Local anesthetics (LAs) are an important alternative for postoperative analgesia; however, the short duration of LAs limits their use. Thus, we previously developed LL-1, a mixture of QX-OH and levobupivacaine (LB) that produces regional anesthesia for more than 10 h in rats. The aim of this study is to investigate the long-acting mechanism of LL-1 in vivo and in vitro.

Anti-gravity treadmill training is a therapeutic option to help recovering runners return to activity after injury. This current concept paper provides a synopsis of the latest evidence of the biomechanical and metabolic changes that occur with body weight support (BWS) treadmill training, effects of antigravity treadmill training on clinical outcomes and clinical case studies in injured runners. Literature searches identified studies with descriptive, experimental and interventional designs and case studies that examined acute and chronic use of antigravity treadmills in runners and relevant populations. Laboratory-based studies were included to provide technical considerations for rehabilitation programming. Antigravity treadmills use causes reductions in cadence, ground reaction forces (GRF), GRF impulses, knee and ankle range of motion, and vertical stiffness, with elevations in stride duration, flight time, ground contact time, and plantarflexion. Antigravity treadmills appear useful across a spectrum of injuries in runners, including postsurgical repair of osteochondral defect, stress reactions (medial tibia, pelvis), and lumbar disc herniation. Runners may preserve aerobic fitness, muscle activation patterns, and muscle mass during recovery compared to traditional rehabilitation protocols. Technical considerations for accurate loading include treadmill frame adjustment to appropriate height to ensure accuracy of level of BWS while running, and monitoring for fast cadence to ensure impact loading rates remain low. Speed or grade can be increased to maintain metabolic demand and fitness while minimizing bone and tissue loading. Monitoring for symptom provocation will guide protocol adjustments to BWS and prescriptions. Once able to run pain-free (sustained or interval) >95% BWS for >30 min, the runner is likely ready to safely transition to ground running. Antigravity treadmill training can be considered when available to facilitate smooth transition back to ground running in a conditioned state.

Fibromuscular dysplasia (FMD) can cause cerebral aneurysms and dissection, which can lead to stroke. Angiographic findings are important in the diagnosis. We report a case of FMD in which the cause of hemorrhage could not be determined by angiography.

Intussusception is a common condition of bowel obstruction in pediatric patients. However, 5% of all cases occur in adults, mostly aged over fifty, with no difference based on sex, representing about 1% of all causes of bowel obstruction. Compared to pediatric population, it is triggered by a pathologic lead point in about 85% of cases, represented in 60% of cases by malignant and benign neoplasms. Among these neoplasms, an inflammatory fibroid polyp (IFP), a benign neoplastic submucosal lesion also known as Vanek's tumor, is considered a very uncommon cause of adult intussusception. Clinical presentation could differ by location and size of tumor, and may include abdominal pain, nausea, vomiting, diarrhea or constipation, bleeding, weight loss, palpable abdominal mass, bowel obstruction, and gastrointestinal bleeding. Considering its common and non-specific symptoms, radiologic imaging plays a key role in the diagnosis of an IFP, especially computed tomography (CT) scan, which represents the most sensitive modality to confirm intussusception. However, bowel sonography (BS) has become an accurate procedure in various pathological intestinal diseases, also including intussusception. In this paper, we report a rare case of ileo-ileal intussusception secondary to Vanek's tumor diagnosed by BS.

Lupus anticoagulant (LA), an antiphospholipid antibody, prolongs activated partial thromboplastin time (APTT) despite the presence of a hypercoagulable state . Irrespective of whether they receive antithrombotic therapy, meticulous anesthetic management is imperative in patients with LA positivity to prevent thrombotic complication. Additionally, emergency surgery in such patients can be challenging, as the time to devise perioperative strategies is limited. Here, we described the case of a patient with LA positivity and prolonged APTT who underwent emergency laparoscopic cholecystectomy with successful anesthetic management using epidural analgesia. An 83-year-old woman presented with acute cholecystitis and underwent emergency laparoscopic cholecystectomy. Preoperative blood test results revealed a prolonged APTT of 83 s, prothrombin time/international normalized ratio of 1.14, and normal platelet count. The patient had experienced a marked prolongation of APTT ten years previously, which was attributed to LA positivity, and she had previously undergone surgery for rectal cancer under general and epidural anesthesia. The patient did not receive antithrombotic therapy, and she demonstrated neither liver dysfunction nor a bleeding tendency. We prioritized optimal analgesia to enable early mobilization; therefore, an epidural catheter was placed in preparation for transition to open abdominal surgery. The operation was completed under laparoscopy, and good pain control was achieved postoperatively with continuous epidural analgesia, facilitating early ambulation. The epidural catheter was removed on the second postoperative day, and the patient did not develop any signs of thromboembolism or neurologic complications during her hospital stay. Anesthetic management for emergency laparoscopic cholecystectomy was successfully performed using epidural analgesia in a patient with LA positivity and prolonged APTT. Careful evaluation of laboratory data, treatment history, and clinical symptoms is of critical importance in such patients.

Pruritus is the sensation of itching; it can be caused by dermatologic and systemic conditions. An exposure history may reveal symptom triggers. A thorough skin examination, including visualization of the finger webs, anogenital region, nails, and scalp, is essential. Primary skin lesions indicate diseased skin, and secondary lesions are reactive and result from skin manipulation, such as scratching. An initial evaluation for systemic causes may include a complete blood count with differential, creatinine and blood urea nitrogen levels, liver function tests, iron studies, fasting glucose or A1C level, and a thyroid-stimulating hormone test. Additional testing, including erythrocyte sedimentation rate, HIV screening, hepatitis serologies, and chest radiography, may also be appropriate based on the history and physical examination. In the absence of primary skin lesions, physicians should consider evaluation for malignancy in older patients with chronic generalized pruritus. General management includes trigger avoidance, liberal emollient use, limiting water exposure, and administration of oral antihistamines and topical corticosteroids. If the evaluation for multiple etiologies of pruritus is ambiguous, clinicians may consider psychogenic etiologies and consultation with a specialist.

Complex Regional Pain Syndrome (CRPS) is a chronic, disabling condition with prolonged or excessive pain persisting in a limb usually following a triggering injury or trauma to an extremity. The subjective expression of pain is disproportionate to what would be objectively expected from the initial injury. It may also be accompanied by a variety of autonomic disturbances and trophic abnormalities such as swelling in the affected area and changes in skin color and temperature. Understanding the pathophysiology of CRPS remains a medical challenge, along with making the diagnosis and devising an effective treatment plan. There are limited randomized controlled trials and definitive treatment is yet to evolve for this life-altering condition. This case study illustrates the safe, cost-effective addition and efficacious use of hypnosis in the integrative treatment plan for a teenager with CRPS.

Epidural injections have been used for many years in the treatment of chronic pain in patients with chronic backleg pain and chronic neck-arm pain. We aimed to compare the efficacy of lumbar and cervical epidural steroid injections on pain palliation, duration of pain relief and patient satisfaction.

Current therapies are quite unsuccessful in the management of neuropathic pain. Therefore, considering the inhibitory characteristics of GABA mediators, the present systematic review and meta-analysis aimed to determine the efficacy of GABAergic neural precursor cells on neuropathic pain management.

Vestibular migraine (VM) presents mainly with recurrent vestibular symptoms and migraine. A great number of patients with VM have cochlea symptoms such as tinnitus, hearing loss.
