Abstract
4536 Background: The poor prognosis associated with locally advanced esophageal cancer prompted an evaluation of combined modality treatments including neoadjuvant radiochemotherapy in combination with surgery. However, it has been well established that only patients with a complete pathological response to neoadjuvant therapy will have a significant survival benefit. Therefore, predictive markers to allow a tailored radiochemotherapy are needed. The aim of this study was to examine the association of the protein expression of survivin, an inhibitor of apoptosis, with histopathologic response to neoadjuvant radiochemotherapy and prognosis of patients with locally-advanced esophageal cancer. Methods: 59 patients with esophageal cancer (cT2–4, Nx, M0) received neoadjuvant radiochemotherapy (cisplatin, 5-FU, 36 Gy) followed by esophagectomy. Histomorphologic regression was defined as major response when resected specimens contained less than 10 % and as minor response when resected specimens contained more than 10 % of residual vital tumor cells. Pre- and post-therapeutic intratumoral protein expression of survivin was determined and correlated with clinicopathologic parameters. Results: The pre-therapeutic intratumoral survivin protein expression was not associated with any clinicopathologic factor, including histopathologic response and prognosis. Survivin protein expression was significantly reduced during neoadjuvant therapy, showing lower levels in post-therapeutic tumor samples (p<0.01). Higher postoperative survivin levels were significantly associated with a higher ypT-stage (p<0.009), a poorer histopathologic response (p<0.01) and a shorter overall survival (p<0.028). Conclusions: The intratumoral protein expression of survivin was significantly down-regulated during neoadjuvant therapy, whereas a higher survivin level after pre-operative therapy was significantly associated with a worse histopathologic response and prognosis. Therapeutic strategies which are able to reduce survivin expression or to block survivin mediated pathways might increase the histopathologic response rate and prognosis in the multimodal therapy of patients with locally-advanced esophageal cancer. No significant financial relationships to disclose.

Abstract
The updated results of current pathomorphological investigations in SIV-infected rhesus monkeys (Macaca mulatta) are summarized. After experimental infection with several SIVmac251 subtypes and various vaccination trails, 147 rhesus monkeys were morphologically examined until now. The pathology of the gastrointestinal tract in SIV-infected animals resembled those of human cases with HIV and AIDS. Alterations were considered to be primary SIV-induced (SIV enteropathy, giant cell disease) or secondary caused by opportunistic agents. Typical secondary gastrointestinal opportunistic infectious agents were parasites (Cryptosporidium sp., Trichuris sp., Trichomonas sp., Spironucleus sp.), viruses (cytomegalovirus, adenovirus) and bacteria (Mycobacterium simiae). Five animals developed malignant lymphomas involving the intestinal tract. The present observations revealed that SIV infection of rhesus monkeys provide an excellent model for studies on the pathogenesis of HIV in man.

Abstract
OBJECTIVE To report the visual and anatomic outcome after surgical drainage of suprachoroidal hemorrhage according to hemorrhage severity. DESIGN A retrospective chart review. PARTICIPANTS Forty-eight consecutive eyes undergoing surgical drainage of a suprachoroidal hemorrhage at The Medical College of Wisconsin were examined. INTERVENTION Demographic and clinical data were abstracted from patients' medical records. Eyes were classified into four categories of increasing hemorrhage complexity: (1) nonappositional choroidal hemorrhage without vitreous or retinal incarceration in the wound (12 eyes); (2) centrally appositional choroidal hemorrhage without vitreous or retinal incarceration in the wound (17 eyes); (3) choroidal hemorrhage with associated vitreous incarceration in the wound (11 eyes); and (4) choroidal hemorrhage with associated retinal incarceration in the wound (8 eyes). MAIN OUTCOME MEASURES Visual acuity, rate of persistent hypotony, and incidence of irreparable retinal detachment after surgical drainage for four classes of suprachoroidal hemorrhage were defined. RESULTS Overall, 11 (23%) of 48 eyes had no light perception (NLP) vision develop, 9 (19%) of 48 eyes had persistent postsurgical hypotony (intraocular pressure < 6), and 21 (64%) of 33 eyes with retinal detachment enjoyed successful retinal reattachment surgery. A definite trend toward an increased rate of NLP vision (P < 0.02), persistent hypotony (P < 0.05), and irreparable retinal detachment (P = 0.11) was observed with increasing suprachoroidal hemorrhage complexity. Eyes with retinal incarceration, compared to eyes without retinal incarceration, had an increased rate of NLP vision (63% vs. 15%; P < 0.01), persistent postsurgical hypotony (50% vs. 13%; P < 0.05), and irreparable retinal detachment (50% vs. 20%; P = 0.07). CONCLUSIONS Eyes requiring surgical drainage of a suprachoroidal hemorrhage have a guarded prognosis, with a poorer outcome associated with increasing hemorrhage complexity. A classification system incorporating choroidal apposition, and vitreous and retinal incarceration in the wound, provides a format for reporting and assessing the efficacy of management strategies in this condition.

Abstract
PURPOSE To determine the effect of peripheral retinal laser photocoagulation (PLP) on visual acuity, intraocular inflammation, and other ocular findings, including retinal neovascularization in eyes with pars planitis. METHODS A retrospective chart review of eyes with pars planitis that had undergone PLP. RESULTS Twenty-two eyes in 17 patients with pars planitis had undergone treatment with PLP at 2 centers. The mean age at the time of treatment was 19.3 years. Following treatment, mean follow-up was 16.3 months (range, 6 to 37 months). Mean visual acuity was 20/60 preoperatively and 20/50 postoperatively. This level of improvement was not statistically significant (P > .10), but there was a statistically significant decrease in the use of corticosteroids between the preoperative examination and the last postoperative examination (86% versus 27%, P < .05). There was also a statistically significant decrease in vitritis at the last follow-up (P = .0008) and a decrease in neovascularization of the vitreous base (P = .03) and in clinically apparent cystoid macular edema (P = .02). Epiretinal membranes were noted in 23% of eyes preoperatively and in 45% of eyes postoperatively. Only one of these epiretinal membranes was considered to be visually significant. One eye developed a tonic dilated pupil, which slowly improved. CONCLUSIONS Although the long-term natural history of clinical findings in pars planitis is not well documented, PLP appears to decrease the need for corticosteroids while stabilizing visual acuity. It also appears to decrease vitreous inflammation. PLP has few complications and should be considered in patients with pars planitis who are unresponsive or have adverse reactions to corticosteroids.

Abstract
OBJECTIVE To derive and evaluate prediction models for patients who had undergone coronary artery bypass grafting (CABG) and had a difficult postoperative course. DESIGN Observational. SETTING Midwestern hospital specializing in high-risk CABG procedures. PATIENTS One hundred eighty-three patients who stayed at least 10 consecutive days in the intensive care unit after a CABG procedure. OUTCOME MEASURE Death within 60 days of surgery. INTERVENTION None. RESULTS The final logistic regression prediction models included the following findings: pulmonary capillary wedge pressure, cardiac index, heart rate, urine output, positive end-expiratory pressure, blood urea nitrogen levels, and the arterial pressure of carbon dioxide. The model was able to stratify patients into four risk groups with observed 60-day mortality rates of 0.0% (n = 107), 21% (n = 39), 55% (n = 20), and 88% (n = 17). Preoperative patient information was not associated with prognosis for these patients. CONCLUSIONS The findings suggest that a risk model that is specific for patients who have undergone CABG and is based on postoperative findings may provide useful prognostic information for patients who are having a difficult postoperative course.

Abstract
Proximal myotonic myopathy (PROMM) is an autosomal dominantly inherited multisystemic disorder characterized by myotonia, proximal muscle weakness, and cataracts. This disorder is not linked to the gene locus of myotonic dystrophy (DM). We describe three new families with PROMM. In all patients, CTG repeats of the DM gene in DNA from blood leukocytes were normal. MRI of the brain revealed a consistent pattern of marked white matter hyperintensity on T2-weighted images in four patients; two additional patients had similar but mild to moderate MRI abnormalities. The morphology of these abnormalities is unknown. Clinical symptoms of brain disease were not consistent and included mental changes with hypersomnia, parkinsonian features, stroke-like episodes, and seizures. The causative relationship of these clinical features with the MRI white matter abnormalities remains to be established. Our observations suggest that PROMM may involve the brain.

Abstract
The first quality assurance, audit and control system in the Hungarian "'health" care industry" is described for the medical specialty of radiotherapy. The prerequisites of the elaboration of the programme were an exact knowledge of the current Hungarian infrastructural and staffing conditions, and the radiotherapeutic activities. The recommendations cover the 5 medical universities including the national institute (the Debrecen, Pécs, Semmelweis, Szent-Györgyk Albert Medical Universities, and Haynal Imre University of Health Sciences) and the 5 regional oncological centres in hospitals (Jósa András, Markusovszky, Petz Aladár, Szentpéteri kapu and Uzsoki Hospitals). The departmental functions (patient care, teaching-education, research work and scientific organizing activity) and the structure (organization, infrastructure, staffing conditions, etc.) are described first, followed by the therapeutic principles and clinical process (patient referral and selection, decision-making, priorities in therapy initiation, treatment preparation and execution, etc.). The informal daily/weekly quality assurance programme long applied in the routine patient care has been formalized and supplemented with a weekly audit conference. In the course of the medical audit, all relevant clinical data are reviewed and scored by an internal or an external expert (not participating directly in the treatment process), e.g. for the adequacy of the medical decision preparative process, conformation to the institutional treatment protocol, equipment selection, treatment planning, simulation and portal film, etc. If a major deviation is detected, an immediate correction is initiated; minor deviations need analysis and then preventive and correcting action. As concern the audit of the other activities of the departments, the important indicators and their minimally desirable level are defined. The final goal of the implementation of this programme is high-precision radiotherapy with the best achievable treatment result.

Abstract
PURPOSE To determine the value of taking simultaneous stereo photographs of the optic nerve head as a basis for identification of patients with glaucoma. METHODS Two hundred fifty-eight patients received complete ophthalmological examinations and were ranked on a scale of 1-5 regarding the likelihood of their having glaucoma. Each eye was also photographed using the NIDEK camera, providing stereo pairs of the optic nerve head. The same patients were reclassified by two independent masked observers on the same scale of 1-5, based solely on examination of the photographs. RESULTS Examination of stereo photographs alone provided maximum sensitivity of 75% and specificity of 95% in identification of glaucoma patients when photographic readings were compared with all available clinical information. CONCLUSIONS Stereo photographs of the optic nerve head can be used for glaucoma detection with an accuracy that is significantly greater than simple tonometry and with a sensitivity that is equivalent to screening with computerized perimetry.

Abstract
The present study was designed to compare the prostate cancer detection rate, sensitivity, specificity, and positive predictive value of digital rectal examination (DRE) and serum prostatic specific antigen (PSA) in a consecutive cohort of males presenting to a single institution with clinically significant prostatism. The study population was comprised of 224 consecutive males with clinically significant prostatism referred to the Prostate Center at the Medical College of Wisconsin between June 1990 and December 1991. Subjects were considered to have clinically significant prostatism if they elected to pursue medical or surgical therapy following exclusion of carcinoma of the prostate. The initial examination consisted of a Boyarsky symptom score assessment, DRE, uroflowmetry, postvoid residual determination, serum PSA level, and transrectal prostatic ultrasonography. Subjects with an abnormality on DRE or serum PSA > 4 ng/dl were advised to undergo transrectal prostatic biopsy. Of the 224 subjects, 40 (17.9%) had an abnormal DRE and 57 (25.4%) had an elevated serum PSA > 4 ng/dl. The overall detection rate of prostate cancer in the study population was 6.7%. The prostate cancer detection rates for PSA alone and DRE alone were 5.8% and 5.3%, respectively. The sensitivity, specificity, and positive predictive values of PSA alone were 86.7%, 80.9%, and 25.0% and of DRE alone 80.0%, 86.3%, and 30.0%, respectively. Receiver operator characteristic (ROC) curves were constructed for the entire study population in order to compare the screening measures serum PSA and PSA density. The area under the curves was 0.88 for both tests, indicating that these screening tests for prostate cancer were not significantly different. The present study demonstrated that males with clinically significant prostatism represent a high risk cohort for detecting prostate cancer. DRE and PSA are equally effective measures for detecting prostate cancer. PSA density does not offer any advantage over serum PSA in screening for prostate cancer, except in the subset of patients with a normal DRE and serum PSA levels between 4.0 and 9.9 ng/dl.

Abstract
The results of a comprehensive investigation of the effect of a 20-minute submaximal (Z1) and exhausting (Z2) work load in a group of 8 healthy volunteers on the amino acid and nitrogen metabolism indicate that, as compared with the mild and significant increase of alanine and drop of leucine (all P < 0.05) during the minor load, after an exhausting load a significant rise and concurrent drop of isoleucine, threonine, ornithine, leucine, serine, glycine, asparagine and glutamine (P < 0.01) occurs and a slightly significant drop of methionine and citrulline, while the total amino acid level is practically unaltered. The rise of alanine suggests the existence of a glucose-alanine cycle. The drop of branched amino acids is probably due to their enhanced entry into muscles, the drop of ornithine and citrulline is most probably due to inhibition of ureogenesis in the liver due to lactate and pyruvate accumulation. Exercise caused moreover a significant rise of serum ammonia and uric acid. N-urea changed only little and on average had a declining tendency. The results support data, that intense exercise increases the demands of the human organism for high quality dietary protein intake.

Abstract
Myotonia congenita (Thomsen's disease) is a muscular disorder with autosomal dominant inheritance. The main symptom is muscle stiffness caused by hyperexcitability of the muscle cell membranes. The disorder is noticeable at birth or in early childhood and is progressive. Muscle hypertrophy is a common sign. Recessive generalized myotonia (Becker) resembles myotonia congenita in many respects, but there are also differences, e.g. later onset and transient muscle weakness experienced by many patients during muscle exertion after rest. The clinical signs usually progress over several years and then remain stable. The decisive criterion for the differential diagnosis of Thomsen or Becker type myotonia is the mode of inheritance. Both disorders are caused by defects of the gene, situated on chromosome 7, that is responsible for the normal functioning of the chloride channels in the muscle cell membranes. The differences between the two types of myotonia are probably caused by different mutations of this gene. The present paper also describes two animal models of myotonia (the myotonic goat and the myotonic mouse), which simulate the dominant and recessive types of human myotonia, respectively. The models have been very helpful in research into the origins of myotonia.

Abstract
The objective of this study was to derive and validate a simple scoring system that predicts risk of short-term mortality in elderly patients hospitalized with acute myocardial infarction (AMI) and to compare this derived score with the MedisGroups admission severity score. A myocardial infarction severity score (MISS) was derived from a database of clinical information abstracted using MedisGroups and follow-up information on 30-day mortality status. The MISS was validated and compared with the MedisGroups Admission Severity Groups (ASGs) in a separate database. The derivation set included 2,037 Medicare patients 65 years old or older with confirmed AMI who were randomly selected from patients discharged from hospitals in seven states during 1985. The validation set consisted of 6,323 patients from the 1988 MedisGroups comparative database who were at least 65 years of age and had confirmed AMI. Multivariate logistic regression analysis found a set of nine abnormal patient characteristics that independently predict 30-day mortality. There was good agreement between mortality rates predicted by the logistic model and observed mortality rates in the validation population. This regression model was then simplified to an additive score where eight of the characteristics were weighted as one point and one characteristic was weighted as two points. The MISS is the sum of the points for each patient. In the validation dataset, the 1,373 patients with the lowest MISS scores had a mortality rate of 4.6% and the 400 patients with the highest MISS scores had a mortality rate of 64%.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-one patients with symmetric nonproliferative retinopathy who underwent extracapsular cataract extraction and intraocular lens implantation were followed up postoperatively for an average (+/- standard deviation) of 18 +/- 7 months to determine the incidence of progression of diabetic retinopathy, the final visual acuity, and factors predictive of progression of retinopathy and final visual acuity. Progression of retinopathy, defined as the development of clinically significant macular edema, an increase in intraretinal hemorrhages or hard exudate, or the development of proliferative diabetic retinopathy, was assessed in both eyes of 19 patients; in two remaining patients, dense preoperative cataract in the fellow eye precluded comparison of retinopathy progression in the operated-on eye to progression in the fellow eye. Overall, retinopathy progressed in 14 of 19 operated-on eyes (74%). Cataract extraction was highly associated with asymmetric progression of nonproliferative retinopathy; it progressed only in the operated-on eye in seven of 19 patients (37%), but in no patients did progression occur in the fellow eye alone (P = .0078). Women had a significantly increased risk of progression of retinopathy in the operated-on eye compared to men (P = .005). Visual acuity improved in 19 of 21 operated-on eyes (86%); however, only 11 eyes (52%) achieved a visual acuity of 20/50 or better and only six eyes (14%) achieved a visual acuity of 20/25 or better. In only five eyes was the final visual acuity in the operated-on eye more than two lines better than the final visual acuity in the fellow eye.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Staging of malignant lymphomas, monitoring of response to therapy and regular follow-up of treated patients can properly be performed by new diagnostic imaging modalities. Diagnosis of subdiaphragmatic nodal involvement by ultrasonography and computed tomography is based on enlargement of lymph nodes. Lymphography is the only method which can depict pathologic internal architecture in normal sized lymph nodes. Of 82 patients there were 72 on admission without known subdiaphragmatic nodal disease. Of these 22 (30.5%) were found to have nodal involvement in this region. Suggested diagnostic algorhythm is shown on flow diagram.

Abstract
Authors analyse the value of intravenous pyelography, ultrasonography, computed tomography, angiography and fine needle aspiration biopsy in the detection, differentiation and staging of renal space-occupying lesions, on the basis of examinations performed in 158 patients, in comparison with results of surgery and/or clinical follow up. Their conclusion is that ultrasonography plays a major role in the detection and differentiation of these lesions, intravenous pyelography is only a complementary method, while computed tomography can provide diagnosis in cases with uncertain ultrasonographic findings. Staging has to be based on computed tomography. The role of angiography and fine needle aspiration biopsy is limited they need to be performed in a few selected cases only.

Abstract
Body fat distribution as measured by the ratio of waist circumference to hip circumference (WHR) is now accepted as an important risk factor for a number of diseases. This study evaluated the association of WHR and coronary artery disease (CAD). Measurements included the subjects' height, weight, waist girth, hip girth, significant CAD on coronary angiography, and cholesterol levels. A history of myocardial infarction, angina, diabetes or hypertension was obtained from subject interviews. The subjects were analyzed in two age groups: younger than age 60 (88 men and 39 women) and age 60 or older (85 men and 63 women). For older women the relative odds of CAD comparing women at the 75th percentile of WHR to women at the 25th percentile was 3.67 (P = 0.003), with a 95 percent confidence interval of 1.57-8.57. The relative odds was reduced to 2.80 after adjusting for all other risk factors. WHR was significantly associated with angiographic evidence of CAD in all women combined after adjusting for age (P = 0.0004), but it was not significantly associated with CAD in younger women or in men. The results suggest that in older women the risk of CAD increases with a greater percentage of body fat in the abdomen.
