the artificial sphincter (as-800). experience in children and young adults.	from reviewing our experience in the application of the as-800 sphincter for the management of incontinence in children, we conclude that implantation is indicated after conservative and less invasive therapy has been attempted. the bladder neck is the site of choice for cuff placement in children. primary deactivation and moderate or low reservoir pressures (61 to 70 and 71 to 80 cm h2o) are indicated, especially in patients with previous bladder neck surgery or an inadvertent bladder neck inju ...	2010	2916269

physical disability: the role of the physical scientist in the health service. a report of the institute of physical sciences in medicine.	the report of the royal college of physicians on physical disability in 1986 and beyond gives details of a medical disability service to redress the present imbalance in the provisions for the physically disabled. an integral part of this service should be the provision of adequate scientific and technical resources, which could be established by making four or five new medical physics and clinical engineering appointments annually in each region for the next ten years.	2010	2966028
post-mastectomy breast reconstruction using the inflatable tissue expander.	breast reconstruction following mastectomy has previously relied on the insertion of a silicone gel implant or the use of a myocutaneous flap. we report the use of an innovation, the inflatable tissue expander, for both immediate and delayed breast reconstruction in 26 patients where soft tissue cover was inadequate to permit the use of the silicone implant. by serial inflation of the tissue expander with saline, sufficient tissue cover was achieved for a second operative placement of a silicone ...	2010	3768654
pyocele of scrotum: consequence of spontaneous rupture of testicular abscess.	we report 2 cases of spontaneous rupture of the testis secondary to suppurative epididymo-orchitis. both cases presented with pyoceles and were treated conservatively by scrotal incision and drainage of the pyoceles. this prolonged hospital stay and increased morbidity, since both patients ultimately required orchiectomy. we believe that a pyocele is an indication for prompt surgical exploration, and if the testis is ruptured, an orchiectomy should be done.	2010	2929065

limitations of 131i-mibg scintigraphy in locating pheochromocytomas.	131i-metaiodobenzylguanidine (131i-mibg) scintigraphy for the location of pheochromocytomas has proved to be a major advance in patient management. in combination with computerized tomographic scanning, nearly all pheochromocytomas can be located before surgery and invasive investigations are now indicated only in exceptional cases. however, there are still lessons to be learned concerning the optimal administration and interpretation of 131i-mibg scintigraphy. with careful attention to detail a ...	2010	2861667

connective tissue responses in blacks in relation to disease: further observations.	additional information is presented in support of the hypothesis (polednak: am. j. phys. anthropol. 41:49-58, 1974) that in some black populations certain connective-tissue responses, which are involved in protection against infection and repair after injury, also may predispose to specific chronic diseases. these diseases include some autoimmune disorders (i.e., systemic lupus erythematosus, sarcoidosis, and scleroderma) and various benign and malignant tumors involving connective-tissue cells. ...	2010	3322033

fluvoxamine in the treatment of the older depressed patient; double-blind, placebo-controlled data.	fluvoxamine was given in placebo-controlled trials to 33 severely depressed patients of between 60 and 71 years, 29 received imipramine and 14 placebo. at week 4 of treatment fluvoxamine and imipramine were superior to placebo on the hamd and cgi scales (p less than 0.05). there was indication of an earlier onset of antidepressant activity in the fluvoxamine group. there was no evidence of systematic changes in laboratory variables in any treatment group. fluvoxamine and placebo had similar effe ...	2011	3104446
spatial phase dependence and the role of motion detection in monocular and dichoptic forward masking.	contrast thresholds for briefly flashed gratings were measured by the quest procedure, under conditions of forward masking by gratings of the same spatial frequency (usually 1 c/deg). low-contrast masks reduced threshold at short onset asynchronies (0 to 50 msec), while higher contrasts raised threshold over a broader temporal range (0 to 100-140 msec). both effects depended on the spatial phase relation, but in different ways. threshold reduction at 0- +/- 90 deg phases probably arises from spa ...	2011	3253991

secretory process of salivary glands of female amblyomma cajennense (acari: ixodidae) ticks fed on resistant rabbits.	ticks have great economic and health importance since infested animals have reduced milk and meat production, and, besides that, they are expensive ectoparasites to control. while feeding, ticks can transmit to their hosts a large amount of pathogens, including rickettsia rickettsii responsible for the "spotted fever" or "fever of the mountains." it is known that animals infested with ticks or artificially immunized with their salivary gland extracts develop resistance, which is related to a dec ...	2011	20711802
experimental infection of rhipicephalus sanguineus ticks with the bacterium rickettsia rickettsii, using experimentally infected dogs.	we evaluated if rickettsia rickettsii-experimentally infected dogs could serve as amplifier hosts for hipicephalus sanguineus ticks. in addition, we checked if rh. sanguineus ticks that acquired ri. rickettsii from dogs could transmit the bacterium to susceptible hosts (vector competence), and if these ticks could maintain the bacterium by transstadial and transovarial transmissions. uninfected larvae, nymphs, and adults of rh. sanguineus were allowed to feed upon three groups of dogs: groups 1 ...	2011	20569011
