Methods are taught for treating chronic wounds and skin and soft tissue infections with antibiotic tumescent injection. In such methods, the region of tumescent drug delivery is monitored and expanded by the infusate in order to be 2&#xd7;-5&#xd7; larger in area and volume in the region of the wound or infection, the drug in the infusate creates a tissue concentration greater than the MIC in the tumescent volume for selected period of time, and the high concentration has a residence lifetime in the tissue long enough to kill the bacteria. Typically, the methods are performed without the use of vasoconstrictors such as epinephrine and in a manner that avoids physical manipulation of the wound.

An optical transceiver that reduces the EMI noise leaked therefrom is disclosed. The optical transceiver provides a metal housing, an optical subassembly, and an electronic circuit. The metal housing includes a first space to install the electronic circuit, and a second space to install the optical subassembly. At least the first space has inner surfaces having a corrugated shape to reduce the resonance of the electromagnetic waves.

An optical transceiver that reduces the EMI noise leaked therefrom is reduced is disclosed. The optical transceiver of the invention provides a metal housing, an optical subassembly, and an electronic circuit. The metal housing includes a first space that installs the electronic circuit and a second space that installs the optical subassembly. The first space and the second space are electrically shielded to each other, in addition that both spaces are shielded from the external. In the optical transceiver of the invention, even the second space provides the optical path to the optical connector, which becomes a definite leak path for the EMI noise, the leakage from the first space to the external through the optical path is prevented.
