The surviving sepsis guidelines recommend early aggressive fluid resuscitation within 6 h of sepsis onset. Although rapid fluid administration may offer benefit, studies on the timing of resuscitation are lacking. We hypothesized that there is an association between quicker, adequate fluid resuscitation and patient outcome from sepsis onset time. ⋯ Earlier fluid resuscitation (within the first 3 h) is associated with a greater number of survivors with severe sepsis and septic shock.

Definitive diagnosis of pleural disease (particularly malignancy) depends upon histologic proof obtained via pleural biopsy or positive pleural fluid cytology. Image-guided sampling is now standard practice. Local anesthetic thoracoscopy has a high diagnostic yield for malignant and nonmalignant disease, but is not always possible in frail patients, if pleural fluid is heavily loculated, or where the lung is adherent to the chest wall. Such cases can be converted during the same procedure as attempted thoracoscopy to cutting-needle biopsy. This study aimed to determine the diagnostic yield of a physician-led service in both planned biopsies and cases of failed thoracoscopy. ⋯ Within this population, physician-based, ultrasound-guided, cutting-needle pleural biopsy obtained pleural tissue successfully in a high proportion of cases, including those of failed thoracoscopy.

Clinical Trial
Increased Day-To-Day Variability of Forced Oscillatory Resistance in Poorly Controlled or Persistent Paediatric Asthma.
Pediatric asthma lacks sensitive objective measures for asthma monitoring. The forced oscillation technique (FOT) offers strong feasibility across the pediatric age range, but relationships between FOT parameter day-to-day variability and pediatric asthma severity and control are unknown. ⋯ Increased day-to-day FOT variability exists in school-aged children with asthma. Day-to-day Rrs variability was associated with asthma severity and asthma control. FOT may be a useful objective monitoring tool in pediatric asthma and warrants further study.

Case Reports
Survival following investigational treatment of amanita mushroom poisoning: thistle or shamrock?
We report the first case, to our knowledge, of amatoxin hepatotoxicity in Iowa and explore the ethical and decisional challenges of offering an investigational treatment of a rare disease. Acute liver failure due to ingestion of amatoxin-containing mushrooms is a relatively rare entity. ⋯ We explore the pitfalls in medical decision-making experienced by both the patient and the physician in the face of ambiguity. The patient did well following silibinin infusion, but we are left uncertain as to whether the patient truly responded to treatment or was simply destined to recover.

Streptococcus anginosus has long been recognized to cause invasive pyogenic infections. This holds true for thoracic infections where S. anginosus has a propensity for abscess and empyema formation. Early diagnosis is important given the significant morbidity and mortality associated with thoracic S. anginosus infections. ⋯ We present three cases of thoracic S. anginosus that demonstrated radiographic extension across tissue planes, including the interlobar fissure, diaphragm, and chest wall. Few infectious etiologies are known to cross tissue planes. Accordingly, we propose S. anginosus be considered among the differential diagnosis of potential infectious etiologies causing radiographic extension across tissue planes.
