[Use of the Scottish and Newcastle Anti-Emetic Pretreatment (SNAP) scheme in recovery from massive overdose of acetaminophen poisoning with acute liver failure - Case report]. / Uso del esquema Scottish and Newcastle Anti-Emetic Pretreatment (SNAP) en la recuperación de una intoxicación por sobredosis masiva de acetaminofén (paracetamol) con injuria hep ática aguda - Reporte de caso.

Acetaminophen is a drug widely used in the world and easily accessible due to its antipyretic, analgesics characteristics, among others (1); however, exposure to toxic doses causes organic damage and even death. We present the case of an 18-year-old female patient who ingested 40 grams of acetaminophen and developed severe liver dysfunction, being treated with N-acetylcysteine (NAC) antidotal therapy according to the simplified scheme: Scottish and Newcastle Anti-emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presenting improvement in the clinical course and decrease in liver profiles, coagulation disorder, INR and resolution of the condition.

Adverse reactions to antituberculosis drugs presenting as DRESS syndrome and acute liver failure.

Drug induced liver injury (DILI) can be can be triggered by many medications including antituberculosis drugs. We present the case of a 37-year-old woman with a smear- positive pulmonary tuberculosis who started treatment with first-line antituberculosis drugs and 4 weeks later presented jaundice, somnolence and a morbilliform generalized rash with progressive neurologic deterioration which had a fatal outcome. Antituberculosis drugs can cause DILI in 2 to 28% of patients and drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) in 1.2%. Acute liver failure (ALF) can occur in 35% of patients with DILI with an overall mortality of 9.7%. If the ALF is unresponsive to medical treatment, liver transplantation has shown promising results and can avoid progression of complications. DILI can be a serious medical condition in patients receiving antituberculosis drugs. If ALF develops and is unresponsive to medical treatment, liver transplantation should be considered as the treatment of choice.

La injuria hepática inducida por fármacos (IHIF) puede ser desencadenado por varios medicamentos incluyendo fármacos anti tuberculosos. Presentamos el caso de una paciente mujer de 37 años con un frotis positivo para tuberculosis pulmonar quien inició tratamiento de primera línea y 4 semanas después, presentó ictericia, somnolencia y un exantema generalizado de tipo morbiliforme con deterioro neurológico progresivo y un desenlace fatal. Los fármacos anti tuberculosos pueden producir injuria inducida por fármacos en 2 a 28% de pacientes y síndrome de DRESS (reacción de sensibilidad a medicamentos con eosinofilia y síntomas sistémicos) en 1,2%. La falla hepática aguda (FHA) en pacientes con injuria hepática inducida por fármacos, puede presentarse en un 35% con una mortalidad del 9,7%. Si la FHA no responde a tratamiento médico, el trasplante hepático ha mostrado resultados positivos y evita la progresión de complicaciones. La IHIF puede ser una condición médica grave en pacientes que reciben medicamentos antituberculosos. Si se desencadena una FHA y no responde a tratamiento médico, debe considerarse con urgencia la posibilidad de trasplante hepático.

[Use of cyanoacrylate as a treatment of gastric varices in a public hospital in Lima - Peru]. / Uso de cianoacrilato como tratamiento de várices gástricas en un hospitalp úblico nivel III en Lima - Per ú.

OBJECTIVE: To evaluate the therapeutic success of endoscopic therapy with N-butyl-2-cyanoacrylate and to determine the re- bleeding and mortality rates. MATERIALS AND METHODS: Prospective analytical observational study of 47 cases of patients with gastric varices who were treated with N-butyl-2-cyanoacrylate, using a 1: 1 mixture with lipiodol between 2013 and 2017 in a level III public hospital in Lima - Peru. The therapeutic indication was active hemorrhage, primary or secondary prophylaxis. RESULTS: Of the 47 patients, 5 (10.6%) had active hemorrhage, control was obtained in all cases, 24 (51.1%) had stigmas of recent bleeding during endoscopy. Secondary prophylaxis was performed in 16 (34%) patients and primary prophylaxis in 2 (4.7%). 59.6% required a single session with a total volume of cyanoacrylate (ml / patient) of 1.28 ± 0.44. The endoscopic finding was GOV-2 in 78.7% of the cases, IGV-1 in 12.8% and GOV-1 in 8.5%. Seven patients (14.8%) presented late re- bleeding, with successful new therapy in 6 of them, one dying due to therapy failure. Of the six (12.76%) patients who died in total, 5 (83.3%) were due to other causes. No adverse events related to the therapy were reported. No adverse events were reported. Variceal obturation was observed in 28 (59.5%) patients. CONCLUSIONS: Endoscopic management of gastric varices with cyanoacrylate is a safe and effective treatment, with low recurrence and mortality rates.

Histoplasmosis-induced ileal perforation in a patient with acquired immune deficiency syndrome: Case report.

Intestinal involvement with disseminated histoplasmosis is common in some populations infected with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), especially in those who come from tropical zones. We report the case of a 29-year-old male patient, from a tropical zone, with HIV infection and a CD4 value less than 50 cells/mm3, with a history of abdominal pain, fever, diarrhea, and weight loss. On presentation, he was pale, sweaty, and had abdominal rebound tenderness. Laboratory findings demonstrated microcitic hipocromic anemia, azoemia, and hypoalbuminemia. Abdominal-X-rays revealed pneumoperitoneum and air fluid levels. He underwent surgery, and a 1-cm perforation proximal to ileocecal valve was found. A resection and an ileostomy were performed. Histopathology identified caseating granulomas with yeast, compatible with histoplasmosis. He was treated with anfotericin B plus itraconazol with clinical improvement.

Introducción: Una condición de alta mortalidad a corto plazo en el cirrótico es la Insuficiencia hepática crónica reagudizada (ACLF por sus siglas en inglés), caracterizada por la falla de órgano(s) y precedida habitualmente por una descompensación aguda (DA). Objetivo: Determinar la frecuencia, el perfil clínico y la mortalidad en los cirróticos hospitalizados con ACLF. Materiales y métodos: Estudio analítico observacional realizado de julio 2016 a junio 2017. Se estableció la condición de ACLF según los criterios del estudio CANONIC. Resultados: Se reclutaron 118 pacientes cirróticos, 34 (28,8%) de los cuales presentaron ACLF, con grado 1: 14 (41%), grado 2: 16 (47%) y grado 3: 4 (12%) pacientes. La edad promedio fue 61,5 años; siendo la etiología más frecuente el alcoholismo en 18 pacientes (53%) y la mayoría no tenían historia previa de DA (64,7%). Los factores precipitantes más frecuentes fueron: la hemorragia digestiva (41%) y las infecciones (29,4%). Los grupos con y sin ACLF tuvieron una diferencia estadísticamente significativa en el puntaje Child-Turcotte-Pugh (CTP) (11,4 ± 1,8 vs 8,69 ± 2,04; p<0,0001), puntaje MELD (26,4 ± 8,1 vs 14,4 ± 4,6; p<0,0001), leucocitos (11 809,7 ± 6906,3/mm3 vs 8434,01 ± 5434,9/mm3; p: 0,006) y mortalidad a 28 días (76,5% vs 21,4%; p<0,0001), con un riesgo relativo (RR) de 3,5. Conclusiones: La frecuencia de ACLF fue 28,8%, similar a la del estudio CANONIC (30,9%). El principal factor precipitante fue la hemorragia digestiva. Los puntajes CTP, MELD y leucocitos fueron más altos en el grupo con ACLF, observándose una mortalidad a 28 días de 76,5% (3,5 veces mayor que en los pacientes sin ACLF).

Introduction: A condition of high short-term mortality in the cirrhotic patient is Acute-on-Chronic Liver Failure (ACLF), characterized by organ failure (s) and usually preceded by acute decompensation (AD). Objective: To determine the frequency, clinical profile, and mortality in cirrhotic patients hospitalized with ACLF. Materials and methods: This is an observational analytical study conducted from July 2016 to June 2017. We established the ACLF condition through the criteria of the CANONIC study. Results: The study population was 118 patients, of whom 34 (28.8%) presented ACLF, 14 (41%) were Grade 1, 16 (47%) Grade 2 and 4 (11.9%) Grade 3. The average age was 61.5 years old, alcoholism being the most frequent etiology with 18 patients (53%) and mostly without episodes of AD (64.7%). The most frequent precipitating factors were: Digestive hemorrhage (41%) and infections (29.4%). The groups with and without ACLF were statistically significant in the Child-Turcot- Pugh score (CTP) (11.4 ± 1.8 vs. 8.69 ± 2.04; p < 0.0001), MELD score (26.4 ± 8.1 vs. 14.4 ± 4.6; p < 0.0001), leukocytes (11,809.7 +/- 6,906.3 per mm3 vs. 8,434.01 ± 5,434.9 per mm3; p: 0.006) and 28-day mortality (76.5% vs. 21.4%, p < 0.0001), with a relative risk (RR) of 3.5. Conclusions: The frecuency of ACLF was 28.8%, similar to that of the CANONIC study (30.9%). The digestive hemorrhage being the main precipitating factor. The CTP, MELD and leukocyte scores were highest in this group. Mortality in patients with ACLF was 3.5 times more frequent than in patients without ACLF.

[Familiar adenomatous polyposis: report of 2 cases]. / Poliposis adenomatosa familiar: a propósito de 2 casos.

Familial Adenomatous polyposis (FAP) it is based on an autosomal dominant mutation which results in loss of function of theAPC tumor suppressor gene. On the other hand, Gardner syndrome is a type of FAP and is characterized for multiple colonic adenomatous polyps and extracolonic abnormalities as desmoid tumors, osteomas, lipomas, dental abnormalities, dermoid cysts and duodenal adenomas. This report aims to present two patients with FAP: The first one is a patient who presented with osteomas and hematochezia, being diagnosed with Gardner Syndrome after the colonoscopy. The second patient has a family history of colon cancer, who is diagnosed with FAP with tubular adenocarcinoma. We decide to report both cases due to the absence of previous reports in Peru.

[Validation of the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding in a third level general hospital]. / Validación del score de Rockall en pacientes adultos mayores con hemorragia digestiva alta no variceal en un hospital general de tercer nivel.

OBJECTIVE: To validate the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding, in terms of mortality and recurrent bleeding at 30 days follow-up. MATERIAL AND METHODS: Patients older than 60 year-old, with non variceal upper gastrointestinal bleeding demonstrated by endoscopy, who were attended in a third level general hospital from June 2009 to June 2013, were included. Data was analyzed with the ROC (Receiver Operating Characteristic) curve. The area under curve was obtained to assess the Rockall score. RESULTS: One hundred ninety patients were included, 64.2% were males, with an average age of 74 years old. Overall mortality was 16.8% and respiratory failure with second bleeding episode was the most common cause of death (34.3% and 31.3% respectively). 5.52% of patients presented a second bleeding episode. A transfusion of more than 2 blood-packs was needed in the 24.7% of the patients. The area under ROC curve using the Rockall score was 0,76 (IC: 0.68-0.84) for mortality risk, 0.71 (IC: 0.55-0.88) for the risk of rebleeding and 0.66 (IC: 0.58-0.74) for needing a more than 2 blood-packs transfusion. CONCLUSIONS: Rockall score is a good predictor for mortality and rebleeding during the 30 day-period after a non-variceal bleeding episode in elderly patients. The best sensibility and specificity was obtained with the scores of 5 and 6, respectively.

OBJECTIVE: To determine whether erradication of Helicobacter pylori (HP) infection from gastric mucosae is associated with changes in symptoms severity and satisfaction degree in patients with non-ulcer dyspepsia (NUD). METHODS: Prospective cohort study in patients with NUD and HP infection that were evaluated for six months following treatment, made up of 70 HP Negative patients in whom HP infection was erradicated, and 28 HP Positive patients in whom infection was not eradicated following treatment. Dyspeptic symptoms were assessed using SODA scale. RESULTS: There was significant differences on decrease of pain (RR= 0.6, IC 90%: 0.47 -0.78) and non-pain symptoms intensity (RR= 0.5, IC 90%: 0.39 - 0.67), as well as on increase on degree of satisfaction (RR= 3.28, IC 90%: 2.86 - 3.75) among HP Negative patients group with regards to HP Positive patients at sixth month. CONCLUSIONS: In patients with nonulcer dyspepsia, erradication of HP infection is associated with decrease in symptoms intensity and increase on degree of satisfaction six month after treatment.

[Obscure gastrointestinal bleeding as initial presentation of Crohn's disease diagnosed by small intestinal capsule endoscopy]. / Hemoragia Digestiva Oscura como presentación inicial de Enfermedad de Crohn del Intestino Delgado diagnosticada por Cápsula Endoscópica.

The present case illustrates a patient with obscure gastrointestinal bleeding which MiroCam capsule endoscopy showed erosions and ulcers from distal jejunum to ileum. Considering that ileal ulcers where closer to ileocecal valve, ileoscopy was repeated. Diagnosis with new biopsies was Crohn disease. Capsule endoscopy is an innovative technology, which let us have high resolution color pictures through gastrointestinal tract for more effective and diagnostic view of small bowel in a minimal invasive way. New guidelines in obscure GI bleeding agreed that initial diagnostic imaging of the small bowel should be performed using capsule endoscopy. Ballon assisted enteroscopy, angiography and laparoscopy should be used as a follow-up procedure for targeted endoscopic treatment or for obtaining histopathological diagnosis.

Presentamos el caso de una paciente con sangrado digestivo oscuro que la cápsula endoscópica MiroCam® (CE) demostró lesiones erosivas y ulcerativas que comprometían yeyuno distal e ileón. Esto orientó a repertir la ileoscopía para biopsiar y precisar el diagnóstico de Enfermedad de Crohn. La cápsula endoscópica es una tecnología innovadora que nos permite tener fotografías de alta resolución a lo largo del tracto digestivo para un diagnóstico más preciso de patologías del intestino delgado de una manera mínimamente invasiva. Actualmente, las guías en sangrado oscuro aconsejan realizar el estudio de cápsula endoscópica antes de otros métodos más complejos. La enteroscopía asistida por balón, angiografía o laparoscopía deberían ser realizados teniendo en consideración los resultados obtenidos por CE con la finalidad de realizar terapéutica u obtener biopsias.

The present case illustrates a patient with obscure gastrointestinal bleeding which MiroCam® capsule endoscopy showed erosions and ulcers from distal jejunum to ileum. Considering that ileal ulcers where closer to ileocecal valve, ileoscopy was repeated. Diagnosis with new biopsies was Crohn disease. Capsule endoscopy is an innovative technology, which let us have high resolution color pictures through gastrointestinal tract for more effective and diagnostic view of small bowel in a minimal invasive way. New guidelines in obscure GI bleeding agreed that initial diagnostic imaging of the smallbowel should be performed using capsule endoscopy. Ballon assisted enteroscopy, angiography and laparoscopy should be used as a follow-up procedure for targeted endoscopic treatment or for obtaining histopathological diagnosis.

[Prospective validation of the Rockall Scoring System in patients with upper gastrointestinal bleeding in Cayetano Heredia Hospital Lima- Peru]. / Estudio prospectivo de validacion del Sistema de Score de Rockall en pacientes con hemorragia digestiva alta en el Hospital Nacional Cayetano Heredia De Lima- Peru.

INTRODUCTION: The present study intends to validate the Rockall Score in patients with upper gastrointestinal bleeding (UGB) in our current medical setting and to find the value that best discriminates between patients with high or low risk of mortality, rebleeding and the need of more than two units of packed red blood cells (PRBC). MATERIALS AND METHODS: A descriptive prospective study was made from patients who arrived to Cayetano Heredia Hospital's emergency department between February 2007 and January 2008 due to UGB symptoms (hematemesis, coffe ground remit melena or hematoquezia). The Rockall score was used to determine severity of UGB and to stratify patients with higher risk of mortality or rebleeding. All patients were interviewed and any additional information was gathered from medical history records and emergency and hospitalization endoscopic procedure reports. During the study all patients were evaluated for rebleeding, the number of units of PRBCs needed and mortality rate. RESULTS: 163 patients were included in our study, 107 (65.64%) were male and 56 (34.36%) female, 8 were excluded due to lack of an endoscopic procedure. The remaining 155 patients were studied to evaluate the discriminative ability of the scoring system, and to determine which value best distinguishes high and low severity patients using Receiver Operating Characteristic curve (ROC) and calculated area under the curve. The data analysis showed patients with a Rockall Score e 5 had an increased mortality rate compared to lower score with an area under the curve of 0.807, meaning an accurate relationship between mortality and a score e 5. For rebleeding and the need of two packed red blood cells for transfusion, the area under the curve were 0.65 and 0.64 respectively showing a low predictive value. CONCLUSION: The Rockall scoring system is useful to identify patients with high mortality risk, but not to predict rebleeding or the need for blood transfusion in our hospital.
