Subependymomas are benign intraventricular tumors with an indolent growth pattern, which are usually asymptomatic, and most commonly occur in the fourth and lateral ventricles. When symptomatic, subependymomas often obstruct critical portions of the cerebrospinal fluid (CSF) pathway, causing hydrocephalus, and range from 3 cm to 5 cm in size. We report a case of an unusually massive subependymoma of the lateral ventricles treated with subtotal resection, ventriculoperitoneal shunt, and post-surgical radiation. The clinical course, radiographic and pathologic characteristics of this massive intraventricular subependymoma are discussed, as well as the differential diagnosis of lateral ventricular masses and a review of the literature concerning subependymomas. 相似文献

Data from healthy children are needed to evaluate bone mineralisation during childhood. Whole body bone mineral content (BMC) and bone area were examined by dual energy x ray absorptiometry (Hologic 1000/W) in healthy girls (n = 201) and boys (n = 142) aged 5-19 years. Centile curves for bone area for age, BMC for age, bone area for height, and BMC for bone area were constructed using the LMS method. Bone mineral density calculated as BMC/bone area is not useful in children as it is significantly influenced by bone size. Instead, it is proposed that bone mineralisation is assessed in three steps: height for age, bone area for height, and BMC for bone area. These three steps correspond to three different causes of reduced bone mass: short bones, narrow bones, and light bones. 相似文献

The anti-emetic efficacy of a combination of tropisetron and dexamethasone
was studied in 33 patients who underwent bone marrow transplantation.
Another 50 patients receiving conventional anti-emetic therapies in bone
marrow transplantation served as control. On the first and second days of
preconditioning chemotherapy, 51% and 36% respectively of patients in the
tropisetron and dexamethasone group did not experience vomiting, compared
with only 12% and 10% of control group patients (P < 0.001). The mean
number of episodes of vomiting in the tropisetron and dexamethasone group
was also significantly lower than in the control group (0.97+/-1.65 vs
3.50+/-2.45 and 1.30+/-1.40 vs 4.44+/-2.91 respectively, both P <
0.001). Control of vomiting in the two groups was not significantly
different during days 3-6. Analysis of patients receiving busulfan and
cyclophosphamide as the preconditioning regimen still showed better
anti-emetic control in the tropisetron and dexamethasone group than in the
control group on the first two days of treatment (total control rate 33.3%
vs 6.5% and 44.4% vs 12.9% respectively, P < 0.001). Patients given
tropisetron and dexamethasone combination more frequently suffered from
dizziness and burning sensation of the chest. However, diarrhea and
extrapyramidal symptoms were the most frequent adverse effects seen after
using conventional anti-emetic combination. The combination of tropisetron
and dexamethasone was thus superior to conventional anti-emetic
combinations in preventing vomiting during preconditioning period of bone
marrow transplantation. The adverse effects of this combination were
minimal and well tolerated by patients.

BACKGROUND: The efficacy of the treatment of advanced gastric cancer is not
very good. The response rate to the original
etoposide--leucovorin--5-fluorouracil (ELF) treatment is 53% with tolerable
side effects. Whether increasing the dose intensity by prolonging the
duration of infusion with 5-fluorouracil (5-FU) and leucovorin (LV) from 3
to 5 days for advanced or metastatic gastric cancer patients would enhance
the efficacy but not increase side effects is still unknown. METHODS:
Thirty-six advanced or metastatic gastric cancer and chemotherapy-naive
patients with measurable or evaluable diseases were scheduled to receive
intravenous etoposide 100 mg/m2/day on days 2-4, LV 300 mg/m2/day
intravenously and 5-FU 500 mg/m2/day intravenously on days 1-5, every 4
weeks. All patients who received at least two courses of chemotherapy were
evaluated for tumor response, survival and response duration and toxicity
according to the WHO criteria. RESULTS: Thirteen patients showed a
response, including five with complete response (CR). The overall response
rate was 36% (95% confidence interval, CI, 20-52%) in the whole group and
46% (95% CI 28-66%) in the 28 patients with measurable disease. The median
progression-free interval and overall median survival time were 5 and 7
months, respectively. The most frequent toxicity was alopecia (grade I/II
56.3%). The incidence of grade III or greater myelosuppression was 5.9%. No
treatment-related death occurred. CONCLUSIONS: The efficacy of the modified
ELF by increasing the dosages of 5-FU and LV is not superior to the results
of the original regimen, yet it is a relatively safe and tolerable
combination regimen for advanced gastric cancer.

Growth monitoring in infancy is a useful tool for detecting growth disorders and failure to thrive. However, current weight charts do not monitor growth as such, they only identify infants whose weight centile is low and/or falling. A reference of conditional weight gain is described which compares an infant's current weight with that predicted from their previous weight, allowing for the fact that on average, light infants tend to grow faster than heavier infants. The reference, which expresses conditional weight gain as an SD score of centile, is based on the UK 1990 weight reference supplemented with correlation data on 223 infants from the Cambridge Infant Growth Study measured regularly between 4 weeks and 2 years of age. The reference is validated with data on 727 infants from the Newcastle Regional Health Authority database. The conditional reference provides a valid assessment of the weight gain of British infants, over time periods of four or more weeks, throughout the first two years of life. 相似文献

Measurements of oxygen consumption (VO2) were made during sleep in 10 patients with atopic dermatitis. Two groups of healthy children acted as controls. All subjects were studied in bed in an environmental temperature of 24-26 degrees C, and sleep was confirmed during continuous electroencephalographic monitoring. Mean (SD) values of VO2 in sleeping patients who were not scratching ranged from 4.0 (0.4) to 7.4 (0.7), which was not statistically significantly different from control values which ranged from 3.24 (0.3) to 5.56 (0.4). During scratching (while asleep), which occurred in nine out of 10 patients with atopic dermatitis, the mean values of VO2 ranged from 4.5 (0.04) to 10.4 (2.7), and this was significantly higher than the non-scratching patients and the control values. Scratching during sleep in children with atopic dermatitis is associated with increased VO2. 相似文献

Frequent deletion of chromosome 1p sequences in an aggressive histologic subtype of endometrial cancer 总被引:1,自引:0,他引:1

The molecular genetic events underlying endometrial tumorigenesis are
ill-defined at present. We have identified a region on the short arm of
chromosome 1 which is frequently deleted in endometrial cancers. The region
of deletion has been localized to bands 1p32-33. Deletion of 1p32-33 is
seen more frequently in cancers of the highly aggressive papillary serous
type than in cancers of the less-aggressive endometrioid type. These data
suggest the presence of a tumor suppressor gene on 1p32-33 which is
specifically involved in the development of endometrial cancers with poor
outcome.
