Cognitive disorders in migrants: retrospective analysis in a Center for Cognitive Disorders and Dementia in Milan.

BACKGROUND: The number of migrants with dementia in Italy might increase considerably over the coming years due to the increasing flow of immigration and the aging of the population. AIMS: We retrospectively registered rate and characteristics of demented migrant outpatients referred to one hospital in Milan from 2001 to 2017. METHODS: Information about country of origin of migrants attending general neurology and memory clinics was obtained from their Italian tax code. Socio-demographic, cultural, and clinical characteristics were derived from their medical records. RESULTS: Migrants with cognitive decline represented a minimal fraction (3.1%) of demented outpatients, but a grow rate of 400% was registered within the period of observation. A linguistic barrier resulted as the main obstacle for the application of available diagnostic tools for dementia. DISCUSSION/CONCLUSION: Given the above-reported data, the implementation of strategies (such as transcultural diagnostic instruments) and policies dedicated to this growing health problem appears a priority for our health systems.

Fibular nerve palsy after hip replacement: Not only surgeon responsibility. Hereditary neuropathy with liability to pressure palsies (HNPP) a rare cause of nerve liability.

Mononeuropathy after surgery may occur and hereditary neuropathy with liability to pressure palsies is a possible pathological condition related to paresis after hip surgery. We present a case of 66-year-old man presenting severe weakness at inferior limb muscles after hip prosthesis revision. Clinic and electrophysiology showed severe right fibular nerve damage and ultrasound found a marked enlargement of the same nerve, associated with focal enlargements in other nerves. A diagnosis of hereditary neuropathy with liability to pressure palsies was suspected and confirmed by genetic test. The patient gradually recovered returning to a normal daily active life. Ultrasound was crucial for diagnosis. The suspicion and diagnosis of latent neuropathy, which can occur after surgical intervention, may lead to a better understand of the risks of the surgery, specific for the patient, and avoid the wrong attribution to surgical malpractice.
