Yeungnam University Journal of Medicine 1991;8(1):32-41
This study was made to investigate the effect of adenoidectomy on dentofacial skeleton in naso-respiratory dysfunction children. The clinical material compromised the 24 children in a previous study who had naso-respiratory dysfunction and 24 children who were the nasal breathing with normal occlusion. The cephalograms were taken at the initial examination and 1 year later for the control group and experimental group the paired sample statistical analysis was performed. The results were as follows. 1. In cranial base variable, difference between two groups were not statistically significant. 2. In craniofacial variables, experimental group showed brachyfacial pattern but control groups didn't show significant growth pattern. 3. In maxillary variables, experimental group showed flattening the plane. 4. In mandibular variables, experimental group showed the decrease of mandibular plane angle and gonial angle. 5. In facial height variables, experimental group showed horizontal growth rotation.

The choice of operative procedures was determined by many factors, but the levator function is considered as the most important factor. Fox recommended that when the levator function was 2 to 9 mm, the patient should be treated by the levator resection and when the levator function was below 2 mm, the patient should be crated by frontalis suspension. But Collin recommended that when the levator function was below 4 mm, the brow suspension procedure got the better result. Beside that, many other authors recommended various opinions. Therefore, when levator function of the patients was between 2 and 4 mm, the choice of operative procedure was much confusing us. The aim of this study is to clarify which is better Procedures between levator resection and the frontalis transfer or orbicularis oculi muscle transfer among the patients with 2 to 4 mm of levator action. From Jan. of 1991 to Dec. of 1994, among 26 patients with 2 to 4 mm levator function, 13 cases of 10 patients were operated by levator resection, 21 cases of 16 patients were teated by frontalis transfer or orbicularis oculi muscle flap. The results were evaluated with the average 27 months of follow-up and we compared the result of the levator resection procedure with that of frontalis muscle transfer or orbicularis oculi muscle transfer. The preoperative average amount of ptosis is about 2.7 mm in cases with levator resection, about 4.0 mm in cases with frontalis muscle transfer or orbicularis oculi muscle flap transfer. The postoperative average amount of ptosis is about 1.7 mm in cases with levator resection about 2.14 mm in cases with frontail muscle transfer or orbicularis oculi muscle flap transfer and so the postoperative improvement of amount of ptosis is about 1.0 mm in cases with levator resection, about 1.86 mm in cases with frontails muscle transfer or orbicularis oculi muscle flap transfer. The major complication of levator resection method is undercorrection. However, the eyelid deformity due to excessive upward traction was more frequent in frontalis muscle flap technique.

An antrochoanal polyp is a solitary polypoid mass that arises from the maxillary sinus, and protrudes through the natural ostium into the middle meatus, and reaches the choana, The polyp does not differ histologically from an ordinary nasal polyp, which is composed of edematous, hyperplastic submucosal connective tissue stroma, and is relatively hypocellular, In this sequence of events. Its computed tomographic(CT)findings are characteristic. We retrospectively analyzed CT studies of nine cases, all of which showed similar CT findings; a solitary, homogeneous, hypodense mass without bony destruction that extends from the maxillary sinus through the widened ostium into the choana.

BACKGROUND: Discrepancies exist in the existing researches regarding the association between social capital and self-efficacy, and most of these researches have been done in developed countries. The aims of this study were to assess the independent association between individual social capital and self-efficacy and to assess the associations between individual social capital, self-efficacy and self-rated health. METHODS: Data were obtained from the Gyeongnam health survey (6,500 persons) conducted in 2008. A self-administered questionnaire was additionally administered to gather information on demographic variables, health behaviors, chronic diseases, self-efficacy, social capital, and self-rated health status. Total study population was 3,843 as those with chronic diseases were excluded. RESULTS: In males, trust was positively associated with confidence and preference to task difficulty, and participation was negatively associated with confidence and positively associated with regulation and preference to task difficulty. In females, trust was positively associated with confidence and preference to task difficulty and negatively associated with regulation. Participation was positively associated with preference to task difficulty. In males, the odds for self-rated health status was better for persons with confidence (95% confidence interval, CI 1.088-1.705), trust (95% CI 1.172-1.821) and participation (95% CI 1.268-2.117). In females, the odds for self-rated health status was better for those with confidence (95% CI 1.250-1.803), preference of task difficulty (95% CI 1.019-1.683) and participation (95% CI 1.024-1.555). CONCLUSIONS: High social capital measured at an individual level may promote self-efficacy and health status.

In order to find the degree of osseointegration at bone-implant interface of clinically successful implants, models including the 3.75mm wide, 10mm long screw type Branemarkimplant as a standard and cylinder, 15mm long, 5.0mm wide, two splinted implants, and implants installed in various cancellous bone density were designed. Also, the amount of load and material of prostheses were changed. The stress and minimum contact fraction were analyzed on each model using three-dimensional finite element method(I-DEAS and ABAQUS version 5.5) The results of this study were as follows. 1. 10mm long, 3.75mm diameter-screw type implant had 36.5~43.7% of minimum contact fraction. 2. Cylinder type implant showed inferior stress distribution and higher minimum contact fraction than screw type. 3. As implant length was increased, minimum contact fraction was increased a little, however, maximum principal stress was decreased. 4. Implants with a large diameter had lower stress value with slightly higher minimum contact fraction than standard screw type. 5. Two splinted implants showed no change of minimum contact fraction. 6. The higher bone density, the lower stress value. 7. The material of occlusal surface had no effect on the stress of the bone-implant interface.

Resveratrol has been reported to exert anticancer activity via modulation of multiple pathways and genes. In this study, we examined the effect of resveratrol on YD-10B human oral squamous cell carcinoma cells and its molecular mechanisms of action. We found that resveratrol inhibited the proliferation of YD-10B cells in a dose- and timedependent manner. The suppressive effect of resveratrol was accompanied by a reduction in Bmi-1 gene expression.We observed that silencing the Bmi-1 gene by small interfering RNA effectively downregulated the levels of GLUT1 mRNA and protein, which were also repressed by resveratrol. Bmi-1 silencing increased the number of YD-10B cells in S-phase arrest by approximately 2.3-fold compared with the control. In conclusion, the results of the present study demonstrate, for the first time, that resveratrol suppresses Bmi-1-mediated GLUT1 expression in human oral squamous cell carcinoma cells and suggest that the specific molecular targeting of Bmi-1 and/or GLUT1 expression can be combined with a chemotherapeutic strategy to improve the response of oral cancer cells to resveratrol.

The purpose of this study was to determine the factors which were responsible for delaying early diagnosis and optimal management of rheumatoid arthritis (RA) in Korea. We interviewed 109 outpatients diagnosed as RA being treated by rheumatologists, and we eventually analyzed 98 patients' data. The median length of time from symptom onset to the first visit to a medical doctor, to diagnosis, and visiting a rheumatologist were 8 weeks, 23 weeks, and 42 months respectively. The subspecialist with whom the patients consulted with for the longest time before visiting a rheumatologist were an orthopaedic surgeon for 51 patients, a Chinese herbal doctor for 19 patients, and a pharmacist for 16 patients. For early diagnosis and optimal management of RA in Korea, we believe that it is necessary to reduce the use of unconventional medical services such as Chinese herbal medicine and nonprescribed medication, and to emphasize rheumatologic and rehabilitative care in the early stage.

Aging processes are inevitably accompanied by structural and functional changes in vital organs. Skeletal muscle, which accounts for 40% of total body weight, deteriorates quantitatively and qualitatively with aging. Skeletal muscle is known to play diverse crucial physical and metabolic roles in humans. Sarcopenia is a condition characterized by significant loss of muscle mass and strength. It is related to subsequent frailty and instability in the elderly population. Because muscle tissue is involved in multiple functions, sarcopenia is closely related to various adverse health outcomes. Along with increasing recognition of the clinical importance of sarcopenia, several international study groups have recently released their consensus on the definition and diagnosis of sarcopenia. In practical terms, various skeletal muscle mass indices have been suggested for assessing sarcopenia: appendicular skeletal muscle mass adjusted for height squared, weight, or body mass index. A different prevalence and different clinical implications of sarcopenia are highlighted by each definition. The discordances among these indices have emerged as an issue in defining sarcopenia, and a unifying definition for sarcopenia has not yet been attained. This review aims to compare these three operational definitions and to introduce an optimal skeletal muscle mass index that reflects the clinical implications of sarcopenia from a metabolic perspective.

Eighty-three cases with severe blepharoptosis were treated by the superiorly based muscle flaps around eye including orbicularis oculi muscle, frontalis muscle, levator muscle. The selection of the muscle flaps were done in accordance with the levator function of patients. The orbicularis oculi muscle flap technique in 32 patients who have 2-5 mm levator function, 21 cases of the interdigitated orbicularis oculi-frontalis muscle flap for 1-3 mm levator function, frontalis muscle flap technique for less than 2 mm levator function, 22 cases of levator muscle resection for 2-8 mm levator function, 7 cases of levator plication for 5-9 mm levator function. The majority of patients recorded as satisfactory results. There has been no complete failure but there were 14 cases of undercorrection, 4 cases of overcorrection, 2 cases of exposure keratitis, 3 cases of corneal erosion, 2 cases of sensory loss, hematoma loss of wrinkle and a few cases of eyelid deformity such as notching, entropion, fading or unnatural fold. The orbicularis oculi muscle technique or the interdigitated orbicularis oculi-frontalis muscle flap technique offers several advantages over conventional frontalis muscle flap technique such as being a simple with a good operative field, single incision or supratarsal fold, no depression on the forehead, no risk of neurovascular injury and relatively easy technique with less complication. The levator resection or levator plication could offer good results by careful selection of patients. In conclusion, we would like to say that the interdigitated frontalis orbicularis oculi muscle flap technique is best in cases with less than 2 mm levator function, orbicularis oculi muscle flap technique in 2-4 mm levator function, levator resection in 4-8 mm levator function, levator plication in more that 8 mm levator function.
