Cervicogenic Headache Differential Diagnosis and Clinical Management: Literature Review

The diagnosis and treatment of patients experiencing head and neck pain is a difficult task for any clinician who pursues this area. The purpose of this paper is to elaborate upon a unilateral headache which is referred to as cervicogenic headache. The literature provides strong evidence demonstrating the relationship of the cervical spine and the possibility of referral pain to the head and facial areas.     

阿司匹林对拔牙创出血影响的研究现状

<正>血栓的形成和栓塞是心脏和大脑缺血性疾病的首要病因。病理研究表明,栓塞的动脉内充满了血小板,其活化和聚集是动脉血栓形成的关键。因此,抑制血小板的活性和聚集功能成为心脑血管疾病药物的作用目标[1]。其中,阿司匹林是该类疾病防治的最常用药物[2]。     

Postextraction complications and the choice of anesthesia

The aim of the investigation is to evaluate the dependence of the most frequent postextraction complications (pain, hemorrhage, hematoma, swelling and dry socket) in relation to the choice of anesthesia. The total of 447 teeth was extracted in 319 male and female persons between 11 and 80 years of age. The most important conclusion of the investigations is that vasoconstrictor in local anesthetic solutions does not influence the incidence of postextraction complications. Clot disturbance, higher incidence of dry socket and unpredicted time of pain appearance were found in the local anesthetic group with lower concentration of vasoconstrictor. Statistically significant difference between local and general anesthesia does not exist in relation to blood clot disturbances, although a great number of clot fails is evident in local anesthetic group. The pain intensity is lower when teeth extraction were performed under general anesthesia.     

即刻种植技术的临床应用

目的:探讨即刻种植技术的临床应用,并对近期效果进行评价。方法:30例患者,62枚种植体,拔除患牙同时植入Camlog系统的牙种植体。前牙区36枚,前磨牙区18枚,磨牙区8枚,其中位于前牙区的6例患者12枚植体进行了即刻负重修复。所有永久修复均在术后3-6个月进行,并定期复诊。观察时间为4-49个月(平均28个月)。结果:有2例位于后牙区的3颗植体在术后2-4周内因松动拔除。其余病例临床效果良好。种植体累积留存率为95.2%。结论:在掌握适应症的情况下,即刻拔牙即刻种植乃至即刻负重,可以取得良好的临床效果。     

Postextraction osteomyelitis in a bone marrow transplant recipient

This report describes a case of mandibular osteomyelitis after a dental extraction in a patient who subsequently underwent bone marrow transplantation (BMT) for lymphoblastic lymphoma. Surgical guidelines consistent with National Cancer Institute recommendations were followed for the extraction, which was performed before initiation of the myelosuppressive conditioning regimen. However, moderate tenderness developed at the extraction site beginning 10 days after marrow infusion. On day 26 the patient became febrile and blood culture-positive for Staphylococcus epidermidis. Radiographs exposed on day 28 demonstrated changes consistent with low-grade osteomyelitis, including diffuse loss of lamina dura and an irregular osseous rarefaction extending 1 cm posterior to the extraction site. Although the indwelling Hickman catheter was the presumed source for bacteremia, clinical and radiographic data led to consideration of mandibular osteomyelitis as an alternative cause. Characteristics of this infection in BMT recipients are reviewed. Recommendations for dental extractions and prophylactic antibiotic regimens for catheterized BMT recipients are also discussed. Although mandibular osteomyelitic lesions are not common in profoundly immunosuppressed BMT recipients, prompt recognition and treatment are essential when the disease occurs.     

Osteoradionecrosis of the Jaws: Clinico-Therapeutic Management: A Literature Review and Update

Osteoradionecrosis is one of the most serious oral complications of head and neck cancer treatment. It is a severe delayed radiation-induced injury, characterized by bone tissue necrosis and failure to heal for at least 3 months. In most cases osteoradionecrosis gradually progresses, becoming more extensive and painful that leads to infection and pathological fracture. The present paper provides a literature review and update on the risk factors underlying osteoradionecrosis, its clinical and diagnostic particulars, prevention and most widely accepted treatment options including the latest treatment modalities. Lastly, a new early management protocol is proposed based on the current clinical criteria relating to osteonecrosis secondary to treatment with bisphosphonates, together with the adoption of new therapies supported by increased levels of evidence.     

Management of Late Post-traumatic Facial Artery Pseudoaneurysmal Cyst: Review of Literature

Pseudoaneurysms of the branches of the external carotid artery as a result of trauma are rare in oral and maxillofacial surgery practice. The most affected branches are the superficial temporal artery, internal maxillary artery and distal part of facial artery, usually where they pass over the bone. Very few cases of facial artery pseudoaneurysms of proximal parts (from external carotid artery up to the lower border of the mandible) are reported in the literature. We present a review of literature for management of late post-traumatic pseudoaneurysmal cyst and a case report involving proximal part of facial artery in the submandibular region following open reduction and rigid fixation of the condylar fracture in a 25-year-old male. To our knowledge this is the fourth reported case of proximal facial artery pseudoaneurysm.
