Crouzon syndrome in a fraternal twin: A case report and review of the literature.

Background: Crouzon syndrome (CS; OMIM 123500) is an autosomal dominant inherited craniofacial disorder caused by mutations in the () gene. CS is characterized by craniofacial dysostosis, exophthalmos, and facial anomalies with hypoplastic maxilla and relative mandibular prognathism.

Case Summary: Our report involves a 6-year-old fraternal twin boy with many caries in the oral cavity who presented with characteristic features of CS based on clinical and radiographic examinations along with Sanger sequencing.

[Expression of fibroblast growth factor receptor like 1 protein in oral squamous cell carcinoma and its influence on tumor cell proliferation and migration].

Objective: This study aims to investigate the expression of fibroblast growth factor receptor like 1 (FGFRL1) in oral squamous cell carcinoma (OSCC) and reveals its association with tumor cell proliferation and migration.

Methods: Western blot was performed to detect the expression of FGFRL1 protein in OSCC tissues, adjacent normal tissues, OSCC cell lines and normal epithelial cells. After knocking down of FGFRL1 in HN4 cells, CCK-8 and Ki67 assays were performed to detect cell proliferation, wounding healing assay and transwell were performed to detect cell-migration.

Three years of follow-up of otodental syndrome in 3-year-old Chinese boy: a rare case report.

Background: Otodental syndrome is an exceptionally rare autosomal dominant condition characterized by a delayed eruption of posterior teeth, globodontia, lisping, and sensorineural hearing loss. In this case report, we reported a 3-year-old Chinese boy with the otodental syndrome.

Case Presentation: A 3-year-old Chinese boy was referred to our hospital with complaint of no eruption of primary canines and molars.

A case report of hemolytic streptococcal gangrene in the danger triangle of the face with thrombocytopenia and hepatitis.

Background: Hemolytic streptococcus gangrene is a life threatening invasive bacterial infection. Hemolytic streptococcus gangrene in the danger triangle of the face is too lethal to operate. A case of the confirmed hemolytic streptococcus gangrene in the danger triangle of the face caused by Group A beta-hemolytic streptococcus (GAS) in 20-months old boy is presented to draw attention of clinicians to this uncommon but frequently fatal infection.

[Role of immunologic abnormality in recurrent parotitis in children].

Objective: To investigate the relationship between immune function and the recurrent parotitis (RP) for children.

Methods: The children diagnosed as RP were divided into two groups: aged under 6y and over 6y and the immune function were measured and compared with that of normal children.

Results: For RP children the ratio of CD4+ T cell in over 6y group was significantly lower than that in under 6y group (P<0.

[The study of emergency facial trauma in children and parents' cognition on it].

Objective: To analyze the characteristics of emergency facial trauma in children and mother's cognition on it.

Methods: Descriptive analysis was undertaken for 216 children with maxillofacial trauma. The analysis included age distributions of the children, reasons and places for the trauma, and positions and severity degrees of the trauma.

[Children's temperament characteristics and dental fear].

Objective: To evaluate the relationship between children's temperament and dental fear.

Methods: 254 children(aged 4-6 years) during first dental treatment took part in the investigation. Their parents answered the Chinese preschool children's temperament scales (CPTS).

Pressure from the lips and the tongue in children with class III malocclusion.

Objective: To discuss possible relationships between class III malocclusion and perioral forces by measuring the pressure from the lips and the tongue of children with class III malocclusion.

Methods: Thirty-one children with class III malocclusion were investigated and their perioral forces were measured at rest and during swallowing under natural head position by a custom-made miniperioral force computer measuring system.

Results: The resting pressures exerted on the labial side and palatine side of the upper left incisor, as well as the labial side and lingual side of the lower left incisor, were 0 g/cm(2), 0 g/cm(2), 0.

[The characteristics of uncooperative children's temperament during dental treatment].

Purpose: To compare the temperament of uncooperative and cooperative children during dental treatment, and find out the characteristics of the uncooperative children's temperament.

Methods: Fifty-two cooperative children (aged from 3 to 7 years) and thirty-five uncooperative children (aged from 3 to 7 years) during dental treatment were included in the investigation. Their parents were asked to answer the Chinese Preschool Children's Temperament Scale (CPTS).

Muscular forces exerted on the normal deciduous dentition.

This study evaluated the distributing characteristic of the forces exerting on the normal deciduous dentition and the relationship between the muscular forces, sex, and oral function. The pressure measurements were made with a computer-aided perioral force-measuring system designed by the authors. The forces were measured when the subject's head position was in a state of natural head position and oral function was at rest or with swallowing.

[Study of muscle pressure exerted on deciduous normal occlusion].

Objective: To measure the muscle pressure exerted on the deciduous normal occlusion and to explore the relationship between the denture,occlusion, skeleton and muscle pressure.

Methods: Thirty volunteers of deciduous normal occlusion were included in the study. The muscle pressure of natural head posture (NHP) was measured at rest and during swallowing by a PC real-time measuring system and the data were analyzed by statistical software SAS.
