COSTING A HOSPITAL SERVICE PRODUCT: MARGINAL Vs ABSORPTION COSTING

Costing a service product is a challenging but important tool for cost control. Different methods used for costing may provide varying costs and the choice of the method used becomes important. Use of absorption costing and marginal costing method and treatment of labour cost as variable and fixed cost provided different results in the present study of the cost of below knee patellar tendon bearing prosthesis. The study shows that marginal costing should also be done along with the absorption cost as it provides better indicator for cost control.Key Words: Absorption Costing, Cost Control, Marginal Costing, Prosthesis     

TOTAL QUALITY MANAGEMENT - THE NEW PARADIGM IN HEALTH CARE MANAGEMENT

Hospitals are by nature complex organisations and the complexity is compounded in service hospitals with perceived notion of service deficiencies. Quality has emerged as a major issue in health care sector and TQM has been accepted as a major long-term strategic initiative towards continuously improving quality of health care. Key concepts of TQM start with top management leadership with emphasis on process and customer focus. Implementation of TQM in service hospitals will require Quality Management awareness, training and framework development as well as development of customer awareness. TQM has been widely applied in clinical field with successful outcome. TQM is not a short-term solution, it has to be understood and practised as a long-term strategic commitment.Key Words: Quality in Health Care, Total Quality Management(TQM)     

BEHAVIOURAL AND EMOTIONAL PROBLEMS IN SCHOOL GOING ADOLESCENTS

Background

Adolescents are highly vulnerable to psychiatric disorders. This study aimed to explore the prevalence and patterns of behavioural and emotional problems in adolescents. It was also aimed to explore associations between socioenvironmental stressors and maladaptive outcomes.

Method

A school based cross-sectional study was conducted between January and July 2008. A stratified random sampling was done. 1150 adolescents in 12 to 18 year age group in grades 7 to 12 in 10 co-educational schools (government run and private) were the subjects of the study. Behavioural and emotional problems were assessed using Youth Self-Report (2001) questionnaire. Family stressors were assessed using a pre-tested 23 item questionnaire. Univariate and multivariate analysis were performed. Multiple logistic regression analysis was also done.

Results

Prevalence of behavioural and emotional problems in adolescents was found to be 30%, with girls exceeding boys in all age groups. Internalizing syndrome was the most common (28.6%) psychiatric problem. On stepwise regression analysis, a perceived lack of emotional proximity to mother had the highest odds (3.489) followed by addiction in father (2.642) and marital discord in parents (1.402). Type of school, type of family, socioeconomic status, relationship with father, mother&s employment and educational status were not found to be significantly associated

Conclusion

An alarming number of our adolescents suffer from emotional and behavioural problems which have their roots in the family environment. These data suggest urgency in establishing a school based mental health service.     

Investigation of DNA damage response and apoptotic gene methylation pattern in sporadic breast tumors using high throughput quantitative DNA methylation analysis technology

Background-  

Sporadic breast cancer like many other cancers is proposed to be a manifestation of abnormal genetic and epigenetic changes. For the past decade our laboratory has identified genes involved in DNA damage response (DDR), apoptosis and immunesurvelliance pathways to influence sporadic breast cancer risk in north Indian population. Further to enhance our knowledge at the epigenetic level, we performed DNA methylation study involving 17 gene promoter regions belonging to DNA damage response (DDR) and death receptor apoptotic pathway in 162 paired normal and cancerous breast tissues from 81 sporadic breast cancer patients, using a high throughput quantitative DNA methylation analysis technology.     

Conventional MRI at presentation does not predict clinical response to radiation therapy in children with diffuse pontine glioma

BACKGROUND： Diffuse pontine glioma is a pediatric brain tumor with a median survival time of 1 year and few long-term survivors. Conventional MRI has not been shown to predict overall survival. With this dismal prognosis, clinical improvement after radiation therapy might be a more relevant issue. OBJECTIVE： To determine whether initial imaging would predict clinical response. MATERIALS AND METHODS： We performed a retrospective review of children with diffuse pontine glioma treated at The Children＇s Hospital, Denver, and the University of Colorado-Denver from 1995 to 2008. The 30 children were divided into two groups based on acute clinical response to radiation therapy.     

Mediastinal histoplasmosis granuloma: evaluation with CT

Mediastinal granuloma secondary to histoplasmosis was described in three patients. Computed tomographic scans in each patient demonstrated a large, low-attenuation mediastinal mass crossed by enhancing septae. Other granulomatous diseases may produce similar abnormalities. The differential diagnosis of such lesions was discussed.     

Normalization of cellular zinc levels in patients with Down's syndrome does not always correct low thymulin levels

Retrospective analysis of five Down's syndrome (DS) patients who presented with recurrent infection revealed that all had initial low thymulin levels. Three patients had low cellular zinc levels that normalized after zinc replacement. Contrary to previous studies, thymulin levels were persistently low in four of five DS patients despite maintaining or achieving normal cellular zinc levels. A primary thymic epithelial defect may be responsible for the persistent thymulin deficiency in DS patients.     

Malignant neoplasms following bone marrow transplantation

We undertook an analysis of 2,150 recipients of bone marrow transplant (BMT) at the University of Minnesota to determine the incidence of post- BMT malignant neoplasms (MNs). Fifty-one patients developed 53 MNs, compared with 4.3 expected from general population rates (standardized incidence ratio [SIR], 11.6, 95% confidence interval [CI], 8.2-14.5). These included 22 occurrences of B-cell lymphoproliferative disorder (BLPD), 17 solid nonhematopoietic tumors, 10 myelodysplastic syndromes (MDS), 1 acute myelogenous leukemia (AML), 2 non-Hodgkin's lymphoma (NHL), and 1 Hodgkin's disease (HD). The estimated actuarial incidence of any post-BMT malignancy was 9.9% +/- 2.3% at 13 years posttransplant. The cumulative probability of BLPD plateaued at 1.6% +/- 0.3% by 4 years from transplant and factors independently associated with increased risk included in vitro T-cell depletion of marrow (relative risk (RR) = 11.9, P < .001), HLA mismatch (RR = 8.9, P < .001), use of antithymocyte globulin (ATG) for graft versus host disease (GVHD) prophylaxis (RR = 5.9, P < .001) or in the preparative regimen (RR = 3.1, P = .03) and primary immunodeficiency (RR = 2.5, P = .06). The cumulative probability of developing solid malignancy was 5.6% +/- 2.2% at 13 years from BMT. Malignant melanomas were the most common (SIR, 10.3, 95% CI 1.9 to 25.4). The actuarial incidence of MDS/AML plateaued at 2.1% +/- 0.8% at 9 years and was seen most often in older patients receiving autologous peripheral blood stem cells for HD or NHL. These data document that BMT recipients are at an increased risk of later malignancy, which may add significant morbidity and mortality to the transplant process. Methods for screening and identification of individuals at increased risk need to be addressed in future studies.     

Estrogen modulates the recruitment of myelopoietic cell progenitors in rat through a stromal cell-independent mechanism involving apoptosis

Loss of ovarian function leads to a significant increase in the number of bone-resorbing osteoclasts. Estrogen replacement is known to manifest bone protective effects in the treatment of postmenopausal osteoporosis. In the present study, we used ovariectomized rats to examine the effects of estrogen loss at the osteoclast progenitor colony forming unit-granulocyte macrophage (CFU-GM) level. A significant increase in CFU-GM number was observed as early as 7 days following ovariectomy, and correlated directly with an increase in the number of osteoclast-like cells generated in marrow cultures. The increase in CFU-GM following ovariectomy was abrogated in animals that received estrogen treatment in vivo. A similar suppressive effect was observed on CFU-GM number when ovariectomized rat marrow was treated with estrogen in vitro. This effect was blocked in the presence of the estrogen antihormone ICI 164,384. Thus, the data suggest the possibility that estrogen exerts a direct effect on osteoclast progenitors, and does so through the estrogen receptor-mediated mechanism. Ovariectomy also led to an increase in the early hematopoietic stem/progenitor cell population (Thy 1.1+ cells) as determined by FLOW cytometry methods. Morphological changes as well as terminal deoxynucleotidyl transferase assays revealed that estrogen treatment negated growth factor-induced proliferation of these early progenitors by promoting apoptosis. The cellular effects of estrogen in vitro together with the immunocytochemical detection of the estrogen receptor in these cells, strongly support the contention that in addition to osteoclast progenitors such as CFU-GM, earlier hematopoietic progenitors are also unique cellular targets for estrogen action.     

CLINICAL APPLICATION OF FLOW CYTOMETRY IN LIVE RELATED DONOR RENAL TRANSPLANTATION

To monitor the activity of the humoral component in graft dysfunction following renal transplantation using live related donors, flowcytometric cross-match procedure was adopted. Antidonor antibodies were detected in the sera of both pre- and post-transplant patients using conventional serological cytotoxicity cross-match and flowcytometric cross-match assays. In the 52 pretransplant samples no significant differences were observed in flowcytometric and cytotoxicity tests except in 2 secondary transplant cases which were negative by cytotoxicity test. However, in post-transplant samples, floweytometry was found to be a more objective and useful test than cytotoxicity testing in distinguishing 6 out of 7 mild acute-graft-rejection episodes. Both tests were found to be negative in alt 5 cases of cyclosporin-A nephrotoxicity, 7 cases of acute tubular necrosis and 10 out of 11 cases of chronic rejection.KEY WORDS: Flowcytometry, Cross-match, Graft dysfunction, Kidney transplantation
