The present report describes the first known, case of a pseudoaneurysm of the perforating branch of the deep femoral artery following anterior cruciate ligament (ACL) reconstruction. A 19-year-old man underwent ACL reconstruction using the outside-in femoral tunnel-creation method. Seven days after the surgery, he complained of abnormal thigh pain and had swelling with local heat on the distal lateral thigh. Magnetic resonance imaging, computed tomography, and color Doppler ultrasonography showed the pseudoaneurysm in the thigh...

An 87-year-old Japanese man underwent percutaneous cryoablation (PCA) therapy for his renal cell tumor. We displaced the colon from the tumor using hydrodissection. Computed tomography (CT) immediately after PCA was indicative of iceball extension to the colon wall, and a discontinuous enhancement of the colon wall was observed. We therefore performed an emergency surgery. On laparotomy, we observed a dark-purple area on the affected area of the colon, and the resected specimen showed focal, deep ulceration on the mucosal surface...

We present the case of a 65-year-old Japanese man diagnosed with chronic empyema (without a bronchopleural fistula) that occurred 7 months after he underwent an extrapleural pneumonectomy for right malignant pleural mesothelioma (MPM). Following thoracic drainage and irrigation for 1 month, we performed surgery by a thoracoscopic approach, in light of his general condition. We performed debridement and removal of the Gore-Tex polytetrafluoroethylene (PTFE) patch that had been used for the reconstruction of the diaphragm and the pericardium...

Childhood anaplastic large cell lymphoma (ALCL) accounts for approx. 10-30% of cases of non-Hodgkin lymphoma, and the ALCL99 study reported 60-75 disease-free survival; however, a relatively high relapse rate was observed (25-30% ). We report 2 patients with Stage III ALCL who relapsed 6-18 months after the end of ALCL99 chemotherapy. A retrospective molecular analysis identified the nucleophosmin (NPM)-anaplastic lymphoma kinase (ALK) fusion gene in the first diagnostic bone marrow samples taken from both patients...

A 32-year-old woman, pregnant with twins, presented with a chief complaint of general fatigue. Her general condition had rapidly deteriorated since her last visit to the primary obstetrician; the patient was then referred to our hospital because of suspected fetal death. She underwent emergency cesarean section because fetal death had indeed occurred, and she was then admitted to the intensive care unit (ICU). On ICU admission, she was found to be in shock. Laboratory analysis revealed extreme hemoconcentration and a low albumin level, and initially, septic shock with obstetric complications was suspected...

Unexpected injuries can have a profound effect on a surgeon's performance and thus on patients and surgical departments. Here we describe a technique for performing surgery in the standing position, as done by a surgeon with an Achilles tendon rupture. During his prescribed 45-day non-weight-bearing period for the left ankle after surgery for an Achilles tendon rupture, the surgeon was able to participate in 15 surgeries as an operator or assistant, due to his use of a combination of injured-leg genuflection on a stool and a 'Surgical Body Support' device...

Interrupted aortic arch (IAA) is fatal if not diagnosed. Prenatal diagnosis is helpful, but it is difficult to detect IAA and even more so to differentiate types A and B prenatally. Our objectives were to find a way to detect IAA using 2 views-three-vessel view (3VV) and four-chamber view (4CV)-and to differentiate between types A and B. We retrospectively analyzed fetal echocardiographic images and medical records of eight IAA patients. All eight patients had a ventricular septal defect (VSD) on 4CV. The aorta/main pulmonary artery (Ao/MPA) diameter ratio on 3VV was significantly low, which is characteristic of type B IAA...

The metatarsophalangeal (MTP) joints are often and predominantly affected in rheumatoid arthritis. The aim of the current study was to describe surgical techniques of shortening oblique osteotomy for lesser metatarsal bone with screw fixation at the osteotomy site, and to investigate the short-term clinical outcomes of our procedure. Twenty-seven feet (78 toes) of 24 RA patients underwent the shortening oblique osteotomy for the correction of deformity at the lesser MTP joints. The average Japanese Society of Surgery of the Foot (JSSF) standard rating system for the RA foot and ankle scale improved significantly from 59...

The usefulness of endoscopy in marginal ulcer bleeding has rarely been studied, and the optimal method for preventing rebleeding is unclear. Here we assessed the efficacy of endoscopy in marginal ulcer bleeding and examined the efficacy of proton pump inhibitors (PPIs) in the prevention of rebleeding. A total of 28 patients with marginal ulcer bleeding (21 men, 7 women; median age 58.5 years) were treated by endoscopy. We analyzed the clinical characteristics, results of endoscopic therapy, characteristics of rebleeding patients, and relation between the use of PPIs and the duration of rebleeding...

Many patients suffer from postoperative serious adverse events (SAEs). Here we sought to determine the incidence of SAEs, assess the accuracy of currently used scoring systems in predicting postoperative SAEs, and determine whether a combination of scoring systems would better predict postoperative SAEs. We prospectively evaluated patients who underwent major surgery. We calculated 4 scores: American Society of Anesthesiologists physical status (ASA-PS) score, the Charlson Score, the POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity) score, and the Surgical Apgar Score (SAS)...

Postoperative cognitive dysfunction (POCD) occurs in nearly one-third of patients after non-cardiac surgery. Many animal behavior studies have investigated the effect of general anesthesia on cognitive function. However, there have been no studies examining the effects on working memory specifically, with a focus on the retention of working memory. We demonstrate here that isoflurane anesthesia induces deficits in the retention of spatial working memory in rats, as revealed by an increase in isoflurane- induced across-phase errors in the delayed spatial win-shift (SWSh) task with a 30-min delay in an 8-arm radial arm maze on post-anesthesia days (PADs) 1,2,4, and 10...

Metastatic epidural spinal cord compression (MESCC) is a common complication in patients with a malignant tumor, but it is difficult to decide the proper time to perform the necessary surgery. Here we analyzed the prognostic factors for postoperative walking ability. We retrospectively reviewed the cases of 112 MESCC patients treated surgically at our institute and divided them into ambulatory (n= 88) and non-ambulatory (n=24) groups based on their American Spinal Injury Association (ASIA) Impairment Scale grades at the final follow-up...

Concurrent meniscal repair with anterior cruciate ligament (ACL) reconstruction has shown good clinical outcomes, but it has a considerable risk of progressing to post-traumatic osteoarthritis of the knee. Here we investigated postoperative changes in the position of the lateral meniscus (LM) and assessed the short-term clinical results after concurrent LM repair with ACL reconstruction. Twentyseven patients underwent LM repair of a peripheral longitudinal tear concomitant with ACL reconstruction. We evaluated the preoperative and postoperative values of the Lysholm score and anteroposterior instability...

The urinary cross-linked N-terminal telopeptide of type I collagen (uNTx) levels in infantile osteogenesis imperfecta (OI) have not been well studied. Here we investigated the levels of uNTx in infants with OI and healthy infants. We collected spot urine samples from 30 infants with OI (male/female, 14/16; Sillence classification, I/II/III/IV: 15/3/6/6; age, 5.2±4.4 months) and 120 healthy infants (male/female, 75/45; age, 5.1±4.1 months) for the measurement of uNTx levels. The uNTx levels of the OI infants were significantly lower than those of the healthy infants (mean±SD, 1,363...

Chronic graft versus host disease (cGVHD) remains a major problem for long survivors after allogeneic hematopoietic stem cell transplantation (HSCT). Currently, corticosteroid therapy is effective for cGVHD as the first line therapy. However, prolonged therapy with corticosteroids causes various severe adverse events. To develop the new therapeutic strategy of cGVHD, we have launched a multicenter phase I/IIa clinical trial of low dose subcutaneous interleukin-2 (IL-2) for treatment of steroid refractory cGVHD, which is constituted of 2 sequential phases (induction phase and maitanance phase)...

Docetaxel is a standard treatment for patients with advanced or recurrent breast cancer. The recommended dose is 60 to 100 mg/m2. Previous study have shown that the tumor response rates of patients who received docetaxel monotherapy at doses of 60, 75, and 100 mg/m2 were 22.1% , 23.3% , and 36.0% , respectively, and there was a significant relationship between the dose and response. In Europe and the United States, docetaxel is approved at a dose of 100 mg/m2, and Japanese guidelines also recommend a dose of 100 mg/m2...

Stent placement is an essential treatment for airway diseases. Although self-expandable metallic stents and silicone stents are commonly applied for the treatment of airway diseases, these stents are unsuitable for the treatment of small airway diseases encountered in pediatric patients and lung transplant recipients with airway complications. Currently, only vascular balloon-expandable metallic stents are available for the treatment of small airway diseases; however, little research has been conducted on the use of these stents in this field...

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a standard procedure for precise histological diagnosis of pancreas tumors, but it is sometimes difficult to obtain adequate specimens. EUS Sonopsy CY® is a newly designed needle with original features. This randomized study will compare the tissue collection rate of EUS Sonopsy CY® to that of a conventional needle in EUS-FNA. The major eligibility criteria are as follows: Patients with a pancreatic mass referred for EUSFNA; age 20 years, and performance status<4...

Although accurate bracket placement is essential for orthodontic treatment, many practitioners apply brackets indiscriminately with direct or indirect bonding techniques. Nonetheless, there have been few prospective clinical comparisons of the 2 techniques. We will therefore conduct a single-center, randomized control trial in 100 patients aged 12 years and diagnosed with malocclusion. All patients will receive orthodontic treatment using brackets with direct or indirect bonding techniques. The primary endpoints will be the total treatment time, occlusal index, discomfort at bonding, and oral hygiene after bonding...

Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HSCT). Retinoic acid (tamibarotene) exerts multiple effects on cell differentiation and is clinically used for the treatment of acute promyelocytic leukemia. Tamibarotene down-regulates both Th1 and Th17 differentiation in donor T cells after allogeneic HSCT, resulting in attenuation of experimental chronic GVHD. Based on preclinical data, we have launched a phase II study of tamibarotene in patients with steroid-refractory chronic GVHD...
