1/523. Reactivation of herpes virus after surgery for epilepsy in a pediatric patient with mesial temporal sclerosis: case report.OBJECTIVE: This case report is presented to raise the awareness of the potential risk of reactivation of herpes simplex virus (HSV) encephalitis after intracranial surgery. CLINICAL PRESENTATION: The case of an 8-year-old male patient who suffered a reactivation of HSV encephalitis after undergoing amygdalohippocampectomy for complex partial seizures is reported. This patient had previously contracted HSV 1 meningoencephalitis at the age of 16 months. Six years later, a left amygdalohippocampectomy was proposed after the development of intractable partial epilepsy associated with left mesial temporal lesions. During the postoperative period, the patient suffered severe clinical deterioration with partial status epilepticus, aphasia, and hyperthermia, which resolved after intensive antiepileptic treatment supported by acyclovir. CONCLUSION: We advise prophylactic pre-, peri-, and postoperative treatment with acyclovir for patients with known histories of HSV encephalitis who undergo intracranial procedures.- - - - - - - - - - ranking = 1keywords = herpes simplex, simplex, herpes (Clic here for more details about this article) |
2/523. Disseminated herpes simplex virus infection in a renal transplant patient as possible cause of repeated urinary extravasations.Disseminated herpes simplex virus type 2 (HSV-2) infections are infrequent in patients receiving organ transplants, but usually have a poor outcome. We describe the case of a renal transplant patient who developed a disseminated HSV-2 infection with repeated urinary extravasations. The diagnosis was carried out using a multiplex polymerase chain reaction nested assay and it suggested HSV-2 as a possible cause of repeated urinary fistulas.- - - - - - - - - - ranking = 3.7660221241635keywords = herpes simplex, simplex, herpes (Clic here for more details about this article) |
3/523. Chronic herpes simplex virus type I glossitis in an immunocompromised man.herpes simplex virus (HSV) type 1 (HSV-1) infection of the tongue commonly accompanies acute primary herpetic gingivostomatitis. However, recurrent infection of the tongue is exceptional and is restricted to immunocompromised individuals. A 57-year-old man with corticosteroid-dependent chronic obstructive pulmonary disease and sciatica presented with a chronic median glossitis due to HSV-1. The main clinical and histological feature was massive necrosis of the entire mucosa. immunohistochemistry demonstrated a considerable amount of HSV gB, gC and gD envelope glycoproteins dispersed in the chorion. In contrast, HSV-1 dna was detected only in a limited number of epithelial cells using in situ hybridization. The extent of necrosis and the pattern of viral dna and envelope protein distribution represent unique features of median herpetic glossitis, which are not found in more common types of HSV infection.- - - - - - - - - - ranking = 3.1203289831278keywords = herpes simplex, simplex, herpes (Clic here for more details about this article) |
4/523. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.- - - - - - - - - - ranking = 0.0040834729949621keywords = ocular (Clic here for more details about this article) |
5/523. Latanoprost and herpes simplex keratitis.PURPOSE: To report three cases in which herpes simplex keratitis developed after initiation of latanoprost therapy. methods: Case report. RESULTS: One patient with a history of herpes simplex keratitis had recurrence of herpes simplex keratitis with latanoprost treatment, resolution when latanoprost was stopped, and another recurrence when rechallenged with latanoprost. A second patient with a history of herpes simplex keratitis had bilateral recurrence with initiation of latanoprost; antiviral therapy could not eradicate herpes simplex keratitis until the latanoprost was discontinued. The third patient with latanoprost-associated herpes simplex keratitis cleared with the discontinuation of latanoprost and start of antiviral therapy; reinstitution of latanoprost with prophylactic antiviral medication kept the cornea clear, but as soon as the antiviral suppression was discontinued, herpes simplex keratitis reappeared. CONCLUSION: Latanoprost, among its diverse pharmacologic effects, may mediate inflammation in the eye. prostaglandins may be a final common pathway for stimulating recurrence of herpes simplex keratitis. Clinicians should be aware of this possible association.- - - - - - - - - - ranking = 40.686183466187keywords = herpes simplex keratitis, simplex keratitis, herpes simplex, keratitis, simplex, herpes (Clic here for more details about this article) |
6/523. Isolated inferior rectus paresis secondary to a mesencephalic cavernous angioma.PURPOSE: To report a case of recurrent binocular, vertical diplopia presenting as an isolated, unilateral inferior rectus paresis occurring in a patient with a mesencephalic tegmental cavernous angioma. METHOD: Case report. A 30-year-old man with recurrent vertical diplopia underwent neuro-ophthalmic examination, laboratory examination, pharmacologic testing, and magnetic resonance imaging and angiography. RESULTS: magnetic resonance imaging disclosed a lesion in the mesencephalon consistent with a cavernous angioma. magnetic resonance angiography was negative. CONCLUSIONS: Isolated inferior rectus paresis is a rare phenomenon. This unique case involved a patient with recurrent inferior rectus paresis secondary to a mesencephalic cavernous angioma. The disparity between the extent of the lesion and the neuro-ophthalmologic consequences is remarkable.- - - - - - - - - - ranking = 0.0010208682487405keywords = ocular (Clic here for more details about this article) |
7/523. Interface fluid associated with diffuse lamellar keratitis and epithelial ingrowth after laser in situ keratomileusis.We report a case in which diffuse interface keratitis began 1 week after bilateral uneventful laser in situ keratomileusis (LASIK). A layer of fluid in the interface with epithelial ingrowth was noted in the left eye 20 days postoperatively. The same complication occurred in the right eye 5 months after LASIK. Dry-eye syndrome and steroid-induced intraocular pressure elevation occurred in this patient with pre-existing ocular hypertension. A long course of interface inflammation was resistant to topical steroids. Surgical removal of the epithelial ingrowth and drainage of the fluid, combined with medical treatment, resulted in resolution of the inflammation. The cytopathologic examination of the fluid showed epithelial cells without signs of inflammation. The clinical features of this case represent a new complication of LASIK.- - - - - - - - - - ranking = 0.62971690207411keywords = keratitis, ocular (Clic here for more details about this article) |
8/523. MR imaging of intraventricular silicone: case report.A 42-year-old man with human immunodeficiency viral infection developed cytomegaloviral retinitis that was complicated by retinal detachment and was treated with an intravitreous injection of silicone. Fifteen months later, magnetic resonance imaging revealed intraocular and intraventricular silicone. Signal intensity characteristics and chemical shifts of silicone in the two locations were identical.- - - - - - - - - - ranking = 0.0010208682487405keywords = ocular (Clic here for more details about this article) |
9/523. Histopathological findings in proliferative membrane from a patient with sarcoid uveitis.BACKGROUND: Sarcoid uveitis is occasionally accompanied by proliferative changes, such as retinal neovascularization and vitreous hemorrhage. Steroid administration, retinal photocoagulation, and vitrectomy may be indicated in such proliferative cases. CASE: A 19-year-old woman presented with proliferative sarcoid uveitis accompanied by recurrent vitreous hemorrhage. OBSERVATIONS: At the initial examination, bilateral vitreous opacity, retinal exudates, mild vitreous hemorrhage, retinal vasculitis, and neovascularization of the retina and optic disc were observed. Although prednisolone was administered and panretinal photocoagulation was performed several times, recurrent vitreous hemorrhage continued. Since the vitreous hemorrhage was not absorbed, pars plana vitrectomy and lensectomy were performed. After surgery, neovascularization and intraocular inflammation decreased, and the corrected visual acuity in the right eye improved to 20/50. Histopathologic analysis of the proliferative membrane removed during surgery revealed substantial neovascularization and numerous neutrophils in the vessels. CONCLUSIONS: Based on these findings, an inflammatory reaction as well as retinal ischemia were thought to be involved in the proliferative changes in this patient.- - - - - - - - - - ranking = 0.0010208682487405keywords = ocular (Clic here for more details about this article) |
10/523. Follicular large-cell lymphoma of the orbit: a clinicopathologic, immunohistochemical and molecular genetic description of one case.BACKGROUND: Follicular large cell lymphoma of the orbit is a very rare and aggressive lymphoproliferative disease of the ocular adnexa. In this study we analyzed the clinicopathologic characteristics of one patient, including the immunoglobulin gene rearrangement assay by means of polymerase chain reaction. CASE REPORT: A 71-year-old female underwent an incisional biopsy in the superior nasal quadrant of the left orbit following the occurrence of bilateral eyelid edema and ptosis. histology and immunohistochemistry revealed a follicular large cell lymphoma of the orbit. Computerized tomography aimed at staging the disease revealed a supraclavicular lymphoadenopathy approximately 0.5 cm in diameter. bone marrow biopsy was negative for lymphoma. The patient was classified as stage IV. She underwent a 10-week cycle of polychemotherapy (VP16, adriamycin, cyclophosphamide, vincristine, prednisone, bleomycin). Ten months after therapy, disease recurred at the cervical lymph nodes and the patient underwent a radiotherapy cycle of 4320 cGy with disease remission. At the time of writing, the patient presents a left axillary adenopathy on computerized tomography followup. CONCLUSION: Ophthalmologists should be aware of possible rare occurrences of follicular large cell lymphomas of the orbit. In this case the clinical outcome is always more aggressive than the more common MALT-type lymphoma, which usually exhibits benign behavior.- - - - - - - - - - ranking = 0.0010208682487405keywords = ocular (Clic here for more details about this article) |
