In the last five years, much information has been gathered about the efficacy of several technics for managing obesity. Hospitalization with fasting, surgery, drugs, weight reducing clubs, and behavior modification methods have proven efficacious for select groups of obese individuals. Methods of behavior modification appear to offer some of the most promising management technics, since results are good, and cost and discomfort to the patient are minimal.

A survey of knowledge and nursing practice in relation to sub-mammary skin problems was conducted among ward sisters and primary nurses in one district health authority. Respondents identified a number of characteristics as predisposing factors, with obesity and poor hygiene being mentioned most frequently. A very wide selection of nursing interventions was recommended, with nurses who mentioned pharmacologically active topical preparations reporting a significantly greater number of recurrences among patients than those who relied on less sophisticated regimes. Nurses expressed a variety of opinions about the effect that this condition has on patients, ranging from no effect at all to pain and discomfort. These findings highlight the lack of a coherent strategy for treating this problem and support the continuation of a research programme examining sub-mammary skin problems and the nursing response to them.

Laparoscopy was carried out using a simplified open method on 585 patients. In the group, 173 (29.5%) had undergone a previous laparoscopy or laparotomy, 28 (4.8%) suffered from gross obesity and 1 patient had a large umbilical hernia. Laparoscopy was diagnostic in 216 (37%) patients and operative in 369 (63%). In this series there were no technical failures or major complications; the incidence of minor complications was 2.7%. The above results seem to suggest that open laparoscopy compared to the closed method may offer the advantage of a lack of contraindications secondary to previous surgery, no risk of failure with unintended laparotomy and, possibly, decreased postoperative discomfort. A larger, randomized series to settle the controversy between closed and open laparoscopy regarding the safety differences between the two approaches may result in more widespread use of the open technique.

Although microdialysis has been available for almost two decades, it has only recently been applied in investigations of adipose tissue. The microdialysis technique enables continuous sampling of metabolites and other small molecules from the extracellular space of subcutaneous adipose tissue from intact animals or man, and the exposure of this compartment locally to metabolically active agents without causing generalized effects. To date, the method has been used to measure the steady-state interstitial levels of metabolites and to investigate the regulation of lipolysis and carbohydrate metabolism in situ in subcutaneous adipose tissue. Apart from a great potential for experimental research, the microdialysis method offers several new possibilities for clinical investigation. Because microdialysis probes are easy to implant and cause little discomfort, they may be used for continuous monitoring of glucose and glycerol (lipolysis index) in the treatment of diabetes, obesity and other disorders characterized by disturbances in lipid and carbohydrate metabolism.

It is now recognized that dietary carbohydrate components influence the prevalence and severity of common degenerative diseases such as dental problems, diabetes, heart disease and obesity. Fructose and sucrose have been evaluated and compared to glucose using glucose tolerance tests, but few such comparisons have been performed for a "natural" sugar source such as honey. In this study, 33 upper trimester chiropractic students volunteered for oral glucose tolerance testing comparing sucrose, fructose and honey during successive weeks. A 75-gm carbohydrate load in 250 ml of water was ingested and blood sugar readings were taken at 0, 30, 60, 90, 120 and 240 minutes. Fructose showed minimal changes in blood sugar levels, consistent with other studies. Sucrose gave higher blood sugar readings than honey at every measurement, producing significantly (p less than .05) greater glucose intolerance. Honey provided the fewest subjective symptoms of discomfort. Given that honey has a gentler effect on blood sugar levels on a per gram basis, and tastes sweeter than sucrose so that fewer grams would be consumed, it would seem prudent to recommend honey over sucrose.

When patients present with suspected prosthetic valve dysfunction, investigation is usually instituted to delineate the site and cause thereof. Precordial cross-sectional echocardiography is often helpful in this respect, but in the patient with acute pulmonary edema, imaging may be impaired because of discomfort and respiratory distress. The information obtained may also be suboptimal as a result of concomitant obesity, chest wall deformity, and pulmonary disease. In addition, further difficulties may relate to the acoustic shadowing produced by the metallic portion of the valve and its sewing ring, especially with valves in the mitral position. In such patients, cardiac catheterization may cause further decompensation and is associated with a recognized increase in morbidity and mortality. Angiography does not accurately site regurgitant jets in relation to the prosthetic valve concerned and will not detect the presence of vegetations. Transesophageal echocardiography circumvents many of these imaging difficulties and we evaluated its use in five patients with prosthetic heart valves who presented acutely ill, in severe pulmonary edema and suspected prosthetic heart valve failure. In each case, the diagnosis of valve dysfunction was established, and precise information regarding the site and cause of the failure was obtained. No complications or deterioration in patient condition resulted from the procedure and the findings were confirmed at surgery performed within 24 hours in all five patients. Transesophageal echocardiography should be included in the assessment of acute prosthetic heart valve failure.

The purpose of this study was to compare the effect of the Z-track intramuscular injection technique with the effect of the stand and intramuscular injection technique on the severity of discomfort and lesions at the injection site. The subjects of the study were 20 patients with only early tuberculosis excluding another abnormalities (a skin rash, allergy to topical use of alcohol, jaundice, edema, neurosensory abnormality, coagulation defects, obesity and thin). Data collection was done from Feb. 1 to March 15, 1988 by means of Korean Pain Measurement Tool, Visual Analogue Scale, and Objective measures of injection site lesions. The results of this study were as follows: 1) Hypothesis 1; "The severity of subject discomfort is less following administration of the Z-track intramuscular injection technique than following administration injection technique." was not supported. 2) Hypothesis 2; "The degrees of severity subject discomfort is less following administration of the Z-track intramuscular injection technique than following administration of the standard intramuscular injection technique." was not supported. 3) Hypothesis 3; "The severity of injection sites lesions is less following administration of the Z-track intramuscular injection technique than following administration of the standard intramuscular injection techniques." was not supported. 4) The terms that were selected included factor II (mild-moderate pain) of Ratio Scale Measuring Pain using Korean Pain Terms. In conclusion; it was found that there was not a difference from the severity of subject discomfort between two groups, but the degrees of severity of subject discomfort about following administration of the Z-track intramuscular injection was tended to be declined. Therefore further studies suggest that the Z-track intramuscular injection technique can decrease the severity of discomfort in persons receiving frequently intramuscular injections. First of all, it is necessary to be developed an effect tool of dis comfort measurement for the intramuscular injection in Korean.

Two studies were performed in the same subjects to explore the relationship between stomach capacity and food intake. In the first study, a balloon was passed orally into the stomach of four lean and four obese subjects before they ingested a liquid lunch meal. The balloon was filled with 0, 200, 400, 600, and 800 ml of water in a random sequence on different days. The balloon was kept inflated during ingestion then deflated and removed. Food intake was significantly reduced (p less than 0.01) by a balloon volume of greater than or equal to 400 ml. In the second study, another balloon was inserted into the stomach of these subjects to estimate stomach capacity. The balloon was gradually filled at the rate of 100 ml/min with 30 sec pauses. The subjects rated their discomfort as 1 to 10, from no discomfort to extreme discomfort. A rating of 10 was the main index for stomach capacity. Mean capacity (ml) for the lean subjects was 1100 +/- 185 (SE) and for the obese 1925 +/- 175 (SE), t = 3.24, p less than 0.02. When stomach capacity from the second study was correlated to spontaneous food intake at 0 balloon volume from the first study, r = .44, n.s. However, the relationship between stomach capacity and the balloon volume needed to suppress 50% of spontaneous intake was significant, r = .66, p less than 0.05. This may have implications for treatment of obesity with a gastric balloon.

Obesity is assumed to be a risk factor in the occurrence of thrombophlebitis. We studied 168 consecutive patients retrospectively; 33 were men and 135 women, with an average age of 34 (range 27 to 41) years. All patients had a gastric bypass because of obesity, with a minimum of 100 lb over normal weight. The mean weight was 279.2 lb (range 191 to 500). Only three patients had a history of deep vein thrombophlebitis, with no thromboembolism. Eighty-four of the patients were studied preoperatively by noninvasive means (Doppler, impedance plethysmography [IPG], phleborheography [PRG]); 12 had evidence of old disease, and two had a history of treated deep vein thrombophlebitis. No patient had prophylactic therapy. The incidence of clinical deep vein thrombophlebitis was zero; noninvasive evaluation in 64 patients demonstrated no abnormality. Postoperative thromboembolism, which occurred in three of 168 (1.8%) patients, was confirmed by ventilation-perfusion scan and pulmonary angiogram. The mortality from thromboembolism was less than 1% (1/168 patients). Extreme obesity may not necessarily constitute a major risk factor in the occurrence of postoperative deep vein thrombophlebitis and thromboembolism. Prophylactic medications and therapy may add inappropriate risk, undue cost, and unnecessary discomfort, and must be weighed against a mortality of less than 1%.

Surgical manipulations of the gastrointestinal system can have a major impact on the ingestive behavior of animals. Particularly well-documented are the feeding and drinking effects of JIB and vagotomy. These two surgical procedures are similar in that they reduce the food intake and body weight of obese animals more than that of lean animals, and of hypothalamic obese rats more than that of genetically obese rats. Intermediate effects are obtained with other obesity models. Given the multiple etiologies of human obesity, it is not surprising that gastrointestinal surgery has variable effects in obese humans. The effects of gastric surgery on the ingestive behavior of animals have received relatively little attention. This is unfortunate because gastric bypass is now one of the most widely used methods for surgical treatment of human obesity. In light of recent developments in gastric surgical techniques and new findings concerning the gastric modulation of food intake, the effects of gastric surgery on the feeding behavior of animals should be further investigated. Much remains to be learned about the physiologic and behavioral mechanisms by which gastrointestinal surgery influences ingestive behavior and body weight. Surgical manipulations of the gastrointestinal system may affect ingestive behavior by directly altering the neural and hormonal feedback signals to the brain from the stomach, intestines, and other organs (liver, pancreas), or they may indirectly alter these feedback signals by modifying the preabsorptive and/or postabsorptive flow of nutrients. Seen from a functional perspective, the gut sends to the brain different types of messages that modulate ingestive behavior. Most attention has focused on gut satiety signals, but the gut can also be the source of painful sensations that suppress ingestive behavior. The distinction between satiety and discomfort is not always clear-cut. For example, gut distention may be satiating when it is moderate, but painful when it is extreme. Nevertheless, the distinction is an important one, and the nature of the feeding-inhibitory effects obtained in animal studies must be carefully evaluated. Ideally, obesity surgery should produce minimal aversive consequences, although whether it is possible to reduce food intake and body weight without producing any discomfort remains to be established. In addition to being a source of feeding-inhibitory cues, the gastrointestinal system may also provide excitatory cues that stimulate feeding and modify food preferences. For example, intestinal infusions of carbohydrates increase subsequent food intake under certain conditions.(ABSTRACT TRUNCATED AT 400 WORDS)
