Surgery in MEN 2A Patients Older Than 5 Years with Micro-MTC: Outcome at Long-term Follow-up.

In multiple endocrine neoplasia syndrome type 2A (MEN 2A), early total thyroidectomy (TT; performed before the age of 5 years) is the best option to prevent medullary thyroid carcinoma (MTC) development, but the management of MEN 2A patients diagnosed after childhood is still under debate. Seventeen consecutive patients diagnosed with MEN 2A after the age of 5 years (mean age, 23.3 years) with a pathologic diagnosis of micro-MTC without nodal involvement were enrolled.

Follicular nodules (THY3) of the thyroid: we recommend surgery.

Objective: To determine the need of total thyrodectomy for patients with follicular nodules of thyroid.

Subjects And Methods: From January 2005 through June 2008, 2249 consecutive patients (438 males, 1811 females; mean age 54 yr, range 9-87) with thyroid nodules were submitted to 2518 ultrasound-guided fine-needle aspiration (USgFNA) for cytological examination. USgFNA were performed by experienced surgeon (RP) and endocrinologist (RGG) under ultra- sonographyc guidance, using a 10-MHz linear transducer.

Gestational diabetes insipidus: a morphological study of the placenta.

Gestational diabetes insipidus (GDI) refers to the state of excessive water intake and hypotonic polyuria. Those cases manifesting in pregnancy and referred to as GDI may persist thereafter or may be a transient latent form that resolves after delivery. Microscopic examination of affected subjects has not been previously reported.

Distributional map of the terminal and sub-terminal sugar residues of the glycoconjugates in the prepubertal and postpubertal testis of a subject affected by complete androgen insensitivity syndrome (Morris's syndrome): lectin histochemical study.

In the present research we have investigated the distribution of the sugar residues of the glycoconjugates in the prepubertal and postpubertal testes of a subject with Morris's syndrome (CAIS, Complete Androgen Insensitivity Syndrome). For this purpose a battery of six horseradish peroxidase-conjugated lectins was used (SBA, PNA, WGA, ConA, LTA and UEAI). We have obtained a complete distributional map of the terminal and sub-terminal oligosaccharides in the tunica albuginea, interstitial tissue, lamina propria of the seminiferous tubules, Leydig cells, Sertoli cells, spermatogonia, mastocytes and endothelial cells.
