We describe eight children with complex I deficiency, four of them with an isolated, the other four with an additional deficiency of complex IV. Clinical, chemical and morphological findings were compared from patients with isolated and combined deficiency. In both groups, the age of onset of symptoms was between the 1st day and the 4th month of life. Clinical and biochemical heterogeneity were observed. We found no correlation between residual activity of complex I in muscle, blood lactate level, and severity of clinical symptoms. Newborns presenting with severe lactic acidosis and children with later onset myopathy were seen in both groups. The group with combined complex I deficiency showed a more severe clinical course. By light microscopy ragged red fibres were only found in two patients with combined deficiency. However, by electron microscopy structural alterations of the mitochondria were observed in six out of seven muscle specimens. 相似文献

In patients with severe genetic hypercholesterolemia, therapeutic reduction of elevated serum total cholesterol and LDL cholesterol should begin in early childhood to lower the risks of cardiovascular disease later in life. We evaluated the effects of outpatient therapy with diet alone and with combined diet and drug therapy in children and adolescents with hypercholesterolemia of apparent dominant inheritance. Serum lipid values before and during dietary treatment were available in 35 patients (mean age at start of treatment 7.9 years, range 2.0-17.6 years) followed for an average duration of 17.5 months (range 4-70 months). A comparison between untreated state and combined therapy with diet and cholestyramine was possible in 14 patients (mean age 8.6 years, range 2.4-17.0 years) followed for 27.9 months (range 4-97 months). Dietary modification achieved by repeated counseling and training lowered serum total cholesterol by mean (+/- SE) 11.7 +/- 1.9% (p < 0.0001) and LDL cholesterol by 17.3 +/- 3.5% (p < 0.0001). However, five of 35 patients did not show an appreciable effect of therapy (cholesterol reduction < 5%), possibly because of non-compliance. Diet combined with cholestyramine in an average dose of 0.36 g/kg body weight/day reduced total cholesterol by 33.0 +/- 2.4% (p < 0.0001) and LDL cholesterol by 37.5 +/- 4.3% (p < 0.0001) and was effective in all patients. Both forms of treatment had no effect on serum triglycerides and HLD cholesterol. No serious side effects were noted, and percentile values for weight and height remained unchanged in all but three obese children.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: To examine patient characteristics, patterns of injury, forensic evidence, and the frequency of sexual assault in postmenopausal rape victims from 1986-1991. METHODS: Medical and forensic records were reviewed from 129 postmenopausal women (50 years of age or older) and 129 women from a comparison group (14-49 years of age) who reported having been sexually assaulted. Statistical analysis was performed by Student t test, chi 2, multiple logistic regression, or Fisher exact test. RESULTS: Postmenopausal women represented 2.2% of women reporting sexual assault in Dallas County. The postmenopausal victim was more often white (64%), whereas the younger victim was more often black (53%). Drug or alcohol use within the previous 24 hours was more common in the younger group. Trauma, in general, was common, occurring in 67% of the postmenopausal women and 71% of the younger group (P = not significant). Genital trauma was more common in the postmenopausal group (43 versus 18%; P < .001). Nearly one in three postmenopausal women had genital abrasions or edema. Almost one in five older women had genital lacerations, with one in four severe enough to require surgical repair. In contrast, the frequency of extragenital trauma was more common in younger victims (66 versus 49%; P < .01). Forensic findings were similar in both groups; however, in postmenopausal women motile spermatozoa were seen only in those examined within 6 hours of the assault. CONCLUSION: Postmenopausal women who have been sexually assaulted are more likely to sustain genital trauma than younger victims. 相似文献

Screening for coeliac disease (CD) with serum antigliadin antibodies (AGA) was performed in 1032 diabetic children and adolescents. In 8 children CD had been diagnosed before study entry. Of the remaining 1024 children, 33 had an elevated AGA titre in the first serum sample. On follow-up an elevated AGA titre was confirmed in only 17 of 31 patients. Nine of the repeatedly positive patients underwent jejunal biopsy, and CD was diagnosed in two asymptomatic patients; both were positive for IgG- and IgA-AGA. Among 10 AGA-positive patients in whom biopsies could not be performed, only 1 showed IgA-AGA and thus carried a high risk for CD. From our results we estimate a prevalence of CD in Swiss and German diabetic children between 1.1% and 1.3%. Falsepositive AGA titres occurred significantly more often in patients with diabetes duration of less than 1 year. AGA testing teached a specificity of 99% if performed at least 1 year after the onset of diabetes. Children suffering from both diabetes and CD showed a diabetes manifestation at a significantly younger age than non-coeliac patients, whereas CD tended to be diagnosed at a remarkably late age.Abbreviations AGA

The effectiveness of sunscreens was originally achieved by incorporation of soluble organic UV absorbers such as cinnamates and others into cosmetic formulations. Determinations of the sun protection factor (SPF) of emulsions containing different organic UV absorbers clearly indicate that the efficacy depends on the absorption characteristics of each single UV filter substance. Nowadays, micronised pigments such as titanium dioxide or zinc oxide have also been found to be protective against harmful UV rays. Our investigations using optical and electron microscopy proved that neither surface characteristics, particle size nor shape of the micronised pigments result in any dermal absorption of this substance. Micronised titanium dioxide is solely deposited on the outermost surface of the stratum corneum and cannot be detected in deeper stratum corneum layers, the human epidermis and dermis. 相似文献

Trichomonas vaginalis is the most common nonviral sexually transmitted disease in the world. Recent research has elucidated several virulence factors
that allow T. vaginalis to adhere to extracellular host proteins and evade the host immune system. Further investigation is needed to determine the
mechanisms responsible for the perinatal morbidity associated with trichomoniasis and to evaluate the interactions between
trichomoniasis and HIV infection. An effort to decrease T. vaginalis associated with perinatal morbidity by metronidazole treatment in pregnancy was unsuccessful. However, more sensitive tools
for diagnosis such as polymerase chain reaction may further facilitate future understanding of the epidemiology and risk factors
of disease and improve approaches to control this widespread infection. Treatment has remained highly efficacious with single-dose
metronidazole, although concern regarding drug resistance has led to more systematic evaluations of the prevalence of metronidazole
resistance and alternatives to metronidazole treatment. 相似文献

PURPOSE: The aim of this study was to evaluate the thrombogenicity of different peripheral stent types in a standardized in vitro model with fresh human whole blood. MATERIALS AND METHODS: Different stents (N = 77; n = 7 of each of 11 types) were implanted in polyvinyl chloride tubing loops and filled with donor blood samples. After 120 minutes of blood circulation, the thrombin-antithrombin III complex (TAT) levels, beta-thromboglobulin (beta-TG) levels, and platelet counts were assessed. RESULTS: After 2 hours, significant differences were seen. TAT values (+/- SD) with the investigated stents were 31 micro g/mL +/- 20 (control, no stent), 328 micro g/mL +/- 206 (Saxx stent, peripheral medium CrNi31 L), 651 micro g/mL +/- 760 (Palmaz Corinthian Stent, 316 L stainless steel, electropolished), 1,609 micro g/mL +/- 1,264 (Palmaz Corinthian Stent, 316 L stainless steel, not electropolished), 810 micro g/mL +/- 578 (Palmaz Schatz long medium stent), 569 micro g/mL +/- 347 (Smart Nitinol stent), 1,037 micro g/mL +/- 577 (Megalink peripheral stent), 543 micro g/mL +/- 487 (peripheral stent, electropolished), 1,674 micro g/mL +/- 2,057 (peripheral stent, not electropolished), 3,128 micro g/mL +/- 1,812 (SelfX Nitinol stent, polished), 5,897 micro g/mL +/- 2,380 (SelfX Nitinol stent, unpolished), and 1,458 micro g/mL +/- 887 (bridge stent). The platelet count (x1,000/ micro L +/- SD) was 218 +/- 35 (control, no stent), 188 +/- 22 (Saxx stent), 187 +/- 20 (Palmaz Corinthian stent, electropolished), 135 +/- 37 (Palmaz Corinthian stent, not electropolished), 170 +/- 24 (Palmaz Schatz stent), 180 +/- 36 (Smart Nitinol stent), 159 +/- 26 (Megalink peripheral stent), 173 +/- 17 (peripheral stent, electropolished), 133 +/- 51 (peripheral stent, not electropolished), 123 +/- 37 (SelfX Nitinol stent, polished), 52 +/- 27 (SelfX Nitinol stent, unpolished), and 130 +/- 31 (bridge stent). CONCLUSION: This standardized study showed a wide range of platelet activation after stent implantation. Electropolishing clearly reduced the thrombogenicity of the stents. 相似文献

Our objective was to evaluate the long-term effects of dietary therapy of tyep I glycogen storage disease which avoids increased
lactate production during childhood and adolescence. In order to suppress hepatic glucose and increased lactate production
consistently day and night, the treatment regimen included nocturnal intragastric feeding of glucose polymer during childhood
and adolescence. The aim was to keep the blood glucose concentration in the “high normal range” (4.3–5.5 mmol/l) and the lactate
concentration in urine in the normal range (<0.06 mol/mol creatinine). The amounts of dietary carbohydrate required decreased
in an age-related manner from 11.9±1.3 mg/kg body weight per min by day and 6.9±0.9 mg/kg body weight per min by night at
1 year of age to 5.2±1.0 and 2.9±1.2 mg/kg body weight per min, respectively, at the age of 16 years. In 15 infants, therapy
started at 5.8±3.2 months of age and induced catch up growth over 1–2 years by which time the mean height SDS increased from
−1.02±0.91 to −0.19±1.07. In the well controlled patients, further growth continued within that range. From 12 years of age,
mean height SDS was in line with the respective mean SDS of mid-parental target height. The plasma lipid concentrations were
markedly reduced, but were not brought into the normal range. So far, no adolescent showed liver adenoma or renal damage.
Four patients with poor metabolic control due to poor compliance with treatment (frequently subnormal plasma glucose concentrations,
severe hypoglycaemia, and increased urinary lactate excretion) showed retardation of growth and bone maturation.Conclusion: avoiding increased lactate production by keeping the blood glucose concentration permanently in the “high normal range”
seems to be crucial for growth according to the genetic potential.
