A 76-year-old patient developed necrosis of the index finger after placement of a radial artery catheter. This article discusses the risks associated with invasive blood pressure monitoring and treatment options in cases of critical ischemia. The authors conclude that there is no consensus concerning optimal treatment and that a discussion on options for preoperative risk assessment and quickest possible recognition of such complications is worthwhile. Despite the risk of ischemia invasive blood pressure monitoring is an indispensable procedure. 相似文献

In 1998, two cases of severe dental fluorosis in schoolchildren occurred in the Muenster region. These cases took place in one household, where fluoridated toothpaste, fluoridated salt, and fluoride tablets were consumed. Furthermore, the family used drinking water from its private well only. Analyses of the well water ordered by local health officials revealed very high amounts of fluoride, boron, and other electrolytes. This unusual combination of high amounts of fluoride and boron could also be found in the water of a great number of other private wells that are the only source for drinking water in this rural region of the Muensterland. Anthropogenic sources could be excluded. Because of this, the results of the water samples were collated to the specific geological situation in this area. In the Muenster region there are marl layers of the chalk era covered with quarternary sediments. The quarternary sediments are up to 10 to 20 metres thick and they usually conduct the groundwater. The marl contains high concentrations of fluoride and boron. In some places the groundwater has contact with these layers. To check the amount of fluoride and boron in the groundwater, indicator values were sought, which can give a hint of high contents of these trace elements. In this study the conductivity and acidity were identified as possible indicators of a high amount of fluoride and boron in the drinking water in this specific region. To work economically and efficiently, the drinking water should be checked for fluoride and boron on a regular basis only when these values are extraordinarily high. In the case of high concentrations, especially of fluoride, in the drinking water the persons concerned should be informed about their potential health risk, giving them the opportunity to optimise the total daily intake of fluoride. 相似文献

OBJECTIVE: This study was undertaken to measure neurokinin B (NKB) levels in pregnant women with and without preeclampsia (PE) in the third trimester. The study focused on the Black (sub-Saharan ancestry) and 'mixed ancestry' (synonymous with 'colored' and denotes an established race group of Khoisan, European, Malay, Malagascan, African, and South Indian ancestry) populations, constituting the majority of inhabitants of the Western Cape Province of South Africa. METHODS: Questionnaires were used to obtain clinical data from pregnant 'mixed ancestry' and Black women. Third trimester plasma NKB levels were determined by enzyme-linked immunosorbent assay technique (EIA) in 72 pregnant women with PE and in 94 healthy women. The EIA results were then correlated with clinical data. RESULTS: The mean NKB concentration in the PE groups (23.5 ng/L for 'mixed ancestry' and 15.0 ng/L for Black women) was significantly higher than in the control groups (3.8 ng/L and 4.4 ng/L, respectively; p < or = 0.001). No significant differences in maternal clinical data were found between the diseased groups. CONCLUSIONS: Using the EIA technique, this study confirms previous reports of elevated NKB levels in the plasma of PE women in the third trimester. Whether increased NKB levels are causative or merely associated with PE remains unknown, as do the causative molecular mechanisms. Future longitudinal studies are certainly needed to further elucidate the predictive value of NKB in PE. 相似文献

The dedicated target region should be systematically examined before performing an ultrasound-guided nerve block so that the anatomy can be assessed and anatomic variants or pathologic findings are not missed. In the case described an ultrasound-guided interscalene plexus block was performed in a 73-year-old man. During this examination a cystic structure was detected within the thyroid gland. The further diagnostic procedure showed a metastasis of a renal cell carcinoma which had been treated by resection 10 years before. 相似文献
