The trypan blue-stained viscoelastic is removed in its entirety using a Simcoe cannula. A stream of Healonid GV can be seen flowing into the cannula with some residual viscoelastic remaning, which is subsequently removed. Without the dye, much of the viscoelastic might have been left in the anterior... chamber – a risk factor for an acute rise in intra ocular pressure.

Bunion Hallux Abductor Valgus Surgery

A "Hallux Valgus" or "Hallux Abducto-Valgus" deformity, is commonly referred to as a "Bunion." This describes a pathological condition involving the position of the "hallux" in relation to the first metatarsal.

A bunion deformity can clinically present with a variety of characteristics. The foot itself may present with a wide splaying of the forefoot and a painful bump on the medial aspect of the first metatarsal phalangeal joint. In addition, the hallux may be abducted from the midline of the body, with a valgus rotation in the frontal plane.

A radiographic analysis of a bunion deformity in the Anterior/Posterior or Dorsal/Plantar view will reveal a variety of pathological components. Most notably so, is the exaggerated inter-metatarsal angle between the first and second metatarsal. This may be accompanied by a displacement of the first metatarsal from its position over the sesamoids, such that the metatarsal demonstrates a medial alignment away from the sesamoids which lie to the lateral side.

In some cases, the proximal articular set angle at the head of the first metatarsal may be off-set. This "PASA" is one of the factors which determines the position of the proximal phalanx on the metatarsal during movement as well as at rest.

Although conservative care may involve shoe modifications, padding, strapping, and custom orthosis; surgical reconstruction may be required to alleviate painful and immobilizing bunion conditions.

Soft tissue components of the bunion deformity are primarily addressed by means of a capsular modification, as well as a tenotomy of the adductor tendon at its insertion on the base of the proximal phalanx. The fibular sesamoid may be repositioned by a release of the surrounding ligaments.

Surgical management of the bone or osseous components of a bunion deformity will commonly include an osteotomy and correction to re-establish a more functional position of the first metatarsal within the forefoot. This capital fragment of bone is held in place with hardware fixation in order to secure a proper alignment during the healing phase, thus allowing the hallux to return to a more functionally useful position in the sagittal plane.

Mechanism of Cisplatin Anti-Cancer Drug
Mechanism of Cisplatin Anti-Cancer Drug Scott Stevens 16,931 Views • 2 years ago

Cisplatin is in a class of drugs known as platinum-containing compounds used to treat various types of cancers including metastatic testicular and ovarian tumors. The molecule was first discovered in 1845, but did not receive FDA approval until 1978. Today it is known as the "penicillin of cancer drugs," because it is so effective for many different cancers. There are three key players involved in Cisplatin's mechanism: (1) Cisplatin, (2) DNA (3) and an HMG Protein. Most Cisplatin enters the body through active transport, but some molecules are passively defused through the cell membrane. Once in the nucleus, Cisplatin can form an adduct with two consecutive guanine bases within a strand of DNA. The molecule loses its chlorine atoms in exchange for the nitrogen atoms of the target guanines. Cisplatin can bond more tightly with nitrogen because nitrogen balances the platinum charge more effectively than chlorine. It is this adduct-induced DNA bend that allows binding of proteins which contain the high mobility group, HMG domain. Once the protein is bound to the DNA, it inserts a wedge-like phenyl group of phenylalanine 37 into the widened minor groove created by the bend. The tightly bound HMG protein causes destacking of the nucleotide bases, resulting in the DNA helix becoming kinked. In this way, Cisplatin can be thought of as a monkey wrench in the DNA repair system. With the HMG protein bound to the DNA, the modified strand is not repaired properly and so the cell dies. The success of Cisplatin depends on its ratio of efficacy between cancerous and healthy cells.
