Rheumatic manifestations of scurvy. A report of two cases.

Bleeding into the muscles and joints can be the presenting manifestation of scurvy, as illustrated by two case-reports. One patient presented with hemarthrosis of the tibiotalar joint due to an insufficiency fracture and was suspected to have scurvy based on the presence of purpura and hypertrophy of the gums with loss of teeth. In the other patient, multiple hematomas in the lower limbs were found at presentation and the presence of coiled hairs suggested the diagnosis. Both patients had completely eliminated fruit and vegetables from their diet. Low levels of ascorbic acid were found in serum and urine. A full recovery was achieved in both cases under ascorbic acid supplementation.

[Influence of seasons on risk of flare-up of systemic lupus: retrospective study of 66 patients]. / Influence de la saison sur le risque de poussée systémique du lupus: étude rétrospective de 66 patients.

PURPOSE: To establish the possible connection between visceral, arthro-cutaneous and biological spreading of systemic lupus (SL) and hours of sunlight. MATERIAL AND METHODS: Retrospective study of 66 SL patients, consisting of 52 visceral and 14 arthro-cutaneous cases taking into account the chronological pattern of each new aggravation, based on 480 clinical records. RESULTS: Increased frequency in visceral aggravation was observed in the post-summer period (August-January) (n = 57), as compared with the pre-summer period (February-July) (n = 25) (RR = 1.75, P = 0.006). This post-summer visceral aggravation was correlated with cutaneous affection (RR = 4.18) and absence of previous corticotherapy (RR = 3.97). Visceral and arthro-cutaneous aggravations taken together revealed a more disturbed immune balance pattern in the post-summer period (anti-dsDNA: 30 versus 25.1 IU/L [P = 0.07]; C3: 0.83 vs 0.921 IU/L [P = 0.05]; C4: 0.146 vs 0.183 [P = 0.05]), providing evidence of greater severity. Moderate thrombopenia (50-120 10(9)/L) accompanying visceral SL with antiphospholipids (n = 33) was more frequent during the post-summer period, even in the absence of aggravation (P = 0.03). The quarterly distribution of visceral aggravations was correlated with average hours of sunlight in the preceding quarter (P = 0.01). CONCLUSION: There is a post-summer increase in the frequency and severity of visceral SL spreading correlated to cutaneous exacerbation and sunlight.
