[Q]: Abstract: Seventy-five patients, 80-90 years old, each having approximately three associated diseases, underwent a total of 104 gastrointestinal endoscopies. Of these, 73 were upper (29 emergencies) and 31 lower endoscopies (21 were rigid sigmoidoscopies). There were two very mild short-lived complications; vomiting and bleeding. We found 16 gastric ulcers, 16 duodenal or pyloric ulcers, and 11 cases of esophagitis. Bleeding duodenal (8) or gastric (4) ulcers and polyps or malignant tumors (7) were seen less often. In 34 of 68 lesions the endoscopic and x-ray findings were the same. In the other 34 there were 10 endoscopic failures to identify colonic diverticula, hiatus hernia, and gastroesophageal reflux that were seen radiologically. In 24 patients, diagnoses were not made radiologically, but were recognized at endoscopy. The safety and accuracy of endoscopy in the old and sick does not differ from that in younger patients.

[Q]: Abstract: Abnormalities of coagulation and fibrinolysis in 12 head-injured patients were studied in early (within 24 hours of onset) and late (10th to 17th day after onset) stages. alpha 2 Plasmin inhibitor (alpha 2PI), antithrombin III (ATIII), and fibrinopeptide A (FPA) and B beta 15-42 (FPB beta) were measured in particular, in addition to the usual tests (platelet count (PLT), prothrombin time (PT), partial thromboplastin time, fibrinogen, and fibrin/fibrinogen degradation products (FDP)). alpha 2PI was abnormally lower, and FPA and FPB beta were much higher; fibrinogen and ATIII were moderately lower in the early stage than in the late stage in 6 head-injured patients with postoperative intracranial hemorrhage. alpha 2PI, ATIII, and fibrinogen were moderately lower and FPA was moderately higher in the early stage than in the late stage in 6 head-injured patients without postoperative intracranial hemorrhage. PLT and fibrinogen were lower, alpha 2PI was much lower, and FPA was much higher in the 6 patients with postoperative intracranial hemorrhage than in the 6 patients without postoperative intracranial hemorrhage. One patient with acute epidural and subdural hematomas had recurrent postoperative intracerebral hematoma twice. This recurrent hemorrhage was due to disseminated intravascular coagulation (DIC) caused by primary brain damage and was associated with extremely high FPA and FPB beta levels and abnormally low alpha 2PI and PLT. Fresh-frozen plasma and intravenous low-dose heparin were administered after the two recurrent hemorrhages, after which FPA and FPB beta normalized immediately, although other screening tests showed only gradual improvement.(ABSTRACT TRUNCATED AT 250 WORDS)

[Q]: Abstract: In a consecutive series of patients with knee complaints, tibial rotation consistently affected the interpretation of the Lachman test (passive anterior tibial translation in slight knee flexion). To perform the Lachman test correctly, the anterior tibial force must be applied posteromedially on the proximal tibia. This is best achieved by having the leg under examination on the same side of the bed as the examiner, and with slight external tibial rotation. Reaching across the bed to examine either leg can create either false positive or false negative Lachman results due to inadvertent tibial rotation (internal tibial rotation decreases translation) and inaccurate comparisons of the injured and normal legs. The importance of tibial rotation must be recognized if the Lachman test is to be used reliably and with maximum sensitivity.
