Q: "Lockjaw" is a colloquial term used to describe spasms of the masseter muscles (the jaw muscles) as a result of being infected with tetanus. Tetanus is a bacterial infection that results in painful muscle spasms; there is no cure, and 10–20% of cases result in death, which is why preventative tetanus vaccination is key.  Most people now receive the tetanus vaccine in their youth, which makes this disease quite rare. The vaccine lasts for 10 years, so after that point a booster vaccine will be needed in order to stay immune to tetanus. The tetanus infection is not passed from person to person; rather, it is contracted via a wound, usually a deep wound that can allow bacteria from the environment (usually soil) to get into the body. This is why whenever patients present to the Emergency Room with a deep wound, they are asked about the status of their tetanus vaccination. Symptoms of tetanus usually begin to appear about a week after being infected with the bacteria. In addition to the spasms of the jaw muscles (the "lockjaw" symptoms), other symptoms of tetanus can include headache, fever, sweating, restlessness, trouble swallowing, irritability, and strange-looking facial expressions due to the muscle stiffness and spasms. Ideally, you will have seen a doctor right when you were first potentially exposed to the tetanus bacteria. If you have not been immunized within the past 10 years, they will inject you with tetanus immune globulin followed by the vaccine.  3,000 to 6,000 units of tetanus immune globulin drug is administered via intramuscular shots. This injectable solution contains Immunoglobulin G, an antibody that helps your body get rid of all the toxins produced by the tetanus causing bacteria. Administration of this treatment will boost your immunity, helping you fight the infection. A local anesthetic can be added to the injection to lower the amount of pain. Administration of this drug must always be done under medical supervision. The doctors will also clean your wound thoroughly, and remove any foreign material that may be present in the wound, to minimize the chances of a tetanus infection.  Note that if you are already presenting with symptoms of "lockjaw," this means that you are late in seeking treatment; however, the doctors will give you the injection anyway even though it is preferable to have gotten it earlier (it can still be somewhat effective later on). If you have a tetanus infection, home treatment is not an option, and medications will be administered in the hospital. Muscle relaxers, such as Carisoprodol, and sedatives are commonly used to help relieve muscle spasms in your jaw and elsewhere on your body.  Neuromuscular blocking agents are also useful in treating spasms. These medications include pancuronium, vecuronium, and baclofen.  Your breathing and heartbeat can be affected by muscle spasms as well as by the use of sedatives. You may need to use a ventilator while in the hospital. In severe causes, you may be taken to the ICU, These facilities are ideal in severe cases because close monitoring of vital functions such as breathing and your heart rate can occur continuously, until you hopefully recover.
A: Understand what lockjaw is. Seek rapid medical attention. Try medications.

Q: Thread your needle with matching, lightweight thread, and sew straight across your hem roughly 1/4 inch (6 mm) away from the raw edge.  After sewing this line, trim the edge so that there is only 1/8 inch (3 mm) between the thread line and the raw edge. This stitch will end up being on the bottom of your hem. It should help you maintain an even, consistent roll. Fold the raw edge toward the wrong side of the fabric and press in place using an iron.  While not entirely necessary, pressing the fold in place will make the hem less likely to unroll as you stitch. Fold the fabric so that the bend falls just past your initial row of stitching. You should see your initial stitching along the underside of the fabric but not from the front. Pick up one thread from the fabric and a small stitch from the edge of your fold. Pull the needle through, but do not pull it taut just yet.  Use a small, sharp needle for best results. Doing so will make it easier to pick up single threads along your hem. The stitch made into your fold should be as close to the actual fold as possible. Position it in between your initial line of stitching and the fold itself. The threads you pick up from the front of the actual fabric should be directly above the stitch made into your fold. These threads should also be right above the raw edge. Make sure that you only pick up one or two threads from the fabric. Picking up more will cause the hem to be more visible from the front of the fabric. Each stitch should only pick up one or two threads from the fabric, and the stitches should be spaced roughly 1/4 inch (6 mm) apart. Repeat this until you have 1 to 2 inches (2.5 to 5 cm) of hem stitching. Lightly pull on the thread in the direction of your stitching. The raw edge should roll itself down into your hem, disappearing from sight.  Use firm pressure, but do not pull tightly. Pulling too tightly can cause the fabric to bunch up. Smooth out any bubbles or bumps with your fingers. Continue stitching along the rest of the hem in the same manner until you reach the end. Knot off the end and cut off any excess thread.  As you get better at the process, you can pull the thread after 4 to 5 inches (10 to 13 cm) of stitching rather than every 1 to 2 inches (2.5 to 5 cm). If completed correctly, the raw edge should be hidden along the wrong side of the fabric and the hem stitching should be barely visible from the front. The hem may already be smooth enough, but if desired, use an iron to press it further. This step completes the process.
A:
Sew straight across the raw edge. Fold in the raw edge. Pick up a few threads with your sewing needle. Make a few more stitches in the same manner. Pull the thread through. Repeat along the length of the hem. Iron press when finished.
