Continuous wound infiltration-Continuous wound infiltration-Continuous wound infiltration (CWI) refers to the continuous infiltration of a local anesthetic into a surgical wound to aid in pain management during post-operative recovery. | milkshake721/2.1M-wiki-STEM |
Continuous wound infiltration-History-Continuous wound infiltration first appeared on the market in the late 1990s when a US company (I-Flow Corporation) found a way to evenly spread and continuously infiltrate a local anesthetic, via a specially designed multi holed catheter, inside the wound, to enable post-operative... | milkshake721/2.1M-wiki-STEM |
Continuous wound infiltration-Technique-A local anesthetic is administered into the wound with a specially designed, multi-holed catheter. The catheter allows for even spread throughout the entire area of the wound, depending on the size of the catheter. | milkshake721/2.1M-wiki-STEM |
Continuous wound infiltration-Technique-The surgeon places the catheter during surgery shortly before closing the surgical incision. For best catheter placement and nerve blockage, the catheter must be located as close as possible to the nerve. Tunneling should be applied if a distal infiltration of the adjacent nerve ... | milkshake721/2.1M-wiki-STEM |
Continuous wound infiltration-Outcomes-CWI is considered as an effective alternative to other regional anesthetic techniques such as peripheral nerve blocks and spinal-epidural anesthesia. It is especially applicable where those techniques are contra-indicated, such as in patients using potent coagulants. | milkshake721/2.1M-wiki-STEM |
Continuous wound infiltration-Outcomes-Besides, some patients might prefer an alternative to epidural analgesia because of epidural-related side effects.

Morsicatio buccarum-Morsicatio buccarum-Morsicatio buccarum is a condition characterized by chronic irritation or injury to the buccal mucosa (the lining of the inside of the cheek within the mouth), caused by repetitive chewing, biting or nibbling. | milkshake721/2.1M-wiki-STEM |
Morsicatio buccarum-Signs and symptoms-The lesions are located on the mucosa, usually bilaterally in the central part of the anterior buccal mucosa and along the level of the occlusal plane (the level at which the upper and lower teeth meet). Sometimes the tongue or the labial mucosa (the inside lining of the lips) is ... | milkshake721/2.1M-wiki-STEM |
Morsicatio buccarum-Causes-The cause is chronic parafunctional activity of the masticatory system, which produces frictional, crushing and incisive damage to the mucosal surface and over time the characteristic lesions develop.

Morsicatio buccarum-Diagnosis-The diagnosis is usually made on the clinical appearance alone, and biopsy is not usually indicated.

Xargs-Xargs-xargs (short for "extended arguments" ) is a command on Unix and most Unix-like operating systems used to build and execute commands from standard input. It converts input from standard input into arguments to a command.
Some commands such as grep and awk can take input either as command-line arguments or f... | milkshake721/2.1M-wiki-STEM |
Xargs-Examples-One use case of the xargs command is to remove a list of files using the rm command. POSIX systems have an ARG_MAX for the maximum total length of the command line, so the command may fail with an error message of "Argument list too long" (meaning that the exec system call's limit on the length of a comm... | milkshake721/2.1M-wiki-STEM |
Xargs-Examples-Some implementations of xargs can also be used to parallelize operations with the -P maxprocs argument to specify how many parallel processes should be used to execute the commands over the input argument lists. However, the output streams may not be synchronized. This can be overcome by using an --outpu... | milkshake721/2.1M-wiki-STEM |
Xargs-Examples-xargs often covers the same functionality as the command substitution feature of many shells, denoted by the backquote notation (`...` or $(...)). xargs is also a good companion for commands that output long lists of files such as find, locate and grep, but only if one uses -0 (or equivalently --null), s... | milkshake721/2.1M-wiki-STEM |
Xargs-Placement of arguments--I option: single argument The xargs command offers options to insert the listed arguments at some position other than the end of the command line. The -I option to xargs takes a string that will be replaced with the supplied input before the command is executed. A common choice is %.
The s... | milkshake721/2.1M-wiki-STEM |
Xargs-Placement of arguments-Shell trick: any number Another way to achieve a similar effect is to use a shell as the launched command, and deal with the complexity in that shell, for example: The word sh at the end of the line is for the POSIX shell sh -c to fill in for $0, the "executable name" part of the positional... | milkshake721/2.1M-wiki-STEM |
Xargs-Placement of arguments-Since cp accepts multiple files at once, one can also simply do the following: This script runs cp with all the files given to it when there are any arguments passed. Doing so is more efficient since only one invocation of cp is done for each invocation of sh. | milkshake721/2.1M-wiki-STEM |
Xargs-Separator problem-Many Unix utilities are line-oriented. These may work with xargs as long as the lines do not contain ', ", or a space. Some of the Unix utilities can use NUL as record separator (e.g. Perl (requires -0 and \0 instead of \n), locate (requires using -0), find (requires using -print0), grep (requir... | milkshake721/2.1M-wiki-STEM |
Xargs-Separator problem-But often people forget this and assume xargs is also line-oriented, which is not the case (per default xargs separates on newlines and blanks within lines, substrings with blanks must be single- or double-quoted).
The separator problem is illustrated here: Running the above will cause important... | milkshake721/2.1M-wiki-STEM |
Xargs-Separator problem-The proper fix is to use the GNU-specific -print0 option, but tail (and other tools) do not support NUL-terminated strings: When using the -print0 option, entries are separated by a null character instead of an end-of-line. This is equivalent to the more verbose command:find . -name not\* | tr \... | milkshake721/2.1M-wiki-STEM |
Xargs-Separator problem-GNU parallel is an alternative to xargs that is designed to have the same options, but is line-oriented. Thus, using GNU Parallel instead, the above would work as expected.For Unix environments where xargs does not support the -0 nor the -d option (e.g. Solaris, AIX), the POSIX standard states t... | milkshake721/2.1M-wiki-STEM |
Xargs-Operating on a subset of arguments at a time-One might be dealing with commands that can only accept one or maybe two arguments at a time. For example, the diff command operates on two files at a time. The -n option to xargs specifies how many arguments at a time to supply to the given command. The command will b... | milkshake721/2.1M-wiki-STEM |
Xargs-Encoding problem-The argument separator processing of xargs is not the only problem with using the xargs program in its default mode. Most Unix tools which are often used to manipulate filenames (for example sed, basename, sort, etc.) are text processing tools. However, Unix path names are not really text. Consid... | milkshake721/2.1M-wiki-STEM |
Xargs-Encoding problem-One workaround for this problem is to run such tools in the C locale, which essentially processes the bytes of the input as-is. However, this will change the behavior of the tools in ways the user may not expect (for example, some of the user's expectations about case-folding behavior may not be ... | milkshake721/2.1M-wiki-STEM |
