Background: Four measles cases in Canada and one in the United States are linked to international importation of measles in Playa del Carmen, Quintana Roo, Mexico. Objective: To describe characteristics of transmission and not spillover to local population in Mexico. Material and Methods: The outbreak investigation was based on active search of cases and in the rapid monitoring of vaccination coverage in children aged 1 - 7 years old. Laboratory confirmation by Enzyme-Linked Immunosorbent Assay (ELISA) and molecular detection by Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) assay in throat swab and urine were done. Results: One transmission chain with three generations of cases was identified. The primary case was a 9-year-old boy who was infected in Wales, UK. His sisters aged 7 and 15 years old respectively, were the first generation of cases in Mexico. The second generation was related to the imported cases, and affected two Canadian tourists and an American woman aged 39 years old. A third generation occurred in Canada and affected an infant of 15 months of age and his sister aged 4 years old. The genotype D8 which was circulating in UK was identified in these patients. One probable case was detected in Quintana Roo, but was discarded by laboratory testing. The coverage with at least one dose of Measles-Mumps-Rubella (MMR) vaccine ranged from 95% to 99.5%. Conclusion: International travelers with no history of vaccination are at risk of acquiring measles even in countries that have interrupted endemic transmission. The high immunization coverage of measles containing vaccine could explain the absence of cases in Mexican population. Highlights: Multinational measles outbreak in a country without endemic transmission. The findings exhibit the importance of immunization in international travelers in the post-elimination era.

Sensory denervation with capsaicin reduces ovarian follicular development and delays the onset of puberty in guinea pigs

引用

Advances in Reproductive Sciences 2013年第3期1卷 29-37页

作者： Victorino Alatriste irma Herrera-Camacho María I. martínez Ilhicamina D. Limón Oscar González-Flores Félix Luna Centro de Investigación en Reproducción Animal UAT-CINVESTAV Tlaxcala México Centro de Química ICUAP Puebla México Departamento de Farmacia FCQ-BUAP Puebla México

Introduction: It has been documented that mammalian ovaries receive sympathetic, parasympathetic and sensory nerve fibers. The aim of this work was to investigate the effects of sensory denervation with capsaicin at the first vaginal opening (FVO) on follicular development and the expression of TRPV1 receptors in ovary cells as well as in the dorsal root ganglia (DRGs) and lumbar dorsal spinal cord neurons of guinea pigs. The DRGs and lumbar dorsal spinal cord neurons serve as a nerve connection from the ovaries to the CNS. Materials and Methods: Female guinea pigs received a subcutaneous injection of capsaicin (30 mM) at 10 days of age (P10), while control animals were injected with vehicle. Using light microscopy, we counted healthy preantral follicles (HPF), healthy antral follicles (HAF), atretic preantral follicles (APF), and atretic antral follicles (AAF) in the ovaries at the FVO, and the numbers of TRPV1-positive cells were counted in the ovarian follicles, DRGs, and lumbar dorsal spinal cord (L2-L4) neurons by immunohistochemistry. Results: Guinea pigs treated with capsaicin showed a significant delay of FVO in comparison with the control animals (36 vs. 44 days). In the ovaries, the number of preantral and antral follicles decreased significantly. Additionally, the number of TRPV1-positive thecainterstitial cells of the antral follicles was reduced significantly, and the number of TRPV1-positive neurons in the DRGs and lumbar dorsal spinal cord (L2-L4) decreased. Thus, we showed that TRPV1 receptors throughout the sensory fibers modulate ovarian follicular development and the onset of puberty in guinea pigs. Conclusion: Sensory denervation decreases ovarian follicular development and delays the onset of puberty of guinea pigs. Our data support the idea that through TRPV1 receptors, ovarian afferent fibers sense local stimuli that are sent to the CNS.
