Searches related to schizophrenia and bipolar disorder were limited to children and adolescents. The bibliographies of the retrieved articles were hand-checked for additional relevant studies. The epidemiology, phenomenology, and treatment of EOSS and pedBP, and olanzapine’s pharmacology are reviewed. Studies of olanzapine treatment in youth with EOSS and pedBP are examined.

Results:

Olanzapine is efficacious for EOSS and pedBP. However, olanzapine is not more efficacious than risperidone, molindone, or haloperidol in EOSS SNX-5422 and is less efficacious than clozapine in treatment-resistant EOSS. No comparative trials have been done in pedBP. Olanzapine is associated with weight gain, dyslipidemia, and transaminase elevations in youth. Extrapyramidal symptoms, neuroleptic malignant syndrome, and blood dyscrasias have also been reported but appear rare.

Conclusions: The authors conclude that olanzapine should be considered a second-line agent in EOSS and pedBP due to its risks for significant weight gain and lipid dysregulation. Awareness of the consistent weight and metabolic changes observed in olanzapine-treated youth focused attention on the potential long-term risks of atypical antipsychotics in youth.”
“Objective

The round window membrane (RWM) is increasingly becoming a target for amplification using active

middle ear implants. However, the current strategy of using available transducer tips may have negative consequences for the RWM. We investigated the microanatomy of the RWM to establish a basis for the design of the transducer tip for the RWM driver.

Study Design

Using the guinea pig as an animal PLX4032 concentration model, microcomputed tomography (mu CT) and white light interferometry were used to study the topography of the RWM and RW niche (RWN). The curvatures of the RWM surface were calculated using the topography data.

Main Outcome Measures

The 3-dimensional structure of the scala tympani terminal, saddle-shaped surface topography, and surface curvature were

determined.

Results

The size of the scala terminal was approximated as an ellipse for which the major and minor axes were 1.29 and 0.95 mm. The average minimum and maximum radii of curvature around the center selleck of RWM were -0.44 and +0.70 mm along the minor and major axis.

Conclusion

The microanatomies of the RWM and RWN have important implications for the design of the transducer tip to maximize energy transfer while minimizing its distortion and permanent disruption. Our results suggest that the size of the transducer tip should be smaller than the minor axis of the scala terminal to avoid collision with the RWN. The driver should be designed to conform to the topography and radius of curvature of the center portion of the RWM, which for a guinea pig is 0.44 mm.”
