Penerapan Metode Bayes untuk Mendiagnosa Penyakit Saraf Kejepit

A pinched nerve is a condition where certain nerves are compressed by tissues around the body, such as bones, cartilage and muscles. This causes the nerve to become damaged with symptoms of severe pain, tingling, and numbness during activity. Nerve pain can spread throughout the body. For example, patients with radiculopathy type spinal cord disease make the patient numb, and the nerve pain can spread to the feet and hands. Sylvani General Hospital also provides expert doctors who treat various diseases, including pinched nerve disease suffered by patients. However, there are several problems that often occur to patients when going for direct consultation due to time constraints, long queues, long waits, long distances to the hospital, and lack of costs. Because agencies need to have a system that can manage existing symptom data on pinched nerve disease and make it an online expert substitute information by utilizing technological developments to get maximum diagnostic results, and patients can find out the initial symptoms of one of them numbness, leg pain, arm pain, back pain, muscle weakness in the type of pinched nerve disease, namely radiculopathy, carpal tunnel syndrome, pinched nerves in the waist, piriformis syndrome, radial tunnel syndrome and treatment first by consulting through a system that has been created using the Bayes method. From the calculation process using the Bayes method above, it is known that the diagnosis of pinched nerve disease is diagnosed with nerve root syndrome (Radiculopathy) (P01) with a percentage of 72.55%.

ПОПЕРЕКОВА ДИСКЕКТОМІЯ З ДЕКОМПРЕСІЄЮ КАНАЛУ ЗА СИСТЕМОЮ DESTANDAU ENDOSPINE

Lumbar disc herniation is a common disease. There is severe pain in the buttock and leg, which may persist for more than 6 weeks even after conservative treatment. Currently, there are several surgical techniques for the treatment of lumbar disc herniation, ranging from laminectomy to microdiscectomy. The main advantages of endoscopic discectomy include: cosmetic appeal, minimally invasive nature, better visualization, shorter hospital stay and faster recovery. Objective. This article reviews discusses the management of patients with degenerative diseases of the lumbar spine by Destandau Endospine system. The authors shares his experience of the surgical technique and the results of percutaneous endoscopic discectomy using the Destandau system during the treatment of 51 patients with herniated disc and canal stenosis in the lumbar spine. The main advantages of the Destandau endoscopic system are a small skin incision and minimal damage to soft tissues. This is a minimally invasive intervention, which is applied through a skin incision 1.5–2 cm long. In order to ensure the accuracy and safety of the patient both before and during the operation, fluoroscopy is used. Under the control of an endoscope, the herniated intervertebral disc, free fragments of the disc are removed and the pinched nerve is released. Thus, rapid recovery is achieved during postoperative rehabilitation. Conclusions. The endoscopic system can be used to treat all types of intervertebral disc herniations and associated canal stenosis. It is a relatively safe procedure, provided proper preoperative planning and an experienced team of doctors. Most lumbar pathologies that are not related to instability can be successfully resolved with its help. The two main advantages of the Destandau endospinal system include minimally invasive surgery with minimal iatrogenic damage and excellent efficacy. In the case of its successful application, the recovery process is significantly shortened, without any restrictions for returning to everyday life.

Introduction: racism doesn’t care about democracy either

ABSTRACT As the US approaches an intense inflection point in this grand experiment with democratic ideals, a pinched nerve in the form of a presidential election, this second special anniversary forum considers what resources (I almost said weapons) lay undiscovered or undervalued with which we may forge a future. Fortunately, there are gems – brilliant in the proper light – available for use; from the Global South to the US South, this forum imagines more than geographic places, but rather forms of care and powerful Black feminist community-building and critique of the retrenchment of multiple forms of racialized domination.

The science of pinched nerves is a very important topic, especially for the general public and parents. However, it should be noted that teenagers can also experience this condition. A pinched nerve occurs when a nerve is compressed by surrounding tissues or structures, which can lead to symptoms such as pain, numbness and paralysis. This article discusses the mechanism by which pinched nerves occur, highlights the risk factors that play a role, and reviews diagnostic and treatment methods. In this context, further research into the prevention and treatment of pinched nerves is crucial to improve the quality of life of patients and reduce their impact on human health. Researchers focused on community outreach as a strategy to disseminate information and knowledge about pinched nerves. This counseling aims to provide the community with a deeper understanding of the symptoms, risk factors, and preventive measures that can be taken. Through this research, it is hoped that a more effective solution can be found in the prevention and treatment of pinched nerves, so as to reduce the incidence of cases and increase public understanding of the importance of maintaining nerve health. Thus, this article makes a positive contribution to disease prevention efforts and improving the overall welfare of the community.

Effect of Siravedha in the Management of Viswachi with special reference to Cervical Radiculopathy

Radiculopathy, commonly referred as pinched nerve, refers to a set of conditions in which one or more nerves are affected and their functioning is hampered. Cervical radiculopathy is a clinical condition resulting from compression of nerve roots due to disc herniation or degenerative stenosis which leads to neck pain, numbness and radiating arm pain in the distribution of the affected nerve root. Often this radicular pain is accompanied by motor or sensory disturbances also. The main treatments available are use of non-steroidal anti-inflammatory drugs, epidural steroid injection and surgery in the last stages. But the side effects of NSAID’s, incomplete neurologic recovery, loss of full cervical range of movement and surgical complications are the main hurdle in the management of cervical radiculopathy. In Ayurvedic classics, clinical picture of cervical radiculopathy can be explained under the heading of Viswachi. It is a Vatavyadhi mainly affecting the Kandaras leading to restricted movements and loss of function of upper limb. At present, there is no specific treatment procedure, which can offer quick relief of pain and other associated symptoms of cervical radiculopathy. Acharya Susruta mentioned Siravedha in the management of Viswachi. It is one of the most effective methods of Rakthamoksha by which vitiated Doshas can be eliminated in a faster way. In the present study, 150ml of blood was withdrawn from corresponding cephalic vein as a onetime procedure. Assessments were done before procedure, immediately after procedure, on 7th, 14th, 21st and 28th day after procedure. The results showed Siravedha is an effective treatment procedure in the management of Viswachi.

Complaints of Low Back Pain in Tailors

Low back pain (LBP) is one of the musculoskeletal disorders as a result of incorrect ergonomics. The impact caused by low back pain is bad posture, stiffness, pinched nerve, and muscle weakness. This study aims to determine the relationship between ages, years of service, length of sitting, work posture, and the chair’s ergonomics with complaints of low back pain in tailors at Pasar Petisah, Kota Medan, with 35 workers based on inclusion and exclusion criteria. The research tools are interviews, observations, and filling out questionnaires. This sampling technique is used purposive sampling methods. Data were analyzed using the STATCAL application with a 5% chi-square test. Based on the result, we concluded that there is a long relationship between ages (p=0,02), years of service (p=0,04), length of sitting (p=0,01), and work posture (p=0,03) with the occurrence of low back pain tailors. Tailors in the Petisah Market in Medan City are at risk for complaints of low back pain based on age, long years of service, a risky length of sitting, and a risky work posture. If the workers ignore low back pain, the impact is the emergence of serious problems such as stiffness in the spine, fractures, pinched nerves, and can even cause death.

Prevalence of Cervical Radiculopathy among Information Technology Professionals with Neck Pain

Background: Cervical radiculopathy, commonly called a “pinched nerve,” occurs when a nerve in the neck is irritated or compressed where it branches away from the spinal cord concerning particular neurologic and musculoskeletal conditions in the neck and upper limbs. Fifty-nine percent of work-related musculoskeletal disorders are reported annually by information technology (IT) professionals, among which 30% are neck pain-related disorders. Thus, this study aims to know the prevalence of cervical radiculopathy among IT professionals with neck pain. Aims: The aim of this study was to find out the prevalence of cervical radiculopathy among IT professionals with neck pain. Objectives: The objective of this study was to establish the relationship between cervical radiculopathy and neck pain and to find out the percentage of disability by using the Neck Disability Index (NDI). Materials and Methods: The prevalence study was carried out with a sample size (n = 92) involving IT professionals in Bangalore. The NDI questionnaire (NDI) related to daily life activities was used. To identify cervical radiculopathy, specialized testing was performed. Results: Out of 92 samples, 46 tested positive for cervical radiculopathy, showing a prevalence of 50%. Cervical radiculopathy was more prevalent among males than females. There was a difference (P < 0.05) in neck disability according to a special test. Conclusion: This study provides evidence for the prevalence of cervical radiculopathy among IT professionals with neck pain with a positive correlation with gender and working hours per day.

Changes in dorsal root ganglion CGRP expression in mouse pinch nerve injury model: Modulation by Somatostatin type-2 receptor

IntroductionOur previous work has shown that somatostatin effectively inhibits neuropathic pain by activating its type 2 receptor (SSTR2) in the dorsal root ganglion (DRG) and spinal cord of mice. However, the underlying mechanism of this activation has not been elucidated. MethodsTo explore further mechanisms, we examined pain behavior and the expression of neuropeptides such as calcitonin gene-related peptide (CGRP) in dorsal root ganglion neurons(DRGs) as well as the changes of the number of CGRP-IR DRGs in the mouse model of sciatic pinch nerve injury. ResultsIn this model, the number of medium and small DRG neurons in ipsilateral CGRP-IR was slightly increased, but not significantly, compared with sham animals at 3, 7, and 9 days after pinch nerve injury. This correlated with the behavioral readouts of hypersensitivity at the same time points. However, the magnitude of the painful behavior (Autotomy) was observed after application of SSTR2 antagonist (CYN154806, 5 mg/kg) in the injured nerve groups compared to the saline-treated injured group as well as the sham-operated group. Following pinch nerve injury, there was a significant decrease in the number of ipsilateral CGRP-IR small and medium DRG neurons in SSTR2 antagonist (anti-SSTR2)- but not saline-treated mice. These data also correlated with painful behavioral readouts where hypersensitivity was significantly increased by anti-SSTR2 but not saline treatment. Discussion/conclusionIn all, application of the SSTR2 antagonist to the pinched sciatic nerve suppressed CGRP expression and aggravated painful behavior, suggesting that CGRP expression in DRG neurons can be an important component of the pain mechanism and an indicator of pain behavior.

AYURVEDIC MANAGEMENT OF CERVICAL RADICULOPATHY: A CASE REPORT

Background: Cervical radiculopathy, commonly called a pinched nerve, occurs when a nerve in the neck is compressed or irritated where it branches away from the spinal cord and causes pain that radiates into the shoulder and/or arm, as well as cause muscle weakness and numbness. However, the pain or other symptoms often radiate to the parts of the body served by that nerve. The management available in the current mainstream is not satisfactory. We present a case of cervical radiculopathy, which was treated with the combination of ayurvedic panchakarma procedures and a combination of medications internally. Rationale of the case report: A 37- year- old female patient presented with neck stiffness, neck pain, and numbness at right hand and fingers for five years. Intervention: Ayurvedic procedures such as dhanyamla kizhi, dhanyamla dhara, marsha nasyam, along with internal ayurvedic medications, were carried out for 14 days, and surgery was prorogued as the patient responded positively. Result and outcome: There was a marked improvement in pain, stiffness, and range of movements of the neck. The outcome of this case report shows that cervical radiculopathy may be successfully managed with internal ayurvedic medicines along with panchakarma procedures.

Extra Burden on Urology Outdoor Due to Non Urology Flank Pain

Background: Flank pain is one of common urological emergency. It can be result of various causes. Most commonly results from one of three causes: urinary tract infection (UTI), kidney stones, and musculoskeletal problems like a muscle strain or pinched nerve. Objective: Determine frequency of none urological flank pain burden in urology outdoors. Methods: This was prospective descriptive case study conducted at department of urology and transplantation at Jinnah Postgraduate Medical Center Karachi from September 2020 to December 2020. All patients with flank pain, who visited in urology outdoor, were included in study. All patients had detailed history and physical examination. Urinalysis and ultrasound abdomen were done in all patients. CT KUB was also done in patients who had abnormal ultrasound finding of kidney ureter and bladder. Results: Total 100 patients were included in this study, 41 (41%) male while 59 (59%) patients were females. 45 patients had right sided pain, 34 had left sided while remaining 21 patients had bilateral flank pain and six patients had also lower urinary tract symptoms along with pain. 13 patients had positive renal punch on examination, 23 patients had positive straight leg rising sign and rest of the 64 patients’ examination was unremarkable. 55 patients had urology related pathology on ultrasound, in 9 patients had non urological pathology and rest 36 patients it was unremarkable. CT KUB was done in all 55 patients who had positive findings on ultrasound showing pathology in kidney and ureter in which 47 patients CT scan had confirmed the diagnosis while in 8 patients it was in remarkable. Conclusion: flank pain is not always secondary to renal origin. It has wide spectrum of alternative significant causes also. Keywords: Flank pain, none urological, CT KUB

Somatostatin Type 2 Receptor Antibody Enhances Mechanical Hyperalgesia in the Dorsal Root Ganglion Neurons after Sciatic Nerve-pinch Injury: Evidence of Behavioral Studies and Bax Protein Expression.

Our previous study has indicated that somatostatin potently inhibits neuropathic pain through the activation of its type 2 receptor (SSTR2) in mouse dorsal root ganglion and spinal cord. However, the underlying mechanism of this activation has not been elucidated clearly. The aim of this study is to perform the pharmacological studies on the basis of sciatic nerve-pinch mice model and explore the underlying mechanism involving SSTR2. On the basis of a sciatic nerve-pinch injury model, we aimed at comparing the painful behavior and dorsal root ganglion neurons neurochemical changes after the SSTR2 antibody (anti- SSTR2;5μl,1μg/ml) administration in the mouse. After pinch nerve injury, we found that the mechanical hyperalgesia and severely painful behavior (autotomy) were detected after the application of SSTR2 antibody (anti-SSTR2; 5μl, 1μg/ml) on the pinch-injured nerve. The up-regulated phosphorylated ERK (p-ERK) expression and the apoptotic marker (i.e., Bax) were significantly decreased in DRGs after anti-SSTR2 treatment. The current data suggested that inhibitory changes in proteins from the apoptotic pathway in anti-SSTR2-treated groups might be taking place to overcome the protein deficits caused by SSTR2 antibody and supported the new therapeutic intervention with SSTR2 antagonist for neuronal degeneration following nerve injury.

The effectiveness of shoe modifications and orthotics in the conservative treatment of Civinini-Morton syndrome: state of art.

Civinini Morton’s Syndrome (CMS), better known as Morton’s Neuroma, is a benign enlargement that typically affects the third common digital branch of the plantar nerve. It is a common cause of metatarsalgia leading to debilitating pain. It prefers the female gender, with a female to male ratio of 5:1 and an average age of 50 years at time of surgery. Precise aetiology remains under debate, with four etiopathogenetic theories often cited in the literature. Clinical symptoms, physical exam and instrumental evidence are important in assessing and grading the disease. Biomechanics seem to play an important role, especially regarding the usefulness of correct footwear. The first approach in the early stages of this condition usually begins with shoe modifications and orthotics, designed to limit the nerve compression. In order to prevent or delay the development of CMS, shoes should be sufficiently long, comfortable, broad toe-boxed, should bear a flat heel and a sufficiently thick external sole which should not be excessively flexible. Most authors suggested that an insole with medial arch support and a retrocapital bar or pad, just proximal to the metatarsal heads, displaces the pressure sites and can be beneficial to relieve the pain from the pinched nerve. A threshold period of 4.5 months appears to emerge from the results of the analysed studies, indicating that, beyond this period and in neuromas larger than 5-6 mm, orthotics and/or shoes modifications do not seem to give convincing results, proving to be more a palliation for the clinical condition to allow an acceptable life with pain rather than a real treatment.

Novel technique of diagnosing and reducing pain in cervical radiculopathy

Background: Neck pain with upper limb pain is a common complaint of patients seen in Out Patient Department (OPD). Such pain may be because of a pinched nerve. There is inflammation in the nerve which causes radicular symptoms. The available clinical tests for cervical radiculopathy are provocative tests, difficult to perform and techniques vary from author to author. The reliability of these tests is only when done in clusters. We devised a novel non-provocative clinical sign to diagnose cervical radiculopathy and a method to reduce upper limb radicular pain and thereby improving the function of the upper limb. Method: Patient’s bilateral pronated wrists were palpated dorsomedially on the ulnar styloid. This elicited tenderness over the Dorsal Cutaneous branch of Ulnar Nerve (DCU). The painless active degree of movement at shoulder and elbow joints was noted. Nerve block at the palpated tender point was given using 2% lignocaine in 95 patients. We used Visual Analogue Scale score to measure radicular pain intensity before and 5 minutes after injection Results: All patients had tenderness at the DCU on the symptomatic upper limb. All patients had reduction in VAS of radicular pain from 7.36±0.89 before injection to 1.89±0.98 after injection with improvement of shoulder and elbow active movement.Conclusion: We recommend palpation of DCU in both upper limbs in all cases of suspected cervical radiculopathy. Palpation to elicit tenderness over DCU in cervical radiculopathy, was documented as Pote’s sign positive. Injection of local anesthetic agent over DCU reduces pain and improves upper limb function and it was documented as Pote’s test positive. This test is of diagnostic and therapeutic significance. This test is minimally invasive and can be done in an OPD set-up.

Cervical Radiculopathy Alleviating by Manipulative Correction of Cervical Hypolordosis

The purpose of this report is to present an interesting case of cervical radiculopathy in a patient with a prominent cervical hypolordosis treated by chiropractic adjustment. A 55-year-old office worker with severe neck pain and numbness of the right arm sought chiropractic treatment. Following 12 sessions of cervical adjustment, the patient experienced complete alleviation from radiculopathy and full restoration of cervical curvature. Neck pain is common and the cause is usually multifactorial. About 88% of uncomplicated neck pain is self-limiting. Conservative treatment is advocated as initial modality for most patients. Cervical radiculopathy, however, is a potential problem because nerve impingement can cause disability due to numbness or paresthesia, and even weakness, requiring surgical intervention. The best chance for sensorimotor recovery is with prompt intervention to decompress the pinched nerve. Instead of watchful waiting, early application of chiropractic adjustment may help release nerve impingement, and avoid medications and operations in patients with neglected nerve compression.

Ayurvedic management of cervical spondylosis radiculopathy

Radiculopathy, commonly referred as pinched nerve, refers to a set of conditions in which one or more nerves are affected and their functioning is hampered. This phenomenon is termed as neuropathy. This can result in pain or more precisely in radicular pain. In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. The management available in the current era of medicine is not satisfactory. Here, we are presenting a case of cervical spondylosis (CS) radiculopathy which was treated with a combination of Panchkarma procedures and Ayurvedic oral drugs. Greeva stambh was considered as the Ayurvedic diagnosis for the case. The treatment protocol designed for the particular case was Panchatikta ksheera Basti (enema with medicated milk) for 16 days along with Shalishastic pind sweda. The oral medication prescribed was Ashwagandha churna (Withania somnifera Dunal), Shatavari churna (Asparagus recemosus Wild), Gokshur churna (Tribulus terrestris L.) each in a dose of 2 g, Sarpgandha churna (Rauvolfia serpentina (L) Benth. Ex Kurz) 1 grms, Shankha bhasma 500 mg with Luke warm water, Yograj guggulu-3 tablet with Dashmool kwath in a dose of 40 ml, Ashwagandha avaleha 10 g with lukewarm water. All these drugs were prescribed for twice a day. Visual analog scale and range of motion were the parameter used to assess patient and considerable improvement was noticed in the case after a month of treatment which sustained in follow-up duration of 2 months. The case study demonstrate that CS radiculopathy may be successfully managed with Ayurvedic treatment.

Retractor endoscopic techniques in the treatment of entrapment peripheral neuropathies

With increasing awareness for minimally invasive approaches, endoscopic techniques for peripheral nerve decompression are becoming increasingly popular. The first endoscopic approach to release a pinched nerve was for carpal tunnel release through a single entry port, whereby the compressed canal was dilated with bougies and an endoscope introduced into this canal to transect the transverse carpal ligament. Since most of the manipulations with the blunt bougie in this technique were done in a blind fashion, there was a lurking potential for iatrogenic nerve injury using the bougie technique. Thus the retractor-integrated endoscopic technique was developed. In this technique, the retractor bearing the endoscope is introduced into a plane above the compressing ligaments and the nerve proper and a bird’s eye perspective of the anatomical site is gained. Owing to the simplicity of the technique, the retractor-endoscope was used to decompress any nerve at any site in the body: furthermore it was employed for harvesting nerves, vessels and tendons for transplantation. In this paper, we describe the various endoscopic techniques used for decompression in peripheral nerve entrapment syndromes and provide a comprehensive and comparative metaanalysis of the techniques.

Nuclear factor erythroid 2-related factor 2 antibody attenuates thermal hyperalgesia in the dorsal root ganglion: Neurochemical changes and behavioral studies after sciatic nerve-pinch injury

Oxidative stress is generated in several peripheral nerve injury models.Nuclear factor erythroid 2-related factor 2 (Nrf2) is activated to have a role in antioxidant effect. After nerve injury, the severely painful behavior is also performed. However, little has been explored regarding the function of Nrf2 in this painful process. Therefore, in this study, we compared the effects of Nrf2 antibody administration following sciatic nerve-pinch injury on painful behavior induced in young mice and neurochemical changes in dorsal root ganglion neurons. After pinch nerve injury, we found that the magnitude of the thermal allodynia was significantly decreased after application of Nrf2 antibody (5ul, 1mg/ml) in such injured animals and phosphorylated ERK(p-ERK) as well as the apoptotic protein (i.e., Bcl-6) in DRG neurons were also down-regulated in the anti-Nrf2-treated injured groups compared to the saline-treated groups. Taken collectively, these data suggested that the Nrf2 antibody reduced thermal hyperalgesia via ERK pathway and the down regulation of Bcl-6 protein from the apoptosis pathway might be protecting against the protein deletions caused by anti-Nrf2 effect and suggested the new therapeutic strategy with Nrf2 inhibitor following nerve injury.

Primary Infraorbital Foramen Decompression for the Zygomaticomaxillary Complex Fracture: Is It Essential?

The frequency of zygomaticomaxillary fracture is second only to nasal bone fracture. Up to 30% to 80% of zygomaticomaxillary fracture patients complain of sensory disturbance results from infraorbital nerve injury. The objective of this study was to detect what factors are related to infraorbital nerve recovery and specifically to investigate decompression of infraorbital foramen improves sensory recovery. A total of 257 patients were assessed with unilateral zygomaticomaxillary complex fracture, treated with open reduction and internal fixation with orbital floor reconstruction. Of these, 166 patients followed up over 6 months were included in this study. The data collected included age, sex, pre, and postoperative sensory score measured by visual analogue scale (range: 0-10). Sensory score was measured at the infraorbital nerve innervation. The impact of decompression operation on the change of sensory score was compared. Statistical analysis was performed using SPSS 18.0 software (SPSS Inc, Chicago, IL). In patients with preoperative hypoesthesia, difference between postoperative and preoperative sensory score was 3.2 (decompression group), 4.4 (nondecompression group), respectively, but not significant (P > 0.05). In patients without preoperative hypoesthesia, difference between postoperative and preoperative sensory score was -0.2 (decompression group), -0.3 (nondecompression group), respectively, and did not show significant association (P > 0.05). Based on this result, in patients with preoperative hypoesthesia, infraorbital decompression operation is not useful for sensory recovery. This result indicates infraorbital sensory disturbance occurs from not only pinched nerve injury at the infraorbital foramen but also traction nerve injury at the other part of the nerve.
