Context: Adenoviral conjunctivitis.Objective: To examine the effects of conjunctival irrigation with povidone iodine in infants with adenoviral conjunctivitis. Material and methods: An outbreak of adenovirus conjunctivitis occurred between September and December 2012 at the neonatal intensive care unit of our hospital. Forty-three infants with adenoviral conjunctivitis were examined in this study. Thirty-five eyes of 35 infants who had detailed ophthalmological examination and clinical scoring were included. The conjunctiva of 15 infants (Group 1) were irrigated with povidone iodine 2.5% solution and then treated with preservative-free artificial tears and preservative-free antibiotic drops. Twenty infants (Group 2) were treated only with the same drops with the same posology, without conjunctival irrigation with povidone iodine. Patients were examined two times a week until the complete recovery. Lid edema, conjunctival chemosis, fragility of conjunctival vasculature, pseudomembrane formation, and corneal involvement were scored clinically. Results: Twenty patients (57%) were female and 15 patients (43%) were male and mean age was 3.1 months (ranged from 1 to 4 months). No relation was found between gender and clinical scores. Statistically significant lower clinical scores were obtained from Group 1. The median recovery time was earlier in Group 1 (7?d) than Group 2 (12?d) (p?=?0.001). Conclusion: Conjunctival irrigation with 2.5% povidone iodine is effective in the treatment of adenoviral conjunctivitis in infants. 相似文献

We report on a patient in whom a giant thrombus in the left atrium was detected by transthoracic echocardiography. Anticoagulant theraphy was started. After two months of therapy, repeat echocardiography showed complete resolution of the thrombus. This case indicates that large and presumably organised thrombi may be treated with anticoagulant therapy. 相似文献

In 1974, Wu and Hoak described a method for determining circulating platelet aggregates. This method was modified by Grotemeyer in 1983. The platelet reactivity index (PR) is based on the ratio of platelet aggregates in blood samples obtained in different buffer solutions. Platelet aggregates are resolved when blood is sampled in EDTA-buffer, but remain fixed when EDTA-formalin-buffer is used. Generally, the PR is preferred, because in vitro manipulations of platelets are not necessary, and the results are calculated. PR values above 1.05 are suspicious for elevated platelet aggregation. PR values above 1.2 indicate pathological changes in platelet aggregation. The PR is inexpensive (4.0 euro dollars) and rapid to perform. PR values were used successfully to identify nonresponders to secondary prophylaxis with acetylsalicylic acid (ASA), that is, patients suffering from stroke (33%) and patients after cardiac ischemia (18%). Furthermore, elevated PR values correlated significantly with the incidence of arterial thromboembolic complications. The PR correlated well in our prospective study with values received from the retention test Homburg (RT-H) and the platelet function analyzer (PFA-100). The data indicate that the values of the PR seem to be highly predictive for the evaluation of the ASA therapy. However, the PR is not feasible for the determination of the ASA overdosage. 相似文献

Aim
To evaluate the association between respiratory tract Ureaplasma urealyticum (Uu) colonization and development of retinopathy of prematurity (ROP) requiring treatment.Methods
The infants with birthweight (BW) ≤1250 g born in a third-level neonatal intensive care unit between March 2009 and May 2010 were prospectively identified. Nasopharyngeal swabs for Uu colonization were taken in postnatal first 3 days. Culture-positive patients were reevaluated on the twelfth day by nasopharyngeal swabs for Uu. The primary outcome was to define whether there was an association between respiratory tract Uu colonization and severe ROP requiring treatment. Independent sample''s t-test or Mann–Whitney U-test was used to compare continuous variables and Chi-square test or Fisher''s exact test for categorical variables. Multivariate (backward) logistic regression analysis was performed to simultaneously measure the influence of the independent variables with ROP as the dependent variable.Results
A total of 25 (12.1%) infants developed severe ROP requiring treatment among 206 infants who underwent ROP screening. Mean BW and gestational age of total cohort were 1013±159 g and 27.9±1.6 weeks, respectively. Multivariate analysis demonstrated that BW (OR: 0.64 (95% Cl 0.47–0.88); P=0.006), duration of mechanical ventilation (OR: 1.17 (95% Cl 1.06–1.28); P=0.001), premature rupture of membrane >18 h (OR: 3.83 (95% Cl 1.2–12.2); P=0.02), and Uu positivity in both cultures (OR: 5.02 (95% Cl 1.8–13.9); P=0.002) were independent risk factors for the development of severe ROP requiring treatment.Conclusions
Respiratory tract colonization with Uu was independently associated with severe ROP requiring treatment. 相似文献5.
Effects of diode laser photocoagulation treatment on ocular biometric parameters in premature infants with retinopathy of prematurity 下载免费PDF全文
AIM:To investigate the effects of diode laser treatment on ocular biometric parameters in premature infants with retinopathy of prematurity(ROP).METHODS:Premature infants who received diode laser treatment for ROP(n=68)and premature infants with spontaneous regressed ROP without treatment(n=50)were performed longitudinal ocular biometric measurements including anterior chamber depth,lens thickness and axial length as follows:1 d prior to laser treatment,and 3,6,9,and 12 mo after the laser treatment.RESULTS:The mean birth weight,gestational age and initial examination time values were 936.53±302.07 g,26.66±2.42 wk,36.26±2.73 wk in the treatment group and 959.78±260.08 g,27.28±2.10 wk,36.56±2.54 wk in the control group.There was no statistically significant difference in these demographic characteristics of the groups.Anterior chamber depth,lens thickness and axial length demonstrated statistically significant linear increases during the study period in the two groups(P<0.001 for each).There were no statistically significant differences between the two groups in terms of anterior chamber depth after laser treatment.Measurements of the lens thickness at 9 th and 12 th months(9 th month 3.70±0.22 vs 3.60±0.21 mm,P=0.017;12 th month 3.81±0.21 vs 3.69±0.22 mm,P=0.002)and the axial length at 12 th month(19.35±0.79 vs 19.13±0.54 mm,P=0.031)after laser treatment were statistically higher in the treatment group.CONCLUSION:Diode laser retinal photocoagulation treatment in premature infants seems to increase the lens thickness and axial length. 相似文献

Effect of N-acetylcysteine on oxidative stress and ventricular function in patients with myocardial infarction 总被引:2,自引:0,他引:2
Recent evidence suggests that postischemic myocardial dysfunction (“stunning”) may be mediated by oxygen free radicals. Various
studies have reported the beneficial effects of antioxidants in ischemia–reperfusion injury. The aim of this study was to
assess the effect of N-acetylcysteine (NAC) treatment on oxidative stress, infarct size, and left ventricular (LV) function, as adjunct therapy
in myocardial infarction (MI). Patients with acute MI received either 15 g NAC infused over 24 h (n = 15) or no NAC (n = 15), combined with streptokinase. Peripheral venous blood was serially sampled to measure creatine kinase (CK)-MB levels.
Plasma malondialdehyde (MDA) level was measured at admission and after 4 and 24 h. Echocardiography was performed within 3
days of MI and after 3 months. At admission, plasma MDA levels were not different between the groups. In the NAC-treated patients
plasma MDA levels decreased, whereas in the nontreated NAC patients MDA levels increased at 4 and 24 h (P < 0.01 and P < 0.001, respectively). Left ventricular ejection fraction was higher (P < 0.05) and LV end-systolic and end-diastolic diameters were lower (P < 0.001 and P < 0.001) in patients receiving NAC on day 3. Left ventricular wall motion score index was significantly lower in patients
treated with NAC on day 3 (P < 0.05). Left ventricular diastolic parameters were not different whether patients were treated with NAC or not. No difference
in reduction of infarct size was detected between the groups according to CK-MB levels. It was thus demonstrated that administration
of NAC in combination with streptokinase significantly diminished oxidative stress and improved LV function in patients with
acute MI. These encouraging results would justify the performance of a larger controlled study. 相似文献

Purpose
Some patients with shoulder laxity complain of coxalgia without a history of trauma. We hypothesised that patients who have recurrent shoulder instability accompanied with generalised joint hyperlaxity tend to have acetabular dysplasia.Methods
Pelvic radiographs of 26 young patients with hyperlaxity who had shoulder instability complaints without any history of hip joint trauma were evaluated by measuring their centre-edge angle (CEA) and acetabular angle (AA). In addition, Beighton generalised joint laxity tests were performed. All of the patients had shoulder pain and instability accompanied with hyperlaxity. We performed magnetic resonance imaging examination to show SLAP-Bankart lesions and pelvis anteroposterior X-rays to detect acetabular dysplasia.Results
The average age of the study group was 26?±?8.03 years (13-39). Six patients were female and 20 were male. When CEA (<22.6 degrees) was used as a criterion for acetabular dysplasia, the dysplasia rate of our patient group was 3.84 % for the right hip, 3.84 % for the left hip and 3.84 % overall. When AA (>42.2 degrees) was used as the dysplasia criterion, the dysplasia rate of patient group was 30.76 % for the right hip, 57.69 % for the left hip and 57.69 % overall.Conclusions
CEA values were significantly lower (p?=?0.009) and AA values were significantly higher (p?<?0.001) in our study group than the previously-reported average values of the Turkish population. We think that acetabular dysplasia is more frequent in patients with hyperlaxity; further studies are needed to test this idea.9.

Intramedullary nailing is the gold standard for the treatment of diaphyseal femoral fractures. Bending of the nail secondary to trauma is a rare complication encountered in unhealed and comminuted fractures. A 23-year-old man was admitted with refracture of the right femoral shaft and a 32-degree bending of an inflatable intramedullary nail due to a fall, two months after the initial surgical treatment. The nail was first straightened by exerting an external force, which decreased the angulation to 10 degrees. Then, the fracture site was opened, the lateral wall of the nail was drilled, and one of the four metal bars of the nail was cut. This allowed complete straightening of the nail by the same maneuver and its removal. A new inflatable intramedullary nail was placed and union was achieved after four months. Tools that may be necessary to cut the nail partially or totally should be made available for removal of bent nails. 相似文献
