Results of three therapeutic modalities used for the treatment of a homogeneous series of patients with a Pouteau Colles fracture are analyzed. Orthopedic treatment provided deceiving results. Pinning was, on the contrary, very effective, intrafocal pinning with immediate mobilization of the wrist appearing perfectly effective. Few complications were reported in contrast to plastered immobilizations. Good results were obtained in 80% of cases and functional recovery was rapid, indicating that this method represents undoubted progress when compared with conventional therapies. 相似文献

Caustic injuries to the esophagus in children 总被引:2,自引:0,他引:2
F C Rothstein 《Pediatric clinics of North America》1986,33(3):665-674
The ingestion of caustic chemical agents, usually accidentally by children, produces a wide range of injuries from minor mouth burns to necrosis of the esophagus and stomach. The type of agent, amount, concentration, and duration of exposure are the determining factors. The treatment for the average burn is fairly well standardized, but the serious injuries require prompt recognition of complications and appropriate therapy to prevent more serious complications. 相似文献

We cared for a patient with methicillin-resistant Staphylococcus aureus bacteremia who experienced clinical failure with daptomycin. The failure was accompanied by progressive elevation of the daptomycin minimum inhibitory concentration during treatment. DNA fingerprinting confirmed that the minimum inhibitory concentration elevation occurred within the same strain of methicillin-resistant Staphylococcus aureus. This observation provides important new information to clinicians who adopt this promising drug for treatment of serious infections caused by methicillin-resistant Staphylococcus aureus. 相似文献

Die therapieinduzierte Neutropenie kann mit den Kolonie stimulierenden Faktoren (CSF) der Granulopoese (G-CSF und GM-CSF)
vermieden,abgemildert oder in ihrer Zeitdauer verkürzt werden. Die CSF erm?glichen die Mobilisation h?matopoetischer Stammzellen
in das Blut und deren Sammlung für die Transplantation nach Hochdosistherapie.Diese Faktoren sind daher essenziell in der
Supportivtherapie maligner Erkranklungen. Der Arbeitskreis Supportivma?nahmen in der Onkologie (ASO) der Deutschen Krebsgesellschaft
hat Richtlinien zur Therapie mit den Kolonie stimulierenden Faktoren entwickelt, die unterschiedlichen klinischen Situationen
angepasst sind. Der vollst?ndige Text wurde 12/2001 in “Der Onkologe” publiziert [23], er ist auch auf der Homepage des ASO
unter http://www.onkosupport.de zu finden [24].

The endotoxin receptor soluble CD14 (sCD14) has been implicated in the 'hygiene hypothesis' suggesting reduced allergic sensitization with bacterial stimulation. However, the relationship between early life sCD14 and allergic diseases is conflicting. We aimed to investigate whether possible risk factors for allergic diseases were associated with sCD14 levels at 2 yr of age. In the nested case-control study of the birth cohort studies 'Environment and Childhood Asthma study in Oslo' 411 children selected with recurrent bronchial obstruction (rBO) (n=241) and no bronchial obstruction (n=170) by 2 yr were investigated with skin prick test and structured parental interview at age 2 yr. Exposure to tobacco smoke, pets and infections was recorded semi-annually by questionnaires (0-2 yr). The sCD14 was analysed from frozen, stored serum by ELISA technique. Regression analyses were performed in all subjects with complete data (n=406, 180 girls), and in girls and in boys separately. Mean sCD14 (ng/ml) was significantly higher among girls 2035 (1973-2096) vs. 1947 (1890-2004) (boys). The sCD14 was significantly reduced among girls exposed to antenatal maternal smoking and with parental asthma, after adjusting for age, parental rhino-conjunctivitis, pet keeping and childhood infections. Recurrent otitis media (OM) increased and common colds significantly decreased sCD14 levels in girls. Boys with atopic dermatitis and rBO had reduced sCD14. Pet exposure was not significantly associated with sCD14. We report novel gender-related effects of sCD14 in early life and suggest that gender, tobacco smoke exposure, age and middle ear disease in particular should be accounted for when assessing the role of sCD14 in childhood allergic diseases. 相似文献
