Rhinosporidiosis is an infection caused by Rhinosporidium seeberi . [1] [2]
This organism was previously considered to be a fungus, and rhinosporidiosis is classified as a fungal disease under ICD-10. It is now considered to be a protist [3] classified under Mesomycetozoea. [4]
Authors of detailed studies have revealed superficial similarities between Dermocystidium and Rhinosporidium when using light microscopy, but substantial morphological differences between the groups exist. [5]
There is some evidence that DNA extracted from purified uncontaminated round bodies (Rhinosporidium seeberi) is of cyanobacterial origin. [6]
Rhinosporidiosis is a granulomatous disease affecting the mucous membrane of nasopharynx, oropharynx, conjunctiva, rectum and external genitalia. Though the floor of the nose and inferior turbinate are the most common sites, the lesions may appear elsewhere too. Traumatic inoculation from one site to others is common. Laryngeal rhinosporidiosis, [7] too, has been described and may be due to inoculation from the nose during endotracheal intubation. After inoculation, the organism replicates locally, resulting in hyperplasia of host tissue and localised immune response.[ citation needed ]
Disease endemic in Chhattisgarh South India, Sri Lanka, South America and Africa. It is presumed to be transmitted by exposure to the pathogen when taking a bath in stagnant water pools where animals also bathe.It is also common in South Asian countries.[ citation needed ]
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever.
The common cold or the cold is a viral infectious disease of the upper respiratory tract that primarily affects the respiratory mucosa of the nose, throat, sinuses, and larynx. Signs and symptoms may appear in as little as two days after exposure to the virus. These may include coughing, sore throat, runny nose, sneezing, headache, and fever. People usually recover in seven to ten days, but some symptoms may last up to three weeks. Occasionally, those with other health problems may develop pneumonia.
A pterygium of the eye is a pinkish, roughly triangular tissue growth of the conjunctiva onto the cornea of the eye. It typically starts on the cornea near the nose. It may slowly grow but rarely grows so large that it covers the pupil and impairs vision. Often both eyes are involved.
Laryngeal cancer is a kind of cancer that can develop in any part of the larynx. It is typically a squamous-cell carcinoma, reflecting its origin from the epithelium of the larynx.
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. Most infections are viral in nature, and in other instances, the cause is bacterial. URTIs can also be fungal or helminthic in origin, but these are less common.
Nasal polyps are noncancerous growths within the nose or sinuses. Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose. The growths are sac-like, movable, and nontender, though face pain may occasionally occur. They typically occur in both nostrils in those who are affected. Complications may include sinusitis and broadening of the nose.
Nocardiosis is an infectious disease affecting either the lungs or the whole body. It is due to infection by a bacterium of the genus Nocardia, most commonly Nocardia asteroides or Nocardia brasiliensis.
Rhinoscleroma, is a chronic granulomatous bacterial disease of the nose that can sometimes infect the upper respiratory tract. It most commonly affects the nasal cavity—the nose is involved in 95–100 per cent of cases—however, it can also affect the nasopharynx, larynx, trachea, and bronchi. Slightly more females than males are affected and patients are usually 10 to 30 years of age. Rhinoscleroma is considered a tropical disease and is mostly endemic to North Africa, South Asia and Central America, less common in the United States.
Rhinorrhea, also spelled rhinorrhoea or rhinorrhœa, or informally runny nose is the free discharge of a thin mucus fluid from the nose; it is a common condition. It is a common symptom of allergies or certain viral infections, such as the common cold or COVID-19. It can be a side effect of crying, exposure to cold temperatures, cocaine abuse, or drug withdrawal, such as from methadone or other opioids. Treatment for rhinorrhea may be aimed at reducing symptoms or treating underlying causes. Rhinorrhea usually resolves without intervention, but may require treatment by a doctor if symptoms last more than 10 days or if symptoms are the result of foreign bodies in the nose.
A pyogenic granuloma or lobular capillary hemangioma is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh.
Vernal keratoconjunctivitis is a recurrent, bilateral, and self-limiting type of conjunctivitis having a periodic seasonal incidence.
Rhinosporidium seeberi is a eukaryotic pathogen responsible for rhinosporidiosis, a disease which affects humans, horses, dogs, and to a lesser extent cattle, cats, foxes, and birds. It is most commonly found in tropical areas, especially India and Sri Lanka.
A pinguecula is a common type of conjunctival stromal degeneration in the eye. It appears as an elevated yellow-white plaque in the bulbar conjunctiva near the limbus. Calcification may also be seen occasionally.
Nasal septal hematoma is a condition affecting the nasal septum. It can be associated with trauma.
Lacazia is a genus of fungi containing the single species Lacazia loboi, which is responsible for Lobo's disease. It is a member of the order Onygenales.
The pharynx is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea. It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx. The flap of cartilage called the epiglottis stops food from entering the larynx.
Cat-scratch disease (CSD) is an infectious disease that most often results from a scratch or bite of a cat. Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. People may feel tired, have a headache, or a fever. Symptoms typically begin within 3–14 days following infection.
A nasopharyngeal swab is a device used for collecting a sample of nasal secretions from the back of the nose and throat. The sample is then analyzed for the presence of organisms or other clinical markers for disease. This diagnostic method is commonly used in suspected cases of whooping cough, diphtheria, influenza, and various types of diseases caused by the coronavirus family of viruses, including SARS, MERS, and COVID-19.
Nonallergic rhinitis is rhinitis—inflammation of the inner part of the nose—not caused by an allergy. Nonallergic rhinitis displays symptoms including chronic sneezing or having a congested, drippy nose, without an identified allergic reaction with allergy testing being normal. Other common terms for nonallergic rhinitis are vasomotor rhinitis and perennial rhinitis. The prevalence of nonallergic rhinitis in otolaryngology is 40%. Allergic rhinitis is more common than nonallergic rhinitis; however, both conditions have similar presentation, manifestation and treatment. Nasal itching and paroxysmal sneezing are usually associated with nonallergic rhinitis rather than allergic rhinitis. Other symptoms that are more specific to non-allergic rhinitis include ear plugging or discomfort with eustachian tube dysfunction, headaches, sinus pressure, and muffled hearing. Common triggers for non-allergic rhinitis include irritants such as tobacco smoke, cleaning agents, or abrupt changes in ambient temperature.
Tornwaldt's disease is the inflammation or abscess of the embryonic cyst of pharyngeal bursa. It is located in the midline of the posterior wall of the nasopharynx. It is covered anteriorly by mucosa in the adenoid mass. It is bounded posteriorly by longus muscle.
