The aim was to elucidate if, by strictly applying the Adaptive Process Triage (ADAPT) scale, the interrater agreement increased among the participating registered nurses (RNs) than when triaging according to the older scale, which allowed subjective interpretations of signs and symptoms. Nineteen patient scenarios were triaged in 2006 by 45 RNs usi...

Emergency department triage is a prerequisite for the rapid identification of critically ill patients and for allocation of the correct acuity level which is pivotal for medical safety. The patient's first encounter with a medical professional in the emergency department is often with the triage nurse. To identify patient experience of the triage e...

To evaluate known and suggested prognostic markers, especially insulin-like growth factor type 1 receptor (IGF-1R), in highly malignant soft tissue sarcomas (STS). A cohort of 101 patients with primary STS of high malignancy grade was studied with respect to development of metastasis, local recurrence, and survival during a minimum of 5 years follo...

In this study, a panel of 39 primary malignant fibrous histiocytomas (MFH) of high malignancy grade were characterised for chromosomal alterations. The results were then evaluated in relation to the survival and the occurrence of recurrent disease during follow-up for an average period of 63 months. Chromosomal alterations detected by comparative g...

In this study 65 primary malignant fibrous histiocytomas (MFH) of high malignancy grade were characterized by immunohistochemistry for their expression of proteins reflecting or promoting tumor growth. The results were evaluated in relation to the disease-free survival and the occurrence of metastases alone or in combination with local recurrences...

The incidence of pancreatic cancer has fallen during the last ten years in Sweden. Early signs and symptoms of the disease are still undiscovered and when diagnosis is made the disease is incurable in most patients. Transabdominal ultrasonography is the first-line imaging test followed by spiral computed tomography (CT) and magnetic resonance imagi...

Carcinoma invasion and metastasis in general involve multiple steps including dynamic changes in the composition and structure of extracellular matrix proteins and cell surface receptors. In the present study, the usually highly invasive carcinoma of the pancreas was investigated regarding the expression of various extracellular matrix proteins and...

Purpose: Extracellular matrix metalloproteinase inducer (EMMPRIN) has been shown to stimulate fibroblasts to production of matrix metalloproteinases (MMPs). MMPs comprise a family of proteolytic enzymes implicated in the degradation of extracellular matrix which has been proposed to be one of the essential steps in tumor invasion and metastases. In...

In specimens obtained from resected pancreata, the intratumoral microvessel density (IMD), the proliferation rate of the neoplastic parenchymal cells, and their p53 protein expression were assessed. The sources of errors were great in the measurements of the IMD. This statement can be illustrated by the finding that when the IMD was calculated by m...

Morphologic verification of malignancy is usually a prerequisite before initiating nonsurgical therapy for pancreatic carcinoma. Fine-needle biopsy has been widely used, but the method has also been criticized because of inadequate sampling material and the risk of intra-abdominal seeding. Cytologic material from 334 patients with suspected pancrea...

Formalin-fixed paraffin-embedded material from 57 patients in whom curative resection of pancreatic carcinoma had been attempted was analysed by an immunohistochemical procedure to estimate proliferation and p53 protein expression. Using the monoclonal antibody (MAb) MIB-1, which recognizes a Ki-67 epitope, the proliferating cell index (PCI, percen...

The introduction of combined modality treatment has only marginally affected the prognosis in nonresectable pancreatic carcinoma. Evaluation of easily accessible prognostic variables could be of clinical importance when selecting patients for proper therapy. DNA ploidy and morphometric variables were chosen as prognostic markers and assessed on cyt...

MR imaging of an intussuscepted sigmoid cancer misinterpreted as a rectal carcinoma is described. High-resolution technique with pelvic-phased array coils and fast spin-echo was used. The diagnosis is discussed in relation to the MR findings.

The nuclear DNA content was assessed by image cytometry on cytologic specimens obtained with fine-needle aspiration biopsy in 96 patients with pancreatic duct carcinoma. Twenty-two of these patients had pancreaticoduodenal resection. According to DNA analysis there were 27 (28%) diploid, 17 (18%) tetraploid, and 52 (54%) aneuploid tumors. The corre...

Morphometric analysis whereby size and form of cellular nuclei are transformed into quantities has previously been shown to be a valuable adjunct to the histopathologic differential diagnosis between chronic pancreatitis and pancreatic carcinoma. The present study aims to assess the clinical value of morphometry performed on cytologic material from...

The laparoscopic operating technique is being applied increasingly to a variety of intra-abdominal operations. Intra-abdominal gas insufflation, i.e. pneumoperitoneum (PP), is then used to allow surgical access. The haemodynamic effects of PP in combination with different body positions have not been fully examined. Eleven patients without signs of...

An obstacle to the outflow from the bile duct not only increases bile duct pressure but also facilitates the formation of primary bile duct stones. The bile duct pressure, an indicator of the balance between bile inflow and outflow, was studied postoperatively under similar conditions in 123 patients, who had been operated on for bile duct stones....

Serum expression of the cancer-associated antigens CA 19-9 and CA 50 and their relation to Lewis blood cell status were studied in 26 patients with pancreatic duct carcinoma and 26 patients with pancreatitis. The discriminating capacity between benign and malignant disease was high for both tumor markers. The correspondence between serum levels of...

In a phase I study endoscopic removal of pancreatic duct stones and protein plugs was attempted in five patients suffering from chronic pancreatitis with severe chronic pain. The pancreatic duct contents could be extracted after successful sphincterotomy in three patients. Clearance of the pancreatic duct was followed by complete or partial relief...

Serum levels of the tumour antigens CA 19-9 and CA-50 and their relation to the extent of the disease were studied in 97 patients with carcinoma of the pancreas. Of 13 patients with normal serum concentrations of CA 19-9, 11 (84.6%) had irresectable disease, whereas 87.5% of the patients with resectable disease expressed antigen levels above cut-of...

The aim of the present study was to analyse the survival rate in a group of breast cancers detected in the intervals between screening examinations in relation to clinically detected cancers in a non-screened population. All interval and control cancers were recruited from a randomized controlled mammography screening trial in Stockholm. The overal...

Combined morphological and cytochemical malignancy grading in addition to tumor stage was applied to assess the malignant potential of so-called interval carcinomas from the Stockholm randomized mammography screening study. Only interval carcinomas surfacing within two years from screening were included. Fifty-four percent of the tumors were in sta...

Non-palpable breast cancers detected by mammography in women participating in the ongoing screening project at Södersjukhuset, Stockholm, Sweden, were classified by morphological and cytochemical malignancy grading. The women's age ranged between 40 and 64 years, and the clinical course was followed for a minimum of 5 years after primary treatment....

The predictive value of nuclear DNA content in mammary carcinoma is still under debate in spite of several reports indicating a relationship between DNA ploidy and prognosis. The impact of differences in methodology on the evaluation of DNA data is discussed, and a recent study demonstrating DNA ploidy as a statistically significant prognostic vari...

Correlated flow-cytometric (FCM) and microspectrophotometric (MSP) techniques were applied to investigating whether intratumoral variations in the DNA distribution patterns of 21 primary mammary adenocarcinomas can occur. Although neoplastic cell populations with both diploid and tetraploid (i.e., euploid) distribution patterns could be found in va...

Iodinated epidermal growth factor was used to identify its specific receptor in 32 human colorectal carcinomas. The receptor was found in 25% of the tumors with values between 6.9 - 104.0 fmoles/mg DNA. Receptors for estrogen and progesterone were detected in 45 and 25% of the tumors respectively. No correlation was observed between short term surv...

Sixty-six non-palpable, invasive mammary adenocarcinomas from the Stockholm mammography screening project were studied with respect to histopathology. In 53 of these tumors estrogen receptor (ER) content was estimated and in 30 of them also the DNA distribution pattern. The tumors were predominantly of low or intermediate histological malignancy gr...

The prognostic value of nuclear DNA distribution pattern in relation to tumor size, axillary lymph node status, and estrogen receptor (ER) content was studied in 464 patients with primary, operable mammary adenocarcinoma. The median follow-up time was 3 1/2 years. Slide cytophotometric DNA analysis was performed on morphologically identified Feulge...

The use of quantitative DNA analysis in human tumor material has increased markedly during the last years. Considering that benign tumors in general exhibit an euploid DNA distribution pattern, while malignant tumors are predominantly aneuploid, DNA measurements have been utilized as a complement to cytological or histopathological diagnosis in cas...

Tumors of 89 women, aged 75 or above, that were operated on for primary mammary carcinoma were analyzed with regard to histologic type and differentiation, estrogen receptor (ER) content, and nuclear DNA distribution pattern. The majority of the tumors were invasive ductal carcinomas but a relatively high frequency of papillary and colloid carcinom...

The relationship between mammographic appearance of microcalcifications and tumor stage, malignancy grade, estrogen receptor (ER) content and nuclear DNA pattern was studied in 92 mammary carcinomas. The results indicate that no complementary prognostic guidance can be obtained from the radiographic appearance of a tumor apart from a high probabili...

Nuclear DNA content was studied in cytologic preparations obtained from 50 patients aged 35 or less with primary mammary carcinoma. As many as 90% of the tumors were aneuploid, i.e., exhibited DNA profile types III and IV. The cytologic diagnosis was confirmed by histologic examination in 46 patients. The majority of these tumors, 83%, were invasiv...

Forty-two so-called interval cancers of the breast were studied. The mammograms were reviewed and the tumors were classified as 14 'unrecognized', 9 'observer error', 1 'technical error' and 18 'true' interval cancers. By using a scoring system based upon histologic differentiation, axillary nodal status, estrogen receptor level, and nuclear DNA co...
