ABSTRACT
Acute rheumatic fever (ARF) carditis is treated with steroids, which can cause changes in the cellular immune response, especially decreased CD3 (+) T cells. Nosocomial infections due to steroid use for treatment of ARF carditis or secondary to the changes in the cellular immune response have not been reported in the literature. Sphingomonas paucimobilis is a Gram‑negative bacillus causing community‑ and hospital‑acquired infections. It has been reported as causing bacteraemia/sepsis, pneumonia or peritonitis in patients with malignancies, immunosuppression or diabetes. We present a case with S. paucimobilis bacteraemia/sepsis and shock after administration of steroids for treatment of ARF carditis. We suggest early identification of the causative agent and appropriate adjustments of the treatment plan to avoid shock and possible mortality. This is the first reported case of S. paucimobilis bacteraemia/sepsis in the setting of steroid use for ARF carditis.
ABSTRACT
Talon cusp is a developmental dental anomaly thought to arise as a result of evagination on the surface of a tooth crown before calcification has occurred. The etiology remains unknown. The incidence is 0.04-10%. Any tooth may have a talon cusp but most of the cases involve maxillary lateral incisors, with some instances of bilateral involvement. The anomaly has been reported to be rare in the mandible. This article reports four cases of talon cusp. The first and the second cases describe bilateral involvement of talon cusp on palatal surfaces of maxillary primary centrals; in the third case talon tubercle occurs on palatal surfaces of both maxillary permanent lateral incisors and the maxillary left central incisor and in the last case a talon cusp in the lingual surface of mandibular permanent lateral incisor.
