Vocal cord paralysis, also known as vocal fold paralysis is a medical condition characterized by the inability of one or both vocal cords to move or function properly. The vocal cords are located in the larynx or the voice box and play a crucial role in producing sound and enabling speech. In vocal cord paralysis, one or both of the vocal cords may become partially or completely paralyzed (Toutounchi, S.J.S., Eydi, M., Golzari, S.E., Ghaffari, M.R. and Parvizian, N., 2014. Vocal cord paralysis and its etiologies: a prospective study. Journal of cardiovascular and thoracic research, 6(1), p.47). This can result in a variety of symptoms, some of which may include including:

Symptoms of Vocal Cord Paralysis

Hoarseness or raspy voice: The voice may sound breathy, weak or strained due to the impaired movement of the affected vocal cord.

Voice fatigue: Speaking for extended periods can be tiring and may lead to a loss of voice or increased effort to produce sound.

Difficulty swallowing: The paralyzed vocal cord or cords may interfere with the normal closure of the larynx during swallowing, leading to swallowing difficulties or choking sensations.

Breathing difficulties: If the vocal cord fails to close properly during inhalation, it can cause breathing problems, especially during exercise or sleep.

Aspiration: If the vocal cord cannot close adequately during swallowing, food, liquids or saliva may enter the airway, leading to coughing, choking or recurrent respiratory infections.

Management of Vocal Cord Paralysis

Management and treatment of vocal cord paralysis usually depend on the underlying cause as well as the severity of the condition. In some cases, the paralysis may resolve on its own without any intervention. However, if the symptoms persist or cause significant functional impairment, treatment options may include voice therapy to improve vocal cord function, surgical procedures to reposition or reshape the vocal cords, or injections into the vocal cords to improve their movement. These may further be discussed as the following:

Voice therapy: Voice therapy can be beneficial for individuals with vocal cord paralysis. A speech-language pathologist can teach techniques to improve vocal cord function, breath control and voice projection (Walton, C., Carding, P. and Flanagan, K., 2018. Perspectives on voice treatment for unilateral vocal fold paralysis. Current Opinion in Otolaryngology & Head and Neck Surgery, 26(3), pp.157-161). These exercises help maximize vocal efficiency and reduce strain on the vocal cords.

Surgical interventions: Surgery may be recommended in cases where vocal cord paralysis significantly affects voice quality or breathing. The type of surgery will depend on the specific needs and conditions of the individual. Some surgical options may comprise of the following:

Vocal cord injection: This procedure involves injecting a filler substance, such as collagen or hyaluronic acid into the affected vocal cord to improve its movement and voice quality.

Vocal cord medialization: In this procedure, a small implant or suture is placed to reposition the paralyzed vocal cord, allowing it to meet the unaffected vocal cord more effectively during speech and swallowing.

Thyroplasty: Thyroplasty involves reshaping the thyroid cartilage to adjust the position and tension of the vocal cords, improving voice quality and control.

Treatment of the underlying cause: If vocal cord paralysis is caused by an underlying medical condition or injury, treating that condition may help resolve or improve the paralysis. This may include medication, therapy or addressing any structural issues or nerve damage.

Breathing and swallowing management: For individuals with breathing difficulties or swallowing problems due to vocal cord paralysis, strategies such as postural adjustments, diet modifications and swallowing therapy may be recommended to improve safety and quality of life.

Supportive measures

In addition to specific treatments, certain supportive measures can help manage vocal cord paralysis. These may include:

Vocal rest: Limiting voice use and avoiding excessive speaking or shouting can help prevent further strain on the vocal cords (Ryu, C.H., Kwon, T.K., Kim, H., Kim, H.S., Park, I.S., Woo, J.H., Lee, S.H., Lee, S.W., Lim, J.Y., Kim, S.T. and Jin, S.M., 2020. Guidelines for the management of unilateral vocal fold paralysis from the Korean society of laryngology, phoniatrics and logopedics. Clinical and experimental otorhinolaryngology, 13(4), pp.340-360).

Hydration: Staying hydrated by drinking enough fluids can help keep the vocal cords lubricated and reduce vocal fatigue.

Thyroid function is measured by several hormones, including thyroid-stimulating hormone (TSH), free thyroxine (FT4) and triiodothyronine (T3). Normal thyroid levels can vary slightly depending on the laboratory reference ranges and individual factors. However, the generally accepted normal thyroid level in female may be identified as the following:

TSH (Thyroid-Stimulating Hormone): The normal range for TSH is typically between 0.4 and 4.0 mIU/L (milli-international units per liter). However, some experts suggest that a narrower range of 0.4 to 2.5 mIU/L may be more optimal.

FT4 (Free Thyroxine): The normal range for FT4 is generally between 0.8 and 1.8 ng/dL (nanograms per deciliter).

T3 (Triiodothyronine): The normal range for T3 is usually between 80 and 200 ng/dL.

It's important to note that these ranges are general guidelines, and individual factors and specific circumstances may require a more personalized approach (Alam Khan, V., Khan, M.A. and Akhtar, S., 2002. Thyroid disorders, etiology and prevalence. J Med Sci, 2(2), pp.89-94). If a patient has concerns about his thyroid levels, it is always recommended to consult with a healthcare professional who can evaluate his specific situation and provide appropriate guidance.

Thyroid issues have become widely common in both males and females. Thyroid symptoms for male and female patients may often vary although there are also many similarities. Read along to know the potential differences in thyroid symptoms that may occur in males:

Fatigue and weakness: Both males and females with thyroid issues may experience fatigue and weakness (Sawicka-Gutaj, N., Ziółkowska, P., Wojciechowska, K., Shawkat, S., Czarnywojtek, A., Warchoł, W., Sowiński, J., Szczepanek-Parulska, E. and Ruchała, M., 2021. Eye symptoms in patients with benign thyroid diseases. Scientific Reports, 11(1), p.18706). However, males may be more likely to attribute these symptoms to other factors, such as stress or aging, rather than considering thyroid dysfunction.

Muscle mass and weight changes: Thyroid disorders can affect body composition and weight. In males, an underactive thyroid or hypothyroidism may lead to a decrease in muscle mass, weight gain and difficulty losing weight. On the other hand, an overactive thyroid or hyperthyroidism can cause weight loss and a decrease in muscle mass.

Sexual and reproductive symptoms: Males with thyroid dysfunction may experience changes in libido, erectile dysfunction or decreased fertility. These thyroid symptoms for male patients can be related to hormonal imbalances caused by thyroid disorders.

Emotional changes: While both genders can experience emotional changes due to thyroid problems, males may be more likely to exhibit irritability or anger rather than depression or anxiety commonly seen in females.

Cardiovascular symptoms: Hyperthyroidism in males may be associated with different kinds of cardiovascular symptoms like an increased heart rate, palpitations and high blood pressure.

It is important to know that these differences are not definitive and thyroid symptoms can vary widely among individuals, regardless of gender. Additionally, many symptoms of thyroid disorders can overlap between males and females. If a person suspects having a thyroid issue, it is essential to consult a healthcare professional for proper evaluation and diagnosis.

Management of thyroid symptoms for male and female patients

Managing thyroid problems typically involves a combination of medical treatments, lifestyle modifications and regular monitoring. Some general strategies for managing thyroid problems may include the following:

Medical treatment: Thyroid disorders such as hypothyroidism or hyperthyroidism are often treated with medications. These medications aim to restore thyroid hormone levels to a balanced state. It is important to follow your healthcare professional's prescribed treatment plan, take medications as directed and attend regular check-ups.

Regular monitoring: Thyroid function should be regularly monitored through blood tests to assess hormone levels and adjust medication dosages as needed (Shaha, A.R., 2000. Controversies in the management of thyroid nodule. The laryngoscope, 110(2), pp.183-183). Follow-up appointments with your healthcare professional are crucial for ongoing management.

Healthy diet: A well-balanced diet that includes adequate amounts of iodine, selenium and other essential nutrients can support thyroid health. Consult with a registered dietitian or healthcare professional to develop a personalized diet plan that meets your specific needs.

Stress management: Stress can have an impact on thyroid function. It is beneficial to engage in stress-reducing activities such as exercise, meditation, deep breathing exercises or hobbies to help manage stress levels.

Regular exercise: Regular physical activity can help boost metabolism, maintain a healthy weight and improve overall well-being. Thyroid patients are often recommended to follow a combination of cardiovascular exercise, strength training and flexibility exercises. However, it is important to consult a healthcare professional before starting any exercise program.

Adequate sleep: Patients must prioritize getting enough restful sleep each night. They must strive to establish a consistent sleep routine, create a sleep-friendly environment and practice good sleep hygiene habits.

Avoid smoking and limit alcohol: Smoking can negatively affect thyroid function, so quitting smoking is always advisable (Knudsen, N., Bulow, I., Laurberg, P., Perrild, H., Ovesen, L. and Jorgensen, T., 2002. High occurrence of thyroid multinodularity and low occurrence of subclinical hypothyroidism among tobacco smokers in a large population study. Journal of Endocrinology, 175(3), pp.571-576). Additionally, excessive alcohol consumption can interfere with thyroid hormone production, so it is best to consume alcohol in moderation or avoid it altogether.        

Self-awareness and education: It is important for patients to learn about their specific thyroid condition and its management. They must stay informed about any new research, treatment options or lifestyle recommendations related to thyroid health.

Vocal cord paralysis is a condition where a person is not able to control muscle movements that control his voice. It usually happens due to disruptions in the nerve impulses to a person’s larynx. This leads to paralysis of the muscles present in the vocal cord. This condition makes it difficult for the patient to speak or even breathe. This is because the vocal cords have more roles than merely producing sound. They protect a person’s airways by preventing food objects from entering the windpipe thereby helping a person to prevent choking (Toutounchi, S.J.S., Eydi, M., Golzari, S.E., Ghaffari, M.R. and Parvizian, N., 2014. Vocal cord paralysis and its etiologies: a prospective study. Journal of cardiovascular and thoracic research, 6(1), p.47). Usually, in the case of vocal cord paralysis, one vocal cord is paralyzed. However, in a few severe cases, a person may also suffer from paralysis of both vocal cords. This is a serious condition that may lead to speech difficulties as well as problems in swallowing and breathing. For more information and insights on this condition, follow DocTube.

Symptoms of Vocal Cord Paralysis

The common signs and symptoms of vocal cord paralysis are diverse and may include the following:

Hoarseness

Noisy breathing

Loss of vocal pitch

Shortness of breath

Coughing or choking while drinking or swallowing food

Inability to speak loudly

A need to take frequent breaths while speaking

Ineffective coughing

Loss of the gag reflex

Frequent throat clearing

Whenever a person experiences unexplained voice hoarseness that does not go away even after 2-4 weeks or if there are unexplained voice changes and discomfort, it is crucial for him to make a prompt consultation with a healthcare provider.

Causes of Vocal Cord Paralysis

In the case of vocal cord paralysis, a person’s nerve impulses to his larynx are disrupted which causes paralysis of the muscle. It often becomes difficult for healthcare providers to determine the main cause of this vocal cord paralysis. However, some of the commonly known causes may often comprise the following:

Chest or neck injury: Often trauma to the chest or neck can injure nerves that serve the vocal cords or the larynx. 

Vocal cord injury during surgery: Surgery on or near the upper chest or neck may lead to some damage to the nerves that serve the larynx (Gupta, J., Varshney, S., Bist, S.S. and Bhagat, S., 2013. Clinico-etiolological study of vocal cord paralysis. Indian Journal of Otolaryngology and Head & Neck Surgery, 65, pp.16-19). Some of the common surgeries that involve a certain degree of risk of damage are surgeries to the parathyroid or thyroid glands, chest, neck and esophagus. 

Stroke: Strokes interrupt the flow of blood in the brain and this may damage the part of our brain that is responsible for sending messages to the larynx.

Tumors: Cancerous as well as non-cancerous tumors may grow in and around the nerves, muscles and cartilage that control the functioning of the larynx and this may lead to vocal cord paralysis in patients.

Infections: Some infections like herpes and Lyme disease may lead to inflammation and damage of the nerves in the voice box. It has also been found that COVID-19 infection may cause vocal cord paralysis in individuals. 

Neurological conditions: Vocal cord paralysis may also be caused by certain neurological conditions like Parkinson’s disease and multiple sclerosis. 

People who undergo surgery on their throat, upper chest or thyroid have a higher risk of damaging their vocal cord nerve. In some cases, the breathing tubes used during surgery or for helping a patient to breathe if he has severe respiratory trouble may damage his vocal cord nerves. On the other hand, as stated above, patients with certain neurological conditions like multiple sclerosis and Parkinson’s disease are more prone to suffer from weakness or paralysis of their vocal cords. 

Complications of Vocal Cord Paralysis

Breathing issues linked to vocal cord paralysis may be mild enough to be causing just a hoarse voice. However, in severe cases, they may also be life-threatening. As vocal cord paralysis prevents the opening of the airway from closing and opening completely, other complications may also be faced. These may include inhaling or choking on food or liquid. Aspiration can result in severe pneumonia and this condition needs immediate medical care. 

Treatment of Vocal Cord Paralysis

Surgery and voice therapy are the most common treatments done for vocal cord paralysis. In some patients, their voices will recover naturally during the first year following diagnosis and it is because of this reason that doctors may often delay surgery for a year. During this time, doctors usually refer patients to speech-language pathologists. Voice therapy is recommended for such patients. This involves exercises for strengthening the vocal cords and improving breath control while talking. These therapists may teach patients how to use their voices differently. For example, this may include opening the mouth wider when you speak or speaking slowly. On the other hand, different surgical procedures are also available and this usually depends on whether one or both the vocal cords are paralyzed. 

An atrial septal defect is a birth defect wherein there is a hole in the wall that divides the atria or the upper chambers of the heart. This hole may differ in size and in many cases may close on its own. However, in some cases, it may require surgery. An atrial septal defect is one of the common kinds of congenital heart defects or those defects that are present at birth. A baby’s heart develops during pregnancy and thus there are several openings in the wall that divides the upper chambers of the heart. These holes generally close during pregnancy or within a short span of time after birth. However, if one of these openings do not close, a hole is left and this is termed an atrial septal defect (Geva, T., Martins, J.D. and Wald, R.M., 2014. Atrial septal defects. The Lancet, 383(9932), pp.1921-1932). This hole increases the amount of blood flowing through the baby’s lungs and with time, it causes damage to the blood vessels in the lungs. On the other hand, damage to the blood vessels in the lungs can lead to complications as the child grows and enters adulthood and some of these problems may include high blood pressure and heart failure. In addition to these, other complications may include an increased risk of stroke and abnormal heartbeat.

Diagnosis of  an Atrial Septal Defect

An atrial septal defect can be diagnosed during pregnancy and may also be detected after the child is born. However, in several cases, it may be left undetected until the child reaches adulthood. During pregnancy, a woman may go for different kinds of screening tests or prenatal tests to diagnose birth defects as well as other conditions. An atrial septal defect can be seen by an ultrasound (Webb, G. and Gatzoulis, M.A., 2006. Atrial septal defects in the adult: recent progress and overview. Circulation, 114(15), pp.1645-1653). However, this is usually dependent on the location and the size of the hole. Whenever an atrial septal defect is suspected, specialists are required to confirm the diagnosis. On the other hand, genetic testing may also be helpful if the patients or any of their biological family members have congenital heart disease. An atrial septal defect is usually present at birth. However, many babies may not have any signs and symptoms. For the best insights on this condition, follow DocTube.  

Symptoms of  an Atrial Septal Defect

Some of the most common signs of untreated atrial septal defect may comprise the following:

Difficulty breathing

Frequent lung or respiratory infections

Tiring when feeding the baby

Shortness of breath while exercising or being active

Skipped heartbeat

Swelling of the stomach area, feet or legs

A whooshing sound or a heart murmur that is heard with a stethoscope. 

As stated above, in many cases, atrial septal defects are not diagnosed until a child reaches adulthood. One of the best and commonest ways this condition is diagnosed is by detecting murmurs when listening to the patient’s heart with a stethoscope. The healthcare professional usually requests some other tests to confirm the diagnosis if a murmur is heard or if other symptoms are present in the patient. Echocardiogram is the most common test which includes conducting an ultrasound of the heart. 

Treatment of an Atrial Septal Defect

Atrial septal defects may be closed through percutaneous or non-surgical repair or through surgical methods. The kind of treatment usually depends on diverse factors such as the size and the type of defect and how the condition is affecting the patient’s heart (Liava’a, M. and Kalfa, D., 2018. Surgical closure of atrial septal defects. Journal of thoracic disease, 10(Suppl 24), p.S2931). It also depends on other conditions that the patient may have like coronary artery disease, valve disease or pulmonary hypertension. Small atrial septal defects usually do not need any repair. On the other hand, larger atrial septal defects must be treated and repaired even if they are not causing any problems. This is important as this helps to prevent many different kinds of serious complications in the future. Repair becomes essential whenever a person exhibits any signs of lung or heart damage. Healthcare professionals recommend prompt treatment if the right side of the heart is larger than normal or if there is a significant amount of shunting or flow of blood through the ASD. 

Medications may be prescribed for treating some symptoms of atrial septal defect. However, it is important to note that there are no medications that can close this hole. In addition, if the person suffers from pulmonary hypertension, he must take relevant medications before the repair procedure is done. This is important as such medication helps to treat pulmonary hypertension while making the procedure safer for the patient. Closure of the hole is commonly recommended for adults who have many and severe symptoms. This closure may be done during open-heart surgery or cardiac catheterization. After such procedures are done, follow-up care depends on the patient’s age, the size of the defect and the presence of any other birth defects.

Prevention of an Atrial Septal Defect

It is important to note that there is no particular way to prevent this defect. They may develop when the fetus is still present in the uterus. However, proper prenatal care can have a substantial impact on the fetus’s chance of developing congenital heart disease. So if you are planning a pregnancy, it is important for you to consider the following factors:

Avoid drinking alcohol

Quit smoking and using all kinds of tobacco products

Avoid secondhand smoke as much as possible

Avoid all forms of recreational drugs

Preseptal cellulitis is also known as periorbital cellulitis, an infection that affects the tissues surrounding the eyes. Preseptal cellulitis causes mainly include insect bites or other kinds of minor trauma or the spread of sinus and other infections. It causes swelling and redness of the eyelid and the skin around the eyes.  Preseptal cellulitis can be treated effectively with close monitoring and antibiotics. However, it may be serious if ignored and left untreated. It may lead to permanent vision problems as well as blindness if the infection spreads to the eye socket. Therefore to prevent complications, prompt diagnosis and treatment are crucial. 

Symptoms of Preseptal Cellulitis 

Eye pain

Redness around the eyelid

Swelling of the eyelid and the area surrounding the eye

Low-grade fever

Primary Causes of Preseptal Cellulitis

Viruses

Bacteria

Fungi

Helminths, also known as parasitic worms

Most of the preseptal cellulitis causes are due to infection caused by bacteria. These bacterial infections can spread from sinus infections or from other parts of the eye. In addition, it can also occur due to minor trauma to a person’s eyelids such as scratches or bug bites. After minor injuries, bacteria can enter this wound and cause infections. Streptococcus, Staphylococcus and Haemophilus influenzae are the most common bacteria that cause this condition. Preseptal cellulitis is more commonly seen in children as they are at a higher risk for infection. The primary treatment includes antibiotics that may be given intravenously or orally. The kind of antibiotics given usually depend on a person’s age and whether the type of bacteria causing the infection has been identified.
