Dietary recall method comparison for hospitalized elderly subjects.
A study was made to compare accuracy of the 24-hour recall, including both number of items recalled and amounts of food eaten, for elderly subjects using three methods: I, unaided oral recall, II, printed questionnaire, and III, interview with actual-size color pictures of foods. Sixty hospitalized patients, age 65 to 94, were interviewed. Factors studied for influence on scores were age, sex, educational level, obesity, place of residence, and food preparer. Results showed no significant difference in scores owing to method used, except that 30 subjects above the median age of 76 scored higher on number of items recalled and amounts of food eaten when using the printed questionnaire. None of the demographic factors studied made a significant difference in scores.

Random number generation, psychopathology and therapeutic change.
In two studies, 145 psychiatric inpatients were each asked to say 100 numbers in random order, using the numbers 1 through 10. Compared with normative data, patients with personality disorders and neuroses were not impaired on the random number generation (RNG) task and patients with chronic alcoholism and primary affective disorder, depression, were significantly imparied, but not as much as those with schizophrenia and organic brain syndrome. The relationship between RNG performance and psychiatric diagnosis may reflect severity of disturbed cognitive functioning. The Randomization Index was sensitive to changes in symptoms during hospitalization. The RNG task provides a brief objective measure of those components of attention, cognitive capacity, and short-term memory that are affected by severity of psychopathology.

Social cognition and neurocognitive deficits in schizophrenia.
While research equivocally supports a relationship between social cognition and neurocognition, it is less clear whether social cognition is related to general cognitive functioning or whether specific aspects of social cognition are linked with specific forms of neurocognition. Thus, this study sought to investigate the relationships between various domains of neurocognition and two forms of social cognition, social cue recognition and social problem solving, for 40 people with schizophrenia spectrum disorders. Step-wise multiple regressions found that performance on neurocognitive tests was able to predict 47% and 38% of the variance on measures of the ability to recognize actual and suggested social cues, respectively, and 13% of participants' ability to problem solve in ambiguous social situations. Once estimated intelligence and hospitalization history were controlled, however, neurocognition no longer significantly predicted social problem solving. Executive functioning was uniquely related to each type of social cue recognition, while memory predicted only the recognition of concrete social cues.

Alcoholic Korsakoff's psychosis: a psychometric, neuroradiological and neurophysiological investigation of nine cases.
Nine patients who were admitted to Purdysburn Hospital with a clinical diagnosis of Korsakoff's psychosis were subjected to a series of psychometric tests, to electroencephalography (including P3 auditory evoked potential) and to computerised axial tomography. When compared with controls, the experimental group differed significantly in their psychometric scores in all but the comprehension, vocabulary and digit span subtests of the Wechsler Adult Intelligence Scale. A significant negative correlation was found between scores on the Digit Symbol Subtest and the degree of temporal lobe atrophy (p < 0.01), and between Evans' Ratio and the Paired Associate Learning Test of the Wechsler Memory Scale (p < 0.05). The P3 auditory evoked potential correlated significantly with a poor performance on the Digit Symbol Subtest. In all cases, cortical atrophy co-existed with ventricular dilatation and in none was intellectual impairment confined to short-term memory. The traditional criteria used in arriving at a diagnosis of Korsakoff's psychosis are called into question.

Library collection of the psychosocial publications in consultation-liaison psychiatry.
Psychiatric oncology is a relatively new area, and few comprehensive reviews of related subject matter are available. Thus, the psychiatrists at North Carolina Memorial Hospital who provide liaison to oncology saw the need for a collection of pertinent psychiatric oncology materials that could be studied by faculty, residents, and staff. Such materials would be valuable for patient consultation, lecture preparation, and research background. Their bibliography and library system are discussed here, with a description of the methods of its compilation. The unique features are referenced materials are filed in a centrally available location (departmental library), so that readers have immediate access to them, and bibliographic entries are stored in a small computer in the library, and can be retrieved by topic, title, author. The file currently holds over 340 articles, and is continuously updated. It has been extensively utilized by professionals in this tertiary care teaching hospital as well as in programs across the state.

Behavioral variability within the Brattleboro and Long-Evans rat strains.
Samples of genetically diabetes insipidus (DI) and normal (NO) rats were obtained from American suppliers (Rochester (RO)/DI and NO) and from the colony maintained at Charing Cross Hospital in London (Charing Cross (CC)/DI and NO) to test the hypothesis that the behavior of vasopressin-deficient Brattleboro (DI) and possibly normal Long-Evans rats may vary significantly between different colonies. DI rats of both colonies exhibit longer latencies to emerge into an open field than do NO rats. RO/DI and CC/DI rats acquire goal-approach behavior in a straight runway at similar rates. Following shock in the runway goal box, however, RO/DI rats exhibit marked recovery of running behavior relative to CC/DI rats over the ten post-shock sessions. All DI animals show reductions in goal-approach speed on the first post-shock trial, indicating that the aversive experience is remembered. CC/NO rats acquire goal-approach behavior more slowly than RO/NO rats, but neither NO group shows substantial recovery of goal approach behavior following shock. CC/DI rats showed impaired acquisition of a delayed non-match to sample task relative to RO/DI rats. All groups demonstrated the ability to utilize representational memory to solve the delayed non-match to sample problem once the contingency was learned. The results indicate that DI and normal Long-Evans rats from different colonies show marked differences in behavior. Since differences between DI and normal rats on tests indicating memory are not consistent across colonies, it is unlikely that vasopressin deficit is solely responsible for memory deficiencies. However, vasopressin deficiency may result in changes in temperament.

Hip joint communication with pressure sore: the refractory wound and the role of Girdlestone arthroplasty.
Fifteen patients who underwent Girdlestone arthroplasty (proximal femoral head resection) were reviewed at The Johns Hopkins Hospital and Northwestern Memorial Hospital. Ages ranged from 24 to 57 years (mean 36.7 years). All patients were paraplegics or quadriplegics (C7-L3). All patients presented with signs of sepsis and had evidence of osteomyelitis. Soft-tissue reconstruction was most commonly performed with the vastus lateralis, and no femoral stabilization was used. There were no deaths. Recurrent ulcers at the site of the Girdlestone arthoplasty were found in 23 percent of patients in whom follow-up was possible. No recurrence was noted at the original site in 77 percent with a mean follow-up of 20 months. Additional pressure sores occurred at other nonsurgical sites in six patients at a mean of 23.3 months. Girdlestone arthroplasty with soft-tissue coverage is mandatory for successful treatment of pressure sores with hip joint involvement.

Improving outcome for Western Australian infants with birthweights 500-999 g.
OBJECTIVE: To assess changes in survival and disability in liveborn extremely low birthweight infants (500-999 g) in Western Australia, 1980-1987. DESIGN: Cohort study comparing two periods, 1980-1983 (P1) and 1984-1987 (P2). PARTICIPANTS: All 586 liveborn extremely low birthweight infants in WA in 1980-1987 (266 in P1, 320 in P2). MAIN VARIABLES EXAMINED: Birthweight, place of birth, age at death, neurosensory examination findings and scores on the Griffiths Mental Development Scales or other standardised test results. RESULTS: 482/586 infants (82%) were born at King Edward Memorial Hospital (KEMH), a level III referral centre, and a further 4% were transferred there after birth. The proportion born at KEMH increased from 78% in P1 to 86% in P2. Survival increased from 35% to 43% overall. In those below 800 g birthweight, survival doubled from 14% to 29%. There was no change in the age at death for non-survivors. Follow-up information was known for 222 of the 229 survivors at median ages of 46 months (P1) and 43 months (P2). Disability rates in infants below 800 g birthweight remained static (P1, 26%; P2, 28%), but fell in those of 800-999 g birthweight from 24% to 13%. Overall, survival free of disability increased from 26% to 34%. CONCLUSION: Increased survival rates occurred without any increase in the rate or severity of disability in survivors.

Analgesia for the reduction of fractures in children: a comparison of nitrous oxide with intramuscular sedation.
A prospective, randomized study was undertaken to compare the effectiveness of nitrous oxide with intramuscular sedation (meperidine and promethazine) in providing analgesia and amnesia during the reduction and treatment of children's fractures in an outpatient clinic setting. Fifteen patients received a 50:50 mixture of nitrous oxide and oxygen, and 15 received intramuscular injection. The two groups were similar in regard to gender distribution, age, and fracture types. Pain response was recorded using the Children's Hospital of Eastern Ontario (Canada) Pain Scale (CHEOPS) at the time of fracture reduction and 30 min postreduction. At the first follow-up visit a questionnaire regarding the patient's memory and subjective experience of the fracture reduction was answered. Data between the two groups were compared using the Mann-Whitney test. The CHEOPS scores, and the memory and subjective experience of the fracture reduction were similar between the two groups. Time in the outpatient department averaged 83 min for the intramuscular group and 30 min for the nitrous oxide group (p < 0.01). All of the nitrous oxide patients stated they would use nitrous oxide again, whereas only eight of 15 intramuscular patients stated they would try intramuscular sedation again. Nitrous oxide is as effective as intramuscular sedation in providing analgesia and amnesia in the treatment of children's fractures while having a more rapid onset and a shorter recovery period with greater patient acceptance.

Radiosurgery for residual or recurrent nonfunctioning pituitary adenoma.
OBJECT: Nonfunctioning pituitary adenomas comprise approximately 30% of all pituitary tumors. The purpose of this retrospective study is to evaluate the efficacy and role of gamma knife radiosurgery (GKS) in the management of residual or recurrent nonfunctioning pituitary adenomas. METHODS: A review was conducted of the data obtained in 42 patients who underwent adjuvant GKS at the University of Pittsburgh between 1987 and 2001. Prior treatments included transsphenoidal resection, craniotomy and resection, or conventional radiotherapy. Endocrinological, ophthalmological, and radiological responses were evaluated. The duration of follow-up review varied from 6 to 102 months (mean 31.2 months). Fifteen patients were observed for more than 40 months. The mean radiation dose to the tumor margin was 16 Gy. Conformal radiosurgery planning was used to restrict the dose to the optic nerve and chiasm. Tumor control after GKS was achieved in 100% of patients with microadenomas and 97% of patients with macroadenomas. Gamma knife radiosurgery was equally effective in controlling adenomas with cavernous sinus invasion and suprasellar extension. No patient developed a new endocrinological deficiency following GKS. One patient's tumor enlarged with an associated decline in visual function. Another patient experienced a deterioration of visual fields despite a decrease in tumor size. CONCLUSIONS: Gamma knife radiosurgery can achieve tumor control in virtually all residual or recurrent nonfunctioning pituitary adenomas. Dose sparing facilitates tumor management even when the adenoma is close to the optic apparatus or invades the cavernous sinus.

Relative afferent pupillary defects in primary open-angle glaucoma--five years' experience.
Afferent pupillary defects may accompany asymmetric primary open-angle glaucoma, though the exact incidence has not been reported. Charts were reviewed on 89 patients attending the Glaucoma/Uveitis Clinic at the North Carolina Memorial Hospital in Chapel Hill, North Carolina over a five-year period. All patients had primary open-angle glaucoma diagnosed by: (1) increased ocular tensions (22 mmHg) in the presence of open-anterior-chamber angles and (2) optic-nerve cupping and atrophy compatible with (3) pressure-dependent, visual-field loss. No subjects with secondary glaucomas, primary-angle-closure glaucoma, or ocular hypertension are included.The presence of the relative afferent pupillary defect was noted in 21 of 89 patients (23 percent). Sixteen of 70 black patients had relative afferent pupillary defect in the more severely affected eye, while five of 19 white patients demonstrated afferent pupils. Other demographic characteristics of this population are described. Two typical primary-open-angle glaucoma patients are discussed to demonstrate comparable changes within the optic nerves and Goldmann visual fields. The presence of the relative afferent pupillary defect best correlates with asymmetric, visual-field loss in the more severely affected eye.

Effect of nappy liners on temperature stability in very preterm infants.
OBJECTIVE: To determine whether absorbent liners used in posturally supportive cloth nappies influence temperature stability in infants < 31 weeks gestation. METHODOLOGY: Randomized cross-over trial conducted at King Edward Memorial Hospital for Women, Perth, Western Australia. Twenty-three infants nursed in incubators on Infant Servo Control were randomly assigned to wear cloth postural support nappies alternately with or without absorbent liners for 24-h periods over 4 days. Measurements of skin and incubator temperatures were recorded hourly. Times of all nappy changes and infant handling procedures were also recorded. RESULTS: There was no change in any temperature measurement over time, between days, or between day/night periods. Infants nursed with the liner demonstrated a higher skin temperature (0.04 degrees C), and a lower incubator temperature (1.05 degrees C). A drop in skin temperature of 0.02 degrees C and an increase in incubator temperature of 0.28 degrees C occurred following handling of infants. There was no effect due to sex, gestational age, or actual age of the infants. CONCLUSION: Use of an absorbent liner within a cloth postural support nappy promotes better temperature regulation in infants < 31 weeks gestation, by reducing incubator temperature and increasing skin temperature.

Effect of a postural support nappy on 'flattened posture' of the lower extremeties in very preterm infants.
OBJECTIVE: To determine whether the use of a postural support nappy (PSN) would reduce the features of 'flattened posture' in the lower extremities of infants < 31 weeks gestation who are nursed prone. METHODOLOGY: Randomized, observer blind, controlled trial conducted at King Edward Memorial Hospital for Women, Perth, Western Australia. Infants were randomly assigned and stratified by gestational age to be nursed in a conventional nappy (n = 29) or a PSN (n = 31) when in the prone position. The features of 'flattened posture' were measured as angles and assessed by blinded observers prior to commencement of the intervention, 4 weeks post intervention, then bi-weekly until discharge. RESULTS: A significant reduction in the features of 'flattened posture' occurred in the PSN group after 4-6 weeks of intervention and stabilized by 8 weeks until discharge. No changes were detected in the control group. No significant difference was observed between infants < 29 weeks gestation compared to infants of 29-30 weeks gestation in either treatment group. CONCLUSIONS: Use of the PSN in infants < 31 weeks gestation who are nursed in the prone position significantly reduces the features of 'flattened posture' in the lower extremities. This is of benefit in the short term, and follow up of these infants into childhood will demonstrate whether the long-term effects of 'flattened posture' can be prevented.

Cresyl violet: a rapid, simple, easily interpretable stain for detecting Pneumocystis carinii in sputum.
Over a three-month period at the pathology laboratory of Jackson Memorial Hospital, 110 sputum samples from 62 hospitalized patients with suspected AIDS were examined for Pneumocystis carinii. Sputum specimens were either expectorated spontaneously (most patients) or expectorated after the inhalation of small amounts of nebulized normal saline. Each sputum sample was cytocentrifuged onto two slides. One slide was stained with Gomori methenamine-silver (GMS) and the other with cresyl violet (CV). Among the 62 study patients, 18 were proven to have no histologic evidence of P carinii pneumonia. Of the remaining 44 patients, P carinii organisms were found by GMS stain in 14 (32%) and by CV stain in 18 (41%). Among those with a positive CV stain, the diagnosis was made on the first sputum specimen in 14 patients and on the second specimen in the remaining four patients. CV stain is at least as sensitive as GMS in detecting P carinii cysts in the sputum of AIDS patients with P carinii pneumonia, and its diagnostic sensitivity may exceed 40% under field conditions. Further, CV stain is much simpler to prepare than GMS and much simpler to interpret than Giemsa. It could be easily adapted for general use to expedite the diagnosis and treatment of P carinii pneumonia.

Very preterm birth--a regional study. Part 2: The very preterm infant.
OBJECTIVE: To ascertain the growth characteristics, delivery room management and hospital mortality of very preterm liveborn infants (< 33 weeks of gestation) and to identify differences between infants associated with the aetiological factor related to their very preterm delivery. DESIGN: Cohort analytical study. SETTING: King Edward Memorial Hospital for Women, Western Australia. MAIN VARIABLES EXAMINED: Gestational age, birthweight, birthweight ratio, condition at birth and mortality. RESULTS: Six hundred and ninety-three liveborn very preterm infants were born to 608 mothers between 1.1.90 and 31.12.91. This was 1.37% of all liveborns in Western Australia. Three hundred and eighty-five (55.6%) were male. Growth characteristics (birthweight, birthweight ratio and proportion small for gestational age) differed between infants depending on the primary obstetric complication associated with the very preterm delivery. Overall 217 (31%) infants were small for gestational age, 34(4.9%) had a congenital anomaly, and 102 (14.7%) died. Corrected mortality, excluding major fatal congenital anomaly, was 86 (12.7%). The majority of infants died on the first day (n = 59 (57.8%)). The only factors associated with an increased or decreased mortality were decreasing gestation (adjusted odds ratio (AOR) 1.7, 95% CI 1.50-1.93), decreasing birthweight ratio (small for gestational age) (AOR 1.3, 95% CI 1.08-1.53), antepartum haemorrhage as primary complication (AOR 3.1, 95% CI 1.25-7.69) and any antenatal steroids (AOR 0.26, 95% CI 0.14-0.51). In comparison with other studies, survival in the extremely preterm group, defined as a gestational age of less than 28 weeks, is improving. CONCLUSIONS: Very preterm infants account for a large proportion of perinatal mortality. Further studies are required to explore the differences between infants on the basis of the primary obstetric complication and to ensure that increased survival is not associated with an increase in disabilities.

Very preterm birth--a regional study. Part 1: Maternal and obstetric factors.
OBJECTIVE: To ascertain the demographic, pregnancy and obstetric factors associated with the delivery of a liveborn very preterm infant ( < 33 weeks of gestation) and to investigate any differences in these factors between identifiable aetiological groups. DESIGN: Cohort analytical study. SETTING: King Edward Memorial Hospital for Women (KEMH), Western Australia. MAIN VARIABLES EXAMINED: Maternal demographic and obstetric history, primary complication associated with delivery, obstetric management and mode of delivery. RESULTS: Six hundred and eight women who were delivered of 693 liveborn very preterm infants in Western Australia between 1.1.90 and 31.12.91, representing 1.22% of all women who were delivered of a liveborn infant in those years. Singleton pregnancy occurred in 517 (85%) and 541 (89%) were delivered in KEMH. Mean maternal age was 28 years with an excess of mothers less than 20 years of age and older than 34 years compared with the statewide perinatal data. Pre-eclampsia (n = 128, 21.1%), preterm prelabour rupture of membranes (n = 148, 24.3%), idiopathic preterm labour (n = 195, 30.4%) and antepartum haemorrhage (n = 111, 18.3%) were associated with 94.1% of deliveries. These proportions varied with plurality and period of gestation. Demographic details, use of antenatal steroids, exposure to labour and caesarean section delivery differed between mothers depending on the primary complication. Overall 322 (53.0%) received antenatal steroids and 297 (48.8%) were delivered by caesarean section. Factors associated with decreased use of steroids were gestational age of less than 27 weeks (odds ratio (OR) 0.54; 95% CI 0.36-0.83), preterm prelabour rupture of the membranes (OR 0.48; 95% CI 0.29-0.78) and idiopathic preterm labour (OR 0.56; 95% CI 0.35-0.91). Factors associated with increased use of steroids were multiple pregnancy (OR 1.70; 95% CI 1.02-2.81) and pre-eclampsia (OR 1.87; 95% CI 1.09-3.19). CONCLUSIONS: These very preterm deliveries account for only a small proportion of all deliveries. There are differences in the mother's demographic history, obstetric management and delivery depending on the primary aetiological factor.

Obstetric and perinatal outcomes in pregnancies associated with illicit substance abuse.
OBJECTIVE: To determine the obstetric and perinatal outcomes of women using illicit drugs during pregnancy by substance group. METHOD: A retrospective audit of obstetric and perinatal outcomes in women who used opiates or amphetamines during their pregnancy and delivered at King Edward Memorial Hospital (KEMH), Perth, Australia between December 1997 and April 2000 was performed. Maternal, fetal and neonatal parameters were assessed. These were compared with obstetric and perinatal data recorded by the Health Department of Western Australia (HDWA) for the 25,291 deliveries of 25,677 infants in 1998. RESULTS: Between December 1997 and April 2000 91 opiate-using and 50 amphetamine-using women were identified and included in the analysis. Both groups of drug-using women were younger (opiates P = 0.001, amphetamines P = 0.001) than the general population. There was a higher incidence of aboriginality (P = 0.001) in the amphetamine group. In the opiate-using group multiparity (P = 0.0001) and anaemia (P = 0.0001) were higher. Illicit drug-using women had a higher incidence of hepatitis C (opiates P = 0.001, amphetamines P = 0.003), and a greater need for pharmacological analgesia for labour and delivery (opiates P = 0.007, amphetamines P = 0.042). Their infants were significantly more likely to deliver at less than 37 weeks' gestation (opiates P = 0.0001, amphetamines P = 0.001), to have a birthweight of less than 2.5 kg (P = 0.0001), be small for gestational age and require admission to the special care nursery (P = 0.0001). Infants born to women in the amphetamine group were more likely to have an Apgar score < 7 (P = 0.0001) recorded. Infants of women in the opiate group required more resuscitation (P = 0.05). CONCLUSION: Women who use illicit drugs are more likely to experience adverse obstetric and perinatal outcomes than women in the general population. Differences are seen depending on the type of illicit drug used. These findings need to be replicated in a larger prospective cohort to highlight management requirements of these women and their infants. Further information is required about the effects of amphetamines in pregnancy.
