Abstract
In congenital hyperinsulinemic hypoglycemia - the most common cause of persistent hypoglycemia in infancy - a focal lesion can be identified in 50% of the cases. With appropriate medical care based upon early diagnosis, these patients can be cured by the resection of the lesion rendering unnecessary long time medical care, and avoiding serious brain damage from recurrent hypoglycemic episodes. Genetic testing and 18F-fluoro-dihydroxyphenylalanine PET/CT imaging are essential for determining the best possible treatment. We report 2 cases of focal congenital hyperinsulinism - both male infants: 22 and 2 months of age - treated successfully with enucleation of the pancreas lesion (Semmelweis University, Budapest). Both patients had the pathognomonic mutation of the ABCC8 gene of the ATP-sensitive potassium channel. Radiologic imaging and histology confirmed the diagnosis, and after the operation, pharmacological treatment was terminated in both cases. During the follow-up period (5 and 1.5 years, respectively) they are euglycemic, with no morbidities attributed to the operation. We believe that these two operations for focal hyperinsulinism - diagnosed and localised by the above detailed genetic and specific radiological testing - were the first of their kind in Hungary. Based on the acquired experience, every necessary examination can be achieved in our country to improve patient care, reduce morbidity and medical costs. Orv Hetil. 2023; 164(47): 1877-1884.

Abstract
Extracellular vesicles (EV) carry their cargo in a membrane protected form, however, their value in early diagnostics is not well known. Although pancreatic cysts are heterogeneous, they can be clustered into the larger groups of pseudocysts (PC), and serous and mucinous pancreatic cystic neoplasms (S-PCN and M-PCN, respectively). In contrast to PCs and S-PCNs, M-PCNs may progress to malignant pancreatic cancers. Since current diagnostic tools do not meet the criteria of high sensitivity and specificity, novel methods are urgently needed to differentiate M-PCNs from other cysts. We show that cyst fluid is a rich source of EVs that are positive and negative for the EV markers CD63 and CD81, respectively. Whereas we found no difference in the EV number when comparing M-PCN with other pancreatic cysts, our EV-based biomarker identification showed that EVs from M-PCNs had a higher level of miR-200b. We also prove that not only EV-derived, but also total cyst fluid miR-200b discriminates patients with M-PCN from other pancreatic cysts with a higher sensitivity and specificity compared to other diagnostic methods, providing the possibility for clinical applications. Our results show that measuring miR-200b in cyst fluid-derived EVs or from cyst fluid may be clinically important in categorizing patients.

Abstract
OBJECTIVE AND AIMS Acute pancreatitis in inflammatory bowel disease occurs mainly as an extraintestinal manifestation or a side effect of medications. We aimed to investigate the prognostic factors and severity indicators of acute pancreatitis and the treatment of patients with both diseases. DESIGN We performed a matched case-control registry analysis of a multicentre, prospective, international acute pancreatitis registry. Patients with both diseases were matched to patients with acute pancreatitis only in a 1:3 ratio by age and gender. Subgroup analyses were also carried out based on disease type, activity, and treatment of inflammatory bowel disease. RESULTS No difference in prognostic factors (laboratory parameters, bedside index of severity in acute pancreatitis, imaging results) and outcomes of acute pancreatitis (length of hospitalization, severity, and local or systemic complications) were detected between groups. Significantly lower analgesic use was observed in the inflammatory bowel disease population. Antibiotic use during acute pancreatitis was significantly more common in the immunosuppressed group than in the non-immunosuppressed group (p = 0.017). However, none of the prognostic parameters or the severity indicators showed a significant difference between any subgroup of patients with inflammatory bowel disease. CONCLUSION No significant differences in the prognosis and severity of acute pancreatitis could be detected between patients with both diseases and with pancreatitis only. The need for different acute pancreatitis management is not justified in the coexistence of inflammatory bowel disease, and antibiotic overuse should be avoided.

Abstract
Simple Summary The histological differential diagnosis of adrenocortical adenoma and carcinoma is difficult and requires great expertise. Measures taken towards the distinction of adrenal tumors are of paramount importance. The non-coding circular RNAs (circRNAs) were shown to be expressed in a tissue and tumor specific manner. CircRNAs are investigated as a useful adjunct to the differential diagnosis of benign and malignant tumors of several organs, but they have not been investigated in adrenocortical tumors yet. Here, we have performed circRNA profiling in adrenocortical tumors by next-generation sequencing to detect already known and de novo circRNAs. Out of the five most differentially expressed circRNAs, circPHC3 could be confirmed by TaqMan RT-qPCR to be overexpressed in carcinoma and adenoma vs. healthy tissues in an independent validation cohort. Abstract Differentiation of adrenocortical adenoma (ACA) and carcinoma (ACC) is often challenging even in the histological analysis. Circular RNAs (circRNAs) belonging to the group of non-coding RNAs have been implicated as relevant factors in tumorigenesis. Our aim was to explore circRNA expression profiles in adrenocortical tumors by next-generation sequencing followed by RT-qPCR validation. Archived FFPE (formalin-fixed, paraffin embedded) including 8 ACC, 8 ACA and 8 normal adrenal cortices (NAC) were used in the discovery cohort. For de novo and known circRNA expression profiling, a next-generation sequencing platform was used. CIRI2, CircExplorer2, AutoCirc bioinformatics tools were used for the discovery of circRNAs. The top five most differentially circRNAs were measured by RT-qPCR in an independent validation cohort (10 ACC, 8 ACA, 8 NAC). In silico predicted, interacting microRNAs potentially sponged by differentially expressed circRNAs were studied by individual RT-qPCR assays. We focused on overexpressed circRNAs here. Significantly differentially expressed circRNAs have been revealed between the cohorts by NGS. Only circPHC3 could be confirmed to be significantly overexpressed in ACC, ACA vs. NAC samples by RT-qPCR. We could not observe microRNA expression changes fully corresponding to our sponging hypothesis. To the best of our knowledge, our study is the first to investigate circRNAs in adrenocortical tumors. Further studies are warranted to explore their biological and diagnostic relevance.

Abstract
Fiziológiás terhesség során is jelentős morfológiai, funkcionális, hemodinamikai
változások történnek a vesében, melyek következtében kismértékben fokozódik a
proteinuria. Ennek kóros mértékű növekedése azonban, főleg ha hypertoniával,
illetve vesefunkció-beszűküléssel is jár, szoros anyai, valamint magzati nyomon
követést igényel, hiszen súlyos perinatalis szövődményeket vetíthet előre. A
proteinuria differenciáldiagnosztikája szerteágazó, az etiológia tisztázásakor
elsődleges szempont a praeeclampsia, illetve az egyéb, esetleges primer
vesebetegség elkülönítése. Sorra vesszük az etiológiai palettán fellelhető
mindazon kórképeket, amelyek akár a praeeclampsia tünettanát is utánozhatják,
megnehezítve ezáltal a pontos diagnózis felállítását. A 31 éves várandós esete
kapcsán a terhesség során észlelt progrediáló proteinuria
differenciáldiagnosztikáját tekintjük át. Postpartum egyértelművé vált a
praeeclampsia diagnózisa, mellékleletként azonban vesemalignitás igazolódott.
Arra is keressük a választ, vajon a vese rosszindulatú daganata felelőssé
tehető-e a hypertoniát, progrediáló proteinuriát magában foglaló klinikumért.

Abstract
Pancreatic necrosis is a consistent prognostic factor in acute pancreatitis (AP). However, the clinical scores currently in use are either too complicated or require data that are unavailable on admission or lack sufficient predictive value. We therefore aimed to develop a tool to aid in necrosis prediction. The XGBoost machine learning algorithm processed data from 2387 patients with AP. The confidence of the model was estimated by a bootstrapping method and interpreted via the 10th and the 90th percentiles of the prediction scores. Shapley Additive exPlanations (SHAP) values were calculated to quantify the contribution of each variable provided. Finally, the model was implemented as an online application using the Streamlit Python-based framework. The XGBoost classifier provided an AUC value of 0.757. Glucose, C-reactive protein, alkaline phosphatase, gender and total white blood cell count have the most impact on prediction based on the SHAP values. The relationship between the size of the training dataset and model performance shows that prediction performance can be improved. This study combines necrosis prediction and artificial intelligence. The predictive potential of this model is comparable to the current clinical scoring systems and has several advantages over them.

Abstract
Simple Summary The histological differential diagnosis of adrenocortical adenoma and carcinoma is difficult and requires great expertise. MiRNAs were shown to be useful for the differential diagnosis of benign and malignant tumors of several organs, and several findings have suggested their utility in adrenocortical tumors as well. Here, we have selected tissue miRNAs based on the literature search, and used machine learning to identify novel clinically applicable miRNA combinations. Combinations with high sensitivity and specificity (both over 90%) have been identified that could be promising for clinical use. Besides being a useful adjunct to histological examination, these miRNA combinations could enable preoperative adrenal biopsy in patients with adrenal tumors suspicious for malignancy. Abstract The histological analysis of adrenal tumors is difficult and requires great expertise. Tissue microRNA (miRNA) expression is distinct between benign and malignant tumors of several organs and can be useful for diagnostic purposes. MiRNAs are stable and their expression can be reliably reproduced from archived formalin-fixed, paraffin-embedded (FFPE) tissue blocks. Our purpose was to assess the potential applicability of combinations of literature-based miRNAs as markers of adrenocortical malignancy. Archived FFPE tissue samples from 10 adrenocortical carcinoma (ACC), 10 adrenocortical adenoma (ACA) and 10 normal adrenal cortex samples were analyzed in a discovery cohort, while 21 ACC and 22 ACA patients were studied in a blind manner in the validation cohort. The expression of miRNA was determined by RT-qPCR. Machine learning and neural network-based methods were used to find the best performing miRNA combination models. To evaluate diagnostic applicability, ROC-analysis was performed. We have identified three miRNA combinations (hsa-miR-195 + hsa-miR-210 + hsa-miR-503; hsa-miR-210 + hsa-miR-375 + hsa-miR-503 and hsa-miR-210 + hsa-miR-483-5p + hsa-miR-503) as unexpectedly good predictors to determine adrenocortical malignancy with sensitivity and specificity both of over 90%. These miRNA panels can supplement the histological examination of removed tumors and could even be performed from small volume adrenal biopsy samples preoperatively.

Abstract
OBJECTIVES This study aimed to characterise the clinicopathological features and prognostic factors of a large cohort of Hungarian patients with adrenocortical cancer diagnosed between 2000-2021. PATIENTS AND METHODS This retrospective study included seventy-four patients (27 men and 47 women) with histologically confirmed adrenocortical cancer in a single tertiary referral endocrine centre. Descriptive statistics were performed, providing summaries of selected clinical and pathological parameters. Clinicopathological factors contributing to overall survival were analysed. RESULTS The median age of patients was 48,5 years (17-84 years) at diagnosis. The majority of cases were diagnosed at ENSAT stage II (39,2%) and stage IV (33,8%). At diagnosis, the median tumour size was 9,0 cm (4,5-20 cm). In 47 patients (71,6%), the tumour was hormonally active. The median overall survival and the 5-year survival rate were 23,5 months (95% CI, 17-30,5 months) and 18,3%, respectively. Primary tumour resection was performed in 68 patients (91,8%); R0 surgical resection was achieved in 30 patients. In univariate Cox regression model, tumours with stages III and IV, high proliferative activity (Ki67-index > 10%), R1-R2 surgical resection state and hormonal activity were associated with poorer survival. Cortisol excess, both isolated and combined with androgen production, was associated with poorer survival. Fifty-five patients were treated with mitotane. The overall survival of patients achieving therapeutic mitotane plasma concentration was significantly better compared to those who never reached it [27.0 (2-175) months vs 18.0 (2-83) months; p<0.05)]. The median age, the distribution of gender, ENSAT stage, resection state and Ki67-index did not differ between these two groups. The time needed to reach the therapeutic range of serum mitotane was 96.5 days (95% CI, 75-133 days). CONCLUSION Our results confirm previous data that disease stage, mitotic activity, the resection state and the mitotane treatment achieving therapeutic concentration are the most critical parameters influencing the prognosis of adrenocortical cancer. Our data suggest that hormonal activity may be more frequent than described previously, and it is a strong and independent prognostic factor of overall survival. To our knowledge, this is the first single-centre study confirming the prognostic importance of achieving therapeutic mitotane concentration.

Abstract
Pancreatic cancer in the narrower sense is defined as pancreatic ductal adenocarcinoma (PDAC), which accounts for 95% of malignancies of the pancreas. The tumor has a very poor prognosis, one of the reasons being that it is often only recognized at an advanced, already metastatic stage. Another reason is that although oncotherapy has developed rapidly in recent decades, there has been no significant improvement in the treatment of these tumors. Based on Hungarian and international analyses, we can expect an increase in the number of patients in the coming decades, so research in any field of medicine is of paramount importance for early diagnosis and the development of more effective treatment strategies. However, it is important to know the other benign and malignant exocrine and neuroendocrine tumors, the precursor lesions, as the basic condition for proper treatment is an accurate pathological diagnosis. The summary presents the pathological diversity of tumors, detailing their macroscopic, microscopic, and immunohistochemical characteristics.

Abstract
The presence of autophagy has been indicated in cholangiocarcinoma (CC), which disease has poor prognosis and limited treatment options. Recently, CC has been classified by anatomical localization as intrahepatic (iCC), perihilar (pCC) and distal (dCC), showing different clinical and molecular characteristics. Thus, our aim was to compare autophagy activity in CC samples resected from different anatomical locations. Further, we investigated whether autophagy could be modulated in cell lines originated from iCC and extrahepatic CC (eCC) following the treatments with autophagy inhibitory and inducing agents. Tissue microarrays were prepared from 70 CC (28 iCC, 19 pCC and 23 dCC), 31 adjacent non-tumorous and 9 hepatocellular carcinoma (HCC) samples. Autophagy markers LC3, p62 and Beclin1 as well as proliferation marker Ki-67 were monitored by immunohistochemistry and were associated with patients' survival. Modulation of autophagy was investigated in cell lines originated from iCC (HuH-28), eCC (TFK-1) and HCC (HepG2) by treating the cells with chloroquine (CQ) for inhibition and with Rapamycin, 5-Fluorouracil (5-FU) and Sorafenib for induction of autophagy. Our results indicated an inhibited autophagy in iCC and pCC tumor tissues, whereas active autophagy seemed to occur in dCC, especially in samples displaying low Ki-67 index. Additionally, low level of Beclin1 and high level of Ki-67 were associated with poor overall survival in dCC, suggesting the prognostic role of these proteins in dCC. Beside a baseline autophagy detected in each cell line, Rapamycin and 5-FU induced autophagy in iCC and HepG2 cell lines, Sorafenib in iCC cells. A chemotherapy agent in combination with CQ decreased IC50 effectively in the cell lines where basal and/or induced autophagy were present. In conclusion, we revealed differences in the autophagy activities of CC tissues and cell lines originated from different anatomical locations, which might influence patients' treatment. Our results also suggest a prognostic role of Beclin1 and Ki-67 in dCC.

Abstract
Although the role of autophagy has been implicated in several forms of chronic hepatitis, it is still not fully understood. Active autophagy eliminates damaged molecules and organelles (such as mitochondria) by lysosomal degradation. In the present study, we aimed to examine and compare autophagy activity in chronic hepatitis C (CHC) and autoimmune hepatitis (AIH) by detecting the expression of autophagy (LC3 and p62) and mitochondrium-related (TOMM20) proteins, as well as the levels of selected microRNAs (miR-101, -155, -204 and - 224) known to be involved in the regulation of autophagy. In addition, the expression levels were related to pathohistological parameters. Liver biopsy samples, including 45 CHC and 18 AIH cases, were immunohistochemically stained for LC3, p62 and TOMM20 and the expression of miRNAs was determined using real-time PCR. We found elevated LC3 and p62 in AIH samples as compared with CHC ones, indicating an activated autophagy that is impaired in AIH as no degradation of p62 seemed to occur. Moreover, p62 showed strong correlation with necroinflammatory grades in the AIH group. The observed elevated levels of TOMM20 and p62 suggest a less efficient elimination of damaged mitochondria in AIH as opposed to CHC, in which autophagy seems to have a more active function. The level of miR-101 was increased in case of CHC as compared with AIH, however, miR-155, -204 and 224 resulted in no expressional. Furthermore, miR-224 level correlated with steatosis and miR-155 expression with fibrosis stage in CHC. In conclusion, dissimilar autophagic activity was observed in CHC and AIH, suggesting a close association between impaired autophagy and severity of necroinflammation. This impairment may not be regulated by the analyzed miRNAs. Nevertheless, miR-224 and - 155 seem to be associated with CHC progression.

Abstract
PURPOSE Multiple endocrine neoplasia type 1 is a rare tumor syndrome caused by germline mutations of MEN1 gene. Phenotype varies widely, and no definitive correlation with the genotype has been observed. Mutation-negative patients with MEN1-associated tumors represent phenocopies. By comparing mutation-positive and mutation-negative patients, we aimed to identify phenotype features predictive for a positive genetic test and to evaluate the role of MEN1 mutations in phenotype modulation. METHODS Mutation screeening of MEN1 gene by Sanger sequencing and assessment of clinical data of 189 consecutively enrolled probands and relatives were performed at our national and European Reference Center. Multiple ligation probe amplification analysis of MEN1 gene and Sanger sequencing of CDKN1B were carried out in clinically suspicious but MEN1-negative cases. RESULTS Twenty-seven probands and twenty family members carried MEN1 mutations. Five mutations have not been described earlier. Pronouncedly high number of phenocopies (>70%) was observed. Clinical suspicion of MEN1 syndrome emerged at significantly earlier age in MEN1-positive compared to MEN1-negative probands. Gastroenteropancreatic neuroendocrine tumors developed significantly earlier and more frequently in carriers compared to non-carriers. Probands with high-impact (frameshift, nonsense, large deletions) mutations, predicted to affect menin function significantly, developed GEP-NETs more frequently compared to low-impact (inframe and missense) mutation carriers. CONCLUSIONS MEN1 phenocopy is common and represents a significant confounder for the genetic testing. GEP-NET under 30 years best predicted a MEN1 mutation. The present study thus confirmed a previous proposal and suggested that GEP-NET under 30 years should be considered as a part of the indication criteria for MEN1 mutational analysis.

Abstract
Cholangiocarcinoma (CC) is the second most common tumor of the liver, originating from the biliary system with increasing incidence and mortality worldwide. Several new classifications review the significance of tumor localization, site of origin, proliferation and biomarkers in the intrahepatic, perihilar and distal forms of the lesion. Based on growth pattern mass-forming, periductal-infiltrating, intraductal, undefined and mixed types are differentiated. There are further subclassifications which are applied for the histological features, in particular for intrahepatic CC. Recognition of the precursors and early lesions of CC including biliary intraepithelial neoplasia (BilIN), intraductal papillary neoplasm of the bile ducts (IPNB), biliary mucinous cystic neoplasm (MCNB) and the candidate precursors, such as bile duct adenoma and von Meyenburg complex is of increasing significance. In addition to the previously used biliary markers detected by immunohistochemistry, several new markers have been added to the differentiation of both the benign and malignant lesions, which can be used to aid in the subclassification in association with the outcome of CC. Major aspects of biliary carcinogenesis have been revealed, yet, the exact way of this diverse process is still unclear. The factors contributing to molecular cholangiocarcinogenesis include various risk factors, different anatomical localizations, multiple cellular origins, genetic and epigenetic alterations, tumor microenvironment, heterogeneity and clonal evolution. Driver mutations have been identified, implying that they are optimal candidates for targeted therapy. The most promising therapeutic candidates have entered clinical trials.

Abstract
INTRODUCTION Adrenal myelolipoma (AML) is the second most common and invariably benign primary adrenal neoplasm. Due to the variable proportion of fat and hematopoietic elements and its often large size, it can cause differential diagnostic problems. Several reports confirmed the utility of miRNAs in the diagnosis of tumors, but miRNA expression in AML has not yet been investigated. MATERIALS AND METHODS Next-generation sequencing (NGS) was performed on 30 formalin-fixed, paraffin-embedded (FFPE) archived tissue samples [10 each of AML, adrenocortical adenoma (ACA), and adrenocortical carcinoma (ACC)]. Validation was performed by real-time quantitative reverse transcription polymerase chain reaction on a cohort containing 41 further FFPE samples (15 AML, 14 ACA, and 12 ACC samples). Circulating miRNA counterparts of significantly differentially expressed tissue miRNAs were studied in 33 plasma samples (11 each of ACA, ACC, and AML). RESULTS By NGS, 256 significantly differentially expressed miRNAs were discovered, and 8 of these were chosen for validation. Significant overexpression of hsa-miR-451a, hsa-miR-486-5p, hsa-miR-363-3p, and hsa-miR-150-5p was confirmed in AML relative to ACA and ACC. hsa-miR-184, hsa-miR-483-5p, and hsa-miR-183-5p were significantly overexpressed in ACC relative to ACA but not to AML. Circulating hsa-miR-451a and hsa-miR-363-3p were significantly overexpressed in AML, whereas circulating hsa-miR-483-5p and hsa-miR-483-3p were only significantly overexpressed in ACC vs ACA. CONCLUSIONS We have found significantly differentially expressed miRNAs in AML and adrenocortical tumors. Circulating hsa-miR-451a might be a promising minimally invasive biomarker of AML. The lack of significantly different expression of hsa-miR-483-3p and hsa-miR-483-5p between AML and ACC might limit their applicability as diagnostic miRNA markers for ACC.

Abstract
Tumors arising from the diffuse neuroendocrine (NE) system are mostly located in gastro-entero-pancreatic (GEP) tract and in the lung, and show increasing incidence and wide spectrum appearance. Different therapeutic possibilities need accurate diagnosis, classification and prognosis prediction, which determination for pathological diagnostics is a great challenge. All of these are based on the WHO classification, TNM classification of tumors of different location, and clinicopathological characterization. This review provides a comprehensive overview of the general characteristics of NE tumors, in particular the clinical-pathological properties of gastro-entero-pancreatic tumors and the requirements of correct pathological diagnosis for treatment.

Abstract
Aquaporins (AQPs) facilitate the transepithelial water flow involved in epithelial fluid secretion in numerous tissues; however, their function in the pancreas is less characterized. Acute pancreatitis (AP) is a serious disorder in which specific treatment is still not possible. Accumulating evidence indicate that decreased pancreatic ductal fluid secretion plays an essential role in AP; therefore, the aim of this study was to investigate the physiological and pathophysiological role of AQPs in the pancreas. Expression and localization of AQPs were investigated by real-time PCR and immunocytochemistry, whereas osmotic transmembrane water permeability was estimated by the dye dilution technique, in Capan-1 cells. The presence of AQP1 and CFTR in the mice and human pancreas were investigated by immunohistochemistry. Pancreatic ductal HCO3- and fluid secretion were studied on pancreatic ducts isolated from wild-type (WT) and AQP1 knock out (KO) mice using microfluorometry and videomicroscopy, respectively. In vivo pancreatic fluid secretion was estimated by magnetic resonance imaging. AP was induced by intraperitoneal injection of cerulein and disease severity was assessed by measuring biochemical and histological parameters. In the mice, the presence of AQP1 was detected throughout the whole plasma membrane of the ductal cells and its expression highly depends on the presence of CFTR Cl- channel. In contrast, the expression of AQP1 is mainly localized to the apical membrane of ductal cells in the human pancreas. Bile acid treatment dose- and time-dependently decreased mRNA and protein expression of AQP1 and reduced expression of this channel was also demonstrated in patients suffering from acute and chronic pancreatitis. HCO3- and fluid secretion significantly decreased in AQP1 KO versus WT mice and the absence of AQP1 also worsened the severity of pancreatitis. Our results suggest that AQP1 plays an essential role in pancreatic ductal fluid and HCO3- secretion and decreased expression of the channel alters fluid secretion which probably contribute to increased susceptibility of the pancreas to inflammation.

Abstract
INTRODUCTION 1,25-Dihydroxy vitamin D3 mediates antitumor effects in hepatocellular carcinoma. AIM We examined mRNA and protein expression differences in 1,25-Dihydroxy vitamin D3-inactivating CYP24A1, mRNA of activating CYP27B1 enzymes, and that of VDR between human hepatocellular carcinoma and surrounding non-tumorous liver. METHODS Snap-frozen tissues from 13 patients were studied for mRNA and protein expression of CYP24A1. Paraffin-embedded tissues from 36 patients were used to study mRNA of VDR and CYP27B1. mRNA expression was measured by RT-PCR, CYP24A1 protein was detected by immunohistochemistry. RESULTS Expression of VDR and CYP27B1 was significantly lower in hepatocellular carcinoma compared with non-tumorous liver (p<0.05). The majority of the HCC samples expressed CYP24A1 mRNA, but neither of the non-tumorous liver. The gene activation was followed by CYP24A1 protein synthesis. CONCLUSIONS The presence of CYP24A1 mRNA and the reduced expression of VDR and CYP27B1 mRNA in human hepatocellular carcinoma samples indicate decreased bioavailability of 1,25-Dihydroxy vitamin D3, providing an escape mechanism from the anti-tumor effect.

Abstract
AIM: To evaluate the role of microRNA (miR)-146a, -155 and -122 in the duodenal mucosa of pediatric patients with Crohn’s disease (CD) and the effect of transforming growth factor-β (TGF-β) on these miRs in duodenal epithelial and fibroblast cells.
METHODS: Formalin-fixed, paraffin-embedded biopsies derived from the macroscopically inflamed (CD inflamed: n = 10) and intact (CD intact: n = 10) duodenal mucosa of pediatric CD patients and control children (C: n = 10) were examined. Expression of miR-146a, -155 and -122 was determined by real-time polymerase-chain reaction (PCR). The expression of the above miRs was investigated in recombinant human TGF-β (1 nmol/L, 24 h) or vehicle treated small intestinal epithelial cells (CCL-241) and primary duodenal fibroblast cells derived from healthy children as well.
RESULTS: Expression of miR-146a was significantly higher in the inflamed duodenal mucosa compared to the intact duodenal mucosa of children with CD (CD inflamed: 3.21 ± 0.50 vs CD intact: 0.62 ± 0.26, P≤ 0.01) and to the control group (CD inflamed: 3.21 ± 0.50 vs C: 1.00 ± 0.33, P≤ 0.05). The expression of miR-155 was significantly increased in the inflamed region of the duodenum compared to the control group (CD inflamed: 4.87 ± 1.02 vs Control: 1.00 ± 0.40, P≤ 0.001). The expression of miR-122 was unchanged in the inflamed or intact mucosa of CD patients compared to controls. TGF-β treatment significantly decreased the expression of miR-155 in small intestinal epithelial cells (TGF-β: 0.7 ± 0.083 vs Control: 1 ± 0.09, P≤ 0.05) and also the expression of miR-146a (TGF-β: 0.67 ± 0.04 vs Control: 1 ± 0.15, P≤ 0.01) and miR-155 (TGF-β: 0.72 ± 0.09 vs Control: 1 ± 0.06, P≤ 0.05) in primary duodenal fibroblasts compared to corresponding vehicle treated controls. TGF-β treatment did not influence the expression of miR-122.
CONCLUSION: The elevated expression of miR-146a and -155 in the inflamed duodenal mucosa of CD patients suggests the role of these miRs in the pathomechanism of inflammatory bowel disease. Anti-inflammatory TGF-β plays an important role in the regulation of the expression of these miRs.

Abstract
BACKGROUND & AIMS Excessive consumption of ethanol is one of the most common causes of acute and chronic pancreatitis. Alterations to the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) also cause pancreatitis. However, little is known about the role of CFTR in the pathogenesis of alcohol-induced pancreatitis. METHODS We measured CFTR activity based on chloride concentrations in sweat from patients with cystic fibrosis, patients admitted to the emergency department because of excessive alcohol consumption, and healthy volunteers. We measured CFTR levels and localization in pancreatic tissues and in patients with acute or chronic pancreatitis induced by alcohol. We studied the effects of ethanol, fatty acids, and fatty acid ethyl esters on secretion of pancreatic fluid and HCO3(-), levels and function of CFTR, and exchange of Cl(-) for HCO3(-) in pancreatic cell lines as well as in tissues from guinea pigs and CFTR knockout mice after administration of alcohol. RESULTS Chloride concentrations increased in sweat samples from patients who acutely abused alcohol but not in samples from healthy volunteers, indicating that alcohol affects CFTR function. Pancreatic tissues from patients with acute or chronic pancreatitis had lower levels of CFTR than tissues from healthy volunteers. Alcohol and fatty acids inhibited secretion of fluid and HCO3(-), as well as CFTR activity, in pancreatic ductal epithelial cells. These effects were mediated by sustained increases in concentrations of intracellular calcium and adenosine 3',5'-cyclic monophosphate, depletion of adenosine triphosphate, and depolarization of mitochondrial membranes. In pancreatic cell lines and pancreatic tissues of mice and guinea pigs, administration of ethanol reduced expression of CFTR messenger RNA, reduced the stability of CFTR at the cell surface, and disrupted folding of CFTR at the endoplasmic reticulum. CFTR knockout mice given ethanol or fatty acids developed more severe pancreatitis than mice not given ethanol or fatty acids. CONCLUSIONS Based on studies of human, mouse, and guinea pig pancreata, alcohol disrupts expression and localization of the CFTR. This appears to contribute to development of pancreatitis. Strategies to increase CFTR levels or function might be used to treat alcohol-associated pancreatitis.

Abstract
The vitamin D system is deregulated during development and progression of several cancer types. Data on the expression of the vitamin D system in the diseased pancreas are missing. The aim of this study was to investigate the expression of the vitamin D receptor (VDR), 1,25-dihydroxyvitamin D3 24-hydroxylase (CYP24A1), and the calcium-sensing receptor (CaSR), a vitamin D target gene, in the different regions of the pancreas in patients with chronic pancreatitis (n=6) and pancreatic ductal adenocarcinomas (PDAC) (n=17). We analyzed the expression of these genes at mRNA and protein level with quantitative real-time RT-PCR and immunostaining. mRNA expression of CYP24A1 and VDR was significantly increased in tumors compared with the adjacent non-tumorous tissue (p<0.01), while CaSR mRNA expression decreased. Both the VDR and the CaSR protein were highly expressed in the endocrine compared with the exocrine pancreas. In CP the CYP24A1 expression was highest in the endocrine pancreas, while in PDACs in the transformed ducts. In the PDAC patients CYP24A1 expression in the islets was significantly lower than in CP patients. Our data suggest that during ductal adenocarcinoma development the vitamin D system in the pancreas becomes deregulated on two levels: in the islets CYP24A1 expression decreases weakening the negative feedback regulation of the vitamin D-dependent insulin synthesis/secretion. In the transformed ducts CYP24A1 expression increases, impairing the antiproliferative effect of vitamin D in these cells.

Abstract
The optimal oncological result of radical prostatectomy (RP) is complete removal of the prostate gland and seminal vesicles with negative surgical margins. Preoperative diagnostic biopsies are examined and reported by the pathologist according to standardized rules. Staging of the disease is based on modern preoperative image analysis, most commonly multiparametric MRI. Pathological assessment and reporting of RP specimens is based on the International Society of Uropathology guidelines issued by the 2009 Consensus Conference. Positive surgical margin (PSM) is reported by the pathologist in approximately 1/3rd of RP cases. PSM increases the risk of biochemical, local and systemic progression. Pseudo-whole mount assessment of these specimens is the basis for radio-pathological correlation, thus providing quality control for preoperative MRI as well as assisting preoperative image analysis, sampling and diagnostic workup.

Abstract
AIM 1,25-Dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) inhibits cell growth and induces apoptosis in numerous types of tumors. We aimed to examine the mRNA and protein expression of 1,25(OH)(2)D(3)-inactivating CYP24A1 and mRNA expression of the activating CYP27B1 enzymes, as well as that of vitamin D receptor (VDR), in hepatocellular carcinoma (HCC) cell cultures in response to 1,25(OH)(2)D(3) administration. MATERIALS AND METHODS Increasing amounts of 1,25(OH)(2)D(3) (0.256-10 nM) were added to cultures of HepG2, Huh-Neo, Hep3B, Huh5-15 human HCC cell lines and cells then incubated for various time periods (30 min-28 h). The mRNA expression was analyzed by real time reverse transcription-polymerase chain reaction (RT-PCR). CYP24A1 protein in HepG2 cells was detected by immuncytochemistry. RESULTS CYP24A1 mRNA expression significantly (p<0.0001) increased in response to 1,25(OH)(2)D(3) administration in two cell lines: in HepG2 cells, the CYP24A1 mRNA level exhibited 5,300-fold elevation, reaching a maximum value at 8 h; in Huh-Neo cells, the increase was 152-fold that of the baseline value, with the maximum being reached at 14 h. There was no significant change in Hep3B and Huh5-15 cell lines, nor was there any change in CYP27B1 and VDR gene expression in any cell cultures. Immuncytochemistry in HepG2 cells proved that gene activation was followed by CYP24A1 protein synthesis. CONCLUSION Our novel data indicate that administration of 1,25(OH)(2)D(3) results in a marked increase of CYP24A1 mRNA expression in some, but not all, human HCC lines in vitro. These differences could be dependent upon the origin of the tumor cells.

Abstract
AIMS Tricellulin is a member of the family of tight junction proteins, which are found concentrated mainly at tricellular contacts. Altered expression of several tight junction components has been observed during carcinogenesis. In the present study, we have analysed the expression of tricellulin in normal human pancreas, and in primary exocrine and endocrine pancreatic tumours. METHODS AND RESULTS A total of 96 cases were studied: 20 normal pancreas, 58 pancreatic ductal adenocarcinomas, 15 pancreatic endocrine neoplasms, and three acinar cell carcinomas. Immunohistochemistry (analysed by digital morphometry), immunofluorescence, western blot analysis and reverse transcription polymerase chain reaction were performed. Tricellulin was localized apically in normal ducts and acini as intensive, spotty immunopositivity at tricellular contacts, whereas weaker signals were observed at the junction between two cells. Islets of Langerhans were negative. Well-differentiated ductal adenocarcinomas significantly overexpressed tricellulin as compared with poorly differentiated adenocarcinomas. Acinar cell carcinomas expressed tricellulin in tumour cells. All endocrine tumours were tricellulin-negative. CONCLUSIONS This is the first report to describe the tricellulin expression profile in normal and neoplastic human pancreas. Both normal and neoplastic pancreatic exocrine tissues expressed tricellulin, whereas no expression was seen in normal or neoplastic endocrine cells. Tricellulin expression in pancreatic ductal adenocarcinomas showed a significant negative correlation with the degree of differentiation.

Abstract
BACKGROUND & AIMS The effects of trypsin on pancreatic ductal epithelial cells (PDECs) vary among species and depend on the localization of proteinase-activated receptor 2 (PAR-2). We compared PAR-2 localization in human and guinea-pig PDECs, and used isolated guinea pig ducts to study the effects of trypsin and a PAR-2 agonist on bicarbonate secretion. METHODS PAR-2 localization was analyzed by immunohistochemistry in guinea pig and human pancreatic tissue samples (from 15 patients with chronic pancreatitis and 15 without pancreatic disease). Functionally, guinea pig PDECs were studied by microperfusion of isolated ducts, measurements of intracellular pH and intracellular Ca(2+) concentration, and patch clamp analysis. The effect of pH on trypsinogen autoactivation was assessed using recombinant human cationic trypsinogen. RESULTS PAR-2 localized to the apical membrane of human and guinea pig PDECs. Trypsin increased intracellular Ca(2+) concentration and intracellular pH and inhibited secretion of bicarbonate by the luminal anion exchanger and the cystic fibrosis transmembrane conductance regulator (CFTR) Cl(-) channel. Autoactivation of human cationic trypsinogen accelerated when the pH was reduced from 8.5 to 6.0. PAR-2 expression was strongly down-regulated, at transcriptional and protein levels, in the ducts of patients with chronic pancreatitis, consistent with increased activity of intraductal trypsin. Importantly, in PAR-2 knockout mice, the effects of trypsin were markedly reduced. CONCLUSIONS Trypsin reduces pancreatic ductal bicarbonate secretion via PAR-2-dependent inhibition of the apical anion exchanger and the CFTR Cl(-) channel. This could contribute to the development of chronic pancreatitis by decreasing luminal pH and promoting premature activation of trypsinogen in the pancreatic ducts.

Abstract
Claudins (CLDNs) are essential proteins of tight junctions. Changes in their expression pattern have been demonstrated in a number of tumors. CLDNs-3 and -4 are receptors of the Clostridium perfringens enterotoxin, cytolytic effects of the toxin are well known. The aim of our studies was to compare the different CLDN expression patterns in normal pancreas cells, pancreatic endocrine tumors, adenocarcinomas, mucinous cystic tumors and acinar cell carcinomas. Expressions of CLDN-1, -2, -3, -4 and -7 proteins were examined using immunohistochemical as well as RT-PCR techniques and the following observations were made: 1.) In addition to the well-known CLDN-1 and -4 expression CLDN-2, -3 and -7 proteins were demonstrated in ductal cells, while CLDN-3 and -7 proteins showed expression in acinar cells. Expression of CLDNs-3 and -7 was manifest in endocrine cells. 2.) CLDN-3 and -7 proteins showed high expression in endocrine tumors, CLDN-1, -2, and -4 proteins in exocrine tumors. This is the first description of CLDN protein expression in endocrine tumors. 3.) The level of CLDN-1, -4 and -7 protein expression in borderline cystic tumors is in between that of benign and malignant tumors. This supports the sequential development theory regarding mucinous cystic tumors. 4.) This is a first review on childhood acinar cell carcinoma causing Cushing syndrome. According to our results the following conclusions are made. 1.) The presence of CLDN-3 refers to endocrine differentiation. The adenocarcinomas and cystic mucinous tumors of exocrine origin denoted CLDN-1, -2, -4 and -7 positivity, whereas acinar cell carcinomas expressed only CLDN-1 and -2. Considering the CLDN expression observed in normal pancreas cells, it can be established that CLDN-1, -2 and -4 proteins are definitely markers of ductal differentiation, CLDN-1 protein of acinar and CLDN-3 of endocrine differentiation. 2). The increased CLDN-4 expression in adenocarcinomas and mucinous cystic tumors, as well as the high CLDN-3 expression in endocrine tumors may open up new prospects in the targeted therapy of these tumors. 3). The claudin expression pattern of pancreas tumors may be employed in the differential diagnosis of these tumors and may be of help in deciding dignity.

Abstract
The purpose of the study was to identify breast cancer subtypes by immunohistochemistry likely to respond to neoadjuvant chemotherapy and to analyze the used chemotherapy regimen and the range of response rates. Analysis of a collected database was performed. Ninety-two patients were identified in our files who received neoadjuvant chemotherapy between 1998 and 2009. We used immunohistochemical profiles (ER, PgR, HER2, Ki-67 and p53) of NCB, FNAB and surgical breast specimens to subclassify the tumors. Pathological response rates were assessed following surgical removal of tumors by using the Chevallier classification. DFS and OS was measured in 88 cases from the date of definitive surgery to the date of last follow-up or death. Pathological complete or near-complete remission (pCR = Chevallier I and II) was observed in 13 of 92 cases (14.1%). According to the preoperative characteristics of the 13 tumors achieving pCR, 9 of the cases were triple negative, one of 13 was ER-/HER2+ and three of 13 ER+/HER2+. Twenty-four of 92 patients received taxane based neoadjuvant chemotherapy, 30 of 92 anthracycline based neoadjuvant chemotherapy, 33 of 92 taxane + anthracycline regimen and 2 of 92 CMF regimen. In the taxane treated group of patients the pCR rate was 29.1%, in the anthracycline group 6.6% and in the taxane + anthracycline treated group 12.1%. Concerning DFS, significant difference was observed between the Chevallier III and IV groups (p=0.006), and less events were observed in the pCR group (not significant). pCR was associated with significantly better OS (p=0.050). It seems that even limited, routinely used immunohistochemical profiling of tumors is able to predict the likelihood of pCR to neoadjuvant chemotherapy. Patients with triple negative and HER2-positive cancers are likely to achieve pCR after neoadjuvant chemotherapy.

Abstract
The main autocrine/paracrine role of the active metabolite of vitamin D(3), 1alpha,25-dihydroxyvitamin D(3) (1,25-D(3)), is inhibition of cell growth and induction of cell differentiation and/or apoptosis. Synthesis and degradation of the secosteroid occurs not only in the kidney but also in normal tissue or malignant extrarenal tissues such as the colon. Because 25-hydroxyvitamin D(3) 24-hydroxylase (CYP24A1) is considered to be the main enzyme determining the biological half-life of 1,25-D(3), we have examined expression of the CYP24A1 mRNA (by real-time RT-PCR) and protein (by immunohistochemistry) in normal human colon mucosa, colorectal adenomas, and adenocarcinomas in 111 patients. Although 76% of the normal and benign colonic tissue was either completely devoid of or expressed very low levels of CYP24A1, in the majority of the adenocarcinomas (69%), the enzyme was present at high concentrations. A parallel increased expression of the proliferation marker Ki-67 in the same samples suggests that overexpression of CYP24A1 reduced local 1,25-D(3) availability, decreasing its antiproliferative effect.

Abstract
OBJECTIVES To study the treatment and short-term outcome of 16 consecutive cases of sclerosing lipogranuloma of penis developing after Vaseline inoculation for penile augmentation. METHODS After Vaseline inoculation, patient pain was related mainly to erection and severe phimosis. At surgical reconstruction complete and radical excision of the involved penile skin was performed, followed by skin substitution from the existing, saved coat of the penis. In most cases the stored, uninvolved inner preputial skin was used; less frequently scrotal flaps and in the least-favorable cases penis embedment in the scrotum was applied for coverage of the penis. RESULTS All 16 patients were cured, no matter how long after self-injection vaselinoma developed or which kind of surgery was performed. Histopathologic evaluation revealed different findings according to the time elapsed after Vaseline injection. CONCLUSIONS Early detection of patients with Vaseline penile augmentation and urgent surgery are essential because the best esthetic and functional results can be achieved in the acute period; this is when granuloma does not involve the subdermal but only the subcutaneous layer and local penile flaps can most commonly be used for reconstruction.

Abstract
Altered expression of recently described claudins (CLDNs) as members of tight junction (TJ) transmembrane proteins was noted in several malignancies. We aimed to analyze protein and messenger RNA (mRNA) expressions of different CLDNs in human pancreatic endocrine tumors (PET) and ductal adenocarcinomas. A total of 45 formalin-fixed, paraffin-embedded samples were studied. Immunohistochemistry and real-time reverse transcriptase polymerase chain reaction analysis were carried out for quantification of CLDN 1, -2, -3, -4, and -7 expressions. Normal acini and ducts showed strong CLDNs 1, -3, -4, and -7 and scattered CLDN 2 protein expressions, while Langerhans islands revealed only CLDN 3 and -7 expressions. CLDN 2 expression was found in the half of ductal adenocarcinomas, while the vast majority of endocrine tumors were negative. CLDN 1, -4, and -7 immunohistochemistry was positive in all adenocarcinomas, whereas endocrine tumors were completely negative for CLDNs 1 and -4. CLDN 3 and -7 proteins were detected in all endocrine tumors, while CLDN 3 in ductal adenocarcinomas was negative. The mRNA expression of CLDNs showed differences between endocrine tumors and ductal adenocarcinomas, similar as found for protein expression. Our findings support that PET and ductal carcinomas are specifically characterized by different expression pattern of CLDNs. High expressions of CLDN 3 in endocrine tumors and CLDN 4 in ductal carcinomas might attract them as targets for adjuvant therapy.

Abstract
A case of pancreatic acinar cell tumor (ACC) is presented in a 10-year-old boy. The tumor manifested clinically with Cushing's syndrome, high serum adrenocorticotropic hormone (ACTH) and cortisol concentrations. In addition, excessive serum levels of alpha-fetoprotein (AFP) were detected. Surgical resection was not possible due to retroperitoneal invasion. Biopsy of the mass showed a solid, poorly differentiated ACC of the pancreas. Periodic acid Schiff positive cytoplasmic granules, trypsinogen, keratins, alpha-1-antitrypsin, and AFP were identified in the tumor cells. Electron microscopy demonstrated zymogen granules as well as isolated dense core granules. Using immunochemiluminometric assay, a high quantity of ACTH was found in the fresh frozen tumor extract. ACTH, chromogranin A, and corticotropin-releasing factor were identified only in a few cells by immunohistochemistry. Combined radiochemotherapy was temporarily effective in reducing the tumor mass and serum AFP. Serum ACTH and cortisol levels dropped progressively and definitively to normal values after chemotherapy, and the Cushing's syndrome subsided. Two years later, the patient died with metastatic disease. The presented case of ACC is interesting due to high serum AFP values and ectopic ACTH secretion resulting in Cushing's syndrome.

Abstract
UNLABELLED Lichen sclerosus in urological practice. INTRODUCTION Lichen sclerosus is a sclerosing, inflammatory skin disease with unknown origin which causes secondary phimosis of the foreskin and stricture of the urethra. In the case of long term existence of it the prevalence of intraepithelial squamous cell neoplasia is increased. AIM To identify the role of lichen sclerosus in adulthood phimosis and to categorize urological treatment. To define the proper therapy of lichen sclerosus, causing meatal and urethral stricture. To measure the incidence of lichen sclerosus in patients with squamous cell neoplasia. METHOD There was looked the incidence of lichen sclerosus in patient suffering with phimosis, recurrent urethral stricture, therapeutical options and presence of lichen sclerosus in patient with penile squamous cell neoplasia. RESULTS There were 123 foreskins sent for histological examination from 624 patients operated with circumcision in the last 5 years in the clinic. There were 76 (62%) times lichen sclerosus justified in 123 foreskins. There were lichen sclerosus found in 90% (9/10) of excised tissues of recurrent urethral strictures. There were lichen sclerosus noticed in 3 of 10 (33%) penile squamous cell carcinoma slides. CONCLUSIONS Lichen sclerosus can be detected in significant proportion of phimosis in adulthood. Lichen sclerosus can be found very often as the cause of recurrent urethral strictures, which takes necessary to perform 2 steps reconstructive operation with complete excision of the urethra and buccal graft emplacement. In the third of our all squamous cell carcinoma cases lichen sclerosus could be histologically shown, which give good reason for the opportunity of malignant disease development of this dermatological illness.

Abstract
Pure rhabdomyosarcomas occurring in the adult uterus are very rare, with poor prognosis. We present a case of a 67-year-old woman with postmenopausal vaginal bleeding caused by pleomorphic rhabdomyosarcoma of the uterus, treated with hysterectomy, bilateral salpingo-oophorectomy, pelvic/paraaortic lymphadenectomy and partial sigmoidectomy. Postoperative chemotherapy (Doxorubicin) was given according to protocol. Follow-up examinations one year after surgery revealed no abnormalities or tumor recurrence. The rarity of this histological entity makes the presented case worthy of publication.

Abstract
Congenital primary intracranial hemangiopericytomas are exceptionally rare tumors. We present a case of a fetus, with the prenatal sonogram at 33 weeks of gestation revealing a large cerebral tumor. Because of the enlarged head, a cesarean section was performed. The tumor was confirmed by postnatal ultrasound, magnetic resonance imaging (MRI) and biopsy. Elevated intracranial pressure and hemorrhage led to death on the 11th day. Autopsy revealed a 10x9 cm large inhomogeneous tumor located centrally, mainly in the posterior fossa. Histology showed a hypercellular and hypervascular tumor with extended necrosis and high mitotic rate. The tumor cells were positive for vimentin and CD34 antigens and negative for several neurological markers, desmin and CD31. The diagnosis of a congenital primary cerebral hemangiopericytoma was confirmed.

Abstract
The authors analyze early postoperative results of 320 patients operated on because of aortoiliac occlusion. The mortality of the interventions was 4.1%, the proportion of reocclusions was 7.2% and the rate of amputations was 3.1%. The operations were as follows: 88 aorto-bifemoral bypasses, 157 iliofemoral bypasses, 75 iliofemoral thrombendarteriectomies. There were no statistical variations in the rate of mortality, complications and amputations between different types of operations. Comparing the results of aortobifemoral bypasses with opening of the peritoneal cavity (6 patients died of 74, i.e. 8.1%) with those performed retroperitoneally (14 patients no death), despite the marked difference there was no significant difference probably due to the small number of patients (p = 0.34). In 26% it was necessary to extend the reconstructions distally to peripheral arteries or deep onto the profundal femoral artery. The peripheral extension did not effect early mortality, or amputation rate. Seven patients needed reoperation because of general surgical reasons, with 2 mortalities (28.6%), both had bowel necrosis; mortality rate was significantly higher compared to other patients (p < 0.05). Vascular complications developed in 30 cases. The mortality and the amputation rate of 27 reoperated patients was 3.7%, which did not differ significantly from the results of other patients group. Fifteen operations were carried out because of acute ischaemia, 4 patients were lost (26.7%), significantly more than after elective operations (305/9, 2.95%, p < 0.01). In our department retroperitoneal approach in aortobifemoral bypasses decreased mortality. If the quality of the outflow is uncertain or insufficient, one has to consider immediate distal extension. We must to do everything to prevent--or to diagnose and treat--bowel necrosis. The mortality rate of aortoiliac occlusions causing acute ischaemia is high, therefore we must consider the adoption of extraanatomical bypasses.

Abstract
The authors present a particular case of an acute pancreatitis. The disease developed in a young male patient following cholelithiasis and cholecystectomy. The inflammation affected the outer layers of the pancreas as a mantle and it caused widespread fat necrosis. Necrectomy for septic state was conducted to improve the condition, but the patient died of pulmonary embolism. Unexpectedly big necrotic areas of fat necrosis and abscess were found at autopsy.

Abstract
The aim of this study was to analize clinical diagnoses and histopathological reports in 185 cases of male infertility, investigated by testicular biopsies in the period 1993-1997. The classical objective of such investigations has been to clarify either obstructive, or so-called secretory lesions resulting in azoospermia. Histologically normal spermatogenesis was reported in 8 patients (4.3%). Hypospermatogenesis proved to be the most frequent pathologic lesion (69 cases, 37.3%), followed by maturation arrest (61 cases, 33%). Germ cell aplasia (Sertoli-cell-only syndrome) was found in 28 cases (15.1%). Tubular atrophy was the dominant lesion in 5 cases (2.7%). Inflammatory change without other histologic abnormalities was seen only in 1 biopsy (0.5%). Further 13 specimens (7%) showed miscellaneous lesions, including one intratubular germ cell neoplasia. Retrospective histopathologic analysis revealed the coexistence of different basic lesions in 43 of our cases (21.7%). According to the novel requirements, pathologists should always report the presence of germ cell forms in the specimen, which are potentially suitable for fertilization. This is essencial because the new methods of testicular spermium extraction and intracytoplasmatic spermium injection offer the chance of assisted fertilization, even for some patients with smaller testicles and slightly elevated FSH levels.
