The association of chronic kidney disease and dialysis treatment with foot ulceration and major amputation

Objective The objective of this study was to investigate the risk of chronic kidney disease (CKD) stage 4-5 and dialysis treatment on incidence of foot ulceration and major lower extremity amputation in comparison to CKD stage 3. Methods In this retrospective study, all individuals who visited our hospital between 2006 and 2012 because of CKD stages 3 to 5 or dialysis treatment were included. Medical records were reviewed for incidence of foot ulceration and major amputation. The time from CKD 3, CKD 4-5, and dialysis treatment until first foot ulceration and first major lower extremity amputation was calculated and analyzed by Kaplan-Meier curves and multivariate Cox proportional hazards model. Diabetes mellitus, peripheral arterial disease, peripheral neuropathy, and foot deformities were included for potential confounding. Results A total of 669 individuals were included: 539 in CKD 3, 540 in CKD 4-5, and 259 in dialysis treatment (individuals could progress from one group to the next). Unadjusted foot ulcer incidence rates per 1000 patients per year were 12 for CKD 3, 47 for CKD 4-5, and 104 for dialysis (P < .001). In multivariate analyses, the hazard ratio for incidence of foot ulceration was 4.0 (95% confidence interval [CI], 2.6-6.3) in CKD 4-5 and 7.6 (95% CI, 4.8-12.1) in dialysis treatment compared with CKD 3. Hazard ratios for incidence of major amputation were 9.5 (95% CI, 2.1-43.0) and 15 (95% CI, 3.3-71.0), respectively. Conclusions CKD 4-5 and dialysis treatment are independent risk factors for foot ulceration and major amputation compared with CKD 3. Maximum effort is needed in daily clinical practice to prevent foot ulcers and their devastating consequences in all individuals with CKD 4-5 or dialysis treatment.

Assessment of signs of foot infection in diabetes patients using photographic foot imaging and infrared thermography

Background Patients with diabetic foot disease require frequent screening to prevent complications and may be helped through telemedical home monitoring. Within this context, the goal was to determine the validity and reliability of assessing diabetic foot infection using photographic foot imaging and infrared thermography. Subjects and Methods For 38 patients with diabetes who presented with a foot infection or were admitted to the hospital with a foot-related complication, photographs of the plantar foot surface using a photographic imaging device and temperature data from six plantar regions using an infrared thermometer were obtained. A temperature difference between feet of > 2.2 °C defined a ''hotspot.'' Two independent observers assessed each foot for presence of foot infection, both live (using the Perfusion-Extent-Depth- Infection-Sensation classification) and from photographs 2 and 4 weeks later (for presence of erythema and ulcers). Agreement in diagnosis between live assessment and (the combination of ) photographic assessment and temperature recordings was calculated. Results Diagnosis of infection from photographs was specific (> 85%) but not very sensitive (< 60%). Diagnosis based on hotspots present was sensitive (> 90%) but not very specific (<25%). Diagnosis based on the combination of photographic and temperature assessments was both sensitive (> 60%) and specific (> 79%). Intra-observer agreement between photographic assessments was good (Cohen's j = 0.77 and 0.52 for both observers). Conclusions Diagnosis of foot infection in patients with diabetes seems valid and reliable using photographic imaging in combination with infrared thermography. This supports the intended use of these modalities for the home monitoring of high-risk patients with diabetes to facilitate early diagnosis of signs of foot infection.

How do Australian podiatrists manage patients with diabetes The Australian diabetic foot management survey

Background Diabetic foot complications are the leading cause of lower extremity amputation and diabetes-related hospitalisation in Australia. Studies demonstrate significant reductions in amputations and hospitalisation when health professionals implement best practice management. Whilst other nations have surveyed health professionals on specific diabetic foot management, to the best of the authors’ knowledge this appears not to have occurred in Australia. The primary aim of this study was to examine Australian podiatrists’ diabetic foot management compared with best practice recommendations by the Australian National Health Medical Research Council. Methods A 36-item Australian Diabetic Foot Management survey, employing seven-point Likert scales (0 = Never; 7 = Always) to measure multiple aspects of best practice diabetic foot management was developed. The survey was briefly tested for face and content validity. The survey was electronically distributed to Australian podiatrists via professional associations. Demographics including sex, years treating patients with diabetes, employment-sector and patient numbers were also collected. Chi-squared and Mann Whitney U tests were used to test differences between sub-groups. Results Three hundred and eleven podiatrists responded; 222 (71%) were female, 158 (51%) from the public sector and 11–15 years median experience. Participants reported treating a median of 21–30 diabetes patients each week, including 1–5 with foot ulcers. Overall, participants registered median scores of at least “very often” (>6) in their use of most items covering best practice diabetic foot management. Notable exceptions were: “never” (1 (1 – 3)) using total contact casting, “sometimes” (4 (2 – 5)) performing an ankle brachial index, “sometimes” (4 (1 – 6)) using University of Texas Wound Classification System, and “sometimes” (4 (3 – 6) referring to specialist multi-disciplinary foot teams. Public sector podiatrists reported higher use or access on all those items compared to private sector podiatrists (p < 0.01). Conclusions This study provides the first baseline information on Australian podiatrists’ adherence to best practice diabetic foot guidelines. It appears podiatrists manage large caseloads of people with diabetes and are generally implementing best practice guidelines recommendations with some notable exceptions. Further studies are required to identify barriers to implementing these recommendations to ensure all Australians with diabetes have access to best practice care to prevent amputations.

The tired foot. The effects of physical activity, energy expenditure and sleep on the diabetic foot population

Background The most common pathway to development of diabetes foot ulcers is repetitive daily activity stress on the plantar surface of the neuropathic foot. Studies suggest an association between different diabetic foot complications and physical activity. However, to the best of the authors knowledge the steps/day and sleep patterns of people with diabetic foot ulcers has yet to be investigated. This observational study aims to investigate the physical activity and sleep patterns of three groups of adults with type 2 diabetes and different foot complications Methods Participants with type 2 diabetes were recruited into three groups: 1. those with no reported foot complications (DNIL), 2. those with diagnosis of neuropathy (DPN) and 3. those with a neuropathic ulcer (DFU). Exclusion criteria included peripheral arterial disease and mobility aid use. Participants wore a SenseWear Pro 3 Armband continuously for 7 days and completed an Epworth Sleepiness Scale. The Armband is a validated automated measure of activity (walking steps, average Metabolic Equivalent Task (MET), physical activity (>3 METs) duration), energy expenditure(kJ) (total and physical activity (>3 METs)) and sleep (duration). Data on age, sex, BMI, diabetes duration and HbA1c were also collected. Results Sixty-Six (14 DNIL, 22 DPN and 30 DFU's participants were recruited; 71% males, mean age 61(±12) years, diabetes duration 13(±9) years, HbA1c 8.3(±2.8), BMI 32.6(±5.9), average METs 1.2(0.2). Significant differences were reported in mean(SD) steps/day (5,859(±2,381) in DNIL; 5,007(±3,349) in DPN and 3,271(±2,417) in DFU's and daily energy expenditure (10,868(±1,307)kJ in DNIL; 11,060(±1,916)kJ in DPN and 13,006(± 3,559) in DFU's(p <0.05). No significant differences were reported for average METs, physical activity duration or energy expenditure, sleep time or Epworth score (p>0.1). Conclusions Preliminary findings suggest people with diabetes are sedentary. Results indicate that patients with a diabetic foot ulcer work significantly less than those with neuropathy or nil complications and use significantly more energy to do so. Sleep Parameters showed no differences. Recruitment is still on going.

Gastrointestinal complications after kidney transplantation

The aim of the study was to evaluate gastrointestinal (GI) complications after kidney transplantation in the Finnish population. The adult patients included underwent kidney transplantation at Helsinki University Central Hospital in 1990-2000. Data on GI complications were collected from the Finnish Kidney Transplantation Registry, patient records and from questionnaires sent to patients. Helicobacter pylori IgG and IgA antibodies were measured from 500 patients before kidney transplantation and after a median 6.8-year follow up. Oesophagogastroduodenoscopy with biopsies was performed on 46 kidney transplantation patients suffering from gastroduodenal symptoms and 43 dyspeptic controls for studies of gastroduodenal cytomegalovirus (CMV) infection. Gallbladder ultrasound was performed on 304 patients after a median of 7.4 years post transplantation. Data from these 304 patients were also collected on serum lipids, body mass index and the use of statin medication. Severe GI complications occurred in 147 (10%) of 1515 kidney transplantations, 6% of them fatal after a median of 0.93 years. 51% of the complications occurred during the first post transplantation year, with highest incidence in gastroduodenal ulcers and complications of the colon. Patients with GI complications were older and had more delayed graft function and patients with polycystic kidney disease had more GI complications than the other patients. H.pylori seropositivity rate was 31% and this had no influence on graft or patient survival. 29% of the H.pylori seropositive patients seroreverted without eradication therapy. 74% of kidney transplantation patients had CMV specific matrix protein pp65 or delayed early protein p52 positive findings in the gastroduodenal mucosa, and 53% of the pp65 or p52 positive patients had gastroduodenal erosions without H.pylori findings. After the transplantation 165 (11%) patients developed gallstones. A biliary complication including 1 fatal cholecystitis developed in 15% of the patients with gallstones. 13 (0.9%) patients had pancreatitis. Colon perforations, 31% of them fatal, occurred in 16 (1%) patients. 13 (0.9%) developed a GI malignancy during the follow up. 2 H.pylori seropositive patients developed gastroduodenal malignancies during the follow up. In conclusion, severe GI complications usually occur early after kidney transplantation. Colon perforations are especially serious in kidney transplantation patients and colon diverticulosis and gallstones should be screened and treated before transplantation. When found, H.pylori infection should also be treated in these patients.

Helicobacter pylori: resistance and treatment results in Finland

Background: Helicobacter pylori infection is usually acquired in early childhood and is rarely resolved spontaneously. Eradication therapy is currently recommended virtually to all patients. While the first and second therapies are prescribed without knowing the antibiotic resistance of the bacteria, it is important to know the primary resistance in the population. Aim: This study evaluates the primary resistance of H. pylori among patients in primary health care throughout Finland, the efficacy of three eradication regimens, the symptomatic response to successful therapy, and the effect of smoking on gastric histology and humoral response in H. pylori-positive patients. Patients and methods: A total of 23 endoscopy referral centres located throughout Finland recruited 342 adult patients with positive rapid urease test results, who were referred to upper gastrointestinal endoscopy from primary health care. Gastric histology, H. pylori resistance and H. pylori serology were evaluated. The patients were randomized to receive a seven-day regimen, comprising 1) lansoprazole 30 mg b.d., amoxicillin 1 g b.d. and metronidazole 400 mg t.d. (LAM), 2) lansoprazole 30 mg b.d., amoxicillin 1 g b.d. and clarithromycin 500 mg b.d. (LAC) or 3) ranitidine bismuth citrate 400 mg b.d., metronidazole 400 mg t.d. and tetracycline 500 mg q.d. (RMT). The eradication results were assessed, using the 13C-urea breath test 4 weeks after therapy. The patients completed a symptom questionnaire before and a year after the therapy. Results: Primary resistance of H. pylori to metronidazole was 48% among women and 25% among men. In women, metronidazole resistance correlated with previous use of antibiotics for gynaecologic infections and alcohol consumption. Resistance rate to clarithromycin was only 2%. Intention-to-treat cure rates of LAM, LAC, and RMT were 78%, 91% and 81%. While in metronidazole-sensitive cases the cure rates with LAM, LAC and RMT were similar, in metronidazole resistance LAM and RMT were inferior to LAC (53%, 67% and 84%). Previous antibiotic therapies reduced the efficacy of LAC, to the level of RMT. Dyspeptic symptoms in the Gastrointestinal Symptoms Rating Scale (GSRS) were decreased by 30.5%. In logistic regression analysis, duodenal ulcer, gastric antral neutrophilic inflammation and age from 50 to 59 years independently predicted greater decrease in dyspeptic symptoms. In the gastric body, smokers had milder inflammation and less atrophy and in the antrum denser H. pylori load. Smokers also had lower IgG antibody titres against H. pylori and a smaller proportional decrease in antibodies after successful eradication. Smoking tripled the risk of duodenal ulcers. Conclusions: in Finland H. pylori resistance to clarithromycin is low, but metronidazole resistance among women is high making metronidazole-based therapies unfavourable. Thus, LAC is the best choice for first-line eradication therapy. The effect of eradication on dyspeptic symptoms was only modest. Smoking slows the progression of atrophy in the gastric body.

IgG4 Autoantibodies to DNA in Systemic Lupus erythematosus Patients

The presence of DNA-specific IgG4 antibodies was demonstrated in the sera of patients with systemic lupus erythematosus (SLE) by a microtiter solid-phase radioimmunoassay. A patient with distal inter-phalangeal swelling and extensive ulcers in the oral cavity, seronegative for anti-DNA antibodies of the IgG isotype, was found to have anti-DNA autoantibodies exclusively of the IgG4 subclass. These autoantibodies directed against the dsDNA conformation cross-reacted with chondroitin sulfate, dermatan sulfate and heparin.

Critical leg ischaemia with tissue loss : a challenge for the vascular surgeon

There is a widespread reporting habit of combining the outcomes for patients with rest pain (Fontaine III) and tissue loss (Fontaine IV) under the single category of critical leg ischaemia (CLI). This study focused on patients with ischaemic tissue loss treated with infrainguinal bypass surgery (IBS). All patients included in the study were treated at Helsinki University Central Hospital in 2000-2007. First, ulcer healing time after IBS and factors influencing healing time were prospectively assessed in 2 studies including 148 and 110 patients, respectively. Second,the results of redo IBS were retrospectively evaluated in 593 patients undergoing primary IBS for CLI with tissue loss . Third,long-term outcome were retrospectively analysed in 636 patients who underwent IBS for CLI with tissue loss . Fourth, the outcome of IBS was retrospectively compared with endovascular treatment (PTA) of the infrapopliteal arteries in 1023 CLI patients. Fifth, the influence multidrug resistant Pseudomans aeruginosa (MDR Pa) bacteria contamination in CLI patients treated with IBS was retropectively assessed. Sixty-four patients with positive MDR Pa -culture were matched with 64 MDR Pa - negative controls. Complete ulcer healing rate, including the ischemic ulcers and incisional wounds, was 40% at 6 months after IBS and 75% at one year. Diabetes was a risk factor for prolonged complete ulcer healing time. Ischaemic tissue lesions located in mid-and hindfoot healed poorly. At one year after IBS 50% of the patients were alive with salvaged leg and completely healed ulcers. The absence of gap between tertiary graft patency and leg salvage rates indicates the importance of a patent infrainguinal graft to save a leg with ischaemic tissue loss. Long-term survival for patients with ischaemic tissue loss was poor, 38% at 5 years. Only 30% of the patients were alive without amputation at 5 years. Several of the patient comorbidities increased independently the mortality risk; coronary artery disease, renal insufficiency, chronic obstructive lung disease and high age. When both PTA and bypass is feasible, infrapopliteal PTA as a first-line strategy is expected to achieve similar long-term results to bypass surgery in CLI when redo surgery is actively utilized. MDR Pa in a patient with CLI should be considered as a serious event with increased risk of early major amputation or death. Conclusion: Despite a successful infrainguinal bypass healing of the ischaemic ulcers and incisional wounds ulcer healing is a slow process especially in diabetics. Bypass surgery and PTA improve the outcome of the ischaemic leg but the mortality rate of the patients is high due to their severe comorbidities.

High-risk patients and high-risk grafts in infrainguinal bypass for critical limb ischaemia

The main purpose of revascularization procedures for critical limb ischaemia (CLI) is to preserve the leg and sustain the patient s ambulatory status. Other goals are ischaemic pain relief and healing of ischaemic ulcers. Patients with CLI are usually old and have several comorbidities affecting the outcome. Revascularization for CLI is meaningless unless both life and limb are preserved. Therefore, the knowledge of both patient- and bypass-related risk factors is of paramount importance in clinical decision-making, patient selection and resource allocation. The aim of this study was to identify patient- and graft-related predictors of impaired outcome after infrainguinal bypass for CLI. The purpose was to assess the outcome of high-risk patients undergoing infrainguinal bypass and to evaluate the usefulness of specific risk scoring methods. The results of bypasses in the absence of optimal vein graft material were also evaluated, and the feasibility of the new method of scaffolding suboptimal vein grafts was assessed. The results of this study showed that renal insufficiency - not only renal failure but also moderate impairment in renal function - seems to be a significant risk factor for both limb loss and death after infrainguinal bypass in patients with CLI. Low estimated GFR (PIENEMPI KUIN 30 ml/min/1.73 m2) is a strong independent marker of poor prognosis. Furthermore, estimated GFR is a more accurate predictor of survival and leg salvage after infrainguinal bypass in CLI patients than serum creatinine level alone. We also found out that the life expectancy of octogenarians with CLI is short. In this patient group endovascular revascularization is associated with a better outcome than bypass in terms of survival, leg salvage and amputation-free survival especially in presence of coronary artery disease. This study was the first one to demonstrate that Finnvasc and modified Prevent III risk scoring methods both predict the long-term outcome of patients undergoing both surgical and endovascular infrainguinal revascularization for CLI. Both risk scoring methods are easy to use and might be helpful in clinical practice as an aid in preoperative patient selection and decision-making. Similarly than in previous studies, we found out that a single-segment great saphenous vein graft is superior to any other autologous vein graft in terms of mid-term patency and leg salvage. However, if optimal vein graft is lacking, arm vein conduits are superior to prosthetic grafts especially in infrapopliteal bypasses for CLI. We studied also the new method of scaffolding suboptimal quality vein grafts and found out that this method may enable the use of vein grafts of compromised quality otherwise unsuitable for bypass grafting. The remarkable finding was that patients with the combination of high operative risk due to severe comorbidities and risk graft have extremely poor survival, suggesting that only relatively fit patients should undergo complex bypasses with risk grafts. The results of this study can be used in clinical practice as an aid in preoperative patient selection and decision-making. In the future, the need of vascular surgery will increase significantly as the elderly and diabetic population increases, which emphasises the importance of focusing on those patients that will gain benefit from infrainguinal bypass. Therefore, the individual risk of the patient, ambulatory status, outcome expectations, the risk of bypass procedure as well as technical factors such as the suitability of outflow anatomy and the available vein material should all be assessed and taken into consideration when deciding on the best revascularization strategy.

A histopathologic evaluation of gross lesions excised from commercially important North Altantic marine fishes

Histopathologic studies of lesions found in commercially important North Atlantic marine fishes are uncommon. As part of a comprehensive Northeast Fisheries Center program ("Ocean Pulse") to evaluate environmental and resource health on the U.S. Continental Shelf from Cape Hatteras to Nova Scotia, grossly visible lesions of the gills, integument, muscle, and viscera of primarily bottom-dwelling fishes were excised and examined using light microscopy. Several gadid and pleuronectid fishes accounted for most of the lesions observed. Most pathological examinations were incidental to samples taken for age and growth determination and evaluation of predator/prey relationships. Several gadids, with either gill, heart, or spleen lesions, were sampled more intensively. Gill lesions principally affected gadids and were caused by either microsporidans or an unidentified oocyte-like cell. The majority of gastrointestinal lesions consisted of encapsulated or encysted larval worms or microsporidan-induced cysts. Few heart lesions were found. Integumental lesioos included ulcers, lymphocystis, and trematode metacercariae. Liver lesions almost always consisted of encapsulated or encysted larval helminths. Necrotic granulomata were seen in muscle and microsporidan-induced granulomata in spleen. Although not numerous, histologically interesting lesions were noted in integument, heart, liver, spleen, and muscle of several fish species. Histologic study of tissues excised from a variety of demersal and pelagic fishes from the eastern North Atlantic (France, Germany, Spain) revealed assorted integumental, renal, hepatic, and splenic lesions. Small sample size and non-random sampling precluded obtaining a meaningful quantitative estimate of the prevalence of the observed lesions in the population at risk; however, a useful census has been made of the types of lesions present in commercially important marine fishes.

rhegf-Loaded Plga-Alginate Microspheres Enhance The Healing Of Full-Thickness Excisional Wounds In Diabetised Wistar Rats

[EN] Diabetic foot ulcers (DFUs) represent a major clinical challenge in the ageing population. To address this problem, rhEGF-loaded Poly-Lactic-co-Glycolic-Acid (PLGA)-Alginate microspheres (MS) were prepared by a modified w/o/w-doubleemulsion/ solvent evaporation method. Different formulations were evaluated with the aim of optimising MSs properties by adding NaCl to the surfactant solution and/or the solvent removal phase and adding alginate as a second polymer. The characterization of the developed MS showed that alginate incorporation increased the encapsulation efficiency (EE) and NaCl besides increasing the EE also became the particle surface smooth and regular. Once the MS were optimised, the target loading of rhEGF was increased to 1% (PLGA-Alginate MS), and particles were sterilised by gamma radiation to provide the correct dosage for in vivo studies. In vitro cell culture assays demonstrated that neither the microencapsulation nor the sterilisation process affected rhEGF bioactivity or rhEGF wound contraction. Finally, the MS were evaluated in vivo for treatment of the full-thickness wound model in diabetised Wistar rats. rhEGF MS treated animals showed a statistically significant decrease of the wound area by days 7 and 11, a complete re-epithelisation by day 11 and an earlier resolution of the inflammatory process. Overall, these findings demonstrate the promising potential of rhEGF-loaded MS (PLGA-Alginate MS) to promote faster and more effective wound healing, and suggest its possible application in DFU treatment.

Efeitos da aplicação tópica da S-Nitrosoglutationa no reparo tecidual de lesões cutâneas isquêmicas

A aplicação tópica do hidrogel Pluronic F-127 (poli(óxido de etileno)99-poli(óxido de propileno)65-poli(óxido de etileno)99, PEO99-PPO65-PEO99) contendo um doador de óxido nítrico, a S-nitrosoglutationa (GSNO) é conhecida por exercer efeitos benéficos no reparo tecidual cutâneo. O objetivo deste trabalho foi avaliar o efeito da aplicação tópica do hidrogel Pulronic F-127 contendo um doador de óxido nítrico no reparo tecidual de lesões isquêmicas. Ratos Wistar machos foram submetidos a duas lesões incisionais paralelas no dorso, a pele foi separada do tecido subjacente, as incisões foram suturadas e uma lesão excisional foi feita entre elas para criar uma condição isquêmica ao redor da lesão. Os animais foram separados em grupo controle, que recebeu a aplicação apenas do hidrogel sem doador de óxido nítrico e grupo tratado, que recebeu a aplicação do hidrogel contendo o doador de óxido nítrico. Os animais foram tratados por 7 dias consecutivos com uma aplicação diária dos hidrogéis. O grupo tratado apresentou taxas mais altas de contração e re-epitelização, menor quantidade de células inflamatórias, um aumento na densidade e organização de fibras colágenas e uma diminuição na neovascularização 14 dias após a lesão, comparado ao grupo controle. Esses resultados indicam que a aplicação tópica do gel doador de óxido nítrico é eficaz no tratamento de lesões isquêmicas em ratos, levando a uma melhora significativa na cicatrização. Consequentemente, a aplicação tópica de um hidrogel contendo doador de óxido nítrico poderá ter, futuramente, potencial para o tratamento terapêutico de úlceras venosas e decorrentes de diabetes.

Prevalência de doença celíaca em pacientes dispépticos sem diarreia atendidos na Disciplina de Gastroenterologia e Endoscopia Digestiva do Hospital Universitário Pedro Ernesto da UERJ

A Doença Celíaca (DC) é uma doença autoimune que afeta o intestino delgado de indivíduos geneticamente susceptíveis após contato com o glúten. Diversos estudos têm relatado aumento da prevalência ao longo dos anos. Objetivo: Determinar a prevalência de DC em pacientes adultos sem diarreia encaminhados à Disciplina de Gastroenterologia do HUPE da UERJ para serem submetidos a Endoscopia Digestiva Alta (EDA).Comparar os resultados do histopatológico das biópsias duodenais com os resultados sorológicos, utilizando o anticorpo antitransglutaminase tecidual IgA (ATGt IgA). Métodos: Pacientes que foram encaminhados ao nosso serviço para serem submetidos a EDA entre Julho de 2008 e Julho de 2010, com idade entre 18 e 85 anos foram aceitos no estudo. Critérios de exclusão foram cirrose, neoplasias do trato gastrointestinal, HIV, uso de imunossupressores e anticoagulantes, diarreia, hemorragia digestiva e DC. Coleta de sangue para pesquisa do anticorpo ATGt IgA (utilizando KIT ORGENTEC - Alemanha), avaliação endoscópica e exame histopatológico das biópsias de segunda porção duodenal foram feitos para cada paciente. Biópsias foram avaliadas de acordo com o critério de Marsh modificado. Resultados: Trezentos e noventa e nove pacientes consecutivos (112 homens, 287 mulheres), média de idade 49,616,4 anos, variando de 18-85 anos, sem diarreia, foram prospectivamente aceitos. Os sintomas clínicos mais prevalentes foram dor abdominal em 99,5%, pirose em 41,1%, plenitude pós prandial em 30,6%, náuseas e vômitos em 21,3%. Os achados endoscópicos foram: normais em 41,6%, lesões pépticas (esofagite, gastrite, duodenite e úlceras) em 41,6%, hérnia hiatal em 5,5%, pólipos gástricos em 3%, neoplasias em 1,3% e miscelânea em 7%. DC foi endoscopicamente diagnosticada em 13 pacientes (3,3%) com mucosa duodenal exibindo serrilhamento das pregas em 8 (2%), diminuição do pregueado em 2 (0,5%) e mucosa exibindo padrão nodular e mosaico em 3 (0,75%). Os achados histopatológicos de duodeno foram normais em 96,7%, duodenites inespecíficas em 2,7% e 3 pacientes (0,75%) confirmaram DC pelos critérios de Marsh modificado (IIIa, IIIb e IIIc). O anticorpo ATGt IgA foi positivo (>10 U/ml) em 1,3% (5/399). Conclusão: Este estudo mostrou que a prevalência de DC em pacientes dispépticos sem diarreia atendidos na Disciplina de Gastroenterologia e Endoscopia do HUPE/UERJ foi de 0,75% (1:133). A acurácia diagnóstica do anticorpo ATGt IgA é boa para pacientes com Marsh III e achados endoscópicos sugestivos. Nenhum dos pacientes tinha alterações Marsh I ou II. A EDA se mostrou um excelente método de triagem para definir os pacientes com graus mais acentuados de atrofia e que se beneficiariam de biópsia e sorologia para confirmação diagnóstica. Os resultados obtidos neste trabalho não justificam uma triagem rotineira de DC.

Prevenção da úlcera de pressão: resultados da ação educativa junto à equipe de enfermagem

Os pacientes hospitalizados, acamados ou restritos ao leito, apresentam uma gama de fatores de risco para o desenvolvimento das úlceras por pressão, diante disso, necessitam de uma assistência de enfermagem qualificada e eficaz na prevenção dessas lesões, a fim de evitar o desenvolvimento das mesmas. Desta forma, a pesquisa teve como objetivo investigar a influência da ação educativa junto à equipe de enfermagem das enfermarias de Clínica Médica na prevenção das úlceras por pressão. Tratou-se de um estudo quantitativo com delineamento descritivo com dispositivo de intervenção do tipo antes e depois, tendo como cenário as enfermarias de Clínica Médica de um hospital universitário na cidade do Rio de Janeiro. Os sujeitos foram os enfermeiros (n=15) e técnicos de enfermagem (n=18) da Clínica Médica e a unidade de medida do estudo foi o número de vezes que as ações de enfermagem, referentes à prevenção das úlceras por pressão e desempenhadas pelos sujeitos, foram observadas pela pesquisadora. Obtivemos 396 observações antes da ação educativa e 204 depois da ação educativa. A pesquisa apresentou três etapas: observação sistematizada antes da ação educativa, realização da ação educativa e observação sistematizada depois da ação educativa. Os resultados foram obtidos através da análise dos Check list antes e depois da ação educativa e constatamos, por meio de valores percentuais, melhoras significativas. A categoria sempre, considerada o valor ideal para todas as variáveis, apresentou aumento de 20 pontos percentuais entre as observações; a categoria frequentemente apresentou aumento de 07 pontos e a categoria raramente apresentou decréscimo de 27 pontos. Isso demonstra que a ação educativa atingiu o objetivo de sensibilizar a equipe de enfermagem quanto a prevenir as úlceras por pressão de forma qualificada. Concluímos que as úlceras por pressão continuam sendo um grande problema de saúde pública, merecendo atenção especial por parte da equipe de enfermagem. Acreditamos que a ação educativa é capaz de sensibilizar a equipe de enfermagem e motivar a transformação das ações e condutas, porém, ela é pontual e é apenas uma parte do processo educacional. Para alcançarmos a mudança comportamental e proporcionar uma assistência qualificada e eficiente aos pacientes em risco de desenvolver as úlceras por pressão, sugerimos o desenvolvimento de uma prática educativa contínua e permanente, capaz de manter a equipe de enfermagem em constante aperfeiçoamento.

The prevalence of diabetes-related complications and multimorbidity in the population with type 2 diabetes mellitus in the Basque Country

Background: Type 2 diabetes mellitus is associated with a diverse range of pathologies. The aim of the study was to determine the incidence of diabetes-related complications, the prevalence of coexistent chronic conditions and to report multimorbidity in people with type 2 diabetes living in the Basque Country. Methods: Administrative databases, in four cross sections (annually from 2007 to 2011) were consulted to analyse 149,015 individual records from patients aged >= 35 years with type 2 diabetes mellitus. The data observed were: age, sex, diabetes-related complications (annual rates of acute myocardial infarction, major amputations and avoidable hospitalisations), diabetes-related pathologies (prevalence of ischaemic heart disease, renal failure, stroke, heart failure, peripheral neuropathy, foot ulcers and diabetic retinopathy) and other unrelated pathologies (44 diseases). Results: The annual incidence for each condition progressively decreased during the four-year period: acute myocardial infarction (0.47 to 0.40%), major amputations (0.10 to 0.08%), and avoidable hospitalisations (5.85 to 5.5%). The prevalence for diabetes-related chronic pathologies was: ischaemic heart disease (11.5%), renal failure (8.4%), stroke (7.0%), heart failure (4.3%), peripheral neuropathy (1.3%), foot ulcers (2.0%) and diabetic retinopathy (7.2%). The prevalence of multimorbidity was 90.4%. The highest prevalence for other chronic conditions was 73.7% for hypertension, 13.8% for dyspepsia and 12.7% for anxiety. Conclusions: In the type 2 diabetes mellitus population living in the Basque Country, incidence rates of diabetes complications are not as high as in other places. However, they present a high prevalence of diabetes related and unrelated diseases. Multimorbidity is very common in this group, and is a factor to be taken into account to ensure correct clinical management.
