Purpose: This study compared clinical outcomes depending on the fixation modality in patients who underwent arthrodesis surgery for Eaton-Littler stage III trapeziometacarpal (TM) joint arthritis between 2009 and 2022. Methods: In total, 39 patients with 44 hands (five patients had surgery on both hands) were selected. Depending on the operative fixation instruments, patients were divided into two groups: group 1, surgery with 25-gauge interosseous wiring and Kirschner wire or headless screw fixation; group 2, surgery with only multiple headless screws for fixation. Bone union was achieved at 62 days after surgery in group 1 and 75 days in group 2 (p=0.165). Results: The preoperative mean visual analogue scores improved during the postoperative outpatient follow-up period in both groups (group 1, from 4.0 preoperatively to 1.0 at the final follow-up; group 2, from 5.0 preoperatively to 2.0 at the final follow-up). Mean grip strength and pinch strength increased after surgery. One patient (4.8%) experienced nonunion in group 1, whereas nonunion occurred in four patients (17.4%) in group 2. This difference was not statistically significant. Four patients in group 1 and no patients in group 2 underwent fixation instrument removal after sound union. Conclusion Adequate stability can be achieved during arthrodesis by combining interosseous wiring and other implants or multiple headless compression screws, resulting in successful outcomes for patients with Eaton-Littler stage III degenerative TM arthritis.

Purpose: In men with metastatic castration-resistant prostate cancer (mCRPC), new bone lesions are sometimes not properly categorized through a confirmatory bone scan, and clinical significance of the test itself remains unclear. This study aimed to demonstrate the performance rate of confirmatory bone scans in a real-world setting and their prognostic impact in enzalutamide-treated mCRPC. Materials and Methods: Patients who received oral enzalutamide for mCRPC during 2014-2017 at 14 tertiary centers in Korea were included. Patients lacking imaging assessment data or insufficient drug exposure were excluded. The primary outcome was overall survival (OS). Secondary outcomes included performance rate of confirmatory bone scans in a real-world setting. Kaplan-Meier analysis and multivariate Cox regression analysis were performed. Results: Overall, 520 patients with mCRPC were enrolled (240 [26.2%] chemotherapy-naïve and 280 [53.2%] after chemotherapy). Among 352 responders, 92 patients (26.1%) showed new bone lesions in their early bone scan. Confirmatory bone scan was performed in 41 patients (44.6%), and it was associated with prolonged OS in the entire population (median, 30.9 vs. 19.7 months; p < 0.001), as well as in the chemotherapy-naïve (median, 47.2 vs. 20.5 months; p=0.011) and post-chemotherapy sub-groups (median, 25.5 vs. 18.0 months; p=0.006). Multivariate Cox regression showed that confirmatory bone scan performance was an independent prognostic factor for OS (hazard ratio 0.35, 95% confidence interval, 0.18 to 0.69; p=0.002). Conclusion Confirmatory bone scan performance was associated with prolonged OS. Thus, the premature discontinuation of enzalutamide without confirmatory bone scans should be discouraged.

Objective: The incidence of hip fractures is increasing worldwide with the aging population, causing a challenge to healthcare systems due to the associated morbidities and high risk of mortality. After hip fractures in frail geriatric patients, existing comorbidities worsen and new complications are prone to occur. Comprehensive rehabilitation is essential for promoting physical function recovery and minimizing complications, which can be achieved through a multidisciplinary approach. Recommendations are required to assist healthcare providers in making decisions on rehabilitation post-surgery. Clinical practice guidelines regarding rehabilitation (physical and occupational therapies) and management of comorbidities/complications in the postoperative phase of hip fractures have not been developed. This guideline aimed to provide evidence-based recommendations for various treatment items required for proper recovery after hip fracture surgeries. Methods Reflecting the complex perspectives associated with rehabilitation post-hip surgeries, 15 key questions (KQs) reflecting the complex perspectives associated with post-hip surgery rehabilitation were categorized into four areas: multidisciplinary, rehabilitation, community-care, and comorbidities/complications. Relevant literature from four databases (PubMed, EMBASE, Cochrane Library, and KoreaMed) was searched for articles published up to February 2020. The evidence level and recommended grade were determined according to the grade of recommendation assessment, development, and evaluation method. Results A multidisciplinary approach, progressive resistance exercises, and balance training are strongly recommended. Early ambulation, weigh-bearing exercises, activities of daily living training, community-level rehabilitation, management of comorbidities/complication prevention, and nutritional support were also suggested. This multidisciplinary approach reduced the total healthcare cost. Conclusion This guideline presents comprehensive recommendations for the rehabilitation of adult patients after hip fracture surgery.

Background and Objectives: Smoking is well-established as a risk factor for coronary artery disease. However, recent studies demonstrated favorable results, including reduced mortality, among smokers, which are referred to as the “smoker's paradox”. This study examined the impact of smoking on clinical outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). Methods: Patients with AMI undergoing PCI between 2004 and 2014 were enrolled and classified according to smoking status. The primary endpoint was a composite of major adverse cardiovascular events (MACE) including cardiac death, myocardial infarction, stroke, and revascularization. Results: Among the 10,683 patients, 4,352 (40.7%) were current smokers. Smokers were 10.7 years younger and less likely to have comorbidities such as hypertension, diabetes mellitus, chronic kidney disease, stroke, and prior PCI. Smokers had less MACE (hazard ratio [HR], 0.644; 95% confidence interval [CI], 0.594–0.698; p<0.001) and cardiac death (HR, 0.494; 95% CI, 0.443–0.551; p<0.001) compared to nonsmokers during the 5 years in an unadjusted model. However, after propensity-score matching, smokers showed higher risk of MACE (HR, 1.125; 95% CI, 1.009–1.254; p=0.034) and cardiac death (HR, 1.190; 95% CI, 1.026–1.381; p=0.022). Smoking was a strong independent predictor of lung cancer (propensityscore matched HR, 2.749; 95% CI, 1.416–5.338; p=0.003). Conclusions In contrast to the unadjusted model, smoking is associated with worse cardiovascular outcome and higher incidence of lung cancer after adjustment of various confounding factors. This result can be explained by the characteristics of smokers, which were young and had fewer comorbidities.

Pituicytoma is a rare solid benign tumor of the sellar and/or suprasellar region originating from the pituicytes of the neurohypophysis or infundibulum, which is not differentiated from a pituitary adenoma that is diagnosed mostly in the sellar and/or suprasellar region. In addition, cystic tumors are very rare and have not been reported due to their solid and hypervascular natures. A 33-year-old man presented with a chronic headache which exacerbated recently. MRI was performed and revealed a cystic tumor in the sellar and suprasellar regions with a small parenchymal island in the cyst compressing the optic chiasm. The endoscopic endonasal transsphenoidal approach was used to remove the tumor. Immunohistochemical staining was positive for thyroid transcription factor 1, S-100 protein, and glial fibrillary acidic protein. The pituicytoma was diagnosed based on histologic findings. The authors review herein the literature on clinical presentation, diagnosis, surgical management, and outcome.

Community-based preconception care for men and women of childbearing age has been introduced in Seoul. The program aims to focus on problem areas such as low birth rate, fertility issues potentially due to late marriages, preterm or premature births, and low-birthweight in newborn babies. The district administration officials of Seoul, as well as, academics from the Korean Society of Maternal and Child Health, developed a protocol by using a questionnaire and laboratory test for screening risk factors in pregnancy. The protocol was tested on a trial basis in four local districts in Seoul from July 2017 to 2018, extended to 12 local districts in 2019, and all 25 districts in Seoul in 2020. The protocol includes AntiMullerian Hormone tests to assess women’s ovarian reserve and male health checkups that include semen analysis and physical examinations of genitalia. These tests are conducted for early detection and treatment of infertility, especially in cases of late marriages. In order to prevent women being abandoned during pregnancy (leading them to single-parenting), the protocol also emphasizes building a gender-sen sitive environment by encouraging more male participation. A monitoring group comprised of Seoul city district officials and academics from the Korean Society of Maternal and Child Health, regularly visited the local districts to observe improvements and keep the program officials up to date. In addition, the group also conducted a mobile phone survey for feedback on the program. The interest and support of the resi dents in Seoul city, and positive results and development in pregnancy care and childbirth, are needed to stabilize and extend this protocol.

OBJECTIVE: This study investigated the associations of suicidal ideation (SI) evaluated within 2 weeks after an acute coronary syndrome (ACS) episode with functioning, disability, and quality of life (QOL) at a 1-year follow-up assessment. METHODS: This study recruited 1152 consecutive patients within 2 weeks of a confirmed ACS episode; 828 of these patients who were followed up 1 year later comprised the study sample. SI was determined at baseline using the “suicidal thoughts” item of the MontgomeryÅsberg Depression Rating Scale. At both examinations, social and occupational functioning were measured by the Social and Occupational Functioning Assessment Scale (SOFAS), disability was estimated by World Health Organization Disability Assessment Schedule-12 (WHODAS-12), and QOL was assessed using the World Health Organization Quality of Life-Abbreviated form (WHOQOL-BREF). Baseline covariates included sociodemographic data, depression characteristics, cardiovascular risk factors, and current cardiac status. RESULTS: SI at baseline was independently associated with less improved or decreased scores on the SOFAS, WHODAS-12, and WHOQOL-BREF over 1 year after adjusting for relevant covariates. CONCLUSION: SI within 2 weeks of an ACS episode predicted poorer functioning and QOL at a 1-year follow-up assessment. Thus, the simple evaluation of SI in patients with recently developed ACS could be helpful in screening for functioning and QOL during the chronic phase of this disease.

Despite the great socioeconomic burden of stroke, there have been few reports of stroke statistics in Korea. In this scenario, the Epidemiologic Research Council of the Korean Stroke Society launched the “Stroke Statistics in Korea” project, aimed at writing a contemporary, comprehensive, and representative report on stroke epidemiology in Korea. This report contains general statistics of stroke, prevalence of behavioral and vascular risk factors, stroke characteristics, pre-hospital system of care, hospital management, quality of stroke care, and outcomes. In this report, we analyzed the most up-to-date and nationally representative databases, rather than performing a systematic review of existing evidence. In summary, one in 40 adults are patients with stroke and 232 subjects per 100,000 experience a stroke event every year. Among the 100 patients with stroke in 2014, 76 had ischemic stroke, 15 had intracerebral hemorrhage, and nine had subarachnoid hemorrhage. Stroke mortality is gradually declining, but it remains as high as 30 deaths per 100,000 individuals, with regional disparities. As for stroke risk factors, the prevalence of smoking is decreasing in men but not in women, and the prevalence of alcohol drinking is increasing in women but not in men. Population-attributable risk factors vary with age. Smoking plays a role in young-aged individuals, hypertension and diabetes in middle-aged individuals, and atrial fibrillation in the elderly. About four out of 10 hospitalized patients with stroke are visiting an emergency room within 3 hours of symptom onset, and only half use an ambulance. Regarding acute management, the proportion of patients with ischemic stroke receiving intravenous thrombolysis and endovascular treatment was 10.7% and 3.6%, respectively. Decompressive surgery was performed in 1.4% of patients with ischemic stroke and in 28.1% of those with intracerebral hemorrhage. The cumulative incidence of bleeding and fracture at 1 year after stroke was 8.9% and 4.7%, respectively. The direct costs of stroke were about ₩1.68 trillion (KRW), of which ₩1.11 trillion were for ischemic stroke and ₩540 billion for hemorrhagic stroke. The great burden of stroke in Korea can be reduced through more concentrated efforts to control major attributable risk factors for age and sex, reorganize emergency medical service systems to give patients with stroke more opportunities for reperfusion therapy, disseminate stroke unit care, and reduce regional disparities. We hope that this report can contribute to achieving these tasks.
