ObjectiveTo summarize the clinical features of an adult patient with occult cerebral alveolar echinococcosis with liver and lung infection. MethodsA Tibetan male patient in his middle age from the epidemic area of echinococcosis infection was diagnosed to have liver, lung and cerebral alveolar echinococcosis infection in Ganzi People's Hospital. He had the resection surgery, and the pathological result confirmed the primary diagnosis. We searched the literatures from January 1985 to December 2015 for occult cerebral alveolar echinococcosis and reviewed all the full texts in China Journal Full-text Database. Seventeen articles were qualified and 42 patients were reported. Combining with the relevant English literature using Medline, we analyzed the epidemic, pathophysiological and clinical manifestations of cerebral alveolar echinococcosis infection and explored the methods of prevention and treatment. ResultsAccording to the results of literature analysis, cerebral alveolar echinococcosis appeared often secondary to infection of other organs. Nervous system symptom concealed or progressed slowly; imaging and pathological tests were important for diagnosis. Resection surgery was the essential method of cure. ConclusionAlveolar echinococcosis can affect multiple organs. In patients without neurological symptoms, if other organs are found to be infected, it is important to screen patients with intracranial involvement. Because this kind of patients with intracranial lesions with hydatid are often secondary to other organ infection, active treatment in early phase is necessary in order to avoid further expansion of lesions and metastasis.
Intracranial Acinetobacter baumannii infection is a rare clinical disease with a gradual increase in incidence and extremely high mortality. With the continuous enhancement of bacterial resistance, more and more intracranial infections of multidrug-resistant and extensively drug-resistant Acinetobacter baumannii have appeared in the clinic, and its treatment has become a major challenge and problem faced by neurosurgeons. The treatment difficulties include the selection, usage and dosage of antimicrobial agents, as well as whether cerebrospinal fluid drainage is needed. A standardized treatment plan is still needed. In this paper, combining domestic and foreign literature, the treatment of intracranial infection of multidrug-resistant and extensively drug-resistant Acinetobacter baumannii will be reviewed in order to provide a reference for clinical treatment.
Objective To retrieve, evaluate, and summarize evidence on the prevention and management of intracranial infections related to lumbar drainage (LD), in order to provide scientific references for clinical practice and decision-making. Methods The literature on the prevention and management of LD-related intracranial infections in LD-related websites and databases was systematically searched, with a search period from the establishment of databases to June 30, 2024. The included literature was evaluated for quality and integrated into evidence. Results A total of 9 articles were included, including 3 guidelines, 1 evidence summary, 1 expert consensus, 1 systematic review, and 3 original studies. A total of 30 pieces of evidence were formed, covering six aspects: risk management, catheter placement, catheter maintenance, extubation, diagnosis and treatment of intracranial infections, education and training. ConclusionsThe prevention and management of LD-related intracranial infections involve multiple pieces of evidence, and medical staff should selectively apply the best evidence based on patient and clinical conditions to reduce the incidence of intracranial infections and improve medical quality.
ObjectiveTo establish a method that can eliminate the pollution of endogenous nucleic acid in the real-time quantitative polymerase chain reaction (PCR) reaction system, which can be used to reduce or eliminate the false positive rate of real-time PCR assay in detection of postoperative intracranial bacteria infection.MethodsAt first, eliminated the pollution of endogenous nucleic acid in the real-time PCR reaction system. Then, with mixed bacteria DNA as a template, multiple PCR was used to specifically identify the gram-negative bacteria. Meanwhile, evaluated the text line and sensitivity of the multiple PCR after eliminating pollution in detecting the DNA of the mixed bacteria.ResultsThe method established could quickly eliminate the pollution of endogenous nucleic acid in the real-time PCR reaction system, and it didn’t affect the Taq enzyme activity and the amplification efficiency in PCR system, with the minimum detection limit of 102 CFU/mL (Staphylococcus aureus and Pseudomonas aeruginosa), which was the same to the culture method. The enzyme cutting method had no significant effect on the activity and amplification efficiency of the enzyme in PCR system, It had no effect on PCR reaction system and primer specificity (Ct=32, ΔRn=200). However, the filtration method significantly reduced the PCR amplification efficiency (Ct=32, ΔRn=150).ConclusionsThis method can easily and rapidly eliminate the pollution of endogenous nucleic acid in the real-time PCR reaction system, and greatly reduce the false positive of PCR detection. It is able to timely and accurately diagnose the intracranial bacteria infection, which is significant for clinical testing.
目的:观察颅内感染急性期血清钠氯浓度的改变及其临床意义。方法:对160例颅内感染血清钾钠氯浓度进行动态监测。结果:颅内感染组低钠低氯发生率显著高于对照组(P＜0.05),结脑患者最高、化脑次之、病脑患者最低,但均高于对照组。各组间血清钾钠氯水平差异无统计学意义(P＜0.05),但与对照组比较有显著性意义差异(P＜0.05)。结论:成人颅内感染急性期大部分存在明显的低钠低氯血症,且不同病原感染所致低钠低氯的水平不相同,颅内感染低钠低氯与患者病情轻重成正相关。故动态监测血清钾钠氯有助于颅内感染的诊断和鉴别诊断以及病情轻重和预后估计。
目的 总结近十年来颅脑手术后颅内感染的发病率、病死率及病原菌谱，为制订预防颅内感染措施提供依据。 方法 检索中国学术期刊网全文数据库（CNKI）、万方数据库、重庆维普中文科技期刊全文数据库，并辅以文献追溯、手工检索等方法收集2001年－2012年国内正式刊物上公开发表的有关颅脑手术后颅内感染的中文文献。并对颅脑手术后颅内感染的流行病学调查资料进行Meta分析。 结果 共有27篇论文进入Meta分析，其中，25篇论文用于颅脑手术后颅内感染发病率的统计。共调查40 343例，发生颅内感染1 712例，感染率为4.24%。6篇论文提供了开颅术后颅内感染死亡的数据，在268例颅内感染患者中死亡39例，病死率为14.55%。15篇论文统计显示，颅内感染细菌培养阳性率为54.48%；15篇论文给出细菌培养结果，其中金黄色葡萄球菌占23.16%，表皮葡萄球菌占17.85%，铜绿假单胞菌占8.85%，大肠埃希菌占8.70%。 结论 国内颅脑手术后颅内感染以G+球菌为主，病原菌分布相对集中，临床上应予以重视。
ObjectiveTo analyze the clinical characteristics of acquired immune deficiency syndrome (AIDS) complicated with intracranial infection and to explore the nursing countermeasures. MethodsWe retrospectively analyzed the clinical features, laboratory examination indexes, and nursing methods of 12 AIDS patients complicated with intracranial infection between January and December 2010. ResultsIn the 12 patients, 8 were male, 4 were female; 11 were married and 1 was unmarried. The first symptom of headache occurred in 8 patients, and feverin 4 patients. Detection of HIV-1P24 antigen in all the 12 patients with HIV was positive for nucleic acid analysis. After treatment and symptomatic care, 3 cases were cured, 3 quit the treatment voluntarily, 2 improved patients were transferred to a higher-level hospital, 3 patients were readmitted to our hospital after improvement of the situation, and 1 patient died. ConclusionThe most common symptom of AIDS was neural disease. The diagnosis should be based on clinical manifestations, and the epidemiological data should be used as reference. At the same time, attention should be paid to the admission assessment and good occupation protection, health education promotion, improvement of patients' quality of life, and reduction of the incidence of complications and mortality rate.
