1. 1. 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

3. 2. 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.

4. 3. Interaction between Calcium, Calciotropic Hormones and the Gastrin-ECL-cell Axis

   Författare :Rebecca Gagnemo Persson; Hälsofrämjande komplexa interventioner; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; rat; chicken; parathyroid gland; stomach; vitamin D; PTH; CT; calciotropic hormones; Gastrin; calcium; ECL cell; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

   Sammanfattning : Calcium homeostasis involves mainly the interaction of PTH, vitamin D and CT. The stomach may be important for calcium homeostasis. Gastric acid is thought to mobilize calcium from the diet, thereby facilitating the absorption of calcium in the small intestines. LÄS MER

5. 4. Cardiovascular aspects in mild primary hyperparathyroidism and the outcome after parathyroidectomy

   Författare :Parastou Farahnak; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Data on the extent and clinical significance of cardiovascular abnormalities in primary hyperparathyroidism (PHPT) are conflicting. The main objective of this thesis was to evaluate the cardiovascular function in patients with mild PHPT without other known risk factors and to analyze the effect of parathyroid adenomectomy.

7. 5. Evaluation of Myocardial Function in Chronic Kidney Disease : A Colour Tissue Velocity Imaging Study

   Författare :Shirley Hayashi; Lars-Åke Brodin; Svend Aakhus; KTH; []
   Nyckelord :Cardiac; Kidney; Tissue; Velocity; MEDICINE; MEDICIN;

   Sammanfattning : In patients with chronic kidney disease (CKD), overhydration, uremic toxins and left ventricular (LV) dyssynchrony are factors that may lead to LV dysfunction and conduction abnormalities and thus contribute to the high cardiac mortality. Colour tissue velocity imaging (TVI) allows a detailed quantitative analysis of cardiac function in CKD patients, opening new possibilities to evaluate longitudinal myocardial motion, rapid isovolumetric events, LV filling pressure and LV synchronicity.
