RESUMO
Anterior crown fractures are a common form of injury that mainly affect children and adolescents. The position of maxillary incisors and their eruptive pattern carries a significant risk for trauma. In the pre-adhesive era, fractured teeth needed to be restored either with pin-retained inlays or cast restorations that sacrificed healthy tooth structure and were a challenge for clinicians to match with adjacent teeth. The development of adhesive dentistry has allowed dentists to use the patient's own fragment to restore the fractured tooth. Three cases are presented here with complicated crown fracture of maxillary central incisors; the reattachment of the fractured tooth segment in this case has been performed using different combinations of techniques, viz. simple reattachment, circumferential bevel and internal dentinal groove.

Colonic diverticular disease can lead to various complications. We describe a case of an 81-yr-old man who was found to have intrabiliary air on computed tomography of the abdomen. Endoscopic retrograde cholangiopancreatography and subsequent surgical exploration of the abdomen revealed an ascending colonic diverticulum penetrating into the gall bladder. Colocholecystic fistula is an unusual cause of intrabiliary air and, to our knowledge, this has not been reported in the literature.

A 75-year-old woman in accelerated-phase chronic myeloid leukemia with hyperleukocytosis presented with acute respiratory distress syndrome. Despite early and aggressive pulmonary support and cytoreductive chemotherapy, the patient died. Autopsy confirmed the presence of the leukostasis syndrome. The clinical, radiologic, pathophysiologic, and therapeutic aspects of this entity are reviewed.
