How do you assess the likelihood of antibiotic resistance in patients presenting with suspected pneumococcal infection? Vanderkooi and associates addressed this in a study of 3339 patients with invasive pneumococcal disease. They found that antibiotic use in the 3 months before the onset of infection was the most important risk factor for antibiotic resistance. The single most important risk factor for resistance to a particular antibiotic was previous use of antibiotics from the same class.
Vitamin E has been evaluated for the treatment and prevention of several different chronic diseases in numerous clinical trials over the past 2 decades. However, only a limited number of studies have investigated the potential therapeutic or prophylactic effect of vitamin E on allergic rhinitis and respiratory infections. In contrast to trials on cardiovascular disease, which have failed to demonstrate a benefit from vitamin E supplementation,1,2 there is mounting evidence that this essential vitamin may be useful for prevention of the common cold and treatment of allergic rhinitis.
Abstract: Tuberculous meningitis has several different clinical presentations, including an acute meningitic syndrome simulating pyogenic meningitis, status epilepticus, stroke syndrome, and movement disorders. Cranial nerve palsies and seizures occur in about one third of patients, and vision loss is reported by almost 50%. The cerebrospinal fluid (CSF) typically shows moderately elevated levels of lymphocytes and protein and low levels of glucose. The demonstration of acid-fast bacilli in the CSF smear or Mycobacterium tuberculosis in culture confirms the diagnosis. CNS tuberculosis may also manifest as intracranial tuberculomas. The characteristic CT and MRI finding is a nodular enhancing lesion with a central hypointensity. Antituberculosis treatment should be initiated promptly when either tuberculous meningitis or tuberculoma is suspected. (J Respir Dis. 2005;26(9):392-400)
