The Effect of Elastic Eyelid Band Application on Bilateral Severe Ptosis in a Patient With Bilateral Incomplete Claude's Syndrome: A Case Report.

Patients with brainstem stroke can present with various oculomotor disorders, including ptosis. Neurogenic ptosis, which results from total or partial dysfunction of the third cranial nerve and/or the Müller muscle, can significantly restrict activities of daily living and participation in rehabilitation. Therefore, surgical intervention is an effective therapeutic strategy. However, owing to complications associated with incomplete eyelid closure, such as exposure keratitis and corneal injury, patients with neurogenic ptosis should first be observed, as natural recovery without surgery can be expected despite a poor prognosis. We reported the case of a 66-year-old woman with bilateral Claude syndrome who presented with severe bilateral ptosis, quadriparesis, and cognitive impairment after a bilateral midbrain infarction. After 3 months of intensive rehabilitation using soft elastic eyelid bands, her ptosis improved without the need for eyelid bands and visual field significantly increased, with improved functional level to the point of walking independently without assistance. This report demonstrates the potential advantages of the simple yet effective nonsurgical intervention of a soft elastic eyelid band for ptosis to restore significant functional gains in patients with severe bilateral ptosis after acute stroke.

Association between Low Blood Pressure and Subsequent Risk of Parkinson's Disease in Older Adults Aged ≥75 Years.

INTRODUCTION: The association between blood pressure (BP) and incidence of Parkinson's disease (PD) in older adults remains uncertain. Therefore, this study aimed to investigate the association between BP (high or low) and PD incidence in adults aged ≥75 years. METHODS: In this nationwide population-based cohort study, we enrolled participants aged ≥75 years without a prior PD diagnosis who had undergone health examination provided by the Korean National Health Insurance Service at least once from January 1, 2009, to December 31, 2012. The participants were followed up until December 31, 2019, or the date of their death. The Cox proportional hazards model was used to assess the risk of PD depending on systolic BP (SBP), diastolic BP (DBP), and pulse pressure. RESULTS: Overall, 963,525 participants were enrolled in the analysis and followed up until December 31, 2019, or the date of death (40.7% male, mean age 78.5 ± 3.6 years). The mean SBP and DBP were 131.4 ± 16.7 and 77.9 ± 10.3 mm Hg, respectively. During the 10-year follow-up period, 16,414 (1.7%) newly diagnosed cases of PD were reported. A significant inverse dose-response association was found between SBP and PD incidence. In the subgroup analysis, this association was maintained for most variables, including sex, use of antihypertensive medication, comorbidities, alcohol consumption, physical activity, and body mass index, except for smoking status. CONCLUSION: Lower SBP and DBP were associated with a higher PD incidence in older adults. These results may have substantial implications for determining the optimal BP control target in adults aged ≥75 years.

Association between smoking and all-cause mortality in Parkinson's disease.

We aimed to investigate the association between smoking status and all-cause mortality of Parkinson's disease (PD). Among the whole nationwide population data from Korea National Health Insurance Service, newly diagnosed PD was selected, and all-cause mortality was evaluated. The systematic review was performed through a literature search on the PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases. Among 26,080 individuals with PD, there was no significant association between smoking status and all-cause mortality in a nationwide cohort study (ex-smoker, HR 0.1.03, 95% CI 0.97-1.10; current smoker, HR 1.06, 95% CI 0.96-1.16). The systematic review, including six prospective cohort studies, also found a nonsignificant association. PD smokers tended to have fewer deaths from neurologic causes but were significantly more likely to die from smoking-related cancers such as lung cancer. We presented a nonsignificant association between smoking and mortality of PD, and cigarette smoking is not recommended in individuals with PD.

Machine learning based risk prediction for Parkinson's disease with nationwide health screening data.

Although many studies have been conducted on machine learning (ML) models for Parkinson's disease (PD) prediction using neuroimaging and movement analyses, studies with large population-based datasets are limited. We aimed to propose PD prediction models using ML algorithms based on the National Health Insurance Service-Health Screening datasets. We selected individuals who participated in national health-screening programs > 5 times between 2002 and 2015. PD was defined based on the ICD-code (G20), and a matched cohort of individuals without PD was selected using a 1:1 random sampling method. Various ML algorithms were applied for PD prediction, and the performance of the prediction models was compared. Neural networks, gradient boosting machines, and random forest algorithms exhibited the best average prediction accuracy (average area under the receiver operating characteristic curve (AUC): 0.779, 0.766, and 0.731, respectively) among the algorithms validated in this study. The overall model performance metrics were higher in men than in women (AUC: 0.742 and 0.729, respectively). The most important factor for predicting PD occurrence was body mass index, followed by total cholesterol, glucose, hemoglobin, and blood pressure levels. Smoking and alcohol consumption (in men) and socioeconomic status, physical activity, and diabetes mellitus (in women) were highly correlated with the occurrence of PD. The proposed health-screening dataset-based PD prediction model using ML algorithms is readily applicable, produces validated results, and could be a useful option for PD prediction models.

Menstrual and Reproductive Factors for Gastric Cancer in Postmenopausal Women: The 2007-2020 Korea National Health and Nutrition Examination Survey.

Globally, the incidence of gastric cancer is lower in women than in men. It is thought that menstrual and reproductive factors may be related to their lower incidence of gastric cancer. This cross-sectional study examined menstrual, reproductive, and other factors in 20,784 postmenopausal women from the 2007-2020 Korea National Health and Nutrition Examination Survey (KNHANES). A univariate logistic regression analysis was performed, and then a multivariate logistic regression analysis for significant factors in the univariate analysis was conducted. In the multivariate logistic regression analysis, the age at menarche (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.00-1.06, p = 0.035) and myocardial infarction (OR 2.43, 95% CI 1.05-5.62, p = 0.026) showed a significant association with increased incidence of gastric cancer. The age at menopause (OR 0.97, 95% CI 0.95-1.00, p = 0.03), the age at the first childbirth (OR 0.93, CI 0.89-0.97, p = 0.007), and the experience of alcohol consumption (OR 0.68, 95% CI 0.5-0.91, p = 0.003) showed a significant association with a decreased incidence of gastric cancer. Late menarche, early menopause, early aged first childbirth, and myocardial infarction are estimated to be risk factors for gastric cancer in postmenopausal Korean women.

Recurrent atypical leiomyoma in bladder trigone, confused with uterine fibroids: A case report.

BACKGROUND: Tumors originating from the posterior bladder wall can be challenging to diagnose because they may mimic a mass from the uterine cervix. Atypical leiomyoma of the bladder trigone is extremely rare, with few reported cases, and requires caution during surgery to avoid damage to the adjacent ureter. Diagnostic surgery and confirmational pathology are essential to assess whether the tumor is malignant and relieve clinical symptoms. Herein, we describe a case of recurrent leiomyoma with focal atypia in the bladder trigone. CASE SUMMARY: A 29-year-old woman with a uterine fibroid incidentally found at a regular checkup was referred to our hospital. Based on magnetic resonance imaging, either urinary bladder leiomyoma or protrusion of pedunculated uterine cervical fibroid into the bladder was suspected. This leiomyoma in the trigone of the bladder was completely excised by laparotomy, and the patient was discharged without complication. Follow-up outpatient ultrasonography identified tumor recurrence after four years. As focal atypia was identified previously, laparotomy was performed to confirm the pathology. A round solid mass was resected from the posterior bladder wall without injuring either ureteric orifice. This tumor was pathologically diagnosed as a leiomyoma without atypia. Three-year follow-up ultrasonography has revealed no recurrence. CONCLUSION: Atypical leiomyoma in bladder trigone is rare and could be easily mistaken for fibroid in the uterine cervix. To confirm histopathology, surgical excision is mandatory and regular follow-up is necessary to detect recurrence.

Lifestyle Factors and Parkinson Disease Risk: Korean Nationwide Cohort Study With Repeated Health Screening Data.

BACKGROUND AND OBJECTIVES: Many previous studies, mostly performed in Western countries, on the effects of lifestyle factors on Parkinson disease (PD) used baseline lifestyle characteristics without directly accounting for changes in covariate values over time. The objective of this study was to evaluate the association of repeatedly measured lifestyle factors with PD risk in a Korean population. METHODS: We conducted a nationwide population-based cohort study. Among 512,836 Koreans in the national health checkup database, we selected individuals who underwent health screening ≥3 times between 2002 and 2015 and followed up until December 31, 2015. PD was defined using the ICD-10 code G20 (with ≥3 times clinic visits for PD, to increase the diagnostic validity). Data on lifestyle factors such as smoking, alcohol consumption, and physical activity were collected using self-reported questionnaires. Logistic regression analysis with time-dependent covariates using generalized estimation equation models was performed to determine PD development. RESULTS: During the 14-year follow-up, 2,665 patients developed PD. Smoking showed a dose-response inverse association with PD only in men (ex-smoker, odds ratio [OR] 0.782, 95% confidence interval [CI] 0.713-0.858; current smoker, OR 0.556, 95% CI 0.488-0.632). Alcohol consumption and regular physical activity were related to reduced PD development in both sexes; however, alcohol consumption in men (≤3 per week, OR 0.717, 95% CI 0.658-0.780; ≥4 per week, OR 0.745, 95% CI 0.644-0.861) and physical activity in women (moderate, OR 0.792, 95% CI 0.748-0.840; vigorous, OR 0.830, 95% CI 0.756-0.911) had more consistent associations with PD development compared to those of the other sex. Participants with regular health screening showed a consistent relationship between lifestyle factors and PD development, whereas lifestyle factors in those without regular health screening had a decreased relationship with PD, even smoking habit. CONCLUSIONS: Analysis using repeatedly measured lifestyle factors showed an association between lifestyle factors and PD development. Characteristics of lifestyle data including repeated measurements, timing, or regularity might influence results, and future studies with appropriate lifestyle factors could increase PD risk prediction. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that smoking, alcohol use, and physical activity are associated with reduced risk of PD in a Korean population.

Clinicopathological Characteristics of Squamous Cell Carcinoma and High-grade Squamous Intraepithelial Lesions Involving Endocervical Polyps.

BACKGROUND/AIM: To investigate the clinicopathological characteristics of high-grade squamous intraepithelial lesions (HSILs) and squamous cell carcinomas (SCCs) involving endocervical polyps (ECPs). PATIENTS AND METHODS: We collected the endocervical polypectomy cases and performed pathological examination and cytohistological correlation. RESULTS: During a period of 12 years, 21 (1.1%) HSILs and two (0.1%) SCCs involving ECPs were identified in 1,905 cases. Twelve (63.1%) of the 19 cases were cytohistologically concordant. In five HSILs and one SCC with polypectomy margin involvement, residual HSIL was identified in conization or hysterectomy specimens. Furthermore, in two HSIL patients and one SCC patient with negative polypectomy margins, residual HSILs were found in the conization specimens. CONCLUSION: The prevalence of HSIL and SCC involving ECP in our cohort was similar to the rates found in previous studies. The presence of residual HSIL in nonpolypoid cervical tissue regardless of the polypectomy margin involvement suggests that conization or hysterectomy is needed for diagnostic or treatment purposes.

Clinical Practice Guideline for Cardiac Rehabilitation in Korea.

BACKGROUND: Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and 3 additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. METHODS: This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of 33 authors-primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and 2 general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, 3 rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. RESULTS: CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers cardiovascular mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. CONCLUSION: Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

Cohort study of cervical ossification of posterior longitudinal ligament in a Korean populations: Demographics of prevalence, surgical treatment, and disability.

OBJECTIVE: To investigate the demographic characteristics of cervical ossification of posterior longitudinal ligament (OPLL) including prevalence, surgical treatment, and disability in Korean population using Korean National Health Insurance Service National Sample Cohort (NHIS-NSC) data, and to analyze association between accessibility for surgical treatment and socioeconomic factors. PATIENTS AND METHODS: A population-based cohort study was conducted using stratified representative sampling from NHIS-NSC data from the year 2002 to 2013. We analyzed prevalence and distribution of cervical OPLL according to age, sex, and socioeconomic factors. Multiple logistic regression analysis was conducted to investigate associations between independent variables and the rate of surgical treatment. RESULTS: The overall prevalence of cervical OPLL was 190 per 100,000 people in Korea, and 11.4% of male patients and 4.0% of female patients received surgical treatment. Logistic regression analysis revealed that male patients received more surgical treatment than did female patients, also income level and residential area influence the rate of surgical treatment in females after adjustment of covariates (p< 0.05). Disability rate associated with cervical OPLL was 2.27% in male and 0.99% in female patients. CONCLUSION: In this cohort study, the prevalence of cervical OPLL was 190 per 100,000 people. Male patients received more surgery, and disability rate of male was higher than female patients. Although surgical treatment is covered by medical insurance in Korea, socioeconomic factors such as income level and residential area influence the treatment plans in females. These findings can help in the understanding of disease progression and can inform surgical treatment plans to reduce disability.

Pulmonary Rehabilitation in a Patient With Bronchiectasis and Underlying Cerebral Palsy: A Case Presentation.

Bronchiectasis is a chronic pulmonary disease characterized by the permanent dilatation of the airways, with recurrent infections. As the disease progresses, extrapulmonary symptoms manifest. If the patient with bronchiectasis has an underlying central nervous system disease such as cerebral palsy (CP), extrapulmonary functions decline faster. The co-occurrence of these 2 diseases may make care more complex, and there have been no reports about pulmonary rehabilitation (PR) in this class of patients. Here, we present a patient with bronchiectasis and underlying CP who showed marked improvement of pulmonary function and clinical symptoms after 6 weeks of a patient-specific intensive PR program. LEVEL OF EVIDENCE: IV.

Single-port laparoscopic salpingectomy for surgical treatment of tubal pregnancy: comparison with multi-port laparoscopic salpingectomy.

BACKGROUND: This study investigates the safety and feasibility of transumbilical single-port laparoscopic salpingectomy (SPLS) using conventional laparoscopic instruments compared to conventional multi-port laparoscopic salpingectomy (MPLS) for surgical treatment of tubal pregnancy. MATERIAL AND METHODS: We conducted a retrospective analysis of 63 patients with tubal pregnancy who underwent SPLS and 71 patients who underwent conventional MPLS between January 2008 and December 2010. All patients in the SPLS group had a drainage tube placed through the umbilicus, and, in the MPLS group, through a 5-mm trocar site in one side of the lower abdomen. RESULTS: No significance difference was discovered between the groups with regard to adjusted hemoglobin values (SPLS, 1.9 ± 1.0 g/dL versus MPLS, 1.7 ± 1.0 g/dL, P = 0.335). Additionally, there was also no significant difference in clinical characteristics, intraoperative findings, or operative outcomes. CONCLUSIONS: Our study demonstrated that transumbilical SPLS using conventional laparoscopic instruments has operative outcomes comparable to MPLS for the surgical treatment of tubal pregnancy. Transumbilical SPLS may therefore be offered as a feasible alternative to MPLS.

Target-based molecular signature characteristics of cervical adenocarcinoma and squamous cell carcinoma.

There is an urgent need for molecular marker studies of adenocarcinoma (AC) and squamous cell carcinoma (SCC) of the uterine cervix. This study utilized oligomicroarray and pathway analyses to characterize a transcriptomic signature with molecular networks associated with AC and SCC. A 10K oligomicroarray was used to identify potential transcripts that were differentially expressed in cervical cancers from 28 patients and common reference RNAs from 17 different normal cervixes. Molecular networks were correlated using genomics tools to globally explore cellular pathways. Gene expression levels of 46 transcripts separated cancer samples into AC and SCC groups. Genes including: KRT17, IGFBP2, CALCA and VIPR1 were differentially expressed in AC and SCC. In addition, we identified a transcriptomic signature that predicted tumor classification and progression based upon its cellular processes. The downregulated signatures for SCC were cell death of pheochromocytoma cells (P=0.0037), apoptosis of neurons (P=0.009) and damage to DNA (P=0.0038). By contrast, the upregulated molecular signatures in AC were immunological disorder (P=0.006), splenomegaly (P=0.0053) and hepatic system disorder (P=0.006). The G2/M DNA damage checkpoint regulation pathway (P=0.05) was found to be significantly linked to IGF1R as a new regulatory component of a putative cytoplasmic signaling cascade in SCC. By contrast, the antigen presenting canonical pathway (P=0.038) appeared to be linked to PPARγ in AC. Taken together, these experiments provide important new information regarding the role of molecular networks in mediating SCC and AC, possibly through two independent pathways, and contribute to provide new targets for the prevention and treatment of cervical cancer.

Comparison of single-, double- and triple-combined testing, including Pap test, HPV DNA test and cervicography, as screening methods for the detection of uterine cervical cancer.

Cervical cancer is a serious disease that threatens the health of women worldwide. This study compared the sensitivities and false-positive rates of cervical cytology (Pap smear), human papilloma virus (HPV) DNA test, cervicography, first double-combined testing (cervical cytology and HPV DNA test), second double-combined testing (cervical cytology and cervicography) and triple-combined testing (cervical cytology, HPV DNA test and cervicography). The study included 261 patients screened for uterine cervical cancer. All women simultaneously underwent cervical cytology, HPV DNA test and cervicography for uterine cervical cancer screening and colposcopically directed biopsy for diagnostic evaluation. The triple-combined testing was consistently the most sensitive among the cervical screening tests. The second double-combined testing, with a sensitivity rate of 98.1% was more sensitive than the first double-combined test (92.3%). However, cervical cytology was most specific (93.5%) and showed the highest positive predictive value (77.8%). The sensitivity of cervical cytology was markedly improved in combination with HPV DNA test and cervicography. Thus, the triple-combined testing, which improves the high false negativity of cervical cytology, may be an effective tool in uterine cervical cancer screening, pending confirmation of the effectiveness in a mass screening study.

Identification of candidate biomarkers using the Experion™ automated electrophoresis system in serum samples from ovarian cancer patients.

Ovarian cancer is the most common cause of disease-related death in women globally. Detection of ovarian cancer using new biomarkers is necessary for early diagnosis. To date, there have been no obvious biomarkers for ovarian cancer detection in the incipient stage. In this study, we discovered potential diagnostic serological biomarkers for ovarian cancer using the Experion™ automated electrophoresis system. Sera from 14 healthy women and 84 ovarian cancer patients at stages I- IV were applied to the Experion to compare the protein expression levels. To examine the protein expression pattern of Experion data, proteins in the samples were resolved using 10 and 15% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and visualized by silver staining. The candidate biomarkers elevated in ovarian cancer were purified and determined using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. α-2-macroglobulin (173.7 kDa), ceruloplasmin (147 kDa), inter-α-trypsin inhibitor family heavy chain-related protein (126 kDa), C-1 inhibitor (115.2 kDa) and hemoglobin α/ß (14.4 kDa were overexpressed in the ovarian cancer sera. This study documents a novel way to measure ovarian cancer or cancer-related proteins for biomarkers using the Experion assay system, which should be easily adaptable for high-throughput diagnosis to establish databases of ovarian cancer for clinical applications.

Pure nongestational choriocarcinoma of the ovary: a case report.

Pure ovarian choriocarcinoma can be gestational or nongestational in origin. Nongestational choriocarcinoma of the ovary is extremely rare, and its diagnosis is very difficult during the reproductive years. We present a case of a 33-year-old woman diagnosed with pure nongestational ovarian choriocarcinoma. Following surgery, multiple courses of a chemotherapy regimen of etoposide, methotrexate, and actinomycin-D (EMA) were effective.

Simultaneous bilateral quadriceps tendon rupture in a patient with chronic renal failure.

Bilateral quadriceps tendon rupture is an unusual injury, but may be encountered in patients with various chronic diseases after minor trauma. This article presents a case of bilateral quadriceps tendon rupture of a 38-year-old woman with chronic renal failure. Surgical repair was performed using a bone tunnel technique with a nonabsorbable suture and a suture anchor. Postoperative magnetic resonance imaging confirmed complete healing of the repair site, and clinically active extension with 120 degrees of range of motion was achieved.

Disseminated peritoneal leiomyomatosis after hysterectomy: a case report.

BACKGROUND: Disseminated peritoneal leiomyomatosis (DPL) is a rare disease characterized by multiple benign leiomyomas arising in the pelvic and abdominal cavities in women. DPL is observed particularly in reproductive age groups and often mimics carcinomatosis grossly, but with benign histology and a favorable prognosis. The possible causes could be divided into hormonal, subperitoneal mesenchymal stem cells, metaplasia, genetic or iatrogenic after morcellation of myoma during laparoscopic surgery. Management includes surgery followed by adjuvant hormonal therapy, systemic chemotherapy or aromatase inhibitor treatment in cases of nonresectable disease. CASE: We report a case of DPL occurring after 2 previous operations including myomectomy and hysterectomy. After the DPL operation, the patient was treated with a gonadotropin-releasing hormone agonist for 6 months. One year after surgery, image analysis showed no evidence of disease. CONCLUSION: This rare condition must be considered even when a patient presents with abdominal masses after myomectomy followed by hysterectomy.
