Hepatitis is a medical condition that occurs when an infected person's liver gets inflamed. There are several reasons that can result in hepatitis, including viral infections, heavy alcohol abuse, and autoimmune conditions.

 

Mostly, hepatitis is a result of an infection caused by a virus. Such a condition is called viral hepatitis. Today, we will talk about the three most common types of viral hepatitis diseases:

 ;


	
	Hepatitis a
	
	
	Hepatitis b
	
	
	Hepatitis c
	


 

Hepatitis a

Hepatitis a is a result of hepatitis a virus infection in a person and is relatively uncommon.

 ;

Regions, where hepatitis a is more common, are:

 


	
	Africa
	
	
	Asia
	
	
	Central and south america
	
	
	Eastern europe
	


 ;

How it is transmitted

Hepatitis a virus can be present in the fecal matter and blood of an infected person. Hence, it is transmitted via the oral route, involving ingestion of the virus into a person through the feces.

 

Different ways you can get hepatitis a infection are:

 ;


	
	Having in-person contact with a hepatitis a-infected patient
	
	
	Sexual contact with a person who hosts the virus
	
	
	Consuming contaminated food or drink
	
	
	Eating undercooked shellfish
	
	
	Being near contaminated toilets and diaper changing areas
	


 

Hepatitis b

Hepatitis b is caused by the hepatitis b virus.

 ;

Regions, where hepatitis b is more common, are:


	
	Western pacific region
	
	
	African region
	


 

How it is transmitted

You can contract hepatitis b virus through direct contact with blood or bodily fluids of hepatitis b infected person.

 ;

Different ways you can get hepatitis b infection are:

 


	
	Sexual contact with someone with hepatitis b virus infection
	
	
	Sharing injections and other tools
	
	
	Born to hepatitis b infected parent
	
	
	Direct contact with blood of an infected individual
	
	
	Sharing personal belongings and toiletries like razors or nail clippers.
	


 ;

Hepatitis c

Hepatitis c occurs by the infection caused by hepatitis c virus.

 

Regions, where hepatitis c is more common, are:


	
	Eastern mediterranean region
	
	
	European region
	


 ;

How it is transmitted

Hepatitis c virus is spread through blood and other bodily fluids.

 

Different ways you can get hepatitis c infection are:

 ;


	
	Sharing injections
	
	
	Born to hepatitis c mother
	
	
	Sexual contact with an infected person
	
	
	Piercing or tattooing with unsterilized equipment
	
	
	Injuries with needles pr blades
	
	
	Sharing razors, or toothbrushes
	


The A, B and C of Hepatitis

World sickle cell day is observed annually on the 19th of june to raise awareness of sickle cell-related diseases. It is observed to increase people's knowledge and the understanding required to face the challenges posed by the disease.


 

What is sickle cell disorder (scd)?

Sickle cell disorders or sickle cell diseases are genetic blood disorders that cause an abnormality in the red blood cells. The rbcs turn into sickle-shaped cells that stick together and block the blood flow in the body.


 ;

Types

There are four major classifications of sickle cell diseases-


	
	Hemoglobin ss disease
	
	
	Hemoglobin sc disease
	
	
	Hemoglobin sb+ thalassemia
	
	
	Hemoglobin sb 0 thalassemia
	



 

Symptoms

One can start noticing symptoms of sickle cell in a patient at around 6 years of age. However, they can differ from person to person. Some of the most typical symptoms are-

 ;


	
	Anemia
	


A shortage of red blood cells occurs due to the excessive early dying in 10-20 days. It leads to an oxygen shortage in the body.


	
	Excessive pain
	


Blockage of blood flow due to the change in shape leads to periodic cycles of pain in the body.


	
	Swelling in the body
	


As the blood circulation becomes irregular, swelling becomes a regular phenomenon.


	
	Infections
	


Sickle cell can be damaging to the spleen. It increases the risk of ailments in the body that can be prevented only by antibiotics.


	
	Delayed puberty
	


Oxygen and nutrients carried by the blood are required for growth. As a reason, irregular blood flow can lead to slow growth or delay in puberty.


	
	Vision issues
	


Infected blood vessels carrying blood to the eyes can cause damage to the retina. It can lead to visual problems.


 

Traits and treatment

As sickle cell is genetic, it is suggested to take a test that can detect any trait of the disease. It can prevent any life-threatening risks to the newborn. However, we don't have a complete cure for sickle cell disorders. There are preventive measures that reduce the adversity of the disease to an extent. Procedures like blood transfusions help greatly in minimizing the effects of the disorder.

World Sickle Cell Day: Know All About Sickle Cell Disease

What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.
 

What Are The Different Types Of Sickle Cell Disease?

Air pollution affects the overall health of a human being. Whether it comes out of exhaust fumes from cars and factories or smoke from burning stubble air pollution, it is a cause of major concern. The effects of this can be seen in the growing number of asthma and other respiratory diseases. These diseases affect adults and children alike, however, it is the younger generation and elderly people who are more susceptible. Hence, it is extremely important to care about the quality of the air you breathe in. 


 ;

What is the significance of the air quality index (aqi)?

The air quality index is a visual representation of pollutant levels in the air around you. A quick glance at this colour coded map can tell you if the air outside your home is likely to harm you or not. The code is broken down into 6 levels ranging from green which signifies minimal impact to red which marks pollution levels that can harm a healthy person and seriously impact those who are already ill. The higher the aqi, the higher the level of air pollution.

 

What are the steps to reduce air pollution?

Simply talking about how there need to be stricter laws about car emissions and the burning of waste will not help you. Here are a few things you can do to protect yourself and your family from the ill-effects of air pollution.


	
	Carpool: exhausts from cars and other vehicles are one of the biggest causes of air pollution. Do your part to reduce air pollution by restricting the amount you use your car. Try taking public transport to work or carpooling with colleagues. Similarly, avoid making individual trips every time you need something from the market. Make a list and when it s long enough, then step out.
	
	
	Limit indoor pollution: do not smoke indoors. When cooking, keep the exhaust fan on so that the smoke produced does not collect indoors. Avoid spraying air fresheners etc. While they may temporarily make the air smell fresh, in the long run, they contribute to air pollution.
	
	
	Use public transport try to use public transport and avoid the use of personal vehicles.
	


How to protect yourself from air pollution


	
	Refrain from morning walks routines to later hours.
	
	
	Use n95/99 face masks whenever you step out.
	
	
	Use air-purifying plants to purify the air around your surroundings.
	
	
	Ventilate your kitchen, and bathroom to keep yourself away from air pollution.
	
	
	Restrict outdoor activities for kids if there is a high level of air pollution
	
	
	Use air-purifiers in your surroundings.
	
	
	Try to take steam with a few drops of eucalyptus oil every day.
	
	
	Keep your car s environment fresh.
	
	
	Ventilate your home, open your windows and doors and allow the air to circulate during mid hours.
	
	
	Eat jaggery (aka gurr) to flush out pollutants from your lungs.
	
	
	Consume a diet rich in vitamin c, omega fatty acids
	


Hence, the other way to cut down this pollution is by bringing significant lifestyle changes in our daily living. Cutting down the number of diesel and petrol vehicles can also prove helpful. People should shift to cng and electric vehicles for daily commuting. These efforts, if practiced on a regular basis, can bring a huge decrease in pollution.

Air purifiers can also be a healthy option for indoor purposes.

Why Should You Care About Air Quality?

A brain tumour is a life-threatening situation. Most of the symptoms of the brain tumour are alike, but not all tumours are malignant. The most common type of brain tumour is meningioma. You may even don t need surgery in this case as they are really not dangerous or life-threatening.

 

Here are some of the facts you should know about meningioma:

 ;

Meningioma can develop in numerous locations

 

Cells in the meninges, the lining of the brain and spinal cord, give rise to these tumours. In fact, they are not brain tumours at all, because they are not caused by the altered brain cells. ;

However, they continue to grow inside your sull, indicating that you should now take immediate steps. Meningioma can produce brain tumour symptoms if it grows or creates swelling that presses against the brain or other tissues in the skull.

 

Meningioma symptoms vary depending on the size and location of the tumour

 ;

Meningioma can cause vision-related issues, headaches or seizures which are all common signs of a brain tumour. A headache, even a strong one, is seldom an indication of meningioma or any other type of brain tumour on its own. 

 ;

Other tumour sites can influence your sense of smell, vision, hearing and even the pituitary gland s function.

 

Meningioma diagnosis usually happens when the doctor is looking for some else

 ;

The discovery of a tumour on a ct scan or mri while investigating the patient for another cause, such as a head injury or another neurological condition, is called an accidental diagnosis. When a doctor identifies a meningioma, you will undergo additional testing to determine how the tumour will behave. A neurosurgeon will decide whether to remove the tumour or just monitor it to see whether it grows based on these findings. 

 ;

Majority of meningioma does not spread

 

Being diagnosed with meningioma, especially a large one, might be shocking, but these tumours are usually non-dangerous. Tumour cells are unlikely to spread to other sections of the body as a result of this. ;

Meningiomas, on the other hand, can grow silently for years without creating any difficulties and they can grow to be enormous.

 

Things You Should Know About Most Common Brain Tumours

World environment day is celebrated annually on 5th june. This day encourages awareness and action for the protection of our environment. It raises the problems facing our environment such as plastic pollution, air pollution, illegal wildlife trade, sea-level increase, sustainable consumption, and food security, among others. 

 ;

World environment day is a reminder for us to pause and reflect on our actions and their subsequent consequences on the planet. 

 ;

When was the world environment first celebrated?

The day was first observed in 1974 in the city of spokane in the usa.

 

History of world environment day (wed)

1972- the un general assembly established world environment day on the 1st day of the stockholm conference on the human environment. ;

1974- the first" world environment day" was held with the theme" only one earth. 

1987- the idea for rotating the center of these activities by selecting different host countries began. ;

 

Why is world environment day celebrated? ;

For a healthy life, the environment plays an important role. It provides us with air, food, etc. The environment is like our neighborhood, its surrounding conditions affect us and also modify development. It is really necessary to address the environmental issues like deforestation, increasing global warming, pollution, wastage and losses of food, etc. Currently, our earth is experiencing a triple planetary emergency: 


	
	Pollution is poisoning our air, land and water. ;
	
	
	Climate is heating up too quickly
	
	
	Habitat loss
	


The deteriorating environmental conditions worldwide had already raised alarms in academic circles, among scholars studying its conditions. However, general masses seemed oblivious to changes that were not directly affecting them.

The world environment day is structured in a manner that allows one country to take up the responsibility of selecting the theme and hosting the key celebrations each year. 

Let's all come together and ensure this unique and beautiful planet remains a comfortable home for humanity.
