Local skin flap procedure for repair of rectovaginal fistula: A case report.

Introduction: Rectovaginal fistula (RVF) is an increasingly common rectal surgery complication. Although various RVF closure operations have been reported, no one approach is considered ideal. Consequently, some patients must undergo more complex and technically challenging surgical procedures.

A modified technique for hepatic artery reconstruction in living donor liver transplantation.

Reconstruction of the hepatic artery (HA) is challenging, because there are technical difficulties. Especially, it is difficult to repair the posterior wall. In 2006, we reported an experimental study of the posterior wall first continuous suturing combined with the interrupted suturing and we also confirmed the safety of this procedure.

Three-step orbitofacial reconstruction after extended total maxillectomy using free RAM flap and expanded cervicofacial flap with cartilage grafts.

Facial defect after an extended total maxillectomy is one of the most difficult deformities to reconstruct aesthetically, because the defect is not only large but also three-dimensional. Although free-flap reconstruction is useful, the patchwork-like scar, bad colour match and poor texture match are major problems. The contracture and displacement of the reconstructed eyelids and eye socket are also serious matters.

Surgical repair of transverse facial cleft: oblique vermilion-mucosa incision.

Various surgical techniques have been reported for the repair of the transverse facial cleft using a straight-line closure, Z- or W-plasty, local flaps, etc. However, several problems remain such as deviation, distortion and scars in the commissure and cheek. To resolve these problems, we studied the anatomy of the commissure again and devised the most reasonable method for repair of the transverse facial cleft.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome following spontaneous rupture of a gouty tophus.

A 70-year-old man with a 30-year history of gout presented with a ruptured gouty tophus over the right lateral malleolus. After the debridement of the tophus, bilateral arthralgia and pitting edema were observed in his extremities. Treatments with antibiotics and nonsteroidal antiinflammatory drugs were ineffective.

The discovery of pyridalyl: a novel insecticidal agent for controlling lepidopterous pests.

Synthesis of analogues of two compounds with known insecticidal activity, both of which contain a 3,3-dichloro-2-propenyloxy group, produced 2-(trifluoromethyl)-4-phenoxyphenyl 3,3-dichloro-2-propenyl ether, which had weak activity against lepidopterous larvae. Structural modifications around this lead compound led to the development of pyridalyl [Pleo, S-1812; 2,6-dichloro-4-(3,3-dichloroallyloxy)phenyl 3-[5-(trifluoromethyl)-2-pyridyloxy]propyl ether], which belongs to a new class of insecticides. Pyridalyl gives very good control of various lepidopterous and thysanopterous pests on cotton and vegetables, without phytotoxicity.
