RESUMEN
Background@#COVID-19 and delayed hip surgery are well-known risk factors for thromboembolism in elderly patients.Case: We report the case of an 88-year-old female patient with COVID-19 and pulmonary thromboembolism (PTE) who underwent delayed hip surgery 21 days after the injury. Heparinization and inferior vena cava filters were used to treat and prevent PTE. Transesophageal echocardiography and extracorporeal membrane oxygenation (ECMO) sheaths were inserted as a precaution in case of emergencies during surgery; the procedure was performed without any specific event. @*Conclusions@#COVID-19-infected patients suffering from a hip fracture have a high risk of thromboembolism, and therefore, require utmost attention for appropriate evaluation and prevention.
RESUMEN
Background@#The optimal level of glycosylated hemoglobin (HbA1c) to prevent adverse clinical outcomes is unknown in patients with chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM). @*Methods@#We analyzed 707 patients with CKD G1-G5 without kidney replacement therapy and T2DM from the KoreaN Cohort Study for Outcome in Patients With Chronic Kidney Disease (KNOW-CKD), a nationwide prospective cohort study. The main predictor was time-varying HbA1c level at each visit. The primary outcome was a composite of development of major adverse cardiovascular events (MACEs) or all-cause mortality. Secondary outcomes included the individual endpoint of MACEs, all-cause mortality, and CKD progression. CKD progression was defined as a ≥50% decline in the estimated glomerular filtration rate from baseline or the onset of end-stage kidney disease. @*Results@#During a median follow-up of 4.8 years, the primary outcome occurred in 129 (18.2%) patients. In time-varying Cox model, the adjusted hazard ratios (aHRs) for the primary outcome were 1.59 (95% confidence interval [CI], 1.01 to 2.49) and 1.99 (95% CI, 1.24 to 3.19) for HbA1c levels of 7.0%–7.9% and ≥8.0%, respectively, compared with <7.0%. Additional analysis of baseline HbA1c levels yielded a similar graded association. In secondary outcome analyses, the aHRs for the corresponding HbA1c categories were 2.17 (95% CI, 1.20 to 3.95) and 2.26 (95% CI, 1.17 to 4.37) for MACE, and 1.36 (95% CI, 0.68 to 2.72) and 2.08 (95% CI, 1.06 to 4.05) for all-cause mortality. However, the risk of CKD progression did not differ between the three groups. @*Conclusion@#This study showed that higher HbA1c levels were associated with an increased risk of MACE and mortality in patients with CKD and T2DM.
RESUMEN
Background@#Although most studies focused on the alignment or union of the tibia in same-level distal third tibiofibular fractures, the outcome of a concomitant fibular fracture is generally regarded as being of secondary importance in the literature. This study aimed to assess the outcomes of fibular fractures in same-level distal third tibiofibular fractures. @*Methods@#In this retrospective study, we enrolled 111 patients with same-level distal third tibiofibular fractures treated at our institute between January 2016 and August 2020. Tibial fractures were stabilized with intramedullary nailing, and the cases were divided into two groups based on whether they additionally underwent fibular fixation (group 1, 57 cases) or not (group 2, 54 cases). Clinical and radiographic outcomes were used for the evaluation of tibial and fibular alignments, union of the tibia and fibula, number of interlocking screws in the distal tibial fragment, range of motion of the ankle joint, and complications. @*Results@#No statistically significant differences in the tibial union rate or mean tibial alignment were observed between the two groups on either the immediate postoperative or final radiographs. The fibular union rate in group 1 was significantly higher than that in group 2 (fibular nonunion, 0 vs. 15; p < 0.001). Statistically significant differences in fibular displacement were observed on immediate postoperative radiographs between patients with fibular union and those without it. At the final follow-up, the mean range of ankle motion and lower extremity functional scale scores did not differ between the two groups. @*Conclusions@#Regardless of whether fibular fixation was performed, the overall tibial alignment with intramedullary nailing was well restored and the union rate of the tibia was comparable in the two groups. Fibular nonunion is not uncommon in unfixed fibula fractures. Displacement of the fibula as seen on immediate postoperative radiographs was related to fibular nonunion.
RESUMEN
Background@#Increasing longevity has caused the very old population to become the fastest-growing segment. The number of centenarians (over 100 years old) is increasing rapidly. Fractures in the elderly lead to excessive medical costs and decreased quality of life with socioeconomic burdens. However, little research has thoroughly examined the functional outcomes and mortality of hip fractures in centenarians. @*Methods@#This is a retrospective observational study. Sixty-eight centenarian hip fracture patients were admitted to the 10 institutions from February 2004 to December 2019. Fifty-six patients with 1-year follow-up were finally included. The following data were obtained: sex, age, body mass index, Charlson comorbidity index value on the operation day, Koval’s classification for ambulatory ability, type of fracture, the time interval from trauma to surgery, American Society of Anesthesiologists grade, surgery-related complications, and duration of hospital stay. Postoperative Koval’s classification (at 1 year after surgery) and information about death were also collected. Multivariate analysis was performed to analyze the risk factors affecting mortality 1 year after surgery. @*Results@#Mortality rates were 26.8% at 6 months and 39.3% at 1 year. The 90-day mortality was 19.6%, and one of them (2.1%) died in the hospital. The 1-year mortality rates for the community ambulatory and non-community ambulatory groups were 29% and 52%, respectively. Only 9 (16.1%) were able to walk outdoors 1 year after surgery. The remaining 47 patients (83.9%) had to stay indoors after surgery. Multivariate analysis demonstrated that the pre-injury ambulatory level (adjusted hazard ratio, 2.884; p = 0.034) was associated with the risk of mortality. @*Conclusions@#We report a 1-year mortality rate of 39.3% in centenarian patients with hip fractures. The risk factor for mortality was the pre-injury ambulatory status. This could be an important consideration in the planning of treatment for centenarian hip fracture patients.
RESUMEN
Background@#The purpose of this study was to investigate the demographic factors and radiological characteristics of lesser trochanter splitting (LTS) irreducible intertrochanteric fractures and to report the clinical results of patients who underwent open reduction and internal fixation using dynamic hip screws (DHS). @*Methods@#Inclusion criteria were as follows: AO/Orthopedic Trauma Association type 31A1.2, a fracture line originating from the outside of the greater trochanter that passes through the lesser trochanter, and patients who were followed up for more than 1 year with a confirmed presence or absence of bone union. A total of 13 cases were identified, accounting for 3.1% (13/416 intertrochanteric fractures). Patients were classified according to posterior sagging of the distal shaft fragment relative to the headneck fragment (posterior sagging group, 6; non-sagging group, 7). Demographic data, comorbidities, injury mechanism, type of anesthesia, operation time, blood loss, tip-apex distance, reduction quality, leg length discrepancy (> 5 mm), long lesser trochanter sign, postoperative complications, and presence of bony union were obtained by reviewing medical records and radiological findings. @*Results@#The mean age of the patients was 50.4 ± 10.4 years, and 12 were men. Except for 1 case (slip down), all were induced by high-energy trauma. According to the grade of reduction quality, 5 cases (38.5%) had good reduction quality and 8 cases (61.5%) had acceptable reduction quality. There were no postoperative complications, and bony union was observed in all cases. The long lesser trochanter sign was observed in 5 cases (38.5%) and leg length discrepancy greater than 5 mm was not observed. Compared with the non-sagging group, the posterior sagging group had more head-neck fragments containing more than 1/2 of the lesser trochanter length, longer operation time, and more blood loss (p < 0.05). Compared to the non-sagging group, the posterior sagging group had worse reduction quality and more long lesser trochanter signs (p < 0.05). @*Conclusions@#Open reduction and internal fixation using DHS for the LTS irreducible intertrochanteric fractures can achieve good clinical and radiological outcomes. However, in the posterior sagging type, reduction can be more difficult with a longer operation time and higher likelihood of blood loss.
RESUMEN
Methods@#Thirty-one patients with multilevel cervical spondylotic myelopathy who required C6–C7 level decompression surgery were operated and followed up for 24 months. One group (15 patients) received C7 arcocristectomy without laminoplasty, and the other group (16 patients) received C7 laminoplasty. Flexion, neutral, and extension angles were measured using the Cobb method at C2–C7 to evaluate preoperative and postoperative radiographic parameters. Range of motion (ROM), ROM preservation rate of the cervical spine, C2–C7 sagittal vertical axis (SVA), and T1 slope were measured using C-spine lateral X-ray. The Visual Analog Scale (VAS) and modified Japanese Orthopedic Association (JOA) score were used to compare preoperative and postoperative clinical symptoms. @*Results@#Flexion, neutral, extension angles of the cervical spine, C2–C7 SVA, T1 slope, ROM, ROM preservation rate, and modified JOA score were not significantly different between the two groups (p>0.05). In the C7 arcocristectomy group, the average postoperative VAS for axial neck pain was increased in 13.3% (2/15) of the patients, whereas in the C7 laminoplasty group, the average postoperative VAS was increased in 43.8% (7/16) of the patients (p=0.018). @*Conclusions@#C7 arcocristectomy, which preserves the C7 spinous process and posterior structures, is a useful technique for relieving axial neck pain.
RESUMEN
Background@#The position of the eyebrows is critical when planning blepharoptosis surgery. However, insufficient scholarly attention has been paid to the details of postoperative eyebrow height changes at each anatomical landmark. This study investigated the effect of blepharoptosis surgery on brow height and evaluated the change in brow position. @*Methods@#After a retrospective review of 247 patients, this study analyzed 53 patients (106 eyelids) who underwent levator and Müller’s complex advancement between March 2010 and January 2022. Brow heights were measured from the distance between the upper brow margin of each landmark and horizontal line of pupillary center on a digital photograph. @*Results@#The mean change of eyebrow lowering was 1.54 mm (P<0.001) at the medial canthus, 1.29 mm (P<0.001) at the medial limbus, 1.44 mm (P<0.001) at the center of the pupil, 1.40 mm (P<0.001) at the lateral limbus, 1.15 mm (P=0.001) at the lateral canthus, and 0.75 mm (P=0.021) at the lateral eyebrow end. The brow change was most prominent at medial canthus and least prominent at the lateral brow end. The preoperative brow position was only statistically significant factor predicting brow height descent after surgery according to multiple linear regression analysis (R2=0.305, B=–0.375, P<0.001). @*Conclusions@#The eyebrows lowered in most patients after blepharoptosis surgery. The preoperative brow position is the most important factor in predicting the change in brow height after blepharoptosis surgery.
RESUMEN
Purpose@#Perioperative transfusion is reported to be an independent risk factor not only for postoperative complications but also for early recurrence of periampullary carcinoma after pancreaticoduodenectomy (PD). The purpose of this study was to evaluate the safety and efficacy of ferric carboxymaltose (FCM) in reducing the need for perioperative transfusion in iron deficiency anemia patients scheduled for PD. @*Methods@#Twenty-two male patients (hemoglobin [Hb] 7 to <13 g/dL) and 18 female patients (Hb 7 to <12 g/dL) were enrolled in the study group and administered FCM 1–3 weeks before PD. The perioperative transfusion rate was the primary endpoint; morbidity, length of postoperative hospital stay, change in hematological parameters after FCM injection, and adverse effects of FCM were also investigated. @*Results@#The perioperative transfusion rate of the study group was 22.5% (9 of 40). Hb level was significantly higher on the day of the operation compared to baseline (P < 0.001). Levels of Hb, transferrin saturation, and ferritin were higher at the follow-up compared to baseline (P = 0.008, P = 0.033, and P < 0.001, respectively). @*Conclusions@#FCM administration was associated with a reduced need for perioperative transfusion and can safely stabilize hematological parameters.
RESUMEN
Purpose@#The efficacy of the Mindful Self-Compassion (MSC) for Healthcare Communities program has not been verified. This study aims to evaluate the feasibility and efficacy of the online MSC for Healthcare Communities program on burnout, stress-related health, and resilience among surgical trainees. @*Methods@#A single-arm pilot study was conducted at a tertiary referral academic hospital in Korea. Surgical trainees were recruited through flyer postings; therefore, a volunteer sample was used. Thus, 15 participants participated, among whom 9 were women and 11 were doctor-residents. The Self-Compassion for Healthcare Communities (SCHC) program was conducted from September to October 2021 via weekly online meetings (1 hour) for 6 weeks. The efficacy of the program was evaluated using validated scales for burnout, stress, anxiety, depression, self-compassion, and resilience before and after the intervention and 1 month later. @*Results@#The results showed significantly reduced burnout, anxiety, and stress scores. After the program, high emotional exhaustion and depersonalization rates decreased, and personal accomplishment increased. Eight participants showed reduced anxiety postintervention, and 9 showed reduced stress. Improvements were observed between pre- and postintervention in resilience, life satisfaction, and common humanity. Changes in self-compassion predicted higher gains in resilience and greater reductions in burnout and stress. @*Conclusion@#The SCHC is a feasible and effective program to improve resilience, self-compassion, and life satisfaction and reduce stress, anxiety, depression, and burnout in surgical trainees. This study highlights the need to include specific mental health programs in surgical training to improve trainees’ well-being.
RESUMEN
Background@#Surgical resection is the standard treatment for early-stage lung cancer. Since postoperative lung function is related to mortality, predicted postoperative lung function is used to determine the treatment modality. The aim of this study was to evaluate the predictive performance of linear regression and machine learning models. @*Methods@#We extracted data from the Clinical Data Warehouse and developed three sets: set I, the linear regression model; set II, machine learning models omitting the missing data: and set III, machine learning models imputing the missing data. Six machine learning models, the least absolute shrinkage and selection operator (LASSO), Ridge regression, ElasticNet, Random Forest, eXtreme gradient boosting (XGBoost), and the light gradient boosting machine (LightGBM) were implemented. The forced expiratory volume in 1 second measured 6 months after surgery was defined as the outcome. Five-fold cross-validation was performed for hyperparameter tuning of the machine learning models. The dataset was split into training and test datasets at a 70:30 ratio. Implementation was done after dataset splitting in set III. Predictive performance was evaluated by R2 and mean squared error (MSE) in the three sets. @*Results@#A total of 1,487 patients were included in sets I and III and 896 patients were included in set II. In set I, the R2 value was 0.27 and in set II, LightGBM was the best model with the highest R2 value of 0.5 and the lowest MSE of 154.95. In set III, LightGBM was the best model with the highest R2 value of 0.56 and the lowest MSE of 174.07. @*Conclusion@#The LightGBM model showed the best performance in predicting postoperative lung function.
RESUMEN
Objective@#The purpose of this study was to examine whether attachment insecurity, stigma, and certain demographic and medical factors predict depression and anxiety in people living with HIV (PLWH). @*Methods@#Participants were 147 PLWH who visited the outpatient infection clinic in Kyungpook National University Hospital (KNUH; Daegu, South Korea) between June 2020 and January 2021. We measured HIV-related stigma, attachment anxiety and avoidance, depressive symptoms, and anxiety symptoms. @*Results@#Logistic regression analysis showed that unemployment, longer time receiving antiretroviral therapy, higher attachment avoidance, and higher attachment anxiety were significant predictors of depression. Results also showed that longer time receiving antiretroviral therapy, higher attachment anxiety, and concern with public attitudes were significant predictors of anxiety. @*Conclusion@#In addition to education to reduce public stigma, interventions to reduce PLWH’s self-stigma should continue. We suggest attachment-based psychotherapy as an effective intervention to improve PLWH’s mental health.
RESUMEN
Background@#Angiotensin-converting enzyme inhibitor (ACEi) inhibits the catalysis of angiotensin I to angiotensin II and the degradation of substance P (SP) and bradykinin (BK). While the possible relationship between ACEi and SP in nociceptive mice was recently suggested, the effect of ACEi on signal transduction in astrocytes remains unclear. @*Objectives@#This study examined whether ACE inhibition with captopril or enalapril modulates the levels of SP and BK in primary cultured astrocytes and whether this change modulates PKC isoforms (PKCα, PKCβI, and PKCε) expression in cultured astrocytes. @*Methods@#Immunocytochemistry and Western blot analysis were performed to examine the changes in the levels of SP and BK and the expression of the PKC isoforms in primary cultured astrocytes, respectively. @*Results@#The treatment of captopril or enalapril increased the immunoreactivity of SP and BK significantly in glial fibrillary acidic protein-positive cultured astrocytes. These increases were suppressed by a pretreatment with an angiotensin-converting enzyme.In addition, treatment with captopril increased the expression of the PKCβI isoform in cultured astrocytes, while there were no changes in the expression of the PKCα and PKCε isoforms after the captopril treatment. The captopril-induced increased expression of the PKCβI isoform was inhibited by a pretreatment with the neurokinin-1 receptor antagonist, L-733,060, the BK B 1 receptor antagonist, R 715, or the BK B 2 receptor antagonist, HOE 140. @*Conclusions@#These results suggest that ACE inhibition with captopril or enalapril increases the levels of SP and BK in cultured astrocytes and that the activation of SP and BK receptors mediates the captopril-induced increase in the expression of the PKCβI isoform.
RESUMEN
Purpose@#To investigate the long-term clinical course and prognostic factors of branch retinal artery occlusion (BRAO). @*Methods@#The medical records of patients diagnosed with BRAO were reviewed retrospectively. Visual acuity (VA) and central retinal thickness (CRT) at diagnosis were compared with those measured at the final visit. Patients with a decimal VA ≥ 0.6 (good prognosis group) were compared with those with a decimal VA ≤ 0.5 (poor prognosis group) at the final visit. @*Results@#Fifty-five patients were enrolled and the mean follow-up period was 45.8 ± 27.8 months. The mean logarithm of minimum angle of resolution improved from 0.53 ± 0.57 at diagnosis to 0.36 ± 0.61 at the final visit (p = 0.026). The decimal VA was ≤ 0.1 in 13 (23.6%) patients, ≥ 0.2 and ≤ 0.5 in 16 (29.1%) patients, and ≥ 0.6 in 26 (47.3%) patients at diagnosis; the respective values were 9 (16.4%), 8 (14.5%), and 38 (69.1%) at the final visit. The mean CRT significantly decreased from 273.9 ± 34.7 µm at diagnosis to 248.9 ± 27.0 µm at the final visit (p < 0.001). The poor prognosis group (n = 17) was older (p = 0.044) and had a higher incidence of papillomacular bundle involvement (p < 0.001) than the good prognosis group (n = 38). @*Conclusions@#Patients with BRAO generally showed relatively favorable long-term outcomes. However, the final VA was ≤ 0.1 in 16.4% of them, suggesting the need for further treatment modalities to improve the outcome of patients with a poor prognosis.
RESUMEN
Purpose@#To evaluate the clinical course of neovascular age-related macular degeneration (nAMD) that has shown limited response to ranibizumab and aflibercept. @*Methods@#This retrospective study included 14 eyes with nAMD that showed a limited response to initial treatment using ranibizumab and aflibercept. The changes in visual acuity (VA) during the follow-up period and the incidence and timing of VA deterioration to the level of 0.1 or worse were identified. In cases involving bevacizumab treatment, the follow-up duration and the proportion of patients maintaining a VA of 0.2 or better were identified. @*Results@#During the mean 43.3 ± 33.2 months of follow-up, the VA deteriorated significantly from a mean logarithm of minimum angle of resolution (logMAR) of 0.42 ± 0.34 at diagnosis to 0.91 ± 0.68 at the final follow-up (p = 0.021). A logMAR of 0.3 or greater degree of VA deterioration was noted in six eyes (42.9%). Among the 13 eyes exhibiting a VA of 0.2 or better after the initial treatment, a deterioration to a VA of 0.1 or worse was noted in 6 eyes (46.2%) at a mean 29.7 ± 18.3 months. In eight eyes undergoing bevacizumab treatment, four eyes (50.0%) maintained 0.2 or better VA during the 51.4 ± 35.5 months of follow-up. @*Conclusions@#The clinical course of patients with limited response to ranibizumab and aflibercept was generally unfavorable. However, a relatively long period was required for the deterioration in VA to reach 0.1 or worse. In addition, 0.2 or better VA was maintained in approximately half of the patients.
RESUMEN
Post-traumatic seizures and epilepsy are major complications that increase the mortality rate among patients with traumatic brain injury (TBI) and hinder functional recovery. It is important to establish prophylaxis and treatment strategies for high-risk patients. The use of antiseizure medications may not only adversely affect the cognitive function following TBI but also may be associated with a worse rehabilitation outcome.Current Concepts: The level of evidence in the current international guidelines related to the prophylaxis and management of post-traumatic seizure is not robust. Furthermore, the use of antiseizure medications after TBI remains unclear, indicating substantial variations in clinical practice.Discussion and Conclusion: Prophylactic antiseizure medications can reduce the risk of early seizures and partially prevent the secondary injury process of TBI; however, they do not seem to inhibit epileptogenesis. Therefore, if the benefits of preventing early seizures outweigh the potential risks associated with antiseizure medication, it is recommended to use them for a short period of about one week after the injury. Then, it is not recommended to continue using them routinely without considering the individual risk of seizure recurrence and potential adverse effects of long-term use. The treatment duration of anticonvulsant in patients with post-traumatic epilepsy should also be determined based on the individual risk of seizure recurrence, and the decision should take into account the opinions of both the patient and the caregiver, while considering not only the potential benefits but also the risks associated with long-term use.
RESUMEN
Background@#Sarcopenia can be associated with the disease etiologies other than degenerative processes, such as neurologic disease including cerebral palsy, myelomeningocele, or Duchenne muscular dystrophy, even in children. Although the relationship between neurologic disease and scoliosis or ambulatory function is known, the mediators affecting scoliosis or gait function in these patients are unclear, an example might be sarcopenia. This study aimed to assess the degree of sarcopenia in young patients with neurologic diseases using computed tomography (CT), and analyze the correlation between sarcopenia and scoliosis or ambulatory function. @*Methods@#Pediatric and young adult patients (≤ 25 years old) who underwent whole-spine or lower-extremity CT were retrospectively included. From bilateral psoas muscle areas (PMAs) at the L3 level, the psoas muscle z-score (PMz) and psoas muscle index [PMI = PMA/(L3 height) 2 ] were calculated. The t-test, Fisher’s exact test, and logistic regression analyses were performed. @*Results@#A total of 121 patients (56 men, mean age 12.2 ± 3.7 years) were included with 79 neurologic and 42 non-neurologic diseases. Patients with neurologic diseases had lower PMz (P = 0.013) and PMI (P = 0.026) than patients without. In neurologic disease patients, severe scoliosis patients showed lower PMz (P < 0.001) and PMI (P = 0.001). Non-ambulatory patients (n = 42) showed lower BMI (β = 0.727, P < 0.001) and PMz (β = 0.547, P = 0.025). In non-ambulatory patients, patients with severe scoliosis also showed lower PMz (P < 0.001) and PMI (P = 0.004). @*Conclusion@#Patients with neurologic diseases could have sarcopenia even in young age.Psoas muscle volume was also associated with ambulatory function in these patients.Sarcopenia was more severe in severe scoliosis patients in the non-ambulatory subgroup.
RESUMEN
Background@#This study aimed to 1) assess the effect of total hip arthroplasty (THA) on coronal limb alignment, namely, the hip–knee–ankle angle (HKA), 2) identify factors that determine changes in the HKA, and 3) determine whether alignment changes influence the knee joint space width. @*Methods@#We retrospectively evaluated 266 limbs of patients who underwent THA. Three types of prostheses with neck shaft angles (NSAs) of 132°, 135°, and 138° were used. Several radiographic parameters were measured in the preoperative and final radiographs (at least 5 years after THA). A paired t-test was used to confirm the effect of THA on HKA change.Multiple regression analysis was performed to identify radiographic parameters related to HKA changes following THA and changes in knee joint space width. Subgroup analyses were performed to reveal the effect of NSA change on the HKA change, and the proportion of total knee arthroplasty usage and changes in radiographic parameters between maintained joint space and narrowed joint space groups were compared. @*Results@#The preoperative mean HKA was 1.4° varus and increased to 2.7° varus after THA.This change was related to changes in the NSA, lateral distal femoral angle, and femoral bowing angle. In particular, in the group with a decrease in NSA of > 5°, the preoperative mean HKA was largely changed from 1.4° varus to 4.6° varus after THA. The prostheses with NSA of 132° and 135° also led to greater varus HKA changes than those with an NSA of 138°. Narrowing of the medial knee joint space was related to changes in the varus direction of the HKA, decrease in NSA, increase in femoral offset. @*Conclusion@#A large reduction in NSA can lead to considerable varus limb alignment after THA, which can have adverse effects on the medial compartment of the ipsilateral knee.
RESUMEN
Background/Aims@#Patients with inflammatory bowel disease (IBD) are diagnosed with ankylosing spondylitis (AS) often. However, the disease course of patients with both IBD and AS is not well understood. This study aims to evaluate the effect of concomitant AS on IBD outcomes. @*Methods@#Among the 4,722 patients with IBD who were treated in 3 academic hospitals from 2004 to 2021, 55 were also diagnosed with AS (IBD-AS group). Based on patients’ electronic medical records, the outcomes of IBD in IBD-AS group and IBD group without AS (IBD-only group) were appraised. @*Results@#The proportion of patients treated with biologics or small molecule therapies was significantly higher in IBD-AS group than the proportion in IBD-only group (27.3% vs. 12.7%, P= 0.036). Patients with both ulcerative colitis and AS had a significantly higher risk of biologics or small molecule therapies than patients with only ulcerative colitis (P< 0.001). For univariable logistic regression, biologics or small molecule therapies were associated with concomitant AS (odds ratio, 4.099; 95% confidence interval, 1.863–9.021; P< 0.001) and Crohn’s disease (odds ratio, 3.552; 95% confidence interval, 1.590–7.934; P= 0.002). @*Conclusions@#Concomitant AS is associated with the high possibility of biologics or small molecule therapies for IBD. IBD patients who also had AS may need more careful examination and active treatment to alleviate the severity of IBD.
RESUMEN
Background@#Laminoplasty is a common and effective surgery for decompression of the spinal cord in multilevel cervical myelopathy. The midline splitting technique (MST) and the unilateral open door technique (UODT) are the two most commonly performed laminoplasty techniques with continuous debate on which is preferable. This study aimed to add light to the matter by comparing and exploring the possible causes of different outcomes. @*Methods@#A total of 101 patients who underwent laminoplasty for degenerative cervical myelopathy were included in this study.Radiographic measurements including C2–7 Cobb angle, C2–7 range of motion (ROM), Pavlov ratio of the most compressed level, and canal area with diameter were compared. Modified Japanese Orthopedic Association (mJOA) score and complications including C5 palsy, axial neck pain, hinge fractures, and spacer displacement were also compared. Statistical analysis was performed using independent samples t-test, chi-square test, Fisher’s exact test, and linear mixed model. @*Results@#C2–7 ROM, canal diameter, Pavlov ratio, and mJOA score did not demonstrate differences between the two techniques.The UODT group had greater postoperative canal expansion but had more loss of C2–7 lordosis than did the MST group. Of the complications, hinge fractures were more common in the UODT group, with more loss of C2–7 lordosis in patients with hinge fractures. On the other hand, spacer displacement occurred only in the MST group, with lesser canal expansion in patients with spacer displacement. @*Conclusions@#The two laminoplasty techniques both demonstrated effectiveness in treating patients with multilevel cervical myelopathy. However, care should be given to avoid hinge fractures and spacer displacement since both can possibly lead to unfavorable outcomes.
RESUMEN
Nevus sebaceus is a hamartomatous lesion characterized by epidermal, follicular, sebaceus, and apocrine gland abnormalities. Approximately 25% of affected individuals may develop benign or malignant secondary neoplasms within the preceding nevus sebaceus. Primary cutaneous apocrine carcinoma (PCAC) is a rare malignant skin tumor affecting elderly adults in their sixth decade of life. Histologically, PCAC appears as a dermal tumor displaying apocrine differentiation with decapitation secretion and malignant features. Secondary malignancy arising from nevus sebaceus is a rare complication, especially for apocrine carcinoma. To date, approximately 200 cases of PCAC have been reported in the literature, and only a few cases have developed PCAC on the scalp. Very few cases (approximately only 12) of PCACs developing in nevus sebaceus have been reported. Here, we report an extremely rare case of the coexistence of PCAC and syringocystadenoma papilliferum arising within nevus sebaceus of the scalp.
