Basaloid carcinoma of the pancreas--clinicopathological presentation and oncogenetic snapshot of a rare entity.

We report a case of basaloid pancreatic carcinoma with clinical, pathological, and genomic data. The 73-year-old male patient had jaundice, acholic stool, diarrhea, weight loss, and a large, painless gall bladder. His GGT was highly elevated.

[A case of glucose-sensitive insulinoma accompanied by slightly elevated serum insulin levels and persisting convulsions after the surgically removed neuroendocrine tumor].

Insul(in)oma is a usually solitary or, in some cases, multifocal tumor of pancreatic beta cells. It may be a component of multiple endocrine neoplasia type 1. or von Hippel-Lindau syndrome.

Impact of positive intraabdominal lavage cytology on the long-term prognosis of colorectal cancer patients.

Background: Our aim was to investigate the presence of free cancer cells found in lavage cytology specimens taken from the proximity of tumors during the course of curative open and laparoscopic colorectal resections and then examine and compare the long-term disease outcomes in cases of negative and positive cytology. Based on the results, we were hoping to identify the place of peritumoral lavage cytology among prognostic factors for disease recurrence.

Methods: Between January 1, 2005 and December 31, 2007 intraoperative peritoneal lavage cytology was performed in 145 patients who underwent curative colorectal procedures.

Low resonance frequency vibration affects strength of paretic and non-paretic leg differently in patients with stroke.

The objective of the study was to investigate the chronic effect of low frequency whole body vibration (WBV) on isometric and eccentric strength of knee extensors with different force exertion capacity. It was hypothesized that (1) four-week WBV intervention with the low frequency domain would enhance muscle strength and (2) the improvement would be more pronounced in the weaker muscle. To test our hypothesis twenty patients with acute stroke were recruited.

One session of whole body vibration increases voluntary muscle strength transiently in patients with stroke.

Objective: To determine the effect of whole body vibration on isometric and eccentric torque and electromyography (EMG) variables of knee extensors on the affected side of stroke patients.

Design: A randomized controlled study.

Setting: A rehabilitation centre.

Functional evaluation of multidrug resistance transporter activity in surgical samples of solid tumors.

Determination of multidrug resistance (MDR) activity of tumor cells could provide important information for the personalized therapy of cancer patients. The functional calcein assay (MultiDrug Quant Assay, Solvo Biotechnology, Budaörs, Hungary) has been proven to be clinically valuable in hematological malignancies by determining the transporter activity of MDR protein 1 (MDR1, ATP-binding cassette protein [ABC] B1, P-glycoprotein-170) and MDR-related protein 1 (MRP1, ABCC1). In this study, we evaluated if the same functional test was adaptable for the analysis of MDR activity in solid tumors.

Quality of life and patient satisfaction after laparoscopic antireflux surgery using the QOLARS questionnaire.

Background: Currently, evaluation of patient satisfaction and quality-of-life data to estimate the outcome of laparoscopic antireflux surgery is an important issue. This study aimed first to report the midterm results for the surgical management of gastroesophageal reflux disease (GERD) by laparoscopic fundoplication and to evaluate surgical outcome, including quality of life and patient satisfaction. The second aim was to determine whether preoperative quality-of-life measurement can predict which patients will be satisfied with antireflux surgery.

Hypercalcitoninemia in a patient with a recurrent goitre and insulinoma: a case report.

Serum calcitonin has become a very sensitive and specific marker for medullary thyroid carcinoma that should be determined in patients with nodular thyroid disease. However, a few earlier reports indicated that tumors other than medullary thyroid carcinoma including insulinomas arising from pancreatic islet cells may also produce calcitonin. Of the few cases of calcitonin-producing insulinomas previously reported, most had incomplete data or lack of documentation of the association between raised serum calcitonin concentration and immunohistochemical detection of calcitonin in pancreatic islet cell tumors.

[Pancreas pseudocyst or metastasis?].

The authors review a case of a 24-year-old male patient hospitalised for repeated acute abdominal symptoms. His medical history included no diseases worth of mentioning. By imaging techniques (abdominal US and CT scan) a cystic lesion, measuring 40 x 35 x 30 mm in diameter was found, and was diagnosed as pseudocyst in the region of the tail of the pancreas.

[Development and validation of a modified quality of life questionnaire for patients treated by antireflux surgery].

Introduction: Past decade witnessed a growing interest in scientific medical publications on health related quality of life (HRQoL), which has yielded an increasing number of generic and disease-specific instruments. To date, several studies have evaluated the impact of GERD on HRQoL.

Aims: To develop a QoL questionnaire for patients with GERD underwent laparoscopic fundoplication (LF).

Psychometric documentation of a quality-of-life questionnaire for patients undergoing antireflux surgery (QOLARS).

Background: The purpose of our study was to develop a quality-of-life (QoL) questionnaire for patients with gastroesophageal reflux disease (GERD) who have undergone laparoscopic fundoplication. This questionnaire was developed to be more comprehensive than existing measures.

Methods: Between 1994 and 2002, 252 patients underwent laparoscopic fundoplication for GERD in the 1st Department of Surgery, Semmelweis University.

ATP and ATPase secretion by exocrine pancreas in rat, guinea pig, and human.

ATP is an extracellular regulator in numerous physiological and pathologic processes. Recently, 7 different subtypes of purinoceptors were identified on either the basolateral or the luminal membrane of pancreatic duct cells. However, the in vivo regulatory role of ATP in pancreatic function has not been established.

[The first clinical experiences in Hungary with a new effective antibiotic (linezolid) effective against Gram-positive infections].

Introduction: The occurrence of gram-positive infections caused by multiresistant organisms has increased significantly in general, particularly among the surgical patients, and only a few effective antibiotics are available. A new and effective, synthetic antibiotic, against gram-positives is the oxazolidinon group, that electively inhibits bacterial protein synthesis in the early phase. Linezolid, the first member of this group to be used in clinical practice is the linezolid was studied.

Streptococcus pneumoniae as an etiologic agent in infectious complications of pancreatic disease.

Systematic culturing of perioperative intra-abdominal samples allowed us to recognize the presence of Streptococcus pneumoniae in infectious complications of chronic pancreatitis in 9 male patients. In 8 of 10 of the intra- or peripancreatic samples, S. pneumoniae was the single isolate identified.

Pancreatic head mass: how can we treat it? Tumor: surgical treatment.

Pancreatic carcinoma is a devastating disease. Untreated 5-year survival is 0%. The only possibility of being cured is given by surgical removal of the tumor.

Pancreatic head mass: what can be done? Diagnosis: computed tomography scan.

The diagnosis of different pancreatic diseases has recently become a recurrent problem. In cases with pancreatic head mass the main question is the differentiation between malignant and benign lesions. When a neoplasm is suspected, the main task is to judge operability.

Pancreatic head mass: what can be done? Classification: the clinical point of view.

Surgeons frequently find pancreatic head mass when operating. The obvious difficulty is to make the correct preoperative differential diagnosis between chronic pancreatitis and pancreatic tumor. The first step is to reach a diagnosis, with some certainty, prior to the operation.

Adhesion molecules in human pancreatic cancer.

Background And Objectives: Adhesion molecules are cell surface glycoproteins that are important in cell-to-cell and cell-to-extracellular matrix interactions. In the present study, we analyzed the adhesion molecules ICAM-1 (intercellular adhesion molecule-1), VCAM-1 (vascular cell adhesion molecule-1), and ELAM-1 (endothelial leukocyte adhesion molecule-1) in human pancreatic cancer.

Methods: ICAM-1, VCAM-1, and ELAM-1 were analyzed in 20 pancreatic cancer specimens and 20 normal pancreatic tissues.

Influence of resection margins on survival for patients with pancreatic cancer treated by adjuvant chemoradiation and/or chemotherapy in the ESPAC-1 randomized controlled trial.

Objective: To assess the influence of resection margins on survival for patients with resected pancreatic cancer treated within the context of the adjuvant European Study Group for Pancreatic Cancer-1 (ESPAC-1) study.

Summary Background Data: Pancreatic cancer is associated with a poor long-term survival rate of only 10% to 15% after resection. Patients with positive microscopic resection margins (R1) have a worse survival, but it is not known how they fare in adjuvant studies.

The laparoscopic treatment of non-parasitic liver cysts. Five years experience.

The incidence of cystic liver lesions seems to be more frequent as previously suggested. The treatment of symptomatic non-parasitic cysts is controversial. Ultrasonography (US) or computer tomography (CT) guided drainage and/or sclerotization versus surgical fenestration or partial resection, even liver resection has been advocated.

Laparoscopic adrenalectomy. New experiences.

Authors have performed 23 laparoscopic adrenalectomies between 03.04.1997 and 02.

Development of a disease specific quality of life (QoL) questionnaire module to supplement the EORTC core cancer QoL questionnaire, the QLQ-C30 in patients with pancreatic cancer. EORTC Study Group on Quality of Life.

There is overwhelming consensus that quality of life assessment is urgently required in pancreatic cancer, yet little research has been conducted. We report on the development of a disease specific questionnaire module to supplement the EORTC core cancer module, the QLQ-C30 in patients with pancreatic cancer, using EORTC quality of life study group guidelines for module development. Relevant QoL issues were generated from literature searches and interviews with health professionals and patients with pancreatic cancer.

Technical aspects of left-sided pancreatic resection for cancer.

Adenocarcinoma of the pancreas that originates to the left of the portal vein, i.e. in the body or tail of the pancreas, is seen in approximately one third of all cases with exocrine pancreatic cancer.
