ABSTRACT
In order to know the actual characteristics of bronchiectasis in an adult population, we reviewed 18 cases with this pathology confirmed by spiral CT at a general hospital (Hospital Regional de Concepción, Chile), between 1998-2003. Ten patients were males and 8 females, their mean age was 44 +/- 13.9 years old. Most common etiologies of bronchiectasis were pulmonary tuberculosis (44.4 percent) and acute pneumonia (38.8 percent); main sypmtoms were chronic cough (88.8 percent), persistent sputum (77.7 percent) and hemoptysis (44.4 percent). Spirometry detected airway obstruction in smokers (FEV1/FVC = 58 percent) and in non smokers (FEV1/FVC = 68 percent). Microbiological sputum exams showed Hemophilus influenzae (16.6 percent), Neisseria catharralis (15 percent), Pseudomona aeruginosa (13 percent), Streptococcus pneumoniae (15.4 percent) and Candida albicans (4 percent). Spiral CT showed the following distribution of bronchiectasis: unilobular lesion 11.1 percent, bilobar 72 percent and multilobar 16.6 percent. The clinical picture of bronchiectasis in our hospital according to this up to date review, shows that our reality is essentially similar to that previously reported in literature.
Para conocer las características actuales de las bronquiectasias en adultos en nuestro medio se revisan los 18 casos de esta patología comprobados por TAC helicoidal de tórax en el Hospital Regional de Concepción entre 1998-2003. La edad promedio de los pacientes fue de 44 +/ - 13,9 años; 10 hombres y 8 mujeres. Las etiologías más frecuentes de bronquiectasias fueron tuberculosis pulmonar (44,4 por ciento) y neumonía aguda (38,8 por ciento). Los síntomas más relevantes fueron tos crónica (88,8 por ciento), expectoración persistente (77,7 por ciento) y hemoptisis (44,8 por ciento). La espirometría reveló alteración ventilatoria obstructiva tanto en fumadores (VEF1/CVF = 58 por ciento) como en no fumadores (VEF1/CVF = 68 por ciento). La bacteriología de expectoración detectó Hemophilus influenzae (16,6 por ciento), Neisseria catharralis (15 por ciento), Pseudomona aeruginosa (13 por ciento), Streptococcus pneumoniae (15,4 por ciento) y Candida albicans (4 por ciento). La TAC de tórax demostró lesiones bilobares (72 por ciento), multilobares (16,6 por ciento) y unilobares (11,1 por ciento). La realidad de las bronquiectasias en nuestro medio es que no difiere significativamente de lo descrito en la literatura.

INTRODUCTION: adhesive small bowel obstruction (SBO) is a common cause of hospital admission. Nonoperative management is initially recommended unless there is suspicion of strangulation, but its optimal duration is controversial. The aims of our study was to evaluate the usefulness of radiographic small bowel examination with contrast medium to predict the need for surgery in SBO. MATERIAL AND METHODS: this prospective study carried out from January 1999 to December 2001, included 100 patients with clinical and radiological criteria of adhesive SBO. We described the past medical history, as well as clinical picture, blood tests and radiological findings in these patients. Fifty cubic centimeters of 5% barium suspension were given orally, and plain abdominal radiographs were taken at 4, 8, 16, and 24 hours afterwards. A liquid diet was given as soon as the contrast medium appeared in the right colon. Otherwise, surgical intervention was considered based on the outcome of the patient and the criteria of the emergency surgical team. RESULTS: in 70 patients, barium contrast appeared in the right colon, and a liquid diet was tolerated by 69 of them (98.6%). Mean hospitalization time for this group was 43 +/- 17 hours. In the remaining 30 patients, no evidence of barium contrast in the right colon was seen, and 25 of them underwent surgery (75%), while the other 5 tolerated a liquid diet. Mean hospitalization time for this second group of patients was 13.8 +/- 11 days. Sensitivity, specificity, positive predictive value, and negative predictive value for the absence of contrast medium in the right colon within 24 hours as a predictor of surgery were 93, 96, 98 and 83%, respectively. There was a statistical significant relationship (p < 0.01) between the "Presence of contrast medium in the right colon" and "Oral diet tolerance". Only the variable "Number of previous surgical interventions" tended to reach statistical significance (p = 0.07). Tolerance of liquid diet was more likely when patients had more than one previous abdominal surgery. CONCLUSIONS: early oral administration of a radiological contrast medium in patients with adhesive SBO can effectively predict the need for a surgical procedure. It can shorten not only hospital stay, but also the potential morbidity of late surgery, secondary to a prolonged and unsuccessful nonoperative treatment.

Fine's severity prediction index (SPI), was retrospectively analyzed in community acquired pneumonia (CAP), in patients at Concepción Regional Hospital, from June to August 2000. We studied 57 CAP patients: 23 as low risk and 34 as high risk patients. In comparison to low risk patients the main features of high risk patients were: older age (p < 0.00001), higher comorbility (p < 0.004), longer hospitalization (p < 0.0007) and higher mortality (p < 0.018). Mortality in low risk patients was similar to Fine's study: 4.3 versus 3.5%. In high risk patients mortality was 26% versus 38%. Main complications in our series were mechanical ventilation (43.8%), PaO2/FiO2 < 250 mmHg (43.8%), and hepatic coma (38.5%). As a conclusion, we recommend the use of SPI in CAP at Emergency Services in order to better evaluate mortality, optimizing criteria of hospital admission.
Se evaluó el Índice de Gravedad de Fine (IG) en neumonías de la comunidad (NAC) hospitalizadas en el Hospital Regional de Concepción en trabajo retrospectivo con 57 casos entre Junio y Agosto del año 2000. Se estudiaron 23 pacientes catalogados de bajo riesgo y 34 de alto riesgo. Características de alto riesgo fueron, mayor edad (p < 0,00001), mayor comorbilidad (p < 0,0004), estadía prolongada (p < 0,00007) y mayor mortalidad (p < 0,018). La mortalidad de bajo riesgo fue similar a la de Fine, 4,3% versus 3,5%, siendo menor en el grupo de alto riesgo, 26% versus 38%. Factores de mayor complicación en NAC fueron, ventilación mecánica (43,8%), PaO2/FiO2 < 250 mmHg (43,8%) y coma hepático (35,8%). Conclusión: es aconsejable el uso del IG en NAC a nivel de Servicios de Urgencia, para evaluar los riesgos de mortalidad, optimizando así los criterios de ingreso al hospital.
