Hospital treatment -is it affordable? A structured cost analysis of vaginal deliveries and planned caesarean sections

Introduction

The analysis of cost effectiveness in hospitals is as difficult as treating the patients properly. We are yet not able to answer the simple question of what costs are caused by a certain diagnosis and its treatment during an average hospital stay.

Methods

To answer some issues of the global problem of cost effectiveness during hospitalisation, we analysed the costs and the cost structure of a normal obstetrical hospital stay during an uncomplicated vaginal delivery and a planned caesarean section. Cost data was collected and summarized from the patients file, the hospital''s computer system gathering all cost centres, known material expenses and expenses of non obstetrical medical services.

Results

For vaginal deliveries/planned caesareans we can calculate with a surplus of about 83 €/1432 €. About 45% of the summarized costs are calculated on a reliable database.

Discussion

The introduction of the DRG based clearing system in Germany has aggravated the discussion on cost effectiveness. Our meticulous work-up of expenses excluded personal precautionary costs and personnel costs of documentation because no tools are described to depict such costs. If we would add these costs to the known expenses of our study, we strongly suspect that hospital treatment of vaginal deliveries or planned caesarean sections is not cost effective.     

Response to strict and liberalized specific carbohydrate diet in pediatric Crohn’s disease

AIM: To investigate the specific carbohydrate diet(SCD) as nutritional therapy for maintenance of remission in pediatric Crohn's disease(CD). METHODS: Retrospective chart review was conducted in 11 pediatric patients with CD who initiated the SCD as therapy at time of diagnosis or flare. Two groups defined as SCD simple(diet alone, antibiotics or 5-ASA) or SCD with immunomodulators(corticosteroids and/or stable thiopurine dosing) were followed for one year and compared on disease characteristics, laboratory values and anthropometrics.RESULTS: The mean age at start of the SCD was 11.8 ± 3.0 years(range 6.6-17.6 years) with five patients starting the SCD within 5 wk of diagnosis. Three patients maintained a strict SCD diet for the study period and the mean time for liberalization was 7.7 ± 4.0 mo(range 1-12) for the remaining patients. In both groups, hematocrit, albumin and ESR values improved while on strict SCD and appeared stable after liberalization(P-value 0.006, 0.002, 0.002 respectively). The majority of children gained in weight and height percentile while on strict SCD, with small loss in weight percentile documented with liberalization. CONCLUSION: Disease control may be attainable with the SCD in pediatric CD. Further studies are needed to assess adherence, impact on mucosal healing and growth.     

A novel mutation in MED12 causes FG syndrome (Opitz–Kaveggia syndrome)

Rump P, Niessen RC, Verbruggen KT, Brouwer OF, de Raad M, Hordijk R. A novel mutation in MED12 causes FG syndrome (Opitz–Kaveggia syndrome). Opitz–Kaveggia syndrome is a rare X‐linked multiple congenital anomalies and intellectual disability disorder caused by the recurrent p.R961W mutation in the MED12 gene. Twenty‐three affected males from 10 families with this mutation in the MED12 gene have been described so far. Here we report on a new family with three affected cousins, in which we identified a novel MED12 mutation (p.G958E). This is the first demonstration that other mutations in this gene can also lead to Opitz–Kaveggia syndrome. The clinical phenotype of these three new cases is reviewed in detail and compared with the previous reported cases.     

Monitoring cerebral oxygenation during balloon occlusion with multichannel NIRS

We report on oxygenation changes noninvasively recorded by multichannel continuous-wave near infrared spectroscopy (CW-NIRS) during endovascular neuroradiologic interventions requiring temporary balloon occlusion of arteries supplying the cerebral circulation. Digital subtraction angiography (DSA) provides reference data on the site, timing, and effectiveness of the flow stagnation as well as on the amount and direction of collateral circulation. This setting allows us to relate CW-NIRS findings to brain specific perfusion changes. We focused our analysis on the transition from normal perfusion to vessel occlusion, i.e., before hypoxia becomes clinically apparent. The localization of the maximal response correlated either with the core (occlusion of the middle cerebral artery) or with the watershed areas (occlusion of the internal carotid artery) of the respective vascular territories. In one patient with clinically and angiographically confirmed insufficient collateral flow during carotid artery occlusion, the total hemoglobin concentration became significantly asymmetric, with decreased values in the ipsilateral watershed area and contralaterally increased values. Multichannel CW-NIRS monitoring might serve as an objective and early predictive marker of critical perfusion changes during interventions—to prevent hypoxic damage of the brain. It also might provide valuable human reference data on oxygenation changes as they typically occur during acute stroke.     

Stroke causes a transient imbalance of interhemispheric information flow in EEG during non-REM sleep

Objective

Large-scale connectivity, especially interhemispheric connections, plays a crucial role for recovery after stroke. Here we used methods from information theory to characterize interhemispheric information flow in wake- and sleep-EEG after cerebral ischemia.

Three-year randomized controlled trial of dipyridamole and low-dose warfarin in patients with IgA nephropathy and renal impairment

Summary: Activation of platelets and the coagulation pathway are factors which may contribute to the progression of renal disease in IgA nephropathy (IgAN). Of 21 patients with IgAN and serum creatinines between 1.6 and 3.0 mg/dL, 10 were assigned to treatment with dipyridamole and low-dose warfarin (keeping the thrombotest between 30 and 50%) and 11 to no treatment in a prospective randomized 3-year study. At entry into the trial, patients in the treatment group were younger (35 ± 6 years vs 42 ± 9 years) and had worse histological scores for tubular atrophy (1.7 ± 0.7 vs 1.1 ± 0.5) and arteriolar hyperplasia (1.4 ± 0.7 vs 0.7 ± 0.8) than those in the non-treatment group. There were no differences in serum creatinine values, creatinine clearances, urinary protein excretions, serum albumins or urinary erythrocyte counts. At the end of the trial, patients on treatment did not experience a significant increase in serum creatinine values (1.9 ± 0.3 mg/dL to 2.5 ± 1.2) or reduction in creatinine clearances (52 ± 20mL/min to 52 ± 27). Untreated patients, however, experienced a significant rise in serum creatinine values (2.1 ± 0.5 mg/dL to 3.3 ± 1.1, P < 0.01) and a fall in creatinine clearances (51 ± 26 mL/min to 31 ± 22, P = 0.06). There was no significant change in the proteinuria in either group (treatment group: 1.2 ± 1.2 g/day to 1.3 ± 1.1, non-treatment group: 1.9 ± 1.4 to 1.5 ± 1.1) and there was also no change in serum albumins and urinary erythrocyte counts. Four untreated and one treated patient developed end-stage renal failure during the course of the trial. This study suggests that treatment of patients with IgAN and renal impairment with dipyridamole and low-dose warfarin retards the deterioration of renal function, as measured by the serum creatinine and creatinine clearance.     

A prospective study of methylenetetrahydrofolate reductase and methionine synthase gene polymorphisms, and risk of colorectal adenoma

We examined the relationship between a functional polymorphism (667C-- >T, ala-->val) of the methylenetetrahydrofolate reductase gene (MTHFR) and the risk of colorectal adenomas in the prospective Nurses' Health Study. Among 257 incident polyp cases and 713 controls, the MTHFR val/val polymorphism [relative risk (RR) = 1.35, 95% confidence interval (CI) 0.84-2.17] was not significantly associated with risk of adenomas. This lack of association was observed for both small (RR = 1.36, 95% CI 0.76-2.45) and large (RR = 1.32, 95% CI 0.66-2.66) adenomas. Furthermore, there was no significant interaction between this polymorphism and consumption of either folate, methionine or alcohol. We also examined the relationship of a newly identified polymorphism (asp919gly) of the methionine synthase gene (MS) with the risk of colorectal adenomas in the same population. The MS gly/gly polymorphism was also not significantly associated with risk of colorectal adenomas (RR = 0.66, 95% CI 0.26-1.70). These results, which need to be confirmed in other studies, suggest that the MTHFR val/val polymorphism, which has been previously inversely associated with risk of colorectal cancer, plays a role only in a late stage (adenoma-- >carcinoma) of colorectal tumorigenesis, and/or may protect against malignant transformation in the subset of benign adenomas, which may progress to malignancy.      

Reduced-dose cladribine (2-CdA) plus mitoxantrone is effective in the treatment of mantle-cell and low-grade non-Hodgkin's lymphoma

Cladribine (2-chlorodeoxyadenosine) (2-CdA) has been shown to be effective in mantle-cell (MCL) and low-grade lymphomas (lgNHL). The aim of this multicentre study was to evaluate the rate and duration of remissions and to examine the toxicity of the combination of reduced-dose 2-CdA and mitoxantrone (CdM) in MCL and lgNHL as first-line therapy or for patients in their relapse. A total of 285 courses, median of five courses per patient, were administered to 62 evaluable patients (42 previously untreated, 20 relapsed) with 5 mg/m(2) 2-CdA per day given as an intermittent 2-h infusion over 3 consecutive days combined with 8 mg/m(2) mitoxantrone on days 1 and 2 for the untreated patients or 12 mg/m(2) mitoxantrone on day 1 for patients in their first relapse for a maximum of six cycles every four weeks. 32 follicular, 18 MCL, 9 lymphoplasmacytoid, 2 marginal zone and 1 unclassified low-grade B-cell lymphoma were involved in the study. 56 of the 62 patients responded to CdM resulting in an overall response rate of 90% (95% confidence interval (CI), 80-96%) with a complete remission (CR) rate of 44% (95% CI, 31-57%) and a median duration of remission of 25 months (range 6-42+). The overall survival rate at 48 months was 80%. For 42 previously untreated patients, the overall response rate was 88% (95% CI, 74-96%) with a CR rate of 38% (95% CI, 24-54%), whereas the response rate for the group of 20 previously treated patients was similar with a 95% overall response (95% CI, 75-100%) and a CR rate of 55% (95% CI, 32-77%). In MCL, CdM showed a high activity, achieving a response rate of 100% (95% CI, 81-100%) with a CR rate of 44% and a median duration of remission of 24 months (range 6-35+). Myelosuppression was the major toxicity with 23% grade 3 granulocytopenia and 50% grade 4. Thrombocytopenia was less commonly observed, with only 8% grades 3 and 4. These results demonstrate that the combination of reduced-dose 2-CdA and mitoxantrone is a highly active regimen in the treatment of low-grade lymphomas, and in particular of MCL.     

Tumor markers in dialysis-dependent renal failure. A comparison of the mucin-like carcinoma antigen, CA 15-3, CA 125, CA 19-9 and CEA antigens

The concentration of tumor markers in human sera is affected not only by malignant, but also by many benign diseases. In this regard, only few reports exist about renal insufficiency, whereas influences of different liver diseases have frequently been described. We determined the serum levels of the antigens MCA, CA 15-3, CA 125, CA 19-9, and CEA in 50 patients suffering from renal insufficiency in chronic hemodialysis, but without indication of malignant diseases. We found no difference between the serum concentrations of MCA and CA 125 as compared to the healthy control group, whereas the other antigens were more often elevated in the group of patients (CEA, 24% of patients greater than 5 ng/ml; CA 15-3, 20% of patients greater than 30 U/ml; CA 19-9, 14% of patients greater than 40 U/ml). We did not find any correlation between pathological values of markers and diseases leading to renal failure. As the increase of tumor markers could not be explained by concomitant diseases, it seems likely that the terminal renal insufficiency plays a causal role.
