In severe cases with a high recurrence rate and in HIV-infected patients, thalidomide 100-300 mg/day for 2-3 months may result in complete remission of the ulcers for a long time. However, teratogenesis and polyneuropathy preclude the routine use of thalidomide.
Clinicians should be aware that safe prophylaxis for prevention of recurrences of RAU in the long term is not possible.
Alternative Therapies
In severe cases many other systemic medications have been used with ambiguous results. These include dapsone, levamisole hydrochloride, colchicine, azathioprine, interferon alpha, cyclosporine, pentoxifylline, and recently rebamipide, a gastroprotective drug.

Ariboflavinosis
Definition
Ariboflavinosis or vitamin B2 deficiency is an unusual disorder that usually occurs in combination with other vitamin deficiencies.
Etiology
Deficiency of vitamin B2 occurs due to dietary inadequacy, achlorhydria, malabsorption, alcoholic cirrhosis, hypothyroidism, and drugs.
Main Clinical Features
Oral Manifestations
•Angular cheilitis
•Atrophy of the filiform papillae resulting in a smooth red tongue
•Dry and cracked lips
Other Manifestations
•Skin lesions include perioral seborrheic dermatitis, scaly papules, fissures, and, rarely, ulcers
•Conjunctivitis and photophobia
•Anemia, mental disorders, and slowing of higher functions: weakness may occur
Diagnosis
The diagnosis is based mainly on the medical history and clinical features. Biochemical analysis of vitamin B2 status and measurement of erythrocyte glutathione reductase helps confirm the diagnosis.
Differential Diagnosis
•Pellagra
•Plummer-Vinson syndrome
•Other vitamin B complex deficiencies
•Zinc deficiency
•Angular cheilitis
Treatment
Basic Guidelines
•Improve or treat any underlying illness.
•Eat foods rich in vitamin B2 (meat, fish).
Suggested Therapies
•Treatment consists of riboflavin 5-15 mg/day taken orally until the clinical signs and symptoms are resolved. In severe cases 2-4 mg two times daily can be given parenterally.
•Topical antifungals such as nystatin or miconazole ointment may be used for the treatment of angular cheilitis.
•A high level of oral hygiene is necessary.

Aspergillosis
Definition
Aspergillosis is an opportunistic fungal infection with a broad spectrum of clinical manifestations.
Etiology
Aspergillus fumigatus and A. flavus are the main pathogenic Aspergillus species. Immunocompromised patients such as those with HIV infection, neutropenia, leukemia, and diabetes, those receiving immunosuppressant agents and organ transplantation, and patients with chronic respiratory diseases are more susceptible to Aspergillus infection.
Classification
There are several types of Aspergillus infection: a) allergic aspergillosis, b) aspergilloma (fungus balls), c) invasive aspergillosis (pulmonary involvement in 90-95% and extrapulmonary involvement in 20-25%), d) chronic necrotizing pulmonary aspergillosis, and e) superficial aspergillosis with skin, ear, and eye involvement.
