Pharyngeal Closure Reinforced With Sternohyoid and Omohyoid Muscle After Total Laryngectomy / 대한이비인후과학회지

Pharyngocutaneous fistula occurring after total laryngectomy is a bothersome complication as it can even cause a massive bleeding due to carotid artery rupture. Preoperative radiation, extensive diseases which need flap reconstruction, low albumin or hemoglobin level, history of smoking, or underlying diseases have been domestically reported to have a relationship with the condition. To reduce this complication, simultaneous coverage for the pharyngeal closure has been developed using flaps, such as the pectoralis major muscle, the radial forearm or the anterolateral thigh, which are distant from the radiation field. However, these methods need additional surgical techniques and times. Another method advocated is pharyngeal reinforcement using flaps that can be easily obtained from the same surgical field, such as the sternocleidomastoid or the infrahyoid muscle or the acellular dermal graft with relative significances. Here we suggest reinforcement of pharyngeal closure after total laryngectomy using the sternohyoid and omohyoid muscle flaps.

Guideline for the Surgical Management of Locally Invasive Differentiated Thyroid Cancer From the Korean Society of Head and Neck Surgery

The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.

Dysphagia Caused by Giant Granuloma Arising from the Oropharyngeal Posterior Wall

Granuloma is an uncommon benign disease that develops in the process of wound healing. Pharyngeal or laryngeal granuloma can be associated with gastric reflux, mechanical injury or trauma including intubation, voice abuse, or foreign body. 50-year-old female was transferred to our institute with a huge mass occupying the upper aerodigestive tract causing dysphagia. The patient has been suffering from a brain hemorrhage for several months and was kept in bed due to the quadriplegia with stuporous mental status, and was tracheotomized. On examination, the whole oropharynx and hypopharynx was covered by a smooth-surfaced soft big diffuse granular mass, which extended down to the upper trachea through the larynx. The huge granuloma was successfully removed with surgery and was found to have a pedunculating stalk on the oropharyngeal posterior wall with a small mucosal defect, suggestive of the origin of the mass. The defect was closed primarily after the cauterization. The patient is now followed up regularly without any recurrence of the disease.

Development of Sound Field Audiometry System for Small Audiometric Booths and Comparison of Its Equivalence With Traditional System

Objectives@#. Sound field (SF) audiometry tests are usually conducted in audiometric booths measuring greater than 2×2 m in size. However, most private ENT clinics carry about 1×1-m-sized audiometric booths, making SF audiometry testing difficult to perform. The aims of this study were to develop an SF audiometry system for use in smaller audiometric booths and compare its performance with traditional system. @*Methods@#. The newly developed SF audiometry system can yield an SF signal at a distance of about 30 cm from the subject’s ears. Its height can be adjusted according to the subject’s head height. We compared SF hearing results between the new SF system and the traditional SF audiometry system in 20 adults with normal hearing (40 ears) and 24 adults with impaired hearing levels (38 ears) who wore hearing aids. Comparative parameters included warble tone audiometry threshold, a speech reception threshold (SRT), and a speech discrimination score (SDS). For statistical analysis, paired t-test was used. The equivalence of both SF systems was tested using two one-sided test (TOST) with a margin of 5 dB (normal hearing participants) and 10 dB (hearing aids wearing participants). @*Results@#. Among participants with normal hearing, warble tone hearing thresholds of 0.5, 1, 2, and 4 kHz, average values of these four frequencies, and SRT were similar between the two systems (all P>0.05). Participants with hearing aids showed similar warble tone threshold and SRT (P>0.05) in both systems except for threshold of 4 kHz (P=0.033). SDS was significantly higher in the newly developed system (P<0.05). TOST results showed equivalent SF audiometry results using either system. @*Conclusion@#. Audiometric results of the newly developed SF audiometry system were equivalent to those of a traditional system. Therefore, the small SF audiometry system can be used at small audiometric booths present in most private ENT clinics.

The Relationship between Oral Health and Stroke in Adults Based on the 6th (2015) Korea National Health and Nutrition Examination Survey / 치위생과학회지

Stroke is the second cause of death worldwide, although the survival period is increasing after the occurrence of stroke, severe physical disability is caused with aftereffect. Oral inflammation is not limited to the oral cavity, it can cause malignant changes in other tissues and organs. In previous studies, we confirmed the relationship between tooth loss and stroke due to periodontal inflammation. The purpose of this study was to investigate the relationship between oral health and stroke such as oral hygiene behavior, tooth loss and periodontal disease among Korean adults over 40 years of age. This study was analyzed using the 6th Korea National Health and Nutrition Examination Survey (KNHANES) data. A total of 3,389 adults over 40 years of age were analyzed as final subjects. Socioeconomic statuses and oral health status was analyzed using a complex sample analysis technique. Logistic regression was used to analyze the relationship of oral health and stroke, and 95% confidence intervals were computed using SPSS. When the prevalence of stroke according to oral hygiene behavior was checked, the prevalence of strokes was lower in subjects who had a lot of brushings per day and subjects who used oral hygiene products (p 0.05). Loss of teeth was found to be associated with the risk factor of stroke. Therefore, loss of teeth due to periodontal disease is an additional issue that should be considered as a risk factor for stroke.

The primary objective of this study was to develop an optimal composite recipe for ginger extract candy with Salicornia herbacea L., for consumption during the first trimester of pregnancy. The secondary objective was to examine quality characteristics of the candy. The physical and mechanical properties and sensory properties for pregnant women in were measured, and these values were applied to mathematical models. Time of stirring water solution, saltiness, pH, and redness of the candy increased as concentrations of ginger juice did, but variations in pH were not significant. The hardness values of the candy ranged from 3,063.90 to 5,681.65 dyne/cm³. The average values of sweetness and time stirring the water solution were 5.36% and 14.1 minutes, respectively. However, hardness and sweetness stirring water solution were not significant. The range of sensory values of color (P < 0.01), flavor (P < 0.05), sweetness, saltiness, spiciness, and overall quality (P < 0.05) ranged from were 3.73~5.32, 4.05~5.05, 3.67~5.14, 3.59~5.09, 3.55~5.15, and 3.32~5.45, respectively. Results suggest that ginger extract candy with Salicornia herbacea L. should be comprised of 7.37 g of ginger juice and 1.77 g of salt. Consequently, it could be a functional candy for pregnant women.

Development of Cookies with Brewer's Yeast and Beans to Improve Skin Health of Lactating Women

The purpose of this research was to provide basic information for cookies made with black soybeans, chick peas, lentils, oatmeal, and brewer's yeast and to establish the optimum formula for the development of low glycemic index (GI) cookies with high biotin content for lactating women. This study was performed to determine the optimal composite recipe of oatmeal cookies with two different concentrations levels of bean powder (black soybeans, chick peas, lentils) and brewer's yeast using a central composite design. In addition, the mixing conditions of oatmeal cookies were optimized using response surface methodology of sensory evaluation and mechanical and physicochemical analysis. As a result, mechanical and physicochemical analyses showed significant values for lightness, redness, yellowness, hardness, and water content (P < 0.05), while sensory evaluation showed significant values for flavor, taste, crispness, and overall acceptability (P < 0.05). The optimal sensory combination was suggested to be 3.73 g of bean powder and 1.59 g of brewer's yeast. Considering all outcomes obtained throughout the experiments, brewer's yeast, black soybeans, chick peas, lentils, and oatmeal are suitable ingredients for increasing functionality and consumer acceptability of cookies. In addition, these results are expected to be useful in producing cookies of optimal quality, contributing to the development of various nutritious foods, and improving the food industry for lactating women.

Relationship between stress and subjective oral dryness in the elderly in a rural region: a pilot study / 대한구강보건학회지

OBJECTIVES: Stress is a psychological reaction to stimuli such as anxiety or threat felt by a person either physically or mentally when placed in a difficult situation. Although a relationship between stress and dry mouth has been reported, it remains understudied. The purpose of this study was to investigate the association between stress and subjective dry mouth among the elderly living in a rural region. METHODS: A total of 214 people aged ≥60 years living in a rural area were recruited with an informed consent for a cross-sectional analysis. Information about stress and subjective dry mouth was obtained by an interview survey with a constructed questionnaire. Data on other potential confounding factors (including oral factors) such as socio-demographic data, health-related behaviors, the number of remaining teeth, and subjective chewing ability were also gathered at the same time. Logistic regression models were used to analyze the relationship of stress and dry mouth using SPSS. RESULTS: The Crude odds ratio (OR) of stress awareness affecting subjective dry mouth was 2.59 (95% confidence interval: 1.43–4.68). After adjusting for sex, education, income, smoking, and alcohol intake, the adjusted OR was 2.52 (95% confidence interval: 1.30–4.87) which was statistically significant. CONCLUSIONS: Elderly people who were stressed had an approximately 2-fold increase in experiencing subjective dry mouth when compared to their stress-free counterparts.

Evaluation of the Menus of Senior Welfare Centers for Home-bound Elderly

This study examined the characteristics of the foodservice menu items offered at senior welfare centers to provide information on Korean senior menu development. A total of 514 lunch menu items were collected from 27 senior welfare centers in April, July, October and January. The most frequently served staple foods, soups, and side dishes were multi-grain rice, seaweed soup, Bulgogi, Kimchi, and liquid yogurt. The proportions of carbohydrate, protein, and lipids of total energy serving of senior welfare centers were 59.8%: 16.7%: and 22.8%, respectively. The nutrients served at less than 40% of the Recommended Nutrient Intake (RNI) and Adequate Intake (AI) of Dietary Reference Intakes for Koreans (KDRIs) were chloride (1.0%), vitamin D (1.3%), biotin (1.7%), magnessium (4.5%), Iodine (7.5%), pantothenic acid (8.0%), vitamin E (12.5%), vitamin B6 (20.0~21.4%), vitamin K (21.1~24.3%), and water (35.7~39.7%). The nutrients served in excess of the daily intake goal and RNI were iron (98.9~127.1%), sodium (104.9%), and copper (1,100.0%).

Intractable Methicillin-Resistant Staphylococcus Aureus Otorrhea with Silicone Impression in the Middle Ear

We report a case of methicillin-resistant Staphylococcus aureus (MRSA) otorrhea with impression material of hearing aid in the middle ear. The patient had chronic otitis media in the right ear with sensorineural hearing loss in both ears. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. Several days after hearing aid fitting, the patient had severe otalgia, intractable otorrhea, aggravated hearing loss, and dizziness. The pus culture and sensitivity test revealed MRSA. After topical treatment using diluted vinegar irrigation and ototopical vancomycin solution, intractable otorrhea was controlled. The infected silicone impression was removed by canal wall-up mastoidectomy, and hearing was saved. We present here a review of the literature regarding silicone impression in the middle ear after hearing aid mold fitting.

Clinical Characteristics and Hearing Results of Sudden Sensorineural Hearing Loss in Child / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Sudden sensorineural hearing loss (SSNHL) in children can occur just as can in adults; in fact, it may last throughout the entire life of a child, affecting the individual much more than when it does to an adult. As there are only a few studies that have focused on SSNHL in childhood, we investigated the clinical characteristics and hearing outcomes of pediatric SSNHL. SUBJECTS AND METHOD: A retrospective review of patients from November 2005 to May 2014 was carried out. Thirty nine patients under the age 15, who were hospitalized due to SSNHL were enrolled. Of these patients, 226 patients over the age of 15 were collected as a comparison group. Age, sex, underlying disease, site of hearing loss and duration from the onset to treatment were analyzed. We evaluated the overall recovery rate as well as the recovery rate according to accompanying diseases. RESULTS: Recovery rates were comparable between the pediatric and the adult group. Overall recovery rate was 60% in the pediatric group. Unlike for the adult group, dizziness and tinnitus were not a prognostic factor in the pediatric group. Pediatric patients showed similar overall recovery, whether the treatment initiation was under 7 days or more. Recurrence was seen in 3 patients, of which 2 showed complete recovery. CONCLUSION: The recovery rate for SSNHL was similar for the pediatric and the adult groups. A higher recurrence rate may alert clinicians to be aware of hearing changes after the recovery in pediatric patients.

The relationship between the number of remaining teeth and senile dementia: A pilot study / 대한구강보건학회지

OBJECTIVES: Recently, studies aiming to improve the quality of life of the elderly have become more common. In the aging population, oral health is an important consideration for overall good systemic health. Oral health is closely related to general health and should not be ignored. The purpose of this study was to determine whether there are associations between the mastication level and number of remaining teeth and the cognitive function. These associations were investigated using the Mini-Mental State Examination (MMSE) score and the results of oral examinations in elderly individuals. METHODS: Participants who were aged over 60 years and living in Daegu city underwent oral examination for assessing their oral condition; their cognitive function was evaluated using the MMSE. The collected data were analyzed using the chi-square test, t-test, and logistic regression in SPSS. Logistic regression was used to analyze the relationship between the MMSE score and the number of remaining teeth, and the 95% confidence intervals were computed. RESULTS: Although a significant relationship was found between the number of remaining teeth and the MMSE score, the differences were not large. The odds ratio (OR) when the number of remaining teeth was 0-10 was 3.02 (95% confidence interval: 1.200-7.581). CONCLUSIONS: This study showed a slight but significant relationship between the MMSE score and the number of remaining teeth in elderly individuals.

Relation between rheumatoid arthritis and periodontal diseases: Using the Fifth Korea National Health and Nutrition Examination Survey / 대한구강보건학회지

OBJECTIVES: Rheumatoid arthritis (RA) has been associated with systemic diseases, such as periodontal diseases. Periodontal diseases and RA appear to share many pathologic features. The etiology of the two diseases may differ, but they share similar pathological characteristics. Therefore, the aim of this study was to evaluate the correlation between RA and periodontal diseases. METHODS: Data from the Fifth Korea National Health and Nutrition Examination Survey (KNHNES) were used to analyze periodontal status according to the presence of RA. Demographics and oral behaviors were analyzed using the complex chi-square test to compare participants with RA with those without RA. Complex logistic regression was used to analyze relationships of periodontal diseases with RA and other covariates. RESULTS: The odds ratio for periodontal diseases was 1.91 (95% confidence interval: 1.05-3.48) in participants with RA compared with participants without RA. CONCLUSIONS: The results of this study provide evidence of a significant association between periodontal diseases and RA.

Quality Characteristics of Yanggaeng Supplemented with Sanghwang Mushroom (Phellinus linteus) Mycelia

The principal objective of this study was to examine the quality characteristics of yanggaeng supplemented with powder derived from Sanghwang mushroom (Phellinus linteus) mycelia. We analyzed the potential of utilizing Phellinus linteus mycelia as a functional food material by estimating total polyphenol and flavonoid contents, electron-donating abilities, as well as antioxidative activities of the water and ethanol extracts of Sanghwang mushroom mycelia. The total phenol and flavonoid contents of ethanol extracts from Phellinus linteus mycelia were 0.69 mg/ml and 0.16 mg/ml, respectively, while the contents from the water extract of Phellinus linteus mycelia were 0.66 mg/ml and 0.22 mg/ml, respectively. The electron-donating abilities of ethanol and water extracts from Phellinus linteus mycelia were 88.64 and 90.29%, respectively. The ABTS radical scavenging activities of ethanol and water extracts from Phellinus linteus mycelia were 89.74 and 71.35%, respectively. In terms of color values, as the level of powder increased, the value of L (lightness) decreased, whereas those of a (redness) and b (yellowness) increased. In regard to the mechanical properties of the samples, we noted significant differences in hardness, springiness, chewiness, and gumminess (P<0.05). The results of the sensory evaluation showed that the score from SHM (Sanghwang mushroom mycelia) with 4% powder was significantly higher than other samples in terms of sweetness, color, taste, texture and overall quality (P<0.05). Taken together, the recommended level of Phellinus linteus mycelia powder in yanggaeng is 4% for optimal sensory characteristics.

The comparison of the characteristics of Streptococcus mutans isolated from caries free and high caries children / 대한구강보건학회지

OBJECTIVES: Streptococcus mutans (S. mutans) is the major causative bacteria in human dental decay. Most findings have shown that S. mutans are widely distributed in populations with moderate to high caries prevalence. However, observations have shown that S. mutans are also frequent in populations with low caries prevalence, as well. This study evaluated the relationship between the dental caries experience and the virulence factors of S. mutans, which are isolated from caries-free and high-caries individuals. METHODS: The dental caries experience states with the WHO diagnostic criteria, which were examined for children (aged 8 to 9 years) from two schools that are located in Daegu, Korea. A total of 22 caries-free (dfs+DFS=0) and 12 high-caries (dfs+DFS> or =14, ds+DS> or =9) were selected for this study. Dental plaque samples were obtained and incubated in MSB plate to culture S. mutans. After isolation and identification, the level of S. mutans, attachment ability, and streomicroscopy were analyzed. RESULTS: The S. mutans counts and attachment ability were higher in the high-caries group than in the caries-free group (P<0.05). In addition, the colonies isolated from the caries-free group adhered less strongly to the Mitis Salivarius Bacitracin agar. There were less of the sticky substances from the surface of the S. mutans colonies in the caries-free group. CONCLUSIONS: These results indicate that caries activity affected by the virulence not only the number of S. mutans.

Nutrition Knowledge and Need for a Dietary Education Program among Marriage Immigrant Women in Gyeongbuk Region

The purpose of this study was to provide basic materials and assistance for developing a nutritional education program targeting marriage immigrant women, and it was carried out on 86 female marriage immigrants living in the Gyeongbuk region. An average age of the female marriage immigrants who participated in this survey were 28.6 years, and their home countries were the Philippines (32.6%), Vietnam (29.1%), and so on. Exactly 59.3% of subjects had been married for 1~5 years, and 40.7% of the subjects had an education status of less than middle school graduation. The majority of them (65.1%) had one more children, and 51.2% of subjects were a part of a nuclear-family, with the husband's age between 40~49 years old (58.1%). Concern for nutrition label was significantly different according to number of children (P10 years than <1 year (P<0.01), and education level of college & university graduation than less than middle school (P<0.05). Sixty percent of the women surveyed participated in the education program of 'Korean language' as they were in their country, and the most preferred education program was 'Korean dietary life and culture' (39.5%). Regarding participation and educational method, the majority of subjects responded that they wanted to learn nutritional education in a cooking academy or school (52.9%) and public health center (34.1%).

Quality Characteristics of Mungbeanmook Added with Gugija (Lycii fructus) Infusion

The principal objective of this study was to evaluate the quality characteristics of mungbeanmook prepared with five different levels (0, 5, 10, 15, and 20%) of Gugija (Lycii fructus) infusion. We analyzed Hunter's color values, pH, texture characteristics, and perfomed sensory evaluation of mungbeanmook prepared with Gugija infusion. The pH levels of mungbeanmook ranged between 5.45 and 6.12 and did not show significant differences. As Gugija infusion concentration increased, the color lightness "L" value decreased, whereas redness color "a" value and yellowness color "b" values increased (P<0.05). With regard to mechanical texture properties of the mungbeanmook samples, as the Gugija infusion concentration increased, the scores of hardness, chewiness, and gumminess all significantly decreased (P<0.05) whereas there were no significant differences in springiness or cohesiveness. The results of the sensory evaluation showed that the score of the LFLT10 sample (10% Gugija infusion) was significantly higher than those of others in terms of taste, color, flavor, texture, and overall quality (P<0.05). Taken together, the recommended optimum level of Gugija infusion in mungbeanmook is 10% for sensory evaluation. Gugija infusion can be a useful approach to improving quality of mungbeenmook as a functional food.

A Study on the Intakes and Perceptions of Convenient Breakfast / 대한지역사회영양학회지

The purpose of this study was to investigate the intakes and perceptions of convenient breakfast related to age and family type. The survey included 545 men and women living in Seoul from June to July. Questionnaire items covered their age, gender, family types, breakfast intakes and preference for convenient breakfast menu. As a result, there were significant differences in the number of breakfast intakes per week according to family types; large families recorded the highest frequency in "I have breakfast everyday" and the couple-only families and nuclear families scored relatively high numbers. In terms of the type of breakfast, the first choice was "rice and side dishes" across all the age groups (69.3%). There were differences in the preference of convenient breakfast in "bread", "cereal", "rice cake", "sunsik", and "rice gruel" by different age. The teens exhibited the highest preference of bread (5.63), and cereal (5.53) for breakfast; those who were in their fifties for rice cake (5.42). Both forties and fifties showed the higher preference of sunsik (4.58, 4.76) and rice gruel (5.89, 5.77) than other age groups. As for the preference for convenient breakfast according to family types, single person families displayed the highest preference of bread (5.42) and cereal (5.75). Couple families showed higher preference of rice gruel (5.82) than other family groups. The preference level for "rice cake" was similar among all the family types. As a result, it is suggested that the development of various breakfast menus considering age groups and family types is needed so that modern people can enjoy breakfast in terms of quality and quantity in their busy daily life.

Consumption and Satisfaction Evaluation of Takju among Consumers Ages 20 to 29

The purpose of this research was to investigate consumption and satisfaction of Takju (Makgeolli) among consumers ages 20 to 29 living in Seoul and Gyeonggi province. It was found that 86.2% of the respondents drank Takju once or twice a month, and the high satisfaction group drank Takju with a frequency of 8 times a month (P<0.01). Respondents selected market (44.4%) and restaurants (34.9%) as the most common place of purchase, whereas pub (42.2%) and Takju bar (32.8%) were the drinking places selected. Regarding the preferred ingredients, respondents liked pear the most followed by Lycium chinense, corn, pine nuts, ginseng, and citrus fruit. The most compatible foods with Takju were identified as Buchimgae (Jeon) (97.4%), Kimchi (45.6%), Bokkeum (36.4%), Namul & Muchim (25.0%), and Jjim (21.5%). Pajeon was mentioned as the most compatible food with Takju, followed by Bulgogi, Gamjatang, Agwijjim, Dubukimchibokkeum, and Ojingeotwigim. Regarding consumers' satisfaction of Takju, taste was the most highly valued, with color, price, alcohol content, function, flavor, diversity of raw materials, and accuracy of label also highly considered. Further, to formulate a plan to encourage consumption of Takju, the high satisfaction group decided that promotion of local festivals and events related to Takju, standardization of quality, creation of brands, expansion of distribution network, and organization of relevant departments are the most important compared to other items (P<0.05).
