Pulmonary hamartomas, the most common benign tumour of the lung, are usually an incidental finding and range in size between 1-5 cm in various series. There are only 11 published giant hamartoma cases in the English literature with a diameter of 8 cm or more. We report a case of a giant pulmonary hamartoma in a 54 years old man who was admitted to our hospital with complain of chest pain and progressive breathlessness since 3 months.- Double Chambered Right Ventricle with Ventricular Septal Defect

Antibiotics are emerging contaminants which affect human health, livestock, aquatic life and also resist biological wastewater treatment. Therefore, it is imperative to remove them from wastewaters. The present investigation is aimed at removal of sulfamethaoxazole (SMX) using adsorption and advanced oxidation processes (AOPs) and to determine efficacy of various adsorbents and study their adsorption kinetics. The aqueous solution of sulfamethoxazole (SMX) was treated using GAC, PAC and activated alumina. Advanced oxidation processes (AOPs) were conducted using photolysis (UV treatment) and photolysis with H2O2 (UV + H2O2 treatment). Adsorption of SMX on GAC and PAC was found to be rapid. Adsorption of SMX on GAC and PAC followed pseudo first order kinetics. PAC was found to be more effective. Removal of SMX after 120 min at a dose of 5 g/L using PAC, GAC and activated alumina was 73.4%, 34% and 15.5%, respectively. In case of PAC, only intraparticle diffusion was operating, whereas for GAC both intraparticle diffusion and surface adsorption were operating concurrently. Removal of SMX using UV treatment and UV treatment in presence of H2O2 was found to be 7.65% after 80 min and 7.67% after 110 min, respectively. Activated carbon was found to have superior behaviour as compared to activated alumina for the adsorption of SMX. Adsorption has been found more effective as compared to UV treatment and UV treatment with H2O2.Keywords

Antibiotics disposed into wastewater reach wastewater treatment plants and surface waters and act as micro-pollutants. As antibiotics pose various problems related to treatment and reuse, it is imperative to remove them from wastewater. In the present paper, adsorption studies have been carried out for removal of amoxicillin using powdered activated carbon (PAC) in a batch mode and granular activated carbon (GAC) in a continuous packed bed column. Removal of antibiotics has also been made using oxidation by H2O2. The techniques used for detection of antibiotics require elaborate analytical instrumentation. Being inexpensive and simple technique, monitoring of concentration during removal has been made using COD determination in the present work. It has been found that concentration of amoxicillin has a straight line relationship with COD. Batch adsorption using PAC shows that a maximum of 70% removal can be obtained for a 200 mg/L solution of amoxicillin using a dose of 600 mg/L of PAC. Maximum removal of 60% was obtained for a concentration of 200 mg/L of amoxicillin with a constant dose of 500 mg/L of PAC. In continuous packed bed adsorption using GAC, 90% COD removal was obtained at saturation. A maximum removal of 80% is obtained at a concentration of 200 mg/L of amoxicillin and 24.2% at 1000 mg/L through GAC column. Furthermore, oxidation removes a maximum of 90% COD using a dose 441 mM/L of H2O2 (30% w/v). Removal of COD increases from 10% to 60% on increasing dose of H2O2 from 44 mM/L to 220 mM/L. Considering removal efficiency, both oxidation and adsorption techniques have their advantages and limitations. Nevertheless, adsorption using activated carbon and oxidation using H2O2 provide simple and satisfactory methods to remove antibiotics from wastewater.Keywords

Tetramethylthionine chloride is approved by the FDA for the treatment of paediatric and adult patients with acquired methaemoglobinaemia. The objective of this research was to develop and validate an Ultraviolet (UV) spectrophotometric method for quantification of Tetramethylthionine chloride in cleaning control swab sample from manufacturing equipment surfaces. Simple, accurate and cost efficient spectrophotometric method has been developed for the estimation and quantification of Tetramethylthionine chloride which is going to be used for the evaluation of cleaning in cleaning validation. The optimum conditions for the quantitative analysis of the drugs were established. The maximum wavelength (λmax) was found to be 663nm. The percent recovery of Tetramethylthionine chloride for 50.0%, 100.0% and 150.0% were 99.13, 97.76 and 101.18 respectively. Linearity of Tetramethylthionine chloride for Validation showed a good linear relationship with Correlation Coefficient (r2) value of 0.999 was obtained. Validation was performed according to the ICH guidelines of Analytical Method Validation. The Sample Solution was chemically stable up to 36 hours. The proposed may be suitable for the Estimation and Quantification of Tetramethylthionine chloride for evaluation of cleaning in cleaning validation for quality control purposes.Keywords
