Increased thyroid cancer risk in acromegaly

Pituitary - Acromegaly increases cancer risk. We aimed to determine the prevalence and the predictors of tumors in acromegalic patients treated at our department. We retrospectively evaluated 160...     

Simple Renal Cyst Prevalence in Internal Medicine Department and Concomitant Diseases

A total of 684 patients who had not been diagnosed with renal cyst but had undergone abdominal ultrasonography for various reasons were evaluated. Patients with and without renal cyst were classified into two groups and were compared in terms of hypertension (HT), hyperlipidemia (HL), diabetes mellitus (DM) and obesity (body mass index: ≥30 kg/m²) prevalence. Although 94 patients (13.7%) were established with a renal cyst, 590 patients (86.3%) did not have a renal cyst. The mean age of the patients established with a simple renal cyst was 67.3 ± 12.1 years (range: 28–82 years); 54 (57.4%) of them were women and 40 (42.6%) were men. Of the patients established with a simple renal cyst, 64 (68.1%) had HT, 40 (42.6%) had DM, 20 (21.3%) had HL, 42 (44.7%) were obese, 18 (19.1%) had nephrolithiasis, and 6 (6.4%) had urinary tract infection. Of the patients without a cyst, 272 (46.1%) had DM, 212 (35.9%) had HT, 122 (20.7%) had HL, and 96 (16.3%) were obese. HT and obesity were significantly higher in patients with a renal cyst when compared with those without a cyst. However, although HL incidence was higher in patients with a cyst, the difference was not significant statistically. HT, HL, and obesity are more prevalent in patients with a renal cyst when compared with patients without. Consequently, patients with a simple renal cyst should be evaluated and followed up in terms of atherosclerotic risk factors.     

Protective effect of syringic acid on kidney ischemia-reperfusion injury

The objective of the present study was to determine whether preischemic administration of syringic acid (SA) would attenuate renal ischemia-reperfusion injury (IRI). Rats were divided into three groups: Sham group; IR group; and IR?+?SA group. The effects of SA were examined using biochemical parameters including serum ischemia-modified albumin (IMA), total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), tissue superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and malondialdehyde (MDA). The apoptosis status and histopathological changes were evaluated. After calculating the score for each histopathological change, the total score was obtained by summing all the scores. In the SA group, MDA, IMA, TOS, and OSI decreased significantly compared to the IR group. After SA administration, the increase in GPx activity was found to be significant. Apoptosis decreased significantly in the SA group compared with the IR group. The total score significantly decreased after administration of SA. Taken together, our findings suggest that SA preconditioning is effective in reducing tissue damage induced in kidney IRI. Renal histology also showed convincing evidence regarding the protective nature of SA.
