Diseases with their symptoms

Tonsillitis

2025-10-12T20:48:00.004+01:00

What is it?

Tonsillitis is a very common type of infection among children, and less common in adults. The condition causes inflammation of the throat and tonsils and is caused by different types of viruses or bacteria. Group A streptococci, responsible for streptococcal tonsillitis, are the most common.

This type of bacteria can also live in the nose and throat without causing any illness and can infect another person through contact with the bacteria, either through coughing or simply sneezing from an infected person.

Main Causes

The tonsils are the lymphatic tissue responsible for eliminating bacteria and microorganisms that can enter the body and cause infections. They are located at the back or inside of the mouth and in the upper throat. The most common cause of tonsillitis is not just contact with the secretions of an infected person. The use of glass cups and cutlery, as well as contact with wounds infected with group A streptococcus on the skin, are also sources of infection. Bacterial tonsillitis occurs less frequently than its viral form, but any of them can cause complications if not treated properly. The microorganisms that most affect humans when it comes to tonsillitis are: Group A Streptococcus, Epstein-Barr virus, Influenza virus, Herpes simplex virus, Adenovirus, Enterovirus, Parainfluenza virus, and Paraflu virus.

How to identify

The most common symptoms of the condition are:

Inflammation of the tonsils, cervical adenopathy (enlarged lymph nodes) with pain, Ulceration, and the appearance of white or yellow areas on the tonsils. Sore throat that usually lasts more than 48 hours, especially when the mouth is open or solid foods and liquids are ingested. Difficulty swallowing, also called dysphagia. Cough Excessive saliva production, loss of speech, Headache, pain extending to the ears and eyes, Fever and chills, Jaw and throat sensitivity, Bad breath, Nasal congestion and runny nose, Abdominal pain, Bleeding tonsils. One of the complications that can occur if the tonsils are very large is possible respiratory problems, although this is not very common. Tonsil pain is the main symptom of tonsillitis.

How to prevent it

To prevent infection, the following recommendations should be followed: Wash your hands frequently, especially after using the bathroom and before eating. Avoid sharing food, cups, and utensils. Stay away from people who may be infected, especially when they sneeze or cough. Some bad habits not only reduce the effectiveness of the immune system but also cause significant damage to the body, making the patient more likely to develop tonsillitis. Some of these bad habits are smoking (even when the individual is exposed to secondhand smoke) and alcohol abuse. These habits irritate the mucous membranes, which play a fundamental role in the well-being of these tissues.

Types

Tonsil infections are classified according to the duration of symptoms and the causative source: virus or bacteria.

Viral tonsillitis: The Epstein-Barr virus causes most cases of the disease. The infection is diagnosed through a blood test that determines whether the white blood cell count is elevated or if the cells are abnormal. Treatment focuses on reducing inflammation.

Bacterial tonsillitis: When group A Streptococcus bacteria is the likely cause of the infection, a throat swab is taken to confirm the presence of the bacteria.

Acute tonsillitis: when the infection lasts up to 3 months.

Chronic tonsillitis: When the infection lasts more than 3 months or is recurrent. This is a much more serious infection that is neglected by the patient, becoming recurrent and affecting and inflaming the tonsil tissue with disturbing frequency. Due to the severity and level of infection, chronic tonsillitis often leads to pharyngitis.

What tests are used for diagnosis?

Initially, the specialist performs a scan of the patient's mouth and throat to observe the condition of the tonsils. A person usually presents with tonsillitis if the tonsils are red or have white patches. Another visual and physical test that can be used to confirm the diagnosis is when the lymph nodes in the jaw and neck are swollen and tender to the touch. The otolaryngologist may also choose to perform a rapid strep test, but this is not a completely reliable method due to its extreme urgency. Another option is to send a sample of the inflamed pharyngeal tissue to the laboratory, although the results may take a few days.

How is treatment performed?

Painless tonsil infections do not require treatment, although the otolaryngologist may ask the patient to return to the office for a follow-up examination. If the test results are positive, the patient will be prescribed antibiotics and anti-inflammatories, which should be taken even after symptoms subside, as directed by the specialist. In cases where infections are recurrent or abscesses develop, the otolaryngologist may opt to remove the tonsils through a tonsillectomy, which in some cases is performed using radiofrequency, minimizing post-surgical symptoms and potential complications.

Home Treatments

To reduce throat pain, the patient is advised to follow some simple instructions at home: Drink cold liquids or eat ice cream. Although it may seem strange, it's important that the liquids you drink aren't hot, as they can intensify the pain. Gargling with warm water and salt also reduces the burning sensation (we've listed some solutions below). Maintaining adequate hydration is essential. One of the most effective and popular methods used at home is to keep the child in the bathroom with the steam from the shower for a few minutes. This not only moisturizes the throat, but also moistens the respiratory mucosa. As a complement to the treatment prescribed by an otolaryngologist, individuals can also use some home remedies. An excellent home treatment for tonsillitis is gargling. Gargling is effective in facilitating hydration and compensating for the loss of salts and fluids caused by sweat and the high temperature of a fever. Gargling also relieves a sore throat. The best gargling mixtures are: honey and lemon, boiled water with sea salt, water and red pepper, chamomile and honey.

Is tonsillitis contagious? Yes, tonsillitis can be more or less contagious, depending on the causative agent. If it's a virus, it can usually be transmitted to someone who hasn't had contact with the virus before. In the case of bacteria, the condition is easily transmitted, especially by group A Streptococcus. In cases where the individual suffers from chronic tonsillitis or is caused by other conditions, such as sinusitis or allergic rhinitis, it is generally not contagious.

Throat

Protect it well. With sudden fluctuations in temperature, the organs of the respiratory system are most exposed to viruses. At these times, it's important to protect the throat, as it's a sensitive area and the first entry point for air and, therefore, microorganisms.

Phenylketonuria

2025-10-11T23:51:00.002+01:00

Phenylketonuria is an inborn error of metabolism caused by a deficiency of the enzyme phenylalanine hydroxylase, the enzyme responsible for catalyzing the conversion of the essential amino acid phenylalanine to the amino acid tyrosine. Due to the enzyme deficiency, phenylalanine accumulates, which is toxic to the central nervous system.

The enzyme deficiency is caused by mutations in the PAH gene. Both alleles of the gene must carry the mutation, making it an autosomal recessive condition.

In its classic form, if not treated correctly, phenylketonuria can lead to severe intellectual disability, as well as microcephaly, seizures, behavioral changes, and eczema. Symptoms develop over the months after birth as phenylalanine accumulation increases.

There are milder forms of the condition, which vary according to phenylalanine levels.

Diagnosis

Phenylketonuria can be detected early in newborns through the heel prick test, a free test provided by the Unified Health System (SUS) since 1992. It is crucial to perform the test, which should preferably be performed between the third and fifth days of the baby's life. If an increase in serum phenylalanine levels is identified, a protocol for diagnostic confirmation and treatment is initiated.

Treatment

Phenylketonuria is primarily treated with a phenylalanine-restricted diet, aiming to reduce serum phenylalanine levels and prevent neurological complications.

Patients should be monitored by a multidisciplinary team, working with a geneticist and nutritionist to prescribe an appropriate diet that meets the patient's needs and does not aggravate the condition.

Pregnant women with phenylketonuria require special monitoring during pregnancy. Phenylalanine accumulation is toxic to the baby and can lead to intrauterine growth restriction, microcephaly, heart defects, and neurological developmental disorders.

Alkaptonuria

2025-10-11T23:32:00.006+01:00

Alkaptonuria is a rare genetic disease caused by a deficiency in the enzyme homogentisate oxidase, which is responsible for the metabolism of homogentisic acid. It is caused by alterations in the HGD gene.

When homogentisic acid accumulates in the body, it is excreted in the urine, resulting in a color.

Symptoms

The main symptoms are: dark urine after exposure to air, hyperpigmented spots on the skin and sclera, and arthritis. The condition can also lead to changes in the heart valves.

Diagnosis

Urinary tests can identify the presence of homogentisic acid. Genetic testing can confirm the diagnosis.

Treatment

There is no cure for the condition. Treatment consists of symptom management and, in some cases, a protein-restricted diet. With proper monitoring and management of complications, the prognosis is good.

The monitoring of these patients by a multidisciplinary team of professionals familiar with the condition is essential.

Achondroplasia

2025-10-11T15:15:00.001+01:00

Achondroplasia is a rare genetic condition caused by alterations in the FGFR3 gene. It occurs in approximately 1 in every 15,000 to 40,000 births worldwide.

It is transmitted in an autosomal dominant fashion, meaning only one altered copy is needed to cause the condition. Most cases occur in individuals with no family history of achondroplasia.

Characteristics

Patients present with short stature, shorter upper and lower limbs in relation to the torso, a prominent forehead, and trident hands.

Additionally, they may present with respiratory problems and spinal cord compression.

Diagnosis

Diagnosis is suspected based on a physical examination and imaging tests and is confirmed by genetic testing that identifies the mutation in the FGFR3 gene.

Treatment

Treatment of achondroplasia is multidisciplinary, with frequent follow-up.

Recently, ANVISA (Brazilian Health Regulatory Agency) approved the drug Vosorotide (VOXZOGO), which aims to increase the growth rate of patients with achondroplasia from 2 years of age. The medication must be prescribed and monitored by a geneticist and a specialized team.

Rare diseases

2025-10-11T15:12:00.001+01:00

According to the Ministry of Health, rare diseases affect up to 65 out of every 100,000 people. Considering that there are between 6,000 and 8,000 different rare diseases, they affect a considerable percentage of the Brazilian population. The World Health Organization (WHO) estimates that 15 million Brazilians have some form of illness that falls into this category.

Because rare diseases are so diverse, affecting different organs and causing distinct symptoms, the National Policy for Comprehensive Care for People with Rare Diseases divided these diseases into two types, based on their characteristics:

Genetic origin: 80% are caused by factors linked to the patient's genetics. Some examples are inborn errors of metabolism (disorders that generally involve the production of enzymes in the body that fail to break down, store, or transport molecules within the body) and congenital or late-onset anomalies (changes that can occur during embryonic development that cause aesthetic deformities or even affect the functions of certain organs/systems).

Non-genetic origin: other diseases that can occur due to environmental factors, such as infectious, inflammatory, autoimmune, and other rare diseases of non-genetic origin.

Cocoa powder/Dark chocolate

2025-10-09T21:40:00.004+01:00

Who would have thought chocolate would be among the heart-healthy foods? However, it's worth noting that only chocolates with a high cocoa content are heart-friendly, as cocoa powder is rich in flavonoids, bioactive compounds with anti-inflammatory and antioxidant properties, and also helps release nitric oxide, responsible for vasodilation and consequent blood pressure reduction.

An interesting fact about cocoa is that although the fruit is also rich in potassium and flavonoids, approximately 70% of the cocoa is discarded in traditional production, leaving only the beans used. Cocoa also increases the production of serotonin, responsible for well-being, and is high in magnesium, a mineral that helps combat depression, insomnia, and anxiety.

Garlic

2025-10-09T21:35:00.000+01:00

Garlic is rich in sulfur compounds, especially allicin, an active compound that acts as a potent antioxidant, bactericide, and anti-inflammatory.

Ana explains that studies indicate that regularly consuming large amounts of raw garlic (about three cloves per day) can help lower LDL cholesterol, promote vasodilation, and thus promote blood pressure control, reducing the risk of acute myocardial infarction.

Purple grapes

2025-10-09T21:29:00.003+01:00

Purple or dark grapes are another good example of a heart-protective food. Grapes contain resveratrol, flavonoids, and phenolic acids, elements with antioxidant action that help raise good cholesterol (HDL) levels and prevent the aggregation of fatty plaques and, consequently, the formation of clots that trigger diseases such as atherosclerosis and thrombosis. They also contribute to the prevention of strokes and diseases caused by inflammatory processes, such as arthritis.

Purple grapes are the raw material for red wine and whole grape juice, two possible ways to incorporate the benefits of grapes into your diet.

"Among wines, red is the most recommended, because the darker the wine, the higher the polyphenol content; however, the amount should not exceed a glass (due to the alcohol content). Whole grape juice, on the other hand, should be consumed in moderation by diabetics due to its high glycemic index," adds Ana.

Oatmeal and strawberries

2025-10-09T21:22:00.000+01:00

Rich in beta-glucan, a type of soluble fiber, oats are a cereal that stands out among other whole grains when it comes to heart health. Beta-glucan helps control blood sugar levels and reduces the risk of coronary heart disease by helping to lower LDL cholesterol. Ideally, consume about three tablespoons of oats per day (approximately half a cup). Oats can be consumed as flakes or bran, sprinkled on fruit, yogurt, salads, or used as flour in bread and cakes, for example.

Avocado

2025-10-09T21:16:00.001+01:00

This is one of the most controversial fruits, as many still consider it fatty and high in calories. What few know is that avocados are rich in monounsaturated fats and a source of potassium, an important mineral for controlling blood pressure, says Ana.

Monounsaturated fats, like polyunsaturated fats, are linked to lowering LDL cholesterol (the "bad" cholesterol) and reducing cardiovascular risk. It's worth noting that it's best to consume the fruit raw and avoid consuming avocados with sugar.

Fish

2025-10-09T21:08:00.001+01:00

Coldwater fish such as tuna, herring, halibut, salmon, and the popular sardine are high in omega-3, a polyunsaturated fat that helps control blood pressure, cholesterol, and triglycerides, and is also considered a natural anti-inflammatory.

These fish stand out and are considered great heart-healthy because they feed on marine algae rich in polyunsaturated fats, which makes this nutrient present in their composition, unlike freshwater fish, which, as nutritious as they are, lack the much-loved omega-3, Ana emphasizes.

Many studies have linked frequent consumption (about three times a week) of these fish to a significant reduction in the risk of cardiovascular disease.

Extra virgin olive oil

2025-10-09T20:56:00.003+01:00

Olive oil is a food with high concentrations of monounsaturated fats (omega-9) and polyunsaturated fats (omega-6), which help reduce LDL cholesterol and triglyceride levels.

"The best option is to consume the extra-virgin version (with acidity up to 0.05%), as it has a higher concentration of antioxidants," Ana advises.

It's important to note that monounsaturated and polyunsaturated fats are sensitive to heat and light, which can promote oxidation and the consequent loss of antioxidants. Therefore, the best way to consume it is raw (uncooked), and keep it in the cupboard, protected from light and heat.

Not everyone dreams colorful

2020-04-21T22:37:00.003+01:00

It is known that 12% of people dream exclusively in black and white. For the rest, the images that appear during sleep are always colored. Interestingly, studies carried out between 1915 and 1950 pointed out that most people dreamed in black and white, but that started to change after the 1960s. Currently, only 4.4% of the dreams of people under 25 are in black and white. Recent research believes that this is a reflection of the modernization of cinema and television, which has now been shown in color.

All faces are known

2020-04-21T22:37:00.001+01:00

Our brain is not able to invent faces. So, if a stranger appears in the middle of your dreams, know that you have seen this face before. All the features we dream of are real people - whether you remember them or not. As we have contact with thousands of people throughout our lives, our brain has a very large stock of characters to

In fact, everyone dreams

2020-04-21T22:36:00.005+01:00

If you hear people reporting their dreams, but have never been able to do the same thing, don't be fooled! Everyone has the ability to dream (except extreme cases of psychological problems), and if you think you don't have that experience, it's because you are simply forgetting your dreams.

Blind people also dream

2020-04-21T22:36:00.003+01:00

People who became blind only after birth can see images in their dreams. Those born with this condition, on the other hand, do not see images, but are able to dream and have sensations - sounds, smells and emotions - just like anyone else.

It's normal to forget about dreams

2020-04-21T22:36:00.001+01:00

Have you noticed how difficult it is to remember a dream? This is because we usually forget about half a dream five minutes after we wake up. And after a period of 10 minutes, you have already forgotten about 90% of what you dreamed.

Keep check-up up to date

2020-04-19T15:15:00.005+01:00

Taking care of health has no age! A cardiological evaluation is important at any stage of life. Nowadays, due to the quality and pace that we live, the stress and problems of everyday life, prevention must start early. If you are 20, 30 years old and have never noticed any symptoms, keep your check-up up to date. Do not leave to see a doctor only when you feel something very wrong. Some diseases are discovered unintentionally, but at an early stage, which increases the chance of treatment and faster recovery. Take advantage of this beginning of the year to see if everything is right with your health, especially that of your heart.

Pay attention to risk factors

2020-04-19T15:15:00.003+01:00

If, on the one hand, there are those who have the diagnosis and neglect the recommendations, on the other there are those who ignore risk factors and prefer to maintain habits that may be harmful to the heart in the future. Therefore, it is important to highlight: smoking, obesity, physical inactivity, alcohol abuse, unhealthy diets can trigger heart problems. And the greater the number of risk factors combined, the greater the chances of developing heart disease.

Follow medical recommendations

2020-04-19T15:15:00.001+01:00

People who have high blood pressure, diabetes, dyslipidemia (presence of high levels of lipids - fats - in the blood) and cardiovascular problems are the ones who should pay special attention to health throughout the year. Those who have these diseases need to be aware and make the appropriate control, not being able to afford to temporarily suspend or take medications irregularly, since any carelessness can be very harmful and have serious consequences. There are certain diseases in which it is not enough to take a medication for a certain period and simply stop the body from reacting well. It is necessary to follow the treatment, with adaptations in lifestyle, food, living environment and the use of medicines. To scale the problem, the lack of control of blood pressure or cholesterol for long periods can lead to risks of stroke and degeneration of coronary arteries or other vascular systems. In the case of diabetes treatment, not paying due attention to medical recommendations regarding diet, medication and physical activity and remaining with high levels of glycated hemoglobin may not present immediate problems, but in the long term there are risks of developing ischemia, insufficiency kidney disease, diabetic retinopathy, coronary artery disease, among others.

Put laziness aside

2020-04-19T15:14:00.003+01:00

Here comes that old recommendation: practice physical activities! It may even sound cliché, but not everyone follows this idea, so it is always necessary to reinforce. Regular exercise contributes to physical and mental well-being, helps control obesity, pressure and diabetes, reduces stress, among other benefits. If you don't have time or have not yet found the courage to enter a gym or practice a sport regularly, include more movement in your daily life: prefer the stairs over the elevator; go out to dance; use the energy of the children who are present in your daily life to play; make walking routes - even if they are short; remember to take breaks during working hours and take the time to stretch and walk around the office; Before getting out of bed, stretch your body and spend a few minutes on stretching and flexibility exercises. The possibilities are endless. Use your creativity and keep laziness away!

Having a pet at home

2020-04-19T15:14:00.001+01:00

Did you know that pets can contribute to your heart health? It is scientifically proven that pets are strongly associated with the control of risk factors for heart disease, such as obesity, high blood pressure, high levels of triglycerides and cholesterol. Contact with animals stimulates the production of several good hormones, such as endorphins, prolactins and oxytocins, substances that act in the regulation of cortisol (hormone related to the alertness), which contributes to the fight against stress. Also released in the body due to this human-animal interaction, acetylcholine acts to reduce blood pressure, heart rate and respiratory rate. The feeling of well-being, happiness and comfort generated in this interaction results in a decrease in adrenaline levels - a substance linked to increased blood pressure. Having a pet at home still inhibits the feeling of social isolation. Loneliness, anxiety and depression are other factors that trigger problems in the cardiovascular system that living with pets minimizes.

Having good relationships and taking care of emotions

2020-04-18T15:55:00.005+01:00

Family, friends, companions ... the relationships and the environment in which we live interfere - a lot! - in maintaining our health, not only physical, but also mental. Emotions related to love, joy, happiness and good humor lead to muscle relaxation, vasodilation, intestinal relaxation, glandular secretion, salivation, heat without sweating, that is, manifestations that help prevent cardiovascular diseases. In this sense, it is important to pay attention to your circle of coexistence, to what you have been reading and watching. Evaluate your relationships, do some research to find interesting websites, films and constructive books that will add positive things to your life. Some studies have already revealed that the brain registers and is influenced when we focus only on bad news, programs and films of violence or that stimulate our negative feelings and emotions.

Think positive

2020-04-18T15:55:00.003+01:00

Starting a new cycle with a positive mind can make all the difference when it comes to health. Studies show that emotions and thoughts directly interfere with the chemistry, production and release of hormones and the functioning of the body as a whole. Feelings can influence, for example, cholesterol, hypertension, the evolution of coronary heart disease and the immune system. Optimistic people tend to cope better with stress, have healthier habits, in addition to having better adherence to treatments for chronic diseases and the need for surgery, understanding the need for intervention and directing their focus on getting well and not on risks.

Floss

2020-04-18T15:55:00.001+01:00

Research by scientists in Italy and the UK, published on the Jornal da Faseb website ("The Federation of American Societies for Experimental Biology"), shows that infected gums can be a risk factor for developing heart problems . In fact, proper dental hygiene can reduce the risk of atherosclerosis, stroke and heart disease, regardless of other measures, such as cholesterol control. "It has long been suspected that atherosclerosis is an inflammatory process and that periodontal disease plays an important role in atherosclerosis", says Mario Clerici, researcher of the study.
