Abstract
INTRODUCTION Over the past decade, there has been a sharp increase in the number of newly identified synthetic drugs. These new drugs are often derivatives of previously abused substances but have unpredictable toxicity. One of these drugs is gacyclidine, a derivative of phencyclidine (PCP). Gacyclidine has been studied as a neuroprotective agent in trauma and as a therapy of soman toxicity. There are no previous reports of its use as a drug of abuse. CASE REPORTS During a two-month period in the summer of 2013, a series of patients with severe agitation and end-organ injury were identified in an urban academic Emergency Department (ED). A urine drug of abuse screen was performed on all patients, and serum samples were sent for comprehensive toxicology analysis. A total of five patients were identified as having agitation, rhabdomyolysis, and elevated troponin (Table 1). Three of the five patients reported use of methamphetamine, and all five patients had urine drug screens positive for amphetamine. Comprehensive serum analysis identified methamphetamine in three cases, cocaine metabolites in one case, and a potential untargeted match for gacyclidine in all five cases. No other drugs of abuse were identified. DISCUSSION This is the first series of cases describing possible gacyclidine intoxication. The possible source of the gacyclidine is unknown but it may have been an adulterant in methamphetamine as all patients who were questioned reported methamphetamine use. These cases highlight the importance of screening for new drugs of abuse when patients present with atypical or severe symptoms. Gacyclidine has the potential to become a drug of abuse both by itself and in conjunction with other agents and toxicity from gacyclidine can be severe. It is the role of the medical toxicology field to identify new agents such as gacyclidine early and to attempt to educate the community on the dangers of these new drugs of abuse.

Abstract
388 Background: Mutations in the KRAS oncogene are present in approximately 30-40% of colorectal adenocarcinomas. Wild-type (WT) KRAS mutational status is recognized to be predictive of tumor response with epidermal growth factor receptor-directed therapies such as cetuximab and panitumumab. Studies evaluating the prognostic value of KRAS status in localized (stage II and III) disease have been contradictory. The prognostic value in metastatic disease, either synchronous or metachronous, is less studied. Methods: Consecutive patients with metastatic colorectal adenocarcinoma underwent tumor testing for KRAS exon 2 (codons 12 and 13) mutations by polymerase chain reaction amplification and direct nucleotide sequencing. The clinical characteristics, treatments, and outcomes of these patients were then retrospectively analyzed, stratified by synchronous or metastatic disease and KRAS mutational status (WT or mutated). Results: For synchronous metastatic disease, KRAS WT patients (n = 39) had median overall survival (OS) of 34.3 months (95% CI, 21.8-58.3). KRAS mutated patients (n = 24) had median OS of 40.3 months (95% CI, 25.7-51.0; log-rank p = 0.55). By Kaplan-Meier survival analysis, 3-year OS was 48.9% (95% CI, 31.1-64.5) for KRAS WT and 51.1% (95% CI, 27.6-70.6) for KRAS mutated patients. Five-year OS was 27.8% (95% CI, 11.6-46.8) for KRAS WT and 9.7% (95% CI, 0.7-33.8) for KRAS mutated patients. For metachronous metastatic disease, from time of development of metastasis, KRAS WT patients (n = 29) had median OS of 33.2 months (95% CI, 28.3-40.7). KRAS mutated patients (n = 16) had median OS of 53.0 months (95% CI, 27.8-not applicable; log-rank p = 0.29). By Kaplan-Meier survival analysis, 3-year OS was 40.1% (95% CI, 19.9-59.7) for KRAS WT and 57.3% (95% CI, 25.0-80.0) for KRAS mutated patients. Five-year OS was 22.9% (95% CI, 7.6-43.2) for KRAS WT and 28.6% (95% CI, 1.7-68.1) for KRAS mutated patients. Conclusions: KRAS mutation status does not influence overall survival in either synchronous or metachronous metastatic colorectal adenocarcinoma. No significant financial relationships to disclose.

Abstract
Dental care can occur within or outside the formal health-care system. We hypothesized that certain subject characteristics would partly explain one type of dental self-care, non-professional extractions. A representative sample of diverse groups of dentate adults was studied. In-person interviews and clinical examinations were conducted at baseline, 24, 48, and 72 months, with semi-annual telephone interviews in between. Of 699 participants, 291 (42%) reported loss of at least one tooth, of whom 42 (14% of those with tooth loss) reported having lost the tooth at a place other than a health-care facility. Ninety-four percent of non-professionally lost teeth were self-extracted; relatives extracted the remainder. Fifty-eight percent of these teeth were deliberately removed; the remainder came out while subjects were eating or brushing their teeth, or due to injury. Attachment loss and mobility at previous examination were consistent with the occurrence of non-professional extraction. The incidence magnitude was substantive and persistent throughout follow-up.

Abstract
The current study used a cohort-sequential design to examine age-related changes in health-relevant beliefs from the middle school years through age 37 in a large, midwestern, community sample (N=8,556). Results suggest systematic age-related changes such that beliefs in the personalized risks of smoking declined in middle school and then increased, beliefs in generalized health risks increased beginning in the middle school years, and values placed on health as an outcome decreased in the high school years and then increased. These findings suggest that intervention programs must counter declining personalized risk perceptions among middle school students and declining values placed on health among high school age students.

Abstract
A number of clinical coding and vocabulary schemes are in use in healthcare enterprises today. Most of them are weak in light of the qualities that characterize adequate controlled medical terminologies, as outlined in Part One of this review. Here we look at the major code and terminology sets with a critical eye, as well as suggest practical steps to enable health industry information system purchasers and users to move forward with their effort to use common terminology to improve the quality, service, and knowledge in their enterprise.

Abstract
It has become abundantly clear that standards of recording clinical terms in human-readable, computer-processable format are indispensable. Controlled medical terminology is the missing link in health information standards (in fact, medical terminology can be viewed as the mother of all standards); its absence interferes with the business of healthcare and impedes the core processes of healing and maintaining health. Medicine has lacked the controlled common medical vocabulary that would enable universal sharing of data at the point of care and ensure reliable information for determining health intervention effectiveness. Simple clinical and code content alone has proven insufficient for healthcare enterprises to successfully manage the terminology problem; the "lexical runtime engine," formerly called a vocabulary server (VOSER), which manages the vocabulary ontology and serves up the relevant vocabulary to users of applications in the clinical environment, has recently become a reality.

Abstract
OBJECTIVE To determine the physiological consequences of acute CO exposure from cooking in snow caves at 3,200 m. We hypothesized that ambient CO and serum carboxyhemoglobin (COHb) levels would increase and that even low levels of COHb would be associated with symptoms of CO poisoning at high altitude. METHOD This was a prospective observational study. Twenty-two healthy volunteers age 18 years or older were recruited during a winter camping trip at 3,200 m. Subjects filled out symptom questionnaires, and heart rate (HR), oxygen saturation (SaO2), serum COHb, and ambient CO were all measured before and after cooking inside snow caves. RESULTS Median age of subjects was 32 years, and 87% were male. The median ambient CO level increased by 17 ppm (IQR, 2-27 ppm), P = .005. Mean serum COHb level rose from 0.3% (IQR, 0.2%-0.4%) to 1.2% (IQR, 0.7%-2.6%) after cooking, for a difference of 1% (IQR, 0.4%-2.3%), P < .001. There were no differences in symptom scores before and after cooking, and there was no significant effect on HR or SaO2. CONCLUSION A single exposure to CO at 3,200 m increases ambient CO and COHb but not to clinically important levels. Further studies are needed to examine the risks of longer exposures at higher altitudes.

Abstract
OBJECTIVE There is a paucity of evidence demonstrating that emergency department (ED) ultrasound changes clinical practice in trauma patients. We hypothesized that the presence of ultrasound would affect clinical decision making as evidenced through abdominal computed tomographic (CT) scan use in blunt multiple trauma patients. METHODS This study used a prospective randomized format in an urban county ED with Level II trauma center status (ED census, 72,000 patients per year). Participants were patients with multiple blunt injuries meeting trauma center triage criteria. Patients were randomized to receive either abdominal ultrasound or no ultrasound (control) during initial ED resuscitation. The primary outcome variable was use of abdominal CT scan in patients with and without ultrasound. RESULTS Two hundred eight patients were enrolled. The mean age was 40 +/- 18 years, and 62% were men. Mechanism of injury was motor vehicle crash, 56%; automobile versus pedestrian, 18%; motorcycle crash, 16%; falls, 10%; and other, 10%. One hundred four ultrasound and 104 control patients were analyzed. There were no apparent differences between ultrasound and control groups in demographics, injury type, or Injury Severity Score. Fifty-four of 104 (52%) of the control group received abdominal CT scans versus 37 of 104 (36%) abdominal CT scans for the ultrasound group; mean difference in proportions was 15.9 (p < 0.01; 95% confidence interval, 2.6-29.1). CONCLUSION In this trial, the routine use of abdominal ultrasound in the evaluation of patients with multiple blunt injuries resulted in significantly fewer abdominal CT scans being obtained. A larger trial is needed to more clearly define the clinical and financial impact of ultrasound in the management of blunt abdominal trauma.

Abstract
The Health Insurance Portability and Accountability Act (HIPAA) is intended to simplify administrative processes and improve health information security. There are a number of traditional ways to address the expense and complexities of simplification, but none of them are bargains or beauties to behold: (1) Do-it-yourself encryption; (2) new back-end system purchases; (3) legacy system re-programming; or (4) onerous paper documentation. The good news is that 'second generation' e-health solutions are emerging that act as internal "wrappers" for health plan or provider data systems. They provide both an interface for end-users and a layer of security for organizational information and allow detailed patient-related data to remain at the system owner's physical location. These second generation solutions don't just 'connect,' data, they actually 'understand' the information, and can use data elements to invoke necessary rules, processing pathways, or personalization for specific stakeholders as required by HIPAA.

Abstract
All health care providers, plans, and clearinghouses will be affected by the federally mandated uniform standards for administrative transactions. This article presents distilled core information about the Health Insurance Portability and Accountability Act (HIPAA) legislation--the standards, penalties for violations, and status of final rules. It also raises several key unsolved issues of which clinicians, executives, and health care providers must be aware so they can prepare and plan for the upcoming changes. HIPAA is intended to improve the efficiency and effectiveness of the health care system, as well as to increase the protection and confidentiality of individually identifiable health information. The costs of making the transition to the legislated standards and processes remain a worrisome factor. Although there are two years before these standards must be implemented, and cost and compliance issues resolved, work has already begun in many health institutions to identify and address them.

Abstract
A longitudinal multigenerational design was used to examine the intergenerational transmission of smoking and the correlated transmission of parental support and control. Whether maternal socialization of adolescent smoking (both general parenting practices and smoking-specific strategies) would predict adolescent smoking both directly and indirectly by affecting peer affiliations was tested. There was strong evidence for the intergenerational transmission of cigarette smoking and for the relation between peer smoking and adolescent smoking. Both general parenting practices and smoking-specific discussion and punishment were significantly related to adolescents' smoking, especially for adolescent-reported parenting. Support for the intergenerational transmission of parenting practices emerged only in mothers' reports of support. Results suggest expanding current peer-focused prevention efforts to include parental socialization strategies.

Abstract
HIV and AIDS is a growing health risk for heterosexual women, particularly women of color (Centers for Disease Control and Prevention, 1997). Our research identified 5 types of HIV sexual risk taking in 3 independent samples of adult women from a New England Community: Group A women were noted by low to moderate levels of the 4 risk markers (i.e., unprotected vaginal sex, perceived partner-related risk, number of sexual partners, and unprotected anal sex); Group B women reported very high frequency of unprotected vaginal sex; Group C women were characterized by unprotected anal sex; Group D women had high perceived partner risk; and Group E women reported extremely high levels on all 4 HIV risk markers. Sexual risk groups were validated by demonstrating significant differences among groups on relevant behaviors, interpersonal experiences, and attitudes. Compared to other women, higher risk types reported greater behavioral risk practices (substance use, prostitution, diverse sexual experience), interpersonal risk experiences (sexual abuse, violence), initiation sexual assertiveness, and attitudinal risks (psychosocial distress). They reported less interpersonal assurance (surety of own and partner's HIV status), sexual assertiveness (for condom use and partner communication), psychosocial strengths (sexual self-acceptance), and transtheoretical readiness for change (condom use efficacy, readiness to consider condoms). Results provide additional support for the multifaceted model of HIV risk and the transtheoretical model. Suggestions for specifically focused interventions are given, depending on the pattern of sexual risk taking.

DESIGN Virologic substudies of Phase III clinical trials NV14256 and SV14604. METHODS Population sequencing of HIV protease genes amplified from pre- and post-treatment plasma. Phenotyping of peripheral blood mononuclear cell (PBMC)-derived virus isolates, and genotyping of proviral DNA clones amplified from PBMC used in the expansion of virus isolates. RESULTS In both trials the incidence of Met90 remained at < or = 20% in subjects receiving SQV in combination with ddC (with or without ZDV) for 1 year. A Val48 substitution was observed in two out of 81 subjects after 24 weeks and in two out of 75 subjects after 48 weeks. In 12 out of 13 NV14256 subjects with viral load rebound during SQV monotherapy these substitutions were associated with the rebound. In subjects treated with SQV plus ddC, rebound was associated with SQV resistance in six out of 22 cases and ddC resistance in five out of 22 cases. The incidences of non-BRU residues at positions 10, 63 and 71 were increased significantly (P < 0.05, Fisher's exact test) after SQV treatment with or without ZDV. However, comparison of genotypic and phenotypic data showed that these changes were not associated with reduced sensitivity to SQV. CONCLUSIONS Virological failure during combination therapy can be due to resistance to either treatment drug, emphasising the need to change both the reverse transcriptase inhibitor and the protease inhibitor. Only Val48 and Met90 correlated directly with the development of reduced drug sensitivity during treatment with SQV in vivo.

Abstract
The current study examined the natural history of smoking from adolescence to adulthood in a community sample. Participants were from a longitudinal study (N = 4,035, 51.7% female, average age = 29 years). Group-level analyses showed a significant increase in smoking from adolescence to young adulthood and a nonsignificant decline after the mid-20s. Individual-level analyses showed that there was appreciable cessation and relapse but little new initiation in adulthood. Both adolescent and young adult smoking status were powerful predictors of adult smoking. Moreover, there was less cessation among less educated individuals and those with smoking parents, and more cessation among those who assumed adult social roles. The findings support the importance of prevention campaigns aimed at adolescent smoking and also suggest that those with lower educational attainment or with a family history of smoking are at heightened risk.

Abstract
Establishing central intravenous access in the emergency department (ED) is often both crucial and difficult. In patients with nonexistant or ambiguous external anatomic landmarks, a real-time ultrasound guided approach to internal jugular vein cannulation is useful. In addition, the use of ultrasound guidance in internal jugular vein cannulation is supported by reports that have documented reductions in number of cannulation attempts, time required to establish central access, and rate of complications. The use of ultrasound for establishing central venous access has never been described in an ED setting. Two such cases in which ultrasound was extremely helpful for establishing central access in an ED are reported, the techniques employed for real-time ultrasound guidance of internal jugular vein catheterization are described, and the literature that supports the use of this technique is reviewed.

Abstract
The largest part of the medical record today consists of notes documenting the care delivered to patients and the clinical events relevant to diagnosis and treatment. These "progress notes" serve as the repository of medical facts and clinical thinking, and are intended as a concise vehicle of communication about a patient's condition to those who access the health record. They should be readable, easily understood, complete, accurate, and concise. They must also be flexible enough to logically convey to others what happened during an encounter, e.g., the chain of events during the visit, as well as guaranteeing full accountability for documented material, e.g., who recorded the information and when it was recorded. This paper describes a model for progress notes, which addresses the above needs, and outlines the rationale and principles which led to that model.

Abstract
This study examined prospective predictors of attempts to quit smoking and successful quitting among those who attempted to quit (n = 700), using a long-term longitudinal study of the natural history of cigarette smoking in a midwestern community sample. Participants, originally surveyed in 6th-12th grade (1980-1983), were followed up in 1987 and 1994. Results showed that amount of smoking, gender, education, health beliefs about smoking, value on healthy lifestyle, motives for smoking, reasons for quitting, and occupancy of young adult social roles were significant predictors of cessation. However, there were different predictors of attempts to quit and successful quitting among those who attempted to quit. From a public health perspective, both predictors of quit attempts and predictors of successful quitting among attempters are useful targets for intervention.

Abstract
The purpose of this study was to determine if cerebral blood flow (CBF) alterations are associated with discontinuation of heroin in chronic heroin users, and whether these alterations are reversible during abstinence. Ten physically healthy opioid-dependent males, hospitalized on an inpatient drug rehabilitation unit, were studied. Each patient had an initial single photon emission computed tomographic (SPECT) scan with the radiotracer technetium-99m-d,l-hexamethylpropyleneamine oxime (99mTc-HMPAO) 1 week after opiate discontinuation and a repeat scan 2 weeks later. The initial scans in 9 of the 10 subjects demonstrated significant, often discrete, perfusion defects, especially in the frontal, parietal, and temporal cortices. Two weeks later, repeat brain perfusion SPECT scans showed improvement in all nine subjects who had abnormal scans. Comparisons of the first scan with the second scan showed an increase in cortical uptake on the repeat SPECT study. All subjects had normal computed tomographic or magnetic resonance imaging scans. The results of this preliminary study suggest that the chronic use of opiates, like chronic use of cocaine, results in perfusion abnormalities without corresponding abnormalities on imaging studies of cerebral anatomy and morphology. This study also documents that these perfusion defects are partially reversible with short-term abstinence.

Abstract
In October 1992, lengthy new guidelines for cardiopulmonary resuscitation and emergency cardiac care were published by the Emergency Cardiac Care Committee and Subcommittees of the American Heart Association. These guidelines represent the efforts of the world's experts in emergency cardiac care. Yet they may be difficult for the busy clinician to digest in a timely fashion. In this article we summarize the changes in the guidelines from the 1986 version. It is not intended as a substitute for the original document but rather as an adjunct to help the clinician assimilate this new information.

Abstract
A gradient head coil has been developed, incorporating two independent gradients within the conventional body coil of the magnetic resonance (MR) system, with reduced rise times (200 microseconds) and maximum amplitudes of 37 and 18 mT/m in the z and y directions, respectively. This gradient coil was systematically evaluated by testing two-dimensional (2D) and three-dimensional (3D) time-of-flight (TOF) MR angiography sequences applied to a pulsatile flow phantom simulating a carotid stenosis and the intracranial vasculature. When standard 2D and 3D TOF MR angiography techniques were used to image the carotid stenosis model, dramatic signal loss in the stenotic segment and a large flow void distal to the stenosis were seen. The shorter (3.8 msec) absolute echo times (TEs) achievable with the gradient coil in 3D sequences substantially reduced the phase dispersion and associated signal loss in the region of stenosis. Shorter TEs alone (3.2 msec) did not minimize signal loss, and first-order flow compensation in the read and section-select directions provided further improvements (despite slightly longer TEs). Reduction of TEs in 2D sequences yielded relatively poor results regardless of the refocusing scheme or TE. This study confirms the predicted benefits of a dedicated coil with improved gradient capabilities for 3D MR angiography. The study suggests the limitations of 2D TOF MR angiography in the evaluation of severe stenoses.

Abstract
Previous studies have shown that beta 2 microglobulin (beta 2m) is associated with glycoproteins present on the envelope of urinary human cytomegalovirus (CMV). beta 2m is non-covalently associated with the alpha chain of human leukocyte antigen (HLA) class I antigens and therefore it was of interest to determine whether the class I alpha chain is also associated with the beta 2m-CMV complex. Using a panel of monoclonal antibodies recognizing different conformational determinants on the HLA class I heterodimer or free beta 2m, we have shown that beta 2m but not the alpha chain of HLA class I could be immunoprecipitated from 125I-surface-labelled virions purified directly from urine. We therefore conclude that host class I HLA alpha chains are not associated with beta 2m on the envelope of urinary CMV.

Abstract
The effect of human interleukin 6 (IL-6) and interleukin 1 (IL-1) on cells of the megakaryocyte lineage from murine bone marrow was examined. In bone marrow liquid culture, IL-6 but not IL-1 increases the amount of acetylcholinesterase, a megakaryocyte marker. In semisolid colony assays, a low level of interleukin 3 (IL-3) was used as a growth factor, and IL-6 and IL-1 were tested for their ability to potentiate the activity of IL-3 to stimulate megakaryocyte colony formation. IL-6 and/or IL-1 had no effect on megakaryocyte colony formation in the absence of IL-3. However, IL-6 was able to stimulate increased megakaryocyte colonies in the presence of IL-3. IL-1 was able to potentiate colony formation only in the presence of both IL-3 and IL-6.

Abstract
To determine temporal evolution of sustained ventricular arrhythmias inducible after acute myocardial infarction (AMI), serial programmed ventricular stimulation (PVS) was performed in 27 patients 15 +/- 4 and 150 +/- 28 days after AMI. These patients did not have worsening of congestive heart failure or angina, coronary artery bypass surgery or spontaneous sustained ventricular tachycardia (VT) in the period between 2 PVS studies. During initial PVS, sustained VT or ventricular fibrillation (VF) was inducible in 17 patients (group I) and was not inducible in 10 (group II). Late PVS in group I induced sustained VT or VF in 8 patients (47%) and nonsustained VT or no VT in 9 (53%). A decrease in late inducibility of sustained VT/VF was greater for arrhythmias induced during initial PVS by triple extrastimuli and burst pacing than for those induced by double extrastimuli (88% vs 25%, p less than 0.04), but appeared to be unrelated to the morphologic characteristics or cycle length of the initially induced sustained VT or VF and to other clinical, hemodynamic or angiographic variables. During late PVS in 10 group II patients, sustained VT or VF remained noninducible in 9 (90% concordance); in 1 patient sustained VT was induced. During a mean follow-up of 14 +/- 5 months since late PVS, none of 27 patients had spontaneous sustained VT and 2 patients in group I died suddenly.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We evaluated the efficacy of single oral dose combining 20 mg pindolol and 120 mg verapamil in termination of paroxysmal supraventricular tachycardia (SVT) in 12 patients with recurrent symptomatic tachycardia. All had electrically inducible SVT lasting longer than 30 minutes. Patients were administered placebo or crushed pindolol and verapamil on 2 consecutive days after tachycardia was electrically induced and allowed to sustain for 30 minutes. With placebo, SVT lasted 186 +/- 18 minutes (mean +/- SEM); five patients converted spontaneously within 121 to 180 minutes. With pindolol and verapamil, 9 of 12 patients (responders) converted to sinus rhythm within 8 to 74 minutes. The mean duration of SVT in the nine responders was 28 +/- 8 minutes compared with 168 +/- 20 minutes on placebo (p less than 0.001). Before termination, tachycardia rate on pindolol and verapamil slowed significantly from 182 +/- 5 to 164 +/- 7/min (p less than 0.05) compared with no significant change in the rate of SVT on placebo. The mean systolic blood pressure during tachycardia was 97 +/- 5 mm Hg with placebo and 101 +/- 7 mm Hg with pindolol and verapamil. Serum levels of pindolol and verapamil obtained in seven patients at time of spontaneous termination of tachycardia were 66 +/- 13 and 56 +/- 14 ng/ml, respectively. The side effects with pindolol and verapamil included lightheadedness in one patient and symptoms of rapid palpitations in three. A single oral dose of pindolol and verapamil is safe and effective in termination of acute paroxysmal SVT and may be the initial therapy of choice in selected patients.

Abstract
Hypercalcemia, often associated with certain types of adult tumors, has also been described in pediatric neoplasms. In childhood, the more common associations include lymphoma, leukemia, rhabdomyosarcoma and rarely neuroblastoma. However, recently, several infants with hypercalcemia were described having renal tumors without bone metastases. The following is a case report of a 2-month-old infant who presented with severe hypercalcemia and a large right-sided abdominal mass, which at surgery was diagnosed as a cellular mesoblastic nephroma.

Abstract
Electrophysiologic study, 24-hour ambulatory electrocardiographic monitoring, treadmill exercise test and angiographic evaluations were performed in 45 patients 14 +/- 3 days (mean +/- standard deviation) after acute myocardial infarction. Electrophysiologic study protocol included burst ventricular pacing and 1 to 3 ventricular extrastimuli at 2 cycle lengths from right ventricular apex, right ventricular outflow and left ventricle. Sustained monomorphic ventricular tachycardia (VT) (13 patients) or ventricular fibrillation (VF) (7 patients) was induced in 20 patients (44%) (group I). In these 20 patients, VT/VF was inducible with 2 extrastimuli in 10 patients, 3 extrastimuli in 9 patients and burst pacing in 1 patient. In the remaining 25 patients (56%), induction of no fewer than 7 ventricular beats were noted (group II). Severe left ventricular (LV) wall motion abnormalities occurred in 70% of group I patients and 22% of group II patients (p less than 0.005). There was no difference in the site of infarction, frequency and grade of ventricular ectopic rhythm on ambulatory electrocardiographic monitoring, double product on submaximal exercise, LV ejection fraction, and number of obstructed coronary arteries (70% or greater) (p greater than 0.1) between group I and group II patients. During a mean follow-up of 10 +/- 3 months, 1 patient in each group died suddenly, and in 1 group I patient spontaneous sustained VT developed which was identical in morphologic configuration to that induced during electrophysiologic study. In conclusion, electrical induction of sustained VT or VF during electrophysiologic study is common in patients 2 weeks after acute myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In three patients with pulmonary embolism, two-dimensional echocardiography demonstrated thrombi within the right heart chambers. These thrombi, suspected of embolizing into the pulmonary circulation, showed varied morphology and mobility. Of the two patients undergoing embolectomy, only one survived. The third patient improved with anticoagulation therapy. Two-dimensional echocardiography is useful in evaluating patients suspected of having pulmonary thromboembolism because it may demonstrate evolution of the thrombus.

Abstract
The value of a previously validated portable, continuous-wave Doppler computer was assessed for measuring changes in cardiac output (CO). Simultaneous thermodilution and Doppler CO values were measured in triplicate in 16 patients undergoing clinical intervention with vasodilator therapy. A continuous-wave Doppler transducer was placed in the suprasternal notch and directed toward the ascending aorta and angled until the maximal velocity signal was obtained. The correlation coefficient was 0.92 (standard error of the estimate [SEE] = 0.48 liter/min) at rest; with intervention it was 0.88 (SEE = 0.52 liter/min). Our data indicate that the Doppler computer technique, when used in selected patients, is reliable in detecting changes in CO after vasodilator therapy. It may be of value in clinical situations in which hemodynamic monitoring is impractical.

During the past two years five patients with malignant primary bone tumors undergoing amputation or resection of the involved bone had preoperative computed tomography (CT) examination of the medullary cavity. The contralateral extremity was used as a control in all cases. The positive attenuation coefficient of the marrow indicated the extent of tumor infiltration. The correlation between the preoperative CT and pathologic measurement ranged between 1-8 mm, an accuracy greater than 94%.

Abstract
Extraosseous Ewing sarcoma--a rare clinical entity--is described and the radiographic and histologic features discussed. Histologically this type of tumor may be differentiated from other soft tissue malignancies, but the ultrastructural glycogen content of the cytoplasm makes it frequently inseparable from the conventional osseous form of Ewing sarcoma. In spite of the presence of a huge paraosseal mass with bone erosion or periosteal new bone, computed tomography was the only preoperative modality able to provide evidence of non-involvement of the marrow cavity. However, histologic documentation is necessary to prove that one is dealing with a totally extraosseous Ewing sarcoma.

At thoracotomy each patient had a cystic mass containing a brownish, turbid, mucoid material. The pathologic diagnosis in each case was a bronchogenic cyst. The possibility of such a cyst should not be excluded because of a high CT number, which reflects the turbid contents of the cyst.
