Item Exacerbation of myasthenia gravis by alendronate(Springer London Ltd, 2014-07-05) Kesikburun, Serdar; Güzelküçük, Ümüt; Alay, Semih; Yavuz, Ferdi; Tan, Arif Kenan; YokMyasthenia gravis is an important indication for the long-term prescription of corticosteroids. We present a patient with myasthenia gravis who had worsening of symptoms associated with the use of alendronate. A 24-year-old patient with myasthenia gravis had been administered oral systemic corticosteroid (deflazacort 40 mg/day) for 3 years in order to control his myasthenic symptoms. One year earlier, his lumbar spine bone mineral density was decreased. He was started on oral calcium/vitamin D3 and alendronate (70-mg tablets once a week) for osteoporosis. He reported an exacerbation of muscle weakness and extreme fatigue on days when he took alendronate. He could not work on these days and has to be on leave. Alendronate was stopped, and he was started on intravenous ibandronate injections given every 3 months. He did not experience muscle weakness and fatigue with ibandronate therapy. Alendronate should be used with caution in patients with myasthenia gravis who have corticosteroid-induced osteoporosis.Item Retrospective analysis of nosocomial urinary tract infections with spinal cord injury patients in a rehabilitation setting(Bayçınar Tıbbi Yayıncılık, 2014-02) Yılmaz, Bilge; Yavuz, Ferdi; Adıgüzel, EmreObjective: To define the distribution and antibiotic susceptibility of nosocomial urinary tract infections (NAUTIs) in patients with spinal cord injury (SCI). Material and Methods: Records of the spinal cord injured patients were reviewed for NAUTIs between 2008 and 2010. Antibiotic resistance rates and factors that might affect urinary tract infection susceptibility were investigated retrospectively. Results: The data of 276 patients were included, of whom 159 were acute SCI patients and 117 were chronic SCI patients; 166 (61%) infections were asymptomatic bacteriuria (ASB), and 110 (39%) infections were symptomatic urinary tract infections (SUTIs). In patients with acute SCI, E. coli was the most frequently isolated pathogen of SUTIs, followed by Pseudomonas. In patients with chronic SCI, E. coli was the most frequently isolated pathogen in SUTIs and ASBs. There was no statistically significant difference in the rates of NAUTI (ASB and SUTI) between acute and chronic SCI patients in terms of bladder drainage method. The susceptibility ratios for E. coli were very low in both acute and chronic SCI patients using Foley catheters. Although the susceptibility ratios for E. coli were not that low in SCI patients using clean intermittent catheterization, the resistance ratios were higher than 50% for most of the uropathogens. Conclusion: These results reveal a blunt truth that the treatment of NAUTIs will be a great challenge in near future.
