HPV lesions, recurrence tendency, and risk of malignant formation are primarily dependent on the person’s immunity level. GW recurrence is a major challenge in CA treatment. The aim of this study was to explore how lesional auto-transplantation (LT) can be used to treat CA and decrease its recurrence. Methods: We treated CA through the preparation and implantation of tissue from nine CA patients in our dermatology clinic. Transplantation of small pieces of HPV lesions to the subcutaneous fat of the inguinal region was carried out with the help of a simple surgical method under local anesthesia. Patients were followed up for six to eight months. We searched PubMed and the Web of Science for treatment options for CA to compare our treatment method recurrence rate with existing treatment options. Results: During three months of follow-up, seven patients experienced no recurrence of condyloma lesions, while two patients experienced recurrence of small lesions of condyloma acuminatum. The recurrence rate of CA once treated by auto-transplantation was relatively low compared to other CA treatment options. Conclusions: Transplantation of HPV lesions to the inguinal area reduces the recurrence rate in sexually active individuals. The 2/9 recurrence after implantation could be due to poor hygiene, sexual relationships or immune factors.展开更多

This is not only because of the virulence of the spirochete which causes the infection but also because of its vertical transmission rate and the potential severe adverse complications/morbidity that can result from its transmission to the fetus. Although the incidence of maternal syphilis and its fetal sequalae in low-income countries has been considerable for several years, the disease has been almost non-existent in high income countries with wide antenatal screening coverage and effective treatment programmes for Syphilis. The recent alarming increase in the incidence of maternal syphilis in high income countries has spawned a renewed public health interest in the infection, with several countries updating and strengthening public health guidance in an attempt to stem this dramatic trend. This is a short clinical update for the practising obstetrician on how to manage the antenatal patient with a positive syphilis screening test.展开更多

Methods: Tricolor and bicolor immunofluorescentstaining antibody of cell surface antigen and intracel-lular IL-2, IL-4, IL-12, IFN-Y in CD4^+ and CD8^+ T-lymphocytes from 20 patients with CA were performedand followed by flow cytometry. Results: The number of CD3^+T, CD4^+T-lymphocytescells and CD4^+/CD8^+T cells ratio were significantlydecreased(P<0.01) in patients with CA Compared tocontrols, and IL-2, IL-12, IFN-γ production in CD4^+Tcells was decreased(P<0.01), IL-4 and IFN-γ produc-tion in CD4^+T cells was not significantly different (P>0.05), while IL-2 and IL-12 production in CD8^+Tc cellswas decreased (P<0.01), whereas IFN-γ and IL-4 pro-ducing in CD4^+T cells were of no significantlydifference(P>0.05). Conclusions: There was an imbalance of T lympho-cyte subsets, Th1/Th2 cytokines and Tc1/Tc2 in theperipheral blood of CA patients, which may play animportant role in the pathogenesis and progression ofCA.展开更多

Results: Upon electron microscopy, the most characteristic feature of the lesions important for diagnosis, was the presence of distinct perinuclear vacuolizations, or so-called koilocytes, among some epithelial cells. These cells possessed hyperchromatic nuclei, swollen mitochondria, dilated endoplasmic reticulum and dissolved glycogen. There were interchromatin granules and perichromatin granules in some nuclei. Moreover some virus particles were also seen in the nuclei of some infected cells. Conclusions: The ultrastructural findings may be used to histopathologically explain the pathogenesis and mechanism of this disease, and it is helpful for diagnosis of CA .展开更多

Methods: Flow cytometry (permeabization andstaining procedure with conjugated antibodies) wasused. Results: We observed that the expression of Fasprotein on CD4^+ T lymphocyte subset of CA patientswas significantly higher than that of healthy controls(P<0.01). Conclusions: Increased expression of Fas proteinon CD4^+ T lymphocyte subset may be a cause of de-creased percentage of CD4^+ T lymphocyte subset. Thisinduces the increased ratio of CD4^+/CD8^+.展开更多
