Computer-controlled monitoring of bladder pressure in the prevention of 'TUR syndrome': a randomized study of 53 cases.

OBJECTIVE: To evaluate the performance of a computer-controlled monitor of bladder pressure in the prevention of transurethral resection (TUR) syndrome. PATIENTS AND METHODS: The in vitro pressure loss in catheters and endoscopes of different size was measured for irrigant flow rates of 0-500 mL/min to calibrate them before surgery. The calibrations were used in a computerized monitoring system designed to control bladder pressure during TUR of the prostate (TURP). The performance of the system was assessed in a randomized study of 53 patients with a prostate adenoma or carcinoma (Group A, 27 unmonitored patients; Group B, 26 monitored patients). The primary criterion for evaluating the absorption of irrigating fluid was the level of glycine in the blood. RESULTS: When patients with capsule perforation were included in the analysis, there was no statistically significant difference in mean glycine absorption between the groups, although glycine levels were highest in Group A, particularly in those cases with perforation (four in Group A; two in Group B). When the results for patients with capsule perforation were excluded from the analysis, there was a significant difference in the incidence of irrigant absorption between the groups. The extent of absorption was not related to the duration of operation (which was shorter in Group B) nor to the weight of resection chippings. CONCLUSION: The continuous computerized monitoring of bladder pressure during TURP effectively reduced the absorption of irrigant fluid, making the procedure safer for the patient and easier for the surgeon.

[Value of three-dimensional surface reconstruction scanning in urology. Preliminary results].

The development of helicoidal CT acquisition allows 3D reconstruction of vessels, cavities or parenchyma of mobile organs such as the kidney. The value of this 3D surface reconstruction was investigated in various areas of urology: congenital malformations (horseshoe kidney, megaureter, ectopic organs), acquired malformations (diverticulum, trabeculated bladder), renal stones, particularly staghorn calculi, and renal transplantation. The fields of interest of 3D CT scans are still poorly defined, but are probably threefold: diagnostic, therapeutic and for teaching purposes. 3D representation completes classical axial scans and, in some cases, competes with other more invasive imaging techniques.

Body mass index as a discriminant function among health-related variables and risk factors.

A group of 206 subjects (30-55 years) were studied with the objective of quantifying the relationships between fitness indicators (relative body weight (BMI), aerobic power, muscular endurance), health indicators and risk factors, (appraised age, cost of health services consumed, blood pressure (SBP and DBP), blood lipids (CHO and HDL), cigarette smoking). BMI was significantly correlated with the risk indicators in the male sample (.302 less than or equal to r less than or equal to .364) and in the female sample (.217 less than or equal to r less than or equal to .521). All coefficients were in the direction of the established biological assumption as concerns hazards to health. The discriminant analysis revealed that in the total group of men, 77% (p less than or equal to .001) of the subjects could be classified either in high or low BMI (greater than Q75 or less than or equal to Q25) on the basis of the scores in SBP, HDL, HDL/CHO. In the subgroup of women greater than or equal to 40 years, statistically significant classification occurred in 100% of the cases (p less than or equal to .001) on the basis of DBP, CHO, HDL/CHO, NCIG. The results indicate that BMI is a fitness determinant which is valid, convenient and easy to use in the detection of unfavorable health indices and when clinical intervention is justified.

Chest pain: relationship of psychiatric illness to coronary arteriographic results.

Seventy-four patients with chest pain and no prior history of organic heart disease were interviewed with a structured psychiatric interview immediately after coronary arteriography. The majority of patients with both negative and positive coronary angiographies had undergone previous exercise tolerance tests, but the patients with angiographic coronary artery disease were significantly more likely to have had positive results on a treadmill test. Patients with chest pain and negative coronary arteriograms were significantly younger; more likely to be female; more apt to have a higher number of autonomic symptoms (tachycardia, dyspnea, dizziness, and paresthesias) associated with chest pain, and more likely to describe atypical chest pain. Patients with chest pain and normal coronary arteriographic results also had significantly higher psychologic scores on indices of anxiety and depression and were significantly more likely to meet criteria of the Diagnostic and Statistical Manual of Mental Disorders, third edition, for panic disorder (43 percent versus 6.5 percent), major depression (36 percent versus 4 percent), and two or more phobias (36 percent versus 15 percent) than were patients with chest pain and a coronary arteriography study demonstrating coronary artery stenosis.

Panic disorder: epidemiology in primary care.

One hundred ninety-five patients in a primary care practice were screened with the National Institute of Mental Health Diagnostic Interview Schedule, a structured psychiatric interview, so that the epidemiology of panic disorder could be studied. Thirteen percent of the patients met criteria described in the Diagnostic and Statistical Manual of Mental Disorders, ed 3 (DSM-III) for panic disorder (6.7 percent if the DSM-III exclusionary criteria are used). An additional 8.7 percent of patients, labeled in the study as having simple panic, had four or more autonomic symptoms of panic disorder but did not meet DSM-III criteria (three panic attacks in a three-week period). Compared with controls, patients with panic disorder or simple panic had a significantly higher lifetime risk of major depression, multiple phobias, and avoidance behavior and higher scores on their psychological distress scales. Patients with panic disorder and simple panic often misinterpreted their symptoms as being due to a physical illness and had significantly higher scores on the somatization scale of the SCL-90 and on a medical review of symptoms than did the controls with no panic disorder. It is important to diagnose panic disorder accurately because double-blind placebo-controlled studies have demonstrated the efficacy of psychopharmacologic treatments, including tricyclic antidepressants (notably imipramine and desipramine), the high-potency benzodiazepine (alprazolam) and monoamine oxidase inhibitors (phenelzine). Primary care physicians, by screening patients with complaints of tension and anxiety, as well as multiple unexplained somatic complaints for panic disorder, may be able to reduce somatic preoccupation and disease phobia by instituting effective therapy.

Grandfather - granddaughter incest: a trigenerational view.

Grandfather-granddaughter incest accounts for about 10% of all reported cases of intrafamilial childhood sexual abuse. In a sample of 10 such cases, all referrals came from mothers of the child victims; six of these mothers had themselves been abused in childhood by the perpetrator. For eight of the 10 perpetrators, multiple child sexual victims were identified in a pattern that suggests facultative pedophilia. Only two of the 18 grandchildren sexually abused by the 10 grandfathers were asymptomatic at the time of report. Grandchild victims from chaotic families showed educational and behavioral symptoms; those from stable families exhibited fears and phobias. Eight of the 18 grandchildren were victimized by multiple perpetrators. The results cast doubt on the assumption that grandparent incest is a benign form of abuse and indicate that there is some justification for the fears expressed by adult incest victims about visitation between their children and the father-perpetrator.
