ABSTRACT
Objective To evaluate the spontaneous closure of isolated fetal ventricular septal defect (VSD) in uterus and follow-up during the first year after birth using echocardiography. Methods From January 2012 to June 2017, 51 cases with isolated VSD without chromosome abnormality were observed in uterus and followed-up during the first year after birth using echocardiography in People's Hospital of Daxing District in Beijing City. The location, size, closure time of the VSD were recorded. The closure rate was calculated. The closure rate of the VSD in utero and in infant during the first year after birth were compared by Fisher exact probability method. The relation of closure rate and location and size were also analyzed (P＜0.05 was significant). The comparison between groups one by one were performed by Fisher exact probability method (P＜0.0167 was significant). Results In 51cases, 30 had perimembranous VSD, 16 with muscular VSD and 5 with infundibular VSD. In 20 closure cases (39.2%), 9 fetuses (17.6%) were closed in utero, 11 infants (21.6%) were closed during the first year after birth. There was no significant difference between the closure rate of the VSD in utero and the closure rate of VSD in infant during the first year after birth (P=0.804). In 16 with muscular VSD, 11 cases (68.8%) were closed, in whom 4 fetuses (25.0%) were closed in utero and 7 infants (43.8%) were closed during the first year after birth. In 30 perimembranous VSD, 9 cases (30.0%) were closed, in whom 5 fetuses (16.7%) were closed in utero and 4 infants (13.3%) were closed during the first year after birth. The closure rate of muscular VSD were significant higher than that of the closure rate of perimembranous VSD and infundibular VSD (P=0.007, 0.012). There were no significant difference between the closure rate of the perimembranous VSD and infundibular VSD (P=0.297). The infundibular VSD remained unclosed in all cases. In 35 cases with VSD≤3.0 mm, 19 cases (54.3%) were closed, in whom 9 fetuses (25.7%) were closed in utero and 10 infants (28.6%) were closed during the first year after birth. There was 1 closure case (7.6%) with VSD of 3.1-5.0 mm. The closure rate of VSD≤3.0 mm were significant higher than that of the VSD of 3.1-5.0 mm and the VSD＞5.0 mm (P=0.007, 0.013). There was no significant difference between the closure rate of the VSD of 3.1-5.0 mm and VSD＞5.0 mm (P=1.0). The VSD＞5.0 mm remained unclosed in all cases. Conclusions Isolated VSD has a high closure rate in utero and during the first year after birth. Echocardiography was a reliable method in diagnosis and follow-up of isolated VSD.
ABSTRACT
@#Objective To identify the risk factors for osteoporosis in patients with hemiplegia. Methods The total body bone mineral density (BMD) of 366 patients with hemiplegia in the stage of rehabilitation was measured with dual-energy X-ray absorptiometry. The data of the patients were analyzed with multiple logistic regressions. Results The incidence of osteoporosis was 15.3 % (56/366) in the cohort. ≥60 years old (OR=5.434, 95% CI:2.734～10.801), duration of disease (OR=1.046, 95% CI:1.013～1.080), body mass index (BMI) (OR=0.746,95% CI:0.622～0.840),ADL level (OR=0.618, 95% CI: 0.444～0.858) were independently correlated with osteoporosis in patients with hemiplegia. Conclusion Patients with hemiplegia in the stage of rehabilitation were at a high risk of osteoporosis. Aged over 60 years old, lower BMI, longer duration of disease and ADL level were independent risk factors for osteoporosis, which called for supervision and prophylaxis on osteoporosis.
ABSTRACT
@#Objective To investigate the changes of bone mineral density (BMD) and bone mass and the influencing factors in patients with hemiplegia.Methods The total BMD, bone mass, lean mass and fat mass of 366 patients (313 stroke cases and 53 TBI cases) with hemiplegia were tested by dual-energy X-ray absorptiometry, as well as the clinical features of all patients, were studied.Results The bone masses in the paretic side (upper limb, lower limb and trunk) decreased significantly compared with nonparetic side ( P<0.01); the differences of bone masses (%) in upper limb, lower limb and trunk between paretic and nonparetic side decreased with duration of disease or trauma ( P<0.01). The multivariable stepwise regression analyses showed that the total bone mass and total BMD were negatively correlated with age and duration of disease significantly (all P<0.01), and positively correlated with body mass index (BMI) significantly ( P<0.01), the total BMD was also positively correlated with lean mass ( P<0.01) and ADL level ( P<0.05).Conclusion The bone mass deceases in the paretic side significantly, and gets worse with the duration of disease. Age, duration of disease or trauma and BMI influence total BMD and bone mass; in addition, total BMD is correlated with total lean mass and ADL level.
ABSTRACT
@# ObjectiveTo evaluate the value of endoscopy in the diagnosis of biliary tract roundworm disease.Methods32 cases of biliary tract roundworm diseases were diagnosed and treated with fibre (electron) stomach duodenum endoscopy and fibre biliary tract endoscopy under the direct-view.Results32 cases were all clearly diagnosed and the worms were taken out with direct-view endoscopy or direct cholangiography with no complications.ConclusionEndoscopy is effective and accurate for the biliary tract roundworm disease and has the advantage of rapidly dispelling the sufferings of the patients.
ABSTRACT
@#ObjectiveTo study effects of oral administering alfa calcidol and diphosphonates on the bone mineral density (BMD) of patients with spinal cord injury (SCI).MethodsChanges of BMD of the 4th lumbar spine (L4), the proximal femur (total) and all of its subareas were studied between SCI cases of taking (n=31) and not taking (n=42) alfa calcidol. Changes of BMD between cases of taking diphosphonates (n=22) and not taking (n=24) were also compared.ResultsThere were no significant differences in BMD of L4, the proximal femur and all of its subareas between SCI cases of taking and not taking alfa calcidol. While there was a significant difference in BMD of the proximal femur (total) between cases of taking and not taking diphosphonates (P<0.05), and the reducing degree of BMD in the former is less than that in the latter.Conclusion Oral administering diphosphonates has a protective effect on SCI patients' BMD of the proximal femur.
