TL;DR: An inherited KCNJ5 mutation that produces increased Na+ conductance in a Mendelian form of severe aldosteronism and massive bilateral adrenal hyperplasia is identified, explaining pathogenesis in a subset of patients with severe hypertension and implicate loss of K+ channel selectivity in constitutive cell proliferation and hormone production.
Journal ArticleDOI

Libutti,Shrikant Mane,Per Hellman,Gunnar Westin,Göran Åkerström,Peyman Björklund,Tobias Carling,Christoph Fahlke,Patricia Hidalgo,Richard P. Lifton +28 more
TL;DR: De novo germline mutations at identical positions in two children with a previously undescribed syndrome featuring primary aldosteronism and neuromuscular abnormalities are identified and implicate gain-of-function Ca2+ channel mutations in APAs and primary a Aldosterone-producing adenomas.
Journal ArticleDOI
Plasma Parathyroid Hormone and the Risk of Cardiovascular Mortality in the Community
Emil Hagström,Per Hellman,Tobias E. Larsson,Erik Ingelsson,Lars Berglund,Johan Sundström,Håkan Melhus,Claes Held,Lars Lind,Karl Michaëlsson,Johan Ärnlöv +10 more
TL;DR: Plasma PTH levels predict cardiovascular mortality in the community, even in individuals with PTH within the normal range, and whether PTH is a modifiable risk factor is investigated.
Journal ArticleDOI
Effect of surgery on the outcome of midgut carcinoid disease with lymph node and liver metastases.
Per Hellman,Tobias Lundström,Ulf Öhrvall,Barbro Eriksson,Britt Skogseid,Kjell Öberg,Eva Tiensuu Janson,Göran Åkerström +7 more
TL;DR: Surgery to remove the primary intestinal tumor including mesenteric lymph node metastases is supported by the present results, even in the presence of liver metastases, which are identified as major negative prognostic factors for survival.
Journal ArticleDOI
Plasma vitamin D and mortality in older men: a community-based prospective cohort study
Karl Michaëlsson,John A. Baron,Greta Snellman,Rolf Gedeborg,Liisa Byberg,Johan Sundström,Lars Berglund,Johan Ärnlöv,Johan Ärnlöv,Per Hellman,Rune Blomhoff,Alicja Wolk,Hans Garmo,Lars Holmberg,Håkan Melhus +14 more
TL;DR: Both high and low concentrations of plasma 25(OH)D are associated with elevated risks of overall and cancer mortality.
