Esophageal Causes of Sudden and Unexpected Death

JOURNAL OF FORENSIC SCIENCES, Issue 2 2006
Roger W. Byard M.D.
ABSTRACT: Gastrointestinal conditions are uncommon causes of sudden and/or unexpected death as compared to cardiovascular diseases, motor vehicle trauma, or suicide, and may involve an array of fatal mechanisms. Lethal esophageal conditions are encountered even less often, the manifestations of which include acute upper airway occlusion from tumors or foreign material, intraluminal hemorrhage from vascular abnormalities, or perforation with fistula formation resulting in hemorrhage and sepsis. When encountered at autopsy, a particular condition may also be a manifestation of a disease that does not primarily involve the esophagus. For this reason, a detailed autopsy investigation is required for evidence of systemic or remote disease when lesions are found within the esophagus. In this report, possible life-threatening esophageal conditions are reviewed with a description of lethal mechanisms, mention of rare associated diseases, and comment on difficulties that may arise at autopsy in the evaluation of such cases.

Microbial diversity of inflamed and noninflamed gut biopsy tissues in inflammatory bowel disease

INFLAMMATORY BOWEL DISEASES, Issue 6 2007
Shadi Sepehri MD
Abstract Background: Inflammatory bowel disease (IBD) is a chronic gastrointestinal condition without any known cause or cure. An imbalance in normal gut biota has been identified as an important factor in the inflammatory process. Methods: Fifty-eight biopsies from Crohn's disease (CD, n = 10), ulcerative colitis (UC, n = 15), and healthy controls (n = 16) were taken from a population-based case-control study. Automated ribosomal intergenic spacer analysis (ARISA) and terminal restriction fragment length polymorphisms (T-RFLP) were used as molecular tools to investigate the intestinal microbiota in these biopsies. Results: ARISA and T-RFLP data did not allow a high level of clustering based on disease designation. However, if clustering was done based on the inflammation criteria, the majority of biopsies grouped either into inflamed or noninflamed groups. We conducted statistical analyses using incidence-based species richness and diversity as well as the similarity measures. These indices suggested that the noninflamed tissues form an intermediate population between controls and inflamed tissue for both CD and UC. Of particular interest was that species richness increased from control to noninflamed tissue, and then declined in fully inflamed tissue. Conclusions: We hypothesize that there is a recruitment phase in which potentially pathogenic bacteria colonize tissue, and once the inflammation sets in, a decline in diversity occurs that may be a byproduct of the inflammatory process. Furthermore, we suspect that a better knowledge of the microbial species in the noninflamed tissue, thus before inflammation sets in, holds the clues to the microbial pathogenesis of IBD.

Psychogastroenterology: a call for psychological input in Australian gastroenterology clinics

INTERNAL MEDICINE JOURNAL, Issue 2 2009
A. Mikocka-Walus
Abstract Gastroenterologists should be able to refer patients directly to psychologists with full Medicare reimbursement. Psychological comorbidities are frequently seen in patients with gastrointestinal conditions. However, time pressure and lack of expertise in non-medical therapies of psychological problems prevent gastroenterologists from initiating psychological treatment although such treatment may improve patients' outcomes and reduce health-care utilization. Psychologists are needed as part of the multidisciplinary team in gastroenterology clinics in Australia to take the leading role in the psychological management of those patients by contributing to screening, faster diagnosis and treatment of depression and anxiety disorders in particular.

Clinical medication review by a pharmacist of elderly people living in care homes: pharmacist interventions

INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 2 2007
David P Alldred research clinical pharmacist
Objectives To describe the rate and nature of pharmacist interventions following clinical medication review of elderly people living in care homes. Setting Care home residents aged 65+ years, prescribed at least one repeat medication, living in nursing, residential and mixed care homes for older people in Leeds, UK. Method Analysis of data from care home residents receiving clinical medication review in the intervention arm of a randomised controlled trial. Intervention outcomes for each medicine were evaluated for each resident. Key findings Three-hundred and thirty-one residents were randomised to receive a clinical medication review and 315 (95%) were reviewed by the study pharmacist; 256 (77%) residents had at least one recommendation made to the general practitioner. For the 2280 medicines prescribed, there were 672 medicine-related interventions: medicines for cardiovascular system (167 (25%)), nutrition and blood (121 (18%)), central nervous system (113 (17%)) and gastrointestinal conditions (86 (13%)) accounted for 487 (73%) of medicine-related interventions. There were 75 non-medicine-related interventions. The most common interventions were ,technical' (225 (30%)), ,test to monitor medicine' (161 (22%)), ,stop drug' (100 (13%)), ,test to monitor conditions' (75 (10%)), ,start drug' (76 (10%)), ,alter dose' (40 (5%)) and ,switch drug' (37 (5%)). Recommendations to stop a medicine were most common for CNS drugs (32 (32%)). The most common medicine to be recommended to be started was calcium and vitamin D (45 (59%)). Following a recommendation to test to monitor a medicine, 23 (14%) medicines required a change. Conclusions This study has demonstrated that clinical medication review by a pharmacist can identify medicine problems in approximately 80% of care home residents, requiring intervention in 1 in 4 of their prescribed medications.

Quantifying the ,hidden' lactose in drugs used for the treatment of gastrointestinal conditions

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2009
P. EADALA
Summary Background, Lactose intolerance affects 70% of the world population and may result in abdominal and systemic symptoms. Treatment focuses predominantly on the dietary restriction of food products containing lactose. Lactose is the most common form of excipient used in drug formulations and may be overlooked when advising these patients. Aim, To identify and quantify the amount of lactose in medications used for the treatment of gastrointestinal disorders and to identify ,lactose-free' preparations. Methods, Medications used for the treatment of gastrointestinal disorders were identified from the British National Formulary (BNF). Their formulation including excipients was obtained from the Medicines Compendium. The lactose content and quantity in selected medications was measured using high-performance liquid chromatography (HPLC). Results, A wide range of medications prescribed for the treatment of gastrointestinal conditions contain lactose. We have quantified the lactose content in a selection of medications using HPLC. Lactose is present in amounts that may contribute towards symptoms. Lactose-free alternatives were also identified. Conclusions, Lactose is present in a range of medications and may contribute towards symptoms. This may not be recognized by the prescribing doctor as excipients are not listed in the BNF, and the quantity of lactose is not listed on the label or in the accompanying manufacturer's leaflet.

Neuromodulatory Processes of the Brain,Gut Axis

NEUROMODULATION, Issue 4 2008
Alexandru Gaman MD
ABSTRACT Brain,gut axis represents a complex reflex circuit that integrates the communication between cortex and the digestive system. Disturbances of the neuromodulatory processes in the brain,gut axis generate functional digestive disorders mainly centered on the pain symptoms and motility disorders. This article reviews structural and pathophysiologic aspects of the brain,gut axis and explains how the neuromodulatory interventions currently used in order to treat gastrointestinal conditions related to the brain,gut axis disturbances. The neuromodulation can be realized by pharmacologic targeting mainly receptors in the periphery or using electrical stimulation applied at different levels of the nervous system or directly in the muscular layers of the bowels resulting in modulation of the digestive system activity. The efficacy of the methods using electrostimulation is dependent on the parameters of the physical system used: amplitude, frequency, burst time of the electrical current, and also the positioning of the electrodes. While pharmacologic interventions are largely used at the moment, neuromodulatory interventions involving electrical stimulation showed clinical efficacy in research trials and have promise.

Gastric contents in pediatric patients following bone marrow transplantation

PEDIATRIC ANESTHESIA, Issue 7 2010
GHASSAN WAHBEH MD
Summary Background:, Graft versus host disease (GVHD) of the gut is thought to delay gastric emptying and so may increase the risk of aspirating retained contents while under anesthesia. Knowing that gastric emptying is delayed in patients with GVHD might lead one to choose to intubate the trachea for all patients with suspected GVHD, who present for diagnostic esophagogastricduodenoscopy (EGD). We are not aware of published data that gives specific guidance as to the need for intubation in the pediatric bone marrow or stem cell transplantation (BMT) population. This review was intended to evaluate the gastric contents (pH and volume) in this group of patients, to provide anesthesiologists with data that would inform their decisions about airway management for these patients. Methods:, Retrospective chart review of patients ,19 years of age undergoing EGD between 2004 and 2006. Gastric content volume and pH were measured in addition to underlying disease state and treatment. We compared BMT patients with suspected GVHD to nontransplant patients with other underlying gastrointestinal conditions. Results:, Data were obtained for 77 patients post-BMT undergoing EGD, including 40 patients whose biopsies and endoscopic findings were positive for GVHD, and 37 patients with no demonstrable GVHD. Records of 144 non-BMT patients undergoing EGD within the same study period were also reviewed. Conclusion:, Patients in the BMT group overall did not have higher volumes when compared to non-BMT patients. A secondary comparison of BMT patients who were found to have GVHD vs BMT patients without GVHD suggests that gastric content volume may be elevated with GVHD. Patients in the BMT group had statistically significantly higher gastric pH than patients in the non-BMT group. It is possible that the higher gastric volume in the GVHD-positive group could put them at slightly higher risk for aspiration, but the severity of any pneumonitis, should aspiration occur, might be mitigated, by the tendency toward a higher gastric pH in the BMT patients.

Latest news and product developments

PRESCRIBER, Issue 23-24 2007
Article first published online: 8 JAN 200
Cervical cancer risk falls after COC use ends Combined oral contraceptives (COCs) are associated with a slight increase in the risk of cervical cancer but this diminishes with time after use ends, an international study has shown (Lancet 2007;370:1609,21). Analysis of data for 16 573 women with and 35 509 women without cervical cancer confirmed that using a COC for 10 years between the ages of 20 and 30 increases the incidence of invasive cervical cancer from 3.8 to 4.5 per 1000 by age 50. However, the excess risk disappears 10 years after cessation of use. , A new analysis of the US Nurses' Health Study suggests that protection against ovarian cancer does not persist beyond 20 years after cessation of COC use. This study also showed that tubal ligation is associated with reduced risk of ovarian cancer (Am J Epidemiol 2007; 166;894,901). Pharmaceutical services fund moves to PCTs The ,global sum' that provides central funding for NHS pharmaceutical services is being shifted to PCTs. The Government has included legislation for the change in the recent Health and Social Care Bill. The fund pays the fees and allowances for pharmacy contractors and appliance contractors. The Government says this is a ,natural progression and in keeping with moves to devolve NHS funds to the frontline' that will enable PCTs to manage pharmacy services better by ,encouraging best prescribing practice'. Fewer fluoroquinolones in the community Restricting prescribing of fluoroquinolone antibacterials does not increase hospital admissions for infection among older people, say Canadian researchers (Am J Med 2007;120:893,900). Their analysis of an Ontario medical database shows that, in a community where fluoroquinolones were the most widely prescribed antibacterials, a one-third reduction in prescribing was not followed by an increase in hospital admissions for infectious episodes in the over,65s. On the contrary, there was a 32 per cent reduction in admissions for gastrointestinal conditions. FDA reports increased TB risk with infliximab The US Food and Drug Administration has published an analysis of cases of TB associated with infliximab (Remicade) detected via its spontaneous adverse event reporting scheme (Ann Intern Med 2007;147: 699,702). In 2001 the FDA placed a warning about the risk of TB on product labelling for infliximab and advised testing for TB before initiating treatment. This analysis of 130 cases of TB since reported in patients treated with infliximab found that 45 per cent had developed extra-pulmonary disease; risk factors included use of immunosuppressants (including methotrexate), a history of TB and time spent in an endemic area. Of 67 cases in which treatment was initiated after the warning was issued, 34 with a negative tuberculin skin test developed TB after receiving infliximab. MHRA announces anticounterfeit strategy The UK is a transit point, distribution hub and end-user of counterfeit medicines, says the MHRA in its first anti-counterfeiting strategy (www.mhra.gov.uk). Counterfeits have been detected in the legitimate supply chain with increasing frequency since 2004, resulting in nine batch recalls and a further five incidents detected at wholesale level. The MHRA's proposed approach includes: communication to raise awareness of the risk and facilitate reporting, collaboration with the WHO, the industry and law enforcement agencies, and targeted surveillance, prosecution and regulation. Evidence lacking for choosing DMARD There is insufficient evidence to choose one DMARD or biological agent over another in patients with RA, US investigators say (www.annals.org/cgi/content/abstract/0000605,20080115000192v1). Their systematic review of meta-analyses and intervention and observational trials found no evidence of differences among DMARDs or anti-TNF agents. Mono-therapy with an anti-TNF agent was associated with superior radiographic but not clinical outcomes; methotrexate plus an anti-TNF agent was superior in clinical and functional terms to either drug given alone. Be alert to psychiatric ADRs with rimonabant Clinicians should remain alert for the development of anxiety, depression and an increased risk of suicide with rimonabant (Acomplia), say Danish investigators (Lancet 2007;370:1706,13). Their meta-analysis of four randomised trials involving a total of 4105 patients showed that rimonabant was associated with an increased risk of serious adverse events (odds ratio 1.4; number needed to harm, NNH, 59), including a 2.5,fold increased risk of depression (NNH 49) and a threefold increased risk of anxiety (NNH 166). Following a warning from the FDA of an increased risk of suicide with rimonabant, the authors say their findings indicate a need for ,increased alertness by physicians to these potentially severe psychiatric adverse reactions'. New strategy for NHS medicines information The UK Medicines Information Service (www.ukmi.nhs.uk) has published its new management strategy setting out how it will respond to recent developments in the NHS. Developments include greater access to information for patients, support for nontraditional prescribers and new commissioning arrangements. New antiretroviral Maraviroc (Celsentri) is the first CCR5 antagonist to be introduced for the treatment of HIV infection. CCR5 is one of two co-receptors to which the HIV virus must attach to achieve cell entry. Maraviroc is licensed for use by treatment-experienced patients in whom only CCR5-tropic HIV-1 is detectable. The recommended dose ranges from 150 to 600mg twice daily depending on interactions with concurrent medication. Dimeticone superior Dimeticone 4 per cent lotion (Hedrin) is superior to malathion 0.5 per cent in the eradication of head lice, a UK study in 58 children and 15 adults has shown (PLoS ONE 2007;2: e1127. doi:10.1371/journal.pone. 0001127). Two applications of dimeticone lotion one week apart cleared active infestation in 70 per cent of participants compared with 33 per cent in those who used a single application of malathion.

Reason for Visit: Is Migrant Health Care That Different?

THE JOURNAL OF RURAL HEALTH, Issue 2 2008
George F. Henning MD
ABSTRACT:,Purpose:The purpose of this pilot study was to determine the reasons for which migrant agricultural workers in Pennsylvania seek health care.Methods:Participants were individuals 14 years of age and over, actively involved in agricultural labor and presenting for medical care at 6 migrant health care centers. Bilingual health care providers randomly selected and interviewed the participants.Findings:The most commonly reported reason for visiting the health care provider was for physical examination. The most frequent acute problems were related to the musculoskeletal and integumentary systems. Frequently cited problems in the medical history were hypertension, musculoskeletal/back pain, and gastrointestinal conditions. Most medications being taken were for cardiovascular or pain-related problems.Conclusions:These results suggest that migrant workers present with medical problems that are similar to those of the general primary care population. Many problems were recurrent and represented common chronic medical conditions. [source]
