Water, mineral waters and health.

The authors focus on water resources and the use of mineral waters in human nutrition, especially in the different stages of life, in physical activity and in the presence of some morbid conditions. Mineral water is characterized by its purity at source, its content in minerals, trace elements and other constituents, its conservation and its healing properties recognized by the Ministry of Health after clinical and pharmacological trials. Based on total salt content in grams after evaporation of 1l mineral water dried at 180 degrees C (dry residues), mineral waters can be classified as: waters with a very low mineral content, waters low in mineral content, waters with a medium mineral content, and strongly mineralized waters. Based on ion composition mineral waters can be classified as: bicarbonate waters, sulfate waters, sodium chloride or saltwater, sulfuric waters. Based on biological activity mineral waters can be classified as: diuretic waters, cathartic waters, waters with antiphlogistic properties. Instructions for use, doses, and current regulations are included.

Communication strategies and interpersonal skills of instructors of esophageal speech: an observation study.

OBJECTIVE: In this article, the way that the Instructor of Esophageal Speech (IES) works is considered from an interactive-analytic perspective. METHODS: The observation project data were gathered during 6 months in 2004 at the training sessions of the Ginreikai-Asian Federation of Laryngectomees' Association using the Six Category Intervention Analysis framework (6CIA) by a trained communication specialist as an active-observer. RESULTS: Mean scores of each of the six categories and a series of percentage distributions were extracted from the usage-frequency data and interpreted together with the results of Chi-square analysis of usage-frequency units. We found the IES used more frequently authoritative categories and used less facilitative categories. Our results of the data analysis show that the 30 IES used more authoritative interventions and used more frequently the prescription and information giving than the confrontation or cathartic interventions. CONCLUSION: The results of the present study show that the 6CIA framework has its potential and value as an analytic tool to explore the IES' actual behavior in a specific therapy related context. PRACTICE IMPLICATIONS: We argue for the utility of the 6CIA as an analytic framework to investigate the interpersonal behavior of the IES in the Japanese cultural setting.

Multislice CT colonography: current status and limitations.

CT colonography (CTC) is a promising method for colorectal cancer screening because it provides a full structural evaluation of the entire colon. It has a superior safety profile, a low rate of complications, and high patient acceptance. In addition, CTC offers the real possibility of eliminating the cathartic bowel preparation, one of the biggest obstacles to patient compliance with colorectal cancer screening. Results of CTC studies in recently published literature are extremely encouraging, demonstrating that this method of screening can detect lesions equal to or larger than 8 mm with few false-positive findings.

Castor bean (Ricinus communis) toxicosis in a sheep flock.

This paper describes clinical, laboratory and pathological findings of sheep, which is intoxicated with castor bean. The source of intoxication was a miscellaneous garden waste. Forty-five animals showed clinical toxicosis and 17 died. The clinical signs included weakness, salivation, profuse watery diarrhoea, dehydration, mydriasis, teeth grinding, hypothermia and recumbency. The most significant haematological and biochemical findings were a high haematocrit, high concentration of serum BUN, creatinine and phosphorus and high activity of serum CK and AST. Pathology revealed severe gastroenteritis, cardiac haemorrhage and necrosis, hepatic necrosis and acute tubular necrosis in kidneys. Treatment included symptomatic and supportive care with fluid therapy and cathartic administration.

Stool screening for colorectal cancer: evolution from occult blood to molecular markers.

BACKGROUND: Colorectal cancer is the second leading cause of malignant death, and better preventive strategies are needed. Participation rates for colorectal cancer screening remain low due, in part, to perceived discomfort, potential harm, and high costs with available tools. METHODS: Stool testing, unlike other conventional screening approaches, is noninvasive and requires no cathartic preparation. However, widely used fecal blood tests yield frequent false-negative and false-positive results that lower screening effectiveness and raise program costs. There is a compelling biological rationale to target DNA alterations exfoliated from neoplasms into stool, and multiple DNA markers would need to be assayed because of the genetic heterogeneity of colorectal neoplasia. Early clinical studies with this multi-target DNA-based stool assay approach suggest high sensitivity for both colorectal cancer and premalignant adenomatous polyps while maintaining high specificity. CONCLUSIONS: This apparently accurate and user-friendly new approach holds promise to improve the effectiveness, efficiency, and appeal of colorectal cancer screening. Large-scale clinical studies are clearly warranted to corroborate the early results.

Conjugated bile acid replacement therapy for short-bowel syndrome.

BACKGROUND & AIMS: Although fat malabsorption in the short-bowel syndrome is caused in part by decreased bile acid secretion, bile acid replacement therapy is not used because of the belief that ingested bile acids would worsen diarrhea, outweighing the benefits of improved fat absorption. This study compared the effect of a natural conjugated bile acid mixture from ox bile with that of cholylsarcosine, a synthetic conjugated bile acid, on fat absorption and diarrhea in a patient with the short-bowel syndrome. Cholylsarcosine is resistant to bacterial metabolism and has no cathartic activity. METHODS: Metabolic balance studies and a clinical trial were performed in an emaciated patient with the short-bowel syndrome and ileostomy in whom parenteral nutrition could not be used. RESULTS: In balance studies, conjugated bile acid replacement therapy with either preparation caused fat absorption to increase by approximately 40 g/day. Calcium absorption also increased. Neither bile acid product caused a clinically significant increase in ileostomy water output. During a 4-month outpatient trial, while the patient ingested 2 g/meal natural bile acids, her weight increased from 80 to 98 lb, without side effects. CONCLUSIONS: Conjugated bile acid replacement therapy should be part of the armamentarium for the treatment of selected patients with the short-bowel syndrome.

Student nurses perceptions of their interpersonal skills: a re-examination of Burnard and Morrison's findings.

Heron's six category intervention analysis is a component of many counselling courses and is used extensively by teachers of interpersonal skills within nursing curricula. The popularity of this framework has generated a number of studies which have attempted to offer empirical support for the theory. The aim of this study was to re-evaluate some of these findings. Utilising an earlier research instrument, a set of findings are offered and comparisons made with previous work. Our findings suggest that student nurses perceive themselves to be most skilled in the use of supportive, prescriptive and cathartic interventions and least skilled in the use of informative, catalytic and confronting interventions. A discussion of the new findings and their implications is offered.

Improved water and sodium absorption from oral rehydration solutions based on rice syrup in a rat model of osmotic diarrhea.

Rice syrup solids, rice protein, and casein hydrolysate were added to experimental oral rehydration solutions in various combinations and tested in a rat intestinal perfusion system. Chronic osmotic diarrhea was induced in juvenile rats by supplying the cathartic agents, magnesium citrate and phenolphthalein, in their drinking water for 1 week. The experimental oral rehydration solutions were compared with standard oral rehydration solutions containing 20 gm/L or 30 gm/L of glucose and with each other to determine if there were significant differences in net water, sodium, or potassium absorption. An oral rehydration solution containing 30 gm/L of rice syrup solids had a net water absorption rate significantly higher than that of the standard 20 gm/L glucose-based oral rehydration solution (2.1 +/- 0.62 versus 1.5 +/- 0.48 microliters/[min x cm], p less than 0.05). Casein hydrolysate did not significantly affect net water absorption. However, combinations of 30 gm/L rice syrup solids and 5 gm/L casein hydrolysate significantly increased (p less than 0.05) net sodium and potassium absorption compared with the 20 gm/L glucose-based oral rehydration solution but not versus rice syrup solids alone. Oral rehydration solutions containing 30 gm/L rice syrup solids plus 5 gm/L rice protein, and 30 gm/L rice syrup solids plus 5 gm/L casein hydrolysate, had net water absorption rates significantly higher than the rate of a 30 gm/L glucose-based oral rehydration solution (2.5 +/- 0.36 and 2.4 +/- 0.38, respectively, versus 0.87 +/- 0.40 microliters/[min x cm], p less than 0.05). Rice protein and casein hydrolysate, however, did not significantly affect net water, sodium, or potassium absorption when added to rice protein glucose-based oral rehydration solutions. An inverse correlation between osmolality and net water absorption was observed (r = -0.653, p less than 0.02). The data suggest that substitution of rice syrup solids for glucose in oral rehydration solutions will improve water absorption and that rice syrup solids in combination with protein hydrolysates may, in addition, promote better sodium and potassium uptake.

Tricyclic antidepressant overdose.

Overdose of a tricyclic antidepressant is a serious and all-too-frequent occurrence. The diagnosis must be considered in known or suspected overdoses, and signs such as a dry axilla, tachycardia, and wide QRS must be specifically sought. Management depends upon support of vital functions and a thorough understanding of the pharmacology of the drug. Emptying the gastrointestinal tract with ipecac or lavage and hastening elimination with activated charcoal and a cathartic are extremely important measures. Cardiac arrhythmias generally respond to sodium bicarbonate, and seizures respond to intravenous diazepam. Neither physostigmine nor dialysis are considered to be treatments of choice. As in other overdoses, counseling to prevent ingestions is more than worth "a pound of the cure."

Colonoscopic diagnosis and treatment of lower gastrointestinal bleeding.

Methods of diagnosis and treatment of lower gastrointestinal bleeding depend on the rate of bleeding and the amount of blood lost. If bleeding is occult, colonoscopy is the single best way to determine the source, if bleeding is gross but mild, causing melena or small amounts of hematochezia, colonoscopy or a combination of flexible sigmoidoscopy and double-contrast barium enema should be used to evaluate the colon. In most patients with melena, the upper tract must be examined endoscopically. Acute lower gastrointestinal bleeding stops spontaneously in 75 to 90 per cent of patients, permitting preparation of the colon before colonoscopy. If bleeding is continuing, diagnostic options include colonoscopy with no preparation of the colon, relying on the cathartic effect of blood, or a red cell radionuclide scan followed by angiography if the scan is positive. A bleeding lesion seen on angiography is usually treated by infusion of vasopressin. Colonoscopic treatment of a bleeding site uses the BICAP probe, heater probe, or argon laser. Patients who bleed severely and those who do not respond to treatment or rebleed after treatment are candidates for operation. Segmental resection is preferred if the bleeding site is known. If not, total colectomy with ileorectal anastomosis may be necessary. A mortality rate of 10 to 15 per cent in patients with severe bleeding reflects the advanced age of many of these patients and the difficulty of managing gastrointestinal bleeding in the presence of associated medical conditions.

Parental accounts regarding the physical punishment of children: discourses of dis/empowerment.

OBJECTIVE: In the light of the psychological literature (e.g., Bettleheim, 1987) which indicates various contradictions surrounding the talk about and practice of the physical punishment of children (PPC), the main aim of the present study is to identify and examine the rationale(s) used by parents which bolster(s) PPC. METHODOLOGY: Data collection--semistructured interviews carried out with 10 parents (nine female, one male). Data analysis--discourse analysis (e.g., Potter & Wetherall, 1987), a form of qualitative data analysis which is sensitive to the range and complexity of accounts (or discourses) presented by participants. Hence, we explore the various (often conflicting) discourses deployed by parents while talking about PPC, an approach which has not been used before in the study of parental discipline. RESULTS: Various oppositional discourses were used by the parents, each of which implies diverse justifications and consequences. Four in particular were identified--PPC as (1) pedagogic (educational). (2) cathartic (need relief); (3) individualistic (power assertion); (4) cyclical (reproduction)--and five instances of contradiction explicated with reference to the particular discursive context. CONCLUSION: Much confusion and complexity regarding PPC is evident from parental talk which is marked by discursive variation and contradiction. These discursive collisions notwithstanding, the participant's discourse generally implies the oppressive positioning of children and, consequently, offers support for physical punishment. The study also highlights the utility of discourse analysis as a method for interrogating PPC--and indeed other phenomena related to child abuse and neglect.

Failure of gastric emptying and charcoal administration in fatal sustained-release theophylline overdose: pharmacobezoar formation.

We report the case of a fatal theophylline overdose from a sustained-release preparation in a 54-year-old woman. Initial serum theophylline concentration was 31.3 mg/L. Manifestations of mild toxicity cleared in the emergency department after treatment with gastric lavage, charcoal, and a cathartic. A life-threatening overdose was not suspected, and the patient arrested eight hours after discharge from the ED. At autopsy, her serum theophylline concentration was 190.1 mg/L. A white, waxy mass weighing 318.8 g and containing 29 g theophylline, representing the residue of many sustained-release tablets, was found in her stomach. This case reinforces the importance of obtaining repeat serum theophylline levels in patients with sustained-release theophylline overdose. Gastric pharmacobezoar formation should be considered in cases of sustained-release theophylline overdose with rising theophylline levels and patient deterioration, despite adequate gut decontamination.

Trazodone overdose.

Trazodone did not appear to be a potent respiratory depressant or cardiotoxic or neurotoxic agent in our cases. Further experience is needed to determine a recommended treatment procedure. It is not clear whether the experience with these two cases can be extrapolated to elderly patients, patients with serious physical illnesses, or cases involving larger ingestions. Additional information is required concerning concurrent ingestion of trazodone and alcohol or other CNS-depressant drugs. It would appear that standard treatment including emptying of the stomach, activated charcoal and cathartic, and close observation to monitor and support the respiratory and cardiovascular systems is appropriate. These two case reports suggest that trazodone lacks the serious toxicity encountered with other antidepressant compounds when taken in large overdoses.

Effect of whole-bowel irrigation on the antidotal efficacy of oral activated charcoal.

Whole-bowel irrigation was studied in three volunteer subjects and compared with oral activated charcoal as a gastrointestinal decontamination procedure for acute drug overdose. The volunteer subjects were given 650 mg aspirin and were assigned randomly to the following treatment groups: 24-hour urine collection only; immediate whole-bowel irrigation with a polyethylene glycol solution; 50 g oral activated charcoal followed by whole-bowel irrigation; and oral activated charcoal alone. The cumulative 24-hour urinary salicylate excretion was measured in each trial. Catharsis was achieved rapidly with whole-bowel irrigation. Oral activated charcoal without catharsis was most effective in decreasing aspirin absorption (P = .011). These results do not support the routine use of a cathartic in combination with oral activated charcoal.

Button battery ingestions.

Although ingestions of button batteries can have serious complications, the majority of these ingestions will be benign. Button batteries that lodge in the esophagus should be removed immediately by endoscopy. Other ingestions can be managed with observation at home unless symptoms develop. Weekly radiographic examinations should be done to follow the progression of the button battery in these patients. The expected threat of mercury toxicity has not materialized. Patients who ingest mercury-containing button batteries should undergo chelation therapy and monitoring of levels only if symptoms characteristic of mercury toxicity develop. Cathartics and water-soluble enemas, although not indicated for intact button batteries, may be useful in speeding transit of mercury if it is released into the bowel. Other metals present in button batteries appear to pose no health threat.

Extracorporeal bypass for the treatment of verapamil poisoning.

A 25-month-old boy ingested six sustained-release verapamil tablets, each containing 240 mg of drug. Charcoal and cathartic were given but were never passed per rectum. Third-degree heart block, hypotension, and hypocalcemia were only transiently responsive to calcium infusions, inotropic agents, and epicardial pacing. Cardiopulmonary arrest with electromechanical dissociation ensued. Standard cardiopulmonary bypass was used to allow sufficient time for liver detoxication. Serum levels of verapamil fell during the bypass procedure, and the patient's cardiac status improved. However, continued absorption of drug after bypass resulted in a level of 4 mg/L, unresponsive circulatory failure, and death. Early, aggressive gut decontamination and the potential value of cardiopulmonary bypass procedures in poisoning that lead to cardiac depression are emphasized.

Student nurses' use of their interpersonal skills within clinical role-plays.

Heron's six-category intervention analysis is a component of many counselling courses and is used extensively by teachers of interpersonal skills within nursing curricula. In addition, researchers have used six-category intervention analysis as a theoretical framework for exploring nurses' perceptions of their interpersonal skills. This study aimed to advance previous research by using Heron's framework to analyse student nurses' actual skills, as deployed in clinical role-plays, and then to compare them to earlier findings. Analysis of the data produced the following rank order of interventions based on Heron's framework: catalytic, prescriptive, supportive, informative, confronting and cathartic. The findings both challenge and support previous findings on nurses' perceptions of their interpersonal skills. The paper discusses these findings and their implications for clinical practice.
