Spontaneous mesenteric hemorrhage associated with ehlers-danlos syndrome

The vascular type of Ehlers-Danlos syndrome is a genetic disorder of connective tissue and is frequently associated with catastrophic arterial complications. Its surgical treatment is extremely difficult because of the fragility of vessels. This article describes three patients with vascular type of Ehlers-Danlos syndrome who developed mesenteric hemorrhage due to spontaneous arterial rupture. The clinical and molecular characteristics of the disease are briefly reviewed.     

Ventriculosubcutaneous shunt for temporary treatment of neonatal post-IVH hydrocephalus: a technical note

A technique for temporary ventricular drainage using a subcutaneous pouch is described for use in neonatal hydrocephalus after intraventricular hemorrhage. The advantages include continuous, valve-regulated ventricular decompression, no exposed tubing, avoidance of electrolyte imbalance and of the loss of CSF, obviation of the need for repeated tapping, and the ability to convert to a peritoneal shunt on an elective basis.

Clinical impact of CCM mutation detection in familial cavernous angioma

Introduction and background A 3-year-old Bosnian girl with a large symptomatic brainstem and multiple supratentorial cavernous angiomas, who underwent neurosurgical treatment, is presented. As multiple cavernomas are more common in familial cases, genetic analyses and neuroradiological imaging were performed in the patient and her parents to see whether there was any evidence for inheritance. This information is important for genetic counseling and provision of medical care for at-risk relatives. Currently, no recommendation is available on how to manage these cases.Results Genetic analyses demonstrated a novel CCM1 frameshift mutation (c.1683_1684insA; p.V562SfsX6) in the child and the asymptomatic 27-year-old mother. Sensitive gradient-echo magnetic resonance imaging of the mother revealed multiple supratentorial lesions, whereas analogous imaging of the father showed no pathological findings.Conclusion This case exemplifies that seemingly sporadic cases with multiple lesions might well be hereditary and that presymptomatic genetic testing of family members may identify relatives for whom clinical and neuroradiological monitoring is indicated.     

急性脑出血患者血清谷氨酸动态变化分析

目的通过观察脑出血（intracerebral hemorrhage，ICH）患者血清中谷氨酸的动态变化来进一步评价谷氨酸对脑出血的作用。方法选择符合条件的30例急性高血压脑实质出血患者，给予神经内科脑出血常规治疗，采用高效液相色谱法检测起病后2d内、5．6d、8-9d和15．16d的血清谷氨酸浓度，同步进行神经功能评定，同时于发病后1．3d、d5-6d及d15．16行头部CT检查了解血肿体积大小。结果脑出血患者血中谷氨酸浓度与血肿体积及神经功能缺损评分之间呈正的直线相关。经治疗后，所有病例谷氨酸水平迅速下降，在5-6d和8—9d下降速度更加明显。结论谷氨酸可能参与了自发性脑出血患者的急性期脑损伤作用。     

MRI relaxation fluctuations in acute reperfused hemorrhagic infarction.

MRI evaluations of intramyocardial hemorrhage in acute infarction have relied on T(2) and T(2)(*) shortening only. We propose a more comprehensive evaluation of hemorrhagic infarction based on the concept that fluctuations in T(2) and T(1) relaxation in acute reperfused infarction will reflect transient edema and hemoglobin oxidative denaturation to uncompartmentalized methemoglobin. Anteroapical infarction was created via percutaneous balloon in young swine (22-25 kg, N = 12). T(2), T(1), diastolic wall thickness (DWT), and the Gd-DTPA partition coefficient (lambda) were measured on days 0, 2, and 7. DWT was elevated at 1 hr postreperfusion (128% +/- 53%, P = 0.0001), and alleviated on days 2 and 7 (48% +/- 10%, P = 0.008; 53% +/- 24%, P = 0.003). T(2) and T(1) elevations were coincident with early edema (DeltaT(2) = 55% +/- 24%, P < 0.0001; DeltaT(1) = 27% +/- 18%, P < 0.04). T(2) and T(1) were nearly normal on day 2 (DeltaT(2) = 8% +/- 8%, P = 0.27; DeltaT(1) = 0% +/- 1%, P = 0.65). On day 7, T(2) increased while T(1) decreased (DeltaT(2) = 27% +/- 16%, P = 0.005; DeltaT(1) = -14% +/- 10%, P = 0.02). Lambda was elevated by >150% at all time points (P < or = 0.002). Histology verified hemorrhagic injury. T(1) and T(2) fluctuations are consistent with transient edema, as well as hemoglobin oxidative denaturation to decompartmentalized methemoglobin. This methodological development may broaden our understanding of hemorrhagic microvascular injury and improve its detection in clinical populations.     

Misoprostol in preventing postpartum hemorrhage: a meta-analysis.

OBJECTIVE: To assess misoprostol's ability to prevent postpartum hemorrhage (PPH) where no alternatives exist. Comparison to oxytocics demonstrates how similarly misoprostol achieves a level of effectiveness-obtainable only in hospitals-in remote locations around the world. METHOD: Using the Mantel-Haenszel fixed-effects model and the DerSirmonian and Laird random-effects model, summary statistics indicated that misoprostol's excess risk of PPH was only 4% when compared to oxytocics. RESULT: This risk difference was well within the range of expected results for all uterotonic agents and does not warrant branding misoprostol as an inferior drug. CONCLUSION: Conventional uterotonic drugs should not be used to set the lowest-accepted level of effectiveness in settings where they are entirely unsuitable. Continuing to weigh the benefits of one effective drug against another only delays the distribution of misoprostol in countries where it is the only feasible choice and must be measured against no treatment at all.
