Dynamic near-real-time magnetic resonance imaging for analyzing the velopharyngeal closure in comparison with videofluoroscopy

PURPOSE: To demonstrate the feasibility of dynamic magnetic resonance imaging (MRI) with near-real-time temporal resolution ("real-time MRI") for analyzing the velopharyngeal closure in comparison with multiview videofluoroscopy. MATERIALS AND METHODS: Seven patients (three females and four males, 5-21 years old, mean age=11.3 years) with suspected velopharyngeal insufficiency, and one healthy volunteer were examined with videofluoroscopy and real-time MRI using a turbo-spin-echo (TSE) sequence (TR=170 msec, TE=21 msec, slice thickness=6 mm, six images per second). Imaging was done during phonation in all three image planes. The results were analyzed by two radiologists in comparison with videofluoroscopy as the standard of reference for overall image quality and the pattern of velopharyngeal closure. RESULTS: Real-time MRI correctly depicted the pattern of velopharyngeal closure in correspondence to videofluoroscopy in all cases. Concerning the movement of the pharyngeal walls, real-time MRI falsely depicted a general movement of the dorsal pharyngeal wall in one case, whereas videofluoroscopy showed no movement. In one patient, real-time MRI provided additional information by showing an asymmetric movement of the lateral pharyngeal walls that could not be depicted by videofluoroscopy due to technical limitations. Concerning image quality, the coronal plane was more difficult to evaluate with real-time MRI compared to videofluoroscopy. The axial plane was easier to analyze in real-time MRI compared to videofluoroscopy. CONCLUSION: Real-time MRI has the potential to depict the pattern of velopharyngeal closure in close correlation with videofluoroscopy, and may deliver additional information in selected cases.     

Efficacy, safety, and tolerability of sertraline in patients with late-life depression and comorbid medical illness

OBJECTIVES: To report on the efficacy, safety, and tolerability of sertraline in the treatment of elderly depres-sed patients with and without comorbid medical illness. SETTING: Multicenter. DESIGN: Randomized, double-blind, placebo-controlled study. PARTICIPANTS: A total of 752 patients aged 60 and older with diagnosis of major depressive disorder according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis. MEASUREMENTS: Outcome measures included the 17-item Hamilton Depression Scale (HAMD); the Clinical Global Depression-Severity/Improvement (CGI-S/CGI-I); efficacy and safety/adverse event assessments; Quality of Life, Enjoyment, and Satisfaction Questionnaire; and the Medical Outcomes Study 36-Item Short-Form Health Status Survey. RESULTS: In the overall sample, sertraline was superior to placebo on all three primary outcome measures, HAMD, and overall clinical severity and change (CGI-S/CGI-I). Furthermore, therapeutic response to sertraline was comparable in those with or without medical comorbidity, and there were no treatment-by-comorbidity group interactions. Sertraline was also associated with a faster time to response than placebo in the comorbid group (P<.006). Sertraline-treated patients in the comorbid group had similar adverse events and discontinuations when compared to those in the noncomorbid group. CONCLUSION: Sertraline was efficacious in reducing depressive symptomatology, regardless of the presence of comorbid medical illness. Sertraline was safe and well tolerated by patients with or without medical illness.     

Bronchogenic metastasis involving the frontal sinus and masquerading as a Pott's puffy tumour: a diagnostic pitfall

A case is reported of metastatic bronchogenic carcinoma involving the frontal sinus and masquerading as a Pott's puffy tumour. A pathological fracture and persistent lung radiographic changes prompted fine needle aspiration of the mass, which showed a poorly differentiated adenocarcinoma.     

The influence of oral cavity tumour treatment on the voice quality and on fundamental frequency

This study aimed to discover whether the surgical treatment of oral cavity tumours only affects on articulation or whether it also leads to a change in voice quality and fundamental frequency. Twelve participants were examined pre- and postoperatively for mean speaking fundamental frequency, standard deviation of the mean fundamental frequency, harmonic-to-noise-ratio and intrinsic pitch. All the parameters showed a substantial postoperative change in some patients.     

Using oral polio vaccine beyond the cold chain: A feasibility study conducted during the national immunization campaign in Mali

We conducted the first systematic documentation of using oral polio vaccine (OPV) out of the cold chain during national immunization day (NID) campaigns in Mali. Using a crossover intervention design, vaccinators compared the transport of OPV in vaccine carriers with or without ice packs. Vaccine integrity was assured through monitoring vaccine vial monitor (VVM) status. Despite ambient temperatures up to 40 °C, none of the VVMs on any of the vials used (n = 956) reached their discard point. Over 90% of vaccinators and supervisors preferred conducting NIDs without ice packs. In addition, using OPV out of the cold chain reduced vaccine wastage resulting from melting ice packs causing labels to detach from the vial.     

Establishing the feasibility of performance measures for alcohol and other drugs

The Washington Circle (a multiple-disciplinary group of providers, researchers, managed care representatives, and public policy representatives) examined three performance measures for alcohol and other drug (AOD) services. These measures, which were developed and applied to managed care organizations' administrative data for their commercial enrollees, are: (a) identification, the percent of adult enrollees with AOD diagnoses; (b) initiation, the percent of adults with an inpatient AOD admission or with an index outpatient visit for AOD abuse or dependence and any additional AOD services within 14 days of identification; and (c) engagement, the percent of adults diagnosed with AOD disorders that receives two additional AOD services within 30 days of the initiation of care. We conclude that using administrative databases to compare managed care organizations' performance is feasible, meaningful and informative. The article discusses issues in interpreting performance measures in several areas: organizational structure of alcohol and other drug services, information available for measurement, and computational issues.
