Peutz jehgers polyp
A hamartomatous polyp that occurs in the stomach, small and large intestines, and rarely within the esophagus, nasopharynx and the urinary tract. The Peutz-Jeghers polyps are grossly lobulated and dark. Microscopically, they have a central core of smooth muscle covered by mucosa. The smooth muscle shows tree-like branching. The question of whether or not the Peutz-Jeghers polyp is precancerous is a matter of controversy. The loss of heterozygosity on chromosome 19p (where the responsible gene LKB1 is located) suggests that the increased risk of malignancy may be due to malignant transformation from hamartoma to adenocarcinoma. --2002

A survey revealed more than 95% of vaccine preventable diseases (VPD) associated adult deaths have been reported in India. Pneumonia accounts for 39% (146/374) and meningitis for 24.3% (91/374) of invasive pneumococcal disease (IPD), causing 38,811 confirmed cases and 2,266 deaths in 2017. Insurance Information Bureau of India also stated that “certain infectious and parasitic diseases” was the top insurance claim category in 2016-17. In light of this, it’s clear: Controlling VPDs in adults through timely vaccination is crucial. What’s your take on adult vaccination in India? Should India be doing more to integrate it into routine healthcare and national health programs?
