Treatment of LPI consists of protein-restricted diet and supplementation with oral citrulline. Citrulline is a neutral amino acid that improves the function of the urea cycle and allows sufficient protein intake without hyperammonemia. Under proper dietary control and supplementation, the majority of the LPI patients are able to have a nearly normal life. However, severe complications including pulmonary alveolar proteinosis and renal insufficiency may develop even with proper treatment.

Fertility appears to be normal in women, but mothers with LPI have an increased risk for complications during pregnancy and delivery.

The main treatment for acral erythema is discontinuation of the offending drug, and symptomatic treatment to provide analgesia, lessen edema, and prevent superinfection. However, the treatment for the underlying cancer of the patient must not be neglected. Often, the discontinued drug can be substituted with another cancer drug or cancer treatment.

Symptomatic treatment can include wound care, elevation, and pain medication. Corticosteroids and pyridoxine have also been used to relieve symptoms. Other studies do not support the conclusion.

A number of additional remedies are listed in recent medical literature. Among them henna and 10% uridine ointment which went through clinical trial.

The cooling of hands and feet during chemotherapy may help prevent PPE (Baack and Burgdorf, 1991; Zimmerman et al., 1995). Support for this and a variety of other approaches to treat or prevent acral erythema comes from small clinical studies, although none has been proven in a randomised controlled clinical trial of sufficient size.

Two small randomized controlled trials (RCTs) and one larger RCT (86 subjects) tested glutamine in the prevention of platinum treatment-induced neuropathy and showed promise. As of September 2013 a larger, placebo-controlled trial is running.

A 2013 systematic review of the use of acetyl-L-carnitine, glutamine, vitamin E, glutathione, vitamin B6, omega-3 fatty acids, magnesium, calcium, alpha lipoic acid and n-acetyl cysteine as anti-CIPN adjuvants concluded that "currently no agent has shown solid beneficial evidence to be recommended for the treatment or prophylaxis of CIPN."

In most of the reported cases, the treatment options were very similar. Plasmapheresis alone or in combination with steroids, sometimes also with thymectomy and azathioprine, have been the most frequently used therapeutic approach in treating Morvan’s Syndrome. However, this does not always work, as failed response to steroids and to subsequently added plasmapheresis have been reported. Intravenous immunoglobulin was effective in one case.

In one case, the dramatic response to high-dose oral prednisolone together with pulse methylprednisolone with almost complete disappearance of the symptoms within a short period should induce consideration of corticosteroids.

In another case, the subject was treated with haloperidol (6 mg/day) with some improvement in the psychomotor agitation and hallucinations, but even high doses of carbamazepine given to the subject failed to improve the spontaneous muscle activity. Plasma Exchange (PE) was initiated, and after the third such session, the itching, sweating, mental disturbances, and complex nocturnal behavior improved and these symptoms completely disappeared after the sixth session, with improvement in insomnia and reduced muscle twitching. However, one month after the sixth PE session, there was a progressive worsening of insomnia and diurnal drowsiness, which promptly disappeared after another two PE sessions.

In one case there high dose steroid treatment resulted in a transient improvement, but aggressive immuno-suppressive therapy with cyclophosphamide was necessary to control the disease and result in a dramatic clinical improvement.

In another case, the subject was treated with prednisolone (1 mg/kg body weight) with carbamazepine, propanolol, and amitriptyline. After two weeks, improvement with decreased stiffness and spontaneous muscle activity and improved sleep was observed. After another 7–10 days, the abnormal sleep behavior disappeared completely.

In another case, symptomatic improvement with plasmapheresis, thymectomy, and chronic immunosuppression provide further support for an autoimmune or paraneoplastic basis.

Although thymectomy is believed to be a key element in the proposed treatment, there is a reported case of Morvan’s Syndrome presenting itself post-thymectomy.

In a study of patients receiving oxaliplatin treatment, only 4 percent of those also receiving intravenous calcium and magnesium (ca/mg) before and after each oxaliplatin dose had to discontinue treatment due to neurotoxicity, compared to 33 percent who were receiving intravenous placebo; onset of neuropathy was also significantly delayed in the ca/mg patients, and only 22 percent of the ca/mg patients had long-term CIPN of grade 2 or worse compared with 41 percent of those on placebo. Overall, trials of ca/mg infusion suggest there are no serious harmful side effects and it may be an effective preventative therapy — the number of patients so far studied is small, however, and confident conclusions cannot be drawn.

SJS constitutes a dermatological emergency. Patients with documented "Mycoplasma" infections can be treated with oral macrolide or oral doxycycline.

Initially, treatment is similar to that for patients with thermal burns, and continued care can only be supportive (e.g. intravenous fluids and nasogastric or parenteral feeding) and symptomatic (e.g., analgesic mouth rinse for mouth ulcer). Dermatologists and surgeons tend to disagree about whether the skin should be debrided.

Beyond this kind of supportive care, no treatment for SJS is accepted. Treatment with corticosteroids is controversial. Early retrospective studies suggested corticosteroids increased hospital stays and complication rates. No randomized trials of corticosteroids were conducted for SJS, and it can be managed successfully without them.

Other agents have been used, including cyclophosphamide and cyclosporin, but none has exhibited much therapeutic success. Intravenous immunoglobulin treatment has shown some promise in reducing the length of the reaction and improving symptoms. Other common supportive measures include the use of topical pain anesthetics and antiseptics, maintaining a warm environment, and intravenous analgesics.

An ophthalmologist should be consulted immediately, as SJS frequently causes the formation of scar tissue inside the eyelids, leading to corneal vascularization, impaired vision, and a host of other ocular problems. Those with chronic ocular surface disease caused by SJS may find some improvement with PROSE treatment (prosthetic replacement of the ocular surface ecosystem treatment).

Currently there is no cure for these disorders. Medical care is directed at treating systemic conditions and improving the person's quality of life. Physical therapy and daily exercise may delay joint problems and improve the ability to move.

Changes to the diet will not prevent disease progression, but limiting milk, sugar, and dairy products has helped some individuals experiencing excessive mucus.

Surgery to remove tonsils and adenoids may improve breathing among affected individuals with obstructive airway disorders and sleep apnea. Sleep studies can assess airway status and the possible need for nighttime oxygen. Some patients may require surgical insertion of an endotrachial tube to aid breathing. Surgery can also correct hernias, help drain excessive cerebrospinal fluid from the brain, and free nerves and nerve roots compressed by skeletal and other abnormalities. Corneal transplants may improve vision among patients with significant corneal clouding.

Enzyme replacement therapy (ERT) are currently in use or are being tested. Enzyme replacement therapy has proven useful in reducing non-neurological symptoms and pain. Currently BioMarin Pharmaceutical produces enzyme replacement therapies for MPS type I and VI. Aldurazyme is an enzymatic replacement therapy for alpha-L-iduronidase produced by BioMarin for use in Type I MPS. In July 2006, the United States Food and Drug Administration approved a synthetic version of I2S produced by Shire Pharmaceuticals Group, called Elaprase, as a treatment for MPS type II (Hunter syndrome).

Bone marrow transplantation (BMT) and umbilical cord blood transplantation (UCBT) have had limited success in treating the mucopolysaccharidoses. Abnormal physical characteristics, except for those affecting the skeleton and eyes, may be improved, but neurologic outcomes have varied. BMT and UCBT are high-risk procedures and are usually performed only after family members receive extensive evaluation and counseling.

Currently there is no cure for PWS. Treatment differs from person to person and depends on the extent and severity of the blood vessels malformations and the degree of correction possible. The treatments can only control for the symptoms and often involve a multidisciplinary care as mentioned in diagnosis. AVMs and AVFs are treated with surgery or with embolization. If there are differences in the legs because of overgrowth in the affected limb, then the patient is referred to an orthopedist. If legs are affected to a minimal degree, then the patient may find heel inserts to be useful as they adjust for the different lengths in the legs and can walk normally.The port-wine stains may be treated by dermatologists. Supportive care is necessary and may include compression garments. These garments are tight-fitting clothing on the affected limb and helps with reducing pain and swelling. This can also help with protecting the limb from bumps and scrapes that cause bleeding. Also again based on the symptoms, the doctors may recommend antibiotics or pain medications.

Surgical care might also be an option for PWS patients. Surgeons may perform debulking procedure in which abnormal and overgrown tissues are removed. If PWS is affecting a foot or leg, the limbs can become quite large. And orthopedic surgeon can operate on the limb to reshape the limb. If the growth of the limb is more than one inch a procedure called epiphysiodesis may be performed. This procedure interrupts the growth of the leg and stops the leg from growing too big.

Other treatment options include: embolization and laser therapy. Embolization includes a substance injected by an interventional radiologists that can help in the elimination of the abnormal connections between the arteries and veins. According to Parkes Weber syndrome—Diagnostic and management paradigms: A systematic review, published in July 2017, reported that embolization alone or in combination with surgical removal of arteriovenous malformations leads to significant clinical improvement. Laser therapy can also help lighten capillary malformations and can speed up the healing process of the bleeding lesions.

Also other specialists are needed for dealing with the progression of the disease such as: physical therapists, occupational therapists and counselors. Physical therapists can help ease the pain and increase the range of movements of the arm or leg that is overgrown. Occupational therapists could help with the development of motor skills impeded by physical problems. The classic port-wine stains may make the patient feel uncomfortable and counselors can help with the psychological and social issues.

PWS is a progressive condition and advances with age. It is dependent on: the extent of the disease and overgrowth, condition of the patient’s heart, if the blood vessels are responsive to treatment, overall health of the patient, tolerance of medications and treatments. Based on these factors the prognosis is fair to good. The deformity and overgrowth tend to progress with time until epiphyseal closure. A lot of medical attention is needed to correct the blood vessels.

Lysinuric protein intolerance (LPI), also called hyperdibasic aminoaciduria type 2,cationic aminoaciduria or familial protein intolerance, is an autosomal recessive metabolic disorder affecting amino acid transport.

About 140 patients have been reported, almost half of them of Finnish origin. Individuals from Japan, Italy, Morocco and North Africa have also been reported.

Immunosuppressive therapies, encompassing corticosteroids, azathioprine, methotrexate and more recently, rituximab, are the mainstay of therapy. Other treatments include PE, IVIG, and thymectomy. Patients reportedly exhibited a heterogenous response to immunomodulation.

Antiepileptics can be used for symptomatic relief of peripheral nerve hyperexcitability. Indeed, some patients have exhibited a spontaneous remission of symptoms.

Emergency treatment of cocaine-associated hyperthermia consists of administering a benzodiazepine sedation agent, such as diazepam (Valium) or lorazepam (Ativan) to enhance muscle relaxation and decrease sympathetic outflow from the central nervous system. Physical cooling is best accomplished with tepid water misting and cooling with a fan (convection and evaporation), which can be carried out easily in the field or hospital. There is no specific pharmacological antidote for cocaine overdose. The chest pain, high blood pressure, and increased heart rate caused by cocaine may be also treated with a benzodiazepine. Multiple and escalating dose of benzodiazepines may be necessary to achieve effect, which increases risk of over-sedation and respiratory depression. A comprehensive systematic review of all pharmacological treatments of cocaine cardiovascular toxicity revealed benzodiazepines may not always reliably lower heart rate and blood pressure.

Nitric-oxide mediated vasodilators, such as nitroglycerin and nitroprusside, are effective at lowering blood pressure and reversing coronary arterial vasoconstriction, but not heart rate. Nitroglycerin is useful for cocaine-induced chest pain, but the possibility of reflex tachycardia must be considered. Alpha-blockers such as phentolamine have been recommended and may be used to treat cocaine-induced hypertension and coronary arterial vasoconstriction, but these agents do not reduce heart rate. Furthermore, phentolamine is rarely used, not readily available in many emergency departments, and many present-day clinicians are unfamiliar with its use and titratability. Calcium channel blockers may also be used to treat hypertension and coronary arterial vasoconstriction, but fail to lower tachycardia based on all cocaine-related studies. Non-dihydropyridine calcium channels blockers such as diltiazem and verapamil are preferable, as dihydropyridine agents such as nifedipine have much higher risk of reflex tachycardia.

Agitated patients are best treated with benzodiazepines, but antipsychotics such as haloperidol and olanzapine may also be useful. The alpha-2 agonist dexmedetomidine may also be useful for treatment of agitation, but effects on heart rate and blood pressure are variable based on several studies and case reports. Lidocaine and intravenous lipid emulsion have been successfully used for serious ventricular tachyarrhythmias in several case reports.

The use of beta-blockers for cocaine cardiovascular toxicity has been subject to a relative contraindication by many clinicians for several years despite extremely limited evidence. The phenomenon of “unopposed alpha-stimulation,” in which blood pressure increases or coronary artery vasoconstriction worsens after blockade of beta-2 vasodilation in cocaine-abusing patients, is controversial. This rarely-encountered and unpredictable adverse effect has resulted in some clinicians advocating for an absolute contraindication of the use of all beta-blockers, including specific, non-specific, and mixed. Many clinicians have disregarded this dogma and administer beta-blockers for cocaine-related chest pain and acute coronary syndrome, especially when there is demand ischemia from uncontrolled tachycardia. Of the 1,744 total patients identified in the aforementioned systematic review, only 7 adverse events were from putative cases of “unopposed alpha-stimulation” due to propranolol (n=3), esmolol (n=3), and metoprolol (n=1). Some detractors of beta-blockers for cocaine-induced chest pain have cited minimal acute mortality and the short half-life of the drug, making it unnecessary to aggressively treat any associated tachycardia and hypertension. However, the long-term effect of cocaine use and development of heart failure, with early mortality, high morbidity, and tremendous demand on hospital utilization should be taken under consideration.

The mixed beta/alpha blocker labetalol has been shown to be safe and effective for treating concomitant cocaine-induced hypertension and tachycardia, without any “unopposed alpha-stimulation” adverse events recorded. The use of labetalol is approved by a recent AHA/ACC guideline for cocaine and methamphetamine patients with unstable angina/non-STEMI.

On June 30, 2009, an FDA advisory panel recommended that Vicodin and another painkiller, Percocet, be removed from the market because they have allegedly caused over 400 deaths a year. The problem is with paracetamol (acetaminophen/Tylenol for example ) overdose and liver damage. These two drugs, in combination with other drugs like Nyquil and Theraflu, can cause death by multiple drug intake and/or drug overdose. Another solution would be to not include paracetamol with Vicodin or Percocet.

SJS (with less than 10% of body surface area involved) has a mortality rate of around 5%. The mortality for toxic epidermal necrolysis (TEN) is 30–40%. The risk for death can be estimated using the SCORTEN scale, which takes a number of prognostic indicators into account. It is helpful to calculate a SCORTEN within the first 3 days of hospitalization. Other outcomes include organ damage/failure, cornea scratching, and blindness.. Restrictive lung disease may develop in patients with SJS and TEN after initial acute pulmonary involvement. Patients with SJS or TEN caused by a drug have a better prognosis the earlier the causative drug is withdrawn.

Specific pretreatments, drugs to prevent chemically induced lung injuries due to respiratory airway toxins, are not available. Analgesic medications, oxygen, humidification, and ventilator support currently constitute standard therapy. In fact, mechanical ventilation remains the therapeutic mainstay for acute inhalation injury. The cornerstone of treatment is to keep the PaO2 > 60 mmHg (8.0 kPa), without causing injury to the lungs with excessive O2 or volutrauma. Pressure control ventilation is more versatile than volume control, although breaths should be volume limited, to prevent stretch injury to the alveoli. Positive end-expiratory pressure (PEEP) is used in mechanically ventilated patients with ARDS to improve oxygenation. Hemorrhaging, signifying substantial damage to the lining of the airways and lungs, can occur with exposure to highly corrosive chemicals and may require additional medical interventions. Corticosteroids are sometimes administered, and bronchodilators to treat bronchospasms. Drugs that reduce the inflammatory response, promote healing of tissues, and prevent the onset of pulmonary edema or secondary inflammation may be used following severe injury to prevent chronic scarring and airway narrowing.

Although current treatments can be administered in a controlled hospital setting, many hospitals are ill-suited for a situation involving mass casualties among civilians. Inexpensive positive-pressure devices that can be used easily in a mass casualty situation, and drugs to prevent inflammation and pulmonary edema are needed. Several drugs that have been approved by the FDA for other indications hold promise for treating chemically induced pulmonary edema. These include β2-agonists, dopamine, insulin, allopurinol, and non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen. Ibuprofen is particularly appealing because it has an established safety record and can be easily administered as an initial intervention. Inhaled and systemic forms of β2-agonists used in the treatment of asthma and other commonly used medications, such as insulin, dopamine, and allopurinol have also been effective in reducing pulmonary edema in animal models but require further study. A recent study documented in the "AANA Journal" discussed the use of volatile anesthetic agents, such as sevoflurane, to be used as a bronchodilator that lowered peak airway pressures and improved oxygenation. Other promising drugs in earlier stages of development act at various steps in the complex molecular pathways underlying pulmonary edema. Some of these potential drugs target the inflammatory response or the specific site(s) of injury. Others modulate the activity of ion channels that control fluid transport across lung membranes or target surfactant, a substance that lines the air sacs in the lungs and prevents them from collapsing. Mechanistic information based on toxicology, biochemistry, and physiology may be instrumental in determining new targets for therapy. Mechanistic studies may also aid in the development of new diagnostic approaches. Some chemicals generate metabolic byproducts that could be used for diagnosis, but detection of these byproducts may not be possible until many hours after initial exposure. Additional research must be directed at developing sensitive and specific tests to identify individuals quickly after they have been exposed to varying levels of chemicals toxic to the respiratory tract.

Currently there are no clinically approved agents that can reduce pulmonary and airway cell dropout and avert the transition to pulmonary and /or airway fibrosis.

In general, the simultaneous use of multiple drugs should be carefully monitored by a qualified individual such as board certified and licensed medical doctor, either an MD or DO Close association between prescribing physicians and pharmacies, along with the computerization of prescriptions and patients' medical histories, aim to avoid the occurrence of dangerous drug interactions. Lists of contraindications for a drug are usually provided with it, either in monographs, package inserts (accompanying prescribed medications), or in warning labels (for OTC drugs). CDI/MDI might also be avoided by physicians requiring their patients to return any unused prescriptions. Patients should ask their doctors and pharmacists if there are any interactions between the drugs they are taking.

A complete recovery following immunotherapy and tumor removal. Untreated cases died within few months of onset. Some patients have a poor outcome despite sustained immunosuppression, but that is often related to tumor progression or associated with the presence of Abs directed against intracellular Ags such as GAD Abs or amphyphysin Abs, which can reflect the involvement of an additional cytotoxic T-cell mechanism in the progression of the disease.

Continuous prophylactic antiepileptic drug (AED) treatment may not be needed particularly for children with only 1-2 or brief seizures. This is probably best reserved for children whose seizures are unusually frequent, prolonged, distressing, or otherwise significantly interfering with the child’s life. There is no evidence of superiority of monotherapy with any particular common AED.

Autonomic status epilepticus in the acute stage needs thorough evaluation for proper diagnosis and assessment of the neurologic/autonomic state of the child. "Rescue" benzodiazepines are commonly used to terminate it. Aggressive treatment should be avoided because of the risk of iatrogenic complications, including cardiovascular arrest. There is some concern that intravenous lorazepam and/or diazepam may precipitate cardiovascular arrest. Early parental treatment is more effective than late emergency treatment. Buccal midazolam is probably the first choice medication for out of hospital termination of autonomic status epilepticus which should be administered as soon as the child shows evidence of onset of its habitual autonomic seizures.

Parental education about Panayiotopoulos syndrome is the cornerstone of correct management. The traumatizing, sometimes long-lasting effect on parents is significant particularly because autonomic seizures may last for many hours compounded by physicians’ uncertainty regarding diagnosis, management, and prognosis.

There is no cure for Machado-Joseph Disease. However, treatments are available for some symptoms. For example, spasticity can be reduced with antispasmodic drugs, such as baclofen. The Parkinsonian symptoms can be treated with levodopa therapy. Prism glasses can reduce diplopic symptoms. Physiotherapy/Physical Therapy and/or occupational therapy can help patients by prescribing mobility aids to increase the patients' independence, providing gait training, and prescribing exercises to maintain the mobility of various joints and general health to decrease the likelihood of falls or injuries as a result of falls. Walkers and wheelchairs can greatly help the patient with everyday tasks. Some patients will experience difficulties with speech and swallowing, therefore a Speech-Language Pathologist can assist the patients to improve their communicating abilities and their issues with swallowing.

Although there are many short- term preventative methods in place to combat childhood, there are some individuals who return to their initial base weight and therefore might turn to surgical measures to achieve a more lasting effect. Bariatric surgery is an effective procedure used to restrict the patients food intake and decrease absorption of food in the stomach and intestines. Proecdures of this type are said to be able to reduce excess body weight of obese or overweight individuals by 50-75%, ultimately maintaining this weight loss for 16 years following.

There is currently no known pharmacological treatment to hereditary motor and sensory neuropathies. However, the majority of people with these diseases are able to walk and be self-sufficient. Some methods of relief for the disease include physical therapy, stretching, braces, and sometimes orthopedic surgery. Since foot disorders are common with neuropathy disorders precautions must be taken to strengthen these muscles and use preventative care and physical therapy to prevent injury and deformities.

According to NIH clinical trials.gov, research on the port-wine stain and its relation to polymorphisms of RASA1 has commenced in November 2010 and expected to end in November 2019. The purpose of the study is to assess how the port-wine stains can lead to complex syndromes such as PWS. Currently there is little knowledge about the epidemiology of the stains and how they progress with the disease. The research is ongoing and the results are yet to be published.

In an another review published in July 2017 (discussed in treatments and prognosis), Banzic et. al. discussed clinical findings that embolization works really well in patients with PWS. Also, embolization along with surgical resection that targets arteriovenous malformations reliably leads to significant clinical improvements.

Exercise is a promising mechanism of prevention and treatment for various diseases characterized by neuroinflammation. Aerobic exercise is used widely to reduce inflammation in the periphery. Exercise has been shown to decreases proliferation of microglia in the brain, decrease hippocampal expression of immune-related genes, and reduce expression of inflammatory cytokines such as TNF-α.
