Our purpose was to obtain epidemiological measures of the association between habitual alcohol consumption, alcohol consumption before the event and alcohol abuse/dependence, and emergency room (ER) attendance compared to the general population in Pachuca-Hidalgo, a city located in the central area of Mexico. The study was a population based case-control design. Data consisted of breath samples to estimated blood alcohol concentration, as well as an interviewer-administered questionnaire, collected on a 24-hr basis, during the entire week, in each of the three main ERs of Pachuca. Cases were all patients who visited the three main hospitals ERs during the study period, classified according to their status as an injured or noninjured (medically ill) patient (n = 1511). The general population sample (n = 920) serves as a comparison group for both types of patients. Injured patients in the ER sample were significantly more likely to report high frequency/high quantity of drinking during the last 12 months than the general population [odds ratio and 95% confidence intervals = 5.55 (1.72-17.97)] and to report drinking within 6 hr before the injury. These relationships did not hold for noninjured patients. Both types of patients were more likely to report high frequency of drunkenness during the preceding 12 months, to be positive for alcohol dependence and to report drug use. We found in the city of Pachuca, a large relationship between habitual alcohol consumption and ER injuries. These findings support associations of alcohol consumption and admission to an emergency room found in ER and general population studies in other countries. Due to the increases in the risk found for abuse/dependent in both injured and noninjured patients, they both would benefit with a brief intervention strategy for reducing their alcohol consumption.  相似文献

A phase II pilot study of bendamustine as salvage treatment in patients with advanced breast cancer was performed to determine the objective response rates and make further observations on the toxicity of this drug. A group of 37 patients, pretreated with chemotherapy for advanced disease, entered the trial. Treatment consisted of 150 mg/m2 bendamustine on days 1 and 2 of a 4-week treatment course. Patients continued to receive treatment until complete remission and then two further courses, until tumour progression or unacceptable toxicity ensued. A total of 36 patients received at least one treatment course and were assessable for toxicity; 33 patients were evaluable for treatment results. Dose-limiting grade 3 and 4 WHO toxicity occurred in 5 and 3 patients respectively; 27% of patients entered complete or partial tumour remission. The median time to tumour progression was 2 months with a range of 1-14 months. The efficacy of bendamustine was apparently independent of pretreatment with anthracyclines, suggesting a lack of cross-resistance between bendamustine and anthracyclines. It can be concluded that bendamustine in the dose and application schedule used here is active in the salvage therapy of women with advanced breast cancer. The toxicity was acceptable. Future studies have to confirm the data of this pilot trial and to define the role of bendamustine in the combination chemotherapy of metastatic breast cancer that has been suggested by previous trials.  相似文献

A tubular bioassay was used to measure analytically the local production and concentration of the antifungal Trichoderma secondary metabolite 6-n-pentyl-2H-pyran-2-one (6PAP) at the Trichoderma antagonist/pathogen interface. 6PAP levels significantly increased in the presence of the pathogen Botrytis cinerea, typically 300-700%, and were highest near the pathogen source. The level of response for a particular Trichoderma isolate was found to vary with the test organism used. Two products produced by biotransformation of 6PAP by B. cinerea in response to the interaction were also detected.  相似文献

Compared evaluations by psychologists, psychiatrists, a psychiatric team, and psychiatric residents of 258 16–76 yr old patients in an inner-city hospital emergency room. Both patient presentation and medical and psychiatric evaluations did not vary over time. Other than the finding that psychologists initiated evaluations sooner and hospitalized fewer patients than did psychiatrists, there were no significant temporal or dispositional differences in decisions made between psychologists and the other evaluators. Results are consistent with previous findings that more extensive evaluations lead to fewer recommended hospitalizations. Results also suggest disposition decisions are affected by training, and psychologists tend to place more responsibility on the patient and/or the patient's family than do psychiatrists.

OBJECTIVE: To compare the use of emergency medical care by elders in the United States in 1995 with that previously described for 1990. METHODS: A computerized billing database of 88 EDs in 21 states was retrospectively reviewed for 1995, comparing elder and nonelder patients, estimating national use of emergency medical services by elders, and comparing the 1995 data with previously published results for 1990. RESULTS: From 1990 to 1995, the number of ED visits in the United States increased from 92 million to 100 million. The number of visits made by patients aged 65 years or older increased from 13,639,400 (15%) to 15,666,300 (15.7%), but this increase did not reach statistical significance (p = 0.17). The admission rate for elder ED patients increased from 32% to 46% over the five-year interval (p<0.01). This represents more than 7 million hospital admissions for elder patients in 1995. The rate of intensive care unit (ICU) admission for elders decreased from 7% to 6% over the five-year interval (p = 0.56), compared with 1.3% for nonelder patients for both years. Thirty percent of elder ED patients arrived by ambulance in 1990, compared with 33% in 1995 (p = 0.02). Based on 1995 data, elders comprised 39% of patients arriving by ambulance [odds ratio (OR) 4.75, 95% confidence interval (CI) = 4.71 to 4.79], 43% of all admissions (OR 6.59, 95% CI = 6.54 to 6.64), and 47% of ICU admissions (OR 5.00, 95% CI = 4.91 to 5.09). The comparable ORs in 1990 were 4.4, 5.6, and 5.5, respectively. CONCLUSIONS: From 1990 to 1995, the overall number of ED visits increased. The rate of increase was somewhat greater for elder patients. The use of ambulance services also disproportionately grew among elder patients, as did the rate of hospital admission. The overall rate of ICU admission was stable, but actually fell modestly for elder patients. Of these changes, only the increase in the rate of hospital admission for elders reached statistical significance.  相似文献

PURPOSE: The Southwest Oncology Group (SWOG) coordinated an Intergroup study with the participation of Radiation Therapy Oncology Group (RTOG), and Eastern Cooperative Oncology Group (ECOG). This randomized phase III trial compared chemoradiotherapy versus radiotherapy alone in patients with nasopharyngeal cancers. MATERIALS AND METHODS: Radiotherapy was administered in both arms: 1.8- to 2.0-Gy/d fractions Monday to Friday for 35 to 39 fractions for a total dose of 70 Gy. The investigational arm received chemotherapy with cisplatin 100 mg/m2 on days 1, 22, and 43 during radiotherapy; postradiotherapy, chemotherapy with cisplatin 80 mg/m2 on day 1 and fluorouracil 1,000 mg/m2/d on days 1 to 4 was administered every 4 weeks for three courses. Patients were stratified by tumor stage, nodal stage, performance status, and histology. RESULTS: Of 193 patients registered, 147 (69 radiotherapy and 78 chemoradiotherapy) were eligible for primary analysis for survival and toxicity. The median progression-free survival (PFS) time was 15 months for eligible patients on the radiotherapy arm and was not reached for the chemo-radiotherapy group. The 3-year PFS rate was 24% versus 69%, respectively (P < .001). The median survival time was 34 months for the radiotherapy group and not reached for the chemo-radiotherapy group, and the 3-year survival rate was 47% versus 78%, respectively (P = .005). One hundred eighty-five patients were included in a secondary analysis for survival. The 3-year survival rate for patients randomized to radiotherapy was 46%, and for the chemoradiotherapy group was 76% (P < .001). CONCLUSION: We conclude that chemoradiotherapy is superior to radiotherapy alone for patients with advanced nasopharyngeal cancers with respect to PFS and overall survival.  相似文献

Between February 1985 and October 1989, 26 patients previously treated for metastatic breast cancer received oral tegafur, at a median daily dose of 1200 mg. Of these, 21 were evaluable for response. The overall response rate was 29%; six (two in lungs, two in skin and two in lymph nodes) of 44 evaluable lesions (14%) responded to therapy. Haematological toxicity was mild, and no other dose-limiting toxicity was seen. The data indicate some activity in heavily pretreated metastatic breast cancer even after previous 5-FU therapy.  相似文献

A retrospective survey over one year of a hospital emergency room population, seen at an oral and maxillofacial surgery clinic, found 271 patients (4.6% of the total population) with dentoalveolar injuries. A very large number of injuries occurred to children between the ages of 0 and 5 years (42.1%), and there was a significant number of injured patients in the adult population (19.1%). The ratio of male to female was 1.9:1. The leading cause of injury was falls (59.8%). The largest number of injuries was seen during summer. The diagnoses were lateral luxation (27.3%), concussion (17.3%), exarticulation (14.3%), tooth fracture (12.5%), intrusive luxation (11.1%), fracture of alveolar process (7.4%), extrusive luxation (3.7%), and cases with more than one diagnosis (6.3%). Most of the involved teeth were maxillary central incisors, in both dentitions.  相似文献

All patients with presumed coronary problems seen at the Chaim Sheba Medical Center during a one-year period were followed up. The fate of those who were not hospitalized and the factors contributing to the two types of erroneous decisions, ie, refusing hospitalization to those needing it and unnecessary hospitalization of others, were evaluated. Approximately 50% of the patients were not admitted. Myocardial infarctions were later diagnosed in 6% of these patients. Another 8% were eventually categorized as other cardiac emergencies. Ten percent of all patients subsequently diagnosed as having myocardial infarctions were not admitted. On the other hand, 56% of the patients whose cases were later not considered to have been emergencies were hospitalized unnecessarily. Previous hospitalization for cardiac disease played a major role in making an error of both types. Other factors influencing the physician's decision regarding the patients' disposition included their age, sex, ethnic origin, and the findings from the emergency room electrocardiogram.  相似文献

PURPOSE: To evaluate the efficacy and safety of docetaxel in patients with paclitaxel-resistant metastatic breast cancer (MBC). PATIENTS AND METHODS: Docetaxel (100 mg/m2) was administered every 3 weeks to 46 patients registered at four centers. Patients had previously received < or = two chemotherapy regimens for MBC. All patients had progressive disease while receiving paclitaxel therapy. Treatment was repeated until there was evidence of disease progression or for a maximum of three cycles after best response. RESULTS: Objective responses were seen in eight of 44 assessable patients (18.1%; 95% confidence interval [CI], 6.7% to 29.5%). Seven patients had partial responses and one patient responded completely. Response rates were not significantly different by previously received paclitaxel dose or resistance. No responses were seen in 12 patients who had previously received paclitaxel by 24-hour infusion, but the response rate in 32 patients who had received paclitaxel by 1- to 3-hour infusion was 25%. The median response duration was 29 weeks and the median time to disease progression was 10 weeks. Median survival was 10.5 months. Clinically significant (severe) adverse events included neutropenic fever (24% of patients), asthenia (22%), infection (13%), stomatitis (9%), neurosensory changes (7%), myalgia (7%), and diarrhea (7%). CONCLUSION: Docetaxel is active in patients with paclitaxel-resistant breast cancer, particularly in those who failed to respond to brief infusions of paclitaxel. Response rates were comparable to or better than those seen with other therapies for patients with paclitaxel-resistant MBC. This confirms preclinical studies, which indicated only partial cross-resistance between paclitaxel and docetaxel.  相似文献

Rendu-Osler-Weber's disease or Hereditary Hemorrhagic Telangiectasia (HTT) is an autosomal dominant hereditary clinical entity characterized by the presence of telangiectasias on skin, mucous membranes and internal organs. The incidence of hepatic, pulmonary or cerebral complications justifies an early diagnostic. A familiar study of patients previously diagnosed of HTT in our hospital was made, establishing a protocol for the identification of asymptomatic or pauci-symptomatic cases. Fourteen patients were studied: 6 with a previous diagnostic, and 8 familiar contacts. Penetrance was of 85%. Epistaxis (80%) and telangiectasias on skin were the most frequent clinical findings. The visceral lesions found were gastrointestinal (28%), hepatic (15%), urological (15%) and pulmonary (7%). All patients were included in an hepatitis B virus vaccination program. It was also made a morphological study with Werhoeff's staining of the elastic layer, that allowed to distinguish both arterial and venous alterations.  相似文献

Malignant gliomas are rather refractory to current therapeutic approaches including surgery, radiotherapy, chemotherapy and immunotherapy. Acquired alterations in the pathways required for apoptotic cell death are thought to be responsible to the failure of glioma to respond to therapy. Here we have examined the expression of several proteins involved in the susceptibility to apoptosis in 20 human gliomas, including the BCL-2 family proteins BCL-2, BCL-X, BAX and MCL-1, as well as p53 and RB. Most gliomas expressed several BCL-2 family proteins. There was good correlation between expression of the functional antagonists, BCL-2/BCL-X and BAX, suggesting that changes in the BCL-2+BCL-X/BAX ratio are not responsible for the differential response of glioma patients to chemotherapy. The immunochemistry data were also analysed in regard to response to therapy and clinical outcome. All patients had cytoreductive surgery and received radiotherapy and nitrosourea-based adjuvant chemotherapy. There was no prominent association of outcome with the expression patterns of p53, RB, BCL-2, BCL-X or BAX. We find, however, that expression of the MCL-1 protein is associated with early tumour recurrence and shorter survival in this group of glioma patients. This preliminary observation will have to be confirmed in a larger independent sample of glioma patients.  相似文献

Deep vein thrombosis (DVT) and pulmonary embolism (PE) are major complications associated with total knee arthroplasty. The American College of Chest Physicians recommends twice-daily, fixed-dose low-molecular-weight heparin (LMWH) as routine prophylaxis in this patient population. This study represents a cost analysis of ardeparin and enoxaparin, the two LMWHs currently available for this indication in the United States. Costs for treating DVT, PE, and major bleeding episodes were derived from values reported in the literature. Both ardeparin and enoxaparin were found to produce significant cost savings when used routinely as DVT prophylaxis after knee replacement surgery compared with no prophylaxis. Based on the currently available data, enoxaparin 40 mg once daily appears to be the least costly LMWH for routine pharmacoprophylaxis of DVT in patients undergoing knee replacement surgery.  相似文献

The objective of this study was to investigate the association of the oxygen tension in the periodontal pockets with clinical parameters of gingival inflammation of the maxillary anterior teeth of 32 patients. The pocket oxygen tension (pO2) was measured by a polarographic method with electronic compensation for temperature change. The oxygen saturation of hemoglobin (SO2) in the gingiva was determined with tissue reflectance spectrophotometry. Gingival crevicular fluid flow (GCF) was measured with electronic impedance. No significant association was found between pocket pO2 and the modified gingival index, the plaque index, and GCE Pocket pO2 showed significant correlation with probing depth (r = -0.57, P = 0.0005). Significant correlation was observed between pocket pO2 and gingival SO2 (r = 0.69, P < 0.0001). When all variables were entered into a multiple regression model, only gingival SO2 had a significant independent effect on the pocket pO2 (P = 0.0005). These results indicate that the oxygen sufficiency in the gingiva has a significant independent influence on the pocket oxygen tension. These studies provide the basis for understanding the oxygen tension in the periodontal pocket, which likely is a major determinant of the subgingival microflora. The studies may also lead to the development of methods for diagnosing and monitoring periodontal diseases.  相似文献

The three more common illnesses diagnosed in the sample of 314 emergency room patients were (in order of frequency) affective disorder (N = 135), alcoholism (N = 112), and antisocial personality (N = 57). This study describes the occurrence and frequency of affective disorders and evaluates the relative usefulness of three separate sets of diagnostic criteria for the depressive phase of the illness, which are considered in three self-evident, mutually exclusive groups, the definition of which depends on chronology of onset in relation to other diagnoses. Findings show a 3:2 ratio of primary affective disorder to secondary affective disorder. The 112 diagnoses of alcoholism were based on defined criteria that separated "definite" (N = 102) from probable (N = 10) alcoholism. A high incidence of secondary affective disorder (38%) in patients with a first diagnosis of alcoholism is noted. The third most common diagnosis, antisocial personality, was based on defined criteria requiring a specified number of manifestations both before and after age 15 years. Only 11% of the antisocial personality patients received a single diagnosis of antisocial personality. An additional diagnosis of alcoholism occurred in 61%. Besides antisocial symptoms, the 57 patients reported 74 different nonantisocial symptoms, supporting the conclusion that antisocial personality patients may be as susceptible to neurotic and psychotic symptoms as other patients.  相似文献

BACKGROUND: Most patients with advanced ovarian cancer will relapse following platinum-based combination chemotherapy and be considered for second-line treatment. Gemcitabine, a nucleoside analogue, is active against a range of solid tumors. This phase II study investigated the activity of single-agent gemcitabine in patients with recurrent ovarian cancer. PATIENTS AND METHODS: Thirty-eight patients with FIGO stage III (34%) or IV (64%) ovarian cancer who were previously treated with platinum-containing regimens were enrolled. Patients received 1200 mg/m2 gemcitabine on days 1, 8 and 15 of a 28-day cycle. RESULTS: Patients completed an average of 3.6 cycles. Two complete and three partial responses were seen in 36 evaluable patients, for an overall response rate of 13.9% (95% CI: 4.7%-29.5%). The median survival time was 6.7 months. Toxicities were generally mild. The most common were grade 3-4 neutropenia and grade 3 leukopenia reported in 23.7% and 10.5% of patients, respectively. One patient had grade 4 pulmonary toxicity. CONCLUSION: Single-agent gemcitabine is active and well tolerated in patients with recurrent ovarian cancer.  相似文献
