  • 简介:AbstractMalignant pleural mesothelioma (MPM) is a rare and aggressive malignant disease. Currently, the platinum doublet of pemetrexed and cisplatin is the standard first-line treatment for unresectable MPM. However, recent promising results of immunotherapy have markedly changed the landscape of MPM treatment. Further, the ongoing innovative therapeutic strategies are expected to expand the range of treatment options; however, several questions remain unanswered. First, establishing predictive biomarkers with high potency is urgently needed to optimize the patient selection process. Second, further exploration of the combination algorithm is expected to unveil more effective and safe regimens. Moreover, other dilemmas, such as the resistance mechanism of immunotherapy and the role of immunotherapy in perioperative settings, still warrant further exploration.

  • 简介:AbstractIntroduction:Malignant syphilis (MS) is a rare and severe variant of secondary syphilis that is frequently associated with HIV infection. The clinical impact of HIV and syphilis co-infection is bidirectional, and the presence of MS is associated with acute HIV infection. Clinically, MS is characterized by nodular and ulcerative lesions affecting the trunk and extremities, which are covered with thick crusts. The treatment of choice for MS remains benzathine penicillin G. Herein, we report a case in which MS was the initial presentation of HIV infection.Case presentation:A 35-year-old male patient came with the chief complaint of extensive erythematous nodular rash for the past one month, with notable ulceration on some lesions with annular configuration along with fever and malaise. Based on the abovementioned clinical, laboratory, and histopathologic findings, the patient was diagnosed with MS and HIV. The diagnosis was established based on histopathological examination and syphilis serological testing.Discussion:Cutaneous disorders are a frequent presenting feature of HIV infection. The clinical manifestations of syphilis in immunosuppressed patients are often severe and/or atypical. The patient was then treated with weekly intramuscular administration of 2.4 million units of benzathine penicillin G for 3 weeks and achieved rapid and significant clinical improvement, with no Jarisch-Herxheimer reaction.Conclusion:Co-infection with syphilis and HIV alters the course of both diseases, and most HIV-infected patients with syphilis have typical disease manifestations associated with decreased CD4+ T-cell counts.

  • 简介:AbstractObjective:To review the role of adjuvant hyperbaric oxygen therapy (HBOT) in the treatment of malignant otitis externa (MOE).Data sources:PubMed, Scopus, Web of Science, Science Direct, and Cochrane Library were searched for the following concepts: "hyperbaric oxygen" and "malignant or necrotizing otitis externa."Methods:Studies were included if they contained (1) patients with reported evidence of MOE, (2) employment of adjuvant HBOT, (3) details on patients’ medical condition, and (4) documented survival outcomes. Extracted information included patient demographics, underlying medical conditions, infectious etiology, signs and symptoms, medical and surgical treatments, duration of medical treatment, mean follow up time, HBOT setting, number of HBOT sessions, complications, survival rate, and all-cause mortality.Results:A total of 16 studies comprising 58 patients (mean age 68.0 years) were included. Diabetes was present in 94.7% of cases and Pseudomonas spp (64.3%) was the most common infectious agent. Cranial nerve VII was involved in 55.2% of cases. Overall, the disease cure rate with adjuvant HBOT was 91.4% and all-cause mortality was 8.6%. Among those who had cranial nerve VII involvement, 72.0% had return of function and 93.8% of them survived.Conclusion:HBOT may be an effective treatment option for refractory or advanced MOE but its efficacy remains unproven due to lack of strong scientific evidence. However, its therapeutic value should not be underestimated given good results and few adverse events reported in this study.

  • 简介:AbstractLong noncoding RNAs (lncRNAs) have recently been discovered and are increasingly recognized as vital components of modern molecular biology. Accumulating evidence shows that lncRNAs have emerged as important mediators in diverse biological processes such as cell differentiation, pluripotency, and tumorigenesis, while the function of lncRNAs in the field of normal and malignant hematopoiesis remains to be further elucidated. Here, we widely reviewed recent advances and summarize the characteristics and basic mechanisms of lncRNAs and keep abreast of developments of lncRNAs within the field of normal and malignant hematopoiesis. Based on gene regulatory networks at different levels of lncRNAs participation, lncRNAs have been shown to regulate gene expression from epigenetics, transcription and post transcription. The expression of lncRNAs is highly cell-specific and critical for the development and activation of hematopoiesis. Moreover, we also summarized the role of lncRNAs involved in hematological malignancies in recent years. LncRNAs have been found to play an emerging role in normal and malignant hematopoiesis, which may provide novel ideas for the diagnosis and therapeutic targets of hematological diseases in the foreseeable future.
