Coping with cancer: the spouse's perspective

This study explored coping difficulties experienced by wives of patients with a diagnosis of cancer. Concomitantly, the study explored the ways in which nurses intervened to help these wives. This study was designed as an exploratory study. The qualitative analysis made use of data derived from responses to open-ended questions presented to the respondents by the interview method. The study sample consisted of 40 wives who acknowledged experiencing coping difficulties in meeting the demands of everyday living as a result of their husband's diagnosis of cancer. Respondents were selected randomly from seven eligible representative settings located in the Mid-Atlantic region until the desired sample number was reached. Wives, who encountered the unexpected and uncontrollable situation of having a husband with diagnosed cancer, experienced a multitude of coping difficulties. In addition, wives underwent psychological disorganization, disequilibrium, and emotional imbalance. They attempted to cope with the resulting imbalance by using their habitual problem-solving behavior patterns and experienced difficulty when seeking situational supports. This, in turn, added to their stress. Wives also reported that their children had coping difficulties. Wives identified listening, talking, caring, availability of nurses to patients and patients' spouses, sensitivity, empathy, and honesty as essential helpful nursing behaviors. The study underscored the importance of viewing wives of cancer patients as unique systems in need of therapeutic support, and reaffirmed a view of nursing as the art of understanding the unique needs of individuals who are experiencing coping difficulties. This study also underscored the key role of psychiatric liaison nurses in providing supportive therapeutic interventions to the spouses of cancer patients as well as to the nursing staff.     

A patient with right and left atrial membranes: the role of transesophageal echocardiography and magnetic resonance imaging in diagnosis

A patient who had right and left atrial membranes was examined. The diagnosis and the hemodynamic significance of both membranes were detailed by transesophageal echocardiography and were confirmed by magnetic resonance imaging. Transesophageal imaging was found to be superior to routine echocardiography in visualization of these atrial structures.     

Synovial fluid phospholipase A2s and inflammation.

The activation of phospholipase A2 is believed to have an important role in the inflammatory process owing to its induction of eicosanoids, platelet activating factor, and other mediators. Soluble phospholipase A2 has been associated with exudates in different inflammatory conditions. In this review the general physiology and control of this enzyme and, in particular, the most recent findings on human synovial fluid phospholipase A2s are discussed.     

A preliminary report of the short-term effect of carbonated beverage consumption on calcium metabolism in normal women

A variety of nutritional factors influence the bioavailability of calcium and increase a woman's risk of osteoporosis. Eight healthy women completed an 8-week metabolic study designed to investigate the effect of nonalcoholic carbonated beverage consumption on calcium metabolism. Compared with women receiving a control diet, women consuming a diet high in nonalcoholic carbonated beverages demonstrated similar mean serum levels of calcium, ionized calcium, phosphorus, alkaline phosphatase, parathyroid hormone, 1,25-dihydroxyvitamin D3, and osteocalcin. Twenty-four-hour urine volume, creatinine clearance, calcium-creatinine ratio, and phosphorus-creatinine ratio were similar during consumption of the diet high in nonalcoholic carbonated beverages and the control diet. Twenty-four-hour cyclic adenosine monophosphate-creatinine ratio was significantly lower in women consuming the diet high in nonalcoholic carbonated beverage compared with women receiving the control diet (342 +/- 27.4 nmol/mmol vs 409 +/- 22.1 nmol/mmol). Consumption of a diet high in nonalcoholic carbonated beverages on a short-term basis does not appear to affect adversely the serum or urinary markers of calcium metabolism.     

Pulmonary edema in the renal failure patient

A patient with chronic renal failure presenting to the emergency department with acute pulmonary edema has a true life-threatening emergency. Whereas conventional treatment modalities may prove useful, more unusual therapeutic measures may be necessary. A case is presented followed by useful recommendations for the emergency physician faced with such a patient.     

Randomized trial of Codetron for pain control in osteoarthritis of the hip/knee

Patients suffering from pain due to osteoarthritis of the hip and knee participated in a double-blind placebo controlled trial using daily Codetron home care units for 6 weeks over the tibial, saphenous, popliteal and sciatic nerves, and tender points. Seventy-four percent of patients in the real Codetron (Group A) and 28% of the patients in sham Codetron (Group B) improved their pain level more than 25% as measured by visual analogue scale. The difference in pain improvement in the two groups was statistically significant (p less than 0.02 using Fisher's exact probability ratio). Other functional parameters proved to be insensitive to change in this study. This is highly suggestive of beneficial effect of nonhabituating Codetron as a complementary modality in the therapy of chronic pain conditions such as osteoarthritis.     

Echocardiography and cardiac transplantation: a literature review and practical approach

This article reviews the utility of noninvasive echocardiography in the detection of early cardiac transplant rejection before and after the use of cyclosporine. It addresses the use of Doppler and two-dimensional echocardiography in the routine cardiac evaluation of the heart-transplant patient, including the use of two-dimensional echocardiography in guiding the endomyocardial biopsy procedure.     

Acute recognition and management of congestive heart failure

The acute recognition and management of CHF is challenging. A basic understanding of the determinants of cardiac performance and myocardial O2 consumption along with the pathophysiology of CHF is essential knowledge for the physician undertaking to treat this serious disorder. The basic value of the patient history and physical examination along with assessment of noninvasive tests remains unquestioned, but in addition much relevant and sophisticated information can be gained by invasive hemodynamic monitoring. The cardiopulmonary profile generated by such monitoring allows the physician to use specific hemodynamic and circulatory data for the purpose of manipulating these variables favorably for the heart and circulation. A wide array of therapeutic options is currently available, but, in general, respiratory support and pharmacotherapy are the mainstays of treatment. The traditional agents like digitalis and diuretics have assumed a lesser role during the last decade because of the availability of potent new vasodilator and inotropic agents. In addition, certain mechanical, procedural, and surgical options can be used if circumstances are urgent. In the final analysis, physicians who manage these patients must possess strong cognitive skills but also the clinical reflexes to carry them out: for every hemodynamic and circulatory action, they must be prepared to counter quickly and decisively with a clinical reaction which utilizes these principles to optimize cardiac function. It is hoped that the strategies presented in this article will allow them to perform in such a manner.     

Ingestion of immune bloodmeals and infection of Aedes fowleri, Aedes mcintoshi, and Culex pipiens with Rift Valley fever virus

Rift Valley fever (RVF) virus infection, dissemination, and transmission rates were determined for Aedes fowleri, Aedes mcintoshi and Culex pipiens 7 or 10 days after sequentially feeding to repletion on RVF virus immune hamsters and RVF viremic hamsters, or after feeding on a mixture of RVF virus immune sheep serum and RVF viremic hamster blood through a pledget. No significant differences in infection or dissemination rates were detected among Ae. fowleri and Cx. pipiens feeding to repletion on immune hamsters before or after feeding to repletion on a viremic hamster. Similarly, no significant differences in infection, dissemination, or transmission rates were observed among Ae. fowleri and Cx. pipiens feeding to repletion on immune hamsters or nonimmune (control) hamsters 0 or 24 hr after inoculation with RVF virus. Infection rates were significantly higher for Ae. fowleri (56/66, 85%) and Cx. pipiens (123/148, 83%) fed only on viremic hamsters than for those interrupted to complete feeding on an immune hamster (Ae. fowleri [24/49, 59%], Cx. pipiens [66/131, 50%]) or a nonimmune hamster (Ae. fowleri [32/51, 63%], Cx. pipiens [69/127, 54%]). However, no significant differences were detected in infection, dissemination, or transmission rates among Ae. fowleri, Ae. mcintoshi or Cx. pipiens fed on a viremic hamster and interrupted to complete feeding on an immune vs. a nonimmune hamster. Results from interrupted feeding experiments were significantly different from pledget feeding experiments.(ABSTRACT TRUNCATED AT 250 WORDS)
