SENSITIVITY OF FECAL IMMUNOCHEMICAL TEST IN DETECTING COLORECAL NEOPLASMS
Cumulative evidence has confirmed that FIT is a sensitive screening test with the potential to decrease the mortality of CRC when it is implemented at the population level. The evaluation of FIT performance is an important first step before implementation of the preventive strategy; however, one positive test is not equal to one cancer detected. Many other important issues complicate the screening process. To improve the effectiveness on the population level, a step-by-step evaluation of the screening process is needed.

REDEFINING THE CAUSE FOR THE PERSISTENT INFECTION OF ENDODONTICALLY TREATED TEETH.
Aim: To address the cause of persistent infection of root canal treated teeth. Materials and Methods: 60 human single-rooted teeth divided into three groups. Group I (control group): no access opening and one-third of the apical root sealed using varnish. Group II: no preparation of teeth samples. In group III, apical root cementum was exposed to lactic acid and roughened using diamond point to mimic apical resorption. In group II & III E. faecalis broth was inoculated in the root canals and apical one-third of the tooth was immersed in the broth for 8 weeks with alternate day refreshment followed by biomechanical preparation, obturation and coronal seal. Apical one-third of all teeth samples were again immersed in the broth for 8 weeks to mimic secondary infection. The teeth were split into two halves and observed under confocal microscope. Results: E. faecalis penetrated 160 μm deep into the root cementum in group III samples and only showed adhesion in group II samples. Conclusion: Adhesion and Penetration of E. faecalis into the cementum could be the reason for persistent infection.

HYPERTENSIVE RENAL DISEASE – SHOULD WE TREAT IT BY ENDOVASCULAR SURGERY?
The treatment of renal hypertension grounded in our clinical findings or when there is change in flow, with increase in velocity, we perform diagnostic angiography and angioplasty if necessary at the same operative time. The treatment of renovascular hypertension is effective when we treat the main branch of the renal artery; prevents the loss of organ function, decreases renal overload and prevents the patient from getting into a dialysis program.

ANTHRACOSIS: CAUSE OF BLACK PATCH IN TRACHEA AND BRONCHIAL TREE
Anthracosis is black pigmentation of tracheo-bronchial tree evident on bronchoscopy. We studied 30 cases with and 53 controls without anthracosis. We found that anthracosis patients are more likely to be middle aged to elderly females with history of active or old pulmonary tuberculosis and evidence of fibrosis on CT chest.
