[Total gastrectomy in cancer of the stomach (author's transl)].

143 cases of total gastrectomy in cancer of the stomach from 1961 to 1976 are reported. A satisfactory function is observed in long living patients having a substitute stomach formation ("Ringplastik") as well as in those having been operated according to the method of Graham. The rare occurrence of reflux oesophagitis is attributed to a special technique for anastomosis.

Evaluation of left ventricular performance in acutely ill patients with chronic obstructive lung disease.

Among 28 patients with chronic obstructive pulmonary disease (COPD) with increasing dyspnea, the resting mean pulmonary arterial wedge pressure was elevated (greater than 12mm Hg) in 4 and became abnormal with exercise in 3 other subjects. Stroke volume index was reduced (less than 36 ml/beat/M2) in 16 of 26 patients (62 percent). The resting pre-ejection period index was prolonged (greater than 144 msec) in 17 patients (65 percent), while the left ventricular (LV) ejection time index was reduced (less than 408 msec) in 23 patients (88 percent). The ratio of the pre-ejection period to the LV ejection time was within the normal range (0.309 to 0.381) in only 3 of 26 patients (12 percent). Echocardiographic measurements of LV function were normal in nine patients, seven of whom had one or more abnormal values for systolic time intervals (STIs). These data suggest that reduced LV filing results in abnormal values for STIs in patients with COPD, and therefore that in such patients STIs are not accurate indices of LV function.

The relationship between articular cartilage degeneration and bone changes of the first metatarsophalangeal joint.

Plain-film radiography is commonly used in the assessment of joints affected by osteoarthritis. It has been shown that the condition of articular cartilage in the knee, when grossly assessed, does not always correlate well to the radiographic evaluation of the joint. The aim of this study was to determine whether a relationship existed between the radiographic appearance of the subchondral bone and the morphological condition of the articular cartilage surfaces of the first metatarsophalangeal joint. Forty-nine pairs of cadaveric metatarsals and their respective proximal phalanges were studied in order to determine the correlation between articular cartilage degeneration and radiographic grade using a modified Kellgren-Lawrence scale. The relationship between cartilage degeneration and age, gender, osteophytes, metatarsal length, and measured angles (proximal articular set angle, distal articular set angle, intermetatarsal angle) was also investigated. It was found that there was a significant correlation between radiographic grade and cartilage degeneration on both the metatarsal head and the base of the proximal phalange (r2 = .2038 and .1733, respectively). However, while useful in the clinical setting, bony changes of the first metatarsophalangeal joint, as seen radiographically, fail to provide a full representation of the level of cartilage degeneration on the articular surfaces of this joint.
