The primary method for controlling the incidence of gaffkaemia is improved hygiene. Other measures include limiting damage to the exoskeleton (preventing the bacterium's entry), reducing the water temperature, and reducing the stocking density. Antibiotics may be effective against the bacterium, but only tetracycline is currently approved by the U.S Food and Drug Administration for use in American lobsters.

Antibiotics, in non-resistant strains of the pathogen, can prevent the vegetative state of the bacterium forming. Drug treatment to prevent the American foulbrood spores from successfully germinating and proliferating is possible using oxytetracycline hydrochloride (Terramycin).

Another drug treatment, tylosin tartrate, was approved by the US Food and Drug Administration (FDA) in 2005.

Chemical treatment is sometimes used prophylactically, but this is a source of considerable controversy because certain strains of the bacterium seem to be rapidly developing resistance. In addition, hives that are contaminated with millions of American foulbrood spores have to be prophylactically treated indefinitely. Once the treatment is suspended the American foulbrood spores germinate successfully again leading to a disease outbreak.

Because of the persistence of the spores (which can survive up to 40 years), many State Apiary Inspectors require an AFB diseased hive to be burned completely. A less radical method of containing the spread of disease is burning the frames and comb and thoroughly flame scorching the interior of the hive body, bottom board and covers. Dipping the hive parts in hot paraffin wax or a 3% sodium hypochlorite solution (bleach) also renders the AFB spores innocuous. It is also possible to sterilize an infected hive without damaging either the structure of the hive or the stores of honey and pollen it contains by sufficiently lengthy exposure to an atmosphere of ethylene oxide gas, as in a closed chamber, as hospitals do to sterilize equipment that cannot withstand steam sterilization.

Brigham Young University is currently studying the use of phage therapy to treat American foulbrood.

People who have been bitten by a black widow spider are recommended to seek professional medical assistance for symptoms. Symptoms self-resolve in hours to days in a majority of bites without medical intervention.

Medical treatments have varied over the years. Some treatments (e.g. calcium gluconate) have been discovered to be useless. Currently, treatment usually involves symptomatic therapy with pain medication, muscle relaxants, and antivenom. When the pain becomes unbearable, antivenom is administered. Antivenom historically completely resolves pain in a short time. Antivenom is made by injecting horses with latrodectus venom over a period of time. The horse develops antibodies against the venom. The horse is bled and the antibodies purified for later use. Doctors recommend the use of anti-inflammatory medications before antivenom administration, because antivenom can induce allergic reactions to the horse proteins. The efficacy of antivenom has come under scrutiny as patients receiving placebo have also recovered quickly.

Antivenom is used widely in Australia for redback bites; however, in the United States it is less commonly used. Antivenom made from prior spider bite victims has been used since the 1920s. Opiates such as morphine relieve pain and benzodiazepines ease muscle spasm in most patients.

There is no resistance to Citrus Black Spot and once a tree has been infected there is no known cure causing tree removal to be the best option. Both Federal and State governments have recommended the following preventative measures.

To control "Guignardia citriparpa" fungicides like copper and/or strobilurins should be applied monthly from early May to the middle of September (in the northern hemisphere). Applications of the fungicides are recommended in early April (northern hemisphere) if that month has experienced more rainfall than usual resulting in the ideal conditions for citrus black spot to form.

Table 1. Recommended Chemical Controls for Citrus Black Spot

1)Lower rates can be used on smaller trees. Do not use less than minimum label rate.

2)Mode of action class for citrus pesticides from the Fungicide Resistance Action Committee (FRAC) 20111. Refer to ENY-624, "Pesticide Resistance and Resistance Management," in the 2012 Florida Citrus Pest Management Guide for more details.

3)Do not use more than 4 applications of strobilurin fungicides/season. Do not make more than 2 sequential applications of strobilurin fungicides.

Another method of control is to accelerate the leaf litter decomposition under the trees in citrus groves. Accelerating this decomposition reduces the chance for ascospore inoculation which generally takes place in the middle of March. There are three possible methods to hasten this decomposition. One method is the increase the mircrosprinkler irrigation in the grove to half an hour for at least five days of the week. This form of control should continue for about a month and a half. The second method is to apply urea or ammonium to the leaf litter. The last and final method to accelerate leaf decomposition is to apply lime or calcium carbonate to the litter. Urea, lime, and calcium carbonate reduce the number of fungal structures and spore production. Since the fungus requires wet conditions to thrive, air flow in the citrus grove should be maximized to reduce leaf wetness.

Along with these methods it is also important to get rid of debris such as fallen fruit or twigs in a manner that reduces the chances of infecting other plants. Citrus Black Spot can colonize and reproduce on dead twigs. To dispose of citrus debris it should either be heated to a minimum of 180℉ for two hours, incinerated, buried in a landfill, or fed to livestock. Plant trash should be moved with caution if at all to avoid spreading the infectious ascospores. Any trees that are infected with citrus black spot should be removed from the grove and disposed of. These trees must be removed because those that are declining and stressed will often have off season bloom. If there is more than one age of fruit present on the tree, it is possible for the asexual spores on the fruit to be transferred to new fruit, intensifying the disease. This off season blooming is often more problematic with Valencia oranges when old and new crops overlap.

When cleaning infected cells, bees distribute spores throughout the entire colony. Disease spreads rapidly throughout the hive as the bees, attempting to remove the spore-laden dead larvae, contaminate brood food. Nectar stored in contaminated cells will contain spores and soon the brood chamber becomes filled with contaminated honey. As this honey is moved up into the supers, the entire hive becomes contaminated with spores. When the colony becomes weak from AFB infection, robber bees may enter and take contaminated honey back to their hives thereby spreading the disease to other colonies and apiaries. Beekeepers also may spread disease by moving equipment (frames or supers) from contaminated hives to healthy ones.

American foulbrood spores are extremely resistant to desiccation and can remain viable for more than 40 years in honey and beekeeping equipment. Therefore, honey from an unknown source should never be used as bee feed, and used beekeeping equipment should be assumed contaminated unless known to be otherwise.

Gaffkaemia was first discovered in 1947 in American lobsters ("Homarus americanus") in a holding tank in Maine. It was originally described as ""Gaffkya homari"" by Hitcher and Snieszko, but the genus name "Gaffkya" was rejected in 1971, and the gaffkaemia bacterium was recognised as a subspecies or variety of "Aerococcus viridans" by Kelly and Evans in 1974.

Treatment for gastroenteritis due to "Y. enterocolitica" is not needed in the majority of cases. Severe infections with systemic involvement (sepsis or bacteremia) often requires aggressive antibiotic therapy; the drugs of choice are doxycycline and an aminoglycoside. Alternatives include cefotaxime, fluoroquinolones, and co-trimoxazole.

In the US, neuroborreliosis is typically treated with intravenous antibiotics which cross the blood–brain barrier, such as penicillins, ceftriaxone, or cefotaxime. One relatively small randomized controlled trial suggested ceftriaxone was more effective than penicillin in the treatment of neuroborreliosis. Small observational studies suggest ceftriaxone is also effective in children. The recommended duration of treatment is 14 to 28 days.

Several studies from Europe have suggested oral doxycycline is equally as effective as intravenous ceftriaxone in treating neuroborreliosis. Doxycycline has not been widely studied as a treatment in the US, but antibiotic sensitivities of prevailing European and US isolates of "Borrelia burgdorferi" tend to be identical. However, doxycycline is generally not prescribed to children due to the risk of bone and tooth damage.

Discreditied or doubtful treatments for neuroborreliosis include:

- Malariotherapy

- Hyperbaric oxygen therapy

- Colloidal silver

- Injections of hydrogen peroxide and bismacine

Several health authorities have issued related guidance documents, which need to be considered for drug development:

- ICH (International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use)

- M3(R2) "Guidance on Nonclinical Safety Studies for the Conduct of Human Clinical Trials and Marketing Authorization for Pharmaceuticals"

- S9 "Nonclinical Evaluation for Anticancer Pharmaceuticals"

- S10 "Photosafety Evaluation"

- EMA (European Medicines Agency)

- "Note for Guidance on Photosafety Testing" (revision on-hold)

- "Question & Answers on the Note for Guidance on Photosafety Testing"

- FDA (U.S. Food and Drug Administration)

- MHLW/PMDA (Japanese Ministry of Health, Labour and Welfare / Pharmaceuticals and Medical Devices Agency)

The drug tafamidis has completed a phase II/III 18-month-long placebo controlled clinical trial

and these results in combination with an 18-month follow-on study demonstrated that Tafamidis or Vyndaqel slowed progression of FAP, particularly when administered to patients early in the course of FAP. This drug is now approved by the European Medicines Agency.

The US Food and Drug Administration's Peripheral and Central Nervous System Drugs Advisory Committee rejected the drug in June 2012, in a 13-4 vote. The committee stated that there was not enough evidence supporting efficacy of the drug, and requested additional clinical trials.

In the absence of a liver transplant, FAP is invariably fatal, usually within a decade. The disadvantage of liver transplantation is that approximately 10% of the subjects die from the procedure or complications resulting from the procedure, which is a form of gene therapy wherein the liver expressing wild type and mutant TTR is replaced by a liver only expressing wild type TTR. Moreover, transplanted patients must take immune suppressants (drugs) for the remainder of their life, which can lead to additional complications. In late 2011, the European Medicines Agency approved the transthyretin kinetic stabilizer Tafamidis or Vyndaqel discovered by Jeffery W. Kelly and developed by FoldRx pharmaceuticals (acquired by Pfizer in 2010) for the treatment of FAP based on clinical trial data. Tafamidis (20 mg once daily) slowed the progression of FAP over a 36-month period and importantly reversed the weight loss and muscle wasting associated with disease progression.

Infection with "Aphanomyces astaci" is accompanied by few signs in its early stages, and the first indication of infection may be mortality. In the later stages, the muscles of the tail may appear whitened, or brownish-red where blood cells have encapsulated the hyphae. The effects of the neurotoxins in the oomycete can include appearing in daytime (crayfish are typically nocturnal) and a lack of coordination.

Treatment consists of immunoglobulin replacement therapy, which replenishes Ig subtypes that the person lack. This treatment is given at frequent intervals for life, and is thought to help reduce bacterial infections and boost immune function. Before therapy begins, plasma donations are tested for known blood-borne pathogens, then pooled and processed to obtain concentrated IgG samples. Infusions can be administered in three different forms: intravenously (IVIg):, subcutaneously (SCIg), and intramuscularly (IMIg).

The administration of intravenous immunoglobulins requires the insertion of a cannula or needle in a vein, usually in the arms or hands. Because highly concentrated product is used, IVIg infusions take place every 3 to 4 weeks. Subcutaneous infusions slowly release the Ig serum underneath the skin, again through a needle, and takes place every week. Intramuscular infusions are no longer widely used, as they can be painful and are more likely to cause reactions.

People often experience adverse side effects to immunoglobulin infusions, including:

- swelling at the insertion site (common in SCIG)

- chills

- headache

- nausea (common in IVIG)

- fatigue (common in IVIG)

- muscle aches and pain, or joint pain

- fever (common in IVIG and rare in SCIG)

- hives (rare)

- thrombotic events (rare)

- aseptic meningitis (rare, more common in people with SLE)

- anaphylactic shock (very rare)

In addition to Ig replacement therapy, treatment may also involve immune suppressants, to control autoimmune symptoms of the disease, and high dose steroids like corticosteroids. In some cases, antibiotics are used to fight chronic lung disease resulting from CVID. The outlook for people varies greatly depending on their level of lung and other organ damage prior to diagnosis and treatment.

Although no specific treatment for acute infection with SuHV1 is available, vaccination can alleviate clinical signs in pigs of certain ages. Typically, mass vaccination of all pigs on the farm with a modified live virus vaccine is recommended. Intranasal vaccination of sows and neonatal piglets one to seven days old, followed by intramuscular (IM) vaccination of all other swine on the premises, helps reduce viral shedding and improve survival. The modified live virus replicates at the site of injection and in regional lymph nodes. Vaccine virus is shed in such low levels, mucous transmission to other animals is minimal. In gene-deleted vaccines, the thymidine kinase gene has also been deleted; thus, the virus cannot infect and replicate in neurons. Breeding herds are recommended to be vaccinated quarterly, and finisher pigs should be vaccinated after levels of maternal antibody decrease. Regular vaccination results in excellent control of the disease. Concurrent antibiotic therapy via feed and IM injection is recommended for controlling secondary bacterial pathogens.

Hydroquinone solution was often mixed in an oil-free moisturizer that acted like a skin bleach. However the use of hydroquinone for skin whitening has been banned in European countries due to health concerns. In 2006, the United States Food and Drug Administration revoked its approval of hydroquinone for over the counter preparations warning that it may cause cancer or have many other detrimental effects.

The use of hydroquinone skin-whitening products can be toxic, harmful or lethal for humans.

Modern treatments include topical creams that are marketed for the condition (e.g. L'Oreal, Olay, Skin Doctors etc.). Various ingredients have been researched, developed and included in these creams. For example, recently, chemical compounds called alpha hydroxy acids (AHAs) have been added as a beneficial ingredient to creams for dark circles. Specialist treatments including laser and intense pulsed light skin surgery can also be used.

Within all classes of medicinal drugs that possibly can lead to pulmonary toxicity as a side effect, most pulmonary toxicity is due to chemotherapy for cancer.

Many medicinal drugs can lead to pulmonary toxicity. A few medicinal drugs can lead to pulmonary toxicity frequently (in medicine defined by international regulatory authorities such as the U.S. Food and Drug Administration and the EMEA [European Union] as > 1% and 10%). These medicinal drugs can include gold and nitrofurantoin, as well as the following drugs used in chemotherapy for cancer: Methotrexate, the taxanes (paclitaxel and docetaxel), gemcitabine, bleomycin, mitomycin C, busulfan, cyclophosphamide, chlorambucil, and nitrosourea (e.g., carmustine).

Also, some medicinal drugs used in cardiovascular medicine can lead to pulmonary toxicity frequently or very frequently. These include above all amiodarone, as well as beta blockers, ACE inhibitors (however, pulmonary toxicity of ACE inhibitors usually lasts only 3–4 months and then usually disappears by itself), procainamide, quinidine, tocainide, and minoxidil.

Both oncologists and cardiologists are well aware of possible pulmonary toxicity.

Far East scarlet-like fever or scarlatinoid fever is an infectious disease caused by the gram negative bacillus "Yersinia pseudotuberculosis". In Japan it is called Izumi fever.

Crayfish plague, "Aphanomyces astaci", is a water mold that infects crayfish, most notably the European "Astacus" which dies within a few weeks of being infected. When experimentally tested, species from Australia, New Guinea and Japan were also found to be susceptible to the infection.

Prednisone is the drug of choice for PMR, and treatment duration is frequently greater than one year. If the patient does not experience dramatic improvement after three days of 10–20 mg oral prednisone per day, the diagnosis should be reconsidered. Sometimes relief of symptoms occurs in only several hours.

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are ineffective in the initial treatment of PMR, but they may be used in conjunction with the maintenance dose of corticosteroid.

Along with medical treatment, patients are encouraged to exercise and eat healthily--helping to maintain a strong immune system and build strong muscles and bones. A diet of fruits, vegetables, whole grains, and low-fat meat and dairy products, avoiding foods with high levels of refined sugars and salt is recommended.

The European Food Safety Authority concluded that chromium is not an essential nutrient, making this the only mineral for which the United States and the European Union disagree. The proposed mechanism for cellular uptake of Cr via transferrin has been called into question. There is no proof that chromium supplementation has physiological effects on body mass or composition, and its use as a supplement may be unsafe. A 2014 systematic review concluded that chromium supplementation had no effect on glycemic control, fasting plasma glucose levels, or body weight in people with or without diabetes.

Chromium may be needed as an ingredient in total parenteral nutrition (TPN), since deficiency may occur after months of intravenous feeding with chromium-free TPN. For this reason, chromium is added to normal TPN solutions for people with diabetes, and in nutritional products for preterm infants.

Genetic mutations of most forms of dwarfism caused by bone dysplasia cannot be altered yet, so therapeutic interventions are typically aimed at preventing or reducing pain or physical disability, increasing adult height, or mitigating psychosocial stresses and enhancing social adaptation.

Forms of dwarfism associated with the endocrine system may be treated using hormonal therapy. If the cause is prepubescent hyposecretion of growth hormone, supplemental growth hormone may correct the abnormality. If the receptor for growth hormone is itself affected, the condition may prove harder to treat. Hypothyroidism is another possible cause of dwarfism that can be treated through hormonal therapy. Injections of thyroid hormone can mitigate the effects of the condition, but lack of proportion may be permanent.

Pain and disability may be ameliorated by physical therapy, braces or other orthotic devices, or by surgical procedures. The only simple interventions that increase perceived adult height are dress enhancements, such as shoe lifts or hairstyle. Growth hormone is rarely used for shortness caused by bone dysplasias, since the height benefit is typically small (less than ) and the cost high. The most effective means of increasing adult height by several inches is distraction osteogenesis, though availability is limited and the cost is high in terms of money, discomfort, and disruption of life. Most people with dwarfism do not choose this option, and it remains controversial. For other types of dwarfism, surgical treatment is not possible.

Radiation (radiotherapy) is frequently used for the treatment of many cancer types, and can be highly effective. Unfortunately, it also can lead to pulmonary toxicity as a side effect.

Radiotherapists are well aware of possible pulmonary toxicity, and take a number of precautions to minimise the incidence of this side effect. There are research efforts to possibly eliminate this side effect in the future.

As with most other fatty acid oxidation disorders, individuals with MCADD need to avoid fasting for prolonged periods of time. During illnesses, they require careful management to stave off metabolic decompensation, which can result in death. Supplementation of simple carbohydrates or glucose during illness is key to prevent catabolism. The duration of fasting for individuals with MCADD varies with age, infants typically require frequent feedings or a slow release source of carbohydrates, such as uncooked cornstarch. Illnesses and other stresses can significantly reduce the fasting tolerance of affected individuals.

Individuals with MCADD should have an "emergency letter" that allows medical staff who are unfamiliar with the patient and the condition to administer correct treatment properly in the event of acute decompensation. This letter should outline the steps needed to intervene in a crisis and have contact information for specialists familiar with the individual's care.

Misdiagnosis issues

- The MCADD disorder is commonly mistaken for Reye Syndrome by pediatricians. Reye Syndrome is a severe disorder that may develop in children while they appear to be recovering from viral infections such as chicken pox or flu.

- Most cases of Reye Syndrome are associated with the use of Aspirin during these viral infections.

3T3 Neutral Red Phototoxicity Test – An in vitro toxicological assessment test used to determine the cytotoxic and photo(cyto)toxicity effect of a test article to murine fibroblasts in the presence or absence of UVA light.

"The 3T3 Neutral Red Uptake Phototoxicity Assay (3T3 NRU PT) can be utilized to identify the phototoxic effect of a test substance induced by the combination of test substance and light and is based on the comparison of the cytotoxic effect of a test substance when tested after the exposure and in the absence of exposure to a non-cytotoxic dose of UVA/vis light. Cytotoxicity is expressed as a concentration-dependent reduction of the uptake of the vital dye - Neutral Red.

Substances that are phototoxic in vivo after systemic application and distribution to the skin, as well as compounds that could act as phototoxicants after topical application to the skin can be identified by the test. The reliability and relevance of the 3T3 NRU PT have been evaluated and has been shown to be predictive when compared with acute phototoxicity effects in vivo in animals and humans."

SuHV1 can be used to analyze neural circuits in the central nervous system (CNS). For this purpose the attenuated (less virulent) Bartha SuHV1 strain is commonly used and is employed as a retrograde and anterograde transneuronal tracer. In the retrograde direction, SuHV1-Bartha is transported to a neuronal cell body via its axon, where it is replicated and dispersed throughout the cytoplasm and the dendritic tree. SuHV1-Bartha released at the synapse is able to cross the synapse to infect the axon terminals of synaptically connected neurons, thereby propagating the virus; however, the extent to which non-synaptic transneuronal transport may also occur is uncertain. Using temporal studies and/or genetically engineered strains of SuHV1-Bartha, second, third, and higher order neurons may be identified in the neural network of interest.
