Abstract
The sterile inflammatory response mediated by Toll-like receptors (TLRs) 4 and 9 is implicated in the massive hepatic damage caused by acetaminophen (APAP)-overdose. There is a crosstalk between TLR-dependent signaling with other intracellular kinases like phosphatidylinositol 3-kinases (PI3Ks). Nevertheless, the detailed role of PI3Kα is still unknown in hepatic sterile inflammation. Accordingly, the effect of the novel PI3Kα inhibitor alpelisib was investigated in the setting of APAP-driven sterile inflammation in the liver. This was examined by pretreating mice with alpelisib (5 and 10 mg/kg, oral) 2 h before APAP (500 mg/kg, i.p.)-intoxication. The results indicated that alpelisib dose-dependently lowered APAP-induced escalation in serum liver function biomarkers and hepatic necroinflammation score. Alpelisib also attenuated APAP-induced rise in cleaved caspase 3 and proliferating cell nuclear antigen (PCNA) in the liver hepatocytes, as indices for apoptosis and proliferation. Mechanistically, inhibition of PI3Kα by alpelisib limited APAP-induced overproduction of the pro-inflammatory tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 in the blood circulation via switching off the activation of several signal transduction proteins, including extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), signal transducer and activator of transcription-3 (Stat-3), glycogen Synthase Kinase (GSK)-3β and nuclear factor (NF)-κB. Alpelisib also impaired APAP-instigated immune cell infiltration in the liver via reducing systemic granulocyte/macrophage-colony stimulating factor (GM-CSF) release and reversed APAP-induced abnormalities in the systemic and hepatic levels of the anti-inflammatory IL-10 and IL-22. In conclusion, selective modulation of the PI3Kα activity by alpelisib can hinder the inflammatory response and infiltration of immune cells occurring by APAP-hepatotoxicity.

Abstract
Acute respiratory distress syndrome (ARDS) is a life-threatening disorder with a high rate of mortality. Complement activation in ARDS initiates a robust inflammatory reaction that can cause progressive endothelial injury in the lung. Here, we tested whether inhibition of the lectin pathway of complement could reduce the pathology and improve the outcomes in a murine model of LPS-induced lung injury that closely mimics ARDS in human. In vitro, LPS binds to murine and human collectin 11, human MBL and murine MBL-A, but not to C1q, the recognition subcomponent of the classical pathway. This binding initiates deposition of the complement activation products C3b, C4b and C5b-9 on LPS via the lectin pathway. HG-4, a monoclonal antibody that targets MASP-2, a key enzyme in the lectin pathway, inhibited lectin pathway functional activity in vitro, with an IC50 of circa 10nM. Administration of HG4 (5mg/kg) in mice led to almost complete inhibition of the lectin pathway activation for 48hrs, and 50% inhibition at 60hrs post administration. Inhibition of the lectin pathway in mice prior to LPS-induced lung injury improved all pathological markers tested. HG4 reduces the protein concentration in bronchoalveolar lavage fluid (p<0.0001) and levels of myeloid peroxide (p<0.0001), LDH (p<0.0001), TNFα and IL6 (both p<0.0001). Lung injury was significantly reduced (p<0.001) and the survival time of the mice increased (p<0.01). From the previous findings we concluded that inhibition of the lectin pathway has the potential to prevent ARDS pathology.

Abstract
Inflammation has been convicted of causing and worsening many liver diseases like acute liver failure, fibrosis, cirrhosis, fatty liver and liver cancer. Pattern recognition receptors (PRRs) like TLRs 4 and 9 localized on resident or recruited immune cells are well known cellular detectors of pathogen and damage-associated molecular patterns (PAMPs/DAMPs). Stimulation of these receptors generates the sterile and non-sterile inflammatory responses in the liver. When these responses are repeated, there will be a sustained liver injury that may progress to fibrosis and its outcomes. Crosstalk between inflammatory/fibrogenic-dependent streams and certain tyrosine kinases (TKs) has recently evolved in the context of hepatic diseases. Because of TKs increasing importance, their role should be elucidated to highlight effective approaches to manage the diverse liver disorders. This review will give a brief overview of types and functions of some TKs like BTK, JAKs, Syk, PI3K, Src and c-Abl, as well as receptors for TAM, PDGF, EGF, VEGF and HGF. It will then move to discuss the roles of these TKs in the regulation of the proinflammatory, fibrogenic and tumorigenic responses in the liver. Lastly, the therapeutic opportunities for targeting TKs in hepatic inflammatory disorders will be addressed. Overall, this review sheds light on the diverse TKs that have substantial roles in hepatic disorders and potential therapeutics modulating their activity.

Abstract
Endothelin-1 (ET-1) contributes to the development of kidney diseases. However, the underlying molecular mechanism is largely undefined. Here we sought to investigate the potential role of ET-1 receptors, ETA and ETB in the regulation of increased glomerular permeability and underlying signaling pathways post-ET-1 infusion. Male Sprague-Dawley rats were infused with ET-1 (2 pmol/kg per minute, i.v.) for four weeks, and the effect on glomerular permeability to albumin (Palb) and albuminuria was measured. The selective ROCK-1/2 inhibitor, Y-27632, was administered to a separate group of rats to determine its effect on ET-1-induced Palb and albuminuria. The role of ETA and ETB receptors in regulating RhoA/ROCK activity was determined by incubating isolated glomeruli from normal rats with ET-1 and with selective ETA and ETB receptor antagonists. ET-1 infusion for four weeks significantly elevated Palb and albuminuria. Y-27632 significantly reduced the elevation of Palb and albuminuria. The activities of both RhoA and ROCK-1/2 were increased by ET-1 infusion. Selective ETB receptor antagonism had no effect on the elevated activity of both RhoA and ROCK-1/2 enzymes. Selective ETA receptor and combined ETA/ETB receptors blockade restored the activity of RhoA and ROCK-1/2 to normal levels. In addition, chronic ET-1 infusion increased the levels of glomerular inflammatory and fibrotic markers. These effects were all attenuated in rats following ROCK-1/2 inhibition. These observations suggest that ET-1 contributes to increased albuminuria, inflammation, and fibrosis by modulating the activity of the ETA-RhoA/ROCK-1/2 pathway. Selective ETA receptor blockade may represent a potential therapeutic strategy to limit glomerular injury and albuminuria in kidney disease.

Abstract
Cisplatin (CIS) is a potent anticancer drug that is used in the treatment of different types of cancer. Owing to its serious side effects, its clinical use is considerably limited. AIMS This study was mapped to investigate the potential effects of desloratadine (DES) against CIS-induced nephrotoxicity and testicular injury. MAIN METHODS DES (5 and 10 mg/kg) was orally administered for 10 days, and CIS was injected once (10 mg/kg, i.p.) in adult male rats on day 9 to induce both renal and testicular toxicity. KEY FINDINGS DES significantly attenuated CIS-induced alterations in histopathology and biomarkers. DES resulted in a significant reduction in serum levels of creatinine (Cr), urea, and blood urea nitrogen (BUN), in addition to a marked decrease in urinary levels of albumin and total protein. Additionally, DES efficiently reinstated the oxidative balance by preventing the elevation of malondialdehyde (MDA) and enhancing superoxide dismutase (SOD) activity, and increasing glutathione (GSH) levels. Moreover, DES produced a profound decrease in renal and testicular levels of nucleotide-binding domain-(NOD) like receptor 3 (NLRP3), interleukin (IL)-1β, and caspase-1 when compared to the CIS group. Furthermore, DES significantly decreased CIS-induced elevation in toll-like receptor 4 (TLR4), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-κB) levels in both renal and testicular tissues. SIGNIFICANCE DES can be used as adjuvant therapy with CIS in cancerous cases, pending further clinical studies.

Abstract
The cardiotonic digoxin has been recently shown to possess an anti-inflammatory potential in numerous metabolic and inflammatory disorders. However, data about digoxin’s impact in the setting of acute liver injury and sterile inflammation are still limited. Here, we investigated the potential effect of digoxin pretreatments (0.25 and 0.5 mg/kg, oral) on the severity of acute hepatotoxicity in mice challenged with a single dose of diethylnitrosamine (DN; 150 mg/kg, intraperitoneal) for 24 h. Our results indicated that digoxin pretreatments dose-dependently mitigated DN-induced rise of hepatocellular injury parameters and necroinflammation scores. Digoxin, particularly at dose of 0.5 mg/kg, boosted the number of PCNA positive hepatocytes, leading to improvement of the reparative potential in hepatocytes of DN-intoxicated livers. Digoxin’s ameliorative effect on DN-hepatotoxicity coincided with (i) lowering the increased hepatic production and release of the proinflammatory mediators IL-17A, IL-1β and TNF-α, and (ii) impeding the attraction and infiltration of monocytes to the liver, as denoted by decreasing serum MCP-1 and F4/80 immunohistochemical expression. These effects were attributed to reducing DN-induced activation of NF-κB and overexpression of CD98 in the liver. Meanwhile, DN elicited a decline in the hepatic production and release of the anti-inflammatory cytokines IL-22 and IL-6, which was intensified by digoxin, especially at a dose 0.5 mg/kg. In conclusion, digoxin conferred liver protection against DN-insult by impairing the overproduction of proinflammatory cytokines and infiltration of inflammatory cells to the liver.

Abstract
Acetaminophen (APAP)-induced hepatotoxicity comes among the most frequent humans' toxicities caused by drugs. So far, therapeutic interventions for such type of drug-induced toxicity are still limited. In the current study, we examined the influence of capmatinib (Cap), a novel c-Met inhibitor, on APAP-induced hepatotoxicity in mice when administered 2 h prior, 2 h post and 4 h post APAP-challenge. The results revealed that Cap administration significantly attenuated APAP-induced liver injury when administered only 2 h prior and post APAP-administration. Cap hepatoprotective effect was mediated by lowering the excessive formation of lipid peroxidation and nitrosative stress products caused by APAP. Besides, Cap attenuated APAP-induced overproduction and release of proinflammatory mediators like TNF-α, IL-1β, IL-17A, IL-6, and MCP-1. Cap treatment also led to avoidance of APAP-subsequent repair by abating APAP-induced elevation of hepatic IL-22 and PCNA expressions. In conclusion, c-Met receptor inhibition may be a potential strategy for alleviating APAP-hepatotoxicity, especially when administered in the early phase of intoxication.

Abstract
BACKGROUND Pirfenidone (PFD) is an orally active antifibrotic agent that has anti-inflammatory activity in diverse animal models. Its effect against acute pancreatitis (AP) has not been elucidated. Hence, the present investigation was carried out to assess the potential protective role of PFD against l-arginine-induced AP in mice. METHODS AP was induced in adult male Swiss albino mice via intraperitoneal injections of l-arginine (4 g/kg, twice each 1 h apart). PFD (250 mg/kg, orally) was administered one day before and on the day of l-arginine challenge. Twenty-four hours after l-arginine injection, the severity of AP was evaluated using biochemical and histological analyses. Indices of oxidative stress, inflammation and apoptosis were evaluated using ELISA and immunohistochemistry (IHC). RESULTS PFD suppressed the development of l-arginine-induced AP as revealed by the improvement of histopathological lesions of pancreatic specimen and the significant reduction of serum amylase and lipase levels. Notably, PFD reduced the lipid peroxidation and enhanced the antioxidants such as reduced glutathione (GSH) and superoxide dismutase (SOD) in pancreatic tissue. Importantly, PFD suppressed AP-associated elevation of inflammatory cytokines along with depression of nuclear factor kappa-B (NF-κB) immuno-expression in pancreatic tissue. Lastly, PFD efficiently ameliorated AP-induced elevation of the pro-apoptotic protein (Bax) and increased AP-induced reduction of the anti-apoptotic protein (Bcl2). CONCLUSIONS PFD protected against l-arginine-induced AP in mice through anti-oxidative, anti-inflammatory and anti-apoptotic properties.

Abstract
Febuxostat, a highly potent xanthine oxidase inhibitor with an antioxidant effect, inhibits elevated xanthine oxidase, leading to reduction of reactive oxygen species and oxidative stress, the main causes of vascular inflammation in hyperlipidemia. The aim of this study was to test the potential antioxidant and anti-inflammatory effects of febuxostat and (or) stopping a high-fat diet on the biochemical parameters in rabbits with hyperlipidemia induced by a high-fat diet. Male New Zealand rabbits were distributed into 3 groups: a normal control group fed standard chow for 12 weeks and 2 other groups fed a high-fat diet with 1% cholesterol for 8 weeks, and then shifted to standard chow for 4 weeks. During the last 4 weeks, one high-fat diet group received 0.5% carboxymethyl cellulose, whereas the other group was treated with febuxostat (2 mg/kg per day p.o.). Febuxostat significantly lowered low-density lipoprotein cholesterol (“bad” cholesterol) compared to the untreated group (high-fat diet group). Febuxostat also displayed a potent anti-inflammatory and antioxidant activity by decreasing serum levels of lipid peroxidation index, proinflammatory cytokines, and enhancing antioxidant enzyme activity. Stopping the hyperlipidemic diet in the high-fat diet group did not show improvement. These findings indicate the antioxidant and anti-inflammatory effects of febuxostat that may be common mechanisms of the anti-hyperlipidemic effect of this drug. Stopping a hyperlipidemic diet without treatment is not sufficient once injury has occurred.

Abstract
Background/purpose Pristimerin (Pris) is triterpenoid compound with many biological effects. Until now, nothing is known about its effect on doxorubicin (DOX)-induced cardiotoxicity. Hence, this study investigated the impact of Pris on DOX-induced cardiotoxic effects. Materials and methods Rats were treated with Pris 1 week before and 2 weeks contaminant with repeated DOX injection. Afterwards, electrocardiography (ECG), biochemical, histopathological, PCR, and Western blot assessments were performed. Results Pris effectively alleviated DOX-induced deleterious cardiac damage. It inhibited DOX-induced ECG abnormities as well as DOX-induced elevation of serum indices of cardiotoxicity. The histopathological cardiac lesions and fibrosis were remarkably improved in Pris-treated animals. Pris reduced hydroxyproline content and attenuated the mRNA and protein expression of the pro-fibrogenic genes. The antioxidant activity of Pris was prominent through the amelioration of oxidative stress parameters and enhancement of antioxidants. Furthermore, Pris enhanced the activation of nuclear factor-erythroid 2 related factor 2 (Nrf2) signaling pathway as it increased the mRNA and protein expression of Nrf2 and Nrf2-dependent antioxidant genes (GCL, NQO1, HO-1). Additionally, the anti-inflammatory effect of Pris was obvious through the inhibition of mitogen activated protein kinase (MAPK)/nuclear factor kappa-B (NF-kB) signaling and subsequent inhibition of inflammatory mediators. Conclusion This study provides evidence of the cardioprotective activity of Pris which is related to the modulation of Nrf2 and MAPK/NF-kB signaling pathways.

Abstract
Pristimerin (Pris) is a triterpenoid derivative obtained from Celastraceae and Hippocrateaceae families. This compound has been extensively tested for its potent anti-cancer activity against different types of tumors. However, its effects against acute lung injury (ALI) remain to be investigated. This study explored the efficacy of Pris to protect against lipopolysaccharide (LPS)-induced ALI and its possible pathways. Results have shown that Pris possesses potent protective activity against LPS-induced acute lung damage. It significantly decreased pulmonary edema as presented by significant decrease in lung W/D ratio and in protein content. Pris attenuated LPS-induced inflammatory cell infiltration into the lung tissue and suppressed the activity of myeloperoxidase in lung. LPS-induced histopathological lesions were significantly improved via Pris pretreatment. Pris exhibited not only inhibition of LPS-induced oxidative stress, but also enhancement of the suppressed antioxidant capacity of the lung tissue. The anti-inflammatory activity of Pris against LPS-induced ALI was clearly evident via attenuation of the levels of pro-inflammatory cytokines namely, tumor necrosis factor-α and interleukin-6. Similarly, Pris inhibited LPS-induced elevation of pro-apoptotic protein, Bax, and caspase-3. Pris also increased the diminished level of Bcl2 induced by LPS. Collectively, Pris exerted protective activity against LPS-induced ALI via anti-oxidant, anti-inflammatory and anti-apoptotic pathways.

Abstract
Pristimerin (Pris) is bioactive natural quinonoid triterpene that has anti-inflammatory and anti-cancer activities. Meanwhile, its effect against hepatitis needs to be elucidated. This investigation aimed to evaluate the ability of Pris to protect against autoimmune hepatitis (AIH). A mouse model of AIH was established using single concanavalin A (Con A) intravenous injection. Mice were treated with Pris at two different doses (0.4 and 0.8 mg/kg) for 5 days prior to Con A challenge. Markers of hepatic injury, oxidative, inflammatory, and apoptotic damage were estimated. Results have revealed that Pris pretreatment ameliorated Con A-induced hepatic damage. There was decrease in the elevated serum indices of hepatic damage (ALT, AST, ALP, and LDH) and improvement of the histopathological picture of the liver. Pris effectively decreased Con A-induced neutrophil infiltration into the hepatic tissue as presented by amelioration of the level and immuno-expression of myeloperoxidase (MPO). Additionally, Pris attenuated Con A-induced increase in CD4+ T-cells in hepatic tissue. Lipid peroxidation was significantly depressed simultaneously with enhancement of the antioxidant capacity in Pris pretreated animals. Pris also enhanced nuclear factor erythroid 2-related factor 2 (Nrf2) mRNA expression and its binding capacity. In addition, Pris increased mRNA expression of heme-oxygenase-1 (HO-1) and restored its normal level. Furthermore, Pris decreased the level and immuno-expression of nuclear factor kappa-B (NF-κB) as well as the downstream inflammatory cascade (TNF-α, IL-6, and IL-1β). Finally, Pris showed inhibitory effect on Con A-induced apoptotic alteration in liver as it decreased the mRNA expression and levels the apoptotic markers (Bax and caspase-3) and increased mRNA expression and level of the anti-apoptotic protein (Bcl2). In conclusion, this study demonstrates the potent hepatoprotective efficacy of Pris against Con A-induced hepatitis which may be related to anti-oxidative, anti-inflammatory, and anti-apoptotic pathways. Pris could serve as a new candidate for the management of hepatitis.

Abstract
Sodium valproate (VP) is an important antiepileptic drug, although it can produce deleterious hepatotoxic reactions. Diallyl trisulfide (DATS) is the principle component of garlic oil that possesses antioxidant properties. This study explored the potential hepatoprotective activity of DATS against VP-induced hepatic damage and its underlying mechanisms. In addition, the study assessed the effect of DATS on VP antiepileptic activity. Rats were given DATS once daily at two different doses along with VP for 2 weeks. Results have shown the ability of DATS to counteract VP-induced hepatic damage as it decreased elevated serum transaminases (aspartate aminotransferase and alanine aminotransferase) and alkaline phosphatase. Liver histopathology indicated that DATS preserved the hepatic structural integrity and protected against VP-induced hepatic steatosis and necro-inflammation injury. DATS ameliorated VP-induced oxidative stress and increased the antioxidant capacity of the liver. Immunohistochemical analysis showed activation of nuclear factor kappa-B along with high expression of cyclo-oxygenase-2 (COX-2) upon VP administration. This was accompanied by overproduction of proinflammatory mediators (TNF-α, IL-1β, IL-6). Tracing the apoptotic pathway, VP administration induced marked apoptosis using TUNEL staining. Furthermore, VP-treated animals exhibited high immunoexpression of Bax protein and increased levels of Bax and caspase-3 while level of Bcl2 was significantly decreased in hepatic tissue. However, DATS simultaneous treatment counteracted all of these molecular pathological changes. Using pentylenetetrazole (PTZ)-induced seizures model in mice, the effect of DATS on the anticonvulsant activity of VP was found to be positive, meaning that combination of DATS with VP can confer protection against VP-induced hepatic injurious effects through its antioxidant, antiinflammatory, and antiapoptotic properties without affecting VP antiepileptic activity.

Abstract
Background: Hypertrophic cardiomyopathy (HCM) is a genetic disease associated with risk of morbidity and sudden cardiac death. The prevalence, hypertrophy patterns, mode of presentations, and different ECG findings vary in different regions of the world. To date, no data is present regarding these variables in Qatar. Patients and Methods: A retrospective, cross sectional, descriptive analysis of all patients referred for echocardiography study at Hamad General Hospital, Qatar. The study period was from January 2008 till December 2010. Aims: To study 1) the prevalence of HCM, 2) the different patterns of hypertrophy, and 3) the clinical and ECG presentations in this population. Results: Out of the 29,286 cases evaluated, 38 patients were found to have HCM (0.13%). Their clinical, ECG, and echocardiography findings were analyzed. Mean age was 47 y, 35 males (92%) and 3 females (8%). Four patterns of hypertrophy were described; 17 (44.7%) had septal hypertrophy alone, 6 (15.8%) had septal and other segments hypertrophy but sparing the apex, 10 (26.3%) had apical segments along with any other segment hypertrophy, and 5 (13.2%) had apical hypertrophy alone. No obstruction was found in 19 (50%), left ventricular outflow (LVO) tract obstruction was found in 13 (34%), and mid cavity obstruction (MCO) in 6 (16%). Twenty one (55.3%) patients were referred because of chest pain, 15 (39.5%) with palpitations, 15 (39.5%) with shortness of breath, and 5 (13.2%) with syncope. Nine patients (23.7%) were asymptomatic and were referred because of cardiac murmur during routine examination. ECG evidence of LV hypertrophy was found in 29 (76.3%). Conclusion: The prevalence of HCM in our population group is 0.13% with a male predominance (12:1). There was a diversity of clinical presentation, ECG abnormalities and patterns of LV hypertrophy among HCM patients.

Abstract
BACKGROUND Epistaxis is the most common complication encountered during nasotracheal intubation (NTI) in children. The aim of this study was to test the efficacy of prophylactic intranasal admixture of xylometazoline and local anaesthetic gel in reducing epistaxis after NTI in children. METHODS Children presenting for dental procedures requiring NTI were randomly allocated into two groups: Group 1 (xylometazoline group, n=53) and Group 2 (control group, n=51). After sevoflurane inhalation induction, the more patent nostril in each subject was lubricated with lidocaine 2% (1 ml) jelly, followed by 0.6 ml of either xylometazoline hydrochloride 0.1% nasal drops (Group 1) or sodium chloride 0.9% (Group 2). The presence and extent of bleeding occurring during intubation, extubation, or both and navigability through the nasal passage were assessed. RESULTS The incidence and severity of bleeding were significantly reduced between the study group (7.5%) compared with the control group (27.5%; P<0.01). Navigability was similar in both groups. CONCLUSIONS Admixture of intranasal xylometazoline 0.1% drops and lidocaine 2% jelly reduced the incidence and severity of epistaxis after NTI in preschool children.

Abstract
OBJECTIVE To evaluate the outcome of patients with continent urinary diversions who had a solitary functioning kidney at the time of surgery. PATIENTS AND METHODS In all, 62 patients with continent urinary reservoirs and a solitary functioning kidney were reviewed (51 men and 11 women). The indications for surgery were bladder cancer in 54 and a contracted bladder in eight. The surgical procedures included an orthotopic ileal neobladder in 36 patients, a continent cutaneous ileal reservoir in 13 and rectal diversion in 13. Kidneys were evaluated using serum creatinine level, ultrasonography, intravenous urography and other radiological studies. RESULTS The follow-up was 6-173 months; 44 renal units (71%) remained stable during this period. Serum creatinine was increased in four patients with an orthotopic neobladder, with no evidence of obstruction or reflux, in one with preoperative renal impairment and one with voiding dysfunction, reflux and bacteriuria. Six renal units deteriorated because of uretero-intestinal strictures; of these patients, two were treated endoscopically, two with open ureteric reimplantation, one with conversion from a rectal reservoir to an ileal loop conduit, and one was maintained on JJ stenting. Six patients with a rectal diversion had renal deterioration because of chronic pyelonephritis. CONCLUSIONS A regular follow-up of renal function is mandatory in patients with a continent urinary diversion. Rectal diversion is associated with a higher risk of renal deterioration (54%) than are orthotopic (28%) and cutaneous reservoirs (8%).

Abstract
OBJECTIVE To evaluate our experience with men who underwent radical cystectomy and urethral Kock pouch construction between January 1986 and January 1996. PATIENTS AND METHODS Complications were classified as early (within the first 3 months after surgery) or late. Continence was assessed by interviewing the patient; they were considered continent if they were completely dry with no need of protection by pads, condom catheter or medication. The patients were followed oncologically and Kaplan-Meier survival curves constructed. Urodynamic studies were used to define the possible causes of enuresis. RESULTS Three patients died after surgery from pulmonary embolism. There were 67 early complications in 63 patients. The mean (SD) follow-up was 87.8 (49.1) months. There were 111 treatment failures from cancer; of these, four men only had an isolated local recurrence in the urethra. Late complications included 72 pouch stones in 55 patients, and 36 deteriorated renal units caused by reflux (17), uretero-ileal stricture (11), nipple valve eversion (four) or stenosis (four). Interestingly, 65 renal units that were dilated before surgery improved significantly afterward. Ileo-urethral strictures occurred in seven men and anterior urethral strictures in six. Nine patients were totally incontinent and two had chronic urinary retention. Daytime continence was complete in 94% of men, with nocturnal enuresis in 55; the latter had significantly more residual urine, and a higher amplitude and duration of phasic contractions. CONCLUSIONS Orthotopic bladder substitution after cystectomy for cancer is feasible, with good functional and oncological outcomes in properly selected patients. Nevertheless, the use of a hemi-Kock pouch is associated with many valve-related complications.

Abstract
OBJECTIVE To report on tumour angiogenesis and its relationship with morphological variables and prognosis in adenocarcinoma of the urinary bladder associated with schistosomiasis. PATIENTS AND METHODS Fifty-five vesical adenocarcinomas were evaluated from 30 men and 25 women (mean age 47.2 years, sd 8.7, range 30-65) who were followed up after radical cystectomy and urinary diversion for a mean (sd, range) of 61 (43.5, 2.7-159.5) months. Vessels were stained immunohistochemically using an antibody to the platelet endothelial cell-adhesion molecule CD31. Microvessels were counted in active areas of angiogenesis within the tumours (at x250) and the microvessel density (MVD) quantified using the mean of three counts. Treatment failure was defined as death from cancer or the development of local recurrence or distant metastasis. Kaplan-Meier survival curves and Cox's proportional hazard model were used to assess survival. RESULTS The overall 5- and 10-year survival rates were 57% and 51%, respectively. The presence of lymph node metastasis and high mean vascular density (> 26) were significantly associated with a poor prognosis. The 5-year survival for patients with negative lymph nodes was 66% while no patients with positive nodes survived for 5 years (P < 0.001); the survival was 72% for patients with a low MVD and 33% for those with a high MVD (P = 0.0016). From individual results plotted against vascularity in lymph node-negative patients, there was a significantly better outcome for those with a low MVD (< or = 26; P = 0.0099); this significance was maintained on multivariate analysis. However, there was no significant relationship between angiogenesis and the different clinicopathological factors apart from the grade (P = 0.03); tumour stage, grade and DNA profile had no significant effect on survival in these patients. CONCLUSIONS These findings suggest that assessing angiogenesis using the MVD provides an independent predictor of survival in patients with adenocarcinoma of the urinary bladder.

Abstract
PURPOSE We evaluated the urodynamic features of enuretic and continent patients with an orthotopic neobladder. MATERIALS AND METHODS Included in our study were 100 men with an orthotopic hemi-Kock or W neobladder and a minimum followup of 1 year. Of the patients 50 were completely continent day and night, and 50 had enuresis without evidence of an underlying organic etiology, such as stones, reflux or urethral stricture. RESULTS Univariate analysis showed significantly higher pressure and a larger volume of post-void residual urine in the men with enuresis. In addition, maximum urethral pressure, maximum flow and compliance were decreased in the enuretic group compared to the continent group. Multivariate analysis revealed that post-void residual urine volume, frequency and maximum amplitude of uninhibited contractions are the most critical parameters affecting nocturnal continence. CONCLUSIONS The cystometric parameters significantly associated with nocturnal enuresis in patients with an orthotopic reservoir are post-void residual urine volume, frequency and maximum amplitude of uninhibited contractions. Urethral pressure and flow parameters did not sustain significance on multivariate analysis.

Abstract
Urological complications in 211 consecutive primary and secondary cadaveric renal transplants, performed t our institution between March 1993 and December 1996, were encountered in 13 patients (6.2%). The complications included urine leakage in four cases (1.9%)., obstruction of the upper urinary tract in seven (3.3%), urethral strictures in two (1%) and stone formation in one. Successfully treated complications amounted to 86%. Associated infection and urinary leak resulted in the loss of two grafts.

Abstract
We reviewed the incidence and types of de novo malignancies which developed in 792 renal transplant recipients who received their grafts between 1979 and 1996 and followed up for an average period of 5.6 years. There were 56 malignant tumors detected in 54 patients, representing an overall incidence of 6.8%. These tumors occurred in a relatively young group of patients whose average age was 33.4 years at the time of transplantation and 40 years at the time of diagnosis of malignancy. The average latency period between transplantation and malignant disease was 7.4 years for solid tumors and 16 months for Kaposi's sarcoma. Tumors included 39 Kaposi's sarcomas, four malignant lymphomas, three hepatomas, two bladder cancers, one renal cell carcinoma of the allograft, two colorectal cancers, two thyroid cancers, one adenocarcinoma of unknown primary, one nasopharyngeal carcinoma and one leiomyosarcoma of the uterus. Kaposi's sarcoma was the most common malignancy and comprised 70% of all tumors in this study. It is imperative for renal transplant recipients to have diligent follow-up at regular intervals for early detection of cancer.

Abstract
OBJECTIVES To characterize adenocarcinomas of the urinary bladder by their DNA profiles and their proliferative properties. METHODS Primary nonurachal adenocarcinomas, found in 93 patients with bilharzial bladder carcinomas, were studied using DNA flow cytometry. Tumor ploidy and S-phase fraction were related to tumor grade, stage, cell type, and lymph node status. RESULTS Aneuploidy with high S-phase fractions, found in 90% of the tumors, demonstrates the high malignancy potential of these tumors, the majority of which were found to be muscle-infiltrative. There were no relationships between ploidy or S-phase fraction and tumor grade and stage. Lymph node metastases, present in 24% of the 93 patients, were found exclusively in nontetraploid aneuploid tumors with high S-phase fractions exceeding 100%. Paraffin-embedded tissues compared with fresh material gave the same information on ploidy, whereas bladder washing did not provide adequate information. CONCLUSIONS The high aggressiveness of adenocarcinomas in the biharzial bladder is confirmed and can be explained by their proneness to develop gross chromosomal aberrations combined with high cell proliferation.

Abstract
Prostate glands from 150 patients with carcinoma of the bilharzial bladder who underwent cystoprostatectomy were studied histopathologically by step sections. Prostatic urethral involvement by urothelial carcinoma was noted in 13 out of 96 (13.5%) and 5 out of 40 (12.5%) squamous and transitional cell tumors, respectively. None of the 12 adenocarcinomas and the two undifferentiated tumors showed involvement. Prostatic urethral involvement was as high as 19% in basal tumors and 26.7% in multifocal tumors compared to only 6.5% when the tumors occupied the bladder body. There was a significant increase in the incidence of prostatic urethral involvement from 9.5 to 35% when the prostate gland was involved. Prostate gland was involved in 20 out of 150 (13.3%). The bladder tumor was basal and infiltrating the prostate in 18 such cases. Seminal vesicles were infiltrated in 6 cases from the adjacent basal bladder tumors. We conclude that patients with basal or multifocal tumors are risky regarding bladder substitution and we recommend routine diagnostic transurethral prostatic biopsies and frozen sections from the site of urethral transection during cystoprostatectomy whenever bladder substitution controlled by the urethral sphincter is considered.

Abstract
Sixty eight infants and newborns were included in the present study being consisted of 55 cases with congenital anomalies and 13 cases of apparently healthy infants acting as controls. Three types of congenital anomaly cases were studied; 17 cases of microcephaly, 17 cases of cerebral palsy and 21 cases with jaundice. All serum samples were tested for cytomegalovirus IgM antibodies (CMV IgM) by microassay ELISA technique to explore the role of CMV infection in inducing congenital anomalies. Six out of the 68 serum samples were found to be positive for CMV IgM. Four of them were detected among the congenital cases (5 our to 55; 7.3%), while 2 cases were among the controls (2 out of 13; 15.4%). The microcephalic group showed 5.9% positivity (one out of 17). The jaundiced infants showed 14.3% positivity (3 out of 21), while all the cerebral palsy cases were negative for CMV IgM. Such a high percentage of CMV IgM in the control group may be attributed to asymptomatic infection, with liability for long term sequelae, particularly hearing loss or ocular abnormalities by 2 years of age. So, continuous follow-up of such asymptomatic cases is essential to control any possible congenital abnormality as early as possible.

Abstract
Intravenous digital subtraction angiography (IV-DSA) combined with excretory urography (IVU) were utilized to study the renal anatomy of 1000 potential live-kidney donors. In the entire series, 712 donors (71.2%) had bilateral single renal arteries, whereas 255 (25.5%) had unilateral multiple, 26 (2.6%) had bilateral multiple, and 7 (0.7%) had unilateral hypoplastic or absent renal arteries determined by IV-DSA. Major renal abnormalities that might be potentially significant for safe renal donation were detected in 76 donors (7.6%) by combined IV-DSA and IVU studies. In 10% of the potential donors, intraarterial digital subtraction angiography (IA-DSA) was required because of the equivocal results of IV-DSA. Of the 1000 potential donors, 700 underwent nephrectomy and the number of renal arteries at nephrectomy was compared with both IV-DSA and IA-DSA reports. Analysis of data revealed a sensitivity of 96% vs 95%, a specificity of 57% vs 75% and an overall accuracy 93% vs 90% for IV-DSA and IA-DSA, respectively, both IV-DSA and IA-DSA were accurate enough in identification of single renal arteries. However, the accuracy of IA-DSA was better than that of IV-DSA in visualization of double (84% vs 64%) and triple (66% vs 33%) renal arteries. It is concluded that IV-DSA combined with IVU is an effective technique for the evaluation of potential kidney donors. In cases where IV-DSA is equivocal, we recommend confirming IA-DSA.

Abstract
A urethral controlled bladder substitute was constructed from a detubularized, double folded ileal segment in 40 male patients following cystoprostatectomy for bladder cancer. For reflux prevention patients were prospectively randomized to receive either an intussuscepted nipple valve or the ureters were implanted by the Le Duc mucosal trough technique. All patients had normal upper tracts preoperatively. Mean patient age, performance status and stage of cancer were comparable in both groups. Patients were evaluated 6 to 18 months postoperatively. In addition to history taking, assessment included excretory urography, ascending cystography and voiding cystourethrography. During the observation period all patients with nipple valves had normal radiographic appearance of the upper tracts without evidence of reflux. On the other hand, following the Le Duc procedure 12 of 38 renal units (31%) showed evidence of radiographic dilatation. Of the 12 units 11 had stenotic ureters and 1 had reflux. We conclude that nipple valves are more effective in reflux prevention and protection of the upper urinary tract in patients for whom an ileal neobladder is indicated.

Abstract
Flow cytometric DNA analysis and ABO(H) cell surface antigen expression were studied in 46 patients with cystectomies for carcinoma of bilharzial bladder. The most significant prognostic indicators were the DNA index and the status of the pelvic lymph nodes at operation. Diploid tumors were associated with a low metastatic potential (7.7%) and a better five-year survival (54%) in contrast to aneuploid cases that had a higher metastatic potential (45.5%) and a low five-year survival (21%). The ABO(H) isoantigen status did not correlate with pathologic parameters or the clinical course of these invasive bilharzial bladder tumors as was previously reported.

Abstract
In 185 men a urethral Kock pouch was constructed as a bladder substitute after radical cystectomy for cancer. A total of 117 patients was followed for a minimum of 1 year and is fully evaluable. Of the patients 108 (92%) are completely continent during the day, while 85 (73%) are dry at night. Also, 8 patients had an excellent response to imipramine hydrochloride. Stability or improvement in the configuration of the upper tract was noted in 210 renal units (90%). A total of 24 renal units showed evidence of deterioration due to reflux (16) and an anastomotic stricture (8). Stability of the antireflux nipple valve was ensured by creation of a window in the mesentery of the corresponding bowel segment and by anchoring the valve to the wall of the pouch by an additional row of staples. On the basis of this favorable outcome the procedure is recommended for male patients for whom cystectomy is indicated and in whom the urethra can be preserved.

Abstract
Using adult mongrel dogs, the urodynamic characteristics of three types of ileal reservoirs were studied and compared. Segments of ileum of the same length were utilized to construct simple loop pouches (five dogs), DeKlerk pouches (five dogs) and Kock pouches (five dogs). Six to eight weeks after surgery, urodynamic evaluation was carried out. This included determination of the volume/pressure relationship and measurement of the contractions of the circular and longitudinal muscle fibers. Results indicate that the Kock pouch offers the best features in terms of the volume capacity, the volume/pressure relationship and contractile activity. Detubularization abrogated the muscle tone but it did not affect the phasic contractile activity of the circular muscle layer.

Abstract
To study the effect of the configuration of ileal reservoirs on the urodynamic features, 12 S bladders and 12 Kock pouches were compared. Volume capacity and pressure characteristics were studied 6 months postoperatively. The mean capacity of the reservoirs was 500 +/- 83 ml. for the S bladder and 536 +/- 56 ml. for the Kock pouch. The amplitudes of phasic contractions at 50%, 80% and 100% capacity were similar in both groups. However, the frequency of these contractions was higher in the S bladder. The intraluminal pressure at full capacity was 31 +/- 15 cm. water for the S bladder and 39 +/- 20 cm. water for the Kock pouch. The similar urodynamic features of the S and Kock pouches indicate their ultimate expansion into reservoirs of close physical characteristics and urodynamic behavior.

Abstract
The deoxyribonucleic acid patterns in lymph node metastases in relation to the degree of ploidy and proliferation in the primary bladder tumor were evaluated in 162 patients who underwent cystectomy for muscle invasive bladder carcinoma. The 34 diploid tumors had given rise to lymph node metastases in only 2 cases (6%), whereas 34% of the aneuploid tumors had metastasized. The frequency of lymph node metastases increased with the proportions of S-phase cells. In transitional cell carcinoma all tumors with a proportion of S-phase cells exceeding 20% had metastasized, while tumors with a proportion of S-phase cells between 10 and 20%, and less than 10% had metastases in 50 and 33%, respectively. The degree of ploidy of aneuploid tumors seems to be of importance for the potential to give rise to metastases, since the majority of metastatic tumors were in the triploid-tetraploid and hyperdiploid but not hypertetraploid regions. The degree of ploidy of lymph node metastases was in good agreement with that of the primary tumors.

Abstract
We studied 100 cases of squamous cell carcinoma of the bladder by flow cytometry after cystectomy. Tumors were classified according to the deoxyribonucleic acid profile into diploid or aneuploid. Proliferation of the tumors was assessed from the proportions of S-phase cells. The flow cytometric data were correlated to the histopathological stage and grade. Grade 1 tumors could be subdivided into diploid and aneuploid in 60 and 40% of the cases, respectively, while 95% of the grade 2 and all grade 3 tumors were aneuploid. Diploid tumors had low proliferation rates, while aneuploid tumors had significantly higher values. A high frequency of muscle invasive diploid squamous cell tumors was noted. Tumor heterogeneity was studied by comparing cell material from superficial and deep tumor areas, which were in agreement in 77% of the cases. By comparing biopsy material with that obtained by bladder washings, biopsy material yielded better information regarding deoxyribonucleic acid ploidy in half of the aneuploid tumors. These results indicate that flow cytometry offers an additional objective method to characterize squamous cell carcinoma.

Abstract
Using 11C labelled material, the diffusion of the hypoxic cell sensitizer misonidazole was tested in 19 patients with carcinoma of the bladder following its intravesical administration. Increasing concentration gradients were tested. Evidence was provided that a 20 ml solution containing 200 mmol/l of misonidazole is followed by high concentrations of the drug in the superficial as well as in deep parts of the tumour. The corresponding serum concentration was extremely low. It was concluded that this route of administration provides high local concentrations of the drug that may result in a significant therapeutic enhancement if utilized as an adjuvant to external irradiation.
