Colonic vasculitis in a woman with end-stage kidney disease and HIV infection.

We present the case of a 57-year-old female with bloody diarrhea, fever and abdominal pain. Her medical history included human immunodeficiency virus (HIV) infection with an undetectable viral load and end-stage kidney disease secondary to HIV on dialysis. At admission, she had a painful abdomen, no skin lesions and bloody stools in the rectal examination. Laboratory findings included a white blood cell count of 12,900 x 103 cells/µl, CD4 counts of 243 cells/µl and C-reactive protein of 24.5 mg/dl. Serologies, cytomegalovirus and PCR SARS-CoV-2 were negative.

Epstein-Barr virus-positive mucocutaneous ulcer mimicking sigmoid colon adenocarcinoma.

Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) belongs to a spectrum of EBV-associated lymphoproliferative disease. We present the case of an 89-year-old female with seronegative polyarthritis treated for several years with methotrexate (12.5 mg weekly). She also had asthenia, anorexia and a positive fecal immunohistochemical test. In view of the above, a colonoscopy was performed that revealed a polypoid mass with a malignant appearance in the sigmoid colon, which prevented the passage of the endoscope and was suggestive of colonic adenocarcinoma (CAC).

Herpetic esophagitis in immunocompentent host: cases report.

BACKGROUND: Herpetic esophagitis (EH) usually affects those who are immunocompromised and is uncommon in immunocompetent patients. In these cases, EH may occasionally present as an acute and self-limited illness. Such cases are rare and only a few have beenreported and limited published reviews exist making the benefits of antiviral therapy in immunocompetent patients unknown. CASE PRESENTATION: We report four cases of young patients who presented dysphagia, odynophagia and epigastric pain. Endoscopic findings revealed lesions in the distal esophagus and histopathological changes compatible with herpes virus infection confirmed by viral DNA in every case. After treatment, every patient showed significant improvement and tolerated oral intake after discharge. CONCLUSIONS: In this publication, we present four immunocompetent patients with EH, without relevant alterations in laboratory workup and with negative HIV status. This disease is infrequent in patients with such characteristics and there are few cases published. In order to better understand this pathology, we present the symptoms, the endoscopic alterations and the clinical evolution with treatment. In our series, 50% of patients had serology compatible with acute HVS type 1 infection, 25% had a subacute infection pattern (IgM and IgG positive antibodies) and in another 25% of patients, serology was not done. No patient presented leukocyte alterations, while all patients presented with anatomopathological findings compatible with acute herpetic esophagitis and responded to acyclovir therapy.

Effective treatment of autoimmune hepatitis-primary biliary cholangitis overlap syndrome with obeticholic acid.

There is no consensus treatment for patients with autoimmune hepatitis (AIH) - primary biliary cholangitis (PBC) overlap syndrome who are not responding to conventional therapy. We present a case of a 43-yr-old woman with AIH-PBC overlap syndrome treated with obeticholic acid (OCA). The patient showed a reduction in liver enzymes and no fibrosis progression during 15 months of follow up.

What Ibero-American hospitals do when things go wrong? A cross-sectional international study.

OBJECTIVE: To know what hospital managers and safety leaders in Ibero-American countries are doing to respond effectively to the occurrence of adverse events (AEs) with serious consequences for patients. DESIGN: Cross-sectional international study. SETTING: Public and private hospitals in Ibero-American countries (Argentina, Brazil, Chile, Colombia, Mexico, Peru, Portugal and Spain). PARTICIPANTS: A convenience sample of hospital managers and safety leaders from eight Ibero-American countries. A minimum of 25 managers/leaders from each country were surveyed. INTERVENTIONS: A selection of 37 actions for the effective management of AEs was explored. These were related to the safety culture, existence of a crisis plan, communication and transparency processes with the patients and their families, attention to second victims and institutional communication. MAIN OUTCOME MEASURE: Degree of implementation of the actions studied. RESULTS: A total of 190 managers/leaders from 126 (66.3%) public hospitals and 64 (33.7%) private hospitals participated. Reporting systems, in-depth analysis of incidents and non-punitive approaches were the most implemented interventions, while patient information and care for second victims after an AE were the least frequent interventions. CONCLUSIONS: The majority of these hospitals have not protocolized how to act after an AE. For this reason, it is urgent to develop and apply a strategic action plan to respond to this imperative safety challenge. This is the first study to identify areas of work and future research questions in Ibero-American countries.

Características y supervivencia del carcinoma hepatocelular en hígado no cirrótico / Characteristics and survival of hepatocellular carcinoma in non-cirrhotic liver

Introducción: las características, cribado, y supervivencia del carcinoma hepatocelular (CHC) en pacientes sin cirrosis están menos definidas. Pacientes y métodos: se recogieron retrospectivamente (enero 2004-octubre 2018) los pacientes con CHC diagnosticados citohistológicamente sin cirrosis. Analizamos sus características, tratamiento y supervivencia. Resultados: de los 332 pacientes con CHC, 25 cumplían los criterios de inclusión (7,5%). Varones: 76%. Mediana de edad: 69,9 años. El virus de la hepatitis B (VHB) fue el principal agente etiológico de hepatopatía: 32%, seguido de la esteatohepatitis no alcohólica (EHNA): 20%. La fibrosis fue leve (0-1) en el 44%. El nódulo se descubrió por ecografía de seguimiento en el 32%, en el 60% fue casual, y 8% por síntomas. El estadio de Barcelona Clinic Liver Cancer (BCLC) fue 0 en 4%, A 88%, B 4%, y C 4%. El tratamiento inicial mayoritario fue la resección quirúrgica (76%), 8% rechazaron tratamiento, y se realizó etanolización, quimioembolización, sorafenib y tratamiento sintomático en el 4% para cada uno. El 21% de los pacientes operados presentó complicaciones, la mitad severas. La mediana de seguimiento fue 22,2 (2,9-150,6) meses, con remisión en el 56%. Mediana de supervivencia global: 57,4 +/- 29,8 meses. Supervivencia acumulada: 84% al año, 61,6% a los 3 años y 47,9% a los 5 años. Conclusión: el 7,5% de los CHC se desarrollaron sin cirrosis. El grado de fibrosis fue leve en casi la mitad. El VHB fue la causa principal, seguida de EHNA. El estadio de BCLC principal al diagnóstico fue el precoz. La cirugía fue el tratamiento más habitual. La supervivencia a los 5 años fue cercana al 50%

Introduction: the characteristics, screening, and survival of hepatocellular carcinoma (HCC) for patients without cirrhosis have not been fully studied. Methods: A retrospective cohort study was performed in non-cirrhotic patients with histological HCC, between January 2004 and October 2018. Their characteristics, treatment, follow-up and overall survival were described. Results: 25 of the 332 patients with HCC met the inclusion criteria (7.5%), 76% were males and the median age was 69.9 years. The main etiology of liver disease was the hepatitis B virus (HBV) (32%), followed by non-alcoholic steatohepatitis (NASH) (20%). Liver fibrosis was mild (0-1) in 44% of cases. The nodule was diagnosed by ultrasonography in 32% of cases, 60% were found incidentally and 8% due to clinical symptoms. The Barcelona Clinic Liver Cancer (BCLC) staging was 0 in 4% of cases, A in 88%, B in 4% and C in 4%. The main initial treatment was surgical resection (76%) and 8% refused to be treated. Percutaneous ethanol injection, chemoembolization, sorafenib and palliative care were each performed in 4% of cases. There were some complications in 21% of patients treated with surgery, half of them were severe. The median follow-up was 22.2 (2.9-150.6) months and 56% were in remission and the median overall survival was 57.4 +/- 29.8 months. The overall cumulative survival at 1, 3 and 5 years was 84%, 61.6% and 47.9%, respectively. Conclusion: 7.5% of HCC presented without cirrhosis and almost half of patients had mild fibrosis. HBV was the main cause of HCC, followed by NASH. The most frequent BCLC stage at diagnosis was early stage and surgery was the most common treatment. Overall cumulative survival at 5 years was almost 50%

Tipos de estudios epidemiológicos en revistas biomédicas peruanas / Type of epidemiologycal studies in peruvian biomedical journals

Las publicaciones biomédicas se han convertido en tema de investigación en años recientes. para tal efecto se han diseñado esquemas para su clasificación y se han revisado su diseño. En este estudio se analizan 1989 artículos publicados entre 1979 y 1983 en 5 revistas seleccionadas en lo que concierne a los tipos de estudios reportados (con énfasis en los epidemiológicos) y al uso de métodos estadísticos. Se encontró que la mayoría de artículos son de revisión de información (852 - 42.8%) y que de aquellos epidemiológicos casis todos son descriptivos (274 - 92.8%); asismismo el 83.4% de los 294 artículos epidemiológicos no mencionaron ningún método estadístico. Podemos inferir que la investigación epidemiológica en el Perú se orienta fundamental en la descripción de fenómeno más que en el análisis de los mismos
