Objective: To assess the prevalence and related factors of HIV infection among male clients of the female sex workers in Hekou Yao autonomous county of Honghe Hani Yi autonomous prefecture (Hekou county) in Yunnan province in China, 2014-2015. Methods: Serial cross-sectional survey was conducted during June 2014 to November 2015. Convenience sampling methods were used to recruit the male clients for this study. Self-reported information on social-demographic characteristics, with sexual and drug behavior patterns, was gathered. Both blood and urine samples were collected for HIV, with for opiate testing. Multivariate logistic regression and Exhaustive CHAID method were used to determine the correlated factors associated with HIV infection. Statistical analysis was used by SPSS 22.0 software and Clementine 12.0 software. Results: The overall HIV prevalence of male clients was 2.06% (16/776). Male clients who keep using condom with female sex worker was estimated as 68.81% (534/776). The last commercial sexual partner of Vietnamese male clients was all Vietnamese female sex workers. Compared with Chinese male clients, Vietnamese male clients have a higher rate of morphine positive. Factors as: age ≥50 years vs. age <30 years (OR=8.11, 95%CI: 1.26-52.16) and testing for morphine positive vs. morphine negative (OR=7.35, 95%CI: 1.42-38.06) were significantly associated with HIV infection through multiple logistic regression analysis. Through Exhaustive CHAID, it confirmed that age was the primary factor that associated with HIV infection of male clients. Conclusions Relationship between morphine and HIV infection indicated that HIV prevalence of male clients in Hekou county was influenced by the combined effect of both illegal drug use and commercial sexual behavior. Special attention should be paid to male clients over 50 years of age, on HIV intervention.

OBJECTIVETo investigate the effective method for correction of nasal deformity after unilateral cleft lip.

METHODS50 cases with secondary nasal deformity after unilateral cleft lip were retrospectively analyzed. All the patients underwent nasal and lip muscle reposition operation to restore the symmetry of nasal alar.

RESULTSThe nasal deformity was greatly improved in all the 50 cases. The malposition of nasal column and nasal alar was corrected. The symmetry was markedly improved. The measurement before and after operation showed significant difference ( P<0.05).

CONCLUSIONSThe reasons of secondary nasal deformity after unilateral cleft lip are complicated. The muscle reposition operation can effectively improve the deformity.

OBJECTIVETo investigate infections of syphilis, neisseria gonorrhoeae, chlamydia trachomatis and the related risk factors in men who have sex with men (MSM) in Jiangsu province.

METHODSA total of 400 MSM were enrolled by Snowball Sampling Method from August to October in 2010 and then 328 cases were surveyed by a questionnaire and collected serum sample 5 ml per person as well as rectal swab on the spot; all of the serum samples were tested for syphilis by ELISA and TRUST, and all of the rectal swabs were tested for neisseria gonorrhoeae or chlamydia trachomatis. The influencing factors of syphilis, neisseria gonorrhoeae, chlamydia trachomatis were analyzed by logistic regression analysis.

RESULTSThe 328 MSM were (32.46 ± 9.72) years old, 59.15% (194/328) were unmarried.75.00% (246/328) MSM had rectal sex with men in the past 3 months, and condom use rate for recent sex was 56.71% (186/328), while 53.05% (174/328) MSM didn't have sex with women in the last 3 months. The syphilis infection rate among MSM was 13.41% (44/328), the neisseria gonorrhoeae infection rate was 3.66% (12/328), and the chlamydia trachomatis rate was 11.59% (38/328). The number of sex partners was the key factor that influenced syphilis infections (OR = 4.213, 95%CI: 1.133 - 15.656).

CONCLUSIONThe prevalence of syphilis and chlamydia trachomatis was high in MSM in Jiangsu, while risk behavior rate were high in the MSM and then should be intervened.

BACKGROUNDThe columella, nasal tip, lip relationship in the bilateral cleft lip nasal deformity remains a great challenge for plastic surgeon. An esthetically satisfying result is difficult to obtain. A subset of patients with bilateral cleft lip nasal deformity still require columellar lengthening and nasal correction and philtrial construction. This study aimed to provide a new method based on the forked flap to improve the final appearance of these patients.

METHODSA technique to correct this deformity is described. This consists of (1) a newly modified forked flap including the orbicularis oris muscle and nasalis muscle along the whole flap for columellar lengthening, (2) a reverse V shaped flap from the lower portion of the columella and the prolabium for normal size phitrum construction, (3) inserting the vermilion portion of the forked flap and advancing the nasal floor medially and anteriorly to lengthen and maintain the nasal septum side of the columella for proper tip positioning, (4) open rhinoplasty, allowing definitive repositioning of the lower lateral cartilages, (5) reconstruction of the orbicularis orismuscle as required, and (6) the flaring nostril floor advancing medially and constructing the sill.

RESULTSThis technique was applied to 15 cases of secondary bilateral cleft lip nasal deformity. All the flaps took without signs of partial necrosis. In all cases, the nasal tip was projected forward with adequate columella elongation, and the height of the prolabium was added with normal size philtrial dimensions.

CONCLUSIONSThis method makes maximum use of the tissue containing the scar in the lip and limits tissues in the lower portion of the columella and the prolabium for adequate columella elongation and reconstruction with normal size philtrial dimensions. It is a very reasonable and useful method in correction of secondary bilateral cleft lip nasal deformities.

OBJECTIVETo investigate the functional repair of secondary deformity of unilateral cleft lip.

METHODSThe nasal branch, nasolabial branch, and labial branch of orbicularis oris muscle were dissected and repositioned precisely to correct the secondary deformity of unilateral cleft lip.

RESULTS96 patients were treated successfully with this method during Jan. 2005 to Oct. 2008. Good cosmetic and functional results were achieved. 85 cases were followed up for 3 months to 5 years with a satisfactory rate of 94.1% (80/85 cases).

CONCLUSIONSThe application of refined anatomy and precise reposition in orbicularis oris muscle is important to ensure therapeutic effect in patients with secondary deformity of unilateral cleft lip.

OBJECTIVETo develop a new method for reparation of cleft lip, and to evoke more colleagues for advance practices and study, in order to determine her indication and contraindication as soon as possible.

METHODS48 cases were included into this study. Trilobate flap were designed in floor of nose and lip area in cleft side, rotate two of the three flaps upwards, respectively to elevate the tip of nose, and to reconstruct the floor of nose. As for the left flap, it was derived transversally to opposing side, sutured with the flap of non-cleft-side.

RESULTSWith this technique, less tissue was lost, better vertical lengthening and good formed cuspids-bow was achieved, and the scar was a parallel line being symmetry to the philtrum column opposite. Meanwhile, because the tension was mainly located in the area where there was no mini flaps, the blood supply was good enough, rarely occur any necrosis in the tip of flaps. All cases in this study obtained perfect healing, with good appearance at nostrils and floor of nose.

CONCLUSIONSIn use of the method of trilobate flap, we can draw down the peak of the cuspids bow effectually, hence avoid the addition cut in the lower part of the lip, decrease the scar on skin, as well as nice reconstruction of floor of nose, philtrum column and nostril. Because lack of long term study, we evoke more colleagues for cooperation in advance study.

OBJECTIVETo investigate the reconstruction of wide vermilion and orbicularis oris muscle defect with satisfactory outcome of aesthetics, sensation, and function.

METHODSThe buccal musculomucosal flap based on the anterior buccal branches of the facial artery was used to reconstruct wide defect of vermilion and orbicularis oris muscle on upper or lower lip.

RESULTS7 patients were treated. 5 cases had no postoperative complication. Partial mucosal necrosis on the tip of the flaps happened in 2 cases, but the underlying muscle survived and was re-mucosalized spontaneously. No other complication was observed. The sensation of cold, heat and touch could be detected on the first postoperative day. Electromyographic and electron microscopic studies confirmed innervation of the muscle in the flap.

CONCLUSIONSThe buccal musculomucosal flap is a reliable reconstruction option for wide defect of vermilion and orbicularis oris muscle which can' t be reconstructed with conventional method. Satisfactory aesthetic and functional results can be achieved with the buccal musculomucosal flap.

OBJECTIVETo explore a method to repair larger cleft palate and lengthen soft palate without oral palate raw surface and scar formation, reduce the effect on maxilla and dental arch development.

METHODSA modified double opposing Z-plasty was used to lengthen soft palate and the nasal palate was closed by using large turn-over mucoperiosteal flaps on the oral surface of the junction of the hard palate and soft palate, oral raw surface on the palate was closed by a buccal myomucosal island flap.

RESULTSThirty-six palates have been repaired by this procedure, all of which had satisfactory results without flap necrosis, infection, difficulties in opening mouth and facial nerve injury except two post-operative fistulas. Eight patients were followed up and all display complete velopharyngeal closure.

CONCLUSIONSUsing unilateral buccinator myomucosal island flap with double opposing Z-plasty to repair wider palatal cleft can get a satisfactory soft palate lengthening. At the same time it can avoid bone surface exposing and scar formation; it is a safe and reliable procedure.

OBJECTIVETo assess the feasibility and actuality of MR imaging on diagnosis and evaluation of velopharyngeal insufficiency preoperatively.

METHODSSince 2002, six patients with velopharyngeal insufficiency were examined with MRI using midsagittal, coronal, and axial images, contrast with radiography, to affirm configuration and movements of soft palate, posterior and lateral pharyngeal walls, and velopharyngeal opening for the choices of following surgeries.

RESULTSMRI visualizes directly and measures objectively the shorter soft palate, confined movements of soft palate, lateral or/and posterior pharyngeal wall, and deeper and enlarged velopharyngeal opening, which were coincided with clinical symptoms and affirmed by observations in the following operations, surpassing radiography.

CONCLUSIONSMRI is effective, actual, and uninvasive in imaging and measuring the velopharyngeal insufficiency, thus has a potential role in investigation and planning surgical repairs.
