This study aims to compare the reduction in knee pain between ultrasound-guided cryoneurolysis and bipolar radiofrequency ablation (RFA), as measured by the Numerical Rating Scale (NRS) at predefined follow-up intervals.

Therapeutic options for SIJ pain include intra-articular corticosteroid injections, which provide symptomatic relief but typically require repeated administration due to variable and short-lived efficacy. More recently, pulsed radiofrequency (PRF) has been investigated for joint pain management through intra-articular electrode placement and stimulation. However, its effectiveness in treating SIJ pain remains insufficiently studied and warrants further exploration.

The researchers are working to improve recovery after heart surgery by reducing reliance on opioids. Newer regional anesthesia techniques can provide strong pain relief with fewer risks, but the choice of method depends on each patient's condition, medications, and surgical plan

Postoperative pain management is considered an integral part of perioperative care in patients undergoing thoracotomy. In order to reduce these complications, multiple regional techniques have been developed for thoracotomy including Intercostal nerve block, Erectospinae plane block and serratus block. Multiple adjuvants have been used in regional analgesia including adrenaline,clonidine,magnesium sulphate,dexmedatomidine and opoids.

The aim of this study is to compare the effectiveness of super-voltage pulsed radiofrequency of stellate ganglion and super-voltage pulsed radiofrequency of T2-T3 sympathetic ganglia in the treatment of postmastectomy pain syndrome.

Breast cancer remains the most frequently diagnosed cancer and a major cause of cancer-related mortality among women worldwide. Modified radical mastectomy (MRM), a common surgical procedure for breast cancer, is associated with significant postoperative pain, which may delay recovery and contribute to the development of chronic postmastectomy pain syndrome (PMPS). To address this, regional anesthesia techniques have been increasingly incorporated into multimodal analgesia strategies to reduce opioid consumption and enhance patient outcomes. Interfascial plane blocks, in particular, offer safe and effective analgesia under ultrasound guidance. The erector spinae plane block (ESPB), first described in 2016, involves injection of local anesthetic deep to the erector spinae muscle and may spread to the paravertebral space, providing both somatic and visceral analgesia. A bilevel approach may enhance dermatomal coverage. Meanwhile, the pectoserratus plane block (PSPB), which combines PECS II and serratus anterior blocks, targets nerves of the anterior and lateral chest wall and has shown efficacy in breast surgery

Breast cancer is the second most common cancer world-wide following lung cancer. It afflicts about 1.7 million patients annually, of which 60% mandate surgery of the breast and/or the axilla, and nearly 20-50% of them may develop post mastectomy pain syndrome . After breast cancer surgery, between 6% and 86% of people may develop tight bands of fibrous tissue under their skin, known as axillary web syndrome. These bands can cause pain in the shoulder area by trying to raise or extend the arm. Shoulder pain is a common side effect of breast cancer surgery and treatment. Various medical and interventional procedures have been tried for treating postmastectomy shoulder pain, with varying efficacy . Among the interventional procedures that may have a role for treatment. Innervation of the glenohumeral joint (GHJ) can be divided into anterior and posterior innervation from articular branches of the suprascapular nerve (SN):C5 \&6 (posterior-lateral), axillary nerve (AN):C5 \&6 (anterior-lateral, inferior, and posteriorlateral), and lateral pectoral nerve (LPN): C5 \&6 (anterior superior)

The goal of this clinical trial is to learn if drugs as cyclophosphamide (C) and etoposide (E) work to treat advanced head and neck cancer in adults. It will also learn about the safety of both drugs. The main questions it aims to answer are: Do drugs C and E work to treat advanced head and neck cancer, after failure on first line chemotherapy? What medical problems do participants have when taking drugs C and E? Researchers will compare drugs C and E in combination to a placebo (a look-alike substance that contains no drug) to see if these 2 drugs works to treat advanced head and neck cancer. Participants will: Take drug C every 3 weeks and drug E every 4 weeks or a placebo every week for 6 months. Visit the clinic once every 3 weeks for checkups and tests. Keep a diary of their symptoms.

This study aims to compare the frequency of occurrence of ipsilateral shoulder pain in patients undergoing thoracotomy with ultrasound-guided interscalene block, anterior suprascapular block as adjunct to epidural and epidural block only.

Acute post-mastectomy pain can cause adverse impacts on the patients as delayed discharge from post-operative recovery area, impairs pulmonary and immune functions, increases risk of ileus, thromboembolism, myocardial infarction and may lead to increased length of hospital stay. It is also an important factor leading to the development of chronic post mastectomy pain syndrome (PMPS) in almost half of the patients. Various regional anesthetic techniques have been described for postoperative pain relief after mastectomy, for example, thoracic epidural anesthesia, intercostal nerve block, paravertebral block, serratus anterior plane block, and pectoral nerve I and II blocks. All of them offer satisfactory pain relief after mastectomy. Erector spinae plane block is a novel para-spinal regional anesthesia technique, , promises to provide effective visceral as well as somatic analgesia after carcinoma of the breast surgeries. The ultrasound-guided rhomboid intercostal block sub-serratus plane block (RISS) is a novel analgesic technique The RISS block anesthetizes the lateral cutaneous branches of the thoracic intercostal nerves and can be used in multiple clinical settings for chest wall and upper abdominal analgesia

Management of acute post-operative pain has received keen attention in recent years with considerable concurrent advancement in the field. The importance of effective pain relief has long been realised, and acute pain services (APS) are operational in majority of the hospitals in the developed world for decades. Postoperative pain following abdominal surgery if severe enough may cause several side effects as "splinting, hypoventilation, atelectasis, immobility, hypercoagulability, thromboembolic events, vasoconstriction, tachycardia, increased systemic vascular resistance, dysrhythmias and cardiac ischemia in susceptible patients, insomnia, anxiety, feeling of helplessness". Ultrasound-guided fascial plane blocks have been rapidly incorporated into regional anaesthesia practice in recent years as an alternative to neuraxial techniques and involve injection into a tissue plane to provide analgesia in various anatomic areas. External oblique intercostal plane block (EOIPB) is a novel block, which has been described as an important modification of the fascial plane blocks that can consistently involve the upper lateral abdominal walls. The erector spinae plane (ESP) block is a new regional aesthetic technique that can be used to provide analgesia for a variety of surgical procedures or to manage acute or chronic pain. The technique is relatively easy to perform on patients. The ESPB involves injection of local anaesthetic in the erector spinae fascial plane, superficial to the tip of the transverse process of the vertebra and deep to the erector spinae muscle.

This study aims to compare the costotransverse foramen block with erector spinae plane block in modified radical mastectomy.

Pain accompanying Inguinal lymph node dissection triggers a complex stress response leading to impairment of pulmonary, immunological and metabolic function. Opioids are the current gold standard drug for postoperative pain relief, however exposure to large doses lead to multiple side effects of varying significance such as nausea, vomiting, dizziness, constipation, respiratory depression, hypoventilation and sleep disordered breathing. Therefore, strategies other than opioids are recommended without sacrificing proper and effective analgesia, especially in cancer patients who are more susceptible to tolerance and addiction. Transversalis Fascia Plane Block is used in patients undergoing various surgeries like iliac crest bone harvesting, appendicectomy, cecostomy and inguinal hernia repair, often in combination with TAP block. The initial description of TFPB was with patients in the supine position, with a linear array or curvilinear probe placed between the iliac crest and the costal margin. The external oblique, internal oblique and transversus abdominis muscles and the transversus aponeurosis are identified. The entry of the needle has to be in-plane, from the anterior aspect, and after traversing through the deep surface of the transversus abdominis muscle, local anesthetic is injected to separate the transversalis fascia from the transversus muscle. Studies have demonstrated that this intervention blocks the proximal branches of T12 and L1 and to a lesser extent T11 in the plane between the transversus abdominis muscle and the transversalis fascia. Since its initial description, ultrasound (US)-guided TFPB has been explored in many randomized controlled trials for patients undergoing iliac crest bone harvesting, lower segment caesarean section (LSCS), inguinal hernia repair and hip surgeries.

Breast cancer is considered the commonest malignancy affecting women with an incidence exceeding one million cases per year. Although it has a favorable prognosis with improved lines of treatment, some complications may still disturb the patient's life quality. One of these complications is post-mastectomy pain syndrome (PMPS) .Regional Anaesthesia (RA) is considered one of the most effective methods in reducing acute pain after breast surgeries, these include pectoral nerves block (PECS), serratus anterior plane block (SAPB), paravertebral plane block (PVPB) and erector spinae plane block (ESPB) . Our study is aiming for comparing the effect of preoperative PVPB versus preoperative ESPB in the prevention of PMPS in patients undergoing unilateral breast surgeries.
