Dorsal genital nerve stimulation in patients with detrusor overactivity: a systematic review.

This study evaluates the outcome of trials to stimulate the dorsal genital nerve (DGN) in patients with lower urinary tract dysfunction. The aim of most studies was to suppress detrusor overactivity in patients with overactive bladder (OAB) syndrome by DGN stimulation. A literature search was performed using Pub Med, Web of Science, and Scopus databases (1980 to April 2012) for clinical trials of DGN stimulation in patients with detrusor overactivity. Seventeen studies were found in the literature. In the studies, different patterns of DGN stimulation were applied. The patterns were either continuous, conditional, or semi-conditional; on an acute or on a chronic basis. DGN stimulation lead to improvement of bladder capacity and reduction in urgency and/or incontinence episodes in many patients. The outcomes of conditional stimulation were comparable to continuous stimulation with respect to improvement of bladder capacity. The publications give evidence that DGN stimulation increases bladder capacity and suppresses involuntary detrusor contractions. Implantable DGN stimulation electrodes can open the way for more prolonged studies in larger patient groups to assess the effectiveness of chronic DGN stimulation in patients with OAB syndrome. Chronic DGN stimulation seems to be of value in the management of OAB syndrome.

Non-invasive techniques in the diagnosis of bladder storage disorders.

AIMS: To review clinical studies thus have been conducted to develop non-invasive diagnostic tools in the storage phase of the micturition cycle. METHODS: Pub Med and Web of Science searches were carried out. The search covered the published data of non-invasive diagnostic techniques for detrusor overactivity (DO) and/or low compliance bladder in patients with urinary storage symptoms. The patho-physiological and clinical relevance of these methods were addressed. Diagnostic accuracy of these techniques was scrutinized. RESULTS: Eighteen studies were included in the review. Ultrasonography and biomarkers were the most investigated techniques in the diagnosis of storage disorders. Assessment of diagnostic accuracy was possible in four studies. The heterogeneity in data reporting was too high to conduct a meta-analysis. Ultrasonographic parameters and cut-off values have been developed to define DO; such as bladder wall thickness (BWT), detrusor wall thickness and bladder weight. The likelihood ratio of vaginal ultrasonography in measurement of BWT was good. Guidelines are currently developing to standardize the methodologies applied in these techniques. Laboratory biomarkers of DO are gaining more attention recently, but their specificity for DO should be carefully defined. Near infrared spectroscopy (NIRS) is potential non-invasive diagnostic method that is able to detect the DO episodes in real time. However, a solution needs to be found for motion artifacts in this technique. CONCLUSION: Non-invasive diagnostic techniques for storage disorders show limited progress with some limitations. Yet these techniques still cannot replace the standard filling cystometry in standard clinical practice.

Low-radiation-dose dual-phase MDCT protocol with split contrast media dose and time optimization: protocol design for renal donors evaluation.

BACKGROUND: A routine, multiphase, computed tomography (CT) protocol is associated with high radiation exposure to potential kidney donors. To reduce radiation exposure, several authors have suggested a reduction in the number of phases. PURPOSE: To evaluate a low-radiation-dose, dual-phase protocol (i.e. a protocol with an unenhanced phase and combined vascular and excretory phase) for the preoperative evaluation of potential renal donors. MATERIAL AND METHODS: Sixty-five potential renal donors were divided into two groups. The first group was scanned with a routine quadric-phase protocol (non-contrast, arterial, venous, and delayed), and the second group was scanned with a triple-phase protocol (dual phase protocol + venous phase). In the second group, we replaced CT angiography with a routine abdominal CT technique. In addition to the evaluation of renal arteries, veins, and excretory systems, the radiation dose of the suggested protocol was compared to that of the routine quadric-phase protocol. RESULTS: The suggested protocol was efficient in the evaluation of renal arteries, veins, and excretory systems in all studied potential renal donors. Renal arteries were well visualized in the combined vascular excretory phase using the routine abdominal CT technique; no significant difference was noted when these results were compared to those obtained from the CT angiography used in the quadric-phase protocol. The mean effective radiation dose of our suggested dual-phase protocol was only 34% of the dose resulting from the routine quadric-phase protocol. CONCLUSION: Use of a low-radiation, dual-phase, CT protocol, which relied on both an unenhanced phase and a combined vascular and excretory phase, significantly reduced radiation dose. Furthermore, the proposed protocol provides adequate visualization of renal arteries and veins, and affords sufficient opacification of the urinary tract using improved acquisition triggering.

Feasibility of noninvasive near-infrared spectroscopy to diagnose detrusor overactivity.

INTRODUCTION: Near-infrared spectroscopy (NIRS) is an optical technology able to detect the hemodynamic changes in biological tissues. Our objective was to determine the feasibility of applying NIRS in the noninvasive diagnosis of detrusor overactivity (DO). PATIENTS AND METHODS: Comparative analysis was performed on 39 involuntary detrusor contractions (IDC) from 23 filling cystometries with simultaneous noninvasive NIRS of the bladder in 14 patients with DO. Motion artifacts were checked for via surface EMG of the abdominal muscles. RESULTS: Thirty-nine IDC were obtained. The median amplitude of rise in detrusor pressure at DO was 48 cm H(2)O (range: 5-219). The median filling volume at DO was 148 ml (range: 9-531). NIRS curves demonstrated apparently significant deviations from baseline in 35 of 39 (90%) DO episodes. All onsets of NIRS deviations occurred within the time period of the IDC with a mean delay of 3 s (range: 0-9). CONCLUSION: NIRS can be a potential tool for the noninvasive diagnosis of DO.

Scrotal ultrasonographic findings in obese infertile patients and their correlations to semen and hormonal profile.

OBJECTIVE: The aim of this prospective study was to compare scrotal ultrasonographic findings in obese and normal weight infertile men and correlate these findings with semen parameters and hormonal profile. MATERIAL AND METHODS: A total of 188 men presented for infertility evaluation were included in this study. They were divided according to body mass indices into obese (n=96) and normal weight infertile patients (n=92). Basic infertility evaluation, semen analysis and scrotal duplex ultrasound examination in addition to measurement of serum levels of follicular stimulating hormone, testosterone and estradiol were done for all cases. The ratio between testicular size measured by scrotal ultrasound and body mass index were calculated. RESULTS: Any significant differences were not observed in semen parameters, serum levels of follicular stimulating hormone and testosterone between obese and normal weight infertile men (p>0.05). Serum estradiol level was significantly higher in obese than normal weight infertile men (p<0.001). There is significant increase in subclinical varicocele, hydrocele and testicular microlithiasis detected by scrotal ultrasound in obese infertile men than nonobese patients (p<0.05). Despite having comparable testicular size detected on scrotal ultrasound, infertile obese men had significantly lower total testicular volume to body mass index ratio and this ratio correlated positively with semen volume, sperm concentration, total sperm count and serum testosterone but negatively with serum follicular stimulating hormone and estradiol levels. CONCLUSION: We therefore conclude that the incidence of subclinical varicocele, hydrocele and testicular microlithiasis was higher in obese infertile patients and the ratio between testicular volume assessed by scrotal ultrasound and body mass index may be a new parameter that correlates with subfertility status in these men.

Subject-Controlled, On-demand, Dorsal Genital Nerve Stimulation to Treat Urgency Urinary Incontinence; a Pilot.

OBJECTIVES: To evaluate the effect of subject-controlled, on-demand, dorsal genital nerve (DGN) stimulation on non-neurogenic urgency urinary incontinence (UUI) in a domestic setting. MATERIALS AND METHODS: Non-neurogenic patients >18 years with overactive bladder symptoms and UUI were included. Exclusion criteria were mainly stress urinary incontinence. Patients underwent 1 week of subject-controlled, on-demand, DGN stimulation, delivered by a percutaneously placed electrode near the DGN connected to an external stimulator (pulse-rate 20 Hz, pulse-width 300 µs). Patients activated the stimulator when feeling the urge to void and stimulated for 30 s. The amplitude was set at the highest tolerable level. A bladder diary including a severity score of the UUI episodes/void (scores: 0 = none, 1 = drops, 2 = dashes, 3 = soaks) and a padtest was kept 3 days prior to, during, and 3 days after the test period. The subjective improvement was also scored. RESULTS: Seven patients (4 males/3 females) were enrolled, the mean age was 55 years (range 23-73). Six completed the test week. In the remaining patient the electrode migrated and was removed. 5/6 finalized the complete bladder diary, 1/6 recorded only the heavy incontinence episodes (score = 3). 4/6 completed the padtest. In all patients who finalized the bladder diary the number of UUI episodes decreased, in 3/5 with ≥60%. The heavy incontinence episodes (score = 3) were resolved in 2/6 patients, and improved ≥80% in the other 4. The severity score of the UUI episodes/void was improved with ≥ 60% in 3/5 patients. The mean subjective improvement was 73%. CONCLUSION: This feasibility study indicates that subject-controlled, on-demand DGN stimulation using a percutaneously placed electrode is possible over a longer time period, in a home setting, with a positive effect on non-neurogenic overactive bladder symptoms with UUI. Although the placement is an easy procedure, it is difficult to fixate the electrode to keep it in the correct position. Improvements in hardware, like a better fixated electrode and an easy to control stimulator, are necessary to make SODGNS a treatment possibility in the future.

Sex conversion surgery in a man with severe gender dysphoria. A tragic outcome.

Although hundreds of "sex transformation" operations have been performed, little is known about the long-term postoperative adjustment. Available outcome data suggest that sex reassignment surgery in male patients is followed by a better social as well as inner adjustment in the vast majority, at least for the first several years after surgery. Surprisingly, only a handful of cases with poor outcomes have been reported. This report concerns a 53-year-old biological male with a life-long gender dysphoria who, although subjectively pleased with the surgery, developed a paranoid psychosis five years after sex conversion surgery.

Critical review of psychosocial interventions in cancer care.

The need for a large variety of psychosocial interventions is enhanced as increasing numbers of patients with cancer have longer survival. This article reviews the four interventions used most commonly: (1) education, (2) behavioral training, (3) individual psychotherapy, and (4) group interventions. It examines the outcomes of each type of intervention. This comprehensive review of the intervention literature reveals the availability of a wide range of options for patients with cancer and their potential psychological and physical health benefits.

A structured psychiatric intervention for cancer patients. I. Changes over time in methods of coping and affective disturbance.

We evaluated the immediate and long-term effects on psychological distress and coping methods of a 6-week, structured, psychiatric group intervention for postsurgical patients with malignant melanoma. The intervention consisted of health education, enhancement of problem-solving skills, stress management (eg, relaxation techniques), and psychological support. In spite of good prognosis, most patients had high levels of psychological distress at baseline, comparable with other patients with cancer. However, at the end of brief psychiatric intervention, the experimental subjects (n = 38), while not without some distress, exhibited higher vigor and greater use of active-behavioral coping than the controls (n = 28). At 6 months' follow-up, the group differences were even more pronounced. The intervention-group patients then showed significantly lower depression, fatigue, confusion, and total mood disturbance as well as higher vigor. They were also using significantly more active-behavioral and active-cognitive coping than the controls. These results indicate that a short-term psychiatric group intervention for patients with malignant melanoma effectively reduces psychological distress and enhances longer-term effective coping.

Malignant melanoma. Effects of an early structured psychiatric intervention, coping, and affective state on recurrence and survival 6 years later.

OBJECTIVES: We evaluated recurrence and survival for 68 patients with malignant melanoma who participated in a 6-week structured psychiatric group intervention 5 to 6 years earlier, shortly after their diagnosis and initial surgical treatment. We also explored the role of several factors as possible predictors of outcome. DESIGN: This was a randomized controlled experimental study. The Cox proportion hazards regression model was used to quantify the relationship between treatment and the outcomes adjusted by the covariates (age, sex, Breslow depth, tumor site, baseline Profile of Mood States Total Mood Disturbance, baseline active-behavioral coping, baseline natural killer cell activity, and treatment [ie, group intervention]). The stepwise procedure was used for covariate selection. RESULTS: For control patients, there was a trend for recurrence (13/34) and a statistically significant greater rate of death (10/34) than for experimental patients (7/34 and 3/34, respectively). We found that being male and having a greater Breslow depth predicted greater recurrence and poorer survival. Analysis of multiple covariates found that only Breslow depth and treatment (ie, group intervention) were significant. Adjusting for Breslow depth, treatment effect remained significant. Finally, baseline affective distress and baseline coping were significant psychobehavioral predictors for recurrence and survival. Surprisingly, higher levels of baseline distress as well as baseline coping and enhancement of active-behavioral coping over time were predictive of lower rates of recurrence and death. CONCLUSION: Psychiatric interventions that enhance effective coping and reduce affective distress appear to have beneficial effects on survival but are not proposed as an alternative or independent treatment for cancer or any other illness or disease. However, the exact nature of this relationship warrants further investigation.

A structured psychiatric intervention for cancer patients. II. Changes over time in immunological measures.

We evaluated the immediate and long-term effects on immune function measures of a 6-week structure psychiatric group intervention for patients with malignant melanoma. Along with a reduction in levels of psychological distress and greater use of active coping methods, the following immune changes were seen at the 6-month assessment point in the intervention-group patients (n = 35) compared with controls (n = 26): significant increases in the percent of large granular lymphocytes (defined as CD57 with Leu-7) and natural killer (NK) cells (defined as CD16 with Leu-11 and CD56 with NKH1) along with indications of increase in NK cytotoxic activity; and a small decrease in the percent of CD4 (helper/inducer) T cells. At the 6-week follow-up point, the majority of these changes were not yet observable. The results indicate that a short-term psychiatric group intervention in patients with malignant melanoma with a good prognosis was associated with longer-term changes in affective state, coping, and the NK lymphoid cell system. Affective rather than coping measures showed some significant correlations with immune cell changes.

The effect of marital status on stress in medical school.

Two competing explanations have been offered to explain why the unmarried experience greater stress--the protection/support hypothesis (emotional support from a spouse offsets daily tensions) and the selection hypothesis (the more emotionally mature individual marries). To assess these hypotheses, the authors compared the difference in stress levels between 61 married and unmarried students during the stressful years of medical school. Stress was measured each year by attrition rates, self-reports, and interviews with spouses. The stressors of medical school were more severe for the single students; moveover, stress levels of formerly single students declined after marriage. The authors believe these results affirm the protection/support hypothesis.

Effects of weight loss on the dexamethasone suppression test.

The authors studied postdexamethasone cortisol secretion in 18 depression-free, healthy, obese subjects before and after weight loss. Although all subjects suppressed cortisol normally before weight loss, 5 of 18 (27.5%) failed to suppress cortisol after an average loss of 13.5 kg. This failure to suppress cortisol was not associated with any change in depression ratings.

Changes in AIDS risk behaviors among homosexual male physicians and university students.

Two samples of homosexual men, 64 physicians and 58 university students, reported profound decreases in several sexual practices linked to transmission of acquired immune deficiency syndrome (AIDS). The physicians showed the greater reduction. When sociodemographic variables, health beliefs, feeling of control over outcome, mood, sexual interest before the AIDS epidemic, and medical care utilization were correlated with decrease and/or increase in AIDS risk behaviors, the clusters of variables most strongly correlated with change in risk behaviors differed between the physicians and students. Interventions designed to change behaviors in AIDS high-risk groups should be tailored for specific subgroups.

Psychosocial interventions for patients with cancer: what works and what doesn't.

With the successes that have been achieved in cancer care leading to patients surviving longer, the need for a variety of psychosocial intervention models is posing a new challenge to the field. This article reviews the general categories of interventions used most commonly: (1) education; (2) coping; (3) emotional support; and (4) psychotherapy. It provides a theoretical model for designing psychosocial interventions, and provides guidelines for assessing what works and what doesn't.

Adaptation of adult bone marrow transplant recipient long-term survivors.

Although there is a small literature on psychosocial and psychiatric aspects of bone marrow transplants (BMT) in adult recipients during the BMT hospitalization phase, adaptation of long-term adult BMT recipient survivors has received little study. This study surveyed the adaptation of BMT recipient survivors over age 17 who were an average of 42 months posttransplant. Study variables included the recipients' current self-reported health status, mood state, social role function, self esteem, life satisfaction, and relationships with their BMT donors and other family members. A companion study of those who donated BMT to the recipients eligible for this study was also performed. The study participants were preponderantly young adults who currently were in an intimate relationship and vocationally active. About 1/4 of the subjects reported ongoing medical problems. Also, 15-25% reported significant emotional distress, low self-esteem, and less-than-optimal life satisfaction. The subjects' current quality of relationship with their donors was highly correlated with many measures of their psychosocial status. The findings indicate that about 75% of BMT recipient long-term survivors are doing well from a psychosocial as well as a medical standpoint, that the recipient-donor relationship may be sensitive to any changes in the recipient's status, and that 15-20% of BMT recipient survivors report a degree of psychological distress that might benefit from specific psychological/psychiatric intervention.

Psychological adjustment of adult bone marrow transplant donors whose recipient survives.

The psychosocial and psychiatric impact of donating bone marrow (BM) has received little study. This mail questionnaire study of bone marrow donors whose recipient had survived more than one year post-BMT was undertaken to document the psychosocial consequences of donation on "successful" BM donors. Demographic, mood state, self-esteem, current life satisfaction, and donor-recipient relationship characteristics, donor-perceived approval from family members, and donor attitudes about BM donation were studied. A companion study of BM recipients was also performed to provide comparative data on the psychosocial status of donors and recipients. As a group BM donors manifested little emotional distress, high self-esteem, and a high degree of current life satisfaction. Donors reported little change in their relationships with their recipients since the BMT. However the current quality of their relationships with their recipients was highly correlated with several recipient health status and psychosocial variables, suggesting that recipient deterioration might significantly adversely impact donor psychosocial status. From 10% to 20% of donors indicated at least some negative consequences of donating.

Data omitted from psychiatric consultation notes.

To assess how often psychiatric consultants omit written data from their consultation notes, the authors reviewed 78 initial consultation notes written by second-year psychiatric residents. Data considered essential for an adequate psychiatric evaluation were typically omitted. Categories that were observed to have the highest frequencies of missing data included family history of psychiatric illness (60.3%), history of substance abuse (44.9%), marital status (37.2%), previous psychotropic drug use (35.9%), previous psychiatric treatment (26.9%), and patient history of psychiatric illness (24.4%). The frequencies of omissions were significantly (p less than .001, except for the last item, p less than .01) higher than those from the consultation notes written by a second cohort of psychiatric residents who used a worksheet that listed data categories. The authors' findings argue for the use of worksheets delineating data categories to ensure that clinicians write adequate consultation notes.

Role of the physician in bereavement.

The purpose of this article is to set forth a clear and concise guide for physicians to use in their treatment of the bereaved. The physician's attitudes toward death and dying, as well as normal and abnormal grief reactions, are reviewed. The role of the physician prior to the time of death, at the time of death, and after the death are discussed. Models of hospital-based programs that can be of significant help to physicians in treating the bereaved are presented also.

Preventing nursing burnout: a challenge for liaison psychiatry.

The authors conducted a study to assess and compare the level of job satisfaction among five groups of registered nurses working at UCLA Hospital. Fifty-seven female nurses completed the MMPI, Locus of Control Test, Work Environment Scale, and a questionnaire designed to assess job satisfaction. Results showed that there were no significant personality differences among the five groups of nurses. Significant differences between some of the groups were found in demographic variables and in work-related variables such as involvement, task orientation, work pressure, sense of authority on the job, and perceived communication with peers or other groups in the work environment. Nurses on the Medicine unit tended to have lower overall job satisfaction than those in the other units. The involvement of the Psychiatric Liaison Service on the five nursing units is described and discussed as a possible method for providing psychosocial support to the nurses and reducing high turnover rates.
