Provision of forensic healthcare services may affect patient safety and criminal justice outcomes. We reviewed models of delivery for services in police custody in terms of cost, types of healthcare professionals and their minimum required experience, training and qualification. Relevant information was requested under the Freedom of Information Act from all police services in England, Wales and Northern Ireland. Additional information was sought from the London Ambulance Service and the Metropolitan Police Service. A third of respondent police services refused to provide the requested information and only a small minority answered the questions in their entirety. Many police services cited excessive cost and commercial interests as reasons for not providing the information. A marked variation in models of forensic healthcare provision across police services which responded was identified. London Ambulance Service call-outs to Metropolitan Police Service custody suites for those arrested varied from 0% to 3.8%. There is substantial inconsistency and variability of information on forensic healthcare services in police custody. A standardised national dataset of all aspects of police custodial healthcare (irrespective of by whom such services are provided) should be established. We advise that the Association of Police & Crime Commissioners, College of Policing the National Police Chiefs' Council and NHS England Health and Justice engage on these matters and work with the Faculty of Forensic & Legal Medicine, the United Kingdom Association of Forensic Nurses and Paramedics, and the College of Paramedics to restart the transfer of all police custodial healthcare services to the National Health Service.

Awareness of the nature and frequency of complaints against health care professionals working in police custodial health care services could provide opportunities to improve patient safety. To explore this freedom of information requests were sent to police services in England, Wales and Northern Ireland, to professional regulatory bodies and to the Independent Office for Police Conduct. Eighty-seven percent of police services responded but only a minority provided complete responses, with data not being held, or not being held in an easily retrievable format, being provided as reasons. The nature and frequency of complaints were similar to a previous 2017 study, suggesting a failure to learn lessons from the investigation of complaints and implement change in clinical practice. No evidence of an accessible complaints handling and recording procedure was provided across the police services surveyed. Regulatory bodies provided some information on the nature of complaints made against doctors and nurses working in police custodial settings, but that for paramedics was unable to do so. It is recommended that the communication loop between police services, those bodies providing health care and forensic medical services and regulatory bodies needs to be closed. A common reporting system or the application of established complaints handling procedures and reporting structures, which could be achieved by transferring these services to the National Health Service, may enhance patient safety in police custody.

Introduction: Most findings of forensic pathology examinations are presented as written reports. There are currently no internationally accepted recommendations for writing forensic pathology reports. Existing recommendations are also varied and reflect the differences in the scope and role of forensic medical services and local settings in which they are to be implemented. The legal fact-finder thus faces wide variation in the quality of forensic pathology reports, which poses a threat to the reliability of legal decision-making. To address this issue, the development of the "PERFORM-P (Principles of Evidence-based Reporting in FORensic Medicine-Pathology version)" was undertaken. The goal of the PERFORM-P is to provide common practice recommendations adaptable to local requirements to promote evidence-based practice (EBP) in forensic pathology., Methods: An international consensus study was conducted in three phases by (1) developing a long-list of items to be considered in the reporting recommendations, (2) conducting a Delphi process (an iterative survey method to transform individual opinions into group consensus) with international forensic pathologists, and (3) designing the PERFORM-P prototype and its accompanying manual., Results: With assistance from 106 forensic pathologists/forensic medical practitioners from 41 countries, the PERFORM-P was developed. The PERFORM-P consists of a list of 61 items to be included in a forensic pathology report, which is accompanied by its Explanation and Elaboration (E&E) document., Discussion: To prepare forensic pathology (postmortem) reports that incorporate principles of evidence-based practice, internationally accepted recommendations might be helpful. The PERFORM-P identifies recommendations for necessary elements to include in a forensic pathology report. PERFORM-P can be applied to a wide range of matters requiring forensic pathological analysis, acceptable to forensic pathologists from a representative selection of jurisdictions and medico-legal systems., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 The Authors.

Spit guards, also known as spit hoods or spit masks (and occasionally bite guards) are devices intended to cover the mouth, face and sometimes the head of a restrained person in order to prevent them spitting at, or biting others. There is substantial controversy about their use with views often polarised between civil and human rights campaigners who express concerns about their utility, their safety, and their possible encroachment on human rights, and in contrast by (predominantly) law enforcement campaigners highlighting concerns about the possible risks of transmission of infection and subsequent need for prophylaxis by law enforcement professionals exposed to biological fluids. This study explored the extent to which police services deploy spit guards and the rationale underpinning their use. A mixed qualitative and quantitative approach was used to analyse data obtained from police services under the Freedom of Information Act. This study shows there is paucity of information readily available from police services in respect of quantifying the numbers of police officers who have contracted infectious disease as a result of spitting and/or bites, despite the fact that risk of infection and the need for subsequent prophylaxis is a driver of police services adopting the use of spit guard devices. Consideration must be afforded to the possibility that the use of spit guards represents a form of mechanical restraint rather than a means to prevent transmission of infection, especially given the paucity of information available from police services in respect of officers who have contracted infectious disease as a result of spiting and/or bites., (Copyright © 2019 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Article 25 of the Charter of Fundamental Rights of the European Union (adopted in Nice on 7 December 2000) recognizes and respects the rights of older people to lead a life of dignity and independence and to participate in social and cultural life. It also highlights the importance of prevention and recognition of elder abuse, especially since exposure to violence is likely as the population ages, either in familial or in institutional settings. Elder abuse has some issues in common with child abuse but in spite of this fact currently is less recognized. Health professionals have a major role to play in early detection and management of cases of elder abuse. This protocol summarizes some key concepts and approaches to assist in the timely detection and investigation of elder abuse cases by healthcare professionals and forensic practitioners.

Complaints management is an integral component of good clinical governance and an essential contributor to patient safety. Little is known about complaints against health-care professionals (HCPs) in police custodial settings and sexual assault referral centres. This study explored the frequency with which complaints are made against such HCPs working in England, Wales and Northern Ireland. It explored the nature of those complaints and the procedures by which they are investigated. Relevant information was requested from all police services in England, Wales and Northern Ireland; professional regulatory bodies; and the Independent Police Complaints Commission under the Freedom of Information Act (FOIA). Eighty-nine per cent of police services responded to the FOIA request. However, only a minority of these provided detailed information. Many police services cited the provision of health-care services by external providers as the reason for not holding information upon complaints. There was no evidence of any upward trend in the numbers of complaints over the study period. Delayed response to a request for attendance, incivility, medication issues and issues regarding the quality of reports and evidence were amongst the most common types of complaints described. A small number of responders provided copies of the disciplinary procedures used to manage complaints against HCPs. Significant heterogeneity exists in respect of complaints handling procedures across custodial and forensic medical/health-care services and sexual offence examiner services. An opportunity to identify learning for improvement is being missed as a result of the absence of standardised complaints handling procedures.

The aim of this study was to determine the incidence of, and any changes in, usage patterns of the less-lethal forms of Use of Force (UoF) modalities--incapacitant spray, impact rounds, and Taser(R)--between 2007 and 2011 by English and Welsh police services. Additional information regarding the deployment and discharge of firearms was also sought. Two thousand Freedom of Information Act applications were made to 50 police services in England and Wales and related jurisdictions requesting the provision of: (a) the total number of deployments of incapacitant sprays, Taser(R), impact (baton) rounds, and armed response units (ARU); (b) the numbers and types of any resulting medical complications; and (c) the details of any local policies requiring assessment by a healthcare professional following a deployment. Responses were received from 47 police services, with only 10 of these supplying complete data. The remainder supplied incomplete data or refused to supply any data under s12 of the Freedom of Information Act (time and cost restrictions). From 2007 to 2011, the use of incapacitant sprays, Taser, and firearms have increased (incapacitant sprays deployed: 3496, 3976, 6911, 6679, 6853; Taser deployed: 499, 2659, 4560, 6943, 7203; Taser discharged: 15, 85, 161, 338, 461; firearms: 0, 7, 4, 19, 32). Baton rounds and ARU use showed greater variability over the same time period (baton rounds: 1007, 1327, 1123, 1382, 1278; ARUs: 11688, 13652, 13166, 13959, 12090). Only two services could provide details of medical consequences from use of incapacitant sprays, Taser, and baton rounds. No service could provide details of any related medical complications following use of firearms. Data collection and release are variable and inconsistent throughout English and Welsh police services and thus caution is needed in determining trends of UoF techniques. Deaths or injuries inflicted using UoF techniques result in much public scrutiny and the low level of data recorded in these cases is of concern. Common systems for recording use and adverse outcomes of UoF techniques are needed to inform the public and others who have concerns about such techniques.

Purpose: In the United Kingdom (UK) police restraint and control of detainees is undertaken by assorted means. Two types of incapacitant spray (IS) are approved by the UK Home Office for use: CS (o-chlorobenzylidine malononitrile, dissolved in an organic solvent--methyl iso-butyl ketone and pelargonic acid vanillyamide (PAVA). The aim of this study was to document the effects of incapacitant sprays, by symptom assessment and medical examination, within a few hours of deployment., Methods: A detailed proforma was produced to explore the nature of the arrest, the nature of exposure to the incapacitant spray, the type of incapacitant spray, the symptoms experienced and the medical findings., Results: 99 proformas were completed. 74 % were completed by detainees and 26 % were completed by police officers. 88 % were exposed to CS spray, the remainder to PAVA spray. The mean time of assessment after exposure was 2.8 ± 2.33 h (mean ± SD). The most frequent sites of IS contact were the face and scalp (n = 78), and exposure to the left and right eyes (n = 32). The most common symptoms were: painful eyes (n = 68); red eyes (n = 58); runny nose (n = 59); lacrimation (n = 55); nasal discomfort (n = 52); skin irritation (n = 49); and skin burning (n = 45). The most common medical findings were: conjunctival erythema (n = 34); skin erythema (n = 21); and rhinorrhea (n = 20)., Conclusions: Symptoms and signs of exposure to IS lasted longer than was expected (a mean of 2.8 h). Approximately 30 % of those exposed had ocular effects and 20 % had skin effects. The findings of this study will enable the guidelines on the expected effects and duration of symptoms resulting from exposure to incapacitant sprays to be reviewed and suggestions for their management to be refined.

The provision of clinical forensic medicine services is dependent on jurisdiction and relevant legal instruments. A needs analysis was performed to understand the current service provision within NSW and compare and contrast the service with other jurisdictions in Australia. The aim of this study was therefore to identify the roles, functions and clinical forensic medical services currently provided in the different Australian jurisdictions., (Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

The aim of the study was to determine the quality and nature of photographic images submitted to the National Injuries Database (part of the National Policing Improvement Agency) in the United Kingdom, for expert assessment and interpretation. A prospective analysis of cases (n = 50) were assessed for the number, origin, type and quality of images. Of 1,332 images in 50 cases submitted to the National Injuries Database, only 24% were appropriately labeled with an index; 5% were unfocussed; 64% had no rules or measurement scales; 0% had color charts or bars; 1.3% were of unidentifiable parts of the anatomy. The images sent to the National Injuries Database for interpretation originated from a variety of sources with no consistency in presentation. In particular, features such as rules or scales, color charts and appropriate labels with indexes, were absent in a variable number of cases, although these factors may at times be crucial to interpretation. It would be appropriate for standards to be developed and used for consistency in image capture, presentation and reproduction for interpretation for court settings in order to improve the quality of evidence available.

Little is known about the general healthcare needs of detainees in police custody. The aims of this study were to: determine the level of general health issues, diseases and/or pathology for detainees in police custody, and to determine how well those general health issues, diseases and/or pathology are being managed. This was done by a detailed analysis of healthcare issues of a cohort of detainees and reviewing intended and prescribed medication needs with current medication availability. In August 2007, a prospective detailed, anonymised, structured questionnaire survey was undertaken of 201 detainees in police custody in London, UK. Of these 83.6% consented to participate in the study. 85.1% of subjects were male; mean age was 33.9 years; 70.8% had English as a first language; 13.7% were of no fixed abode; 70.2% were registered with a general practitioner (primary care physician); 25% were already in contact with other healthcare teams; 7.1% had previously been sectioned under the Mental Health Act 1983; 16.7% had previously intentionally self-injured; 33.9% were dependent on heroin, 33.9% on crack cocaine; 25% on alcohol, 16.6% on benzodiazepines and 63.1% on cigarettes. 56% of subjects had active medical conditions; of those with active medical conditions 74% were prescribed medication for those medical conditions; only 3/70 had their medication available. 28/70 were not taking medication regularly, and many were not taking it at all. Three subjects who had deep vein thromboses were not taking their prescribed anticoagulants and six subjects with severe mental health issues were not taking their anti-psychotic medication. Mental health issues and depression predominated, but there was a very large range of mixed diseases and pathology. Asthma, epilepsy, diabetes, deep vein thrombosis, pulmonary embolism, hepatitis, and hypertension were all represented. The study has achieved its aims and has also shown that--in part because of the chaotic lifestyle of many detainees--appropriate care was not being rendered, thereby, putting both detainee, and potentially others coming into contact with them, at risk., (2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Introduction: Police services within England and Wales are required under the Police and Criminal Evidence Act 1984 to ensure appropriate healthcare to those detained in police custody (forensic medical services). Traditionally doctors have been used by police services to provide an appropriate level of care. Changes within the Act allowed other healthcare professionals (nurses and paramedics and emergency care practitioners) to be included in the provision of such services. The aim of this appears at least in part to have been to reduce the costs of providing such a service. In recent years police services within England and Wales have been outsourced to assorted commercial providers. There are now several different modes of delivery of forensic medical services, which are determined locally by separate police services., Aims: This study aimed (a) to determine the different modes of delivery of forensic medical services in England and Wales; (b) to determine the healthcare workload caused by Police and Criminal Evidence Act 1984 Codes of Practice; (c) to determine the relative costs of different service models and (d) to determine availability of such information from the police services., Methods: The study was undertaken in two parts--(a) a telephone survey of all police services, and (b) an application to each police service utilising the Freedom of Information Act 2000., Results: All police services (n=43) in England and Wales were contacted. Of the 41 forces that furnished detailed information; 13/41 had a doctor only service; 20/41 had a doctor/nurse service; 6/41 had a doctor/nurse/paramedic service; 1/41 had a doctor/emergency care practitioner service (who may be nurses or paramedic); 1/41 had a doctor/paramedic service. 23/43 services were outsourced to private commercial providers. Mean cost per patient contact (in 17/43 services which supplied data) was GBP 97.25. The cheapest cost per patient contact was the Metropolitan Police Service - a doctor only service (GBP 56.4), the highest Lincolnshire--a doctor only service (GBP 151.1). Mean cost for a doctor only service was GBP 97.1; for a doctor/nurse service--GBP 91.56 and for a doctor/nurse/paramedic service--GBP 115.76. There was no significant difference in costs per patient contact between a doctor only versus mixed HCP delivery of service. Relative costs and 95% confidence intervals expressed as a percentage show that a doctor only model was on average 3.4% lower than a mixed HCP provision, and that a non-outsourced service was on average 9.9% less than an outsourced service. No outsourced service in this study uses a doctor only model., Conclusions: The study shows that there was a complete lack of consistency in the recording and availability of information regarding forensic medical services for police services in England and Wales. The information that was obtained suggested that usage of such services varied greatly between police services and that costs of forensic medical services appear to be increased by the use of mixed healthcare professional service delivery and by using external commercial providers.

The number of people dependent on crack-cocaine in the UK has increased substantially in recent years. Some crack-cocaine users develop coarsening changes in the appearance of their hands after prolonged use of the drug. These changes have most often been recognized in females and include: (i) Perniosis with cold, numb hands, sometimes with perniotic hyperkeratosis over the knuckles.(ii) Finger pulp atrophy of the distal part of the pulps of some digits, especially the thumbs and index fingers.(iii) Claw-like curvature of the nails. As the distal pulp is lost, it can no longer splint the nail straight and so the nail curves, claw-like, and reminiscent of a parrot's beak as it clings to the new contour. As the pulp atrophy progresses, the nail eventually also becomes smaller.This triad may be due to ischemia consequent upon peripheral vasoconstriction induced by crack-cocaine. Early changes may resolve with abstinence. In the patients described the syndrome does not appear to be to related to intravenous drug usage. It may occur without concomitant use of heroin, whether smoked or via the intravenous route. The syndrome does not occur in all crack-cocaine users. It is hypothesized that those with a vasoreactive circulation (i.e., those with vasomotor instability/perniosis) are more susceptible to this reaction pattern. The syndrome consisting of the triad of perniosis, pulp atrophy and parrot-beaked clawing of the nails should alert the clinician to the possibility of prolonged crack-cocaine misuse.

Objectives: Peripheral parenteral nutrition is an option for short-term nutritional support in dogs which cannot be supported with enteral nutrition. The objective of this study was to examine the use of a three-in-one, 840 mOsmol/l peripheral parenteral nutrition product containing amino acids, lipids and glucose in separate compartments in dogs., Methods: Nine dogs were administered the three-in-one product, and two dogs were administered the amino acid part of the product, via a peripheral vein. Dogs were monitored for mechanical and metabolic complications., Results: Mechanical complications (apparent thrombus or thrombophlebitis) caused failure of infusion at a median of 36 hours. None of the dogs appeared to develop catheter-related sepsis. Using a 10-hour infusion period appeared to decrease the incidence of line failure. Mild and clinically non-significant hyperglycaemia was the only metabolic complication. In four of the dogs, serum folate, cobalamin and homocysteine concentrations were determined before and after peripheral parenteral nutrition administration. Oral and parenteral administration of methionine has been previously associated with lowered serum folate concentrations. Low serum folates and the subsequent hyperhomocysteinaemia have been associated with venous endothelial damage and venous thrombus in other species. Serum cobalamin also affects homocysteine metabolism. Median serum folate, cobalamin and homocysteine concentrations were not affected by the short-term administration of this three-in-one product., Clinical Significance: Using the product for 24 hours/day may require catheter replacement due to line failure. Other than line failure, which may be improved by 10- to 12-hour infusion times, this product was found to be safe and practical for short-term peripheral parenteral nutrition in dogs.

Introduction: Potentially preventable deaths in police custody include those which involve illicit drugs, alcohol and deliberate self-harm. Near miss incidents (NMI) that did not result in death have a crucial role in understanding risk factors in custody. Such research has not previously been undertaken. A program of research has been developed to study NMI, in order to better identify those at risk in police custody. For the purposes of this research, NMI have been defined as 'an unplanned and unforeseeable or unforeseen event that could have resulted, but did not result, in human death or may have resulted in injury or other adverse outcomes'. It was intended that the definition although broad, would not include simple accidents (e.g. slipping on urine in a cell) or trivial injury., Aims and Methods: The two aims of the study are (a) to determine whether it is realistic to attempt to assess NMI with the intention of identifying information of use in enhancing detainee care and (b) to assess how frequently NMIs occur and whether there are specific patterns. Pilot interviews were conducted with three forensic physicians practising in London, UK to create a structured questionnaire for all forensic physicians working in London. The questionnaire provided the basis of a retrospective recall survey of all forensic physicians working in London as Forensic Medical Examiners. The questionnaire was designed to assess the numbers of NMI, patterns in occurrence and relevant learning points within the previous 6 months. A covering letter, background questionnaire (exploring the background of the medical practitioner), copies of the survey, and reply paid envelopes were sent to each Forensic Medical Examiner (n=134) in London, contracted to provide forensic medical services for the Metropolitan Police Service. Data about all incidents were anonymized., Results: Ninety six (73%) Forensic Medical Examiners responded. Of these 18% were Principal grade, the remainder were Senior (24%), Standard (35%) and Assistant (23%). Thirty eight NMI were reported by 27 Forensic Medical Examiners (of all levels). The initial reason for police contact was recorded as alcohol (n=8), theft and robbery (n=7), warrants (n=4), violence (n=3), traffic violations (n=2) and single cases of drugs, murder and immigration offences. Of the main perceived cause of each NMI, illicit drugs were involved in 12/38, alcohol in 17/38, deliberate self-harm in 11/38, issues concerning searches, checks or rousing in 8/38, failure of inter-agency communications in 5/38, and possible resource issues in 4/38. In a number of cases more than one factor was involved., Conclusions: The information established about NMI is broadly consistent with documented patterns of deaths in police custody in England and Wales which supports the validity of the data. The next stage of this research will be a prospective six month study in which NMI will be analysed in order to learn lessons which may be utilised to attempt to prevent potentially avoidable deaths in police custody.

Aims and Methods: The aims of the study were to explore the current characteristics of drug misusers seen in police custody and identify trends or changes that have taken place in the last decade. A prospective, anonymised, structured questionnaire survey was undertaken of consenting consecutive, self-admitted illicit drug users seen by forensic physicians in police custody within the Metropolitan Police Service in London, UK in 2003., Results: 30% of detainees were dependent on heroin or crack cocaine. Drug users (n=113) were studied in 2003. 95.4% completed the questionnaire. 82% were male, 18% female. Mean age was 28.5 y (range 18-49). 80% were unemployed; significant mental health issues (e.g., schizophrenia) were present in 18%; 15% had alcohol dependence; heroin was the most frequently used drug (93%); crack cocaine -- 87%; mean daily cost of drugs -- heroin GBP 76 (range 20-240), crack GBP 81 (range 20-300). >50% users inject crack and heroin simultaneously. 56% used the intravenous route; 25% had shared needles; 100% had accessible sources of clean needles; 6.4% were hepatitis B positive; 42% were aware of hepatitis prophylaxis; hepatitis C positive -- 20.2%; 3.6% were HIV positive. Mean length of time of drug use was 7.5 y (range 1 month -- 20 years); 82% had served a previous prison sentence; 54% had used drugs in prison; 11% had used needles in prison; 3% of users stated they had started using in prison. 38% had been on rehabilitation programs; 11% had been on Drug Treatment and Testing; Orders (DTTO); 32% had used the services of Drug Arrest Referral Teams in police stations; 10% were in contact with Drug Teams at the time of assessment., Conclusions: In the last decade, there appears to be a substantial increase in the prevalence of drug use in this population -- particularly of crack cocaine. Treatment interventions are either not readily available, or not followed through. In very general terms, the illicit drug use problem appears to have significantly worsened in the population seen in police custody in London, UK, in the last decade although there is evidence that health education and harm reduction messages appear to have had some positive effects.

Hyperpigmentation after torture in darker skinned patients has regularly been noted, although its pathophysiology, and thus its forensic importance, has not previously been documented. Hyperpigmentation is not well described in the dermatological literature. It is the result of inflammation. Any inflammation can cause hyperpigmentation, and the shape of the resulting lesion can closely follow the contours of the site of original inflammatory response. This can be important in correlating the lesion with the alleged cause. It also helps to establish the differential diagnosis of the lesion, which also assists in assessing the degree of consistency between the lesion and the alleged cause. Patterns of hyperpigmentation can therefore, be helpful in assessing allegations of torture months or years after the event.

Carotid artery dissection followed by cerebral infarction as a result of blunt trauma can occur in a number of forensically relevant situations. We describe two such cases. In the first case, a 19-year-old female was involved in a road traffic accident, when her car crashed into the rear of another car. Initially, the young woman presented a minor head injury without loss of consciousness and minor bruising to the left side of the neck. After 48 h, she had developed confusion, speech difficulties, right facial nerve paralysis, and right hemiplegia. CT scan and carotid angiography showed cerebral ischemia with infarction in the territory of the middle left cerebral artery and complete dissection of the left carotid artery. In the second case, a 33-year-old male with depression attempted to hang himself. The rope gave way and he fell down. He had also taken a paracetamol, and a non-steroidal anti-inflammatory drug overdose. He did not lose consciousness but appeared withdrawn and depressed. Approximately 6 h later, his conscious state deteriorated. A CT scan revealed thrombosis of the left internal carotid artery, extending to the middle cerebral artery. The patient died. Both cases reinforce the need for full neurological assessment and review of any individual subject to blunt trauma to the neck, whether accidental or deliberate or where the history is incomplete. In the forensic setting, in particular, RTAs, suspension by the neck, strangulation, and garotting are all instances when examination and assessment must be thorough--and clear advice given--in the absence of any immediate signs or symptoms--that any new symptoms or signs require immediate and thorough neurological investigation. There should be low threshold for prolonged neurological observation or further neurovascular investigations such as ultrasound, CT or MRI scan or angiography, to minimize the risk of developing potentially fatal or incapacitating sequelae.

Objective: To determine how artificial nutrition support is used in hospitals in the United Kingdom and to determine whether there have been any alterations in practice when compared to similar studies in 1988 (1) and 1991 (2)., Design: A 94-question survey about artificial nutrition support (ANS) was sent to all district dietitians registered with the British Dietetic Association on 1 January 1994. Information was collected additionally from pharmacists, nutrition nurses and clinicians., Results: 66.6% of questionnaires distributed were returned with analysable information. Of the respondents, 37.3% had access to nutrition support teams, compared with 27% in 1988. The documentation of usage of nutrition support was poor, only 33% of respondents being able to accurately quantify administration of enteral nutrition (EN), and 53% parenteral nutrition (PN)., Conclusions: Despite increasing awareness about the role of artificial nutrition support, and the value of nutrition support teams there has only been a modest increase in the provision and monitoring of NSTs in the last 3 years. This has important implications when considering audit of such practices.

This review summarizes research studies published in recent years that are useful for clinicians considering the enteral route as a means of nutritional support for their patients. In this period, there has been a move away from emphasis on what nutrients are given to a more considered appraisal of how nutrients are provided. Thus, the technical aspects of enteral feeding have been refined, enabling a greater number of patients to be fed safely and effectively using the enteral route.

This report describes the use of a salivary alcohol measurement device in clinical forensic medicine, and concludes that it may be of use in assisting the diagnosis or the assessment of patients in the custodial setting.

Objective: to identify the prevalence of high-risk factors for infection with Human Immunodeficiency Virus (HIV) in individuals examined in clinical forensic medical practice and to determine opinions and attitudes about HIV in this patient group., Design: Anonymised questionnaire completed by consecutive individuals seen in clinical forensic medical practice., Setting: Police stations in London attended by Group IV forensic medical examiners., Subjects: 518 individuals examined in police stations (including prisoners and suspects, those detained in police custody, police officers and victims of crime)., Results: 164 (31.7%) individuals did not respond to the questionnaire because of: 1) refusal (12.6%) 2) inability because of drugs and/or alcohol (11.4%) 3) mental illness/disorder (4.2%) or 4) language difficulties (3.5%). 28.4% of the respondents were in at least one of the 'high-risk' categories for HIV infection. 26.5% were intravenous drug misusers; 15% were prostitutes; 9.8% (or their sexual partners) had lived in Central or East Africa since 1977; 5.9% were male homosexuals and 0.5% were haemophiliacs. 5.1% were infected with HIV or had Acquired Immunodeficiency Syndrome (AIDS). Only 28.8% of individuals always used condoms in short-term sexual relationships. 44.4% of respondents believed that everyone should be tested for HIV., Conclusion: Over one-quarter of the respondents were in higher-risk groups for infection with HIV. Almost one-third could or would not respond. It is concluded that it is not possible to identify by questionnaire, individuals at higher risk of HIV infection in forensic medical practice. This reinforces the necessity of observing good clinical practice to reduce contamination risks in this work environment. It is clear that education about risks for HIV infection is still much needed.

A prospective study was undertaken of 150 individuals in police custody, seen by a Forensic Medical Examiner (FME) for documentation of alleged assault and associated injuries. Ninety-six per cent consented to participate in the study of whom 86% were male. The mean age was 29.8 years. Most assaults (35%) were said to be unprovoked, 26% of injuries were alleged to have occurred at the time of arrest, 17% as a result of domestic incidents and 8% due to driving incidents. Twenty-nine per cent of examinees were victims of assault, 21% complained of alleged police assault and 20% were police officers injured during arrests. There was no significant difference between the mean ages of victims and assailants, and no significant difference in the proportions of each group under the influence of alcohol. Those individuals alleging police assault were all male, and significantly more likely to be unemployed and single. Victims of assault were significantly more likely to be female. Weapons were used in only 15% of cases. The head was the most common site of injury. Twenty-three per cent of the study population required hospital assessment. The study has characterized the different groups of individuals requiring medical assessment for assault and injury in police custody. The findings in this study population differ from similar studies undertaken in alternative settings.

Thirty two patients (74 (43-93) years; median, (range)) with dysphagia because of inoperable, unresectable or recurrent oesophagogastric carcinoma were treated by ethanol induced tumour necrosis (ETN). Endoscopic injection of absolute alcohol was performed using a variceal injector needle, with 0.5-1 ml aliquots injected retrogradely from distal to proximal tumour margin. Dilatation to 12 mm was used only if the endoscope would not traverse the stricture. In patients with total occlusion, injection into the proximal tumour was followed by a repeat endoscopy 3-7 days later. Dysphagia was graded from 0 = no dysphagia to 4 = total dysphagia. The significance of changes in the dysphagia grade after ETN were assessed using the Wilcoxon rank sum test. Results (median (range)) were as follows: stricture length = 5.0 cm (1-15). Dysphagia grade before treatment was 3 (2-4) improving after first treatment to 1 (0-3), p < 0.003. Best dysphagia grade achieved was 1 (0-3) and interval between treatments was 28.5 days (4-170). The volume of ethanol injected = 10 ml (1.5-29) and survival after first treatment was 93 days (6-660). The number of treatment sessions required to achieve best grade = 1 (1-3). There were no treatment complications. ETN significantly improves dysphagia. Results of palliation are similar to those of laser therapy, but can be achieved quickly and safely on a day case basis in most patients and at a small proportion of the cost.

Approximately 11% of individuals seen by forensic medical examiners in police custody in London are drug misusers. This prospective survey using an anonymized structured questionnaire attempted to define some of the characteristics of this selected group of drug misusers. The study was undertaken in Metropolitan Police Service stations (London, UK) within the area covered by Group IV Forensic Medical Examiners. One hundred and fifty consecutive drug misusers in police custody were assessed. Of these individuals 77% used heroin; 30% used both heroin and cocaine regularly; 72% were injecting drugs; 32% were being prescribed drugs (e.g. methadone) by general practitioners or drug agencies. Those individuals prescribed drugs spent a similar amount per day on illicit drugs as those who were not (100.30 pounds versus 106 pounds). Four per cent of individuals were HIV-positive; 25.7% were hepatitis-B positive. Only 9.7% were aware that prophylaxis for hepatitis-B was possible. Seventy-four per cent had served previous prison sentences and of those 82% had used class A controlled drugs whilst serving the sentence. It is concluded that drug misusers seen in police custody tend to be recidivists. It seems that some clear means of identifying and ensuring referral and attendance at an appropriate agency may be the only way to break the cycle of drug misuse, prison and further drug misuse in this highly (self) selected group of patients.

Elemental diet is as effective as corticosteroids in the treatment of previously untreated Crohn's disease. It is unclear whether a poor nutritional state is a prerequisite for efficacy of elemental diet, whether previously treated patients respond as well, or how duration of remission using elemental diet compares with corticosteroid induced remission. Forty two patients with active Crohn's disease were stratified for nutritional state and randomised to receive Vivonex TEN 2.1 l/day for four weeks, or 0.75 mg prednisolone/kg/day for two weeks and subsequent reducing doses. Nine of 22 (41%) patients assigned to nutritional treatment were intolerant of the diet. Thirty patients completed four weeks treatment. Disease activity decreased on elemental diet from mean (SEM) 4.8 (0.9) to 1.7 (0.6), p < 0.05, and on prednisolone from 5.3 (0.5) to 1.9 (0.6), p < 0.05. For each treatment, nourished and malnourished patients responded similarly. Patients with longstanding disease responded as well as newly diagnosed patients. The probability of maintaining remission at six months was 0.67 after prednisolone, 0.28 after elemental diet, and at one year was 0.35 after prednisolone and 0.09 after elemental diet, p < 0.05. When tolerated, elemental diet is as effective in the short term as prednisolone in newly and previously diagnosed Crohn's disease, and its benefit is independent of nutritional state. The subsequent relapse rate after elemental diet induced remission, however, is greater than after treatment with prednisolone.

A detailed survey questionnaire compiled by the executive committee of Patients on Intravenous and Nasogastric Nutrition Therapy (PINNT) was circulated in November 1991 to the postal addresses of all full (patient) members of PINNT in the UK. The objective of the survey was to identify current practices and problems of home nutrition support as seen from the patients perspective. 128 questionnaires were distributed. 87 (68%) analysable questionnaires were completed and returned. 77 were for parenteral nutrition (HPN) patients and 10 for patients on enteral nutrition (HEN). Areas of concern for patients include the practicalities of administration of lipid and additives, and problems associated with the appearance of air in infusion bags. Although most patients appeared happy with the home nutrition support services 18% commented on particular negative aspects. This survey highlights such areas which may not be identified during routine patient/clinician contact.

We present a 7-year consecutive, nonselected, single-center series of patients (n = 140) submitted to surgery for esophageal or upper gastric malignancy. Follow-up data are complete for 96.4% of patients. Of 114 intrathoracic anastomoses, 74 (65%) were esophagogastric and 40 (35%) were esophagojejunal. Unresectable lesions were present in 26 (19%) patients. Age (mean +/- sd 64.6 +/- 11.1 years), and sex distribution were similar in all groups, while 36% of patients were over 70 years. There was no significant difference in the time from the onset of symptoms to presentation between the groups (p < 0.05). The values of admission hemoglobin, serum albumin, PaO2 or peak expiratory flow rate did not correlate with survival. There was no significant difference in 30-day operative mortality between the three procedures - esophagectomy 5%, thoraco-abdominal gastrectomy 10.8% and unresectable 11.5% (p > 0.05). The incidence of respiratory complications was the same whether a right (30%) or left (35%) thoracotomy was performed. Some 33% of patients were discharged from hospital after 14 days and 72% after 21 days (12.9% died in hospital). One-year survival was 33.4% for esophagectomy, 37.5% for total gastrectomy and 6% for unresectable lesions. The esophagectomy versus total gastrectomy survival curves were not significantly different, but there was a significant survival advantage when patients undergoing esophagectomy were compared with those who had unresectable tumors (0.02 > p > 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

The present study was undertaken to investigate the short term clinical efficacy of oral dietary supplements administered post-operatively to patients undergoing predetermined moderate to severe gastrointestinal surgery. Trial end points for comparison included effects of oral dietary supplements on nutritional intake, nutritional status and incidence of serious complications. 54 patients who were scheduled to undergo predetermined moderate to major gastrointestinal surgical procedures entered the study. They were randomly assigned to receive a normal ward diet post-operatively or the same diet supplemented ad libitum by an oral nutritional sip feed. The study period was defined as commencing from the day patients were adjudged to be capable of ingesting 'free fluids' to the day of hospital discharge. 40 patients (20 in each group) completed the study. The mean daily energy intake (KCal/day) assessed from 7 day food diaries was significantly higher in the treatment group (1833 +/- SEM 99) than in the control group (1108 +/- 56, p < 0.0001). This increase occurred not only as a consequence of energy intake from the oral dietary supplements (470 +/- 30) but also because more energy was consumed from the ward diet by the treatment than the control patients (1353 +/- 92 vs 1108 +/- 56, p < 0.02). The mean daily protein intake g/day in the treatment group (66.0 +/- 3.4) was also greater than in the control group (52.9 +/- 29 p < 0.0001). This difference was due solely to the intake in protein from the oral dietary supplements (15.7 +/- 1.0), protein intake from the ward diet being similar in the treatment (50.1 +/- 3.2) and control (52.9 +/- 29) groups. Patients in the treatment group maintained their pre-operative weight where as control patients had lostsignificant amount of their pre-operative weight by study day 3 (4.5 +/- 12 kg and by discharge (4.7 +/- 1.2 kg, p < 0.02). Pre-operative muscle function as evidenced by grip strength dynamometry decreased to a greater extent in the control than treatment group patients by study day 3 (14.6 +/- 2.2 KPa vs 2.8 +/- 2.4 < 0.03) and by discharge (10.4 +/- 3.1 KPa vs 0.10 +/- 1.9 p < 0.03). The incidence of serious infections (pneumonia, wound infection) was significantly higher in the control group (10) than in the treatment group (3, p < 0.02). It is concluded that the prescription of oral dietary supplements on an ad libitum basis to post-operative patients undergoing moderate to major gastrointestinal surgery results in clinically significant short term benefits.

Objective - to determine current clinical practice of nutrition support in hospitals in the UK and to determine whether there have been any apparent changes in practices since 1988. Design - An 81 question survey about enteral and parenteral nutriton was sent to all District Dietitians registered with the British Dietetic Association. Information was collected additionally from pharmacists and clinicians. Results - 61.2% of questionnaires distributed were completed and returned. 32.5% of respondents had access to nutrition support teams, compared with 27% in 1988. The documentation of usage of nutrition support was poor, only 33% being able to accurately quantify administation of enteral nutrition, and 53% parenteral nutrition. Since 1988 the number of respondents using peripheral parenteral nutrition had doubled to 15%. Those using percutaneous gastrostomies had increased from 6% to 74%. Those using respiratory enteral diet formulations had quadrupled to 33%. There have been no other apparent major changes in nutrition support practice in the UK, in the last 3 years. Conclusions - Despite increasing awareness about the role of artificial nutrition support, and the value of Nutrition Support Teams there has been little or no progress in the provision or monitoring of support in the last 3 years. This has important implications when considering audit of such practices.

A prospective clinical study in three phases was performed to determine whether it was possible that enteral diet containers could become contaminated as a result of endogenous organisms ascending retrogradely from the enteral feeding tube via the giving set, and if this did occur whether the incidence could be altered by modifying enteral delivery systems. Each phase observed patients on enteral feeding over a 48-hour study period (phase I, n = 18; phase II, n = 17; phase III, n = 18). Each patient was prescribed an enteral diet of 2 L/24 h administered by continuous pump infusion from a closed 1-L sterile diet container. Four containers were used for each patient, and one giving set was used in the 48-hour period. Diet samples were taken at 12-hour intervals: two from the giving set before and after flushing with residual diet, and one from the diet container. Phases differed only in the design of the giving set: phase I had no drip chamber, phase II had a drip chamber, phase III had a drip chamber and an anti-reflux ball valve at the distal end. Both phase I and III had greater numbers of giving set samples colonized at 24, 36, and 48 hours. In phase I, 3 of 14 sterile diet containers were colonized with greater than 10(4) colony-forming organisms/mL of diet at 48 hours. Only phase II had no organisms contaminating the containers at 48 hours. We conclude that the retrograde spread of organisms from patient to sterile diet container does occur in clinical practice, and that a drip chamber in the giving set may prevent the problem.(ABSTRACT TRUNCATED AT 250 WORDS)

Glycine has been regarded as a poor source of nitrogen for total parenteral nutrition. Two prospective randomised cross over controlled clinical trials were undertaken to compare the efficacy of high and low glycine containing amino acid solutions in parenterally fed malnourished hypoalbuminaemic patients with gastrointestinal disease. In the first study (n = 9), amino acid solutions in which glycine accounted for 23% and 4% of total nitrogen were compared. No statistically significant difference was found in urea nitrogen/total urinary nitrogen excretion (mean (SEM) 83.4 (1.4) v 81.6 (1.7)%, p = 0.31), nitrogen balance (-1.9 (2.4) v -0.6 (2.0) g/day, p = 0.31) or plasma protein concentrations and blood urea nitrogen. In the second extended study (n = 5), there was no significant difference in net whole body protein synthesis (+1.3 (4.7) v-0.2 (3.7) mg/kg/hour, p = 0.69) or fractional (0.403 (0.070) v 0.480 (0.41)%/hour, p = 0.68) and absolute albumin synthesis rates (6.0 (0.9) v 7.2 (0.06) mg/kg/hour, p = 0.22), on comparing solutions of 25% and 8% glycine nitrogen. In addition, a significantly higher proportion of total urinary nitrogen comprised urea when patients received the low glycine containing amino acid source (81.4 (2.5) v 83.8 (3.2)%, p = 0.04). It is concluded that there are no apparent short term nutritional or metabolic disadvantages to using amino acid solutions that contain up to 25% of nitrogen as glycine in total parenteral nutrition.

A double-blind, randomised, placebo-controlled study was undertaken to determine whether topical application of a nonsteroidal anti-inflammatory gel to skin overlying peripheral vein cannula sites has a role in reducing the incidence or delaying the onset of peripheral vein thrombophlebitis. Fifty normal subjects had intravenous cannulae placed in right and left arms. Subjects were randomised to receive twice daily application of either active nonsteroidal anti-inflammatory gel or placebo gel to each cannula site. Cannula sites were observed and signs and symptoms of inflammation recorded up to 108 h. If any site had signs extending beyond 2 cm then the cannula was removed. Cannula sites that had 'active' gel applied had half the incidence of marked signs at 108 h (44% vs 22%, p less than 0.05). These results suggest that local application of topical nonsteroidal anti-inflammatory gel to cannula sites may have a significant role to play in the prevention of peripheral vein thrombophlebitis.

Percutaneous endoscopic insertion of gastrostomy tubes is a technique becoming more widely used in the UK. It allows insertion of a gastrostomy tube without laparotomy, under local anaesthesia and sedation, and so operative insertion may eventually become a rarity. We report on our successful early experience with a new gastrostomy tube (Bower PEG) which does not require endoscopy if eventual removal is required, and describe the methods of insertion and removal.

A series of 54 normal subjects were randomised to have either a Vialon or a PTFE-Teflon peripheral vein cannula inserted in a vein in each forearm to observe the development of thrombophlebitis. Cannulas were inspected twice daily for up to 5 days to observe the development of three signs, erythema, oedema or hardness and one symptom, pain. Each sign and symptom was recorded twice daily at three points, the cannula insertion site, the mid-point of the cannula and the cannula tip. The degree of change was recorded as less than 1, 1-2 and greater than 2 cm. Any cannula causing any sign greater than 2 cm was removed. By the end of the study over 40% of both types of cannula had been removed. There were no significant differences between the numbers of each type of cannula removed at any time point throughout the duration of the study. There were no significant differences in the amounts of erythema or hardness, but minimally increased swelling was observed at the mid-point of the PTFE-Teflon cannulas (P = 0.022). Despite the theoretical superiority of Vialon as a cannula material, under controlled conditions there appears to be little difference in its inherent capacity to cause the thrombophlebitis.

A 60-year-old female patient with a 3-year history of nausea underwent oesophagogastroduodenoscopy. Red lesions were found in the cervical oesophagus: one of 2 cm and the other less than 1 cm. These lesions were biopsied and the larger lesion showed typical gastric mucosa. Following 40 mg/day omeprazole for 3 days all symptoms disappeared. Treatment was stopped after the patient remained symptom-free for 4 weeks.

We have reviewed and discussed data concerning the development of hepatobiliary dysfunction in the patient requiring TPN. The data above can be summarised in a short statement--TPN-related hepatobiliary dysfunction is multifactorial. Despite all the factors discussed, the patients underlying disease state and the severity of the illness may be the most significant factor in the development of hepatobiliary dysfunction. With our current state of knowledge it is only possible for the clinician to be aware which of his patients are most likely to develop problems, and to forecast the type of dysfunction that is most likely to occur. There is no treatment--apart from stopping TPN--but there are certain methods by which the incidence and degree of dysfunction may be minimised, or some of the complications (e.g. gallstones) treated. Fortunately in most cases the degree of dysfunction is both self-limiting and reversible on cessation of TPN.

Sixty nine patients with non-ulcer dyspepsia have been studied with endoscopy, biopsy, quick urease (CLO) test, Helicobacter pylori culture, and the 13C-urea breath test before and after treatment with tripotassium dicitratobismuthane (DeNol) two tablets twice daily for four weeks. Symptoms of non-ulcer dyspepsia were recorded using a standard questionnaire. Using H pylori culture as the gold standard, the sensitivity of the 13C-urea breath test was 90%, the specificity 98.6%, and the accuracy 94.8% with a positive predictive value of 98.2% and a negative predictive value of 92.5%. Conversion rate from H pylori positive to negative status after treatment with tripotassium dicitratobismuthate was 17.9%. Symptoms of non-ulcer dyspepsia improved appreciably after treatment irrespective of H pylori status. The 13C-urea breath test is an accurate research tool suitable for serial testing and population surveys.

This case report describes the complication of peristomal abscess formation associated with the insertion of a percutaneous endoscopic gastrostomy (PEG). The formation of a peristomal anterior abdominal wall abscess in this patient was associated with the failure to give prophylactic antibiotics. The development of this potentially fatal complication may be avoided by strict observance of insertion protocols. This case was treated by removal of the gastrostomy tube after diagnosis which allowed drainage of the abscess. In similar cases of occult abscess formation, where symptoms are present but signs are absent, ultrasonography may be useful in diagnosis.
