Patients with influenza A (H1N1) virus infection have been admitted to intensive care units (ICU) due to development of severe respiratory failure. We described the clinical and epidemiologic characteristics of the 19 patients admitted to ICU due to influenza A (H1N1) virus infection. Study design is a descriptive case series in a third level-20 bed respiratory ICU at training hospital in Istanbul/Turkey. ⋯ ICU mortality rate was 21.1%. Presenting patients with pneumonia and acute respiratory failure due to influenza A (H1N1) virus infection were treated predominantly and successfully with non invasive mechanical ventilation. Clinicians should be aware of pulmonary complications of influenza A (H1N1) virus infection and that patients can be treated with non invasive mechanical ventilation paying attention to protective measures for health care providers.

In intensive care units, venous thromboembolism (VTE) is a life threatening, clinically important issue. The diagnosis of VTE is significantly complicated, even in patients except intensive care units and there is no consensus between clinicians about its treatment. The factors such as heterogeneity of intensive care units patients, the association of thrombosis and bleeding risks in the majority of patients, the non-specific signs and symptoms of VTE, the feasibility limitations of diagnostic methods are caused difficulties in the diagnosis and treatment of VTE. In this review, it has been aimed to remind VTE issue in the intensive care units, by review the investigations about the diagnosis, treatment and thromboprophylaxis of VTE.

[The role of physiologic dead space measurement in predicting extubation success].
Dead space ventilation (Vd/Vt) is a valuable parameter which indicates the ventilated but not perfused lung areas. The normal range is between 30-50% in mechanically ventilated patients. Increased levels could be observed in many pulmonary diseases such as pulmonary embolism, acute respiratory distress syndrome and chronic obstructive pulmonary disease. ⋯ When the two groups were compared, Vd/Vt value, measured at the first 24 hours of hospitalization, was found to be higher in group 2 (0.66 vs. 0.54, p< 0.05). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of baseline Vd/Vt ≥ 0.60 for predicting extubation failure according to ROC curve were 70%, 72%, 58%, 81% and 71%, respectively. In conclusion, results of this study suggest that, higher Vd/Vt values measured on the first day of hospitalization may be an early predictor of extubation failure.

Mortality prediction in community-acquired pneumonia requiring mechanical ventilation; values of pneumonia and intensive care unit severity scores.
Severe community-acquired pneumonia (CAP) is an important cause of intensive care unit (ICU) admissions. Many different pneumonia scoring systems have been developed in order to assess the severity of pneumonia and to decide the ICU follow-up and treatment. But still debate is going on about their performances and also they have not been tested yet if they can predict ICU mortality in severe CAP patients requiring mechanical ventilation. ⋯ Although the CURB-65, PSI, revised ATS criteria were not found valuable to predict mortality, the increased APACHE II score was found to be related with increased mortality rate (for APACHE II > 20 odds ratio: 3, 95% CI: 1.2-7, p= 0.024). These results suggest that instead of the pneumonia scoring systems the APACHE II score can best predict the ICU mortality. So, more attention should be paid for severe CAP patients with APACHE II score > 20.

Case ReportsDysphonia and chest pain as presenting symptoms of pneumomediastinum.
Spontaneous pneumomediastinum (SPM) is a rare but generally benign condition characterized by the presence of free air in the mediastinal space that is unrelated to trauma or medical procedure. We describe a case of a 25-year-old woman who presented to the emergency room with a chief complaint of dysphonia, and chest pain. ⋯ Supportive treatment led to an uneventful recovery. We discuss the differential diagnosis of the coexisting chest pain and dysphonia in the diagnosis of SPM.
