Splenic abscess is an unusual and potentially life-threatening disease. Due to the nonspecific clinical picture, it remains a diagnostic challenge. Splenic abscess should be suspected in febrile patients with left upper quadrant tenderness and leukocytosis, and diagnosis confirmed based mostly on imaging studies, microbiologic and / or pathologic evidence, or by response to antibiotic or antifungal treatment. We present 29 cases of splenic abscess treated in our hospital from 1990 to 2001. There were 18 male patients (62%) and 11 female patients (38%). Ages ranged from 4 to 85 years, with a median of 44 years. There were five pediatric patients (17%) and 24 adults (83%). The most common associated condition was leukemia. Most patients were immunocompromised (72%). The more common signs and symptoms were fever (90%), chills (41%), abdominal pain (31%), and leukocytosis (38%). Ultrasonography of the abdominal cavity was positive in 27 cases (93%); computerized tomography or magnetic resonance imaging was used in 26 patients (90%) and was positive in all patients. The abscess was solitary in 21 cases (72%) and multiple in eight cases (28%). Positive blood cultures were found in only seven patients (24%). According to the literature, the treatment of choice is still splenectomy, but in our study, the success rate of 75% with antibiotics alone indicates that antibiotic therapy should be considered an important alternative treatment modality in patients not suitable for percutaneous drainage and splenectomy.
Research on molecular mechanisms underlying the carcinogenesis of non-small cell lung cancer (NSCLC) may provide gene targets in critical pathways valuable for improving the efficacy of therapy and survival of patients with NSCLC. However, the molecular markers highly sensitive for the prognosis and treatment evaluation of NSCLC are not yet available. To explore candidates, we conducted an oligonucleotide microarray study with three pairs of NSCLC and normal lung tissue, and determined 8 differentially expressed genes including the Human MutT homologue (hMTH1), Surfactant protein D (SPD), Human hyaluronan binding protein 2 (HABP2), Crystalline-mu (CRYM), Ceruloplasmin (CP), Integrin alpha-11 subunit (ITGA11), Collagen type XI alpha I (COL11A1), and Lungspecific X protein (Lun X). Four lung cancer-related markers MUC-1, hTERT, hnRNP B1, and CK-19 were also incorporated for further analysis. The expression profiles of the twelve genes in seventy pairs of NSCLC tumor and normal lung tissue were then detected quantitatively by using membrane array and quantitative real-time PCR (qRT-PCR). The data of the membrane array and qRT-PCR were compared for consistency and the potential of these mRNA markers in clinical application. The results showed that membrane array and qRT-PCR obtained consistent data for the tested genes in both sensitivity and specificity (correlation coefficient 0.921, p<0.0001). For patients' clinicopathological characteristics, the overexpression of hMTH1, SPD, HABP 2, ITGA11, COL11A1, and CK-19 was significantly correlated with the pathological stage (p<0.05). In addition, the overexpression of hMTH1, SPD, ITGA11, and COL11A1 was correlated with lymph node metastasis and poor prognosis. This is the first report relating SPD to a prognosis marker for NSCLC. Moreover, the combined detection of these four mRNA markers by membrane array had a sensitivity of 89% and a specificity of 84% for NSCLC, significantly higher than these markers had achieved separately. In conclusion, we identified mRNA markers for NSCLC prognosis and therapy evaluation from differentially expressed genes determined by using microarray. Further studies are needed to collect the data of the mRNA markers used in clinical practice.
The consumption of a soup containing B. officinalis Hemsley resulted in dose-related toxic effects. Clinical toxicity consisted primarily of gastrointestinal symptoms and signs and hepatotoxicity. Hepatocellular liver injury rather than cholestatic liver injury was observed. Marked jaundice did not develop.
AgNOR method, which is rapid and easy to perform, may be a useful adjunct to flow cytometry, S phase fraction analysis and conventional cytology in the routine diagnosis of malignant pleural effusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
