Ameloblastic fibro-odontoma(AFO) is a rare mixed odontogenic tumor. It is composed of connective tissue characteristic of an ameloblastic fibroma and calcified tissue as a complex or compound odontoma. AFO usually presents itself as an asymptomatic swelling of jaw or failure of tooth eruption. The lesion usually occurs in individual less than 30 years old. The differential diagnosis of this tumor includes odontoma, ameloblastoma, and ameloblastic fibroma. This report describes an ameloblastic fibro-odontoma occurring in maxilla of sixteen-year-old female. The lesion was treated by surgical enucleation and curettage without extraction of the involved canine(#23). This patient has shown no sign of recurrence during postoperative 34 months. So we report our case with review of literatures.

OBJECTIVE: Acute subdural hematoma (ASDH) is generally considered a condition that should be managed surgically. However, some patients initially receive conservative treatment, a subset of whom require surgical intervention later. This study aimed to evaluate the predictors of delayed surgical intervention in ASDH patients who are initially managed conservatively. METHODS: From January 2007 to December 2015, 842 patients diagnosed with ASDH were treated at our institution. Among them, 158 patients with convexity ASDH were initially treated conservatively. Patients were divided into a delayed surgery group and a conservative group. Demographic characteristics, past medication and medical histories, and radiological and laboratory data were collected by retrospective chart review. Independent risk factors were identified with univariate and multivariate analyses. RESULTS: Twenty-eight patients (17.7%) underwent delayed surgical intervention. Their mean age was 69.0 years, and 82.1% were male. Hypertension, diabetes mellitus, and heart disease prevalence and use of anti-platelet agents did not significantly differ from the conservative group. However, age (p=0.024), previous cerebral infarction history (p=0.026), increased maximal hematoma thickness (p<0.001), midline shifting (p=0.001) and accompanying subarachnoid hemorrhage (p=0.022) on initial brain computed tomography (CT) scan, low hemoglobin level (p<0.001), high leukocyte count (p=0.004), and low glucose level (p=0.002) were significantly associated with delayed surgical intervention. In multivariate analysis, increased maximal hematoma thickness (odds ratio [OR]=1.279, 95% confidence interval [CI] 1.075–1.521; p=0.006), low hemoglobin level (OR=0.673, 95% CI 0.467–0.970; p=0.034), and high leukocyte count (OR=1.142, 95% CI 1.024–1.272; p=0.017) were independent risk factors for delayed surgical intervention. CONCLUSION: Due to the high likelihood of delayed surgical intervention among minimal ASDH patients with a thicker hematoma on initial brain CT, lower hemoglobin level, and higher leukocyte count, these patients should receive more careful observation.

Esmolol is a cardioselective beta-blocker with a very rapid onset of action and a short half-life. Labetalol is a combined alpha- and beta-adrenoceptor blocking agent. It is a nonselective antagonist at beta-adrenoceptors and a competitive antagonist of postsynaptic alpha 1-adrenoceptors. A 51 year old female patient was transferred to the operating room for performing spinal fusion under general anesthesia. She had no operation and medication history. The initial heart rate was 150 beats/min. Despite administering several bolus injections of esmolol, the heart rate was not decreased to under 130 beats/min. But the heart rate was decreased to 100 beats/min after the administration of labetalol 5 mg and this rate was maintained without an additional injection. The vital signs were stable until the operation was finished and the patient recovered uneventfully in the recovery room. The postoperative laboratory findings revealed that she had hyperthyroidism. We report here on an anesthetic experience of effective labetalol treatment for esmolol-resistant tachycardia in a patient who was under general anesthesia.

The acromioclavicular separation (AC separation) is a common injury, which is often accompanied by the rupture of the coracoclavicular ligament (CC ligament) in severe occasions. In rare forms of AC separation, the fracture of the coracoid process would occur rather than the rupture of the CC ligament. Only 31 cases of such injury have been reported in the English literature. We present 2 additional cases with literature review. The fracture of the coracoid process is not readily seen on anteroposterior shoulder radiograms. Severe AC separation without widening of CC distance on anteroposterior shoulder radiogram heralds the fracture of the coracoid process.

PURPOSE: This research evaluated clinical outcomes of two types of hydroxyapatite (HA)-coated implants: OT (Osstem TS III-HA, Osstem implant Co., Busan, Korea) and ZM (Zimmer TSV-HA, Zimmer dental, Carlsbad, USA). MATERIALS AND METHODS: The research was conducted on 303 implants (89 of OT, 214 of ZM), which were placed from January 16, 2010 to December 20, 2012. The prognosis was evaluated in terms of success rates, survival rates, annual marginal bone loss, and implant stability quotients (ISQ). The samples were classified into immediate, early, conventional, and delayed groups according to the loading time. RESULTS: Overall, there were no significant differences between OT and ZM in success rates, survival rates, and annual marginal bone loss, except for the result of secondary stability. OT showed 77.83 ± 8.23 ISQ, which was marginally higher than 76.09 ± 6.90 ISQ of ZM (P < .05). In terms of healing periods, only immediate loading showed statistically significant differences (P < .05). Differences between OT and ZM were observed in terms of two indices, the annual marginal bone loss (0.17 ± 0.58 mm/year < 0.45 ± 0.80 mm/year) and secondary stability (84.36 ± 3.80 ISQ > 82.48 ± 3.69 ISQ) (P < .05). OT and ZM did not have any statistically significant differences in early, conventional, and delayed loading (P>.05). CONCLUSION: OT (97.75%) and ZM (98.50%) showed relatively good outcomes in terms of survival rates. In general, OT and ZM did not show statistically significant differences in most indices (P>.05), although OT performed marginally better than ZM in the immediate loading and 1-stage surgery (P < .05).

The mentalis muscle is a paired muscle originating from the alveolar bone of the mandible. This muscle is the main target muscle for botulinum neurotoxin (BoNT) injection therapy, which aims to treat cobblestone chin caused by mentalis hyperactivity. However, a lack of knowledge on the anatomy of the mentalis muscle and the properties of BoNT can lead to side effects, such as mouth closure insufficiency and smile asymmetry due to ptosis of the lower lip after BoNT injection procedures. Therefore, we have reviewed the anatomical properties associated with BoNT injection into the mentalis muscle.An up-to-date understanding of the localization of the BoNT injection point according to mandibular anatomy leads to better injection localization into the mentalis muscle. Optimal injection sites have been provided for the mentalis muscle and a proper injection technique has been described. We have suggested optimal injection sites based on the external anatomical landmarks of the mandible. The aim of these guidelines is to maximize the effects of BoNT therapy by minimizing the deleterious effects, which can be very useful in clinical settings.

PURPOSE: To compare results between minimally invasive plate osteosynthesis using a periarticular plate and intramedullary nailing in distal tibial metaphyseal fractures in two treatment groups. MATERIALS AND METHODS: Sixty-one cases of distal tibial metaphyseal fractures from December 2008 to December 2009 were evaluated. The minimal follow-up period was 12 months. Thirty patients treated by minimally invasive plate osteosynthesis using a periarticular plate were Group A; 31 patients treated by intramedullary nailing were Group B. We compared and analyzed the results of each group by radiological and clinical assessments. RESULTS: The mean bony union time was 16.4 weeks in Group A and 17.2 weeks in Group B. The mean operation time was 45 minutes in Group A and 48 minutes in Group B. The mean radiation exposure times were 4.2 minutes and 4.8 minutes, respectively. VAS scores were 0.7 points and 0.5 points in each respective group. In Group A, the VAS score was 1.7 points when we applied pressure on the skin around the plate. The mean Olerud and Molander Ankle Score was 87.4 points and 86.3 points, respectively. A superficial wound infection occurred in 1 case in each group, and angular deformities more than 5 degrees occurred in 2 Group B cases. CONCLUSION: No significant differences in results were observed between the two groups. However, a higher incidence of angular deformity was seen in the intramedullary nailing group. Therefore, we must be careful during surgery.

PURPOSE: Excessive weight bearing from obesity may induce pains in the lower extremity and resulting functional abnormality. Here we aimed to identify the relationship, it is intended to identity relationship obesity has with diabetic foot ulcer, sensory function, and blood circulation in diabetic patients. MATERIALS AND METHODS: We included patients who hospitalized or visited the department of orthopedic surgery for the treatment of diabetic foot ulcer, between January 2010 and December 2015. Among them, those aged over 30 years, diagnosed with diabetes with a progression of more than one year, and an HbA1c level of less than 7.5% were included for final analysis. For obesity, body mass index (BMI) was used, those with a BMI of over 18.5 kg/m2 were included. Using the Asian cut point of World Health Organization, patients were classified into normal, overweight, or obese. For foot ulcers, patients were classified using the Wagner ulcer classification. For sensory function, it was measured by scoring it with Semmes-Weinstein monofilament of International Working Group on the Diabetic Foot (IWGDF). Moreover for blood circulation, ankle-brachial index (ABI) was measured. RESULTS: For the sensory function, it was found that the overweight group obtained the highest score and the obesity group obtained the lowest score. For ABI, the overweight group scored the highest and the normal group scored the lowest. Moreover diabetic foot ulcer was the highest in the obesity group and the lowest in the normal group. From these results, it was considered that BMI had no relationship with sensory or blood circulation of the feet. However, the relationship between the diabetic foot ulcer and BMI showed statistical significance; according to the result of regression analysis, BMI of diabetic patients had a positive correlation with diabetic foot ulcer. CONCLUSION: This study showed that the sensory function and blood circulation of the feet had no relationship with diabetic foot ulcer; however, BMI appears to have a positive correlation with diabetic foot ulcer. Moreover, it seems to be a good index for determining the risk of diabetic foot ulcer.
