Abstract
Diagnostic accuracy studies play an important role in informing clinical practice and patient management, by evaluating the ability of diagnostic testing and imaging to identify the presence or absence of a disease or condition. These studies compare the relative diagnostic strength of the test or device with a reference standard, therefore, guiding clinical decisions on the reliability of the test, the need for further tests, and whether to monitor or treat a particular condition. Inadequate and incomplete reporting of diagnostic accuracy studies can disguise methodological deficiencies and ultimately result in study bias and the inability to translate research findings into daily clinical practice. The Preferred Reporting Items for Diagnostic Accuracy Studies in Endodontics (PRIDASE) guidelines are being developed in order to improve the accuracy, transparency, completeness and reproducibility of diagnostic accuracy studies in the speciality of Endodontology. The aim of this paper is to report the process used to develop the PRIDASE guidelines based on a well-established consensus process. The project leaders (PD, VN) formed a steering committee of nine members (PD, VN, PA, AF, DR, SP, CK, MP, HD) to oversee and manage the project. The PRIDASE steering committee will develop the initial draft of the PRIDASE guidelines by adapting and modifying the Standards for Reporting of Diagnostic Accuracy Studies (STARD) 2015 guidelines, adding new items related specifically to the nature of Endodontics and incorporate the Clinical and Laboratory Images in Publication (CLIP) principles. The initial guidelines will consist of a series of domains and individual items and will be validated by the members of a PRIDASE Delphi Group (PDG) consisting of a minimum of 30 individuals who will evaluate independently the individual items based on two parameters: 'clarity' using a dichotomous scoring (yes/no) and 'suitability' for inclusion using a 9-point Likert Scale. The scores awarded by each member and any suggestions for improvement will be shared with the PDG to inform an iterative process that will result in a series of items that are clear and suitable for inclusion in the new PRIDASE guidelines. Once the PDG has completed its work, the steering committee will create a PRIDASE Meeting Group (PMG) of 20 individuals from around the world. Members of the PDG will be eligible to be the part of PMG. The draft guidelines and flowchart approved by the PDG will then be presented for further validation and agreement by the PMG. As a result of these discussions, the PRIDASE guidelines will be finalized and then disseminated to relevant stakeholders through publications and via the Preferred Reporting Items for study Designs in Endodontology (PRIDE) website (http://pride-endodonticguidelines.org). Periodic updates to the PRIDASE guidelines will be made based on feedback from stakeholders and end-users.

Abstract
OBJECTIVES Assess unforeseen consequences of Telehealth and suggest solutions Methods: An outline was created collecting all possible ill effects classified into Clinical considerations, Administrative concerns including interpersonal relations, Technical issues, Legal / Ethical concerns and Miscellaneous. Each topic was assigned to a particular WG member to lead, gather opinion and review existing literature. RESULTS AND CONCLUSION A wide array of problems have been described. Except for technical issues, literature on this topic is scant, so this article is based more on personal experience and data collected from surveys. Much can be done to prevent such problems, such as a need for standardization with related clinical studies for devices as well as processes used for telehealth is underlined, besides evaluation of outcomes of projects undertaken.

Abstract
AIM To investigate the distribution of bacteria within the dentine tubular network in a two-chamber model in order to determine a possible route of penetration. METHODOLOGY Root canals of teeth in the experimental group (n = 16) were instrumented and root filled using AH26 and gutta-percha. Canals in the teeth serving as positive (n = 1) and negative (n = 1) controls were instrumented, but not root filled. A two-chamber model was fabricated for each root - upper chambers were inoculated weekly with Streptococcus gordonii in brain-heart infusion broth over 90 days. Turbidity of the lower chamber was checked daily. Samples that showed turbidity during the experimental period and samples that showed no signs of turbidity at 90 days were fractured and prepared for SEM examination. SEM examination for the presence of bacteria within the dentinal tubules was performed in the cervical, middle and apical root thirds. In each root third, the depth of bacterial penetration was recorded as inner, middle or outer dentine. RESULTS Bacteria were most commonly detected in the cervical third (14 of 30 areas). Irrespective of the root third examined, bacteria were most commonly detected in the inner dentine (i.e. adjacent to the root canal). Only two samples demonstrated bacterial penetration in the outer dentine. CONCLUSION The dentine tubular network provides a potential pathway for bacteria to penetrate tooth roots in a two-chamber model.

Abstract
OBJECTIVE Provide evidence-based advise to "Program of All-inclusive Care for the Elderly" (PACE) decision makers considering implementing an electronic health record (EHR) system, drawing on the results of a mixed methods study to examine: (1) the diffusion of an EHR among clinicians documenting direct patient care in a PACE day care site, (2) the impact of the use of the EHR on the satisfaction levels of clinicians, and (3) the impact of the use of the EHR on patient functional outcomes. METHODS Embedded mixed methods design with a post-test design quantitative experiment and concurrent qualitative component. Quantitative methods included: (1) the EHR audit log used to determine the frequency and timing during the week of clinicians' usage of the system; (2) a 22-item clinician satisfaction survey; and (3) a 16-item patient functional outcome questionnaire related to locomotion, mobility, personal hygiene, dressing, feeding as well the use of adaptive devices. Qualitative methods included observations and open-ended, semi-structured follow-up interviews. Qualitative data was merged with the quantitative data by comparing the findings along themes. The setting was a PACE utilizing an EHR in Philadelphia: PACE manages the care of nursing-home eligible members to enable them to avoid nursing home admission and reside in their homes. Participants were 39 clinicians on the multi-disciplinary teams caring for the elders and 338 PACE members. RESULTS Clinicians did not use the system as intended, which may help to explain why the benefits related to clinical processes and patient outcomes as expected for an EHR were not reflected in the results. Clinicians were satisfied with the EHR, although there was a non-significant decline between 11 and 17 months post implementation of the EHR. There was no significant difference in patient functional outcome the two time periods. However, the sample size of 48 was too small to allow any conclusive statements to be made. Interpretation of findings underscores the importance of the interaction of workflow and EHR functionality and usability to impact clinician satisfaction, efficiency, and clinician use of the EHR. CONCLUSION This research provides insights into EHR use in the care of the older people in community-based health care settings. This study assessed the adoption of an EHR outside the acute hospital setting and in the community setting to provide evidence-based recommendations to PACE decision makers considering implementing an EHR.

Abstract
BACKGROUND While the ingestion of small amounts of an offending food can elicit adverse reactions in individuals with IgE-mediated food allergies, little information is known regarding these threshold doses for specific allergenic foods. While low-dose challenge trials have been conducted on an appreciable number of allergic individuals, a variety of different clinical protocols were used making the estimation of the threshold dose very difficult. OBJECTIVE A roundtable conference was convened to develop a consensus clinical protocol for low-dose challenge trials for the estimation of threshold doses for specific allergenic foods. METHODS In May 2002, 20 clinical allergists and other interested parties were invited to participate in a roundtable conference to develop consensus of the key elements of a clinical protocol for low-dose challenge trials. RESULTS A consensus protocol was developed. Patients with convincing histories of food allergies and supporting diagnostic evidence including past challenge trials or high CAP-RAST scores can be enrolled in low-dose challenge trials. Care must be taken with younger patients to assure that they have not outgrown their food allergy. An approach was developed for the medication status of patients entering such trials. Challenge materials must be standardized, for example, partially defatted peanut flour composed of equal amounts of the three major varieties of peanuts (Florunner, Virginia, Spanish). Challenge materials must be appropriately blinded with sensory evaluation used to confirm the adequacy of blinding. A double-blind, placebo-controlled design should be used for low-dose challenge trials. Low-dose challenge trials would begin at doses of 10 microg of the allergenic food and would continue with doses of 100 microg and 1 mg followed by specific higher doses up to 100 mg depending upon the expert judgement of the physician; even higher doses might be applied to assure that the patient is indeed reactive to the particular food. A 30-min time interval would be used between doses, and reactive doses would be expressed as both discrete and cumulative doses. The goal of each challenge would be to develop objective symptoms; trials should not be discontinued on the basis of subjective symptoms only. Statistically, a minimum of 29 patients would be enrolled in low-dose challenge trials for each allergenic food because 0 reactors out of 29 patients at a particular dose allow the conclusion that there is 95% certainty that 90% of allergic individuals will not react to that dose. CONCLUSION A consensus protocol was developed. Using this protocol, it will be possible to estimate threshold doses for allergenic foods, the lowest amount that elicits mild, objective symptoms in highly sensitive individuals.

Abstract
We report the neuropsychological profile associated with variant Creutzfeldt-Jakob disease (vCJD). A retrospective study was carried out of data from neuropsychological reports prepared on 24 patients with vCJD. While there was some variability in neuropsychological profiles, the overall pattern was one of a combined cortical and subcortical dementia, with impaired performance being particularly prominent on tests of memory, executive function, speed of attention, and visuoperceptual reasoning. Across 16 cases where Wechsler Adult Intelligence Scale-Revised intelligence quotient (IQ) scores were available, this profile was in part reflected by an invariably low performance IQ (<90 in all patients). All patients who received tests of verbal fluency, digit-symbol substitution and faces recognition memory showed deficits on these tests. Basic vocabulary, digit span and verbal reasoning skills were relatively preserved in most patients. In four cases who underwent more detailed cognitive testing, additional observations were made of relatively intact long-term autobiographical memory and faces perception. Cognitive impairment may represent one of the earliest features of vCJD and it is possible that, at least in some cases, neuropsychological deficits precede the onset of psychiatric or neurological symptoms. Our findings may help in the early detection and management of patients with vCJD.

Abstract
Vaccination of health care workers against influenza is considered to be important as a means of protecting patients from nosocomial infection. Vaccine uptake rates have been reported to be no more than 40% and often between 20 and 30%. An evaluation of the performance of UK National Health Service trusts, following a governmental directive to implement vaccination during the winter of 2000-2001, has shown a poor uptake of vaccine. Reasons for accepting or declining vaccine are discussed. There is a need for global leadership on this issue to promote the value of vaccination and to change the behaviour of health care workers.

Abstract
We report the first neuropsychological-neuropathological case study of a patient with variant Creutzfeldt-Jakob disease (vCJD) who was seen at the early stages of the disease, and whose cognitive functioning was monitored in the following months until his death. At presentation, his neuropsychological profile included impaired ability to retain new episodic information, deficits on tests of retrieval from semantic memory, and impairments on tests of memory for public knowledge, such as famous personalities. Tests of executive function were also performed poorly. Picture recognition memory and autobiographical memory were relatively spared, as was performance on tests of face perception and complex copying ability. Neuropsychological testing may be useful in monitoring the progression of vCJD, and we provide evidence to show a steady rate of decline in perceptual and naming tasks over a 4-month period. Post-mortem findings showed neuronal loss in the caudate, putamen, dorsal thalamus, cerebellum and occipital cortex. Spongiform changes were found throughout the brain, including the entorhinal cortex and anterior thalamus. Prion protein accumulation was noted in the hippocampus. We hypothesize that primary subcortical damage to structures in the thalamus and neostriatum, together with secondary frontal lobe dysfunction, combine to yield the pattern of neuropsychological impairment and neuropsychological sparing that was found.

Abstract
The vancomycin pharmacokinetic profile was characterized in six pediatric patients and the potential of nonlinear mixed effects modeling and Bayesian forecasting for vancomycin monitoring was explored using NONMEM V (1.1). Based on steady state serial vancomycin concentrations, the estimates of mean t1/2, Vd, and Cl derived by the Sawchuk and Zaske method (1) were 3.52 hours, 0.57 L/kg, and 0.12 L/h per kg, respectively. NONMEM analysis demonstrated that a weight-adjusted two-compartment model described individual patients' data better than a comparable one-compartment model. The two-compartment estimates of mean t1/2alpha, t1/2beta, Vss, and Cl were 0.80 hour, 5.63 hours, 0.63 L/kg, and 0.11 L/h per kg, respectively. The relatively long mean t1/2alpha suggests that peak vancomycin concentrations measured earlier than 4 hours postdose do not reflect postdistributional serum concentrations. NONMEM population modeling revealed that a weight-adjusted two-compartment model provided a better fit than a comparable one-compartment model. The resulting population parameters and variances were fixed in NONMEM to obtain Bayesian predictions of individual vancomycin serum concentrations. Bayesian estimation with either a single midinterval or trough sample has the potential to provide accurate and precise predictions of vancomycin concentrations. This should be evaluated using a vancomycin population pharmacokinetic model based on a larger sample of pediatric patients.

Abstract
Dental patients are often aware that radiation has the potential to harm them but they do not usually understand how or why and what potential harmful effects may arise from dental radiographs. The potential for undesirable effects must be balanced against the benefits obtained from radiographs. Dentists should address the concerns of patients who question the need for radiographs and allow them to make an informed decision. Data are available that relate radiation exposure levels from medical and dental radiographs to normal background exposure levels and allow comparisons with everyday risks in life. Recognized radiation authorities publish guidelines to help dentists with their use of radiographs, although, due to the time lag associated with testing and the publication of results, some of the published data may not always be entirely relevant to currently used X-ray machines and techniques. Dentists also have professional obligations not only to limit the use of radiographs to potentially beneficial situations but also to take good quality diagnostic radiographs, to limit the doses used, to use good radiation safety measures and to use modern equipment to achieve the best possible films. Radiographs must then be properly developed and viewed under appropriate conditions to gain the maximum possible diagnostic information from each exposure.

Abstract
Endodontic-periodontal lesions can provide many challenges to clinicians. Although there may be difficulties in establishing a correct diagnosis, this is the most important phase of their management as the diagnosis will determine the type and sequence of treatment required. In general, if the root canal system is infected, endodontic treatment should be commenced prior to any periodontal therapy in order to remove the intra-canal infection before any cementum is removed. This avoids several complications and provides a favourable situation for tissue repair. The endodontic treatment can be completed before periodontal treatment is provided except where there is a "combined endodontic-periodontal lesion with communication"--in these cases, the root canals should be medicated until the periodontal treatment has been completed and the overall prognosis has been reassessed as being favourable. The use of non-toxic intra-canal therapeutic medicaments is essential to destroy bacteria and to encourage tissue healing.

Abstract
Several clinical and methodological caveats are outlined as they pertain to retrograde amnesia research, and data relevant to these caveats are presented. Three caveats in particular are noted in relation to recently published cases of marked retrograde amnesia; (i) temporal lobe epilepsy may influence memory for news events; (ii) there may be additional, unsuspected pathology in cases of amnesia, such as those with cerebral hypoxia; (iii) degree of media exposure is closely related to performance on the types of news events memory tests that are commonly used in retrograde amnesia research.

Abstract
Internationally acceptable norms need to incorporate sound science and consistent risk management principles in an open and transparent manner, as set out in the Agreement on the Application of Sanitary and Phytosanitary Measures (the SPS Agreement). The process of risk analysis provides a procedure to reach these goals. The interaction between risk assessors and risk managers is considered vital to this procedure. This paper reports the outcome of a meeting of risk assessors and risk managers on specific aspects of risk analysis and its application to international standard setting for food additives and contaminants. Case studies on aflatoxins and aspartame were used to identify the key steps of the interaction process which ensure scientific justification for risk management decisions. A series of recommendations were proposed in order to enhance the scientific transparency in these critical phases of the standard setting procedure.

Abstract
There are few clues as to the processes that underlie recovery of function from human amnesia. Evidence is offered from the perspective of a study of recovery of function during an episode of transient global amnesia (TGA) that occurred as a complication of a cerebral angiographic procedure being carried out in a neurosciences centre, and where there was therefore a unique opportunity to examine acute changes in memory function. This allowed us to conduct the first quantitative study where shrinkage of anterograde and retrograde memory loss was plotted at four separate intervals throughout the acute recovery process, and also 24 hr later. Recovery of retrograde amnesia preceded recovery from anterograde amnesia. Resolution of a naming deficit more closely paralleled recovery from retrograde amnesia rather than anterograde amnesia. Within retrograde amnesia for public events, there was a temporal gradient of memory loss, with more recent events affected to a greater degree than earlier events. Within anterograde amnesia, picture recognition memory preceded recovery of story recall memory. On the basis of these findings, and related observations in the published literature, it is proposed that recovery from some types of human amnesia, such as that associated with TGA, follows a 'lateral-to-medial' rule--lateral inferotemporal areas that play a major role in retrograde amnesia recover first from hypometabolism related to the TGA attack, followed by 'interface' areas such as the rhinal and parahippocampal cortices that are considered to have a role in both anterograde and retrograde memory functioning, with the last areas to recover physiological integrity being discrete limbic-diencephalic structures such as the hippocampus.

Abstract
The temporal fractionation of long-term retention remains a relatively uncharted area in human memory research, and in particular there is little in the way of neuropsychological data that address this issue. We describe a patient with temporal lobe epilepsy who complained of amnesia for important events that had occurred in the previous 3-24 months, but who reported that her short-term and medium-term memory were normal. She displayed normal performance on traditional tests of short-term and long-term retention, performing at a very similar level to that of age- and sex-matched healthy control subjects on immediate and half-hour delayed recall measures. Forty days later, however, she showed a dense amnesia for recall of such information, whereas control subjects could readily recall much of the original stimuli. She also showed evidence of memory loss for news events that had occurred over the previous few years. MRI scanning and EEG brain mapping indicated left temporal lobe pathology, with a possible epileptogenic focus in the left anterior hippocampus. These data provide empirical evidence for the existence of a distinct very long-term consolidation process in human episodic memory and point to its neural correlates in the temporal lobe. Transfer of information into a permanent long-term memory store may entail multiple-stage consolidation processes rather than a single-stage, unitary consolidation process.

Abstract
Managed care has brought about changes in the way surgical departments function. Minimally invasive surgeries are common, but costly for the surgical department. The use of reusable or resposable instruments can help keep costs down.

Abstract
This paper addresses the question as to whether long-term perceptual priming can occur during transient global amnesia. A patient who displayed the classical features of transient global amnesia was assessed during the episode and again 7 days later. During the episode, she was administered a task that required the perceptual identification of fragmented pictures over a number of learning trials. Seven days later, after recovery from the episode, she was required to identify the same fragmented pictures together with a new set of pictures that she had never seen before. She was significantly better at identifying the old pictures than the new pictures, in spite of having amnesia for the period of the attack. Matched control subjects who had never seen either set of pictures before, were also tested and performed at a similar level on the old and the new pictures. Our findings extend the clinical domain of implicit memory phenomena and parallel similar observations in chronic amnesia (Cave & Squire, 1992). We provide the first demonstration of a residual capacity for long-term perceptual priming during an acute episode of apparent total loss of memory.

Abstract
This study aimed to clarify the pre-operative-personality-post-operative-recovery association by considering anaesthetic variables. Additionally, the work investigated the relationships between psychological and cardiovascular functioning and anaesthetic induction difficulties and operative problems. Two minor gynaecological procedures were evaluated (dilatation and curettage, laparoscopy) which differ greatly in anaesthetic and operative techniques. Psychological factors predicted cardiovascular responding immediately prior to the induction of anaesthesia, and combinations of cardiovascular and psychological variables were associated with anaesthetic induction, operative and post-operative problems. Health locus of control and worry concerning the various stages of the operation emerged as the most consistent psychological predictors of peri-operative outcome in both procedures.

Abstract
Ingestion of placenta or amniotic fluid by rats has been shown to enhance ongoing opioid-mediated antinociception, but does not, by itself, produce antinociception. This enhancement is produced by an active substance(s) in placenta and amniotic fluid that we have termed POEF for placental opioid-enhancing factor. Previous research has shown that enhancement requires mediation by the gastrointestinal system: gastric vagotomy blocks enhancement produced by ingested placenta; amniotic fluid injected SC or IP does not produce enhancement. The present study was designed to distinguish between two possible explanations for the blockade of the POEF effect produced by gastric vagotomy: that afferent information arising in vagal gastric receptors conveys the critical information to the CNS, or that disruption of vagal efferent action on digestion blocks the manufacture or activation of the POEF molecule in the gut. Famotidine is an H2-histamine receptor antagonist that reduces gastric acid and pepsin secretion to an extent at least as great as gastric vagotomy. Rats treated with either famotidine or a vehicle were fed placenta or a control substance, then stimulated with vaginal/cervical probing to produce antinociception that is partly opioid mediated. Famotidine did not block POEF enhancement of vaginal/cervical stimulation-induced analgesia in a tail flick latency test. These results suggest that enhancement by POEF does not require normal digestive processes or other processes inhibited by famotidine.

Abstract
The design of Computerized Patient Record databases needs to be different depending on whether the focus of the database is transaction processing or analytical processing. Transaction processing includes the operational use of databases for single patient update during clinical encounters. Analytical processing includes cross-patient querying for research or clinical management. These different design needs are defined. A case study is presented for the methodology that transforms transaction databases to analytical ones. The resulting analytical design is argued to be successfully evaluated according to specific criteria of useability and maintainability. This methodology is easily replicated in any relational database environment.

Abstract
An automated telephone screening system was implemented at the Baltimore VA Hospital on a Local Area Network (LAN) to evaluate older adults for the GRECC research program. Using the system for decision support, a registered nurse (RN) placed 117 phone calls to older adults in the Baltimore community over a 3 month period. The modular design of the system allowed tracking of inclusion and exclusion criteria which was shared by clinicians and researchers. The design goal of the telephone screening system was to reduce time and personnel costs and increase the effectiveness of screening for recruitment for a major research project. Effectiveness is defined as avoiding under--or over--screening. Using the telephone system, it is estimated the research team saved over $6,000.00 in unnecessary medical evaluation in a 3 months period. As the system develops, the process by which older adults are assessed for research programs in the Geriatrics Service at the Baltimore VAMC will provide additional cost efficiencies.

Abstract
A substance in amniotic fluid and placenta (POEF for Placental Opioid-Enhancing Factor) has been shown to enhance opiate- or opioid-mediated analgesia in rats. Recent studies have only touched on the generalizability of the phenomenon. The present studies further tested the generalizability of the POEF effect: they examined sex specificity of the mechanism; whether POEF activity exists in afterbirth material of species other than the rat; whether POEF activity exists in tissue other than afterbirth material; whether POEF activity could be demonstrated after injection rather than ingestion of afterbirth material; and whether POEF enhances all opioid-mediated phenomena. We found that (a) POEF is effective in male rats as well as in female rats; (b) POEF activity exists in human and dolphin afterbirth material; (c) ingestion of pregnant-rat liver does not produce enhancement of opioid-mediated analgesia; (d) POEF does not seem to be effective when amniotic fluid is injected either IP or SC; and (e) POEF does not modify morphine-induced hyperthermia.

Abstract
A substance in amniotic fluid (AF) and placenta has been shown to enhance analgesia produced by morphine, late pregnancy, footshock, and vaginal/cervical stimulation (VS). When morphine-induced analgesia was assessed previously, the degree of enhancement by ingestion of AF or placenta was found to be a function of the amount of analgesia being generated. We have extended these results to include the analgesia produced by VS. Analgesia induced by 75, 125, 175, or 225 g of vaginal/cervical pressure was measured in rats pretreated with 0.25 ml (by orogastric infusion) of either AF or saline. AF infusion enhanced the analgesia produced by 125 g VS, but did not affect the analgesia produced by 75, 175, or 225 g VS. Unexpectedly, we also found that infusion of AF shortly before the application of VS prevents VS-induced pseudopregnancy (PsP). Whereas the incidence of PsP following 75, 125, or 175 g VS was less than 19% and not statistically different for AF and saline pretreatments, the incidence of PsP after 225 g VS was 44% in saline-pretreated rats, but only 10% in AF-pretreated rats. Protection from the induction of pseudopregnancy, which could be caused by mechanical stimulation of the cervical area during delivery, may be an additional benefit of parturitional ingestion of placenta and amniotic fluid (placentophagia).

Abstract
Forty-five primary human lung carcinomas were evaluated for the loss of heterozygosity for genes on the short end of chromosome 11. Of 40 evaluable heterozygous cases, loss of the 11p genes c-H-ras and insulin was documented in nine cases (22%). The clinical parameters investigated for each patient included the disease stage at presentation, the presence of metastatic disease in either bronchial or mediastinal lymph nodes, and the presence of positive parietal pleural margins in the surgically resected specimen. There were no differences found with respect to these indicators when patients exhibiting the loss of heterozygosity were compared with those who did not have such genetic loss. In addition, when the clinical courses of the two patient groups were compared, there was no difference in survival. We conclude that the loss of heterozygosity for c-H-ras and insulin on 11p is a common finding in primary non-small cell human lung carcinomas but does not confer a more aggressive phenotype on these tumors. Although this genetic lesion may be important in the initial transformation of the cells to carcinoma, the available data for lung carcinoma are insufficient to prove causality.

Abstract
A retrospective survey of 1,661 patients seen over a 10-year period at a pain clinic yielded 55 patients with intractable neck pain as the presenting complaint. In 89% there was an industrial or motor vehicle accident as the precipitating event, 78% were involved in legal proceedings relating to the accident, and in 87% the pain radiated to neighboring structures. Diagnostically, 36% had no physical signs, and cervical radiographs were normal for 46%. There was a high incidence of previous psychiatric treatment (53%) and major intrafamily problems (60%). Treatment mainly by psychotherapy or tricyclic antidepressants resulted in some benefit for 56% of patients. Legal compensation and change in occupation were not major factors influencing the outcome of treatment.

Abstract
Amniotic fluid and placenta contain a substance (POEF, for Placental Opioid-Enhancing Factor) that, when ingested, enhances opioid-mediated analgesia in nonpregnant rats; ingestion of the substance by rats not experiencing opioid-mediated analgesia, however, does not produce analgesia. It is highly likely that periparturitional analgesia-enhancement is a significant benefit of ingestion of the afterbirth (placentophagia) during delivery. Here we report that prepartum ingestion of amniotic fluid (via orogastric infusion) does indeed enhance the endogenous-opioid-mediated analgesia evident at the end of pregnancy and during delivery; that the degree of enhancement is greater with 0.75 ml than with 0.25 ml; and that the prepartum enhancement of analgesia can be blocked with the opioid antagonist naloxone.

Abstract
To assess the severity of distress and of somatization in hypochondriasis, the authors administered several validated self-rating scales of depression, anxiety, somatic symptoms, and anger/hostility to 21 psychiatric outpatients with the DSM-III diagnosis of hypochondriasis and to matched groups of other nonpsychotic psychiatric patients, family practice patients, and employees. Anxiety and somatic symptoms were highest in hypochondriacal patients; depression and anger/hostility did not differ from those of other psychiatric patients but were higher than in the other groups. The findings do not support the theory that hypochondriasis is a defense against anxiety or that it is a masked depression or depressive equivalent. The findings are consistent with the view that the interaction of severe anxiety and severe somatic symptoms is a common feature of the psychopathology of hypochondriasis.

Abstract
Ingestion of amniotic fluid and placenta by rats has been shown to enhance opioid-mediated analgesia. The present studies were designed to examine the effect of several doses and volumes of placenta and amniotic fluid on tail-flick latency in rats treated with 3 mg/kg morphine. The optimal dose of amniotic fluid was found to be 0.25 ml, although 0.50 and 1.0 ml also produced significant enhancement. Doses of 0.125 and 2 ml of amniotic fluid were ineffective, as was a dose of 0.25 ml diluted to 2 ml with saline. The optimal dose of placenta was found to be 1 placenta, although the resulting enhancement was not significantly greater than that produced by 025, 0.50, 2.0 or 4.0 placentas. Doses smaller than 0.25 placenta or larger than 4.0 placentas were ineffective. The most effective doses of amniotic fluid and placenta correspond to the amounts delivered with each pup during parturition.

Abstract
Infrapatellar Contracture Syndrome (IPCS) is an infrequently recognized cause of posttraumatic knee morbidity. Unique to this group of patients is the combination of restricted knee extension and flexion associated with patella entrapment. IPCS can occur primarily as an exaggerated pathologic fibrous hyperplasia of the anterior soft tissues of the knee beyond that associated with normal healing. It can also occur secondarily to prolonged immobility and lack of extension associated with knee surgery, particularly intraarticular ACL reconstruction. IPCS follows a predictable natural history which is divided into three stages. Symptoms, diagnostic findings, and recommended treatment are determined by the stage at presentation. Once beyond its early presentation, IPCS is best treated by an anterior intraarticular and extraarticular capsular debridement and release, followed by extensive rehabilitation. The authors review 28 consecutive cases of IPCS. At followup 3 months to 4 years postoperation, the patients had averaged 2.3 additional surgical procedures following their index procedure or injury. The average increase in extension at followup was 12 degrees with the average increase flexion 35 degrees. Eighty percent of patients demonstrated signs and symptoms consistent with patellofemoral arthrosis; 16% of the patients demonstrated patella infera. The authors conclude that prevention or early detection and aggressive treatment are the only ways of avoiding complication in these problem cases.

Abstract
In order to explore fears, beliefs, and attitudes of patients with DSM-III hypochondriasis, the authors administered the self-rated Illness Attitude Scales to 21 patients with hypochondriasis, matched family practice patients, nonpatient employees, and nonhypochondriacal psychiatric patients. Hypochondriacal patients reported more fears of and false beliefs about disease; they attended more to bodily sensations, had more fears about death, and distrusted physicians' judgments more, yet sought more medical care than other subjects. They did not take better precautions about their health. The self-report of overt attitudes suggests a characteristic syndrome, consistent with the DSM-III description of hypochondriasis. Two of the subscales of the Illness Attitude Scales yielded characteristic responses in hypochondriasis.

Abstract
Placenta ingestion has recently been shown to enhance opiate-mediated analgesia produced by morphine injection, footshock, or vaginal/cervical stimulation. The enhancement of the effect of endogenous opiates (especially analgesia) may be one of the principal benefits to mammalian mothers of placentophagia at delivery. During labor and delivery, however, mothers also ingest amniotic fluid (AF) which, unlike placenta, becomes available during, or even before expulsion of the infant. The present experiments were undertaken to determine whether AF ingestion, too, enhances analgesia; if so, whether the effect requires ingestion of, or merely exposure to, AF; whether the effect can be produced by AF delivered directly to the stomach by tube; and whether the enhancement, if it exists, can be blocked by administering an opiate antagonist. Nulliparous Long-Evans rats were tested for analgesia using tail-flick latency. We found that rats that ingested AF after receiving a morphine injection showed significantly more analgesia than did rats that ingested a control substance; AF ingestion, alone, did not produce analgesia; ingestion of AF, rather than just smelling and seeing it, was necessary to produce analgesia enhancement; AF produced enhancement when oropharyngeal factors were eliminated by delivering it through an orogastric tube; and treatment of the rats with naltrexone blocked the enhancement of morphine-induced analgesia that results from AF ingestion.

Abstract
Beliefs and attitudes which can be responsible for hypochondriacal behavior were explored by administering the Illness Attitude Scales and two distress scales to patients attending a family practice clinic, nonpsychotic psychiatric outpatients and a random group of employees. Family practice patients were more distressed, had more hypochondriacal concerns and had more bodily preoccupations than employees and took more precautions about their health. Psychiatric patients were more distressed and had more fears about illness and death than family practice patients, yet took fewer precautions about their health. The findings appear to have implications for treatment.
