RESUMEN
Salinity reduces feijão-caupi production, and the search for tolerant varieties becomes important within the agricultural context, as, in addition to being used in the field, they can be used in genetic improvement. The objective was to for a identify variety that is tolerant to salinity considering the physiological quality of seeds and seedling growth. A 2 × 4 factorial scheme was used, referring to the varieties Pingo-de-ouro and Coruja, and four electrical conductivities of water (0; 3.3; 6.6 and 9.9 dS m-1). The physiological quality of seeds and the growth of seedlings were analyzed, in addition to the cumulative germination. The Pingo-de-ouro variety showed no germination, length of the shoot and root, dry mass of the shoot and root compromised up to electrical conductivity of 6 dS m-1 in relation to 0.0 dS m-1. On the other hand, the Coruja variety showed reduced germination, increased shoot and root length. The creole variety Pingo-de-ouro proved to be tolerant to salinity.

OBJECTIVE: The present article aims at describing a rare case of an RP patient who evolved with heart block and was successfully treated with corticoid pulse therapy, without the need for pacemaker insertion. PATIENTS AND METHODS: A systematic research on relapsing polychondritis (RP) and heart block (HB) published in PubMed/MEDLINE, Web of Sciences, LILACS, and Scielo from 1966 to August 2020 was performed. RESULTS: It was found 10 studies on RP associated with HB, and we added a case. Most were male (7/10) with ages 30 to 66 years old. RP disease duration was 1 week-6 years. In most cases (7/10), the RP was active when the HB occurred. A complete HB was observed in 4/7, followed by type II degree block in 3/7, and one patient had a sinus node dysfunction. Most patients received glucocorticoids. A pacemaker was inserted in 4/9 cases. Good outcome was observed in 3/9 patients and mortality in 2/10. CONCLUSIONS: We report the first case of an RP patient who had a heart block and was successfully treated with methylprednisolone pulse therapy. The authors suggest that in these RP cases, an attempt with a glucocorticoid pulse therapy may be offered to treat the heart block and prevent the insertion of a pacemaker.
