What is Glossectomy : Procedure & causes

A glossectomy is surgical removal of the tongue. The surgery may be:
  1. Partial- removal of a part of the tongue.
  2. Semi-one side of the tongue is removed.
  3. Total- removal of the entire tongue.
Causes :
This surgery is used to treat cancer of the tongue when other treatments have not been successful.
Diagnosis:
 
If the biopsy shows that cancer is present, a complete physical examination of the patient’s head and neck is performed before surgery. The patient will meet with a treatment team before getting admitted to the hospital so they can answer questions and explain the treatment plan.
Surgical Procedure :
Glossectomies are always performed under general anesthesia. A partial glossectomy is a relatively simple procedure. If the hole left by the removal of the tumor is small, it is commonly repaired by stitching the tongue immediately or by using a small skin graft. If the glossectomy is wider, care is taken to repair the tongue so as to keep its mobility. A mutual approach is to use a skin piece taken from the wrist along with the blood vessels that supply it. This type of graft is called a radial forearm free flap. The flap is inserted into the hole in the tongue. This procedure needs a highly skilled surgeon who is able to connect very small arteries. The complete removal of the tongue called a total glossectomy is hardly performed.
Possible Complications:
Complications associated with this surgery includes,
  1. Bleeding from the tongue
  2. Difficulty in swallowing.
  3. Tongue swelling
  4. Infection
Average Recovery Period: Average recovery period of glossectomy -1 to 4 weeks

Schizophrenia: causes, symptoms & treatments

Schizophrenia: Meaning and definition

Schizophrenia most commonly strikes between the ages of 16 and 30, and males tend to show symptoms at a slightly younger age than females. In many cases, the disorder develops so slowly that the individual does not know that they have had it for many years. However, in other cases, it can strike suddenly and develop quickly.

Schizophrenia affects approximately 1 percent of all adults, globally. Experts say schizophrenia is probably many illnesses masquerading as one.

Some research suggests that schizophrenia may be the result of faulty neuronal development in the brain of the fetus, which later in life emerges as a full-blown illness.

Individuals with schizophrenia may hear voices that are not there. Some may be convinced that others are reading their minds, controlling how they think, or plotting against them. This can distress patients severely and persistently, making them withdrawn and, at times, frantic.

Symptoms of schizophrenia

A sizable proportion of people with schizophrenia have to rely on others because they are unable to hold a job or care for themselves. Many may also resist treatment, arguing that there is nothing wrong with them.

Some patients may present clear symptoms, but on other occasions, they may seem fine until they start explaining what they are truly thinking. The effects of schizophrenia reach far beyond the patient – families, friends, and society are affected too.

Symptoms and signs of schizophrenia will vary, depending on the individual.

The symptoms are classified into four categories:

  • Positive symptoms – also known as psychotic symptoms. For example, delusions and hallucinations.
  • Negative symptoms – these refer to elements that are taken away from the individual. For example, absence of facial expressions or lack of motivation.
  • Cognitive symptoms – these affect the person’s thought processes. They may be positive or negative symptoms, for example, poor concentration is a negative symptom.
  • Emotional symptoms – these are usually negative symptoms, such as blunted emotions.

Below is a list of the major symptoms:

  • Delusions – the patient displays false beliefs, which can take many forms, such as delusions of persecution, or delusions of grandeur. They may feel others are attempting to control them remotely. Or, they may think they have extraordinary powers and abilities.
  • Hallucinations – hearing voices is much more common than seeing, feeling, tasting, or smelling things which are not there, however, people with schizophrenia may experience a wide range of hallucinations.
  • Thought disorder – the person may jump from one subject to another for no logical reason. The speaker may be hard to follow or erratic.

Other symptoms may include:

  • Lack of motivation (avolition) – the patient loses their drive. Everyday actions, such as washing and cooking, are neglected.
  • Poor expression of emotions – responses to happy or sad occasions may be lacking, or inappropriate.
  • Social withdrawal – when a patient with schizophrenia withdraws socially, it is often because they believe somebody is going to harm them.
  • Unawareness of illness – as the hallucinations and delusions seem so real for patients, many of them may not believe they are ill. They may refuse to take medication for fear of side effects, or for fear that the medication may be poison, for example.
  • Cognitive difficulties – the patient’s ability to concentrate, recall things, plan ahead, and to organize their life are affected. Communication becomes more difficult.

What are the causes schizophrenia?

Experts believe several factors are generally involved in contributing to the onset of schizophrenia.

Evidence suggests that genetic and environmental factors act together to bring about schizophrenia. The condition has an inherited element, but environmental triggers also significantly influence it.

Below is a list of the factors that are thought to contribute towards the onset of schizophrenia:

Genetic inheritance

If there is no history of schizophrenia in a family, the chances of developing it are less than 1 percent. However, that risk rises to 10 percent if a parent was diagnosed.

Chemical imbalance in the brain

Experts believe that an imbalance of dopamine, a neurotransmitter, is involved in the onset of schizophrenia. Other neurotransmitters, such as serotonin, may also be involved.

Family relationships

There is no evidence to prove or even indicate that family relationships might cause schizophrenia, however, some patients with the illness believe family tension triggers relapses.

Environmental factors

Although there is no definite proof, many suspect trauma before birth and viral infections may contribute to the development of the disease.

Stressful experiences often precede the emergence of schizophrenia. Before any acute symptoms are apparent, people with schizophrenia habitually become bad-tempered, anxious, and unfocused. This can trigger relationship problems, divorce, and unemployment.

These factors are often blamed for the onset of the disease, when really it was the other way round – the disease caused the crisis. Therefore, it is extremely difficult to know whether schizophrenia caused certain stresses or occurred as a result of them.

Drug induced schizophrenia

Marijuana and LSD are known to cause schizophrenia relapses. Additionally, for people with a predisposition to a psychotic illness such as schizophrenia, usage of cannabis may trigger the first episode.

Some researchers believe that certain prescription drugs, such as steroids and stimulants, can cause psychosis.

Schizophrenia diagnosis and tests

Before diagnosing schizophrenia, other conditions need to be ruled out first.

A schizophrenia diagnosis is reached by observing the actions of the patient. If the doctor suspects possible schizophrenia, they will need to know about the patient’s medical and psychiatric history.

Certain tests will be ordered to rule out other illnesses and conditions that may trigger schizophrenia-like symptoms, such as:

  • Blood tests – in cases where drug use may be a factor a blood test may be ordered. Blood tests are also done to exclude physical causes of illness.
  • Imaging studies – to rule out tumors and problems in the structure of the brain.
  • Psychological evaluation – a specialist will assess the patient’s mental state by asking about thoughts, moods, hallucinations, suicidal traits, violent tendencies, or potential for violence, as well as observing their demeanor and appearance.

Schizophrenia diagnosis criteria

Patients must meet the criteria outlined in the DSM (Diagnostic and Statistical Manual of Mental Disorders). This is an American Psychiatric Association manual used by healthcare professionals to diagnose mental illnesses and conditions.

The doctor needs to exclude other possible mental health disorders, such as bipolar disorder or schizoaffective disorder.

It is also important to establish that the signs and symptoms have not been caused by, for example, a prescribed medication or substance abuse.

The patient must:

  • Have at least two of the following typical symptoms:
    • delusions
    • disorganized or catatonic behavior
    • disorganized speech
    • hallucinations
    • negative symptoms that are present for much of the time during the last 4 weeks
  • Experience considerable impairment in the ability to attend school, carry out their work duties, or carry out everyday tasks.
  • Have symptoms that persist for 6 months or more.

Treatments :

With proper treatment, patients can lead productive lives. Treatment can help relieve many of the symptoms of schizophrenia. However, the majority of patients with the disorder have to cope with the symptoms for life.

Psychiatrists say the most effective treatment for schizophrenia patients is usually a combination of:

  • medication
  • psychological counseling
  • self-help resources

Anti-psychosis drugs have transformed schizophrenia treatment. Thanks to them, the majority of patients are able to live in the community, rather than stay in a hospital.

The most common schizophrenia medications are:

  • Risperidone (Risperdal) – less sedating than other atypical antipsychotics. Weight gain and diabetes are possible side effects, but are less likely to happen, compared with Clozapine or Olanzapine.
  • Olanzapine (Zyprexa) – may also improve negative symptoms. However, the risks of serious weight gain and the development of diabetes are significant.
  • Quetiapine (Seroquel) – risk of weight gain and diabetes, however, the risk is lower than Clozapine or Olanzapine.
  • Ziprasidone (Geodon) – the risk of weight gain and diabetes is lower than other atypical antipsychotics. However, it might contribute to cardiac arrhythmia.
  • Clozapine (Clozaril) – effective for patients who have been resistant to treatment. It is known to lower suicidal behaviors in patients with schizophrenia. The risk of weight gain and diabetes is significant.
  • Haloperidol – an antipsychotic used to treat schizophrenia. It has a long-lasting effect (weeks).

The primary schizophrenia treatment is medication. Sadly, compliance (following the medication regimen) is a major problem. People with schizophrenia often come off their medication for long periods during their lives, at huge personal costs to themselves and often to those around them.

The patient must continue taking medication even when symptoms are gone. Otherwise they will come back.

The first time a person experiences schizophrenia symptoms, it can be very unpleasant. They may take a long time to recover, and that recovery can be a lonely experience. It is crucial that a person living with schizophrenia receives the full support of their family, friends, and community services when onset appears for the first time.

Carcinoid Syndrome: Causes, Symptoms & Treatments

What Is Carcinoid Syndrome?

Carcinoid syndrome is a group of symptoms you might get if you already have a type of cancer called carcinoid tumors. It starts when the tumors release chemicals into your bloodstream. The symptoms can be similar to other illnesses, like asthma, irritable bowel syndrome, and menopause. You may have episodes when your skin suddenly gets red and warm, you have trouble breathing, or you have a rapid heartbeat, for example.

Carcinoid tumors usually grow in your stomach and intestines, but you can also get them in your lungs, pancreas, or rarely, testicles or ovaries. If you have carcinoid syndrome, it usually means that your cancer has spread to another area, most often your lungs or liver.

Although there’s no cure for carcinoid tumors, treatments can help you live longer and better. You can also take steps to relieve the symptoms of carcinoid syndrome and feel more comfortable.

You have control over decisions about your treatment and your life. Find people you can talk to about your plans, your fears, and your feelings. Ask your doctor about support groups, where you can meet people who understand what you’re going through.

Causes :

You get carcinoid syndrome when your carcinoid tumors release hormones and proteins into your body. Where your tumors are will determine what substances they make.

When the tumors are in your digestive tract, a common place for them to grow, extra hormones usually go into a blood vessel that takes them to your liver, which makes them inactive. If your tumors have spread there, your liver won’t be able to do its job of breaking down those hormones. Instead, they may start moving through your bloodstream to affect different parts of your body and cause symptoms.

You could get carcinoid syndrome from tumors in the lungs, testes, or ovaries. In those cases, the extra hormones go directly into your bloodstream.

Symptoms:

People with carcinoid syndrome may have:

  • Skin that turns a pink, red, or purple color
  • Small, widened blood vessels on their face
  • Diarrhea
  • Shortness of breath or wheezing
  • Rapid heart rate
  • Sudden drops in blood pressure

Carcinoid syndrome can also cause complications. It’s rare, but you could get heart disease. Your heart valves may get thick and leak. Medicine can help, and in some cases you might need surgery.

Carcinoid crisis isn’t very common, but you might have a severe episode of blushing, breathing trouble, and confusion. This is an emergency that could be life-threatening, so get medical help right away.

Treatment :

To treat carcinoid syndrome, your doctors will need to treat your tumors. You could need just one or a combination of treatments. Medication may help with your related symptoms.

 

Surgery. Doctors may take out an entire organ that has tumors, such as your appendix, or remove only part of an affected area, such as a section of your bowel.

Depending on where the tumor is, surgeons may also use an electric current to burn it off or do cryosurgery to freeze it. Another option could be radiofrequency ablation. Your surgeon will use an instrument that sends electrical energy into the tumor to kill cancer cells.

Chemotherapy. Strong medicines can often kill your cancer cells or slow their growth. Some of these drugs are taken by mouth and others are injected into a vein.

Radiation. This treatment can destroy cancer cells or keep them from multiplying. The radiation can come from a machine outside your body, or your doctor may place a small amount of radioactive material inside your body, in or near the tumor.

Biologic drugs. This type of treatment, which is also called immunotherapy, strengthens your body’s defense system. Doctors inject drugs into your body that help your immune system kill cancer cells.

Drug therapy. Injected drugs such as lanreotide, octreotide, and pasireotide can help with skin flushing. They may also have a small effect on stopping tumor growth. Octreotide can ease diarrhea, too.

 

Intracerebral Hemorrhage: Causes, Symptoms & Treatments

What Is Intracerebral Hemorrhage?

Intracerebral hemorrhage (ICH) is when blood suddenly bursts into brain tissue, causing damage to the brain.

Symptoms usually appear suddenly during ICH. They include headache, weakness, confusion, and paralysis, particularly on one side of the body. The buildup of blood puts pressure on the brain and interferes with its oxygen supply. This can quickly cause brain and nerve damage.

This is a medical emergency requiring immediate treatment. ICH is not as common as ischemic stroke (when a blood vessel is blocked by a clot), but it’s more serious.

Treatment generally involves surgery to relieve the pressure from the accumulation of blood and to repair damaged blood vessels. Long-term treatment depends on the hemorrhage location and the amount of damage. Treatment may include physical, speech, and occupational therapy. Most people have some level of permanent disability

What Are the Causes of Intracerebral Hemorrhage?

High blood pressure is the most common cause of intracerebral hemorrhage. In younger people, another common cause is abnormally formed blood vessels in the brain. Other causes include:

  • head injury or trauma
  • ruptured cerebral aneurysm (weak spot in a blood vessel that bursts)
  • arteriovenous malformation (a grouping of malformed blood vessels in the brain that disrupts normal blood flow)
  • use of blood thinners
  • bleeding tumors
  • cocaine use (can cause severe hypertension and lead to hemorrhage)
  • bleeding disorders (e.g., hemophilia, sickle cell anemia)

Anyone can have an intracerebral hemorrhage, but your risk increases with age.

What Are the Symptoms of Intracerebral Hemorrhage?

Symptoms of ICH include:

  • sudden weakness, tingling, or paralysis in the face, arm, or leg, especially if it occurs on only one side of the body
  • sudden onset of severe headache
  • trouble swallowing
  • trouble with vision in one or both eyes
  • loss of balance and coordination, dizziness
  • trouble with language skills (reading, writing, speaking, understanding)
  • nausea, vomiting
  • apathy, sleepiness, lethargy, loss of consciousness
  • confusion, delirium

What Are the Complications of Intracerebral Hemorrhage?

Depending on the location of the hemorrhage and how long your brain was without oxygen, complications may include:

  • impaired language skills
  • fatigue
  • problems with swallowing
  • vision loss
  • difficulty with sensations or movements on one side of the body
  • pneumonia
  • cognitive dysfunction (memory loss, difficulty reasoning), confusion
  • swelling on the brain
  • seizures
  • depression, emotional problems
  • fever

How Is Intracerebral Hemorrhage Treated?

Treatment within the first three hours of the onset of symptoms generally results in a better outcome.

Surgery can relieve pressure on the brain and repair torn arteries. Certain medications can help manage symptoms, such as painkillers to ease severe headaches. Antianxiety drugs may be necessary to control blood pressure. If your doctor determines that you’re at risk for seizures, antiepileptic drugs may be necessary.

Long-term treatment will be needed to overcome symptoms caused by damage to the brain. Depending on your symptoms, treatment may include physical and speech therapy to help restore muscle function or improve communication. Occupational therapy may help a person regain certain skills and independence by practicing and modifying everyday activities.

How Can I Prevent Intracerebral Hemorrhage?

You can decrease your chances of ICH by:

  • not smoking
  • treating heart disease
  • treating high blood pressure
  • keeping diabetes under control
  • maintaining a healthy lifestyle

 

 

Vestibular Hypofunction : Symptoms & Treatments

What is Vestibular Hypofunction

Symptoms are characterized by dizziness, vertigo, instability and balance problems. History of recent viral infection, upper respiratory infection or ear infection is very common. It may also be the result of head trauma, temporal bone fracture, acoustic neuroma, antibiotic use (gentimiacin) or unknown etiologies.

In the beginning, you may experience constant symptoms and require a few days of bed rest. But over time, symptoms may only be aggravated by head movement, visually stimulating environments/activities, etc. This is because of impaired gaze stabilization (VOR). Walking in the dark and on uneven surfaces may also be difficult and unsafe. This is because you are unable to relay on your vestibular system for balance when other systems are compromised (vision and feet). It is important to take caution in these situations. Always turn on lights, avoid over stimulating tasks and surfaces you cannot safely negotiate.

Treatment for Vestibular Hypofunction :

Inner ear health is dependent on movement. Just like you would use a dumbbell to strengthen your bicep muscle, you use head and eye movement to strengthen your vestibular system.

Of course, in the beginning of treatment you may be very motion sensitive. It is important to do prescribed exercises as tolerated and slowly increase the time, speed and amount of exercise. More is not necessarily better!

Exercise goals are to promote inner ear adaptation and to challenge the balance component of the vestibular system.

Exercise and its progressions will be tailored to your individual symptoms and needs.

Varicose Veins: Causes, Symptoms & Treatments

What are varicose veins?

Varicose veins, also known as varicoses or varicosities, occur when your veins become enlarged, dilated, and overfilled with blood. Varicose veins typically appear swollen and raised, and have a bluish-purple or red color. They are often painful.

The condition is very common, especially in women. Around 25 percent of all adults have varicose veins. In most cases, varicose veins appear on the lower legs.

Causes of varicose veins

Varicose veins occur when veins aren’t functioning properly. Veins have one-way valves that prevent blood from flowing backward. When these valves fail, blood begins to collect in the veins rather than continuing toward your heart. The veins then enlarge. Varicose veins often affect the legs. The veins there are the farthest from your heart, and gravity makes it harder for the blood to flow upward.

Some potential causes for varicose veins include:

  • pregnancy
  • menopause
  • age over 50
  • standing for long periods of time
  • obesity
  • family history of varicose veins
 Symptoms of varicose veins:

The primary symptoms of varicose veins are highly visible, misshapen veins, usually on your legs. You may also have pain, swelling, heaviness, and achiness over or around the enlarged veins.

In some cases, you can develop swelling and discoloration. In severe cases, the veins can bleed significantly, and ulcers can form.

Treating and preventing varicose veins

In general, doctors are conservative when treating varicose veins. You’ll probably be advised to make changes to your lifestyle, instead of trying more aggressive treatments.

Lifestyle changes

The following changes may help prevent varicose veins from forming or becoming worse:

  • Avoid standing for extended periods of time.
  • Lose weight or maintain a healthy weight.
  • Exercise to improve your circulation.
  • Use compression socks or stockings.

If you already have varicose veins, you should take these steps to prevent new varicose veins. You should also elevate your legs whenever you’re resting or sleeping.

Compression

Your doctor may advise you to wear special compression socks or stockings. These place enough pressure on your legs so that blood can flow more easily to your heart. They also decrease swelling.

The level of compression varies, but most types of compression stockings are available in drugstores or medical supply stores.

Surgery

If lifestyle changes aren’t working, or if your varicose veins are causing a lot of pain or damaging your overall health, your doctor might try an invasive procedure.

Vein ligation and stripping is a surgical treatment that requires anesthesia. During the procedure, your surgeon makes cuts in your skin, cuts the varicose vein, and removes it through the incisions. Although updated variations of vein-stripping surgeries have been developed, they are less commonly performed because newer, less invasive options are available.

Other treatment options

Currently, a wide variety of minimally invasive treatment options for varicose veins are available. These include:

  • sclerotherapy, using a liquid or foam chemical injection to block off a larger vein
  • microsclerotherapy, using a liquid chemical injection to block off smaller veins
  • laser surgery, using light energy to block off a vein
  • endovenous ablation therapy, using heat and radiofrequency waves to block off a vein
  • endoscopic vein surgery, using a small lighted scope inserted through a small incision to block off a vein

You should always talk to your doctor about your treatment options and the risks before choosing a method. The method recommended can depend on your symptoms, size, and location of the varicose vein.

 

 

Variation of Hemoglobin levels: Causes, Symptoms & treatments

What does a low hemoglobin level mean?

A low hemoglobin level is referred to as anemia or low red blood count. A lower than normal number of red blood cells is referred to as anemia and hemoglobin levels reflect this number. There are many reasons (causes) for anemia.

Some of the more common causes of anemia are:

  • loss of blood (traumatic injury, surgery, bleeding, colon cancer, or stomach ulcer),
  • nutritional deficiency (iron, vitamin B12, folate),
  • bone marrow problems (replacement of bone marrow by cancer),
  • suppression by red blood cell synthesis bychemotherapy drugs,
  • kidney failure, and
  • abnormal hemoglobin structure (sickle cell anemia or thalassemia).

What does a high hemoglobin level mean?

Higher than normal hemoglobin levels can be seen in people living at high altitudes and in people who smoke. Dehydration produces a falsely high hemoglobin measurement that disappears when proper fluid balance is restored.

Some other infrequent causes are high hemoglobin levels are:

  • advanced lung disease (for example, emphysema);
  • certain tumors;
  • a disorder of the bone marrow known as polycythemia rubra vera, and;
  • abuse of the drug erythropoietin (Epogen) by athletes for blood doping purposes (increasing the amount of oxygen available to the body by chemically raising the production of red blood cells).

What is sickle cell disease?

Sickle cell disease is a genetic condition in which the quality of hemoglobin is defective. This condition can cause abnormal hemoglobin that can result in abnormally-shaped (sickled) red blood cells (see illustration). These abnormal red blood cells cannot easily pass through small blood vessels leading to inadequate oxygen for the tissues of the body.

Sickle cells also have a shorter life span than normal red blood cells (10 to 20 days compared to 120 days). This rapid turnover may result in inadequate time to replace the red blood cells and may result in anemia.

In sickle cell anemia, one defective hemoglobin gene is inherited from each parent. If only one gene is inherited from one parent, then the condition is milder and referred to as sickle cell trait.

Symptoms of sickle cell anemia vary depending on its severity. Patients with sickle cell trait may experience mild, if any, symptoms at all. In sickle cell disease, symptoms are more significant, especially in episodes of acute crisis. These symptoms can include:

  • generalized body aches and pain,
  • chest pain,
  • bone pain,
  • shortness of breath,
  • ulceration of skin,
  • fatigue,
  • strokes,
  • blindness, and
  • delayed growth and puberty.

What is thalassemia?

Thalassemia is a group of hereditary conditions with quantitative hemoglobin deficiency. The body’s failure to make globulin molecules will lead to a compensatory mechanism to make other less compatible globulin molecules. The different types of thalassemia are defined based on what type of globulin molecule is deficient. The severity of these conditions depends on the type of deficient globulin chain, the number of deficient globulins, and the severity of the underproduction. Mild disease may only present as mild anemia whereas severe deficiency may not be compatible with life.

How can a person increase his or her hemoglobin level?

There are a number of ways to increase hemoglobin levels. In general, low hemoglobin levels that need to be increased are caused by three circumstances: decreased red blood cell production (for example, altered bone marrow hemoglobin production, iron deficiency), increased red blood cell destruction (for example, liver disease), and by blood loss (for example, trauma from a gunshot or knife wound). Addressing these underlying causes of low hemoglobin levels initially determines what method to use to increase hemoglobin levels.

Methods to increase hemoglobin levels are varied and their use depends on the underlying problems. Some of the ways to increase hemoglobin include:

  • transfusing red blood cells
  • receiving erythropoietin (a hormone used to stimulate red blood cell production in individuals with decreased red blood cell production or increased red cell destruction)
  • taking iron supplements
  • increasing the intake of iron-rich foods (eggs, spinach, artichokes, beans, lean meats, and seafood) and foods rich in cofactors (such as vitamin B6, folic acid, vitamin B12, and vitamin C) important for maintaining normal hemoglobin levels. Such foods include fish, vegetables, nuts, cereals, peas, and citrus fruits.

Individuals should not take iron supplements or other treatments for low hemoglobin levels without first discussing such treatments with their physician as side effects from these treatments and/or excess iron intake may cause additional problems. Also, iron supplements should be kept away from children as iron poisoning in young children can be fatal
