Abstract

BACKGROUND Primary melanomas affecting the central nervous system are very rare, and melanomas originating in the spinal canal or origin of the spinal nerve root are even rarer. As a consequence, not much is known about this. CASE SUMMARY Here we report a case of primary malignant melanoma originating in the cervical spinal cord nerve root. A 64-year-old woman presented with symptoms of numbness in the right side of the neck, pain, and hypoesthesia in the right upper limb which persisted for 1 year. Neurological examination showed that the superficial sensation in the right upper limb had decreased with muscle strength of grade 4. Magnetic resonance imaging examination revealed a mass (approximately 2.5 cm × 1.4 cm × 1 cm) in the right side of the spinal canal in the C-2 plane. Based on findings obtained during operation, perioperative examination, pathological diagnosis, and the diagnostic criteria of primary central melanoma proposed by Hayward, the mass was confirmed to be a melanoma of intraspinal nerve root origin. CONCLUSION This is the first case of primary malignant melanoma originating from cervical spinal cord nerve roots and spread along the inside and outside of the spinal canal. The clinical relevance of this case is discussed to provide new insights into the differential diagnosis of intraspinal tumours. Further studies are needed to better understand the mechanisms driving the growth pattern and development of this type of tumour.

Abstract

Two Ligands (H (dec-ala) and H (dod-ala)) prepared from decyl chloride, lauroyl chloride, and amino acids (DL-alanine), reacted with Europium chloride in methanol solution, leading to two Europium (III) complexes of Eu (dec-ala)3 and Eu (dod-ala)3.Elemental analysis, NMR, and FT-IR spectra proved the elemental content, structural information of the synthesized Europium (III) complexes. The light absorption and luminescence properties were characterized by UV-vis and PL spectra analysis. Both complexes have excellent absorption capacity in the range of 200 nm-300 nm. The ideal excitation wavelengths of these complexes are at 394 nm, and the principal emission peaks are at 590 nm, 610 nm, 650 nm, and 698 nm, which correspond to 5D0 → 7F1, 5D0 →7F2, 5D0→7F3, 5D0→7F4, respectively.

Abstract

Objective: To assess the efficacy and safety of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) under general anesthesia and to provide the basis for clinical research related to DBS surgeries under general anesthesia., Methods: A total of 60 patients with primary Parkinson's disease who underwent DBS surgery between January 2019 and December 2021at West China Hospital were enrolled for the study. Among them, 30 had the surgery while they were asleep, i.e., under general anesthesia, and 30, while they were awake, i.e., under local anesthesia. All the patients underwent bilateral STN-DBS surgery. Bispectral index (BIS) was used to monitor and control the depth of anesthesia. Microelectrode recording (MER) technology was used to record the characteristic signals of the bilateral subthalamic nuclei and verify their location during the operation. All patients completed the implantation of deep electrodes, connecting wires, and implantable stimulation generator (IPG) at one time. Postoperative thin-slice CT scans were done to reconstruct electrode images and to verify the accuracy of electrode implantation. The Unified Parkinson's Disease Rating Scale-Ⅲ (UPDRS-Ⅲ) was used to evaluate the preoperative vs. postoperative improvement in motor symptoms, and the results of intraoperative MER and the occurrence of surgery-related complications were documented and analyzed., Results: All patients successfully completed the implantation surgery. The electrodes were accurately implanted at the right position and there was no significant difference between the general anesthesia group and the local anesthesia group in UPDRS-Ⅲ scores and medication dosage differences before and after the operation. No intracranial hemorrhage, cerebral infarction, or infection occurred after the operation, and 5 patients had temporary mental and behavioral abnormalities, which disappeared within 48 hours after the operation., Conclusion: The postoperative therapeutic effect of STN-DBS surgery for primary Parkinson's disease under general anesthesia is comparable to that of the traditional STN-DBS surgery under local anesthesia. When the operation is performed under general anesthesia, the incidence of surgery and anesthesia-related complications is low if patients are managed strictly, and patients would also experience improved surgical comfort., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Sciences).)
