This study tried to derive implications by analyzing the literature related to food psychology to understand the psychological and emotional influence of food. The results of an exploratory study on food psychology are as follows. First, it was found that the perception of taste is related to an individual's state of mind. Second, as the theories for understanding the psychological aspects of food intake, the eating inhibition theory, the emotion regulation theory, and the escape model for binge eating based on the narcissistic theory were confirmed. Third, it was found that tools that can measure symptoms related to binge eating occupy a large portion of food-related diagnostic tools. Fourth, research on food-related psychological disorders was conducted on food cravings, binge eating disorder, bulimia nervosa, eating inhibition, and healthy food obsession. Fifth, it was found that studies related to the treatment of food-related psychological disorders were focused on the cognitive behavioral therapy approach. This study will serve as a basis for understanding and intervening in the emotional impact of food and psychological problems related to food.

In 1923 Pierre-Robin first described the triad of micrognathia, glossptosis and high-arched or cleft palate. Respiratory distress is not an uncommon occurrence and requires prompt and appropriate treatment. The syndrome occurs once in approximately 50,000 births. Although the etiology of the syndrome is obscure, it is known that the syndrome probably results from a primary deficiency early in fetal life of mandibular development. The symptoms of airway obstruction develop as the base of the tongue falls posteriorly and approximates the posterior pharyngeal wall because of micrognathia, and is aggravated when the infant is in the supine position. The problems of mild airway obstruction can be solved by keeping the infant in the prone position. In case there are feeding difficulties, prompt glossopexy should be preformed as airway is aggravated, but tracheostomy is best avoided. There is some forms of glossopexy including Douglas operation, the insertion of Kirschner wire and Duhamel suture. We identified micrognathia, glossoptosis and high-arched palate in a 2-month-old infant who was brought to our hospital with complaints of dyspnea and feeding difficulties, and we reports this case, since we think this infant whom we observe after tracheostomy because we found Duhamel suture could not relieve the symptoms of airway obstruction as Pierre-Robin syndrome.

Pyrifluquinazon is known to act as a feeding inhibitor in several insect species. In this study, we investigated the effect of pyrifluquinazon on the whiteflies, Trialeurodes vaporariorum and Bemisia tabaci. Pyrifluquinazon showed high insecticidal activity (> 90%) against adult T. vaporariorum and B. tabaci at 12.5 ppm to 50 ppm. However, there was no effect on eggs and nymphs of both species. Pyrifluquinazon showed low insecticidal activity in root and foliar uptake. Control efficacy of pyrifluquinazon was above 90% at 5 days after treatment. In order to investigate the behavioral response of the whiteflies initiated by application of pyrifluquinazon, we tested the contact toxicity and ingestion toxicity. After 1 h of contact, whitefly drop, wing convulsion, and paralysis were observed. Similar phenomenon of whitefly population was observed in test of ingestion toxicity after 3 h. In the choice test, pyrifluquinazon showed repellent activity against both species. These results suggest that pyrifluquinazon cause behavioral disorder rather than direct inhibition of feeding.

Pierre Robin syndrome (PRS) is characterized by the triad of congenital mandibular hypoplasia, glossoptosis and cleft palate. Infant PRS patients are frequently suffering from upper airway obstruction, gastroesophageal reflux and growth retardation caused by above mentioned problems. We report a dental caries treatment of 3-year old girl with Pierre Robin syndrome with multiple caries. The cause of multiple caries was mainly presumed as patient's eating habit caused by her general condition. She had some feeding problems and had history of gastric tube. She was still using milk bottle and took more than an hour to finish a meal. The treatment was performed under general anesthesia considering patient's condition; mild autism, poor cooperation and respiratory problem due to micrognathia. Severely affected upper incisors were treated with pulp treatment and restored with zirconia crown for esthetic purpose. Lower incisors were treated with pulp treatment and restored with composite resin. Upper right first primary molar was restored with stainless steel crown and other primary molars were treated with composite resin. There were no postoperative complications. According to her parents, the patient's compliance to oral hygiene management was greatly improved after the treatment since she was very pleased with the esthetic result and highly motivated by her looks. The treatment without sedation or general anesthesia would be possible once the airway is improved as the mandible grows.

Prader-will syndrome (PWS) is a genetic disorder displayed with short stature and behavioral problems. The major manifestation is hyperphagia and obesity but there is no known effective drug that can solve this problem. This article presents a case report of a 3-year 9-month old girl affected with PWS syndrome treated under general anesthesia due to lack of cooperation and multiple caries. The dentist should work as a member of the multidisciplinary medical team. Careful long term follow up is required to prevent dental caries and periodontal diseases as well as maintain good oral hygiene. A strict diet control should also be encouraged.

Objective: The authors would like to find the relationship between zolpidem and nocturnal eating episodes in diverse psychiatric patients. Method: We evaluated case series of 6 patients who showed nocturnal eating episodes after takine zolpidem. Results: We have experienced 6 cases who showed nocturnal eating behavior after taking zolpidem. They included 3 patients with schizoprenia, a patient with major depressive disorder, a patient with PTSD and a patient with bipolra I disorder. With reducing or discontiuation of zolpidem, their nocturanl eating resolved. Conclusion: This finding strongly suggests the relationship between zolpidem and the nocturnal eating episode. Physicians should be aware that zolpidem might induce nocturnal eating behaviors.

There is tremendous variability in the ways patients present with taste problems. Because of complex and multifactorial etiological background, it is not simple to evaluate patients with taste disorders. Accurate assessment of patients' status by prudent, thorough history taking and symptom analysis is the most essential for exact diagnosis of taste disorders. The aim of this study was to investigate the clinical characteristics of patients with taste problems as a primary complaint. Consecutive series of 50 patients (12 males and 38 females, mean age $53.6\;{\pm}\;14.7$ years) were included for the present study. All subjects were requested to complete a comprehensive questionnaire. Clinical evaluation procedures included oral examination, interview, questionnaire analysis, panoramic radiography, blood test and measurement of salivary flow rate. The obtained results were as follows: 1. Among the patients, 36 patients (72%) complained of oral mucosal pain or burning sensation. Of these patients, 18 patients (36%) were diagnosed as burning mouth syndrome. 2. Nineteen patients (38%) complained of subjective oral dryness. The flow rate of unstimulated whole saliva was less than 0.1 mL/min in 14 patients (28%) and 17 (34%) had a stimulated whole salivary flow rate of less than 0.5 mL/min. 3. Among the types of taste disorders, hypogeusia, the most frequently reported, was found in 25 patients (50%), dysgeusia in 18 patients (36%), phantogeusia in 15 patients (30%), hypergeusia in 10 patients (20%), and ageusia in 5 patients (10%). Nineteen patients (38%) reported more than one type of taste disorder and the most frequent combination was dysgeusia + hypogeusia (n=6, 12%). 4. Based on data from the medical and dental histories and examinations, the patients were assigned to 12 probable causal categories. Taste disorders due to oral mucosal diseases and idiopathic taste disorder were the most frequent (n=9; 18%, each), followed by psychogenic taste disorder (n=8; 16%), drug-induced taste disorder (n=7; 14%), and taste disorder due to dry mouth (n=6; 12%). These 5 categories of taste disorder accounted for 78% of all cases in this study.

Behcet's disease(BD) is a multisystem vasculitis that almost any organ in the body may be involved. Its diagnosis bases on clinical criteria in the absence of any specific laboratory test to confirm it. The clinical criteria proposed for the diagnosis for BD include recurrent oral and genital ulceration, skin lesion, ocular changes, and positive response to pathergy test. Besides these essential features, BD may manifest itself on the gastrointestinal tract, central nervous system, and other systemic involvements. Among these clinical features, recurrent oral ulcers are present in most BD patients, often as the initial symptom, preceding other manifestations by many years. Therefore, dentists are in the important position for the early detection and diagnosis of BD. In this case report, we are presenting a case of 6 year-old girl, who came to the pediatric dentistry department for evaluation and treatment of pain and dysphagia caused by severe recurrent oral ulcers. Through taking detailed dental and medical history and clinical examination, we reported the possibility of BD to the medical team and prescribed topical lidocaine to relief pain during swallowing. The medical team, which involved pediatrics, ophthalmology, dermatology, and gastroenterology, finally confirmed BD through various examinations. Detection of the possibility of BD in the dental field helped early diagnosis and proper management by the medical team.

It is difficult to detect and diagnose a mass at the tongue base, particularly if the mass is located under normal appearing mucosa. Computed tomography (CT), particularly post-contrast images, is useful to evaluate a tongue mass and adjacent structures including cervical lymph nodes. Nevertheless, a definitive diagnosis of a mass is obtained by histopathological examination. In this case, we describe a mass arising from the tongue body to the root in a dog. The patient was referred with ptyalism and an eating disorder. An oral examination was performed, and decreased tongue motility was observed. CT scanning was performed, and a lingual mass was detected. A lingual mass sample was collected by biopsy at the postmortem 2 months later. A histopathological examination was performed, and the lingual mass was diagnosed as squamous cell carcinoma.

Cancer cachexia-anorexia is a multi-organ metabolic syndrome characterized by anorexia and weight loss. Generally, such symptoms are a serious problem in cancer patients, adversely affecting chemotherapy success and survival rate. Cachexia has been reported to accompany up to 80% of gastrointestinal cancers, such as pancreatic, lung, and colon cancer, though it is relatively rare in lymphoma or breast cancer patients. It is also known that cancer-induced anorexia occurs independently of chemotherapy, although decreased appetite due to chemotherapy is well reported. In terms of pathoflammatory cytokines that are excessively increased by tumor tissues. Since the mechanism of cancer cachexia is not yet fully understood, there are currently no therapeutic agents or diagnostic markers to treat it. A recently published study identified a substance secreted from cancer cells that induces cancer anorexia, and the molecular mechanism causing the eating disorder was discovered. An increase in the expression of this substance has been shown to be statistically correlated with the symptoms of cachexia in cancer patients, and it is therefore expected to be applicable in the diagnosis and development of therapeutic agents for cancer cachexia. This review article aims to provide an overview of the key molecular mechanisms of the anorexia and tissue wasting caused by cancer cachexia.
