Toothache is one of the most common discomforts experienced by patients in dental clinic. If clinical and radiographic examinations do not reveal any pathologic findings, we can suspect nonodontogenic toothache. Nonodontogenic toothache can be caused by a variety of causes such as muscle disorders, sinus and nasal mucosal problems, neuropathic pain, neurovascular pain, psychogenic problems, and cardiogenic disease. A thorough history and clinical examination should be performed to confirm the cause of the pain, and more accurate diagnosis can be established through local anesthetic injection. If the nonodontogenic toothache is misdiagnosed, unnecessary dental treatment such as root canal treatment, periodontal treatment, and extraction can be performed, and the patient's pain is not alleviated through such treatment. Therefore, the cause of toothache must be diagnosed correctly before dental treatment is performed, and clinicians should be fully aware of the diseases that may cause these symptoms.

Behçet's disease (BD) is a systemic immunological disorder characterized by recurrent mucosal ulcerative lesions including oral and genital ulcerations in association with skin and ocular involvements. BD also can involve the gastrointestinal tract. Gastrointestinal involvement of BD is one of the major causes of morbidity and mortality for this disease. However, clinical data are quite limited because of the rarity of intestinal BD. Therefore, the management of intestinal BD is heavily dependent on expert opinions and standardized medical treatments of intestinal BD are yet to be established. In this brief review, the authors summarized the currently available medical treatments such as 5-aminosalicylic acids, corticosteroids, immuno-modulators, and anti-TNF agents. Moreover, we sought to suggest a treatment algorithm for intestinal BD based on the recently published and updated data.

Xerostomia is defined as the subjective complaint of dry mouth with or without hyposalivation, which is insufficient salivary secretion from salivary gland. Xerostomia can lead to multiple oral symptoms such as dental caries, halitosis, burning mouth syndrome, and oral candidiasis, which can significantly impact the well-being of patients, especially in geriatric patients who may already have compromised health. Clinical findings of xerostomia include decreased salivary flow and alterations in salivary composition. These changes can lead to various oral health problems such as dental caries, periodontitis, swallowing and speaking difficulties, taste disturbances, halitosis, mucosal diseases, and burning mouth syndrome. Recognizing these clinical manifestations is essential for early diagnosis and appropriate management. Although several reasons and risk factors have been suggested for xerostomia such as aging, chemo-radiation therapy, systemic disease, and Sjögren's syndrome, the polypharmacy is recently highlighted especially in elderly patients. Understanding the etiology and risk factors associated with xerostomia is crucial for effective management. To manage xerostomia patients, a multidisciplinary guideline should be established beyond dental care. Through this literature review, we summarized consideration for diagnostic, therapeutic, nursing essentials for the clinical guideline. By addressing the underlying causes and implementing appropriate treatment strategies, healthcare professionals can improve the quality of life for individuals suffering from xerostomia.

Objectives : The purpose of this study is to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). Materials and Methods : The author examined the extent and recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. Results : The most frequently affected sinus was maxillary sinus (82.9％), followed by anterior ethmoid sinus(67.9％), posterior ethmoid sinus(48.9％), frontal sinus(42.0％) and sphenoid sinus(41.4％). The characteristic features of CT images of the sinusitis were sinus opacification(22.4％), mucoperiosteal thickening(34.3％), and polyposis(2.0％). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babber s classification. They were 1) infundibular(13.0％), 2) ostiomeatal unit(67.4％), 3) sphenoethmoidal recess (13.0％), 4) sinonasal polyposis (9.6％) and 5) unclassifiable patterns(18.0％). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus. both posterior sinuses were 11.4％. 66.8％, 6.3％. respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5％. 79.2％. 45.1％. respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows ; normal 70.6％ and overriding type 29.4％. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9％ , rudimentary 12.5％, pterygoid recess 22.7％, anterior clinoid recess 2.7％, and both pterygoid and anterior clinoid recess type 5.2％. Conclusions : The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns, and the proximity of the important structures to the posterior paranasal sinuses. This result will aid in the interpretation of CT of PNS functionally and systemically.

A 55-year old Korean man, living in Mokpo-city, Jeollanam-do, Republic of Korea, visited a local clinic complaining of right upper quadrant pain and indigestion. At colonoscopy, he was diagnosed as having a carcinoma of the ascending colon, and thus, a palliative right hemicolectomy was performed. Subsequently, an adult fluke of Gymnophalloides seoi was incidentally found in a surgical pathology specimen of the lymph node around the colon. The worm was found to have invaded gut lymphoid tissue, with characteristic morphologies of a large oral sucker, a small ventral sucker, and a ventral pit surrounded by strong muscle fibers. This is the first reported case of mucosal tissue invasion by G. seoi in the human intestinal tract.

The effects of anti-allergic drugs on intestinal mastocytosis and the expulsion of Neodiplostomum seoulense were observed in Sprague-Dawley rats, after oral infection with 500 metacercariae. The drugs used were hydroxyzine (a histamine receptor H$_1$ blocker), cimetidine (a H$_2$ blocker), cyclosporin-A (a helper T-cell suppressant), and prednisolone (a T- and B-cell suppressant). Infected, but untreated controls, and uninfected controls, were prepared. Worm recovery rate and intestinal mastocytosis were measured on weeks 1, 2, 3, 5, and 7 post-infection. Compared with the infected controls, worm expulsion was significantly (P < 0.05) delayed in hydroxyzine- and cimetidine-treated rats, despite mastocytosis being equally marked in the duodenum of all three groups. In the cyclosporin-A- and prednisolone-treated groups, mastocytosis was suppressed, but worm expulsion was only slightly delayed, without statistical significance. Our results suggest that binding of histamine to its receptors on intestinal smooth muscles is more important in terms of the expulsion of N. seoulense from rats than the levels of histamine alone, or mastocytosis.

The intestinal histopathology and in situ postures of Gymnophalloides seoi (Digenea: Gymnophallidae) were studied using C3H/HeN and C57BL/6 mice as experimental hosts; the effects of immunosuppression were also observed. The metacercariae isolated from naturally infected oysters, 300 or 1,000 in number, were infected orally to each mouse, and the mice were killed at days 3-21 post-infection (PI). In immunocompetent (IC) mice, only a small number of flukes were found in the mucosa of the duodenum and jejunum during days 3-7 PI, with their large oral suckers pinching and sucking the root of villi. The intestinal mucosa showed mild villous atrophy crypt hyperplasia, and inflammations in the villous stroma and crypt, with remarkable goblet cell hyperplasia. These mucosal changes were almost restored after days 14-21 PI. In immunosuppressed (IS) mice. displacement as well as complete loss of villi adjacent to the flukes was frequently encountered, otherwise the histopathology was generally mild, with minimal goblet cell hyperplasia. In these mice, numerous flukes were found, and it seemed that they were actively moving and rotating in situ. Several flukes were found to have invaded into the submucosa, almost facing the serosa. These results indicate that in IC mice the intestinal histopathology caused by G. seoi is generally mild, and the flukes do not penetrate beyond the mucosa, however, in IS mice. the flukes can cause severe destruction of neighboring villi. and some of them invade into the submucosa.
