Acoustic neuroma is the development of noncancerous and slow-growing tumors on the main, vestibular nerve that travels from the inner ear to the brain, connecting the two organs. They are also known as vestibular schwannoma, as it arises from Schwann cells covering the vestibular nerve. It rarely grows rapidly or attains a large enough size that can press against the brain and interfere with the vital functions of the brain. Since the tumor is benign, the patient can be assured that it won t spread to the other parts of the body; however, they can grow large enough to disrupt the normal function of the body.

The pressure from the acoustic neuroma on the main nerve can cause loss of hearing, a constant ringing in the ear and unsteadiness. As per a report published by the Acoustic Neuroma Association, 1 out of every 50,000 people suffers from this condition.

Risk factors for acoustic neuroma
Acoustic neuroma does not have quite as many risk factors. The only established risk factor for acoustic neuroma is having a parent who suffers from the rare genetic disorder neurofibromatosis 2 (NF2). However, having said that, neurofibromatosis 2 (NF2) accounts for only 5 percent of the reported cases. In most of the cases, it has been found that the tumors appear spontaneously without any indication of a family member having this disease or any medical history of the same.

The development of noncancerous tumors on the ear nerves as well as other nerves in the body is scientifically supported as a characteristic indication of neurofibromatosis 2 (NF2). Neurofibromatosis 2 (NF2) is also termed as an autosomal dominant disorder, which indicates that the mutated gene can pass from just one parent. Each of the children has a fifty-fifty chance of inheriting the disease.

However, scientists and doctors have failed to identify why specific people get these tumors. They have reached a generic conclusion about the risk factors, which may include:

Loud noises near the ear.
A parathyroid neuroma, which is a similar benign tumor of the thyroid.
A chance of exposure to low levels of radiation in the childhood.
How to diagnose the risk factors for acoustic neuroma?
If you are experiencing loss of hearing or other neurological symptoms, try to keep track of them. Later on, mention them to your doctor for a proper diagnosis. A detailed history of the symptoms will help your doctor. Your doctor will perform a hearing test to check whether you have an acoustic neuroma. Then the doctor may perform a brainstem auditory evoked response tests along with an electronystagmography to detect any changes in eye movement, caused due to the inner ear. MRI and CT scans are also quite common diagnoses methods for acoustic neuroma.

Acoustic Neuroma - What Are The Risk Factors?

Surgery to remove abnormal growths of the brain, peripheral nervous system or the spine or any disorder can be tricky because the brain and the skull that shields it are complex areas. In the old days, open surgery was the only way to access the brain or spinal cord. But, with the invention of laparoscopy, keyhole surgery to treat neurological issues is gaining ground.

What is Neuroendoscopy? 
Neuroendoscopy is a surgical procedure that is favoured by doctors and patients alike because it is minimally invasive.
Before the surgery, you will be administered general anaesthesia so that you will be unconscious during the entire duration. During the surgery, the surgeon will drill a minute hole into your skull just above the eyebrows. You skull also has two natural openings. That is why the surgeon may make use of the nose or the mouth to access the region that needs to be operated upon.

Neuroendoscopy is useful because -

  It lets the surgeon reach regions that are not accessible with open surgery
  The tumour can be removed without any damage being done to surrounding tissues

An endoscope is a delicate device with a high-resolution camera mounted on it. There is an eyepiece on the other end. The device is also fitted with a light. When it is inserted into the brain, it lights up the passage and the eyepiece allows the surgeon to take a look inside. The camera sends a live feed of the path it is traversing and this guides the surgeon. When the tumour is reached, it is gently removed with other surgical instruments that too were inserted through the cavities or the drilled hole.

Benefits of Neuroscopy -
There are several advantages of relying on laparoscopy -

  The patient endures less pain
  Fewer chances of infection
  Faster recovery
  Very little scarring of tissues

Which Disorders call for Neuroendoscopy?
Any of the following disorders can be put to rights with a neuroendoscopic surgery -

  Pituitary tumours
  Rathke s cleft cysts
  Pineal area tumours
  Ventricular tumours
  Skull base tumours
  Brain inflammation triggered by an infection
  Chordomas
  Cerebrospinal fluid fistulas
  Trigeminal neuralgia
  Cerebral aneurysm

After Surgery-
Once you undergo the neuroendoscopic surgery, you will have to be rehabilitated so that your condition can be monitored round the clock. Neuroendoscopy is a state of the art clean and efficient surgery that is beneficial to both surgeons as well as the patients.

Brain tumor refers to the development of unusual cells in the brain or around the nearby tissues and structures. Pediatric Brain Tumor means the development of these unusual cells in the brain of children. There are two types of brain tumors: Benign or non-cancerous and malignant or Cancerous. Tumors like ependymoma and medulloblastoma are quite common among children. The treatment of the tumor is determined by its severity, type, location, age, and overall health of the child. The treatment of Brain Tumor in children is different from the adult s treatment. One should ensure to consult with the pediatrician with the specialty in cancer and neurology. Brain Tumors in children are Primary Brain Tumors that develop in the brain or nearby tissues. This Primary Brain Tumor develops when the usual cells have DNA mutations or alterations. The alterations in the DNA permit the cells to develop and distribute or split with an increased rate and destroy the healthy cells. This leads to the development and collection of unusual cells forming a tumor. In most Primary Brain Tumor cases, the cause is not clear. Children with a family history of the genetic syndrome and Brain Tumor are more prone to the problem.

Symptoms-

The symptoms of the Pediatric Brain Tumor depend upon the severity, location, and type. There are a number of symptoms that are really common and are shared by other diseases. Other than this, there are symptoms which are possibly the signs of Brain Tumor among children. Adults and parents should consult a doctor if they find their children having the symptoms and signs for an unusual time.

Hearing issues

Frequent and severe headache

Fuller fontanel (soft spot) on the baby s skull

Vomiting or nausea

Behavior changes

Seizures

Sudden vision problems like double vision

Abnormal or strange eye movement

Increased heaviness or pressure in the head

Irritability

Slurred speech

Difficulty in swallowing

Weakness

Loss of appetite

Drooping on one side of the face

Difficulty feeding in babies

Loss of sensation on one side of the body

Imbalance or difficulty in balancing

Difficulty in walking

Diagnosis-

The diagnosis for the Pediatric Brain Tumor includes many lab tests. The doctor may initiate with some neurological examination like hearing, vision, reflexes, balance, and coordination. Any abnormality in these tests will lead to further examinations. There are some imaging tests that are used to determine the size and location of the tumor in the brain. These tests include MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), and CT (Computerized Tomography). After the confirmation of the presence of a Brain Tumor, the specialist will further move to the Biopsy. It includes the removal of a sample tissue for analysis or testing. The type of biopsy that will be performed on the patient depends upon the location of the tumor. Other than the biopsy, the tumor tissue can be examined for molecular basis and genetic mutations. After that, Drug therapy can be designed according to the individual s requirements. It is important for the doctor and the patient to know if the tumor has been spread through cancer in other parts of the body. If it is true, then the doctor will perform more tests and examinations to know the root and initial location of cancer for further treatment.

Treatment-

The treatment of the Pediatric Brain Tumor is determined by the severity, location, size of the tumor, and age and health of the child. There is a number of treatments available with modern technology but their usage depends upon the patient s requirement.

Surgery that is used when the location of the tumor is approachable via surgery. When the brain tumor is small, it can be completely removed by the surgery. But when the tumor tissues are located nearby sensitive areas of the brain, then the surgery becomes risky and maximum tumor tissues are tried to be removed through surgery. The risk of the surgery depends upon the location of the tumor. An example can be vision loss if it is anywhere near the nerves connected to the eyes.

Targeted Drug Therapy helps to destroy the abnormalities of the cancer cells resulting in the destruction of the cancer cells.

Radiation therapy is used to kill the tumor cells by using high-energy beams. Radiation therapy can either be given by an external machine (external beam radiation) or in exceptional cases, radiation is positioned within the body (brachytherapy) near the tumor.

Chemotherapy includes the consumption of drugs to destroy the tumor cells. These drugs can be consumed in tablet form but for children, the drugs are mostly injected (intravenous chemotherapy).

Stereotactic Radio Surgery includes various radiation beams to perform extremely focused radiation therapy to destroy the tumor cells located in a small part.

Proton Beam Therapy carries higher targeted radiation doses to the tumor cells with minimum exposure of radiation to the healthy cells and tissues. It decreases the chance of development of fresh cancer cells.

Take Away-

Pediatric Brain Tumor is the development of unusual cells in the brain or around it. Although this is a life-threatening problem, however, with advanced technology, it can be treated successfully. There are no specific causes discovered by specialists but genetic mutations and family history cause it. The symptoms can be really common like headache and nausea but can also be specific like difficulty in coordination, reflexes, speech, and many more. The timely diagnosis and treatment can give a new life to the child and reduces the chance of development of fresh tumor cells in the future.

Pediatric Brain Tumor - Know In Detail About It!

Acoustic neuroma is a benign tumor that occurs in the primary nerve between the brain and the ear. The tumor progresses very slowly and can influence your balance and hearing. In certain cases, if the tumor becomes very large, then it may also impair vital functions of the body.
Symptoms-
The symptoms of acoustic neuroma tend to develop when the tumor starts to press on the nerve and its adjoining branches. The symptoms of this disorder are  
You may experience hearing loss on one side which might worsen gradually.
You may have problems in balancing yourself.
A continuous ringing sound in the ears.
Persistent dizziness.
If the tumor is large and presses on the nearby nerves, then you may experience numbness of the facial muscles.
In some cases, it may impair the vital functions of the body.
This disorder is caused by a malfunctioning gene. There is no documented reason as to why the gene malfunctions.
The treatment options for this disorder are  
Constant Monitoring: These tumors tend to grow very slowly but might spurt in some cases. In order to prevent damage to your body, they need to be monitored on a regular basis. Imaging tests are recommended on a periodic basis to determine the growth of the tumor.
Radiosurgery: Stereotactic radiosurgery is done to treat acoustic neuroma that is small in size. In this surgery, radiation is directed at the tumor without creating any incision. It is done to limit the growth of the tumor and preserve your hearing.
Surgery: The tumor can be removed by using surgical procedures. It involves administering general anesthesia, followed by removing the tumor through an incision on the skull or the inner ear. Surgery is used to remove the tumor and preserve your hearing abilities. 

Acoustic Neuroma - Everything You Need to Know

Polio is a virus that has the potential to infect any parts of the body including, but not limited to nerves and muscles. Primarily there are 3 types of polio namely, non-paralytic, spinal paralytic and bulbar. This disease shows minimal to no symptoms in more than 90 percent of the cases. 5 percent of the cases can show symptoms such as nausea, diarrhea, vomiting, sore throat and abdominal pain. Polio is a communicable disease and can cause massive damage if a proper dosage is not taken. It can spread through air, physical contact with an infected person, coughs etc.

Polio can cause paralysis: Polio has a far-reaching permanent effect on the body. It can cause paralysis on any of the limbs leading to permanent disability. This severely alters a child s life. The far-reaching consequences of the virus can only be negated through vaccination.
Weak muscle: Polio can result in weak muscles, respiratory problems and loss of reflex. If the breathing muscle collapses, it can result in the death of a person. Any of the above-mentioned symptoms can lead to weak body development altering the fate of a child.
It can spread fast and quick: Polio spreads very fast through the air, physical contact, saliva and water. It not only affects a single life but put millions at risk of the disease. A 1916 outbreak of the disease killed 6000 people in the United States and left several thousands of people disabled.
It reduces the risk of infection: 3 dosages Polio vaccination under the age of 6 can save a baby from getting polio in future. The body successfully creates polio antibodies from the vaccines and gets enough ammunition to fight it if the virus attacks it in future.
Social responsibility: Massive amount of awareness campaigns have been run by countries all over the world to permanently eradicate polio from the face of the earth. As per the latest reports, only 3 countries are reported to have babies affected with polio; Afghanistan, Pakistan and Congo. It is, therefore, a social responsibility to take part in the mission of removing polio from the face of the earth once and for all.
Save future generation: Although polio is not known to be a disease which passes through heredity, there still lies a chance for the future generation to get this disease. In order to negate that from happening, it makes sense to get the vaccines on time.
Give your kid a head start: Every kid deserves to have an equal amount of privileges like others. One small mistake on part of the parents can heavily cost a child s future. In order to make sure your kids grow up with any apprehension of polio, it is very important to treat them with polio vaccines.

Polio Vaccination - Why Is It so Important?

Trigeminal neuralgia is specified by the condition of a chronic pain that influences the trigeminal nerve. This nerve transfers sensation from one s face to his/her brain. If a person is suffering from trigeminal neuralgia, then a gentle stimulation of face (sourced from brushing teeth or applying makeup) might generate a fright of agonizing pain. The affected person might experience short and mild attacks initially. However, the trigeminal neuralgia might progress and generate more-frequently and longer attack of severely critical pain. Women get affected by this situation more than men get and it is more prominently occur in individuals older than 50 years.

Trigeminal neuralgia does not mandatorily mean that you need to experience a lifelong pain. Various types of treatment alternatives are available and so doctors can usually handle the particular condition effectively by taking help of injections, medications or surgery. Various types of triggers might cause the pain regarding trigeminal neuralgia, such as eating, drinking, shaving, brushing teeth, touching face, smiling, washing face etc.

Symptoms

The symptoms of trigeminal neuralgia might comprise of one or more patterns and some of these are described below:

Sequences of serious, jolting or shooting pain that might generate as an electric shock
Spontaneous pain attacks or attacks stimulated by different activities like face touching, speaking, chewing, or brushing teeth. Pain attacks last from a few moments to some minutes.
It is not a comprehensive list because Trigeminal neuralgia hosts various other symptoms as well. If a person feels facial pain, specifically recurring or prolonged pain or if the person does not get relief through the utilization over-the-counter pain relievers, then that person must consult a doctor.
How does Radiofrequency Ablation treat Trigeminal Neuralgia?
Trigeminal Neuralgia is a chronic and painful condition that involves the trigeminal nerve. There are two separate trigeminal nerves on both sides of the face, which carry the sensations like pain from the face to the body. Each nerve has three branches- forehand, midface and chin and trigeminal neuralgia can cause intense pain in any of these areas.

Causes-

This occurs when the trigeminal nerve functioning is disrupted. When the blood vessel/artery and the trigeminal nerve at the base of your brain come in contact, it puts pressure on the nerves and causes pain.
It also occurs as a result of ageing or multiple sclerosis
A disorder that damages the myelin sheath protecting the nerves can trigger pain
Sometimes pain occurs from tumors, which compresses the trigeminal nerves
Surgical strokes, facial trauma or strokes can also be the root cause of excruciating pain
Triggers-

Shaving
Touching your face
Eating and drinking
Putting on makeup
Brushing
Washing your face
Symptoms-
The pain can be mild and for a shorter duration or it can happen frequently for longer durations. Some experience the pain in cycles where it can come and go for days or even for weeks. Gradually the intensity of the pain lessens.

Cure by Radio-frequency Ablation
The treatment of trigeminal neuralgia is often a challenging process in clinical practice. When medicines do not prove as effective, surgery is the desired option.

Procedure-

After applying local anaesthesia, the Pain Specialist carefully inserts a needle through the corner of your mouth to reach the trigeminal nerve
The doctors then wake up the patient after stimulating the nerves and ask them to feel the stimulation at the same place where they undergo pain. This confirms their targeted location
Once you fall asleep again, the Pain Specialist uses radiofrequency heat to injure the nerve enough to create numbness and removes the pain
How Effective is Radio-frequency Ablation?
The pain is cured almost in 98% of the patients. 50% of patients report recurrence of pain after about two years. Hence the procedure can be repeated in the same patient if necessary.
