Meningiomas are common spinal tumor and mostly located at intradura. Recurrence rate after surgery for extradural meningioma was higher than intradural meningioma. A patient with intra and extradural spinal meningioma was treated and discussed its features and clinical management. A 41-year-old woman noted numbness of bilateral legs, gait disturbance, and mild bladder disturbance for over the two-month period. Magnetic resonance imaging revealed an epidural mass at T8-9 involving the dura mater from the left side...

Strangulated intestinal obstruction is one of the most common types of acute abdomen and requires urgent surgical treatment. Herein, we report a very rare case of strangulated intestinal obstruction caused by an ileo-ileal knot. An 80-year-old woman was admitted to our hospital with suspicion of strangulation ileus and underwent emergency laparotomy after investigation by exploratory single-port laparoscopy. During surgery, a small bowel gangrene caused by an ileo-ileal knot was found. The gangrenous segment was resected, and primary anastomosis was performed...

Non-arteritic anterior ischemic optic neuropathy (NAION) is a disease with microvascular abnormality that causes acute optic disc swelling (ODS) and, in severe cases, subretinal fluid (SRF) accumulation. ODS causes compartment syndrome and subsequent axonal degeneration and loss of retinal ganglion cells by apoptosis. No treatment modalities have been effective, although some cases improved after the intake of oral systemic steroids. We reported a case of a 72-year-old man who was referred due to a visual defect in the right eye...

Meningioma is typically considered to be a benign tumor. Malignant transformation and metastasis of meningiomas are rare. Moreover, most meningiomas are intracranial, and there are few reports on intraspinal meningiomas. This report aimed to describe the clinical features and pathological findings of a case of malignant transformation and distant metastasis of intraspinal meningioma, with a review of the literature. A 44-year-old man with a bilateral lower limb paresis was diagnosed with an intradural extramedullary tumor of the thoracic spine...

Cervical chylomas are rare pseudocystic collections that lack an epithelial lining and arise from the thoracic duct or its tributaries; although they typically develop after neck surgery or trauma, they can arise from unknown causes. Treatment options include not only conservative therapy, such as dietary modification, repeated aspirations, and sclerotherapy, but also include surgical excision. We describe a case of a chyloma in a 64-year-old Japanese woman with squamous cell carcinoma of the gingiva. The chyloma developed following left segmental mandibulectomy with radical neck dissection and reconstruction, using a titanium plate and a pectoralis major myocutaneous flap...

A 65-year-old man was referred to our hospital for the treatment of a lesion on the medial lacrimal canthus of both eyes. He had a history of perinuclear anti-neutrophil cytoplasmic antibodies, i.e., pANCA-positive interstitial pneumonia. Orbital magnetic resonance imaging excluded space occupying lesions, and laboratory testing excluded thyroid-related diseases. The masses were excised, and histopathological examinations showed sebaceous gland hyperplasia and inflammatory changes around the gland. In addition, the specimen from the left eye showed a retention cyst possibly caused by an infection...

Aneurysm formation is a potential complication of granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis. It is a very rare complication, but immediate diagnosis and therapy should be performed because an aneurysm can be life-threatening if it ruptures. An accessory left gastric artery (ALGA) is also a rare variant gastric artery that may obtain its blood supply from the left hepatic artery and left gastric artery. We herein describe a 57-year-old Japanese man who was diagnosed with GPA complicated by aneurysm rupture in an ALGA...

A 79-year-old woman was diagnosed with osteoarthritis of the left hip and scheduled for total hip arthroplasty. As two lesions were detected in branches of the coronary arteries, she was treated with catheter treatment. The patient was receiving anticoagulant treatment, which was suspended eight days before the operation; however, heparin was started at 6 days before the operation and was stopped 9 hours before the operation. On the 2nd postoperative day soon after transfer to the wheel chair, she was feeling unwell and was suffering from severe pain in her left buttock and left thigh...

The World Health Organization (WHO) Traditional Medicine Strategy (2014-2023) aimed to help member states promote the safe and effective use of traditional medicine. While economic conditions have markedly improved in Bangladesh, the country is experiencing significant public health problems. Because of limited medical resources, there is a strong incentive to enhance complementary and alternative medicine usage in Bangladesh. Therefore, this study aimed to confirm the perceptions and attitudes of medical doctors (MDs) in Dhaka, Bangladesh, with regard to Ayurvedic medicine (AM)...

Molecular profiling subgrouped medulloblastoma (MB) into four subtypes featured by distinct footprints. However, germline studies on genetic susceptibility in Chinese population have not been reported. To investigate the correlation of polymorphisms involved in the AKT signaling pathway with clinicopathological parameters in pediatric MB, and their contribution to the clinical outcome, we performed a case-controlled cohort consisting of 48 patients with pediatric MB and 190 healthy controls from Han population...

The Japanese Orthopaedic Association has proposed the term "locomotive syndrome" to designate a condition that places a person at high risk for long-term care. However, in daily clinical practice, even when a diagnosis of locomotive syndrome is made, exercise therapy often cannot be successfully performed in some patients owing to their lack of motivation. We speculated that locomotive syndrome and depressive states co-exist in elderly people. The purpose of this study was to determine the presence or absence of depressive states in older patients aged ≥ 65 years who were diagnosed with locomotive syndrome...

We sought to determine the short- and long-term prognoses among 'marginal-risk' non-small cell lung cancer patients who have a predicted postoperative- (ppo) forced expiratory volume in the first second (FEV1) of 30-60% and/or a ppo-diffusing capacity of the lung for carbon monoxide (DLCO) of 30-60%. The present study included 73 'marginal-risk' and 318 'normal-risk' patients who underwent anatomical resection for clinical stage I lung cancer between 2008 and 2012. The rates of postoperative morbidity, prolonged hospital stay, and overall survival were assessed...

Patients with acute leukemia are susceptible to chemotherapy-induced severe myelosuppression, and therefore are at a high risk for febrile neutropenia (FN). In such cases, the use of broad-spectrum antibiotics such as fourth-generation cephalosporins and carbapenems is recommended as first-line antimicrobial treatment; however, the effectiveness of these agents in patients with acute myeloid leukemia (AML) has not been investigated in detail. We retrospectively examined and evaluated the effectiveness of first-line antibiotic treatment regimens for chemotherapy-induced FN in patients with AML in Japanese Red Cross Nagoya Daiichi Hospital...

This study investigated the effects of switching from combination therapy with either alogliptin (Alo) or pioglitazone (Pio) to fixed-dose combination therapy (FDCT) with alogliptin and pioglitazone (Alo-Pio FDCT). The usefulness and efficacy of Alo-Pio FDCT were investigated. A total of 50 outpatients with type 2 diabetes mellitus (T2DM) treated with Alo and 47 outpatients with T2DM treated with Pio were switched to Alo-Pio FDCT, and its efficacy and usefulness were evaluated. Significant improvements were observed in hemoglobinA1c (HbA1c), alanine transaminase (ALT), and γ-glutamyl transpeptidase (GGT) levels after switching to Alo-Pio FDCT for 16 weeks in both groups...

REVIEW
Michihiko Sone
The inner and middle ear are connected mainly through round and oval windows, and inflammation in the middle ear cavity can spread into the inner ear, which might induce a disturbance. In cases with intractable otitis media, attention should also be paid to symptoms related to the inner ear. In this paper, middle ear inflammation and related inner ear disturbances are reviewed with a focus on representative middle ear diseases (such as acute otitis media, chronic otitis media, otitis media with anti-neutrophil cytoplasmic antibody-associated vasculitis, eosinophilic otitis media, cholesteatoma with labyrinthine fistula, and reflux-related otitis media)...

Aneurysms arising from the distal anterior inferior cerebellar artery (AICA) are very rare. When the parent artery is an AICA-posterior inferior cerebellar artery (PICA) variant, occlusion of the artery, even distal to the meatal loop, leads to a significant area of cerebellar infarction. We report two cases of ruptured partially thrombosed distal AICA aneurysms. In both cases, the parent artery was an AICA-PICA variant. The aneurysms were clipped in one case and trapped following occipital artery (OA)-AICA anastomosis in another case...

Pulmonary blastoma (PB) is a rare form of lung tumour and is accountable for 0.25-0.5% of primary pulmonary malignancies. Initially pulmonary blastoma was divided into three subtypes: biphasic pulmonary blastoma (BPB) consisting of an epithelial and mesenchymal component, well differentiated fetal adenocarcinoma (WDFA) built of well differentiated epithelium and a mesenchymal component and malignant pleuropulmonary blastoma (PPB). Prognosis in this type of cancer is really poor. We present a current review of literature and a clinical case report...

We report a long-term survivor of colorectal cancer who underwent aggressive, frequent resection for peritoneal recurrences. A 58-year-old woman was diagnosed with descending colon cancer. Resection of the descending colon along with lymph node dissection was performed in September 2006. The pathological findings revealed Stage IIA colorectal cancer. The following peritoneal recurrences were removed: two in July 2007, two in the omental fat and two in the pouch of Douglas in June 2008 resected by low anterior resection of the rectum, one in the uterus and right ovarian recurrence resected via bilateral adnexectomy and Hartmann's procedure in May 2011, and one in the ascending colon by partial resection of the colon wall in December 2011...
