Eagle's syndrome: lesser cornu amputation: an alternative surgical solution?

A case is reported of a 42-year-old female patient, who presented with clinical symptoms of Eagle's syndrome, radiographic evidence of marginally elongated styloid processes as well as markedly elongated lesser cornua of the hyoid. The symptoms were successfully treated by amputating the lesser cornua of the hyoid. The patient has now been asymptomatic for more than 6 years.     

Commentary: Periodontitis and Rheumatoid Arthritis: What Do We Know?

Background: Currently, in the field of rheumatology, there is much attention given towards the possible causality between periodontitis and rheumatoid arthritis (RA), specifically regarding the role of Porphyromonas gingivalis (Pg). This bacterium is unique, having a citrullinating enzyme. Antibodies against citrullinated proteins are rather specific for RA. Methods: Because causality is ultimately tested in longitudinal cohort studies which currently do not exist for periodontitis and RA, this commentary applied Bradford Hill criteria on the existing literature to assess causality as the most likely interpretation of this association. Conclusions: From an epidemiologic point of view, patients with RA have a higher incidence of periodontal disease than individuals without RA. In addition, there is a dose‐response pattern in the association between the severity of periodontitis and RA disease activity. There are indications that periodontitis precedes RA, but there is no evidence yet available to show that Pg plays a direct role in this temporal relationship. The role of the unique characteristic of citrullination by Pg remains unexplained. However, in animal models, citrullination by Pg plays a distinct role in the development and aggravation of experimental arthritis. Although the role of Pg in RA remains speculative, a causative role for periodontitis as a chronic inflammatory disease caused by infectious agents in RA seems biologically plausible.     

Erratum to: ZURÜCKGEZOGEN: Belastungsmessungen nach der Miniplattenosteosynthese von Unterkieferwinkelfrakturen

Aims

The aim of this study was to evaluate the load resistance of mandibular angle fractures treated with a miniplate osteosynthesis according to Champy.

Material and methods

We evaluated 22 completely dentate patients with fractures of the angle in addition to 15 controls. An electric test procedure for the determination of the load resistance between the incisors, canines and molars was carried out 1–6 weeks after treatment.

Results

At 1 week postoperatively 90 N was registered between the molars while after 6 weeks this was148 N. This revealed only 31% and 58% of the maximal vertical load found in the controls, respectively.

Conclusion

The minipate osteosynthesis according to Champy offers a secure method in the treatment of mandibular angle fractures with sufficient stability. Maximum voluntary bite forces were not registered during the time of healing.      

硬皮病:口腔的表现

硬皮病为一种系统性胶原病。除皮肤外,还可累及胃肠道、心、肺、肾等器官;其特点为胶原增殖,血管壁有炎性改变及球蛋白沉积。硬皮病也可侵犯口腔及其周围组织,常使面部皮肤及舌体变硬,也可使软腭、喉、小唾液腺受累。X线片可见颌骨有改变与牙周膜增宽,文献报导牙周膜增宽可见于10—37％病人,但并不是所有牙增宽,其增宽程度并不一致,后牙大于前牙。颌骨之吸收可发生于喙突、升枝后缘及髁突。作者于17年内调查了21个女病人,年龄27—63岁,13个在50岁以上,病程为3—49年。其中17例(80％)有张口受限(张口度<4cm),20例诊断有牙周病,但只有13个牙

Commentary: Periodontal Treatment and Inflammation in Diabetes: Association or Causation?

The causal effect of periodontal treatment on systemic outcomes is unclear because even randomized controlled trials (RCTs) have conflicting results. Two models are proposed to explain the apparently conflicting findings from RCTs evaluating the effect of periodontal treatment on inflammation and systemic outcomes among individuals with type 2 diabetes.     

Woman and career: an unhappy marriage? A study model: dentistry

Women's participation in the professions is steadily increasing. This study is a quantitative assessment of male and female career patterns in dentistry and of the role of marriage in any gender gap. A 1997 survey explored the professional activity of Flemish dentists. There is no educational disparity between dentists, female dentists enter the profession on an equal footing with their male colleagues. Therefore any other career influencing factors reveal themselves relatively clearly. Dependent variable was income; independent variables were gender and marriage. Female dentists scored lower than male dentists in each career phase; marriage made no significant difference. However, marriage turned out to be an important positive factor in the career of male dentists. Women dentists marry significantly later and less than their male colleagues. Further research, also of a qualitative nature, is necessary to evaluate the professional and social impact of this substantial gender difference.

Cleft palate and bilateral congenital cataract: a familial observation: a new syndrome?

We report a family with a rare association of congenital bilateral cataract and cleft palate that has not to our knowledge been previously reported. The lineage has unveiled abnormalities over four generations affecting 21 people with congenital bilateral cataract, with or without cleft palate. The transmission seems autosomal dominant. Four brothers and sisters presented with this defect, and a fifth sister is healthy. The mother has facial dimorphism, congenital bilateral cataract, submucous cleft palate, clinodactyly, and scoliosis. The propositus' karyotype was normal. Array comparative genomic hybridisation (CGH) analysis showed an interstitial amplification in Xp21.1, found in the mother, in all the affected siblings but one, and in the healthy girl. Thisl association is not rare and has been reported in over 50 syndromes but rarely in familial observations. Based on the genetic-clinical discordance we wonder about the deleterious impact of the Xp21.1 amplification that might be a copy number polymorphism.
