Background Free flap surgery for head and neck defects has gained popularity as an advanced microvascular surgical technique. The aims of this study are first, to determine whether the known risk factors such as comorbidity, tobacco use, obesity, and radiation increase the complications of a free flap transfer, and second, to identify the incidence of complications in a radial forearm free flap and an anterolateral thigh perforator flap. Methods We reviewed the medical records of patients with head and neck cancer who underwent reconstruction with free flap between May 1994 and May 2012 at our department of plastic and reconstructive surgery. Results The patients included 36 men and 6 women, with a mean age of 59.38 years. The most common primary tumor site was the tongue (38%). The most commonly used free flap was the radial forearm free flap (57%), followed by the anterolateral thigh perforator free flap (22%). There was no occurrence of free flap failure. In this study, risk factors of the patients did not increase the occurrence of complications. In addition, no statistically significant differences in complications were observed between the radial forearm free flap and anterolateral thigh perforator free flap. Conclusions We could conclude that the risk factors of the patient did not increase the complications of a free flap transfer. Therefore, the risk factors of patients are no longer a negative factor for a free flap transfer.

In volleyball, the most common injuries are anterior cruciate ligament (ACL) tears. For this reason, volleyball players frequently use knee brace as prophylactic and rehabilitation measures. The purpose of the study was to investigate the effects of knee brace on anterior cruciate ligament injuries risk factors during spike take off in female volleyball players. Fifteen female volleyball players were recruited and performed randomly spike take off with and without knee brace. Kinematics and ground reaction data were collected to estimate the anterior cruciate ligament injuries risk factors. The ACL risk factors are knee maximum flexion angle, thigh maximum adduction angle, thigh maximum internal rotation angle, shank maximum abduction angle, shank maximum external rotation angle, knee maximum extension moment and knee maximum abduction moment. Data were analyzed with paired samples t-test with Bonfferoni collection. Female volleyball players with knee brace had no significant results in knee maximum flexion angle, thigh maximum adduction angle, thigh maximum internal rotation angle, shank maximum abduction angle and shank maximum external rotation angle compare to without knee brace. Female volleyball players, however, with knee brace showed more reduced knee maximum extension moment and knee maximal abduction moment than without knee brace. In conclusion, Female volleyball players with knee brace reduced anterior cruciate ligament stress.

Objectives : Bell's palsy is the most common acute facial paralysis but its causes still unclear. At present, one of the most widely accepted cause is viral infections, and generally socioeconomic factors influence the viral infections. The purpose of this study is to investigate the relationship of incidence of facial palsy with socioeconomic factors. Methods : Seventeen patients with a acute facial palsy, who volunteered and completed all of the assessment measures participated. Using data on 17 participants, we examined the independent contribution of education, income, and occupation to a risk factor of severe facial palsy. Severity of global facial impairment was assessed by the facial disability index (FDI), the house-brackmann facial nerve grading system, WHO quality of life - bref (WHOQOL-BREF) and visual analogue scale (VAS) about discomfort of life. Results : There was no correlation between severity of facial palsy and gender, marriage, education, or occupation. Age greater than 60 years (p<0.05), and low monthly income(p<0.05), poor self-rated health was associated with greater severity of idiopathic facial paralysis. Conclusions : The number of subjects with facial palsy in our study (n-17) was small, and therefore generalization to larger patient populations might be unwarranted. But according to the outcome, we suggest that socioeconomic factors, especially low monthly income influence severity of bell's palsy.

Background: Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Despite this, few papers have reported the incidence and independent risk factors associated with PONV in the context of oral and maxillofacial surgery (OMFS). Therefore, we sought to determine the incidence of PONV, as well as to identify risk factors for the condition in patients who had undergone OMFS under general anesthesia. Methods: A total of 372 patients' charts were reviewed, and the following potential risk factors for PONV were analyzed: age, sex, body mass index, smoking status, history of PONV and/or motion sickness, duration of anesthesia, amount of blood loss, nasogastric tube insertion and retention and postoperative opioid used. Univariate analysis was performed, and variables with a P-value less than 0.1 were entered into a multiple logistic regression analysis, wherein P-values < 0.05 were considered significant. Results: The overall incidence of PONV was 25.26%. In the multiple logistic regression analysis, the following variables were independent predictors of PONV: age < 30 years, history of PONV and/or motion sickness, and anesthesia duration > 4 h. Furthermore, the number of risk factors was proportional to the incidence of PONV. Conclusions: The incidence of PONV in patients who have undergone OMFS varies from center to center depending on patient characteristics, as well as on anesthetic and surgical practice. Identifying the independent risk factors for PONV will allow physicians to optimize prophylactic, antiemetic regimens.

Purpose: The colorectal polyps has been regarded as a precursor of colon cancer, and the prevalence and mortality of colon cancer in Korea has increased due to westernized lifestyle and environmental factors. The purpose of this study was to investigate the characteristics and the risk factors on colorectal polyps in adults. Methods: The participants were 956 adults enrolled from health screen examinees underwent colonoscopy at the health promotion center in Seoul. Results: 49.5 percent of examinees has colorectal polyps and the most common sites were ascending colon (27.6%) and sigmoid colon (23.2%). The colorectal polyps showed a significant difference according to gender, age, and health behavior related characteristics including alcohol intake, exercise, and BMI. In male, the relative odds of having an colorectal polyps decreased as exercise (OR=1.74; 95% CI=1.01-1.04), and increased as BMI (OR=1.57; 95% CI=1.07-2.50) and age (OR=1.02; 95% CI=1.02-1.04). In female, it decreased as exercise (OR=2.49; 95% CI=1.52-4.10), and increased as age (OR=1.05; 95% CI=1.02-1.08). Conclusion: Based on the findings of this study, age and exercise were the influencing factors of colorectal polyps in health screen examinees. Therefore, effective exercise and appropriate health education program about colorectal polyps need to be developed and applied in nursing interventions to prevent colorectal polyps in the community dwelling adults.

Objective : The objectives of the present study were to characterize the natural course of initially non-operated traumatic acute subdural hematoma (ASDH) and to identify the risk factors of hematoma progression. Methods : Retrospective analysis was performed using sequential computed tomography (CT) images maintained in a prospective observational database containing 177 ASDH cases treated from 2005 to 2011. Patients were allocated to four groups as followings; 136 (76.8%) patients to the spontaneous resolution group, 12 (6.8%) who underwent operation between 4 hours and 7 days to the rapid worsening group (RWG), 24 (13.6%) who experienced an increase of hematoma and that underwent operation between 7 and 28 days to the subacute worsening group (SWG), and 5 (2.8%) who developed delayed aggravation requiring surgery from one month after onset to the delayed worsening group (DWG). Groups were compared with respect to various factors. Results : No significant intergroup difference was found with respect to age, mechanism of injury, or initial Glasgow Coma Scale. The presence of combined cerebral contusion or subarachnoid hemorrhage was found to be a significant prognostic factor. Regarding CT findings, mixed density was common in the RWG and the SWG. Midline shifting, hematoma thickness, and numbers of CT slices containing hematoma were significant prognostic factors of the RWG and the SWG. Brain atrophy was more severe in the SWG and the DWG. Conclusion : A large proportion of initially non-operated ASDHs worsen in the acute or subacute phase. Patients with risk factors should be monitored carefully for progression by repeat CT imaging.
