Internal maxillary artery ligation for idiopathic intractable epistaxis

Epistaxis though common, is rarely life threatening. Routinely nose pinching, anterior find posterior nasal packing and endoscopic cauterization of bleeding points is sufficient to control epistaxis in 99% of the cases. It is mandatory to rule out local and systemic causes before labeling a case as idiopathic by using a battery of investigative modalities. Here are two interesting cases of epistaxis which did not respond to conventional therapeutic modalities in which transantral internal maxillary artery ligation was attempted leading to complete cure.     

Dynamic thiol/disulphide homeostasis and ischemic modified albumin levels in isolated oligohydramnios

ObjectiveOligohydramnios is defined as amniotic fluid index in ultrasonographic measurement is less than 5 percentile according to gestational age, the amniotic fluid volume is ≤ 5 cm, or if the single deepest dial is < 2 cm. The condition of oligohydramnios that not with fetal structural/chromosomal abnormalities, intrauterine growth retardation, intrauterine infection and maternal disease is described as isolated oligohydramnios (IO). The aim of this study is to examine whether oxidative stress and reactive oxygen species (ROS) have a place in the pathophysiology of IO.Materials and methodsIn this prospective case–control study, a total of 126 participants were included. The patient group consisted of 65 patients who were diagnosed IO, and the control group consisted of 61 healthy normal pregnants. Native thiol (-SH), total thiol (-SH + -SS), dynamic disulfide (-SS), IMA values from maternal serum were measured and compared between groups.ResultsMaternal serum -SH and -SH + -SS values were significantly lower in the IO group than in the control group (409.47 ± 55.36 μmol/L vs. 437.40 ± 48.68 μmol/L, p = 0.03 and 457.40 ± 63.01 μmol/L vs. 484.59 ± 52.75 μmol/L, p = 0.01). In the IO group when -SS/-SH and -SS/-SH + -SS ratio was found to be statistically significantly higher than control group (5.84 ± 1.1 vs 5.41 ± 0.71, p = 0.01 and 5.2 ± 0.88 vs 4.8 ± 0.58, p = 0.01), -SH/-SH + -SS ratio was significantly lower (89.56 ± 1.7 vs 90.24 ± 1.16, p = 0.01). There was no significant difference in terms of -SS value (p = 0.66). IMA value was significantly higher in the IO group than control group (0.76 ± 0.10 ABSU vs 0.68 ± 0.06, p < 0.01). It is seen as a result of ROC analysis that -SH, -SH + -SS, -SS/-SH, -SS/-SH + -SS, -SH/-SH + -SS and IMA values have a diagnostic value for IO (p < 0.05).ConclusionThe thiol/disulfide balance shifted towards oxidative stress in IO compared to control group. So oxidative stress and ROS have a place in the pathophysiology of IO.     

IMA在ACS早期诊断的临床价值

目的探讨缺血修饰白蛋白（IMA）诊断急性冠脉综合征（ACS）的价值。方法测定37倒ACS患者（实验组）和80例体检者（健康对照组）血清IMA浓度。建立IMA诊断ACS的ROC曲线，计算敏感度、特异度、阳性预测值、阴性预测值。结果健康对照组与ACS组间血清IMA浓度有显著差异，差异有统计学意义。IMA诊断ACS的曲线下面积（AZ）为0．866（95％C10．791-0．941），P〈0．001。cut—off值取80．0U／mL时，灵敏度和特异度分别为81．1％％和72．2％，阳性预测位PPV和阴性预测值NPV分别为61．0％％和89．0％。结论缺血修饰白蛋白（IMA）诊断ACS具有高灵敏度和高阴性预测值的特点；可能在早期诊断心肌缺血及辅助排除ACS上具有较大的价值。     

Ischemia-modified albumin levels in children having seizure

Convulsions are one of the frequently seen problems for a neurologist in the daily routine. It is difficult to distinguish the seizure from pseudo-seizure because of lack of conclusive tests. The aim of this study is to investigate the relationship between seizure types and seizure periods by studying IMA serum levels in children having seizure. Two groups were included (patients and control) in our study. The patient group consisted of the children admitted to Pediatric Emergency Care during January 2008–January 2010 with seizure and the control group consisted of healthy children. Serum Ischemia modified albumin (IMA) level in the group having seizures was 99.7 and 83.2 U/ml in the control group. In the comparison of the patient and control groups, significant differences were found between their IMA values (p = 0.000). There was a significant difference between IMA values of the group having generalized tonic–clonic seizures and those of the control group (p = 0.001). In comparison of the IMA values of the group having febrile convulsions and those of the control group, a significant difference was determined (p = 0.011). It has been shown that if the seizure was prolonged over 5 min, IMA level increased, and there was a significant difference between the groups experiencing over 5 min of seizures and the groups experiencing less than 5 min of seizures (p = 0.001). An increase in IMA levels in febrile convulsion supports the hypoxia development in the brain during the seizure. Serum IMA levels increased with the elongation of the seizure period and may be an indicator for status epilepticus.     

血清IMA联合血浆D-二聚体对比螺旋CT对肺栓塞患者的诊断指导意义

目的 探讨联合检测缺血修饰蛋白(IMA)及D-二聚体在肺栓塞(PE)患者的诊断价值、病情判断方面的指导意义.方法 收集了近7年来该院确诊的及疑似的肺栓塞患者56例,将确诊PE患者30例、非PE患者(疑似患者)26例、健康志愿者30例进行研究,并将PE患者30例分成3亚组:高危组、中危组、低危组,记录其外周血IMA、D-二聚体数值.并将结果与CT肺动脉造影(CTPA)结果进行对照.结果 PE组患者IMA、D-二聚体数值显著升高,相比非PE组、健康受试组具有统计学差异.与CTPA结果相符.PE患者亚组分析:高危组、中危组中IMA、D-二聚体水平相比低危组明显升高,但高危、中危组间比较没有统计学差异.结论 肺栓塞患者中,缺血修饰蛋白、D-二聚体水平越高,患者的危险分层越高,病情越重.对于可疑的肺栓塞患者,检测IMA、D-二聚体可以帮助急性肺栓塞的的诊断.

Diagnostic and prognostic value of Ischemia‐modified albumin in patients with Crimean‐Congo hemorrhagic fever

The aim of this study was to determine the diagnostic and prognostic significance of ischemia modified albumin (IMA) levels in patients with Crimean‐Congo hemorrhagic fever (CCHF). This retrospective study was conducted with patients with CCHF. IMA levels in patients with CCHF were determined using the rapid colorimetric method. IMA levels of CCHF patients were significantly higher compared with the control group (P = 0.0001). At an IMA cut‐off point of 0.555 ABSU (absorbance units), sensitivity was 65.1%, specificity 82.5%, positive predictive values (PPV) 82.5%, and negative predictive values (NPV) 65.1%. IMA levels of patients with hemorrhage were significantly higher compared with patients without hemorrhage (P = 0.005). IMA has been validated as both a new and sensitive ischemia and oxidative stress biomarker. In addition to its diagnostic significance, IMA investigated in CCHF patients at time of arrival may be an important marker with its prognostic role in determining in the early stage whether the disease will follow a hemorrhagic course.

肠系膜下动脉根部结扎在直肠癌前切除术中的应用

目的 探讨肠系膜下动脉(IMA)根部结扎对直肠癌根治术的临床应用价值.方法 将2003年1月至2007年12月收治的173例直肠癌前切除术患者随机分成两组,其中根部结扎组85例,采用IMA根部结扎术及根部淋巴结廓清,非根部结扎组88例,采用IMA低位结扎及结扎部位淋巴结廓清.根部结扎组,比较两组患者的平均手术时间、淋巴结数及转移度、复发率、5年生存率、并发症发生率.结果 非根部结扎组的淋巴结数、淋巴结转移度、术后生存率明显低于根部结扎组,复发率则明显高于根部结扎组(P＜0.05);两组手术时间、并发症比较,差异无统计学意义(P＞0.05).结论 IMA根部结扎及根部淋巴结廓清对直肠癌的治疗效果优于IMA非根部结扎及结扎部位淋巴结廓清,值得推广应用.     

Investigation of serum vitamin D and ischaemia-modified albumin levels in infertile Turkish men

Our aim was to explore the existence of a possible relationship of sperm motility with serum 25-hydroxyvitamin D3 (25-OH VD) levels and with ischaemia-modified albumin ( IMA) levels in infertile Turkish men. A total of 30 men with nonobstructive azoospermia (no spermatozoa in ejaculate), 30 men with oligospermia (total progressive motile sperm count (TPMSC) <15 × 10⁶/ml) and 33 fertile men with normospermia (with at least one child, as the control group) were enrolled in the study. The mean 25-OH VD levels for groups 1, 2 and 3 were 9.31 ± 6.46, 19.71 ± 12.80 and 30.52 ± 12.49 respectively (p < .05). There was a statistically significant difference in serum IMA levels among the groups (479.32 ± 307.56 vs. 296.37 ± 127.27 vs. 150.04 ± 81.05, respectively; p < .05). A positive correlation between serum 25-OH VD levels and TPMSC, and a negative correlation between TPMSC and serum IMA levels were determined. Infertile men had lower serum 25-OH VD and higher IMA levels than fertile men, with a positive correlation between serum 25-OH VD levels and TPMSC, and a negative correlation between TPMSC and serum IMA levels. Vitamin D supplementation may increase the sperm motility.     

IMA-7AMI冠状动脉病变程度的临床关系

目的 探讨缺血修饰白蛋白(IMA)对急性心肌梗死(AMI)冠状动脉病变程度及临床状态的诊断价值.方法 胸痛发作3h内到达医院的AMI惠者,采血测定IMA,描记12导联心电图(12-ECG),入选惠者均规范诊断、危险分层、标准治疗,行经皮冠状动脉造影,应用Gensini计分法计算其积分以反映冠状动脉病变程度,所有入选惠者根据临床killip分级及Gensini积分分组,比较IMA组间差异.结果 不同Gensini积分组问IMA值比较差异无统计学意义;killip1级组与killip>1级组问IMA值比较差异有统计学意义;经受试者工作曲线(R0(2)分析获得最适界值(cutoff)点(IMA=83.22),IMA预测急性心肌梗死发生急性心力表竭的敏感度78.9%,特异度72.4%.结论 IaMA可早期诊断急性心肌梗死,并预测心梗后急性心力表竭的发生,但IMA水平不能反映冠状动脉病变严重程度.
