RESUMEN
PURPOSE: The aim of the present study is to investigate the impact of the near-infrared (NIRF) technology with indocyanine green (ICG) in robotic urologic surgery by performing a systematic literature review and to provide evidence-based expert recommendations on best practices in this field. METHODS: All English language publications on NIRF/ICG-guided robotic urologic procedures were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement to evaluate PubMed®, Scopus® and Web of Science™ databases (up to April 2019). Experts in the field provided detailed pictures and intraoperative video-clips of different NIRF/ICG-guided robotic surgeries with recommendations for each procedure. A unique QRcode was generated and linked to each underlying video-clip. This new exclusive feature makes the present the first "dynamic paper" that merges text and figure description with their own video providing readers an innovative, immersive, high-quality and user-friendly experience. RESULTS: Our electronic search identified a total of 576 papers. Of these, 36 studies included in the present systematic review reporting the use of NIRF/ICG in robotic partial nephrectomy (n = 13), robotic radical prostatectomy and lymphadenectomy (n = 7), robotic ureteral re-implantation and reconstruction (n = 5), robotic adrenalectomy (n = 4), robotic radical cystectomy (n = 3), penectomy and robotic inguinal lymphadenectomy (n = 2), robotic simple prostatectomy (n = 1), robotic kidney transplantation (n = 1) and robotic sacrocolpopexy (n = 1). CONCLUSION: NIRF/ICG technology has now emerged as a safe, feasible and useful tool that may facilitate urologic robotic surgery. It has been shown to improve the identification of key anatomical landmarks and pathological structures for oncological and non-oncological procedures. Level of evidence is predominantly low. Larger series with longer follow-up are needed, especially in assessing the quality of the nodal dissection and the feasibility of the identification of sentinel nodes and the impact of these novel technologies on long-term oncological and functional outcomes.

PURPOSE: To establish consensus on follow-up (FU) after focal therapy (FT) in renal masses. To formulate recommendations to aid in clinical practice and research. METHODS: Key topics and questions for consensus were identified from a systematic literature research. A Web-based questionnaire was distributed among participants selected based on their contribution to the literature and/or known expertise. Three rounds according to the Delphi method were performed online. Final discussion was conducted during the "8th International Symposium on Focal Therapy and Imaging in Prostate and Kidney Cancer" among an international multidisciplinary expert panel. RESULTS: Sixty-two participants completed all three rounds of the online questionnaire. The panel recommended a minimum follow-up of 5 years, preferably extended to 10 years. The first FU was recommended at 3 months, with at least two imaging studies in the first year. Imaging was recommended biannually during the second year and annually thereafter. The panel recommended FU by means of CT scan with slice thickness ≤3 mm (at least three phases with excretory phase if suspicion of collecting system involvement) or mpMRI. Annual checkup for pulmonary metastasis by CT thorax was advised. Outside study protocols, biopsy during follow-up should only be performed in case of suspicion of residual/persistent disease or radiological recurrence. CONCLUSIONS: The consensus led to clear FU recommendations after FT of renal masses supported by a multidisciplinary expert panel. In spite of the low level of evidence, these recommendations can guide clinicians and create uniformity in the follow-up practice and for clinical research purposes.

HIV-infected prisoners face an inordinate number of community re-entry challenges. In 2007, 102 HIV-infected prisoners in Malaysia were surveyed anonymously within six months prior to release to assess the prevalence and correlates of community re-entry challenges. Staying out of prison (60.8%), remaining off drugs (39.2%), finding employment (35.3%) and obtaining HIV care (32.4%) were the re-entry challenges reported most frequently. Global stigma, negative self-image and public attitudes-related stigma were independently associated with challenges to obtaining HIV care. In multivariate analyses, those with previous incarcerations (adjusted odds ratio [AOR], 3.2; 95% confidence interval [CI], 1.4-7.6), higher HIV-related symptoms (AOR, 2.0; 95% CI, 1.0-4.1) and higher public attitudes-related stigma (AOR, 2.5; 95% CI, 1.2-5.1) had a significantly higher likelihood of identifying more re-entry challenges. Targeted interventions, such as effective drug treatment, HIV care and public awareness campaigns, are crucial for stemming the HIV epidemic and improving health outcomes among HIV-infected prisoners in Malaysia.

The usual terrible triad of the elbow consists of posterior dislocation of the elbow, radial head fracture and coronoid fracture. We describe a new variant of the terrible triad of the elbow consisting of fracture of the capitellum involving the full length of the trochlea and posterolateral dislocation of the elbow associated with coronoid fracture (type 1 Regan-Morrey). A 25-year-old girl was brought to the emergency ward with the history of having jumped from the third floor with an intention of committing suicide. She sustained multiple fractures, i.e, fracture ribs, bilateral intra-articular fracture of the lower end of the radius, left-side elbow injury, left subtrochanteric fracture femur and left zygomatic fracture with head injury. The elbow was stable after stabilization of the capitellum fracture through a collateral approach. Coronoid fragment was left alone, as it was a very small fragment.

UNLABELLED: (i) AIM OF THE STUDY: The study was carried out with the aim to evaluate a polymerase chain reaction (PCR) based on the amplication of a 169 bp DNA fragment specific for the Mycobacterium tuberculosis complex for the rapid diagnosis of tuberculous meningitis (TBM). (ii) METHODOLOGY: A total of 105 CSF specimens from clinically suspected cases of TBM were studied. Clinical details of the cases and cytochemical parameters of the CSF specimens were recorded. In addition to the 105 specimens, 10 CSF specimens from cases other than TBM, 4 non-mycobacterial culture isolates (1 strain of E. coli, 1 strain of Proteus species and 2 strains of Salmonella species) and 1 sample of sterile distilled water were processed as negative controls. For positive control standard culture of Mycobacterium tuberculosis H37Rv was processed with every batch of specimens. Besides PCR, smear for AFB by the Ziehl Neelsen Carbol Fuchsin (ZNCF) and the fluoro chrome method and culture on LJ medium was also carried out. (iii) RESULTS: By PCR, 31.42% specimens were found positive, whereas by conventional culture on LJ medium only 3.8% specimens were positive. Only 1.9% specimens were found to be smear positive by the fluorochrome staining method, while none was positive by the ZNCF method. The PCR results showed complete correlation with the clinical findings of the patients. (iv) CONCLUSION: The PCR was found to be superior to the currently available techniques for the diagnosis of tuberculous meningitis in terms of sensitivity, specificity and rapidity and could play a critical role in the diagnosis of suspected cases.

OBJECTIVE: Functional status measures are potent independent predictors of hospital outcomes and mortality. The study objective was to compare medical record with interview data for functional status. SUBJECTS AND METHODS: Subjects were 525 medical patients, aged 70 years or older, hospitalized at an academic medical center. Patient interviews determined status for 7 basic activities of daily living (BADLs) and 7 instrumental activities of daily living (IADLs). Medical records were reviewed to assess documentation of BADLs and IADLs. RESULTS: Most medical records contained no documentation of individual BADLs and IADLs (61% to 98% of records lacking documentation), with the exception of walking (24% of medical records lacking documentation). Impairment prevalence was lower in medical records than at interview for all BADLs and IADLs, and agreement between interview and medical record was poor (kappa < 0.40 for individual BADLs and IADLs). Sensitivity of the medical record for BADL and IADL impairment was poor (range 95% to 44%), using the interview as a reference standard. Sensitivity and specificity of the medical record for detection of BADL and IADL impairment changed substantially when records with nondocumentation of functional status were excluded or were assumed to be equivalent to independence. CONCLUSIONS: The results suggest that the medical record is a poor source of data on many functional status measures, and that assuming that nondocumentation of functional status is equivalent to independence may be unwarranted. Given the prognostic importance of functional status measures, the results highlight the importance of developing reliable and efficient means of obtaining functional status information on hospitalized older patients.

OBJECTIVE: To evaluate the role of child care centers in a community-wide hepatitis A epidemic. METHODS: We analyzed surveillance data during an epidemic in Maricopa County, Arizona, from January to October 1997 and conducted a case-control study using a sample of cases reported from June to November. Cases were physician-diagnosed and laboratory confirmed; control subjects were frequency matched by age and neighborhood. Information regarding hepatitis A risk factors, including child care-related exposures, was collected. Characteristics of all licensed child care centers in the county were obtained through review of computerized lists from the Arizona Office of Child Day Care Licensing. Surveillance data were linked to the child care list to determine which centers had reported hepatitis A cases. We conducted univariate and multivariate conditional logistic analyses and calculated population attributable risks (PAR). RESULTS: In total, 1242 cases (50/100 000 population) were reported. The highest rates occurred among people aged 0 to 4 (76/100 000), 5 to 14 (95/100 000), and 15 to 29 (79/100 000) years. The most frequently reported risk factor was contact with a hepatitis A patient (45%). However, nearly 80% of these contacts were with individuals who attended or worked in a child care center. Overall, child care center-related contact could have been the source of infection for 34% of case-patients. In the case-control study, case-patients (n = 116) and control subjects (n = 116) did not differ with respect to demographic characteristics. A total of 51% of case-patients compared with 18% of control subjects reported attending or working in a child care setting (direct contact; adjusted odds ratio [OR]: 6.0; 95% confidence interval [CI]: 2.1-23.0) or being a household contact of such a person (indirect contact; OR: 3.0; 95% CI: 1.3-8.0). In age-stratified analyses, the association between hepatitis A and direct or indirect contact with child care settings was strongest for children <6 years old and adults aged 18 to 34 years. Household contact with a person with hepatitis A also was associated with hepatitis A (OR: 9.2; 95% CI: 2.6-58.2). The presence of a child <5 years old in the household was not associated with hepatitis A. The estimated PAR for direct child care contact was 23% (95% CI: 16-34), for indirect child care contact was 21% (95% CI: 13-35), and for any child care contact was 40% (95% CI: 30-53). Information on 1243 licensed child care centers was obtained, with capacity ranging from 5 to 479 slots (mean: 87). Thirty-four (2.7%) centers reported hepatitis A cases. Centers that had a mean capacity of >50 children were more than twice as likely to have had a reported case of hepatitis A (OR: 2.6; 95% CI: 1.1-6.7). Among the 747 centers that accepted >50 children, having infant (OR: 3.7; 95% CI: 1.6-8.3), toddler (OR: 6.3; 95% CI: 2.2-20.0), or full-day service (OR; undefined; 95% CI: 1.7- ~) was associated with having a reported case of hepatitis A. CONCLUSIONS: In Maricopa County, people associated with child care settings are at increased risk of hepatitis A, and child care attendees may be an appropriate target group for hepatitis A vaccination. Considering the estimated proportion of children who attended child care and were old enough to receive hepatitis A vaccine (>/=2 years of age) and the calculated PAR, approximately 40% of cases might have been prevented if child care center attendees and staff had been vaccinated. However, epidemiologic studies indicate that the proportion of cases that are attributable to child care center exposure varies considerably among counties, suggesting that this exposure may be associated with an increased risk of hepatitis A in some communities but not in others. To prevent and control hepatitis A epidemics in communities, the Advisory Committee on Immunization Practices and the American Academy of Pediatrics have adopted a long-term strategy of routine vaccination of children who live in areas with consistently elevated hepatitis A rates. After demonstrating cost-effectiveness, a rule was implemented in January 1999 to require hepatitis A vaccination of all children who are aged 2 to 5 years and enrolled in a licensed child care facility in Maricopa County. Other communities with similar epidemiologic features might consider routine vaccination of child care center attendees as a long-term hepatitis A prevention strategy. Consistent with current recommendations, in communities with persistently elevated hepatitis A rates where child care center attendance does not play an important role in hepatitis A virus transmission in the community, child care centers may nonetheless provide a convenient access point for delivering hepatitis A as well as other routine childhood vaccinations.

OBJECTIVES: To evaluate the renal function and blood pressure outcomes after laparoscopic renal cryotherapy. Laparoscopic renal cryoablation is a developmental minimally invasive modality for the treatment of renal neoplasms. After cryotherapy, a segment of renal parenchyma is rendered ischemic/necrotic and left in situ. It is currently unknown whether this may trigger renin overproduction and thus renin-mediated hypertension. METHODS: Data are presented for 22 of 56 treated patients, each of whom completed a minimum follow-up of 6 months. The data were obtained from patient charts, phone interviews, and/or questionnaires. These results were statistically compared over time by paired t tests. RESULTS: The mean follow-up was 20.6 months. No significant differences were found between the preoperative and most recent postoperative serum creatinine (sCr) levels (1.13 and 0.91 mg/dL, respectively), systolic and diastolic blood pressure values (135.6 versus 131.2 mm Hg and 78 versus 72.7 mm Hg, respectively), or in the estimated creatinine clearance (P <0.05). The number or dose of antihypertensive medications did not change during the follow-up period for any patient. In 3 patients with a solitary kidney, the blood pressure and sCr values remained unchanged (mean preoperative sCr 1.43 mg/dL and mean postoperative sCr after a minimum of 6 months 1.33 mg/dL). CONCLUSIONS: Laparoscopic renal cryoablation did not have a deleterious impact on renal function or blood pressure during a mean follow-up of 20.6 months.

BACKGROUND: Restricted activity is a potentially important indicator of health and functional status. Yet, relatively little is known about the incidence, precipitants, or health care utilization associated with restricted activity among older persons. OBJECTIVE: To more accurately estimate the rate of restricted activity among community-living older persons, to identify the health-related and non-health-related problems that lead to restricted activity, and to determine whether restricted activity is associated with increased health care utilization. DESIGN: Prospective cohort study. SETTING: New Haven, Connecticut. PARTICIPANTS: 754 nondisabled members of a large health plan, 70 years of age or older, who were categorized according to their risk for disability (low, intermediate, or high). MEASUREMENTS: Occurrence of restricted activity (defined as having stayed in bed for at least half a day or having cut down on one's usual activities because of an illness, injury, or another problem), problems leading to restricted activity, and health care utilization were ascertained during monthly telephone interviews for up to 2 years. RESULTS: In median follow-up of 15 months, 76.6% of participants reported restricted activity during at least 1 month and 39.3% reported restricted activity during 2 consecutive months. The rates of restricted activity per 100 person-months were 19.0 episodes for all participants and 16.9, 27.3, and 22.7 episodes for participants at low, intermediate, and high risk for disability, respectively. Of the 24 prespecified health-related and non-health-related problems, the rates per 100 person-months of restricted activity ranged from 0.1 episode for "problem with alcohol" to 65.5 episodes for "been fatigued." On average, participants identified 4.5 different problems as a cause for their restricted activity. Health care utilization was substantially greater during months with restricted activity than months without restricted activity. The corresponding rates per 100 person-months were 63.8 and 45.1 for physician office visits, 12.5 and 1.0 for emergency department visits, 14.1 and 0.3 for hospital admissions, and 67.6 and 45.1 for any health care utilization (P < 0.001 for each pairwise comparison). CONCLUSIONS: Restricted activity is common among community-living older persons, regardless of risk for disability, and it is usually attributable to several concurrent health-related problems. Although restricted activity is associated with a substantial increase in health care utilization, older persons with restricted activity often do not seek medical attention.

BACKGROUND AND PURPOSE: Orthotopic ileal neobladder is currently the preferred continent urinary diversion in suitable patients undergoing radical cystectomy for muscle-invasive bladder cancer. To our knowledge, presented herein is the initial report of laparoscopic orthotopic ileal neobladder following cystectomy that was performed completely intracorporeally in a porcine model. MATERIALS AND METHODS: The laparoscopic technique was developed in seven pigs. Subsequently, a long-term survival study was performed in 12 consecutive animals. Laparoscopic cystectomy was performed, preserving the urethral sphincter. An ileal segment of 35 cm (first three animals), 45 cm (next four), or 55 cm (final five animals) with adequate mesentery was isolated; and ileal continuity was restored intracorporeally by a stapled anastomosis. Ileal detubularization for construction of an ileal neobladder, urethroileal anastomosis, and bilateral stented ileoureteral anastomoses to a tubular Studer limb extension were all created completely intracorporeally using only laparoscopic free-hand suturing and knot-tying. Biochemical data (preoperative and serial postoperative hemoglobin, renal panel, blood gases), radiologic studies (intravenous urogram, retrograde pouchgram), functional measures (neobladder urodynamics, Whitaker pressure-flow study of both ureters), and microscopic evaluation of the neobladder and ureteroileal and urethroileal anastomotic sites were obtained to evaluate the long-term functional and anatomic outcome. RESULTS: Completely intracorporeal laparoscopic construction of an ileal orthotopic neobladder was successful in all 12 animals without intraoperative or early postoperative complications or open conversion. The mean operating time was 5.4 hours (range 4.5-6.5 hours), and the blood loss was minimal. All study pigs survived their predetermined follow-up period, ranging from 1 to 3 months. Late complications occurred in three animals: one port-site abscess and two cases of E. coli pyelonephritis and azotemia, leading to one death at 2 months. The mean serum creatinine concentrations were 1.33 mg/dL, 1.61 mg/dL, and 1.55 mg/dL at 1, 2, and 3 months, respectively. The mean neobladder capacity was 420 mL (range 250-700 mL) with pressures < or = 20 cm H2O (range 17-20 cm H2O). Pre-euthanasia Whitaker testing confirmed excellent drainage in all 24 ureters. No ileoureteral or ileourethral anastomotic strictures or leaks were noted on intravenous urography, retrograde pouchgram, or postmortem physical calibration of the anastomotic sites. Histologic examination confirmed excellent healing without obvious fibrosis. CONCLUSION: Laparoscopic construction of an orthotopic neobladder is feasible. The anatomic and functional outcome is excellent and comparable to that of open surgery. Clinical application is imminent.

PURPOSE: This study examined the prevalence, correlates, and negative consequences of unmet need for personal assistance with activities of daily living (ADLs) among older adults. DESIGN AND METHODS: The authors analyzed cross-sectional data from the 1994 National Health Interview Survey's Supplement on Aging. Data were weighted to be representative of the noninstitutionalized population aged 70 years and older. RESULTS: Overall, 20.7% of those needing help to perform 1 or more ADLs (an estimated 629,000 persons) reported receiving inadequate assistance; for individual ADLs, the prevalence of unmet need ranged from 10.2% (eating) to 20.1% (transferring). The likelihood of having 1 or more unmet needs was associated with lower household income, multiple ADL difficulties, and living alone. Nearly half of those with unmet needs reported experiencing a negative consequence (e.g., unable to eat when hungry) as a result of their unmet need. IMPLICATIONS: Greater, targeted efforts are needed to reduce the prevalence and consequences of unmet need for ADL assistance in elderly persons.

Few studies have addressed the accuracy of self-reported cancer history, although epidemiologic studies routinely use self-reported information as the sole source of exposure or outcome data or as a criterion for exclusion from study participation. In this paper, false-negative reporting of cancer history is examined in a community-based sample by comparing interview data with tumor registry records. Subjects were participants in the 1980 New Haven Epidemiologic Catchment Area study; in 1995, cancer records (from 1935 onward) were obtained by linking the sample to the Connecticut Tumor Registry. Analyses focused on 263 individuals who had at least one tumor reported to the Connecticut Tumor Registry prior to participation in the Epidemiologic Catchment Area study. The overall rate of false-negative reporting was 39.2%. Logistic regression analysis revealed that false-negative reporting was significantly associated with non-White race, older age, increased time since cancer diagnosis, number of previous tumors, and type of cancer treatment received. In addition, false-negative reporting varied widely by cancer site, ranging from 0% for melanoma skin cancer to 83.3% for central nervous system cancers. The false-negative rate for breast cancer was 20.8%, that for colon and prostate cancers was 42.1%, and that for bladder cancer was 61.5%. Implications of these findings for prevalence estimation and future epidemiologic studies are discussed.

An exponential increase has occurred in the use of laparoscopic surgery in patients who have undergone prior renal transplantation. The main indications are the treatment of symptomatic pelvic lymphoceles and native kidney nephrectomy for various reasons. Most reports have shown laparoscopy to be equally effective and less morbid than conventional open surgery. In addition to conferring the benefits of a minimally invasive approach, laparoscopy potentially offers three advantages specific to this immunosuppressed population of patients. First, it avoids the potential wound-related problems inherent in open surgery. Second, by reducing hospitalization, it reduces the risk for nosocomial infections. Third, by allowing an earlier resumption of oral intake, it enables the continuation of oral immunosuppression. Proper perioperative management of fluid and electrolyte balance is critical in this group of patients. Despite concerns, there is no evidence showing that laparoscopy adversely affects allograft function.

OBJECTIVES: Development of small animal models for laparoscopic surgery is important for basic pathophysiologic and oncologic studies, instrument development, and surgical training. Although transperitoneal laparoscopy has been described in the rat, the technical feasibility of the retroperitoneoscopic approach for major renal surgery has not been reported previously. Herein, we describe the development of a rat model for retroperitoneal minilaparoscopic nephrectomy. METHODS: Sixteen male Sprague-Dawley rats underwent a three-port bilateral retroperitoneoscopic nephrectomy using 2 and 3-mm instruments and optics exclusively. After developing the technique in 10 animals, the study was conducted in 6 animals. Following retroperitoneal balloon dilation and CO(2) pneumoretroperitoneum (mean 4.5 mm Hg), nephrectomy was accomplished by intracorporeal en bloc ligation of the renal pedicle. To prevent peritoneal entry, the anterior surface of the kidney was mobilized subcapsularly. Volume of the created retroperitoneal space and peritoneal integrity were confirmed by a contrast x-ray study. Intraperitoneal pressure was monitored constantly during the procedure. RESULTS: Mean surgical time was 74.5 minutes (range 60 to 95) and estimated blood loss was less than 1 mL. Mean volume of the retroperitoneal space was 8.4 mL after initial balloon dilation, and 11.5 mL after nephrectomy. Mean weight of the excised kidneys was 1. 4 g. Inadvertent peritoneotomy occurred during 3 of 12 study nephrectomies. Complications included renal artery hemorrhage leading to death in 1 animal and renal vein injury in 1 animal. CONCLUSIONS: Laparoscopic retroperitoneal nephrectomy in the rat model is technically feasible. This novel small animal model can be used for further studies of the retroperitoneal laparoscopic approach.

The population abundance of Phlebotomus argentipes Annandale & Brunetti was studied between January 1986 and December 1987 at 2 sites in West Bengal, India, in relation to 8 ecological parameters (air temperature, rainfall, windspeed, relative humidity, soil moisture, soil temperature, soil pH, and soil organic carbon). Sand flies were present throughout the year with minimum abundance in winter months and maximum during monsoon and postmonsoon months. Correlation analysis examined pairwise relationships among the 8 ecological parameters and P. argentipes abundance. Multiple linear regression of sand fly abundance on the 8 parameters showed that average soil temperature and soil moisture, both recorded 1 mo earlier, were associated positively with sand fly abundance. These findings have important implications for Indian kala-azar disease control and prevention. Effective vector management programs are needed most when weather conditions favor increased sand fly abundance, given that greater sand fly abundance increases the likelihood of host-vector contact and the transmission of Leishmania.

BACKGROUND AND OBJECTIVES: Benign prostatic hyperplasia (BPH) is not the only cause of lower urinary tract symptoms (LUTS) in elderly men. Thus, routine use of invasive measures to debulk the prostate will produce suboptimal treatment outcomes in many patients. We attempted to determine whether two parameters based on transrectal ultrasonography could accurately determine the presence of obstruction and predict the response to therapy. PATIENTS AND METHODS: In the first part of the study, the presumed circle area ratio (PCAR) and transitional zone area ratio (TZAR) were determined in 86 men aged 50 years or greater and correlated with the patient's age, International Prostate Symptom Score (IPSS), and peak flow rate Qmax. The ability of cut-off values of PCAR = 0.75 and TZAR = 0.5 to stratify patients for the presence of obstruction was determined. In the second part of the study, PCAR and TZAR were determined in 25 men in urinary retention, who were further classified as having high voiding pressure (Group A) or an underactive detrusor muscle (Group B). Obstruction was reassessed immediately and 1 month after transurethral resection (TURP), and the ability of PCAR and TZAR to predict treatment outcome was assessed. RESULTS: Both PCAR and TZAR showed weak correlations with IPSS and a moderate inverse correlation with Qmax. The cut-off values were able to separate patients according to Qmax and overall obstructive states. A PCAR of > or = 0.75 or a TZAR of > or = 0.5 would have predicted obstruction in 34 of 36 obstructed patients, and lower values would have correctly predicted the absence of obstruction in 33 of 37 patients. In patients with high voiding pressure, all those with PCAR and TZAR values above the cut-off showed good to average improvement after TURP. In patients with an underactive detrusor, both PCAR and TZAR were extremely useful in predicting the response to TURP. CONCLUSION: In view of the morbidity and mortality of invasive treatments for BPH, subjecting patients with LUTS to these treatments in the absence of obstruction is irrational. We recommend the use of transrectal ultrasonography measures in the routine evaluation of BPH and reserve the more invasive urodynamic studies for patients with discrepant findings. Further studies in a larger group of patients are needed.

OBJECTIVE: To examine the longitudinal effects of major depression and phobia on stage at diagnosis of subsequent breast cancer. METHOD: Data from the New Haven Epidemiologic Catchment Area (ECA) study were linked to the Connecticut Tumor Registry (CTR). The sample comprised of seventy-two women with a first primary breast cancer diagnosed sometime after their baseline ECA study interview. In the ECA study, lifetime psychiatric history was assessed using the Diagnostic Interview Schedule based on DSM-III criteria. Stage at diagnosis of breast cancer was taken from CTR records and dichotomized into early stage (in situ and localized tumors) versus late stage (regional and distant tumors). RESULTS: A positive history of major depression was associated with an increased likelihood of late-stage diagnosis of breast cancer (odds ratio [OR] = 9.81, p = 0.039), whereas a positive history of phobic disorders was associated with a decreased likelihood of late-stage diagnosis (OR = 0.01, p = 0.021), controlling for sociodemographic characteristics of the sample. CONCLUSIONS: These analyses revealed a longitudinal association between reported lifetime psychiatric history and stage at diagnosis of subsequent breast cancer. Phobia may motivate women to adhere to breast cancer screening recommendations and to report suspicious symptoms to a physician without delay. Major depression, on the other hand, was identified as an important predictor of late-stage diagnosis; proper recognition and management of depression in the primary care setting may have important implications for breast cancer detection and survival.

PROBLEM/CONDITION: During the twenty first century, growth in the number of older adults (persons aged > or =65 years) in the United States will produce an unprecedented increase in the number of persons at risk for costly age-associated chronic diseases and other health conditions and injuries. REPORTING PERIOD: 1995-1996. DESCRIPTION OF SYSTEMS: This report uses data from CDC's National Center for Health Statistics (NCHS) to report on leading causes of death in 1996 (from the National Vital Statistics System), major causes of hospitalization (1996 National Hospital Discharge Survey [NHDSI), and major chronic conditions (1995 National Health Interview Survey [NHIS]). The National Vital Statistics System compiles information regarding all death certificates filed in the United States. NHDS is an annual probability sample of discharges from nonfederal, short-stay hospitals. NHIS is an ongoing annual cross-sectional household survey of the U.S. civilian, noninstitutionalized population. In addition, health-care expenditures for older adults are examined by using information obtained from published reports from the U.S. Health Care Financing Administration (HCFA) and health-services literature. RESULTS: The leading causes of death among adults aged > or =65 years were heart disease (1,808 deaths/100,000 population), malignant neoplasms (1,131/100,000), and cerebrovascular disease (415/100,000). Several leading causes of mortality among older adults differed by race, with deaths caused by Alzheimer's disease more frequent among whites and deaths caused by diabetes, kidney diseases, septicemia, and hypertension more frequent among blacks. Rates of hospitalization and length of hospital stays increased with age. Hospitalizations for heart disease represented the highest proportion of all discharges among older adults (23%). Discharge rates for malignant neoplasms, stroke, and pneumonia were similar for adults aged > or =65 years and, as with heart disease, were higher for men than for women. However, the rate of hospitalization for fractures among women exceeded the rate among men. Arthritis was the most prevalent chronic condition among adults aged > or =65 years (48.9/100 adults), followed by hypertension (40.3/100) and heart disease (28.6/100). In 1995, adults aged > or =65 years comprised 13% of the population but accounted for 35% of total personal health care dollars spent ($310 billion), and real per capita personal health-care expenditure for this age group increased at an average annual rate of 5.8% during 1985-1995. Projections for future medical expenditures for older adults vary; however, all project substantial increases after the year 2000. Hip fracture, dementia, and urinary incontinence are discussed as examples of prevalent and costly health conditions among older adults that differ in potential for prevention. These conditions were selected because they result in substantial medical and social costs and they differ in potential for prevention. INTERPRETATION: The higher prevalence of serious and costly health conditions among adults aged > or =65 years highlights the importance of implementing preventive health measures in this population. PUBLIC HEALTH ACTIONS: Data regarding causes of morbidity, mortality, and health-care expenditures among older adults provide information for measuring the effectiveness of public health efforts to reduce modifiable risk factors for morbidity and mortality in this population.
