Correspondence How artificial is the antibiotic resistance definition?
Streptococcus pneumoniae is naturally susceptible to β-lactams since no β-lactamases have been described in this bacterium.1 Penicillin and cefotaxime, the preferred antibiotics for treating pneumococcal infections, act in the same way on S pneumoniae by inhibiting the peptidoglycan assembly.1 Thus, biologically, there should be no pneumococcus resi stant to cefotaxime and resistant to penicillin. However, defining the minimum inhibitory concentrations (MICs) that indicate whether a bacterium is susceptible, intermediate, or resistant to antibiotics is a complex issue that depends on the microorganism, patient, and antibiotic used.
CONCLUSION: Essential and dystonic vocal tremors responded differently to treatment. Dystonic vocal tremors responded significantly to treatment with botulinum toxin but not oral propranolol. Essential vocal tremors did not respond significantly to either treatment, perhaps due to the small number of patients, which is a limitation of this research.
CONCLUSION: Patients arrived very sick and displayed poor survival after deceased donor transplantation.
CONCLUSION: Except for the STOP-BANG questionnaire, subjective evaluation of sleepiness, sleep quality, perception of onset, and total sleep time are not important parameters for the diagnosis of obstructive sleep apnea, which reinforces the need for an active search for better management of these patients.
