STUDY OBJECTIVES To examine the incidence and response to treatment of adrenal insufficiency (AI) in high-risk postoperative patients. DESIGN Prospective observational case series. SETTING Large urban tertiary-care surgical ICU (SICU). PARTICIPANTS Adults > 55 years of age who required vasopressor therapy after adequate volume resuscitation in the(More)
Distant metastasis from colorectal carcinoma most often occurs in the liver and lungs. Metastasis to bones, adrenals, lymph nodes, brain, and skin has also been reported. Metastatic colorectal carcinoma to the testes is very uncommon. Even more uncommon is testicular metastasis from rectal carcinoma. Researchers throughout the last few decades have not(More)
From 1980 to 1986, during the Lebanon war, five patients with missile embolization were seen at the American University of Beirut Medical Center. Three had entry in the heart or thoracic aorta with peripheral embolization, and two had entry in the internal carotid artery and inferior vena cava with embolization to the middle cerebral artery and heart,(More)
Recent years have seen significant interest in designing networks that are self-healing in the sense that they can automatically recover from adversarial attack. Previous work shows that it is possible for a network to automatically recover , even when an adversary repeatedly deletes nodes in the network. However, there have not yet been any algorithms that(More)
Splenic metastases are unusual, arising in less than 1% of all metastases. Isolated solitary splenic metastasis from colorectal carcinoma is considered exceptional. This rarity has been explained by several hypotheses relating to the anatomical, histological, and immunological features of the spleen. We review the reported cases of isolated solitary splenic(More)
In the problem of reliable multiparty computation (RC), there are n parties, each with an individual input, and the parties want to jointly compute a function f over n inputs. The problem is complicated by the fact that an omniscient adversary controls a hidden fraction of the parties. We describe a self-healing algorithm for this problem. In particular,(More)
Berberine is a quaternary alkaloid derived from the plant Berberis aristata having antibacterial, antiamoebic, antifungal, antihelminthic, leishmanicidal and tuberculostatic properties. The effect of berberine sulphate salt on the growth of Trichomonas vaginalis in vitro was compared to the efficacy of metronidazole as a reference drug. Results showed that(More)
Model-based predictions are critically dependent on assumptions and hypotheses that are not based on first principles and that cannot necessarily be justified based on known prevalent physics. Constitutive models, for instance, fall under this category. While these predictive tools are typically calibrated using observational data, little is usually done(More)
