The last decade has been characterized by the emergence of CA-MRSA strains associated with the production of Panton-Valentine leukocidin. We report a case of necrotizing pneumonia and septic shock caused by CA-MRSA, in which early recognition of the syndrome and appropriate treatment with two toxin-suppressing antibiotics improved the patient's outcome.

We describe the epidemiology, clinical features, radiological findings, therapy and course for 15 patients hospitalized at the Infectious Diseases UOC of Gravina Hospital Caltagirone for a serious respiratory condition with verified infection A (H1N1) from 9 November to 22 December 2009. We retrospectively reviewed medical records, laboratory and instrumental tests performed on hospitalized patients. All patients had significant respiratory impairment: nine had co-morbidities and risk factors such as obesity, pregnancy, immunosuppressant conditions and muscular dystrophy. ⋯ All patients received antiviral and symptomatic therapy for 5-21 days. A(H1N1) virus infection led to a mild to moderate flu syndrome, which was often cured by symptomatic treatment; some patients required hospitalization for viral pneumonia, mixed pneumonia or ARDS. In previous flu epidemics there was no development into ARDS (40% in our series).

A study was carried out to assess treatment success and the overall costs of patients with ventilator-associated pneumonia (VAP). In a prospective case control study, data were collected from 25 intensive care unit (ICU) beds. A total of 162 ICU patients who required mechanical ventilation were assessed. ⋯ The additional cost for VAP was found to be USD 5980 per patient. These data suggest that morbidity, mortality, ICU length of stay and costs increase with VAP. The additional costs for VAP are especially based on the use of novel and expensive antibiotics, other drugs, and medical material.

Case Reports
[Icteric hepatitis in a patient with non-Hodgkin's lymphoma treated by rituximab-based chemotherapy].
We report the case of a patient with non-Hodgkin's lymphoma who, during chemotherapy according to the r-CHOP schedule (rituximab-cyclophosphamide-doxorubicin-vincristine and prednisone), showed a hepatic flare with jaundice. Given the patient's state of asymptomatic carrier of HBsAg, we began a treatment of telbivudine (600 mg/die), resulting in a regression of hepatitis flare and negativization of HBV viraemia.

Multicenter Study
Tigecycline in the treatment of ventilator-associated pneumonia: experience from the Latin American Tigecycline Use Registry.
The aim of this study was to evaluate the clinical success rate of the patients with ventilator-associated pneumonia (VAP) treated with tigecycline. ⋯ As initial evidence, our results suggest that tigecycline may be an acceptable alternative for therapy in patients with VAP. Nevertheless, only controlled clinical trials will provide the evidence to support approval for new indications.
