BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.

2.Personal digital assistants: Essential tools for preparing dietetics professionals to use new generation information technology.
Nutrition Research and Practice 2007;1(1):42-45
Rapid integration of information technology into health care systems has included the use of highly portable systems-in particular, personal digital assistants (PDAs). With their large built-in memories, fast processors, wireless connectivity, multimedia capacity, and large library of applications, PDAs have been widely adopted by physicians and nurses for patient tracking, disease management, medical references and drug information, enhancing a quality of health care. Many health-related PDA applications are available to both dietetics professionals and clients. Dietetics professionals can effectively use PDAs for client tracking and support, accessing to hospital database or information, and providing better self-monitoring tools to clients. Internship programs for dietetics professionals should include training in the use of PDAs and their dietetics applications, so that new practitioners can stay abreast of this rapidly evolving technology. Several considerations to keep in mind in selecting a PDA and its applications are discussed.

Prader-Willi(PW)syndrome is characterized by obesity, hypotonia, mental retardation, hypogonadism, short stature, excessive eating and characteristic facial appearance. Diabetes mellitus has been considered a component of PW syndrome. Recently this syndrome is caused by the absence of paternally derived genes normally located on chromosome segment 15 q11-q13 or may be the result of maternal uniparental disomy with the absence of paternally derived 15 q11-q13 region. The developement of probes containing segments of DNA from chromosome region 15 q11-q13 provides the oppotunity to confirm the diagnosis of PW syndrome by fluorescence in situ hybridization(FISH). We experienced a 15-year-old boy of PW syndrome with diabetes mellitus, who revealed mental retardation, hypogonadism, obesity and microdeletion of chromosome 15 q11-q13 comfirmed by FISH.

Ketotifen, a benzocycloheptathiophene, has an orally effective antiallergic as well as antihistaminic properties. In pervious studies, Ketotifen has shown encouraging results on patient with allergic rhinitis, either perennial or seasonal. 39 patients with allergic rhinitis had been treated with Ketotifen 1 mg twice daily for 8 weeks. And we obtained following results. 1) The efficacy rate in sneezing attack was 73.5%, in nasal discharge 71%, in nasal obstruction 58%. 2) Some improvements in at least one of three-major symptoms were noted within 1 week in 30.7%, within 2 weeks in 55.8%, within 3 weeks in 66.7%, within 8 weeks in 87.2%. 3) Physical findings such as colour, swelling of turbinate, character of rhinorrhea were not improved significantly. 4) Side effect was observed only in one patient with abdominal pain and diarrhea, which was subsided after interruption of administration. These results suggested that Ketotifen was effective in treatment of allergic rhinitis.

The Foster Kennedy syndrome is ipsilateral optic disc atrophy and contralateral optic disc edema that is caused not only frontal lobe tumor but also another intracranial tumors and non tumorous conditions. In this case, suspected neurofibromatosis by the skin and ocular manifestations, there are glioblastoma multiforme in left temporoparietal lobe and undefined mass with bony destruction of the ipsilateral sphenoidal wing ridge. Authors asserted that ipsilateral optic atrophy was caused by direct compression of the undefined mass on sphenoidal wing ridge to the optic nerve and the contralateral disc edema was result from high intracranial pressure caused by glioblastoma multiforme.
