Myasthenia gravis (MG) is a disease of neuromuscular junction and mainly autoimmune in aetiology. The state of thymus is a critical determinant for the prognosis. In this retrospective review study, we aimed at clarifying the relationship between the mode of clinical presentation of MG and the radiopathological classification of the thymus. We identified patients with MG from the database of our medical center from 1988 – 2017. The patients were classified into two groups according to their clinical presentation: those with a typical presentation with diurnal variation, and those with an atypical presentation of persistent weakness or respiratory failure from the beginning. The underlying thymic state was categorized into six groups: normal, abnormal by imaging (if no operation was performed), hyperplasia, benign thymoma, cortical type thymoma, and malignant thymoma. In total, 227 patients (133 females and 94 males) were included in the analysis, of whom 68% were classified into the typical presentation group. The atypical presentation correlated significantly with thymic categories (p = 0.014) and sex (p = 0.026) but not age at onset (p = 0.232). The atypical presentation was more common in the male patients and in those with thymic carcinoma.

Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.

Background: The bispectral index (BIS) may be unreliable to gauge anesthetic depth when dexmedetomidine is administered. By comparison, the electroencephalogram (EEG) spectrogram enables the visualization of the brain response during anesthesia and may prevent unnecessary anesthetic consumption. Methods: This retrospective study included 140 adult patients undergoing elective craniotomy who received total intravenous anesthesia using a combination of propofol and dexmedetomidine infusions. Patients were equally matched to the spectrogram group (maintaining the robust EEG alpha power during surgery) or the index group (maintaining the BIS score between 40 and 60 during surgery) based on the propensity score of age and surgical type. The primary outcome was the propofol dose. Secondary outcome was the postoperative neurological profile. Results: Patients in the spectrogram group received significantly less propofol (1585 ± 581 vs. 2314 ± 810 mg, P < 0.001). Fewer patients in the spectrogram group exhibited delayed emergence (1.4% vs. 11.4%, P = 0.033). The postoperative delirium profile was similar between the groups (profile P = 0.227). Patients in the spectrogram group exhibited better in-hospital Barthel’s index scores changes (admission state: 83.6 ± 27.6 vs. 91.6 ± 17.1; discharge state: 86.4 ± 24.3 vs. 85.1 ± 21.5; group–time interaction P = 0.008). However, the incidence of postoperative neurological complications was similar between the groups. Conclusions EEG spectrogram–guided anesthesia prevents unnecessary anesthetic consumption during elective craniotomy. This may also prevent delayed emergence and improve postoperative Barthel index scores.

Repetitive transcranial magnetic stimulation (rTMS) and intermittent theta-burst stimulation (iTBS) are evidenced-based treatments for patients with major depressive disorder (MDD) who fail to respond to standard first-line therapies. However, although various TMS protocols have been proven to be clinically effective, the response rate varies across clinical applications due to the heterogeneity of real-world psychiatric comorbidities, such as generalized anxiety disorder, posttraumatic stress disorder, panic disorder, or substance use disorder, which are often observed in patients with MDD. Therefore, individualized treatment approaches are important to increase treatment response by assigning a given patient to the most optimal TMS treatment protocol based on his or her individual profile. This literature review summarizes different rTMS or TBS protocols that have been applied in researches investigating MDD patients with certain psychiatric comorbidities and discusses biomarkers that may be used to predict rTMS treatment response. Furthermore, we highlight the need for the validation of neuroimaging and electrophysiological biomarkers associated with rTMS treatment responses. Finally, we discuss on which directions future efforts should focus for developing the personalization of the treatment of depression with rTMS or iTBS.

Background/Aims: Anti-reflux mucosal ablation (ARMA) is a promising endoscopic intervention for proton pump inhibitor (PPI)-dependent gastroesophageal reflux disease (GERD). However, the effect of ARMA on esophageal motility remains unclear. Methods: Twenty patients with PPI-dependent GERD receiving ARMA were prospectively enrolled. Comprehensive self-report symptom questionnaires, endoscopy, 24-hour impedance-pH monitoring, and high-resolution impedance manometry were performed and analyzed before and 3 months after ARMA. Results: All ARMA procedures were performed successfully. Symptom scores, including GerdQ (11.16 ± 2.67 to 9.11 ± 2.64, P = 0.026) and reflux symptom index (11.63 ± 5.62 to 6.11 ± 3.86, P = 0.001), improved significantly, while 13 patients (65%) reported discontinuation of PPI. Total acid exposure time (5.84 ± 4.63% to 2.83 ± 3.41%, P = 0.024) and number of reflux episodes (73.05 ± 19.34 to 37.55 ± 22.71, P < 0.001) decreased significantly after ARMA. Improved esophagogastric junction (EGJ) barrier function, including increased lower esophageal sphincter resting pressure (13.89 ± 10.78 mmHg to 21.68 ± 11.5 mmHg, P = 0.034), 4-second integrated relaxation pressure (5.75 ± 6.42 mmHg to 9.99 ± 5.89 mmHg, P = 0.020), and EGJ-contractile integral(16.42 ± 16.93 mmHg · cm to 31.95 ± 21.25 mmHg · cm, P = 0.016), were observed. Esophageal body contractility also increased significantly (distal contractile integral, 966.85 ± 845.84 mmHg · s · cm to 1198.8 ± 811.74 mmHg · s · cm, P = 0.023). Patients with symptom improvement had better pre-AMRA esophageal body contractility. Conclusions ARMA effectively improves symptoms and reflux burden, EGJ barrier function, and esophageal body contractility in patients with PPIdependent GERD during short-term evaluation. Longer follow-up to clarify the sustainability of ARMA is needed.

Boron neutron capture therapy and Y-90 radioembolization are emerging therapeutic methods for uncontrolled brain cancers and hepatic cancers, respectively. These advanced radiation therapies are heavily relied on theranostic nuclear medicine imaging before the therapy for the eligibility of patients and the prescribed-dose simulation, as well as the post-therapy scanning for assessing the treatment efficacy. In Taiwan, the Taipei Veterans General Hospital is the only institute performing the BNCT and also the leading institute performing Y-90 radioembolization. In this article, we present our single institute experiences and associated theranostic nuclear medicine approaches for these therapies.
