The purpose of this study was to evaluate treatment outcome and prognosis of the patients with orofacial pain disorders who visited for treatment in the Department of Oral Medicine, Dankook University Dental Hospital from January 2002 to December 2004. Orofacial pain disorders were categorized into TMD(myogenous, arthrogenous and muscle-joint combined TMDs), neuropathic pain disorder, oral soft tissue disease and complex condition simultaneously having more and two aforementioned categories and treatment period, method and treatment outcome were evaluated. The results of this study were as follows; 1. Average longevity of treatment period was the longest in the neuropathic pain, followed by soft tissue disease, complex conditions, arthrogenous TMD, muscle-joint combined TMD and myogenous TMD in order. 2. When treatment methods were largely categorized into pharmacologic, physical and oral appliance therapy, pharmacologic therapy was used the most frequently for the patients with neuropathic pain or oral soft tissue diseases, oral appliance therapy for those with arthrogenous TMD and physical therapy for those with myogenous TMD. 3. Of physical therapeutic methods used in our clinic, EAST and microwave was employed the most frequently in the patients with myogenous TMD, ultrasound for those with arthogenous TMD and LLLT for those with neuropathic pain or oral soft tissue disease. 4. In comparison with change of pain after treatment, there existed a tendency that pain from neuropathic pain disorders persisted while pain from TMD was getting better or totally disappeared. 5. Concerning the change of mouth opening range in the TMD subgroups, there was no significant difference among the subgroups but significant difference existed among opening ranges, indicating comfortable maximum mouth opening increased the most following treatment. Improvement of active range of mouth opening was the most considerable in those with disc displacement without reduction. It can be said on the basis of the findings from this study that various treatments currently used for the orofacial pain showed good results with TMD in regards with pain control and improvement of function, suggestive of favorable prognosis, while neuropathic pain or soft tissue disease was the clinical conditions difficult to resolve, requiring a long and persistent treatment.

Purpose : In adults, valproate (VPA) has been reported to be associated with thrombocytopenia. However, few studies have investigated this association in children, and the factors affecting platelet counts remain controversial. This study was undertaken to investigate changes in platelet counts following VPA therapy and related factors in children with epilepsy. Methods : Our subjects comprised 75 epileptic children who had received VPA monotherapy for at least 1 year between January 2000 and December 2005. We regularly examined platelet counts at intervals of 6 to 12 months after baseline platelet counts before VPA treatment. We analyzed changes in platelet counts according to several factors such as sex, seizure type, underlying causes of epilepsy, age at the start of medication as well as at the last follow up, duration of VPA administration, VPA dose, serum VPA level, and body weight at the last follow up. Results : Overall, the platelet counts decreased significantly after VPA therapy. The average baseline platelet count was $312.5{\pm}109.1{\times}10^6/mL$. At the last follow up, the average platelet count was $261.7{\pm}72.2{\times}10^6/mL$. We observed the relationship between platelet counts and serum levels of VPA; while children with serum VPA <$75{\mu}g/mL$ showed no change in platelet counts (P=0.102), children with serum VPA >$75{\mu}g/mL$ showed a significant decrease in platelet counts. Conclusion : VPA may cause a significantly decreased platelet count in children with epilepsy. High serum VPA levels were associated with development of thrombocytopenia.

To identify the trend of pediatric dentistry in USA and Japan, closely related to Korean pediatric dentistry. The Japanese Journal of Pediatric Dentistry(JJPD) and The Journal of the American Academy of Pediatric Dentistry(PD) were reviewed. We collected the bibliographical data of the articles published in the two journals from 1991 to 2000. We analyzed thematic distributions and chronological changes, and then compare those of two groups. The following results were obtained: 1. The 869 articles were published in JJPD and 672 in PD. This was about 30% more in JJPD. 2. In both JJPD and PD, the case reports were a quarter of scientific articles in quantity. 3. The studies on the systemic diseases had the highest proportion in both JJPD and PD. The studies on the dental caries and restorative materials also had high proportion in both journals. 4. The studies on the sedation and biochemical survey had high proportion in PD when had low proportion in JJPD. To the contrary, The studies on the behavior science in JJPD were about double of those in PD. 5. There was no statistically significant difference in quantity between JJPD and PD in the studies on the dental caries, prevention of dental caries, community dental survey, conservative treatment, restorative materials, pulp treatment, diagnosis and treatment of malocclusion, oral pathology and minor surgery, local anesthesia and nerve tissue, traumatic injuries. 6. There was statistically significant increase in the studies on the dental equipment in JJPD and in those on restorative materials in PD. 7. There was statistically significant decrease in the studies on the prevention of dental caries and local anesthesia and nerve tissue in JJPD, and those on conservative treatment in PD.

Purpose : To report the clinical experience with amitriptyline for managing children with cyclic vomiting syndrome (CVS). Methods : Totally, eleven children (eight males) were diagnosed with CVS. Of these, medical records were reviewed for eight children treated with amitriptyline; three children were not treated because one was not followed up and two were kept under observation to study the natural course without medication, because the frequency of vomiting had recently decreased to less than one episode per year. The eight amitriptyline-treated children were divided into three groups by the therapeutic response: (1) complete remission (CR), with no recurrence of symptoms after treatment; 2) partial remission (PR), in which the frequency of symptoms decreased by almost 50% after treatment; and (3) no response. Results : For the eight amitriptyline-treated children, the mean age of symptom onset was 4.7 (0.3-7) yr and mean age at diagnosis was 8.9 (6.0-11.3) yr. The mean number of vomiting episodes was 8.8 (2-25) per year, and the duration of vomiting in each episode ranged from 3 hours to 5 days. CR was achieved in five (62.5%) of the eight amitriptyline-treated children (0.2-0.8 mg/kg/day orally, at night) and PR was achieved in three children (37.5%). Two children relapsed on discontinuation of amitriptyline by their parents decision but showed improvement on remedication. No adverse effects were noted throughout the study period. Conclusion : Amitriptyline can be used in long-term prophylaxis for the management of children with CVS aged over 6 yr. However, a large-scale study is needed to ascertain its effects.

I. Introduction : The constipation is one of the common gastrointestinal symptoms seen in the clinical practice. When people come to the clinic complaining of the constipation, it is generally one of the cases of infrequent, painful or difficult evacuation as well as the hardened feces and unsatisfactory evacuation sense. Since the constipation is heavily influenced by dietary habit as well as the social and medical environment, the diagnostic radiology is useful to establish the objective and standardized definition in consideration of those various factors before diagnosis and treatment of the constipation patient. This paper describes the study of such diagnosis. II. Main Subject : Testing of CTT (colon transit time) is key study of the colon performance. CTT is very helpful in classifying the pathologic physiological types and defining the treatment plan for the chronic constipation. The study methods include using the radipaque marker, multiple marker technique and scintigraphic measurement. The defecography is the functional radiologic examination a that provides not only the anatomical information of anorectal but also performance of the pelvic floor and rectal change during evacuation. Study of dynamic movement of the anorectal during evacuation is helpful for diagnosis and treatment planning as well as follow-up testing for the constipation patient. One of the issues essential for the case history is the thorough observation of whether the patient shows the psychic psychological symptoms such as the behavior disorder or emotional disturbance. In that case, the decision must be made whether or which type of medication is needed for such psychiatric problem. III. Conclusion : The main causes of the constipation are insufficient intake of fiber or liquid. The key objective of such tests is to check etiology of the constipation. In general, the radiological examination does not provde the colon or anorectal performance information. It is envisaged that this study will provide the information to decide the testing and treatment plans and predict the prognosis of the patient by classifying the pathologic physiological types.

While previous epidemiological studies on temporomandibular disorders (TMD) have been based on a given health center or population sample, no study has been performed on general population of Korea, especially concerning about treatment pattern such as clinician’s specialty involved in TMD treatment, types and amount of prescription medication and cost. This study aimed to investigate magnitude of health visits and treatment patterns for Korean patients with TMD through the computerized database of Health Insurance Review and Assessment Service (HIRAS). Inclusion criteria were all patients registered on the HIRAS database over 3 years' period from 2003 to 2005 and the medical records of patients with TMD as a main diagnosis were extracted. Information collected was as follows; distribution related to gender, age and region and type of hospital the patients visited, treatment duration, clinicians' specialty involved in treatment, cost, types of prescription medication and surgical treatment. The results of this study indicated that 0.15% of the population yearly sought TMD treatment, presenting with increase of incidence over the three years. Most of TMD patients were women (99.8%) and the biggest age group was second and third decades and decreased with age. Seoul and Kyeonggi province presented with higher incidence of TMD compared to the other regions of Korea, which seems to be related with magnitude of population. 56% of TMD patients visited primary care sector and the numbers of treatment visits was the highest in dental clinic (38.4%), followed by orthopedics (28%) and ENT (13.6%) clinics in order. Duration of prescription medication was the longest for anti-inflammatory analgesics, followed by antipsychotic drugs and muscle relaxants. Inpatient care related to TMD was primarily performed in dental hospital compared to medical hospital. Medical database of HIRAS provided comprehensive and vast information on epidemiologic characteristics and treatment patterns for patients seeking TMD treatment, which can be more reliable data to expect medical demand for TMD in condition that accurate diagnosis and standardized treatment is delivered in clinical settings.

This study was performed to compare the effect of hyaluronic acid(HA), vitamin I and their combinations for the prevention of postoperative intraperitioneal adhesion in dogs. Twelve mongrel dogs were divided into four groups; HA- (HA Group), vitamin E 800IU- (E8 Group), HA + vitamin E 800IU- (HA+E8 Group) and HA + vitamin E 1600IU-treated group(HA+E16 Group) with three dogs in each group. After celiotomy, five abrasions of 1$\times$1 cm area were made on the antimesenteric serosal surface of the anterior ileocecum with a No. 10 scalpel blade. The five abrasions and peritoneal cavity were coated with 25 of 0.l% HA. Oral supplements of vitamin E were given from the fifth day before the operation to the fourteenth day after the operation. Hematologic values were evaluated before the operation and on the 1st, 4th, 7th and 14th day after the operation. The locations and scores of adhesion were assessed through the second operation on the 21st day after the first operation. The adhesions were located on serosa to mesentary(43.3%)), serosa to serosa(20%), serosa to omentum(5%) and serosa to parietal peritoneum(1.7%). The incidences of adhesion in HA, E8, HA+E8 and HA+E16 groups were 80%, 100%, 47% and 53%, respectively. The scores of adhesion in HA+E8 group(p < 0.05) were lower than those in other groups. This study showed that the combination of HA and vitamin E 800IU was significantly effective in reducing the intraperitoneal adhesion in dogs.

Objectives: In narcoleptic patients diagnosed with ICSD (international classification of sleep disorders, 1990) criteria, nocturnal polysomnography, and MSLT (multiple sleep latency test), we tried to find characteristic features of quantitative electroencephalography (QEEG) in a wakeful state. Methods: We compared eight drug-free narcoleptic patients with sex- and age-matched normal controls, using computerized electroencephalographic mapping technique and spectral analysis. Absolute power, relative power, interhemispheric asymmetry, interhemispheric and intrahemispheric coherence, and mean frequency in each frequency band (delta, theta, alpha and beta) were measured and analyzed. Results: Compared with normal controls, narcoleptic patients showed decrease in monopolar interhemispheric coherence of alpha frequency bands in occipital ($O_1/O_2$), parietal ($P_3/P_4$), and temporal ($T_5/T_6$) areas and beta frequency band in the occipital ($O_1/O_2$) area. Monopolar intrahemispheric coherences of alpha frequency bands in left hemispheric areas ($T_3/T_5$, $C_3/P_3$ & $F_3/O_1$) decreased. Decrease of monopolar interhemispheric asymmetry of delta frequency band in the occipital ($O_1/O_2$) area was also noted. The monopolar absolute powers of beta frequency bands decreased in occipital ($O_2,\;O_z$) areas. Conclusion: Decreases in coherences of narcoleptic patients compared with normal controls may indicate fewer posterior neocortical interhemispheric neuronal connections, and fewer left intrahemispheric neuronal connections than normal controls in a wakeful state. Therefore, we suggest that abnormal neurophysiological sites of narcolepsy may involve complex areas such as neocortex and subcortex as well as the brainstem.

Background : The prevalence of multidrug resistant tuberculosis (MDR-TB), resistant to isoniazid (INH) and rifampin (RFP), was 5.3% worldwide in 1995 and its increment has raised important public health problems. Resistance to RFP, one of the key drugs in the treatment of tuberculosis, results in grim clinical outcome. Recently rapid detection of RFP-resistant mutations in rpoB gene based on PCR method has become available. This study evaluated the prevalence of RFP resistance in first diagnosed, treatment failure, and recurred patients using INNO-LiPA test, and compared the results of INNO-LiPA with those of conventional mycobacterial drug susceptibility test. Methods : Forty-six patients, who were diagnosed of pulmonary tuberculosis and had revealed positive sputum AFB smear, were enrolled in this study from 1998 to 2002. The cases were classified as one three groups; first diagnosed, treatment failure, or recurred. RFP resistance was studied using an INNO-LiPA Rif. TB kit and compared with that obtained from drug susceptibility based on M. tuberculosis culture study. Results : Twenty-one out of 46 patients were enrolled under first diagnosis of pulmonary tuberculosis, 17 under treatment failure with first line drugs, and 8 under recurrence. The positive and negative predictive values of INNO-LiPA test in diagnosis in RFP resistant tuberculosis compared with conventional mycobacterial drug susceptibility test were 85.7% and 76.0%, respectively. INNO-LiPA result revealed rpoB gene mutation in 20 (80.0%) out of 25 patients who were diagnosed as treatment failure or recurrence, but in only 4 (19.0%) out of 21 patients who were first diagnosed as pulmonary tuberculosis. Conclusion : This study showed that RFP resistance could be diagnosed rapidly and accurately using INNO-LiPA test and that this test might be helpful for choosing second line anti-mycobacterial drugs. It might be of great help in clinical diagnosis and decision when used in complimentarily with drug susceptibility test based on M. tuberculosis culture.
