1/146. Castleman disease presenting with ophthalmic signs and symptoms.PURPOSE: To describe a patient with multicentric Castleman disease who was initially examined with ophthalmic signs and symptoms. methods: Case report. A 71-year-old man was initially examined with swelling of both upper eyelids and diplopia of 2 months' duration. RESULTS: Medical evaluation and right axillary lymph node biopsy disclosed Castleman disease. Systemic corticosteroid treatment temporarily resolved signs and symptoms, but the patient died of recurrence with cytomegalovirus and aspergillus infection 10 months after initial examination. CONCLUSIONS: Multicentric Castleman disease is a rare but distinct disorder that may present initially with ocular signs and symptoms. This disease must be included in the differential diagnosis of orbital pseudotumor and lymphoma.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/146. Cytomegalovirus-induced syringosquamous metaplasia.An unusual case of syringosquamous metaplasia of the eccrine ducts caused by cytomegalovirus (CMV) is presented. The patient was hiv positive and had extensive excoriation of the perineum and vulva. biopsy revealed the presence of herpes simplex virus (HSV) inclusions in the necrotic exudate, a CMV vasculitis and extensive involvement of the eccrine ducts. In addition to containing typical CMV inclusions, the eccrine ducts showed proliferation and squamous metaplasia. Inclusions of HSV were not seen within the eccrine ducts by light microscopy or immunohistochemistry. The extensive proliferation with accompanying squamous metaplasia superficially can resemble an infiltrating squamous carcinoma, but this was not evident to a great extent in this case. To the best of our knowledge, our case represents the first of syringosquamous metaplasia of eccrine ducts caused by CMV infection.- - - - - - - - - - ranking = 1031.4858512668keywords = herpes simplex, simplex, herpes (Clic here for more details about this article) |
3/146. Neovascularization of the optic disc after highly active antiretroviral therapy in an AIDS patient with cytomegalovirus retinitis--A new immune recovery-related ocular disorder?A patient with AIDS and cytomegalovirus (CMV) retinitis developed a massive bilateral peripheral occlusive vasculopathy with a bilateral neovascularization of the optic disc five weeks after the introduction of highly active antiretroviral therapy (HAART). No associate cause of occlusive vasculopathy was found. Occlusive vasculopathy and optic disc neovascularization may be an immune recovery-related ocular disorder.- - - - - - - - - - ranking = 5keywords = ocular (Clic here for more details about this article) |
4/146. Fatal herpesvirus-6 encephalitis in a recipient of a T-cell-depleted peripheral blood stem cell transplant from a 3-loci mismatched related donor.Human herpesvirus-6 (HHV-6), like all the other herpes viruses, remains latent in host cells after primary infection but can be reactivated in immunocompromised patients causing fever, skin rash, bone marrow (BM) suppression, pneumonitis, sinusitis and meningoencephalitis. We describe the case of a man with chronic myelogenous leukemia who developed encephalitis associated with acute graft-versus-host disease two months after a T-cell-depleted mismatched peripheral blood stem cell transplant. Magnetic resonance images of the brain revealed multiple bilateral foci of signal abnormality. HHV-6 was the only pathogen detected in cerebrospinal fluid by PCR. Treatment with both ganciclovir and foscarnet was unsuccessful and the patient gradually deteriorated and died. Other cases of HHV-6 encephalitis after bone marrow transplantation are reviewed.- - - - - - - - - - ranking = 417.62385633985keywords = herpes (Clic here for more details about this article) |
5/146. optic disk neovascularization in a patient with cytomegalovirus retinitis associated with renal transplantation.PURPOSE: To report the development of optic nerve head neovascularization during the recovery phase of cytomegalovirus (CMV) retinitis in a renal allograft recipient. CASE REPORT: A 46-year-old male renal allograft recipient developed CMV retinitis seven months after transplantation. At the time of the diagnosis, the patient was being immunosuppressed with prednisone, cyclosporine, and azathioprine, and was treated with repeated intravitreal and intravenous ganciclovir. Six weeks after the initiation of therapy, optic disk neovascularization developed. This was confirmed by fluorescein angiography, which showed no areas of retinal capillary nonperfusion. At this stage, active retinal lesions were partially resolved. Apart from intraocular inflammation, no other cause of neovascularization was detected. Over the following six months, optic disk neovascularization regressed spontaneously without causing vitreous hemorrhage or visual loss. There was no recurrence of CMV retinitis during follow-up. CONCLUSION: optic disk neovascularization may develop in the healing phase of CMV retinitis in renal transplant recipients.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
6/146. Synchronous herpes simplex virus and cytomegalovirus esophagitis.Infective esophagitis is a rare disease, affecting mostly immunocompromised patients. Very few cases of a multiple viral infection have been reported. We present a case of combined cytomegalovirus (CMV) and herpes simplex virus (HSV) esophagitis in an 81-year-old female with extracapillary sclerosing glomerulonephritis treated for five months with steroids and chemotherapy. She died of septic shock. At autopsy, erosive and ulcerative esophagitis was found in the distal half of the esophagus. Slides were stained by HE, and the immunohistochemical avidin-biotin method was used to detect HSV and CMV infection. On histological examination of the esophagus, epithelial giant cells with intranuclear viral inclusions showing HSV immunopositivity were found at the margin of the ulcerations. giant cells with intranuclear inclusions with CMV immunopositivity were also found in the mesenchymal cells obtained from the ulcer bed. Long-term immunosuppressive therapy provoked an immune deficiency, evidenced by grave leukopenia and depletion of all bone marrow elements. diagnosis of HSV and CMV esophagitis is important to evaluate the risk of hemorrhage and esophageal perforation in esophagitis.- - - - - - - - - - ranking = 5157.4292563342keywords = herpes simplex, simplex, herpes (Clic here for more details about this article) |
7/146. Ocular side-effects from systemic HPMPC (Cidofovir) for a non-ocular cytomegalovirus infection.PURPOSE: To report a case of anterior uveitis and ocular hypotony during HPMPC treatment of a cytomegalovirus infection without ophthalmic involvement. methods: A 61-year-old bisexual white man with AIDS presented with moderate anterior uveitis and ocular hypotony after 8 weeks of intravenous HPMPC and oral probenecid co-treatment of a presumed recurrence of cytomegalovirus encephalitis. RESULTS: There was no evidence of an ocular cytomegalovirus infection. Cidofovir-related uveitis was diagnosed, and the HPMPC-probenecid co-treatment was switched to ganciclovir monotherapy. The ocular inflammation was successfully managed with topical steroids and mydriatics. CONCLUSIONS: This description of ophthalmic side effects from systemic HPMPC in the absence of ocular cytomegalovirus infection supports the hypothesis that anterior uveitis and ocular hypotony result from a direct interaction between the drug and the ciliary body.- - - - - - - - - - ranking = 10keywords = ocular (Clic here for more details about this article) |
8/146. Histopathologic findings in cutaneous cytomegalovirus infection.When cytomegalovirus (CMV) involves the skin, viral inclusions are typically present within mesenchymal cells, e.g., endothelial cells, fibrocytes, and sometimes within inflammatory cells, e.g., macrophages, in contrast to infection in other organs in which inclusions are usually present within ductal epithelial cells. Two cases of cutaneous CMV are presented, one showing prominent findings within eccrine ductal epithelium and the other revealing mostly endothelial cells affected by CMV. Due to the range of cytologic changes induced by CMV observed in these cases, there seem to be early, fully developed, and late cellular changes brought about by CMV analogous to how herpesvirus (varicella, zoster, simplex) induces different changes depending on its stage of infection.- - - - - - - - - - ranking = 213.7560847839keywords = simplex, herpes (Clic here for more details about this article) |
9/146. ganciclovir for the treatment of anterior uveitis.BACKGROUND: ganciclovir, administered systemically or intraocularly, is effective in controlling cytomegalovirus (CMV) retinitis in immunocompromised patients. The efficacy of therapy with this antiviral substance was investigated in an immunocompetent patient with CMV uveitis causing secondary glaucoma. methods: To identify the presence of an intraocular viral infection, anterior chamber taps to detect the intraocular synthesis of IgG antibodies and PCR testing were carried out. Clinically, the degree of intraocular inflammation and the intraocular pressure (IOP) values were monitored. During this time, the patient was treated systemically with ganciclovir administered orally and intravenously. RESULTS: The intraocular synthesis of IgG antibodies specific for CMV was found in two samples of aqueous humor, but negative for other viruses. PCR testing was negative for HSV, VZV and CMV at each time. During this time, the patient was treated systemically with ganciclovir administered either intravenously or orally. As a response to therapy with ganciclovir, the elevated IOP values decreased to normal and the intraocular inflammation declined. After cessation of ganciclovir administration, the inflammation and secondary glaucoma recurred. CONCLUSION: In this case of anterior uveitis presumably caused by CMV inducing secondary glaucoma, treatment with ganciclovir led to a decrease of the inflammation and normalization of IOP. It appears that continuous administration may be required to control the infection in an immunocompetent patient.- - - - - - - - - - ranking = 7keywords = ocular (Clic here for more details about this article) |
10/146. Monitoring four herpesviruses in unrelated cord blood transplantation.Cord blood transplantation, which has lower risk of graft-versus-host disease than bone marrow transplantation, might have higher risk of infections. A system to quantify four herpesviruses, CMV, human herpesvirus 6 (HHV6), EBV, varicella-zoster virus using the real-time PCR assay was established and applied for prospective viral load monitoring in three recipients undergoing cord blood transplantation. CMV and HHV6 were detected in peripheral blood from all three recipients, while EBV was detected in two. Varicella-zoster virus was not detected at all. At the peak of HHV6 or CMV, each patient showed virus-related symptoms. During the pre-transplant period, CMV dna was detected in two recipients who later developed CMV-related diseases. These observations indicate that our system is not only useful for managing herpesviruses infections in transplant recipients, but also a powerful method for clarifying the relationships between the viral load and clinical symptoms.- - - - - - - - - - ranking = 487.22783239649keywords = herpes (Clic here for more details about this article) |
