ABSTRACT

A short femoral stem (type 1 cementless stem) is being increasingly used to perform total hip arthroplasty; however, various types of intra- or postoperative periprosthetic fractures have been reported in recent times. A 66-year-old woman with a history of bilateral total hip arthroplasties using a type 1B femoral stem was admitted 2 months post-operation for a Vancouver type C periprosthetic fracture. She underwent open reduction and internal fixation; however, we observed recurrent non-union and plate breakage at the same site. In this case report, we discuss the factors associated with treatment failure in patients with a Vancouver type C periprosthetic fracture following type 1 femoral stem im-plantation.

ABSTRACT

Although vascular injuries associated with femoral intertrochanteric fractures have been reported infrequently, bleeding due to vascular injury can lead to severe complications that can be potentially life and limb-threatening. The authors report a case of an injury of the ascending branch of the lateral femoral convolutional artery in a patient who underwent surgical treatment for a femoral intertrochanteric fracture. Vascular injury occurred due to the sharp margin of displaced lesser trochanter five weeks after surgery. Percutaneous transcatheter embolization was done and improved without additional complications. Therefore, the surgeons need to be aware of possible associated vascular injuries caused by displaced lesser trochanter fragments in femoral intertrochanteric fractures.

ABSTRACT

A 12-year nationwide survey (2008-2019) was performed to investigate the prevalence of Enterobius vermicularis infection among preschool children in Seoul, 4 large cites (Busan, Incheon, Daegu, and Ulsan), and 9 provinces (grouped into 5 localities) in the Republic of Korea (=Korea). The survey was carried out once a year by 16 regional offices of the Korea Association of Health Promotion. The cello-tape perianal swab method (1 smear per child) was applied to detect eggs of E. vermicularis and other helminths. According to the results, the egg positive rate of E. vermicularis infection in 2008-2009 was 1.8-2.0%, but it decreased gradually to 0.6% in 2019 (P<0.05). The prevalence was significantly higher in boys (0.7-5.0%, mean 1.8%) than in girls (0.5-2.8%, mean 1.3%) (P<0.05). The 2 most southern localities, Jejudo (Province) and Jeolla-do (inclusive of Jeollabuk-do and Jeollanam-do) and a mid-western province, Gyeonggi-do, revealed higher prevalences, whereas Seoul and Gangwon-do showed lower prevalences. The results indicate that a low-grade prevalence of E. vermicularis infection (less than 4%) has been maintained for the recent 12 years among preschool children in Korea. Continuous monitoring of enterobiasis in the child age group is necessary in Korea.

ABSTRACT

Background@#We aimed to investigate the analgesic efficacy of an erector spinae plane block (ESPB) in immediate breast reconstruction (IBR) with a tissue expander. @*Methods@#Adult women undergoing IBR with a tissue expander after mastectomy were randomly assigned to either intravenous patient-controlled analgesia (IV-PCA) alone (group P) or IV-PCA plus ESPB (group E). The primary outcome was the total amount of opioid consumption during 24 hours postoperatively between the two groups. Secondary outcomes were patient satisfaction, pain score at rest and on shoulder movement using numerical rating scale, incidences of postoperative nausea and vomiting (PONV), and a short form of the brief pain inventory (BPI-SF) at 3 and 6 months after surgery between the groups. @*Results@#Fifty eight patients completed the study. At 24 hours postoperatively, total opioid consumption was significantly less in group E than in group P (285.0 ± 92.0, 95% confidence interval [CI]: 250.1 to 320.0 vs. 223.2 ± 83.4, 95% CI: 191.5 to 254.9, P = 0.005). Intraoperative and cumulative PCA fentanyl consumption at 3, 6, 9, and 24 hours were also less in group E than in group P (P = 0.004, P = 0.048, P = 0.020, P = 0.036, and P < 0.001, respectively). Patient satisfaction was higher in group E (6.9 ± 1.8 vs. 7.8 ± 1.4, P = 0.042). The incidences of PONV was similar. @*Conclusions@#The ESPB decreased postoperative opioid consumption and increased patient satisfaction without significant complications after IBR with a tissue expander after mastectomy.

ABSTRACT

Background@#Iliotibial band friction syndrome (ITBFS) is a common disorder of the lateral knee. Previous research has reported that the iliotibial band (ITB) thickness (ITBT) is correlated with ITBFS, and ITBT has been considered to be a key morphologic parameter of ITBFS. However, the thickness is different from inflammatory hypertrophy. Thus, we made the ITB cross-sectional area (ITBCSA) a new morphological parameter to assess ITBFS. @*Methods@#Forty-three patients with ITBFS group and from 43 normal group who underwent T1W magnetic resonance imaging were enrolled. The ITBCSA was measured as the cross-sectional area of the ITB that was most hypertrophied in the magnetic resonance axial images. The ITBT was measured as the thickest site of ITB. @*Results@#The mean ITBCSA was 25.24 ± 6.59 mm 2 in the normal group and 38.75 ± 9.11 mm 2 in the ITBFS group. The mean ITBT was 1.94 ± 0.41 mm in the normal group and 2.62 ± 0.46 mm in the ITBFS group. Patients in ITBFS group had significantly higher ITBCSA (P < 0.001) and ITBT (P < 0.001) than the normal group. A receiver operator characteristic curve analysis demonstrated that the best cut-off value of the ITBT was 2.29 mm, with 76.7% sensitivity, 79.1% specificity, and area under the curve (AUC) 0.88. The optimal cut-off score of the ITBCSA was 30.66 mm 2 , with 79.1% sensitivity, 79.1% specificity, and AUC 0.87. @*Conclusions@#ITBCSA is a new and sensitive morphological parameter for diagnosing ITBFS, and may even be more accurate than ITBT.

ABSTRACT

Purpose@#The purpose of this study was to assess the knowledge and health beliefs about gestational diabetes and to identify the influence on breastfeeding intention of women those who have been diagnosed with gestational diabetes. @*Methods@#A cross-sectional descriptive study was designed. A questionnaire survey was conducted on 270 women who were pregnant and currently diagnosed with gestational diabetes. Data collection was conducted at Internet cafes and breastfeeding clinics where pregnant women were able to participate actively. The data collection period was from November 5 to November 27, 2019 and analyzed using descriptive statistics, independent t-test, x 2 test and multiple logistic regression. @*Results@#The average age of the participants was 34.21±3.73 years. There were 221 women who had breastfeeding intention, and 49 women who did not intend to breastfeed. The higher the perceived susceptibility (OR=2.49, p=.032), benefits (OR=2.62 p=.009), and the self-efficacy, the higher the intention to perform breastfeeding (OR=2.97, p=.004). On the other hand, the higher the perceived severity, the lower the intention to perform breastfeeding (OR=0.35, p=.007). Conclusion: Health beliefs such as perceived susceptibility, perceived benefits, self-efficacy and perceived severity have been shown to affect the breastfeeding intention. Based on these results, we suggest developing a breastfeeding promotion intervention program that improves self-efficacy in gestational diabetics.

ABSTRACT

Purpose@#Intertrochanteric fractures can be treated using proximal femoral nail antirotation (PFNA). This study examined the clinical and radiological results of the intraoperative fracture compression. @*Materials and Methods@#Ninety-four patients underwent intraoperative compression (Group I), and 88patients underwent natural sliding only (Group II). The patients were followed-up for more than two years. All patients met the following seven conditions: (1) AO/OTA 31-A1, A2 type intertrochanter fracture, (2) availability of compression of more than one cortical bone in the anterior or medial regionof the fracture site under the preoperative imaging test, (3) Singh index grade ≥3, (4) blade position: center-center, center-inferior, (5) tip-apex distance <25 mm, (6) reduction status of good or very good, and (7) positive or neutral medial cortical support position with slightly valgus reduction. @*Results@#A slight tendency toward significant differences in acute phase pain between the two groups was observed at six weeks postoperatively (p=0.073). Twenty-four months after surgery, lateral extension of the PFNA helical blade between the two groups showed significant differences (p=0.017). Fracture gaps measured immediately after surgery showed significant differences (p=0.001), and a clear tendency for a significant difference in the average fracture union time was found (p=0.065). @*Conclusion@#Intraoperative fracture compression, intraoperative fracture compression appears beneficial to achieve a successful union of trochanteric fractures provided that all conditions are met to apply the method safely.

ABSTRACT

An 84-year-old female visited with an intertrochanteric femoral fracture. The patient had undergone an open reduction and internal fixation with a compressive plate and elastic nail in an ipsilateral atypical diaphyseal femoral fracture in the past. Compressive plate and elastic nail remained, and anterolateral bowing was presented. To treat the periprosthetic trochanteric fracture, a proximal femoral nail was used without removing the previously inserted compressive plate. Under the “rendezvous” technique, using a combination of fixating intramedullary nail and compressive plate simultaneously, the distal screw was fixed, and a femoral head lag screw was inserted after reducing the fracture. Complete union of the fracture was achieved 16 months after the operation, and a decrease in mobility function was not found postoperatively. The authors report this case for the “rendezvous” technique as a treatment option for elderly patients with periprosthetic trochanteric fractures, who had previously undergone surgical treatment for ipsilateral atypical diaphyseal femoral fractures with anterolateral bowing.

ABSTRACT

We report on the case of a patient with chronic instability of the ball-and-socket ankle joint. The patient, a 21-year-old male, was diagnosed 10 years previously with chronic instability of the ball-and-socket ankle joint. He underwent Broström procedure and augmentation using a periosteal turn down from the fibula for this chronic instability despite having received conservative treatment since the diagnosis. After the procedure, the clinical symptoms of ankle instability were improved and the patient is being periodically followedup. We report on this case of using a Broström procedure as a treatment option for patients with instability of the ball-and-socket ankle joint with normal range of foot and normal ankle joint alignment without damage in the joint and cartilage.

ABSTRACT

PURPOSE: The purpose of this study was to compare the clinical and radiological outcomes of locking compression plate (LCP)-screw fixation and tension band wiring (TBW) fixation in isolated lateral malleolar fractures.MATERIALS AND METHODS: From May 2016 to August 2018, 52 patients with isolated lateral malleolar fracture were retrospectively reviewed. They were divided into 30 cases of the LCP fixation group (Group I) and 22 cases of the TBW fixation group (Group II). The clinical and radiological results of those groups were compared. Pearson chi-square tests and independent t-tests were used in the statistical analysis.RESULTS: The mean length of the surgical incision was 8.3 cm in Group I and 4.9 cm in Group II. Radiological union was obtained at a mean of 8.4 weeks in both groups. The mean American Orthopaedic Foot and Ankle Society score was 90 (range, 85–97) and 92 (range, 85–100) in Groups I and II, respectively, at the last follow up.CONCLUSION: Both the LCP-screw and TBW techniques revealed excellent results in isolated lateral malleolar fractures. The tension band technique may be a fine alternative method of fixation in the treatment of isolated lateral malleolar fracture.

ABSTRACT

The acquisition of somatic mutations is the most common event in cancer. Neoantigens expressed from genes with mutations acquired during carcinogenesis can be tumor-specific. Since the immune system recognizes tumor-specific peptides, they are potential targets for personalized neoantigen-based immunotherapy. However, the discovery of druggable neoantigens remains challenging, suggesting that a deeper understanding of the mechanism of neoantigen generation and better strategies to identify them will be required to realize the promise of neoantigen-based immunotherapy. Alternative splicing and RNA editing events are emerging mechanisms leading to neoantigen production. In this review, we outline recent work involving the large-scale screening of neoantigens produced by alternative splicing and RNA editing. We also describe strategies to predict and validate neoantigens from RNA sequencing data.

ABSTRACT

Arterial stiffness in endurance athletes is low, whereas arterial stiffness in strength athletes is high. The adaptation of the arterial stiffness may be different depending on the training type. On the other hand, there are mixed-trained athletes that can’t be classified as endurance- or strength- trained athletes. The aim of this study was to investigate the arterial stiffness among mixed-trained athletes. The total of 51 young male athletes (15 long-distance runners, 10 handball players and 26 kendo players) and 16 young healthy sedentary individuals (control group) participated in this study. Carotid-femoral pulse wave velocity (cfPWV), carotid-brachial PWV (cbPWV) and femoral-ankle PWV (faPWV), were measured as indices of central and peripheral (upper and lower limbs) arterial stiffness, respectively. cfPWV showed significantly lower in long-distance runners (high endurance capacity) and handball players (strength and high endurance capacities) compared with kendo players (strength and low endurance capacities) and control groups (P < 0.05 for both). cbPWV showed significantly lower in handball players and kendo players compared with the control group (P < 0.05 for both). There was no difference in faPWV among the groups. These data suggest that the competitive characteristics of athletes (i.e., endurance capacity or target muscle groups of sport) influence the adaptation of arterial stiffness. It can be speculated that endurance capacity in mixed-trained athletes can affect central arterial stiffness and similar to endurance trained athletes. In addition, the adaptation in upper limb arterial stiffness will be included in the training effects associated with the sports-specific target muscle groups, while lower limb arterial stiffness may not be unaffected by any type of exercise.

ABSTRACT

PURPOSE: This article is a comprehensive review for concept clarification of critical thinking, clinical reasoning, and clinical judgment, which still lack a consensus and are of mixed use. METHODS: Norris's method of concept clarification was used to review concepts that have no clear definition or conceptualization yet. RESULTS: This review summarized literature from various disciplines, classified each concept based on similarities and differences, and provided hypothetic conceptual schema. CONCLUSION: Clinical reasoning and clinical judgment are clinical situation specific concepts, while critical thinking is a concept applied in general situations. Critical thinking is a broader concept and serves as a foundation for clinical reasoning and clinical judgment. Clinical reasoning precedes clinical judgment. Clinical judgement implies the end point or conclusion of clinical reasoning. Each of critical thinking, clinical reasoning, and clinical judgment is a cognitive and affective process not a psychomotor process. The concept of clinical competency involves action taken after the cognitive processes of clinical reasoning and clinical judgment.

ABSTRACT

We report successful resuscitation of a patient after cardiac arrest on postoperative day 4 after coronary artery bypass grafting (CABG). The patient underwent proximal right coronary artery stent insertion 1 year preceding his CABG, and in-stent restenosis of the stent was found on coronary angiography (CAG). CABG was planned. The patient was treated with a nitroglycerin (NTG) for chest pain, and in the holding area of the operating theater, his chest pain resumed during brief cessation of the NTG while changing the syringe pump. Intraoperatively, normal flow was confirmed at the graft site with flowmetry, while the patient received a NTG infusion. On postoperative day 4, the patient developed chest pain and a subsequent cardiac arrest. He was resuscitated with chest compressions alone, and emergent CAG was performed. It showed coronary artery spasm of the left anterior descending coronary artery, confirmed by provocation testing. The patient was discharged with symptoms well controlled on oral medications.

ABSTRACT

Aortic pseudoaneurysm after cardiac surgery is a rare entity, but it is potentially fatal due to its clinical course along with higher morbidity and mortality rates. Instead of open surgical repair, percutaneous procedures have been introduced as other options for managing an aortic pseudoaneurysm. In this case report, we describe transesophageal echocardiography guidance for successful percutaneous closure of an aortic pseudoaneurysm located in the left ventricular outflow tract by using a type II Amplatzer vascular plug in a patient in whom open surgical repair was not recommended.
