RESUMO
UNLABELLED: The aim of this study was to analyze the results of surgical and conservative treatment of non-refluxing POM. In the period 2000-2009, 45 children (52 ureters) were treated, the average age was 5.8 months (±10.33), 24 children (26 ureters) by surgery (I) and 21 children (26 ureters) by conservative means (II). The average follow-up period was 73.8 (±32.91) and 30.85 months (±23.1) resp. Urine examination, USG, DTPA99mTc, biochemical testing, micturating cystouretography in all patients were performed. Significant difference was present in the occurrence of hydronephrosis of 0th, 3rd and 4th grade, p10 mm, p<0.01; and in the occurrence of normal and prolonged time T ½, p<0.01. The health condition was adjusted in 13 (54.20 %), improved on DTPA99mTc in 5 (20.85 %), non-improved in 3 (12.50 %), deteriorated in 1 (4.15 %) and unknown in 2 (8.3 %) patients. In the IInd group a significant difference was in case of occurrence of hydronephrosis of 0th, 2nd and 3rd grade, (p<0.01, or p=0.037 and p=0.011) and in occurrence of normal ureter, with ureter 0-5 mm and dilated ureter 5-10 mm, p<0.01. The condition at the end of the follow-up period was assessed DTPA99mTc as adjusted in 11 (52.39 %) patients, improved in 6 (28.57 %), unimproved in 3 (14.28 %) and no patient was assessed as having deteriorated and unknown in 1 (4.76 %). CONCLUSION: In patients with an impaired separate kidney function, early surgical treatment helps to minimize damage to the kidney function and prevents future complications (Tab. 6, Fig. 3, Ref. 32).

OBJECTIVE: To determine new data related to the expression of caspase 1, superoxiddismutase and calretinin in the placenta and basal decidua in preeclampsia. MATERIAL AND METHODS: Placental and basal decidua samples from 9 preeclamptic and 9 normotensive controls were analyzed using expressions of caspase 1, superoxiddismutase and calretinin assessed by immunohistochemistry. RESULTS: Caspase 1 was expressed in placental syncythium in preeclampsia constantly, while in the control group the expression was weak or absent. In Langhans cells, in fetal sinusoidal capillary endothelia and in Hofbauer cells the expression was equal in both groups. Stronger expression was observed in stromal myofibroblasts in preeclampsia. In preeclampsia, expression of superoxiddismutase in syncythium, in Langhans cells and in decidual cells was weaker. Calretinin was not found in any placental structure. Sporadically, calretinin was expressed in the interstitial extravillous trophoblast cells, in decidual cells and in spiral arterioles in preeclampsia. CONCLUSION: The obtained morphological data correlating with some clinical and biochemical features contribute to understanding of the molecular background of preeclampsia etiopathogenesis.

PURPOSE OF THE INVESTIGATION: Description of precancerous lesions and kidney tumors developing in a patient with chronic uremia treated by long-term hemodialysis. MOST IMPORTANT METHODS: Light microscopy, polarization and immunohistochemistry with CK1/CK3, CK5/6, CK7, CK8, CK20, EMA, Renal cell, CD10, Ki-67, PCNA, p53 and E-cadherin antibodies were used. MAIN FINDINGS: After 11 years of hemodialysis treatment of end-stage diabetic nephropathy and chronic tubulointerstitial nephritis an urgent left-sided nephrectomy was performed because of pain and massive intrarenal bleeding. Biopsy revealed acquired cystic kidney disease associated with multiple precancerous lesions, several small papillary adenomas and a multifocal renal cell carcinoma with conventional and papillary structures with admixture of small foci of highly cellular sarcomatoid features. Severe vascular nephrosclerosis and uremic oxalosis were additional findings. The upper pole of the kidney was massively hemorrhagic. PRINCIPAL CONCLUSIONS: This case illustrates the association of chronic renal insufficiency, uremic oxalosis, long-term hemodialysis, acquired cystic kidney disease and development of variable precursor intratubular and intracystic lesions progressing to several papillary adenomas and multifocal renal cell carcinomas with variegated microscopic structures in one kidney.

Autofluorescence bronchoscopy (AFB) has been shown to be sensitive to detect preneoplastic lesions in central lung airways system. In early stages of carcinogenesis, up-regulation of cyclooxygenase (COX)-2, Ki67 and/or increased angiogenesis may play a role by promoting the proliferation of tumoral cells and their resistance to apoptosis, as well as angiogenesis, tumor cell invasion and setting up of the metastatic process. The present study compared the expression of proliferative (COX-2, Ki67 and PCNA) and angiogenic markers (CD34 and NG2) between preneoplastic bronchial squamous dysplasia lesions and invasive squamous cell carcinoma. Biopsies obtained during AFB [preneoplastic lesions: low-grade (lesions up to moderate dysplasia), n=13; high-grade lesions (severe dysplasia), n=12] and surgical specimens (resections of bronchogenic carcinoma, n=11) were stained with COX-2, Ki67, PCNA, CD34 and NG2 monoclonal antibodies. Microvessel density (MVD) was analysed based on anti-CD34 immunostaining. Lesions were positive for COX-2 in 12 out of 25 preneoplastic lesions, and in 10 out of 11 invasive carcinomas (p=0.025). In preneoplastic lesions, the mean percentage of Ki67 positive cells was lower compared to invasive carcinomas (37.4+/-5.8 versus 58.6+/-8.4%, p=0.043). In addition, significant differences in MVD were observed between preneoplastic and NSCLC specimen [35.3 (25.9, 61.9) versus 22.1 (20.1, 32.6), p=0.016]. No differences were observed in the mean percentage of PCNA or NG2 positive cells between preneoplastic lesions and invasive carcinomas. Findings of the present study indicate that increases in COX-2 and Ki67 expression may be associated with the development of bronchogenic carcinomas and possibly with acquisition of an invasive phenotype. In contrast, increased CD34 expression in preneoplastic lesions suggests that increased MVD may represent an early marker of lung carcinogenesis.

Solitary fibrous tumors of the pleura are rare malignant pathological findings, accounting for only 5% of all pleural neoplasms. Clinical manifestations are very unspecific and over 50% of the cases are asymptomatic. The commonest clinical symptoms include cough, pains, dyspnoea, fever and weight loss. The recommended diagnostic methods include chest x-ray, CT and MRI imaging and positrone emission tomography. The CT-assissted puction biopsy yield is less than 50%. The authors present a case review of a 58-year-old female with a history of dyspnoea. Her chest x-ray and CT examination suggested a large cystoid lesion in the right hemithorax, with extensive dystelectasis of the right lung lobe. Functional pulmonary examination confirmed severe gas transfer dysfunction, with diffusion lung capacity of 47% of the normal. Stenosis of the right middle and lower lobar bronchus resulting from extramusral pressure was detected on bronchoscopy. The authors performed right-sided thoracotomy and removed an encapsulated solid tumor measuring 24 x 16 x 13.5 cm and weighting 2850 grams from the thoracic cavity. Benign solitary fibrous tumor was diagnosed on histology. The postoperative course was complicated by bleeding into the pleural cavity, which was managed conservatively and did not require subsequent surgical revision. The patient was released for home care in a good condition. The aim of the study is to draw attention to this tumorous disorder of the pleura - the solitary fibrous tumor.

BACKGROUND: The majority of cases of nephrotic syndrome in children is corticosensitive, however in some individuals aggressive cytotoxic therapy is necessary. Cyclosporin A and cyclophosphamide are widely used; however their relative effectiveness in maintaining remission of childhood nephrotic syndrome remains controversial. METHODS AND RESULTS: Effectiveness of long-term cytotoxic therapy (mean follow-up 7.4 years) in 63 children (mean age 6.19 +/- 4.30 years) with nephrotic syndrome was retrospectively analyzed; 14 patients suffered from corticosensitive, 33 from corticodependent and 16 from corticoresistant nephrotic syndrome. Corticotherapy alone was used in 15 patients (23.8%), cyclophosphamide was added in 27 (42.9%) and cyclosporin A in 38 cases (60.3%), while 17 patients (27%) were on both immunosuppressive agents. 84% children relapsed within 24 months after cessation of cyclosporin A. In 8 corticoresistant nephrotic syndrome patients (61.5%) from 13 children treated with cyclosporin A no remission occurred, in 5 children (38.5%) was remission obtained within 10 weeks, however in 4 of them relapsed disease during cyclosporin A therapy. 19 (70.4%) of 27 patients on cyclophosphamide therapy were in remission, in 8 of them (42.1%) even 2 years after cyclophosphamide therapy. CONCLUSIONS: Cyclophosphamide therapy of childhood nephrotic syndrome is more effective in maintaining long-term remission than cyclosporin A treatment.

An episode of gastroenteritis triggered severe necrosis of all extremities in a previously asymptomatic male. Hepatic and renal involvement were also manifest, while the hematological picture was one of thrombotic microangiopathic hemolytic anemia. Antiphospholipid antibodies were negative. He responded well to a combination of plasma exchange, anticoagulation (heparin), parenteral steroids, and antibiotics, as well as vasodilators (prostacycline) and hyperbaric oxygen, but died because of a cerebral hemorrhage. The differential diagnosis included thrombotic thrombocytopenic purpura/hemolytic-uremic syndrome, or seronegative catastrophic antiphospholipid (Asherson's) syndrome. The dangers of administering such a combination of therapies with anticoagulation, as well as vasodilatation (prostacycline) and hyperbaric oxygen, are highlighted by the case report and emphasized.

Actinomycosis is an infrequent chronic progressive granulomatous and suppurative disease caused by Actinomyces israelii, a natural inhabitant of the gastrointestinal tract. We report a rare case of a 68-year-old man with primary endobronchial actinomycosis who presented in the emergency respiratory ward with massive hemoptysis and dyspnea. An urgent fiberoptic bronchoscopy revealed hypertrophic mucosa and a narrowed lingular bronchus with a pale extruding exophyt. Diffuse bleeding from the mucosa adjacent to the exophyt was present. Histopathologic evaluation revealed chronic inflammation with abscess formation and clusters of Actinomyces colonies. Therapy with clindamycin maintained for 7 weeks prevented recurrence of the disease. In the light of our case and the review of literature we conclude that early recognition of primary endobronchial actinomycosis associated with hemoptysis and proper antibiotic treatment are essential to prevent undesirable complications including unwarranted surgery (Fig. 2, Ref. 30).

Fifty lung cancer samples (41 non-small cell lung cancer-NSCLC and 9 small cell lung cancer-SCLC) were immunohistochemically analyzed for lung resistance-related protein (LRP) and multidrug resistance-associated protein 1 (MRP1) expressions which were then correlated with histopathological subtype of the tumor. To detect these proteins, monoclonal antibodies LRP-56 and MRPm6 were used. NSCLC samples were divided into two groups, adenocarcinomas (17 samples) and squamous cell carcinomas (24 samples). Four categories of LRP and MRP1 quantity were distinguished: +++ = high level--90--100% of positive cells, ++ = lower level--10--90% of positive cells, + = low level--up to 10% of positive cells, - = negative cells--0% of positive cells. Within the NSCLC group the most samples (36/41) had the similar level of LRP and MRP1. Significantly higher expression of both proteins was observed in the adenocarcinomas in comparison with squamous cell carcinomas. The lowest positive staining for LRP and MRP1 proteins has been found in SCLC. It is suggested that our finding can confirm the overall empirical clinical knowledge about much higher chemosensitivity of untreated SCLC comparing to NSCLC.

In certain primary and metastatic malignant melanomas diagnostic problems may arise due to their cytologic features and/or absence of synthesis of melanin. As the "classic" combination of S-100 protein and HMB-45 may occasionally fail to stain cells of malignant melanoma, we have tested a series of commercially accessible antibodies which were so far not compared by other authors in the three most frequent subtypes of this tumor. In surgical specimens from 104 cutaneous malignant melanomas (40 nodular melanomas, 46 superficially spreading malignant melanomas and 18 lentigo maligna melanomas) the staining intensity and the proportion of neoplastic cells stained with antibodies to S-100 protein, HMB-45, NKI/C3, NKI/beteb, MART 1 (Melan A), KBA 62 and Mitf was semiquantitatively analysed. The use of this group of antibodies against melanoma-associated antigens revealed it to be a favourable supplement for the bioptical or cytological diagnosis of malignant melanoma in case the traditional/conventional combination of S-100 protein and HMB-45 antibody fails. According to the authors' experience the antibody against KBA 62 has shown to be the most effective antibody followed by the antibodies against MART-1 (Melan A) and NKI/C3.

AIM: To report a series of six cases of thyroid haemangiosarcoma (HAS) from a non-Alpine region. METHODS AND RESULTS: The patients were four females and two males, aged 54-81 years (average 68 years). The tumours presented as large haemorrhagic masses (diameter 40-70 mm, average 56 mm) with extensive necrosis. Histologically, they were composed of polymorphous epithelioid cells with vesicular nuclei and abundant eosinophilic cytoplasm with occasional intracytoplasmic lumina. Mitotic activity was high. Tumor cells expressed vimentin (6/6), CD31 (6/6), FVIII (5/6), CD34 (2/6), and cytokeratins (5/6). One tumour (1/6) over-expressed p53 protein in more than 20% of cells. Ultrastructurally, Weibel-Palade bodies were present (4/6). Clinical follow-up of four patients (range 3-24 months, median 9 months) showed that two of them have died of the disease 0.5 and 3 months after diagnosis, one died of unrelated causes (with 24 months' uneventful follow-up) and one is alive 21 months after operation with no evidence of disease. CONCLUSIONS: Although thyroid HAS is usually regarded as an extremely aggressive neoplasm with a dismal prognosis similar to anaplastic carcinoma, one of our cases suggests that HAS can behave in a less aggressive way. The morphological, immunohistochemical and ultrastructural findings support the hypothesis that thyroid HAS is a distinct entity, unrelated to other thyroid malignancies.

Expression of LRP--lung resistance-related protein was analyzed by immunohistochemical staining with monoclonal antibody LRP-56 in 30 specimens (10 from normal colorectal tissue and 20 from colorectal carcinoma). All normal tissue samples were LRP positive. Strong LRP staining was seen in the surface epithelium and upper parts of the crypts. Similarly, colorectal carcinomas demonstrated strong staining for LRP/MVP. Staining pattern of cytoplasm of carcinoma cells was the same as in the normal mucosa. The overexpression of LRP in the colorectal carcinoma may play a role in the process of carcinogenesis or be a marker of an aggressive phenotype. It seems, the high value of LRP is a predictor of response to chemotherapy and prognoses in various tumor types. (Fig. 7, Ref: 18.).

Mediastinal cysts, described also as homoplastic dysembryomas, account for 20% of mediastinal lesions. There are bronchogenic, oesophageal, gastrogenic and enterogenic, pericardial, non-specific cysts and cystic lymphangiomas. The authors present 6 patients with mediastinal cysts from a total number of 96 patients with mediastinal tumours subjected to surgery during a 14-year period (from Jan. 1 1987 to Dec. 31 2001). The group comprised 5 adults and one child. In four patients the authors selected thoracotomy as the route of access to the mediastinum, in one instance total sternotomy and once upper partial sternotomy. The cysts were removed as a whole. Histological examination revealed in four patients the diagnosis of a bronchogenic cyst, once a connective tissue cyst with respiratory epitheliumm and once a cyst lined with squamous epithelium. The postoperative course was in all patients free from complications. In the conclusion the authors emphasize the importance of complete removal of mediastinal cysts as relapses occur if part of the secretory eoithelium is not removed.

Previously unreported histological and immunohistochemical features of collagenous spherulosis in an epithelial-myoepithelial carcinoma found in an 80-year-old woman are described. The multinodular tumor located in the right parotid gland was completely removed surgically. No local recurrence of the tumor appeared during the 22-month period of periodic checkups. This is believed to be the first report on collagenous spherulosis in an epithelial-myoepithelial carcinoma of the salivary gland. Different immunohistochemical characteristics of epithelial and myoepithelial neoplastic cells were found very useful for their analysis namely in parts of the tumor where one cell type greatly predominated (e.g. clear cell-type predominance). The double staining of histological sections can in this sense be recommended for the differentiation from other clear cell tumors of salivary glands allowing the correct categorization of the neoplasm.

Based on a review of archival autopsy protocols an analysis of the frequency of pulmonary thrombembolism in consecutive autopsy material is presented. The study interval for the analysis was oriented to the period between the years 1949-2000. Our analysis has shown a gradual progression of incidence of pulmonary thrombembolism, as demonstrated in relative figures. The applied preventive measures against the development of thrombosis during hospitalization have not substantially contributed to decreasing its frequency, what is not in accord with some recent observations from other countries.

The paper presents a retrospective analysis of 20 patients with acute ethylene glycol intoxication who were treated from 1972 to 2001 in the Dialysis Centre of the IVth Medical Clinic and from 1997 at the L. Pasteur Nephrological Clinic of the Faculty Hospital and Safarík Medical Faculty in Kosice. The ethylene glycol intoxication was manifested by neurological symptoms, extreme metabolic acidosis, acute toxic hepatitis and acute renal failure. Laboratory examination revealed oxaluria in 17 patients and leukocytosis in all patients. Percutaneous renal biopsy was made for differential diagnostic or forensic reasons in the convalescent stage of acute renal failure in 6 patients. In the treatment of ethylene glycol intoxication the authors used ethyl alcohol as an antidote: in the first four patients administered by the i.v. route, in the remaining patients in dialyzation solution. Extreme metabolic acidosis improved in 15 patients after bicarbonate haemodialysis. Concomitant application of haemoperfusion over active charcoal during the first haemodialysis in four patients led to a potentiated effect on the uraemic syndrome. Conservative and extracorporeal elimination treatment of ethylene glycol intoxication succeeded in 16 patients (80%). According to the authors' experience early and fractionated application of bicarbonate haemodialysis with 100 mg% concentration of ethylalcohol in the dialysis solution is the method of choice in the treatment of ethylene glycol intoxication.

A large trichinellosis outbreak in the Slovak Republic caused by the species Trichinella britovi and affecting 336 people also affected a pregnant woman. The mother was infected in the 10th week of pregnancy and was treated with mebendazole. On her own request abortion was performed in the 22nd week of pregnancy. Medium IgM and high IgG anti-Trichinella antibody titres were found. The placenta, body cavities liquid, tissues and organs of the foetus contained 0.02-30 larvae per gram of tissue, measuring 0.68 +/- 0.05-1.17 +/- 0.07 mm, with blurred inner structure. Immunocytochemical examination identified Trichinella larvae that infected the foetus in the early stage of development.
