Prevalence of encysted apicomplexans in muscles of raptors.

An acid-pepsin digestion technique was used to examine portions of breast muscle and heart from raptors for encysted protozoans. Apicomplexan zoites were present in 52 (45.6%) of the 114 samples examined: 11 of 12 (91.7%) red-shouldered hawks (Buteo lineatus), 20 of 34 (58.8%) red-tailed hawks (Buteo jamaicensis), two of seven (28.6%) Cooper's hawks (Accipiter cooperi), three of four (75%) sharp-shinned hawks (Accipiter striatus), one (100%) Mississippi kites (Ictinia misisippiensis), one of two (50%) American kestrels (Falco sparverius), one bald eagle (Haliaeetus leucocephalus), one of two (50%) golden eagles (Aquila chrysaetos), one of three (33%) turkey vultures (Cathartes aura), two of three (66.7%) black vultures (Coragyps atratus), three of six (50%) great-horned owls (Bubo virginianus), five of 15 (33.3%) barred owls (Strix varia), and one of 12 (8.3%) screech owls (Asio otus). Encysted protozoans were not observed in digests of tissues from three broad-winged hawks (Buteo platypterus), four ospreys (Pandion haliaetus), and five barn owls (Tyto alba). Apicomplexan cysts resembling Sarcocystis species were observed in tissue sections of muscles from 28 (37.8%) of 74 raptors.

Probiotics can treat hepatic encephalopathy.

Hepatic encephalopathy (HE) is a common and dreaded complication of liver disease. The effects of HE can range from minimal to life threatening. Even 'minimal HE' causes major dysfunction in many aspects of daily living. The exact pathogenesis of HE remains unknown. However, the products of gut flora metabolism are universally recognized as critical. Present treatments for HE include the cathartic agent lactulose and poorly absorbable antibiotics. While effective, these treatments incur numerous side-effects and cost. Probiotics are viable bacteria given orally to improve health. Probiotics have multiple mechanisms of action that could disrupt the pathogenesis of HE and may make them superior to conventional treatment.

Treatment of impaction colics.

Impactions have been reported in the stomach and all segments of the intestine. Impactions predominately occur just oral to sites of intestinal narrowing or active pacemakers. The most common sites of impaction are in the ileum, the cecum, and the large colon pelvic flexure. The treatment of gastrointestinal impactions depends on the segment affected and the amount of bowel damage which has occurred from distension. Many impactions respond to appropriate administration of analgesics, cathartics, and oral or intravenous fluids. The prognosis for impactions treated medically is better than for those which require surgery.

The future of colorectal imaging: computed tomographic colonography.

The development of colorectal cancer screening alternatives that are attractive to patients and effective for screening is critical for reducing this too-common and deadly disease. CTC is an exciting technique that is the only imaging alternative developed since the barium enema for colon screening. In the past few years, many obstacles to clinical implementation of CTC have been eliminated. For example, there is no longer any post-processing time, which was previously as long as 8 to 10 hours, and the interpretation time has been drastically reduced from 4 hours to 15 to 20 minutes. The majority of studies have demonstrated excellent results for detection of lesions > or = 1 cm, with few false positives. This examination will continue to improve with the development of automated (computer) detection programs and automated 3D rendering algorithms. In addition, cathartic bowel preparation, one of the biggest obstacles to patient compliance with colorectal cancer screening, may be eliminated if successful fecal tagging can be developed. The most important issue that remains is its performance in a screening population, and studies are currently underway to answer that important question.

Tarantism, dancing mania and demonopathy: the anthro-political aspects of 'mass psychogenic illness'.

This study questions the widely held assumption that the phenomenon known as mass psychogenic illness (MPI) exists per se in nature as a psychiatric disorder. Most MPI studies are problematical, being descriptive, retrospective investigations of specific incidents which conform to a set of pre-existing symptom criteria that are used to determine the presence of collective psychosomatic illness. Diagnoses are based upon subjective, ambiguous categories that reflect stereotypes of female normality which assume the presence of a transcultural disease or disorder entity, underemphasizing or ignoring the significance of episodes as culturally conditioned roles of social action. Examples of this bias include the mislabelling of dancing manias, tarantism and demonopathy in Europe since the Middle Ages as culture-specific variants of MPI. While 'victims' are typified as mentally disturbed females possessing abnormal personality characteristics who are exhibiting cathartic reactions to stress, it is argued that episodes may involve normal, rational people who possess unfamiliar conduct codes, world-views and political agendas that differ significantly from those of Western-trained investigators who often judge these illness behaviours independent of their local context and meanings.

Bulimia nervosa in Rochester, Minnesota from 1980 to 1990.

Numerous studies have estimated the frequency of bulimia nervosa among high school girls and college women, but population-based trends in incidence in a community have not been reported. In this study we determined the incidence of bulimia nervosa by identifying persons residing in the community of Rochester, Minnesota, who had the disorder initially diagnosed during the 11-year period from 1980 to 1990. Using our comprehensive population-based data resource (the Rochester Epidemiology Project), we identified cases by screening 777 medical records with diagnoses of bulimia; feeding disturbance; rumination syndrome; adverse effects of cathartics, emetics, or diuretics; polyphagia; sialosis; or vomiting. We identified 103 Rochester residents (100 female and 3 male) who fulfilled DSM-III-R diagnostic criteria for bulimia nervosa during the 11-year study period. Mean +/- S.D. age for females at the time of diagnosis was 23.0 +/- 6.1 years (range, 14.4 to 40.2 years). Yearly incidence in females rose sharply from 7.4 per 100000 population in 1980 to 49.7 in 1983, and then remained relatively constant around 30 per 100000 population. The annual age-adjusted incidence rates were 26.5 per 100000 population for females and 0.8 per 100000 population for males. The overall age- and sex-adjusted annual incidence was 13.5 per 100000 population. Bulimia nervosa is a common disorder in adolescent girls and young women from 15 to 24 years of age. Histories of alcohol or drug abuse, depression, or anorexia nervosa were higher than expected in the general population.

Aloe exudate: characterization by reversed phase HPLC and headspace GC-MS.

From the leaves of aloe, a succulent plant, a dried exudate commonly called aloe can be obtained, which is used as a natural drug for its cathartic effect and is widely employed as a bittering agent in alcoholic beverages. This investigation provides a tentative characterization of several commercial aloe exudates carried out both by reversed phase HPLC and by headspace GC-MS analysis. By means of HPLC the derivatives were evaluated, and by GC-MS the volatile fraction was investigated. Qualitative and quantitative differences among the constituents in various samples of different origins were found. In particular, these were evident in the HPLC profile of Kenya aloe and an Aloe barbadensis sample, which exuded a high content of isoaloeresin D and aloins, whereas GC-MS analysis showed the presence of anisole exclusively in Kenya aloe samples. Moreover, the results obtained by means of the latter technique suggested a reason for the prevailing use of Mosselbay and Port Elizabeth aloes in bitter spirits formulation.

A multiple case study of rape victim advocates' self-care routines: the influence of organizational context.

This study assumes that rape victim advocates who provide community outreach services to victimized women must adjust to a heightened awareness of sexual violence to do their jobs. Using qualitative methodology, this multiple case study explored rape victim advocates' strategies for incorporating repeated exposure to sexual assault into their daily lives as well as ways that organizations can support such endeavors. Findings suggest that advocates' self-care routines draw upon various personal resources (i.e., cognitive, physical, social, spiritual, verbal), and serve 2 roles for coping with rape-related pain: (a) cathartic releasing of traumatic material, and (b) improving capacity to integrate the traumatic material into one's life. Additionally, over 20 organizational characteristics that workers perceive to be supportive (e.g., weekly meetings, flexible hours) were identified. Nonparametric and categorical statistical analyses were used to analyze the relationship between organizational support and self-care routines, finding that advocates working in organizations with higher levels of support utilize more strategies that are integrative in nature. Implications of these findings are discussed.

Age differences in the response of California ground Squirrels (Spermophilus beecheyi) to avian and mammalian predators.

The antipredator behavior of juvenile and adult California ground squirrels (Spermophilus beecheyi) was videotaped in Experiment 1 to measure the effects of age on assessment of a briefly presented live dog and a model red-tailed hawk (Buteo jamaicensis) in simulated flight. Adult squirrels treated the hawk as more dangerous than the dog, whereas juvenile squirrels showed less differentiation of the predator types. Juvenile squirrels also perceived the dog as a more immediate danger than adult squirrels did. For Experiment 2, the red-tailed hawk model was compared with models of a nonthreatening turkey vulture (Cathartes aura) and crow (Corvus brachyrhynchos). Neither age class differentiated the avian models; however, the adult squirrels treated these birds as more threatening than the juvenile squirrels did. Both studies suggest that learning may contribute to predator assessment.

The effects of magnesium on ion transport in short-circuited rabbit terminal ileum.

The effects of MgCl2 on the electrical characteristics and sodium and chloride transport in short-circuited rabbit terminal ileum in vitro were studied. Increasing the magnesium concentration from a basal concentration of 1.1 mmol/l to either 2.5 or 10.3 mmol/l (mucosal or serosal addition) resulted in increases in the unidirectional flux of chloride from serosa to mucosa (JCl sm), short-circuit current (SCC) and transmucosal potential difference (p.d.). Increasing the magnesium concentration from a low basal concentration (0.3 mmol/l) to 10.3 mmol/l (mucosal or serosal addition) abolished net sodium absorption and converted net chloride absorption into net secretion, as a result of a decrease in the unidirectional flux of sodium from mucosa to serosa (JNa ms), and increases in the unidirectional fluxes of sodium and chloride from serosa to mucosa (JNa sm and JCl sm). Increases in SCC and p.d. occurred after mucosal, but not serosal, addition of magnesium. Incubation of stripped ileal mucosa with MgCl2 (10.3 mmol/l) did not result in increased mucosal concentrations of cAMP or cGMP. These data suggest that at least part of the cathartic effect of magnesium salts is likely to result from marked changes in ileal ion transport and provide a rational explanation for the watery diarrhoea commonly seen after the oral administration of magnesium salts to hypomagnesaemic patients.

Catharsis: an investigation of its meaning and nature.

Nurses commonly use catharsis and cathartic techniques as part of their clinical practice to enable clients and themselves to release emotion, to feel better and to facilitate coping. However, the literature does not provide clinical nursing evidence for its use. The main purpose of the investigation is to examine the beliefs about and understanding of catharsis which two groups of nurses hold: one group of nurse teachers and one group of nursing students. One hundred and forty-two respondents completed self-administered questionnaires asking about their understanding of and beliefs about catharsis as being beneficial, social, negative or psychotherapeutic in nature. The possible relationship of their answers to age, sex, philosophical orientation and qualifications was deemed to be important. The results suggest nurses understand that catharsis is related to emotion and has a psychotherapeutic purpose. However, there appear to be gaps in their understanding. Nurses also seem to believe that the release and expression of emotions is more acceptable for women than for men. There is also evidence that the more experienced nurses think differently from less experienced nurses, placing more emphasis on behaviour rather than emotion as they grow older. The problems associated with catharsis are discussed along with the implications for research and practice.

Suicide: a personal reflection.

One of the authors of this paper, Carla Diedrich, had a personal experience of suicide in her family. She wants to both share the experience and allow the circumstances to be directive and informative for individuals who have had similar experiences with suicide and for those working in a clinical capacity. In this sense, the work belongs to Carla and her family and has been significant, almost cathartic, in helping her especially deal with this difficult set of personal circumstances.

Angel trumpet lily poisoning in five adolescents: clinical findings and management.

OBJECTIVE: To describe clinical features and management of Angel trumpet lily poisoning in adolescents. METHODOLOGY: Case notes of five adolescent males who presented to the emergency department of a teaching hospital were reviewed. RESULTS: All five boys ingested a mixture of coca-cola and a brew prepared by boiling the leaves and flowers of the plant. They presented to the emergency department with various degrees of agitation and confusion and specific clinical signs. All were treated with charcoal and cathartics and discharged after 36 h. CONCLUSIONS: Due to its hallucinogenic effects, abuse of Angel trumpet lily is not uncommon and should be suspected in adolescents presenting with altered mental state and hallucinations in conjunction with other anticholinergic symptoms and signs.

Effectiveness of hemodialysis in the extracorporeal therapy of phenobarbital overdose.

Most patients with phenobarbital overdose can be adequately treated with general supportive care, cathartics, activated charcoal, and a forced alkaline diuresis. In severely compromised patients, both hemodialysis and hemoperfusion have been used to enhance elimination of the drug. Of these two therapies, hemoperfusion is generally considered to be more effective because phenobarbital shows significant protein binding. Prior reports describing the use of hemodialysis in the treatment of phenobarbital overdose used small low-efficiency dialyzers at much lower blood flow rates compared with what is available today. In this report, a patient with life-threatening phenobarbital overdose is described who was treated with hemodialysis. This is the first reported case describing the effects of a high-efficiency dialyzer using high blood flow rates on phenobarbital pharmakokinetics. Using this technique, the clearance of phenobarbital was found to be greater than what has been previously reported with hemodialysis and greater than most reported cases describing the use of hemoperfusion. The procedure was associated with a rapid fall in phenobarbital levels and a dramatic improvement in the patient's clinical condition. The findings in this case show that use of a high-efficiency dialyzer with high blood flow rates is an effective therapy for patients with life-threatening phenobarbital poisoning. The excellent clearance of phenobarbital shown in this case, combined with the lack of thrombocytopenia, more widespread availability, and greater familiarity by the staff who administer it, support the idea that hemodialysis should be considered the preferred mode of extracorporeal therapy for phenobarbital intoxication.

Surgical management of chronic unremitting constipation and fecal incontinence associated with megarectum: A preliminary report.

BACKGROUND/PURPOSE: Functional constipation with associated fecal incontinence responds poorly to medical management once megarectum has developed. The authors describe resecting the dilated rectum and inserting a cecostomy button for antegrade enemas in this difficult condition. METHODS: Four children, ages 9 to 15 years, with a history of unremitting constipation and fecal incontinence were referred for evaluation after not responding to medical management. All patients had exhibited normal lumbosacral magnetic resonance images (MRI) and open rectal biopsies; however, all 4 patients had a megarectum on contrast enema. In addition, anorectal manometry was consistent with functional fecal retention. The dilated rectum was resected by anastamosing the nondilated sigmoid colon to the distal rectum, and a standard gastrostomy button was inserted into the cecum for antegrade enemas. Mean follow-up was 35 months (range, 8 to 60 months). RESULTS: Constipation and incontinence resolved within 6 months in all patients, and all children remained continent without the aid of cathartic agents. There were no postoperative episodes of fecal impaction. The only complication was antibiotic-associated diarrhea in 1 patient. Cecostomy buttons were removed at 1 year postplacement in all 4 patients with continued success. Three patients underwent repeat anorectal manometry; all 3 had normal rectal sensory threshold volumes and anorectal inhibitory reflexes. Barium studies also were obtained in the 3 patients without evidence of recurrent rectal dilation. CONCLUSIONS: Refractory constipation and incontinence associated with megarectum may be amenable to surgical intervention in selected patients. The authors' limited experience suggests that proctectomy and button cecostomy is an effective treatment option that improves the quality of life in these patients. Furthermore, proctectomy alone may be curative.

[The lethal ingestion of cigarettes in adults: does it really exist?].

HISTORY AND ADMISSION FINDINGS: A 35-year old patient suffering from a borderline personality disorder was admitted to our clinic with ingestions of cigarettes seven times within 15 months. The patient showed symptoms of a nicotine intoxication with agitation, hypertension, tachycardia, dizziness and nausea after ingestion of 7 up to 20 cigarettes. DIAGNOSIS: Mild nicotine intoxication. TREATMENT AND COURSE: After therapy with gastric lavages, activated charcoals and saline cathartics forced acid diuresis were performed in all seven cases of intoxication. All courses were without complications and unit every time the patient could be transferred to the psychiatry within 24 hours after the hospitalization in our clinic. CONCLUSION: An ingestion of more than 6 cigarettes is considered a life-threatening intoxication for adult persons. In spite of the ingestion of 7 up to 20 cigarettes our patient never showed any symptoms of a severe or life-threatening nicotine intoxication. In the last decades no lethal nicotine intoxication after ingestion of cigarettes in adults was published in the literature.

Effects of long-term administration of Senna occidentalis seeds in the large bowel of rats.

Plants of the genus Senna that contain anthranoides derivatives are frequently used as cathartics. Radiological studies have demonstrated that patients with chronic constipation who have used stimulant laxative have colonic redundancy and dilatation more frequently than patients who have not. The objective of the present work was to study morphological and histochemical changes of the lower gut after administration of Senna occidentalis seeds for a long period to rats, as observed in skeletal muscle fibers. Fragments of the lower gut of young and adult rats treated with S. occidentalis seeds (2% for 171 days and 3% for 61 days in the diet) were submitted to histological and histochemical analysis and to densitometry. The most important finding was decreased oxidative enzyme activity in smooth muscle cells and in myenteric neurons of the large bowel. As oxidative metabolism is essential for ATP and energy production, these results suggest that the functional intestinal disturbance caused by the chronic use of Senna occidentalis as a laxative can be due to a metabolic effect involving energy production, which would decrease colonic motility and cause functional colonic dilatation, but without any irreversible anatomic change.

Multiple personality disorder and iatrogenesis: the cautionary tale of Anna O.

An examination of Breuer's treatment of Anna O. illustrates some of the controversies surrounding the recent rise of case reports of multiple personality disorder. Anna O., the first patient of the cathartic method, psychoanalysis, and dynamic psychiatry, fits current criteria for multiple personality disorder. Breuer's treatment, however, may have contributed to her states of absence; the timing, type, and intensity of Breuer's interventions make it possible that he unwittingly encouraged and amplified Anna's dissociations, reified her ego fragments, and then explained Anna's symptoms with the pseudomemories and confabulations recovered from Anna while she was hypnotized. A review of Breuer's treatment highlights some of the controversial aspects of multiple personality disorder, specifically its possible vulnerability to iatrogenesis via suggestion and unconscious collusion and other factors. The current stance of some multiple personality disorder enthusiasts, opaque to their participation in interactions that may lead to certain patient productions, resembles the older psychoanalytic stance exemplified by the early Breuer and Freud. The dialectic of the therapist as a neutral observer versus as an influential participant continues to be a focus of controversy, both within psychoanalysis and psychotherapy and in the understandings of the etiology and treatment of multiple personality disorder.
