AI Article Synopsis

  • Patient-controlled epidural analgesia (PCEA) using low thoracic placement is more effective in managing postcesarean pain than lumbar methods, as shown in a study of 189 women.
  • The low thoracic PCEA group reported significantly lower dynamic pain and better pain scores overall within 24 hours post-surgery compared to groups receiving lumbar PCEA or morphine.
  • While similar adverse effects were noted across all groups, the low thoracic PCEA group had fewer issues with prolonged lower extremity blockage and experienced faster gastrointestinal recovery.

Article Abstract

Unlabelled: Patient-controlled epidural analgesia (PCEA) or epidural morphine may alleviate postcesarean pain; however, conventional lumbar epidural insertion is catheter-incision incongruent for cesarean delivery.

Methods: In total, 189 women who underwent cesarean delivery were randomly divided into four groups (low thoracic PCEA, lumbar PCEA, low thoracic morphine, and lumbar morphine groups) for postcesarean pain management. Pain intensities, including static pain, dynamic pain, and uterine cramp, were measured using a 100 mm visual analog scale (VAS). The proportion of participants who experienced dynamic wound pain with a VAS score of >33 mm was evaluated as the primary outcome. Adverse effects, including lower extremity blockade, pruritus, postoperative nausea and vomiting, sedation, and time of first passage of flatulence, were evaluated.

Results: The low thoracic PCEA group had the lowest proportion of participants reporting dynamic pain at 6 h after spinal anesthesia (low thoracic PCEA, 28.8%; lumbar PCEA, 69.4%; low thoracic morphine, 67.3%; lumbar morphine group, 73.9%; < 0.001). The aforementioned group also reported the most favorable VAS scores for static, dynamic, and uterine cramp pain during the first 24 h after surgery. Adverse effect profiles were similar among the four groups, but a higher proportion of participants in the lumbar PCEA group (approximately 20% more than in the other three groups) reported prolonged postoperative lower extremity motor blockade ( = 0.005). In addition, the first passage of flatulence after surgery reported by the low thoracic PCEA group was approximately 8 h earlier than that of the two morphine groups ( < 0.001).

Conclusions: Epidural congruency is essential to PCEA for postcesarean pain. Low thoracic PCEA achieves favorable analgesic effects and may promote postoperative gastrointestinal recovery without additional adverse effects.

Development and validation of a scoring model for predicting surgical benefit in patients with Masaoka stage III/IV thymic carcinomas.

Gland Surg

Department of Thoracic Surgery and Oncology, State Key Laboratory of Respiratory Disease, National Clinical Research Center for Respiratory Disease, the First Affiliated Hospital of Guangzhou Medical University, Guangzhou, China.

Background: Thymomas and thymic carcinomas are rare and aggressive thymic tumors that are usually detected in advanced stages. Surgery is the mainstay of treatment; however, the role of surgery in advanced disease is controversial due to factors such as myasthenia gravis; thus, decisions about whether to perform surgical interventions are complex. Further studies need to be conducted to explore the potential benefits of surgery in the treatment of advanced thymic tumors.

Background: Primary hyperparathyroidism (pHPT) is the third most common endocrine disease, affecting predominantly postmenopausal women. About 85% of cases are caused by a solitary parathyroid adenoma which leads to a hypersecretion of the parathyroid hormone (PTH) and consequently to elevated serum calcium concentrations. Parathyroidectomy is the only curative treatment.

Prevalence of thoracic degenerative MRI findings and association with pain and disability: a systematic review.

Skeletal Radiol

January 2025

Center for Muscle and Joint Health, Department of Sports Science and Clinical Biomechanics, University of Southern Denmark, Campusvej 55, 5230, Odense M, Denmark.

Objectives: To systematically review the literature on the prevalence of degenerative MRI findings in the thoracic spine and their association with pain and disability.

Materials And Methods: The Medline, EMBASE, CINAHL, and CENTRAL databases were searched. Two independent reviewers screened the articles, extracted the data, and assessed the risk of bias (RoB) using a modified version of the Hoy tool for articles on prevalence and QUADAS-2 for articles on associations.

[Evidence for the extent and oncological benefit of lymphadenectomy for esophageal cancer].

The prognosis for esophageal cancer is determined in particular by the depth of infiltration (T stage) and lymph node metastasis (N status). In patients with locally advanced tumors, surgical resection is the current standard. The extent of the lymphadenectomy depends on the localization of the tumor, analogous to the choice of surgical technique.

Background: The relationship between low-density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (ASCVD) is well-established. Recently, non-high-density lipoprotein cholesterol (non-HDL-C) has been validated as a superior predictor of ASCVD, especially in individuals with mild to moderate hypertriglyceridemia. The EPHESUS study evaluated real-life hypercholesterolemia management and awareness of non-HDL-C in cardiology outpatient practices.
