Abstract
The authors present a case of tumoral calcinosis (TC) in a patient with chronic renal insufficiency. The clinical course, imaging features and microscopic findings are detailed. A 60-year-old woman with a 4-year history of hemodialysis presented with a painful mass in the right posterior cervical triangle. The neuroimaging revealed polycystic mass bulging from the C3-C5 facet joints and lamina on the right. The majority of cystic mass was excised and microscopic features of the specimen were consistent with TC. Tumoral calcinosis is a rare disease characterized by calcium salt deposits in periarticular soft tissue, which enlarge to form tumor-like cystic masses containing chalky calcareous material. TC is typically seen around large joints but rarely in the spine. Review of past publications provided six cases of TC involving the spine in dialyzed patients.

Abstract
BACKGROUND Anastomotic dehiscence and leaks are major problems in gastrointestinal surgery and result in increased morbidity and mortality. The ideal device to create anastomoses should ensure good serosal apposition without requiring either transgression of the bowel wall or the presence of foreign material for an extended period of time. OBJECTIVES The aim of this experimental study was to evaluate the safety and efficacy of a new compression anastomosis clip (CAC) for jejunojejunostomies and ileocolostomies by comparing CAC anastomoses with hand-sewn (HS) anastomoses in pigs in terms of healing, breaking strength and the time to create anastomoses. MATERIAL AND METHODS The 11 pigs in the study underwent side-to-side CAC and HS jejunojejunostomies and ileocolostomies, for a total of 88 anastomoses. The pigs were sacrificed on postoperative day 5 (5 pigs) or 7 (6 pigs). Macroscopic, histopathological and breaking-strength examinations were performed. The time to create the anastomoses was recorded. RESULTS Neither group had anastomotic complications such as leakage or obstruction. Macroscopic examination showed no statistically significant differences between the groups. In the CAC group, the healing process was characterized by a lesser inflammatory reaction (p < 0.05) and very thin scar tissue at the anastomotic line (less collagen deposition and better epithelial regeneration), while the HS group had a much thicker anastomotic line. The breaking strength was significantly greater in the CAC group compared with the HS group (p < 0.05). The anastomosis time was shorter in the CAC group than in the HS group (p < 0.01). CONCLUSIONS Anastomosis using a CAC appears to be safe and less time-consuming than HS; it was also characterized by a good healing process with little inflammatory reaction and a high breaking strength compared with HS anastomosis.

Abstract
Hypermethylated in cancer 1 (HIC1) is a putative suppressor gene, cooperating with TP53 in the regulation of apoptosis. The promoter site of this gene contains CpG islands susceptible to methylation. Altered methylation leads to the silencing of HIC1. Persistent loss of HIC1 function reflects the attenuation of proapoptotic characteristics of TP53 and may constitute the background for carcinogenesis. Altered methylation profiles along with diminished expression of HIC1 were documented in a number of solid neoplasms. The aim of this study was to evaluate the expression of the HIC1 gene in laryngeal carcinoma. RNA was extracted from samples of laryngeal cancer and corresponding healthy tissues of 21 patients with advanced laryngeal cancer (T3-T4). The amount of RNA (cDNA) was evaluated using reverse transcription-quantitative polymerase chain reaction with GADPH as the reference gene. Data demonstrated that HIC1 expression was significantly reduced in laryngeal cancer tissues. The relative expression of HIC1 was found to be ~40% lower in tumor samples compared to that in healthy controls. The median tumor/normal tissue ratio for HIC1 was 0.615. These results suggest that low HIC1 expression may be associated with neoplastic transformation in the larynx.

Abstract
Background A mass of visceral adipose tissue is one of the most important determinants of progressive liver injury in nonalcoholic fatty liver disease (NAFLD). In accordance, nonalcoholic steatohepatitis (NASH) and fibrosis are believed to occur more commonly in morbidly obese patients compared with nonobese NAFLD patients. Aim of the study Comparative analysis of NAFLD histopathologic features and angiogenesis activity in morbidly obese and nonobese subjects. Materials and methods Biopsy samples from 40 severely obese (BMI ≥40 kg m−2) and 30 nonobese (BMI ≤30 kg m−2) NAFLD patients were examined. Kleiner’s classification was used to diagnose NASH by grading steatosis, cytoplasmatic ballooning of hepatocytes, and lobular inflammation. The severity of fibrosis was evaluated according to the liver fibrosis staging system. Qualitative and quantitative immunohistochemical analyses of VEGF A, Flk-1, and CD34 were performed to study angiogenesis and the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) method was used to study hepatocyte apoptosis. Results Severely obese patients did not differ from nonobese patients with respect to age and sex distribution. NASH was diagnosed in nine (22.5%) severely obese patients and in seven (23.3%) nonobese patients. Fibrosis was more common in morbidly obese patients (82.5 vs. 43.5%, χ² = 11.71, p = 0.003) and was not associated with NASH. Moreover, the severity of fibrosis was greater in obese patients, as advanced fibrosis (bridging fibrosis and cirrhosis) occurred in six (15%) severely obese patients and in two (6.7%) nonobese patients. In morbidly obese individuals, angiogenesis was independent of NASH and was activated at the stage of simple steatosis. In severe obesity, there was a positive relationship between the stage of fibrosis and angiogenic activity. Conclusion In severely obese patients, fibrosis is probably promoted by mechanisms independent of NASH. In these patients, angiogenesis is activated early in the natural history of NAFLD and correlates with the severity of fibrosis.

Abstract
INTRODUCTION It is estimated that between XVI and XIX century one fourth of European population died of tuberculosis. Nowadays tuberculosis is still one of the most important infectious diseases. In 2009 estimately 9 million new cases were registered worldwide, mortality due tuberculosis reached 1.5 million. In Poland extrapulmonary tuberculosis is rare (7% of overall morbidity) and most commonly affects pleura, lymph nodes, bones, joints and genitourinary system. Head and neck tuberculosis is rare and causes many diagnostics problems. METHODS Retrospective analysis of case histories of patients admitted to ENT Department of Silesian Medical University in Katowice. RESULTS Between 1993 and 2010 four cases of head and neck tuberculosis were diagnosed in our Clinic. Two of patients were admitted to the hospital with symptoms of laryngeal tumor such as difficulty in swallowing. During direct laryngoscopy tissue specimens were taken. Examination of the third patient showed tumor located below left angle of mandibule. During superficial parotidectomy tumor was removed. In the fourth registered case tuberculosis manifested as tumor of nasopharynx. In every case which is mentioned above pathology reports revealed epithelioid cell granulomas with caseous necrosis typical for tuberculosis. Patients underwent tuberculostatic treatment. CONCLUSION Rare occurrence and lack of characteristic symptoms of head and neck tuberculosis often lead to misdiagnosis. Histopathological examination is the most important diagnostic procedure. Microbiological examination is difficult in extrapulmonary tuberculosis, because of low concentration of pathogens in specimens. Tuberculostatic therapy is the leading method of treatment in every case of tuberculosis.

Abstract
BACKGROUND Ewing sarcoma is a malignant, small round cell bone tumor, presenting predominantly in children and adolescents. Ewing sarcoma may develop in every bone; diaphyses of long bones, ribs and flat bones are the main locations. Local and systemic clinical symptoms are nonspecific - pain, swelling, fever or ill-being. The aim of the study was to assess the role of radiography, computed tomography and magnetic resonance imaging in the analysis of bone lesions in children and young adults with Ewing sarcoma. MATERIAL/METHODS Twenty-seven patients, aged between 1 year and 10 months, and 17 years and 2 months, with histologically verified Ewing sarcoma of the bone, referred to the Radiological Department of University Hospital No 6., John Paul II Upper Silesian Centre for Child Health Katowice, in the period from 1996 to 2007, were included in the study.Plain radiography was performed in every child, CT in 20 and MRI in 12 individuals. Tumour location, extension of the tumour, soft tissue mass, and periosteal reaction were taken into consideration in the evaluation of the lesion. In some cases, pathological features of the MRI and CT were compared. The prevalence of some radiological features was compared to the literature data. RESULTS THE MOST COMMON SITE OF TUMOR WAS: ribs (6 children), femoral bone (6 children), pelvis (4 children) and tibia (3 children). In 2 children, a primary tumor was diagnosed in the spine (multifocal in 1 child). X-rays revealed: periosteal reaction in 17 children (63%), soft tissue involvement in 19 children (70%), permeative component in 16 children (59%), and sclerotic component in 5 children (19%). In 10 children (37%), periosteal reaction was not detected. The examination revealed: soft tissue calcifications in 7 cases (26%), a well-delineated focus of destruction within bones in 3 children (11%), cortical thickening in 4 children (15%), cortical destruction in 4 children (15%), saucerisation in 3 children (11%), bone expansion in 3 children (11%), pathological fracture in 2 children (7%), cystic component in 1 child (4%), and vertebra plana in 1 child (4%).Reaction of tumors after i.v. contrast administration, shown on CT, was visible in 16 children - it was useful for a better description of the tumor and extension of the mass within the soft tissue. All MRI examinations (12 children) showed a heterogenous mass with ill-defined borders and a violated cortex. Low signal intensity of the tumor in a T1-weighted image and high signal intensity in a T2-weighted image was shown as well. Heterogenous enhancement of signal intensity on T1-weighted images could be observed after i.v. contrast administration. MRI EXAMINATIONS SHOWED: tumor in an adjacent soft tissue in 11 children, and involvement of the epiphyseal plate or of the joint cavity in 6 children. CONCLUSIONS X-ray and MRI are essential in diagnostics. CT examination is more useful to estimate periosteal reactions and destruction of bone and marrow cavity, especially in flat bones. However, to recognise a malignancy, it is necessary to perform a histopathological examination. In doubtful cases, the examination has to be verified as well.

Abstract
BACKGROUND Visfatin has been identified as a new adipokine with proinflammatory and immunomodulating properties. It seems to interfere with immune and fibrogenic process in nonalcoholic fatty liver disease (NAFLD). The aim was to assess visfatin expression in the liver tissue and its association with biochemical parameters and morphological features in NAFLD patients. MATERIAL AND METHODS The study included 40 severely obese patients with NAFLD who underwent intraoperative wedge liver biopsy during a bariatric operation. Immunohistochemical assay was carried out with the use of a visfatin mice monoclonal antibody. RESULTS Visfatin expression in the liver was observed in all patients. The expression was significantly higher in patients with fibrosis (p = 0.036) and was positively correlated with the fibrosis stage (r = 0.52, p = 0.03). There was no difference between patient with nonalcoholic steatohepatitis (NASH) and simple steatosis (p = 0.54). Inflammatory activity and NAS (NAFLD Activity Score) score were not associated with visfatin expression. There was a tendency of more evident visfatin liver expression in morbidly obese patients with diabetes mellitus. CONCLUSION Our study showed a positive association between visfatin and the fibrosis stage in NAFLD. This observation suggests a potential role of this adipokine in the pathogenesis and progression of NAFLD. Visfatin expression does not seem to be associated with liver steatosis and inflammation.

Abstract
The etiology and pathogenesis of autistic spectrum disorders (ASD) are still unknown. Platelet hyperserotonemia has been detected in 25-60% of autistic children. Higher incidence of gastrointestinal problems in people with autism is observed. The aim was compare the expression of platelet 5-HT(2A)r mRNA in autistic and non autistic groups. In a subgroup of patients with gastrointestinal problems an upper gastrointestinal tract endoscopy was performed and additionally the expression of 5-HT(2A) receptor mRNA in the duodenum was assessed. The examination was conducted in 79 children - 51 with ASD and 28 without autistic traits. Statistically significant differences between the study and control groups were proven in gastrointestinal problems. The analyses reveal a significantly higher level of 5-HT(2A)r mRNA in platelets of the study group patients, which could suggest serotonin system dysregulation.

Abstract
INTRODUCTION A consequence of diagnosis of adrenocortical carcinoma (ACC) is introduction of pharmacological therapy, precise monitoring of the patients and in some cases re-operation. The aim of the study is to analyse morphology of adrenocortical tumours as regards their malignancy by use of criteria proposed by Weiss. MATERIAL AND METHODS 110 adrenocortical tumours in 107 patients were analysed (M 27.1%, F 72.9%; age 32 to 77 years, mean 55.2 +/- 9.7). Conn syndrome was diagnosed in 16 patients (14.9%), Cushing syndrome in 12 (11.2%), and virilisation in 3 (2.8%). In 76 patients (71.0%) biochemical tests did not reveal hormonal hyperactivity of the tumour. RESULTS In routine histopatological examination ACC was diagnosed in 6 tumours (5.4%), adrenocortical adenoma (ACA) in 92 (83.6%) and adrenocortical hyperplasia in 12 (10.9%). Nuclear grade III or IV was observed in 8 tumours (7.3%), mitotic rate > 5/50 high power fields in 6 (5.4%), atypical mitoses in 5 (4.5%), clear cells constituting < 25% of the tumour in 10 (9.1%), diffuse architecture in 8 (7.3%), necrosis in 16 (14.5%), veins infiltration in 4 (3.6%), sinusoids infiltration in 7 (6.3%), and tumour capsule infiltration in 5 (4.5%). Among ACC tumours 4-9 features of malignancy were present, among ACA--0-3 features. Statistical analysis revealed correlation between number of criteria proposed by Weiss and maximal tumour size (p < 0.05). CONCLUSION The structure and cell arrangement in adrenocortical adenoma are heterogeneous. Application of criteria proposed by Weiss in histopathological examination of adrenocortical tumours can be useful in differentiating adrenocortical adenoma from carcinoma.

Abstract
BACKGROUND Adrenal pheochromocytoma are diagnosed the most often in patients with arterial hypertension or with thyroid medullar cancer and suspicion of MEN II syndromes. The aim of the study is to analyse the morphology of pheochromocytomas on the basis of Pheochromocytoma of the Adrenal Gland Scaled Score (PASS) in order to estimate their potential malignancy. MATERIAL AND METHODS Forty tumours were subjected to analysis. Mean patients age was 45.2+/-13.4 years. The diagnosis of pheochromocytoma was establish before surgery in 87.5%. 12.5% of patients were referred to surgery on the basis of tumour diameter (range 70 to 102 mm). In 20.0% of patients MEN II syndromes were diagnosed. RESULTS In pathological examination benign pheochromo-cytoma was diagnosed in 39 presented patients. In 1 cases malignant form of pheochromocytoma was diagnosed on the basis of lymph nodes metastases. Number of points in PASS was >or=4 in 9 of 40 tumours (22.5%). Among 35 patients operated on more than 12 months ago 2 patients died: 1 patient with malignant pheochromocytoma (PASS=8 points) and 1 patient with MEN IIA syndrome (due to disseminated thyroid medullar cancer). In remaining 7 observed patients with PASS>or=4 points neither recurrence nor metastases were diagnosed within the period of observation (13-90 months). In 1 out of patients with PASS<4 points a local recurrence was surgically removed 82 months after primary operation. CONCLUSION Analysis of pheochromocytoma in PASS is only of rough character and does not allow for clear-cut histological diagnosis of benign and malignant tumours. The only unquestionable criterion of pheochromocytoma's malignancy remain metastases.

Multicenter European trials estimating appropriateness of colonoscopy are one of the hot topics in gastroenterology. The aim of the study was the estimation of appropriateness of colonoscopy and usefulness of panel experts criteria (elaborated according to RAND/UCLA method) in Department of Gastroenterology of Medical University of Silesia in Katowice and other gastroenterology centers throughout Europe. The trial was conducted between January 1st 2001 and May 30th 2001 in 18 centers in 9 European countries. 307 patients, who signed informed consent, were recruited in Katowice, while 5697 patients were enrolled in the other centers. The data have been collected in a prospective manner on a dedicated sheet, prepared in the coordinating centre in Lausanne (Switzerland). The part of the sheet with evaluation of appropriateness of colonoscopy was filled in before the procedure. The endoscopic (and histopathologic if necessary) diagnosis was collected after the procedure. The data from all centers were analyzed in Lausanne and the results were sent to the participants. The comparison of results from Katowice and of all the other centers was performed in Katowice. We found out, that self-estimation (made by colonoscopist), but also what is much more important the estimation done according to objective criteria of the panel of experts were significantly higher in our department, than in the other participating centers. The overestimation of self-judgment has been significantly higher in the other centers, than in our department. The higher percentage of therapeutic colonoscopies in our department can be responsible for such results.

Abstract
A review of the international medical literature was conducted regarding the laryngeal neuroendocrine tumors. This paper discusses the diagnosis, histopathology, treatment, and prognosis in laryngeal neuroendocrine tumors. It also discusses the heterogenous classification schema of such tumors. Two cases of a very rare neuroendocrine cancer of larynx are described. Both were localized in the supraglottic area and occurred in the 5th and 6th decades of life, consistent with previously reported cases of such neoplasms.
