Measures of psychopathology in children with complex partial seizures and primary generalized epilepsy with absence

OBJECTIVE

This investigation examined psychopathology in 48 children with complex partial seizures (CPS), 39 children with primary generalized epilepsy with absence (PGE), and 59 nonepileptic children, aged 5 to 16 years, by comparing the Child Behavior Checklist (CBCL) and the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS).

METHOD

The CBCL was completed by parents and the K-SADS was administered to both parent and child.

RESULTS

The CBCL identified psychopathology in 26% and the K-SADS in 51% of the CPS and PGE patients (kappa = 0.32). The CPS and PGE groups had significantly higher mean CBCL scores, as well as higher rates of psychiatric diagnoses and symptoms of psychopathology, compared with the nonepileptic group. However, the CPS and PGE groups did not differ in these measures. Within each patient group, Full Scale IQ, but not seizure control, was associated with these measures of psychopathology.

CONCLUSION

These findings suggest that the K-SADS identifies more children with psychopathology than the CBCL in children with CPS and PGE.

Recurrent epithelial ovarian carcinoma: a randomized phase III study of pegylated liposomal doxorubicin versus topotecan

PURPOSE

To compare the efficacy and safety of pegylated liposomal doxorubicin (PLD) and topotecan in patients with epithelial ovarian carcinoma that recurred after or didn't respond to first-line, platinum-based chemotherapy.

PATIENTS AND METHODS

Patients with measurable and assessable disease were randomized to receive either PLD 50 mg/m(2) as a 1-hour infusion every 4 weeks or topotecan 1.5 mg/m(2)/d for 5 consecutive days every 3 weeks. Patients were stratified prospectively for platinum sensitivity and for the presence or absence of bulky disease.

RESULTS

A total of 474 patients were treated (239 PLD and 235 topotecan). They comprised the intent-to-treat population. The overall progression-free survival rates were similar between the two arms (P =.095). The overall response rates for PLD and topotecan were 19.7% and 17.0%, respectively (P =.390). Median overall survival times were 60 weeks for PLD and 56.7 weeks for topotecan. Data analyzed in platinum-sensitive patients demonstrated a statistically significant benefit from PLD for progression-free survival (P =.037), with medians of 28.9 for PLD versus 23.3 weeks for topotecan. For overall survival, PLD was significantly superior to topotecan (P =.008), with a median of 108 weeks versus 71.1 weeks. The platinum-refractory subgroup demonstrated a nonstatistically significant survival trend in favor of topotecan (P =.455). Severe hematologic toxicity was more common with topotecan and was more likely to be associated with dosage modification, or growth factor or blood product utilization.

CONCLUSION

The comparable efficacy, favorable safety profile, and convenient dosing support the role of PLD as a valuable treatment option in this patient population.

Conversational repair in pediatric epilepsy

This study examined if children with complex partial seizures disorder (CPS) and primary generalized epilepsy with absence (PGE) were impaired in the use of self-initiated repair during a conversation compared to normal children. Transcriptions of speech samples of 92 CPS, 51 PGE, and 65 normal children, ages 5-16 years, were coded for self-initiated repair according to Evans (1985). The WISC-R, a structured psychiatric interview, and seizure-related information were obtained for each child. We found impaired use of repair in both the CPS and PGE groups compared to the normal subjects. The CPS patients, particularly those with a temporal lobe focus, overused self-initiated corrections of referents and syntax compared to the PGE and normal subjects. The CPS and PGE patients with frontal lobe involvement underused fillers compared to the normal children. These findings provide additional evidence that both CPS and PGE impact the ongoing development of children's communication skills.

Parents' perceived benefits and barriers of adolescents' diabetes self-management: part 2

Knowledge is limited about parents' decision making regarding adolescents' assumption of diabetes management. This study's purpose was to identify parents' perceived benefits and barriers about this process. We interviewed 17 parents of adolescents with type I diabetes. Questions were adapted from Janis and Mann's (1977) decisional balance sheet. Interviews were audiotaped and transcribed verbatim. Descriptive expressions were identified and categories inductively generated. Inter-rater agreement was initially 85% and was 100% after discussion of disagreements. Parents' perceived benefits for themselves were relief from burden and knowledge and confidence and/or pride in adolescents' abilities. Their perceived benefits for their sons and daughters were also twofold: knowledge and/or confidence in abilities and freedom, independence, and/or control. Parents perceived barriers for themselves were loss of control, authority, and supervision, dealing with consequences. and expression of lack of barriers. Their perceived barriers for their sons and daughters were burden of responsibility and also lack of barriers. Understanding parents' perceived benefits and barriers would be beneficial to health care professionals when working with parents, because decision making related to the transfer of diabetes management to their adolescent sons and daughters is crucial to the success of its management.

Development and validation of the Parental Intrusiveness Rating Scale among bulimic and comparison women

OBJECTIVE

Based on hypotheses generated during clinical interviews with 80 women with a lifetime history of bulimia nervosa (BN), we designed an instrument for assessing the extent to which women with BN report parental intrusiveness and breakdown of appropriate role boundaries during their adolescent development.

METHOD

Through an iterative process of item generation and scale administration, the Parental Intrusiveness Rating Scale (PIRS), consisting of 20 maternal items and 20 paternal items, was developed. Maternal subscales include Invasion of Privacy, Jealousy and Competition, and Overconcern with the Daughter's Eating, Weight, and Shape. Paternal subscales include Invasion of Privacy, Seductiveness, and Overconcern with the Daughter's Eating, Weight, and Shape. We validated the instrument using a subset of the above BN and comparison women (ns = 55 and 33, respectively), as well as an independent sample of women with BN and college comparison subjects (ns = 31 and 540, respectively).

RESULTS

Parental intrusiveness scores were significantly positively correlated with disturbed relationships in the family of origin of our initial cohort. Reliability analyses, both test-retest and item-scale correlations, revealed adequate to strong statistical associations in the combined sample.

CONCLUSION

The PIRS promises to enrich our understanding of problematic parental behaviors among women who develop BN and allows us to broaden the conceptualization of familial risk factors for this disorder.

Radiotherapy in poor risk patients with stage I cancer of the endometrium: results of not giving external beam radiotherapy

Poor prognosis (poorly differentiated and/or deep myometrial invasion) Stage I endometrial cancer can have a relapse rate as high as 50%. Traditionally, most clinical oncologists treat these patients with external beam radiotherapy after surgery but there is no evidence to show that this improves survival. The retrospective study looks at the results of not giving external beam radiotherapy in 25 consecutive patients and compares the results with a group of 13 consecutive patients who did have such treatment. The two groups were comparable with regard to age, degree of differentiation and degree of invasion. Survival was comparable in the two groups. There is no evidence of any obvious decrease in survival from withholding external beam radiotherapy, but this was not a prospective randomized controlled trial. This study illustrates that it is essential that the Medical Research Council ASTEC trial should be supported because this will determine the true place of external beam radiotherapy in such patients.

Adolescents' perceived benefits and barriers related to diabetes self-management--Part 1

Knowledge is limited about adolescents' decision making regarding their assumption of diabetes management from parents. This study's purpose was to identify adolescents' perceived benefits and barriers about this process. Sixteen adolescents with type 1 diabetes were interviewed. Questions were adapted from the Janis and Mann (1977) decisional balance sheet. Interviews were audiotaped and transcribed verbatim. Descriptive expressions were identified and categories inductively generated. Adolescents' perceived benefits for themselves were having knowledge of or confidence in self-management abilities, more freedoms, and approval of others. They perceived benefits for parents as relief from responsibility, stress, and worry. Burden of responsibility was perceived as a barrier to adolescents for self-management. Adolescents perceived barriers for parents as worry/guilt and loss of control. Interrater agreement was initially 74%. Categories with disagreements were recategorized by interraters and then there was 100% agreement. Understanding adolescents' perceptions would be beneficial to their health care professionals.

Childhood schizophrenia: responsiveness to questions during conversation

OBJECTIVES

This study characterized further the communicative deficits associated with childhood-onset schizophrenia. It examined the use of speech functions that involve responses to Yes/No and Wh- questions in children with schizophrenia and normal children during conversation. It also ascertained the relationship of these speech functions with cognition and thought disorder.

METHOD

Speech function variables, formal thought disorder, and cohesion were coded in 32 schizophrenic and 34 normal children, aged 5.6 to 12.4 years, from speech samples elicited with the Story Game.

RESULTS

The schizophrenic children were significantly more impaired in the use of speech functions than the normal children. Other than the association of a subset of the speech functions with distractibility and loose associations, the speech function measures were unrelated to cognitive and thought disorder measures.

CONCLUSIONS

Speech function analysis detects communication deficits not captured by thought disorder measures in children with schizophrenia.

Thought disorder in childhood schizophrenia: replication and update of concept

OBJECTIVES

To examine whether measures of thought disorder differentiated schizophrenic from normal children and to examine the relationship of these measures with developmental and cognitive factors.

METHOD

The speech samples of 88 schizophrenic and 190 normal children, aged 9 to 13 years, were coded with the Kiddie Formal Thought Disorder Rating Scale and Halliday and Hassan's analysis of cohesion.

RESULTS

Above and beyond differences in mental age, gender, and neuroleptic status, the patients had significantly more formal thought disorder (FTD) and cohesive deficits than the normal children matched by mental age. The younger schizophrenic and normal children had significantly more thought disorder than the older children with these diagnoses. Combined FTD and cohesion scores correctly identified 76% of schizophrenic and 88% of normal children with little variability across mental age. The thought disorder measures generated 2 independent components: FTD and cohesion.

CONCLUSIONS

Thought disorder measures that include both FTD and cohesion provide a quantitative diagnostic tool of childhood-onset schizophrenia.

Prepulse inhibition of startle, intelligence and familial primary nocturnal enuresis

Previous studies have shown a significant reduction of prepulse inhibition of startle in boys with primary nocturnal enuresis. Those enuretic boys who had higher IQs showed less prepulse inhibition. This study evaluates the association of prepulse inhibition and IQ in primary nocturnal enuresis in respect to family history of primary nocturnal enuresis. Prepulse inhibition of startle was studied in 83 boys with primary nocturnal enuresis and 57 non-enuretic boys using an interval of 120 ms between the onset of a 75 dB 1000 Hz tone and a 104 dB noise burst. Of the boys with primary nocturnal enuresis, 56 had a family history of primary nocturnal enuresis and 27 had no family history (no first-degree relative). Of the 57 non-enuretic boys, 42 also had no family history (no first-degree relative) of primary nocturnal enuresis, while 15 did have a positive family history. Associations between prepulse inhibition and IQ scores were compared among these four groups. Strong and significant associations between prepulse inhibition deficit and higher IQ scores in the enuretic group with familial primary nocturnal enuresis were unique in comparison to the other groups.

CONCLUSIONS

The strong heritabilities of primary nocturnal enuresis, intelligence and prepulse inhibition suggest genetic mediation of the association of prepulse inhibition with intelligence in familial primary nocturnal enuresis.

Infantile spasms: the development of nonverbal communication after epilepsy surgery

The postoperative development of nonverbal communication was studied in 29 children, aged 18.2 (SD = 11.54) months, who underwent multilobar resection or hemispherectomy for intractable symptomatic infantile spasms (IS). Using the Early Social Communication Scale, the IS subjects had little, if any, social interaction, joint attention or behavior regulation before surgery. After a mean follow-up of 24 months, most of the children continued to have delayed nonverbal communication skills compared to normal children. Seizure-related, surgical and cognitive factors were unrelated to the postsurgical development of nonverbal communication. The children with right-sided surgery had a statistically significant increase in the use of social interaction but not in other gestural behaviors. Removal of the frontal lobe was not related to the nonverbal communication outcome. The study's findings suggest that impaired use of nonverbal communication might be a feature of surgically treated children with medically intractable IS.

Vineland Adaptive Behavior Scale scores as a function of age and initial IQ in 210 autistic children

Human growth modeling statistics were utilized to examine how Vineland Adaptive Behavior Scale (VABS) scores changed in individuals with autistic disorder as a function of both age and initial IQ. Results revealed that subjects improved with age in all domains. The rate of growth in Communication and Daily Living Skills was related to initial IQ while rate of growth in Social Skills was not. Results should provide hope for parents and further support for the importance of functional social-communication skills in the treatment of autism.

Natural human interferon-alpha administered orally as a treatment of bovine respiratory disease complex

Natural human interferon-alpha (nHuIFN-alpha) from three sources was given orally to 368 calves experiencing a natural outbreak of bovine respiratory disease complex (BRDC). In one study, 200 calves were given one treatment daily for 3 days of placebo or 20, 200, or 2,000 IU of nHuIFN-alpha before shipment. Calves treated with 20 or 200 IU had a significant (p < 0.05) weight gain benefit for the first 21 days in the feedlot, if they had rectal temperatures <40 degrees C when treated with nHuIFN-alpha. In a second trial, 168 mixed-breed calves (five groups randomized to 31-36 calves/group) were treated with one dose of placebo or 200 or 400 IU of nHuIFN-alpha after shipment to the feedlot. Using this regimen, a dose of 200 IU per calf significantly (p < 0.08) decreased the number of sick calves per group and delayed development of BRDC. Results of these studies demonstrate that oral administration of nHuIFN-alpha, which may partially mimic the nasally secreted IFN response reported during BRDC, may be beneficial in cattle.

When the earth stops shaking: earthquake sequelae among children diagnosed for pre-earthquake psychopathology

OBJECTIVE

To examine risk and protective processes for posttraumatic stress reactions and negative sequelae following the Northridge earthquake (EQ) among youths diagnosed for pre-EQ psychopathology.

METHOD

Symptoms of posttraumatic stress disorder (PTSD), depression, general anxiety, and social impairment were evaluated using telephone interviews among 66 children participating in a family-genetic study of childhood-onset depression at the time of the EQ.

RESULTS

Significant predictors of PTSD symptoms 1 year after the EQ included perceived stress and resource loss associated with the EQ, a pre-EQ anxiety disorder, and more frequent use of cognitive and avoidance coping strategies. PTSD symptoms were associated with high rates of concurrent general anxiety symptoms, depressive symptoms, and social adjustment problems with friends. The only significant correlation between sibling scores was on measures of sibling reports of objective exposure.

CONCLUSIONS

Preexisting anxiety disorders represent a risk factor for postdisaster PTSD reactions. Postdisaster services need to attend to the needs of these youths as well as those of youths experiencing high levels of subjective stress, resource loss, and/or high exposure. That children within families show significant variation in postdisaster reactions underscores the need for attention to individual child characteristics and unshared environmental attributes.

Prepulse inhibition of startle and the neurobiology of primary nocturnal enuresis

BACKGROUND

Children with primary nocturnal enuresis (PNE) wet the bed during all stages of sleep and irrespective of state of arousal, suggesting that during sleep, when voluntary, i.e., cortical control, is not available, the signal from the distended bladder is not registered in the subcortical centers inhibiting micturition. Deficient prepulse inhibition (PPI) of startle has been reported in PNE. This study evaluates the association of this PPI deficit in PNE with comorbidity with attention-deficit hyperactivity disorder (ADHD) and with intelligence.

METHODS

Prepulse modulation of startle was studied in 96 boys with PNE and 105 nonenuretic boys using intervals of 60, 120, and 4000 msec between the onset of a 75-dB 1000-Hz tone and a 104-dB noise burst. Thirty-one percent of the enuretic and 36% of the nonenuretic boys were diagnosed with ADHD.

RESULTS

After adjustment for presence or absence of ADHD, lower or higher IQ, age, and unmodulated startle amplitude, there was a significant association between PNE and deficient PPI of startle following the 120-msec prepulse interval. Those enuretic boys who also were ADHD or had higher performance IQs (> or = 110) showed the greatest PPI deficit.

CONCLUSIONS

A common deficiency of inhibitory signal processing in the brain stem may underlie both deficient PPI and the inability to inhibit micturition in PNE. Strong familiarity for PNE, ADHD, and intelligence suggests a possible genetic mediation of these effects.

Continuous-processing related ERPS in adult schizophrenia: continuity with childhood onset schizophrenia

BACKGROUND

Previous work with schizophrenic children disclosed deficits on two continuous performance tests (CPTs) and ERP indices of reduced attentional resource allocation.

METHODS

The two CPTs were administered to adult schizophrenics and matched control subjects. The simple CPT required only that the subject respond whenever the target digit was displayed. The complex version required a response whenever any digit was displayed on two successive trials. Event-related potentials (ERPs) were recorded during task performance.

RESULTS

Schizophrenics had fewer hits on both CPT versions, showed a greater drop in performance from the simple to the complex CPT, and took longer to respond than controls. The processing negativity (Np) showed a greater amplitude increase from nontarget to target in normals than in schizophrenics, and the overlapping P2 component was more negative in normals. P3 latency was longer in schizophrenics, but P3 amplitude did not differ.

CONCLUSIONS

Group performance and processing negativity effects replicated those from an earlier study of schizophrenic and normal children administered the same versions of the CPT, suggesting similar abnormalities in the allocation and modulation of information processing resources.

Ambulatory blood pressure, heart rate, and neuroendocrine responses in women nurses during work and off work days

OBJECTIVE

This study examined women's cardiovascular and neuroendocrine responsiveness to work.

METHODS

Ambulatory blood pressure (BP) and heart rate (HR) were recorded over 24-hour periods on 2 work and 2 off days during the luteal and follicular phases of the menstrual cycle in 138 registered nurses, aged 25 to 50 years. Urinary catecholamines and cortisol were measured for day and night periods.

RESULTS

During waking hours systolic BP (SBP), HR, and epinephrine were higher on work than off days. Diastolic BP (DBP) and HR were highest at work. Nurses scoring high on job demands had elevations in daytime SBP, daytime HR only on work days, and nighttime epinephrine on work days. Compared with those with short work histories, nurses employed longer had consistently higher norepinephrine levels during days and nights, and higher nighttime DBP during off days. In unmarried nurses compared with married nurses, nighttime cortisol was lower during all 4 days and norepinephrine was lower during days off. All findings were independent of actigraph-recorded activity.

CONCLUSIONS

Although the work environment leads to increased activity of the cardiovascular and sympathoadrenal medullary system in healthy women, the effects are modified by the woman's domestic role, by the length of her employment, and by the demands of her job.

Cerebellar vermis lobules VIII-X in autism

1. The aim was to investigate cerebellar vermis cross-sectional area in a group of high-functioning autistic children and normal control children. 2. Cerebellar vermis area measurements were completed on MRI scans from 8 autistic children (mean age 12.5 +/- 2.2, mean IQ 83.3 +/- 11.9) and 21 normal children (mean age 12.0 +/- 2.8, mean IQ 115 +/- 11). 3. The area of cerebellar vermis lobules VIII-X was significantly smaller in the autistic children than in the normal control subjects. ANCOVA demonstrated a confounding effect of IQ on these results. 4. Larger studies of autistic and normal subjects will be needed to assess the relationship between cerebellar abnormalities, autistic symptoms and IQ.

Prevention of vaginal stenosis in patients following vaginal brachytherapy

The assessment of patients following intracavitary irradiation administered as part of the treatment of gynaecological malignancy reveals vaginal stenosis in the majority. Vaginal dilators are available for daily insertion in an attempt to prevent the formation of adhesions. However, the design of the dilator neglects the fact that the vagina is the most distensible in the upper third and hence many patients develop stenosis of the upper vagina. Many clinicians have abandoned the use of dilators and instead advise patients to have sexual intercourse to prevent the problem. In 1994, we designed a new vaginal stent, which was given to all patients who had received intracavitary irradiation with full instructions about its use. This stent was designed to suit better the true anatomy of the vagina and hence, with correct use, should prevent vaginal stenosis. A retrospective study was undertaken to look at the incidence of vaginal stenosis and this was compared with the incidence in patients using the new stent. The study revealed that 57% of the patients who were advised to have sexual intercourse had stenosis, whereas 11% of the patients using the stent had evidence of stenosis, which, however, was related to their incorrect use of the stent. In those who used the stent correctly there was no evidence of vaginal stenosis. Details of the design of the stent and the problems relating to those who used the stent incorrectly are presented. The findings of this study strongly support the continued use of this vaginal stent in patients who have undergone intracavitary irradiation as a means of preventing this common complication.

Correlates of first intercourse among women in Jamaica

This study examines retrospective reports of factors anticipated to impact first intercourse in a random sample of 897 Jamaican women, and contributes to our understanding of the relationship between sexual risk, knowledge, and economic and demographic correlates of first intercourse. A relationship between initiation of intercourse prior to the age of consent (16 years) and factors occurring at or around the time of first intercourse was found. Early initiators were more likely to have had less early family stability and to have experienced menarche at a younger age than late initiators. Although early initiators of intercourse were more likely to report lower socioeconomic status, less STD knowledge, and greater numbers of pregnancies, they were no more likely to report more sexual partners than women who engaged in first intercourse after the age of consent, and had a greater number of long-term relationships. Regardless of age of first intercourse, women need to be made aware of the risks of sexual contact so that they can make informed decisions about the consequences of sexual activity. Overall, results are consistent with work conducted in other parts of the Caribbean and America regarding the age at which young women engage in first intercourse. Findings suggest the need for further work exploring expectations at first intercourse such as marriage, economic support, or relationship stability. Implications of these findings are discussed within the context of economic and structural factors that both increase and decrease risks.

Infantile spasms: facial expression of affect before and after epilepsy surgery

This is a longitudinal study of facial expression of affect in 28 children with intractable infantile spasms who underwent epilepsy surgery. After a mean follow-up period of 1.8 years, there was a significant increase in positive affect, a significant decrease in neutral affect, and no change in negative affect during a nonverbal communication paradigm. These findings were unrelated to surgical (i. e., side of surgery, type of surgery) or seizure-related variables (i.e., seizure control, age at onset of illness, duration of illness, change in antiepileptic drugs). Comparison of affect in a subgroup of 16 patients with those of 32 normal subjects suggest a normal age-related increase in the use of positive affect. Both before and after surgery, the patients used the most positive affect while not communicating. They also used significantly more positive affect during while requesting objects or assistance rather than during social referencing. Intractable infantile spasms might be associated with reduction in the facial expression of positive affect and with impaired use during social communication.

Chemotherapy in advanced ovarian cancer: four systematic meta-analyses of individual patient data from 37 randomized trials. Advanced Ovarian Cancer Trialists' Group

The purpose of this systematic study was to provide an up to date and reliable quantitative summary of the relative benefits of various types of chemotherapy (non-platinum vs platinum, single-agent vs combination and carboplatin vs cisplatin) in the treatment of advanced ovarian cancer. Also, to investigate whether well-defined patient subgroups benefit more or less from cisplatin- or carboplatin-based therapy. Meta-analyses were based on updated individual patient data from all available randomized controlled trials (published and unpublished), including 37 trials, 5667 patients and 4664 deaths. The results suggest that platinum-based chemotherapy is better than non-platinum therapy, show a trend in favour of platinum combinations over single-agent platinum, and suggest that cisplatin and carboplatin are equally effective. There is no good evidence that cisplatin is more or less effective than carboplatin in any particular subgroup of patients.

Psychopathology in pediatric complex partial and primary generalized epilepsy

Structured psychiatric interviews were administered to 60 children with complex partial seizure disorder (CPS), 40 children with primary generalized epilepsy with absences (PGE), and 48 control children, aged 5 to 16 years. Significantly more patients with epilepsy had psychiatric diagnoses compared with the control children. There were no statistically significant differences, however, in the number of patients with CPS and PGE with psychiatric diagnoses. Other than a schizophrenia-like psychosis found only in the patients with CPS, the two groups of patients had similar psychiatric diagnoses. The presence of psychopathology was related to significantly lower IQ scores and socioeconomic status, but not to seizure-related factors. These findings suggest that the psychopathology of children with CPS and PGE reflects different subtle neuropsychological deficits.
