| ABSTRACT This study presents the density, taxonomic composition, spatial and temporal distribution of fish larvae in the Gulf of Guayaquil, as well as the relationship with some physical-chemical variables. Samples were collected at 16 stations, taken in the first nautical mile of the external and internal estuary of the gulf, located in front of the province of Guayas and northwest of the island of Puná, during June to December 2012. Surface trawls were carried out with a simple conical network (mesh eye: 300 μm; mouth diameter: 0.3 m; length: 1.2 m). Temperature, salinity, and transparency were measured before each drag. Significant differences were detected between zones, registering higher temperatures, lower salinity, and transparency in the interior... |

| Women living in Latin American countries bear a disproportionate burden of cervical cancer, a condition caused by infection with the human papillomavirus (HPV). We performed a study in Santa Elena, Guayas (currently Santa Elena Province), Ecuador, to determine how often HPV could be detected in women attending a private cancer screening clinic. Participants underwent a Pap test, and vaginal and cervical swabs were performed for HPV testing by the polymerase chain reaction (PCR). Each participant completed a verbally administered survey. The mean age of 302 participants was 37.7 years (range 18 to 78 years). The majority of cervical and vaginal specimens contained sufficient DNA to perform PCR. Overall, 24.2% of the participants had either a cervical or... |

| The relationship between human papillomavirus (HPV) and oropharyngeal squamous cell carcinoma has been established. However, data from Ecuador is limited. The objective of this study was to characterize HPV infection in Ecuadorian patients with tongue cancer. Fifty-three patients with tongue cancer treated at the tertiary referral center Sociedad de Lucha Contra el Cancer (SOLCA), Guayaquil, between 2006 and 2011 were identified. Linear Array® HPV genotyping was used to identify the presence and types of HPV on formalin-fixed paraffin-embedded biopsy samples from these patients with tongue cancer. HPV was identified in 42% (n=22) and high-risk (HR) HPV in 17% (n=9), with 18 different HPV types identified. The most common types were the HR HPV 33 (14%) and... |
