  1. 1. Primary Hyperparathyroidism - Aspects on skeletal Involvemnt and PTH levels after Surgery

    Författare :Erik Nordenström; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; PTH infusion; PTH levels; Densitometry; Bone density; Primary hyperparathyroidism; Skeletal;

    Sammanfattning : The aim of this thesis was to evaluate risk factors for fractures in patients with primary hyperparathyroidism (pHPT), to study the association between preoperative variables and postoperative changes in bone density and to investigate long-term changes and peripheral PTH sensitivity in patients with elevated PTH levels after surgery. 203 pHPT patients were investigated with regard to clinical and biochemical variables and bone density.

  3. 2. Calcium Homeostasis After Thyroid Surgery

    Författare :Pia Lindblom; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTH-peripheral effects; hPTH- 1-34 infusion; EDTA infusion; Set-point; Vitamin D3; PTH; Calcium; Thyroid surgery; Postoperative hypocalcemia; Bone density.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Reduced thyroid hormones;

    Sammanfattning : Calcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. LÄS MER

  4. 3. Fibroblast growth factor-23 and Klotho in bone/mineral and parathyroid disorders

    Författare :Tijana Krajisnik; Tobias E. Larsson; Kenneth B. Jonsson; Östen Ljunggren; Peyman Björklund; Gunnar Sterner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; calcitriol; chronic kidney disease; CKD; chronic renal failure; fibroblast growth factor 23; fibroblast growth factor-23; FGF23; FGF-23; GalNac-T3; GALNT3; GFR; hyperostosis-hyperphosphatemia syndrome; HHS; Klotho; parathyroid hormone; PTH; hyperparathyroidism; pHPT; sHPT; uremic; vitamin D3; Endocrinology; Endokrinologi; Internal Medicine; invärtesmedicin;

    Sammanfattning : Fibroblast growth factor-23 (FGF23) is a novel, bone-produced hormone that regulates renal phosphate (Pi) reabsorption and calcitriol metabolism. Disorders of mineral and bone metabolism, such as autosomal dominant hypophosphatemic rickets (ADHR) and hyperostosis-hyperphosphatemia syndrome (HHS), witness the importance of well-balanced serum levels of FGF23.

  5. 4. Vitamin D status in psoriasis patients treated with UVB therapy

    Författare :Amra Osmancevic; Göteborgs universitet; []
    Nyckelord :Vitamin D; PTH; psoriasis; bone mineral density; ultraviolet UVB;

    Sammanfattning : Vitamin D status in psoriasis patients treated with UVB therapy Amra Osmancevic Department of Dermatology and Venereology, Institute of Clinical Sciences at Sahlgrenska Academy, University of Gothenburg, Göteborg, Sweden Abstract The thesis deals with the effect of ultraviolet B (UVB) 280-320 nm on vitamin D production in psoriasis patients during treatment with phototherapy. Background: Psoriasis is a chronic, inflammatory disease affecting the skin and potentially the joints. LÄS MER

  7. 5. Vitamin D and Breast Cancer. Studies on Incidence and Survival

    Författare :Linnea Huss; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; risk; prognosis; vitamin D; PTH; calcium; SNP; VDR.;

    Sammanfattning : Previous research has suggested beneficial effects of vitamin D on both breast cancer risk and prognosis. The overall aim of this research project was to investigate associations between vitamin D and breast cancer. The population-based prospective cohort, the Malmö Diet and Cancer Study, recruited 17,034 women in the first half of the 1990s. LÄS MER
