Hyperhomocysteinemia, MMPs and Cochlear Function: A Short Review.

Hyperhomocysteinemia (HHCY) has been demonstrated to affect cochlear microvasculature as well as cochlear epithelial cells directly, with a resultant alteration of the expression of matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs). Hence, ascertaining the optimum concentration of MMPs and TIMPs in the cochlea could help to inhibit hearing loss due to HHCY by the administration of appropriate MMP inhibitors, Since infections/inflammations as well as ototoxic antibiotics have a similar mechanism of otic pathology, the cochlear damage they cause could also be similarly prevented.

Olanzapine vs. Risperidone in Schizophrenia: A Cross-sectional Comparison of Quality of Life of Caregivers.

In schizophrenia, efficacy of antipsychotic therapy might be better measured by quality of life (QoL) of caregiver, due to less reliability of patient's account and greater burden of management on caregiver. Hence, we compared QoL of the primary caregiver of schizophrenics prescribed either olanzapine or risperidone. In a cross sectional analytical study, caregivers of 120 schizophrenic patients' on either olanzapine or risperidone filled the WHOQOL-BREF questionnaire containing physical, psychological, social and environmental domains.
