An experiment in nine patients tested the similarities and interactions between the paresthesias of Guillain-Barré syndrome (GBS) and tourniquet-induced compression paresthesias. During brachial compression, GBS paresthesias diminished in five of seven patients and new paresthesias occurred in two patients with purely motor GBS. Beginning 1 to 4 minutes after release of the cuff, all patients had new paresthesias, distinguishable from GBS symptoms. The novel finding was that GBS paresthesias diminished or ceased during the postcompression period in five of seven patients. Demyelinated peripheral nerves in GBS apparently can generate and transmit the spontaneous activity associated with paresthesias in the postcompression period. Interference occurs between the two types of paresthesias, possibly because both are caused by spontaneous ectopic activity in tactile nerves.

Department of Rehabilitation Medicine, Kyoto University Graduate School of Medicine, Kyoto, JPN.
Alcohol use disorders can cause peripheral and central neurological disorders with symptoms such as pain, numbness, paresthesia, and dysesthesia, often impairing walking ability. However, effective treatments for alcohol-related peripheral neuropathy are yet to be identified. This case report highlights the successful use of dysesthesia-matched transcutaneous electrical nerve stimulation (DM-TENS) and aerobic exercise in a 53-year-old woman with alcohol-related peripheral neuropathy who presented with severe pain and walking difficulties.

Background: Neuromyelitis optica spectrum disorders (NMOSDs) are degenerative diseases frequently associated with severe recurrences and high risk of progressive disability. In this report, we describe an unusual case of a patient with the coexistence between NMOSD and mixed connective tissue disease (MCTD).
Case Description: A 58-year-old Caucasian man was admitted to the Emergency Department (ED) with low back pain and walking inability.

Background: Sensory disorders of the inferior alveolar nerve, often arising from dental procedures, markedly impact the quality of life of patients. This article proposes a scoping review to analyze emerging trends in pharmacological treatment for these disorders, addressing scientific gaps and clinical practices.
Material And Methods: The review followed the PRISMA-ScR protocol, conducting data searches across various databases, including PubMed and Cochrane, until March 2024.

: The aim of this study is to identify the most accurate and consistent landmarks for determining the precise location of the mandibular foramen (MF) and the mandibular ramus, suggesting appropriate adjustments to anesthesia techniques based on these variations in order to improve the success rate of the inferior alveolar nerve (IAN) block. : CT scans of the mandibles from 100 patients were analyzed to measure the distance between the MF and various landmarks, including the sigmoid notch, gonion, posterior and anterior margins of the ramus, temporal crest, and the mandibular ramus height from the condyle to the gonion. The width of the mandibular ramus was also assessed, with correlations made to age and gender.

To date, there have been no studies on the dynamics of areas of pain, paraesthesia and hypoesthesia after the use of various transcutaneous electrical nerve stimulation in the treatment of meralgia paresthetica. In this pilot study, we observed 68 patients with obesity-related bilateral meralgia paresthetica. Pain syndrome, paraesthesia symptoms, and hypoesthesia were evaluated using 10-point scores.
