Digital dermatitis is a polymicrobial disease involving treponemes and other anaerobes. Treponemes are the bacterium most commonly found in lesions. Their abundance increases as the lesion progresses. They account for 94% of bacterial sequences detected in chronic lesions.

Treatment of lesions of digital dermatitis is done by topical application of agents to the affected skin. The skin should be cleaned and kept dry prior treatment. Topical oxytetracycline (OTC) is often referred as the most reliable treatment as cows treated with OTC have a good recovery rate. Bandaging the lesion is often undertaken but there is no evidence of any benefit and bandaging can provide the anaerobic environment which supports the spirochaetes.. Systemic antibiotics are not needed.

Control and prevention of digital dermatitis relies on prompt detection, isolation and treatment of affected cattle. Group hoof disinfection can be achieved via the passage of the cows through footbaths of antimicrobial solutions. Slurry build-up should be avoided since organic matter can impair the antimicrobial efficacy of the footbath solutions. Regular footbaths should be organised, using formalin, copper sulphate or a thymol-based disinfectant. While regular footbathing can help prevent hoof infections, occasional flare-up of active M2 lesions can happen.

The skin should be cleaned and kept dry, and topical antibiotics can be applied to the area. Systemic antibiotics are not needed.

Control relies on prompt detection, isolation and treatment of affected cattle. Footpaths should be kept as dry as possible and slurry build-up should be avoided. Regular footbaths should be organised, using formalin, copper sulphate or a thymol-based disinfectant. In 2013, a safer and alternative to chemicals for hoof baths called Thymox Technology was proven, through field testing, to kill the main bacteria causing digital dermatitis.

Interdigital dermatitis appears as an infections of the skin between the claws and is usually very mild. There may be fluid or a scab in that area, and there is rarely lameness. There is then progression to the heels which become raw and cattle will experience pain. Chronic cases will show changes of the hoof including hyperplasia of the interdigital tissues and muscle atrophy in the affected limb. The horn may become underrun.

Diagnosis is principally based on history and clinical signs. It is very rare that attempts are made to isolate the bacteria.

Diagnosis may include careful identification of the cause with the aid of a good patient history, swabs and cultures, and pathological examination of a biopsy.

The medieval "Bald's Leechbook" recommended treating chilblains with a mix of eggs, wine, and fennel root.

A common tradition of Hispanic America recommends warm garlic on the chilblains.

Initial treatment in adults often involves simply pulling back the foreskin and cleaning the penis.

Chilblains — also known as pernio, chill burns and perniosis — is a medical condition that occurs when a predisposed individual is exposed to cold and humidity, causing tissue damage. It is often confused with frostbite and trench foot. Damage to capillary beds in the skin causes redness, itching, inflammation, and sometimes blisters. Chilblains can be reduced by keeping the feet and hands warm in cold weather, and avoiding extreme temperature changes. Chilblains can be idiopathic (spontaneous and unrelated to another disease), but may also be a manifestation of another serious medical condition that must be investigated. A history of chilblains suggests a connective tissue disease (such as lupus). In infants, chilblains together with severe neurologic disease and unexplained fevers occurs in Aicardi–Goutières syndrome, a rare inherited condition.

Because of the number of possible viral/bacterial precursors to BRD, there are a number of treatment options circling around the three main aggravators of the disease: Viruses, Bacteria, and Stress.

Dupuytren’s disease has a high recurrence rate, especially when a person has so called Dupuytren’s diathesis. The term diathesis relates to certain features of Dupuytren's disease and indicates an aggressive course of disease.

The presence of all new Dupuytren’s diathesis factors increases the risk of recurrent Dupuytren’s disease by 71% compared with a baseline risk of 23% in people lacking the factors. In another study the prognostic value of diathesis was evaluated. They concluded that presence of diathesis can predict recurrence and extension. A scoring system was made to evaluate the risk of recurrence and extension evaluating the following values: bilateral hand involvement, little finger surgery, early onset of disease, plantar fibrosis, knuckle pads and radial side involvement.

Minimally invasive therapies may precede higher recurrence rates. Recurrence lacks a consensus definition. Furthermore, different standards and measurements follow from the various definitions.

The bacteria invade the lacrimal glands of the eye, causing keratitis, uveitis, and corneal ulceration. Cattle show signs of pain, increased lacrimation, excessive blinking, and conjunctivitis. More severe cases may show systemic signs such as anorexia and weight loss. Chronic untreated cases can become blind. Diagnosis is usually based on the clinical signs, but the bacteria can be cultured from lacrimal swabs, or visualised on smears of lacrimal secretions.

Shade, insect repellent-impregnated ear tags, and lower stocking rates may help prevent IBK. Early identification of the disease also helps prevent spread throughout the herd. Treatment is with early systemic use of a long-acting antibiotic such as tetracycline or florfenicol. Subconjunctival injections with procaine penicillin or other antibiotics are also effective, providing a "bubble" of antibiotic which releases into the eye slowly over several days.

Anti-inflammatory therapy can help shorten recovery times, but topical corticosteroids should be used with care if corneal ulcers are present.

"M. bovis" uses several different serotyped fimbriae as virulence factors, consequently pharmaceutical companies have exploited this to create vaccines. However, currently available vaccines are not reliable.

In the absence of vaccination (often because calves are bought unvaccinated), antibiotics can help to stop the bacterial factors of the disease. The Virginia Cooperative Extension recommends Micotil, Nuflor, and Baytril 100 as newer antibiotics that do not need daily dosing, but also notes that Naxcel, Excenel, and Adspec are effective as well.

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

Viral arthritis is an infectious condition in chickens and to a lesser extent, turkeys, due to a reovirus.

The disease is egg-transmitted.

The prominent symptom is a swelling of digital flexor and metatarsal extensor tendons. The hock joint itself is not so sharply affected, showing just a small amount of synovial exsudate when opened.

CREST is not easily diagnosed as it closely mimics symptoms of other connective tissue and autoimmune diseases. Diagnoses are usually given when a patient presents three or more of the five major clinical symptoms. Additionally, blood exams can be given to test for a positive ANAs and ACAs or skin biopsies can be given to help confirm a diagnosis.

CREST syndrome can be noted in up to 10% of patients with primary biliary cirrhosis.

Acral fibrokeratoma (also known as an "Acquired digital fibrokeratoma," and "Acquired periungual fibrokeratoma") is a skin lesion characterized by a pinkish, hyperkeratotic, hornlike projection occurring on a finger, toe, or palm.

The natural history of disease for trigger finger remains uncertain.

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

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

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

No specific work up is defined. Stenosing tenosynovitis is a clinical diagnosis. However, if rheumatoid arthritis is suspected, laboratory evaluation of is granted (e.g. rheumatoid factor). Imaging studies are not needed to diagnose the condition. However, they can be valuable adjuvants to achieve a diagnosis. An ultrasound or MRI ( the most reliable study) can demonstrate increased thickness of the involved tendons. Thickening and hyper-vascularization of the pulley are the hallmarks of trigger fingers on sonography.

Subungual hematomas are treated by either releasing the pressure conservatively when tolerable or by drilling a hole through the nail into the hematoma (trephining), or by removing the entire nail. Trephining is generally accomplished by using a heated instrument to pass through the nail into the blood clot. Removal of the nail is typically done when the nail itself is disrupted, a large laceration requiring suturing is suspected, or a fracture of the tip of the finger occurs. Although general anesthesia is generally not required, a digital nerve block is recommended to be performed if the nail is to be removed.

Subungual hematomas typically heal without incident, though infection or disruption of the nail (onycholysis) may occur.

Diagnosis of BMCF depends on a combination of history and symptoms, histopathology and detection in the blood or tissues of viral antibodies by ELISA or of viral DNA by PCR. The characteristic histologic lesions of MCF are lymphocytic arteritis with necrosis of the blood vessel wall and the presence of large T lymphocytes mixed with other cells. The similarity of MCF clinical signs to other enteric diseases, for example blue tongue, mucosal disease and foot and mouth make laboratory diagnosis of MCF important. The world organisation for animal health recognises histopathology as the definitive diagnostic test, but laboratories have adopted other approaches with recent developments in molecular virology. No vaccine has as yet been developed.

Diagnosis is made almost exclusively by history and physical examination alone. More than one finger may be affected at a time, though it usually affects the index, thumb, middle, or ring finger. The triggering is usually more pronounced late at night and into the morning, or while gripping an object firmly.

Lesions of paravaccinia virus will clear up with little to no scaring after 4 to 8 weeks. An antibiotic may be prescribed by a physician to help prevent bacterial infection of the lesion area. In rare cases, surgical removal of the lesions can be done to help increase rate of healing, and help minimize risk of bacterial or fungal infection. Upon healing, no long term side effects have been reported.

Doctors uses a variety of tools and techniques to evaluate the type of anorectal disorder, including digital and anoscopic investigations, palpations, and palpitations. The initial examination can be painful because a gastroenterologist will need to spread the buttocks and probe the painful area, which may require a local anesthetic.
