PURPOSE: Total prolapse of internal hemorrhoids around the entire anal circumference still remains as a challenging problem. Whitehead's circumferential hemorrhoidectomy is one of the surgical options. To elucidate efficacy of Whiteheads operation, we analyzed the surgical outcomes of Whiteheads operation. METHODS: The medical records of 165 consecutive patients who underwent Whiteheads operation for end-stage hemorrhoids were retrospectively reviewed. The mean operation time, the mean blood loss, and the mean hospital stay were examined. Also the types of complications were identified. All patients were followed for extended periods and in May 2003 they were asked to appraise their satisfaction (mean follow-up duration was 45.5 months, 12~93 month range). RESULTS: The mean operation time was 21.5+/-5.3 minutes, the mean blood loss was 50.5+/-22.0 cc, and the average hospital stay was 5.5+/-1.5 days. Early postoperative complications were fecal incontinence (60.6%) and voiding difficulty (53.3%). These problems were spontaneously resolved within 2 weeks. Pain was the most difficult problem, and all patients required a parenteral opioid for relief of pain. The only late complication was anal stenosis. Objectively, anal stenosis was found in 66 patients; however, 22 patients (13.3%) complained of defecation difficulty. Among them, only 4 patients required surgical treatment. The average score of satisfaction according to the patients themselves was 4.0+/-2.2, 0 being no satisfaction and 5 being complete satisfaction. CONCLUSIONS: The Whitehead operation, if performed properly for the selected patients, still remains as one of the best surgical options for end-stage hemorrhoids.

BACKGROUND: Antimicrobial resistance (AMR) is an issue not only with regard to public health, but also in terms of economic impact. AMR surveillance has mainly been carried out in general hospitals, and not in nursing hospitals. This study was conducted to investigate the AMR rate for bacterial strains isolated from nursing hospital samples.METHODS: Antimicrobial susceptibility testing (AST) results from a total of 23,518 bacterial isolates recovered from clinical specimens taken in 61 nursing hosals were analyzed. AST was conducted using Vitek 2 with AST cards specific for the bacterial strains.RESULTS: A total of 19,357 Gram-negative and 4,161 Gram-positive bacterial strains were isolated. Pseudomonas aeruginosa (n=6,384) and Escherichia coli (n=5,468) were the most prevalent bacterial species and, among Gram-positive bacteria, Staphylococcus aureus (n=1,565) was common. The AMR rate was high for the following strains: cefotaxime-resistant Klebsiella pneumoniae, 77.4%; cefotaxime-resistant E. coli, 70.6%; imipenem-resistant Acinetobacter baumannii, 90.3%; imipenem-resistant P. aeruginosa, 49.3%; oxacillin-resistant S. aureus, 81.1%, penicillin-resistant Enterococcus faecalis, 44.8%, and vancomycin-resistant Enterococcus faecium, 53.5%. AMR rate change varied by bacterial species and antimicrobial drug.CONCLUSION: AMR rates of major pathogens from nursing hospitals were higher than those from general hospitals with the exception of imipenem-resistant A. baumannii. Continuous monitoring and infection control strategies are needed.

BACKGROUND: The purpose of this study was to analyze factors related to screening for diabetic retinopathy in elderly diabetic patients.METHODS: This study included 682 elderly diabetic patients aged older than 65 years who answered the question “Have you undergone an eye examination in the last year?” from the Sixth Korea National Health and Nutrition Examination Survey 2013–2015. Data were analyzed using multiple logistic regression to identify the relationship between screening for diabetic retinopathy in elderly diabetic patients and related factors.RESULTS: Among the study population, 493 patients (73.3%) did not undergo eye examinations in the last year. Age ≥80 years (odds ratio [OR], 2.250; 95% confidence interval [CI], 1.014–4.992), current smoking (OR, 2.006; 95% CI, 1.018–3.953), poor subjective health status (OR, 0.457; 95% CI, 0.242–0.863), history of stroke (OR, 0.479; 95% CI, 0.246–0.933), and history of hypertension (OR, 1.674; 95% CI, 1.114–2.516) were significantly associated with not undergoing eye examinations for diabetic retinopathy in elderly diabetic patients aged older than 65 years.CONCLUSION: In elderly diabetic patients aged older than 65 years living in Korea, those aged older than 80 years, who are current smokers, and with a history of hypertension showed low rates of undergoing eye examinations for diabetic retinopathy, while those with poor subjective health status and a history of stroke had high rates of undergoing eye examinations.

Background: Tobacco smoking is the most preventable cause of diseases and death in older adults. This study aimed to evaluate the factors associated with the intention to quit smoking in elderly Korean men. Methods: We investigated 813 male smokers aged 65 years or more from the 5th and 6th Korea National Health and Nutrition Examination Survey 2010–2015. Multiple logistic regression analysis was performed to identify factors related with smoking cessation intention. Results: Of the respondents, 26.3% had the intention to quit smoking. After adjustment for confounding factors, the intention to quit smoking was significantly associated with a history of ischemic heart disease (adjusted odds ratio, 1.88; 95% confidence interval, 1.02–3.48). Conclusion Identifying the factors related to the intention to quit smoking among older adults can help in developing effective smoking cessation strategies for this section of the population.

Background: Following success of the phase III PROfound trial, the poly (ADP-ribose) polymerase (PARP) inhibitor olaparib was approved by the US Food and Drug Administration in May 2020 for adult patients with deleterious homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). As locally adopted multigene panel next-generation sequencing (NGS) assays for selecting PARP inhibitor candidates have not been thoroughly evaluated, we compared the analytical performance of the FoundationOne CDx (Foundation Medicine, Inc., Cambridge, MA, USA) (central laboratory) and other NGS assays (local laboratory) with samples from the PROfound trial in Korea. Methods: One hundred PROfound samples (60 HRR mutation [HRRm] cases and 40 non-HRRm cases) were analyzed. The results of HRR gene mutation analysis were compared between the FoundationOne CDx and two other NGS assays [SureSelect Custom Design assay (Agilent Technologies, Inc., Santa Clara, CA, USA) and Oncomine Comprehensive assay (Thermo Fisher Scientific, Inc., Waltham, MA, USA)]. Results: The positive percent agreement for single nucleotide variants (SNVs) and insertion/deletions (indels) between the central laboratory and local laboratory was 98.7%–100.0%. The negative percent agreement and overall percent agreement (OPA) for SNVs and indels between central and local laboratories were both 100%. Compared with that of the FoundationOne CDx assay, the OPA for copy number variations of the Oncomine Comprehensive and SureSelect Custom assays reached 99.8%–100%. Most mCRPC patients harboring a deleterious genetic variant were successfully identified with both local laboratory assays. Conclusions The NGS approach at a local laboratory showed comparable analytical performance for identifying HRRm status to the FoundationOne CDx assay used at the central laboratory.

PURPOSE: To evaluate the effect of repeated debulking surgery for high-grade pseudomyxoma peritonei (PMP) originating from the appendix.METHODS: Between January 1998 and December 2014, fifty patients, who underwent debulking surgery for high-grade PMP originating from the appendix, were obtained from a prospectively collected database and retrospectively analyzed. Two groups according to the number of operations were divided and analyzed.RESULTS: A total of 118 operations were performed. Thirty-one patients received more than two operations. The median interval between operations was 18.2 months (range, 2–170 months). Complications developed after 26 operations (22.0%), including ileus (n=10), intra-abdominal fluid collection (n=7), surgical site infection (n=5), and others. There were two mortalities within 30 days after operation. Between two groups of patients who received one operation only and patients who received more than two operations, transfusion, diversion operation, and postoperative complication rate showed statistically significant differences. Two groups of patients had no differences in overall survival rates.CONCLUSION: Our results indicate that the number of operations does not affect the survival rate of high-grade appendiceal PMP, in which repeated debulking surgery is vital to relieve symptoms of the tumor burden.

Background: Nonpharmacological interventions (NPIs) reduce the incidence of respiratory infections. After NPIs imposed during the coronavirus disease 2019 pandemic ceased, respiratory infections gradually increased worldwide. However, few studies have been conducted on severe respiratory infections requiring hospitalization in pediatric patients.This study compares epidemiological changes in severe respiratory infections during pre-NPI, NPI, and post-NPI periods in order to evaluate the effect of that NPI on severe respiratory infections in children. Methods: We retrospectively studied data collected at 13 Korean sentinel sites from January 2018 to October 2022 that were lodged in the national Severe Acute Respiratory Infections (SARIs) surveillance database. Results: A total of 9,631 pediatric patients were admitted with SARIs during the pre-NPI period, 579 during the NPI period, and 1,580 during the post-NPI period. During the NPI period, the number of pediatric patients hospitalized with severe respiratory infections decreased dramatically, thus from 72.1 per 1,000 to 6.6 per 1,000. However, after NPIs ceased, the number increased to 22.8 per 1,000. During the post-NPI period, the positive test rate increased to the level noted before the pandemic. Conclusion Strict NPIs including school and daycare center closures effectively reduced severe respiratory infections requiring hospitalization of children. However, childcare was severely compromised. To prepare for future respiratory infections, there is a need to develop a social consensus on NPIs that are appropriate for children.

This study was to investigate the effects of individual and district-level socioeconomic status (SES) on the development of cognitive impairment among the elderly. A 3-year retrospective observational analysis (2010–2013) was conducted which included 136,217 community-dwelling healthy elderly who participated in the Seoul Dementia Management Project. Cognitive impairment was defined as 1.5 standard deviations below the norms on the Mini-mental status examination. In the individual lower SES group, the cumulative incidence rate (CIR) of cognitive impairment was 8.7% (95% confidence interval [CI], 8.64–8.70), whereas the CIR in the individual higher SES group was 4.1% (95% CI, 4.08–4.10). The CIR for lower district-level SES was 4.7% (95% CI, 4.52–4.86), while that in the higher district-level SES was 4.3% (95% CI, 4.06–4.44). There were no additive or synergistic effects between individual and district-level SES. From this study, the individual SES contributed 1.9 times greater to the development of cognitive impairment than the district-level SES, which suggests that individual SES disparities could be considered as one of the important factors in public health related to cognitive impairment in the elderly.
