The omental sandwich reconstruction for a full-thickness cheek defect.

We present a case in which a large full-thickness cheek defect was successfully repaired in one stage by the "omental sandwich technique." We transferred the omentum as a free flap, anastomosing the middle omental vessels with the end stumps of the gastroepiploic vessels after they had been brought to the neck through a subcutaneous tunnel. Skin grafts were applied then on both sides of the revascularized omentum.

Primary adenosquamous carcinoma of the stomach: experience of 11 cases and its clinical analysis.

1) During the last 10 years, 11 cases of primary adenosquamous carcinoma of the stomach were operated on. 2) Histologically, the specimens from the stomach showed adenocarcinoma with squamous differentiation in all the cases. 3) All the patients but 1 were males and their average age was 61.2 years. 4) The duration of illness prior to treatment was relatively long period of time and the chief complaints in over half of the patients were abdominal pain. 5) Eight cases showed metastases at the time of operation. Metastasis to the regional lymph nodes was observed in 8 cases and the squamous element was present in 5 of these cases. 6) There was no operative death. Followup study was made in 9 cases. Only 2 are still alive and the remaining 7 died of recurrence. The length of survival averaged 10.7 months.

Computational reconstruction of body surfact isopotential maps in myocardial infarction: comparison between nontransmural and transmural infarction.

The relationship between the lack of electromotive force in myocardial infarction and body surface potential distribution was investigated on maps reconstructed from a simulated heart model and transfer impedance vectors of human torso model. The heart model, a cluster of 3-mm cubic blocks, was stored in the memory of a computer. Transfer impedance vectors between 81 lead points on the human torso model and 392 positions covering ventricular areas in the torso were measure. Body surface potential values were calculated mathematically by summing up scalar products between the electromotive force of the heart model and the measured transfer impedance vectors. Thus, reconstructed maps changed in their patterns with the alternation in lacation and/or extent of infarcted region in the heart model. In particular, the appearance of the abnormal potential minimum, which projects the infarcted region in the heart model onto the torso surface, was characteristic in both transmural and subendocardial infarction. In addition, delayed activation in the intact layer of the epicardium overlying the infarcted region produced a potential maximum on the same place as the abnormal potential minimum appeared previously.

Serum lipid and lipoprotein abnormalities in major clinical entities of renal disease.

More than half of the patients with glomerulonephritis, nephrotic syndrome and renovascular hypertension showed obviously abnormal profiles of serum lipoproteins (Lps). The abnormal profiles returned to normal or near-normal when the disease was ameliorated or corrected surgically. A unique Lp profile (broad midband pattern, BMP) was observed in approximately 89% of uremic patients on hemodialysis therapy. The results of the current investigations indicated that the BMP could probably be formed by the accumulation of catabolic remnants of VLDL.

Body surface isopotential maps. Clinical application to the diagnosis of myocardial infarction.

This paper is a review of recent work relating body surface isopotential maps to the detection of the site and extent of myocardial infarction in cases which are either indetectable or difficult to diagnose through the use of standard 12 lead ECGs. According to the difference of the site and extent of myocardial infarction, the characteristic maps are obtained. Through the use of body surface isopotential maps, the significant clinical information may be obtained in a number of cases, and we can do better with mapping than without it in the evaluation of patients with myocardial infarction.
