Valor de la escala ASPECTS de circulación posterior y del índice puente-mesencéfalo en imágenes de TC sin contraste y angiografía por TC en pacientes con oclusiones de la arteria basilar recanalizados tras trombectomía mecánica

Purpose

Endovascular treatment with mechanical thrombectomy devices demonstrated high recanalization rates but functional outcome did not correlate with high rates of recanalization obtained. Patient selection prior to the endovascular treatment is very important in the final outcome of the patient. The primary aim of our study was to evaluate the prognostic value of posterior circulation Alberta Stroke Program Early CT Score (pc-ASPECTS) and Pons-Midbrain Index (PMI) scores in patients with Basilar Artery Occlusion (BAO) treated with successful angiographic recanalization after mechanical thrombectomy.

甲睾酮对小鼠生殖系统发育及生精功能的影响

目的 探讨甲睾酮对雄性小鼠精子的产生及生殖器官的影响.方法 将48只昆明小白鼠随机分为4组,每组12只,每天分别向各组灌胃甲睾酮16 mg/kg,32 mg/kg,64 mg/kg 和等量蒸馏水(对照组),连续10 d.结果 与对照组比较,甲睾酮16 mg/kg组精子活率最高为66.22%(P<0.05);甲睾酮64mg/kg组睾丸指数、精子畸形率、精子密度都极显著和显著地升高(P<0.01和P<0.05),且睾丸组织有较明显的病理学损伤.结论 适量甲睾酮能提高精子活率,大剂量使精子活率降低且畸形率升高.     

A new strategy of delayed long-term prophylaxis could prevent cytomegalovirus disease in (D+/R−) solid organ transplant recipients

Abstract:  Long-term prophylaxis against cytomegalovirus (CMV) started immediately after transplantation in (D+/R−) poses a higher risk of late-onset CMV disease. Delayed CMV prophylaxis could allow a transitory exposure of the immune system to CMV, which would let the immune system mount an adequate CMV-specific cytotoxic response in (D+/R−) patients and confer protection against CMV disease. We included all (D+/R−) solid organ transplant recipients (SOT) performed at our institution (January 3/October 6) who received CMV prophylaxis (mainly with oral valganciclovir) during 100 d. In the first period (until December 4), prophylaxis was initiated immediately after transplantation (conventional prophylaxis: CP). Since January 5, it was initiated after 14 d (delayed prophylaxis: DP). Incidence and severity of CMV disease was compared between both groups. A total of 44 SOT recipients were included (CP: 26 and DP: 18). CMV disease was diagnosed in eight patients (18%), seven of 26 (27%) in the CP group, and one of 18 (5.5%) in the DP group (p = 0.07). CMV colitis was reported in five of 26 patients in the CP group (19%), whereas there were no cases of visceral CMV disease in the DP group (p = 0.048). A 14-d delay in the beginning of long-term prophylaxis against CMV in (D+/R−) is safe and could prevent the onset of late-CMV disease.     

复方醋酸环丙孕酮和罗格列酮序贯用药对氯米芬抵抗的多囊卵巢综合征患者内分泌及生育功能的影响

目的探讨复方醋酸环丙孕酮和罗格列酮序贯用药对改善多囊卵巢综合征（PCOS）患者生育功能的临床疗效。方法30例氯米芬抵抗的PCOS胰岛素抵抗患者，口服复方醋酸环丙孕酮3个月后，罗格列酮联合氯米芬用药6个月，比较用药前后体重指数、月经周期、生殖激素水平、排卵率、妊娠率、血糖和胰岛素水平的变化。结果与用药前相比，服用复方醋酸环丙孕酮后，雄激素水平和LH／FSH值明显降低（P〈0．05），服用罗格列酮后，胰岛素抵抗指数（Homa IR）、胰岛素分泌指数（Homa β）以及β细胞功能评定指数（MBCI）均较用药前降低（P〈0．05）。结论复方醋酸环丙孕酮和罗格列酮序贯用药可有效地抑制氯米芬抵抗的PCOS患者的高雄激素血症，改善胰岛素抵抗及生育功能。     

Sonographic diagnosis of early recurrence after inguinal herniorrhaphy: Potential pitfalls

Three patients who presented with scrotal swelling within a few days of inguinal herniorrhaphy are reported. Ultrasonography scans performed in these patients all demonstrated features suspicious of recurrence of hernia. One patient underwent surgical exploration, which revealed only a scrotal haematoma without evidence of recurrent hernia. The other two patients were managed conservatively because clinically the swellings were regarded to be more compatible with haematoma. Both patients had subsequent resolution of the scrotal swelling with no clinical evidence of recurrence of hernia on follow‐up. It is concluded that sonographic diagnosis of recurrence of hernia shortly after inguinal herniorrhaphy can occasionally be misleading.     

小脑后下动脉动脉瘤的诊断和治疗

目的探讨小脑后下动脉动脉瘤的临床特征、诊断、鉴别诊断和治疗。方法回顾性分析12例小脑后下动脉瘤的临床表现、影像学特征、手术效果及诊治过程中存在的相关问题。结果12例中有11例因动脉瘤破裂出血而发病,单纯第四脑室出血4例,全脑室系统出血2例,小脑半球出血3例,小脑蚓部伴第四脑室出血1例,侧脑室伴第三脑室出血1例,以后颅窝占位病变表现1例。8例术前行DSA检查明确诊断,4例术中明确诊断。12例均行后颅窝开颅显微手术治疗,其中动脉瘤颈夹闭9例,孤立切除2例,动脉瘤加固术1例,术后2例因脑积水加重行脑室-腹腔分流术。12例中除1例术后留有轻偏瘫外,其余11例恢复良好。结论小脑后下动脉瘤多以第四脑室出血发病,少数以小脑半球或蚓部出血发病,及早治疗效果满意。手术方式应尽量夹闭动脉瘤颈,对于小脑后下动脉末端动脉瘤,可以采用孤立切除术。     

96例神经症患者人格特质分析

目的 对精神症患者与正常人的人格特质进行比较。方法 应用《修订卡氏16种人格因素量表》，对96例神经症患者与94名正常人进行测试。结果 神经症患者人格类型内向型占68．18％，焦虑型90．19％，明显高于正常组（P＜0．001）；因此C（稳定性）、E（恃强性）、F（兴奋性）、G（有恒性）、H（敢为性）的量表分低于正常人组（P＜0．001）；心理健康因素均分低于正常人组（P＜0．001）。结论 神经症患者人格特质与正常人之间存在显著差异。
