Gender differences in cancer patients with acute venous thromboembolism.

BACKGROUND: The outcome of cancer patients with acute venous thromboembolism (VTE) may differ according to gender. METHODS: We used the RIETE database to compare the rate of VTE (pulmonary embolism [PE] or deep vein thrombosis [DVT]) recurrences), major bleeding and mortality during the course of anticoagulation, according to gender. RESULTS: As of August 2014, 11,055 patients with active cancer were enrolled in RIETE, of whom 5,104 (46%) were women. During the course of anticoagulation (mean: 142 days), 505 patients developed recurrent VTE, 429 bled and 2730 died. Compared with men, women had a significantly lower rate of fatal bleeding (risk ratio [RR]: 0.69; 95% CI: 0.47-0.99) and death (RR: 0.90; 95% CI: 0.83-0.97), and a non-significantly lower rate of PE recurrences (RR 0.83; 95% CI: 0.65-1.06) and major bleeding (RR: 0.89; 95% CI: 0.74-1.08). CONCLUSIONS: During the course of anticoagulation, cancer women with VTE had a better outcome than men.

Association between smoking and recurrence of venous thromboembolism and bleeding in elderly patients with past acute venous thromboembolism.

BACKGROUND: While the association between smoking and arterial cardiovascular events has been well established, the association between smoking and venous thromboembolism (VTE) remains controversial. OBJECTIVES: To assess the association between smoking and the risk of recurrent VTE and bleeding in patients who have experienced acute VTE. PATIENTS/METHODS: This study is part of a prospective Swiss multicenter cohort that included patients aged ≥65years with acute VTE. Three groups were defined according to smoking status: never, former and current smokers. The primary outcome was the time to a first symptomatic, objectively confirmed VTE recurrence. Secondary outcomes were the time to a first major and clinically relevant non-major bleeding. Associations between smoking status and outcomes were analysed using proportional hazard models for the subdistribution of a competing risk of death. RESULTS: Among 988 analysed patients, 509 (52%) had never smoked, 403 (41%) were former smokers, and 76 (8%) current smokers. After a median follow-up of 29.6months, we observed a VTE recurrence rate of 4.9 (95% confidence interval [CI] 3.7-6.4) per 100 patient-years for never smokers, 6.6 (95% CI 5.1-8.6) for former smokers, and 5.2 (95% CI 2.6-10.5) for current smokers. Compared to never smokers, we found no association between current smoking and VTE recurrence (adjusted sub-hazard ratio [SHR] 1.05, 95% CI 0.49-2.28), major bleeding (adjusted SHR 0.59, 95% CI 0.25-1.39), and clinically relevant non-major bleeding (adjusted SHR 1.21, 95% CI 0.73-2.02). CONCLUSIONS: In this multicentre prospective cohort study, we found no association between smoking status and VTE recurrence or bleeding in elderly patients with VTE.

Cranial computed tomography findings in patients admitted to the emergency unit of Hospital Universitário Cajuru

Objective To identify and analyze the prevalence of cranial computed tomography findings in patients admitted to the emergency unit of Hospital Universitário Cajuru. Materials and Methods Cross-sectional study analyzing 200 consecutive non contrast-enhanced cranial computed tomography reports of patients admitted to the emergency unit of Hospital Universitário Cajuru. Results Alterations were observed in 76.5% of the patients. Among them, the following findings were most frequently observed: extracranial soft tissue swelling (22%), bone fracture (16.5%), subarachnoid hemorrhage (15%), nonspecific hypodensity (14.5%), paranasal sinuses opacification (11.5%), diffuse cerebral edema (10.5%), subdural hematoma (9.5%), cerebral contusion (8.5%), hydrocephalus (8%), retractable hypodensity /gliosis/ encephalomalacia (8%). Conclusion The authors recognize that the most common findings in emergency departments reported in the literature are similar to the ones described in the present study. This information is important for professionals to recognize the main changes to be identified at cranial computed tomography, and for future planning and hospital screening aiming at achieving efficiency and improvement in services.

An ABC for decision making

The present study was aimed at proposing a systematic evaluation of cranial computed tomography, identifying the main aspects to be analyzed in order to facilitate the decision making process regarding diagnosis and management in emergency settings. The present descriptive study comprised a literature review at the following databases: Access Medicine and Access Emergency Medicine (McGraw- Hill Education); British Medical Journal Evidence Center; UptoDate; Bireme; PubMed; Lilacs; SciELO; ProQuest; Micromedex (Thomson Reuters); Embase. Once the literature review was completed, the authors identified the main diseases with tomographic repercussions and proposed the present system to evaluate cranial computed tomography images. An easy-to-memorize ABC system will facilitate the decision making in emergency settings, as it covers the main diseases encountered by intensivists and emergency physicians, and provides a sequential guidance about anatomical structures to be investigated as well as their respective alterations.

Computed tomography angiography in patients with active gastrointestinal bleeding

Abstract Gastrointestinal bleeding represents a common medical emergency, with considerable morbidity and mortality rates, and a prompt diagnosis is essential for a better prognosis. In such a context, endoscopy is the main diagnostic tool; however, in cases where the gastrointestinal hemorrhage is massive, the exact bleeding site might go undetected. In addition, a trained professional is not always present to perform the procedure. In an emergency setting, optical colonoscopy presents limitations connected with the absence of bowel preparation, so most of the small bowel cannot be assessed. Scintigraphy cannot accurately demonstrate the anatomic location of the bleeding and is not available at emergency settings. The use of capsule endoscopy is inappropriate in the acute setting, particularly in the emergency department at night, and is a highly expensive method. Digital angiography, despite its high sensitivity, is invasive, presents catheterization-related risks, in addition to its low availability at emergency settings. On the other hand, computed tomography angiography is fast, widely available and minimally invasive, emerging as a promising method in the diagnostic algorithm of these patients, being capable of determining the location and cause of bleeding with high accuracy. Based on a critical literature review and on their own experience, the authors propose a computed tomography angiography protocol to assess the patient with gastrointestinal bleeding.

Influència de l'educació envers prevenció d'úlceres per pressió en els coneixements dels professionals de l'equip d'infermeria i en la prevalença

Les úlceres per pressió són considerades com una de les cinc causes més comunes de dany al pacient. El 95% de les lesions, són evitables i els membres de l’equip d’infermeria són responsables de la seva prevenció. Varis estudis demostren un dèficit de coneixement dels professionals de l’equip d’infermeria envers prevenció d’UPP.En el següent projecte d’estudi, de disseny experimental longitudinal ambispectiu, es proposa avaluar l’eficàcia d’una intervenció educativa enfocada en la prevenció d’UPP i dirigida a l’equip d’infermeria per la disminució de la incidència d’UPPEl projecte consta de 6 fases. Una primera en la que es determinarà, mitjançant la revisió de les històries clíniques, la prevalença d’UPP. Posteriorment i amb l’aplicació d’un qüestionari, es valoraran els coneixements d’infermeria abans (fase 2) i després (fase 4) de la realització d’un programa educatiu (fase 3). Durant la fase 5 i amb l’ajuda d’una graella d’observació, es determinarà la incidència d’UPP durant un any des de l’aplicació del programa educatiu. A la fase 6 i passat més d’un any, es tornaran a avaluar els coneixements de l’equip d’infermeria

Resultados del tratamiento de la hemorragia digestiva alta por varices esofagogástricas

Introducción: el tratamiento de la hemorragia digestiva alta por rotura de varices esofágicas y/o gástricas en pacientes con cirrosis hepática debe estar dirigido al control inicial de la hemorragia sin alterar más una función hepática ya deteriorada , y a la prevención de la recidiva hemorrágica precoz. Métodos endoscópicos, farmacológicos y quirúrgicos forman el conjunto de alternativas terapéuticas. Material y métodos: estudio prospectivo de los resultados obtenidos tras el seguimiento de 90 episodios hemorrágicos de un total de 54 pacientes, 35 hombres y 19 mujeres, con una edad media de 58 años (32-77), sobre los que se aplicó un protocolo terapéutico de la hemorragia aguda secundaria a la hipertensión portal, durante un periodo de 22 meses. La clasificación según Child-Pugh al ingreso fue 57% Child A, 34% Child B y 9% Child C. Resultados: la estancia media hospitalaria fue de 9 días (2-50). De los 90 episodios hemorrágicos, se registraron 15 recidivas hemorrágicas precoces (16,7%). Murieron 12 pacientes (mortalidad del 22,2% por pacientes y del 13,4% por episodios hemorrágicos). Se realizaron 12 intervenciones de urgencias por persistencia de la hemorragia. El 41% de los pacientes reingresaron por recidiva de la hemorragia al menos una vez durante el periodo de seguimiento. Conclusiones: el tratamiento de la hemorragia digestiva alta por varices esófago-gástricas con cirrosis hepática, requiere un conjunto de diferentes tratamientos para obtener la máxima eficacia en el episodio hemorrágico agudo y poder abarcar todas las posibles repercusiones a posteriori; dicho tratamiento debería ser realizado en un centro hospitalario que disponga de material y personal especializado en esta patología. En nuestra experiencia, la cirugía de urgencias, como tratamiento de rescate de la hemorragia persistente o recidivante a corto plazo, sólo tendría lugar en algunos pacientes con una buena función hepática dada su alta morbi/mortalidad

Perfuração gástrica secundária a tricobezoar gigante: descrição de caso e revisão da literatura

Gastric bezoars are impactations offoreign material in lhe stomach. When they are caused by hail; they are named tricho- bezoars. The complications oftrichobezoars are very rare. In this papel; we describe a case of a 16-year-old girl that had a previous history oftricophagia, and had an acute abdominal pain with a pneumoperitoneum in the abdomen radiography. An operation was performed and a gastric perforation was founded associated with a giant trichobezoa7: The trichobezoar was removed by traction through a gastrostomy which was performed in order to remove lhe trichobezoa7: Some fragments of the ulcer were obtained to histological study. The gastrostomy was treated by a gastrorraphy confection. In lhe post- operative period a left subfrenic abscess was revealed and has been drained by laparatomy 15 days after the fisrt operation. After the second surgical procedure the patient had a good evolution, and left the hospital in good health conditions.

Hemosuccus pancreaticus: causa rara de hemorragia digestiva maciça

Hemosuccus pancreaticus is a unusual syndrome manifested by hemorrhage into the pancreatic duct and by blood loss through the ampulla of Vater: It may be caused by tumors, arteriovenous malformation, pancreatic lithiasis, aneurism rupture from adjacent vessels, or erosion of pancreatic and peripancreatic vessels due to chronic pancreatitis. The authors describe a case of massive and recurrent gastrointestinal upper hemorrhage in a 26-year-old man without known risk factors for pancreatitis. This man underwent urgent surgery due to gastrointestinal bleeding during the ínvestigation. During the procedure, blood was found in the intestinal lumen and a tumor in the head of pancreas with two centimeters of diameter: A gastroduodenopancreatectomy was performed. Histological study showed chronic pancreatitis with a fistula from the pancreatic vessels to the Wirsung duct. The patient was discharged without postoperative complications and after months, remains assymptomatic.

Síndrome de Zollinger-Ellison

The authors report a 49 years old, female patient who have been operated on several times (antrectomy with Billroth II reconstruction, partial gastrectomy with troncular vagotomy and total gastrectomy) in the last 5 years for recurrent ulcer disease. Three months ago, an abdomen ultra sound was done showing multiples images that suggested liver metastasis, which was confirmed by CT and RM. Two months ago, one new abdomen CT specifically to pancreas was done showing an expansive process in pancreas. Serial gastrine was 1532 pg/ml at the time (reference - until 115) and among clinical history and images exams Zollinger-Ellison Syndrome was suggested, a rare disease case.

Pneumatose intestinal

Pneumatosis Intestinalis (PI) is the presence of gas-filled cysts within the wall of the gastrointestinal tract (GIT). It is a clinical and/or radiological sign associated with a wide spectrum of diseases, so that it has a variable clinical significance. Probably, its prevalence is increasing. The nature of the diseases causing PI is been modifying in last decades. Peptic ulcers were its main cause in the past. Nowadays, probably, immunosuppressive conditions and states of increased permeability of the GIT mucosa (AIDS, transplanted patients or in chemotherapy, etc) are more common causes. PI can be shown on simple abdominal roentgenograms and computed tomographic scans obtained with lung windows. Its diagnosis include definition of the cause in addition to its presence. The treatment should be directed to the cause of the PI, fluctuating from expectant to emergency laparotomy. The present report is a contribution to the limited literature experience in this topic and calls attention to the importance of recognizing PI and its clinical significance in order to define the right conduct.

Cisto de duplicação gástrica com parênquima pancreático ectópico em adulto assintomático

The authors describe a rare case of a gastric duplication cyst in a 55-year-old man. The past history revealed that the patient was treated one year before for gastroduodenal ulcer. The cyst was discovered incidentally at upper gastrointestinal endoscopy. Biopsies showed inflammation without evidence of tumor. On abdominal ultrasonography and CT scan, a left upper quadrant mass was noted. At laparotomy, a mass measuring 6,0 cm in contact with the stomach was excised. Histopathology showed a gastric duplication cyst containing pancreatic mucosa.
