We describe a most unusual case of a 40-year-old male who presented with audible popping sounds emanating from his left ear canal. The process of identifying the source of the sounds and treating the underlying cause is presented in detail.

Pharmaceutical industries and effluents of sewage treatment plants are the main sources of residual pharmaceuticals in water resources. These emergent pollutants may adversely impact the biophysical environment. Pharmaceutical industries often generate wastewater that changes in characteristics and quantity depending on the used manufacturing processes. Carbamazepine (CBZ), {5Hdibenzo [b,f]azep...

Among all the aromatic compounds phenol is the major constituent of soil contaminated form many industries. Toxicity of phenol is well recognized for human as well as environment. In future, microbial system is the potential tool to deal with environmental pollutants like phenol. In the present study, an aerobic bacterial culture was isolated from oil contaminated soil by enrichment technique a...

The methods of treatment of wastewater briefly discussed. Special attention has been paid to the biological treatment mentioning the drawbacks of the traditional methods. The relative advantages of var...

BACKGROUND Non-Hodgkin's lymphomas (NHLs) have been linked to proximity to industrial areas, but evidence regarding the health risk posed by residence near pollutant industries is very limited. The European Pollutant Emission Register (EPER) is a public register that furnishes valuable information on industries that release pollutants to air and water, along with their geographical location.Thi...

OBJECTIVE To determine the cellular mechanism that allows subretinal hemorrhage to cloud the vitreous. METHODS We simulated subretinal hemorrhage in a rabbit model by injecting autologous blood beneath the retina. At the first appearance of a cloud in the vitreous a vitrectomy was performed and using a surgical microscope, the retina was searched for breaks. After enucleation and fixation, th...

Phenolic derivatives are used as raw materials in textiles, pulp and paper, petrochemical, pharmaceutical, oil-refineries and leather industries. These heterocyclic aromatic chemicals are among the most frequently found pollutants in industrial effluents. Since these compounds are toxic either through ingestion, inhalation or contact even at low concentrations, biodegradation of the effluent is...
