When I was a general surgery resident, we had a couple of patients come in with maggots in their wounds--both with venous stasis ulcers on their legs. As "icky" as it was to clean the maggots out of the wounds, it was down right impressive how clean the wounds were (and yes it was my job to do the cleaning). Those maggots sure had done a wonderful job of removing the necrotic tissue and leaving behind healthy granulation tissue. (photo credit) So for Halloween, how about some bug therapy.
Maggot therapy waxes and wanes in popularity throughout time. Ambroise Pare (1509-1590) is generally given credit for first noting the beneficial effects of maggots in suppurative wounds. Napoleon's famous military surgeon, Baron D. J. Larrey (1766-1842) noted larvae of the blue fly in the wounds of soldiers in Syria during the Egyptian expedition. He noted that the maggots only attacked putrefying substances rather than living tissues and that they promoted their cicatrization. W. W. Keen commented on the presence of maggots in wounds during the Civil War, saying that the maggots were disgusting but did no apparent harm. The first scientific study of the use of maggots was done by Dr. William S. Baer of Baltimore, Maryland. He first mentioned this "viable antiseptic" for the treatment of chronic osteomyelitis in a discussion following an article by Bitting that appeared in 1921. Baer commented on the clean wound of two soldiers with neglected compound femur fractures and abdominal wounds who had lain neglected for 7 days on the battlefields of World War I in 1917. Inspection of the wounds showed that they were infected with thousands of maggots, but had healthy granulation tissue beneath. At that time, the mortality from such wounds with the best medical care was close to 75%, and therefore the maggots made a profound impression. He went on to study maggots in detail.
Maggots, by definition, are fly larvae, just as caterpillars are butterfly or moth larvae. Phaenicia sericata (green blow fly) larvae is the one used in maggot therapy.
A drawing of the life cycle of this fly appears below. (photo credit)
One-day-old larvae are only about 2 mm in length, and almost transparent. By the time the maggots are 3 or 4 days old, they have grown to about 1 cm (1/2 inch) long. (photo credit)
Maggots may be used intentionally as biological debriding agents. They are an effective alternative to surgical debridement in patients who cannot go to the operating room for medical reasons. It is the larvae of the green blowfly (Phaenicia sericata) that is used. This larvae is sterilized with radiation before being used so that they will not be able to convert from the larvae to the pupae stage. They secrete enzymes that dissolve the necrotic tissue and the biofilm that surrounds bacteria. This forms a nutrient-rich liquid that larvae can feed on. Thirty larvae can consume 1 gram of tissue per day. They are placed on wounds and covered with a semipermeable dressing. The debridement is painless, but the sensate patient can feel the larvae moving. More importantly, maggots help to sterilize wounds, because they consume all bacteria regardless of their resistance to antibiotics (including methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus). Maggots have to be replaced every 2 to 3 days. Maggot therapy can be administered on an outpatient basis, provided that visiting nurses are familiar with their use. This is a good technique for painlessly removing necrotic tissue and destroying antibiotic-resistant bacteria in patients who cannot undergo surgical debridement for medical reasons. They work well in infected and gangrenous wounds, with the best results reported in diabetic wounds.
Medical grade larvae are available from Zoobiotic Ltd and Monarch Labs.

As increasing numbers of valves fail under the strain, high pressure is communicated into a widening network of dilated superficial veins in a recruitment phenomenon. Over time, large numbers of incompetent superficial veins acquire the typical dilated and tortuous appearance of varicosities. " (

postoperatively. It occurs in 1-2% of patients who have a sternotomy. Most of these patients are cardiac surgery patients (more than 300,000 cases per year in the US). Most of these are coronary bypass patients rather than heart valve or transplant patients. Some other causes of mediastinitis, other than postoperative, include 1) esophageal perforation; 2) trauma, especially blunt trauma to the chest or abdomen; 3) tracheobronchial perforation, due to either penetrating or blunt trauma or instrumentation during bronchoscopy; 4) descending infection following surgery of the head and neck, great vessels, or vertebrae; 5) progressive odontogenic infection (Ludwig angina); 6) mediastinal extension of lung infection; and 7) chronic fibrosing mediastinitis due to granulomatous infections.

ars clean with adequate granulation tissue. At this point, muscle flap closure is achieved. The workhorse flap is the unipedicled pectoralis major muscle flap. It is based on its primary blood supply from the acromioclavicular axis. By detaching the muscle from its sternal, rib, humeral, and medial clavicular attachments and separating it from the clavicular head of the deltoid, it can usually be extended to the level of the xiphoid. Back cutting the superior medial segment of the pectoralis muscle for a distance of 4 to 6 cm maintains its blood supply and permits it to be tucked into an upper manubrial dead space. Distal closure at the level of or below the xiphoid is accomplished by approximating the upper medial ends of the rectus sheath with large no. 1 sutures. (

lginate which is a seaweed component. When the dressing is in contact with wound, the calcium in the dressing is exchanged with sodium from the wound fluid and this turns dressing into a gel that maintains a moist wound environment. It is a good dressing for exudating wounds and helps in debridement of sloughing wounds. It should not be used on low exudating wounds as this will cause dryness and scabbing. This dressing should be changed daily. (

ing one incorrectly can leave you with cut fingers. Minor cuts will often stop bleeding on their own or by applying direct pressure to the wound. Most of these cuts and scraps will be minor and can be treated by washing with soap and water initially. Then keep the wound clean and dry while it heals. However, if the bleeding continues after 15 minutes or if you lose the ability to move the finger properly (very likely a tendon injury), then seek medical attention at a hospital emergency department.
