ABSTRACT

BACKGROUND: Vasitis is a rare condition that may be challenging for the clinical practitioner. Sometimes it is misdiagnosed as incarcerated inguinal hernia; thus, patients end up receiving unnecessary surgery. Compared with the traditional approach with only sonography, the more recent introduction of computed tomography in the diagnostic process has provided higher quality imaging and more detailed anatomy. Consequently, some urologists advocate the efficacy of computed tomography in the differential diagnosis of difficult cases. CASE PRESENTATION: We present the case of a 23-year-old male who suffered from right inguinal pain and swelling. His scrotum ultrasound showed multiple tubular structure dilatation within the subinguinal area and no testis torsion. The initial diagnosis was a right inguinal hernia. Computed tomography supported that initial diagnosis, and we presumed the lesion represented a herniation of the omentum with mesenteric vessels. Since there was a suspicion of hernia incarceration, the patient underwent diagnostic laparoscopy, which did not reveal herniation, but only erythematous reaction and swelling over the right spermatic cord. Following a final diagnosis of vasitis, he received empirical antibiotic treatment and his symptoms entirely resolved. CONCLUSIONS: Even though computed tomography can provide thorough imaging of the urogenital system, the contrast enhancement within vessels and inflammatory organs can still be misleading in the diagnostic process.


RéSUMé: CONTEXTE: La déférendite est. une maladie rare qui peut présenter des difficultés pour le praticien. Parfois, elle est. diagnostiquée à tort comme une hernie inguinale incarcérée; ce qui amène les patients à subir une intervention chirurgicale inutile. Par rapport à l'approche traditionnelle avec la seule échographie, l'introduction plus récente de la tomodensitométrie dans le processus diagnostique a fourni une imagerie de meilleure qualité et une anatomie plus détaillée. Par conséquent, certains urologues préconisent l'efficacité de la tomodensitométrie dans le diagnostic différentiel des cas difficiles. PRéSENTATION DU CAS: Nous rapportons le cas d'un homme de 23 ans qui souffrait d'une douleur et d'une tuméfaction inguinales droites. L'échographie du scrotum a montré une dilatation de multiples structures tubulaires dans la région subinguinale, sans torsion du testicule. Le diagnostic initial a été une hernie inguinale droite. La tomodensitométrie a confirmé ce diagnostic initial, et nous avons supposé que la lésion représentait une hernie de l'épiploon avec des vaisseaux mésentériques. Comme il y avait une suspicion d'incarcération de hernie, le patient a subi une laparoscopie diagnostique, qui n'a pas révélé de hernie, mais seulement une réaction érythémateuse et un gonflement du cordon spermatique droit. Après un diagnostic final de déférendite, le patient a reçu un traitement antibiotique empirique et ses symptômes ont été entièrement résolus. CONCLUSIONS: Même si la tomodensitométrie peut fournir une imagerie approfondie du système urogénital, l'amélioration du contraste dans les vaisseaux et les organes inflammatoires peut encore être trompeuse dans le processus diagnostique. MOTS-CLéS: Déférendite hernie inguinale incarcérée tomodensitométrie laparoscopie diagnostique.

ABSTRACT

The prevalence of human adenoviruses (HAdV) in river waters was investigated in this study. Water samples were collected from 13 rivers in Taiwan, concentrated, and assessed for the presence of HAdVs using nested polymerase chain reaction (PCR). Human AdV positive samples were then subjected to real-time PCR (qPCR) to quantify the viral genomes and further subjected to primer-based genotyping to identify the various serotypes present. For each water sample, several water quality parameters were evaluated, including heterotrophic plate count, total coliform, Escherichia coli, water temperature, pH, conductivity, and dissolved oxygen. Among the 13 rivers examined, four rivers (30.8 %) were found to contain HAdVs. The major genotype was F species HAdV serotype 41. The mean HAdVs concentrations ranged from 6.10 × 10(2) to 8.51 × 10(2) copies/L. No significant differences were observed between the presence of HAdVs, and all of the water quality parameters evaluated (heterotrophic plate count, total coliform, E. coli, water temperature, pH, conductivity, and dissolved oxygen). Given the potential health risks posed by the presence of enteric viruses in environmental waters, further assessment is desirable with respect to possible sources, virus transport, and survival of viruses in the aquatic environment.

ABSTRACT

BACKGROUND/PURPOSE: Cigarette smoking is the main risk factor for urothelial carcinoma of the bladder (UCB). Glutathione S-transferase omega 1 (GSTO1) and sulfotransferase 1A1 (SULT1A1) have been reported to be associated with the metabolism of polycyclic aromatic hydrocarbons (PAHs) and aromatic amines. The aim of the present study was to investigate the combined effects of polymorphisms in GSTO1 and SULT1A1 genes and cigarette smoking on UCB risk in a Taiwanese population. METHODS: A total of 300 patients with histopathologically confirmed UCB and 233 cancer-free controls were recruited from the Department of Urology of Tung's Taichung Metro Harbor Hospital and Taipei Medical University Hospital. A comprehensive interview was conducted to collect personal information, including demographic characteristics and cigarette smoking status. A multivariate-adjusted logistic regression was performed to estimate the risk of UCB. RESULTS: A significantly increased risk of UCB was observed in ever smokers [odds ratio (OR) = 2.3]. The Ala/Ala genotype of the GSTO1 gene and the Arg/Arg genotype of the SULT1A1 gene were associated with a significantly increased risk of UCB, with ORs of 1.8 [95% confidence interval (CI) = 1.2-2.6] and 2.1 (95% CI = 1.6-4.5), respectively. Significantly increased UCB risks were found in heavy smokers with the Ala/Ala genotype of the GSTO1 gene (OR = 4.2) and the Arg/Arg genotype of the SULT1A1 gene (OR = 6.8). Furthermore, a significant synergistic effect in an additive model (OR = 3.5) between the GSTO1 Ala/Ala genotype and the SULT1A1 Arg/Arg genotype on UCB risk was observed. CONCLUSION: The present study provided epidemiological evidence for a significantly increased risk of UCB in ever smokers with the Ala/Ala genotype of the GSTO1 gene and the Arg/Arg genotype of the SULT1A1 gene.

ABSTRACT

NAD(P)H: quinine oxidoreductase (NQO1) plays an important role in the metabolism of several carcinogens contained in cigarettes. Inducible nitric oxide synthase (iNOS) expression had been detected in urinary bladder tumors. The aim of this study was to investigate the interaction of iNOS and NQO1 on bladder cancer (BC) risk stratified by cigarette smoking status. METHODS: A total of 159 BC patients and 150 cancer-free controls were recruited from December 2003 to November 2004. Genotyping of NQO1 rs1800566 polymorphism and iNOS (CCTTT)n pentanucleotide repeat polymorphism was determined using the polymerase chain reaction-restricted fragment length polymorphism and sequencing method. The odds ratio and 95% confidence interval (CI) were calculated as a measure of the joint effect of NQO1 rs1800566 and iNOS (CCTTT)n polymorphisms on BC risk among cigarette smokers. RESULTS: Compared with study participants carrying the C/C genotype of NQO1 gene, those with C/T and T/T genotypes had a significantly increased BC risk of 1.8 (95% CI = 1.1-2.9). Among cigarette smokers, those who carried the 12-repeat allele of iNOS (CCTTT)n polymorphism had a significantly increased BC risk of 2.7 (95% CI = 1.0-6.7). Furthermore, a significant combined effect of the C/T and T/T genotypes of NQO1gene and the 12-repeat allele of iNOS (CCTTT)n repeat polymorphism on BC was found among cigarette smokers (odds ratio = 4.4, 95% CI = 1.3-14.9). CONCLUSION: Our findings suggest that a significant combined effect of NQO1 C/T and T/T genotypes and the 12-repeat allele of iNOS (CCTTT)n polymorphism on BC exists, especially in those with the habit of cigarette smoking.
