Ameloblastoma is an aggressive benign odontogenic epithelial tumour that may arise from the enamel organ, remnants of dental lamina, or the lining of an odontogenic cyst. It is usually categorized into solid or multicystic, unicystic, and peripheral types. Treatment ofameloblastomas include conservative methods such as marsupialisation, enucleation, and curettage; and radical treatments such as marginal or segmental resection. Radical treatments have resulted in lower recurrence rates; however, may also encounter esthetic, functional, and reconstructive problems. Unicystic ameloblastoma has been considered less aggressive and a lower recurrence tendency. Thus, many authors have recommended conservative treatment in cases of unicystic ameloblastoma. An 11 year-old boy presented with displaced second and third molars by luminal unicystic ameloblastoma in the mandible. Cyst enucleation, curettage, and third molar extraction were done. No signs of recurrence or esthetic problems such as facial asymmetry were seen radiologically and clinically, up to 8 years 2 months postoperatively.

Cleidocranial dysplasia is rare inherited skeletal dysplasia. It was first reported by Martin in 1765. Subsequently, Marie and Sainton independently documented the criteria of the disease. Cleidocranial dysplasia is a bone disorder caused by a defect in the CBFA1 gene of chromosome 6p21. This gene guides osteoblastic differentiation and appropriate bone formation. Patient with cleidocranial dysplasia has maxillary deficiency, high and narrow palate, prolonged retention of primary teeth, unerupted permanent teeth and supernumerary teeth. Therapeutic options in these patients include of autotransplantation of selected impacted teeth, forced eruption of permanent teeth, full denture, overdenture and implant-supported prosthesis. We report a patient with cleidocranial dysplasia. This patient was treated with implant supported bar overdenture. Despite of gene defect that affects osteoblastic activity, bone remodeling and osseointegration occurred in our patient. So, we report this case with review of literature.

Carcinoma ex pleomorphic adenoma is transformed at the incidence of 1-20% in pleomorphic adenoma and frequently recurred. It accounts for 10% of all malignant salivary tumors and its average age of occurrence is 60s. It will present in a large, long-standing pleomorphic adenoma or in one that was previously treated but has recurred. According to cell composition in malignant cell carcinoma, and clear cell adenocarcinoma. Most (75%) occur in parotid gland, while about 20% occur in the minor gland of the oral mucosa. The metastasis rate to regional lymph node is about 25%, and to distant organs about 33% and the 5-year survival rates are 40%. Though the treatment of the carcinoma ex pleomorphic adenoma is not established, it is treated ideally with and extensive resection, neck dissection, postoperative radiotherapy, and chemotherapy. When occurred in parotid gland, facial paralysis is reported. With a review of literatures, we report a case of carcinoma ex pleomorphic adenoma which operated with total parotidectomy and supraomohyoid neck dissection.

This clinical study was performed to evaluate whether supplementation of proton pump inhibitor (PPI)-based triple therapy with Korean red ginseng can enhance Helicobacter pylori (H. pylori) eradication and reduce levels of halitosis-associated volatile sulfur compounds (VSCs) in the stomach. Seventy-six patients were randomized into an eradication regimen-only group (n=45) or an eradication regimen plus 10 weeks of Korean red ginseng supplementation group (n=31). The eradication regimen consisted of PPI b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.. for seven days. Korean red ginseng supplementation commenced on the last day of the eradication regimen. $^{13}C$-urea breath test and halimeter measurements were performed prior to protocol repetition. By intention-to-treat analysis, the H. pylori eradication rate in the Korean red ginseng group (77.4%, 24 of 31) was higher than that in the control group (45.0%, 26 of 45). However, by per protocol analysis, the eradication rate in the Korean red ginseng group was significantly higher than that in the control group (92.3%, 24/26 vs. 69.4%, 26/38; p<0.05). H. pylori infection was significantly associated with increased VSC levels. However, VSC levels decreased significantly in the Korean red ginseng group (p<0.05). In conclusion, supplementation of triple therapy with Korean red ginseng increased the H. pylori eradication rate and led to significant reductions in VSC levels, suggesting the usefulness of this substance in combating H. pylori infection.

Purpose: Crushing injuries by car tires result from a combination of friction, shearing, and compression forces and the severity of injury is influenced by the acceleration. Because car-tire injuries of the lower leg in children are common these days but they have received little attention; thus, our purpose was to look closely into this problem. Methods: A retrospective analysis was conducted of data from children under 15 years old age who visited an emergency department because of a car-tire-related crushing injury to the lower leg in pedestrian traffic accident from January 2008 to September 2012. The patient's age, sex, site of injury, degree of injury, associated injuries, type of surgery, and complications were reviewed. Results: There were 39 children, the mean age was 8.0 years, and 71.8% were boys. The dorsal part of the leg was involved most frequently. According to the severity classification, 15 children were grade I, 6 were grade II, and 18 were grade III. Among 24 patients, 13 were treated with skin graft and 3 were treated using a sural flap. Twelve patients developed complications, such as hypertrophic scarring, contractures, and deformities with significant bone loss. Conclusion: Various degrees of skin or soft tissue defects were caused in children by car tires. In this study, patients were often also had tendon or bone damage. Proper and timely initial treatments are needed to reduce the incidence of infection, the number of operative procedures, and the hospital stay.

Background and Objectives: A nerve conduction study (NCS) has been known as a useful method to evaluate the therapeutic effect of operation in carpal tunnel syndrome (CTS). To evaluate the temporal relationship between symptomatic and electrophysiological improvement, we compared the preoperative symptoms and electrophysiological results with postoperative those. Methods: We analyzed the NCS changes before and after minimal release of carpal tunnel in 26 patients (34 hands) with CTS. The time of postoperative symptomatic changes, postoperative electrophysiological changes and temporal relationship between symptomatic and electrophysiological changes were evaluated. Results: The mean age was $49{\pm}13$ years. The proportion of males to female was 8 and 92 percent. The median interval days between date of operation and those of postoperative NCS was 28.5 days. Postoperative symptoms improved in 17 hands, slightly improved in 13 hands, and have not changed in 4 hands. Electrophysiological improvements after operation were observed in 26 hands, and mostly appeared within 2 months. Symptomatic relief accompanied with electrophysiological improvement reported in 13 hands (50%). Moreover, the four hands with symptom, not relieved by decompression, showed electrophysiological improvement. Conclusions: In this study, electrophysiological improvement was in consistency with symptomatic relief to some extent, but we got the result of disagreement between electrophysiological and symptomatic improvement.

Purpose: The purpose of this study was to compare prescription patterns and clinical features according to clinical departments in sedative-hypnotic intoxication. Methods: This was a retrospective study of histories, substances of poisoning, acquisition routes, clinical courses, and outcomes of patients treated for acute intoxication in a single emergency medical center from January, 2011 to December, 2013. Results: A total of 769 patients were treated for acute intoxication, 281 patients ingested sedative hypnotics during the study period. Among 281 patients, 155 patients were prescribed by psychiatric department and 80 patients were prescribed by non-psychiatric department. Benzodiazepines were more likely to be prescribed by psychiatrists, and zolpidem was preferred by non-psychiatrists (p<0.001). Non-psychiatrists were more likely to prescribe short acting benzodiazepines than psychiatrists (p<0.001). However, there was no statistically significant difference in the clinical outcomes, including prevalence of admission to ICU, ventilator care, and length of stay in ICU. In patients prescribed by non-psychiatrists, there were more patients prescribed without psychiatric diagnosis and diagnosed as major depression disorder after hospitalization. Conclusion: To promote rational prescribing of sedative hypnotics, proper psychiatric evaluation should be performed before prescribing, and educational programs including the contents of interactions and side effects of sedative hypnotics are needed.

Background: Lone workers are generally defined as individuals who work alone without supervision, including self-employed people. While lone workers are considered a vulnerable group in some countries, there is a lack of research on their health status in domestic studies. Globally, the number of lone workers has been increasing, and this trend has been further accelerated since the coronavirus disease 2019 (COVID-19) pandemic with the rise of remote work. Methods: The study analyzed data from 44,281 participants, excluding unpaid family workers, soldiers, and those with missing data. Lone workers were defined as individuals who reported having no colleagues with the same job at their current workplace. Self-rated health status was categorized as "good" or "poor." Results: This study found a statistically significant higher number of lone workers among women compare to men. The largest occupational category for lone workers was service and sales workers, followed by agriculture and fisheries workers. A majority of non-lone workers reported working 40 hours or less per week, while the majority of lone workers reported working 53 hours or more per week. In addition, lone workers had significantly poorer health status evaluations compared to non-lone workers (odds ratio: 1.297; 95% confidence interval: 1.165-1.444). Conclusions: Further research is needed to investigate the causal relationship between lone work and health, using data collected after the COVID-19 pandemic.
