Incidental findings in CT colonography: literature review and survey of current research practice

Incidental findings (IFs) of potential medical significance are seen in approximately 5-8 percent of asymptomatic subjects and 16 percent of symptomatic subjects participating in large computed tomography (CT) colonography (CTC) studies, with the incidence varying further by CT acquisition technique. While most CTC research programs have a well-defined plan to detect and disclose IFs, such plans are largely communicated only verbally. Written consent documents should also inform subjects of how IFs of potential medical significance will be detected and reported in CTC research studies.     

Community crime prevention: A review and synthesis of the literature

In the absence of effective formal means for controlling crime in the Western world, community crime prevention has emerged as a major alternative and supplement to the criminal justice system. This article attempts to review what is known currently about the nature, extent, and effectiveness of community-based efforts to prevent residential crime. Included in this assessment are citizen actions to protect themselves, their property, and their neighborhood, as well as efforts to prevent crime through changes in the physical environmental and through innovations in community policing. The historical, theoretical, and empirical rationale for community crime prevention strategies are discussed, but primary attention is given to the results of evaluation research in the field. Although community-based efforts are supported widely by theory, studies of natural covariation, and by numerous poorly designed evaluations, there is a paucity of strong demonstrations and evaluations showing that such interventions can alter the behavior and local environments of persons who are not already predisposed to crime prevention. Substantially more research is needed to determine the collective benefits of community crime prevention strategies, but a number of promising approaches currently are being developed.     

Organization structure as a factor in innovation: A review of the literature

There are several approaches to the organization of an activity. Some of the better known methods are by function, project or a matrix. Each of these methods is investigated in terms of its effect on innovation. Some of the advantages and disadvantages of each are discussed. All discussion is carefully supported by reference to current literature.

International sex offender registration laws: research and evaluation issues based on a review of current scientific literature

In many jurisdictions, anyone convicted of a sexual offense is required to register with police, often for life. Nine different countries have now implemented sex offender registries in an attempt to protect the public from the perceived threat posed by sexual offenders. Yet such laws have been criticized as being overly inclusive, tying up limited law enforcement resources to track many offenders who pose little risk of sexual reoffending. This paper considers the available research evidence relevant to the effectiveness of such laws for the deterrence of sexual offending and the investigation of sex crimes. It is concluded that significant gaps persist in our knowledge of whether existing laws effectively reduce sexual offending or reoffending and that large-scale, well-designed studies of the impact of sex offender registration on rates of offending, the collateral consequences to offenders and their families, and the costs of such laws are needed.     

Thy brother's keeper: A review of the literature on correctional officers

Individualized offender risk models do not account for expected reductions in risk that are caused by programmatic interventions, in part because of a presumption of program ineffectiveness. We examined two relatively unevaluated types of correctional programs—community-based prison release programs and prison furloughs—for adult males in the Massachusetts Department of Correction to determine whether there was an identifiable intervention effect on recidivism rates. We studied three samples of male inmates who were released during the 1970s, using base expectancy methodology to control for their background characteristics. We also examined 11-year trends in recidivism, comparing program participants to nonparticipants. Furlough participation, both alone and followed by prerelease, appears to have a pronounced and consistent positive impact on lowered recidivism. Implications for reintegration theory, risk assessment policy, and research are discussed.     

Joinder of criminal offenses: A review of the legal and psychological literature

Criminal courts routinely allow a defendant to be tried for multiple charges in a single trial. The practice is known as joinder of offenses. The issue of joinder of offenses is examined from a legal and psychological perspective. Relevant court decisions and their implications are discussed. In addition, the recent research conducted by social scientists concerning the possible reasons for the prejudicial effects of joinder of offenses is critically reviewed. Suggestions are offered, based upon previous joinder research, for the direction of future research into the loci of the effect and into potential remedies.This paper is an elaboration of one presented at the annual meeting of the Academy of Criminal Justice Sciences, Chicago, March 1984.     

Wife assault theory,research, and treatment: A literature review

Treatments for wife assaulters and their victims have been based on a variety of psychological and sociological theories. Tests of theory based on investigation of assailant and victim characteristics as well as evaluation of treatment effects based on empirical outcome studies have yielded diverse results. In reviewing the literature it appears that development of assailant typologies based on extent of psychopathology, severity of violence, and context of violence has potential utility in guiding future treatment decisions for assaulters. Further development of similar typologies for classifying responses of assaulted women could yield similar results. Population screening and matching programs to individual characteristics could be expected to improve clinical outcomes.     

A case of Ludwig angina: a case report and review of the literature

Ludwig angina is a rapidly progressing submaxillary, submandibular, and sublingual necrotizing cellulitis of the floor of the mouth that can have lethal consequences due to airway obstruction. Various aerobic and anaerobic microorganisms, and less often fungi, have been implicated to cause Ludwig angina, including oral flora such as streptococci and staphylococci. Early recognition and the use of parenteral antibiotics can prevent mortality and morbidity. We report a case of a 25-year-old white man who was admitted to the hospital by his dentist after being diagnosed with Ludwig angina secondary to periodontal abscesses involving teeth #17 and #32. Although antibiotics were administered, while in the hospital, the decedent had difficulty swallowing and was drooling. He suddenly began to have seizure-like activity thought to be anoxic myoclonus. The decedent was aggressively resuscitated and taken to the operating room for neck exploration and a tracheostomy. Neck exploration revealed severe necrotizing acute inflammation of the deep soft tissues and musculature of the neck. He remained on life support for 7 days until he was declared brain dead. Ludwig angina is a progressive cellulitis that often results in death by asphyxia. Ludwig angina can be complicated by subsequent deep neck infection. The underlying etiologies and common scenarios are examined, and significant autopsy findings and dissecting procedures are discussed. The pathophysiology of Ludwig angina is studied with a review of the current literature.     

To stay or quit: A review of the literature on correctional staff turnover

Correctional staff are the most important asset for any correctional agency. In fact, they are the heart and soul of any correctional organization. Many staff, however, voluntarily quit. The cost of this turnover is high for correctional organizations. Nonetheless, correctional staff turnover has generated only limited research. Moreover, there has been little direction in the correctional turn-over research. The different forms of turnover are discussed and the correctional staff turnover research is reviewed. A causal model for correctional staff voluntary turnover is developed and presented to guide future research. This article is a revision of a paper presented at the 1998 American Society of Criminology Annual meeting in Washington D. C. and my dissertation. The author would like to thank the anonymous reviewers for their comments and suggestions, as well as Janet Lambert, Ferris State University, for her assistance in editing and proofreading this article.     

Identifying risk factors in stalking: a review of current research

Stalking is a behaviour which can cause substantial damage to its victims, whether the perpetrator is violent or not. Victims face a range of risks including not only assault, but persistent or recurrent stalking and varying degrees of psychological and social damage. The responsibility for assessing and managing these risks often falls to the mental health professional, yet the emerging stalking risk assessment literature is at too early a stage to provide clinicians with empirically derived evidence upon which to base their clinical practice. This paper reviews existing research to identify those factors currently believed to be associated with increased risk of physical and sexual assault; with persistent and/or recurrent stalking; and, with psychological and social damage.     

University technology transfer in China: a literature review and taxonomy

The Chinese university system is one of the world’s largest academic research performers and technology transfer is one of the system’s central roles. Academic interest in Chinese university technology transfer in both the West and China has increased in parallel. This review aims to outline what is known and evaluate the state of research about university technology transfer in China. To be comprehensive, uniquely this review considers the relevant journal articles in both English and Chinese languages. The major themes and methodologies used by authors are identified. The evolution of the literature, particularly those in Chinese from general discussions often with minimal citations to more empirically rigorous studies is documented. It is also shown that the English and Chinese language literatures have little overlap in terms of citations, thereby indicating that the two research communities are still largely disconnected. It is found that the sources of data have remained quite limited and the quantitative research is based almost entirely upon government statistics collected for administrative purpose. The concluding discussion suggests possible avenues for future progress in terms of developing new data sources and increasing the cross-fertilization of two research communities.     

Asian gangs in the United States: The current state of the research literature

Since the late 1980s, criminologists have been interestedin analyzing Asian gangs. Despite the rather sharp increasein books and articles published on the subject in the1990s, there appears to exist no consensus on the nature and etiologyof Asian gangs. This paper describes the current state ofresearch on Asian gangs and assesses whether or not thereis a dominant criminological theory on their cause. Itcompares and contrasts African American and Asian gangs,and closes with research and policy recommendations.     

Infanticide in Malaysia: two case reports and a review of literature

In a strict and conservative society like Malaysia, the number of cases of infanticide has continued to occur. The authors present two typical cases of infanticide in Malaysia. Case 1 concerned a body of a fully mature newborn fetus disposed in a rubbish bin. The head was traumatically amputated by the rubbish truck's compactor. The umbilical cord was still attached to the body, with no reddening around the insertion. The severed neck showed features consistent with post-mortem amputation. The significant finding was expanded crepitant lungs, which floated in water. The histology of the lungs showed expanded alveoli. It was concluded that the baby had been born alive, but no cause of death could be elicited. Case 2 concerned a decomposed mature newborn found in a scrub forest. The internal organs showed advanced putrefaction, the lungs being collapsed, congested, and hemorrhagic, typical of decomposed lungs. No conclusion could be made about the state of birth or the cause of death because of the putrefied state of the body. The two cases illustrate the typical cases and problems faced by pathologists locally and probably elsewhere in the world. Most of the bodies are found in a putrefied state. Pathologists have to ascertain not only maturity and live birth but also the cause of death, which may be very subtle or masked by putrefaction. The problems of diagnosis of live birth are discussed.     

Policing in the People's Republic of China: a review of recent literature

Recent literature on policing in the People's Republic of China, though very limited, has encompassed a wide range of topics including police organizations, roles and functions, subculture, policing strategies (such as community policing, campaign style policing, and the comprehensive management approach), and a number of issues and problems (such as abuse of power, accountability, and police citizen relations). These studies serve to establish a foundation for a better understanding of the complex social control in China. The present study summarizes the findings of recent research, identifies its limitations, and discusses the directions and challenges in future research.

Thiamylal: review of the literature and report of a suicide

A 28-year-old white male medical student was found hanging by the neck from the bathroom closet of a hotel room. An intravenous infusion line leading from a bottle of thiamylal sodium (an ultrashort-acting barbiturate) was inserted into the antecubital vein of the left arm. Blood was analyzed for alcohol and other volatiles and for acidic, basic, and neutral drugs. Only thiamylal was detected. Thiamylal was quantified by high-performance liquid chromatography with ultraviolet detection, and its presence was confirmed by gas chromatography/mass spectrometry. The tissue distribution of thiamylal was 29 mg/L in blood, 1.4 mg/L in urine, 16 mg/L in bile, 135 mg/kg in liver, 25 mg/kg in kidney, and 0.4 mg in the stomach contents. The uptake and distribution of thiamylal is similar to thiopental. The distribution of the drug in this case was compared to that of other fatalities involving ultrashort-acting barbiturates.     

Suicide by xylene ingestion. A case report and review of literature

A 27-year-old male committed suicide by ingestion of a large quantity of xylene. The presence of xylene in the tissues of the victim was confirmed by chromatographic and spectrometric techniques. High levels of xylene were detected in blood (11 mg/dl), gastric contents (880 mg/dl), and duodenal contents (3,300 mg/dl). Histological examination of the lungs showed severe congestion and acute pulmonary edema. Review of the relevant literature is presented.     

Pathologic findings in malignant hyperthermia: a case report and review of literature

Malignant hyperthermia (MH) is a rare, potentially lethal disorder of skeletal muscle calcium homeostasis characterized by muscle contracture and life-threatening hypermetabolic crisis following exposure to halogenated anesthetics and depolarizing muscle relaxants. Susceptibility to MH results from mutations in calcium channel proteins that mediate excitation-contraction coupling, with the ryanodine receptor calcium release channel (RyR1) representing the major locus. The mode of inheritance appears to be autosomal dominant with variable penetrance. The authors report the death of a 60-year-old white male with a history of low back pain. He had undergone 2 back surgeries previously, the first occurring 10 years prior to his current presentation. Both previous procedures were done under generalized anesthetic with no complications. Recently, he developed stenosis and presented for fusion of vertebrae L3 and L4. The procedure was performed under general anesthetic including sevoflurane, with no intraoperative complications. The anesthesiologist noted that, near the end of the 2-hour procedure, the decedent's CO2 levels were slightly elevated. After the procedure, the decedent was extubated, the temperature probe which had been recording normal values was removed, and he was rolled from ventral to dorsal position. He immediately became hypotensive and bradycardic. Lifesaving interventions were begun. Subsequently, he went into cardiac arrest, at which time the temperature probe was reinserted into the trachea, where it read a body temperature of 109 degrees F. Malignant hyperthermia protocol was initiated, and interventions continued for over 2 hours, at which time they failed. At autopsy, the abdomen contained 1800 mL of blood, and bilateral hematomas were present in the psoas muscles. The authors present this case of clinically apparent malignant hyperthermia, discuss how to approach such a case, the gross and microscopic findings, ancillary studies, and a review of the literature.     

Stud guns revisited: report of a suicide and literature review

Stud guns (powder-actuated fastening tools) are a commonly used construction tool. Accidental injuries and fatalities are no longer frequent, presumably because of current safety features and practices. A case of an intentional fatal wound (suicide) is described. A literature review of stud gun injuries is also presented.
