Main Outcome Measures: The main outcome measures https://www.selleckchem.com/products/pp2.html used were the differences between pretreatment and posttreatment pure-tone audiometry averages (PTAs) and speech discrimination scores (SDSs). Successful treatment was defined as a greater than 10 dB improvement in PTA and 15% in SDS. The final assessment of hearing was performed 3 months after completion of treatment.
Results:
Significant hearing recovery was observed in 31 (67.39%) of 46 cases, and in 24 (52.17%) of 46 control patients. Patients receiving combination therapy had a median improvement in PTA of 23.12 dB and a median increase in SDS of 32%. In the control group, the median hearing gain was 16.87 dB and 18%, respectively. The differences between the 2 groups were not statistically significant (p = 0.10 and p = 0.13). However, after performing a post hoc analysis by excluding individuals with profound hearing loss (PTA, > 90 dB), the combined treatment Duvelisib mouse group showed significant improvement compared
with the control group (p = 0.04). No serious complications or adverse reactions were reported.
Conclusion: The addition of intratympanic steroids to the conventional systemic steroid therapy may provide a safe and potentially effective therapeutic option in patients with mild-to-severe ISSNHL.”
“Purpose of review
Cell transplantation to restore liver function as an alternative to whole liver transplantation has thus far not been successful in humans.
Recent findings
Adult mature hepatocytes and various populations of liver progenitors and stem cells are being studied for their regenerative capabilities. Hepatocyte transplantation to treat metabolic deficiencies has shown promising early improvement in liver function; however, long-term success has not been
achieved. Liver progenitor cells can now be identified and were shown to be capable to differentiate into a hepatocyte-like phenotype. Despite evidence of mesenchymal stem cell fusion in animal models of BKM120 liver regeneration, encouraging results were seen in a small group of patients receiving autologous transplantation of CD133(+) mesenchymal stem cells to repopulate the liver after extensive hepatectomy for liver masses. Ethical issues, availability, potential rejection and limited understanding of the totipotent capabilities of embryonic stem cells are the limitations that prevent their use for restoration of liver function. The effectiveness of embryonic stem cells to support liver function has been proven with their application in the bioartificial liver model in rodents.
Summary
There is ongoing research to restore liver function in cell biology, animal models and clinical trials using mature hepatocytes, liver progenitor cells, mesenchymal stem cells and embryonic stem cells.”
