National Journal of Andrology 2015;21(11):1001-1004
OBJECTIVETo explore the genotypes of human papilloma virus (HPV) in male patients with condyloma acuminate in Lishui area of Zhejiang Province, China.
METHODSUsing HybriMax, we identified the genotypes of HPV of the verruca samples from 110 male condyloma acuminate patients aged 16 - 65 years in Lishui area.
RESULTSHPV infection was detected in 107 (97.27%) of the condyloma acuminate patients, including 76 cases (71.02%) of simple infection and 31 cases (28.97%) of multiple infection. The peak age of infection was 21 - 40 years old. Totally, 14 genotypes of HPV were identified, including the high-risk genotypes as HPV16, 53, 52, 33, CP8304, 58, 51, 45, 66, 68, and 59, which accounted for 44.85% of the cases, and the low-risk ones as HPV6, 11, and 19 (43), with an infection rate of 93.45%.
CONCLUSIONThe low-risk genotype is a dominant type of HPV infection and the rates of high-risk genotype and multiple infection are high among the male condyloma acuminate patients in Lishui area.

OBJECTIVETo identify and assess multiple human papillomavirus types in condyloma acuminatum lesions from patients with genital warts in Beijing area, and compare different features between otherwise healthy and immunosuppressed patients.
METHODSPCR, RFLP and nucleotide sequencing analysis were used to determine HPV types from individual lesions.
RESULTSThe predominant type from other healthy patients was HPV6, secondly HPV11. The mean age of patients infected by HPV6 was lower than that of HPV11 and HPV6 + 11. While lesions from immunosuppressed patients were often contained HPV11 or mixed with HPV6. Besides, HPV types 16 and 53 were detected from infected lesions than other HPV types.
CONCLUSIONSHPV6 was the major pathogen of condyloma acuminatum, but infected patients were at lower ages. While HPV11 was most often detected from immunosuppressed patients. As a low risk virus in normal genital tract, HPV53 also could be a pathogen in genital warts.

Objective:
To investigate the distribution of the gene subtypes of human papillomavirus (HPV) in male patients with condyloma acuminatum (CA) and analyze the characteristics of the gene subtypes.
METHODS:
We extracted genomic DNA of the HPV virus from the genital tissue of 70 male CA patients, detected the DNA subtypes of HPV using the PCR-reverse dot hybridization technique, and analyzed the rates of different subtypes identified and their characteristics of distribution in different age groups.
RESULTS:
The male HPV-positive patients were mainly infected at the age of 20-39 years, primarily with high- and low-risk mixed infection of various subtypes, which accounted for 61.54% in the 20- to 29-year-olds and 42.86% in the 30- to 39-year-olds. Among the 70 CA patients, 22 HPV subtypes were identified, the top five subtypes including HPV 11 (21.08%), HPV 6 (19.46%), HPV 42 (6.49%), HPV 59 (6.49%) and HPV 53 (5.95%); 20 infected with a single subtype (28.57%), 19 with two subtypes (27.14%) and 31 with three or more (44.29%); and 30 infected with a low-risk single subtype (42.86%) and 40 with both high- and low-risk multiple subtypes (57.14%).
CONCLUSIONS
Male patients with CA are mainly infected with HPV 11 and HPV 6, with a significantly higher rate of multi-subtype than single-subtype infection, and the multi-subtype patients chiefly with high- and low-risk mixed infection. Men aged 20-39 years old are most commonly affected by CA.

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 evaluate the effectiveness of sleeve circumcision of prepuce and coronary sulcus skin in the treatment of patients with multiple condyloma acuminatum (CA) of coronary sulcus of penis.
METHODSIn a randomized clinical control study, 35 patients were randomized to the treatment group and received sleeve circumcision of prepuce and coronary sulcus skin. 34 patients were randomized to the control group, received electric cauterization of verrucae plus the general circumcision. The recurrence of CA was evaluated in follow-up visit within three months after the treatment.
RESULTSThe stitches were taken out 10.2 days after operation in the treatment group, and 8.1 days in the control group. There were no complication in the treatment group, the average healing time of electric cauterization wound was 19.4 days in the control group. There was a statistically significant difference in the recurrence rate of CA between the treatment group and the control group (5.7% vs 26.5% , P <0.05).
CONCLUSIONSThe sleeve circumcision of prepuce and coronary sulcus skin is more effective than electric cauterization of verrucae plus the general circumcision in the treatment of patients with multiple condyloma acuminatum of coronary sulcus of penis.

OBJECTIVETo determine the correlation between DNA load of human papillomavirus (HPV) and recurrence of condyloma acuminata (CA).
METHODSThe HPV6/11 and HPV16/18 DNA load of 31 cases of primary CA and 32 cases of recurrent CA were detected by real-time fluorogenic quantitative PCR.
RESULTSAmong the 63 CA patients, 62 cases were HPV6/11 DNA positive. The positive rate was 98.4%. The ranges of HPV6/11 DNA load in primary and recurrent CA were 1.4x10(3)-6.7x10(7) copies/ml and 1.2x10(4)-3.6x10(8) copies/ml respectively. Of 62 cases with HPV6/11 DNA positive, 7 cases were HPV16/18 DNA positive (11.3%). The ranges of HPV16/18 DNA load in primary and recurrent CA were 1.9x10(3)-1.6x10(4) copies/ml and 1.4x10(5)-1.7x10(7) copies/ml respectively. The HPV6/11 and HPV16/18 DNA load in recurrent CA were higher than in primary CA (P < 0.05). The DNA load of HPV6/11 was positively correlated with times of recurrence and course of disease (r=0.37 and 0.30 respectively).
CONCLUSIONCertain correlation exists between DNA load of HPV and recurrence of CA.

OBJECTIVEHuman papillomavirus (HPV) commonly exists in healthy individuals, but its prevalence in the pubic hair follicles is not yet clear, nor is the relationship between HPV infection in the pubic hair follicles and the recurrence of genital warts in men. This study aimed to investigate HPV infection in the pubic hair follicles of healthy men and patients with genital warts, and to look into the correlation of HPV infection with recurrent genital warts.
METHODSWe included in this study 122 healthy men aged 21-80 years and 86 male patients with genital warts aged 24-61 years, detected HPV in their pubic hair follicles by PCR, and made comparative analysis of the data obtained from the two groups.
RESULTSThe positive rate of HPV in the pubic hair follicles of the healthy males was 17.21% (21/122), including 15 cases of HPV6, 4 HPV11, 1 non-HPV6/11 and 1 the mixed type (both HPV6 and HPV11), while that of the genital wart patients was 32.55% (28/86), including 17 cases of HPV6, 7 HPV11, 2 non-HPV6/11 and 2 the mixed type.
CONCLUSIONThe incidence of HPV infection is higher in patients with genital warts than in healthy men, while the types of HPV involved are basically the same in the two groups, mainly HPV6 and HPV11.

The telomerase activity in condyloma acuminatum (CA) tissue with human papillomavirus (HPV) types of 6/11 and 16/18 was detected to investigate the function of telomerase in the occurrence, development and carcinogenesis of genital CA. Forty-two biopsies from patients with genital CA and 30 control tissue samples were tested for telomerase activity, HPV presence and types. The telomerase activity was determined by modified telomerase repeat amplification protocol (TRAP) assay and HPV typing by polymerase chain reaction (PCR) with typing-specific primers. Results showed that HPV-DNA was negative and the expression rate of telomerase was 16.7% in all normal skin samples. All CA samples were positive for HPV (6/11 type was found in 32 cases, 16/18 in 3 and mixed type in 7). Telomerase activity was detectable in all CA patients. The telomerase activity in CA of 16/18 type was apparently higher than in CA of 6/11 type. It was concluded that the hyperplasia in CA might be increased as a result of HPV infection, suggesting that the activation of telomerase by HPV, especially by 16/18 type may play a role in the etiology and carcinogenesis of genital CA.

OBJECTIVETo clarify the role of midkine (MK) in vulvar carcinogenesis though examination of its expression in vulvar lesions including vulvar condyloma acuminata (VCA), vulvar intraepithelial neoplasia (VIN) and vulvar squamous cell carcinomas (VSCC), and to analyze the relationship between MK expression and human papilloma virus (HPV) infection.
METHODSThirty VSCC, 15 VIN and 10 VCA patients were studied by streptavidin-biotin-immunoperoxidase method. MK expression was compared with clinicopathologic features of vulvar tumors.
RESULTSMK was expressed in 26 of 30 VSCC (87%), 3 of 5 VIN III and all VCA samples, whereas no MK expression was detected in the VIN I-II samples or in normal epithelium. The difference of MK expression between VIN III and VSCC was statistically significant (P < 0.05). MK was more intensely expressed in differentiated-type (well differentiated and moderately differentiated) VSCC than in undifferentiated-type (poorly differentiated) VSCC. There was no statistically significant correlation between MK expression and clinical stage, lymph node metastasis and HPV infection in VSCC. MK expression were observed in all HPV-positive specimens including 2 VSCC, 1 VIN III and all VCA.
CONCLUSIONSMK gene expression may be a late event in vulvar squamous cell malignant transformation, and may be associated with vulvar tumor cell differentiation. HPV-positive vulvar tumors expressed MK protein.

OBJECTIVETo investigate the use of a 32P application device (AD) in the treatment of condyloma acuminatum (CA) in the rectum, and to compare its clinical effect with that of the microwave therapy.
METHODSThis study included 107 cases of CA in the rectum, 99 males and 8 females, aged 21-58 (33.6 +/- 9.4) years. Forty-six of the patients (the AD group) were treated with a self-made 32P application device, which, as a tube-shaped carrier of radionuclide 32P colloid, was fixed in the rectum at the diseased part for medication at 4.9-8.2 Gy for 3-5 hours once and 1-2 times a week. The other 61 (the microwave group) were treated by microwave burning under local anesthesia. Both groups of patients were followed up for over 3 months for comparison of the therapeutic results and observation of the stability and reliability of the 32P application device.
RESULTSThe rates of cure, reoccurrence and adverse reaction were 84, 8%, 13.0% and 8.7% in the AD group, compared with 40.3%, 55.7% and 75.4% in the microwave group, with statistically significant differences between the two groups (P < 0.01).
CONCLUSIONThe 32P application device, with its advantages of low cost, easy operation, good effect, high safety and reliability, low recurrence, fewer adverse events and good acceptability, is highly valuable for the treatment of CA in the rectum.
