Transient exposure of brown trout embryos from fertilization until hatch (70 days) to 17β-estradiol (E2) was investigated. Embryos were exposed to 3.8 and 38.0 ng/L E2 for 2h, respectively, under four scenarios: (A) exposure once at the day of fertilization (0 days post-fertilization, dpf), (B) once at eyeing stage (38 dpf), (C) weekly exposure until hatch or (D) bi-weekly exposure until hatch. Endpoints to assess estrogen impact on embryo development were fertilization success, chronological sequence of developmental events, hatching process, larval malformations, heart rate, body length and mortality. Concentration-dependent acceleration of development until median hatch was observed in all exposure scenarios with the strongest effect observed for embryos exposed once at 0 dpf. In addition, the hatching period was significantly prolonged by 4-5 days in groups receiving single estrogen exposures (scenarios A and B). Heart rate on hatching day was significantly depressed with increasing E2 concentrations, with the strongest effect observed for embryos exposed at eyeing stage. Estrogenic exposure at 0 dpf significantly reduced body length at hatch, not depending on whether this was a single exposure or the first of a series (scenarios A and D). The key finding is that even a single, transient E2 exposure during embryogenesis had significant effects on brown trout development. Median hatch, hatching period, heart rate and body length at hatch were found to be highly sensitive biomarkers responsive to estrogenic exposure during embryogenesis. Treatment effects were observable only at the post-hatch stage.

OBJECTIVES/HYPOTHESIS Study of the clinical evolution of a primary ear, nose, and throat infection complicated by septic thrombophlebitis of the internal jugular vein. STUDY DESIGN Retrospective case-control study. PATIENTS AND METHODS From 1998 to 2010, 23 patients at our institution were diagnosed with a septic thrombosis of the internal jugular vein. Diagnostics included microbiologic analysis and imaging such as computed tomography, magnetic resonance imaging, and ultrasound. Therapy included broad-spectrum antibiotics, surgery of the primary infectious lesion, and postoperative anticoagulation. The patients were retrospectively analyzed. RESULTS The primary infection sites were found in the middle ear (11), oropharynx (8), sinus (3), and oral cavity (1). Fourteen patients needed intensive care unit treatment for a mean duration of 6 days. Seven patients were intubated, and two developed severe acute respiratory distress syndrome. An oropharynx primary infection site was most prone to a prolonged clinical evolution. Anticoagulation therapy was given in 90% of patients. All 23 patients survived the disseminated infection without consecutive systemic morbidity. CONCLUSION In the pre-antibiotic time, septic internal jugular vein thrombophlebitis was a highly fatal condition with a mortality rate of 90%. Modern imaging techniques allow early and often incidental diagnosis of this clinically hidden complication. Anticoagulation, intensive antibiotic therapy assisted by surgery of the primary infection site, and intensive supportive care can reach remission rates of 100%. LEVEL OF EVIDENCE 3b. Laryngoscope, 2014.
