What is Herpes Zoster Oticus ( Ramsey Hunt Syndrome)

Ramsay Hunt syndrome is regarded as an acute peripheral facial neuropathy linked with the erythematous vesicular rash of the skin of the ear canal, mucous membrane of the oropharynx. And auricle (also termed herpes zoster oticus). This syndrome is also understood as geniculate neuralgia or nervus intermedius neuralgia. Ramsay Hunt syndrome can also happen in the absence of a skin rash, a condition known as zoster sine herpete. Ramsay Hunt…

Xerostomia (Dry Mouth)

Xerostomia also is known as Dry Mouth is caused by lower levels or the absence salivation within the mouth. This condition can often lead to discomfort which negatively affects your ability speak, swallowing, an ability to wear dentures, producing bad breath and compromise your oral hygiene due to reducing the oral pH and an increase in bacterial growth. Persistent xerostomia can lead to severe tooth decay and oral candidiasis. Xerostomia…

Understanding Bruton’s Disease ( X-Linked Agammaglobulinemia)

(Bruton’s disease) The X-linked agammaglobulinemia is characterized by low or absent immunoglobulin levels and lack of B cells, leading to recurrent infections with encapsulated bacteria. (See also Overview of immune deficiency disorders, and approach to the patient with an immunodeficiency disorder.) The X-linked agammaglobulinemia is characterized by low or absent immunoglobulin levels and lack of B cells, leading to recurrent infections with encapsulated bacteria. Agammaglobulinemia is a primary immunodeficiency disease…

X-Linked Lymphoproliferative Syndrome Inherited

(Duncan’s syndrome) The X-linked lymphoproliferative syndrome is a result of a defect in the T-cells and natural killer cells and is characterized by an abnormal sensitivity to Epstein-Barr virus infections. This can lead to liver failure, immunodeficiency, lymphoma, fatal lymphoproliferative diseases or bone marrow aplasia. (See also Overview of immune deficiency disorders, and approach to the patient with an immunodeficiency disorder.) The X-linked lymphoproliferative syndrome is a result of a…

X-Ray And Other Imaging Contrast Examinations

The main contraindication in X-ray contrast media studies is a suspicion of a perforation because free barium causes severe irritation to the mediastinum or peritoneum; water-soluble contrast agents are less irritating and can be used in cases of possible perforation. In elderly patients, storage and rotation for optimum positioning of barium and intraluminal air often causes difficulties. X-ray and other imaging contrast examinations are the entire GIT from the pharynx…

X-Ray Contrast Media And Contrast Media Reactions

Iodinated contrast agents may be Radiopaque contrast agents are often used in radiography and fluoroscopy, to distinguish boundaries between tissues of similar X-ray density. Most contrast agents containing iodine. Iodinated contrast agents may be Ionic Nonionic Ionic contrast media, the salts are hyperosmolar as compared to blood. Ionic contrast agent should be used either for myelographic investigations, nor for injections in which it into the spinal canal (neurotoxic risk side…

What Is Yellow Fever?

The yellow fever virus, a flavivirus, is transmitted by mosquitoes and is endemic in tropical South America and sub-Saharan Africa. The symptoms can consist of sudden fever onset, relative bradycardia, headache and, in severe cases, jaundice, hemorrhages and multiple organ failure. The diagnosis is made by a virus cell culture, reverse transcription and serological tests. Treatment is supportive. For prevention are vaccination and control of mosquitoes available. (See also Overview…

What is Zap-70 Deficiency?

The ZAP-70 (zeta-associated protein 70) deficiency is characterized by an impaired T-cell activation, which is caused by a malfunction of signal transduction. ZAP-70 deficiency is a primary immunodeficiency disease which includes cellular immune deficiencies. Inheritance occurs as an autosomal recessive. The ZAP-70 protein plays an essential role in T-cell signaling and T cell selection in the thymus. A ZAP-70 deficiency leads to defects in T cell activation. Patients with ZAP-70…

Wheezing: Causes and Treatment

Wheezing is a relatively high-pitched whistling sound, which is generated by the movement of air through constricted or compressed small airways. It is both a symptom and auscultation, Longer expiratory phase wheezing. The air flow through a constricted or compressed segment of small airway becomes turbulent, resulting in vibrations of the airway walls. This vibration generates the sound of wheezing. Wheezing occurs more frequently during expiration because of increased intrathoracic…

What are Cervical myomas

Cervical myomas is well-circumscribed, benign tumors of the cervix. Cervical myomas are well-circumscribed, benign tumors of the cervix. Cervical myomas are rare. Uterine fibroids (myomas Fibroids- of the uterus) are usually present simultaneously. Large Cervical myomas can relocate or urinary tract partially prolapse into the vagina. Prolapsed fibroids can form or developed from these types ulcers, infections, bleeding or a combination. Symptoms and signs Most Cervical myomas can trigger symptoms…
