A review of facial injuries due to dog bites
Bite injuries to the head and neck region can result in facial disfigurement with distressing physical and psychological consequences. This article reviewed the causes and management of facial bite wounds due to dog bites. A PUBMED search of the National Library of Medicine from 1995 to December 2005 was conducted. Keywords used in the search were ?facial wound?, ?bite wound?, ?dog bite?. The results showed that the risk factors for dog attacks include: school-aged children, male, households with dogs, male dogs and certain breeds (german shepherds, bull terriers, blue/red heelers, dobermans and rottwellers). Early management of such complex injuries usually guarantees satisfactory outcome.…
Cerebrospinal fluid rhinorrhoea: diagnosis and management
A cerebrospinal fluid (CSF) rhinorrhoea occurs when there is a fistula between the dura and the skull base and discharge of CSF from the nose. CSF rhinorrhea or liquorrhoea commonly occurs following head trauma (fronto-basal skull fractures), as a result of intracranial surgery, or destruction lesions. A spinal fluid leak from the intracranial space to the nasal respiratory tract is potentially very serious because of the risk of an ascending infection which could produce fulminant meningitis. This article reviewed the causes, diagnosis and treatment of CSF leakage. A PUBMED search of the National Library of Medicine was conducted. CSF leak most commonly occurs following trauma and the majo…
Fragmented adipose tissue graft for bone healing: histological and histometric study in rabbits' calvaria
Objective The adipose tissue represents an important reservoir of stem cells. There are few studies in the literature with which to histologically evaluate whether or not the adipose tissue graft is really a safe option to achieve bone repair. This study histologically analyzed the effect of fragmented autogenous adipose tissue grafts on bone healing in surgically created, critical-size defects (CSD) in a rabbit’s calvaria. Study design Forty-two New Zealand rabbits were used in this study. CSD that were 15 mm in diameter were created in the calvarium of each animal. The defects were randomly divided into two groups: in Group C (control), the defect was filled only by a blood clot and, in G…
Biomechanical aspects of external root resorption in orthodontic therapy
External apical root resorption is a common phenomenon associated with orthodontic treatment. The factors relevant to root resorption can be divided into biological and mechanical factors. Some mechanical and biological factors might be associated with an increased or decreased risk of root resorption during orthodontic treatment. For mechanical factors, the extensive tooth movement, root torque and intrusive forces, movement type, orthodontic force magnitude, duration and type of force are involved. For biological factors, a genetic susceptibility, systemic disease, gender and medication intake have been demonstrated influence root resorption. Orthodontic therapy of patients with increased…
