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 white solid that appears in form of tabular crystals. Preparation Be ... 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 caused by 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 white solid that appears in form of tabular crystals. Preparation Benzimidazole was discovered during research on vitamin B12. The benzimidazole nucleus was found to be a stable platform on which drugs could be developed. 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. 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.
