Odontome composé: à propos d'un cas clinique

Les odontomes sont des tumeurs bénignes des maxillaires composées de dérivés de l'épithélium odontogène et de l'ectomésenchyme. Ils sont divisés en deux groupes: odontome composé et odontome complexe. L'odontome composé est constitué de nombreuses dents rudimentaires, de très petite taille, groupées dans un sac dont la paroi conjonctive est identique à celle du follicule dentaire normal. Il s'agit d'une jeune patiente qui s'est présentée à la consultation pour une tuméfaction maxillaire antérieure évoluant depuis 4 ans. La patiente a rapporté qu'elle a subi un traumatisme à l'enfance. L'évolution de la tuméfaction était asymptomatique. L'examen exobuccal était sans spécificité. L'examen endobuccal a montré la présence au niveau de la muqueuse vestibulaire du maxillaire antérieur, d'une tuméfaction dure à la palpation et indolore. La muqueuse de recouvrement était d'aspect normal. La TDM a montré des images radiopaques entourées d'un halo radioclaire au niveau du secteur maxillaire antérieur droit autour de la racine de la 11, avec une rupture de la corticale externe et sans envahissement des fosses nasales. Les données cliniques et radiologiques ont orienté vers un odontome composé. Une exérèse chirurgicale des odontomes a été réalisée. L'odontome fait partie des tumeurs odontogéniques benignes épithélio-mésenchymateuses mixtes. L'étiologie de l'odontome est inconnue. Il peut apparaître suite à un ancien traumatisme. Les odontomes composés sont asymptomatiques et découverts au cours d'un examen radiographique de routine. Le traitement consiste à l'extraction chirurgicale de l'odontome seule ou suivi d'un traitement orthodontique en cas d'inclusion d'une dent

Odontomas are benign jaw tumors composed of derivatives of odontogenic epithelium and ectomesenchyme. They are divided into two groups: compound odontoma and complex odontoma. A compound odontoma is made up of many rudimentary teeth, very small, grouped in a sac whose connective wall is identical to that of the normal tooth follicle. A young patient presented for the consultation for an anterior maxillary swelling that has progressed for 4 years. The patient reported that she suffered trauma as a child. The progression of the swelling was asymptomatic. The extra oral examination was unspecific. Intraoral examination showed the presence in the vestibular mucosa of the anterior maxilla, a swelling that was hard on palpation and painless. The covering mucosa was normal in appearance. CT showed radiopaque images surrounded by a radiolucent halo in the right anterior maxillary sector around the root of 11, with a rupture of the external cortex and without invasion of the nasal cavity. Clinical and radiological data have pointed to a compound odontoma. Surgical removal of the odontomas was performed. Odontoma is one of the benign mixed epithelial-mesenchymal odontogenic tumors. The etiology of odontoma is unknown. It can appear following an old trauma. Compound odontomas are asymptomatic and discovered during routine radiographic examination. Treatment consists of surgical extraction of the odontoma alone or followed by orthodontic treatment in the event of inclusion of a tooth.

Outcome and influential factors of speech therapy delivered to cleft patients with post-operative velopharyngeal competence / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To analyze the training technique, intervention timing, and other related factors involved in the speech therapy delivered to cleft patients with velopharyngeal competence after surgery.</p><p><b>METHODS</b>A retrospective study was conducted on 32 patients who received phonology-articulation speech therapies during 2012 to 2013 in Dept. of Cleft Lip and Palate, West China Hospital of Stomatology, Sichuan University. All patients achieved normal speech one year after therapy. Information collected included the types and number of consonant articulation error, the overall period of training, the interval between surgery and speech training, and the age during speech training. Statistical analyses were performed in SPSS 16.0.</p><p><b>RESULTS</b>Ten patients received less than five sessions of training, seventeen received six to ten sessions, and five received eleven to twenty sessions. The number of sessions was positively correlated with the number of errors (r(s)=0.394, P=0.026). On the average, each additional error cost another 0.570 session for correction (confidence interval: 0.137-1.004). Moreover, the number of sessions was negatively correlated with age (P=0.055). Patients between 5 to 10 years old took significantly lesser sessions than those above 10 years. No correlation was found between the number of sessions and the interval between surgeries and trainings.</p><p><b>CONCLUSIONS</b>Appropriate speech therapy efficiently rehabilitate the speech condition of cleft patients with velopharyngeal sufficiency after surgery. The number of errors is directly proportional to the number of sessions needed. Patients above 10 years require more sessions than those less than 10 years.</p>

To Write The Medical Research Contract From The Angle of Funding Management / 中华医学科研管理杂志

Medical research contract is an important part of business between medical research organizations.It is the official document identifying the right and obligations of respective medical research organizations during research activities.It is the legal basis,and is also on the basis of research expenditure.Therefore,it is very important to improve ability of the contract writing in research management.Composing a sound medical research contract has significant importance in research activities.This paper explored the remarkable issues when composing a medical research contract from the respective of management of funding,including how to make the contract more fair,rational,rigorous and legal.

Application research of remifentanil in patients with mechanical ventilation in ICU / 重庆医学

Objective To observe the efficacy and safety of remifentanil in patients with mechanical ventilation in Intensive Care Unit (ICU) .Methods Totally 90 cases were enrolled ,patients with mechanical ventilation were randomly divided into two groups (remifentanil vs .fentanyl) ,45 cases in each group .We used facial expression score (FPS) to monitoring pain ,richmond se‐dation agitation score (RASS) was the sedation tool for measuring quality and depth of sedation .Propofol wase used for sedation therapy .We recorded the data including FPS and RASS and vital signs during the treatment .The primary outcome was the time to reach the goal of analgesia sedation ,cases of using propofol and doses of propofol .The secondory outcome was mechanical ventila‐tion time ,ICU length of stay and adverse events .Results Fentanyl and remifentanil all could achieve the desired analgesic effect . Compared with fentanyl group ,FPS scores showed significantly decreased after 5 min application of remifentanil (P0 .05) .The mechanical ventilation time ,ICU length of stay in the patients with remifentanil were significantly shorter(P<0 .05) ,and adverse events occur less(all P<0 .05) .Conclusion Remifentanil analgesia in patients mechanical ventilated patients is fast onset of action ,analgesic effect significantly ,with less sedative drug dosage .It also can shorten mechanical ventila‐tion time ,ICU length of stay and has no obvious side effects .
