ABSTRACT
Aesthetic nasal surgery has progressed in the last years, as concerning both surgical techniques and surgical instruments, which allowed the finding of new and more sophisticated surgical solutions. Clinical practice led to observe sometimes functional surgical failures, due rather than an inaccurate surgical technique, to an incomplete diagnostic approach to the patient. It has been observed that modifying the external conformation of nasal pyramidis inner-nose volumes and spaces will be subsequently reduced, giving as a result a condition which is only aesthetically but not functionally valid. 32 subjects, selected for a rhinoplasty and presenting nasal respiratory obstruction and anterior ethmoid abnormalities, confirmed by nasal endoscopy and nasal CT, were evaluated and subdivided into two groups: the first (A) group underwent only to an aesthetic rhinoplasty, the second group (B) was operated of a rhinoplasty combined with functional endoscopic sinus surgery (FESS) in order to correct the above mentioned anatomical abnormalities. The nasal airflow, and though the nasal cavities patency, was evaluated pre- and post-operatively in the two groups of patients, referring to rhinomanometric conductance values. Patients of group A reported decreased post-operative conductance values, patients of group B reported increased post-operative conductance values, showing though the functional involvement of anterior ethmoid in nasal obstruction and the necessity of correcting its anatomical abnormalities, in order to reach not only a new nasal profile, but also a better respiratory performance.

La cirugía estética nasal ha progresado en los últimos años tanto en cuanto a las técnicas quirúrgicas como en cuanto a los instrumentos, que permiten encontrar nuevas y más sofisticadas soluciones quirúrgicas. La práctica clínica nos permite observar a veces fallos quirúrgicos funcionales, debidos más que a una técnica quirúrgica inadecuada, a un abordaje diagnóstico incompleto del paciente. Se ha observado que modificando la forma externa de la pirámide nasal, el volumen y los espacios internos de la nariz se verán consiguientemente reducidos, dando así pues como resultado sólo una condición estética pero no válida funcionalmente. 32 pacientes, seleccionados para rinoplastia y que presentaban obstrucción nasal y anomalias etmoidales anteriores, confirmadas por endoscopia nasal y TC, fueron evaluados y subdivididos en dos grupos: Al primer grupo (A) sólo se le practicó rinoplastia estética y al segundo (B) se le practicó rinoplastia combinada con cirugía endoscópica funcional sinusal (FESS) par corregir las anomalías anatómicas más arriba mencionadas. El flujo nasal y asi pues la permeabilidad de las cavidades nasales, fue evaluado pre y posoperatoriamente en los dos grupos, referidos a los valores rinomanométricos. Los pacientes del grupo A tuvieron valores postoperatorios inferiores y los del grupo B superiores, mostrando así pues la relación funcional del etmoides anterior en la obstrucción nasal y la necesidad de corregir sus anomalías anatómicas, para no sólo conseguir un nuevo perfil nasal, sino también una mejor respiración (AU)

This paper addresses the pedagogical advantages of teaching statistics not as a stand-alone subject in itself, but rather as a topic integrated into teaching hands-on, problem-based computer-assisted data analysis. For over 10 years, such a two-term course has been taught at Drexel University in lieu of the usual statistics courses formerly taken by undergraduate majors in psychology and sociology. One virtue of the courses as currently implemented is that students seem to learn not just how to perform statistical procedures but how to apply them on their own.

The abuse of tranquilizers is recognized as a major health problem. A substantial number of qualitative studies have suggested that the prescribing practices of physicians are at least partly responsible for the problem. Yet there is still a need to test this contention statistically. This paper tests the strength of the relationship over time between physicians' prescriptions of tranquilizers and tranquilizer abuse. Data on physicians' prescriptions are based on projections calculated by the National Disease and Therapeutic Index (NDTI). Data on tranquilizer abuse are based on emergency room episodes reported to the Drug Abuse Warning Network (DAWN). The correlation between physicians' tranquilizer prescriptions and tranquilizer abuse is found to be .46 (significant at the .05 level), after controlling for serial correlations in the data.
