Medical uses
Vitamin B12 deficiency
Standard therapy for treatment of vitamin B12 deficiency has been intramuscular (IM) or intravenous (IV) injections of hydroxocobalamin (OHCbl), since the majority of cases are due to malabsorption by the enteral route (gut). It is used pediatric patients with intrinsic cobalamin metabolic diseases, vitamin B12-deficient patients with tobacco amblyopia due to cyanide poisoning, and patients with pernicious anemia who have optic neuropathy.In a newly diagnosed vitamin B12-deficient patient, normally defined as when serum levels are less than 200 pg/ml, daily IM injections of hydroxocobalamin up to 1,000 μg (1 mg) per day are given to replenish the bodys depleted cobalamin stores.
In herpetic gingivostomatitis, lesions can be found in these locations, but they are almost always accompanied by ulcerations on the gums, lips, tongue or buccal mucosa and/or by hyperemia, hypertrophy or hemorrhage of the gums. Hand Foot and Mouth Disease: Similar to herpangina, hand foot and mouth disease occurs predominantly in children. It is caused by Coxsackie A and B virus, and lesions or blisters are found bilaterally on the hands, feet and mouth of the patient. Oral candidiasis: Also known as thrush, herpetic gingivostomatitis can often be differentiated from these microorganism/bacterial causing white plaques on the palate, buccal mucosa, tongue, oropharynx etc. Apthous stomatitis: They are commonly known as apthous ulcers, and are characterized by grey membranes and peripheral erythema. Lesions/ulcers for herpetic gingivostomatitis may also be found on the palate and keratinzied gingivae hence aphthous ulcers can be ruled out. Stevens–Johnson syndrome: Stevens–Johnson syndrome is characterized by early symptoms of malaise and fever, and shortly after that erythema, purpura and plaques on the skin, which often progresses to epidermal necrosis and sloughing in extreme cases. Infectious mononucleosis - Infectious Mononucleosis presents with a high fever and lymphadenopathy, which is may or may not be presented in the symptoms of herpetic gingivostomatitis. However, upon closer oral examination, ulceration, petechiae and occasional gingivostomatitis may be spotted. Behcets syndrome - It is an inflammatory disorder in which the presenting symptoms are recurrent aphthous ulcers, and severe cases may result in the patient having genital lesions, gastro-intestinal problems, and even arthritis.
