Prognostic Significance of Two Dimensional AgNOR Evaluation in Local Advanced Rectal Cancer Treated with Chemoradiotherapy.

The prognostic significance of AgNOR proteins in stage II-III rectal cancers treated with chemoradiotherapy was evaluated. Silver staining was applied to the 3μm sections of parafin blocked tissues from 30 rectal cancer patients who received 5-FU based chemoradiotherapy from May 2003 to June 2006. The microscopic displays of the cells were transferred into the computer via a video camera.

[Lipoid proteinosis (Urbach-Wiethe's Disease)].

A 25-year-old female patient was admitted to our outpatient clinic with postpartum hoarseness. Punch biopsy specimens obtained from the larynx and sublingual region revealed multi-folded squamous epithelium with a hyperkeratosis pattern and amorphous hyaline material aggregation. This aggregation was also remarkable around the vessels.

Is Every Patient Followed up as a Papillary Thyroid Cancer Patient Really That?

Unlabelled: We report the case of a 64-year-old man followed up for two years as suffering from differentiated thyroid cancer (DTC). In the patient's follow up, despite thyroglobulin level and I-131 whole body scan results being normal, metastases were identified at the 4th thoracic vertebra corpus by MR. Histopathological findings were carcinoma metastases.

Prognostic value of NF-κB, CD9, and VEGF in gastrointestinal stromal tumors.

Aim Of The Study: Gastrointestinal stromal tumors (GISTs) are the most frequent mesenchymal tumors of the gastrointestinal system. We aimed to determine whether nuclear transcription factor κB (NF-κB), CD9 and vascular endothelial growth factor (VEGF) have prognostic value in patients with GIST.

Material And Methods: Thirty-five patients with GIST, who were diagnosed in the Pathology Department of Erciyes University, were included in the study.

A huge solitary fibrous tumor localized in the pancreas: a young women.

Context: Solitary fibrous tumor is an uncommon spindle cell tumor which were first described in 1931 at pleura; it should be seen rarely in extra-pleural localization.

Case Report: We report the ninth case of pancreatic solitary fibrous tumor in a 24-year-old woman who presented with mild epigastric pain radiating to the back and chronic constipation. Imaging studies confirmed a solitary mass in the epigastric region that begins from posterior of stomach, fills little curvature and extends to pelvis, invades vascular structures by encircling them and extends to retroperitoneal regions that was considered as it may have mesenchymal origin.

Cyclooxygenase-2 expression in gastrointestinal stromal tumours.

Background: While it is well known that cyclooxygenase-2 (COX-2) expression is increased in colorectal adenoma and carcinoma, there is only limited information on its status in stromal tumours.

Methods: Immunohistochemical COX-2 staining was performed on a total of 42 confirmed gastrointestinal stromal tumours (GISTs) in the Pathology Department of Gaziantep University and the findings were compared with various other parameters.

Results: We found a statistically significant correlation between the tumor mitosis and COX-2 expression in GISTs.

Prognostic significance of CD9 expression in locally advanced gastric cancer treated with surgery and adjuvant chemoradiotherapy.

The tetraspanin transmembrane protein CD9 plays an important role in inhibiting cell motility in numerous neoplastic cell lines, including lung, gastric, pancreatic, and bladder carcinomas. The prognostic importance of CD9 in the survival of gastric carcinoma patients has not been examined to date, and in the present study, we attempted to define its prognostic value. The study included 49 (35 men and 14 women) patients with locally advanced (stages II-IV) gastric cancer.

Which urine marker test provides more diagnostic value in conjunction with standard cytology- ImmunoCyt/uCyt+ or Cytokeratin 20 expression.

Background: Because of the poor sensitivity of urinary cytological findings for the diagnosis of especially low grade urinary bladder carcinoma, new molecular diagnostic methods have been proposed. We decided to verify the ImmunoCyt/uCyt+ (UCyt+) test and cytology combination and cytokeratin 20 (CK20) and cytology combination in urine as possible diagnostic and monitoring tool for bladder cancer.

Methods: Evaluation of CK20 expression and UCyt+ was performed in urine of 90 patients of which 54 with bladder cancer with primary/recurrent diagnosis (low grade urothelial carcinoma (LGUC) = 23/8 patients, high grade urothelial carcinoma (HGUC) = 18/5 patients), and 36 patients as control; except of neoplastic bladder disease patients.

Radiological findings of isolated hepatic tuberculosis in a child with tubulointerstitial nephritis-uveitis syndrome.

Isolated hepatic tuberculosis is a rare manifestation of tuberculosis in children although its incidence has been increasing, especially in immunosuppressed patients. Imaging studies frequently present a diagnostic challenge, especially for the nodular form. Thus a high index of suspicion is required for diagnosis.

Different seizure types and skin lesions in oculocerebrorenal syndrome of Lowe.

Oculocerebrorenal syndrome of Lowe is an X-linked recessive disorder localized to Xq24-26.1. The phenotypic features of this disorder are Fanconi-type renal failure, mental retardation, and various eye abnormalities.

Effect of interleukin-10 on tissue damage caused by organophosphate poisoning.

Organophosphate poisoning is a common cause of severe morbidity and mortality among patients admitted to emergency departments. Tissue damages as a consequence of organophosphate poisoning are frequently reported, but preventing this potentially severe complication has not been the subject of much research. We tested whether interleukin-10, a cytoprotective agent, could prevent or diminish pathological signs of tissue damages caused by organophosphate poisoning.

Hepatic von Meyenburg complex simulating biliary cystadenocarcinoma.

Multiple bile duct hamartomas [von Meyenburg complex (VMC)] are benign liver malformations that include biliary cystic lesions, with congenital hepatic fibrosis being the cause of ductal plate malformations. This rare entity is usually isolated and detected incidentally in 0.6-5.

Inferior vena cava obstruction due to cecum adenocarcinoma.

In this paper, we report the radiologic findings of cecal adenocarcinoma with caval invasion in a 60-year-old man. Caval invasion was confirmed by ultrasonographically guided fine-needle aspiration biopsy and by surgery. To our knowledge, this is the first case report demonstrating malignant caval thrombus due to colon cancer.

MR cholangiopancreatography findings of heterotopic pancreatic tissue in the distal common bile duct.

Heterotopic pancreas is defined as the presence of pancreatic tissue at sites other than the pancreas. Involved sites may be the stomach, duodenum, proximal jejunum, ileum, congenital duodenal web, Meckel's diverticulum, ampulla of Vater, and the main pancreatic duct. We report the magnetic resonance cholangiopancreatography findings of a patient who had biliary obstruction due to heterotopic pancreas tissue at the distal common bile duct.

Acute lymphoblastic leukemia associated with brucellosis in two patients with fever and pancytopenia.

Brucellosis is a disease involving the lymphoproliferative system, which may lead to changes in the hematological parameters; however, pancytopenia is a rare finding. However, malignant diseases in association with brucellosis are rarely the cause of pancytopenia. Herein, two cases with fever and pancytopenia, diagnosed as simultaneous acute lymphoblastic leukemia and brucellosis are presented.

Single dose of anti-transforming growth factor-beta1 monoclonal antibody enhances liver regeneration after partial hepatectomy in biliary-obstructed rats.

Background: Transforming growth factor (TGF) beta is a potent inhibitor of hepatocyte DNA synthesis and liver regeneration. TGF-beta(1) expression progressively increases in obstructive jaundice. We investigated the effect of TGF-beta(1) blockage on liver regeneration in rats induced with obstructive jaundice.

The value of fine needle aspiration biopsy in the diagnosis of metastatic liver tumours.

Background/aims: Fine needle aspiration biopsy is a useful tool in the diagnosis of primary malignancies and metastatic lesions of the liver. The aim of this study was to determine the types and features of tumors diagnosed by this method and the difficulties in differential diagnosis.

Methods: Fine needle aspiration biopsy smears from 704 patients with metastatic liver lesions were reviewed.

Experimental posterior perforating ocular injury in rabbit eyes: effects of radiotherapy with or without intravitreal cyclosporin on vitreous proliferation.

Double perforating ocular injuries were made in 30 rabbits and the effects of radiotherapy (RT) alone or in combination with cyclosporin (CS) on vitreous proliferation investigated. Thirteen rabbits in group 1 received RT alone (600 cGy), and 13 rabbits in group 2 received RT combined with 100 microg of intravitreal CS. No treatment was given to 4 rabbits in the control group (group 3).

An uncommon lesion: gastric xanthelasma.

Although the clinical significance of gastric xanthelasmas is unclear, they are important lesions because they may be confused with malignant lesions. The etiopathogenesis is also unclear, but chronic gastritis, Helicobacter pylori (H. pylori) infection, diabetes mellitus and hyperlipidemia have been implicated.

Importance of anticoagulant proteins in chronic liver diseases.

Background/aims: This study was conducted to elucidate the importance of anticoagulant proteins in chronic liver disease and their possible role as markers in determining the severity of the liver disease.

Methods: This study was conducted on 35 patients with cirrhosis, 15 patients with chronic active hepatitis and 10 healthy controls. Coagulation inhibitor proteins such as protein C, protein S and antithrombin, as well as D-dimer level and thrombin time, which reflect fibrin degradation products, were measured.

Ergothioneine pretreatment protects the liver from ischemia-reperfusion injury caused by increasing hepatic heat shock protein 70.

Background: Reperfusion of the liver after ischemia induces the expression of the heat shock genes and the synthesis of the heat shock proteins (HSP). We studied the effects of the natural antioxidant ergothioneine (EGT) treatment on the expression of HSP70 in ischemic-reperfused (IR) liver.

Methods: Adult male Wistar rats were randomly divided into three groups: Sham group given standard laboratory chow and water for 3 weeks followed by sham operation; Control group given standard laboratory chow and water for 3 weeks followed by liver IR injury; EGT group given standard laboratory chow supplementation l-ergothioneine (1.

Prostatic adenocarcinoma metastasis in the thyroid gland.

Metastasis from prostate to thyroid gland is very uncommon. Here we report a 77-year-old man who was admitted to the hospital because of a nodular goiter. A fine-needle aspiration biopsy of the nodule showed metastatic prostatic adenocarcinoma.

Xanthogranulomatous orchitis with scrotal fistulas.

Xanthogranulomatous orchitis is an extremely rare inflammatory change of testis which is difficult to distinguish from testicular tumor. We report on a 21-year-old man who presented with left testicular swelling and pyogenic discharge from the scrotum. Testicular tumor markers were normal.
