Current evidence leads to uncertainty whether mild CDAD needs to be treated. The studies provide little evidence for antibiotic treatment of severe CDAD as many studies excluded these patients. Considering the two goals of therapy: improvement of the patient's clinical condition and prevention of spread of C. difficile infection to other patients, one should choose the antibiotic that brings both symptomatic cure and bacteriologic cure. A recommendation to achieve these goals cannot be made because of the small numbers of patients in the included studies and the high risk of bias in these studies, especially related to dropouts. Most of the active comparator studies found no statistically significant difference in efficacy between vancomycin and other antibiotics including metronidazole, fusidic acid, nitazoxanide or rifaximin. Teicoplanin may be an attractive choice but for its limited availability (Teicoplanin is not available in the USA) and great cost relative to the other options. More research of antibiotic treatment and other treatment modalities of CDAD is required.

Third-line antiepileptic drug therapies with sedating or anesthetic effects predicted poor outcome and death in status epilepticus. Hypotension requiring vasopressor therapy and duration of mechanical ventilation induced by these agents may be contributing factors, especially when pentobarbital is used. These findings may inform decision making on drug therapy in status epilepticus and help develop safer and more effective treatment strategies to improve outcome.

In a prospective study, 31 patients with brown recluse spider bites were treated by either immediate surgical excision or with the leukocyte inhibitor, dapsone, followed by delayed surgical excision. Patients were matched for age, gender, and lesion size and were excluded if the typical history and physical findings were not present. In patients treated with immediate surgical excision (N = 14), delayed wound healing (N = 5) and objectional scarring (N = 7) were common complications. However, pretreatment with dapsone reduced the incidence of wound complications (N = 1) and objectional scarring (N = 1) (p < 0.05), while reducing the need for surgical excision (N = 1). There were no severe drug reactions due to dapsone, although one patient had persistent G.I. upset. Pretreatment with dapsone not only reduced surgical complications but also improved the outcome of patients bitten by the brown recluse spider.
