The social cost of chronic kidney disease in Italy

This study aims to estimate the mean annual social cost per patient with chronic kidney disease (CKD) by stages 4 and 5 pre-dialyses and cost components in Italy. The multicenter cross-sectional study included all adult outpatients in charge of the 14 main Nephrology Centers of Tuscany Region during 7 weeks from 2012 to 2013. Direct medical costs have been estimated using tariffs for laboratory tests, diagnostic exams, visits, hospitalization and prices for drugs. Non-medical costs included expenses of low-protein special foods, travel, and formal and informal care. Patients' and caregivers' losses of productivity have been estimated as indirect costs using the human capital approach. Costs have been expressed in Euros (2016). Totals of 279 patients in stage 4 and 205 patients in stage 5 have been enrolled. The estimated mean annual social cost of a patient with CKD were a,notsign7422 (+/- a,notsign6255) for stage 4 and a,notsign8971 (+/- a,notsign6503) for stage 5 (p < 0.05). Direct medical costs were higher in stage 5 as compared to stage 4; direct non-medical costs and indirect costs accounted, respectively, for 41 and 5 % of the total social cost of CKD stage 4 and for 33 and 9 % of CKD stage 5. In Italy, the overall annual social cost of CKD was a,notsign1,809,552,398 representing 0.11 % of the Gross Domestic Product. Direct non-medical costs and indirect costs were weighted on the social cost of CKD almost as much as the direct medical cost. Patients, their families and the productivity system sustain the burden of the disease almost as much as the healthcare system. © 2016, The Author(s)

Lesion Patterns and Possible Implications for Recovery in Acute Unilateral Vestibulopathy

Objective:To assess patterns of end-organ involvement in acute unilateral vestibulopathy (AUV) and to define the recovery.Study Design:Retrospective chart review.Setting:Tertiary academic referral hospital.Patients and Interventions:Fifty-nine patients fulfilling clinical criteria for AUV and evaluated using the caloric vestibular test, video head impulse test, and both cervical and ocular vestibular evoked myogenic potentials, up to 10 days from symptoms onset were included.Main Outcome Measures:Vestibular tests and requirements for vestibular rehabilitation were analyzed.Results:The most affected end-organ was the horizontal canal (97%), followed by the anterior canal (83%), utricle (73%), posterior canal (46%), and saccule (44%). Nineteen (32%) patients exhibited complete receptors lesion, while 13 (22%) exhibited damage to receptors connected with the superior division of the vestibular nerve (VN). The proportion of patients who underwent vestibular rehabilitation was higher in the latter two groups (58% for both). Partial involvement of the receptors innervated by both the division of the VN, rather than by its superior division, was detected in 22 and 24% of patients, respectively. Total or partial damage to receptors innervated by the inferior VN was not found.Conclusion:Deeper understanding of AUV may be achieved through identification of its patterns. Slightly more than one-half of AUV cases seemed to be associated with a nerve lesion, with a worse clinical outcome. The remaining patients exhibited selective involvement of vestibular receptors, more probably consistent with an intralabyrinthine lesion pattern and experienced better spontaneous recovery
