Persistent synchronous periodic discharges caused by anoxic encephalopathy due to cardiopulmonary arrest.

We report a patient with vegetative state induced by anoxic encephalopathy due to cardiopulmonary arrest who showed synchronous periodic discharges for a prolonged period. The patient was a 47-year-old man admitted to our hospital for depression, who suddenly developed cardiopulmonary arrest of unknown etiology, and entered chronic vegetative state as a result of anoxic encephalopathy. Electroencephalography (EEG) revealed that synchronous periodic discharges were present for up to 5 months. The wave pattern, periodicity and duration of appearance of synchronous periodic discharges were similar to those of synchronous periodic discharges in Creutzfeldt-Jakob disease (CJD). The periodicity of synchronous periodic discharges was gradually prolonged, with the course again similar to the discharges in CJD. The mechanism of occurrence is considered to be similar to that of synchronous periodic discharges in CJD.

[A study of infusional port re-insertion in patients with liver metastasis].

We evaluated the importance and usefulness of re-insertion of the intra-arterial infusion catheter in 10 patients with liver metastasis who showed problems in the catheter or system during intra-arterial infusion chemotherapy. The route of re-insertion was laparotomy-->left subclavian method in 3 patients, left subclavian-->left subclavian method in 5, and left subclavian-->femoral method in 2. The cause of re-insertion was dislocation in 5 patients, obstruction of the system in 4, and obstruction of CHA in 1. In the patients showing dislocation, re-insertion was performed after a mean of 4 months, and CEA improvement and direct effects evaluated by imaging techniques were marked, suggesting good indication. In the patients showing system obstruction or CHA obstruction, re-insertion was performed after a mean of 8.6 months, and CEA improvement and direct effects were less than those in the patients showing dislocation. Of the 10 patients who underwent re-insertion, 5 have survived to the present for 13-20 months (mean, 17 months). The prognosis of liver metastasis may be improved by active re-insertion of the intra-arterial infusion catheter.

Evaluation of a prototype for a reference platelet counter.

A semiautomated single channel aperture-impedance particle counter was developed as a prototype for a reference platelet count for assigning values to reference preparations used in automated blood cell counts. The instrument is equipped with sheath flow and an aperture orifice of 50 microns in diameter and 60 microns in length to eliminate non-axial flow and minimise coincidence errors. Use of fixed volume and red blood cell:platelet ratios obviate dilution errors. The counter was assessed in accordance with the International Committee for Standardization in Haematology protocol for evaluation of automated blood cell counters. The counter provided a high level of linearity and precision, accurate coincidence correction, controlled volume, stability and negligible carryover.

[A case of idiopathic fibrous mediastinitis with superior vena caval obstruction].

Uncommon case of superior vena caval obstruction secondary due to idiopathic fibrous mediastinitis was reported. A 38-year-old female was admitted in our hospital with the complaint of dyspnea and facial edema. Venography revealed occlusion of vena cava. Venous pressure showed 30 cmH2O in the external carotid vein. Mediastinal computed tomogram revealed no tumor but calcification in the anterior mediastinal fatty tissue. Therefore, with a 12 cm EPTFE, left brachiocephalic vein-right atrium bypass operation was performed. Facial edema was disappeared dramatically in early postoperative stage. She is uneventful 20 months after the operation.

[A case of accidental pneumatic rupture of the esophagus].

A case of pneumatic esophageal rupture secondary to distension from compressed air was reported. The patient, a 69-year-old man who was repairing an automobile tire suddenly exploded. The blast was directed into the open mouth. He was admitted to our hospital 12 hours after the onset with the complaint of chest pain and dyspnea. Subcutaneous emphysema was seen in the neck. The chest roentgenogram revealed a partial right hydropneumothorax. The diagnosis of esophageal rupture was established by Gastrographin swallowing study. Operation was performed 46 hours after the onset. Primary closure of the middle thoracic esophagus was judged to be impossible because of a 6 cm longitudinal laceration with contaminated pyothorax. Thereafter, total esophagectomy was indicated. Esophageal reconstruction using the pediculated gastric tube was performed throughout the retrosternal route. The leakage of esophagogastrostomy in the cervical area occurred in early postoperative stage. Re-esophagogastrostomy was successfully carried out 6 weeks after the first surgery. He is uneventful 6 months after the operation. We have not found any reports of surgical cases with pneumatic esophageal rupture treated by this approach in the literature.

[A case report of mediastinal cystic lymphangioma].

Mediastinal lymphangioma is very rare in the literature. A resected case of mediastinal cystic lymphangioma was reported. A 41-year-old man admitted to our hospital complaining of sore throat. A chest X-ray examination showed a large mediastinal mass on the right. At the right thoracotomy, a large cystic mass filled the anterior mediastinum and extended from the thoracic inlet to the posterior costophrenic angle. The cyst contained about 600 ml yellowish brown fluid and was adherent to the surrounding tissue, especially to the aorta and the left main bronchus. The resected tumor was 20 x 12 x 10 cm in size and 620 g in weight. Histological diagnosis was cystic lymphangioma. The patient is alive and well 26 months later, and there is no sign of recurrence of the tumor.

Coincidence correction in red blood cell counting.

A method has been developed for accurate correction of red blood cell count for coincidence in aperture-impedance electronic blood cell counters. It is based on extrapolation of the slope of regression of the counts which are obtained with sequential dilutions of the samples.

[Causes of death after an early gastric cancer operation].

From April, 1972 to December, 1984, 329 early gastric cancer case were operated on by this department. Results of these operations have revealed the following statistics: The 5-year survival rate of those with an m-cancer was 97.6% and for those with an sm-cancer, 92.6% and, the 10-year survival rate of m-cancer was 91.6% and sm-cancer, 89.9%, respectively. Twenty-nine postoperative deaths were recognized in this series, and the causes of death in each case have been analysed. Prophylactic measures to prevent postoperative death also are discussed.

[Four cases of male breast cancer including one synchronously combined with gastric cancer].

Four men with primary breast cancer were seen between 1972 and 1985 at the Sasebo Municipal Hospital. They were admitted complaining of breast mass and/or bloody nipple discharge. There was no delay between the onset of symptoms and seeking medical advice. They had relatively early stages of disease (three patients had stage I and one had stage II). All patients were treated by modified radical or radical mastectomy. Histopathological study revealed ductal carcinomas and no lymph node metastasis in all patients. Multiple bone metastasis and death occurred in one case. One patient (61 years old) had two separate synchronous primary cancers of the breast and stomach, which is very uncommon.
