Impact of rheumatoid arthritis in oral surgery and implantology treatment based on literature.

Rheumatoid arthritis (RA) is an autoimmune disease that results in a chronic, systemic inflammatory disorder that principally attacks synovial joints. The pathology of the disease process often leads to the destruction of articular cartilage and the bone. Normal bone remodeling cycle requires the balance between bone resorption and bone deposition which is determined by the activities of two principle cell types, namely, osteoclasts and osteoblasts. Osteoblasts and osteoclasts, coupled together via cytokine mediated cell signaling. The dominance of pro-inflammatory cytokines in bone homeostasis leads to osteolysis. Many articles have been published about the pathobiochemical similarity between rheumatoid arthritis and periodontitis, whereas the role of the disease in bone regeneration and osseointegration is less proven. According to the international literature in rheumatoid arthritis, due to frequent periodontitis, decreased salivary secretion, medication, as well as a decrease in bone regenerative potential, rheumatoid arthritis is considered as relative contraindication in implantology. In daily practice, we face more frequently with rheumatoid arthritis which makes the topic so important in oral surgery and implantology. It can be said that adequate preoperative preparation (healthy periodontal status, antibiotic protection, consultation with the rheumatologist to modify medication) interventions can be done more safely. The risk of failure is higher in patients suffering from rheumatoid arthritis of the underlying disease which fact is important to be communicated before surgical intervention.

[A rare case of fatal outcome due to extensive facial trauma caused by dogbite]. / Kiterjedt arcsérüléssel járó, halálos kimenetelu kutyatámadás ritka esete.

Statistically 10% of head and neek trauma is caused by animal bite, more often inflicted by dogs. More than 50% of victims are infants and small children. Generally, the result of dogbite is superficial trauma but there are cases of deep soft tissue defects with amputation and multiple bone fractures. In case described in this article, an elderly woman suffered a dog attack, wich resulted in extensive face and head injuries. In spite of receiving proper treatment, the patient passed away. It is highly probable that underlying Syncumar therapy caused complications which contributed to the fatal outcome. Because of it's unusual nature we found this case to be of interest for publication.
