Cranial implants are commonly used throughout the world, yet the data on complications remain partly clarified. The aim of this study was to gather real data in 2018 on complications related to cranial implants in neurosurgery. The survey population consisted of 1103 institutes supplying neurosurgical treatment. The survey consisted of two-stage questionnaire. First the incidence of complications was investigated, then the secondary questionnaire was e-mailed to the respondents about the detailed of the complications. As the result, the annual incidence of complications related to cranial implants was 0.558% in Japan. Titanium plate and mesh were used predominantly in craniotomy and cranioplasty, respectively. The second survey collected data on 449 cases with complications (infection 63%, implant exposure 46%, multiple answer). Postoperative infection was associated with male sex, brain tumor, short interval between surgery and complication, usage of ceramics, hydroxyapatite, resin, and artificial dura, hyponutrition, multiple surgeries, dirty wound, and sinusitis as patient factors, and CSF leakage, ruptured sutures, and sinus maltreatment as surgery factors. Meanwhile, long hospital stay was associated with age, male sex, mRS 3-5 before complication, short interval between initial surgery and complication, large craniotomy, long operative time, usage of ceramics and artificial dura, multiple surgeries and dirty wound as patient factors, ruptured suture as a surgical factor, and bacterial infection, especially MRSA infection, as the complication and treatment consisting of removal as complication factors. In conclusion, this is the first Japanese national survey on complications related to cranial implants in neurosurgery. It is important to recall that complications may arise years after surgery and to be aware of the risk factors associated with complications.Some of the pediatric moyamoya patients spend their childhood without diagnosed as moyamoya disease (MMD) because of their mild ischemic attacks and emerge again with ischemic or hemorrhagic stroke in their adulthood. This study was aimed to clarify the clinical characteristics of adult moyamoya patients with childhood onset and elucidate the impact of long disease period on their clinical features. Present study included 116 untreated hemispheres of 69 adult patients with MMD. They were divided into two groups childhood onset group (26 hemispheres of 14 patients) and adult onset group (90 hemispheres of 55 patients). Clinical features were compared between the two groups. The incidence of hemorrhagic stroke was significantly higher in childhood onset group (P = 0.0091). Lenticulostriate and choroidal channels were more developed in childhood onset group (P = 0.044 and P less then 0.001, respectively). Vault moyamoya was more frequently observed in childhood onset group (P less then 0.001). The development of surgical collaterals through indirect bypass was more marked in childhood onset group (P = 0.0019). Multivariate analysis revealed that childhood onset and developed choroidal channels were significantly associated with the occurrence of hemorrhagic stroke (OR 4.31 [95% CI 1.21-15.4], P = 0.025 and OR 6.78 [95% CI 1.78-25.8], P = 0.0050, respectively). This study clearly shows that adult moyamoya patients with childhood onset have more developed spontaneous collaterals, which may, in turn, highly causes hemorrhagic stroke. Adult moyamoya patients with "childhood onset" should be recognized as a novel and important concept when elucidating the underlying mechanisms of hemorrhagic stroke in MMD.An isolated fourth ventricle (IFV) is characterized by fourth ventricular dilation due to obstruction of its inlet and outlet. A disproportionately large communicating fourth ventricle (DLCFV) is a rare subtype of IFV, characterized by dilation of the fourth ventricle, regardless of the size of the lateral ventricles, with no apparent obstruction of the cerebral aqueduct. To our knowledge, this is the first case series describing endoscopic diagnosis and treatment strategy for DLCFV. We retrospectively reviewed six cases of DLCFV in which endoscopic surgery was performed at our institution and affiliated facilities between June 2013 and March 2017. DLCFV was diagnosed using radiographic imaging and intraoperative endoscopy. We also conducted a PubMed search and included only original studies related to DLCFV treatment written in English in our review of the literature. Endoscopic third ventriculostomy (ETV) was performed in all patients. Additional endoscope-assisted placement of a fourth ventriculoperitoneal (VP) shunt was performed in two patients who could not be managed with ETV alone because of severe adhesion of the interpeduncular cistern due to subarachnoid hemorrhage (SAH). The patients' symptoms and the size of the fourth ventricle improved with surgical treatment, without complications. Endoscopic surgery for DLCFV appears to be a safe and effective treatment. read more Based on our treatment strategy, ETV is the first-line treatment for DLCFV. Endoscope-assisted placement of the fourth VP shunt can be treatment for severe adhesion of the interpeduncular cistern.Propionibacterium acnes (P. acnes) is a commensal bacterium indigenous to the skin. Previous reports have suggested that infection with P. acnes causes sarcoidosis, a systemic granulomatous disease. We present the case of a 63-year-old woman who developed subcutaneous nodules. A skin biopsy revealed necrotizing vasculitis and noncaseating granulomas, which are characteristic of sarcoidosis. Immunohistostaining revealed a P. acnes skin infection, which led to the diagnosis of sarcoidosis. Minocycline treatment resolved the infection and improved the patient's symptoms. We herein report a case in which immunohistochemistry was useful in the diagnosis of sarcoidosis.Autologous hematopoietic recovery after allogeneic hematopoietic cell transplantation (allo-HCT) is rare in patients who receive myeloablative conditioning (MAC). Autologous hematopoietic recovery suggests graft rejection, leading to concerns about subsequent disease relapse. We herein report a rare case of a patient with acute leukemia who experienced autologous hematopoietic recovery after cord blood transplantation (CBT) with total body irradiation-based MAC. Chromosomal abnormalities were repeatedly detected without any disease relapse for eight months. The accumulation of similar cases is required to accurately assess the incidence and clinical outcomes of autologous hematopoietic recovery after CBT with MAC.We report the case of a 56-year-old man with chronic myeloid leukemia (CML) who developed dasatinib-induced interstitial lung disease (ILD) 7 years after starting dasatinib, a BCR-ABL1 inhibitor. The patient presented with dyspnea. Chest imaging showed diffuse ground-glass opacities. A surgical lung biopsy showed cellular non-specific interstitial pneumonia (NSIP). Corticosteroid treatment ameliorated his condition. Bosutinib, another BCR-ABL1 inhibitor, was successfully re-instituted. The present case and relevant literature suggest that dasatinib-induced ILD can present as NSIP after an extended period, responds to corticosteroids, and is amenable to re-challenge at a lower-dose or with alternative BCR-ABL1 inhibitors.Eosinophilic gastroenteritis (EGE)-associated duodenal ulcer is rare and its endoscopic and pathological features remain poorly described. A 15-year-old boy was referred to our hospital for further examination and treatment of duodenal ulcer. Esophagogastroduodenoscopy (EGD) revealed two A2-stage duodenal ulcers on the duodenal bulb. A biopsy revealed marked infiltration of eosinophils, suggestive of EGE-associated duodenal ulcers. Thus, treatment with crushed budesonide (9 mg/day) was started. EGD revealed healing of the duodenal ulcers seven months after treatment. To our knowledge, this is the first report describing EGE-associated duodenal ulcer successfully treated with crushed budesonide.Infectious disease with various presentations in systemic lupus erythematosus (SLE) often resembles lupus flare. A 37-year-old woman presented with a swollen left index finger that had not resolved, despite 7 years of immunosuppressive treatment. MRI showed rice-body formation in the flexor tendon sheath and tenosynovectomy demonstrated chronic synovitis with epithelioid granuloma. A mycobacterial culture confirmed invasive mycobacterial tenosynovitis due to Mycobacterium chelonae. The patient was treated with moxifloxacin and clarithromycin and completely recovered.A 59-year-old man with type 1 diabetes presented with heart failure. Echocardiography showed large vegetations on the mitral and aortic valves. Blood bacterial culture was positive for Staphylococcus warneri, a coagulase-negative staphylococcus (CoNS) family member. He was diagnosed with native valve endocarditis (NVE) induced by the resident bacteria and ultimately underwent double valve replacement. Retrospectively, slight laboratory data abnormalities and weight loss beginning four months before may have been signs of NVE. He had no history of immunosuppressive therapies or medical device implantation. Thus, CoNS can cause NVE after a long asymptomatic course in patients with poorly controlled diabetes.Sarcoidosis is a multisystem granulomatous disease of unknown etiology and is pathologically characterized by non-caseating granulomas in the organs involved. We herein report a case of sarcoidosis in a Japanese woman with acute respiratory failure, diagnosed using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) on the ventilator after intubation. Only a few cases of previously undiagnosed sarcoidosis presenting acute respiratory failure have been reported. It is important to be aware that undiagnosed sarcoidosis may present with acute respiratory failure. Therefore, EBUS-TBNA under mechanical ventilation may be useful for the immediate diagnosis of patients.A 60-year-old man presented with postoperative recurrence of intrahepatic cholangiocarcinoma with right portal vein tumor thrombosis (PVTT). After failure of standard chemotherapy, a liver biopsy showed that his microsatellite instability (MSI) status was high. Treatment with the immune checkpoint inhibitor (ICI) pembrolizumab was commenced, which resulted in a partial response and resolution of the PVTT. There were no significant immune-related adverse events. According to recently published reports, the frequency of MSI-high biliary tract cancer (BTC) is about 0%-2.1%, which is extremely rare. However, ICIs may be effective in patients with MSI-high BTC, such as the present patient.We herein report a woman diagnosed with cardiac sarcoidosis (CS) based on the presence of epithelioid granulomas in non-cardiac organs and clinical findings including sustained ventricular tachycardia (VT) and cardiac dysfunction. She stopped oral corticosteroid after 4 years of treatment, and an abnormal myocardial uptake of fluorine-18 fluorodeoxyglucose and sustained VT recurred 3.5 years later. There is no consensus concerning whether or not corticosteroid therapy should be discontinued in the treatment of CS. As a relapse of sarcoidosis-related inflammation may be associated with life-threatening arrhythmia, some patients should continue corticosteroid therapy, even at low doses.
