Physical examinations, subject

Assessment involves collecting objective and subjective data. Objective data are facts obtained by means of a physical assessment or physical examination. Subjective data are facts supplied by the patient or the patient s family. 

There are two principal chemical concepts we will cover that are important for studying the natural environment. The first is thermodynamics, which describes whether a system is at equilibrium or if it can spontaneously change by undergoing chemical reaction. We review the main first principles and extend the discussion to electrochemistry. The second main concept is how fast chemical reactions take place if they start. This study of the rate of chemical change is called chemical kinetics. We examine selected natural systems in which the rate of change helps determine the state of the system. Finally, we briefly go over some natural examples where both thermodynamic and kinetic factors are important. This brief chapter cannot provide the depth of treatment found in a textbook fully devoted to these physical chemical subjects. Those who wish a more detailed discussion of these concepts might turn to one of the following texts Atkins (1994), Levine (1995), Alberty and Silbey (1997). 

The success of therapy is measured by the degree to which the care plan decreases the pretreatment deterioration rate, preserves the patients functioning, and treats psychiatric and behavioral symptoms. The primary outcome measure is thus subjective information from the patient and the caregiver, although the MMSE can be a helpful tool for monitoring changes in the severity of illness. There are no physical examination or laboratory parameters that are used to evaluate the success of therapy.

There are several approaches and methods to conducting a nutrition assessment, but one approach that has been validated is the Subjective Global Assessment (SGA).1 Application of the SGA requires gathering the data just listed and assessing these parameters (i.e., weight change, change in diet, GI symptoms, functional capacity, and physical examination)... 

In the same opinion the Court remarked, Schoolchildren are routinely required to submit to physical examinations and vaccinations against disease... Securing order in the school environment sometimes requires that students be subjected to greater controls than those appropriate for adults. ... 

Few cases of intoxication due to occupational exposure have been reported, and, of these, two cases of pneumonitis in insecticide sprayers are of dubious validity. In one acute study, 25 volunteers were exposed to 500mg/m for 30 minutes for 10 days. After a 3-week respite, the exposure was repeated for 3 days. Each subject was thought to have absorbed Img/kg/day. Physical examination and blood and urine tests revealed no toxic manifestations.

Physical examination of the combined group of Michigan residents revealed alopecia in 4% of the subjects compared to no occurrence of alopecia in the control group. 

Gastrointestinal Effects. Earlier studies of individuals with exposure to substances contaminated with 2,3,7,8-TCDD found significant elevations in self-reported ulcers (Bond et al. 1983 Suskind and Hertzberg 1984), but a study of Vietnam veterans (USAF 1991) failed to find such effects. A more recent study evaluated the gastrointestinal effects of exposure to substances contaminated with 2,3,7,8-TCDD in an occupational cohort (Calvert et al. 1992). More than 15 years earlier, the workers were employed in the manufacture of trichlorophenol and its derivatives at 2 chemical plants. A total of 281 workers participated in the medical study the control group consisted of 260 unexposed subjects who lived in the same communities as the workers. The participants underwent a comprehensive physical examination of the abdomen and rectum. The mean serum 2,3,7,8-TCDD level (on a lipid basis) for the workers was 220 ppt and was found to be highly correlated with years of exposure to 2,3,7,8-TCDD-contaminated substances controls had a mean serum 2,3,7,8-TCDD concentration of 7 ppt. At the time of examination, the workers were not found to be at increased risk for any gastrointestinal diseases. Moreover, neither... 

During human pharmacology studies, subjects are given extensive physical examinations before the administration of the drug, after its administration, and, in the case of longer term studies, at various intervals throughout the treatment. An extensive battery of typical tests includes ... 

Dyspnea, cough, and wheezing were reported in two cases in which the subjects inhaled "massive amounts" of chromium(VI) trioxide. Marked hyperemia of the nasal mucosa without nasal septum perforation was found in both subjects upon physical examination (Meyers 1950). In a chrome plating plant where poor exhaust resulted in excessively high concentrations of chromium trioxide fumes,... 

Ocular Effects. Effects on the eyes due to direct contact of the eyes with airborne mists, dusts, or aerosols or chromium compounds are described in Section 2.2.3.2. An extensive epidemiological survey was conducted of housewives who lived in an area of Tokyo, Japan, in which contamination from chromium slag at a construction site was discovered in 1973. The housewives included in the study were those who lived in the area from 1978 to 1988, and controls included housewives who lived in uncontaminated areas. Questionnaires, physical examinations, and clinical tests were conducted annually. Higher incidences of subjective complaints of eye irritation were reported by the exposed population than the control population in the early years of the survey, but in later years the difference between the two groups became progressively less (Greater Tokyo Bureau of Hygiene 1989). 

Almost all the books compiled in this appendix can be considered computational chemistry even though some of their titles seem otherwise. The partitioning of these books into the aforementioned categories is subjective on our part and may well be better divided other ways. We physically examined less than a quarter of the books listed in the tables. Thus, for many books, we had to make a judgment based on solely the title and/or the author(s) whether the book really is about computational chemistry. 

The phase 1 clinical trial for HGB-30 consisted of 18 seronegative healthy volunteers (6/group) who were administered 10,20, or 50 pg of the vaccine at 0,6, and 14 weeks. Physical examinations and blood analyses were performed, and all subjects were followed for 1 year. Initial results indicated that the vaccine was not associated with any adverse effects. Similarly to that observed in mice and chimpanzees, antibodies to HGP-30 were observed in volunteers. Since T cell proliferative responses are considered to be optimal with fresh cells, extensive studies were carried out on one volunteer s peripheral blood lymphocytes. Increased T cell proliferation was observed. The T cell proliferation was maximal 6 weeks after the third immunization but then declined at 6 months after the third immunization. 

Healthy male subjects, aged 18-45 years (inclusive), with a Body Mass Index between 18 and 27 kg/m2 (inclusive), normal or clinically irrelevant abnormal findings (in the opinion of the investigator) in the medical history and physical examination, laboratory values, ECG, blood pressure and pulse rate, negative serology (HIV antibody, hepatitis B surface antigen, hepatitis C antibody) and urine screen for drugs of abuse. 

Prior to study entry, the subjects undergo a battery of prestudy parameters as dictated by the protocol. These parameters may include, but are not limited to, medical history, physical examination including vital signs, clinical laboratory tests, and electrocardiogram. 

The first pair of two subjects (Patient 1, Patient 2) were 57 and 55-year-old white men, respectively. Patient 1 had degenerative osteoarthritis and allergic rhinitis. Results of physical examination, routine blood tests, and zinc concentration of plasma erythrocytes and hair were within normal limits before the study. Patient 2 was diagnosed as having mild diabetes mellltus and mild hypertension. At the time the patients entered the study, there were no abnormal physical findings, and zinc status was within normal limits. 

Based on a targeted and exact anamnesis, subjective complaints by the patient and careful physical examination (s. tab. 12.5), it is possible in most cases to make a clear distinction between four different categories of jaundice (1.) haematological, (2.) hepatocellular, (J.) biliary obstructive, and (4.) hereditary, (s. tabs. 12.1,12.2,12.4)...
