Systemic antibiotics and debridement of peri-implant mucositis. A randomized clinical trial

This RCT compared non-surgical treatment of peri-implant mucositis with or without systemic antibiotics.

Unusual systemic signs in a dog with sterile neutrophilic-macrophagic lymphadenitis and nodular panniculitis

A 7 mo old female English springer spaniel was presented with diarrhea, vomiting, apathy, and hyperthermia. Further examinations revealed generalized lymphadenomegaly consistent with sterile neutrophilic-macrophagic lymphadenitis and pulmonary involvement. Subcutaneous nodules developed one day after presentation. Histology was consistent with sterile idiopathic nodular panniculitis and vasculitis. No infectious organism was isolated. The dog responded to prednisolone, but relapsed during medication tapering. Cyclosporine had to be added to control the disease. No further relapse had occurred 98 wk after the first presentation. This is an unusual presentation of a systemic sterile neutrophilic-macrophagic lymphadenitis with nodular panniculitis and vasculitis associated with gastrointestinal and pulmonary signs.

Occurrence of systemic hypertension in dogs with acute kidney injury and treatment with amlodipine besylate

OBJECTIVES: To describe the occurrence of systemic hypertension in dogs with acute kidney injury and the efficacy of amlodipine besylate for its treatment. METHODS: This retrospective study included 52 dogs with acute kidney injury (2007 to 2008) grouped based on the use of amlodipine in their treatment. Systemic blood pressure was measured with an oscillometric device at admission, before, during, and after amlodipine therapy. RESULTS: Occurrence of systolic systemic hypertension (>/=160 mmHg) and severe systolic systemic hypertension (>/=180 mmHg) was 37% and 15% at admission and increased with hospitalisation to 81% and 62%, respectively. Twenty-two dogs were treated with amlodipine, at a median daily dosage of 0.38 mg/kg (interquartile range 0.28 to 0.49) divided in one to two applications per day. Amlodipine therapy was associated with a decrease in systolic systemic blood pressure of 24 mmHg (12 to 34) and a correction of severe systemic hypertension in 10 of 11 dogs within 24 hours. Overall, 73% of the dogs survived with a significantly lower proportion of survivors in treated compared to non-treated dogs (59% versus 83%, respectively, P=0.05). CLINICAL SIGNIFICANCE: Results of this study reveal that systemic hypertension is common in canine acute kidney injury and that treatment with amlodipine is beneficial in reducing systemic hypertension. The potential effect of amlodipine on global outcome requires prospective assessment.
