Anti-CGRP monoclonal antibodies improve cognitive function in patients affected by chronic migraine complicated with medication overuse-headache

Background: Migraine represents one of the most disabling neurological diseases in the world. This burden is primarily due to recurrent pain episodes, alongside cognitive function impairments that patients may experience. This paper aims to explore the effect of three anti-calcitonin Gene-Related Peptide (CGRP) monoclonal antibodies (mAbs) – erenumab, fremanezumab, and galcanezumab – on the cognitive performance of a sample of patients suffering from migraine using the Montreal Cognitive Assessment (MoCA) questionnaire.Methods: A total of 215 patients suffering from migraine who visited the Modena Headache Center were enrolled. The MoCA questionnaire was filled in by the patients at the baseline and subsequent assessments were conducted at 6 and 12 months thereafter. Additionally, patients were requested to complete the 6-item Headache Impact Test, Migraine Disability Assessment Score, and Hospital Anxiety and Depression Scale every three months.Results: The sample was composed of 82% of female participants and 87% of the enrolled patients were diagnosed with chronic migraine. Following one year of treatment, there was a significant enhancement observed in MoCA scores compared to baseline measurements. Moreover, higher consumption of analgesics, elevated body mass index (BMI), and prolonged chronic migraine history exhibited an inverse correlation with MoCA score improvements after 12 months.Conclusions: Erenumab, fremanezumab, and galcanezumab have proven to be effective in relieving the cognitive impairment associated with migraine after 1 year of treatment. These findings underscore the reversibility of cognitive impairment among migraine sufferers, even among those suffering from chronic migraine, as delineated by the majority of the patients under study. This study revealed that prolonged chronic migraine history, higher baseline analgesic intake, and elevated BMI were all predictive of diminished cognitive enhancements following treatment.

Biomimetic gradient scaffolds for the tissue engineering and regeneration of rotator cuff enthesis.

Rotator cuff tear is one of the most common musculoskeletal disorders, which often results in recurrent shoulder pain and limited movement. Enthesis is a structurally complex and functionally critical interface connecting tendon and bone that plays an essential role in maintaining integrity of the shoulder joint. Despite the availability of advanced surgical procedures for rotator cuff repair, there is a high rate of failure following surgery due to suboptimal enthesis healing and regeneration. Novel strategies based on tissue engineering are gaining popularity in improving tendon-bone interface regeneration. Through incorporating physical and biochemical cues into scaffold design which mimics the structure and composition of native enthesis is advantageous to guide specific differentiation of seeding cells and facilitate the formation of functional tissues. In this review, we summarize the current state of research in enthesis tissue engineering highlighting the development and application of biomimetic scaffolds that replicate the gradient tendon-bone interface. We also discuss the latest techniques for fabricating potential translatable scaffolds such as 3D bioprinting and microfluidic device. While preclinical studies have demonstrated encouraging results of biomimetic gradient scaffolds, the translation of these findings into clinical applications necessitates a comprehensive understanding of their safety and long-term efficacy.

The silent stent ascent: asymptomatic retrograde migration of pancreatic duct stent post-pancreaticoduodenectomy

Transanastamotic stents are used to maintain pancreatic duct patency post Whipple’s procedure to manage postoperative fistulas. We present a rare case of a 54-year-old male who presented with recurrent epigastric pain and vomiting post pancreaticoduodenectomy. Imaging demonstrated incidental pancreatic stent migration through the hepaticojejunostomy into the left biliary tree, without evidence of cholangitis. Pancreatic stent in a Whipple’s procedure, demonstrates benefits in maintaining pancreatic duct patency and reduces pancreatic fistulisation. However, it is associated with potential complications including proximal stent migration into the biliary tree. In our case, the patient remained asymptomatic which makes it a unique case. The necessity of stent removal in asymptomatic cases remains a subject of consideration. However, the endoscopic retrieval is in preference to avoid surgical intervention to avoid the risks and complications of invasive procedures.

Radiofrequency regulation of the sphenopalatine ganglion in managing herpes zoster ophthalmicus neuralgia: A case series.

Trigeminal herpes zoster, which comprises 10% to 20% of cases of herpes zoster, often leads to severe pain in the ophthalmic branches. Current treatments, including drug therapy and minimally invasive interventions, have limitations; accordingly, there is a need to explore alternative approaches. This study aimed to evaluate the efficacy and safety of computerized tomography (CT)-guided pulsed radiofrequency of the sphenopalatine ganglion in patients with intractable trigeminal herpetic pain. Three patients with intractable trigeminal ophthalmic zoster neuralgia were studied. All patients complained of bursts of headache, which occurred at least 10 times a day, usually in the periorbital and frontal regions. Conventional treatments, including oral medications and radiofrequency therapy targeting the trigeminal-semilunar ganglion and supraorbital nerve, could not sufficiently provide relief. Two patients were diagnosed with herpes zoster in the ocular branch of the trigeminal nerve with conjunctivitis, while one patient was diagnosed with postherpetic neuralgia in the ocular branch of the trigeminal nerve. This study employed a novel approach that involved CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion. In all three patients, pain relief was achieved within 1 to 3 days after treatment. During the follow-up, one patient had pain recurrence; however, its severity was ≈ 40% lower than the pretreatment pain severity. The second patient had sustained and effective pain relief. However, the pain of the third patient worsened again after 2 months. The average follow-up duration was 3 months. None of the enrolled patients showed treatment-related adverse reactions or complications. Our findings indicated that CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion was a safe and effective intervention for pain in patients with trigeminal ophthalmic zoster neuralgia, suggesting that it may be a therapeutic option if other treatments fail.

Preoperative diagnosis and safe surgical approach in gallbladder amyloidosis: a case report

BackgroundPreoperative diagnosis of gallbladder amyloidosis is usually difficult. In our case, the patient exhibited gallbladder dyskinesia, which led us to suspect cholecystic amyloidosis. We were able to safely perform surgery before cholecystitis onset.Case presentationA 59-year-old male patient with a history of multiple myeloma and cardiac amyloidosis presented to our hospital with a chief complaint of epicardial pain. Abdominal ultrasonography and computed tomography revealed an enlarged gallbladder and biliary sludge without any specific imaging findings of cholecystitis. After percutaneous transhepatic gallbladder aspiration (PTGBA), the patient experienced recurrent bile retention and right upper quadrant pain. Flopropione was effective in relieving these symptoms. Based on his symptoms and laboratory findings, we diagnosed the patient with dyskinesia of the gallbladder. Considering his medical history, we suspected that it was caused by amyloidosis of the gallbladder. A laparoscopic cholecystectomy was performed. The histopathological examination showed amyloid deposits in the gallbladder mucosa, from the intrinsic layer to the submucosa, and in the peripheral nerves of the gallbladder neck. The patient was discharged on postoperative day 5 and has had no recurrence of abdominal pain since then.ConclusionIn our case, gallbladder dyskinesia symptoms led us to suspect gallbladder amyloidosis. We safely surgically treated the patient before cholecystitis onset.

Severe Residual Pulmonary Stenosis after Surgical Repair of Tetralogy of Fallot: What’s Our Next Strategy?

This case report describes a 25-year-old woman with Tetralogy of Fallot (TOF) who underwent surgical repair at age 15. Eight years later, she presented with recurrent chest pain and was found to have residual severe pulmonary stenosis and regurgitation. This is a complication of TOF repair, particularly when the pulmonary valve is not preserved. The paper discusses the management of TOF, including initial palliative procedures and complete repair surgery. It highlights the long-term complications such as pulmonary valve regurgitation and residual stenosis, both of which may require re-intervention. The importance of long-term follow-up for TOF patients is emphasized.

Radiocarpal Osteochondral Allografts for Wrist Pain Postproximal Row Carpectomy

Abstract Background Surgical options for patients with recurrent wrist pain after salvage procedures, such as proximal row carpectomy (PRC), are limited and primarily result in total wrist arthrodesis (TWA). Osteochondral allografting (OCA) offers an additional option to address refractory wrist pain due to arthritis while preserving some range of motion. Case Description A 65-year-old, right hand dominant male developed chronic wrist pain, secondary to untreated scapholunate and triangular fibrocartilage complex ligament tears. The patient underwent a PRC, radial styloidectomy, and partial wrist denervation with good initial pain relief. Two years later, symptoms returned with radiographs demonstrating capitate sclerosis. A salvage arthroplasty with OCA produced relief of symptoms. Literature Review Refractory wrist pain after salvage procedures have traditionally been managed with TWA or less commonly, wrist arthroplasty. Capitate resurfacing and interposition have expanded indications for PRC. OCA is a chondral replacement procedure that utilizes cadaveric cartilage allograft plugs to replace damaged cartilage in various articular joint surfaces. Although OCA used in the lower extremity and shoulder has demonstrated improved pain relief and return of function, it has not been reported in the wrist. Clinical Relevance There are limited options for refractory wrist pain after salvage procedures. We present an additional alternative to TWA, by resurfacing the radiocarpal joint affected by chondromalacia after a PRC. This option offers another treatment modality for recurrent wrist pain while still preserving some element of range of motion.

Clinical course and predictors of outcome following surgical treatment of benign peripheral nerve sheath tumors, a single center retrospective study

Introduction Peripheral nerve sheath tumors are the most common tumor of the peripheral nerves. In general, surgery has a favorable outcome and is the treatment of choice. However, postoperative neurologic deficits are not uncommon, and predictors of outcome are poorly defined. Objective To evaluate clinical outcomes after surgical treatment of benign peripheral nerve sheath tumors and identify outcome predictors that may affect preoperative decision making and improve surgical outcomes. Method In this single center retrospective study, all patients surgically treated for a benign peripheral nerve sheath tumor between 2005 and 2020 were eligible for inclusion. Medical records and imaging data were reviewed. Studied outcomes were changes in neurological symptoms, pain, and tumor recurrence. Logistic regression was performed to identify possible outcome predictors. Results In total, 81 patients undergoing 85 separate surgeries for benign peripheral nerve sheath tumors were included. The most common preoperative symptoms were local pain (90%) followed by a noticeable mass (78%), radiating pain (72%), sensory deficit (18%) and motor deficit (16%). A postoperative improvement of symptoms was seen in 94% of those with pain, 48% of those with sensory deficits and 78% of those with motor deficits. However, 35% and 9% developed new postoperative sensory and motor deficits, respectively. Multivariable analysis showed complete tumor removal as a predictor of reduced pain (p = 0.033), and younger age and larger tumors were risk factors for persistent or increased sensory deficits (p = 0.002 and p = 0.005, respectively). There were no significant predictors of motor deficits. Neurocutaneous syndromes were associated with increased odds of tumor recurrence on univariable analysis (p = 0.008). Conclusion Surgery of benign peripheral nerve sheath tumors is a safe procedure with a favorable outcome in most cases. Younger age and larger tumors were risk factors for persistent or increased sensory deficits, while complete tumor removal was associated with reduced pain. Patients with neurocutaneous syndromes had a higher rate of tumor recurrence. To further evaluate outcome predictors, we recommend future studies to focus on longer follow-up periods to assess the natural course of postoperative neurological deficits.

Cervicocephalic kinaesthesia reveals novel subgroups of motor control impairments in patients with neck pain

Cervical-spine sensorimotor control is associated with chronicity and recurrence of neck pain (NP). Tests used to measure sensorimotor impairments lack consistency in studied parameters. Interpretation is often based on either a handful or numerous parameters, without considering their possible interrelation. Different aspects of motor-control could be studied with different parameters, but this has not yet been addressed. The aim of this study was to determine if different parameters of cervical position (JPE) and movement (Butterfly) sense tests represent distinct components of motor-control strategies in patients with chronic NP. Principal component analysis performed on 135 patients revealed three direction-specific (repositioning from flexion, extension or rotations) and one parameter-specific (variability of repositioning) component for JPE, two difficulty-specific (easy or medium and difficult trajectory) and one movement-specific (undershooting a target) component for Butterfly test. Here we report that these components could be related to central (neck repositioning and control of cervical movement) and peripheral sensorimotor adaptations (variability of repositioning) present in NP. New technologies allow extraction of greater number of parameters of which hand-picking could lead to information loss. This study adds towards better identification of diverse groups of parameters offering potentially clinically relevant information and improved functional diagnostics for patients with NP.

Reoperation Following Primary Greater Occipital Nerve Decompression Surgery: Incidence, Risk Factors and Outcomes.

Although nerve decompression surgery is an effective treatment for refractory occipital neuralgia (ON), a proportion of patients experience recurrence of pain and undergo reoperation. This study analyzes the incidence, risk factors, and outcomes of reoperation following primary greater occipital nerve (GON) decompression. 215 patients who underwent 399 primary GON decompressions were prospectively enrolled. Data included patient demographics, past medical and surgical history, reoperation rates, intraoperative findings, surgical technique, and postoperative outcomes in terms of pain frequency (days/month), duration (hours/day), intensity (scale 0-10), and migraine headache index (MHI). Bivariate analyses, univariable and multivariable logistic regression analysis was performed. 27 (6.8%) GON decompressions required reoperation with neurectomy at a median follow-up time of 15.5 months (9.8-40.5). Cervical spine disorders on imaging that did not warrant surgical intervention (OR, 4.88; 95% 1.61-14.79; p<0.01) and radiofrequency ablation (RFA) (OR, 4.20; 95% CI, 1.45-15.2; p<0.05) were significantly associated with higher rates of reoperation. At 12 months postoperatively, patients who underwent reoperation achieved similar mean reductions in pain frequency, duration, intensity and MHI, as compared to patients who underwent only primary decompression (p>0.05). Patients with ON who have a history of cervical spine disorders or RFA should be counseled that primary decompression has a higher risk of reoperation, but outcomes are ultimately comparable.

Cost-effectiveness of rimegepant oral lyophilisate compared to best supportive care for the acute treatment of migraine in the UK

Aims Migraine is the most common disabling headache disorder and is characterized by recurrent throbbing head pain and symptoms of photophobia, phonophobia, nausea, and vomiting. Rimegepant 75mg, an oral lyophilisate calcitonin gene-related peptide antagonist, is the first treatment approved for both the acute and preventative treatment of migraine, and the first acute therapy approved in over 20-years. The objective was to assess the cost-utility of rimegepant compared with best supportive care (BSC) in the UK, for the acute treatment of migraine in the adults with inadequate symptom relief after taking at least 2 triptans, or for whom triptans are contraindicated or not tolerated. Materials and methods A de novo model was developed to estimate incremental costs and quality-adjusted life years (QALYs), structured as a decision tree followed by Markov model. Patients received rimegepant or BSC for a migraine attack and were assessed for response (pain relief at 2-hours). Responders and non-responders followed different pain trajectories over 48-hour cycles. Non-responders discontinued treatment while responders continued treatment for subsequent attacks, with a proportion discontinuing over time. Data sources included a post-hoc pooled analysis of the phase 3 acute rimegepant trials (NCT03235479, NCT03237845, NCT03461757), and a long-term safety study (NCT03266588). The analysis was conducted from the perspective of the UK National Health Service and Personal Social Services over a 20-year time horizon. Results Rimegepant resulted in an incremental cost-utility ratio (ICUR) of £10,309 per QALY gained vs BSC, which is cost-effectiveness at a willingness to pay threshold of £30,000/QALY. Rimegepant generated +0.44 incremental QALYs and higher incremental lifetime costs (£4,492). Improved QALYs for rimegepant were a result of less time spent with severe and moderate headache pain. Conclusion This study highlights the economic value of rimegepant which was found to be cost-effective for the acute treatment of migraine in adults unsuitable for triptans.

Three-year follow-up of a novel orthopedic ward fracture liaison services (OWFLS) model.

We established an orthopedic ward fracture liaison services (OWFLS) model and evaluated its role in improving detection rates of bone metabolic markers, treatment rates, and long-term treatability. This observational retrospective cohort study included 120 patients aged >50 years hospitalized for primary osteoporotic fracture from January 2018 to January 2019 (group A: not included in OWFLS). Group B (included in OWFLS) comprised 120 patients from February 2019 to February 2020. We compared rates of bone metabolic index testing, treatment, and adherence; symptomatic improvement; and recurrent fracture between groups. Rates of bone metabolism index testing (50% vs. 0%) and medication use (94.2% vs. 64.2%) were significantly higher after OWFLS implementation. There was no significant difference in adherence rates at 3 months between groups (97.3% vs. 93.5%). Adherence rates at 1 and 3 years were better in group B than A (73.5% vs. 51.9%; 57.5% vs. 26%, respectively). Recurrence of bone pain at 1 and 3 years was significantly lower in group B than A (20.4% vs. 46.8%; 45.1% vs. 76.6%, respectively). OWFLS improved the detection rate of bone metabolism indicators, treatment rate, and patient adherence and reduced recurrence of bone pain. OWFLS may be suitable for settings lacking human resources.

352 Outcomes After Microvascular Decompression for Sole Arterial Versus Venous Compression in Trigeminal Neuralgia

INTRODUCTION: In most cases of trigeminal neuralgia (TN), the trigeminal nerve is compressed by the arterial vasculature. METHODS: We retrospectively reviewed all patients undergoing microvascular decompression at our institution, identifying patients with either sole arterial or venous compression. We dichotomized patients into arterial or venous groups and obtained demographics and postoperative complications for each case. Barrow Neurological Index (BNI) pain scores were collected preoperatively, postoperatively, and at final follow-up, as well as recurrence of pain. Differences were calculated via Chi-squared tests and t-tests. Ordinal regression was used to account for variables known to influence TN pain. Kaplan-Meier analysis was used to determine recurrence-free survival. RESULTS: Of 1044 patients, 642 (61.7%) had either sole arterial or venous compression. 472 of these cases demonstrated arterial compression, and 170 displayed sole venous compression. Patients in the venous compression group were significantly younger (p &lt; 0.001). Patients with sole venous compression demonstrated worse preoperative (p = 0.04) and final follow-up (p &lt; 0.001) pain scores. Patients with sole venous compression had significantly higher rate of pain recurrence (p = 0.02) and BNI score at pain recurrence (p = 0.04). On ordinal regression, venous compression was found to independently predict worse BNI pain scores (OR = 1.66, p = 0.003). Kaplan-Meier analysis demonstrated a significant relationship between sole venous compression and increased risk of pain recurrence (p = 0.03). CONCLUSIONS: TN patients with sole venous compression demonstrate worse pain outcomes following MVD compared to those with only arterial compression.

External assessment of preoperative scores for predicting outcome after microvascular decompression for trigeminal neuralgia.

Recently, two scoring systems have been developed for predicting pain-free outcomes after microvascular decompression (MVD). Evaluation of these scores on large external datasets has been limited. In this study, the authors aimed to evaluate the performance of published MVD scoring systems in predicting pain-free outcome. A total of 458 patients who underwent MVD for trigeminal neuralgia (TN) between 2007 and 2020 and had at least 6 months of follow-up were included in this study. Hardaway and Panczykowski scores were retrospectively computed for each patient and compared with postoperative pain recurrence and pain-free duration. The mean ± SD area under the receiver operating characteristic curve for predicting any pain recurrence after MVD was 0.567 ± 0.081 using the Hardaway score and 0.546 ± 0.085 using the Panczykowski score. On log-rank tests and Kaplan-Meier analysis, the patients with Hardaway scores of 0-2 had significantly shorter pain-free survival times after MVD than did those with a score of 3. Patients with a Panczykowski score of 1 had a significantly shorter pain-free duration after surgery compared with both patients with scores of 2-3 and patients with scores of 4-5. Patients with Panczykowski scores of 2-3 also had significantly shorter pain-free duration compared with patients with scores of 4-5. Both the Hardaway and Panczykowski scores may be useful for predicting postoperative pain-free duration in TN patients, and their utility may be greatest when scores are clustered. Continued refinement of both scoring systems will help to improve our ability to predict patient outcomes after MVD.

460 Frame Navigation Guided Percutaneous Balloon Compression for Intractable Trigeminal Neuralgia Secondary to Multiple Sclerosis

INTRODUCTION: Patients with multiple sclerosis (MS) are more likely to develop trigeminal neuralgia (TN) compared to the regular population, due to scarring of the nerve and the development of a demyelination plaque. Despite treatment, approximately 10% of MS patients treated for TN experience symptom recurrence, including the development of MS-like symptoms such as optic neuritis and bilateral facial pain. METHODS: A computed tomography (CT) scan was performed preoperatively on two patients diagnosed with multiple sclerosis (MS) who experienced secondary trigeminal neuralgia (TN). The acquired images were then introduced into a navigation system for intraoperative navigation. The preliminary CT images were registered using the navigation system and the bony landmarks were set. Fluoroscopy-guided cannulation was performed under general anesthesia to complete the procedure. RESULTS: Two patients diagnosed with multiple sclerosis (MS) who experienced refractory trigeminal neuralgia (TN) underwent percutaneous balloon compression. The patients were 38 and 56 years old and complained of facial pain in the V1-V2 and V3 distribution. Initial conservative treatment and one dosage of Gamma Knife Radiosurgery (GKR) resulted in symptom control for a few weeks. However, both patients had an acute recurrence of pain; thus, percutaneous retrogasserian balloon compression was performed. During follow-up, the patients reported a 70% decrease in pain after the procedure, with minimal recurrence of shooting episodes. CONCLUSIONS: The management of trigeminal neuralgia secondary to drug-resistant multiple sclerosis presents a persistent challenge. The percutaneous technique for retrogasserian balloon compression may offer a solution for some patients, but it can be technically challenging. Microvascular decompression remains a debated approach for this population, given the complexity of the pathogenesis, target identification, and the potential absence of neurovascular conflict, while stereotactic radiosurgery may be a promising alternative.

464 Remote Cognitive Behavioral Therapy Utilizing an In-home Virtual Reality Toolkit (Vx Therapy TM) Reduces Pain, Anxiety, and Depression in Patients With Chronic Cervical and Lumbar Pain: A Potential Opiate Alternative in Multimodal Pain Management

INTRODUCTION: Virtual reality has reduced acute pain through visual and auditory distraction, as well as altered brain neurobiology. VR attenuates pain-induced brain activity without narcotic-related side effects or dependency. Cognitive behavioral therapy (CBT) has demonstrated improved pain-related anxiety, depression, physical disability, resiliency, and quality of life. CBT access remains a challenge in most care communities. METHODS: 145 patients with chronic neck and back pain (63 cervical, 46 non-radicular lumbar, 36 radicular lumbar) enrolled into a 14 week Vx therapy CBT program with therapist guided utilization of an in-home VR system with 50 modules (education, meditation, distraction, entertainment). Pain and anxiety severity scores were recorded before and immediately after VR use as well as time to pain recurrence. PROMIS measures of daily pain intensity, pain behavior, pain interference, anxiety, and depression were recorded at baseline and after 14 weeks of Vx therapy. RESULTS: PROMIS domains were significantly improved after Vx treatment vs baseline for the entire cohort and each subgroup. VR acutely reduced pain during use on average by 33% (p &lt; 0.05) across all 14 weeks lasting a mean 2.5 hours. VR acutely reduced anxiety during use on average by 46% (p &lt; 0.05) across all 14 weeks lasting a mean 2.7 hours. The effect was similar for all three diagnosis groups. CONCLUSIONS: Remote CBT guided in-home VR toolkit (Vx therapyTM) provided effective multi-hour sustained pain relief in patients with chronic neck and back pain with and without radiculopathy. Significant improvement in overall pain, anxiety, and depression and reduced pain interference was observed. This non-invasive, non-pharmaceutical Vx therapy is an ideal option to improve outcomes in post-opioid pain management.

Sciatica after intra articular corticosteroids injection

Background. The intra-articular cortico-steroid (IA-CS) injections treatment are still debatable despite its effectiveness. The failure can cause sciatica which IA-CS injected at the sacroiliac joint (SIJ). The study was done to determine non-technical factors that cause recurrent LBP after optimal SIJ IA-CS injections. Methods. A prospective-clinical study was done that looked at recurring sciatica variables in the cases that received intra-articular injection of CS. Cases were diagnosed with sciatica according to the IASP criteria. All patients had intra-articular CS injections. The numerical rating scale (NRS) was used for rating the pain in the SIJ on a range of (0-10). The scale was reviewed 3, 6, and 9 months post treatment. Age, gender, BMI, trauma history, long-term standing, NSAID used and knee pain were all documented as intra-articular injection treatment possible failure factors. Results. In total, 50 subjects were enrolled, with more females (60%) than males (40%). The mean of age was 55.8±7.4 years. History of trauma was reported in 60%. Long sitting and standing history presented in 70% and 20%, respectively. The recurrence of sciatica affected 30(60%) patients. The right sciatica was affecting more than half of the cases (60%). The vast majority of cases (80%) used NSAID. The pain began within the last three months in 80% of the patients. History of CS injection was recorded in 38% of the cases. Lower limb pain was reported in 80% of the cases. Cases with and without recurrence had the mean age of 55.9 ± 9.5 years and 50.6 ± 14.9 years, respectively. The SIJ pain recurrence is strongly connected with elderly and long sitting in logistic regression analysis. Conclusions. Elderly, NSAID utilize, and uni-lateral sciatica involvement are protective factors against SIJ discomfort recurrence.

Minimally Invasive Interventions on Ganglion Impar in Treatment of Patients with Coccygodynia

Chronic pelvic pain (CPP) is usually treated conservatively, but in patients who do not respond to treatment, ganglion impar (GI) interventions are used as an alternative way to reduce pain. Objective ‒ to study the course of pain syndrome and functional status in patients with coccygodynia (CD) and CPP during the application of minimally invasive interventions on GI. Materials and methods. The analysis of the results of 56 interventions on GI in 50 patients was performed. Inclusion criteria were patients with coccyx pain for ≥3 months aged 23 to 71 years (mean age 47.9±14.8years) who did not respond to conservative treatment methods. 15 (35.7%) of the study participants were male and 27 (64.3%) were female. Interventions were performed on the patients according to five different methods, which were divided into two groups: the first group (n=34) ‒ GI block (GIB) with a local anesthetic and a steroid (patients with CD in whom medical conservative methods of treatment were not effective). The second group (n=14) consisted of persons with recurrent pain syndrome, resistant forms of CD and CPP, including after previously performed steroid injections: n=2 – neurolysis of GI with ethyl alcohol; n=2 – neurolysis of GI by phenol; n=3 – radio frequency modulation of GI; n=7 – radiofrequency ablation of GI. Results. 14.0% of all study participants had post-traumatic CD (history of falling on the coccyx), the vast majority of 86.0% ‒ idiopathic CD. Pain intensity was significantly lower post-intervention compared to baseline VAS mean of 7.6±1.5 cm: 2.5±0.9 cm one-week post-procedure, 1.5±1.9 cm one month, 1.3±1.5 cm three months, 2.1±1.2 cm six months. The average score according to the Karnovsky Scale (KS) before and after the procedure was 73.3±6.3% and 83.9±4.9%, respectively. Conclusions. Interventions on ganglion impar are an effective method of treating patients with coccygodynia of various etiology, which significantly reduce pain according to the VAS scale (p&lt;0.001) and improve the quality of life according to the KS (p&lt;0.001) in dynamics after 1, 3, 6 months. Minimally invasive interventions on ganglion impar make it possible to reduce tissue trauma, to quickly recover for patients after the procedure, and to minimize any complications. In the first and second groups of the study, there was a decrease in the pain on the VAS from 8.0 cm to 2.0 cm (p&lt;0.0001) and from 7.0 cm to 2,7 cm (p&lt;0.001) before and after the procedure, respectively. In the first and second groups of the study, there was an improvement in the indicator of functional status according to the KS from 70% (95% сonfidence interval (CI) 60‒90%) to 90% (95% CI 70‒100%, p&lt;0.0001) and from 70% (95% CI 70‒90%) to 90% (95% CI 80‒100%, p=0.001) before and after the procedure, respectively.

Differences of Dyspareunia in Primipara with 2nd Degree Perineal Laceration Sutured with Rapide Polyglactin 910 and Chromic Catgut Threads

BACKGROUND: Dyspareunia is persistent or recurrent pain during sexual intercourse. Perineal laceration, spontaneous or episiotomy, is one of the most common causes. Perineal lacerations that occur must be treated through suturing. Chromic catgut is a natural thread that is often used in medical practice, but this thread have a higher inflammatory response compared to Rapide Polyglactin 910. AIMS: To analyze the difference in the incidence of dyspareunia in primipara with 2nd degree perineal lacerations sutured with Rapide Polyglactin 910 and Chromic catgut threads METHOD: True experimental research with randomized controlled trial-single blinded method. The research was conducted at dr. Kariadi Semarang, RA Kartini Hospital and dr. Soeselo from August 2022 to February 2023. The research subjects were primipara with 2nd degree perineal lacerations which were divided into 2 groups, namely 45 subjects in the Chromic catgut group and 45 subjects in the Rapide Polyglactin 910 group. Evaluation of dyspareunia after 3 months was carried out using the Female Sexual Function Index (FSFI) RESULT:  Subjects sutured using Chromic catgut had a 2.7 times greater risk of experiencing dyspareunia when compared to using Rapide Polyglactin 910 (OR=2.7; 95% CI=1.1-6.6). A significant confounding factor was found, namely the act of episiotomy (p=0.047; OR=9.56; 95% CI=1.86 - 48.97). After controlling for these variables, the subjects who were sewn using Chromic had a significant risk (p=0.002, OR=5.39; 95% CI=1.76-16.50) CONCLUSION: Subjects with Chromic catgut have a higher risk of experiencing dyspareunia than using Rapide Polyglactin 910 threads after 3 months of suturing.
