Prognosis after liver transplantation predicted by preoperative MELD score.

The model for end-stage liver disease (MELD) has been an excellent predictor of 3-month mortality among cirrhotic patients awaiting orthotopic liver transplantation (OLT). The aim of this study was to evaluate whether the preoperative MELD score predicts short-term prognosis after OLT. We enrolled 98 adult liver transplant patients performed at our center from January 2001 to December 2002. In univariate analysis of risk factors for death within 3 and 6 months after liver transplantation, serum total bilirubin, creatinine, MELD score, hyponatremia with ascites, Child-Turcotte-Pugh (CTP) score were statistically significant parameters (P < .05). By logistic regression, none of the risk factors were subjected to multivariate analysis showed statistical significance. The odds ratios of the MELD score, hyponatremia with ascites, CTP score within 3 months were 0.997, 1.151, and 0.726 with 95% confidence intervals of [0.899, 1.105], [0.102, 12.959], and [0.389, 1.352], respectively. The odds ratio of MELD score, hyponatremia with ascites, CTP score within 6 months were 0.996, 0.914, and 0.764, with 95% confidence intervals of [0.901, 1.102], [0.089, 9.369], and [0.417, 1.401], respectively. Although MELD score has been a good predictor of short-term prognosis before OLT, MELD did not show an influence on the short-term prognosis after liver transplantation in this study.

Usefulness of histologic homogeneity estimation of muscle-invasive urinary bladder cancer in an individual prognosis: a mapping study.

OBJECTIVES: To examine the histologic homogeneity of muscle-invasive urothelial cell carcinoma of the bladder, with conventional and nonconventional (eg, squamous, glandular, or variants) differentiation, to assess its influence on prognosis. METHODS: With organ mapping, we investigated 38 cystectomy specimens. Each entire bladder was cut into 88 slices according to an identical topographic scheme. From all the bladder slices, 1231 slices that included tumor were chosen for the histologic study. We examined the diagnostic significance, extension, and number of histologic differentiation types. RESULTS: The extension of nonconventional differentiation, with any proportion of histologic type, had an unfavorable impact on survival time. The number of nonconventional differentiation types increases in the presence of a sarcomatoid, an undifferentiated, a nested, or a micropapillary pattern. The increased number of differentiation types had an unfavorable influence on survival time. Patients with a more than 80% classic urothelial cell carcinoma pattern had a favorable prognosis, which increased further with increasing percentages of this differentiation type. CONCLUSIONS: Muscle-invasive urinary bladder cancers are not a homogenous group of tumors. Our results suggest that a precise assessment of the extension and number of histological differentiation types may be an individual prognostic factor. Conventional differentiation with at least 80% extension seems to be prognostically favorable. Nonconventional differentiation, especially with greater extension and a greater number of types, could imply a worse prognosis.

Cryptogenic localization-related epilepsy with childhood onset: The problem of definition and prognosis.

BACKGROUND: Up to one-third of children with epilepsy are diagnosed with cryptogenic localization-related epilepsy (CLRE). CLRE is a large nonspecific category within the ILAE classification. For this population no unequivocal prognosis exists. METHODS: Twenty-five articles describing aspects of CLRE were included in this review. RESULTS: As a result of the progress in epilepsy research, as well as more advanced investigation in individual cases, the population with CLRE constantly changes. Also, disagreement on interpretation of the classification has resulted in striking differences between the populations described. High remission rates are reported, but relapse occurs frequently, leaving the long-term prognosis unforeseeable. This is reflected in academic and psychosocial prognosis, which is described to be problematic in CLRE specifically. Possible prognostic factors of CLRE in children have been identified: age at onset, seizure semiology, seizure frequency, intractability, interictal epileptiform activity on EEG, and premorbid IQ. These factors are explored to define subgroups within the CLRE population. DISCUSSION: Prospective studies on well-defined CLRE cohorts are needed to identify factors that distinguish various prognostic subgroups. Specific attention should be focused on course of the epilepsy, scholastic achievement, and psychosocial outcome.

Gamma mode of infiltration associated with poor prognosis in malignant teratoma of the ovary: A case report.

BACKGROUND: Although mature cystic teratoma is the most common tumor of the ovary, squamous cell carcinoma arising from a mature teratoma is a rare event. Prognosis depends on clinical stage, grade, and recently described mode of tumor infiltration. CASE: This case involves a 52-year-old woman with stage II squamous cell carcinoma arising in a mature cystic teratoma of the left ovary. Final pathology demonstrated poorly differentiated squamous cell carcinoma with gamma mode of tumor infiltration. The patient completed adjuvant chemotherapy and subsequently died of progressive disease. CONCLUSION: Squamous cell carcinoma arising from a benign cystic teratoma is a rare event. Studies have shown stage, grade, and mode of infiltration to be predictors of recurrence and prognosis. This case supports the growing evidence linking the mode of tumor infiltration with overall prognosis of survival.

Comparison of the prognosis after early versus late recurrent nonfatal myocardial infarction. DAVIT Study Group. Danish Verapamil Infarction Trial.

BACKGROUND: Recurrent nonfatal myocardial infarction (RNMI) is the most significant risk factor for later outcome after an index infarction. However, little is known about the prognosis after RNMIs that occur beyond the first year after the index infarction. METHODS AND RESULTS: In 3867 nonselected patients <76 years old with an acute myocardial infarction, we studied the rate of and prognosis after a first RNMI, depending on the year of its occurrence after the index infarction. Mortality rate was estimated by the method of Kaplan-Meier, and the differences were evaluated by means of the Tarone-Ware test. Four hundred ninety-three (13.6%) patients had a first RNMI in the first, 151 (5.4%) in the second, 105 (4.2%) in the third, and 71 (3.8%) in the fourth year after the index infarction (groups 1 through 4). One-year mortality rate after RNMI was 23.7% in the first group, 24.1% in the second group, 17.5% in the third group, and 22.8 in the fourth group. When all the groups were compared with each other, no significant difference was found between the mortality rates (p = 0.12) or standardized mortality rates. CONCLUSIONS: Late RNMIs have almost the same grave prognosis as do early RNMIs.

Prognosis of congestive heart failure and predictors of mortality.

The interaction of physiologic variables that appear to be predictive of prognosis in patients with severe congestive heart failure was examined in a series of 139 patients referred to a heart failure service. Left ventricular ejection fraction, peak oxygen consumption during a progressive maximal exercise test and resting plasma norepinephrine concentration were identified as the strongest univariate predictors of prognosis. Examination of their interaction was accomplished by stratifying each variable into quartiles and then pooling quartiles for bivariate analysis. The data demonstrate that ejection fraction has the most profound effect on survival calculated from maximal oxygen consumption and norepinephrine concentration, but that each of the variables provides additional independent prognostic information when added to survival estimated from any of the other variables. Therefore, ventricular function, exercise tolerance and sympathetic nervous system activation appear to provide independent insight into the prognosis of patients with heart failure.

What does it mean to improve prognosis of patients with coronary artery disease?

When improvement in prognosis of patients with coronary artery disease is the goal, the physician must be knowledgeable about the patient-related factors and the fact that therapies influence prognosis in such patients. Further, the clinician must be very specific in choice of therapeutic agents directed toward improvement of prognosis, and this process must include prescriptions of appropriate formulation and dosage.

Long-term prognosis in women with normal dobutamine stress echocardiography.

Although the long-term prognosis for patients with a normal dobutamine stress echocardiographic result is good, most studies have focused on men. We assessed the long-term cardiac prognosis for women by reviewing the cases of 100 women who underwent dobutamine stress echocardiography for suspected coronary artery disease and found that women with a normal result have an excellent long-term cardiac prognosis.

Prognostic implications of ambulatory myocardial ischemia and arrhythmias and relations to ischemia on exercise in chronic stable angina pectoris (the Angina Prognosis Study in Stockholm [APSIS]).

The prognostic significance of ambulatory ischemia, alone and in relation to ischemia during exercise was assessed in 686 patients (475 men) with chronic stable angina pectoris taking part in the Angina Prognosis Study In Stockholm (APSIS), who had 24-hour ambulatory electrocardiographic registrations and exercise tests at baseline (n = 678) and after 1 month (n = 607) of double-blind treatment with metoprolol or verapamil. Ambulatory electrocardiograms were analyzed for ventricular premature complexes and ST-segment depression. During a median follow-up of 40 months, 29 patients died of cardiovascular (CV) causes, 27 had a nonfatal myocardial infarction, and 89 underwent revascularization. Patients with CV death had more episodes (median 5 vs. 1; p<0.01) and longer median duration (24 vs. 3 minutes; p<0.01) of ST-segment depression than patients without events. For those who had undergone revascularization, the duration was also longer (12 vs. 3 minutes; p<0.05). In a multivariate Cox model including sex, history of previous myocardial infarction, hypertension, and diabetes, the duration of ST-segment depression independently predicted CV death. When exercise testing was included, ambulatory ischemia carried additional prognostic information only among patients with ST-segment depression > or =2 mm during exercise. When the treatment given and treatment effects on ambulatory ischemia were added to the Cox model, no significant impact on prognosis was found. Ventricular premature complexes carried no prognostic information. Thus, in patients with stable angina pectoris, ischemia during ambulatory monitoring showed independent prognostic importance regarding CV death. Ambulatory electrocardiographic monitoring and exercise testing provide complementary information, but only among patients with marked ischemia during exercise. Treatment reduced ambulatory ischemia, but the short-term treatment effects did not significantly influence prognosis.

Significance of preoperative elevation of serum C-reactive protein as an indicator for prognosis in colorectal cancer.

BACKGROUND: C-reactive protein (CRP) is a product synthesized in hepatocytes and has been reported to be upregulated by such proinflammatory cytokines as interleukin-1, interleukin-6, and tumor necrosis factor. The significance of a preoperative serum elevation in CRP as a predictive indicator for the malignant potential and prognosis in colorectal cancer has not been elucidated. METHOD: One hundred and twenty consecutive patients with colorectal cancer, whose local lesions were resected in our department, were selected. Any patients with inflammatory diseases such as infection or collagen diseases were excluded from the current study. The preoperative serum CRP level was measured, and the relationship between the serum elevation of CRP and both the clinicopathologic factors and prognosis of the patients was investigated. RESULTS: The incidences of liver metastases, peritonitis carcinomatosa, histopathologic lymph nodes metastasis, and intravascular invasion in patients with a preoperatively elevated serum CRP level were significantly more frequent than in those with a negative serum protein level. The survival rates of the patients without a preoperative elevation of the serum CRP proved to be significantly more favorable than that of the patients with such an elevation (P <0.001). CONCLUSIONS: A preoperative serum elevation of CRP was thus found to be an indicator of the malignant potential of the tumor as well as a predictor of the prognosis of patients with colorectal cancer.

[Prognosis of organic mitral regurgitation and implications for surgical indications].

The term organic Mitral Regurgitation (MR) relates to MR secondary to anatomic alteration of the valvular or subvalvular mitral apparatus and refers to rheumatic MR and degenerative MR, i.e. mitral valve prolapse, which has become in the past 20 years the 1st cause of severe MR leading to surgery in western countries. Recent publications on the prognosis of patients with MR secondary to flail leaflet, showed that these patients incur excess mortality rates as compared to expected and that ten years after diagnosis, 90% of those will either be dead or operated on for severe symptoms. On the other hand, analysis of postoperative prognosis showed that the best results of surgical correction were observed in asymptomatic patients with normal pre-operative left ventricular function. The prognosis of these patients was then similar to that expected if a valvular repair was performed, making of mitral repair the hinge point of early surgical strategies.

[Cephalic pancreaticoduodenectomy for adenocarcinoma of the head of the pancreas: does pylorus preservation change morbidity and prognosis?].

STUDY AIM: To evaluate the influence of a pylorus-preserving on the morbidity and prognosis of patient with pancreaticoduodenectomy for adenocarcinoma of pancreas. PATIENTS AND METHODS: Between 1985 and 1999, 183 patients were operated on for pancreatic adenocarcinoma. Among them, 63 patients (40 men, mean age 63 years, range 41-77 years) had curative resection and were included in this retrospective study. They were classified according to the type of resection. In the group I, the procedure included a pylorus-preserving pancreaticoduodenectomy (n = 35). In the group II, the procedure included polar inferior gastrectomy (n = 28). The prognosis was compared. Parameters for comparison were rate of local recurrence, rate of metastatic evolution and duration of survival. RESULTS: The operative length and mortality rate (group I: 0%, group II: 3%), general (p = 0.37) and specific morbidity (p = 0.30), frequency of delayed gastric emptying were similar in the 2 groups (group I: 20%, group II: 35%, p = 0.88). The duration of naso-gastic aspiration was shorter in the group I (6 days vs 8, p = 0.01). The prognosis was the same in the 2 groups (metastasis: group I: 39%, group II: 56%, p = 0.12, local recurrence: group I: 58%, group II: 43%, p = 0.09, mean survival: group I: 18 months, group II: 19 months, p = 0.77). CONCLUSION: These results suggest that pylorus preserving pancreatoduodenectomy could be performed for patients with adenocarcinoma of the head of the pancreas and does not compromise survival.

Thymic carcinoma: involvement of great vessels indicates poor prognosis.

BACKGROUND: Thymic carcinoma is a rare, indolent, and invasive cancer. This study investigated the treatment results of thymic carcinoma and clinical prognostic factors. METHODS: From June 1988 to January 2002, 38 patients were enrolled in this study with the diagnosis of thymic carcinoma in the Cheng-Kung University Hospital based on Rosai's and Muller-Hermelink's classification. Clinical and pathologic data were retrospectively reviewed. Survival analysis was performed using the Kaplan-Meier, log rank, and Wilcoxon tests. Statistical significance was defined as p < 0.05. RESULTS: Pathology revealed 14 poorly differentiated, 6 moderately differentiated, and 8 well-differentiated squamous cell carcinomas; 8 lymphoepithelioma-like carcinomas; and 2 other carcinomas. Pathologic staging using the Masaoka system included 6 stage II, 23 stage III, and 9 stage IV patients. Six biopsies, five debulkings, and 27 complete resections were performed. All patients were followed from 15 months to 10 years 9 months, with an average of 53.8 months. Median survival time was 81 months, and median recurrence time was 52 months. Eighteen patients are still alive, and 7 are alive with disease. Well-differentiated squamous cell carcinoma had better prognosis than other carcinomas (p = 0.022). Complete resection significantly increased survival rate (p < 0.001). Tumor invasion of the superior vena cava, pulmonary vessels, or aorta were significant predictors for poor prognosis (p = 0.016, 0.002, and 0.002, respectively). CONCLUSIONS: Only patients with thymic carcinoma who underwent complete resection had long-term survival. Prognosis of thymic carcinoma seemed mainly dependent on tumor invasion of the great vessels.

Survival and prognosis after pneumonectomy for lung cancer in the elderly.

BACKGROUND: The number of elderly patients with lung cancer is increasing. This study was undertaken to assess the validity of pneumonectomy for the treatment of lung cancer in this patient group. METHODS: Twenty-seven patients 70 years old or older (elderly group) and 95 patients younger than 70 years (younger group) who underwent pneumonectomy between January 1985 and March 1996 formed the study group. In the elderly group, 22 patients had squamous cell carcinoma, 2 had adenocarcinoma and 3, small cell carcinoma; 1 patient was in postoperative stage I, 4 patients were in stage II, 14 in stage IIIA, 5 in stage IIIB, and 3 in stage IV of the disease. The only significant differences in patient characteristics between the two groups were the percentage of patients undergoing right pneumonectomy and the percentage of patients receiving chemotherapy or radiotherapy within 3 months before or after operation or both times. RESULTS: The prognosis for the elderly group was comparable to that of the younger group for all stages of the disease; the overall 5-year survival rate was 30.5% for the younger group and 11.5% for the elderly group. However, operation-associated mortality was significantly higher in the elderly group (22.2% versus 3.2%; p < 0.005). The prognosis was better for patients with a centrally located tumor than a peripheral tumor in both groups [13.5% versus 2.0% in the elderly group and 46.7% versus 5.2% (p < 0.01) in the younger group] and significantly better for patients having a left pneumonectomy than a right pneumonectomy in the younger group (46.7% versus 5.2%; p < 0.01) but not in the elderly group (13.7% versus 22.2%). Adjuvant treatment did not have any beneficial effect on the prognosis in either group. CONCLUSIONS: Pneumonectomy for lung cancer in elderly patients appears to be justified because the outcome in our study was comparable with that for the younger patients. However, it should be performed only in carefully selected patients because of the increased operative risk.

Understanding prognosis to improve rehabilitation: the example of lateral elbow pain.

OBJECTIVE: A systematic overview of evidence aimed at determining the clinical course of lateral elbow pain and prognostic factors that affect elbow pain duration and outcomes. DATA SOURCES: Online bibliographic database searches from 1983 to 1994; information requests from selected authors and bibliography screenings. STUDY SELECTION: One author reviewed 424 articles; 40 met the following eligibility criteria: any study with primary data on soft tissue injuries specific to the elbow which referred to prognosis or reported use of any outcome measure. DATA ABSTRACTION: Strength of evidence grade based on clinical epidemiological validity assessment. Criteria included in the validity assessment included case definition, patient selection, follow-up, outcome, prognostic factors, and analysis. All eligible studies were independently assessed by two investigators. DATA SYNTHESIS: Four studies (10%) were judged to provide moderate strength of evidence; no studies were graded as providing strong evidence on prognosis. All four moderate-quality studies were clinical trials of short duration. One study indicated that site of lesion and prior occurrence may be predictive of poorer outcome in patients with lateral epicondylitis. CONCLUSION: The majority of studies on lateral elbow pain were limited by methodological weaknesses in selection and definition of the study population, length of follow-up, and analysis of prognostic factors. Estimates of duration were only available from weaker studies with longer follow-up times; significant subject heterogeneity in the weaker studies prevented a determination of usual clinical course. More methodologically rigorous research on prognosis could assist clinicians in patient care and evaluation of interventions.

Visual prognosis for symptomatic retinal arterial macroaneurysm.

PURPOSE: To study the visual prognosis in eyes with symptomatic retinal arterial macroaneurysm (RAM). METHODS: Medical records were retrospectively reviewed for 62 patients (65 eyes) with symptomatic RAM. RESULTS: The median visual acuity at presentation was 0.4 for eyes with vitreous hemorrhage (n=6), 0.01 for eyes with premacular hemorrhage (n=9), 0.1 for eyes with submacular hemorrhage without premacular hemorrhage (n=16), 0.02 for eyes with submacular hemorrhage with premacular hemorrhage (n=16), and 0.3 for eyes with macular edema (n=18). The median value of the final visual acuity was 0.6 for vitreous hemorrhage, 0.7 for premacular hemorrhage, 0.1 for submacular hemorrhage without premacular hemorrhage, 0.1 for submacular hemorrhage with premacular hemorrhage, and 0.5 for macular edema. CONCLUSIONS: The visual prognosis for eyes with symptomatic RAM depends on the macular pathology. Eyes with vitreous hemorrhage or premacular hemorrhage recover good vision, while the vision in those with submacular hemorrhage with or without premacular hemorrhage generally remains poor. New interventions including submacular surgery or pneumatic displacement of submacular hematoma should be evaluated in a future study in terms of visual prognosis for these eyes.

Epidemiological features and visual prognosis of Behçet's disease.

PURPOSE: Retrospective evaluation of epidemiological features and visual prognosis of patients with Behçet's disease (BD) who visited the University of Tokyo Hospital between 1974 and 1993. OBSERVATIONS: During the survey period, more than 100 new patients with BD visited the uveitis clinic in each 5-year period. The number of new patients decreased in the most recent 5-year period from 1989 to 1993. Although BD has always been more prevalent in men, the percentage of women has increased to 24.7% (19/77) in the most recent 5-year survey period. The percentage of patients who initially manifested ocular symptoms in their third or fourth decade was more than 70%. The proportion of the incomplete type of BD gradually had increased to 62.3% (48/77) by 1993. Among the extraocular major symptoms, oral aphtha and skin lesions have been frequent and genital ulcer has become less frequent in the last 20 years. The patients whose visual acuity was better than 0.4 at the first visit in the 1984-1993 period had a significantly better visual prognosis than the patients in the previous 10-year period. The main drug therapy consisted of colchicine and cyclophosphamide in the earlier 10-year period, and of colchicine and ciclosporin in the later 10-year period. CONCLUSIONS: Behçet's disease is still one of the most frequently encountered types of endogenous uveitis. There have been some changes in the epidemiological features of the patients with BD over the past 20 years. The introduction of ciclosporin in 1985 is probably responsible for the improvement of the visual prognosis in BD patients.

Correction of congenital diaphragmatic hernia in utero IX: fetuses with poor prognosis (liver herniation and low lung-to-head ratio) can be saved by fetoscopic temporary tracheal occlusion.

BACKGROUND/PURPOSE: Fetuses with congenital diaphragmatic hernia (CDH) who have a "poor prognosis" with postnatal treatment now can be identified on the basis of liver herniation, early diagnosis (before 25 weeks' gestation) and a low lung-to-head ratio (LHR). Because complete in utero repair proved unsuccessful for this group, the strategy of temporary tracheal occlusion was developed to gradually enlarge the hypoplastic fetal lung. The purpose of this study is to compare the outcome of patients in the poor-prognosis group treated by one of three methods: (1) standard postnatal care, (2) fetal tracheal occlusion via open hysterotomy, and (3) the recently developed video-fetoscopic (Fetendo) technique of tracheal occlusion without hysterotomy. METHODS: In the past 3 years, 34 of 86 fetuses with an isolated left CDH met criteria for the poor-prognosis group. Thirteen families chose postnatal treatment at an extracorporeal membrane oxygenation (ECMO) center, 13 underwent open fetal tracheal occlusion, and eight underwent fetoscopic tracheal occlusion. RESULTS: The survival rate was 38% in the group treated by standard postnatal therapy, 15% in the open tracheal occlusion group, and 75% in the Fetendo group. There were less postoperative pulmonary complications noted in mothers who underwent the Fetendo procedure versus the open tracheal occlusion. All but one Fetendo clip patient had a striking physiological response demonstrated by sonographic enlargement of the small left lung that was documented postnatally by plain radiographs and its subjective appearance during repair of the CDH. In contrast, only 5 of the 13 open tracheal occlusion patients demonstrated lung growth. CONCLUSION: Fetuses with a left CDH who have liver herniation and a low LHR are at high risk of neonatal demise and appear to benefit from temporary tracheal occlusion when performed fetoscopically, but not when performed by open fetal surgery.
