSC), were studied descriptively. So far the mutation 113insArg explains all CDKN2A-associated CMM in ethnic Swedes...

..Analysis of microsatellite markers adjacent to the p16 gene at chromosomal region 9p21 revealed that both families share a common haplotype, in keeping with a common ancestor...
