Alkaptonuria is a rare hereditary disease with a defective enzyme that results in increased homogentisic acid levels in the body. Homogentisic acid accumulates in multiple body parts and initializes tissue damage. Clinical manifestations such as pigmentation of the skin areas and joint destruction result in ochronosis. Nitisinone decreases serum and urinary homogentisic acid levels, improving morbidity by preventing and slowing the progression of alkaptonuria. Nitisinone-induced hypertyrosinemia causes keratopathy and mental ill effects, which can be managed by diet restriction and regular check-ups. A personalized approach is required for treatment by nitisinone. Low-dose oral nitisinone is associated with overall good results and a better safety profile., Competing Interests: All authors declared no conflict of interest., (© 2022 The Authors.)

Poliomyelitis is a viral disease that causes acute paralysis, muscle weakness and autonomic dysfunction. It primarily affects children under the age of five. It is mainly transmitted via the feco-oral route, through contaminated water. As of the year 2022, Pakistan remains one of the two countries where polio is still endemic, the other being Afghanistan. Numerous myths and misconceptions regarding the polio vaccine, lack of awareness and proper governance, terrorism and difficult access to remote areas due to poor infrastructure are just some of the reasons why polio remains endemic in Pakistan to this day. Therefore, the government should take measures to ensure the safety and wellbeing of health care workers, as well as spread awareness regarding the importance of polio vaccines, while addressing the myths and misconception regarding said vaccines., Competing Interests: All authors declared no conflict of interest., (© 2022 The Author(s).)
