RESUMO
In a 63-year old male patient coccygodynia, initially isolated then complicated by incomplete cauda equina syndrome, could be attributed to large perineurel meningeal cysts on the sacral nerve roots. The diagnosis was suspected at computerized tomography and nuclear magnetic resonance and confirmed by sacculoradiculography. Intradural injections of corticosteroids provided lasting pain relief. Arachnoid cysts are often asymptomatic, by they may be responsible for coccygodynia and/or incomplete cauda equina syndrome. Their presence is suggested by the characteristics of the symptoms which are paroxysmal, exacerbated in standing position, relieved in dorsal position and revived by percussing the sacrum. Treatment is medical in most cases. The decision to operate depends on the persistence and intensity of pain and on whether signs of neurological defecit are present.

The choice of an optimal contraceptive method (OC) therapy is a significant problem in female SLE patients. In view of the influence of sex hormones on the evolution of SLE, oral contraceptive (OC) therapy has to be efficient, reversible and safe, without aggravating disease activity and causing metabolic and vascular side effects. Ethinyl estradiol-containing preparations, even at 30 micrograms/day, have been shown to trigger a crisis or unmask SLE, and they exert adverse metabolic and vascular effects. Therefore, combination estrogen-progestogen compounds must be avoided in women with SLE. Pure progestogen OC preparations do not stimulate SLE activity, but norsteroids have harmful metabolic effects and microprogestogens are not sufficiently reliable. In light of the decreased level of plasma androgens in female SLE patients, an attempt to modulate the hormonal milieu by lowering the estrogen to androgen ratio, while ensuring contraception was attempted using cyproterone acetate. This agent markedly lowered plasma estrogens and was effective and well tolerated, but its long-term effect on bone mineralization remains to be evaluated. Chlormadinone acetate, a 17-OH progesterone derivative, was proven effective and devoid of any metabolic or vascular side effects, and should be recommended as the safest routine OC therapy in women with SLE.

In patients with interstitial granulomatous sarcoid nephritis, renal failure often suggests the diagnosis, being rapidly progressive and isolated, i.e. without proteinuria and with few abnormalities of the urinary sediment. The extra-renal signs are usually discreet or absent, and the finding of a paradoxically high or normal calcaemia concomitant with renal failure should alert the clinician. When granulomatous lesions of the kidney are not too old, corticosteroids are remarkably effective in improving renal function.
