- Endometriosis-induced intussusception of the caecal appendixPublication . Costa, M; Bento, A; Batista, H; Oliveira, FAppendicular intussusception is an uncommon entity, with a reported incidence of 0.01%. The diagnosis is difficult and often only performed at the time of surgery. Intussusception has multiple causes including tumours, foreign bodies and polyps. The definitive treatment is surgical, and the extent of resection is determined by the underlying pathology and degree of invagination. Endometriosis is a rare cause of appendicular intussusception, with 194 cases described in the English literature. We report a case of a 42-year-old woman who presented with chronic abdominal pain in the lower right quadrant. A mass at the caecum was identified during investigations for renal stones by CT. Colonoscopy showed a polypoid lesion, with presumed origin in the appendix. Ileocaecal resection was performed because an appendicular tumour was suspected. Pathological examination identified endometriosis of the appendix and associated peritoneum with invagination of the caecum. The patient was discharged 7 days after surgery and is currently asymptomatic.

- Hipercortisolismo Recorrente: Após Remoção de Adenoma Hipofisário Secretor de ACTH Associado a Macronódulo da Glândula Supra-RenalPublication . Santos, J; Paiva, I; Gomes, L; Batista, C; Geraldes, E; Rito, M; Velez, A; Oliveira, F; Carvalheiro, MA 29 years old patient was sent to our Outpatient Clinic of Endocrinology presenting clinic of hypercortisolism. Laboratorial study: High urinary free cortisol (UFC); serum cortisol - 25 microg/dl (8 am) (5-25) and 20 microg/dL (11pm); ACTH - 20 pg/mL (9-52) (8 am) and 14 pg/mL (11 pm); serum cortisol after dexamethasone suppression test: 14,9 mg/dL; CRH test: elevation of ACTH; Pituitary MRI: microadenoma; abdominal CT: nodule on the left adrenal. During inferior petrosal sinus sampling with CRH stimulation, ACTH reached 368 pg/mL on the right and 136 pg/mL on the left side. The patient was submitted to transsphenoidal surgery. After surgery, hypertension and physical stigmata improved. In 2006, a relapse of Cushing syndrome was suspected due to worsening of hypertension and increase of weight. A slight increase of UFC, undetectable ACTH and serum cortisol after dexamethasone suppression test equal to 16 microg/dL were found. On abdominal CT, the adrenal nodule kept the same characteristics. In December 2006, the patient was submitted to left adrenalectomy. After surgery, blood pressure normalized, UFC and serum cortisol were reduced, needing substitutive therapy. Progressive tapering of hydrocortisone doses lead to discontinuation in March 2007. He is clinically well, without any treatment. This is an unusual case, in which after surgical cure of Cushing disease, secretory autonomy of a coexisting adrenal nodule occurred. This clinical case is relevant, pointing out the complexity of hypercortisolism cases and the need of long follow-up.
