Abstract
BACKGROUND Rehabilitation is increasingly being introduced in dementia care but studies highlight extensive heterogeneity in practices, conceptual confusion and divergent perceptions of its relevance across care organizations and national contexts. As this have implications for development of dementia care as well as for people with dementia's access to care it is important to study the organizational narratives and practices in rehabilitation-oriented dementia care organizations. METHODS The study build on qualitative interviews (individual and group interviews) with health professionals (N = 26) engaged with dementia care and rehabilitation in two Danish municipalities. The interviews were conducted in 2018-2019. The empirical data was analyzed using abductive analysis and theory-based narrative analysis, using Loseke's conceptualizations of and approach to analyzing formula stories. FINDINGS Four dominant organizational narratives were constructed from the data. Each narrative produced a specific organizational narrative of client identity: the active participant in individualized rehabilitation, the inactive individual benefitting from enhanced social environments, the disengaging self and the vulnerable self. CONCLUSION Introducing rehabilitation in dementia care may amplify the organizational polyphonic and provide a plurality of organizational identities each expressing different perceptions of personhood and agency for people with dementia. The organizational narratives were negotiated within a specific structural context where national regulation and dominant discourses on economic challenges and ageing gave precedence to some narratives more than others. In Danish elder care, the first narrative is the most influential but risks excluding people with dementia. Instead, rehabilitation in dementia care is positioned within a social and relational perspective, which may silence important discussion of agency and resistance.

Abstract
Due to its goal-orientation, rehabilitation may be considered a future-oriented practice.
As rehabilitation is increasingly recognized as contributing to dementia care it is
important to explore how rehabilitation corresponds with the future orientation of older
people with dementia. The aim of this study was to explore the futurework of home-dwelling people with mild to
moderate dementia in the context of rehabilitation-focused municipal dementia care, that
is, their thinking and practices regarding their future and how these correspond with
institutionalized practices. The study was conducted as a case-study inspired by the methodology of Institutional
Ethnography (IE). The study setting was two Danish municipalities sampled as a
paradigmatic case. Eight older people living with early-stage dementia (mean age: 78
years, age range: 65–91) were strategically sampled and each interviewed recurringly
within a period of six through 15 months. In total, 29 interviews were completed. An
abductive analysis was subsequently conducted based on these interviews. Findings included three dimensions of futurework: Extending the present state into the
near future; avoiding being confronted with an anticipated future; and adjusting to
decline and preparing for future losses. Based on these findings, a notion of ‘ambivalent
futurework’ is suggested. The futurework of older people did not always correspond with
the institutional arrangements in a rehabilitation-focused dementia care. Findings show
that the institutional arrangements in dementia care may support as well as challenge the
futurework of the participants. Paying attention to the ambivalences of older people
living with dementia and recognizing the ambivalent futurework may be essential in
rehabilitation-focused dementia care.

Abstract
BACKGROUND Reablement services are intended to make a difference in the daily lives of older adults. Outcomes are often described in terms of independence, improving quality of life, improving ADL functioning, or reducing services. However, little is known if the older adults or next-of-kin experience these outcomes when talking about participating in reablement services. AIM This study aims to explore how older adults, next-of-kin, and professionals narrate the reablement recipients' possible outcomes as gains and changes in everyday life during and after the reablement period. MATERIALS AND METHODS This meta-synthesis included 13 studies. Data were analyzed with a meta-ethnographic approach, searching for overarching metaphors, in three stages. RESULTS The metaphor 'the jigsaw puzzle of activities for mastering daily life again' illustrates that re-assembling everyday life after reablement is not a straightforward process of gains and changes but includes several daily activities that must be organized and fit together. To obtain a deeper understanding of the participants' gains, and changes after reablement, we use the theoretical framework of 'doing, being, becoming, and belonging'. CONCLUSION The findings indicate the complexity of reablement services as well as the need for a holistic approach. SIGNIFICANCE Outcome measures should be meaningful for reablement recipients.

Abstract
As our societies age, we see more people with disabilities living well into old age. However, there are different societal, systemic and individual assumptions about needs, rights and obligations associated with frail older people and people with disabilities. The paper presents quantitative results from a Danish study investigating what challenges ageing of society pose for the individual as well as for the welfare state in regards to meeting the needs of those who either age into disability or age with disability. Using panel data from the Danish Level of Living Survey from 1997-2017, we investigate how ADL related needs for care have changed for the 52+ year olds and we project how needs will change in the near future. Finally, we show how different systemic approaches to need assessment for those under or above 65, but with otherwise identical and socio-economic backgrounds, result in a very different service utility.

Expression of vesicular monoamine transporters, synaptosomal-associated protein 25 and syntaxin1: a signature of human small cell lung carcinoma. Cancer Res 2001; 61:2138-44.

Abstract
Vesicular monoamine transporters (VMATs) are a prerequisite for the uptake of biogenic amines into intracellular storage organelles, whereas soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs; such as SNAP-25 and syntaxin1) are essential for exocytosis of biogenic amines by neurons and endocrine cells. In this study, we examined whether these proteins exist in high-grade malignant small cell lung carcinomas (SCLCs), large cell carcinomas, adenocarcinomas, and squamous cell carcinomas of the lung. We analyzed two established human SCLC cell lines, one adenocarcinoma cell line, paraffin-embedded tumors (SCLC, n = 25; large cell carcinoma, n = 10; adenocarcinoma, n = 10; squamous cell carcinoma, n = 10), and snap-frozen SCLC samples (n = 2). Using immunocytochemistry, Western blotting, Northern blotting, RT-PCR, and sequencing, we identified VMAT1, VMAT2, SNAP-25, and syntaxin1 in cultured SCLC cells. Immunohistochemistry carried out on paraffin sections revealed that all SCLC tumors express VMAT1, VMAT2, SNAP-25, and syntaxin1. The presence of SNAP-25 and syntaxin1 in SCLC was confirmed by RT-PCR performed with material extracted from paraffin sections. Western blot analysis and RT-PCR carried out with snap-frozen SCLC tumors revealed the presence of SNAREs and VMATs. Immunohistochemistry showed that non-SCLC tumors were negative for SNAREs and VMATs, with the exception of immunostaining for SNAP-25 and syntaxin1 in 3 of 10 adenocarcinomas. Our findings indicate that SCLC cells are endowed with transporters necessary for intracellular storage of biogenic amines and with proteins required for exocytosis of secretory products. These proteins may be used as markers of differentiation of human lung tumors. Moreover, the presence of VMATs provides the basis for a diagnostic application of biogenic amine-derived tracers in positron emission tomography of SCLC tumors.

Abstract
STUDY OBJECTIVE A rule based on presenting chief complaints can identify patients for a rapid (5-minute) ECG and decrease delays in treatment of patients with acute myocardial infarction (MI). METHODS The presenting chief complaint was electronically collected on all patients treated in a community teaching hospital emergency department. A rule for ordering ECG on patient presentation to the ED was developed from a model set of patients presenting from July through December 1994 (22,717 patients) and then tested on a validation set of patients from January through May 1995 (18,759 patients). Outcome measures (delay in performance of ECG and delay in administration of thrombolytic agents) were prospectively collected on written data sheets before (April 1993-May 1995, n=67) and after (June 1995-March 1997, n=128) implementation of the rule at the study hospital. RESULTS On the model set, 193 patients had the final diagnosis of MI, with 5 chief complaints having the best performance in identifying patients with acute MI and comprising the rapid ECG rule: older than 30 years with chest pain (130 [67.4%] patients); older than 50 years with syncope (5 [1%] patients); weakness (12 [6.2%] patients); rapid heart beat (2 [1%] patients); and difficulty breathing or shortness of breath (20 [10.4%] patients). On the validation set, 142 patients had the final diagnosis of MI, with the rule performing better than chest pain in identifying patients for a "stat" ECG (sensitivity 93.7% versus 67. 4% [95% confidence interval (CI) of the difference, 15.6% to 33.8%]), although a larger percentage of ED patients would receive a stat ECG (7.3% versus 6.3% [95% CI of the difference, 0.7% to 1.7%]). During the model and validation period, 44 (13.1%) of 335 patients with MI received thrombolytic agents. The rule had higher sensitivity on patients with MI treated with thrombolytic agents compared with patients with MI not treated with thrombolytic agents (sensitivity 100% versus 86.4% [95% CI of the difference, 1.7% to 20. 3%] and specificity of 90.4% versus 93.8% [95% CI of the difference, 3.0% to 3.8%]). For the 4-year study period, outcome improved after the implementation of the rule: mean delay in performing ECGs in patients with MI who were administered thrombolytic agents decreased from 10.0 to 6.3 minutes (95% CI of the difference, 1.1 to 6.4), and mean delay in administering thrombolytic agents decreased from 36.9 to 26.1 minutes (95% CI of the difference, 3.5 to 17.7). CONCLUSION Use of a rule based on chief complaints can identify patients with MI for immediate ECG and decrease delays in performing ECGs and administration of thrombolytic agents.

Abstract
Giving an analgesic to patients with right lower quadrant (RLQ) pain causes greater alteration of abdominal signs predictive of appendicitis than placebo. A randomized double-blinded controlled trial of 68 patients who received either tramadol or placebo. Absence or presence of seven abdominal signs (tenderness on light and deep palpation, tenderness in the RLQ and elsewhere, rebound, cough, and percussion tenderness) and pain (100 mm Visual Analog Scale [VAS]) at 0 and 30 minutes were recorded. The predictive value of each physical finding (PF) was measured using an 11-point PF score weighted by likelihood ratios. There was significant reduction in mean VAS of 14.2 mm (95% CI 5.6 to 22.8) in analgesic group versus 6.5 mm (95% CI 1.6 to 11.4) in placebo group. The analgesic group had less normalization of signs as measured by the PF score in all patients [32 of 154 (20.8%) versus 40 of 121 (33.1 %) (P = .031)] and in those with proven appendicitis [4 of 33 (12.1%) versus 10/22 (45.5%) (P = .014)]. Parenteral use of tramadol in emergency department patients with RLQ pain resulted in significant levels of pain reduction without concurrent normalisation of abdominal examination findings indicative of acute appendicitis.

Abstract
OBJECTIVES To test the hypothesis that physician errors (failure to diagnose appendicitis at initial evaluation) correlate with adverse outcome. The authors also postulated that physician errors would correlate with delays in surgery, delays in surgery would correlate with adverse outcomes, and physician errors would occur on patients with atypical presentations. METHODS This was a retrospective two-arm observational cohort study at 12 acute care hospitals: 1) consecutive patients who had an appendectomy for appendicitis and 2) consecutive emergency department abdominal pain patients. Outcome measures were adverse events (perforation, abscess) and physician diagnostic performance (false-positive decisions, false-negative decisions). RESULTS The appendectomy arm of the study included 1, 026 patients with 110 (10.5%) false-positive decisions (range by hospital 4.7% to 19.5%). Of the 916 patients with appendicitis, 170 (18.6%) false-negative decisions were made (range by hospital 10.6% to 27.8%). Patients who had false-negative decisions had increased risks of perforation (r = 0.59, p = 0.058) and of abscess formation (r = 0.81, p = 0.002). For admitted patients, when the inhospital delay before surgery was >20 hours, the risk of perforation was increased [2.9 odds ratio (OR) 95% CI = 1.8 to 4.8]. The amount of delay from initial physician evaluation until surgery varied with physician diagnostic performance: 7.0 hours (95% CI = 6.7 to 7.4) if the initial physician made the diagnosis, 72.4 hours (95% CI = 51.2 to 93.7) if the initial office physician missed the diagnosis, and 63.1 hours (95% CI = 47.9 to 78.4) if the initial emergency physician missed the diagnosis. Patients whose diagnosis was initially missed by the physician had fewer signs and symptoms of appendicitis than patients whose diagnosis was made initially [appendicitis score 2.0 (95% CI = 1.6 to 2.3) vs 6.5 (95% CI = 6.4 to 6.7)]. Older patients (>41 years old) had more false-negative decisions and a higher risk of perforation or abscess (3.5 OR 95% CI = 2.4 to 5.1). False-positive decisions were made for patients who had signs and symptoms similar to those of appendicitis patients [appendicitis score 5.7 (95% CI = 5.2 to 6.1) vs 6.5 (95% CI = 6.4 to 6.7)]. Female patients had an increased risk of false-positive surgery (2.3 OR 95% CI = 1.5 to 3.4). The abdominal pain arm of the study included 1,118 consecutive patients submitted by eight hospitals, with 44 patients having appendicitis. Hospitals with observation units compared with hospitals without observation units had a higher "rule out appendicitis" evaluation rate [33.7% (95% CI = 27 to 38) vs 24.7% (95% CI = 23 to 27)] and a similar hospital admission rate (27.6% vs 24.7%, p = NS). There was a lower miss-diagnosis rate (15.1% vs 19.4%, p = NS power 0.02), lower perforation rate (19.0% vs 20.6%, p = NS power 0.05), and lower abscess rate (5.6% vs 6.9%, p = NS power 0.06), but these did not reach statistical significance. CONCLUSIONS Errors in physician diagnostic decisions correlated with patient clinical findings, i.e., the missed diagnoses were on appendicitis patients with few clinical findings and unnecessary surgeries were on non-appendicitis patients with clinical findings similar to those of patients with appendicitis. Adverse events (perforation, abscess formation) correlated with physician false-negative decisions.

Abstract
BACKGROUND The proportion of emergency department (ED) chest pain patients who undergo an extended "rule out MI (myocardial infarction)" evaluation beyond the ED determines both the quality and cost of patient care. The higher an organization's rate of such evaluations, the lower the average miss rate for MI. Five of the 13 hospitals in the Voluntary Hospital Association Northeast multihospital network implemented ED observation units by June 1997 for outpatient rule out MI evaluations. RESULTS Compared with historical and case controls, the five hospitals with ED observation units had a higher observation rate (16% versus 0% [p < .001] and 2% [p < .001]) and a higher rule out MI evaluation rate (61% versus 46% [p < .01] and 45% [p < .01]), without a significantly higher admission rate (47% versus 46% and 45%). For the three hospitals with observation units that collected charge data during 1997 on a consecutive series of chest pain patients who had negative rule out MI evaluations, charges for patient services were lower for patients evaluated in the ED observation unit ($2,214.80 +/- $80.40) than in the hospital ($5,464.30 +/- $393.60). CONCLUSIONS ED observation units represent a cost-effective restructuring of the diagnostic approach to patients with acute chest pain. In an improvement of quality of patient care, a larger proportion of ED chest pain patients receive an extended evaluation than is possible with hospital admission as the only ED disposition option.

Abstract
STUDY OBJECTIVE We quantify patient risk as related to the presence or absence of the Agency for Health Care Policy and Research (AHCPR) congestive heart failure (CHF) hospital admission criteria. METHODS This was a retrospective observational cohort study at 12 acute care hospitals examining consecutive patients with the final primary diagnosis of CHF. Trained record abstractors blinded to outcome extracted 386 data elements, including 6 AHCPR admission criteria: (1) pulmonary edema (determined by radiograph) or severe respiratory distress (respiration >40 breaths/min), (2) hypoxia (oxygen saturation <90%) not caused by pulmonary disease, (3) significant edema (>/=+2) or anasarca, (4) symptomatic hypotension (<90 mm Hg systolic blood pressure) or syncope, (5) CHF of recent onset, and (6) clinical evidence (chest pain) of myocardial ischemia. The association between admission criteria and mortality rate (30 days, 6 months, and 1 year) was quantified and risk adjusted by stepwise logistic regression analysis. RESULTS Of the 1,674 patients with CHF, 1,340 (80%) were admitted to the hospital. Patients not admitted had a lower mortality rate than admitted patients (30-day mortality rate, 2.1% [95% confidence interval [CI] 0.6 to 3.6] versus 11.5% [95% CI 9.8 to 13.2]; odds ratio 0.20 [95% CI 0.09 to 0.45]). Two of the admission criteria did not correlate with a higher mortality rate: CHF of recent onset and myocardial ischemia. Excluding those 2 criteria, the number of admission criteria present correlated with the patient's probability of hospital admission (P <.001), length of hospital stay (P =.014), and 30-day mortality rate (P <.0001). When zero or 1 admission criteria was present, physician clinical judgment did distinguish patients less likely to die in the subsequent 30 days (1.5% [95% CI 0.2 to 2.8] sent home versus 10.2% [95% CI 8.5 to 11.9] admitted). When 2 or more admission criteria were present, physician clinical judgment did not distinguish patients less likely to die in the subsequent 30 days (18.2% [95% CI 0 to 42.0] sent home versus 19.4% [95% CI 13.6 to 25.2] admitted). CONCLUSION Selected criteria of the AHCPR CHF admission guideline correlate with mortality rate. Combined with physician clinical judgment, they may be useful in the risk stratification of patients with CHF. Selected low-risk patients with CHF identified by the admission criteria who are presently managed in the acute care hospital may be candidates for outpatient management.

Abstract
A reflex algorithm was developed and evaluated for the use of serum cardiac markers for the diagnosis and rule out of acute myocardial infarction (AMI), and risk stratification of unstable angina patients for those who present to emergency departments (ED) with chest pain. The process begins with testing of total CK and myoglobin at admission. Based on these results, the algorithm determines the need for subsequent testing for the CK-MB isoenzyme and cardiac troponin I (cTnI). The algorithm also directs the need for further blood collection and cardiac marker testing at 4, 8, and 12 h after presentation. A total of eleven stopping points were identified. For some of these stopping points, the algorithm concluded that further blood collections and testing was unnecessary and redundant. The algorithm was retrospectively evaluated on 101 non-consecutive chest pain patients who presented to the EDs at three hospitals. For the AMI group (n=34), six of nine possible different stopping points were reached: 64.7% of cases were diagnosed with the first sample at admission, an additional 32.3% after 4 h, and 2.9% at 8 h. The 12-h sample was not necessary for any of the AMI patients. For the non-AMI group (n=67), most reached the stopping point of no cardiac injury or risk. There were five unstable angina patients who had minor myocardial damage on the basis of a marginally increased cTnI. Of these, one patient subsequently suffered AMI, and three others required angioplasty or bypass surgery. Compared to performing four tests on all patient samples, the reflex algorithm would have reduced the number of necessary tests from 442 to 130 (71% reduction) for AMI patients, and 871 to 469 (46% reduction) for non-AMI patients, if prospectively implemented.

Abstract
Emergency medicine (EM) will change over the next 20 years more than any other specialty. Its proximity to and interrelationships with the community, nearly all other clinicians (physicians and nonphysicians), and scientific/technologic developments guarantee this. While emergency physicians (EPs) will continue to treat both emergent and nonemergent patients, over the next decades our interventions, methods, and place in the medical care system will probably become unrecognizable from the EM we now practice and deliver. This paper, developed by the Society for Academic Emergency Medicine (SAEM) Task Force on Academic Emergency Medicine's Future, was designed to promote discussions about and actions to optimize our specialty's future. After briefly discussing the importance of futures planning, it suggests "best-case," "worst-case," and most probable future courses for academic EM over the next decades. The authors predict that EPs will practice a much more technologic and accurate form of medicine, with diagnostic, patient, reference, and consultant information rapidly available to them. They will be at the center of an extensive consultation network stemming from major medical centers and the purveyors of a sophisticated home health system, very similar to or even more advanced than what is now delivered on hospital wards. The key to planning for our specialty is for EM organizations, academic centers, and individuals to act now to optimize our possible future.

Abstract
OBJECTIVE To describe interobserver variability among emergency medicine (EM) faculty when using global assessment (GA) rating scales and performance-based criterion (PBC) checklists to evaluate EM residents' clinical skills during standardized patient (SP) encounters. METHODS Six EM residents were videotaped during encounters with SPs and subsequently evaluated by 38 EM faculty at four EM residency sites. There were two encounters in which a single SP presented with headache, two in which a second SP presented with chest pain, and two in which a third SP presented with abdominal pain, resulting in two parallel sets of three. Faculty used GA rating scales to evaluate history taking, physical examination, and interpersonal skills for the initial set of three cases. Each encounter in the second set was evaluated with complaint-specific PBC checklists developed by SAEM's National Consensus Group on Clinical Skills Task Force. RESULTS Standard deviations, computed for each score distribution, were generally similar across evaluation methods. None of the distributions deviated significantly from that of a Gaussian distribution, as indicated by the Kolmogorov-Smirnov goodness-of-fit test. On PBC checklists, 80% agreement among faculty observers was found for 74% of chest pain, 45% of headache, and 30% of abdominal pain items. CONCLUSIONS When EM faculty evaluate clinical performance of EM residents during videotaped SP encounters, interobserver variabilities are similar, whether a PBC checklist or a GA rating scale is used.

Abstract
BACKGROUND Since 1993 the 13 VHA Southern New England (VHA-SNE) hospitals have been engaged in a regionally sponsored initiative to analyze and improve selected clinical processes. Nine of these hospitals have chosen to participate in an initiative in which observation units were postulated to offer a tool for improving the care of patients with chest pain-the VHA initiative to Implement Chest Pain Treatment in Observation Units. THE FIVE PHASES In phase 1 of the initiative, the VHA-SNE's Clinical Benchmarking Work Group reviewed the medical literature, which confirmed longstanding systemic and pervasive problems in the evaluation of chest pain patients. The work group's preferred practice was the outpatient "rule out myocardial infarction [MI] evaluation" program during monitored observation; serial testing can accurately diagnose low- and moderate-probability patients with MI. In Phase 2 the study group surveyed the emergency departments in the nine hospitals, discovering significant variation in admission rates and practice patterns. During phase 3 the work group identified a health care organization demonstrating best-practice performance--one of the few hospitals in the nation with an operational outpatient "rule out MI evaluation" program. A team site-visited that organization and recorded information about its structure and processes. VHA-SNE then published a monograph that identified its current performance, described the best-practice approach, offered strategies to implement the model program, and analyzed the financial implications and return on investment. In phase 4 a pilot hospital implemented the model program, which in phase 5 is being extended to the other hospitals represented in the work group. Information regarding protocols, lessons learned, and barriers to implementation was freely provided.

Abstract
The aim of this study was to study a possible new non-aluminum phosphate-binder to limit hyperphosphatemia in patients with renal failure. Zirconyl chloride octahydrate was evaluated as a dietary phosphate binder in rats. Aluminum chloride hexahydrate was used as a reference. Animals were divided into six groups (6 animals per group): One - control group (C), two - aluminum groups (Al1 and Al2) and three - zirconium groups (Zr1, Zr2 and Zr3) receiving different doses of zirconyl chloride octahydrate. Urines were collected during the experimental period. At the end of the treatment, the animals were sacrified and plasma and different organs were collected (liver, spleen, kidneys, brain and femur). Determination of phosphorus and calcium levels in plasma indicated that zirconyl chloride octahydrate yielded as good results as aluminum chloride hexahydrate did. Zirconyl chloride octahydrate significantly (p<0.01) reduced bone phosphorus burden. Urinary excretion of phosphorus indicated a severe phosphorus depletion in all treatments. Not even traces of zirconium could be determined in the different tissues, in urines or in plasma. Consequently, it is important to carry out experiments with zirconium compounds in order to develop non-aluminum-containing phosphate binders.

In vitro and in vivo evaluation of potential aluminum chelators. VETERINARY AND HUMAN TOXICOLOGY 1995; 37:455-61. [PMID: 8592836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 01/31/2023]
Abstract
The potential for aluminium (Al) chelation by different compounds was determined using 2 in vitro techniques. The formation of stable complexes with Al in an aqueous solution was evaluated using pulse polarography. This technique allowed the influence of temperature and calcium (Ca) to be studied for each compound. Certain compounds (EDDHA, HAES, citric acid and HBED) showed great chelation in the absence of Ca2+ at a temperature of 37 +/- 1 C. An ultrafiltration technique combined with Al determination by atomic emission spectroscopy allowed the efficiency of different substances to complex Al that were previously bound to serum proteins to be estimated. The kinetics of chelation and minimum efficient concentration have been determined for all products studied. EDDHA had chelation potential similar to DFO. The real efficacies of the compounds were studied in vivo to compare the effectiveness of repeated administrations of the best chelating agents (EDDHA, DFO, HAES and tartaric acid) on the distribution and excretion of Al after repeated i.p. administrations to rats. Intraperitoneal EDDHA significantly increased urinary metal (Al, Ca, Cu, Fe and Zn) excretion. These excretions may be correlated to a renal toxic potential property.

Abstract
The aim of this study was to highlight a possible new non-aluminum phosphate-binder to limit hyperphosphatemia in patients with renal failure. Lanthanum chloride hydrate was evaluated as a dietary phosphate binder in rats. Aluminum chloride hexahydrate was evaluated as a reference. Animals were divided in five groups (6 animals per group): 1 control group (C), 2 aluminum groups (Al1 and Al2), receiving different doses of aluminum chloride hexahydrate and 2 lanthanum groups (La1 and La2), receiving different doses of lanthanum chloride hydrate. During the treatment, urine and stools were collected. At the end of the treatment animals were sacrificed and plasma and different organs were collected (liver, spleen, kidneys, brain and femur). To highlight the possible transfer of lanthanum in rat tissues, a long-term (100 days) study was carried with a high dose. At the end of the treatment, lanthanum determinations were carried out on several tissues (liver, spleen, kidneys, brain, femur and lungs). Determinations of phosphorus and calcium levels in plasma indicated that lanthanum chloride hydrate showed as good results as aluminum chloride hexahydrate. Lanthanum chloride hydrate significantly (p < 0.01) reduced the bone phosphorus burden. Decreases of urinary excretion and increases in fecal excretion of phosphorus indicated a severe phosphorus depletion in all treatments (Al and La). Unfortunately, in the long-term study, lanthanum traces could only be determined in the different tissues but not in plasma. However, in comparison with the equivalent aluminum treatment, the transfer of lanthanum was less important than aluminum transfer. Consequently, lanthanum could provide a possible alternative to aluminum.

Abstract
Since desferrioxamine exhibits toxic effects, the possible use of several other therapeutic agents in acute aluminum intoxication has been investigated in this study. The potential for the chelation of aluminum (Al) by different compounds has been first determined using two in vitro techniques. The formation of stable complexes with Al in an aqueous solution has been evaluated by using pulse polarography. This technique allows the influence of temperature and of calcium (Ca) to be studied for each compound. Certain compounds (HEDTA, DTPA) showed extensive chelation in the presence of Ca2+ at a temperature of 37 +/- 1 degree C. An ultrafiltration technique combined with Al determination by atomic emission spectroscopy (A.E.S.) has allowed the ability of different substances to complex Al that was previously bound to serum proteins, to be estimated. The kinetics of chelation and the minimum efficient concentration have been determined for all of the products studied. The real efficacies of the compounds were studied by in vivo investigations to compare the effectiveness of the best chelating agents (DFO, HEDTA and EDTA) on the distribution and excretion of Al, after repeated i.p. administration to rats. HEDTA shows a chelation potential as widely active as the DFO potential.

Abstract
STUDY OBJECTIVE To examine patients with abdominal pain for changes in probability of appendicitis during observation. STUDY DESIGN Retrospective cohort study. SETTING University-affiliated community hospital. METHODS 252 patients with abdominal pain who were examined underwent short-term (10.4 hours) observation (95% confidence interval [CI], 8.7, 12.1) before the decision to operate during a one-year period. Alvarado's scoring system and a probability-of-diagnosis nomogram were used to assign scores and estimate probability of appendicitis. MEASUREMENTS AND RESULTS In the study group, mean score of patients with appendicitis increased after observation from 6.8 (95% CI, 6.2, 7.4) to 7.8 (95% CI, 7.3, 8.3), corresponding to a change in probability of appendicitis from 50% to 65%. Mean score of patients without appendicitis decreased from 3.8 (95% CI, 3.5, 4.1) to 1.6 (95% CI, 1.58, 1.62), corresponding to a change in probability from 35% to 22%. The difference between mean scores for patients with and without appendicitis increased from 2.6 (95% CI, 2.0, 3.2) to 6.2 (95% CI, 6.15, 6.25) during observation. The study group initially had intermediate probability of appendicitis (score, 4.35; 95% CI, 4.04, 4.66) compared with high probability for patients who went directly to surgery after their initial evaluation (63 patients; score, 7.59; 95% CI, 7.05, 8.73) and low probability for patients with abdominal pain who were sent home after their initial evaluation without observation or surgery (2,097 patients; score, 1.87; 95% CI, 1.48, 2.26). CONCLUSION In this group of patients with intermediate initial probability of appendicitis, observation improved the ability to distinguish patients with from those without appendicitis.

Abstract
Three hundred fifty patients in an observation unit attached to an emergency department received diagnostic workup of nine critical diagnostic syndromes (abdominal pain, flank pain, headache, possible cerebrovascular accident, chest pain, dizziness or syncope, head injury, seizure, multiple trauma). The decision to hospitalize for acute care after observation for 11.1 +/- 3.9 hours was examined. The objective diagnosis-related group (DRG) criteria for admission were compared retrospectively with the physician's clinical judgment of need for hospitalization. Clinical outcome was used to establish the correctness of the decision to hospitalize. Clinical judgment was compared with objective DRG criteria for reliability in predicting the presence of serious pathology necessitating acute care hospitalization; respective values were sensitivity, 100% vs 76%; specificity, 86% vs 80%; positive predictive value, 75% vs 62%; and negative predictive value, 100% vs 89%. The difference between the sensitivity of the two admission criteria was highly significant (P less than 10(-8); chi 2, 26.12). We conclude that the physician's clinical judgment outperforms DRG objective criteria in identifying which patients with critical diagnostic syndromes need acute care hospitalization for emergency medical or surgical therapy.

Abstract
Psychological well-being is based on multiple factors, one of which is satisfaction with physical appearance. The use of cosmetics is helpful for many women, as has been shown in psychological studies and implied by market sales. People with obvious cutaneous defects (e.g., port-wine stains, pigmentary disorders) may suffer a range of distress reactions, including diminished self-esteem. Specially designed camouflage cosmetics are an ideal adjunct to other therapies for successful treatment of such skin conditions. New products are appealing because they are readily available, safe, and inexpensive. To enjoy optimum use of these products, patients should be assessed and advised in a professional setting. The results are extremely gratifying for both patients and physicians.
