Incision drainage with proper evacuation of the fluid followed by anti-tubercular medication.

Treatment involves antibiotics and may involve drainage of the buboes or abscesses by needle aspiration or incision. Further supportive measure may need to be taken: dilatation of the rectal stricture, repair of rectovaginal fistulae, or colostomy for rectal obstruction.

Common antibiotic treatments include: tetracycline (doxycycline) (all tetracyclines, including doxycycline, are contraindicated during pregnancy and in children due to effects on bone development and tooth discoloration), and erythromycin. Azithromycin is also a drug of choice in LGV.

As with all STIs, sex partners of patients who have LGV should be examined and tested for urethral or cervical chlamydial infection. After a positive culture for chlamydia, clinical suspicion should be confirmed with testing to distinguish serotype. Antibiotic treatment should be started if they had sexual contact with the patient during the 30 days preceding onset of symptoms in the patient. Patients with a sexually transmitted disease should be tested for other STDs due to high rates of comorbid infections. Antibiotics are not without risks and prophylaxtic broad antibiotic coverage is not recommended.

Pain medication such as NSAIDs and paracetamol (acetaminophen) helps in the management of pain associated with strep throat. Viscous lidocaine may also be useful. While steroids may help with the pain, they are not routinely recommended. Aspirin may be used in adults but is not recommended in children due to the risk of Reye syndrome.

People with AIDS are given macrolide antibiotics such as azithromycin for prophylactic treatment.

People with HIV infection and less than 50 CD4+ T-lymphocytes/uL should be administered prophylaxis against MAC. Prophylaxis should be continued for the patient's lifetime unless multiple drug therapy for MAC becomes necessary because of the development of MAC disease.

Clinicians must weigh the potential benefits of MAC prophylaxis against the potential for toxicities and drug interactions, the cost, the potential to produce resistance in a community with a high rate of tuberculosis, and the possibility that the addition of another drug to the medical regimen may adversely affect patients' compliance with treatment. Because of these concerns, therefore, in some situations rifabutin prophylaxis should not be administered.

Before prophylaxis is administered, patients should be assessed to ensure that they do not have active disease due to MAC, M. tuberculosis, or any other mycobacterial species. This assessment may include a chest radiograph and tuberculin skin test.

Rifabutin, by mouth daily, is recommended for the people's lifetime unless disseminated MAC develops, which would then require multiple drug therapy. Although other drugs, such as azithromycin and clarithromycin, have laboratory and clinical activity against MAC, none has been shown in a prospective, controlled trial to be effective and safe for prophylaxis. Thus, in the absence of data, no other regimen can be recommended at this time.The 300-mg dose of rifabutin has been well tolerated. Adverse effects included neutropenia, thrombocytopenia, rash, and gastrointestinal disturbances.

Untreated streptococcal pharyngitis usually resolves within a few days. Treatment with antibiotics shortens the duration of the acute illness by about 16 hours. The primary reason for treatment with antibiotics is to reduce the risk of complications such as rheumatic fever and retropharyngeal abscesses; antibiotics are effective if given within 9 days of the onset of symptoms.

It is not lethal in nature and is responsive to tetracycline or ciprofloxacin. Surgical treatment include rhinoplasty. However, if left untreated the disease can lead to sepsis, bleeding, or other chronic conditions that can be fatal.

Postinfection treatment involves a combination of antituberculosis antibiotics, including rifampicin, rifabutin, ciprofloxacin, amikacin, ethambutol, streptomycin, clarithromycin or azithromycin.

NTM infections are usually treated with a three-drug regimen of either clarithromycin or azithromycin, plus rifampicin and ethambutol. Treatment typically lasts at least 12 months.

Although studies have not yet identified an optimal regimen or confirmed that any therapeutic regimen produces sustained clinical benefit for patients with disseminated MAC, the Task Force concluded that the available information indicated the need for treatment of disseminated MAC. The Public Health Service therefore recommends that regimens be based on the following principles:

- Treatment regimens outside a clinical trial should include at least two agents.

- Every regimen should contain either azithromycin or clarithromycin; many experts prefer ethambutol as a second drug. Many clinicians have added one or more of the following as second, third, or fourth agents: clofazimine, rifabutin, rifampin, ciprofloxacin, and in some situations amikacin. Isoniazid and pyrazinamide are not effective for the therapy of MAC.

- Therapy should continue for the lifetime of the patient if clinical and microbiologic improvement is observed.

Clinical manifestations of disseminated MAC—such as fever, weight loss, and night sweats—should be monitored several times during the initial weeks of therapy. Microbiologic response, as assessed by blood culture every 4 weeks during initial therapy, can also be helpful in interpreting the efficacy of a therapeutic regimen.Most patients who ultimately respond show substantial clinical improvement in the first 4–6 weeks of therapy. Elimination of the organisms from blood cultures may take somewhat longer, often requiring 4–12 weeks.

No specific cure is known. Treatment is largely supportive. Nonsteroidal anti-inflammatory drugs (NSAIDs) are indicated for tender lymph nodes and fever, and corticosteroids are useful in severe extranodal or generalized disease.

Symptomatic measures aimed at relieving the distressing local and systemic complaints have been described as the main line of management of KFD. Analgesics, antipyretics, NSAIDs, and corticosteroids have been used. If the clinical course is more severe, with multiple flares of bulky enlarged cervical lymph nodes and fever, then a low-dose corticosteroid treatment has been suggested.

Sulfonamides are the traditional remedies to paracoccidiodomycosis. They were introduced by Oliveira Ribeiro and used for more than 50 years with good results. The most-used sulfa drugs in this infection are sulfadimethoxime, sulfadiazine, and co-trimoxazole. This treatment is generally safe, but several adverse effects can appear, the most severe of which are the Stevens-Johnson syndrome and agranulocytosis. Similarly to tuberculosis treatment, it must be continued for up to three years to eradicate the fungus, and relapse and treatment failures are not unusual.

Antifungal drugs such as amphotericin B or itraconazole and ketoconazole are more effective in clearing the infection, but are limited by their cost when compared with sulfonamides.During therapy, fibrosis can appear and surgery may be needed to correct this. Another possible complication is Addisonian crisis. The mortality rate in children is around 7-10%.

Some current treatment options are:

- Non-invasive:

- For small stones, hydration, moist heat therapy, NSAIDs (nonsteroidal anti-inflammatory drugs) occasionally, and having the patient take any food or beverage that is bitter and/or sour. Sucking on citrus fruits, such as a lemon or orange, may increase salivation and promote spontaneous expulsion of the stone.

- Some stones may be massaged out by a specialist.

- Shock wave therapy (Extracorporeal shock wave lithotripsy).

- Minimally invasive:

- Sialendoscopy

- Surgical:

- An ENT or oral/maxillofacial surgeon may cannulate the duct to remove the stone (sialectomy).

- A surgeon may make a small incision near the stone to remove it.

- In some cases when stones continually reoccur the offending salivary duct is removed.

- Supporting treatment:

- To prevent infection while the stone is lodged in the duct, antibiotics are sometimes used.

The treatment in viral or idiopathic pericarditis is with aspirin, or non-steroidal anti-inflammatory drugs (NSAIDs such as ibuprofen). Colchicine may be added to the above as it decreases the risk of further episodes of pericarditis.

Severe cases may require one or more of the following:

- pericardiocentesis to treat pericardial effusion/tamponade

- antibiotics to treat tuberculosis or other bacterial causes.

- steroids are used in acute pericarditis but are not favored because they increase the chance of recurrent pericarditis.

- in rare cases, surgery

- in cases of constrictive pericarditis, pericardiectomy

An important factor is whether the involved tooth is to be extracted or retained. Although the pulp is usually still vital, a history of recurrent periodontal abscesses and significantly compromised periodontal support indicate that the prognosis for the tooth is poor and it should be removed.

The initial management of a periodontal abscess involves pain relief and control of the infection. The pus needs to be drained, which helps both of these aims. If the tooth is to be removed, drainage will occur via the socket. Otherwise, if pus is already discharging from the periodontal pocket, this can be encouraged by gentle irrigation and scaling of the pocket whilst massaging the soft tissues. If this does not work, incision and drainage is required, as described in Dental abscess#Treatment.

Antibiotics are of secondary importance to drainage, which if satisfactory renders antibiotics unnecessary. Antibiotics are generally reserved for severe infections, in which there is facial swelling, systemic upset and elevated temperature. Since periodontal abscesses frequently involve anaerobic bacteria, oral antibiotics such as amoxicillin, clindamycin (in penicillin allergy or pregnancy) and/or metronidazole are given. Ideally, the choice of antibiotic is dictated by the results of microbiological culture and sensitivity testing of a sample of the pus aspirated at the start of any treatment, but this rarely occurs outside the hospital setting.

Other measures that are taken during management of the acute phase might include reducing the height of the tooth with a dental drill, so it no longer contacts the opposing tooth when biting down; and regular use of hot salt water mouth washes (antiseptic and encourages further drainage of the infection).

The management following the acute phase involves removing any residual infection, and correcting the factors that lead to the formation of the periodontal abscess. Usually, this will be therapy for periodontal disease, such as oral hygiene instruction and periodontal scaling.

Rhinoscleroma, or simply scleroma, is a chronic granulomatous bacterial disease of the nose that can sometimes infect the upper respiratory tract. It most commonly affects the nasal cavity—the nose is involved in 95–100 per cent of cases—however, it can also affect the nasopharynx, larynx, trachea, and bronchi. Slightly more females than males are affected and patients are usually 10 to 30 years of age. Rhinoscleroma is considered a tropical disease and is mostly endemic to Africa and Central America, less common in the United States.

Treatment includes fluid intake, good oral hygiene and gentle debridement of the mouth, as well as oral acyclovir. In healthy individuals the lesions heal spontaneously in 7–14 days without scarring.

Low-level laser therapy (LLLT) was cleared by the US Food and Drug Administration (FDA) for the treatment of lymphedema in November 2006.

According to the US National Cancer Institute,

Studies suggest that low-level laser therapy may be effective in reducing lymphedema in a clinically meaningful way for some women. Two cycles of laser treatment were found to be effective in reducing the volume of the affected arm, extracellular fluid, and tissue hardness in approximately one-third of patients with postmastectomy lymphedema at 3 months post-treatment. Suggested rationales for laser therapy include a potential decrease in fibrosis, stimulation of macrophages and the immune system, and a possible role in encouraging lymphangiogenesis.

"Lymph adenitis" or "lymph node adenitis" is caused by infection in lymph nodes. The infected lymph nodes typically become enlarged, warm and tender. A swelling of lymph nodes due to growth of lymph cells is called lymphadenopathy. Types include:

- Neck

- Cervical adenitis is an inflammation of a lymph node in the neck.

- Tuberculous adenitis (scrofula) is a tuberculous infection of the skin of the neck caused by "Mycobacterium tuberculosis". Non-tuberculous adenitis can also be caused by "Mycobacterium scrofulaceum" or "Mycobacterium avium".

- Abdomen

- Mesenteric adenitis is an inflammation of the mesenteric lymph nodes in the abdomen. It can be caused by the bacterium "Yersinia enterocolitica". If it occurs in the right lower quadrant, it can be mistaken for acute appendicitis, often preceded by a sore throat.

When possible, immediate definitive treatment of acute pericoronitis is recommended because surgical treatment has been shown to resolve the spread of the infection and pain, with a quicker return of function. Also immediate treatment avoids overuse of antibiotics (preventing antibiotic resistance).

However, surgery is sometimes delayed in an area of acute infection, with the help of pain relief and antibiotics, for the following reasons:

- Reduces the risk of causing an infected surgical site with delayed healing (e.g. osteomyelitis or cellulitis).

- Avoids reduced efficiency of local anesthetics caused by the acidic environment of infected tissues.

- Resolves the limited mouth opening, making oral surgery easier.

- Patients may better cope with the dental treatment when free from pain.

- Allows for adequate planning with correctly allocated procedure time.

Firstly, the area underneath the operculum is gently irrigated to remove debris and inflammatory exudate. Often warm saline is used but other solutions may contain hydrogen peroxide, chlorhexidine or other antiseptics. Irrigation may be assisted in conjunction with Debridement (removal of plaque, calculus and food debris) with periodontal instruments. Irrigation may be enough to relieve any associated pericoronal abscess; otherwise a small incision can be made to allow drainage.

Smoothing an opposing tooth which bites into the affected operculum can eliminate this source of trauma.

Home care may involve regular use of hot salt water mouthwashes/mouth baths.

Following treatment, if there are systemic signs and symptoms, such as facial or neck swelling, cervical lymphadenitis, fever or malaise, a course of oral antibiotics is often prescribed. Common antibiotics used are from the β-lactam antibiotic group, clindamycin and metronidazole.

If there is dysphagia or dyspnoea (difficulty swallowing or breathing), then this usually means there is a severe infection and an emergency admission to hospital is appropriate so that intravenous medications and fluids can be administered and the threat to the airway monitored. Sometimes semi-emergency surgery may be arranged to drain a swelling that is threatening the airway.

Adenitis is a general term for an inflammation of a gland. Often it is used to refer to lymphadenitis which is the inflammation of a lymph node.

Since pericoronitis is a result of inflammation of the pericoronal tissues of a partially erupted tooth, management can include applying pain management gels for the mouth consisting of Lignocaine, a numbing agent. Definitive treatment can only be through preventing the source of inflammation. This is either through improved oral hygiene or by removal of the plaque stagnation areas through tooth extraction or gingival resection. Often acute symptoms of pericoronitis are treated before the underlying cause is addressed.

Lymph node enlargement is recognized as a common sign of infectious, autoimmune, or malignant disease. Examples may include:

- Reactive: acute infection ("e.g.," bacterial, or viral), or chronic infections (tuberculous lymphadenitis, cat-scratch disease).

- The most distinctive sign of bubonic plague is extreme swelling of one or more lymph nodes that bulge out of the skin as "buboes." The buboes often become necrotic and may even rupture.

- Infectious mononucleosis is an acute viral infection caused by Epstein-Barr virus and may be characterized by a marked enlargement of the cervical lymph nodes.

- It is also a sign of cutaneous anthrax and Human African trypanosomiasis

- Toxoplasmosis, a parasitic disease, gives a generalized lymphadenopathy ("Piringer-Kuchinka lymphadenopathy").

- Plasma cell variant of Castleman's disease - associated with HHV-8 infection and HIV infection

- Mesenteric lymphadenitis after viral systemic infection (particularly in the GALT in the appendix) can commonly present like appendicitis.

Less common infectious causes of lymphadenopathy may include bacterial infections such as cat scratch disease, tularemia, brucellosis, or prevotella.

- Tumoral:

- Primary: Hodgkin lymphoma and non-Hodgkin lymphoma give lymphadenopathy in all or a few lymph nodes.

- Secondary: metastasis, Virchow's Node, neuroblastoma, and chronic lymphocytic leukemia.

- Autoimmune: systemic lupus erythematosus and rheumatoid arthritis may have a generalized lymphadenopathy.

- Immunocompromised: AIDS. Generalized lymphadenopathy is an early sign of infection with human immunodeficiency virus (HIV), the virus that causes acquired immunodeficiency syndrome (AIDS). "Lymphadenopathy syndrome" has been used to describe the first symptomatic stage of HIV progression, preceding a diagnosis of AIDS.

- Bites from certain venomous snakes such as the pit viper

- Unknown: Kikuchi disease, progressive transformation of germinal centers, sarcoidosis, hyaline-vascular variant of Castleman's disease, Rosai-Dorfman disease, Kawasaki disease, Kimura disease

Lymphangitis is an inflammation or an infection of the lymphatic channels that occurs as a result of infection at a site distal to the channel. The most common cause of lymphangitis in humans is "Streptococcus pyogenes" (Group A strep), although it can also be caused by the fungus "Sporothrix schenckii". Lymphangitis is sometimes mistakenly called "blood poisoning". In reality, "blood poisoning" is synonymous with "sepsis".

Signs and symptoms include a deep reddening of the skin, warmth, lymphadenitis (inflammation of a lymphatic gland), and a raised border around the affected area. The person may also have chills and a high fever along with moderate pain and swelling. A person with lymphangitis should be hospitalized and closely monitored by medical professionals.

Lymphangitis is the inflammation of the lymphatic vessels and channels. This is characterized by certain inflammatory conditions of the skin caused by bacterial infections. Thin red lines may be observed running along the course of the lymphatic vessels in the affected area, accompanied by painful enlargement of the nearby lymph nodes.

When the inferior limbs are affected, the redness of the skin runs over the great saphenous vein location and confusion can be made with a thrombophlebitis.

Chronic lymphangitis is a cutaneous condition that is the result of recurrent bouts of acute bacterial lymphangitis.

With advanced microsurgical techniques, lymph vessels can be used as grafts. A locally interrupted or obstructed lymphatic pathway, mostly after resection of lymph nodes, can be reconstructed via a bypass using lymphatic vessels. These vessels are specialized to drain lymph by active pumping forces. These grafts are connected with main lymphatic collectors in front and behind the obstruction. The technique is mostly used in arm edemas after treatment of breast cancer and in unilateral edemas of lower extremities after resection of lymph nodes and radiation. The procedure is less widely used than the other surgical procedures, mainly in Germany. The method was developed in 1980 by Ruediger Baumeister.

The method is proven effective. Follow-up studies showed significant volume reduction of the extremities even 10 years after surgery. The patients, who had been previously treated with both MLD and compression therapy, gained significant improvement in quality of life after being treated with lymphatic vessel grafting. Lymphoscintigraphic investigations showed a lasting enhancement of lymphatic transport after grafting.

The patency of lymphatic grafts was demonstrated after more than 12 years, using indirect lymphography and MRI lymphography.

Tuberculous lymphadenitis (or tuberculous adenitis) is a chronic specific granulomatous inflammation of the lymph node with caseation necrosis, caused by infection with "Mycobacterium tuberculosis" or "Mycobacterium bovis".

The characteristic morphological element is the tuberculous granuloma (caseating tubercule). This consists of giant multinucleated cells and (Langhans cells), surrounded by epithelioid cells aggregates, T cell lymphocytes and fibroblasts. Granulomatous tubercules eventually develop central caseous necrosis and tend to become confluent, replacing the lymphoid tissue.

Lymphadenopathy or adenopathy is disease of the lymph nodes, in which they are abnormal in size, number, or consistency. Lymphadenopathy of an inflammatory type (the most common type) is lymphadenitis, producing swollen or enlarged lymph nodes. In clinical practice, the distinction between lymphadenopathy and lymphadenitis is rarely made and the words are usually treated as synonymous. Inflammation of the lymphatic vessels is known as lymphangitis. Infectious lymphadenitides affecting lymph nodes in the neck are often called scrofula.

The term comes from the word lymph and a combination of the Greek words , "adenas" ("gland") and , "patheia" ("act of suffering" or "disease").

Lymphadenopathy is a common and nonspecific sign. Common causes include infections (from minor ones such as the common cold to dangerous ones such as HIV/AIDS), autoimmune diseases, and cancers. Lymphadenopathy is also frequently idiopathic and self-limiting.
