Primary pulmonary artery sarcoma: a new surgical technique for pulmonary artery reconstruction using a self-made stapled bovine pericardial graft conduit.

Primary pulmonary artery sarcoma is an uncommon neoplasm with a grim prognosis. Complete resection is the only treatment that can improve the patient's survival. The role of multimodality treatment is still controversial, although adjuvant chemotherapy possibly could improve outcomes of these patients. Several pulmonary artery reconstructive techniques have been reported in the scientific literature, such as patch reconstruction, end-to-end anastomosis, synthetic prosthesis or biological grafts. In this article, we propose a new surgical option for pulmonary artery reconstruction after radical tumour resection using a self-made stapled bovine pericardial graft conduit in a patient with a mass in the pulmonary trunk and right pulmonary artery. We believe that the use of this technique adds safety and effectiveness, and reduces the surgical time.

Nonintubated bilateral single port thoracoscopic sympathectomy in the context of an outpatient program, the least invasive management for hyperhidrosis surgery.

Primary hyperhidrosis is a frequent dysfunctional disorder characterized by excessive sweating in amounts greater than required for physiological needs. Surgery remains the mainstay of treatment when there is no response to medical therapies. Traditionally, thoracoscopic sympathectomy is performed routinely by means of general anesthesia with endotracheal intubation. Here we report the least invasive management for hyperhidrosis surgery, a nonintubated bilateral single port thoracoscopic sympathectomy in the context of an outpatient program.

Giant thymolipoma: case report of an unusual mediastinal tumor.

Thymolipoma is an uncommon benign neoplasm of the thymus composed of mature adipose and thymic tissue. The diagnosis of thymolipoma should be considered in the case of a mediastinal mass with fat density, especially if it is interspersed with strands of soft tissue attenuation on computed tomography scans. However, it is sometimes difficult to differentiate radiologically between a thymolipoma and other mediastinal fatty tumors. Here we present a patient with a huge mediastinal mass that proved to be a thymolipoma.

Design and development of a nutritional assessment application for smartphones and tablets with Android OS.

BACKGROUND & AIMS: To design and develop a nutritional application for smartphones and tablets with Android operating system for using to in- and outpatients that need a nutritional assessment. To check the validity of the results of such software. METHODS: The application was compiled for version 2.1 of the Android operating system from Google. A cohort of 30 patients was included for evaluating the reliability of the application. The calculations were performed by staff of the Nutrition Unit of the Complexo Hospitalario Universitario de Vigo, manually and through e-Nutrimet software on a smartphone and a tablet. RESULTS: Concordance was absolute between results of different methods obtained using e-Nutrimet on a smartphone and a tablet (Fleiss index κ= 1). The same level of concordance was obtained by comparing handmade and e-Nutrimet made results. CONCLUSIONS: The degree of correlation is good, and it would be extended to all healthcare staff who wants to determine whether a patient has malnutrition, or not. The nutritional assessment software e-Nutrimet does not replace healthcare staff in any case, but could be an important aid in assessing patients who may be in risk of malnutrition, saving time of evaluation.

Introducción y objetivos: Diseñar y desarrollar una aplicación nutricional para smartphones y tablets con Sistema operativo Android® para realizar las valoraciones nutricionales de pacientes ambulatorios y hospitalizados. Verificar y comprobar la validez de los resultados de la aplicación. Métodos: La aplicación se compile para la versión 2.1 del Sistema operativo Android® de Google®. Para evaluar la fiabilidad de la aplicación se incluyeron a 30 pacientes, a los que se le realizó una valoración nutricional. Todos los cálculos fueron efectuados por personal de la Unidad de Nutrición del Complexo Hospitalario Universitario de Vigo, de forma manual y a través del software e-Nutrimet ©, tanto usando un Smartphone como una tablet. Resultados: Se obtuvo una concordancia absoluta entre los resultados de los diferentes métodos obtenidos utilizando la aplicación e-Nutrimet© en smartphones y en tablets (Fleiss index = 1). El mismo nivel de concordancia se obtuvo comparando el método manual como el automatizado mediante el software e-Nutrimet©. Conclusiones: El grado de correlación es muy bueno, permitiendo extender la valoración nutricional usando e-Nutrimet© a todo el personal sanitario que quiera determinar si un paciente presenta malnutrición o no. La aplicación de valoración nutricional e-Nutrimet© no sustituye al personal sanitario en ningún caso, pero podría ser de gran ayuda a la hora de valorar pacientes que pudieran estar en riesgo de malnutrición, ahorrando tiempo en estas valoraciones.

Primary pulmonary angiosarcoma, an exceptional neoplasm with a poor prognosis: reports of two cases and review of the literature.

Primary pulmonary angiosarcoma is a rare type of malignant vascular tumour characterised by proliferation of tumour cells with endothelial features. Up to date, only sixteen cases have been reported in English Literature. Treatment modalities vary from none to surgery, chemotherapeutic regimens, radiotherapy or immunotherapy, but none of them have been shown to be effective. Unfortunately, these tumours are usually very aggressive and overall mortality is very high. We present two cases of patients with a diagnosis of primary pulmonary angiosarcoma, the largest case series ever described, and a review of the scientific literature.

[Solitary pulmonary nodule: primary, metastatic, or both]. / Nódulo pulmonar solitario: ¿primario, metastásico o ambos?

The lung is the most common site for metastasis from colorectal cancer, which is among the most common neoplasms in developed countries. Simultaneous occurrence of pulmonary metastasis of colorectal origin and primary carcinoma has been reported. We describe the case of a 65-year-old man who underwent low anterior resection for colorectal adenocarcinoma in 2007. Follow-up computed tomography revealed a pulmonary nodule that was classified as metastatic. The patient was referred to our thoracic surgery department, where the nodule was resected. The pathology confirmed that the nodule was neoplastic, and histologic and immunohistochemical examination showed the presence of colorectal metastasis and lung adenocarcinoma. Evidence of metastasis was also found in 2 of the lymph nodes analyzed, 1 with features identical to the primary pulmonary adenocarcinoma, and 1 with features identical to the colorectal metastasis.
