Objective Being

La musculatura del sistema masticatorio y la articulación temporomandibular (ATM) están protegidos por reflejos nerviosos básicos y sistema neuromuscular a través de la coordinación de fuerzas musculares, todo lo que produce sobrecarga muscular repetitiva como los hábitos parafuncionales (HPF) pueden ocasionar trastornos temporomandibulares (TTM)1. Los HPF se caracterizan por movimientos anormales a la función mandibular normal sin objetivo funcional, al estar alterados constituyen una fuente productora de fuerzas traumáticas caracterizadas por dirección anormal, intensidad excesiva y repetición frecuente y duradera (Rolando Castillo Hernández, 2001)4. El objetivo del estudio fue identificar la asociación entre la presencia de hábitos parafuncionales de la cavidad bucal y los TTM en adolescentes de la ciudad de Puebla. Estudio observacional descriptivo. Se incluyeron 258 adolescentes, 132 (51.2%) mujeres y 126 (48.8%) hombres, con una edad promedio de 12.5±.73 y quienes fueron diagnosticados con los CDI/TTM y los HPF fueron auto-reportados por los pacientes. Se encontró una prevalencia de los TTM del 39.9% y una prevalencia de HPF del 86%. Los HPF más frecuentemente reportados fueron la succión labial y la onicofagia. Se encontró una asociación significativa (x2=7.31, p=0.007) entre los hábitos parafuncionales y los TTM en adolescentes. Palabras clave: Trastornos temporomandibulares, hábitos parafuncionales, adolescentes, articulación temporomandibular. Abstract The muscles of the masticatory system and temporomandibular joint (TMJ) are protected by basic nerve reflex and neuromuscular system through the coordination of muscle forces, all that repetitive muscle overload occurs as habit parafunctional (HPF) can cause temporomandibular disorder TMD)1. The characteristics of HPF are abnormal jaw movements without a functional objective. Being the jaw movements altered, they constitute a source of traumatic forces with an abnormal direction, excessive intensity and long-lasting and frequent duration. (Rolando Hernandez Castillo 2001)4. Objective: was to identify the association between the presences of parafunctional habits of the oral cavity and TMD in adolescents in the Puebla city in Mexico. Material and methods: Is a observational study, we included 258 adolescents 132 (51%) females and 126 (48.8%) were men, mean age 12.5±.73 and who were diagnosed with CDI/TTM and HPF were self- reported by patients. Results: The prevalence of TMD was 39.9% and a prevalence of 86% HPF. The most frequently reported HPF were lip sucking and nail biting. We found a significant association (x2= 7.31, p = 0,007) between HPF and TMD in adolescents. Key words: Parafunctional habits of oral cavity, temporomandibular disorders, temporomandibular joint.

Developing Cerebellum

Cytotactin is an extracellular glycoprotein found in a highly specialized distribution during embryonic development. In the brain, it is synthesized by glia, not neurons. It is involved in neuron-glia adhesion in vitro and affects neuronal migration in the developing cerebellum. In an attempt to extend these observations to the peripheral nervous system, we have examined the distribution and localization of cytotactin in different parts of the normal and regenerating neuromuscular system. In the normal neuromuscular system, cytotactin accumulated at critical sites of cell-cell interactions, specifically at the neuromuscular junction and the myotendinous junction, as well at the node of Ranvier (Rieger, F., J. K. Daniloff, M. Pinçon-Raymond, K. L. Crossin, M. Grumet, and G. M. Edelman. 1986. J. Cell Biol. 103:379-391). At the neuromuscular junction, cytotactin was located in terminal nonmyelinating Schwann cells. Cytotactin was also detected near the insertion points of the muscle fibers to tendinous structures in both the proximal and distal endomysial regions of the myotendinous junctions. This was in striking contrast to staining for the neural cell adhesion molecule, N-CAM, which was accumulated near the extreme ends of the muscle fiber. Peripheral nerve damage resulted in modulation of expression of cytotactin in both nerve and muscle, particularly among the interacting tissues during regeneration and reinnervation. In denervated muscle, cytotactin accumulated in interstitial spaces and near the previous synaptic sites. Cytotactin levels were elevated and remained high along the endoneurial tubes and in the perineurium as long as muscle remained denervated. Reinnervation led to a return to normal levels of cytotactin both in inner surfaces of the nerve fascicles and in the perineurium. In dorsal root ganglia, the processes surrounding ganglionic neurons became intensely stained by anticytotactin antibodies after the nerve was cut, and returned to normal by 30 d after injury. These data suggest that local signals between neurons, glia, and supporting cells may regulate cytotactin expression in the neuromuscular system in a fashion coordinate with other cell adhesion molecules. Moreover, innervation may regulate the relative amount and distribution of cytotactin both in muscle and in Schwann cells.
