Objectives: The purpose is to establish positive relationships between pediatric patients, their guardians, and dental workers by investigating behavioral induction methods used in pediatric treatment and to encourage active cooperation during dental treatment of pediatric patients, leading to successful treatment. Methods: From March 2023 to September 2023, general hospitals, dental hospitals, and dental clinics were randomly selected and a survey was conducted on guardians of pediatric patients and dental workers, and a total of 154 copies were used in the final analysis. Results: The difference in perception of physical restraint as a behavioral induction method was that 49 people (65.3%) perceived that guardians could only allow physical methods that would not put them in dangerous situations, while dental workers could only accept physical methods that would not put them in dangerous situations. Only 41 people (51.9%) could allow it. Conclusions In the clinic, a positive relationship must be maintained between dentists, patients, and guardians, and effective behavioral induction methods must be applied to maximize the efficiency of pediatric dental care.

PURPOSE: Population-based studies have shown positive associations between migraine and irritable bowel syndrome, colitis and peptic ulcer and migraine prevalence was higher among patients with dysmotility-like dyspepsia or nausea/vomiting. The aim of this study was to investigate clinical manifestation between primary headache with epigastric pain or tenderness(EPT) and primary headache without EPT. METHODS: We retrospectively reviewed the medical records of 58 patients who were diagnosed primary headache[by ICHD-II(2004)] at Incheon St. Mary Hospital from January, 2006 to December, 2007. Their clinical characteristics such as age, sex, frequency & severity of headache and associated symptoms & signs were analysed. RESULTS: The rate of headache associated with EPT were 36% of migraine cases, 50% of tension-type headache cases, and 100% of unclassified headache cases. Headache with EPT were at a high rate in female. Headache with EPT were more severe than one without EPT. Regulation of behavior, diet and sleep pattern had improved severity of headache in 71% of migraine without EPT and 94% of tension-type headache without EPT, but in 12% of migraine with EPT and 18% of tension-type headache with EPT. Headache disappeared in 64% of migraine with EPT and 53% of tension-type headache by additional regular antiacid medication. CONCLUSION: Our study supports any specific correlation between headache and EPT, but further studies are needed.

This study was performed to find out the influences of ethanol on the metabolism of trichloroethylene(TRI) in rats. TRI in corn oil at the dosage of 150, 300, 600 mg/kg was injected peritoneally once a day for two days to two groups. In one group ethanol(4 g/kg) was taken orally 30 minutes before TRI injection, and the other group ethanol was not. The results of experiments are as follows: 1. The contents of cytochrome P-450 and b5 had inverse relationship with in-jected TRI amounts in both groups. 2. The activity of NADPH P-450 reductase was decreased slowly in TRI injected group related with TRI amount, but decreased drastically in the group pretreated with ethanol. 3. The activity of NADH b5 reductase had relationship with injected TRI amount, but the statistical significance was found only in the groups of 300 and 600 mg/kg of TRI injected without relevance to ethanol when compared with the group that was not injected. 4. The activity of ADH was more decreased and ALDH activity was more increased in groups that TRI injected and ethanol was pretreated with ethanol groups than in group without any treatment. These results suggest that ethanol may inhibit epoxide formulation, the first step or TRI metabolism, and change from TCE-OH to TCA also.

BACKGROUND: Increasing evidence supports an association between age-related loss of muscle mass and insulin resistance. However, the association has not been fully investigated in the general population. Thus, we investigated the association between appendicular skeletal muscle mass (ASM) and insulin resistance in an elderly Korean population. METHODS: This cross-sectional study included 158 men (mean age, 71.8) and 241 women (mean age, 70.6) from the Korean Social Life, Health and Aging Project, which started in 2011. In this study, ASM was measured by bioelectrical impedance analysis and was analyzed in three forms: ASM (kg), ASM/height2 (kg/m2), and ASM/weight (%). The homeostasis model assessment of insulin resistance (HOMA-IR) was used as a measure of insulin resistance. The relationships between the ASM values and the HOMA-IR were investigated by multiple linear regression models. RESULTS: The HOMA-IR was positively associated with ASM (beta=0.43, P<0.0001) and ASM/height2 (beta=0.36, P<0.0001) when adjusted for sex and age. However, after additional adjustment for body weight, HOMA-IR was inversely associated with ASM (beta=-0.43, P<0.001) and ASM/height2 (beta=-0.30, P=0.001). Adjustment for other potential confounders did not change these associations. Conversely, HOMA-IR was consistently and inversely associated with ASM/weight before and after adjustment for other potential confounders. CONCLUSION: Our results support the idea that lower skeletal muscle mass is independently associated with insulin resistance in older adults. When evaluating sarcopenia or muscle-related conditions in older adults, their whole body sizes also need to be considered.

Transvenous embolization has become the treatment of choice for cavernous sinus dural arteriovenous fistula(cDAVF). However, there are potential complications associated with this procedure such as cranial nerve palsies and venous perforations. A 66-year-old woman presented with a 2-week left periorbital swelling and conjunctival injection. Brain MRI showed engorgement of the left superior ophthalmic vein. Cerebral angiography revealed a dural arteriovenous shunt of the cavernous sinus with retrograde venous drainage into the superior ophthalmic vein. Her proptosis and conjunctival injection resolved completely after transvenous embolization of cDAVF. However, an abducens nerve palsy developed the day after the procedure, which, fortunately, resolved spontaneously. She was symptom-free at the follow- up evaluation 2 months later. The abducens nerve palsy related to the transvenous embolization of cDAVF was presu- med due to either dense packing of the sinus, venous thrombosis, or direct nerve injury. We report a case of transient abducens nerve palsy associated with transvenous embolization of cDAVF, suggesting the benign course of this com- plication.

Objectives: This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health. Methods: A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared. Results: Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P<0.05). Measurements of the PHP and Turesky plaque indices showed a significant difference in the experimental and control groups after 4 weeks (P<0.05). Compared to the PHP index before the experiment, that of the experimental group showed a significant index decrease after 2 weeks (P<0.05). Results of measuring bad breath through a BB checker showed a statistically significant difference between the experimental and control groups after 4 weeks (P<0.05). Conclusions Oral mouthwash products containing cetylpyridinium chloride and zinc acetate relieves gingivitis, removes bacterial plaque, and reduces bad breath.

PURPOSE: This study was designed to assess the clinical manifestations and the effect on prognosis of seizures in children with acute lymphoblastic leukemia(ALL). METHODS: The study group consisted of 20 patients(10 males and 10 females) who experienced seizures out of the 198 pediatric ALL patients(117 males and 81 females) who were diagnosed and treated at the Department of Pediatrics, St. Mary's Hospital, the Catholic University of Korea. RESULTS: The overall incidence of seizure developing after the diagnosis of ALL was 10.1% and in 11 patients(5.6%), seizure recurred one or more times. An average of 6.5+/-3.6 months(range 0-42 months) elapsed between the beginning of treatment and the new onset of seizures. In 13 patients(65%), the first seizure occurred during the induction or re-induction chemotherapy phase. Seizure type was partial seizure in 11 patients(55%), and generalized seizure in 9 patients(45%). In 15 patients(88.2%), brain imaging study showed abnormal findings and in 18 patients(90%), EEG revealed abnormal findings. 11 patients were diagnosed with epilepsy and were treated with long-term anticonvulsants. In these patients, 4 patients(36.4%) had no seizure recurrence, but 2 patients(18.2%) showed no response to anticonvulsants. The 5-year survival rate of the patients experiencing seizures was 47%, while the rate was 78% for those did not experience seizures (P<0.001). CONCLUSION: Seizures in pediatric patients with ALL was closely related to the 5-year survival rate. Therefore, these patients require early careful observation, evaluation and intensive care. Also, further studies such as ways to diminish the side effects of antileukemic agents are necessary to reduce the risk of seizure.

BACKGROUND AND OBJECTIVES: Chlamydia pneumoniae (CP) has been linked with atherosclerosis. While several studies have shown that CP contributes to the acceleration of atherosclerotic lesions, any studies on the initiation of atherosclerosis are sparse. The present study investigated whether CP infection could initiate atherosclerotic lesions in rats that are known to be resistant to atherosclerosis; further, we investigated if these lesions do form, then how does the CP participate in this and develop of atherosclerosis in these rats. MATERIALS AND METHODS: Thirty 11-week-old Otsuka Long-Evans Tokushima Fatty (OLETF) rats, thirty type 2 diabetic rats and thirty age-matched Long-Evans Tokushima Fatty (LETO) rats that were maintained on a high-cholesterol diet were either mock-inoculated or inoculated intranasally 3 times at 11, 13 and 15 weeks of age. The serum levels of the lipid profiles, plasminogen activator inhibitor-1 (PAI-1), monocyte chemoattractant protein-1 (MCP-1) and C-reactive protein (CRP) were measured by performing ELISA at 24 weeks and 40 weeks of age. The atherosclerotic lesion areas were analyzed, and immunohistochemical staining using chlamydia genus-specific monoclonal antibody and PDGF-B was performed in the ascending aorta at 40 weeks of age. RESULTS: Immunohistochemical staining with using specific monoclonal antibody demonstrated CP infection in the vessel walls. The serum PAI-1 level of the OLETF rats was higher than that of the LETO rats (p<0.05) regardless of the state of the CP infection, but there were no differences in the serum MCP-1 and CRP levels between the OLETF rats and the LETO rats. While no atherosclerotic lesion was observed in the mock-infected LETO rats, early-to-advanced atherosclerotic lesions were found in the other rat groups. CP-infected OLETF rats showed more advanced atherosclerotic lesions and greater mean lesion areas than the other rat groups (LT-N, 0 mm2; LETO-CP, 3.29+/-1.23 mm2; OT-N, 4.91+/-2.11 mm2; OT-CP, 9.20+/-4.62 mm2)(p<0.05). The characteristics of the atherosclerotic lesions in the rats were intimal thickening that was mainly composed of smooth muscle cells. The atherosclerotic lesion area positively correlated with the presence and the extent of PDGF-B staining in the aortic wall (p<0.01). CONCLUSION: Chronic infection of CP in the vessel walls initiated the development of atherosclerosis in the LETO rats and it accelerated the atherosclerosis in the OLETF rats. CP-induced smooth muscle proliferation and the resultant intimal thickening may be mediated by PDGF-B in these atherosclerotic lesions.

PURPOSE: The aims of this study were to introduce a method of percutaneous carpal tunnel release and report the results of our experience. MATERIALS AND METHODS: A percutaneous carpal tunnel release was performed using a curved hemostat and a meniscectomy hook knife through a small transverse incision at the proximal wrist crease. Among 125 cases from 81 patients, 91 wrists from 58 patients were evaluated retrospectively in terms of the symptomatic resolution and complications. The mean follow up period was 38.9 months ranging from 12 to 118 months. RESULTS: All but one cases (99%) showed a complete symptomatic resolution or a marked improvement postoperatively, and 94.5% of cases were satisfied with the final result. Two patients had a second operation, one chronic renal failure patient showed recurrent symptoms after an initial improvement and the other showed persistent symptoms. There were two superficial palmar arch injuries and one digital nerve injury. However two of them were the earliest cases of an inexperienced surgeons. CONCLUSION: When an experienced surgeon performs a percutaneous carpal tunnel release meticulously, it is a safe and reliable method with the benefits of less postoperative pain and an early recovery.

As chorion and amnion fusion usually occurs between 14 and 16 weeks of gestation, sonographic identification of chorion and amniotic membrane separation is a normal finding before 14 weeks. However, persistent separation after 16 weeks of gestation is considered rare and abnormal findings. Complete chorioamniotic membrane separation (CMS) may occur spontaneously, but has also been described as a complication of all invasive intrauterine procedures, including amniocentesis. Complete CMS have a significant morbidity and mortality due to intrauterine fetal death, cord complications, and preterm delivery. Aggressive treatment with hospitalization is necessary. We now report 2 cases of complete CMS identified by prenatal ultrasound; 1 in spontaneous complete CMS diagnosed at 24 weeks of gestation, and health premature child was born at 29+3 weeks of gestation, who was alive and well at present; 1 in complete CMS diagnosed at 21 weeks of gestation after amniocentesis, and fetal demise at 24 weeks of gestation due to cord strangulation by an amniotic band. We experienced two cases of complete CMS and report with a brief review of literatures.
