ABSTRACT

A incidência da tuberculose tem diminuido nos últimos anos. No entanto, em consequência da sua apresentaçäo insidiosa, permanece clinicamente importante. As menifestações radiológicas säo variáveis e seu reconhecimento é de suma importância. Nos estádios iniciais, a urografia excretora pode ser normal, mesmo na presença de culturas positivas para bacilos álccol-ácido resistentes. Mais tarde, pode haver irregularidade dos cálices. O uso da ultra-sonografia na avaliaçäo da tuberculose renal tem sido esporadicamente descrito na literatura. O ultra-som pode determinar o local da obstruçäo na presença de um rim excluso. A tomografia computadorizada pode demonstrar a presença e o local da obstruçäo. Qualquer vestígio de funçäo renal pode ser avaliado após injeçäo de contraste. A facilidade de detectar calcuificações supera á do raio-X. O parênquima renal também pode ser avaliado no rim abstruído.

ABSTRACT

Our objective was to compare food intake and nutritional status of Pemphigus Foliaceus patients (PG) on long term glucocorticoid therapy to a Control Group (CG). Fourteen PG female inpatients receiving prednisone (0.33 + or - 0.22mg/kg) for at least 12 months and twelve CG subjects were submitted to nutritional evaluation, including anthropometry, urinary creatinine determination and serum biochemical measurements, besides 48-h-based food intake records. Groups were compared by Chi-square, Mann-Whitney and "t" tests. PG patients and CG were paired, respectively, in relation to age (24.7 + or - 14.1 vs. 22.0 + or - 12.0 years), body mass index (25.8 + or - 6.4 vs. 24.0 + or - 5.6kg/m2), daily protein intake (132.9 + or - 49.8 vs. 95.2 + or - 58.9g), and serum albumin (median; range) (3.8; 3.5-4.1 vs. 3.8; 3.6-5.0g/dl). However, PG patients had lower height-creatinine index (64.8 + or - 17.6 vs. 90.1 + or - 33.4 percent), and higher daily energy (3080 + or - 1099 vs. 2187 + or - 702kcal) and carbohydrate (376.8 + or - 135.8 vs. 242.0 + or - 80.7g) intakes. Despite high food, protein and energy consumption, PG patients on long term glucocorticoid therapy had lower body muscle mass than controls, while showing high body fat stores. These findings are possibly related to combined metabolic effects of long term corticotherapy and inflammatory disease plus corticosteroid-induced increased appetite
