Relationship between CA 15-3 serum levels and disease extent in predicting overall survival of breast cancer patients with newly diagnosed metastatic disease

Soft tissue sarcomas (STS) of the hand are rare in children and adolescents. From 1965 through 1995, 18 children with STS of the hand were treated at our institution. Rhabdomyosarcoma (RMS) was diagnosed in 11 patients; alveolar histological results predominated (7 of 11 cases). Seven patients presented with metastatic disease and died 4 to 23 months (median, 9 months) from diagnosis; their surgical treatment comprised above-elbow amputation (n = 1), local excision (n = 1), and biopsy (n = 5). For the four patients who presented with localized RMS, surgery consisted of wide local excision (n = 1), local excision (n = 2), or ray amputation (n = 1). With an average follow-up of 5.5 years (range, 4 months to 18 years), 3 of the 11 patients diagnosed with RMS still survive (27%). The remaining seven patients presented with nonrhabdomyosarcomatous soft tissue sarcoma (NRSTS); the most common histological variants were epithelioid and malignant fibrous histiocytoma (two cases each). Surgical treatment for these patients comprised ray amputation (n = 3), wide local excision (n = 3), excisional biopsy (n = 1), and regional lymph node dissection (n = 3). One patient received adjuvant multiagent chemotherapy; three patients received supplemental radiotherapy. Six of the seven (85%) patients are alive with no evidence of disease at an average follow-up of 4.7 years (range, 6 months to 12 years).     

Dialysate CA125 levels in stable peritoneal dialysis patients

Single-stage surgery is an acceptable option in the modern management of many acute colonic conditions. Anastomosing unprepared colon is a major concern. A technique is described that allows on-the-table colonic lavage to be performed without contamination of the abdominal cavity.     

Clinical utility of clozapine in 16 patients with neurological disease

Patients who develop psychosis or agitated behavior secondary to neurological disorders present a therapeutic dilemma. The authors review clinical efficacy and side effect profiles of clozapine in a cohort of 16 patients with various neurobehavioral disorders. One-third showed a marked decrease in symptoms while on clozapine. However, one-quarter developed an acute confusional state; of these, all had diffuse slowing on their baseline EEG prior to starting the drug.     

Prognostic value in predicting overall survival of two mucinous markers: CA 15-3 and CA 125 in breast cancer patients at first relapse of disease

The role of circulating tumour markers in providing prognostic information has been scarcely studied. We evaluated the prognostic significance of two mucinous markers: CA 15-3 and CA 125 in 115 breast cancer patients at first recurrence of disease. At diagnosis of advanced disease bone involvement was found in 64 patients, lung in 57, skin lymph nodes in 21, liver in 20, and brain in 5. Patients were recruited and treated in the same institution with conventional chemo- or endocrine therapy. The follow-up ranged from 3 to 54+ months (median 35). Serum samples were drawn at first recurrence of disease before the start of any endocrine and/or chemotherapy. Patients with CA 15-3 < 30 U/ml survived significantly longer than those with CA 15-3 > 30 U/ml (median 50+ versus 26 months, P < 0.02). Similarly, overall survival of patients with CA 125 < 35 U/ml was significantly higher in comparison with patients with CA 125 > 35 U/ml (median 34.5 versus 18.5 months, P < 0.001). CA 125, but not CA 15-3, maintained its prognostic value in the subgroup of patients with visceral metastases. Both markers were found to be independent prognostic variables in multivariate analysis according to Cox's model. CA 15-3 and CA 125 appeared to be powerful prognostic indicators, in addition to visceral metastases, in patients with advanced breast cancer.     

OVCA (CA125) second generation: technical aspects and serum levels in controls, patients with liver disease, pregnant women and patients with ovarian disease

An immunoradiometric method of the second generation (IR-MA II) is widely used to determine CA125 serum levels. In this study we have evaluated the performance characteristics of a commercially available IRMA CA125 II (Byk-Gulden, Sangtec Diagnostica). The CA125 serum levels were determined in several groups of patients (healthy women, pregnant women, subjects affected by benign and malignant ovarian cancer, patients with liver diseases) with two IRMAs CA125 II (Byk-Gulden, Sangtec Diagnostica and Centocor, Diagnostic Division) and IRMA CA125 I (Byk-Gulden, Sangtec Diagnostica). Our results show a good analytic performance of IRMA CA125 II (Byk-Gulden, Sangtec Diagnostica), a good correlation between IRMAs CA125 II (Byk-Gulden, Sangtec Diagnostica and Centocor, Diagnostic Division), but an unacceptable correlation between IRMAs CA125 II (Byk-Gulden, Sangtec Diagnostica and Centocor, Diagnostic Division) and IRMA CA125 I. A statistically significant difference was observed comparing the values obtained with both IRMAs CA125 II and IRMA CA125 I in the groups of patients. In contrast no statistically significant difference was observed when we compared the values obtained with IRMA CA125 II (Byk-Gulden, Sangtec Diagnostica) and IRMA CA125 II (Centocor, Diagnostic Division). CA125 serum values obtained with the second-generation kits were different from those obtained with the first-generation one; consequently, it is important, especially in the follow-up of cancer patients, that CA125 serum values be obtained with kits of the same generation. Our data seem to suggest the use of second-generation kits to determine CA125 serum levels.     

A case of clinically diagnosed Creutzfeldt-Jakob disease with serial MRI diffusion weighted images

We reported MRI findings in a 49-year-old woman with clinically diagnosed Creutzfeldt-Jakob disease (CJD). She was admitted to our hospital because of confusion, which initially appeared 5 weeks prior and was rapidly worsened. Two weeks later, she developed myoclonic jerks in her extremities with periodic synchronous discharges on EEG. Six months later, she became mutic. Brain MRI at 3 weeks after the admission demonstrated high signal intensities in the bilateral caudate nuclei and putamina on T2 weighted images (T2WIs). Diffusion weighted images (DWIs) showed hyperintensities in the basal ganglia and in the parietal and occipital cortices. Five weeks later, the abnormal intensities in the basal ganglia were still observed on T2WIs but decreased on DWIs. Five months later, the increased signal intensities in the basal ganglia had disappeared both on T2WIs and DWIs, but new hyperintensities appeared in the insula and the temporal area on DWIs. We concluded that DWIs may be useful for the demonstrations of a lesion in the cerebral cortex and the spread of lesions.     

Elevated nerve growth factor levels in the synovial fluid of patients with inflammatory joint disease

A novel pH shock extraction procedure was used to measure nerve growth factor (NGF) levels in both normal and inflamed synovial fluids using a sensitive and specific two-site enzyme linked immunosorbant assay. To date no data is available on NGF levels in normal synovial fluids. Synovial fluids were taken from 5 normal volunteers, 12 patients with rheumatoid arthritis and 10 patients with other inflammatory arthropathies. The mean +/- SEM NGF concentration in normal synovial fluids was 95 +/- 33.2 pg/ml (range 39.1-143.1 pg/ml), whereas the mean NGF concentration in the synovial fluids taken from patients with rheumatoid arthritis was 532.5 +/- 123.8 pg/ml (range 152-1686 pg/ml). The mean NGF concentration in patients with other inflammatory arthropathies was also raised (430.6 +/- 90 pg/ml; range 89-1071 pg/ml). The NGF concentrations were significantly higher in the synovial fluids from both inflamed groups (ANOVA p < 0.05) compared to normals. Raised levels of NGF in synovial fluid may contribute directly to joint inflammation via activation of inflammatory cells.     

MR imaging in pelvic inflammatory disease: comparison with laparoscopy and US

PURPOSE: To assess the value of magnetic resonance (MR) imaging in the diagnosis of pelvic inflammatory disease (PID) and to compare MR imaging with transvaginal ultrasonography (US) and laparoscopy. MATERIALS AND METHODS: Thirty consecutive patients hospitalized because they were clinically suspected of having PID underwent transvaginal US and T1-weighted spin-echo, T2-weighted turbo spin-echo, and inversion-recovery MR imaging at 1.5 T. All patients underwent laparoscopy after MR imaging. RESULTS: PID was laparoscopically proved in 21 (70%) patients. The MR imaging diagnosis agreed with that obtained with laparoscopy in 20 (95%) of the 21 patients with PID. The imaging findings for PID were as follows: fluid-filled tube, pyosalpinx, tubo-ovarian abscess, or polycystic-like ovaries and free pelvic fluid. Findings at transvaginal US agreed with those at laparoscopy in 17 (81%) of the 21 patients with PID. The sensitivity of MR imaging in the diagnosis of PID was 95%, the specificity was 89%, and the overall accuracy was 93%. For transvaginal US, the corresponding values were 81%, 78%, and 80%. CONCLUSION: MR imaging is more accurate than transvaginal US in the diagnosis of PID and provides information about the differential diagnosis of PID. MR imaging may reduce the need for diagnostic laparoscopy.     

Association of Ureaplasma urealyticum biovars with clinical outcome for neonates, obstetric patients, and gynecological patients with pelvic inflammatory disease

In this prospective study, the prevalence of the two Ureaplasma urealyticum biovars, parvo and T960, was determined in pregnant women and in gynecological patients colonized by ureaplasmas. Furthermore, we investigated the association of these biovars with gynecological complications and adverse pregnancy outcome. Isolates of U. urealyticum from 254 women were biotyped by a PCR method recently developed. The parvo biovar was found in 81% (206 of 254) of the patients, and the T960 biovar was found in 30% (76 of 254) of the patients; 6% (14 of 254) of the women were coinfected. Identical biovars were detected in mothers and their infants. Serial isolations or cultures from different sampling sites of the same individual revealed the same biovar. T960 was dominant in patients with pelvic inflammatory disease (57%) and patients who had had a miscarriage (42%), showed a higher rate of tetracycline resistance than did parvo isolates (55 versus 18%), and seemed to have more adverse effects on pregnancy outcome with regard to birth weight (2,500 versus 1,720 g), gestational age (35 versus 30 weeks), and preterm delivery (35 versus 77%).     

Gastrointestinal pH profiles in patients with inflammatory bowel disease

BACKGROUND: 5-Amino salicylic acid preparations are used in therapy for patients with inflammatory bowel diseases. The bioavailability of these drugs depends on their coating. AIM: To determine whether intraluminal pH is decreased by the presence of inflammation, thereby altering the release of 5-amino salicylic acid in the intestinal lumen. METHODS: Intraluminal gastrointestinal pH was measured by means of a radiotelemetry capsule in 12 healthy controls, in 12 patients with Crohn's disease (five with active disease), and in 11 patients with ulcerative colitis (seven with active disease). RESULTS: The median gastric pH values in the patient groups (Crohn's disease 2.4, range 1.5-4.1; ulcerative colitis 1.95, range 1.55-4.4) were significantly higher than those observed in the controls (1.55, range 0.95-2.6). In the small bowel and colonic segments, all the pH values of Crohn's disease patients were comparable to those of the controls, as were the pH values in the proximal small intestine and in the left colon in patients with ulcerative colitis. However, the latter group had higher pH values in the terminal ileum, the caecum and the right colon. Patients with active disease had comparable median gastrointestinal pH values to patients in remission. CONCLUSIONS: The luminal release of 5-amino salicylic acid might not be inhibited by low pH in patients with active inflammatory bowel diseases. This supports a safe disintegration of the slow release mesalazine preparations even in the presence of severe disease.     

Differentiating acute appendicitis from pelvic inflammatory disease in women of childbearing age

A retrospective study was performed to evaluate the usefulness of various historical, clinical, and laboratory findings in differentiating acute appendicitis from pelvic inflammatory disease (PID) in women of childbearing age. The records of all female patients presenting to the emergency department with abdominal pain who were found to have histologically proven appendicitis (n = 80) or PID confirmed on endocervical culture (n = 71) were reviewed. Clinically useful indicators favoring appendicitis included the presence of anorexia and the onset of pain later than day 14 of the menstrual cycle. Indicators favoring PID included a history of vaginal discharge, urinary symptoms, prior PID, tenderness outside the right lower quadrant, cervical motion tenderness, vaginal discharge on pelvic examination, and positive urinalysis. Despite these indicators, differentiating acute appendicitis from PID remains difficult.     

Femoral neck osteopenia in patients with inflammatory bowel disease

Bone morphogenetic proteins (BMPs) are considered to have important regulatory roles in skeletal embryogenesis and bone healing. Recombinant human BMPs (rhBMPs) have been shown to heal critical size defects and promote spinal fusion. We studied the effects of rhBMP-2 in an absorbable collagen sponge (ACS) on bone healing in a large animal tibial fracture model. Bilateral closed tibial fractures were created in 16 skeletally mature goats and reduced and stabilized using external fixation. In each animal, one tibia received the study device (0.86 mg of rhBMP-2/ACS or buffer/ACS), and the contralateral fracture served as control. The device was implanted as a folded onlay or wrapped circumferentially around the fracture. Six weeks following fracture, the animals were sacrificed and the tibiae harvested for torsional testing and histomorphologic evaluation. Radiographs indicated increased callus at 3 weeks in the rhBMP-2/ACS treated tibiae. At 6 weeks, the rhBMP-2/ACS wrapped fractures had superior radiographic healing scores compared with buffer groups and controls. The rhBMP-2/ACS produced a significant increase in torsional toughness (p = 0.02), and trends of increased torsional strength and stiffness (p = 0.09) compared with fracture controls. The device placed in a wrapped fashion around the fracture produced significantly tougher callus (p = 0.02) compared with the onlay application. Total callus new bone volume was significantly increased (p = 0.02) in the rhBMP-2/ACS fractures compared with buffer groups and controls regardless of the method of device application. The rhBMP-2/ACS did not alter the timing of onset of periosteal/endosteal callus formation compared with controls. Neither the mineral apposition rates nor bone formation rates were affected by rhBMP-2/ACS treatment. The increased callus volume associated with rhBMP-2 treatment produced only moderate increases in strength and stiffness.     

Psychiatric side effects of ofloxacin used in the treatment of pelvic inflammatory disease

The Clinical Effectiveness Group of the Medical Society for the Study of Venereal Diseases and the Association of Genitourinary Medicine published guidelines on the management of pelvic inflammatory disease in 1999. Subsequently, the use of ofloxacin has increased in our department. However, ofloxacin can cause serious psychiatric side effects, particularly in those with a past psychiatric history. This is of relevance to genitourinary medicine (GUM) physicians as there is a high prevalence of psychiatric illness amongst patients attending GUM clinics. We present two cases of ofloxacin causing severe psychiatric symptomatology, in one case causing an acute psychotic reaction. It is recommended a psychiatric history is taken prior to prescribing ofloxacin and that consideration is given to alternative therapy for those with previous psychiatric illness.     

Systematic sextant biopsies improve preoperative prediction of pelvic lymph node metastases in patients with clinically localized prostatic carcinoma

PURPOSE: An algorithm including the results of systematic sextant biopsies was statistically developed and evaluated to predict the probability of pelvic lymph node metastases in patients with clinically localized carcinoma of the prostate. MATERIALS AND METHODS: Clinical stage, serum prostate specific antigen concentration, Gleason score, number of positive biopsies, number of biopsies containing any Gleason grade 4 or 5 cancer and number of biopsies predominated by Gleason grade 4 or 5 cancer were recorded in 345 patients undergoing pelvic lymph node dissection and correlated with the incidence of lymph node metastases. Multivariate logistic regression, and classification and regression trees analyses were performed. RESULTS: In univariate analysis all variables had a statistically significant influence on lymph node status. Logistic regression showed that the amount and distribution of undifferentiated Gleason grade 4 and 5 cancer in the biopsies were the best predictors of lymphatic spread followed by serum prostate specific antigen. Classification and regression trees analysis classified 79.9% of patients who had 3 or fewer biopsies with Gleason grade 4 or 5 cancer and no biopsies predominated by undifferentiated cancer as a low risk group. In this group positive lymph nodes occurred in only 2.2% (95% confidence interval 0.8 to 4.7%). CONCLUSIONS: Including the results of systematic sextant biopsies substantially enhances the predictive accuracy of algorithms that define the probability of lymph node metastases in prostatic cancer. Patients thus defined as having no lymphatic spread could potentially be spared pelvic lymph node dissection before definitive local treatment.     

Quantitative spectral electroencephalography in predicting survival in patients with early Alzheimer disease

OBJECTIVE: To determine whether measures of quantitative spectral electroencephalography (EEG) can predict survival in patients with early Alzheimer disease. DESIGN: Prospective cohort study; median duration of follow-up was 4.4 years in survivors and 2.6 years in nonsurvivors. Cox proportional hazards models, with adjustment for age and sex were used to estimate relationships between EEG measures and survival. Log relative percentage values of EEG bands were used as predictors. SETTING: Outpatient university memory clinic. PARTICIPANTS: One hundred one consecutively referred patients with early probable Alzheimer disease according to National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria were studied with EEG at the time of diagnosis. The mean age of the patients was 79.2 years, which was higher than in previous EEG studies. MAIN OUTCOME MEASURE: Mortality. RESULTS: Fifty-one patients (50.5%) died during follow-up, with a median survival time in all patients of 4.1 years. The following EEG variables were significantly associated with increased risk of mortality: from parieto-occipital leads, higher theta (hazard ratio, 2.05; 95% confidence interval, 1.15-3.66; P<.05), lower alpha (hazard ratio, 0.43; 95% confidence interval, 0.25-0.76; P<.01), and lower beta (hazard ratio, 0.38; 95% confidence interval, 0.22-0.68; P<.001) activity; and from frontocentral leads, higher theta activity (hazard ratio, 2.07; 95% confidence interval, 1.17-3.66; P<.05). Stepwise Cox regression analysis showed that loss of parieto-occipital beta (P<.01) and alpha (P<.05) power were independent and significant predictors of mortality. Both beta (12.6-35.4 Hz) and alpha (7.5-12.5 Hz) activity remained significantly associated with mortality after adjustment for education, dementia severity, symptom duration, level of cognitive function, presence of extrapyramidal symptoms or hallucinations, presence of vascular risk factors, and presence of leukoaraiosis or local cortical atrophy. CONCLUSIONS: Decreases of beta and alpha activity on quantitative spectral EEG are independent predictors of mortality in patients with early Alzheimer disease. In the clinical context, the use of EEG technology for prediction of survival in individual patients remains to be determined.     

Elevated factor J levels in synovial fluid from patients with inflammatory arthropathies

Factor J (FJ) is a complement inhibitor that is able to regulate in vitro both the classical and alternative human complement pathways. In the search of its biological significance, we have analyzed FJ levels in synovial fluid from patients with different arthropathies, in which IL-6 levels had been previously measured. The pathologies included in this study were: rheumatoid arthritis (RA) (n = 21), crystal deposition diseases (CDD) (n = 6), osteoarthritis (OA) (n = 23), spondyloarthritis (SpA) (n = 3) and other inflammatory arthropathies (OIA) (n = 4). We found a good correlation between IL-6 and FJ levels (r = 0.33, p = 0.0132) in the 57 processed samples. Synovial fluids had high levels of IL-6 (median: 3000 pg/ml). Besides, we found that FJ levels were elevated (241 +/- 429 micrograms/ml) when compared with NHS (5.32 +/- 2.82 micrograms/ml). Considering OA patients as control group for non-inflammatory situation, we found that FJ levels were significantly elevated in inflammatory patients only if RA patients were excluded. Furthermore, there were also significant differences with CDD patients. In addition, we have examined the presence of this inhibitor in synovial fluid by Western blot after running gels at acid pH and electrophoretical transference at the same pH. In these experiments, we evidenced the presence of a cationic protein immunoreactive with polyclonal and monoclonal anti-FJ antibodies. In conclusion, FJ levels are elevated in pathological synovial fluids. FJ could be an acute phase reactant as other molecules present in the synovial fluid, or could be shed from extracellular matrix as a consequence of the high enzymatic activity present in the articular fluid or as a response to the inflammatory stimulus.     

Detection of serum antibodies to Chlamydia trachomatis in patients with chlamydial and nonchlamydial pelvic inflammatory disease by the IPAzyme Chlamydia and enzyme immunoassay

A novel serological test, IPAzyme Chlamydia (Savyon Diagnostics Ltd., Beer Sheva, Israel), was compared with an enzyme immunoassay (EIA) for the ability to detect serum immunoglobulin G and A antibodies in the diagnosis of acute chlamydial pelvic inflammatory disease. In comparison with cell culture, which is the "gold standard," IPAzyme Chlamydia and EIA exhibited sensitivities of 63 and 68% and specificities of 76 and 87%, respectively. Thus, IPAzyme Chlamydia offers no advantages over the EIA, and neither serological test can be recommended for the diagnosis of acute Chlamydia trachomatis infection. So far, conventional cell culture remains the most reliable diagnostic test for chlamydial pelvic inflammatory disease.     

Clinical determinants of mortality in patients with angiographically diagnosed ischemic or nonischemic cardiomyopathy

OBJECTIVES: We sought to characterize the clinical determinants of mortality in patients with angiographically diagnosed ischemic or nonischemic cardiomyopathy. BACKGROUND: Patients with ischemic cardiomyopathy may have a worse prognosis than patients with nonischemic cardiomyopathy. Few studies have assessed the effect of ischemic versus nonischemic etiology on outcomes. METHODS: We analyzed prospectively collected data on 3,787 patients with a left ventricular ejection fraction < or = 40% who underwent coronary angiography. Patients were considered to have ischemic cardiomyopathy (n = 3,112) if they had a history of myocardial infarction, percutaneous transluminal coronary angioplasty, coronary artery bypass graft surgery or at least one major epicardial coronary artery with > or = 75% stenosis; all others were considered to have nonischemic cardiomyopathy (n = 675). RESULTS: The median age, ejection fraction and proportion of patients with New York Heart Association functional class III or IV symptoms for the nonischemic and ischemic groups were 55 years versus 63 years, 27% versus 32% and 57% versus 25%, respectively. After adjustment for baseline clinical risk factors and presenting characteristics, ischemic etiology remained an important independent predictor of 5-year mortality (p < 0.0001). The extent of coronary artery disease was a better predictor of survival than ischemic or nonischemic etiology (log likelihood chi-square 700 vs. 675, respectively). CONCLUSIONS: Ischemic etiology is a significant independent predictor of mortality in patients with cardiomyopathy. However, the extent of coronary artery disease contributes more prognostic information than the clinical diagnosis of ischemic or nonischemic cardiomyopathy. Further research is needed to refine the clinical definition of ischemic cardiomyopathy so that physicians can appropriately prescribe treatment and accurately predict outcome.
