Cell surface antigen -- a study in bladder tumours.

Thirty bladder tumours of various stages and grades were examined for the presence of A.B.O. (H) cell surface antigen using specific red cell adherence (SCRA) technique. Ten patients with stage A disease and low grade tumour (grade I) retained the antigens, whereas all patients with high stage disease (B,C,D) and high grade tumours showed absence of antigen. When these data were correlated with recurrence pattern and metastasis or invasion rate, patients who did not show the antigen at the initial visit developed metastases and had poor prognoses. The patient who had expressed the antigen by positive SCRA had fewer recurrences and a longer tumour-free interval. Hence if SCRA is done in all bladder tumours at the initial visit and at subsequent follow-up, it can be used as a biological marker.

Primary carcinoma of female urethra: review of 20 cases.

Twenty patients of primary urethral carcinoma in females are presented. Age group affected was between 40 and 60 years. Vague symptoms in early stage delayed the diagnosis in most patients. Surgery is the treatment of choice for meatal or anterior urethral lesions while combined Radiotherapy and surgery has been suggested as treatment for entire urethral lesions. In the present series 33% three years and 21% five years survivals were noted.

Lingual thyroid: a review of 12 cases.

Twelve patients with lingual thyroid are reviewed. Two of these patients had a follicular carcinoma in the ectopic gland and both are well 5 and 16 years after treatment. The diagnosis is essentially clinical but confirmation may be made with a thyroid scan. Six patients were treated conservatively with thyroxine with good results. Six patients were treated by surgical excision, 2 undergoing autotransplantation of the excised gland into the anterior abdominal wall.

The impact of cisplat based chemotherapy on advanced ovarian cancer.

Cisplatinum based chemotherapy has become the standard treatment for ovarian cancers due to its proved superiority over non-cisplat based regimes. However, the therapeutic impact of cisplat based regimes compared to cheaper non-cisplatinum based regimes is questionable when multiple variables such as residual disease, histologic type, grade are introduced. This report is a study of 110 Stage III ovarian cancer patients from 1985-89, with cisplat (n = 69) and non cisplat (n = 41) based chemotherapy. The results of both regimes with reference to the multiple variable factors are presented. We conclude that cisplat based regimes appear to be superior to non-cisplat based regimes except probably in poorly differentiated ovarian tumors where the results were similar with either regimen.

Mobile radiography CQI: an inter-national study.

Mobile or bedside radiography has been and is a staple diagnostic and follow-up tool used readily by the many medical disciplines, such as cardiology, surgery, orthopedics, pediatrics, neonatology, etc. Ironically, in the past a student or the least qualified technologist was sent to perform the bedside exam. Moreover, it was almost expected that poor but acceptable film quality would result or that repeat films were almost always to be taken. Inefficiency with respect to quality of exam, the time the exam takes, or film repeats can be costly. The price of inefficiency is the cost involved in doing things incorrectly or not in the most efficient manner, i.e., incurring inefficiencies instead of operating in an ideal manner. The purpose of this study was to compare the total cost of inefficiently organized, scheduled and performed mobile radiography at three large teaching hospitals in various locations and of diverse patient loads, as a means of determining how best to increase utilization and performance. The study was performed at the 489-bed New England Deaconess Hospital (NEDH), the 644-bed Sentara Norfolk General Hospital (SNGH), and the 1500-bed Rheinische Westfalische Technische Hochschule (RWTH) in Aachen, Germany. Similar standardized study methods were utilized at all three institutions where extended observation of mobile utilization, areas of inefficiency, time wasted per episode and number of episodes per time period were determined. Data were loggedin at three standardized time periods, summated, and then multiplied by technologist hourly pay rate. This sum was extrapolated over 52 weeks to give the total annual cost of inefficiently organized mobile radiography. For NEDH the cost of total inefficiency was $75,453, for SNGH $49,586, while for RWTH it was $9,519. Eighteen areas of inefficiency were identified and grouped, such as lack of spatial cohesiveness and lack of communication leading to film duplication, etc. While inefficiencies in the delivery of hospital based health care are well known, this study attempts to quantify and determine a dollar value for each process found as inefficient. Key inefficiencies were found to be common at large hospitals no matter whether in the United States or Europe. These impairments are responsible for a disproportionate share of overall inefficiency, and their elimination (achievable by simple solutions) would result in drastic cost reductions (ranging from 40-75% at the institutions studied). Thus this study is important in view of spiralling costs, as it is a key component of total quality management (TQM) in radiology and a continuous quality improvement (CQI) tool for mobile radiology specifically.
