    ABSTRACT: Hospital-acquired pneumonia (HAP) is one of the leading nosocomial infections and is associated with high morbidity and mortality. Numerous studies on HAP have been performed in intensive care units (ICUs), whereas very few have focused on patients in general wards. This study examined the incidence of, risk factors for, and outcomes of HAP outside the ICU. An incident case-control study was conducted in a 600-bed hospital between January 2006 and April 2008. Each case of HAP was randomly matched with 2 paired controls. Data on risk factors, patient characteristics, and outcomes were collected. The study group comprised 119 patients with HAP and 238 controls. The incidence of HAP outside the ICU was 2.45 cases per 1,000 discharges. Multivariate analysis identified malnutrition, chronic renal failure, anemia, depression of consciousness, Charlson comorbidity index ≥3, previous hospitalization, and thoracic surgery as significant risk factors for HAP. Complications occurred in 57.1% patients. The mortality attributed to HAP was 27.7%. HAP outside the ICU prevailed in patients with malnutrition, chronic renal failure, anemia, depression of consciousness, comorbidity, recent hospitalization, and thoracic surgery. HAP in general wards carries an elevated morbidity and mortality and is associated with increased length of hospital stay and increased rate of discharge to a skilled nursing facility.

    ABSTRACT: To assess the value of intraoperatory radioguided probe detection to guide surgical resection of malignant lesions previously detected by (18)F-FDG PET-CT. Twelve consecutive patients with suspected tumor recurrence detected by (18)F-FDG PET-CT considered resectable were enrolled in the study. Ultrasound guided fine needle aspiration (FNA) before surgery was performed in 6 patients and CT guided biopsy was performed in 1 patient. In 5 patients with accessible lesions, a radioguided occult lesion localization (ROLL) technique was performed after injection of (99m)Tc-colloid (1.7-2.4 mCi) inside the lesion under ultrasound or CT guidance, pre-operatively. Radioguided surgical detection was then carried out 19-24 hours afterwards using the gamma probe. In 7 patients with non-accessible needle lesions or multiple lesions, 9.5-10.5 mCi of (18)F-FDG were injected 3-5 hours before radioguided surgery using a PET-dedicated probe (Gamma locator DXI-GF&E). ROLL technique: All lesions injected with nanocolloid were resected (6 lesions in 5 patients, 1 patient with 2 lesions), and recurrence was histologically confirmed. PET probe: Fourteen out of 16 hypermetabolic lesions detected on the PET-CT were resected. One cervical and one mediastinal lymph node in different patients could not be excised. Histological recurrence was confirmed in 12 out of 14 lesions. In one patient, the 2 lymph nodes excised were inflammatory. (18)F-FDG PET-CT can be key in deciding surgical approach and appropriate radioguided protocol. When lesions are solitary and easily accessible, ROLL technique seems the method of choice. PET probe is more adequate for less accessible lesions.

    ABSTRACT: To analyse the results obtained in the diagnosis and staging of lung cancer (LC) by a Lung Cancer Rapid Diagnosis Unit (LC-RDU) in which real-time endobronchial ultrasound-guided transbronchial needle aspiration (RT-EBUS guided-TBNA) is performed as part of the clinical evaluation of the patient prior to treatment. A four year observational study was conducted on a group of patients evaluated due to suspicion of LC in an LC-RDU. The times and the techniques required for the diagnosis and identifying the level of the disease in the initial staging were recorded. Out of a total of 678 patients seen in the LC-RDU, the diagnosis in 352 was confirmed in one or more histopathology samples. In 170 patients (48.2%) the diagnosis was made with biopsies and/ or cytology samples obtained by fibrobronchoscopy, and RT-EBUS guided-TBNA confirmed the clinical suspicion in 70 patients (19.9%). In the 280 patients with SCLC, 166 RT-EBUS guided-TBNA were performed for staging (59.3%), and in 105 of them the technique only showed local disease (37.5%). Therapeutic surgery was performed on 83 of these patients, and was radical in 73 cases (87.9%). In half of the patients referred to the LC-RDU due to suspected LC, the diagnosis was confirmed in 75% of cases using endoscopic techniques. RT-EBUS guided-TBNA was the diagnostic technique in 20% of the cases, for staging in more than half of them, and led to reduced waiting times for the diagnosis and starting treatment.

The times and the techniques required for the diagnosis, the treatment period and the level of the disease in the initial staging were recorded.ResultsOut of a total of 678 patients seen in the LC-RDU, the diagnosis in 352 was confirmed in one or more histopathology tests. In 170 patients (48.2%) the diagnosis was made with biopsies and/ or cytology samples obtained by fibrobronchoscopy, and RT-EBUS guided-TBNA confirmed the clinical suspicion in 70 patients (19.9%). In the 280 patients with NSCLC, 166 RT-EBUS guided-TBNA were performed for staging (59.3%), and in 105 of them the technique only showed local disease (37.5%). Eighty-three of these patients underwent therapeutic surgery, which was radical in 73 cases (87.9%).ConclusionIn half of the patients referred to the LC-RDU due to suspected LC, the diagnosis was confirmed in 75% of cases using endoscopic techniques. RT-EBUS guided-TBNA, which was the diagnostic technique in 20% of the cases and for staging in more than half of them, led to reduced waiting times to diagnosis and onset to treatment.ResumenObjetivoAnalizar los resultados conseguidos en diagnóstico y estadificación del cáncer de pulmón (CP) por una unidad de diagnóstico rápido de cáncer de tórax (UDR-CT) que incorpora la ultrasonografía endobronquial con punción transbronquial aspirativa en tiempo real (USEB-PTBA-tr) a la evaluación clínica del paciente previa al tratamiento.MétodoSe ha realizado un estudio observacional del conjunto de pacientes valorados por sospecha diagnóstica de CP en una UDR-CT durante cuatro años, registrando los tiempos y la técnica requeridos para el diagnóstico, el tiempo para el tratamiento, y el grado de identificación de enfermedad en estadio inicial.ResultadosSeiscientos setenta y ocho pacientes fueron atendidos en la UDR-CT, en 352 casos el diagnóstico fue confirmado en una o más muestras anatomopatológicas. En 170 pacientes el diagnóstico se obtuvo con biopsias y/o citologías obtenidas por fibrobroncoscopia (48,2%), la USEB-TTBA-rt confirmó la sospecha clínica en 70 pacientes (19,9%). En 280 pacientes afectos de carcinoma de pulmón no célula pequeña (CPNCP) se practicaron 166 USEB-PRBA-tr de estadificación (59,3%) y en 105 de ellos la técnica mostró únicamente enfermedad local (37,5%). En 83 de estos pacientes se procedió a cirugía terapéutica, que fue radical en 73 casos (87,9%).ConclusiónEn la mitad de pacientes remitidos a la UDR-CT por sospecha de CP el diagnóstico se confirma, por técnicas endoscópicas en tres cuartas partes de los casos. La USEB-TTBA-rt es la técnica diagnóstica en una quinta parte de los casos y de estadificación en más de la mitad de ellos, y permite reducir los tiempos de espera hasta el diagnóstico y el inicio de tratamiento.
