    Emphysematous cystitis (EC) is a rare form of complicated urinary tract infection, its characteristic feature being gas within the bladder wall and lumen. Patients with EC present with variable clinical manifestations ranging from asymptomatic to severe sepsis. EC is typically observed in elderly women with severe diabetes mellitus. Escherichia coli and Klebsiella pneumoniae are often isolated from urine cultures. Imaging methods, such as plain conventional abdominal radiography and computed tomography, are pivotal for obtaining a definitive diagnosis of EC. Most cases can be treated with a combination of antibiotics, bladder drainage and glycemic control. EC is potentially life-threatening, with a mortality rate of 7%. Early medical intervention can contribute to achieving a favorable prognosis without the need for surgical intervention. In this review, we provide a comprehensive description of the clinical characteristics of EC.

    Objective H. pylori infection in children has a high prevalence worldwide. The disease can cause progressive gastric mucosal inflammation, as verified in animal models. However, data from large-scale clinical studies are limited.
    Methods We examined 1,634 Chinese children with upper gastrointestinal discomfort using endoscopy. The clinical and pathological data of the patients were analyzed.
    Results A total of 524 (32.1%) patients were infected with H. pylori, and the prevalence of H. pylori infection increased with age. The H. pylori-infected patients exhibited a significantly higher prevalence of active inflammation (26.9% vs. 4.1%), lymphoid follicle formation (18.5% vs. 4.6%) and marked lymphocyte infiltration (19.7% vs. 5.6%). The H. pylori-infected patients also exhibited a significantly higher prevalence of moderate to marked chronic superficial gastritis (41.9% vs. 9.2%) and moderate chronic atrophic gastritis (21.7% vs. 2.6%) than the uninfected patients (p<0.01).
    Conclusion H. pylori infection is associated with the degree of gastric mucosal inflammation and the severity of different types of chronic gastritis.

    Objective The optimal medication therapies are recommended in patients with coronary artery disease even after the coronary revascularization. However, the information of optimal medical therapy in dialysis population is scant. We assessed the efficacy of statin on the clinical outcomes after Sirolimus-eluting stent (SES) implantation in patients with and without dialysis.
    Methods and Results We analyzed date from 843 consecutive patients who successfully treated with SES in our institution between August 2004 and November 2006. Among patients, 96 patients (11.4%) were undergoing dialysis. In non-dialysis patients, 405 patients (54%) were treated with statin at hospital discharge. In dialysis patients, only 16 patients (17%) were treated with statin. In non-dialysis patients, mortality rate was significantly lower in patients treated with statin than those without statin (4.4% vs. 13.9%, p<0.0001). While in dialysis patients, mortality rate was similar between patients treated with and without statin (56.3% vs. 57.6%, p=0.86). After adjusting for confounders, the hazard ratios for mortality were 0.39 (95% confidence interval (CI), 0.14-0.99; p=0.047) in non-dialysis patients and 1.79 (95% CI, 0.39-7.86; 0.45) for dialysis patients. The interaction probability between statin use and dialysis for mortality was 0.016.
    Conclusion The use of statin may have beneficial effect on reducing mortality rate in patients after SES implantation in non-dialysis patients. However, such favorable effect was not observed in dialysis population.

    Objective Primary bone lymphoma is a rare disorder, accounting for less than 1% of all cases of malignant lymphoma. Primary bony diffuse large B-cell lymphoma (PBDLBCL) is the most common histological type. In our study, a favorable response and lower risk of emergent surgery were observed following the administration of systemic chemotherapy with or without rituximab.
    Methods Patients diagnosed with malignant lymphoma at our hospital between 2000 and 2011 were evaluated for PBDLBCL. Pertinent data, including the clinical presentation, histological type, treatment modalities, long-term outcome, survival curve and prognostic factors, were analyzed.
    Results Twenty-four patients with a median age of 63 years were diagnosed with PBDLBCL. A complete response (CR) was achieved in 58.4% (n=14) of the patients. With treatment of the disease, nine of 10 patients with initially impending pathological bone fractures ultimately did not undergo surgery. The median follow-up duration was 48 months. Two patients experienced disease relapse. In a Kaplan-Meier analysis, the 5-year overall survival (OS) and disease-free survival (DFS) rates were 66.7% and 77.8%, respectively. In the univariate analyses, the significantly favorable prognostic factors for OS were an International Prognostic Index (IPI) score of <3, an age of ≤60 years, a performance status with an Eastern Cooperative Oncology (ECOG) score of <2, a CR and chemotherapy ≥6 cycles. For DFS, a CR was the only favorable factor. In the multivariate analysis, a CR was the only independent factor for both OS and DFS.
    Conclusion Our study confirms the good prognosis of this rare disorder. Once a CR is achieved, even elderly patients may exhibit long-term survival, possibly obviating the need for surgery for less severe bone lesions.
