Why review article writing for academic journals is no more fun?

-
Review article writing for academic journals used to be fun. Putting all the available data and updates into a systematic way that would be useful for readers and students. But this seems to be a thing of the past. Publishing houses and journal editors have made this simple process cumbersome and irritating thanks to the confines of structure in which you are supposed to put forth your points.  1. This does not actually help the readers in any way. Readers want a simple article that has all the information and is comprehensive and easy to decipher. Why should readers be bothered to know on how you gathered your data and information? But journals now insist on methodology even for review article. It is a useless exercise. 2. Even if authors put the methodology, how are editors going to confirm that it is an accurate one? 3. What about the author's own expertise in the subject? If the author is an expert on the subject, the author would intuitively know what is right and wrong and pu...

Henna hair dye: safety, usefulness, and limitations.

-

 Henna is a natural temporary coloring agent obtained from leaves and tender stems of the plant,  Lawsonia imtermis. Used on skin and hair, it gives a typical brownish orange hue to the part. 

Henna and hair color

Henna gives a typical color to the hair. It hides whites but does not blacken it unfortunately. Hence it is not a versatile hair dye. It also takes many hours to produce effect. The color though natural is not permanent. But how safe is it?


Henna for hair and its safety

Since henna is natural, it is a natural tendency to think that it is a safe option to the chemical dyes for hair. But is it so really?

Henna does not penetrate into hair shaft and only remains on the hair surface. Hence it sits there preventing any hair conditioner to reach the hair cuticle. Hence hair could become lifeless and brittle with repeated use. Henna per se does not condition the hair. 

Though predominantly non-allergic, henna does have a low allergic tendency. But some cases of allergy could be due to the other components mixed in the henna-based hair dye mixture including contaminants such as nickel and cobalt. 

Henna does have some action against Malassezia furfur, the fungus causing dandruff. 

Remember 'black henna' has PPD in it in high concentrations. Hence for people allergic to it or looking for PPD free hair dyes, it is best avoided.

Why I decided to not attend Nepal Respiratory society conference 2025?

-
I am a super-specialist doctor. Hence, when I learned about the pulmonology conference in Nepal in September 2025, I thought of attending it since I was there for some other work.  But I ultimately decided against attending the Nepal Respiratory society conference. You will agree that 'the first impression is the last impression'. And my first impression about the conference and organizers, unfortunately, was bad.  Reasons: 1. Incomplete information on internet  No proper directions on internet. There was incomplete and wrong information.  2. No office When anyone makes a medical society or association, it needs to have a proper physical address, phone number, and email id. But this, Nepal respiratory society, lacked all of this.  3. Piecemeal information  Initially, the registration details had no details about registration for international delegates. Later, this was added. But again, there was improper info on it. At one place, the fees was 12k npr and a...

Dementia: problem, risks, effects, and management

-

I had met my classmate around 4 months back and informed her also about my mom's death. But in a recent email, she wrote to me that I had met her a couple of years back. She also enquired about my mom. Seeing her email, the first thought that came to my mind was: is she suffering from early dementia. I hope not. Maybe, she just forgot about the time that I had met her a few months back. Maybe because it was a hurried and surprise visit.  Nonetheless, dementia is on the rise. It affects people after 60 years of age. The increased life expectancy means that one will see more of such cases in the near future.  India has around 10 million dementia cases out of the world total of 57 million. This is a huge percentage. It affects not only an individual but the whole family. There is this individual who is physically okay but mentally absent. The person needs custodial care and it could turn out to be expensive. It is also emotionally disturbing to see your loved one in that state of...

Our planet, Earth is an important abode for every living being including plants and animals. Earth belongs to everyone. Humans are the superior living beings, but they are also the ones destroying nature and earth with their excessive deeds and misdeeds.  Climate change and global warming are also the consequence of wrong human activities in excess. Industrial revolution of the 19th century paved the way for this downhill process of environmental deterioration. It has reached a stage where excessive temperatures are giving rise to glacier and ice cap melting, sea water level rising, ecosystem disruption, weather crisis, and high rates of infections and allergies.  Also, read Dementia and its risks and management  Effective steps need to be taken promptly and on a large scale to mitigate this climate crisis and in the meantime, measures to adapt to the rising temperatures also are required to be started.  However, in all this, some people make such vague statements th...
