Genetic amniocentesis in multiple gestations.
Thirty-one genetic amniocenteses involving multiple gestations were performed in the genetics unit between 1976 and 1982. Three sets of triplets were included. Precise locations of the sacs were determined using real-time ultrasonography and successful sampling of all sacs was accomplished. Spontaneous abortions occurred in two normal twins and one normal triplet gestation. Two therapeutic abortions were performed for fetal abnormalities. Two cases of discordance for trisomy 21 (one twin and one triplet) were allowed to continue; the twin case terminated at 25 weeks' gestation with neonatal deaths and the triplets are alive and well.

Third trimester ultrasound diagnosis of intestinal atresia following clinical evidence of polyhydramnios.
Five cases of intestinal atresia were diagnosed using real-time ultrasonography following clinical evidence of polyhydramnios. No correlation was noted between ultrasound findings and the severity of the lesions. Two of the five babies died at 35 and 77 days respectively. Prematurity and presence of other abnormalities were factors in the deaths.

Frustrating patients: physician and patient perspectives among distressed high users of medical services.
OBJECTIVE: To identify differences between patients viewed as frustrating by their physicians and those considered typical and satisfying. DESIGN: This cross-sectional observational study focused on psychologically distressed high users of medical services. Frustrating patients were compared with typical and satisfying patients, using data from patient questionnaires, physician assessments, structured psychiatric interviews, and computerized utilization records. SETTING: Group Health Cooperative of Puget Sound, a large health maintenance organization. PATIENTS/PARTICIPANTS: Study patients were in the top decile for ambulatory visits, and bad elevated scores for anxiety, depression, and somatization. Among the 339 patients invited to participate in the study, 251 agreed, and 228 were rated by their physicians. MAIN RESULTS: A substantial proportion (37%) of the high users were viewed as frustrating by their physicians. Physicians' ratings of physical disease severity did not differ among the groups, but frustrating patients rated their own health status less favorably and reported more somatic symptoms and disabilities. The frustrating group utilized more medical services than did other distressed high utilizers. All three groups had a high prevalence of mental disorders. However, frustrating patients had higher rates of somatization and generalized anxiety disorder. CONCLUSIONS: Physicians and their frustrating patients had contrasting views of the patients' illnesses. The best predictors of physician frustration were somatization and increased medical service utilization. There is need for further research and clinical attention concerning optimal clinical management for patients with somatization.

An evaluation of acid-base changes following aortic cross-clamping using transcutaneous carbon dioxide monitoring.
To investigate the cause of acidosis following release of an aortic cross-clamp, we measured tissue PCO2 using a transcutaneous (TC) CO2 monitor placed below the level of the cross-clamp in 10 patients undergoing aortic arch surgery. Following placement of the aortic cross-clamp, the TC CO2 value from the lower extremity increased from 41 +/- 4 to 92 +/- 41, whereas there was no change in the TC CO2 value from the upper extremity. With release of the cross-clamp, end-tidal CO2 increased by 6.2 +/- 1.9 mmHg, the upper TC CO2 increased by 8.4 +/- 4.8 mmHg, and the lower extremity TC CO2 value returned to baseline. During cross-clamping, there was an increase in the base deficit of 4.3 +/- 2.9 when comparing the baseline arterial blood gas value with the one obtained after cross-clamp release (p = 0.0004). These data demonstrate that the acidosis occurring during aortic cross-clamping is a mixed metabolic and hypercarbic acidosis. Appropriate treatment includes the provision of adequate minute ventilation to ensure CO2 removal and the use of sodium bicarbonate based on the degree of metabolic acidosis demonstrated by arterial blood gas analysis.

Adult attention-deficit hyperactivity disorder: assessment guidelines based on clinical presentation to a specialty clinic.
Of 143 adults presenting for attention-deficit hyperactivity disorder (ADHD) evaluation, 46 (32%) clearly met diagnostic criteria, 46 (32%) clearly did not meet diagnostic criteria, and another 51 (36%) with current ADHD-like features did not meet criteria due to either a lack of childhood history and/or complicating severe psychiatric or substance abuse comorbidity. The three groups were similar in demographics, psychiatric diagnosis, psychiatric symptom severity, and functional impairment. Compared with the group not meeting ADHD criteria, patients with ADHD had more frequent histories of learning disability in childhood, poorer reading scores on the Wide-Range Achievement Test (WRAT), poorer scores on the Continuous Performance Test (CPT), and higher scores on the Wender-Utah Rating Scale (WURS) for ADHD. Patients in the ambiguous ADHD category had higher rates of current substance abuse than the other two groups. While this group resembled the non-ADHD group in having a low incidence of learning disability and normal reading scores, their poor performance on the CPT and high scores on the WURS more closely resembled those of ADHD patients. These findings suggest that there are a few rating scales, testing instruments, and lifetime history characteristics that help to clarify the difficult diagnostic distinction between adult patients who do and do not have ADHD.

Severity of somatization and its relationship to psychiatric disorders and personality.
Medical patients' (75 with chronic fatigue complaints, 61 with dizziness, and 88 with disabling tinnitus; N = 224) current and past psychiatric diagnoses and personality characteristics were assessed to determine if they could independently explain the number of medically unexplained physical symptoms that the patients had experienced. Cloninger's Tridimensional Personality Questionnaire (TPQ) and the Diagnostic Interview Schedule based on DSM-III-R were used to assess the personality and psychiatric diagnoses, respectively. The results revealed that the number of lifetime medically unexplained symptoms were significantly, independently, and positively related to increasing numbers of current and past anxiety and depressive disorders and to the harm avoidance dimension of the TPQ. In a second analysis, the "worry/pessimism" and "impulsiveness" subscales were positively related to the number of medically unexplained symptoms. The results suggest that somatization is associated with current and past history of psychiatric illnesses and harm avoidance in this sample of medical patients.

Psychiatric diagnoses and sexual victimization in women with chronic pelvic pain.
The authors evaluated 100 women scheduled for diagnostic laparoscopy (50 for chronic pain, 50 for tubal ligation or infertility evaluation) using structured psychiatric, family history, and sexual trauma interviews. Laparoscopy reports were blindly rated by a gynecologist. Compared with the nonpain group, the women with chronic pelvic pain had significantly higher current and lifetime rates of psychiatric disorders, as well as childhood and adult sexual victimization. They reported significantly higher mean numbers of somatization symptoms, but no significant differences in objective laparoscopic findings. Psychiatric disorders and sexual victimization are common in women with chronic pelvic pain and should be considered in the evaluation and treatment of these patients.

Neuroticism and extraversion as predictors of health outcomes in depressed primary care patients.
Depressed primary care patients (N = 217) were assessed to determine if certain personality characteristics predict health domains independent of chronic disease, demographics, depression, and psychiatric diagnoses. Eleven health variables were used to create three outcome factor scores: disability (e.g., days missed work); somatization (e.g., medically unexplained symptoms); and subjective pain (severity, interference). Neuroticism explained significant variance in all health outcomes independent of the other predictors. Depression and neuroticism interacted in the disability and pain models. Depression was related to health in neurotic patients, while in the absence of neuroticism, little relation between depression and health was observed. Neuroticism may explain why persons with similar health problems have differing levels of disability, pain, and somatization.

Depression in coronary heart disease. What is the appropriate diagnostic threshold?
The purpose of this study was to determine the threshold at which depression becomes important for the daily functioning of patients with heart disease. Data from a 1-year prospective cohort study of health maintenance organization patients undergoing coronary angiography for coronary heart disease were analyzed for differences in a standardized composite measure of functioning. Patients with major depression (N = 19) and patients with minor depression (N = 28) were significantly more functionally impaired at baseline and at 1-year follow-up than those with no depression (N = 110). The major and minor depression groups did not differ significantly. The significance of the depression group differences was reduced, but not eliminated, when controlling for differences in reported heart symptoms.

Somatic complaints among pregnant women cared for in obstetrics: normal pregnancy or depressive and anxiety symptom amplification revisited?
Despite the extensive research documenting the significance of medically unexplained somatic symptoms in primary care patients, few studies have examined somatic symptoms as a predictor of depressive and anxiety disorders among pregnant women cared for in Obstetrics. We utilized the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire (PHQ) to assess current depressive and anxiety disorders and self-reported somatic symptoms among 186 women receiving prenatal care. We examined the bivariate relationships between depressive and anxiety disorders and mean number of somatic symptoms. Linear regression analyses assessed the unique association between maternal depression, anxiety and somatic symptoms, while controlling for selected demographics and maternal medical risk. Twenty three percent (N=43) of women met screening criteria for depressive and/or anxiety disorders. Women with depression and/or anxiety were significantly more likely to report somatic symptoms (mean=7.1, SD=2.6) compared to women without depression or anxiety (mean=5.0, SD=2.6) [t(df)=4.54(184), P<.001]. This association persisted in multivariate models. Our findings suggest that antenatal depressive and anxiety disorders are associated with an amplification of physical symptoms of pregnancy. Eliciting and tracking somatic symptoms during prenatal visits could potentially improve detection of depressive and anxiety disorders in the obstetrical sector.

Infectious mononucleosis: psychological symptoms during acute and subacute phases of illness.
Although anecdotal reports suggest that anxiety and depressive disorders may be precipitated by acute infectious mononucleosis (AIM), there are few population-based studies measuring distress and psychiatric disorder during and after infection. The purpose of this research was to study the prevalence of psychiatric disorders and psychological distress in patients with AIM at initial infection and over the subsequent 6 months. In addition, we examined the correlation of baseline biopsychosocial factors with distress at 2 and 6 months postillness. A population-based cohort with AIM was surveyed at initial infection and at 2- and 6-month follow-up visits. Measures included physical and laboratory examinations, trait and state measures of psychological and somatic distress, locus of control, social support, and functioning. Patients also received a structured psychiatric interview during the initial infection. Although transient psychological distress was common during acute infection, few patients met criteria for DSM-III-R psychiatric illness. Greater distress at 2 months was associated with significantly lower social functioning in the month prior to diagnosis and higher aspartate aminotransferase (SGOT/AST) levels, less confidence in the physician and health care system (locus of control), and less severe physical symptoms of AIM at baseline. Greater distress at 6 months was associated with an increased number of adverse life events in the 6 months after developing AIM and more days of reduced activity in the 2 weeks prior to the onset of AIM. This population-based study suggests that few subjects develop DSM-III-R psychiatric disorders with AIM. Both biological and psychosocial factors are highly correlated with psychosocial distress at 2 months, whereas psychosocial factors are more important at 6-month follow-up.

Mammary gland architecture as a determining factor in the susceptibility of the human breast to cancer.
The developmental pattern of the breast can be assessed by determining the composition of the breast in specific lobular structures, which are designated as lobules type 1 (Lob 1), lobules type 2 (Lob 2), and lobules type 3 (Lob 3), with Lob 1 being the less developed and Lob 3 being the most differentiated or with the highest number of ductules per lobular unit. In the present work, the patient population consisted of three groups of women who underwent surgical procedures: The first group included women who underwent reduction mammoplasty (RM) for cosmetic reasons. The second group included women who underwent prophylactic subcutaneous mastectomy after genetic counseling for either carrying the BRCA-1 gene or belonging to a pedigree with familial breast cancer (FAM), and the third group included women who underwent modified radical mastectomy (MRM) for the diagnosis of invasive carcinoma. The RM group consisted of 33 women, of whom 9 were nulliparous and 24 were parous. The FAM group consisted of 17 women, of whom 8 were nulliparous and 9 were parous. The MRM group consisted of 43 women, of whom 7 were nulliparous and 36 were parous. The analysis of the lobular composition of all of the samples from the RM group, which is considered the control group, revealed that Lob 1 represented 22%, Lob 2 represented 37%, and Lob 3 represented 38%, whereas the tissue examined from the FAM and MRM groups contained a preponderance of Lob 1 at 48% and 74%, respectively, over Lob 3, which was 10% and 3%, respectively. When the results of the analysis of breast tissue were separated according to the pregnancy history of the donor, it was found that in the control group or RM, there was a significant difference in lobular composition. Nulliparous women of the RM group showed a preponderance of Lob 1 (46%) over parous women, which contained only 17%, whereas the percentage of Lob 3 in the nulliparous group was significantly lower (7%) than the parous group (48%). In the breast tissues obtained from FAM and MRM, no significant differences in lobular composition were observed, as all of the samples contained a higher concentration of Lob 1, independent of the pregnancy history. The breast tissue of FAM and MRM of parous women had a developmental pattern that was similar to that of nulliparous women of the same group and that was less developed than the breast of parous women of the control group. An important difference between the Lob 1 of the FAM group versus the control (RM) and the MRM group was that most of these lobules had thin ductules with an increase in hyalinization of the intralobular stroma manifested in the whole-mount preparation as an alteration in the branching pattern. The data suggest that the breast tissue of women with invasive cancer, as well as those from a background of familial breast cancer, have an architectural pattern different from the control or normal tissues and that the BRCA-1 or related genes may have a functional role in the branching pattern of the breast during lobular development, mainly in the epithelial stroma interaction.

Chronic neurologic sequelae to cholinesterase inhibition among agricultural pesticide applicators.
To test the hypothesis that chronic neurologic sequelae are associated with cholinesterase depression short of frank organophosphate poisoning, we compared 45 male subjects who had a history of moderate cholinesterase inhibition with 90 male subjects who had neither past cholinesterase inhibition nor current pesticide exposure. Cholinesterase-inhibited subjects were defined as having had a history of (a) red blood cell cholinesterase at 70% or less of baseline or (b) plasma cholinesterase at 60% or less of baseline absent symptoms of frank poisoning. In the subject comparison evaluation, only 1 of 27 neurologic tests (i.e., serial digit performance) was significant statistically, but it was opposite of the direction hypothesized. In a companion study for which the same battery of neurologic tests and the same subjects were used, neurologic sequelae were related to high exposures among subjects who sought treatment for organophosphate poisoning. The data in the current study, in which the subjects experienced lower exposures short of frank poisoning, provide some evidence that preventing acute organophosphate poisoning also prevents neurologic sequelae.

Life events as correlates of burden in spouse caregivers of persons with Alzheimer's disease.
The first goal of this study was to examine the occurrence and appraised distress of 20 stressful life events in 175 spouse caregivers (mean age = 68.6) of persons with Alzheimer's disease and 92 age- and gender-matched controls (mean age = 68.5). The second goal was to determine whether, in the caregivers, life stressors were related to burden after controlling for caregiver age, gender, satisfaction with social supports, and care-recipient cognitive and activities of daily living functioning. Caregivers and controls had similar occurrences and appraisals for all but 3 events, which occurred more frequently in caregivers (i.e., "changes in your spouse's health," "changes in your relationship with your spouse," and "changes in the way you friends and family treat you (social relations)"). Only "changes in finances" was appraised as more distressing by caregivers. Six events explained burden in the regressions: "victim of crime," "age discrimination," "serious family arguments (not including spouse)," "change in caregiver's health," "trouble with Medicaid/Medicare or Social Security," and "move to retirement home (associated with less burden)." Age discrimination was related to burden only for the caregivers of the most impaired care recipients. Also, caregivers who experienced health problems and who had been victims of crimes were the most burdened. Caregivers are not immune to problems experienced by older adults, and these problems may exacerbate caregiver burden. Clinicians should consider the overall context of a caregiver's life when evaluating burden.

Psychosocial factors associated with cardiovascular reactivity in older adults.
This study examined associations of psychosocial factors with cardiovascular reactivity in two groups of men and women--spouse caregivers of individuals with Alzheimer's disease (M age = 69.4 N = 82) and controls (M age = 68.5, N = 78) group-matched for age and gender. Cardiovascular responses to an emotional task (speech sample about one's spouse) yielded higher systolic and diastolic blood pressures (SBP, DBP) than a spoken cognitive task, which in turn yielded higher BPs and heart rate (HR) than the baseline rest period. HR was greater in response to the two tasks than in response to the baseline period, but it did not differ across tasks. Regression models of SBP, DBP, and HR reactivity in response to the two tasks demonstrated that after controlling for hypertension and gender, combinations of hostility, anger expression, avoidance coping, Type A behavior and Expressed Emotion (criticism) explained more reactivity in response to the emotional (8-12%) than the cognitive task (4-7%). Caregivers were more reactive than controls only if they were hypertensive. Psychosocial factors may be as important in explaining reactivity in older adults as in younger adults.
