목 적 : 다른 특별한 병력이 없는 영아들에서 흡인으로 인한 만성 기침이 의심되는 경우, 상부 식도 24시간 pH 검사를 시행하여, 그 결과를 일반적으로 위식도 역류를 진단하기 위해 시행하는 하부 식도 24시간 pH 검사의 결과치와 비교하여 상부 식도 24시간 pH 검사에 대한 유용성을 평가하고자 하였다. 방 법 : 3주 이상의 만성 기침을 주소로 인하대병원 소아과에 입원한 1세 이하 영아들 중, 흉부 단순 촬영상 특이소견이 없고 그 원인이 뚜렷하지 않은 환아들을 상대로 흉부 전산화 단층 촬영을 시행한 결과, 의존성 위치에서 폐 경화를 보여 역류로 인한 흡인의 가능성이 높은 17명의 환아들을 본 연구의 대상으로 하여 상부와 하부 식도 24시간 pH 검사를 시행하였다. 결 과 : 1) 대상 환아는 17명(남아 12명, 여아 5명)으로 평균 연령은 4.3개월($4.3{\pm}1.8$개월)이었다. 2) 총 17명의 환아들 중, 상부 식도에서 병적인 위산 역류를 보인 환아는 15명(88.2%)이었고, 하부 식도에서는 4명(23.5%)으로, 상부 식도에서 이상 소견을 보인 환아들이 더 많았다(P<0.01). 하부 식도에서 정상 범위의 역류를 보이더라도 상부 식도에서 병적인 역류를 보이는 경우는 13명 중 12명(92.3%)이었다. 3) 상부 식도 24시간 pH 검사에서 역류지표와 역류빈도가 하부 식도 24시간 pH 검사에서보다 통계적으로 의미 있게 낮았다(P<0.05). 4) 하부 식도 24시간 pH 검사 결과와 상부 식도 24시간 pH 검사 결과들 사이에는 상관관계가 없었다. 5) 하부 식도 24시간 pH 검사에 있어서, 위식도 역류로 진단을 받은 군(group 1)과 정상으로 진단을 받은 군(group 2)의 상부 식도 24시간 pH 검사 결과와의 차이를 비교했을 때, group 2에서 상부 식도에서도 역류빈도가 통계적으로 의미 있게 낮았다(P<0.05). 결 론 : 만성 기침을 보이는 영아들에 있어서 뚜렷한 위식도 역류 증상은 없지만 위식도 역류에 의한 흡인이 의심되는 경우에 상부 식도 24시간 pH 검사가 필수적인 진단 방법으로 제시하는 것에 본 연구의 의의가 있다.

Background and Objectives : Gastric acid reflux has been suggested to have an association with sleep apnea(SA). This study's aim is to evaluate the relationship between reflux laryngitis and SA through the fact that the treatment of reflux laryngitis may impact the snoring and SA related symptoms in selective individuals. Methods : Population consist of 24 males and 10 female aged 34 to 66 years(mean age 50 years) confirmed by Reflux Finding Score(RFS) of PC Belafsky. Thirty four patients with reflux laryngitis and associated symptoms of SA were treated with proton pump inhibitor(Rabeprazole sodium 10mg/day) for 60 days. The degree of snoring and apnea related symptoms were evaluated using questionnaires, and palatine tonsillar hypertropy(PTH) and RFS were compared preoperatively and postoperatively. Results : After antireflux treatment for 60 days, the snoring(p=0.039), daytime sleepiness(p=0.002), and concentration(p=0.011) were significantly improved(p<0.05) and RFS was significantly decreased(p=0.000), but morning headache(p=0.057) and sleep apnea(p=0.083) were not significantly improved(p>0.05) and PTH was not significantly decreased(p=0.328). Conclusion : Treatment of reflux laryngitis significantly impacted the snoring, daytime sleepiness, and concentration in selective individuals. These results suggest some close relationship between reflux laryngitis and SA, and the treatment of reflux laryngitis may be some effective in those with both disorders.

Dysphonia is a medical terminology for voice disorders characterized by hoarseness, harshness, weakness, or even loss of voice ; any impairment in ability to produce voice sounds using the vocal organs, larynx, The causes of dysphonia can be classified into two groups, organic and functional. Functional dysphonia includes spasmodic dysphonia, muscle tension dysphonia, mutational dysphonia and conversion dysphonia, etc, The findings of laryngoscopy in these dysphonia are almost normal. Therefore, physicians should diagnosis these diseases from careful history taking and abundant understandings about the phonation pattern, Organic dysphonia is caused by anatomical problems in the larynx, especially on the vocal fold, Some lesions, however, are not easily found because these lesions are too small, or located on the lower lip of vibrating vocal fold. Laryngopharyngeal reflux induced laryngitis, vascular lesions, sulcus vocalis, vocal atropy including presbylaryngis, and mucosal tears are common lesions easily missed in laryngoscopy, Therefore, a high index of suspicion is necessary to avoid missing vocal fold mucosal lesions, and the strobovideolaryngoscopy is indispensable in making the diagnosis,

Background and Objectives： Complications arising from endotracheal intubation are uncommon but, when they do occur, can be significant. Placement of an endotracheal tube frequently results in trauma to the underlying laryngeal and tracheal tissue, although the trauma is usually reversible. Occasionally, these changes can be of a more permanent nature and result in severe impairment of the airway and/or voice. It is proposed that a common factor-gastroesophageal reflux-might be responsible. This study was performed in order to develop the animal model of LPRD using rats and investigated that LPRD could produce significant damage to larynx especially vocal cords. Materials and Methods : The each four rats were used in the experiment and control study. Each was anesthetized and larynx was exposed and injured in the unilateral aritenoid. Injured site was contact with normal saline(control group) and synthetic gastric juice(experimental group). The larynx was examined after 7days in normal environment. Results : All was survived in the control group and two was survived in the experimental group. In the control group, some inflammation cells was found but in the experimental group, granulation was found. Conclusion : We developed animal model of LPRD using rat and thought LPRD may Play an important role in the development of permanent laryngeal injury.

부식이란 산성의 화학적 물질에 의한 치아 경조직의 손상으로 정의된다. 이에 대한 원인인 산성 음식, 약물, 작업환경 등의 외부적 원인과 위장관 장애에 의한 위산의 역류나 거식증에 의한 의도적 구토의 내부적 원인에 의해 발생된다. 이는 임상적 증상의 심각도에 따라 레진 충전, 라미네이트 수복 또는 전장관 수복으로 치료한다. 본 증례는 잦은 산성 과일의 섭취로 인한 전치부 순측 부식 및 거식증으로 인한 의도적 구토로 전치부 구개측 부식이 일어난 드문 상황에 대한 치료이다.

Laryngopharyngeal reflux(LPR) is one firm of the gastroesophageal reflux diseases(GERD). It is known to cause various kinds of otolaryngologic symptoms such as hoarseness, foreign body sensation in throat, chronic throat clearing, chronic cough, etc. Disease entities diagnosed by otolaryngologists as posterior laryngitis, globus pharyngeus should be suspected as LPR-related diseases. In this multi-center trial, we tried to evaluate the effect of cisapride(10mg tid) on LPR-related symptoms as the part I study(CIS-KOR-051) in 19 centers, and as the part II study(CIS-KOR-052) comparative evaluation of effect between cisapride(10mg tid) and ranitidine(150mg bid) on LPR-related symptoms in 4 centers. In part I study, efficacy of cisapride on LPR-related symptoms after 4 weeks was 53.5% and that of after 8weeks was 77.9% in per protocol(PPA) analysis group. In part II study, efficacy of the cisapride was much better than that of ranitidine not only from 8 weeks trial(p<0.001) but also from 4 weeks trial(p<0.021) in PPA group. In the multiple logistic regression analysis among the parameters which affect the efficacy of the treatment, cisapride prescribed group showed 10 times greater than that of ranitidine prescribed group(p<0.0001, Odds ratio : 10) in PPA group. LPR was proved by 24Hr double probe pHmetry in 13 patients out of 19 patients tested(68.4%). Thus these results indicated that inducing the improvement of motility functions could affect the amelioration of the LPR-related symptoms much better than reducing acid secretion from the stomach. And maybe it suggests that LPR-related symptoms mainly developed by the reduced motility functions of the esophagus and/or delayed gastric emptying.

Background and objective : Rabeprazole is a new generation proton pump inhibitor, which has a rapid onset after first dose, predictable efficacy in all patients regardless of CYP2C19 genotype status, and less nocturnal acid breakthrough. The aim of the study is to investigate clinical efficacy and safety of rabeprazole sodium (Pariet 10mg qd)when administered once daily to patients with laryngopharyngeal reflux(LPR) disease. Methods : Among the patients who had visited the Department of Otolaryngology, those with LPR symptoms, had undergone laryngoscopy. Symptoms and endoscopic laryngeal sings were recorded initially, at 1 month, 2 months, 3 months, and more than 3 months, All patients were evaluated for clinical efficacy on the basis of symptom scores, reflux finding score(RFS), and side effects. Results : In general, most symptom scores and RFS improved over the time. Efficacy of the Pariet on LPR-related symptoms were $63.2\%,\;77.5\%,\;78.7\%,\;and\;90.9\%$ before 4 weeks, 4 to 8 weeks, 8 to 12 weeks, and after 12 weeks respectively. Efficacy on the RFS were $61.8\%,\;78.4\%,\;82.9\%,\;and\;85.5\%$ before 4 weeks, 4 to 8 weeks, 8 to 12 weeks, and after 12 weeks respectively. Pariet was well tolerated and was associated with few drug-related side effects. Conclusion Because of its efficacy and safety, Pariet may prove to be an alternative to currently available proton pump inhibitors.
