Sciatic nerve endometriosis - The correct approach matters: A case report.

Endometriosis is a chronic inflammatory condition affecting nearly 10-15% of women of reproductive age and most frequently occurs in the pelvis. Extrapelvic endometriosis leading to sacral neuropathy is rare. A 29-year old woman, para 1 (vaginal delivery 8 years previously), presented with worsening right hip and buttock pain radiating to the right leg, resulting in limping and other gait changes due to delayed diagnosis and treatment. A diagnosis of sciatic nerve endometriosis was made based on both clinical and imaging findings. The final diagnosis was confirmed on histopathological examination. Transgluteal excision of the sciatic nerve with concomitant laparoscopy for exploration of the pelvic part of the sciatic nerve and excision of the pelvic endometriosis were undertaken. The operating team included a gynaecologist, an orthopaedic surgeon and a neurosurgeon. Postoperative recovery was uneventful and physiotherapy was started. Pain and gait improved. Endometriosis of the sciatic nerve should be suspected if a patient complains of cyclical sciatica. Magnetic resonance remains the imaging modality of choice. This case report illustrates the benefit of a multidisciplinary approach.

Does Direct Surgical Decompression After Traumatic Spinal Cord Injury Influence Post-Traumatic Syringomyelia Rates? An 18-Year Single-Center Experience.

OBJECTIVE: Risk factors for post-traumatic syringomyelia (PTS) development after traumatic spinal cord injury (tSCI) are incompletely understood. This study aimed to investigate the influence of direct surgical decompression after tSCI, as well as demographic, clinical, and other management-related factors, on rates of PTS development. METHODS: A single-center case-control study was conducted on patients who presented with tSCI to a tertiary referral center over an 18-year period and received adequate follow-up. Cases were defined by both clinical suspicion and radiologic evidence of PTS. Demographic, clinical, and management-related data were collected and a multivariable logistic regression analysis performed. RESULTS: A total of 286 patients were analyzed, of whom 33 (11.5%) demonstrated PTS. Direct surgical decompression with or without stabilization was performed in 190 of 286 patients, stabilization alone in 47, and non-surgical management in 49. On multivariable analysis, no significant influence on PTS risk was demonstrated for method of acute management (P > 0.05). A ten-year increase in age at injury was shown to decrease PTS rates by 0.72 (P = 0.01). Neurologically complete injury was associated with an increased rate of PTS, though this association did not achieve significance (P = 0.08). When only surgically managed patients were considered (n = 237), no significant influence on PTS rates was demonstrated for anterior decompression (adjusted odds ratio = 1.13, 95% CI = 0.34-3.74, P = 0.84) and for stabilization alone (adjusted odds ratio = 1.19, 95% CI = 0.39-3.61, P = 0.76) relative to posterior decompression. CONCLUSIONS: Direct surgical decompression after tSCI was not demonstrated to significantly influence rates of PTS development. Age at injury and severity of injury should be considered as risk factors for PTS on follow-up.

The use of radiolucent pedicle fixation in degenerative lumbar spine surgery.

Radiolucent pedicle screw fixation has become popularized in the field of oncological spine surgery owing to its ability to provide superior post-operative planning for adjuvant radiotherapy and radiological monitoring of tumour progression. We present the case of a 45-year-old female with degenerative spine pathology who underwent L4/5 and L5/S1 posterior lumbar interbody fusion with carbon fibre reinforced-polyetheretherketone pedicle screw fixation. The authors highlight the potential advantages of radiolucent pedicle fixation, which may translate into the degenerative spine surgery domain.

Use of machine learning to model surgical decision-making in lumbar spine surgery.

PURPOSE: The majority of lumbar spine surgery referrals do not proceed to surgery. Early identification of surgical candidates in the referral process could expedite their care, whilst allowing timelier implementation of non-operative strategies for those who are unlikely to require surgery. By identifying clinical and imaging features associated with progression to surgery in the literature, we aimed to develop a machine learning model able to mirror surgical decision-making and calculate the chance of surgery based on the identified features. MATERIAL AND METHODS: In total, 55 factors were identified to predict surgical progression. All patients presenting with a lumbar spine complaint between 2013 and 2019 at a single Australian Tertiary Hospital (n = 483) had their medical records reviewed and relevant data collected. An Artificial Neural Network (ANN) was constructed to predict surgical candidacy. The model was evaluated on its accuracy, discrimination, and calibration. RESULTS: Eight clinical and imaging predictive variables were included in the final model. The ANN was able to predict surgical progression with 92.1% accuracy. It also exhibited excellent discriminative ability (AUC = 0.90), with good fit of data (Calibration slope 0.938, Calibration intercept - 0.379, HLT > 0.05). CONCLUSION: Through use of machine learning techniques, we were able to model surgical decision-making with a high degree of accuracy. By demonstrating that the operating patterns of single centres can be modelled successfully, the potential for more targeted and tailored referrals becomes possible, reducing outpatient wait-list duration and increasing surgical conversion rates.

Postpartum readmission and uninsurance at readmission for Medicaid vs privately insured births.

BACKGROUND: Routine postpartum care is essential for managing pregnancy complications, like hypertension and diabetes, or screening for new conditions, such as depression. Insurance coverage can impact women's ability to access these postpartum services, with women who change or lose insurance postpartum having a lower likelihood of receiving the recommended postpartum care. Pregnancy-related Medicaid eligibility is only federally guaranteed for a minimum of 60 days after birth, creating the potential for publicly insured women to lose their insurance and their access to postpartum care. OBJECTIVE: The objective of this study was to examine the rates of postpartum readmission and predictors of uninsurance at readmission before and after 60 days postpartum for Medicaid vs privately paid births. STUDY DESIGN: This was a retrospective cohort study in which data from the 2017 Nationwide Readmissions Database were used. Women who delivered with Medicaid or private insurance between January 2017 and June 2017 were included. Potential readmissions that were identified between 0 and 180 days after their childbirth hospitalization were included. The primary outcomes of interest were postpartum readmission and delivery payer at postpartum readmission, evaluated at 30-day intervals up to 180 days postpartum. Multivariable logistic regressions were used to determine the association of the risk for readmission and the risk for being uninsured at the time of readmission with insurance provider at the time of delivery. The analysis was also conducted for a subset of acute-cause readmissions or those not likely to be related to chronic or preexisting medical conditions. RESULTS: A total of 24,719 (2.7%) patients were readmitted within 180 days after delivery: 14,179 (54.1%) had Medicaid delivery insurance and 10,540 (40.2%) had private insurance at delivery. Readmission rates decreased over the time intervals after delivery for both delivery payer types, but were consistently higher for those with Medicaid. The rate of uninsurance at readmission increased more with each postpartum month for those with Medicaid than for those with private insurance at delivery: from 0.9% (95% confidence interval, 0.7-1.1) at 0 to 30 days to 9.7% (95% confidence interval, 8.1-11.6) at 150 to 180 days postpartum for those with Medicaid and from 0.2% (95% confidence interval, 0.1-0.4) at 0 to 30 days to 2.6% (95% confidence interval, 1.6-4.1) at 150 to 180 days postpartum for those with private insurance. Medicaid coverage at the time of delivery was a significant predictor of being readmitted (adjusted odds ratio, 1.86; 95% confidence interval, 1.75-1.97) and uninsured at the time of readmission (adjusted odds ratio, 3.99; 95% confidence interval, 2.88-5.52) when compared with being privately insured. Findings were similar for the acute-cause readmissions. CONCLUSION: Women with Medicaid at delivery have a higher risk for readmission and uninsurance at readmission than privately insured women beyond 60 days postpartum. This analysis provides further evidence of the insurance instability women face in the postpartum period, especially by those insured by Medicaid at the time of delivery, and should promote discussions among policymakers, payers, and providers on strategies to ensure coverage and access to care for women and their families after childbirth. For states considering to expand their eligibility criteria to 1 year postpartum, this study provides evidence on the vulnerabilities and unique risks that women with Medicaid face after 60 days postpartum.

Shoulder Injury Following Overzealous Manipulation in Adhesive Capsulitis by Untrained Professional Managed with Shoulder Arthroscopy.

Introduction: Adhesive capsulitis of shoulder is a commoner condition in middle aged population and is classified into primary and secondary types based on etiology. Treatment options depend on stages of disease which ranges from physical therapy, non-steroidal anti-inflammatory medications, intra-articular steroid injection, hydro-dilatation therapy, manipulation under anesthesia, and arthroscopic capsular release. However, the condition is generally mismanaged by untrained professionals in the periphery center leading to complications. We report one such case, which was then managed arthroscopically. Case Report: A 58-year-old female patient presented to our outpatient department with a severe painful left shoulder following overzealous manipulation by untrained professional and she was diagnosed with severe traumatic capsulosynovitis with a subscapularis tear, biceps tendon subluxation, and shoulder subluxation. We managed patient arthroscopically with extensive capsulosynovectomy, biceps tenotomy, and upper subscapularis repair. Postoperatively, she was immobilized for 6 weeks and was put on proper rehabilitation program. At the 2-year follow-up, the patient had an excellent outcome and had complete pain-free movements at the left shoulder with significant increase in pre-operative constant shoulder score of 12-82. Conclusion: ?Overzealous manipulation shoulder in frozen shoulder patients has serious complications and has to be avoided and therefore has to be done by trained professional gently under anesthesia. Shoulder arthroscopy plays a pivotal role in managing such complications successfully.

Congress ends surprise billing: implications for payers, providers, and patients.

Compromise over ending surprise billing had consistently hit a deadlock as providers, payers, and patient groups found themselves at odds over mechanisms to resolve payment. The COVID-19 pandemic, however, accelerated legislative action on health care proposals, leading to the last-minute passage of the No Surprises Act at the end of 2020. The law marks a rare bipartisan success that promises to secure patient protections while also adding price transparency tools. Importantly, it creates an independent dispute resolution process that balances the demands of payers and providers in negotiating surprise billing. While the cost implications of this process will not be known until after implementation in 2022, it creates a template for states to emulate. Furthermore, it will reorient the relationships among payers and provider groups that have historically relied on out-of-network billing. This new competitive reality is an important step for consumer financial protection in health care.

A 62-Year-Old Man with Acute Alcohol Withdrawal and Stress-Induced Cardiomyopathy.

BACKGROUND Stress-induced cardiomyopathy is also known as takotsubo cardiomyopathy, broken heart syndrome, and left ventricular apical ballooning syndrome. Patients may present with chest pain and electrocardiogram (EKG) changes, but without coronary artery occlusion, and a reduced ejection fraction that may undergo spontaneous reversal if the patient receives appropriate hemodynamic support. This is a case report of stress-induced cardiomyopathy associated with alcohol withdrawal in a 62-year-old man. CASE REPORT We present the case of 62-year-old man who came to the emergency room on account of nausea and vomiting after a reduction in the daily intake of alcohol. He had no chest pain or shortness of breath but had new T wave inversions in anterolateral leads on EKG, elevated troponin, and apical wall hypokinesis with ejection fraction 40% on echocardiography. He subsequently developed active symptoms of alcohol withdrawal and was managed with intravenous Lorazepam and chlordiazepoxide. With the improvement in his mental state over the next couple of days, he had a coronary angiogram which showed no coronary disease. He was diagnosed with stress-induced cardiomyopathy or takotsubo cardiomyopathy due to alcohol withdrawal. CONCLUSIONS This report describes a case of takotsubo cardiomyopathy, or stress-induced cardiomyopathy, that was believed to be associated with acute alcohol withdrawal, with spontaneous improvement in the reduced left ventricular ejection fraction following medical support.

The use of radiolucent (carbon fibre-reinforced polymer) pedicle screw fixation for serial monitoring of clear cell meningioma: a case report.

Clear cell meningioma is an uncommon variant of meningioma associated with high rates of local recurrence and metastasis. However, monitoring for local recurrence may be complicated by metal-related artefacts generated by spinal instrumentation. We present a patient with recurrent lumbar atypical clear cell meningioma, which had been resected multiple times throughout her adolescence. Due to extensive bone and ligament resection, posterior stabilization of the lumbar spine with pedicle screws was required. To ensure clear postoperative visualization of the spinal cord for local recurrence, a carbon fibre/polyetheretherketone (CF/PEEK) pedicle screw and rod construct was used. CF/PEEK has non-inferior biomechanical and biocompatible properties to titanium, with a clear advantage of radiolucency to assist in detecting the local recurrence early and facilitating accurate radiotherapy planning.

Private Equity Investments in Women's Health and Obstetrics and Gynecology Practices.

Private equity has evolved into a major force in health care, with deal values and volumes rising year-over-year as these firms purchase hospital systems and physician groups. Historically, these investors have played an outsized role in highly reimbursed specialties such as dermatology and anesthesia. Private equity is relatively new to women's health; when it has invested in this sector, it has typically done so in fertility services. In recent years, however, private equity firms have ventured into general obstetrics and gynecology, drawn by its promise of steady returns, its fragmented landscape, and the potential to integrate related laboratory, ultrasound, and fertility services into obstetric care. Obstetrics and gynecology practices may soon face the prospect of acquisition by private equity firms offering professional management, centralized back-office functions, streamlined customer service, and the capital needed to reach a broader patient base. However, physicians may have concerns about the tradeoffs that accompany private equity acquisitions. Private equity-owned practices have been known to increase the use of lucrative services, deploy advanced practice professionals in place of physicians, and circumvent conflict-of-interest laws, potentially distorting clinical care and driving up costs for consumers. Furthermore, firms generally aim to exit their investment within a 3- to 7-year timeframe, and short-term growth plans may leave physician-owners with uncertain long-term management. As private equity makes headway into women's health, physicians and policymakers must pay closer attention to how this activity can change practice patterns and transform local health care markets while also demanding transparency in the process.

The removal of cranial springs used in the treatment of scaphocephaly: A minimal access approach.

The treatment of non-syndromic scaphocephaly with spring-activated cranioplasty offers acceptable outcomes with the potential for reduced surgical morbidity when compared with cranial vault remodelling procedures. A disadvantage of this technique is the need for a second operative intervention to remove the implanted devices. There are many descriptions of the surgical technique for performing spring-activated cranioplasty available in the literature; however, little is documented regarding the procedures used for device removal. The published accounts of spring removal demonstrate a wide range of approaches, from the reopening and dissection of the entire previous surgical field, to attempts to limit the incisions and dissection. In this study we describe our technique for the minimally invasive removal of cranial springs used in the treatment of scaphocephaly. Our technique focuses on minimal soft tissue disruption and uses a Kirschner wire cutter to divide the spring at its mid-point so as to relieve any residual internal forces acting on the footplates.

Subclinical Burden of Coronary Artery Calcium in Patients With Coarctation of the Aorta.

Coronary computed tomography (CT) angiography is often performed in adults with coarctation of the aorta (CoA) for anatomic assessment. As this population ages, assessment of atherosclerotic cardiovascular disease burden is important. Thus, quantitative and qualitative coronary artery calcium (CAC) scores were assessed for patients with CoA ≥16 years of age, who were seen at a referral center. CoA patients had either coronary CT angiography or chest CT with interpretable coronary information performed for clinical indications (follow-up, preoperative, or for symptoms) from 2004 to 2017. Qualitative CAC was determined based on low-dose CT and lung cancer screening protocols. Quantitative CAC scores were compared with an age- and gender-matched control cohort of patients chosen from an emergency department database of patients who received coronary CT angiography for chest pain evaluation. Atherosclerotic cardiovascular disease 10-year predicted risk scores were calculated for both cohorts. Out of 131 patients with CoA (mean age 46.1 ± 15.3 years), 22 patients (17%) had multivessel atherosclerotic disease on qualitative assessment. In the subgroup of patients ≥40 years, those with CoA were more likely to have a quantitative CAC score ≥400 compared with those without CoA (14% vs 4%, p = 0.02). Median atherosclerotic cardiovascular disease risk score was 8% (interquartile range 2% to 12%) for CoA patients ≥40 years, and 5% (interquartile range 2% to 9%) for patient without CoA ≥40 years. In conclusion, we determined that CoA patients have subclinical atherosclerosis identifiable on CT in high rates when compared with patients without CoA. Atherosclerotic cardiovascular disease should be assessed in these patients for prevention and treatment.

Mobile health apps preferences and practice among ambulatory cardiovascular patients.

AIM: To determine if patients in cardiology practices would be interested in or willing to use mobile health technologies. METHODS: Patients seen at an ambulatory cardiology clinic for any indication were included. A paper survey was administered during pre-intake that assessed frequency of use, familiarity with and interest in mobile health applications. Data were analyzed using an exploratory logistic regression analysis to determine demographic predictors for technology utilization. RESULTS: A total of 306 patients were included (a plurality, 39.3%, in age group 50-69; 62.7% male). Those from median household incomes between US$30,000 and US$74,999 and those 18-29 years old were more likely to have used a health app (0.53 and 1.21, respectively). Those between 18 and 29 years were less interested in virtual visits with their healthcare provider (-0.92) and those over age 70 were less comfortable using their phone apps (-0.80). CONCLUSION: Age and income are important predictors of mobile health app adoption.

In vitro Evaluation of Shear Bond Strength of Orthodontic Brackets Bonded with Different Adhesives.

BACKGROUND: There is necessary of dry operating field for bonding of orthodontic brackets. The presence of moisture can alter the bond strength. Hence, the aim of the present study was to evaluate the shear bond strength of orthodontic brackets with different adhesives. MATERIALS AND METHODS: In this in vitro study, a total of 100 orthodontically extracted premolars with sound crown structure were divided into 4 equal groups of different primers. Bonding on the buccal surface of all teeth was done after acid etching with upper premolar brackets using different primers followed by light curing. Shear bond strength was evaluated with or without salivary contamination with both adhesives. A shear force for deboning the bracket was done with universal testing machine. The debonded specimens were examined at ×10 magnification to check site of bond failure and remaining adhesive on tooth using adhesive remnant index (ARI). The obtained data were statistically evaluated using SPSS 20 for Windows (SPSS Inc., Chicago, IL, USA) using ANOVA, Kolmogorov-Smirnov, and Levene's test at the statistical significance of P < 0.05. RESULTS: Transbond Plus showed higher shear bond strength of 8.92 MPa under dry and 5.65 MPa with saliva contamination over Transbond XT of 7.24 MPa under dry and 2.43 MPa with saliva contamination, respectively. Higher ARI score was found without contamination in both adhesives. CONCLUSION: Transbond Plus hydrophilic resin had good shear bond strength under both dry and contamination condition compared to hydrophobic Transbond XT resin material.

Evaluation of Low-Level Laser Therapy on Orthodontic Tooth Movement: A Randomized Control Study.

BACKGROUND: Fixed orthodontic treatment is time-consuming procedure. Pain is usually associated with orthodontic treatment. The aim of the present study was to evaluate the role of low-level laser therapy (LLLT) on orthodontic tooth movement (OTM) duration and pain perception. MATERIALS AND METHODS: This randomized double-blind splint-mouth controlled clinical study includes 20 (8 males and 12 females) orthodontic patients requiring bilateral canine retraction. Time taken for canine retraction with LLLT (Group A) over control (Group B) quadrant on the same patient was assessed along with pain experience using facial pain scale. The data were tabulated and statistically evaluated using SPSS 20 for windows (Microsoft, Chicago, IL, USA) and t-test with P < 0.05. The difference in pain was evaluated with Wilcoxon signed-rank test. RESULTS: There was no difference in values for age and sex of patient for tooth movement and pain (P > 0.05). There was statistically significant decrease in rate of canine retraction in Group A compared to Group B. There was statistically significant difference for maxillary and mandibular arches in Group A whereas it was not significant in Group B. Pain experience was statistically significant till 2nd day, and after 3rd day, it was not significant between the groups. CONCLUSION: LLLT can reduce the fixed OTM timing and pain experience.

Association Between IDH1 and IDH2 Mutations and Preoperative Seizures in Patients with Low-Grade Versus High-Grade Glioma: A Systematic Review and Meta-Analysis.

BACKGROUND: Patients with brain tumors, particularly gliomas, commonly present with seizures. Higher incidence of seizure has been reported in low-grade gliomas and tumors located within the temporal and insular area. The association between IDH1 and IDH2 mutations with preoperative seizures in glioma and the magnitude of this association in low-grade versus high-grade gliomas are unclear. To clarify this relationship, a systematic review and meta-analysis was performed. METHODS: Following accepted guidelines and systematic review recommendations, electronic searches were performed in journal databases up to May 2017. Data were extracted and pooled via meta-analysis. RESULTS: We compared 782 patients with IDH1 and IDH2 mutations with 803 patients with wild-type IDH1 and IDH2 before surgery. There was a significant difference in seizure incidence between the IDH1 mutation group (61.6%) and wild-type IDH1 group (32.1%) (odds ratio 2.76; 95% confidence interval, 1.26-6.02; I2 = 73%; P = 0.01). Similar findings were observed in analysis of IDH1 and IDH2 mutations (odds ratio 2.74; 95% confidence interval, 1.74-4.33; I2 = 58%; P < 0.0001). The difference remained in both mutation groups (IDH1, IDH1 and IDH2) with grade II gliomas but not with grade III and IV gliomas. Patients with grade II gliomas showed a higher rate of IDH1 and IDH2 mutations and seizures than patients with grade III and IV gliomas. CONCLUSIONS: This study demonstrated a significant association of IDH1 and IDH2 mutations with incidence of preoperative seizures. This association was significant only in patients with low-grade glioma (grade II) and not in patients with higher grade gliomas (grade III and IV).

How immunotherapies are targeting the glioblastoma immune environment.

The diagnosis of glioblastoma remains one of the most dismal in medical practice, with current standard care only providing a median survival of 14.6 months. The need for new therapies is desperately clear. Components of the tumour microenvironment are demonstrating growing importance in the field, given they allow the tumour to utilise pathways involved in autoimmune prevention, something that enables the tumour's establishment and growth. As with many different cancers, the search for a new standard has progressed to the design of immunotherapies, which aim to counteract the immune changes within this microenvironment. Serotherapy, adoptive lymphocyte transfer, peptide and dendritic cell vaccines and a range of other methods are currently under investigation, while intracranial infection has also been researched for its capacity to reverse glioblastoma mediated immunosuppression. Some of these new therapies have shown promise, but it is a long road ahead before their incorporation into glioblastoma standard therapy.
