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.

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.

World Environment Day: What Is World Environment Day And Why It Is Celebrated? 

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

Type 1 diabetes occurs when your pancreas is unable to produce enough insulin to keep the blood sugar ;levels under control. The condition, if not managed properly, can lead to related health disorders and complications, both long-term and short-term.

Health problems arising from type 1 diabetes

Type 1 diabetes can have severe effects on your eyes, kidney, nervous system, and heart health. The most common ailments associated with type 1 diabetes may include the following-

1. Diabetic retinopathy

Diabetic retinopathy is a disease of the eyes, which occurs when the blood vessels in the retina (tissue present at the back of your eyes) are damaged. The walls of the retina gradually weaken from increasing blood pressure and blood sugar levels, and this leads to leakage of blood or fluid into the nearby tissues.

Early symptoms of diabetic retinopathy include-


	
	Blurred vision
	
	
	Floaters
	
	
	Difficulty perceiving colors
	


2. ;Diabetic neuropathy

Diabetic neuropathy unfolds when the nerves are damaged due to type 1 diabetes. The condition mostly affects your feet and legs. Reduced blood circulation due to high blood glucose impedes normal wound healing in the extremities, hence, even a minor bruise ;can develop into a permanent injury.

Symptoms of diabetic neuropathy are-


	
	Numbness
	
	
	Reduced sensation
	
	
	Severe, debilitating pain in the extremities
	


3. Diabetic nephropathy

Also known as ;diabetic kidney disease, the condition is a slow deterioration of the kidney and its ability to function properly. In severe cases, where the levels of blood glucose are extremely high due to type 1 diabetes, diabetic nephropathy can ultimately result in kidney failure ;or end-stage renal disease (esrd).

The following are the symptoms of diabetic nephropathy-


	
	Dark urine
	
	
	Swollen ankles, feet, eyes, or hands
	
	
	Shortness of breath
	


4. Cardiovascular diseases

Cardiovascular diseases refer to a range of heart conditions including blood clots and diseased blood vessels. High blood glucose levels resulting from type 1 diabetes can contribute to the deposition of fat in the walls of the blood vessel. Over time, this may restrict the flow of blood and put you at risk of cardiovascular disorders such as coronary artery disease, stroke, or even ;heart attack.

Symptoms of cardiovascular diseases widely vary, ranging from palpitations ;to chest pain. Sometimes, such a condition may not exhibit any symptoms at all.

Type 1 diabetes complications are related to poor management of blood glucose. The best way to monitor the condition and control the symptoms is to get in touch with your doctor. A specialist in this field can prescribe the correct treatment and help prevent the onset the related health disorders.

Complications Associated With Type 1 Diabetes

Urinary tract infections (uti) can occur anywhere in the urinary system   the bladder, kidneys, urethra, and ureter. Most of these infections affect the lower part of the urinary system   urethra and the bladder.

An infection ;confined to the bladder can be frustrating and painful. You may experience pain during urination, and pus or blood in the urine. However, the condition becomes worse if the infection spreads to the upper part of the urinary system, particularly to the kidneys, triggering nausea, ;vomiting, and severe pain in the back.

If uti is left untreated, it can potentially lead to kidney damage   a condition known as pyelonephritis.

How does untreated uti affect the kidneys?

Untreated urinary tract infections can cause the kidneys to swell up and damage them permanently. The infections initially begin in the lower tract of your urinary system. Then the bacteria slowly enter your body through the urethra and begin multiplying and spreading up to the bladder. The bacteria eventually travel to your kidneys through the ureters.

Some people are at higher risk for kidney damage due to urinary tract infections. This includes  


	
	Pregnant women
	
	
	Elderly people
	
	
	People with kidney problems
	
	
	Someone with a weak immune system
	


Signs to watch out for

An untreated infection in the bladder that has spread to the kidneys is associated with symptoms, such as the following  


	
	Chills and ;fever
	
	
	Vomiting and nausea
	
	
	Pain in either side of your lower back
	


You should visit a doctor right away if you notice the above uti symptoms. The condition requires immediate medical intervention in order to prevent damage to your kidneys.

Symptoms of painful utis can be managed by combining medications and lifestyle remedies. Consult a specialist to diagnose the condition early and seek appropriate treatment to avoid complications.
