Evaluation of water quality index for drinking purposes for river Netravathi, Mangalore, South India
No full textAn attempt has been made to develop water quality index (WQI), using six water quality parameters Dissolved oxygen (DO), Biochemical oxygen Demand (BOD), Most Probable Number (MPN), Turbidity, Total Dissolved Solids (TDS) and pH measured at eight different stations along the river basin. Rating curves were drawn based on the tolerance limits of inland waters and health point of view. Bhargava WQI method and Harmonic Mean WQI method were used to find overall WQI along the stretch of the river basin. Five point rating scale was used to classify water quality in each of the study areas. It was found that the water quality of Netravathi varied from Excellent to Marginal range by Bhargava WQI method and Excellent to Poor range by Harmonic Mean WQI method. It was observed that the impact of human activity was severe on most of the parameters. The MPN values exceeded the tolerable limits at almost all the stations. It was observed that the main cause of deterioration in water quality was due to the lack of proper sanitation, unprotected river sites and high anthropogenic activities

Cysticercosis of midbrain presenting with fluctuating ptosis
No full textFluctuating ptosis is usually caused by Myasthenia gravis. There are a few case reports of central causes of fluctuating ptosis. A 58-year-old man presented with fluctuating ptosis of one year duration. He was diagnosed as having ocular myasthenia and investigated. On evaluation, his electrophysiological tests revealed negative decremental response and results of neostigmine test was negative. During follow-up, patient developed headache. Imaging of the brain revealed midbrain cysticercosis granuloma. The focal encephalitis and edema was responsible for fluctuating ptosis. It is therefore essential to be aware of conditions that cause such pseudomyasthenic features. Patients with ptosis need to be evaluated for other rare central cause especially when neostigmine test is negative

Studies on the occurrence of enteric bacteria in the estuarine waters along the Mangalore coast
No full textOccurrence of enteric bacteria in water, sediment and shellfishes of Mulki, Pavanje, Gurpur and Netravathi estuaries of the Mangalore coast is reported. 70 water samples, 71 sediment samples and 37 shellfish samples were analysed in 18 months. Total bacterial load in sediment and shellfishes was found to be more than that in water samples. The total bacterial load was not very high. However, enterococci, particularly coliforms in sediments, water and shellfishes were found to be quite high, indicative of faecal pollution. The incidence of Salmonella spp. was recorded in all the estuaries except the Mulki estuary
