Basic Legal Considerations in Starting and Maintaining a Dermatology Practice.

The thrill of starting a dermatology practice can be intoxicating. Starting up a business allows the physician to have their own practice by themselves or with other key individuals to launch the brand and ideas. This article provides guidance on the steps a dermatologist should consider when starting a new practice or adding a new partner. In addition, this article details the tools a physician can use to evaluate the various types of "entities," which are sole proprietorship, general partnership, corporations, and limited liability companies, and examines the 4 primary areas that tend to determine whether the parties are sufficiently aligned for success.

Plant growth regulators interact with elevated temperature to alter heat stress signaling via the Unfolded Protein Response in maize.

Plants are increasingly exposed to high temperatures, which can cause accumulation of unfolded protein in the endoplasmic reticulum (ER). This condition, known as ER stress, evokes the unfolded protein response (UPR), a cytoprotective signaling pathway. One important branch of the UPR is regulated by splicing of bZIP60 mRNA by the IRE1 stress sensor. There is increasing evidence that commercial plant growth regulators may protect against abiotic stressors including heat stress and drought, but there is very little mechanistic information about these effects or about the regulatory pathways involved. We evaluated evidence in the B73 Zea mays inbred for differences in the activity of the UPR between permissive and elevated temperature in conjunction with plant growth regulator application. Treatment with elevated temperature and plant growth regulators increased UPR activation, as assessed by an increase in splicing of the mRNA of the IRE1 target bZIP60 following paclobutrazol treatment. We propose that plant growth regulator treatment induces bZIP60 mRNA splicing which 'primes' plants for rapid adaptive response to subsequent endoplasmic reticulum-stress inducing conditions.

Behind the Curtain: The Nurse's Voice in Assessment of Residents in the Emergency Department.

Introduction: Feedback provides valuable input for improving physician performance. Conventionally, feedback is obtained from attending physicians; however, residents work in close contact with other members of the care team, especially nurses. Nurses may have more opportunity to directly observe trainees. In addition, they may value different behaviors and provide unique feedback. The objective of this study was to examine the nurse's perspective of resident performance in the emergency department. Methods: This was a retrospective, mixed-methods study of nursing assessments of residents using a five-point scale from 1 (unsatisfactory) to 5 (outstanding) and providing comments. Analysis included descriptive statistics of the quantitative assessments and content analysis of the nursing comments by a group of attendings, residents, and nurses. Results: Nurses assessed residents as above expectation or outstanding, especially for the categories of "How would you rate this resident's attitude?" (65%) and "Is this resident a team player?" (64%). Content analysis of the comments yielded nine themes including being kind, communication with nurses, being a team player, work ethic and efficiency, and respect for other team members. Of the comments made, 50% provided positive feedback, and the majority of comments (80%) were determined to be actionable. Conclusion: Our data indicate that nurses provide feedback on residents' kindness, efficiency and communication. These two aspects of interacting in the healthcare setting may not be highlighted in conventional, attending provider feedback, yet they are clearly noted by the nurse's voice.

Smoking is associated with increased complications and readmission following extensor mechanism repair.

PURPOSE: Extensor mechanism injuries are disabling injuries that require prompt evaluation and treatment and complications are often devastating. While smoking has been shown to increase complications following total joint arthroplasty, this relationship has not yet been established in those undergoing extensor mechanism repair. The purpose of this study was to evaluate the risk of smoking on postoperative complications following extensor mechanism repair. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was used to identify patients who underwent an extensor mechanism repair from 2005 to 2016. Patients were stratified by tobacco use, as either "current" or "nonsmokers." A multivariate logistic regression was used to control for demographic and comorbid factors while assessing perioperative complications. RESULTS: 5208 patients were identified, and of these, 843 (16.2%) were current smokers. Smokers were younger, male, and with lower BMIs compared to nonsmokers (p = 0.001, p = 0.003, p = 0.002, respectively). They had a higher rate of surgical complications (OR 1.61, CI 1.02-2.52), including deep surgical site infections (OR 3.27, CI 1.03-10.43) and unplanned return to the operating room (OR 2.001, 1.24-3.23). Smokers were more likely to be readmitted within 30 days of surgery (OR 1.78, OR 1.09-2.90). CONCLUSION: Tobacco use is associated with a 1-2% increase in surgical, but not medical, complications following repair of extensor mechanism injuries. Smokers are at higher risk for deep infections, unplanned return to the OR, and hospital readmission. Identifying these patients preoperatively will allow surgeons to accurately counsel patients on perioperative risks. Counseling in preoperative smoking cessation is valuable for optimizing patient outcomes following extensor mechanism repair. LEVEL OF EVIDENCE: Retrospective comparative study, Level III.

Efficacy of a randomized trial examining commercial weight loss programs and exercise on metabolic syndrome in overweight and obese women.

While commercial dietary weight-loss programs typically advise exercise, few provide actual programing. The goal of this study was to compare the Curves Complete 90-day Challenge (CC, n = 29), which incorporates exercising and diet, to programs advocating exercise (Weight Watchers Points Plus (WW, n = 29), Jenny Craig At Home (JC, n = 27), and Nutrisystem Advance Select (NS, n = 28)) or control (n = 20) on metabolic syndrome (MetS) and weight loss. We randomized 133 sedentary, overweight women (age, 47 ± 11 years; body mass, 86 ± 14 kg; body mass index, 35 ± 6 kg/m2) into respective treatment groups for 12 weeks. Data were analyzed using chi square and general linear models adjusted for age and respective baseline measures. Data are means ± SD or mean change ± 95% confidence intervals (CIs). We observed a significant trend for a reduction in energy intake for all treatment groups and significant weight loss for all groups except control: CC (-4.32 kg; 95% CI, -5.75, -2.88), WW (-4.31 kg; 95% CI, -5.82, -2.96), JC (-5.34 kg; 95% CI, -6.86, -3.90), NS (-5.03 kg; 95% CI, -6.49, -3.56), and control (0.16 kg, 95% CI, -1.56, 1.89). Reduced MetS prevalence was observed at follow-up for CC (35% vs. 14%, adjusted standardized residuals (adjres.) = 3.1), but not WW (31% vs. 28% adjres. = 0.5), JC (37% vs. 42%, adjres. = -0.7), NS (39% vs. 50% adjres. = -1.5), or control (45% vs. 55% adjres. = -1.7). While all groups improved relative fitness (mL·kg-1·min-1) because of weight loss, only the CC group improved absolute fitness (L/min). In conclusion, commercial programs offering concurrent diet and exercise programming appear to offer greater improvements in MetS prevalence and cardiovascular function after 12 weeks of intervention.

Effects of social injustice on breast health-seeking behaviors of low-income women.

PURPOSE: The study uses qualitative research to gain a better understanding of what occurs after low-income women receive an abnormal breast screening and the factors that influence their decisions and behavior. A heuristic model is presented for understanding this complexity. DESIGN: Qualitative research methods used to elicited social and cultural themes related to breast cancer screening follow-up. SETTING: Individual telephone interviews were conducted with 16 women with confirmed breast anomaly. PARTICIPANTS: Low-income women screened through a national breast cancer early detection program. METHOD: Grounded theory using selective coding was employed to elicit factors that influenced the understanding and follow-up of an abnormal breast screening result. Interviews were digitally recorded, transcribed, and uploaded into NVivo 8, a qualitative management and analysis software package. RESULTS: For women (16, or 72% of case management referrals) below 250% of the poverty level, the impact of social and economic inequities creates a psychosocial context underlined by structural and cultural barriers to treatment that forecasts the mechanism that generates differences in health outcomes. The absence of insurance due to underemployment and unemployment and inadequate public infrastructure intensified emotional stress impacting participants' health decisions. CONCLUSION: The findings that emerged offer explanations of how consistent patterns of social injustice impact treatment decisions in a high-risk vulnerable population that have implications for health promotion research and systems-level program improvement and development.

HIV testing in women: missed opportunities.

OBJECTIVE: To investigate opportunities for early human immunodeficiency virus (HIV) testing of women. METHODS: A retrospective cohort study design linked case reports from HIV surveillance to several statewide health-care databases. Medical encounters occurring before the first positive HIV test (missed opportunities) were categorized by diagnosis/procedure codes to distinguish visits that were likely to have prompted an HIV test. Women were categorized as late testers (AIDS diagnosis <12 months from first HIV test date), non-late testers (no AIDS diagnosis during study period or diagnosis of AIDS >12 months of HIV diagnosis), of reproductive age (13-44 years old), and not of reproductive age (>44 years old). Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were used to estimate risk and its statistical significance. RESULTS: Of 3303 HIV-infected women diagnosed during the study period, 2408 (73%) had missed opportunity visits. Late testers (39%) were more likely to be black than white (aOR 1.48, 95% CI 1.12-1.95), be older (>44 years old; aOR 7.85, 95% CI 4.49-13.7), and have >10 missed opportunity visits (aOR 2.17, 95% CI 1.62-2.91). Fifty-four percent of women >44 years old were also late testers. Women >44 years old had lower median initial CD4 counts (p<0.001). The top two procedures were the same for all groups of women but mammography was ranked fourth for women >44 years old and Papanicolau smear was ranked fourth for late testers. CONCLUSIONS: Feasibility and acceptability of routine HIV testing in nontraditional health-care settings, such as mammography and Papanicolau screenings, should be explored to identify late testers and older (not of reproductive age) HIV-infected women.

Vocal outcomes after laser resection of early-stage glottic cancer with adjuvant cryotherapy.

OBJECTIVE: To evaluate the vocal outcomes of patients with early-stage glottic carcinoma undergoing laser resection with adjuvant cryoablative therapy. DESIGN: Retrospective review. SETTING: Tertiary care center. Patients Twenty patients with early-stage glottic carcinoma. Intervention Treatment of early-stage glottic carcinoma with endoscopic carbon dioxide laser resection in conjunction with cryoablation. MAIN OUTCOME MEASURES: Disease-free survival and subjective and objective measures of posttreatment voice quality, based on serial videolaryngostroboscopy. RESULTS: There was 1 local treatment failure, with an overall mean disease-free follow-up of 32.6 months (range, 3-93 months). Carbon dioxide laser resection and cryoablative therapy were associated with a significant improvement in subjective voice quality (P<.001). Long-term dysphonia was uniformly improved vis-à-vis the pretreatment condition, even among patients with the most advanced disease undergoing the widest resections. Posttreatment web formation was not noted among 4 patients with anterior commissure involvement. CONCLUSIONS: Endoscopic laser laryngeal surgery performed in conjunction with cryotherapy for early-stage glottic carcinoma yielded excellent primary site control, while improving subjective and objective measures of voice quality. Combined laser surgery and cryotherapy is a possible alternative to radiotherapy for selected patients with early-stage glottic carcinoma who desire curative therapy, while optimizing vocal outcomes.

Vocal fold healing after laser cordectomy with adjuvant cryotherapy.

OBJECTIVES: To understand the effect of adjuvant cryotherapy on glottic wound healing after endoscopic CO2 laser cordectomy. STUDY DESIGN: Canine acute injury model with videolaryngostroboscopic and histopathologic outcomes analysis. METHODS: Twelve adult male dogs underwent bilateral endoscopic CO2 laser transmuscular cordectomy followed by randomized unilateral endoscopic glottic cryotherapy. The animals were randomly divided into four groups and underwent videolaryngostroboscopy followed by sacrifice at 0, 2, 6, and 12 weeks postoperatively. Three untreated male dogs served as controls. Histopathologic sections were prepared with Alcian blue, Giemsa, hematoxylin-eosin, movat's, Masson's trichrome, and picrosirius stains. RESULTS: Videostroboscopy demonstrated an earlier restoration of glottic volume and a return of mucosal waves among vocal folds treated with combined therapy by 6 weeks posttreatment. The mean depth of inflammatory reaction in the vocal cords treated with combined therapy was 1.07 mm versus 1.15 mm in vocal cords treated with CO2 laser therapy alone. At 2 and 6 weeks postoperatively, combined treatment was associated with a decreased volume of collagen. At 12 weeks postoperatively, combined treatment was associated with greater collagen organization, normalized collagen histoarchitecture, and decreased keratinization. CONCLUSIONS: Adjuvant cryotherapy appears to alter glottis-specific wound healing, leading to decreased and more organized collagen formation and decreased keratinization with a resultant improvement in glottic function, when compared with CO2 laser surgery alone, in an acute canine injury model. Studies in humans are ongoing to further evaluate the clinical potential of cryotherapy on glottic wound healing.

Ultrasonic detection of middle ear effusion: a preliminary study.

OBJECTIVE: To assess the ability to detect and characterize middle ear effusion in children using A-mode ultrasonography. DESIGN: Prospective nonblinded comparison study. SETTING: Tertiary children's hospital. PATIENTS: Forty children (74 ears) scheduled to undergo bilateral myringotomy with pressure equalization tube placement. INTERVENTIONS: Before myringotomy, ultrasound examination of the tympanic membrane and middle ear space was performed on each ear. Afterward, myringotomy was performed and the type of effusion (serous, mucoid, or purulent) was recorded. Pressure equalization tubes were then placed. MAIN OUTCOME MEASURE: Comparison of ultrasound findings with the visual assessment of the type of middle ear effusion present. RESULTS: Of the 74 ears tested, 45 (61%) had effusion on direct inspection. The effusion was purulent in 8 ears (18%), serous in 9 ears (20%), and mucoid in 28 ears (62%). Ultrasound identified the presence or absence of effusion in 71 cases (96%) (P = .04). Ultrasound distinguished between serous and mucoid effusion with 100% accuracy (P = .04). The probe did not distinguish between mucoid and purulent effusion. CONCLUSIONS: Ultrasonography is an accurate method of diagnosing middle ear effusion in children. Moreover, it can distinguish thin from mucoid fluid. Further refinements in probe design may further improve the sensitivity of fluid detection and allow differentiation of sterile vs infectious effusion.

Intratracheal ectopic thyroid tissue: a case report and literature review.

We discuss a case of intratracheal ectopic thyroid tissue (ETT) that was retrieved from the files of the Otorhinolaryngic--Head and Neck Pathology Registry at the Armed Forces Institute of Pathology. The patient was a 54-year-old man who had a history of papillary thyroid carcinoma, which had been treated with a subtotal thyroidectomy. During routine follow-up 4 years later, the patient's primary care physician detected an elevated thyroglobulin level. Further referrals and evaluations revealed that the patient had intratracheal ETT. The patient refused to undergo surgical excision and remains without evidence of recurrent carcinoma. In a MEDLINE literature review, we found only 13 other well-documented cases of intratracheal ETT since 1966; in all but two cases, patients had benign disease. Once the possibility of thyroid carcinoma has been eliminated by histologic examination, intratracheal ETT can be managed by complete surgical excision with the prospect of an excellent long-term clinical outcome.

Evidence of real-world effectiveness of a telephone quitline for smokers.

BACKGROUND: Telephone services that offer smoking-cessation counseling (quitlines) have proliferated in recent years, encouraged by positive results of clinical trials. The question remains, however, whether those results can be translated into real-world effectiveness. METHODS: We embedded a randomized, controlled trial into the ongoing service of the California Smokers' Helpline. Callers were randomly assigned to a treatment group (1973 callers) or a control group (1309 callers). All participants received self-help materials. Those in the treatment group were assigned to receive up to seven counseling sessions; those in the control group could also receive counseling if they called back for it after randomization. RESULTS: Counseling was provided to 72.1 percent of those in the treatment group and 31.6 percent of those in the control group (mean, 3.0 sessions). The rates of abstinence for 1, 3, 6, and 12 months, according to an intention-to-treat analysis, were 23.7 percent, 17.9 percent, 12.8 percent, and 9.1 percent, respectively, for those in the treatment group and 16.5 percent, 12.1 percent, 8.6 percent, and 6.9 percent, respectively, for those in the control group (P<0.001). Analyses factoring out both the subgroup of control subjects who received counseling and the corresponding treatment subgroup indicate that counseling approximately doubled abstinence rates: rates of abstinence for 1, 3, 6, and 12 months were 20.7 percent, 15.9 percent, 11.7 percent, and 7.5 percent, respectively, in the remaining subjects in the treatment group and 9.6 percent, 6.7 percent, 5.2 percent, and 4.1 percent, respectively, in the remaining subjects in the control group (P<0.001). Therefore, the absolute difference in the rate of abstinence for 12 months between the remaining subjects in the treatment and control groups was 3.4 percent. The 12-month abstinence rates for those who made at least one attempt to quit were 23.3 percent in the treatment group and 18.4 percent in the control group (P<0.001). CONCLUSIONS: A telephone counseling protocol for smoking cessation, previously proven efficacious, was effective when translated to a real-world setting. Its success supports Public Health Service guidelines calling for greater availability of quitlines.
