In México, tuberculosis patients are successfully treated with 1 g/day for over 6 months. Ototoxicity is often seen as a consequence of prolonged treatment with aminoglycosides. In young people STP damages the vestibule of the ear; in elder patients it diminishes hearing and balance. These effects are due to streptidine, a metabolite of STP produced in elder patients and detected in blood by liquid chromatography. On occasion, sudden deafness is established after only a short treatment period as the result of the presence of a single nucleotide mutation in the mitochondrial 12S rRNA gene. In patients with this polymorphism, aminoglycosides produce a stereotypic conformation similar to the bacterial 16S rRNA thus inhibiting the synthesis of proteins. Many aminoglycoside-sensitive mutations have been described in several ethnic groups, causing sudden deafness. We started similar studies in Mexican individuals, treated or not with an aminoglycoside, to determine whether similar alterations could be detected. To date in over 60 individuals analyzed we found only one case of polymorphism in a streptomycin treated patient. We developed a simple method to identify such mitochondrial gene in a larger population to make recommendations to use an alternative treatment which do not cause ototoxicity in the mutation bearing patient.</p>","PeriodicalId":20701,"journal":{"name":"Proceedings of the Western Pharmacology Society","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30507699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we review the medical literature over the last four decades to both quantitatively and qualitatively determine the adverse effects of ocular drugs and ocular toxicity of non-ocular drugs. A systematic bibliographic review of the literature was performed with the following terms: \"drug treatment\", \"drug therapy\", \"ocular adverse effects\", \"ocular side effects\", \"ocular toxicity\", \"systemic side effects\", \"systemic adverse effects\", \"systemic toxicity\", \"ocular drug\" and \"ophthalmic drug\" using the Boolean operators or, and, not. Searches focused on: (1) Ocular side/adverse effects of ophthalmic drugs; (2) Ocular side/adverse effects of systemic drugs; (3) Systemic side/adverse effects of ophthalmic drugs. PubMed was used to perform searches. Limits included: species, human and field tag, abstract/title, dates from 01/01/1971 to 31/12/2010. A sub-selection of references was made by discarding articles that were irrelevant for the topics listed above. Adverse effects of alpha2-adrenergic agonists, beta-adrenergic antagonists, quinine derivatives and antituberculosis agents appear in the literature throughout the period of the review. Adverse effects of newer drugs such as amiodarone, phosphodiesterase 5 inhibitors, antiepileptics, tamoxifen, and its interactions have been published principally in the last two decades.

A total of 50 patients with chronic lumber discogenic pain and radiculopathy were enrolled in this study and were randomized into two groups. Group 1 (n=26) underwent first time, single-level lumber discectomy at either L3-4, L4-5, or L5-S1 using the Stryker Disc Dekompressor for aspiration of disc material and Group 2 (n=24) received epidural steroid/local anesthetic injection. Data on patient demographics, operative time, length of hospitalization, incidence of postoperative complications, analgesic usage and postoperative complications were obtained. For short-term evaluation of the outcome in the two patient groups, the Visual Analogue Scale (VAS) from 0-10 for back pain and radicular pain were obtained preoperatively, 24 hr and 1-6 wk postoperatively. Also, the straight leg raising test (SLRT) was performed and recorded. A significant decrease in the radicular pain scores and an increase in SLRT degrees with a decrease in the back pain scores was seen in the disc Dekompressor group with minimal incidence of postoperative complications. In the epidural injection group, the back pain scores were significantly decreased postoperatively while the radicular pain and the SLRT degrees were insignificantly changed 24 hr postoperatively and at wk 6. We conclud that when standardized patient selection criteria are used, the disc DeKompressor is a safe and more effective treatment for radicular pain of discogenic origin than epidural injection with steroid/local anesthetic.

Ten microliters of PRP or PPP were placed into aluminum pans for DSC with or without activation by epinephrine (5.0 microM) or CaCl2 (50 microM). To avoid a spontaneous activation of platelets samples were kept frozen, after a 5 min period of stabilization, 5 microl of aggregation-inducing agent was added. Scans were initiated at a -12 degrees C after stabilization, with an increase of a 5 degrees C/min to a maximum of 60 degrees C. The experiments were performed on a TA Differential Scanning Calorimeter (New Castle, DE, USA).
