PAIR (puncture-aspiration-injection-reaspiration)
The PAIR (''puncture-aspiration-injection-reaspiration''; sometimes ''percutaneous aspiration-injection-reaspiration'') procedure is a noninvasive treatment option to remove hydatid cysts. PAIR is considered an alternative treatment for cystic echinococcosis (hydatid disease) and is often indicated for patients who do not respond to surgery or benzimidazoles Benzimidazole is a heterocyclic aromatic organic compound. This bicyclic compound may be viewed as fused rings of the aromatic compounds benzene and imidazole. It is a colorless solid. Preparation Benzimidazole is produced by condensation of o ... The PAIR procedure can be performed as follows: # ultrasound-guided percutaneous puncture of the cyst # aspiration of cystic fluid # injection of a scolicidal solution # reaspiration of the solution References {{Reflist Medical procedures ...

Echinococcosis
Echinococcosis is a parasitic disease of tapeworms of the ''Echinococcus'' type. The two main types of the disease are ''cystic echinococcosis'' and '' alveolar echinococcosis''. Less common forms include ''polycystic echinococcosis'' and ''unicystic echinococcosis''. The disease often starts without symptoms and this may last for years. The symptoms and signs that occur depend on the cyst's location and size. ''Alveolar'' disease usually begins in the liver, but can spread to other parts of the body, such as the lungs or brain. When the liver is affected, the patient may experience abdominal pain, weight loss, along with yellow-toned skin discoloration from developed jaundice. Lung disease may cause pain in the chest, shortness of breath, and coughing. The infection is spread when food or water that contains the eggs of the parasite is ingested or by close contact with an infected animal. The eggs are released in the stool of meat-eating animals that are infected by the para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydatid Disease
Hydatid may refer to: * Echinococcosis * ''Echinococcus granulosus'', known as the hydatid tapeworm * Hydatid of Morgagni * Hydatidiform mole A molar pregnancy also known as a hydatidiform mole, is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus.

Benzimidazoles
Benzimidazole is a heterocyclic aromatic organic compound. This bicyclic compound may be viewed as fused rings of the aromatic compounds benzene and imidazole. It is a colorless solid. Preparation Benzimidazole is produced by condensation of o-phenylenediamine with formic acid,. or the equivalent trimethyl orthoformate: :C6H4(NH2)2 + HC(OCH3)3 → C6H4N(NH)CH + 3 CH3OH 2-substituted derivatives are obtained when the condensation is conducted with aldehydes in place of formic acid, followed by oxidation.Robert A. Smiley "Phenylene- and Toluenediamines" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. Reactions Benzimidazole is a base: :C6H4N(NH)CH + H+ → 6H4(NH)2CHsup>+ It can also be deprotonated with stronger bases: :C6H4N(NH)CH + LiH → Li 6H4N2CH + H2 The imine can be alkylated and also serves as a ligand in coordination chemistry. The most prominent benzimidazole complex features ''N''-ribosyl-dimethylbenzimidazole as found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
