Bilateral rupture of diaphragm with delayed strangulation

A 64-year-old woman presented in shock. The computed tomography (CT) scan confirmed rupture of the left diaphragm with strangulation. Three days after surgery, the patient developed herniation of abdominal contents on the right side with cardiorespiratory collapse. Marlex mesh was used to repair on the right side. Postoperatively, she needed partial gastrectomy for massive duodenal ulcer bleeding. A dual chamber pacemaker was used to correct the complete heart block.     

Retrosternal epiphyseal disruption of medial clavicle: case and review in children

Retrosternal dislocations of the clavicle have been reported previously in adults throughout the orthopedic literature. However, in children few cases have been noted in either the pediatric, emergency, or orthopedic literature. The potential for great vessel injury as well as acute airway compromise makes the retrosternal disruption of the sternoclavicular joint a surgical emergency that must be diagnosed quickly. Diagnosis is enhanced by the cephalic tilt view and by computed tomography (CT scan), as planar x-ray and tomography do not always reveal this potentially life-threatening condition. Surgical consultation must be sought acutely; however, management may need to begin prior to definitive repair. Emergency management begins by suspecting the injury, and with immediate airway and circulatory support for the patient.     

Laboratory diagnosis of pulmonary embolism: value of increased levels of plasma D-dimer and thrombin--antithrombin III complexes

Plasma D-dimer (DD) and thrombin--antithrombin III complex (TAT) were measured with ELISAs in 99 patients investigated by 102 ventilation--perfusion lung scintigraphy because of suspected pulmonary embolism. High-probability lung scan was associated with increased DD (more than 500 ng/ml) and TAT (more than 4.1 ng/ml) levels (sensitivity of 100 and 70%, respectively). The corresponding figures of specificity were 81 and 42%. In the 56 patients with low-probability or indeterminate probability scans, 31 (55%) had DD concentrations of less than 500 ng/ml. These preliminary data suggest that a plasma DD concentration of less than 500 ng/ml might rule out the diagnosis of pulmonary embolism in suspected patients with an inconclusive lung scanning.     

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.     

Acute myocardial infarction after heart irradiation in young patients with Hodgkin's disease

Forty-seven patients younger than 40 years at the time of the diagnosis, and irradiated to the mediastinum for Hodgkin's disease at Turku University Central Hospital from 1977 to 1982, were regularly followed for 56 to 127 months after therapy. Two patients developed an acute myocardial infarction ten and 50 months after cardiac irradiation at the age of only 28 and 24 years, respectively. None of the patients died from lymphoma within five years from the diagnosis, but one of the infarctions was eventually fatal. Since acute myocardial infarction is rare in this age group, the result suggests strongly that prior cardiac irradiation is a risk factor for acute myocardial infarction. The possibility of radiation-induced myocardial infarction should be taken into account both in treatment planning and follow-up of patients with Hodgkin's disease.     

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.
