  • Endoscopic Sinius Surgery Combined with Middle and Inferior Meatus Fenestration for Fungal Ball Maxillary Sinusitis: A Randomized Controlled Trial

    Objective To compare endoscopic sinius surgery plus middle meatus fenestration with endoscopic sinius surgery plus middle and inferior meatus fenestration for fungus ball maxillary sinusitis. Methods Applying a prospective randomized controlled trial, 80 patients with fungal ball maxillary sinusitis from January, 2010 to March, 2011 were collected and then divided into two groups, including experiment (40 cases) and control groups (40 cases). The trial group received endoscopic sinius surgery plus middle and inferior meatus fenestration, which the control group received endoscopic sinius surgery plus middle meatus fenestration. Then a follow-up was conducted from the end of surgery to February 28th, 2013. All patients took subjective and objective assessment before and after the surgery, including VAS, SNOT-20, Lund-Mackay CT system scores and Lund-Kennedy endoscopic mucosal score. Results with the trial group was superior to the control group in VAS score, SNOT rating and Lund-Kennedy mucosa score 6 months, 1 year, and 2 years after surgery (Plt;0.01). Lund-Mackay CT score of the control group was significantly higher than the trial group after 1 year of surgery (Plt;0.01). According to the Haikou standard to assess the efficacy of surgery, we found that the total effectiveness rate of the trial group (100.0%; recovery: 36 cases; improved: 4 cases) was higher than that of the control group (87.5%; recovery: 28 cases; improved: 4 cases), with a significant difference (P=0.021). Conclusion Endoscopic sinius surgery plus middle and inferior meatus fenestration with a lower reoccurrence rate is superior to endoscopic sinius surgery plus middle meatus fenestration for fungus ball maxillary sinusitis in clinical efficacy.

    【摘要】 目的 对季也蒙念珠菌感染患者的临床及微生物学特征进行分析,为临床诊治提供参考。 方法 收集2006年1月-2008年12月病原菌培养为季也蒙念珠菌的10例住院患者资料进行回顾性分析。 结果 季也蒙念珠菌感染患者存在多种基础疾病,大多数患者(8/10)有易感因素,其中7例使用广谱抗菌药物。10例中有8例为深部真菌感染。其临床表现与感染部位有关,主要累及泌尿道、呼吸道和皮肤软组织。多数深部感染患者(6/8)在感染前存在同部位细菌感染,部分患者(3/8)在相同部位还可分离出其他真菌。全部季也蒙念珠菌菌株对两性霉素B敏感,大多数菌株(9/10)对氟康唑敏感。仅1例患者因肺部感染、呼吸衰竭死亡,其余患者经氟康唑、伊曲康唑或特比萘芬等抗真菌药物治愈。 结论 季也蒙念珠菌感染多发生于有基础疾病、存在真菌易感因素者,感染部位多为原细菌感染部位,常合并其他细菌或真菌感染。部分菌株对氟康唑和伊曲康唑中敏或耐药,治疗应根据药敏进行选择。【Abstract】 Objective To analyze the clinical and microbiologic characters of candida guilliermondii to improve the clinical diagnosis and treatment. Methods The clinical data of 10 patients with candida guilliermondii infection diagnosed in our hospital from January 2006 to December 2008 were retrospectively analyzed. Results All the patients had several underlying conditions; eight patients had predisposing factors and seven patients were prescribed with broad-spectrum antibacterials. Eight patients had deep mycoses, whose clinical manifestation was associated with the infectious sites, mainly involved in urinary tract, respiratory tract and skin-soft tissues. Most deep mycoses (6/8) had prior bacterial infection at the candida guilliermondii infection site; some patients (3/8) had other fungous infection at the same time. All the strains were sensitive to amphotericin B; most fungous strains (9/10) were sensitive to fluconazole. One patient died of pulmonary infection and respiratory failure, and the others were cured by fluconazole, itraconazole or terbinafine. Conclusion Candida guilliermondii infection mainly occurs in patients with underlying conditions and predisposing factors. The infectious sites have prior bacterial infection and bacterial infection or fungous infection at the same time. Since some candida guilliermondii strains were not sensitive to fluconazole and itraconzole, drug sensitive test should be consulted.

  • The clinical analysis of 160 immunocompromised hosts with septicaemia

    Objective To explore the pathogens and clinical features of immunocompromised hosts with septicaemia.Methods The data including underlying diseases, peripheral blood granulocyte count, temperature at blood sampling, management and prognosis)of 160 immunocompromised hosts with septicaemia were analyzed retrospectively.Results 8 patients had twice septicaemia in hospital stay and 3 patients had plural pathogenic septicaemia.171 strains of microorganisms were isolated from blood cultured of 160 septic immuno- compromised hosts in which 156 strains (91.2%) were bacteria, 37 strains(21.6%) were gram positive cocci, 6 strains(3.5%) were gram positive bacilli, 113 strains (66.1%) were gram negative bacilli and 15 strains (8.8%) were fungi. Staphylococcus spp (17 strains) and Streptococcus spp (14 strains) were the predominant pathogens among gram positive cocci and Corynebacteria (5 strains ) were the main pathogen in gram positive bacilli while Escherichia coli (60 strains), Klebsiella pneumoniae (20 strains) and Pseudomonas aeruginosa (15 strains) were the most common bacteria in gram negative bacilli. There were 12 strains of Staphylococcus aureus among the 17 strains of Staphylococcus spp, all of them were methicillin sensitive (MSSA). 17 strains of Escherichia coli, 2 strains of Klebsiella pneumoniae and 1 strain of Klebsiella oxytoca produced ESBLs. Candida was the only pathogens of fungemia in this study in which 4 strains of Candida albicans and 11 strains of non-albicans Candida were detected. There were 120 patients(75%) with granulocytopeniain which 103 patients were agranulocytosis. 70% of the 160 paitents had hyperpyrexia. All patients received broad spectrum antibiotics therapy in the study while 58.8% received antifungal drugs at the same time. 20 patients died of septicaemia and 19 patients gave up therapy because of their conditions deteriorated.The overall improvement rate were 75.6%. Conclusions Bacteria are the main pathogens in septicaemia of immunocom- promised host and fungemia is increasing in recent years.Agranulocytosis is a risk factor of septicaemia in immunocompromised hosts. Hyperpyrexia is one of characteristic signs of these patients.

    Objective To explore the risk factors of invasive fungal infection ( IFI) in respiratory ward. Methods A multi-center, retrospective, case-control study was carried out. Patients from five general hospitals in Chongqing city, diagnosed as fungal infection, or whose respiratory specimens were fungal positive, were retrospectively screened for IFI. Patients with respiratory infection and colonization of nonfungal cases in the same period of hospitalization were enrolled as control. Results Thirty-four patients diagnosed with IFI and 50 patients diagnosed with bacterial infection were analyzed for the risk factors of IFI. The demographic characteristics of patients including age and gender were not different( P gt; 0. 05) , but hospitalization days, carbapenem antibiotic use, chemotherapy, deep venous catheterization, total parenteralnutrition( TPN) , neutropenia, and renal disfunction were different significantly between the IFI group and the control group. Multiple logistic regression analysis showed that carbapenem antibiotic use ( OR = 6. 753) ,central venous catheterization ( OR = 5. 021) and TPN ( OR = 3. 199) were main risk factors of invasive fungal infection. Conclusion The carbapenem antibiotic use, central venous catheterization and TPN are risk factors for IFI in respiratory ward.
