Burning Mouth Syndrome (BMS) is defined as a chronic orofacial pain syndrome, without evidence of mucosal lesions and other clinical signs of disease or laboratory abnormalities. Patients with BMS complain of burning pain in the mouth, xerostomia and taste disturbances. It is more common among women and the median age of occurrence is about 60 years. BMS may be primary or secondary to other diseases. The mainstay in the treatment of BMS includes antidepressants, benzodiazepines, and anticonvulsants. A few cases of BMS caused due to medication have been reported. The causative drugs include angiotensin-converting enzyme inhibitors, anticoagulants, antipsychotics, antiretrovirals, and benzodiazepines. This is a case report of a patient on antidepressants who developed symptoms of BMS thereby causing a dilemma in management.

Purpose: Burning mouth syndrome (BMS) is a chronic pain condition involving the oral and perioral regions, often characterized by a burning sensation and pain in elderly patients. In this study, we investigated the effectiveness of pharmacological agents for the treatment of BMS patients through a retrospective chart review. Methods: We enrolled 61 BMS subjects (57 females, 4 males; $66.4{\pm}10.9$ years of age) from among consecutive patients treated pharmacologically from January 2014 to June 2015 at Chonnam National University Dental Hospital. Patients with secondary BMS associated with local factors were excluded. The treatment period, number of pharmacological agents tried, and effectiveness of the drugs administered to each subject were analyzed. Results: The mean treatment period for the management of BMS was 2.5 months. More than three agents were tried to control BMS symptoms in 17 subjects (27.9%); two agents were used in 10 subjects (16.4%), and a single agent in 24 subjects (39.3%). Clonazepam was prescribed most frequently and was effective at relieving symptoms in 30 of 39 subjects (76.9%). Paroxetine was moderately effective, relieving symptoms in 7 of 17 subjects (41.2%). Some of the subjects benefited from tricyclic antidepressants, gabapentin, and lipoic acid. A topical local anesthetic used to supplement other systemic agents had ameliorating effects in four of six subjects. Conclusions: Within the study limitations, clonazepam was the most effective drug and antidepressants were efficacious in some subjects for relieving the symptoms of BMS. These pharmacological agents could be considered as first-line drugs for the management of BMS.

Recently, secondary batteries, commonly known as rechargeable batteries, find widespread applications across various industries. Particularly valued for their compact and lightweight characteristics, they play a crucial role in diverse portable electronic devices such as smartphones, laptops, and tablets, offering high energy density and efficient charge-discharge capabilities. Moreover, they serve as vital components in electric vehicles and contribute significantly to the field of renewable energy as part of Energy Storage Systems(ESS). However, despite advancements in this technology, issues such as reduced lifespan, cracking, damage, and even the risk of fire can arise due to excessive charging and discharging of secondary batteries. To address these challenges, Battery Management System(BMS) are employed to protect against overcharging and improve overall performance. Nevertheless, understanding the protective range settings of BMS using lithium-ion batteries, the most commonly used secondary batteries, and lead-acid batteries can be challenging. Therefore, this paper aims to utilize a battery charge-discharge tester and simulator to investigate the charging and discharging characteristics of lithium-ion batteries and lead-acid batteries, addressing the associated challenges of reduced lifespan, cracking, damage, and fire hazards in secondary batteries.

Purpose: The objective of this retrospective pilot study was to evaluate the effectiveness of Gabapentin in patients with primary burning mouth syndrome (BMS). Methods: Ten subjects were diagnosed with primary BMS (8 women and 2 men). The mean age was 60.1 years. They had clinical examination to exclude local factors such as the presence of Candida species, xerostomia, lichen planus, etc. They also underwent hematological examination to exclude secondary BMS due to systemic disorders. Pain was assessed by patients on an 11-point numerical rating score system (0 to 10). Gabapentin was administered at a starting dose of 300 mg/day, slowly titrated up to maximum of 1,800 mg/day. All patients were treated for 4 weeks. Results: One half of the patients (n=5) obtained reduction in pain over the treatment period. Four patients reported no reduction in pain symptoms. One patient reported that symptoms were worsening. The average pain score before the treatment was 6.3 and after the treatment was 5.25. No significant relationship was detected between pretreatment and posttreatment pain score. Only one patient noted mild side effect (dizziness). Conclusions: This retrospective pilot study provides no preliminary evidence that Gabapentin has effect in the management of BMS. However, further research (well-designed, randomized, and controlled trial with large sample) would be needed to investigate the efficacy of Gabapentin in treatment of BMS.
