Postoperative Diet with an Oligomeric Hyperproteic Normocaloric Supplement versus a Supplement with Immunonutrients in Colorectal Cancer Surgery: Results of a Multicenter, Double-Blind, Randomized Clinical Trial.

(1) Background: For normo-nourished colorectal cancer patients, the need for immunonutrients after elective surgery is not known. (2) Methods: Multicenter, randomized, double-blind, phase III clinical trial comparing the postoperative diet with 200 mL oligomeric hyperproteic normocaloric (OHN; experimental arm) supplement vs. 200 mL immunonutritional (IN) (active comparator) supplement twice a day for five days in 151 normo-nourished adult colorectal-resection patients following the multimodal rehabilitation ERAS protocol. The proportions of patients with complications (primary outcome) and those who were readmitted, hospitalized for <7 days, had surgical site infections, or died due to surgical complications (secondary outcome) were compared between the two groups until postoperative day 30. Tolerance to both types of supplement and blood parameters was also assessed until day 5. (3) Results: Mean age was 69.2 and 84 (58.7%) were men. Complications were reported in 41 (28.7%) patients and the incidence did not differ between groups (18 (25%) vs. 23 (32.4%) patients with OHN and IN supplement, respectively; p = 0.328). No significant differences were found for the rest of the variables. (4) Conclusions: IN supplement may not be necessary for the postoperative recovery of colorectal cancer patients under the ERAS regimen and with normal nutritional status at the time of surgery.

Parkinsonism as presenting symptom of primary hyperparathyroidism: Improvement after surgery.

INTRODUCTION: Hypercalcemia can cause different neurological disorders, depending on the calcium level. We report an exceptional case of primary hyperparathyroidism presenting as neurological alteration and it has favourable outcome after parathyroidectomy. CASE REPORT: A 74-year-old woman presented with progressive cognitive deterioration and impaired motor function. The complementary tests showed hypercalcemia due to a parathyroid adenoma. Parathyroidectomy was performed with symptomatic improvement. CONCLUSION: Cognitive impairment of the elderly due to a parathyroid adenoma is underdiagnosed, behavioral changes and alterations of motor functions are attributed to age, dementia and frailty, representing a diagnostic challenge.

INTRODUCCIÓN: La hipercalcemia puede causar diferentes trastornos neurológicos, dependiendo de las concentraciones de calcio. Aportamos un caso excepcional de hiperparatiroidismo primario que se manifestó con deterioro neurológico rápidamente evolutivo y se resolvió mediante paratiroidectomía. CASO CLÍNICO: Mujer de 74 años que consultó por deterioro cognitivo progresivo y alteración de las funciones motoras. Las pruebas complementarias evidenciaron hipercalcemia debida a un adenoma paratiroideo. Se realizó paratiroidectomía, con mejoría sintomática. CONCLUSIÓN: El deterioro cognitivo del anciano por un adenoma paratiroideo está infradiagnosticado, pues los cambios de conducta y las alteraciones de las funciones motoras se atribuyen a la edad, la demencia y la fragilidad, suponiendo un reto diagnóstico.
