The threat of pandemic influenza has focused attention and resources on virus surveillance, prevention, and containment. The World Health Organization has strongly recommended the use of the antiviral drug, Oseltamivir (Tamiflu(R)), to treat and prevent pandemic influenza infection. In recent years, there have been case reports of vestibulocochlear events during or after oseltamivir treatment, other countries. Oseltamivir is generally well-tolerated and its most frequent adverse effects include nausea and vomiting, diarrhea, and abdominal pain. Up to now, bilateral vestibular hypofunction after oseltamivir medication has not been reported. Herein, we report a very rare case of a 36-year-old female with bilateral vestibular hypofunction following oseltamivir medication.

PURPOSE: Subacute sclerosing panencephalitis (SSPE) is a neurodegerative disease due to persistent measles virus infection. We investigated the role of programmed death-1 (PD-1) molecule which is related with chronic viral infection in developing SSPE in mouse. METHODS: We adopt the PD-1-/-, PD-1-/+, and wild type BALB/c 3 week old mice to make an animal model of SSPE by injecting measles virus (SSPE strain) intraventricularly. Three months after infusion of virus, the mice were sacrificed and examined if the typical pathologic lesions had been progressed. The sera were collected from each group of mice and the serum level of IL-21 was measured with ELISA kit. RESULTS: The necrotic lesions on white matter and gliosis were found in focal areas in wild type BALB/c. The extent of lesion was smaller in heterotype BALB/c. Scanty lesions were found in PD-1-/- mice. The sera level of IL-21 was not elevated in all three groups. CONCLUSION: Our data suggest that the PD-1 molecule may play a role in persistent viral infection.

Multiple cerebral infarctions coexisting with peripheral artery occlusion have been rarely reported and occur only in specific conditions. Also, the characteristics of thrombosis related to the outbreak of the coronavirus disease 2019 (COVID-19) have been observed and studied recently. We report a case of concurrent multiple cerebral infarctions and peripheral embolism in a patient with a recent history of COVID-19 infection. A 62-year-old male patient who had recently been infected with COVID-19 presented to our emergency department with left hemiparesis. Supportive treatments were given post the diagnosis of multiple cerebral infarctions in the right cerebral hemisphere. During the supportive treatments, motor weakness was seen in the right upper extremity. Computed tomography revealed thrombi in the right axillary, brachiocephalic, and brachial arteries. The patient was already taking antiplatelet and anticoagulant agents and had no other underlying disease to develop such occlusions except his recent history of COVID-19 infection. We checked his laboratory tests for coagulation profiles throughout the hospitalization to verify a possible cause. We believe that large thrombi formation due to COVID-19 can simultaneously cause embolism in the cerebrum and peripheral regions. This pathology can result in symptoms that could make diagnosis difficult, delaying treatment decisions. This report, therefore, suggests that it is necessary to take into account a patient’s history of COVID-19 infection in such situations, especially when the patient presents with symptoms of a stroke.

Bilateral sudden sensorineural hearing loss (SSNHL) is rare and usually indicates a serious systemic pathology. We describe an unusual case of bilateral SSNHL caused by sepsis. A 28-year-old female complained of acute-onset bilateral hearing impairment; in addition to otological symptoms, she had a systemic condition that met the criteria for sepsis. We performed a physical examination and laboratory tests to diagnose sepsis. Pure tone audiogram and videonystagmography were performed to evaluate the otological symptoms. Intravenous antibiotics and high-dose methylprednisolone were prescribed for treatment, and audiogram was repeated during that period. The fever subsided and the vital signs were stabilized. The electrolyte imbalance and abnormal urine parameters became normal. Hearing gradually recovered to a normal level on day 7 of hospitalization. In conclusion, sepsis should be considered as a cause of SSNHL. When conducting a detailed examination of patients with bilateral SSNHL, the clinician should consider systemic disease.

Behcet's disease is a systemic vasculitis, characterized by recurrent oral aphthous ulcers, recurrent genital ulcers, skin lesion, and ocular involvement. Monoclonal antibody to the tumor necrosis factor-alpha (TNF-alpha) is considered as a possible therapeutic approach to achieve clinical improvement, preventing relapse in Behcet's disease refractory to conventional anti-inflammatory drugs or immunosuppressive durgs. We report the use of infliximab, which is one of the TNF-alpha monoclonal antibodies, in a 17-year-old girl with Behcet's disease exhibiting severe mucocutaneous, ocular and neurological involvement refractory to standard treatment.

BACKGROUND: The morphological characteristics of hepatocytes transplanted into the spleen have been studied. However few attempts has been made to determine the expression of genes in intrasplenically transplanted hepatocytes. The aim of this study was to explore whether the pattern of expression of albumin gene in intrasplenically transplanted hepatocytes is similar to that in adult liver, resulting in the long-term expression of this hepatocyte-specific gene. METHODS: Hepatocytes isolated from liver of syngeneic Fischer 344 rats and transplanted into the spleen of rats from the same strain survived for 12 months in the absence of immunosuppressive drugs. Microscopic examination of intrasplenic hepatocytes and Northern blotting for albumin gene expression of RNA extracted from liver and spleen was performed. RESULTS: Microscopy demonstrated that hepatocytes attached themselves only in the red pulp of the spleen and isolated hepatocytes preserved the fine structures characteristic of normal hepatic parenchymal cells. Throughout the 12 months period, intrasplenically transplanted hepatocytes expressed albumin mRNA. CONCLUSIONS: Intrasplenically transplanted hepatocytes represent a unique in vivo system of extrahepatic maintenance of hepatocytes. This novel transplantation system could be used to investigate hepatocyte engraft, proliferation and gene expression.

Herpes zoster oticus (HZO) is characterized by auricular vesicles, facial palsy and vestibulocochlear dysfunction. The 8th cranial nerve can be most frequently involved. Rarely, it may be associated with the involvement of 5th, 6th, 9th, 11th or 12th cranial nerve. However, only few cases of HZO involving vestibular nerve without facial nerve palsy have been previously reported. We experienced an unusual case of 38-year-old woman who presented with auricular vesicles, otalgia, and vertigo of whilrling nature but not with facial palsy. Vestibular evoked myogenic potential (VEMP) and caloric tests that were performed to determine which division of vestibular nerve was involved demonstrated that decreased responses in this case. We report a case of HZO involving superior and inferior vestibular nerve without facial palsy that was confirmed by VEMP and caloric tests with a review of literature.

PURPOSE: To assess the effect of a rectal enema on interfraction prostate movement in bone alignment (BA) for prostate radiotherapy (RT), we analyzed the spatial difference in prostates in a bone-matched setup. MATERIALS AND METHODS: We performed BA retrospectively with data from prostate cancer patients who underwent image-guided RT (IGRT). The prostate was identified with implanted fiducial markers. The setup for the IGRT was conducted with the matching of three fiducial markers on RT planning computed tomography images and those on two oblique kV x-ray images. Offline BA was performed at the same position. The coordinates of a virtual prostate in BA and a real prostate were obtained by use of the ExaxTrac/NovalisBody system, and the distance between them was calculated as the spatial difference. Interfraction prostate displacement was drawn from the comparison of the spatial differences. RESULTS: A total of 15 patients with localized prostate cancer treated with curative hypofractionated IGRT were enrolled. A total of 420 fractions were analyzed. The mean of the interfraction prostate displacements after BA was 3.12+/-2.00 mm (range, 0.20-10.53 mm). The directional difference was profound in the anterior-posterior and supero-inferior directions (2.14+/-1.73 mm and 1.97+/-1.44 mm, respectively) compared with the right-left direction (0.26+/-0.22 mm, p<0.05). The required margin around the clinical target volume was 4.97 mm with the formula of van Herk et al. CONCLUSIONS: The interfraction prostate displacement was less frequent when a rectal enema was performed before the procedure. A rectal enema can be used to reduce interfraction prostate displacement and resulting clinical target volume-to-planning target volume margin.
