Abstract
The objective of this work is to study the relation between the variations of the plasmatic aminogram, and the nutritional state of the patient with chronic kidney failure on hemodialysis. We studied 79 patients with chronic kidney failure undergoing hemodialysis treatment, with and evolution of 46 +/- 37 months. They were subjected to a dietary questionnaire, and anthropometric study after dialysis (body mass index, triceps skin fold, muscular circumference of the arm), and determination of the levels of serum amino acids after a pre-dialysis nocturnal fast half way through the week, and finally a record is made of the number of times each patient was hospitalized in the 6 months prior to the study. In the amino acids with a pyruvate origin, there is a significant reduction of alanine (p: 0.002), serine (p: 0.004), and methionine (p: 0.001), and a significant increase of glycine, cystathionine, and cystine (p: 0.0001), with the Glycine/Serine coefficient being elevated (p: 0.001). All amino acids with a ketoglutarate origin are increased significantly (p < 0.007), except glutamine which is decreased (p: 0.0009), and arginine which does not show any significant differences. The essential amino acids are decreased in relation to the non-essential ones (p: 0.0001), although if they are compared with the normal values, only threonine is decreased (p: 0.001). Of the rest, histidine, isoleucine (p: 0.0001) and phenylalanine (p: 0.001) are significantly increased. The tyrosine/phenylalanine coefficient is decreased (p: 0.001). The daily ingestion of protein is correlated negatively with alanine, proline, hydroxyproline, and aspartic acid. The anthropometric parameters are correlated positively with the branched amino acids, alanine and proline. Finally, the number of hospital admissions in the last 6 months, is correlated positively with valine, leucine, phenylalanine, and glutamic acid. In conclusion, we consider that the increase of the glycine/serine, phenylalanine/serine and non essential/essential coefficients, is related to alterations of the metabolism, intrinsic to the condition of uremia, while the alterations of the levels of branched amino acids is related to the nutritional condition of the patients.

Abstract
Thirty-two isolates of clinically significant Streptococcus pneumoniae from 11 human immunodeficiency virus (HIV)-seropositive patients with single or multiple episodes of pneumonia were characterized by antibiotic susceptibility testing, serotyping, ribotyping, and repetitive extragenic palindromic polymerase chain reaction (REP-PCR). The isolates comprised 10 serotypes, 12 ribotyping patterns, and 12 REP-PCR patterns. There was close but not absolute correlation between techniques. By combining these characterization methods, 14 strains were identified. Five strains were found in > 1 patient, suggesting their frequent occurrence in this population. Two isolates of different serotype from 1 patient were highly related by ribotyping and REP-PCR, suggesting possible in vivo serotype change. Acute infection was associated with single strains or coinfection by distinct strains. Recurrent pneumonia was identified as relapse with the same strain or reinfection with new strains. The molecular characterization of pneumonococci from HIV-seropositive persons refines our understanding of pneumonococcal infection in these patients.

Abstract
This study determined the temporal trends and factors associated with the rates of performance of tibial osteotomies from 1985 to 1990 in Ontario, Canada and the United States. The Health Care Financing Administration, Ontario Health Insurance Plan, and National Hospital Discharge Survey databases were used to determine the number of osteotomies from 1985 to 1990. Osteotomy rates decreased in both countries approximately by 11% to 14% per year in patients 65 years and older and by 3% to 4% per year in patients younger than 65 years. Men received twice as many osteotomies as women in both countries. In the United States, the average rate of tibial osteotomies was 2 to 3 times lower than in Ontario.

Abstract
OBJECTIVE To ascertain whether delayed diagnosis or type of orchidectomy affected outcome for men with non-seminomatous germ cell tumours (NSGCT). PATIENTS AND METHODS The case notes of 454 men resident in the west of Scotland with a diagnosis of NSGCT between 1975 and 1989 were retrospectively reviewed. The clinical record was available for 442 (97%) and included information on time to diagnosis in 92% and diagnostic surgery in 97%. The study end-point for orchidectomy was loco-regional recurrence and for diagnostic delay was survival. RESULTS A significant minority of men (10.4%) underwent a scrotal orchidectomy or had a scrotal incision before an inguinal orchidectomy (9.4%). More scrotal incisions were performed on patients under the care of general surgeons (28%) than of urologists (12.1%). Of the men who had scrotal surgery, one of 78 (1.3%; 95% CI, 0-4%) developed loco-regional disease as the initial site of recurrence, compared with none of 318 men undergoing inguinal orchidectomy. The median time to diagnosis was 3 months. There was no relationship between time to diagnosis and tumour extent at presentation. A diagnostic delay of > 3 months was associated with inferior survival in univariate analysis, but delayed diagnosis was not an independent influence on survival after adjustment for the major prognostic factors--tumour extent, year of diagnosis and treatment unit. CONCLUSIONS These results suggest that scrotal incision is unlikely to affect the risk of loco-regional recurrence and that effective cytotoxic therapy has probably reduced the prognostic importance of delayed diagnosis on survival of men with NSGCT.

Abstract
This paper describes the temporal pattern of germ cell testicular cancer in Scotland between 1960 and 1990. The effect of age on the prognosis of patients with non-seminomatous germ cell tumours (NSGCT) has been assessed by studying all patients presenting in the West of Scotland between 1975 and 1989. Between 1960 and 1990, the number of testicular germ cell tumours registered has increased more than 2-fold; mortality rates have declined equally dramatically. Univariate and multivariate analysis of the data obtained on 440 patients with NSGCT showed age was not a prognostic factor influencing survival. 52 were patients over 40 years at presentation; their 5 years survival was 71% compared with 79% in the younger patients (n = 388). This small survival difference is probably explained by the higher proportion of older patients treated before 1980. Treatment for this older group should be approached with the same curative intent as for younger patients and the same expectation of success.

Abstract
The concept of an artificial interatrial communication in application of the Fontan procedure in high risk patients has raised the problem to exactly determine the shunt amount. This experimental study shows that in vitro flow studies of interatrial communications can be performed without animal blood and PTFE membranes respectively. Furthermore the simulation of an pulmonary vascular venous flow is not necessary. Additionally a new formula with acceptable accuracy for flow estimation is derived from the presented data obtained by this study.

Abstract
OBJECTIVE To examine the prevalence and predictors of repeat HIV testing. DESIGN, SETTING AND PARTICIPANTS Cross-sectional data from two random household-based and bar-based samples of gay/bisexual men in two medium-size cities (Tucson, Arizona and Portland, Oregon) with substantial numbers of AIDS cases, in 1992 (n = 2602). MAIN OUTCOME MEASURE The prevalence and predictors of repeat testing among men who reported being HIV-tested at least once but not being HIV-positive (n = 1583). RESULTS In total, 51% of the sample had been tested three or more times, and 15% were tested more than once every 6 months. Men with higher risk were more likely to be repeatedly tested, although oral but not anal risk was a significant predictor of repeat testing in regression analyses. Men who did not know the HIV status of their primary partner were less likely to be repeatedly tested. Men who perceived that social norms favored secondary prevention, specifically adherence to medical recommendations for the treatment of HIV infection, and who communicated more often about testing were more likely to be repeatedly tested. CONCLUSIONS Policy and clinical recommendations for repeat testing must be based on consideration of the complexity and multi-faceted nature of repeat testing. For some individuals, repeat testing may play a legitimate role in HIV prevention by reinforcing safe behavior and providing confirmation of HIV-negative status. However, for others repeat testing may indicate a need for different or more intensive interventions to encourage safe sex.

Abstract
OBJECTIVES To describe the sexual practices of high school students; to describe the process of development of a school-based AIDS prevention program; and to evaluate the effect of this program on students' AIDS-related knowledge, attitudes and AIDS-preventive behaviors. SUBJECTS AND METHODS A cluster-randomized, controlled trial with pretest/post-test evaluation was conducted in four demographically similar public high schools in a semi-urban district of Metro Manila, the Philippines. Of 845 high school students who participated in the baseline survey, 804 (95%) completed a postintervention questionnaire. INTERVENTION An AIDS prevention program was developed by public high school teachers together with local AIDS experts, social scientists and health educators. The teacher-led AIDS program was designed to provide students with accurate information about AIDS, particularly in dispelling misconceptions about casual contagion, to foster positive attitudes towards people with AIDS and to develop skills aimed at clarifying values and assessing intended behavior. RESULTS At baseline, 11% of students (20% of males and 4% of females) reported ever having had sexual intercourse (mean age 14 years). Among these, condom use was low (24%). After implementation of the AIDS prevention program, statistically significant effects favoring the intervention group were observed in knowledge and attitudes towards people with AIDS. While there was no statistically significant overall effect on intended preventive behavior, the program appeared to delay the students' intended onset of sexual activity. CONCLUSIONS A sizable number of Filipino high school students are sexually active but condom use is low. School-based AIDS prevention programs can be developed and implemented in developing countries with the assistance of school personnel to address sexual issues. Our program was successful in increasing AIDS-related knowledge and improving attitudes towards people with AIDS. Supplementation with other preventive activities may be needed to achieve lasting changes in students' risk-taking behavior.

Abstract
OBJECTIVE The discriminant validity of a generic, health related quality of life (HRQL) measure, the SF-36, was compared with that of a disease specific HRQL measure, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), in patients aged 67-99 years who had undergone knee replacement surgery 2 to 7 years previously. METHODS A stratified random sample of 1750 Medicare beneficiaries was surveyed and 1193 usable responses were obtained (after adjustment for ineligible, incapacitated, and deceased individuals). Discriminant validity of scale scores common to both instruments (pain, physical functioning, and overall score) were compared. RESULTS Examination of discriminant validity, using Spearman correlations, showed that the WOMAC discriminates better among individuals with knee problems, while the SF-36 discriminates better among individuals with varying levels of self reported general health status and comorbidities. CONCLUSION These scales measure 2 distinct but important aspects of patients' health. These results support inclusion of both a generic and a disease specific HRQL measure in cross sectional studies.

Abstract
Generic and disease-specific health status instruments are commonly used to assess patients' outcomes. The hypothesis that they measure distinct but complementary aspects of patients' quality of life was tested using a sample of patients aged 67 to 99 years who had undergone knee replacement surgery 2 to 7 years previously. Patients' scores on a generic health-related quality-of-life (HRQOL) measure, the SF-36, were compared to those of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index; the WOMAC was developed specifically for patients with lower extremity arthritis, whereas the SF-36 is aimed at all conditions. A stratified sample of 1,750 Medicare beneficiaries was surveyed and an overall response rate of 80.3% achieved, resulting in 1,193 usable surveys (after adjustment for ineligible, incapacitated, and deceased individuals). The distribution of scores on the three dimensions common to both instruments (i.e., pain, physical function, and overall score) showed consistently higher scores on the WOMAC, on a scale of 0 (worst) to 100 (best), than on the SF-36, indicating less disability from arthritis than from other conditions after knee surgery in this elderly population. Statistically significant differences in the number of people with perfectly healthy scores were detected between the instruments; with regard to pain, 32.2% of the sample reported no pain due to arthritis on the WOMAC, compared with only 13.6% reporting no pain due to any conditions on the SF-36. The figures for physical function and overall score were 9.6% versus 1.4%, and 6.9% versus 0.2%, respectively. Examination for discriminant validity showed that the scores on the two scales followed hypothesized patterns: the WOMAC discriminated better among subjects with varying severity of knee problems, whereas the SF-36 discriminated better among subjects with varying levels of self-reported health status and comorbidity. The results of this study support the inclusion of both a generic and a disease-specific HRQOL measure to assess patient outcomes fully.

Abstract
Serial sera from 2 patients infected with the human immunodeficiency virus (HIV) type 1 attending a clinic in Nairobi, Kenya, and with blood cultures yielding Brucella melitensis, were tested by enzyme-linked immunosorbent assay for their serological response (Brucella-specific immunoglobulin (Ig) M and IgG) to Brucella infection. Antibody responses were comparable to those of immunocompetent individuals, one patient showing serology typical of acute brucellosis, the other of chronic brucellosis. Sera from 100 other patients, 65 of whom were HIV-positive, attending the same clinic but whose routine microbiological cultures were negative for Brucella, were tested retrospectively for Brucella-specific antibody. Eight had Brucella-specific IgM and IgG, 6 had IgM only and 21 had IgG only, suggesting relatively high levels of exposure to Brucella in the study cohort. There was no association between Brucella antibody status and HIV status. Brucellosis is probably underdiagnosed in Kenya. Brucella serology may be helpful in the diagnosis of patients with non-specific symptoms in East Africa, regardless of HIV status.

Abstract
The long latency time, without any characteristic clinical sign, of transmissible degenerative encephalopathies, the transmissibility of the called "prion" infectious agent, associated with its exceptional resistance to normal inactivation methods, are resulting in accidental transmissions, both human (Creutzfeldt-Jakob disease), and animal (bovine spongiform encephalopathy). Among data about physical and chemical inactivation methods tested, we retain, to avoid professional or iatrogenic transmissions in the laboratory or in hospital, steam autoclaving and sodium hypochlorite or hydroxide treatment. But inactivation shall not be performed using the current processes as regarding parameters such as temperature, concentration and duration of exposure.

Abstract
The aim of this prospective study was to investigate the relationship between carriage of antibiotic-resistant Staphylococcus aureus and infection with the human immunodeficiency virus (HIV). A total of 554 pernasal swabs was taken during a six-month period from 554 adult patients attending three outpatient clinics and from inpatients from a hospital in Nairobi, Kenya. Overall, 121 swabs (22%) yielded Staphylococcus aureus, there being significantly higher carriage in HIV-positive patients (71/264, 27%) than in HIV-negative patients (50/290, 17%); p = 0.008. Antimicrobial resistance rates were determined for 110 isolates and were high for penicillin (91%) and tetracycline (72%) and low for erythromycin (8%), methicillin (3%), gentamicin (5%) and chloramphenicol (0%). Genetic analysis showed plasmids in the range of 24-42 MDa to be associated with beta-lactamase production and plasmids in the range of 3-5 MDa to be associated with resistance to tetracycline, erythromycin and trimethoprim. All nine erythromycin-resistant strains were from HIV-positive patients (p = 0.02). There was a significant association of tetracycline resistance with HIV seropositivity (p = 0.002). The association of HIV seropositivity with Staphylococcus aureus carriage and carriage of antibiotic-resistant strains against the background of the HIV epidemic are of relevance in individual patient care and raise concern for public health.

Abstract
There have been conflicting reports on the effect of prior adjuvant chemotherapy on the response of advanced breast cancer to primary chemotherapy. We report a retrospective review of the outcome of chemotherapy with epirubicin 100 mg/m2 for advanced breast cancer in 39 patients who had previously received adjuvant cyclophosphamide, methotrexate and 5-fluorouracil (CMF). The response rate (complete responses plus partial responses) was 38.5%, with a median duration of response of 33 weeks. There was no significant difference in the response rate or duration of survival when these patients were compared with matched controls who had not received adjuvant chemotherapy. However, the limitations of this study were such that an adverse effect of adjuvant CMF on the response to epirubicin cannot be excluded.

Abstract
A cyclical, sequential combination of tamoxifen and megestrol acetate (group B) was compared with conventional therapy (tamoxifen alone, group A) in 261 breast cancer patients. There was no statistically significant difference between groups for overall response rate (complete+partial response: group A, 35.8%, group B, 40.8%; p = 0.505) or for median response duration in responders (group A, 128 weeks, group B, 136 weeks; p = 0.488). Median survival from randomization was longer in those patients receiving sequential therapy (group A, 90 weeks, group B, 134 weeks) with a significantly lower relative death rate (group B/group A = 0.67; p = 0.011). This survival benefit appears to be due to a delay in progression among nonresponders in the sequential therapy group.
