Orthopedists Report High Prevalence of Work-Related Pain and Low Ergonomic Awareness.

The purpose of this study was to determine the prevalence of work-related pain among practicing orthopedic surgeons, quantify knowledge of operating room (OR) and clinic ergonomics, and examine the use of occupational health resources. A survey was distributed, which included orthopedic surgeons from four states and five institutions. Data collected included years in practice, practice setting, orthopedic subspecialty, hours operating per week, days per week exercising, location and significance of pain, occupational health awareness, and use of OR/clinic ergonomics. One hundred ten of 194 surveys (56.7%) were completed, representing all orthopedic subspecialties. Eighty-three surgeons (75.5%) experienced pain because of occupational responsibilities. The lumbar spine, neck, and shoulders were the most affected areas. Seventeen (20.5%) identified this pain as significant. Ten (12.0%) stated that the pain did subjectively affect their OR performance. Hand surgeons had a statistically significant decreased risk of musculoskeletal pain (P=.007), whereas spine surgeons had a statistically significant increased risk of musculoskeletal pain (P=.028). Forty-nine (44.5%) were not aware of any institutional resources available if an injury was sustained at work. Forty-eight (43.6%) were aware of OR ergonomics, with 34 (30.9%) taking steps to make their OR more ergonomic. The vast majority of orthopedic surgeons experience pain as a result of occupational responsibilities. A clear lack of knowledge regarding institutional resources as well as OR ergonomics implementation was identified. Education in training, at the institutional and national levels, would expand surgeon knowledge and promote surgeon health. [Orthopedics. 2023;46(5):280-284.].

Burnout Rates Among General Orthopedic Surgeons and Subspecialists: A Pilot Study.

Burnout among physicians is a syndrome of emotional exhaustion, de-personalization, and reduced sense of personal accomplishment that can negatively affect personal relationships, physician well-being, and patient outcomes. Although burnout rates of up to 50% to 60% among orthopedic surgeons have been reported, no studies have evaluated burnout among orthopedic generalists and subspecialists. The primary goal of this study was to examine the prevalence of burnout among orthopedic disciplines. We conducted a multicenter study from March 2019 through December 2019 involving 149 orthopedists. An abbreviated Maslach Burnout Inventory-Human Services Survey was used to measure burnout. Demographic information, personal characteristics, professional characteristics, family life and spousal support, and depression were also assessed. The mean rate of burnout among all respondents was 62%, whereas 16.77% screened positive for depression. Subspecialties with the highest rates of burnout were oncology (100%), sports medicine (68%), and trauma (63%). Similarly, trauma (50.00%), oncology (40.00%), and general orthopedics (20.00%) had the highest positive depression screening rates. In contrast, shoulder and elbow (50%), pediatric (52%), and foot and ankle (54%) specialists had the lowest rates of burnout, whereas shoulder and elbow (0.00%), spine (0.00%), and sports medicine (6.50%) specialists had the lowest rates of positive depression screening. Older age, higher debt load, and oncology subspecialty were associated with increased burnout risk. This study sought to determine burnout rates within each orthopedic discipline, with a secondary aim of disclosing contributing factors. Trauma and oncology had the highest rates of burnout and positive depression screening. Because this study represents a small orthopedic cohort, larger studies are needed to appropriately manage burnout in the future. [Orthopedics. 2022;45(6):333-339.].

Improvements in sexual function following arthroscopic rotator cuff repair.

BACKGROUND: Three-fourths of Americans are sexually active, and studies show a correlation between sexual activity and good health. Rotator cuff tears and subsequent repairs can cause significant disruption in daily living including sexual activity. Orthopedic surgeons rarely discuss sexual activity with patients. Therefore, patients have little information about expectations, restrictions, and return to sexual activity. The primary goal of this study was to evaluate patient improvement in sexual activity following arthroscopic rotator cuff repair and evaluate factors that affect sexual activity. METHODS: An anonymous 20-item multiple-choice survey was sent to patients > 6 months after arthroscopic rotator cuff repair performed by 7 fellowship-trained orthopedic shoulder and elbow surgeons between March 2018 and May 2019. The survey assessed preoperative and postoperative sexual activity and included questions regarding frequency, pain, positioning, and postoperative injury. RESULTS: A total of 88 patients met the inclusion criteria and completed the survey. Preoperatively, 65% of patients admitted that their shoulder interfered with the quality and/or frequency of their sexual activity, most commonly secondary to an inability to bear weight on the affected arm (31%). Postoperatively, the majority of patients (79%) found it easier to engage in sexual activity, with 35% of patients attributing this to less pain. At 6 weeks postoperatively, 72% of patients returned to sexual activity. The overall trend demonstrated a statistically significant (P < .001) increase in sexual activity frequency as one progressed from his or her operative date. It is interesting to note that 31% of patients removed their sling to engage in sexual activity after surgery, with 7% admitting to aggravating their shoulder or causing significant pain. CONCLUSION: Prior to arthroscopic rotator cuff repair, most patients experience limitations in the quality and/or frequency of their sexual activity secondary to their shoulder. Following surgery, the majority of patients will more easily engage in sexual activity by 6 weeks, with increasing frequency as time progresses from surgery. Many patients are noncompliant with sling wear during sexual activity, and 7% will aggravate their shoulder.

Evaluating a Real World Ban on Menthol Cigarettes: An Interrupted Time-Series Analysis of Sales.

BACKGROUND: Menthol in cigarettes has been shown to increase regular cigarette smoking and nicotine dependence, and decrease success in smoking cessation. Owing to these reasons, in May 2015, the province of Ontario introduced a menthol ban on tobacco products that came into effect in January 2017 prior to a Federal Canadian Ban in October 2017. The objective of this article was to assess the effect of a provincial menthol ban on cigarette wholesale sales in Ontario. METHODS: Wholesale data submitted by tobacco manufacturers to Health Canada pursuant to the federal Tobacco Reporting Regulations from October 2012 to September 2017 were analyzed using interrupted time-series analysis. Changes in sales of cigarettes with and without menthol were estimated, using the province of British Columbia as a comparison. Analyses were seasonally adjusted. RESULTS: Sales of menthol and nonmenthol cigarettes increased from 2013 until the implementation of the 2017 provincial ban. Subsequently, a sharp decline of 55 million menthol cigarettes and 128 million total cigarettes was observed in Ontario. As a comparison, no significant changes were observed in British Columbia. CONCLUSION: This study supports the conclusion that implementation of a menthol ban in Ontario was associated with significant reduction of menthol cigarette sales and total cigarettes sales, compared to British Columbia where there was no provincial menthol ban. This suggests that menthol regulations in jurisdictions with a larger percentage of menthol smokers are likely to be highly effective. IMPLICATIONS: The 2017 menthol ban was associated with significant reduction of menthol cigarette sales and total cigarette sales suggesting that menthol regulations will have important effects on cigarette consumption.

Association of flavoured cigar regulations with wholesale tobacco volumes in Canada: an interrupted time series analysis.

INTRODUCTION: This study examines the association of Federal Canadian regulations passed in 2009 addressing flavours (excluding menthol) in small cigars with changes in cigar sales. METHODS: Quarterly wholesale unit data as reported to Health Canada from 2001 through 2016 were analysed using interrupted time series analysis. Changes in sales of cigars with and without flavour descriptors were estimated. Analyses were seasonally adjusted. Changes in the flavour types were assessed over time. RESULTS: The Federal flavour regulations were associated with a reduction in the sales of flavoured cigars by 59 million units (95% CI -86.0 to -32.4). Increases in sales of cigars with descriptors other than flavours (eg, colour or other ambiguous terms) were observed (9.6 million increase (95% CI -1.3 to 20.5), but the overall level (decline of 49.6 million units (95% CI -73.5 to -25.8) and trend of sales of cigars (6.9 million units per quarter (95% CI -8.1 to -5.7)) declined following the ban. Sensitivity analysis showed that there was no substantial difference in effect over time comparing Ontario and British Columbia, suggesting that other provincial tobacco control legislation was not associated with the changes in levels. Analyses suggested that the level change was sensitive to the specification of the date. CONCLUSION: This study demonstrates that flavour regulations have the potential to substantially impact tobacco sales. However, exemptions for certain flavours and product types may have reduced the effectiveness of the ban, indicating the need for comprehensive, well-designed regulations.

Sleep disturbance associated with rotator cuff tear: correction with arthroscopic rotator cuff repair.

BACKGROUND: Sleep disturbance is a common complaint of patients with a rotator cuff tear. Inadequate and restless sleep, along with pain, is often a driving symptom for patients to proceed with rotator cuff repair. To date, no studies have examined sleep disturbance in patients undergoing rotator cuff repair, and there is no evidence that surgery improves sleep disturbance. HYPOTHESIS: Sleep disturbance is prevalent in patients with a symptomatic rotator cuff tear, and sleep disturbance improves after arthroscopic rotator cuff repair. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 56 patients undergoing arthroscopic rotator cuff repair for full-thickness tears were enrolled in a prospective study. Patients were surveyed preoperatively and postoperatively at intervals of 2, 6, 12, 18, and 24 weeks. Patient outcomes were scored using the Pittsburgh Sleep Quality Index (PSQI), Simple Shoulder Test (SST), visual analog scale for pain (VAS), and single assessment numeric evaluation (SANE). Demographic and surgical factors were also collected for analysis. RESULTS: Preoperative PSQI scores indicative of sleep disturbance were reported in 89% of patients. After surgery, a statistically significant improvement in PSQI was achieved at 3 months (P = .0012; 91% follow-up) and continued through 6 months (P = .0179; 93% follow-up). Six months after surgery, only 38% of patients continued to have sleep disturbance. Multivariable linear regression of all surgical and demographic factors versus PSQI was performed and demonstrated that preoperative and prolonged postoperative narcotic use negatively affected sleep. CONCLUSION: Sleep disturbance is common in patients undergoing rotator cuff repair. After surgery, sleep disturbance improves to levels comparable with those of the general public. Preoperative and prolonged postoperative use of narcotic pain medication negatively affects sleep.

The use of MR-myelography combining flexion and extension imaging in the diagnosis of cervical myelopathy: a case report.

This report describes the use of a non-invasive MR-Myelogram combining flexion and extension views to demonstrate causative factors in cervical myelopathy. Utilizing a new approach to MRI, mimicking an older technique of flexion/extension cervical myelography, we were able to identify the pathology of a patient suffering from progressive cervical myelopathy. We report a patient suffering from progressive multilevel cervical myelopathy due to posterior compression of the spinal cord by an inbuckling ligamentum flavum. Neutral position radiologic assessment failed to reveal any significant spinal cord compression. In this patient, the dynamic MRI and MR-Myelography was critical for demonstrating the posterior compression of the spinal cord by the ligamentum flavum. Flexion and extension MRI images of the cervical spine complemented by non-invasive MR-myelography were obtained. Surgical decompression was indicated based on these additional studies. The use of invasive myelography and in particular, flexion/extension myelography is in decline. MR-myelography combining flexion and extension views can be a useful noninvasive means of studying patients with possible ligamentous hypertrophy and dynamic cord compression.

Racial disparity in risk of preterm birth associated with lower genital tract infection.

The objective of this study was to examine the associations between lower genital tract infection, racial group and preterm birth in the Vaginal Infections and Prematurity Study, a large prospective cohort study conducted between 1984 and 1989. This analysis included 11 910 women enrolled at 23-26 weeks' gestation with equal representation from self-identified African American, Hispanic and white women. Subjects were screened for Chlamydia trachomatis, Trichomonas vaginalis and bacterial vaginosis at study entry, and their pregnancy outcomes were ascertained after delivery. The primary outcome of interest was preterm delivery of a low-birthweight infant (<37 weeks and <2500 g). The associations between lower genital tract infection and preterm delivery of a low-birthweight infant were examined within each racial group, with adjustment for potential confounders using multivariable logistic regression. In this cohort, 6.4% of African Americans, 3.8% of Hispanics, and 4.4% of whites had a preterm delivery of a low-birthweight infant (P < 0.001). Lower genital tract infection was significantly associated with preterm delivery of a low-birthweight infant among African Americans, but not among other racial groups. The proportion of preterm birth associated with lower genital tract infection was 21% among African Americans and 5% among whites. The increase in infection-associated preterm birth among African Americans appears to be related both to an increased prevalence of lower genital tract infection, and also to an increased risk of preterm delivery of a low-birthweight infant in the context of lower genital tract infection.

Barotrauma presenting as temporal lobe injury secondary to temporal bone rupture.

We present the case of a scuba diver who experienced acute ear pain during ascent from a dive. CT imaging was performed because of severe unrelenting headache. Blood and gas was identified within the epidural space of the middle fossa and over the petrous bone, as well as hemorrhage within the adjacent temporal lobe. To the best of our knowledge, this is the first case of CT-documented barotrauma affecting the brain as a result of middle-ear gas rupturing through the tegmen tympani.

Arachnoid cysts with orbital bone remodeling--two interesting cases.

PURPOSE: To describe two cases of arachnoid cyst that altered the bony orbit. METHODS: Case report. RESULTS: Cases of unilateral arachnoid cyst are described in two men, both over the age of 60. The patients were evaluated with computed tomography (CT) scans and in each, an arachnoid cyst in the middle cranial fossa caused bone remodeling with exophthalmos in one. These patients were followed clinically and radiographically over a number of years with no change. CONCLUSION: Arachnoid cysts in the middle cranial fossa have the potential to result in clinically significant proptosis due to bone remodeling of orbital walls. Patients with unexplained proptosis should be evaluated with CT scans to establish the presence of bone remodeling and an arachnoid cyst, which can be confirmed with T2-weighted magnetic resonance imaging (MRI).

Is bacterial vaginosis a stronger risk factor for preterm birth when it is diagnosed earlier in gestation?

OBJECTIVE: It is stated commonly that the earlier in pregnancy bacterial vaginosis is diagnosed, the greater is the increase in risk of preterm birth compared with women without bacterial vaginosis. However, this contention is based on small numbers of women. STUDY DESIGN: In this analysis of 12,937 women who were screened for bacterial vaginosis as part of a previously conducted clinical trial, the odds ratio of preterm birth (<7 weeks of gestation) for asymptomatic bacterial vaginosis-positive versus bacterial vaginosis-negative women was evaluated among women who were screened from 8 to 22 weeks of gestation. RESULTS: The odds ratio of preterm birth among bacterial vaginosis-positive versus bacterial vaginosis-negative women ranged from 1.1 to 1.6 and did not vary significantly according to the gestational age at which bacterial vaginosis was screened. The odds ratio for preterm birth did not vary significantly by gestational age at diagnosis when bacterial vaginosis was subdivided into Gram stain score 7 to 8 or 9 to 10. CONCLUSION: Although bacterial vaginosis was associated with an increased risk of preterm birth, the gestational age at which bacterial vaginosis was screened for and diagnosed did not influence the increase.

Optic nerve sheath meningiomas.

PURPOSE: To study the natural history and growth of optic nerve sheath meningiomas and evaluate their management outcome. DESIGN: Clinicopathologic retrospective noncomparative case series. METHODS: A retrospective study of 88 patients who were treated between 1976 and 1999 at the University of British Columbia and the University of Amsterdam. Clinical reports, imaging studies, and histopathologic findings were reviewed. RESULTS: The mean age at onset of symptoms was 40.3 years, and most were seen in middle-aged females. Patients typically presented with visual loss, frequently associated with optic atrophy or papilledema and occasionally optociliary shunt vessels. On imaging, the optic nerve demonstrated segmental or diffuse thickening of the sheath or globular growth. Calcification was seen in 31% of cases and was associated with slower tumor growth. Tumors with posterior components in the orbit had more frequent intracranial involvement. Intracranial extension was more frequent and had a greater growth rate in younger patients. Irregular margins in the orbit implied local invasion. A presenting visual acuity better than 20/50 correlated with longer preservation of vision. Patients who underwent radiotherapy showed improvement in their visual acuity, and tumor growth was halted. Optic sheath decompression did not preserve vision. En bloc tumor excision was associated with no detectable recurrence in contrast to debulked tumors that recurred. CONCLUSIONS: Meningiomas show characteristic indolent growth. Management therefore should be conservative in most cases. Radiotherapy is indicated in patients with progressive visual deterioration. Surgery, when indicated, should be an en bloc excision.
