Distal humerus fractures (DHFs) are challenging to treat due to the locally complex osseous and soft tissue anatomy. Adequate exposure of the articular surface of the distal humerus is crucial when performing an anatomical reconstruction of the elbow. Even though "triceps-on" approaches are gaining popularity, one of the most commonly used surgical treatments for DHF is olecranon osteotomy. The incidence of complications related to this approach is unclear. This review was performed to assess the type and frequency of complications that occur with the olecranon osteotomy approach in the treatment of DHF. A literature search was conducted in the PubMed/Medline, Embase, and Cochrane Library digital databases up to February 2020. Only English articles describing complications of olecranon osteotomy in the treatment of DHF were included. Data on patient and surgical characteristics and complications were extracted. Statistical analysis was performed using SPSS. A total of 41 articles describing 1,700 osteotomies were included, and a total of 447 complications were reported. Of these 447 complications, wound infections occurred in 4.2% of osteotomies, of which 1.4% were deep infections and 2.8% were superficial. Problems related with union occurred in 3.7% of osteotomies, 2% of which represented non-union and 1.7% delayed union. The high risk of complications in olecranon osteotomy must be considered in the decision to perform this procedure in the treatment of DHF.

We retrospectively evaluated the clinical and imaging features of 6 patients with bone hydatid disease confirmed by surgery and pathological examination. Among the 6 patients, 2 were infected with Echinococcosis granulosus metacestode and 4 were infected with E. multilocularis metacestode. The 2 cases with cystic echinococcosis were diagnosed by computed tomographic (CT) examination, and other 4 cases were diagnosed by magnetic resonance (MR) imaging. On the initial evaluation, 1 case each was misdiagnosed as a giant cell tumor or neurogenic tumor, and 2 were misdiagnosed as tuberculosis. The imaging manifestations of bone hydatid disease are complex, but most common findings include expansive osteolytic bone destruction, which may be associated with sclerosing edges or dead bone formation, localized soft tissue masses, and vertebral lesions with wedge-shaped changes and spinal stenosis. Combining imaging findings with the patient's epidemiological history and immunological examinations is of great help in improving the diagnosis and differential diagnosis of bone hydatid disease.

A wild Whooper swan (Cygnus Cygnus) with limping due to an injured left pelvic limb in an accident was rescued on the seashore and transferred to the Jeju Wildlife Rescue Center on November 23rd, 2020. On physical examination, its body condition score was 1 out of 5 due to starvation and dehydration. The left coxofemoral joint was also examined by careful palpating and estimating the damage. Moderated soft tissue swelling and crepitus surrounding the hip joint were confirmed. Radiography and computed tomography (CT) were used together for an accurate diagnosis of the joint. By radiographs readings, it was difficult to accurately confirm the condition of the proximal femur due to superimposition of the synsacrum and internal organs. However, signs such as avulsion fracture of the femoral head and a few fragments around the joint were revealed by CT imaging. Besides, through three-dimensional (3D) image analysis of CT, the dislocated area and condition of the left hip joint could be accurately and easily confirmed. The diagnostic process showing in this paper could be used as a good reference for diagnosing coxofemoral joint luxation in wild swan.

Special Practitioner exists based on the need for special fields that are required to manage difficult patients with specialized skills distinguished from General practitioner. The purpose of dental specialist system is to manage patients who are not treatable by general practitioner by training doctors specializing in one specific field, thereby, enhancing health of the public. Oral Medicine deals with orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. In these days, living environments of city life bring about increase in stress which ultimately lead to increase in prevalence of temporomandibular disorder, oral soft tissue disease, neuropathies such as trigeminal neuralgia, and hence, the number of patients seeking help of those symptoms tend to increase. The purpose of this study was to analyze the rate of referrals and the routes of patients seeking help by investigating 3,707 patients who visited Department of Oral Medicine, College of Dentistry, Yonsei University, from August, 2004 to April, 2005. The results were as follows: 1. The types of disease referred to the Department of Oral Medicine were orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. 2. The rate of referrals was 58.51% which implies that more than half of the patients visiting the Department of Oral Medicine were referred. 3. The types of institution which made referrals were analyzed, and as a result, dental clinics made most of the referrals with the rate of 83.23%, while that from medical or oriental medical institutions was 16.78%. 4. Among the patients who visited the Department of Oral Medicine on their own, 30.52% gained the information about the Department of Oral Medicine from internet and mass media, and from neighbors. From the above results, most of the patients visiting the Department of Oral Medicine were found to be referred not only from the field of dentistry but also from the field of medicine. These suggest that Oral Medicine manages patients who are not treatable by general dental practitioners, and medical specialists tend to cooperate with the Department of Oral Medicine to manage diseases associated with Oral Medicine. Therefore, the role of Oral Medicine can be considered to be important as a special field, and the results of this study should be considered when working out a policy of Dental specialist system on demand and supply of residents in the future.

Seventy four patients with soft tissue sarcomas treated by postoperative radiotherapy in the Department of Therapeutic Radiology, Seoul National University Hospital between August 1979 and September 1990 were analyzed. The follow-up Period ranged from 3 to 145 months with a median of 51 months. Liposarcoma and malignant fibrous histiocytoma(MFH) constituted $54\%$ of the cases and the histologic grades of tumors are as follows: grade I, 23 cases; grade II, 17 cases; grade III, 24 cases: unknown grade, 10 cases. The patients were treated by marginal(17 cases), wide(55 cases) or compartmental(2 cases) excision followed by Postoperative radiotherapy. The total radiation doses were 4200-8820 cGy (median 6000 cGy), 180-200 cGy daily. 5 times per week. Of 74 Patients, 35 ultimately failed. The local control was $62.2\%$ at 5 years and cumulative risk of distant metastasis was $22,3\%$ at 5 years. The overall survival and disease free survival were $72.3\%$, and $53.3\%$ at 5 years, respectively. Survival after appearance of metastasis was $15.1\%$ at 3 years. Patients with liposarcoma experienced better local control than those with other histologic type and tumor grade and surgical resection margin significantly correlated with local recurrence, distant metastasis and overall survival on univariate analysis. In conclusion, re-excision is needed for patients with positive surgical resection margin to improve local control and further therapeutic measures using effective chemotherapy should be explored in the hope of improving overall survival.

This study was performed to investigate the characteristics of soft tissue profile of the class III malocclusion and to test the yardstick far differential diagnosis between surgical and orthodontic patients. Initial lateral cephalograms of orthodontic group(30 patients) that have acceptable occlusion and profile by orthodontic treatment alone and surgical group(30 patients) that have favorable occlusion and profile by combined surgical-orthodontic treatment were selected in Ajou university hospital. Powell and Burstone II analysis were made on the tracing. Descriptive, comparative, factor, cluster, and discriminant analysis were carried out with computer program. The results were as followings : 1. Patients who received surgery had a more concave profile and a longer lower facial height than patients who received orthodontic treatment alone. 2. Nasolabial angle, ratio of vertical height, and mentolabial sulcus were significantly different at the 5% level. And facial protuberance, upper lip protuberance, mentocervical angle, nasofrontal angle, nasomental angle, mandibular vertical height, angle between cervix and lower face, ratio of mandibular vertical height divided by cervical depth, ratio of vertical height between upper and lower lip, and maxillary protuberance were significantly different at the 1% level. 3. 8 factors were extracted and factor 2, 3, and 8 showed significant differences by factor analysis. 4. Orthodontic group (25) and surgical group (35) were classified by cluster analysis. 5. Discriminant function was D = 0.079Nasomental angle + 0.081Sn-Gn + 3.343Sn-Gn/C-Gn + 1.734Sn-St/St-Me' -26.460, and cutting score was 0, so we can discriminate that orthodontic group has the score above 0, and surgery group below 0. And 91.7% of original grouped cases were correctly classified.

Background: A retrospective analysis of all cancer patients attending the radiotherapy outpatient department (OPD) of a single unit during the period of January 2005 till December 2006 was conducted to know the geographical distribution and incidence of the most common cancers, their stage of presentation, treatment compliance among the patients and follow-up. Materials and Methods: A total of 4,484 patients were registered in the Institute of Medical Sciences, Banaras Hindu University during the period of January 2005-December 2006; of which 1,975 registered in an individual unit were included for the retrospective analysis. Results: Most of the patients hailed from the various districts of UP and Bihar. Females outnumbered males with a ratio of 1.33:1. Females mostly belonged to the age group of 40-59 years; whilst males were a decade older. Major cancer sites in females were cervix and breast followed by head and neck. Leading cancer sites in males were head and neck, brain, bone, soft tissue and lung. Most of the cases presented in advanced stage of disease (74%). Squamous cell carcinoma was the most common histopathology (56%). A significant proportion of patients defaulted after undergoing preliminary investigations (16%). Only 53.9% of females and 58.5% of males took treatment out of which 68% and 63% completed the prescribed treatment. Compliance with follow-up was poor. Conclusions: The outcome of this study will significantly help us to define region specific strategies needed for cancer management in eastern Uttar Pradesh.

Purpose : A new method of lateral cephalometric analysis for midface, focusing on zygomatic bone, was created in this study, and measured in Korean adults. The purposes of this study are understanding about new approach for midfacial depression, especially zygomatic bone, and using to make adequate diagnosis and treatment plan. Materials and methods : In this study, esthetic Korean adults, 25 males and 25 females who were between $0^{\circ}$ and $4^{\circ}$ in ${\angle}ANB$, and between 62% and 70% in P/A facial height ratio, and had normal overbite and overjet, were used. Orbitale(Or) and Soft tissue orbitale(Or') were used for indicators of anteroposterior position of zygomatic area. And, mean value and standard deviation of linear and angular measurements, and ratio about each linear measurements, were obtained. then, standard deviation diagram - wiggle diagram - was made for visualization of results. Results : Mean values, standard deviations and ranges of 19 measurements were obtained, and among them, 5 linear measurements that had large standard deviation were excluded and the others were used for making standard deviation diagram. In standard deviation diagram, the following results were obtained. 1. If the measurements are located on more left side of mean-value-vertical -line, the potential of midfacial hypoplasia are stronger, especially zygomatic area. 2. If the measurements are located on more right side of mean-value-vertical-line, the potential of midfacial hypoplasia are decreased. Conclusion : This study presented a new method of lateral cephalometric analysis focusing on zygomatic bone in Korean adults. We expect that the results of this study can be used as parameter when clinicians make decisions about diagnosis and treatment plan for rehabilitation of esthetics and function. But, it is necessary to prove its usefulness, and to further evaluate the results.

Objectives : Wiryeong-tang (WRT) is a traditional herbal medicine used to treat kidney-related diseases. However, the anti-inflammatory and anti-gastritis effect of Wiryeong-tang was not well known. Therefore, we experimented to confirmed the anti-inflammatory and anti-gastritis effects of Wiryeong-tang. Methods : The RAW 264.7 cells were pre treated with Wiryeong-tang mix soft extract (WRT-mse; 50, 100 and 200 ㎍/mL) for 1 hrs, and then incubated with lipopolysaccharide (LPS; 500 ng/mL). Cell viability was measured by the MTT method, and nitric oxide (NO) was measured with griess reagent. In addition, pro-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). For anti-gastritis effect in vivo, acute gastritis was induced using 150 mM HCl/60% ethanol used ICR mice. WRT-mse (133 mg/kg) was pre treated for 3 days and then treated with 150 mM HCl/60% ethanol 1 hrs later. Then gastritis was observed and inflammatory cytokines in the gastric tissue was measured. Results : The 8 marker components of the WRT-mse were determined by simultaneous analysis using HPLC. WRT-mse was not toxic and inhibited pro-inflammatory cytokines such as IL-1β, IL-6 and TNF-α at NO production, protein and mRNA levels. Also, it was confirmed that WRT-mse improved bleeding and edema in gastritis, and suppresses inflammatory cytokines. Conclusion : In summary, our results suggest that the treatment of the WRT-mse reduced and improved the 150 mM HCl/60% ethanol induced acute gastritis and the inflammation caused by LPS stimulation in RAW 264.7 cells. Therefore, this study may provide useful drug or clinical evidence for WRT-mse to prevent inflammation.

Objectives : This study will broaden understanding of acupotomy therapy through comparison of side effects and complication which can be caused by the mechanism of treatment, surgical methods, and procedure by acupotomy therapy and epidural neuroplasty. Moreover, through an in-depth analysis of headache affected by two procedures, this research is supposed to find prospective cures for headache after acupotomy therapy. Methods : To compare acupotomy therapy with epidural neuroplasty this research was done using a comparative analysis eight theses about acupotomy therapy since 1995, as well as eleven theses about epidural neuroplasty since 2000. Other theses and data were used as references in the process of comparative analysis. Results : Acupotomy therapy and epidural neuroplasty, new treatments of damaged discs in the spine and stenosis made in 1990s, have the mechanism of treatment in common in that adhesion, a node or scar caused by the soft tissue damage is removed by putting catheter or acupuncture into the lesions. Epidural neuroplasty has additional injection into the lesions, which is different from acupotomy therapy in the process of surgical procedure. There are various reports of positive effects about curative effect in these two treatments. The two procedures may cause various complications. Headache may be a complication after surgery. The headache after acupotomy therapy is characterized as being an ache in the body, which is similar to that of post-dural puncture headache in the outbreaks and symptom. Headache after percutaneous epidural neuroplasty appears in general, which is similar to a headache as a result of the increased pressure of the brain spinal cord regardless of posture. Conclusions : Although they are alike in the mechanism of treatment, surgical methods and side effects, and complication after they are carried out as a result of analyzing theses related to acupotomy therapy and percutaneous epidural neuroplasty, there is a difference in aspects and mechanism of headaches experienced after the procedure.
