Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS) using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE) project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

The demand for uterine preservation in pelvic reconstructive surgery for uterovaginal prolapse is steadily increasing, and several procedures have been introduced, such as sacrospinous hysteropexy, uterosacral hysteropexy, sacrohysteropexy, and hysteropectopexy. However, the benefits and risks of uterine-preserving surgeries are not well understood. This review discusses the current evidence surrounding uterine-preserving surgery for uterovaginal prolapse repair. This may help surgeons and patients have a balanced discussion on how and on whom to perform uterine-preserving surgery.

Purpose: The aim of this study was to assess the epidemiologic and clinical features of maternal Group B Streptococcus (GBS) colonization in vagina during their third trimester. Methods: This study included 644 pregnant women who had undergone GBS culture test in their third trimester in 2018. We collected data from the primary level of care maternity hospital through the retrospective chart review. We compared patients’ demographics, maternal obstetrical complications and neonatal adverse events between GBS positive (n=41) and GBS negative (n=603) groups. To find out clinical predictors of GBS positive result, univariable chi-square test and multivariable logistic regression analysis were applied. Results: The colonization rate of GBS in maternal vagina was 6.4% in their third trimester. GBS positive group showed significant association with the third trimester anemia (hemoglobin level <10.5 g/dL) (p=0.013) and oligohydramnios (p=0.024; odds ratio, 7.32; 95% confidence interval, 1.28–41.31). All specimens were susceptible to penicillin G and cephalosporin. The antibiotic resistance to both erythromycin and clindamycin was 31%. Conclusion The colonization rate of GBS in maternal vagina was 6.4% and third trimester maternal anemia was associated with the GBS carrying status.

This review aimed to summarize the complications and surgical outcomes of robot-assisted sacrocolpopexy. Nineteen original articles on 1,440 robotic sacrocolpopexies were reviewed, and three systematic reviews and meta-analyses were summarized in terms of intraoperative, perioperative, postoperative, and/or surgical outcomes. Robotic sacrocolpopexy has demonstrated low overall complication rates and favorable surgical outcomes. Nevertheless, long-term follow-up outcomes regarding objective and/or subjective prolapse recurrence, reoperation rates, and mesh-related complications remain unclear. Further research is required to demonstrate whether the robotic approach for sacrocolpopexy is feasible or can become the modality of choice in the future when performing sacrocolpopexy.

OBJECTIVE: This study aimed to compare perioperative and postoperative morbidity of older and younger women undergoing sacrocolpopexy (SCP). METHODS: A retrospective study included 271 patients who underwent laparotomic SCP for symptomatic pelvic organ prolapse from November 2008 to June 2013 at our institution. By the review of medical records, perioperative and postoperative data including the length of the surgery, estimated blood loss, blood transfusion, the length of hospital stay, wound complications and febrile morbidity were collected. In addition, cardiovascular, pulmonary, gastrointestinal, genitourinary, or neurological adverse events were retrieved. The need for an indwelling urinary catheter or performance of clean intermittent self-catheterization, mesh erosion rate and the number of days required for each were included in the postoperative outcomes. For the outcome variable analyzed in this study, the patients was dichomotized into women aged 65 and older and those younger than 65. RESULTS: One hundred and thirty-five (49.8%) patients were younger than 65 and 136 (50.2%) were aged 65 and older. Older women had higher body mass index, vaginal parity and prior surgery for hysterectomy than younger women (P<0.05). And older women had higher baseline comorbidities, such as hypertension, diabetes, cardiac disease (P<0.05), and their American society of Anesthesiologist class was higher (P<0.001). In the perioperative and postoperative complication, older group showed no differences in most of the operation-related complication rates, but gastrointestinal complication rate. Also, mesh erosion rate was not found to be significantly different between the two groups at the last visit. CONCLUSION: Older women undergoing laparotomic SCP have similar perioperative and postoperative morbidities as younger women, suggesting surgeons can counsel older and younger women similarly in terms of operative risks.

OBJECTIVE: Despite the good prognosis of borderline ovarian tumors (BOTs), a few BOT patients experience the relapse of disease, either borderline or malignant. However, the risk of recurrence of BOTs is somewhat controversial. We intended to find out the specific characteristics and prognosis of the recurrence of BOTs. METHODS: Between 1995 and 2012, 130 women were diagnosed with BOTs at a single institution. Eleven patients diagnosed and treated for the recurrence of BOTs including seven cancerous and four borderline relapses were included for the analysis in this retrospective study. Clinicopathological characteristics and surgical procedures as well as follow-up data with overall survival were assessed. Statistical analyses was performed using the chi2 test, t-test and log-rank test with Cox regression. RESULTS: One hundred and thirty patients with mean follow-up of 65.8 months were evaluated, of whom half were below 40 years old at their first diagnosis of BOTs. Among 11 recurrent cases (8.5%), 7 cancerous transformations (5.4%) and 4 borderline recurrences (3.1%) were detected with median time of 6 and 71 months after the primary surgery, respectively. Nine out of 11 recurrences were happened at their equal or below 40-years-old age at the primary diagnosis (P=0.027). Also, all 7 cancerous relapses arose from premenopausal women of median age of 35 years old. Twenty (15%) patients had laparoscopic surgery and they were all treated conservatively. Among those 20, 5 were suffered from relapse of BOTs and laparoscopic approach was proved to be a significant risk factor for disease relapse in our study (P=0.013). Although laparoscopic surgery was revealed had meaningful influence on disease free survival (P=0.024), it was not significant on overall survival (P=0.226). CONCLUSION: Laparoscopic conservative surgery for BOTs can be accepted under close follow-ups. And younger patients should be followed for long period to evaluate recurrence.

Extramammary Paget’s disease (EMPD) is a rare malignant neoplasm of the apocrine sweat gland-bearing skin in the genital, perianal, or axillary region. EMPD may simultaneously occur in the genital and both sides of the axillae, termed as “triple EMPD,” which was first reported by Kawatsu and Miki in 1971. Since its first description, 28 Japanese and only 4 Caucasian cases of triple EMPD have been reported. Here, we present the first Korean case of triple EMPD in the groin and bilateral axillae in a 46-year-old female patient whose axillary lesions appeared consistent with seborrheic keratosis. This case emphasizes the need to consider EMPD in differential diagnosis when evaluating acanthotic axillary lesions since it can mimic benign lesions.

Objective: To identify the factors associated with unsuccessful pessary fitting and reasons for pessary discontinuation in Korean women with pelvic organ prolapse (POP). Methods: The medical records of 234 patients who underwent pessary fitting for the management of symptomatic POP were retrospectively reviewed. A ring pessary with or without support was used. Successful pessary fitting was defined as the ability to wear a pessary for 2 weeks without any discomfort. Factors associated with unsuccessful pessary fitting were determined using a multivariable logistic regression analysis. A Kaplan-Meier survival curve was obtained to examine the probability of continuing pessary use over the follow-up period. The reasons for the discontinuation of pessary were identified. Results: Two-hundred-and-twenty-five women were included in the analysis. The rate of unsuccessful pessary fitting was 40%. Prior hysterectomy (odds ratio [OR], 4.13; 95% confidence interval [CI], 1.81-9.42) and POP quantification stage III-IV (OR, 2.49; 95% CI, 1.28-4.85) were independent risk factors for unsuccessful pessary fitting. Among the patients with successful pessary fitting, the median time to discontinuation of pessary use was 4 years. The most common causes of discontinued use were vaginal erosion (45.3%) and urinary incontinence (26.5%). Conclusion Patients with a history of hysterectomy and advanced-stage POP are at risk for an unsuccessful fitting of the ring pessary. Vaginal erosion is the main reason for discontinued use among patients with successful pessary fitting.

BACKGROUND: Interictal spikes in gelastic epilepsy-hypothalamic hamartoma syndrome are mainly in the fronto-temporal area. Current source analysis of the interictal spikes has not been done enough. We tried the current source analysis in 2 patients with gelastic epilepsy-hypothalamic hamartoma syndrome using both of the discrete and distributed models. METHODS: Twenty 1 sec epochs including the negative peak of the spikes, were selected from one or two electroencephalographic recordings respectively in each patient. These 20 epochs were averaged into a single spike. The current dipole sources of the averaged spike were analyzed and located on a spherical head model. The current source density of the negative peak point of the averaged spike was located on the Talairach human brain map. RESULTS: The current dipole sources were in the right subcallosal gyrus, or the right or left anterior cingulate gyri. The current source density was distributed in the bilateral medial frontal area including the anterior cingulate gyri. CONCLUSIONS: The interictal spikes of patients with gelastic epilepsy-hypothalamic hamartoma syndrome may be generated by the current sources located in the bilateral medial frontal area.

Background: Rapid revascularization is the key to better patient outcomes in ST-elevation myocardial infarction (STEMI). Direct activation of cardiac catheterization laboratory (CCL) using artificial intelligence (AI) interpretation of initial electrocardiography (ECG) might help reduce door-to-balloon (D2B) time. To prove that this approach is feasible and beneficial, we assessed the non-inferiority of such a process over conventional evaluation and estimated its clinical benefits, including a reduction in D2B time, medical cost, and 1-year mortality. Methods: This is a single-center retrospective study of emergency department (ED) patients suspected of having STEMI from January 2021 to June 2021. Quantitative ECG (QCG™), a comprehensive cardiovascular evaluation system, was used for screening. The non-inferiority of the AI-driven CCL activation over joint clinical evaluation by emergency physicians and cardiologists was tested using a 5% non-inferiority margin. Results: Eighty patients (STEMI, 54 patients [67.5%]) were analyzed. The area under the curve of QCG score was 0.947. Binned at 50 (binary QCG), the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 98.1% (95% confidence interval [CI], 94.6%, 100.0%), 76.9% (95% CI, 60.7%, 93.1%), 89.8% (95% CI, 82.1%, 97.5%) and 95.2% (95% CI, 86.1%, 100.0%), respectively. The difference in sensitivity and specificity between binary QCG and the joint clinical decision was 3.7% (95% CI, −3.5%, 10.9%) and 19.2% (95% CI, −4.7%, 43.1%), respectively, confirming the non-inferiority. The estimated median reduction in D2B time, evaluation cost, and the relative risk of 1-year mortality were 11.0 minutes (interquartile range [IQR], 7.3–20.0 minutes), 26,902.2 KRW (22.78 USD) per STEMI patient, and 12.39% (IQR, 7.51–22.54%), respectively. Conclusion AI-assisted CCL activation using initial ECG is feasible. If such a policy is implemented, it would be reasonable to expect some reduction in D2B time, medical cost, and 1-year mortality.
