Surgical treatment of temporal lobe epilepsy: clinical, radiological, and histopathological findings in 178 patients. Cholinergic augmentation with donepezil enhances recovery in short-term memory and sustained attention after traumatic brain injury. The first known case of this disease occurred in a 51-yearold woman, Auguste D, who was initially seen by Alois Alzheimer in 1901 at the Frankfurt State Asylum. Alzheimer subsequently moved to Munich to work with Kraepelin and, after Auguste D died, he presented his findings on 3 November 1906 at the 37th annual meeting of the Southwest German Psychiatrists in Tubingen; these findings were published in 1907 (Alzheimer 1907). Alzheimer himself was diffident about lending his name to the disease, and it was only at the urging of Kraepelin that he agreed, thus giving us now the most famous of all medical eponyms (Amaducci et al. Clinical features Although onsets in early adulthood may occur, the vast majority of cases present gradually and insidiously past the age of 50 years. In the vast majority of cases, the presentation is with a progressively worsening amnesia; in most of these cases, the amnesia is joined by a gradually progressive personality change. With amnesia as the presenting feature, patients gradually become more and more forgetful (Bowler et al. Over time, as this anterograde component of the amnesia grows more profound, it is typically joined by a progressively worsening retrograde component: patients may forget where they have worked, the names of their children, the fact that they have been married, where they went to high school, etc. Personality change may take various forms: apathy, indifference, and withdrawal are most common. Patients may also develop a frontal lobe syndrome, with coarseness, impulsivity, and disinhibition (Mega et al. Even more rarely, the presentation may be with a gradually worsening apraxia (Ross et al. With gradual progression, further cognitive deficits accrue to eventually complete the clinical syndrome of dementia. The mild stage is characterized primarily by cognitive deficits: in addition to the amnesia, one also finds a decrease in abstracting and calculating abilities; there is also often a degree of anomia and apraxia. In the moderate stage, cognitive ability deteriorates further and speech may deteriorate into a fluent aphasia (Faber-Langendoen et al. In the severe stage there is a profound cognitive deficit, and patients are often totally dependent on others for their care; mutism may occur, or there may be echolalia or palilalia. In addition to cognitive deficits most patients will also develop mood changes and psychotic symptoms, generally during the moderate stage. Mood changes may include depression, apathy, anxiety and irritability, agitation, and euphoria (Mega et al. Depressive symptoms are fairly common, with prevalence figures noted of 14 percent (Klatka et al. The severity of the depression varies from mild to that encountered in the depressive episodes of a major depression (Migliorelli et al. Apathy may accompany depression, but it may also be seen in a pure form in roughly one-third of all patients (Starkstein et al. Anxiety and irritability are about as common as depression, being found in a little less than one-half of patients (Litvan et al. Psychotic symptoms include hallucinations, either visual or auditory, and delusions. They may insist that things have been stolen or taken from them, and they may be terrified that family members are actually imposters who have come to annoy or torment them; some may insist that someone, perhaps someone malevolent, is in fact hiding in the house, perhaps in the attic or the cellar. In some cases, misidentification may be quite remarkable, and patients may insist that their own reflection in the mirror is in fact not them (Forstl et al. Anosognosia is seen in a minority early on, but becomes common with disease progression (Starkstein et al. Parkinsonism may be seen late in the course in a minority of cases, being typically characterized by rigidity and bradykinesia, with tremor being relatively rare (Clark et al. Early on in the course, the degree of this change may still be within the broadly defined limits of normal for the elderly population, but with progression, the changes become quite pronounced, as illustrated in Figures 8. The electroencephalogram is typically normal in mild disease; however, with progression generalized theta, and eventually delta, slowing appears.
Although the infection is nearly always asymptomatic blood pressure medication iso lisinopril 2.5 mg mastercard, in some cases muscular weakness blood pressure medication with food 5 mg lisinopril with visa, muscular pain pulse pressure from blood pressure purchase lisinopril 5 mg amex, myositis blood pressure medication you can drink alcohol discount 5 mg lisinopril amex, periarteritis, and subcutaneous tumefaction have been observed. However, in none of these cases was there conclusive proof that the muscular cysts were the definite cause of the clinical symptoms. The Disease in Animals: There are several species of sarcocysts in nonhuman mammals, which can occasionally cause intestinal or systemic disease. Source of Infection and Mode of Transmission: the source of infection for human intestinal sarcocystosis is beef or pork containing mature sarcocysts. Only the bradyzoites, which appear about two and a half months after infection of the intermediate host, are infective for the definitive host. The mode of transmission is through the ingestion of raw or undercooked infected meat. The mode of transmission is through contamination of pastures or feedlots with feces and the eventual ingestion thereof by cattle or swine. The sarcocysts have strict host specificity, so it is clear that other vertebrate species are not directly involved in transmission. Some authors have suggested that the reports of human cases of sarcosporidia are based on erroneous diagnoses. Taking into account the morphology of the sarcocysts, Beaver (1979) and Kan and Pathmanathan (1991) have suggested that man might be an aberrant host of sarcocysts that normally infect the musculature of monkeys. The relative frequency of the infection in areas where there are large numbers of monkeys gives some credence to this hypothesis. Diagnosis: Human intestinal sarcocystosis can be diagnosed by confirming the presence of oocysts or mature sporocysts in feces starting on day 9 or 10 following the ingestion of infected meat. Muscular cysts in cattle and swine are found along the length of the muscle fiber and are whitish in color, often microscopic in size, and have the shape of a long cylinder. The cyst wall forms internal septa that separate the bradyzoites into banana-shaped compartments measuring 6 to 20 µm by 4 to 9 µm (Gorman, 1984). The cysts are found most often in the cardiac muscle, esophagus, and diaphragm of adult cattle and swine. They can be observed by trichinoscopy and, more effectively, by microscopy following tryptic digestion of the infected meat. The sarcocysts are similar to those in man, but they can sometimes be as long as 5 cm and are visible to the naked eye. Control: Cattle or swine should be prevented from ingesting infected human feces, and humans should avoid eating raw or undercooked meat. In the first case, measures should be taken to properly dispose of human waste in rural settings where there are large numbers of cattle and swine. Except in areas where there are high rates of human infection, it is probably not necessary to treat infected individuals in order to reduce contamination of the environment. The population should be educated about the risk of infection when raw meat is consumed, and veterinary inspection of slaughterhouses should be improved. In addition, it can, and usually does, take advantage of an intermediate host, which may be any of some 200 species of vertebrates. They then multiply sexually by gametogony and produce immature oocysts that cause the host cells to rupture, after which they are eventually evacuated in the feces. The cat sheds the oocytes for a period of 1 or 2 weeks, and then the cat develops immunity. Outside the host, the oocysts mature in 1 to 5 days, depending on the temperature and humidity of the environment, at which point they form sporulated oocysts (11 µm by 13 µm), each containing two sporozoites (6 µm by 8 µm) without a Stieda body and each of the latter containing four more sporozoites (2 µm by 68 µm) inside it (Dubey and Beattie, 1988). In the intermediate host, which can include man and the cat, parasites are released in the small intestine and invade the epithelial cells, where they multiply until they rupture the cells. They are then disseminated by the lymphatic system or the bloodstream, either as free forms or inside macrophages or leukocytes. Although most of the parasites are captured by the lymph nodes, they can also be found inside macrophages or monocytes, and in some cases they bypass the lymph nodes and spread throughout the rest of the organism. They are very active, and their cycles of invasion, multiplication, and cell rupture continue for one to two weeks, until the host develops a degree of immunity. The bradyzoites accumulate in the cytoplasm of the parasitized cells and encase themselves in a membrane, forming a cyst. These forms can parasitize any nucleated cell, but tachyzoites show a preference for macrophages and monocytes, while bradyzoites are seen more often in muscle and nerve tissue. Occurrence in Man: the infection is very common, but the clinical disease is relatively rare.

Thickened wall, appendicolith, fat stranding, periappendiceal fluid, phlegmon, abscess Generally, emergent appendectomy is desirable. When an appendiceal abscess develops, percutaneous drainage followed by elective appendectomy several weeks later is appropriate. When the patient presents several days after the onset of symptoms, in which case a phlegmon has most likely developed. In this case, treatment should be with broadspectrum antimicrobial agents, followed months later by elective appendectomy. Adenomatous (tubular, villous, or tubulovillous, sessile), hamartomatous, hyperplastic, and inflammatory Adenomatous polyp Which type of polyp is precancerous? If a polyp is found at flexible sigmoidoscopy, there is a 10%15% chance of finding a more proximal synchronous polyp; therefore, colonoscopy is recommended. What is the screening interval in a patient with average risk who has a normal colonoscopy? Chapter 5 / Gastroenterology 259 For an average-risk patient with only a few benign adenomatous polyps, which were completely removed during a screening colonoscopy, when should the next surveillance colonoscopy be performed? What polyp features influence the likelihood of developing carcinoma within an adenomatous polyp? The polyp size, the degree of villous architecture, and the severity of dysplasia within the polyp It is the second most common cancer overall in the United States, with a 6% lifetime risk in the general population. Weight loss is seen primarily when bowel obstruction prevents people from eating, or when metastatic disease exists (usually hepatic metastases). Approximately two-thirds of all colon cancers (and adenomatous polyps) are within reach of the flexible sigmoidoscope. Apple-core lesions usually encircle the bowel and cause bleeding and early obstruction. Because of the increased compliance of the right colon, and because its contents are still semiliquid, obstruction usually occurs with advanced lesions. Still requires bowel preparation, involves large doses of radiation, will not pick up adenomas 5 mm, and you run the risk of missing large sessile lesions, which are often malignant. It is not diagnostic and is used only to monitor for recurrence after treatment or metastatic spread. It is sometimes used for the initial diagnosis of polyps or mass lesions; however, about one-third of tumors and polyps are missed, particularly if smaller than 1 cm. Additional rare epithelial tumors include squamous cell carcinoma, adenosquamous carcinoma, and undifferentiated carcinoma. Tumor invades through the muscularis mucosa into submucosa but extends no farther than the muscularis propria. High-grade tumor and the presence of obstruction or perforation Individuals with tumors involving the rectum or the rectosigmoid colon have a lower 5-year survival than those with cancers detected elsewhere in the large bowel. Hereditary polyposis syndromes in which numerous adenomatous polyps develop, and there is a very high risk of cancer. Desmoid tumors, osteomas (of the mandible, skull, and long bones), congenital hypertrophy of the retinal pigmented epithelium, dental abnormalities, and epidermoid cysts. Physical examination, endoscopy, and radiographic studies allow discovery of physical findings. The risk of cancer in the duodenum and ampulla of Vater region is particularly high. Proctocolectomy is recommended for patients who have developed multiple colonic polyps, or for people who are found to have the genetic defect.
