Diabetic foot ulcers develop their own, distinctive microbiota. Investigations into characterizing and identifying the phyla, genera and species of nonpathogenic bacteria or other microorganisms populating these ulcers may help identify one group of microbiota that promotes healing.The recent advances in epigenetic modifications, with special focus on aberrant macrophage polarisation is giving increasing evidences that epigenetic modifications might play a vital role in changing the treatment of diabetic foot ulcer in the near future.

Bowel-associated dermatosis–arthritis syndrome (BADAS), is a complication of jejunoileal bypass surgery consisting of flu-like symptoms (fever, malaise), multiple painful joints (polyarthralgia), muscle aches (myalgia) and skin changes. It has been reported to occur in up to 20% of patients who had jejunoileal bypass surgery, a form of obesity surgery that is rarely performed today.An excessive immune response to gut bacteria is thought to cause BADAS. Antibiotics have been used successfully to treat the condition (including tetracyclines, macrolides, metronidazole and fluoroquinolones). Corticosteroids are an alternative. Surgical repair of the normal bowel transit, where possible, can be effective. BADAS has later been reported in patients with inflammatory bowel disease, diverticulitis and following resection of the stomach (gastrectomy). BADAS has also been reported following biliopancreatic diversion (a form of bariatric surgery, also known as Scopinaro procedure), and in one case, BADAS occurred in a patient with acute appendicitis. Since "bowel bypass syndrome" is not applicable to these cases, the term BADAS was coined by Jorizzo and co-authors in 1984. Symptoms and signs
The most typical skin changes are a red patch (erythematous macula) with a central vesicle or pustule that heals without scarring. This maculopapular rash can recur every 4–6 weeks and predominantly affect the upper chest and arms. Erythema nodosum-like skin lesions can affect the legs. When a skin biopsy is examined under the microscope, there can be signs of a neutrophilic dermatosis. The joint pains in BADAS are typically episodic, migratory and affecting multiple joints. They can affect the small joints (e.g.
