Seasonal adjustment of the Spanish sales daily data.

We present a procedure to perform seasonal adjustment over daily sales data. The model adjusts daily information from the Immediate Supply of Information System for Value Added Tax declaration forms compiled by the Spanish Tax Agency. The procedure performs signal extraction and forecasting at the daily frequency, by means of an unobserved components model.

Spontaneous circumferential esophageal dissection in a young man with eosinophilic esophagitis.

Spontaneous esophageal dissection is a rare condition that may happen in patients with eosinophilic esophagitis. Conservative management is an important therapeutic option to be considered. We describe an unusual case of a young man with eosinophilic esophagitis who presented complaining of acute retrosternal pain, fever and vomiting.

Middle lobectomy after pneumonectomy.

A 59-year-old man underwent a successful middle lobectomy to treat metastasis from a pulmonary adenocarcinoma resected previously by left pneumonectomy.

Primary synovial sarcoma of the lung.

A 45 -year-old woman presented chest pain and a well-defined oval shaped mass on a chest radiograph. A malignant pulmonary tumor was suspected and a right pneumonectomy was performed. The tumor measured about 13 x 12 cm, was pale-yellow in color and soft in texture.

Minimally invasive surgical implantation of left ventricular epicardial leads for ventricular resynchronization using video-assisted thoracoscopy.

Background And Objectives: Cardiac resynchronization via left ventricular or biventricular pacing is an option for selected patients with ventricular systolic dysfunction and widened QRS complex. Stimulation through a coronary vein is the technique of choice for left ventricular pacing, but this approach results in a failure rate of approximately 8%. We describe our initial experience with minimally invasive surgical implantation of left ventricular epicardial leads using video-assisted thoracoscopy.
