Specific tissue Doppler predictors of preserved systolic and diastolic left ventricular function after an acute anterior myocardial infarction 总被引:1,自引:0,他引:1
The degree of left ventricular (LV) dysfunction determines the outcome of patients suffering an acute anterior myocardial infarction (AAMI). Many recent studies have utilized tissue Doppler echocardiography (TDE) parameters in the assessment of LV function. We sought to investigate whether some variables easily obtained from TDE profiles of mitral annulus corners would predict a relatively preserved LV global function traditionally assessed with ejection fraction (EF) and deceleration time (DT), within the acute phase of AAMI. Included were 50 consecutive patients with a first AAMI. Standard echocardiography and TDE of mitral annulus were performed within 36 hours of admission. Pulsed wave sample volumes were set at the septal, lateral, anterior, and inferior corners of the mitral annulus. Preserved LV function was defined as an EF > 40% together with a DT > or = 140 ms and < 220 ms. An inferior annular systolic velocity of > 7.5 cm/s predicts preserved global left ventricular function with a sensitivity of 81% and specificity of 71%. An anterior mitral annular early diastolic velocity of > 8cm/s had a sensitivity of 69% and specificity of 85%. When these two velocities both exceed the limits above, such a combined index yielded a sensitivity of 69%, specificity of 94%, and an overall diagnostic accuracy of 86% for the estimation of preserved LV global function. The parameters derived from TDE profiles of inferior and anterior mitral annulus comers provide valuable information to predict preserved global left ventricular function during the early period of AAMI. 相似文献

OBJECTIVE: The aim of this study is to investigate the relationship between serum ferritin levels and disease activity in patients with systemic lupus erythematosus (SLE). METHODS: Serum ferritin levels of 72 SLE patients were measured. The SLE patients were subdivided into two groups according to SLE disease activity index (SLEDAI) as < or = 10 and > or = 11. The results were compared with 31 patients with rheumatoid arthritis (RA). 36 patients among 72 with SLE were evaluated before and after treatment. RESULTS: Serum levels of ferritin in SLE patients were higher than RA patients (p < 0.001). There was a significant difference in ferritin levels before and after treatment. The levels of ferritin in SLE were positively correlated with SLEDAI scores. Patients with SLEDAI scores > or = 11 had significantly higher serum ferritin levels. CONCLUSION: Serum ferritin levels may be a useful marker of disease activity in SLE patients. 相似文献

A pilot study was designed to investigate the efficacy of two different hyaluronic acid preparations combined to physical
therapy in patients with knee osteoarthritis in terms of reduction in pain and disability and muscle strengthening. Thirty-seven
patients with symptomatic osteoarthritis of the knees were randomly assigned into three groups. First group received a lower
molecular weight hyaluronic acid plus physical therapy, second group received a higher molecular weight hyaluronic acid plus
physical therapy, and the third group received physical therapy alone. The isokinetic knee muscle strengths and index of severity
for osteoarthritis of the knee scores were evaluated at baseline, at the end of treatment (3 weeks) and at 3 months of follow
up. At both short-term (3 weeks) and long-term (3 months) evaluations, index of severity for osteoarthritis of the knee scores
were reduced in all three groups, while there was no significant muscle strengthening.

BACKGROUND: Hyperprolactinemia has been reported to be associated with abnormalities of carbohydrate metabolism. The aim of this study was to evaluate the effects of hyperprolactinemia and bromocriptine (Brc) treatment on endothelial function, insulin sensitivity and inflammatory markers in pre-menopausal women. METHODS: Sixteen hyperprolactinemic pre-menopausal women with pituitary adenomas were recruited and 20 healthy subjects were included as controls. Patients were given Brc in doses of 2.5-20 mg/dl until normal levels of prolactin were reached. Prior to treatment and 2 months after prolactin levels were normalized, the following tests were performed. Insulin sensitivity was determined by an oral glucose tolerance test based on a formula named the insulin sensitivity index (ISI composite). Endothelial function was measured as flow-mediated dilatation (FMD) on a brachial artery using high resolution ultrasound. RESULTS: Serum glucose, insulin, estrogen, highly sensitive C-reactive protein (hsCRP), fibrinogen, homocysteine and uric acid levels were measured. Calculated ISI composite and FMD were significantly lower in the hyperprolactinemic group in comparison with the controls and improved after Brc treatment. Serum homocysteine, hsCRP and uric acid levels were significantly higher in hyperprolactinemic patients than in the controls and returned to normal levels with Brc treatment. Serum prolactin concentrations were inversely correlated with FMD measurements (r=-0.68; P<0.0001), ISI composite (r=-0.48; P<0.005) and serum estrogen (r=-0.54; P<0.005), and positively correlated with serum homocysteine concentrations (r=0.55; P<0.0001) in the hyperprolactinemic group. CONCLUSIONS: The hyperprolactinemic state is associated with impaired endothelial function and decreased insulin sensitivity, which are early markers of atherosclerosis. These alterations may predispose to the development of atherosclerosis in non-treated cases. Correction of the hyperprolactinemic state is associated with improved endothelial function and insulin sensitivity. 相似文献

In recent years, the popularity of intramedullary humeral nailing is on the rise in spite of its handicaps. There are many problems in intramedullary humeral stabilization because of the anatomic structure of the bone. We performed various methods and measurements to determine shape, length and diameter and curvature of the medullary canal of the humerus in 57 human dry cadaver bones. Anterior angulation with an average of 21 cm apart from greater tubercle was found at 1/3 distal part. Mean degree of angulation was 9 degrees (max: 15, minutes: 5, S.D.: 2.84). Humerus bones with septal aperture (supratrochlear foramen) at the fossa coronoidea were observed to have very narrow medullary canal. The best point for nail insertion was found to be an area on the line from greater tubercle anteromedially to caput humeri. This study revealed that carefully evaluated structure of humeral medullary canal and various congenital constructions such as septal aperture, and correct selection of a nail with proper length and diameter are essential for successful nailing. 相似文献

Faltering growth may be associated with adenotonsillar hypertrophy, but its pathophysiological mechanism is unclear. This study included 29 pre-pubertal children with obstructive adenotonsillar hypertrophy, and aimed to investigate the probable difference in energy intake and serum insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3) levels before and 6 months after adenotonsillectomy. Weight and height standard deviation scores, energy intake per kilogram and serum IGF-1 levels were found to be significantly higher 6 months after adenotonsillectomy, indicating that adenotonsillar hypertrophy is associated with poor growth. 相似文献

Cephalhematomas rarely lead to serious complications such as infection, osteomyelitis and skull fractures. However, we present a newborn infant with hyperkalemia in the context of a serious complication believed to be caused by hemolysis of a large cephalhematoma. The patient was treated with urgent peritoneal dialysis and discharged with a successful outcome. In conclusion, neonates with massive cephalhematoma should be closely examined in terms of bilirubin counts as well as electrolyte counts. 相似文献

Various classifications have been used for congenital anomalies of the Müllerian system. We report a case of a previously unknown anomaly of the uterus, and propose its possible embryological causes. The patient presented with primary amenorrhoea and infertility, and during laparoscopy three distinct uterine horns were observed. The tubes were connected to the two most lateral horns, each juxtaposed to a normal ovary. The middle horn had a seemingly normal attachment to the right uterosacral ligament, whereas its attachment to the left uterosacral ligament appeared attenuated and less normal. Furthermore, the right horn was immediately attached to the middle horn, whereas the left horn was, like its ipsilateral uterosacral ligament, attached to the middle horn by a more attenuated, stretched fibrous bridge. Only the middle horn, with its uterosacral ligaments, had an attached, although obstructed, cervix. Ultrasonographic examination revealed no endometrium echogeneity in any of these uterine bulbs. No etiologic factors were noted in the patient's history; her mother denied known ingestion of estrogens or other drugs while carrying her daughter. The pathogenesis of this anomaly cannot be clearly defined, but may involve sequential embryological errors of duplication of the Müllerian tracts, failure of fusion of each set of the Müllerian tracts with expected failed canalization of each tract and, finally, agenesis of the medial horn of the left duplicated tracts. 相似文献

We evaluated the clinical and immunological manifestations of 14 children with IgA deficiency. Four of the patients were asymptomatic, and ten were symptomatic, with recurrent sinopulmonary infections, allergic disease, recurrent intestinal giardiasis or celiac disease. Growth retardation was the second important feature in our patients. One of the seven patients with growth retardation had partial growth hormone deficiency. The levels of serum IgG and IgM were high in five and three patients, respectively. Cellular immunity was normal. 相似文献

Patients with type 1 diabetes mellitus are expected to respond poorly to hepatitis B (HB) vaccination. In this study we tested this hypothesis for the standard vaccination schedule. Ninety-nine patients (age 10.8 +/- 3.5 years) were vaccinated against HB (10 pg/dose at 0, 1, and 6 months) using a vaccine containing no pre-S2 antigen (Engerix Bs). The sero-conversion and -protection rates after the completion of three doses, the relation of anti-HBs titers to clinical parameters, and comparison with those of healthy counterparts (51 children, aged 9.7 +/- 4.4 years) were analyzed. The vaccine used was pre-S2 antigen containing (Genhevac B) in 23 and Engerix B in 28; both types yielded a similar response. The geometric mean of the anti-HBs titer was 322.9 vs 1476.8 IU/l (non-significant), sero-convertion rate 96.9% vs 100%, and seroprotection rate 93.9% vs 99% in the diabetic and control groups, respectively. In the diabetic group, there was no correlation between anti-HBs titer and clinical characteristics except for age. We concluded that the standard vaccination schedule is less effective but still effective enough in children and adolescents with type 1 diabetes mellitus. 相似文献
