Socio-economic burden of permanent incisor replantation on children and parents

Abstract – This study describes the socio‐economic burden and attitudes of children and their parents following replantation of avulsed incisors. Records of 80 patients with 99 avulsion injuries treated in a teaching hospital clinic from 1988 to 1999 were reviewed. Mean age at time of injury was 10.6 years (range = 6.6–17.7 years). Complete records for a minimum of 1 year were obtained for 43 patients with 60 replanted incisors. Mean treatment procedures provided during the first year included 5.5 diagnostic periapical radiographs, 1.9 occlusal radiographs, 1.3 pulpectomies, and 2.7 pulp medicament applications. The mean estimated treatment cost and direct time (dentist) for first‐year post‐trauma management was $1465 CAD and 7.2 h, respectively. Treatment costs were significantly higher during the first year post‐trauma for patients who had their incisors extracted (P = 0.04), but there was no significant difference in direct treatment time between the two groups (P = 0.19). Twenty‐one patient–parent pairs were surveyed for a number of qualitative factors. Ninety per cent of patients and 86% of parents reported that school and work time was lost. Even after having gone through the painful experience of replantation, the demands of recall, and in some cases, extraction, the majority of patients (67%) and parents (81%) stated that they would have still made the same (replantation) decision. Patient and parent responses were not statistically different (P = 0.453). Almost half the parents stated they would be willing to pay over $2000 CAD to save an incisor. Patients rated retention of an incisor as significantly more important than infraocclusion. This is the first study to quantify the treatment burden of replantation of avulsion injuries exclusively in the pediatric population. This study describes the socio‐economic burden and responsibilities of patient/parent and dentist and their role in informed consent.     

Binucleated and multinucleated forms of plasma cells in synovia from patients with rheumatoid arthritis

A morphological examination of synovial tissue from 25 patients with rheumatoid arthritis revealed that binucleated or multinucleated plasma cells were present in all samples and absent in synovia obtained from 16 control patients. Plasma cells containing two, three of four nuclei constitutet a mean 3% of the total plasma cell population. They were aways found amongst plasma cell infiltrates and in close association with small blood vessels. Ultrastructural analysis found no evidence of cellular membranes separating the individual nuclei in binucleated or multinucleated plasma cells, suggesting that the cells did not arise from fusion. Some of these plasma cells had a diameter approaching 100 μm, and many were in intimate contact with macrophages. The demonstration of a few cells with mitotic figures within the infiltrates suggests that the maintenance of plasma cell numbers in rheumatoid synovium may depend, in part, upon their local proliferation.

Primary lymphoma of prostate: transrectal ultrasonic appearance

In the case presented, primary lymphoma of the prostate was diagnosed by ultrasonically guided transrectal biopsy. Primary lymphoma of the prostate should be included in the differential diagnosis of a hypoechoic lesion found on ultrasonic evaluation of the prostate in a young adult.     

School-Based Cardiovascular Health Promotion: The Child and Adolescent Trial for Cardiovascular Health (CATCH)

The Child and Adolescent Trial for Cardiovascular Health (CATCH) is a multisite intervention research study that builds on significant progress made in school health education research in the 1980s. The study has three phases: Phase I deals with study design, intervention, and measurement development, Phase II involves the main trial in 96 schools in four states, and Phase III focuses on analysis. The intervention program targets third-fifth grade students and focuses on multiple cardiovascular health behaviors, including eating habits, physical activity, and cigarette smoking. Classroom curricula, school environmental change, and family involvement programs are developed for each grade level and behavioral focus. This paper describes Phase II of CATCH with a rationale for cardiovascular health promotion with youth. The process of change that appears to be necessary for school-based health promotion and that will be tested in CATCH are presented as a framework to guide these efforts.     

Drugs and the bone marrow

Some drugs have a predictable suppressive effect upon the bone marrow and are used in the treatment of malignant disease. Others are unpredictable and may cause unanticipated side effects to bone marrow during the treatment of non-malignant pathologies. In this article, bone marrow maturation is discussed and both the defined and potential effects of drugs upon the bone marrow are considered.     

Costs and benefits of routine follow-up after curative treatment for endometrial cancer

OBJECTIVE: To examine the costs of routine outpatient follow-up after curative treatment of endometrial cancer, and to determine whether this leads to early detection of recurrence or survival. The impact of specific disease characteristics on survival is examined. DESIGN: Retrospective chart review, and calculation of costs. SETTING: Ottawa Regional Cancer Centre-Civic Division (ORCC-C). PATIENTS: All 432 patients referred to the ORCC-C with endometrial cancer between 1982 and 1991 who received treatment with curative intent and who continued with routine follow-up. RESULTS: Cancer recurred in 50 patients (11.57%). There was no statistically significant difference in overall survival between patients with symptomatic and asymptomatic recurrences, or between those with recurrences detected during routine follow-up visits or in the interval between routine visits. Of 4830 Papanicolaou (Pap) smears performed routinely, cancer was detected in 6 cases. The mean cost of the routine follow-up procedures for each patient with a recurrence was $19,200. CONCLUSION: Intensive follow-up of women with endometrial cancer does not result in improved survival. A prospective randomized study is warranted to evaluate other potential benefits of follow-up, such as improved quality of life or decreased morbidity. There is no economic or clinical justification for the routine use of the Pap smear in the follow-up of patients with endometrial cancer. The potential benefits of routine follow-up in endometrial cancer and other types of cancer with favourable prognoses warrant critical evaluation.
