[Systemic sclerosis - a rare but important diagnosis in primary health care].

Systemic sclerosis is an autoimmune systemic disease with an annual incidence in Sweden of only 20 cases per million and a standardised mortality rate of 3-4. Disease onset is usually preceded by a period with Raynaud's phenomenon, combined with structurally abnormal nailbed capillaries and accompanied by presence of scleroderma related autoantibodies. The presenting symptoms are skin thickness, puffy fingers, digital ulcers, dysphagia, joint stiffness and pain, and pruritus.

Parenteral nutrition and insulin per protocol improve diabetes management after total pancreatectomy.

Introduction: Pancreatogenic diabetes develops in patients undergoing total pancreatectomy and complicates post-surgical management. The aim of this study was to compare parenteral nutrition (PN) with protocolled insulin treatment to intravenous glucose treatment after total pancreatectomy.

Methods: This was a retrospective study of 97 patients undergoing total pancreatectomy between 2009 and 2014.

Influence of light environment and photoperiod on plasma melatonin and cortisol profiles in young domestic boars, comparing two commercial melatonin assays.

Eighteen crossbred boars, three siblings from each of six litters, were distributed randomly among three groups after weaning. The 'Natural long-day' group was housed in a standard room with windows, whereas the 'Artificial long-day' and 'Artificial short-day' groups were housed in light-sealed rooms and under an artificial light regimen (1400 lx). In spring (16-17 hr of light) plasma levels of melatonin and cortisol were measured in samples collected hourly for 24 hr.

Single-step divergent selection for male comb shape in two White Leghorn lines.

1. Divergent selection for comb shape (SH, the way that the cockerel bears the comb) was performed in 2 White Leghorn lines in a study aimed at assessing possibilities for improving SH. 2.

Inbreeding and inbreeding depression on reproduction and production traits of White Leghorn lines selected for egg production traits.

1. The rate of inbreeding and its effect on reproduction and egg production traits were studied in White Leghorn lines selected for egg production traits. The experiment was carried out for 10 generations in a control line (C) and in lines selected for increased egg number (EN), egg weight (EW) and egg mass (EM).

Age-dependent changes in oviposition pattern and egg production traits in the domestic hen.

Effects of aging on oviposition pattern and egg production traits were studied based on records made between age at first egg and 130 wk of age in 479 hens from three selection lines. During the 1st laying yr (age at first egg to 71 wk of age), all three lines produced equal amounts of egg mass. A significant (P < or = .

Genetic variation in the time of oviposition in the laying hen.

1. The distribution of oviposition times in modern layers is relatively narrow. Consequently, in management systems where hens have to compete for nestboxes, some eggs will be laid on the floor.
