Women and cancer

Cancer will be diagnosed in more than a half a million women this year. Prognosis and curability are associated with the stage of the cancer at diagnosis. If cancer is detected at an early stage, more than 75% of women can expect long-term survival or cure for the most common cancers, excluding lung. Promoting health behaviors that reduce risk and recommending screening tests are critical activities for the practitioner that may affect survival rates and quality of life of women with cancer diagnoses. Risk factors, incidence, presenting symptoms, staging, treatment and 5-year survival rates associated with 12 major cancer sites in women are presented. Diagnosis and survival for minority populations are reviewed, highlighting the need to improve cancer screening and detection for this group of women.     

Corticosteroid prescribing in rheumatoid arthritis and psoriatic arthritis

Embryos from certain mouse strains are arrested at the 2-cell stage in cell culture ('2-cell block'), whereas those from other strains develop to the blastocyst stage under the same conditions. It was previously shown that blocking embryos can be rescued in culture by aggregation with an excess of 2-cell stages of a non-blocking strain such as CBA x C57BL/6 F2. Here we have employed a LacZ transgene in a blocking strain (NMRI) to follow the fate of rescued blastomeres up to the blastocyst stage. We found that rescued blastomeres can participate in both inner cell mass and trophoblast formation, thus completely overcoming the 2-cell block.     

Syndromes and arthritis

There are many questions and no clear answers raised by these children. These syndromes, however, seem to be biologic experiments of nature and present unique opportunities to study the various elements involved in the pathogenesis of arthritis. Pediatric rheumatologists are in a unique position to study these syndromes.     

Diet and arthritis

Choice of diet is one way in which an individual can influence his/her own health, and it is to be expected that patients will seek their physician's expert opinion regarding dietary matters. Respect for the legitimacy of these enquiries and balanced informed discussion, which includes general advice for a prudent diet, as well as disease-specific recommendations when indicated, can be the key to a productive relationship between patients and physician. The issue of dietary advice has an impact on the management of most forms of arthritis including osteoarthritis (obesity/energy balance), gout (dietary purines, energy balance, alcohol, fluid intake) and rheumatoid arthritis (n-3 fatty acids). Food hypersensitivity appears to be a rare cause of polyarthritis, and elimination diets and fasting have little or no place in routine practice. Strategies under investigation include oral tolerization, the utility of which remains to be established.     

AP-1 and NF-kappaB regulation in rheumatoid arthritis and murine collagen-induced arthritis

Mandibular distraction was performed on 14 children, between September 1991 and December 1997. Their average age was 6.9 years, ranging from 1.5 to 13.5 years. All patients had severe hypoplastic mandibles with retromandibulism. Seven of the children (50%) had respiratory distress due to obstruction of the upper airway before distraction. This resolved in every case. Five patients underwent unilateral and nine bilateral distraction. A total of 23 distractors were used, 15 were applied extraorally and 8 endorally. The average latency time after operation was 2.8 days, but for the past 2 years, distraction was started beginning with the operation. The distraction was increased twice daily for an average of 5.5 weeks, by 0.4 or 0.5 mm each time, depending on the distractor. Computed tomography and ultrasound were used to follow the ossification process in the distraction gap and to measure the lengthening achieved. Subsequent retention time averaged 2.4 weeks. The mandibles were elongated by up to 18 mm (average 9.3 mm) and the respiratory distress symptoms resolved in all patients. Several minor complications which are reported occurred. Six patients were followed up for periods between 3 and 7 years. During this time further growth of the distracted mandibles was recorded.     

Noninfectious canine arthritis: rheumatoid arthritis

Chronic unremitting, generally symmetric, erosive polyarthritis was studied in 8 dogs. The disease had clinical, serologic, radiographic, and pathologic changes similar to those of rheumatoid arthritis of man. The condition occurred mainly in smaller breeds of dogs, with time of onset from 8 months to 8 years of age, Characteristic radiographic changes were seen in the joints several weeks to several months after the appearance of the initial lameness. Synovial fluid contained an increased number of neutrophils, and synovial fluid and synovial tissues were sterile for anaerobic and aerobic bacteria, mycoplasma, chlamydia, and viruses. Corticosteroids were therapeutically ineffective in all of the cases; however, corticosteroids, cyclophosphamide, and azathioprine were effective when used in combination in several dogs.     

Pregnancy and rheumatoid arthritis

Amelioration of rheumatoid arthritis (RA) occurs in about three quarters of pregnancies. Most women who improve experience initial relief in the first trimester. RA almost invariably recurs within 3 to 4 months of delivery. The effect of pregnancy upon the risk of first developing RA is similar in some respects but also differs from that observed in women with established disease. Analogous to women with established disease, the chance of a woman first developing RA is significantly reduced during pregnancy but increased in the first year post partum; thereafter risk is decreased. There is no indication of any adverse effects of RA on pregnancy outcome. Although limited, some medications can be used during pregnancy and during lactation without jeopardizing the well-being of the fetus.     

Women and power in nursing

Power is inherent in all relationships and is subject to social and political amendment. In addition social relationships can be and are dynamic, flexible, variable and may provide unlimited possibilities for influencing the course of events in the workplace. Because of such potential, an element of competitiveness amongst leaders (and thus nurse managers) for the retention of their power base is created. Since the potential for power struggles is a realistic possibility the author contends that nurse managers need to acquaint themselves with political game playing techniques and ways of enhancing their social rank on an institution wide basis. This could be effected by concerted efforts to act in relation to others and by equipping themselves with more than basic preparation in administration and management. Nurses should use their individual and collective power, influence and authority to ensure that the nursing profession may prosper and grow. Contrary to the view that women are the weaker sex, numerically they dominate the nursing profession in South Africa. They should therefore regard the reshaping of their future role and status as a responsibility, a privilege and a challenge to the power inherent in them.     

Women and injuries--factors influencing recovery

This study focuses on female patients of working age, hospitalized due to moderate, mostly orthopaedic injuries. The aim was to highlight the medical and non-medical factors affecting outcome. Two groups of women, those who 12 months after the injury reported disability within at least three out of five possible areas (work, family, household, social life and leisure-time; n = 34), were compared with women reporting disability within two areas or less (n = 59). Four factors were predictive of outcome according to the multivariate analysis: injury severity as measured by the Abbreviated Injury Scale (AIS), self-perceived injury-related mental and physical health measured by the Visual Analogue Scale (VAS) during hospitalization and a history of three or more previous injuries requiring medical care. Sociodemographic background factors did not affect the outcome. By integrating information from AIS and VAS with the number of previous injuries, three quarters of the women were correctly classified; i.e., it was possible to detect a majority of those reporting a poorer outcome one year after the injury already during hospitalization. Simple screening instruments like these seem to be useful in the early detection of vulnerable patients. This study further suggests that more attention should be paid to non-medical factors, the importance of which may have been underestimated regarding a poorer outcome among female patients hospitalized due to injuries. Thus, psychosocial support should not only be offered to patients with major trauma or an obvious psychiatric disorder, but to all injured patients and should be considered as an integral part of medical care.
