Objective To evaluate the clinical outcome of the buccal fat pad flap in reconstruction of defects of the oral mucosa. Methods From May 1998 to July 2004, 42 patients with oral mucodefects were treated with buccal fat pad flap. Of them, there were 26 males and 16 females, aging 25-76 years. The defect was caused by buccal squamous carcinoma in 7 cases, by buccal leukoplakia in 5 cases, by squamous carcinoma of soft palate in 7 cases, by adenoid cystic carcinoma of palate in 8 cases, by carcinoma of maxillary sinus in 6 cases, by maxillo-alveolar angioma in 5 cases and by keratocyst of maxilla in 4 cases. The locations were buccal mucosa, maxillary sinus and soft palate. The size of defect ranged from 3.0 cm×3.0 cm to 6.5 cm×4.0cm.Results Forty-one cases achieved healing by first intention, except one case because of large defect. Edema faded and epithelization occurred after 4 weeks of operation. Complete epithelization was observed after 6 weeks of operation. Thirty-five cases were followed up 3 months to 5 years. Therewere no obvious differences in layers, color, elasticity, and texture between repaired region and adjacent mucosa. Conclusion The buccal fat pad flap is useful in reconstructing the muco-defects (less than 6.5 cm in diameter) of the posterior maxilla and buccal region without considerable complication. The multiplex blood supply, facility in accessing and minimal donor site morbidity make it a reliable soft tissue graft. The main shortcoming is its limited size.
Objective To compare the reconstructive method of oral and maxillofacial defect with free tissue flaps. Methods The clinical materials were collected from 1 973 reconstructive cases between January 2000 and June 2004 and analyzed in terms of the distribution of age, gender,disease type, defect location, reconstructive method and the incidence of vascular crisis of free flaps as well as success rate of free flap respectively. SAS 6.12 was adopted for statistical analysis. Results A total of 1 973reconstructive cases includded 764 in middle age (＞45 years to ≤60 years, 38.72%), 527 in old age (＞60 years, 26.71%), 450 young adults (＞28 years to ≤45 years, 2281%), 187 in young age (＞14 years to ≤28 years, 9.48%) and 45 children(≤14 years, 2.28%). The ratio of male to female was 1.5∶1. The ratio of benign to malignancy lesion was 1∶1.94. The tongue defect accounted for 20.63%, followed by mandibular defect(1738%), parotid defect(13.74%)，buccal defect(12.72%), maxillary defect(8.16%), oral pharynx defect (7.60%), floor of mouth defect(5.68%) and others (14.09%). Vascular free flap transfers accounted for 45.82%(90.4), followed by axial flap(38.17%,753), random flap(10.19%,201), avascularizedbone graft (1.52%, 30) and others(4.30%, 85). The most frequently used flap was the forearm flap(594 cases), followed by the fibula free flap(143 cases) and the pedicled pectoralis major myocutaneous flap(369 cases); these three flaps accounted for 56.06% (1 106/1 973).In 47 free tissue flaps(5.20%) having vascular crisis, 30 were saved (63.83%). The success rate of total free tissue flaps was 98.19%(923/940). Conclusion The majority of reconstructive cases of oral and maxillofacial defects is the middle aged andthe old aged male patients with malignancy. The tongue defect accounts for about one fifth of all the cases. The vascularized free flap has a high success rate, so it is a main method for reconstruction of oral and maxillofacial defects. The forearm flap, the fibular free flap and the pedicled pectoralis major myocutaneous flap are the main management for repairing oral and maxillofacial defects.
Objective To develop an evaluation tool for the screening of high risk population for oral complications in critically ill patients, which can be performed accurately and scientifically. Methods Basing on the related foreign oral assessment scale, combined with the method of brainstorming, expert consultation, method of clinical status and so on, the item pool of the assessment scale was determined. Five nursing experts and two oral experts assessed the content validity and 50 ICU nurses were tested. Then, the screening accuracy of the assessment scale was proved by application in 100 critically ill patients selected randomly. Results The Cronbach’s a coefficient of final version of the High Risk Assessment Scale for Oral Complications in Critically Ill Patients (including seven parts contents of oral health assessment and oral pH value test) was 0.815, the content validity index (Sr-CVI/Ave) was 0.932. The results of 50 nurses to the 91.2% assessment items of the assessment scale were very important and important. For screening related indicators of oral complications in high-risk patients, the sensitivity of the assessment scale was 97.53%, the specificity was 94.11%, the positive predictive value was 98.75%, the negative predictive value was 88.89%, and the crude agreement was 95%. Conclusion There are good reliability, validity and a high accuracy of screening test in the High Risk Assessment Scale for Oral Complications in Critically Ill Patients. It can be used for screening patients at high risk for oral complications in critically ill patients, and help clinical nurses to complete the oral health status of the critically ill patients quickly.
Objective To compare and evaluate the effectiveness and safety of 30ug ethinyl estradiol /150ug desogestrel versus 30ug ethinyl estradiol /75ug gestodene. Methods We searched MEDLINE (1990 to 2007), EMBASE (1990 to 2007), POPLINE (1990 to 2007), Cochrane Central Register of Controlled Trials (Issue 2, 2007), EMBASE (1990 to 2007) and The Cochrane Library (Issue 2, 2007). Four relevant journals were also hand searched. Randomized controlled trials (RCTs) comparing ethinyl estradiol with desogestrel were collected. The quality of the included studies was assessed and data were collected by two reviewers independently. Meta-analyses were performed with The Cochrane Collaboration’s RevMan 4.2.10 software.Results Six studies involving 3,143 patients were included. Meta-analyses found no significant difference in contraceptive effect between 30ug ethinyl estradiol /150ug desogestrel and 30ug ethinyl estradiol /75ug gestodene (Pgt;0.05). During six months of follow-up, patients receiving 30ug ethinyl estradiol /150ug desogestrel had a higher incidence of irregular bleeding (RR 1.50, 95%CI 1.27 to 1.78; Plt;0.00001); and a lower incidence of vomiting (RR 0.18, 95%CI 0.04 to 0.78; P=0.02]; but higher incidences of breast tenderness, nervousness, headache, chloasma, edema, dyspareunia and varicose (RR 1.23 to 2.69; 95%CI 1.02 to 6.37, Plt;0.05). No significant differences were noted in discontinuation between 30ug ethinyl estradiol /150ug desogestrel and 30ug ethinyl estradiol /75ug gestodene. Conclusion Ethinyl estradiol was similar to desogestrel in terms of the contraceptive effect, while the use of desogestrel might be associated with less irregular bleeding and other common adverse events. As the existing data have a high risk of bias, the current evidence is insufficient and further high-quality randomized controlled trials are needed.
Objective A systematic review was conducted based on the domestically published literature for improving the quality of oral nursing care.Methods The terms "oral nursing care", "oral hygiene care", "mouth care" were used to search related studies in Chinese databases (up to April 30, 2004) along with handsearching additional studies. Four authors screened and selected the studies, appraised the methodological quality and extracted data from these selected studies. The results were presented by description or Meta-analysis. Results A total of 28 studies were identified, of which 6 were excluded. The methodological quality varied among the studies, 7 scored as B, 15 as C (11 randomized controlled trials, 4 quasi-randomized trials). A total of 2 372 patients were observed including some were critically ill, or intubated, or receiving radiotherapy or chemotherapy or undergoing surgical operations.Six authors of RCT replied and four of them provided more information on methods of randomization. Data analysis revealed that traditional oral nursing procedure was suitable for the severely sick patients who could not take self-care. Brushing and gargling were suitable for conscious patients who could use their hands. Tea and toothpaste were safe, economical and convenient oral nursing agents. Oral pH was a useful index for the selection of oral nursing agents and mouthwashes. A gargle containing sodium bicarbonate was used in the acidic oral environment and reduced fungal infection. The mouthwash with tea polyphenols had good effect for oral health, and might be as the first choice for prophylaxis of stomatitis induced by radiotherapy and/or chemotherapy. Some mouthwashes developed by Chinese herbs improved oral health efficiently. Some disinfectants with good safety and low toxicity might be used as supplementary agents in oral nursing care. Conclusions Oral nursing care procedures have improved the efficiency of oral care. But the conclusion should be verified by more, well designed randomized controlled trials involving a collaborative multidiscipliary health care professionals. Oral nursing care practice needs to be evidence based.
Objective To report 4 methods of reconstructing soft tissue defects in oral and maxillofacial regions after tumors resection using cervical pedicle tissue flaps. Methods One hundred seventy-two soft tissue defects were repaired with cervical myocutaneous flaps after resection of oral and facial cancer( 165 cases of squamous cell carcinoma and 7 cases of salivary carcinoma). The clinical stage of the tumors was stage Ⅰ in 21 cases, stage Ⅱ in 116 cases and stage Ⅲin 35 cases. Primary sites of the lesions were the tongue (59 cases), buccal mucosa (55 cases), lower gingiva (26 cases), floor of the mouth (25 cases), parotid gland (4 cases) and oropharynx (3 cases). Infrahyoid myocutaneous flaps were used in 60 cases, platysma flaps in 45 cases, sternocleidomastoid flaps in 59 cases and submental island flaps in 8 cases. The sizes of skin paddle ranged from 2.5 cm×5.0 cm to 5.0 cm ×8.0 cm. Results Among 153 survival flaps, there were55 infrahyoid myocutaneous flaps, 40 platysma flaps, 52 sternocleidomastoid flaps and 6 submental island flaps. There were 11 cases of total flap necrosis and8 cases of partial flap necrosis. The success rates were 91.67%(55/60) for infrahyoid myocutaneous flap, 88.89%(40/45) for platysma flap, 88.14% (52/59) for sternocleidomastoid flap and 75%(6/8) for submental island flap. After a follow-up of 3 11 years(5.7 years on average) among 101 cases local reccurence in 18 cases, cervical reccurence in 4 cases, distance metastasis in 2 cases. The survical rate at 3 years were 83.17%(84/101). Conclusion Cervical pedicle tissue flaps haveclinical value in reconstruction of small and medium-sized soft tissue defects after resection of oral and maxillofacial tumors.
Objective To assess the evidence of Cochrane systematic reviews relating to oral hygiene care. Methods Issue 3, 2008 of The Cochrane Library was searched for systematic reviews relating to oral hygiene care. Results Four systematic reviews with the forty-five randomized controlled trials (RCTs) were included. The methods of forty-five studies were of lower quality with high risk of various biases. Conclusion There is insufficient evidence to support oral hygiene care. The overall quality of RCTs about oral hygiene care is generally low. Analysis of the included trials shows some trials have no clear description of randomization methods, allocation concealment, sample size calculation, and intention-to-treat analysis. To improve the quality of reporting of RCTs, Clinical Trial Registration and Revised consolidated standards of reporting trial (CONSORT) statement should be introduced as guidelines into the trial design.
ObjectivesTo explore the effect of preoperative and early postoperative oral carbohydrate on the prognosis of patients undergoing colorectal cancer surgery.MethodsA total of 184 patients who underwent laparoscopic colorectal cancer surgery at the First Affiliated Hospital of Chongqing Medical University from March 2019 to July 2019 were selected. They were randomly divided into two groups: the drinking group (n=93) and the non-drinking group (n=91) using a random number table method. The drinking group drank 5 mL/kg carbohydrate clear drink 2 hours before surgery and began to take carbohydrate orally 4 hours after surgery. The non-drinking group was not allowed to drink for 8 hours before surgery and began to drink after exhaustion. The time to first flatus, first defecation in the two groups were observed. The incidence of complications (including aspiration, postoperative intestinal obstruction, anastomotic leakage, incision infection, postoperative nausea and vomiting, and pulmonary infection), postoperative length of stay and total cost of stay in the two groups were observed.ResultsCompared with the non-drinking group, the time to first flatus (Z=−8.009, P<0.001), the time to first defecation in the drinking group was significantly shorter (Z=−6.263, P<0.001), the incidence of postoperative complications was significantly lower (χ2=12.603, P<0.001), the length of postoperative hospitalization was shorter (t=−5.891, P<0.001). There was no statistical difference in total hospital expenses between the two groups (t=−1.860, P=0.065).ConclusionsOral administration of carbohydrate before and early after colorectal cancer surgery is safe and feasible, which can significantly reduce the overall complications, shorten the length of postoperative hospital stay, and promote the rapid recovery of patients.
The wister rats with cirrhotic portal hypertension induced by carbon tetrachloride/ethanal were divided into four groups;①distal splenocaval shunt(DSCS);②portal azygous devascularization (PAD);③mesocaval shunt side to side (MCS);and ④the conrol. Oral glucose toleronce test (OGTT), and glucagon loading test (GLT) were performed on them. The results revealed that the hepatic reserve function of the rats with DSCS and PAD had significant difference as compared with the control (Ｐ＜0.05), but that of the rat with MCS had no significant difference as compared with the control (Ｐ＞0.05).The present study indicates that the hepatic reserve function of rats with DSCS and PAD is better than that of the rats with MCS.
