Silver, M.D.3 1 The Neurosciences Institute and Advanced Imaging Research Center Department of Neurology, Albany Medical College, Albany, NY 2 Department of Psychology, Union College , Schenectady, NY 3 Samuel S. Stratton, VA Medical Center, Albany, NY Using single voxel or multi-voxel magnetic resonance spectroscopy MRS ; , this research is designed to develop neurobiochemical biomarkers of noise-induced tinnitus within the auditory centers of the human brain in the left and right hemispheres. Being able to detect and measure metabolites in the millimolar range, such as N-acetyl aspartate NAA ; , choline Cho ; , creatine Cr ; , glutamate Glu ; , gamma-aminobutyric acid GABA ; and or glycine Gly ; , we can begin to understand if and or how tinnitus and hearing loss, either alone or in combination, alters the neurobiochemical environment of these auditory cortical areas. Two groups of individuals matched for age, gender, and hearing loss will be studied: Group 1 will include individuals with noise induced hearing loss with tinnitus and Group 2 will include individuals with noise induced hearing loss without tinnitus. Controlling for hearing loss is an imperative core issue that has confounded many previous studies in this area, making interpretation of results difficult if not impossible. Additionally, using voxel-based morphometry VBM ; , we will determine the extent to which structural brain anatomy in the form of grey and or white matter volumes are different between groups and possibly correlated with the MRS. Taken together, MRS and VBM has the potential to enhance our understanding of tinnitus that is currently unavailable by any other methodologies. If successful, this conceptual framework will add to the available body of tinnitus research by: 1 ; contributing to understanding underlying mechanisms, 2 ; aid in developing structural and or neurobiochemical models of noise-induced tinnitus, 3 ; help in monitoring treatment options, 4 ; aid in diagnosis, and 5 ; act as a segue towards a cure. Indeed, MRS in particular is uniquely positioned as a research tool between the domains of neurochemistry and structural brain imaging that is well suited for studying humans in a non-invasive manner, for example, levofloxacin prophylaxis.
Many cases of community-acquired pneumonia are caused by Streptococcus S. ; pneumoniae, which usually responds to antibiotics known as beta lactams which include penicillin ; . However, other important causes of CAP, particularly in younger people, are atypical bacteria, which respond to macrolides either erythromycin, clarithromycin, or azithromycin ; or newer quinolones. Such quinolones include levofloxacin Levaquin ; , gatifloxacin Tequin ; , gemifloxacin Factive ; , and moxifloxacin Avelox ; . In most cases, unlike macrolides, the newer quinolones are also active against penicillin-resistant S. pneumoniae. ; The standard treatment, then, for community-acquired pneumonia in most patients is a combination of a beta-lactam and a macrolide or quinolone. Oral antibiotics are generally sufficient for patients whose CAP is mild enough to be treated at home. Intravenous antibiotics are required for hospitalized patients with CAP. [For details on any or all the antibiotics in this section, see Box Antibiotic Classes.]. Levofloxacin used treated certain bacterial infectionsRichard GA, et al.19 Two randomized, multicenter trials of levofloxacin vs. ciprofloxacin vs. lomefloxacin in acute pyelonephritis. Ics with a -lactam moiety in their chemical structure. Clavulanate is a -lactamase inhibitor; therefore, amoxicillin-clavulanate is effective against lactamaseproducing organisms eg, -lactamase producing strains of H influenzae and M catarrhalis ; . The mechanism of S pneumoniae resistance is different from that of -lactamase production. Streptococcus pneumoniae resistance occurs because of an altered penicillin binding site. Amoxicillin-clavulanate offers no advantage over amoxicillin alone in the treatment of infections caused by resistant strains of S pneumoniae. As previously discussed, higher routine doses of amoxicillin may be needed in certain circumstances. A common recommendation is to double the usual dose. With currently available formulations of amoxicillin-clavulanate, 2 prescriptions are required 1 for amoxicillin and the other for amoxicillin-clavulanate ; to achieve a higher dose of amoxicillin without increasing the dose of clavulanate, a gastrointestinal mucosal irritant. The complexity of such a regimen may compromise patient compliance. The newer macrolides clarithromycin and azithromycin ; may be acceptable second-line agents, specifically in patients who are allergic to penicillin. Resistance among the pneumococci to these agents is increasing.50, 96 Breakpoints for resistance by the NCCLS are 1 g mL for erythromycin and clarithromycin and 2 g mL for azithromycin, although the NCCLS recommends that erythromycin antimicrobial susceptibility test results can predict the activities of other macrolides. Erythromycin-resistant strains are resistant to clarithromycin, azithromycin, and usually penicillin.102 Haemophilus influenzae, which is susceptible in vitro to azithromycin, may survive in an infected fluid because of lower extracellular concentration of the antibiotic.103 The mechanisms of action of macrolide resistance may be enzymatic deactivation or active efflux of the antibiotic across the bacterial cell membrane or ribosomal alterations.104, 105 Clindamycin can be used for infections caused by S pneumoniae, but it does not eradicate H influenzae or M catarrhalis and is consequently inappropriate empirical therapy for sinusitis. The newer fluoroquinolones -- levofloxacin, moxifloxacin, and gatifloxacin -- have good in vitro activity against S pneumoniae, including penicillin-resistant isolates, and excellent tissue penetration into the sinuses. The first-line use of the fluoroquinolones should be restricted to patients with moderate-to-severe infections or recent antibiotic failures. There are differences between the in vitro activities of the different fluoroquinolones against S pneumoniae.106, 107 and miconazole.

KPMA has created a "leadership network" through use of email to help us stay informed of new legislative and administrative changes and any other issues which require coordinated action. It is also a tool to use for improving communication between us and decreasing the isolation individual members sometimes experience. You can be added to this email list by emailing Theresa Walton at waltonkpa aol . As part of the KMA KPMA fall meeting training is planned on effective advocacy with elected officials. I encourage each of you to attend this important training and take the opportunity to network with each other for potential sharing of solutions to some of these problems. I also ask that each of you working with Medicaid and experiencing problems with pre-authorization keep us informed by email and fax. The Psychiatric Medicaid Advisory Committee formed through efforts of KPMA and Sheila Schuster ; has been meeting regularly with officials from the Medicaid office to resolve ongoing problems. We especially need copies of any rejections of prescriptions by First Health and reports of problems with the call center. Another threat highlighted at the APA annual meeting is the success of psychologists receiving prescribing privileges in two states, New Mexico and Louisiana. I would like to set a goal that every Kentucky Legislator be contacted by a KPMA member from their district before the next legislative session to educate them about this issue and to prevent such legislation in this state. If you have any other suggestions, questions or issues, please contact me at doctombscs aol or 502-228-3775. I attribute many of these current problems to the growth of for-profit national healthcare and development of an increasingly complex "bureaucratic medical system" to oversee a fragmented and uncoordinated heath system which doesn't even provide universal healthcare coverage to all. This reminds me of one of my favorite movies from 1976, Networks. It is a satire on the problems of TV Broadcast news when control is shifted to a multinational company, which is driven by blindly ambitious TV programmers and corrupt businessmen interested in greed rather than focusing on basic human values. The scene that is absolutely chilling is when the anchorman, played by Peter Finch, who is being fired during his last broadcast ends his tirade dealing with his own sense of frustration and futility by instructing his viewer to "Go to the window and shout as loud as you can: I'm mad as hell and I'm not going to take it anymore." The scene ends with the camera showing people across the country Please See Presidents Message Page 9.
