Potential health risk assessment, spatio-temporal hydrochemistry and groundwater quality of Yamuna river basin, Northern India.

Groundwater which is an essential source of freshwater for various domestic, agricultural, industrial applications is facing a severe deterioration in quality due to demographic pressure and intense industrial activities. Present study appraises the influence of human induced activities on groundwater quality of Agra-Firozabad industrial belts of Western Uttar Pradesh, Yamuna basin, India. The maximum concentrations of metals and anions found during pre and post monsoon are as follows: Lead 0.302; 0.086, calcium 672; 1260, magnesium 215; 16.8, cadmium 0.0; 0.066, chromium 0.016; 0.005, manganese 0.340; 0.076, nickel 0.044; 0.028, sulfate 514; 286, nitrate 66.7; 3.56 and fluoride 1.17; 2.02 mg/L respectively. Based on results of Water Quality Index, groundwater samples were classified under 'Poor water' category in 34.2% and 52.63% during pre and post-monsoon period, respectively. Accordingly, higher concentrations of bicarbonate and sulfate might have attributed to excess hardness, instrumental in making it unsuitable for industrial usage. However, values of Percent Sodium, Sodium Adsorption Ratio, Magnesium Hazard and Permeability Index signified that groundwater from majority of locations was fit for agricultural use. Health risk assessment studies revealed that children consuming polluted water were affected more as compared to adults. Timely action and strict compliance of regulation is recommended towards groundwater management for defined usage to avert severe health effects and to meet sustainable development goals.

POSTOPERATIVE COMPLICATIONS WITH GLYCINE AND STERILE DISTILLED WATER AFTER TRANSURETHRAL RESECTION OF PROSTATE.

BACKGROUND: Transurethral resection of prostate (TURP) is considered the gold standard for the surgical treatment of BPH. Irrigant fluid absorption by the patient is a potentially serious complication of TURP and can lead to dilutional hyponatremia and TURP syndrome. Other common complications of TURP include urinary tract infection and secondary haemorrhage. The objective of this study was to compare the frequency of postoperative complications (Urinary Tract infection and dilutional hyponatremia) between 1.5% glycine and sterile distilled water used as irrigant in BPH patients after TURP. METHODS: This randomized controlled trial was conducted in department of Urology, PIMS Islamabad, from August 2013 to February 2014. A total of 170 adult male patients between 50-80 years of age undergoing TURP with prostate volume more than 30cc on ultrasound. 85 patients each were randomly allocated to two groups. In group-A, glycine was used as irrigan,t solution during TURP while in group-B distilled water was used. Serum sodium levels were measured at 6th postoperative hour to look for dilutional hyponatremia. On the 15th postoperative day they were inquired about any clinical features of urinary tract infection. Also urine routine examination was performed to look for the presence of WBCs in the urine. RESULTS: Post-operative dilutional hyponatremia was observed in 13 (15.3%) patients in Group A and in 10 (11.8%) patients in group-B. The difference between both the groups being nonsignificant (p-value=0.501).Frequency of postoperative urinary tract infection on 15th postoperative day in group-A was 23(27.1%) while in group-B it was 16 (18.8%), the difference among both the groups being insignificant (p-value=0.202). CONCLUSION: Although the frequency of postoperative complications like UTI and dilutional hyponatremia was less with sterile distilled water, yet, the difference was statistically not significant.
