Topical and systemic therapy for recurrent aphthous stomatitis.

The cause of recurrent aphthous ulcers (RAU), the lesions of recurrent aphthous stomatitis, is incompletely understood but appears to involve immune system dysfunction. Treatment options include no treatment, treatment of associated systemic diseases or conditions (eg, celiac sprue, vitamin deficiencies), systemic medications, topical medications, conversion of the aphthous ulcer to a wound, and palliative treatments. The most effective treatments (systemic or topical corticosteroids, thalidomide) involve agents that suppress or modulate immune system function. In general, topical agents are preferred because they have fewer associated side effects; however, inability to obtain adequate contact time may limit their effectiveness. Adjunct pain control is sometimes necessary, either with pain medications or with adherent agents that coat the ulcers.

Confluent ecchymoses on the lower extremities of a malnourished patient.

Nutritional deficiencies result in many distinctive cutaneous manifestations. Vitamin C deficiency, or scurvy, produces follicular hyperkeratosis, perifollicular hemorrhages, gingival hypertrophy, and bleeding (1). We report here a case of malnutrition who suddenly developed extensive eccymoses on the lower extremities sharing morphological similarities with purpura fulminans. Although the patient did not have the characteristic dermatological features of scurvy, serum levels of vitamins C, K, B12, and E were decreased.

[Scurvy, a serious and rare form of avitaminosis, easily diagnosed and treated. Presentation of a case]. / Escorbuto, una grave y rara avitaminosis de fácil diagnóstico y tratamiento. Presentación de un caso.

We report a 66 years-old man case that was admitted with abdominal wall hemorrhagic swelling ecchymosis on inferior extremities and perifollicular purpura with hyperkeratosis of the follicles, which gives it an appearance of palpable purpura, together with gingival hemorrhage and moderate anemia. He was a well-nourished sick man but who made a peculiar diet, practically free from fruit and vegetables which developed a pure and serious form of scurvy. We report this case because we consider that the features which appear are illustrative to provide the immediate clinical diagnosis of this uncommon disease, potentially mortal, but easy to diagnose, if we think about it in the adequate clinical contexts, and which it is quickly curable with the administration of ascorbic acid.

Efficacy of fat-soluble vitamin supplementation in infants with biliary atresia.

OBJECTIVE: Cholestasis predisposes to fat-soluble vitamin (FSV) deficiencies. A liquid multiple FSV preparation made with tocopheryl polyethylene glycol-1000 succinate (TPGS) is frequently used in infants with biliary atresia (BA) because of ease of administration and presumed efficacy. In this prospective multicenter study, we assessed the prevalence of FSV deficiency in infants with BA who received this FSV/TPGS preparation. METHODS: Infants received FSV/TPGS coadministered with additional vitamin K as routine clinical care in a randomized double-blinded, placebo-controlled trial of corticosteroid therapy after hepatoportoenterostomy (HPE) for BA (identifier NCT 00294684). Levels of FSV, retinol binding protein, total serum lipids, and total bilirubin (TB) were measured 1, 3, and 6 months after HPE. RESULTS: Ninety-two infants with BA were enrolled in this study. Biochemical evidence of FSV insufficiency was common at all time points for vitamin A (29%-36% of patients), vitamin D (21%-37%), vitamin K (10%-22%), and vitamin E (16%-18%). Vitamin levels were inversely correlated with serum TB levels. Biochemical FSV insufficiency was much more common (15%-100% for the different vitamins) in infants whose TB was ≥2 mg/dL. At 3 and 6 months post HPE, only 3 of 24 and 0 of 23 infants, respectively, with TB >2 mg/dL were sufficient in all FSV. CONCLUSIONS: Biochemical FSV insufficiency is commonly observed in infants with BA and persistent cholestasis despite administration of a TPGS containing liquid multiple FSV preparation. Individual vitamin supplementation and careful monitoring are warranted in infants with BA, especially those with TB >2 mg/dL.
