Calciphylaxis in a patient affected by rheumatoid arthritis, chronic renal failure, and hyperparathyroidism: a case report.

Calciphylaxis, or calcific uremic arteriolopathy, is the tissue and vascular calcification that occurs mainly in chronic kidney disease. However, it can be secondary to parathyroid dysfunction and it has been described in rheumatic patients. We present a case of calciphylaxis in a woman with inactive rheumatoid arthritis, acute renal failure, and hyperparathyroidism.

Hemangioma of the tympanic membrane: a case and a review of the literature.

Hemangiomas of the external auditory canal, involving the posterior bony canal and the adjacent tympanic membrane, although rare, are considered a specific disease entity of the human external auditory canal. Hemangiomas of the tympanic membrane and/or external auditory canal are rare entities; there are 16 previous case reports in the literature. It is a benign vascular tumor. It generally occurs in males in the sixth decade of life. Total surgical excision with or without tympanic membrane grafting appears to be effective in the removal of this benign neoplasm. The authors present a case and a review of the literature discussing diagnostic and surgical approaches.

Ghrelin expression in gut endocrine growths.

We aimed to assess the occurrence of ghrelin, a new gut hormone, in endocrine growths of the stomach. In addition, since ghrelin has been detected in other gut derivatives during adult and/or fetal life, we also studied endocrine tumours of the pancreas, intestine and lung. A specific serum generated against amino acids 13-28 of ghrelin was tested on 16 specimens of gastric mucosa with endocrine cell hyperplasia and on 75 endocrine tumours. Ghrelin-immunoreactive cells were moderately represented in normal, atrophic or hypertrophic gastric mucosa, as a rule with no obvious hyperplastic changes even in the presence of concurrent, prominent enterochromaffin-like cell hyperplasia associated with hypergastrinemia. Ghrelin cells were also found in tumour cell fractions of well-differentiated gastric (25 of 33, 76%), pancreatic (6 of 15, 40%) and pulmonary (4 of 8) endocrine tumours. No ghrelin immunoreactivity was detected in 14 intestinal tumours and in five poorly differentiated endocrine carcinomas of the stomach or pancreas. We conclude that ghrelin cells may take part in gut endocrine growths, with special reference to well-differentiated endocrine tumours of the stomach, independently from associated signs of endocrine hyperfunction.
