Arthrogryposis multiplex congenita

From 1975 to 2004 a total of 38 children handicapped by congenital multiple arthrogryposis were cared for. The congenital joint contractures demand a major effort in terms of surgical reconstruction. In the case of distal arthrogryposis the chances that patients will be able to walk without help are good, while those with amyoplasia are likely to be dependent on mobility aids throughout their lives. The ultimate goal of treatment for patients is to develop into self-confident adults who can cope with life despite their handicaps. The hip in arthrogryposis shows variable forms of pathology, ranging from the almost normal hip to hip contractures with dislocation. Its treatment has some limited advantages, but hardly improves mobility. The knee contractures are actively treated to allow patients to sit, stand and walk better. The club foot and the rocker-bottom foot need sophisticated conservative and operative treatments. If conservative manipulation of bilateral extension contractures of the elbow fails operative treatment is carried out on the dominant side. For shoulder, hand and finger contractures conservative manipulation brings about little improvement, and surgical approaches help hardly at all.     

Déficit émotionnel et intelligence machiavélique : étude des interrelations entre l'échelle d'alexithymie de Toronto (TAS-20) et l'inventaire mach-iv dans une population de 201 étudiants

The aim of the study was to explore the relationship between alexithymia and machiavellianism in a group of 201 university students. The subjects filled out the TAS-20 and the MACH-IV forms. The results showed firstly, a significant correlation between the two total scores (r = 0.35, P < 0.05), and secondly between the identification of feelings subscale of the TAS-20 and the opinions about human nature subscale of the Mach-IV (r = 0.44, P < 0.05). The results were discussed in light of the different factors (depression, dependency, psychoticism…) that could explain the relationship between the two concepts.     

Cryosurgical treatment of gingival melanin pigmentation with tetrafluoroethane.

OBJECTIVE: To introduce 1,1,1,2 tetrafluoroethane (TFE), as a new material for cryosurgery of gingival melanin pigmentation (GMP). STUDY DESIGN: Twenty-one patients with GMP were treated using a TFE-cooled cotton swab. Standard digital images of pigmented areas were measured preoperatively and postoperatively with image-analyzing software. The Mann-Whitney U test was used for statistical analysis. RESULTS: Keratinization was completed 3 to 4 weeks after application, without any trace of pigmentation. Statistical analysis revealed a significant difference between preoperative and postoperative measurements of pigmented areas (P < .05). During the follow-up period, no side effects were observed and improved esthetics were maintained up to month 30. CONCLUSIONS: The clinical outcomes of cryosurgery with TFE for treatment of GMP are very satisfactory. The use of TFE for cryosurgical treatment of GMP is practical and inexpensive. Moreover, unlike other cryosurgery methods no special equipment is required, and it is safe to store in the dental clinic.
