[Angina-like chest pain due to gastric anisakiasis].

The chest pain is one of the most common reasons for consultation of the patients seen in the emergency services of hospitals. Still being the acute coronary syndrome one of the first causes to confirmed by its important repercussions, we do not have to forget other reasons. We report a case of acute anginalike chest pain due to gastric anisakiasis. The larvae of Anisakis in the gastric mucosa were found and extracted endoscopically. Gastric anisakiasis should be included in the differential diagnosis of acute chest pain.

[Aortic prosthetic endocarditis and periprosthetic abscess caused by Staphylococcus aureus].

Prosthetic endocarditis with annular abscess formation is a severe complication of cardiac valve replacement fortunately uncommon, though highly lethal. Increasing surgical experience and the high mortality with medical management have led to a widespread recommendation for early prosthetic replacement. We report a case of a 49 year old man with infective endocarditis due to Staphylococcus aureus in aortic ascendens prosthetic and aortic valve prosthetic complicated with periaortic abscess which was as successful treatment by drain of abscess without prosthetic replacement.

[Pulmonary interstitial disease due to hemochromatosis as a presenting sign of disease].

We present a patient with hemochromatosis whose first sign of disease was an accidental finding of interstitial patterns on a chest film and whose transbronchial biopsy showed traces of iron (Fe) in alveolar macrophages and septal matter. We then looked for deposits in other locations, finding Fe ([+]: 6.964 micrograms) in the dry weight of a cylindrical sample of liver tissue. A Medline search on CD-ROM for 1989 through May of 1994 revealed no references to similar cases.

[Localized tracheobronchial amyloidosis. The usefulness of computed tomography].

Tracheobronchial amyloidosis is the most common form of localized bronchopulmonary amyloidoses, although its diagnosis is rare in daily practice. We describe two new cases of localized tracheobronchial amyloidosis, one in the form of a single node and one diffuse. We discuss in particular the contribution of computed axial tomography, mainly for diagnosing the diffuse form, in which a finding of a thickened tracheobronchial wall and intraluminal nodes should lead to the suspicion of this entity. The treatment of choice in most cases is resection with an Nd-YAG laser.

[Spontaneous pneumothorax as the only initial manifestation of bronchogenic carcinoma].

We present the case of a patient with spontaneous pneumothorax associated to pulmonary epidermoid carcinoma, which was not radiologically visible after pulmonary reexpansion. Neither it was macroscopically detected in the first thoracotomy performed for the treatment of the pneumothorax, being diagnosed after the histological study of the resected blisters. The association between pneumothorax and lung cancer is very rare, especially in the absence of other radiological disorders suggesting neoplasia after the pulmonary reexpansion. In these cases, the diagnosis is extremely difficult and it must be always suspected in patients with spontaneous pneumothorax and risk factors for pulmonary cancer.

[Primary angiosarcoma of the spleen].

Primary spleen angiosarcoma is a malignant neoplasia based on vascular tissue and it is a rare tumor (65 cases published). The clinical aspects are obscure and the specific diagnosis is made by laparotomy. The prognosis is very poor in any case and survival isn't more than two years, whenever the spleen undergoes spontaneous rupture in which case the survival should be less than six months. The splenectomy before rupture could increase survival. Patients with or without metastatic disease may be treated by chemotherapy but with poor results. Radiotherapy is used for relief the pain produced for bone metastasis.

Clinical utility of hyaluronic acid values in serum and bronchoalveolar lavage fluid as tumor marker for bronchogenic carcinoma.

Various authors have proposed the use of hyaluronic acid (HA) as a tumor marker. In order to analyze its usefulness as a marker in bronchogenic carcinoma, the most common carcinoma in men, we determined the HA values in serum and bronchoalveolar lavage fluid (BAL). We performed prospective studies on two groups of patients: 81 diagnosed as having bronchial carcinoma and 34 with benign respiratory diseases. HA values were higher in patients with cancer than in those with benign diseases (serum: 79.8 ng/ml vs 63.7 ng/ml; BAL: 927 ng/mg vs 522 ng/mg). Also, the percentage of patients with levels exceeding the established cutoff was greater in the group with cancer than in the group with benign disease (serum: 24.6 vs 17.6; BAL: 25.3 vs 3). Statistically significant differences in these percentages were found in BAL (p<0.01). Patients with extended small cell carcinoma had higher HA values (p =0.04) than those with limited disease, and the percentage of patients with abnormal HA values was larger in the group with extended disease than in the group with limited disease (p = 0.004). The serial determinations of HA values in serum reflected the clinical evolution after treatment in 73% of the small cell carcinomas. Most of the patients with benign diseases whose HA values exceeded the cutoff level suffered from acute infectious dis-eases. Once these cases were excluded, the specificity of HA value determination in the diagnosis of carcinoma was very high (serum 96%, BAL 100%). The determination of HA levels in serum or BAL did not have any prognostic value in this study. We conclude that the HA levels in serum and BAL could be of interest as a tumor marker, especially in patients with small cell carcinoma.
