Ribosome profiling reveals that post-transcriptional control of Nalf1 by heterogeneous nuclear ribonucleoprotein L is required for paclitaxel-induced neuropathic pain.

Sensory neurons are integral to the genesis and maintenance of neuropathic pain. The molecular mechanisms that mediate long-lived changes in their excitability are unclear. Here, we leverage functional genomics approaches to survey changes in RNA abundance and translation in dorsal root ganglion neurons from a mouse model of paclitaxel-induced neuropathic pain. We focus specifically on females as paclitaxel is a first-line therapy for breast cancer. The sequencing data indicate that substantially more changes occur at the level of translation (n = 404) than transcription and decay (n = 109). W

Proneurotrophin-3 contributes to chemotherapy-induced neuropathic pain through TrkC-mediated CCL2 elevation in DRG neurons.

Cancer patients undergoing treatment with antineoplastic drugs often experience chemotherapy-induced neuropathic pain (CINP), and therapeutic options for managing CINP are limited. Here, we show that systemic paclitaxel administration upregulates the expression of neurotrophin-3 (Nt3) mRNA and its encoded proneurotrophin-3 (proNT3) protein in the neurons of dorsal root ganglia (DRG), but not in the spinal cord. Blocking this upregulation attenuates paclitaxel-induced mechanical, heat, and cold nociceptive hypersensitivities and spontaneous pain without altering acute pain and locomotor activit

Chemotherapeutic drug elemene induces pain and anxiety-like behaviors by activating GABAergic neurons in the lateral septum of mice.

Most chemotherapeutic drugs are potent and have a very narrow range of dose safety and efficacy, most of which can cause many side effects. Chemotherapy-induced peripheral neuropathy (CIPN) is the most common and serious side effect of chemotherapy for cancer treatment. However, its mechanism of action is yet to be fully elucidated. In the present study, we found that the treatment of the chemotherapy drug elemene induced hyperalgesia accompanied by anxiety-like emotions in mice based on several pain behavioral assays, such as mechanical allodynia and thermal hyperalgesia tests. Second, immuno

Impacts of radiation therapy on quality of life and pain relief in patients with bone metastases.

Bone metastases (BM) are a common complication in advanced cancer patients, significantly contributing to morbidity and mortality due to their ability to cause pain, fractures, and spinal cord compression. Radiation therapy (RT) is vital in managing these complications by targeting metastatic lesions to ease pain, improve mobility, and reduce the risk of skeletal-related events such as fractures. Evidence supports the effectiveness of RT in pain relief, showing its ability to provide significant palliation and lessen the need for opioid painkillers, thereby enhancing the overall quality of lif

JWH-182: a safe and effective synthetic cannabinoid for chemotherapy-induced neuropathic pain in preclinical models.

Chemotherapy-induced neuropathic pain (CINP), a condition with unmet treatment needs, affects over half of cancer patients treated with chemotherapeutics. Researchers have recently focused on the endocannabinoid system because of its critical role in regulating our bodies' most important functions, including pain. We used in vitro and in vivo methods to determine the toxicity profile of a synthetic cannabinoid, JWH-182, and whether it could be potentially effective for CINP alleviation. In vitro, we evaluated JWH-182 general toxicity, measuring fibroblast viability treated with various concent

Pediatric neck pain of a 10-year-old child with cervical spinal tumor evaluated and managed in direct access physical therapy: a case report.

INTRODUCTION: Differential diagnosis of pediatric neck pain requires age-appropriate communication and assessment tools. Recognizing these age-related nuances is critical, emphasizing the role of physical therapists in assessing and managing pediatric patients while ruling out severe pathologies. CASE DESCRIPTION: A 10-year-old male presented to physical therapy with a five-week history of increasing neck pain. A thorough history and segmental cervical examination considering the patient's age and development, led to patient referral to the emergency department. This case underscores the sign

Paget Disease of Bone Harboring Bone Metastatic Neuroendocrine Cancer: A Case Report.

In this case report, we describe an uncommon case of neuroendocrine cancer of unknown origin began with cauda equina syndrome in a patient affected by Paget disease of bone (PDB). A 76-year-old man with diagnosis of PDB, without history of pain or bone deformity, developed sudden severe low back pain. Bone alkaline phosphatase was increased and MRI and whole-body scintigraphy confirmed the localization of the disease at the third vertebra of the lumbar spine. Treatment with Neridronic Acid was started, but after only 2 weeks of therapy anuria and bowel occlusion occurred together with lower li

[Two Cases of Neuroendocrine Carcinoma of Colon and Rectum].

We report 2 cases of neuroendocrine carcinoma(NEC)of colon and rectum with distant metastasis. The treatment of NEC with distant metastasis is based on the treatment of small cell lung cancer, but that is controversial because NEC is relatively rare. Case 1: A 75-year-old man who was admitted for anal pain. Physical examination showed the anal tumor and swelling inguinal lymph nodes. CT showed rectum tumor and multiple lymph node metastases to the pelvis and inguinal region. Colonoscopy showed a Type 3 tumor in the rectum. He was diagnosed with NEC based on biopsy and immunostaining. Colostomy

A Multicenter Clinical Study of Expected and Unexpected Side Reactions During and After Skin Cancer Treatment by Photodynamic Therapy.

Photodynamic therapy (PDT) has been widely used for oncologic indications, especially nonmelanoma skin cancer such as superficial and nodular basal cell carcinoma (BCC). We present a multicenter clinical study conducted between 2012 and 2014 analyzing the adverse reactions during and after PDT with a standardized protocol in 866 lesions. A total of 728 patients with positive clinical and histopathological diagnosis for BCC with up to 2 cm diameter were treated. The procedure consisted of curettage and topical application of cream containing 20% methyl 5-aminolevulinate. The illumination (630 n

A new technique for superior hypogastric plexus block: the posteromedian transdiscal approach.

Superior hypogastric plexus block has been advocated for the treatment of cancer related pelvic pain. Neurolysis is usually established using the classical posterolateral approach in the prone position, in which correct placement of the needle is sometimes difficult due to vertebral anatomy and the patient's inability to lie prone. We describe an alternative posteromedian transdiscal approach under fluoroscopic guidance for the treatment of intractable pelvic pain in three patients, in whom the classical approach was not possible. The L5-S1 interdiscal space was identified with fluoroscopy. Th

Efficacy of subcutaneous and topical local anaesthesia for pain relief after resection of malignant breast tumours.

OBJECTIVE: Infiltration and topical application of local anaesthetics close to the surgical wound may be used to prevent postoperative pain. We evaluated the efficacy of these treatments after breast surgery for cancer. DESIGN: Double-blind randomised trial with two treatment groups and one control group. SETTING: University hospital, Sweden. INTERVENTIONS: Patients were allocated to treatment with bupivacaine infiltration (n = 29), topical application of lignocaine/prilocaine (n = 31), or no local treatment (n = 30). MAIN OUTCOME MEASURES: Difference and time related patterns in pain scor

Comparison of patellar resurfacing versus nonresurfacing in total knee arthroplasty.

OBJECTIVES: To determine whether resurfacing the patellar component during total knee replacement (TKR) influences the clinical outcome. DESIGN: A retrospective study of data gathered prospectively during the recovery course of patients who underwent TKR with or without patellar resurfacing. SETTING: Victoria General Hospital, Halifax, NS. PATIENTS: One hundred and eighty-five patients operated on between 1992 and 1995. The inclusion criteria were (a) osteoarthritis, (b) replacement carried out by 2 independent surgeons, (c) no comorbid illness such as rheumatoid arthritis, cancer or infect

Chronic pelvic pain: presumptive diagnosis and therapy using GnRH agonists.

Chronic pelvic pain has a prevalence of 15% to 30% of reproductive-age women. It causes a sizable minority of all gynecological visits, and is responsible for much physical and psychological suffering. Although laparoscopic inspection, plus treatment, for pelvic pain has been considered ideal, it is often unnecessary, fruitless, and even hazardous, besides being expensive. Therefore, empirical medical therapy has much to recommend it. Foremost is the fact that endometriosis is the most frequent source of chronic pelvic pain, and responds well to medical treatment. In fact, GnRH analogs (agonis

Surgery for nonalcoholic chronic pancreatitis.

There are few reports on operations in patients with nonalcoholic pancreatitis. Between 1985 and 1995 we operated on 58 such patients, 38 of whom were male and 20 female with a mean age of 35 years (range 5-72 years). The indications for operation were pain (n = 49), biliary obstruction (n = 12), duodenal obstruction (n = 10), portal hypertension (n = 11), cysts (n = 14), and pancreatic ascites (n = 3). Thirty-four patients with a dilated pancreatic duct underwent pancreaticojejunostomy; cysts were drained internally in eight, and biliary and duodenal obstruction was bypassed. Ten patients als

Central mechanisms of chronic pain (neuralgias and certain other neurogenic pain).

Almost all supratentorial intracranial lesions which may effectively control chronic pain in man are ineffective for acute pain. There are at least 10 sites at which lesions producing no somatic sensory loss have often stopped the peculiarly agonizing chronic pain of advanced cancer. They include: (a) inferior posteromedial or subcaudate (preinnominate) frontal white matter; (b) supracallosal portion of cingulum; (c) thalamotomy of centrum medianum and parafascicularis nuclei; (d) thalamotomy of linear parasagittal type separating connections between lateral specific and medial nonspecific sen

Treatment of Actinic Keratosis with Photodynamic Therapy Using Red or Green Light: A Comparative Study.

Actinic keratosis (AK) is the most common in situ cancerous skin lesion. Compared with other approved treatment modalities photodynamic therapy is preferred by patients due to faster recovery and improved cosmetic outcome. However, pain during irradiation is an important drawback. The aim of this study was to compare the effectiveness and tolerability of topical aminolaevulinic acid-photodynamic therapy in the treatment of AK on the head using red and green light. Complete remissions after 3 sessions of photodynamic therapy at 2-week intervals following 9 months of observation were 91.67% for

Role of the Bone Microenvironment in the Development of Painful Complications of Skeletal Metastases.

Cancer-induced bone pain (CIBP) is the most common and painful complication in patients with bone metastases. It causes a significant reduction in patient quality of life. Available analgesic treatments for CIBP, such as opioids that target the central nervous system, come with severe side effects as well as the risk of abuse and addiction. Therefore, alternative treatments for CIBP are desperately needed. Although the exact mechanisms of CIBP have not been fully elucidated, recent studies using preclinical models have demonstrated the role of the bone marrow microenvironment (e.g., osteoclast

Retrospective Evaluation of Bone Metastases in Patients With Thyroid Malignancy: A Single-Center Experience.

Background Thyroid cancer is one of the five most common cancers causing bone metastasis. If there is an increase in serum thyroglobulin-antithyroglobulin levels in differentiated thyroid cancer or calcitonin levels in medullary thyroid cancer, patients should be evaluated for recurrence and distant metastasis. The skeleton is the second most common site of distant metastasis in thyroid cancer after the lung. Bone metastases cause pain, fractures, and spinal cord compression, severely reducing the quality of life. They are associated with poor prognosis. Bone metastases severely reduce the qua

The Use of Traditional, Complementary, and Integrative Medicine in Cancer: Data-Mining Study of 1 Million Web-Based Posts From Health Forums and Social Media Platforms.

BACKGROUND: Patients with cancer are increasingly using forums and social media platforms to access health information and share their experiences, particularly in the use of traditional, complementary, and integrative medicine (TCIM). Despite the popularity of TCIM among patients with cancer, few related studies have used data from these web-based sources to explore the use of TCIM among patients with cancer. OBJECTIVE: This study leveraged multiple forums and social media platforms to explore patients' use, interest, and perception of TCIM for cancer care. METHODS: Posts (in English) relat
