We analyzed records at Chonnam university hospital from Sep. 1. 1993 to Aug. 31. 1996 to assess clinical significance of the foreign body in the gastrointestinal tract. There were 133 episodes consisting of 79 pediatric and 54 adult patients as possible to review. In the pediatric patients, the coin was the most common cause of foreign body ingestion, while adult patients were usually caused by bones and meat. We removed foreign bodies in the oral cavity and oropharynx in 12 cases using direct laryngopharyngoscpy and forcep. Endoscopy was performed successfully in 47 of 51 patients in which was attempted; there were two complications composed of an aspiration pneumonia and a mediastinitis due to esophageal perforation. There were spontaneous passage of foreign bodies in 48 cases. We observed complications in 6 cases in which 4 cases needed operations due to complications. Foreign bodies which pass into the stomach can be observed for development of complications, as 94% of foreign bodies which reach the stomach spontaneously pass. Only 4 patients required interventions, which was done without mortality.

Prevertebral soft tissue swelling of cervical spine lateral radiogram is well known as an indirect evidence of occult cervical spine injury. But the clinical and statistical value of it has been of debate. We tried to analyse the value of cervical prevertebral soft tissue width as a screening test for cervical spine injury by comparison of two categorized study groups; the control group, traumatized patients without cervical spine injury and the injury and the injury group, traumatized patients with bony cervical injury. The injury group consisted of patients admitted between September 1993 and December 1994 with an ED diagnosis of bony cervical injury. The control group consisted of patients admitted between January 1994 and June 1994 who received cervical spine lateral radiograph because of suspicion of cervical spine injury or as a routine check. In both group, we sampled the patients who received cervical spine lateral rediograph within 24 hours after injury and excluded the patients less than 15 years old and more than 65 years old, In the control group, we confirmed the patients had no problem in cervical spine of follow-up. 101 control patients and 68 injury patients were identified. The injury group was further divided into two subgroups: those with injuries at C1-C3 to the upper injury subgroup and those with injuries at C4-C7 to the lower injury sub group. The prevertebral soft tissue widths of injury group were larger than of control group at C2(mean 6.1mm versus 4.5mm) and also at C6(mean 13.4mm versus 11.2mm). Especially upper injury subgroup had quite large value of C2 prevertebral soft tissue width(mean 14.1mm). Nevertheless, both in C2 and C6, there is no cutoff value with acceptable sensitivity and specificity as a screening test. But the 7mm at C2 and 14mm at C6 had high specificity(90%) and were thought to be a good radiologic indicators of further evaluation.

Seong-Hyeon Heo,Hae-Beom Lee,Jae Min Jeong,Young-Jin Jeon,Dae-Hyun Kim,Seong Mok Jeong,Yoon-Ho Roh 한국임상수의학회 2022 한국임상수의학회지 Vol.39 No.5

Multilobular osteochondrosarcoma (MLO) reportedly has a good prognosis after complete resection. This study reports the successful treatment of MLO in two dogs using 3-dimensional (3D) printing technology. A nine-year- old castrated male Maltese (Case 1) and a five-year-old castrated male poodle (Case 2) both presented with a mass in the skull. Diagnostic imaging revealed a cranial mass arising from the cranio-orbital and parieto-occipital bones. The masses were resected using 3D-printed osteotomy guides, and the resulting de- fects were reconstructed using 3D-printed patient-specific implants. Histopatho- logical results confirmed the resection of MLOs with clean margins. Patients routinely recover from surgery without complications. To date, the two patients remain alive without clinical signs of tumor recurrence at 20 and 12 months postoperatively, respectively. In the management of MLO in dogs, 3D printing technology can allow accurate tumor resection, reduced surgical time, and suc- cessful reconstruction of large defects.

Purpose - Food consumption in Korea has changed in paradigm as it has grown qualitatively in the past in quantitative shortages. Consumer food consumption patterns are rapidly changing due to changes in economic, social and population conditions, scientific and technological development, climate change, and market opening. At the same time, there is a need to actively respond to these changes in terms of the food industry, market, and government policy. The purpose of this study is to examine the changes and characteristics of food consumption expenditure of Korean consumers in-depth and depth in order to provide implications for agriculture, food market and policymakers. Research design, data, and methodology – We analyzed various food consumption changes from the 1980s to 2015 through Household Income and Expenditure Survey raw data from MDIS(Microdata Integrated Service) of Statistics Korea. and conducted the age effect, generation effect, and year effect by cohort analysis. We also conducted comparisons with OECD countries on several indicators. Results - Food consumption spending was slow, and there was no significant change in home consumption, while eating out consumption increased about 20 times in 2015 compared to 1980. Income, age, residential area, number of household members showed significant changes in food consumption. According to the cohort analysis, the changes in the food consumption structure are largely due to age effect, and the year, age, and generation effects are different for each food item. Conclusions - Food consumption has a significant impact on not only the nutritional status of consumers but ultimately the public health. Therefore, they should be regarded as a strategic policy area of central government rather than a matter of size and change of food consumption expenditure.

STATEMENT OF PROBLEM: While patient-centered outcomes are usually not reported, these may represent major aspects of the implant success for the patient. Use of a well-designed patient survey form can be an invaluable asset to the implant practitioners. PURPOSE: The objective of this study was to investigate patient satisfaction after implant therapy by means of a questionnaire. MATERIAL AND METHODS: South Korean patients (n = 100), who visited the dental examination center of Soon Chun Hyang university hospital, were asked to fill out the satisfaction questionnaire regarding aspects of cost, comfort, esthetics, chewing, gingival health, food impaction, phonetic aspect, screw loosening, and general satisfaction. Responses to statements were given on the Likert response scale. Four experimental groups of patients were distinguished with various location ($A_1,\;A_2,\;A_3$), year ($B_1,\;B_2,\;B_3$), number of implant replacements ($C_1,\;C_2,\;C_3$), and treatment cost ($D_1,\;D_2,\;D_3$). The reliability of the response scales was measured by calculation of its internal consistency, expressed as Cronbach's ${\alpha}$. The scales were distinguished by means of factor analysis method. Possible differences in scale scores among the groups were assessed by One-way ANOVA (${\alpha}$= 0.05). RESULTS: Patients responded to most of the statements with high satisfaction. But the mean scale score of statement about cost was low. After the verification of internal consistency and factor analysis, five components, e.g. general satisfaction, comfort, chewing efficiency, esthetics, and phonetic aspect were grouped together. These components could be explained with common meaning and the first factor was named as 'general satisfaction'. Differences in patient satisfaction on the scale with esthetics were present between patients who have been wearing the implant prosthesis less than three years and those more than seven years ($B_1<B_3$). CONCLUSION: The patients were generally satisfied with the outcome of implant treatment. But the patients' major complaint was high cost and while the statistically significant difference was not shown, the satisfaction scale about food impaction and esthetics was low. So the continuing efforts to make improvements about these problems are needed for the implant practitioners.

Surgery is a treatment that can achieve a very dramatic effect, but any surgery can lead to complications. Therefore, in order to perform safe operation, proper evaluation of the lesion should be performed before surgery and it is necessary to predict complications that may occur in each operation and prepare for preventing it. In general, complications that can occur after surgery include persistent bleeding, hematoma, secondary infection, and necrosis of the surgical site. We report three cases in which complications occurred after the residents performed the surgry. These cases are examples of common complications that we may encounter during surgery and we will look at what we could do to prevent complications.

Trichoepithelioma (TE) is a benign adnexal neoplasm that originates from hair follicle and malignant transformation is very rare. TE is classified as solitary TE, multiple familial TE, and desmoplastic TE. There are some reports of multiple familial TE transformed to malignant tumor such as basal cell carcinoma (BCC) and trichoblastic carcinoma. A 82-year-old man presented with asymptomatic skin colored papules and nodules on the central face for 10 years. The patient was not aware of his TE family history. The lesions initially appeared in skin color, but some lesions turned black. Clinically, TE was suspected and punch biopsy was performed from nodules on the left nose alar and both inner canthi which turned black. Histopathologic findings were consistent with BCC. We performed Mohs micrographic surgery for BCC lesions. Histopathologic examination of left nose alar showed dermal tumor composed of atypical basaloid cell with peritumoral cleft and epidermal connection on the central portion and well-circumscribed dermal tumor composed of basaloid cell with many horn cysts on the peripheral portion. Clinical features and histologic findings demonstrated his BCC arising from multiple TE and the patient is under observation without recurrence until 11 months later.

Malignant melanoma (MM) is a malignancy of melanocytes, located mainly in the skin, but also found in the ears, gastrointestinal tract, eyes, oral and genital mucosa. The risk factors for MM include ultraviolet radiation exposure, phenotypic traits such as large congenital nevus, numerous typical nevi and more than one atypical nevus, history of prior MM, genetic factors, and immune suppression. Cancer associated with burn scar can develop more than 30 years after burn. The most common cancer is squamous cell carcinoma and MM is extremely rare. A 55-year-old man presented with tender erythematous and black colored nodule and patches on the burn scar of back. We performed incisional biopsy on the nodule and punch biopsy on the black patch around the nodule. Histopathological finding of nodule demonstrated tumor composed with HMB45-positive atypical melanocytes with pagetoid spreading and invasion of subcutaneous layer. Histopathological finding of black patch showed lentiginous proliferation of atypical melanocytes in the epidermis. We diagnosed him with MM and melanoma in situ. Chest computed tomography revealed enlarged lymph nodes in right axilla. He underwent wide excision of the primary lesion and sentinel lymph node biopsy and 6 lymph nodes were identified with metastasis. Next generation sequencing was performed and known mutations of MM were not found. The patient is under observation without recurrence until 10 weeks later.
