A survey was conducted in early 1985 among 366 new mothers at 3 hospitals in Pinar del Rio, Cuba, to assess their level of health information regarding the care of newborns. The 11 study variables included breastfeeding, weaning, bathing the newborn, care of clothing and equipment for the baby, well baby visits, vaccination, accidents and safety, parent-child relations, sex education, and the puerperium. The level of information on these topics was generally low and was adequate only for breastfeeding. The information deficit was not related to urban or rural residence, parity, or educational level. The lack of knowledge of new mothers was attributed to the lack of motivation of health personnel at all levels to provide health education, inadequate use of existing information channels, and a lack of emphasis on health education within the general educational system. 相似文献

The capacity of blood pressure cuffs to act as vehicles of hospital infection has been recognised. We describe the microbial
flora of in-use DINAMAP blood pressure cuffs used in the operating theatres and one recovery room in a teaching hospital.
Our results show significant microbial contamination of in-use blood pressure cuffs. 相似文献

Anatomically, the thigh is well covered by soft tissue in the form of the muscles surrounding the shaft. In the assessment of the severity of an injury, not only the obvious skin wound but also the mechnism of the trauma has to be considered. The extent and severity of the soft tissue damage cannot usually be fully established until later in the course of treatment, when necrosis of the skin, the subcutaneous fat and the musculature and also compartment syndrome or a secondary disturbance of perfusion may become obvious. Therefore, when extensive soft tissue injuries are present, following the primary débridement, a repeat wound débridement after 24–48 hours is generally indicated. Only after consolidation of the wounds and the successful treatment of any infection is definitive soft tissue reconstruction performed. The main danger in the treatment of soft tissue injuries of the thigh is underestimation of their total extent. 相似文献

We describe the clinical and pathological findings of the hemolytic uremic syndrome (HUS) in two children with human immunodeficiency
virus (HIV) infection. Both patients presented with microangiopathic hemolytic anemia, thrombocytopenia, and subsequently
developed renal failure. The diagnosis of HUS was confirmed by renal histopathology in both patients. None of these children
presented with bloody diarrhea, evidence of circulating antibody response to Escherichia coli O157 lipopolysaccharide, or other known risk factors for HUS, except for the presence of HIV infection. Each patient was
treated with intravenous plasma infusion and renal replacement therapy. Their clinical course was characterized by non-oliguria
and lack of significant hypertension throughout the acute phase of the disease. Despite these favorable clinical parameters,
both patients developed end-stage renal failure. The etiology of this atypical HUS characterized by poor renal survival remains
unknown and the role of HIV infection in its pathogenesis, although possible, is unclear.

Background: Docetaxel, a semi-synthetic taxane may cause a usuallymild sensory neuropathy. We describe the clinical characteristics of fivepatients who developed a more severe neuropathy following treatment withdocetaxel.Patients and methods: All patients were treated in phase II studieswith 100 mg/m2 docetaxel in three weekly cycles, withoutsteroid administration.Results: The clinical picture in these patients was dominated by asensory neuropathy, but in one case severe weakness was present. Anotherpatient developed Lhermitte's sign. Signs and symptoms are usually reversibleafter discontinuation of docetaxel administration, but in three patientssymptoms worsened for some time after the end of treatment before improvementoccurred.Conclusion: Severe docetaxel neuropathy may especially occurfollowing treatment with cumulative dosage over 600 mg/m2; inpatients treated with this dosage a moderate or severe neuropathy may not berare. 相似文献
