Peritoneal pseudomyxoma associated with synchronic malignant mucinous neoplasias of the cecum, appendix and rectum. Case report and review of the literature1 Pseudomixoma peritoneal associado a neoplasias malignas mucinosas do ceco, apêndice e reto. Relato de caso e revisão da literatura

Peritoneal pseudomyxoma is a pathological condition that compromises the peritoneum, characterized by the production of large quantities of mucinous liquid, which progressively fills the peritoneal cavity, originating in general from mucinous appendicular or ovarian tumors.

The urinary obstruction must be immediately relieved in order to avoid deterioration in these patients. The percutaneous nephrostomy is a safe and effective method for relief the obstruction; however the indications of such procedures have been questioned in patients wi...

Aspectos Genéticos do Hipotireoidismo Congênito

Genetic Aspects in Congenital Hypothyrodism. Congenital hypothyroidism (CH) affects between 1:3,000 and 1:4,000 newborns. Many genes are essential for normal development of the hypothalamus-pituitary-thyroid axis and hormone production, and are associated with CH. About 85% of primary hypothyroidism is called thyroid digenesis and evidence suggests that mutations in transcription factors (TTF2,...

Neoplasias of the colorectal crypts.

Colorectal cancers are often preceded by noninvasive neoplasias arising in the surface epithelium, namely tubular, tubulovillous and villous adenomas. That neoplasias may also arise in the colorectal crypts is less well known. Between 1998 and 2002, colonoscopies, rectoscopies and colorectal surgical specimens from 8647 patients were received at this Department for histological diagnosis. The m...
