[Traumatic subarachnoid-pleural fistula secondary to non-penetrating thoracic gunshot wound].

INTRODUCTION: Traumatic subarachnoid-pleural fistula (TSPF) is very unusual and is due to the anomalous communication between the pleural and subarachnoid space. We report a TSPF by Bullet wound that was not penetrating to the thoracic cavity. CLINICAL CASE: Masculine of 34 years-old that receives wounded by bullet in the posterior face of thorax. A pleural effusion was identified and medullar wound with fracture of the fifth thoracic vertebra. The effusion is persist and also added headache appear. TSPF was diagnosed for myelography. The patient die before carrying out the surgical treatment. A massive tromboemboly of lug was the cause. The autopsy confirmed the diagnosis. DISCUSSION: The TSPF should be suspected by the association of medullar lesion with a persistent pleural effusion. The diagnosis should be confirmed by radiology. The treatment can be medical or surgical.

[Open vs. closed abdomen in acute peritonitis. A comparative study].

INTRODUCTION: Open abdomen is a management alternative that, however, is not exempt from complications. We evaluated, in a comparative manner, the handling with open abdomen (OA) against closed abdomen (CA) in treatment of patients with severe peritonitis for traumatic lesion. MATERIAL AND METHODS: We carried out an observational, retrospective, longitudinal, and comparative study. It included patients managed with diagnosis severe peritonitis due to abdominal trauma between 1998 and 2000. They were divided into two groups, according to management with OA or CA. We compared age, sex, trauma type, severity of lesion, morbility and mortality. RESULTS: 12 patients were managed with OA, which presented longer hospitalization and 24 with CA who in turn presented a greater lesion severity. There were statistical differences in other parameters, including complications and mortality. However, patients managed with OA frequently presented more complications. DISCUSSION: OA does not improve morbility and mortality of patients, although they presented less severe lesions that those managed with CA.

Adjusted carbohydrate antigen 19-9. Correlation with histological grade in pancreatic adenocarcinoma.

BACKGROUND: The serum level of carbohydrate antigen 19-9 (CA 19-9) depends on the tumor size and differentiation grade. Jaundice can cause an elevation of serum CA 19-9, although the nature of this interaction is not fully understood. PATIENTS AND METHODS: This was a retrospective study of 26 patients with potentially resectable pancreatic adenocarcinoma. Serum CA 19-9 was correlated with the histological differentiation. CA 19-9 adjusted for serum bilirubin was determined and analyzed. RESULTS: No correlation between CA 19-9 and histological differentiation was determined (p>0.05). The median adjusted CA 19-9 level was significantly lower (p=0.01) in patients with normal biliary excretion than those with bilirubin levels >2 mg/dL. CONCLUSION: These data are consonant with the theory of a dual contribution to the serum CA 19-9 level from biliary obstruction and tumor cell synthesis.
