Applications of RAPD technology to questions of paternity and maternity in studies of insect reproductive traits are discussed. We present three case studies where RAPD fingerprinting reveals levels of complexity in insect systems that help us to understand the causal mechanisms underlying observed behaviour. Finally, we consider ways in which ...

A case-referent study was carried out among meatcutters, sausage markers, and packers in a large meat-processing plant to investigate the association between psychomotor capacity and occurrence of tenosynovitis. Reaction time, movement time, manual dexterity, visual attention and visuospatial ability were measured in 26 cases with a history of two or ...

A retrospective study was conducted of 103 balance-disturbed patients of mixed etiologies tested with electronystagmography (ENG) and computerized dynamic posturography (CDP). CDP was abnormal for 83% of the group as compared to 42% abnormal ENG results. In cases of otolithic dysfunction, ENG was more sensitive and gave specific information. Results ...

Next to oxygen and silicon, aluminum is the most common element on this planet's surface. Studies of potential carcinogenics in aluminum workers have been reported to be equivocal, and consequently can give rise to serious global concern. However, studies have not taken into consideration smoking histories. Also a review of ...

This paper reviews the available evidence concerning the atherogenic potential of carbon monoxide. The evidence comes from two different types of studies--epidemiology studies on populations of humans chronically exposed to carbon monoxide, and animal studies conducted under conditions of controlled exposure to carbon monoxide. Data from both epidemiology and animal ...

Clinicians continue to focus attention on the sacroiliac joint (SIJ) as one cause of low back pain. Considerable literature now exists to support the contention that symptoms arise from the sacroiliac region. In the last couple of decades, studies with quantitative data, often using sophisticated methods, have added to our ...

A well-written case study has an important place in nursing literature because it describes new problems and techniques in clinical practice and helps identify researchable clinical questions. Do not be deceived into thinking that the case study manuscript is easy to write, because it is not. But, with the application ...

Observer and self-reports of abstinence from smoking were compared at 2-, 7-, 14-, 30-, 90-, and 180-day follow-ups and with biochemical verification at 180-day follow-up in a study of 630 self-quitters. Observer reports were often not returned (25-65%), rarely refuted self-reported abstinence (< 1%), and were often discordant with biochemical ...

Exencephaly as a precursor of anencephaly is well delineated in animal studies. In humans, a similar though unproven embryologic sequence is postulated. In the case reported, serial ultrasound studies allowed us to identify a 16-week human exencephalic fetus and observe the cephalic changes during its progression to a classic anencephalic ...

Investigations of confidentiality management have been constrained by an inability to obtain direct measures of clinicians' behaviors when deciding whether to breach or safeguard a confidence. Some researchers have used responses to hypothetical case vignettes to derive approximations of how clinicians manage confidences entrusted to them by their patients. However, ...

Two cases of severe dystonia and dyskinesia were treated with talipexole, a dopamine autoreceptor agonist, and the metabolites of dopamine, norepinephrine, and serotonin in cerebrospinal fluid (CSF) were determined. Despite significant reductions in these metabolites in CSF, behavioral amelioration of these cases could not be observed. The present findings argue ...

Ethmoidectomy is an operation that has engendered controversy concerning the best route of surgical access. The purpose of this study was to present the results of the authors' experience in more than 1300 intranasal sphenoethmoidectomies and transantral sphenoethmoidectomies performed over a 20-year period. The authors contend that the most effective ...

The modern sociological literature on disasters highlights the fact that many of the ideas about human behaviour in disasters which were long considered as valid, are wrong. The main discovery is based on the fact that situations of crisis increase people's moral principles and capability of response. This paper illustrates ...

The Framingham Type A Scale (FTAS) is one of three primary measures of Type A behavior. Unlike the structured interview (SI) and Jenkins Activity Survey (JAS), the FTAS is correlated with neuroticism. Further, neuroticism and FTAS scores predict angina-like chest pain complaints but not more definitive coronary heart disease (CHD) ...

Berkson's bias reflects a statistical phenomenon in which differential hospitalization rates create an exposure distribution among hospitalized cases that differs from that among other cases. Importantly, previous work on Berkson's bias has not explicitly addressed the possibility of excluding prevalent or previously diagnosed cases--exclusions that are key features of many ...

A single-chamber pressure probe for rectal electromanometry was developed which seems to be superior to the complicated multichamber systems not only for clinical but also for experimental purposes. Measurements of rectoanal reflex were carried out in 268 cases with abnormal bowel function, in 103 cases following operation for Hirschsprung's disease, ...
