Characteristics of symptomatic belching in patients with belching disorder and patients who exhibit gastroesophageal reflux disease with belching.

BACKGROUND/AIMS: Belching disorder (BD) is clinically distinct from gastroesophageal reflux disease (GERD) with belching. Supragastric belching (SGB) is closely associated with reflux episodes. This study investigates belch characteristics in association with reflux, compared between patients with BD and those who had GERD with belching. METHODS: Impedance pH monitoring data from 10 patients with BD and 10 patients with GERD who exhibited belching were retrospectively analyzed. Belches were considered "isolated" or "reflux-related" and acidic/non-acidic. Belch characteristics were compared between patients with BD and those with GERD. RESULTS: Symptomatic belches were more frequent in patients with BD than in patients with GERD (median, 160.5 vs 56.0, P < 0.05). SGB was the most common type in both groups; common subtypes comprised "isolated" in patients with BD and "isolated during the reflux period" in patients with GERD. Reflux-related SGB was more common in patients with GERD than in BD (78.3% vs 45.2%, P < 0.005). Both "preceding belching" including the reflux period and acidic SGB were more common in patients with GERD than in BD (31.8% vs 8.6% and 38.1% vs 8.9%, both P < 0.05). Supragastric belch number positively correlated with all reflux episodes in patients with GERD (adjusted R2 = 0.572, P = 0.007). CONCLUSIONS: BD is characterized by more belching, compared to GERD. SGB is more frequently associated with reflux in GERD than in BD; acidity may be related to GERD. In BD, SGB is typically non-acidic and unrelated to reflux. Distinct SGB characteristics may reflect different pathogenic mechanisms of reflux and associated symptoms.

Clinical outcomes of positive resection margin after endoscopic mucosal resection of early colon cancers.

BACKGROUND/AIMS: When determining the subsequent management after endoscopic resection of the early colon cancer (ECC), various factors including the margin status should be considered. This study assessed the subsequent management and outcomes of ECCs according to margin status. METHODS: We examined the data of 223 ECCs treated by endoscopic mucosal resection (EMR) from 215 patients during 2004 to 2014, and all patients were followed-up at least for 2 years. RESULTS: According to histological analyses, the margin statuses of all lesions after EMR were as follows: 138 cases (61.9%) were negative, 65 cases (29.1%) were positive for dysplastic cells on the resection margins, and 20 cases (8.9%) were uncertain. The decision regarding subsequent management was affected not only by pathologic outcomes but also by the endoscopist's opinion on whether complete resection was obtained. Surgery was preferred if the lesion extended to the submucosa (odds ratio [OR], 25.46; 95% confidence interval [CI], 7.09-91.42), the endoscopic resection was presumed incomplete (OR, 15.55; 95% CI, 4.28-56.56), or the lymph system was invaded (OR, 13.69; 95% CI, 1.76-106.57). Fourteen patients (6.2%) had residual or recurrent malignancies at the site of the previous ECC resection and were significantly associated with presumed incomplete endoscopic resection (OR, 4.59; 95% CI, 1.21-17.39) and submucosal invasion (OR, 5.14; 95% CI, 1.18-22.34). CONCLUSIONS: Subsequent surgery was associated with submucosa invasion, lymphatic invasion, and cancer-positive margins. Presumed completeness of the resection may be helpful for guiding the subsequent management of patients who undergo endoscopic resection of ECC.

Clinical outcomes of patients with a single hepatocellular carcinoma less than 5 cm treated with transarterial chemoembolization.

BACKGROUND/AIMS: Transarterial chemoembolization (TACE) is performed for single hepatocellular carcinoma (HCC) that are not eligible for surgery or ablation therapy. We investigated the clinical outcomes of patients with a single HCC ≤ 5 cm treated with TACE. METHODS: This study analyzed 175 consecutive patients who underwent TACE as an initial treatment for single HCC ≤ 5 cm. Predictive factors for complete response (CR), recurrence after CR, and overall survival (OS) were evaluated. RESULTS: Total 119 patients (68%) achieved CR after TACE. Tumor size < 3 cm and hepatitis B virus infection were significant predictors of CR (p < 0.05). Recurrent HCC was detected in 73 patients (61.3%) after CR. Age > 65 years and absence of liver cirrhosis were predictive factors for non-recurrence after CR (p < 0.05). The OS for all patients was 80.7 ± 5.6 months, and the 1-, 3-, and 5-year OS rates were 88.1%, 64.8%, and 49.9%, respectively. In multivariate analysis for OS, CR (hazard ratio [HR], 0.467; 95% confidence interval [CI], 0.292 to 0.747) and Child class A (HR, 0.390; 95% CI, 0.243 to 0.626) were significant factors. The OS for the CR and Child class A group were 92 and 93.6 months, respectively, and that of the non-CR and Child B, C group were 53.3 and 50.7 months, respectively (p < 0.001). CONCLUSION: TACE can be a valid treatment in patients with a single HCC ≤ 5 cm not suitable for curative treatment, especially in patients with Child class A and CR after TACE.

Effects of patient satisfaction and confidence on the success of treatment of combined rheumatic disease and interstitial lung disease in a multidisciplinary outpatient clinic.

OBJECTIVES: Multidisciplinary discussions (MDDs) have emphasized improve medical services and outcomes. We used a multidisciplinary approach to explore whether patient emotional satisfaction and confidence affected treatment outcomes in rheumatic disease (RD)-related interstitial lung disease (ILD). METHODS: From December 2015 to April 2017, we evaluated 23 patients with RD and ILD and 21 with idiopathic pulmonary fibrosis (IPF). Patients with RD and ILD were managed with MDDs. Patients with IPF received standardized medical care by the same pulmonologist. All patients completed brief multiple-choice questionnaires exploring their perceptions of their illnesses and their attitudes toward medical treatment, and completed the Patient Health Questionnaire-2. RESULTS: The MDD patients could more easily identify disease symptoms regardless of age stratification (under 65 age: P = 0.020, 65 years or older: P = 0.003). Among the 65 years or older group, it shows higher levels of illness perception in terms of disease timeline in the MDD group (P = 0.035). Also, the MDD group reported higher levels of satisfaction in terms of the explanations they received and their involvement in discussion, and greater satisfaction with medical staff. However, the groups did not differ significantly between treatment outcomes such as changes in forced vital capacity, the diffusion capacity of carbon monoxide, or changes in high-resolution computed tomography. CONCLUSIONS: MDDs afforded satisfactory management compared with standardized medical care. The MDD group felt better attention fromand satisfaction with medical staff, and had greater identification in their treatment. Further research engaging in MDDs with a comparable control group is required.

Predictive Factors for Complete Response and Recurrence after Transarterial Chemoembolization in Hepatocellular Carcinoma.

BACKGROUND/AIMS: To investigate the predictive factors for complete response (CR) and recurrence after CR in patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). METHODS: Among 691 newly diagnosed HCC patients, 287 were treated with TACE as a first therapy. We analyzed the predictive factors for CR, recurrence after CR, and overall survival (OS). RESULTS: Eighty-one patients (28.2%) achieved CR after TACE, and recurrence after CR was detected in 35 patients (43.2%). In multivariate analyses, tumor size (≤5 cm) and single nodularity were predictive factors for CR, with hazard ratios (HRs) of 0.35 (p=0.002) and 0.41 (p<0.001), respectively. Elevated serum α-fetoprotein (AFP) (>20 ng/mL) level and multinodularity exhibited significant relationships with recurrence after CR, with HRs of 2.220 (p=0.026) and 3.887 (p<0.001), respectively. Tumor size (>5 cm), multinodularity, elevated serum AFP (>20 ng/mL) level, Child-Turcotte-Pugh score (B and C), and portal vein thrombosis were significant factors for OS. CONCLUSIONS: In patients treated with TACE as a first therapy, tumor size (≤5 cm) and single nodularity were predictive factors for CR, and multinodularity and elevated serum AFP (>20 ng/mL) levels were predictive factors for recurrence after CR. These factors were also significant for OS.

Loeffler's Syndrome Induced by Ingestion of Urushiol Chicken.

Eosinophilic lung diseases are heterogeneous disorders characterized by varying degrees of pulmonary parenchyma or blood eosinophilia. Causes of eosinophilic lung diseases range from drug ingestion to parasitic or fungal infection as well as idiopathic. The exact pathogenesis of eosinophilic lung disease remains unknown. Urushiol chicken can frequently cause allergic reactions. Contact dermatitis (both local and systemic) represents the most-common side effect of urushiol chicken ingestion. However, there has been no previous report of lung involvement following urushiol chicken ingestion until now. A 66-year-old male was admitted to our hospital with exertional dyspnea. Serial chest X-ray revealed multiple migrating infiltrations in both lung fields, with eosinophilic infiltration revealed by lung biopsy. The patient had ingested urushiol chicken on two occasions within the 2 weeks immediately prior to disease onset. His symptoms and migrating lung lesions were resolved following administration of oral corticosteroids.

A Case of the Drug Reaction with Eosinophilia and Systemic Symptom (DRESS) Following Isoniazid Treatment.

The drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a severe adverse drug-induced reaction which includes a severe skin eruption, fever, hematologic abnormalities (eosinophilia or atypical lymphocytes) and internal organ involvement. The most frequently reported drug was anticonvulsants. The diagnosis of DRESS syndrome is challenging because the pattern of cutaneous eruption and the types of organs involved are various. The treatments for DRESS syndrome are culprit drug withdrawal and corticosteroids. Here we report a 71-year-old man with skin eruption with eosinophilia and hepatic and renal involvement that appeared 4 weeks after he had taken anti-tuberculosis drugs (isoniazid, ethambutol, rifampicin, and pyrazinamide), and resolved after stopping anti-tuberculosis drugs and the administration of systemic corticosteroids. DRESS recurred after re-challenging isoniazid, we identified isoniazid was causative drug.
