An Internet portal site Nurscape(R) for professional nurses was developed and evaluated. CyberNurse an interdisciplinary team of nursing academic faculty, physician and vendor personnel played an important role as an advisory committee for system design and content provision. The Nurscape(R) site was developed through the systematic approach of interaction among the CyberNurse, contents team, and technical team. Three approaches were used for a formative evaluation; 1) system evaluation including user testing and technical testing, 2) focus group survey for contents evaluation, and 3) analysis of the users' characteristics using the user registration information. Based on the data collected from the three different Internet environments (LAN, ADSL, Modem), it was found that the average access time and network status showed the corresponding differences in the latency of the network tested, but have been steady and consistent to use. And from the group survey some operational issues were found. In the user analysis the 20-30 generation nurses covered 94% of user, and clinical nurse working in the hospital and student nurse were active information seeking groups in Internet. However special nurse such as public health and home health nurse was the main group in community health area.

We report an unusual case of primary extranodal non-Hodgkin's lymphoma combined with sinusitis in an AIDS patient. A 39-year-old male presented with sinusitis as initial manifestation. A nasal endoscopy revealed nasal polyposis with mucopurulent discharge in both middle meatus and paranasal sinus (PNS) CT scans demonstrated pansinusitis without lamina papyracea or skull base defect. He received antiretroviral and antibiotics therapy due to low CD4 count representing immunocompromised state. The patient was not followed up for observation and he returned with reduced right visual acuity and diplopia, and proptosis after 6 months. A PNS CT scan showed bilateral sinonasal polyposis with pansinusitis and soft tissue density in the right orbit and frontal lobe through bone defect of lamina papyracea and skull base. Endoscopic sinus surgery for orbital decompression and biopsy of intraorbital mass was performed under general anesthesia. The mass was infiltrated into orbital contents and was confirmed as an diffused large B-cell lymphoma with anaplastic variant. The patient received radiotherapy because his general condition was poor. Proptosis and ocular pain were decreased; however, he complained of a persistent headache. Brain CT and MRI showed diffused parenchymal edema around brain abscess in the right frontal lobe. Stereotactic evacuation of the right brain abscess was performed. He has no specific complaints for the last 14 months and antiretroviral therapy is concluded at the present.

Although most of the maxillary sinus retention cysts are asymptomatic, a few of them increase in size and cause symptoms. However, they rarely erode bony walls nor protrude into the inferior meatus. I present 2 cases with maxillary sinus retention cysts protruding into the inferior meatus by making a large defect on the medial wall of the maxillary sinus.

Olfactory neuroblastoma is a rare malignant tumor of the nasal cavity arising from the olfactory neuroepithelium. It usually present as a polypoid mass in the superior nasal cavity including the cribriform plate, superior turbinate, and superior portion of nasal septum. The development of olfactory neuroblastoma outside of the region, in which olfactory epithelium exists, is exceedingly rare. In this report, we present an interesting case of an isolated sphenoid sinus olfactory neuroblastoma with a brief review of the literature.

Pemphigus vegetans is a rare variant of pemphigus vulgaris and is characterized by vegetating lesions in the inguinal folds and mouth and by the presence of autoantibodies against desmoglein 3. Two clinical subtypes of pemphigus vegetans exist, which are initially characterized by flaccid bullae and erosions (the Neumann subtype) or pustules (the Hallopeau subtype). Both subtypes subsequently develop into hyperpigmented vegetative plaques with pustules and hypertrophic granulation tissue at the periphery of the lesions. Oral administration of corticosteroids alone does not always induce disease remission in patients with pemphigus vegetans. We report here on a 63-year-old woman with pemphigs vegetans. She had a 2-year history of vegetating, papillomatous plaques on the inguinal folds and erosions of the oral mucosa. The enzyme-linked immunosorbent assay was positive for anti-desmoglein 3, but it was negative for anti-desmoglein 1. She was initially treated with systemic steroid, but no improvement was observed. The patient was then successfully treated with a combination of systemic steroid and dapsone with a good clinical response.
