BACKGROUND

Thyroid cancer incidence is increasing, making it an important public health issue. Many patients use the Internet for health-related decisions. Our purposes were to measure the quality of thyroid cancer surgery information on the Internet, and to identify quality predictors.

METHODS

The 50 most popular thyroid cancer websites from Google, Yahoo, and MSN were identified. A novel 55-point instrument based on current clinical practice guidelines was designed and used by a Delphi panel of 5 "blinded" endocrine surgeons to assess website information. Each website was independently evaluated by two surgeons. Quality was related to website demographic data using the Student's t-test, chi-square, and ANOVA analyses.

RESULTS

Inter-rater reliability for quality scores was excellent (kappa = 0.81). Mean (% of overall quality) score was 21 (38%), and mean score for surgical content was low at 3.5 (29%). Only 50% of sites discussed indications for surgery; 8% length of surgery/anesthesia; 42% the role of lymphadenectomy; 44% recurrent laryngeal nerve injury/hoarseness and 42% hypoparathyroidism as potential complications; 16% recovery; and 20% recommendations for choosing a thyroid surgeon. Only 38% were updated within 2 years. On univariate analysis, no significant associations were found between surgical quality score and website country of origin, currency, sponsorship, authorship, oversight, or references.

CONCLUSIONS

Thyroid cancer surgery websites on the Internet are incomplete and outdated. No predictors of quality were identified. Significant improvement is needed in regulating information about thyroid cancer surgery on the Internet, and surgeons may contribute to this effort.

OBJECTIVE

The purpose of this study was to explore why obstetrician/gynecologists leave academic practice.

STUDY DESIGN

From a sample of 5000 ACOG fellows, we identified obstetrician/gynecologists in faculty positions and those who had left academic practice. These groups were sent a survey to explore aspects of job satisfaction. Relationships between variables were tested using chi2 analyses. Means were computed for each subscale and differences between current and past faculty were tested with a multivariate analysis of variance model.

RESULTS

There was a 65% response rate to the job satisfaction survey for a total of 280 current faculty and 146 previous faculty. There was no difference between the groups in job satisfaction. Faculty rated opportunities for teaching and administration more important as components of job satisfaction. Practitioners who left academics were more likely to be previous junior faculty and generalists.

CONCLUSION

Junior faculty and generalists are more likely to leave academic practice than senior faculty and subspecialists.

Sensory nerve fibres can detect changes in temperature over a remarkably wide range, a process that has been proposed to involve direct activation of thermosensitive excitatory transient receptor potential (TRP) ion channels. One such channel--TRP melastatin 8 (TRPM8) or cold and menthol receptor 1 (CMR1)--is activated by chemical cooling agents (such as menthol) or when ambient temperatures drop below approximately 26 degrees C, suggesting that it mediates the detection of cold thermal stimuli by primary afferent sensory neurons. However, some studies have questioned the contribution of TRPM8 to cold detection or proposed that other excitatory or inhibitory channels are more critical to this sensory modality in vivo. Here we show that cultured sensory neurons and intact sensory nerve fibres from TRPM8-deficient mice exhibit profoundly diminished responses to cold. These animals also show clear behavioural deficits in their ability to discriminate between cold and warm surfaces, or to respond to evaporative cooling. At the same time, TRPM8 mutant mice are not completely insensitive to cold as they avoid contact with surfaces below 10 degrees C, albeit with reduced efficiency. Thus, our findings demonstrate an essential and predominant role for TRPM8 in thermosensation over a wide range of cold temperatures, validating the hypothesis that TRP channels are the principal sensors of thermal stimuli in the peripheral nervous system.

BACKGROUND

Nonpolypoid (flat and depressed) colorectal lesions are increasingly recognized. Their endoscopic removal requires specialized EMR techniques, which are more complex to perform. Outcomes data on EMR of nonpolypoid neoplasms in the United States is needed.

OBJECTIVE

To determine the safety and efficacy of EMR in the resection of nonpolypoid colorectal neoplasms > or = 1 cm.

DESIGN

Retrospective analysis.

SETTING

Veterans Affairs Palo Alto Health Care System.

PATIENTS

Over a 5-year period, patients who underwent EMR for nonpolypoid colorectal lesions > or = 1 cm.

INTERVENTION

A standardized approach that included lesion assessment, classification, inject-and-cut EMR technique, reassessment, and treatment of residual tissue.

MAIN OUTCOME MEASUREMENTS

Complete resection, bleeding, perforation, development of advanced cancer, and death.

RESULTS

A total of 100 patients (125 lesions: 117 flat and 8 depressed) met inclusion criteria. Mean size was 16.7 +/- 7 mm (range, 10-50 mm). Histology included 5 submucosal invasive cancers, 5 carcinomas in situ, and 91 adenomas. Thirty-eight patients (48 lesions) did not receive surveillance colonoscopy: 8 had surgery, 16 had hyperplastic pathology, and 14 did not undergo repeat examination. Surveillance colonoscopy was performed on 62 patients (77 lesions). Complete resection was achieved in 100% of these patients after 1 to 3 surveillance colonoscopies. All patients received follow-up (mean [standard deviation] = 4.5 +/- 1.4 years); none developed colorectal cancer or metastasis.

LIMITATIONS

Single endoscopist, retrospective study.

CONCLUSIONS

A standardized EMR (inject-and-cut) technique is a safe and curative treatment option in nonpolypoid colorectal neoplasms (> or = 1 cm) in the United States.

Tanning device usage is prevalent among adolescents. Few studies have assessed the role of parental influence on children's use of indoor tanning facilities. Our objective was to determine if children's tanning device usage is affected by parental knowledge of risks of indoor tanning or by parental tanning practices. A survey was administered to 160 parents of 328 children at a general pediatrics clinic and 204 parents of 367 children at a pediatric dermatology clinic (parents n=364, children n=695). Over half of all parents and 17% of all teenagers queried had previously used tanning devices. The level of parental knowledge did not predict tanning device usage by their children. However, parental tanning device usage was associated with increased usage by children (p0.05). Children began using tanning devices on average more than 4 years earlier than their parents. Most parents (69%) never wanted their children to use tanning devices, but only 15% of parents had discussed them with their children. Therefore, health providers can provide an important service by initiating discussions about tanning devices. Additional measures, including legislation requiring parental consent for indoor tanning, are needed to reduce tanning device usage by minors.

BACKGROUND

The one-minute preceptor (OMP) model was developed to effectively and efficiently teach learners while simultaneously addressing patient needs. This study was conducted to determine if third- and fourth-year medical students prefer the OMP model over the traditional precepting model and what teaching points they needed from the clinical encounters.

METHODS

Third- and fourth-year students (N = 164) at two medical schools completed a questionnaire and prompts on teaching points in response to viewing two videotaped precepting encounters. Differences between OMP and traditional precepting scores were computed using a factorial repeated measures analysis of co-variance (ANCOVA). Teaching points were coded and counted.

RESULTS

Students preferred the OMP precepting model to the traditional teaching model (p = 0.001). While the desired teaching points changed as the case presentation/discussion progressed, students were most interested in learning about the clinical presentation or natural progression of the disease regardless of teaching model used.

CONCLUSIONS

Students rate the OMP as a more effective model of teaching than the traditional model. The teaching points desired by students change as the case presentation/discussion unfolds.
