The role of nigral and thalamic output pathways in the expression of oral stereotypies induced by amphetamine injections into the striatum

Microinjections of amphetamine into the ventrolateral striatum (VLS) elicit a striking behavioral syndrome characterized by compulsive oral and forelimb motor stereotypies. The neural pathways that mediate these behavioral responses downstream from the striatum have not yet been identified. In a series of experiments, we investigated the involvement of the substantia nigra pars reticulata (SNr) and the ventromedial nucleus of the thalamus (VMT) in the mediation of this behavioral syndrome. We demonstrated that lidocaine-induced reversible inactivation of the SNr reduced amphetamine-induced stereotyped biting and gnawing behaviors, suggesting that the nigral output pathway plays a significant role in the expression of these behavioral responses. In turn, injections of lidocaine into the VMT only transiently reduced amphetamine-stimulated biting and increased stereotyped gnawing and paw nibbling, suggesting that the expression of oral stereotypies induced by amphetamine injections into the VLS is not dependent on thalamocortical feedback.

Myocutaneous v/s micro vascular free flaps in oral cavity reconstruction - a comparative study

Micro vascular free tissue transfer scores over the traditional myocutaneous flaps by providing better cosmesis and function. However, the increased operating tine and costs and the necessity for two operating teams sometimes, negate these advantages and even where this facility is freely available, myoentancous flaps continue to be widely used. To determine the ideal choice of reconstruction in patients after oral resection, we compared our experience with these two methods of reconstruction. Since 1997, when we first started micro vascular reconstruction, 17 patients have undergone this procedure for oral reconstruction. During this same period, 40 patients had pectoralis major myocutaneous flap reconstruction of the oral cavity. These two groups are compared with regard to cosmetic and functional results (as measured by patient’s level of satisfaction) operating time, duration of hospitalization, cost and complications. Results: Eightv seven percent of the patients in the micro vascular group and 75% in the myocutaneous group were satisfied with the cosmetic and functional results. In the microvascular group, average operating time was increased by 4 hours; hospitalization by 3 days and average cost of treatment was doubled. Flap failures and re-explorations were significantly higher in the micro vascular group. Based on these results, we would like to suggest the ideal method of reconstruction of the oral cavity in specific subgroups of patients in a corporate hospital setting.

How well do parents know their children? implications for proxy reporting of child health-related quality of life

OBJECTIVES: This study examined parental knowledge of their children's oral-health-related quality of life (OHRQoL) (Objective 1), and the effects of different analytical techniques to manage 'Don't know' (DK) responses on the validity and reliability of the questionnaire (Objective 2) and the level of agreement between parental and child reports (Objective 3). METHODS: The parental (PPQ) and child (CPQ11-14) components of the Child Oral Health Quality of Life Questionnaire were used. Objectives 1 and 2 were addressed in the study that involved 221 parents and Objective 3 in the study that involved 63 pairs of parents and children. Four methods for treating DK responses in the PPQ were tested: listwise deletion, item mean imputation, imputation of the value zero and adjustment of scores to account for items with DK responses. RESULTS: Respectively, 26 and 11% of the parents gave > or = 3 and 6 > or = DK responses to 33 items comprising the PPQ. DK responses were associated with child's age and clinical condition, and parental gender. The methods of managing DK responses did not have differing effects on the measurement properties of the PPQ and the level of agreement between parents and children. CONCLUSION: Some parents have limited knowledge concerning their children's OHRQoL. However, given that parental and child reports are measuring different realities, information provided by parents is useful even if it is incomplete.
