There has been a sharp increase in the number of obese people worldwide thanks to modern prosperity in accordance with rapid industrialization and economic development. Recently, bariatric surgery has been applied actively to extremely obese patients (BMI>35 kg/m2) and presented as an alternative solution to provide not only weight loss but also a treatment for metabolic diseases such as diabetes mellitus, hypertension, and hyperlipidemia. Gastroesophageal reflux disease (GERD) is one of the most important diseases in morbidly obese patients, and many patients suffer from symptoms like epigastric pain, regurgitation, and dry cough. However, such symptoms are easy to be overlooked and studies on GERD are scarce in relation to bariatric surgery. In morbidly obese patients, high abdominal pressure leads to a pressure gradient between esophagus and stomach. This induces a hiatal hernia causing a greater likelihood of GERD. Many studies in regards to GERD were made after bariatric surgery (sleeve gastrectomy, Roux-en-Y gastric bypass, and gastric band), and various results have been presented. Studies should be carried out on pre-operative diagnosis of GERD, choice of operative method, and improvement of symptoms after the operation. Research is also needed upon bariatric operation in patients with uncontrolled GERD.

Purpose: This study was conducted to evaluate clinical usefulness by evaluating the marginal bone resorption and survival rate of an implant with a taper straight type SLA surface domestically available on the market recently. Materials and methods: 40 implants satisfying the including criteria were observed for one year of 125 implants of 83 adult men and women who had KISPLANT® implanted from August 2016 to December 2019 at the Department of Periodontology, Chonnam National University Dental Hospital. The marginal bone level was measured on periapical radiographs taken initially and 1 year later and we analyzed implant survival and success rates. A t-test was used for the analysis of the association between the marginal bone resorption and the severity of periodontitis, supportive periodontal therapy, the inserted site, the cause of extraction, immediate placement, and systemic disease. Results: After 1 year of loading, the mesial bone resorption was 0.74 ± 1.07 mm, and the distal bone resorption was 0.53 ± 1.04 mm. The marginal bone resorption of 2 mm or more occurred at 3 implants out of 40 implants after 1 year, so the success rate of implant was 92.5% and survival rate was 100%. There was a significant difference in mesial marginal bone resorption according to the inserted site and no significant differences were found between marginal bone resorption and the other factors. Conclusion As a result of marginal bone resorption, success rate, and survival rate in this study, we found little marginal bone resorption and high survival and success rate. It can be concluded that they represent excellent clinical results.

The nutritional support of acutely ill patients is very important and early enteral nutrition is recommended. Feeding via the nasogastric route is used widely for its ease of access if the patient cannot maintain volitional food intake. If the position of the tip or side holes of the nasogastric tube (NGT) is above the gastroesophageal junction, there is the possibility of retention and solidification of the administered enteral feeding formula in the esophagus. Therefore, the tip of the NGT should be checked carefully; a chest radiograph to confirm its position can be considered, especially in patients with a higher risk of aspiration and gastroesophageal reflux. In addition, careful consideration of the risk factors that can trigger esophageal obstruction is required when feeding patients in the intensive care unit. This paper describes two unusual cases of esophageal obstruction caused by the solidification of residue of an enteral feeding formula.

BACKGROUND: The immune thrombocytopenia (ITP) criteria were newly standardized by the International Working Group. Thus, we analyzed the natural course of childhood chronic ITP to predict the prognosis based on the revised criteria. METHODS: The medical records of children with chronic ITP from May 2000 to February 2013 in our institute were reviewed. RESULTS: Forty-seven children with chronic ITP who were not undergoing corticosteroid therapy were included. Their initial platelet count was 23+/-25x10(9)/L, and age at diagnosis was 6.3+/-4.1 years. The follow-up period was 5.4+/-3.7 years. Among them, 44.7% (21/47) showed spontaneous remission and maintained a platelet count > or =100x10(9)/L. And 66.0% (31/47) maintained a platelet count > or =50x10(9)/L until the last follow-up date. The time periods required for the platelet count to be maintained > or =50x10(9)/L and > or =100 x10(9)/L were 3.1+/-2.7 and 3.6+/-2.7 years. Age at diagnosis in the > or =50x10(9)/L group (5.7+/-4.4 years) was significantly lower than the age at diagnosis in the <50x10(9)/L group (7.4+/-3.3 years) (P=0.040). And follow-up period was the factor influencing prognosis between the > or =100x10(9)/L group and <50x10(9)/L group (P=0.022). CONCLUSION: Approximately 45% of children with chronic ITP recovered spontaneously about 3-4 years after the diagnosis and 2/3 of patients maintained a platelet count > or =50x10(9)/L, relatively safe state. Age at diagnosis of ITP and follow-up period were the factors influencing prognosis in this study.

Gastrojejunocolic fistula is a rare condition after gastrojejunostomy. It is severe complications of gastrojejunostomy, which results an inadequate resection or incomplete vagotomy during peptic ulcer surgery. The symptoms are diarrhea, upper abdominal pain, bleeding, vomiting and weight loss. A 55-year-old man with chronic diarrhea and weight loss for 6 months visited Dankook University Hospital. The patient had received a truncal vagotomy and gastrojejunostomy for duodenal ulcer obstruction 15 years previously. The patient underwent gastroscopy and upper gastrointestinal series evaluations, which detected the gastrojejunocolic fistula. After improving of malnutrition, an exploratory laparotomy was undertaken, which revealed that the gastrojejunostomy site and the T-colon formed adhesion and fistula. En block resection of the distal stomach and T-colon included the gastrojejunocolic fistula, and Roux-en-Y gastrojejunostomy was performed. Recovery was uneventful and the patient remained well at the follow-up. We report a gastrojejunocolic fistula, which is a rare case after gastrojejunostomy.

Purpose: This study aimed to compare treatment options and outcomes based on peritoneal cancer index (PCI) among patients with peritoneal metastasis (PM) of advanced gastric cancer (AGC). Methods: Between January 2016 and July 2019, clinicopathological data of patients with AGC diagnosed with PM were reviewed. Different treatment methods were performed according to the PCI score: (1) group A (PCI ≤ 13) received cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with postoperative intraperitoneal (IP) and systemic chemotherapy (n = 29), while (2) group B (PCI > 13) received IP chemotherapy with systemic chemotherapy (n = 22). Results: Clinical outcomes of 51 patients at the Dankook University Hospital were reviewed. Group A had a significantly lower mean PCI score (9.8 ± 6.9 vs. 32.6 ± 7.1, P < 0.01) than group B, with 25 patients (86.2%) achieving complete cytoreduction. Complications occurred in 16 patients (31.4%), none of who suffered mortality (group A: 11 patients, 37.9% vs. group B: 5 patients, 22.7%; P = 0.25). Among the morbidity, 5 cases (17.2%) and 2 cases (9.1%) exhibited a Clavien-Dindo grade greater than III in groups A and B, respectively (P = 0.04). Groups A and B had an overall median survival time of 34.0 and 16.0 months, respectively (P = 0.03). Conclusion Patients with PM of AGC received different treatments according to their PCI score. When accompanied with careful patient selection, our approach may be considered an acceptable option for the treatment of PM of AGC.

A 3-month-old male infant was transferred to our hospital due to bicytopenia. His bone marrow biopsy showed irregular bony trabeculae with cartilaginous core, which was consistent with osteopetrosis. In the genetic test, c.242del (p.Pro81Argfs*85) in TCIRG1 was found to be homozygotic, thus he was diagnosed with malignant infantile osteopetrosis. At 6 months of age, he received double-unit umbilical cord blood transplantation (UCBT) with the conditioning regimen including busulfan, cyclophosphamide, and rabbit anti-thymocyte globulin. Initially, single UCB was infused to the patient, but the post infusion viability of the UCB was unexpectedly low. Thus, another UCB was additionally infused. Cyclosporine and mycophenolate mofetil were used for graft-versus-host disease (GVHD) prophylaxis. Neutrophils and platelets were engrafted on day +13 and +33, respectively. With engraftment, he showed overall grade 4 acute GVHD involving the skin and gut, which was refractory to corticosteroids. Despite treating with low-dose weekly methotrexate (10 mg/m2) and oral beclomethasone, his symptoms persisted. After treating with ruxolitinib 2.5 mg/day for 2 weeks, and 5 mg/day thereafter, his diarrhea stopped in 2 weeks and his skin symptoms gradually improved over 3 months. The short tandem repeats showed 100% donor chimerism at 1 and 3 months after UCBT. Currently, 4 months after UCBT, he is 10 months old. The oral prednisolone has been tapered to 0.6 mg/kg/day, and the dose of ruxolitinib was decreased to 2.5 mg/day without recurrence of GVHD. We plan to taper off the immunosuppressive agents if his GVHD symptoms do not recur.

Background: Body weight is a modifiable demographic factor. Although the association of body mass index (BMI) categories with sudden cardiac death was reported, dynamic changes of BMI and the risk of cardiac arrest remain unknown. This study aimed to evaluate the association between the out-of-hospital cardiac arrest (OHCA) occurrence within a year and the percent changes of BMI preceding the OHCA. Methods: This population-based nested case-control study used the National Health Insurance Service Data of Korea. In all, 24,465 patients with non-traumatic OHCA between 2010 and 2018, who underwent national health check-up twice (one within a year and the other within 2–4 years before OHCA) and 32,434 controls without OHCA, were matched for age and sex. The association between the risk of OHCA and BMI percent change stratified by sex was investigated. Results: All the BMI percent changes of ≥ 5% significantly increased the OHCA occurrence with a reverse J-shaped association. Compared to individuals with a stable weight, those with severe (> 15%) BMI decrease had the highest odds ratio (OR) of 4.29 (95% confidence intervals [CIs], 3.72–4.95) for OHCA occurrence followed by those with moderate (10–15%) weight loss (OR, 2.80; 95% CI, 2.55–3.08) and those with severe (> 15%) weigh gain (OR, 2.24; 95% CI, 1.96–2.57), respectively. The impact of weight loss on the cardiac arrest occurrence was more prominent in men, while the impact of weight gain was more prominent in women. Conclusion Significant weight changes increase the risk of OHCA within a year with a reverse J-shaped association. Significant weight loss might be a warning sign for OHCA especially for men.
