Tourette's Syndrome cervical dystonia induced occipital neuralgia remedied by peripheral nerve stimulation: A case report / Síndrome de Tourette, distonia cervical induzida por neuralgia occipital remediada por estimulação nervosa periférica: relato de caso

BACKGROUND: Dystonia is uncommon in Tourette's syndrome, and occipital neuralgia secondary to Tourette's dystonia is more rare, affecting quality of life. Occipital peripheral nerve stimulation (PNS) is an excellent alternative by being adjustable and minimally invasive. Our case demonstrates occipital PNS as an effective option for refractory Tourette's dystonia. CASE PRESENTATION: A thirty-four-year-old male with poorly controlled Tourette's cervical dystonia presented with severe occipital neuralgia. Various medications were prescribed including propranolol and amitriptyline, and bilateral third-occipital nerve rhizotomies and occipital nerve blocks were trialed. Distal nerve blocks at the occipital protuberance were most effective. Therefore, an occipital PNS trial was done, and a PNS was implanted with no complications. Upon follow-up, the patient reported drastic pain reduction. CONCLUSION: Our case illustrates neuromodulation benefits for a rare presentation of refractory occipital neuralgia secondary to Tourette's-related dystonia. Occipital PNS should be considered for refractory cases because it is safe, easy to implant, and effective.

FUNDAMENTO: A distonia é incomum na síndrome de Tourette, e a neuralgia occipital secundária à distonia de Tourette é mais rara, afetando a qualidade de vida. A estimulação do nervo periférico occipital (SNP) é uma excelente alternativa por ser ajustável e minimamente invasiva. Nosso caso demonstra o SNP occipital como uma opção eficaz para a distonia de Tourette refratária. APRESENTAÇÃO DO CASO: Um homem de 34 anos com distonia cervical de Tourette mal controlada apresentou neuralgia occipital grave. Vários medicamentos foram prescritos, incluindo propranolol e amitriptilina, e foram testadas rizotomias bilaterais do nervo terceiro-occipital e bloqueios do nervo occipital. Os bloqueios dos nervos distais na protuberância occipital foram mais eficazes. Portanto, foi feito um ensaio de PNS occipital e um PNS foi implantado sem complicações. Após o acompanhamento, o paciente relatou redução drástica da dor. CONCLUSÃO: Nosso caso ilustra os benefícios da neuromodulação para uma apresentação rara de neuralgia occipital refratária secundária à distonia relacionada a Tourette. O PNS occipital deve ser considerado para casos refratários porque é seguro, fácil de implantar e eficaz.

A Prospective Cross‑sectional Study to Analyze the Effect of Transnasal Sphenopalatine Ganglion Blockin Carcinoma Buccal Mucosa Patients

Introduction: Cancer pain is known to be one of the Most severe pain anyone in life and is the primary reason for discontinuation of treatment.Sphenopalatine ganglion block (SPGB) can be useful in alleviating pain of carcinoma buccal mucosa. The study aims to analyze the effect of transnasal SPGB in pain management of patients suffering from carcinoma buccal mucosa. Materials and Methods: It was a hospital‑based study done on 150 patients with carcinoma buccal mucosa using a prospective cross‑sectional study design. To do statistical analysis, paired t‑test was used having SPSS software. Results: On visual analogue scale, intensity of pain was found to be notably reduced from 7.42±2.02 to 3.45±1.21 (P < 0.0001), after first sitting. Preprocedure and postprocedure morphine requirement were 90.24 ± 30.24 and 60.42 ± 0.93 mg/day (P > 0.05) At the conclusion of study, the results were found to be statistically significant. Conclusion: Transnasal SPGB is beneficial in improving patient compliance and reducing pain scores and morphine requirement in patients suffering from carcinoma buccal mucosa

Usefulness of MgSO4 in the Field of Anesthesia and Pain Medicine

Perioperative hypomagnesemia is common in major surgical patients. MgSO4 infusion may be useful in the treatment of arrhythmia, asthma and postoperative shivering and in the prevention of hemodynamic stimulation associated with endotracheal intubation and surgery of pheochromocytoma. It may also enhance muscular relaxation and improve postoperative analgesia. It can be an ideal adjunct to propofol-remifentanil-based total intravenous anesthesia.

Pain Management in Cancer Patients

In 1990, WHO developed the analgesic ladder for rational titration of medication for cancer pain, because 50% of patients with cancer and 75% of those with advanced malignant disease will likely experience moderate to severe pain according to the report of Agency for Health Care Policy and Research(AHCPR). Actually, However, about 62% of cancer pain are not adequately controlled for several reasons, such as inappropriate dosage of analgesics, strict regulation of narcotics, physicians' indifference to cancer pain, and lack of knowledge for pain assessment in Korea. In this chapter, I would like to introduce techniques to relieve pain in cancer patients using some kinds of analgesics including narcotics, adjuvants, and verve blocks. By using medications and nerve block, more than 95% of cancer pain can be relieved effectively. One may be unfamiliar with the fact that cancer pain is not single isolated entity itself, but has multiple etiologies that may or may not be directly related to the cancer itself. This fact has resulted in the awareness that the treatment must be directed toward the perceived etiology of pain once it is identified. Pain does not occur in a vacuum ; the psychological manifestations of pain must be treated as well as any possible side effects of the treatment. With regards to cancer pain, this is generally stressed in all fields of medicine, particularly in the field of pain medicine.
