Vestibular Vertigo and Disparities in Healthcare Access Among Adults in the United States.

OBJECTIVE: Vertigo and dizziness have a high lifetime prevalence with significant impacts on daily life. We sought to explore differences in access to and ability to afford care among adults with vestibular vertigo by race/ethnicity, income, and insurance type. DESIGN: This is a cross-sectional study using the 2016 National Health Interview Survey. A total of 32,047 adults who completed the 2016 National Health Interview Survey Balance Supplement were analyzed. We used a previously validated definition of vertigo defined as (1) positional vertigo, (2) rotational vertigo, or (3) recurrent dizziness with nausea and either oscillopsia or imbalance. We examined several self-reported measures of healthcare utilization and access. RESULTS: Among adults with vestibular vertigo, African Americans had significantly increased odds of delayed care due to lack of transportation; Hispanic ethnicity was associated with decreased odds of skipping medication doses and asking a doctor for a lower-cost medication. Adults with public insurance had significantly lower odds of reporting delayed care due to worry about cost, not receiving medical care due to cost, and delayed filling of a prescription, but had greater odds of reporting delayed care due to lack of transportation. Lack of insurance and lower income were associated with increased odds of delaying and not receiving care due to cost. CONCLUSION: These findings demonstrate significant differences in access to care among adults with vestibular vertigo in the United States based on race, income, and health insurance status.

Difference in Perception of Nasal Aesthetic Appearance Between Surgeons and Rhinoplasty Patients: A Single-Center Perspective.

BACKGROUND: Patient satisfaction is an essential outcome measure after a rhinoplasty. Yet it is not known whether the opinions of rhinoplasty patients and surgeons on nasal aesthetic appearance differ. OBJECTIVES: The aim of this study was to determine the differences between patients and surgeons in their perception of nasal aesthetic appearance. METHODS: A retrospective cohort of 300 patients seen in consultation for cosmetic, functional, or combined cosmetic and functional rhinoplasty at a single tertiary care center from June 2017 to June 2020 was studied. Based on preoperative patient images, 6 surgeons with varying levels of expertise assessed nasal aesthetics utilizing a modified Standardized Cosmesis and Health Nasal Outcomes Survey for nasal cosmesis (SCHNOS-C). These scores were then compared to the patient-reported SCHNOS-C scores. RESULTS: The cosmetic, functional, and combined subgroups consisted of 100 patients each. The mean [standard deviation] age was 35.4 [13.7] years and 64% were women. The modified SCHNOS-C scores were well-correlated among the 6 surgeons but showed only weak correlations of 0.07 to 0.20 between patient-reported scores and scores assessed by the surgeons. Compared with the surgeon's scores, patients in the cosmetic subgroup perceived their nasal aesthetic problems to be more severe whereas the those in the functional subgroup perceived their nasal aesthetic problems to be milder compared with the surgeons' assessment. CONCLUSIONS: Our findings suggest that patients and surgeons perceive nasal cosmesis differently. This difference should be considered carefully when planning rhinoplasty or assessing its outcome.

Increase in Lactate Without Change in Nutritive Blood Flow or Glucose at Active Trigger Points Following Massage: A Randomized Clinical Trial.

OBJECTIVE: To investigate changes in nutritive blood flow as well as interstitial glucose and lactate within an active myofascial trigger point (MTrP) following massage. DESIGN: Randomized, placebo-controlled trial. SETTING: Subjects were recruited from the general population; procedures were conducted at a research center affiliated with a university hospital. PARTICIPANTS: Adults (N=25) (18-49y old) with episodic or chronic tension-type headache and an active MTrP in the upper trapezius muscle. INTERVENTIONS: Subjects were randomized to receive a single trigger point (TrP) release massage or sham ultrasound (US) treatment at an active MTrP in the upper trapezius muscle. Microdialysis was used to continuously sample interstitial fluid from the MTrP before, during, and for 60 minutes following intervention. MAIN OUTCOME MEASURES: The primary outcome measure was nutritive blood flow within the MTrP as measured by microdialysis ethanol clearance; secondary measures included dialysate glucose, dialysate lactate, and subject discomfort with the procedures. Pressure-pain threshold (PPT) was determined to assess treatment effectiveness. RESULTS: There was no treatment effect of TrP release massage on nutritive blood flow (P=.663) or dialysate glucose (P=.766). The interaction for lactate was significant indicating that dialysate lactate increased for TrP release massage vs sham US (P=.04); maximum lactate increase over baseline was observed at 60 minutes after TrP release massage (P=.007, 0.128 µM, 95% confidence interval 0.045-0.212). Pain evoked by probe placement into an active MTrP was low. An interaction effect on PPT was significant (P=.005). CONCLUSION: TrP release massage of an active MTrP affected anaerobic metabolism as represented by an increase in dialysate lactate without change in nutritive blood flow or dialysate glucose. The lack of a treatment effect on blood flow is discussed.

Novel Use of Ultrasound Elastography to Quantify Muscle Tissue Changes After Dry Needling of Myofascial Trigger Points in Patients With Chronic Myofascial Pain.

OBJECTIVES: To compare a mechanical heterogeneity index derived from ultrasound vibration elastography with physical findings before and after dry-needling treatment of spontaneously painful active myofascial trigger points in the upper trapezius muscle. METHODS: Forty-eight patients with chronic myofascial pain enrolled in a prospective interventional trial of 3 weekly dry-needling treatments for active myofascial trigger points. Trigger points were evaluated at baseline and at treatment completion using palpation, the pressure-pain threshold, and the mechanical heterogeneity index. Thirty patients were reevaluated at 8 weeks. Trigger points that "responded" changed to tissue that was no longer spontaneously painful, with or without the presence of a palpable nodule. Trigger points that "resolved" changed to tissue without a palpable nodule. The mechanical heterogeneity index was defined as the proportion of the upper trapezius muscle that appeared mechanically stiffer on elastography. Statistical significance for comparisons was determined at P < .05. RESULTS: Following 3 dry needle treatments, the mechanical heterogeneity index decreased significantly for the 38 myofascial trigger points (79% of 48) that responded to treatment. Among these, the baseline mechanical heterogeneity index was significantly lower for the 13 trigger points (27% of 38) that resolved, but the decrease after 3 dry needle treatments did not reach significance. The pressure-pain threshold improved significantly for both groups. At 8 weeks, the mechanical heterogeneity index decreased significantly for the 22 trigger points (73% of 30) that responded and for the 10 (45% of 22) that resolved. The pressure-pain threshold improvement was significant for trigger points that responded but did not reach significance for resolved trigger points. CONCLUSIONS: The mechanical heterogeneity index identifies changes in muscle tissue properties that correlate with changes in the myofascial trigger point status after dry needling.

3-Dimensional (3D) Isotropic MRI of the Shoulder - Advantages Over 2D MRI.

The increasing implementation of high-field MRI scanners and the development of novel imaging techniques have rendered 3D imaging of joints more feasible and efficient than ever. This article describes the current state of 3D MRI of the shoulder and highlights the benefits of the technique over conventional 2D MRI with respect to shoulder derangements.

Reliability of the dial test using a handheld inclinometer.

PURPOSE: The primary purpose of this study was to investigate the intra-tester and inter-tester reliability of the dial test using a handheld digital inclinometer. Additionally, we examined the responsiveness of the test, and side-to-side differences for meaningful comparison. MATERIALS/METHODS: Twenty-four healthy subjects (22.5 ± 2.8 years) participated in the study. The dial test was performed on both knees at 30° and 90° of knee flexion with the subject supine. While maintaining a neutral position of the ankle, an inclinometer was positioned parallel to the medial border of the foot to quantify external rotation of the tibia. Two examiners performed the dial test in a blinded manner. The minimal detectable change across repeated measures and side-to-side difference was calculated. RESULTS: Intra-tester reliability for examiner 1 (E1) was 0.83 at 30° knee flexion and 0.89 at 90° knee flexion. Reliability values for examiner 2 (E2) were 0.86 at 30° and 0.87 at 90° knee flexion. Inter-tester reliability was 0.74 at 30° and 0.83 at 90°. The minimal detectable change (MDC) for E1 at 30° was ±9.4° and ±7.4° at 90°. For E2, the MDC value was ±9.1° at 30° and ±8.3° at 90°. Ninety-five percent limits of agreement for side-to-side difference was 16.1° and 11.3° ° for E1 at 30° and 90° and for E2 13.9° at 30° and 14.1° at 90°. CONCLUSIONS: This instrumented dial test using a handheld digital inclinometer to measure external rotation can be performed with acceptable reliability in the clinical setting. A difference of 10° between two measurements on the same knee suggests that a meaningful change has occurred. For right to left comparison, differences greater than 15° suggest clinical significance. LEVEL OF EVIDENCE: III.

Disparities in access to health care in adults with sinusitis in the United States.

BACKGROUND: Sinusitis can significantly decrease quality of life, is costly in both health care expenditure and lost productivity, and can lead to complications if treatment is delayed. Our objective was to explore disparities in health care access among adults with sinusitis based on sociodemographic factors. METHODS: A total of 32,994 participants (representing 244,838,261 US adults) who completed the 2016 National Health Interview Survey (NHIS) were analyzed, of whom 12.17% were diagnosed with sinusitis at least once in the prior 12 months. Multivariate regression analyses were performed. RESULTS: In regression analyses, female sex (odds ratio [OR], 2.00 [95% confidence interval (CI), 1.79-2.24]; p < 0.001) and older age groups were associated with increased odds of having sinusitis. Within the sinusitis cohort, Asian race (OR, 5.97 [95% CI, 1.61-22.12]; p = 0.008) and Hispanic ethnicity (OR, 6.97 [95% CI, 3.22-15.06]; p < 0.001) were associated with increased odds of obtaining foreign medications. Individuals with Medicaid had decreased odds of delaying care (OR, 0.37 [95% CI, 0.25-0.56]; p < 0.001) or not receiving care due to cost (OR, 0.40 [95% CI, 0.24-0.65]; p < 0.001), but increased odds of delaying care due to transportation barriers (OR, 4.64 [95% CI, 2.52-8.55]; p < 0.001). Uninsured individuals had higher odds for delaying care (OR, 4.97 [95% CI, 3.35-7.38]; p < 0.001) and not receiving care (OR, 5.46 [95% CI, 3.56-8.38]; p < 0.001) due to cost. Income >$100,000 was associated with a nearly 90% reduction in inability to obtain care due to cost (OR, 0.11 [95% CI, 0.05-0.21]; p < 0.001) and an over 99% reduction in inability to obtain care due to transportation issues compared with income < $35,000 (OR, 0.01 [95% CI, 0.00-0.04]; p< 0.001). CONCLUSION: Significant disparities in health care access based on race, health insurance status, and income exist among adults with sinusitis in the United States.

Perceptions of Respect Among Patients With Hearing Loss in the United States.

Hearing loss is a common condition that can lead to disability and significantly impact the quality of life. However, as the literature investigating the relationship between hearing loss and patients' perception of respect within the clinical setting is lacking, we performed a retrospective, cross-sectional analysis of the 2017 National Health Interview Survey to elucidate this interaction. After weights were applied, 16,295,495 patients (mean age: 63.79, standard error: 0.28) with hearing loss were identified. Multivariable logistic regression analyses found that those with self-reported hearing loss were less likely to report being treated with respect by their healthcare providers (odds ratio [OR], 0.766; [95% confidence interval, CI: 0.691-0.848]) and less likely to be asked about their beliefs/opinions about the care that they received (OR, 0.842; [95% CI: 0.774-0.916]), indicating a possible disparity in care. Further investigation is needed to examine how this patient population is treated and how providers can create a more inclusive environment.

Revision Rates of Septoplasty in the United States.

Background: Large-scale studies characterizing septoplasty revision rates are lacking. Objectives: To identify rates of septoplasty revision in the United States. Methods: Patients undergoing initial septoplasty between January 1, 2007 and December 31, 2013 were identified using the IBM® MarketScan® Commercial Database. Patients were excluded if they had nasal vestibular stenosis, rhinoplasty, or costal cartilage grafts for the initial surgery, or did not have either septoplasty, nasal vestibular stenosis, rhinoplasty, and/or costal cartilage grafts for the second surgery. Results: 295,236 patients received an initial septoplasty, and 3213 (1.1%) patients underwent a revision. Among the revision group, 178 (5.4%) patients received a septorhinoplasty, among which 13 (7.3%) required a costal cartilage graft. Older patients were less likely to need revision surgery (RS). Patients in the Northeast and West were significantly more likely than patients in the Midwest to undergo RS. Insurance plans such as comprehensive and point-of-service were associated with greater odds of RS, whereas others such as high-deductible health plans were associated with lower odds. Conclusion: Septoplasty revision rates are relatively low at 1.1% but influenced by age, region, and insurance plan.

Peripheral Activation of Formyl Peptide Receptor 2/ALX by Electroacupuncture Alleviates Inflammatory Pain by Increasing Interleukin-10 Levels and Catalase Activity in Mice.

In the context of the electroacupuncture (EA) neurobiological mechanisms, we have previously demonstrated the involvement of formyl peptide receptor 2 (FPR2/ALX) in the antihyperalgesic effect of EA. The present study investigated the involvement of peripheral FPR2/ALX in the antihyperalgesic effect of EA on inflammatory cytokines levels, oxidative stress markers and antioxidant enzymes in an animal model of persistent inflammatory pain. Male Swiss mice underwent intraplantar (i.pl.) injection with complete Freund's adjuvant (CFA). Mechanical hyperalgesia was assessed with von Frey monofilaments. Animals were treated with EA (2/10 Hz, ST36-SP6, 20 minutes) for 4 consecutive days. From the first to the fourth day after CFA injection, animals received i.pl. WRW4 (FPR2/ALX antagonist) or saline before EA. Levels of inflammatory cytokines (TNF, IL-6, IL-4 and IL-10), antioxidant enzymes (catalase and superoxide dismutase), oxidative stress markers (TBARS, protein carbonyl, nitrite/nitrate ratio), and myeloperoxidase activity were measured in paw tissue samples. As previously demonstrated, i.pl. injection of the FPR2/ALX antagonist prevented the antihyperalgesic effect induced by EA. Furthermore, animals treated with EA showed higher levels of IL-10 and catalase activity in the inflamed paw, and these effects were prevented by the antagonist WRW4. EA did not change levels of TNF and IL-6, SOD and MPO activity, and oxidative stress markers. Our work demonstrates that the antihyperalgesic effect of EA on CFA-induced inflammatory pain could be partially associated with higher IL-10 levels and catalase activity, and that these effects may be dependent, at least in part, on the activation of peripheral FPR2/ALX.

Office-based elastographic technique for quantifying mechanical properties of skeletal muscle.

OBJECTIVES: Our objectives were to develop a new, efficient, and easy-to-administer approach to ultrasound elastography and assess its ability to provide quantitative characterization of viscoelastic properties of skeletal muscle in an outpatient clinical environment. We sought to show its validity and clinical utility in assessing myofascial trigger points, which are associated with myofascial pain syndrome. METHODS: Ultrasound imaging was performed while the muscle was externally vibrated at frequencies in the range of 60 to 200 Hz using a handheld vibrator. The spatial gradient of the vibration phase yielded the shear wave speed, which is related to the viscoelastic properties of tissue. The method was validated using a calibrated experimental phantom, the biceps brachii muscle in healthy volunteers (n = 6), and the upper trapezius muscle in symptomatic patients with axial neck pain (n = 13) and asymptomatic (pain-free) control participants (n = 9). RESULTS: Using the experimental phantom, our method was able to quantitatively measure the shear moduli with error rates of less than 20%. The mean shear modulus ± SD in the normal biceps brachii measured 12.5 ± 3.4 kPa, within the range of published values using more sophisticated methods. Shear wave speeds in active myofascial trigger points and the surrounding muscle tissue were significantly higher than those in normal tissue at high frequency excitations (>100 Hz; P < .05). CONCLUSIONS: Off-the-shelf office-based equipment can be used to quantitatively characterize skeletal muscle viscoelastic properties with estimates comparable to those using more sophisticated methods. Our preliminary results using this method indicate that patients with spontaneous neck pain and symptomatic myofascial trigger points have increased tissue heterogeneity at the trigger point site and the surrounding muscle tissue.

Septoplasty Revision Rates in Pediatric vs Adult Populations.

Importance: Although septal deviations are highly prevalent in the pediatric population and pediatric septoplasties are garnering more discussion, to date, there are no large-scale studies characterizing pediatric septoplasty revision rates. Objective: To identify rates of pediatric septoplasty revision in the US. Design, Setting, and Participants: This retrospective, observational cohort study used administrative claims data from the IBM MarketScan Commercial Database (which contains inpatient and outpatient data for millions of patients and dependents covered by employer-sponsored private health insurance in the US) to identify patients undergoing septoplasty between January 1, 2007, and December 31, 2016. Patients 18 years or younger were included in the study as the pediatric cohort, and patients aged 19 to 65 years were included as the adult cohort for comparison. Patients were excluded if the initial surgery included rhinoplasty, nasal vestibular stenosis, or costal cartilage grafts or if the second surgery did not have nasal vestibular stenosis, septoplasty, rhinoplasty, and/or cartilage grafts. Main Outcomes and Measures: Outcomes included septoplasty revision rate, septoplasty-to-rhinoplasty conversion rate, and associated risks for revision surgery. Collected data were analyzed between January 1 and July 30, 2022. Results: A total of 24 322 pediatric patients (mean [SD] age, 15.7 [2.5] years; 15 121 boys [62.2%]) who underwent an initial septoplasty were identified, of whom 704 (2.9%) received a revision. In the adult cohort of 286 218 patients (mean [SD] age, 41.4 [12.2] years; 162 893 [56.9%] men), 3081 individuals (1.1%) received a revision. Within the pediatric revision group, 66 patients (9.4%) received a rhinoplasty vs 162 (5.3%) in the adult revision group. All pediatric age groups had higher revision rates than the adult population, with the 9- to 13-year-old group having the highest rates of revision (118 of 2763 [4.3%]). Patients in the West and Northeast, along with those with point of service and health maintenance organization health plans, were more likely to receive a revision. Conclusion and Relevance: The findings of this cohort study suggest that pediatric patients are more likely to receive a revision surgery than their adult counterparts. Furthermore, pediatric patients are more likely than adults to receive a rhinoplasty as their revision surgery. These findings provide valuable information that may be used to inform clinical decision-making, although further research is needed to better identify the causes for pediatric septoplasty revision.

The Cost of Return to Play Protocols in Collegiate Athletes Recovering from Coronavirus Disease 2019.

INTRODUCTION/PURPOSE: SARS-CoV-2 infection (COVID-19) can result in myocarditis. Protocols were developed to allow competitive athletes to safely return to play (RTP) after a COVID-19 infection, but the financial impact of these protocols is unknown. Our objective was to determine the differential cost of post-COVID-19 RTP protocols for competitive collegiate athletes. METHODS: This multicenter retrospective cohort study of clinical evaluation of 295 athletes after COVID-19 infection was performed at four institutions with three RTP protocols. Costs were calculated using adjusted Center for Medicare and Medicaid Services pricing. All athletes underwent electrocardiogram and clinical evaluation. A tiered approach performed cardiac imaging and biomarker analysis for major symptoms. A universal transthoracic echocardiogram (TTE) approach performed TTE and biomarkers for all athletes. A universal exercise stress echocardiogram (ESE) approach performed ESE and biomarkers for all athletes. RESULTS: The cost per athlete was $632.51 ± 651.80 ($44,908 total) in tiered group (n = 71), $1,072.30 ± 517.93 ($87,928 total) in the universal TTE group (n = 82), and $1357.38 ± 757.05 ($192,748 total) in the universal ESE group (n = 142) (P < 0.001). Extrapolated national costs for collegiate athletes would be $39 to 64 million higher for universal imaging approaches versus a tiered approach. Only seven athletes had probable/possible myocarditis with no significant difference between approaches. CONCLUSIONS: Cardiac screening in collegiate athletes after COVID-19 infection resulted in significant cost to the health care system. A tiered-based approach was more economical, and a universal exercise echocardiogram group detected slightly more myocardial abnormalities by cardiac magnetic resonance imaging. The clinical consequences of these approaches are unknown.

Intra-operative detection of nodal metastasis in early stage cervical cancer: a survey of the practice patterns of SGO members.

OBJECTIVES: To determine the practice patterns of members of Society of Gynecologic Oncologists (SGO) in different clinical situations involving the intra-operative detection of nodal metastasis in early stage cervical cancer. METHODS: A study questionnaire was mailed to the current members of SGO (n=874). Data were collected using an internet survey database. Frequency distributions were determined, and non parametric tests were performed. RESULTS: Thirty percent SGO members responded (n=274). Only 38.6% routinely performed an intra-operative frozen section evaluation of the lymph nodes. Of these; most (79%) did not abort the radical hysterectomy (RH) for an isolated microscopically positive pelvic lymph node. The likelihood of aborting RH for microscopic nodal involvement increased however with number of positive pelvic lymph nodes (21% with 1, 40% with 2-3, and 61% with >3 positive pelvic lymph nodes), involvement of para-aortic lymph nodes (61%), or bilaterally positive lymph nodes (54%). Similarly, a large number did not complete the RH due to gross involvement of pelvic (45%) or para-aortic lymph node/s (69%). Most (90%) completed the lymphadenectomy before aborting RH. When completing RH, the majority tailored its extent to perform a less radical resection. Variables significantly associated with the likelihood of completing RH in different clinical situations included: location of current practice (West), practice type (private), years in practice (>15 years), and number of cases seen per year (>10/month). CONCLUSION: Practice patterns of SGO members are considerably diverse, which is reflective of the conflicting evidence available in the literature. Well designed studies are required to determine the best overall approach.

Stage IIA1 versus stage IIA2 cervical cancer: does the new staging criteria predict survival?

OBJECTIVE: (1) To determine the correlation of 2008 International Federation of Gynecology and Obstetrics staging system with survival in patients with stage IIA cervical cancer, (2) to elucidate the treatment patterns in stage IIA1 and stage IIA2 cervical cancer, and (3) to investigate whether radical hysterectomy or radiation influenced overall survival. METHODS: Data were extracted from the Surveillance, Epidemiology and End Results database between 1988 and 2005. Statistical analysis used χ test, Kaplan-Meier method, Cox regression, and logistic regression. RESULTS: Of the 560 women, 271 (48.4%) had stage IIA1, and 289 (51.6%) had stage IIA2 cervical cancer. Stage IIA2 patients were younger than stage IIA1 patients (mean age, 49 years vs 54 years; P = 0.01). Stage IIA1, compared with stage IIA2, differed significantly regarding the administration of primary radiation (47.2% vs 64.7%, P < 0.001) and adjuvant radiation (60.5% vs 77.5%, P = 0.006). The following variables were significantly associated with the performance of radical hysterectomy: patient age, 65 years or younger, tumor size, ≤ 2 cm or lesser, high tumor grade, and nonsquamous tumor histology. The incidence of adjuvant radiation after radical hysterectomy was high (48% [tumor size, ≤ 2 cm] to 86% [tumor size, >6 cm]). The 5-year overall survival was not significantly different between stages IIA1 and IIA2 (65.8% vs 59.5%, P = 0.2). Only patient age (P = 0.01), tumor size (P = 0.02), and lymph node status (P = 0.002) were independent predictors of survival. When controlled for other contributing factors, there was no significant difference in survival between patients treated by radical hysterectomy and primary radiation. CONCLUSIONS: The 2008 International Federation of Gynecology and Obstetrics staging criteria is not an independent predictor of survival in stage IIA cervical cancer. Given the equivalent efficacy of radical hysterectomy and radiation, attention should be paid to the high risk of adjuvant radiation in these patients.

Objective sonographic measures for characterizing myofascial trigger points associated with cervical pain.

OBJECTIVES: The purpose of this study was to determine whether the physical properties and vascular environment of active myofascial trigger points associated with acute spontaneous cervical pain, asymptomatic latent trigger points, and palpably normal muscle differ in terms of the trigger point area, pulsatility index, and resistivity index, as measured by sonoelastography and Doppler imaging. METHODS: Sonoelastography was performed with an external 92-Hz vibration in the upper trapezius muscles in patients with acute cervical pain and at least 1 palpable trigger point (n = 44). The area of reduced vibration amplitude was measured as an estimate of the size of the stiff myofascial trigger points. Patients also underwent triplex Doppler imaging of the same region to analyze blood flow waveforms and calculate the pulsatility index of blood flow in vessels at or near the trigger points. RESULTS: On sonoelastography, active sites (spontaneously painful with palpable myofascial trigger points) had larger trigger points (mean ± SD, 0.57 ± 0.20 cm(2)) compared to latent sites (palpable trigger points painful on palpation; 0.36 ± 0.16 cm(2)) and palpably normal sites (0.17 ± 0.22 cm(2); P < .01). Analysis of receiver operating characteristic curves showed that area measurements could robustly distinguish between active, latent, and normal sites (areas under the curve, 0.9 for active versus latent, 0.8 for active versus normal, and 0.8 for latent versus normal, respectively). Doppler spectral waveform data showed that vessels near active sites had a significantly higher pulsatility index (median, 8.3) compared to normal sites (median, 3.0; P < .05). CONCLUSIONS: The results presented in this study show that myofascial trigger points may be classified by area using sonoelastography. Furthermore, monitoring the trigger point area and pulsatility index may be useful in evaluating the natural history of myofascial pain syndrome.

Feasibility of extension of platinum-free interval with weekly bolus topotecan and subsequent platinum retreatment outcomes in recurrent ovarian cancer.

PURPOSE: The goal of this study was to evaluate the outcomes and response in a cohort of patients with presumed platinum-sensitive disease who were subsequently retreated with platinum after receiving weekly bolus topotecan at the time of initial recurrence. METHODS: A retrospective review of our institutional databases identified a cohort of platinum-sensitive women with recurrent ovarian and peritoneal carcinoma. Antitumor responses and toxicities were assessed for patients retreated with platinum-based chemotherapy following weekly bolus topotecan (4 mg/m²). RESULTS: Twenty-six patients (median age 63 years, range 45-80 years) were identified. Advanced stage (III/IV) ovarian carcinoma was most common (96%). Residual disease after primary cytoreductive surgery was less than 1 cm in 65% of the cohort. Platinum retreatment was well tolerated. Grade 3 neutropenia occurred most commonly (8%) without any episodes of grade 4 myelotoxicity. Fatigue (12%) and hypersensitivity reaction (15%) were the most common non-hematologic toxicities during platinum retreatment. Of the 26 patients, 5 (19%) had a complete response, 5 (19%) had a partial response, 10 (39%) had stable disease, and 6 (23%) had progressive disease. Thirty-nine percent of patients with stable or progressive disease during weekly bolus topotecan responded to subsequent platinum retreatment. Response to platinum retreatment, treatment-free interval, and platinum-free interval was significant prognosticators for survival (P < 0.05). CONCLUSION(S): The results of this retrospective analysis suggest that weekly bolus topotecan, as intervening non-platinum, may result in acceptable toxicities and response rates during platinum retreatment in platinum-sensitive relapsed ovarian or peritoneal carcinoma.

Widespread myofascial dysfunction and sensitisation in women with endometriosis-associated chronic pelvic pain: A cross-sectional study.

BACKGROUND: Chronic pelvic pain persists in some women with endometriosis even after lesion removal and optimized hormonal treatment. OBJECTIVE: Characterize the presence and distribution of pain, myofascial dysfunction and sensitisation beyond the pelvis in women with endometriosis-associated chronic pelvic pain. METHODS: Cross-sectional study of 30 women prior to participation in a clinical trial. Evaluation included pain-focused abdominopelvic gynaecologic examination with the identification of pelvic floor muscle spasm. Neuro-musculoskeletal examination assessed paraspinal allodynia and hyperalgesia bilaterally and myofascial trigger points in 13 paired muscles. Pressure-pain thresholds were measured over interspinous ligaments and trigger points. Women completed the body territories element of the Body Pain Index. RESULTS: All women had a pelvic floor muscle spasm that they self-identified as a major focus of pain. Twenty of 30 women described their pelvic pain as focal. However, all demonstrated widespread myofascial dysfunction with low pressure-pain thresholds and trigger points in over two-thirds of 26 assessed regions. Widespread spinal segmental sensitisation was present in 17/30, thoracic in 21/30 and lumbosacral/pelvic in 18/30. Cervical sensitisation manifested as low pressure-pain thresholds with 23/30 also reporting recurrent, severe headaches and 21/30 experiencing orofacial pain. Those reporting diffuse pelvic pain were more likely to have widespread (p = .024) and lumbosacral/pelvic (p = .036) sensitisation and report over 10 painful body areas (p = .009). CONCLUSIONS: Women with endometriosis-associated chronic pelvic pain often have myofascial dysfunction and sensitisation beyond the pelvic region that may be initiated or maintained by on-going pelvic floor spasm. These myofascial and nervous system manifestations warrant consideration when managing pain in this population. Clinicaltrials.gov identifier: NCT01553201. SIGNIFICANCE: Women with endometriosis often have pelvic pain persisting after surgery despite hormonal therapies and these women have regional pelvic sensitisation and myofascial dysfunction. Pelvic floor muscle spasm is a major pain focus in this population. Sensitisation and myofascial dysfunction are widespread, beyond the pelvic region. On-going pelvic floor spasm may initiate or maintain sensitisation. Myofascial/sensitisation manifestations warrant consideration when managing pain in this population.

Validation of tumor size as staging variable in the revised International Federation of Gynecology and Obstetrics stage I leiomyosarcoma: a population-based study.

INTRODUCTION: Tumor size has been introduced as a staging variable in the 2008 International Federation of Gynecology and Obstetrics (FIGO) staging system for stage I leiomyosarcoma. In the prior 1988 FIGO staging system, leiomyosarcoma used the same staging criteria as endometrial cancer including cervical involvement. In this large population-based study, we validate the use of tumor size for purposes of risk stratification among stage I leiomyosarcoma patients. METHODS: Data were extracted from the Surveillance, Epidemiology, and End Results database between 1988 and 2005. Kaplan-Meier log rank and Cox proportional hazards models were used for survival analysis and to identify possible predictors for survival. RESULTS: The identified cohort included 819 women: 158 (19.3%), 2008 FIGO stage IA and 661 (80.7%), 2008 FIGO stage IB leiomyosarcoma. The 5-year overall survival rate was better in stage IA than in stage IB leiomyosarcoma (76.6% vs 48.4%, P < 0.001). Similarly, the 5-year overall survival rates were significantly different (P < 0.001) among women with different tumor size categories: 5 cm or smaller, 5.1 to 10 cm, and larger than 10 cm (76.6%, 52.9%, and 41.9%, respectively). The difference in 5-year overall survival rates between women with and without cervical involvement was significant (28.5% vs 55.3%, P = 0.014). Although age (P < 0.001), cervical involvement (P = 0.014), tumor grade (P < 0.001), tumor size (P < 0.001), performance of salpingo-oophorectomy (P = 0.001), and stage (P < 0.001) were all significant prognostic factors on univariate analysis, only age (P = 0.007), tumor size (P < 0.001), tumor grade (P < 0.001), and performance of salpingo-oophorectomy (P = 0.02) were significant predictors on multivariate analysis. Variables not found significant on univariate analysis (hence excluded from the Cox model) included lymphadenectomy, radiation, and race. CONCLUSIONS: The new staging system using tumor size is better for risk stratification in stage I leiomyosarcoma compared with the 1988 FIGO staging system of endometrial cancer.
