[Intestinal carcinoid. A propos of a case]. / Il carcinoide intestinale. A proposito di un caso.

In this paper the authors report a case of carcinoid neoplasm in a rare localization like sigmoid colon. They describe the clinical and biological aspects of this kind of tumors, with particular regard to the tumor site and its biochemical products. A rational and prompt clinical approach to this neoplasm is considered important for the good chance of long survivals, achievable in the case of early diagnosis.

Heterogeneity of soluble and nuclear oestrogen receptor status of involved nodes in relation to primary breast cancer.

Both soluble and nuclear oestrogen receptors were measured in at least two different portions of primary breast cancer and in concurrent metastatic tissue from axillary nodes. Oestrogen receptor (ER) status of involved nodes was found highly consistent with that of primary tumours. Of the 67 patients studied, 30 had metastatic nodes which contained both soluble and nuclear ER. Of these, 27 were associated with a primary cancer which also had both soluble and nuclear ER, determined in at least two separate parts of the primary cancer. Conversely, none of the completely negative primaries gave rise to fully receptor positive metastatic tissue. Surprisingly, 17 out of 20 heterogeneous primary tumours, i.e. those containing both receptor positive and negative components, generated receptor negative metastatic nodes. Moreover, in 7 of the 8 patients with N-2 stage nodal involvement, the metastatic disease had arisen from primaries which were either completely receptor negative or with a heterogeneous ER status. It is suggested that macroscopic heterogeneity of ER status in primary breast cancer is associated with poor prognosis.

Paraplegia, syringomyelia tarda and neuropathic arthrosis of the shoulder: a triad.

A casually related triad of syringomyelia tarda, postparaplegia with secondary neuropathic arthrosis of the shoulder has been presented. The development of neuropathic arthrosis of the shoulder has been presented. The development of neuropathic arthrosis of the shoulder in 2 of our paraplegic patients prompted us to look for a correlation and/or a common etiology. Paraplegia secondary to spinal cord injury could be causative or at least an associated factor in a delayed proximal syringomyelia. It is the syringomyelia which can lead to the neuropathic arthrosis in the upper extremity, mainly, in the shoulder. There is an interesting pathological association of paraplegia and syringomyelia with neuropathic arthrosis. Earlier awareness of any neurological changes in the upper extremity of the paraplegic patient could point to recognition of syringomyelic process and portend a tendency toward neuropathic arthrosis of the shoulder. This would require a high index of suspicion, and subsequently a preventative, protective orthopedic approach to minimize the usual functional deformity that occurs when this neuropathy involves the shoulder.
