A 31-year-old Nepali man was admitted to the intensive care unit with a 3-day history of fever associated with four-limb weakness, followed by difficulty in swallowing. The patient came from Nepal 20 days before admission. On examination the patient was conscious and appeared ill, with a temperature of 38.0 degrees C. His four limbs were weak (grades 2-3) and he was areflexic with mild facial weakness and absent gag reflex. Brain CT and MRI were normal. Cerebrospinal fluid analysis showed high protein. A neurophysiologic study showed data consistent with motor axonal polyradiculopathy. The patient was diagnosed with Guillain-Barré syndrome (GBS), and intravenous immunoglobulin (0.4 g/kg day for 5 days) was administered. On the third hospitalization day, the patient developed respiratory failure for which he was intubated and mechanically ventilated. On the same day, blood samples grew Salmonella paratyphi A (S. paratyphi A), which was sensitive to ceftriaxone. The patient was then diagnosed with GBS associated with S. paratyphi A, and treated with ceftriaxon (2 g administered intravenously, daily for 10 days). On the eleventh hospitalization day the patient was weaned from ventilator and extubated successfully. Subsequently, the patient improved, his fever subsided, and he regained muscle power satisfactorily. 相似文献

Objective To explore adrenal function in severe West Nile virus (WNV) infection.Design and setting Prospective interventional cohort study in a medical ICU of a teaching hospital.Patients Ten consecutive patients (seven men, mean age 64 ± 12 years, mean SAPS II 26 ± 6) with definite diagnosis of WNV related meningoencephalitis and variable proportion of organ/system failure. All patients had fever (mean body temperature 39 ± 1°C) and altered mental status (mean Glasgow Coma Score 11 ± 2). Mean SOFA score was 9 ± 2; eight patients had systemic inflammatory response syndrome, five septic shock, and six acute respiratory failure (usually from central origin) requiring mechanical ventilation.Interventions A short corticotropin test was performed in each patient to assess the adrenal function.Measurements and results Cortisol response was defined as the difference between baseline and corticotropin-stimulated peak. Absolute adrenal insufficiency was defined by a baseline cortisol level below 15 μg/dl (415 nmol/l). Relative insufficiency was defined by a cortisol response of 9 μg/dl (250 nmol/l) or less. Relative adrenal insufficiency, defined by a corticotropin response below 9 μg/dl, was observed in seven while the remaining three had normal cortisol response; six out of these seven died in the ICU. All patients with normal adrenal function survived.Conclusion Adrenal insufficiency is frequent in severe WNV infection and carries a poor outcome. In the absence of specific effective treatment, our data provide a rational to investigate a supplemental corticosteroid treatment in a controlled trial. 相似文献

We identified a novel inter-genotype recombinant norovirus strain, Dhaka85/2011/BGD, collected from a stool specimen of a nine-month-old infant who was hospitalized with diarrhea. Molecular investigation and phylogenetic analysis classified its RNA polymerase gene as GII.4-like, which commonly circulates in humans. The capsid gene was classified as GII.21-like, most likely originated from water. The discovery of this novel strain is an illustration of the enormous diversity among the norovirus strains, especially in developing countries and has important implications for future vaccine strategies. 相似文献

Mexican Americans are the largest subgroup of Hispanics, the largest minority population in the United States. Stroke is the leading cause of disability and third leading cause of death. The authors compared stroke incidence among Mexican Americans and non-Hispanic Whites in a population-based study. Stroke cases were ascertained in Nueces County, Texas, utilizing concomitant active and passive surveillance. Cases were validated on the basis of source documentation by board-certified neurologists masked to subjects' ethnicity. From January 2000 to December 2002, 2,350 cerebrovascular events occurred. Of the completed strokes, 53% were in Mexican Americans. The crude cumulative incidence was 168/10,000 in Mexican Americans and 136/10,000 in non-Hispanic Whites. Mexican Americans had a higher cumulative incidence for ischemic stroke (ages 45-59 years: risk ratio = 2.04, 95% confidence interval: 1.55, 2.69; ages 60-74 years: risk ratio = 1.58, 95% confidence interval: 1.31, 1.91; ages >or=75 years: risk ratio = 1.12, 95% confidence interval: 0.94, 1.32). Intracerebral hemorrhage was more common in Mexican Americans (age-adjusted risk ratio = 1.63, 95% confidence interval: 1.24, 2.16). The subarachnoid hemorrhage age-adjusted risk ratio was 1.57 (95% confidence interval: 0.86, 2.89). Mexican Americans experience a substantially greater ischemic stroke and intracerebral hemorrhage incidence compared with non-Hispanic Whites. As the Mexican-American population grows and ages, measures to target this population for stroke prevention are critical. 相似文献

We present an infant with true trisomy 22. Mosaicism is ruled out by the finding of a 47,XX, +22 karyotype in all cells analysed originating from two embryonic germ layers. The physical findings are consistent with the previously noted features including developmental delay, ear abnormalities, micrognathia, clefting, and congenital heart disease. The patient is the first described with macrocephaly and hydrocephalus and the second with holoprosencephaly. 相似文献
