Real World Use of Hypertonic Saline in Refractory Acute Decompensated Heart Failure: A U.S. Center's Experience.

OBJECTIVES: The purpose of this study was to investigate real world safety and efficacy of hypertonic saline therapy in cases of refractory acute decompensated heart failure (ADHF) at a large U.S. academic medical center. BACKGROUND: Hypertonic saline therapy has been described as a potential management strategy for refractory ADHF, but experience in the United States is limited. METHODS: A retrospective analysis was performed in all patients receiving hypertonic saline for diuretic therapy-resistant ADHF at the authors' institution since March 2013. The primary analytic approach was a comparison of the trajectory of clinical variables prior to and after administration of hypertonic saline, with secondary focus on predictors of treatment response. RESULTS: A total of 58 hypertonic saline administration episodes were identified across 40 patients with diuretic-therapy refractory ADHF. Prior to hypertonic saline administration, serum sodium, chloride, and creatinine concentrations were worsening but improved after hypertonic saline administration (p < 0.001, all). Both total urine output and weight loss significantly improved with hypertonic saline (p = 0.01 and <0.001, respectively). Diuretic efficiency, defined as change in urine output per doubling of diuretic dose, also improved over this period (p < 0.01). There were no significant changes in respiratory status or overcorrection of serum sodium with the intervention. CONCLUSIONS: In a cohort of patients who were refractory to ADHF, hypertonic saline administration was associated with increased diuretic efficiency, fluid and weight loss, and improvement of metabolic derangements, and no adverse respiratory or neurological signals were identified. Additional study of hypertonic saline as a diuretic adjuvant is warranted.

The role of doxycycline in the management of chronic rhinosinusitis with nasal polyps.

INTRODUCTION: Many theories on the pathophysiology of chronic rhinosinusitis with nasal polyposis (CRSwNP) exist. The most effective management of CRSwNP has not been elucidated. Doxycycline, which has anti-inflammatory and anti-bacterial properties, has shown durable effects; however, its efficacy in combination with standard therapy has not been examined. We hypothesized that its addition to the standard anti-inflammatory regimen would improve patient outcomes. METHODS: We performed a double-blind, placebo-controlled trial at a tertiary level institution. Patients with moderate or severe CRSwNP were randomized into two groups, each receiving a 20-day course of oral corticosteroids and doxycycline or placebo. The 22-item Sinonasal Outcome Test (SNOT-22), nasal polyp scores, and visual analog scale (VAS) scores were recorded at the initial, 3-, 8- and 12-week visits. RESULTS: 49 patients were enrolled, 24 in the experimental and 25 in the placebo group with 3 moderate disease patients in each group. There were 12 dropouts in the treatment group and 14 in the placebo group. The most common reasons for dropout were severe CRS and asthma exacerbations. There was no significant difference in SNOT-22 scores, nasal polyp scores, and VAS scores between the two arms. CONCLUSIONS: Non-surgical management of patients with CRSwNP remains challenging. Our conclusions are limited given the high dropout rate and thus, limited sample size with inadequate power. This study is important, however, because a high dropout rate of mostly severe disease patients may illustrate that this patient population may not be optimally managed with medical therapy alone.

Costs in Pituitary Surgery: Racial, Socioeconomic, and Hospital Factors.

Objective To investigate the influence of patient demographic factors and hospital factors on cost and length of stay in patients undergoing pituitary surgery. Design/Setting A retrospective cross-sectional study of the 2008 to 2012 Nationwide/National Inpatient Sample. Participants Patient demographics and hospital characteristics for patients undergoing pituitary surgery were compared between white, black, and Hispanic patients. Main Outcome Measures Variables associated with increased cost and increased length of hospital stay were ascertained and compared against each racial and ethnic group via multiple linear regression analysis. Results Of 8,812 patients who underwent pituitary surgery, 5,924 (67.2%) patients were white, 1,590 (18.0%) were black, and 1,296 (14.7%) were Hispanic. Patient variables found to be significantly different between racial groups via univariate analysis were age, chronic conditions, gender, income, and primary payer. Hospital variables found to be significantly different were location/teaching status, region, and ownership. Hospitalization cost was significantly lower for whites (-$3,082, 95% confidence interval [CI] -$3,961 to -$2,202) and significantly higher for both blacks ($1,889, 95% CI $842-$2,937) and Hispanics ($2,997, 95% CI $1,842-$4,152). Length of hospital stay was also significantly lower in whites (-1.01, 95% CI -1.31 to -0.72) and significantly higher for both blacks (0.65, 95% CI 0.30 to 1.00) and Hispanics (0.96, 95% CI 0.57-1.35). Conclusions Racial and ethnic factors contribute to differences in hospital utilization and cost for patients undergoing pituitary surgery. Further investigations are necessary to uncover the sources of these disparities in an effort to provide safer and more affordable care to all patients.

Reconstruction of a skull base defect after endoscopic endonasal resection of a pituitary adenoma: Sphenoid mucosal flaps.

This report describes a bilateral sphenoid sinus mucosal flap for the repair of a sellar floor defect and CSF leak following endoscopic endonasal skull base surgery. The key advantage of this technique is enabling the sphenoid mucosal flaps to remain vascularized, which reduces postoperative complications including CSF leakage, recurrent sinusitis, meningitis, encephalitis and pneumocephalus. The use of this technique is a viable and possibly favorable alternative to free grafts in the reconstruction of small to medium sized sellar defects with low flow or absent CSF leaks base surgery.

The price of free tissue transfer after tongue reconstruction: quantifying the risks.

OBJECTIVES/HYPOTHESIS: To evaluate the preoperative variables, mean operative time, morbidity, and mortality associated with reconstruction of partial glossectomy defects. STUDY DESIGN: Retrospective data analysis. METHODS: The National Surgical Quality Improvement Program database was queried for patients having undergone glossectomy procedures. The study sample was split into two groups based on the lack or presence of a flap reconstruction. A total of 1,012 glossectomy patients were identified, with 805 undergoing nonflap reconstruction and 207 undergoing free flap reconstruction. Variables evaluated included wound complications, major and minor morbidity, return to the operating room, mortality, and mean operative time. RESULTS: Patients undergoing free flap reconstruction experienced significantly longer mean operative times (482.1 vs. 183.0 minutes, P < .001), were more likely to return to the operating room (odds ratio [OR] = 2.39, 95% confidence interval [CI] = 1.33-4.29, P = .003), and had higher likelihood of wound complications (OR = 5.78, 95% CI = 2.72-12.26, P < .001), major morbidity (OR = 12.39, 95% CI = 7.02-21.85, P < .001), and minor morbidity (OR = 4.20, 95% CI = 2.12-8.33, P < .001). There was no difference in mortality between groups (OR = 8.62, 95% CI = 0.53-141.7, P = .131). CONCLUSIONS: Free flap reconstruction of glossectomy defects involving up to half of the tongue is associated with increased morbidity and operative time when compared with nonflap reconstruction. Currently available functional outcomes data for tongue reconstruction are poor. Possible functional impairment must be weighed against the associated morbidity when deciding which defects require reconstruction, and the decision to reconstruct should not be taken lightly.

Retrosternal Goiter: 30-Day Morbidity and Mortality in the Transcervical and Transthoracic Approaches.

OBJECTIVE: Retrosternal goiters pose a significant challenge in determining the indications and appropriate approach for surgical removal while limiting postoperative morbidity and mortality. The objective of this study is to use the National Surgical Quality Improvement Program (NSQIP) database to compare outcomes of transcervical and transthoracic approaches for retrosternal goiter removal and to review the literature regarding the varying indications for the 2 surgical approaches. STUDY DESIGN: Administrative database analysis. SETTING: NSQIP database. SUBJECTS AND METHODS: The NSQIP database was queried for all cases of retrosternal thyroid: 2716 patients were included, which represents one of the largest data reviews of patients with retrosternal thyroid pathology who underwent surgery. Data were analyzed to examine morbidity and mortality of the cervical and transthoracic approaches. RESULTS: Patient demographics and preoperative comorbidities were similar between groups. Patients undergoing a transthoracic approach experienced increased rates of unplanned intubations and need for transfusion and length of stay postoperatively. CONCLUSIONS: A transthoracic approach is associated with increased rates of several critical postoperative morbidities, and the data indicate the potential of increased overall mortality. Given equivalent retrosternal extension, a transcervical approach should be attempted whenever anatomically possible, regardless of pathology.

Racial, ethnic, and socioeconomic disparities in pituitary surgery outcomes.

OBJECTIVES/HYPOTHESIS: To investigate the association of race, ethnicity, socioeconomic status, and hospital volume with outcomes in pituitary surgery. STUDY DESIGN: Retrospective cross-sectional study of the 2008-2012 National (Nationwide) Inpatient Sample. METHODS: Patient demographics, hospital characteristics, postoperative complications, and in-hospital mortality for patients undergoing pituitary surgery were compared between white, black, and Hispanic patients. Hierarchal logistic regression analysis was used to assess the association of patient and hospital variables on complication rates. RESULTS: A total of 8,812 patients met the inclusion criteria, and 5,924 (67.2%) patients were white, 1,590 (18.0%) were black, and 1,296 (14.7%) were Hispanic. Black and Hispanic patients were more likely to live in the poorest income areas, be insured with Medicaid, and be treated at lower-volume pituitary surgery centers. Patients with Medicaid had a higher likelihood of complications compared to Medicare patients, whereas patients with private insurance were significantly less likely to experience any complications. Likelihood of complications was significantly higher for patients treated at lower-volume pituitary surgery centers. When controlled for patient and hospital characteristics, regression analysis showed that the likelihood of postoperative complications was higher in black and Hispanic patients compared to white patients. CONCLUSIONS: Racial, ethnic, and socioeconomic disparities exist for outcomes after pituitary surgery. Black and Hispanic patients have worse postoperative outcomes compared to white patients, as well as disproportionate utilization of Medicaid and low-volume pituitary surgery centers. Further investigations are necessary to uncover the sources of these disparities in an effort to provide safer and more affordable care to all patients. LEVEL OF EVIDENCE: 2c.

High-resolution microendoscope imaging of inverted papilloma and normal sinonasal mucosa: evaluation of interobserver concordance.

BACKGROUND: High-resolution microendoscopy (HRME) enables real-time imaging of epithelial tissue. The utility of this novel imaging modality for inverted papilloma has not been previously described. This study examines the ability of otolaryngologists to differentiate between images of inverted papilloma and normal sinonasal mucosa obtained with a HRME. METHODS: Inverted papilloma and normal sinonasal mucosa specimens were stained with a contrast agent, proflavine. HRME images were subsequently captured. Histopathological diagnosis was obtained for each sample. Quality-controlled images were used to assemble a training set. After reviewing the training images, 6 otolaryngologists without prior HRME experience reviewed and classified test images. RESULTS: Five samples of inverted papilloma and 2 normal sinonasal mucosa samples were collected. Four representative images from each specimen were used for the 28-image test set. The mean accuracy among all reviewers was 89.9% (95% confidence interval [CI], 84.3% to 94.0%). The sensitivity to correctly identify inverted papilloma was 86.7% (95% CI, 79.2% to 92.2%), and the specificity was 92.9% (95% CI, 89.0% to 100.0%). The Fleiss kappa interrater reliability score was 0.80 (95% CI, 0.70 to 0.89). CONCLUSION: Inverted papilloma and normal sinonasal mucosa have distinct HRME imaging characteristics. Otolaryngologists can be successfully trained to distinguish between inverted papilloma and normal sinonasal mucosa. HRME is a feasible tool for identification of inverted papilloma. By conducting future in vivo trials, HRME potentially may enable real-time surgical margin determination during surgical excision of inverted papilloma.

Cost of management in epistaxis admission: Impact of patient and hospital characteristics.

OBJECTIVES/HYPOTHESIS: To investigate patient and hospital characteristics associated with increased cost and length of stay in the inpatient management of epistaxis. STUDY DESIGN: Retrospective cross-sectional study of the 2008 to 2012 National (Nationwide) Inpatient Sample. METHODS: Patient and hospital characteristics of epistaxis admissions were analyzed. Multiple linear regression analysis was used to ascertain variables associated with increased cost and length of hospital stay. Variables significantly associated with high cost were further analyzed to determine the contribution of operative intervention and total procedures to cost. RESULTS: A total of 16,828 patients with an admitting diagnosis of epistaxis were identified. The average age was 67.5; 52.3% of the patients were male; 73.3% of the patients were Caucasian; and 70.7% of the hospital stays were government funded. The average length of stay was 3.24 days, and average hospitalization cost was $6,925. Longer length of stay was associated with black race, alcohol abuse, sinonasal disease, renal disease, Medicaid, and care at a northeastern U.S. hospital. Increased hospitalization costs of > $1,000 were associated with Asian/Pacific Islander race; sinonasal disease; renal disease; top income quartile; and care at urban teaching, northeastern, and western hospitals in the United States. High costs were predicted by procedural intervention in patients with comorbid alcohol abuse, sinonasal disease, renal disease, patients with private insurance, and patients managed at large hospitals. CONCLUSION: Although hospitalization costs are complex and multifactorial, we were able to identify patient and hospital characteristics associated with high costs in the management of epistaxis. Early identification and intervention, combined with implementation of targeted hospital management protocols, may improve outcomes and reduce financial burden. LEVEL OF EVIDENCE: 2C.

Research productivity and gender disparities: a look at academic plastic surgery.

OBJECTIVES: The h-index has utility in examining the contributions of faculty members by quantifying both the amount and the quality of research output and as such is a metric in approximating academic productivity. The objectives of this study were (1) to evaluate the relationship between h-index and academic rank in plastic surgery and (2) to describe the current gender representation in academic plastic surgery to assess whether there are any gender disparities in academic productivity. DESIGN: The h-index was used to evaluate the research contributions of plastic surgeons from academic departments in the United States. RESULTS: There were 426 (84%) men and 79 (16%) women in our sample. Those in higher academic ranks had higher h-index scores (p < 0.0005). There was a significant difference in overall mean h-index by gender, where the mean scores were 9.0 and 6.0 for men and women, respectively (p = 0.0005). When analyzed by academic rank, there was a significant difference in academic productivity between men and women in assistant and associate professor positions (6.4 vs 5.1, respectively; p = 0.04). CONCLUSIONS: The h-index is able to objectively and reliably quantify academic productivity in plastic surgery. We found that h-indices increased with higher academic rank, and men had overall higher scores than their female colleagues. Adoption of this metric as an adjunct to other objective and subjective measures by promotions committees may provide a more reliable measure of research relevance and academic productivity in academic plastic surgery.
