Urate through NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome-dependent caspase-1 activation stimulates macrophages to secrete inteleukin-1β (IL-1β). Urate also enhances adaptive immunity indirectly through its effect on antigen presenting cells. In this study, the direct effect of urate on isolated primary human T-cells was evaluated. ⋯ Urate, a well defined danger signal, stimulates directly human T-cells in a NLRP3 infmmasomela-dependent way. The subsequent IL-1β secretion could enhance inflammation, whereas expansion of T-cell clones could facilitate a subsequent adaptive immune response. Hippokratia 2015, 19 (1): 41-46.

Constipation is a frequent problitalic in childhood and may be defined as delay or difficulty in defecation that persists for longer than two weeks. It is one of the ten most frequent pathological conditions that a general paediatrician deals with. The aim of this review is to provide the general paediatrician an overview of constipation in children discussing the etiology, differential diagnosis, signs and symptoms and patient evaluation. ⋯ Functional constipation ritalicains a frequent problitalic in childhood. Treatment options differ between infants and children. italicphasis on recommended regimens for maintenance and how to reduce medication will help to improve the long-term outcome. Moreover, it is of great importance to follow constipated children closely and restart medication promptly. On treatment failure or on suspicion of organic disease the patient should be referred for further evaluation. Hippokratia 2015, 19 (1): 11-19.

Anaplastic thyroid carcinoma (ATC) has the most aggressive progression among thyroid malignancies. Most of the patients have metastasis, especially to the lungs, liver and regional lymph nodes, at the time of diagnosis. Gastrointestinal tract metastasis of ATC has been rarely reported. We report a case who presented with gastrointestinal bleeding and was diagnosed with ATC accompanied with gastric, skin, lung and adrenal gland metastases. ⋯ We reported a case of ATC with gastric, skin, lung and adrenal gland metastases, initially presenting with gastrointestinal bleeding due to the gastric metastasis.

The aim of this study was to investigate the disease characteristics of children with juvenile idiopathic arthritis (JIA) in southeast Turkey. ⋯ In the present study, polyarticular JIA was the predominant subtype and there were fewer patients with positive ANA or uveitis compared to previous studies.

West Nile virus (WNV) causes to humans a variety of symptoms, from asymptomatic infection to severe neuroinvasive disease. In a previous study, it was shown that WNV IgM antibodies persisted in three of 26 (12%) patients, nine months after onset of the symptoms. The aim of the present study was to test 10 of these patients, three years post-infection for probable persistence of IgM antibodies and to investigate their IgG antibody patterns. ⋯ WNV IgM antibodies persist for more than three years in 12% of patients with WNV infection, while WNV IgG antibodies persist and even increase their levels, regardless the involvement of the nervous system, suggesting that the immune response in the symptomatic WNV infections is strong and long-lasting.
