Significance of level v lymph node dissection in clinically node positive oral cavity squamous cell carcinoma and evaluation of potential risk factors for level v lymph node metastasis.

Level V lymph node (LN) dissection has been significantly associated with postoperative shoulder dysfunction as a sequel of spinal accessory nerve (SAN) dysfunction. The aim of study was to determine the role of level V LN dissection in clinically node positive (cN+) oral cavity cancer. We have prospectively evaluated 210 patients of oral cavity squamous cell carcinoma (SCC).

A prospective study of prognostic factors for recurrence in early oral tongue cancer.

Background: Tongue cancer is one of the common cancers in head and neck region. Cervical node metastasis is the strongest poor prognostic factor. Other prognostic factors were also said to be of significance.

Effectiveness of trivalent inactivated influenza vaccine in influenza-related hospitalization in children: a case-control study.

Influenza is known to be associated with asthma exacerbation but the effectiveness of the trivalent inactivated flu vaccine (TIV) in children, especially children with asthma, in preventing hospitalization is unknown. We assessed the effectiveness of the TIV in all children and especially children with asthma to prevent hospitalization with influenza. We conducted a nested case control study of all pediatric subjects (6 months to 18 years old) who were evaluated at the Mayo Clinic, Rochester, MN, who had laboratory-confirmed influenza during each flu season from 1999 to 2006 to evaluate the efficacy of TIV in preventing hospitalization.

Flunking asthma? When HEDIS takes the ACT.

Objective: To test several patient-oriented asthma outcome measures and the Healthcare Effectiveness Data and Information Set (HEDIS) measure of appropriate medication for persistent asthma to determine the most useful quality indicator of asthma care.

Design: Prospective mail survey of adult employees and dependents with asthma.

Methods: The medical and pharmacy claims of all subjects from 12 months before and after the survey were abstracted.

Complexity science: core concepts and applications for medical practice.

Complexity science is a useful construct for physicians trying to cope with the escalating sophistication of health care and pressure to control costs. The science of complexity suggests that outcomes are not always linear or predictable. Physicians need to learn to expect unpredictability, respect autonomy and creativity, and be flexible in responding to emerging patterns and opportunities.
