Corticobasal syndrome (CBS) is a rare progressive neurodegenerative disease characterized by a combination of asymmetric motor symptoms and non-motor symptoms. CBS is poorly responsive to levodopa. Non-pharmacological strategies have been found to be useful as components of a multidisciplinary therapeutic approach for patients with CBS. The purpose of this study was to investigate the effects of virtual reality training in addressing symptoms of CBS. A 64-year-old man was clinically diagnosed as CBS one year after the onset of complaints. Positron emission tomography (PET) scan showed asymmetrical hypometabolism in the right thalamus and basal ganglia. The patient was evaluated for balance, gait, mobility, and cognition 1 week before, 1 week after, and 1 year after 6 weeks of training, 3 times weekly (18 sessions in total). All clinical outcomes and PET result had improved after the intervention; cognition and balance were maintained after 1 year. Additionally, the asymmetric hypometabolism, which had been detectable on the PET scan, became normal, and a relative improvement was noted in the visual evaluation of cortical involvement. Virtual reality may address different aspects of motor and cognition and possibly brain metabolic changes that can affect the course of the disease in patients with CBS.

A 69 year-old male patient with a history of malignant mesothelioma treated with chemotherapy and surgical resection with removal of the right lung and right pleural pneumonectomy was clinically in remission for 1 ½ years. A positron emission tomography (PET) scan revealed limited uptake in the right pleural space, thought to represent post-surgical changes, and uptake in the left thyroid lobe. Thyroid ultrasound revealed a solid left lobe nodule with peripheral vascularity and absent microcalcifications. Fine needle aspiration cytology showed a microfollicular arrangement of cytologically bland cells with variable Hürthle cell changes initially interpreted as suspicious for Hürthle cell neoplasm. Review at multidisciplinary conference raised the possibility of metastatic mesothelioma, supported by immunohistochemical studies in the cell block. The patient opted for left hemithyroidectomy with isthmusectomy which confirmed malignant mesothelioma. Repeat PET scan 6 months later revealed no further uptake in the thyroid bed, with limited uptake in the right pleural space. Metastatic tumors to the thyroid are uncommon with only one previous description of metastasis to the thyroid by mesothelioma. Metastasis of cytologically low grade tumors such as mesothelioma present problems for cytology due to the potential for overlap with the variable appearances of thyroid neoplasms. The value (if any) of ancillary tests, including mutation testing, expression profiling and immunohistochemistry is discussed.

Background: Changes in sexual behaviors in frontotemporal dementia (FTD) are common and multifaceted, but not well characterized. Objective: To characterize changes in sexual behaviors and intimacy in FTD compared to corticobasal syndrome (CBS) and normal controls (NC), and to evaluate the neuroanatomical associations of these changes. Methods: Spouses of 30 FTD patients, 20 CBS patients, and 35 NC completed the Sexual Symptoms in Neurological Illness and Injury Questionnaire (SNIQ), which captures changes in sexual interest, inappropriate sexual behaviors, and prosocial sexual behaviors. 25 patients with FTD and 14 patients with CBS also received 18-flouorodeoxyglucose positron-emission topography (18FDG-PET) scans to determine the metabolic changes associated with these symptoms. Results: FTD patients showed a greater increase in inappropriate sexual behaviors than CBS patients [p = 0.009] and NC [p < 0.001] and a greater decrease in prosocial sexual behaviors than CBS patients [p = 0.026] and NC [p < 0.001]. Groups did not differ in change in sexual interest. Among both patient groups, the most common change was decreased prosocial sexual behaviors p < 0.01. Hypometabolism in Brodmann’s Area 10 (BA10), within the right frontal pole, correlated with decreased prosocial sexual behaviors [p(FWE-corr) <0.05, k = 44]. No anatomical associations were found with other sexual changes. Conclusion: Decreased prosocial sexual behavior was associated with hypometabolism in BA 10, an area tied to social knowledge and theory of mind, supporting the idea that changes reflect social-cognitive deficits due to frontal dysfunction.

Mine Roof

According to the research of Heinrich, DuPont Company and U.S. National Security Council, more than 80% of accidents are caused by individuals’ unsafe acts. In order to eliminate unsafe acts causing mine roof accidents, 10 types of common unsafe acts were summarized and 4 kinds occur most frequently based on 40 typical roof accidents, these 4 kinds of common unsafe acts are not choose the right work methods(20%), not prevent unsafe acts of others(17.5%), not check the environment(15%), nobody observe roof while working(12.5%). And then, corresponding safe acts are given. Finally, 4 types of improving measures are proposed, they are unsafe acts demonstration via 3-D animation, virtual reality training, unsafe acts knowledge contest and pithy formula teaching.

Gastrointestinal stromal tumors (GISTs) are known to originate specifically from the intestinal cells of Cajal located in the gastrointestinal mesenchyme. GISTs developing outside of the digestive tract have barely been reported. We encountered a first case of large primary GISTs in the liver with cystic changes. A 63-year-old man with a past history of brain infarction visited our hospital. The computed tomography (CT) revealed a 6-cm and a 10-cm mass in the right and the caudal lobe of the liver, respectively. These tumors have marginal enhancement in the arterial phase; however, they presented as hypodense in the internal tumor sites. Both liver tumors had cystic changes. Gastrointestinal examinations using endoscopy revealed no other gastrointestinal tumors, and [18F]-fluoro-2-deoxy-D-glucose positron emission tomography/CT revealed multiple bone metastases in addition to the liver tumors. The liver tumor specimens were composed of spindle cells, and the immunohistochemical staining for c-Kit and for DOG1, as discovered on GIST, was positive. The patient was diagnosed with primary hepatic GIST with cystic changes.

We report a case of a young woman with Cushing’s syndrome (CS), in whom although endocrine investigations and negative pituitary imaging were suggestive of ectopic ACTH secretion, the results of inferior petrosal sinus (IPS) sampling after coricotropin-releasing hormone (CRH) stimulation were suggestive of pituitary ACTH hypersecretion. 111In-labelled octreotide and high-resolution computer tomography (CT) revealed a lesion possibly responsible for the ACTH source in the thymus. Thymectomy confirmed concomitant ectopic CRH and probable ACTH production by a thymic neuroendocrine carcinoma. After an 8-year remission period the patient developed a clinical and biochemical relapse. A high-resolution computed tomography (CT) scan of the thorax showed a 2-cm nodule in the thymic bed, which was positive on a [18F]fluoro-2-deoxy-d-glucose ([18F]FDG) positron emission tomography (PET) scan. However, a repeated thymectomy did not result in remission. A repeat [18F]FDG PET study showed persistent disease in the thymic bed and also uptake in the adrenals. The patient underwent bilateral adrenalectomy, which resulted in clinical remission. A further [18F]FDG PET scan 8 months later showed no progression of the thymic tumor and confirmed complete excision of the adrenals. This is a rare case of concomitant CRH and ACTH secretion from a thymic carcinoid tumor; the case illustrates the usefulness of functional imaging with [18F]FDG PET in the diagnosis, management and follow-up of neuroendocrine tumors.

Elderly Onset

Introduction Rheumatoid arthritis (RA) disease is a systemic progressive inflammatory autoimmune disorder. Elderly-onset RA can be assumed as a benign form of RA. Until recently, face-to-face therapeutic sessions between health professionals and patients are usually the method of its treatment. However, during pandemics, including coronavirus disease 2019 (COVID-19), teletherapeutic sessions can extensively increase the patient safety especially in elderly patients who are more vulnerable to these infections. Thus, the aim of this study was to evaluate a novel teletherapy approach for management of elderly patients suffering from RA by utilizing laser acupuncture. Methods A teletherapy system was used for management of elderly patients suffering from RA. Sixty participants were allocated randomly into two groups and the ratio was 1:1. Patients in the first group were treated with laser acupuncture and telerehabilitation sessions, which consisted of aerobic exercise and virtual reality training. Patients in the second group received telerehabilitation sessions, which consisted of aerobic exercise and virtual reality training. Evaluation of patients was done by using the Health Assessment questionnaire (HAQ), the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire, and the analysis of interleukin-6 (IL-6), serum C-reactive protein (CRP), plasma adenosine triphosphate (ATP) concentration and plasma malondialdehyde (MDA). Results A statistically significant difference was found in CRP, RAQoL, IL-6 and MDA between the pre- and post-treatments in the first group ( p < 0.05) favouring the post-treatment group, while the HAQ showed a statistically significant difference between pre- and post-treatments ( p < 0.05) in both groups. Statistically significant post-treatment differences were also observed between the two groups ( p < 0.05) in RAQoL, CRP, ATP and MDA, favouring the first group. Discussion Laser acupuncture teletherapy could be suggested as a reliable treatment method for elderly patients suffering from RA, as it can provide a safe and effective therapeutic approach. Teletherapy provided safer access to health professionals and patients while giving a high patient satisfaction value with a relatively lower cost (ClinicalTrials.gov Identifier: NCT04684693).
