Urinary morbidity following ultrasound-guided transperineal prostate seed implantation.

PURPOSE: To assess the urinary morbidity experienced by patients undergoing ultrasound-guided, permanent transperineal seed implantation for adenocarcinoma of the prostate. METHODS AND MATERIALS: Between September 1992 and September 1997, 693 consecutive patients presented with a diagnosis of clinically localized adenocarcinoma of the prostate, and were treated with ultrasound-guided transperineal interstitial permanent brachytherapy (TPIPB). Ninety-three patients are excluded from this review, having received neoadjuvant antiandrogen therapy. TPIPB was performed with 125I in 165 patients and with 103Pd in 435 patients. Patients treated with implant alone received 160 Gy with 125I (pre TG43) or 120 Gy with 103Pd. One hundred two patients received preimplant, pelvic external beam radiation (XRT) to a dose of either 41.4 or 45 Gy because of high-risk features including PSA > or = 10 and/or Gleason score > or = 7. Combined modality patients received 120 Gy and 90 Gy, respectively for 125I or 103Pd. All patients underwent postimplant cystoscopy and placement of an indwelling Foley catheter for 24-48 h. Follow-up was at 5 weeks after implant, every 3 months for the first 2 years, and then every 6 months for subsequent years. Patients completed AUA urinary symptom scoring questionnaires at initial consultation and at each follow-up visit. Urinary toxicity was classified by the RTOG toxicity scale with the following adaptations; grade 1 urinary toxicity was symptomatic nocturia or frequency requiring none or minimal medical intervention such as phenazopyridine; grade 2 urinary toxicity was early obstructive symptomatology requiring alpha-blocker therapy; and grade 3 toxicity was considered that requiring indwelling catheters or posttreatment transurethral resection of the prostate for symptom relief. Log-rank analysis and Chi-square testing was performed to assess AUA score, prostate size, isotope selection, and the addition of XRT as possible prognosticators of postimplant urinary toxicity. The prostate volume receiving 150% of the prescribed dose (V150) was studied in patients to assess its correlation with urinary toxicity. RESULTS: Median follow-up was 37 months (range 6-68). Within the first 60 days, 37.3% of the patients reported grade 1 urinary toxicity, 41% had grade 2, and 2.2% had grade 3 urinary toxicity. By 6 months, 21.4% still reported grade 1 urinary toxicity, whereas 12.8% and 3% complained of grade 2 and 3 urinary difficulties, respectively. Patients with a preimplant AUA score < or = 7 had significantly less grade II toxicity at 60 days compared to those with an AUA score of >7 (32% vs. 59.2%, respectively, p = 0.001). Similarly, prostatic volumes < or = 35 cc had a significantly lower incidence of grade II urinary toxicity (p = 0.001). There was no difference in toxicity regarding the isotope used (p = 0.138 at 60 days, p = 0.45 at 6 months) or the addition of preimplant XRT (p = 0.069 at 60 days, p = 0.84 at 6 months). Twenty-eight patients (4.7%) underwent TURP after 3 isotope half-lives for protracted obstructive symptoms. Five of these men (17%) developed stress incontinence following TURP, but all patients experienced relief of their obstructive symptoms without morbidity at last follow-up. The percent of the prostate receiving 150% of the prescribed dose (V150) did not predict urinary toxicity. CONCLUSIONS: TPIPB is well tolerated but associated with mild to moderate urinary morbidity. Pretreatment prostatic volume and AUA scoring were shown to significantly predict for grade 2 toxicity while the use of preimplant, pelvic XRT and isotope selection did not. Patients undergoing TURP for protracted symptoms following TPIPB did well with a 17% risk of developing stress incontinence. V150 did not help identify patients at risk for urinary morbidity. As transperineal prostate implantation is used more frequently the associated toxicities and the definition of possible pretreatment prognostic factors is necessary to

Temporal resolution of urinary morbidity following prostate brachytherapy.

PURPOSE: To report the short-term urinary morbidity for prostate brachytherapy patients without a preimplant history of a transurethral resection of the prostate gland and who received prophylactic and prolonged alpha-blockers. alpha-blockers may decrease radiation-induced urethritis and increase urinary flow. Multiple clinical and treatment parameters were evaluated to identify factors associated with increased acute urinary morbidity. MATERIALS AND METHODS: One hundred seventy consecutive patients without a prior history of a transurethral resection of the prostate gland underwent transperineal ultrasound guided prostate brachytherapy for clinical T1c-T3a carcinoma of the prostate gland. For all patients, an alpha-blocker was initiated prior to implantation and continued at least until the international prostate symptom score (IPSS) returned to baseline levels. Clinical parameters evaluated for short-term urinary morbidity included patient age, clinical T stage, preimplant IPSS (obtained within 3 weeks of implantation), and prostate ultrasound volume. Treatment parameters included the utilization of neoadjuvant hormonal manipulation, the utilization of moderate dose external beam radiation therapy before implantation, the choice of isotope, the urethral dose, the total implant activity in millicuries, and a variety of dosimetric quality indicators (D(90) and V(100)/V(150)/V(200)). Catheter dependency and the duration of alpha-blocker dependency was also evaluated. On average, 11.2 IPSS surveys were obtained for each patient. RESULTS: One hundred fifty of the 170 patients (88.2%) had the urinary catheter permanently removed on day 0. Only one patient required an urinary catheter for > 5 days. Two patients (1.2%) required a subsequent transurethral resection of the prostate gland because of prolonged obstructive/irritative symptoms. To date, no patient has developed an urinary stricture or urinary incontinence. The IPS score on average peaked at 2 weeks following implantation. This score returned to within 1 point of the antecedent value at a median of 6 weeks and a mean of 13.3 weeks. At 26 and 50 weeks, 85% and 56% of the patients, respectively, continued with alpha-blockers. Of the clinical and treatment parameters evaluated for short-term urinary morbidity, only variants of the IPSS such as the maximum, maximum increase, and preimplant IPSS values correlated with time to return to the referent zone with p < 0.05. CONCLUSION: The return of the IPS score to baseline occurred more rapidly in our series than what has previously been reported. The 1.2% incidence of transurethral resections also compares favorably with the published literature. We believe these results may be due to maintaining the average urethral dose to approximately 115% of the prescribed dose and the prophylactic and long-term use of alpha-blockers.

Effects of valsartan on morbidity and mortality in patients with heart failure not receiving angiotensin-converting enzyme inhibitors.

OBJECTIVES: A subgroup analysis of the Valsartan Heart Failure Trial (Val-HeFT) was performed to evaluate the effects of the angiotensin II receptor blocker, valsartan, in the patients with chronic heart failure (HF) not receiving angiotensin-converting enzyme (ACE) inhibitors. BACKGROUND: The ACE inhibitors reduce mortality and morbidity in patients with HF. Nonetheless, nearly 20% of potentially eligible patients may not be prescribed ACE inhibitors. RESULTS: Val-HeFT was an international, randomized, double-blinded trial that compared valsartan with placebo when added to the prescribed treatment of patients with HF. The two primary end points of the study were all-cause mortality and the composite of all-cause mortality and morbidity (sudden death with resuscitation, hospital admission for HF, or administration of intravenous inotropic or vasodilator drugs for >or=4 h without hospital admission). Of the 5,010 patients enrolled in the trial, 366 (7.3%) were not treated with ACE inhibitors at baseline. The effects of valsartan on the primary and secondary end points of the study were assessed in this subgroup of patients. RESULTS: Both all-cause mortality and combined mortality and morbidity for patients not treated with ACE inhibitors were significantly reduced in the valsartan treatment group compared with the placebo group (17.3% vs. 27.1%, p = 0.017 and 24.9% vs. 42.5%, p < 0.001, respectively). Consistent with the data on clinical events, patients randomized to valsartan showed improvements in physiologic variables, such as ejection fraction, left ventricular internal diameter in diastole, and plasma neurohormone levels. Permanent discontinuation of study treatment because of adverse experiences was comparable between the two groups. CONCLUSIONS: Val-HeFT has provided the first placebo-controlled outcome data demonstrating a favorable effect of an angiotensin receptor blocker on mortality and morbidity in patients with HF not treated with ACE inhibitors. Based on these results, valsartan appears to be an effective therapy in ACE inhibitor-intolerant patients.

Cardiovascular morbidity and mortality among hypertensive patients in general practice: the evaluation of long-term systematic management.

OBJECTIVE: To evaluate systematic management of hypertensive patients with regard to cardiovascular morbidity and mortality. DESIGN: In a matched cohort study (1978-1993) the number of cardiovascular events among hypertensive patients under continuous systematic management in four general practices was compared with those occurring among hypertensive patients from eight "usual care" general practices. SUBJECTS: The source population consisted of employees of a major electronic company in Eindhoven with hypertension as determined at an occupational health examination. The index group (n = 120) consisted of employees who were participating in the systematic management program in four practices. A reference group of 120 patients was selected from hypertensive employees who were registered in eight "usual care" practices by matching for age, gender, fasting blood glucose, and frequency of occupational health examinations. The total cohort consisted primarily of males (78%), whose ages ranged from 50 to 65 years. MAIN OUTCOME MEASURES: Risk difference (RD) per 1000 patient years regarding left ventricular hypertrophy, heart failure, angina pectoris, myocardial infarction, transient ischaemic attack, stroke, peripheral arterial disease, nephropathy, retinopathy, cardiac death, death due to stroke, and non-cardiovascular death was determined. In addition to morbidity and mortality, systematic hypertension management was evaluated with regard to cardiovascular risk factors throughout a period of maximally 12 successive years (1978-1989). Morbidity and mortality data were derived from general practice records and archives; data on risk factors were assessed at bi-annual occupational health examinations. RESULTS: The total follow-up duration amounted to 2628 patient years. The mean follow-up duration in the index group was 10.8, in the reference group 11.1 years. As compared to the "usual care" reference group, the index group showed less left ventricular hypertrophy (RD 8.2, 95% CI 1.4-15.0), less angina pectoris (RD 9.7, 95% CI 2.0-17.4) and less peripheral arterial disease (RD 3.7, 95% CI 0.5-7.1). The difference in mean decrease in blood pressure during follow-up was 11.3 mmHg systolic and 5.9 mmHg diastolic in favour of the index group. No significant differences between the index and the reference groups were found with regard to the changes in other risk factors. CONCLUSION: In our study systematic management of hypertensive patients aged 50 to 65 in general practice was associated with a statistically significant, and clinically relevant decrease in cardiovascular morbidity and blood pressure. Although causality cannot be determined from this non-randomized cohort study, the findings do support the view that systematic management of hypertensive patients in general practice is valuable.

Increased morbid risk for schizophrenia in families of in-patients with bipolar illness.

BACKGROUND: It has been reported that relatives of probands with severe, psychotic forms of bipolar illness have increased rates of schizophrenia but not the relatives of individuals with milder, non-psychotic forms of disorder. In this study, we examined the prevalence of psychiatric disorders in the first degree relatives of a sample of 103 inpatients with bipolar disorder and in a matched control sample of 84 healthy individuals. METHOD: Relatives of cases and controls were interviewed using the FH-RDC to determine familial morbid risk for schizophrenia and bipolar disorder. Age- and sex-adjusted morbidity risks were calculated in both samples according to the method of Strömgren. RESULTS: The morbid risks for both bipolar disorder (4.9%) and schizophrenia (2.8%) were higher in relatives of patients than in relatives of controls (0.3% and 0.6% respectively). The relative risks were 14.2 [95% confidence interval (CI)=3.1-64.2] for bipolar disorder and 4.9 (95% CI=1.3-18.8) for schizophrenia. Relatives of women with early onset of bipolar illness had the highest morbid risks for both bipolar illness and schizophrenia. The presence of more than one patient with bipolar disorder in a family increased the risk for schizophrenia nearly fourfold (RR=3.5, 95% CI=1.2-10.2). There was no additional effect of presence of psychotic features. CONCLUSION: Our results suggest that the transmission of psychosis is not disorder-specific. Bipolar illness characterised by a high familial loading is associated with increased risk of schizophrenia in the relatives.

The effect off-pump coronary artery bypass surgery on in-hospital mortality and morbidity.

OBJECTIVE: Off-pump coronary artery bypass (OPCAB) surgery is being increasingly reported to show better outcomes compared to conventional on bypass grafting. We examined the effect of OPCAB on in-hospital mortality and morbidity, while adjusting for patient and disease characteristics, in four institutions in the North West of England. METHODS: Between April 1997 and March 2001, 10,941 consecutive patients underwent isolated coronary artery bypass surgery at these four institutions. Of these, 7.7% were performed off-pump. We used logistic regression to examine the effect of OPCAB on in-hospital mortality and morbidity after adjusting for potentially confounding variables. RESULTS: The crude odds ratio (OR) for death (off-pump versus on-pump coronary bypass grafting) was 0.48 (95% confidence interval, CI 0.26-0.92; P=0.023). After adjustment for all major risk factors, the OR for death was 0.59 (95% CI 0.31-1.12; P=0.105). Off-pump patients had a substantially reduced risk of post-operative stroke (0.6 versus 2.3%, respectively; adjusted OR 0.26 (95% CI 0.09-0.70; P=0.008) and a significant reduction in post-operative hospital stay. Other morbidity outcomes were similar in both groups. CONCLUSIONS: Off-pump coronary artery bypass incurs no increased risk of in-hospital mortality. In contrast, there is a significant reduction in morbidity in patients undergoing off-pump coronary bypass grafting when compared to that performed on cardiopulmonary bypass.

Household mouse allergen exposure and asthma morbidity in inner-city preschool children.

BACKGROUND: Inner-city children experience disproportionate asthma morbidity, and suspected reasons include indoor environmental exposures. OBJECTIVE: To determine if mouse allergen exposure is a risk factor for asthma morbidity. METHODS: Preschool children with asthma were recruited from inner-city Baltimore, MD. Skin testing was performed and blood was collected at the baseline visit for quantification of mouse allergen specific IgE. A questionnaire evaluated symptoms, medication, and health care use at baseline, 3 months, and 6 months. A trained technician collected dust samples from the child's home for analysis of Mus m 1 at baseline, 3 months, and 6 months. Outcomes were compared between mouse-sensitized, highly exposed children and all other children. RESULTS: A total of 127 children had complete data for mouse sensitization status and bedroom settled dust mouse allergen levels at baseline. The mean age of the children was 4.4 years, 92% were African American, and 26% were sensitized to mouse. Mouse-sensitized children exposed to higher levels of Mus m 1 (>0.5 microg/g) had 50% more days of symptoms (incidence rate ratio [IRR], 1.5; 95% confidence interval [CI], 1.1-2.1) and 80% more days of beta-agonist use than other children (IRR, 1.8; 95% CI, 1.3-2.5). Children in the sensitized and highly exposed group were also more likely to have an unscheduled physician visit (odds ratio [OR], 3.1; 95% CI, 1.6-6.3), emergency department visit (OR, 2.1; 95% CI, 1.1-4.1), and hospitalization (OR, 36.6; 95% CI, 4.1-327.3) than other children. These associations between mouse allergen exposure and asthma symptoms and morbidity remained statistically significant after adjusting for potential confounders, including atopy and cockroach sensitization and exposure. CONCLUSIONS: In mouse-sensitized inner-city children, exposure to mouse allergen may be an important cause of asthma morbidity.

Effect of postoperative epidural analgesia on morbidity and mortality after total hip replacement surgery in medicare patients.

BACKGROUND AND OBJECTIVES: The effect of postoperative epidural analgesia (vs. systemic analgesia) on patient outcomes is unclear. Available randomized controlled trials (RCTs) have focused on the intraoperative period and not properly examined the effect of postoperative epidural analgesia (EA) on outcomes. METHODS: A 5% nationally random sample of Medicare beneficiaries from 1994 to 1999 was analyzed to identify patients undergoing total hip arthroplasty (Common Procedural Terminology [CPT] code 27130, 27132, 27134, 27137, 27138). Patients were divided into 2 groups depending on the presence or absence of postoperative EA based on the CPT coding (01996). The rate of major morbidity (acute myocardial infarction, deep venous thrombosis, pulmonary embolism, angina, respiratory failure, heart failure, cardiac dysrhythmias, pneumonia, pulmonary edema, sepsis, acute renal failure, paralytic ileus, acute cerebrovascular event) and death at 7 and 30 days after the procedure were compared. Multivariate regression analysis was performed to determine if the presence of postoperative (EA) had an independent effect on mortality or major morbidity. Data were reported as an odds ratio with 95% confidence intervals (CI) when appropriate. RESULTS: The unadjusted 7- and 30-day death rate was significantly lower for EA versus no EA (1.9/1000 [95% CI: 0.2-3.6] vs. 3.9/1000 [95% CI: 3.0-6.2] at 7 days [P =.04] and 5.8/1000 [95% CI: 2.9-8.7] vs. 9.9/1000 [95% CI: 8.6-11.3] at 30 days [P = 0.01]). However, multivariate regression analysis revealed that there was no difference between the groups with regard to mortality or major morbidity with the exception of an increase in deep venous thrombosis in patients who received EA. CONCLUSIONS: The use of postoperative EA was not associated a lower incidence of mortality and major morbidity in Medicare patients undergoing total hip arthroplasty. However, the results should be interpreted with caution because of limitations in using the Medicare claims data for analysis. Further trials using other properly conducted and designed studies (e.g., RCTs) would be ideal to validate these results.

Subsequent pregnancy affects morbidity of previous child.

A prospective study of 113 children in rural Bhutan registered their morbidity and weight and their mothers' subsequent pregnancies, monthly for 32 months during the children's first 3 years of life. Children whose mothers had a subsequent birth interval of 18-30 months had an incidence of diarrhoea during the subsequent pregnancy 50% higher than their matched cohort whose mothers did not become pregnant (p = 0.02). The relative risk for diarrhoea calculated from pooled child months was 1.51. Children whose mothers became pregnant also tended to have a higher incidence of skin infections. Children, whose mothers were pregnant when they terminated breastfeeding, experienced an increased incidence of diarrhoea around weaning (p = 0.01). Children weaned at the same age from non-pregnant mothers did not show increased morbidity. This study, for the first time, relates observations of children's morbidity directly in time to the occurrence of the mother's subsequent pregnancy, and provides evidence of a causal relationship between a moderately short subsequent birth interval and a concurrent increase in morbidity for the study child.

Contrasting demographic patterns of minor psychiatric morbidity in general practice and the community.

The 60-item General Health Questionnaire was completed by 90% of 4798 patients aged 15--69 years who consulted, on one day, the general practitioners of 97% of practices in the Perth Statistical Division. A point prevalence rate of minor psychiatric morbidity in various demographic groups was calculated in terms of the population at risk. The demographic pattern of morbidity was compared with that found in a probability sample of 2324 community residents drawn from the same population at risk, and surveyed at the same time using the same time using the same screening instrument. Widowed persons, British-born men who had recently migrated to Australia, and lower-social-class men with minor psychiatric morbidity were under-represented in general practice. Elderly men and women in upper-class occupations with minor psychiatric morbidity were over-represented in general practice. These differences, unlike others that were found, could not be explained by differing consulting habits or by differing completion rates of the screening instrument.

Prevalence of psychiatric morbidity in the adult population of a rural South African village.

We report on the first South African two-stage community prevalence study of psychiatric morbidity, conducted in Mamre, a rural "coloured' village, 50 km from Cape Town. Randomly selected adults (N = 481) were assessed using the Self-Reporting Questionnaire (SRQ) as a first-stage screen and the Present State Examination (PSE-9) was administered to a proportion of the sample (N = 121) as the second-stage criterion. Demographic, health care utilization, and substance abuse data were also collected. Using the PSE-9 CATEGO Index of Definition of 5, the weighted prevalence of psychiatric morbidity was 27.1% (confidence interval of 19.5-34.7%), the majority of cases being given a tentative diagnosis of depressive or anxiety disorder. The CATEGO algorithm may not be fully appropriate in this cultural context as there was an apparent over-diagnosis of paranoid states. The SRQ's weighted sensitivity and specificity were 0.49 and 0.82 respectively. Overall, the SRQ correctly identified 67% of cases and non-cases. No demographic variables predicted psychiatric morbidity, but there was an indirect link between morbidity and primary care utilization. Further South African studies of the validity of both the SRQ and of criterion instruments are needed. These may contribute to knowledge regarding cultural factors affecting psychiatric diagnosis.

Pre-morbid asociality in neuroleptic-resistant and neuroleptic-responsive schizophrenia.

The purpose of this study was to evaluate whether childhood and adolescent pre-morbid asociality differed in neuroleptic-responsive and neuroleptic-resistant schizophrenia. Pre-morbid asociality was assessed with the Pre-morbid Asociality Adjustment Scale in 411 patients meeting DSM-III-R criteria for chronic schizophrenia or schizoaffective disorder categorized as being either neuroleptic-responsive or neuroleptic-resistant. Patterns of childhood and adolescent asociality were found to be different in neuroleptic-resistant and neuroleptic-responsive patients. Pre-morbid asociality during the pre-adult years was not consistently worse in patients with poor response to neuroleptic treatment. Greater impairment in late adolescent psychosexual functioning was predictive of poor outcome with regard to neuroleptic treatment.

Depressive disorders in primary care: recurrent, chronic, and co-morbid.

BACKGROUND: Preceding longitudinal course and current somatic and psychiatric co-morbidity of depression have been little investigated in primary care. METHOD: Consecutive patients (n = 1111) in primary care in the city of Vantaa, Finland, were screened for depression with the PRIME-MD, and positive cases interviewed by telephone. Cases with current depressive symptoms were diagnosed face-to-face with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I/P). A cohort of 137 patients with unipolar depressive disorders, comprising all patients with at least two depressive symptoms and clinically significant distress or disability, was recruited. The Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II), medical records, rating scales, and a retrospective life-chart were used to obtain comprehensive cross-sectional and longitudinal information. RESULTS: Current major depressive disorder (MDD) was the most prevalent depressive disorder (66%); it was usually mild to moderate but recurrent. A quarter of cases (23%) had MDD in partial remission or prodromal phase, and only 10% had true minor depression. Axis I co-morbidity was present in 59%, Axis II in 52%, and chronic Axis III disorders in 47%; only 12% had no co-morbidity. One third of patients presented with a psychological complaint, predicted by higher depression severity and younger age. CONCLUSION: From a lifetime perspective, the majority of primary-care patients with depressive disorders suffer from recurrent MDD, although they are currently often in prodromal or residual phase. Psychiatric and somatic co-morbidity are highly prevalent. Treatment of depression in primary care should not rely on an assumption of short-lived, uncomplicated mild disorders.

Official psychiatric morbidity and the incidence of schizophrenia 1881-1994.

BACKGROUND: We assess claims that the documented rise in psychiatric morbidity during the nineteenth and twentieth centuries was associated with an increasing incidence of schizophrenia. METHOD: Cross-sectional epidemiological comparison of the incidence of schizophrenia in one urban, industrialized community at three points over more than 100 years using new data from 1881-1902 and two pre-existing datasets, 1978-1980 and 1992-1994. For 1881-1902, 34 cases of schizophrenia were obtained through retrospective diagnosis, using Research Diagnostic Criteria, of a random 14.5% sample of first admissions to Nottingham Asylum (n = 330). Inter-rater reliability and leakage analyses were performed. The administrative incidence for all three studies was directly standardized against 1991 census data. Local statistics on total psychiatric morbidity in Nottingham were taken from the asylum superintendent's register and recent data from the Office of National Statistics. RESULTS: Official local and national rates of total psychiatric morbidity increased exponentially. There was no significant change in the incidence of schizophrenia over the 114-year period 1881-1994. CONCLUSIONS: The rise in both local and national official statistics of psychiatric morbidity 1881-1994 was not associated with a significant increase in the incidence of schizophrenia. Stability in the epidemiology of schizophrenia at a geographical level is found despite important demographic changes.

Morphometry in schizophrenia revisited: height and its relationship to pre-morbid function.

BACKGROUND: Morphometry, the measurement of forms, is an ancient practice. In particular, schizophrenic somatology was popular early in this century, but has been essentially absent from the literature for over 30 years. More recently, evidence has grown to support the notion that aberrant neurodevelopment may play a role in the pathophysiology of schizophrenia. Is the body, like the brain, affected by abnormal development in these patients? METHODS: To evaluate global deficit in development and its relationship to pre-morbid function, height was compared in a large group (N = 226) of male schizophrenics and a group of healthy male controls (N = 142) equivalent in parental socio-economic status. Patients in the lower quartile of height were compared to those in the upper quartile of height. RESULTS: The patient group had a mean height of 177.1 cm, which was significantly shorter than the mean height of the control group of 179.4 (P < 0.003). Those in the lower quartile had significantly poorer pre-morbid function as measured by: (1) psychosocial adjustment using the pre-morbid adjustment scales for childhood and adolescence/young adulthood, and (2) cognitive function using measures of school performance such as grades and need for special education. In addition, these measures of pre-morbid function correlated significantly with height when analysed using the entire sample. CONCLUSIONS: These findings provide further support to the idea that abnormal development may play a key role in the pathophysiology of schizophrenia. Furthermore, this is manifested as a global deficit in growth and function resulting in smaller stature, poorer social skills, and deficits in cognitive abilities.

Urban-rural mental health differences in great Britain: findings from the national morbidity survey.

BACKGROUND: Studies of urban-rural differences in prevalence of non-psychotic mental disorder have not given consistent findings. Such differences have received relatively little study in Great Britain. METHODS: Data from 9777 subjects in the Household Survey of the National Morbidity Survey of Great Britain were analysed for differences between urban, semi-rural and rural areas. Psychiatric morbidity was assessed by scores on the Revised Clinical Interview Schedule (CIS-R), together with alcohol dependence, drug dependence, receipt of treatment from general practitioners. Associations with other characteristics were examined by logistic regression. RESULTS: Urban subjects had higher rates than rural of CIS-R morbidity, alcohol dependence and drug dependence, with semi-rural subjects intermediate. Urban subjects also tended to be members of more deprived social groups, with more adverse living circumstances and greater life stress, factors themselves associated with disorder. Urban-rural differences in alcohol and drug dependence were no longer significant after adjustment for these factors by logistic regression, and differences on CIS-R morbidity were considerably reduced. There were no differences in treatment. CONCLUSIONS: There are considerable British urban rural differences in mental health, which may largely be attributable to more adverse urban social environments.

Lifetime co-morbidities between social phobia and mood disorders in the US National Comorbidity Survey.

BACKGROUND: General population data were used to study co-morbidities between lifetime social phobia and mood disorders. METHODS: Data come from the US National Comorbidity Survey (NCS). RESULTS: Strong associations exist between lifetime social phobia and major depressive disorder (odds ratio 2.9), dysthymia (2.7) and bipolar disorder (5.9). Odds ratios increase in magnitude with number of social fears. Reported age of onset is earlier for social phobia than mood disorders in the vast majority of co-morbid cases. Temporally-primary social phobia predicts subsequent onset of mood disorders, with population attributable risk proportions of 10-15%. Social phobia is also associated with severity and persistence of co-morbid mood disorders. CONCLUSIONS: Social phobia is a commonly occurring, chronic and seriously impairing disorder that is seldom treated unless it occurs in conjunction with another co-morbid condition. The adverse consequences of social phobia include increased risk of onset, severity and course of subsequent mood disorders. Early outreach and treatment of primary social phobia might not only reduce the prevalence of this disorder itself, but also the subsequent onset of mood disorders.

Sex differences in minor psychiatric morbidity.

This monograph is concerned with some epidemiological observations of minor psychiatric morbidity. Differences in rates of specific disorders have historically formed a crucial part of epidemiological enquiry. Sex differences in the prevalence of minor affective disorders have been demonstrated in studies of populations in treatment and in community populations, and have been variously ascribed to constitutional or environmental factors. A review of the literature exposes the methodological problems of measurement and study design, and the conflicting nature of the findings. Efforts have recently concentrated on establishing the social factors important in the aetiology of minor affective disorder without adequate exclusion of constitutional factors. The importance of life events, chronic social stress and inadequate social supports in the aetiology of minor affective disorder has been demonstrated, but the variance explained by such factors is small, reinforcing the view that constitutional factors of some kind are likely to be of importance. The evidence for a genetic contribution to minor affective disorder is tenuous, but there is circumstantial evidence that changes in gonadal hormones are linked to mood changes in women. Until further evidence is available this must remain a powerful possibility in the genesis of sex differences in minor affective disorder. This investigation used epidemiological methods to assess whether there is a sex difference in the constitutional vulnerability of the male and female phenotype to minor psychiatric morbidity. In order to minimize the effects of environment and of sex roles and stereotypes as far as possible, a sample of relatively homogeneous employed men and women (drawn from a population of executive officers in the Home Office) was studied. The data obtained from this population of men and women of similar age, education, occupation and social environment were compatible with the null hypothesis that there is no sex difference in the prevalence of minor psychiatric morbidity, or its outcome in such a homogeneous group. However, women did report significantly more somatic symptoms than men. The second hypothesis, that there is a substantial sex difference in the self-perception of illness, illness behaviour and sickness absence in individuals with minor psychiatric morbidity among a homogeneous group of men and women of similar age, education and occupation, and subject to similar levels of social stress and support, received only partial support from the findings of the study.(ABSTRACT TRUNCATED AT 400 WORDS)
