Food waste is a very important factor in the Food and Nutrition Unit, and it is essential to carry out a study of this indicator through leftovers and food scraps in order to verify the performance of the unit, the diner's view in relation to the menu offered in addition to the costs generated. The objective of the present study is to evaluate the size of the rest-intake produced in the institutional cafeteria. This cross-sectional research was carried out in a UAN of the Federal Institute of Piauí, Campus Piripiri at the beginning of the second semester of 2018, in the months of August, September and October. Food waste was monitored by diners for a period of 30 days, from Monday to Friday (except holidays). To obtain the residues, the remains of food thrown in the trash by diners during a period of thirty days were weighed. A waste index was found far above that acceptable in the literature, reaching a total of 297.80 kg, with an average of almost 10 kg per day and in relation to per capita data, approximately 56 grams of food were discarded. It is concluded that it is necessary to carry out constant educational actions to raise awareness of the target audience.

Context: Fahr’s syndrome is a clinical entity of primary or secondary causes characterized by neurological and/or psychiatric symptoms associated with abnormal calcifications in basal ganglia, cerebellum and cerebral cortex. Case report: G.M.A, female, 49 years-old, presented athetosis in the distal extremity of the right upper limb (RUL) in December 2020, without seeking for medical help. Known to be diabetic, hypertensive and with diastolic heart failure (HF), in February 2021 she presented decompensated HF associated with worsening of involuntary movements in the RUL. During investigation, abnormalities in serum levels of parathormone (PTH) and calcium were observed, in addition to bilateral calcifications in basal ganglia and thalamus in brain computed tomography (CT) without contrast. In March 2021, she was admitted to the University Hospital of the Federal University of Piauí, with maintenance of athetosis at the distal extremity of the RUL, in addition to oromandibular dyskinesia. Laboratory profile compatible with primary hypoparathyroidism and new brain CT without contrast with calcifications in basal ganglia and pulvinar of the thalamus, bilaterally, were confirmed. Intravenous calcium replacement and use of calcitriol were performed, with partial clinical improvement. Conclusions: Fahr’s syndrome is characterized by the presence of movement disorders (with highlights for parkinsonism and athetosis) and psychiatric symptoms (depression most commonly). Possible etiologies are primary (genetic) and secondary (mainly idiopathic or secondary hypoparathyroidism). Classic finding of symmetrical calcifications in base nuclei is seen on brain CT. Treatment is symptomatic and control of the underlying disease.
