The use of qualitative methods in the study of parents' experiences of care on a children's surgical ward

User satisfaction with the care of hospitalized children is examined in this paper It is argued that parents are proxy consumers but that their status is conditional on the way in which they exercize choices Parents' involvement in the care of their children means that the term 'user' is more appropriate than 'consumer' Methodological problems in the assessment of user satisfaction are discussed A study of the experiences of parents of 24 children discharged from a surgical ward of a children's hospital is described and the implications for the assessment of user satisfaction reviewed The study demonstrates that qualitative methods have value in the assessment of user satisfaction with care A particular strength of qualitative methods of inquiry is that limitations of users' choice in care can be assessed     

Judgements and processes in care decisions in acute medical and surgical wards

The decisions which health care professionals make are the basis of treatment and care given. In order to evaluate effective care it seems logical to suggest that an awareness of the decisions which health care professionals make and how they make them is needed. This study examines the processes nurses use when making decisions about the health care needs of acutely ill patients. In stage one, 104 qualified nurses were interviewed to identify how they decide health care needs. In stage two, a 'think aloud' technique was used with patient simulations to obtain verbal protocols from a further 55 qualified nurses to identify the information strategies they used when making these decisions. The results suggest that nurses base their health care decisions mainly on their assessment of qualitative patient states or conditions. Initial indications are that the processes used differ from those characterized in the diagnostic reasoning model, with the context in which decisions are made being an important influence together with nurses' experience. It is suggested that, in order to develop effective predictive models and clinical guidelines which aid decision making, more research into the nature of health care professionals' decision making is carried out.     

Glucose utilization by intracranial meningiomas as an index of tumor aggressivity and probability of recurrence: a PET study

Seventeen patients with intracranial meningiomas were studied with positron emission tomography and fluorine-18-2-fluorodeoxyglucose (PET-FDG) to assess the glucose utilization of these tumors. Four meningiomas followed for 3-5 years after PET-FDG and surgery showed no evidence of recurrence. These tumors had significantly lower glucose utilization rates (1.9 mg/dl/min +/- 1.0) than 11 recurrent or regrowing meningiomas (4.5 mg/dl/min +/- 1.96) (P less than .01). The glucose metabolic rates of meningiomas correlated with tumor growth, as estimated from changes in tumor size on repeated computed tomographic scans. Histopathologically, a syncytial (atypical) meningioma had the highest glucose utilization rate, followed by a papillary meningioma and an angioblastic meningioma. Individual transitional and syncytial (typical) meningiomas showed marked differences in glucose metabolism despite similar microscopic appearance. Glucose utilization rate appears to be at least as reliable as histologic classification and other proposed criteria for predicting the behavior and recurrence of intracranial meningiomas.     

5例肺动脉血栓内膜剥脱术后神经系统障碍的临床特点及原因

目的 总结5例肺动脉血栓内膜剥脱术治疗慢性肺动脉血栓栓寨症术后神经系统障碍的患者的临床表现特点,并尝试分析其原因.方法 回顾2002年至2010年,26例因慢性血栓栓塞性肺动脉高压症行肺动脉血栓内膜剥脱术的患者围手术期资料.总结术后生存患者中5例出现神经功能障碍并发症者的临床与影像学特点,分析其与无并发症患者的手术前、手术中的资料,寻找可能的影响因素.结果 26例中围手术期死亡4例,22例生存者心功能改善,生活质量明显提高.5例围手术期出现神经系统障碍表现者中,3例表现为嗜睡、谵妄、记忆力障碍,颅脑CT未见异常发现,治疗后症状1周内消失,2周内完全恢复;另2例患者除上述症状外,还表现为共济失调、步态不稳、舞蹈样动作,症状持续时间长,其中1例经高压氧治疗后1个月症状好转,颅脑CT未见异常发现,颅脑MRI显示双侧中脑,基底节区异常信号,治疗8周症状基本好转出院,6个月症状完全消失,复查颅脑MRI异常信号消失;1例颅脑CT未见异常发现,12周出院,恢复较差,生活部分自理.术后出现神经系统障碍患者Jamieson手术分型Ⅲ型、Ⅳ型比例较多(P=0.024),手术中停循环时间较长(P=0.034).结论 肺动脉血栓内膜剥脱术后早期神经系统障碍多表现为弥漫性脑皮层与对称性基底节区神经功能障碍,颅脑MRI相应区域异常信号,多数患者症状在2-8周内消失,6个月内颅腩MRI异常信号可以消失.出现神经系统功能障碍的患者多手术操作难度大,停循环时间较长,推测考虑与术中脑缺血缺氧有关.

Abstract：

Objective Investigate the clinical features of the neurological disorders in patients after pulmonary thromboendarterectomy (PTE) for chronic pulmonary thromboembolism , analyze the factorial. Methods A retrospective study was made of 26 patients who underwent PTE between 2002 and 2010 in Beijing Chao-Yang hospital. The symptom of neurological system disorders occurred in the survivors were been investigate. The preoperative conditions and the perioperative conditions of all survivors were investigated. Compared the differences between the groups with neurological system disorders and the groups without. Results There were 22 patients of 26 survived after the surgery. Cardiac function of the survivors improved, and the quality of life improved significantly. 5 cases of the 22 survivors had symptoms of neurological system disorders. 3 patients showed lethargy, delirium, memory disorders, brain CT found no abnormal, symptoms recovered within 2 weeks. The fourth patient showed ataxia, unsteady gait, dance-like movements symmetry, in addition to the above symptoms, brain CT no abnormal showed,brain MRI showed bilateral abnormal signal in the midbrain, basal ganglia, symptoms improved and discharged after 8 weeks, the symptoms completely disappeared 6 months, and the abnormal signals in brain in MRI disappeared. The fifth patient with similar symptoms to the fourth, brain CT no abnormal found, be discharged 10 weeks after the operation, recovery is poor, living part of themselves. The postoperative neurological disorders occurred in the patients of Jamieson surgery type Ⅲ type, Ⅳ type of larger proportion, (P = 0.024), longer circulatory arrest surgery (P = 0.034). Conclusion The neurological disorders postoperative PTE often showed diffuse symmetric cerebral cortex and basal ganglia nerve dysfunction, brain MRI showed abnormal signal corresponding region, the majority of symptoms disappeared in 2 - 8 weeks, abnormal signal in brain MRI could disappeared after 6 months. Neurological dysfunction occurs in patients with more difficult surgical procedure, longer circulatory arrest, suggesting that with the surgery cerebral ischemia and hypoxia related.

Chronic arsenic poisoning from burning high-arsenic-containing coal in Guizhou, China

Arsenic is an environmental hazard and the reduction of drinking water arsenic levels is under consideration. People are exposed to arsenic not only through drinking water but also through arsenic-contaminated air and food. Here we report the health effects of arsenic exposure from burning high arsenic-containing coal in Guizhou, China. Coal in this region has undergone mineralization and thus produces high concentrations of arsenic. Coal is burned inside the home in open pits for daily cooking and crop drying, producing a high concentration of arsenic in indoor air. Arsenic in the air coats and permeates food being dried producing high concentrations in food; however, arsenic concentrations in the drinking water are in the normal range. The estimated sources of total arsenic exposure in this area are from arsenic-contaminated food (50-80%), air (10-20%), water (1-5%), and direct contact in coal-mining workers (1%). At least 3,000 patients with arsenic poisoning were found in the Southwest Prefecture of Guizhou, and approximately 200,000 people are at risk for such overexposures. Skin lesions are common, including keratosis of the hands and feet, pigmentation on the trunk, skin ulceration, and skin cancers. Toxicities to internal organs, including lung dysfunction, neuropathy, and nephrotoxicity, are clinically evident. The prevalence of hepatomegaly was 20%, and cirrhosis, ascites, and liver cancer are the most serious outcomes of arsenic poisoning. The Chinese government and international organizations are attempting to improve the house conditions and the coal source, and thereby protect human health in this area.
