ABSTRACT

Objective@#To understand the vaccination of varicella attenuated live vaccine (VarV) among students in collective institutions, to provide a basis for analying the protective effect of vaccination.@*Methods@#All collective institutions with chickenpox epidemic and post exposure vaccination in Jing an District from 2017 to 2019 were investigated. All students( n =6 473) in the affected class were included. Vaccination status and the incidence information of disease were collected to analyze vaccine effectiveness (VE).@*Results@#The proportion of study subjects without an immunization history decreased year by year, and 7.5% in 2017, 7.2 % in 2018, and 4.9% in 2019. The proportion with a history of one dose prior to exposure in cases was 90.0%, it was lower than 93.5% in the non cases ( χ 2=6.53, P <0.05). The proportion with one dose as post exposure prophylaxis in cases was 8.3%, it was much lower than 44.1% in the non cases ( χ 2=179.06, P <0.01). The proportion with one dose as post exposure prophylaxis in secondary cases was 28.6%, much lower than 44.1% in the non cases ( χ 2=9.44, P <0.01).Unvaccinated ones and the second dose as post exposure prophylaxis ones in cases had the highest rate of varicella development (11.0%), a history of one dose prior to exposure and one dose as post exposure prophylaxis in cases had the lowest varicella rate (1.0%).There was a clear protective effect within two years after one dose of VarV inoculation, VE was 63.1%(95% CI =11.0%-84.7%).@*Conclusion@#The vaccine effectiveness of one dose VarV was limited. Post exposure prophylaxis as early as possible was highly effective in decreasing secondary attack rate.

ABSTRACT

Urethrocutaneous fistula is a common complication of hypospadias. Repeated surgical repair of hypospadias often leads to the lack of penis skin and insufficient coverage of surrounding tissues, resulting in the formation of intractable urethrocutaneous fistula. The clinical data of a patient with penile segment urethral skin fistula who failed to repair repeatedly were retrospectively. This patient was treated with artificial webbed penis. After 6 months of follow-up, the patient had no recurrence of fistula, urination was unobstructed, and the appearance of penis was satisfactory.

ABSTRACT

Objective@#To evaluate the effect of vascular localization using computerized tomography angiography (CTA) combined with refined three dimensional (3D) printing in guiding the resection and reconstruction of complex oral cancer.@*Methods@#From December 2013 to July 2017, the clinical data of 30 patients with complex oral cancer enrolled in the Hunan Cancer Hospital were retrospectively analyzed. 15 patients received CTA+ 3D assisted surgery, while the other 15 patients underwent traditional surgery. In CTA+ 3D assisted surgery group, CT and Magnetic Resonance Imaging (MRI) data were combined with CTA to print refined solid 3D model and surgical guide plate. The preoperative and intraoperative virtual surgical system and the operative experience were combined for preoperative evaluation and surgery. In traditional surgery group, preoperative evaluation and surgery were performed according to imaging data and surgeons′ clinical experience. Operative time, intraoperative blood loss, hospital stay and local recurrence rate were compared between the two groups.@*Results@#In CTA+ 3D assisted surgery group, one patient gave up surgical treatment after intuitively watching the lesion through the 3D model, and the remaining 14 patients underwent surgery as planned. All the 15 patients in traditional surgery group received surgery. But the preoperative plans of three patients were temporarily and passively modified due to insufficient preoperative evaluation. The average intraoperative blood loss was(320.1±27.2)ml in CTA+ 3D assisted surgery group and(430.2±30.3)ml in traditional surgery group. Mean operation time was(440.3±19.2)min and(552.2±23.3)min, respectively. Mean hospitalization time was (20.4±3.2)d and (25.1±3.7)d, respectively. The differences were all statistically significant (all P<0.05). 1 year and 3 years local recurrence rates were 9.1% and 28.6% in CTA+ 3D assisted surgery group, as well as 14.3% and 50.4% in traditional surgery group with statistical significance (P<0.05).@*Conclusion@#For complex oral cancer patients with difficulty in opening the mouth or postoperative recurrence, CTA vascular localization combined with fine 3D printing technology has significant advantages in the surgical process, surgical effect and postoperative evaluation index compared with traditional method using imaging data and clinical experience.

ABSTRACT

Background and purpose:The pedicled pectoralis major myocutaneous lfap has been a common choice of tissue lfaps for head and neck reconstruction. Nowadays, with rapid advancement in microsurgery, free lfaps gradually replace the pedicled lfaps. However, not all patients are good candidates for reconstruction surgery using free tissue lfaps. Adjacent pedicled lfaps are safer and more reliable. This paper explores potential application of pedicled pectoralis major myocutaneous flap in reconstruction of complex surgical defects following resection of advanced head and neck malignancies through modification of their preparation and repair method.Methods:Flap design scheme and method of preparation were modiifed to improve the pectoralis major muscle lfap. Fifty-one patients with surgical defects from resection of head and neck malignancies received reconstruction surgery using modiifed pectoralis major muscle lfaps.Results:Modiifed pectoralis major muscle lfaps survived completely in 51 patients. The area of defect regained its shape and appearance after reconstruction surgery. The area of defect obtained excellent functional recovery. Postoperative functional injuries to the donor sites were minimized.Conclusion:Modiifcation in designing and preparing method of the pectoralis major muscle flap improved repair range and distance in reconstruction of complex surgical defect following resection of head and neck malignancies. It also reduced necrosis rate of skin lfaps. Postoperative donor and recipient sites regained their appearance and functions successfully. The pectoralis major muscle lfap is one of the important tissue lfaps used in reconstruction of surgical defect following resection of a head and neck malignancy.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the causes of the vascular crisis and necrosis of free flaps used for reconstruction of defects following head and neck cancer resection and the managements of these issues.</p><p><b>METHODS</b>A total of 850 cases with head and neck tumors who underwent free flap reconstruction from October 2010 to April 2014 were studied retrospectively. The risks for vascular crisis and necrosis were analyzed with one-factor analysis and multivariate analysis.</p><p><b>RESULTS</b>The total success rate of 95.1% (808/850) for the free flap reconstruction was obtained. Twelve flaps due to poor blood supply indicated during operation were replaced by other free flaps. Among 73 flaps with vascular crisis, 31 flaps were salvaged by surgical exploration and subcutaneous injection of low molecular heparin calcium. Obesity, smoking, preoperative radiotherapy and surgeon's experience, rather than age, hypertension and diabetes, were the risk factors of skin flap necrosis. Two-vein anastomosis had a higher success rate than one-vein anastomosis.</p><p><b>CONCLUSIONS</b>The necrosis rate of free flaps can be reduced by the choice of suitable flaps, subtly preparation of flaps, carefully vascular anastomosis, and prompt perioperative managements. The two-vein anastomosis is recommended. Diabetes, hypertension and elderly patients are not the contraindications for free flap reconstruction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To report the experience of use of modified pectoralis major myocutaneous (PMMC) flaps in reconstruction of head and neck postoperative defects.</p><p><b>METHODS</b>A total of 107 patients who underwent head and neck defect reconstruction using modified PMMC flaps after tumor rescetion between Jan 2008 and Dec 2013 were analyzed retrospectively.</p><p><b>RESULTS</b>The success rate of reconstruction with modified PMMC flaps was 94.4% (101/107). Five patients had partial flap necrosis and their wounds healed with dressing change. One patient (0.9%) had total flap necrosis, followed by the second reconstruction using contralateral PMMC flap.</p><p><b>CONCLUSIONS</b>The modified falcate PMMC flap can obtain optimum quantity of the skin in the chest and decreasing the closing tension of the donnor site in favor of wound healing. The pedicle without muscle will not only maintain the partial function of the pectoralis major, but also help to avoid pressing the vascular pedicle within the subclavian tunnel. The muscular element the pedicled muscles of the PMMC flap can increase the ability of the flap to resist infection, which can use for covering an exposed carotid artery and improving the neck fibrosis of irradiated patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the reconstruction approaches and indications in repairing of postoperative defect after resection of oral floor carcinoma.</p><p><b>METHODS</b>To review the clinical data of 106 patients with oral floor carcinoma treated by radical resection with simultaneous reconstruction in the Department of Head and Neck Surgery at our hospital from July 2003 to March 2013, and to evaluate the advantages and disadvantages of various repair methods.</p><p><b>RESULTS</b>The patients were followed up for 2 months to 10 years. Their 3-year survival rate was 63.6% (42/66) and 5-year survival rate was 57.7% (30/52). One case had sternocleidomastoid myocutaneous flap necrosis, and was successfully repaired with elective pectoralis major myocutaneous flap. Another one case showed partial strap muscle flap necrosis, and the wound was well healed after debridement and dressing changes. Three cases of free flap crisis because of poor blood supply were successfully cured by flap emergency exploration. The rest were well healed. The eating and language function of the patients could meet the general needs of life.</p><p><b>CONCLUSIONS</b>At the time of radical resection of oral floor carcinoma, an appropriate repair method should be selected according to many factors such as disease conditions, defect size, patients' physical constitution, etc. Generally, adjacent pedicle flap is not recommended. Prosthodontics membrane, free forearm flap, free anterolateral thigh flap, pectoralis major myocutaneous flap and free fibula flap can basically meet the need of repair of the postoperative defect after resection of oral floor carcinoma, therefore, are recommended.</p>

ABSTRACT

OBJECTIVE@#To review the clinical manifestations and management of nasal sinus mucoceles invaded the skull base and orbit.@*METHOD@#Medical records for 30 patients of paranasal sinus mucoceles invaded the skull base and orbit were reviewed retrospectively. CT and MRI were important tools for diagnosing nasal sinus mucocele. The patients received endoscopic surgery to remove mucocele, some of them were operated auxiliary incision. Steroid therapies were given after the operations and routine examination with endoscopy were carried out during follow-up.@*RESULT@#All cases were successfully performed surgery without complications after the surgeries, or the majority of symptoms. However, vision recovery was observed only in some patients. Recovery of vision depended on the timing of surgery and severity of initial visual loss. Delay treatment can seriously compromise the recovery of vision impairment. Moreover, the patients without light perception before surgery had poor visual recovery even when optic nerve decompressions were performed.@*CONCLUSION@#Endoscopic surgery has effect on nasal sinus mucocele with visual loss. Because visual recovery depends on prompt diagnosis and surgical intervention,a good understanding of the disease and prompt imaging studies are important.

ABSTRACT

Background and purpose:Nowadays, about therapy of laryngeal carcinoma, people are paying more and more widely attention to ifnding out how to improve quality of patients’ life besides radical surgery. For glottic laryngeal carcinoma which invading anterior commissure or bilateral vocal cord, we performed modiifed frontolateral partial laryngectomy or modiifed cricohyoidoepiglottopexy, and contrastive analyzed the therapeutic efifcacy of the two ways. Methods:Sixty cases patients of glottic laryngeal carcinoma who treated in Hunan Provincial Tumor Hospital during 2005 to 2010, which invaded the anterior commissure or bilateral vocal cord, were randomly attributed to two groups as A and B;30 patients of group A were underwent modiifed frontolateral partial laryngectomy and repaired with bilateral sternohyoid muscle lfap, 30 patients of group B were treated by modiifed cricohyoidoepiglottopexy. Follow-up time of each patient was 5 years postoperation and clinical data were retrospectively analyzed. Results:The 5-year survival rate was 86.7%in group A as well as 83.3%in group B, and there was no statistical difference between two groups (P=0.718). Pronunciation function:22 cases in group A and 21 cases in group B whose pronunciation function can be competent in the noisy environment, and can pronounce“a”and“i”vowel;8 cases in group A and 9 cases in group B can pronounce only a“ha”,“hi”sound, that couldn’t communicate with others in a noisy environment. There was no statistical difference in pronunciation function between the two groups (P=0.774). Incidence of deglutition disorder 4 weeks postoperation:group A was 0 (0/30), group B was 16.7%(5/30), and the difference between the two groups was statistically signiifcant (P=0.026);average time of extubation postoperation:group A was (10±2.3) d, group B was (20±4.6)d, and the difference between the two groups was statistically signiifcant (P=0.0000);recurrence rate of dyspnea after extubation:group A was 16.7%(5/30), group B was 0 (0/30), and there was statistically signiifcant difference between the two groups (P=0.026). Conclusion: For the glottic laryngeal carcinoma which invading anterior commissure or bilateral vocal cord, there was no statistical difference in 5-years survival rate and function of pronunciation between modified frontolateral partial laryngenctomy and modified cricohyoidoepiglottopexy postoperation. The former had less postoperative deglution disorder, earlier extubation time, and to some extent, alleviated the suffering of the patients, but part of these patients needed secondary surgery due to dyspnea which resulted by radioactive tissue adhesion after extubation. The latter had more serious deglution disorder postoperation, longer recovery time, and relatively longer time to extubating, showed no again dyspnea after extubation, and had more extensive adaptation disease. In a word, each way of operation has its advantage respectively.

ABSTRACT

Objective To evaluate the value of evoked potentials (EP) in diagnoses of minimal hepatic encephalopathy (MHE) for liver cirrhotic patients without overt hepatic encephalopathy (OHE). Methods A blind and self control study was conducted in 114 liver cirrhotic patients without OHE. All patients were tested for MHE by the number connection test-A(NCT-A), digit symbol test (DST), visual evoked potentials (VEP), brain-stem auditoru evoked potentials (BAEP), short latency somatosensory evoked potentials (SSEP), P300 auditory event-related potentials (P300ERP). MHE was identified when the NCT-A or/and DST was abnormal. The positive rate was compared among VEP, BAEP, SSEP and P300ERP for their reliability and validity in diagnosis of MHE. Results Of 114 patients, 60 patients were found with MHE (52. 6%), which was positively correlated with Child-Pugh classifications (r=0. 278, P = 0. 003). The positive rate was found 17.5% in VEP, 29.8% in BAEP, 38. 6% in SSEP and 57. 0% in P300ERP. There was no significant difference in diagnosis of MHE between P300ERP and NCT-A+DST (X2 =0. 432,P = 0. 511). The sensitivity of VEP, BAEP, SSEP or P300ERP for diagnosis of MHE was 13. 3%, 41. 7%, 46. 7% or 73. 3%, respectively, whereas the specificity was 77. 8%, 83. 3%, 70. 4% or 61. 1 %, respectively. The receiver operating characteristic curve revealed that the best sensitivity and specificity for the diagnosis of MHE was P300EERP (area under the curve was 0. 672, 95%CI 0. 572 * 0. 773). The agreement of NCT-A+DST with VEP, BAEP, SSEP or P300ERP was 43. 9%, 61. 4%, 57. 9% or 67. 5%. Conclusions P300ERP is a sensitive and specific method for the diagnosis of MHE. which can serve as a supplement but not instead of NCT-A+DST.

ABSTRACT

Objective To develop a new continent cutaneous diversion using a tapered ileum wrapped by rectus abdominis muscular flap. Methods Ten dogs underwent a procedure in which two 6 cm ileal segments were tapered and connected to the U-shaped reservoir which was detubularized by a 30-40 cm ileal segment with end-to-side anastomosis. A continent tube was created by a 6 cm length and 3 cm width rectus abdominis muscular flap with its blood supplied which was penetrated be-tween the mesenteric vessels of one tapered ileum (study tube) and wrapped around its periphery. The other tapered ileum (control tube) was brought out into the abdominal skin directly without any extra-mural support. Urodynamic studies were carried out at 1, 3 and 6 months postoperatively. The data of maximum inner pressure (MIP) and functional pressure length (FPL) of every study and control tubes at every study phase were recorded and statistics analysis were taken. Retrograde radiograms of the ef-ferent tubes were performed prior to sacrifice and histological examinations of study group were carried out after sacrificed. Results The average MIP in experimental group was significantly higher than that in control group at 1, 3 and 6 months post-operatively (P<0.01). However, no significant differences in MIP or FPL were found in study group between empty and full reservoir. In the control group, MIP was found rising significantly (P<0.001) and FPL (P<0.05) decreased sharply com-pared with empty and full reservoir. Retrograde radiograms confirmed that all efferent tubes were pa-tent and positioned straightly beneath the abdominal wall. Histological examination of study group at 6 months postoperatively demonstrated a layer of striated muscle around the serosa of the ileum. Conclusions The continent mechanism of tapered ileum could be enhanced by extramural support from wrapped rectus abdominis muscular flap. This technique could setup a reliable, easy catheterization continent cutaneous efferent tube.
