摘要:

A review of the recent Mayo Clinic experience with stroke in children having cerebral angiography revealed five patients with moyamoya disease. The disease commonly presents as recurrent strokes and only rarely as a seizure disorder. The angiographic pattern suggests that the telangiectasia characteristic of this condition represents normally present dilated vessels.

摘要:

The results of this study (1969–1971) confirm previous findings that incidence rates for hemolytic and group A streptococci in Nashville school children fluctuate sporadically. During these two years, there was a significant decrease in streptococcal incidence and in typability of group A streptococci. A positive throat culture was not associated significantly more often with symptoms of an infection of the upper respiratory tract than when symptoms were absent. The larger the number of group A streptococci present in the throat culture, the more likely was a streptococcal antibody increase to occur. Nevertheless, some children with small numbers of group A streptococci had an antibody increase, and the degree of positivity of the throat culture was not a very accurate indication of whether an antibody response would occur. Epidemiologic factors such as age, sex, race, or crowding in the home did not seem to play a highly significant role in rates. Seasonal influences were marked in 1969–1970 but not in 1970–1971. Regarding socioeconomic background, the rates were consistently lower in Clemons school, which serves a predominantly black neighborhood of higher socioeconomic level, than in the other two schools. Our findings confirm that the incidence of acquisition of the hemolytic streptococcus is a continually changing, dynamic process among school children.

摘要:

Radiographic evaluation of 65 patients with disseminated carcinoma of the prostate shows that 8% demonstrated resolution of metastatic deposits after palliative transurethral resection and/or estrogen or castration therapy. The increased effectiveness of therapy and the improved management of patients are reflected in longer survival. Roentgenographic evidence of increasing sclerosis of osteoblastic metastases of carcinoma of the prostate indicates that the rate of bone repair exceeds the rate of bone destruction, and is not necessarily an indication of progression of the disease. Increasing prominence of blastic bony lesions is not a poor prognostic sign; several patients showing it were symptom-free and survived for long periods. Sclerotization of lytic deposits is definitely a good prognostic sign of treatment and represents “healing change” within involved bone.

摘要:

A double-blind, prospective study over a 12-month period evaluated the effectiveness of cefazolin and cephalexin in reducing infection and morbidity in private patients undergoing vaginal and abdominal hysterectomy. Prophylactic antibiotics reduced febrile morbidity from 74.4% to 20.8% in the vaginal group and from 46.2% to 24.0% in the abdominal group. Serious postoperative infections such as pelvic abscess, pelvic cellulitis and abdominal wound infection were reduced from 11.5% to 0% in the abdominal group and from 32.6% to 2.1% in the vaginal group. The use of prophylactic antibiotics was of benefit in the perimenopausal and postmenopausal patient, as well as in the premenopausal patient, although, in some categories, the numbers were too small to be statistically significant.

摘要:

Ultrasound can provide significant information in the fields of obstetrics and gynecology. Fetal presentation, presence of multiple gestation, and gross fetal abnormalities are easily determined. Measurement of the biparietal diameter correlates more closely with gestational age than does use of the fetogram. In addition, there is no evidence of fetal toxicity by this method, and the placenta is easily located. Ultrasound is the preferred method for diagnosis of placenta previa. Abnormalities of the early gestational period including missed abortion, ectopic pregnancy, and molar pregnancy also can be diagnosed by ultrasound. The cystic or solid nature of pelvic masses can be assessed as well as their relationship to the uterus and adnexa.
