The posterior nasal nerve plays an important role on cardiopulmonary reflexes to nasal application of capsaicin, distilled water and l-menthol in anesthetized dogs. (1/983)
The sensory innervation of the cardiopulmonary reflexes to nasal application of capsaicin (CAPS), distilled water (DW) and l-menthol (LM) was studied in anesthetized dogs breathing through tracheostomy. A marked cardiopulmonary reflex was observed by CAPS and DW into the nasal cavity, while a prolongation of expiration was induced by LM. All these reflexes were significantly decreased by bilateral section of the posterior nasal nerve (PNN) and completely abolished by topical nasal anesthesia with lidocaine. Responses of the whole nerve activity of the PNN to these substances corresponded to the magnitude of the reflexes. These results indicate that PNN afferents play an important role on the reflex elicitation of the noxious, water and cold stimuli from the nasal cavity. (+info)Nasal nitric oxide concentration in paranasal sinus inflammatory diseases. (2/983)
In normal upper airways, nitric oxide is generated by the paranasal sinus epithelium and then diffuses into the nasal cavities. This study examined whether or not nasal NO concentration is affected by paranasal sinus inflammatory diseases. The influence of obstruction (nasal polyposis) and/or inflammation (allergy or chronic sinusitis) of the paranasal sinuses on nasal NO concentration was evaluated in nasal allergic (n=7 patients) or nonallergic (n=20) polyposis, nonallergic chronic sinusitis (n=10) and Kartagener's syndrome (n=6) and compared with control subjects (n=42). A score of alteration of the paranasal sinus (number of altered and occluded sinuses) was determined by a computed tomography scan. The nasal NO concentration in nasal nonallergic polyposis (150+/-20 parts per billion (ppb)) was significantly decreased compared with both controls (223+/-6 ppb, p=0.01) and polyposis with allergy (272+/-28 ppb, p<0.0001). In each group, the nasal NO concentration was inversely correlated with the extent of tomodensitometric alteration of the paranasal sinuses. In Kartagener's syndrome, the nasal NO concentration (14+/-2 ppb) was drastically decreased compared with all other groups, despite the presence of open paranasal sinuses. Thus, the nasal NO concentration in patients with nasal polyposis appeared to be dependent on both the allergic status and the degree of obstruction of the paranasal sinuses. (+info)Salivary contribution to exhaled nitric oxide. (3/983)
Dietary and metabolic nitrate is distributed from the blood to the saliva by active uptake in the salivary glands, and is reduced to nitrite in the oral cavity by the action of certain bacteria. Since it has been reported that nitric oxide may be formed nonenzymatically from nitrite this study aimed to determine whether salivary nitrite could influence measurements of exhaled NO. Ten healthy subjects fasted overnight and ingested 400 mg potassium nitrate, equivalent to approximately 200 g spinach. Exhaled NO and nasal NO were regularly measured with a chemiluminescence technique up to 3 h after the ingestion. Measurements of exhaled NO were performed with a single-breath procedure, standardized to a 20-s exhalation, at a flow of 0.15 L x s(-1), and oral pressure of 8-10 cmH2O. Values of NO were registered as NO release rate (pmol x s(-1)) during the plateau of exhalation. Exhaled NO increased steadily over time after nitrate load and a maximum was seen at 120 min (77.0+/-15.2 versus 31.2+/-3.0 pmol x s(-1), p<0.01), whereas no increase was detected in nasal NO levels. Salivary nitrite concentrations increased in parallel; at 120 min there was a four-fold increase compared with baseline (1.56+/-0.44 versus 0.37+/-0.09 mM, p<0.05). The nitrite-reducing conditions in the oral cavity were also manipulated by the use of different mouthwash procedures. The antibacterial agent chlorhexidine acetate (0.2%) decreased NO release by almost 50% (p<0.01) 90 min after nitrate loading and reduced the preload control levels by close to 30% (p<0.05). Sodium bicarbonate (10%) also reduced exhaled NO levels, but to a somewhat lesser extent than chlorhexidine acetate. In conclusion, salivary nitric oxide formation contributes to nitric oxide in exhaled air and a large intake of nitrate-rich foods before the investigation might be misinterpreted as an elevated inflammatory activity in the airways. This potential source of error and the means for avoiding it should be considered in the development of a future standardized method for measurements of exhaled nitric oxide. (+info)Protection against influenza virus infection of mice fed Bifidobacterium breve YIT4064. (4/983)
Mice fed Bifidobacterium breve YIT4064 and immunized orally with influenza virus were more strongly protected against influenza virus infection of the lower respiratory tract than ones immunized with influenza virus only. The number of mice with enhanced anti-influenza virus immunoglobulin G (IgG) in serum upon oral administration of B. breve YIT4064 and oral immunization with influenza virus was significantly greater than that upon oral immunization with influenza virus only. These findings demonstrated that the oral administration of B. breve YIT4064 increased anti-influenza virus IgG antibodies in serum and protected against influenza virus infection. The oral administration of B. breve YIT4064 may enhance antigen-specific IgG against various pathogenic antigens taken orally and induce protection against various virus infections. (+info)Capsaicin-sensitive C-fiber-mediated protective responses in ozone inhalation in rats. (5/983)
To assess the role of lung sensory C fibers during and after inhalation of 1 part/million ozone for 8 h, we compared breathing pattern responses and epithelial injury-inflammation-repair in rats depleted of C fibers by systemic administration of capsaicin as neonates and in vehicle-treated control animals. Capsaicin-treated rats did not develop ozone-induced rapid, shallow breathing. Capsaicin-treated rats showed more severe necrosis in the nasal cavity and greater inflammation throughout the respiratory tract than did control rats exposed to ozone. Incorporation of 5-bromo-2'-deoxyuridine (a marker of DNA synthesis associated with proliferation) into terminal bronchiolar epithelial cells was not significantly affected by capsaicin treatment in rats exposed to ozone. However, when normalized to the degree of epithelial necrosis present in each rat studied, there was less 5-bromo-2'-deoxyuridine labeling in the terminal bronchioles of capsaicin-treated rats. These observations suggest that the ozone-induced release of neuropeptides does not measurably contribute to airway inflammation but may play a role in modulating basal and reparative airway epithelial cell proliferation. (+info)LMR spectroscopy: a new sensitive method for on-line recording of nitric oxide in breath. (6/983)
Laser magnetic resonance spectroscopy (LMRS) is a sensitive and isotope-selective technique for determining low concentrations of gaseous free radicals with high time resolution. We used this technique to analyze the nitric oxide (NO) concentration profile while simultaneously measuring the flow and expired volume during several single breathing cycles. Eight healthy, nonallergic volunteers were investigated. An initial NO peak was found in all breathing cycles before the NO concentration dropped to a relatively stable plateau in the late phase of expiration. The nasal NO peak was significantly higher than the oral NO peak. The nasal NO plateau was always higher than the oral NO plateau. The height of the initial nasal and oral NO peak rose with increasing duration of breath hold, whereas the late expiratory NO plateau changed only little for either the nasal or the oral breathing cycles. Our findings demonstrate, in line with other reports using other techniques, that the nose is the primary source for NO within the airways. (+info)Anatomical structure and surface epithelial distribution in the nasal cavity of the common cotton-eared marmoset (Callithrix jacchus). (7/983)
To validate use of the common cotton-eared marmoset (Callithrix jacchus) in inhalation toxicity studies, its nasal morphology was examined. The nasal turbinates each consisted of one maxilloturbinate and one ethmoturbinate: these were more planar in structure than the comparable structures of rodents or dogs. The nasal cavity epithelia comprised squamous epithelium (SE), nasal transitional epithelium (NTE), respiratory epithelium (RE) and olfactory epithelium (OE), listed in order of occurrence from anterior to posterior positions. NTE was distributed as a narrow band lying between SE and RE. OE was limited to the dorsal part of the cavity, which was structurally similar to that of the macaque or man. Overall, this study revealed structural the similarity of the whole nasal cavity in the marmoset to that of macaques or humans. Prediction of nasal cavity changes in man based on extrapolation from experimentally induced changes in the common marmoset therefore seems likely to be feasible, making it a useful animal model for inhalation studies. (+info)Evidence for nasal carriage of methicillin-resistant staphylococci colonizing intravascular devices. (8/983)
Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same species as the CVC isolates. Of the 33 same-species isolates, 20 appeared to be identical strains by pulsed-field gel electrophoresis analysis. These data suggest that measures should be taken to reduce cross-contamination between the respiratory tract and intravascular devices. However, the potential interest in detecting methicillin-resistant coagulase-negative staphylococcus carriage in high-risk patients is hampered by the lack of sensitivity of nasal surveillance cultures. (+info)Nose neoplasms refer to any type of abnormal growth or tumor that develops in the nose or nasal passages. These tumors can be benign (non-cancerous) or malignant (cancerous), and they can affect people of all ages.
Types of Nose Neoplasms[2]

6. Deviated septum: This is a condition where the thin wall of cartilage and bone that separates the two sides of the nasal passages is displaced, causing difficulty breathing through the nose.
7. Nasal dryness: This can be caused by a variety of factors, such as dry air, allergies, or certain medications. It can lead to symptoms such as nasal congestion and difficulty breathing through the nose.
8. Nasal fractures: These are breaks in the bones of the nose, which can be caused by trauma such as a blow to the face. They can cause symptoms such as pain, swelling, and difficulty breathing through the nose.
9. Sinusitis: This is an inflammation of the sinuses, which are air-filled cavities in the skull. It can cause symptoms such as facial pain, headaches, and congestion.
10. Nasal polyps: These are growths that occur in the nasal passages and can cause symptoms such as nasal congestion, loss of sense of smell, and facial pain. They can be caused by a variety of factors, including allergies and chronic sinusitis.
These are just a few examples of the many different conditions that can affect the nose. If you are experiencing symptoms such as nasal congestion, loss of sense of smell, or facial pain, it is important to see a healthcare professional for proper diagnosis and treatment.
Paranasal sinus neoplasms refer to tumors or abnormal growths that occur within the paranasal sinuses, which are air-filled cavities within the skull that drain into the nasal passages. These neoplasms can be benign or malignant and can affect various structures in the head and neck, including the sinuses, nasal passages, eyes, and brain.
Types of Paranasal Sinus Neoplasms:
There are several types of paranasal sinus neoplasms, including:
1. Nasal cavity squamous cell carcinoma: This is the most common type of paranasal sinus cancer and arises from the lining of the nasal cavity.
2. Maxillary sinus adenoid cystic carcinoma: This type of tumor is slow-growing and usually affects the maxillary sinus.
3. Esthesioneuroepithelioma: This rare type of tumor arises from the lining of the nasal cavity and is more common in women than men.
4. Sphenoid sinus mucocele: This type of tumor is usually benign and occurs in the sphenoid sinus.
5. Osteochondroma: This is a rare type of benign tumor that arises from the bone and cartilage of the paranasal sinuses.
Symptoms of Paranasal Sinus Neoplasms:
The symptoms of paranasal sinus neoplasms can vary depending on the size, location, and type of tumor. Common symptoms include:
1. Nasal congestion or blockage
2. Headaches
3. Pain or pressure in the face, especially in the cheeks, eyes, or forehead
4. Double vision or other vision problems
5. Numbness or weakness in the face
6. Discharge of fluid from the nose or eyes
7. Swelling of the eyelids or face
8. Coughing up blood
Diagnosis of Paranasal Sinus Neoplasms:
The diagnosis of paranasal sinus neoplasms is based on a combination of physical examination, imaging studies, and biopsy. The following tests may be used to help diagnose a paranasal sinus tumor:
1. Computed tomography (CT) scan or magnetic resonance imaging (MRI): These imaging tests can provide detailed pictures of the paranasal sinuses and any tumors that may be present.
2. Endoscopy: A thin, lighted tube with a camera on the end can be inserted through the nostrils to examine the inside of the nasal cavity and paranasal sinuses.
3. Biopsy: A sample of tissue from the suspected tumor site can be removed and examined under a microscope to confirm the diagnosis.
4. Nasal endoscopy: A flexible tube with a camera on the end can be inserted through the nostrils to examine the inside of the nasal cavity and paranasal sinuses.
Treatment of Paranasal Sinus Neoplasms:
The treatment of paranasal sinus neoplasms depends on the type, location, size, and aggressiveness of the tumor, as well as the patient's overall health. The following are some of the treatment options for paranasal sinus neoplasms:
1. Surgery: Surgical removal of the tumor is often the first line of treatment for paranasal sinus neoplasms. The type of surgery used depends on the location and extent of the tumor.
2. Radiation therapy: Radiation therapy may be used alone or in combination with surgery to treat paranasal sinus neoplasms that are difficult to remove with surgery or have spread to other parts of the skull base.
3. Chemotherapy: Chemotherapy may be used in combination with radiation therapy to treat paranasal sinus neoplasms that are aggressive and have spread to other parts of the body.
4. Endoscopic surgery: This is a minimally invasive procedure that uses an endoscope (a thin, lighted tube with a camera on the end) to remove the tumor through the nostrils or mouth.
5. Skull base surgery: This is a more invasive procedure that involves removing the tumor and any affected bone or tissue in the skull base.
6. Reconstruction: After removal of the tumor, reconstructive surgery may be necessary to restore the natural anatomy of the skull base and nasal cavity.
7. Observation: In some cases, small, benign tumors may not require immediate treatment and can be monitored with regular imaging studies to see if they grow or change over time.
It is important to note that the most appropriate treatment plan for a patient with a paranasal sinus neoplasm will depend on the specific characteristics of the tumor and the individual patient's needs and medical history. Patients should work closely with their healthcare team to determine the best course of treatment for their specific condition.
Nasal polyps are typically treated with medications such as nasal sprays or oral steroids, which can help reduce inflammation and shrink the size of the polyps. In some cases, surgery may be necessary to remove the polyps or repair any structural damage they have caused.
Here are some key points to note about nasal polyps:
1. They are usually benign: Nasal polyps are not cancerous, and they do not spread to other parts of the body.
2. They can be caused by allergies: Allergic reactions can lead to inflammation in the nasal passages, which can cause polyps to grow.
3. They can be treated with medications: Nasal sprays and oral steroids are commonly used to treat nasal polyps.
4. They can obstruct breathing: Large polyps can block the flow of air through the nasal passages, leading to breathing difficulties.
5. They can cause loss of sense of smell: Polyps can damage the olfactory nerve, which is responsible for our sense of smell.
6. They can be associated with other conditions: Nasal polyps can be a symptom of other conditions such as cystic fibrosis or primary immunodeficiency disorders.
* Nasal polyps: Growths in the nasal passages that can block airflow.
* Deviated septum: A crooked partition between the two sides of the nasal passages that can narrow or block one side.
* Enlarged adenoids or turbinate bones: These structures can grow and obstruct the airway.
* Trauma to the nose: A broken nose or other injury can cause obstruction of the nasal passages.
* Infections such as rhinitis, sinusitis, or allergies: Swelling and congestion in the nasal passages can cause obstruction.
* Nasal tumors: Growths in the nasal passages that can block airflow.
* Anatomical abnormalities: Some people may be born with abnormalities such as a narrow nasal passage or a deviated septum, which can cause nasal obstruction.
Symptoms of Nasal Obstruction include:
* Difficulty breathing through the nose
* Congestion or stuffiness in the nose
* Noise or snoring while breathing
* Sleep disturbances due to difficulty breathing
* Headaches or facial pain due to straining to breathe
* Postnasal drip (a sensation of mucus running down the back of the throat)
* Coughing or sneezing
Treatment for Nasal Obstruction depends on the underlying cause and can include:
* Medications such as nasal decongestants, antihistamines, and steroids to reduce swelling and congestion.
* Nasal strips or dilators to open up the nasal passages.
* Saline nasal irrigation to flush out mucus and debris.
* Surgery to remove nasal polyps, correct a deviated septum, or other structural abnormalities.
* Allergy treatment to reduce inflammation and congestion.
It is important to seek medical attention if you experience persistent or severe symptoms of nasal obstruction as it can lead to complications such as sinus infections, sleep disorders, and other health problems. A healthcare professional can diagnose the underlying cause and recommend appropriate treatment options.
Definition: A nosebleed, also known as a bloody nose, is a common condition that occurs when the nasal passages bleed. It can be caused by a variety of factors, such as dry air, allergies, colds, sinus infections, and injuries to the nose.
Synonyms: Nosebleed, bloody nose, anterior epistaxis, posterior epistaxis.
Antonyms: None.
Epistaxis is a common condition that can be caused by a variety of factors, including:
1. Dry air: Dry air can cause the nasal passages to become dry and cracked, leading to bleeding.
2. Allergies: Seasonal allergies or allergies to dust, pollen, or other substances can cause inflammation and irritation in the nasal passages, leading to bleeding.
3. Colds: A common cold can cause inflammation and congestion in the nasal passages, leading to bleeding.
4. Sinus infections: An infection in the sinuses can cause inflammation and bleeding in the nasal passages.
5. Injuries: Trauma to the nose, such as a blow to the face or a fall, can cause bleeding.
6. Medications: Certain medications, such as aspirin or warfarin, can thin the blood and increase the risk of bleeding.
7. High blood pressure: High blood pressure can cause damage to the blood vessels in the nose, leading to bleeding.
8. Nose picking: Picking or blowing the nose too forcefully can cause trauma to the nasal passages and lead to bleeding.
9. Hereditary hemorrhagic telangiectasia (HHT): A rare genetic disorder that affects the blood vessels and can cause recurring nosebleeds.
Symptoms of epistaxis may include:
1. Blood flowing from one or both nostrils
2. Nasal congestion or stuffiness
3. Pain or discomfort in the nose or face
4. Difficulty breathing through the nose
5. Postnasal drip (mucus running down the back of the throat)
6. Swelling around the eyes or face
7. Fever or chills
8. Headache
9. Weakness or fatigue
If you experience any of these symptoms, it is important to seek medical attention. A healthcare professional can diagnose the cause of the nosebleed and recommend appropriate treatment. Treatment for epistaxis may include:
1. Nasal decongestants or antihistamines to reduce nasal congestion
2. Topical or oral antibiotics to treat any underlying infections
3. Applications of a topical ointment or cream to help protect the nasal passages and promote healing
4. Injectable medications to help constrict blood vessels and stop bleeding
5. Surgery to repair damaged blood vessels or remove any foreign objects that may be causing the bleeding.
The exact cause of OEB is not known, but it is believed to be linked to genetic mutations and exposure to certain environmental factors. The symptoms of OEB can vary depending on the size and location of the tumor, but may include nasal congestion, headaches, seizures, and vision problems.
OEB is diagnosed through a combination of imaging tests such as CT or MRI scans and tissue biopsy. Treatment options for OEB typically involve surgery to remove the tumor, followed by radiation therapy and/or chemotherapy to kill any remaining cancer cells. The prognosis for OEB is generally poor, as it is a rare and aggressive form of cancer that is difficult to treat effectively.
In summary, Olfactory esthesioneuroblastoma (OEB) is a rare type of cancer that originates in the olfactory bulb and/or the nasal cavity, characterized by symptoms such as nasal congestion, headaches, seizures, and vision problems. It is diagnosed through a combination of imaging tests and tissue biopsy, and treated with surgery, radiation therapy, and/or chemotherapy.
Benign maxillary sinus tumors may include:
* Papilloma: A benign growth that resembles a finger-like protrusion and is usually slow-growing and non-aggressive.
* Pyogenic granuloma: A type of benign bacterial infection that can cause localized tissue growth and inflammation.
* Osteoid osteoma: A rare, benign tumor that forms in the bone and can cause pain and swelling.
Malignant maxillary sinus tumors are more aggressive and can include:
* Squamous cell carcinoma: A type of skin cancer that can occur in the maxillary sinus and can be treated with surgery, radiation therapy, or chemotherapy.
* Adenoid cystic carcinoma: A rare, malignant tumor that can grow slowly over time and can be difficult to treat.
* Esthesioneuroblastoma: A rare, malignant tumor that originates in the nasal cavity and can extend into the maxillary sinus.

* Pain or swelling in the face or neck
* Difficulty breathing through the nose
* Nasal congestion or discharge
* Eye problems such as double vision or protrusion
* Headaches or facial pain
The diagnosis of maxillary sinus neoplasms is typically made using a combination of imaging studies, such as CT scans or MRI, and tissue biopsy. Treatment options can range from observation to surgery, radiation therapy, or chemotherapy, depending on the type and stage of the tumor.
There are several types of rhinitis, including:
1. Allergic rhinitis: This type of rhinitis is caused by an allergic reaction to substances such as pollen, dust mites, or pet dander. Symptoms include sneezing, congestion, runny nose, and itchy eyes.
2. Viral rhinitis: This type of rhinitis is caused by a viral infection and can be accompanied by symptoms such as fever, headache, and fatigue.
3. Bacterial rhinitis: This type of rhinitis is caused by a bacterial infection and can be treated with antibiotics. Symptoms include thick yellow or green discharge from the nose and facial pain.
4. Non-allergic rhinitis: This type of rhinitis is not caused by an allergic reaction and can be triggered by factors such as hormonal changes, medications, or environmental irritants. Symptoms include postnasal drip and nasal congestion.
Rhinitis can be diagnosed through a physical examination of the nose and sinuses, as well as through tests such as a nasal endoscopy or imaging studies. Treatment for rhinitis depends on the underlying cause and may include medications such as antihistamines, decongestants, or antibiotics, as well as lifestyle changes such as avoiding allergens or using saline nasal sprays. In severe cases, surgery may be necessary to correct physical abnormalities in the nose and sinuses.
The term "atrophic" refers to the wasting away or degeneration of tissue, which is a hallmark feature of this condition. The atrophy of the nasal mucosa can lead to a decrease in the production of mucus, which can impair the body's ability to fight off infections and allergens.
Rhinitis, atrophic can be caused by a variety of factors, including allergies, viral infections, and exposure to environmental irritants such as smoke or pollution. The condition is more common in older adults and can be associated with other medical conditions such as asthma, sinusitis, and chronic bronchitis.
There are several risk factors for developing rhinitis, atrophic, including:
1. Allergies: People with allergies are more likely to develop rhinitis, atrophic.
2. Age: The condition is more common in older adults.
3. Family history: A family history of allergies or respiratory conditions can increase the risk of developing rhinitis, atrophic.
4. Exposure to environmental irritants: Smoke, pollution, and other environmental irritants can increase the risk of developing the condition.
5. Previous respiratory infections: People who have had previous respiratory infections, such as the common cold or flu, may be more likely to develop rhinitis, atrophic.
There are several symptoms of rhinitis, atrophic, including:
1. Nasal congestion: The nasal passages can become inflamed and congested, making it difficult to breathe through the nose.
2. Rhinorrhea: Thick, yellowish discharge from the nose is a common symptom of rhinitis, atrophic.
3. Postnasal drip: This can cause a sore throat and coughing.
4. Loss of smell: The inflammation in the nasal passages can damage the olfactory nerve, leading to a loss of sense of smell.
5. Sinus pressure: The condition can lead to sinus pressure and pain.
There are several complications of rhinitis, atrophic, including:
1. Chronic sinusitis: The condition can lead to chronic sinusitis, which can cause pain, facial swelling, and difficulty breathing through the nose.
2. Asthma: Some people with rhinitis, atrophic may develop asthma.
3. Middle ear infections: The infection in the nasal passages can spread to the middle ear, leading to ear infections.
4. Meningitis: In rare cases, the infection can spread to the meninges, leading to meningitis.
There are several treatments for rhinitis, atrophic, including:
1. Nasal decongestants: These medications can help reduce swelling in the nasal passages and relieve congestion.
2. Antihistamines: These medications can help reduce nasal discharge and relieve itching.
3. Corticosteroids: These medications can help reduce inflammation in the nasal passages.
4. Antibiotics: If there is a bacterial infection, antibiotics may be prescribed.
5. Saline nasal sprays: These can help moisturize the nasal passages and thin mucus.
6. Humidifiers: Using a humidifier can help keep the nasal passages moist and relieve congestion.
7. Nasal strips: These can help open up the nasal passages and improve breathing.
8. Surgery: In severe cases, surgery may be necessary to remove polyps or correct anatomical abnormalities.
It is important to note that these treatments may not completely cure the condition, but they can help manage the symptoms and prevent complications. It is also important to work with a healthcare professional to determine the best course of treatment for your specific case.
The most common paranasal sinus diseases include:
1. Acute Sinusitis: This is an infection of the paranasal sinuses that can be caused by a virus or bacteria. Symptoms include fever, headache, and facial pain or pressure.
2. Chronic Sinusitis: This is a persistent infection of the paranasal sinuses that can last for more than 12 weeks. Symptoms are similar to acute sinusitis, but may be less severe.
3. Rhinosinusitis: This is an inflammation of the nasal passages and paranasal sinuses that can be caused by infection or allergies. Symptoms include nasal congestion, facial pain or pressure, and headache.
4. Nasal Polyps: These are growths that occur in the lining of the nasal passages or paranasal sinuses. They can cause blockage of the nasal passages and sinuses, leading to breathing difficulties and other symptoms.
5. Cerebral Abscess: This is a collection of pus in the brain that can be caused by an infection that spreads from the paranasal sinuses. Symptoms include fever, headache, and neurological problems such as confusion or seizures.
6. Meningitis: This is an infection of the protective membranes (meninges) that cover the brain and spinal cord. It can be caused by bacteria or viruses and can lead to serious complications if left untreated.
7. Osteomyelitis: This is an infection of the bones of the face, which can be caused by spread of infection from the paranasal sinuses. Symptoms include facial pain, swelling, and difficulty moving the affected area.
8. Orbital Cellulitis: This is an infection of the tissues surrounding the eye that can be caused by spread of infection from the paranasal sinuses. Symptoms include protrusion of the eye, swelling of the eyelid, and difficulty moving the affected eye.
9. Endophthalmitis: This is an infection of the interior of the eye that can be caused by spread of infection from the paranasal sinuses. Symptoms include sudden severe pain, redness, and vision loss.
10. Cranial Nerve Palsy: This is a condition where one or more of the cranial nerves are affected by an infection, leading to symptoms such as double vision, drooping eyelid, or weakness of the facial muscles.
It's important to note that these complications can be serious and potentially life-threatening, so it's important to seek medical attention immediately if you experience any of these symptoms. Early diagnosis and treatment can help prevent or reduce the risk of these complications.
* Nasal congestion and discharge
* Headaches
* Pain and pressure in the face, particularly in the cheeks and forehead
* Fatigue and fever
* Loss of smell or taste
There are several types of sinusitis, including:
* Acute sinusitis: This type of sinusitis is caused by a sudden infection and typically lasts for less than four weeks.
* Chronic sinusitis: This type of sinusitis is caused by a long-term infection or inflammation that persists for more than 12 weeks.
* Recurrent sinusitis: This type of sinusitis occurs when acute sinusitis keeps coming back, often due to repeat infections or allergies.
* Allergic fungal sinusitis: This type of sinusitis is caused by an allergic reaction to fungus that grows in the sinuses.
* Chronic rhinosinusitis: This type of sinusitis is characterized by chronic inflammation and nasal congestion, often due to an allergic response.
Treatment for sinusitis depends on the underlying cause and may include antibiotics, antihistamines, decongestants, nasal saline irrigations, or surgery. It is important to seek medical attention if symptoms persist or worsen over time, as untreated sinusitis can lead to complications such as meningitis or brain abscess.
Pasteurella infections are more common in people who work closely with animals, such as veterinarians, farm workers, and pet owners. The bacteria can enter the body through open wounds, cuts, or abrasions, and it can cause a variety of illnesses, including:
1. Pasteurellosis: A respiratory infection caused by Pasteurella multocida, which is common in dogs and cats. It can be transmitted to humans through close contact with infected animals.
2. Pneumonia: A type of lung infection that can be caused by Pasteurella multocida, especially in people with weakened immune systems or pre-existing respiratory conditions.
3. Sinusitis: An infection of the sinuses, which are air-filled cavities in the skull, can be caused by Pasteurella multocida.
4. Cellulitis: A bacterial infection of the skin and underlying tissue that can be caused by Pasteurella multocida.
5. Endocarditis: An infection of the inner lining of the heart, which is rare but can be caused by Pasteurella multocida.
The symptoms of Pasteurella infections can vary depending on the type of infection and the severity of the illness. Common symptoms include fever, cough, difficulty breathing, chills, headache, and fatigue. In severe cases, Pasteurella infections can lead to life-threatening complications such as sepsis or meningitis.
Diagnosis of Pasteurella infections typically involves a combination of physical examination, medical history, and laboratory tests, including blood cultures, chest X-rays, and CT scans. Treatment usually involves antibiotics to eradicate the bacteria, as well as supportive care to manage symptoms and prevent complications.
Prevention of Pasteurella infections primarily involves avoiding contact with animals that may carry the bacteria, as well as good hygiene practices such as handwashing and covering wounds. In some cases, antibiotics may be prescribed to prevent infection in high-risk individuals, such as those with weakened immune systems or pre-existing respiratory conditions.

The exact cause of rhinoscleroma is not well understood, but it is believed to be associated with chronic infection, allergies, and exposure to environmental irritants such as dust, smoke, and pollution. The condition typically affects adults between the ages of 30-60 years old and may have a slight predilection for males.
Symptoms of rhinoscleroma can include nasal congestion, thick yellow or greenish discharge, postnasal drip, loss of sense of smell, facial pain and pressure, headaches, and coughing. The condition can also lead to complications such as meningitis, sepsis, and bone infections if left untreated.
Rhinoscleroma is diagnosed through a combination of physical examination, nasal endoscopy, imaging studies such as CT or MRI scans, and cultures of nasal secretions. Treatment options for rhinoscleroma include antibiotics, nasal decongestants, antihistamines, corticosteroids, and surgery to remove affected tissue and improve nasal breathing.
It is important to seek medical attention if symptoms persist or worsen over time, as rhinoscleroma can have a significant impact on quality of life and may lead to serious complications if left untreated.
Inverted Papillomas are usually small, ranging in size from a few millimeters to about 1 centimeter in diameter. They can be either solitary (singular) or multiple and are most commonly found in the ethmoid sinuses, which are air-filled cavities in the skull located between the eyes and nasal passages.
Symptoms of Inverted Papilloma may include:
* Nasal congestion or blockage
* Nasal discharge (rhinorrhea)
* Postnasal drip
* Loss of sense of smell
* Headaches
* Sinus pressure or pain
* Coughing
* Sneezing
Inverted Papillomas are usually diagnosed through a procedure called nasal endoscopy, which involves inserting a flexible tube with a camera into the nostrils to visualize the inside of the nasal passages and sinuses. A biopsy may also be taken to confirm the diagnosis.
Treatment for Inverted Papilloma usually involves surgical removal of the tumor, either through traditional open surgery or endoscopic surgery, which is less invasive. In some cases, radiation therapy may be recommended to ensure that all of the tumor cells are removed.
Overall, Inverted Papilloma is a rare but treatable condition that can cause significant symptoms and discomfort. If you experience any of the symptoms listed above or have concerns about your nasal health, it's important to consult with an ear, nose, and throat (ENT) specialist for proper evaluation and treatment.
Angiomyomas can be classified into several types based on their location and the type of blood vessel from which they originate. The most common types are:
1. Capillary angiomyoma: These are the most common type of angiomyoma and occur in the skin and subcutaneous tissue. They are usually small, round or oval-shaped, and may be pink, red, or purple in color.
2. Cavernous angiomyoma: These are larger than capillary angiomyomas and occur in the deeper layers of the skin and subcutaneous tissue. They may be more tender to the touch and can cause swelling or bruising if they become injured.
3. Venous angiomyoma: These occur in the veins and can cause symptoms such as swelling, pain, and bruising.
4. Lymphatic angiomyoma: These occur in the lymphatic vessels and are rare.
The exact cause of angiomyomas is not known, but they tend to run in families and may be associated with certain genetic conditions, such as hereditary hemorrhagic telangiectasia (HHT). Angiomyomas can also occur spontaneously without any known cause.
Treatment for angiomyomas usually involves monitoring the tumor for changes and only intervening if it becomes symptomatic or if it is causing cosmetic concerns. In some cases, treatment may involve surgery to remove the tumor or laser therapy to shrink the size of the tumor.
Perennial allergic rhinitis can be caused by a variety of allergens, including:
1. Dust mites: These tiny organisms live in bedding, carpets, and upholstered furniture and feed on human skin cells. Their waste products are the primary allergen that triggers an allergic reaction.
2. Mold: This type of fungus grows in damp environments and can be found in basements, bathrooms, and outdoors.
3. Pet dander: The dead skin flakes from animals such as cats, dogs, and birds can trigger an allergic reaction in some people.
4. Insect bites: Some people may experience an allergic reaction to the saliva or venom of certain insects such as bees, wasps, or hornets.
5. Food: Certain foods such as milk, eggs, wheat, and nuts can cause an allergic reaction in some people.
The symptoms of perennial allergic rhinitis are similar to those of seasonal allergic rhinitis, but they occur throughout the year rather than just during a specific season. Treatment options for perennial allergic rhinitis include over-the-counter or prescription medications such as antihistamines, decongestants, and corticosteroids, as well as immunotherapy, which involves exposing the body to small amounts of the allergen over time to build up tolerance.
Angiofibromas are usually slow-growing and may not cause any symptoms unless they become large enough to compress nearby structures or invade the surrounding tissues. They can be diagnosed by a combination of clinical examination, imaging studies such as CT or MRI scans, and histopathological analysis of a biopsy sample.
Surgical excision is the treatment of choice for angiofibromas, and the prognosis is generally good if the tumor is completely removed. However, recurrences can occur in some cases, and long-term follow-up is necessary to monitor for any signs of regrowth or malignant transformation.
Angiofibroma is a rare condition, and there is limited research available on its causes and pathophysiology. It is thought to be caused by genetic mutations that affect the development and growth of blood vessels and connective tissue in the head and neck region.
Symptoms of Bordetella Infections typically include a severe cough, fever, and difficulty breathing. In severe cases, the infection can lead to pneumonia or other complications that may require hospitalization.
Diagnosis of Bordetella Infections is usually made through laboratory tests, such as a PCR (polymerase chain reaction) test or a culture. Treatment typically involves antibiotics, which can help reduce the severity and duration of symptoms. Prevention is key, as there is no specific treatment for Bordetella Infections once they have developed. Vaccination against Bordetella pertussis is recommended for children and adults to protect against infection.
Some common types of acquired nose deformities include:
1. Nasal septal perforation: a hole or tear in the thin wall of cartilage and bone that separates the two sides of the nasal passages. This can be caused by injury, infection, or certain medical conditions.
2. Nasal polyps: growths on the lining of the nose that can block the nasal passages and affect breathing. They are often associated with allergies or asthma.
3. Enlarged turbinate bones: the turbinate bones inside the nose can become enlarged due to allergies, infection, or other factors, leading to blockage of the nasal passages and difficulty breathing.
4. Nasal trauma: injury to the nose, such as a blow to the face or a fall, can cause deformities such as a deviated septum or broken noses.
5. Skin cancer: can occur on the nose and cause deformities if left untreated.
6. Cysts and tumors: benign or malignant growths that can develop in the nose and cause deformities.
7. Nasal fractures: breaks in the bones of the nose, which can cause deformities if not properly treated.
8. Rhinophyma: a condition characterized by enlarged oil glands in the nose, leading to redness, swelling, and deformity. It is often associated with rosacea.
9. Nasal septal pterygium: a growth of tissue on the nasal septum that can cause blockage of the nasal passages and affect breathing.
10. Nasal dermoids: benign growths that occur in the skin and mucous membranes of the nose, which can cause deformities if left untreated.
The tumor typically grows slowly and may not cause any symptoms until it reaches a significant size. When symptoms do occur, they can include pain, swelling, or limited mobility in the affected area.
Hemangiopericytoma is usually diagnosed through a combination of imaging tests such as ultrasound, MRI or CT scans, and a biopsy to confirm the presence of the tumor. Treatment options for hemangiopericytoma include surgery to remove the tumor, embolization (blocking the blood supply to the tumor), or radiation therapy.
While hemangiopericytoma is generally not cancerous, it can have a high recurrence rate and may require ongoing monitoring and treatment to manage any regrowth or complications.
