Achalasia and gastroesophageal reflux disease (GERD) are on opposite ends of the spectrum of lower esophageal sphincter dysfunction. Heartburn is the main symptom of GERD. However, heartburn and regurgitation are frequently observed in patients who have achalasia. The diagnosis of achalasia might be delayed because these symptoms are misinterpreted as gastroesophageal reflux. Here, we reviewed the clinical characteristics of patients with the erroneous diagnosis of GERD who actually had untreated achalasia.

This review focuses on the current options for fertility preservation in patients with high risk of premature ovarian failure. Available cryopreservation options include embryo cryopreservation, oocyte cryopreservation, and ovarian tissue cryopreservation. Ovarian tissue cryopreservation and transplantation has been tried for some time in animals, but only recently successful pregnancy and livebirth in human has been reported. Options of developing follicles and restoring fertility after ovarian tissue cryopreservation are autotransplantation, xenotransplantation, and tissue culture. This review discusses the merits and faults of each option and future directions for developing and standardizing the ovarian tissue cryopreservation and transplantation procedure, systemically covering previously published data.

Intestinal tuberculosis is an infection of the gastrointestinal tract by the Mycobacterium tuberculosis complex. To the best of our knowledge, solitary intestinal tuberculosis accompanied by intestinal obstruction, particularly in the middle of the small intestine, is extremely rare. We report a case of solitary jejunal tuberculosis in a 49-year-old man with no underlying disease. He was admitted a few days after the onset of diffuse abdominal discomfort. Upon evaluation, we initially considered a malignancy of the distal jejunum with ileus due to the presence of a mass. Therefore, he underwent laparoscopic resection of the small bowel. Unexpectedly, the histologic specimen showed a chronic caseating granulomatous lesion with acid-fast bacilli. Ultimately, he was diagnosed with solitary jejunal tuberculosis. He was successfully treated with anti-tuberculosis drugs without any complications.

OBJECTIVES: Previous studies examining the association between osteoporosis (OP) and hearing loss (HL) have shown conflicting results. The objective of the present study was to examine the association between hearing impairment and OP in postmenopausal women, using appropriate statistical analyses. METHODS: Total 1,009 participants were included in the current study. The propensity score matched (PSM) cohort was defined as the cohort including participants diagnosed with OP and participants without OP. Three statistical models were developed where model 1 was unadjusted, model 2 included age, and model 3 included age, body mass index, alcohol intake, smoking habit, diabetes mellitus, hypertension, high density lipoprotein cholesterol, triglyceride level, vitamin D, and alkaline phosphatase. RESULTS: There were 776 and 233 participants in the groups diagnosed without and with OP, respectively. For propensity score matching, 233 pairs were selected from the 776 participants without OP. In the total cohort, using statistical models 2 and 3, no significant difference in the four hearing thresholds was identified between the 2 groups. Logistic regression indicated that, in model 3, participants with OP had a 1.128 (P=0.323) increased risk HL. A significant HL risk was not observed in participants with OP. Using statistical model 3, there were no significant associations among lumbar spine or femoral neck T-scores and changes in the hearing thresholds. In the PSM cohort, statistical models also showed similar results. CONCLUSION: The current study did not demonstrate and association between bone mineral density and hearing impairment in the study population of postmenopausal Korean women.

Necrotizing fasciitis (NF) is defined as rapidly progressive necrosis of subcutaneous fat and fascia. Although NF of the face is rare, its mortality rate is nearly 30%. It usually originates from dental infection and can lead to involvement of the neck, mediastinum, and chest wall. Complications resulting from pre-existing systemic diseases can increase the mortality rate. Known complication factors for NF include diabetes, malnutrition, advanced age, peripheral vascular disease, renal failure, and obesity. Here, we report a case of NF originating from dental infection in an 88-year-old woman already diagnosed with hypertension, thoracic aortic aneurysm, and renal diseases. Such conditions limited adequate surgical and antibiotic treatment. However, interdisciplinary treatment involving multiple departments was implemented with good results.

BACKGROUND/AIMS: GC7101, an extract of Lonicera Flos, is a novel developing drug for reflux esophagitis and functional dyspepsia. However, the drug's exact pharmacological mechanism of action remains unclear. This study assessed the effects of GC7101 on gastrointestinal (GI) motor function. METHODS: We used male guinea pigs to evaluate the effects of GC7101 on GI motility. The contraction of antral circular muscle in the presence of different doses of GC7101 was measured in a tissue bath. The prokinetic effects of GC7101 were tested using the charcoal transit assay from the pylorus to the most distal point of migration of charcoal mixture. To clarify the mechanism of action of GC7101, atropine, dopamine and the selective 5-hydroxytryptamine 4 receptor antagonist, GR113808 were used. RESULTS: The maximal amplitude of circular muscle contraction was induced by 5 mg mL(-1) GC7101. The area under the curve of contraction was significantly increased at 5 mg mL(-1) GC7101. Addition of 10(-6) M atropine, 10(-8) M dopamine or 10(-7) M GR 113808 to GC7101 5 mg mL(-1) decreased the amplitude and area under curve compared to GC7101 5 mg mL(-1) alone. GC7101 accelerated GI transit in a dose dependent manner except 100 mg kg(-1). Delayed GI transit caused by atropine, dopamine and GR 113808 was restored by GC7101 50 mg kg(-1). CONCLUSIONS: GC7101, an extract of Lonicera Flos, exerts a gastric prokinetic effect in guinea pig through cholinergic, antidopaminergic and serotonergic mechanisms. Therefore, GC7101 might be a novel drug for the treatment of functional dyspepsia.

BACKGROUND/AIMS: Esophageal eosinophilia occurs in many conditions, including eosinophilic esophagitis (EoE) and proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE), which have been increasingly recognized in Western countries. There have been only a few reports in Korea. Here, we evaluated the clinical and endoscopic characteristics of patients with esophageal eosinophilia from our experience. METHODS: Nineteen patients were diagnosed with esophageal eosinophilia based on typical symptoms, endoscopic features, esophageal eosinophilia with ≥15 eosinophils/high power field, and response to medication by PPI. Symptoms, endoscopic and pathological findings were evaluated. RESULTS: Of the 19 patients, 2 patients were diagnosed with EoE, 7 patients were diagnosed with PPI-REE, and 10 patients were undetermined due to loss to follow-up. Among these 19 patients, dysphagia was present in 11, and heartburn, dyspepsia and reflux in 8. Sixteen patients had common endoscopic features, such as longitudinal furrows, concentric rings, strictures, and white plaques; however, 3 patients had normal findings. Nine patients underwent endoscopy at the time of follow-up. Two patients had complete resolution, and 3 had partial resolution. However, 4 patients showed no endoscopic changes. All patients showed symptom improvements. CONCLUSIONS: The clinical and endoscopic characteristics of both groups in Korea were undistinguishable. However, after treatment, endoscopic findings were different between the two groups. Large-scale studies are warranted to confirm our findings.

BACKGROUND/AIMS: Proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE) is a newly recognized form of eosinophilic esophagitis (EoE) that responds to PPI therapy. It remains unclear whether PPI-REE represents a subphenotype of gastroesophageal reflux disease, a subphenotype of EoE, or its own distinct entity. The aim was to evaluate the clinicopathologic features of PPI-REE. METHODS: Six patients were diagnosed with PPI-REE based on symptoms, endoscopic abnormalities, esophageal eosinophilia with > or =15 eosinophils/high-power field, and a response to PPI treatment. Symptoms and endoscopic and pathological findings were evaluated. RESULTS: The median follow-up duration was 12 months. Presenting symptoms included dysphagia, heartburn, chest pain, foreign body sensation, acid reflux, and sore throat. All patients had typical endoscopic findings of EoE such as esophageal rings, linear furrows, nodularity, and whitish plaques. Three patients had a concomitant allergic disorder, and one had reflux esophagitis. Four patients exhibited elevated serum IgE, and five had positive skin prick tests. All patients experienced symptomatic resolution within 4 weeks and histologic resolution within 8 weeks after starting PPI therapy. There was no symptomatic recurrence. CONCLUSIONS: PPI therapy induced rapid resolution of symptoms and eosinophil counts in patients with PPI-REE. Large-scale studies with long-term follow-up are warranted.

BACKGROUND: Previous studies suggest that habitual exercise can improve skeletal mitochondrial function; however, to date, the association between exercise and mitochondrial function in peripheral leukocytes has not been reported. The aim of this study was to evaluate the relationship between regular exercise and mitochondrial function by measuring leukocyte mitochondrial DNA (mtDNA) copy number in postmenopausal women. METHODS: This cross-sectional study included 144 relatively healthy, non-diabetic, non-smoking, postmenopausal women. Clinical parameters, including anthropometric measurements and cardio-metabolic parameters, were assessed. Regular exercise was defined as at least 150 minutes per week of moderate-intensity activity, or an equivalent combination of moderate and vigorous-intensity activity, over a duration of at least 6 months. Leukocyte mtDNA copy numbers were measured using real-time polymerase chain reaction assays, and these were normalized to the β-globin copy number to give the relative mtDNA copy number. RESULTS: The mtDNA copy number of peripheral leukocytes was significantly greater in the exercise group (1.33±0.02) than in the no exercise group (1.05±0.02, P<0.01). Stepwise multiple regression analysis showed that regular exercise was independently associated with mtDNA copy number (β=0.25, P<0.01) after adjusting for the variables age, body mass index, waist-to-hip ratio, systolic and diastolic blood pressure, homeostasis model assessment of insulin resistance value, and levels of high-density lipoprotein cholesterol, triglycerides, and homocysteine. CONCLUSION: Regular exercise is associated with greater leukocyte mtDNA copy number in postmenopausal women.

Twin pregnancies are at substantially higher risks for premature delivery than singleton pregnancies. This further increases their risk of perinatal and infant mortality. Recently there has been a marked increase in multiple pregnancies as a direct result of assisted reproductive technology. Cervical incompetency is a condition in which a pregnant woman's cervix begins to dilate and efface before her pregnancy has reached term. And multiple pregnancies and pregnancies by in vitro fertilization (IVF) have been increasing the risk of cervical incompetency. In twin pregnancy during preterm delivery, successful delayed-interval deliveries may improve the neonatal outcomes of the second fetus. We report a case of a delayed interval delivery in twin pregnancy of incompetent of cervix with an interval of 28 days after 3rd emergency cerclage.
