Study Design: This is a retrospective study.Purpose: This study aimed to investigate the incidence of and risk factors for postoperative shoulder imbalance (PSI) in patients with Lenke type 1.Overview of Literature: PSI is a complication resulting in poor self-image and satisfaction in adolescent idiopathic scoliosis (AIS) patients.Methods: We examined the data of AIS patients with Lenke type 1 curves who underwent posterior fusion surgery in a retrospective manner. PSI was defined as a 2-year postoperative absolute radiographic shoulder height (RSH) of ≥2 cm. Patients were divided into two groups based on the presence of PSI and the level of their upper instrumented vertebra (UIV) (UIV at T2 or T3 [U-UIV] or UIV below T3 [L-UIV]). The radiographic parameters and clinical outcomes were compared, and the cutoff values of risk factors were identified by multivariate analysis.Results: Of 104 patients, 21 (20.2%) had left shoulder elevation PSI. The PSI group had a significantly greater preoperative RSH (−5.1 mm vs. −14.3 mm) and main thoracic (MT) curve correction rate (77.3% vs. 69.1%) than the non-PSI group. The PSI incidence did not differ between the U-UIV and L-UIV groups. Multivariate analysis identified preoperative RSH and the MT curve correction rate as independent risk factors for PSI. The receiver operating characteristic curve analysis identified the preoperative RSH cutoff value as −6.5 mm and MT curve correction rate cutoff value as 76.9%.Conclusions: Even in AIS patients with Lenke type 1 curves, the incidence of PSI was relatively high (20.2%). Patients with preoperative lower right shoulder elevation (i.e., RSH >−6.5 mm) had a higher risk of PSI regardless of UIV level when the MT curve showed a higher correction rate (i.e., correction rate >76.9%).

「に耐える」と「を耐える」の使い分け指導のための用例分析

본고는「に耐える」와「を耐える」의 용례 분석을 통해 그 용법 지도에 일조 하는 데 목적을 두고 있다. 기본적으로「耐える」는 助詞ニ와 연결된다. 그러나 "정신적 육체적 고통"을 나타내는 명사(명사구)인 경우 助詞ヲ도 연결될 수 있다. "외부로부터의 강한 작용"을 나타내는 명사도 마찬가지로 그것을 고통으로 느끼는 경우 助詞ニ와 함께 助詞ヲ도 연결된다. 시간을 나타내는 명사도 그 시간을 고통으로 간주하는 경우에는 助詞ニ도 助詞ヲ도 연결된다. 다만 시간을 나타내는 명사 중 그것이 구체적인 시간(숫자)인 경우 그 명사를 수식하는 내용이 없으므로「耐える」와 연결되는 조사를 생략할 수 있는 문장에서는 助詞ヲ만 연결된다. 한편 무생물인 경우 의인화(擬人化)하지 않으면 고통을 느끼지 못하기 때문에 助詞ニ만 연결된다. 그런 경우 대부분 무생물의 내구성을 나타낸다. 고통이 아니라 "능력이 있다" 혹은 "~할 만하다", "대단히 ~하다"와 같은 뜻인 경우도 助詞ニ만 연결된다. 이는 명사인 경우도 명사구인 경우도 마찬가지다. "마음속에서 일어나는 감정"을 나타내는 명사인 경우 助詞ヲ만 연결된다. 이는 본래「がまんする」나「こらえる」를 사용하는 것이 적절하기 때문에「がまんする」「こらえる」와 연결되는 助詞ヲ가 사용되는 것으로 사료된다.

Study Design: A retrospective study. Purpose: To investigate the incidence of iliac screw loosening with a two-rod vs. multi-rod construct and the effect on clinical and radiographic outcomes after surgery for adult spinal deformity (ASD). Overview of Literature: Multi-rod construct is useful for preventing rod fracture in ASD surgery. However, limited information is available regarding the incidence of iliac screw loosening after corrective fusion surgery using a multi-rod construct. Methods: Total 106 patients with ASD (24 men and 82 women; mean age, 68 years) who underwent corrective fusion surgery using bilateral iliac screws and were followed up for at least 1 year were reviewed. The following variables were compared between patients who underwent surgery with a two-rod and multi-rod construct: age, sex, bone mineral density (BMD), fusion level, high-grade osteotomy, L5/S interbody fusion, screw loosening (upper instrumented vertebra [UIV], S1, and iliac), rod fracture, proximal junctional kyphosis, spinopelvic parameters, and Oswestry Disability Index (ODI) score. We also compared patients with and without iliac screw loosening in the multi-rod construct group. Results: Of the 106 patients, 55 underwent surgery with a conventional two-rod construct and 51 with a multi-rod construct (three rods in 16, four rods in 35). Iliac and UIV screw loosening was observed in 24 patients (21%) and 35 patients (33%), respectively. The multi-rod group showed significantly higher incidence of iliac and UIV screw loosening and lower incidence of rod fracture. Patients with iliac screw loosening had a lower BMD than those without screw loosening; however, no significant differences were observed in the spinopelvic parameters or the ODI score. Conclusions: The use of multi-rod constructs led to a higher incidence of junctional screw loosening than the use of conventional two-rod constructs, especially in patients with osteoporosis. Iliac screw loosening did not affect sagittal alignment or clinical outcome in the short term.

Koji Kinoshita,Yuki Banno,Yuki Ono,Shohey Yamada,Mitsuru Handa 한국강구조학회 2019 International Journal of Steel Structures Vol.19 No.3

This study experimentally investigates eff ect of fatigue strength improvement of the Portable Pneumatic Needle-Peening treatment (PPP treatment) as a needle peening on out-of-plane gusset welded joints by using plate bending fatigue tests. This study also examined eff ect of the travel speed and the number of treatment passes of the PPP treatment with regards to its fatigue strength improvement. After the fatigue tests, the observation of the fracture surface with Scanning Electron Microscope was carried out in order to clarify the crack initiation. From those test results, it may be concluded that the eff ect of fatigue strength improvement might be governed by treatment passes with suffi cient travel speed. In addition, this study carried out additional fatigue tests that focus on fatigue crack closer by using the PPP treatment. As a result of additional fatigue tests for fatigue crack closure, it might be said that the eff ect of fatigue crack closure is eff ective when the distance between fatigue cracks and treatment area is less than 2.0 mm.

Fatigue Strength Improvement of Welded Joints of Existing Steel Bridges by Shot-Peening

Koji Kinoshita,Yuki Banno,Yuki Ono,Shohey Yamada,Mitsuru Handa 한국강구조학회 2019 International Journal of Steel Structures Vol.19 No.2

Shot-peening recently can be applied to existing steel bridges due to the development of new vacuuming techniques of shots after peening in the construction site. This study experimentally investigates eff ects of fatigue strength improvement of shot-peening on welded joints. Bending fatigue tests using out-of-plane gusset welded joints specimens were carried out and three type specimens were compared: as-welded, grit-blasted, and shot-peened. In addition, this paper examines diff erences of fatigue strength improvement eff ects in case of applying shot-peening to inside of scallop where shots might be diffi cult to hit perpendicularly to weld toe of welded joints because of narrow space, and the residual stress measurement in order to clarify introducing compressive residual stress were carried out. As a result, it may be concluded that shot-peening can improve fatigue strength of welded joints and its mechanism was identifi ed as extension of crack initiation life and delay crack propagation due to benefi cial compressive residual stress in the vicinity of surface layer.

ObjectiveTransvaginal removal of large specimens during laparoscopic hysterectomy can be a complex surgical procedure thatposes a risk of organ injury and tissue spillage into the abdominal cavity and is associated with extraction of thespecimen and manual morcellation. Our objective was to demonstrate a technique for transvaginal removal of largespecimens using the Alexis Contained Extraction System (CES) in laparoscopic hysterectomy. MethodsThe technique used for transvaginal removal of large specimens using the Alexis CES was presented in this video. Surgery was performed at a tertiary hospital. ResultsFollowing resection of the specimen during laparoscopic hysterectomy, the Alexis CES was inserted into the abdominalcavity through the umbilical trocar wound. The specimen was placed in a bag to prevent tissue spillage. The ringretractor was guided to the vagina and pulled out transvaginally. By repeatedly turning the ring retractor, tensionwas applied to the specimen bag, and the vaginal wall was unfolded all around to enable a secure surgical field. During manual morcellation of the specimen in the bag, the retractor was pulled and additionally turned to roll andre-tension the specimen bag when the bag was loosened. The specimen was pushed out of the vagina and safely andeffectively extracted without concerns about tissue spillage in the abdominal cavity or related organ injuries. ConclusionThe technique for transvaginal removal of large specimens using the Alexis CES enables simple, effective, and safetissue extraction with contained manual morcellation during laparoscopic hysterectomy. 영어

Current state and outlook for drug repositioning anticipated in the field of ovarian cancer

Yusuke Kobayashi,Kouji Banno,Haruko Kunitomi,Eiichiro Tominaga,Daisuke Aoki 대한부인종양학회 2019 Journal of Gynecologic Oncology Vol.30 No.1

Ovarian cancer is the seventh most common cancer and the eighth most common cause of cancer mortality in women. Although standard chemotherapy is the established treatment for ovarian cancer, the prognosis remains poor, and it is highly anticipated that new drugs will be developed. New drugs, such as humanized anti-vascular endothelial growth factor monoclonal antibodies and poly ADP-ribose polymerase inhibitors, are expected to improve clinical outcomes of ovarian cancer. However, long-term, costly research is required to develop such new drugs, and soaring national healthcare costs are becoming a concern worldwide. In this social context, drug repositioning, wherein existing drugs are used to develop drugs with new indications for other diseases, has recently gained attention. Because trials have already confirmed the safety in humans and the pharmacokinetics of such drugs, the development period is shorter than the conventional development of a new drug, thereby reducing costs. This review discusses the available basic experimental and clinical data on drugs used for other types of cancer for which drug repositioning is anticipated to repurpose the drug for the treatment of ovarian cancer. These include statins, which are used to treat dyslipidemia; bisphosphonate, which is used to treat osteoporosis; metformin, which is used to treat diabetes; non-steroidal anti-inflammatory drugs; ivermectin, an antiparasitic agent; and itraconazole, an anti-fungal agent. These drugs will play an important role in future drug repositioning strategies for ovarian cancer. Furthermore, drug repositioning is anticipated to extend not only to ovarian cancer treatment but also to ovarian cancer prevention.

Rectal mobilization for laparoscopic pelvic lymphadenectomy of the lower paracervical pathway in patients with uterine cancer

( Iori Kisu ),( Hidetaka Nomura ),( Miho Iida ),( Kouji Banno ),( Tetsuro Shiraishi ),( Moito Iijima ),( Kayoko Nakamura ),( Kiyoko Matsuda ),( Nobumaru Hirao ) 대한산부인과학회 2021 Obstetrics & Gynecology Science Vol.64 No.6

Objective The pelvic lymphatic drainage system comprises the upper and lower paracervical pathways (LPPs). Lymph node dissection of the LPP, including the cardinal ligament, internal iliac, internal common iliac, and presacral lymph nodes, requires higher surgical skills because of the anatomical limitations of the pelvic cavity and the dissection of vessels while preserving the nerves in the pelvic floor. In this video, we demonstrate rectal mobilization for laparoscopic complete pelvic lymph node dissection of the LPP in patients with uterine cancer. Methods Rectal mobilization was performed before complete pelvic lymph node dissection of the LPP. The pararectal space was opened widely and the connective tissue between the presacral fascia and prehypogastric nerve fascia was dissected bilaterally, allowing the rectum to be pulled. Results This procedure created a wide-open space in the pelvic floor, allowing clear visualization of the nerves and lymph nodes of the LPP. Laparoscopic complete lymph node dissection of the LPP was performed in the open space while preserving the hypogastric and pelvic splanchnic nerves and isolating the extensive network of blood vessels in the pelvic cavity. Conclusion Rectal mobilization enabled the safe execution of laparoscopic complete pelvic lymph node dissection of the LPP in patients with uterine cancer.
