Dermatomyositis associated with malignant melanoma--a marker of poor prognosis?

BACKGROUND: Dermatomyositis (DM) is an inflammatory connective tissue disorder well recognized as a paraneoplastic syndrome in adults. OBJECTIVE: The objective of this study was to assess the prognosis of DM associated with malignant melanoma (MM). PATIENTS AND METHODS: We systematically searched databases (PubMed, MEDLINE, and WEB OF SCIENCE) for articles reporting the concurrence of DM and MM. For the literature study, time of onset of DM in relation to diagnosis of MM (before, concomitant with, or after), stage of MM after restaging (according to the American Joint Committee on Cancer [AJCC] guidelines, 2001), and survival time after diagnosis of DM were recorded. Survival time studies and univariate statistical analyses were performed. Furthermore, we present our own clinical case of a patient with DM concomitantly occurring with regional lymph node metastasis of MM. RESULTS: In 5 cases DM occurred before, in 6 cases concomitantly with, and in 6 cases after progression of MM. Univariate analysis identified the AJCC stage of MM as a significant prognostic factor. Gender, age, and the time interval between onset of DM and progression of melanoma were unrelated. The 1-year actuarial survival rate was 0% for patients with DM when occurring with MM at stage IV and 60% when occurring with MM at stage III (P < .05). The estimated mean survival time was 6.6 months for patients with MM stage IV and 57 months for stage III. LIMITATIONS: The conclusions from this study are limited by the relatively small number of articles that reported the association of MM and DM. CONCLUSION: DM occurring in patients with MM at stage IV is connected with an extremely poor prognosis, whereas the few reported patients with DM and MM at stage III, including our case, have a prognosis similar to stage III patients without DM.

Left ventricular dyssynchrony predicts response and prognosis after cardiac resynchronization therapy.

OBJECTIVES: This study was designed to predict the response and prognosis after cardiac resynchronization therapy (CRT) in patients with end-stage heart failure (HF). BACKGROUND: Cardiac resynchronization therapy improves HF symptoms, exercise capacity, and left ventricular (LV) function. Because not all patients respond, preimplantation identification of responders is needed. In the present study, response to CRT was predicted by the presence of LV dyssynchrony assessed by tissue Doppler imaging. Moreover, the prognostic value of LV dyssynchrony in patients undergoing CRT was assessed. METHODS: Eighty-five patients with end-stage HF, QRS duration >120 ms, and left bundle-branch block were evaluated by tissue Doppler imaging before CRT. At baseline and six months follow-up, New York Heart Association functional class, quality of life and 6-min walking distance, LV volumes, and LV ejection fraction were determined. Events (death, hospitalization for decompensated HF) were obtained during one-year follow-up. RESULTS: Responders (74%) and nonresponders (26%) had comparable baseline characteristics, except for a larger dyssynchrony in responders (87 +/- 49 ms vs. 35 +/- 20 ms, p < 0.01). Receiver-operator characteristic curve analysis demonstrated that an optimal cutoff value of 65 ms for LV dyssynchrony yielded a sensitivity and specificity of 80% to predict clinical improvement and of 92% to predict LV reverse remodeling. Patients with dyssynchrony >/=65 ms had an excellent prognosis (6% event rate) after CRT as compared with a 50% event rate in patients with dyssynchrony <65 ms (p < 0.001). CONCLUSIONS: Patients with LV dyssynchrony >/=65 ms respond to CRT and have an excellent prognosis after CRT.

A new anatomic score for prognosis after cardiac catheterization in patients with previous bypass surgery.

OBJECTIVES: The purpose of this study was to determine the value of a new anatomic score for prognosis after diagnostic catheterization in patients with previous coronary artery bypass grafting (CABG). BACKGROUND: Previous CABG patients comprise a growing proportion of patients with coronary artery disease (CAD). Whereas prognostic scores are available to adjust for native CAD, there are no comparable scores for patients with previous CABG. METHODS: We studied 3,178 previous CABG patients (2,729 in a training set) who underwent cardiac catheterization. With a Cox model to develop relative weights in the training set, we created a graft index that adjusted native anatomy for territories with grafts free of significant (> or =75%) stenoses. Scaling the regression coefficients by the maximum coefficient created an index ranging from 0 to 100, where 100 was three-vessel CAD with no patent grafts. RESULTS: The graft index was significantly associated with all-cause death (chi-square = 121.9, p < 0.001). In combined models, the index was more strongly associated with all-cause death than either number of diseased vessels (chi-square = 68.0 and 1.7, respectively) or the Duke CAD index (chi-square = 54.3 and 9.5, respectively). In models for death using an independent validation set, the index was also associated more strongly than either native disease descriptors. In a model including other clinical variables, the graft index remained significantly associated with all-cause death (chi-square = 40.1, p < 0.001). CONCLUSIONS: For previous CABG patients, the Duke graft index was significantly more associated with prognosis than native anatomy alone and quantifies the effect of patent grafts on survival. This tool has the potential to help determine prognosis and inform the referral of post-CABG patients to repeat revascularization procedures.

In a retrospective study of chronic obstructive pulmonary disease inpatients, respiratory comorbidities were significantly associated with prognosis.

BACKGROUND AND OBJECTIVE: Comorbidities may be related to the prognosis for chronic obstructive pulmonary disease (COPD). We examined respiratory comorbidities associated with length of stay and in-hospital mortality among COPD patients. METHODS: We used the Hospital Person Oriented Information (HPOI) database of Statistics Canada for a 5-year period. Over 4 years (fiscal years 1994-1995 to 1998-1999), 143,135 records listed COPD as the most responsible diagnosis for men and 122,065 records for women aged 40 years or more, and 75,780 men and 69,539 women were admitted to hospital at least once. Logistic regression modeling was used to examine the relationships between respiratory comorbidities and hospital outcomes adjusting for covariates. RESULTS: Of the COPD patients, 10% had pneumonia-influenza and 3% had asthma as comorbid conditions. Women had a higher prevalence of asthma than men. The median length of stay at hospital was approximately 7 days, and 95% of patients were discharged alive. The odds ratio (95% confidence interval) for pneumonia-influenza in relation to in-hospital death was 3.56 (3.31, 3.83) for men and 3.29 (3.00, 3.61) for women. For comorbid asthma the corresponding odds ratios were 0.56 (0.36, 0.61) and 0.54 (0.35, 0.57), respectively. CONCLUSIONS: COPD inpatients with pneumonia-influenza had a worse prognosis and those with asthma had a better prognosis.

Persistent normalization of serum alanine aminotransferase levels improves the prognosis of type 1 autoimmune hepatitis.

BACKGROUND/AIMS: Autoimmune hepatitis shows a good response to immunosuppressive treatment, and the prognosis may be determined by the clinical course. The present study was conducted in order to analyze the factors contributing to the outcomes of patients with type 1 autoimmune hepatitis. METHODS: Eighty-four consecutive patients with type 1 autoimmune hepatitis were followed up regularly for a median follow-up period of 70.5 months (16.2-163 months). We analyzed the prognostic factors using time-fixed and time-dependent Cox proportional hazard models. The end point was progression of the disease to decompensated liver cirrhosis. RESULTS: Seventy-seven patients (92%) were treated with prednisolone during the follow-up period, and 11 patients (13%) developed decompensated liver cirrhosis. Using a time-dependent multivariate model, the starting dose of corticosteroid (dose of prednisolone <20 mg/day), relapse within 3 months after the normalization of serum alanine aminotransferase levels with initial treatment, and elevated serum alanine aminotransferase levels during the follow-up period (>40 IU/L), all showed a significant association with progression of the disease. CONCLUSIONS: The prognosis of type 1 autoimmune hepatitis on adequate immunosuppressive treatment improves when the serum alanine aminotransferase level persists at < or = 40 IU/L. Factors existing prior to medical treatment may not affect the prognosis.

The timing of primary neurosurgical repair significantly affects neurogenic bladder prognosis in children with myelomeningocele.

PURPOSE: The correlation between timing of the primary neurosurgical repair and urological prognosis in infants with open spinal dysraphism remains unknown. We investigated the impact of primary repair timing on neurogenic bladder prognosis in children with myelomeningocele. MATERIALS AND METHODS: We retrospectively reviewed the records of 401 children with myelomeningocele followed at our multidisciplinary clinic between 1996 and 2005. Among these patients 129 were included in the study based on the availability of urological followup data at age 3 years, which was chosen as an ideal point for the standardization of urological findings. Children were assigned to 1 of 2 groups-those who underwent primary neurosurgical repair within 72 hours of delivery (group 1) and those undergoing repair after 72 hours (group 2). We compared the incidence of febrile urinary tract infections, hydronephrosis, vesicoureteral reflux and secondary tethering of the spinal cord at age 3 years, as well as cystometric bladder capacity and detrusor leak point pressure between the 2 groups. RESULTS: Urological followup data at age 3 years revealed significantly increased incidence of febrile urinary tract infections, vesicoureteral reflux, hydronephrosis and secondary tethering of the spinal cord in children in group 2 compared to group 1 (chi-square, p < or =0.05 for all comparisons). Urodynamic assessment also showed a significantly lower bladder capacity and a substantially higher detrusor leak point pressure in children who received primary repair at later than 72 hours (t test, p <0.05). A subgroup analysis of group 1 comparing children who underwent repair before and after 24 hours following delivery failed to demonstrate any significant difference in terms of febrile urinary tract infections, vesicoureteral reflux, hydronephrosis and secondary tethering (chi-square, p >0.05 for all comparisons), whereas mean bladder capacity was significantly higher (t test, p <0.05) and mean detrusor leak point pressure was lower (t test, p = 0.08) in children undergoing repair within 24 hours of delivery. CONCLUSIONS: The timing of primary neurosurgical repair has a significant impact on neurogenic bladder prognosis in children with myelomeningocele. Closure of the spinal lesion on the first day of life seems to provide the best chance for favorable lower urinary tract function.

V(H)3-48 and V(H)3-53, as well as V(H)3-21, gene rearrangements define unique subgroups in CLL and are associated with biased lambda light chain restriction, homologous LCDR3 sequences and poor prognosis.

This study determined IgV(H) gene usage in 228 chronic lymphocytic leukaemia patients to investigate associations between gene usage and other biological or clinical characteristics. V(H)3-48 [N=8] and V(H)3-53 [N=4] gene rearrangements showed biased lambda light chain restriction and were predominantly found in female patients with short lymphocyte doubling time but without adverse prognosis cytogenetics. Overuse of V(L)3-21(Vlambda2-14) gene and highly homologous LCDR3 sequences were found in V(H)3-48 patients. V(H)3-21 gene usage [N=18, 7.9%] was associated with poor prognosis, overuse of V(L)3-21(Vlambda2-14) gene and highly homologous heavy- and light-chain CDR3 sequences, but was not associated with poor prognosis chromosomal aberrations.

Matrix metalloproteinase-13 expression is associated with bone marrow microinvolvement and prognosis in non-small cell lung cancer.

Our previous study demonstrated that bone marrow microinvolvement (BMM) is an epiphenomenon of tumor progression rather than a prognostic factor in non-small cell lung cancer. We hypothesize that an increase in mesenchymal transition power in epithelial tumor cells by up-regulation of the matrix metalloproteinases (MMPs) may contribute to the existence of BMM and poorer prognosis. Hereby we conducted a prospective study of BMM and MMPs expression in a cohort of 57 non-small cell lung cancer patients. Bone aspirates were examined by immunohistochemical stains. Expressions of MMPs were checked by Human MMP primer set kit (Maxim Biotech, USA). Correlations between the MMPs expression and BMM, nodal metastasis, and prognosis were examined. Cox model analysis was used to identify independent prognostic factors. Though positive BMM was identified in 38 (66.7%) of the patients, none of the clinicopathological factors, including sex, age, cell types, tumor differentiation, nodal metastasis and TNM status of the tumor, was related to BMM by the tumor cells. Up-regulation was observed in a broad spectrum of MMPs with the exception of MMP-3. However, only MMP-13 expression correlated with the existence of BMM (p=0.006). Univariate analysis revealed MMP-3, MMP-7 and MMP-13 as negative prognostic factors. Cox model analysis revealed T-status, cell differentiation, and MMP-13 expression of the tumor as independent prognostic factors. The overall 5-year survival rate of the patients was 36.8%. The existence of BMM itself did not influence the prognosis (p=0.109), however, patients with positive MMP-13 expression (N=34) had a poorer 5-year survival rate of 26.5% (p=0.025). In summary, non-small cell lung cancer cells with MMP-13 expression, despite of BMM status, tend to shed and aggregate in the bone marrow, which is subsequently reflected in a poorer survival rate.

Promoter methylation of RASSF1A, RARbeta and DAPK predict poor prognosis of patients with malignant mesothelioma.

Hypermethylation occurs frequently in neoplastic cells and affects tumorigenesis. Malignant mesothelioma is an aggressive cancer developing in the thoracic cavity and patients have a rather bad prognosis. Our goal was to determine epigenetic alterations of a series of genes and to analyse the potential correlation of such changes with overall survival. We have analysed the methylation status of the promoter region of nine genes in serum DNA of mesothelioma patients by a nested methylation-specific PCR. Modest methylation frequencies were detected for APC1A (14.3%), RASSF1A (19.5%) and DAPK (20.0%) while hypermethylation of E-cadherin (71.4%) and FHIT (78.0%) occurred at a high incidence. Intermediate values were seen for p16(INK4a) (28.2%), APC1B (32.5%), p14(ARF) (44.2%) and RARbeta (55.8%). The methylation status of none of the single genes significantly influenced prognosis. In contrast, combining RARbeta with either DAPK or RASSF1A showed a significantly shorter overall survival of those patients who had both genes methylated compared to those with only one or no epigenetic alteration (P=0.025 and 0.040, respectively). Similarly, the combination of all three genes revealed a worse prognosis for patients with double or triple methylations compared to the group which had only one or no gene methylated (P=0.028). Our results support the idea that the prognostic value of a combination of epigenetic alterations is superior to the impact of an individual gene alone on overall survival.

Birdshot chorioretinopathy: long-term manifestations and visual prognosis.

PURPOSE: To ascertain the clinical features and long-term visual prognosis of birdshot chorioretinopathy (BCR), and to identify patients at risk of visual loss. DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Fifty-five consecutive patients with HLA-A29-positive BCR who were identified in ophthalmology departments of the University Medical Center of Utrecht and The Eye Hospital Rotterdam, of whom 37 were observed for at least 5 years. INTERVENTION: A review of the medical and photographic and/or angiographic records of 55 patients with HLA-A29-positive BCR. MAIN OUTCOME MEASURES: Numerous variables were compared, including age and gender distribution, onset and course of BCR, ocular manifestations, therapeutic strategies and their outcomes, complications, systemic diseases, visual acuity (VA), and features associated with poor visual outcome. RESULTS: Loss of VA was gradual; the number of affected eyes with VA less than 20/200 increased from 9 of 108 (8%) at onset to 22 of 73 (30%) at 5 years and 19 of 49 (39%) at 10 years of follow-up. The cause of compromised VA was predominantly macular edema and macular atrophy (42 of 55 [76% of cases]). We found strong associations between the VA at onset and visual outcome after 5 and 10 years (P = 0.005 and P = 0.006, respectively). Mean VA at the 5-year follow-up was significantly lower if macular leakage was observed on angiography (P<0.001). No differences in annual loss of VA were observed between patients treated by standard therapeutic modalities and untreated patients. CONCLUSION: The visual prognosis of BCR in a spectrum of uveitis is poor, and the recommended therapeutic regimens have had no effect on long-term visual prognosis. New treatment strategies are needed for this blinding disorder.

Expression of vascular endothelial growth factor and prognosis of oral squamous cell carcinoma.

The correlation between expression of vascular endothelial growth factor (VEGF) and prognosis for oral squamous cell carcinoma was investigated. Tissue samples of oral squamous cell carcinoma were obtained from 63 patients. Of these patients, 11 had stage I, 17 had stage II, 9 had stage III, and 26 had stage IV tumours. Immunohistochemical expression of VEGF was quantitatively determined by computer-assisted image analysis. The value of VEGF expression was significantly higher for the patients with poor prognosis than for those with good prognosis (P=0.0423). Regarding regional lymph node metastasis, VEGF showed no significant difference between metastasis positive and negative patients. Expression of VEGF may thus be a prognostic marker for oral squamous cell carcinoma.

Prognosis of hypercalcemia in aerodigestive tract cancers: study of 136 recent cases.

Recent data issuing the prognostic impact of hypercalcemia on outcome of aerodigestive tract cancers are spare. To assess the prognosis and the survival of head and neck cancer patients with hypercalcemia, we reviewed 136 recent successive cases, including also oesophageal and lung cancers. Data were collected from a retrospective database (July 2002-January 2004). Hypercalcemia was defined by calcemia level above 2.55 mmol/l. Univariate analysis for prognosis was performed with Mann-Whitney test (continuous variables) and Odd Ratio with 95% confidence interval (categorical variables). The primary locations were : oropharynx and oral cavity (79, 58%), hypopharynx (13, 9.5%), larynx (10, 7.3%), oesophagus (17, 12.5%) and lung (17, 12.5%). There were 23 females and 123 males, with a median age of 53 (18-86). The incidence of bone metastasis was low: 20/136, 14.5%. At cancer diagnosis, 32 hypercalcemia were observed. With a median follow-up of 88 days (2-553), we observed 98 deaths (overall mortality=72%). The median overall survival was 35 days (2-553+). The pejorative prognostic factors were: male gender (OR=2.64 CI 95% 1.07-6.82), age inferior to 50 (OR=2.67 CI 95% 1.23-5.8), presence of distant metastasis (OR=4.45 CI 95% 1.8-11.01), elevation of alkaline phosphatases (OR=7 CI 95% 2.73-17.9) and need of hospitalization for intravenous hydratation (OR=5.11 CI 95% 1.99-13.17). We observed 39 recurrences of hypercalcemia. The predictive factors for recurrence of hypercalcemia were: age superior to 50 (OR=4.61 CI 95% 2.02-10.52), male gender (OR=38.22 CI 95% 12.2-89), calcemia level superior to 2.7 mmol/l (OR=3.08 CI 95% 1.42-6.64) and absence of diphosphonates (bisphosphonates: OR=2.16 CI 95% 1.01-4.63). Despite use of diphosphonates (infusions of pamidronate), hypercalcemia is associated with very poor prognosis. Tumour location and level of calcemia had no prognostic value.

Dysplasia/neoplasia surveillance in oral lichen planus patients: a description of clinical criteria adopted at a single centre and their impact on prognosis.

The concept of dysplasia/neoplasia surveillance has been applied to long-standing conditions associated with an increased risk of cancer. Although still controversial, periodic direct clinical examination as well as endoscopic techniques are currently performed in patients with inflammatory bowel diseases, Barrett's esophagus, and melanocytic skin lesions in order to detect and treat dysplastic or early malignant changes and therefore improve the patients' prognosis. It is not known if patients with oral lichen planus (OLP), a chronic inflammatory condition associated with an increased risk of cancer development, might benefit from such surveillance as well, nor how this should be performed. Here we present the clinical criteria we have adopted over a 12-year period to detect early malignant transformation of OLP, and report on their impact on the management and prognosis of patients. Overall data from 45 patients affected by 117 neoplastic events arising from OLP have been evaluated. Our dysplasia/neoplasia surveillance has led us to diagnose most episodes (94.9%; n.: 111) of OLP malignant transformation in early intraepithelial and microinvasive phases, namely stage 0 and I oral cancers (T(is) N0M0 or T1N0M0). The 5-year survival rate, where applicable, has been 96.7%. Advanced stage oral cancers have been diagnosed in six patients, three of whom have died. We suggest that the application of strict and rigorous clinical criteria in dysplasia/neoplasia surveillance could help clinicians to detect and treat early OLP malignant transformation and therefore improve long-term survival rates. Nevertheless, a small subgroup of patients has been shown not to benefit from such surveillance and to be characterized by a rapid development of advanced-stage oral carcinomas, with consequent poor prognosis.

Repeat assessment improves the prediction of prognosis in patients with low back pain in primary care.

Low back pain is considered to fluctuate over time, and related prognostic factors may behave similarly, therefore classification of prognosis may be affected by timing of assessment. We aimed to investigate the implications of timing of assessment of prognosis in low back pain. In a prospective cohort of primary care low back pain consulters aged 30-59 years, 359 returned questionnaires at baseline, one-month and one-year. The stability of selected prognostic indicators between baseline and one-month later was assessed, and relative risks for their association with outcome (individually and in combination) were calculated. Reported absence of most outcome indicators was stable between baseline and one-month. However, among people reporting presence of indicators at baseline, only around half still reported them a month later. There were no important differences between the prognostic strength of indicators measured at baseline or one-month. People reporting presence of indicators at either point had significantly higher risk of poor outcome than people not reporting the indicator at all. Presence of the indicators at both time points was associated with even higher risk; people with persistent high pain intensity had 15 times the risk of a poor outcome (relative risk 15.1; 95% confidence interval 6.7-33.8) compared with people not reporting high pain at either point. Combining information on prognostic indicators from two time points provides better classification of low back pain patients' eventual outcome than a single measurement alone. This increased accuracy in predicting prognosis is relevant to both clinical and research practice.

Radiotherapy is effective in patients with glioblastoma multiforme with a limited prognosis and in patients above 70 years of age: a retrospective single institution analysis.

BACKGROUND AND PURPOSE: To evaluate the efficacy of radiotherapy in patients with glioblastoma multiforme (GBM) with a limited prognosis and in patients older than 70 years. PATIENTS AND METHODS: Retrospective analysis of 202 patients with GBM treated between 1990 and 2000 in a single institution. Patients (including patients >or=70 years) were assigned to RPA groups and their survival was compared with RTOG data. RESULTS: Median survival was 8.0 months for the total group and 13.9, 10.6, 3.8, 2.1 months for RPA group III (n=17), IV (n=87), V (n=60) and VI (n=38), respectively. Median survival for patients >or=70 years was 3.6 vs. 8.1 months for 50--70 years and 11.0 months for <50. In each separate RPA group, patients >or=70 years had a similar survival compared to patients of 50--70 years. Irradiated patients (66%) survived significantly longer than non-irradiated patients: 10.6 vs. 1.9 months (P<0.0001). In RPA group V the median survival for irradiated patients was 9.4 vs. 2.1 months for non-irradiated patients. In a multivariate analysis, RT remained the only prognostic factor for survival (HR 8.9, P<0.001). CONCLUSIONS: Prognosis for patients above 70 years of age is not different from younger patients, when analyzed for separate RPA groups. For patients with a poor prognosis (i.e. RPA group V), radiotherapy improves survival significantly.

Simple scoring system for the prediction of the prognosis of severe acute pancreatitis.

BACKGROUND: In severe acute pancreatitis (SAP), it is important clinically to predict the prognosis at the time of admission. Most scoring systems for severity of acute pancreatitis consist of multiple factors and are complicated. This investigation aimed to propose a simple scoring system for the prediction of the prognosis of SAP. METHODS: Prognostic factors were evaluated by receiver operator characteristic curve analyses and multivariate analysis from data that were obtained on admission of 137 patients with SAP. A simple scoring system with 3 most useful factors was made, and its usefulness was investigated in comparison with conventional scoring systems. RESULTS: Three prognostic factors were selected: serum blood urea nitrogen > or = 25 mg/dL, serum lactate dehydrogenase > or = 900 IU/L, and contrast-enhanced computed tomography finding with pancreatic necrosis. On admission, 137 patients were classified from 0 to 3 by the number of positive items (simple prognostic score [SPS]). Mortality rates for patients whose SPS was 0, 1, 2, and 3 were 2% (1/42 patients), 18% (7/40 patients), 48% (12/25 patients), and 67% (20/30 patients), respectively. Furthermore, when usefulness of SPS was compared with conventional scoring systems, the area under the curve by receiver operator characteristic curve analyses in SPS was 0.83; the Ranson score was 0.83; the Japanese severity score was 0.83; the Acute Physiology and Chronic Health Evaluation II score was 0.81, and the Glasgow score was 0.75. After onset, SPS kept almost same levels from day 2 to day 6, and a significant difference was observed between survivors and nonsurvivors from day 1 to day 6. CONCLUSION: This scoring system that comprised 3 items is simple, is feasible for the prediction of prognosis and conventional scoring systems, and is useful for the selection of the extremely severe patients with SAP on admission.

The key to improving prognosis for aneurysmal subarachnoid hemorrhage remains in the pre-hospitalization period.

BACKGROUND: Despite advances in neurosurgical management, aneurismal subarachnoid hemorrhage (aSAH) still has high mortality and morbidity. This study aimed to clarify how delaying hospital admission after aSAH contributes to worse prognosis even today and to find the possibility for an improvement of its prognosis by early admission. METHODS: Four hundred twenty-one consecutive patients are the basis for this study. Cause of delay was classified into 5 categories: patient delay (PD), doctor delay (DD), transportation delay (TD), no delay (ND) (within 2 hours of onset), and others. Condition of each patient was assessed at time of onset and admission using H&K. The relationships between cause of delay and worsening of Hunt and Kosnik grading (H&K) were examined. RESULTS: The median delay time was 1.7 days. Only 41% of patients visited our institution without delay. Admission delay, especially PD and DD, exhibited a significant correlation to worsening of H&K. In addition to nondirect admission, misdiagnosis or delayed diagnosis contributed significantly to worsening of H&K. Incidence of DD has declined in recent years, whereas that of PD has increased. Consequently, no change in total number of delays was found. CONCLUSIONS: There remains much room for an improvement of prognosis for aSAH by early admission. We need to fully realize this reality and to directly face this problem.

Symptomatic venous thromboembolism in acute leukemia. Incidence, risk factors, and impact on prognosis.

The association between malignant disorders and occurrence of venous thromboembolism is well established. Patients with cancer and venous thromboembolism have adverse prognosis. No systematic study on the incidence and prognostic impact of venous thromboembolism in acute leukemia has been performed as yet. We retrospectively evaluated the incidence of symptomatic venous thromboembolism before chemotherapy in 719 patients (371 males and 348 females, median age of 57.4 years), diagnosed with acute leukemia [534 with acute myelogenous leukemia, 185 with acute lymphoblastic leukemia]. Furthermore, the relationship of venous thromboembolism to clinical and laboratory parameters and its impact on prognosis was assessed. Fifteen patients (2.09%) had venous thromboembolism (objectively confirmed in 13 patients) in close temporal relationship to the onset of acute leukemia. The incidence of venous thromboembolism was the same in acute myelogenous and lymphoblastic leukemia. In five patients, pulmonary embolism was documented. Venous thromboembolism occurred in all subtypes of acute leukemia, but was most common in promyelocytic leukemia. All but one patient were treated with anticoagulants. No patient died from treatment-related bleedings or venous thromboembolism. Overall, survival, disease-free survival, and remission duration did not differ between the patient groups with and without venous thromboembolism. In contrast to solid tumors, venous thromboembolism before or at diagnosis of acute leukemia is not associated with poor prognosis.
