Neumatosis intestinal y gas porto-mesentérico: hallazgos radiológicos y significado clínico en un caso de catástrofe abdominal / Pneumatosis intestinalis and portall venus gas: radiological findings and clinical significance in a case of abdominal catastrophe

Presentamos el caso de una mujer de 56 años de edad, con dolor abdominal de cinco días de duración asociado a manifestaciones inespecíficas y sin etiología clara del dolor. Se realizaron estudios en busca del origen del dolor con los que se documentó neumatosis intestinal grave, que posteriormente se agravó a pesar del manejo medico. Debido al mal estado hemodinámico y el rápido deterioro clínico luego de la evaluación médica no pudo ser llevada a cirugía y la paciente fallece.

We report a 56-year-old woman with abdominal pain 5 days duration associated with nonspecific manifestations without etiology of pain. We conducted studies in search of the source of pain between these severe intestinal pneumatosis that progress despite medical management and could not be taken to surgery due to hemodynamic state to a rapid deterioration after medical evaluation and documented patient dies. Finally, we review this case and the most frequent finding of portomesenteric venous gas.

Síndrome de arteria mesentérica superior secundario a quemadura severa / Superior mesenteric artery syndrome caused by severe burn

El síndrome de la arteria mesentérica superior (síndrome de Wilkie) es una causa poco frecuente de obstrucción duodenal. El síndrome resulta por la compresión de la tercera porción del duodeno, que cruza por debajo de la arteria mesentérica superior. Se asocia con situaciones que disminuyen el ángulo entre la arteria mesentérica superior y la aorta (compás aorto-mesentérico), secundarias a pérdida de grasa retroperitoneal (descenso brusco de peso o caquexia). Describimos el caso de un paciente masculino de 17 años con quemaduras de segundo grado y compromiso del 28 % de la superficie corporal total, quien posteriormente presentó vómito, distención abdominal e intolerancia a la vía oral y en quien, luego de múltiples estudios, se confirma el diagnóstico de síndrome de Wilkie.

Superior mesenteric artery syndrome is an uncommon cause of upper gastrointestinal tract obstruction. The syndrome results from compression of the third portion of duodenum as it crosses underneath the superior mesenteric artery. It is associated with conditions that decrease the angle between the superior mesenteric artery and the aorta (aorto-mesenteric compass) secondary to loss of retroperitoneal fat (sudden decrease in weight or cachexia). In this article, we describe a male patient of 17 years old with deep second degree burns, 28% of the total body surface, who later started to vomit associated with abdominal distension and intolerance to food and after multiple studies confirmed the diagnosis of Wilkie's syndrome.

Esquizofrenia y trastorno en el consumo de sustancias: prevalencia y características socio-demográficas en la población Latina / Substance use disorder and schizophrenia: prevalence and sociodemographic characteristics in the Latin American population

El interés por comprender la comorbilidad de la esquizofrenia y el trastorno en el uso de sustancias, ha aumentado debido al incremento de este diagnóstico, a los efectos negativos observados en el sujeto y a los costos en los servicios de salud. Este trastorno dual puede tener efectos dramáticos en el curso clínico del trastorno psicótico tales como: mayores recaídas, re-hospitalizaciones, síntomas más severos, no adherencia al tratamiento antipsicótico, cambios marcados del humor, aumento en el grado de hostilidad e ideación suicida, así como alteraciones en otras áreas del funcionamiento incluyendo violencia, victimización, indigencia y problemas legales. La literatura proveniente en particular de Estados Unidos y Europa sugiere que el rango de prevalencia para este diagnóstico puede oscilar entre el 10% hasta el 70%.En este estudio, revisamos la prevalencia del diagnóstico dual de esquizofrenia y trastorno en el uso sustancias, así como sus características sociodemográficas, con base en la literatura disponible alrededor del mundo dando énfasis en la población latina. A pesar de que este diagnóstico es ampliamente aceptado, se conoce poco sobre su prevalencia en la población latina, sobre los factores ambientales, demográficos, clínicos y otras características de estos individuos. Un mejor conocimiento sobre este diagnóstico permitiría mejorar los métodos para la detección y adecuada valoración del trastorno en el uso de sustancias en personas con trastornos metales severos como la esquizofrenia (AU)

Interest in understanding the comorbidity of schizophrenia and substance use disorder has been increasing due to the increase of this diagnosis, to the negative effects observed in the subject and to the health service costs. This dual disorder can have dramatic effects on the clinical course of the psychiatric disorder, this being, for example increased relapses, re-hospitalizations, more severe symptoms, non-compliance with antipsychotic medication, marked mood changes, increased rates of hostility and suicidal ideation as well as in other areas of functioning, including interpersonal violence and victimization, homelessness, and legal problems. Literature from the United States and Europe in particular suggests that the prevalence rates for this dual diagnosis may range from 10 to 70%. In this study, we have reviewed the prevalence of the dual diagnosis of schizophrenia and substance use disorder as well as the sociodemographic characteristics in the literature on Latin-American populations. Notwithstanding that the dual disorder is a widely accepted diagnosis, relatively little is known about its prevalence in Latin American populations or about the environmental factors that may influence it, as well as about the demographic, clinical, and other characteristics of these individuals. A better understanding of this diagnosis might improve the methods for the detection and assessment of substance use disorder in persons with severe mental illness such as schizophrenia (AU)

Substance use disorder comorbidity with schizophrenia in families of Mexican and Central American ancestry.

OBJECTIVES: The aims of this study were to estimate the frequency and course of substances use disorders in Latino patients with schizophrenia and to ascertain risk factors associated with substance use disorders in this population. METHOD: We studied 518 subjects with schizophrenia recruited for a genetic study from the Southwest United States, Mexico, and Central America (Costa Rica and Guatemala). Subjects were assessed using structured interviews and a best estimate consensus process. Logistic regression, chi(2), t test, Fisher's exact test, and Yates' correction, as appropriate, were performed to assess the sociodemographic variables associated with dual diagnosis. We defined substance use disorder as either alcohol or substance abuse or dependence. RESULTS: Out of 518 patients with schizophrenia, 121 (23.4%) had substance use disorders. Comorbid substance use disorders were associated with male gender, residence in the United States, immigration of Mexican men to the United States, history of depressive syndrome or episode, and being unemployed. The most frequent substance use disorder was alcohol abuse/dependence, followed by marijuana abuse/dependence, and solvent abuse/dependence. CONCLUSION: This study provides data suggesting that depressive episode or syndrome, unemployment, male gender, and immigration of Mexican men to the United States were factors associated with substance use disorder comorbidity in schizophrenia. Binary logistic regression showed that country of residence was associated with substance use disorder in schizophrenic patients. The percentage of subjects with comorbid substance use disorders was higher in the Latinos living in the United States compared with subjects living in Central America and Mexico.
