Five-year results of implants inserted into freeze-dried block allografts.

Purpose: The purpose of this study was to evaluate the outcome after 5 years of allografts as bone growth material and success of implants inserted in fresh-frozen allograft bone.

Materials And Methods: A total of 20 patients were operated and 41 onlay block freeze-dried allografts (calvarial and iliac crest) were inserted for bone augmentation. A total of 64 dental implants were performed in a two-stage procedure.

Management of leishmanial osteolytic lesions in a hypothyroid dog by partial tarsal arthrodesis.

A five-year-old male boxer, previously diagnosed with leishmaniasis and hypothyroidism, had gradually become unable to bear weight on its left hindlimb. Physical examination revealed a left popliteal lymphadenopathy, mild crepitus, and severe swelling of the left tarsal joint, a radiographic examination of which revealed severe bone destruction of the talus and a periosteal reaction of the calcaneus. Laboratory findings and serological tests suggested an active leishmanial infection, and a Leishmania species was identified by direct cytology of a sample from the osteolytic area and by indirect immunohistochemistry of a bone biopsy.

A sucrose-rich diet during pregnancy causes a similar response in Sprague-Dawley and Wistar rats.

Background/aims: In order to determine whether the response to a sucrose-rich diet (SRD) during pregnancy in the rat varies depending on the strain, the responsiveness to a SRD (63 g sucrose/100 g) during pregnancy in Wistar and Sprague-Dawley rats was studied.

Methods: One group of rats of each strain was fed the SRD, whereas another group received the same diet except that sucrose was replaced by an equal amount of cornstarch. Half of the rats were mated, and all animals were studied 20 days later.
