Fractures of the mandible and their management are discussed in detail in textbooks and articles dealing with facial trauma. This paper presents the management and treatment of a case of a unilateral comminuted and complicated fracture of the mandible due to dog attack on a geriatric patient. The attack also severed the patient's right arm. Due to the severity of the trauma, an emergency surgery was performed on the mandible and arm. 相似文献

The Phosphatase And Tensin Homolog Deleted On Chromosome 10 (PTEN) regulates the phosphoinositol-3-kinase (PI3K)-AKT signaling pathway. In a series of 34 patients with PTEN mutations, we described gastrointestinal lymphoid hyperplasia, extensive hyperplastic tonsils, thymus hyperplasia, autoimmune lymphocytic thyroiditis, autoimmune hemolytic anemia, and colitis. Functional analysis of the gastrointestinal mucosa-associated lymphoid tissue revealed increased signaling via the PI3K-AKT pathway, including phosphorylation of S6 and increased cell proliferation, but also reduced apoptosis of CD20(+)CD10(+) B cells. Reduced activity of PTEN therefore affects homeostasis of human germinal center B cells by increasing PI3K-AKT signaling via mammalian target of rapamycin as well as antiapoptotic signals. 相似文献

Oropharyngeal mucositis is the acute inflammatory and ulcerative reaction of the oral mucosa following radiation therapy to
the head and neck region. It is such a common problem that nearly all head and neck cancer patients develop some degree of
mucositis. This complication is usually transient in nature but it also represents an important clinical problem as it is
a painful, debilitating, dose-dependent side effect for which there is no widely acceptable prophylaxis or effective treatment.
As several authoritative groups have recently either undertaken systematic reviews or issued guidelines on the management
of mucositis, it is the aim of this review instead, to provide an overview of all the remedies and pharmaceutical agents available,
as well as highlighting to researchers the gaps that need to be filled. 相似文献

This is the first review on orthognathic surgery in Malaysia. The records of a total of 84 patients seen between 1977 and 1999 in the Department of Oral and Maxillofacial Surgery of the Faculty of Dentistry, University of Malaya were analysed. Skeletal III deformity formed 85% of the sample with a female dominance of 2 to 1. The patients' age ranged from 17 to 36 years, with a mean of 25.3 years. The common surgical techniques used were combined bilateral sagittal split and Le Fort I osteotomy. The predominant ethnic group was Chinese (n = 58, 69%); followed by Malay (n = 14, 17%) and Indian (n = 12, 14%). 相似文献

The application of modern research tools has broadened our understanding of the chlamydiae and their role in disease. Chlamydial genome analysis showed the presence of genes for ATP and peptidoglycan synthesis, contradicting the common belief that chlamydiae lack the ability to produce these compounds. Phylogenetic tree analysis suggests that chlamydiae could have evolved from an intracellular existence in amoebae. Newly discovered obligate intracellular organisms with chlamydia-like life-cycles have been classified as chlamydiae by rRNA homology with existing chlamydial species. A proposed new classification adds three new families to the order Chlamydiales as well as creates two genera and nine species within the family Chlamydiaceae. Chlamydiae are incriminated in an increasingly large spectrum of diseases both in humans and in animals. The emergence of multi-drug resistant C. trachomatis strains forewarns therapeutic problems with this organism. While C. pneumoniae remains a significant respiratory pathogen, the role it plays in the pathogenesis of atherosclerosis and ischaemic heart disease awaits definition. 相似文献

This paper reviews the oral and dental lesions that are seen during pregnancy. Trimester approach should be adopted in the management of the pregnant patients. A good dental preventive programme is essential. The significance of prescribing fluoride supplements and the use of dental radiography during pregnancy is also briefly reviewed. 相似文献
