[Radiograph patterns in herpes simples virus I pneumonia in the adult]. / Hallazgos radiológicos de la neumonía por virus herpes simple I en el adulto.

The aim of this study is to describe epidemiology, patogénesis, pulmonary manifestations and Rx findings in adult patients with varicella pneumonia (VP). Four patients were studied. The diagnosis was established by clinical and radiologic criteria. All had fever , esanthem, 3 cough, 2 dyspnea. Chest X-ray showed interstitial micronodular pattern at bases. 1 case developed airspace consolidation by Staphylococcus aureus. 2 were admitted to ICU. The four received IV acyclovir. We concluded that adults patients with VP usually show nodular infiltrates, with favourable course.

El propósito de este estudio es describir epidemiología, patogénesis, manifestaciones pulmonares y hallazgos radiológicos en pacientes adultos con neumonía varicelosa (NV). Presentamos a 4 pacientes adultos, el diagnóstico de establecido según clínica y radiología. Todos presentaron fiebre y exantema, 3 tos y 2 disnea. La radiología demostró patrón intersticial micronodular basal. 1 caso de sobreinfección por Staphilococcus aureus. 2 ingresaron en UCI. Todos recibieron tratamiento intravenoso con aciclovir. La NV, suele presentar infiltrados nodulares, siendo generalmente de curso favorable

[Diagnostic performance of mammography in patients with clinically impercetible tumors. Analysis of 1005 tumors]. / Rendimiento diagnóstico de la mamografía en pacientes con lesiones clínicamente ocultas. Análisis de 1005 lesiones.

UNLABELLED: Breast cancer is an important public health problem. Early diagnosis is the only method of efficient secondary prevention in the control of the illness as it permits rapid and effective treatment. The objective of this study was to carry out a methodical analysis that would enable us to increase the diagnostic performance of the mammogram and to diminish the number of unnecessary surgical biopsies. MM: We selected impalpable mammary tumors in patients with radiological suspicion of breast cancer, on which surgical biopsy by harpoon had been practiced in the Lozano Blesa Hospital, Zaragoza, between October 1991 and January 2005. RESULTS: We analyzed a total of 1005 tumors in 965 patients, with an average age of 57 years. In our series of 1005 tumors, 40% were PVV. CONCLUSIONS: The diagnosis of radiological suspicion and the indication for biopsy or mammographic control are subjective and personal appreciations, but based on the systematic analysis of radiological signs of incipient tumors. This analysis enables us to establish a cut-off point to include the tumors in BIRADS.

[Diagnosis of Anisakis infestation: experience in our environment]. / Diagnóstico de la infestación por Anisakis. Experiencia en nuestro medio.

OBJECTIVES: To characterize the most frequently found radiological findings in intestinal anisakiasis. MATERIAL AND METHODS: The medical records of 14 patients diagnosed with intestinal anisakiasis between 2000 and 2003 in the Hospital Clinico Universitario Lozano Blesa in Zaragoza (Spain) were retrospectively reviewed. The imaging tests and immunological laboratory tests performed in these patients were evaluated. RESULTS: The most frequent reason for seeking medical assistance was right iliac fossa pain. Radiological findings of an inflammatory intestinal process were observed in 60 % of the patients. Seventy-five percent of the patients had eaten raw or insufficiently cooked fish and had eosinophilia; of these 80 % had elevated specific IgE levels. CONCLUSIONS: The incidence of anisakiasis is increasing and consequently knowledge of its most characteristic clinical, radiological and laboratory manifestations is important. The most frequently affected segment of the digestive tract is the ileum. Many patients have symptoms of acute abdomen, mimicking appendicitis or peritonitis. Anisakiasis is a self-limiting process that usually resolves in 1-2 weeks. Consequently, a conservative attitude is advisable to avoid unnecessary surgery.

[Life-threatening hemoptysis. Treatment with transcatheter embolization]. / Hemoptisis amenazante. Tratamiento mediante embolización transcatéter.

OBJECTIVE: To evaluate the immediate and long-term efficacy of transcatheter embolization of bronchial, systemic and pulmonary arteries to treat life-threatening hemoptysis. Likewise, we propose the systematic treatment of life-threatening hemoptysis by means of transcatheter embolization. MATERIAL AND METHODS: One hundred seven angiographies were performed on the same number of patients experiencing life-threatening hemoptysis with bleeding exceeding 150 ml in 24 hours. Before angiography, we rinsed the vessels with cold saline solution and adrenalin through the catheter. Thirty-three patients were female and 74 were male. Mean age was 52.3 years (range 12 to 75 years). Embolization was performed in 104 (3 in patients with recurrent hemoptysis) using polyvinyl alcohol and micro-coils. Bronchial and systemic arteries of the affected hemithorax (mammary and lateral thoracic arteries) were checked in all patients. If findings were negative or bleeding was recurrent, we also performed pulmonary arteriography. RESULTS: In two cases we were unable to catheterize the artery theoretically responsible for bleeding. Examination of both arterial and systemic vessels proved normal in one patient. The embolization technique was successful in 99% (103/104) of the cases and the rate of immediate clinical success was 95.1% (99/104). The mean time of follow-up was 43.2 months (range 3 to 66 months). Hemoptysis recurred in 15.3% (16 cases) within a mean 8.3 months (range 15 days to 48 months); embolization was repeated in 14 of these patients with satisfactory results, while two underwent surgery. In five patients (4.8%) we observed complications requiring no additional medical treatment: one instance of coil migration to the deep femoral artery, from which the coil was removed in a basket; two cases of bronchial artery extravasation with small mediastinal hematomas; and two hematomas at the points of puncture. CONCLUSION: Selective or supra-selective embolization of the arteries that feed the bronchi provides effective management of life-threatening hemoptysis. No additional medical treatment is usually required.
