Influence of pain and urinary symptoms on quality of life in young men with chronic prostatitis-like symptoms

BACKGROUND: Our aims in the present study were to estimate the influences of pain and urinary symptoms on quality of life, and to determine which of these two variables has the most predictive power with respect to quality of life in young men with chronic prostatitis-like symptoms. METHODS: Chronic prostatitis-like symptoms were measured by the National Institutes of Health-Chronic Prostatitis Symptom Index. Of the 28,841 men aged 20 years who lived in the study community, 18,495 men (a response rate 64.1%) agreed to participate in the study. A total of 1057 men who complained of symptoms indicative of chronic prostatitis were included in the study. The influences of pain and urinary symptoms on quality of life were determined using logistic regression analysis. The receiver operating characteristic (ROC) curve was used to estimate the predictive ability of each of these variables with respect to quality of life. RESULTS: Results from multivariate analysis showed that both pain and urinary symptoms were associated with an increased likelihood of impaired quality of life, although pain contributed more to a reduced quality of life than urinary symptoms. Relative to men who experienced mild pain, men who experienced moderate pain had a 3.9-fold risk of poor quality of life (odds ratio [OR], 3.87; 95% confidence interval [CI], 2.86-5.23; P < 0.001) and those who experienced severe pain had a 15.7-fold risk of reduced quality of life (OR, 15.68; 95% CI, 6.59-37.35; P < 0.001). Moderate urinary symptoms were associated with a 1.4-fold risk of bother (OR, 1.41; 95% CI, 1.01-1.99; P < 0.001) and severe urinary symptoms were associated with 2.4-fold risk (OR, 2.39; 95% CI, 1.37-4.12; P < 0.001), relative to mild urinary symptoms. Comparison of the effects of pain and urinary symptoms showed that pain severity had the most predictive power for bother, quality of life, and quality-of-life impact. The areas under the ROC curves for bother, quality of life, and quality-of-life impact were 71.3%, 69.3% and 72.5%, respectively. CONCLUSION: Urinary symptoms and pain might be associated with an increased likelihood of impaired quality of life in young men with chronic prostatitis-like symptoms. In addition, our findings suggest that pain severity is the most influential variable for determining quality of life in this population.     

Clinical evaluation of preventive and class-I composite resin restorations.

This study was initiated in 1986 in response to increased interest in restorative procedures favoring preservation of tooth substance and in the search for alternatives to dental amalgams. Eighty-seven preventive resin restorations in permanent molars and 35 occlusal composite resin restorations in primary molars (limited size) and 13 in premolars were followed up for 2 years. They were placed by a large number of operators, mainly dental students under supervision, and rated by five calibrated instructors in accordance with an internationally accepted system for the evaluation of the clinical performance of dental materials. One composite resin (Occlusin) was used. A survival model was used to calculate the cumulative theoretical number of successful treatments of children who had dropped out. For none of the 6 clinical variables was the success rate lower than 91%, and only 3 of 26 failures were of a nature requiring remake or correction. The failures occurred, with a few exceptions, during the 1st year of observation. The two types of restoration have thus proved to be efficient treatments fulfilling all reasonable requirements in modern operative dentistry.     

A comparison of the effects of omeprazole and ranitidine on gastric secretion in women undergoing elective Caesarean section

This study compares the efficacy of omeprazole and ranitidine at reducing gastric secretion in obstetric patients. Sixty-five women scheduled to undergo elective Caesarean section under general anaesthesia were randomly allocated to receive either omeprazole 40 mg or ranitidine 150 mg orally at 2200 hours the night before and at 0600 hours on the morning of surgery. Intragastric pH and volume were measured immediately after induction of anaesthesia and on completion of surgery. All patients had gastric aspirates less than 25 ml. None of the omeprazole group had an aspirate of pH less than 3.5. Six patients (19%) in the ranitidine group had aspirates of pH less than 3.5, a significant difference from the omeprazole group (p less than 0.05). Of these six, two (6%) had aspirates of pH less than 2.5. Hence this study showed that omeprazole was more effective and consistent than ranitidine at maintaining gastric pH greater than 3.5.     

Autonomic Nervous System Function and Essential Hypertension: Individual Response Specificity With and Without Beta-Adrenergic Blockade

The aim of the present research was to study individual response specificity in 22 male patients having essential hypertension (HT) and to compare these patients with age-matched male normotensive controls (NT). Four stimuli, letter identification, mental arithmetic, cold pressor and isometric exercise, were administered while recordings were made of: systolic and diastolic blood pressures, heart rate, respiration, forearm and hand blood flows, and skin conductance level and fluctuations. After each session urine samples were collected and epinephrine and norepinephrine levels were analyzed. Twelve subjects in the HT group were given beta-adrenergic blocking agents and retested 1 to 21 months (X?= 12 months) after the first session. Each response was standardized, using NT as the reference group. Intraclass correlations were computed to evaluate whether HT males reacted with a more consistent hierarchy of responses than did NT. Intraclass correlations were significantly higher among the patients than in the control group, regardless of whether the blood pressure response was included or excluded in the computation of the intraclass correlations. Thus, we conclude that male HT patients show more individual response specificity than NT controls. Beta-adrenergic receptor antagonists reduced levels of cardiovascular activity and attenuated reactivity but did not affect amount of specificity. Thus, intraclass correlations provide unique and useful information, since they are not related to blood pressure reactivity or to urinary catecholamine levels, nor affected by beta-adrenergic blockade.     

A homeo domain protein reveals the metameric nature of the developing chick hindbrain

The segmented embryonic hindbrain of vertebrates develops by sequential constriction of the neural tube into eight metameric units known as rhombomeres. The cellular and molecular basis of this segmentation process is largely unknown. Using an antibody, we analyzed the expression pattern of the chick homeo domain-containing protein Ghox-lab in the developing chick hindbrain. At the neural plate stage, prior to the appearance of rhombomeres, Ghox-lab is expressed within a single domain that extends anteriorly up to the site where rhombomere 4 will later form. After rhombomere 4 has appeared and as hindbrain segmentation progresses, the level of Ghox-lab protein increases significantly within the fourth rhombomere. This intensification, accompanied by the elimination of Ghox-lab protein in rhombomeres 5 and 6, eventually results in the formation of a distinct island of expression in rhombomere 4. All cells in the newly formed rhombomere 4 express Ghox-lab, except for the cells of the floor plate. In addition, neural crest cells migrating from the fourth rhombomere are also Ghox-lab-positive. These data raise the possibility that Ghox-lab protein might be one of the factors involved in the specification of the metameric pattern of the vertebrate hindbrain.

Behavioral effects of a comprehensive, multifactorial program for lifestyle change after percutaneous transluminal coronary angioplasty: a prospective, randomized controlled study

A group of 93 coronary patients recently treated with percutaneous transluminal coronary angioplasty (PTCA) were randomly assigned to either an intervention or a control group. Subjects in the intervention group participated in a comprehensive behaviorally oriented program aimed at achieving significant long-term changes in risk factor-related lifestyle behavior. Assessments of lifestyle behaviors, psychological factors, biological risk factors, and rehabilitation as well as secondary prevention endpoints were carried out, at inclusion and after 12 months. Results showed that the intervention patients, as compared with controls, improved significantly on measures assessing smoking, exercise, and diet habits. These self-rated changes were confirmed by weight reductions and improved exercise capacity, as well as by between-group differences in subclinical chest pain during an exercise test. However, few effects were found on the different psychological variables, as well as on morbidity or return to work.     

Risk factors for the progression or persistence of untreated mild dysplasia of the uterine cervix

To identify the factors that may predict the progression or persistence of untreated mild dysplasia of the uterine cervix, we performed a retrospective review of 118 patients with histologically verified mild dysplasia who underwent colposcopic biopsies between January 1999 and December 2003. Regression to normal occurred in 70.3%, progression to moderate dysplasia or worse occurred in 11.0%, and persistence of mild dysplasia occurred in 18.7%. In regression/progression analysis, progression of untreated mild dysplasia was 34.5% (10/29) in patients with high viral loads (> or =100 relative light units/positive control [RLU/PC]) and 4.5% (3/67) in those with low viral loads (1 to <100 RLU/PC) and negative human papillomavirus (HPV) tests (P < 0.001). Women with high viral loads had a 13-fold greater chance of progression of untreated mild dysplasia than those with low viral loads and negative HPV tests (CI: 2.494-95.297; P = 0.0022). Those associated with both positive smear and positive HPV test (12/45 = 26.7%) were at a greater risk of progression of untreated mild dysplasia as compared with those with positive smear and negative HPV (0/17 = 0.0%) or those with negative smear and positive HPV test (1/18 = 5.6%). Those with high viral loads and both with positive smear and positive HPV test should be followed closely because of their increased risk of progression of untreated mild dysplasia.
