19 years old female had untreated Veau classification class II cleft palate with ectopic eruption of upper right lateral incisor and congenital missing of lower lateral incisors. Upper left lateral incisor, left first molar aid lower left first molar were root restswithperiapicalpathologiclesions. So all root rests were extracted and prosthodontic rehabilitation after orthodontic treatment was planned. She was treated by means of multibanded system with face bow. After 23 months all orthodontic correction were achieved and, as soos as debanding procedure was done she was referred to oral surgeon and prosthodontist for surgical operation and bridge construction.

BACKGROUND: Malassezia species (spp.) are cutaneous opportunistic pathogens and associated with various dermatological diseases including seborrheic dermatitis, dandruff and atopic dermatitis. Almost all Malassezia spp. are obligatorily lipid-dependent, which might be caused by lack of the myristic acid synthesis. Recent genome analysis of M. restricta and M. globosa suggested that the absence of a gene encoding fatty acid synthesis might be compensated by abundant genes encoding hydrolases, which produce fatty acids, and that lipases and phospholipases may play a role in virulence of the fungus. OBJECTIVE: The current study aimed to investigate the contribution of lipases and phospholipases in virulence of the M. restricta as being the most frequently isolated Malassezia spp. from the human skin. METHODS: Swap samples of two different body sites of at least 18 patients with seborrheic dermatitis were obtained and in vivo expression of lipases and phospholipases of M. restricta was analyzed by the gene specific two-step nested RT-PCR. RESULTS: The results of the current study suggest that majority of the patients display expression of lipase RES_0242. CONCLUSION: These data imply a possible role of lipase in the host environment to produce free fatty acids for the fungus.

Thanatophoric dysplasia (TD) is a sporadic lethal type of skeletal dysplasia featuring micromelia, decreased thoracic dimension and macrocephaly. To date, several kinds of mutation in fibroblast growth factor receptor 3 (FGFR3) has been identified in TD. We experienced a case of TD type I and underwent sequencing of the exon 7, 10 and the stop codon of FGFR3 to identify the type of mutation. TDI was diagnosed by the prenatal ultrasound at 25 weeks of gestation. The pregnancy was terminated and the diagnosis was confirmed by radiological and histologic examinations. The genomic DNA was extracted and the sequences of the exon 7, 10 and the stop codon of FGFR3 were amplified by PCR. The sequencing was performed for the each PCR products by dideoxyterminator method. The nucleotide transition from G to T was found in the nucleotide 1108, which is a part of the transmembrane domain, exon 10. To date, only one type of mutation (nucleotide 742) in the FGFR3 was identified in TD1 among Asian. This case firstly reveals the mutation of FGFR3 other than mutation at nucleotide 742 in TD1.

Background:
The lipophilic yeasts Malassezia spp. are normally resident on the surface of the human body, and often associated with various skin diseases. Of the 18 known Malassezia spp., Malassezia restricta is the most predominantly identified Malassezia sp. found on the human skin. Malassezia possesses a large number of genes encoding lipases to degrade human sebum triglycerides into fatty acids, which are required not only for their growth, but also trigger skin diseases. Previously, we have shown that MrLIP5 (MRET_0930), one of the 12 lipase genes in the genome of M. restricta, and is the most frequently expressed lipase gene in the scalp of patients with dandruff.
Objective:
In this study, we aimed to analyze the activity, stability, and expression of MrLip5, with particular focus on pH.
Methods:
We heterologously expressed MrLip5 in Escherichia coli, and purified and analyzed its activity and expression under different pH conditions.
Results:
We found that MrLip5 was most active and stable and highly expressed under alkaline conditions, which is similar to that of the diseased skin surface.
Conclusion
Our results suggest that the activity and expression of MrLip5 are pH-dependent, and that this lipase may play an essential role at the M. restricta-host interface during disease progression.

CD44 is a cell-surface glycoprotein postulated to play a role in tumor cell metastasis. Aberrant expression of the cell adhesion molecule CD44 has been detected in human tumors and the expression of specific isoforms(splice variants) has been shown to be associated with metastasis and poor prognosis in human malignancies. We used variant exon sequence-specific monoclonal antibody to epitope encoded by exon v6 of human variant CD44 to study the expression of CD44 splice variant by immunochemistry in fifty nine samples of human cervical cancer. twenty seven tissue samples of cervical intraepithelial neoplasia(CIN) and normal cervix were included in this study. CD44v6 was stained positive in the basal and parabasal layer of normal epithelial cells homogenously but was absent in the stromal cells. The intensity of CD44v6 staining was the strongest in invasive squamous cell carcinoma followed by normal cervical epithelium, CIN, adenocarcinoma. In the malignant samples, heterogeneity in staining intensity among different clusters of tumor cells was observed. Furthermore the intensity of staining was stronger in proportion to stage, depth of invasion, lymphovascular invasion(p<0.05), and lymph node metastasis(p=NS). This study suggest that the expression of CD44v6 adhesion molecule may be useful value in predict the high stage, depth of invasion, lymphovascular invasion and lymph node metastasis probably.
