Acute Myeloradiculitis Associated with Herpes Simplex Virus Type 2 Presenting with Acute Flaccid Paralysis

We describe two patients with acute myeloradiculitis associated with herpes simplex virus type 2 (HSV-2). They were previously healthy and immunocompetent and had no history of herpes infection or rash. Myeloradiculitis manifested as an acute flaccid paralysis that primarily involved the conus medullaris and cauda equina. laccid paralysis can be caused by HSV-2 myeloradiculitis, and so early antiviral treatment should be considered.

Meningoencephalitis associated with Parvovirus B19 Infection in an Immunocompetent Patient / 고신대학교의과대학학술지

Parvovirus B19 (PVB19) infection is a rare cause of meningoencephalitis. A 53-year-old previously healthy woman presented with fever, headache, and multiple erythema on the both legs. Cerebrospinal fluid study revealed pleocytosis and elevated opening pressure and protein level. Brain MRI showed multiple, asymmetric, hyperintensity in the brain stem, basal ganglia, white matter, and gray matter. Anti-B19 IgM antibody and PCR for PVB19 were positive in serum. Clinician should consider PVB19 infection in any case of acute febrile illness with erythema and meningoencephalitis.

Serial MRI of Hypoxic Brain Damage after Hydrogen Sulfide Exposure

Hydrogen sulfide is a colorless gas and frequently lethal occupational hazard that causes tissue hypoxia with prominent neurological signs. Depending on the amount of exposure, many neurotoxic effects such as headache, disequilibrium, and loss of consciousness have been reported. However, a few address the brain MRI findings in hydrogen sulfide poisoning. We report serial brain MRI findings in a patient with hydrogen sulfide intoxication.

Biometric Risk Factors for Corneal Neovascularization Associated with Hydrogel Soft Contact Lens Wear in Korean Myopic Patients

PURPOSE: To investigate the biometric risk factors for corneal surface complications associated with hydrogel soft contact lens (SCL) fitting in myopic patients in Korea. METHODS: This is a retrospective case-control study. The records of 124 subjects (124 eyes) who wore SCLs on a daily basis were reviewed. Thirty-one patients (31 eyes) who were diagnosed with corneal neovascularization (NV) while wearing SCLs were included in the complication group. Ninety-three age- and sex-matched patients (93 eyes) who wore SCLs, who did not have corneal NV and who visited our clinic for correction of refractive errors were included in the control group. The degree of spherical equivalent, astigmatism and corneal base curve radius (BCR) were compared in both groups. RESULTS: Patients with NV exhibited poorer best corrected visual acuity and more myopia than controls (p = 0.008 and 0.006, respectively). In univariate analysis, highly myopic patients (-9 diopters [D] or higher) were more likely to experience NV (odds ratio [OR], 2.232; 95% confidence interval [CI], 1.602 to 3.105). High astigmatism (> or =2 D) increased the risk of complications (OR, 2.717; 95% CI, 1.141 to 6.451). Steep cornea, in which BCR was <7.5 mm, also raised the risk of complications (OR, 4.000; 95% CI, 1.661 to 9.804). Flat cornea was not a risk factor for the development of NV. CONCLUSIONS: High myopia, high astigmatism, and steep cornea seemed to be risk factors in the development of corneal NV in SCL wearers.

A Case of Syringocystadenoma Papilliferum of the Eyelid

PURPOSE: To report a case of syringocystadenoma papilliferum that presented as an eyelid nodule. CASE SUMMARY: A 37-year-old woman presented with a mass around the punctum in the right lower eyelid margin, which had developed several years earlier and was increasing in size. The mass was a light pinkish nodule consisting of a few smooth-surface papillary lobules. The pathologic findings of the specimen obtained from a shaving biopsy showed a papillary projection which was covered with epithelium and communication with duct-like structures showing glandular configuration in the deep portion of the lesion. EMA-positive cells were found at the invaginated epithelium, implying a glandular epithelial origin. GCDFP-15-positive cells were found in the deep portion of the lesion, implying apocrine differentiation. The findings were compatible with syringocystadenoma papilliferum. CONCLUSIONS: Syringocystadenoma papilliferum should be considered as a differential diagnosis of a solitary eyelid tumor.
