[Estimation of total body water from routine urea kinetics].

The comparison of total body water obtained by Watson formula with results of bioelectrical impedance (BIA) shows a fair approximation (Delta% = 1.0 +/- 8.45).

[Trace nutrients in total enteral nutrition: the basal status and longitudinal course].

Introduction: Previous studies demonstrated deficiencies of selenium and other micronutrients in patients receiving total enteral nutrition (TEN). The content and bioavailability of trace elements in enteral formulas can be suboptimal.

Material And Methods: Basal blood levels of some trace elements (copper, iron, selenium, zinc) and vitamins (B12, folic acid) were determined in twenty patients at the beginning of TEN.

[Nutritional assessment of aged patients with fractures of the proximal epiphysis of the femur].

Forty-two patients (M/F 9/33; age 78 +/- 10 years) were studied during Hospital stay for femoral neck fractures (16 neck, 26 pertrochanteric fractures). All underwent fracture surgery (internal fixation in 30, arthroplasty in 12 patients). Food intake was evaluated daily, supplemented with specific recipes.

[Aneurysm of the splenic artery. A clinical case and review of the literature].

The Authors report a case of splenic artery aneurysm (ASA) in a 64 years old woman. Most of patients affected by ASA are asymptomatic. Rupture represents a rare complication with high mortality rate.

Proposal of a new formula to calculate total urinary nitrogen from urea urinary nitrogen.

Urea urinary nitrogen (UUN) and total urinary nitrogen (TUN) were determined in 15 patients to study their relationship mainly in highly catabolic patients. The subjects were: 7 multiple trauma, 3 autologous bone-marrow transplant, 1 tetanus, 4 postcholecystectomy patients; 180 determination were made, 111 of which in highly catabolic phase (TUN > 15 g/day). TUN and UUN are well correlated (r = 0.
