Cavernous sinus thrombosis following odontogenic and cervicofacial infection

Summary Cavernous sinus thrombosis (CST) is rarely seen clinically as a complication of infectious processes since the discovery of penicillin. At the present time, dental abscess is an uncommon cause of CST. We now report our experiences with a 60-year-old diabetic male, who developed CST 38 days after extraction of an infected upper third molar tooth. The importance of eradicating regional cervicofacial foci of infection is stressed.

目的了解流行性出血热病毒(EHFV)对心脏的损害情况。方法对103例流行性出血热(EHF)患者的心电图及心肌酶学检测结果进行分析。结果72例(69.9%)患者出现心电图异常,以窦性心动过缓(27.9%)及窦性心动过速(22.3%)最常见,明显高于其它类型的心电图改变(P分别<0.05和0.001)。103例流行性出血热(EHF)患者的CK、LDH及HBDH的升高者分别为43例(41.2%)、73例(70.9%)及46例(44.7%),以LDH异常最常见。轻型、中型、重型及危重型流行性出血热患者的LDH值分别为(346.3±155.6)IU/L、(330.7±130.7)IU/L、(1114.4±872.4)IU/L及(1227.1±936.7)IU/L,经统计学处理重型及危重型的值与轻型、中型比较均有显著性或高度显者性差异。结论EHF患者并发心肌损害较普遍,而且病情愈重者,心肌损害愈严重。     

肝腺瘤的影像学诊断

目的探讨影像学(US、CT、MRI及DSA)诊断肝腺瘤的价值。方法回顾性分析经手术、病理证实的11例肝腺瘤的影像学表现,其中11例行US和CT检查(有1例行CT灌注成像,CTP),5例行MRI扫描,4例行DSA检查,并与手术病理所见对照。结果11例肝腺瘤均为单发肿块,无肝硬化背景,直径2.0～10.0cm。影像学表现:US检查,10例呈稍低或不均匀稍强回声,边界清晰,6例见低回声晕,彩色多普勒显示肿块内有较丰富的血流;CT检查,10例为稍低或等密度,8/10例动脉期全瘤明显强化,门脉期轻度强化,延迟期呈等密度,1例平扫和延迟期呈等密度,动脉期中度强化,门脉期轻度强化,误诊为血管瘤。1/11例CT灌注成像(CTP)检查,肝动脉灌注量(HAP)=1.08ml/(min.ml),门静脉灌注量(PVP)=0.19ml/(min.ml),肝动脉灌注指数(HPI)=0.85,各参数值与肝癌均有明显不同;MRI检查,5例肝腺瘤均能显示完整包膜,T1WI上2例稍高于肝脏信号,1例呈等信号,2例为稍低信号,T2WI上5例均表现为以稍高信号为主的混杂信号,脂肪抑制像(STIR)1例呈略低信号,4例信号与T2WI相似,行增强扫描的4例病灶动脉期显著强化,门脉期强化减退,平衡期呈等信号。DSA检查,3/4例病灶见粗细不均的异常血管影,实质期可见肿瘤染色表现。结论肝腺瘤的US和DSA表现均缺乏特异性,CT、MRI则具有一定的特点。CTP对肝腺瘤可能具有诊断和鉴别诊断价值。

重度烧伤患者休克期血浆B型钠尿肽含量变化及意义

Objective To study the plasma content of B-type natriuretic peptide (BNP) in patients with severe burn during shock stage and probe its clinical significance. Methods Forty-two patients aged 18-60 years, with total burn surface area ≥30%TBSA or full-thickness burn area ≥10% TBSA, hospital-ized within 4 hours after burn, were divided into A group (with total burn surface area 30% -50% TBSA or full-thickness burn area 10% -20% TBSA, n = 21 ), and B group (with total burn surface area 50% TB-SA or full-thickness burn area > 20% TBSA, n = 21 ). Twenty patients admitted during the same time for plastic surgery were enrolled as control group. The plasma levels of BNP, creatine kinase (CK), CK-MB, troponin I (Tnl) of all patients were determined on admission. The levels of BNP, Tnl and fluid resuscita-tion volume were examined at 8, 16, 24, 48 post burn hour (PBH) in A and B groups. Analysis of correla-tion between BNP and fluid resuscitation volume was performed. Results On admission: BNP level in A group (68±19 ng/L) and B group (99±38 ng/L) , respectively, was increased as compared with that in control group (17±7 ng/L, P <0.01 ). Tnl level in A group (2.13±0.67 μg/L) and B group (2.98± 0.58μg/L), respectively, was increased as compared with that in control group (0.12 ± 0.03 μg/L, P < 0.01). There was no obvious difference in CK, CK-MB levels among A, B, and control groups ( P > 0.05). BNP levels in A, B groups continuously rose during 8 - 48 PBH, and they were positively correlated with fluid resuscitation volume. TnI level peaked at 24 PBH, and decreased at 48 PBH. Conclusions The plasma level of BNP is sensitive to reflect changes in myocardial ischemia and hypoxia as a rise in level of TnI in shock stage of severe burn, and it was positively correlated with fluid resuscitation volume. BNP can be used to guide fluid resuscitation during shock stage.
