Jikoshu-Kyofu (JKF) is a subtype of Taijin-Kyofu-Sho (TKS), a form of social anxiety first described in Japanese sufferers. Unlike the Diagnostic and Statistical Manual of Mental Disorders - 4th edition text revised definition of social anxiety disorder, TKS is characterised by a fear of offending others, whereas in the case of JKF, it is the fear of giving off a smell, thus causing offence. We describe the symptoms of JKF in a young woman who was treated with cognitive behavioural therapy (CBT). After only four sessions, the patient's anxiety ratings, as measured on the Social Phobia Inventory and Brief Social Phobia Scale, dropped considerably. This case illustrates the successful treatment of a patient with JKF-like symptoms using CBT.

Objective: Colony-stimulating factor 1 receptor-related leukoencephalopathy (CSF1R-L) is a rare adult-onset leukoencephalopathy. Reports of CSF1R-L patients from the Indian subcontinent remain limited. We aimed to report four patients with genetically confirmed CSF1R-L from four Asian Indian families and described their clinical, molecular, and radiological features. Methods: All patients underwent clinical examination, brain magnetic resonance imaging, and whole-exome sequencing to identify causative variants in the CSF1R gene. We also reviewed published reports of Indian patients with CSF1R-L. Results: The age at enrollment ranged from 34 to 40 years. The duration of symptoms ranged from 11 months to 2 years. The chief clinical phenotype in three patients was a rapidly evolving cognitive-behavioral syndrome combined with atypical parkinsonism, and asymmetrical spastic tetraparesis was observed in one patient. We identified four different variants (three missense variants and one in-frame deletion). Radiological findings revealed white matter involvement and diffusion restriction involving the subcortical white matter and pyramidal tracts. Conclusion We expand the literature on CSF1R-L patients from India by reporting four new cases.
