Background/Aims: It remains unclear which maintenance treatment modality is most appropriate for mild gastroesophageal reflux disease (GERD).We aimed to compare on-demand treatment with continuous treatment using a proton pump inhibitor (PPI) in the maintenance treatment for patients with non-erosive GERD or mild erosive esophagitis. Methods: Patients whose GERD symptoms improved after 4 weeks of standard dose PPI treatment were prospectively enrolled at 25 hospitals.Subsequently, the enrolled patients were randomly assigned to either an on-demand or a continuous maintenance treatment group, and followed in an 8-week interval for up to 24 weeks. Results: A total of 304 patients were randomized to maintenance treatment (continuous, n = 151 vs on-demand, n = 153). The primary outcome, the overall proportion of unwillingness to continue the assigned maintenance treatment modality, failed to confirm the noninferiority of on-demand treatment (45.9%) compared to continuous treatment (36.1%). Compared with the on-demand group, the GERD symptom and health-related quality of life scores significantly more improved and the overall satisfaction score was significantly higher in the continuous treatment group, particularly at week 8 and week 16 of maintenance treatment. Work impairment scores were not different in the 2 groups, but the prescription cost was less in the on-demand group. Serum gastrin levels significantly elevated in the continuous treatment group, but not in the on-demand group. Conclusions Continuous treatment seems to be more appropriate for the initial maintenance treatment of non-erosive GERD or mild erosive esophagitis than on-demand treatment. Stepping down to on-demand treatment needs to be considered after a sufficient period of continuous treatment.

Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the “2019 Seoul Consensus on Esophageal Achalasia Guidelines”) were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.

Tinea incognito (TI) is a dermatophytic infection which has lost its typical clinical appearance because of improper use of steroids or calcineurin inhibitors. The incidence of TI is increasing nowadays. We conducted retrospective review on 283 patients with TI from 25 dermatology training hospitals in Korea from 2002-2010 to investigate the demographical, clinical, and mycological characteristics of TI, and to determine the associated risk factors. More than half (59.3%) patients were previously treated by non-dermatologists or self-treated. The mean duration of TI was 15.0 +/- 25.3 months. The most common clinical manifestations were eczema-like lesion, psoriasis-like, and lupus erythematosus-like lesion. The trunk and face were frequently involved, and 91 patients (32.2%) also had coexisting fungal infections. Among 67 isolated strains, Trichophyton rubrum was the most frequently detected (73.1%). This is the largest study of TI reported to date and the first investigational report concerning TI in Korea. We suggest that doctors should consider TI when a patient has intractable eczema-like lesions accompanied by tinea pedis/unguium. Furthermore, there should be a policy change, which would make over-the-counter high-potency topical steroids less accessible in some countries, including Korea.

BACKGROUND AND PURPOSE: The National Institutes of Health Stroke Scale (NIHSS) is a clinical assessment tool that is widely used in clinical trials and practice to evaluate stroke-related neurological deficits. The aim of this study was to determine the validity and reliability of the Korean version of the NIHSS (K-NIHSS) for evaluating Korean stroke patients. METHODS: The K-NIHSS was translated and adapted with regard to cultural and linguistic peculiarities. To examine its content validity, we quantified the Content Validity Index (CVI), which was rated by 11 stroke experts. The validity of the K-NIHSS was assessed by comparison with the Glasgow Coma Scale (GCS), the modified Rankin Scale (mRS), and the Barthel Index. The reliability of the K-NIHSS was evaluated using the unweighted kappa statistics for multiple raters and an intraclass correlation coefficient (ICC). RESULTS: The CVI of the K-NIHSS reached 0.91-1.00. The median K-NIHSS score at baseline was 3 (interquartile range, 2-7), and the mean+/-SD score was 6.0+/-6.6. The baseline K-NIHSS had a significantly negative correlation with the GCS at baseline and the Barthel Index after 90 days. The K-NIHSS also had a significantly positive correlation with the mRS after 90 days. Facial paresis and dysarthria had moderate interrater reliability (unweighted kappa, 0.41-0.60); kappa values were substantial to excellent (unweighted kappa, >0.60) for all the other items. The ICC for the overall K-NIHSS score was 0.998. The intrarater reliability was acceptable, with a median kappa range of 0.524-1.000. CONCLUSIONS: The K-NIHSS is a valid and reliable tool for assessing neurological deficits in Korean acute stroke patients.

Mal de Meleda (MDM), also known as keratoderma palmoplantaris transgrediens, is a rare inherited form of palmoplantar keratoderma. It is characterized by erythema and hyperkeratosis of the palms and soles, extending to the dorsal aspects of the hands and feet. A 15-year-old Korean female presented with sharply demarcated hyperkeratotic plaques on the palms and soles, which extended to the dorsal surfaces of the hands and feet, in a "glove-and-socks" distribution. The histopathologic study showed marked hyperkeratosis, acanthosis, and normogranulosis, without epidermolysis. Her genetic study detected compound heterozygous mutation in exon 3 of the ARS gene encoding SLURP-1. Family history did not reveal any other affected members and no consanguineous relationship was found. In view of these findings, we diagnosed this case as the first reported sporadic case of MDM in Korea, the farthest location from the endemic island of Meleda.

BACKGROUND: Dermatological diseases can occur with atopic dermatitis. OBJECTIVE: The purpose of this study was to analyze diseases associated with atopic dermatitis in Koreans. METHODS: From November, 2007, to May, 2008, 948 patients with atopic dermatitis who visited the department of dermatology at 19 hospitals were evaluated for associated diseases. RESULTS: Of 948 patients, 53.8% (510) had symptoms associated with other dermatological diseases. In order of frequency, diseases associated with atopic dermatitis included acne, hand/foot eczema, seborrheic dermatitis, urticaria, warts, and recurrent herpes simplex. The number of associated diseases did not change significantly with the severity of atopic dermatitis. However, the incidence of hand/foot eczema and eczema herpeticum correlated significantly with the severity of atopic dermatitis. CONCLUSION: There is a distinct pattern of diseases associated with atopic dermatitis in Koreans.

BACKGROUND: From November 2006, The national health insurance system in the Republic of Korea began to cover prescribed long-term oxygen therapy (LTOT) in patients with chronic respiratory insufficiency. This study examined the current status of LTOT after national health insurance coverage. METHODS: Between November 1, 2006 and June 30, 2008, the medical records of patients who were prescribed LTOT by chest physicians were reviewed. The data was collected from 13 university hospitals. RESULTS: 197 patients (131 male and 66 female) were prescribed LTOT. The mean age was 64.3+/-13.0 years. The most common underlying disease was chronic obstructive pulmonary disease (n=103, 52.3%). Chest physicians prescribed LTOT using arterial blood gas analysis or a pulse oxymeter (74.6%), symptoms (14%), or a pulmonary function test (11.2%). The mean oxygen flow rate was 1.56+/-0.68 L/min at rest, 2.08+/-0.91 L/min during exercise or 1.51+/-0.75 L/min during sleep. Most patients (98.3%) used oxygen concentrators. Only 19% of patients used ambulatory oxygen supplies. The oxygen saturation before and after LTOT was 83.18+/-10.48% and 91.64+/-7.1%, respectively. After LTOT, dyspnea improved in 81.2% of patients. The mean duration of LTOT was 16.85+/-6.71 hours/day. The rental cost for the oxygen concentrator and related electricity charges were 48,414+/-15,618 won/month and 40,352+/-36,815 won/month, respectively. Approximately 75% of patients had a regular visit by the company. 5.8% of patients had personal pulse oxymetry. 54.9% of patients had their oxygen saturation checked on each visit hospital. 8% of patients were current smokers. The most common complaint with LTOT was the limitation of daily activity (53%). The most common complaint with oxygen concentrators was noise (41%). CONCLUSION: The patients showed good compliance with LTOT. However, only a few patients used an ambulatory oxygen device or had their oxygen saturation measured.

BACKGROUND: The incidence of chronic obstructive pulmonary disease (COPD) is increasing and the disease is becoming an important cause of morbidity and mortality worldwide. It is important to implement evidence-based guidelines by primary care physicians (PCPs) to establish qualified management of COPD patients. The aim of this survey is to investigate the pattern of COPD management among PCPs and to apply it to the development of Korean COPD guidelines. METHODS: A web-based questionnaire was prepared that consisted of 25 questions on the pattern of COPD management. A total of 217 PCPs participated in the survey from June 2006 to May 2007. RESULTS: Many PCPs (61.8%) possessed a spirometer, but the application rate was relatively low (35.8%) and more than half of the COPD patients (57%) did not receive a diagnosis based on spirometry. Administration of oral medication was preferred than the administration of inhaled medication for both stable COPD and acutely exacerbated COPD. More than 90% of the PCPs endorsed educational measures to quit smoking and vaccinate against influenza. It was noted that 56.7% of the PCPs were aware of the GOLD guidelines, but only 7.3% tended to fully implement the recommendations of the guidelines in daily practice. CONCLUSION: The results of the survey indicate that despite the high awareness rate of the current COPD guidelines, deficits exist among the PCPs with respect to the diagnosis and treatment of COPD. The results of this survey should be applied for the development of new COPD guidelines in order to decrease the discrepancy between the guidelines and the daily practice of the PCPs.

PURPOSE: The purposes of this study were to measure the degree of uncertainty in illness, hope, and spiritual well-being and to examine the relationship among uncertainty in illness, hope, and spiritual well-being of cancer patients. METHOD: The data were derived from answers to questionnaires obtained from 93 cancer patients at one general hospital in J area from April 6, 2004 to May 8, 2004. The collected data were analyzed by SSPS 10.0. RESULTS: The mean score of uncertainty in illness of cancer patients was 55.96. The mean score of hope of cancer patients was 79.77, and spiritual well-being was 55.20. Uncertainty in illness of cancer patients was related negatively to hope(r=-.57, p=.000). Also uncertainty in illness of cancer patients was related negatively to spiritual well-being(r=-.57, p=.000). However, hope of cancer patients was related positively to spiritual well-being(r=.67, p=.000). CONCLUSION: Higher uncertainty in illness was related to lower hope and spiritual well-being of cancer patients. Based upon these results, nurses should help patients to improve their hope and spiritual well-being through mediation of uncertainty in illness.

BACKGROUND/AIMS: It is unknown whether the prokinetics improve the quality of life in patients with functional dyspepsia. Thus, we evaluate the effect of the mosapride, selective 5-HT4 agonist, on the symptom and life quality of patients with functional dyspepsia using the Nepean dyspepsia index-Korean version (NDI-K), a reliable and validated disease-specific quality of life questionnaire. METHODS: A single, open trial was performed in 129 patients with functional dyspepsia. Patients were received mosapride 5 mg t.i.d before each meal for 4 weeks. The symptoms and quality of life were measured with the NDI-K at baseline and 4 weeks. The responsiveness of the NDI-K was evaluated by correlation with symptom scores. RESULTS: All the 15 symptom scores and the dyspepsia score decreased after treatment (p<0.05). The total symptom score decreased from 60.9 +/- 25.8 to 24.7 +/- 20.4 (p=0.001). Correlations were observed between the total symptom score and the NDI-K score (r=0.47, p=0.001), and between the total symptom score and each score in 5 subscales (r=0.25-0.44, p=0.001). The NDI-K score was significantly increased in the effective group whose dyspepsia score decreased more than 50% of the score at baseline, compared with that of ineffective group. Any significant adverse effect and prolongation of QT interval were not occurred in all patients. CONCLUSIONS: A prokinetic drug, mosapride improves the symptoms and the quality of life in patients with functional dyspepsia.
