OBJECTIVETo investigate the presence of HPV infection of oral mucosa proliferative lesions in children and determine the associations of HPV types with oral mucosa lesions in children.

METHODSImmunohistochemical method and in situ hybridization techniques were applied to detect human papillomavirus (HPV) infection in biopsies taken from clinical lesions in oral mucosa of 30 children.

RESULTSThe most frequent lesions detected were SCP (66.7%), followed by CA and FEH. The HPV viral antigen was present in 73.3% (22/30) of the oral benign epithelial proliferative lesions in children. A high frequency HPV was found in CA (6/6) and SCP (15/20) by means of IHC. In the ISH positive case, high risk HPV 16/18 was observed in 77.3% (17/22).

CONCLUSIONThis study demonstrates a high prevalence of HPV infection in children's oral mucosa proliferative lesions, and high-risk HPV16/18 are predominant in children's oral mucosa proliferative lesions.

OBJECTIVETo detected HPV human papillomavirus DNA and HPV types in NIP nasal inverted papilloma, to inquire into the infection of HPV in the pathogenesis of NIP, and the relationship of HPV with the prognosis of NIP.

METHODSTwenty-eight cases of NIP were divided into 3 groups: no recurrence group (group 1), recurrence group (group 2), squamous cell carcinoma (SCC) arising in NIP group (malignancy group, group 3). Ten cases of benign nasal polyps were used as control group. HPV-DNA types of 6, 11, 16, 18 and general type were detected by polymerase chain reaction (PCR).

RESULTSTotal positive rate of HPV in NIP was 75% (21/28). The positive rate of group 1 was 42% (5/12), all with single and low risk HPV type infection (4 with HPV6 and 1 with HPV11). Thirteen cases of recurrence and 3 cases of malignancy were discovered to have HPV-DNA, in group 2, the majority were HPV6 and HPV11, 4 cases with double infection;in group 3, the majority were HPV16 and HPV18, and 2 cases with double infection.

CONCLUSIONSThe occurrence of NIP was related with HPV infection. To detected HPV and its subtypes can show the cases easily to have recurrence or malignant change. For the cases with HPV positive, double infection and infected with high risk types should be closely followed-up.

OBJECTIVE: To investigate the correlation of laryngeal squamous cell carcinoma (LSCC) and precancerous lesion with HPV infection subtypes and possible clinical relationship. METHOD: Eighty-three cases in paraffin embedded tissues were detected with thirty seven HPV subtypes by flow-through hybridization and gene chip (HybriMax), including 31 cases of laryngeal squamous cell carcinoma, 52 cases of precancerous lesions (29 cases of vocal cord leukoplakia and 23 cases of laryngeal papilloma), and 36 cases of vocal cord polyp as normal vocal mucosa were used as control. RESULT: The total positive rate of HPV was 19.4% in the group of laryngeal squamous cell carcinoma (6/31), 0 in vocal cord leukoplakia, 65.2% in laryngeal papilloma (15/23), and the control group were all negative, HPV virus subtype of HPV-positive laryngeal squamous cell carcinoma were all high-risk HPV16; and there were 6 HPV virus subtypes in laryngeal papilloma (8: HPV6,4: HPV52, 1: HPV11, 1: HPV18, 2: HPV45, 3: HPV16), individual mixing two or more subtypes infection. HPV infection of laryngeal squamous cell carcinoma and precancerous lesions has no statistically significant difference according to gender, high low-risk subtypes. CONCLUSION HPV infection related to laryngeal squamous cell carcinoma and precancerous lesions, but no significant correlation with the subtype distribution of high and low risk; HPV detection is making positive sense to clinical diagnosis of laryngeal carcinoma and precancerous lesions as well as the development of specific HPV subtype vaccine.

We reported a case of an African American woman who went to the hospital with palpable right breast lump with bloody nipple discharge at University of Texas Medical Branch at Galveston. The modalities of breast imagings included mammography and ultrasonography. The method used for viral identification was Linear Array HPV genotyping test. Intraductal papilloma revealed as high density tubular or rounded lobular masses with partially circumscribed, obscured margins and clustered punctate microcalcifications on mammograms. Ultrasound showed as intraductal masses with dilated ducts. The core biopsy demonstrated duct filled with papillary lesion and post excision revealed intraductal papilloma. HPV DNA types 16, 33, 58 and 71 were detected after use of Linear Array HPV genotyping test.

OBJECTIVE: To investigate the relationship between human papillomavirus (HPV) infection and pathogenesis of nasal inverted papilloma (NIP) and its malignant transformation. METHOD: Fifty-seven cases of NIP were divided into 2 groups: benign group, squamous cell carcinoma (SCC) arising in NIP group (malignancy group). HPV-DNA types of 6, 11, 16, 18 were detected by polymerase chain reaction (PCR) in 57 cases of NIP. Thirty cases of nasal polyps were control. RESULT: Total positive rate of HPV in NIP was 64.9% (37/57). The positive rate of benign group was 60% (27/45), all with single and low risk HPV11 type infection. The positive rate of malignancy group were was 83.3% (10/12), and the majority were HPV16 and HPV18. Five cases had double infection (4 with HPV16 and HPV 18, 1 with HPV11 and HPV18), four had single HPV16 infection, another one had single HPV11 infection. However, HPV-DNA was not detected in any cases of nasal polyps. CONCLUSION Infection of HPV-DNA has an important effect in pathogenesis of NIP. Meanwhile, there maybe a close relationship between high risk HPV16 type and HPV18 type and malignant transformation of NIP.

OBJECTIVE: To investigate the Human papilloma viral types 6 and 11 in a large pediatric population in XinJiang and the different expression in chinese and uyghur pediatric population. METHOD: Using polymerase chain reaction (PCR), we analyzed paraffin embedded tissue in 42 cases of juvenile Recurrent Respiratory Papillomatosis (JRRP)and determined the HPV types 6 and 11, and to correlate these results with retrospectively analysis about those cases who were consecutively treated in our ENT department, meanwhile we carry out a critical review of the literature of JRRP. RESULT: A total HPV infection positive rate was 97.61% (41/42), and HPV11 positive rate was 63.41% (41/26), HPV6 positive rate was 36.58% (41/15). In uyghur patient HPV11 positive rate was 65.38% (17/26), HPV6 positive rate was53. 33% (8/15). in Chince patient HPV11 positive rate was 34.61% (9/26), HPV6 positive rate was 46.67% (7/15). CONCLUSION Juvenile laryngeal papilloma is associated with HPV11, HPV6 infection and we considered that HPV11 infection may be the important guideline of the evaluation of disease prognosis. but no statistical signtificance was determined in the patients of various ethnic groups in Xin jiang (P > 0.05).

OBJECTIVE: To investigate the significance of expression of COX-2, p21, Ki67 and HPV in nasal inverted papilloma. METHOD: Detecting COX-2, p21, Ki-67 in 30 cases of nasal inverted papilloma (NIP), 20 cases of nasal polyps (NP) and 10 cases of normal nasal mucosa (NM) by two step immunohistochemical method, and HPV virus by flow-through hybridization method. RESULT: The positive expression rate of COX-2 and Ki-67 in NIP, NP and NM group was decreased in turn, COX-2 had significant difference in the groups(χ2 = 30.00, P< 0. 05); the positive expression rate of Ki-67 had significant differences between NIP and NM group (χ2 = 8. 533, P<0. 05). The expression of COX-2 in NIP tissues was positively correlate with that of Ki-67 by using Spearman rank correlation analysis (r=0.78, P<0.05). Expression of p21 were not observed in NIP group. The positive rate of HPV was 26. 67% in 30 cases of NIP, all of HPV16 type. CONCLUSION COX-2, Ki-67 and HPV infection have certain correlation with the occurrence of NIP. The occurrence of NIP has relationship with inflammatory reaction mediated by COX-2. Ki-67 can well reflect the proliferation activity of tumor cells, and can be used to measure the proliferation rate of nasal inverted papilloma. The COX-2 and Ki-67 have a synergistic role in the pathogenesis of NIP. p21 has no significant relationship with the incidence of NIP. HPV infection is related to the pathogenesis of NIP, but not as a;major factor in the pathogenesis of NIP.

OBJECTIVE: To investigate the efficacy of submucosal resection by CO2 laser in the treatment of recurrent laryngeal papilloma and the effect on prognosis. METHOD: A total of 11 patients diagnosed as recurrent laryngeal papilloma were included in this review. Papilloma was marked before operation and checked under fibro-laryngoscope. Papilloma was resected completely including the submucosal tissure with CO2 laser or microequipment. In widespread papilloma, false membrane in raw surface were cleared 7-10 days after operation. Surgical specimens (including membrane) were detected by routine pathology, HPV typing and immunohistochemical pathologic examination. The patients were checked once a month in the first 3 months after operation, and then once for every 3 months. Once the hoarseness and other symptoms aggravated or the disease was recurrent, the patients were treated immediately. RESULT: HPV viral DNA was found in 10/11 cases, with HPV11 (7/11 cases) and HPV6 (3/11 cases). Cases with regards to follow-up, from 6 months to 1 year, 3 cases were followed up 1 year after operation, without recurrence. Five patients including 2 children were followed up 6 to 12 months after operation, without recurrence. Two children underwent 2 or 3 operations, were followed-up more than 6 months withouting recurrence. CONCLUSION Papilloma submucosal resection could decrease postoperative recurrence and is worth to be further investigated.
