Time course of cytokine upregulation in the lacrimal gland and presence of autoantibodies in a predisposed mouse model of Sjögren's Syndrome: the influence of sex hormones and genetic background.

Sjögren's Syndrome (SS) is a chronic, inflammatory autoimmune disease characterized by lacrimal gland lymphocytic infiltration and epithelial cell death, as well as by the presence of serum autoantibodies. Although the symptoms of this syndrome are well characterized, patients are not diagnosed until 5-10 years into disease progression; furthermore, the early series of events leading to the initiation of SS are not well understood. In order to better understand the early events of the disease, we have been using ovariectomized (OVX) NOD.

Antibiotic-associated psychosis during treatment of urinary tract infections: a systematic review.

There have been a number of case reports of antibiotic-associated psychosis in the literature that have not been systematically reviewed. Urinary tract infections (UTIs) are among the most common bacterial infections and have also been associated with acute psychosis. We performed a systematic review of cases of antibiotic-associated acute psychosis during treatment of a UTI and evaluated the strength of the association for each case.

Influence of sex hormones and genetic predisposition in Sjögren's syndrome: a new clue to the immunopathogenesis of dry eye disease.

Sjögren's syndrome (SS) is a chronic autoimmune disease characterized by lymphocytic infiltration, destruction of lacrimal and salivary glands and the presence of serum autoantibodies. Most women that suffer from SS are post-menopausal however, not all post-menopausal women develop SS, suggesting that other factors, in addition to the decrease in ovarian hormones, are necessary for the development of SS. The purposes of this study were to investigate a) the time course of lymphocytic infiltration and apoptosis in the lacrimal gland after ovariectomy, b) if a predisposed genetic background for SS aggravates the effects of decreasing levels of sex hormones in the lacrimal glands and c) if physiological doses of estrogen or androgen prevent the effects observed after ovariectomy.
