ABSTRACT

Background@#Though antenatal magnesium sulfate (MgSO4 ) is widely used for fetal neuroprotection, suspicions about the long-term neuroprotection of antenatal MgSO4 have been raised. @*Methods@#We investigated short- and long-term outcomes of antenatal MgSO4 use for 468 infants weighing < 1,500 g with a gestational age of 24–31 weeks. @*Results@#Short-term morbidities and the risk of developmental delay, hearing loss, and cerebral palsy at a corrected age of 18–24 months and 3 years of age did not decrease in the MgSO4 group (infants who were exposed to MgSO4 for any purpose) or neuroprotection group (infants who were exposed to MgSO4 for fetal neuroprotection) compared with the control group (infants who were not exposed to MgSO4 ). The z-scores of weight, height, and head circumference did not increase in the MgSO4 group or neuroprotection group compared with the control group. @*Conclusion@#Antenatal MgSO4 including MgSO4 for neuroprotection did not have beneficial effects on long-term neurodevelopmental and growth outcomes.

ABSTRACT

Background@#Prurigo nodularis (PN) is a chronic pruritic skin disorder with a large number of hyperkeratotic nodules. The precise mechanisms of its pathogenesis remain unknown. PN has been linked to atopic dermatitis (AD), but its association remains unclear. @*Objective@#We aimed to investigate the clinical, histological, and immunohistochemical characteristics of patients with PN and PN underlying AD (PN-AD). @*Methods@#Eight patients were recruited for PN, PN-AD, and eight normal subjects, respectively. Skin tissues were obtained from patients and healthy subjects for histological and immunohistochemical analyses. @*Results@#Histological examination showed increased epidermal thickness and dermal inflammatory cell counts in the PN-AD and PN groups compared to normal subjects. Immunohistochemical analyses revealed that the expression of interleukin (IL)-4, IL-13, IL-18, IL-31, IL-33, interferon (IFN)-γ, stromal-derived factor (SDF) 1-α and thymic stromal lymphopoietin (TSLP) was increased in the tissues of PN-AD and PN groups, in which the staining intensities of IL-4, IL-13, SDF1-α and TSLP in the PN-AD group were higher than those in the PN group, but the differences were not statistically significant. Conversely, the staining intensities of IL-18, IL-33 and IFN-γ were significantly higher in the PN group than those in the PN-AD group. @*Conclusion@#The pathogenesis of PN may differ from that of PN-AD, in which IL-18, IL-33 and IFN-γ may be associated, implying that epidermal injury is the initial cause of IL-18 and IL-33 induction, which then increases IFN-γ, resulting in the inflammatory process of PN.

ABSTRACT

Background@#T-score discordance between the spine and hip is commonly observed when dual energy X-ray absorptiometry (DXA) is used to diagnose osteoporosis. However, information is scarce regarding the prevalence and risk factors for this problem in Korea. This study evaluated the prevalence of major/minor discordance and associated risk factors in elderly Korean patients with osteoporotic vertebral compression fractures (OVCFs). @*Methods@#This study included 200 patients (37 men, 163 women) treated for thoracic or lumbar compression fractures between January 2015 and August 2021. DXA was performed to examine T‐scores and determine the prevalence of discordance, defined as a difference between the T-score categories of the femur and spine in the same individual. The t-tests, χ2 tests, and regression analyses were used to assess the associated risk factors of T-score discordance among the subjects. @*Results@#T-score concordance, minor discordance, and major discordance were observed in 137 (68.5%), 59 (29.5%), and 4 (2%) patients with OVCFs, respectively. The spinal T-score was lower than the femoral T-score in all major discordance and 81.3% (48/59) of minor discordant cases. Overall, the only factor related to T-score discordance was the age at fracture (odds ratio, -0.01; P=0.014). @*Conclusions@#The results of this study showed that a significant number of subjects (31.5%) showed spine-hip discordance, even with a mean age in their 80s. More attention should be paid to the appropriate evaluation and management of elderly patients with OVCFs. Moreover, a longitudinal study is necessary to verify the clinical importance of T-score discordance in this population.

ABSTRACT

Objectives@#This study introduced a novel Automatic Needle Destroyer (AND) to an emergency department (ED) and assessed its effect on healthcare providers’ work. @*Methods@#Between August and September 2019, in the ED of a tertiary hospital in Seoul, we conducted a mixed-methods study to evaluate the efficiency, safety, and usability of the AND using video analysis, surveys, and in-depth interviews, wherein participants described the advantages and disadvantages of the AND. @*Results@#Compared to the existing method, introducing the AND significantly reduced the operating time from 2.32 ± 1.14 seconds to 1.77 ± 3.71 seconds (p < 0.001). The normal operation rate was 90.6%. The rate of needle-stick injuries (NSIs) and the mean system usability scale (SUS) showed no significant differences. The in-depth interviews indicated that the disadvantages of the AND were mostly operational. The advantages were related to profit, reduced direct contact with hazardous waste, and behavioral changes, such as not having to recap syringes. @*Conclusions@#We introduced the AND to an ED environment, where NSIs occur frequently and many syringes are used, to evaluate its effect on providers’ work. The AND reduced the time for needle disposal, but the normal operation rate was low. No significant differences were found in the SUS score or the rate of NSIs. Although there are some restrictions on introducing the AND immediately, this study’s results showed its potential usefulness. Efforts to improve the operation of the device and a longer study period are needed to fully achieve safety and efficiency.

ABSTRACT

Purpose@#Cholecystectomy is the gold standard treatment for gallbladder disease. As life expectancy increases, awareness of cholecystitis treatment in the elderly changes. The safety and feasibility of cholecystectomy in octogenarians have been proven in many studies. Surgical treatment for cholecystitis should be considered in octogenarians and even nonagenarians. In this study, we aimed to assess the outcomes of cholecystectomy in octogenarians and nonagenarians with acute cholecystitis. @*Methods@#A total of 393 patients aged 80 to 89 years (352 octogenarians) and 90 to 99 years (41 nonagenarians) diagnosed with acute cholecystitis underwent cholecystectomy between March 2012 and June 2020. All patients were classified according to the Tokyo guidelines. The evaluated parameters included demographic data, surgical outcomes, American Society of Anesthesiologists physical status classification, and Tokyo guidelines. @*Results@#All 393 patients were analyzed and divided into two groups according to age; octogenarians (83.57 ± 2.64 years) and nonagenarians (92.98 ± 3.15 years). The survival rate was 97.7% for octogenarians and 97.6% for nonagenarians. Laparoscopic surgery was performed more in both groups (96.8% in octogenarians and 92.7% in nonagenarians) than open surgery (3.2% in octogenarians and 7.3% in nonagenarians). The operation time of the nonagenarian group (74.63 ± 30.83 minutes) was shorter than the octogenarian group (75.85 ± 34.63 minutes). The incidences of postoperative complications in the octogenarian and nonagenarian groups were as follows: pneumonia, 5.7% and 7.3%; bleeding, 1.7% and 2.4%; gastrointestinal symptoms, 6.0% and 2.4%; and bile leakage, 0.6% and 2.4%, respectively. @*Conclusion@#Cholecystectomy is a safe and efficient procedure for the treatment of acute cholecystitis in both octogenarians and nonagenarians.

ABSTRACT

A 5-year-old dog was evaluated for a lethargy and respiratory distress. Radiograph revealed cardiomegaly with pleural effusion, and the dog died during a thoracocentesis. At necropsy, the descending aorta and pulmonary trunk were dilated and in close contact, but there was no external evidence of a patent ductus arteriosus (PDA). When the descending aorta was opened however, an ostium opening into the pulmonary trunk was evident. Histopathological investigation revealed that the intramural PDA resembled vascular tissue with a structure and architecture. The diagnosis was an intramural PDA, an extremely rarely reported type of PDA in the dog.

ABSTRACT

Background@#Patients with atopic dermatitis (AD) are vulnerable to xerosis due to impaired skin barrier function, which makes moisturizing essential. Recently, zinc-alpha-2 glycoprotein (ZAG) has appeared to modulate the skin barrier function in AD, and has been proposed as a potential therapeutic molecule in AD. @*Objective@#This study aimed to evaluate the effects of a ZAG-containing moisturizer on restoration of the skin barrier and clinical improvement of AD. @*Methods@#In this randomized, double-blind study, 42 patients (average age, 26.5 years) with mild-to-moderate AD were enrolled. The subjects were divided into two groups, ZAG-containing moisturizer or control, in which the intervention or control were applied twice a day for 4 weeks. The primary outcome was a change in the eczema area and severity index (EASI) after 4 weeks, and the secondary outcome included the transepidermal water loss (TEWL), corneometer, visual assessment score (VAS) for pruritus and sleep disturbance, and investigator’s global assessment (IGA). @*Results@#ZAG-containing moisturizer was well-tolerated, with a significant decrease in the EASI score compared to the control group after 4 weeks of application (p<0.05). As objective assessments of skin barrier function, TEWL also showed a significant, rapid decrease in the ZAG group compared to the control group after 2 weeks of application (p<0.05). A significant improvement in AD symptoms was observed at 4 weeks, such as the VAS score for pruritus and sleep disturbance, and IGA. Conclusion: The moisturizer containing ZAG (By the doctor Ato repair cream , Whitecospharm, Korea) effectively restored the function of the skin barrier, which led to a relief in the signs and symptoms of AD.

ABSTRACT

STUDY DESIGN: Retrospective, single-center study. PURPOSE: We aimed to determine the perioperative complications of oblique lumbar interbody fusion (OLIF) as a first-stage procedure in combined anterior and posterior operation for adult spinal deformity (ASD) along with sagittal imbalance. Specifically, we aimed to identify the radiological and clinical types of perioperative surgical complications and the factors affecting these complications. OVERVIEW OF LITERATURE: OLIF has recently gained popularity, and there are several reports of good outcomes and only a few of complications with OLIF; however, a few studies have focused on the perioperative surgical complications of ASD along with sagittal imbalance. METHODS: The perioperative period was a 1-week interval between the anterior and posterior procedures. All patients underwent simple radiography and magnetic resonance imaging preoperatively and postoperatively. Cage placement was evaluated for displacement (i.e., subsidence and migration) and vertebral body fracture. Clinical patient complaints were evaluated perioperatively. Student t-test was used for data analysis. RESULTS: A total of 46 patients were included, totaling 138 fusion segments. A week after OLIF, 14 patients/33 segments (30.4%/23.9%) demonstrated endplate injury-associated cage placement change. Subsidence was the most common cage placement-related complication. As compared with patients without endplate injury, those with endplate injuries showed significantly larger correction angles and a higher proportion of them had larger height cages than the disk height in the full-extension lateral view. Although 32.6% of the patients experienced perioperative clinical complications, they were relatively minor and transient. The most common complication was severe postoperative pain (Visual Analog Scale score of >7), and hip flexor weakness spontaneously resolved within 1 week. CONCLUSIONS: OLIF yielded more than expected endplate injuries from treatment modalities for ASD along with sagittal imbalance. Therefore, surgeons should be cautious about endplate injury during OLIF procedures. It is difficult to accomplish lordosis correction via OLIF alone; therefore, surgeons should not attempt this impractical correction goal and insert an immoderate cage.

ABSTRACT

PURPOSE: We evaluated the results of allograft reconstruction following wide resection of malignant bone tumors in long bone, retrospectively. MATERIALS AND METHODS: Seven patients were included. The mean age was 44 years old. Male was 4 cases, and female was 3 cases. Mean follow-up period was 38 months. The mean Musculoskeletal Tumor Society (MSTS) score at final follow-up was evaluated. Postoperative complications were evaluated via periodic radiologic follow-up. Oncologic results were analyzed at final follow-up. RESULTS: The primary malignancies occurred at femur in 5 cases, humerus in 1 case and tibia in 1 case. Pathologic diagnoses were osteosarcoma in 4 cases, multiple myeloma in 2 cases and adamantinoma in 1 case. Mean length of allograft was 165 mm. Fixations of allograft were intramedullary nailing with additional plate in 4 cases, intramedullary nailing in 2 cases, and screw fixation in 1 case. Mean time to union was 14.5 weeks. Mean MSTS score at final follow-up was 20 (67%). Postoperative complications were nonunion in 3 cases, implant failure in 1 case, and infection in 1 case. Oncologic outcomes were continuous disease free in 5 cases and alive with disease in 2 cases at final follow-up. Autologous bone graft and hemi-cortical onlay graft were performed in 2 cases of nonunion. CONCLUSION: Allograft reconstruction following wide resection of malignant bone tumors in long bone was effective surgical option. However, the possibility of nonunion between host bone and allograft should be considered.

ABSTRACT

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) is known to be a major adverse predictor in diabetes mellitus (DM) patients undergoing percutaneous coronary intervention (PCI). It is expected that the use of newer-generation drug-eluting stents (DES) would improve clinical outcomes in these patients. We evaluated the impact of CKD on clinical outcomes in diabetic patients undergoing PCI using newer-generation DES in a real-world setting. SUBJECTS AND METHODS: A total of 887 patients who underwent PCI with newer-generation DES and who had a history of DM or HbA1c >6.5% at the time of hospitalization were analyzed. These patients were divided into groups without CKD (n=549) and with CKD (n=338). Among survivors at discharge, a patient-oriented composite outcome (POCO) including all-cause mortality, myocardial infarction (MI), and revascularization was evaluated, together with a device-oriented composite outcome (DOCO) including cardiac death, target vessel-related MI, and target lesion revascularization at a follow-up period of one year. RESULTS: The incidence of POCO (5.4% vs. 14.0%, log-rank p<0.001) and DOCO (1.1% vs. 4.1%, log-rank p<0.001) was higher in patients with CKD. According to multivariate analysis, which was adjusted for baseline differences in demographic, clinical, and angiographic factors, the presence of CKD was an independent predictor of POCO (hazard ratio [HR]: 1.82, 95% confidence interval [CI]: 1.07 to 3.12), but not of DOCO (HR 2.08, 95% CI: 0.69-6.28). CONCLUSION: In DM patients, CKD is an independent and powerful predictor of patient-related outcomes, but not of device-related outcomes in the era of newer-generation DES.

ABSTRACT

PURPOSE: The aim of this study was to compare the changes in retentive force of stud attachments for implant overdentures by in vitro 2-year-wear simulation. MATERIALS AND METHODS: Three commercially available attachment systems were investigated: Kerator blue, O-ring red, and EZ lock. Two implant fixtures were embedded in parallel in each custom base mounting. Five pairs of each attachment system were tested. A universal testing machine was used to measure the retentive force during 2500 insertion and removal cycles. Surface changes on the components were evaluated by scanning electron microscopy (SEM). A Kruskal-Wallis test, followed by Pairwise comparison, was used to compare the retentive force between the groups, and to determine groups that were significantly different (alpha.05). After 2500 insertion and removal cycles, the highest retention loss was recorded for O-ring, and no significant difference between Kerator and EZ lock (P>.05). Also, Kerator showed the highest retentive force, followed by EZ lock and O-ring, after 2500 cycles (P<.05). Based on SEM analysis, the polymeric components in O-ring and Kerator were observed to exhibit surface wear and deformation. CONCLUSION: After 2500 insertion and removal cycles, all attachments exhibited significant loss in retention. Mechanism of retention loss can only be partially explained by surface changes.

ABSTRACT

For the rehabilitation of fully edentulous patients, implant-supported removable partial dentures can be considered as one of the treatment options with complete dentures or implant-supported overdentures. If removable partial dentures are used in combination with a small number of implants placed in strategically important positions, it can offer additional stability, retention and support through implants and reduce a burden of surgical procedures compared with fixed implant-supported prostheses with extensive implant placement. Moreover, the economical benefit can be expected as well. The purpose of this case report is to present a treatment in which an implant-supported removable partial denture was fabricated considering residual alveolar bone status and demands after teeth loss in a patient who had been using a distal extension removable partial denture for a long period of time. In anterior area, fixed prostheses were fabricated with implant placement and in posterior area, short implants provide only support for the removable partial denture. In addition, denture base and clasp were made of thermoplastic acrylic resin. Finally, functionally and aesthetically satisfying treatment results can be achieved.

ABSTRACT

BACKGROUND: Neck circumference, as a predicator of obesity, is a well-known risk factor for obstructive sleep apnea and cardiovascular diseases. However, little research exists on neck length associated with these factors. This study explored the association of neck length with sleep and cardiovascular risk factors by measuring midline neck length (MNL) and lateral neck length (LNL). METHODS: We examined 240 patients aged 30 to 75 years who visited a health check-up center between January 2012 and July 2012. Patients with depressive disorder or sleep disturbance were excluded from this study. MNL from the upper margin of the hyoid bone to the jugular notch and LNL from the mandibular angle to the mid-portion of the ipsilateral clavicle were measured twice and were adjusted by height to determine their relationship with sleep and cardiovascular disease risk factors. RESULTS: Habitual snorers had shorter LNL height ratios (P = 0.011), MNL height ratios in men (P = 0.062), and MNL height ratios in women (P = 0.052). Those snoring bad enough to annoy others had shorter MNL height ratios in men (P = 0.083) and women (P = 0.035). Men with objective sleep apnea had longer distances from the mandible to the hyoid bone to the mandible (P = 0.057). Men with metabolic syndrome had significantly shorter LNL height ratios (P = 0.021), and women with diabetes, hyperlipidemia, and metabolic syndrome had shorter MNL height ratios (P < 0.05). CONCLUSION: This study shows that a short neck by measuring the MNL is probably associated with snoring. In addition, MNL is related to cardiovascular disease risk factors in women.

ABSTRACT

BACKGROUND: It has traditionally been known that there is normally a difference in blood pressure (BP) between the two arms; there is at least 20 mm Hg difference in the systolic blood pressure (SBP) and 10 mm Hg difference in the diastolic blood pressure (DBP). However, recent epidemiologic studies have shown that there are between-arm differences of 10 mm Hg. In women, 89.6% of patients had IAD in SBP of 10 mm Hg or IAD in DBP of > 10 mm Hg. Gangneung Asan Hospital clinical series of patients showed that the absolute IAD in SBP had a significant correlation with cardiovascular risk factors such as the 10-year Framingham cardiac risk scores and higher BP in men and higher BP in women. However, the absolute IAD in SBP and DBP had no significant correlation with the age, obesity, smoking, drinking, hyperlipidemia, diabetes, metabolic syndrome, and renal function. CONCLUSION: Our results showed that there were no significant between-arm differences in simultaneous BP measurements. It was also shown that most of the ambulatory patients without cardiovascular diseases had an IAD in SBP of < 10 mm Hg and an IAD in DBP of < 6 mm Hg.
