Recently, one of the most popular applications on the Internet is the social networking, such as, Facebook and Twitter. Finding resources using recent Peer-to-Peer (P2P) schemes in a social network ...has limits, such as distance problem between peers etc. So, in this paper, we present an efficient social P2P management scheme based on interesting keywords. We compare our proposal with the recent P2P scheme to evaluate the interesting keyword based P2P.
In this paper, we focus on the scheme which supports mobility for 6LoWPAN sensor devices. We adopt Proxy Mobile IPv6 protocol to provide mobility for low power 6LoWPAN sensor devices. We also ...implement a testbed of the mobile healthcare system using our proposed mechanism.
Steroids are used in conventional treatment of atopic dermatitis (AD) and they are very effective for improving the symptoms, but they also have several complications. Many studies have reported that ...short-term use of cyclosporine (CsA) is effective for severe AD as a substitute for steroid. However, there are very few studies on the long-term use of CsA for AD in the Korean population.
The purpose of this study was to investigate whether long-term CsA therapy is effective and safe for treating AD.
We performed a retrospective study of the patients with AD and who were treated with CsA at Kyung Hee Medical Center between January 2001 and February 2008. Among 147 patients, 61 received CsA treatment for more than 6 months. To evaluate the efficacy of CsA treatment, the objective SCORAD was checked for all 61 patients at every visit. Extensive laboratory tests were performed every two months to assess the safety of treatment.
The mean duration of CsA treatment was 13.5+/-8.4 months and the mean initial dose of CsA was 2.7+/-0.9 mg/kg/day. The mean objective SCORAD values significantly decreased from 34.1+/-11.2 at baseline to 11.4+/-10.7 after 6-month of CsA treatment (p<0.05). A significant decline of the SCORAD score was observed starting from 1-month of CsA treatment. The mean duration of remission was 4.5+/-2.9 months. A total of 13 adverse events in 10 patients were recorded during the study period. One patient dropped out due to renal dysfunction. Elevation of peripheral blood pressure was noted in 8 patients. Three patients complained of gastrointestinal troubles, and one patient had hypertrichosis, but the problems of these 4 patients were mild and easily treated.
We suggest that long-term, low-dose CsA treatment is safe and effective for patients who suffer from AD.
This paper suggests a new ontology approach to search for the targeted contents easily including the several technical issues as well as the related standard status.
IPTV is defined as multimedia services, such as TV, video, audio, text, graphics, and data, delivered over IP-based networks managed to support quality of service (QoS), quality of experience (QoE), ...security, interactivity, and reliability. Those services are now expanded to mobile and wireless networks. This paper illustrates what technical challenges to be considered for IPTV seamless service in wireless environment. Given the critical role of QoS/QoE in the technology's widespread adoption, this paper also proposes efficient system architecture to support QoS/QoE for IPTV seamless service in wireless environment.
Topical application of the antihistamines commonly leads to sensitization for patients, but skin reactions provoked by their systemic use are very rare. The antihistamines cetirizine and hydroxyzine ...are piperazine derivatives, on the structural basis of an ethylenediamine, but the cross-reactions between the 2 have rarely been reported. A 44-year-old man visited because of the generalized morbilliform eruptions with pruritus over his whole body, after intake of hydroxyzine (Ucerax) and azelastine (Azeptine), administered during a 2-day period for chronic urticaria. Previously, he had presented the same cutaneous reactions after oral administration of cetirizine (Lotec). Oral challenge tests performed with cetirizine and hydroxyzine led to the same cutaneous reactions. He was given the diagnosis of drug eruption from cetirizine and hydroxyzine, which suggests that there were cross-reactions among cetirizine, hydroxyzine, and ethylenediamine.
Elephantiasis nostras verrucosa (ENV) is a rare clinical condition associated with chronic non-filarial lymphedema caused by bacterial or non-infectious lymphatic obstruction. A variety of ...etiologies, including infection, tumor obstruction, trauma, radiation, chronic venous stasis, congestive heart failure, and obesity, can lead to chronic lymphatic obstruction and edema. Mossy papules, plaques, and cobblestone-like nodules are clinically impressive features of ENV, but biopsy reveals only moderately abnormal findings such as pseudoepitheliomatous hyperplasia, dilated lymphatic spaces, fibrous tissue hyperplasia, and chronic inflammation. We present a case of ENV in a 67-year-old man with a 10-year history of multiple nodules and verrucous plaques on both feet. Microbiology ruled out a filarial infection. Nodule biopsy revealed pseudoepitheliomatous hyperplasia, marked dermal fibrosis, and a chronic inflammatory infiltrate. No evidence of carcinoma was identified. Both venous stasis and recurrent cellulitis could contribute to the dermal fibrotic changes of the lesions. However, before the recurrent cellulitis, he did not have any nodular lesions on his feet despite a 10-year history of venous disease. Therefore, this case suggests that venous stasis alone cannot produce the fibrotic nodular lesions of ENV.
An amelanotic malignant melanoma is characterized by little or no pigment. It is frequently misdiagnosed because it is a rare entity in general, and because of its unusual clinical features. ...Liposarcoma is one of the most common adult soft tissue sarcomas. We encountered a case of amelanotic melanoma with a concurrent liposarcoma. A 68-year-old man presented with a single, 1.5x1.5 cm round erythematous, eroded nodule on the left heel. A biopsy specimen showed atypical, pleomorphic tumor cells with little melanin pigment. The tumor cells were positive for S-100, HMB-45 and negative for cytokeratins. These findings were consistent with amelanotic melanoma. On positron emission tomography/computed tomography (PET/CT), a hypermetabolic lesion was found in the left buttock. This lesion was excised and diagnosed as a well-differentiated liposarcoma. An association between sarcomas and other primary malignancies has been reported. However, an association between melanoma and liposarcoma is rare.
