When choosing a site for plantation establishment, it is typically good practice to ensure it exhibits good drainage and is non shaded. It should not be next to old Scotch pine stands, which could still hold the "Cyclaneusma". The trees in the plantation should have adequate spacing to allow for proper air circulation. Additionally, the owner should invest in tree stock which displays resistance or tolerance to "Cyclaneusma." After planting, attentive tree care must be undertaken, including nutrient management and water and weed control, to ensure robust, healthy trees. To scout for the disease, the threshold level is 20% of sampled trees showing signs. At this point, the owner should consider treating the entire plantation. In some areas, it is possible to control the disease through the silvicultural practice of thinning, selecting for trees with resistance to "Cyclaneusma".

"Cyclaneusma" presents somewhat of a challenge to manage, as infected needles remain part of the tree throughout the winter and spring months. The creation of spores as well as infection can occur in freezing temperatures with wet needles. Inoculated needles may not develop symptoms for up to a year from the infection date, proving difficult for the effectiveness of pesticides applied in the first season to be judged. Infected needles on or under the tree retain the ability to release spores any time during the growing season, so they should be removed as soon as possible. It is typically recommended to apply five treatments of fungicide, such as chlorothalonil or dodine, when the threshold level is met, beginning in March and continuing roughly every 5–6 weeks through October. If the infection level of a Christmas tree plantation is not yet too high, the aesthetics of the tree can be saved by using a leaf blower to remove infected needles from the tree.

"Cyclaneusma" is favored by wet, humid, above freezing conditions. This provides adequate conditions for "Cyclaneusma" to thrive in the given environment. A study analyzing "Cyclaneusma" on "Pinus radiata" determined that continuous climate change (global warming) would favor the infection of pines by "Cyclaneusma" because much more of the environment would consist of moderately warm, wet, and humid conditions. Additionally, higher altitude elevations favor "Cyclaneusma" due to the wetter environment.

The high demand for pine trees during the holiday month of December can contribute to the success of "Cyclaneusma". The clustering of pines in a limited area of land enable the disease to spread its ascospores over short distances but through high concentrations of susceptible hosts and therefore poses a problem for Christmas tree production companies. "Cyclaneusma" does not appear to be affected by insect vectors.

An escharotic is a substance that causes tissue to die and slough off. Examples include acids, alkalis, carbon dioxide, metallic salts and sanguinarine, as well as certain medicines like imiquimod. Escharotics known as black salves, containing ingredients such as zinc chloride and sanguinarine containing bloodroot extracts, were traditionally used in herbal medicine as topical treatments for localised skin cancers, but often cause scarring and can potentially cause serious injury and disfigurement. Consequently, escharotic salves are very strictly regulated in most western countries and while some prescription medicines are available with this effect, unauthorized sales are illegal. Some prosecutions have been pursued over unlicensed sales of escharotic products such as Cansema.

An eschar (; Greek: "eschara") is a slough or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, spotted fevers and exposure to cutaneous anthrax. The term "eschar" is not interchangeable with "scab". An eschar contains necrotic tissue, whereas a scab is composed of dried blood and exudate.

Black eschars are most commonly attributed to anthrax, which may be contracted through herd animal exposure, but can also be obtained from "Pasteurella multocida" exposure in cats and rabbits. A newly identified human rickettsial infection, "R. parkeri" rickettsiosis, can be differentiated from Rocky Mountain spotted fever by the presence of an eschar at the site of inoculation.

Eschar is sometimes called a "black wound" because the wound is covered with thick, dry, black necrotic tissue.

Eschar may be allowed to slough off naturally, or it may require surgical removal (debridement) to prevent infection, especially in immunocompromised patients (e.g. if a skin graft is to be conducted).

If eschar is on a limb, it is important to assess peripheral pulses of the affected limb to make sure blood and lymphatic circulation is not compromised. If circulation is compromised, an escharotomy, or surgical incision through the eschar, may be indicated.

In 1977, a disease of scleractinian corals appeared on reefs off the Florida Keys in the United States and was termed white plague. It caused white lesions and was shown to be an infectious disease, being particularly prevalent in "Mycetophyllia ferox". This disease caused little mortality and occurred sporadically, but was still present in the area in 1984. It is now known as white plague type 1.

In 1995, a new coral disease was described as an epizootic disease in the same reefs in the Florida Keys. Many species of coral found in the area were affected and the mortality rate of these was up to 38%. The pathogen involved was found to be a previously unknown species of bacterium in the order Rhizobiales, which was placed in the newly created genus "Aurantimonas" and given the name "Aurantimonas coralicida", and the disease was described as white plague type 2. The pathogen was isolated from a diseased colony of "Dichocoenia stokesi" and cultured in the laboratory, subsequently being used to inoculate two healthy colonies which then developed the disease. In the next few months, it had spread over of reef and was killing seventeen species of coral. Over the next four years, it spread further, but interestingly, was most severe in different regions each year.

However, white plague is an enigmatic disease. Further research cast into doubt the role of "A. coralicida" as a causative agent by finding that bacterium on healthy parts of colonies of "Orbicella annularis" affected by white plague disease but absent from diseased parts. In these diseased colonies, an α-proteobacterium similar to one which causes a disease in juvenile oysters has been implicated, being found on the diseased parts of the coral but not on the sound tissues. These anomalous findings may be caused by the fact that there are two or more diseases with similar symptoms, both known as white plague.

In 1999, a third and still more virulent variant appeared in the northern Florida Keys. White plague type III mostly affected "Colpophyllia natans" and "Orbicella annularis".

A white-plague like disease reported from the Red Sea in 2005 has been shown to be caused by a different bacterial pathogen, "Thalassomonas loyana". Further research has shown that viruses may be involved in white plague infections, the coral small circular ssDNA viruses (SCSDVs) being present in association with diseased tissue. This group of viruses is known to cause disease in plants and animals.

As first described by Dunstan in 1977, white plague type 1 produces lesions on any part of the colony. These increase gradually in size, advancing at the rate of a few millimetres per day. The advancing edge exhibits a sharp boundary between the apparently healthy tissue and the bare skeleton. Type II, first appearing in 1995 is similar, but it usually starts at the base of the colony, and the edge advances at a faster rate, up to per day. White plague type III advances at a rate in excess of two centimetres per day.

Several alternate therapies such as vitamin E treatment, have been studied, although without control groups. Most doctors do not value those treatments. None of these treatments stops or cures the condition permanently.

Laser treatment (using red and infrared at low power) was informally discussed in 2013 at an International Dupuytren Society forum, as of which time little or no formal evaluation of the techniques had been completed.

Only anecdotal evidence supports other compounds such as vitamin E.

Radiation therapy has been used mostly for early stage disease, but is unproven. Evidence to support its use as of 2017, however, is poor; efforts to gather evidence are complicated due to a poor understanding of the how the condition develops over time. It has only been looked at in early disease.

Soot tattoos are considered the oldest form of tattoos. The 5300 year old body of Tyrolean iceman Ötzi is decorated with simple tattoos, and researchers think they may have served a medicinal purpose, not a decorative one.

Soot tattoos are still used in some countries.

Follow standard precautions to help prevent the spread of bloodborne pathogens and other diseases whenever there is a risk of exposure to blood or other bodily fluids. Standard precautions include maintaining personal hygiene and using personal protective equipment (PPE), engineering controls, and work practice controls among others. Always avoid contact with blood and other bodily fluids. Wear disposable gloves when providing care, particularly if you may come into contact with blood or bodily fluids. Dispose properly of gloves and change gloves when providing care to a new patient. Use needles with safety devices to help prevent needlestick injury and exposure to bloodborne pathogens.

A hierarchy of controls can help to prevent environmental and occupational exposures and subsequent diseases. These include:

Elimination: Physically remove hazards, including needles that lack a safety device. Additionally, eliminate the use of needle devices whenever safe and effective alternatives are available.

Substitution: Replace needles without safety devices with ones that have a safety feature built in. This has been shown to reduce bloodborne diseases transmitted via needlestick injuries.

Engineering controls: Isolate people from the hazard by providing sharps containers for workers to immediately place needles in after use.

Administrative controls: Change the way people work by creating a culture of safety such as avoiding recapping or bending needles that may be contaminated and promptly disposing of used needle devices and other sharps.

Personal protective equipment: Protect workers with PPE such as gloves and masks to avoid transmission of blood and other bodily fluids.

Soot tattoos are a cutaneous condition that may be a sign of drug abuse, a condition produced by injections of residual carbon on the needle after flaming of the tip.

Blood for blood transfusion is screened for many bloodborne diseases. Additionally, a technique that uses a combination of riboflavin and UV light to inhibit the replication of these pathogens by altering their nucleic acids can be used to treat blood components prior to their transfusion, and can reduce the risk of disease transmission.

A technology using the synthetic psoralen, amotosalen HCl, and UVA light (320–400 nm) has been implemented in European blood centers for the treatment of platelet and plasma components to prevent transmission of bloodborne diseases caused by bacteria, viruses and protozoa.

Treatment usually involves resting the affected foot, taking pain relievers and trying to avoid putting pressure on the foot. In acute cases, the patient is often fitted with a cast that stops below the knee. The cast is usually worn for 6 to 8 weeks. After the cast is taken off, some patients are prescribed arch support for about 6 months. Also, moderate exercise is often beneficial, and physical therapy may help as well.

Prognosis for children with this disease is very good. It may persist for some time, but most cases are resolved within two years of the initial diagnosis. Although in most cases no permanent damage is done, some will have lasting damage to the foot. Also, later in life, Kohler's disease can spread to the hips.

After exposure to the hepatitis B virus (HBV), appropriate and timely prophylaxis can prevent infection and subsequent development of chronic infection or liver disease. The mainstay of PEP is the hepatitis B vaccine; in certain circumstances, hepatitis B immunoglobulin is recommended for added protection.

If the status of the source patient is unknown, their blood should be tested for HIV as soon as possible following exposure. The injured person can start antiretroviral drugs for PEP as soon as possible, preferably within three days of exposure. There is no vaccine for HIV. When the source of blood is known to be HIV positive, a 3-drug regimen is recommended by the CDC; those exposed to blood with a low viral load or otherwise low risk can use a 2-drug protocol. The antivirals are taken for 4 weeks and can include nucleoside reverse transcriptase inhibitors (NRTIs), nucleotide reverse transcriptase inhibitors (NtRTIs), Non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), or fusion inhibitors. All of these drugs can have severe side effects. PEP may be discontinued if the source of blood tests HIV-negative. Follow-up of all exposed individuals includes counseling and HIV testing for at least six months after exposure. Such tests are done at baseline, 6 weeks, 12 weeks, and 6 months and longer in specific circumstances, such as co-infection with HCV.

For idiopathic toe walking in young children, doctors may prefer to watch and wait: the child may "outgrow" the condition. If there is a reduction in the child's range of motion, there are several options.

- Wearing a brace or splint either during the day, night or both which limits the ability of the child to walk on their toes and stretches the Achilles tendon. One type of brace used is an AFO (ankle-foot orthosis).

- Serial casting where the foot is cast with the tendon stretched, and the cast is changed weekly with progressive stretching. However, these casts may not be changed weekly and instead every 2-3 weeks.

- Botox therapy is used to paralyze the calf muscles to reduce the opposition of the muscles to stretching the Achilles tendon, usually together with serial casting or splinting.

- If conservative measures fail to correct the toe walking after about 12–24 months, surgical lengthening of the tendon is an option. The surgery is typically done under full anesthesia but if there are no issues, the child is released the same day. After the surgery, a below-the-knee walking cast is worn for six weeks and then an AFO is worn to protect the tendon for several months.

For toe walking which results from more serious neuro-muscular conditions, additional specialists may need to be consulted.

Not much research has been done on the epidemiology of congenital trigger thumbs. There are a few reports on the incidence in their respective studies. The most recent data comes from a Japanese study by Kukichi and Ogino where they found an incidence 3.3 trigger thumbs per 1,000 live births in 1 year old children.

Treatment of AIT involves antibiotic treatment. Based on the offending organism found on microscopic examination of the stained fine needle aspirate, the appropriate antibiotic treatment is determined. In the case of a severe infection, systemic antibiotics are necessary. Empirical broad spectrum antimicrobial treatment provides preliminary coverage for a variety of bacteria, including "S. aureus" and "S. pyogenes." Antimicrobial options include penicillinase-resistant penicillins (ex: cloxacillin, dicloxacillin) or a combination of a penicillin and a beta-lactamase inhibitor. However, in patients with a penicillin allergy, clindamycin or a macrolide can be prescribed. The majority of anaerobic organisms involved with AIT are susceptible to penicillin. Certain Gram-negative bacilli (ex: "Prevotella", "Fusobacteria", and "Porphyromonas") are exhibiting an increased resistance based on the production of beta-lactamase. Patients who have undergone recent penicillin therapy have demonstrated an increase in beta-lactamase-producing (anaerobic and aerobic) bacteria. Clindamycin, or a combination of metronidazole and a macrolide, or a penicillin combined with a beta-lactamase inhibitor is recommended in these cases. Fungal thyroiditis can be treated with amphotericin B and fluconazole. Early treatment of AIT prevents further complications. However, if antibiotic treatment does not manage the infection, surgical drainage is required. Symptoms or indications requiring drainage include continued fever, high white blood cell count, and continuing signs of localized inflammation. The draining procedure is also based on clinical examination or ultrasound/CT scan results that indicate an abscess or gas formation. Another treatment of AIT involves surgically removing the fistula. This treatment is often the option recommended for children. However, in cases of an antibiotic resistant infection or necrotic tissue, a lobectomy is recommended. If diagnosis and/or treatment is delayed, the disease could prove fatal.

Treatment of clubfoot is evident as early as Egyptian paintings. In early days, the foot was manipulated with a Thomas wrench and casting which caused fracture of several bones in the foot. Hippocrates around 400 B.C. was the first to offer a medical explanation.

If non-operative treatments are unsuccessful or achieve incomplete correction of the deformity, surgery is sometimes needed. Surgery was more common prior to the widespread acceptance of the Ponseti Method. The extent of surgery depends on the severity of the deformity. Usually, surgery is done at 9 to 12 months of age and the goal is to correct all the components of the clubfoot deformity at the time of surgery.

For feet with the typical components of deformity (cavus, forefoot adductus, hindfoot varus, and ankle equinus), the typical procedure is a Posteromedial Release (PMR) surgery. This is done through an incision across the medial side of the foot and ankle, that extends posteriorly, and sometimes around to the lateral side of the foot. In this procedure, it is typically necessary to release (cut) or lengthen the plantar fascia, several tendons, and joint capsules/ligaments. Typically, the important structures are exposed and then sequentially released until the foot can be brought to an appropriate plantigrade position. Specifically, it is important to bring the ankle to neutral, the heel into neutral, the midfoot aligned with the hindfoot (navicula aligned with the talus, and the cuboid aligned with the calcaneus). Once these joints can be aligned, thin wires are usually placed across these joints to hold them in the corrected position. These wires are temporary and left out through the skin for removal after 3–4 weeks. Once the joints are aligned, tendons (typically the Achilles, posterior tibialis, and flexor halluces longus) are repaired at an appropriate length. The incision (or incisions) are closed with dissolvable sutures. The foot is then casted in the corrected position for 6–8 weeks. It is common to do a cast change with anesthesia after 3–4 weeks, so that pins can be removed and a mold can be made to fabricate a custom AFO brace. The new cast is left in place until the AFO is available. When the cast is removed, the AFO is worn to prevent the foot from returning to the old position.

For feet with partial correction of deformity with non-operative treatment, surgery may be less extensive and may involve only the posterior part of the foot and ankle. This might be called a posterior release. This is done through a smaller incision and may involve releasing only the posterior capsule of the ankle and subtalar joints, along with lengthening the Achilles tendon.

Surgery leaves residual scar tissue and typically there is more stiffness and weakness than with nonsurgical treatment. As the foot grows, there is potential for asymmetric growth that can result in recurrence of foot deformity that can affect the forefoot, midfoot, or hindfoot. Many patients do fine, but some require orthotics or additional surgeries. Long-term studies of adults with post-surgical clubfeet, especially those needing multiple surgeries, show that they may not fare as well in the long term, according to Dobbs, et al. Some patients may require additional surgeries as they age, though there is some dispute as to the effectiveness of such surgeries, in light of the prevalence of scar tissue present from earlier surgeries.

The natural history of disease for trigger finger remains uncertain.

There is some evidence that idiopathic trigger finger behaves differently in people with diabetes.

Recurrent triggering is unusual after successful injection and rare after successful surgery.

While difficulty extending the proximal interphalangeal joint may persist for months, it benefits from exercises to stretch the finger straighter.

The medical literature suggests a number of treatments that have been proven effective for specific cases of needle phobia, but provides very little guidance to predict which treatment may be effective for any specific case. The following are some of the treatments that have been shown to be effective in some specific cases.

- Ethyl Chloride Spray (and other freezing agents). Easily administered, but provides only superficial pain control.

- Jet Injectors. Jet Injectors work by introducing substances into the body through a jet of high pressure gas as opposed to by a needle. Though these eliminate the needle, some people report that they cause more pain. Also, they are only helpful in a very limited number of situations involving needles i.e. insulin and some inoculations.

- Iontophoresis. Iontophoresis drives anesthetic through the skin by using an electric current. It provides effective anesthesia, but is generally unavailable to consumers on the commercial market and some regard it as inconvenient to use.

- EMLA. EMLA is a topical anesthetic cream that is a eutectic mixture of lidocaine and prilocaine. It is a prescription cream in the United States, and is available without prescription in some other countries. Although not as effective as iontophoresis, since EMLA does not penetrate as deeply as iontophoresis-driven anesthetics, EMLA provides a simpler application than iontophoresis. EMLA penetrates much more deeply than ordinary topical anesthetics, and it works adequately for many individuals.

- Ametop. Ametop gel appears to be more effective than EMLA for eliminating pain during venepuncture.

- Lidocaine/tetracaine patch. A self-heating patch containing a eutectic mixture of lidocaine and tetracaine is available in several countries, and has been specifically approved by government agencies for use in needle procedures. The patch is sold under the trade name "Synera" in the United States and "Rapydan" in European Union. Each patch is packaged in an air-tight pouch. It begins to heat up slightly when the patch is removed from the packaging and exposed to the air. The patch requires 20 to 30 minutes to achieve full anesthetic effect. The Synera patch was approved by the United States Food and Drug Administration on 23 June 2005.

- Behavioral therapy. Effectiveness of this varies greatly depending on the person and the severity of the condition. There is some debate as to the effectiveness of behavioral treatments for specific phobias (like blood, injection, injury type phobias), though some data are available to support the efficacy of approaches like exposure therapy. Any therapy that endorses relaxation methods may be contraindicated for the treatment of fear of needles as this approach encourages a drop in blood pressure that only enhances the vasovagal reflex. In response to this, graded exposure approaches can include a coping component relying on applied tension as a way to prevent complications associated with the vasovagal response to specific blood, injury, injection type stimulus.

- Nitrous Oxide (Laughing Gas). This will provide sedation and reduce anxiety for the patient, along with some mild analgesic effects.

- Inhalation General Anesthesia. This will eliminate all pain and also all memory of any needle procedure. On the other hand, it is often regarded as a very extreme solution. It is not covered by insurance in most cases, and most physicians will not order it. It can be risky and expensive and may require a hospital stay.

- Benzodiazepines, such as diazepam (Valium) or lorazepam, may help alleviate the anxiety of needle phobics, according to Dr. James Hamilton. These medications have an onset of action within 5 to 15 minutes from ingestion. A relatively large oral dose may be necessary.

Since the 1980s mastitis has often been divided into non-infectious and infectious sub-groups. However, recent research suggests that it may not be feasible to make divisions in this way. It has been shown that types and amounts of potentially pathogenic bacteria in breast milk are not correlated to the severity of symptoms. Moreover, although only 15% of women with mastitis in Kvist et al.'s study were given antibiotics, all recovered and few had recurring symptoms. Many healthy breastfeeding women wishing to donate breast milk have potentially pathogenic bacteria in their milk but have no symptoms of mastitis.

A doctor will typically evaluate whether there is bilateral (both legs) toe walking, what the child's range of motion is (how far they can flex their feet) and perform a basic neurological exam. Treatment will depend on the cause of the condition.

Depending on the pet's unique condition, there are several treatment options, including surgery, chemotherapy and radiation therapy. Treating the pain adequately is also of crucial importance to improve the pet's quality of life, especially if amputation is not performed.
