摘要:

Congenital absence of one pulmonary artery is rare and may remain unrecognized until adulthood. Malignant neoplasm in the affected lung has only been noted twice in the English literature, and neither report provided any follow-up data. We report the occurrence of adenocarcinoma in the lung of a young woman with congenital absence of the ipsilateral pulmonary artery. Surgical resection of the malignant lesion was performed, and no recurrence has been detected for 10 years. A high index of suspicion is required to recognize congenital abnormalities of the pulmonary vasculature, especially in adults. Therefore, we reviewed the literature concerning the various congenital abnormalities of the pulmonary arteries and veins. Because of the infrequent nature of these congenital lesions, most reports provide only limited clinical data. No longitudinal natural history studies are available. As such, therapeutic recommendations are based on small series and case reports for most of these conditions.

摘要:

SYNOPSIS: Early-stage lung cancer is best treated by resection, but frequently patients with lung cancer and severe emphysema are denied this option because of poor preoperative pulmonary function. Lung volume reduction is now emerging as a means of resecting up to 30% of destroyed parenchyma, resulting in improvement in pulmonary function. Hence, this leads to the concept of combination therapy-resect the cancer and the decayed emphysematous tissue, leaving the patient cancer-free and with improved pulmonary status. The authors used this aggressive approach in a series of five patients with severe emphysema. Although their study sample was small, it is important to note that all did well postoperatively, and subjective and objective improvement was seen in serial postoperative pulmonary function tests (PFTs). The authors propose the combination of lung volume reduction surgery (LVRS) and lobectomy as a new option in the treatment of this difficult problem.SOURCE: DeMeester SR et al.

摘要:

SYNOPSIS: The use of a nasal cannula/pressure transducer device to measure airflow during polysomnography (PSG) is more sensitive than the commonly used thermistor at detecting flow limitation. This device will aid in the diagnosis of upper airway resistance syndrome.SOURCE: Hosselet JJ et al. Detection of flow limitation with a nasal cannula/pressure transducer system.

摘要:

SYNOPSIS: A multicenter, prospective, nonrandomized study was performed to evaluate a new continuous cardiac output monitoring system and compare it with the currently used method, intermittent injection thermodilution. Forty-seven critically ill adult patients had cardiac output monitored over a 72-hour period simultaneously with both methods. In this study, the continuous cardiac monitoring system turned out to be a reliable method that was not adversely affected by abnormal patient temperature (<37°C or >38°C), high (>7.5 L/min) or low (<44.5 L/min) cardiac output, or duration (72 hours) of the study.SOURCE: Mihm FG et al.

摘要:

SYNOPSIS: Filgrastim (granulocyte colony-stimulating factor [G-CSF]) was given as daily injections of 75 μg or 300 μg versus placebo in a randomized fashion to 61 patients with acute severe traumatic brain injury or intracranial hemorrhage, requiring mechanical ventilation, for 10 days. There was a dose-dependent increase in absolute neutrophil count, and patients receiving G-CSF had a lower incidence of primary bacteremia but no difference in rates of nosocomial pneumonia or urinary tract infections. Similarly, there was no effect on length of stay in the intensive care unit (ICU) or mortality, and adverse effects were similar in placebo and treatment groups.SOURCE: Heard SO et al. Effect of prophylactic administration of recombinant human granulocyte colony-stimulating factor (filgrastim) on the frequency of nosocomial infections in patients with acute traumatic brain injury or cerebral hemorrhage.
