Assessment of seasonal variations in surface water quality of the Balikligol Lakes, Sanliurfa, Turkey

The Balikligol freshwater lakes (Lake Ayn-i Zeliha and Lake Halil-ur Rahman) in Sanliurfa are located in the Southeastern Anatolian region, Turkey. They have not only environmental value, but are also of touristic value due to their historical and sacred status in the past and present, as well as their natural aquarium look. From time to time, fish deaths have been observed, possibly by deteriorating water quality. Therefore, water samples collected from 7 different points in the Balikligol lakes during a one-year period were analyzed monthly for 11 physico-chemical water quality parameters (temperature, pH, conductivity, chemical oxygen demand (COD), dissolved oxygen (DO), Fe, Na, Cr, Cu, Ni, and Pb). In general, the measured parameters comply surprisingly well with the standard values. DO values are within the range given in International and Turkish standards. As far as COD values are concerned, they met the standard, except for the summer period. To meet with standard COD values, aeration must be done during the summer period, and the feeding of fishes should be kept under control. The average pH values were between 7-7.7. The analyses also showed that Cu, Ni and Ph were not present, and Fe, Cr and Na levels complied with the standards

Protective effect of N-acetylcysteine from drug-induced ototoxicity in uraemic patients with CAPD peritonitis

Aim. Peritonitis is currently one of the leading complications of continuous ambulatory peritoneal dialysis (CAPD) treatment. Aminoglycosides and vancomycin are used in the treatment of CAPD peritonitis despite their potential risk for ototoxicity. N-acetylcysteine (NAC) is a molecule used in the treatment and prophylaxis of many diseases related to oxidative stress. The aim of this study was to examine whether ototoxicity due to antibiotics used in the treatment of CAPD peritonitis can be prevented by NAC

Correlation between Hearing Loss and Peritonitis Frequency and Administration of Ototoxic Intraperitoneal Antibiotics in Patients with CAPD

Aim. Aminoglycosides have been used in the treatment of CAPD peritonitis despite their potential risk for ototoxicity. The ototoxicity risk of intraperitoneally administered aminoglycosides has been investigated by a number of studies. However, their results are somewhat conflicting. The aim of the present study was to examine the frequency of hearing loss and the correlation between the repeated doses of aminoglycosides and hearing loss in CAPD peritonitis therapy. Methods. Hearing functions of the CAPD patients who had developed peritonitis and had been treated with various antibiotics including aminoglycosides were compared with those CAPD patients who had never developed peritonitis. Threshold values for hearing were determined through "pure tone audiometry" measurements. Results. Hearing threshold levels of the patients with history of peritonitis were found to be significantly higher in both lower [pure tone averages - 1 (PTA-1)] and higher [pure tone averages - 2 (PTA-2)] frequencies, when compared to the ones with no history of peritonitis (p values were 0.001 and 0.007, respectively). Conclusion. The present study showed that intraperitoneal aminoglycoside administration in CAPD patients is associated with the development of hearing loss. The severity of hearing loss may range from mild hearing loss to profound deafness. A remarkable correlation exists between the severity of the hearing loss and the repeated and total aminoglycoside dose received.</

A preliminary study of shear wave elastography for the evaluation of unilateral palpable undescended testes

Objectives: We sought to compare unilateral palpable undescended testes and contralateral descended testes using shear wave elastography (SWE) to show potential quantitative differences in elasticity patterns, which might reflect the histologic features
