[Acute poisoning in patients over 65 years of age]. / Intoxicaciones agudas en pacientes mayores de 65 años.

BACKGROUND: There are few Spanish studies on acute poisoning in the elderly despite the associated risk factors of this group of patients. MATERIAL AND METHODS: Retrospective descriptive study of acute poisonings treated in the Emergency Service of the University Hospital of Zaragoza from 1995 to 2009 on patients 65 years old or older. RESULTS: A total of 762 patients were selected in the study (4.74% of all acute poisonings) with a mean age of 74.16 (SD ± 6) years. Ingestion was the major route of exposure (85%) and alcohol overdose (28,7%) was the most frequent type of poisoning. A trend was also observed showing a lower emetic treatment and gastric lavage and an increase in activated charcoal. Benzodiazepines (14.3%) and toxic household products (11%) with caustic properties were also the main toxics found in the study. CONCLUSIONS: Acute poisonings in the elderly required more hospitalizations, have a higher mortality and more autolytic attempts which result in death.

Intoxicaciones agudas en pacientes mayores de 65 años / Acute poisoning in patients over 65 years of age

Fundamento: Los estudios sobre la intoxicación aguda en sujetos de edad avanzada en nuestro país son escasos, a pesar de los riesgos asociados que presenta este grupo de pacientes. Material y métodos: Estudio descriptivo retrospectivo de las intoxicaciones agudas atendidas en el servicio de Urgencias del Hospital Clínico Universitario de Zaragoza entre 1995 y 2009, en pacientes con edad igual o mayor a 65 años. Resultados: Se registraron 762 casos, el 4,74% del total de intoxicados, con una edad media de 74,16 (SD ± 6) años. La vía oral fue la más frecuente (85%) y por tipo de intoxicación, la sobredosis de alcohol (28,7%). Junto a éste, las benzodiacepinas (14,3%) y los productos cáusticos (11%) fueron los principales tóxicos involucrados. El 21% de los pacientes recibieron tratamiento específico antitóxico, no precisando ingreso el 82,4%. Se observó en la evolución temporal una tendencia que apuntaba a la disminución del tratamiento emético y del lavado gástrico y un aumento del carbón activado. La mortalidad de la serie fue del 1,04%. Conclusiones: Las intoxicaciones en pacientes mayores presentan una mayor morbimortalidad, precisando más ingresos y más tentativas autolíticas con resultado de muerte (AU)

[Nephritic colic management in an emergency room of a referral hospital]. / Manejo del cólico renal en urgencias de un hospital de tercer nivel.

BACKGROUND: To evaluate the diagnostic and therapeutic management of patients with nephritic colic in a referral hospital, their monitoring and the incidence of alternative diagnoses. METHODS: This is a retrospective review of 182 randomly selected patients who presented a clinical diagnosis compatible with nephritic colic in a referral hospital. In these cases initial treatment, monitoring and alternative diagnoses have been evaluated. RESULTS: Fifty-five point four percent of the patients were male, the mean age was 47.7 years and 40% of the cases were in spring. Urinalysis was carried out in every patient (62.7% dipstick and 72% urinary sediment); they were pathological in over 70%. In 26.4% of cases renal function deteriorated, always transiently. Abdominal radiography (81.9%) was the most frequently diagnostic test performed, followed by ultrasound (25.8%). Treatment included a serum therapy in 31.3%; metamizol (61%) was the most commonly used analgesic followed by ketorolac (44.5%). More than one non-steroidal anti-inflammatory was used by 46.2%. Hospital admission was required by 24 patients, and 5 of them needed emergency surgery. Twenty-four point one percent of patients had relapses during the next six months. Forty-one point six percent were referred to urology discharge on from the emergency room. Eighteen point one percent of patients had alternative diagnoses; acute pyelonephritis was the most frequent of these (55%). CONCLUSIONS: In our work we found a significant variation in the diagnostic and therapeutic management of these patients. The use of clinical guidelines could help us to unify the management of patients with nephritic colic, both in the emergency room and on discharge. Due to the high prevalence of alternative diagnoses, we have to systematically exclude more serious diseases.

Dolor abdominal en paciente con bulimia nerviosa / Abdominal pain in bulimic patient

La incidencia de bulimia nerviosa ha cobrado importancia en los países occidentales en las últimas décadas. La dilatación gástrica aguda es un proceso muy grave e infrecuente en pacientes sin antecedentes de enfermedad digestiva. Sin embargo, se han descrito casos en pacientes con alteraciones de la conducta alimentaria, especialmente después de ingestas compulsivas. Las complicaciones de la dilatación gástrica aguda son la necrosis isquémica del órgano y la perforación que pueden conducir a una situación de shock irreversible. El diagnóstico precoz y la evacuación gástrica, incluso en fases incipientes de isquemia y necrosis pueden evitar la realización de una laparotomía. Se debería realizar una cuidadosa investigación de los hábitos alimentarios con objeto de ofertar un tratamiento precoz. Presentamos el caso de una mujer de 24 años que padecía bulimia nerviosa e ingresó por una dilatación gástrica aguda y revisamos las características más importantes de esta entidad (AU)

The incidence of bulimia nervosa has attained significance in the last decades in the Western countries. Massive gastric dilatation is a very serious condition that is extremely rare in patients with no background of gastrointestinal disease. However, several cases have been reported in patients with eating disorders, particularly after a compulsive ingestion. Complications of acute gastric dilatation are infarction and perforation with severe and irreversible shock. Prompt diagnosis of acute gastric dilatation and decompression of the stomach even when gastric ischemia and mucosal necrosis is present may avoid unnecessary laparotomy. Careful investigation of eating habits may result in therapeutic gastric emptying at an earlier stage. We present a case of a 24-year old woman who suffered bulimia nervosa and was admitted because of acute gastric dilatation. We review the most important features of this condition (AU)

Infección por Coxiella Burnetti (Fiebre Q) / Coxiella Burnetti infection (Q Fever)

La Fiebre Q es una zoonosis de distribución universal. Su verdadera incidencia en España es desconocida y probablemente subestimada. Su presentación clínica puede ser aguda o crónica y muy variada. Presentamos el caso clínico de un paciente de 69 años con neumonía y hepatitis secundaria a infección por Coxiella Burnetti (Fiebre Q). Se ha realizado una revisión de la literatura (AU)

Q Fever is a worldwide zoonosis. Real incidence in unknown and probably underestimated. Clinical manifestations are varied and can be acute and chronic. A case report of a 69 year old man with a pneumonia and hepatitis due to a Coxiella Burnetti infection (Q fever ) is presented. A review of literature was made (AU)

[Pneumonitis associated to methotrexate]. / Neumonitis secundaria a metotrexate.

Methotrexate (MTX) is a folic acid antagonist that inhibits cellular reproduction. MTX has been shown to be an effective anti-inflammatory agent. Acute interstitial pneumonitis is the main pulmonary side effect during MTX treatment. We report a case of MTX pneumonitis in a 56-year old woman with autoimmune thrombocytopenia who presented with subacute nonproductive cough, dyspnea at rest, fever, and malaise. Chest roentgenogram demonstrated bilateral diffuse interstitial and alveolar infiltration. Infectious diseases were ruled out and methotrexate-induced pneumonitis was suspected. MTX was discontinued and methylprednisolone was prescribed. Patient improved progressively. After eight weeks, radiologic abnormalities and symptoms had disappeared.

Neumonitis secundaria a metotrexate / Pneumonitis associated to methotrexate

El metotrexate (MTX) es un antagonista del ácido fólico que inhibe la reproducción celular. El MTX es actualmente utilizado como antiinflamatorio en diferentes procesos. La neumonitis intersticial aguda es el principal efecto secundario pulmonar que ocurre en pacientes tratados con MTX. Describimos el caso de una neumonitis asociada a MTX en una mujer de 56 años con trombopenia autoinmune, que presentó de forma subaguda tos no productiva, disnea de reposo, fiebre y afectación del estado general. En la radiografía de tórax se observaba una afectación intersticial bilateral difusa e infiltración alveolar. Se descartó una causa infecciosa del cuadro y ante la sospecha de neumonitis asociada a MTX, se procedió a su retirada. Se administró metilprednisolona, observándose una mejoría progresiva. Tras ocho semanas las alteraciones clínicas y radiológicas habían desaparecido

Lack of clinical usefulness of interleukin-6 in long-term follow-up of acutely decompensated heart failure.

INTRODUCTION: Interleukin-6 (IL-6) has been identified as a predictor of death, new heart failure (HF) episodes and need for heart transplantation in patients with advanced HF. The aim of this study was to examine the relationship between plasma IL-6 levels in patients with decompensated HF and either survival or new admissions due to HF. METHODS: We studied 111 patients admitted due to decompensated HF. Long-term survival was assessed from the day of admission to the hospital to the day of death or new admissions due to HF. RESULTS: The mean IL-6 concentration was 90 +/- 115 pg/ml (range 1.5-743 pg/ml). There were no differences in IL-6 concentration with regard to age, gender and cause of HF. At the end of follow-up period, 22 patients (20 percent) had died due to causes related to HF and 54 patients (48 percent) had been readmitted to the hospital due to new HF episodes. Using regression analyses, serum IL-6 levels were not identified as a prognostic factor. Systolic dysfunction, previous diagnosis of HF and diabetes mellitus were independent predictors of death. CONCLUSION: These findings suggest that a single measurement of serum IL-6 in patients with decompensated HF lacks clinical usefulness in long-term follow-up.

[Spontaneous pneumomediastinum]. / Neumomediastino espontáneo.

Spontaneous pneumomediastinum (defined by the presence of free air in the mediastinum) is an infrequent entity that is presented in the absence of diseases or precipitating factors. It generally affects young and healthy males. Thoracic pain, dyspnea, or both, are the most frequent symptoms. Other signs and symptoms are subcutaneous emphysema and Hamman's sign. Simple radiography of the thorax allows for the diagnosis in a high percentage of patients. Conservative treatment is indicated in these patients and has a favourable prognosis. Relapses are infrequent.

Osteosíntesis de fracturas del fémur distal con placas LISS / Distal femoral fractures; treatment with less invasive stabilitation system (L. I. S. S.)

Las fracturas del fémur distal son complejas en su tratamiento y asocian múltiples complicaciones evolutivas com pseudoartrosis, callos viciosos, gonartrosis o infección secundaria a cirugía abierta agresiva, por lo que han surgido las osteosíntesis mínimamente invasivas dentro de las cuales se sitúa la placa LISS. Analizamos los resultados tras 10 meses de seguimiento de 14 pacientes con fractura del fémur distal tratados con placa LISS. Los tiempos de consolidación no fueron muy divergentes respecto a series mayores, la incidencia de retrasos de consolidación y callos viciosos, baja. No hubo pseudoartrosis, fracasos del material, aflojamientos, infecciones, tromboembolismos ni algodistrofias. Por ello, consideramos que los resultados obtenidos con este implante son satisfactorios

The treatment of the distal femoral fractures is difficult in order to the surgery and múltiple complications, like pseudoartrosis,c allus vicious, gonartrosis or infection because open surgery. So that it has arised the minimun invasive system of osteosynthesis like LISS plate. We have assessed outcomes in 14 patients with distal femoral fractures treated with that implant. The mean follow up was 10 months. The times of consolidation was similar than other bigger series of patients and low incidence of delayed consolidation and callus vicious. There has not been any case of pseudoartrosis, failure of implant, loosenin, infections, tromboembolism or algodystrophia, so that considered that we has obtained good results
