When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. There are various types of brain tumours that exist. Some of the brain tumours which exist are malignant or cancerous while other may be non-cancerous. A brain tumour can begin in any part of the brain and spread to other parts of the body or vice-versa. The growth rate of brain tumours is different for each individual suffering from it. As per studies, every 2 in 1, 00, 000 people are said to be affected by a brain tumour in india. However, it may come as a relief to some as not all brain tumours are cancerous or life-threatening. Some are benign tumours and seldom pose any threat to the affected individual.

 

Types of brain tumor

Brain tumours may be primary or secondary.

Primary brain tumour

In this type of brain tumour, the abnormal mass of cells that originated in the brain does not metastasize to the other organs. Based on their location in the brain, the primary brain tumours may be of the following types.


	
	Gliomas: one of the most common types of primary brain tumours, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include astrocytomas (originates in the cerebrum of the brain), glioblastomas (these tumours form from the astrocytes which form the supportive tissues of the brain), ependymoma (these develop from the ependymal cells which are present within the cns), oligodendrogliomas (these tumours are found to arise from the oligodendrocytes).
	
	
	Schwannomas: also called acoustic neuromas, these primary brain tumours form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
	
	
	Meningiomas: these types of tumours are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
	
	
	Primitive neuroectodermal tumours (pnets): primitive neuroectodermal tumours (pnets) are rare malignant tumours that originate from the fetal (embryonic) cells in the brain.
	
	
	Pituitary adenomas: as the name suggests, these tumours arise from the pituitary gland located at the base of the brain.
	
	
	Medulloblastomas: common among children, these malignant primary tumours develop in the brain (lower back) and gradually spread via the spinal fluid.
	


Other types of primary brain tumours include craniopharyngiomas and germ cell tumours.

Secondary brain tumours ;

Unlike the primary brain tumours, these tumours have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. Secondary brain tumours are found to be more common.

 

What Are The Different Types Of Brain Tumours?

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

Hepatitis is a condition that affects the liver by causing inflammation which is a common outcome resulting from a viral infection. While different types of hepatitis diseases are caused by different causes, there are some reasons like medications, toxins, alcohol, and drugs that are typically known.

 

Types

The five common types of viral hepatitis are hepatitis a, b, c, d, and e.

 ;


	
	Hepatitis a
	


Hepatitis a is the result of an infection caused by the hepatitis a virus. This type of hepatitis is an acute disease.

 


	
	Hepatitis b
	


The hepatitis b virus causes hepatitis b. This is often a chronic disease that lasts longer.

 ;


	
	Hepatitis c
	


Hepatitis c comes from the hepatitis c virus. It is one of the most common bloodborne infections in the world. It is a long-lasting condition.

 


	
	Hepatitis d
	


This is a not so commonly found form of hepatitis that only occurs in hepatitis b infected people. This virus not only causes liver inflammation but also cannot be contracted without an existing hbv infection.

 ;


	
	Hepatitis e
	


Hepatitis e is waterborne. Hepatitis e virus infection is responsible for it. It is generally acute but can be severely chronic for pregnant women.


 

Causes of viral hepatitis

It is true that different types of viral hepatitis infections are caused by distinct modes of transmission. Here are the causes of a hepatitis infection:

 ;


	
	Hepatitis a- when a person is exposed to the hepatitis a virus through food or water.
	


 


	
	Hepatitis b- when an individual comes in contact with hepatitis b virus through the transmission of bodily fluids like blood, semen, etc.
	


 ;


	
	Hepatitis c- when someone gets infected with the hepatitis c virus through the contamination of bodily fluids.
	


 


	
	Hepatitis d- when a person is exposed to hepatitis d virus-infected blood, it causes this disease.
	


 ;


	
	Hepatitis e- when a person comes in contact with the hepatitis e virus through water or food.
	


 

Causes of non-viral hepatitis

Although hepatitis is commonly caused due to an infection, other factors can also be reasons to cause hepatitis.

 ;

Alcohol

Excessive alcohol can lead to liver damage, causing inflammation. It can also be called alcoholic hepatitis. The alcohol impacts the liver cells directly. Moreover, it can also cause cirrhosis or even permanent liver failure.

 

Autoimmune system response

In rare cases, the immune system of a person attacks the liver itself. It leads to inflammation that can be mild to severe according to the infection. Moreover, it s more common in females than in males.

How Is Hepatitis Caused And Some Common Types?

People suffering from sickle cell disease (scd) usually start showing symptoms very early. They can appear to show up even during the first year of life. Symptoms of a sickle cell vary from one person to another and can be mild to serious depending on the condition.

 

Sickle cell disease is a health condition that worsens with time. Despite the absence of any full-proof solution, some treatments prevent further complications. These treatments can help patients receive aid for a lifetime. Simply said, sickle cell diseases can be managed medically.

 ;

Treatment

Treatment in a sickle cell patient depends on the severity of the symptoms. Preventing complications and relieving pain is the primary aim of the diagnosis. They can range from medications to blood transfusions.

 

Concerns

Some of the concerns that need to be taken care of during the treatment of scd are-

 ;


	
	Prevent painful scenarios
	


A painful episode or sickle cell crisis can be avoided by consuming sufficient fluids, wearing warm clothing, and staying away from sudden temperature changes.

 


	
	Avoid infections
	


Children with sickle cell anemia are made safe from infections by using penicillin. Adults with anemia might need to take penicillin all their lives. Doctors should ensure that all vaccinations in children and adults are periodically done to avoid any infections. However, during the covid-19 pandemic sickle cell patients should take extra care.

 ;

Medications

While there can be numerous ways to manage sickle cell treatment, medications help in a significant way. Some of the prescribed medicines are-


	
	Hydroxyurea- it reduces the frequency of sickle crises. Pregnant women should stay away from this according to experts.
	
	
	Crizanlizumab- this drug injected into the patient can help reduce the sickle crises in adults and children over the age of 16.
	
	
	Voxelotor- it is an oral drug used in children over 12. It lowers the risk of anemia by improving blood flow.
	
	
	Pain-relievers- narcotics to prevent excessive pain can also be used during the treatment.
	


 

Surgical procedures


	
	Blood transfusion
	


It is used to prevent stroke and other related complications in patients. This can increase the number of red blood cells in the body that can help reduce the symptoms.

 ;


	
	Stem cell transplant
	


It is also called a bone marrow transplant and is used to replace affected bone marrow with a healthy one. This procedure is carried out between matched donor and recipient. Although it is a known cure for sickle cell disease, various risks involved make it a less used practice.

 

Can Sickle Cell Be Cured?

Environmental factors play a quintessential role in affecting our health. Fresh air, fresh food and fresh water, not only strengthen our body and mind but also make our life worth living. Contrary to this bad environment hampers the quality of life. This is the main reason why people from hill stations or the countryside seem to be healthier than those living in polluted urban cities. Following are the environmental factors that affect your health:

Polluted air

The health effects of polluted air are several. Not many people know that one-third of the deaths are caused because of strokes, lung cancer and heart failure. Air pollution is the chief reason behind these chronic ailments. The other life-threatening diseases caused by polluted air is- asthma or bronchitis. Smoke from machines, vehicles outside, and stoves, the burning of fuels inside can cause breathing problems and wheezing. 

Dirty environment

A dirty environment often leads to the breeding of insects and bacteria that become carriers of life-threatening diseases such as dengue, typhoid, diphtheria, malaria, and so on. Most of the diseases mentioned here are caused by mosquitoes that thrive on stagnant water.

Toxic food ;

The environmental quality of a region has a direct impact on the food produced in that area. Both vegetarian and non-vegetarian food faces the danger of becoming toxic if the environment it is being grown in is polluted. For eg- chemical wastes that are often dumped in water bodies cause the seafood in that area to become highly toxic.

Chemical pollutants

Cancer nowadays is becoming a household disease. The major reason behind this is that technological development has brought new categories of pollutants. Many of these contain chemicals and compounds that are carcinogenic in nature. This ultimately leads to the development of cancer in most people. 

Climate change and natural calamities

Change in climate disrupts the functioning of nature in many ways that further impact the health of humans. These changes include- the natural temperature of the planet, heavy rainfalls and sandstorms. The numerous impacts of climate may result in a high risk of nervous and respiratory diseases. ;

Hence protecting the environment is extremely important for the life of a human being. The change will come after taking small steps. Numerous small steps can really make a difference.
