Topical treatment for the skin changes of scleroderma do not alter the disease course, but may improve pain and ulceration. A range of NSAIDs (nonsteroidal anti-inflammatory drugs) can be used to ease painful symptoms, such as naproxen. There is limited benefit from steroids such as prednisone. Episodes of Raynaud's phenomenon sometimes respond to nifedipine or other calcium channel blockers; severe digital ulceration may respond to prostacyclin analogue iloprost, and the dual endothelin-receptor antagonist bosentan may be beneficial for Raynaud's phenomenon. The skin tightness may be treated systemically with methotrexate and ciclosporin. and the skin thickness treated with penicillamine.
Scleroderma renal crisis, the occurrence of acute renal failure and malignant hypertension (very high blood pressure with evidence of organ damage) in people with scleroderma, is effectively treated with drugs from the class of the ACE inhibitors. The benefit of ACE inhibitors extends even to those who have to commence dialysis to treat their kidney disease, and may give sufficient benefit to allow the discontinuation of renal replacement therapy.
No definite standard treatment have been set. This is because treatments of the disease has been poorly studied as of 2014. Often in cases of inflammatory parenchymal disease, "corticosteroids should be given as infusions of
intravenous methylprednisolone followed by a slowly tapering course of oral steroids". It is suggested that therapy should be continued for a period of time even when the symptoms get suppressed because early relapse may occur. Sometimes, the medical doctors may suggest a different steroid depending on the nature of the disease, the severity, and the response to steroids. According to several studies, parenchymal NBD patients successfully suppress the symptoms with the prescribed steroids. As for non-parenchymal patients, there is no general consensus on how to treat the disease. The reason is that the mechanisms of cerebral venous thrombosis in BD are still poorly understood. Some doctors use anti-coagulants to prevent a clot. On the other hand, some doctors only give steroids and immunosuppressants alone.
Ursodeoxycholic acid has been used successfully as a treatment for cases with liver involvement. Thalidomide has also been tried successfully as a treatment for treatment-resistant lupus pernio in a clinical trial, which may stem from its anti-TNF activity, although it failed to exhibit any efficacy in a pulmonary sarcoidosis clinical trial. Cutaneous disease may be successfully managed with antimalarials (such as chloroquine and hydroxychloroquine) and the tetracycline antibiotic, minocycline. Antimalarials have also demonstrated efficacy in treating sarcoidosis-induced hypercalcemia and neurosarcoidosis. Long-term use of antimalarials is limited, however, by their potential to cause irreversible blindness and hence the need for regular ophthalmologic screening. This toxicity is usually less of a problem with hydroxychloroquine than with chloroquine, although hydroxychloroquine can disturb the glucose homeostasis.
Recently selective phosphodiesterase 4 (PDE4) inhibitors like apremilast (a thalidomide derivative), roflumilast, and the less subtype-selective PDE4 inhibitor, pentoxifylline, have been tried as a treatment for sarcoidosis, with successful results being obtained with apremilast in cutaneous sarcoidosis in a small open-label study. Pentoxifylline has been used successfully to treat acute disease although its use is greatly limited by its gastrointestinal toxicity (mostly nausea, vomiting, and diarrhea). Case reports have supported the efficacy of rituximab, an anti-CD20 monoclonal antibody and a clinical trial investigating atorvastatin as a treatment for sarcoidosis is under-way. ACE inhibitors have been reported to cause remission in cutaneous sarcoidosis and improvement in pulmonary sarcoidosis, including improvement in pulmonary function, remodeling of lung parenchyma and prevention of pulmonary fibrosis in separate case series'. Nicotine patches have been found to possess anti-inflammatory effects in sarcoidosis patients, although whether they had disease-modifying effects requires further investigation. Antimycobacterial treatment (drugs that kill off mycobacteria, the causative agents behind tuberculosis and leprosy) has also proven itself effective in treating chronic cutaneous (that is, it affects the skin) sarcoidosis in one clinical trial. Quercetin has also been tried as a treatment for pulmonary sarcoidosis with some early success in one small trial.
Because of its uncommon nature, the treatment of male reproductive tract sarcoidosis is controversial. Since the differential diagnosis includes testicular cancer, some recommend orchiectomy, even if evidence of sarcoidosis in other organs is present. In the newer approach, testicular, epididymal biopsy and resection of the largest lesion has been proposed.
As the granulomas are caused by collections of immune system cells, particularly T cells, there has been some success using immunosuppressants (like cyclophosphamide, cladribine, chlorambucil, and cyclosporine), immunomodulatory (pentoxifylline and thalidomide), and anti-tumor necrosis factor treatment (such as infliximab, etanercept, golimumab, and adalimumab).
In a clinical trial cyclosporine added to prednisone treatment failed to demonstrate any significant benefit over prednisone alone in people with pulmonary sarcoidosis, although there was evidence of increased toxicity from the addition of cyclosporine to the steroid treatment including infections, malignancies (cancers), hypertension, and kidney dysfunction. Likewise chlorambucil and cyclophosphamide are seldom used in the treatment of sarcoidosis due to their high degree of toxicity, especially their potential for causing malignancies. Infliximab has been used successfully to treat pulmonary sarcoidosis in clinical trials in a number of persons. Etanercept, on the other hand, has failed to demonstrate any significant efficacy in people with uveal sarcoidosis in a couple of clinical trials. Likewise golimumab has failed to show any benefit in persons with pulmonary sarcoidosis. One clinical trial of adalimumab found treatment response in about half of subjects, which is similar to that seen with infliximab, but as adalimumab has better tolerability profile it may be preferred over infliximab.
Corticosteroids remain the main treatment modality for IOI. There is usually a dramatic response to this treatment and is often viewed as pathognomonic for this disease. Although response is usually quick, many agree that corticosteroids should be continued on a tapering basis to avoid breakthrough inflammation.
Although many respond to corticosteroid treatment alone, there are several cases in which adjuvant therapy is needed. While many alternatives are available, there is no particular well-established protocol to guide adjuvant therapy. Among the available options there is: surgery, alternative corticosteroid delivery, radiation therapy, non-steroidal anti-inflammatory drugs, cytotoxic agents (chlorambucil, cyclophosphamide), corticosteroid sparing immunosuppressants (methotrexate, cyclosporine, azathioprine), IV immune-globin, plasmapheresis, and biologic treatments (such as TNF-α inhibitors).
Although the origin of the disease is unknown, there is speculation that it is an aggressive healing response to small tears in the plantar fascia, almost as if the fascia over-repairs itself following an injury. There is also some evidence that it might be genetic.
In the early stages, when the nodule is single and/or smaller, it is recommended to avoid direct pressure to the nodule(s). Soft inner soles on footwear and padding may be helpful.
MRI and sonogram (diagnostic ultrasound) are effective in showing the extent of the lesion, but cannot reveal the tissue composition. Even then, recognition of the imaging characteristics of plantar fibromatoses can help in the clinical diagnosis.
Surgery of Ledderhose's disease is difficult because tendons, nerves, and muscles are located very closely to each other. Additionally, feet have to carry heavy load, and surgery might have unpleasant side effects. If surgery is performed, the biopsy is predominantly cellular and frequently misdiagnosed as fibrosarcoma. Since the diseased area (lesion) is not encapsulated, clinical margins are difficult to define. As such, portions of the diseased tissue may be left in the foot after surgery. Inadequate excision is the leading cause of recurrence.
Radiotherapy has been shown to reduce the size of the nodules and reduce the pain associated with them. It is approximately 80% effective, with minimal side-effects.
Post-surgical radiation treatment may decrease recurrence. There has also been variable success in preventing recurrence by administering gadolinium. Skin grafts have been shown to control recurrence of the disease.
In few cases shock waves also have been reported to at least reduce pain and enable walking again. Currently in the process of FDA approval is the injection of collagenase. Recently successful treatment of Ledderhose with cryosurgery (also called cryotherapy) has been reported.
Cortisone injections, such as Triamcinolone, and clobetasol ointments have been shown to stall the progression of the disease temporarily, although the results are subjective and large-scale studies far from complete. Injections of superoxide dismutase have proven to be unsuccessful in curing the disease while radiotherapy has been used successfully on Ledderhose nodules.
Guidelines for management of patients up to 18 years with Langerhans cell histiocytosis has been suggested. Treatment is guided by extent of disease. Solitary bone lesion may be amenable through excision or limited radiation, dosage of 5-10 Gys for children, 24-30 Gys for adults. However systemic diseases often require chemotherapy. Use of systemic steroid is common, singly or adjunct to chemotherapy. Local steroid cream is applied to skin lesions. Endocrine deficiency often require lifelong supplement e.g. desmopressin for diabetes insipidus which can be applied as nasal drop. Chemotherapeutic agents such as alkylating agents, antimetabolites, vinca alkaloids either singly or in combination can lead to complete remission in diffuse disease.
Systemic corticosteroids such as (prednisone) can produce rapid improvement and are the “gold standard” for treatment. The temperature, white blood cell count, and eruption improve within 72 hours. The skin lesions clear within 3 to 9 days. Abnormal laboratory values rapidly return to normal. There are, however, frequent recurrences. Corticosteroids are tapered within 2 to 6 weeks to zero.
Resolution of the eruption is occasionally followed by milia and scarring. The disease clears spontaneously in some patients. Topical and/or intralesional corticosteroids may be effective as either monotherapy or adjuvant therapy.
Oral potassium iodide or colchicine may induce rapid resolution.
Patients who have a potential systemic infection or in whom corticosteroids are contraindicated can use these agents as a first-line therapy.
In one study, indomethacin, 150 mg per day, was given for the first week, and 100 mg per day was given for 2 additional weeks. Seventeen of 18 patients had a good initial response; fever and arthralgias were markedly attenuated within 48 hours, and eruptions cleared between 7 and 14 days.
Patients whose cutaneous lesions continued to develop were successfully treated with prednisone (1 mg/kg per day). No patient had a relapse after discontinuation of indomethacin.
Other alternatives to corticosteroid treatment include dapsone, doxycycline, clofazimine, and cyclosporine. All of these drugs influence migration and other functions of neutrophils.
Studies on the treatment of cryofibrinoginemic disease have involved relatively few patients, are limited primarily to case reports, and differ based on whether the disease is primary or secondary. In all cases of cryofibrinogenemic disease, however, patients should avoid the exposure of afflicted body parts to cold weather or other environmental triggers of symptoms and avoid using cigarettes or other tobacco products. In severe cases, these individuals also risk developing serious thrombotic events which lead to tissue necrosis that may result in secondary bacterial infections and require intensive antimicrobial therapy and/or amputations. Careful treatment of these developments is required.
Treatment of secondary cryofibrinoginemic disease may use the same methods used for treating the primary disease wherever necessary but focus on treating the associated infectious, malignant, premalignant, vasculitis, or autoimmune disorder with the methods prescribed for the associated disorder. Case report studies suggest that: corticosteroids and immunosuppressive drug regimens, antimicrobial therapy, and anti-neoplastic regimens can be effective treatments for controlling the cryfibrinoginemic disease in cases associated respectively with autoimmune, infectious, and premalignant/malignant disorders.
Physiotherapy
To increase strength of muscle
To improve muscle functions
Electrical modalities =Electric stimulation.etc.
Occupational Therapy
Positioning, ROM, Sensory, Splinting
While pain symptoms may be effectively controlled using medications such as NSAID, amitriptyline, or vitamin B6 supplementation, effective treatment generally requires resolving the underlying cause.
Mild to moderate symptoms, such as pain or paresthesia, are treated conservatively with non-surgical approaches. Physiotherapy treatments can prove effective at treating cubital tunnel syndrome symptoms and can include:
- Joint mobilizations
- Neural flossing/gliding
- Strengthening/stretching exercises
- Activity modification
It is important to identify positions and activities that aggravate symptoms and to find ways to avoid them. For example, if the person experiences symptoms when holding a telephone up to the head, then the use of a telephone headset will provide immediate symptomatic relief and reduce the likelihood of further damage and inflammation to the nerve. For cubital tunnel syndrome, it is recommended to avoid repetitive elbow flexion and also avoiding prolonged elbow flexion during sleep, as this position puts stress of the ulnar nerve.
Surgery is recommended for those who are not improved with conservative therapy or those with serious or progressive symptoms. The surgical approaches vary, and may depend on the location or cause of impingement. Cubital and ulnar tunnel release can be performed wide awake with no general anaesthesia, no regional anaesthesia, no sedation and no tourniquet, and are usually done by Plastic Surgeons
Treatment is indicated when the so-called table top test is positive. With this test, the person places their hand on a table. If the hand lies completely flat on the table, the test is considered negative. If the hand cannot be placed completely flat on the table, leaving a space between the table and a part of the hand as big as the diameter of a ballpoint pen, the test is considered positive and surgery or other treatment may be indicated. Additionally, finger joints may become fixed and rigid.
Treatment involves one or more different types of treatment with some hands needing repeated treatment.
The main categories listed by the International Dupuytren Society in order of stage of disease are radiation therapy, needle aponeurotomy (NA), collagenase injection and hand surgery.
Needle aponeurotomy is most effective at "Stage I and Stage II" of 6–90 degrees of deformation. However, it is also used at other stages.
Collagenase injection is most effective at "Stage I" and Stage II" of 6–90 degrees of deformation. However, it is also used at other stages.
Hand surgery is effective at Stage I – Stage IV.
On June 12, 1831, Dupuytren performed a surgical procedure on a person with contracture of the 4th and 5th digits who had been previously told by other surgeons that the only remedy was cutting the flexor tendons. He described the condition and the operation in "The Lancet" in 1834 after presenting it in 1833 and posthumously in 1836 in a French publication by Hôtel-Dieu de Paris. The procedure he described was a minimally invasive needle procedure.
Because of high recurrence rates, new surgical techniques were introduced, such as fasciectomy and then dermofasciectomy. Most of the diseased tissue is removed with these procedures. For some individuals, the partial insertion of "K wires" into either the DIP or PIP joint of the affected digit for a period of a least 21 days to fuse the joint is the only way to halt the disease's progress. After removal of the wires, the joint is fixed into flexion, which is considered preferable to fusion at extension.
In extreme cases, amputation of fingers may be needed for severe or recurrent cases or after surgical complications.
Acute treatment uses medications to treat any infection (normally antibiotics) and to reduce inflammation (normally aminosalicylate anti-inflammatory drugs and corticosteroids). When symptoms are in remission, treatment enters maintenance, with a goal of avoiding the recurrence of symptoms. Prolonged use of corticosteroids has significant side-effects; as a result, they are, in general, not used for long-term treatment. Alternatives include aminosalicylates alone, though only a minority are able to maintain the treatment, and many require immunosuppressive drugs. It has been also suggested that antibiotics change the enteric flora, and their continuous use may pose the risk of overgrowth with pathogens such as "Clostridium difficile".
Medications used to treat the symptoms of Crohn's disease include 5-aminosalicylic acid (5-ASA) formulations, prednisone, immunomodulators such as azathioprine (given as the prodrug for 6-mercaptopurine), methotrexate, infliximab, adalimumab, certolizumab and natalizumab. Hydrocortisone should be used in severe attacks of Crohn's disease. Biological therapies (biopharmaceuticals) are medications used to avoid long-term steroid use, decrease inflammation, and treat people who have fistulas with abscesses. The monoclonal antibody ustekinumab appears to be a safe treatment option, and may help people with moderate to severe active Crohn's disease. The long term safety and effectiveness of monoclonal antibody treatment is not known. The monoclonal antibody briakinumab is not effective for people with active Crohn's disease.
The gradual loss of blood from the gastrointestinal tract, as well as chronic inflammation, often leads to anemia, and professional guidelines suggest routinely monitoring for this. Adequate disease control usually improves anemia of chronic disease, but iron deficiency may require treatment with iron supplements. Guidelines vary as to how iron should be administered. Besides other, problems include a limitation in possible daily resorption and an increased growth of intestinal bacteria. Some advise parenteral iron as first line as it works faster, has fewer gastrointestinal side effects, and is unaffected by inflammation reducing enteral absorption.
Other guidelines advise oral iron as first line with parenteral iron reserved for those that fail to adequately respond as oral iron is considerably cheaper. All agree that severe anemia (hemoglobin under 10g/dL) should be treated with parenteral iron. Blood transfusion should be reserved for those who are cardiovascularly unstable, due to its relatively poor safety profile, lack of long term efficacy, and cost.
Certain lifestyle changes can reduce symptoms, including dietary adjustments, elemental diet, proper hydration, and smoking cessation. Diets that include higher levels of fiber and fruit are associated with reduced risk, while diets rich in total fats, polyunsaturated fatty acids, meat, and omega-6 fatty acids may increase the risk of Crohn's. Smoking may increase Crohn's disease; stopping is recommended. Eating small meals frequently instead of big meals may also help with a low appetite. To manage symptoms have a balanced diet with proper portion control. Fatigue can be helped with regular exercise, a healthy diet, and enough sleep. A food diary may help with identifying foods that trigger symptoms. Some people should follow a low fiber diet to control acute symptoms especially if fibrous foods cause symptoms. Some find relief in eliminating casein (protein found in cow's milk) and gluten (protein found in wheat, rye and barley) from their diets. They may have specific dietary intolerances (not allergies).
Disease-modifying antirheumatic drugs (DMARDs) are the primary treatment for RA. They are a diverse collection of drugs, grouped by use and convention. They have been found to improve symptoms, decrease joint damage, and improve overall functional abilities. DMARDs should be started early in the disease as they result in disease remission in approximately half of people and improved outcomes overall.
The following drugs are considered as DMARDs: methotrexate, hydroxychloroquine, sulfasalazine, leflunomide, TNF-alpha inhibitors (certolizumab, infliximab and etanercept), abatacept, and anakinra. Rituximab and tocilizumab are monoclonal antibodies and are also DMARDs.
The most commonly used agent is methotrexate with other frequently used agents including sulfasalazine and leflunomide. Sodium aurothiomalate (gold) and cyclosporin are less commonly used due to more common adverse effects. Agents may be used in combinations. Methotrexate is the most important and useful DMARD and is usually the first treatment. Adverse effects should be monitored regularly with toxicity including gastrointestinal, hematologic, pulmonary, and hepatic. Side effects such as nausea, vomiting or abdominal pain can be reduced by taking folic acid.
A 2015 Cochrane review found rituximab with methotrexate to be effective in improving symptoms compared to methotrexate alone. Rituximab works by depicting levels of B-cells (immune cell that is involved in inflammation). People taking rituximab had improved pain, function, reduced disease activity and reduced joint damage based on x-ray images. After 6 months, 21% more people had improvement in their symptoms using rituximab and methotrexate.
Biological agents should generally only be used if methotrexate and other conventional agents are not effective after a trial of three months. They are associated with a higher rate of serious infections as compared to other DMARDs. Biological DMARD agents used to treat rheumatoid arthritis include: tumor necrosis factor alpha (TNFα) blockers such as infliximab; interleukin 1 blockers such as anakinra, monoclonal antibodies against B cells such as rituximab, and tocilizumab T cell co-stimulation blocker such as abatacept. They are often used in combination with either methotrexate or leflunomide. Abatacept should not be used at the same time as other biologics. In those who are well controlled on TNF blockers decreasing the dose does not appear to affect overall function. Persons should be screened for latent tuberculosis before starting any TNF blockers therapy to avoid reactivation.
TNF blockers and methotrexate appear to have similar effectiveness when used alone and better results are obtained when used together. TNF blockers appear to have equivalent effectiveness with etanercept appearing to be the safest. Abatacept appears effective for RA with 20% more people improving with treatment than without but long term safety studies are yet unavailable. However, there is a lack of evidence to distinguish between the biologics available for RA. Issues with the biologics include their high cost and association with infections including tuberculosis.
Excellent for single-focus disease. With multi-focal disease 60% have a chronic course, 30% achieve remission and mortality is up to 10%.
Glucocorticoids can be used in the short term and at the lowest dose possible for flare-ups and while waiting for slow-onset drugs to take effect.
Non-NSAID drugs to relieve pain, like paracetamol may be used to help relieve the pain symptoms; they do not change the underlying disease.
NSAIDs reduce both pain and stiffness in those with RA but do not affect the underlying disease and appear to have no effect on people's long term disease course and thus are no longer first line agents. NSAIDs should be used with caution in those with gastrointestinal, cardiovascular, or kidney problems. Use of methotrexate together with NSAIDS is safe, if adequate monitoring is done. COX-2 inhibitors, such as celecoxib, and NSAIDs are equally effective.
There is no cure for MMA. Treatment consists of muscle strengthening exercises and training in hand coordination. It has been proposed that the changes in this disease are from compression of the spinal cord in flexion due to forward shifting of the posterior dural sac. There have been treatments studies ranging from use of a cervical collar to anterior cervical fusion and posterior decompression.
As with any supplements and drugs, it is best to confer with a veterinarian as to the recommended dosages. Some drugs are not allowed in competition and may need to be withheld a few days before.
Adding potassium and salt to the diet may be beneficial to horses that suffer from recurrent bouts of ER. Horses in hard training may need a vitamin E supplement, as their requirements are higher than horses in more moderate work. The horse may also be deficient in selenium, and need a feed in supplement. Selenium can be dangerous if overfed, so it is best to have a blood test to confirm that the horse is in need of supplemental selenium.
Thyroid hormone supplementation is often beneficial for horses with low thyroid activity (only do so if the horse has been diagnosed with hypothyroidism).
Other drugs that have been used with success include phenytoin, dantrolene, and dimetyl glycine.
Bicarbonate and NSAIDs are of no use in preventing ER.
Although a 2011 research article stated that disagreements between hand surgeons and rheumatologists remain regarding the indications, timing and effectiveness of rheumatoid hand surgery, arthritis mutilans may be successfully treated by iliac-bone graft and arthrodesis of the interphalangeal joints and the metacarpophalangeal joint in each finger.
Biopsy screening although necessary is not mandatory most dentist can visually examine the area and proceed with the proper course of treatment.
Treatment includes:
- Abstention from chewing areca nut (also known as betel nut) and tobacco
- Minimizing consumption of spicy foods, including chiles
- Maintaining proper oral hygiene
- Supplementing the diet with foods rich in vitamins A, B complex, and C and iron
- Forgoing hot fluids like tea, coffee
- Forgoing alcohol
- Employing a dental surgeon to round off sharp teeth and extract third molars
Treatment also includes following:
- The prescription of chewable pellets of hydrocortisone (Efcorlin); one pellet to be chewed every three to four hours for three to four weeks
- 0.5 ml intralesional injection Hyaluronidase 1500 IU mixed in 1 ml of Lignocaine into each buccal mucosa once a week for 4 weeks or more as per condition
- 0.5 ml intralesional injection of Hyaluronidase 1500 IU and 0.5 ml of injection Hydrocortisone acetate 25 mg/ml in each buccal mucosa once a week alternatively for 4 weeks or more as per condition
- Submucosal injections of hydrocortisone 100 mg once or twice daily depending upon the severity of the disease for two to three weeks
- Submucosal injections of human chorionic gonadotrophins (Placentrax) 2-3 ml per sitting twice or thrice in a week for three to four weeks
- Surgical treatment is recommended in cases of progressive fibrosis when interincisor distance becomes less than . (Multiple release incisions deep to mucosa, submucosa and fibrotic tissue and suturing the gap or dehiscence so created by mucosal graft obtained from tongue and Z-plasty. In this procedure multiple deep z-shaped incisions are made into fibrotic tissue and then sutured in a straighter fashion.)
- Pentoxifylline (Trental), a methylxanthine derivative that has vasodilating properties and increases mucosal vascularity, is also recommended as an adjunct therapy in the routine management of oral submucous fibrosis.
- IFN-gamma is antifibrotic cytokine which alters collagen synthesis and helps in OSF.
- Colchicine tablets 0.5 mg twice a day
- Lycopene, 16 mg a day helps in improvement of OSF
The treatment of patients with oral submucous fibrosis depends on the degree of clinical involvement. If the disease is detected at a very early stage, cessation of the habit is sufficient. Most patients with oral submucous fibrosis present with moderate-to-severe disease. Severe oral submucous fibrosis is irreversible. Moderate oral submucous fibrosis is reversible with cessation of habit and mouth opening exercise. Current modern day medical treatments can make the mouth opening to normal minimum levels of 30 mm mouth opening with proper treatment.
Recently scientists have proven that intralesional injection of autologous bone marrow stem cells is a safe and effective treatment modality in oral sub mucosal fibrosis. It has been shown autologous bone marrow stem cell injections induces angiogenesis in the area of lesion which in turn decreases the extent of fibrosis thereby leading to significant increase in mouth opening.
