Twenty-Three Months Repetitive Transcranial Magnetic Stimulation of the Primary Motor Cortex for Refractory Trigeminal Neuralgia: A Single-Case Study

Treatment refractory or recurrent trigeminal neuralgia (TN) is a severe chronic pain illness. Single-session repetitive transcranial magnetic stimulation (rTMS) has been shown to elicit analgesic effects in several craniofacial pain syndromes, including TN. However, the safety and long-term effect of multi-session rTMS for TN have yet to be fully explored. In this study, we present a case of a patient with medical treatment-refractory TN after microvascular decompression. The patient volunteered to undergo 73 sessions of 10 Hz rTMS over 23 months. Neurovagination was used for precise localization and stimulation of the hand and face representation at the left motor cortex. The numeric pain intensity scores derived using the visual analog scale served as a daily index of treatment efficacy. The patient experienced a significant weekly reduction in pain scores, cumulating in 70.89% overall pain relief. The medication dosages were reduced and then discontinued toward the end of the intervention period. No severe adverse events were reported. From our results, we can conclude that the longitudinal multi-session application of rTMS over the hand and face area of M1 is a safe and effective method for producing long-lasting pain relief in TN. Using rTMS may thus prove helpful as an adjunct to conventional methods for treating pain in TN

Crohn’s disease in human immunodeficiency virus-infected patient: A case report

BACKGROUND Inflammatory bowel disease (IBD) is an autoimmune condition treated with immunosuppressive drugs. However, the need for immune system suppression becomes questionable when infection with the human immunodeficiency virus (HIV) occurs simultaneously and impacts the course of IBD. Our reported case represents the clinical course, prescribed treatment and its effect, as well as clinical challenges faced by physicians in a combination of such diseases. We also present a comprehensive literature review of similar cases. CASE SUMMARY A 49-year-old woman suffering from a newly diagnosed Crohn’s disease was hospitalized due to exacerbated symptoms (abdominal pain, fever, and weight loss). During her hospital stay, she tested positive for HIV. With conservative treatment, the patient improved and was discharged. In the outpatient clinic, her HIV infection was confirmed as stage C3, and antiretroviral treatment was initiated immediately. That notwithstanding, soon the patient was rehospitalized with pulmonary embolism and developed a series of complications because of the subsequent coexistence of IBD and HIV. After intensive and meticulous treatment, the patient’s condition has improved and she remains in remission. CONCLUSION The paucity of studies and data on the coexistence of HIV and IBD leaves clinicians doubting the optimal treatment options
