RESUMEN
OBJECTIVE: Childhood overweight and obesity have been identified as a significant global health problem, and have multiple health and socio-emotional sequelae. The family context and parenting behaviours in particular play an important role in childhood overweight and obesity; however, limited research has explored the relationship between parenting and child obesity. The aim of this research was to refine the content of a tool designed to assess child lifestyle behaviour problems and parents' confidence in managing these behaviours. DESIGN: Content revisions of the Lifestyle Behaviour Checklist (LBC) were undertaken, and the psychometric properties were examined. SUBJECTS: One hundred and fifty-six parents of an overweight or obese child completed the LBC, as well as questionnaires regarding child behaviour in general and parenting practices. RESULTS: The results of this study support the validity of the revised LBC as a measure of parental concerns about weight-related problem behaviour, and provide evidence for a four-factor structure and strong internal consistency.

The usefulness of the rapid exchange grip test and a modification of this test, the rapid simultaneous grip test, in detecting submaximal grip efforts was evaluated. Uninjured subjects giving maximal or submaximal grip efforts were tested at grip rates of 80 and 100 repetitions per minute. Rapid exchange grip at 80 repetitions per minute yielded a sensitivity of 86% and a specificity of 97%. Rapid simultaneous grip at 80 repetitions per minute yielded a sensitivity of 81% and a specificity of 93%. Poorer sensitivities and specificities resulted when a clinical population of patients was tested. Patients who were not giving maximal efforts tended not to comply with the test protocol. The rapid exchange and rapid simultaneous grip tests do assist in detecting submaximal grip efforts; limits to these tests are emphasized.

The case of a symptomatic persistent orbital--antral fistula after silicone orbital floor reconstruction is presented. Intermittent diplopia with Valsalva maneuvers was the patient's chief complaint. Periorbital cellulitis was a suspected complication of the fistula. This case emphasizes the importance of an often overlooked goal of orbital floor reconstruction, that is, isolation of the orbital cavity from the maxillary sinus. Greater care in positioning alloplastic implants may improve their function. Autogenous materials may be superior in orbital floor reconstruction.

We report a case of primary malignant melanoma arising in the mucosa of the nose and paranasal sinuses. Clinical presentation and course of this rare type of melanoma are described, and the surgical management is discussed.
