Endogenous hyperinsulinemic hypoglycemia syndrome: surgical treatment.

Background: The endogenous hyperinsulinemic hypoglicemia syndrome (EHHS) can be caused by an insulinoma, or less frequently, by nesidioblastosis in the pediatric population, also known as non insulinoma pancreatic hypoglycemic syndrome (NIPHS) in adults. The aim of this paper is to show the strategy for the surgical treatment of ehhs.

Material And Methods: A total of 19 patients with a final diagnosis of insulinoma or NIPHS who were treated surgically from january 2007 until june 2012 were included.

Treatment of postoperative chylothorax through laparoscopic thoracic duct ligation.

We report the laparoscopic transhiatal thoracic duct ligation to solve postoperative chylothorax after right total pleurectomy for malignant diffuse mesothelioma.

[A new methodology for the preoperative localization of occult insulinomas].

Unlabelled: In patients with hypoglycemic syndrome, preoperative localization of the insulinoma highly contributes to surgical removal. When the ultrasonography, computed tomography, magnetic resonance and pancreatic angiography fail to visualize the tumor, they are called occult insulinomas (OI). In this paper we describe the results of a new diagnostic method to localize OI, performed in 5 patients with hypoglycemic syndrome secondary to endogenous hyperinsulinism.

[Gastric carcinoid polyp and type A atrophic gastritis].

Three cases of gastric carcinoid polypi associated to atrophic gastritis and high levels of seric gastrin, are presented. One of the cases was a multiple micropolyposis the literature regarding this association is reviewed and the therapy discussed. Tumors of greater than 2 cm have to be considered potentially malignant and be treated likewise.

Adenylic nucleotides and energy charge during the embryonic development of Bufo arenarum.

The contents of ATP, ADP and AMP were determined by HPLC and adenylic energy charge (AEC) was estimated during different stages of the embryonic development of Bufo arenarum up to the tailbud stage. All the developmental stages studied showed a high ATP content (about 1.04-1.
