| Odontophagia: | pain on swallowing |
| Dysphagia: | Pain on swallowing: Mechanical causes-affect large solids Motility disorders-intermittant, liquids |
| Changes in small intestine w aging | Decreased clearing of debris from small intestine to colon: -Gastric hypochlorhydria (low gastric acid) /jejunal diverticula with small intestinal bacterial overgrowth -Decreased vitamin D and Calcium absorption |
| with elderly, Colonic transit time is | normal, rectosigmoid transit is delayed, and Rectal contents are expelled more slowly |
| Dieulafoy's lesions | rupture of exposed submucosal artery that bleeds |
| This is more likely to be only colonic and to perforate... | Crohn's dz. |
| Fatigue, shortness of breath, angina are common elder symptoms in | -colon cancer -Adenomatous polyps become cancerous over 5-10 years |
| epigastric/back pain weight loss painless jaundice glucose intolerance malabsorption may be signs of | Pancreatic Cancer (CA 19-9 may aid in dx) |

| There is a 2-4 fold increase in plasma/serum levels of.... | Cytokines and other inflammatory mediators -increased fat -decreased sex steroids -smoking -subclinical infections -chronic diseases Aging may be associated with dysregulated cytokine response following stimulation |
| This occurs in 1/3 of pesons >60 increases absorption mightily of Penicillin G | achlorhydria (absent production of gastric acid) |
| Izoniacid in those over 50= | hepatotoxicity 2.3% |
| Fatalities are higher in elderly with this dz that presents as sudden onset of flu like/ fever transmitted between birds/ mosquitoes. CNS dz is rare | West Nile. Can also cause flaccid paralysis. |
| Ramsey-Hunt syndrome: | (of the geniculate ganglion) pain/vesicles external auditory meatus, loss of taste, ipsilateral facial paralysis Maxillary/mandibular trigeminal nerve involvement= intraoral lesions |
