Mesenteric actinomycosis with retroperitoneal involvement.

Mesenteric or retroperitoneal actinomycosis is an extremely rare disease. The international databases have revealed only 10 cases affecting the mesenterium and another 52 cases affecting the retroperitoneum. We report a 78-year-old female who was admitted with complaints of abdominal pain. Laboratory examination revealed anemia and the clinical examination revealed an irregular mass in the abdomen. Ultrasound and computed tomography (CT) scans showed a solid mass in the mesenteric-retroperitoneal region. Biopsy of the nonresectable mass revealed the presence of chronic inflammation in the mesenteric area with Actinomyces colonies. The patient was treated with oral amoxicillin, 500 mg every 6 hours for 6 months. The symptoms disappeared, but the mesenteric-retroperitoneal mass remains, but smaller in size. Based on the review of the literature and the case reported here, we conclude that mesenteric-retroperitoneal actinomycosis is difficult to diagnose by means of noninvasive techniques as it can masquerade as a malignant process. An accurate diagnosis is always obtained in a histological or microbiological examination, often requiring surgical intervention. Treatment with penicillin has proven to be effective.

Utilidad clínica de la elastasa polimorfonuclear en las pancreatitis agudas / Clinical utility of polymorphonuclear elastase in acute pancreatitis

Introducción. La elastasa polimorfonuclear es una proteasa localizada en los lisosomas de los leucocitos polimorfonucleares que se libera como mecanismo de defensa para eliminar los productos de degradación tisular en el lugar de la inflamación. En este trabajo se evalúa la utilidad de la determinación de la elastasa como factor pronóstico en pacientes con pancreatitis aguda. Pacientes y método. Se realiza un estudio prospectivo sobre la utilidad de la medida de la elastasa en una serie de 31 pacientes con pancreatitis aguda. Se les efectuó, dentro de los primeros 3 días del ingreso hospitalario, la determinación de hemograma, bioquímica, elastasa polimorfonuclear y proteína C reactiva, además de la evaluación clínica -mediante criterios de Ranson- como grave y leve. Resultados. Se ha encontrado una serie de 7 pacientes con una elastasa media (ñ DE) de 301 ñ 277 µg/l y proteína C reactiva de 14,3 ñ 17,1 mg/dl, que se asocian a una evolución tórpida. En los otros 24 pacientes, la elastasa fue 109 ñ 115 µg/l, y proteína C reactiva de 4,84 ñ 5,87 mg/dl, presentando una evolución favorable. Conclusiones. Existen diferencias significativas entre los dos grupos en ambos parámetros. Tanto la elastasa polimorfonuclear como la proteína C reactiva, junto con otros datos clínicos y el recuento leucocitario, constituyen unos parámetros útiles para diferenciar las pancreatitis agudas graves de las leves (AU)

Mesotelioma maligno en la región inguinal de origen incierto / Malignant mesothelioma of unknown origin in the inguinal region

Se presenta un caso de mesotelioma maligno en una paciente joven, localizado en la región inguinal y sin aparente relación con ningún saco herniario ni cavidad peritoneal. Se revisa la bibliografía existente, sin encontrar ninguna otra forma igual de mesotelioma (AU)

[Stomach in inguinal-scrotal hernia]. / Estómago en hernias ínguino-escrotales.

We present two cases of inguinoscrotal hernia that contains stomach, both associated with a chronic obstructive pulmonary disease; one of them is shown with a intermittent gastric obstruction syndrome, the other being a radiological finding in a patient with dispeptic symptoms. The first one died of a respiratory infection, before operation, and the second refused operation because of his scarce symptomatology. A review of the literature shows 60 cases reported including our cases.

[Verrucous carcinoma of the anal margin. The Buschke-Loewenstein tumor]. / Carcinoma verrucoso del margen anal. Tumor de Buschke-Loewenstein.

The Buschke-Loewenstein tumour is a rare variety of squamous cell carcinoma of low-grade malignancy; it is located in the external genital organs and the perianal region. We present a new case of this uncommon tumour of short evolution in a 73 years old male patient. Resection was the only treatment, without relapse at 12 months. A review of the literature shows only 13 cases previously published; we comment the human papillomavirus role in their pathogenesis and the various therapies proposed, concluding that the best is surgical treatment.

[Synchronous intestinal, tonsillar and pulmonary tuberculosis]. / Tuberculosis intestinal, amigdalar y pulmonar sincrónicas.

OBJECTIVES: To emphasize the unusual synchronous presentation of intestinal, pulmonary and tonsillar tuberculosis in the same patient. CLINICAL CASE: A 43 years old male consults for abdominal pain and alternating episodes of diarrhoea-constipation. Based on radiologic, endoscopic and pathologic studies the diagnosis of Crohn's ileo-cecal disease is achieved and a treatment with salazosulphapyridine and corticosteroid is started. Two months later the patient presents with a tonsilar ulceration that is diagnosed as tuberculosis on biopsy material. At the same time, chest x-rays film reveal active tuberculous lesions, and tuberculous bacili are seen in the sputum. Simultaneously the intestinal disease worsens and complicates with incomplete occlusion that requires a right hemicolectomy. Pathologic study of the specimen shows evident tuberculous lesions. Specific treatment for tuberculosis is started, and the patient remains free of disease one year later. CONCLUSIONS: Due to the increase in the prevalence of tuberculous diseases, we must keep it in mind in the differential diagnosis of intestinal strictures, even though they are suggestive of Crohn's disease, and a radical surgical procedure must also be evaluated.

[Biliary surgery on those over 70: an analysis of 109 cases]. / La cirugía biliar en mayores de 70 años: análisis de 109 casos.

109 patients older than seventy years of age and operated of gallstone disease in our service during a period of 4.5 years are presented. The average age of the series was 78.8 years, with a male/female (M/F) ratio of 1/1.6. 77% of the patients were admitted on an emergency basis due to a complication derived from the gallstone disease they were suffering. Only 39.8% of the patients were previously diagnosed of gallstone disease at the time of admission and 10% presented an associated surgical condition which was treated simultaneously. Overall morbidity of the series was 36%, with a mortality of 2 cases (1.9%).
