Colloid carcinoma of the pancreas: a distinct pancreatic neoplasm with good prognosis. Report of a case.

Context: Colloid carcinoma is considered a distinct type of pancreatic neoplasia with specific histopathological and molecular features, and a better prognosis.

Case Report: We present the case of a patient with a 15 cm locally invasive colloid carcinoma of the pancreas, in which an aggressive surgical approach achieved no evidence of disease 24 months after surgery.

Conclusions: If an accurate diagnostic approach and surgical resection are performed, the 5-year survival rate can reach 60%.

[Thyroid suppression in patients with primary hyperparathyroidism: does it improve the pre-surgical scintigraphy localisation?].

Introduction: Scintigraphy with technetium-sestamibi (MIBI) is the test of choice for localising adenomas in patients with primary hyperparathyroidism (PHPT). In some studies it has emerged that the increase in sensitivity of this test could be associated with a decrease in the uptake of the radiotracer by the thyroid gland. The aim of this study is to analyse our experience in patients with a negative scintigraphy with MIBI, and in whom the study was repeated after suppression of thyroid function with thyroxine.

[Influence of pre-surgical chemotherapy on liver parenchyma and post-surgical outcome of patients subjected to hepatectomy due to colorectal carcinoma metastases].

Introduction: The aim of the study was to evaluate the relationship between the pre-surgical administration of a chemotherapy regime based on irinotecan or oxaliplatin and the development of non-alcoholic fatty liver disease (NAFLD) or sinusoidal obstruction syndrome (SOS), and the influence of these histological changes on the outcome of patients after surgical intervention.

Patients And Method: A prospective study which included 45 patients surgically intervened due to colorectal cancer liver metastases between May 2005 and July 2009. Demographic data and the variables before during and after the operation were collected.

Cystic lymphangioma of the lesser omentum in an adult.

Abdominal lymphangiomas are uncommon congenital benign tumors that occur mainly in children. The authors report the case of a 37-year-old woman with a cystic lymphangioma of the lesser omentum. The lesion was removed surgically with a complete resection.

[Surgical treatment and localization techniques in primary hyperparathyroidism].

Parathyroidectomy is the only definitive cure for primary hyperparathyroidism (PHPT). While bilateral neck exploration has been the conventional surgical approach and the mainstay of therapy, recent advances in technology have revolutionized the field, making a focused or minimally invasive approach to parathyroidectomy a reality. This change has taken place because of the development of accurate preoperative localization techniques able to select patients who have single-gland parathyroid disease (single adenoma) and can be managed by a minimally invasive parathyroidectomy.

Inducible nitric oxide synthase (iNOS) expression in autoimmune thyroid disorders (AITD).

Introduction: Nitric oxide is synthesized by different cell types through the action of the enzyme nitric oxide synthase (NOS). There are four isoforms of this enzyme: the neuronal, the endothelial, the mitochondrial, and the inducible (iNOS) forms. Although NO production may play an important role in the pathogenesis of inflammation and tissue damage, its possible role in autoimmune thyroiditis has not been adequately explored.

99MTc-sestamibi as sole technique in selection of primary hyperparathyroidism patients for unilateral neck exploration.

Background: Unilateral neck exploration (UNE) is becoming the procedure of choice for treatment of primary hyperparathyroidism (PHPT). The aim of this study was to evaluate the role of (99m)Tc-sestamibi (MIBI) parathyroid scintigraphy as the sole technique in selecting patients for UNE.

Method: We selected 136 consecutive PHPT patients who had only 1 solitary uptake at a MIBI were for UNE.

Prospective study of risk factors for ventilator-associated pneumonia caused by Acinetobacter species.

Unlabelled: The incidence of ventilator-associated pneumonia (VAP) by Acinetobacter spp (VAPA) is increasing and has high morbidity and mortality. It is imperative to identify risk factors to be able to use prevention policies.

Objective: The aim of this study was to identify specific risk factors for VAPA.

[A new surgical technique for thoracic parathyroid glands: video-assisted thoracoscopy with intraoperative Tc-MIBI scintigraphy].

Ectopic mediastinal parathyroid glands are uncommon (1-11% of all cases of hyperparathyroidism). Median sternotomy used to be performed to resect them, with large and painful incisions that prolonged the length of hospital stay. Current imaging techniques (thoracic computed tomography and Tc-mibi scan) can accurately locate the ectopic glands, allowing minimally invasive exploration.
