[Para- and suprasellar meningioma coincident with a hormonally active intrasellar hypophyseal adenoma--case report].

We observed a 53 year old man, who presented with a progressive impotence, a decrease of libido and a left sided defective vision. A MRI-study detected a left-sided meningioma para- and suprasellar and an intrasellar adenoma of the anterior lobe of pituitary. The pituitary function tests revealed a prolactinoma. Both tumors could be removed via a left-sided frontolateral approach. Histological examination confirmed the diagnosis of an endotheliomatous meningioma and a prolactinoma. The persistence of elevated prolactin serum level gave necessity of dopamine agonist therapy postoperatively. Postoperatively left sided visus improved slightly. The importance of MRI-study is discussed. Nowadays multiplanar MRI is necessary for planing an optimal neurosurgical approach. The literature is reviewed and the coincidence of the two tumors of sellar region is discussed. We believe in an accidental coincidence, even if there are some hints, which may point out a relation in the pathogenesis of meningiomas and adenomas of the adenohypophysis.

[Carpal tunnel syndrome, a late complication in chronic hemodialysis].

145 patients on haemodialysis for 1 month to 16 years were examined for carpal tunnel syndrome. Typical signs and symptoms of the syndrome, mostly in both hands but more pronounced on one side, were seen in 21 patients (15%). In these cases carpal tunnel syndrome was frequently (19%) accompanied by Raynaud's phenomenon of the digits supplied by the median nerve. There was a significant correlation between the incidence of carpal tunnel syndrome and the duration of dialysis. The association of carpal tunnel syndrome with analgesic nephropathy was significantly higher than with other kidney diseases. Immediate relief of pain was achieved after carpal tunnel release in eight patients (11 hands). Sensory and motor function was gradually, but often only partially, restored. Unoperated carpal tunnel syndrome progressed to loss of sensory and motor function within 1 to 4 years after onset of symptoms. Carpal tunnel syndrome should be considered an important late complication of chronic haemodialysis.

Carpal tunnel syndrome: a major complication in long-term hemodialysis patients.

One hundred and forty-five patients on hemodialysis for periods of 1 month to 16 years were examined clinically for carpal tunnel syndrome (CTS). Typical symptoms and clinical manifestations of symptomatic CTS, either unilaterally or in both hands, were detected in 21 of these patients (15%). In contrast to the classic form of CTS, hemodialysis CTS in our patients was frequently accompanied by Raynaud's phenomenon of those digits supplied by the median nerve. A highly significant correlation was established between the incidence of CTS and the duration of dialysis (p less than 0.001). The association of CTS with analgesic nephropathy was significantly higher (52%) than with other kidney diseases (p less than 0.034). Immediate relief of pain was achieved after carpal tunnel release (11 releases) in 8 of the 21 patients. Sensory and motor function was gradually, but often only partially, restored. Unoperated CTS progressed to loss of sensory and motor function within 1 to 4 years after the onset of symptoms. CTS should be considered a major late complication in patients on chronic hemodialysis.

[Discographic visualisation of lumbar disc herniations (author's transl)].

The myelographic diagnosis of lumbar disc herniations remains unclear in about 5% of the cases. When the clinical examination does not allow clear localisation of the segmental level of the lesion and symptomatology is atypical, discorgraphy may be the only procedure providing further diagnostic information. Very lateral as well as ventral disc herniations can thus be clearly demonstrated. Knowledge of both typical and atypical findings is, however, required to avoid false negative results.

[Anterior lumbar disc herniations (author's transl)].

Anterior lumbar disc herniations can easily and clearly be evidented by discography. The morbidity and, especially, the clinical importance of this entity, however, has been described by some authors only. According to our own experience with discography, ventral lumbar disc herniation seems to be correlated with a painful syndrome consisting of both a typical and circumscribed backache and pain radiating into the abdominal cavity and genital area along the lateral aspect of the lumbar region.
