Achalasia is an esophageal motility disorder characterized by loss of esophageal peristalsis and impaired relaxation of the lower esophageal sphincter. Patients with achalasia often complain of persistent symptoms for several years before diagnosis. On the other hand, achalasia diagnosed as a sudden esophageal food impaction is uncommon, and no report has been issued on the diagnosis and successful treatment of achalasia in a 95-year-old patient. We report a case of achalasia diagnosed by high-resolution esophageal manometry and timed barium esophagography after food material removal by endoscopy in a 95-year-old woman who visited the hospital due to sudden esophageal food impaction and was successfully treated by endoscopic balloon dilatation.

Recently, amniotic fluid has gained attention as one of the potential sources for cell therapy and tissue engineering because it has characteristics of multipotent stem cells. However, current knowledge about what types of cells are naturally found in amniotic fluid is still limited. In this study, we aimed to investigate whether human amniotic fluid contains cells that have characteristics of respiratory cells. Samples of human amniotic fluid (5 mL per sample) obtained from amniocenteses were cultured with small airway growth medium (SAGM). Cells were grown until the third passage and the presence of type II alveolar cells were characterized by inverted microscopy, immunofluorescence, and reverse transcription polymerase chain reaction (RT-PCR). On inverted microscopy, cultured cells showed typical polygonal and cobblestone-like epithelial morphology. The morphology of cells was not changed after selection and passing. Immunofluorescence analysis demonstrated that the isolated cells stained positive for surfactant protein C (SPC), specific marker for type II alveolar cells. Cells also stained positive for TTF-1 protein but negative for CD 31 and vimentin. RT-PCR analysis of cells showed expression of SPC mRNA. This study has demonstrated that respiratory cells can be isolated and identified from human amniotic fluid cultured in SAGM medium. Our results may provide the basis for further investigations of amniotic fluid.

Early diagnosis of Borrmann type 4 advanced gastric cancer (AGC) is very important for improving the prognosis of AGC patients. Because there is no definite mass in most cases of Borrmann type 4 AGC, its accurate diagnosis via endoscopy requires an understanding of its pathogenesis and developmental process. Moreover, many people confuse linitis plastica (LP) type gastric cancer (GC), scirrhous GC, and Borrmann type 4 AGC. To distinguish each of these cancers, knowledge of their endoscopic and pathological differences is necessary, especially for LP type GCs in the developmental stage. In conclusion, diagnosis of pre-stage or latent LP type GC before progression to typical LP type GC requires the detection of IIc-like lesions in the fundic gland area. It is also crucial to identify any abnormalities such as sclerosis of the gastric wall and hypertrophy of the mucosal folds during endoscopy.

Amyotrophic lateral sclerosis is a rare disease. It is a fatal neurodegenerative disease characterized by progressive muscular paralysis reflecting degeneration of motor neurons which leads to muscle weakness and muscle wasting. Respiratory failure limits survival to 2-5 years after disease onset. Several clinical manifestations including dysphagia can result in reductions in both the quality of life and life expectancy. Dysphagia occurs at onset in about one third of case, although generally it occurs in later stage of the disease. Evaluation of dysphagia includes video-fluoroscopic swallow study, radiological esophagogram, flexible endoscopic examination, ultrasound examination, conventional manometry and electromyography. We report a case of amyotrophic lateral sclerosis in a 54-year-old man presenting oropharyngeal dysphagia which was diagnosed by high resolution esophageal manometry presenting abnormality of the upper esophageal sphincter.

A case of 42-year-oldI kidney transplant patient who developed invasive carcinama of the cervix after immunoauppresawe therepy is reported and the literature related to this diease is revuewed. The iatmgenic immunosuppresaionn renal transplantation recipients has been associated with increased incidence of malignancy in these patients. In particular, immunosuppressed women are al greater risk of developing cervical intraepithelial neoplasia and buman papillomavirus type 16 or 18 infection. So, all such individuals are required to receive periodic gynecologic examination before renal transplantation and at regular intervals thereafter so that the development of CIN may be diagnosed at an early Stage and treated effestively.

BACKGROUND/AIMS: Since the development of ambulatory esophageal pH monitoring test to diagnose gastroesophageal reflux disease (GERD), several parameters have been introduced. The aim of this study was to assess whether using the symptom index (SI), symptom sensitivity index (SSI), and symptom association probability (SAP), in addition to the DeMeester score (DS), would be useful for interpreting the Bravo pH monitoring test. METHODS: A retrospective study, which included 68 patients with reflux symptoms refractory to proton pump inhibitor (PPI) therapy who underwent a Bravo capsule pH test between October 2006 and May 2015, was carried out. Acid reflux parameters and symptom reflux association parameters were analyzed. RESULTS: The median percent time of total pH<4 and DS were 2.90% (interquartile range [IQR] 1.13–6.03%) and 11.10 (IQR 4.90–22.80), respectively. According to the analysis of the day-to-day variation in percent time of total pH<4 (r=0.724) and DS (r=0.537), there was a significant correlation between Day 1 and Day 2. The positive rate of Bravo test according to DS was 27 (39.7%). Although thirty patients experienced symptoms during the test, there were no significant differences of reflux parameters compared with other patients. In the symptom group, 7 patients (23.3%) were identified as having negative DS and an abnormal symptom-related index. There were no significant test-related complications. CONCLUSIONS: In addition to the analysis of traditional acid parameters of the Bravo capsule pH test, diagnosis of GERD, including reflux hypersensitivity, can be improved by performing an analysis of the symptom-reflux association and of the day-to-day variation.

BACKGROUND/AIMS: Gastric mucus should be removed before endoscopic examination to increase visibility. In this study, the effectiveness of premedication with pronase for improving visibility during endoscopy was investigated. METHODS: From April 2010 to February 2011, 400 outpatients were randomly assigned to receive endoscopy with one of four premedications as follows: dimethylpolysiloxane (DMPS), pronase and sodium bicarbonate with 10 minutes premedication time (group A, n=100), DMPS and sodium bicarbonate with 10 minutes premedication time (group B, n=100), DMPS, pronase and sodium bicarbonate with 20 minutes premedication time (group C, n=100), and DMPS and sodium bicarbonate with 20 minute premedication time (group D, n=100). One endoscopist, who was unaware of the premedication types, calculated the visibility scores (range, 1 to 3) of the antrum, lower gastric body, upper gastric body and fundus. The sum of the scores from the four locations was defined as the total visibility score. RESULTS: Group C showed significantly lower scores than other groups (p=0.002). Group C also had the lowest frequency of flushing, which was significantly lower than that of group D. Groups C and D had significantly shorter durations of examination than groups A and B. CONCLUSIONS: Using pronase 20 minutes before endoscopy significantly improved endoscopic visualization and decreased the frequency of water flushing.

A double pylorus, a fistulous communication between the gastric antrum and duodenal bulb, is a very rare anomaly. It appears as an acquired lesion in the majority of cases and mainly occurs in males with chronic obstructive pulmonary disease, chronic renal failure, chronic rheumatism, systemic lupus erythematosus, or diabetes. However, there are no previous reports of a double pylorus combined with diabetes mellitus in Korea. Recently we experienced a case of double pylorus caused by a peptic ulcer in 74-year-old man who had diabetes mellitus with complications. We report this case with a review of the literature.

A mixed adenoneuroendocrine carcinoma (MANEC) of the stomach is a rare disease entity that was first defined by the World Health Organization (WHO) classification (2010) for tumors of the digestive system. According to the WHO classification (2010), MANEC is referred to as a tumor with both neuroendocrine and non-neuroendocrine neoplasms; each component of the tumor should be at least 30%. On the other hand, this cut-off value lacks clinical evidence and does not explain the characteristics and heterogeneity of this tumor. A 66-year-old male diagnosed with early gastric cancer (EGC) at a community hospital was referred to the Kosin University Gospel Hospital for further evaluation of gastric cancer. Esophagogastroduodenoscopy and EUS performed at the Kosin University Gospel Hospital revealed a sub-mucosal tumor-like component. In addition, a re-biopsy revealed a neuroendorine tumor at different depths of the same tumor. The final pathologic-diagnosis through surgery revealed a mixed neuroendocrine-non-neuroendocrine neoplasm, which is inconsistent with the definition of MANEC. Clinicians should consider EUS when a tumor has atypical endoscopic findings, even if EGC has already been diagnosed.
