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.

Objective: This study elaborated on the clinical experience of patients who underwent urologic management due to urologic complications after receiving a total hysterectomy at a regional hospital. Materials and methods: A total of 696 female patients received the four types of total hysterectomy including total abdominal hysterectomy, transvaginal hysterectomy, lapaparoscopic hysterectomy or robotic hysterectomy for variant gynecologic pathologies. Only 22 cases (3.2%) had urologic procedures performed during or after the operations from 2012/1/1 to 2016/6/30. Results: Of the 22 cases, thirteen (1.9%) received a series of conservative managements only, including cystoscopy, ureteroscopy, endoscopic ureterotomy, ureteral catheterization or double J stenting during the follow-up period. Nine more complicated cases (1.3%) eventually had definitive management, including repair of the urinary bladder rupture, repair of the vesicovaginal fistula, ureteroureterostomy or ureteroneocystostomy. However, five of these nine cases had both conservative and definitive management. The mean delay interval between the initial management and gynecologic procedure was 19.3 days. For definitive management and the gynecologic procedure, the period was 52.8 days. Conclusions: Compared to previous studies, the incidence of urologic injuries following a total hysterectomy in our hospital was similar. From the paper review, it seems early recognition does not improve the outcome but we found a 100% good outcome in patients with definitive management.
