Ringed grafting for an abdominal aortic aneurysm in a 92-year-old patient: report of a case.

We report herein the case of a 92-year-old man with an abdominal aortic aneurysm who underwent successful surgical resection using a ringed graft. His postoperative course was uneventful, and he was discharged after 42 days, following which he attended the outpatient department twice a month for regular check-ups. He finally died of pneumonia which developed from an upper respiratory tract infection 6 months after his operation. Thus, surgical treatment should always be considered when an aneurysm is detected, even in very aged patients for whom the activities of daily living are possible.

Immunohistochemical and ultrastructural examination of histiocytosis X cells in pulmonary eosinophilic granuloma.

We describe histological, immunohistochemical, and ultrastructural findings in pulmonary eosinophilic granuloma (PEG) from three patients. The specimens were taken by open-lung biopsy. The lesions of the lung were composed of histiocytic cells, macrophages and eosinophils. The histiocytic cells reacted positively with anti-S-100 protein antibody. The histiocytic cells had various types of Birbeck granules in the cytoplasm. The histiocytic cells were histiocytosis X (HX) cells considered to be derived from Langerhans cells. Sporadic mitosis of HX cells was observed. Some HX cells had migrated from the lesions into the alveolar spaces through the alveolar cell layers. In the lesions of PEG, HX cells have self-reproduction and migration capability.

Idiopathic retroperitoneal fibrosis.

We treated a patient with idiopathic retroperitoneal fibrosis accompanied by right ureteral constriction. Pyelography, ureterography, and abdominal CT scan were pertinent diagnostics. Close collaboration between the surgeon and the urologist is required when attempting to treat such patients.

[A case report of successful immunochemotherapy of metastatic renal cell carcinoma using UFT and PSK].

The authors have monitored a case of renal cell carcinoma metastatic to the supraclavicular cavity over a twenty-year period following surgical removal of a cancerous kidney. The subject was a 67-year-old male who had his right kidney removed in 1963 because of renal cell carcinoma. In September of 1983, complaints of pain and an enlarged tumor in the left supraclavicular cavity during a physical examination led to a pathological diagnosis of clear cell carcinoma. Although chemotherapy using FT-207+ PSK was ineffective, there was a response to UFT+ PSK therapy which was deemed effective according to the criteria of Koyama and Saito. The findings suggested that UFT was effective in this case.

Intratumoral ethanol injection for malignant tracheobronchial lesions: a new bronchofiberscopic procedure.

We performed intratumoral ethanol injection via a flexible bronchofiberscope in 13 patients with malignant tracheobronchial lesions in order to evaluate its effects on airway dilatation and hemostasis. The results obtained are described below. Immediately after intratumoral injection of ethanol, bronchofiberscopic findings revealed that the tumor turned faintly white, there was a little regression of tumor, and a promising effect was demonstrated on patients with bleeding from tumors. The injected tumor turned necrotic within several days, and histological examination revealed no viable tumor cells in necrotic tissues. The histological anti-tumor effect of ethanol was also demonstrated in experiments with nude mice. This endoscopic treatment was very effective in polypoid tumor protruding into the tracheobronchial lumen, but ineffective in the case of compressed stenosis or obstruction. In conclusion, intratumoral injection of ethanol is considered to be a promising endoscopic treatment for malignant tracheobronchial lesions.

Thymolipoma simulating cardiomegaly: diagnostic usefulness of computed tomography.

We reported the case of a 46-year-old man with thymolipoma whose chest X-ray initially suggested cardiomegaly. Computed tomography (CT) clearly demonstrated the existence of a large mass adjoining the left ventricular wall in the mediastinum. CT also allowed estimation of the character of the mass including its size, extent, and consistency. At thoracotomy, the tumor was excised and thymolipoma was diagnosed histopathologically.

[Serum neuron-specific enolase as a marker of lung cancers].

Neuron-specific enolase (NSE) in sera of lung cancer patients was studied in order to evaluate its clinical significance as a tumor marker. The subjects included 15 normal volunteers, 13 cases without malignant neoplasms or neuronal diseases and 42 lung cancer cases. NSE was quantified by a double antibody radioimmunoassay. As one of the sera from normal volunteers and control patients showed an NSE content 10 ng/ml or more, values of 10 ng/ml or over were considered to be positive. Seventeen of 42 sera from lung cancer patients showed positive NSE levels. Histological evaluation revealed that the degrees of NSE positiveness for small cell carcinoma, large cell carcinoma, squamous cell carcinoma and adenocarcinoma were 73%, 50%, 33%, and 21%, respectively, and that all the positive cases except for one were confined to disease stages III or IV. The level of NSE in patients with 10 ng/ml or more before surgery decreased to within normal limits 1-2 weeks after surgery Localization of NSE could be confirmed immunohistologically in small cell carcinoma cells. In conclusion, NSE was considered to be very useful as a tumor marker of the lung, especially in small cell carcinoma for diagnosis and determination of disease extent and response to therapy, and also in non-small cell carcinoma for the evaluation of treatment effectiveness.

Sero-epizootiological study on swine influenza in a prefecture of Japan.

A total of 1799 swine sera collected in Toyama prefecture in the central part of Japan during the years 1978-82 were tested for antibody against swine influenza virus (SIV), A/New Jersey/8/76 (H1N1). A high prevalence of antibody was observed in the years after the severe epizootic of SI, 34.5% in 1979 and 51.7% in 1982. In other years, the percentages of positive sera were low and ranged from 1.7 to 12.4%. Regional variations were seen in relation to a small scale epizootic. No antibody to SIV was detected in any of the sera collected during the warm season. In the following dry and cold winter, however, a severe epizootic occurred among the swine populations.

[Clinical use of the serum level of immuno-suppressive acidic protein (IAP) in gastroenterological surgery].

Between September, 1981 and August, 1982, the IAP serum levels were measured in 151 patients to evaluate the correlation between these levels and the clinical spectrum. Pre- and postoperative IAP levels were also compared with the hospital course. Abnormally high IAP levels (greater than 450 micrograms/ml) were observed in malignant diseases, especially in patients with cancer of the pancreas, choledochus, gall-bladder, and esophagus. Of 193 patients, 81 revealed abnormal levels; 28 of these (34.6%) died during this study. The average of their survival time was 2.7 months. Nine of 81 patients (11.1%) experienced severe complications, but recovered. On the other hand, 112 patients with normal IAP levels had a relatively good hospital course; 9 (8%) died. None of the 112 patients experienced any complications. These results suggest that the IAP level may be a good tool in predicting clinical features and prognoses.
